Forward-looking statements include statements regarding the goals, beliefs, plans or current expectations of First Trust Advisors L.P. ("First Trust" or the "Advisor") and/or Energy Income Partners, LLC ("EIP" or the "Sub-Advisor") and their respective representatives, taking into account the information currently available to them. Forward-looking statements include all statements that do not relate solely to current or historical fact. For example, forward-looking statements include the use of words such as "anticipate," "estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or other words that convey uncertainty of future events or outcomes. Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of any series of First Trust Exchange-Traded Fund IV (the "Trust") described in this report (each such series is referred to as a "Fund" and collectively, as the "Funds") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and/or Sub-Advisor and their respective representatives only as of the date hereof. We undertake no obligation to publicly revise or update these forward-looking statements to reflect events and circumstances that arise after the date hereof. PERFORMANCE AND RISK DISCLOSURE There is no assurance that any Fund described in this report will achieve its investment objective. Each Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund's shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in a Fund. See "Risk Considerations" in the Additional Information section of this report for a discussion of certain other risks of investing in the Funds. Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost. The Advisor may also periodically provide additional information on Fund performance on each Fund's webpage at www.ftportfolios.com.

Please note that the FT Energy Income Partners Strategy ETF was incepted on November 2, 2022, and so the information in this letter and the semi-annual report prior to that date does not apply to this Fund. It pleases me to write that on May 5, 2023, the World Health Organization officially declared that the coronavirus ("COVID-19") pandemic no longer qualified as a global health emergency. While the virus officially no longer poses an immediate threat, its full impact on the world economy remains to be seen, in my opinion. Recall, if you will, those early days of the pandemic; companies sent workers home, consumers were afraid or unwilling to leave their homes, supply chains dried up, and grocery shelves were left bare. Hoping to provide relief to their constituents and to bolster economic activity, governments across the globe funneled trillions of dollars in stimulus directly into the hands of their citizens. Unfortunately, economist Milton Friedman's age-old economic adage "there's no such thing as a free lunch" still holds. As a result of the U.S. government stimulus, gross domestic product rebounded quickly, but so did inflation. As many investors are aware, the Federal Reserve (the "Fed") has been locked in a battle with stubbornly high inflation for several years now. Inflation, as measured by the trailing 12-month rate of change in the Consumer Price Index ("CPI"), surged from 1.4% on December 31, 2020, to 9.1% as of June 30, 2022. Since then, the trailing rate on the CPI has come down, but remains elevated. On April 30, 2023, the CPI stood at 4.9%, well above the Fed's goal of 2.0%. Surging prices have not been restricted to the U.S. Headline inflation rates in each of the countries that make up the so-called Group of Ten (G-10) stand above the targets set by their central banks, according to data from Bloomberg. From the Fed's perspective, monetary policy is the most efficient means to combat rising prices. From December 31, 2020 through May 3, 2023, the Fed increased the Federal Funds target rate (upper bound) a total of ten times, raising the rate from 0.25% to 5.25%. As mentioned, tighter monetary policy resulted in a decrease in the CPI, but there have been casualties in the Fed's battle with rising prices. The most recent banking turmoil is one example. Another is the spike in mortgage rates. According to Bankrate, the national average for a 30-year mortgage stood at just 2.87% on December 31, 2020. As of May 1, 2023, the average 30-year mortgage rate had surged to 6.88%. Not all the news is negative, however. Driven by a strong U.S. labor market, consumer spending remained robust in April 2023. Notably, American corporations added 253,000 jobs during the month, and the unemployment rate stood at a 53-year low. Bob Carey, Chief Market Strategist at First Trust, recently summed up the current situation, noting that "we're not out of the woods yet." That said, even the most difficult situations don't last forever. In my opinion, like the COVID-19 pandemic, inflation, and the tighter monetary policy it ushered in, will pass with time. 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 Funds 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.

