LETTER TO STOCKHOLDERS

March 18, 2026

Dear Fellow Stockholders,

We are pleased to provide an update on KYN's performance, portfolio positioning, and our perspective on the financial markets and recent geopolitical events. It has been an exceptional start to the year - KYN's Net Asset Return was 17.5% for the first quarter of fiscal 2026.(1)

Before we delve into our quarterly update, it is worth reiterating several comments made in our 2025 annual letter: first, we remain confident in KYN's potential to generate low-to-mid teens annual returns over the next five years, as the fundamental drivers of this return expectation continue to improve.(2) Second, an allocation to energy infrastructure provides investors exposure to "must run" assets that play an essential role in the global economy - a point that has been emphasized by the conflict unfolding in the Middle East. Third, energy infrastructure provides investors a potential hedge against higher-than-expected levels of inflation, a topic that is receiving quite a bit of attention these days.

The macro backdrop is volatile, and the first four months of fiscal 2026 have been heavily influenced by rapidly shifting market narratives. We began the year anticipating periods of higher-than-normal uncertainty, and unfortunately, we were spot on regarding this forecast. We do not expect this to change any time soon, but we believe KYN is well prepared for this type of market environment. We remain invested in our highest conviction ideas and continue to manage risk deliberately with more moderate leverage levels and a downside cushion at the high end of our target range.(3)

KYN's fiscal Q1 overview:

• Net Asset Return for the quarter was 17.5%;(1),(4)

• Net Asset Return for the last twelve months was 17.6%;(1),(5) and

• KYN was the best performing midstream fund over the last two years, with a Net Asset Return of 75.4%.(1),(6),(7)

Portfolio Positioning

As of February 28, 2026, the portfolio was invested 95% in midstream equities, 4% in power infrastructure equities, and 1% in credit and other investments. The substantial majority of KYN's portfolio (98%) is invested in listed securities (i.e., public companies). Our approach remains centered on equity investments in large-cap midstream companies, which are businesses we believe can sustain cash flows across a range of market environments. Further, these companies are particularly well positioned for a volatile geopolitical backdrop.

Macro Backdrop

Fiscal Q1 unfolded against an unusually volatile and unsettled macro backdrop. Performance for the major equity indices was modest during the quarter (the S&P 500 was up 0.7% and the NASDAQ was down 2.9%),(8) but those headline returns mask a significant dispersion in performance of the various sectors that comprise the U.S. equity markets. The performance gap between the top 50 and bottom 50 constituents of the S&P 500 reached approximately 65% in early 2026, the widest spread in more than two decades. There has been a shift in market leadership, and stock selection is particularly important in the current environment.

LETTER TO STOCKHOLDERS

Having left interest rates unchanged at its last two meetings, the Federal Reserve appears to be in "wait-and-see mode". This is understandable given mixed economic signals coupled with uncertainty related to the conflict in Iran. Interest rates were rangebound for most of the first quarter but moved higher in March on concerns of worsening inflation trends.

Artificial intelligence, or "A.I.," continues to garner a significant amount of attention in the financial markets, and there were some noticeable shifts in the "A.I trade" narrative over the last few months. First, given the large amounts of capital being invested, investors have become more discerning with respect to their A.I. exposure. In particular, they are very focused on the returns companies are expected to generate from their A.I.-related investments. Second, investors are considering the disruptive impact A.I. may have on certain industries, such as the potential for impairments to more asset-light business models (e.g., software/SaaS, digital media, professional services, etc.). In response to these concerns, capital rotated away from these companies and into "HALO" businesses (heavy assets, low obsolescence), which are considered to be less prone to A.I.-related disruptions. This rotation is well illustrated by the S&P 500's best performing subsectors during fiscal Q1: energy, materials, and industrials.

Energy Infrastructure Update

Energy infrastructure equities performed very well during the quarter, with the AMNA up 17.9% and the XLU up 6.1%. With hard assets and durable cash flows, the sector is well positioned to benefit from the shift in investor preferences towards HALO businesses. In addition, midstream companies continue to execute well - Q4 '25 financial results were positive for many names, with solid forward guidance and improved investor confidence in growth prospects. The result was a combination of multiple expansion and upward earnings revisions that drove strong performance in midstream equities. Within KYN's portfolio, there are two midstream holdings to highlight this quarter: Enterprise Products (EPD) and Williams Companies (WMB).

EPD's Q4 '25 financial results were excellent (one of its best quarters in the last five years), with a positive read on both growth trajectory and return of capital potential. Given the company's strong balance sheet, it can direct incremental free cash flow to equity holders as capital spending tapers in 2026 and 2027. At the same time, its business is expected to generate mid-single digit cash flow growth over the next two years. EPD is one of KYN's largest holdings and is a good example of the attributes we seek for the Company's exposure to liquids-focused midstream companies.

WMB is another large position in KYN's portfolio. The company held its highly anticipated analyst day in February, in which it projected a 35% increase in domestic natural gas demand over the next decade, driven by growing liquified natural gas (LNG) exports and load growth from industrial reshoring and data center development. WMB meaningfully increased its estimate for annual EBITDA growth for the next five years (to annual growth of at least 10%) - this update was well received by investors. We are excited about WMB's ability to deliver industry-leading growth rates, and the company remains one of our preferred ways to capitalize on the structural demand growth in the natural gas market.

LETTER TO STOCKHOLDERS

Power infrastructure also delivered solid Q4 '25 financial results, supported by continued acceleration in load growth expectations tied to data center demand and industrial reshoring. This load growth is increasingly being codified through expanding data center backlogs and new electric service agreements (ESAs), which support upward revisions to capital plans and earnings outlooks for regulated utilities. At the same time, stock price performance was mixed across utilities and independent power producers (IPPs) as regulatory frameworks, quality/visibility of capital plans, and affordability considerations continue to influence investor sentiment.

Geopolitical Backdrop

Between U.S. actions taken in Venezuela and the ongoing conflict in Iran, it has been a highly eventful three months for geopolitics. While much global uncertainty persists, these events highlight the important role that the U.S. plays as a global energy supplier, and the critical role domestic energy infrastructure assets play in ensuring U.S. production is exported to countries across the globe.

Venezuela became a focal point in early January after the U.S. captured Nicolás Maduro, the Venezuelan president, in a targeted operation. The U.S. then signaled a framework to re-engage Venezuela economically by encouraging private investment in Venezuela's energy sector. The U.S. administration's goal is to materially increase Venezuela's production to levels last seen 10 to 20 years ago. We have a cautious view on the likelihood of this occurring in the near-to-medium-term. In our opinion, it will require a considerable amount of capital, a more stable operating environment, and certainty regarding the legal framework governing ownership of these reserves. Nonetheless, a redirection of Venezuela's crude oil exports to the U.S. Gulf Coast (which is currently taking place) is positive for domestic refiners as well as the midstream sector. Many liquids-focused midstream companies are well positioned to facilitate the import of incremental volumes.

The more material global geopolitical development occurred at the end of fiscal Q1, when the U.S. and Israel initiated a coordinated attack on Iran. The conflict has escalated over the last three weeks, with energy and other infrastructure assets across the Middle East region being targeted by Iran in response to these hostilities. As of the date of this letter, the attacks continue and there have been no clear signs of a path to de-escalation.

