SHAREHOLDER LETTER

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
ANNUAL LETTER FROM THE CHAIRMAN AND CEO
OCTOBER 31, 2022

Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Enhanced Short Maturity ETF (the "Fund"), which contains detailed information
about the Fund for the twelve months ended October 31, 2022.

As I'm writing this letter in mid-November, it strikes me that things appear to
be a little more chaotic in the current climate than normal. One of the things
that may have contributed to the chaotic nature of the news flow of late was the
November mid-term election. For the most part, except for a few seats in
Congress, the election is behind us. We learned there would be no "red wave"
(Republicans gaining a strong majority in Congress) but likely gridlock ahead.
Gridlock has been good for stock market investors in the past few decades,
particularly when there's been a Democratic president and the Republicans have
control of at least one house of Congress, according to Brian Wesbury, Chief
Economist at First Trust.

The Federal Reserve (the "Fed") has kept its promise to aggressively hike
interest rates to combat robust inflation. As of November 13, 2022, the Fed has
increased the Federal Funds target rate (upper bound) six times, from 0.25% to
4.00%. The Fed's actions have some investors and pundits looking for evidence
linking the interest rate hikes to a downturn in the economy. In short, the hope
is that a pullback in economic activity might deter the Fed from executing
further interest rate hikes. Fed Chairman Jerome Powell, however, recently said
that the terminal rate (the ultimate rate the Fed is targeting) will likely need
to be higher than previously estimated in order to curb stubbornly high
inflation. The Consumer Price Index ("CPI") is a commonly used measure of
inflation. The CPI stood at 7.7% on a trailing 12-month basis as of October 31,
2022, according to the U.S. Bureau of Labor Statistics. That is down from its
recent high of 9.1% in June 2022. Prior to this year, the last time the CPI was
higher than 7.0% was over 40 years ago. While monetary policy is an ongoing
process subject to change, the Fed does appear to be steadfast in its mission to
bring the rate of inflation back to its preferred level of 2.0%, and that will
take some time, in my opinion. Stay tuned!

Equity and fixed income markets have contended with numerous headwinds this
year, such as the war between Russia and Ukraine. Since setting its all-time
high of 4,796.56 on January 3, 2022, the S&P 500(R) Index has been in a bear
market (a price decline of 20% or more from the most recent high) for the better
part of 310 days. Suffice it to say, we are all looking forward to the end of
this bear market. With respect to corrections and bear markets, the silver
lining is that the S&P 500(R) Index has never failed to fully recover the losses
sustained in any previous downturn. Where might we see demand for stocks moving
forward? One such source could be stock buybacks. As of the last week of October
2022, U.S. companies had announced stock buybacks totaling $1 trillion so far
this year, according to Birinyi Associates. The fixed income market has not been
immune to selling pressure either. Year-to-date through November 10, 2022,
yields on the 10-Year Treasury Note increased by 258 basis points. As you may be
aware, bond yields and bond prices are inversely related, particularly with
respect to investment-grade bonds. As yields rise, prices fall and vice versa.
As noted above, the Fed has more work to do, so bond investors should not be
surprised to see interest rates and bond yields trend at least a bit higher in
the months ahead.

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

Sincerely,

/s/ James A. Bowen

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

FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)

The First Trust Enhanced Short Maturity ETF's (the "Fund") investment objective
is to seek current income, consistent with preservation of capital and daily
liquidity. Under normal market conditions, the Fund intends to achieve its
investment objective by investing at least 80% of its net assets in a portfolio
of U.S. dollar-denominated fixed- and variable-rate debt securities, including
securities issued or guaranteed by the U.S. government or its agencies,
instrumentalities or U.S. government-sponsored entities, residential and
commercial mortgage-backed securities, asset-backed securities, U.S. corporate
bonds, fixed income securities issued by non-U.S. corporations and governments,
municipal obligations, privately issued securities and other debt securities
bearing fixed or floating interest rates. The Fund may also invest in money
market securities. Shares of the Fund are listed on The Nasdaq Stock Market LLC
under the ticker symbol "FTSM."

The Fund's investment advisor, First Trust Advisors L.P. (the "Advisor"),
selects securities for the portfolio by evaluating fixed income sectors and
macro market trends while completing bottom-up analysis of individual
securities. Portfolio securities are selected based upon relative value in the
context of overall portfolio duration. Key inputs for the screens in the
securities selection process include, but are not limited to, credit quality,
yield, interest rate sensitivity and liquidity. The Fund's holdings are
systematically monitored for meaningful changes in performance and risk
measures. A security will generally be sold when the Advisor believes that a
security can be substituted for a similar investment that represents better
relative value; it lacks adequate compensation for embedded credit risk; or when
rebalancing the portfolio to maintain diversification. Under normal market
conditions, the Fund's average duration is expected to be less than one year and
the average maturity of the Fund's portfolio is expected to be less than three
years.

Total returns for the period since inception are calculated from the inception
date of the Fund. "Average Annual Total Returns" represent the average annual
change in value of an investment over the periods indicated. "Cumulative Total
Returns" represent the total change in value of an investment over the periods
indicated. The total returns would have been lower if certain fees had not been
waived and expenses reimbursed by the Advisor.

The Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint of the national best bid and offer price ("NBBO") as of
the time that the Fund's NAV is calculated. Under SEC rules, the NBBO consists
of the highest displayed buy and lowest sell prices among the various exchanges
trading the Fund at the time the Fund's NAV is calculated. Prior to January 1,
2019, the price used was the midpoint between the highest bid and the lowest
offer on the stock exchange on which shares of the Fund were listed for trading
as of the time that the Fund's NAV was calculated. Since shares of the Fund did
not trade in the secondary market until after 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 the Fund is used as a proxy for the secondary market
trading price to calculate market returns. NAV and market returns assume that
all distributions have been reinvested in the Fund at NAV and Market Price,
respectively.

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

(1) The ratings are by S&P Global Ratings. A credit rating is an assessment
provided by a nationally recognized statistical rating organization
(NRSRO) of the creditworthiness of an issuer with respect to debt
obligations. Ratings are measured highest to lowest on a scale that
generally ranges from AAA to D for long-term ratings and A-1+ to C for
short-term ratings. Investment grade is defined as those issuers that have
a long-term credit rating of BBB- or higher or a short-term credit rating
of A-3 or higher. The credit ratings shown relate to the credit worthiness
of the issuers of the underlying securities in the Fund, and not to the
Fund or its shares. U.S. Treasury and U.S. Agency mortgage-backed
securities appear under "Government." Credit ratings are subject to

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.

