Helio Corporation

2,000,000 Shares of Common Stock

We are offering 2,000,000 shares of common stock, assuming a public offering price of $4.50 per share (which is the midpoint of the estimated range of the public offering price). We currently estimate that the public offering price will be between $4.00 and $5.00 per share.

Our common stock is currently quoted on the OTC Markets OTCID tier, under the symbol “HLEO.” On October 19, 2026, the last reported closing price of our common stock on the OTCID was $4.50 per share. In connection with this offering, we have applied for the listing of our common stock on The Nasdaq Capital Market under the symbol “HLEO.” The closing of this offering is contingent upon our uplisting to The Nasdaq Capital Market and no assurance can be given that our application will be approved. Upon the completion of this offering, we anticipate that our executive officers and directors, together with Paul S. Turin, our Chief Engineer and a former director, and Stuart D. Bale, our Chief Scientist and a former director, will collectively be able to exercise approximately 48.98% of our total voting power (or approximately 47.06% if the underwriters exercise the over-allotment option in full). As a result, they will possess significant influence over the election of our board of directors and the approval or disapproval of significant corporate transactions, and may be able to determine the outcome of such matters, particularly if other stockholders do not vote or vote in different ways. Notwithstanding the foregoing, since no individual, company or persons acting as a group (as described in Section 13(d) of the Securities Exchange Act of 1934, as amended) will own a majority of our voting power, we will not be a “controlled company” under the corporate governance standards for companies listed on The Nasdaq Stock Market, or Nasdaq, although it is possible that we may become a “controlled company” in the future if such persons decide to form a group. See also “Risk Factors—Risks Related to this Offering and Ownership of Our Common Stock.”

We are an “emerging growth company” and “smaller reporting company” under the federal securities laws and have elected to comply with certain reduced public company reporting requirements. This prospectus complies with the requirements that apply to an issuer that is an emerging growth company. See “Prospectus Summary — Implications of Being an Emerging Growth Company and Smaller Reporting Company.”

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 10.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We have granted the underwriters an option for a period of 45 days after the closing of this offering to purchase up to 15% of the total number of shares to be offered by us pursuant to this offering (excluding shares subject to this option), solely for the purpose of covering over-allotments, at the public offering price less the underwriting discounts and commissions. If the underwriters exercise the option in full, the total underwriting discounts and commissions payable by us will be $724,500, and the total proceeds to us, before expenses, will be $9,625,500.

The offering price of our shares of common stock in this offering will be determined between us and the underwriters at the time of pricing, considering our historical performance and capital structure, prevailing market prices and conditions, and overall assessment of our business, and may be at a discount to the current market price. Therefore, the recent market price of our common stock and the public offering price of the common stock used throughout this prospectus for this offering may not be indicative of the actual offering price for the shares of common stock.

The underwriters expect to deliver the shares against payment as set forth under “Underwriting” on or about                   , 2026.

Our business, financial condition, results of operations, and prospects may have changed since that date.

We have not done anything that would permit this offering or possession or distribution of this prospectus in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus must inform themselves about and observe any restrictions as to this offering of securities and the distribution of this prospectus applicable to that jurisdiction.

The information provided in this prospectus contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. We obtained the industry and market data in this prospectus from our own research as well as from industry and general publications, surveys, and studies conducted by third parties. This data involves a number of assumptions and limitations and contains projections and estimates of the future performance of the industries in which we operate that are subject to a high degree of uncertainty, including those discussed in “Risk Factors.” We caution you not to give undue weight to such projections, assumptions, and estimates. Further, industry and general publications, studies, and surveys generally state that they have been obtained from sources believed to be reliable, although they do not guarantee the accuracy or completeness of such information.

On May 9, 2026, the Board of Directors approved a reverse stock split of our Common Stock at a ratio within the range of 1-for-1.25 to 1-for-5 (the “Reverse Stock Split”), and on May 11, 2026, holders of approximately 64.70% of the outstanding shares of Common Stock approved the Reverse Stock Split and the related amendment to the Company’s Articles of Incorporation by written consent in lieu of a special meeting. On July 7, 2026, the Board of Directors determined to effect the Reverse Stock Split at a ratio of 1-for-5. Prior to effecting the Reverse Stock Split, the Company filed and distributed to shareholders an Information Statement on Schedule 14C and observed the required 20-calendar-day waiting period under Regulation 14C. The Reverse Stock Split became effective on July 20, 2026, the effective date specified in the Articles of Amendment to the Company’s Articles of Incorporation filed with the Florida Department of State. Unless otherwise indicated, all share counts, per-share prices, and capitalization information in this prospectus have been retroactively adjusted to give effect to the Reverse Stock Split at the 1-for-5 ratio and are presented on a post-split basis. See “The Offering — Reverse Stock Split.”

In this prospectus, unless context requires otherwise, references to “we,” “us,” “our,” “Helio,” “Helio Corp.,” or the “Company” refer to Helio Corporation, a Florida corporation, and its consolidated subsidiaries. References to “Heliospace” refer to our wholly owned subsidiary, Heliospace Corporation, a Delaware corporation.

PROSPECTUS SUMMARY

The following summary highlights selected information contained elsewhere in this prospectus and is qualified in its entirety by the more detailed information and financial statements included elsewhere in this prospectus. It does not contain all the information that may be important to you in making an investment decision. You should carefully read this entire prospectus, including the matters set forth under “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and our financial statements and related notes included elsewhere in this prospectus.

Company Overview

Our wholly owned subsidiary, Heliospace Corporation (“Heliospace”), is an aerospace company specializing in the design, engineering, assembly, and test of space flight-qualified hardware, providing systems engineering, modeling, analysis, integration, and test services to customers in government, commercial, private, and non-profit markets. With deep expertise in civil space missions combined with a growing business serving commercial companies, our primary company objective is to enable humanity’s pursuit of the scientific and commercial development of space.

Heliospace designs, fabricates, assembles, and tests space-qualified hardware. Examples of this product line include the radar antennas for the NASA Europa Clipper mission, antennas for the SunRISE CubeSat constellation, and deployable systems and sensors for numerous lunar landers and the Mars Sample Return program. Heliospace also provides systems engineering, integration and test, and mission formulation services, including past support for the design, testing, and launch of the James Webb Space Telescope, the Roman Space Telescope, and other major NASA programs, and continuing with mission and payload systems engineering and design for privately funded missions. Heliospace has been operational since July 2018, servicing these and other contracts for government, private, and commercial customers.

Corporate History

Helio Corporation was incorporated under the original name Stirling Bridge Group, Inc. on October 3, 2022, in Florida. In May 2023, the Company changed its name to Web3 Corporation. In January 2024, by way of a reverse acquisition, the Company acquired 100% of the stock of Heliospace Corporation and changed its name from Web3 Corporation to Helio Corporation (the “Business Combination”). Heliospace was the accounting acquirer in the Business Combination and was determined to be the sole predecessor of Helio Corporation. Our principal executive offices are located at 2448 Sixth Street, Berkeley, CA 94710.

Market Overview

The global space marketplace is projected to grow from over $600 billion today to over $1.8 trillion by 2035 (World Economic Forum & McKinsey & Company, 2024). Our target markets include hardware, payloads, and infrastructure for Earth orbiting and lunar applications with a projected market size of $11-12 billion by 2030. Additional opportunities exist in space infrastructure for energy production, with a conservative market size of $0.7-0.8 billion today and expanding to $3-4.5 billion by 2030 (World Economic Forum & McKinsey & Company, 2024). Increased spending by government entities, rapidly increasing commercial activity, and strong demand for new solutions in the energy sector are strong drivers in market size growth.

Risks Relating to Our Financial Condition

Risks Relating to Our Business, Industry, and Strategy

Risks Relating to the Reverse Stock Split

Listing on Nasdaq

Our common stock is currently quoted on the OTCID under the symbol “HLEO.” In connection with this offering, we have applied to list our common stock on Nasdaq under the symbol “HLEO.” If our listing application is approved, we expect to list our common stock on Nasdaq upon consummation of this offering, at which point our common stock will cease to be traded on the OTCID.

Corporate Information

Implications of Being an Emerging Growth Company and Smaller Reporting Company

The Company is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) and a “smaller reporting company” as defined under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For so long as we remain an emerging growth company, we may avail ourselves of certain reduced disclosure requirements, including presenting only two years of audited financial statements and reduced executive compensation disclosure obligations. We may remain an “emerging growth company” until as late as the fiscal year-end following the fifth anniversary of the completion of our initial public offering (“IPO”), unless (a) we have more than $1.235 billion in annual revenue in any fiscal year, (b) the market value of our Common Stock held by non-affiliates exceeds $700 million as of any June 30, or (c) we issue more than $1.0 billion of non-convertible debt over a three-year period.

Recent Developments

Management Changes

Effective January 5, 2026, the Company appointed Edward Cabrera as Chief Executive Officer and Chairman of the Board, replacing Gregory T. Delory, who transitioned to the role of Chief Technology Officer and remains a member of the Board.

Change in Independent Auditor

On February 21, 2026, the Board dismissed Astra Audit & Advisory, LLC (“Astra”) as the Company’s independent registered public accounting firm. Astra’s reports on the Company’s consolidated financial statements for the fiscal years ended October 31, 2025 and October 31, 2024 included explanatory paragraphs expressing substantial doubt about the Company’s ability to continue as a going concern. On the same date, the Board engaged Hacker, Johnson & Smith PA (“HJS”) as the Company’s independent registered public accounting firm to audit the Company’s consolidated financial statements for the fiscal year ending October 31, 2026.

FirstFire Financing

On January 14, 2026, the Company entered into a Securities Purchase Agreement with FirstFire Global Opportunities Fund, LLC (“FirstFire”), pursuant to which the Company issued: (i) a Promissory Note in the principal amount of $165,000 (with a purchase price of $150,000 reflecting an original issue discount of $15,000) bearing interest at 10% per annum and maturing January 14, 2027 (the “FirstFire Note”), convertible into shares of our common stock at the lesser of (a) 80% of the lowest closing price during the ten trading days prior to conversion or (b) $2.50 per share (in each case, subject to adjustment), (ii) a warrant to purchase up to 66,000 shares of our common stock at an initial exercise price of $2.50 per share (the “FirstFire Warrant”), and (iii) 15,000 shares of our common stock as commitment shares (the “Commitment Shares”). The Company received net proceeds of $133,000 after deduction of $5,000 in legal fees and $12,000 in placement agent fees. The FirstFire Note has been fully satisfied as described below. The FirstFire Warrant was subsequently exercised in full by FirstFire via cashless exercise on March 12, 2026, resulting in the issuance of 52,640 shares of common stock. No FirstFire Warrant remains outstanding. The Commitment Shares remain outstanding. All FirstFire share and per-share amounts have been adjusted to give effect to the 1-for-5 Reverse Stock Split.

Pursuant to Amendment No. 1 to the FirstFire Note, the Company was obligated to file a registration statement covering the resale of the shares issuable upon conversion of the FirstFire Note, exercise of the FirstFire Warrant, and the Commitment Shares within 60 calendar days of April 1, 2026. As described below, the FirstFire Note has been fully satisfied and cancelled prior to the filing of this registration statement. Additionally, the FirstFire Warrant was exercised in full via cashless exercise on March 12, 2026, resulting in the issuance of 52,640 shares of common stock, and no warrant shares remain issuable. Accordingly, the resale registration obligations with respect to the FirstFire Note conversion shares and the FirstFire Warrant exercise shares are extinguished. The Commitment Shares remain outstanding but are not being registered for resale under this registration statement.

FirstFire Note Satisfaction

On or about April 29, 2026, the Company satisfied the FirstFire Note in full. The Company (i) repaid $150,000 in cash to FirstFire, and (ii) issued 20,000 shares of its common stock to FirstFire at a conversion price of $2.50 per share (the “FirstFire Repayment Shares”), representing a partial conversion of the remaining outstanding balance of the FirstFire Note. Upon receipt of the cash payment and issuance of the FirstFire Repayment Shares, the FirstFire Note was fully satisfied and cancelled. Although these actions resulted in the full satisfaction of the FirstFire Note, they were not effected pursuant to any formal settlement agreement. The FirstFire Repayment Shares were issued in reliance on Section 3(a)(9) of the Securities Act, as an exchange of the Company’s securities for its outstanding indebtedness, with no commission or other remuneration paid. The FirstFire Repayment Shares are restricted securities. Following such satisfaction, the obligations and restrictions under the FirstFire Note (including the mandatory use of financing proceeds under Section 1.10, the prohibition on Variable Rate Transactions, and the resale registration obligation under Amendment No. 1) are fully extinguished. The 15,000 Commitment Shares previously issued to FirstFire and the 52,640 shares issued to FirstFire upon the cashless exercise of the FirstFire Warrant on March 12, 2026 remain outstanding. No FirstFire Warrant remains outstanding.

Note Defaults

As of the date of this prospectus, the Company is not in default under any outstanding promissory note. As described in “Recent Developments - Wolf Settlement Agreement,” the two largest defaulted notes (original principal amounts of $400,000 and $500,000, respectively, matured November 5, 2025) were resolved pursuant to the Wolf Settlement Agreement dated April 27, 2026. The Amended and Restated Secured Promissory Note dated October 15, 2024, in the original principal amount of $250,000 (the “Cole Note”), which had matured on November 5, 2025 and was previously in default, has been resolved and is now current. Additionally, notes previously in default with original principal amounts of $50,000, $150,000, and $50,000, respectively, for which default notices were received in February 2026, have also been resolved and are now current. A convertible promissory note dated July 31, 2024 in the original principal amount of $250,000 (as amended and restated to $500,000), which was in default as of April 30, 2026, was resolved on June 13, 2026 pursuant to an agreement whereby the holder agreed not to pursue any default provisions in exchange for a payment plan (including a $20,000 initial payment and $15,000 monthly installments beginning July 15, 2026) and the transfer of 6,600 shares of common stock by Gregory T. Delory from shares personally owned by him (rather than an issuance by the Company).

Wolf Settlement Agreement

On April 27, 2026, the Company entered into a binding settlement agreement (the “Wolf Settlement Agreement”) with Sean Wolf (“Wolf”) via an exchange of emails, pursuant to which the Company and Wolf agreed to resolve and settle an aggregate outstanding obligation of $879,163 (the “Settlement Amount”), representing all principal and accrued interest owed under two promissory notes previously issued by the Company: (i) a 9.75% promissory note in the principal amount of $400,000 issued on October 15, 2024 to Blackwolf Venture Group LLC, a Florida limited liability company controlled by Wolf, and (ii) a 9.75% promissory note in the principal amount of $500,000 issued on October 16, 2024 to Wolf (collectively, the “Wolf Notes”). Both Wolf Notes had matured on November 5, 2025 and were in default as of the date of the Wolf Settlement Agreement. The Settlement Amount will be satisfied through net proceeds from Wolf’s sales of Helio common stock in accordance with the following leak-out terms: Wolf may sell up to the greater of (a) 4,000 shares on any trading day on which aggregate daily trading volume equals or exceeds 20,000 shares, or (b) 12% of aggregate daily trading volume on any such trading day, with no single sale block exceeding 2,000 shares without the Company’s prior written consent. Under the Wolf Settlement Agreement, Wolf’s daily sale limit was to increase to 25% of aggregate daily trading volume upon the earlier of (i) the uplisting of the Company’s common stock to the Nasdaq Stock Market or the New York Stock Exchange, or (ii) July 5, 2026; that date has passed and, as of the date of this prospectus, Wolf’s daily sale limit is 25% of aggregate daily trading volume. Wolf will provide brokerage account statements twice monthly, with net proceeds applied to reduce the Settlement Amount. The Company agreed to authorize ClearTrust, LLC to remove the restrictive legend on 45,000 shares of Helio common stock held in book entry for Wolf’s benefit no later than 9:30 A.M. Eastern Time on April 28, 2026. In addition, Wolf is responsible for seeking the cooperation of Joseph Pitman to transfer 55,000 shares of Helio common stock held by Pitman to Wolf, subject to the same leak-out terms; the Company agreed to provide a Rule 144 opinion letter with respect to those shares following the transfer. If Fidelity Investments declines to accept or process Wolf’s shares, the Company is required to secure an alternate brokerage firm within seven business days; failure to do so renders the Wolf Settlement Agreement null and void. No new shares were issued by the Company in connection with the Wolf Settlement Agreement.

Series A Preferred Stock

On April 17, 2026, the Company designated 1,500,000 shares of Series A Convertible Preferred Stock. On February 6, 2026, the Company sold 15 shares of Series A Convertible Preferred Stock for an aggregate purchase price of $15,000, which were simultaneously converted into 12,510 shares of common stock. The Company subsequently sold 175,000 shares of Series A Convertible Preferred Stock for $175,000 pursuant to a Series A Preferred Stock Purchase Agreement dated April 17, 2026 and funded on or about May 5, 2026, 200,000 shares for $200,000 on June 16, 2026, and 200,000 shares for $200,000 on July 16, 2026. As of July 31, 2026, 575,000 shares of Series A Convertible Preferred Stock were issued and outstanding. Each share of Series A Convertible Preferred Stock has a stated value of $1.00 per share, carries a cumulative annual dividend of 10% of the stated value (increasing to 22% upon an event of default), and, beginning 180 days after issuance, is convertible into shares of common stock at a variable conversion price equal to 65% of the lowest trading price of the common stock during the ten trading days preceding conversion, subject to a 4.99% beneficial ownership limitation that may not be waived.

Series B Preferred Stock

On May 29, 2026, the Company sold 177,500 shares of newly designated Series B Convertible Preferred Stock to Efrat Investments LLC for an aggregate purchase price of $159,750 (reflecting a purchase price of $0.90 per share, a 10% original issue discount to the stated value of $1.00 per share), and on July 27, 2026, the Company sold an additional 177,500 shares of Series B Convertible Preferred Stock to SilverCrest Hybrid Capital LLC for an aggregate purchase price of $159,750 ($0.90 per share). As of July 31, 2026, 355,000 shares of Series B Convertible Preferred Stock were issued and outstanding. Each share of Series B Preferred Stock is convertible into shares of common stock, subject to a 4.99% beneficial ownership limitation.

Series C Preferred Stock

On June 19, 2026, the Company sold 200,000 shares of newly designated Series C Convertible Preferred Stock to Auctus Fund, LLC for an aggregate purchase price of $200,000 (a stated value of $1.00 per share). The Series C Preferred Stock carries a cumulative annual dividend of 10% of the stated value (increasing to 22% upon an event of default) and, beginning 180 days after issuance, is convertible into shares of common stock at a variable conversion price equal to 65% of the lowest trading price of the common stock during the ten trading days preceding conversion, subject to a 4.99% beneficial ownership limitation that may not be waived. The Series C Preferred Stock ranks senior to the common stock, but junior to the Company’s other outstanding preferred stock and all existing and future indebtedness, with respect to dividends and distributions upon liquidation.

Share Repurchase Program

On July 2, 2026, the Board of Directors authorized the Company to repurchase up to 250,000 shares of its common stock from time to time through September 30, 2026, and ratified 9,477 shares repurchased prior to adoption of the program. The repurchase program was not publicly announced. Pursuant to the program, the Company has repurchased an aggregate of 9,376  shares of common stock (as adjusted for the 1-for-5 Reverse Stock Split) in open-market transactions for an aggregate purchase price of approximately $49,994.31.

Additional Post-Year-End Financings

Following the fiscal year ended October 31, 2025, the Company entered into additional financing transactions, including the issuance of promissory and convertible notes for aggregate gross proceeds of approximately $300,000 on January 12–14, 2026, and approximately $760,272 in aggregate principal amount (net proceeds approximately $667,000) in February 2026 pursuant to multiple securities purchase agreements. These transactions are described in greater detail under “Certain Relationships and Related Party Transactions” and “Management’s Discussion and Analysis — Liquidity and Capital Resources.”

In a private placement conducted from April 9, 2026 through May 8, 2026, the Company sold an aggregate of 93,276 shares of its common stock (on a post-split basis) to 53 purchasers, each of whom represented that it was an accredited investor, for aggregate gross proceeds of $326,446.42. No sales commissions or finders’ fees were paid in connection with this offering. These securities were offered and sold in reliance upon the exemptions from registration provided by Section 4(a)(2) of the Securities Act and Rule 506(b) of Regulation D.

Reverse Stock Split

On May 9, 2026, the Board of Directors approved and recommended the Reverse Stock Split at a ratio within the range of 1-for-1.25 to 1-for-5, and on May 11, 2026, holders of approximately 64.70% of the outstanding shares of Common Stock approved the Reverse Stock Split and the related amendment to the Company’s Articles of Incorporation by written consent in lieu of a special meeting pursuant to Section 607.0704 of the Florida Business Corporation Act. On July 7, 2026, the Board of Directors determined to effect the Reverse Stock Split at a ratio of 1-for-5. The Company filed an Information Statement on Schedule 14C with the SEC and distributed it to shareholders, and observed the required 20-calendar-day waiting period under Regulation 14C. The Reverse Stock Split became effective on July 20, 2026, the effective date specified in the Articles of Amendment to the Company’s Articles of Incorporation filed with the Florida Department of State. All share counts and per-share figures in this prospectus give effect to the 1-for-5 Reverse Stock Split and are presented on a post-split basis. See “The Offering - Reverse Stock Split.”

THE OFFERING

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider each of the following risks, together with all other information set forth in this prospectus, including the consolidated financial statements and the related notes, before making a decision to buy our securities. If any of the following risks actually occur, our business could be harmed. The risks and uncertainties described herein are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

Risks Relating to Our Financial Condition

The Company may need additional capital, which may not be available.