The impact of the conflict on global energy flows has been profound. Iran has taken steps to shut down transit through the Strait of Hormuz, a vital conduit for global crude, refined products, and LNG trade. While the U.S. has been assertive in announcing plans to restabilize trade flows, it is unclear how quickly (or effectively) this can be effectuated. For context, approximately 20% of global crude supply and LNG volumes flow through the Strait. Any prolonged impairment to shipments from the Middle East will have meaningful consequences for global energy balances and the global economy.

In addition to disrupted trade flows, energy infrastructure assets in the region are directly impacted. Critical assets are halting operations, including both Ras Laffan in Qatar (the world's largest LNG export facility) and Ras Tanura in Saudi Arabia (the country's largest refinery). Operations have also been suspended at export terminals in Kuwait and the UAE. These constraints have forced meaningful curtailments across key regional producers, and it will take time to restore production capacity once the conflict is resolved.

Governments have moved quickly to attempt to mitigate the effect on global crude prices, with the International Energy Agency (IEA) announcing a coordinated strategic petroleum reserve (SPR) release of 400 million barrels, the largest coordinated release in history. There have been a host of other initiatives

LETTER TO STOCKHOLDERS

announced in response to these events as the U.S. and other countries attempt to dampen the impact of this supply disruption. The key question now is how long the conflict will last, as the proposed actions are not enough to insulate the market from an extended disruption.

Reaction in Commodity Markets

The impact of these developments on commodity markets has been significant. As shown in the table below, crude prices have increased by ~$30 per barrel (~43%) since the conflict began. What is particularly noteworthy is the impact this conflict is having not only on current prices, but on futures markets as well. Domestic crude prices (as measured by WTI) for the next 12 months are up 25% thus far in March, and prices for 2027 are up 13%. This is in response to the potential for longer-lasting disruptions to supply as well as a higher risk premium in commodity prices. The conflict is having an even more pronounced impact on refined products and refining crack spreads, with material disruptions being reported in European and Asian economies due to fuel shortages.

Global natural gas prices have increased more than oil prices thus far in March, as traders repriced the probability of tighter seaborne supply and higher delivered costs in import-dependent regions. Global gas prices had largely traded in an $8 to $12 per MMBtu range over the past twelve months, but quickly traded much higher once the hostilities commenced. Prompt TTF (Europe) and JKM (Asia) prices are up over 50% thus far in March, with a similar move in forward market prices next winter.

What is the Impact on KYN's Portfolio Investments?

It is important to emphasize that the domestic energy infrastructure businesses in which KYN invests generally have limited direct exposure to commodity prices, as cash flows are primarily supported by long-term, fixed-fee contracts and are more dependent on volume throughput. That said, the sector does have indirect exposure. Commodity prices can influence sentiment and near-term trading dynamics, and prolonged price strength (or weakness) can drive changes in producer behavior - most notably in drilling and completion activity that would impact domestic production volumes. Further, there are some midstream companies that have direct exposure to commodity prices and/or basis differentials. While this exposure is limited, these companies do benefit financially from higher commodity prices.

KAYNE ANDERSON ENERGY INFRASTRUCTURE FUND, INC.
LETTER TO STOCKHOLDERS

The Iranian conflict (and associated increases in commodity prices) is not expected to materially change near-term cash flow estimates for most of KYN's holdings, but it does create positive tailwinds. Financial guidance was issued in late 2025 or early 2026, when prices were much lower, and many companies were more cautious regarding activity levels during 2026. There is a positive bias on both items given recent events, which could set up certain names to beat their more muted outlooks. Further, we expect that the elevated strategic importance of U.S.-based energy infrastructure assets will create a positive backdrop for contract extensions and rate renegotiations, as well as incremental growth projects to facilitate exports. We expect this to be a positive tailwind for the midstream sector over the next few years.

Why Invest in KYN?

We believe that KYN - with its flexible investment mandate, permanent capital base, and expertise in providing capital solutions to both public and private companies - is an attractive means to gain exposure to the North American energy infrastructure sector. The Company provides this exposure in an easy-to-own structure with daily liquidity, an attractive monthly distribution, and the tax simplicity of a single Form 1099. We appreciate the trust you have placed in us and are grateful for your support. We are confident the stage is set for a successful 2026 and beyond. We value the opportunity to connect with our fellow stockholders and encourage you to reach out with any questions, comments or feedback. We look forward to hearing from you.

Sincerely,

James C. Baker, Jr.

Chairman of the Board

President and Chief Executive Officer

MANAGEMENT DISCUSSION
(UNAUDITED)

Company Overview

Kayne Anderson Energy Infrastructure Fund, Inc. (the "Company" or "KYN") is a non-diversified, closed-end fund that commenced operations in September 2004. Our investment objective is to provide a high after-tax total return with an emphasis on making cash distributions to stockholders. We intend to achieve our investment objective by investing at least 80% of our total assets in the securities of Energy Infrastructure Companies. Please refer to the Glossary of Key Terms for the meaning of capitalized terms not otherwise defined herein.

As of February 28, 2026, we had total assets of $3.7 billion, net assets applicable to our common stockholders of $2.7 billion (net asset value of $15.90 per share) and 169.1 million shares of common stock outstanding.

Our Top Ten Portfolio Investments

Listed below are our top ten portfolio investments by issuer as of February 28, 2026.

Results of Operations - For the Three Months Ended February 28, 2026

Investment Income. Investment income totaled $25.6 million for the quarter. We received $43.3 million of dividends and distributions. We estimated that $17.9 million of the dividends and distributions received were return of capital distributions and/or distributions in excess of cost basis. Interest income was $0.2 million.

Operating Expenses. Operating expenses totaled $19.8 million, including $11.2 million of investment management fees (net of fee waivers), $6.0 million of interest expense, $1.6 million of preferred stock distributions and $1.0 million of other operating expenses.

Net Investment Income. Our net investment income was $5.2 million and included a deferred tax expense of $0.6 million.

KAYNE ANDERSON ENERGY INFRASTRUCTURE FUND, INC.
MANAGEMENT DISCUSSION
(UNAUDITED)

Net Realized Gains. We had net realized gains of $38.5 million, consisting of realized gains from long term investments of $48.7 million and a deferred tax expense of $10.2 million.

Net Change in Unrealized Gains. We had a net increase in our unrealized gains of $354.9 million. The net change consisted of a $449.2 million increase in unrealized gains on investments and a deferred tax expense of $94.3 million.

Net Increase in Net Assets Resulting from Operations. As a result of the above, we had a net increase in net assets resulting from operations of $398.6 million.

Distributions to Common Stockholders

The Company pays distributions on a monthly basis. During the three months ended February 28, 2026, the Company paid a monthly distribution of $0.08 per common share on December 31, 2025, and $0.085 per common share on January 30, 2026 and on February 27, 2026. Payment of future distributions is subject to the approval of the Company's Board of Directors, as well as meeting the covenants on the Company's debt agreements and the terms of its preferred stock.