Performance in securitized product investment strategies can be impacted from
the benefits of purchasing odd lot positions. The impact of these investments
can be particularly meaningful when funds have limited assets under management
and may not be a sustainable source of performance as a fund grows in size.

PORTFOLIO COMMENTARY
--------------------------------------------------------------------------------

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
ANNUAL REPORT
OCTOBER 31, 2022 (UNAUDITED)

ADVISOR

First Trust Advisors L.P. ("First Trust") is the investment advisor to the First
Trust Enhanced Short Maturity ETF (the "Fund" or "FTSM"). In this capacity,
First Trust is responsible for the selection and ongoing monitoring of the
investments in the Fund's portfolio and certain other services necessary for the
management of the portfolio.

PORTFOLIO MANAGEMENT TEAM

TODD LARSON, CFA - SENIOR VICE PRESIDENT AND PORTFOLIO MANAGER
JEREMIAH CHARLES - SENIOR VICE PRESIDENT AND PORTFOLIO MANAGER
JAMES SNYDER - SENIOR VICE PRESIDENT AND PORTFOLIO MANAGER
ERIC R. MAISEL, CFA - SENIOR VICE PRESIDENT AND PORTFOLIO MANAGER

The portfolio managers are primarily and jointly responsible for the day-to-day
management of the Fund. Each portfolio manager has served as part of the
portfolio management team of the Fund since 2014, except for Eric R. Maisel who
has served as part of the portfolio management team of the Fund since 2015.

COMMENTARY

The Fund is an actively managed exchange-traded fund that seeks current income,
consistent with preservation of capital and daily liquidity.

MARKET RECAP

As the 12-month period ended October 31, 2022 got underway, financial markets
were responding to rising inflation that surprised the Federal Reserve (the
"Fed") and caused it to pivot abruptly and take a more hawkish stance toward the
path of monetary policy. At the December 2021 Federal Open Market Committee
("FOMC") meeting, the Fed shifted forward the timeline for rate hikes and backed
away from its view that inflation was "transitory."

The hawkish shift drove interest rates higher during the first quarter of 2022
as the market aggressively repriced the path of monetary policy. The prospect of
tighter financial conditions, in turn, set a negative framework for the
performance of risk assets. After hitting a record high the first week of 2022,
the S&P 500(R) Index trended steadily lower while credit spreads widened
materially. The Consumer Price Index ("CPI") continued to increase, validating
the Fed's pivot and the spike in commodity prices resulting from the outbreak of
war in Ukraine in late February 2022 only added fuel to the inflationary fire.

The second quarter saw a continuation of these market themes and a surprisingly
strong inflation reading in June 2022 pushed the Fed to hike the Federal Funds
target rate by 75 basis points ("bps") rather than the previously expected 50
bps. Reflecting tighter monetary policy, real rates, as measured by U.S.
Treasury TIPS yields, climbed steadily during the quarter and moved above 0.0%
after being deeply negative to start the year. Similarly, the amount of negative
yielding debt globally fell to $2 trillion from over $12 trillion. Bond funds
experienced a string of outflows in the wake of rising yields and negative
returns.

Because inflation continued to be elevated, there was no letup to rising yields
during the third quarter and into October 2022. Inflation remained stubbornly
high with the CPI printing 8.2% in September - the seventh consecutive month
over 8%. The FOMC continued to insist that bringing down inflation was its
primary objective, and rightly so. Even with stricter financial conditions, the
U.S. labor market showed little sign of weakness with nearly five million more
job vacancies than unemployed persons. So far in 2022, the Fed has raised the
Federal Funds target rate from 0.25% to 3.25% - including three hikes of 75 bps
at successive FOMC meetings. Despite the ongoing debate within financial markets
as to how far the Fed will push interest rate policy, Fed Chairman Jerome Powell
made the Fed's position abundantly clear in a speech at the Fed's Jackson Hole
Symposium in late August 2022. He noted that "the historical record cautions
strongly against prematurely loosening policy," despite the pain that may be
felt by households and businesses.

For the 12-month period ending October 31, 2022, the 10-Year Treasury yield
increased 252 bps to 4.07%, the 2-Year Treasury yield increased 401 bps to
4.50%, and the 1-Year Treasury yield increased 450 bps to 4.62%. Commercial
paper yields also moved higher on the back of rate hikes by the Fed. The average
yield on 90-day Tier 1 commercial paper ended the third quarter of 2022 at 4.4%,
up 430 bps from a year ago. The impact of rising yields was felt across the
market with the S&P 500(R) Index and the Bloomberg U.S. Aggregate Bond Index
posting 12-month returns of -14.61% and -15.68%, respectively.

PORTFOLIO COMMENTARY (CONTINUED)
--------------------------------------------------------------------------------

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
ANNUAL REPORT
OCTOBER 31, 2022 (UNAUDITED)

PERFORMANCE ANALYSIS

The Fund's net asset value ("NAV") and market price performance were 0.08% and
0.11%, respectively for the 12-month period ended October 31, 2022, versus the
ICE BofA 0-1 Year U.S. Treasury Index's (the "Benchmark") return of -0.06%.

The Fund's defensive duration positioning was the key driver of outperformance
relative to the Benchmark. In a period of rapidly rising interest rates, the
impact of rising rates on Fund performance was mitigated by maintaining a low
duration posture through a large allocation to cash equivalents and
floating-rate securities. The allocations to commercial paper, floating-rate
corporate bonds, Treasury securities, and Non-Agency Commercial Mortgage-Backed
Securities were the leading sources of outperformance. The allocation to
fixed-rate corporate bonds, asset-backed securities, and collateralized mortgage
obligations were the main detractors. Within corporate credit, industries
delivering the best results were communications, energy, and electric utilities
while consumer non-cyclical, technology, and basics were the leading detractors.
From a rating quality perspective, BBB-rated bonds delivered slightly better
returns compared to those with an A rating due to better contribution from
credit spreads.

