SHAREHOLDER LETTER
--------------------------------------------------------------------------------

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 JULY 31, 2020

Dear Shareholders:

First Trust is pleased to provide you with the annual report for the Sector
Funds of the First Exchange-Traded AlphaDEX(R) Fund (the "Funds"), which
contains detailed information about the Funds for the 12-month period ended July
31, 2020.

When I think back to the direction the U.S. economy was headed midway through
2018, the first thought that comes to mind is normalization. At that time, it
was a welcome notion. If you recall, the Trump Administration signed the Tax
Cuts & Jobs Act of 2017 on December 22, 2017. Perhaps the most exciting part of
the new tax law was the slashing of the federal corporate tax rate from 35%,
which was among the highest of any country in the world, to 21%. This was well
received, in our opinion. U.S. economic activity was rising even before the ink
was dry on the tax bill. Real U.S. gross domestic product grew at an annualized
rate of 3.9% in the fourth quarter of 2017, and then rose an annualized 3.8% in
the first quarter of 2018, according to the Bureau of Economic Analysis. The
last time U.S. economic growth had exceeded the 3.0% mark was in the first
quarter of 2015. Over the two terms of the Obama Administration (2009-2016),
U.S. economic growth averaged just 2.0%, which was modest by historical
standards. Brian Wesbury, Chief Economist at First Trust Advisors L.P., referred
to it as the "Plow Horse Economy." The main takeaway here is that the Trump
Administration's tax cuts were helping to drive economic growth to more
normalized levels. The process had begun.

As economic growth was normalizing in 2018, so were interest rates and bond
yields. The Federal Reserve (the "Fed") raised the federal funds target rate
(upper bound) from 1.50% at the start of 2018 to 2.50% at year-end, or an
increase of 100 basis points ("bps"). The yield on the 10-Year Treasury Note
("T-Note"), which the Fed does not control, rose 83 bps from the start of 2018
to its calendar year peak of 3.24% on November 8, 2018. The point here is that
while interest rates and bond yields were well into the process of normalizing,
they were still below their historical norms. For the 30-year period ended
December 31, 2018, the federal funds target rate (upper bound) averaged 3.18%,
while the 10-Year T-Note's average yield was 4.71%, according to Bloomberg. If
you recall, industry pundits had been characterizing the persistent low-rate,
low-growth climate as the "new normal." While the concept of getting back to
normal in the economy and markets looked achievable, in the end, it was not
meant to be. What derailed the momentum? In a word: tariffs. In March 2018, less
than three months after enacting its tax reform legislation, the Trump
Administration initiated a tariff program targeting imported goods and services
from the major trading partners of the U.S. In February 2020, the White House
acknowledged that the Trump Administration's trade policies "depressed economic
growth and business investment," according to Bloomberg. President Trump was
pressuring the Fed to lower interest rates months before the coronavirus
("COVID-19") showed itself. The tariffs are still in play today.

Let us fast forward to today's climate. For all intents and purposes, from a
monetary policy standpoint, we are back to where we were following the 2008-2009
financial crisis. The federal funds target rate (upper bound) stood at 0.25% on
July 31, 2020. That is where it sat from December 2008 to December 2015. That
puts us farther away from normalcy than we were leading up to 2018. While the
COVID-19 pandemic was what drove the U.S. economy into a recession and what
pushed the stock market into bear market territory, at least for a few months,
we know that there are other headwinds to be navigated, such as government trade
policies and elections. There are always going to be headwinds to be navigated.
As of July 31, 2020, the yield on the 10-Year T-Note was 0.53%, which was about
150 bps below where it stood at the close of December 2008. The Fed has stated
that it is in no rush to raise interest rates. Inflation levels are subdued. By
keeping interest rates artificially low, the Fed is incentivizing investors to
assume more risk to potentially earn a higher return on their capital. With the
help of the Fed, the stock and bond markets have proved their resiliency once
again, despite how destructive COVID-19 has been to date. Investors should take
solace in that fact. Maybe the new normal will work as well for investors as
what we deemed normal in the past. Stay the course!

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

Sincerely,

/s/ James A. Bowen

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

ROBERT F. CAREY, CFA
SENIOR VICE PRESIDENT AND CHIEF MARKET STRATEGIST
FIRST TRUST ADVISORS L.P.

Mr. Carey is responsible for the overall management of research and analysis of
the First Trust product line. Mr. Carey has over 27 years of experience as an
Equity and Fixed-Income Analyst and is a recipient of the Chartered Financial
Analyst ("CFA") designation. He is a graduate of the University of Illinois at
Champaign-Urbana with a B.S. in Physics. He is also a member of the Investment
Analysts Society of Chicago and the CFA Institute. Mr. Carey has appeared as a
guest on such programs as Bloomberg TV, CNBC, and WBBM Radio, and has been
quoted by several publications, including The Wall Street Journal, The Wall
Street Reporter, Bloomberg News Service, and Registered Rep.

STATE OF THE U.S. ECONOMY

A year ago, we were laser focused on the Trump Administration's trade war with
China. Little did we know back then that we would be swapping anxiety over
tariffs for a virus pandemic. The coronavirus ("COVID-19") has been front and
center since its onset early in the first quarter of 2020. Its arrival ended the
bull market in stocks and temporarily shuttered a major chunk of not only the
U.S. economy, but economies around the globe. The U.S. economy contracted by an
annualized 5.0% in the first quarter of 2020 and then plunged an annualized
32.9% in the second quarter of 2020, according to the Bureau of Economic
Analysis. The National Bureau of Economic Research, the organization that
determines the beginning and end of business cycles in the U.S., reported on
June 8, 2020, that U.S. economic activity peaked in February of this year. That
marked the end of a 128-month economic expansion, the longest in this nation's
history. We now know that the U.S. economy is in a recession.

While the trillions of dollars of stimulus that has been appropriated by
government leaders and central bankers throughout the globe is helping to prop
up economies decimated (financial cost and human toll) by COVID-19, we believe
that its primary objective is to simply buy time so that health care companies
can develop therapeutics and vaccines to combat the virus. There are indicators
we can cite that show just how rough it is in the business world despite the
stimulus efforts. One of our go to barometers is the default rate on
lower-quality, high yield corporate bonds. As of July 31, 2020, the trailing
12-month global speculative-grade default rate was 6.1%, according to Moody's
Investors Service. It now stands above its historical average of 4.1%. Moody's
estimates that it will climb to 8.8% by the end of 2020. That happens to
coincide with the target date for when some pundits believe we could see the
first FDA-approved vaccines for COVID-19. This is something we plan to monitor
closely.

The International Monetary Fund ("IMF") is forecasting year-over-year global
growth rate estimates of -4.9% for 2020 and 5.4% for 2021, compared to 3.6% in
2018 and 2.9% in 2019. With respect to the U.S., it sees gross domestic product
growth declining by an estimated 8.0% in 2020 and then rebounding 4.5% in 2021.
That is in line with the -8.0% and 4.8% estimates for 2020 and 2021 for all
Advanced Economies. Emerging Market and Developing Economies are expected to
hold up better than their developed nation counterparts. The IMF puts their
growth rate targets at -3.0% for 2020 and 5.9% for 2021.

ETFGI, an independent research and consultancy firm, reported that total assets
invested in exchange-traded funds ("ETFs") and related exchange-traded products
("ETPs") listed globally stood at an all-time high of $6.66 trillion in July
2020, up from $5.74 trillion a year ago, according to its own release. Total
assets of U.S. listed ETFs/ETPs stood at an all-time high of $4.61 trillion, up
from $4.02 trillion a year ago.

SECTOR/EQUITY INVESTING

One barometer for gauging investors' appetites for equities is tracking money
flows in and out of open-end mutual funds and ETFs. The flows are reported over
time on a rolling 12-month basis. For the 12-month period ended July 31, 2020,
U.S. Equity funds/ETFs reported estimated net outflows totaling $177.64 billion,
according to data from Morningstar. As has been the case in recent years,
investors are favoring passive funds over actively managed funds. Passive U.S.
Equity funds/ETFs reported estimated net inflows totaling $62.14 billion,
compared to estimated net outflows totaling $239.78 billion for actively managed
U.S. Equity funds/ETFs.

Investors were net buyers of sector funds and ETFs over the past year. For the
12-month period ended July 31, 2020, Sector Equity funds/ETFs reported estimated
net inflows totaling $5.30 billion. Passive Sector Equity funds/ETFs reported
estimated net inflows totaling $23.44 billion, compared to estimated net
outflows totaling $18.14 billion for actively managed Sector Equity funds/ETFs
for the same period.

For the 12-month period ended July 31, 2020, eight of the 11 major sectors that
comprise the S&P 500(R) Index (the "Index") generated positive total returns,
according to Bloomberg. The Index posted a total return of 11.96% over the
period. Four of the 11 sectors outperformed the broader index. Those four
sectors were as follows: Information Technology (+38.91%); Consumer
Discretionary (+21.57%); Health Care (+18.77%); and Communication Services
(+14.76%), according to Bloomberg. The three sectors that posted negative total
returns for the period were Energy, Financials and Industrials, down 38.26%,
12.81% and 5.70%, respectively.

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

FIRST TRUST CONSUMER DISCRETIONARY ALPHADEX(R) FUND (FXD)

The First Trust Consumer Discretionary AlphaDEX(R) Fund (the "Fund") seeks
investment results that correspond generally to the price and yield (before the
Fund's fees and expenses) of an equity index called the StrataQuant(R) Consumer
Discretionary Index (the "Consumer Discretionary Index"). The Fund will normally
invest at least 90% of its net assets (including investment borrowings) in the
common stocks that comprise the Consumer Discretionary Index. The shares of the
Fund are listed and trade on the NYSE Arca, Inc. (the "NYSE Arca" or the
"Exchange") under the ticker symbol "FXD."

The Consumer Discretionary Index is a modified equal-dollar weighted index
designed by ICE Data Indices, LLC or its affiliates ("IDI") to objectively
identify and select stocks from the Russell 1000(R) Index in the consumer
discretionary sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Consumer
Discretionary Index using the Industry Classification Benchmark ("ICB") sector
scheme to determine a stock's sector membership.

Discretionary Index (the "Benchmark") generated a return of 21.57%. The
Specialty Retail industry was the industry with the greatest allocation in the
Fund during the period. This industry had an average weight of 17.2% in the Fund
but contributed -0.2% to the Fund's performance. The industry with the greatest
contribution to the Fund's return was the Entertainment industry. Investments in
this industry received an allocation of 5.1% and contributed 2.2% to the Fund's
total return. Meanwhile, investments in the Hotels, Restaurants, & Leisure
industry were the most significant drag on the Fund's performance, contributing
-4.1%. On a relative basis, the Fund underperformed the Benchmark. The
underperformance in the Fund during the period came primarily from the Fund's
underweight of Amazon.com, Inc. ("Amazon"). Amazon had a 0.6% allocation in the
Fund and a 33.9% weight in the Benchmark. This security alone accounted for
-15.0% of underperformance for the Fund versus the Benchmark. The Internet &
Direct Marketing Retail industry, overall, caused -13.9% of underperformance for
the Fund. There was some outperformance for the Fund which came from investments
in the Automobiles industry, with 3.2% of outperformance earned for the Fund.

