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.

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 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 of investing in the Funds.

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

The Advisor may also periodically provide additional information on Fund performance on each Fund's webpage at www.ftportfolios.com.

SHAREHOLDER LETTER

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

Dear Shareholders:

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

We are now two decades into this millennium and while it has clearly not been smooth sailing for the securities markets or the economy, it has been relatively prosperous for those investors willing to stay the course. We have always been a proponent of buy-and-hold investing and believe in the merits of investing for the long haul, including the implementation of such basic strategies as diversification and asset allocation.

From December 31, 1999 through December 31, 2019, the S&P 500(R) Index posted an average annual total return of 6.05%, according to Bloomberg. Over that same period, the ICE BofA 7-10 Year U.S. Treasury Index generated an average annual total return of 5.56%. These two asset classes are positioned at opposite ends of the risk spectrum. Historically speaking, stocks have tended to outperform government bonds in the U.S. by close to a 2 to 1 annual margin. For comparative purposes, from 1926 through 2019, the S&P 500(R) Index posted an average annual total return of 10.20%, compared to 5.56% for long-term government bonds, according to Morningstar/Ibbotson Associates. The returns from this millennium show that the S&P 500(R) Index lagged its historical average by more than four percentage points per year, while government bonds performed in line with their average. Remember, investors endured two severe bear markets in stocks between 2000 and 2009. This is one of the reasons we believe that, despite the S&P
500(R) Index setting new highs, equities are currently undervalued.

Over the six-month period ended January 31, 2020, the S&P 500(R) Index was up 9.31% on a total return basis, which is a strong showing for just half a year. The two top-performing sectors by far were Information Technology and Utilities, according to Bloomberg. These two sectors make for an interesting pair in that one is growth-oriented, while the other is more defensive in nature, with a better than average dividend yield. The combination of the strength of the U.S. labor market, short-term interest rates and U.S. Treasury yields hovering around 1.50% to 2.00%, as of January 31, 2020, relatively modest inflation with the Consumer Price Index at 2.50% on a trailing 12-month basis and a favorable U.S. corporate tax structure helps foster a climate of opportunity for investors, in our opinion. We continue to urge investors to stay the course.

One caveat moving forward is the outbreak of the respiratory disease designated as COVID-19 that has caused significant volatility and declines in global financial markets which have caused losses for investors. The impact of this COVID-19 pandemic may be short term or may last for an extended period of time and in either case could result in a substantial downturn or recession. We are continuing to monitor these events.

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.

MARKET OVERVIEW

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
SEMI-ANNUAL REPORT
JANUARY 31, 2020

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

The Trump Administration's efforts to persuade some of the U.S.'s most important economic partners to renegotiate standing trade agreements began in earnest in March 2018, when President Donald J. Trump initiated the first round of tariffs on imported steel and aluminum. This somewhat heavy-handed approach has been operational for 22 months and counting. Some progress, however, has been made. The U.S. and China signed "Phase One" of a broader trade pact on January 15, 2020. President Trump signed the United States-Mexico-Canada Agreement into law on January 29, 2020, which updated the North American Free Trade Agreement. Progress notwithstanding, we believe that the ongoing trade conflict, particularly with China, has negatively impacted economic growth rates in the U.S. to such an extent that the Federal Reserve (the "Fed") felt compelled to intercede in the matter.

Six months ago, the Fed chose to reverse course with respect to its monetary policy. President Trump had been urging the Fed to cut rates for some time. For those who may not follow the Fed closely, after holding its federal funds target rate (upper bound) at an artificially low 0.25% for seven years (December 2008-December 2015) to help stimulate U.S. economic activity, the Fed spent the better part of the next four years (December 2015-July 2019) increasing its benchmark lending rate in an effort to normalize it. Over that period, the Fed increased the rate from 0.25% to 2.50%. To lend some perspective, the average federal funds target rate (upper bound) was 2.93% for the 30-year period ended January 31, 2020, so the Fed came close to achieving its goal of normalizing it, according to data from Bloomberg. From the end of July 2019 through the end of November 2019, however, the Fed initiated three rate cuts that dropped it from 2.50% to 1.75%, where it still stands.

