Performance and Risk Disclosure

There is no assurance that the Fund will achieve its investment objective. The Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund’s shares may therefore be less than what you paid for them. Accordingly, you can lose money by investing in the Fund. See “Risk Considerations” in the Additional Information section of this report for a discussion of certain other risks of investing in the Fund.

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

The Advisor may also periodically provide additional information on Fund performance on the Fund’s web page at www.ftportfolios.com.

Shareholder Letter

First Trust Preferred Securities and Income ETF (FPE)

Semi-Annual Letter from the Chairman and CEO

April 30, 2021

Dear Shareholders,

First Trust is pleased to provide you with the semi-annual report for the First Trust Preferred Securities and Income ETF (the “Fund”), which contains detailed information about the Fund for the six months ended April 30, 2021.

I would like to begin my remarks by saying that this is a time for all of us to be thankful. It is astounding to me that our scientists and extended health care community successfully discovered, developed, and distributed multiple effective vaccines to treat the coronavirus (“COVID-19”) in the span of just 15 months. Suffice it to say that we are witnessing history in the making. We even received some good news recently with respect to wearing masks in public, a polarizing act for many politicians and Americans. The Centers for Disease Control and Prevention released a new set of guidelines in mid-May for those individuals who have been fully vaccinated. It essentially says fully vaccinated Americans can quit wearing their masks outdoors (even in crowds), in most indoor settings, and can drop social distancing altogether. This is a big step towards expediting the reopening of the U.S. economy.

For those who may not know, we subscribe to the buy-and-hold philosophy of investing here at First Trust Advisors L.P., even though it means enduring lots of tough times. While the notion of being able to time the market is seductive on its face, very few investors are skilled enough to make it work over time. I can think of no better example than the COVID-19 pandemic. The degree of uncertainty surrounding the onset of the virus alone was enough to make the average investor want to run for cover. And if that was not enough, the 33.8% plunge in the S&P 500^® Index (the “Index”) from February 19, 2020, through March 23, 2020 (23 trading days) was a real gut check for most of us. But a funny thing happened on the way to another potential collapse of the market − it did not happen. In fact, thanks to the U.S. Federal government stepping up with trillions of dollars of timely fiscal and monetary support, the stock market roared. From March 23, 2020 through May 14, 2021, the Index posted a total return of 90.14%, according to Bloomberg. What a shame for those investors who may have moved some, or all, of their capital out of equities. What looked like a great time to de-risk turned out to be just the opposite.

The overall climate for investing looks bright for a few reasons. First, U.S. real gross domestic product (“GDP”) growth is expected to grow by 6.4% year-over-year in 2021, according to the International Monetary Fund. The last time the U.S. economy grew that fast was in 1984, when real GDP growth reached 7.2%. Second, corporate earnings are expected to recover from their 2020 slide. Bloomberg’s consensus year-over-year earnings growth rate estimates for the Index for 2021 and 2022 were 33.17% and 12.87%, respectively, as of May 14, 2021. That is a significant rebound from the 12.44% decline in earnings in 2020. Third, inflation is rising, and that is exactly what the Federal Reserve has been wanting for some time. Central banks around the world have spent years battling deflationary pressures, so a little bit of inflation is welcome at this stage of the recovery. Lastly, the U.S. labor market is robust despite the talk about the millions of people who lost their jobs in the COVID-19 pandemic and are living off unemployment benefits. As of March 31, 2021, there were 8.12 million job openings in the U.S., the highest total since record-keeping began in December 2000, according to the Bureau of Labor Statistics. We need to get people back to work.

While it seems fashionable to sell fear these days, we choose to follow the data. Remember, the Index has never failed to fully recoup the losses sustained in a market correction or bear market. Stay the course!

Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Fund again in six months.

Sincerely,

James A. Bowen

Chairman of the Board of Trustees

Chief Executive Officer of First Trust Advisors L.P.

Fund Performance Overview (Unaudited)

First Trust Preferred Securities and Income ETF (FPE)

First Trust Preferred Securities and Income ETF’s (the “Fund”) investment objective is to seek total return and to provide current income. Under normal market conditions, the Fund invests at least 80% of its net assets (including investment borrowings) in preferred securities (“Preferred Securities”) and income-producing debt securities (“Income Securities”). The Fund invests in securities that are traded over-the-counter or listed on an exchange. For purposes of the 80% test set forth above, securities of open-end funds, closed-end funds or other exchange-traded funds (“ETFs”) registered under the Investment Company Act of 1940, as amended, that invest primarily in Preferred Securities or Income Securities are deemed to be Preferred Securities or Income Securities.

Preferred Securities held by the Fund generally pay fixed or adjustable-rate distributions to investors and have preference over common stock in the payment of distributions and the liquidation of a company’s assets, but are generally junior to all forms of the company’s debt, including both senior and subordinated debt. Certain of the Preferred Securities may be issued by trusts or other special purpose entities created by companies specifically for the purpose of issuing such securities. Income Securities that may be held by the Fund include corporate bonds, high yield securities (commonly referred to as “junk” bonds) and convertible securities. The broad category of corporate debt securities includes debt issued by U.S. and non-U.S. companies of all kinds, including those with small, mid and large capitalizations. Corporate debt may carry fixed or floating rates of interest.

Blended Index⁽¹⁾	4.09%	11.46%	6.40%	6.09%	36.34%	62.48%

Total returns for the period since inception are calculated from the inception date of the Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s per share net asset value (“NAV”) is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under 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 was calculated. Since shares of the Fund did not trade in the secondary market until after its inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in the Fund at NAV and Market Price, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future performance.

⁽¹⁾

The Blended Index consists of a 50/50 blend of the ICE BofA Fixed Rate Preferred Securities Index and the ICE BofA U.S. Capital Securities Index. The Blended Index reflects the diverse allocation of institutional preferred and hybrid securities in the Fund’s portfolio. The indexes do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the performance shown. Indexes are unmanaged and an investor cannot invest directly in an index. The Blended Index 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 Index for each period shown above.

Understanding Your Fund Expenses

April 30, 2021 (Unaudited)

As a shareholder of the First Trust Preferred Securities and Income ETF (the “Fund”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended April 30, 2021.

Actual Expenses

The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this six-month period.

Hypothetical Example for Comparison Purposes

The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value November 1, 2020	Ending Account Value April 30, 2021	Annualized Expense Ratio Based on the Six-Month Period	Expenses Paid During the Six-Month Period (a)
First Trust Preferred Securities and Income ETF (FPE)
Actual	$1,000.00	$1,079.90	0.85%	$4.38
Hypothetical (5% return before expenses)	$1,000.00	$1,020.58	0.85%	$4.26

(a)	Expenses are equal to the annualized expense ratios as indicated in the table multiplied by the average account value over the period (November 1, 2020 through April 30, 2021), multiplied by 181/365 (to reflect the six-month period).

First Trust Preferred Securities and Income ETF (FPE)

April 30, 2021 (Unaudited)

1. Organization

First Trust Exchange-Traded Fund III (the “Trust”) is a diversified open-end management investment company organized as a Massachusetts business trust on January 9, 2008, 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 seventeen funds that are offering shares. This report covers the First Trust Preferred Securities and Income ETF (the “Fund”), which trades under the ticker FPE on the NYSE Arca, Inc. 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. The investment objective of the Fund is to seek total return and to provide current income. Under normal market conditions, the Fund invests at least 80% of its net assets (including investment borrowings) in preferred securities and income-producing debt securities, including corporate bonds, high-yield securities (commonly referred to as “junk” bonds) and convertible securities. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.

2. Significant Accounting Policies

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

A. Portfolio Valuation

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

The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund’s investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures adopted by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act. 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:

Exchange-traded funds, preferred stocks, real estate investment trusts (“REITs”) 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 principal market for such securities.

