The Markets in Review

Dear Shareholder,

Market volatility has remained low from a long-term perspective, but increased over the course of 2014 amid higher valuations in risk assets (such as equities and high yield bonds), geopolitical risks, uneven global economic growth and uncertainty around policy moves from the world’s largest central banks. As the U.S. Federal Reserve (the “Fed”) gradually reduced its bond buying program (which ultimately ended in October 2014), U.S. interest rates surprisingly trended lower and stock prices forged ahead despite high valuations on the back of a multi-year bull market. Geopolitical tensions intensified in Ukraine and the Middle East and oil prices became highly volatile in the middle of the summer, stoking worries about economic growth outside the United States. As the U.S. economy continued to show steady improvement, the stronger data caused concern among investors that the Fed would raise short-term rates sooner than previously anticipated. The U.S. dollar appreciated and global credit markets tightened, ultimately putting a strain on investor flows, and financial markets broadly weakened in the third quarter.

U.S. economic growth picked up considerably in the fourth quarter while the broader global economy showed signs of slowing. U.S. markets significantly outperformed international markets even as the European Central Bank (“ECB”) and the Bank of Japan eased monetary policy, which drove further strengthening in the U.S. dollar. Oil prices plummeted in the fourth quarter due to a global supply-and-demand imbalance, sparking a selloff in energy-related assets and stress in emerging markets. Fixed income investors piled into U.S. Treasuries as their persistently low yields became relatively attractive as compared to international sovereign debt.

Equity markets reversed in the first quarter of 2015 and U.S. stocks underperformed international markets, notably Europe and Japan, but also emerging markets. Investors had held high expectations for the U.S. economy, but after a harsh winter, first-quarter data disappointed and high valuations took their toll on U.S. stocks. Meanwhile, economic reports in Europe and Asia easily beat investors’ very low expectations for those economies, and accommodative policies from global central banks helped international equities rebound. The ECB’s asset purchase program (announced in January and commenced in March) was the largest in scale and effect on the markets. Overall, market volatility decreased in the first quarter as global risks abated, with a ceasefire in Ukraine and an improving outlook for Greece’s continued membership in the Eurozone.

At BlackRock, we believe investors need to think globally, extend their scope across a broad array of asset classes and be prepared to move freely as market conditions change over time. We encourage you to talk with your financial advisor and visit blackrock.com for further insight about investing in today’s markets.

Sincerely,

Rob Kapito

Fund Summary as of March 31, 2015

Investment Objective

BlackRock Capital Appreciation Fund, Inc.’s (the “Fund”) investment objective is to seek long-term growth of capital.

Portfolio Management Commentary

How did the Fund perform?

Ÿ For the six-month period ended March 31, 2015, the Fund outperformed its benchmark, the Russell 1000^® Growth Index, and the broad-market S&P 500^® Index. The following discussion of relative performance pertains to the Russell 1000^® Growth Index.

What factors influenced performance?

Ÿ Relative to the Russell 1000^® Growth Index, the Fund’s holdings in the health care sector were the largest contributors to performance, with Valeant Pharmaceuticals International Inc. and United Therapeutics Corp. having the most positive impact. Valeant Pharmaceuticals International’s shares gained early in the reporting period as the controversy surrounding its bid for Allergan, Inc. ended with news Allergan would be acquired by Actavis PLC. More recently, the company’s shares responded favorably to its plan to acquire Salix Pharmaceuticals Ltd., establishing its presence in the gastrointestinal therapeutics market. United Therapeutics’ stock price climbed after receiving a favorable ruling in its patent infringement lawsuit against competitor Sandoz. Greater appreciation for the potential of the company’s oral version of Remodulin may also have lent support to the stock price.

