Report of Independent Registered Public Accounting Firm

To the Plan Participants and the Plan Administrator of UBS 401(k) Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of UBS 401(k) Plan (the Plan) as of December 31, 2025 and 2024, and the related statement of changes in net assets available for benefits for the year ended December 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 net assets available for benefits of the Plan at December 31, 2025 and 2024, and the changes in its net assets available for benefits for the year ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’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 Plan 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan 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 Plan’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.

Supplemental Schedule Required by ERISA

The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2025 (referred to as the “supplemental schedule”), has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The information in the supplemental schedule is the responsibility of the Plan’s management. Our audit procedures included determining whether the information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the information, we evaluated whether such information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the information is fairly stated, in all material respects, in relation to the financial statements as a whole.

NOTE 1 DESCRIPTION OF THE PLAN

The following description of the UBS 401(k) Plan (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the provisions of the Plan and detailed definitions of various Plan terms.

General

UBS AG (the Company) is the Plan sponsor for the Plan. The Plan, a defined-contribution plan, provides retirement benefits to eligible employees of the Company’s United States operations including eligible employees of UBS Americas Holdings LLC and subsidiaries of UBS Americas Holdings LLC. Subject to certain exceptions, all full- and part-time employees on the Company’s U.S. payroll platform are eligible to participate in the Plan upon completion of one hour of service. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended.

The Company’s Plan is administered by the Plan Administrator (Employee Benefits Committee of UBS AG). Northern Trust Company (the Trustee) is the Plan’s trustee. Alight (formerly Aon Hewitt) is the Plan’s record-keeper and Mercer serves as the Plan’s investment advisor.

For a summary of investment options in the Plan, refer to Note 3.

Plan Amendments

The Plan, as restated for January 1, 2020, and amended, as executed and adopted on December 28, 2021, October 22, 2024, and, most recently, December 4th, 2025, to reflect a change in the collection of plan expenses.

Administrative Expenses

The reasonable expenses incident to the operation of the Plan, including the compensation of the Trustee, attorneys, fiduciaries, and such other technical and clerical assistance as may be required, shall be paid from the Trust Fund in accordance with applicable law; provided, however, that the Company, in its discretion, may elect to pay all or part of such expenses. To the extent any such reasonable expenses are paid from the Trust Fund and not otherwise paid from the forfeiture suspense account or other account from which reasonable expenses may be paid (in each case, paid as determined by the Plan Administrator in its sole discretion), they shall be allocated to the Accounts of Participants pro rata. User fees attributable to investments made through the self-directed mutual fund window shall be charged and allocated to the Accounts of the Participant using that feature, including both active and former Employees.

Participant Contributions

A participant’s contributions can consist of “pre-tax contributions,” which reduce the participant’s taxable compensation and “after-tax contributions/401(k) Roth contributions,” which do not reduce a participant’s taxable compensation, and “rollovers,” which are transfers from other tax-qualified retirement plans.

Plan participants may elect to contribute to the Plan on a pre-tax, after-tax, and/or Roth basis, an amount ranging from 1% to 85% of their eligible compensation, including from 1% to 85% of their discretionary annual incentive bonus, subject to the maximum allowable contribution limit established by the Code. The maximum allowable combined pre-tax and Roth 401(k) contributions was $23,500. The maximum allowable combined pre-tax and Roth 401(k) contributions for participants who attained age 50-59, or 64+ on or before December 31, 2025 was $31,000. The maximum allowable combined pre-tax and Roth 401(k) contributions for participants who attained age 60-63, on or before December 31, 2025 was $34,750. These limits are subject to change in future years to be consistent with IRS limitations. There are also maximum allowable limits for after-tax contributions, being $23,500 for non-highly compensated participants and $18,500 for highly compensated employees.

