As I'm writing this letter in mid-November, it strikes me that things appear to be a little more chaotic in the current climate than normal. One of the things that may have contributed to the chaotic nature of the news flow of late was the November mid-term election. For the most part, except for a few seats in Congress, the election is behind us. We learned there would be no "red wave" (Republicans gaining a strong majority in Congress) but likely gridlock ahead. Gridlock has been good for stock market investors in the past few decades, particularly when there's been a Democratic president and the Republicans have control of at least one house of Congress, according to Brian Wesbury, Chief Economist at First Trust. The Federal Reserve (the "Fed") has kept its promise to aggressively hike interest rates to combat robust inflation. As of November 13, 2022, the Fed has increased the Federal Funds target rate (upper bound) six times, from 0.25% to 4.00%. The Fed's actions have some investors and pundits looking for evidence linking the interest rate hikes to a downturn in the economy. In short, the hope is that a pullback in economic activity might deter the Fed from executing further interest rate hikes. Fed Chairman Jerome Powell, however, recently said that the terminal rate (the ultimate rate the Fed is targeting) will likely need to be higher than previously estimated in order to curb stubbornly high inflation. The Consumer Price Index ("CPI") is a commonly used measure of inflation. The CPI stood at 7.7% on a trailing 12-month basis as of October 31, 2022, according to the U.S. Bureau of Labor Statistics. That is down from its recent high of 9.1% in June 2022. Prior to this year, the last time the CPI was higher than 7.0% was over 40 years ago. While monetary policy is an ongoing process subject to change, the Fed does appear to be steadfast in its mission to bring the rate of inflation back to its preferred level of 2.0%, and that will take some time, in my opinion. Stay tuned! Equity and fixed income markets have contended with numerous headwinds this year, such as the war between Russia and Ukraine. Since setting its all-time high of 4,796.56 on January 3, 2022, the S&P 500(R) Index has been in a bear market (a price decline of 20% or more from the most recent high) for the better part of 310 days. Suffice it to say, we are all looking forward to the end of this bear market. With respect to corrections and bear markets, the silver lining is that the S&P 500(R) Index has never failed to fully recover the losses sustained in any previous downturn. Where might we see demand for stocks moving forward? One such source could be stock buybacks. As of the last week of October 2022, U.S. companies had announced stock buybacks totaling $1 trillion so far this year, according to Birinyi Associates. The fixed income market has not been immune to selling pressure either. Year-to-date through November 10, 2022, yields on the 10-Year Treasury Note increased by 258 basis points. As you may be aware, bond yields and bond prices are inversely related, particularly with respect to investment-grade bonds. As yields rise, prices fall and vice versa. As noted above, the Fed has more work to do, so bond investors should not be surprised to see interest rates and bond yields trend at least a bit higher in the months ahead. 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, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P.

Under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in a portfolio of investment-grade debt securities issued or guaranteed by the U.S. government, its agencies or government-sponsored entities, including publicly-issued U.S. Treasury securities and mortgage-related securities. The Fund may also invest in exchange-traded funds ("ETFs") that principally invest in such securities. The Fund may purchase mortgage-related securities in "to-be-announced" transactions ("TBA Transactions"), including mortgage dollar rolls. ------------------------------------------------------------------------------------------------------------------------------------ PERFORMANCE ------------------------------------------------------------------------------------------------------------------------------------ AVERAGE ANNUAL CUMULATIVE TOTAL RETURNS TOTAL RETURNS 1 Year Ended Inception (1/22/19) Inception (1/22/19) 10/31/22 to 10/31/22 to 10/31/22 FUND PERFORMANCE NAV -21.37% -1.24% -4.60% Market Price -21.37% -1.24% -4.60% INDEX PERFORMANCE ICE BofA 5+ Year US Treasury Index -22.65% -2.06% -7.55% ------------------------------------------------------------------------------------------------------------------------------------ Total returns for the periods 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 period 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 SEC 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 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.

(2) 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.

