Forward-looking statements include statements regarding the goals, beliefs, plans or current expectations of First Trust Advisors L.P. ("First Trust" or the "Advisor") and its representatives, taking into account the information currently available to them. Forward-looking statements include all statements that do not relate solely to current or historical fact. For example, forward-looking statements include the use of words such as "anticipate," "estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or other words that convey uncertainty of future events or outcomes. Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of any series of First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust") described in this report (each such series is referred to as a "Fund" and collectively, as the "Funds") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and its representatives only as of the date hereof. We undertake no obligation to publicly revise or update these forward-looking statements to reflect events and circumstances that arise after the date hereof. PERFORMANCE AND RISK DISCLOSURE There is no assurance that any Fund described in this report will achieve its investment objective. Each Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund 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.

Page 1 -------------------------------------------------------------------------------- SHAREHOLDER LETTER -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND ANNUAL LETTER FROM THE CHAIRMAN AND CEO JULY 31, 2019 Dear Shareholders: One thing we can all agree on and expect: headline news coming out of Washington, DC continues to influence the financial markets. By late February of 2019, President Trump announced the U.S. was close to a trade deal with China, yet by May 10, existing tariffs on Chinese imports jumped from 10% to 25%. Furthermore, the President's threat of additional tariffs on the remaining $300 billion in Chinese imports became a reality with his announcement after a Federal Funds rate cut of 0.25% on the last day of July. This led many to wonder if these events could be signaling a recession. While reticent investors sought cover in "risk-on" assets, calendar year-to-date performances of broad markets as of July 31, 2019, were strong. Both U.S. and world equities, as indicated by the S&P 500(R) Index and the MSCI All Country World Index, returned 20.24% and 16.57%, respectively. Bonds, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index, returned 6.35%, for the same period. Despite the ongoing bluster of the news cycle, we believe the economy is doing well and productivity growth, due to deregulation and lower taxes on corporate profits, has improved over the last two years. o The Consumer Confidence Index of 135.7 for July is strong and at the highest level this year. o The U.S. inflation rate hovers near 2%, on average, as it has for the last decade. o July's unemployment rate of 3.7% barely moved from 3.6% in May, which was the lowest level since December of 1969. Before you head for the exits or reach for the antacids due to the latest political equivocation, keep a balanced perspective in view. Remember, no one can predict the inevitable and expected market fluctuations. Speak periodically with your investment professional, who can provide insight when it comes to investing and discovering opportunities when they arise. Thank you for giving First Trust the opportunity to be a part of your financial plan. We value our relationship with you. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 2 -------------------------------------------------------------------------------- MARKET OVERVIEW -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND ANNUAL REPORT JULY 31, 2019 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 25 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 trade conflict between the U.S. and China was nearly 17-months-old at the close of July 2019. In our opinion, the most notable change from the business climate of 2018 to that of 2019 was the Trump Administration's ratcheting up of tariffs on roughly $200 billion of imported goods from China. On May 10, 2019, tariffs jumped from 10% to 25%. At the end of July, President Trump decided to up the ante on China by announcing a 10% tariff on the remaining $300 billion or so in goods shipped to the U.S. annually. The Trump Administration tends to play the tariff card whenever trade negotiations get bogged down. The tariff was to begin on September 1, 2019. We learned in August, however, that President Trump softened his stance by shielding some consumer products from the new tariff until at least December in order to allow retailers to stock their inventories for the critical holiday shopping season. The ongoing dispute has become a drag on global growth, according to organizations such as the International Monetary Fund. While the U.S. economy continues to flourish relative to many other developed and emerging economies, recent data suggests that China's economy is being stressed by the tariffs. China's gross domestic product rose at an annualized pace of 6.2% in the second quarter of 2019, the slowest rate of growth in 27 years, according to MarketWatch. CNBC reported that, as of July 1, 2019, the current U.S. economic expansion will become the longest in its history, breaking the previous record of 120 months of growth from March 1991 to March 2001, according to data from the National Bureau of Economic Research. The recent escalation in the trade conflict between the U.S. and China has investors flocking to safe-haven assets around the globe, including bonds. One reflection of this is the market value of the Bloomberg Barclays Global Negative Yielding Debt Index, which closed the July 31, 2019 trading session at $14.01 trillion, according to Bloomberg. Another is the plunge in the yield on the benchmark 10-year Treasury Note, which declined by 94 basis points to 2.02% over the past 12 months. More than half of that drop transpired after mid-April 2019. 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 $5.74 trillion in July 2019, up from $5.12 trillion a year ago, according to its own release. Total assets of U.S. listed ETFs/ETPs also stood at an all-time high of $4.02 trillion for the same period, 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 July 31, 2019, U.S. Equity funds/ETFs reported estimated net inflows totaling $40.68 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 $242.78 billion, compared to estimated net outflows totaling $202.10 billion for actively managed U.S. Equity funds/ETFs, for the same period. Investors shied away from sector funds and sector ETFs. For the 12-month period ended July 31, 2019, Sector Equity funds/ETFs reported estimated net outflows totaling $50.79 billion. Passive Sector Equity funds/ETFs reported estimated net outflows totaling $20.18 billion, compared to estimated net outflows totaling $30.61 billion for actively managed Sector Equity funds/ETFs for the same period. For the 12-month period ended July 31, 2019, nine of the 11 major sectors that comprise the S&P 500(R) Index generated positive total returns, according to Bloomberg. The S&P 500(R) Index posted a total return of 7.99% over the period. Six of the 11 sectors outperformed the broader index. Those six sectors were as follows: Real Estate (+17.56%); Utilities (+16.53%); Information Technology (+15.72%); Communication Services (+14.82%); Consumer Staples (+14.64%); and Consumer Discretionary (+9.22%), according to Bloomberg. The two sectors that posted negative total returns for the period were Materials, down 0.14%, and Energy, down 15.99%. Page 3 -------------------------------------------------------------------------------- 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.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXD's one-year net asset value ("NAV") return of 3.13% underperformed the S&P 500(R) Consumer Discretionary Index ("Benchmark") return of 9.22% by 6.09%. The Specialty Retail industry received the greatest allocation in the Fund during the period, with an average weight of 19.3%. This industry contributed 0.7% to the Fund's return. The greatest contributor to Fund performance was the Hotels, Restaurants, & Leisure industry. This industry received 14.6% allocation, performed 7.4% and contributed 1.8% to the Fund's overall return. The Auto Components industry was the greatest drag on the Fund, with a 6.1% weight, -26.6% return and -1.9% contribution to the Fund's return. The Fund underperformed the Benchmark during the period. The Hotels, Restaurants, & Leisure industry contributed the most to this underperformance. While the industry returned well in the Fund, the Benchmark gave this industry a slightly greater weight and received a much better return. In all, this industry contributed -3.4% to underperformance in the Fund versus the Benchmark. The greatest outperformance came from Internet & Direct Marketing Retail, which caused 0.7% outperformance for the Fund versus the Benchmark. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Consumer Discretionary 78.60% Communication Services 15.28 Industrials 2.50 Consumer Staples 1.97 Information Technology 1.65 ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Trade Desk (The), Inc., Class A 1.65% Qurate Retail, Inc., Series A 1.63 Roku, Inc. 1.63 Kohl's Corp. 1.62 Tempur Sealy International, Inc. 1.56 Gap (The), Inc. 1.55 Dick's Sporting Goods, Inc. 1.53 Macy's, Inc. 1.51 General Motors Co. 1.49 Urban Outfitters, Inc. 1.49 ------- Total 15.66% ======= ----------------------------- (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. The StrataQuant(R) Consumer Discretionary Index is a registered trademark of IDI and has been licensed for use by First Trust Portfolios L.P., which has sub-licensed the Index for use by the Fund. The Fund is not sponsored, endorsed, sold or promoted by IDI, and IDI makes no representation or warranty regarding the advisability of investing in the Fund or as to the result to be obtained by any person from use of the StrataQuant(R) Consumer Discretionary Index in connection with the trading of the Fund.

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund's past performance does not predict future performance. FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2019 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 July 31, 2019. 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.