Subject to certain limitations, the Company contributes an amount (the Company Match) up to 100% of the first 6% of each participant’s eligible annual compensation which the participant contributes to the Plan for Plan years starting in 2017. The Plan had a $3,000 annual maximum limit for 2017 and $4,500 for 2018, $5,850 for 2019 and $8,000 for 2020 and thereafter. There is a three-year cliff vesting requirement and an end of year employment requirement on the Company Match.

NOTE 1 DESCRIPTION OF THE PLAN

(continued)

Company Contributions

The Company uses

pre-tax,

Roth 401(k), and

a

f

ter-tax contributions in determining the amount of the Company’s matching contri

bu

tion for each participant. For Plan years beginning in 2017, the Company Match was calculated by multiplying each participant’s

pre-tax,

Roth 401(k) and

after-tax

contributions (up to 6% of eligible compensation) by 100% and is limited to $3,000 on an annual basis. Company Match contributions are contributed on a payroll basis based on the participants contributions and year to date annual eligible retirement earnings. For 2018, the annual Company Match was limited to $4,500, for 2019 the annual Company Match is $5,850 and for 2020 and thereafter the annual Company Match is $8,000.

Company Match contributions and earnings are invested according to the participant’s investment elections in effect for Company contributions, which can be different or similar to their

pre-tax,

Roth 401(k), and

after-tax

contribution elections.

The Company also provides a Retirement Contribution (basic profit-sharing contribution) equal to a percentage of the participant’s eligible compensation based on the participant’s years of service with the Company as of the beginning of the plan year and their eligible compensation up to the annual IRC compensation limit ($350,000 for 2025). The Plan has a three-year cliff vesting requirement and an end of year employment requirement on the Company contribution.

The Qualified Deferred Payment (QDP) feature is a supplemental profit-sharing contribution provided to participants who satisfy certain eligibility requirements. The contribution amount is based on a participant’s age at the beginning of the plan year. QDP contributions and earnings are invested according to the participant’s investment elections in effect for Company contributions, which can be different or similar to their

pre-tax,

Roth 401(k), and

after-tax

contribution elections.

If a participant has not selected his or her investment elections, the Company Contributions are invested in the

age-appropriate

Vanguard Target Date Retirement Fund, the default investment option. The determination of the Target Date Fund is based on the participant’s year of birth.

Participant Accounts

Under the Plan, each participant has two accounts—an employee account (Em

pl

oyee Account) and a company account (Com

p

any Account). The Company Account is funded; per payroll for the Company Match, annually for the Company Retirement Contribution and, per specific payrolls for the QDP. The participant can change their investment elections for Company Contributions (Company Match, Company Retirement Contribution, and QDP) as well as their own contributions

(pre-tax,

401(k) Roth and

After-tax)

at any time. In addition, they can make different investment elections for their Company Contributions,

before-tax

contributions, Roth 401(k) contributions and

after-tax

contributions.

The participant’s Employee Account reflects any contributions made by the participant (such as

before-tax

contributions, Roth 401(k) and

after-tax

contributions), in addition to income, gains, losses, withdrawals, distributions, loans, and expenses attributable to these contributions.

The participant’s Company Account reflects his/her share of the Company’s contributions from the Company match, the Company retirement contribution, and the QDP for each plan year and the income, gains, losses, withdrawals, distributions, and expenses attributable to these Company contributions.

Vesting

Participants are fully vested in their Employee Account. A participant becomes fully vested in his or her Company Account after three years of service, or, while in service as an employee and either attaining age 65, attaining age 55 with 10 years of service, becoming totally and permanently disabled, or upon death.

Forfeited Accounts

Forfeited balances of terminated participants’ unvested Company Accounts contributions are used to reduce the Company’s total contributions to the Plan. For the years ended December 31, 2025, and 2024 total forfeitures of $15,149,695 and $11,788,343 respectively were used to reduce the Company contributions. The remaining balances in the forfeiture account as of December 31, 2025, and December 31, 2024, were $1,998,904. and $2,173,590 respectively.