Ÿ Positive relative performance was also supported by favorable stock selection in the information technology (“IT”) sector. Most advantageous was the Fund’s lack of exposure to both Microsoft Corp. and International Business Machines Corp. (IBM). The Fund’s lack of exposure to Microsoft had been due to the investment advisor’s concerns around the declining profit growth from PCs and the Windows business. These concerns proved accurate early in 2015 as the company reported disappointing December quarterly results due to a larger than expected decline in its PC businesses. IBM was a significant underperformer in the first half of the reporting period as the secular pressures of cloud, mobile and infrastructure commoditization resulted in the company’s worst earnings miss in a decade. Also adding value in IT was the Fund’s position in Visa Inc., which outperformed as the company’s quarterly financial results and outlook for 2015 both exceeded expectations.

Ÿ Elsewhere, the Fund benefited from limited exposure to the energy sector, especially the energy equipment & services industry, as well as a position in athletic apparel maker lululemon athletica inc.

Ÿ Conversely, the Fund’s positioning in the industrials and consumer discretionary sectors was the prime detractor from performance. Aerospace & defense constrained relative performance within industrials, while internet & catalog retail holdings and underexposure to the strong-performing specialty retail segment had the greatest negative impact within consumer discretionary.

Ÿ The largest detractors at the individual stock level were Google Inc. and Wynn Resorts Ltd. Google shares lost ground as the company’s third-quarter results came in below expectations on both the top and bottom lines due to slowing in advertising growth and higher costs. Wynn Resorts underperformed as China’s anti-corruption campaign intensified, causing gaming revenues in Macau to fall below expectations and, in turn, leading to negative earnings revisions for the company; the position was eliminated from the Fund by the end of the reporting period.

Ÿ The Fund’s positions in Precision Castparts Corp., Baidu Inc. and VMware Inc. also detracted from relative returns.

Describe recent portfolio activity.

Ÿ Due to a combination of portfolio trading activity and market movement during the six-month period, the Fund’s weighting in the IT sector increased, most notably within the software and IT services industries. The allocation to consumer staples increased as well, mainly within beverages and food & staples retailing. The Fund’s weighting in the industrials sector decreased, largely within electrical equipment and aerospace & defense. Exposure to consumer discretionary also declined, particularly with respect to media and hotels, restaurants & leisure.

Describe portfolio positioning at period end.

Ÿ As of period end, the Fund’s largest sector overweights relative to the Russell 1000^® Growth Index were in IT, particularly the internet software & services industry, and health care, with an emphasis on the pharmaceuticals and biotechnology industries. Industrials and consumer staples were the largest underweights.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015 5

About Fund Performance

Ÿ BlackRock and Institutional Shares are not subject to any sales charge. These shares bear no ongoing distribution or service fees and are available only to certain eligible investors. Prior to June 28, 2010, BlackRock Shares performance results are those of the Institutional Shares of BlackRock Capital Appreciation Portfolio, a series of BlackRock Funds^SM (the “Predecessor Fund”). Prior to June 28, 2010, Institutional Shares performance results are those of the Institutional Shares of the Predecessor Fund restated to reflect Institutional Share fees.

Ÿ Investor A Shares are subject to a maximum initial sales charge (front-end load) of 5.25% and a service fee of 0.25% per year (but no distribution fee). Certain redemptions of these shares may be subject to a contingent deferred sales charge (“CDSC”) where no initial sales charge was paid at the time of purchase. These shares are generally available through financial intermediaries.

Ÿ Investor B Shares are subject to a maximum CDSC of 4.50% declining to 0% after six years. In addition, these shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year. These shares automatically convert to Investor A Shares after approximately eight years. (There is no initial sales charge for automatic share conversions.) All returns for periods greater than eight years reflect this conversion. These shares are only available through exchanges and distribution reinvestments by current holders and for purchase by certain employer-sponsored retirement plans.

Ÿ Investor C Shares are subject to a 1.00% CDSC if redeemed within one year of purchase. In addition, these shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year. These shares are generally available through financial intermediaries.

Ÿ Class R Shares are not subject to any sales charge. These shares are subject to a distribution fee of 0.25% per year and a service fee of

0.25% per year. These shares are available only to certain employer-sponsored retirement plans. Prior to June 28, 2010, Class R Shares performance results are those of the Institutional Shares of the Predecessor Fund (which have no distribution or service fees) restated to reflect Class R Share fees.

Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com/funds to obtain performance data current to the most recent month end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in the performance table on the previous page assume reinvestment of all distributions, if any, at net asset value (“NAV”) on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Distributions paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

Performance for the Fund for periods prior to June 28, 2010 is based on performance of the Predecessor Fund, that reorganized with the Fund on that date.

BlackRock Advisors, LLC (the “Manager”), the Fund’s investment advisor, waived and/or reimbursed a portion of the Fund’s expenses. Without such waiver and/or reimbursement, the Fund’s performance would have been lower. The Manager is under no obligation to waive or reimburse or to continue waiving or reimbursing its fees after the applicable termination date. See Note 5 of the Notes to Financial Statements for additional information on waivers and reimbursements.

6 BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015

Disclosure of Expenses

Shareholders of the Fund may incur the following charges: (a) transactional expenses, such as sales charges; and (b) operating expenses, including investment advisory fees, service and distribution fees, including 12b-1 fees, acquired fund fees and expenses and other Fund expenses. The expense example on the previous page (which is based on a hypothetical investment of $1,000 invested on October 1, 2014 and held through March 31, 2015) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds.

The expense example provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their Fund and share class under the heading entitled “Expenses Paid During the Period.”

The expense example also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in the Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in shareholder reports of other funds.

The expenses shown in the expense example are intended to highlight shareholders’ ongoing costs only and do not reflect any transactional expenses, such as sales charges, if any. Therefore, the hypothetical example is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

Derivative Financial Instruments

The Fund may invest in various derivative financial instruments. Derivative financial instruments are used to obtain exposure to a security, index and/or market without owning or taking physical custody of securities or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage. Derivative financial instruments also involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the derivative

financial instrument. The Fund’s ability to use a derivative financial instrument successfully depends on the investment advisor’s ability to predict pertinent market movements accurately, which cannot be assured. The use of derivative financial instruments may result in losses greater than if they had not been used, may limit the amount of appreciation a Fund can realize on an investment and/or may result in lower distributions paid to shareholders. The Fund’s investments in these instruments are discussed in detail in the Notes to Financial Statements.

(d) During the six months ended March 31, 2015, investments in issuers considered to be affiliates of the Fund for purposes of Section 2(a)(3) of the Investment Company Act of 1940, as amended, were as follows:

Affiliate	Shares/Beneficial Interest Held at September 30, 2014		Net Activity			Shares/Beneficial Interest Held at March 31, 2015		Income		Realized Gain
BlackRock Liquidity Funds, TempFund, Institutional Class		—		22,578,118			13,657,687	$	8,265	$	2,243
BlackRock Liquidity Series, LLC, Money Market Series	$	93,425,140	$	(8,397,822	)	$	85,027,318	$	110,119		—

The Fund may withdraw up to 25% of its investment daily, although the manager of the BlackRock Liquidity Series, LLC, Money Market Series, in its sole discretion, may permit an investor to withdraw more than 25% on any one day.

Ÿ For Fund compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by the investment advisor. These definitions may not apply for purposes of this report, which may combine such industry sub-classifications for reporting ease.

Ÿ Fair Value Measurements — Various inputs are used in determining the fair value of investments. These inputs to valuation techniques are categorized into a disclosure hierarchy consisting of three broad levels for financial statement purposes. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The categorization of a value determined for investments is based on the pricing transparency of the investment and is not necessarily an indication of the risks associated with investing in those securities. The three levels of the fair value hierarchy are as follows:

Ÿ Level 1 — unadjusted quoted prices in active markets/exchanges for identical assets or liabilities that the Fund has the ability to access

Ÿ Level 2 — other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates or other market–corroborated inputs)

Ÿ Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments)

Changes in valuation techniques may result in transfers into or out of an assigned level within the disclosure hierarchy. In accordance with the Fund’s policy, transfers between different levels of the fair value disclosure hierarchy are deemed to have occurred as of the beginning of the reporting period. For information about the Fund’s policy regarding valuation of investments, refer to Note 2 of the Notes to Financial Statements.

