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 TCW Investment Management Company LLC ("TCW" 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

                        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.

                            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

SHAREHOLDER LETTER

                     FIRST TRUST EXCHANGE-TRADED FUND VIII
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                               FEBRUARY 28, 2022

Dear Shareholders:

First Trust is pleased to provide you with the semi-annual report for certain
series of the First Trust Exchange-Traded Fund VIII (the "Funds"), which
contains detailed information about the Funds for the six-month period ended
February 28, 2022.

Interest rates, bond yields and inflation are trending higher in the U.S., and
perhaps what matters most is that all three are moving in tandem, which has not
happened for quite some time. To start, let us focus on bond yields, which, like
interest rates and inflation, have traded at or near their historic lows for
many years. Over the past decade, we have seen the yield on the 10-Year Treasury
Note ("T-Note") climb from its artificial lows to the 3.00% level on two
occasions only to have it reverse course soon thereafter. In 2013, the yield on
the benchmark government bond rose from 1.75% at the start of the year to 3.03%
at the close of trading on December 31, 2013. One year later it stood at 2.17%.
In 2018, the yield rose from 2.41% at the start of the year to a 2018 high of
3.24% on November 8, 2018. At the end of 2019, it yielded 1.92%. In 2022, it has
reached as high as 2.78% (on April 11), representing a significant move from
1.51% at the start of the year. The point is that we have endured substantial
upward moves in the yield on the 10-Year T-Note, but they were not sustained.

Short-term interest rates, as controlled by the Federal Reserve (the "Fed") via
its Federal Funds target rate, only accompanied bond yields higher in one of
those two instances. In 2013, bond yields rose but the Fed did not raise
short-term interest rates at all. In 2017 and 2018, the Fed executed multiple
interest rate hikes, but reversed course in 2019, undoing the entirety of its
2017-2018 tightening phase. On March 16, 2022, the Fed initiated a 25-basis
point ("bps") hike in the Federal Funds target rate. The median member of the
Federal Open Market Committee is signaling another six hikes, totaling 150 bps,
through year-end, according to Brian Wesbury, Chief Economist at First Trust.
That would equate to 175 bps in aggregate in 2022. The Fed also signaled it
could raise interest rates an additional 75-100 bps in 2023. So, for all intents
and purposes, unless something dramatic happens, such as an escalation of the
war between Russia and Ukraine, we believe interest rates are heading much
higher. With respect to inflation, as measured by the Consumer Price Index
("CPI"), it was essentially a non-event when bond yields rose in 2013 and 2018.
The year-over-year changes in the CPI in 2013 and 2018 were 1.5% and 1.9%,
respectively, according to data from the U.S. Bureau of Labor Statistics. The
CPI has averaged 3.0% per year since 1926. In February 2022, the CPI stood at
7.9%. The last time it was this high was 1982.

The current climate for interest rates, bond yields and inflation, indicates
that this time around could be different than what we experienced in 2013 and
2018. By that I mean that higher levels of all three might be sustainable.
Having said that, I do not believe that investors need to shift into panic mode.
The Fed's guidance is reassuring to us in that, as of now, it intends to raise
short-term interest rates slowly and methodically. While we believe the bond
market may be in for a bumpy ride over the next year or so, higher rates and
yields are not necessarily death knells for the stock market. In general, I
believe that investors should be able to make better decisions about where to
position their money moving forward thanks to the in-depth guidance from the
Fed. It could not be more transparent, in my opinion.

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

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

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.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS

Information showing the number of days the market price of the Fund's shares was
greater (at a premium) and less (at a discount) than the Fund's net asset value
for the most recently completed year, and the most recently completed calendar
quarters since that year (or life of the Fund, if shorter) is available at
https://www.ftportfolios.com/Retail/etf/home.aspx.

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.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS

Information showing the number of days the market price of the Fund's shares was
greater (at a premium) and less (at a discount) than the Fund's net asset value
for the most recently completed year, and the most recently completed calendar
quarters since that year (or life of the Fund, if shorter) is available at

FIRST TRUST TCW SECURITIZED PLUS ETF (DEED)

The First Trust TCW Securitized Plus ETF seeks to maximize long-term total
return. Under normal market conditions, the Fund will invest at least 80% of its
net assets (including investment borrowings) in securitized debt securities,
including asset-backed securities, residential and commercial mortgage-backed
securities and collateralized loan obligations (CLOs). The Fund's investment
sub-advisor, TCW Investment Management Company LLC ("TCW" or the "Sub-Advisor")
seeks to outperform the Bloomberg U.S. Mortgage-Backed Securities Index over
time through the utilization of independent, bottom-up research to identify
securities that are relatively undervalued. Under normal conditions, the Fund's
average portfolio duration varies within two years (plus or minus) of the
portfolio duration of the securities comprising the Bloomberg U.S.
Mortgage-Backed Securities Index. As a separate measure, there is no limit on
the weighted average maturity of the Fund's portfolio. While maturity refers to
the expected life of a security, duration is a measure of the expected price
volatility of a debt security as a result of changes in market rates of
interest. The Fund may utilize listed and over-the-counter derivatives
instruments. Shares of the Fund are listed on The NYSE Arca, Inc. under the
ticker symbol "DEED."