Over the period, the Food Products industry was given the greatest allocation in the Fund with a weighting of 53.8%. With a return of 5.7% and contribution of 3.3% to the Fund's total return, this industry was the greatest positive contributor to the Fund's return. The Food & Staples Retailing industry caused the greatest drag in the portfolio, with a weight of 20.5%, return of -6.2%, and contribution to the Fund's return of -1.6%. The Fund underperformed the Benchmark during the period. The Household Products industry caused the most underperformance. The Benchmark allocated 22.3% to this industry, in contrast with the Fund's 10.2%, and these investments in the Benchmark returned 35%, while Household Products in the Fund returned 9.0%. In all, Household Products accounted for -4.3% underperformance in the Fund. The greatest outperformance for the Fund came simply by investing very little in the Tobacco industry. This industry was very nearly absent from the Fund, with an average allocation of only 0.5%, and earned 2.3% outperformance in the Fund versus the Benchmark. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Consumer Staples 100.00% ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Pilgrim's Pride Corp. 5.92% Casey's General Stores, Inc. 5.77 Archer-Daniels-Midland Co. 5.59 Walgreens Boots Alliance, Inc. 5.54 Kroger (The) Co. 5.41 Molson Coors Brewing Co., Class B 5.36 Hershey (The) Co. 4.31 Campbell Soup Co. 3.93 Constellation Brands, Inc., Class A 3.81 Tyson Foods, Inc., Class A 3.75 ------- Total 49.39% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

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.

The Oil, Gas, & Consumable Fuels industry was given by far the greatest allocation in the Fund and caused significant negative performance in the Fund. The allocation of 84.9% performed -36.3%, contributing -30.9% to the Fund's total return. The best-returning industry was the Chemicals industry, with a performance of -5.3%. With a meager 0.2% allocation, this industry contributed essentially nothing to the Fund's return (-2 basis points over the year). The Fund underperformed the Benchmark during the period. The heavily weighted Oil, Gas, & Consumable Fuels industry contributed -21% to this underperformance, while Energy Equipment & Services and Chemicals created 0.6% and 0.5% outperformance, respectively. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Energy 100.00% ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Phillips 66 5.48% HollyFrontier Corp. 5.38 Occidental Petroleum Corp. 5.11 Marathon Oil Corp. 4.95 ConocoPhillips 4.84 Cimarex Energy Co. 4.27 Antero Resources Corp. 4.17 Halliburton Co. 4.04 Marathon Petroleum Corp. 4.04 Murphy Oil Corp. 3.90 ------- Total 46.18% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

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.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXH's one-year NAV return of 1.07% underperformed the S&P 500(R) Health Care Index ("Benchmark") return of 4.29% by 3.22%. The industry receiving the greatest allocation was Health Care Providers and Services, with a 27.5% average weight over the period. This industry performed -3.3% and contributed -1.7% to the Fund's total performance. This -1.7% contribution was the greatest drag on the Fund's performance during the period. The greatest contributor to the Fund's performance was the Health Care Equipment and Supplies industry, with a 26.3% allocation, 10.2% performance and 2.5% contribution to the Fund's return. The Fund underperformed the Benchmark during the period. Investments in Health Care Technology garnered the most outperformance for the Fund. The Fund allocated 3.5% to this industry, while the Benchmark had only 0.6%, and this led to the Fund's outperformance of 1.8%. Meanwhile, investments in Health Care Equipment and Supplies caused -1.4% underperformance for the Fund. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Health Care 100.00% ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Universal Health Services, Inc., Class B 2.57% Mylan N.V. 2.44 DexCom, Inc. 2.32 Insulet Corp. 2.29 Veeva Systems, Inc., Class A 2.27 Biogen, Inc. 2.26 WellCare Health Plans, Inc. 2.24 STERIS PLC 2.22 Exelixis, Inc. 2.21 IQVIA Holdings, Inc. 2.20 ------- Total 23.02% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

The Machinery industry carried the most weight in the Fund during the period. With an average weight of 19.9% and a performance of -3.2%, this industry contributed -1.1% to the Fund's total return. The best industry for the Fund during this period was Commercial Services & Supplies, which received a 6.4% allocation, experienced 22.8% performance and contributed 2% to the Fund's total return. The worst drag on the Fund was from Trading Companies & Distributors. Investments in this industry accounted for -1.3% of the Fund's performance. The Fund outperformed the Benchmark during the period. The outperformance of 1.7% is attributable to investments in the Industrial Conglomerates industry, which was a drag on the Benchmark but was barely represented in the Fund. The greatest source of underperformance were the investments in the Machinery industry, which caused -1.5% underperformance against the Benchmark. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Industrials 86.80% Information Technology 11.56 Health Care 0.95 Materials 0.69 ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- CoStar Group, Inc. 2.05% Knight-Swift Transportation Holdings, Inc. 2.01 Northrop Grumman Corp. 1.97 Schneider National, Inc., Class B 1.95 Genpact Ltd. 1.92 FedEx Corp. 1.92 Booz Allen Hamilton Holding Corp. 1.92 Carlisle Cos., Inc. 1.90 HEICO Corp. 1.89 Air Lease Corp. 1.87 ------- Total 19.40% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund's past performance does not predict future performance. FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2019 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 July 31, 2019. 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. -------------------------------------------------------------------------------- NUMBER OF DAYS BID/ASK MIDPOINT AT/ABOVE NAV -------------------------------------------------------------------------------- FOR THE PERIOD 0.00%-0.49% 0.50%-0.99% 1.00%-1.99% >=2.00% 8/1/14 - 7/31/15 136 0 0 0 8/1/15 - 7/31/16 173 0 0 0 8/1/16 - 7/31/17 119 0 0 0 8/1/17 - 7/31/18 73 0 0 0 8/1/18 - 7/31/19 158 4 0 0 -------------------------------------------------------------------------------- NUMBER OF DAYS BID/ASK MIDPOINT BELOW NAV -------------------------------------------------------------------------------- FOR THE PERIOD 0.00%-0.49% 0.50%-0.99% 1.00%-1.99% >=2.00% 8/1/14 - 7/31/15 116 0 0 0 8/1/15 - 7/31/16 78 0 0 0 8/1/16 - 7/31/17 133 0 0 0 8/1/17 - 7/31/18 178 0 0 1 8/1/18 - 7/31/19 88 1 0 0 Page 21 -------------------------------------------------------------------------------- NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- Total returns for the period since inception are calculated from the inception date of each Fund. "Average Annual Total Returns" represent the average annual change in value of an investment over the periods indicated. "Cumulative Total Returns" represent the total change in value of an investment over the periods indicated. The total returns would have been lower if certain fees had not been waived and expenses reimbursed by the Advisor. Each Fund's per share net asset value ("NAV") is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return ("Market Price") is determined by using the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of each Fund did not trade in the secondary market until after the Fund's inception, for the period May 8, 2007 (inception) to May 10, 2007 (the first day of secondary market trading) the NAV of each Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in each Fund at NAV and Market Price, respectively. An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund's past performance is no guarantee of future performance. Page 22 FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS UNDERSTANDING YOUR FUND EXPENSES JULY 31, 2019 (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 July 31, 2019. 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.

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.

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:

(1) This index is developed, maintained and sponsored by ICE Data Indices, LLC or its affiliates ("IDI"), and licensed to First Trust Portfolios L.P. ("FTP"), the distributor of the Trust, by IDI. IDI is a successor-in-interest to previous entities that maintained the index in NYSE Group, Inc. and American Stock Exchange LLC. 2. SIGNIFICANT ACCOUNTING POLICIES The Funds are each considered an investment company and follow accounting and reporting guidance under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 946, "Financial Services-Investment Companies." The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. PORTFOLIO VALUATION Each Fund's NAV is determined daily as of the close of regular trading on the New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Each Fund's NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding. Each Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Funds' Page 57 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 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. Page 58 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund's investments as of July 31, 2019, is included with each Fund's Portfolio of Investments. B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income, if any, is recorded on the accrual basis. Withholding taxes and tax reclaims on foreign dividends have been provided for in accordance with each Fund's understanding of the applicable country's tax rules and rates. Distributions received from a Fund's investments in real estate investment trusts ("REITs") may be comprised of return of capital, capital gains and income. The actual character of the amounts received during the year is not known until after the REITs' fiscal year end. A Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by a Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude. C. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES Offsetting Assets and Liabilities require entities to disclose both gross and net information about instruments and transactions eligible for offset on the Statements of Assets and Liabilities, and disclose instruments and transactions subject to master netting or similar agreements. These disclosure requirements are intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on a fund's financial position. The transactions subject to offsetting disclosures are derivative instruments, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions. This disclosure, if applicable, is included within each Fund's Portfolio of Investments under the heading "Offsetting Assets and Liabilities." For financial reporting purposes, the Funds do not offset financial assets and financial liabilities that are subject to master netting arrangements ("MNAs") or similar agreements on the Statements of Assets and Liabilities. MNAs provide the right, in the event of default (including bankruptcy and insolvency), for the non-defaulting counterparty to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral. D. SECURITIES LENDING The Funds may lend securities representing up to 33 1/3% of the value of their total assets to broker-dealers, banks and other institutions to generate additional income. When a Fund loans its portfolio securities, it will receive, at the inception of each loan, collateral equal to at least 102% (for domestic securities) or 105% (for international securities) of the market value of the loaned securities. The collateral amount is valued at the beginning of each business day and is compared to the market value of the loaned securities from the prior business day to determine if additional collateral is required. If additional collateral is required, a request is sent to the borrower. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund's loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of (i) a decline in the value of the collateral provided for the loaned securities, (ii) a decline in the value of any investments made with cash collateral or (iii) an increase in the value of the loaned securities if the borrower does not increase the collateral accordingly and the borrower fails to return the securities. These events could also trigger adverse tax consequences for the Funds. Under the Funds' Securities Lending Agency Agreement, the securities lending agent will generally bear the risk that a borrower may default on its obligation to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the Funds' securities lending agent and is responsible for executing the lending of the portfolio securities to creditworthy borrowers. The Funds, however, will be responsible for the risks associated with the investment of cash collateral. A Fund may lose money on its investment of cash collateral, which may affect its ability to repay the collateral to the borrower without the use of other Fund assets. Each Fund that engages in securities lending receives compensation (net of any rebate and securities lending agent fees) for lending its securities. Compensation can be in the form of fees received from the securities lending agent or dividends or interest earned from the investment of cash collateral. The fees received from the securities lending agent are accrued daily. The dividend and interest earned on the securities loaned is accounted for in the same manner as other dividend and interest income. At July 31, 2019, only FXN and FXR had securities in the securities lending program. During the fiscal year ended July 31, 2019, all the Funds participated in the securities lending program. In the event of a default by a borrower with respect to any loan, BBH will exercise any and all remedies provided under the applicable borrower agreement to make the Funds whole. These remedies include purchasing replacement securities by applying the collateral held from the defaulting broker against the purchase cost of the replacement securities. If, despite such efforts by BBH to exercise these remedies, a Fund sustains losses as a result of a borrower's default, BBH will indemnify the Fund by purchasing replacement securities at its own expense, or paying the Fund an amount equal to the market value of the replacement securities, subject to certain limitations which are set forth in detail in the Securities Lending Agency Agreement between the Trust on behalf of the Funds and BBH. Page 59 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 E. REPURCHASE AGREEMENTS Repurchase agreements involve the purchase of securities subject to the seller's agreement to repurchase the securities at a mutually agreed upon date and price, under the terms of a Master Repurchase Agreement ("MRA"). During the term of a repurchase agreement, the value of the underlying securities held as collateral on behalf of a Fund, including accrued interest, is required to exceed the value of the repurchase agreement, including accrued interest. The underlying securities for all repurchase agreements are held at the Funds' custodian or designated sub-custodians under tri-party repurchase agreements. MRAs govern transactions between a Fund and select counterparties. The MRAs maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for repurchase agreements. Repurchase agreements received for lending securities are collateralized by U.S. Treasury securities. The U.S. Treasury securities are held in a joint custody account at BBH on behalf of the Funds participating in the securities lending program. In the event the counterparty defaults on the repurchase agreement, the U.S. Treasury securities can either be maintained as part of a Fund's portfolio or sold for cash. A Fund could suffer a loss to the extent that the proceeds from the sale of the underlying collateral held by the Fund are less than the repurchase price and the Fund's costs associated with the delay and enforcement of the MRA. While the Funds may invest in repurchase agreements, any repurchase agreements held by the Funds during the fiscal year ended July 31, 2019, 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:

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 July 31, 2019, 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.

Page 61 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended July 31, 2019, the following Fund listed below incurred and elected to defer net late year ordinary or capital losses as follows:

Qualified Late Year Losses -------------------------- Ordinary Losses Capital Losses --------------- -------------- First Trust Health Care AlphaDEX(R) Fund $ 889,570 $ --

In order to present paid-in capital and accumulated distributable earnings (loss) (which consists of accumulated net investment income (loss), accumulated net realized gain (loss) on investments and net unrealized appreciation (depreciation) on investments) on the Statements of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to paid-in capital, accumulated net investment income (loss) and accumulated net realized gain (loss) on investments. These adjustments are primarily due to the difference between book and tax treatments of income and gains on various investment securities held by the Funds and in-kind transactions. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended July 31, 2019, the adjustments for each Fund were as follows:

H. EXPENSES Expenses that are directly related to one of the Funds are charged directly to the respective Fund. General expenses of the Trust are allocated to all the Funds based upon the net assets of each Fund. FTP has entered into licensing agreements with IDI for each of the Funds. The license agreements allow for the use by FTP of certain trademarks and trade names of IDI. The Funds and First Trust are sub-licensees to the license agreement. The Funds are required to pay licensing fees, which are shown on the Statements of Operations. I. NEW ACCOUNTING PRONOUNCEMENT On August 28, 2018, the FASB issued Accounting Standards Update ("ASU") 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," which amends the fair value measurement disclosure requirements of ASC 820. The amendments of ASU 2018-13 include new, eliminated, and modified disclosure requirements of ASC 820. In addition, the amendments clarify that materiality is an appropriate consideration of entities when evaluating disclosure requirements. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Funds have early adopted ASU 2018-13 for these financial statements, which did not result in a material impact. 3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS First Trust, the investment advisor to the Funds, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the selection and ongoing monitoring of the securities in each Fund's portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Funds. For these services, First Trust is paid an annual management fee of 0.50% of each Fund's average daily net assets. The Trust and First Trust have entered into an Expense Reimbursement, Fee Waiver and Recovery Agreement ("Recovery Agreement") in which First Trust has agreed to waive fees and/or reimburse Fund expenses to the extent that the operating expenses of each Fund (excluding interest expense, brokerage commissions and other trading expenses, acquired Page 62 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 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 its Expense Cap. These amounts would be included in "Expenses previously waived or reimbursed" on the Statements of Operations. For the fiscal year ended July 31, 2019, there were no fees waived or expenses reimbursed by First Trust for the Funds. As of July 31, 2019, 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, 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 fiscal year ended July 31, 2019, the cost of purchases and proceeds from sales of investments for each Fund, excluding short-term investments and in-kind transactions, were as follows:

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 according to the fee schedule set forth below: Number of Securities Creation in a Creation Unit Transaction Fee ------------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 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 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 according to the fee schedule set forth below: Number of Securities Redemption in a Creation Unit Transaction Fee ------------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 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. 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. Page 64 -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM -------------------------------------------------------------------------------- TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND: OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS We have audited the accompanying statements of assets and liabilities of First Trust Consumer Discretionary AlphaDEX(R) Fund, First Trust Consumer Staples AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund, First Trust Financials AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R) Fund, First Trust Industrials/Producer Durables AlphaDEX(R) Fund, First Trust Materials AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund, and First Trust Utilities AlphaDEX(R) Fund (the "Funds"), each a series of the First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust"), including the portfolios of investments, as of July 31, 2019, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of each of the nine portfolios included within the First Trust Exchange-Traded AlphaDEX(R) Fund as of July 31, 2019, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America. BASIS FOR OPINION These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on the Funds' financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of July 31, 2019, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. /s/ Deloitte & Touche LLP Chicago, Illinois September 24, 2019 We have served as the auditor of one or more First Trust investment companies since 2001.