The Fund's investment objective is to seek total return. The Fund will invest, under normal market conditions, at least 80% of its net assets (including investment borrowings) in equity securities of companies deemed by Energy Income Partners, LLC ("EIP" or the "Sub-Advisor") to be engaged in the energy infrastructure sector. These companies principally include U.S. and Canadian natural gas and electric utilities, corporations operating energy infrastructure assets such as pipelines or renewable energy production, utilities, publicly-traded master limited partnerships or limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, and other companies that derive the majority of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "energy infrastructure companies"). The Fund will invest principally in energy infrastructure companies. Under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in equity securities of companies headquartered or incorporated in the United States and Canada. ------------------------------------------------------------------------------------------------------------------------------------ PERFORMANCE ------------------------------------------------------------------------------------------------------------------------------------ AVERAGE ANNUAL TOTAL RETURNS CUMULATIVE TOTAL RETURNS 6 Months 1 Year 5 Years 10 Years Inception 5 Years 10 Years Inception Ended Ended Ended Ended (6/20/12) Ended Ended (6/20/12) 4/30/23 4/30/23 4/30/23 4/30/23 to 4/30/23 4/30/23 4/30/23 to 4/30/23 FUND PERFORMANCE NAV 3.44% 5.36% 7.83% 5.06% 6.73% 45.78% 63.86% 102.86% Market Price 3.25% 5.25% 7.79% 5.06% 6.72% 45.54% 63.78% 102.76% INDEX PERFORMANCE Blended Benchmark(1) 3.53% 8.36% 9.97% 5.97% 7.46% 60.84% 78.54% 118.55% S&P 500(R) Index 8.63% 2.66% 11.45% 12.20% 13.07% 71.93% 216.22% 279.75% ------------------------------------------------------------------------------------------------------------------------------------ (See Notes to Fund Performance Overview on page 8.) ----------------------------- (1) The Blended Benchmark consists of the following two indices: 50% of the PHLX Utility Sector Index which is a market capitalization weighted index composed of geographically diverse public U.S. utility stocks; and 50% of the Alerian MLP Total Return Index which is a float-adjusted, capitalization weighted composite of the 27 most prominent energy Master Limited Partnerships (MLPs). Indices are unmanaged and an investor cannot invest directly in an index. All index returns assume that distributions are reinvested when they are received. The Blended Benchmark returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS Information showing the number of days the market price of the Fund's shares was greater (at a premium) and less (at a discount) than the Fund's net asset value for the most recently completed year, and the most recently completed calendar quarters since that year (or life of the Fund, if shorter) is available at https://www.ftportfolios.com/Retail/etf/home.aspx. Page 7 -------------------------------------------------------------------------------- NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- Total returns for the periods since inception are calculated from the inception date of each Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the periods indicated. "Cumulative Total Returns" represent the total change in value of an investment over the periods indicated. Each 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. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund's NAV is calculated. Since shares of each Fund did not trade in the secondary market until after the Fund's inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of each 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 each Fund at NAV and Market Price, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund's past performance is no guarantee of future performance.

Page 9 FIRST TRUST EXCHANGE-TRADED FUND IV UNDERSTANDING YOUR FUND EXPENSES APRIL 30, 2023 (UNAUDITED) As a shareholder of First Trust North American Energy Infrastructure Fund, First Trust EIP Carbon Impact ETF or FT Energy Income Partners Strategy ETF (each a "Fund" and collectively, the "Funds"), 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 Funds 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 (or since inception) and held through the six-month period (or shorter) ended April 30, 2023. ACTUAL EXPENSES The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period" to estimate the expenses you paid on your account during this six-month period (or shorter). HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line in the following table provides information about hypothetical account values and hypothetical expenses based on each Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each 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 Funds 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.

ORGANIZATION First Trust Exchange-Traded Fund IV (the "Trust") is an open-end management investment company organized as a Massachusetts business trust on September 15, 2010, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the "1940 Act"). The Trust currently consists of fourteen funds that are offering shares. This report covers the three funds (each a "Fund" and collectively, the "Funds") listed below. The shares of each Fund are listed and traded on the NYSE Arca, Inc. ("NYSE Arca"). First Trust North American Energy Infrastructure Fund - (ticker "EMLP") First Trust EIP Carbon Impact ETF - (ticker "ECLN") FT Energy Income Partners Strategy ETF - (ticker "EIPX")(1) (1) Commenced investment operations on November 2, 2022. Each Fund represents a separate series of shares of beneficial interest in the Trust. Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large blocks of shares known as "Creation Units." Each Fund is an actively managed exchange-traded fund. EMLP's investment objective is to seek total return. EMLP will invest, under normal market conditions, at least 80% of its net assets (including investment borrowings) in equity securities of companies deemed by Energy Income Partners, LLC ("EIP" or the "Sub-Advisor") to be engaged in the energy infrastructure sector, which principally include U.S. and Canadian natural gas and electric utilities, corporations operating energy infrastructure assets such as pipelines or renewable energy production, utilities, publicly-traded master limited partnerships or limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, and other companies that derive the majority of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "Energy Infrastructure Companies"). In addition, under normal market conditions, the Fund will invest at least 80% of its net assets (including investment borrowings) in equity securities of companies headquartered or incorporated in the United States and Canada. ECLN's investment objective is to seek to achieve a competitive risk-adjusted total return balanced between dividends and capital appreciation. ECLN will invest, under normal market conditions, at least 80% of its net assets (including investment borrowings) in the equity securities of companies identified by EIP as having or seeking to have a positive carbon impact. The Sub-Advisor defines positive carbon impact companies as companies that reduce, have a publicly available plan to reduce, or enable the reduction of carbon and other greenhouse gas emissions from the production, transportation, conversion, storage and use of energy. ECLN's investments will be concentrated in the industries constituting the energy infrastructure sector, which principally include utilities, natural gas pipeline companies, manufacturers, contracted developers and/or owners of renewable energy; and other companies that derive the majority of their earnings from manufacturing, operating or providing services in support of infrastructure assets and/or infrastructure activities such as renewable energy equipment, energy storage, carbon capture and sequestration, fugitive methane abatement and energy transmission and distribution equipment. EIPX's investment objective is to seek risk-adjusted total return. EIPX will invest, under normal market conditions, at least 80% of its net assets (plus any borrowing for investment purposes) in a portfolio of equity securities in the broader energy market ("Energy Companies"), which principally include companies in the Global Industry Classification Standard ("GICS") energy sector, companies in the GICS utility sector (excluding water utilities), or companies in any other GICS sectors that derive at least 50% of their revenues or profits from exploration, development, production, gathering, transportation, processing, storing, refining, distribution, mining or marketing, of natural gas, natural gas liquids (including propane), crude oil, refined petroleum products, petrochemicals, electricity, coal, uranium, hydrogen or other energy sources, renewable energy production, renewable energy equipment, energy storage, carbon, carbon dioxide, carbon dioxide and fugitive methane mitigation and management, as well as electric transmission, distribution, storage and system reliability support. Energy Companies also include companies providing engineering, consulting and construction services that derive at least 50% of their revenues or profits from the above, all of which are selected by EIP. These companies may include MLPs and MLP affiliates. 2. SIGNIFICANT ACCOUNTING POLICIES The Funds are each considered an investment company and follow 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 Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. Page 23 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) A. PORTFOLIO VALUATION Each Fund's NAV is determined daily as of the close of regular trading on the New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. Each Fund's NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding. Each Fund's investments are valued daily at market value or, in the absence of the 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 Funds' investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"), in accordance with valuation procedures approved by the Trust's Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. Each Fund's investments are valued as follows: Common stocks, MLPs 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. Securities trading on foreign exchanges or over-the-counter markets that close prior to the NYSE close may be valued using a systematic fair valuation model provided by a third-party pricing service. If these foreign securities meet certain criteria in relation to the valuation model, their valuation is systematically adjusted to reflect the impact of movement in the U.S. market after the close of the foreign markets. Shares of open-end funds are valued based on NAV per share. 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. Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor's Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund's NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security's fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following: 1) the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price; 2) the type of security; 3) the size of the holding; 4) the initial cost of the security; 5) transactions in comparable securities; 6) price quotes from dealers and/or third-party pricing services; 7) relationships among various securities; 8) information obtained by contacting the issuer, analysts, or the appropriate stock exchange; 9) an analysis of the issuer's financial statements; 10) the existence of merger proposals or tender offers that might affect the value of the security; and 11) other relevant factors. Page 24 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) If the securities in question are foreign securities, the following additional information may be considered: 1) the value of similar foreign securities traded on other foreign markets; 2) ADR trading of similar securities; 3) closed-end fund or exchange-traded fund trading of similar securities; 4) foreign currency exchange activity; 5) the trading prices of financial products that are tied to baskets of foreign securities; 6) factors relating to the event that precipitated the pricing problem; 7) whether the event is likely to recur; 8) whether the effects of the event are isolated or whether they affect entire markets, countries or regions; and 9) other relevant factors. Because foreign markets may be open on different days than the days during which investors may transact in the shares of a Fund, the value of the Fund's securities may change on the days when investors are not able to transact in the shares of the Fund. The value of securities denominated in foreign currencies is converted into U.S. dollars using exchange rates determined daily as of the close of regular trading on the NYSE. The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows 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 each Fund's investments as of April 30, 2023, is included with each Fund's Portfolio of Investments. B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income, if any, is recorded on the accrual basis. Distributions received from a Fund's investments in MLPs generally are comprised of return of capital and investment income. A Fund records estimated return of capital and investment income based on