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

Page 4 -------------------------------------------------------------------------------- PORTFOLIO COMMENTARY -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) ANNUAL REPORT OCTOBER 31, 2022 (UNAUDITED) ADVISOR First Trust Advisors L.P. ("First Trust" or the "Advisor") is the investment advisor to the First Trust Long Duration Opportunities ETF (the "Fund" or "LGOV"). First Trust is responsible for the selection and ongoing monitoring of the securities in the Fund's portfolio and certain other services necessary for the management of the portfolio. PORTFOLIO MANAGEMENT TEAM JAMES SNYDER - SENIOR VICE PRESIDENT AND SENIOR PORTFOLIO MANAGER JEREMIAH CHARLES - SENIOR VICE PRESIDENT AND SENIOR PORTFOLIO MANAGER The portfolio managers are primarily and jointly responsible for the day-to-day management of the Fund. Each portfolio manager has served as part of the portfolio management team of the Fund since 2019. COMMENTARY The Fund's primary investment objective is to generate current income with a focus on preservation of capital. Under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in a portfolio of investment-grade debt securities issued or guaranteed by the U.S. government, its agencies or government-sponsored entities, including publicly-issued U.S. Treasury securities and mortgage-related securities. MARKET RECAP The 12-month period ended October 31, 2022 began with markets coming under pressure as measures of inflation began to accelerate upward, and market participants questioning whether inflation was truly transitory, as so proclaimed by the Federal Reserve (the "Fed"). In a continuation of the yield curve repricing following the September 2021 Federal Open Market Committee meeting, bond yields once again resumed their march higher as the calendar year flipped into 2022, as fears of the COVID-19 variant, Omicron, were pushed aside, broader economic data remained strong, and incoming inflation data was rapidly deteriorating. Finally, the Fed relented and abandoned its transitory language, began to pivot and signaled very hawkish monetary policy to come. This hawkish pivot included guidance on not only an aggressive path of future interest rate hikes, but also signaled the use of the balance sheet to finally conclude new purchases of U.S. Treasuries and Agency mortgage-backed securities ("MBS") and subsequently, to let the securities mature and roll off via Quantitative Tightening. Unfortunately for the Fed and the broader U.S. economy, inflationary readings continued to push higher and the Fed was forced, albeit, in our opinion, clearly too late in its action, to act very aggressively. This started in June 2022 with the first 75 basis point ("bps") hike in nearly 30 years and was followed by successive 75 bps hikes at the Fed's July and September 2022 meetings. This abrupt monetary policy change kicked off rather sharp moves higher in interest rates, volatility, and risk asset pricing, with each coming under duress throughout the 2022 calendar year. Over the course of the 12-month period ended October 31, 2022, 2-Year Treasury yields rose +399 bps, the 5-Year Treasury yield rose +305 bps, and the 10-Year yield rose +243 bps. These dramatic interest rate increases caused measures of volatility to spike, with the Merrill Lynch Option Volatility Estimate Index increasing to levels not seen since the Great Financial Crisis of 2008-09. With upward pressure in rates and sustained interest rate volatility, overall risk asset pricing and market liquidity have come under significant pressure. Over the period, securitized spreads have widened with the Agency mortgage basis closing at +175 bps on October 31, 2022, which is +111 bps wider and the Government Option-Adjusted Spread on Agency MBS widening 45 bps to close the period at 49 bps, with a period high of 64 bps. PERFORMANCE ANALYSIS For the 12-month period ended October 31, 2022, the Fund returned -21.37%, net of fees, on a net asset value ("NAV") basis. For the same period, the ICE BofA 5+ Year US Treasury Index (the "Index") returned -22.65%. During the same period, the Fund outperformed the Index by 1.28% net of fees, on a NAV basis. Given the 2020-2021 historic ascent of home price appreciation and correspondingly, measures of inflation, the Fund elected to strategically run a lower overall effective duration. We remained mindful of the perceived logical response the Fed would be forced to counteract such purchasing power destruction, and as such maintained this very defensive posture on interest rates throughout the year. To help maintain this lower duration, the Fund utilizes derivatives, predominantly in treasury futures and options. The Fund uses these in both long and short positions, to manage both its overall interest rate exposure, and its key rate or duration exposure by