As previously noted, one of the by-products of the escalation in the use of tariffs by all parties involved has been a slowdown in economic growth, particularly in the U.S. The annualized U.S. real gross domestic product ("GDP") growth rate in the second quarter of 2018 (when new tariffs were introduced) was 3.5%. In 2019, the first, second, third and fourth quarters generated annualized GDP growth rates of 3.1%, 2.0%, 2.1% and 2.1%, respectively, according to data from the Bureau of Economic Analysis. The past three quarters fell below the 2.3% average for the current U.S. economic recovery, which has run from July 2009 to the present, according to the National Bureau of Economic Research. The silver lining in this story, in our opinion, is that the stock and bond markets have continued to perform well despite the slowdown in economic activity.

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 $6.37 trillion in January 2020, up from $5.16 trillion a year ago, according to its own release. Total assets of U.S. listed ETFs/ETPs stood at an all-time high of $4.44 trillion, up from $3.63 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 January 31, 2020, U.S. Equity funds/ETFs reported estimated net outflows totaling $58.71 billion, according to data from Morningstar. As has been the case in recent years, investors favored passive funds over actively managed funds. Passive U.S. Equity funds/ETFs reported estimated net inflows totaling $175.19 billion, compared to estimated net outflows totaling $233.90 billion for actively managed U.S. Equity funds/ETFs.

In our view, investors have shied away from Sector funds and ETFs over the past year. For the 12-month period ended January 31, 2020, Sector Equity funds/ETFs reported estimated net outflows totaling $19.85 billion. Passive Sector Equity funds/ETFs, however, reported estimated net inflows totaling $9.06 billion, compared to estimated net outflows totaling $28.91 billion for actively managed Sector Equity funds/ETFs.

For the six-month period ended January 31, 2020, 10 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 9.31% over the period. Three of the 11 sectors outperformed the broader index during the same period. Those three sectors were Information Technology (+18.95%), Utilities (+17.82%) and Health Care (+10.52%), according to Bloomberg. The sector that posted the lone negative total return for the same period was Energy, which was down 10.51%.

One caveat moving forward is the outbreak of the respiratory disease designated as COVID-19 that has caused significant volatility and declines in global financial markets which have caused losses for investors. The impact of this COVID-19 pandemic may be short term or may last for an extended period of time and in either case could result in a substantial downturn or recession. We are continuing to monitor these events.

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 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 Russell Global Sectors (the "RGS") sector scheme to determine a stock's sector membership.

(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 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 JANUARY 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, 2014 through January 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 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 RGS sector scheme to determine a stock's sector membership.

(1) On or about September 18, 2 008, 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 JANUARY 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, 2014 through January 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 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 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 RGS 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 JANUARY 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, 2014 through January 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 common stocks 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 RGS 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) Financial Services 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.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV AS OF JANUARY 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, 2014 through January 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 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 RGS 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) 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 JANUARY 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, 2014 through January 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 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 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 RGS 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) 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 JANUARY 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, 2014 through January 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 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 RGS 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) 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 JANUARY 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, 2014 through January 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 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 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 RGS 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) 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 JANUARY 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, 2014 through January 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 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 RGS 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 JANUARY 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, 2014 through January 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. 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.

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

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

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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

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 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.

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 January 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 January 31, 2020, all the Funds except FXG, FXN and FXH had securities in the securities lending program. During the six months ended January 31, 2020, all the Funds except for FXG 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 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 six months ended January 31, 2020, were received as collateral for lending securities.

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, 2019 was as follows:

                                                           Distributions paid from  Distributions paid from  Distributions paid from

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 2016, 2017, 2018, and 2019 remain open to federal and state audit. As of January 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.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"), net capital losses arising in taxable years beginning after December 22, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for up to eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses. At July 31, 2019, the Funds had post-enactment net capital losses for federal income tax purposes as shown in the following table. 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 Fund shareholders. The Funds are 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.

                                                              Post-Enactment -

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

Page 63


NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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

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, 2020.

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 six months ended January 31, 2020, there were no fees waived or expenses reimbursed by First Trust for the Funds. As of January 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.

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.

4. PURCHASES AND SALES OF SECURITIES

For the six months ended January 31, 2020, the cost of purchases and proceeds from sales of investments for each Fund, excluding short-term investments and in-kind transactions, were as follows:

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, 2020.

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.