NOTE 1 DESCRIPTION OF THE PLAN

(continued)

Payment of Benefits

Upon the termination of employment for any reason, including death, a participant or his or her beneficiary may receive a distribution of the entire vested account balance, which is generally a

lump-sum

cash payment. However, if any portion of such participant’s account is invested in the UBS Stock Fund, then the participant may elect to receive such portion in UBS shares. If the account balance is greater than $1,000, the participant may elect to defer the lump-sum distribution until a date not to extend beyond April 1 of the year following the year that the participant attains age 70 1/2. Note, age has changed to 72 for 2020 and 73 if reaching the age of 72 after December 31, 2022.

A participant may elect to withdraw all or part of their account balance after attaining age 59 1/2, as provided by the Plan.

After-tax

contributions, including any income and loss thereon, may be withdrawn by participants at any time in accordance with the Plan’s provisions. Withdrawals of

pre-tax

contributions, Roth 401(k), or vested Company contributions are permitted, subject to certain limitations as set forth in the Code. All withdrawals or a portion thereof are subject to taxation as set forth in the Code.

Notes Receivable from Participants

Notes receivable from participants represents participant loans which are permitted under certain conditions provided for by the Plan. Participants can borrow up to the lesser of 50% of their vested account balance or $50,000. The $50,000 limit is reduced by the excess of the participant’s highest outstanding loan balance from his or her account during the 12-month period before the loan is made (even if repaid) over the participant’s outstanding loan balance on the date the loan is made.

The loan repayment shall not exceed a five-year period, except for loans related to the purchase of a primary residence. These loans shall not exceed 25 years.

The interest rates on the loans range from 5.25 to 10.50%. All loans, including interest, are to be repaid in level amounts through payroll deductions to be no less frequent than quarterly over the life of the loan.

Plan Termination

The Company has not expressed any intent to terminate the Plan, although it reserves the right to terminate the Plan at any time, subject to the provisions of ERISA. In the event the Plan is wholly or partially terminated, or upon the complete discontinuance of contributions under the Plan by any entity of the Company, each participant affected shall become fully vested in his/her Company Account. Any unallocated assets of the Plan then held by the Trustee shall be allocated among the appropriate Company Accounts and Employee Accounts of the participants and will be distributed in a manner determined by the Company.

NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

The accompanying financial statements are prepared on the accrual basis of accounting in conformity with U.S. generally accepted accounting principles (U.S. GAAP).

Payment of Benefits

Benefits to participants are recorded when paid.

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2025 or 2024. If a participant ceases to make loan repayments and the Plan administrator deems the participant loan to be a distribution, the participant loan balance is reduced, and a benefit payment is recorded.

Use of Estimates

The preparation of the accompanying financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Valuation of Investments and Income Recognition

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis and dividends are recorded on the ex-dividend date. Net appreciation/depreciation includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Investments held by the Plan are stated at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. (See Note 3 for a discussion of fair value measurement).

Table of Contents

NOTE 3 FAIR VALUE MEASUREMENT

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction (i.e., exit price).

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical financial instruments (Level 1) and the lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input to the fair value measurement in its entirety requires considerable judgment and involves considering a number of factors specific to the financial instruments.

The following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2025 and 2024.

Mutual funds: Funds that are actively traded on an exchange are priced at the net asset value (NAV) of shares held by the Plan at year end. Funds that are not actively traded on an exchange are priced at NAV using inputs that corroborate the NAV with observable (i.e., ongoing redemption and/or subscription activity) market-based data.

Common and collective trust funds: Funds that are actively traded on an exchange are priced at the NAV of shares held by the Plan at year end (e.g., bond funds, equity funds, target date funds, etc.). Funds that are not actively traded on an exchange are priced at NAV using inputs that corroborate the NAV with observable (i.e., ongoing redemption and/or subscription activity) market-based data.

Self-Directed Brokerage Accounts: Mutual funds and money market funds valued at the list price at NAV of shares held by the Plan at the valuation date.

Money market funds: Funds record their corresponding value at $1 NAV. Investments are valued at amortized cost unless this would not represent fair value.

