Shareholder Letter
First Trust Enhanced Short Maturity ETF (FTSM)
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 First Trust Enhanced Short Maturity 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)
First Trust Enhanced Short Maturity ETF (FTSM)
The First Trust Enhanced Short Maturity ETF’s (the “Fund”) investment objective is to seek current income, consistent with preservation of capital and daily liquidity. Under normal market conditions, the Fund intends to achieve its investment objective by investing at least 80% of its net assets in a portfolio of U.S. dollar-denominated fixed- and variable-rate debt securities, including securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or U.S. government-sponsored entities, residential and commercial mortgage-backed securities, asset-backed securities, U.S. corporate bonds, fixed income securities issued by non-U.S. corporations and governments, municipal obligations, privately issued securities and other debt securities bearing fixed or floating interest rates. The Fund may also invest in money market securities. Shares of the Fund are listed on Nasdaq, Inc. under the ticker symbol “FTSM.”
The Fund’s investment advisor, First Trust Advisors L.P. (the “Advisor”), selects securities for the portfolio by evaluating fixed income sectors and macro market trends while completing bottom-up analysis of individual securities. Portfolio securities are selected based upon relative value in the context of overall portfolio duration. Key inputs for the screens in the securities selection process include, but are not limited to, credit quality, yield, interest rate sensitivity and liquidity. The Fund’s holdings are systematically monitored for meaningful changes in performance and risk measures. A security will generally be sold when the Advisor believes that a security can be substituted for a similar investment that represents better relative value; it lacks adequate compensation for embedded credit risk; or when rebalancing the portfolio to maintain diversification. Under normal market conditions, the Fund’s portfolio is expected to have an average duration of less than one year and an average maturity of less than three years.

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 the Securities and Exchange Commission’s 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. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund’s NAV was 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 index does not actually hold a portfolio of securities and therefore does 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 index. 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.

The ratings are by S&P Global Ratings. A credit rating is an assessment provided by a nationally recognized statistical rating organization
(NRSRO) of the creditworthiness of an issuer with respect to debt obligations. Ratings are measured highest to lowest on a scale that generally
ranges from AAA to D for long-term ratings and A-1+ to C for short-term ratings. Investment grade is defined as those issuers that have a long-
term credit rating of BBB- or higher or a short-term credit rating of A-3 or higher. The credit ratings shown relate to the credit worthiness of the
issuers of the underlying securities in the Fund, and not to the Fund or its shares. U.S. Treasury and U.S. Agency mortgage-backed securities
appear under “Government & Agency.” Credit ratings are subject to change.

Commentary
The Fund is an actively managed exchange-traded fund that seeks current income, consistent with preservation of capital and daily liquidity.
Market Recap
At the beginning of the 12-month period ended October 31, 2023, inflation remained stubbornly elevated with the November 2022 Consumer Price Index (“CPI”) printing 7.1%. At the same time, the Federal Reserve (the “Fed”) continued to reiterate its commitment to bring inflation back to the 2.0% target rate. As of October 31, 2022, the Fed had just increased the Federal Funds target rate by 75 basis points (“bps”) in each of its last three Federal Open Market Committee (“FOMC”) meetings, shifting the upper bound of the Federal Funds target rate to 3.25%. And despite the equivalent of seventeen 25 bps rate increases in 2022, inflation consistently exceeded the Fed’s 2.00% stated inflation target as the labor market remained robust. Notably, at the December 2022 FOMC meeting, the Fed projected a higher-than-expected terminal Federal Funds target rate of 5.00-5.25%, indicating the Fed’s view that inflation would remain persistent. In sum, the Fed increased the Federal Funds target rate by 4.25% in 2022, while the 10-Year U.S. Treasury yield increased from 1.51% at the beginning of the year to 3.88% at year-end. As the result of such stark shifts in the Treasury market, negative returns permeated the bond market in 2022.
Inflation continued to run in excess of the Fed’s 2.0% target in the first quarter of 2023, as evidenced by the CPI printing 6.0% in February 2023. In response, the Fed raised its policy rate twice during the first quarter to 4.75%-5.00% while maintaining its terminal Federal Funds target rate of 5.00-5.25%. In early March, after a strong labor market report, the bond market expected a terminal Federal Funds target rate of 5.50-5.75%, higher than the Fed’s own “dot plot” projection. However, by quarter-end, investors had hastily reduced rate expectations amid chaos in the banking sector, pricing in a terminal Federal Funds target rate of 4.75-5.00%. Thus, in the first quarter of 2023, the market effectively moved from expecting as many as three more rate hikes in 2023, to as many as four rate cuts by January 2024.
The banking turmoil proved to be relatively brief, owing to liquidity support from the Fed. At the same time, inflation continued to be elevated and the labor market robust. This led the Fed to hike again at its May 2023 meeting and then held it unchanged in June at 5.00-5.25%. Forecasts for the Federal Funds target rate also rebalanced higher, with the peak terminal rate trading near 5.50%, and holding above 5.00% through June of 2024. As market expectations shifted, interest rates across the treasury curve continued to move higher, particularly on the short end of the curve where interest rates are most sensitive to Fed policy. While the S&P 500® Index traded near 4,500 at the end of the second quarter, nearly 1,000 points above its bottom in October 2022, the 2-Year/10-Year U.S. Treasury yield curve remained over 100 bps inverted, marking its steepest inversion since the 1980s. Further, the 3-Month/10-Year U.S. Treasury yield curve remained inverted, after initially inverting in November 2022.