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.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS

Information showing the number of days the market price of the Fund's shares was
greater (at a premium) and less (at a discount) than the Fund's net asset value
for the most recently completed year, and the most recently completed calendar
quarters since that year (or life of the Fund, if shorter) is available at

FIRST TRUST TCW EMERGING MARKETS DEBT ETF (EFIX)

The First Trust TCW Emerging Markets Debt ETF (the "Fund") seeks to provide high
total return from current income and capital appreciation. Under normal market
conditions, the Fund will invest at least 80% of its net assets (including
investment borrowings) in debt securities issued or guaranteed by companies,
financial institutions and government entities located in emerging market
countries. An "emerging market country" is a country that, at the time the Fund
invests in the related security or instrument, is classified as an emerging or
developing economy by any supranational organization such as the World Bank or
the United Nations, or related entities, or is considered an emerging market
country for purposes of constructing a major emerging market securities index.
The Fund's investments include, but are not limited to, debt securities issued
by sovereign entities, quasi-sovereign entities and corporations.
"Quasi-Sovereign" refers to an entity that is either 100% owned by a sovereign
entity or whose debt is 100% guaranteed by a sovereign entity. The Fund may
invest up to 25% of its net assets in securities issued by corporations in
emerging market countries that are not Quasi-Sovereign entities. The Fund will
invest at least 90% of its assets in dollar-denominated securities. The Fund may
utilize listed and over-the-counter derivatives instruments. Shares of the Fund
are listed on The NYSE Arca, Inc. under the ticker symbol "EFIX."

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 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.

FIRST TRUST EXCHANGE-TRADED FUND VIII
UNDERSTANDING YOUR FUND EXPENSES
FEBRUARY 28, 2022 (UNAUDITED)

As a shareholder of First Trust TCW Opportunistic Fixed Income ETF, First Trust
TCW Unconstrained Plus Bond ETF, First Trust TCW Securitized Plus ETF or First
Trust TCW Emerging Markets Debt ETF (each a "Fund" and collectively, the
"Funds"), you incur two types of costs: (1) transaction costs; and (2) ongoing
costs, including management fees, distribution and/or service (12b-1) fees, if
any, and other Fund expenses. This Example is intended to help you understand
your ongoing costs of investing in the Funds and to compare these costs with the
ongoing costs of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended February 28, 2022.

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on 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.

FIRST TRUST TCW OPPORTUNISTIC FIXED INCOME ETF (FIXD)
PORTFOLIO OF INVESTMENTS (CONTINUED)
FEBRUARY 28, 2022 (UNAUDITED)

(a)   Security whose principal value is adjusted in accordance with changes to
      the country's Consumer Price Index. Interest is calculated on the basis of
      the current adjusted principal value.

(b)   All or a portion of this security is part of a mortgage dollar roll
      agreement (see Note 2K - Mortgage Dollar Rolls in the Notes to Financial
      Statements).

(c)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of 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 (the "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 February 28, 2022, securities noted
      as such amounted to $960,056,341 or 19.3% of net assets.

(d)   Floating or variable rate security.

(e)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at February 28, 2022. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(f)   When-issued security. The interest rate shown reflects the rate in effect
      at February 28, 2022. Interest will begin accruing on the security's first
      settlement date.

(g)   Zero coupon security.

(h)   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).

(i)   Pursuant to procedures adopted by the Trust's Board of Trustees, this
      security has been determined to be illiquid by First Trust Advisors L.P.
      (the "Advisor").

(j)   Step-up security. A security where the coupon increases or steps up at a
      predetermined date.

(k)   Collateral Strip Rate security. Coupon is based on the weighted net
      interest rate of the investment's underlying collateral. The interest rate
      resets periodically.

(l)   Weighted Average Coupon security. Coupon is based on the blended interest
      rate of the underlying holdings, which may have different coupons. The
      coupon may change in any period.

(m)   This security's value was determined using significant unobservable inputs
      (see Note 2A - Portfolio Valuation in the Notes to Financial Statements).

(n)   This security is fair valued by the Advisor's Pricing Committee in
      accordance with procedures adopted by the Trust's Board of Trustees, and
      in accordance with provisions of the Investment Company Act of 1940, as
      amended. At February 28, 2022, securities noted as such are valued at
      $12,776,010 or 0.3% of net assets.

(o)   This security may be resold to qualified foreign investors and foreign
      institutional buyers under Regulation S of the 1933 Act.

(p)   Senior Floating-Rate Loan Interests ("Senior Loans") in which the Fund
      invests generally pay interest at rates which are periodically
      predetermined by reference to a base lending rate plus a premium. These
      base lending rates are generally (i) the lending rate offered by one or
      more major European banks, such as the LIBOR, (ii) the Secured Overnight
      Financing Rate ("SOFR") obtained from the U.S. Department of the
      Treasury's Office of Financial Research, (iii) the prime rate offered by
      one or more United States banks or (iv) the certificate of deposit rate.
      Certain Senior Loans are subject to a LIBOR or SOFR floor that establishes
      a minimum LIBOR or SOFR rate. When a range of rates is disclosed, the Fund
      holds more than one contract within the same tranche with identical LIBOR
      or SOFR period, spread and floor, but different LIBOR or SOFR reset dates.

(q)   Senior Loans generally are subject to mandatory and/or optional
      prepayment. As a result, the actual remaining maturity of Senior Loans may
      be substantially less than the stated maturities shown.

(r)   The issuer will pay interest on the loans in cash and in Payment-In-Kind
      ("PIK") interest. Interest paid in cash will accrue at the rate of 7.00%
      per annum ("Cash Interest Rate") and PIK interest will accrue on the loan
      at the rate of 8.25% per annum. For the six months ended February 28,
      2022, the Fund received a portion of the interest in cash and PIK interest
      with a principal value of $137,705 for Cineworld Group PLC.