Bonds, notes, capital preferred securities, and other debt securities are fair valued on the basis of valuations provided by dealers who make markets in such securities or by a third-party pricing service approved by the Trust’s Board of Trustees, 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.

April 30, 2021 (Unaudited)

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.

Securities traded in an over-the-counter market are fair 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 Trust’s Board of Trustees or its delegate, 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 (the “1933 Act”)) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:

1)	the type of security;
2)	the size of the holding;
3)	the initial cost of the security;
4)	transactions in comparable securities;
5)	price quotes from dealers and/or third-party pricing services;
6)	relationships among various securities;
7)	information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
8)	an analysis of the issuer’s financial statements; and
9)	the existence of merger proposals or tender offers that might affect the value of the security.

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; and
8)	whether the effects of the event are isolated or whether they affect entire markets, countries or regions.

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

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

o	Quoted prices for similar investments in active markets.
o	Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value the Fund’s investments as of April 30, 2021, is included with the Fund’s Portfolio of Investments.

B. Securities Transactions and Investment Income

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

Distributions received from the Fund’s investments in 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. The Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by the Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude.

The United Kingdom’s Financial Conduct Authority, which regulates the London Interbank Offered Rates (“LIBOR”), announced on March 5, 2021 that all non-USD LIBOR reference rates and the 1-week and 2-month USD LIBOR reference rates will cease to be provided or no longer be representative immediately after December 31, 2021 and the remaining USD LIBOR settings will cease to be provided or no longer be representative immediately after June 30, 2023. The International Swaps and Derivatives Association, Inc. (“ISDA”) confirmed that the March 5, 2021 announcement 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.

At this time, it is not possible to predict the full impact of the elimination of LIBOR and the establishment of an alternative reference rate on the Fund or its investments.

C. Restricted Securities

April 30, 2021 (Unaudited)

Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. The Fund does not have the right to demand that such securities be registered. These securities are valued according to the valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are not expressed as a discount to the carrying value of a comparable unrestricted security. There are no unrestricted securities with the same maturity dates and yields for these issuers.

Security	Acquisition Date	Principal Value/Shares	Current Price	Carrying Cost	Value	% of Net Assets
Dairy Farmers of America, Inc., 7.13%	09/15/16-03/24/21	$8,200,000	$100.50	$8,291,000	$8,241,000	0.13%

				$64,702,382	$68,419,746	1.06%

D. Dividends and Distributions 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 capital gains earned by the Fund, if any, are distributed at least annually.

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 by the Fund during the fiscal year ended October 31, 2020, was as follows:

Distributions paid from:
Ordinary income	$249,230,037
Capital gains	—
Return of capital	17,657,142

As of October 31, 2020, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$—
Accumulated capital and other gain (loss)	(176,840,881)
Net unrealized appreciation (depreciation)	65,251,672

E. Income Taxes

The Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the 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. Taxable years ended 2017, 2018, 2019, and 2020 remain open to federal and state audit. As of April 30, 2021, 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, 2020, for federal income tax purposes, the Fund had $176,840,881 of capital loss carryforward available to the extent provided by regulations, to offset future capital gains.

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 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 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.

Stonebridge Advisors LLC (“Stonebridge” or the “Sub-Advisor”), a majority-owned affiliate of First Trust, serves as the Fund’s sub-advisor and manages the Fund’s portfolio subject to First Trust’s supervision. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust will supervise Stonebridge and its management of the investment of the Fund’s assets and will pay Stonebridge for its services as the Fund’s sub-advisor. First Trust is responsible for the Fund’s expenses, including the cost of transfer agency, sub-advisory, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, 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 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.85% of its average daily net assets. Stonebridge receives a sub-advisory fee equal to 0.425% of the average daily net assets of the Fund less Stonebridge’s share of the Fund’s expenses. The Sub-Advisor’s fee is paid by the Advisor out of the Advisor’s management fee. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.

First Trust Capital Partners, LLC (“FTCP”), an affiliate of First Trust, owns a 51% ownership interest in Stonebridge.

The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Fund. As custodian, BBH is responsible for custody of the Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of the Fund’s securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for the Fund.

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 defined-outcome fund or an index fund.

Additionally, the Lead Independent Trustee and the Chairmen 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 Chairmen 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 six months ended April 30, 2021, the cost of purchases and proceeds from sales of investments, excluding short term investments and in-kind transactions, were $1,496,684,304 and $895,221,429, respectively.

For the six months ended April 30, 2021, the cost of in-kind purchases and proceeds from in-kind sales were $78,097,731 and $1,586,410, respectively.

5. Creations, Redemptions and Transaction Fees

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 Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by the Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.

6. Distribution Plan

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide 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 February 28, 2022.

7. Borrowings

First Trust Preferred Securities and Income ETF, along with First Trust Series Fund and First Trust Exchange-Traded Fund IV, has a $330 million Credit Agreement with The Bank of Nova Scotia (“Scotia”) as administrative agent for a group of lenders. Prior to March 3, 2021 the commitment amount was $410 million. Scotia charges a commitment fee of 0.25% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans, and an agency fee. First Trust allocates the commitment fee and agency fee amongst the funds that have access to the credit line. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings outstanding during the six months ended April 30, 2021.

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. Subsequent Events

Management has evaluated the impact of all subsequent events to the Fund through the date the financial statements were issued, and has determined that there were the following subsequent events:

On May 13, 2021, First Trust New York Municipal High Income ETF, an additional series of the Trust, began trading under the symbol “FMNY” on the NYSE Arca, Inc.

For the next reporting period, the Fund will use a new blended index that consists of a 30/30/30/10 blend of the ICE BofA Core Plus Fixed Rate Preferred Securities Index, the ICE BofA US Investment Grade Institutional Capital Securities Index, the ICE USD Contingent Capital Index and the ICE BofA US High Yield Institutional Capital Securities Index. The new blended index is intended to reflect the proportional market cap of each segment of the preferred and hybrid securities market.

The 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 large 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 not concentrated.

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.

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 Constituent Risk. Certain funds may be a constituent of one or more indices. 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 significantly 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.

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, will cease making LIBOR available as a reference rate over a phase-out period that will begin immediately after December 31, 2021. 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. 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. The outbreak of the respiratory disease designated as COVID-19 in December 2019 has caused significant volatility and declines in global financial markets, which have caused losses for investors. The COVID-19 pandemic may last for an extended period of time and will continue to impact the economy for the foreseeable future.

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; lack of liquidity;

currency exchange rates; excessive taxation; government seizure of assets; 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. Although the funds and the 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.

Liquidity Risk Management Program

In accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (the “1940 Act”), the Fund 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 26, 2021 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 20, 2020 through the Liquidity Committee’s annual meeting held on March 16, 2021 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 Fund primarily holds assets that are highly liquid investments, the Fund has not adopted a highly liquid investment minimum.

As stated in the written report, during the review period, no fund breached the 15% limitation on illiquid investments, no fund with a highly liquid investment minimum breached that minimum and no fund filed a Form N-LIQUID. 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.

This report contains certain forward-looking statements within the meaning of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. 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 its 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 the series of First Trust Exchange-Traded Fund III (the “Trust”) described in this report (First Trust Managed Municipal ETF; hereinafter referred to as the “Fund”) 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 its 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 the Fund will achieve its investment objectives. The Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund’s shares may therefore be less than what you paid for them. Accordingly, you can lose money by investing in the Fund. See “Risk Considerations” in the Additional Information section of this report for a discussion of certain other risks of investing in the Fund.

The Advisor may also periodically provide additional information on Fund performance on the Fund’s web page at www.ftportfolios.com.

How to Read This Report

The statistical information that follows may help you understand the Fund’s performance compared to that of a relevant market benchmark.

It is important to keep in mind that the opinions expressed by personnel of the Advisor are just that: informed opinions. They should not be considered to be promises or advice. The opinions, like the statistics, cover the period through the date on the cover of this report. The material risks of investing in the Fund are spelled out in the prospectus, the statement of additional information, and other Fund regulatory filings.

