ANNUAL SHAREHOLDER REPORT | July 31, 2026

This annual shareholder report contains important information about the First Trust Core Investment Grade ETF (the “Fund”) for the year of August 1, 2025 to July 31, 2026 (the “Period”). You can find additional information about the Fund at www.ftportfolios.com/fund-documents/etf/FTCB. You can also request this information by contacting us at 1-800-621-1675 or [email protected].

WHAT WERE THE FUND COSTS FOR THE LAST YEAR?

(Based on a hypothetical $10,000 investment)

Fund	Costs of a $10,000 investment	Costs paid as a percentage of a $10,000 investment
First Trust Core Investment Grade ETF	$56⁽¹⁾	0.55%⁽¹⁾

⁽¹⁾	Excludes any Acquired Fund Fees and Expenses of the underlying investment companies in which the Fund invests.

HOW DID THE FUND PERFORM LAST YEAR? WHAT AFFECTED THE FUND’S PERFORMANCE?

The Fund returned 3.26% for the 12 months ended July 31, 2026. The Fund outperformed its benchmark, the Bloomberg US Aggregate Bond Index, which returned 2.71% for the same Period.

This 55 basis points (“bps”) of outperformance was due to several factors during the Period:

Overall, the Fund generated a greater level of income than its benchmark, which was beneficial to relative performance.
The Fund benefited from its overweight allocations to agency mortgage-backed securities (“MBS”) and securitized credit as spreads tightened over the Period.
The Fund benefited from security selection within the corporate sector, particularly in the Industrial and Financial subsectors.
Derivatives are typically used to manage interest rate risk as well as offer the potential for income enhancing strategies. Overall, the usage of derivatives was mildly detrimental to Fund’s relative return, as the Fund generally maintained a longer duration compared to the benchmark, which hurt performance as yields moved higher across the curve.

FUND PERFORMANCE (November 7, 2023 to July 31, 2026)

The performance line graph below shows the performance of a hypothetical $10,000 initial investment in the Fund over a ten-year period (or for the life of the Fund, if shorter). The subsequent account value as of the end of the Period is listed next to the name of the Fund or index, as applicable. The performance table below shows the average annual total returns of the Fund for the past one-, five-, and ten-year periods, as applicable (or for the life of the Fund, if shorter), as of the end of the Period. Both the line graph and performance table compare the Fund’s performance to an appropriate broad-based index and may compare to additional indices reflecting the market segment(s) in which the Fund invests over the same periods.

Performance in securitized product investment strategies can be impacted from the benefits of purchasing odd lot positions. The impact of these investments can be particularly meaningful when funds have limited assets under management and may not be a sustainable source of performance as a fund grows in size.

⁽²⁾ The ratings are by one or more nationally recognized statistical rating organizations (NRSROs), including S&P Global Ratings, Moody’s Investors Service, Inc., Fitch Ratings, DBRS, Inc., Kroll Bond Rating Agency, Inc. or a comparably rated NRSRO. For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used. A credit rating is an assessment provided by a NRSRO of the creditworthiness of an issuer with respect to debt obligations. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. “NR” indicates no rating. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Agency, U.S. Agency mortgage-backed, and U.S. Treasury securities appear under “Government & Agency.” Credit ratings are subject to change.

WHAT WERE THE FUND COSTS FOR THE LAST YEAR?

(Based on a hypothetical $10,000 investment)

Fund	Costs of a $10,000 investment	Costs paid as a percentage of a $10,000 investment
First Trust AAA CMBS ETF	$36⁽¹⁾	0.35%⁽¹⁾

⁽¹⁾	Excludes any Acquired Fund Fees and Expenses of the underlying investment companies in which the Fund invests.

HOW DID THE FUND PERFORM LAST YEAR? WHAT AFFECTED THE FUND’S PERFORMANCE?

The Fund returned 3.98% for the 12 months ended July 31, 2026. The Fund outperformed its benchmark, the Bloomberg Non-Agency Investment Grade CMBS: US Aggregate Eligible Aaa Index, which returned 3.90% for the same Period.

This 8 basis points (“bps”) of outperformance was due to several factors during the Period:

Overall, the Fund generated a greater level of income than its benchmark, which aided performance.
The Fund was overweight to single-asset single-borrower floating-rate securities, which was beneficial to the Fund’s performance.
The Fund added exposure to out-of-benchmark agency commercial mortgage-backed securities (“CMBS”) interest-only positions, which helped drive outperformance.
While utilized primarily to manage yield curve and duration risk, the use of derivatives was mildly detrimental to the Fund’s relative return, as the Fund generally maintained a longer duration than the benchmark, which hurt performance as yields moved higher across the curve.

The Fund’s past performance is not a good predictor of the Fund’s future performance.

Performance and Risk Disclosure

There is no assurance that any series of First Trust Exchange-Traded Fund IV (the “Trust”) described in this report (each such series is referred to as a “Fund” and collectively, as the “Funds”) will achieve its investment objective. Each Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund’s shares may therefore be less than what you paid for them. Accordingly, you can lose money by investing in a Fund.

Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost.

First Trust Advisors L.P., the Funds’ advisor, may also periodically provide additional information on Fund performance on each Fund’s webpage at www.ftportfolios.com.

How to Read This Report

This report contains information that may help you evaluate your investment. It includes details about each Fund and presents data that provides insight into each Fund’s performance and investment approach.

The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information, and other Fund regulatory filings.

First Trust Exchange-Traded Fund IV

July 31, 2026

1. Organization

First Trust Exchange-Traded Fund IV (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on September 15, 2010, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”).

This report covers the three funds (each a “Fund” and collectively, the “Funds”) listed below, each a non-diversified series of the Trust. The shares of each Fund are listed and traded on the NYSE Arca, Inc.

First Trust Core Investment Grade ETF (ticker “FTCB”)

First Trust AAA CMBS ETF (ticker “CAAA”)

First Trust Structured Credit Income Opportunities ETF (ticker “SCIO”)

Each Fund represents a separate series of shares of beneficial interest in the Trust. Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large blocks of shares known as “Creation Units.”

Each Fund is an actively managed exchange-traded fund (“ETF”). FTCB and CAAA’s investment objective seeks to maximize long-term total return. SCIO’s investment objective seeks to maximize long-term income.

Under normal market conditions, FTCB seeks to invest 100% of its Investment Portfolio in investment grade securities. Investment grade securities are those securities that are, at the time of purchase, rated as investment grade (i.e., rated Baa3/BBB- or above) by at least one nationally recognized statistical rating organization (“NRSRO”) rating such securities, or if unrated, debt securities determined by the Fund’s investment advisor to be of comparable quality. The Fund’s Investment Portfolio includes only investment grade securities purchased by the Fund’s portfolio managers (the “Investment Portfolio”) and does not include uninvested cash or any other Fund asset unconnected to the Fund’s intended portfolio, including, but not limited to, accounts receivable or assets received as part of an issuer workout.

Under normal market conditions, CAAA will invest at least 80% of its net assets (plus any borrowings for investment purposes) in commercial mortgage-backed securities with a ‘AAA’ rating (or equivalent) at the time of purchase, as determined by at least one NRSRO or, if unrated, as determined by the Fund’s investment advisor to be of comparable credit quality at the time of purchase.

Under normal market conditions, SCIO will invest at least 80% of its net assets (plus any borrowings for investment purposes) in structured credit investments.

There can be no assurance that a Fund will achieve its investment objective. The Funds may not be appropriate for all investors.

2. Significant Accounting Policies

The Funds are each considered an investment company and follow accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

A. Portfolio Valuation

Each Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Domestic debt securities are priced using data reflecting the earlier closing of the principal markets for those securities. Each Fund’s NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.

Each Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the

Page 63

Notes to Financial Statements (Continued)

First Trust Exchange-Traded Fund IV

July 31, 2026

Pricing Committee of the Funds’ investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. Each Fund’s investments are valued as follows:

Corporate bonds, corporate notes, U.S. government securities, mortgage-backed securities, asset-backed securities, municipal securities, and other debt securities are fair valued on the basis of valuations provided by a third-party pricing service approved by the Advisor’s Pricing Committee, which may use the following valuation inputs when available:

benchmark yields;

reported trades;

broker/dealer quotes;

issuer spreads;

benchmark securities;

bids and offers; and

reference data including market research publications.

Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots.

ETFs and other equity securities listed on any national or foreign exchange (excluding Nasdaq, Inc. (“Nasdaq”) and the London Stock Exchange Alternative Investment Market (“AIM”)) are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the primary exchange for such securities.

Shares of open-end funds are valued based on NAV per share.

Exchange-traded futures contracts are valued at the end of the day settlement price.

Exchange-traded options contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded options contracts are valued at the mean of their most recent bid and ask price, if both are available. Options contracts traded in the over-the-counter market may be valued as follows, depending on the market in which the investment trades: (1) the mean of the most recent bid and ask price, if available; or (2) a price based on the equivalent exchange-traded option.

Fixed income and other debt securities having a remaining maturity of sixty days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following:

the credit conditions in the relevant market and changes thereto;

the liquidity conditions in the relevant market and changes thereto;

the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);

issuer-specific conditions (such as significant credit deterioration); and

any other market-based data the Advisor’s Pricing Committee considers relevant. In this regard, the Advisor’s Pricing Committee may use last-obtained market-based data to assist it when valuing portfolio securities using amortized cost.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor’s Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV or make it difficult or

Page 64

impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:

the most recent price provided by a pricing service;

available market prices for the fixed-income security;

the fundamental business data relating to the borrower/issuer;

an evaluation of the forces which influence the market in which these securities are purchased and sold;

the type, size and cost of a security;

the financial statements of the borrower/issuer or the financial condition of the country of issue;

the credit quality and cash flow of the borrower/issuer, or country of issue, based on the Pricing Committee’s, sub-advisor’s or portfolio manager’s analysis, as applicable, or external analysis;

the information as to any transactions in or offers for the security;

the price and extent of public trading in similar securities of the borrower/issuer, or comparable companies;

10)

the coupon payments;

11)

the quality, value and salability of collateral, if any, securing the security;

12)

the business prospects of the borrower/issuer, including any ability to obtain money or resources from a parent or affiliate and an assessment of the borrower’s/issuer’s management (for corporate debt only);

13)

the prospects for the borrower’s/issuer’s industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry (for corporate debt only); and

14)

other relevant factors.

