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 Cboe VestSM Financial LLC (“Cboe Vest” 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 the series of First Trust Exchange-Traded Fund VIII (the “Trust”) described in this report (each such series is referred to as a “Fund” and collectively, as the “Funds”) to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and/or Sub- Advisor and their respective representatives only as of the date hereof. We undertake no obligation to publicly revise or update these forward-looking statements to reflect events and circumstances that arise after the date hereof.
Performance and Risk Disclosure
There is no assurance that any Fund described in this report will achieve its investment objective. Each Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund’s shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in a Fund. See “Risk Considerations” in the Additional Information section of this report for a discussion of certain other risks of investing in the Funds.
Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost.
The Advisor may also periodically provide additional information on Fund performance on each Fund’s webpage at www.ftportfolios.com.

Shareholder Letter
First Trust Exchange-Traded Fund VIII
Annual Letter from the Chairman and CEO
August 31, 2023
Dear Shareholders:
First Trust is pleased to provide you with the annual report for certain series of the First Trust Exchange-Traded Fund VIII (the “Funds”), which contains detailed information about the Funds for the twelve months ended August 31, 2023. Please note that all of the Funds were incepted after September 1, 2022, the start of the reporting period, so information in this letter and the report prior to those inception dates will not apply.
As many investors are aware, the Federal Reserve (the “Fed”) remains locked in a closely watched battle with stubbornly high inflation. At their most recent meeting (September 20, 2023), the Federal Open Market Committee voted to keep the Federal Funds target rate (upper bound) unchanged at 5.5%, marking the second pause in a series of eleven increases that started on March 16, 2022. To be sure, the Fed has made considerable progress in reducing rising prices but has yet to see inflation fall to its 2.0% goal. Inflation, as measured by the twelve month trailing change in the rate of the Consumer Price Index, stood at 3.7% on August 31, 2023, down from its most recent high of 9.1% set on June 30, 2022, but up from its most recent low of 3.0% set on June 30, 2023.
One impact of rising prices and higher interest rates is that Americans’ excess savings, defined as the difference between the savings rate during the COVID-19 pandemic recession and its pre-recession trend, appear to be nearly depleted. The Federal Reserve Bank of San Francisco estimates that by June 2023, U.S. households held less than $190 billion of the excess savings they accumulated after the onset of the pandemic recession. At the current pace, the bank estimates that these excess savings will be depleted sometime in the third quarter of 2023. For comparison, excess savings peaked at nearly $2.1 trillion in August 2021. In our view, these excess savings are one reason consumer spending has remained robust in the face of elevated prices. Once these savings are gone, we could see the consumer struggle to manage their debt burden, in our opinion. In a potential harbinger of things to come, delinquency rates have already begun to rise. Data from the Federal Reserve Bank of New York revealed that the rate of new credit card and new auto loan delinquencies stood at 7.2% and 7.3%, respectively, in the second quarter of 2023, surpassing pre-pandemic levels.
Suffice it to say, the U.S. economy has remained resilient, registering positive changes to gross domestic product (“GDP”) in each of the past four quarters. Brian Wesbury, Chief Economist at First Trust, expects this growth to continue, estimating third quarter 2023 GDP could increase by as much as 4.0%. That said, Mr. Wesbury also notes that another quarter of economic growth does not mean that a recession is off the table. Several economic metrics continue to enjoy favorable comparisons to COVID-19-era lockdowns and recent governmental incentives, such as the CHIPS and Science Act of 2022, could be providing a temporary boost to economic growth.
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.

Fund Performance Overview (Unaudited)
FT Cboe Vest U.S. Equity Moderate Buffer ETF - January (GJAN)
The investment objective of the FT Cboe Vest U.S. Equity Moderate Buffer ETF - January (the “Fund”) is to seek to provide investors with returns (before fees and expenses) that match the price return of the SPDR® S&P 500® ETF Trust (the “Underlying ETF”), up to a predetermined upside cap of 15.75% while providing a buffer (before fees and expenses) against the first 15% of Underlying ETF losses, over the period from January 23, 2023 to January 19, 2024 (the “Outcome Period”). Under normal market conditions, the Fund will invest substantially all of its assets in FLexible EXchange® Options (“FLEX Options”) that reference the price performance of the Underlying ETF. Subsequent Outcome Periods will begin on the day the prior Outcome Period ends and will end on the approximate one-year anniversary of that new Outcome Period. On the first day of each new Outcome Period, the Fund resets by investing in a new set of FLEX Options that are designed to provide a new cap for the new Outcome Period. This means that the cap will change for each Outcome Period based upon prevailing market conditions at the beginning of each Outcome Period. The Fund will be perpetually offered and not terminate after the current or any subsequent Outcome Period. An investor that purchases Fund shares other than on the first day of an Outcome Period and/or sells Fund shares prior to the end of an Outcome Period may experience results that are very different from the target outcomes sought by the Fund for that Outcome Period. The Fund is classified as non-diversified under the Investment Company Act of 1940, as amended. The shares of the Fund are listed and traded on the Cboe BZX Exchange, Inc., under the ticker symbol “GJAN.”