Fund Performance Overview (Unaudited)

First Trust Managed Municipal ETF (FMB)

The primary investment objective of First Trust Managed Municipal ETF (the “Fund”) is to generate current income that is exempt from regular federal income taxes and its secondary objective is long term capital appreciation. The Fund lists and principally trades its shares on The Nasdaq Stock Market, LLC under the ticker symbol “FMB.” Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (including investment borrowings) in municipal debt securities that pay interest that is exempt from regular federal income taxes.

Performance
			Average Annual Total Returns		Cumulative Total Returns
	6 Months Ended 4/30/21	1 Year Ended 4/30/21	5 Years Ended 4/30/21	Inception (5/13/14) to 4/30/21	5 Years Ended 4/30/21	Inception (5/13/14) to 4/30/21
Fund Performance
NAV	3.71%	10.67%	3.98%	4.56%	21.57%	36.43%
Market Price	3.76%	10.54%	3.96%	4.57%	21.41%	36.53%
Index Performance
Bloomberg Barclays Revenue 10 Year (8-12) Index	2.59%	7.81%	3.56%	4.04%	19.09%	31.79%

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.

Understanding Your Fund Expenses

April 30, 2021 (Unaudited)

As a shareholder of the First Trust Managed Municipal 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 April 30, 2021.

Actual Expenses

Hypothetical Example for Comparison Purposes

	Beginning Account Value November 1, 2020	Ending Account Value April 30, 2021	Annualized Expense Ratio Based on the Six-Month Period (a)	Expenses Paid During the Six-Month Period (b)
First Trust Managed Municipal ETF (FMB)
Actual	$1,000.00	$1,037.10	0.50%	$2.53
Hypothetical (5% return before expenses)	$1,000.00	$1,022.32	0.50%	$2.51

(a)	These expense ratios reflect expense waivers. See Note 3 in the Notes to Financial Statements.
(b)	Expenses are equal to the annualized expense ratios as indicated in the table multiplied by the average account value over the period (November 1, 2020 through April 30, 2021), multiplied by 181/365 (to reflect the six-month period).

First Trust Managed Municipal ETF (FMB)

April 30, 2021 (Unaudited)

1. Organization

First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Trust currently consists of seventeen funds that are offering shares. This report covers the First Trust Managed Municipal ETF (the “Fund”), a diversified series of the Trust, which trades under the ticker “FMB” on The Nasdaq Stock Market LLC. 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 primary investment objective of the Fund is to generate current income that is exempt from regular federal income taxes and its secondary objective is long term capital appreciation. Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (including investment borrowings) in municipal debt securities that pay interest that is exempt from regular federal income taxes. There can be no assurance that the Fund will achieve its investment objectives. The Fund may not be appropriate for all investors.

2. Significant Accounting Policies

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 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.

Municipal securities and other debt securities are fair valued on the basis of fair valuations provided by dealers who make markets in such securities or by a third-party pricing service approved by the Trust’s Board of Trustees, 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.

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 fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

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.

1)	the fundamental business data relating to the issuer;
2)	an evaluation of the forces which influence the market in which these securities are purchased and sold;
3)	the type, size and cost of the security;
4)	the financial statements of the issuer;
5)	the credit quality and cash flow of the issuer, based on the Advisor’s or external analysis;
6)	the information as to any transactions in or offers for the security;
7)	the price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies;
8)	the coupon payments;
9)	the quality, value and salability of collateral, if any, securing the security; and
10)	other relevant factors.

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

o	Quoted prices for similar investments in active markets.
o	Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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

B. Securities Transactions and Investment Income

C. Restricted Securities

The Fund invests in restricted securities, which are securities that may not be offered for public sale without first being registered under the 1933 Act. Prior to registration, restricted securities may only be resold in transactions exempt from registration under Rule 144A under the 1933 Act, normally to qualified institutional buyers. As of April 30, 2021, the Fund held restricted securities as shown in the following table that the Advisor has deemed illiquid pursuant to procedures adopted by the Trust’s Board of Trustees. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. The Fund does not have the right to demand that such securities be registered. These securities are valued according to the valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are not expressed as a discount to the carrying value of a comparable unrestricted security. There are no unrestricted securities with the same maturity dates and yields for these issuers.

				$3,546,216	$3,829,174	0.17%

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 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. This daily fluctuation in the value of the contracts is also known as variation margin and is included in “Variation margin” payable or receivable 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.

Restricted cash segregated as collateral for futures contracts in the amount of $1,757,910 is shown as “Cash segregated as collateral for open futures contracts” on the Statement of Assets and Liabilities.

E. Dividends and Distributions to Shareholders

The tax character of distributions paid by the Fund during the fiscal year ended October 31, 2020, was as follows:

Distributions paid from:
Ordinary income	$9,278
Capital gains	—
Tax-exempt income	32,242,939
Return of capital	917,161

As of October 31, 2020, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$—
Accumulated capital and other gain (loss)	(21,941,526)
Net unrealized appreciation (depreciation)	58,224,308

F. 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 (the “Code”), 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.

In addition, the Fund intends to invest in such municipal securities to allow it to pay shareholders “exempt dividends” as defined in the Code.

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, 2020, for federal income tax purposes, the Fund had $21,941,526 of capital loss carryforwards available to the extent provided by regulations to offset future capital gains.

Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended October 31, 2020, the Fund had no net ordinary losses.

G. Expenses

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

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

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

Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust manages the investment of the Fund’s assets and is responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit 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 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. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.

The Trust’s Board of Trustees and the Advisor have entered into a Fee Waiver Agreement for the Fund pursuant to which the Advisor contractually agreed to waive management fees of 0.15% of average daily net assets until March 1, 2022. The waiver agreement may be terminated by action of the Trust’s Board of Trustees at any time upon 60 days’ written notice by the Trust on behalf of the Fund or by the Fund’s investment advisor only after March 1, 2022. First Trust does not have the right to recover the fees waived. During the six months ended April 30, 2021, the Advisor waived fees of $1,415,771.

4. Purchases and Sales of Securities

For the six months ended April 30, 2021, the cost of purchases and proceeds from sales of investments, excluding short term investments and in-kind transactions, were $454,632,228 and $75,941,607, respectively.

For the six months ended April 30, 2021, the Fund had no in-kind transactions.

Net realized gain (loss) on futures contracts	$4,622,016
Net change in unrealized appreciation (depreciation) on futures contracts	(383,125)

During the six months ended April 30, 2021, the notional value of futures contracts opened and closed were $513,002,422 and $484,653,516, respectively.

The Fund does not have the right to offset financial assets and liabilities related to futures 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.

7. Distribution Plan

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 February 28, 2022.

8. Borrowings

The Trust, on behalf of the Fund, along with First Trust Series Fund and First Trust Exchange-Traded Fund IV has a $330 million Credit Agreement with The Bank of Nova Scotia (“Scotia”) as administrative agent for a group of lenders. Prior to March 3, 2021, the commitment amount was $410 million. Scotia charges a commitment fee of 0.25% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans and an agency fee. First Trust allocates the commitment fee and agency fee amongst the funds that have access to the credit line. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings outstanding during the six months ended April 30, 2021.

Fund Performance Overview (Unaudited)

First Trust Long/Short Equity ETF (FTLS)

The investment objective of First Trust Long/Short Equity ETF (the “Fund”) is to seek to provide investors with long-term total return. Under normal conditions, the Fund will expose at least 80% of its net assets (including investment borrowings) to U.S. exchange-listed equity securities and/or U.S. exchange-traded funds (“ETFs”) that provide exposure to U.S. exchange-listed equity securities. The Fund pursues its investment objective by establishing long and short positions in a portfolio of U.S. exchange-listed equity securities and ETFs. The Fund’s portfolio may include U.S. exchange-listed equity securities of non-U.S. issuers, including the securities of non-U.S. issuers traded on U.S. exchanges in the form of depositary receipts.