Annual Report
October 31, 2023 (Unaudited)
The FOMC raised its target rate to 5.25-5.50% at its July 2023 meeting in a continued attempt to mitigate inflation. In response, the yield curve bear steepened (long-term rates increased faster than short term rates) in what would be a theme for the remainder of the reporting period. The highly anticipated Jackson Hole Fed conference in August 2023 did not deliver much new information and the ensuing uncertainty generated more rate volatility and weighed on risk assets. At its September 2023 meeting, the FOMC held its target rate steady and upwardly revised its economic growth outlook for both this year and next, while reducing its 2024 rate cut projection from 100 bps to 50 bps; this proved a catalyst for higher yields, spread volatility, and lower equity values in the concluding weeks of the reporting period. As the fourth quarter of 2023 commences, the market seemingly expects the Fed to hold rates at these higher levels further into the future. The market’s apparent expectation of a “soft landing” (no imminent recession) likely supports the recent rate move, as the absence of a recession suggests the potential for stronger, and more sustained, economic expansion, resulting in the need for higher interest rates for a longer period of time.
For the 12-month period ended October 31, 2023, the 10-Year U.S. Treasury yield increased 80 bps to 4.87%, the 2-Year U.S. Treasury yield increased 57 bps to 5.07%, and the 1-Year U.S. Treasury yield increased 82 bps to 5.45%. Commercial paper yields also rose on the back of Fed interest rate hikes. The average yield on 90-day Tier 1 commercial paper increased 119 bps to 5.62%.
Performance Analysis
The Fund returned 4.72% based on net asset value and 4.74% based on market price for the 12-month period ended October 31, 2023. This compares to the ICE BofA 0-1 Year U.S. Treasury Index’s (the “Benchmark”) return of 4.68%.
As a result of interest rate hikes from the Fed, yields on front-end securities, like those held by the Fund, are at the highest level since 2007. The income (yield) from these securities was the leading driver of the Fund’s return during the period. Compared to the Benchmark, the Fund’s allocation to corporate credit and securitized assets were primary drivers of relative performance. On the other hand, the Fund’s allocation to securities longer than one year to maturity, was a detractor from performance as interest rates rose. The allocations to corporate bonds, both fixed and floating-rate, and commercial mortgage-backed securities were leading sources of outperformance. The allocation to Treasurys and commercial paper detracted on a relative basis although the absolute return contribution from both sectors was very positive. Within corporate credit, industries delivering the best results were consumer cyclical, real estate investment trusts and communications while capital goods and basics were leading detractors. The Fund’s largest weights in corporate credit were in banking and consumer non-cyclical and the allocation to each was accretive to relative performance. From a rating quality perspective, BBB-rated bonds had better returns compared to those with an A rating due to better contribution from credit spread.
Throughout the reporting period, the Fund maintained a diversified allocation with an emphasis on securities having a high level of liquidity. Overall credit risk was kept low as the investment strategy focused on high quality, short-term holdings. The Fund’s weighted average maturity was kept around six months and effective duration approximately five months. By maintaining a low duration and low average maturity, the strategy successfully achieved its objective of seeking current income. By capturing rising interest rates, the Fund was able to raise its distribution rate during the period from an annualized rate of 3.2% to 4.9%.
Market and Fund Outlook
The investment team continues to capture yield through floating-rate securities, cash equivalents, and short-maturity fixed rate bonds within an interest rate managed framework. The investment team expects the Fed to stay the course, likely holding its policy rate around today’s range of 5.25-5.50%, with the possibility of an additional rate hike in 2023. The real 10-Year U.S. Treasury yield was 2.46% at the end of the reporting period. Higher real rates have historically placed pressure on the overall business cycle. Consequently, this hiking cycle is likely much closer to its end than its beginning, in our opinion. While the Fed may leak an additional hike into the market, we believe today’s fixed income markets are much more balanced when it comes to income and interest rate risk. Further, with interest rates at these elevated levels, the current bond math is significantly more supportive of future positive returns, in our opinion. Valuations in short maturity corporate bonds remain attractive, as market yields have shifted starkly higher, reaching levels well above average over the past two decades.
The investment team expects to extend the Fund’s duration where appropriate, while keeping corporate credit (both commercial paper and corporate bonds) as the largest exposure. The Fund will also seek to maintain its allocation to securitized debt (asset-backed securities/mortgage-backed securities) for diversification purposes, particularly when valuations present compelling opportunities relative to U.S. Treasuries and corporate bonds. As always, the focus will be in the senior part of the capital structure.