Schedule of Investments (concluded)

A reconciliation of Level 3 investments is presented when the Fund had a significant amount of Level 3 investments and derivative financial instruments at the beginning and/or end of the period in relation to net assets. The following table is a reconciliation of Level 3 investments for which significant unobservable inputs were used in determining fair value:

	Preferred Securities
Assets:
Opening balance, as of September 30, 2014	$	31,222,542
Transfers into Level 3		—
Transfers out of Level 3		—
Accrued discounts/premiums		—
Net realized gain (loss)		—
Net change in unrealized appreciation/depreciation1		14,057,784
Purchases		—
Sales		—
Closing balance, as of March 31, 2015	$	45,280,326
Net change in unrealized appreciation/depreciation on investments still held at March 31, 20151	$	14,057,784

¹  Any difference between Net change in unrealized appreciation/depreciation and Net change in unrealized appreciation/depreciation on investments still held at March 31, 2015 is generally due to investments no longer held or categorized as Level 3 at period end.

The following table summarizes the valuation techniques used and unobservable inputs utilized by the BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) to determine the value of certain of the Fund’s Level 3 investments as of March 31, 2015.

	Value		Valuation Techniques		Unobservable Inputs	Range of Unobservable Inputs Utilized
Assets:
Preferred Stocks2	$	45,280,326		Probability-Weighted Expected Return Model	Years to IPO3 IPO Exit Probability4 Discount Rate3 Revenue Multiple4		1.4-2.9 95.00% 21.30% 14.0x-16.0x

²  For the period ended March 31, 2015, the valuation technique for an investment classified as preferred stocks changed to a Probability-Weighted Expected Return Model. The investment was previously valued utilizing a market comparable company and option pricing model approach. A Probability-Weighted Expected Return Model was considered to be a more relevant measure of fair value for this investment which leverages the most recent equity raise pre-money valuation.

³  Decrease in unobservable input may result in a significant increase to value, while an increase in the unobservable input may result in a significant decrease to value.

⁴  Increase in unobservable input may result in a significant increase to value, while a decrease in the unobservable input may result in a significant decrease to value.

BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015 21

Notes to Financial Statements (Unaudited)

1. Organization:

BlackRock Capital Appreciation Fund, Inc. (the “Fund”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, open-end management investment company. The Fund is organized as a Maryland corporation.

The Fund offers multiple classes of shares. All classes of shares have identical voting, dividend, liquidation and other rights and are subject to the same terms and conditions, except that certain classes bear expenses related to the shareholder servicing and distribution of such shares. Institutional Shares are sold only to certain eligible investors. Investor B Shares are only available through exchanges and distribution reinvestments by current holders and for purchase by certain employer-sponsored retirement plans. Class R Shares are available only to certain employer-sponsored retirement plans. Investor A and Investor C Shares are generally available through financial intermediaries. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B shareholders may vote on material changes to the Investor A distribution and service plan).

Share Class	Initial Sales Charge	CDSC	Conversion Privilege
BlackRock, Institutional, and Class R Shares	No	No	None
Investor A Shares	Yes	No1	None
Investor B Shares	No	Yes	To Investor A Shares after approximately 8 years
Investor C Shares	No	Yes	None

¹  Investor A Shares may be subject to a CDSC where no initial sales charge was paid at the time of purchase.

The Fund, together with certain other registered investment companies advised by BlackRock Advisors, LLC (the “Manager”) or its affiliates, is included in a complex of open-end funds referred to as the Equity-Bond Complex.

2. Significant Accounting Policies:

The Fund’s financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following is a summary of significant accounting policies followed by the Fund:

Valuation: The Fund’s investments are valued at fair value as of the close of trading on the New York Stock Exchange (“NYSE”) (generally 4:00 p.m., Eastern time). U.S. GAAP defines fair value as the price the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Fund determines the fair values of its financial instruments at market value using independent dealers or pricing services under policies approved by the Board of Directors of the Fund (the “Board”). The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to provide oversight of the pricing function for the Fund for all financial instruments.