(s)   Non-income producing security.

(t)   Rate shown reflects yield as of February 28, 2022.

(a)   Collateral Strip Rate security. Coupon is based on the weighted net
      interest rate of the investment's underlying collateral. The interest rate
      resets periodically.

(b)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of 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 (the "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 February 28, 2022, securities noted
      as such amounted to $359,127,482 or 33.3% of net assets.

(c)   Step-up security. A security where the coupon increases or steps up at a
      predetermined date. The coupon rate is determined based on the underlying
      investments. The coupon rate resets periodically.

(d)   Floating or variable rate security.

(e)   Weighted Average Coupon security. Coupon is based on the blended interest
      rate of the underlying holdings, which may have different coupons. The
      coupon may change in any period.

(f)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at February 28, 2022. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(g)   Perpetual maturity.

(h)   When-issued security. The interest rate shown reflects the rate in effect
      at February 28, 2022. Interest will begin accruing on the security's first
      settlement date.

(i)   Zero coupon security.

(j)   This security, sold within the terms of a private placement memorandum, is

      and may be resold in transactions exempt from registration, normally to

                     FIRST TRUST EXCHANGE-TRADED FUND VIII
                         FEBRUARY 28, 2022 (UNAUDITED)


                                1. ORGANIZATION

First Trust Exchange-Traded Fund VIII (the "Trust") is an open-end management
investment company organized as a Massachusetts business trust on February 22,
2016, 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 fifty-five funds that are offering shares. This
report covers the four funds (each a "Fund" and collectively, the "Funds")
listed below:

      First Trust TCW Opportunistic Fixed Income ETF - (The Nasdaq Stock Market
         LLC ("Nasdaq") ticker "FIXD")
      First Trust TCW Unconstrained Plus Bond ETF - (NYSE Arca, Inc. ("NYSE
         Arca") ticker "UCON")
      First Trust TCW Securitized Plus ETF - (NYSE Arca ticker "DEED")
      First Trust TCW Emerging Markets Debt ETF - (NYSE Arca ticker "EFIX")

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. FIXD's, UCON's, and
DEED's investment objective is to seek to maximize long-term total return.
EFIX's investment objective is to seek to provide high total return from current
income and capital appreciation. Each of FIXD and UCON seeks to achieve its
investment objective by investing, under normal market conditions, at least 80%
of its net assets (including investment borrowings) in fixed income securities.
DEED seeks to achieve its investment objective by investing, under normal market
conditions, at least 80% of its net assets (including investment borrowings) in
securitized debt securities. EFIX seeks to achieve its investment objective by
investing, under normal market conditions, at least 80% of its net assets
(including investment borrowings) in debt securities issued or guaranteed by
companies, financial institutions and government entities located in emerging
market countries.

                       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. Domestic debt securities and 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 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.

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:

      Corporate bonds, corporate notes, U.S. government securities,
      mortgage-backed securities, asset-backed securities, municipal securities,
      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;


                                                                         Page 99

                         FEBRUARY 28, 2022 (UNAUDITED)

      5) benchmark securities;

      6) bids and offers; and

      7) reference data including market research publications.

      Common stocks 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.

      Options on swaps ("swaptions") are valued by a third-party pricing service
      using a mathematical model, which incorporates a number of market data
      factors, such as the trades and prices of the underlying instruments.

      Shares of open-end funds are valued at fair value which is based on NAV
      per share.

      Senior Floating-Rate Loan Interests ("Senior Loans")(1) are not listed on
      any securities exchange or board of trade. Senior Loans are typically
      bought and sold by institutional investors in individually negotiated
      private transactions that function in many respects like an
      over-the-counter secondary market, although typically no formal
      market-makers exist. This market, while having grown substantially since
      its inception, generally has fewer trades and less liquidity than the
      secondary market for other types of securities. Some Senior Loans have few
      or no trades, or trade infrequently, and information regarding a specific
      Senior Loan may not be widely available or may be incomplete. Accordingly,
      determinations of the market value of Senior Loans may be based on
      infrequent and dated information. Because there is less reliable,
      objective data available, elements of judgment may play a greater role in
      valuation of Senior Loans than for other types of securities. Typically,
      Senior Loans are valued using information provided by a third-party
      pricing service. The third-party pricing service primarily uses
      over-the-counter pricing from dealer runs and broker quotes from
      indicative sheets to value the Senior Loans.

      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.

      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.

      Exchange-traded options contracts are valued at the closing price in the
      market where such contracts are principally traded. If no closing price is
      available, exchange-traded options contracts are fair valued at the mean
      of their most recent bid and asked price, if available, and otherwise at
      their closing bid price.

      Swaps are fair valued utilizing quotations provided by a third-party
      pricing service or, if the third-party pricing service does not provide a
      value, by quotes provided by the selling dealer or financial institution.

      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.

                     FIRST TRUST EXCHANGE-TRADED FUND VIII
                         FEBRUARY 28, 2022 (UNAUDITED)

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 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 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 a security;

       4) the financial statements of the issuer;

       5) the credit quality and cash flow of the issuer, based on TCW
          Investment Management Company LLC's ("TCW" or the "Sub-Advisor") 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 of the
          issuer, 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 government
          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.

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 the securities denominated in foreign
currencies is converted into U.S. dollars using exchange rates determined daily
as of the close of regular trading on the NYSE.

