COHEN & STEERS INFRASTRUCTURE FUND, INC.

To Our Shareholders:

We would like to share with you our report for the six months ended June 30, 2011. The net asset value (NAV) at that date was $19.73 per common share. The Fund's common stock is traded on the New York Stock Exchange (NYSE) and its share price can differ from its NAV; at period end, the Fund's closing price on the NYSE was $17.80.

The total returns, including income, for the Fund and its comparative benchmarks were:

	Six Months Ended June 30, 2011
Cohen & Steers Infrastructure Fund at Market Value^a		12.77	%
Cohen & Steers Infrastructure Fund at NAV^a		10.76	%
UBS Global 50/50 Infrastructure & Utilities Index—Net^b		5.37	%
Blended benchmark—80% UBS Global 50/50 Infrastructure & Utilities Index—Net/20% BofA Merrill Lynch Fixed Rate Preferred Index^b		5.41	%
S&P 500 Index^b		6.02	%

The performance data quoted represent past performance. Past performance is no guarantee of future results. The investment return and the principal value of an investment will fluctuate and shares, if sold, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. Performance results reflect the effects of leverage, resulting from borrowings under a credit agreement. Current total returns of the Fund can be obtained by visiting our Web site at cohenandsteers.com.

The Fund implements fair value pricing when the daily change in a specific U.S. market index exceeds a predetermined percentage. Fair value pricing adjusts the valuation of non-U.S. holdings to account for such index change following the close of foreign markets. This standard practice has been adopted by a majority of the fund industry to deter investors from arbitraging funds with a large percentage of non-U.S. holdings. In the event fair value pricing is implemented on the first and/or last day of a performance measurement period, the Fund's return may diverge from the relative performance of its benchmark index, which does not use fair value pricing. An investor cannot invest directly in an index.

^a As a closed-end investment company, the price of the Fund's NYSE-traded shares will be set by market forces and at times may deviate from the NAV per share of the Fund.

^b The UBS Global 50/50 Infrastructure & Utilities Index tracks the performance of global infrastructure-related securities, split evenly between utilities and infrastructure and is net of dividend withholding taxes. The BofA Merrill Lynch Fixed Rate Preferred Index is an unmanaged index of preferred securities. The S&P 500 Index is an unmanaged index of common stocks that is frequently used as a general measure of stock market performance.

COHEN & STEERS INFRASTRUCTURE FUND, INC.

The Fund makes regular quarterly distributions at a level rate (the "Policy"). Distributions paid by the Fund are subject to recharacterization for tax purposes and are taxable up to the amount of the Fund's investment company taxable income and net realized gains. As a result of the Policy, the Fund may pay distributions in excess of the Fund's investment company taxable income and realized gains. This excess would be a "return of capital" distributed from the Fund's assets. Distributions of capital decrease the Fund's total assets and, therefore, could have the effect of increasing the Fund's expense ratio. In addition, in order to make these distributions, the Fund may have to sell portfolio securities at a less than opportune time.

Investment Review

Global equity markets got off to a strong start in 2011 amid optimism that global economic expansion would continue. Macroeconomic factors and geopolitical events soon presented challenges, however. Turbulence in North Africa and the Middle East drove oil prices above $100 a barrel in the first quarter, while the events in Japan roiled financial markets in general and the listed infrastructure universe in particular. (Japanese infrastructure companies accounted for about 18% of the UBS Global 50/50 Infrastructure and Utilities Index.) Investors moved into less-risky assets, which benefited global infrastructure securities.

Most infrastructure sectors advanced

Most sectors advanced, led by gas pipelines. In February, the group was lifted by news that Williams Companies would spin off its exploration & production division and concentrate on its midstream and pipeline businesses. Investors responded favorably, and Williams' stock rose 26% in the first quarter. In the second quarter, El Paso Corp., another pipeline company, announced its intention to do the same. In addition, a takeover battle and bidding war developed for pipeline operator Southern Union (which is not in the index).

Some defensive sectors struggled

Toll roads advanced in the first quarter, but struggled in the second, when China's government said it will review, and possibly reduce, expressway tolls as a way to combat inflation. Electric utilities faced headwinds created by the Fukushima disaster. Utilities in Japan had particularly steep declines due to concerns that they all may be required to shoulder a victim compensation plan. Germany's decision to suspend operations immediately at seven older nuclear plants, with a goal of phasing out all nuclear-generated power in the country by 2022, also hurt the sector.

Airports benefited from economic expansion and increased traffic in the first quarter. Somewhat counter-intuitively for a cyclical sector, they also outperformed in the second quarter, with European and Australian airports doing particularly well. The railways sector, which consists entirely of Japanese companies within the index, had a steep decline—a reflection of the expected slowdown in passenger traffic as a result of the tsunami.

COHEN & STEERS INFRASTRUCTURE FUND, INC.

Preferred securities had strong performance

Preferred securities performed well early on amid good earnings reports from the financial sector and signs of an improving economy. Even though second-quarter economic data was disappointing, preferreds added to their gains when a flight to safety drove Treasury yields lower, to the benefit of fixed income assets broadly.