Equity investments traded on a recognized securities exchange are valued at the official close price each day, if available. For equity investments traded on more than one exchange, the official close price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange for which there were no sales on that day may be valued at the last available bid (long positions) or ask (short positions) price. Investments in open-end registered investment companies are valued at NAV each business day.

Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates determined as of the close of business on the NYSE. Forward foreign currency exchange contracts are valued at the mean between the bid and ask prices and are determined as of the close of business on the NYSE. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available.

The Fund values its investment in BlackRock Liquidity Series, LLC, Money Market Series (the “Money Market Series”) at fair value, which is ordinarily based upon its pro rata ownership in the underlying fund’s net assets. The Money Market Series seeks current income consistent with maintaining liquidity and preserving capital. Although the Money Market Series is not registered under the 1940 Act, its investments will follow the parameters of investments by a money market fund that is subject to Rule 2a-7 under the 1940 Act. The Fund may withdraw up to 25% of its investment daily, although the Manager of the Money Market Series, in its sole discretion, may permit an investor to withdraw more than 25% on any one day.

22 BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015

Notes to Financial Statements (continued)

In the event that the application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, or its delegate, in accordance with a policy approved by the Board as reflecting fair value (“Fair Value Investments”). When determining the price for Fair Value Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that the Fund might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the Global Valuation Committee, or its delegate, deems relevant consistent with the principles of fair value measurement, which include the market approach, income approach and/or in the case of recent investments, the cost approach, as appropriate. The market approach generally consists of using comparable market transactions. The income approach generally is used to discount future cash flows to present value and is adjusted for liquidity as appropriate. These factors include but are not limited to: (i) attributes specific to the investment or asset; (ii) the principal market for the investment or asset; (iii) the customary participants in the principal market for the investment or asset; (iv) data assumptions by market participants for the investment or asset, if reasonably available; (v) quoted prices for similar investments or assets in active markets; and (vi) other factors, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, recovery rates, liquidation amounts and/or default rates. Due to the inherent uncertainty of valuations of such investments, the fair values may differ from the values that would have been used had an active market existed. The Global Valuation Committee, or its delegate, employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Fund’s pricing vendors, regular reviews of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices and large movements in market values and reviews of any market related activity. The pricing of all Fair Value Investments is subsequently reported to the Board or a committee thereof on a quarterly basis.

Generally, trading in foreign instruments is substantially completed each day at various times prior to the close of business on the NYSE. Occasionally, events affecting the values of such instruments may occur between the foreign market close and the close of business on the NYSE that may not be reflected in the computation of the Fund’s net assets. If events (e.g., a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such instruments, those instruments may be Fair Value Investments and be valued at their fair value, as determined in good faith by the Global Valuation Committee, or its delegate, using a pricing service and/or policies approved by the Board. Each business day, the Fund uses a pricing service to assist with the valuation of certain foreign exchange-traded equity securities and foreign exchange-traded and over-the-counter (“OTC”) options (the “Systematic Fair Value Price”). Using current market factors, the Systematic Fair Value Price is designed to value such foreign securities and foreign options at fair value as of the close of business on the NYSE, which follows the close of the local markets.

Foreign Currency: The Fund’s books and records are maintained in U.S. dollars. Purchases and sales of investment securities are recorded at the rates of exchange prevailing on the respective dates of such transactions. Generally, when the U.S. dollar rises in value against a foreign currency, the Fund’s investments denominated in that currency will lose value because that currency is worth fewer U.S. dollars; the opposite effect occurs if the U.S. dollar falls in relative value.

The Fund does not isolate the 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 investments held or sold for financial reporting purposes. Accordingly, the effects of changes in foreign currency exchange rates on investments are not segregated in the Statement of Operations from the effects of changes in market prices of those investments, but are included as a component of net realized and unrealized gain (loss) from investments. The Fund reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for federal income tax purposes.