Throughout the reporting period the Fund maintained a diversified allocation
with an emphasis on securities having a high level of liquidity. Overall credit
risk was kept low as the investment strategy focused on high quality, short-term
holdings. The Fund's weighted average maturity was kept around eight months and
effective duration approximately five months. By maintaining a low duration and
low average maturity, the strategy successfully achieved its objective of
seeking current income. By capturing rising interest rates, the Fund was able to
raise its distribution rate during the period from an annualized rate of 0.28%
to 2.77%.

MARKET AND FUND OUTLOOK

In this environment, our preference is to maintain low interest rate exposure
and capture yield with floating-rate securities, cash equivalents, and
short-maturity fixed rate bonds. As the Fed focuses on raising its target policy
rate to combat sustained inflation, bond investors, in our view, should avoid
fighting the Fed. In our opinion, higher rates will ultimately result in demand
destruction and eventually lower inflationary pressures. However, given how
monetary policy operates with a lag, the impact from both recent and future
hikes remains unknown, in our view. Our market framework centers on the Fed
staying the course, raising the policy rate to 4.5%-5.0%, then holding rates at
a restrictive level. Given the Fed's focus on inflation and employment, both of
which are lagging economic indicators, recession risk in 2023 remains
significantly elevated, in our opinion. With the volatility in rates likely to
continue, we believe extending duration is not yet warranted, but that time will
likely come midway through next year. Valuations in short-maturity corporate
bonds remain attractive, as market yields continue to exceed durations and
all-in yields are well above average over the prior two decades. Additionally,
we continue to favor credits in defensive sectors, including healthcare,
software, and regulated utilities. Our focus is on high quality issuers with
proven business models and durable cash flows.

We expect curve allocation to be an important component of total return in the
year ahead, as well as security selection, sector allocation and the yield
advantage the Fund enjoys above its Benchmark. Strategic positioning across the
yield curve and among market sectors will complement rigorous credit
underwriting that goes into in the security selection process.

We expect the Fund will maintain its duration underweight relative to its
Benchmark, at least over the near term, while keeping corporate credit (both
commercial paper and corporate bonds) as the largest exposure. The Fund will
also seek to maintain its allocation to securitized debt (asset-backed
securities/mortgage-backed securities) for diversification purposes and where
valuations represent compelling opportunities relative to U.S. Treasuries and
corporate credit. As always, the focus will be in the senior part of the capital
structure.

As we evaluate new investment opportunities, our research will seek to identify
opportunities that we believe offer the best risk/reward balance, and decisions
will continue to be based on the analysis of data that results in sound,
evidence-based conclusions. We believe the Fund is well positioned to add value
relative compared to its Benchmark.

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2022 (UNAUDITED)

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended October 31, 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 the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

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

(a) Floating or variable rate security.

(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. 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 October 31, 2022, securities noted as such
amounted to $577,851,004 or 8.4% of net assets.

(c) Fixed-to-floating or fixed-to-variable rate security. The interest rate
shown reflects the fixed rate in effect at October 31, 2022. At a
predetermined date, the fixed rate will change to a floating rate or a
variable rate.

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

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

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022

1. ORGANIZATION

First Trust Exchange-Traded Fund IV (the "Trust") is an open-end management
investment company organized as a Massachusetts business trust on September 15,
2010, and is registered with the Securities and Exchange Commission ("SEC")
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twelve funds that are offering shares. This
report covers the First Trust Enhanced Short Maturity ETF (the "Fund"), a
diversified series of the Trust, which trades under the ticker "FTSM" on The
Nasdaq Stock Market LLC ("Nasdaq"). The Fund represents a separate series of
shares of beneficial interest in the Trust. Unlike conventional mutual funds,
the Fund issues and redeems shares on a continuous basis, at net asset value
("NAV"), only in large blocks of shares known as "Creation Units."

The Fund is an actively managed exchange-traded fund ("ETF"). The Fund's
investment objective is to seek current income, consistent with preservation of
capital and daily liquidity. Under normal market conditions, the Fund intends to
achieve its investment objective by investing at least 80% of its net assets in
a portfolio of U.S. dollar-denominated fixed- and variable-rate debt securities,
including securities issued or guaranteed by the U.S. government or its
agencies, instrumentalities or U.S. government-sponsored entities, residential
and commercial mortgage-backed securities, asset-backed securities, U.S.
corporate bonds, fixed income securities issued by non-U.S. corporations and
governments, municipal obligations, privately issued securities and other debt
securities bearing fixed or floating interest rates. The Fund may also invest in
money market securities. The Fund may invest in investment companies, such as
ETFs, that invest primarily in debt securities. The Fund intends to limit its
investments in privately-issued, non-agency sponsored mortgage- and asset-backed
securities to 20% of its net assets. The Fund may also invest up to 20% of its
net assets in floating rate loans representing amounts borrowed by companies or
other entities from banks and other lenders. A significant portion of these
loans may be rated below investment grade or unrated. Floating rate loans held
by the Fund may be senior or subordinate obligations of the borrower and may or
may not be secured by collateral. Under normal market conditions, the Fund's
average duration is expected to be less than one year and the average maturity
of the Fund's portfolio is expected to be less than three years. There can be no
assurance that the Fund will achieve its investment objective. The Fund may not
be appropriate for all investors.

2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

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

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent readily available market quotations such as last sale or
official closing prices from a national or foreign exchange (i.e., a regulated
market) and are primarily obtained from third-party pricing services. Fair value
prices represent any prices not considered market value prices and are either
obtained from a third-party pricing service or are determined by the Pricing
Committee of the Fund's investment advisor, First Trust Advisors L.P. ("First
Trust" or the "Advisor"), in accordance with valuation procedures approved by
the Trust's Board of Trustees, and in accordance with provisions of the 1940 Act
and rules thereunder. Investments valued by the Advisor's Pricing Committee, if
any, are footnoted as such in the footnotes to the Portfolio of Investments. The
Fund's investments are valued as follows:

Corporate bonds, corporate notes, U.S. government securities,
mortgage-backed securities, asset-backed securities, certificates of
deposit 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 Advisor's Pricing Committee,
which may use the following valuation inputs when available:

1) benchmark yields;
2) reported trades;
3) broker/dealer quotes;

4) issuer spreads;
5) benchmark securities;
6) bids and offers; and
7) reference data including market research publications.