maturity point along the yield curve. Additionally, the Fund uses long treasury futures to gain exposure to the U.S. government interest rates market. Since the Fund uses futures in Page 5 -------------------------------------------------------------------------------- PORTFOLIO COMMENTARY (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) ANNUAL REPORT OCTOBER 31, 2022 (UNAUDITED) such a way, and interest rates are higher on the year, the use of futures has contributed to the negative total return of the Fund over the 12-month period ended October 31, 2022. However, active management of duration, curve and volatility exposures using these instruments has contributed to the relative outperformance versus the benchmark. Given the positively convex attributes of Agency commercial mortgage-backed securities, and the team's favorable view on multifamily fundamentals, the Fund maintained a significant allocation to the sector. Additionally, the team has also looked to improve liquidity, and as such, reduced its Agency collateralized mortgage obligation holdings, and reallocated to U.S. Treasury and Treasury futures positions, alongside an increase in using the Agency MBS TBA Dollar Roll market. We felt that this was a prudent reallocation of risk to improve liquidity. Combined, these strategies helped to drive the relative outperformance, where the Fund outperformed the Index by over 125 bps, net of fees, on a NAV basis calendar year-to-date. MARKET OUTLOOK As expected, on the back of a massive increase in M2 money supply, limited housing inventory coupled with historically low rates, ongoing supply chain delays and labor market shortages, inflationary pressure built to levels not seen in 40 years. We remain mindful of both how hard it can be to tame inflation once set in, and the impacts this can have on term premium pricing along the U.S. yield curve. And while we believe that it won't be a straight line, we expect yields across the curve will continue to move higher, albeit at a much slower pace than experienced earlier this year. We believe the Fed may be forced to hike interest rates higher than the market expects, and as such believe that the curve inversion will continue to persist, although we do not expect significantly deeper inversion. Inflation remains high, however we believe the aggressive rate hikes implemented over the last several months have just begun to work their way through the broader economy, and already, it appears the housing market is beginning to cool off as month over month home price appreciation has turned negative. Currently, we do not believe the Fed will be an outright seller of its MBS holdings for long as measures of volatility and illiquidity remain this elevated. We do anticipate that heightened levels of rate volatility will remain over the shorter term, however, to expect measures of rate volatility and spread pricing to simply return to post-GFC/pre-COVID-19 levels in the near term and perhaps even intermediate term, would be unrealistic, in our view. Heavy handed Fed intervention appears to be over; for as long as inflation persists, the Fed appears committed to the fight. Despite the moderately bearish tone on rates, spreads are quite wide, and we believe opportunities abound, as we are now very positive on generic Agency MBS spread valuations. We remain committed to finding value across the various sectors of the mortgage market, but also along the term spectrum of the U.S. yield curve. Given the massive increase in rates this year, we have begun to increase the interest rate sensitivity in the Fund as duration risks appear to be more balanced than earlier in the year, and should yields continue to climb, we will likely continue to extend duration. We remain committed to actively managing the convexity component in the portfolio; meaning we do not want to extend in duration as rates rise, and conversely, we do not want to shorten or lose duration into a rally. From an asset allocation perspective, we plan to take advantage of very wide spreads in select securitized opportunities that the managers find to be attractively priced, mindful of overall market and Fund liquidity constraints. In our view, this approach would provide higher current income, total return, and spread protection for shareholders. We believe this strategy can be very effective with proper security selection, particularly when combined with appropriate yield curve management. We plan to continue to maintain a tradeable portfolio as that is critical to being able to act should opportunities arise. Page 6 FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) UNDERSTANDING YOUR FUND EXPENSES OCTOBER 31, 2022 (UNAUDITED) As a shareholder of First Trust Long Duration Opportunities 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, 2022. 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.