Segregation and Collateralization: In cases where the Fund enters into certain investments (e.g., forward foreign currency exchange contracts), that would be “senior securities” for 1940 Act purposes, the Fund may segregate or designate on its books and records cash or liquid securities having a market value at least equal to the amount of the Fund’s future obligations under such investments. Doing so allows the investment to be excluded from treatment as a “senior security.” Furthermore, if required by an exchange or counterparty agreement, the Fund may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments or obligations.

Investment Transactions and Investment Income: For financial reporting purposes, investment transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend date. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Fund is informed of the ex-dividend date. Under the applicable foreign tax laws, a withholding tax at various rates may be imposed on capital gains, dividends and interest. Upon notification from issuers, some of the dividend income received from a real estate investment trust may be redesignated

BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015 23

Notes to Financial Statements (continued)

as a reduction of cost of the related investment and/or realized gain. Income, expenses and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets.

Distributions: Distributions paid by the Fund are recorded on the ex-dividend date. The character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Recent Accounting Standard: In June 2014, the Financial Accounting Standards Board issued guidance to improve the financial reporting of reverse repurchase agreements and other similar transactions. The guidance will require expanded disclosure for entities that enter into reverse repurchase agreements and similar transactions accounted for as secured borrowings. It is effective for financial statements with fiscal years beginning on or after December 15, 2014 and for interim periods beginning after March 15, 2015. Management is evaluating the impact, if any, of this guidance on the Fund’s financial statement disclosures.

Other: Expenses directly related to the Fund or its classes are charged to the Fund or the applicable class. Other operating expenses shared by several funds are prorated among those funds on the basis of relative net assets or other appropriate methods. Expenses directly related to the Fund and other shared expenses prorated to the Fund are allocated daily to each class based on its relative net assets or other appropriate methods.

The Fund has an arrangement with the custodian whereby fees may be reduced by credits earned on uninvested cash balances, which, if applicable, are shown as fees paid indirectly in the Statement of Operations. The custodian imposes fees on overdrawn cash balances, which can be offset by accumulated credits earned or may result in additional custody charges.

3. Securities and Other Investments:

Preferred Stock: The Fund may invest in preferred stock. Preferred stock has a preference over common stock in liquidation (and generally in receiving dividends as well) but is subordinated to the liabilities of the issuer in all respects. As a general rule, the market value of preferred stock with a fixed dividend rate and no conversion element varies inversely with interest rates and perceived credit risk, while the market price of convertible preferred stock generally also reflects some element of conversion value. Because preferred stock is junior to debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred stock than in a more senior debt security with similar stated yield characteristics. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Securities Lending: The Fund may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. Government. The initial collateral received by the Fund is required to have a value of at least 102% of the current value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current market value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Fund and any additional required collateral is delivered to the Fund on the next business day. During the term of the loan, the Fund is entitled to all distributions made on or in respect of the loaned securities. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

The market value of securities on loan and the value of the related collateral are shown separately in the Statement of Assets and Liabilities as a component of investments at value — unaffiliated, and collateral on securities loaned at value, respectively. As of March 31, 2015, any securities on loan were collateralized by cash. The cash collateral invested by the securities lending agent, BlackRock Investment Management, LLC (“BIM”), if any, is disclosed in the Schedule of Investments.

Securities lending transactions are entered into by the Fund under Master Securities Lending Agreements (each, an “MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency), for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, the borrower can resell or re-pledge the loaned securities, and the Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

24 BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015

Notes to Financial Statements (continued)

As of March 31, 2015, the following table is a summary of the Fund’s securities lending agreements by counterparty, which are subject to offset under an MSLA:

Counterparty	Securities Loaned at Value		Cash Collateral Received1			Net Amount
Deutsche Bank Securities Inc.	$	16,295,108	$	(16,295,108	)		—
Goldman Sachs & Co.		11,347,900		(11,347,900	)		—
J.P. Morgan Securities LLC		31,880,920		(31,880,920	)		—
UBS Securities LLC		22,962,349		(22,962,349	)		—
Total	$	82,486,277	$	(82,486,277	)		—

¹  Collateral with a value of $85,027,318 has been received in connection with securities lending agreements. Collateral received in excess of the value of securities loaned from the individual counterparty is not shown for financial reporting purposes.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Fund benefits from a borrower default indemnity provided by BIM. BIM’s indemnity allows for full replacement of the securities loaned if the collateral received does not cover the value on the securities loaned in the event of borrower default. The Fund could suffer a loss if the value of an investment purchased with cash collateral falls below the market value of loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received.