historical information available from each MLP. These estimates may subsequently be revised based on information received from the MLPs after their tax reporting periods are concluded. Distributions received from a Fund's investments in Real Estate Investment Trusts ("REITs") may be comprised of return of capital, capital gains, and income. The actual character of the amounts received during the year are not known until after the REITs' fiscal year end. A Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by a Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude. C. FOREIGN CURRENCY The books and records of the Funds are maintained in U.S. dollars. Foreign currencies, investments and other assets and liabilities are translated into U.S. dollars at the exchange rates prevailing at the end of the period. Purchases and sales of investments and items of income and expense are translated on the respective dates of such transactions. Unrealized gains and Page 25 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) losses on assets and liabilities, other than investments in securities, which result from changes in foreign currency exchange rates have been included in "Net change in unrealized appreciation (depreciation) on foreign currency translation" on the Statements of Operations. Unrealized gains and losses on investments in securities which result from changes in foreign exchange rates are included with fluctuations arising from changes in market price and are shown in "Net change in unrealized appreciation (depreciation) on investments" on the Statements of Operations. Net realized foreign currency gains and losses include the effect of changes in exchange rates between trade date and settlement date on investment security transactions, foreign currency transactions and interest and dividends received and is included in "Net realized gain (loss) on foreign currency transactions" on the Statements of Operations. The portion of foreign currency gains and losses related to fluctuations in exchange rates between the initial purchase settlement date and subsequent sale trade date is included in "Net realized gain (loss) on investments" on the Statements of Operations. D. DIVIDENDS AND DISTRIBUTION TO SHAREHOLDERS Dividends from net investment income of each Fund, if any, are declared and paid quarterly, or as the Board of Trustees may determine from time to time. Distributions of net realized gains earned by each Fund, if any, are distributed at least annually. A Fund may also designate a portion of the amount paid to redeeming shareholders as a distribution for tax purposes. Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on significantly modified portfolio securities held by the Funds and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future. The tax character of distributions paid by each Fund during the fiscal year ended October 31, 2022 was as follows: Distributions Distributions Distributions paid from paid from paid from Ordinary Income Capital Gains Return of Capital --------------- ------------- ----------------- First Trust North American Energy Infrastructure Fund $ 33,630,677 $ -- $ 41,548,643 First Trust EIP Carbon Impact ETF 331,016 -- -- As of October 31, 2022, the components of distributable earnings on a tax basis for each Fund were as follows: Accumulated Undistributed Capital and Net Unrealized Ordinary Other Appreciation Income Gain (Loss) (Depreciation) --------------- ------------- ----------------- First Trust North American Energy Infrastructure Fund $ -- $(358,055,801) $ 493,028,013 First Trust EIP Carbon Impact ETF 23,595 39,587 1,183,859 E. INCOME TAXES Each Fund intends to qualify or continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, each Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of each Fund's taxable income exceeds the distributions from such taxable income for the calendar year. Each Fund intends to utilize provisions of the federal income tax laws, which allow it to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. Each Fund is subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At October 31, 2022, EMLP and ECLN had non-expiring capital loss carryforwards available for federal income tax purposes of $358,055,801 and $0, respectively. Page 26 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) The Funds are subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. For EMLP and ECLN, the taxable years ended 2019, 2020, 2021, and 2022 remain open to federal and state audit. As of April 30, 2023, management has evaluated the application of these standards to the Funds and has determined that no provision for income tax is required in the Funds' financial statements for uncertain tax positions. During the taxable year ended October 31, 2022, EMLP and ECLN utilized non-expiring capital loss carryforwards in the following amounts: Capital Loss Carryforward Utilized --------------- First Trust North American Energy Infrastructure Fund $ 84,449,607 First Trust EIP Carbon Impact ETF 4,660 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, EMLP and ECLN had no net late year ordinary or capital losses. As of April 30, 2023, the aggregate cost, gross unrealized appreciation, gross unrealized depreciation, and net unrealized appreciation/(depreciation) on investments (including short positions and derivatives, if any) for federal income tax purposes were as follows: Gross Gross Net Unrealized Unrealized Unrealized Appreciation Tax Cost Appreciation (Depreciation) (Depreciation) --------------- --------------- --------------- --------------- First Trust North American Energy Infrastructure Fund $ 2,000,521,361 $ 491,309,918 $ (14,619,669) $ 476,690,249 First Trust EIP Carbon Impact ETF 34,321,267 2,446,373 (1,061,923) 1,384,450 FT Energy Income Partners Strategy ETF 118,820,827 3,757,233 (1,410,410) 2,346,823 F. EXPENSES Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (see Note 3). 3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS First Trust, the investment advisor to the Funds, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the ongoing monitoring of the securities in each Fund's portfolio, managing the Funds' business affairs and providing certain administrative services necessary for the management of the Funds. The Trust, on behalf of the Funds, and First Trust have retained EIP, an affiliate of First Trust, to serve as the Funds' investment sub-advisor. In this capacity, EIP is responsible for the selection and ongoing monitoring of the securities in each Fund's investment portfolio. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust will supervise EIP and its management of the investment of each Fund's assets and will pay EIP for its services as the Funds' sub-advisor. First Trust will also be responsible for each 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, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. Effective November 1, 2022, for EMLP and ECLN, and for EIPX from its date of inception, November 2, 2022, the annual unitary management fee payable by each Fund to First Trust for these services will be reduced at certain levels of each Fund's net assets ("breakpoints") and calculated pursuant to the schedule below: Breakpoints ------------------------------------------------------------------------- Fund net assets up to and including $2.5 billion 0.95000% Fund net assets greater than $2.5 billion up to and including $5 billion 0.92625% Fund net assets greater than $5 billion up to and including $7.5 billion 0.90250% Fund net assets greater than $7.5 billion up to and including $10 billion 0.87875% Fund net assets greater than $10 billion 0.85500% Page 27 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) Prior to November 1, 2022, EMLP and ECLN each paid First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. EIP receives a sub-advisory fee for EMLP from First Trust equal to 45% of any remaining monthly investment management fee paid to First Trust after the Fund's average Fund expenses accrued during the most recent twelve months are subtracted from the investment management fee in a given month. EIP receives a sub-advisory fee for ECLN and EIPX from First Trust equal to 50% of the monthly investment management fee paid to First Trust less one-half of the Fund's expenses, for which EIP is responsible. During any period in which the Advisor's management fee is reduced in accordance with the breakpoints described above, the investment sub-advisory fee (which is based on the Advisor's management fee) paid to EIP will be reduced to reflect the reduction in the Advisor's management fee. First Trust Capital Partners, LLC ("FTCP"), an affiliate of First Trust, owns, through a wholly-owned subsidiary, a 15% ownership interest in each of EIP and EIP Partners, LLC, an affiliate of EIP. 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 each Fund. As custodian, BNYM is responsible for custody of each Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of each Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for each Fund. BNYM is a subsidiary of The Bank of New York Mellon Corporation, a financial holding company. Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates ("Independent Trustees") is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a target outcome fund or an index fund. Additionally, the Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4. PURCHASES AND SALES OF SECURITIES For the period ended April 30, 2023, the cost of purchases and proceeds from sales of investments for each Fund, excluding short-term investments and in-kind transactions, were as follows: Purchases Sales --------------- --------------- First Trust North American Energy Infrastructure Fund $ 415,960,799 $ 506,836,738 First Trust EIP Carbon Impact ETF 11,455,504 9,073,649 FT Energy Income Partners Strategy ETF 11,704,821 12,300,875 For the period ended April 30, 2023, the cost of in-kind purchases and proceeds from in-kind sales for each Fund were as follows: Purchases Sales --------------- --------------- First Trust North American Energy Infrastructure Fund $ 32,670,118 $ 142,806,136 First Trust EIP Carbon Impact ETF 4,285,024 1,255,866 FT Energy Income Partners Strategy ETF 129,556,892 12,973,480 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES Each Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as "Authorized Participants" have contractual arrangements with a Fund or one of the Fund's service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as "Creation Units." Prior to the start of trading on every business day, a Fund publishes through the National Securities Clearing Corporation ("NSCC") the "basket" of securities, cash or other assets that it Page 28 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) will accept in exchange for a Creation Unit of the Fund's shares. An Authorized Participant that wishes to effectuate a creation of a Fund's shares deposits with the Fund the "basket" of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund's shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold a Fund's shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a Creation Unit of a Fund's shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in a Fund's shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of a Fund's shares at or close to the NAV per share of the Fund. Each Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket. Each Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by a Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed. 6. DISTRIBUTION PLAN The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are authorized to pay an amount up to 0.25% of their average daily net assets each year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services. No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before March 31, 2024 for EMLP and ECLN and October 28, 2024 for EIPX. 7. INDEMNIFICATION The Trust, on behalf of the Funds, has a variety of indemnification obligations under contracts with its service providers. The Trust's maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 8. SUBSEQUENT EVENTS Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were issued and has determined that there was the following subsequent event: On May 23, 2023, the Advisor's Pricing Committee approved changes to the Advisor's Valuation Procedures for the First Trust Funds, including clarifications to certain pricing methodologies. These changes will be reflected in future reports' Notes to Financial Statements. Page 29 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that the Trust uses to determine how to vote proxies and information on how each Fund voted proxies relating to its portfolio securities during the most recent 12-month period ended June 30 is available (1) without charge, upon request, by calling (800) 988-5891; (2) on each Fund's website at www.ftportfolios.com; and (3) on the Securities and Exchange Commission's ("SEC") website at www.sec.gov. PORTFOLIO HOLDINGS Each Fund files portfolio holdings information for each month in a fiscal quarter within 60 days after the end of the relevant fiscal quarter on Form N-PORT. Portfolio holdings information for the third month of each fiscal quarter will be publicly available on the SEC's website at www.sec.gov. Each Fund's complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the semi-annual and annual reports to shareholders, respectively, and is filed with the SEC on Form N-CSR. The semi-annual and annual report for each Fund is available to investors within 60 days after the period to which it relates. Each Fund's Forms N-PORT and Forms N-CSR are available on the SEC's website listed above. RISK CONSIDERATIONS RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE, RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND. CONCENTRATION RISK. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund's investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund's corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified. CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer's ability to make such payments. CYBER SECURITY RISK. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund's third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches. DEFINED OUTCOME FUNDS RISK. To the extent a fund's investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor's investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund's share price will 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. Page 30 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) DERIVATIVES RISK. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivative. These risks are heightened when a fund's portfolio managers use derivatives to enhance the fund's return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund. EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the value of the fund's shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. ETF RISK. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF's shares, or decisions by an ETF's authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF's shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads. FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund's fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund's fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities. INDEX OR MODEL CONSTITUENT RISK. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund's net asset value could be negatively impacted and the fund's market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund's shares. INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund's costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders. INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund's investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests. 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. Page 31 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate ("SOFR") will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund. MANAGEMENT RISK. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund's investment portfolio, the fund's portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective. MARKET RISK. Market risk is the risk that a particular security, or shares of a fund in general, may fall in value. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The COVID-19 global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets. While the U.S. has resumed "reasonably" normal business activity, many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. These events also adversely affect the prices and liquidity of a fund's portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a fund's shares and result in increased market volatility. During any such events, a fund's shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on a fund's shares may widen. NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries. OPERATIONAL RISK. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect a fund's ability to meet its investment objective. Although the funds and the funds' investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets. PREFERRED SECURITIES RISK. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company's capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock. Page 32 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) 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 LIQUIDITY RISK MANAGEMENT PROGRAM In accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (the "1940 Act"), the Funds and each other fund in the First Trust Fund Complex, other than the closed-end funds, have adopted and implemented a liquidity risk management program (the "Program") reasonably designed to assess and manage the funds' liquidity risk, i.e., the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors' interests in the fund. The Board of Trustees of the First Trust Funds has appointed First Trust Advisors L.P. (the "Advisor") as the person designated to administer the Program, and in this capacity the Advisor performs its duties primarily through the activities and efforts of the First Trust Liquidity Committee (the "Liquidity Committee"). Pursuant to the Program, the Liquidity Committee classifies the liquidity of each fund's portfolio investments into one of the four liquidity categories specified by Rule 22e-4: highly liquid investments, moderately liquid investments, less liquid investments and illiquid investments. The Liquidity Committee determines certain of the inputs for this classification process, including reasonably anticipated trade sizes and significant investor dilution thresholds. The Liquidity Committee also determines and periodically reviews a highly liquid investment minimum for certain funds, monitors the funds' holdings of assets classified as illiquid investments to seek to ensure they do not exceed 15% of a fund's net assets and establishes policies and procedures regarding redemptions in kind. At the April 17, 2023 meeting of the Board of Trustees, as required by Rule 22e-4 and the Program, the Advisor provided the Board with a written report prepared by the Advisor that addressed the operation of the Program during the period from March 17, 2022 through the Liquidity Committee's annual meeting held on March 23, 2023 and assessed the Program's adequacy and effectiveness of implementation during this period, including the operation of the highly liquid investment minimum for each fund that is required under the Program to have one, and any material changes to the Program. Note that because the Funds primarily hold assets that are highly liquid investments, the Funds have not adopted any highly liquid investment minimums. As stated in the written report, during the review period, two funds breached the 15% limitation on illiquid investments for one day each, as a result of an unscheduled week-long closure of the stock exchange in Istanbul following devastating earthquakes in February, causing all Turkish equities to be re-classified as "illiquid" for one day. Each fund filed a Form N-RN on the day after the breach occurred, and one day later after the breach was cured. No fund with a highly liquid investment minimum breached that minimum during