The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

o Quoted prices for similar investments in active markets.

o Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.

o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).

o Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund’s investments as of July 31, 2026, is included with each Fund’s Portfolio of Investments.

B. Securities Transactions and Investment Income

Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.

The Funds invest in interest-only securities. For these securities, if there is a change in the estimated cash flows, based on an evaluation of current information, then the estimated yield is adjusted. Additionally, if the evaluation of current information indicates a permanent impairment of the security, the cost basis of the security is written down and a loss is recognized. Debt obligations may be placed on non-accrual status and the related interest income may be reduced by ceasing current accruals and writing off interest

Page 65

Notes to Financial Statements (Continued)

First Trust Exchange-Traded Fund IV

July 31, 2026

receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.

Securities purchased or sold on a when-issued, delayed-delivery or forward purchase commitment basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. Each Fund maintains liquid assets with a current value at least equal to the amount of its when-issued, delayed-delivery or forward purchase commitments until payment is made. At July 31, 2026, the Funds had no when-issued or delayed-delivery securities. At July 31, 2026, FTCB held $112,738,543 of forward purchase commitments and $10,328,575 of forward purchase commitments sold short. At July 31, 2026, SCIO held $15,602,697 of forward purchase commitments and $3,146,115 of forward purchase commitments sold short.

C. Short Sales

Short sales are utilized to manage interest rate and spread risk, and are transactions in which securities or other instruments (such as options, forwards, futures or other derivative contracts) are sold that are not currently owned in a Fund’s portfolio. When a Fund engages in a short sale, a Fund must borrow the security sold short and deliver the security to the counterparty. Short selling allows a Fund to profit from a decline in a market price to the extent such decline exceeds the transaction costs and the costs of borrowing the securities. A Fund is charged a fee or premium to borrow the securities sold short and is obligated to repay the lenders of the securities. Any dividends or interest that accrues on the securities during the period of the loan are due to the lenders. A gain, limited to the price at which the security was sold short, or a loss, unlimited in size, will be recognized upon the termination of the short sale; which is effected by a Fund purchasing the security sold short and delivering the security to the lender. Any such gain or loss may be offset, completely or in part, by the change in the value of the long portion of a Fund’s portfolio. A Fund is subject to the risk it may be unable to reacquire a security to terminate a short position except at a price substantially in excess of the last quoted price. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to a Fund.

D. Futures Contracts

Each Fund may purchase or sell (i.e., is long or short) exchange-listed futures contracts to hedge against or gain exposure to changes in interest rates (interest rate risk). Futures contracts are agreements between a Fund and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If a Fund is not able to enter into an offsetting transaction, a Fund will continue to be required to maintain margin deposits on the futures contract. When the contract is closed or expires, a Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed or expired. This gain or loss is included in “Net realized gain (loss) on futures contracts” on the Statements of Operations.

Upon entering into a futures contract, a Fund must deposit funds, called margin, with its custodian in the name of the clearing broker equal to a specified percentage of the current value of the contract. Open futures contracts are marked-to-market daily with the change in value recognized as a component of “Net change in unrealized appreciation (depreciation) on futures contracts” on the Statements of Operations. Pursuant to the contracts, a Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are included in “Variation margin” payable or receivable on the Statements of Assets and Liabilities.

If market conditions change unexpectedly, a Fund may not achieve the anticipated benefits of the futures contract and may realize a loss. The use of futures contracts involves the risk of imperfect correlation in movements in the price of the futures contracts, interest rates and the underlying instruments.

E. Options Contracts

Each Fund may invest in exchange-listed options on U.S. Treasury securities, exchange-listed options on U.S. Treasury futures contracts, exchange-listed U.S. Treasury futures contracts and exchange-listed options on secured overnight financing rate futures contracts. FTCB and SCIO use derivative instruments primarily to hedge interest rate risk and actively manage interest rate exposure. The primary risk exposure is interest rate risk.