Fund performance

The Fund had a positive return for the year to date and outperformed its benchmark. Relative performance was enhanced by our underweight in railways and stock selection in electric utilities and the towers and satellites sector. We were overweight two continental European satellite companies that were seen as safe havens, and underweight a UK company whose core business margins declined. Our overweight in gas pipelines also boosted relative return, although stock selection muted some of that benefit. We believe the market does not yet fully appreciate the value of pipeline assets in the ground as well as significant expansion opportunities—and acquisition activity during the period would seem to support our view.

Stock selection in the toll roads and railways sectors detracted from relative return. Within toll roads, we were overweight two Chinese companies that declined. We also owned a Japanese railway that faces significant short-term challenges, but that we believe offers long-term value.

Our allocation to preferred securities and corporate debt had a positive impact on relative returns, with the Fund's fixed income holdings performing substantially better than the benchmark.

The Fund employs leverage as part of a yield-enhancement strategy. Leverage, which can increase total return in rising markets (just as it can have the opposite effect in declining markets), boosted the Fund's performance for the year to date compared with its benchmarks, which are not leveraged.

Impact of derivatives on Fund performance

The Fund is leveraged using bank borrowings and pays a floating rate of interest on these borrowings. It has employed interest rate swaps with the purpose of reducing the impact of a potential increase in interest rates, which would negatively affect earnings. The swaps exchange a floating-rate payment for a fixed-rate payment. Although employed as a hedge, the swaps are marked to market daily and can contribute positively or negatively to the net asset value of the Fund. For the six months ended June 30, 2011, the Fund's use of swaps had a negative impact on the NAV and performance of the Fund.

The Fund also sold covered call options on a security with the intention of earning option premiums, potentially increasing distributable income and reducing volatility. The use of these options did not have a material impact on performance during the period.

COHEN & STEERS INFRASTRUCTURE FUND, INC.

Investment Outlook

The global recovery will continue to support infrastructure fundamentals in both emerging and developed economies, in our view. Although regulatory risk remains a concern, governments generally acknowledge the need to encourage private infrastructure investment by allowing attractive rates of return. We also expect to see an increase in acquisitions, as companies put their strengthened balance sheets to use and fiscally strained governments continue to sell infrastructure assets.

With many leading economic indicators in developed regions peaking, we have increased portfolio weightings in the more defensive subsectors, including regulated utilities, and lowered our weightings in the more economically sensitive subsectors, such as transportation infrastructure. Regionally, we remain most cautious on Europe, as we believe the austerity measures needed to reduce deficits are likely to have a long-lasting impact on economic growth.

With respect to Japan, we believe that recent events will have a material negative effect on the country's medium-term economic growth outlook, but that investment opportunities will exist in cases where valuations overshoot relative to our fundamental views. We further believe that nuclear power will remain an important source of electricity globally, although regulatory and safety-related cost increases are likely and scrutiny over new plant development and license extensions will persist.

Regarding preferred securities, the most recent readings on global developed economies have led us to take a somewhat more cautious approach. We have reduced our allocation to banks we believe are vulnerable to a global slowdown, and increased allocations to less cyclical industries, including utilities and telecommunications companies.

We expect new supply to come mostly from non-bank issuers, including REITs and other non-financial companies. Banks will likely remain on the sidelines until there is more regulatory clarity. We will continue to look for value in transactions priced around the globe and across various currencies.

Our Leverage Strategy (Unaudited)

Our current leverage strategy utilizes borrowings up to the maximum permitted by the 1940 Act to provide additional capital for the Fund, with an objective of increasing the net income available for shareholders. As of June 30, 2011, leverage represented 33% of the Fund's managed assets.

It has been our philosophy to utilize interest rate swap transactions to seek to reduce the interest rate risk inherent in our utilization of leverage. Considering that borrowings have variable interest rate payments, we seek to lock in those rates on a significant portion of this additional capital through interest rate swap agreements (where we effectively convert our variable rate obligation to a fixed rate obligation for the term of the swap agreements). Specifically, as of June 30, 2011, we have fixed the rate on 71% of our borrowings at an average interest rate of 3.0% for an average remaining period of 2.9 years (when we first entered into the swaps, the average term was 5.2 years). Locking in a significant portion of our leveraging costs is designed to protect the dividend-paying ability of the Fund. The use of leverage increases the volatility of the Fund's net asset value in both up and down markets. However, we believe that locking in a portion of the Fund's leveraging costs for the term of the swap agreements partially protects the Fund's expenses from an increase in short-term interest rates although this strategy will increase expenses when the rate on the Fund's borrowings is below the weighted average rate on the swaps.

Leverage Facts^a

Leverage (as a % of managed assets)	33	%
% Fixed Rate	71	%
% Variable Rate	29	%
Weighted Average Rate on Swaps	3.0	%
Weighted Average Term on Swaps	2.9 years
Current Rate on Borrowings^b	1.2	%

The Fund seeks to enhance its dividend yield through leverage. The use of leverage is a speculative technique and there are special risks and costs associated with leverage. The net asset value of the Fund's common shares may be reduced by the issuance and ongoing costs of leverage. So long as the Fund is able to invest in securities that produce a realized investment yield that is greater than the total cost of leverage, the leverage strategy will produce higher current net investment income for the common shareholders. On the other hand, to the extent that the total cost of leverage exceeds the incremental income gained from employing such leverage, the common shareholders would realize lower net investment income. In addition to the impact on net income, the use of leverage will have an effect of magnifying capital appreciation or depreciation for common shareholders. Specifically, in an up market, leverage will typically generate greater capital appreciation than if the Fund was not employing leverage. Conversely, in down markets, the use of leverage will generally result in greater capital depreciation than if the Fund had been unlevered. To the extent that the Fund is required or elects to reduce its leverage, the Fund may need to liquidate investments, including under adverse economic conditions which may result in capital losses potentially reducing returns to common shareholders. There can be no assurance that a leveraging strategy will be successful during any period in which it is employed.

