Shareholder Letter
FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (KNG)
Annual Letter from the Chairman and CEO
October 31, 2023
Dear Shareholders,
First Trust is pleased to provide you with the annual report for the FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (the “Fund”), which contains detailed information about the Fund for the twelve months ended October 31, 2023.
The Bureau of Economic Analysis recently announced that U.S. real gross domestic product (“GDP”) grew by a staggering 4.9% in the third quarter of 2023 and is now up 2.9% on a year-over-year basis from where it stood in the third quarter of 2022. The most recent quarter’s GDP data represents the fastest growth rate for any quarter since 2014. Consumer spending, which rose by 4.0% over the period, was responsible for 2.7 percentage points of the total increase in GDP. Whether the consumer can keep up this pace of spending remains to be seen, especially given recent news that excess savings from the pandemic-era stimulus have likely been depleted. From a global perspective, the International Monetary Fund (“IMF”) notes that progress in fighting inflation has led to lower economic growth. In their October 2023 publication of the World Economic Outlook, the IMF projected that the growth in world economic output is expected to slow from 3.5% in 2022 to 2.9% in 2024. The economic growth in advanced economies is projected to plummet from 2.6% in 2022 to 1.4% in 2024.
In the notes to their September 2023 meeting, the Federal Open Market Committee revealed that they may need to keep interest rates “higher for longer” as they continue to battle stubbornly high inflation. As many investors are likely aware, a higher Federal Funds target rate can have deep implications for consumers, such as driving up the cost of borrowing for homes, automobiles, and other large purchases. The American consumer has yet to feel the full weight of those burdens, in my opinion. That said, the data reveals a different story among corporate America. S&P Global Market Intelligence reported that a total of 516 U.S. corporations filed for bankruptcy protection on a year-to-date basis through September 30, 2023, up from a total of 263 corporate bankruptcy filings over the same period last year. Higher interest rates and Treasury bond yields have also sapped demand for commercial property loans. Data from Trepp, LLC, a leading provider of data and analytics to the commercial real estate and banking markets, revealed that just $28.2 billion of loans converted into commercial mortgage-backed securities have been issued in 2023, the lowest figure since 2011.
The financial markets battled a myriad of headwinds over the past year, from geopolitical uncertainty resulting from war (the conflicts between Israel and Hamas and Russia and Ukraine), to slowing global economic growth and sticky inflation. Brian Wesbury, Chief Economist at First Trust, notes that a U.S. economic recession is likely to begin at some point early next year. While calls for a recession may concern some investors, the following may offer solace. Data from Bloomberg reveals that the S&P 500® Index has posted positive total returns over the 3-year period following every recession since 1948.
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Fund again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

Fund Performance Overview (Unaudited)
FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (KNG)
The FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (the “Fund”) seeks investment results that correspond generally to the price and yield (before the Fund’s fees and expenses) of an equity index called the Cboe S&P 500® Dividend Aristocrats Target Income Index Monthly Series (the “Index”).
The Fund will normally invest at least 80% of its total assets (including investment borrowings) in the securities that comprise the Index. The Fund, using an indexing investment approach, attempts to replicate, before fees and expenses, the performance of the Index. The Index is owned, developed, maintained and calculated by S&P Opco, LLC (the “Index Provider”). The Index is a rules-based buy-write index designed with the primary goal of generating an annualized level of income from stock dividends and option premiums that is approximately 8% over the annual dividend yield of the S&P 500® Index and a secondary goal of generating capital appreciation. The Index’s objective to deliver a target level of income could result in the Fund selling securities to meet the target, which could make the Fund less tax-efficient than other ETFs. The Index is composed of two parts: (1) an equal-weighted portfolio of the stocks contained in the S&P 500® Dividend Aristocrats Index (the “Aristocrat Stocks”) that have options that trade on a national securities exchange and (2) a rolling series of short (written) call options on each of the Aristocrat Stocks (the “Covered Calls”). The S&P 500® Dividend Aristocrats Index includes companies in the S&P 500® Index that have increased dividend payments each year for at least 25 consecutive years and have a float adjusted market-cap of at least $3 billion as of the rebalancing reference date and have an average daily value traded of at least $5 million.