The Board of Directors considers several items in setting our distributions to common stockholders including net distributable income (as defined below), realized and unrealized gains and expected returns for portfolio investments.

Net distributable income ("NDI") is the amount of income received by us from our portfolio investments less operating expenses, subject to certain adjustments as described below. NDI is not a financial measure under the accounting principles generally accepted in the United States of America ("GAAP"). Refer to the Reconciliation of NDI to GAAP section for a reconciliation of this measure to our results reported under GAAP.

For the purposes of calculating NDI, income from portfolio investments includes (a) cash dividends and distributions, (b) paid-in-kind dividends received (i.e., stock dividends), (c) interest income from debt securities and (d) net premiums received from the sale of covered calls.

For the purposes of calculating NDI, operating expenses include (a) investment management fees paid to our investment adviser, (b) other expenses (mostly comprised of fees paid to other service providers), (c) interest expense and preferred stock distributions and (d) current and deferred income tax expense/benefit on net investment income/loss.

Net Distributable Income (NDI)
(amounts in millions, except for per share amounts)

Reconciliation of NDI to GAAP

The difference between distributions and other income from investments in the NDI calculation and total investment income as reported in our Statement of Operations is reconciled as follows:

• A significant portion of the cash distributions received from our investments is characterized as return of capital. For GAAP purposes, return of capital distributions are excluded from investment income, whereas the NDI calculation includes the return of capital portion of such distributions.

• GAAP recognizes distributions received from our investments that exceed the cost basis of our securities to be realized gains and are therefore excluded from investment income, whereas the NDI calculation includes these distributions.

• We may sell covered call option contracts to generate income or to reduce our ownership of certain securities that we hold. In some cases, we are able to repurchase these call option contracts at a price less than the call premium that we received, thereby generating a profit. The premium we receive from selling call options, less (i) the premium that we pay to repurchase such call option contracts and (ii) the amount by which the market price of an underlying security is above the strike price at the time a new call option is written (if any), is included in NDI. For GAAP purposes, premiums received from call option contracts sold are not included in investment income. See Note 2 - Significant Accounting Policies for the GAAP treatment of option contracts.

Liquidity and Capital Resources

As of February 28, 2026, we had total leverage outstanding of $599 million, which was comprised of $45 million of borrowings outstanding under our unsecured revolving credit facility (the "Credit Facility"), $400 million of senior unsecured notes ("Notes") and $154 million of mandatory redeemable preferred stock ("MRP Shares").

As of February 28, 2026, total leverage represented approximately 16% of total assets. Under normal market conditions, our policy is to utilize leverage in an amount that represents approximately 20% to 25% of total assets. Currently, we intend to operate with leverage below the lower end of this range, maintaining total leverage in a range of approximately 17.5% to 20% of total assets. Our current leverage level reflects a deliberate positioning below this range in light of market conditions.

As of February 28, 2026, we had $1 million of short term investments in money market funds and $1 million of cash. As of April 17, 2026, we had $98 million of borrowings outstanding under our Credit Facility and we had $2 million of short term investments in money market funds.

On February 19, 2026, we renewed our Credit Facility. The renewed Credit Facility maintains the Company's $175 million commitment and extends the maturity date to February 18, 2027, replacing the prior facility, which was scheduled to mature on February 19, 2026. Borrowings under the renewed facility bear interest at SOFR plus a spread ranging from 1.30% to 2.15%, depending on the Company's asset coverage ratios. Based on current asset coverage, the applicable spread is 1.30%. We pay a fee of 0.20% per annum on any unused amounts of the Credit Facility.

As of February 28, 2026, we had $400 million of Notes outstanding that mature between 2028 and 2036 and we had $154 million of MRP Shares outstanding that are subject to mandatory redemption between 2026 and 2032. We expect to have sufficient capacity under our Credit Facility to refinance the upcoming 2026 MRP Shares maturity ($12 million), although we may elect to refinance all or a portion of such maturity through the issuance of new MRP Shares or other financing alternatives.

As of February 28, 2026, our asset coverage ratios under the Investment Company Act of 1940, as amended ("1940 Act"), were 739% for debt and 549% for total leverage (debt plus preferred stock). We target asset coverage ratios that give us the ability to withstand declines in the market value of the securities we hold before breaching the financial covenants in our leverage (we refer to this as our "downside cushion"). At this time, we target asset coverage ratios that provide approximately 55% to 60% of downside cushion relative to our financial covenants. Our leverage targets are dependent on market conditions as well as certain other factors and may vary from time to time.

As of February 28, 2026, our total leverage consisted of 92% of fixed rate obligations and 8% of floating rate obligations. At such date, the weighted average interest/dividend rate on our total leverage was 4.82%.

Represents the value of total assets less all liabilities not represented by Notes (principal value), or any other senior securities representing indebtedness and MRP Shares (liquidation value) divided by the aggregate amount of Notes and any other senior securities representing indebtedness. Under the 1940 Act, the Company may not declare or make any distribution on its common stock nor can it incur additional indebtedness if, at the time of such declaration or incurrence, its asset coverage with respect to senior securities representing indebtedness would be less than 300%.

(12) Calculated pursuant to section 18(a)(2)(A) of the 1940 Act. Represents the value of total assets less all liabilities not represented by Notes (principal value), any other senior securities representing indebtedness and MRP Shares (liquidation value) divided by the aggregate amount of Notes, any other senior securities representing indebtedness and MRP Shares. Under the 1940 Act, the Company may not declare or make any distribution on its common stock nor can it issue additional preferred stock if at the time of such declaration or issuance, its asset coverage with respect to all senior securities would be less than 200%. In addition to the limitations under the 1940 Act, the Company, under the terms of its MRP Shares, would not be able to declare or pay any distributions on its common stock if such declaration would cause its asset coverage with respect to all senior securities to be less than 225%.

1. Organization

Kayne Anderson Energy Infrastructure Fund, Inc. (the "Company" or "KYN") was organized as a Maryland corporation on June 4, 2004, and is a non-diversified, closed-end management investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"). The Company's investment objective is to provide a high after-tax total return with an emphasis on making cash distributions to stockholders. The Company intends to achieve this objective by investing at least 80% of its total assets in the securities of Energy Infrastructure Companies. The Company commenced operations on September 28, 2004. The Company's shares of common stock are listed on the New York Stock Exchange, Inc. ("NYSE") under the symbol "KYN." For more information about the Company's investment objective, policies and principal risks, see Investment Objective, Policies and Risks in the Company's most recently filed annual report.

2. Significant Accounting Policies

The following is a summary of the significant accounting policies that the Company uses to prepare its financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The Company is an investment company and follows accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 946 - "Financial Services - Investment Companies."

A. Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expenses during the period. Actual results could differ materially from those estimates.

B. Cash and Cash Equivalents - Cash and cash equivalents include short-term, liquid investments with an original maturity of three months or less and include money market fund accounts.