Note 1. Significant Accounting Policies

Cohen & Steers Infrastructure Fund, Inc. (the Fund) was incorporated under the laws of the State of Maryland on January 8, 2004 and is registered under the Investment Company Act of 1940 as amended, as a nondiversified closed-end management investment company. The Fund's investment objective is total return with emphasis on income.

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America (GAAP). The preparation of the financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Portfolio Valuation: Investments in securities that are listed on the New York Stock Exchange are valued, except as indicated below, at the last sale price reflected at the close of the New York Stock Exchange 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 closing bid and asked prices on such day or, if no asked price is available, at the bid price. Exchange traded options are valued at their last sale price as of the close of options trading on applicable exchanges. In the absence of a last sale, options are valued at the average of the quoted bid and asked prices as of the close of business. Over-the-counter options quotations are provided by the respective counterparty when such prices are believed by Cohen & Steers Capital Management, Inc. (the investment manager), pursuant to delegation by the Board of Directors, to reflect the fair market value.

Securities not listed on the New York Stock Exchange but listed on other domestic or foreign securities exchanges are valued in a similar manner. 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 as reflected on the tape at the close of the exchange representing the principal market for such securities. If after the close of a foreign market, but prior to the close of business on the day the securities are being valued, market conditions change significantly, certain foreign securities may be fair valued pursuant to procedures established by the Board of Directors.

Readily marketable securities traded in the over-the-counter market, including listed securities whose primary market is believed by the investment manager to be over-the-counter, are valued at the official closing prices as reported by sources as the Board of Directors deem appropriate to reflect their fair market value. If there has been no sale on such day, the securities are valued at the mean of the closing bid and asked prices on such day, or if no asked price is available, at the bid price. However, certain fixed-income securities may be valued on the basis of prices provided by a pricing service when such prices are believed by the investment manager, pursuant to delegation by the Board of Directors, to reflect the fair market value of such securities.

Securities for which market prices are unavailable, or securities for which the investment manager determines that the bid and/or asked price or a counterparty valuation does not reflect market value, will be valued at fair

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

value pursuant to procedures approved by the Fund's Board of Directors. Circumstances in which market prices may be unavailable include, but are not limited to, when trading in a security is suspended, the exchange on which the security is traded is subject to an unscheduled close or disruption or material events occur after the close of the exchange on which the security is principally traded. In these circumstances, the Fund determines fair value in a manner that fairly reflects the market value of the security on the valuation date based on consideration of any information or factors it deems appropriate. These may include, but are not limited to, recent transactions in comparable securities, information relating to the specific security and developments in the markets. Interest rate swaps are valued utilizing quotes received from an outside pricing service.

The Fund's use of fair value pricing may cause the net asset value of Fund shares to differ from the net asset value that would be calculated using market quotations. Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security may be materially different than the value that could be realized upon the sale of that security.

Short-term debt securities with a maturity date of 60 days or less are valued at amortized cost, which approximates value. Investments in open-end mutual funds are valued at their closing net asset value.

Fair value is defined as the price that the Fund would receive to sell an investment or pay to transfer a liability in an orderly transaction with an independent buyer in the principal market, or in the absence of a principal market the most advantageous market for the investment or liability. The hierarchy of inputs that are used in determining the fair value of the Fund's investments is summarized below.

• Level 1 – quoted prices in active markets for identical investments

• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, credit risk, etc.)

• Level 3 – significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

When foreign fair value pricing procedures are utilized, securities are categorized as Level 2. The utilization of these procedures results in transfers between Level 1 and Level 2. 61.5% of net assets of the Fund were fair valued pursuant to foreign fair value pricing procedures approved by the Board of Directors. The following is a summary of the inputs used as of June 30, 2011 in valuing the Fund's investments carried at value:

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

Security Transactions and Investment Income: Security transactions are recorded on trade date. Realized gains and losses on investments sold are recorded on the basis of identified cost. Interest income is recorded on the accrual basis. Discounts are accreted and premiums are amortized over the life of the respective securities. Dividend income is recorded on the ex-dividend date, except for certain dividends on foreign securities, which are recorded as soon as the Fund is informed after the ex-dividend date. The Fund records distributions received in excess of income from underlying investments as a reduction of cost of investments and/or an increase in realized gain. Such amounts are based on estimates if actual amounts are not available, and actual amounts of income, realized gain and return of capital may differ from the estimated amounts. The Fund adjusts the estimated amounts of the components of distributions (and consequently its net investment income) as an increase to unrealized appreciation/(depreciation) and realized gain/(loss) on investments as necessary once the issuers provide information about the actual composition of the distributions.