Total returns for the period since inception are calculated from the inception date of the Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.
The Fund’s per share net asset value (“NAV”) is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under Securities and Exchange Commission rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after its inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in the Fund at NAV and Market Price, respectively.
An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future performance.

Discussion of Fund Performance
This discussion is for the Fund (the Fund) for the 12-month period ended October 31, 2023 (the “current fiscal period”). The Fund seeks to track the Cboe S&P 500® Dividend Aristocrats Target Income Index Monthly Series (the “SPATI Index” or the Benchmark).
Market Recap
Equity markets showed remarkable resilience in late 2022 and the first half of 2023, followed by declines in the third quarter of 2023 as well as October of 2023 as inflation and recession fears resurfaced. The Federal Reserve (the “Fed”) responded to the increased inflation rate during the period by hiking the Federal Funds target rate from 3.25% to 5.5% by the end of the current fiscal period.
U.S. equities, as measured by the S&P 500® Index (the Index), gained 10.14%. Five of the eleven sectors within the Index were up during the period.  The top three sectors were the Communication Services, Information Technology, and Consumer Discretionary sectors, returning 35.7%, 30.9%, and 8.4%, respectively.  The bottom three sectors were the Utilities, Real Estate, and Health Care sectors, returning -7.7%, -6.6%, and -4.6%, respectively.
Performance Analysis
During the current fiscal period, the Fund generally held approximately equal weights in 67 stocks, as well as written call options on almost all of these stocks.  At the market close of July 21, 2023, the SPATI Index methodology updated from 3% to 8% per annum dividend yield in excess of the Index.
For the current fiscal period, the Fund’s net asset value (“NAV”) performance was -0.43%, while the SPATI Index performance was 0.38%. The underperformance of 0.81% can be explained by the following factors:
(1)
Fees and Expenses: Fees and expenses reduced the Fund’s performance by approximately 0.75%.
(2)
Execution Costs: Commissions, plus slippage due to trading securities at prices other than mid-market, reduced the Fund’s performance by approximately 0.06%.
(3)
Fund versus SPATI Index Holdings: While the Fund attempts to hold securities in the same proportion (i.e., weighting) as the SPATI Index, at times the Fund weights may deviate from the SPATI Index weights. The options positions may be “optimized” such that the Fund’s option weights are set to account for any liquidity concerns. That is, options that trade with wider bid-ask spreads may be excluded from the Fund holdings to minimize execution costs. For the current fiscal period, we estimate that the difference in weights between the Fund and the SPATI Index had a net 0.00% positive impact on the Fund’s performance.
Using market prices for the Fund, the Fund’s performance for the current fiscal period was -0.44%.

Annual Report
October 31, 2023 (Unaudited)
Impact of Fund Holdings on Performance
The top five performing holdings in the Fund for the current fiscal period were West Pharmaceutical Services, Pentair PLC, Linde PLC, A.O. Smith Corp., and W.W. Grainger, Inc., with returns of 38.7%, 37.4%, 30.4%, 29.7%, and 26.3%, respectively.
The bottom five performing holdings for the current fiscal period were Genuine Parts Co., Hormel Foods Corp., Target Corp., Walgreens Boots Alliance, Inc., and Albemarle Corp., with returns of -25.7%, -27.9%, -30.6%, -38.8%, and -54.4%, respectively.
Impact of Sector Weightings on Performance
For the current fiscal period, the Fund had sector weightings that were in line with the Benchmark, as the Fund seeks to track the SPATI Index.  However, the Fund’s sector weightings were substantially different than the sector weightings of the Index. Relative to the Index, the Fund was significantly overweight the Consumer Staples, Industrials, and Materials sectors, and was significantly underweight the Information Technology, Communication Services, and Consumer Discretionary sectors.  The net effect of the Fund’s sector weightings relative to the Index’s sector weightings negatively impacted the Fund’s performance relative to that of the Index.
Strong performances from the Fund’s holdings within the Industrials and Materials sectors, coupled with the Fund’s relative overweight in these sectors, contributed to relative overperformance for the Fund versus the Index.
Strong performance in the Information Technology sector, coupled with the Fund’s relative underweight in this sector, contributed to relative underperformance for the Fund versus the Index.
Market and Fund Outlook
During the current fiscal period, the Federal Reserve (the Fed) policy surrounding inflation remained a key driver of equity market performance.  Moving into the next fiscal year, this will continue to be a dominant theme, in our opinion. The 2024 U.S. presidential election will also be front and center in the upcoming year. Over the course of 2023, Technology stocks led broad based indices, as investors flocked to companies developing Artificial Intelligence capabilities. The failure of Silicon Valley Bank in March 2023 sent shockwaves throughout the banking system and rising energy prices over the summer contributed to higher inflation. In late October 2023, 30-year fixed mortgage rates peaked at 7.79%.  Investors are digesting a possible “higher for longer” period of sustained higher rates based on the Fed’s dot plot illustrating a median Federal Funds target rate of 5.1% for 2024, and 3.9% for 2025. Consumer Price Index inflation data has come down considerably, despite an unexpected 0.6% month-over-month reading in August 2023. The U.S. job market remains strong at 3.9% unemployment, with October 2023 marking the twenty-first straight month with unemployment below 4%. U.S. Gross domestic product has posted 5 consecutive positive quarters as it recorded growth of 4.9% in the third quarter of 2023, up from 2.1% in the second quarter of 2023.
The Fund generally holds equal weights in stocks within the Index that have increased their dividends for at least 25 consecutive years. We believe that the Fund is properly positioned to achieve its investment objective.