The Fund’s portfolio is composed of both long and short positions in equity securities and ETFs. As opposed to taking long positions in which an investor seeks to profit from increases in the price of a security, short selling is a technique that will be used by the Fund to try and profit from the falling price of a security. Short selling involves selling a security that has been borrowed from a third party with the intention of buying an identical security back at a later date to return to that third party.

Having both long and short positions in an equity security portfolio is a common way to create returns that are independent of market moves. One advantage of a long and short portfolio is that the long and short positions may offset one another in a manner that results in a lower net exposure to the direction of the market. In addition, cash balances arising from the use of short selling typically will be held in money market instruments.

Fund Performance Overview (Unaudited) (Continued)

First Trust Long/Short Equity ETF (FTLS)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. 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. The Fund’s past performance does not predict future performance.

Understanding Your Fund Expenses

April 30, 2021 (Unaudited)

As a shareholder of the First Trust Long/Short Equity 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 April 30, 2021.

Actual Expenses

Hypothetical Example for Comparison Purposes

	Beginning Account Value November 1, 2020	Ending Account Value April 30, 2021	Annualized Expense Ratio Based on the Six-Month Period (a)	Expenses Paid During the Six-Month Period (a)(b)
First Trust Long/Short Equity ETF (FTLS)
Actual	$1,000.00	$1,121.90	1.42%	$7.47
Hypothetical (5% return before expenses)	$1,000.00	$1,017.75	1.42%	$7.10

(a)	Annualized expense ratio and expenses paid during the six-month period do not include fees and expenses of the underlying funds in which the Fund invests.
(b)	Expenses are equal to the annualized expense ratios as indicated in the table multiplied by the average account value over the period (November 1, 2020 through April 30, 2021), multiplied by 181/365 (to reflect the six-month period).

Notes to Financial Statements

First Trust Long/Short Equity ETF (FTLS)

April 30, 2021 (Unaudited)

1. Organization

First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, 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 seventeen funds that are offering shares. This report covers the First Trust Long/Short Equity ETF (the “Fund”), a diversified series of the Trust, which trades under the ticker “FTLS” on the NYSE Arca, Inc. 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 investment objective of the Fund is to seek to provide investors with long-term total return. Under normal conditions, the Fund will expose at least 80% of its net assets (including investment borrowings) to U.S. exchange-listed equity securities and/or U.S. exchange-traded funds (“ETFs”) that provide exposure to U.S. exchange-traded equity securities. The Fund pursues its investment objective by establishing long and short positions in a portfolio of U.S. exchange-listed equity securities and ETFs. The Fund’s portfolio may include U.S. exchange-listed equity securities of non-U.S. issuers, including the securities of non-U.S. issuers traded on U.S. exchanges in the form of depositary receipts. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.

2. Significant Accounting Policies

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. 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.

Common stocks, master limited partnerships (“MLPs”), real estate investment trusts (“REITs”) 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 principal market for such securities.

Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

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 type of security;
2)	the size of the holding;
3)	the initial cost of the security;
4)	transactions in comparable securities;
5)	price quotes from dealers and/or third-party pricing services;
6)	relationships among various securities;
7)	information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
8)	an analysis of the issuer’s financial statements; and
9)	the existence of merger proposals or tender offers that might affect the value of the security.

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

o	Quoted prices for similar investments in active markets.
o	Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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

B. Securities Transactions and Investment Income

Distributions received from the Fund’s investments in MLPs generally are comprised of return of capital and investment income. The 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.

C. Futures Contracts

The Fund may purchase or sell (i.e., is long or short) exchange-listed futures contracts to gain long or short exposure to broad based equity indexes. 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

Page 20

Table of Contents

Notes to Financial Statements (Continued)

First Trust Long/Short Equity ETF (FTLS)

April 30, 2021 (Unaudited)

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 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.

The Fund had no futures contracts at April 30, 2021.

D. Short Sales

Short sales are utilized for investment and risk management purposes and are transactions in which securities or other instruments (such as options, forwards, futures or other derivative contracts) are sold by the Fund, but 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 will pay 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 affected 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 that 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.

The Fund has established an account with Pershing, LLC for the purpose of borrowing securities that the Fund intends to sell short. The Fund is charged interest on debit margin balances at a rate equal to the Overnight Bank Funding Rate plus 40 basis points. With regard to securities held short, the Fund is credited a rebate equal to the market value of its short positions at a rate equal to the Overnight Bank Funding Rate less 25 basis points. This rebate rate applies to easy to borrow securities. Securities that are hard to borrow may earn a rebate that is less than the foregoing or may be subject to a premium charge on a security by security basis. The different rebate rate is determined at the time of a short sale request. For the six months ended April 30, 2021, the Fund had margin interest expense of $137,754, as shown on the Statement of Operations. Restricted cash in the amount of $97,052,642, as shown on the Statement of Assets and Liabilities, is associated with collateral at the broker as of April 30, 2021.

E. Dividends and Distributions to Shareholders

Dividends from net investment income, if any, are declared and paid quarterly by the Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by the Fund, if any, are distributed at least annually.

The tax character of distributions paid by the Fund during the fiscal year ended October 31, 2020, was as follows:

Page 21

Table of Contents

Notes to Financial Statements (Continued)

First Trust Long/Short Equity ETF (FTLS)

April 30, 2021 (Unaudited)

Distributions paid from:
Ordinary income	$722,995
Capital gains	—
Return of capital	—

As of October 31, 2020, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$614,766
Accumulated capital and other gain (loss)	(42,038,756)
Net unrealized appreciation (depreciation)	11,765,813

F. Income Taxes

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, 2020, for federal income tax purposes, the Fund had $42,038,756 of non-expiring capital loss carryforwards available to the extent provided by regulations to offset future capital gains.

G. Expenses

Expenses, other than the investment advisory fee, dividend and interest expenses on investments sold short and other excluded expenses, are paid by the Advisor (See Note 3).

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

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

Pursuant to the Investment Management Agreement, 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, 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, acquired fund fees and expenses, dividend expenses on investments sold short, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. In addition, the Fund incurs acquired fund fees and expenses. The total of the unitary management fee and acquired fund fees and expenses represents the Fund’s total annual operating expenses. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.

Fund Performance Overview (Unaudited) (Continued)

First Trust Emerging Markets Local Currency Bond ETF (FEMB)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. 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. The Fund’s past performance does not predict future performance.

Understanding Your Fund Expenses

April 30, 2021 (Unaudited)

As a shareholder of the First Trust Emerging Markets Local Currency Bond 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 April 30, 2021.

Actual Expenses

Hypothetical Example for Comparison Purposes

	Beginning Account Value November 1, 2020	Ending Account Value April 30, 2021	Annualized Expense Ratio Based on the Six-Month Period	Expenses Paid During the Six-Month Period (a)

First Trust Emerging Markets Local Currency Bond ETF (FEMB)

April 30, 2021 (Unaudited)

1. Organization

First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, 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 seventeen funds that are offering shares. This report covers the First Trust Emerging Markets Local Currency Bond ETF (the “Fund”), a non-diversified series of the Trust, which trades under the ticker “FEMB” on The Nasdaq Stock Market LLC (“Nasdaq”). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large specified blocks of shares called “Creation Units.”

The Fund is an actively managed exchange-traded fund. The investment objective of the Fund is to seek maximum total return and current income. Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in bonds, notes and bills issued or guaranteed by entities incorporated or domiciled in emerging market countries that are denominated in the local currency of the issuer. There can be no assurance the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.

2. Significant Accounting Policies

The Fund is considered an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) 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

Corporate bonds, notes and other debt securities are fair valued on the basis of valuations provided by dealers who make markets in such securities or by a third-party pricing service approved by the Fund’s Board of Trustees, 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.

