Caution Regarding Forward-Looking Statements

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

Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of First Trust Energy Infrastructure Fund (the "Fund") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and/or Sub-Advisor and their respective representatives 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.

Managed Distribution Policy

The Board of Trustees of the Fund has approved a managed distribution policy for the Fund (the "Plan") in reliance on exemptive relief received from the Securities and Exchange Commission that permits the Fund to make periodic distributions of long-term capital gains as frequently as monthly each tax year. Under the Plan, the Fund currently intends to continue to pay a recurring monthly distribution in the amount of $0.0625 per Common Share that reflects the distributable cash flow of the Fund. A portion of this monthly distribution may include realized capital gains. This may result in a reduction of the long-term capital gain distribution necessary at year end by distributing realized capital gains throughout the year. The annual distribution rate is independent of the Fund's performance during any particular period. Accordingly, you should not draw any conclusions about the Fund's investment performance from the amount of any distribution or from the terms of the Plan. The Board of Trustees may amend or terminate the Plan at any time without prior notice to shareholders.

Performance and Risk Disclosure

There is no assurance that the Fund will achieve its investment objective. The Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund's shares may therefore be less than what you paid for them. Accordingly, you can lose money by investing in the Fund. See "Principal Risks" in the Investment Objective, Policies, Risks and Effects of Leverage section of this report for a discussion of certain other risks of investing in the Fund.

First Trust Energy Infrastructure Fund (FIF)

Annual Letter from the Chairman and CEO

November 30, 2020

Dear Shareholders,

First Trust is pleased to provide you with the annual report for the First Trust Energy Infrastructure Fund (the "Fund"), which contains detailed information about the Fund for the twelve months ended November 30, 2020.

Is anybody else ready for 2020 to be over? This year has really tested people in so many ways. As of the midpoint of December 2020, the U.S. had only recovered 56% of the 22 million jobs lost in the coronavirus ("COVID-19") pandemic recession, according to the U.S. Department of Labor. Feeding America, a hunger relief organization, recently reported that as many as 50 million people in the U.S. have experienced food insecurity in 2020, up from around 35 million last year, according to National Public Radio. As has been the case for as long as I can remember, the good citizens that make up our great country rise to the occasion when presented with a challenge. Often the response calls for some degree of ingenuity, but sometimes tapping into our generosity is enough. An estimated $2.47 billion was raised in the U.S. during the ninth annual Giving Tuesday on December 1, 2020, which represented a 25% increase from the $1.97 billion raised in 2019, according to Philanthropy News Digest. The number of people that participated in Giving Tuesday increased by 29% to 34.8 million. Now that is working the problem!

Are you the type of person who believes the glass is half-full or half-empty? I am in the half-full camp. When I look at the performance of the U.S. stock and bond markets, I'm seeing optimism about where Corporate America is headed. The S&P 500® Index posted a total return of 19.98% for the six-month period ended November 30, 2020, compared to 6.33% for the ICE BofA U.S. Corporate Index, according to Bloomberg. The returns are also positive on a year-to-date basis. From December 31, 2019 through November 30, 2020, the S&P 500® Index and ICE BofA U.S. Corporate Index returned 14.02% and 9.27%, respectively.

Do you follow politics? I do. Politics impact the markets over time, particularly when legislative change is involved. With the November 2020 election results certified, we now know that Joe Biden will be sworn in as our next president on January 20, 2021. We also know that the House of Representatives will remain under the control of the Democratic party. And, with the results of the January 5, 2021 Georgia Senate run-off races (pending state certification), we also know that Vice-President elect Kamala Harris will be the deciding vote in the Senate on any 50-50 splits. Historically, from 1950 through 2019, a Democratic Congress generated an average annual return of 10.7% for the S&P 500® Index, compared to 13.4% for a Republican Congress, according to LPL Research and Bloomberg. Stay tuned.

By the time you read this, the U.S. Food and Drug Administration will have approved at least two COVID-19 vaccines for emergency use. Both these vaccines were found to have an efficacy rate of approximately 95% on humans in late clinical testing, which, in my opinion, should give people willing to take the vaccine another level of confidence. The fact that it only took 8-9 months for these vaccines to reach the public is astounding. History tells us that it should have taken at least 18 months, and even that would have been hailed as a major accomplishment. This achievement is another example of the kind of cutting-edge ingenuity brought to bear in the U.S. day in and day out during the COVID-19 pandemic.

We are encouraged about the prospects for the economy and the markets, but investors should be prepared to weather some volatility until the COVID-19 pandemic is better contained. As always, we encourage investors to stay the course!

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

Sincerely,

James A. Bowen

Chairman of the Board of Trustees

Chief Executive Officer of First Trust Advisors L.P.

Most recent distribution paid or declared through 11/30/2020. Subject to change in the future.
Distribution rates are calculated by annualizing the most recent distribution paid or declared through the report date and then dividing by Common Share Price or NAV, as applicable, as of 11/30/2020. Subject to change in the future.
Total return is based on the combination of reinvested dividend, capital gain, and return of capital distributions, if any, at prices obtained by the Dividend Reinvestment Plan and changes in NAV per share for NAV returns and changes in Common Share Price for market value returns. Total returns do not reflect sales load and are not annualized for periods of less than one year. Past performance is not indicative of future results.
The blended index consists of the following: PHLX Utility Sector Index (50%) and Alerian MLP Total Return Index (50%). The Blended Index reflects the diverse allocation of companies engaged in the energy infrastructure sector in the Fund's portfolio. The indexes do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the performance shown. Indexes are unmanaged and an investor cannot invest directly in an index. The Blended Index returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Index for each period shown above.

Commentary

First Trust Energy Infrastructure Fund

The investment objective of the Fund is to seek a high level of total return with an emphasis on current distributions paid to shareholders. The Fund pursues its investment objective by investing primarily in securities of companies engaged in the energy infrastructure sector. These companies principally include publicly-traded master limited partnerships ("MLPs") and limited liability companies taxed as partnerships, MLP affiliates, YieldCos, pipeline companies, utilities and other infrastructure-related companies that derive at least 50% of their revenues from operating, or providing services in support of, infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "Energy Infrastructure Companies"). For purposes of the Fund's investment objective, total return includes capital appreciation of, and all distributions received from, securities in which the Fund invests, taking into account the varying tax characteristics of such securities. Under normal market conditions, the Fund invests at least 80% of its managed assets (total asset value of the Fund minus the sum of the Fund's liabilities other than the principal amount of borrowings) in securities of Energy Infrastructure Companies. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.

Market Recap

As measured by the Alerian MLP Total Return Index ("AMZX") and the PHLX Utility Sector Index ("UTY"), the total return for the 12-month period ended November 30, 2020 was -24.50% and 5.33%, respectively. While in the short term, share appreciation of Energy Infrastructure Companies can be volatile, EIP believes that over the longer term, such share appreciation will approximate growth in annual cash distributions and dividends per share.

Performance Analysis

On a net asset value ("NAV") basis, the Fund provided a total return1 of -19.31%, including the reinvestment of distributions, for the 12-month period ended November 30, 2020. This compares, according to collected data, to a -4.66% return for a blended index consisting of the UTY (50%) and the AMZX (50%) (the "Blended Index"). Unlike the Fund, the Blended Index does not incur fees and expenses. On a market value basis, the Fund had a total return, including the reinvestment of distributions, of -25.80% for the same period. At the end of the same period, the Fund's market price per share was $10.52, while the NAV per Common Share was

1 Total return is based on the combination of reinvested dividend, capital gain and return of capital distributions, if any, at prices obtained by the Dividend Reinvestment Plan and changes in NAV per share for NAV returns and changes in Common Share Price for market value returns. Total returns do not reflect sales load and are not annualized for periods of less than one year. Past performance is not indicative of future results.

Annual Report

November 30, 2020 (Unaudited)

$12.47, a discount of -15.64%. As of November 30, 2019, the Fund's market price per share was $15.45, while the NAV per Common Share was $16.84, a discount of -8.25%.

The Fund's regular monthly Common Share distribution was $0.11 for the period December 2019 through April 2020. A monthly distribution of $0.0625 was declared for the period May 2020 through November 2020. The distribution reduction results from three factors that have lowered the Fund's distributable cash flow: 1) a reduction in Fund assets as a result of portfolio sales to reduce Fund leverage to maintain compliance with applicable leverage limits, 2) reduced distribution payments from portfolio companies lowering distribution payout ratios and 3) anticipated changes to the portfolio composition including the Fund's use of leverage and reductions to income from the covered call strategy.