The Company will require funds in excess of its existing cash resources to fund operating deficits, develop new products or services, establish and expand its marketing capabilities, and finance general and administrative activities. As of July 31, 2026, the Company had cash and cash equivalents of approximately $520,504, and the audit reports on its financial statements for the fiscal years ended October 31, 2025 and 2024 each included an explanatory paragraph expressing substantial doubt about the Company’s ability to continue as a going concern. As of the date of this prospectus, all notes previously in default have been resolved and are now current. Due to the Company’s current financial condition and general market conditions, it is possible that the Company will be unable to obtain additional funding as and when it needs it. If the Company is unable to obtain additional funding, it may not be able to repay debts when they are due and payable. If the Company is able to obtain capital, it may be on unfavorable terms or terms which excessively dilute then-existing equity holders. If the Company is unable to obtain additional funding as and when needed, it could be forced to delay its development, marketing, and expansion efforts and, if it continues to experience losses, potentially cease operations.

We have a history of promissory note defaults, and future defaults may occur.

As of the date of this prospectus, all promissory notes previously in default have been resolved and are now current. As described in “Recent Developments — Wolf Settlement Agreement,” the two largest defaulted notes (original principal amounts of $400,000 and $500,000, respectively) were resolved pursuant to the Wolf Settlement Agreement dated April 27, 2026. The Amended and Restated Secured Promissory Note dated October 15, 2024, in the original principal amount of $250,000 (the “Cole Note”), which had been in default following its November 5, 2025 maturity, has been resolved and is now current. Three additional notes (original principal amounts of $50,000, $150,000, and $50,000, respectively) previously in default following receipt of notices in February 2026 have also been resolved. A convertible promissory note originally in the principal amount of $250,000 (as amended to $500,000), which was in default as of April 30, 2026, was resolved on June 13, 2026 pursuant to an agreement whereby the holder agreed not to pursue any default provisions in exchange for a $20,000 initial payment, $15,000 monthly installments beginning July 15, 2026, and the transfer of 6,600 shares of common stock by Gregory T. Delory from shares personally owned by him (rather than an issuance by the Company). While all existing defaults have been resolved, the Company’s liquidity position remains constrained and there can be no assurance that new defaults will not arise in the future.

We have substantial doubt about our ability to continue as a going concern, which may adversely affect our ability to raise capital and operate our business.

Our independent registered public accounting firm’s audit reports on our consolidated financial statements for the fiscal years ended October 31, 2025 and October 31, 2024 each included an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern is dependent upon our ability to raise additional capital through this offering and other financings and to achieve profitability. There can be no assurance that we will be able to do so. If we are unable to raise sufficient capital or achieve profitability, we may be forced to curtail our operations, liquidate our assets, or cease operations entirely, which would result in a complete loss of your investment.

We have identified material weaknesses in our internal control over financial reporting, and if we fail to remediate them, our ability to accurately and timely report our financial results may be impaired.

In connection with our Quarterly Report on Form 10-Q for the quarter ended July 31, 2026, management concluded that our disclosure controls and procedures were not effective as of July 31, 2026 due to material weaknesses in our internal control over financial reporting, including a lack of segregation of duties within our finance and accounting function and an insufficient number of qualified accounting personnel with knowledge of U.S. GAAP and SEC reporting requirements. If we are unable to remediate these material weaknesses, or if we identify additional material weaknesses, we may be unable to accurately or timely report our financial condition or results of operations, which could cause investors to lose confidence in our reported financial information and adversely affect the market price of our common stock.

We have a history of net losses and an accumulated deficit, and we expect to continue to incur losses.

We have incurred net losses in each of our fiscal years ended October 31, 2025 ($4,030,471) and October 31, 2024 ($1,862,683), and we incurred a net loss of $6,851,175 for the nine months ended July 31, 2026. As of July 31, 2026, we had a total shareholders’ deficit of approximately $(2,757,273). We expect to continue to incur losses as we invest in our operations and seek to grow our business.

We have outstanding indebtedness and we may be unable to service or repay our obligations.

As of the date of this prospectus, we have significant outstanding indebtedness, including multiple promissory notes and convertible notes. All notes previously in default have been resolved as of the date of this prospectus. The aggregate outstanding obligation of $879,163 under two previously defaulted secured promissory notes (the “Wolf Notes”) was settled in full pursuant to the Wolf Settlement Agreement dated April 27, 2026, pursuant to which a former officer of the Company personally transferred 100,000 shares of Helio common stock to the noteholders; the Company recognized this as a capital transaction during fiscal year 2026. The Cole Note, which matured November 5, 2025, has been resolved and is now current. A convertible promissory note originally in the principal amount of $250,000 (amended to $500,000) that was previously in default was resolved on June 13, 2026. If we are unable to service our remaining outstanding indebtedness when due, such actions could have a material adverse effect on our business, financial condition, and results of operations.

Our cash position is limited and we will require additional financing to fund our operations and growth.

As of July 31, 2026, we had cash and cash equivalents of approximately $520,504. We do not believe that our current cash resources are sufficient to fund our operations beyond the near term. We are highly dependent on the proceeds of this offering and future financing activities to fund our operations. If we cannot raise sufficient capital, we may be forced to reduce or cease operations.

Risks Relating to Our Business, Industry, and Strategy

Our business focuses exclusively on the space industry and therefore is not diversified.

During a prolonged period of significant market disruption in the space industry, such as the adverse impact the COVID-19 pandemic had and other macroeconomic factors such as when recessions occur, our business may be disproportionately impacted compared to companies that are more diversified in the industries they serve. A more diversified company with significant sales and earnings derived from outside the space industry may be able to recover more quickly from significant market disruptions.

A significant portion of our revenue is derived from U.S. government contracts, which are subject to termination, reduction, and budgetary uncertainty.

Because a significant percentage of our revenue (approximately 70% for the fiscal year ended October 31, 2025, approximately 92% for the nine months ended July 31, 2026, and approximately 82% for the three months ended July 31, 2026) is derived either directly or indirectly from contracts with the U.S. government, including through NASA, changes in federal government budgetary priorities could directly affect our financial performance.

According to the Fiscal Y 2027 President’s Budget released on April 2026, the White House released its proposed budget for FY 2027, which included an overall reduction of approximately 23% to NASA’s budget from current enacted levels, including proposed cuts of approximately $3.4 billion to NASA’s science programs, which have historically represented a significant source of revenue for the Company. While Congress declined to enact the proposed cuts to NASA science programs for FY 2026 and restored NASA’s budget to near prior-year levels, there can be no assurance that Congress will take similar action with respect to the FY 2027 budget or future fiscal years. Additionally, while Heliospace participates in lunar exploration programs that have to date received continued government support, the current political environment introduces significant uncertainty regarding future NASA funding levels that cannot be predicted with reasonable certainty. Significant budget cuts to NASA science programs, if enacted for FY 2027 or beyond, could have a material adverse effect on the Company’s revenue and results of operations.

We have a history of promissory note defaults and may be subject to legal proceedings in the future.

As of the date of this prospectus, the Company is not in default under any outstanding promissory note. As described elsewhere in this prospectus, all notes previously in default, including the Cole Note, the $400,000 and $500,000 notes resolved pursuant to the Wolf Settlement Agreement, and a convertible promissory note originally in the principal amount of $250,000 (as amended to $500,000) resolved pursuant to a June 13, 2026 payment and equity arrangement, have been fully resolved and are now current. See also “Recent Developments - Note Defaults” and “Recent Developments - Wolf Settlement Agreement.”

Our limited operating history and declining revenues make it difficult to evaluate our future prospects.

Our limited operating history makes it difficult to evaluate our future prospects and the risks and challenges we may encounter. We have not demonstrated a sustained ability to generate predictable revenue from our products and services. Consequently, any assessment you make about our current business or future success or viability may not be as accurate as it could be if we had a longer operating history. Further, our limited financial track record is of limited reference value for your assessment of our business and future prospects.

Risks and challenges we have faced or expect to face include our ability to:

We have experienced significant and continuing revenue declines that make it difficult to forecast our future results. Revenue for the fiscal year ended October 31, 2025 decreased by approximately 44% to $3,875,793 from $6,891,223 for the fiscal year ended October 31, 2024, which itself reflected a decline of approximately 25% from $9,209,329 in fiscal year 2023. Contributing factors to the FY2025 decline include continuing budget cuts to NASA programs enacted by the current administration, combined with the extended government shutdown, which reduced the overall volume of work available to us. During the fiscal year ended October 31, 2025, we serviced eleven customers-two direct government customers, four private or commercial customers, three nonprofit customers for whom we manufactured products as a subcontractor to government customers, and two commercial customers whose source of funds was private investment-compared to thirteen customers during fiscal year 2024. This contraction in our customer base, combined with continued dependence on government-funded programs, increases our vulnerability to further budget-driven disruptions. For the nine months ended July 31, 2026, revenue was $11,543,492, compared to $33,384,423 for the nine months ended July 31, 2025, a decline of approximately 54%, and for the three months ended July 31, 2026, revenue was $590,626, compared to $784,587 for the three months ended July 31, 2025, a decline of approximately 25%. During the nine months ended July 31, 2026, we serviced only six customers, compared to eleven customers in the comparable prior-year period. We may continue to incur losses in future periods. While we are actively working to expand into new commercial markets and have identified specific opportunities in the commercial and defense sectors, the primary challenge is the time and resources required to successfully transition and grow our business beyond government-funded programs. There can be no assurance that such efforts will succeed or will be completed on a timeline sufficient to offset any continued reduction in government-funded revenues.

If we fail to address the risks and difficulties that we face, including those associated with the challenges listed above as well as those described elsewhere in this “Risk Factors” section, our business, financial condition, and results of operations could be adversely affected. In addition, because we have limited historical financial data and operate in a rapidly evolving market, any predictions about our future revenue and expenses may not be as accurate as they would be if we had a longer operating history or operated in a more developed market. We have encountered in the past, and will encounter in the future, risks and uncertainties frequently experienced by growing companies with limited operating histories in rapidly changing industries. If our assumptions regarding these risks and uncertainties, which we use to plan and operate our business, are incorrect or change or if we do not address these risks successfully, our results of operations could differ materially from our expectations and our business, financial condition, and results of operations could be adversely affected.

The Company may not be able to manage its potential growth.

For the Company to succeed, it needs to experience significant expansion. There can be no assurance that it will achieve this expansion. This expansion, if accomplished, may place a significant strain on the Company’s management, operational and financial resources. To manage any material growth, the Company will be required to implement operational and financial systems, procedures and controls. It also will be required to expand its finance, administrative and operations staff. There can be no assurance that the Company’s current and planned personnel, systems, procedures and controls will be adequate to support its future operations at any increased level. The Company’s failure to manage growth effectively could have a material adverse effect on its business, results of operations, and financial condition.

The Company’s growth relies on market acceptance.

While the Company believes that there will be significant customer demand for its products and services, there is no assurance that there will be broad market acceptance of the Company’s offerings. A substantial portion of the Company’s revenue has historically been derived from U.S. government sources, and proposed federal budget cuts - including proposed reductions to NASA’s Science Mission Directorate under recent White House budget proposals for FY 2026 and FY 2027 - could materially reduce demand for the Company’s core products and services. Although the Company is actively working to increase the percentage of revenue from private and commercial sources and to expand its offerings to defense agencies, there can be no assurance that these efforts will succeed or will fully offset any reduction in government spending. In such event, there may be a material adverse effect on the Company’s results of operations and financial condition and the Company may not be able to achieve its business goals.

Our operating results may continue to be adversely affected as a result of unfavorable market, economic, social and political conditions.

An unstable global economic, social, and political environment may have a negative impact on demand for our services, our business, and our operations, including the U.S. economic environment. The economic, social, and political environment has or may negatively impact, among other things:

In addition, broader fiscal challenges at the federal level-such as the rising national debt, persistent budget deficits, and the risk of government shutdowns or extended continuing resolutions-could result in delays to contract funding or payments, reduced availability of new program opportunities, and increased uncertainty in our long-term planning. These macroeconomic pressures may also negatively affect private sector customers that rely on or benefit from government-funded space and research initiatives.

Our success depends on the effectiveness and continuity of our senior management team and key personnel, and any difficulty attracting, retaining, or transitioning leadership could adversely affect our business.

The Company has recently strengthened its senior management team with experienced leadership across key executive functions, including the appointment of a new Chief Executive Officer, Chief Financial Officer, and Chief Technology Officer, and has made intentional changes to its Board composition. While these changes are designed to enhance the Company’s execution and growth capabilities, any period of leadership change involves inherent risks - including potential continuity challenges in customer relationships, ongoing project execution, and strategic initiatives - regardless of the purpose or circumstances of such changes. There can be no assurance that the Company’s current leadership team will achieve the Company’s strategic objectives on the expected timeline, or that any transition-related challenges will not adversely affect our business, results of operations, and financial condition.

Our success depends heavily on our executive officers and highly trained employees, and difficulty hiring or retaining similar employees could adversely affect our business.

We depend on an educated and trained workforce. Historically, substantial competition for skilled personnel in the aerospace industry has existed, and we could be adversely affected by a shortage of skilled employees. We may not be able to fill new positions or vacancies created by expansion or turnover or attract and retain qualified personnel. We may not be able to continue to hire, train, and retain qualified employees at current wage rates since we operate in a competitive labor market and currently significant inflationary and other pressures on wages exist.

Our future ability to execute our business plan depends upon the continued service of our Chief Executive Officer, Chief Technology Officer, and Chief Engineer. If we lost the services of one or more of our key personnel, or if one or more of our executive officers or employees joined a competitor or otherwise competed with us, our business may be adversely affected. We cannot assure that we will be able to retain or replace our key personnel.

In addition, our success depends in part on our ability to attract and motivate our senior management and key employees. Achieving this objective may be difficult due to a variety of factors, including fluctuations in economic and industry conditions, competitors’ hiring practices and the effectiveness of our compensation programs. Competition for qualified personnel can be intense. If we are unable to effectively provide for the succession of key personnel, senior management, and our executive officers, our business, results of operations, cash flows, and financial condition may be adversely affected.

Competition could cause downward pressure on prices, fewer customer orders, reduced margins, and loss of market share.

Competition within our product offerings, across individual products and applications, ranges from divisions of large corporations that may be better capitalized and have more industry or management experience, to small, privately held companies that may be more innovative or agile than we are. Any of these factors could negatively impact our ability to take advantage of new business opportunities and expand into new commercial markets or cause us to lose market share.

The market for our products and services is uncertain and may not grow as expected.

The market for our products and services has not been fully established as the commercialization of space is a relatively new development and is rapidly evolving. Our estimates for the total addressable markets for our products and services are based on a number of factors, including third-party estimates or variables that are out of our control including assumed prices at which we can offer our products and services, our ability to leverage our current manufacturing and operational processes, and general market conditions. While we believe our assumptions and the data underlying our estimates of the total addressable markets for our products and services are reasonable, these assumptions and estimates may not be correct and the conditions supporting our assumptions or estimates may change at any time, thereby reducing the predictive accuracy of these underlying factors. As a result, our estimates of the annual total addressable markets, as well as the expected growth rate for the total addressable market for those products and services, may prove to be incorrect, which could have a material adverse effect on our business, financial condition, and results of operations. In addition, if our revenue-generating projects are terminated or delayed and we are unable to replace them with new projects on similar terms, or at all, or if revenue grows slower than we anticipate, we may not be able to achieve profitability and our business, financial condition, and results of operations may be materially and adversely affected.

If we are unable to adapt to technological change, demand for our products may be reduced.

The market for our products and services is characterized by rapid change and technological developments. Failure to respond in a timely and cost-effective way to these technological developments would result in serious harm to our business and operating results. The technologies related to our products have undergone and, in the future, may undergo, significant changes. As a result, our continued growth, and the success of our business strategy will depend, in part, on our ability to be both innovative and agile in designing, developing, manufacturing, assembling, testing, marketing and supporting new products and enhancements and we may not be able to do so successfully, if at all, or on a timely, cost effective, or repeatable basis. If we cannot in a timely and cost-effective manner satisfy changing customer needs and respond to changing industry cycles, it may adversely affect our business, financial condition, and results of operations. Our competitors may develop technologies and products that are more effective than those we develop or that render our technology and products obsolete or noncompetitive. Furthermore, our products could become unmarketable if new industry standards emerge. We may need to modify our products significantly in the future to remain competitive and new products we introduce may not be accepted by our customers.

We believe that, in order to remain competitive in the future, we will need to continue to invest significant financial resources to develop new products, services and solutions, including through internal research and development, acquisitions and joint ventures or other teaming arrangements. These expenditures could divert our attention and resources from other projects, and we cannot be sure that these expenditures will ultimately lead to the timely development of new products, services and solutions or identification of and expansion into new markets. Due to the design complexity of our products, we may, in the future, experience delays in completing the development and introduction of new products. Any delays could result in increased costs of development or deflect resources from other projects. In addition, there can be no assurance that the market for our products will develop or continue to expand or that we will be successful in newly identified markets as we currently anticipate. If we are unable to achieve sustained growth, we may be unable to execute our business strategy, expand our business or fund other liquidity needs and our business prospects, financial condition, and results of operations could be materially and adversely affected. Furthermore, we cannot be sure that our competitors will not develop competing technologies that gain market acceptance in advance of our products.

Federal contracting is subject to significant regulation, and non-compliance could subject us to fines and penalties.

Like all government contractors, we are subject to risks associated with this contracting. These risks include the potential for substantial civil and criminal fines and penalties. These fines and penalties could be imposed for failing to follow procurement integrity and bidding rules, employing improper billing practices or otherwise failing to follow cost accounting standards, receiving or paying kickbacks or filing false claims. We have been, and expect to continue to be, subjected to audits and investigations by government agencies. The failure to comply with the terms of our government contracts could harm our business reputation, which could significantly reduce our sales and earnings. It could also result in our suspension or debarment from future government contracts, which would adversely affect our business, financial condition, results of operations, and cash flows. Moreover, U.S. Government purchasing regulations contain a number of operational requirements that apply to entities engaged in government contracting. Failure to comply with such government contracting requirements could result in civil and criminal penalties that could have a material adverse effect on the Company’s results of operations.

The U.S. government may modify, curtail or terminate one or more of our contracts, and failure to comply with contract terms or applicable laws and regulations in relation to our U.S. government contracts could expose us to penalties or other adverse consequences.

The U.S. government contracting party may modify, curtail or terminate its contracts with us, without prior notice and either at its convenience or for default based on performance. In addition, funding pursuant to our U.S. government contracts may be reduced or withheld as part of the U.S. Congressional appropriations process. Any loss or anticipated loss or reduction of expected funding and/or modification, curtailment, or termination of one or more of our U.S. government contracts could have a material adverse effect on our earnings, cash flow and/or financial position, as well as our access to government testing facilities and/or our ability to secure pre-certification operating experience and/or revenues.

The U.S. government may also audit and investigate contractors and subcontractors; claim rights, including intellectual property rights, in products and data developed under certain contracts; suspend or debar contractors from doing business with the government or a specific government agency; impose U.S. manufacturing requirements for products that embody inventions conceived or first reduced to practice under such agreements; and control or prohibit the export of products.

If the government discovers improper or illegal activities or contractual non-compliance (including improper billing), we may be subject to various civil and criminal penalties and administrative sanctions, which may include termination of contracts, forfeiture of profits, suspension of payments, fines and suspensions or debarment from doing business with the government. Also, the qui tam provisions of the federal and various state civil False Claims Acts authorize a private person to file civil actions on behalf of the federal and state governments and retain a share of any recovery which can include treble damages and civil penalties. Further, the negative publicity that could arise from any such penalties, sanctions or findings could have an adverse effect on our reputation and reduce our ability to compete for new contracts with both government and commercial clients.

Technology failures or cyber security breaches could have an adverse effect on our business.

We rely on information technology systems to process, transmit, store, and protect electronic information. For example, a significant portion of the communications between our personnel, customers, suppliers, and vendors depends on information technology and we rely on access to such information systems for our operations. Additionally, we rely on third-party service vendors to execute certain business processes and maintain certain information technology systems and infrastructure. The security measures in place may not prevent disruptions, failures, computer viruses or other malicious codes, malware or ransomware incidents, unauthorized access attempts, theft of intellectual property, trade secrets, or other corporate assets, denial of service attacks, phishing, hacking by common hackers, criminal groups or nation-state organizations or social activist (“hacktivist”) organizations and other cyber-attacks or other privacy or security breaches in the information technology, phone systems, or other systems (whether due to third-party action, bugs or vulnerabilities, physical break-ins, employee error, malfeasance or otherwise) of the Company, our customers or third parties, which could adversely affect our communications and business operations. Further, events such as natural disasters, fires, power outages, systems failures, telecommunications failures, employee error or malfeasance or other catastrophic events could similarly cause interruptions, disruptions or shutdowns, or exacerbate the risk of the failures described above. These risks may be increased as more employees work from home. We may not have the resources or technical sophistication to anticipate, prevent or detect rapidly evolving types of cyber-attacks and other security risks. Attacks may be targeted at us, our customers, suppliers or vendors, or others who have entrusted us with information. To date, the Company has not experienced any material impact to the business or operations resulting from information or cybersecurity attacks. However, because of the frequently changing attack techniques, along with the increased volume, persistence and sophistication of the attacks, the Company may be adversely impacted in the future. Because such techniques change frequently or may be designed to remain dormant until a predetermined event and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement sufficient control measures to defend against these techniques. Once a security incident is identified, we may be unable to remediate or otherwise respond to such an incident in a timely manner. While the Company has policies and procedures in place, including system monitoring and data back-up processes to prevent or mitigate the effects of these potential disruptions or breaches, security breaches and other disruptions to information technology systems could interfere with our operations. Any failure to maintain, or disruption to, our information technology systems, whether as a result of cybersecurity attacks or otherwise, could damage our reputation, subject the Company to legal claims and proceedings or remedial actions, create risks of violations of data privacy laws and regulations, and cause us to incur substantial additional costs. Existing or emerging threats may have an adverse impact on our systems or communications networks and, further, technological enhancements to prevent business interruptions could require increased spending. Furthermore, security breaches pose a risk to confidential data and intellectual property, which could result in damage to our competitiveness and reputation. The costs, potential monetary damages, and operational consequences of responding to cyber incidents and implementing remediation measures may not be covered by any insurance that we may carry from time to time. We cannot predict the degree of any impact that increased monitoring, assessing, or reporting of cybersecurity matters would have on operations, financial conditions and results.