Options: The Fund may write put or call options on an index and put and covered call options on a security with the intention of earning option premiums. Option premiums may increase the Fund's realized gains and therefore may help increase distributable income. When a Fund writes (sells) an option, an amount equal to the premium received by the Fund is recorded in the Statement of Assets and Liabilities as a liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When an option expires, the Fund realizes a gain on the option to the extent of the premiums received. Premiums received from writing options which are exercised or closed, are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. If a put option on a security is exercised, the premium reduces the cost basis of the security purchased by the Fund. If a call option is exercised, the call premium is added to the proceeds of the security sold to determine its gain or loss. The Fund, as writer of an option, bears the market risk of an unfavorable change in the price of the underlying index or security. Other risks include the possibility of an illiquid options market or the inability of the counterparties to fulfill their obligations under the contract.

Foreign Currency Translations: The books and records of the Fund are maintained in U.S. dollars as follows: (1) the foreign currency market value of investment securities, other assets and liabilities and foreign currency contracts are translated at the exchange rates prevailing at the end of the period; and (2) purchases, sales, income and expenses are translated at the exchange rates prevailing on the respective dates of such transactions. The resultant exchange gains and losses are recorded as realized and unrealized gain/loss on foreign exchange transactions. Pursuant to U.S. federal income tax regulations, certain foreign exchange gains/losses included in realized and unrealized gain/loss are included in or are a reduction of ordinary income for federal income tax purposes. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in the market prices of the securities.

Foreign Securities: The Fund may directly purchase securities of foreign issuers. Investing in securities of foreign issuers involves special risks not typically associated with investing in securities of U.S. issuers. The risks

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

include possible revaluation of currencies, the ability to repatriate funds, less complete financial information about companies and possible future adverse political and economic developments. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than those of securities of comparable U.S. issuers.

Interest Rate Swaps: The Fund uses interest rate swaps in connection with borrowing under its credit agreement. The interest rate swaps are intended to reduce the risk that an increase in short-term interest rates could have on the performance of the Fund's common shares as a result of the floating rate structure of interest owed pursuant to the credit agreement. In these interest rate swaps, the Fund agrees to pay the other party to the interest rate swap (which is known as the counterparty) a fixed rate payment in exchange for the counterparty agreeing to pay the Fund a variable rate payment that is intended to approximate the Fund's variable rate payment obligation on the credit agreement. The payment obligation is based on the notional amount of the swap. Depending on the state of interest rates in general, the use of interest rate swaps could enhance or harm the overall performance of the common shares. The market value of interest rate swaps is based on pricing models that consider the time value of money, volatility, the current market and contractual prices of the underlying financial instrument. Unrealized appreciation is reported as an asset and unrealized depreciation is reported as a liability on the Statement of Assets and Liabilities. The change in value of swaps, including the accrual of periodic amounts of interest to be paid or received on swaps, is reported as unrealized appreciation or depreciation in the Statement of Operations. A realized gain or loss is recorded upon payment or receipt of a periodic payment or termination of swap agreements. Swap agreements involve, to varying degrees, elements of market and counterparty risk, and exposure to loss in excess of the related amounts reflected in the Statement of Assets and Liabilities. The Fund's maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from the counterparty over the contract's remaining life, to the extent that such amount is positive.

For each swap counterparty, the Fund entered into an International Swap and Derivatives Association Inc. Master Agreement and related annexes thereto ("ISDAs") which sets forth the general terms and conditions of the Fund's swap transactions. During 2008, the Fund notified Merrill Lynch Derivative Products AG ("MLDP") and UBS AG ("UBS") that it breached certain terms and conditions of its ISDAs. During 2009, the Fund notified UBS of additional breaches. On November 21, 2008, UBS granted a conditional waiver to the Fund stating that UBS did not intend to presently exercise its rights under the ISDA. MLDP has required that the Fund post collateral in the form of cash or U.S. Treasury securities. The collateral amount is determined by the approximate unrealized depreciation of a particular swap transaction on each valuation date. As of June 30, 2011, this amount was $6,770,000 and was pledged in cash by the Fund to MLDP. At June 30, 2011, the Fund continues to operate under the existing terms of all of its various ISDAs, including those with MLDP and UBS. However, MLDP and UBS reserve any and all rights to take any future action with respect to such events, including termination of outstanding swap transactions; termination or renegotiation of the ISDAs; requiring posting of collateral in the form of cash or U.S. Treasury securities representing the unrealized depreciation on outstanding interest rate swap transactions or

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

continuation under the current terms of the ISDAs. Any action resulting in the early termination of an interest rate swap transaction would cause the Fund to realize any market depreciation that existed on such transaction. In addition to realizing such losses, the early termination of a swap transaction may generate additional expenses for the Fund.

Dividends and Distributions to Shareholders: Dividends from net investment income and capital gain distributions are determined in accordance with U.S. federal income tax regulations, which may differ from GAAP. Dividends from net investment income, if any, are declared and paid quarterly. Net realized capital gains, unless offset by any available capital loss carryforward, are typically distributed to shareholders at least annually. Dividends and distributions to shareholders are recorded on the ex-dividend date and are automatically reinvested in full and fractional shares of the Fund in accordance with the Fund's Reinvestment Plan unless the shareholder has elected to have them paid in cash. Distributions paid by the Fund are subject to recharacterization for tax purposes.