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

      o     Level 1 - Level 1 inputs are quoted prices in active markets for
            identical investments. An active market is a market in which
            transactions for the investment occur with sufficient frequency and
            volume to provide pricing information on an ongoing basis.

      o     Level 2 - Level 2 inputs are observable inputs, either directly or
            indirectly, and include the following:

            o     Quoted prices for similar investments in active markets.

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

            o     Inputs other than quoted prices that are observable for the
                  investment (for example, interest rates and yield curves
                  observable at commonly quoted intervals, volatilities,
                  prepayment speeds, loss severities, credit risks, and default
                  rates).

            o     Inputs that are derived principally from or corroborated by
                  observable market data by correlation or other means.

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value each Fund's investments as of February 28, 2022, is
included with each Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                     FIRST TRUST EXCHANGE-TRADED FUND VIII
                         FEBRUARY 28, 2022 (UNAUDITED)

The United Kingdom's Financial Conduct Authority (the "FCA"), which regulates
the London Interbank Offered Rates ("LIBOR") announced on March 5, 2021 that it
intended to phase-out all LIBOR reference rates, beginning December 31, 2021.
Since that announcement, the FCA has ceased publication of all non-USD LIBOR
reference rates and the 1-week and 2-month USD LIBOR reference rates as of
December 31, 2021. The remaining USD LIBOR settings will cease to be published
or no longer be representative immediately after June 30, 2023. The
International Swaps and Derivatives Association, Inc. ("ISDA") confirmed that
the FCA's March 5, 2021 announcement of its intention to cease providing LIBOR
reference rates, constituted an index cessation event under the Interbank
Offered Rates ("IBOR") Fallbacks Supplement and the ISDA 2020 IBOR Fallbacks
Protocol for all 35 LIBOR settings and confirmed that the spread adjustment to
be used in ISDA fallbacks was fixed as of the date of the announcement.

In the United States, the Alternative Reference Rates Committee (the "ARRC"), a
group of market participants convened by the Board of Governors of the Federal
Reserve System and the Federal Reserve Bank of New York in cooperation with
other federal and state government agencies, has since 2014 undertaken efforts
to identify U.S. dollar reference interest rates as alternatives to LIBOR and to
facilitate the mitigation of LIBOR-related risks. In June 2017, the ARRC
identified the Secured Overnight Financing Rate ("SOFR"), a broad measure of the
cost of cash overnight borrowing collateralized by U.S. Treasury securities, as
the preferred alternative for U.S. dollar LIBOR. The Federal Reserve Bank of New
York began daily publishing of SOFR in April 2018. There is no assurance that
any alternative reference rate, including SOFR, will be similar to or produce
the same value or economic equivalence as LIBOR or that instruments using an
alternative rate will have the same volume or liquidity.

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

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.

Securities purchased or sold on a when-issued, delayed-delivery or forward
purchase commitment basis may have extended settlement periods. The value of the
security so purchased is subject to market fluctuations during this period. Each
Fund maintains liquid assets with a current value at least equal to the amount
of its when-issued, delayed-delivery or forward purchase commitments until
payment is made. At February 28, 2022, FIXD, UCON, and DEED held $21,686,856,
$10,936,228 and $2,591,955, respectively, of when-issued or delayed-delivery
securities. At February 28, 2022, FIXD, UCON, and DEED held $1,103,710,467,
$135,636,839 and $151,514,301, respectively, of forward purchase commitments.

C. RESTRICTED SECURITIES

FIXD, UCON, and DEED invest 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 February 28, 2022, FIXD, UCON,
and DEED 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.
Each 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.

                         FEBRUARY 28, 2022 (UNAUDITED)

D. FUTURES CONTRACTS

Each 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 a 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 a
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, a 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 Statements of Operations.

Upon entering into a futures contract, a 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 contacts 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 Statements of Operations. Pursuant to the contract, a Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin
and are included in "Variation margin" receivable or payable on the Statements
of Assets and Liabilities. If market conditions change unexpectedly, a Fund may
not achieve the anticipated benefits of the futures contract and may realize a
loss. The use of futures contracts involves the risk of imperfect correlation in
movements in the price of the futures contracts, interest rates and the
underlying instruments.

E. FORWARD FOREIGN CURRENCY CONTRACTS

Each 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. Each 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 a 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 (depreciation) on forward foreign
currency contracts" on the Statements 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
Statements of Operations. When the forward contract is closed, a 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 Statements of Operations. Risks arise from
the possible inability of Counterparties to meet the terms of their contracts
and from movement in currency and securities values and interest rates. Due to
the risks, a Fund could incur losses in excess of the net unrealized value shown
on the forward foreign currency contracts table in the Fund's Portfolio of
Investments. In the event of default by the Counterparty, a 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, a 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.

F. SWAP AGREEMENTS

Each Fund may enter into swap agreements. A swap is a financial instrument that
typically involves the exchange of cash flows between two parties on specified
dates (settlement dates), where the cash flows are based on agreed upon prices,
rates, etc. Payment received or made by the Fund for interest rate swaps, if
any, are recorded on the Statements of Operations as "Net realized gain (loss)
on swap contracts." When an interest rate swap is terminated, the Fund will
record a realized gain or loss equal to the difference between the proceeds from
(or cost of) the closing transaction and the Fund's basis in the contract, if
any. Generally, the basis of the contracts, if any, is the premium received or
paid. Swap agreements are individually negotiated and involve the risk of the
potential inability of the Counterparties to meet the terms of the agreement. In
connection with these agreements, cash and securities may be identified as
collateral in accordance with the terms of the respective swap agreements to
provide assets of value and recourse in the event of default under the swap
agreement or bankruptcy/insolvency of a party to the swap agreement. In the
event of a default by a Counterparty, the Fund will seek withdrawal of the
collateral and may incur certain costs exercising its rights with respect to the
collateral. 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.