the reporting period. The Advisor concluded that each fund's investment strategy is appropriate for an open-end fund; that the Program operated effectively in all material respects during the review period; and that the Program is reasonably designed to assess and manage the liquidity risk of each fund and to maintain compliance with Rule 22e-4. ADVISORY AND SUB-ADVISORY AGREEMENTS BOARD CONSIDERATIONS REGARDING APPROVAL OF INVESTMENT MANAGEMENT AND SUB-ADVISORY AGREEMENTS The Board of Trustees of First Trust Exchange-Traded Fund IV (the "Trust"), including the Independent Trustees, approved the Investment Management Agreement (the "Advisory Agreement") with First Trust Advisors L.P. (the "Advisor"), on behalf of FT Energy Income Partners Strategy ETF (the "Fund"), and the Investment Sub-Advisory Agreement (the "Sub-Advisory Agreement" and together with the Advisory Agreement, the "Agreements") among the Trust, on behalf of the Fund, the Advisor and Energy Income Partners, LLC (the "Sub-Advisor"), for an initial two-year term at a meeting held on September 19, 2022. The Board determined that the Agreements are in the best interests of the Fund in light of the nature, extent and quality of the services expected to be provided and such other matters as the Board considered to be relevant in the exercise of its business judgment. Page 33 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) 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. To assist the Board in its evaluation of the Agreements for the Fund, the Independent Trustees received a separate report from each of the Advisor and the Sub-Advisor in advance of the Board meeting 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 to be provided by the Advisor and the Sub-Advisor to the Fund (including the relevant personnel responsible for these services and their experience); the proposed 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 exchange-traded funds ("ETFs") managed by the Advisor; the proposed sub-advisory fee rate as compared to fees charged to other clients of the Sub-Advisor; the estimated expense ratio of the Fund as compared to expense ratios of the funds in the Fund's Expense Group and Expense Universe; the nature of expenses to be incurred in providing services to the Fund and the potential for the Advisor and the Sub-Advisor to realize economies of scale, if any; profitability and other financial data for the Advisor; financial data for the Sub-Advisor; any indirect benefits to the Advisor and its affiliates, First Trust Portfolios L.P. ("FTP") and First Trust Capital Partners, LLC ("FTCP"), and the Sub-Advisor; and information on the Advisor's and the Sub-Advisor's compliance programs. The Independent Trustees and their counsel also met separately to discuss the information provided by the Advisor and the Sub-Advisor. The Board applied its business judgment to determine whether the arrangements between the Trust and the Advisor and among the Trust, the Advisor and the Sub-Advisor are reasonable business arrangements from the Fund's perspective. In evaluating whether to approve the Agreements for the Fund, the Board considered the nature, extent and quality of the services to be provided by the Advisor and the Sub-Advisor under the Agreements. With respect to the Advisory Agreement, the Board considered that the Advisor will be responsible for the overall management and administration of the Fund and reviewed all of the services to be provided by the Advisor to the Fund, including the oversight of the Sub-Advisor, as well as the background and experience of the persons who will be responsible for such services. The Board considered that the Fund will be an actively-managed ETF and will employ an advisor/sub-advisor management structure and considered that the Advisor manages other ETFs with a similar structure in the First Trust Fund Complex. The Board noted that the Advisor will oversee the Sub-Advisor's day-to-day management of the Fund's investments, including portfolio risk monitoring and performance review. In reviewing the services to be provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor's, the Sub-Advisor's and the Fund's compliance with the 1940 Act, as well as the Fund's compliance with its investment objective, policies and restrictions. The Board noted that employees of the Advisor provide management services to other ETFs and to other funds in the First Trust Fund Complex with diligence and care. With respect to the Sub-Advisory Agreement, in addition to the written materials provided by the Sub-Advisor, at the September 19, 2022 meeting, the Board also received a presentation from representatives of the Sub-Advisor, who discussed the services that the Sub-Advisor will provide to the Fund, and the Trustees were able to ask questions about the proposed investment strategy for the Fund. The Board noted the background and experience of the Sub-Advisor's portfolio management team and the Sub-Advisor's investment style. Because the Fund had yet to commence investment operations, the Board could not consider the historical investment performance of the Fund. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of the services to be provided to the Fund by the Advisor and the Sub-Advisor under the Agreements are expected to be satisfactory. The Board considered the proposed unitary fee rate payable by the Fund under the Advisory Agreement for the services to be provided. The Board noted that, under the unitary fee arrangement, the Fund would pay the Advisor a unitary fee equal to an annual rate of 0.95% of its average daily net assets. The Board considered that, from the unitary fee for the Fund, the Advisor would pay the Sub-Advisor a sub-advisory fee equal to an annual rate of 0.475% of the Fund's average daily net assets less one-half of the Fund's expenses. The Board noted that the Advisor and the Sub-Advisor would be responsible for the Fund's expenses, including the cost of sub-advisory, transfer agency, custody, fund administration, legal, audit and other services and license fees, if any, but excluding the fee payment under the Advisory Agreement and interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses, if any. The Board received and reviewed information showing the fee rates and expense ratios of the peer funds in the Expense Group, as well as advisory and unitary fee rates charged by the Advisor and Sub-Advisor to other fund (including ETF) and non-fund clients, as applicable. Because the Fund will pay a unitary fee, the Board determined that expense ratios were the most relevant comparative data point. Based on the information provided, the Board Page 34 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) 