Income Taxes: It is the policy of the Fund to continue to qualify as a regulated investment company, if such qualification is in the best interest of the shareholders, by complying with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies, and by distributing substantially all of its taxable earnings to its shareholders. Accordingly, no provision for federal income or excise tax is necessary. Dividend and interest income from holdings in non-U.S. securities is recorded net of non-U.S. taxes paid. Management has analyzed the Fund's tax positions taken on federal income tax returns as well as its tax positions in non-U.S. jurisdictions where it trades for all open tax years and has concluded that as of June 30, 2011, no additional provisions for income tax would be required in the Fund's financial statements. The Fund's tax positions for the tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service, state departments of revenue and by foreign tax authorities.

Note 2. Investment Management Fees, Administration Fees and Other Transactions with Affiliates

Investment Management Fees: The investment manager serves as the Fund's investment manager pursuant to an investment management agreement (the investment management agreement). Under the terms of the investment management agreement, the investment manager provides the Fund with day-to-day investment decisions and generally manages the Fund's investments in accordance with the stated policies of the Fund, subject to the supervision of the Board of Directors.

For the services under the investment management agreement, the Fund pays the investment manager an investment management fee, accrued daily and paid monthly, at an annual rate of 0.85% of the Fund's average daily managed asset value. Managed asset value is the net asset value of the common shares plus the amount of any borrowings used for leverage outstanding.

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

The investment manager has contractually agreed to waive its investment management fee as follows:

For the Period	Percentage of Average Daily Managed Asset Value
4/01/10—3/31/11		0.10	%
4/01/11—3/31/12		0.05	%

During the six months ended June 30, 2011, the investment manager waived its fee at the annual rate of 0.075%.

Under sub-advisory agreements between the investment manager and each of Cohen & Steers Asia Limited, Cohen & Steers UK Limited and Cohen & Steers Europe S.A. (collectively the subadvisors), affiliates of the investment manager, the subadvisors are responsible for managing the Fund's investments in certain non-U.S. real estate securities. For their services provided under the sub-advisory agreements, the investment manager (not the Fund) pays the subadvisors. The investment manager allocates 50% of the investment management fee received from the Fund among itself and each subadvisor based on the portion of the Fund's average assets managed by the investment manager and each subadvisor.

Administration Fees: The Fund has entered into an administration agreement with the investment manager under which the investment manager performs certain administrative functions for the Fund and receives a fee, accrued daily and paid monthly, at the annual rate of 0.06% of the Fund's average daily managed assets up to $1 billion, 0.04% of the Fund's average daily managed assets in excess of $1 billion up to $1.5 billion and 0.02% of the Fund's average daily managed assets in excess of $1.5 billion. For the six months ended June 30, 2011, the Fund incurred $496,917 in administration fees. Additionally, the Fund pays State Street Bank and Trust Company as co-administrator under a fund accounting and administration agreement.

Directors' and Officers' Fees: Certain directors and officers of the Fund are also directors, officers, and/or employees of the investment manager. The Fund does not pay compensation to any affiliated directors and officers except for the Chief Compliance Officer, who received $20,027 from the Fund for the six months ended June 30, 2011.

Note 3. Purchases and Sales of Securities

Purchases and sales of securities, excluding short-term investments, for the six months ended June 30, 2011, totaled $674,123,170 and $688,508,891, respectively.

Gross unrealized appreciation	$	335,276,976
Gross unrealized depreciation		(32,893,625	)
Net unrealized appreciation	$	302,383,351

As of December 31, 2010, the Fund had a net capital loss carryforward of $169,981,393, of which $27,597,582 will expire on December 31, 2015 and $142,383,811 will expire on December 31, 2016. This carryforward may be used to offset future capital gains to the extent provided by regulations. All of the net capital loss carryforward was acquired from the Fund's merger with Cohen & Steers REIT & Utility Income Fund, Inc. ("RTU")(See Note 10). Federal tax rules limit the Fund's use of this capital loss carryforward. The Regulated Investment Company Modernization Act of 2010 (the "Act") requires that capital loss carryforwards incurred after the effective date of the Act be used before those previously incurred, thereby increasing the chances that all or a portion of these losses will not be able to be utilized prior to their expiration.

Note 5. Capital Stock

The Fund is authorized to issue 300 million shares of common stock at a par value of $0.001 per share.

During the six months ended June 30, 2011 and the year ended December 31, 2010, the Fund issued no shares of common stock for the reinvestment of dividends.

On December 14, 2010, the Board of Directors approved the continuation of the delegation of its authority to management to effect repurchases, pursuant to management's discretion and subject to market conditions and investment considerations, of up to 10% of the Fund's common shares outstanding ("Share Repurchase Program")

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

as of January 1, 2011 through the fiscal year ended December 31, 2011. During the six months ended June 30, 2011, the Fund did not effect any repurchases. During the year ended December 31, 2010, the Fund repurchased 587,239 Treasury shares of its common stock at an average price of $13.44 per share (including brokerage commissions) at a weighted average discount of 16.3%. These repurchases, which had a total cost of $7,892,925, resulted in an increase of $0.02 to the Fund's net asset value per share.