Swap agreements may increase or decrease the overall volatility of the
investments of the Fund. The performance of swap agreements may be affected by
changes in the specific interest rate, security, currency, or other factors that
determine the amounts of payments due to and from the Fund. The Fund's maximum
interest rate risk to meet its future payments under swap agreements is equal to


                                                                        Page 103

                         FEBRUARY 28, 2022 (UNAUDITED)

the total notional amount as shown on the Portfolio of Investments. The notional
amount represents the U.S. dollar value of the contract as of the day of the
opening transaction or contract reset. When the Fund enters into a swap
agreement, any premium paid is included in "Swap contracts, at value" on the
Statements of Assets and Liabilities.

FIXD and UCON held interest rate swap agreements at February 28, 2022. An
interest rate swap agreement involves the Fund's agreement to exchange a stream
of interest payments for another party's stream of cash flows. Interest rate
swaps do not involve the delivery of securities or other underlying assets or
principal. Accordingly, the risk of loss with respect to interest rate swaps is
limited to the net amount of interest payments that the Fund is contractually
obligated to make.

G. OPTIONS AND SWAPTIONS

FIXD may invest in option contracts to adjust its exposure to interest rate
risk. The primary risk associated with purchasing options is that the value of
the underlying investments may move in such a way that the option is
out-of-the-money (the exercise price of the option exceeds the value of the
underlying investment), the position is worthless at expiration, and the Fund
loses the premium paid. The primary risk associated with selling options is that
the value of the underlying investments may move in such a way that the option
is in-the money (the exercise price of the option exceeds the value of the
underlying investment), the counterparty exercises the option, and the Fund
loses an amount equal to the market value of the option written less the premium
received.

FIXD invests in options on swaps (swaptions), which are transacted
over-the-counter ("OTC") and not on an exchange. The purchaser and writer of a
swaption is buying or granting the right to enter into a previously agreed upon
interest rate or credit default swap agreement (interest rate risk and/or credit
risk) at any time before the expiration of the option. Unlike exchange-traded
options, which are standardized with respect to the underlying instrument,
expiration date, contract size, and strike price, the terms of OTC options
generally are established through negotiation with the other party to the option
contract. Although this type of arrangement allows the purchaser or writer
greater flexibility to tailor an option to its needs, OTC options have the risk
of the potential inability of counterparties to meet the terms of their
contracts. The Fund's maximum equity price risk for purchased options is limited
to the premium initially paid.

FIXD may purchase or write (sell) put and call options on futures contracts and
enter into closing transactions with respect to such options to terminate an
existing position. A futures option gives the holder the right, in return for
the premium paid, to assume a long position (call) or short position (put) in a
futures contract at a specified exercise price prior to the expiration of the
option. Upon exercise of a call option, the holder acquires a long position in
the futures contract and the writer is assigned the opposite short position. In
the case of a put option, the opposite is true. Prior to exercise or expiration,
a futures contract may be closed out by an offsetting purchase or sale of a
futures option of the same series. Options are marked-to-market daily and their
value is affected by changes in the value of the underlying security, changes in
interest rates, changes in the actual or perceived volatility of the securities
markets and the underlying securities, and the remaining time to the option's
expiration. The value of options may also be adversely affected if the market
for the options becomes less liquid or the trading volume diminishes.

When a Fund purchases a call or put option, the premium paid represents the cost
of the call or put option, which is included in "Options contracts purchased, at
value" on the Statements of Assets and Liabilities. When a Fund writes (sells)
an option, an amount equal to the premium received by the Fund is included in
"Options contracts written, at value" on the Statements of Assets and
Liabilities. Options are marked-to-market daily and their value will be affected
by changes in the value and dividend rates of the underlying equity securities,
changes in interest rates, changes in the actual or perceived volatility of the
securities markets and the underlying equity securities and the remaining time
to the options' expiration. The value of options may also be adversely affected
if the market for the options becomes less liquid or trading volume diminishes

When a Fund purchases a call or put swaption, the premium paid represents the
cost of the call or put swaption, which is included in "Swaptions contracts
purchased, at value" on the Statements of Assets and Liabilities and is
subsequently adjusted daily to the current market value of the option purchased.
Fluctuations in the value of the swaptions are recorded in the Statements of
Operations as unrealized appreciation (depreciation) until expired, closed, or
exercised, at which time realized gains (losses) are recognized. If a Fund
elects to allow a put swaption to expire, then the interest rate risk for
purchased swaptions is limited to the premium initially paid. Any gain or loss
on swaptions would be included in "Purchased swaptions contracts" on the
Statements of Operations.

H. OFFSETTING ON THE STATEMENTS 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
Statements 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 a 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.

                     FIRST TRUST EXCHANGE-TRADED FUND VIII
                         FEBRUARY 28, 2022 (UNAUDITED)

For financial reporting purposes, the Funds do not offset financial assets and
financial liabilities that are subject to master netting arrangements ("MNAs")
or similar agreements on the Statements 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.

The Funds do not have the right to offset financial assets and financial
liabilities related to options and swaptions contracts, forward foreign currency
contracts, futures contracts or swap contracts on the Statements of Assets and
Liabilities.