PROXY VOTING POLICIES AND PROCEDURES

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

PORTFOLIO HOLDINGS

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

RISK CONSIDERATIONS

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

CONCENTRATION RISK. To the extent that a fund is able to invest a 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.

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 impact of this COVID-19 pandemic may be short term or may last for an extended period of time, and in either case could result in a substantial economic downturn or recession.

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.

PERFORMANCE AND RISK DISCLOSURE

There is no assurance that any Fund described in this report will achieve its investment objective.

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 be worth more or less than their original cost.

The Advisor may also periodically provide additional information on Fund performance on each Fund's webpage at www.ftportfolios.com.

SHAREHOLDER LETTER

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

Dear Shareholders:

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

We are now two decades into this millennium and while it has clearly not been smooth sailing for the securities markets or the economy, it has been relatively prosperous for those investors willing to stay the course. We have always been a proponent of buy-and-hold investing and believe in the merits of investing for the long haul, including the implementation of such basic strategies as diversification and asset allocation.

From December 31, 1999 through December 31, 2019, the S&P 500(R) Index posted an average annual total return of 6.05%, according to Bloomberg. Over that same period, the ICE BofA 7-10 Year U.S. Treasury Index generated an average annual total return of 5.56%. These two asset classes are positioned at opposite ends of the risk spectrum. Historically speaking, stocks have tended to outperform government bonds in the U.S. by close to a 2 to 1 annual margin. For comparative purposes, from 1926 through 2019, the S&P 500(R) Index posted an average annual total return of 10.20%, compared to 5.56% for long-term government bonds, according to Morningstar/Ibbotson Associates. The returns from this millennium show that the S&P 500(R) Index lagged its historical average by more than four percentage points per year, while government bonds performed in line with their average. Remember, investors endured two severe bear markets in stocks between 2000 and 2009. This is one of the reasons we believe that, despite the S&P
500(R) Index setting new highs, equities are currently undervalued.

Over the six-month period ended January 31, 2020, the S&P 500(R) Index was up 9.31% on a total return basis, which is a strong showing for just half a year. The two top-performing sectors by far were Information Technology and Utilities, according to Bloomberg. These two sectors make for an interesting pair in that one is growth-oriented, while the other is more defensive in nature, with a better than average dividend yield. The combination of the strength of the U.S. labor market, short-term interest rates and U.S. Treasury yields hovering around 1.50% to 2.00%, as of January 31, 2020, relatively modest inflation with the Consumer Price Index at 2.50% on a trailing 12-month basis and a favorable U.S. corporate tax structure helps foster a climate of opportunity for investors, in our opinion. We continue to urge investors to stay the course.

One caveat moving forward is the outbreak of the respiratory disease designated as COVID-19 that has caused significant volatility and declines in global financial markets which have caused losses for investors. The impact of this COVID-19 pandemic may be short term or may last for an extended period of time and in either case could result in a substantial downturn or recession. We are continuing to monitor these events.

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

Chief Executive Officer of First Trust Advisors L.P.

MARKET OVERVIEW

FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND
SEMI-ANNUAL REPORT
JANUARY 31, 2020

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./GLOBAL ECONOMY

The Trump Administration's efforts to persuade some of the U.S.'s most important economic partners to renegotiate standing trade agreements began in earnest in March 2018, when President Donald J. Trump initiated the first round of tariffs on imported steel and aluminum. This somewhat heavy-handed approach has been operational for 22 months and counting. Some progress, however, has been made. The U.S. and China signed the first phase of a broader trade pact on January 15, 2020. President Trump signed the United States-Mexico-Canada Agreement into law on January 29, 2020, which updated the North American Free Trade Agreement. Progress notwithstanding, we believe that the ongoing trade conflict, particularly with China, has negatively impacted economic growth rates in the U.S. to such an extent that the Federal Reserve (the "Fed") felt compelled to intercede in the matter.

Six months ago, the Fed chose to reverse course with respect to its monetary policy. President Trump had been urging the Fed to cut rates for some time. For those who may not follow the Fed closely, after holding its federal funds target rate (upper bound) at an artificially low 0.25% for seven years (December 2008-December 2015) to help stimulate U.S. economic activity, the Fed spent the better part of the next four years (December 2015-July 2019) increasing its benchmark lending rate in an effort to normalize it. Over that period, the Fed increased the rate from 0.25% to 2.50%. To lend some perspective, the average federal funds target rate (upper bound) was 2.93% for the 30-year period ended January 31, 2020, so the Fed came close to achieving its goal of normalizing it, according to data from Bloomberg. From the end of July 2019 through the end of November 2019, however, the Fed initiated three rate cuts that dropped it from 2.50% to 1.75%, where it still stands.