For the 12-month period ended November 30,2020, the Fund's NAV underperformed the -4.66% return of the Blended Index by 1,465 basis points ("bps"). The Fund's underperformance was partially driven by overweight positions in pipeline corporations that underperformed the UTY, while the remaining underperformance was attributable to leverage that had a negative effect on the performance of the Fund during the reporting period. Derivatives also had a negative impact on the performance of the Fund over the reporting period. The Fund established a committed facility agreement with The Bank of Nova Scotia with a current maximum commitment amount of $66,000,000. The Fund uses leverage because its portfolio managers believe that, over time, leverage can enhance total return for common shareholders. However, the use of leverage can also increase the volatility of the NAV and, therefore, the share price. During the reporting period, prices of securities held by the Fund declined and the effect of changes in common share NAV and common share total return loss was magnified by the use of leverage. Unlike the Fund, AMZX and UTY are not leveraged.

Market and Fund Outlook

The first calendar quarter of 2020 was dominated by the dramatic price declines in the crude oil market due to Saudi and Russian production decisions coupled with the demand shock related to the coronavirus ("COVID-19") pandemic. These weak market conditions drove a 21% decline in the AMZX between January 1 and February 28, 2020, then panic took hold in March driving another 59% decline by March 18. (Source: Bloomberg) Our analysis indicates that forced selling by levered closed-end MLP funds was approximately $4.3 billion and outflows from open-end funds were approximately $0.9 billion in a four-week period. This is nearly $1 billion more than the selling that occurred over a 9-month period in 2015-2016 due to outflows and de-leveraging when oil prices corrected from over $100 per barrel, but on assets that were nearly three times as large as today.

Despite a second quarter rally off the lows of the first quarter, stock price performance of the AMZX and the energy companies in the S&P 500® Index turned negative again in the third quarter of 2020 as near-term fundamentals for crude oil remained uncertain. At the end of the third quarter of 2020, the price of crude oil was still down 34% year-to-date and drilling activity remained near the all-time lows set in August of 2020. Crude oil production was trending lower in most basins by the end of the third quarter of 2020 despite rebounding in the second quarter as shut-in production was brought back online. Second quarter announcements by oil and gas producers to cut spending and lay off staff was followed by several third quarter merger announcements.

Slowing investment and negative sentiment in upstream energy driven by COVID-19- related declines in demand have given rise to a narrative that all conventional energy businesses are in decline; this is simply wrong. It is true that coal will likely continue to decline. We believe crude oil and refined products demand will be slow to fully recover from the pandemic and their long-term growth is threatened by electrification of large parts of the transportation system, but these businesses represent the minority of our portfolio. And the companies in our portfolio exposed to these businesses are trading at dividend yields and valuations that make their expected rates of return the highest in our portfolio.

On the other hand, in EIP's opinion, the outlook for electricity and natural gas, the majority of the portfolio, remains strong and is increasingly aligned with public sentiment and environmental policy. Cheaper sources of cleaner electricity continue to substitute for coal which is likely to continue to decline as an energy source, in our view, and to which we have no portfolio earnings exposure. EIP believes electric and natural gas utilities are experiencing attractive rates of earnings growth as they invest capital to incorporate cheaper, cleaner, safer, and more reliable sources of energy. In our view, the network utilities can increase the value of these new technologies by integrating them into an intelligent system of shared resources much the way information networks like cloud computing and the new retail intermediaries like Amazon and eBay are doing for those parts of the economy. We believe the transition to a shared resource network favors their incumbency and existing rights of way, which provides energy cheaper to customers than disconnecting from these networks by "cutting the cord".

EIP is optimistic about the technological breakthroughs in energy and invests in companies like renewable developers and network utilities that benefit from the lower cost and higher performance of renewables, batteries, and other new grid-related innovations. But EIP is not a venture capitalist, companies in the Fund's portfolio must have a track record of profitability and a willingness to share some portion of that profitability through distributions. While the names in the portfolio change over time, the strategy and the sources of earnings stability and growth remain the same: investing in monopoly infrastructure that provides the low-cost way of shipping the lowest cost form of energy.

During the year ended November 30, 2016, the Fund received a reimbursement from the sub-advisor in the amount of $1,600 in connection with a trade error, which represents less than $0.01 per share. Since the sub-advisor reimbursed the Fund, there was no effect on the total return.
Total return is based on the combination of reinvested dividend, capital gain and return of capital distributions, if any, at prices obtained by the Dividend Reinvestment Plan, and changes in net asset value per share for net asset value returns and changes in Common Share Price for market value returns. Total returns do not reflect sales load and are not annualized for periods of less than one year. Past performance is not indicative of future results.
Calculated by subtracting the Fund's total liabilities (not including the loans outstanding) from the Fund's total assets, and dividing by the outstanding loans balance in 000's.

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020

1. Organization

First Trust Energy Infrastructure Fund (the "Fund") is a non-diversified,closed-end management investment company organized as a Massachusetts business trust on February 22, 2011, and is registered with the Securities and Exchange Commission ("SEC") under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund trades under the ticker symbol "FIF" on the New York Stock Exchange ("NYSE").

The Fund's investment objective is to seek a high level of total return with an emphasis on current distributions paid to shareholders. The Fund pursues its investment objective by investing primarily in securities of companies engaged in the energy infrastructure sector. These companies principally include publicly-traded master limited partnerships and limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, YieldCos, pipeline companies, utilities and other infrastructure-related companies that derive at least 50% of their revenues from operating, or providing services in support of, infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "Energy Infrastructure Companies"). For purposes of the Fund's investment objective, total return includes capital appreciation of, and all distributions received from, securities in which the Fund invests, taking into account the varying tax characteristics of such securities. Under normal market conditions, the Fund invests at least 80% of its managed assets (total asset value of the Fund minus the sum of the Fund's liabilities other than the principal amount of borrowings) in securities of Energy Infrastructure Companies. There can be no assurance that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.

2. Managed Distribution Policy

The Board of Trustees of the Fund has approved a managed distribution policy for the Fund (the "Plan") in reliance on exemptive relief received from the SEC that permits the Fund to make periodic distributions of long-term capital gains as frequently as monthly each tax year. Under the Plan, the Fund currently intends to continue to pay a recurring monthly distribution in the amount of $0.0625 per Common Share that reflects the distributable cash flow of the Fund. A portion of this monthly distribution may include realized capital gains. This may result in a reduction of the long-term capital gain distribution necessary at year end by distributing realized capital gains throughout the year. The annual distribution rate is independent of the Fund's performance during any particular period. Accordingly, you should not draw any conclusions about the Fund's investment performance from the amount of any distribution or from the terms of the Plan. The Board of Trustees may amend or terminate the Plan at any time without prior notice to shareholders.

3. Significant Accounting Policies

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

A. Portfolio Valuation

The net asset value ("NAV") of the Common Shares of the Fund is determined daily as of the close of regular trading on the 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. Foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund's NAV per Common Share is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses, the value of call options written (sold), dividends declared but unpaid, and any borrowings of the Fund) by the total number of Common Shares outstanding.

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

Common stocks, MLPs 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.

Page 16

Notes to Financial Statements (Continued)

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020

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.

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

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.

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

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Fund'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 the Fund's NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security's fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:

the type of security;
the size of the holding;
the initial cost of the security;
transactions in comparable securities;
price quotes from dealers and/or third-party pricing services;
relationships among various securities;
information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
an analysis of the issuer's financial statements; and
the existence of merger proposals or tender offers that might affect the value of the security.

If the securities in question are foreign securities, the following additional information may be considered:

the value of similar foreign securities traded on other foreign markets;
ADR trading of similar securities;
closed-endfund or exchange-traded fund trading of similar securities;
foreign currency exchange activity;
the trading prices of financial products that are tied to baskets of foreign securities;
factors relating to the event that precipitated the pricing problem;
whether the event is likely to recur; and
whether the effects of the event are isolated or whether they affect entire markets, countries or regions.

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

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.
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.

Page 17

Notes to Financial Statements (Continued)

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020

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.

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).

1. Inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 - Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity's own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value the Fund's investments as of November 30, 2020, is included with the Fund's Portfolio of Investments.

B. Option Contracts

The Fund is subject to equity price risk in the normal course of pursuing its investment objective and may write (sell) options to hedge against changes in the value of equities. Also, the Fund seeks to generate additional income, in the form of premiums received, from writing (selling) the options. The Fund may write (sell) covered call or put options ("options") on all or a portion of the MLPs and common stocks held in the Fund's portfolio as determined to be appropriate by Energy Income Partners, LLC ("EIP" or the "Sub-Advisor"). The number of options the Fund can write (sell) is limited by the amount of MLPs and common stocks the Fund holds in its portfolio. The Fund will not write (sell) "naked" or uncovered options. When the Fund writes (sells) an option, an amount equal to the premium received by the Fund is included in "Options written, at value" on the Fund's Statement of Assets and Liabilities. Options are marked-to-market daily and their value will be affected by changes in the value and dividend rates of the underlying equity securities, changes in interest rates, changes in the actual or perceived volatility of the securities markets and the underlying equity securities and the remaining time to the options' expiration. The value of options may also be adversely affected if the market for the options becomes less liquid or trading volume diminishes.