Page 14 See Notes to Financial Statements -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 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 ("SEC") under the Investment Company Act of 1940, as amended (the "1940 Act"). The Trust currently consists of twelve funds that are offering shares. This report covers the First Trust Long Duration Opportunities ETF (the "Fund"), which trades under the ticker "LGOV" on the NYSE Arca, Inc. ("NYSE Arca"). 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 primary investment objective is to generate current income with a focus on preservation of capital. The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its net assets (including investment borrowings) in a portfolio of investment-grade debt securities issued or guaranteed by the U.S. government, its agencies or government-sponsored entities, including publicly-issued U.S. Treasury securities and mortgage-related securities. The Fund may also invest in ETFs that principally invest in such securities. The Fund's investments in mortgage-related securities may include investments in fixed or adjustable-rate securities structured as "pass-through" securities and collateralized mortgage obligations, including residential and commercial mortgage-backed securities, stripped mortgage-backed securities and real estate mortgage investment conduits. The Fund will invest in mortgage-related securities issued or guaranteed by the U.S. government, its agencies (such as Ginnie Mae), and U.S. government-sponsored entities (such as Fannie Mae and Freddie Mac). The Fund may purchase government-sponsored mortgage-related securities in "to-be-announced" transactions ("TBA Transactions"), including mortgage dollar rolls. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Fund's portfolio managers. In addition to its investment in securities issued or guaranteed by the U.S. government, its agencies and government-sponsored entities, the Fund may invest up to 20% of its net assets in other types of debt securities, including privately-issued, non-agency sponsored asset-backed and mortgage-related securities, futures contracts, options, swap agreements, cash and cash equivalents, and ETFs that invest principally in fixed income securities. Further, the Fund may enter into short sales as part of its overall portfolio management strategy, or to offset a potential decline in the value of a security; however, the Fund does not expect, under normal market conditions, to engage in short sales with respect to more than 30% of the value of its net assets. Although the Fund intends to invest primarily in investment grade securities, the Fund may invest up to 20% of its net assets in securities of any credit quality, including securities that are below investment grade, which are also known as high yield securities, or commonly referred to as "junk" bonds, or unrated securities that have not been judged by the portfolio managers to be of comparable quality to rated investment grade securities. In the case of a split rating between one or more of the nationally recognized statistical rating organizations, the Fund will consider the highest rating. The Fund targets a weighted average effective duration of eight or more years. 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 Page 15 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 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: U.S. government securities, mortgage-backed securities, asset-backed securities and other debt securities are fair valued on the basis of valuations provided by a third-party pricing service approved by the Advisor's Pricing Committee, which may use the following valuation inputs when available: 1) benchmark yields; 2) reported trades; 3) broker/dealer quotes; 4) issuer spreads; 5) benchmark securities; 6) bids and offers; and 7) reference data including market research publications. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots. Securities traded in an over-the-counter market are valued at the mean of their most recent bid and asked price, if available, and otherwise at their last trade price. Common stocks and other equity securities listed on any national or foreign exchange (excluding The Nasdaq Stock Market LLC ("Nasdaq") and the London Stock Exchange Alternative Investment Market ("AIM")) are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the primary exchange for such securities. Shares of open-end funds are valued based on NAV per share. Exchange-traded futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded futures contracts are valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Exchange-traded options contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded options contracts are valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Fixed income and other debt securities having a remaining maturity of sixty days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor's Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following: 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. 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 Page 16 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 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) the fundamental business data relating to the issuer; 3) an evaluation of the forces which influence the market in which these securities are purchased and sold; 4) the type, size and cost of a security; 5) the financial statements of the issuer, or the financial condition of the country of issue; 6) the credit quality and cash flow of the issuer, or country of issue, based on the Pricing Committee's, sub-adviser's or portfolio manager's analysis, as applicable, or external analysis; 7) the information as to any transactions in or offers for the security; 8) the price and extent of public trading in similar securities of the issuer/borrower, or comparable companies; 9) the coupon payments; 10) the quality, value and salability of collateral, if any, securing the security; 11) the business prospects of the issuer, including any ability to obtain money or resources from a parent or affiliate and an assessment of the issuer's management (for corporate debt only); 12) the prospects for the issuer's industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry (for corporate debt only); and 13) 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: o 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. o 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. o 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, 2022, is included with the Fund's Portfolio of Investments. In December 2020, the SEC adopted Rule 2a-5 under the 1940 Act, establishing requirements to determine fair value in good faith for purposes of the 1940 Act. The rule permits fund boards to designate a fund's investment adviser to perform fair value determinations, subject to board oversight and certain other conditions. The rule also defines when market quotations are "readily available" for purposes of the 1940 Act and requires a fund to fair value a portfolio investment when a market quotation is not readily available. The SEC also adopted new Rule 31a-4 under the 1940 Act, which sets forth recordkeeping requirements associated with fair value determinations. The compliance date for Rule 2a-5 and Rule 31a-4 was September 8, 2022. Effective September 8, 2022 and pursuant to the requirements of Rule 2a-5, the Trust's Board of Trustees designated the Advisor as its valuation designee to perform fair value determinations and approved new Advisor Valuation Procedures for the Trust. 