C. Calculation of Net Asset Value - The Company determines its net asset value on a daily basis and reports its net asset value on its website. Net asset value is computed by dividing the value of the Company's assets (including accrued interest and distributions and current and deferred income tax assets), less all of its liabilities (including accrued expenses, distributions payable, current and deferred accrued income taxes, and any borrowings) and the liquidation value of any outstanding preferred stock, by the total number of common shares outstanding.

D. Investment Valuation - Pursuant to Rule 2a-5, the Company's Board of Directors (the "Board") has designated KA Fund Advisors, LLC ("KAFA"), the Company's investment adviser, as the "Valuation Designee" to perform fair value determinations of the Company's portfolio holdings, subject to oversight by and periodic reporting to the Board. The Valuation Designee determines the fair value of the Company's portfolio holdings in accordance with the Company's valuation program, as adopted by the Board.

Readily marketable portfolio securities listed on any exchange (including a foreign exchange) other than The Nasdaq Stock Market LLC ("NASDAQ") are valued, except as indicated below, at the last sale price on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the most recent bid and ask prices on such day. Securities admitted to trade on the NASDAQ are valued at the NASDAQ official closing price. Portfolio securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

(UNAUDITED)

The value of foreign securities traded outside of the Americas may be adjusted to reflect events occurring after a foreign exchange closes that may affect the value of the foreign security. In such cases, these foreign securities are valued by an independent pricing service and are categorized as Level 2 securities for purposes of the fair value hierarchy. See Note 3 - Fair Value.

Equity securities traded in the over-the-counter market, but excluding securities admitted to trading on the NASDAQ, are valued at the closing bid prices. Debt securities that are considered bonds are valued by using the bid price provided by an independent pricing service or, if such prices are not available or in the judgment of KAFA such prices are stale or do not represent fair value, by an independent broker. For debt securities that are considered bank loans, the fair market value is determined by using the bid price provided by the agent or syndicate bank or principal market maker. When price quotes for securities are not available, or such prices are stale or do not represent fair value in the judgment of KAFA, fair market value will be determined using the Company's valuation process for securities that are privately issued or otherwise restricted as to resale.

Exchange-traded options and futures contracts are valued at the last sales price at the close of trading in the market where such contracts are principally traded or, if there was no sale on the applicable exchange on such day, at the mean between the quoted bid and ask price as of the close of such exchange.

The Company may hold securities that are privately issued or otherwise restricted as to resale. For any security for which (a) reliable market quotations are not available in the judgment of KAFA, or (b) the independent pricing service or independent broker does not provide prices or provides a price that in the judgment of KAFA is stale or does not represent fair value, each shall be valued in a manner that most fairly reflects fair value of the security on the valuation date.

Unless otherwise determined by the Valuation Designee, the following valuation process is used for such securities:

• Valuation Designee. The applicable investments are valued monthly by KAFA, as the Valuation Designee, with new investments valued at the time such investment was made. The applicable investments are valued by senior professionals of KAFA who comprise KAFA's valuation committee. KAFA will specify the titles of the persons responsible for determining the fair value of Company investments, including by specifying the particular functions for which they are responsible, and will reasonably segregate fair value determinations from the portfolio management of the Company such that the portfolio manager(s) may not determine, or effectively determine by exerting substantial influence on, the fair values ascribed to portfolio investments.

• Valuation Firm. Quarterly, a third-party valuation firm engaged by KAFA reviews the valuation methodologies and calculations employed for these securities, unless the aggregate fair value of such security is less than 0.1% of the Company's total assets.

At February 28, 2026, the Company held 2.6% of its net assets applicable to common stockholders (1.9% of total assets) in securities that were fair valued pursuant to these procedures (Level 3 securities). The aggregate fair value of these securities at February 28, 2026, was $70,175. See Note 3 - Fair Value and Note 7 - Restricted Securities.

E. Security Transactions - Security transactions are accounted for on the date securities are purchased or sold (trade date). Realized gains and losses are calculated using the specific identification cost basis method for GAAP purposes. For tax purposes, the Company utilizes the average cost method to compute the adjusted tax cost basis of its MLP securities.

(amounts in 000's, except share and per share amounts)
(UNAUDITED)

F. Return of Capital Estimates - Dividends and distributions received from the Company's investments generally are comprised of income and return of capital. At the time such dividends and distributions are received, the Company estimates the amount of such payments that is considered investment income and the amount that is considered a return of capital. The Company estimates the return of capital portion of dividends and distributions received from investments based on historical information available and other information provided by certain investments. Return of capital estimates are adjusted to actual in the subsequent fiscal year when final tax reporting information related to the Company's investments is received.

The return of capital portion of the distributions is a reduction to investment income that results in an equivalent reduction in the cost basis of the associated investments and increases net realized gains (losses) and/or net change in unrealized gains (losses). In accordance with GAAP, the return of capital cost basis reductions for the Company's investments are limited to the total amount of the cash distributions received from such investments. If the distributions received by the Company exceed its cost basis (i.e., its cost basis has been reduced to zero), the distributions are treated as realized gains.

The Company includes all distributions received on its Statement of Operations and reduces its investment income by (i) the estimated return of capital and (ii) the distributions in excess of cost basis, if any. Distributions received that were in excess of cost basis were treated as realized gains.

The following table sets forth the Company's estimated return of capital portion of the dividends and distributions received from its investments that were not treated as distributions in excess of cost basis.

G. Investment Income - The Company records dividends and distributions on the ex-dividend date. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts. When investing in securities with paid-in-kind interest, the Company will accrue interest income during the life of the security even though it will not be receiving cash as the interest is accrued.

To the extent that interest income to be received is not expected to be realized, a reserve against income is established.

The Company may receive paid-in-kind and non-cash dividends and distributions in the form of additional units or shares from its investments. For paid-in-kind dividends, the additional units are not reflected in investment income during the period received, but are recorded as unrealized gains upon receipt. Non-cash distributions are reflected in investment income because the Company has the option to receive its distributions in cash or in additional units of the security. During the three months ended February 28, 2026, the Company did not receive any paid-in-kind dividends or non-cash distributions.

(amounts in 000's, except share and per share amounts)
(UNAUDITED)

H. Distributions to Stockholders - Distributions to common stockholders are recorded on the ex-dividend date. Distributions to holders of MRP Shares are accrued on a daily basis. As required by the Distinguishing Liabilities from Equity topic of the FASB Accounting Standards Codification (ASC 480), the Company includes the accrued distributions on its MRP Shares as an operating expense due to the fixed term of this obligation. For tax purposes, payments made to the holders of the Company's MRP Shares are treated as dividends or distributions.

The characterization of the distributions paid to holders of MRP Shares and common stock as either a dividend (eligible to be treated as qualified dividend income) or a distribution (return of capital) is determined after the end of the fiscal year based on the Company's actual earnings and profits and may differ substantially from preliminary estimates.

I. Partnership Accounting Policy - The Company records its pro-rata share of the income (loss), to the extent of distributions it has received, allocated from the underlying partnerships and adjusts the cost basis of the underlying partnerships accordingly. These amounts are included in the Company's Statement of Operations.