I. 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
shown in "Net change in unrealized appreciation (depreciation) on investments"
on the Statements of Operations. Net realized foreign currency gains and losses
include the effect of changes in exchange rates between trade date and
settlement date on investment security transactions, foreign currency
transactions and interest and dividends received and 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
fluctuation in exchange rates between the initial purchase settlement date and
subsequent sale trade date for fixed-income securities is included in "Net
realized gain (loss) on investments" on the Statements of Operations.

J. INTEREST-ONLY SECURITIES

An interest-only security ("IO Security") is the interest-only portion of a
mortgage-backed security that receives some or all of the interest portion of
the underlying mortgage-backed security and little or no principal. A reference
principal value called a notional value is used to calculate the amount of
interest due to the IO Security. IO Securities are sold at a deep discount to
their notional principal amount. Generally speaking, when interest rates are
falling and prepayment rates are increasing, the value of an IO Security will
fall. Conversely, when interest rates are rising and prepayment rates are
decreasing, generally the value of an IO Security will rise. These securities,
if any, are identified on each Fund's Portfolio of Investments.

K. MORTGAGE DOLLAR ROLLS

Each Fund may invest, without limitation, in mortgage dollar rolls. The Funds
intend to enter into mortgage dollar rolls only with high quality securities
dealers and banks, as determined by the Funds' Sub-Advisor. In a mortgage dollar
roll, a Fund will sell (or buy) mortgage-backed securities for delivery on a
specified date and simultaneously contract to repurchase (or sell) substantially
similar (same type, coupon and maturity) securities on a future date. Mortgage
dollar rolls are recorded as separate purchases and sales in a Fund.

L. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

Distributions in cash may be reinvested automatically in additional whole shares
only if the broker through whom the shares were purchased makes such option
available. Such shares will generally be reinvested by the broker based upon the
market price of those shares and investors may be subject to customary brokerage
commissions charged by the broker.

Distributions from net investment income and realized capital gains are
determined in accordance with federal income tax regulations, which may differ
from U.S. GAAP. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These permanent differences are primarily due to the varying
treatment of income and gain/loss on portfolio securities held by the 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.


                                                                        Page 105

M. INCOME TAXES

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

The Funds are subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. For FIXD and UCON, the taxable
years ended 2018, 2019, 2020, and 2021 remain open to federal and state audit.
For DEED, the taxable years ended 2020 and 2021 remain open to federal and state
audit. For EFIX, the taxable year ended 2021 remains open to federal and state
audit. As of February 28, 2022, 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.

Each Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
Each Fund is subject to certain limitations under U.S. tax rules on the use of
capital loss carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At August 31, 2021, for
federal income tax purposes, each applicable Fund had a capital loss
carryforward available that is shown in the table below, to the extent provided
by regulations, to offset future capital gains. To the extent that these loss
carryforwards are used to offset future capital gains, it is probable that the
capital gains so offset will not be distributed to each applicable Fund's
shareholders.



                                                             Non-Expiring

N. EXPENSES

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

 3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS

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

TCW serves as the Funds' sub-advisor and manages each Fund's portfolio subject
to First Trust's supervision. Pursuant to the Investment Management Agreement,
between the Trust, on behalf of the Funds, and the Advisor, and the Investment
Sub-Advisory Agreement among the Trust, on behalf of the Funds, the Advisor and
TCW, First Trust will supervise TCW and its management of the investment of each
Fund's assets and will pay TCW for its services as the Funds' sub-advisor. TCW
receives a sub-advisory fee equal to 50% of any remaining monthly unitary
management fee paid to the Advisor after the average Fund's expenses accrued
during the most recent twelve months are subtracted from the unitary management
fee for that month. First Trust will also be responsible for each 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, if any, brokerage commissions and other expenses connected with
the execution of portfolio transactions, distribution and service fees payable
pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. FIXD, UCON,
DEED, and EFIX have each agreed to pay First Trust an annual unitary management
fee equal to 0.65%, 0.85%, 0.75%, and 0.95%, respectively, of its average daily
net assets. Pursuant to a contractual agreement, First Trust has agreed to waive
management fees of 0.10% of average daily net assets until December 31, 2022 for
FIXD, UCON and DEED and February 10, 2023 for EFIX. 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 each Fund or by the Funds' investment
advisor only after December 31, 2022 for FIXD, UCON and DEED and February 10,
2023 for EFIX. During the six months ended February 28, 2022, the Advisor waived
fees of $2,583,272, $400,430, $136,404, and $8,786, for FIXD, UCON, DEED, and
EFIX, respectively.

The Trust has multiple service agreements with The Bank of New York Mellon
("BNYM"). Under the service agreements, BNYM performs custodial, fund
accounting, certain administrative services, and transfer agency services for
each Fund. As custodian, BNYM is responsible for custody of each Fund's assets.
As fund accountant and administrator, BNYM is responsible for maintaining the
books and records of each Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for each Fund. BNYM is a
subsidiary of The Bank of New York Mellon Corporation, a financial holding
company.


                                                                        Page 107

                         FEBRUARY 28, 2022 (UNAUDITED)

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 Chairs of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro

                     FIRST TRUST EXCHANGE-TRADED FUND VIII
                         FEBRUARY 28, 2022 (UNAUDITED)


                 6. 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 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, 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.