From time to time, we may implement new technology systems or replace and/or upgrade our current information technology systems. These upgrades or replacements may not improve our productivity to the levels anticipated and may subject us to inherent costs and risks associated with implementing, replacing, and updating these systems, including potential disruption of our internal control structure, substantial capital expenditures, demands on management time, and other risks of delays or difficulties in transitioning to new systems or of integrating new systems into other existing systems.

We rely on direct electronic interfaces with some of our key customers, suppliers, and vendors. Cyber security breaches or technology failures at our customers could result in changes to timing and volume of orders. Additionally cyber security breaches or technology failures at our suppliers or vendors could impact the timing or availability of key materials that could negatively impact our ability to deliver products to our customers.

Our operations depend on our manufacturing facilities, which are subject to physical and other risks.

Our operations and those of our customers and suppliers have been and may again be subject to natural disasters, climate change-related events, pandemics, or other business disruptions, which could seriously harm our results of operation and increase our costs and expenses. Some of our manufacturing facilities are located in regions that may experience earthquakes or be impacted by severe weather events, such as increased storm frequency or severity in the Atlantic and fires in hotter and drier climates. These could result in potential damage to our physical assets as well as disruptions in manufacturing activities. Some of our manufacturing facilities are located in areas that may be at risk due to rising sea levels. Moreover, some of our manufacturing facilities are located in areas that could experience decreased access to water due to climate issues, including, but not limited to, our facilities in California.

We are also vulnerable to damage from other types of disasters, including power loss, fire, explosions, floods, communications failures, terrorist attacks, and similar events. Disruptions could also occur due to health-related outbreaks and crises, cyber-attacks, computer or equipment malfunction, accidental or intentional, operator error, or process failures. Should insurance or other risk transfer mechanisms, such as our existing disaster recovery and business continuity plans, be insufficient to recover all costs, we could experience a material adverse effect on our business, results of operations, financial position, and cash flows.

We depend on third-party fabricators and component suppliers to manufacture our hardware, and any disruption in their operations or supply chains could adversely affect our ability to deliver products to our customers.

Heliospace outsources the fabrication of hardware components to third-party manufacturers after translating designs to detailed drawings. We do not maintain an inventory of raw materials or finished goods, and the value we add is primarily through design, engineering, assembly, and testing. While we seek to maintain multiple qualified sources for critical components and conduct quality assurance reviews of incoming materials, we are nonetheless dependent on the performance, capacity, and financial stability of our vendors. Disruptions in third-party fabrication, whether due to supply chain interruptions, vendor financial difficulties, natural disasters, geopolitical events, or quality failures, could delay our deliveries, increase our costs, or cause us to fail to meet contractual milestones, any of which could harm our customer relationships and financial results. Some of the components used in our hardware incorporate relatively scarce raw materials. Although our third-party fabricators have historically been able to procure such materials, we cannot guarantee they will continue to do so in the future. Our failure to maintain an adequate supply of components and materials from third-party fabricators could have a material adverse effect on our business, financial condition, and results of operations.

Our revenue is highly concentrated among a small number of customers, and the loss of, or significant reduction in business from, any key customer could materially adversely affect our financial results.

A significant percentage of our revenue has historically been derived from a small number of customers. Approximately 70% and 75% of our revenue for the fiscal years ended October 31, 2025 and October 31, 2024, respectively, was derived, directly or indirectly, from U.S. government sources, either as a prime contractor or as a subcontractor, and in each such period, more than 67% of our revenue was attributable to three customers. For the nine months ended July 31, 2026, approximately 92% of our revenue was derived from government sources, serviced by only six customers. One prime contractor customer under an indefinite delivery/indefinite quantity (“IDIQ”) contract with NASA accounted for approximately 31% of our revenue in the fiscal year ended October 31, 2025. Additionally, four customers accounted for approximately 94% of our outstanding accounts receivable as of July 31, 2026. Our customers generally have no obligation to renew, upgrade, or expand their agreements with us after the terms of their existing agreements expire. In addition, many of our customer contracts permit the customer to terminate their contracts with us for convenience, for default, or for other reasons specified in our contracts, with notice periods of varying lengths. If one or more of our customers terminate their relationships with us, fail to renew or extend their contracts, significantly reduce the scope of work, or if funding for programs that support our contracts is reduced or eliminated, our revenue could decline substantially and our results of operations would be adversely affected. This adverse impact would be more pronounced for customers that represent a material portion of our revenue or accounts receivable. Our efforts to diversify our customer base and reduce our dependence on government-funded programs may not succeed on a timeline sufficient to offset any such loss, which could have a material adverse effect on our business, financial condition, and results of operations.

Pricing pressures from customers could reduce the demand and/or price for our products and services.

From time to time, we may face pricing pressures from our customers due to factors beyond our control, including liquidity constraints and adverse macroeconomic conditions. If we are unable to respond to pricing pressures or otherwise successfully compete for new business, our revenue growth and operating margins may decline.

If we fail to establish and maintain important relationships with government agencies and prime contractors, our ability to successfully maintain and develop new business could be materially adversely affected.

Our reputation and relationship with the U.S. government are key factors in maintaining and developing new business opportunities. Negative press reports regarding conflicts of interest, poor contract performance, employee misconduct, information security breaches or other aspects of our business, regardless of accuracy, could harm our reputation.

We have contracts with the U.S. government related to classified programs, which may limit investor insight into portions of our business.

We derive a portion of our revenues from programs with the U.S. government and its agencies that are subject to security restrictions (e.g., contracts involving classified information and classified programs), which preclude the dissemination of information and technology that is classified for national security purposes under applicable law and regulation. In general, access to classified information, technology, facilities, or programs requires appropriate personnel security clearances, is subject to additional contract oversight and potential liability, and also requires appropriate facility security clearances and other specialized infrastructure. In the event of a security incident involving classified information, technology, facilities, programs, or personnel holding clearances, we may be subject to legal, financial, operational, and reputational harm. We are limited in our ability to provide information about these classified programs, their risks or any disputes or claims relating to such programs. As a result, investors have less insight into our classified business or our business overall. However, historically the business risks associated with our work on classified programs have not differed materially from those of our other government contracts.

Risks Relating to the Reverse Stock Split

Our reverse stock split may not achieve the intended benefits and could have adverse effects.

We have effected a reverse stock split of our Common Stock at a ratio of 1-for-5. On May 9, 2026, the Board of Directors approved the Reverse Stock Split within the range of 1-for-1.25 to 1-for-5, and on May 11, 2026, holders of approximately 64.70% of the outstanding shares of Common Stock approved the Reverse Stock Split and the related amendment to the Articles of Incorporation by written consent. On July 7, 2026, the Board determined the final ratio of 1-for-5. Prior to effecting the Reverse Stock Split, the Company filed and distributed to shareholders an Information Statement on Schedule 14C and observed the required 20-calendar-day waiting period under Regulation 14C. The Reverse Stock Split became effective on July 20, 2026, the effective date specified in the Articles of Amendment filed with the Florida Department of State. While we expect the Reverse Stock Split to increase the per-share price of our Common Stock and facilitate our Nasdaq listing application, we cannot guarantee that the per-share price will increase proportionately or that it will remain at a level sufficient for the Nasdaq Capital Market to approve our listing application or to maintain a listing following the Reverse Stock Split. In addition, reverse stock splits often lead to short-term price volatility. Additionally, following the Reverse Stock Split, the number of shares reserved for issuance under our 2025 Equity Incentive Plan was reduced proportionately and was subsequently further reduced to 300,000 shares by amendment to the plan, which also eliminated the plan’s automatic annual increase, which could limit our ability to attract and retain employees through equity compensation.

Following the reverse stock split, our stock price may fail to satisfy the Nasdaq minimum bid price requirement.

Even after the reverse stock split, there is no guarantee that the per-share market price of our Common Stock will meet the minimum bid price requirement of the Nasdaq Capital Market ($4.00 per share at time of listing) or that it will remain at that level following our listing. If our stock price declines below the applicable minimum bid price, we may be subject to delisting procedures.

Risks Relating to Our Common Stock and This Offering

Our application for listing on the Nasdaq Capital Market has been submitted but may not be approved, in which case we will not consummate the primary offering.

Consummation of the primary offering described herein is conditioned upon our Common Stock being approved for listing on the Nasdaq Capital Market. We have submitted a listing application; however, there can be no assurance that our application will be approved or that we will be able to satisfy all applicable listing requirements. If our application is not approved or we are unable to satisfy the listing requirements, we will not consummate the primary offering.

As the offering price is substantially higher than our net tangible book value per share, you will experience immediate and substantial dilution.

If you purchase Common Stock in this offering, you will pay more for your shares of Common Stock than the amount paid by our existing stockholders for their shares on a per share basis. As a result, you will experience immediate and substantial dilution in net tangible book value per share in relation to the price that you paid for your shares. We expect the dilution as a result of the offering to be $3.84 per share to new investors purchasing our shares of Common Stock in this offering, based on an assumed initial offering price $4.50, which is the midpoint of the price range set forth on the cover page of this prospectus. In addition, you will experience further dilution to the extent that our shares are issued upon the exercise of any warrants, including the Representative Warrants or exercise of stock options under any stock incentive plans. See “Dilution” for a more complete description of how the value of your investment in our shares will be diluted upon completion of this offering.

You may experience significant dilution from the conversion of outstanding convertible instruments.

In addition to dilution from the primary offering, investors will experience significant additional dilution from:

The cumulative effect of all of the foregoing could result in substantial dilution to investors purchasing shares in this offering. The actual amount of dilution will depend on, among other things, the reverse stock split ratio, the market price of our Common Stock at the time of conversion or exercise of the applicable instruments, and the number of shares sold in this offering. For a more detailed discussion of the dilution you will experience as a result of this offering, see “Dilution.”

Future sales or conversion of our Common Stock or other securities could depress the market price of our Common Stock.

Future sales in the public market of shares of our Common Stock, or securities convertible into or exchangeable or exercisable for shares of Common Stock, or the perception by the market that these sales could occur, could lower the market price of our Common Stock and make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Sources of potential future sales include: (i) shares sold in the primary offering; (ii) the 52,640 shares issued to FirstFire upon the cashless exercise of the FirstFire Warrant on March 12, 2026; (iii) the 15,000 Commitment Shares previously issued to FirstFire; (iv) shares issuable upon conversion of other outstanding convertible notes, including notes issued to CFI Capital, GS Capital Partners, and Quick Capital; (v) shares issuable upon conversion of the Series A, Series B, Series C, and Series D Preferred Stock; (vi) shares issuable upon exercise of the Representative Warrants; and (vii) shares held by our existing stockholders, including shares issued to our officers and directors, upon expiration of the applicable lock-up period. Additionally, up to 100,000 shares of our Common Stock may become eligible for sale pursuant to the Wolf Settlement Agreement dated April 27, 2026, including 45,000 shares currently held in book entry for Wolf’s benefit and up to 55,000 shares expected to be transferred to Wolf from Joseph T. Pitman, our former Chief Technology Officer and former Director, subject to negotiated leak-out limitations, under which Wolf’s daily sale limit is currently 25% of aggregate daily trading volume. These sales, or the possibility that these sales may occur, could have a material adverse effect on the market price of our Common Stock.

Of the remaining outstanding shares of Common Stock held by our existing shareholders after this offering, substantially all will be deemed restricted securities within the meaning of Rule 144 and may, subject to certain exceptions, be sold in the public market only if registered or if they qualify for an exemption from registration, including under Rule 144 under the Securities Act. Our executive officers, directors, and holders of 5% or more of our outstanding Common Stock (and all holders of securities exercisable for or convertible into shares of Common Stock) have agreed, subject to certain customary exceptions, not to sell or otherwise dispose of shares of our Common Stock for a period of six months following the closing of this offering, without the prior written consent of the Representative. The Representative, in its sole discretion and at any time without notice, may release all or any portion of the shares or securities subject to any such lock-up agreements. Upon expiration of the applicable lock-up period, a significant number of additional shares may become available for sale, which could adversely affect the market price of our Common Stock. See “Shares Eligible for Future Sale” and “Underwriting” for additional information.

Our stock price may be volatile and purchasers of our Common Stock could incur substantial losses.

The market price of our Common Stock may be highly volatile and may fluctuate or decline substantially as a result of a variety of factors, many of which are beyond our control, including:

The stock market in general has experienced significant price and volume fluctuations that have often been unrelated or disproportionate to operating performance of individual companies, particularly following a public offering of a company with a small public float. There is the potential for rapid and substantial price volatility of our Common Stock following this offering. These broad market factors may seriously harm the market price of our Common Stock, regardless of our actual or expected operating performance and financial condition or prospects, which may make it difficult for investors to assess the rapidly changing value of our Common Stock.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the market price for the shares and trading volume could decline.

The trading market for our Common Stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. If research analysts do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades our Common Stock or publishes inaccurate or unfavorable research about our business, the market price for our Common Stock would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for our Common Stock to decline.

Our principal shareholders will continue to have significant influence over corporate actions.

Our founders, executive officers, directors and director nominees, together with our Chief Engineer and our Chief Scientist (each a former director), in the aggregate, beneficially own 3,607,485 shares of Common Stock, equal to approximately 67.24% of shares outstanding as of October 16, 2026, based on 5,365,008 shares of Common Stock outstanding (post-split). Significant individual holdings include Paul S. Turin (Chief Engineer and former director), who beneficially owns 1,546,048 shares (28.82%), Gregory T. Delory (Chief Technology Officer and Director), who beneficially owns 1,104,556 shares (20.59%), and Edward Cabrera (Chief Executive Officer and Chairman), who beneficially owns 763,837 shares (14.24%). All share counts give effect to the 1-for-5 Reverse Stock Split and are stated on a post-split basis; ownership percentages are unaffected by the Reverse Stock Split. Upon the completion of this offering, these shareholders as a group will hold approximately 48.98% of shares outstanding (post-split), assuming no exercise by the underwriters of their over-allotment option and no exercise by the representative of the Representative Warrants. These shareholders currently have, and likely will continue to have, significant influence with respect to the election of our board of directors and approval or disapproval of all significant corporate actions. The concentrated voting power of these shareholders could have the effect of delaying or preventing an acquisition of the Company or another significant corporate transaction.

The Company’s founders, directors and executive officers currently own a majority of the Company and will continue to hold a significant percentage of our Common Stock following this offering

Additionally, the holdings of the Company’s directors and executive officers may increase in the future upon vesting or other maturation of exercise rights under any of the options or warrants they may hold or in the future be granted or if they otherwise acquire additional interest in the Company. The interests of such persons may differ from the interests of the Company’s other shareholders, including purchasers of securities in the offering. As a result, in addition to their board seats and offices, such persons will have significant influence over corporate actions requiring shareholder approval, , and may be able to determine their outcome, particularly if other shareholders do not vote or vote in different ways, including purchasers in the offering, may vote, including the following actions:

Such persons’ ownership may discourage a potential acquirer from making a tender offer or otherwise attempting to obtain control of the Company, which in turn could reduce the Company’s stock price or prevent the Company’s shareholders from realizing a premium over the Company’s stock price.

The Company has broad discretion in how the Company will use the net proceeds of this offering, and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds from this offering, including for any of the currently intended purposes described in the section entitled “Use of Proceeds.” Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management may not apply our cash from this offering in ways that ultimately increase the value of any investment in our securities or enhance stockholder value. The failure by our management to apply these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders. If we do not invest or apply our cash in ways that enhance stockholder value, we may fail to achieve expected financial results, which may result in a decline in the price of our shares of common stock and, therefore, may negatively impact our ability to raise capital, invest in or expand our business, acquire additional products or licenses, commercialize our product, or continue our operations.

Our potential future earnings and cash distributions to our stockholders may affect the market price of our securities.

Generally, the market price of our securities may be based, in part, on the market’s perception of our growth potential and our current and potential future cash distributions, whether from operations, sales, acquisitions or refinancings, and on the value of our businesses. For that reason, our securities may trade at prices that are higher or lower than our net asset value per share. Should we retain operating cash flow for investment purposes or working capital reserves instead of distributing the cash flows to our stockholders, the retained funds, while increasing the value of our underlying assets, may materially adversely affect the market price of our securities. Our failure to meet market expectations with respect to earnings and cash distributions and our failure to make such distributions, for any reason whatsoever, could materially adversely affect the market price of our securities.

Were our securities to be considered a penny stock, and therefore become subject to the penny stock rules, U.S. broker-dealers may be discouraged from effecting transactions in our securities.

Our securities may be subject to the penny stock rules under the Exchange Act. The SEC rules define a “penny stock,” as any equity security that has a market price of less than $5.00 per share or with an exercise price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, broker-dealers that derive more than 5% of their customer transaction revenues from transactions in penny stocks are required to deliver a standardized risk disclosure document that provides information about penny stocks, and the nature and level of risks in the penny stock market, to any non-institutional customer to whom the broker-dealer recommends a penny stock transaction. The broker-dealer must also provide the customer with the current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its salesperson and monthly account statements showing the market value of each penny stock held in the customer’s account. The bid and offer quotations and the broker-dealer and salesperson compensation information must be given to the customer orally or in writing before completing the transaction and must be given to the customer in writing before or with the customer’s confirmation. In addition, the penny stock rules require that before a transaction, the broker and/or dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. The transaction costs associated with penny stocks are high, reducing the number of broker-dealers who may be willing to engage in the trading of our securities. These additional penny stock disclosure requirements are burdensome and may reduce all the trading activity in the market for our securities. As long as our securities are subject to the penny stock rules, the holders of our securities may find it more difficult to sell their securities and cause a decline in the market value of our stock.

Our listing on Nasdaq Capital Market will subject us to more rigorous corporate governance and compliance requirements than those currently applicable to us as an OTC-quoted reporting company, and the associated costs and management burdens may adversely affect our business.

We are currently a reporting company subject to the informational and reporting requirements of the Exchange Act and our common stock is quoted on the OTCID marketplace. While we already comply with the SEC reporting requirements applicable to reporting companies generally, listing on the Nasdaq Capital Market will impose additional corporate governance obligations that do not currently apply to OTC-quoted companies. In particular, the Nasdaq corporate governance listing standards require, among other things, that a majority of our board of directors consist of independent directors, that we maintain an audit committee comprised of at least three independent directors satisfying the requirements of Rule 10A-3 under the Exchange Act, a compensation committee of independent directors, and a nominating and governance function. While we have taken initial steps to establish these committees in anticipation of our listing application, we cannot assure you that we will maintain compliance with all applicable Nasdaq governance requirements on an ongoing basis. Compliance with these requirements, together with the increased investor scrutiny and market expectations associated with exchange listing, will require additional legal, accounting, and investor relations resources, as well as payment of annual Nasdaq listing fees and potential increases in directors’ and officers’ liability insurance premiums. Our management will be required to devote substantial additional time to these expanded corporate governance and compliance obligations, which may divert attention and resources away from our core business operations and adversely affect our results of operations.

We are an “emerging growth company,” and the reduced reporting requirements applicable to emerging growth companies may make our Common Stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including exemption from compliance with the auditor attestation requirements of Section 404, reduced disclosure obligations regarding executive compensation and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of our initial public offering, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our Common Stock held by non-affiliates exceeds $700 million as of the end of our prior second fiscal quarter and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

In addition, under the JOBS Act, emerging growth companies may delay adopting new or revised accounting standards until such time as those standards apply to private companies. We may elect not to avail ourselves of this exemption from new or revised accounting standards and, therefore, may be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

We cannot predict if investors will find our Common Stock less attractive because we may rely on these exemptions. If some investors find our Common Stock less attractive as a result, there may be a less active trading market for our Common Stock and our share price may be more volatile.

Our Board will be authorized to issue and designate shares of our Preferred Stock in additional series without stockholder approval.

Our Articles of Incorporation, as amended, in conjunction with our Bylaws, authorize our Board, without the approval of our stockholders, to issue up to 20 million shares of our Preferred Stock, subject to limitations prescribed by applicable law, rules and regulations and the provisions of our Articles of Incorporation, as shares of Preferred Stock in one or more series, to establish from time to time the number of shares to be included in each such series and to fix the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations, or restrictions thereof. The powers, preferences and rights of these additional series of Preferred Stock may be senior to or on parity with our Common Stock, which may reduce its value.

Our management may use the proceeds of this offering in ways with which you may disagree or that may not be profitable.

Although we anticipate using the net proceeds from this offering as described under “Use of Proceeds,” we will have broad discretion as to the application of the net proceeds and could use them for purposes other than those contemplated by this offering. You may not agree with the manner in which our management chooses to allocate and use the net proceeds. Our management may use the proceeds for corporate purposes that may not increase our profitability or otherwise result in the creation of stockholder value. In addition, pending our use of the proceeds, we may invest the proceeds primarily in instruments that do not produce significant income or that may lose value.

We have never paid or declared any cash dividends on our Common Stock and we do not anticipate paying any cash dividends on our Common Stock in the foreseeable future.

We intend to retain all available funds and any future earnings to fund the development and expansion of our business. Any future determination to pay dividends will be at the discretion of our Board of Directors and will depend upon a number of factors, including our results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law, and other factors our Board of Directors deems relevant.

Risks Related to Legal Matters

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against companies following a decline in the market price of their securities. This risk is especially relevant for us because technology companies have experienced significant share price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

Our Amended and Restated Bylaws provide that the state courts of Florida or the federal district court for the Middle District of Florida will be the exclusive forum for certain litigation which may limit an investor’s or shareholder’s ability to obtain a favorable judicial forum for disputes with us.