(1) On or about September 18, 2008, Russell Investment Group ("Russell") began
calculating its Russell U.S. Indices using an enhanced Russell sector scheme,
the Russell Global Sectors ("RGS"). The RGS and the former U.S. sector scheme
ran in tandem until June 30, 2009, when Russell officially transitioned to the
RGS and ceased calculating its indices using the U.S. sector scheme. In addition
to the implementation of the RGS, Russell changed the name of the Russell
1000(R) Consumer Discretionary and Services Index to the Russell 1000(R)
Consumer Discretionary Index. Consequently, performance data is not available
for all the periods shown in the table for the Russell 1000(R) Consumer
Discretionary Index because performance data does not exist for each of the
entire periods using solely the U.S. sector scheme, or alternatively, using
solely the RGS.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST CONSUMER STAPLES ALPHADEX(R) FUND (FXG)

The First Trust Consumer Staples AlphaDEX(R) Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the StrataQuant(R) Consumer Staples
Index (the "Consumer Staples Index"). The Fund will normally invest at least 90%
of its net assets (including investment borrowings) in the common stocks that
comprise the Consumer Staples Index. The shares of the Fund are listed and trade
on the NYSE Arca under the ticker symbol "FXG."

The Consumer Staples Index is a modified equal-dollar weighted index designed by
IDI to objectively identify and select stocks from the Russell 1000(R) Index in
the consumer staples sector that may generate positive alpha relative to
traditional passive-style indices through the use of the AlphaDEX(R) selection
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. IDI constructs
the Consumer Staples Index using the ICB sector scheme to determine a stock's
sector membership.

PERFORMANCE REVIEW

The Fund generated a NAV return of 8.46% during the period covered by this
report. During the same period, the S&P 500(R) Consumer Staples Index (the
"Benchmark") generated a return of 8.14%. The Food Products industry received
the greatest allocation in the Fund during the period, with an average weight of
43.9%. However, this industry was a relative non-performer for the Fund and
contributed -0.4% to the Fund's overall return. The industry with the greatest
contribution to the Fund's return was the Personal Products industry. These
investments carried an allocation in the Fund of 4.4% and resulted in a 2.7%
contribution to Fund return. Investments in the Chemicals industry caused the
most drag on Fund performance. Fortunately, these investments received an
allocation of only 0.6%, limiting the drag to the Fund's return to only -0.4%.
On a relative basis, the Fund outperformed the Benchmark during the period. The
greatest source of outperformance for the Fund versus the Benchmark during the
period covered by this report came from investments in the Personal Products
industry. The Fund was overweight in this industry and also benefitted from the
selection effect, which resulted in 2.1% of outperformance for the Fund. The
investments in the Food Products industry, meanwhile, earned significant
underperformance for the Fund versus the Benchmark. The Fund maintained a
significant overweight in this industry compared to the Benchmark and
investments in the Food Products industry led to -3.1% of underperformance for
the Fund.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Consumer Staples Index because
performance data does not exist for each of the entire periods using solely the
U.S. sector scheme, or alternatively, using solely the RGS.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST ENERGY ALPHADEX(R) FUND (FXN)

The First Trust Energy AlphaDEX(R) Fund (the "Fund") seeks investment results
that correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the StrataQuant(R) Energy Index (the "Energy
Index"). The Fund will normally invest at least 90% of its net assets (including
investment borrowings) in the common stocks that comprise the Energy Index. The
shares of the Fund are listed and trade on the NYSE Arca under the ticker symbol
"FXN."

The Energy Index is a modified equal-dollar weighted index designed by IDI to
objectively identify and select stocks from the Russell 1000(R) Index in the
energy sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Energy Index
using the ICB sector scheme to determine a stock's sector membership.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. In addition to the implementation of the RGS, Russell combined the
Russell 1000(R) Integrated Oils Index and the Russell 1000(R) Other Energy Index
into one index, the Russell 1000(R) Energy Index. Consequently, performance data
is not available for all the periods shown in the table for the Russell 1000(R)
Energy Index because this index did not exist until on or about September 18,
2008.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)

FIRST TRUST FINANCIALS ALPHADEX(R) FUND (FXO)

The First Trust Financials AlphaDEX(R) Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the StrataQuant(R) Financials Index (the
"Financials Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in the common stocks and real estate
investment trusts ("REITs") that comprise the Financials Index. The shares of
the Fund are listed and trade on the NYSE Arca under the ticker symbol "FXO."

The Financials Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
financial services sector that may generate positive alpha relative to
traditional passive-style indices through the use of the AlphaDEX(R) selection
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. IDI constructs
the Financials Index using the ICB sector scheme to determine a stock's sector
membership.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST HEALTH CARE ALPHADEX(R) FUND (FXH)

The First Trust Health Care AlphaDEX(R) Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the StrataQuant(R) Health Care Index
(the "Health Care Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in the common stocks that comprise the
Health Care Index. The shares of the Fund are listed and trade on the NYSE Arca
under the ticker symbol "FXH."

The Health Care Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
health care sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Health Care
Index using the ICB sector scheme to determine a stock's sector membership.

Outperformance of 3.8% came from the Health Care Equipment & Supplies industry,
which was the industry with the greatest allocation. Multiple industries caused
minimal underperformance, with the most significant coming from the Health Care
Technology industry, which caused -0.5% of underperformance for the Fund versus
the Benchmark.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Health Care Index because performance
data does not exist for each of the entire periods using solely the U.S. sector
scheme, or alternatively, using solely the RGS.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST INDUSTRIALS/PRODUCER DURABLES ALPHADEX(R) FUND (FXR)

The First Trust Industrials/Producer Durables AlphaDEX(R) Fund (the "Fund")
seeks investment results that correspond generally to the price and yield
(before the Fund's fees and expenses) of an equity index called the
StrataQuant(R) Industrials Index (the "Industrials Index"). The Fund will
normally invest at least 90% of its net assets (including investment borrowings)
in the common stocks that comprise the Industrials Index. The shares of the Fund
are listed and trade on the NYSE Arca under the ticker symbol "FXR."

The Industrials Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
industrials and producer durables sectors that may generate positive alpha
relative to traditional passive-style indices through the use of the AlphaDEX(R)
selection methodology. Alpha is an indication of how much an investment
outperforms or underperforms on a risk-adjusted basis relative to its benchmark.
IDI constructs the Industrials Index using the ICB sector scheme to determine a
stock's sector membership.

PERFORMANCE REVIEW

The Fund generated a NAV return of -6.30% during the period covered by this
report. During the same period, the S&P 500(R) Industrials Index (the
"Benchmark") generated a return of -5.70%. During the period covered by this
report, the Machinery and the Aerospace & Defense industries received the
largest allocations of the Fund's portfolio with weights of 19.1% and 11.0%,
respectively. The Fund's allocation to the IT Services industry generated the
largest contribution to the Fund's return at 5.0%. The allocation to the
Airlines industry generated the largest negative contribution to the Fund's
return at -7.7%. On a relative basis, the Fund underperformed the Benchmark. The
greatest source of the Fund's underperformance came from the Airlines industry
which caused -2.5% of underperformance for the Fund versus the Benchmark. The
Fund's allocation to the IT Services industry partially offset the negative
performance by adding 2.4% of outperformance for the Fund relative to the
Benchmark.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Producer Durables Index because
performance data does not exist for each of the entire periods using solely the
U.S. sector scheme, or alternatively, using solely the RGS.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST MATERIALS ALPHADEX(R) FUND (FXZ)

The First Trust Materials AlphaDEX(R) Fund (the "Fund") seeks investment results
that correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the StrataQuant(R) Materials Index (the
"Materials Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in the common stocks that comprise the
Materials Index. The shares of the Fund are listed and trade on the NYSE Arca
under the ticker symbol "FXZ."

The Materials Index is a modified equal-dollar weighted index designed by IDI to
objectively identify and select stocks from the Russell 1000(R) Index in the
materials and processing sector that may generate positive alpha relative to
traditional passive-style indices through the use of the AlphaDEX(R) selection
methodology. Alpha is an indication of how much an investment outperforms or
underperforms on a risk-adjusted basis relative to its benchmark. IDI constructs
the Materials Index using the ICB sector scheme to determine a stock's sector
membership.

PERFORMANCE REVIEW

The Fund generated a NAV return of -4.78% during the period covered by this
report. During the same period, the S&P 500(R) Materials Index (the "Benchmark")
generated a return of 6.28%. During the period covered by this report, the
Chemicals industry received the largest allocation in the Fund with a weight of
42.6%. The largest contribution to the Fund's return was generated by the 20.4%
allocation to the Metals & Mining industry, which provided a 4.2% contribution
to the Fund's return. The Fund's allocation to the Containers & Packaging
industry provided a -4.5% contribution to the Fund's return, which was the
largest negative contribution to the Fund. On a relative basis, the Fund
underperformed the Benchmark. The largest source of this underperformance was
due to the Fund's allocation to the Metals & Mining industry where the Fund's
3.5% contribution from allocation effect was more than offset by the Fund's
security selection effect within the industry, resulting in -3.4% of
underperformance for the Fund compared to the Benchmark. The Fund's relative
underperformance was partially offset by the allocation to the Containers &
Packaging industry which resulted in 2.0% of relative outperformance.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Materials and Processing Index
because performance data does not exist for each of the entire periods using
solely the U.S. sector scheme, or alternatively, using solely the RGS.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST TECHNOLOGY ALPHADEX(R) FUND (FXL)

The First Trust Technology AlphaDEX(R) Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the StrataQuant(R) Technology Index (the
"Technology Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in the common stocks that comprise the
Technology Index. The shares of the Fund are listed and trade on the NYSE Arca
under the ticker symbol "FXL."

The Technology Index is a modified equal-dollar weighted index designed by IDI
to objectively identify and select stocks from the Russell 1000(R) Index in the
technology sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Technology
Index using the ICB sector scheme to determine a stock's sector membership.

PERFORMANCE REVIEW

The Fund generated a NAV return of 29.33% during the period covered by this
report. During the same period, the S&P 500(R) Information Technology Index (the
"Benchmark") generated a return of 38.91%. During the period covered by this
report, the Software industry received the largest allocation to the Fund's
portfolio with a 36.7% weight. This industry also made the largest contribution
to the Fund's return at 20.9%. The allocation to the Communications Equipment
industry caused a -1.0% contribution to the Fund's return, which was the largest
negative contribution to the Fund during the period. On a relative basis, the
Fund underperformed the Benchmark. The largest source of underperformance came
from the Technology Hardware, Storage & Peripherals industry which generated a
-10.8% drag on performance compared to the Benchmark. This underperformance was
partially offset by the Fund's allocation to the IT Services industry which
generated 4.2% of outperformance relative to the Benchmark.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Technology Index because performance
data does not exist for each of the entire periods using solely the U.S. sector
scheme, or alternatively, using solely the RGS.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

FIRST TRUST UTILITIES ALPHADEX(R) FUND (FXU)

The First Trust Utilities AlphaDEX(R) Fund (the "Fund") seeks investment results
that correspond generally to the price and yield (before the Fund's fees and
expenses) of an equity index called the StrataQuant(R) Utilities Index (the
"Utilities Index"). The Fund will normally invest at least 90% of its net assets
(including investment borrowings) in the common stocks that comprise the
Utilities Index. The shares of the Fund are listed and trade on the NYSE Arca
under the ticker symbol "FXU."

The Utilities Index is a modified equal-dollar weighted index designed by IDI to
objectively identify and select stocks from the Russell 1000(R) Index in the
utilities sector that may generate positive alpha relative to traditional
passive-style indices through the use of the AlphaDEX(R) selection methodology.
Alpha is an indication of how much an investment outperforms or underperforms on
a risk-adjusted basis relative to its benchmark. IDI constructs the Utilities
Index using the ICB sector scheme to determine a stock's sector membership.