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.

Forward foreign currency contracts are fair valued at the current day’s interpolated foreign exchange rate, as calculated using the current day’s spot rate, and the thirty, sixty, ninety, and one-hundred eighty day forward rates provided by a third-party pricing service.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Trust’s Board of Trustees or its delegate, the Advisor’s Pricing Committee, at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:

1)	the fundamental business data relating to the issuer, or economic data relating to the country of issue;
2)	an evaluation of the forces which influence the market in which these securities are purchased and sold;
3)	the type, size and cost of the security;
4)	the financial statements of the issuer, or the financial condition of the country of issue;
5)	the credit quality and cash flow of the issuer, or country of issue, based on the Advisor’s or external analysis;
6)	the information as to any transactions in or offers for the security;
7)	the price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies;
8)	the coupon payments;
9)	the quality, value and salability of collateral, if any, securing the security;
10)	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);
11)	the economic, political and social prospects/developments of the country of issue and the assessment of the country’s governmental leaders/officials (for sovereign 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.

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

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

o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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

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. Amortization of premiums and accretion of discounts are recorded using the effective interest method.

C. Forward Foreign Currency Contracts

The Fund is subject to foreign currency risk in the normal course of pursuing its investment objective. Forward foreign currency contracts are agreements between two parties (“Counterparties”) to exchange one currency for another at a future date and at a specified price. The Fund uses forward foreign currency contracts to facilitate transactions in foreign securities and to manage the Fund’s foreign currency exposure. These contracts are valued daily, and the Fund’s net equity therein, representing unrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in “Unrealized appreciation on forward foreign currency contracts” and “Unrealized depreciation on forward foreign currency contracts” on the Statement of Assets and Liabilities. The change in unrealized appreciation (depreciation) is included in “Net change in unrealized appreciation (depreciation) on forward foreign currency contracts” on the Statement of Operations. When the forward contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or the cost of) the closing transaction and the Fund’s basis in the contract. This realized gain or loss is included in “Net realized gain (loss) on forward foreign currency contracts” on the Statement of Operations. Risks arise from the possible inability of Counterparties to meet the terms of their contracts and from movement in currency, securities values and interest rates. Due to the risks, the Fund could incur losses in excess of the net unrealized value shown on the Forward Foreign Currency Contracts table in the Portfolio of Investments. In the event of default by the Counterparty, the Fund will provide notice to the Counterparty of the Fund’s intent to convert the currency held by the Fund into the currency that the Counterparty agreed to exchange with the Fund. If a Counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Fund may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Fund may obtain only limited recovery or may obtain no recovery in such circumstances.

D. Foreign Currency

The books and records of the Fund 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 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 Statement 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 included in “Net change in unrealized appreciation (depreciation) on investments” on the Statement 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 are included in “Net realized gain (loss) on foreign currency transactions” on the Statement 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 Statement of Operations.

E. Offsetting on the Statement of Assets and Liabilities

Offsetting assets and liabilities requires entities to disclose both gross and net information about instruments and transactions eligible for offset on the Statement of Assets and Liabilities, and disclose instruments and transactions subject to master netting or similar agreements. These disclosure requirements are intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on the Fund’s financial position. The transactions subject to offsetting disclosures are derivative instruments, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions.

Notes to Financial Statements (Continued)

First Trust Emerging Markets Local Currency Bond ETF (FEMB)

April 30, 2021 (Unaudited)

This disclosure, if applicable, is included within each Fund’s Portfolio of Investments under the heading “Offsetting Assets and Liabilities.” For financial reporting purposes, the Fund does not offset financial assets and financial liabilities that are subject to master netting arrangements (“MNAs”) or similar agreements on the Statement of Assets and Liabilities. MNAs provide the right, in the event of default (including bankruptcy and insolvency), for the non-defaulting counterparty to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral.

At April 30, 2021, derivative assets and liabilities (by type) on a gross basis are as follows:

				Gross Amounts not Offset in the Statement of Assets and Liabilities
	Gross Amounts of Recognized Assets	Gross Amounts Offset in the Statement of Assets and Liabilities	Net Amounts of Assets Presented in the Statement of Assets and Liabilities	Financial Instruments	Collateral Amounts Received	Net Amount
Forward Foreign Currency Contracts*	$ 616,663	$ —	$ 616,663	$ (356,440)	$ —	$ 260,223
				Gross Amounts not Offset in the Statement of Assets and Liabilities
	Gross Amounts of Recognized Liabilities	Gross Amounts Offset in the Statement of Assets and Liabilities	Net Amounts of Liabilities Presented in the Statement of Assets and Liabilities	Financial Instruments	Collateral Amounts Pledged	Net Amount
Forward Foreign Currency Contracts*	$ (887,091)	$ —	$ (887,091)	$ 356,440	$ —	$ (530,651)

* The respective Counterparties for each contract are disclosed in the Forward Foreign Currency Contracts table in the Portfolio of Investments.

F. Dividends and Distributions to Shareholders

The tax character of distributions paid by the Fund during the fiscal year ended October 31, 2020, was as follows:

Distributions paid from:
Ordinary income	$181,578
Capital gains	—
Return of capital	9,530,411

Page 19

Table of Contents

Notes to Financial Statements (Continued)

First Trust Emerging Markets Local Currency Bond ETF (FEMB)

April 30, 2021 (Unaudited)

As of October 31, 2020, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$—
Accumulated capital and other gain (loss)	(3,548,643)
Net unrealized appreciation (depreciation)	(17,011,714)

G. Income Taxes

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. Taxable years ended 2017, 2018, 2019, and 2020 remain open to federal and state audit. As of April 30, 2021, 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, 2020, for federal income tax purposes, the Fund had $3,548,643 of capital loss carryforward available to the extent provided by regulations to offset future capital gains.

H. Expenses

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

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

First Trust, the investment advisor to the Fund, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for supervising 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.

The Trust, on behalf of the Fund, and First Trust have retained First Trust Global Portfolios Limited (“FTGP” or the “Sub-Advisor”), an affiliate of First Trust, to serve as investment sub-advisor. In this capacity, FTGP is responsible for the selection and ongoing monitoring of the securities in the Fund’s investment portfolio. First Trust is paid an annual unitary management fee of 0.85% of the Fund’s average daily net assets. FTGP receives a sub-advisory fee equal to 40% of any remaining monthly unitary fee paid to the Advisor after the Fund’s average expenses accrued during the most recent twelve months are subtracted from the unitary fee for that month. First Trust is responsible for the expenses of the Fund including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, Rule 12b-1 distribution and service fees, if any, brokerage expenses, taxes, interest, acquired fund fees and expenses, and extraordinary expenses. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.

The price received for each Creation Unit will equal the daily NAV per share of the Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by the Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.

7. Distribution Plan

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 February 28, 2022.

The Trust, on behalf of the Fund, along with First Trust Series Fund and First Trust Exchange-Traded Fund IV have a $330 million Credit Agreement with The Bank of Nova Scotia (“Scotia”) as administrative agent for a group of lenders. Prior to March 3, 2021, the commitment amount was $410 million. Scotia charges a commitment fee of 0.25% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans and an agency fee. First Trust allocates the commitment fee and agency fee amongst the funds that have access to the credit line. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings outstanding during the six months ended April 30, 2021.

Caution Regarding Forward-Looking Statements

This report contains certain forward-looking statements within the meaning of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. 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 RiverFront Investment Group, LLC (“RiverFront” 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 III (the “Trust”) described in this report (each such series is referred to as a “Fund” and collectively, 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 by 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.

The Advisor may also periodically provide additional information on Fund performance on each Fund’s web page at www.ftportfolios.com.

How to Read This Report

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

The statistical information that follows may help you understand each Fund’s performance compared to that of a relevant market benchmark.