Page 66 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 (UNAUDITED) RISK CONSIDERATIONS RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE, RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND. CONCENTRATION RISK. To the extent that a fund is able to invest a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund's investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund's corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is not concentrated. CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer's ability to make such payments. CYBER SECURITY RISK. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund's third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches. DERIVATIVES RISK. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivative. These risks are heightened when a fund's portfolio managers use derivatives to enhance the fund's return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund. EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the value of the fund's shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. ETF RISK. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF's shares, or decisions by an ETF's authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF's shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads. FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund's fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund's fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities. Page 67 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 (UNAUDITED) INDEX CONSTITUENT RISK. Certain funds may be a constituent of one or more indices. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could significantly increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund's net asset value could be negatively impacted and the fund's market price may be significantly below its net asset value during certain periods. INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund's costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders. INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund's investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests. 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. NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries. PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets. NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE REMUNERATION First Trust Advisors L.P. ("First Trust") is authorised and regulated by the U.S. Securities and Exchange Commission and is entitled to market shares of the First Trust Exchange-Traded AlphaDEX(R) Fund funds it manages (the "Funds") in certain member states in the European Economic Area in accordance with the cooperation arrangements in Article 42 of the Alternative Investment Fund Managers Directive (the "Directive"). First Trust is required under the Directive to make disclosures in respect of remuneration. The following disclosures are made in line with First Trust's interpretation of currently available regulatory guidance on remuneration disclosures. During the year ended December 31, 2018, the amount of remuneration paid (or to be paid) by First Trust Advisors L.P. in respect of the Funds is $3,416,811. This figure is comprised of $149,724 paid (or to be paid) in fixed compensation and $3,267,087 paid (or to be paid) in variable compensation. There were a total of 14 beneficiaries of the remuneration described above. Those amounts include $2,169,857 paid (or to be paid) to senior management of First Trust Advisors L.P. and $1,246,954 paid (or to be paid) to other employees whose professional activities have a material impact on the risk profiles of First Trust Advisors L.P. or the Funds (collectively, "Code Staff"). Page 68 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 (UNAUDITED) Code Staff included in the aggregated figures disclosed above are rewarded in line with First Trust's remuneration policy (the "Remuneration Policy") which is determined and implemented by First Trust's senior management. The Remuneration Policy reflects First Trust's ethos of good governance and encapsulates the following principal objectives: i. to provide a clear link between remuneration and performance of First Trust and to avoid rewarding for failure; ii. to promote sound and effective risk management consistent with the risk profiles of the Funds managed by First Trust; and iii. to remunerate staff in line with the business strategy, objectives, values and interests of First Trust and the Funds managed by First Trust in a manner that avoids conflicts of interest. First Trust assesses various risk factors which it is exposed to when considering and implementing remuneration for Code Staff and considers whether any potential award to such person(s) would give rise to a conflict of interest. First Trust does not reward failure, or consider the taking of risk or failure to take risk in its remuneration of Code Staff. First Trust assesses performance for the purposes of determining payments in respect of performance-related remuneration of Code Staff by reference to a broad range of measures including (i) individual performance (using financial and non-financial criteria), and (ii) the overall performance of First Trust. Remuneration is not based upon the performance of the Funds. The elements of remuneration are balanced between fixed and variable and the senior management sets fixed salaries at a level sufficient to ensure that variable remuneration incentivises and rewards strong individual performance but does not encourage excessive risk taking. No individual is involved in setting his or her own remuneration. ADVISORY AGREEMENT BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT The Board of Trustees (the "Board") of First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust"), including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement (the "Agreement") with First Trust Advisors L.P. (the "Advisor") on behalf of the following nine series of the Trust (each a "Fund" and collectively, the "Funds"): First Trust Consumer Discretionary AlphaDEX(R) Fund (FXD) First Trust Consumer Staples AlphaDEX(R) Fund (FXG) First Trust Energy AlphaDEX(R) Fund (FXN) First Trust Financials AlphaDEX(R) Fund (FXO) First Trust Health Care AlphaDEX(R) Fund (FXH) First Trust Industrials/Producer Durables AlphaDEX(R) Fund (FXR) First Trust Materials AlphaDEX(R) Fund (FXZ) First Trust Technology AlphaDEX(R) Fund (FXL) First Trust Utilities AlphaDEX(R) Fund (FXU) The Board approved the continuation of the Agreement for each Fund for a one-year period ending June 30, 2020 at a meeting held on June 2, 2019. The Board determined for each Fund that the continuation of the Agreement is in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its reasonable business judgment. To reach this determination for each Fund, the Board considered its duties under the Investment Company Act of 1940, as amended (the "1940 Act"), as well as under the general principles of state law, in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; the fiduciary duty of investment advisors with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards have fulfilled their duties; and the factors to be considered by the Board in voting on such agreements. At meetings held on April 18, 2019 and June 2, 2019, the Board, including the Independent Trustees, reviewed materials provided by the Advisor responding to requests for information from counsel to the Independent Trustees, submitted on behalf of the Independent Trustees, that, among other things, outlined: the services provided by the Advisor to each Fund (including the relevant personnel responsible for these services and their experience); the advisory fee rate payable by each Fund as compared to fees charged to a peer group of funds (the "Expense Group") and a broad peer universe of funds (the "Expense Universe"), each assembled by Broadridge Financial Solutions, Inc. ("Broadridge"), an independent source, and as compared to fees charged to other clients of the Advisor, including other exchange-traded funds ("ETFs") managed by the Advisor; the expense ratio of each Fund as compared to expense ratios Page 69 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 (UNAUDITED) of the funds in the Fund's Expense Group and Expense Universe; performance information for each Fund, including comparisons of each Fund's performance to that of one or more relevant benchmark indexes and to that of a performance group of funds and a broad performance universe of funds (the "Performance Universe"), each assembled by Broadridge; the nature of expenses incurred in providing services to each Fund and the potential for economies of scale, if any; financial data on the Advisor; any fall-out benefits to the Advisor and its affiliate, First Trust Portfolios L.P. ("FTP"); and information on the Advisor's compliance program. The Board reviewed initial materials with the Advisor at the meeting held on April 18, 2019, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor. Following the April meeting, independent legal counsel on behalf of the Independent Trustees requested certain clarifications and supplements to the materials provided, and the information provided in response to those requests was considered at an executive session of the Independent Trustees and independent legal counsel held prior to the June 2, 2019 meeting, as well as at the meeting held that day. The Board applied its business judgment to determine whether the arrangement between the Trust and the Advisor continues to be a reasonable business arrangement from each Fund's perspective. The Board determined that, given the totality of the information provided with respect to the Agreement, the Board had received sufficient information to renew the Agreement. The Board considered that shareholders chose to invest or remain invested in a Fund knowing that the Advisor manages the Fund and knowing the Fund's advisory fee. In reviewing the Agreement for each Fund, the Board considered the nature, extent and quality of the services provided by the Advisor under the Agreement. The Board considered that the Advisor is responsible for the overall management and administration of the Trust and each Fund and reviewed all of the services provided by the Advisor to the Funds, as well as the background and experience of the persons responsible for such services. In reviewing the services provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor's and each Fund's compliance with the 1940 Act, as well as each Fund's compliance with its investment objective, policies and restrictions. The Board also considered a report from the Advisor with respect to its risk management functions related to the operation of the Funds. Finally, as part of the Board's consideration of the Advisor's services, the Advisor, in its written materials and at the April 18, 2019 meeting, described to the Board the scope of its ongoing investment in additional infrastructure and personnel to maintain and improve the quality of services provided to the Funds and the other funds in the First Trust Fund Complex. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of the services provided to the Trust and each Fund by the Advisor under the Agreement have been and are expected to remain satisfactory and that the Advisor has managed each Fund consistent with its investment objective, policies and restrictions. The Board considered the advisory fee rate payable by each Fund under the Agreement for the services provided. The Board considered that the Advisor agreed to extend the current expense cap for each Fund through November 30, 2020. For each Fund, the Board noted that expenses borne or fees waived by the Advisor are to be subject to reimbursement by the Fund for up to three years from the date the expense was incurred or fee was waived, but no reimbursement payment would be made by the Fund if it would result in the Fund exceeding an expense ratio equal to the expense cap in place at the time the expenses were borne or fees were waived by the Advisor. The Board received and reviewed information showing the advisory or unitary fee rates and expense ratios of the peer funds in the Expense Groups, as well as advisory and unitary fee rates charged by the Advisor to other fund (including ETFs) and non-fund clients, as applicable. Because each Fund's Expense Group included peer funds that pay a unitary fee, the Board determined that expense ratios were the most relevant comparative data point. Based on the information provided, the Board noted that the total (net) expense ratio of each Fund was above the median total (net) expense ratio of the peer funds in its respective Expense Group. With respect to the Expense Groups, the Board, at the April 18, 2019 meeting, discussed with Broadridge its methodology for assembling peer groups and discussed with the Advisor limitations in creating peer groups for index ETFs, including differences in underlying indexes and index-tracking methodologies that can result in greater management complexities across seemingly comparable ETFs, and different business models that may affect the pricing of services among ETF sponsors. The Board took these limitations and differences into account in considering the peer data. With respect to fees charged to other non-ETF clients, the Board considered differences between the Funds and other non-ETF clients that limited their comparability. In considering the advisory fee rates overall, the Board also considered the Advisor's statement that it seeks to meet investor needs through innovative and value-added investment solutions and the Advisor's description of its long-term commitment to each Fund. The Board considered performance information for each Fund. The Board noted the process it has established for monitoring each Fund's performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor for the Funds. The Board determined that this process continues to be effective for reviewing each Fund's performance. The Board received and reviewed information for periods ended December 31, 2018 regarding the performance of each Fund's underlying index, the correlation between each Fund's performance and that of its underlying index, each Fund's tracking difference and each Fund's excess return as compared to its benchmark index. The Board considered the Advisor's explanations of how the AlphaDEX(R) stock selection methodology impacts Fund performance in various market environments, and the Advisor's statement that AlphaDEX(R) is designed to provide long-term outperformance. Based on the information provided and its ongoing review of performance, the Board concluded that each Fund was correlated to its underlying index and that the tracking difference for each Fund was within a reasonable Page 70 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2019 (UNAUDITED) range. In addition, the Board reviewed data prepared by Broadridge comparing each Fund's performance to that of its respective Performance Universe and to that of a broad-based benchmark index, but given each Fund's objective of seeking investment results that correspond generally to the performance of its underlying index, the Board placed more emphasis on its review of correlation and tracking difference. On the basis of all the information provided on the fees, expenses and performance of each Fund and the ongoing oversight by the Board, the Board concluded that the advisory fee for each Fund continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor to each Fund under the Agreement. The Board considered information and discussed with the Advisor whether there were any economies of scale in connection with providing advisory services to the Funds and noted the Advisor's statement that it believes its expenses will likely increase over the next twelve months as the Advisor continues to hire personnel and build infrastructure, including technology, to improve the services to the Funds. The Board considered the revenues and allocated costs (including the allocation methodology) of the Advisor in serving as investment advisor to each Fund for the twelve months ended December 31, 2018 and the estimated profitability level for each Fund calculated by the Advisor based on such data, as well as complex-wide and product-line profitability data for the same period. The Board noted the inherent limitations in the profitability analysis and concluded that, based on the information provided, the Advisor's profitability level for each Fund was not unreasonable. In addition, the Board considered fall-out benefits described by the Advisor that may be realized from its relationship with the Funds. The Board considered that the Advisor had identified as a fall-out benefit to the Advisor and FTP their exposure to investors and brokers who, absent their exposure to the Funds, may have had no dealings with the Advisor or FTP, and noted that the Advisor does not utilize soft dollars in connection with the Funds. The Board concluded that the character and amount of potential fall-out benefits to the Advisor were not unreasonable. Based on all of the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreement continue to be fair and reasonable and that the continuation of the Agreement is in the best interests of each Fund. No single factor was determinative in the Board's analysis.