                              7. DISTRIBUTION PLAN

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule
12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are
authorized to pay an amount up to 0.25% of their average daily net assets each
year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the
Funds, for amounts expended to finance activities primarily intended to result
in the sale of Creation Units or the provision of investor services. FTP may
also use this amount to compensate securities dealers or other persons that are
Authorized Participants for providing distribution assistance, including
broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before December 31, 2022 for
FIXD, UCON, and DEED and February 10, 2023 for EFIX.

                               8. 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.

                              9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Funds
through the date the financial statements were issued and has determined that
there were no subsequent events requiring recognition or disclosure in the
financial statements that have not already been disclosed.


                                                                        Page 111

                      PROXY VOTING POLICIES AND PROCEDURES

A description of the policies and procedures that the Trust uses to determine
how to vote proxies and information on how each Fund voted proxies relating to
its portfolio securities during the most recent 12-month period ended June 30 is
available (1) without charge, upon request, by calling (800) 988-5891; (2) on
each Fund's website at www.ftportfolios.com; and (3) on the Securities and
Exchange Commission's ("SEC") website at www.sec.gov.

                               PORTFOLIO HOLDINGS

Each Fund files portfolio holdings information for each month in a fiscal
quarter within 60 days after the end of the relevant fiscal quarter on Form
N-PORT. Portfolio holdings information for the third month of each fiscal
quarter will be publicly available on the SEC's website at www.sec.gov. Each
Fund's complete schedule of portfolio holdings for the second and fourth
quarters of each fiscal year is included in the semi-annual and annual reports
to shareholders, respectively, and is filed with the SEC on Form N-CSR. The
semi-annual and annual report for each Fund is available to investors within 60
days after the period to which it relates. Each Fund's Forms N-PORT and Forms
N-CSR are available on the SEC's website listed above.

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE
APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS
RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW
APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT
IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY
FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE,
RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF
ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT
WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO
REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND.

CONCENTRATION RISK. To the extent that a fund is able to invest a significant
percentage of its assets in a single asset class or the securities of issuers
within the same country, state, region, industry or sector, an adverse economic,
business or political development may affect the value of the fund's investments
more than if the fund were more broadly diversified. A fund that tracks an index
will be concentrated to the extent the fund's corresponding index is
concentrated. A concentration makes a fund more susceptible to any single
occurrence and may subject the fund to greater market risk than a fund that is
more broadly diversified.

CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable
or unwilling to make dividend, interest and/or principal payments when due and
the related risk that the value of a security may decline because of concerns
about the issuer's ability to make such payments.

CYBER SECURITY RISK. The funds are susceptible to potential operational risks
through breaches in cyber security. A breach in cyber security refers to both
intentional and unintentional events that may cause a fund to lose proprietary
information, suffer data corruption or lose operational capacity. Such events
could cause a fund to incur regulatory penalties, reputational damage,
additional compliance costs associated with corrective measures and/or financial
loss. In addition, cyber security breaches of a fund's third-party service
providers, such as its administrator, transfer agent, custodian, or sub-advisor,
as applicable, or issuers in which the fund invests, can also subject a fund to
many of the same risks associated with direct cyber security breaches.

DEFINED OUTCOME FUNDS RISK. To the extent a fund's investment strategy is
designed to deliver returns tied to the price performance of an underlying ETF,
an investor may not realize the returns the fund seeks to achieve if that
investor does not hold shares for the entire target outcome period. In the event
an investor purchases shares after the first day of the target outcome period or
sells shares prior to the end of the target outcome period, the buffer that the
fund seeks to provide against a decline in the value of the underlying ETF may
not be available, the enhanced returns that the fund seeks to provide (if any)
may not be available and the investor may not participate in a gain in the value
of the underlying ETF up to the cap for the investor's investment period.
Additionally, the fund will not participate in gains of the underlying ETF above
the cap and a shareholder may lose their entire investment. If the fund seeks
enhanced returns, there are certain time periods when the value of the fund may
fall faster than the value of the underlying ETF, and it is very unlikely that,
on any given day during which the underlying ETF share price increases in value,
the fund's share price will increase at the same rate as the enhanced returns
sought by the fund, which is designed for an entire target outcome period.
Trading flexible exchange options involves risks different from, or possibly
greater than, the risks associated with investing directly in securities, such
as less liquidity and correlation and valuation risks. A fund may experience
substantial downside from specific flexible exchange option positions and
certain positions may expire worthless.

                     FIRST TRUST EXCHANGE-TRADED FUND VIII
                         FEBRUARY 28, 2022 (UNAUDITED)

DERIVATIVES RISK. To the extent a fund uses derivative instruments such as
futures contracts, options contracts and swaps, the fund may experience losses
because of adverse movements in the price or value of the underlying asset,
index or rate, which may be magnified by certain features of the derivative.
These risks are heightened when a fund's portfolio managers use derivatives to
enhance the fund's return or as a substitute for a position or security, rather
than solely to hedge (or offset) the risk of a position or security held by the
fund.

EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the
value of the fund's shares will fluctuate with changes in the value of the
equity securities. Equity securities prices fluctuate for several reasons,
including changes in investors' perceptions of the financial condition of an
issuer or the general condition of the relevant stock market, such as market
volatility, or when political or economic events affecting the issuers occur. In
addition, common stock prices may be particularly sensitive to rising interest
rates, as the cost of capital rises and borrowing costs increase. Equity
securities may decline significantly in price over short or extended periods of
time, and such declines may occur in the equity market as a whole, or they may
occur in only a particular country, company, industry or sector of the market.