It is important to keep in mind that the opinions expressed by personnel of the Advisor and/or Sub-Advisor are just that: informed opinions. They should not be considered to be promises or advice. The opinions, like the statistics, cover the period through the date on the cover of this report. The material risks of investing in each Fund are spelled out in the prospectus, the statement of additional information, and other Fund regulatory filings.

Fund Performance Overview (Unaudited)

First Trust RiverFront Dynamic Asia Pacific ETF (RFAP)

The investment objective of First Trust RiverFront Dynamic Asia Pacific ETF (the “Fund”) is to provide capital appreciation. Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of equity securities of Asian Pacific companies, including through investments in common stock, depositary receipts, and common and preferred shares of real estate investment trusts (“REITs”), and forward foreign currency exchange contracts and currency spot transactions used to hedge the Fund’s exposure to the currencies in which the equity securities of such Asian Pacific companies are denominated (each, an “Asian Pacific currency” and, collectively, the “Asian Pacific currencies”). Asian Pacific companies are those companies (i) whose securities are traded principally on a stock exchange in an Asian Pacific country, (ii) that have a primary business office in an Asian Pacific country, or (iii) that have at least 50% of their assets in, or derive at least 50% of their revenues or profits from, an Asian Pacific country. Asian Pacific countries include the countries located in Asia and the Pacific Islands as well as Australia and New Zealand. The Fund generally focuses its Asian Pacific company investments in Australia, Hong Kong, Japan, New Zealand and/or Singapore. Shares of the Fund are listed on The Nasdaq Stock Market LLC under the ticker symbol “RFAP.”

The Fund utilizes a dynamic currency hedging strategy through the use of forward foreign currency exchange contracts and currency spot transactions to hedge up to 100% of the Fund’s currency exposure. As a result of this hedging strategy, the portion of the Fund’s portfolio securities which are subject to currency hedging transactions may vary widely, from 0% to 100% of the portfolio securities. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract, at a price set on the date of the contract. A forward foreign currency exchange contract may reduce the Fund’s exposure to changes in the value of the currency it will deliver and increase its exposure to changes in the value of the currency it will receive for the duration of the contract. The effect on the value of the Fund is similar to selling securities denominated in one currency and purchasing securities denominated in another currency. The Fund also may enter into currency spot transactions as part of its dynamic currency hedging strategy. A currency spot transaction is an agreement between two parties to buy or sell a specific currency for delivery on a date that is typically two business days from the date of the agreement, as opposed to a date set in the future. The underlying currencies of the forward foreign currency exchange contracts and currency spot transactions included in the Fund’s policy relating to the investment of at least 80% of its net assets (including investment borrowings) will be limited to Asian Pacific currencies.

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. 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. The Fund’s past performance does not predict future performance.

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 was 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.

Understanding Your Fund Expenses

April 30, 2021 (Unaudited)

As a shareholder of First Trust RiverFront Dynamic Asia Pacific ETF, First Trust RiverFront Dynamic Developed International ETF, First Trust RiverFront Dynamic Europe ETF or First Trust RiverFront Dynamic Emerging Markets 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 (in U.S. dollars) 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 April 30, 2021.

Actual Expenses

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.

	Beginning Account Value November 1, 2020	Ending Account Value April 30, 2021	Annualized Expense Ratio Based on the Six-Month Period	Expenses Paid During the Six-Month Period (a)
First Trust RiverFront Dynamic Asia Pacific ETF (RFAP)
Actual	$1,000.00	$1,167.00	0.83%	$4.46
Hypothetical (5% return before expenses)	$1,000.00	$1,020.68	0.83%	$4.16
First Trust RiverFront Dynamic Developed International ETF (RFDI)
Actual	$1,000.00	$1,258.00	0.83%	$4.65
Hypothetical (5% return before expenses)	$1,000.00	$1,020.68	0.83%	$4.16
First Trust RiverFront Dynamic Europe ETF (RFEU)
Actual	$1,000.00	$1,302.60	0.83%	$4.74
Hypothetical (5% return before expenses)	$1,000.00	$1,020.68	0.83%	$4.16
First Trust RiverFront Dynamic Emerging Markets ETF (RFEM)
Actual	$1,000.00	$1,208.10	0.95%	$5.20
Hypothetical (5% return before expenses)	$1,000.00	$1,020.08	0.95%	$4.76

(a)	Expenses are equal to the annualized expense ratios as indicated in the table multiplied by the average account value over the period (November 1, 2020 through April 30, 2021), multiplied by 181/365 (to reflect the six-month period).

First Trust Exchange-Traded Fund III

April 30, 2021 (Unaudited)

1. Organization

First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Trust consists of seventeen funds that are currently offering shares. This report covers the four funds (each a “Fund” and collectively, the “Funds”) listed below. The shares of each Fund are listed and traded on The Nasdaq Stock Market LLC (“Nasdaq”).

First Trust RiverFront Dynamic Asia Pacific ETF – (ticker “RFAP”)

First Trust RiverFront Dynamic Developed International ETF – (ticker “RFDI”)

First Trust RiverFront Dynamic Europe ETF – (ticker “RFEU”)

First Trust RiverFront Dynamic Emerging Markets ETF – (ticker “RFEM”)

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. The investment objective of each Fund is to provide capital appreciation.

Under normal market conditions, RFAP seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of equity securities of Asian Pacific companies, including through investments in common stocks, depositary receipts, common and preferred shares of real estate investment trusts (“REITs”), and forward foreign currency contracts and currency spot transactions used to hedge the Fund’s exposure to the currencies in which the equity securities of such Asian Pacific companies are denominated.

Under normal market conditions, RFDI seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of equity securities of developed market companies, including through investments in common stocks, depositary receipts, common and preferred shares of REITs, and forward foreign currency contracts and currency spot transactions used to hedge the Fund’s exposure to the currencies in which the equity securities of such developed market companies are denominated.

Under normal market conditions, RFEU seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of equity securities of European companies, including through investments in common stocks, depositary receipts, common and preferred shares of REITs, and forward foreign currency contracts and currency spot transactions used to hedge the Fund’s exposure to the currencies in which the equity securities of such European companies are denominated.

Under normal market conditions, RFEM seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of equity securities of emerging market companies, including through investments in common stocks, depositary receipts, common and preferred shares of REITs, and forward foreign currency contracts and currency spot transactions used to hedge the Fund’s exposure to the currencies in which the equity securities of such emerging market companies are denominated.

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

2. Significant Accounting Policies

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

A. Portfolio Valuation

Each Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. 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.

First Trust Exchange-Traded Fund III

April 30, 2021 (Unaudited)

Each Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent 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 adopted by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act. 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, REITs, and other equity securities listed on any national or foreign exchange (excluding 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 principal market for such securities.

Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Trust’s Board of Trustees or its delegate, 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 type of security;
2)	the size of the holding;
3)	the initial cost of the security;
4)	transactions in comparable securities;
5)	price quotes from dealers and/or third-party pricing services;
6)	relationships among various securities;
7)	information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
8)	an analysis of the issuer’s financial statements; and
9)	the existence of merger proposals or tender offers that might affect the value of the security.

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; and
8)	whether the effects of the event are isolated or whether they affect entire markets, countries or regions.

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

Page 35

Notes to Financial Statements (Continued)

First Trust Exchange-Traded Fund III

April 30, 2021 (Unaudited)

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:

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

o	Quoted prices for similar investments in active markets.
o	Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund’s investments as of April 30, 2021, 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 except that certain dividends from foreign securities are recorded as soon as the information becomes available after the ex-dividend date. Interest income, if any, is recorded on the accrual basis.

Withholding taxes and tax reclaims on foreign dividends have been provided for in accordance with each Fund’s understanding of the applicable country’s tax rules and rates.