(1) On or about September 18, 2008, Russell began calculating its Russell U.S.
Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former
U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially
transitioned to the RGS and ceased calculating its indices using the U.S. sector
scheme. Consequently, performance data is not available for all the periods
shown in the table for the Russell 1000(R) Utilities Index because performance
data does not exist for each of the entire periods using solely the U.S. sector
scheme, or alternatively, using solely the RGS.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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

Each Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is calculated. Since shares of each Fund did not trade in the
secondary market until after the Fund's inception, for the period May 8, 2007
(inception) to May 10, 2007 (the first day of secondary market trading) the NAV
of each Fund is used as a proxy for the secondary market trading price to
calculate market returns. NAV and market returns assume that all distributions
have been reinvested in each Fund at NAV and Market Price, respectively.

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

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND

SECTOR FUNDS
UNDERSTANDING YOUR FUND EXPENSES
JULY 31, 2020 (UNAUDITED)

As a shareholder of First Trust Consumer Discretionary AlphaDEX(R) Fund, First
Trust Consumer Staples AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund,
First Trust Financials AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R)
Fund, First Trust Industrials/Producer Durables AlphaDEX(R) Fund, First Trust
Materials AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund or First
Trust Utilities AlphaDEX(R) Fund (each a "Fund" and collectively, the "Funds"),
you incur two types of costs: (1) transaction costs; and (2) ongoing costs,
including management fees, distribution and/or service (12b-1) fees, if any, and
other Fund expenses. This Example is intended to help you understand your
ongoing costs of investing in the Funds and to compare these costs with the
ongoing costs of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended July 31, 2020.

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

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

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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2020

                                1. ORGANIZATION

First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust") is an open-end
management investment company organized as a Massachusetts business trust on
December 6, 2006, and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twenty-one exchange-traded funds considered
either a Sector Fund or a Style Fund. This report covers the nine Sector Funds
listed below. The shares of each Sector Fund are listed and traded on NYSE Arca,
Inc.

    First Trust Consumer Discretionary AlphaDEX(R) Fund - (ticker "FXD")
    First Trust Consumer Staples AlphaDEX(R) Fund - (ticker "FXG")
    First Trust Energy AlphaDEX(R) Fund - (ticker "FXN")
    First Trust Financials AlphaDEX(R) Fund - (ticker "FXO")
    First Trust Health Care AlphaDEX(R) Fund - (ticker "FXH")
    First Trust Industrials/Producer Durables AlphaDEX(R) Fund - (ticker "FXR")
    First Trust Materials AlphaDEX(R) Fund - (ticker "FXZ")
    First Trust Technology AlphaDEX(R) Fund - (ticker "FXL")
    First Trust Utilities AlphaDEX(R) Fund - (ticker "FXU")

Each fund represents a separate series of shares of beneficial interest in the
Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual
funds, each Fund issues and redeems shares on a continuous basis, at net asset
value ("NAV"), only in large specified blocks consisting of 50,000 shares called
a "Creation Unit." Each Fund's Creation Units are generally issued and redeemed
in-kind for securities in which a Fund invests, and in certain circumstances,
for cash, and only to and from broker-dealers and large institutional investors
that have entered into participation agreements. Except when aggregated in
Creation Units, each Fund's shares are not redeemable securities. The investment
objective of each Fund is to seek investment results that correspond generally
to the price and yield (before the Fund's fees and expenses) of the following
indices:

                       2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

Each Fund's NAV is determined daily as of the close of regular trading on the
New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day
the NYSE is open for trading. If the NYSE closes early on a valuation day, the
NAV is determined as of that time. Each Fund's NAV is calculated by dividing the
value of all assets of each Fund (including accrued interest and dividends),
less all liabilities (including accrued expenses and dividends declared but
unpaid), by the total number of shares outstanding.

Each Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Pricing Committee of the Funds'
investment


                                                                         Page 57

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2020

advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"), in
accordance with valuation procedures adopted by the Trust's Board of Trustees,
and in accordance with provisions of the 1940 Act. Investments valued by the
Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to
the Portfolio of Investments. Each Fund's investments are valued as follows:

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding The Nasdaq Stock Market LLC ("Nasdaq") and the
      London Stock Exchange Alternative Investment Market ("AIM")) are valued at
      the last sale price on the exchange on which they are principally traded
      or, for Nasdaq and AIM securities, the official closing price. Securities
      traded on more than one securities exchange are valued at the last sale
      price or official closing price, as applicable, at the close of the
      securities exchange representing the principal market for such securities.

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

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

      Overnight repurchase agreements are valued at amortized cost when it
      represents the best estimate of fair value.

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

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

      5)    price quotes from dealers and/or third-party pricing services;

      6)    relationships among various securities;

      7)    information obtained by contacting the issuer, analysts, or the
            appropriate stock exchange;

      8)    an analysis of the issuer's financial statements; and

      9)    the existence of merger proposals or tender offers that might affect
            the value of the security.

In addition, differences between the prices used to calculate a Fund's NAV and
the prices used by such Fund's corresponding index could result in a difference
between a Fund's performance and the performance of its underlying index.

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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                                 JULY 31, 2020

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value each Fund's investments as of July 31, 2020, is
included with each Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income, if any, is
recorded on the accrual basis.

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

Distributions received from a Fund's investments in real estate investment
trusts ("REITs") may be comprised of return of capital, capital gains and
income. The actual character of the amounts received during the year is not
known until after the REITs' fiscal year end. A Fund records the character of
distributions received from the REITs during the year based on estimates
available. The characterization of distributions received by a Fund may be
subsequently revised based on information received from the REITs after their
tax reporting periods conclude.

C. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES

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

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

D. SECURITIES LENDING

The Funds may lend securities representing up to 33 1/3% of the value of their
total assets to broker-dealers, banks and other institutions to generate
additional income. When a Fund loans its portfolio securities, it will receive,
at the inception of each loan, collateral equal to at least 102% (for domestic
securities) or 105% (for international securities) of the market value of the
loaned securities. The collateral amount is valued at the beginning of each
business day and is compared to the market value of the loaned securities from
the prior business day to determine if additional collateral is required. If
additional collateral is required, a request is sent to the borrower. Securities
lending involves the risk that the Fund may lose money because the borrower of
the Fund's loaned securities fails to return the securities in a timely manner
or at all. The Fund could also lose money in the event of (i) a decline in the
value of the collateral provided for the loaned securities, (ii) a decline in
the value of any investments made with cash collateral or (iii) an increase in
the value of the loaned securities if the borrower does not increase the
collateral accordingly and the borrower fails to return the securities. These
events could also trigger adverse tax consequences for the Funds.

Under the Funds' Securities Lending Agency Agreement, the securities lending
agent will generally bear the risk that a borrower may default on its obligation
to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the
Funds' securities lending agent and is responsible for executing the lending of
the portfolio securities to creditworthy borrowers. The Funds, however, will be
responsible for the risks associated with the investment of cash collateral. A
Fund may lose money on its investment of cash collateral, which may affect its
ability to repay the collateral to the borrower without the use of other Fund
assets. Each Fund that engages in securities lending receives compensation (net
of any rebate and securities lending agent fees) for lending its securities.
Compensation can be in the form of fees received from the securities lending
agent or dividends or interest earned from the investment of cash collateral.
The fees received from the securities lending agent are accrued daily. The
dividend and interest earned on the securities loaned is accounted for in the
same manner as other dividend and interest income. At July 31, 2020, all the
Funds except FXH and FXU had securities in the securities lending program.
During the fiscal year ended July 31, 2020, all the Funds participated in the
securities lending program.

In the event of a default by a borrower with respect to any loan, BBH will
exercise any and all remedies provided under the applicable borrower agreement
to make the Funds whole. These remedies include purchasing replacement
securities by applying the collateral held from the defaulting broker against
the purchase cost of the replacement securities. If, despite such efforts by BBH
to exercise these remedies, a Fund sustains losses as a result of a borrower's
default, BBH will indemnify the Fund by purchasing replacement securities at its
own expense, or paying the Fund an amount equal to the market value of the
replacement securities, subject to certain limitations which are set forth in
detail in the Securities Lending Agency Agreement between the Trust on behalf of
the Funds and BBH.


                                                                         Page 59

                                 JULY 31, 2020

E. REPURCHASE AGREEMENTS

Repurchase agreements involve the purchase of securities subject to the seller's
agreement to repurchase the securities at a mutually agreed upon date and price,
under the terms of a Master Repurchase Agreement ("MRA"). During the term of a
repurchase agreement, the value of the underlying securities held as collateral
on behalf of a Fund, including accrued interest, is required to exceed the value
of the repurchase agreement, including accrued interest. The underlying
securities for all repurchase agreements are held at the Funds' custodian or
designated sub-custodians under tri-party repurchase agreements.

MRAs govern transactions between a Fund and select counterparties. The MRAs
maintain provisions for, among other things, initiation, income payments, events
of default, and maintenance of collateral for repurchase agreements.

Repurchase agreements received for lending securities are collateralized by U.S.
Treasury securities. The U.S. Treasury securities are held in a joint custody
account at BBH on behalf of the Funds participating in the securities lending
program. In the event the counterparty defaults on the repurchase agreement, the
U.S. Treasury securities can either be maintained as part of a Fund's portfolio
or sold for cash. A Fund could suffer a loss to the extent that the proceeds
from the sale of the underlying collateral held by the Fund are less than the
repurchase price and the Fund's costs associated with the delay and enforcement
of the MRA.

While the Funds may invest in repurchase agreements, any repurchase agreements
held by the Funds during the fiscal year ended July 31, 2020, were received as
collateral for lending securities. There were no repurchase agreements held by
the Funds as of July 31, 2020.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

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

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

G. INCOME TAXES

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

The Funds are subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. Taxable years ending 2017, 2018,
2019, and 2020 remain open to federal and state audit. As of July 31, 2020,
management has evaluated the application of these standards to the Funds, and
has determined that no provision for income tax is required in the Funds'
financial statements for uncertain tax positions.

Each Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
Each Fund is subject to certain limitations under U.S. tax rules on the use of
capital loss carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At July 31, 2020, for
federal income tax purposes, each applicable Fund had a capital loss
carryforward available that is shown in the table below, to the extent provided
by regulations, to offset future capital gains. To the extent that these loss
carryforwards are used to offset future capital gains, it is probable that the
capital gains so offset will not be distributed to each applicable Fund's
shareholders.



                                                                               Non-Expiring

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 Funds and in-kind transactions. The results of
operations and net assets were not affected by these adjustments. For the fiscal
year ended July 31, 2020, the adjustments for each Fund were as follows:

H. EXPENSES

Expenses that are directly related to one of the Funds are charged directly to
the respective Fund. General expenses of the Trust are allocated to all the
Funds based upon the net assets of each Fund.

FTP has entered into licensing agreements with IDI for each of the Funds. The
license agreements allow for the use by FTP of certain trademarks and trade
names of IDI. The Funds and First Trust are sub-licensees to the license
agreement. The Funds are required to pay licensing fees, which are shown on the
Statements of Operations.

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

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

For these services, First Trust is paid an annual management fee of 0.50% of
each Fund's average daily net assets. The Trust and First Trust have entered
into an Expense Reimbursement, Fee Waiver and Recovery Agreement ("Recovery
Agreement") in which First Trust has agreed to waive fees and/or reimburse Fund
expenses to the extent that the operating expenses of each Fund (excluding
interest expense, brokerage commissions and other trading expenses, acquired
fund fees and expenses, taxes and extraordinary expenses) exceed 0.70% of
average daily net assets per year (the "Expense Cap"). The Expense Cap will be
in effect until at least November 30, 2021.

Expenses reimbursed and fees waived by First Trust under the Recovery Agreement
are subject to recovery by First Trust for up to three years from the date the
fee or expense was incurred, but no reimbursement payment will be made by a Fund
if it results in the Fund exceeding (i) the applicable expense limitation in
place for the most recent fiscal year for which such expense limitation was in
place, (ii) the applicable expense limitation in place at the time the fees were
waived, or (iii) the current expense limitation. These amounts would be included
in "Expenses previously waived or reimbursed" on the Statements of Operations.