4. Derivative Financial Instruments:

The Fund engages in various portfolio investment strategies using derivative contracts both to increase the returns of the Fund and/or to economically manage their exposure to certain risks such as foreign currency exchange rate risk. These contracts may be transacted on an exchange or OTC.

Forward Foreign Currency Exchange Contracts: The Fund enters into forward foreign currency exchange contracts as an economic hedge against either specific transactions or portfolio instruments or to obtain exposure to, or hedge exposure away from, foreign currencies (foreign currency exchange rate risk). A forward foreign currency exchange contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. Forward foreign currency exchange contracts, when used by the Fund, help to manage the overall exposure to the currencies in which some of the investments held by the Fund are denominated. The contract is marked-to-market daily and the change in market value is recorded by the Fund as an unrealized gain or loss. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. The use of forward foreign currency exchange contracts involves the risk that the value of a forward foreign currency exchange contract changes unfavorably due to movements in the value of the referenced foreign currencies.

The following is a summary of the Fund’s derivative financial instruments categorized by risk exposure:

The Effect of Derivative Financial Instruments in the Statement of Operations Six Months Ended March 31, 2015
	Net Realized Gain From	Net Change in Unrealized Appreciation/Depreciation on
Foreign currency exchange contracts:
Foreign currency transactions/translations	$151,587	$(895,412)

For the six months ended March 31, 2015, the average quarterly balances of outstanding derivative financial instruments were as follows:

Forward foreign currency exchange contracts:
Average amounts sold — in USD	$	20,747,364	1

¹  Actual amounts for the period are shown due to limited outstanding derivative financial instruments as of each quarter.

Counterparty Credit Risk: A derivative contract may suffer a mark-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract.

A Fund’s risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain less the value of any collateral held by such Fund.

BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015 25

Notes to Financial Statements (continued)

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with its counterparties. An ISDA Master Agreement is a bilateral agreement between each Fund and a counterparty that governs certain OTC derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, each Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. Bankruptcy or insolvency laws of a particular jurisdiction may restrictor prohibit the right of offset in bankruptcy, insolvency or other events. In addition, certain ISDA Master Agreements allow counterparties to terminate derivative contracts prior to maturity in the event the Fund’s net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA Master Agreements, which would cause the Fund to accelerate payment of any net liability owed to the counterparty.

Collateral Requirements: For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark-to-market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Fund and the counterparty.

Cash collateral that has been pledged to cover obligations of the Fund and cash collateral received from the counterparty, if any, is reported separately on the Statement of Assets and Liabilities as cash pledged as collateral and cash received as collateral, respectively. Non-cash collateral pledged by the Fund, if any, is noted in the Schedule of Investments. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (typically either $250,000 or $500,000) before a transfer is required, which is determined at the close of business of the Fund. Any additional required collateral is delivered to/pledged by the Fund on the next business day. Typically, the Fund and counterparties are not permitted to sell, re-pledge or use the collateral they receive. To the extent amounts due to the Fund from its counterparties are not fully collateralized, the Fund bears the risk of loss from counterparty non-performance. Likewise, to the extent the Fund has delivered collateral to a counterparty and stands ready to perform under the terms of its agreement with such counterparty, the Fund bears the risk of loss from a counterparty in the amount of the value of the collateral in the event the counterparty fails to return such collateral.

5. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. is the largest stockholder and an affiliate of BlackRock, Inc. (“BlackRock”) for 1940 Act purposes.