FT Cboe Vest U.S. Equity Moderate Buffer ETF - August (GAUG)
The investment objective of the FT Cboe Vest U.S. Equity Moderate Buffer ETF - August (the “Fund”) is to seek to provide investors with returns (before fees and expenses) that match the price return of the SPDR® S&P 500® ETF Trust (the “Underlying ETF”), up to a predetermined upside cap of 15.26% while providing a buffer (before fees and expenses) against the first 15% of Underlying ETF losses, over the period from August 21, 2023 to August 16, 2024 (the “Outcome Period”). Under normal market conditions, the Fund will invest substantially all of its assets in FLexible EXchange® Options (“FLEX Options”) that reference the price performance of the Underlying ETF. Subsequent Outcome Periods will begin on the day the prior Outcome Period ends and will end on the approximate one-year anniversary of that new Outcome Period. On the first day of each new Outcome Period, the Fund resets by investing in a new set of FLEX Options that are designed to provide a new cap for the new Outcome Period. This means that the cap will change for each Outcome Period based upon prevailing market conditions at the beginning of each Outcome Period. The Fund will be perpetually offered and not terminate after the current or any subsequent Outcome Period. An investor that purchases Fund shares other than on the first day of an Outcome Period and/or sells Fund shares prior to the end of an Outcome Period may experience results that are very different from the target outcomes sought by the Fund for that Outcome Period. The Fund is classified as non-diversified under the Investment Company Act of 1940, as amended. The shares of the Fund are listed and traded on the Cboe BZX Exchange, Inc., under the ticker symbol “GAUG.”

Notes to Fund Performance Overview (Unaudited)
Total returns for the periods since inception are calculated from the inception date of each Fund. “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 the Securities and Exchange Commission’s rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund’s NAV is calculated. 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.

Commentary
Market Recap
Each of the monthly FT Cboe Vest Target Outcome ETFs has an investment objective that seeks to provide investors with returns (before fees and expenses) that match those of a specified reference exchange-traded fund (“ETF”), the SPDR® S&P 500® ETF Trust or the iShares Russell 2000® ETF (the “Underlying ETF” or “Reference ETF”), up to a predetermined upside cap (after fees and expenses, excluding brokerage commissions, trading fees, taxes and extraordinary expenses not included in the Fund’s management fee), while providing a buffer against a specific level (before fees and expenses) of losses in the Reference ETF, over a specified time period.
During the 12-month period ended August 31, 2023 (the “Period”), stock markets generally rallied as central banks, including the U.S. Federal Reserve Bank (the “Fed”), raised interest rates in an attempt to reduce high inflation rates. The subsequent decline in inflation rates, combined with a resilient economy that has avoided recession and looks more likely to have a “soft landing,” encouraged the equity markets.
The S&P 500® Index, the well-known measure of U.S. large-cap stocks, ended the Period up 15.94%. Mid- and small-capitalization stocks, as measured by the S&P MidCap 400® Index and the Russell 2000® Small Cap Index, rose as well, gaining 10.71% and 4.65%, respectively, during the Period. The Nasdaq-100 Index®, a tech-heavy market measure, gained 27.44% during the Period. International markets gained as well, with broad foreign market indices such as MSCI EAFE Index and MSCI Emerging Markets Index rising by 17.92% and 1.25%, respectively, during the Period.
During the Period, the market continued to see substantial variations in returns across the eleven major sectors in the S&P 500® Index. The two best performing sectors were the Information Technology and Communication Services sectors, which gained 33.33% and 25.76%, respectively. The only two sectors to post losses over the Period were the Utility and Real Estate sectors, which lost 12.65% and 8.15%, respectively.
U.S. economic data was generally stronger than expected. Quarterly gross domestic product (“GDP”) reports showed the U.S. economy reversing direction and beginning to grow again after recording two declining quarters in the prior period. The four most