For the fiscal year ended July 31, 2020, there were no fees waived or expenses
reimbursed by First Trust for the Funds. As of July 31, 2020, none of the Funds
had previously waived fees or expenses reimbursed that are subject to recovery.

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

                  5. CREATION, REDEMPTION AND TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker-dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Such transactions are generally permitted on an
in-kind basis, with a balancing cash component to equate the transaction to the
daily NAV per Share of each Fund on the transaction date times the number of
Shares in a Creation Unit. Authorized Participants purchasing Creation Units
must pay to BNYM, as transfer agent, a standard creation transaction fee (the
"Creation Transaction Fee"), which is based on the number of different
securities in a Creation Unit of each Fund. The Creation Transaction Fee is
applicable to each purchase transaction regardless of the number of Creation
Units purchased in the transaction. An additional variable fee of up to three
times the Creation Transaction Fee may be charged to approximate additional
expenses incurred by a Fund with respect to transactions effected outside of the
clearing process (i.e., through a DTC Participant) or to the extent that cash is
used in lieu of securities to purchase Creation Units. The Creation Transaction
Fee may increase or decrease with changes in each Fund's portfolio. The price
for each Creation Unit will equal the daily NAV per Share of a Fund on the
transaction date times the number of Shares in a Creation Unit plus the fees
described above and, if applicable, any transfer taxes.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
which is based on the number of different securities in a Creation Unit of each
Fund. The Redemption Transaction Fee is applicable to each redemption
transaction regardless of the number of Creation Units redeemed in the
transaction. An additional variable fee of up to three times the Redemption
Transaction Fee may be charged to approximate additional expenses incurred by a
Fund with respect to redemptions effected outside of the clearing process or to
the extent that redemptions are for cash.


                                                                         Page 63

                                 JULY 31, 2020

The Redemption Transaction Fee may increase or decrease with changes in each
Fund's portfolio. Each Fund reserves the right to effect redemptions in cash. A
shareholder may request cash redemption in lieu of securities; however, a Fund
may, in its discretion, reject any such request.

                              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 Funds are
authorized to pay an amount up to 0.25% of their average daily net assets each
year to reimburse FTP, the distributor of the Funds, for amounts expended to
finance activities primarily intended to result in the sale of Creation Units or
the provision of investor services. FTP may also use this amount to compensate
securities dealers or other persons that are Authorized Participants for
providing distribution assistance, including broker-dealer and shareholder
support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before November 30, 2021.

                               7. INDEMNIFICATION

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

                              8. SUBSEQUENT EVENTS

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

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

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
ALPHADEX(R) FUND:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statements of assets and liabilities of First
Trust Consumer Discretionary AlphaDEX(R) Fund, First Trust Consumer Staples
AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund, First Trust Financials
AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R) Fund, First Trust
Industrials/Producer Durables AlphaDEX(R) Fund, First Trust Materials
AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund, and First Trust
Utilities AlphaDEX(R) Fund (the "Funds"), each a series of the First Trust
Exchange-Traded AlphaDEX(R) Fund, including the portfolios of investments, as of
July 31, 2020, the related statements 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, and 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 each of the Funds as of July 31, 2020, and the results of their
operations for the year then ended, the changes in their 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 Funds' management. Our responsibility is to express an opinion on the Funds'
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 Funds 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 Funds are 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 Funds' 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 July 31, 2020, 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.

                                  SECTOR FUNDS
                           JULY 31, 2020 (UNAUDITED)


                              RISK CONSIDERATIONS

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

CONCENTRATION RISK. To the extent that a fund is able to invest a large
percentage of its assets in a single asset class or the securities of issuers
within the same country, state, region, industry or sector, an adverse economic,
business or political development may affect the value of the fund's investments
more than if the fund were more broadly diversified. A fund that tracks an index
will be concentrated to the extent the fund's corresponding index is
concentrated. A concentration makes a fund more susceptible to any single
occurrence and may subject the fund to greater market risk than a fund that is
not concentrated.

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

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

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

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

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

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


                                                                         Page 67

                           JULY 31, 2020 (UNAUDITED)

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

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. The unavailability or replacement of LIBOR may affect the value,
liquidity or return on certain fund investments and may result in costs incurred
in connection with closing out positions and entering into new trades. Any
potential effects of the transition away from LIBOR on the fund or on certain
instruments in which the fund invests can be difficult to ascertain, and they
may vary depending on a variety of factors. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, could result in losses to
the fund.

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

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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

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.

                                  SECTOR FUNDS
                           JULY 31, 2020 (UNAUDITED)


                                  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 the
First Trust Exchange-Traded AlphaDEX(R) Fund funds it manages (the "Funds") 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.

During the year ended December 31, 2019, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $2,786,563.
This figure is comprised of $173,009 paid (or to be paid) in fixed compensation
and $2,613,554 paid (or to be paid) in variable compensation. There were a total
of 15 beneficiaries of the remuneration described above. Those amounts include
$1,627,293 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $1,159,270 paid (or to be paid) to other employees whose professional
activities have a material impact on the risk profiles of First Trust Advisors
L.P. or the Funds (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 Funds.

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.

                               ADVISORY AGREEMENT

 BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT

The Board of Trustees of First Trust Exchange-Traded AlphaDEX(R) Fund (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 following nine series of
the Trust (each a "Fund" and collectively, the "Funds"):

         First Trust Consumer Discretionary AlphaDEX(R) Fund (FXD)
         First Trust Consumer Staples AlphaDEX(R) Fund (FXG)
         First Trust Energy AlphaDEX(R) Fund (FXN)

                                                                         Page 69

                                  SECTOR FUNDS
                           JULY 31, 2020 (UNAUDITED)

The Board approved the continuation of the Agreement for each Fund for a
one-year period ending June 30, 2021 at a meeting held on June 8, 2020. The
Board determined for each Fund 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 reasonable business judgment.

To reach this determination for each Fund, 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 May 11, 2020 and June 8, 2020, 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 each Fund (including
the relevant personnel responsible for these services and their experience); the
advisory fee rate payable by each 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 each Fund as compared to expense ratios of
the funds in the Fund's Expense Group and Expense Universe; performance
information for each Fund, including comparisons of each 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 each Fund and the potential for the Advisor to realize
economies of scale, if any; profitability and other financial data for the
Advisor; any fall-out 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 May
11, 2020, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the May
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 8, 2020 meeting, as well as at the meeting held that day.
The Board considered supplemental information provided by the Advisor on the
operations of the Advisor and the performance of the Funds since the onset of
the COVID-19 pandemic. 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 each 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 a Fund knowing that the Advisor manages the Fund and knowing the
Fund's advisory fee.

In reviewing the Agreement for each Fund, 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 each Fund and reviewed all of the services
provided by the Advisor to the Funds, as well as the background and experience
of the persons responsible for such services. 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 each Fund's compliance with the 1940 Act, as well as each 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 Funds. Finally, as part of the Board's
consideration of the Advisor's services, the Advisor, in its written materials
and at the May 11, 2020 meeting, described to the Board the scope of its ongoing
investment in additional infrastructure and personnel to maintain and improve
the quality of services provided to the Funds 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 each Fund by the Advisor under the Agreement have been
and are expected to remain satisfactory and that the Advisor has managed each
Fund consistent with its investment objective, policies and restrictions.

The Board considered the advisory fee rate payable by each Fund under the
Agreement for the services provided. The Board considered that the Advisor
agreed to extend the current expense cap for each Fund through November 30,
2021. For each Fund, the Board noted that expenses reimbursed and fees waived by
the Advisor are subject to recovery by the Advisor for up to three years from
the date the fee was waived or expense was incurred, but no reimbursement
payment will be made by the Fund if it would result in the Fund exceeding (i)
the applicable expense limitation in place for the most recent fiscal year for
which such expense limitation was in place, (ii) the applicable expense
limitation in place at the time the fees were waived, or (iii) the current
expense limitation. The Board received and reviewed information showing the
advisory or unitary fee rates and expense ratios of the peer funds in the
Expense Groups, as well as advisory and unitary fee rates charged by the Advisor
to other fund (including ETFs) and non-fund clients, as applicable. Because each
Fund's Expense Group included peer funds that pay 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 total (net) expense
ratio of each Fund was above the median total (net) expense ratio of the peer
funds in its respective Expense Group. With respect to the Expense Groups, the

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  SECTOR FUNDS
                           JULY 31, 2020 (UNAUDITED)

Board, at the May 11, 2020 meeting, discussed with Broadridge its methodology
for assembling peer groups and discussed with the Advisor limitations in
creating peer groups for index ETFs, including differences in underlying indexes
and index-tracking methodologies that can result in greater management
complexities across seemingly comparable 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 Funds and other non-ETF clients that limited their
comparability. In considering the advisory fee rates 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 each Fund and the other funds in the First Trust Fund
Complex.

The Board considered performance information for each Fund. The Board noted the
process it has established for monitoring each Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor for the Funds. The Board determined that this process continues to
be effective for reviewing each Fund's performance. The Board received and
reviewed information for periods ended December 31, 2019 regarding the
performance of each Fund's underlying index, the correlation between each Fund's
performance and that of its underlying index, each Fund's tracking difference
and each Fund's excess return as compared to its benchmark index. The Board
considered the Advisor's explanations of how the AlphaDEX(R) stock selection
methodology impacts Fund performance in various market environments, and the
Advisor's statement that AlphaDEX(R) is designed to provide long-term
outperformance. Based on the information provided and its ongoing review of
performance, the Board concluded that each Fund was correlated to its underlying
index and that the tracking difference for each Fund was within a reasonable
range. In addition, the Board reviewed data prepared by Broadridge comparing
each Fund's performance to that of its respective Performance Universe and to
that of a broad-based benchmark index, but given each Fund's objective of
seeking investment results that correspond generally to the performance of its
underlying index, the Board placed more emphasis on its review of correlation
and tracking difference.

On the basis of all the information provided on the fees, expenses and
performance of each Fund and the ongoing oversight by the Board, the Board
concluded that the advisory fee for each Fund continues to be reasonable and
appropriate in light of the nature, extent and quality of the services provided
by the Advisor to each 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 Funds and noted the Advisor's statement that it believes its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Funds. The Board considered the revenues and allocated costs
(including the allocation methodology) of the Advisor in serving as investment
advisor to each Fund for the twelve months ended December 31, 2019 and the
estimated profitability level for each 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 each Fund was not unreasonable. In addition, the Board
considered fall-out benefits described by the Advisor that may be realized from
its relationship with the Funds. The Board considered that the Advisor had
identified as a fall-out benefit to the Advisor and FTP their exposure to
investors and brokers who, absent their exposure to the Funds, may have had no
dealings with the Advisor or FTP, and noted that the Advisor does not utilize
soft dollars in connection with the Funds. The Board concluded that the
character and amount of potential fall-out 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 each Fund. No single factor was
determinative in the Board's analysis.

                       LIQUIDITY RISK MANAGEMENT PROGRAM

In accordance with Rule 22e-4 under the Investment Company Act of 1940, as
amended (the "1940 Act"), the Funds and each other fund in the First Trust Fund
Complex, other than the closed-end funds, have adopted and implemented a
liquidity risk management program (the "Program") reasonably designed to assess
and manage the funds' liquidity risk, i.e., the risk that a fund could not meet
requests to redeem shares issued by the fund without significant dilution of
remaining investors' interests in the fund. The Board of Trustees of the First
Trust Funds has appointed First Trust Advisors, L.P. (the "Advisor") as the
person designated to administer the Program, and in this capacity the Advisor
performs its duties primarily through the activities and efforts of the First
Trust Liquidity Committee.