Understanding Your Fund Expenses
October 31, 2023 (Unaudited)
As a shareholder of FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (the “Fund”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.
The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended October 31, 2023.
Actual Expenses
The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this six-month period.
Hypothetical Example for Comparison Purposes
The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (KNG)
October 31, 2023 
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”).
The Trust currently consists of eighteen funds that are offering shares. This report covers the FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (the “Fund”), a diversified series of the Trust, which trades under the ticker “KNG” on Cboe BZX Exchange, Inc. (“Cboe BZX”). The Fund represents a separate series of shares of beneficial interest in the Trust. Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large blocks of shares known as “Creation Units.” 
The Fund’s investment objective seeks investment results that correspond generally to the price and yield (before the Fund’s fees and expenses) of an equity index called the Cboe S&P 500® Dividend Aristocrats Target Income Index Monthly Series (the “Index”). The Fund will normally invest at least 80% of its total assets (including investment borrowings) in the securities that comprise the Index. The Index is a rules-based buy-write index designed with the primary goal of generating an annualized level of income from stock dividends and option premiums that is approximately 8% over the annual dividend yield of the S&P 500® Index and a secondary goal of generating capital appreciation.
2. Significant Accounting Policies
The Fund is considered an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Fund 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
The 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. The Fund’s NAV is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.
The 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 Pricing Committee of the Fund’s 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. The Fund’s investments are valued as follows:
Common stocks 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.
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.
Equity securities traded in an over-the-counter market are valued at the close price or the last trade price.

October 31, 2023 
Shares of open-end funds are valued based on NAV per share.
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 the Fund’s NAV or make it difficult or 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:
 1)
the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price;
 2)
the type of security;
 3)
the size of the holding;
 4)
the initial cost of the security;
 5)
transactions in comparable securities;
 6)
price quotes from dealers and/or third-party pricing services;
 7)
relationships among various securities;
 8)
information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
 9)
an analysis of the issuer’s financial statements;
10)
the existence of merger proposals or tender offers that might affect the value of the security; and
11)
other relevant factors.
The Fund is 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 the Fund’s investments as of October 31, 2023, is included with the 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.

FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (KNG)
October 31, 2023 
C. Options Contracts
The Fund will employ a “partial covered call strategy,” meaning that covered calls will be typically written on a notional value less than the total value of each underlying stock contained in the S&P 500® Dividend Aristocrats Index (the “Aristocrat Stocks”), such that the short position in each call option is “covered” by a portion of the corresponding Aristocrat Stock held by the Fund, however, the notional value of the covered calls will not exceed 100% of the value of each underlying Aristocrat Stock. A written (sold) call option gives the seller the obligation to sell shares of the underlying asset at a specified price (“strike price”) at a specified date (“expiration date”). The writer (seller) of the call option receives an amount (premium) for writing (selling) the option. In the event the underlying asset appreciates above the strike price as of the expiration date, the writer (seller) of the call option will have to pay the difference between the value of the underlying asset and the strike price (which loss is offset by the premium initially received), and in the event the underlying asset declines in value, the call option may end up worthless and the writer (seller) of the call option retains the premium.
When the Fund writes (sells) an option, an amount equal to the premium received by the Fund is included in “Options contracts written, at value” on the Statement 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. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from options written. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. Any gain or loss on written options would be included in “Net realized gain (loss) on written options contracts” on the Statement of Operations. The Fund, as a writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option.
D. Dividends and Distributions to Shareholders
Dividends from net investment income of the 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 the Fund, if any, are distributed at least annually. The Fund may also designate a portion of the amount paid to redeeming shareholders as a distribution for tax purposes.
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 significantly modified portfolio securities held by the Fund 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.
The tax character of distributions paid during the fiscal years ended October 31, 2023 and 2022 was as follows:
Distributions paid from:
2023
2022
Ordinary income
$33,712,138

Capital gains

Return of capital
As of October 31, 2023, the components of distributable earnings on a tax basis for the Fund were as follows:
Undistributed ordinary income
$
Accumulated capital and other gain (loss)
Net unrealized appreciation (depreciation)
(158,883,403
)
E. Income Taxes
The 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
Page 18

Notes to Financial Statements (Continued)
FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (KNG)
October 31, 2023 
timing and amount of distributions, the Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of the Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.
The Fund is 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 years ended 2020, 2021, 2022, and 2023 remain open to federal and state audit. As of October 31, 2023, management has evaluated the application of these standards to the Fund and has determined that no provision for income tax is required in the Fund’s financial statements for uncertain tax positions.
The 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. The 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 October 31, 2023, for federal income tax purposes, the Fund had no capital loss carryforwards available, to the extent provided by regulations, to offset future capital gains.
Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended October 31, 2023, the Fund had no net late year ordinary or capital losses.
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 Statement 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 and in-kind transactions. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended October 31, 2023, the adjustments for the Fund were as follows:

Net Realized

As of October 31, 2023, 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:

6. Offsetting Assets and Liabilities
The Fund is subject to a Master Netting Arrangement, which governs the terms of certain transactions with select counterparties. The Master Netting Arrangement allows the Fund to close out and net its total exposure to a counterparty in the event of a default with respect to all the transactions governed under a single agreement with a counterparty. The Master Netting Arrangement also specifies collateral posting arrangements at pre-arranged exposure levels. Under the Master Netting Arrangement, collateral is routinely transferred if the total net exposure to certain transactions (net of existing collateral already in place) governed under the relevant Master Netting Arrangement with a counterparty in a given account exceeds a specified threshold depending on the counterparty and type of Master Netting Arrangement.

In some instances, the collateral amounts disclosed in the tables were adjusted due to the requirement to limit the collateral amounts to avoid the effect of overcollateralization. Actual collateral received/pledged may be more than the amounts disclosed herein.
7. Creations, Redemptions and Transaction Fees
The 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 the Fund or one of the Fund’s service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as “Creation Units.” Prior to the start of trading on every business day, the 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 the 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 the 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 the Fund’s shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of the Fund’s shares at or close to the NAV per share of the Fund.
The 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 the Fund times the number of
Page 21

Notes to Financial Statements (Continued)
FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (KNG)
October 31, 2023 
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.
The 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 the 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 the 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 Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Fund, 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 Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2025.
9. Indemnification
The Trust, on behalf of the Fund, 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 Fund 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.

Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Trustees of First Trust Exchange-Traded Fund IV:
Opinion on the Financial Statements and Financial Highlights
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (the “Fund”), one of the funds constituting the First Trust Exchange-Traded Fund IV, as of October 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the three years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of October 31, 2023, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the three years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. The financial highlights for the years ended October 31, 2020 and 2019 were audited by other auditors whose report dated December 23, 2020, expressed an unqualified opinion on such financial highlights.
Basis for Opinion
These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s 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 Fund 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 Fund 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 Fund’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 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 October 31, 2023, 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.