Note 6. Borrowings

The Fund had a $850,000,000 revolving credit agreement (the credit agreement) with BNP Paribas Prime Brokerage Inc. (BNPP). The Fund pays a facility fee of 0.55% per annum (prior to May 19, 2011, the rate was 0.95%) on the unused portion of the credit agreement. The credit agreement has a 270-day rolling term that resets daily; however, if the Fund exceeds certain net asset value triggers, the credit agreement may convert to a 60-day rolling term that resets daily. The Fund is required to pledge portfolio securities as collateral in an amount up to two times the loan balance outstanding and has granted a security interest in the securities pledged to, and in favor of, BNPP as security for the loan balance outstanding. If the Fund fails to meet certain requirements, or maintain other financial covenants required under the credit agreement, the Fund may be required to repay immediately, in part or in full, the loan balance outstanding under the credit agreement necessitating the sale of portfolio securities at potentially inopportune times. The credit agreement also permits, subject to certain conditions, BNPP to rehypothecate portfolio securities pledged by the Fund up to the amount of the loan balance outstanding. The Fund continues to receive dividends and interest on rehypothecated securities. The Fund also has the right under the credit agreement to recall the rehypothecated securities from BNPP on demand. If BNPP fails to deliver the recalled security in a timely manner, the Fund will be compensated by BNPP for any fees or losses related to the failed delivery or, in the event a recalled security will not be returned by BNPP, the Fund, upon notice to BNPP, may reduce the loan balance outstanding by the amount of the recalled security failed to be returned. The Fund will receive a portion of the fees earned by BNPP in connection with the rehypothecation of portfolio securities.

As of June 30, 2011, the Fund has outstanding borrowings of $850,000,000. During the six months ended June 30, 2011, the Fund borrowed an average daily balance of $838,635,359 at a weighted average borrowing cost of 1.28%. As of June 30, 2011, the aggregate value of rehypothecated securities was $796,596,048. During the six months ended June 30, 2011, the Fund earned $196,704 in fees from rehypothecated securities.

Note 8. Legal Proceedings

The Board of Directors of the Fund received a letter from a law firm on behalf of purported holders of the Fund's common shares demanding that the Board of Directors take action against the investment manager and the Fund's directors and officers to recover, for the benefit of the Fund, alleged damages related to such parties' alleged breaches of fiduciary duties related to the redemption of the Fund's auction preferred shares at their liquidation preference. In response to the demand letter, the Fund's Board of Directors established a committee of independent directors to investigate the claims, and the committee retained independent counsel to assist it in conducting its investigation (the "Special Committee").

Subsequently, the Fund was named as a nominal defendant in a putative shareholder derivative action captioned Gammon v. Cohen & Steers Capital Management, Inc., et al. filed in the Supreme Court of the State of New York, County of New York on August 26, 2010 (the "Complaint"). The Complaint, filed purportedly on behalf, and for the benefit, of the Fund, name as defendants the investment manager, Cohen & Steers, Inc., the investment manager's parent company, and the Fund's current officers, including the two Interested Directors (collectively, the "Defendants"), and name the Fund as a nominal defendant. The Complaint contains the same basic allegations contained in the demand letter and seeks a declaration that the investment manager and Fund officers have breached their fiduciary duties, indeterminate monetary damages in favor of the Fund and an award of plaintiffs' costs and disbursements in pursuing the action. In derivative actions, Maryland law requires a report to shareholders when indemnification or expense advances are provided to Directors. The respective Funds are

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

hereby reporting that the Interested Directors, along with the other Defendants, received indemnification and expense advances with respect to the Complaint.

On November 1, 2010, after an extensive investigation conducted with the assistance of independent counsel, the Special Committee determined that the Fund should not pursue claims based on the allegations in the demand letter and rejected the demands made in the letter.

On April 14, 2011, Cohen & Steers, Inc. announced the voluntary dismissal by plaintiffs of the Complaint in its entirety with prejudice. The court approved the dismissal without any settlement or concessions by the Defendants or Fund.

Note 9. Other

In the normal course of business, the Fund enters into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is dependent on claims that may be made against the Fund in the future and, therefore, cannot be estimated; however, based on experience, the risk of material loss from such claims is considered remote.

Note 10. Merger

On June 29, 2009, the Boards of Directors of the Fund and RTU approved a proposal, subject to approval by each fund's shareholders, in which RTU would merge with and into the Fund in accordance with Maryland General Corporation Law. The purpose of the transaction was to combine two funds managed by the investment manager with comparable investment objectives and strategies. On November 24, 2009, RTU's shareholders approved the merger. However, after multiple adjournments, the Fund failed to receive a sufficient number of votes to also approve the merger. On December 10, 2009, the Fund's Board of Directors determined that the merger remained in the best interest of shareholders and set new record and shareholder meeting dates of December 17, 2009 and February 26, 2010, respectively.