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,


                                                                         Page 71

                           JULY 31, 2020 (UNAUDITED)

including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind.

At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4
and the Program, the Advisor provided the Board with a written report prepared
by the Advisor that addressed the operation of the Program during the period
from June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund that is required under the Program to have one, and any material
changes to the Program. Note that because the Funds primarily hold assets that
are highly liquid investments, the Funds have not adopted a highly liquid
investment minimum.

As stated in the written report, during the review period, no fund breached the
15% limitation on illiquid investments, no fund with a highly liquid investment
minimum breached that minimum and no fund filed a Form N-LIQUID. The Advisor
concluded that each fund's investment strategy is appropriate for an open-end
fund; that the Program operated effectively in all material respects during the
review period; and that the Program is reasonably designed to assess and manage
the liquidity risk of each fund and to maintain compliance with Rule 22e-4.

                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS

This report contains certain forward-looking statements within the meaning of
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and its representatives, taking into account the
information currently available to them. Forward-looking statements include all
statements that do not relate solely to current or historical fact. For example,
forward-looking statements include the use of words such as "anticipate,"
"estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or
other words that convey uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
any series of First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust")
described in this report (each such series is referred to as a "Fund" and
collectively, as the "Funds") to be materially different from any future
results, performance or achievements expressed or implied by the forward-looking
statements. When evaluating the information included in this report, you are
cautioned not to place undue reliance on these forward-looking statements, which
reflect the judgment of the Advisor and its representatives only as of the date
hereof. We undertake no obligation to publicly revise or update these
forward-looking statements to reflect events and circumstances that arise after
the date hereof.

                        PERFORMANCE AND RISK DISCLOSURE

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

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

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 JULY 31, 2020

Dear Shareholders:

First Trust is pleased to provide you with the annual report for the Style Funds
of the First Exchange-Traded AlphaDEX(R) Fund (the "Funds"), which contains
detailed information about the Funds for the 12-month period ended July 31,
2020.

When I think back to the direction the U.S. economy was headed midway through
2018, the first thought that comes to mind is normalization. At that time, it
was a welcome notion. If you recall, the Trump Administration signed the Tax
Cuts & Jobs Act of 2017 on December 22, 2017. Perhaps the most exciting part of
the new tax law was the slashing of the federal corporate tax rate from 35%,
which was among the highest of any country in the world, to 21%. This was well
received, in our opinion. U.S. economic activity was rising even before the ink
was dry on the tax bill. Real U.S. gross domestic product grew at an annualized
rate of 3.9% in the fourth quarter of 2017, and then rose an annualized 3.8% in
the first quarter of 2018, according to the Bureau of Economic Analysis. The
last time U.S. economic growth had exceeded the 3.0% mark was in the first
quarter of 2015. Over the two terms of the Obama Administration (2009-2016),
U.S. economic growth averaged just 2.0%, which was modest by historical
standards. Brian Wesbury, Chief Economist at First Trust Advisors L.P., referred
to it as the "Plow Horse Economy." The main takeaway here is that the Trump
Administration's tax cuts were helping to drive economic growth to more
normalized levels. The process had begun.

As economic growth was normalizing in 2018, so were interest rates and bond
yields. The Federal Reserve (the "Fed") raised the federal funds target rate
(upper bound) from 1.50% at the start of 2018 to 2.50% at year-end, or an
increase of 100 basis points ("bps"). The yield on the 10-Year Treasury Note
("T-Note"), which the Fed does not control, rose 83 bps from the start of 2018
to its calendar year peak of 3.24% on November 8, 2018. The point here is that
while interest rates and bond yields were well into the process of normalizing,
they were still below their historical norms. For the 30-year period ended
December 31, 2018, the federal funds target rate (upper bound) averaged 3.18%,
while the 10-Year T-Note's average yield was 4.71%, according to Bloomberg. If
you recall, industry pundits had been characterizing the persistent low-rate,
low-growth climate as the "new normal." While the concept of getting back to
normal in the economy and markets looked achievable, in the end, it was not
meant to be. What derailed the momentum? In a word: tariffs. In March 2018, less
than three months after enacting its tax reform legislation, the Trump
Administration initiated a tariff program targeting imported goods and services
from the major trading partners of the U.S. In February 2020, the White House
acknowledged that the Trump Administration's trade policies "depressed economic
growth and business investment," according to Bloomberg. President Trump was
pressuring the Fed to lower interest rates months before the coronavirus
("COVID-19") showed itself. The tariffs are still in play today.

Let us fast forward to today's climate. For all intents and purposes, from a
monetary policy standpoint, we are back to where we were following the 2008-2009
financial crisis. The federal funds target rate (upper bound) stood at 0.25% on
July 31, 2020. That is where it sat from December 2008 to December 2015. That
puts us farther away from normalcy than we were leading up to 2018. While the
COVID-19 pandemic was what drove the U.S. economy into a recession and what
pushed the stock market into bear market territory, at least for a few months,
we know that there are other headwinds to be navigated, such as government trade
policies and elections. There are always going to be headwinds to be navigated.
As of July 31, 2020, the yield on the 10-Year T-Note was 0.53%, which was about
150 bps below where it stood at the close of December 2008. The Fed has stated
that it is in no rush to raise interest rates. Inflation levels are subdued. By
keeping interest rates artificially low, the Fed is incentivizing investors to
assume more risk to potentially earn a higher return on their capital. With the
help of the Fed, the stock and bond markets have proved their resiliency once
again, despite how destructive COVID-19 has been to date. Investors should take
solace in that fact. Maybe the new normal will work as well for investors as
what we deemed normal in the past. Stay the course!

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

Sincerely,

/s/ James A. Bowen

Chairman of the Board of Trustees

SENIOR VICE PRESIDENT AND CHIEF MARKET STRATEGIST
FIRST TRUST ADVISORS L.P.

STATE OF THE U.S./GLOBAL ECONOMY

A year ago, we were laser focused on the Trump Administration's trade war with
China. Little did we know back then that we would be swapping anxiety over
tariffs for a virus pandemic. The coronavirus ("COVID-19") has been front and
center since its onset early in the first quarter of 2020. Its arrival ended the
bull market in stocks and temporarily shuttered a major chunk of not only the
U.S. economy, but economies around the globe. The U.S. economy contracted by an
annualized 5.0% in the first quarter of 2020 and then plunged an annualized
32.9% in the second quarter of 2020, according to the Bureau of Economic
Analysis. The National Bureau of Economic Research, the organization that
determines the beginning and end of business cycles in the U.S., reported on
June 8, 2020, that U.S. economic activity peaked in February of this year. That
marked the end of a 128-month economic expansion, the longest in this nation's
history. We now know that the U.S. economy is in a recession.

While the trillions of dollars of stimulus that has been appropriated by
government leaders and central bankers throughout the globe is helping to prop
up economies decimated (financial cost and human toll) by COVID-19, we believe
that its primary objective is to simply buy time so that health care companies
can develop therapeutics and vaccines to combat the virus. There are indicators
we can cite that show just how rough it is in the business world despite the
stimulus efforts. One of our go to barometers is the default rate on
lower-quality, high yield corporate bonds. As of July 31, 2020, the trailing
12-month global speculative-grade default rate was 6.1%, according to Moody's
Investors Service. It now stands above its historical average of 4.1%. Moody's
estimates that it will climb to 8.8% by the end of 2020. That happens to
coincide with the target date for when some pundits believe we could see the
first FDA-approved vaccines for COVID-19. This is something we plan to monitor
closely.

The International Monetary Fund ("IMF") is forecasting year-over-year global
growth rate estimates of -4.9% for 2020 and 5.4% for 2021, compared to 3.6% in
2018 and 2.9% in 2019. With respect to the U.S., it sees gross domestic product
growth declining by an estimated 8.0% in 2020 and then rebounding 4.5% in 2021.
That is in line with the -8.0% and 4.8% estimates for 2020 and 2021 for all
Advanced Economies. Emerging Market and Developing Economies are expected to
hold up better than their developed nation counterparts. The IMF puts their
growth rate targets at -3.0% for 2020 and 5.9% for 2021.

ETFGI, an independent research and consultancy firm, reported that total assets
invested in exchange-traded funds ("ETFs") and related exchange-traded products
("ETPs") listed globally stood at an all-time high of $6.66 trillion in July
2020, up from $5.74 trillion a year ago, according to its own release. Total
assets of U.S. listed ETFs/ETPs stood at an all-time high of $4.61 trillion, up
from $4.02 trillion a year ago.

STYLE/EQUITY INVESTING

One barometer for gauging investors' appetites for equities is tracking money
flows in and out of open-end mutual funds and ETFs. The flows are reported over
time on a rolling 12-month basis. For the 12-month period ended July 31, 2020,
U.S. Equity funds/ETFs reported estimated net outflows totaling $177.64 billion,
according to data from Morningstar. As has been the case in recent years,
investors are favoring passive funds over actively managed funds. Passive U.S.
Equity funds/ETFs reported estimated net inflows totaling $62.14 billion,
compared to estimated net outflows totaling $239.78 billion for actively managed
U.S. Equity funds/ETFs.

For the 12-month period ended July 31, 2020, U.S. Large Blend, U.S. Large Growth
and U.S. Large Value equity funds/ETFs reported estimated net flows totaling
-$4.81 billion, -$59.38 billion and -$29.68 billion, respectively, according to
Morningstar. U.S. Mid-Cap Blend, U.S. Mid-Cap Growth and U.S. Mid-Cap Value
equity funds/ETFs reported estimated net flows totaling -$12.34 billion, -$14.30
billion and -$21.91 billion, respectively. U.S. Small Blend, U.S. Small Growth
and U.S. Small Value equity funds/ETFs reported estimated net flows totaling
-$10.30 billion, -$12.44 billion and -$2.99 billion, respectively. Overall,
investors were not particularly interested in style-driven portfolios over the
past year.

For the 12-month period ended July 31, 2020, the S&P 500(R) Index posted a total
return of 11.96%, according to Bloomberg. Growth stocks outperformed value
stocks by a huge margin for the same period. The S&P 500(R) Growth Index posted
a total return of 24.55%, compared to -2.72% for the S&P 500(R) Value Index in
the period. The S&P MidCap 400(R) Index posted a total return of -3.54% for the
same period. Growth stocks significantly outperformed value stocks in the
period. The S&P MidCap 400(R) Growth Index posted a total return of 5.38%,
compared to -13.39% for the S&P MidCap 400(R) Value Index. The S&P SmallCap
600(R) Index posted a total return of -8.68% in the period. Despite posting a
negative return, growth stocks outperformed value stocks in the period. The S&P
SmallCap 600(R) Growth Index posted a total return of -1.58%, compared to
-16.31% for the S&P SmallCap 600(R) Value Index for the same period.

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

FIRST TRUST LARGE CAP CORE ALPHADEX(R) FUND (FEX)

The First Trust Large Cap Core AlphaDEX(R) Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the Nasdaq AlphaDEX(R) Large Cap Core
Index (the "Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in the common stocks that comprise the
Index. The shares of the Fund are listed and trade on The Nasdaq Stock Market
LLC under the ticker symbol "FEX."