Our Amended and Restated Bylaws (“Bylaws”) provide that unless the Company consents in writing to the selection of an alternative forum, the state courts of Florida (or if a state court within the state of Florida does not have jurisdiction the federal courts for the Middle District of Florida) will be the sole and exclusive forum for any and all legal proceedings concerning (a) any derivative action or proceeding brought on behalf of the Company; (b) any action asserting a claim of breach of a fiduciary duty owed by any current or former directors, officers or other employees of the Company to the Company or the Company’s shareholders; (c) any action arising pursuant to any provision of the Florida Business Corporation Act or our Articles of Incorporation or Bylaws (as either may be amended from time to time); or (d) any other action asserting a claim governed by the internal affairs doctrine.

This exclusive forum provision may limit an investor’s or shareholder’s ability to choose its preferred judicial forum for disputes with us or our directors, officers, employees or agents and limit a shareholder’s ability to bring a claim in a judicial forum it finds favorable, which may discourage the filing of lawsuits with respect to such claims. This exclusive forum provision may cause an investor or shareholder to incur additional costs for travel, attorney’s fees or other litigation cost, and the designated courts may reach different judgments or results than other courts.

The state forum provision may not apply to any causes of action arising under the Securities Act or the Exchange Act. There is uncertainty as to whether a court would enforce our exclusive forum provisions related to Securities Act claims. Investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

If a court were to find this exclusive forum provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in another jurisdiction, which could adversely affect our business and financial condition.

Our Amended and Restated Bylaws provide that U.S federal district courts shall be the exclusive forum for litigation against us or any director, officer or other employee or agent of ours arising under the Securities Act, which may limit an investor’s or shareholder’s ability to obtain a favorable judicial forum for disputes with us.

Article 8.2 of our Amended and Restated Bylaws provide that unless the Company consents in writing to the selection of an alternative forum, the U.S. federal district courts shall be the exclusive forum for the resolution of any complaint asserting a cause of action against the Company or any director, officer, other employee or agent of the Company arising under the Securities Act.

There is uncertainty as to whether a court would enforce our exclusive forum provisions related to Securities Act claims. Investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find this exclusive forum provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in another jurisdiction, which could adversely affect our business and financial condition.

Risks Relating to Technology and Intellectual Property

Our products and technologies are subject to U.S. export control laws and regulations, including the International Traffic in Arms Regulations (“ITAR”) and the Export Administration Regulations (“EAR”), and non-compliance could result in significant civil or criminal penalties, loss of export privileges, and reputational harm.

As an aerospace company that develops and delivers space-qualified hardware and systems for NASA and other government and commercial customers, many of our products and technologies are or may be subject to ITAR, administered by the U.S. Department of State, and/or EAR, administered by the U.S. Department of Commerce. We are required to register with the Directorate of Defense Trade Controls (“DDTC”), obtain required export licenses prior to any transfer of controlled technology to foreign persons or entities, and maintain ongoing compliance programs including employee training and cybersecurity measures to protect ITAR-controlled data. We are also required to evaluate each new contract involving activities or technology transfers in the space domain on an individual basis, as the applicable legal framework varies by customer, counterparty, and jurisdiction. The cost and complexity of compliance with these requirements is ongoing and can be significant. Although we believe we have been in compliance with applicable export control requirements, there can be no assurance that we will at all times be fully compliant or that our employees, contractors, or business partners will not inadvertently violate these requirements. Any failure to comply with ITAR or EAR could result in the suspension or revocation of our export privileges, significant fines and civil or criminal penalties, and reputational damage that could impair our ability to compete for government contracts, all of which could have a material adverse effect on our business, financial condition, and results of operations.

We have no registered patents, copyrights, or trademarks; our proprietary technologies are protected only by trade secrets and contractual arrangements that may not provide adequate protection; and U.S. government FAR data rights clauses may further limit our ability to commercialize technologies developed under government contracts.

The Company has no registered patents, copyrights, or trademarks. Our proprietary products and processes are maintained as trade secrets, protected through non-disclosure agreements, allocation of rights agreements, and employee proprietary information and inventions agreements. Trade secret protection is inherently limited because it depends on maintaining the secrecy of the underlying information. If our employees, contractors, or other parties breach their confidentiality obligations, or if our trade secrets are otherwise disclosed or independently discovered by competitors, our competitive position could be materially harmed.

Additionally, substantially all of our current revenue is derived from contracts with the U.S. government and prime contractors that flow down FAR data rights requirements. Under the applicable FAR “rights in data” clauses, we claim only limited rights to key technologies on a case-by-case basis. As a result, the U.S. government may have the right to use, reproduce, release, perform, display, or disclose technical data and computer software developed under our contracts, and may authorize others to do so, including our competitors, without compensation to us. This exposure is particularly significant for technologies developed under our SBIR awards and other NASA-funded programs. While we seek to negotiate appropriate data rights protections on a contract-by-contract basis, we may not always be successful in doing so. To the extent our commercially valuable innovations are developed wholly or in part under government funding, our ability to protect and commercialize those technologies for non-government applications (including our Space Based Solar Power initiative) may be limited.

Our inability to adequately protect our proprietary technology - whether through the inherent limitations of trade secret protection or the government’s rights under FAR data rights clauses - could allow competitors to replicate our innovations, erode our competitive advantages, impair our competitive position, reduce the value of our technology assets, and have a material adverse effect on our business, financial condition, and results of operations.

Cybersecurity threats, including ransomware attacks, data breaches, and intrusions by nation-state actors, pose a material risk to our operations, and any significant cybersecurity incident could disrupt our business, compromise our proprietary technology and sensitive government-related data, and result in significant liability and reputational harm.

As an aerospace company that develops and delivers space-qualified hardware and systems for NASA and other government customers, we maintain sensitive technical data, proprietary engineering information, and in some cases data subject to ITAR or classified handling requirements. We rely on information technology systems to process, transmit, store, and protect this information, and we depend on a third-party vendor to assist with network security monitoring and cybersecurity risk management. Despite these measures, our security controls may not prevent all disruptions, unauthorized access attempts, malware or ransomware incidents, data breaches, or other cyber-attacks. Because of the frequently changing nature of attack techniques, including attacks designed to remain dormant until triggered, we may be unable to anticipate or defend against sophisticated threats in a timely manner. A successful cyber-attack that compromises our proprietary technical data or engineering processes could allow competitors to replicate our innovations, degrade our competitive position, expose us to legal liability, and damage customer and government relationships. The costs of responding to any such incident, implementing remediation measures, and managing any resulting legal proceedings may not be fully covered by insurance and could have a material adverse effect on our business, financial condition, and results of operations. To date, the Company has not experienced any material cybersecurity incident; however, there can be no assurance that we will not be adversely impacted in the future.

Our Space Based Solar Power initiative is at an early stage of development, involves significant technological and commercial uncertainty, and may never be successfully commercialized.

A core element of our growth strategy is the development of Space Based Solar Power (“SBSP”), which involves deploying solar collection systems in orbit and transmitting energy wirelessly to Earth. We are currently in the early stages of developing the enabling technologies, including our HelioSat advanced deployable system, and we intend to demonstrate an initial in-space SBSP system by 2030. SBSP technology has not yet been demonstrated at commercial scale anywhere in the world, and the path to commercialization involves substantial engineering challenges, regulatory requirements, and capital investment that may not be achievable on the timelines we anticipate or at all. Our ability to develop SBSP technology will depend on, among other things: our ability to secure additional financing; the continued availability of government SBIR funding and support; successful development of advanced deployable structures, wireless power transmission systems, and related technologies; resolution of applicable space law, spectrum allocation, and regulatory issues; and achievement of a commercially viable levelized cost of energy. Many of these factors are outside our control. In addition, larger and better-capitalized competitors, including established aerospace and energy companies, may develop competing SBSP solutions that are more technologically advanced or less costly than ours. If we are unable to successfully develop and commercialize SBSP technology, a significant portion of our anticipated long-term growth potential would be unrealized, which could have a material adverse effect on our business, financial condition, and results of operations.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

We make forward-looking statements under the “Summary,” “Risk Factors,” “Business,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and in other sections of this prospectus. In some cases, you can identify these statements by forward-looking words such as “may,” “might,” “aim,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “will” or “continue,” and the negative of these terms and other comparable terminology. These forward-looking statements, which are subject to known and unknown risks, uncertainties, and assumptions about us, may include projections of our future financial performance based on our growth strategies and anticipated trends in our business. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance, or achievements to differ materially from the results, level of activity, performance, or achievements expressed or implied by the forward-looking statements, including, but not limited to:

While we believe we have identified material risks, these risks and uncertainties are not exhaustive. Other sections of this prospectus describe additional factors that could adversely impact our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not possible to predict all risks and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance, or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy or completeness of any of these forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. We are under no duty to update any of these forward-looking statements after the date of this prospectus to conform our prior statements to actual results or revised expectations and we do not intend to do so.

You should read this prospectus and the documents that we reference in this prospectus and have filed with the SEC as exhibits to the registration statement of which this prospectus is a part with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect.

We caution you not to place undue reliance on the forward-looking statements, which speak only as of the date of this prospectus.

USE OF PROCEEDS

Primary Offering Proceeds

We estimate that the net proceeds from the primary offering will be approximately $7.993 million, after deducting underwriting discounts of 7% of gross proceeds, a non-accountable expense allowance of 1% of gross proceeds, and estimated offering expenses of approximately $286,202, and assuming no exercise of the over-allotment option. We do not currently know the final number of shares to be sold or the public offering price per share, both of which will be determined upon Nasdaq listing and by agreement with the Representative. Less than five percent of the net offering proceeds, excluding underwriting compensation, will be used to repay loans or credit facilities extended by, or otherwise directed to, Edward Cabrera, any participating FINRA member, its affiliates and associated persons, in the aggregate.

We currently expect to use the net proceeds from the primary offering for the following purposes:

Amounts and timing of our actual expenditures will depend upon a number of factors, including demand for our products, operating costs, debt repayment obligations, and other factors described under “Risk Factors.” Accordingly, our management will have flexibility in applying the net proceeds from this primary offering. An investor will not have the opportunity to evaluate the economic, financial, or other information on which we base our decisions on how to use the proceeds.

Pending our application of the net proceeds, we plan to invest such proceeds in short-term, investment-grade, interest-bearing securities and depository institutions.

DIVIDEND POLICY

We have never paid or declared any cash dividends on our Common Stock and we do not anticipate paying any cash dividends on our Common Stock in the foreseeable future. We intend to retain all available funds and any future earnings to fund the development and expansion of our business. Any future determination to pay dividends will be at the discretion of our Board of Directors and will depend upon a number of factors, including our results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law, and other factors our Board of Directors deems relevant.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization as of July 31, 2026:

The as adjusted information below is illustrative only, and our capitalization following the completion of this offering will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing.

You should read this table in conjunction with the information contained in “Use of Proceeds,” “Description of Securities” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as our financial statements and related notes thereto included elsewhere in this prospectus.

The above table excludes shares issuable under outstanding options, other convertible notes, the Representative Warrants, and the Series D Preferred Stock conversion shares. The actual column is presented as of July 31, 2026 and does not give effect to transactions occurring after July 31, 2026. The pro forma as-adjusted column additionally gives effect to the primary offering at an assumed offering price of $4.50 per share, after deducting underwriting discounts and commissions and estimated offering expenses. Notes payable - Other includes notes payable of $750,500 (current $680,500 and non-current $70,000) and convertible notes payable, net of unamortized debt discount, of $202,930. The common stock actual column amount of $9,078,778 represents the combined total of common stock ($8,978,803) and additional paid-in capital ($99,975) as presented in the July 31, 2026 balance sheet.

DILUTION

If you invest in our Common Stock in this offering, your interest will be immediately diluted to the extent of the difference between the initial public offering price per share of Common Stock in this offering and the pro forma as adjusted net tangible book value per share of Common Stock after this offering. Dilution results from the fact that the initial public offering price per share is substantially in excess of the net tangible book value per share of Common Stock. As of July 31, 2026, we had a historical net tangible book value (deficit) of $(3,141,834), or approximately $(0.59) per common share (post-split), based on 5,190,024 shares of Common Stock outstanding. Our net tangible book value (deficit) per share represents total tangible assets less total liabilities, divided by the number of shares of Common Stock outstanding on July 31, 2026. All share counts and per-share figures in this section give effect to the 1-for-5 Reverse Stock Split and are presented on a post-split basis.

Our pro forma net tangible book value as of July 31, 2026, and giving effect to the offering of 2,000,000 shares of our Common Stock (post-split) and the application of proceeds therefrom and giving effect to estimated underwriting discounts and expenses payable by us in this offering, would have been $4,851,530, or $0.65 per share of Common Stock (post-split), based on an assumed public offering price of $4.50 per share (post-split), which is the midpoint of the estimated price range per share set forth on the cover page of this prospectus. Pro forma net tangible book value per share represents total tangible assets less total liabilities, divided by the number of shares to be issued and outstanding immediately after this offering as shown above, assumes that all shares offered hereby are sold and no exercise by the underwriters of their over-allotment option to purchase additional shares.

Assuming the number of shares of Common Stock offered by us, as set forth on the cover page of this prospectus, remains the same, after deducting the underwriting discount and estimated offering expenses payable by us, a $1.00 increase in the assumed initial public offering price of $4.50 per share, which is the midpoint of the estimated price range per share set forth on the cover page of this prospectus, would increase the pro forma tangible book value attributable to new investors purchasing shares in this offering by $3.93 per share and increase the dilution to new investors by $2.15 per share.

Assuming the number of shares of Common Stock offered by us, as set forth on the cover page of this prospectus, remains the same, after deducting the underwriting discount and estimated offering expenses payable by us, a $1.00 decrease in the assumed initial public offering price of $4.50 per share, which is the midpoint of the estimated price range per share set forth on the cover page of this prospectus, would decrease the pro forma tangible book value attributable to new investors purchasing shares in this offering by $0.99 per share and decrease the dilution to new investors by $3.09 per share.

The following table summarizes, on the pro forma as adjusted basis described above, the differences between the number of shares of Common Stock purchased from us, the total consideration paid to us, and the average price per share paid by existing stockholders and by new investors. As the table shows, new investors purchasing shares of our Common Stock in this offering will pay an average price per share substantially higher than our existing stockholders paid. The table below assumes an initial public offering price of $4.50 per share (post-split), which is the midpoint of the estimated price range per share set forth on the cover page of this prospectus, for shares purchased in this offering and excludes underwriting discount and estimated offering expenses payable by us:

If the underwriters were to exercise their over-allotment option to purchase additional shares of our Common Stock from us in full, the percentage of shares of our Common Stock held by existing stockholders who are directors, officers, or affiliated persons as of October 16, 2026 would be approximately 47% and the percentage of shares of our Common Stock held by new investors would be approximately 30%.

Assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, a $1.00 increase (decrease) in the assumed initial public offering price of $4.50 per share, which is the midpoint of the estimated price range set forth on the cover page of this prospectus, would increase (decrease) total consideration paid by new investors and total consideration paid by all stockholders by approximately $2,000,000.

To the extent that we grant options to our employees in the future and those options are exercised or other issuances of Common Stock are made, there will be further dilution to new investors. In addition, the above discussion and tables do not account for additional potential dilution from: (i) the conversion of the Series A, Series B, Series C, or Series D Preferred Stock; (ii) the conversion of other outstanding convertible notes issued to CFI Capital, GS Capital Partners, and Quick Capital; (iii) the exercise of outstanding employee stock options (89,168 options, post-split); and (iv) the Representative Warrants issued to the underwriter. Each of these instruments could result in significant further dilution to new investors. Except as otherwise indicated, the above discussion and tables are based on 7,365,008 shares of our Common Stock outstanding (post-split), reflecting 5,365,008 shares outstanding as of October 16, 2026 (as adjusted to give effect to the 1-for-5 Reverse Stock Split), and the 2,000,000 shares offered hereby, and assumes that all shares offered hereby are sold and no exercise by the underwriters of their over-allotment option to purchase additional shares.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes thereto included elsewhere in this prospectus. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the section entitled “Risk Factors.” The following discussion covers the fiscal year ended October 31, 2025 compared to the fiscal year ended October 31, 2024, as well as the three and nine months ended July 31, 2026 compared to the three and nine months ended July 31, 2025.

Overview of Operations

Heliospace, our wholly owned subsidiary, is an aerospace company specializing in the design, engineering, assembly and test of space flight qualified hardware, providing systems engineering, modeling, analysis, integration and test services to customers in government, commercial, private and non-profit markets. Heliospace designs, fabricates, assembles and tests space qualified hardware, including radar antennas for the NASA Europa Clipper mission, the antennas for the SunRISE CubeSat constellation, and deployable systems and sensors for numerous lunar landers and the Mars Sample Return program. Heliospace also provides systems engineering, integration and test, and mission formulation services, including support for the design, testing, and launch of the James Webb Space Telescope, formulation and design of the Roman Space Telescope, Habworlds Observatory, Mars Sample Return, and the Atmospheric Observing System.

In January 2024, via a share exchange accounted for as a reverse acquisition, Web3 Corporation, a Florida corporation that was originally incorporated under the name Stirling Bridge Group, Inc. and was a specialized small business venture lender, acquired 100% of the stock of Heliospace, and changed its name from Web3 Corporation to Helio Corporation (the “Business Combination”). Heliospace was the accounting acquirer in the Business Combination and was determined to be the sole predecessor of Helio Corporation. Accordingly, this discussion and analysis, and the condensed consolidated financial statements included elsewhere in this Quarterly Report, reflect the financial condition and results of operations of Helio Corporation and its sole consolidated subsidiary, Heliospace, after the Business Combination and of Heliospace prior to the Business Combination.

Trends, Events, and Uncertainties

Government Budget Uncertainty and Proposed NASA Cuts

A significant portion of our revenue is derived from contracts with the U.S. federal government, including through NASA, where our subsidiary, Heliospace, provides mission-critical components and engineering services for science and exploration missions. Accordingly, our financial condition and results of operations are influenced by trends in federal discretionary spending, particularly in space science and technology programs.

One key emerging trend is the proposed shift in federal budget priorities under the Trump administration. In April 2025, the administration released its draft budget proposal for fiscal year 2026, which recommends a significant reduction in overall discretionary spending, including an approximately 50% cut to NASA’s Science Mission Directorate. If enacted, this proposal would reduce funding for core science programs such as astrophysics, heliophysics, Earth science, and planetary science—areas directly aligned with Heliospace’s technical capabilities and historical contract activity.

Although this proposal remains subject to Congressional negotiation and approval, the magnitude of the proposed cuts and the administration’s stated intent to reprioritize government resources away from space science programs present a material uncertainty for our future growth. Any resulting reduction, delay, or cancellation of NASA programs could reduce the number of available contracts, increase competition for limited awards, and adversely impact our future revenue and profitability.

In addition, broader fiscal challenges at the federal level—such as the rising national debt, persistent budget deficits, and the risk of government shutdowns or extended continuing resolutions—could result in delays to contract funding or payments, reduced availability of new program opportunities, and increased uncertainty in long-term planning. These macroeconomic pressures may also negatively affect private sector customers that rely on or benefit from government-funded space and research initiatives.

As we execute our expansion plans, we have continued to pursue and acquire additional revenue from private, commercial, and defense department sources., However, these plans are subject to risks and uncertainties, and there can be no assurance that they will succeed or fully offset the effects of any reduction in government spending.

Note Defaults

As of July 31, 2026, the Company was not in default under any of its outstanding promissory notes.

During fiscal year 2026 and subsequent to July 31, 2026, the Company completed multiple financing transactions to support its liquidity needs (see Notes 6, 13, and 14).

These notes bear interest at rates generally ranging from approximately 6% to 12% per annum (subject to higher default rates) and have maturities ranging from October 2026 through July 2027. The proceeds from these financings were used for working capital and general corporate purposes.

Debt Obligations and Contractual Commitments

As of July 31, 2026, the Company had outstanding debt from unrelated parties under notes payable with an aggregate principal balance of $750,500. These notes bear interest at rates of 6.00% and 12.00% per annum and mature within the next two fiscal years. Certain of these notes are secured by the Company’s accounts receivable and by shares of common stock pledged by a shareholder, and certain notes permit acceleration upon the occurrence of specified events.

The Company’s ability to service its debt obligations will depend on its future operating performance and its ability to obtain additional financing.

Revenue Decline

Revenue has declined over the past several fiscal periods. Revenue for the fiscal year ended October 31, 2025 decreased by 44% to $3,875,793 from $6,891,223 for the fiscal year ended October 31, 2024, which itself reflected a decline of approximately 25% from $9,209,329 in fiscal year 2023. Contributing factors to the FY2025 decline include continuing budget cuts to NASA programs enacted by the current administration, combined with the extended government shutdown, which reduced the overall volume of work available to us. During the fiscal year ended October 31, 2025, we serviced eleven customers-two direct government customers, four private or commercial customers, three nonprofit customers for whom we manufactured products as a subcontractor for their government customer, and two commercial customers whose source of funds was private investment-compared to thirteen customers during fiscal year 2024. For the nine months ended July 31, 2026, revenue declined 54% to $1,543,492 from $3,384,423 for the nine months ended July 31, 2025, and for the three months ended July 31, 2026, revenue declined 25% to $590,626 from $784,587 for the three months ended July 31, 2025. During the nine months ended July 31, 2026, we serviced six customers—one government customer, one public company, three nonprofit or not-for-profit customers under government contracts, and one private customer—compared to eleven customers for the nine months ended July 31, 2025. This continued and accelerating contraction in our customer base, combined with our dependence on government-funded programs, increases our vulnerability to further budget-driven disruptions.