Distributions received from a Fund’s investments in 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 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 included 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 are 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 Distributions to Shareholders

Dividends from net investment income, if any, are declared and paid quarterly by each Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by each Fund, if any, are distributed at least annually.

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

The tax character of distributions paid by each Fund during the fiscal year ended October 31, 2020, was as follows:

	Distributions paid from Ordinary Income	Distributions paid from Capital Gains	Distributions paid from Return of Capital
First Trust RiverFront Dynamic Asia Pacific ETF	$ 396,562	$ —	$ —
First Trust RiverFront Dynamic Developed International ETF	3,529,632	—	—
First Trust RiverFront Dynamic Europe ETF	536,232	—	—
First Trust RiverFront Dynamic Emerging Markets ETF	1,856,301	—	399,153

As of October 31, 2020, the components of distributable earnings on a tax basis for each Fund were as follows:

	Undistributed Ordinary Income	Accumulated Capital and Other Gain (Loss)	Net Unrealized Appreciation (Depreciation)
First Trust RiverFront Dynamic Asia Pacific ETF	$ 56,707	$ (10,346,588)	$ 412,368
First Trust RiverFront Dynamic Developed International ETF	227,138	(81,836,524)	6,036,155
First Trust RiverFront Dynamic Europe ETF	165,383	(15,744,689)	748,223
First Trust RiverFront Dynamic Emerging Markets ETF	—	(25,260,032)	5,817,739

E. Income and Other Taxes

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

Certain countries assess a capital gains tax on securities sold in their local markets. This tax is accrued as the securities in these foreign markets appreciate in value and is paid at the time of sale to the extent a capital gain is realized. Taxes accrued on securities in an unrealized appreciation position are included in “Net change in unrealized appreciation (depreciation) on deferred foreign capital gains tax” on the Statements of Operations. The capital gains tax paid on securities sold is included in “Net realized gain (loss) on foreign capital gains tax” on the Statements of Operations.

India’s Finance Bill, 2018 (“Finance Bill, 2018”) was enacted into law on March 29, 2018 and amongst other provisions, it introduced a long-term capital gains tax beginning April 1, 2018. Long-term capital gains on the sale of listed shares in excess of INR 0.1 million are taxed at the rate of 10% (plus applicable surcharge and cess (which is a type of tax)) subject to satisfaction of certain conditions. Long-term capital gains accruing as of January 31, 2018 are considered exempt due to a grandfather clause in the provision. The aforesaid exemption from long-term capital gains tax is available with respect to shares acquired between October 1, 2004 and March 31, 2018 only if on such acquisitions Securities Transaction Tax (“STT”) was chargeable. Certain exceptions in this regard, such as acquisition of shares in a public offer, bonus, rights issued, etc. for which the condition of chargeability of STT on acquisition is not applicable, have been notified.

In the case of the sale of listed shares held by a Fund for one year or less, the income is classified as short-term capital gains and is taxable at 15% (plus applicable surcharge and cess) provided the shares are sold on the stock exchange and subjected to STT. For

Page 37

Table of Contents

Notes to Financial Statements (Continued)

First Trust Exchange-Traded Fund III

April 30, 2021 (Unaudited)

above purposes, the applicable rate of surcharge is 2% or 5% (depending on the level of income of the Fund). The Finance Bill, 2018 increases the cess imposed on the sum of tax and surcharge from 3% to 4%. The cess 4% rate is applied to the capital gains tax, resulting in a higher effective rate of capital gains tax.

Where the sale of shares is outside the stock exchange and not subject to STT, the long-term capital gains are taxed at 10% (plus applicable surcharge and cess) and short-term capital gains are taxed at 30% (plus applicable surcharge and cess). The Finance Bill, 2018, approves the carry forward of long-term capital losses to be offset against long-term capital gains. Short-term losses can be netted against both short-term gains and long-term gains.

Until March 31, 2020, dividends received by a Fund from Indian companies were exempt from tax in India because Indian companies were required to pay dividend distribution tax. The Indian Finance Act, 2020 has amended the dividend taxation framework effective April 1, 2020 and accordingly dividends would now be taxable in the hands of the shareholders at 20%, plus applicable surcharge and cess. Subsequent to the Indian Finance Act, 2020, “The Taxation and Other Laws (Relaxation and Amendment of Certain Provisions) Bill, 2020” (the “Bill”) was enacted into law and is effective retroactively to April 1, 2020. The Bill caps the maximum surcharge at 15% of the tax on dividend income earned by the Fund. The highest effective tax rate proposed for non-corporate entities on dividends will be 23.92%. Note, the Fund will not obtain relief under the US-India tax treaty as the treaty rate of 25% is higher than the domestic rate. Any excess taxes withheld can be off-set against capital gains tax liability during the year or claimed as a refund in the annual tax return.

Please note that the above description is based on current provisions of Indian law, and any change or modification made by subsequent legislation, regulation, or administrative or judicial decision could increase the Indian tax liability of a Fund and thus reduce the return to a Fund’s shareholders. There can be no assurance that the Indian tax authorities and/or regulators will not take a position contrary to the views expressed herein. If the Indian tax authorities and/or regulators take a position contrary to the views expressed herein, adverse unpredictable consequences may follow.

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. Taxable years ended 2017, 2018, 2019, and 2020 remain open to federal and state audit. As of April 30, 2021, 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.

The Funds intend to utilize provisions of the federal income tax laws, which allow them 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 Funds are 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, 2020, the Funds had non-expiring capital loss carryforwards for federal income tax purposes as follows:

	Non-Expiring Capital Loss Carryforward
First Trust RiverFront Dynamic Asia Pacific ETF	$ 10,346,588
First Trust RiverFront Dynamic Developed International ETF	81,836,524
First Trust RiverFront Dynamic Europe ETF	15,744,689
First Trust RiverFront Dynamic Emerging Markets ETF	25,260,032

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 supervising the selection and ongoing monitoring of the securities in each Fund’s portfolio, managing the Funds’ business affairs and providing certain administrative services necessary for the management of the Funds.

Pursuant to the Investment Management Agreement between First Trust and the Trust, First Trust supervises the investment of the Funds’ assets and is responsible for the expenses of each Fund including the cost of transfer agency, sub-advisory, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest,

Notes to Financial Statements (Continued)

First Trust Exchange-Traded Fund III

taxes, brokerage commissions, acquired fund fees and expenses, if any, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, expenses associated with the execution of portfolio transactions, and extraordinary expenses, which are paid by each respective Fund. RFAP, RFDI and RFEU have each agreed to pay First Trust an annual unitary management fee equal to 0.83% its average daily net assets. RFEM has agreed to pay First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. First Trust also provides fund reporting services to each Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.

RiverFront Investment Group, LLC (“RiverFront” or the “Sub-Advisor”) serves as the Funds’ sub-advisor and manages each Fund’s portfolio subject to First Trust’s supervision. The Sub-Advisor receives a monthly portfolio management fee calculated at an annual rate of 0.35% of each Fund’s average daily net assets that is paid by First Trust out of its investment advisory fee.

The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Funds. As custodian, BBH is responsible for custody of each Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of each Fund’s securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for each Fund.

4. Purchases and Sales of Securities

For the six months ended April 30, 2021, the cost of purchases and proceeds from sales of investment securities for each Fund, excluding short-term investments and in-kind transactions, were as follows:

	Purchases	Sales
First Trust RiverFront Dynamic Asia Pacific ETF	$ —	$ 110,873
First Trust RiverFront Dynamic Developed International ETF	588,493	1,163,645
First Trust RiverFront Dynamic Europe ETF	150,822	423,345
First Trust RiverFront Dynamic Emerging Markets ETF	372,934	251,824

For the six months ended April 30, 2021, the cost of in-kind purchases and proceeds from in-kind sales for each Fund were as follows:

	Purchases	Sales
First Trust RiverFront Dynamic Asia Pacific ETF	$ —	$ 2,738,244
First Trust RiverFront Dynamic Developed International ETF	12,005,217	8,776,527
First Trust RiverFront Dynamic Europe ETF	—	3,269,364
First Trust RiverFront Dynamic Emerging Markets ETF	—	—

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 will accept in exchange for a Creation Unit of the Fund’s shares. An Authorized Participant that wishes to effectuate a creation of a Fund’s shares deposits with the Fund the “basket” of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the Fund’s shares or sell them in the

Page 39

Table of Contents

Notes to Financial Statements (Continued)

First Trust Exchange-Traded Fund III

April 30, 2021 (Unaudited)

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, each 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 Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide 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 February 28, 2022.