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. Page 17 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 The United Kingdom's Financial Conduct Authority (the "FCA"), which regulates the London Interbank Offered Rates ("LIBOR") announced on March 5, 2021 that it intended to phase-out all LIBOR reference rates, beginning December 31, 2021. Since that announcement, the FCA has ceased publication of all non-USD LIBOR reference rates and the 1-week and 2-month USD LIBOR reference rates as of December 31, 2021. The remaining USD LIBOR settings will cease to be published or no longer be representative immediately after June 30, 2023. The International Swaps and Derivatives Association, Inc. ("ISDA") confirmed that the FCA's March 5, 2021 announcement of its intention to cease providing LIBOR reference rates, constituted an index cessation event under the Interbank Offered Rates ("IBOR") Fallbacks Supplement and the ISDA 2020 IBOR Fallbacks Protocol for all 35 LIBOR settings and confirmed that the spread adjustment to be used in ISDA fallbacks was fixed as of the date of the announcement. In the United States, the Alternative Reference Rates Committee (the "ARRC"), a group of market participants convened by the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York in cooperation with other federal and state government agencies, has since 2014 undertaken efforts to identify U.S. dollar reference interest rates as alternatives to LIBOR and to facilitate the mitigation of LIBOR-related risks. In June 2017, the ARRC identified the Secured Overnight Financing Rate ("SOFR"), a broad measure of the cost of cash overnight borrowing collateralized by U.S. Treasury securities, as the preferred alternative for U.S. dollar LIBOR. The Federal Reserve Bank of New York began daily publishing of SOFR in April 2018. 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. The Fund invests in interest-only securities. For these securities, if there is a change in the estimated cash flows, based on an evaluation of current information, then the estimated yield is adjusted. Additionally, if the evaluation of current information indicates a permanent impairment of the security, the cost basis of the security is written down and a loss is recognized. Debt obligations may be placed on non-accrual status and the related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured. Securities purchased or sold on a when-issued, delayed-delivery or forward purchase commitment basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. The Fund maintains liquid assets with a current value at least equal to the amount of its when-issued, delayed-delivery or forward purchase commitments until payment is made. At October 31, 2022, the Fund had no when-issued, delayed-delivery securities, or forward purchase commitments. C. SHORT SALES Short sales are utilized to manage interest rate and spread risk, and are transactions in which securities or other instruments (such as options, forwards, futures or other derivative contracts) are sold that are not currently owned in the Fund's portfolio. When the Fund engages in a short sale, the Fund must borrow the security sold short and deliver the security to the counterparty. Short selling allows the Fund to profit from a decline in a market price to the extent such decline exceeds the transaction costs and the costs of borrowing the securities. The Fund is charged a fee or premium to borrow the securities sold short and is obligated to repay the lenders of the securities. Any dividends or interest that accrues on the securities during the period of the loan are due to the lenders. A gain, limited to the price at which the security was sold short, or a loss, unlimited in size, will be recognized upon the termination of the short sale; which is effected by the Fund purchasing the security sold short and delivering the security to the lender. Any such gain or loss may be offset, completely or in part, by the change in the value of the long portion of the Fund's portfolio. The Fund is subject to the risk it may be unable to reacquire a security to terminate a short position except at a price substantially in excess of the last quoted price. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund. D. FUTURES CONTRACTS The Fund may purchase or sell (i.e., is long or short) exchange-listed futures contracts to hedge against changes in interest rates (interest rate risk). Futures contracts are agreements between the Fund and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If the Fund is not able to enter into an offsetting transaction, the Fund will continue Page 18 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 to be required to maintain margin deposits on the futures contract. When the contract is closed or expires, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed or expired. This gain or loss is included in "Net realized gain (loss) on futures contracts" on the Statement of Operations. Upon entering into a futures contract, the Fund must deposit funds, called margin, with its custodian in the name of the clearing broker equal to a specified percentage of the current value of the contract. Open futures contracts are marked-to-market daily with the change in value recognized as a component of "Net change in unrealized appreciation (depreciation) on futures contracts" on the Statement of Operations. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are included in "Variation margin" receivable or payable on the Statement of Assets and Liabilities. If market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the futures contract and may realize a loss. The use of futures contracts involves the risk of imperfect correlation in movements in the price of the futures contracts, interest rates and the underlying instruments. E. OPTIONS CONTRACTS In the normal course of pursuing its investment objective, the Fund may invest up to 20% of its net assets in derivative instruments in connection with hedging strategies. The Fund may invest in exchange-listed options on U.S. Treasury securities, exchange-listed options on U.S. Treasury futures contracts and exchange-listed U.S. Treasury futures contracts. The Fund uses derivative instruments primarily to hedge interest rate risk and actively manage interest rate exposure. The primary risk exposure is interest rate risk. The Fund may purchase (buy) or write (sell) put and call options on futures contracts and enter into closing transactions with respect to such options to terminate an existing position. A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price prior to the expiration of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. Prior to exercise or expiration, a futures option contract may be closed out by an offsetting purchase or sale of a futures option of the same series. When 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. When the Fund purchases (buys) an option, the premium paid represents the cost of the option, which is included in "Premiums paid on options contracts purchased" 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. The Fund uses options on futures contracts in connection with hedging strategies. Generally, these strategies are applied under the same market and market sector conditions in which the Fund uses put and call options on securities. The purchase of put options on futures contracts is analogous to the purchase of puts on securities so as to hedge the Fund's securities holdings against the risk of declining market prices. The writing of a call option or the purchasing of a put option on a futures contract constitutes a partial hedge against declining prices of securities which are deliverable upon exercise of the futures contract. If the price at expiration of a written call option is below the exercise price, the Fund will retain the full amount of the option premium which provides a partial hedge against any decline that may have occurred in the Fund's holdings of securities. If the price when the option is exercised is above the exercise price, however, the Fund will incur a loss, which may be offset, in whole or in part, by the increase in the value of the securities held by the Fund that were being hedged. Writing a put option or purchasing a call option on a futures contract serves as a partial hedge against an increase in the value of the securities the Fund intends to acquire. Realized gains and losses on written options are included in "Net realized gain (loss) on written options contracts" on the Statement of Operations. Realized gains and losses on purchased options are included in "Net realized gain (loss) on purchased options contracts" on the Statement of Operations. The Fund is required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Such margin deposits will vary depending on the nature of the underlying futures contract (and the related initial margin requirements), the current market value of the option and other futures positions held by the Fund. The Fund will pledge in a segregated account at the Fund's custodian, liquid assets, such as cash, U.S. government securities or other high-grade liquid debt obligations equal in value to the amount due on the underlying obligation. Such segregated assets will be marked-to-market daily, and additional assets will be pledged in the segregated account whenever the total value of the pledged assets falls below the amount due on the underlying obligation. The risks associated with the use of options on future contracts include the risk that the Fund may close out its position as a writer of an option only if a liquid secondary market exists for such options, which cannot be assured. The Fund's successful use of options on futures contracts depends on the Advisor's ability to correctly predict the movement in prices on futures contracts and the underlying instruments, which may prove to be incorrect. In addition, there may be imperfect correlation between the instruments being hedged and the futures contract subject to option. Page 19 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 F. INTEREST-ONLY SECURITIES An interest-only security ("IO Security") is the interest-only portion of a mortgage-backed security that receives some or all of the interest portion of the underlying mortgage-backed security and little or no principal. A reference principal value called a notional value is used to calculate the amount of interest due to the IO Security. IO Securities are sold at a deep discount to their notional principal amount. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of an IO Security will fall. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of an IO Security will rise. These securities, if any, are identified on the Portfolio of Investments. G. PRINCIPAL-ONLY SECURITIES A principal-only security ("PO Security") is the principal-only portion of a mortgage-backed security that does not receive any interest, is priced at a deep discount to its redemption value and ultimately receives the redemption value. Generally speaking, when interest rates are falling and prepayment rates are increasing, the value of a PO Security will rise. Conversely, when interest rates are rising and prepayment rates are decreasing, generally the value of a PO Security will fall. These securities, if any, are identified on the Portfolio of Investments. H. STRIPPED MORTGAGE-BACKED SECURITIES Stripped mortgage-backed securities are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each with a specified percentage of the underlying security's principal or interest payments. Mortgage-backed securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security known as an IO Security and all of the principal is distributed to holders of another type of security known as a PO Security. These securities, if any, are identified on the Portfolio of Investments. I. MORTGAGE DOLLAR ROLLS AND TBA TRANSACTIONS The Fund may invest, without limitation, in mortgage dollar rolls. The Fund intends to enter into mortgage dollar rolls only with high quality securities dealers and banks, as determined by the Fund's investment advisor. In a mortgage dollar roll, the Fund will sell (or buy) mortgage-backed securities for delivery on a specified date and simultaneously contract to repurchase (or sell) substantially similar (same type, coupon and maturity) securities on a future date. Mortgage dollar rolls are recorded as separate purchases and sales in the Fund. The Fund may also invest in TBA Transactions. A TBA Transaction is a method of trading mortgage-backed securities. TBA Transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA Transaction, the buyer and the seller agree on general trade parameters such as agency, settlement date, par amount and price. J. DIVIDENDS AND DISTRIBUTION TO SHAREHOLDERS Dividends from net investment income, if any, are declared and paid monthly by the Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized 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, 2022 and 2021 was as follows: Distributions paid from: 2022 2021 Ordinary income................................. $ 459,443 $ 1,088,250 Capital gains................................... -- -- Return of capital............................... 