ETF RISK. The shares of an ETF trade like common stock and represent an interest
in a portfolio of securities. The risks of owning an ETF generally reflect the
risks of owning the underlying securities, although lack of liquidity in an ETF
could result in it being more volatile and ETFs have management fees that
increase their costs. Shares of an ETF trade on an exchange at market prices
rather than net asset value, which may cause the shares to trade at a price
greater than net asset value (premium) or less than net asset value (discount).
In times of market stress, decisions by market makers to reduce or step away
from their role of providing a market for an ETF's shares, or decisions by an
ETF's authorized participants that they are unable or unwilling to proceed with
creation and/or redemption orders of an ETF's shares, could result in shares of
the ETF trading at a discount to net asset value and in greater than normal
intraday bid-ask spreads.

FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income
securities, the fund will be subject to credit risk, income risk, interest rate
risk, liquidity risk and prepayment risk. Income risk is the risk that income
from a fund's fixed income investments could decline during periods of falling
interest rates. Interest rate risk is the risk that the value of a fund's fixed
income securities will decline because of rising interest rates. Liquidity risk
is the risk that a security cannot be purchased or sold at the time desired, or
cannot be purchased or sold without adversely affecting the price. Prepayment
risk is the risk that the securities will be redeemed or prepaid by the issuer,
resulting in lower interest payments received by the fund. In addition to these
risks, high yield securities, or "junk" bonds, are subject to greater market
fluctuations and risk of loss than securities with higher ratings, and the
market for high yield securities is generally smaller and less liquid than that
for investment grade securities.

INDEX OR MODEL CONSTITUENT RISK. Certain funds may be a constituent of one or
more indices or ETF models. As a result, such a fund may be included in one or
more index-tracking exchange-traded funds or mutual funds. Being a component
security of such a vehicle could greatly affect the trading activity involving a
fund, the size of the fund and the market volatility of the fund. Inclusion in
an index could increase demand for the fund and removal from an index could
result in outsized selling activity in a relatively short period of time. As a
result, a fund's net asset value could be negatively impacted and the fund's
market price may be significantly below its net asset value during certain
periods. In addition, index rebalances may potentially result in increased
trading activity in a fund's shares.

INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject
to Index Provider Risk. There is no assurance that the Index Provider will
compile the Index accurately, or that the Index will be determined, maintained,
constructed, reconstituted, rebalanced, composed, calculated or disseminated
accurately. To correct any such error, the Index Provider may carry out an
unscheduled rebalance or other modification of the Index constituents or
weightings, which may increase the fund's costs. The Index Provider does not
provide any representation or warranty in relation to the quality, accuracy or
completeness of data in the Index, and it does not guarantee that the Index will
be calculated in accordance with its stated methodology. Losses or costs
associated with any Index Provider errors generally will be borne by the fund
and its shareholders.

INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of
other investment vehicles, the fund will incur additional fees and expenses that
would not be present in a direct investment in those investment vehicles.
Furthermore, the fund's investment performance and risks are directly related to
the investment performance and risks of the investment vehicles in which the
fund invests.

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. The United Kingdom's Financial
Conduct Authority, which regulates LIBOR has ceased making LIBOR available as a
reference rate over a phase-out period that began December 31, 2021. There is no
assurance that any alternative reference rate, including the Secured Overnight
Financing Rate ("SOFR") will be similar to or produce the same value or economic
equivalence as LIBOR or that instruments using an alternative rate will have the
same volume or liquidity. The unavailability or replacement of LIBOR may affect
the value, liquidity or return on certain fund investments and may result in


                                                                        Page 113

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. In February 2022, Russia invaded Ukraine which has caused and could
continue to cause significant market disruptions and volatility within the
markets in Russia, Europe, and the United States. The hostilities and sanctions
resulting from those hostilities could have a significant impact on certain fund
investments as well as fund performance. The 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.
While the development of vaccines has slowed the spread of the virus and allowed
for the resumption of "reasonably" normal business activity in the United
States, many countries continue to impose lockdown measures in an attempt to
slow the spread. Additionally, there is no guarantee that vaccines will be
effective against emerging variants of the disease.

NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities,
it is subject to additional risks not associated with securities of domestic
issuers. Non-U.S. securities are subject to higher volatility than securities of
domestic issuers due to: possible adverse political, social or economic
developments; restrictions on foreign investment or exchange of securities;
capital controls; lack of liquidity; currency exchange rates; excessive
taxation; government seizure of assets; the imposition of sanctions by foreign
governments; different legal or accounting standards; and less government
supervision and regulation of exchanges in foreign countries. Investments in
non-U.S. securities may involve higher costs than investments in U.S.
securities, including higher transaction and custody costs, as well as
additional taxes imposed by non-U.S. governments. These risks may be heightened
for securities of companies located, or with significant operations, in emerging
market countries.

OPERATIONAL RISK. Each fund is subject to risks arising from various operational
factors, including, but not limited to, human error, processing and
communication errors, errors of a fund's service providers, counterparties or
other third-parties, failed or inadequate processes and technology or systems
failures. Each fund relies on third-parties for a range of services, including
custody. Any delay or failure relating to engaging or maintaining such service
providers may affect a fund's ability to meet its investment objective. Although
the funds and the funds' investment advisor seek to reduce these operational
risks through controls and procedures, there is no way to completely protect
against such risks.

PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund
will invest in the securities included in, or representative of, the index
regardless of their investment merit. A fund generally will not attempt to take
defensive positions in declining markets.