Each Fund may purchase (buy) or write (sell) put and call options on futures contracts and enter into closing transactions with respect to such options to terminate an existing position. A futures option gives the holder the right, in return for the premium paid, to assume

Page 66

Notes to Financial Statements (Continued)

First Trust Exchange-Traded Fund IV

July 31, 2026

a long position (call) or short position (put) in a futures contract at a specified exercise price prior to the expiration of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. Prior to exercise or expiration, a futures option contract may be closed out by an offsetting purchase or sale of a futures option of the same series. When a Fund purchases an option, the premium paid represents the cost of the option, which is included in “Options contracts purchased, at value” on the Statements of Assets and Liabilities. When a Fund writes (sells) an option, an amount equal to the premium received by a Fund is included in “Options contracts written, at value” on the Statements of Assets and Liabilities. Options are marked-to-market daily and their value is affected by changes in the value of the underlying security, changes in interest rates, changes in the actual or perceived volatility of the securities markets and the underlying securities, and the remaining time to the option’s expiration. The value of options may also be adversely affected if the market for the options becomes less liquid or the trading volume diminishes.

FTCB and SCIO use options on futures contracts in connection with hedging strategies. Generally, these strategies are applied under the same market and market sector conditions in which a Fund uses put and call options on securities. The purchase of put options on futures contracts is analogous to the purchase of puts on securities so as to hedge a Fund’s securities holdings against the risk of declining market prices. The writing of a call option or the purchasing of a put option on a futures contract constitutes a partial hedge against declining prices of securities which are deliverable upon exercise of the futures contract. If the price at expiration of a written call option is below the exercise price, a Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in a Fund’s holdings of securities. If the price when the option is exercised is above the exercise price, however, a Fund will incur a loss, which may be offset, in whole or in part, by the increase in the value of the securities held by a Fund that were being hedged. Writing a put option or purchasing a call option on a futures contract serves as a partial hedge against an increase in the value of the securities a Fund intends to acquire. Realized gains and losses on written options are included in “Net realized gain (loss) on written options contracts” on the Statements of Operations. Realized gains and losses on purchased options are included in “Net realized gain (loss) on purchased options contracts” on the Statements of Operations.

A Fund is required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Such margin deposits will vary depending on the nature of the underlying futures contract (and the related initial margin requirements), the current market value of the option and other futures positions held by a Fund. A Fund will pledge in a segregated account at a Fund’s custodian, liquid assets, such as cash, U.S. government securities or other high-grade liquid debt obligations equal in value to the amount due on the underlying obligation. Such segregated assets will be marked-to-market daily, and additional assets will be pledged in the segregated account whenever the total value of the pledged assets falls below the amount due on the underlying obligation.

The risks associated with the use of options on future contracts include the risk that a Fund may close out its position as a writer of an option only if a liquid secondary market exists for such options, which cannot be assured. A Fund’s successful use of options on futures contracts depends on the Advisor’s ability to correctly predict the movement in prices on futures contracts and the underlying instruments, which may prove to be incorrect. In addition, there may be imperfect correlation between the instruments being hedged and the futures contract subject to option.

F. Interest-Only Securities

An interest-only security (“IO Security”) is the interest-only portion of a mortgage-backed security that receives some or all of the interest portion of the underlying mortgage-backed security and little or no principal. A reference principal value called a notional value is used to calculate the amount of interest due to the IO Security. IO Securities are sold at a deep discount to their notional principal amount. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of an IO Security will fall. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of an IO Security will rise. These securities, if any, are identified on each Fund’s Portfolio of Investments.

G. Principal-Only Securities

A principal-only security (“PO Security”) is the principal-only portion of a mortgage-backed security that does not receive any interest, is priced at a deep discount to its redemption value and ultimately receives the redemption value. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of a PO Security will rise. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of a PO Security will fall. These securities, if any, are identified on the Portfolio of Investments.

Page 67

First Trust Exchange-Traded Fund IV

July 31, 2026

H. Stripped Mortgage-Backed Securities

Stripped mortgage-backed securities are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each with a specified percentage of the underlying security’s principal or interest payments. Mortgage-backed securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security known as an IO Security and all of the principal is distributed to holders of another type of security known as a PO Security. These securities, if any, are identified on the Portfolio of Investments.

I. Mortgage Dollar Rolls and TBA Transactions

Each Fund may invest, without limitation, in mortgage dollar rolls. The Funds intend to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Funds’ investment advisor. In a mortgage dollar roll, a Fund will sell (or buy) mortgage-backed securities for delivery on a specified date and simultaneously contract to repurchase (or sell) substantially similar (same type, coupon and maturity) securities on a future date. Mortgage dollar rolls are recorded as separate purchases and sales in a Fund. Each Fund may also invest in TBA Transactions. A TBA Transaction is a method of trading mortgage-backed securities. TBA Transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA Transaction, the buyer and the seller agree on general trade parameters such as agency, settlement date, par amount and price.

J. Affiliated Transactions

FTCB invests in securities of affiliated funds. FTCB investment performance and risks are directly related to the investment performance and risks of the affiliated funds. The affiliated funds’ financial statements may be found at SEC.gov. Dividend income, if any, realized gains and losses, and change in appreciation (depreciation) from affiliated funds are presented on the Statements of Operations.