The options that the Fund writes (sells) will either be exercised, expire or be canceled pursuant to a closing transaction. If the price of the underlying equity security exceeds the option's exercise price, it is likely that the option holder will exercise the option. If an option written (sold) by the Fund is exercised, the Fund would be obligated to deliver the underlying equity security to the option holder upon payment of the strike price. In this case, the option premium received by the Fund will be added to the amount realized on the sale of the underlying security for purposes of determining gain or loss and is included in "Net realized gain (loss) on investments" on the Statement of Operations. If the price of the underlying equity security is less than the option's strike price, the option will likely expire without being exercised. The option premium received by the Fund will, in this case, be treated as short-term capital gain on the expiration date of the option. The Fund may also elect to close out its position in an option prior to its expiration by purchasing an option of the same series as the option written (sold) by the Fund. Gain or loss on options is presented separately as "Net realized gain (loss) on written options" on the Statement of Operations.

The options that the Fund writes (sells) give the option holder the right, but not the obligation, to purchase a security from the Fund at the strike price on or prior to the option's expiration date. The ability to successfully implement the writing (selling) of covered call options depends on the ability of the Sub-Advisor to predict pertinent market movements, which cannot be assured. Thus, the use of options may require the Fund to sell portfolio securities at inopportune times or for prices other than current market value, which may limit the amount of appreciation the Fund can realize on an investment, or may cause the Fund to hold a security that it might otherwise sell. As the writer (seller) of a covered option, the Fund foregoes, during the option's life, the opportunity to profit from increases in the market value of the security covering the option above the sum of the premium and the strike price of the option, but has retained the risk of loss should the price of the underlying security decline. The writer (seller) of an option has no control over the time when it may be required to fulfill its obligation as a writer (seller) of the option. Once an option writer (seller) has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security to the option holder at the exercise price.

Over-the-counter options have the risk of the potential inability of counterparties to meet the terms of their contracts. The Fund's maximum equity price risk for purchased options is limited to the premium initially paid. In addition, certain risks may arise upon entering into option contracts including the risk that an illiquid secondary market will limit the Fund's ability to close out an option contract prior to the expiration date and that a change in the value of the option contract may not correlate exactly with changes in the value of the securities hedged.

C. Swap Agreements

The Fund may enter into total return equity swap and interest rate swap agreements. A swap is a financial instrument that typically involves the exchange of cash flows between two parties ("Counterparties") on specified dates (settlement dates) where the cash flows are based on agreed upon prices, rates, etc. Payment received or made by the Fund for interest rate swaps are recorded on the Statement of Operations as "Net realized gain (loss) on swap contracts." When an interest rate swap is terminated, the Fund will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Fund's basis in the contract, if any. Generally, the basis of the contracts, if any, is the premium received or paid. Swap agreements are individually negotiated and involve the risk of the potential inability of the Counterparties to meet the terms of the agreement. In connection with these agreements, cash and securities may be identified as collateral in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default under the swap agreement or bankruptcy/insolvency of a party to the swap agreement. In the event of a default by a Counterparty, the Fund will seek withdrawal of the collateral and may incur certain costs exercising its rights with respect to the collateral. If a Counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Fund may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Fund may obtain only limited recovery or may obtain no recovery in such circumstances.

Swap agreements may increase or decrease the overall volatility of the investments of the Fund. The performance of swap agreements may be affected by changes in the specific interest rate, security, currency, or other factors that determine the amounts of payments due to and from the Fund. The Fund's maximum interest rate risk to meet its future payments under swap agreements outstanding at November 30, 2020, is equal to the total notional amount as shown on the Portfolio of Investments. The notional amount represents the U.S. dollar value of the contract as of the day of the opening transaction or contract reset. When the Fund enters into a swap agreement, any premium paid is included in "Swap contracts, at value" on the Statement of Assets and Liabilities.

The Fund held interest rate swap agreements at November 30, 2020 to hedge against changes in borrowing rates under the Fund's credit agreement. An interest rate swap agreement involves the Fund's agreement to exchange a stream of interest payments for another party's stream of cash flows. Interest rate swaps do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that the Fund is contractually obligated to make.

In November 2020, ICE Benchmark Administration Limited (IBA), the administrator of the London Interbank Offered Rates ("LIBOR") announced a consultation process beginning in December 2020 and ending in January 2021 regarding its intention to cease the publication of LIBOR rates. The IBA intends to cease the publication of the one week and two month USD LIBOR settings as well as LIBOR settings in all other currencies immediately following the LIBOR publication on December 31, 2021, and to cease the publication of the remaining USD LIBOR settings (overnight, one month, three month, six month, and twelve month) immediately following the LIBOR publication on June 30, 2023. Follow-up announcements by the Financial Conduct Authority ("FCA") and US Regulators support the IBA's intention and include supervisory guidance encouraging parties to adopt fallback LIBOR rates in existing arrangements as soon as practical and to cease entering into new arrangements that use LIBOR as a reference rate no later than December 31, 2021.

In the United States, the Alternative Reference Rates Committee (the "ARRC"), a group of market participants convened by the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York in cooperation with other federal and state government agencies, has since 2014 undertaken efforts to identify U.S. dollar reference interest rates as alternatives to LIBOR and to facilitate the mitigation of LIBOR-related risks. In June 2017, the ARRC identified the Secured Overnight Financing Rate ("SOFR"), a broad measure of the cost of cash overnight borrowing collateralized by U.S. Treasury securities, as the preferred alternative for U.S. dollar LIBOR. The Federal Reserve Bank of New York began daily publishing of SOFR in April 2018.

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

D. Restricted Cash

Restricted cash includes cash on deposit with other banks or brokers that is legally restricted as to the withdrawal and primarily serves as collateral for open swap contracts. The Fund presents restricted cash activity within "Increase in cash and cash segregated as collateral for open swap contracts" and as part of "Cash and cash segregated as collateral for open swap contracts at beginning of period" and "Cash and cash segregated as collateral for open swap contracts at end of period" in the Statement of Cash Flows, along with a reconciliation of those balances in the Statement of Assets and Liabilities. At November 30, 2020, the Fund had $4,415,294 in restricted cash associated with interest rate swap agreements as presented on the Statement of Assets and Liabilities as "Cash segregated as collateral for open swap contracts."

E. Securities Transactions and Investment Income

Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income is recorded daily on the accrual basis. The Fund will rely to some extent on information provided by MLPs, which is not necessarily timely, to estimate taxable income allocable to the MLP units held in the Fund's portfolio.

Distributions received from the Fund's investments in MLPs generally are comprised of return of capital and investment income. The Fund records estimated return of capital and investment income based on historical information available from each MLP. These estimates may subsequently be revised based on information received from the MLPs after their tax reporting periods are concluded. For the fiscal year ended November 30, 2020, distributions of $10,643,704 received from MLPs have been reclassified as return of capital. The cost basis of applicable MLPs has been reduced accordingly.

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

F. Foreign Currency

The books and records of the Fund are maintained in U.S. dollars. Foreign currencies, investments and other assets and liabilities are translated into U.S. dollars at the exchange rates prevailing at the end of the period. Purchases and sales of investments and items of income and expense are translated on the respective dates of such transactions. Unrealized gains and losses on assets and liabilities, other than investments in securities, which result from changes in foreign currency exchange rates have been included in "Net change in unrealized appreciation (depreciation) on foreign currency translation" on the Statement of Operations. Unrealized gains and losses on investments in securities which result from changes in foreign exchange rates are included with fluctuations arising from changes in market price and are included in "Net change in unrealized appreciation (depreciation) on investments" on the Statement of Operations. Net realized foreign currency gains and losses include the effect of changes in exchange rates between trade date and settlement date on investment security transactions, foreign currency transactions and interest and dividends received and are included in "Net realized gain (loss) on foreign currency transactions" on the Statement of Operations. The portion of foreign currency gains and losses related to fluctuations in exchange rates between the initial purchase settlement date and subsequent sale trade date is included in "Net realized gain (loss) on investments" on the Statement of Operations.

G. Offsetting on the Statement 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 Statement 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 Fund does not offset financial assets and financial liabilities that are subject to master netting arrangements ("MNAs") or similar agreements on the Statement 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.

At November 30, 2020, derivative assets and liabilities (by type) on a gross basis are as follows:

H. Dividends and Distributions to Shareholders

The Fund intends to pay holders of its Common Shares a recurring monthly distribution that reflects the distributable cash flow of the Fund. Distributions will automatically be reinvested into additional Common Shares pursuant to the Fund's Dividend Reinvestment Plan unless cash distributions are elected by the shareholder.

Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Fund and have no impact on net assets or NAV per Common 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 point in the future. Permanent differences incurred during the year ended November 30, 2020, primarily as a result of differing book and tax treatments on the sale of MLP investments, have been reclassified at year end to reflect an increase in accumulated net investment income (loss) of $4,181,808, a decrease in accumulated net realized gain (loss) on investments of $3,838,387 and a decrease to paid-in capital of $343,421. Accumulated distributable earnings (loss) consists of accumulated net investment income (loss), accumulated net realized gain (loss) on investments, and unrealized appreciation (depreciation) on investments. Net assets were not affected by these reclassifications.

The tax character of distributions paid during the fiscal years ended November 30, 2020 and 2019 is as follows:

Distributions paid from:		2020		2019
Ordinary income . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .	$	8,085,491	$	5,265,386

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

The Fund intends to utilize provisions of the federal income tax laws, which allow it to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Fund is subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At November 30, 2020, the Fund had $29,397,744 of non-expiring capital loss carryforwards for federal income tax purposes.

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 November 30, 2020, the Fund did not incur any net ordinary losses.

The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. Taxable years ended 2017, 2018, 2019, and 2020 remain open to federal and state audit. As of November 30, 2020, management has evaluated the application of these standards to the Fund, and has determined that no provision for income tax is required in the Fund's financial statements for uncertain tax positions.

J. Expenses

The Fund will pay all expenses directly related to its operations.

4. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements

First Trust, the investment advisor to the Fund, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the ongoing monitoring of the Fund's investment portfolio, managing the Fund's business affairs and providing certain administrative services necessary for the management of the Fund. For these investment management services, First Trust is entitled to a monthly fee calculated at an annual rate of 1.00% of the Fund's Managed Assets (the average daily total asset value of the Fund minus the sum of the Fund's liabilities other than the principal amount of borrowings). First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250.

EIP serves as the Fund's sub-advisor and manages the Fund's portfolio subject to First Trust's supervision. The Sub-Advisor receives a monthly sub-advisory fee calculated at an annual rate of 0.50% of the Fund's Managed Assets that is paid by First Trust from its investment advisory fee.

First Trust Capital Partners, LLC ("FTCP"), an affiliate of First Trust, owns, through a wholly-owned subsidiary, a 15% ownership interest in each of EIP and EIP Partners, LLC, an affiliate of EIP.

BNY Mellon Investment Servicing (US) Inc. ("BNYM IS") serves as the Fund's transfer agent in accordance with certain fee arrangements. As transfer agent, BNYM IS is responsible for maintaining shareholder records for the Fund. The Bank of New York Mellon ("BNYM") serves as the Fund's administrator, fund accountant, and custodian in accordance with certain fee arrangements. As administrator and fund accountant, BNYM is responsible for providing certain administrative and accounting services to the Fund,

Page 22

Notes to Financial Statements (Continued)

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020

including maintaining the Fund's books of account, records of the Fund's securities transactions, and certain other books and records. As custodian, BNYM is responsible for custody of the Fund's assets. BNYM IS and BNYM are subsidiaries of The Bank of New York Mellon Corporation, a financial holding company.

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

5. Purchases and Sales of Securities

The cost of purchases and proceeds from sales of securities, excluding short-term investments, for the fiscal year ended November 30, 2020, were $232,090,851 and $303,704,038, respectively.

6. Derivative Transactions

The following table presents the types of derivatives held by the Fund at November 30, 2020, the primary underlying risk exposure and the location of these instruments as presented on the Statement of Assets and Liabilities.

				Asset Derivatives			Liability Derivatives
Derivative	Risk	Statement of Assets and			Statement of Assets and
Instrument		Exposure		Liabilities Location		Value	Liabilities Location		Value

Written Options		Equity Risk		-		$ -		Options written, at value		$ 1,541,597
Interest Rate Swap Agreements	Interest Rate Risk	Swap contracts, at value	82		Swap contracts, at value	3,023,959

The following table presents the amount of net realized gain (loss) and change in net unrealized appreciation (depreciation) recognized for the fiscal year ended November 30, 2020, on derivative instruments, as well as the primary underlying risk exposure associated with each instrument.

Statement of Operations Location

Equity Risk Exposure
Net realized gain (loss) on written options contracts	$	3,447,528
Net change in unrealized appreciation (depreciation) on written options contracts		(1,507,578)
Interest Rate Risk Exposure
Net realized gain (loss) on swap contracts	$	(948,417)
Net change in unrealized appreciation (depreciation) on swap contracts		(1,270,077)

During the fiscal year ended November 30, 2020, the premiums for written options opened were $4,650,718, and the premiums for written options closed, exercised and expired were $5,678,110.

The average notional value of interest rate swaps was $54,369,077 for the fiscal year ended November 30, 2020.

The Fund does not have the right to offset financial assets and liabilities related to option contracts on the Statement of Assets and Liabilities.

7. Borrowings

The Fund has a credit agreement with The Bank of Nova Scotia. The credit agreement provides a secure line of credit for the Fund where Fund assets are pledged against advances made to the Fund. The maximum commitment amount is $66,000,000. Prior to April 30, 2020, the maximum commitment amount was $130,000,000. The borrowing rate is the applicable LIBOR rate plus 95 basis points. Prior to October 23, 2020, the borrowing rate was the applicable LIBOR rate plus 80 basis points. Under the credit agreement, the Fund pays a commitment fee of 0.25% when the loan balance is less than 75% of the maximum commitment. The borrowings are categorized as Level 2 within the fair value hierarchy. The average amount outstanding for the fiscal year ended November 30, 2020 was $65,482,240, with a weighted average interest rate of 1.76%. As of November 30, 2020, the Fund had outstanding borrowings of

Page 23

Notes to Financial Statements (Continued)

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020

$55,300,000 under this credit agreement, which approximates fair value. The high and low annual interest rates for the fiscal year ended November 30, 2020, were 2.56% and 0.95%, respectively. The interest rate at November 30, 2020 was 1.08%. The interest and fees are included in "Interest and fees on loans" on the Statement of Operations.

8. Indemnification

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

9. Industry Concentration Risk

Under normal market conditions, the Fund invests at least 80% of its Managed Assets in securities of Energy Infrastructure Companies. Given this industry concentration, the Fund is more susceptible to adverse economic or regulatory occurrences affecting that industry than an investment company that is not concentrated in a single industry. Energy Infrastructure Company issuers may be subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage costs associated with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors.

10. Subsequent Events

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

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of First Trust Energy Infrastructure Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of First Trust Energy Infrastructure Fund (the "Fund"), including the portfolio of investments, as of November 30, 2020, the related statements of operations and cash flows for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of November 30, 2020, and the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

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

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of November 30, 2020, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion.

Dividend Reinvestment Plan

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund's Dividend Reinvestment Plan (the "Plan"), unless you elect, by written notice to the Fund, to receive cash distributions, all dividends, including any capital gain distributions, on your Common Shares will be automatically reinvested by BNY Mellon Investment Servicing (US) Inc. (the "Plan Agent"), in additional Common Shares under the Plan. If you elect to receive cash distributions, you will receive all distributions in cash paid by check mailed directly to you by the Plan Agent, as the dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows:

If Common Shares are trading at or above net asset value ("NAV") at the time of valuation, the Fund will issue new shares at a price equal to the greater of (i) NAV per Common Share on that date or (ii) 95% of the market price on that date.
If Common Shares are trading below NAV at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the NYSE or elsewhere, for the participants' accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases.
Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date except where temporary curtailment or suspension of purchases is necessary to comply with federal securities laws. Interest will not be paid on any uninvested cash payments.

You may elect to opt-out of or withdraw from the Plan at any time by giving written notice to the Plan Agent, or by telephone at

340-1104,in accordance with such reasonable requirements as the Plan Agent and the Fund may agree upon. If you withdraw or the Plan is terminated, you will receive a certificate for each whole share in your account under the Plan, and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions.

The Plan Agent maintains all Common Shareholders' accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common Shares in your account will be held by the Plan Agent in non-certificated form. The Plan Agent will forward to each participant any proxy solicitation material and will vote any shares so held only in accordance with proxies returned to the Fund. Any proxy you receive will include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions. Capital gains and income are realized although cash is not received by you. Consult your financial advisor for more information.

If you hold your Common Shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained by writing BNY Mellon Investment Servicing (US) Inc., 301 Bellevue Parkway, Wilmington, Delaware 19809.

The number of votes cast in favor of Mr. Keith was 15,153,649 and the number of votes withheld was 589,142. James A. Bowen, Richard E. Erickson, Thomas R. Kadlec and Niel B. Nielson are the other current and continuing Trustees.