Forward-looking statements include statements regarding the goals, beliefs, plans or current expectations of First Trust Advisors L.P. ("First Trust" or the "Advisor") and its representatives, taking into account the information currently available to them. Forward-looking statements include all statements that do not relate solely to current or historical fact. For example, forward-looking statements include the use of words such as "anticipate," "estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or other words that convey uncertainty of future events or outcomes. Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of any series of First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust") described in this report (each such series is referred to as a "Fund" and collectively, as the "Funds") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and its representatives only as of the date hereof. We undertake no obligation to publicly revise or update these forward-looking statements to reflect events and circumstances that arise after the date hereof. PERFORMANCE AND RISK DISCLOSURE There is no assurance that any Fund described in this report will achieve its investment objective. Each Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund 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.

Page 1 -------------------------------------------------------------------------------- SHAREHOLDER LETTER -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND ANNUAL LETTER FROM THE CHAIRMAN AND CEO JULY 31, 2019 Dear Shareholders: One thing we can all agree on and expect: headline news coming out of Washington, DC continues to influence the financial markets. By late February of 2019, President Trump announced the U.S. was close to a trade deal with China, yet by May 10, existing tariffs on Chinese imports jumped from 10% to 25%. Furthermore, the President's threat of additional tariffs on the remaining $300 billion in Chinese imports became a reality with his announcement after a Federal Funds rate cut of 0.25% on the last day of July. This led many to wonder if these events could be signaling a recession. While reticent investors sought cover in "risk-on" assets, calendar year-to-date performances of broad markets as of July 31, 2019, were strong. Both U.S. and world equities, as indicated by the S&P 500(R) Index and the MSCI All Country World Index, returned 20.24% and 16.57%, respectively. Bonds, as measured by the Bloomberg Barclays U.S. Aggregate Bond Index, returned 6.35%, for the same period. Despite the ongoing bluster of the news cycle, we believe the economy is doing well and productivity growth, due to deregulation and lower taxes on corporate profits, has improved over the last two years. o The Consumer Confidence Index of 135.7 for July is strong and at the highest level this year. o The U.S. inflation rate hovers near 2%, on average, as it has for the last decade. o July's unemployment rate of 3.7% barely moved from 3.6% in May, which was the lowest level since December of 1969. Before you head for the exits or reach for the antacids due to the latest political equivocation, keep a balanced perspective in view. Remember, no one can predict the inevitable and expected market fluctuations. Speak periodically with your investment professional, who can provide insight when it comes to investing and discovering opportunities when they arise. Thank you for giving First Trust the opportunity to be a part of your financial plan. We value our relationship with you. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 2 -------------------------------------------------------------------------------- MARKET OVERVIEW -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND ANNUAL REPORT JULY 31, 2019 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 25 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 trade conflict between the U.S. and China was nearly 17-months-old at the close of July 2019. In our opinion, the most notable change from the business climate of 2018 to that of 2019 was the Trump Administration's ratcheting up of tariffs on roughly $200 billion of imported goods from China. On May 10, 2019, tariffs jumped from 10% to 25%. At the end of July, President Trump decided to up the ante on China by announcing a 10% tariff on the remaining $300 billion or so in goods shipped to the U.S. annually. The Trump Administration tends to play the tariff card whenever trade negotiations get bogged down. The tariff was to begin on September 1, 2019. We learned in August, however, that President Trump softened his stance by shielding some consumer products from the new tariff until at least December in order to allow retailers to stock their inventories for the critical holiday shopping season. The ongoing dispute has become a drag on global growth, according to such organizations as the International Monetary Fund. While the U.S. economy continues to flourish relative to many other developed and emerging economies, recent data suggests that China's economy is being stressed by the tariffs. China's gross domestic product rose at an annualized pace of 6.2% in the second quarter of 2019, the slowest rate of growth in 27 years, according to MarketWatch. CNBC reported that, as of July 1, 2019, the current U.S. economic expansion will become the longest in its history, breaking the previous record of 120 months of growth from March 1991 to March 2001, according to data from the National Bureau of Economic Research. The recent escalation in the trade conflict between the U.S. and China has investors flocking to safe-haven assets around the globe, including bonds. One reflection of this is the market value of the Bloomberg Barclays Global Negative Yielding Debt Index, which closed the July 31, 2019 trading session at $14.01 trillion, according to Bloomberg. Another is the plunge in the yield on the benchmark 10-year Treasury Note, which declined by 94 basis points to 2.02% over the past 12 months. More than half of that drop transpired after mid-April 2019. ETFGI, an industry 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 $5.74 trillion in July 2019, up from $5.12 trillion a year ago, according to its own release. Total assets of U.S. listed ETFs/ETPs also stood at an all-time high of $4.02 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 July 31, 2019, U.S. Equity funds/ETFs reported estimated net inflows totaling $40.68 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 $242.78 billion, compared to estimated net outflows totaling $202.10 billion for actively managed U.S. Equity funds/ETFs for the same period. For the 12-month period ended July 31, 2019, U.S. Large Blend, U.S. Large Growth and U.S. Large Value equity funds/ETFs reported estimated net flows totaling $175.56 billion, -$46.08 billion and -$19.60 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 $11.22 billion, -$8.41 billion and -$14.71 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 $2.75 billion, -$6.11 billion and -$2.45 billion, respectively, for the same period. Investors were clearly more comfortable funneling their capital into blended portfolios. For the 12-month period ended July 31, 2019, the S&P 500(R) Index posted a total return of 7.99%, according to Bloomberg. Growth stocks outperformed value stocks in the same period. The S&P 500(R) Growth Index posted a total return of 9.55%, compared to 6.28% for the S&P 500(R) Value Index for the period. The S&P MidCap 400(R) Index posted a total return of 0.79% in the same period. Growth stocks outperformed value stocks in the period. The S&P MidCap 400(R) Growth Index posted a total return of 1.81%, compared to -0.24% for the S&P MidCap 400(R) Value Index for the same period. The S&P SmallCap 600(R) Index posted a total return of -6.75% in the period. Growth stocks outperformed value stocks in the period. The S&P SmallCap 600(R) Growth Index posted a total return of -4.81%, compared to -8.48% for the S&P SmallCap 600(R) Value Index for the same period. Page 3 -------------------------------------------------------------------------------- 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.