Risk Considerations
Risks are inherent in all investing. Certain general risks that may be applicable to a Fund are identified below, but not all of the material risks relevant to each Fund are included in this report and not all of the risks below apply to each Fund. The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information and other regulatory filings. Before investing, you should consider each Fund’s investment objective, risks, charges and expenses, and read each Fund’s prospectus and statement of additional information carefully. You can download each Fund’s prospectus at www.ftportfolios.com or contact First Trust Portfolios L.P. at (800) 621-1675 to request a prospectus, which contains this and other information about each Fund.
Concentration Risk. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund’s investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund’s corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified.
Credit Risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.
Cyber Security Risk. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund’s third-party service

October 31, 2023 (Unaudited)
providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches.
Defined Outcome Funds Risk. To the extent a fund’s investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor’s investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund’s share price will increase at the same rate as the enhanced returns sought by the fund, which is designed for an entire target outcome period. Trading flexible exchange options involves risks different from, or possibly greater than, the risks associated with investing directly in securities, such as less liquidity and correlation and valuation risks. A fund may experience substantial downside from specific flexible exchange option positions and certain positions may expire worthless.
Derivatives Risk. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivative. These risks are heightened when a fund’s portfolio managers use derivatives to enhance the fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund.
Equity Securities Risk. To the extent a fund invests in equity securities, the value of the fund’s shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.
ETF Risk. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF’s shares, or decisions by an ETF’s authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF’s shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads.
Fixed Income Securities Risk. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund’s fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund’s fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or “junk” bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities.
Index or Model Constituent Risk. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short
Page 25

October 31, 2023 (Unaudited)
period of time. As a result, a fund’s net asset value could be negatively impacted and the fund’s market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund’s shares.
Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.
Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.
LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR, has ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate (“SOFR”) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund.
Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.
Market Risk. Market risk is the risk that a particular security, or shares of a fund in general, may fall in value. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The COVID-19 global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets. While the U.S. has resumed “reasonably” normal business activity, many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. These events also adversely affect the prices and liquidity of a fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a fund’s shares and result in increased market volatility. During any such events, a fund’s shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on a fund’s shares may widen.
Non-U.S. Securities Risk. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction
Page 26

October 31, 2023 (Unaudited)
and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries.
Operational Risk. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect a fund’s ability to meet its investment objective. Although the funds and the funds’ investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
Passive Investment Risk. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets.
Preferred Securities Risk. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.
Valuation Risk. The valuation of certain securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial markets, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. A fund may hold investments in sizes smaller than institutionally sized round lot positions (sometimes referred to as odd lots). However, third-party pricing services generally provide evaluations on the basis of institutionally-sized round lots. If a fund sells certain of its investments in an odd lot transaction, the sale price may be less than the value at which such securities have been held by the fund. Odd lots often trade at lower prices than institutional round lots. There is no assurance that the fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the fund.