As previously noted, one of the by-products of the escalation in the use of tariffs by all parties involved has been a slowdown in economic growth, particularly in the U.S. The annualized U.S. real gross domestic product ("GDP") growth rate in the second quarter of 2018 (when new tariffs were introduced) was 3.5%. In 2019, the first, second, third and fourth quarters generated annualized GDP growth rates of 3.1%, 2.0%, 2.1% and 2.1%, respectively, according to data from the Bureau of Economic Analysis. The past three quarters fell below the 2.3% average for the current U.S. economic recovery, which has run from July 2009 to the present, according to the National Bureau of Economic Research. The silver lining in this story, in our opinion, is that the stock and bond markets have continued to perform well despite the slowdown in economic activity.

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 $6.37 trillion in January 2020, up from $5.16 trillion a year ago, according to its own release. Total assets of U.S. listed ETFs/ETPs stood at an all-time high of $4.44 trillion for the same period, up from $3.63 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 January 31, 2020, U.S. Equity funds/ETFs reported estimated net outflows totaling $58.71 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 $175.19 billion, compared to estimated net outflows totaling $233.90 billion for actively managed U.S. Equity funds/ETFs for the same period.

For the 12-month period ended January 31, 2020, U.S. Large Blend, U.S. Large Growth and U.S. Large Value equity funds/ETFs reported estimated net flows totaling $116.55 billion, -$70.74 billion and -$14.96 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 -$2.16 billion, -$10.49 billion and -$16.15 billion, respectively, for the same period. U.S. Small Blend, U.S. Small Growth and U.S. Small Value equity funds/ETFs reported estimated net flows totaling -$8.16 billion, -$7.64 billion and -$2.99 billion, respectively, for the same period. The only style/market cap that reported net inflows for the 12-month period ended January 31, 2020 was Large-Cap Blend.

For the six-month period ended January 31, 2020, the S&P 500(R) Index posted a total return of 9.31%, according to Bloomberg. Growth stocks outperformed value stocks for the same period. The S&P 500(R) Growth Index posted a total return of 10.30%, compared to 8.16% for the S&P 500(R) Value Index, for the same period. The S&P MidCap 400(R) Index posted a total return of 2.95% for the same period. Growth stocks outperformed value stocks during the period. The S&P MidCap 400(R) Growth Index posted a total return of 3.50%, compared to 2.28% for the S&P MidCap 400(R) Value Index, during the period. The S&P SmallCap 600(R) Index posted a total return of 2.54% for the same period. Growth stocks outperformed value stocks for the same period. The S&P SmallCap 600(R) Growth Index posted a total return of 3.74%, compared to 1.18% for the S&P SmallCap 600(R) Value Index, for the same period.

One caveat moving forward is the outbreak of the respiratory disease designated as COVID-19 that has caused significant volatility and declines in global financial markets which have caused losses for investors. The impact of this COVID-19 pandemic may be short term or may last for an extended period of time and in either case could result in a substantial downturn or recession. We are continuing to monitor these events.

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 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.

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 JANUARY 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, 2014 through January 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 MID CAP CORE ALPHADEX(R) FUND (FNX)

The First Trust Mid 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) Mid Cap Core Index (the "Index"). The Fund will normally invest at least 90% of its net assets (including investment borrowings) in 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 "FNX."

The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select stocks from the Nasdaq US 600 Mid 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.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)

FIRST TRUST SMALL CAP CORE ALPHADEX(R) FUND (FYX)

The First Trust Small 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) Small Cap Core Index (the "Index"). The Fund will normally invest at least 90% of its net assets (including investment borrowings) in 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 "FYX."

The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select stocks from the Nasdaq US 700 Small 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.

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 JANUARY 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, 2014 through January 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 JANUARY 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, 2014 through January 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 LARGE CAP GROWTH ALPHADEX(R) FUND (FTC)

The First Trust Large Cap Growth 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 Growth Index (the "Index"). The Fund will normally invest at least 90% of its net assets (including investment borrowings) in 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 "FTC."