(1) Performance data is not available for all the periods shown in the table for the index because performance data does not exist for some of the entire periods. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FEX's one-year net asset value ("NAV") return of 3.48% underperformed the S&P 500(R) Index ("Benchmark") return of 7.99% by 4.51%. The Information Technology sector received the largest allocation and contributed the most to the Fund's return during the period. This sector carried an average weight of 16.6%, returned 11.5%, and contributed 1.5% to the Fund's return. The Energy sector, meanwhile, was the greatest drag on the Fund's return with a 6.1% allocation, -21.7% performance and -1.9% contribution to the Fund's return. On a relative basis, the Fund underperformed the Benchmark. The Benchmark over-weighted Information Technology, in comparison to the Fund, and this well-performing sector caused -1.4% underperformance for the Fund versus the Benchmark. Some outperformance for the Fund came from investments in Industrials, which earned 0.4% outperformance versus the Benchmark. ----------------------------- Nasdaq(R) and the Index are trademarks and service marks of Nasdaq, Inc.

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.

On a relative basis, the Fund outperformed the Benchmark. The greatest contribution to the outperformance came from investments in the Consumer Discretionary sector. The Consumer Discretionary investments in the Fund outperformed those in the Benchmark, resulting in 1.4% outperformance for the Fund. The poorly returning Energy sector, meanwhile, caused -1.9% underperformance for the Fund, as the Fund allocated more weight to Energy than did the Benchmark. ----------------------------- Nasdaq(R) and the Index are trademarks and service marks of Nasdaq, Inc.

The Health Care sector received the largest allocation in the Fund over the period. This sector carried a 24.7% average weight in the Fund, returned -9.2% and contributed -2.8% to the Fund's total return. The greatest contribution to the Fund's return were the investments in the Information Technology sector. This sector received a 16.8% return which came from the investments in the Energy sector, which received a 4.2% allocation, returned -59.6% and contributed -4.8% to the Fund's total return. On a relative basis, the Fund outperformed the Benchmark. The Fund over-allocated and underperformed in the Energy sector, leading to a -3.1% Fund underperformance versus the Benchmark. Meanwhile, the investments in the Information Technology sector, which performed much better than those in the Benchmark, resulted in 3.4% outperformance for the Fund versus the Benchmark. ----------------------------- Nasdaq(R) and the Index are trademarks and service marks of Nasdaq, Inc.

(1) Performance data is not available for all the periods shown in the table for the index because performance data does not exist for some of the entire periods. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FMK's one-year NAV return of 3.24% underperformed the S&P 100(R) Index ("Benchmark") return of 8.34% by 5.10%. The Information Technology sector was the Fund's heaviest allocated sector over the period with a 19.4% allocation. However, it was the Communication Services sector that contributed the most to the Fund over the period with a 3.2% contribution, stemming from its 16.3% allocation and 20.2% return. The Fund had a relatively smaller allocation to the Utilities sector with a 3% weighting. This sector was the top performing sector in the Fund with a 25.8% return. The least performing sector in the Fund was the Energy sector with a -15.0% return and -1.3% contribution, stemming from its 9.7% allocation. The Fund's least contributing sector was the Consumer Staples sector with a -1.5% contribution, stemming from its -14.7% return and 9.8% allocation. On a relative basis, the Fund underperformed the Benchmark. The primary cause of the underperformance is attributable to the Fund underperforming the Benchmark among Information Technology securities by -10.2%, which created -3.7% of relative drag. The Fund outperformed the Benchmark among Communication Services securities by 11.6%, which created 1.2% of relative outperformance. ----------------------------- Nasdaq(R) and the Index are trademarks and service marks of Nasdaq, Inc.

"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. Page 28 FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS UNDERSTANDING YOUR FUND EXPENSES JULY 31, 2019 (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 July 31, 2019. 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.

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 ("FASB") Accounting Standards Codification ("ASC") Topic 946, "Financial Services-Investment Companies." The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. A. PORTFOLIO VALUATION Each Fund's NAV is determined daily as of the close of regular trading on the New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Each Fund's NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding. Page 121 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 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. Page 122 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates). o Inputs that are derived principally from or corroborated by observable market data by correlation or other means. o Level 3 - Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity's own assumptions about the assumptions that market participants would use in pricing the investment. The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund's investments as of July 31, 2019, 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 Page 123 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 the same manner as other dividend and interest income. At July 31, 2019, all the Funds except FEX, FTA, and FMK had securities in the securities lending program. During the fiscal year ended July 31, 2019, all the Funds except FMK participated in the securities lending program. In the event of a default by a borrower with respect to any loan, BBH will exercise any and all remedies provided under the applicable borrower agreement to make the Funds whole. These remedies include purchasing replacement securities by applying the collateral held from the defaulting broker against the purchase cost of the replacement securities. If, despite such efforts by BBH to exercise these remedies, a Fund sustains losses as a result of a borrower's default, BBH will indemnify the Fund by purchasing replacement securities at its own expense, or paying the Fund an amount equal to the market value of the replacement securities, subject to certain limitations which are set forth in detail in the Securities Lending Agency Agreement between the Trust on behalf of the Funds and BBH. E. REPURCHASE AGREEMENTS Repurchase agreements involve the purchase of securities subject to the seller's agreement to repurchase the securities at a mutually agreed upon date and price, under the terms of a Master Repurchase Agreement ("MRA"). During the term of a repurchase agreement, the value of the underlying securities held as collateral on behalf of a Fund, including accrued interest, is required to exceed the value of the repurchase agreement, including accrued interest. The underlying securities for all repurchase agreements are held at the Funds' custodian or designated sub-custodians under tri-party repurchase agreements. MRAs govern transactions between a Fund and select counterparties. The MRAs contain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for repurchase agreements. Repurchase agreements received for lending securities are collateralized by U.S. Treasury securities. The U.S. Treasury securities are held in a joint custody account at BBH on behalf of the Funds participating in the securities lending program. In the event the counterparty defaults on the repurchase agreement, the U.S. Treasury securities can either be maintained as part of a Fund's portfolio or sold for cash. A Fund could suffer a loss to the extent that the proceeds from the sale of the underlying collateral held by the Fund are less than the repurchase price and the Fund's costs associated with the delay and enforcement of the MRA. While the Funds may invest in repurchase agreements, any repurchase agreements held by the Funds during the fiscal year ended July 31, 2019, 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:

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 July 31, 2019, 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.

Certain losses realized during the current fiscal year may be deferred and treated as occurring the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended July 31, 2019, the Funds had no net late year ordinary or capital losses. In order to present paid-in capital and accumulated distributable earnings (loss) (which consists of accumulated net investment income (loss), accumulated net realized gain (loss) on investments and net unrealized appreciation (depreciation) on investments) on the Statements of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to paid-in capital, accumulated net investment income (loss) and accumulated net realized gain (loss) on investments. These adjustments are primarily due to the difference between book and tax treatments of income and gains on various investment securities held by the Funds and in-kind transactions. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended July 31, 2019, the adjustments for each Fund were as follows: Page 126 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019

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. I. NEW ACCOUNTING PRONOUNCEMENT On August 28, 2018, the FASB issued Accounting Standards Update ("ASU") 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," which amends the fair value measurement disclosure requirements of ASC 820. The amendments of ASU 2018-13 include new, eliminated, and modified disclosure requirements of ASC 820. In addition, the amendments clarify that materiality is an appropriate consideration of entities when evaluating disclosure requirements. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Funds have early adopted ASU 2018-13 for these financial statements, which did not result in a material impact. 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. Page 127 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 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 its Expense Cap. These amounts would be included in "Expenses previously waived or reimbursed" on the Statements of Operations. The advisory fee waivers and expense reimbursements for the fiscal year ended July 31, 2019 and fees waived or expenses borne by First Trust subject to recovery from the applicable Fund for the periods indicated were as follows:

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, 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.