Amounts relating to investments in affiliated funds at July 31, 2026, and for the fiscal year then ended are as follows:

K. Dividends and Distributions to Shareholders

Dividends from net investment income of each Fund, if any, are declared and paid monthly, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by each Fund, if any, are distributed at least annually. Each Fund may also designate a portion of the amount paid to redeeming shareholders as a distribution for tax purposes.

Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom the shares were purchased makes such option available. Such shares will generally be reinvested by the broker based upon the market price of those shares and investors may be subject to customary brokerage commissions charged by the broker.

Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Funds and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.

L. Income Taxes

Each Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, each Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of each Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.

The Funds are subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable period ended 2024, and taxable years ended 2025 and 2026 remain open to federal and state audit. As of July 31, 2026, management has evaluated the application of these standards to the Funds and has determined that no provision for income tax is required in the Funds’ financial statements for uncertain tax positions.

Each Fund intends to utilize provisions of the federal income tax laws, which allow it to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. Each Fund is subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At July 31, 2026, for federal income tax purposes, each applicable Fund had a capital loss carryforward available that is shown in the following table, to the extent provided by regulations, to offset future capital gains. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to each applicable Fund’s shareholders.

In order to present paid-in capital and accumulated distributable earnings (loss) (which consists of accumulated net investment income (loss), accumulated net realized gain (loss) on investments and net unrealized appreciation (depreciation) on investments) on the Statements of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to paid-in capital, accumulated net investment income (loss) and accumulated net realized gain (loss) on investments. These adjustments are primarily due to the difference between book and tax treatments of income and gains on various investment securities held by the Funds. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended July 31, 2026, the adjustments for each Fund were as follows:

	Accumulated Net Investment Income (Loss)	Accumulated Net Realized Gain (Loss) on Investments	Paid-In Capital
First Trust Core Investment Grade ETF	$(23,903 )	$23,903	$—
First Trust AAA CMBS ETF	5,494	(5,494 )	—
First Trust Structured Credit Income Opportunities ETF	(15,609 )	15,609	—

As of July 31, 2026, the aggregate cost, gross unrealized appreciation, gross unrealized depreciation, and net unrealized appreciation/(depreciation) on investments (including short positions and derivatives, if any) for federal income tax purposes were as follows:

	Tax Cost	Gross Unrealized Appreciation	Gross Unrealized (Depreciation)	Net Unrealized Appreciation (Depreciation)
First Trust Core Investment Grade ETF	$2,692,971,416	$5,119,827	$(50,011,711 )	$(44,891,884 )

M. Expenses

Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (see Note 3).

N. Segment Reporting

An operating segment is defined in FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The CODM is the President and Chief Executive Officer of each Fund. Each Fund operates as a single operating segment. Each Fund’s income, expenses, assets, changes in net assets resulting from operations and performance are regularly monitored and assessed as a whole by the CODM responsible for oversight functions of each Fund, using the information presented in the financial statements and financial highlights.

3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements

First Trust, the investment advisor to the Funds, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the selection and ongoing monitoring of the securities in each Fund’s portfolio, managing the Funds’ business affairs and providing certain administrative services necessary for the management of the Funds.

Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust manages the investment of each Fund’s assets and is responsible for the expenses of each Fund, including the cost of transfer agency, custody, fund administration, legal, audit, and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, acquired fund fees and expenses, and extraordinary expenses, which are paid by each respective Fund. The annual unitary management fee payable by FTCB to First Trust for these services will be reduced at certain levels of FTCB’s net assets (“breakpoints”) and calculated pursuant to the following schedule:

Breakpoints	FTCB
Fund net assets up to and including $2.5 billion	0.55000 %
Fund net assets greater than $2.5 billion up to and including $5 billion	0.53625 %
Fund net assets greater than $5 billion up to and including $7.5 billion	0.52250 %
Fund net assets greater than $7.5 billion up to and including $10 billion	0.50875 %
Fund net assets greater than $10 billion	0.49500 %

Effective February 1, 2026, CAAA and SCIO have agreed to pay First Trust an annual unitary management fee based on each Fund’s average daily net assets at a rate set forth below:

Rate

From January 1, 2026 to January 31, 2026, for each of CAAA and SCIO, the Advisor waived management fees of 0.16% of average daily net assets. During any period in which such waiver was in effect, each such Fund was not eligible for any breakpoint discounts. During the year ended July 31, 2026, the Advisor waived fees of $3,894 and $19,289 for CAAA and SCIO, respectively.

The Trust has multiple service agreements with The Bank of New York Mellon (“BNY”). Under the service agreements, BNY performs custodial, fund accounting, certain administrative services, and transfer agency services for each Fund. As custodian, BNY is responsible for custody of each Fund’s assets. As fund accountant and administrator, BNY is responsible for maintaining the books and records of each Fund’s securities and cash. As transfer agent, BNY is responsible for maintaining shareholder records for each Fund. BNY is a subsidiary of The Bank of New York Mellon Corporation, a financial holding company.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a target outcome fund or an index fund.