On February 26, 2010, the Fund's shareholders approved the merger with RTU and as of the close of business on March 12, 2010, the Fund acquired all the net assets of RTU with the investment portfolio constituting the principal asset. The acquisition was accomplished by a tax-free exchange of 58,858,135 shares worth $753,236,069 of RTU for 43,234,832 shares of the Fund. The net assets of RTU and the Fund immediately before the acquisition were $753,236,069 (including $26,115,833 of net unrealized appreciation) and $754,736,092, respectively. The combined net assets of the Fund immediately following the acquisition were $1,507,972,161. For financial reporting purposes, assets received and shares issued by the Fund were recorded at fair value; however the cost basis of the investments received from RTU was carried forward to align ongoing reporting of the Fund's realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

COHEN & STEERS INFRASTRUCTURE FUND, INC.

NOTES TO FINANCIAL STATEMENTS (Unaudited)—(Continued)

Merger related expenses, which were borne by the Fund, were approximately $507,000.

Assuming the acquisition had been completed on January 1, 2010, the Fund's pro-forma results of operations for the year ended December 31, 2010, are as follows:

Net investment income	$	91,680,301
Net realized and unrealized gain		100,068,601
Net increase in net assets resulting from operations	$	191,748,902

Because the combined investment portfolios have been managed as a single integrated portfolio since the acquisition was completed, it is not practicable to separate the amounts of change in net assets attributable to RTU that have been included in the Fund's statement of operations.

Note 11. Subsequent Events

Events and transactions occurring after June 30, 2011 and through the date that the financial statements were issued, have been evaluated in the preparation of the financial statements and no additional disclosure is required.

In addition, the Fund's proxy voting record for the most recent 12-month period ended June 30 is available by August 31 of each year (i) without charge, upon request, by calling 800-330-7348 or (ii) on the SEC's Web site at http://www.sec.gov.

The Fund files its complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. The Fund's Forms N-Q are available (i) without charge, upon request by calling 800-330-7348, or (ii) on the SEC's Web site at http://www.sec.gov. In addition, the Forms N-Q may be reviewed and copied at the SEC's Public Reference Room in Washington, DC.

Please note that the distributions paid by the Fund to shareholders are subject to recharacterization for tax purposes and are taxable up to the amount of the Fund's investment company taxable income and net realized gains. Distributions in excess of the Fund's net investment company taxable income and realized gains are a return of capital distributed from the Fund's assets. To the extent this occurs, the Fund's shareholders of record will be notified of the estimated amount of capital returned to shareholders for each such distribution and this information will also be available at cohenandsteers.com. The final tax treatment of all distributions is reported to shareholders on their 1099-DIV forms, which are mailed after the close of each calendar year. Distributions of

COHEN & STEERS INFRASTRUCTURE FUND, INC.

capital decrease the Fund's total assets and, therefore, could have the effect of increasing the Fund's expense ratio. In addition, in order to make these distributions, the Fund may have to sell portfolio securities at a less than opportune time.

Notice is hereby given in accordance with Rule 23c-1 under the Investment Company Act of 1940 that the Fund may purchase, from time to time, shares of its common stock in the open market.

Change to Investment Policy

The Board of Directors approved revisions to the ratings criteria for determining whether a security is deemed investment grade or below investment grade. The determination of whether a security is deemed investment grade or below investment grade will be determined at the time of investment. A security will be considered to be investment grade if it is rated as such by one nationally recognized statistical rating organization (NRSRO) (for example minimum Baa3 or BBB- by Moody's or S&P) or, if unrated, is judged to be investment grade by the investment manager.

APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT

The Board of Directors of the Fund, including a majority of the directors who are not parties to the Fund's investment management and subadvisory agreements (the "Management Agreements"), or interested persons of any such party ("Independent Directors"), has the responsibility under the 1940 Act to approve the Fund's Management Agreements for their initial two year terms and their continuation annually thereafter at a meeting of the Board of Directors called for the purpose of voting on the approval or continuation. At a telephonic meeting held on June 14, 2011 and at a meeting held in person on June 21-22, 2011, the Management Agreements were discussed and were unanimously continued for a term ending June 30, 2012 by the Fund's Board of Directors, including the Independent Directors. The Independent Directors were represented by independent counsel who assisted them in their deliberations during the meeting and executive session.

In considering whether to continue the Management Agreements, the Board of Directors reviewed materials provided by the Fund's investment manager (the "Investment Manager") and Fund counsel which included, among other things, fee, expense and performance information compared to peer funds ("Peer Funds") and performance comparisons to a larger category universe, prepared by an independent data provider; summary information prepared by the Investment Manager; and a memorandum outlining the legal duties of the Board of Directors. The Board of Directors also spoke directly with representatives of the independent data provider and met with investment management personnel. In addition, the Board of Directors considered information provided from time to time by the Investment Manager throughout the year at meetings of the Board of Directors, including presentations by portfolio managers relating to the investment performance of the Fund and the investment strategies used in pursuing the Fund's objective. In particular, the Board of Directors considered the following:

(i) The nature, extent and quality of services provided by the Investment Manager and the Subadvisors: The Board of Directors reviewed the services that the Investment Manager and the sub-investment

COHEN & STEERS INFRASTRUCTURE FUND, INC.

advisors (the "Subadvisors") provide to the Fund, including, but not limited to, making the day-to-day investment decisions for the Fund, and, for the Investment Manager, generally managing the Fund's investments in accordance with the stated policies of the Fund. The Board of Directors also discussed with officers and portfolio managers of the Fund the types of transactions that were being done on behalf of the Fund. Additionally, the Board of Directors took into account the services provided by the Investment Manager and the Subadvisors to its other funds, including those that have investment objectives and strategies similar to the Fund. The Board of Directors next considered the education, background and experience of the Investment Manager's and Subadvisors' personnel, noting particularly that the favorable history and reputation of the portfolio managers for the Fund has had, and would likely continue to have, a favorable impact on the Fund. The Board of Directors further noted the Investment Manager's and Subadvisors' ability to attract qualified and experienced personnel. After consideration of the above factors, among others, the Board of Directors concluded that the nature, extent and quality of services provided by the Investment Manager and the Subadvisors are adequate and appropriate.