Amended and Restated By-Laws

On October 19, 2020, after a thorough review, and consistent with the interests of the Fund, the Board of Trustees adopted Amended and Restated By-Laws, dated October 19, 2020 (the "Amended and Restated By-Laws").

Among other changes, the Amended and Restated By-Laws contain new timelines for advance notice of shareholder proposals and nominations to be brought before a meeting of shareholders. Further, the Amended and Restated By-Laws require compliance with certain procedural and informational requirements in connection with the advance notice of shareholder proposals or nominations, including a requirement to provide certain information about the proponent and the proposal, or in the case of a nomination, the nominee. Any shareholder considering making a nomination or proposal should carefully review and comply with those provisions of the Amended and Restated By-Laws.

The Amended and Restated By-Laws contain certain changes contemplating the nomination, qualification and procedures for the election of Trustees. The Amended and Restated By-Laws require additional information from a nominee for Trustee, and if requested, require a nominee to sit for an interview with the Board, to determine whether the nominee has the ability to critically review, evaluate, question and discuss information provided to the Board, and interact effectively with the other Trustees and management of the Fund, among other parties. Additionally, the Amended and Restated By-Laws include qualifications and eligibility requirements for Trustees.

The Amended and Restated By-Laws provide that in the instance in which the number of persons nominated for election as Trustee exceeds the number of Trustees to be elected, the affirmative vote of a majority of shares outstanding and entitled to vote in such an election is required to elect a Trustee. In all other elections, the plurality standard pursuant to which Trustees are elected will remain.

The Amended and Restated By-Laws also include provisions (the "Control Share Provisions") pursuant to which, in summary, a shareholder who obtains beneficial ownership of common shares of the Fund in a "Control Share Acquisition" may exercise voting rights with respect to such shares only to the extent the authorization of such voting rights is approved by other shareholders of the Fund. The Control Share Provisions are primarily intended to seek to protect the interests of the Fund and its long-term shareholders by limiting the risk that the Fund will become subject to undue influence by opportunistic traders pursuing short-term agendas adverse to the best interests of the Fund and its long-term shareholders. The Control Share Provisions do not eliminate voting rights for common shares acquired in Control Share Acquisitions, but rather entrust the Fund's other "non-interested" shareholders with determining whether to approve the authorization of the voting rights of the person acquiring such shares.

Subject to various conditions and exceptions, the Control Share Provisions define a "Control Share Acquisition" to include an acquisition of common shares that, but for the Control Share Provisions, would give the beneficial owner upon the acquisition of such shares the ability to exercise voting power in the election of Trustees of the Fund in any of the following ranges:

one-tenthor more, but less than one-fifth of all voting power;
one-fifthor more, but less than one-third of all voting power;
one-thirdor more, but less than a majority of all voting power; or
a majority or more of all voting power.

Share acquisitions that pre-date the adoption of the Amended and Restated By-Laws are excluded from the definition of Control Share Acquisition. However, such shares are included in assessing whether any subsequent share acquisition exceeds the above thresholds.

Subject to certain conditions and procedural requirements set forth in the Control Share Provisions, including the delivery of a "Control Share Acquisition Statement" to the Fund setting forth certain required information, a shareholder who obtains or proposes to obtain beneficial ownership of common shares in a Control Share Acquisition may demand a special meeting of shareholders for the purpose of considering whether the voting rights of such acquiring person with respect to such shares shall be authorized. If a shareholder who obtains or proposes to obtain beneficial ownership of shares in a Control Share Acquisition does not demand a special meeting of Fund shareholders, consideration of the authorization of voting rights of such shares shall be presented at the Fund's next annual or special meeting of shareholders.

This discussion is only a high-level summary of certain aspects of the Amended and Restated By-Laws, and is qualified in its entirety by reference to the Amended and Restated By-Laws. Shareholders should refer to the Amended and Restated By-Laws for more information. A copy of the Amended and Restated By-Laws can be found in the Current Report on Form 8-K filed by the Fund with the Securities and Exchange Commission on October 20, 2020, which is available at www.sec.gov, and may also be obtained by writing to the Secretary of the Fund at the Fund's principal executive office.

Advisory and Sub-Advisory Agreements

Board Considerations Regarding Approval of Continuation of Investment Management and Investment Sub-Advisory Agreements

The Board of Trustees of First Trust Energy Infrastructure Fund (the "Fund"), including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement (the "Advisory Agreement") between the Fund and First Trust Advisors L.P. (the "Advisor") and the Investment Sub Advisory Agreement (the "Sub Advisory Agreement" and together with the Advisory Agreement, the "Agreements") among the Fund, the Advisor and Energy Income Partners, LLC (the "Sub-Advisor"). The Board approved the continuation of the Agreements for a one-year period ending June 30, 2021 at a meeting held on June 8, 2020. The Board determined that the continuation of the Agreements 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, the Board considered its duties under the Investment Company Act of 1940, as amended (the "1940 Act"), as well as under the general principles of state law, in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; the fiduciary duty of investment advisors with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards have fulfilled their duties; and the factors to be considered by the Board in voting on such agreements. At meetings held on May 11, 2020 and June 8, 2020, the Board, including the Independent Trustees, reviewed materials provided by the Advisor and the Sub-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 and the Sub-Advisor to the Fund (including the relevant personnel responsible for these services and their experience); the advisory fee rate payable by the Fund and the sub-advisory fee rate 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 and the Sub-Advisor; the expense ratio of the Fund as compared to expense ratios of the funds in the Fund's Expense Group and Expense Universe; performance information for the Fund, including comparisons of the Fund's performance to that of one or more relevant benchmark indexes and to that of a performance group of funds and a broad performance universe of funds (the "Performance Universe"), each assembled by Broadridge; the nature of expenses incurred in providing services to the Fund and the potential for the Advisor and the Sub-Advisor to realize economies of scale, if any; profitability and other financial data for the Advisor; financial data for the Sub-Advisor; any fall out benefits to the Advisor and its affiliate, First Trust Capital Partners, LLC ("FTCP"), and the Sub-Advisor; and information on the Advisor's and the Sub-Advisor's compliance programs. The Board reviewed initial materials with the Advisor at the meeting held on May 11, 2020, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the

Page 28

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020 (Unaudited)

Advisor and the Sub-Advisor. Following the May meeting, counsel to the Independent Trustees, on behalf of the Independent Trustees, requested certain clarifications and supplements to the materials provided, and the information provided in response to those requests was considered at an executive session of the Independent Trustees and their counsel held prior to the June 8, 2020 meeting, as well as at the meeting held that day. The Board considered supplemental information provided by the Advisor and the Sub-Advisor on the operations of the Advisor and the Sub-Advisor, respectively, and the performance of the Fund since the onset of the COVID-19 pandemic. The Board applied its business judgment to determine whether the arrangements between the Fund and the Advisor and among the Fund, the Advisor and the Sub-Advisor continue to be reasonable business arrangements from the 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 the Fund knowing that the Advisor and the Sub-Advisor manage the Fund.

In reviewing the Agreements, the Board considered the nature, extent and quality of the services provided by the Advisor and the Sub-Advisor under the Agreements. With respect to the Advisory Agreement, the Board considered that the Advisor is responsible for the overall management and administration of the Fund and reviewed all of the services provided by the Advisor to the Fund, including the oversight of the Sub-Advisor, as well as the background and experience of the persons responsible for such services. The Board noted that the Advisor oversees the Sub-Advisor'sday-to-day management of the Fund's investments, including portfolio risk monitoring and performance review. 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, the Sub-Advisor's and the Fund's compliance with the 1940 Act, as well as the Fund's compliance with its investment objective, policies and restrictions. The Board also considered a report from the Advisor with respect to its risk management functions related to the operation of the Fund. Finally, as part of the Board's consideration of the Advisor's services, the Advisor, in its written materials and at the May 11, 2020 meeting, described to the Board the scope of its ongoing investment in additional infrastructure and personnel to maintain and improve the quality of services provided to the Fund and the other funds in the First Trust Fund Complex. With respect to the Sub-Advisory Agreement, in addition to the written materials provided by the Sub-Advisor, at the June 8, 2020 meeting, the Board also received a presentation from representatives of the Sub-Advisor discussing the services that the Sub-Advisor provides to the Fund, including the Sub-Advisor'sday-to-day management of the Fund's investments. In considering the Sub-Advisor's management of the Fund, the Board noted the background and experience of the Sub-Advisor's portfolio management team. 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 Fund by the Advisor and the Sub-Advisor under the Agreements have been and are expected to remain satisfactory and that the Sub-Advisor, under the oversight of the Advisor, has managed the Fund consistent with its investment objective, policies and restrictions.