36,043 45,452 Page 20 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 As of October 31, 2022, the components of distributable earnings on a tax basis for the Fund were as follows: Undistributed ordinary income................... $ -- Accumulated capital and other gain (loss)....... (4,265,975) Net unrealized appreciation (depreciation)...... (2,782,758) K. 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 2019, 2020, 2021, and 2022 remain open to federal and state audit. As of October 31, 2022, 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, 2022, the Fund had non-expiring capital loss carryforwards available for federal income tax purposes of $4,265,975. 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, 2022, 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 Fund. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended October 31, 2022, the adjustments for the Fund were as follows: Accumulated Accumulated Net Realized Net Investment Gain (Loss) Income (Loss) on Investments Paid-in Capital -------------- -------------- --------------- $ (173,358) $ 173,358 $ -- As of October 31, 2022, 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: Gross Gross Net Unrealized Unrealized Unrealized Appreciation Tax Cost Appreciation (Depreciation) (Depreciation) -------------- -------------- --------------- --------------- $ 21,702,225 $ 48,425 $ (2,831,183) $ (2,782,758) L. EXPENSES Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (see Note 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 and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, pro rata share of fees and expenses attributable to investments in other investment companies ("acquired fund fees and expenses"), 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 Fund has agreed to pay First Trust an annual unitary management fee equal to 0.65% of its average daily net assets. 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 will 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 cost of purchases of U.S. Government securities and non-U.S. Government securities, excluding short-term investments, for the fiscal year ended October 31, 2022, were $18,101,630 and $0, 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, 2022, were $27,082,614 and $0, respectively. The cost of purchases to cover investments sold short and the proceeds of investments sold short were $1,020,703 and $1,020,703, respectively. For the fiscal year ended October 31, 2022, the Fund had no in-kind transactions. 5. DERIVATIVE TRANSACTIONS The following table presents the types of derivatives held by the Fund at October 31, 2022, the primary underlying risk exposure and the location of these instruments as presented on the Statement of Assets and Liabilities.

During the fiscal year ended October 31, 2022, the premiums for purchased options contracts opened were $3,132,372 and the premiums for purchased options contracts closed, exercised and expired were $2,974,398. During the fiscal year ended October 31, 2022, the premiums for written options contracts opened were $550,078 and the premiums for written options contracts closed, exercised and expired were $538,648. The Fund does not have the right to offset financial assets and financial liabilities related to futures and options contracts on the Statement of Assets and Liabilities. 6. 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 ("NSCC") 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 Page 23 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 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. 7. 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, 2024. 8. 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. 9. OTHER MATTERS By operation of law, the Fund now operates as a diversified open-end management investment company as defined in Section 5(b) of the 1940 Act. 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 was the following subsequent event: At a meeting on October 24, 2022, the Board of Trustees approved a breakpoint pricing arrangement for each of the series of the Trust, including the Fund. Pursuant to this arrangement, which is effective as of November 1, 2022, the management fee the Fund pays to First Trust, as investment manager, will be discounted as the Fund's net assets reach certain predefined levels. Page 24 -------------------------------------------------------------------------------- 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 of First Trust Long Duration Opportunities ETF (the "Fund"), a series of the First Trust Exchange-Traded Fund IV, including the portfolio of investments, as of October 31, 2022, the related statement of operations for the year then ended, the changes in net assets for each of the two years in the period then ended, the financial highlights for the years ended 2022, 2021, and 2020 and for the period from January 22, 2019 (commencement of operations) through October 31, 2019, 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, 2022, 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 ended, and the financial highlights for the years ended 2022, 2021, and 2020, and for the period from January 22, 2019 (commencement of operations) through October 31, 2019, 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 audit. 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 audit 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 audit 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 audit 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 audit 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, 2022, by correspondence with the custodian and brokers; when replies were not received from and brokers, we performed other auditing procedures. We believe that our audit provides a reasonable basis for our opinion. /s/ Deloitte & Touche LLP Chicago, Illinois December 21, 2022 We have served as the auditor of one or more First Trust investment companies since 2001.