Additionally, the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation, Risk and Regulatory Oversight Committee, the Vice Chair of the Audit Committee, the Lead Independent Trustee and the Vice Lead Independent Trustee

are paid annual fees to serve in such capacities, with such compensation, prior to January 1, 2026, allocated pro rata among each fund in the First Trust Fund Complex based on net assets, and effective January 1, 2026, allocated equally among each fund in the First Trust Fund Complex. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.

4. Purchases and Sales of Securities

For the fiscal year ended July 31, 2026, the cost of purchases and proceeds from sales and paydowns of U.S. Government securities and non-U.S. Government securities for each Fund, excluding short-term investments, investments sold short and in-kind transactions, were as follows:

5. Borrowings

The Trust, on behalf of SCIO, along with First Trust Exchange-Traded Fund III, First Trust Series Fund and First Trust Variable Insurance Trust, has a credit agreement with BNY (the “Credit Agreement”) as administrative agent for a group of lenders. The borrowing rate is the higher of the federal funds effective rate and the adjusted daily simple SOFR rate plus 1.00%. The commitment amount under the Credit Agreement is $620 million and such commitment amount may be increased up to $700 million with the consent of one or more lenders. BNY charges on behalf of the lenders a commitment fee of 0.15% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans and an agency fee. The commitment fee and agency fee are allocated amongst the funds that have access to the credit line pursuant to procedures approved by the Board of Trustees. To the extent that SCIO accesses the credit line, there would also be an interest fee charged. SCIO did not draw on the credit line during the fiscal year ended July 31, 2026.

7. Creations, Redemptions and Transaction Fees

Each Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as “Authorized Participants” have contractual arrangements with a Fund or one of the Fund’s service providers to purchase and redeem Fund shares directly with the Fund in Creation Units. Prior to the start of trading on every business day, a Fund publishes through the National Securities Clearing Corporation the “basket” of securities, cash or other assets that it will accept in exchange for a Creation Unit of the Fund’s shares. An Authorized Participant that wishes to effectuate a creation of a Fund’s shares deposits with the Fund the “basket” of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the Fund’s shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a Creation Unit of a Fund’s shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in a Fund’s shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of a Fund’s shares at or close to the NAV per share of the Fund.

Each Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket.

Each Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by a Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.

8. Distribution Plan

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are authorized to pay an amount up to 0.25% of their average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2027.

9. Indemnification

The Trust, on behalf of the Funds, has a variety of indemnification obligations under contracts with its service providers. The Trust’s maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

10. Subsequent Events

Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements that have not already been disclosed.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements and financial highlights 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 Funds 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 and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their 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 Funds’ 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 and financial highlights, 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 and financial highlights. 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 and financial highlights. Our procedures included confirmation of securities owned as of July 31, 2026, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Statement Regarding the Basis for the Board’s Approval of Investment Advisory Contract (Item 11 of Form N-CSR)

The Board of Trustees of First Trust Exchange-Traded Fund VIII (the “Trust”), including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement (the “Agreement”) with First Trust Advisors L.P. (the “Advisor”) on behalf of each of the following series of the Trust (each a “Fund” and collectively, the “Funds”):

First Trust AAA CMBS ETF (CAAA)
First Trust Core Investment Grade ETF (FTCB)
First Trust Structured Credit Income Opportunities ETF (SCIO)

Other Information (Continued)

First Trust Exchange-Traded Fund IV

July 31, 2026 (Unaudited)

The Board approved the continuation of the Agreement for each Fund for a one-year period ending June 30, 2027 at a meeting held on June 7–8, 2026. The Board determined for each Fund that the continuation of the Agreement is in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.

To reach this determination for each Fund, the Board considered its duties under the Investment Company Act of 1940, as amended (the “1940 Act”), as well as under the general principles of state law, in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; the fiduciary duty of investment advisors with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards have fulfilled their duties; and the factors to be considered by the Board in voting on such agreements. At meetings held on April 13, 2026 and June 7–8, 2026, the Board, including the Independent Trustees, reviewed materials provided by the Advisor responding to requests for information from counsel to the Independent Trustees, submitted on behalf of the Independent Trustees, that, among other things, outlined: the services provided by the Advisor to each Fund (including the relevant personnel responsible for these services and their experience); the unitary fee rate schedule payable by each Fund as compared to fees charged to a peer group of funds (the “Expense Group”) and a broad peer universe of funds (the “Expense Universe”), each assembled by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent source, and as compared to fees charged to other clients of the Advisor, including other exchange-traded funds (“ETFs”) managed by the Advisor; the expense ratio of each Fund as compared to expense ratios of the funds in the Fund’s Expense Group and Expense Universe; performance information for each Fund, including comparisons of each Fund’s performance to that of one or more relevant benchmark indexes and to that of a performance group of funds and a broad performance universe of funds (the “Performance Universe”), each assembled by Broadridge; the nature of expenses incurred in providing services to each Fund and the potential for the Advisor to realize economies of scale, if any; profitability and other financial data for the Advisor; any indirect benefits to the Advisor and its affiliate, First Trust Portfolios L.P. (“FTP”); and information on the Advisor’s compliance program. The Board reviewed initial materials with the Advisor at the meeting held on April 13, 2026, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor. Following the April meeting, counsel to the Independent Trustees, on behalf of the Independent Trustees, requested certain clarifications and supplements to the materials provided, and the information provided in response to those requests was considered at an executive session of the Independent Trustees and their counsel held prior to the June 7–8, 2026 meeting, as well as at the June meeting. The Board applied its business judgment to determine whether the arrangement between the Trust and the Advisor continues to be a reasonable business arrangement from each Fund’s perspective. The Board determined that, given the totality of the information provided with respect to the Agreement, the Board had received sufficient information to renew the Agreement. The Board considered that shareholders chose to invest or remain invested in a Fund knowing that the Advisor manages the Fund and knowing the Fund’s unitary fee.