The Board considered the advisory and sub-advisory fee rates payable under the Agreements for the services provided. The Board noted that the sub-advisory fee is paid by the Advisor from its advisory fee. The Board received and reviewed information showing the advisory fee rates and expense ratios of the peer funds in the Expense Group, as well as advisory and unitary fee rates charged by the Advisor and the Sub-Advisor to other fund and non-fund clients, as applicable. With respect to the Expense Group, the Board, at the May 11, 2020 meeting, discussed with Broadridge its methodology for assembling peer groups and discussed with the Advisor limitations in creating a relevant peer group for the Fund, including that (i) the Fund is unique in its composition, which makes assembling peers with similar strategies and asset mix difficult; and (ii) not all peer funds employ an advisor/sub-advisor management structure. The Board took these limitations into account in considering the peer data, and noted that the contractual advisory fee rate payable by the Fund, based on average managed assets, was below the median contractual advisory fee of the peer funds in the Expense Group. With respect to fees charged to other clients, the Board considered differences between the Fund and other clients that limited their comparability. In considering the advisory fee rate overall, the Board also considered the Advisor's statement that it seeks to meet investor needs through innovative and value-added investment solutions and the Advisor's demonstrated long-term commitment to the Fund and the other funds in the First Trust Fund Complex.

The Board considered performance information for the Fund. The Board noted the process it has established for monitoring the Fund's performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor and Sub-Advisor for the Fund. The Board determined that this process continues to be effective for reviewing the Fund's performance. The Board received and reviewed information comparing the Fund's performance for periods ended December 31, 2019 to the performance of the funds in the Performance Universe and to that of a blended benchmark index. In reviewing the Fund's performance as compared to the performance of the Performance Universe, the Board took into account the limitations described above with respect to creating a relevant peer group for the Fund. Based on the information provided on net asset value performance, the Board noted that the Fund outperformed the Performance Universe median for the one-, three- and five-year periods ended December 31, 2019. The Board also noted that the Fund outperformed the blended benchmark index for the one-year period ended December 31, 2019 but underperformed the blended benchmark index for the three- and five-year periods ended December 31, 2019. In addition, the Board considered information provided by the Advisor on the impact of leverage on the Fund's returns. The Board also received information on the Fund's annual distribution rate as of December 31, 2019 and the Fund's average trading discount for various periods and comparable information for a peer group.

On the basis of all the information provided on the fees, expenses and performance of the Fund and the ongoing oversight by the Board, the Board concluded that the advisory and sub-advisory fees continue to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor and the Sub-Advisor to the 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 Fund 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 Fund. The Board determined that due to the Fund's closed-end structure, the potential for realization of economies of scale as Fund assets grow was not a material factor to be considered. The Board considered the revenues and allocated costs (including the allocation methodology) of the Advisor in serving as investment advisor to the Fund for the twelve months ended December 31, 2019 and the estimated profitability level for the Fund calculated by the Advisor based on such data, as well as complex-wide and product-line profitability data, for the same period. The Board noted the inherent limitations in the profitability analysis and concluded that, based on the information provided, the Advisor's profitability level for the Fund was not unreasonable. In addition, the Board considered fall-out benefits described by the Advisor that may be realized from its relationship with the Fund. The Board considered the ownership interest of FTCP in the Sub-Advisor and potential fall-out benefits to the Advisor from such ownership interest. The Board noted that in addition to the advisory fees paid by the Fund, the Advisor is compensated for fund reporting services pursuant to a separate Fund Reporting Services Agreement. The Board concluded that the character and amount of potential fall-out benefits to the Advisor were not unreasonable.

The Board considered that the Sub-Advisor's investment services expenses are primarily fixed in nature, and that the Sub-Advisor has made recent investments in personnel and infrastructure and anticipates that its expenses will continue to rise due to additions to personnel and system upgrades. The Board did not review the profitability of the Sub-Advisor with respect to the Fund. The Board noted that the Advisor pays the Sub-Advisor from its advisory fee and its understanding that the Fund's sub-advisory fee rate was the product of an arm's length negotiation. The Board concluded that the profitability analysis for the Advisor was more relevant. The Board considered fall-out benefits that may be realized by the Sub-Advisor from its relationship with the Fund, including soft-dollar arrangements, and considered a summary of such arrangements. The Board also considered the potential fall-out benefits to the Sub-Advisor from the ownership interest of FTCP in the Sub-Advisor. The Board concluded that the character and amount of potential fall-out benefits to the Sub-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 the Fund. No single factor was determinative in the Board's analysis.

Changes Occurring During the Prior Fiscal Year

The following information is a summary of certain changes during the most recent fiscal year ended November 30, 2020. This information may not reflect all of the changes that have occurred since you purchased shares of the Fund.

During the Fund's most recent fiscal year, there were no material changes to the Fund's investment objective or policies that have not been approved by shareholders or in the principal risk factors associated with an investment in the Fund.

Investment Objective

The investment objective of the Fund is to seek a high level of total return with an emphasis on current distributions paid to shareholders. For purposes of the Fund's investment objective, total return includes capital appreciation of, and all distributions received from, securities in which the Fund invests, taking into account the varying tax characteristics of such securities.

Principal Investment Policies

The Fund seeks to provide its shareholders with an efficient vehicle to invest in a portfolio of cash-generating securities of publicly-traded master limited partnerships and limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, [YieldCos], pipeline companies, utilities, and other companies that derive at least 50% of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries (collectively, "Energy Infrastructure Companies").

The Fund:

Invests, under normal market conditions, at least 80% of its Managed Assets (as defined below) in securities of Energy Infrastructure Companies.
Invests in equity securities such as common stocks, preferred stocks, convertible securities, warrants, depository receipts and other equity interests in Energy Infrastructure Companies.
May directly invest up to 25% (or such higher amount as permitted by any future tax diversification rules) of its Managed Assets in equity securities of MLPs.

1. This limit does not apply to securities issued by MLP affiliates, such as I-Shares or general partner interests or other entities that may own interests of MLPs, unless such indirect interests are attributed to the Fund's investment limitation under federal tax law.
May invest up to 15% of its Managed Assets in unregistered or otherwise restricted securities of Energy Infrastructure Companies.
1. For the purpose of this limitation, "restricted securities" refers to securities that have not been registered under the 1933 Act or are held by control persons of the issuer and securities that are subject to contractual restrictions on their resale.
Will not invest more than 15% of its Managed Assets in any single issuer.
Will not invest directly in commodities.
May write (or sell) covered call options on up to 35% of its Managed assets to generate additional income.

Unless otherwise stated, all investment restrictions above apply at the time of purchase and the Fund will not be required to reduce a position due solely to market value fluctuations.

MLPs are limited partnerships whose shares (or units) are listed and traded on a U.S. securities exchange, just like common stock. To qualify as an MLP, a partnership must receive at least 90% of its income from qualifying sources such as natural resource activities. Natural resource activities include the exploration, development, mining, production, processing, refining, transportation and marketing of mineral or natural resources. MLPs generally have two classes of owners, the general partner and limited partners. The general partner, which is generally a major energy company, investment fund or the management of the MLP, typically controls the MLP through a 2% general partner equity interest in the MLP plus common units and subordinated units. Limited partners own the remainder of the partnership, through ownership of common units, and have a limited role in the partnership's operations and management.

I-Shares are similar in most respects to common units except that distributions payable on I-Shares are in the form of additional I-Shares rather than cash distributions. As a result, the Fund will consider its own distribution targets and cash holdings when making a determination as to whether to purchase I-Shares.

The covered call options the Fund may write (or sell) give the option holders the right, but not the obligation, to purchase a common stock at a specified price (the "strike price") on one or more future dates (each, an "exercise date"). The Fund writes call options only

Page 31

Investment Objective, Policies, Risks and Effects of Leverage (Continued)

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020 (Unaudited)

if they are "covered." In the case of a call option on a common stock or other security, the option is "covered" if the Fund owns the security underlying the call or has an absolute and immediate right to acquire that security without additional cash consideration (or, if additional cash consideration is required, cash or other assets determined to be liquid by the Sub-Advisor (in accordance with procedures established by the Board of Trustees) in such amount are segregated by the Fund's custodian) upon conversion or exchange of other securities held by the Fund.

The Fund may utilize hedging techniques such as interest rate swaps, caps, floors or collars or credit transactions and credit default swaps (or any combination thereof) to mitigate potential interest rate risk on a portion of its leverage instruments. Such interest rate and credit hedges are principally used to protect the Fund against higher costs on the Fund's leverage instruments resulting from increases in short-term interest rates. The Fund anticipates that the majority of the Fund's interest rate hedges will be interest rate swap contracts with financial institutions. The Fund may also enter into currency exchange transactions to hedge the Fund's exposure to foreign currency exchange rate risk to the extent the Fund invests in non-U.S. dollar denominated securities of non-U.S. issuers. The Fund's currency transactions will be limited to portfolio hedging involving portfolio positions. Portfolio hedging is the use of a currency forward contract with respect to a portfolio security position denominated or quoted in a particular currency. A currency forward contract is an agreement to purchase or sell a specified currency at a specified future date (or within a specified time period) and at a price set (or determined pursuant to parameters provided) at the time of the contract. Currency forward contracts are usually entered into with banks, foreign exchange dealers or broker-dealers, are not exchange-traded, and are usually for less than one year, but may be renewed.