Pricing services generally value fixed-income securities assuming orderly
transactions of an institutional round lot size, but a Fund may hold or
transact in such securities in smaller, odd lot sizes. Odd lots may trade
at lower prices than institutional round lots.

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

Commercial paper is 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.

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 fair 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.

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

1) the most recent price provided by a pricing service;
2) the fundamental business data relating to the borrower/issuer;
3) an evaluation of the forces which influence the market in
which these securities are purchased and sold;
4) the type, size and cost of a security;
5) the financial statements of the borrower/issuer or the
financial condition of the country of issue;
6) the credit quality and cash flow of the borrower/issuer, or
country of issue, based on the Pricing Committee's,
sub-adviser's or portfolio manager's analysis, as applicable,
or external analysis;
7) the information as to any transactions in or offers for the
security;

-----------------------------

(1) The terms "security" and "securities" used throughout the Notes to
Financial Statements include Senior Loans.

Page 32

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022

8) the price and extent of public trading in similar securities
of the borrower/issuer, or comparable companies;
9) the coupon payments;
10) the quality, value and salability of collateral, if any,
securing the security;
11) the business prospects of the borrower/issuer, including any
ability to obtain money or resources from a parent or
affiliate and an assessment of the borrower's/issuer's
management (for corporate debt only);
12) the prospects for the borrower's/issuer's industry, and
multiples (of earnings and/or cash flows) being paid for
similar businesses in that industry (for corporate debt only);
13) the borrower's/issuer's competitive position within the
industry;
14) the borrower's/issuer's ability to access additional liquidity
through public and/or private markets; and
15) other relevant factors.

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

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 the Fund's investments as of October 31, 2022, is
included with the Fund's Portfolio of Investments.

In December 2020, the SEC adopted Rule 2a-5 under the 1940 Act, establishing
requirements to determine fair value in good faith for purposes of the 1940 Act.
The rule permits fund boards to designate a fund's investment adviser to perform
fair value determinations, subject to board oversight and certain other
conditions. The rule also defines when market quotations are "readily available"
for purposes of the 1940 Act and requires a fund to fair value a portfolio
investment when a market quotation is not readily available. The SEC also
adopted new Rule 31a-4 under the 1940 Act, which sets forth recordkeeping
requirements associated with fair value determinations. The compliance date for
Rule 2a-5 and Rule 31a-4 was September 8, 2022.

Effective September 8, 2022 and pursuant to the requirements of Rule 2a-5, the
Trust's Board of Trustees designated the Advisor as its valuation designee to
perform fair value determinations and approved new Advisor Valuation Procedures
for the Trust.

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.

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 Fund or
its investments.

C. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income, if any, are declared and paid monthly by
the Fund, or as the Board of Trustees may determine from time to time.
Distributions of net realized gains earned by the Fund, if any, are distributed
at least annually. The Fund may also designate a portion of the amount paid to
redeeming shareholders as a distribution for tax purposes.

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 Fund and
have no impact on net assets or NAV per share. Temporary differences, which
arise from recognizing certain items of income, expense and gain/loss in
different periods for financial statement and tax purposes, will reverse at some
time in the future.

The tax character of distributions paid during the fiscal years ended October
31, 2022 and 2021 was as follows:

Distributions paid from: 2022 2021
Ordinary income................................. $ 46,350,806 $ 23,640,819
Capital gains................................... -- --
Return of capital............................... -- --
As of October 31, 2022, the components of distributable earnings on a tax basis
for the Fund were as follows:

Undistributed ordinary income................... $ 322,904
Accumulated capital and other gain (loss)....... (12,864,893)
Net unrealized appreciation (depreciation)...... (47,392,590)

D. INCOME TAXES

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

The Fund is subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. The taxable years ended 2019,
2020, 2021, and 2022 remain open to federal and state audit. As of October 31,
2022, management has evaluated the application of these standards to the Fund
and has determined that no provision for income tax is required in the Fund's
financial statements for uncertain tax positions.

The Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
The Fund is subject to certain limitations under U.S. tax rules on the use of
capital loss carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At October 31, 2022, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $12,864,893.

Page 34

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022

Certain losses realized during the current fiscal year may be deferred and
treated as occurring on the first day of the following fiscal year for federal
income tax purposes. For the fiscal year ended October 31, 2022, the Fund had no
net late year ordinary or capital losses.

In order to present paid-in capital and accumulated distributable earnings
(loss) (which consists of accumulated net investment income (loss), accumulated
net realized gain (loss) on investments and net unrealized appreciation
(depreciation) on investments) on the Statement of Assets and Liabilities that
more closely represent their tax character, certain adjustments have been made
to paid-in capital, accumulated net investment income (loss) and accumulated net
realized gain (loss) on investments. These adjustments are primarily due to the
difference between book and tax treatments of income and gains on various
investment securities held by the Fund. The results of operations and net assets
were not affected by these adjustments. For the fiscal year ended October 31,
2022, there were no tax adjustments made to accumulated distributable earnings
(loss) accounts due to differences between book and tax treatments.

As of October 31, 2022, the aggregate cost, gross unrealized appreciation, gross
unrealized depreciation, and net unrealized appreciation/(depreciation) on
investments (including short positions and derivatives, if any) for federal
income tax purposes were as follows:

Gross Gross Net Unrealized
Unrealized Unrealized Appreciation
Tax Cost Appreciation (Depreciation) (Depreciation)
-------------- -------------- --------------- ---------------

$7,018,110,601 $ 82,151 $ (47,474,741) $ (47,392,590)

E. EXPENSES

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

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

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

Pursuant to the Investment Management Agreement between the Trust and Advisor,
First Trust manages the investment of the Fund's assets and is responsible for
the Fund's expenses, including the cost of transfer agency, custody, fund
administration, legal, audit and other services, but excluding fee payments
under the Investment Management Agreement, interest, taxes, acquired fund fees
and expenses with the exception of those attributable to affiliated funds,
brokerage commissions and other expenses connected with the execution of
portfolio transactions, distribution and service fees pursuant to a Rule 12b-1
plan, if any, and extraordinary expenses.