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select stocks from the
Nasdaq US 500 Large Cap Index that may generate positive alpha relative to
traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

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

of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

PERFORMANCE REVIEW

The Fund generated a NAV return of -5.86% during the period covered by this
report. During the same period, the S&P MidCap 400(R) Index (the "Benchmark")
generated a return of -3.54%. During the period covered by this report, the
Financials sector received the largest allocation within the Fund at a 19.3%
weight. This sector also generated the largest negative contribution to the
Fund's return during the period at -8.2%. The Fund's allocation to the Health
Care sector generated a 5.2% contribution to the Fund's return during the
period, which was the largest return contribution by sector. On a relative
basis, the Fund underperformed the Benchmark. The bulk of this underperformance
came from the Financials sector, where the Fund's holdings within this sector
underperformed the Benchmark's sector holdings by -2.4%. The Fund's holdings
within the Health Care sector minimized a portion of the Fund's relative
underperformance by earning 2.1% of outperformance for the Fund compared to the

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the index does
not actually hold a portfolio of securities and therefore does not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

FIRST TRUST LARGE CAP VALUE ALPHADEX(R) FUND (FTA)

The First Trust Large Cap Value AlphaDEX(R) Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the Nasdaq AlphaDEX(R) Large Cap Value
Index (the "Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in the common stocks that comprise the
Index. The shares of the Fund are listed and trade on The Nasdaq Stock Market
LLC under the ticker symbol "FTA."

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select stocks from the
Nasdaq US 500 Large Cap Value Index that may generate positive alpha relative to
traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FIRST TRUST MULTI CAP VALUE ALPHADEX(R) FUND (FAB)

The First Trust Multi Cap Value AlphaDEX(R) Fund (the "Fund") seeks investment
results that correspond generally to the price and yield (before the Fund's fees
and expenses) of an equity index called the Nasdaq AlphaDEX(R) Multi Cap Value
Index (the "Index"). The Fund will normally invest at least 90% of its net
assets (including investment borrowings) in the common stocks that comprise the
Index. The shares of the Fund are listed and trade on The Nasdaq Stock Market
LLC under the ticker symbol "FAB."

The Index employs the AlphaDEX(R) stock selection methodology which uses
fundamental growth and value factors to objectively select value stocks from the
Nasdaq US 500 Large Cap Value Index, Nasdaq US 600 Mid Cap Value Index, and
Nasdaq US 700 Small Cap Value Index (together, the "Nasdaq US Multi Cap Value
Index") that may generate positive alpha relative to traditional passive
indices. The Index is a modified equal-dollar weighted index where higher ranked
stocks receive a higher weight within the Index.

PERFORMANCE REVIEW

The Fund generated a NAV return of -12.24% during the period covered by this
report. During the same period, the S&P Composite 1500(R) Value Index (the
"Benchmark") generated a return of -3.81%. During the period covered by this
report, the Fund's performance suffered from its allocation to the Financials
sector. The Financials sector received an allocation of 24.2%, which was a
greater weight than any other sector. The investments in the Financials sector
contributed -7.8% to the Fund's return, which was more negative than any other
sector. Meanwhile, the most positively contributing sector was the Health Care
sector. This sector received an allocation of 4.9% and contributed 0.9% to the
Fund's return. On a relative basis, the Fund underperformed the Benchmark. Much
of this underperformance came from the heavily weighted Financials sector, which
contributed -2.5% to the Fund's underperformance versus the Benchmark. However,
investments in the Energy sector were a bright spot for the Fund, at least in
relation to the Benchmark. Investments in this sector contributed -0.4% to the
Fund's return, but 3.1% to the Fund's outperformance versus the Benchmark.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the index does
not actually hold a portfolio of securities and therefore does not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

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.

comparative purposes only and represent the period August 1, 2015 through July

receive less than NAV when they sell those shares because shares are bought and

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the index does
not actually hold a portfolio of securities and therefore does not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

traditional passive indices. The Index is a modified equal-dollar weighted index
where higher ranked stocks receive a higher weight within the Index.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the index does
not actually hold a portfolio of securities and therefore does not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2020

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 1, 2015 through July
31, 2020. Shareholders may pay more than NAV when they buy Fund shares and
receive less than NAV when they sell those shares because shares are bought and
sold at current market price. Data presented represents past performance and
cannot be used to predict future results.

NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

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

Each Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is calculated. Since shares of each Fund did not trade in the
secondary market until after the Fund's inception, for the period from inception
to the first day of secondary market trading in shares of the Fund, the NAV of
each Fund is used as a proxy for the secondary market trading price to calculate
market returns. NAV and market returns assume that all distributions have been
reinvested in each Fund at NAV and Market Price, respectively.

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

UNDERSTANDING YOUR FUND EXPENSES
JULY 31, 2020 (UNAUDITED)

As a shareholder of First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid
Cap Core AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First
Trust Large Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R)
Fund, First Trust Multi Cap Value AlphaDEX(R) Fund, First Trust Multi Cap Growth
AlphaDEX(R) Fund, First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid
Cap Growth AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First
Trust Small Cap Growth AlphaDEX(R) Fund or First Trust Mega Cap AlphaDEX(R) Fund
(each a "Fund" and collectively, the "Funds"), you incur two types of costs: (1)
transaction costs; and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, if any, and other Fund expenses. This
Example is intended to help you understand your ongoing costs of investing in
the Funds and to compare these costs with the ongoing costs of investing in
other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended July 31, 2020.

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

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

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

Offsetting assets and liabilities requires entities to disclose both gross and
net information about instruments and transactions eligible for offset, and to
disclose instruments and transactions subject to master netting or similar
agreements (see Note 2C - Offsetting on the Statements of Assets and Liabilities
in the Notes to Financial Statements).

The Fund's loaned securities were all subject to an enforceable Securities

                                1. ORGANIZATION

First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust") is an open-end
management investment company organized as a Massachusetts business trust on
December 6, 2006, and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twenty-one exchange-traded funds considered
either a Sector Fund or Style Fund. This report covers the twelve Style Funds
listed below. The shares of each Style Fund are listed and traded on The Nasdaq
Stock Market LLC ("Nasdaq").

        First Trust Large Cap Core AlphaDEX(R) Fund - (ticker "FEX")
        First Trust Mid Cap Core AlphaDEX(R) Fund - (ticker "FNX")
        First Trust Small Cap Core AlphaDEX(R) Fund - (ticker "FYX")
        First Trust Large Cap Value AlphaDEX(R) Fund - (ticker "FTA")
        First Trust Large Cap Growth AlphaDEX(R) Fund - (ticker "FTC")
        First Trust Multi Cap Value AlphaDEX(R) Fund - (ticker "FAB")
        First Trust Multi Cap Growth AlphaDEX(R) Fund - (ticker "FAD")
        First Trust Mid Cap Value AlphaDEX(R) Fund - (ticker "FNK")

        First Trust Small Cap Growth AlphaDEX(R) Fund - (ticker "FYC")
        First Trust Mega Cap AlphaDEX(R) Fund - (ticker "FMK")

Each fund represents a separate series of shares of beneficial interest in the
Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual
funds, each Fund issues and redeems shares on a continuous basis, at net asset
value ("NAV"), only in large specified blocks consisting of 50,000 shares called
a "Creation Unit." Each Fund's Creation Units are generally issued and redeemed
in-kind for securities in which a Fund invests and, in certain circumstances,
for cash, and only to and from broker-dealer and large institutional investors
that have entered into participation agreements. Except when aggregated in
Creation Units, each Fund's shares are not redeemable securities. The investment
objective of each Fund is to seek investment results that correspond generally
to the price and yield (before the Fund's fees and expenses) of the following
indices:

                       2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

Each Fund's NAV is determined daily as of the close of regular trading on the
New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day
the NYSE is open for trading. If the NYSE closes early on a valuation day, the
NAV is determined as of that time. Each Fund's NAV is calculated by dividing the
value of all assets of each Fund (including accrued interest and dividends),
less all liabilities (including accrued expenses and dividends declared but
unpaid), by the total number of shares outstanding.


                                                                        Page 119

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                                 JULY 31, 2020

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

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding Nasdaq and the London Stock Exchange
      Alternative Investment Market ("AIM")) are valued at the last sale price
      on the exchange on which they are principally traded or, for Nasdaq and
      AIM securities, the official closing price. Securities traded on more than
      one securities exchange are valued at the last sale price or official
      closing price, as applicable, at the close of the securities exchange
      representing the principal market for such securities.

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

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

      Overnight repurchase agreements are valued at amortized cost when it
      represents the best estimate of fair value.

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

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

      5)    price quotes from dealers and/or third-party pricing services;

      6)    relationships among various securities;

      7)    information obtained by contacting the issuer, analysts, or the
            appropriate stock exchange;

      8)    an analysis of the issuer's financial statements; and

      9)    the existence of merger proposals or tender offers that might affect
            the value of the security.

In addition, differences between the prices used to calculate a Fund's NAV and
the prices used by such Fund's corresponding index could result in a difference
between a Fund's performance and the performance of its underlying index.

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

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

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value each Fund's investments as of July 31, 2020, is
included with each Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income, if any, is
recorded on the accrual basis.

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

Distributions received from a Fund's investments in real estate investment
trusts ("REITs") may be comprised of return of capital, capital gains and
income. The actual character of the amounts received during the year is not
known until after the REITs' fiscal year end. A Fund records the character of
distributions received from the REITs during the year based on estimates
available. The characterization of distributions received by a Fund may be
subsequently revised based on information received from the REITs after their
tax reporting periods conclude.

C. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES

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

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

D. SECURITIES LENDING

The Funds may lend securities representing up to 33 1/3% of the value of their
total assets to broker-dealers, banks and other institutions to generate
additional income. When a Fund loans its portfolio securities, it will receive,
at the inception of each loan, collateral equal to at least 102% (for domestic
securities) or 105% (for international securities) of the market value of the
loaned securities. The collateral amount is valued at the beginning of each
business day and is compared to the market value of the loaned securities from
the prior business day to determine if additional collateral is required. If
additional collateral is required, a request is sent to the borrower. Securities
lending involves the risk that the Fund may lose money because the borrower of
the Fund's loaned securities fails to return the securities in a timely manner
or at all. The Fund could also lose money in the event of (i) a decline in the
value of the collateral provided for the loaned securities, (ii) a decline in
the value of any investments made with cash collateral or (iii) an increase in
the value of the loaned securities if the borrower does not increase the
collateral accordingly and the borrower fails to return the securities. These
events could also trigger adverse tax consequences for the Funds.

Under the Funds' Securities Lending Agency Agreement, the securities lending
agent will generally bear the risk that a borrower may default on its obligation
to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the
Funds' securities lending agent and is responsible for executing the lending of
the portfolio securities to creditworthy borrowers. The Funds, however, will be
responsible for the risks associated with the investment of cash collateral. A
Fund may lose money on its investment of cash collateral, which may affect its
ability to repay the collateral to the borrower without the use of other Fund
assets. Each Fund that engages in securities lending receives compensation (net
of any rebate and securities lending agent fees) for lending its securities.
Compensation can be in the form of fees received from the securities lending
agent or dividends or interest earned from the investment of cash collateral.
The fees received from the securities lending agent are accrued daily. The


                                                                        Page 121

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS

dividend and interest earned on the securities loaned is accounted for in the
same manner as other dividend and interest income. At July 31, 2020, all the
Funds except FMK had securities in the securities lending program. During the
fiscal year ended July 31, 2020, all the Funds except FMK participated in the
securities lending program.

In the event of a default by a borrower with respect to any loan, BBH will
exercise any and all remedies provided under the applicable borrower agreement
to make the Funds whole. These remedies include purchasing replacement
securities by applying the collateral held from the defaulting broker against
the purchase cost of the replacement securities. If, despite such efforts by BBH
to exercise these remedies, a Fund sustains losses as a result of a borrower's
default, BBH will indemnify the Fund by purchasing replacement securities at its
own expense, or paying the Fund an amount equal to the market value of the
replacement securities, subject to certain limitations which are set forth in
detail in the Securities Lending Agency Agreement between the Trust on behalf of
the Funds and BBH.