Cybersecurity Risk and Ongoing Threat Landscape

As a government contractor and developer of advanced aerospace technology, we operate in a highly sensitive and data-driven environment. Cybersecurity risks—including ransomware attacks, data breaches, intellectual property theft, and attempted intrusions by nation-state actors—continue to increase in frequency and sophistication across our industry. Like many companies operating in the defense and aerospace sectors, we remain a potential target for both criminal and geopolitical cyber threats.

We have implemented security protocols, systems monitoring, and access controls to protect our infrastructure and proprietary information, including information related to our work with NASA and other government agencies. However, cybersecurity is an evolving threat landscape, and there can be no assurance that our efforts will prevent all attacks or unauthorized access. A successful breach could disrupt our operations, compromise confidential data, harm our reputation, result in regulatory investigations, or expose us to legal claims and financial losses.

We will continue to invest in cybersecurity tools, training, and third-party audits to strengthen our defenses, and we are evaluating compliance with emerging federal cybersecurity requirements. Nonetheless, future cybersecurity incidents could materially affect our business, financial condition, or results of operations.

Results of Operations

Fiscal Year Ended October 31, 2025 Compared to Fiscal Year Ended October 31, 2024

Revenue. Revenue decreased by $3,015,430, or 44%, to $3,875,793 for the fiscal year ended October 31, 2025, from $6,891,223 for the fiscal year ended October 31, 2024. The decrease reflected a lower overall volume of work, driven primarily by continuing budget cuts to NASA programs and the extended government shutdown, resulting in a reduction in both the number of active contracts and the size of work awarded. We serviced eleven customers in fiscal year 2025 compared to thirteen in fiscal year 2024.

Cost of Revenue. Cost of revenue decreased by $1,200,571, or 29%, to $2,952,619 for the fiscal year ended October 31, 2025, from $4,153,190 for the fiscal year ended October 31, 2024. As a percentage of revenue, cost of revenue increased to approximately 75% in fiscal year 2025 from approximately 60% in fiscal year 2024. The increase in cost of revenue as a percentage of revenue was driven by a lower overall revenue base against certain fixed costs, a loss on one fixed-price contract, and charges to one services contract beyond the hours originally allocated.

Gross Profit. Gross profit decreased by $1,814,859 to $923,174 for the fiscal year ended October 31, 2025, from $2,738,033 for the fiscal year ended October 31, 2024. Gross margin declined to approximately 23.8% in fiscal year 2025 from approximately 39.7% in fiscal year 2024, reflecting the impact of lower revenue on fixed and semi-fixed cost of revenue components.

Operating Expenses. Total operating expenses increased by $138,740, or 3%, to $4,621,928 for the fiscal year ended October 31, 2025, from $4,483,188 for the fiscal year ended October 31, 2024. General and administrative expenses increased to $2,933,534 from $2,799,805, an increase of $133,729. Personnel expenses decreased to $436,947 from $473,527. Professional fees increased to $462,592 from $359,077, reflecting higher legal and accounting costs. Research and development costs included within general and administrative expenses were $215,088 for fiscal year 2025, compared to $325,381 for fiscal year 2024.

Other Expense. Total other expense, net increased to $(331,717) for the fiscal year ended October 31, 2025 from $(117,528) for the fiscal year ended October 31, 2024. Interest expense, net increased to $327,873 from $89,178, reflecting the higher outstanding debt balance during fiscal year 2025 compared to the prior year. Amortization of debt discount was $8,188 in fiscal year 2025, compared to nil in fiscal year 2024.

Net Loss. Net loss increased by $2,167,788 to $(4,030,471) for the fiscal year ended October 31, 2025, from $(1,862,683) for the fiscal year ended October 31, 2024. The increase in net loss reflects the significant revenue decline combined with a substantially fixed operating expense base and increased interest expense.

Nine months Ended July 31, 2026 to the Nine months Ended July 31, 2025

The following table provides certain selected financial information of Helio Corporation for the periods presented:

Revenue. Revenue for the nine months ended July 31, 2026 decreased by 54% to $1,543,492 from $3,384,423 for the nine months ended July 31, 2025, reflecting a lower overall volume of work compared to the prior nine months. Contributing factors include continuing budget cuts to NASA programs enacted by the current administration, combined with the extended government shutdown. During the nine months ended July 31, 2026, we serviced six customers, one of which was a government customer, one public company and three non/not-for-profit customers who were under government contracts, and one private customer. For the nine months ended July 31, 2025, we serviced eleven customers, of which two were direct government customers, one was a commercial customer with private funding, five were commercial customers and three were non/not-for-profit customers for whom we manufactured products as a subcontractor for their government customer 

Cost of Revenue. The 66% decrease in cost of revenue for the nine months ended July 31, 2026 to $905,106 from $2,680,940 for the nine months ended July 31, 2025 mainly reflected the decreased business volume described above. As a percentage of revenue, cost of revenue amounted to 59% and 79% in the nine months ended July 31, 2026 and 2025, respectively. Cost of revenue as a percentage of revenue decreased by approximately 20% due to increased operational efficiency on several new contracts that commenced in Q3 2026.

Operating Expenses.

Overall operating expenses increased by $1,324,555, or 39%, to $4,715,947 for the nine months ended July 31, 2026, as compared to $3,391,392 for the nine months ended July 31, 2025, driven by professional fees and higher G&A expenses and R&D activities.  Additionally, the Company issued stock for services to the CEO, CFO and consultants for an aggregate value of $2,481,918.

Other Expense. Our other expenses are comprised of interest expense, amortization of debt discount, change in fair value of derivative liabilities, gain on extinguishment of derivative liabilities, loss on issuance of derivative, loss on modification of debt and loss on debt extinguishment. Overall other expenses increased by $2,576,594, or 1308%, to $2,773,614 for the nine months ended July 31, 2026, as compared to $197,020 for the nine months ended July 31, 2025. We recorded $293,123 in interest expense in the nine months ended July 31, 2026 compared to $197,020 in the nine months ended July 31, 2025, reflecting our increased amount of average outstanding debt and increased rates of interest thereunder. In the nine months ended July 31, 2026 we recorded amortization of debt discount of $864,738, the change in fair value of derivative liabilities of $731,919, which was due to the issuance of convertible debt and preferred stock, loss on issuance of derivative in the amount of $105,527, a gain on extinguishment of derivative liabilities in the amount of $509,476, a loss on modification of debt in the amount of $51,480 and a loss on debt extinguishment in the amount of $1,236,303.

We have not recorded income tax expense or benefit in the nine months ended July 31, 2026 and 2025 (because of our tax loss carryforwards). We had approximately $11,836,000 of net operating loss carry forwards to offset future federal taxable income as of July 31, 2026.

The net operating loss (“NOL”)  carry forward is subject to review and possible adjustment by the Internal Revenue Service and state tax authorities. Under the Internal Revenue Code (“IRC”) Sections 382 and 383, annual use of the Company’s net operating loss carryforwards and research credit carryforwards to offset taxable income and tax, respectively, may be limited based on cumulative changes in ownership. The Company has not completed an analysis to determine whether any such limitations have been triggered as of July 31, 2026. The annual limitation, if any, will be determined based on the value of the Company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future nine months.

Net Loss. Our net loss for the nine months ended July 31, 2026 was $6,851,175, compared to a net loss of $2,884,929 for the nine months ended July 31, 2025. The change was due to the reasons discussed above.

Because of historical and expected operating losses and net operating cash flow deficits, there is substantial doubt about the Company’s ability to continue as a going concern for twelve months from the issuance of the condensed consolidated financial statements, which is not alleviated by management’s plans. The condensed consolidated financial statements have been prepared under the going concern basis of accounting. These condensed consolidated financial statements do not include any adjustments that might be necessary from the outcome of this uncertainty.

Three Months Ended July 31, 2026 to the Three Months Ended July 31, 2025

The following table provides certain selected financial information of Helio Corporation for the periods presented:

Revenue. Revenue for the three months ended July 31, 2026 decreased by 25% to $590,626 from $784,587 for the three months ended July 31, 2025, reflecting a lower overall volume of work compared to the prior three months. Contributing factors include continuing budget cuts to NASA programs enacted by the current administration. During the three months ended July 31, 2026 we serviced six customers, of which one was a direct government customer, one was a public company, three were non/not-for-profit customers for whom we manufactured products as a subcontractor for their government customer, and one private customer. For the three months ended July 31, 2025, we serviced nine customers, two of which were direct government customers, four were commercial customers and two were non/not-for-profit customers for whom we manufactured products as a subcontractor for their government customer, and one private customer.

Cost of Revenue. The 53% decrease in cost of revenue for the three months ended July 31, 2026 to $325,534 from $686,197 for the three months ended July 31, 2025 mainly reflected the decreased business volume described above. As a percentage of revenue, cost of revenue amounted to 55% and 87% in the three months ended July 31, 2026 and 2025, respectively. Cost of revenue as a percentage of revenue decreased by approximately 32% due to increased operational efficiency on several new contracts that commenced in Q3 2026.

Operating Expenses.

Overall operating expenses decreased by $188,960, or 19%, to $811,324 for the three months ended July 31, 2026, as compared to $1,000,284 for the three months ended July 31, 2025, in both cases driven by lower personnel expenses and G&A expenses.

Other Expense. Our other expenses are comprised of interest expense, amortization of debt discount, change in fair value of derivative liability, gain on extinguishment of derivative liabilities, loss on issuance of derivative, loss on modification of debt and loss on debt extinguishment. Overall other expenses increased by $876,398, or 1794%, to $925,258 for the three months ended July 31, 2026, as compared to $48,860 for the three months ended July 31, 2025. We recorded $54,070 in interest expense in the three months ended July 31, 2026 compared to $48,860 in the three months ended July 31, 2025, reflecting our increased amount of average outstanding debt and increased rates of interest thereunder. In the three months ended July 31, 2026 we recorded amortization of debt discount of $420,163, the change in fair value of derivative liabilities of $412,977, which was due to the issuance of convertible debt and preferred stock, loss on issuance of derivative in the amount of $105,527, a gain on extinguishment of derivative liabilities in the amount of $420,239, a loss on debt extinguishment in the amount of $352,760.

Net Loss. Our net loss for the three months ended July 31, 2026 was $1,471,490, compared to a net loss of $950,754 for the three months ended July 31, 2025. The change was due to the reasons discussed above.

Because of historical and expected operating losses and net operating cash flow deficits, there is substantial doubt about the Company’s ability to continue as a going concern for twelve months from the issuance of the condensed consolidated financial statements, which is not alleviated by management’s plans. The condensed consolidated financial statements have been prepared under the going concern basis of accounting. These condensed consolidated financial statements do not include any adjustments that might be necessary from the outcome of this uncertainty.

Liquidity and Capital Resources

Fiscal Year Ended October 31, 2025. As of October 31, 2025, we had cash and cash equivalents of $7,305. We have historically funded our operations through a combination of operating cash flows, debt financing, and equity issuances. Net cash used in operating activities was $(2,065,017) for the fiscal year ended October 31, 2025, compared to $(1,560,375) for the fiscal year ended October 31, 2024, reflecting increased net losses partially offset by working capital changes, including a decrease in accounts receivable of $900,776. Net cash provided by financing activities was $1,520,770 for the fiscal year ended October 31, 2025, compared to $1,607,592 for the fiscal year ended October 31, 2024, reflecting proceeds from new debt issuances partially offset by repayments.

Nine Months Ended July 31, 2026. As of July 31, 2026, the Company had cash and cash equivalents of $520,504 and has historically incurred operating losses and negative cash flows from operations. The Company has funded its working capital, research and development activities, capital expenditures, and other commitments primarily through loans from the Company’s executive officers and directors and other debt financings. The Company has also issued equity securities in non-cash transactions, including in connection with services rendered and debt-related arrangements. The Company expects to continue to incur operating losses and negative operating cash flows as it advances its business and executes its strategic initiatives.

The Company’s primary liquidity requirements include funding operating expenses, research and development activities, engineering and technical personnel costs, general and administrative expenses, professional fees, and costs associated with maintaining its public company reporting obligations. As of July 31, 2026, the Company’s ability to meet its obligations as they become due depend, and is expected to continue to depend, on its ability to obtain additional financing through debt or equity issuances, strategic transactions, or other capital-raising activities.

Subsequent Financing Activities. Subsequent to July 31, 2026, the Company executed a note payable agreement for $165,000 from which $38,050  in fees were deducted for net proceeds of $126,950.

Going Concern. The audit reports on our financial statements for the fiscal years ended October 31, 2025 and October 31, 2024 each included explanatory paragraphs expressing substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern is dependent upon our ability to raise additional capital through this offering and other financing activities and to achieve profitability. Management’s plans include pursuing additional debt and equity financings, strategic partnerships, and other capital-raising initiatives, including the proceeds of this offering. However, there can be no assurance that such financing will be available on acceptable terms, or at all. If we are unable to raise sufficient capital or achieve profitability, we may be forced to curtail our operations, liquidate our assets, or cease operations entirely.

Capital Requirements. We do not believe that our current cash resources are sufficient to fund our operations beyond the near term without the proceeds from this offering or other financings. We estimate that the net proceeds from this offering, if completed, would be approximately $7.993 million, after deducting underwriting discounts and commissions and estimated offering expenses. We intend to use such proceeds primarily for: (i) repayment of outstanding promissory notes; (ii) research and development; (iii) sales, marketing, and business development; (iv) upgraded facilities and infrastructure; (v) manufacturing improvements; and (vi) general and administrative and working capital purposes. See “Use of Proceeds.”

Cash Flows

Cash Flows Used in Operating Activities

Our operating cash flow results were affected by the aging and timing of certain working capital items. During the nine months ended July 31, 2026 and 2025, our negative operating cash flow was attributed mainly to our net loss, as described above.

During the nine months ended July 31, 2026, the Company reported $1,937,196 of cash used in operating activities. The Company’s negative operating cash flow was attributed mainly to a net loss of $6,851,175, decrease in lease obligations of $314,060, a decrease in accrued compensation in the amount of $229,575 and a gain on extinguishment of derivative liability in the amount of $509,476. This was offset by a loss on debt extinguishment in the amount of $1,236,303, amortization of debt discount in the amount of $864,738, common stock issued for services in the amount of $2,481,918, and change in fair value of derivative liabilities in the amount of $731,919.

During the nine months ended July 31, 2025, the Company reported $(1,549,753) of cash used in operating activities. The Company’s negative operating cash flow was attributed mainly to a net loss of $(2,884,929) and is partially offset by a decrease in accounts receivable of $788,869, and a decrease in work in process of $174,537.

Recent Moon Mission

Our delivered space qualified hardware continues to perform on space recent flight missions. On March 17, 2025, the Company announced the successful deployment of its hardware on Firefly Aerospace’s Blue Ghost Mission 1 (BGM1) lander. Heliospace provided deployable mechanisms and sensors as part of the Lunar Magnetotelluric Sounder (LMS) experiment. Led by Southwest Research Institute, LMS is designed to study the interior of the Moon by measuring low frequency electromagnetic fields. Heliospace designed and built unique remote electrodes that deploy in four directions up to 60 feet away from the lander, forming a large low frequency antenna on the lunar surface. Heliospace also provided a separate compact boom which deploys a magnetometer sensor upwards from the lander deck to make accurate measurements of magnetic fields. These systems work together to enable the LMS experiment to achieve key scientific objectives in resolving the internal structure of Moon’s mantle.

Market Overview

The global space marketplace is projected to grow from over $600 billion today to over $1.8 trillion by 2035 (World Economic Forum & McKinsey & Company 2024). We believe the growing recognition of the commercial potential of in-space activities, sustained science and technology efforts by both government and private entities, combined with increasing geopolitical concerns will continue to accelerate this trend. Our target markets include hardware, payloads and infrastructure for Earth orbiting and lunar applications for government, commercial, and private customers with a projected market size of $11-12 billion by 2030, according to the McKinsey & Company report 2024. As humanity continues to expand its capabilities in space, additional opportunities exist in space infrastructure for a variety of purposes. Of these, space-based energy production is beginning to see substantial traction. Space-Based Solar Power (SBSP) is one such long-standing goal that has seen a resurgence due to falling launch costs combined with new technologies, with a conservative market size of $0.7-0.8 billion today and expanding to $3-4.5 billion by 2030, and scaling into the hundreds of billions by 2040, according to McKinsey & Company report 2024.

We intend to continue expansion into the development of space qualified hardware and payloads, for which we believe we have a significant foothold with our existing products and services, and bring to market a range of aerospace products currently in development under multiple SBIR Phase II programs. Building upon this foundation of general aerospace capability, Heliospace has embarked on the development of space-based energy infrastructure, in a vertically-integrated plan to bring reliable clean energy to Earth via SBSP.

The market for space hardware, systems and services has historically been highly fragmented, with few scaled, capable competitors. The capabilities of the legacy providers have been shaped by longstanding government procurements as well as the established communications and navigation equipment markets. There has been significant consolidation over the past few decades, resulting in fewer and less agile or innovative organizations. Cost control, performance and quality remain a challenge for some established incumbents. This landscape has opened the door to new entrants into the marketplace, with several recent space company IPOs over the past year. These and other new providers are poised to serve the rapidly growing space economy with new applications and revenue opportunities that many current hardware and services providers are ill equipped to address. To succeed in this evolving market, aerospace companies in particular must be both innovative and agile to answer the needs of emerging new applications and customers. Heliospace aims to expand into these growing market segments by offering responsive, tailored solutions to both established and new customers providing innovative, cost-effective space systems and products while pioneering space-based energy as a service.

Customer Concentration

Our customers are concentrated in the space industry. While we have a strategy to diversify our sources of revenue (See “Company Growth Strategy” for a description of our strategy), approximately 70% and 75% of our revenue for the fiscal year ended October 31, 2025 and the fiscal year ended October 31, 2024, respectively, was derived, directly or indirectly, from U.S. government sources, either as a prime contractor or as a subcontractor. In each of these periods, more than 67% of our revenue was attributable to three customers. One of these customers, a prime contractor under an indefinite delivery/indefinite quantity (“IDIQ”) contract with NASA, accounted for approximately 31% of our revenue in the fiscal year ended October 31, 2025, and 27% of our revenue in the fiscal year ended October 31, 2024.

Current Hardware and Services Capabilities

We have successfully scaled as a space hardware and services company providing solutions to government, commercial, and non-profit customers. This includes hardware and services for over five space missions and hardware deliveries for over four additional missions launching in the near term. We leverage decades of management experience developing hardware capabilities that were successfully used in space for NASA and other space agencies and organizations. Our current commercial-stage hardware includes deployable mechanisms, antennas, booms, structures, and sensors. Our hardware is generally custom designed to customer specifications, assembled, tested and delivered fully qualified and ready for flight as a complete end-to-end solution. We offer systems engineering, modeling & analyses, integration & test, verification, mission formulation and architecture and other services to NASA and commercial customers. These services span a complete integrated analysis suite including structural, thermal, electromagnetic, optical, deployables and other tools to optimize both system and mission design. Integration and test support includes system-level planning, coupled with personnel to assist or observe test flows and ensure proper verification of requirements. Hardware and services are typically provided on a per-project basis using Time and Materials, Cost-Plus, or Fixed Price contracts with monthly payments, and range in size from $100,000 to over $10 million depending on system complexity, customer requirements, and schedule.

Development and Manufacturing

Hardware development occurs at our main facility in Berkeley, California, with over 20,000 sq ft of facilities including assembly and test areas, R&D labs, clean rooms, and thermal-vacuum test equipment. Heliospace leverages existing relationships with an array of vendors vetted under our internal quality control processes to support hardware construction. Our hardware is generally custom designed to customer specifications and translated to drawings including all dimensional and material details. The manufactured components are then sent out for competitive bid to third-party fabricators, who manufacture the components to the required specifications and deliver them to us. We also purchase some finished components from vendors for assemblies, including release mechanisms, heaters, switches, and other specialty components. These components are then assembled, tested, and delivered fully qualified and ready for flight as a complete end-to-end solution. Heliospace maintains a vendor management system, which includes vendor surveys and an approved vendor list with specific approval criteria. A quality assurance process is in place for all components we receive, including inspections, paperwork requirements documenting the origin and authenticity of raw materials used, inspection reports, and other evidence that all incoming components meet the specification requirements and applicable regulations. We try to maintain multiple sources for the same component or material in order to have qualified, alternate sources of supply if our primary source is delayed or does not meet our specifications or quality standards.

Raw Materials and Suppliers

Heliospace engages in manufacturing activities at the piece-part and component level, and thus does not maintain an inventory of raw materials. Therefore, we have limited direct exposure to fluctuations in the supply of raw materials. Most of the value we provide with respect to our hardware comes from our design, engineering, assembly and test activities. While some of the components in our hardware require relatively scarce raw materials, our third-party fabricators have historically not experienced difficulty in procuring those materials.

Examples of our Space Qualified Hardware

Deployable radar antennas on the NASA Europa Clipper mission, which will probe the subsurface of Europa

Low-cost antennas for the NASA SunRISE CubeSat constellation

Deployable sensors and mechanisms for use on three lunar landers as part of the NASA Commercial Lunar Payload Services program

After expanding our market into the commercial realm in 2023, in 2025 we provided an antenna calibration system for a lunar orbiter being built by Firefly Aerospace.

Prototype mechanisms for the Mars Sample Return program

Heliospace Hardware Projects

Examples of our services include systems engineering, integration, test and operations support for large space-based observatories including the James Webb Space Telescope, Roman Space Telescope, and the Habitable Worlds Observatory.