The Fund may, to a lesser extent, purchase and sell other derivative investments such as exchange-listed and over-the-counter put and call options on securities, energy-related commodities, equity, fixed-income and interest rate indices and other financial instruments and purchase and sell financial futures contracts and options thereon. The Fund also may purchase derivative investments that combine features of these instruments.

"Managed Assets" means the average daily gross asset value of the Fund (which includes assets attributable to the Fund's preferred shares of beneficial interest ("Preferred Shares"), if any, and the principal amount of any borrowings), minus the sum of the Fund's accrued and unpaid dividends on any outstanding Preferred Shares and accrued liabilities (other than the principal amount of any borrowings of money incurred or of commercial paper or notes issued by the Fund). For purposes of determining Managed Assets, the liquidation preference of the Preferred Shares is not treated as a liability.

The Fund's investment policies may be changed by the Board of Trustees of the Fund without a shareholder vote, provided that shareholders receive at least 60 days' prior notice of any change.

Fundamental Investment Policies

The Fund, as a fundamental policy, may not:

Borrow money, except as permitted by the 1940 Act.
Issue senior securities, as defined in the 1940 Act, other than (i) preferred shares which immediately after issuance will have asset coverage of at least 200%, (ii) indebtedness which immediately after issuance will have asset coverage of at least 300%, or (iii) the borrowings permitted by investment restriction (1) set forth above.
Purchase or sell real estate, but this shall not prevent the Fund from investing in securities of companies that deal in real estate or are engaged in the real estate business, including real estate investment trusts, and securities secured by real estate or interests therein and the Fund may hold and sell real estate or mortgages on real estate acquired through default, liquidation, or other distributions of an interest in real estate as a result of the Fund's ownership of such securities.
Act as underwriter of another issuer's securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933 in connection with the purchase and sale of portfolio securities.
Make loans of funds or other assets, other than by entering into repurchase agreements, lending portfolio securities and through the purchase of securities in accordance with its investment objective, policies and limitations.
Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling options, futures contracts, derivative instruments or from investing in securities or other instruments backed by physical commodities).
Concentrate (invest 25% or more of total assets) the Fund's investments in any particular industry, except that the Fund will concentrate its assets in any of the group of industries constituting the energy infrastructure sector.

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020 (Unaudited)

Except as noted above, the foregoing fundamental investment policies, together with the investment objective of the Fund, cannot be changed without approval by holders of a majority of the outstanding voting securities of the Fund, as defined in the 1940 Act, which includes common shares of beneficial interest of the Fund ("Common Shares") and Preferred Shares, if any, voting together as a single class, and of the holders of the outstanding Preferred Shares voting as a single class. Under the 1940 Act, a "majority of the outstanding voting securities" means the vote of: (i) 67% or more of the Fund's shares present at a meeting, if the holders of more than 50% of the Fund's shares are present or represented by proxy, or (ii) more than 50% of the Fund's shares, whichever is less.

Principal Risks

The Fund is a closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objective. The following discussion summarizes the principal risks associated with investing in the Fund, which includes the risk that you could lose some or all of your investment in the Fund. The Fund is subject to the informational requirements of the Securities Exchange Act of 1934 and the Investment Company Act of 1940 and, in accordance therewith, files reports, proxy statements and other information that is available for review.

Covered Call Options Risk. As the writer (seller) of a call option, the Fund forgoes, during the life of the option, the opportunity to profit from increases in the market value of the portfolio security covering the option above the sum of the premium and the strike price of the call option but retains the risk of loss should the price of the underlying security decline. The value of call options written by the Fund, which are priced daily, are determined by trading activity in the broad options market and will be affected by, among other factors, changes in the value of the underlying security in relation to the strike price, changes in dividend rates of the underlying security, changes in interest rates, changes in actual or perceived volatility of the stock market and the underlying security, and the time remaining until the expiration date. The value of call options written by the Fund may be adversely affected if the market for the option is reduced or becomes illiquid. There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position.

Cyber Security Risk. The Fund is 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 the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund's digital information systems through "hacking" or malicious software coding, but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the 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 the Fund to many of the same risks associated with direct cyber security breaches. The Fund has established risk management systems designed to reduce the risks associated with cyber security. However, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third party service providers.

Energy Infrastructure Companies Risk. The Fund primarily invests in MLPs, MLP affiliates, YieldCos, pipeline companies, utilities, and other infrastructure-related companies that derive at least 50% of their revenues from operating, or providing services in support of, infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries ("Energy Infrastructure Companies"). Energy Infrastructure Companies may be directly affected by energy commodity prices, especially those Energy Infrastructure Companies which own the underlying energy commodity. A decrease in the production or availability of natural gas, natural gas liquids, crude oil, coal or other energy commodities or a decrease in the volume of such commodities available for transportation, processing, storage or distribution may adversely impact the financial performance of Energy Infrastructure Companies. Energy Infrastructure Companies are subject to significant federal, state and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and the prices they may charge for products and services. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the financial performance of Energy Infrastructure Companies. Natural disasters, such as hurricanes in the Gulf of Mexico, also may impact Energy Infrastructure Companies.

Certain Energy Infrastructure Companies are subject to the imposition of rate caps, increased competition due to deregulation, counterparties to contracts defaulting or going bankrupt, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects, the limitations on operations and increased costs and delays attributable to environmental considerations, and the capital market's ability to absorb utility debt. In addition, taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation may cause difficulties for these companies.

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020 (Unaudited)

Equity Securities Risk. The value of the Fund's shares will fluctuate with changes in the value of the equity securities in which the Fund invests. Prices of equity securities 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.

Interest Rate Swaps Risk. If short-term interest rates are lower than the Fund's fixed rate of payment on an interest rate swap, the swap will reduce common share net earnings. In addition, a default by the counterparty to a swap transaction could also negatively impact the performance of the common shares.

Investment Concentration Risks. The Fund's investments are concentrated in Energy Infrastructure Companies (including investments in MLPs), which may present more risk than if the Fund were broadly diversified over multiple sectors of the economy. A downturn in one or more industries within the energy infrastructure sector, material declines in commodity prices, adverse political, legislative or regulatory developments or other events could have a larger impact on the Fund than on an investment company that does not concentrate in the energy infrastructure sector. Certain risks inherent in investing in the business of the types of securities that the Fund may invest (such as interests in MLPs) include: commodity pricing risk, commodity supply and demand risk, lack of diversification of and reliance on customers and suppliers risk including risk of counterparty default, commodity depletion and exploration risk, energy infrastructure sector and energy utility industry regulatory risk, including risks associated with the prices and methodology of determining prices that energy companies may charge for their products and services, interest rate risk, risk of lack of acquisition or reinvestment opportunities, risk of lacking of funding, dependency on MLP affiliate risk, weather risk, catastrophe risk, terrorism and MLP market disruption risk, obsolescence risk and technology risk.

Companies that own interstate pipelines are subject to regulation by the Federal Energy Regulatory Commission (FERC) with respect to the tariff rates that they may charge to their customers. In March 2018, FERC changed its tax allowance policy to no longer permit such companies to include in their cost of service an income tax allowance to the extent that their owners have an actual or potential tax liability on the income generated by them. This has had a negative impact on the performance of some energy companies affected by this decision.

Other factors which may reduce the amount of cash an MLP or other Energy Infrastructure Company has available to pay its debt and equity holders include increased operating costs, maintenance capital expenditures, acquisition costs, expansion or construction costs and borrowing costs (including increased borrowing costs as a result of additional collateral requirements as a result of ratings downgrades by credit agencies).

Leverage Risk. The use of leverage by the Fund can magnify the effect of any losses. If the income and gains from the securities and investments purchased with leverage proceeds do not cover the cost of leverage, the return to the common shares will be less than if leverage had not been used. Leverage involves risks and special considerations for common shareholders including: the likelihood of greater volatility of net asset value and market price of the common shares than a comparable portfolio without leverage; the risk that fluctuations in interest rates on borrowings will reduce the return to the common shareholders or will result in fluctuations in the dividends paid on the common shares; in a declining market, the use of leverage is likely to cause a greater decline in the net asset value of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares; and when the Fund uses certain types of leverage, the investment advisory fee payable to the Advisor and by the Advisor to the Sub-Advisor will be higher than if the Fund did not use leverage.