J. Taxes - The Company, as a corporation, is obligated to pay federal and state income tax on its taxable income. The Company invests in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Company includes its allocable share of the MLP's taxable income or loss in computing its own taxable income. Deferred income taxes reflect (i) taxes on unrealized gains (losses), which are attributable to the difference between fair value and tax cost basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and (iii) the net tax benefit of accumulated net operating and capital losses.

To the extent the Company has a deferred tax asset, consideration is given as to whether or not a valuation allowance is required. The need to establish a valuation allowance for deferred tax assets is assessed periodically by the Company based on the Income Tax Topic of the FASB Accounting Standards Codification (ASC 740), that it is more likely than not that some portion or all of the deferred tax asset will not be realized. In the assessment for a valuation allowance, consideration is given to all positive and negative evidence related to the realization of the deferred tax asset. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability (which are highly dependent on future cash distributions from the Company's holdings), the duration of statutory carryforward periods and the associated risk that certain loss carryforwards may expire unused.

The Company may rely to some extent on information provided by portfolio investments, which may not necessarily be timely, to estimate taxable income allocable to the units/shares of such companies held in the portfolio and to estimate the associated current and/or deferred tax liability. Such estimates are made in good faith. From time to time, as new information becomes available, the Company modifies its estimates or assumptions regarding the deferred tax liability. See Note 6 - Income Taxes.

The Company may be subject to withholding taxes on foreign-sourced income and accrues such taxes when the related income is earned.

The Company utilizes the average cost method to compute the adjusted tax cost basis of its MLP securities.

The Company's policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. Tax years subsequent to fiscal year 2021 remain open and subject to examination by federal and state tax authorities.

K. Derivative Financial Instruments - The Company may utilize derivative financial instruments in its operations and will do so in conformity with Rule 18f-4 under the 1940 Act.

Interest rate swap contracts. The Company may use hedging techniques such as interest rate swaps to mitigate potential interest rate risk on a portion of the Company's leverage. Such interest rate swaps would principally be used to protect the Company against higher costs on its leverage resulting from increases in interest rates. The Company does not hedge any interest rate risk associated with portfolio holdings. Interest rate transactions the Company may use for hedging purposes may expose it to certain risks that differ from the risks associated with its portfolio holdings. A decline in interest rates may result in a decline in the value of the swap contracts, which, everything else being held constant, would result in a decline in the net assets of the Company. In addition, if the counterparty to an interest rate swap defaults, the Company would not be able to use the anticipated net receipts under the interest rate swap to offset its cost of financial leverage.

Interest rate swap contracts are recorded at fair value with changes in value during the reporting period, and amounts accrued under the agreements, included as unrealized gains or losses in the Statement of Operations. Monthly cash settlements under the terms of the interest rate swap agreements or termination payments are recorded as realized gains or losses in the Statement of Operations. The Company generally values its interest rate swap contracts based on dealer quotations, if available, or by discounting the future cash flows from the stated terms of the interest rate swap agreement by using interest rates currently available in the market. See Note 8 - Derivative Financial Instruments.

Option contracts. The Company is also exposed to financial market risks including changes in the valuations of its investment portfolio. The Company may purchase or write (sell) call options. A call option on a security is a contract that gives the holder of the option, in return for a premium, the right to buy from the writer of the option the security underlying the option at a specified exercise price at any time during the term of the option.

The Company would realize a gain on a purchased call option if, during the option period, the value of such securities exceeded the sum of the exercise price, the premium paid and transaction costs; otherwise the Company would realize either no gain or a loss on the purchased call option. The Company may also purchase put option contracts. If a purchased put option is exercised, the premium paid increases the cost basis of the securities sold by the Company.

The Company may also write (sell) call options with the purpose of generating realized gains or reducing its ownership of certain securities. If the Company writes a call option on a security, the Company has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price. The Company will only write call options on securities that the Company holds in its portfolio (i.e., covered calls).

When the Company writes a call option, an amount equal to the premium received by the Company is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Company on the expiration date as realized gains from investments. If the Company repurchases a written call option prior to its exercise, the difference between the premium received and the amount paid to repurchase the option is treated as a realized gain or loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Company has realized a gain or loss. The Company, as the writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. See Note 8 - Derivative Financial Instruments.

(UNAUDITED)

L. Short Sales - A short sale is a transaction in which the Company sells securities it does not own (but has borrowed) in anticipation of or to hedge against a decline in the market price of the securities. To complete a short sale, the Company may arrange through a broker to borrow the securities to be delivered to the buyer. The proceeds received by the Company for the short sale are retained by the broker until the Company replaces the borrowed securities. In borrowing the securities to be delivered to the buyer, the Company becomes obligated to replace the securities borrowed at their market price at the time of replacement, whatever the price may be. The Company is liable for any interest, dividends or distributions paid on securities sold short.

The Company may also sell short "against the box" (i.e., the Company enters into a short sale as described above while holding an offsetting long position in the security which it sold short).

M. Foreign Currency Translations - The books and records of the Company are maintained in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on the following basis: (i) market value of investment securities, assets and liabilities at the rate of exchange as of the valuation date; and (ii) purchases and sales of investment securities, income and expenses at the relevant rates of exchange prevailing on the respective dates of such transactions.

The Company does not isolate that portion of gains and losses on investments in equity and debt securities which is due to changes in the foreign exchange rates from that which is due to changes in market prices of equity and debt securities. Accordingly, realized and unrealized foreign currency gains and losses with respect to such securities are included in the reported net realized and unrealized gains and losses on investment transactions balances.

Net realized foreign exchange gains or losses represent gains and losses from transactions in foreign currencies and foreign currency contracts, foreign exchange gains or losses realized between the trade date and settlement date on security transactions, and the difference between the amounts of interest and dividends recorded on the Company's books and the U.S. dollar equivalent of such amounts on the payment date.

Net unrealized foreign exchange gains or losses represent the difference between the cost of assets and liabilities (other than investments) recorded on the Company's books from the value of the assets and liabilities (other than investments) on the valuation date.

N. Indemnifications - Under the Company's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Company. In addition, in the normal course of business, the Company enters into contracts that provide general indemnification to other parties. The Company's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred, and may not occur. However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

O. Offering and Debt Issuance Costs - Offering costs incurred by the Company related to the issuance of its common stock reduce additional paid-in capital when the stock is issued. Costs incurred by the Company related to the issuance of its debt or its preferred stock are capitalized and amortized over the period the debt or preferred stock is outstanding.

KAYNE ANDERSON ENERGY INFRASTRUCTURE FUND, INC.
NOTES TO FINANCIAL STATEMENTS
(amounts in 000's, except share and per share amounts)
(UNAUDITED)

The Company has classified the costs incurred to issue its notes and preferred stock as a deduction from the carrying value on the Statement of Assets and Liabilities. For the purpose of calculating the Company's asset coverage ratios pursuant to the 1940 Act, deferred issuance costs are not deducted from the carrying value of debt or preferred stock.

P. Segment Reporting - The Company has adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The Company operates as a single operating segment. Subject to the oversight of the Company's Board of Directors, the Company's chief executive officer serves as the Chief Operating Decision Maker (CODM), assessing performance and making decisions about resource allocation for the Company. The CODM monitors the Company's operating results as a whole, and asset allocation is determined in accordance with the Company's investment objective and policies. The financial information provided to and reviewed by the CODM is consistent with that presented in the Company's financial statements. The adoption of this standard impacted only the Company's financial statement notes disclosures and did not affect the Company's financial position or results of operations.