Annual Report
August 31, 2023 (Unaudited)
recent quarterly reports (third quarter 2022 through second quarter 2023) saw seasonally adjusted annualized rates of 3.2%, 2.6%, 2.0%, and 2.1%, sequentially. A recent Bloomberg survey of economists shows a consensus projection of 2.0% GDP growth for all of 2023 and 0.9% for all of 2024.
The U.S. unemployment rate began the Period at 3.7% (for August 2022) and ended the Period at 3.8% (for August 2023).  The rate remained below 4.0% in each of the twelve monthly reports while dropping as low as 3.4%, thus remaining very close to 50 year lows.
U.S inflation levels declined over the Period. The most recent (August 2023) Consumer Price Index report shows year-over-year inflation running at a 3.7% rate, down from 8.3% reported twelve months earlier. Housing prices in the U.S., which had increased dramatically over the last two years, were essentially flat (down just 0.02%) over the current period, based on the S&P CoreLogic Case-Shiller U.S. National Home Price Index. According to this index, home prices fell during the first half of the Period, but then turned upward in the latter half.
The Fed continued the interest rate hike cycle that it initiated in January 2022. Over the Period, the Fed raised the upper bound of its Federal Funds target rate from 2.5% to 5.5%. Interest rate hikes were more aggressive over the first half of the Period, and more muted over the second half. Fed Fund futures prices, as of this writing, suggest that market participants anticipate that the Fed may hike just one more quarter point this year, before reversing direction and cutting rates in 2024.
Market and Fund Outlook
Over the Period, implied volatilities in U.S. equity markets averaged about 25.4%, according to the Cboe S&P 500® 1-Year Volatility Index. This index is derived from option prices and estimates the market’s expectation of S&P 500® Index volatility for the next twelve months. As of the end of the Period, the index stands at 20.1%. For comparison purposes, the historical volatility of the S&P 500® Index since its inception in 1937 has been about 15.7%. We anticipate that implied volatilities will decline slightly over the coming year. Buffer strategies, such as those used in the FT Cboe Vest Funds, generally benefit from declining implied volatilities.
While most fixed income securities have seen their nominal yields increase during the Period, many still have relatively low real yields (i.e., nominal yield less the inflation rate.)  This continues to be a headwind for future fixed income returns. Because of this, many investors continue to reallocate away from fixed income investments.
The FT Cboe Vest Funds are an alternative that these investors should consider. The FT Cboe Vest Funds are designed to protect investors against varying levels of downside movements in their Reference ETF (e.g., SPY or IWM), while limiting the investor’s participation in larger upside moves in the Reference ETF. In the current low real yield environment, such Funds, in appropriate allocations, can be suitable alternatives to fixed income investments.
Performance Analysis
The following table provides information pertaining to recent caps and performance for the Period for each FT Cboe Vest Fund.
Each Fund’s cap is reset at the Fund’s annual reset date. The table shows the caps that were in effect both at the beginning of the Period and after the annual reset date that occurred within the Period. Both of these caps are shown pre- and post- expenses. Funds that were launched within the Period do not yet have new caps, as they have not yet reached their first annual reset date.
Each Fund’s performance may be impacted by a number of factors. These factors include changes in each of: the level of the Reference ETF, the Reference ETF’s dividends, interest rates, implied volatility, and time to option expiration. Generally, changes in the level of the Reference ETF are the primary factor, but the other factors can also contribute significantly to Fund performance. Additionally, fees and expenses will impact Fund performance.

Understanding Your Fund Expenses
August 31, 2023 (Unaudited)
As a shareholder of FT Cboe Vest U.S. Equity Moderate Buffer ETF - January, FT Cboe Vest U.S. Equity Moderate Buffer ETF - February, FT Cboe Vest U.S. Equity Moderate Buffer ETF - March, FT Cboe Vest U.S. Equity Moderate Buffer ETF - April, FT Cboe Vest U.S. Equity Moderate Buffer ETF - May, FT Cboe Vest U.S. Small Cap Moderate Buffer ETF - May, FT Cboe Vest U.S. Equity Moderate Buffer ETF - June, FT Cboe Vest U.S. Equity Moderate Buffer ETF - July, FT Cboe Vest U.S. Equity Moderate Buffer ETF - August or FT Cboe Vest U.S. Small Cap Moderate Buffer ETF - August (each a “Fund” and collectively, the “Funds”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Funds and to compare these costs with the ongoing costs of investing in other funds.
The Example is based on an investment of $1,000 invested at the beginning of the period (or since inception) and held through the six-month (or shorter) period ended August 31, 2023.
Actual Expenses
The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Period” to estimate the expenses you paid on your account during this six-month (or shorter) 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.