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 discussed with representatives of the Advisor how the Expense Group was assembled and how the Fund compared and differed from the peer funds. The Board took this information into account in considering the peer data. With respect to fees charged to other clients, the Board considered the Advisor's statement that the Fund will be most comparable to another actively-managed ETF in the First Trust Fund Complex that is sub-advised by the Sub-Advisor, which pays a unitary fee equal to an annual rate of 0.95% of its average daily net assets. In light of the information considered and the nature, extent and quality of the services expected to be provided to the Fund under the Agreements, the Board determined that the proposed unitary fee, including the sub-advisory fee to be paid by the Advisor to the Sub-Advisor from the unitary fee, was fair and reasonable. The Board noted that the proposed unitary fee for the Fund was not structured to pass on to shareholders the benefits of any economies of scale as the Fund's assets grow. The Board noted that any reduction in fixed costs associated with the management of the Fund would benefit the Advisor and the Sub-Advisor, but that the unitary fee structure provides a level of certainty in expenses for the Fund. The Board noted that the Advisor has continued to build infrastructure and add new staff to improve the services to the funds in the First Trust Fund Complex. The Board took into consideration the types of costs to be borne by the Advisor in connection with its services to be performed for the Fund under the Advisory Agreement. The Board considered the Advisor's estimate of the asset level for the Fund at which the Advisor expects the Advisory Agreement to be profitable to the Advisor and the Advisor's estimate of the profitability of the Advisory Agreement if the Fund's assets reach $100 million. The Board noted the inherent limitations in the profitability analysis and concluded that, based on the information provided, the Advisor's estimated profitability level for the Fund was not unreasonable. The Board reviewed financial information provided by the Sub-Advisor, but did not review any potential profitability of the Sub-Advisory Agreement to the Sub-Advisor. The Board considered that the Sub-Advisor would be paid by the Advisor from the Fund's unitary fee and its understanding that the sub-advisory fee rate was the product of an arm's length negotiation. In addition, the Board considered indirect benefits described by the Advisor that may be realized from its relationship with the Fund. The Board noted that FTCP has an ownership interest in the Sub-Advisor and considered potential indirect benefits to the Advisor from such ownership interest. The Board also considered that the Advisor had identified as an indirect benefit to the Advisor and FTP their exposure to investors and brokers who, absent their exposure to the Fund, may have had no dealings with the Advisor or FTP. The Board considered indirect benefits described by the Sub-Advisor that may be realized from its relationship with the Fund, including soft-dollar arrangements, and considered a summary of such arrangements. The Board also considered the potential indirect benefits to the Sub-Advisor from the ownership interest of FTCP in the Sub-Advisor. The Board concluded that the character and amount of potential indirect benefits to the Advisor and the Sub-Advisor were not unreasonable. Based on all of the information considered and the conclusions reached, the Board, including the Independent Trustees, determined that the terms of the Agreements are fair and reasonable and that the approval of the Agreements is in the best interests of the Fund. No single factor was determinative in the Board's analysis. BOARD CONSIDERATIONS REGARDING APPROVAL OF AMENDMENTS TO THE INVESTMENT MANAGEMENT AND SUB-ADVISORY AGREEMENTS The Board of Trustees of First Trust Exchange-Traded Fund IV (the "Trust"), including the Independent Trustees, unanimously approved the amendment (the "Advisory Agreement Amendment") of the Investment Management Agreement (the "Advisory Agreement") with First Trust Advisors L.P. (the "Advisor") and the amendment (the "Sub-Advisory Agreement Amendment" and together with the Advisory Agreement Amendment, the "Amendments") of the Investment Sub-Advisory Agreement (the "Sub-Advisory Agreement" and together with the Advisory Agreement, the "Agreements") among the Trust, the Advisor and Energy Income Partners, LLC (the "Sub-Advisor") on behalf of the FT Energy Income Partners Strategy ETF (the "Fund"). The Board approved the Amendments 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 Amendments at a meeting held on September 18-19, 2022. Following those preliminary discussions, the Board requested and received information from the Advisor regarding the proposed Amendments, 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 Advisory Agreement Amendment, the Board considered that the purpose of the Advisory Agreement Amendment is to modify the unitary fee rate for the Fund under the Advisory 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. In reviewing the Sub-Advisory Agreement Amendment, the Board considered that the purpose of the Sub-Advisory Agreement Amendment is to modify the sub-advisory fee rate for the Fund under the Sub-Advisory Agreement to reflect the modification of the unitary fee rate schedule under the Advisory Agreement Amendment. The Board noted the Advisor's representations that the quality and quantity of the services Page 35 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED FUND IV APRIL 30, 2023 (UNAUDITED) provided to the Fund by the Advisor under the Advisory Agreement and by the Sub-Advisor under the Sub-Advisory Agreement will not be reduced or modified as a result of the Advisory Agreement Amendment and the Sub-Advisory Agreement Amendment, and that the obligations of the Advisor under the Advisory Agreement and the obligations of the Sub-Advisor under the Sub-Advisory Agreement will remain the same in all respects. The Board noted that it, including the Independent Trustees, approved the Agreements for an initial two-year period ending October 28, 2024 at a meeting held on September 19, 2022. The Board noted that in connection with such approval it had determined, based upon the information provided, that the terms of the Agreements were fair and reasonable and that the approval of the Agreements was in the best interests of the Fund in light of the nature, extent and quality of the services expected to be 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 Amendments are fair and reasonable and that the Amendments are in the best interests of the Fund.