In reviewing the Agreement for each Fund, the Board considered the nature, extent and quality of the services provided by the Advisor under the Agreement. The Board considered that the Advisor is responsible for the overall management and administration of the Trust and each Fund and reviewed all of the services provided by the Advisor to the Funds, as well as the background and experience of the persons responsible for such services. The Board noted that each Fund is an actively-managed ETF. The Board noted that the Advisor’s Government & Securitized Products Team is responsible for the day-to-day management of CAAA’s and SCIO’s investments, and that the Advisor’s Government & Securitized Products Team and Investment Grade Fixed Income Team are responsible for day-to-day management of FTCB’s investments. The Board considered the background and experience of the members of the Teams and noted the Board’s prior meetings with members of the Teams. The Board considered the Advisor’s statement that it applies the same oversight model internally with its Government & Securitized Products Team and Investment Grade Fixed Income Team as it uses for overseeing external sub-advisors, including portfolio risk monitoring and performance review. In reviewing the services provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor’s and each Fund’s compliance with the 1940 Act, as well as each Fund’s compliance with its investment objective, policies and restrictions. The Board also considered a report from the Advisor with respect to its risk management functions related to the operation of the Funds. Finally, as part of the Board’s consideration of the Advisor’s services, the Advisor, in its written materials and at the April 13, 2026 meeting, described to the Board the scope of its ongoing investment in additional personnel and infrastructure to maintain and improve the quality of services provided to the Funds and the other funds in the First Trust Fund Complex. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of the services provided to the Trust and each Fund by the Advisor under the Agreement have been and are expected to remain satisfactory and that the Advisor has managed each Fund consistent with its investment objective, policies and restrictions.

The Board considered the unitary fee rate schedule payable by each Fund under the Agreement for the services provided. The Board considered that as part of the unitary fee the Advisor is responsible for each Fund’s expenses, including the cost of transfer agency,

custody, fund administration, legal, audit and other services and license fees, if any, but excluding the fee payment under the Agreement and interest, taxes, acquired fund fees and expenses, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses, if any. The Board received and reviewed information showing the fee rates and expense ratios of the peer funds in the Expense Groups, as well as advisory and unitary fee rates charged by the Advisor to other fund (including ETFs) and non-fund clients, as applicable. Because each Fund pays a unitary fee, the Board determined that expense ratios were the most relevant comparative data point. The Board noted that, effective February 1, 2026, CAAA’s and SCIO’s unitary fee rate was reduced to an annual rate of 0.29% and 0.69% of its average daily net assets, respectively. Based on the information provided, the Board noted that the total (net) expense ratio for FTCB and SCIO was above the median total (net) expense ratio of the peer funds in its respective Expense Group and that the total (net) expense ratio for CAAA was below the median total (net) expense ratio of the peer funds in its Expense Group. With respect to the Expense Groups, the Board discussed with the Advisor limitations in creating peer groups for actively-managed ETFs, and different business models that may affect the pricing of services among ETF sponsors. The Board took these limitations and differences into account in considering the peer data. With respect to fees charged to other non-ETF clients, the Board considered differences between the Funds and other non-ETF clients that limited their comparability. In considering the unitary fee rate schedules overall, the Board also considered the Advisor’s statement that it seeks to meet investor needs through innovative and value-added investment solutions and the Advisor’s demonstrated long-term commitment to each Fund and the other funds in the First Trust Fund Complex.

The Board considered performance information for each Fund. The Board noted the process it has established for monitoring each Fund’s performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor for the Funds. The Board determined that this process continues to be effective for reviewing each Fund’s performance. The Board also received and reviewed information comparing each Fund’s performance for the one-year period ended December 31, 2025 to the performance of the funds in its Performance Universe and to that of a benchmark index.

On the basis of all the information provided on the unitary fee and performance of each Fund and the ongoing oversight by the Board, the Board concluded that the unitary fee for each Fund continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor to each Fund under the Agreement.