The Fund has agreed to pay First Trust an annual unitary management fee equal to
0.45% of its average daily net assets. Pursuant to two separate contractual
agreements, First Trust has agreed to waive management fees of 0.20% of average
daily net assets until March 1, 2023. At that point, the waiver agreement will
expire and will not be renewed. Pursuant to a contractual agreement between the
Trust, on behalf of the Fund, and First Trust, the management fees paid to First
Trust will be reduced by the portion of the management fees earned by First
Trust from the Fund for assets invested in other investment companies advised by
First Trust. This contractual agreement shall continue until the earlier of (i)
its termination at the direction of the Trust's Board of Trustees or (ii) upon
termination of the Fund's management agreement with First Trust; however, it is
expected to remain in place at least until March 1, 2023. First Trust does not
have the right to recover the fees waived that are attributable to the assets
invested in other investment companies advised by First Trust. During the fiscal
year ended October 31, 2022, the Advisor waived fees of $9,695,795.

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
the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As
fund accountant and administrator, BNYM is responsible for maintaining the books
and records of the Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for the Fund. BNYM is a
subsidiary of The Bank of New York Mellon Corporation, a financial holding
company.

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Each Independent Trustee is also paid an annual per fund fee that
varies based on whether the fund is a closed-end or other actively managed fund,
a target outcome fund, or an index fund.

Additionally, the Lead Independent Trustee and the Chairs of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
Independent Trustees are reimbursed for travel and out-of-pocket expenses in
connection with all meetings. The Lead Independent Trustee and Committee Chairs
will rotate every three years. The officers and "Interested" Trustee receive no
compensation from the Trust for acting in such capacities.

4. PURCHASES AND SALES OF SECURITIES

The costs of purchases of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments, for the fiscal year ended October
31, 2022, were $198,532,808 and $1,099,547,043, respectively. The proceeds from
sales and paydowns of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments, for the fiscal year ended October
31, 2022 were $34,517,440 and $1,757,484,335, respectively.

For the fiscal year ended October 31, 2022, the Fund had no in-kind
transactions.

5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

The Fund generally issues and redeems its shares in primary market transactions
through a creation and redemption mechanism and does not sell or redeem
individual shares. Instead, financial entities known as "Authorized
Participants" have contractual arrangements with the Fund's service providers to
purchase and redeem Fund shares directly with the Fund in large blocks of shares
known as "Creation Units." Prior to the start of trading on every business day,
the Fund publishes through the National Securities Clearing Corporation ("NSCC")
the "basket" of securities, cash or other assets that it will accept in exchange
for a Creation Unit of the Fund's shares. An Authorized Participant that wishes
to effectuate a creation of the Fund's shares deposits with the Fund the
"basket" of securities, cash or other assets identified by the Fund that day,
and then receives the Creation Unit of the Fund's shares in return for those
assets. After purchasing a Creation Unit, the Authorized Participant may
continue to hold the Fund's shares or sell them in the secondary market. The
redemption process is the reverse of the purchase process: the Authorized
Participant redeems a Creation Unit of the Fund's shares for a basket of
securities, cash or other assets. The combination of the creation and redemption
process with secondary market trading in the Fund's shares and underlying
securities provides arbitrage opportunities that are designed to help keep the
market price of the Fund's shares at or close to the NAV per share of the Fund.

The Fund imposes fees in connection with the purchase of Creation Units. These
fees may vary based upon various fact-based circumstances, including, but not
limited to, the composition of the securities included in the Creation Unit or
the countries in which the transactions are settled. The price for each Creation
Unit will equal the daily NAV per share of the Fund times the number of shares
in a Creation Unit, plus the fees described above and, if applicable, any
operational processing and brokerage costs, transfer fees, stamp taxes and part
or all of the spread between the expected bid and offer side of the market
related to the securities comprising the creation basket.

The Fund also imposes fees in connection with the redemption of Creation Units.
These fees may vary based upon various fact-based circumstances, including, but
not limited to, the composition of the securities included in the Creation Unit
or the countries in which the transactions are settled. The price received for
each Creation Unit will equal the daily NAV per share of the Fund times the
number of shares in a Creation Unit, minus the fees described above and, if
applicable, any operational processing and brokerage costs, transfer fees, stamp
taxes and part or all of the spread between the expected bid and offer side of
the market related to the securities comprising the redemption basket. Investors
who use the services of a broker or other such intermediary in addition to an
Authorized Participant to effect a redemption of a Creation Unit may also be
assessed an amount to cover the cost of such services. The redemption fee
charged by the Fund will comply with Rule 22c-2 of the 1940 Act which limits
redemption fees to no more than 2% of the value of the shares redeemed.

6. DISTRIBUTION PLAN

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

Page 36

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022

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 Fund, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before March 31, 2024.

7. INDEMNIFICATION

The Trust, on behalf of the Fund, has a variety of indemnification obligations
under contracts with its service providers. The Trust's maximum exposure under
these arrangements is unknown. However, the Trust has not had prior claims or
losses pursuant to these contracts and expects the risk of loss to be remote.

8. SUBSEQUENT EVENTS

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

At a meeting on October 24, 2022, the Board of Trustees approved a breakpoint
pricing arrangement for each of the series of the Trust, including the Fund.
Pursuant to this arrangement, which is effective as of November 1, 2022, the
management fee the Fund pays to First Trust, as investment manager, will be
discounted as the Fund's net assets reach certain predefined levels.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

TO THE SHAREHOLDERS AND THE BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
FUND IV:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statement of assets and liabilities of First
Trust Enhanced Short Maturity ETF (the "Fund"), a series of the First Trust
Exchange-Traded Fund IV, including the portfolio of investments, as of October
31, 2022, the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, the financial highlights for each of the five years in the period then
ended, and the related notes. In our opinion, the financial statements and
financial highlights present fairly, in all material respects, the financial
position of the Fund as of October 31, 2022, and the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the period then ended in conformity with accounting principles
generally accepted in the United States of America.