Advisory and Sub-Advisory Agreements
Board Considerations Regarding approval of the Continuation of the Investment Management Agreement and Sub-Advisory Agreements
The Board of Trustees of First Trust Exchange-Traded Fund IV (the “Trust”), including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement (the “Advisory Agreement”) with First Trust Advisors L.P. (the “Advisor”) on behalf of the FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF (the “Fund”) and the Investment Sub-Advisory Agreement (the “Sub-Advisory Agreement” and together with the Advisory Agreement, the “Agreements”) among the Trust, on behalf of the Fund, the Advisor and Cboe Vest Financial LLC (the “Sub-Advisor”).  The Board approved the continuation of the Agreements for a one-year period ending June 30, 2024 at a meeting held on June 4–5, 2023.  The Board determined that the continuation of the Agreements 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, 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 17, 2023 and June 4–5, 2023, the Board, including the Independent Trustees, reviewed materials provided by the Advisor and the Sub-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 and the Sub-Advisor to the Fund (including the relevant personnel responsible for these services and their experience); the unitary fee rate schedule payable by the 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 sub-advisory fee as compared to fees charged to other clients of the Sub-Advisor; the expense ratio of the Fund as compared to expense ratios of the funds in the Fund’s Expense Group and Expense Universe; performance information for the Fund, including comparisons of the 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 the Fund and the potential for the Advisor and the Sub-Advisor to realize economies of scale, if any; profitability and other financial data for the Advisor; financial data for the Sub-Advisor; any indirect benefits to the Advisor and its affiliates, First Trust Portfolios L.P. (“FTP”) and First Trust Capital Partners, LLC (“FTCP”), and the Sub-Advisor; and information on the Advisor’s and the Sub-Advisor’s compliance programs.  The Board reviewed initial materials with the Advisor at the meeting held on April 17, 2023, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor and the Sub-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 4–5, 2023 meeting, as well as at the June meeting.  The Board applied its business judgment to determine whether the arrangements between the Trust and the Advisor and among the Trust, the Advisor and the Sub-Advisor continue to be reasonable business arrangements from the Fund’s perspective.  The Board determined that, given the totality of the information provided with respect to the Agreements, the Board had received sufficient information to renew the Agreements.  The Board considered that shareholders chose to invest or remain invested in the Fund knowing that the Advisor and the Sub-Advisor manage the Fund and knowing the Fund’s unitary fee.
In reviewing the Agreements, the Board considered the nature, extent and quality of the services provided by the Advisor and the Sub-Advisor under the Agreements.  With respect to the Advisory Agreement, the Board considered that the Advisor is responsible for the overall management and administration of the Trust and the Fund and reviewed all of the services provided by the Advisor to the Fund, including the oversight of the Sub-Advisor, as well as the background and experience of the persons responsible for such services.  The Board noted that the Advisor oversees the Sub-Advisor’s day-to-day management of the Fund’s investments, 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, the Sub-Advisor’s and the Fund’s compliance with the 1940 Act, as well as the 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 Fund.  Finally, as part of the Board’s consideration of the Advisor’s services, the Advisor, in its written materials and at the April 17, 2023 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 Fund and the other funds in the First Trust Fund Complex.  With respect to the Sub-Advisory Agreement, the Board reviewed the materials provided by the Sub-Advisor and considered the services that the Sub-Advisor provides to the Fund, including the Sub-Advisor’s day-to-day management of the Fund’s investments.  In considering the Sub-Advisor’s management of the Fund, the Board noted the background and experience of the Sub-Advisor’s portfolio management team, including the Board’s prior meetings with members of the portfolio management team.  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 the Fund by the Advisor and the Sub-Advisor under the Agreements have been and are expected to remain satisfactory and that the Sub-Advisor, under the oversight of the Advisor, has managed the Fund consistent with its investment objective, policies and restrictions.
The Board considered the unitary fee rate schedule payable by the Fund under the Advisory Agreement for the services provided.  The Board noted that the sub-advisory fee is paid by the Advisor from the unitary fee.  The Board considered that as part of the unitary fee the Advisor is responsible for the Fund’s expenses, including the cost of sub-advisory, transfer agency, custody, fund administration, legal, audit and other services and license fees, if any, but excluding the fee payment under the Advisory Agreement and interest, taxes, 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 Group, as well as advisory and unitary fee rates charged by the Advisor and the Sub-Advisor to other fund (including ETFs) and non-fund clients, as applicable.  Because the Fund pays a unitary fee, the Board determined that expense ratios were the most relevant comparative data point.  Based on the information provided, the Board noted that the total (net) expense ratio for the Fund was above the median total (net) expense ratio of the peer funds in the Expense Group.  With respect to the Expense Group, the Board, at the April 17, 2023 meeting, discussed with Broadridge its methodology for assembling peer groups and discussed with the Advisor limitations in creating peer groups for index ETFs, including differences in underlying indexes and index-tracking methodologies that can result in greater management complexities across seemingly comparable ETFs, and different business models that may affect the pricing of services among ETF sponsors.  The Board also noted
Page 28