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 Growth 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.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)

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 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 Index, Nasdaq US 600 Mid Cap Index, and Nasdaq US 700 Small Cap 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 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 JANUARY 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, 2014 through January 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 JANUARY 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, 2014 through January 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 MID CAP VALUE ALPHADEX(R) FUND (FNK)

The First Trust Mid 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) Mid Cap Value Index (the "Index"). The Fund will normally invest at least 90% of its net assets (including investment borrowings) in 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 "FNK."

The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select stocks from the Nasdaq US 600 Mid 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 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.

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, 2014 through January 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 MID CAP GROWTH ALPHADEX(R) FUND (FNY)

The First Trust Mid Cap Growth 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) Mid Cap Growth Index (the "Index"). The Fund will normally invest at least 90% of its net assets (including investment borrowings) in 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 "FNY."

The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select stocks from the Nasdaq US 600 Mid Cap Growth 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.

FUND PERFORMANCE OVERVIEW (UNAUDITED) (CONTINUED)

FIRST TRUST SMALL CAP VALUE ALPHADEX(R) FUND (FYT)

The First Trust Small 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) Small Cap Value Index (the "Index"). The Fund will normally invest at least 90% of its net assets (including investment borrowings) in 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 "FYT."

The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select stocks from the Nasdaq US 700 Small Cap Value Index which 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 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 JANUARY 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, 2014 through January 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 JANUARY 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, 2014 through January 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 MEGA CAP ALPHADEX(R) FUND (FMK)

The First Trust Mega Cap 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) Mega Cap Index (the "Index"). The Fund will normally invest at least 90% of its net assets (including investment borrowings) in 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 "FMK."

The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select mega cap 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.

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
JANUARY 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 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 January 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
STYLE FUNDS
JANUARY 31, 2020 (UNAUDITED)

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 Mid Cap Growth AlphaDEX(R) Fund - (ticker "FNY") First Trust Small Cap Value AlphaDEX(R) Fund - (ticker "FYT") 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." 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.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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

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 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.

JANUARY 31, 2020 (UNAUDITED)

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 January 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 dividend and interest earned on the securities loaned is accounted for in the

same manner as other dividend and interest income. At January 31, 2020, all the Funds except FTA, FTC and FMK had securities in the securities lending program. During the six months ended January 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 six months ended January 31, 2020, were received as collateral for lending securities.

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, 2019, was as follows:

                                                           Distributions paid from  Distributions paid from  Distributions paid from

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 2016, 2017, 2018, and 2019 remain open to federal and state audit. As of January 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.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"), net capital losses arising in taxable years beginning after December 22, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for up to eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses. At July 31, 2019, the Funds had post-enactment net capital losses for federal income tax purposes as shown in the following table. 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 Fund shareholders. The Funds are 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.

                                                              Post-Enactment -

H. EXPENSES

Expenses that are directly related to one of the Funds are charged directly to the respective Fund, except for the 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 "Unitary Fee Funds"), for which expenses other than excluded expenses (discussed in Note 3) are paid by the Advisor. General expenses of the Trust are allocated to all the Funds based upon the net assets of each Fund.

First Trust Portfolios L.P. ("FTP") has entered into licensing agreements with Nasdaq, Inc. for each of the Style Funds. The license agreements allow for the use by FTP of certain trademarks and trade names. The Funds and First Trust are sub-licensees to the applicable license agreement. The Funds, except for the Unitary Fee Funds, are required to pay licensing fees, which are shown on the Statements of Operations. The licensing fees for the Unitary Fee Funds are paid by First Trust from the unitary investment advisory fees it receives from each of these Funds.

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, 2020.

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 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.

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, 2020.

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 will be held. 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. Holders of shares of FMK purchased after the record date set for the special meeting of shareholders will not be entitled to vote those shares at the special meeting.

PROXY VOTING POLICIES AND PROCEDURES

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

PORTFOLIO HOLDINGS

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

RISK CONSIDERATIONS

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

CONCENTRATION RISK. To the extent that a fund is able to invest a 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.

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 impact of this COVID-19 pandemic may be short term or may last for an extended period of time, and in either case could result in a substantial economic downturn or recession.

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.