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 according to the fee schedule set forth below: Number of Securities Creation in a Creation Unit Transaction Fee -------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 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 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 according to the fee schedule set forth below: Number of Securities Redemption in a Creation Unit Transaction Fee -------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 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. 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. Page 129 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 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. Page 130 -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM -------------------------------------------------------------------------------- TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND: OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS We have audited the accompanying statements of assets and liabilities of First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First Trust Multi Cap Value AlphaDEX(R) Fund, First Trust Multi Cap Growth AlphaDEX(R) Fund, First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid Cap Growth AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First Trust Small Cap Growth AlphaDEX(R) Fund, and First Trust Mega Cap AlphaDEX(R) Fund (the "Funds"), each a series of the First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust"), including the portfolios of investments, as of July 31, 2019, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of each of the twelve portfolios included within the First Trust Exchange-Traded AlphaDEX(R) Fund as of July 31, 2019, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America. BASIS FOR OPINION These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on the Funds' financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of July 31, 2019, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion. /s/ Deloitte & Touche LLP Chicago, Illinois September 24, 2019 We have served as the auditor of one or more First Trust investment companies since 2001.

Page 132 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 (UNAUDITED) RISK CONSIDERATIONS RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE, RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND. CONCENTRATION RISK. To the extent that a fund is able to invest a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund's investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund's corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is not concentrated. CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer's ability to make such payments. CYBER SECURITY RISK. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund's third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches. DERIVATIVES RISK. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivative. These risks are heightened when a fund's portfolio managers use derivatives to enhance the fund's return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund. EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the value of the fund's shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market. ETF RISK. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF's shares, or decisions by an ETF's authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF's shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads. FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund's fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund's fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or "junk" bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities. Page 133 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 (UNAUDITED) INDEX CONSTITUENT RISK. Certain funds may be a constituent of one or more indices. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could significantly increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund's net asset value could be negatively impacted and the fund's market price may be significantly below its net asset value during certain periods. INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund's costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders. INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund's investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests. 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. NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries. PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets. NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE REMUNERATION First Trust Advisors L.P. ("First Trust") is authorised and regulated by the U.S. Securities and Exchange Commission and is entitled to market shares of the First Trust Exchange-Traded AlphaDEX(R) Fund funds it manages (the "Funds") in certain member states in the European Economic Area in accordance with the cooperation arrangements in Article 42 of the Alternative Investment Fund Managers Directive (the "Directive"). First Trust is required under the Directive to make disclosures in respect of remuneration. The following disclosures are made in line with First Trust's interpretation of currently available regulatory guidance on remuneration disclosures. During the year ended December 31, 2018, the amount of remuneration paid (or to be paid) by First Trust Advisors L.P. in respect of the Funds is $2,633,004. This figure is comprised of $115,378 paid (or to be paid) in fixed compensation and $2,517,626 paid (or to be paid) in variable compensation. There were a total of 14 beneficiaries of the remuneration described above. Those amounts include $1,672,097 paid (or to be paid) to senior management of First Trust Advisors L.P. and $960,907 paid (or to be paid) to other employees whose professional activities have a material impact on the risk profiles of First Trust Advisors L.P. or the Funds (collectively, "Code Staff"). Page 134 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 (UNAUDITED) Code Staff included in the aggregated figures disclosed above are rewarded in line with First Trust's remuneration policy (the "Remuneration Policy") which is determined and implemented by First Trust's senior management. The Remuneration Policy reflects First Trust's ethos of good governance and encapsulates the following principal objectives: i. to provide a clear link between remuneration and performance of First Trust and to avoid rewarding for failure; ii. to promote sound and effective risk management consistent with the risk profiles of the Funds managed by First Trust; and iii. to remunerate staff in line with the business strategy, objectives, values and interests of First Trust and the Funds managed by First Trust in a manner that avoids conflicts of interest. First Trust assesses various risk factors which it is exposed to when considering and implementing remuneration for Code Staff and considers whether any potential award to such person(s) would give rise to a conflict of interest. First Trust does not reward failure, or consider the taking of risk or failure to take risk in its remuneration of Code Staff. First Trust assesses performance for the purposes of determining payments in respect of performance-related remuneration of Code Staff by reference to a broad range of measures including (i) individual performance (using financial and non-financial criteria), and (ii) the overall performance of First Trust. Remuneration is not based upon the performance of the Funds. The elements of remuneration are balanced between fixed and variable and the senior management sets fixed salaries at a level sufficient to ensure that variable remuneration incentivises and rewards strong individual performance but does not encourage excessive risk taking. No individual is involved in setting his or her own remuneration. ADVISORY AGREEMENT BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT The Board of Trustees (the "Board") of First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust"), including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreements (as applicable to a specific Fund, the "Agreement" and collectively, the "Agreements") with First Trust Advisors L.P. (the "Advisor") on behalf of the following twelve series of the Trust (each a "Fund" and collectively, the "Funds"): First Trust Large Cap Core AlphaDEX(R) Fund (FEX) First Trust Mid Cap Core AlphaDEX(R) Fund (FNX) First Trust Small Cap Core AlphaDEX(R) Fund (FYX) First Trust Multi Cap Growth AlphaDEX(R) Fund (FAD) First Trust Multi Cap Value AlphaDEX(R) Fund (FAB) First Trust Large Cap Growth AlphaDEX(R) Fund (FTC) First Trust Large Cap Value AlphaDEX(R) Fund (FTA) First Trust Mid Cap Growth AlphaDEX(R) Fund (FNY) First Trust Mid Cap Value AlphaDEX(R) Fund (FNK) First Trust Small Cap Growth AlphaDEX(R) Fund (FYC) First Trust Small Cap Value AlphaDEX(R) Fund (FYT) First Trust Mega Cap AlphaDEX(R) Fund (FMK) The Board approved the continuation of the Agreement for each Fund for a one-year period ending June 30, 2020 at a meeting held on June 2, 2019. The Board determined for each Fund that the continuation of the Agreement is in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its reasonable business judgment. To reach this determination for each Fund, the Board considered its duties under the Investment Company Act of 1940, as amended (the "1940 Act"), as well as under the general principles of state law, in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; the fiduciary duty of investment advisors with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards have fulfilled their duties; and the factors to be considered by the Board in voting on such agreements. At meetings held on April 18, 2019 and June 2, 2019, the Board, including the Independent Trustees, reviewed materials provided by the Advisor responding to requests for information from counsel to the Independent Trustees, submitted on behalf of the Independent Trustees, that, among other things, outlined: the services provided by the Advisor to each Fund (including the relevant personnel responsible for these services and their experience); the Page 135 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 (UNAUDITED) advisory or unitary fee rate payable by each Fund as compared to fees charged to a peer group of funds (the "Expense Group") and a broad peer universe of funds (the "Expense Universe"), each assembled by Broadridge Financial Solutions, Inc. ("Broadridge"), an independent source, and as compared to fees charged to other clients of the Advisor, including other exchange-traded funds ("ETFs") managed by the Advisor; the expense ratio of each Fund as compared to expense ratios of the funds in the Fund's Expense Group and Expense Universe; performance information for each Fund, including comparisons of each Fund's performance to that of one or more relevant benchmark indexes and to that of a performance group of funds and a broad performance universe of funds (the "Performance Universe"), each assembled by Broadridge; the nature of expenses incurred in providing services to each Fund and the potential for economies of scale, if any; financial data on the Advisor; any fall-out benefits to the Advisor and its affiliate, First Trust Portfolios L.P. ("FTP"); and information on the Advisor's compliance program. The Board reviewed initial materials with the Advisor at the meeting held on April 18, 2019, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor. Following the April meeting, independent legal counsel on behalf of the Independent Trustees requested certain clarifications and supplements to the materials