Additional Information (Continued)
FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (KNG)
October 31, 2023 (Unaudited)
that not all peer funds employ an advisor/sub-advisor management structure.  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 Fund and other non-ETF clients that limited their comparability.  In considering the unitary fee rate schedule 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 the Fund and the other funds in the First Trust Fund Complex.
The Board considered performance information for the Fund.  The Board noted the process it has established for monitoring the Fund’s performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor and the Sub-Advisor for the Fund.  The Board determined that this process continues to be effective for reviewing the Fund’s performance.  The Board received and reviewed information for periods ended December 31, 2022 regarding the performance of the Fund’s underlying index, the correlation between the Fund’s performance and that of its underlying index, the Fund’s tracking difference and the Fund’s excess return as compared to its benchmark index.  The Board noted that during 2023, it approved changes to the Fund’s investment strategy and that, effective on or about July 24, 2023, the Fund’s underlying index will increase its target income level from approximately 3% to approximately 8% over the annual dividend yield of the S&P 500® Index and the 20% notional value cap on covered call options written by the Fund’s underlying index will be removed.  Based on the information provided and its ongoing review of performance, the Board concluded that the Fund was correlated to its underlying index and that the tracking difference for the Fund was within a reasonable range.  In addition, the Board reviewed data prepared by Broadridge comparing the Fund’s performance to that of the Performance Universe and to that of a broad-based benchmark index.   However, given the Fund’s objective of seeking investment results that correspond generally to the performance of its underlying index, the Board placed more emphasis on its review of correlation and tracking difference.
On the basis of all the information provided on the unitary fee and performance of the Fund and the ongoing oversight by the Board, the Board concluded that the unitary fee for the Fund (out of which the Sub-Advisor is compensated) continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor and the Sub-Advisor to the Fund under the Agreements.
The Board considered information and discussed with the Advisor whether there were any economies of scale in connection with providing advisory services to the Fund at current asset levels and whether the Fund may benefit from any economies of scale.  The Board noted that the unitary fee rate schedule for the Fund 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 Fund will increase during the next twelve months as the Advisor continues to build infrastructure 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 Fund would benefit the Advisor, but that the unitary fee structure provides a level of certainty in expenses for shareholders of the Fund.  The Board concluded that the unitary fee rate schedule for the 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 the Fund for the twelve months ended December 31, 2022 and the estimated profitability level for the 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 the Fund was not unreasonable.  In addition, the Board considered indirect benefits described by the Advisor that may be realized from its relationship with the Fund.  The Board considered that the Advisor had identified as an indirect benefit to the Advisor and FTP their exposure to investors and brokers who, absent their exposure to the Fund, may have had no dealings with the Advisor or FTP.  The Board also noted that FTCP has a controlling ownership interest in the Sub-Advisor’s parent company and considered potential indirect benefits to the Advisor from such ownership interest.  The Board concluded that the character and amount of potential indirect benefits to the Advisor were not unreasonable.
The Board considered the Sub-Advisor’s statement that it believes that the sub-advisory fee for the Fund is appropriate.  The Board noted the Sub-Advisor’s statements that it continues to invest in infrastructure, technology and personnel, and that it anticipates that its expenses relating to providing services to the Fund will remain approximately the same for the next twelve months.  The Board noted that the Advisor pays the Sub-Advisor from the unitary fee and its understanding that the Fund’s sub-advisory fee was the product of an arm’s length negotiation.  The Board did not review the profitability of the Sub-Advisor with respect to the Fund.  The Board concluded that the profitability analysis for the Advisor was more relevant.  The Board considered the potential indirect benefits to the Sub-Advisor from being associated with the Advisor and the Fund, and noted the Sub-Advisor’s statements that it is the Sub-Advisor’s policy currently not to enter into soft-dollar arrangements for the procurement of research services in connection with client securities transactions and that, as a result, there are no foreseen indirect benefits from its relationship with the Fund.  The Board also

considered the potential indirect benefits to the Sub-Advisor from FTCP’s controlling ownership interest in the Sub-Advisor’s parent company.  The Board concluded that the character and amount of potential indirect benefits to the Sub-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 Agreements continue to be fair and reasonable and that the continuation of the Agreements is in the best interests of the Fund.  No single factor was determinative in the Board’s analysis.
Remuneration
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 funds it manages, including FT Cboe Vest S&P 500® Dividend Aristocrats Target Income ETF® (the “Fund”), in certain member states in the 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, 2022, the amount of remuneration paid (or to be paid) by First Trust Advisors L.P. in respect of the Funds is $238,569. This figure is comprised of $9,248 paid (or to be paid) in fixed compensation and $229,321 paid (or to be paid) in variable compensation. There were a total of 24 beneficiaries of the remuneration described above. Those amounts include $125,822 paid (or to be paid) to senior management of First Trust Advisors L.P. and $112,747 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:
i. 
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 Fund.
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.