(ii) Investment performance of the Fund and the Investment Manager and Subadvisors: The Board of Directors considered the investment performance of the Fund compared to Peer Funds and compared to a relevant linked benchmark. The Board of Directors noted that for the one-, three- and five-year periods ended March 31, 2011, the Fund underperformed the Peer Funds' medians. The Board of Directors noted that the Fund outperformed its linked benchmark for the one-year period, and slightly underperformed its linked benchmark for the three- and five-year periods ended March 31, 2011. The Board of Directors engaged in discussions with the Investment Manager regarding the contributors and detractors to the Fund's performance during the periods, as well as the impact of leverage on the Fund's performance. The Board of Directors also considered supplemental information provided by the Investment Manager and Subadvisors', including a narrative summary of various factors affecting performance, and the Investment Manager's performance in managing other infrastructure funds. The Board of Directors determined to closely monitor the Fund performance and requested that the Investment Manager provide updates for this purpose.

(iii) Cost of the services provided and profits realized by the Investment Manager from the relationship with the Fund: Next, the Board of Directors considered the management fees and administrative fees payable by the Fund, as well as the Fund's expense ratio. As part of its analysis, the Board of Directors gave consideration to the fee and expense analyses provided by the independent data provider. The Board of Directors considered that the Fund's actual management fees, at managed and common asset levels are lower than the peer group medians, and contractual management fees at common asset levels were at the Peer Funds' medians. The Board of Directors also noted that the Fund's net expense ratios at managed and common asset levels, with and without investment-related expenses, were lower than the medians of the Peer Funds. The Board considered the impact leverage levels and change to the capital structure by replacing auction market preferred securities with borrowings on the Fund's fees and expenses at managed and common asset levels. The Board of Directors also noted that the Investment Manager continues to waive a portion of its management fee until early 2012 and that the Fund pays an administration fee to the Investment Manager. The Board of Directors then considered the administrative

COHEN & STEERS INFRASTRUCTURE FUND, INC.

services provided by the Investment Manager, including compliance and accounting services. The Board of Directors concluded that the Fund's current expense structure is satisfactory.

The Board of Directors also reviewed information regarding the profitability to the Investment Manager of its relationship with the Fund. The Board of Directors considered the level of the Investment Manager's profits and whether the profits were reasonable for the Investment Manager. Because the Subadvisors are paid by the Investment Manager and not by the Fund and are subsidiaries of the Investment Manager, and the Board of Directors considered the profitability of the Investment Manager as a whole, the Board of Directors did not consider the Subadvisors' separate profitability to be relevant to their considerations. The Board of Directors took into consideration other benefits to be derived by the Investment Manager in connection with the Management Agreement, noting particularly the research and related services, within the meaning of Section 28(e) of the Securities Exchange Act of 1934, as amended, that the Investment Manager receives by allocating the Fund's brokerage transactions. The Board of Directors also considered the fees received by the Investment Manager under the Administration Agreement, and noted the significant services received, such as compliance, accounting and operational services and furnishing office space and facilities for the Fund, and providing persons satisfactory to the Board of Directors to serve as officers of the Fund, and that these services were beneficial to the Fund. The Board of Directors concluded that the profits realized by the Investment Manager from its relationship with the Fund were reasonable and consistent with fiduciary duties.

(iv) The extent to which economies of scale would be realized as the Fund grows and whether fee levels would reflect such economies of scale: The Board of Directors noted that, as a closed-end fund, the Fund would not be expected to have inflows of capital that might produce increasing economies of scale. The Board of Directors determined that there were no significant economies of scale that were not being shared with shareholders.

(v) Comparison of services rendered and fees paid to those under other investment management contracts, such as contracts of the same and other investment advisers or other clients: As discussed above in (iii), the Board of Directors compared the fees paid under the Management Agreements to those under other investment management contracts of other investment advisers managing Peer Funds. The Board of Directors also considered the services rendered, fees paid and profitability under the Management Agreements to the Investment Manager's other advisory contracts with institutional and other clients with similar investment mandates, including subadvised mutual funds and proprietary funds. The Board of Directors also considered the entrepreneurial risk and financial exposure assumed by the Investment Manager in developing and managing the Fund that the Investment Manager does not have with institutional and other clients. The Board of Directors determined that on a comparative basis the fees under the Management Agreements were reasonable in relation to the services provided.

No single factor was cited as determinative to the decision of the Board of Directors. Rather, after weighing all of the considerations and conclusions discussed above, the Board of Directors, including the Independent Directors, unanimously approved the continuation of the Management Agreements.