BASIS FOR OPINION

These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on the Fund's
financial statements and financial highlights based on our audits. We are a
public accounting firm registered with the Public Company Accounting Oversight
Board (United States) (PCAOB) and are required to be independent with respect to
the Fund in accordance with the U.S. federal securities laws and the applicable
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement, whether due to error or fraud. The Fund is not
required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting. As part of our audits we are required to
obtain an understanding of internal control over financial reporting but not for
the purpose of expressing an opinion on the effectiveness of the Fund's internal
control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material
misstatement of the financial statements and financial highlights, whether due
to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the financial statements and financial highlights. Our audits
also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of October 31, 2022, by correspondence with
the custodian and brokers; when replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

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

Page 39

--------------------------------------------------------------------------------

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022 (UNAUDITED)

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.

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.

OCTOBER 31, 2022 (UNAUDITED)

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
costs incurred in connection with closing out positions and entering into new
trades. Any potential effects of the transition away from LIBOR on the fund or
on certain instruments in which the fund invests can be difficult to ascertain,
and they may vary depending on a variety of factors, and they could result in
losses to the fund.

MANAGEMENT RISK. To the extent that a fund is actively managed, it is subject to
management risk. In managing an actively-managed fund's investment portfolio,
the fund's portfolio managers will apply investment techniques and risk analyses
that may not have the desired result. There can be no guarantee that a fund will
meet its investment objective.

MARKET RISK. Market risk is the risk that a particular security, or shares of a
fund in general, may fall in value. Securities held by a fund, as well as shares
of a fund itself, are subject to market fluctuations caused by factors such as
general economic conditions, political events, regulatory or market
developments, changes in interest rates and perceived trends in securities
prices. Shares of a fund could decline in value or underperform other
investments as a result of the risk of loss associated with these market
fluctuations. In addition, local, regional or global events such as war, acts of
terrorism, spread of infectious diseases or other public health issues,
recessions, or other events could have a significant negative impact on a fund
and its investments. Such events may affect certain geographic regions,
countries, sectors and industries more significantly than others. In February
2022, Russia invaded Ukraine which has caused and could continue to cause
significant market disruptions and volatility within the markets in Russia,
Europe, and the United States. The hostilities and sanctions resulting from
those hostilities could have a significant impact on certain fund investments as
well as fund performance. The COVID-19 global pandemic and the ensuing policies
enacted by governments and central banks have caused and may continue to cause
significant volatility and uncertainty in global financial markets. While the
U.S. has resumed "reasonably" normal business activity, many countries continue
to impose lockdown measures. Additionally, there is no guarantee that vaccines
will be effective against emerging variants of the disease. These events also
adversely affect the prices and liquidity of a fund's portfolio securities or
other instruments and could result in disruptions in the trading markets. Any of
such circumstances could have a materially negative impact on the value of a
fund's shares and result in increased market volatility. During any such events,
a fund's shares may trade at increased premiums or discounts to their net asset
value and the bid/ask spread on a fund's shares may widen.

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

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

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

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022 (UNAUDITED)

PREFERRED SECURITIES RISK. Preferred securities combine some of the
characteristics of both common stocks and bonds. Preferred securities are
typically subordinated to bonds and other debt securities in a company's capital
structure in terms of priority to corporate income, subjecting them to greater
credit risk than those debt securities. Generally, holders of preferred
securities have no voting rights with respect to the issuing company unless
preferred dividends have been in arrears for a specified number of periods, at
which time the preferred security holders may obtain limited rights. In certain
circumstances, an issuer of preferred securities may defer payment on the
securities and, in some cases, redeem the securities prior to a specified date.
Preferred securities may also be substantially less liquid than other
securities, including common stock.

VALUATION RISK. The valuation of certain securities may carry more risk than
that of common stock. Uncertainties in the conditions of the financial markets,
unreliable reference data, lack of transparency and inconsistency of valuation
models and processes may lead to inaccurate asset pricing. A fund may hold
investments in sizes smaller than institutionally sized round lot positions
(sometimes referred to as odd lots). However, third-party pricing services
generally provide evaluations on the basis of institutionally-sized round lots.
If a fund sells certain of its investments in an odd lot transaction, the sale
price may be less than the value at which such securities have been held by the
fund. Odd lots often trade at lower prices than institutional round lots. There
is no assurance that the fund will be able to sell a portfolio security at the
price established by the pricing service, which could result in a loss to the
fund.

ADVISORY AGREEMENT

BOARD CONSIDERATIONS REGARDING APPROVAL OF CONTINUATION OF INVESTMENT MANAGEMENT
AGREEMENT

The Board of Trustees of First Trust Exchange-Traded Fund IV (the "Trust"),
including the Independent Trustees, unanimously approved the continuation of the
Investment Management Agreement (the "Agreement") with First Trust Advisors L.P.
(the "Advisor") on behalf of the First Trust Enhanced Short Maturity ETF (the
"Fund"). The Board approved the continuation of the Agreement for a one-year
period ending June 30, 2023 at a meeting held on June 12-13, 2022. The Board
determined that the continuation of the Agreement is in the best interests of
the Fund in light of the nature, extent and quality of the services provided and
such other matters as the Board considered to be relevant in the exercise of its
business judgment.

To reach this determination, the Board considered its duties under the
Investment Company Act of 1940, as amended (the "1940 Act"), as well as under
the general principles of state law, in reviewing and approving advisory
contracts; the requirements of the 1940 Act in such matters; the fiduciary duty
of investment advisors with respect to advisory agreements and compensation; the
standards used by courts in determining whether investment company boards have
fulfilled their duties; and the factors to be considered by the Board in voting
on such agreements. At meetings held on April 18, 2022 and June 12-13, 2022, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor responding to requests for information from counsel to the Independent
Trustees, submitted on behalf of the Independent Trustees, that, among other
things, outlined: the services provided by the Advisor to the Fund (including
the relevant personnel responsible for these services and their experience); the
unitary fee rate payable by the Fund as compared to fees charged to a peer group
of funds (the "Expense Group") and a broad peer universe of funds (the "Expense
Universe"), each assembled by Broadridge Financial Solutions, Inc.
("Broadridge"), an independent source, and as compared to fees charged to other
clients of the Advisor, including other exchange-traded funds ("ETFs") managed
by the Advisor; the expense ratio of the Fund as compared to expense ratios of
the funds in the Fund's Expense Group and Expense Universe; performance
information for the Fund, including comparisons of the Fund's performance to
that of one or more relevant benchmark indexes and to that of a performance
group of funds and a broad performance universe of funds (the "Performance
Universe"), each assembled by Broadridge; the nature of expenses incurred in
providing services to the Fund and the potential for the Advisor to realize
economies of scale, if any; profitability and other financial data for the
Advisor; any indirect benefits to the Advisor and its affiliate, First Trust
Portfolios L.P. ("FTP"); and information on the Advisor's compliance program.
The Board reviewed initial materials with the Advisor at the meeting held on
April 18, 2022, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the
April meeting, counsel to the Independent Trustees, on behalf of the Independent
Trustees, requested certain clarifications and supplements to the materials
provided, and the information provided in response to those requests was
considered at an executive session of the Independent Trustees and their counsel
held prior to the June 12-13, 2022 meeting, as well as at the June meeting. The
Board applied its business judgment to determine whether the arrangement between
the Trust and the Advisor continues to be a reasonable business arrangement from
the Fund's perspective. The Board determined that, given the totality of the
information provided with respect to the Agreement, the Board had received
sufficient information to renew the Agreement. The Board considered that
shareholders chose to invest or remain invested in the Fund knowing that the
Advisor manages the Fund and knowing the Fund's unitary fee.