October 31, 2023 (Unaudited)
The investment team continues to favor more defensive areas of fixed income and continues to employ its bottom-up credit underwriting process alongside its rigorous approach to risk management. Durable sectors such as healthcare, software, and regulated utilities continue to present such defensive investment opportunities. We believe curve allocation should remain an important component of total return in the year ahead, as well as security selection and sector allocation. The investment team’s research process seeks to identify opportunities that offer the best risk/reward balance, with investment decisions predicated on data analysis and evidence-based conclusions. We believe the Fund is well positioned to add value relative to its Benchmark.

Understanding Your Fund Expenses
October 31, 2023 (Unaudited)
As a shareholder of First Trust Enhanced Short Maturity 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.

This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under
Rule 144A of the Securities Act of 1933, as amended, and may be resold in transactions exempt from registration, normally to
qualified institutional buyers. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined
to be liquid by First Trust Advisors L.P., the Fund’s advisor. Although market instability can result in periods of increased overall
market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require
subjective judgment. At October 31, 2023, securities noted as such amounted to $457,257,953 or 6.1% of net assets.

(c)

First Trust Enhanced Short Maturity ETF (FTSM)
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 exchange-traded funds that are offering shares. This report covers the First Trust Enhanced Short Maturity ETF (the “Fund”), a diversified series of the Trust, which trades under the ticker “FTSM” on Nasdaq, Inc. 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 is an actively managed exchange-traded fund (“ETF”). The Fund’s investment objective is to seek current income, consistent with preservation of capital and daily liquidity. Under normal market conditions, the Fund intends to achieve its investment objective by investing at least 80% of its net assets in a portfolio of U.S. dollar-denominated fixed- and variable-rate debt securities, including securities issued or guaranteed by the U.S. government or its agencies, instrumentalities or U.S. government-sponsored entities, residential and commercial mortgage-backed securities, asset-backed securities, U.S. corporate bonds, fixed income securities issued by non-U.S. corporations and governments, municipal obligations, privately issued securities and other debt securities bearing fixed or floating interest rates. The Fund may also invest in money market securities. The Fund may invest in investment companies, such as ETFs, that invest primarily in debt securities. The Fund intends to limit its investments in privately-issued, non-agency sponsored mortgage- and asset-backed securities to 20% of its net assets. The Fund may also invest up to 20% of its net assets in floating rate loans representing amounts borrowed by companies or other entities from banks and other lenders. A significant portion of these loans may be rated below investment grade or unrated. Floating rate loans held by the Fund may be senior or subordinate obligations of the borrower and may or may not be secured by collateral. Under normal market conditions, the Fund’s portfolio is expected to have an average duration of less than one year and an average maturity of less than three years. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.
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. Domestic debt securities and foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. 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:
Corporate bonds, corporate notes, U.S. government securities, mortgage-backed securities, asset-backed securities, certificates of deposit and other debt securities are fair valued on the basis of valuations provided by dealers who make markets in such securities or by a third-party pricing service approved by the Advisor’s Pricing Committee, which may use the following valuation inputs when available:

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.
Equity securities traded in an over-the-counter market are valued at the close price or the last trade price.
Commercial paper is 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:
 1)
the credit conditions in the relevant market and changes thereto;
 2)
the liquidity conditions in the relevant market and changes thereto;
 3)
the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);
 4)
issuer-specific conditions (such as significant credit deterioration); and
 5)
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.
Senior Floating-Rate Loan Interests (“Senior Loans”)(1) are not listed on any securities exchange or board of trade. Senior Loans are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market-makers exist. This market, while having grown substantially since its inception, generally has fewer trades and less liquidity than the secondary market for other types of securities. Some Senior Loans have few or no trades, or trade infrequently, and information regarding a specific Senior Loan may not be widely available or may be incomplete. Accordingly, determinations of the market value of Senior Loans may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of Senior Loans than for other types of securities. Typically, Senior Loans are valued using information provided by a third-party pricing service. The third-party pricing service primarily uses over-the-counter pricing from dealer runs and broker quotes from indicative sheets to value the Senior Loans. 
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 most recent price provided by a pricing service;
 2)
available market prices for the fixed-income security;
 3)
the fundamental business data relating to the borrower/issuer;
 4)
an evaluation of the forces which influence the market in which these securities are purchased and sold;
 5)
the type, size and cost of a security;

The terms “security” and “securities” used throughout the Notes to Financial Statements include Senior Loans.

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. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.
The United Kingdom’s Financial Conduct Authority (the “FCA”), which regulates the London Interbank Offered Rates (“LIBOR”), ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. The overnight and 12-month USD LIBOR settings permanently ceased as of June 30, 2023. The FCA announced that the 1-, 3- and 6-month USD LIBOR settings will continue to be published using a synthetic methodology to serve as a fallback for non-U.S. contracts until September 2024. In response to the discontinuation of LIBOR, investors have added fallback provisions to existing contracts for investments whose value is tied to LIBOR, with most fallback provisions requiring the adoption of the Secured Overnight Financing Rate (“SOFR”) as a replacement rate. There is no assurance that any alternative reference rate, including 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. At this time, it is not possible to predict the full impact of the elimination of LIBOR and the establishment of an alternative reference rate on the Fund or its investments.

C. 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 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 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
$326,355,459
$46,350,806
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
$(1,074,706
)
Accumulated capital and other gain (loss)
(14,455,601
)
Net unrealized appreciation (depreciation)
(26,972,988
)
D. 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 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 $14,455,601 of capital loss carryforwards available, 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 the Fund’s shareholders.
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
Page 32

Notes to Financial Statements (Continued)
First Trust Enhanced Short Maturity ETF (FTSM)
October 31, 2023 
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 Fund. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended October 31, 2023, there were no tax adjustments made to accumulated distributable earnings (loss) accounts due to differences between book and tax treatments.
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:
Tax Cost
Gross
Unrealized
Appreciation

E. Expenses
Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (see Note 3).
3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements
First Trust, the investment advisor to the Fund, 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 the Fund’s portfolio, managing the Fund’s business affairs and providing certain administrative services necessary for the management of the Fund.
Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust manages the investment of the Fund’s assets and is responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit, license fees and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses with the exception of those attributable to affiliated funds, 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, and extraordinary expenses. The annual unitary management fee payable by the Fund to First Trust for these services will be reduced at certain levels of the Fund’s net assets (“breakpoints”) and calculated pursuant to the following schedule:
Breakpoints
 