E. REPURCHASE AGREEMENTS

Repurchase agreements involve the purchase of securities subject to the seller's
agreement to repurchase the securities at a mutually agreed upon date and price,
under the terms of a Master Repurchase Agreement ("MRA"). During the term of a
repurchase agreement, the value of the underlying securities held as collateral
on behalf of a Fund, including accrued interest, is required to exceed the value
of the repurchase agreement, including accrued interest. The underlying
securities for all repurchase agreements are held at the Funds' custodian or
designated sub-custodians under tri-party repurchase agreements.

MRAs govern transactions between a Fund and select counterparties. The MRAs
contain provisions for, among other things, initiation, income payments, events
of default, and maintenance of collateral for repurchase agreements.

Repurchase agreements received for lending securities are collateralized by U.S.
Treasury securities. The U.S. Treasury securities are held in a joint custody
account at BBH on behalf of the Funds participating in the securities lending
program. In the event the counterparty defaults on the repurchase agreement, the
U.S. Treasury securities can either be maintained as part of a Fund's portfolio
or sold for cash. A Fund could suffer a loss to the extent that the proceeds
from the sale of the underlying collateral held by the Fund are less than the
repurchase price and the Fund's costs associated with the delay and enforcement
of the MRA.

While the Funds may invest in repurchase agreements, any repurchase agreements
held by the Funds during the fiscal year ended July 31, 2020, were received as
collateral for lending securities. There were no repurchase agreements held by
the Funds as of July 31, 2020.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

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

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

G. INCOME TAXES

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

The Funds are subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. Taxable years ending 2017, 2018,
2019, and 2020 remain open to federal and state audit. As of July 31, 2020,
management has evaluated the application of these standards to the Funds, and
has determined that no provision for income tax is required in the Funds'
financial statements for uncertain tax positions.

Each Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
Each Fund is subject to certain limitations under U.S. tax rules on the use of
capital loss carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At July 31, 2020, for
federal income tax purposes, each applicable Fund had a capital loss
carryforward available that is shown in the table below, to the extent provided
by regulations, to offset future capital gains. To the extent that these loss
carryforwards are used to offset future capital gains, it is probable that the
capital gains so offset will not be distributed to each applicable Fund's

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 July 31, 2020, the Funds 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 Statements 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 Funds and in-kind transactions. The results of
operations and net assets were not affected by these adjustments. For the fiscal
year ended July 31, 2020, the adjustments for each Fund were as follows:



                                                                             Accumulated

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

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

For the Unitary Fee Funds, First Trust is paid an annual unitary management fee
of 0.70% of such Fund's average daily net assets and is responsible for the
expenses of such Fund including the cost of transfer agency, custody, fund
administration, legal, audit, license and other services, and excluding fee
payments under the Investment Management Agreement, distribution and service
fees pursuant to a Rule 12b-1 plan, if any, brokerage expenses, acquired fund
fees and expenses, taxes, interest, and extraordinary expenses.

For the First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core
AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large
Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First
Trust Multi Cap Value AlphaDEX(R) Fund and First Trust Multi Cap Growth
AlphaDEX(R) Fund, First Trust is paid an annual management fee of 0.50% of each
Fund's average daily net assets. For such Funds, the Trust and First Trust have
entered into an Expense Reimbursement, Fee Waiver and Recovery Agreement
("Recovery Agreement") in which First Trust has agreed to waive fees and/or
reimburse Fund expenses to the extent that the operating expenses of each such
Fund (excluding interest expense, brokerage commissions and other trading
expenses, acquired fund fees and expenses, taxes and extraordinary expenses)
exceed 0.70% of average daily net assets per year (the "Expense Cap"). These
Funds will have the Expense Cap in effect until at least November 30, 2021.

Expenses reimbursed and fees waived by First Trust under the Recovery Agreement
are subject to recovery by First Trust for up to three years from the date the
fee was waived or expense was incurred, but no reimbursement payment will be
made by a Fund if it results in the Fund exceeding (i) the applicable expense
limitation in place for the most recent fiscal year for which such expense
limitation was in place (ii) the applicable expense limitation in place at the
time the fees were waived, or (iii) the current expense limitation. These
amounts would be included in "Expenses previously waived or reimbursed" on the
Statements of Operations.

The advisory fee waivers and expense reimbursements for the fiscal year ended
July 31, 2020 and fees waived or expenses borne by First Trust subject to
recovery from the applicable Fund for the periods indicated were as follows:



                                                                  Fees Waived or Expenses Borne by First Trust

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

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

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

                  5. CREATION, REDEMPTION AND TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker-dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Such transactions are generally permitted on an
in-kind basis, with a balancing cash component to equate the transaction to the
daily NAV per Share of each Fund on the transaction date times the number of
Shares in a Creation Unit. Authorized Participants purchasing Creation Units
must pay to BNYM, as transfer agent, a standard creation transaction fee (the
"Creation Transaction Fee"), which is based on the number of different
securities in a Creation Unit of each Fund. The Creation Transaction Fee is
applicable to each purchase transaction regardless of the number of Creation
Units purchased in the transaction. An additional variable fee of up to three
times the Creation Transaction Fee may be charged to approximate additional
expenses incurred by a Fund with respect to transactions effected outside of the
clearing process (i.e., through a DTC Participant) or to the extent that cash is
used in lieu of securities to purchase Creation Units. The Creation Transaction
Fee may increase or decrease with changes in each Fund's portfolio. The price
for each Creation Unit will equal the daily NAV per Share of a Fund on the
transaction date times the number of Shares in a Creation Unit plus the fees
described above and, if applicable, any transfer taxes.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
which is based on the number of different securities in a Creation Unit of each
Fund. The Redemption Transaction Fee is applicable to each redemption
transaction regardless of the number of Creation Units redeemed in the
transaction. An additional variable fee of up to three times the Redemption
Transaction Fee may be charged to approximate additional expenses incurred by a
Fund with respect to redemptions effected outside of the clearing process or to
the extent that redemptions are for cash. The Redemption Transaction Fee may
increase or decrease with changes in each Fund's portfolio. Each Fund reserves
the right to effect redemptions in cash. A shareholder may request cash
redemption in lieu of securities; however, a Fund may, in its discretion, reject
any such request.

                              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 Funds are
authorized to pay an amount up to 0.25% of their average daily net assets each
year to reimburse FTP, the distributor of the Funds, for amounts expended to
finance activities primarily intended to result in the sale of Creation Units or
the provision of investor services. FTP may also use this amount to compensate
securities dealers or other persons that are Authorized Participants for
providing distribution assistance, including broker-dealer and shareholder
support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before November 30, 2021.

                               7. INDEMNIFICATION

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

                              8. SUBSEQUENT EVENTS

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

The Board of Trustees of the Trust has approved a transaction to combine FMK
with First Trust Dow 30 Equal Weight ETF ("EDOW"), an exchange-traded index fund
that seeks investment results that correspond generally to the price and yield
(before fees and expenses) of an equity index called the Dow Jones Industrial
Average Equal Weight Index. Pursuant to this transaction, FMK shareholders will
become shareholders of EDOW.

In order for the transaction to occur, the shareholders of FMK and shareholders
of EDOW must approve the transaction. If approved, shares of FMK would be
exchanged, on a tax-free basis for federal income tax purposes, for shares of
EDOW with an equal aggregate net asset value, and FMK shareholders will become
shareholders of EDOW.

A special meeting of shareholders of FMK for the purpose of voting on the
transaction was held on September 14, 2020 and will reconvene on Monday,
September 28, 2020 at 12:15 p.m. Central time at the offices of FTA at 120 East
Liberty Drive, Suite 400, in Wheaton, Illinois in order to allow shareholders
additional time to vote. If the required approval is obtained, it is anticipated
that the transaction will be consummated shortly after the special shareholder
meeting.

FMK will continue sales and redemptions of shares as described in FMK's
prospectus.


                                                                        Page 127

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

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
ALPHADEX(R) FUND:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statements of assets and liabilities of First
Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core AlphaDEX(R)
Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large Cap Value
AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First Trust
Multi Cap Value AlphaDEX(R) Fund, First Trust Multi Cap Growth AlphaDEX(R) Fund,
First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid Cap Growth
AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First Trust
Small Cap Growth AlphaDEX(R) Fund, and First Trust Mega Cap AlphaDEX(R) Fund
(the "Funds"), each a series of the First Trust Exchange-Traded AlphaDEX(R)
Fund, including the portfolios of investments, as of July 31, 2020, the related
statements 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, and 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 Funds as of July
31, 2020, and the results of their operations for the year then ended, the
changes in their 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 Funds' management. Our responsibility is to express an opinion on the Funds'
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 Funds 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 Funds are 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 Funds' 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 July 31, 2020, by correspondence with the
custodian and brokers. We believe that our audits provide a reasonable basis for
our opinion.

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                           JULY 31, 2020 (UNAUDITED)

                              RISK CONSIDERATIONS

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

CONCENTRATION RISK. To the extent that a fund is able to invest a large
percentage of its assets in a single asset class or the securities of issuers
within the same country, state, region, industry or sector, an adverse economic,
business or political development may affect the value of the fund's investments
more than if the fund were more broadly diversified. A fund that tracks an index
will be concentrated to the extent the fund's corresponding index is
concentrated. A concentration makes a fund more susceptible to any single
occurrence and may subject the fund to greater market risk than a fund that is
not concentrated.

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

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

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

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

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

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

                           JULY 31, 2020 (UNAUDITED)

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

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. The unavailability or replacement of LIBOR may affect the value,
liquidity or return on certain fund investments and may result in costs incurred
in connection with closing out positions and entering into new trades. Any
potential effects of the transition away from LIBOR on the fund or on certain
instruments in which the fund invests can be difficult to ascertain, and they
may vary depending on a variety of factors. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, could result in losses to
the fund.

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

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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

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.

          NOT FDIC INSURED     NOT BANK GUARANTEED     MAY LOSE VALUE

                           JULY 31, 2020 (UNAUDITED)

                                  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 the
First Trust Exchange-Traded AlphaDEX(R) Fund funds it manages (the "Funds") 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.

During the year ended December 31, 2019, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $2,280,220.
This figure is comprised of $141,572 paid (or to be paid) in fixed compensation
and $2,138,648 paid (or to be paid) in variable compensation. There were a total
of 15 beneficiaries of the remuneration described above. Those amounts include
$1,331,600 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $948,620 paid (or to be paid) to other employees whose professional
activities have a material impact on the risk profiles of First Trust Advisors
L.P. or the Funds (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 Funds.

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.

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                           JULY 31, 2020 (UNAUDITED)

        First Trust Small Cap Growth AlphaDEX(R) Fund (FYC)
        First Trust Small Cap Value AlphaDEX(R) Fund (FYT)
        First Trust Mega Cap AlphaDEX(R) Fund (FMK)

The Board approved the continuation of the Agreement for each Fund for a
one-year period ending June 30, 2021 at a meeting held on June 8, 2020. The
Board determined for each Fund 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 reasonable business judgment.

To reach this determination for each Fund, 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 May 11, 2020 and June 8, 2020, 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 each Fund (including
the relevant personnel responsible for these services and their experience); the
advisory or unitary fee rate payable by each 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 each Fund as compared to expense ratios of
the funds in the Fund's Expense Group and Expense Universe; performance
information for each Fund, including comparisons of each 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 each Fund and the potential for the Advisor to realize
economies of scale, if any; profitability and other financial data for the
Advisor; any fall-out 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 May
11, 2020, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the May
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 8, 2020 meeting, as well as at the meeting held that day.
The Board considered supplemental information provided by the Advisor on the
operations of the Advisor and the performance of the Funds since the onset of
the COVID-19 pandemic. 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 each Fund's perspective. The Board
determined that, given the totality of the information provided with respect to
the Agreements, the Board had received sufficient information to renew the
Agreements. The Board considered that shareholders chose to invest or remain
invested in a Fund knowing that the Advisor manages the Fund and knowing the
Fund's advisory or unitary fee.