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022 (UNAUDITED)

In reviewing the Agreement, the Board considered the nature, extent and quality
of the services provided by the Advisor under the Agreement. The Board
considered that the Advisor is responsible for the overall management and
administration of the Trust and the Fund and reviewed all of the services
provided by the Advisor to the Fund, as well as the background and experience of
the persons responsible for such services. The Board noted that the Fund is an
actively-managed ETF and considered the background and experience of the persons
responsible for the day-to-day management of the Fund's investments. In
reviewing the services provided, the Board noted the compliance program that had
been developed by the Advisor and considered that it includes a robust program
for monitoring the Advisor's and the Fund's compliance with the 1940 Act, as
well as the Fund's compliance with its investment objective, policies and
restrictions. The Board also considered a report from the Advisor with respect
to its risk management functions related to the operation of the Fund. Finally,
as part of the Board's consideration of the Advisor's services, the Advisor, in
its written materials and at the April 18, 2022 meeting, described to the Board
the scope of its ongoing investment in additional personnel and infrastructure
to maintain and improve the quality of services provided to the Fund and the
other funds in the First Trust Fund Complex. In light of the information
presented and the considerations made, the Board concluded that the nature,
extent and quality of the services provided to the Trust and the Fund by the
Advisor under the Agreement have been and are expected to remain satisfactory
and that the Advisor has managed the Fund consistent with its investment
objective, policies and restrictions.

The Board considered the unitary fee rate payable by the Fund under the
Agreement for the services provided. The Board considered that as part of the
unitary fee the Advisor is responsible for the Fund's expenses, including the
cost of transfer agency, custody, fund administration, legal, audit and other
services and license fees, if any, but excluding the fee payment under the
Agreement and interest, taxes, acquired fund fees and expenses, brokerage
commissions and other expenses connected with the execution of portfolio
transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if
any, and extraordinary expenses, if any. The Board noted that the Advisor had
previously agreed to waive a portion of its unitary fee in an aggregate amount
equal to 0.20% of the Fund's average daily net assets until at least March 1,
2023 and also to reduce the unitary fee to the extent of acquired fund fees and
expenses of shares of investment companies advised by the Advisor that are held
by the Fund. The Board received and reviewed information showing the fee rates
and expense ratios of the peer funds in the Expense Group, as well as advisory
and unitary fee rates charged by the Advisor to other fund (including ETFs) and
non-fund clients, as applicable. Because the Fund pays a unitary fee, the Board
determined that expense ratios were the most relevant comparative data point.
Based on the information provided, the Board noted that the unitary fee rate for
the Fund, after taking into account the contractual fee waivers, was below the
median total (net) expense ratio of the peer funds in the Expense Group. With
respect to the Expense Group, the Board, at the April 18, 2022 meeting,
discussed with Broadridge its methodology for assembling peer groups and
discussed with the Advisor limitations in creating peer groups for
actively-managed ETFs and different business models that may affect the pricing
of services among ETF sponsors. The Board took these limitations and differences
into account in considering the peer data. With respect to fees charged to other
non-ETF clients, the Board considered differences between the Fund and other
non-ETF clients that limited their comparability. In considering the unitary fee
rate overall, the Board also considered the Advisor's statement that it seeks to
meet investor needs through innovative and value-added investment solutions and
the Advisor's demonstrated long-term commitment to the Fund and the other funds
in the First Trust Fund Complex.

The Board considered performance information for the Fund. The Board noted the
process it has established for monitoring the Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor for the Fund. The Board determined that this process continues to be
effective for reviewing the Fund's performance. The Board received and reviewed
information comparing the Fund's performance for periods ended December 31, 2021
to the performance of the funds in the Performance Universe and to that of a
benchmark index. Based on the information provided, the Board noted that the
Fund outperformed the Performance Universe median and underperformed the
benchmark index for the one-year period ended December 31, 2021 and
underperformed the Performance Universe median and outperformed the benchmark
index for the three- and five-year periods ended December 31, 2021.

On the basis of all the information provided on the unitary fee and performance
of the Fund and the ongoing oversight by the Board, the Board concluded that the
unitary fee for the Fund continues to be reasonable and appropriate in light of
the nature, extent and quality of the services provided by the Advisor to the
Fund under the Agreement.

The Board considered information and discussed with the Advisor whether there
were any economies of scale in connection with providing advisory services to
the Fund and noted the Advisor's statement that it believes that its expenses
relating to providing advisory services to the Fund will likely increase during
the next twelve months as the Advisor continues to build infrastructure and add
new staff. The Board noted that any reduction in fixed costs associated with the
management of the Fund would benefit the Advisor, but that the unitary fee
structure provides a level of certainty in expenses for the Fund. The Board

Page 43

--------------------------------------------------------------------------------
ADDITIONAL INFORMATION (CONTINUED)
--------------------------------------------------------------------------------

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022 (UNAUDITED)

considered the revenues and allocated costs (including the allocation
methodology) of the Advisor in serving as investment advisor to the Fund for the
twelve months ended December 31, 2021 and the estimated profitability level for
the Fund calculated by the Advisor based on such data, as well as complex-wide
and product-line profitability data, for the same period. The Board noted the
inherent limitations in the profitability analysis and concluded that, based on
the information provided, the Advisor's profitability level for the Fund was not
unreasonable. In addition, the Board considered indirect benefits described by
the Advisor that may be realized from its relationship with the Fund. The Board
considered that the Advisor had identified as an indirect benefit to the Advisor
and FTP their exposure to investors and brokers who, absent their exposure to
the Fund, may have had no dealings with the Advisor or FTP, and noted that the
Advisor does not utilize soft dollars in connection with the Fund. The Board
concluded that the character and amount of potential indirect benefits to the
Advisor were not unreasonable.