Space Based Energy Solutions

Our Competitive Advantages

We believe that we have few direct competitors of similar size and capabilities that provide the breadth of products, solutions, and expertise that we offer our customers. Given the market fragmentation, we face competition from different competitors across individual products and applications. Competition within our product offerings range from divisions of large corporations who are challenged by cost control and inflexibility, to small, privately held companies with singular capabilities that lack the infrastructure and capacity to scale. System-level, mission focused engineering combined with deep expertise in the production of space qualified hardware is what we believe will enable Heliospace to effectively scale from current offerings to comprehensive solutions for existing and new customers.

Our competitive advantages include the following:

Company Growth Strategy

Our company growth strategy is to continue to build upon our successful flight hardware and services business, which provides a source of recurring revenue, to expand into providing an emerging new source of energy for humanity: Space Based Solar Power (SBSP).

For the hardware and services business, strong team experience in systems for lunar science and exploration makes Helio particularly well positioned to participate in NASA’s rapidly expanding lunar program. Additional opportunities in NASA science programs for planetary and astrophysics missions are coming into the company, and we anticipate additional work in these areas as the NASA science budget solidifies in FY 2027. Our 100% success rate in NASA Phase I to Phase II Small Business Innovation Research awards is supporting the development of several aerospace product lines that can be sold in quantity at predictable margins. In these pursuits the team reputation and network at the various NASA centers and related organizations figures prominently in the generation of new opportunities. Additional capital will support greater outreach and more effective business development along with startup capital to capture larger contracts to address system level as well as hardware/product level solutions.

Our foundational experience in space flight hardware and mission systems will support new revenue generating applications in space. Helio is uniquely positions to offer SBSP solutions with a demonstrated track record of flight hardware and both engineers and solar physicists on staff. The global demand for electricity has been increasing substantially. In the United States, projections are rapidly accelerating due to data center growth, domestic industrial expansion, and increasing electrification of overall energy use (U.S. Energy Information Administration, 2025; Inner City Fund (ICF) 2025). To meet this accelerated demand, significant expansion of both fossil fuel based and clean sources of energy are forecasted. The growing possibility of a supply/demand imbalance results in a projected cost of electricity that exceeds the rate of inflation, impacting residential, commercial, and industrial users.

To meet projected demand in the U.S. and globally, new utility-scale power generation will be required. Meeting this demand using clean renewable energy sources remains a challenge, as these have historically been unable to provide baseload capacity – i.e., the ability to provide reliable, constant energy over long periods. Globally, ground-based solar and wind are projected to expand, but have significant variability and low utilization, and are unable to provide baseload capacity. Energy storage to increase reliability and peak capacity are forecast to have an increasing role, but are resource intensive and difficult to deploy at the required scale. Natural gas is increasingly forecast to meet demand due to cost effectiveness and baseload capability, but remains a non-renewable source with environmental impact, and is subject to price volatility. Nuclear energy faces significant challenges in cost of energy, site selection, availability of fuel, vulnerability to natural disasters, and public perception. The problem of energy available is significant: individual large users (i.e., data centers) are increasingly developing their own behind-the-meter sources. Meanwhile for residential customers, electricity prices will increase at a rate faster than inflation, effectively doubling by 2050.

Space Based Solar Power (SBSP) leverages our best source of energy – our Sun, a giant fusion reactor that will last billions of years. Solar energy in space is abundant, efficient, scalable and constant – a clean source of energy that can provide baseload capability, displacing the role of coal and natural gas and other carbon emitting sources. Falling launch costs combined with advancements in space systems are bringing use of SBSP within the realm of economic feasibility. Using our experience and in-house intellectual property Helio plans to offer a modular, scalable SBSP plant based on HelioSat, our advanced deployable system that expands into large solar collection areas from small spacecraft.

The global market opportunity for electricity supply is substantial, nearly $2 trillion in 2025, expanding to $3.7 trillion by 2035. By 2050 global consumption is predicted to double. Within this is a potential fourfold increase forecast to be from clean/renewable sources. A clean renewable source such as SBSP can provide baseload capability to this growing market at a Levelized Cost of Energy (LCOE) of $0.10/kWh over a lifetime of 20 years. Expansion of this system to 100 GW capability yields $811B lifetime profit and an IRR at 11% annually. Helio plans to demonstrate an initial in-space SBSP system by 2030, followed by larger capacity in the following decade. In parallel with this development, the current hardware and services capabilities will continue to expand as well, leveraging the advances we achieve in SBSP for use in adjacent applications for civil, commercial, and defense related use.

Our Challenges

Notwithstanding the foregoing, we operate in a very competitive and rapidly changing environment. While we believe our competitive strengths will contribute to the growth and success of our company, our business is subject to challenges and uncertainties that may prevent us from achieving our business objectives or otherwise adversely affect our business, results of operations or financial condition.

Among the challenges we face in implementing our growth strategy is the need to be agile in answering the needs of emerging new applications such as SBSP, including through successful innovation and continued refinement both of current and newly developed technologies, products, and services. Developing future innovations and satisfying or responding to changing customer demands and industry cycles safely and in a timely and cost-effective manner will require significant capital, and require us to overcome technological hurdles and navigate highly regulated environments. These will be ongoing challenges for our business.

While our growth strategy is achieving an increasing market share from private and commercial customers, a significant amount of our current revenue relies on U.S. government contracts. The changing political landscape, including the new Executive and Congressional leadership and priorities, the increasing U.S. budget deficit and national debt, and disruptions in the U.S. government budget process, impacts our inability to secure additional U.S. government contracts and represents a continuing challenge to our ability to implement our growth strategy.

Investment Highlights

Implications of Being an Emerging Growth Company and Smaller Reporting Company

The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to avail itself of this exemption from new or revised accounting standards and, therefore, will not be subject to the same new or revised accounting standards as public companies that are not emerging growth companies.

For so long as we are an emerging growth company, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. These include, but are not limited to:

The Company will cease to be an emerging growth company upon the earliest of: (i) the last day of the fiscal year in which the Company has total annual gross revenues of $1.235 billion or more; (ii) the last day of the fiscal year following the fifth anniversary of the Company’s first sale of common equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended; (iii) the date on which the Company has issued more than $1.0 billion in non-convertible debt during the previous three-year period; or (iv) the date on which the Company becomes a “large accelerated filer,” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended.

In addition, Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the “Securities Act”), for complying with new or revised accounting standards. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies.

We are also a “smaller reporting company,” as such term is defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). To the extent that we continue to qualify as a smaller reporting company after we cease to qualify as an emerging growth company, certain of the exemptions available to us as an emerging growth company may continue to be available to us as a smaller reporting company, including: (i) not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act; (ii) scaled executive compensation disclosures; and (iii) the requirement to provide only two years of audited financial statements, instead of three years.

Intellectual Property and Protection

The Company has certain proprietary products and processes which are maintained as trade secrets. The Company has no filed or registered copyrights, trademarks, or patents. Work on government contracts is generally conducted under the Federal Acquisition Regulation (FAR) rights in data clause, for which we claim limited rights to key technologies on a case-by-case basis. For non-government contracts, proprietary products are protected by non-disclosure agreements, and allocation of rights agreements as appropriate. In addition, each employee signs a proprietary information and inventions agreement. In general, critical details of proprietary products are withheld from release in customer interactions based on the judgment of company leadership.

Seasonality in Our Business

We do not believe our business is subject to significant seasonal variation.

Government Regulation

Our business is subject to a wide range of laws and regulations at the federal, state, and local levels, including employment, health care and safety, privacy, data security, environmental, and other requirements. Compliance with these laws and regulations requires management by the Company, including legal assistance, use of professional employment organizations, and other resources on an ongoing basis. Changes in laws and regulations, and their variations in local jurisdictions, require monitoring and research in order to ensure compliance and obtain the appropriate licenses, certificates, permits, and other documentation necessary to conduct business. Many of these laws and regulations are typical of most business activities, whereas we describe additional regulations at the federal level specific to our Company below.

We currently hold and will continue to pursue contracts with NASA and other U.S. government agencies and will thus be subject to FAR. U.S. government contracts require specialized accounting procedures involving direct and indirect cost, and with fee amounts limited by government or agency policies. Government contracts require both financial and compliance audits that may result in the recovery of funds after expenditure and other cost adjustments. Additional scrutiny may result in additional audits and reviews, triggered by technical or programmatic failures or other events. Gross violations of these policies can result in administrative sanctions such as suspension or debarment from doing business with the U.S. government, or civil and criminal penalties. Contracts subject to the Federal Civil False Claims Act include provisions allowing individuals such as employees to file claims on behalf of the U.S. government for contract violations and other unlawful activities. In addition, working with the U.S. government requires disclosure of certain company information, and mandatory labor, non-discrimination, and environmental compliance, among many other requirements. These aspects of the U.S. government regulation of contracts increase the overhead costs associated with contract compliance and add additional risks in conducting these transactions, while the limited fee structure allowed may limit profit under these contracts.

International space law dictates that all commercial activities in space must obtain the authorization and ongoing supervision of a state, which typically takes the form of a license, and all U.S. space companies are therefore subject to U.S. space policies and regulations. The licenses, approvals, and legality of these activities will vary with customers and applications and evolve over time as political bodies and other stakeholders influence the space law framework. The legal framework of each new contract involving activities in space needs to be individually evaluated. Significant ongoing regulations in this context include the protection and oversight of any transfer of hardware or technology to foreign entities, as governed by the International Traffic and Arms Regulations (ITAR) or the U.S. Department of Commerce. U.S. space companies are responsible for ensuring that foreign persons or entities do not have access to applicable technology under ITAR without obtaining an approved government license. ITAR compliance requires registration with the Directorate of Defense Trade Controls (DDTC), followed by generation and submission of ITAR-compliant export licenses. Protection of data subject to ITAR requires employee training and cybersecurity measures. The Company believes these efforts can collectively cost tens of thousands of dollars in fees and personnel costs, but has not incurred any material costs related to ITAR registration to date. For technology not subject to ITAR, shipment or transfer of space technology to foreign entities must obtain a license under the U.S. Department of Commerce. Significant resources can be required to assess and manage these processes to avoid civil or criminal liability. Obligations required under these regulations include registration with the Directorate of Defense Trade Controls (DDTC) and familiarization with the classification of commodities according to Export Administration Regulations (EAR). Ongoing monitoring of changes in export control laws is an important activity that must be maintained to ensure compliance. Additional obligations include the acknowledgment and proper management of customer-supplied technology or information subject to ITAR or EAR.

Employees

As of October 16, 2026, we had approximately 12 employees, 10 of whom were hourly ranging from full to part time, and an additional three personnel under consultant agreements. Most of our full-time employees are highly trained, primarily in the areas of mechanical, structural, and systems engineering and thermal analysis. We are not party to any collective bargaining agreements. Our employees are critical to our long-term success and essential to helping us meet our goals. It is crucial that we continue to attract, retain and motivate exceptional and high-performing employees. To that end, we provide competitive salaries, paid time off, compensatory time and employee stock options.

Litigation

On August 19, 2026, the Company filed an action in the Circuit Court for the Thirteenth Judicial Circuit in and for Hillsborough County, Florida against Joseph T. Pitman, a former co-founder and stockholder of the Company, and ClearTrust, LLC, the Company's transfer agent, concerning the applicability of certain contractual restrictions to shares of the Company's common stock held by Mr. Pitman. The Company seeks declaratory and injunctive relief concerning the transfer of those shares and removal of the restrictive legend applicable to them. On September 3, 2026, the court granted the Company's motion for a temporary injunction, prohibiting Mr. Pitman from transferring the shares and prohibiting ClearTrust, LLC from removing the restrictive legend or facilitating a transfer, pending further order of the court. The action remains pending, and its ultimate outcome cannot presently be determined.

Property

The Company leases its current manufacturing and office facility, located at 2448 Sixth Street, Berkeley, CA 94710. The leased square footage is 20,000 square feet, for $38,192 per month plus expenses. The lease commenced on June 1, 2022 and has an initial term of five years. The Company believes the facility is adequate for its current operations.

Corporate Governance

Board Leadership

The Board is currently chaired by Edward M. Cabrera, who also serves as our Chief Executive Officer.

Director Independence

The Company is not currently listed on a national securities exchange and, as a result, is not subject to the director independence requirements of any such exchange.

The Nasdaq Marketplace Rules require a majority of a listed company’s Board of Directors to be comprised of independent directors within one year of listing. In addition, the Nasdaq Marketplace Rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act.

Under Rule 5605(a)(2) of the Nasdaq Marketplace Rules, a director will only qualify as an “independent director” if, in the opinion of our Board of Directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 of the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the Board of Directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries.

Our Board of Directors has reviewed the composition of our Board of Directors and its committees and the independence of each director. Based upon information requested from and provided by each director concerning his background, employment and affiliations, including family relationships, the Board has determined that Bruce T. Campbell, Vikas Parti, and Mario Noel Martinez each qualify as independent directors as defined under Rule 5605(a)(2) of the Nasdaq Marketplace Rules.

Board Committees

Audit Committee. The Audit Committee consists of Mario Noel Martinez (Chair), Bruce T. Campbell, and Vikas Parti. Each member of the Audit Committee qualifies as an independent director under the corporate governance standards of the Nasdaq Capital Market and the independence requirements of Rule 10A-3 of the Exchange Act. The Board has determined that Mario Noel Martinez qualifies as an “audit committee financial expert” as defined in Item 407(d)(5) of Regulation S-K.

The Audit Committee’s duties are to recommend to our board of directors the engagement of independent auditors to audit our financial statements and to review its accounting and auditing principles. The Audit Committee will review the scope, timing and fees for the annual audit and the results of audit examinations performed by the internal auditors and independent public accountants, including their recommendations to improve the system of accounting and internal controls. The Audit Committee will at all times be composed exclusively of directors who are, in the opinion of our board of directors, free from any relationship which would interfere with the exercise of independent judgment as a committee member and who possess an understanding of financial statements and generally accepted accounting principles. The Board will adopt a written charter for the Audit Committee prior to the effective date of this registration statement.

Compensation Committee. The Compensation Committee consists of Bruce T. Campbell (Chair), Mario Noel Martinez, and Vikas Parti. The Compensation Committee is responsible for oversight of executive and director compensation, incentive compensation plans, and executive succession planning. The Board will adopt a written charter for the Compensation Committee prior to the effective date of this registration statement.

Intellectual Property Committee. The Intellectual Property Committee consists of Vikas Parti, Chair. The Committee oversees the Company’s intellectual property strategy, including patent portfolio development, prosecution, and protection of proprietary technologies.

Code of Ethics and Insider Trading Policy

Our Board of Directors has adopted a Code of Ethics and Business Conduct, effective June 1, 2026, applicable to all of our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer, which is intended to serve as our code of ethics for purposes of Item 406 of Regulation S-K and our code of conduct for purposes of Nasdaq Rule 5610. Our Board of Directors has also adopted an Insider Trading Policy, effective October 16, 2026, which applies to our directors, officers and employees and certain related persons and entities, prohibits trading while aware of material nonpublic information, requires pre-clearance of trades by our Chief Executive Officer, and prohibits short sales, hedging and derivative transactions, margin accounts and pledges involving our securities. The Code of Ethics and the Insider Trading Policy are filed as Exhibits 14.1 and 99.1, respectively, to the registration statement of which this prospectus forms a part, and the Code of Ethics will be posted on our website at https://helio.space/. Any amendments to the Code of Ethics or waivers of its requirements will be disclosed in accordance with applicable SEC and Nasdaq rules.

COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS

The following table sets forth information concerning the compensation earned during the fiscal years ended October 31, 2025 and 2024 by the Company’s named executive officers. Gregory T.

Summary Compensation Table

Emerging Growth Company Status

The conversion price of $10.9225 per share was calculated using the 20-day volume-weighted average price (VWAP) of the Company’s common stock as reported by OTC Markets Group. The shares were issued in reliance on Section 3(a)(9) of the Securities Act. This transaction is described further under “Certain Relationships and Related Party Transactions.”

Employment Agreement with Edward Cabrera (Chief Executive Officer)

In January 2026, the Company entered into an employment agreement with Edward Cabrera, pursuant to which Mr. Cabrera was appointed Chief Executive Officer and Chairman of the Board. The agreement has an initial term of one year and automatically renews for successive one-year terms unless terminated in accordance with its terms.

Under the agreement, the Company issued Mr. Cabrera 600,000 shares of the Company’s common stock upon execution of the agreement, with a grant date fair value of $1,349,700 (approximately $2.25 per share based on the closing price of our common stock on the date of grant). Mr. Cabrera is entitled to receive a nominal annual salary of $1, with any future cash compensation subject to determination by the Company’s Board of Directors based on performance or other criteria.

The agreement provides that Mr. Cabrera may be terminated for cause, resigned voluntarily, or terminated without cause, in each case subject to the terms of the agreement.

Investors should note that if the net proceeds from this offering, combined with prior and concurrent financing activities, equal or exceed $10 million in the aggregate, Mr. Knauf’s cash salary entitlement will be triggered and will become a recurring cash operating expense of the Company.

Retirement Benefits

We do not have a defined benefit pension plan or nonqualified deferred compensation plan. Heliospace provided a retirement plan through July 2025 intended to provide benefits under Section 401(k) of the Code (as defined below), pursuant to which employees, including the Named Executive Officers, can make or have made voluntary pre-tax contributions. Heliospace provided matching contributions to all eligible employees, including our Named Executive Officers. All contributions under the plan are subject to certain annual dollar limitations, which are periodically adjusted for changes in the cost of living.

Equity Incentive Plans

2018 Heliospace Corporation Equity Incentive Plan

The 2018 Equity Incentive Plan (the “2018 Plan”) was originally adopted by Heliospace Corporation’s Board of Directors and approved by its stockholders on July 1, 2018, and was assumed by Helio Corporation as the Company’s equity incentive plan in connection with the Business Combination effective January 3, 2024. The 2018 Plan was amended by the Company’s Board of Directors on December 17, 2023. The 2018 Plan has a stated termination date of July 1, 2028; however, the Company adopted the 2025 Equity Incentive Plan (described below) as its active plan for new equity grants on August 19, 2025. No new equity grants will be made under the 2018 Plan. All outstanding awards previously granted under the 2018 Plan remain governed by the 2018 Plan and the applicable award agreements. As of the date of this prospectus, all outstanding options under the 2018 Plan are fully vested; there are no unvested awards remaining under the 2018 Plan.

Share Reserve. The 2018 Plan authorized the issuance of up to 564,706 shares of Heliospace common stock (adjusted to 476,470 shares following the recapitalization in connection with the Business Combination), in each case as adjusted to give effect to the 1-for-5 Reverse Stock Split, subject to adjustment for stock splits, recapitalizations, and similar events. Shares subject to awards that expire, terminate, or are cancelled without being exercised revert to the share reserve and become available for future issuance under the 2018 Plan.

Eligibility. Incentive Stock Options (ISOs) may be granted only to employees. All other equity incentives - including Nonstatutory Stock Options (NSOs), Restricted Stock Awards, and Stock Appreciation Rights - may be granted to employees, officers, directors, and consultants.

Types of Awards. The 2018 Plan authorized grants of (i) ISOs and NSOs, (ii) Restricted Stock Awards (including stock bonuses), and (iii) Stock Appreciation Rights.

Option Terms. Options have a maximum term of ten (10) years from the date of grant (five (5) years for ISOs granted to Ten Percent Stockholders). The exercise price per share may not be less than 100% of fair market value on the date of grant (110% for ISOs granted to Ten Percent Stockholders). The exercise price may be paid in cash, by delivery of previously owned shares, through a net exercise arrangement, by promissory note, or other lawful consideration approved by the Board. Vesting schedules are determined by the Board on a grant-by-grant basis. Upon termination of continuous service, vested options generally remain exercisable for three months (twelve months in the case of death or disability), subject to the earlier expiration of the option term.

Vesting. The Company granted options under the 2018 Plan with vesting over a period of four years with a one-year cliff, after which 25% of the award vests, followed by 1/48^th per month thereafter. Certain options were granted outright with no vesting period.

Adjustments and Corporate Transactions. The 2018 Plan provides for equitable adjustments to the share reserve and outstanding awards in the event of stock splits, dividends, recapitalizations, and similar events. In connection with a Corporate Transaction (including a Change of Control), the Board may, among other actions, arrange for assumption or substitution of awards, accelerate vesting, or cancel awards in exchange for cash or other consideration.

Administration. The 2018 Plan is administered by the Board, which may delegate administration to a committee. All Board determinations under the 2018 Plan are final, binding, and conclusive.

Arbitration. Disputes relating to awards or the 2018 Plan are to be resolved through binding and confidential arbitration under the Commercial Arbitration Rules of the American Arbitration Association in Denver, Colorado, with arbitration fees paid by the Company.

Governing Law. The 2018 Plan is governed by the laws of the State of Delaware.

Helio Corporation 2025 Equity Incentive Plan

On August 19, 2025, the Company adopted the Helio Corporation 2025 Equity Incentive Plan (the “2025 Plan”), which was also approved by the Company’s stockholders on August 19, 2025. The 2025 Plan is intended to assist the Company in recruiting and retaining employees, officers, directors, and consultants, and to provide incentives tied to increases in the value of the Company’s equity. Unless terminated earlier by the Board, the 2025 Plan will terminate on August 19, 2035, and no awards may be granted after that date.

Administration. The 2025 Plan is administered by the Company’s Board of Directors (the “Board”), unless and until the Board delegates administration to a committee of one or more Board members. Subject to the terms of the 2025 Plan, the administrator has broad discretion to determine eligible participants, the type of award granted, the number of shares subject to awards, vesting schedules, exercise prices (if applicable), and other terms and conditions, and to interpret and administer the 2025 Plan and award agreements. The 2025 Plan permits certain actions that may be treated as “repricing,” including reductions in option exercise prices and cancellation and replacement of options, subject to the consent of adversely affected optionholders and the other limitations set forth in the 2025 Plan.

