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 any series of First Trust Exchange-Traded Fund (the “Trust”) described in this report (each such series is referred to as a “Fund” and collectively, as the “Funds”) to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

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

Shareholder Letter
First Trust Exchange-Traded Fund
Semi-Annual Letter from the Chairman and CEO
June 30, 2023
Dear Shareholders,
First Trust is pleased to provide you with the semi-annual report for certain series of the First Trust Exchange-Traded Fund (the “Funds”), which contains detailed information about the Funds for the six months ended June 30, 2023.
One economic topic that continues to dominate headlines is whether the Federal Reserve (the “Fed”) will be able to pull off a “soft landing” for the U.S. economy, raising interest rates just high enough to curb inflation, but not so high that they stunt economic growth and cause a recession. Historically, soft landings are exceedingly rare. Over the past 60 years, the Fed has only been able to orchestrate this phenomenon once. This occurred between February 1994 and February 1995 when the Fed doubled the Federal Funds target rate (upper bound), raising it from 3.0% to 6.0%. For comparative purposes, the Federal Funds target rate (upper bound) stood at 5.25% on June 30, 2023, a full 500 basis points above its most recent low of 0.25% on March 15, 2022. Inflation, as measured by the rate of change in the Consumer Price Index (“CPI”), appears to be declining. The CPI stood at 3.0% on June 30, 2023, substantially lower than its most recent peak of 9.1% on June 30, 2022. Despite the Fed’s tighter monetary policy, the U.S. economy continues to show resilience, with gross domestic product (“GDP”) growing in each of the past three quarters.
I am continually amazed by the efficiencies that technological advances can have on production. Take, for example, the recent interest in artificial intelligence (“AI”). The U.S. Census Bureau reported that construction spending by manufacturers in the U.S. has more than doubled in the past year, reaching an annual rate of nearly $190 billion in April 2023, according to Bloomberg. Manufacturing now accounts for close to 13% of all non-government construction, its highest share on record. A portion of the growth in U.S. manufacturing is due to the CHIPS and Science Act, which provided nearly $280 billion in funding to boost domestic research and manufacturing of semiconductors in the U.S. We have also seen the excitement regarding developments in AI drive the S&P 500® Index (the “Index”) higher this year. Year-to-date through June 30, 2023, the Index posted a total return of 16.89%. When the stock market increases by 20% or more from its most recent low, it is often referred to as a “bull market.” On June 8, 2023, the Index closed at 4,293.93, 20.04% above its most recent low of 3,577.03 (which occurred on October 12, 2022).
The U.S. economy has been resilient, posting positive changes to GDP even as monetary policy tightened significantly. That said, there are also economic indicators that point to the potential for weakness over the coming quarters. The Conference Board, a
non-profit business membership and research group organization, reported that its Leading Economic Index, which is composed of 10 economic indicators whose changes tend to precede changes in the overall economy, fell by 0.7% to a reading of 106.1 in June 2023, according to Reuters. The result represents the fifteenth consecutive monthly decline in the index, the longest streak of
month-over-month decreases since just before the financial crisis in 2007. From our perspective, even if the Fed can pull off a soft landing, it is likely to be a very bumpy ride.
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Funds again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

State of the Economy/Investing
As we head into the second half of 2023, a hot topic of discussion appears to be whether the Federal Reserve (the “Fed”) will resume interest rate hikes at their upcoming meeting on July 26, 2023. Central to this discussion is the pace of inflation. Inflation, as measured by the trailing 12-month rate of change in the Consumer Price Index, stood at 3.0% on June 30, 2023, a significant decline from its high of 9.1% where it stood on June 30, 2022 (the year prior), according to the U.S. Bureau of Labor Statistics. In what is known as a “soft landing,” the Fed intends to tighten monetary policy just enough to reduce inflation to 2.0%, but not so much that they cause a retraction in economic growth.
The latest growth forecast from the International Monetary Fund (“IMF”) released in July 2023 sees U.S. real gross domestic product (“GDP”) rising by 1.8% in 2023, up from its April 2023 estimate of 1.6%. The IMF notes that July’s upwardly revised real GDP reflects resilient consumer consumption in the first quarter of 2023, a trend they are quick to note is not likely to last. The IMF estimates that in 2024, U.S. real GDP could fall to just 1.0%. Overall, Advanced Economies are projected to register a 1.5% growth rate in 2023, before declining to 1.4% in 2024. Emerging Market and Developing Economies are projected to grow faster than Advanced Economies. The IMF estimates their growth rate to register 4.0% and 4.1% in 2023 and 2024, respectively.
U.S. Stocks and Bonds
The major U.S. stock indices delivered positive results over the past six months. The S&P 500®, S&P MidCap 400® and S&P SmallCap 600® Indices posted total returns of 16.89%, 8.84% and 6.03%, respectively, for the six-month period ended June 30, 2023. Seven of the eleven major sectors that comprise the S&P 500® Index were up on a total return basis. The top performer was the Information Technology sector, which was up 42.77%, while the worst showing came from the Utilities sector, which was down 5.69%.
Results were also positive in the U.S. bond market over the period. The top performing major debt group we track was long-term municipal bonds. The Bloomberg Municipal Bond:Long Bond (22+) Index posted a total return of 4.96% for the six-month period ended June 30, 2023. The worst-performing U.S. debt group that we track was intermediate U.S. Treasuries. The Bloomberg U.S. Treasury:Intermediate Index posted a total return of 1.10%. The yield on the benchmark 10-Year Treasury Note (“T-Note”) fell by just 4 basis points in the period to close at 3.84% on June 30, 2023, according to Bloomberg. For comparative purposes, the average yield on the 10-Year T-Note was 2.90% for the 10-year period ended June 30, 2023.
Foreign Stocks and Bonds
The broader foreign stock indices posted positive total returns over the past six months. Between December 30, 2022, and June 30, 2023, the MSCI World ex USA and MSCI Emerging Markets equity indices posted total returns of 11.29% (USD) and 4.89% (USD), respectively, according to Bloomberg. The major foreign bond indices were also up over the same period. The Bloomberg Global Aggregate Index of higher quality debt posted a total return of 1.43% (USD), while the Bloomberg EM Hard Currency Aggregate Index of emerging markets debt increased by 3.55% (USD), according to Bloomberg. The U.S. Dollar fell by just 0.59% over the past six months against a basket of major currencies, as measured by the U.S. Dollar Index.

On November 6, 2008, the Fund’s underlying index changed from the S&P REIT Composite Index to the S&P United States REIT Index.
Effective December 31, 2008, the S&P REIT Composite Index was discontinued. Therefore, the Fund’s performance and historical returns shown
for the periods prior to November 6, 2008 are not necessarily indicative of the performance that the Fund, based on its current Index, would have
generated. The inception date of the Index was June 30, 2008. Returns for the Index are only disclosed for those periods in which the Index was
in existence for the whole period.

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. The total returns would have been lower if certain fees had not been waived and expenses reimbursed by the Advisor.
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.

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 each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.