The Board considered information and discussed with the Advisor whether there were any economies of scale in connection with providing advisory services to the Funds at current asset levels and whether the Funds may benefit from any economies of scale. The Board noted that the unitary fee rate schedule for FTCB includes breakpoints pursuant to which the unitary fee rate will be reduced as assets of the Fund meet certain thresholds. The Board considered the Advisor’s statement that it believes that its expenses relating to providing advisory services to the Funds will increase during the next twelve months as the Advisor continues to build infrastructure, including technology, and add new staff. The Board also noted that under the unitary fee structure, any reduction in expenses associated with the management and operations of the Funds would benefit the Advisor, but that the unitary fee structure provides a level of certainty in expenses for shareholders of the Funds. The Board concluded that the unitary fee rate schedule for each Fund reflects an appropriate level of sharing of any economies of scale that may be realized in the management of the Fund at current asset levels. The Board considered the revenues and allocated costs (including the allocation methodology) of the Advisor in serving as investment advisor to each Fund for the twelve months ended December 31, 2025 and the estimated profitability level for each Fund calculated by the Advisor based on such data, as well as complex-wide and product-line profitability data, for the same period. The Board noted the inherent limitations in the profitability analysis and concluded that, based on the information provided, the Advisor’s profitability level for each Fund was not unreasonable. In addition, the Board considered indirect benefits described by the Advisor that may be realized from its relationship with the Funds. The Board considered that the Advisor had identified as an indirect benefit to the Advisor and FTP the exposure of their products to investors and brokers who, absent their exposure to the Funds, may have had no dealings with the Advisor or FTP, and noted that the Advisor does not utilize soft dollars in connection with the Funds. The Board concluded that the character and amount of potential indirect benefits to the Advisor were not unreasonable.

Based on all of the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreement continue to be fair and reasonable and that the continuation of the Agreement is in the best interests of each Fund. No single factor was determinative in the Board’s analysis.

Remuneration Disclosure Under the Alternative Investment Fund Managers Directive

First Trust Advisors L.P. (“First Trust”) is authorised and regulated by the U.S. Securities and Exchange Commission and is entitled to market shares of certain First Trust Exchange-Traded Fund IV funds it manages (the “Funds”) in certain member states in the

First Trust Exchange-Traded Fund IV

July 31, 2026 (Unaudited)

European Economic Area in accordance with the cooperation arrangements in Article 42 of the Alternative Investment Fund Managers Directive (the “Directive”). First Trust is required under the Directive to make disclosures in respect of remuneration. The following disclosures are made in line with First Trust’s interpretation of currently available regulatory guidance on remuneration disclosures.

During the year ended December 31, 2025, the amount of remuneration paid (or to be paid) by First Trust Advisors L.P. in respect of the Funds is $1,159,188. This figure is comprised of $63,957 paid (or to be paid) in fixed compensation and $1,095,231 paid (or to be paid) in variable compensation. There were a total of 26 beneficiaries of the remuneration described above. Those amounts include $275,639 paid (or to be paid) to senior management of First Trust Advisors L.P. and $883,549 paid (or to be paid) to other employees whose professional activities have a material impact on the risk profiles of First Trust Advisors L.P. or the Funds (collectively, “Code Staff”).

Code Staff included in the aggregated figures disclosed above are rewarded in line with First Trust’s remuneration policy (the “Remuneration Policy”) which is determined and implemented by First Trust’s senior management. The Remuneration Policy reflects First Trust’s ethos of good governance and encapsulates the following principal objectives:

to provide a clear link between remuneration and performance of First Trust and to avoid rewarding for failure;

ii.

to promote sound and effective risk management consistent with the risk profiles of the funds managed by First Trust; and

iii.

to remunerate staff in line with the business strategy, objectives, values and interests of First Trust and the funds managed by First Trust in a manner that avoids conflicts of interest.

First Trust assesses various risk factors which it is exposed to when considering and implementing remuneration for Code Staff and considers whether any potential award to such person(s) would give rise to a conflict of interest. First Trust does not reward failure, or consider the taking of risk or failure to take risk in its remuneration of Code Staff.

First Trust assesses performance for the purposes of determining payments in respect of performance-related remuneration of Code Staff by reference to a broad range of measures including (i) individual performance (using financial and non-financial criteria), and (ii) the overall performance of First Trust. Remuneration is not based upon the performance of the Funds.

The elements of remuneration are balanced between fixed and variable and the senior management sets fixed salaries at a level sufficient to ensure that variable remuneration incentivises and rewards strong individual performance but does not encourage excessive risk taking.

No individual is involved in setting his or her own remuneration.

Federal Tax Information

Distributions paid to foreign shareholders during each Fund’s fiscal year ended July 31, 2026 that were properly designated by each Fund as “interest-related dividends” or “short-term capital gain dividends,” may not be subject to federal income tax provided that the income was earned directly by such foreign shareholders.

Of the ordinary income (including short-term capital gain) distributions made by each Fund during the fiscal year ended July 31, 2026, none qualify for the corporate dividends received deduction available to corporate shareholders or as qualified dividend income.