Shares available for issuance. In connection with the 1-for-5 Reverse Stock Split, the share reserve under the 2025 Plan was automatically adjusted from 2,250,000 shares to 450,000 shares of the Company’s common stock. Effective August 4, 2026, the Board amended the 2025 Plan to further reduce the maximum number of shares of the Company’s common stock that may be issued pursuant to awards under the 2025 Plan to 300,000 shares (post-split), subject to adjustment for stock splits, recapitalizations, and similar events, and to eliminate the automatic annual (“evergreen”) increase to the share reserve. The share reserve under the 2025 Plan is not subject to any automatic, annual or other evergreen increase. Shares generally return to the reserve if awards expire, terminate, are forfeited, or are repurchased by the Company in accordance with the terms of the 2025 Plan.

Eligibility. Incentive stock options may be granted only to employees. Other awards may be granted to employees, officers, directors, and consultants. The 2025 Plan also contains limitations applicable to “ten percent stockholders,” including a higher minimum exercise price and a shorter maximum term for incentive stock options.

Types of awards. The 2025 Plan authorizes the grant of a variety of equity-based awards, including:

Option terms. Options generally may not have a term longer than 10 years from the grant date (or 5 years for incentive stock options granted to ten percent stockholders). The exercise price per share generally may not be less than 100% of fair market value on the grant date (or 110% for incentive stock options granted to ten percent stockholders). The 2025 Plan permits several methods of paying the exercise price, including cash, delivery of previously owned shares (subject to holding period requirements in certain cases), deferred payment arrangements (subject to limitations), “net exercise” arrangements, promissory notes with full recourse, or other lawful consideration acceptable to the Board. Options typically terminate following cessation of service, subject to post-termination exercise periods that vary based on the reason for termination (including death or disability) and the terms of the applicable award agreement.

Restricted stock and other awards. Restricted stock awards may be subject to vesting conditions and may include Company repurchase rights with respect to unvested shares, subject to limitations under the 2025 Plan. Restricted stock units represent the right to receive one share of common stock (or the value thereof in cash) upon vesting and settlement. Stock appreciation rights provide the right to receive the appreciation in the Company’s common stock (in shares, cash, or a combination), as determined by the administrator.

Adjustments and corporate transactions. The 2025 Plan provides for equitable adjustments to the share reserve and outstanding awards in the event of stock splits, dividends, recapitalizations and similar events. In connection with a corporate transaction (including a change of control), the administrator may take a variety of actions with respect to outstanding awards, including assumption or substitution of awards, acceleration of vesting or exercisability, cancellation in exchange for cash or other consideration (which may be zero in certain circumstances), and other actions permitted by the 2025 Plan.

Withholding and other provisions. Award agreements generally require participants to satisfy applicable tax withholding obligations, including through share withholding, cash payment, or other permitted methods. The 2025 Plan includes provisions intended to support compliance with Section 409A of the Internal Revenue Code and provides that awards are subject to any clawback or recoupment policies adopted by the Company and applicable law, including Exchange Act Rule 10D-1 requirements and any applicable listing standards. The 2025 Plan is governed by Florida law.

Arbitration. The 2025 Plan provides that disputes relating to awards or the 2025 Plan are to be resolved through binding and confidential arbitration under the Commercial Arbitration Rules of the American Arbitration Association in Berkeley, California, with arbitration fees paid by the Company, and permits the arbitrator to award attorneys’ fees and costs to the prevailing party.

Indemnification of Officers and Directors

Our Bylaws include provisions that provide for indemnification, expense advancement, and reimbursement for our directors and officers, to the maximum extent allowable under Florida law. We have also entered into or will enter into prior to the effective date of the registration statement of which prospectus forms a part into customary indemnification agreements with our officers or directors. We also currently maintain directors’ and officers’ insurance covering certain liabilities that may be incurred by directors and officers in the performance of their duties.

Policies and Procedures for the Review, Approval or Ratification of Related Person Transactions

On June 1, 2026, our Board approved a written Policy and Procedures with Respect to Related Party Transactions (the “Related Party Transaction Policy”), which is filed as Exhibit 99.2 to the registration statement of which this prospectus forms a part. Prior to that date, the Company did not have a written policy governing the review, approval or ratification of transactions with related persons, and the transactions described above that were entered into prior to that date were not reviewed under the Related Party Transaction Policy.] [ALTERNATIVE B: The Company does not currently have a written policy governing the review, approval or ratification of transactions with related persons. The Company intends to adopt a written Related Party Transaction Policy, substantially in the form filed as Exhibit 99.2 to the registration statement of which this prospectus forms a part, prior to the effective date of this registration statement.]

Prior to the adoption of the Related Party Transaction Policy, related person transactions were reviewed and approved by the Company’s Board of Directors, or by the Audit Committee Chair, as applicable, prior to entry into such transactions, or, if not approved in advance, were submitted for ratification. In reviewing and approving any related person transaction, the Board of Directors or the Audit Committee Chair considered the relevant facts and circumstances, including the nature of the related person’s interest in the transaction, the material terms of the transaction, the purpose of the transaction, the availability of alternative arrangements with unrelated third parties, and whether the transaction was on terms that were no less favorable to the Company than those that could be obtained in an arm’s-length transaction with an unrelated third party.

Any director or officer who had an interest in a related person transaction was required to recuse himself or herself from the deliberations and approval of such transaction.

Under the Related Party Transaction Policy, a “Related Party Transaction” is any transaction, arrangement or relationship in which the Company is a participant, the amount involved exceeds $120,000, and a Related Party (including directors, director nominees, named executive officers, holders of more than 5% of any class of our voting securities, their immediate family members and certain affiliated entities) has a direct or indirect material interest, including the hiring of an immediate family member of a director, named executive officer or more than 5% beneficial owner. The Related Party or the responsible business leader must give notice of a proposed transaction to our Chief Financial Officer, who determines whether it is a Related Party Transaction. If so, the transaction is submitted to the Audit Committee or, where waiting for the next meeting is impracticable, to the Audit Committee Chair, who will consider the relevant facts and circumstances, including the benefits to the Company, the impact on director independence, the availability of comparable products or services, and the terms available to unrelated third parties or employees generally. Only transactions that are in, or are not inconsistent with, the best interests of the Company and its stockholders may be approved, and no member of the Audit Committee may participate in the review of a transaction in which he or she or an immediate family member is the Related Party. Transactions that were not previously approved are submitted for ratification, amendment, termination or rescission. The policy also requires annual questionnaires and certifications from directors, director nominees and executive officers.

DESCRIPTION OF SECURITIES

Common Stock

General. The holders of our Common Stock currently have (a) equal ratable rights to dividends from funds legally available therefore, when, as and if declared by our board of directors; (b) are entitled to share ratably in all of our assets available for distribution to holders of Common Stock upon liquidation, dissolution or winding up of the affairs of the Company; (c) do not have preemptive, subscriptive, or conversion rights and there are no redemption or sinking fund provisions or rights applicable thereto; and (d) are entitled to one non-cumulative vote per share on all matters on which shareholders may vote. Our Bylaws provide that, at all meetings of the shareholders for the election of directors, a plurality of the votes cast shall be sufficient to elect any director. On all other matters, except as otherwise required by Florida law or our Articles of Incorporation, as amended, a majority of the votes cast at a meeting of the shareholders shall be necessary to authorize any corporate action to be taken by vote of the shareholders at such meeting. Our Bylaws and the FBCA provide for written action by consent of the majority of the shareholders without a meeting.

Non-cumulative Voting. Holders of shares of our Common Stock do not have cumulative voting rights, which means that the holders of more than 50% of the outstanding shares, voting for the election of directors, can elect all of the directors to be elected, if they so choose and, in such event, the holders of the remaining shares will not be able to elect any of our directors.

Pre-emptive Rights. As of the date of this Prospectus, no holder of any shares of our capital stock has pre-emptive or preferential rights to acquire or subscribe for any unissued shares of any class of our capital stock not otherwise disclosed herein.

Dilution and Senior Securities

Holders of our Common Stock are subject to significant dilution risk from outstanding convertible instruments and equity awards. As of the date of this prospectus, the following instruments are convertible into or exercisable for shares of our Common Stock and could result in substantial dilution to investors purchasing shares in this offering: (i) outstanding convertible promissory notes issued to CFI Capital LLC, GS Capital Partners, LLC, and Quick Capital, LLC in February 2026 for aggregate gross proceeds of approximately $760,272; (ii) 575,000 shares of Series A Convertible Preferred Stock convertible into shares of Common Stock at a variable conversion price equal to 65% of the lowest trading price during the 10 trading days preceding conversion; (iii) 355,000 shares of Series B Convertible Preferred Stock convertible into shares of Common Stock at a conversion price to be determined in accordance with the Certificate of Designation; (iv) 200,000 shares of Series C Convertible Preferred Stock convertible into shares of Common Stock at a variable conversion price equal to 65% of the lowest trading price during the 10 trading days preceding conversion; (v) 250,000 shares of Series D Convertible Preferred Stock convertible into shares of Common Stock; (vi) 89,168 stock options outstanding under the Company’s equity incentive plans (post-split); and (vii) the Representative Warrants to be issued in connection with this offering. The FirstFire Warrant (originally exercisable for 66,000 shares) was exercised in full via cashless exercise on March 12, 2026, resulting in the issuance of 52,640 shares of Common Stock, and no FirstFire Warrant remains outstanding. Additionally, the Series A, Series B and Series C Convertible Preferred Stock each have a liquidation preference that is senior to the Common Stock upon any liquidation, dissolution, or winding up of the Company, although each of the Series C and Series D Preferred Stock ranks junior to the Company’s other outstanding preferred stock and to its indebtedness. See “Description of Securities — Preferred Stock” and “Risk Factors — You may experience significant dilution from the conversion of outstanding convertible instruments” and “Dilution” for additional information.

Representative Warrants

In connection with and on the closing date of this offering, we will issue to the Representative certain warrants (the “Representative Warrants”) to purchase up to 5% of the shares of our Common Stock sold in the offering, at an exercise price equal to 110% of the public offering price per share. The Representative Warrants provide for a cashless exercise right, are non-exercisable for a period of six months following the closing date of this offering, and expire five years after the closing date. The Representative Warrants shall not be redeemable. The Representative Warrants will contain provisions for one demand registration of the sale of the underlying shares of Common Stock at the Company’s expense, an additional demand registration at the warrant holders’ expense, and unlimited “piggyback” registration rights for a period of five years after the closing at the Company’s expense. The Representative Warrants and the underlying shares have been deemed compensation by FINRA and are therefore subject to FINRA Rule 5110(e)(1) lock-up restrictions for 180 days following the effective date of the registration statement. See “Underwriting — Representative Warrants.”

FirstFire Warrant

In connection with the Securities Purchase Agreement dated January 14, 2026, the Company issued to FirstFire Global Opportunities Fund, LLC a warrant (the “FirstFire Warrant”) to purchase up to 66,000 shares of our common stock (subject to adjustment for anti-dilution events) at an exercise price of $2.50 per share (subject to adjustment). The FirstFire Warrant had a five-year term and was exercisable immediately upon issuance. On March 12, 2026, FirstFire exercised the FirstFire Warrant in full via cashless exercise, resulting in the issuance of 52,640 shares of our common stock. No FirstFire Warrant remains outstanding.

FirstFire Note

The FirstFire Note, in the original principal amount of $165,000, has been fully satisfied and cancelled. In connection with the Securities Purchase Agreement dated January 14, 2026, the Company issued the FirstFire Note to FirstFire with a purchase price of $150,000 reflecting a $15,000 original issue discount. The FirstFire Note bore interest at 10% per annum and was scheduled to mature on January 14, 2027.

The FirstFire Repayment Shares were issued in reliance on Section 3(a)(9) of the Securities Act. The FirstFire Warrant was exercised in full via cashless exercise on March 12, 2026 prior to the satisfaction of the FirstFire Note. No FirstFire Warrant remains outstanding.

Preferred Stock

General. Our board of directors has the authority, without further action by the shareholders, to issue up to 20,000,000 shares of Preferred Stock in one or more series and to fix the designations, powers, preferences, privileges, and relative participating, optional, or special rights as well as the qualifications, limitations, or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, and liquidation preferences, any or all of which may be greater than the rights of the Common Stock. Our board of directors, without shareholder approval, will be able to issue convertible Preferred Stock with voting, conversion, or other rights that could adversely affect the voting power and other rights of the holders of Common Stock. Preferred Stock could be issued quickly with terms calculated to delay or prevent a change of control or make removal of management more difficult. Additionally, the issuance of Preferred Stock may have the effect of decreasing the market price of our Common Stock and may adversely affect the voting and other rights of the holders of Common Stock.

The material terms of the Series C Preferred Stock are as follows: (i) stated value of $1.00 per share; (ii) ranks senior to the Common Stock, and junior to the Company’s existing and outstanding preferred stock (including the Series A, Series B and Series D Preferred Stock) and to all existing and future indebtedness, with respect to dividends and distributions upon liquidation; (iii) cumulative dividends at an annual rate of 10% of the stated value, payable upon redemption, liquidation, or conversion, increasing to 22% upon the occurrence of certain events of default; (iv) beginning 180 days after issuance, convertible into shares of Common Stock at a variable conversion price equal to 65% of the lowest trading price of the Common Stock during the ten trading days preceding the conversion date, subject to adjustment; (v) subject to a 4.99% beneficial ownership conversion limitation that may not be waived; (vi) the Company may redeem the Series C Preferred Stock within 180 days after issuance at redemption premiums ranging from 115% to 125% of the stated value, and, on the earlier of twelve months after issuance or an event of default, may redeem the outstanding shares for cash; and (vii) no voting rights except as required by law and customary protective provisions in favor of the holders. As of the date of this prospectus, 200,000 shares of Series C Convertible Preferred Stock are issued and outstanding, and 1,500,000 shares are designated.

Series D Preferred Stock. On January 13, 2026, the Company designated 250,000 shares of its authorized Preferred Stock as Series D Convertible Preferred Stock pursuant to a Certificate of Designations filed with the Florida Department of State. On that date, the Company issued 250,000 shares of Series D Convertible Preferred Stock to an accredited investor pursuant to a Securities Purchase Agreement, in exchange for the cancellation of a $100,000 promissory note previously held by such investor (conversion price of $0.40 per share). The transaction was made in reliance on the exemption from registration provided by Rule 506(c) of Regulation D. The material terms of the Series D Preferred Stock are as follows: (i) par value of $0.0001 per share and a stated value of $0.40 per share; (ii) ranks senior to the Common Stock, and junior to the Company’s existing and outstanding preferred stock and to all existing and future indebtedness, with respect to dividends and distributions upon liquidation; (iii) cumulative annual dividend equal to 10% of the stated value, payable upon redemption, liquidation, or conversion; (iv) upon any liquidation, dissolution, winding up, or deemed liquidation event, holders are entitled to receive, prior to any distribution to holders of Common Stock, an amount equal to the stated value plus accrued and unpaid dividends and any applicable adjustment amounts; (v) beginning 180 days after issuance, convertible into shares of Common Stock, subject to a beneficial ownership limitation; and (vi) classified as permanent equity. As of the date of this prospectus, 250,000 shares of Series D Convertible Preferred Stock are issued and outstanding.

Other Outstanding Convertible Instruments

In addition to the securities described above, the Company has issued convertible promissory notes and other instruments that are convertible into shares of our common stock and could result in material dilution to investors in this offering. In February 2026, the Company issued convertible or promissory notes to CFI Capital LLC, GS Capital Partners, LLC, and Quick Capital, LLC for aggregate gross proceeds of approximately $760,272. These notes contain conversion, anti-dilution, and default provisions, and certain of these notes include variable rate conversion features. The outstanding principal amount of, and number of shares issuable under, these convertible instruments has changed since issuance as a result of repayments, conversions, and additional financings; as of July 31, 2026, the Company had convertible notes payable outstanding in the aggregate principal amount of $522,222 and notes payable outstanding in the aggregate principal amount of $750,500. Conversion prices among the three notes are as follows: 60% of the lowest trading price as reported by OTC Markets over the previous 20 trading days; 70% of the lowest trading price over the previous 15 trading days; and 65% of the lowest trading price over the previous 10 trading days.

In addition, the Company has outstanding employee stock options (89,168 options, post-split) under the 2018 Equity Incentive Plan and the 2025 Equity Incentive Plan. The 2025 Plan has a maximum aggregate share reserve of 300,000 shares (post-split), and is not subject to any automatic annual increase. Each of these instruments could result in the issuance of additional shares of our common stock and materially dilute the interests of holders of the common stock offered in this offering.

Board of Directors Vacancies

Our Bylaws authorize our board of directors to fill vacant directorships until such time as a new director is elected by the shareholders. Directors may be removed by affirmative vote of the holders of the majority of stock entitled to vote at any meeting of shareholders called expressly for that purpose.

Director Action; Special Meeting of Directors

Our Bylaws provide that the Directors of the Company may take action by unanimous written consent without a meeting. Special meetings of the Board of Directors may be called by the Chairman of the Board of Directors, the Vice Chairman (if any), the Chief Executive Officer, or any two directors.

Shareholder Action; Special Meeting of Shareholders

Our Bylaws and the FBCA provide that the Shareholders of the Company may take written action by consent of the majority of the shareholders without a meeting. Our Bylaws provide that special meetings may be called by the Chairman of the Board of Directors, the Chief Executive Officer, the Chief Operating Officer, a majority of the Board, or upon written demand delivered to the Secretary, signed and dated by the holders of not less than ten percent (10%) of all the votes entitled to be cast on any issue to be considered at the proposed special meeting.

Authorized but Unissued Shares

Our authorized but unissued shares of Common Stock and preferred stock are available for future issuance without shareholder approval and may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions, and employee benefit plans. The existence of authorized but unissued and unreserved Common Stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger, or otherwise.

Dissenters’ Rights of Appraisal and Payment

Under the FBCA with certain exceptions, our stockholders have appraisal rights in connection with a merger or consolidation of us. Pursuant to the FBCA, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Florida circuit court in the applicable county.

Stockholders’ Derivative Actions

Under the FBCA, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Our Amended and Restated Bylaws (“Bylaws”) provide that unless the Company consents in writing to the selection of an alternative forum, the state courts of Florida (or if a state court within the state of Florida does not have jurisdiction the federal courts for the Middle District of Florida) will be the sole and exclusive forum for any and all legal proceedings concerning (a) any derivative action or proceeding brought on behalf of the Company; (b) any action asserting a claim of breach of a fiduciary duty owed by any current or former directors, officers, or other employees of the Company to the Company or the Company’s shareholders; (c) any action arising pursuant to any provision of the FBCA or the Articles of Incorporation or the Bylaws (as either may be amended from time to time); or (d) any other action asserting a claim governed by the internal affairs doctrine.

The state forum provision may not apply to any causes of action arising under the Securities Act or the Exchange Act. There is uncertainty as to whether a court would enforce our exclusive forum provisions related to Securities Act claims. Investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Additionally, Article 8.2 of our Amended and Restated Bylaws provide that unless the Company consents in writing to the selection of an alternative forum, the U.S. federal district courts shall be the exclusive forum for the resolution of any complaint asserting a cause of action against the Company or any director, officer, other employee or agent of the Company arising under the Securities Act of 1933, as amended.

There is uncertainty as to whether a court would enforce our exclusive forum provisions related to Securities Act claims. Investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is ClearTrust, LLC, located at 16540 Pointe Village Drive, Suite 210, Lutz, Florida 33558.

Stock Market Listing

Our common stock is currently quoted on the OTCID under the symbol “HLEO.” In connection with this offering, we have applied to list our common stock on Nasdaq under the symbol “HLEO.” If our listing application is approved, we expect to list our common stock on Nasdaq upon consummation of this offering, at which point our common stock will cease to be traded on the OTCID. There can be no assurance that our common stock will be listed on Nasdaq, and this offering is contingent on such listing being approved by Nasdaq.

Limitations on Liability and Indemnification of Officers and Directors

Florida law authorizes corporations to limit or eliminate (with a few exceptions) the personal liability of directors to corporations and their shareholders for monetary damages for breaches of directors’ fiduciary duties as directors. Our Articles of Incorporation and Bylaws include provisions that eliminate, to the maximum extent allowable under Florida law, the personal liability of directors or officers for monetary damages for actions taken as a director or officer, as the case may be. Our Articles of Incorporation and Bylaws also provide that we must indemnify and advance reasonable expenses to our directors and officers to the fullest extent permitted by Florida law. We are also expressly authorized to carry directors’ and officers’ insurance for our directors, officers, employees and agents for some liabilities. We currently maintain directors’ and officers’ insurance covering certain liabilities that may be incurred by directors and officers in the performance of their duties.

The limitation of liability and indemnification provisions in our Articles of Incorporation and Bylaws may discourage shareholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our shareholders. In addition, your investment may be adversely affected to the extent that, in a class action or direct suit, we pay the costs of settlement and damage awards against directors and officers pursuant to the indemnification provisions in our Articles of Incorporation and Bylaws.

There is currently no pending litigation or proceeding involving any of the directors, officers or employees for which indemnification is sought.

In so far as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

UNDERWRITING

We will enter into an underwriting agreement with R.F. Lafferty & Co., Inc., as the representative of the underwriters (the “Representative”), with respect to the shares sold in this offering. Subject to certain conditions, we have agreed to sell to the underwriters, and each of the underwriters has agreed to purchase the shares listed next to its name in the table at the public offering price per unit less the underwriting discounts set forth on the cover page of this prospectus.

The underwriters have committed to purchase all of the shares offered by us other than those shares covered by the over-allotment option described below, if they purchase any. The obligations of the underwriters may be terminated upon the occurrence of certain events specified in the underwriting agreement. Furthermore, pursuant to the underwriting agreement, the underwriters’ obligations are subject to customary conditions, representations and warranties contained in the underwriting agreement, such as receipt by the underwriters of officers’ certificates and legal opinions.