Q. Consolidation - The Company follows the accounting and reporting guidance of FASB ASC 946. Accordingly, the Company generally does not consolidate its investments, including investments in operating companies or entities in which it may hold a controlling financial interest, unless such entity is itself an investment company or provides substantive services to the Company (such as investment advisory, administrative, or similar services). Investments that are not consolidated are recorded at fair value in accordance with the Company's valuation policies, with changes in fair value reflected in the Company's results of operations.

R. New Accounting Pronouncements - In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. The amendments enhance income tax disclosures by requiring disaggregation of annual income taxes paid by jurisdiction and qualitative disclosures related to reconciling items, while removing certain disclosure requirements. The ASU is effective for annual periods beginning after December 15, 2024, with early adoption permitted. Management is currently evaluating the impact of this guidance on its income tax disclosures and believes that the adoption of this ASU will not have a material impact on the financial statements.

3. Fair Value

The Fair Value Measurement Topic of the FASB Accounting Standards Codification (ASC 820) defines fair value as the price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants under current market conditions at the measurement date. As required by ASC 820, the Company has performed an analysis of all assets and liabilities (other than deferred taxes) measured at fair value to determine the significance and character of all inputs to their fair value determination. Inputs are the assumptions, along with considerations of risk, that a market participant would use to value an asset or a liability. In general, observable inputs are based on market data that is readily available, regularly distributed and verifiable that the Company obtains from independent, third-party sources. Unobservable inputs are developed by the Company based on its own assumptions of how market participants would value an asset or a liability.

KAYNE ANDERSON ENERGY INFRASTRUCTURE FUND, INC.
NOTES TO FINANCIAL STATEMENTS
(amounts in 000's, except share and per share amounts)
(UNAUDITED)

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into the following three broad categories.

• Level 1 - Valuations based on quoted unadjusted prices for identical instruments in active markets traded on a national exchange to which the Company has access at the date of measurement.

• Level 2 - Valuations based on quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or instances where prices vary substantially over time or among brokered market makers.

• Level 3 - Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect the Company's own assumptions that market participants would use to price the asset or liability based on the best available information.

The following table presents the Company's assets measured at fair value on a recurring basis at February 28, 2026, and the Company presents these assets by security type and description on its Schedule of Investments. Note that the valuation levels below are not necessarily an indication of the risk or liquidity associated with the underlying investment.

The Company did not have any liabilities that were measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at February 28, 2026.

As of February 28, 2026, the Company had Notes outstanding with an aggregate principal amount of $400,000 and 6,144,117 of MRP Shares outstanding with a total liquidation value of $153,603. See Note 11 - Notes and Note 12 - Preferred Stock.

All of the Notes and MRP Shares were issued in private placements to institutional investors and are not listed on any exchange or automated quotation system. The Company determines the fair value of these instruments based on estimated market yields and credit spreads for comparable instruments with similar maturity, terms and structure.

The Company records these Notes and MRP Shares on its Statement of Assets and Liabilities at principal amount or liquidation value. As of February 28, 2026, the estimated fair values of these leverage instruments were as follows:

Valuation Techniques and Unobservable Inputs

Ironwood Midstream Energy Partners III LLC ("IMEP III") is a privately-held operating company organized to acquire, build, own, and operate midstream assets. IMEP III is required to distribute all available cash through quarterly distributions, subject to debt covenants and necessary operating reserves. The Company holds Series A voting units ("IMEP III Series A Units") and Series B non-voting units ("IMEP III Series B Units"). The IMEP III Series A and Series B Units rank pari passu with respect to priority of distributions and liquidation preference and are senior to all other classes of equity. Other classes of equity participate in distributions only after the IMEP III Series A and Series B Units have received cash distributions sufficient for IMEP Series A and Series B investors to realize certain yield and return thresholds.

The Company uses a discounted cash flow model to value the IMEP III Series A and Series B Units under two operating scenarios. Each scenario is assigned a probability weighting to arrive at a weighted average value at a specified discount rate. The Company calculates probability weighted values over a range of discount rates and selects a value within such range as the fair value of the IMEP III Series A and Series B Units.

Sentinel Midstream Highline JV Holdings LLC ("Sentinel Midstream") is a privately-held company that operates energy infrastructure assets near the Texas and Louisiana Gulf Coast which are referred to as Enercoast Energy Infrastructure ("EEI"). The Company is the owner of Series A-2 units which represent a membership interest in Sentinel Midstream ("Sentinel-EEI Series A-2 Units"). The Sentinel-EEI Series A-2 Units are pari passu with Series A-1 and Series A-3 Units (together, "Series A Units"). The Series A Units are senior to other classes of common equity in terms of liquidation preference and priority of distributions. Other classes of common equity participate in distributions only after the Series A Units have received cash distributions sufficient for Series A investors to realize a 10% annualized return (IRR).

KAYNE ANDERSON ENERGY INFRASTRUCTURE FUND, INC.
NOTES TO FINANCIAL STATEMENTS
(amounts in 000's, except share and per share amounts)
(UNAUDITED)

As part of the process to determine the fair value of the Sentinel-EEI Series A-2 Units, KAFA utilizes two valuation methodologies. One of the methodologies is based on publicly-traded enterprise value to earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples for comparable companies and the second is based on a discounted cash flow model. A range of per share values is derived from these two methodologies. A per share value within the resulting range is then selected as the fair value.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company's investments may fluctuate from period to period. Additionally, the fair value of the Company's investments may differ from the values that would have been used had a ready market existed for such investments and may differ materially from the values that the Company may ultimately realize.

The following table summarizes the significant unobservable inputs that the Company used to value its portfolio investments categorized as Level 3 as of February 28, 2026:

Quantitative Table for Valuation Techniques

4. Risk Considerations

The Company's investments are concentrated in the energy sector. A downturn in one or more industries within the energy sector, material declines in energy-related commodity prices, adverse political, legislative or regulatory developments or environmental, catastrophic or other events could have a larger impact on the Company than on an investment company that does not concentrate in the energy sector. The performance of companies in the energy sector may lag the performance of other sectors or the broader market as a whole. The Company also invests in securities of foreign issuers, predominantly those located in Canada and, to a lesser extent, Europe. The value of those investments will fluctuate with market conditions, United States trade and economic policy, currency exchange rates and the economic and political climates of the foreign countries in which the issuers operate or are domiciled. Additionally, to the extent that the Company invests a relatively high percentage of its assets in the securities of a limited number of issuers, the Company may be more susceptible than a more widely diversified investment company to any single economic, political or regulatory occurrence.