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 Page 26 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 (UNAUDITED) 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 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. Page 27 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 (UNAUDITED) 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 the 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 the Fund's shares and result in increased market volatility. During any such events, the Fund's shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on the 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. Page 28 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 (UNAUDITED) 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. NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE ADVISORY AGREEMENT BOARD CONSIDERATIONS REGARDING APPROVAL OF CONTINUATION OF 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 Long Duration Opportunities ETF (the "Fund"). The Board approved the continuation of the Agreement for a one-year period ending June 30, 2023 at a meeting held on June 12-13, 2022. 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 18, 2022 and June 12-13, 2022, 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 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 18, 2022, 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 12-13, 2022 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. Page 29 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 (UNAUDITED) 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 noted that the Advisor's Securitized Products Group is responsible for the day-to-day management of the Fund's investments. The Board considered the background and experience of the members of the Securitized Products Group and noted the Board's prior meetings with members of the Group. The Board considered the Advisor's statement that it applies the same oversight model internally with its Securitized Products Group as it uses for overseeing external sub-advisors, including portfolio risk monitoring and performance review. In reviewing the services provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor's and 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 18, 2022 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 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 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 unitary fee rate 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 18, 2022 meeting, discussed with Broadridge its methodology for assembling peer groups and discussed with the Advisor limitations in creating peer groups for actively-managed ETFs, including that all peer funds in the Expense Group were open-end mutual funds, 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 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 the one-year period ended December 31, 2021 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 underperformed the Performance Universe median for the one-year period ended December 31, 2021 and outperformed the benchmark index for the one-year period ended December 31, 2021. 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 and noted the Advisor's statement that it believes that its expenses relating to providing advisory services to the Fund will likely increase during the next twelve months as the Advisor continues to build infrastructure and add new staff. The Board noted that any reduction in fixed costs associated with the management of the Fund would benefit the Advisor, but that the unitary fee structure provides a level of certainty in expenses for the Fund. 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, 2021 and the estimated profitability level for the Fund calculated by the Advisor based on such data, as well as complex-wide Page 30 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 (UNAUDITED) 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. BOARD CONSIDERATIONS REGARDING APPROVAL OF AMENDMENT TO THE INVESTMENT MANAGEMENT AGREEMENT The Board of Trustees of First Trust Exchange-Traded Fund IV (the "Trust"), including the Independent Trustees, unanimously approved the amendment (the "Amendment") of the Investment Management Agreement (the "Agreement") with First Trust Advisors L.P. (the "Advisor") on behalf of the First Trust Long Duration Opportunities ETF (the "Fund"). The Board approved the Amendment at a meeting held on October 24, 2022. As part of the review process, the Board reviewed information and had preliminary discussions with the Advisor regarding the proposed Amendment at meetings held on April 18, 2022, June 12-13, 2022 and September 18-19, 2022. Following those preliminary discussions, the Board requested and received information from the Advisor regarding the proposed Amendment, and that information was considered at an executive session of the Independent Trustees and their counsel held prior to the October 24, 2022 meeting, as well as at the October meeting. In reviewing the Amendment, the Board considered that the purpose of the Amendment is to modify the unitary fee rate for the Fund under the Agreement by introducing a breakpoint schedule pursuant to which the unitary fee rate paid by the Fund to the Advisor will be reduced as assets of the Fund meet certain thresholds. The Board noted the Advisor's representations that the quality and quantity of the services provided to the Fund by the Advisor under the Agreement will not be reduced or modified as a result of the Amendment, and that the obligations of the Advisor under the Agreement will remain the same in all respects. The Board noted that it, including the Independent Trustees, last approved the continuation of the Agreement for a one-year period ending June 30, 2023 at a meeting held on June 12-13, 2022. The Board noted that in connection with such approval it had determined, based upon the information provided, that the terms of the Agreement were fair and reasonable and that the continuation of the Agreement was 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. Based on all of the information considered, the Board, including the Independent Trustees, unanimously determined that the terms of the Amendment are fair and reasonable and that the Amendment is in the best interests of the Fund.

Page 31 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 (UNAUDITED) 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 Page 32 -------------------------------------------------------------------------------- BOARD OF TRUSTEES AND OFFICERS -------------------------------------------------------------------------------- FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV) OCTOBER 31, 2022 (UNAUDITED) The following tables identify the Trustees and Officers of the Trust.