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 to the Funds through the date the financial statements were issued, and has determined that there were the following subsequent events:

The Board of Trustees of RFAP approved the reorganization of RFAP into RFDI. The reorganization has also been approved by the Board of Trustees of RFDI. RFDI will be the surviving fund. Under the terms of the proposed transaction, which is expected to be tax-free, the assets of RFAP will be transferred to, and the liabilities of RFAP will be assumed by, RFDI, and shareholders of RFAP would receive shares of RFDI with a net asset value equal to the aggregate net asset value of the RFAP shares held by them. It is currently expected that the transaction will be consummated no later than the third quarter of 2021, subject to satisfaction of applicable regulatory requirements and approvals and customary closing conditions.

On May 13, 2021, First Trust New York Municipal High Income ETF, an additional series of the Trust, began trading under the symbol “FMNY” on the NYSE Arca, Inc.

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 funds without significant dilution of remaining investors’ interests in the funds. 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”).

At the April 26, 2021 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 20, 2020 through the Liquidity Committee’s annual meeting held on March 16, 2021 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 each Fund primarily holds assets that are highly liquid investments, the Funds have not adopted a highly liquid investment minimum.

Fund Performance Overview (Unaudited)

First Trust Institutional Preferred Securities and Income ETF (FPEI)

First Trust Institutional Preferred Securities and Income ETF’s (the “Fund”) investment objective is to seek total return and to provide current income. Under normal market conditions, the Fund invests at least 80% of its net assets (including investment borrowings) in institutional preferred securities (“Preferred Securities”) and income-producing debt securities (“Income Securities”). Preferred Securities are a type of equity security that have preference over common stock in the payment of distributions and the liquidation of a company’s assets, but are generally junior to all forms of the company’s debt, including both senior and subordinated debt. The Fund’s investments in Preferred Securities will primarily be in institutional preferred securities. Institutional preferred securities are targeted to institutional, rather than retail, investors, are generally traded over-the-counter and may also be known as “$1,000 par preferred securities.” They are typically issued in large, institutional lot sized by U.S. and non-U.S. financial services companies and other companies. While all income-producing debt securities will be categorized as “Income Securities” for purposes of the 80% test above, the Income Securities in which the Fund intends to invest as part of its principal investment strategy include hybrid capital securities, contingent capital securities, U.S. and non-U.S. corporate bonds and convertible securities.

Total returns for the period since inception are calculated from the inception date of the Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the period indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

Fund Performance Overview (Unaudited) (Continued)

First Trust Institutional Preferred Securities and Income ETF (FPEI) (Continued)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. 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. The Fund’s past performance does not predict future performance.

Understanding Your Fund Expenses

April 30, 2021 (Unaudited)

As a shareholder of the First Trust Institutional Preferred Securities and Income ETF (the “Fund”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended April 30, 2021.

Actual Expenses

Hypothetical Example for Comparison Purposes

	Beginning Account Value November 1, 2020	Ending Account Value April 30, 2021	Annualized Expense Ratio Based on the Six-Month Period	Expenses Paid During the Six-Month Period (a)
First Trust Institutional Preferred Securities and Income ETF (FPEI)
Actual	$1,000.00	$1,080.20	0.85%	$4.38
Hypothetical (5% return before expenses)	$1,000.00	$1,020.58	0.85%	$4.26

(a)	This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”), and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P., the Fund’s advisor. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At April 30, 2021, securities noted as such amounted to $112,509,611 or 31.5% of net assets.
(b)	Perpetual maturity.
(c)	This security is a contingent convertible capital security which may be subject to conversion into common stock of the issuer under certain circumstances. At April 30, 2021, securities noted as such amounted to $121,326,386 or 33.9% of net assets. Of these securities, 3.6% originated in emerging markets, and 96.4% originated in foreign markets.
(d)	Fixed-to-floating or fixed-to-variable rate security. The interest rate shown reflects the fixed rate in effect at April 30, 2021. At a predetermined date, the fixed rate will change to a floating rate or a variable rate.
(e)	This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the 1933 Act.
(f)	Floating or variable rate security.
(g)	This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A under the 1933 Act, and may be resold in transactions exempt from registration, normally to qualified institutional buyers (see Note 2C - Restricted Securities in the Notes to Financial Statements).
(h)	These notes are Senior Payment-in-kind (“PIK”) Toggle Notes whereby the issuer may, at its option, elect to pay interest on the notes (1) entirely in cash or (2) entirely in PIK interest. Interest paid in cash will accrue on the notes at a rate of 7.63% per annum (“Cash Interest Rate”) and PIK interest will accrue on the notes at a rate per annum equal to the Cash Interest Rate plus 75 basis points. For the six months ended April 30, 2021, this security paid all of its interest in cash.
(i)	Aggregate cost for financial reporting purposes approximates the aggregate cost for federal income tax purposes. As of April 30, 2021, the aggregate gross unrealized appreciation for all investments in which there was an excess of value over tax cost was $19,513,203 and the aggregate gross unrealized depreciation for all investments in which there was an excess of tax cost over value was $643,743. The net unrealized appreciation was $18,869,460.

First Trust Institutional Preferred Securities and Income ETF (FPEI)

April 30, 2021 (Unaudited)

1. Organization

The Trust currently consists of seventeen funds that are offering shares. This report covers the First Trust Institutional Preferred Securities and Income ETF (the “Fund”), which trades under the ticker “FPEI” on the NYSE Arca, Inc. 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. The investment objective of the Fund is to seek total return and to provide current income. Under normal market conditions, the Fund invests at least 80% of its net assets (including investment borrowings) in institutional preferred securities and income-producing debt securities, including hybrid capital securities, contingent capital securities, U.S. and non-U.S. corporate bonds and convertible securities. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.

2. Significant Accounting Policies

A. Portfolio Valuation

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.

Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

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.

1)	the type of security;
2)	the size of the holding;
3)	the initial cost of the security;
4)	transactions in comparable securities;
5)	price quotes from dealers and/or third-party pricing services;
6)	relationships among various securities;
7)	information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
8)	an analysis of the issuer’s financial statements; and
9)	the existence of merger proposals or tender offers that might affect the value of the security.

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; and
8)	whether the effects of the event are isolated or whether they affect entire markets, countries or regions.

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

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

o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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

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. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.

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.

D. Dividends and Distributions to Shareholders

Page 19

Table of Contents

Notes to Financial Statements (Continued)

First Trust Institutional Preferred Securities and Income ETF (FPEI)

April 30, 2021 (Unaudited)

Distributions from income and 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 by the Fund during the fiscal year ended October 31, 2020, was as follows:

Distributions paid from:
Ordinary income	$14,004,420
Capital gains	—
Return of capital	507,892

As of October 31, 2020, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income	$—
Accumulated capital and other gain (loss)	(5,714,555)
Net unrealized appreciation (depreciation)	4,807,338

E. Income Taxes

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. Taxable years ended 2017, 2018, 2019 and 2020 remain open to federal and state audit. As of April 30, 2021, 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, 2020, for federal income tax purposes, the Fund had $5,714,555 of capital loss carryforwards available to the extent provided by regulations to offset future capital gains.

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 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 supervising 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.