Fund net assets up to and including $2.5 billion
0.45000
%
Fund net assets greater than $2.5 billion up to and including $5 billion
0.43875
%
Fund net assets greater than $5 billion up to and including $7.5 billion
0.42750
%
Fund net assets greater than $7.5 billion up to and including $10 billion
0.41625
%
Fund net assets greater than $10 billion
0.40500
%
First Trust had contractually agreed to waive management fees of 0.10% (0.20% prior to March 1, 2023) of average daily net assets until June 1, 2023. At that point, the waiver agreement expired and was not renewed. During any period in which the waiver agreement was in effect, the Fund was not eligible for the breakpoints described above. Pursuant to a separate contractual agreement between the Trust, on behalf of the Fund, and First Trust, the management fees paid to First Trust will be reduced by the portion of the management fees earned by First Trust from the Fund for assets invested in other investment companies advised by First Trust. This contractual agreement shall continue until the earlier of (i) its termination at the direction of the Trust’s Board of Trustees or (ii) upon termination of the Fund’s management agreement with First Trust; however, it is expected to remain in place at least until March 1, 2024. First Trust does not have the right to recover the fees waived that are attributable to the assets invested in other investment companies advised by First Trust. During the fiscal year ended October 31, 2023, the Advisor waived fees of $7,022,099.
The Trust has multiple service agreements with The Bank of New York Mellon (“BNYM”). Under the service agreements, BNYM performs custodial, fund accounting, certain administrative services, and transfer agency services for the Fund. As custodian, BNYM is responsible for custody of the Fund’s assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of the Fund’s securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for the Fund. BNYM 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 Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.
4. Purchases and Sales of Securities
The costs of purchases of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the fiscal year ended October 31, 2023, were $821,179,727 and $2,708,663,757, respectively. The proceeds from sales and paydowns of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the fiscal year ended October 31, 2023 were $419,411,425 and $1,535,962,422, respectively. 
For the fiscal year ended October 31, 2023, the Fund had no in-kind transactions.
5. 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 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.
6. 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
Page 34

Notes to Financial Statements (Continued)

October 31, 2023 
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.
7. 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.
8. 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 First Trust Enhanced Short Maturity 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 five 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 five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.
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.

Federal Tax Information
Distributions paid to foreign shareholders during the Fund’s fiscal year ended October 31, 2023 that were properly designated by the 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 the Fund during the fiscal year ended October 31, 2023, none qualify for the corporate dividends received deduction available to corporate shareholders or as qualified dividend income.
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 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
Page 37

Additional Information (Continued)
First Trust Enhanced Short Maturity ETF (FTSM)
October 31, 2023 (Unaudited)
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 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.

October 31, 2023 (Unaudited)
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 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 Agreement
Board Considerations Regarding Approval of the Continuation of the Investment Management Agreement 
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 “Agreement”) with First Trust Advisors L.P. (the “Advisor”) on behalf of the First Trust Enhanced Short Maturity ETF (the “Fund”).  The Board approved the continuation of the Agreement 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 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, 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 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 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 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 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 17, 2023, 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 4–5, 2023 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 the 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 the Fund knowing that the Advisor manages the Fund and knowing the Fund’s unitary fee.
In reviewing the Agreement, 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 the Fund and reviewed all of the services provided by the Advisor to the Fund, as well as the background and experience of the persons responsible for such services.  The Board noted that the Fund is an actively-managed ETF and considered the background and experience of the persons responsible for the day-to-day management of the Fund’s investments.  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 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.  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 under the Agreement have been and are expected to remain satisfactory and that 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 Agreement for the services provided.  The Board considered that as part of the unitary fee the Advisor is responsible for the 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 noted that the Advisor had previously agreed to reduce the unitary fee to the extent of acquired fund fees and expenses of shares of investment companies advised by the Advisor that are held by the Fund.  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 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 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 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 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 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 comparing the Fund’s performance for periods ended December 31, 2022 to the performance of the funds in the Performance Universe and to that of a benchmark index.  Based on the information provided, the Board noted that the Fund outperformed the Performance Universe median and the benchmark index for the one-, three- and five-year periods ended December 31, 2022.
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 continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor to the 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 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, and noted that the Advisor does not utilize soft dollars in connection with the Fund.  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 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 First Trust Enhanced Short Maturity 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 $7,541,592. This figure is comprised of $595,768 paid (or to be paid) in fixed compensation and $6,945,824 paid (or to be paid) in variable compensation. There were a total of 28 beneficiaries of the remuneration described above. Those amounts include $1,378,623 paid (or to be paid) to senior management of First Trust Advisors L.P. and $6,162,969 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.