In reviewing the Agreement for each Fund, 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 each Fund and reviewed all of the services
provided by the Advisor to the Funds, as well as the background and experience
of the persons responsible for such services. 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 each Fund's compliance with the 1940 Act, as well as each 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 Funds. Finally, as part of the Board's
consideration of the Advisor's services, the Advisor, in its written materials
and at the May 11, 2020 meeting, described to the Board the scope of its ongoing
investment in additional infrastructure and personnel to maintain and improve
the quality of services provided to the Funds 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 each Fund by the Advisor under the Agreements have
been and are expected to remain satisfactory and that the Advisor has managed
each Fund consistent with its investment objective, policies and restrictions.

For FEX, FNX, FYX, FAD, FAB, FTC and FTA (the "Non-Unitary Fee Funds"), the
Board considered the advisory fee rate payable by each Non-Unitary Fee Fund
under the applicable Agreement for the services provided. The Board considered
that the Advisor agreed to extend the current expense cap for each Non-Unitary
Fee Fund through November 30, 2021. For each Non-Unitary Fee Fund, the Board
noted that expenses reimbursed and fees waived by the Advisor are subject to
recovery by the Advisor for up to three years from the date the fee was waived
or expense was incurred, but no reimbursement payment will be made by the


                                                                        Page 133

ADDITIONAL INFORMATION (CONTINUED)

                  FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
                                  STYLE FUNDS
                           JULY 31, 2020 (UNAUDITED)

Non-Unitary Fee Fund if it would result in the Non-Unitary Fee Fund exceeding
(i) the applicable expense limitation in place for the most recent fiscal year
for which such expense limitation was in place, (ii) the applicable expense
limitation in place at the time the fees were waived, or (iii) the current
expense limitation.

For FNY, FNK, FYC, FYT and FMK (the "Unitary Fee Funds"), the Board considered
the unitary fee rate payable by each Unitary Fee Fund under the applicable
Agreement for the services provided. The Board considered that as part of the
unitary fee the Advisor is responsible for each Unitary Fee 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 applicable Agreement and interest, taxes, brokerage commissions and
other expenses connected with the execution of portfolio transactions,
distribution and service fees pursuant to a Rule 12b-1 plan, if any, and
extraordinary expenses, if any.

The Board received and reviewed information showing the advisory or unitary fee
rates and expense ratios of the peer funds in the Expense Groups, as well as
advisory and unitary fee rates charged by the Advisor to other fund (including
ETFs) and non-fund clients, as applicable. Because each Fund's Expense Group
included peer funds that pay a unitary fee and because each Unitary Fee 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 total (net) expense ratio of each Non-Unitary Fee Fund and the
unitary fee rate for each Unitary Fee Fund were above the median total (net)
expense ratio of the peer funds in each Fund's respective Expense Group. With
respect to the Expense Groups, the Board, at the May 11, 2020 meeting, discussed
with Broadridge its methodology for assembling peer groups and discussed with
the Advisor limitations in creating peer groups for index ETFs, including
differences in underlying indexes and index-tracking methodologies that can
result in greater management complexities across seemingly comparable 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 Funds and other non-ETF
clients that limited their comparability. In considering the advisory and
unitary fee rates 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 each
Fund and the other funds in the First Trust Fund Complex.

The Board considered performance information for each Fund. The Board noted the
process it has established for monitoring each Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor for the Funds. The Board determined that this process continues to
be effective for reviewing each Fund's performance. The Board received and
reviewed information for periods ended December 31, 2019 regarding the
performance of each Fund's underlying index, the correlation between each Fund's
performance and that of its underlying index, each Fund's tracking difference
and each Fund's excess return as compared to its benchmark index. The Board
noted that, effective April 8, 2016, each Fund changed its underlying index to
an index developed and maintained by Nasdaq, Inc. using the AlphaDEX(R) stock
selection methodology, and that the performance information included a blend of
the old and new indexes. The Board considered the Advisor's explanations of how
the AlphaDEX(R) stock selection methodology impacts Fund performance in various
market environments, and the Advisor's statement that AlphaDEX(R) is designed to
provide long-term outperformance. Based on the information provided and its
ongoing review of performance, the Board concluded that each Fund was correlated
to its underlying index and that the tracking difference for each Fund was
within a reasonable range. In addition, the Board reviewed data prepared by
Broadridge comparing each Fund's performance to that of its respective
Performance Universe and to that of a broad-based benchmark index, but given
each Fund's objective of seeking investment results that correspond generally to
the performance of its underlying index, the Board placed more emphasis on its
review of correlation and tracking difference.

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

The Board considered information and discussed with the Advisor whether there
were any economies of scale in connection with providing advisory services to
the Funds and noted the Advisor's statement that it believes its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Funds. For the Unitary Fee Funds, the Board noted that any
reduction in fixed costs associated with the management of the Unitary Fee Funds
would benefit the Advisor, but that the unitary fee structure provides a level
of certainty in expenses for the Unitary Fee Funds. The Board considered the
revenues and allocated costs (including the allocation methodology) of the
Advisor in serving as investment advisor to each Fund for the twelve months
ended December 31, 2019 and the estimated profitability level for each 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 each Fund was
not unreasonable. In addition, the Board considered fall-out benefits described
by the Advisor that may be realized from its relationship with the Funds. The
Board considered that the Advisor had identified as a fall-out benefit to the

Advisor and FTP their exposure to investors and brokers who, absent their
exposure to the Funds, may have had no dealings with the Advisor or FTP, and
noted that the Advisor does not utilize soft dollars in connection with the
Funds. The Board concluded that the character and amount of potential fall-out
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 Agreements continue to be fair and reasonable and that the continuation
of the Agreements is in the best interests of each Fund. No single factor was
determinative in the Board's analysis.

                       LIQUIDITY RISK MANAGEMENT PROGRAM

In accordance with Rule 22e-4 under the Investment Company Act of 1940, as
amended (the "1940 Act"), the Funds and each other fund in the First Trust Fund
Complex, other than the closed-end funds, have adopted and implemented a
liquidity risk management program (the "Program") reasonably designed to assess
and manage the funds' liquidity risk, i.e., the risk that a fund could not meet
requests to redeem shares issued by the fund without significant dilution of
remaining investors' interests in the fund. The Board of Trustees of the First
Trust Funds has appointed First Trust Advisors, L.P. (the "Advisor") as the
person designated to administer the Program, and in this capacity the Advisor
performs its duties primarily through the activities and efforts of the First
Trust Liquidity Committee.

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,
including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind.

At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4
and the Program, the Advisor provided the Board with a written report prepared
by the Advisor that addressed the operation of the Program during the period
from June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund that is required under the Program to have one, and any material
changes to the Program. Note that because the Funds primarily hold assets that
are highly liquid investments, the Funds have not adopted a highly liquid
investment minimum.

As stated in the written report, during the review period, no fund breached the
15% limitation on illiquid investments, no fund with a highly liquid investment
minimum breached that minimum and no fund filed a Form N-LIQUID. The Advisor
concluded that each fund's investment strategy is appropriate for an open-end
fund; that the Program operated effectively in all material respects during the
review period; and that the Program is reasonably designed to assess and manage
the liquidity risk of each fund and to maintain compliance with Rule 22e-4.


                                                                        Page 135

      instructions.

(e)   Not applicable.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

      (a) Audit Fees (Registrant) -- The aggregate fees billed for each of the
last two fiscal years for professional services rendered by the principal
accountant for the audit of the registrant's annual financial statements or
services that are normally provided by the accountant in connection with
statutory and regulatory filings or engagements were $420,000 for 2019 and
$399,000 for 2020.

      (b) Audit-Related Fees (Registrant) -- The aggregate fees billed in each
of the last two fiscal years for assurance and related services by the principal
accountant that are reasonably related to the performance of the audit of the
registrant's financial statements and are not reported under paragraph (a) of
this Item were $0 for 2019 and $0 for 2020.

      Audit-Related Fees (Investment Adviser and Distributor) -- The aggregate
fees billed in each of the last two fiscal years for assurance and related
services by the principal accountant that are reasonably related to the
performance of the audit of the registrant's financial statements and are not
reported under paragraph (a) of this Item were $0 for 2019 and $0 for 2020.

      (c) Tax Fees (Registrant) -- The aggregate fees billed in each of the last

      All Other Fees (Investment Adviser and Distributor) -- The aggregate fees
billed in each of the last two fiscal years for products and services provided
by the principal accountant to the registrant's investment adviser and
distributor, other than the services reported in paragraphs (a) through (c) of
this Item were $0 for 2018 and $0 for 2019 for the Adviser and $0 for 2019 and

      (e)(1) Disclose the audit committee's pre-approval policies and procedures
described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

      Pursuant to its charter and its Audit and Non-Audit Services Pre-Approval
Policy, the Audit Committee (the "Committee") is responsible for the
pre-approval of all audit services and permitted non-audit services (including
the fees and terms thereof) to be performed for the registrant by its
independent auditors. The Chairman of the Committee is authorized to give such
pre-approvals on behalf of the Committee up to $25,000 and report any such
pre-approval to the full Committee.

      The Committee is also responsible for the pre-approval of the independent
auditor's engagements for non-audit services with the registrant's adviser (not
including a sub-adviser whose role is primarily portfolio management and is
sub-contracted or overseen by another investment adviser) and any entity
controlling, controlled by or under common control with the investment adviser
that provides ongoing services to the registrant, if the engagement relates
directly to the operations and financial reporting of the registrant, subject to
the de minimis exceptions for non-audit services described in Rule 2-01 of
Regulation S-X. If the independent auditor has provided non-audit services to
the registrant's adviser (other than any sub-adviser whose role is primarily
portfolio management and is sub-contracted with or overseen by another
investment adviser) and any entity controlling, controlled by or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to its policies, the Committee
will consider whether the provision of such non-audit services is compatible
with the auditor's independence.

      (e)(2) The percentage of services described in each of paragraphs (b)
through (d) for the registrant and the registrant's investment adviser and
distributor of this Item that were approved by the audit committee pursuant to
the pre-approval exceptions included in paragraph (c)(7)(i)(C) or
paragraph(C)(7)(ii) of Rule 2-01 of Regulation S-X are as follows:

           Registrant:              Adviser and Distributor:
           -----------              ------------------------
             (b) 0%                          (b) 0%
             (c) 0%                          (c) 0%
             (d) 0%                          (d) 0%

      (f) The percentage of hours expended on the principal accountant's
engagement to audit the registrant's financial statements for the most recent
fiscal year that were attributed to work performed by persons other than the
principal accountant's full-time, permanent employees was less than fifty
percent.

      (g) The aggregate non-audit fees billed by the registrant's accountant for
services rendered to the registrant, and rendered to the registrant's investment
adviser (not including any sub-adviser whose role is primarily portfolio
management and is subcontracted with or overseen by another investment adviser),
and any entity controlling, controlled by, or under common control with the
adviser that provides ongoing services to the registrant for 2019 were $61,425
for the registrant, $33,300 for the registrant's investment adviser and $46,000
for the registrant's distributor, and for 2020 were $62,950 for the registrant,
$47,170 for the registrant's investment adviser and $70,330 for the registrant's
distributor.

      (h) The registrant's audit committee of its Board of Trustees has
determined that the provision of non-audit services that were rendered to the
registrant's investment adviser (not including any sub-adviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X is compatible with maintaining the principal accountant's
independence.