Based on all of the information considered and the conclusions reached, the
Board, including the Independent Trustees, unanimously determined that the terms
of the Agreement continue to be fair and reasonable and that the continuation of
the Agreement is in the best interests of the Fund. No single factor was
determinative in the Board's analysis.

BOARD CONSIDERATIONS REGARDING APPROVAL OF AMENDMENTS TO THE INVESTMENT
MANAGEMENT AGREEMENT

The Board of Trustees of First Trust Exchange-Traded Fund IV (the "Trust"),
including the Independent Trustees, unanimously approved the amendment (the
"Amendment") of the Investment Management Agreement (the "Agreement") with First
Trust Advisors L.P. (the "Advisor") on behalf of the First Trust Enhanced Short
Maturity ETF (the "Fund").

The Board approved the Amendment at a meeting held on October 24, 2022. As part
of the review process, the Board reviewed information and had preliminary
discussions with the Advisor regarding the proposed Amendment at meetings held
on April 18, 2022, June 12-13, 2022 and September 18-19, 2022. Following those
preliminary discussions, the Board requested and received information from the
Advisor regarding the proposed Amendment, and that information was considered at
an executive session of the Independent Trustees and their counsel held prior to
the October 24, 2022 meeting, as well as at the October meeting.

In reviewing the Amendment, the Board considered that the purpose of the
Amendment is to modify the unitary fee rate for the Fund under the Agreement by
introducing a breakpoint schedule pursuant to which the unitary fee rate paid by
the Fund to the Advisor will be reduced as assets of the Fund meet certain
thresholds. The Board noted the Advisor's representations that the quality and
quantity of the services provided to the Fund by the Advisor under the Agreement
will not be reduced or modified as a result of the Amendment, and that the
obligations of the Advisor under the Agreement will remain the same in all
respects.

The Board noted that it, including the Independent Trustees, last approved the
continuation of the Agreement for a one-year period ending June 30, 2023 at a
meeting held on June 12-13, 2022. The Board noted that in connection with such
approval it had determined, based upon the information provided, that the terms
of the Agreement were fair and reasonable and that the continuation of the
Agreement was in the best interests of the Fund in light of the nature, extent
and quality of the services provided and such other matters as the Board
considered to be relevant in the exercise of its business judgment.

The Board noted that the Advisor had previously agreed to waive a portion of its
unitary fee for the Fund and that the modified unitary fee rate schedule for the
Fund under the Amendment would not be implemented until the expiration of the
Fund's contractual fee waiver. The Board considered that the effective unitary
fee rate paid by the Fund under the Agreement after taking into account the
contractual fee waiver is less than the effective unitary fee rate that the Fund
would pay pursuant to the modified unitary fee rate schedule under the
Amendment.

Based on all of the information considered, the Board, including the Independent
Trustees, unanimously determined that the terms of the Amendment are fair and
reasonable and that the Amendment is in the best interests of the Fund.

REMUNERATION

First Trust Advisors L.P. ("First Trust") is authorised and regulated by the
U.S. Securities and Exchange Commission and is entitled to market shares of
certain funds it manages, including First Trust Enhanced Short Maturity ETF (the
"Fund"), in certain member states in the European Economic Area in accordance
with the cooperation arrangements in Article 42 of the Alternative Investment
Fund Managers Directive (the "Directive"). First Trust is required under the
Directive to make disclosures in respect of remuneration. The following
disclosures are made in line with First Trust's interpretation of currently
available regulatory guidance on remuneration disclosures.

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
OCTOBER 31, 2022 (UNAUDITED)

During the year ended December 31, 2021, the amount of remuneration paid (or to
be paid) by First Trust in respect of the Fund is $6,575,011. This figure is
comprised of $500,890 paid (or to be paid) in fixed compensation and $6,074,121
paid (or to be paid) in variable compensation. There were a total of 28
beneficiaries of the remuneration described above. Those amounts include
$1,234,773 paid (or to be paid) to senior management of First Trust and
$5,340,238 paid (or to be paid) to other employees whose professional activities
have a material impact on the risk profiles of First Trust or the Fund
(collectively, "Code Staff").

Code Staff included in the aggregated figures disclosed above are rewarded in
line with First Trust's remuneration policy (the "Remuneration Policy") which is
determined and implemented by First Trust's senior management. The Remuneration
Policy reflects First Trust's ethos of good governance and encapsulates the
following principal objectives:

i. to provide a clear link between remuneration and performance of
First Trust and to avoid rewarding for failure;

ii. to promote sound and effective risk management consistent with the
risk profiles of the funds managed by First Trust; and

iii. to remunerate staff in line with the business strategy, objectives,
values and interests of First Trust and the funds managed by First
Trust in a manner that avoids conflicts of interest.

First Trust assesses various risk factors which it is exposed to when
considering and implementing remuneration for Code Staff and considers whether
any potential award to such person(s) would give rise to a conflict of interest.
First Trust does not reward failure, or consider the taking of risk or failure
to take risk in its remuneration of Code Staff.

First Trust assesses performance for the purposes of determining payments in
respect of performance-related remuneration of Code Staff by reference to a
broad range of measures including (i) individual performance (using financial
and non-financial criteria), and (ii) the overall performance of First Trust.
Remuneration is not based upon the performance of the Fund.

The elements of remuneration are balanced between fixed and variable and the
senior management sets fixed salaries at a level sufficient to ensure that
variable remuneration incentivises and rewards strong individual performance but
does not encourage excessive risk taking.

No individual is involved in setting his or her own remuneration.