UBS Stock Fund: Actively traded securities are valued at the closing price reported on the active market on which the individual securities are traded.

Common Stock: Actively traded securities are valued at the closing price reported on the active market on which the individual securities are traded.

Real Estate Fund: Actively traded securities are valued at the closing price reported on the active market on which the individual securities are traded.

Participatory Note: Participatory notes are issued by registered Foreign Institutional Investor (FII) to overseas investment and transferable by endorsement and delivery.

Short-term investments: Funds that are actively traded on an exchange are priced at the net asset value (NAV) of shares held by the Plan at year end. Funds that are not actively traded on an exchange are priced at NAV using inputs that corroborate the NAV with observable (i.e., ongoing redemption and/or subscription activity) market-based data.

The methods described above may produce a fair value calculation that may not indicate net realizable value or reflect future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

There were no transfers between levels in 2025 and 2024.

NOTE 3 FAIR VALUE MEASUREMENT

(continued)

At December 31, 2025, the investments held by the Plan within the fair value hierarchy are as follows:

In the prior year’s financial statements, one of the equity funds was classified as a bond fund. Upon further analysis, it was determined that an equity fund classification was more appropriate. In 2025, the Plan revised its fair value hierarchy classification from bond fund to equity fund, and the 2024 presentation has been adjusted accordingly for this immaterial amount.

At December 31, 2024, the investments held by the Plan within the fair value hierarchy are as follows:

(continued)

The above provides a general description of the investments. Participants should refer to the Investment Options Guide for information on the investment objectives and strategy of each investment opt

io

n.

NOTE 4 RISKS AND UNCERTAINTIES

The Plan invests in several investment instruments that are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is quite possible for the value of investment securities to change in the near term. The changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

NOTE 5 RELATED-PARTY TRANSACTIONS

For the year ended December 31, 2025, the Plan makes certain investments through the Trust, which are considered to be party-in-interest transactions for which a statutory exemption from the prohibited transaction regulation exists. They are as follows:

Certain officers and employees of the Plan’s sponsor (who may also be participants in the Plan) perform administrative services related to the Plan’s operation, record keeping and financial reporting. The Plan’s sponsor pays these individuals’ salaries and also pays certain other administrative expenses on the Plan’s behalf. The foregoing transactions are not deemed prohibited party-in-interest transactions because they are covered by statutory and administrative exemptions from the Code and ERISA’s rules on prohibited transactions.

NOTE 6 TAX STATUS

The Plan is a result of the merger and renaming of the SIP Plan and the Plus Plan, effective January 1, 2015. Both the SIP Plan and the Plus Plan have favorable determination letters issued by the IRS, dated July 29, 2014, and September 9, 2014, respectively, stating that the SIP Plan and the Plus Plan are qualified under Section 401(a) of the Code and, therefore, the related trust is exempt from taxation. The Plan has been amended and restated since the receipt of the SIP and Plus Plan determination letters. The plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes the Plan, as amended and restated, is qualified and the related trust is tax-exempt.

U.S. GAAP requires Plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more-likely-than-not, based on the technical merits, to be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2025, there are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions.

NOTE 7 RECONCILIATION OF FINANCIAL STATEMENTS TO FORM 5500

The following is a reconciliation of net assets available for benefits per the financial statements to the Form 5500 as of:

The accompanying financial statements present benefits distributions to participants on cash basis. The Form 5500 requires benefits distributions to be reported as a benefits payable in the plan year. Therefore, the adjustment from cash basis to accrual basis for benefits distributions represents a reconciling item.

The following is a reconciliation of net increase in net assets per the financial statements to the Form 5500 for the year ended December 31, 2025:

NOTE 8 SUBSEQUENT EVENTS

The Plan has evaluated the impact of subsequent events through June 29, 2026, the date the financial statements financial statements were available to be issued. No subsequent events have been recognized or required additional disclosure in the financial statements.