Liquidity Risk. Certain securities in which the Fund may invest may trade less frequently, particularly those of issuers with smaller capitalizations. Securities with limited trading volumes may display volatile or erratic price movements. The Fund may have difficulty selling these investments in a timely manner, be forced to sell them for less than it otherwise would have been able to realize, or both.

Management Risk and Reliance on Key Personnel. The implementation of the Fund's investment strategy depends upon the continued contributions of certain key employees of the Advisor and Sub-Advisor, some of whom have unique talents and experience and would be difficult to replace. The loss or interruption of the services of a key member of the portfolio management team could have a negative impact on the Fund.

Market Discount from Net Asset Value. Shares of closed-end investment companies such as the Fund frequently trade at a discount from their net asset value. The Fund cannot predict whether its common shares will trade at, below or above net asset value.

Market Risk. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such

events may affect certain geographic regions, countries, sectors and industries more significantly than others. The outbreak of the respiratory disease designated as COVID-19 in December 2019 has caused significant volatility and declines in global financial markets, which have caused losses for investors. The COVID-19 pandemic may last for an extended period of time and will continue to impact the economy for the foreseeable future.

As a result of the COVID-19 pandemic and the subsequent economic shutdowns, demand for commodities fell sharply and commodity prices experienced significant disruptions. Russia and Saudi Arabia initially failed to come to an agreement on the reduction of oil production, and the resulting glut in supply and price war cratered oil prices to historic lows. OPEC and Russia eventually agreed to and extended several oil production cuts, but oil prices remain depressed. The COVID-19 pandemic continues to impact global economies and financial markets, including the energy sector, which in turn continues to impact the Fund and its investments.

MLP Risk. Investments in securities of MLPs involve certain risks different from or in addition to the risks of investing in common stocks. MLP common units can be affected by macro-economic factors and other factors unique to the partnership or company and the industry or industries in which the MLP operates. Certain MLP securities may trade in relatively low volumes due to their smaller capitalizations or other factors, which may cause them to have a high degree of price volatility and illiquidity. The structures of MLPs create certain risks, including, for example, risks related to the limited ability of investors to control a MLP and to vote on matters affecting the MLP, risks related to potential conflicts of interest between an MLP and the MLP's general partner, the risk that an MLP will generate insufficient cash flow to meet its current operating requirements, the risk that an MLP will issue additional securities or engage in other transactions that will have the effect of diluting the interests of existing investors, and risks related to the general partner's right to require unit-holders to sell their common units at an undesirable time or price.

Non-DiversificationRisk. As a "non-diversified" fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund's shares may be more volatile than the values of shares of more diversified funds.

Non-U.S.Securities and Currency Risk. Investing in non-U.S. securities involves certain risks not involved in domestic investments, including, but not limited to: fluctuations in currency exchange rates; future foreign economic, financial, political and social developments; different legal systems; the possible imposition of exchange controls or other foreign governmental laws or restrictions; lower trading volume; withholding taxes; greater price volatility and illiquidity; different trading and settlement practices; less governmental supervision; high and volatile rates of inflation; fluctuating interest rates; less publicly available information; and different accounting, auditing and financial recordkeeping standards and requirements. Because the Fund may invest in securities denominated or quoted in non-U.S. currencies, changes in the non-U.S. currency/United States dollar exchange rate may affect the value of the Fund's securities and the unrealized appreciation or depreciation of investments.

Potential Conflicts of Interest Risk. First Trust, EIP and the portfolio managers have interests which may conflict with the interests of the Fund. In particular, First Trust and EIP currently manage and may in the future manage and/or advise other investment funds or accounts with the same or substantially similar investment objective and strategies as the Fund. In addition, while the Fund is using leverage, the amount of the fees paid to First Trust (and by First Trust to EIP) for investment advisory and management services are higher than if the Fund did not use leverage because the fees paid are calculated based on managed assets. Therefore, First Trust and EIP have a financial incentive to leverage the Fund.

Qualified Dividend Income Tax Risk. There can be no assurance as to what portion of the distributions paid to the Fund's common shareholders will consist of tax-advantaged qualified dividend income. Certain distributions designated by the Fund as derived from qualified dividend income will be taxed in the hands of non-corporate common shareholders at the rates applicable to long-term capital gains, provided certain holding period and other requirements are satisfied by both the Fund and the common shareholders. Additional requirements apply in determining whether distributions by foreign issuers should be regarded as qualified dividend income. Certain investment strategies of the Fund will limit the Fund's ability to meet these requirements and consequently will limit the amount of qualified dividend income received and distributed by the Fund. A change in the favorable provisions of the federal tax laws with respect to qualified dividends may result in a widespread reduction in announced dividends and may adversely impact the valuation of the shares of dividend-paying companies.

Recent Market and Economic Developments. The number of energy-related MLPs has declined since 2014. The industry is witnessing the consolidation or simplification of corporate structures where the MLP sleeve of capital is being eliminated. As a result of the foregoing, the Fund's MLP investments could become less diverse and the Fund may increase its non-MLP investments consistent with its investment objective and policies.

Tax Risk. A change in current tax law, a change in the business of a given MLP, or a change in the types of income earned by a given MLP could result in an MLP being treated as a corporation for United States federal income tax purposes, which would result in such

Page 35

Investment Objective, Policies, Risks and Effects of Leverage (Continued)

First Trust Energy Infrastructure Fund (FIF)

November 30, 2020 (Unaudited)

MLP being required to pay United States federal income tax on its taxable income. Recent events have caused some MLPs to be reclassified or restructured as corporations. The classification of an MLP as a corporation for United States federal income tax purposes has the effect of reducing the amount of cash available for distribution by the MLP and causing any such distributions received by the Fund to be taxed as dividend income to the extent of the MLP's current or accumulated earnings and profits.

A reduction in the percentage of the income offset by tax deductions or an increase in sales of the Fund's MLP holdings that result in capital gains will reduce that portion of the Fund's distribution from an MLP treated as a return of capital and increase that portion treated as income, and may result in lower after-tax distributions to the Fund's common shareholders. On the other hand, to the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund's adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in the amount of income or gain or decrease in the amount of loss that will be recognized by the Fund for tax purposes upon the sale of any such interests.

Changes in tax laws or regulations, or interpretations thereof in the future, could adversely affect the Fund or the MLPs, MLP-related entities and other energy sector and energy utility companies in which the Fund invests.

Utilities Risk. Utility companies include companies producing or providing gas, electricity or water. These companies are subject to the risk of the imposition of rate caps, increased competition due to deregulation, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects, the limitations on operations and increased costs and delays attributable to environmental considerations and the capital market's ability to absorb utility debt. In addition, taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation may negatively affect utility companies.

Valuation Risk. Market prices generally will not be available for certain investments in MLPs, and the value of such investments will ordinarily be determined based on fair valuations determined pursuant to procedures adopted by the Board of Trustees. The value of these securities typically requires more reliance on the judgment of the Sub-Advisor than that required for securities for which there is an active trading market. In addition, the Fund relies on information provided by certain MLPs, which is usually not timely, to calculate taxable income allocable to the MLP units held in the Fund's portfolio and to determine the tax character of distributions to common shareholders. From time to time the Fund will modify its estimates and/or assumptions as new information becomes available. To the extent the Fund modifies its estimates and/or assumptions, the net asset value of the Fund would likely fluctuate.

Effects of Leverage

The aggregate principal amount of borrowings under the credit agreement (the "Credit Agreement") with The Bank of Nova Scotia represented approximately 20.35% of Managed Assets as of November 30, 2020. Asset coverage with respect to the Borrowings under the Credit Agreement was 491.39% and the Fund had $10,700,000 of unutilized funds available for borrowing under the Credit Agreement as of that date. As of November 30, 2020, the maximum commitment amount was $66,000,000. As of November 30, 2020, the approximate average annual interest and fee rate was 1.08%.

Assuming that the Fund's leverage costs remain as described above (at an assumed average annual cost of 1.08%), the annual return that the Fund's portfolio must experience (net of expenses) in order to cover its leverage costs would be 0.23%.

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on Common Share total return, assuming investment portfolio total returns (comprised of income and changes in the value of securities held in the Fund's portfolio) of (10)%, (5)%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund.

The table further assumes leverage representing 21.36% of the Fund's Managed Assets, net of expenses, and an annual leverage interest and fee rate of 1.08%.

Assumed Portfolio Total Return (Net of Expenses) . . . . . . . . . . . . . . . . . . . . . .	-10%	-5%	0%	5%	10%
Common Share Total Return . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .	-13.01%	-6.65%	-0.29%	6.06%	12.42%

Common Share total return is composed of two elements: the Common Share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends or interest on its leverage) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table above assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the distributions it receives on its investments is entirely offset by losses in the value of those securities.