We have agreed to indemnify the underwriters against specified liabilities, including liabilities under the Securities Act, and to contribute to payments the underwriters may be required to make in respect thereof.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to the approval of legal matters by their counsel and other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Over-Allotment Option

We have granted to the underwriters an option to purchase from us up to an additional 300,000 shares of our common stock, representing 15% of the shares sold in this offering, at the assumed public offering price of $4.50 per share, solely to cover over-allotments, if any. The shares of our common stock to be purchased pursuant to the over-allotment option will be acquired at the initial public offering price, less the underwriting discounts. The underwriters may exercise this option, in whole or in part, any time during the 45-day period after the closing date of the offering, but only to cover over-allotments, if any. To the extent the underwriters exercise the option, the underwriters will become obligated, subject to certain conditions, to purchase the shares for which they exercise the option.

Underwriting Discount, Commissions and Expenses

We estimate that the total expenses of the offering payable by us, excluding underwriting discounts and commissions, will be approximately $376,636. Under the underwriting agreement, we will pay the Representative fees and commissions equal to 7.0% of the gross proceeds raised in the offering. The following table shows the per share price and total underwriting discounts and commissions to be paid to the underwriters. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ over-allotment.

The Representative has advised us that it proposes to offer the shares to the public at the public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $[●]. After this offering, the public offering price, concession and reallowance to dealers may be changed by the underwriters. No such change will change the amount of proceeds we receive as set forth on the cover page of this prospectus. The shares are offered by the underwriters as stated herein, subject to receipt and acceptance by it and subject to its right to reject any order in whole or in part. The underwriters have informed us that they do not intend to confirm sales to any accounts over which they exercise discretionary authority.

The following table shows the underwriting discounts payable to the underwriters by us in connection with this offering. Such amounts are shown assuming both no exercise and full exercise of the underwriter’s over-allotment option.

We have agreed to reimburse the Representative of the underwriters out of the proceeds of the offering for accountable legal expenses incurred by the Representative in connection with the offering, including: (a) all filing fees and expenses relating to the registration of the shares offered hereby with the Securities and Exchange Commission and the filing of the offering materials with FINRA; (b) all fees and expenses relating to the listing of the shares on Nasdaq and such other stock exchanges as we and the Representative together determine; (c) all fees, expenses and disbursements relating to background checks of the Company’s officers and directors; (d) all fees, expenses and disbursements relating to the registration or qualification of the shares under “blue sky” or securities laws of such states of the U.S. and other jurisdictions designated by the Representative, including the reasonable fees and expenses of the Representative’s blue sky counsel; (e) all fees and expenses associated with the “road show”; (f) the costs of all mailing and printing of documents relating to the offering; (g) the costs and expenses of a public relations firm; (h) the costs of preparing, printing and delivering certificates representing the shares; (i) fees and expenses of the transfer agent for the shares; (j) transfer and/or stamp taxes, if any, payable upon our transfer of the shares to the underwriters; (k) the fees and expenses of our accountants; (l) the fees and expenses of the Representative’s and our legal counsel and other agents and representatives; (m) the $5,000 cost associated with the Representative’s clearing system data services and communications expenses; and (n) the $10,000 cost associated with the Representative’s Capital IQ system for comparable company analysis and valuation. For the sake of clarity, it is understood and agreed that the Company shall be responsible for the Representative’s legal fees and expenses irrespective of whether the offering is consummated or not and that the maximum amount of legal fees, costs and expenses incurred by the Representative that the Company shall be responsible for shall not exceed $180,000 in the event of a closing of the offering, and shall not exceed $75,000 in the event that there is not a closing of the offering. We have also agreed to pay to the underwriters a non-accountable expense allowance equal to 1% of the gross proceeds of the offering payable at the closing of the offering. 

We paid the expense advance of $25,000 to the Representative, and have agreed to pay $30,000 due upon the initial filing of the registration statement and $10,000 upon receipt of the first round of SEC comments. The advance shall be applied towards reasonable out-of-pocket expenses including legal fees. However, in the event the offering is terminated, the Representative shall return any portion of the advance not used to pay its accountable out-of-pocket expenses actually incurred

No Sales of Similar Securities

We have agreed with the underwriters that not to, without the prior written consent of the Representative, for a period of 12 months after the consummation of this offering, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any classes of our stocks or any securities convertible into or exercisable or exchangeable for classes of our stocks, (ii) file or caused to be filed any registration statement with the SEC, relating to the offering of any classes of our stocks or any securities convertible into or exercisable or exchangeable for any classes of our stocks, (iii) complete any offering of debt securities, other than entering into a line of credit with a traditional bank, or (iv) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any classes of our stocks, whether any such transaction described in clause (i), (ii), (iii) or (iv) above is to be settled by delivery of any classes of our stocks or such other securities, in cash or otherwise.

Lock-Up Agreements

We, each of our officers, directors and executive and 5% or greater affiliated shareholders have agreed, subject to certain exceptions, not to offer, issue, sell, contract to sell, encumber, grant any option for the sale of or otherwise dispose of any shares of our common stock or other securities convertible into or exercisable or exchangeable for our common stock for a period of six (6) months after this offering is completed without the prior written consent of the Representative.

The Representative may in its sole discretion and at any time without notice release some or all of the shares subject to lock-up agreements prior to the expiration of the lock-up period.

Representative’s Warrants

We have agreed to issue to the Representative or its designees at the closing of this offering warrants to purchase the number of shares of common stock equal to 5.0% of the aggregate number of shares sold in this offering. The warrants will be exercisable at any time and from time to time, in whole or in part, during the four-and-a-half-year period commencing six months after the commencement of sales in this offering. The warrants will be exercisable at a per share price equal to 110.0% of the public offering price per share in the offering. The Representative’s Warrants provide for registration rights (including a one-time demand registration right at the expense of the Company, an additional demand registration right at the expense of the warrant holders, and unlimited piggyback registration rights at the expense of the Company, each expiring five years from the closing of the offering) and customary anti-dilution provisions, as permitted by FINRA Rule 5110(g)(8).

The warrants have been deemed compensation by FINRA and are therefore subject to a 180-day lock-up pursuant to FINRA Rule 5110(e)(1) of FINRA. The Representative (or permitted assignees under FINRA Rule 5110(e)(2)) will not sell, transfer, assign, pledge, or hypothecate these warrants or the securities underlying these warrants, nor will they engage in any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the warrants or the underlying securities for a period of 180 days from the date of this prospectus. The warrants and the common stocks underlying the warrants are being registered as a part of the registration statement of which this prospectus forms a part and will be freely tradable upon the declaration of the effectiveness of such registration statement by the SEC.

The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary cash dividend or recapitalization, reorganization, merger or consolidation.

Determination of Offering Price

In determining the initial public offering price, we and the Representative have considered a number of factors, including:

The estimated initial public offering price set forth on the cover page of this preliminary prospectus is subject to change as a result of market conditions and other factors. Neither we nor the Representative can assure investors that an active trading market will develop for our common stock, or that the shares will trade in the public market at or above the initial public offering price.

Tail Financing

If during the period that is twelve (12) months following the closing of this initial public offering, we consummate a financing with investors whom the Representative introduced to us during the period in which we engaged the Representative, we will pay the Representative a fee equal 7.0% of the proceeds of such financing and warrants to purchase a number of shares of our common stock equal to 5.0% of the aggregate number of shares of our common stock sold in such financing at an exercise price equal to 110% of the price of the shares of our common stock sold in such financing, provided that such financing is by an investor actually introduced to us in an offering in which we had direct knowledge of such investor’s participation.

Right of First Refusal

We have granted the Representative the right to act as sole managing underwriter and dealer manager, book runner or sole placement agent for any and all of our future public and private equity, equity-linked, and debt (excluding commercial bank debt) offerings during the twelve (12) month period following the completion of this initial public offering.

Indemnification

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make for these liabilities.

Price Stabilization, Short Positions, and Penalty Bids

In connection with this offering, each underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. Specifically, such underwriter may over-allot in connection with this offering by selling more securities than are set forth on the cover page of this prospectus. This creates a short position in our securities for such underwriter’s own accounts. The short position may be either a covered short position or a naked short position. In a covered short position, the number of securities over-allotted by such underwriter is not greater than the number of securities that it may purchase in the over-allotment option. In a naked short position, the number of securities involved is greater than the number of securities in the over-allotment option. To close out a short position, such underwriter may elect to exercise all or part of the over-allotment option. Such underwriters may also elect to stabilize the price of our securities or reduce any short position by bidding for, and purchasing, securities in the open market.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter or dealer repays selling concessions allowed to it for distributing a security in this offering because the underwriter repurchases that security in stabilizing or short covering transactions.

Finally, each underwriter may bid for, and purchase, shares of our securities in market-making transactions, including “passive” market-making transactions as described below.

These activities may stabilize or maintain the market price of our securities at a price that is higher than the price that might otherwise exist in the absence of these activities. The underwriters are not required to engage in these activities and may discontinue any of these activities at any time without notice. These transactions may be effected on Nasdaq, in the over-the-counter market, or otherwise.

In connection with this offering, the underwriters and selling group members, if any, or their affiliates may engage in passive market-making transactions in our common stock immediately prior to the commencement of sales in this offering, in accordance with Rule 103 of Regulation M under the Exchange Act. Rule 103 generally provides that:

Electronic Distribution

This prospectus in electronic format may be made available on websites or through other online services maintained by the underwriters, or by their affiliates. Other than this prospectus in electronic or printed format, the information on the underwriters’ websites and any information contained on any other websites maintained by an underwriter is not part of this prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or the underwriters in their capacity as underwriters, and should not be relied upon by investors.

Certain Relationships

The Representative and its respective affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. The Representative has received, or may in the future receive, customary fees and commissions for these transactions.

In particular, we may request, as a condition to be offered securities, that Qualified Investors will each represent, warrant and certify to us or to anyone acting on our behalf: (i) that it is an investor falling within one of the categories listed in the First Addendum to the Israeli Securities Law, 5728 - 1968, (ii) which of the categories listed in the First Addendum to the Israeli Securities Law, 5728 - 1968 regarding Qualified Investors is applicable to it, (iii) that it will abide by all provisions set forth in the Israeli Securities Law, 5728 - 1968 and the regulations promulgated thereunder in connection with the offer to be issued securities, (iv) that the securities that it will be issued are, subject to exemptions available under the Israeli Securities Law, 5728 - 1968: (a) for its own account, (b) for investment purposes only, and (c) not issued with a view to resale within the State of Israel, other than in accordance with the provisions of the Israeli Securities Law, 5728 - 1968, and (v) that it is willing to provide further evidence of its Qualified Investor status.

SHARES ELIGIBLE FOR FUTURE SALES

Our common stock is currently quoted on the OTCID under the symbol “HLEO.” In connection with this offering, we have applied to list our common stock on Nasdaq under the symbol “HLEO.” If our listing application is approved, we expect to list our common stock on Nasdaq upon consummation of this offering, at which point our common stock will cease to be traded on the OTCID. There can be no assurance that our common stock will be listed on Nasdaq, and this offering is contingent on such listing being approved by Nasdaq.

Sale of Restricted Shares

All of the shares of Common Stock sold in this offering, including any shares sold upon exercise of the underwriters’ option to purchase additional shares of Common Stock, will be freely tradable in the public market without restriction or further registration under the Securities Act, unless the shares are held by any of our “affiliates” as such term is defined in Rule 144 under the Securities Act, or unless a contractual lockup agreement is entered into. All remaining shares of Common Stock held by existing shareholders immediately prior to the consummation of this offering will be “restricted securities” as such term is defined in Rule 144. These restricted securities were issued and sold by us in private transactions and are eligible for public sale only if registered under the Securities Act or if they qualify for an exemption from registration under the Securities Act, including the exemptions provided by Rule 144 or Rule 701.

Lock-Up Agreements

Our executive officers, directors, and holders of 5% or more of our outstanding Common Stock (and all holders of securities exercisable for or convertible into shares of Common Stock) have agreed to lock-up restrictions for a period of six months following the closing of this offering, subject to customary exceptions and the prior written consent of the Representative. Upon expiration of the applicable lock-up period, a significant number of additional shares may become available for sale in the public market, which could adversely affect the market price of our Common Stock. For a description of the material terms of the lock-up agreements, including permitted exceptions, see “Underwriting - Lock-Up Agreements” beginning on page 79.

Rule 144

In general, under Rule 144, as currently in effect, once we have been subject to the public company reporting requirements of the Exchange Act, for at least 90 days, a person (or persons whose shares are required to be aggregated) who is not deemed to have been one of our “affiliates” for purposes of Rule 144 at any time during the three months preceding a sale and who has beneficially owned restricted securities within the meaning of Rule 144 for at least six months, including the holding period of any prior owner other than one of our “affiliates,” is entitled to sell those shares in the public market (subject to the lock-up agreement referred to below, if applicable) without complying with the manner of sale, volume limitations, or notice provisions of Rule 144, but subject to compliance with the public information requirements of Rule 144. Rule 144(a)(1) defines an “affiliate” of an issuing company as a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such issuer. Directors, officers, and holders of ten percent or more of our voting securities (including securities which are issuable within the next 60 days) are deemed to be affiliates of the issuing company. If such a person has beneficially owned the shares proposed to be sold for at least one year, including the holding period of any prior owner other than “affiliates,” then such person is entitled to sell such shares in the public market without complying with any of the requirements of Rule 144 (subject to the lock-up agreement referred to above, if applicable). In general, under Rule 144, as currently in effect, once we have been subject to the public company reporting requirements of the Exchange Act for at least 90 days, our “affiliates,” as defined in Rule 144, who have beneficially owned the shares proposed to be sold for at least six months, including the holding period of any prior owner other than one of our “affiliates,” are entitled to sell in the public market, upon expiration of any applicable lock-up agreements and within any three-month period, a number of those shares of our Common Stock that does not exceed the greater of:

Such sales under Rule 144 by our “affiliates” or persons selling shares on behalf of our “affiliates” are also subject to certain manner of sale provisions, notice requirements, and to the availability of current public information about us.

The foregoing is a brief summary of the general requirements of Rule 144. You should consult with your own legal and financial advisors regarding the availability of Rule 144 or any other exemptions from the registration requirements of the Securities Act for the resale of any shares of our common stock that you acquired prior to this offering.

Registration Statement on Form S-8

On August 5, 2026, we filed a registration statement on Form S-8 under the Securities Act to register an aggregate of 300,000 shares of our common stock issuable under the Helio Corporation 2025 Equity Incentive Plan, consisting of 77,572 shares subject to outstanding awards and 222,428 shares reserved for future issuance. Shares registered on the Form S-8 generally will be available for sale in the public market upon issuance, subject to any applicable vesting requirements, the lock-up agreements described above, and, in the case of shares held by our affiliates, the volume, manner-of-sale, current public information, and other limitations of Rule 144. The Form S-8 did not include a reoffer prospectus, and shares held by our affiliates may be resold only pursuant to an effective registration statement or an available exemption, including Rule 144.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of certain material U.S. federal income tax consequences of the acquisition, ownership, and disposition of shares of our common stock. This discussion is limited to certain U.S. federal income tax considerations to beneficial owners of our common stock who are initial purchasers of such common stock pursuant to this offering and hold the common stock as a capital asset within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). This discussion assumes that any distributions made by us on our common stock and any consideration received by a holder in consideration for the sale or other disposition of our common stock will be in U.S. dollars.

This summary is based upon U.S. federal income tax laws as of the date of this prospectus, which is subject to change or differing interpretations, possibly with retroactive effect. This discussion is a summary only and does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances, including but not limited to the alternative minimum tax, the Medicare tax on certain net investment income, and the different consequences that may apply if you are subject to special rules that apply to certain types of investors, including but not limited to:

If a partnership (including an entity or arrangement treated as a partnership or other pass-thru entity for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner, member, or other beneficial owner in such partnership will generally depend upon the status of the partner, member, or other beneficial owner, the activities of the partnership, and certain determinations made at the partner, member, or other beneficial owner level. If you are a partner, member, or other beneficial owner of a partnership holding our common stock, you are urged to consult your tax advisor regarding the tax consequences of the acquisition, ownership, and disposition of our common stock.

This discussion is based on the Code and administrative pronouncements, judicial decisions, and final, temporary, and proposed Treasury regulations as of the date hereof, which are subject to change, possibly on a retroactive basis and changes to any of which subsequent to the date of this prospectus may affect the tax consequences described herein. This discussion does not address any aspect of state, local or non-U.S. taxation, or any U.S. federal taxes other than income taxes (such as gift and estate taxes).

We have not sought, and do not expect to seek, a ruling from the U.S. Internal Revenue Service (the “IRS”) as to any U.S. federal income tax consequence described herein. The IRS may disagree with the discussion herein and its determination may be upheld by a court. Moreover, there can be no assurance that future legislation, regulations, administrative rulings or court decisions will not adversely affect the accuracy of the statements in this discussion. You are urged to consult your tax advisor with respect to the application of U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or foreign jurisdiction.

THIS DISCUSSION IS ONLY A SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS ASSOCIATED WITH THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK. EACH PROSPECTIVE INVESTOR IN OUR COMMON STOCK IS URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH INVESTOR OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK, INCLUDING THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL NON-INCOME, STATE, LOCAL and NON-U.S. TAX LAWS.

U.S. Holders

This section applies to you if you are a “U.S. holder.” A U.S. holder is a beneficial owner of our common stock who or that is, for U.S. federal income tax purposes:

Taxation of Distributions

If we pay distributions in cash or other property (other than certain distributions of our stock or rights to acquire our stock) to U.S. holders of shares of our common stock, such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. holder’s adjusted tax basis in our common stock. Any remaining excess will be treated as gain realized on the sale or other disposition of the common stock and will be treated as described under “U.S. Holders — Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Common Stock” below.

Dividends we pay to a U.S. holder that is a taxable corporation generally will qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), and provided certain holding period requirements are met, dividends we pay to a non-corporate U.S. holder may constitute “qualified dividend income” that will be subject to tax at the maximum tax rate accorded to long-term capital gains. If the holding period requirements are not satisfied, then a corporation may not be able to qualify for the dividends received deduction and would have taxable income equal to the entire dividend amount and non-corporate U.S. holders may be subject to tax on such dividend at regular ordinary income tax rates instead of the preferential rate that applies to qualified dividend income.

Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Common Stock

Upon a sale or other taxable disposition of our common stock, a U.S. holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. holder’s adjusted tax basis in the common stock. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. holder’s holding period for the common stock so disposed of exceeds one year. Long-term capital gains recognized by non-corporate U.S. holders may be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

Generally, the amount of gain or loss recognized by a U.S. holder is an amount equal to the difference between (i) the sum of the amount of cash and the fair market value of any property received in such disposition and (ii) the U.S. holder’s adjusted tax basis in its common stock so disposed of. A U.S. holder’s adjusted tax basis in its common stock generally will equal the U.S. holder’s acquisition cost less any prior distributions treated as a return of capital.

Information Reporting and Backup Withholding

In general, information reporting requirements may apply to dividends paid to a U.S. holder and to the proceeds of the sale or other disposition of our common stock, unless the U.S. holder is an exempt recipient. Backup withholding may apply to such payments if the U.S. holder fails to provide a taxpayer identification number, a certification of exempt status, or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our securities.

LEGAL MATTERS

The validity of the securities offered hereby will be passed upon for us by Business Legal Advisors, LLC, Draper, Utah. Certain legal matters relating to this offering will be passed upon for the underwriters by Lucosky Brookman LLP.

EXPERTS

The consolidated financial statements of Helio Corporation as of October 31, 2025 and 2024 and for the years then ended have been included in this prospectus in reliance on the report of Astra Audit & Advisory, LLC, a registered PCAOB firm, appearing elsewhere herein, given on the authority of said firm as experts in auditing and accounting. Astra Audit & Advisory, LLC was dismissed as the Company’s independent registered public accounting firm effective February 21, 2026. The Company has engaged Hacker, Johnson & Smith PA (“HJS”) as its independent registered public accounting firm to audit the Company’s consolidated financial statements for the fiscal year ending October 31, 2026.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

On February 21, 2026, the Company dismissed Astra Audit & Advisory, LLC (“Astra”) as the Company’s independent registered public accounting firm, effective immediately. The decision to dismiss Astra was approved by the Company’s Board of Directors. Astra’s reports on the Company’s consolidated financial statements for each of the two fiscal years ended October 31, 2025 and October 31, 2024 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles, except that each such report contained an explanatory paragraph expressing substantial doubt about the Company’s ability to continue as a going concern. During the fiscal years ended October 31, 2025 and October 31, 2024, and through February 21, 2026, there were no disagreements with Astra on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to Astra’s satisfaction, would have caused Astra to make reference to the subject matter of the disagreement in connection with its reports. During the fiscal years ended October 31, 2025 and October 31, 2024, and through February 21, 2026, there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

On February 21, 2026, the Board of Directors engaged Hacker, Johnson & Smith PA (“HJS”) as the Company’s independent registered public accounting firm to audit the Company’s consolidated financial statements for the fiscal year ending October 31, 2026. During the fiscal years ended October 31, 2025 and October 31, 2024, and the subsequent interim period through February 21, 2026, neither the Company nor anyone acting on its behalf consulted with HJS regarding: (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements; or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Shareholders of Helio Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Helio Corporation (the “Company”) as of October 31, 2025 and 2024, and the related consolidated statements of operations, changes in shareholders’ deficit and cash flows for each of the years in the two-year period ended October 31, 2025, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of October 31, 2025 and 2024 and the results of its operations and its cash flows for the years in the two-year period ended October 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt about the Company’s Ability to Continue as a Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1, the Company has incurred net losses and negative cash flow from operations. These factors, and the need for additional financing in order for the Company to meet its business plans raises substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