("KMF") in November 2023, KAFA and the Company entered into an amended fee waiver agreement (the "Tier Waiver") with KYN to reduce the asset levels at which the fee waivers take effect under the Tier Waiver. The breakpoints under the Tier Waiver were reset at the time of the merger such that the Company pays a management fee of 1.375% on average total assets up to $2,282,690 (which was the pro forma amount of KYN and KMF total assets for purposes of calculating the management fee as of the closing of the merger); 1.250% on average total assets in excess of this amount and up to $4,000,000; 1.125% on average total assets between $4,000,000 and $6,000,000; and 1.000% on average total assets greater than $6,000,000. These tiered fee waivers result in a reduction to the effective management fee rate payable to KAFA as the Company's assets under management increase. The Tier Waiver has an initial 3-year term from the date of the merger and may be renewed annually thereafter upon approval of KAFA and the Company's Board of Directors (including a majority of the Company's directors who are not "interested persons" of the Company, as that term is defined in the 1940 Act (the "Independent Directors").

In addition to the Tier Waiver, KAFA also agreed to waive an additional amount of management fees (based on KYN and KMF assets at the closing of the merger) (the "Merger Waiver") such that pro forma management fees payable to KAFA would be equal to the aggregate management fee payable if KYN and

(UNAUDITED)

KMF had remained standalone companies. The Merger Waiver has a term of three years from the closing of the merger and was calculated to be $606 per year based on KYN and KMF's assets under management at the closing of the merger. The Merger Waiver expires on November 13, 2026. Any amount waived by KAFA pursuant to the Tier Waiver and/or Merger Waiver may not be recouped.

The investment management agreement has a current term through April 30, 2027 and may be renewed annually thereafter upon approval of KAFA and the Company's Board of Directors (including a majority of the Independent Directors). For the three months ended February 28, 2026, the Company paid management fees at an annual rate of 1.315% of the Company's average quarterly total assets (as defined in the investment management agreement).

For purposes of calculating the management fee, the average total assets for each quarterly period are determined by averaging the total assets at the last day of that quarter with the total assets at the last day of the prior quarter. The Company's total assets are equal to the Company's gross asset value (which includes assets attributable to the Company's use of preferred stock, commercial paper or notes and other borrowings and excludes any net deferred tax asset), minus the sum of the Company's accrued and unpaid dividends and distributions on any outstanding common stock and accrued and unpaid dividends and distributions on any outstanding preferred stock and accrued liabilities (other than liabilities associated with borrowing or leverage by the Company and any accrued taxes, including, a deferred tax liability). Liabilities associated with borrowing or leverage by the Company include the principal amount of any borrowings, commercial paper or notes issued by the Company, the liquidation preference of any outstanding preferred stock, and other liabilities from other forms of borrowing or leverage such as short positions and put or call options held or written by the Company.

C. Portfolio Companies - From time to time, the Company may "control" or may be an "affiliate" of one or more of its portfolio companies, as each of these terms is defined in the 1940 Act. In general, under the 1940 Act, the Company would be presumed to "control" a portfolio company if the Company and its affiliates owned 25% or more of its outstanding voting securities and would be an "affiliate" of a portfolio company if the Company and its affiliates owned 5% or more of its outstanding voting securities. The 1940 Act contains prohibitions and restrictions relating to transactions between investment companies and their affiliates (including the Company's investment adviser), principal underwriters and affiliates of those affiliates or underwriters.

The Company believes that there are several factors that determine whether or not a security should be considered a "voting security" in complex structures such as limited partnerships of the kind in which the Company invests. The Company also notes that the Securities and Exchange Commission (the "SEC") staff has issued guidance on the circumstances under which it would consider a limited partnership interest to constitute a voting security. Under most partnership agreements, the management of the partnership is vested in the general partner, and the limited partners, individually or collectively, have no rights to manage or influence management of the partnership through such activities as participating in the selection of the managers or the board of the limited partnership or the general partner. As a result, the Company believes that many of the limited partnership interests in which it invests should not be considered voting securities. However, it is possible that the SEC staff may consider the limited partner interests the Company holds in certain limited partnerships to be voting securities. If such a determination were made, the Company may be regarded as a person affiliated with and controlling the issuer(s) of those securities for purposes of Section 17 of the 1940 Act.

NOTES TO FINANCIAL STATEMENTS
(amounts in 000's, except share and per share amounts)
(UNAUDITED)

In making such a determination as to whether to treat any class of limited partnership interests the Company holds as a voting security, the Company considers, among other factors, whether or not the holders of such limited partnership interests have the right to elect the board of directors of the limited partnership or the general partner. If the holders of such limited partnership interests do not have the right to elect the board of directors, the Company generally has not treated such security as a voting security. In other circumstances, based on the facts and circumstances of those partnership agreements, including the right to elect the directors of the general partner, the Company has treated those securities as voting securities. If the Company does not consider the security to be a voting security, it will not consider such partnership to be an "affiliate" unless the Company and its affiliates own more than 25% of the outstanding securities of such partnership. Additionally, certain partnership agreements give common unitholders the right to elect the partnership's board of directors, but limit the amount of voting securities any limited partner can hold to no more than 4.9% of the partnership's outstanding voting securities (i.e., any amounts held in excess of such limit by a limited partner do not have voting rights). In such instances, the Company does not consider itself to be an affiliate if it owns more than 5% of such partnership's common units.

There is no assurance that the SEC staff will not consider that other limited partnership securities that the Company owns and does not treat as voting securities are, in fact, voting securities for the purposes of Section 17 of the 1940 Act. If such a determination were made, the Company would be required to abide by the restrictions on "control" or "affiliate" transactions as proscribed in the 1940 Act. The Company or any portfolio company that it controls, and its affiliates, may from time to time engage in certain of such joint transactions, purchases, sales and loans in reliance upon and in compliance with the conditions of certain exemptive rules promulgated by the SEC. The Company cannot make assurances, however, that it would be able to satisfy the conditions of these rules with respect to any particular eligible transaction, or even if the Company were allowed to engage in such a transaction, that the terms would be more or as favorable to the Company or any company that it controls as those that could be obtained in an arm's length transaction. As a result of these prohibitions, restrictions may be imposed on the size of positions that may be taken for the Company or on the type of investments that it could make.

Ironwood Midstream Energy Partners III LLC - IMEP III is a privately-held midstream operating company managed under the direction of its Board of Directors ("IMEP III Board") pursuant to the IMEP III LLC Agreement ("IMEP III LLCA"). The IMEP III Board is comprised of five members: three designated by IMEP III management and two designated by the Company. James C. Baker, Jr., Chairman, President and Chief Executive Officer of the Company, and Ron M. Logan, Jr., Executive Vice President of the Company, serve as the Company's appointed directors to the IMEP III Board.

The Company's investment in IMEP III includes both voting and non-voting equity interests, with its ownership of the IMEP III Series A Units representing 49% of the voting interests of IMEP III. In addition to its ownership of the voting securities of IMEP III, the Company possesses certain minority protective rights under the IMEP III LLCA, which require its consent before IMEP III may undertake specified corporate actions. Pursuant to the IMEP III Series A and Series B Unit Purchase Agreement ("IMEP III UPA"), the Company has committed to fund approximately $127,000 in additional capital to IMEP III. Any capital called pursuant to the IMEP III UPA must be authorized by the IMEP III Board and also requires the Company's prior written consent under its minority protective rights. This commitment is not included in the net assets of the Company as of February 28, 2026.