provided, and the information provided in response to those requests was considered at an executive session of the Independent Trustees and independent legal counsel held prior to the June 2, 2019 meeting, as well as at the meeting held that day. The Board applied its business judgment to determine whether the arrangement between the Trust and the Advisor continues to be a reasonable business arrangement from each Fund's perspective. The Board determined that, given the totality of the information provided with respect to the Agreements, the Board had received sufficient information to renew the Agreements. The Board considered that shareholders chose to invest or remain invested in a Fund knowing that the Advisor manages the Fund and knowing the Fund's advisory or unitary fee. In reviewing the Agreement for each Fund, the Board considered the nature, extent and quality of the services provided by the Advisor under the Agreement. The Board considered that the Advisor is responsible for the overall management and administration of the Trust and each Fund and reviewed all of the services provided by the Advisor to the Funds, as well as the background and experience of the persons responsible for such services. In reviewing the services provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor's and each Fund's compliance with the 1940 Act, as well as each Fund's compliance with its investment objective, policies and restrictions. The Board also considered a report from the Advisor with respect to its risk management functions related to the operation of the Funds. Finally, as part of the Board's consideration of the Advisor's services, the Advisor, in its written materials and at the April 18, 2019 meeting, described to the Board the scope of its ongoing investment in additional infrastructure and personnel to maintain and improve the quality of services provided to the Funds and the other funds in the First Trust Fund Complex. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of the services provided to the Trust and each Fund by the Advisor under the Agreements have been and are expected to remain satisfactory and that the Advisor has managed each Fund consistent with its investment objective, policies and restrictions. For FEX, FNX, FYX, FAD, FAB, FTC and FTA (the "Non-Unitary Fee Funds"), the Board considered the advisory fee rate payable by each Non-Unitary Fee Fund under the applicable Agreement for the services provided. The Board considered that the Advisor agreed to extend the current expense cap for each Non-Unitary Fee Fund through November 30, 2020. For each Non-Unitary Fee Fund, the Board noted that expenses borne or fees waived by the Advisor are to be subject to reimbursement by the Non-Unitary Fee Fund for up to three years from the date the expense was incurred or fee was waived, but no reimbursement payment would be made by the Non-Unitary Fee Fund if it would result in the Non-Unitary Fee Fund exceeding an expense ratio equal to the expense cap in place at the time the expenses were borne or fees were waived by the Advisor. For FNY, FNK, FYC, FYT and FMK (the "Unitary Fee Funds"), the Board considered the unitary fee rate payable by each Unitary Fee Fund under the applicable Agreement for the services provided. The Board considered that as part of the unitary fee the Advisor is responsible for each Unitary Fee Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services and license fees, if any, but excluding the fee payment under the applicable Agreement and interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. The Board received and reviewed information showing the advisory or unitary fee rates and expense ratios of the peer funds in the Expense Groups, as well as advisory and unitary fee rates charged by the Advisor to other fund (including ETFs) and non-fund clients, as applicable. Because each Fund's Expense Group included peer funds that pay a unitary fee and because each Unitary Fee Fund pays a unitary fee, the Board determined that expense ratios were the most relevant comparative data point. Based on the information provided, the Board noted that the total (net) expense ratio of FTC was below the median total (net) expense ratio of the peer funds in its Expense Group and that the total (net) expense ratio of each other Non-Unitary Fee Fund and the unitary fee for each Unitary Fee Fund were above the median total (net) expense ratio of the peer funds in each Fund's respective Expense Group. With respect to the Expense Groups, the Board, at the April 18, 2019 meeting, discussed with Broadridge its methodology for assembling peer groups and discussed with the Advisor limitations in creating peer groups for index ETFs, including differences in underlying indexes and index-tracking methodologies that can result in greater management complexities across seemingly comparable ETFs, and different business Page 136 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2019 (UNAUDITED) models that may affect the pricing of services among ETF sponsors. The Board took these limitations and differences into account in considering the peer data. With respect to fees charged to other non-ETF clients, the Board considered differences between the Funds and other non-ETF clients that limited their comparability. In considering the advisory and unitary fee rates overall, the Board also considered the Advisor's statement that it seeks to meet investor needs through innovative and value-added investment solutions and the Advisor's description of its long-term commitment to each Fund. The Board considered performance information for each Fund. The Board noted the process it has established for monitoring each Fund's performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor for the Funds. The Board determined that this process continues to be effective for reviewing each Fund's performance. The Board received and reviewed information for periods ended December 31, 2018 regarding the performance of each Fund's underlying index, the correlation between each Fund's performance and that of its underlying index, each Fund's tracking difference and each Fund's excess return as compared to its benchmark index. The Board noted that, effective April 8, 2016, each Fund changed its underlying index to an index developed and maintained by Nasdaq, Inc. using the AlphaDEX(R) stock selection methodology and that the performance information included a blend of the old and new indexes. The Board considered the Advisor's explanations of how the AlphaDEX(R) stock selection methodology impacts Fund performance in various market environments, and the Advisor's statement that AlphaDEX(R) is designed to provide long-term outperformance. Based on the information provided and its ongoing review of performance, the Board concluded that each Fund was correlated to its underlying index and that the tracking difference for each Fund was within a reasonable range. In addition, the Board reviewed data prepared by Broadridge comparing each Fund's performance to that of its respective Performance Universe and to that of a broad-based benchmark index, but given each Fund's objective of seeking investment results that correspond generally to the performance of its underlying index, the Board placed more emphasis on its review of correlation and tracking difference. On the basis of all the information provided on the fees, expenses and performance of each Fund and the ongoing oversight by the Board, the Board concluded that the advisory or unitary fee for each Fund continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor to each Fund under the Agreements. The Board considered information and discussed with the Advisor whether there were any economies of scale in connection with providing advisory services to the Funds and noted the Advisor's statement that it believes its expenses will likely increase over the next twelve months as the Advisor continues to hire personnel and build infrastructure, including technology, to improve the services to the Funds. For the Unitary Fee Funds, the Board noted that any reduction in fixed costs associated with the management of the Unitary Fee Funds would benefit the Advisor, but that the unitary fee structure provides a level of certainty in expenses for the Unitary Fee Funds. The Board considered the revenues and allocated costs (including the allocation methodology) of the Advisor in serving as investment advisor to each Fund for the twelve months ended December 31, 2018 and the estimated profitability level for each Fund calculated by the Advisor based on such data, as well as complex-wide and product-line profitability data, for the same period. The Board noted the inherent limitations in the profitability analysis and concluded that, based on the information provided, the Advisor's profitability level for each Fund was not unreasonable. In addition, the Board considered fall-out benefits described by the Advisor that may be realized from its relationship with the Funds. The Board considered that the Advisor had identified as a fall-out benefit to the Advisor and FTP their exposure to investors and brokers who, absent their exposure to the Funds, may have had no dealings with the Advisor or FTP, and noted that the Advisor does not utilize soft dollars in connection with the Funds. The Board concluded that the character and amount of potential fall-out benefits to the Advisor were not unreasonable. Based on all of the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreements continue to be fair and reasonable and that the continuation of the Agreements is in the best interests of each Fund. No single factor was determinative in the Board's analysis.

The Committee is also responsible for the pre-approval of the independent auditor's engagements for non-audit services with the registrant's adviser (not including a sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser) and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the registrant, if the engagement relates directly to the operations and financial reporting of the registrant, subject to the de minimis exceptions for non-audit services described in Rule 2-01 of Regulation S-X. If the independent auditor has provided non-audit services to the registrant's adviser (other than any sub-adviser whose role is primarily portfolio management and is sub-contracted with or overseen by another investment adviser) and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to its policies, the Committee will consider whether the provision of such non-audit services is compatible with the auditor's independence. (e)(2) The percentage of services described in each of paragraphs (b) through (d) for the registrant and the registrant's investment adviser and distributor of this Item that were approved by the audit committee pursuant to the pre-approval exceptions included in paragraph (c)(7)(i)(C) or paragraph(C)(7)(ii) of Rule 2-01 of Regulation S-X are as follows: Registrant: Adviser and Distributor: ----------- ------------------------ (b) 0% (b) 0% (c) 0% (c) 0% (d) 0% (d) 0% (f) The percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees was less than fifty percent. (g) The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant for 2018 were $45,675 for the registrant, $43,390 for the registrant's investment adviser and $68,710 for the registrant's distributor, and for 2019 were $61,425 for the registrant, $33,300 for the registrant's investment adviser and $46,000 for the registrant's distributor. (h) The registrant's audit committee of its Board of Trustees has determined that the provision of non-audit services that were rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