As the Company owns more than 25% of IMEP III's voting securities, IMEP III is considered a control affiliate of the Company for financial reporting purposes under the 1940 Act.

Sentinel Midstream Highline JV Holdings LLC - Pursuant to the terms of the Sentinel-EEI Series A-2 Units, Kayne Anderson has the right to designate one director of Sentinel Midstream for so long as Kayne Anderson and its affiliates continue to beneficially own at least 70% of its initial investment and at least 10% of the outstanding Series A units. Mr. Logan serves as the Kayne Anderson appointed director of Sentinel Midstream. The Company considers itself an affiliate of Sentinel Midstream under the 1940 Act by virtue of the Company's ownership interest in Sentinel Midstream and Kayne Anderson's director designation right.

The following table summarizes the Company's investments in affiliates as of and for the three months ended February 28, 2026:

6. Income Taxes

The Company's taxes include current and deferred income taxes. Current income taxes reflect the estimated income tax liability or asset of the Company as of a measurement date. Deferred income taxes reflect (i) taxes on net unrealized gains (losses), which are attributable to the difference between fair market value and tax cost basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and (iii) the net tax benefit of accumulated net operating losses and capital losses, if any.

As of February 28, 2026, the components of the Company's deferred tax assets and liabilities were as follows:

KAYNE ANDERSON ENERGY INFRASTRUCTURE FUND, INC.
NOTES TO FINANCIAL STATEMENTS
(amounts in 000's, except share and per share amounts)
(UNAUDITED)

During the three months ended February 28, 2026, the Company received $27 of tax refunds (net of $906 of tax payments).

As of February 28, 2026, the Company had a net current income tax receivable of $753, which was comprised of a net federal tax asset of $777 and a net state tax liability of $24.

As of February 28, 2026, the Company had capital loss carryforwards of $31,174 (federal and state deferred tax asset of $6,471 and $486, respectively). Realization of capital loss carryforwards is dependent on generating sufficient capital gains prior to their expiration. These capital loss carryforwards are associated with KYN's merger with KMF (as described below) and will expire if not used by fiscal 2028.

As of February 28, 2026, the Company had a federal net operating loss carryforward of $11,074, of which $4,647 is subject to the FMO Section 382 limitation described below (federal and state deferred tax asset of $2,325 and $428, respectively). Net operating losses can be carried forward indefinitely.

On March 4, 2022, the Company completed its merger with Fiduciary/Claymore Energy Infrastructure Fund ("FMO"). The merger qualified as a tax-free reorganization under Section 368(a) of the Internal Revenue Code (the "Code"). Upon completion of the merger, the Company acquired all of the tax attributes of FMO, including $6,310 of net operating losses. These net operating losses are subject to limitations as set forth in Section 382 of the Code which limit the amount of losses than can be utilized after a change in ownership. The annual FMO Section 382 limitation is $1,663.

On November 13, 2023, KYN completed its merger with KMF. The merger qualified as a tax-free reorganization under Section 368(a) of the Internal Revenue Code. Upon completion of the merger, the Company acquired all pre-merger KMF losses, including $355,751 of capital losses (subject to a five year carryforward period which expires in fiscal 2028). All pre-merger losses acquired from KMF, including the capital losses, are subject to limitations as set forth in Section 382 of the Code which limit the amount of losses that can be utilized after a change in ownership. The annual KMF Section 382 limitation is $15,587 per year. In addition, limitations under Section 384 of the Code further limit any losses acquired for a period of five years following the merger such that pre-merger losses of KMF may not be utilized to offset pre-merger gains of KYN (nor could pre-merger gains of KMF be offset against pre-merger losses of KYN).

As a result of limitations on these losses post-merger, the Company has written off the deferred tax asset associated with capital losses that exceed the portion of losses that will become available through the annual KMF Section 382 limitation (prior to the statutory expiration of the capital loss carryforward period). Following the merger, $78,670 of capital losses became available to the Company subject to the limitations described. Capital loss carryforwards acquired through the merger with KMF will expire if not utilized by fiscal year 2028.

For the three months ended February 28, 2026, the Company estimates it has realized sufficient post-merger gains to utilize $15,587 of acquired pre-merger KMF capital losses. As a result, the Company has reduced the valuation allowance previously established for these losses. After considering the capital loss carryforwards written off and/or utilized in prior periods, $31,174 of KMF capital loss carryforwards remain available for use in future years.

The Company periodically reviews the recoverability of its deferred tax assets based on the weight of available evidence. When assessing the recoverability of its deferred tax assets, significant weight is given to the effects of potential future realized and unrealized gains on investments and the time period over which these deferred tax assets can be utilized.

KAYNE ANDERSON ENERGY INFRASTRUCTURE FUND, INC.
NOTES TO FINANCIAL STATEMENTS
(amounts in 000's, except share and per share amounts)
(UNAUDITED)

As of February 28, 2026, the Company has determined that it is not more likely than not that all of its deferred tax assets would be realized through future taxable income of the appropriate character. Accordingly, a valuation allowance of $7,158 has been established, primarily related to the remaining losses acquired in the merger with KMF.

The Company will continue to review and assess the need for a valuation allowance in the future. Significant variability in the fair value of its portfolio of investments may change the Company's assessment regarding the recoverability of its deferred tax assets. If a further valuation allowance is required to reduce any deferred tax asset in the future, or if a change in a valuation allowance is necessary, it could have a material impact on the Company's net asset value and results of operations in the period of adjustment.

Total income taxes were different from the amount computed by applying the federal statutory income tax rate of 21% to the net investment income (loss) and realized and unrealized gains (losses) on investments before taxes as follows:

As a limited partner of MLPs, the Company includes its allocable share of such MLP's income or loss in computing its own taxable income or loss. Additionally, for income tax purposes, the Company reduces the cost basis of its MLP investments by the cash distributions received, and increases or decreases the cost basis of its MLP investments by its allocable share of the MLP's income or loss. During the three months ended February 28, 2026, the Company decreased its tax cost basis by approximately $37,586 due to 2025 net allocated losses (after considering Section 163(j) limitations on the deduction for business interest expense) from its MLP investments.

The Company utilizes the average cost method to compute the adjusted tax cost basis of its MLP securities.

As of February 28, 2026, the cost basis of investments for federal income tax purposes was $1,815,379. The cost basis for federal income tax purposes is $509,886 lower than the cost basis for GAAP reporting purposes primarily due to the additional basis adjustments attributable to the Company's share of the cumulative allocated losses from its MLP investments. At February 28, 2026, gross unrealized appreciation and depreciation of investments and options, if any, for federal income tax purposes were as follows:

For the fiscal year ended November 30, 2025, of the $162,361 of distributions paid to common stockholders, $125,056 was characterized as dividend income (eligible to be treated as qualified dividend income) and $37,305 was characterized as return of capital. Distributions of $6,160 paid to holders of MRP Shares were characterized as dividends (eligible to be treated as qualified dividend income). These characterizations are based on the Company's earnings and profits.

7. Restricted Securities