The Fund entered into an Investment Advisory Agreement with the Manager, the Fund’s investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services. The Manager is responsible for the management of the Fund’s portfolio and provides the necessary personnel, facilities, equipment and certain other services to the operations of the Fund. For such services, the Fund pays the Manager a monthly fee based on a percentage of the Fund’s average daily net assets at the following annual rates:

Average Daily Net Assets	Investment Advisory Fee
First $1 Billion		0.650	%
$1 Billion - $1.5 Billion		0.625	%
$1.5 Billion - $5 Billion		0.600	%
$5 Billion - $7.5 Billion		0.575	%
Greater than $7.5 Billion		0.550	%

The Manager voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees the Fund pays to the Manager indirectly through its investment in affiliated money market funds. However, the Manager does not waive its investment advisory fees by the amount of investment advisory fees paid in connection with the Fund’s investment in other affiliated investment companies, if any. This amount is shown as fees waived by the Manager in the Statement of Operations.

The Fund entered into a Distribution Agreement and a Distribution and Service Plan with BlackRock Investments, LLC (“BRIL”), an affiliate of the Manager. Pursuant to the Distribution and Service Plan and in accordance with Rule 12b-1 under the 1940 Act, the Fund pays BRIL ongoing service and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the relevant share class of the Fund as follows:

	Service Fee			Distribution Fee
Investor A		0.25	%		—
Investor B		0.25	%		0.75	%
Investor C		0.25	%		0.75	%
Class R		0.25	%		0.25	%

26 BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015

Notes to Financial Statements (continued)

Pursuant to sub-agreements with BRIL, broker-dealers and BRIL provide shareholder servicing and distribution services to the Fund. The ongoing service and/or distribution fee compensates BRIL and each broker-dealer for providing shareholder servicing and/or distribution related services to Investor A, Investor B, Investor C and Class R shareholders.

Pursuant to written agreements, certain financial intermediaries, some of which may be affiliates, provide the Fund with sub-accounting, recordkeeping, sub-transfer agency and other administrative services with respect to sub-accounts they service. For these services, these entities receive an asset-based fee or an annual fee per shareholder account, which will vary depending on share class and/or net assets. For the six months ended March 31, 2015, the Fund paid $78,031 to the affiliates of BlackRock in return for these services, which is included in transfer agent — class specific in the Statement of Operations.

The Manager maintains a call center, which is responsible for providing certain shareholder services to the Fund, such as responding to shareholder inquiries and processing transactions based upon instructions from shareholders with respect to the subscription and redemption of Fund shares. For the six months ended March 31, 2015, the Fund reimbursed the Manager the following amounts for costs incurred in running the call center, which are included in transfer agent — class specific in the Statement of Operations:

BlackRock	$	1,769
Institutional		1,822
Investor A		38,794
Investor B		1,462
Investor C		5,272
Class R		243
Total	$	49,362

The Manager contractually agreed to waive and/or reimburse fees or expenses in order to limit expenses, excluding interest expense, dividend expense, tax expense, acquired fund fees and expenses and certain other fund expenses, which constitute extraordinary expenses not incurred in the ordinary course of the Fund’s business. The expense limitations as a percentage of average daily net assets are as follows:

BlackRock	0.72	%
Investor C	1.94	%

The Manager has agreed not to reduce or discontinue this contractual waiver or reimbursement prior to February 1, 2025 unless approved by the Board, including a majority of the Independent Directors. On February 1 of each year, the waiver will renew automatically, so that the agreement will have a perpetual ten-year term. These amounts waived or reimbursed are shown as transfer agent fees waived — BlackRock and transfer agent fees reimbursed — BlackRock, respectively, in the Statement of Operations.

For the six months ended March 31, 2015, affiliates earned underwriting discounts, direct commissions and dealer concessions on sales of the Fund’s Investor A Shares of $56,340.

For the six months ended March 31, 2015, affiliates received CDSCs relating to transactions in Investor A, Investor B, and Investor C Shares of $3,749, $446 and $20,917, respectively.

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BIM, an affiliate of the Manager, to serve as securities lending agent for the Fund, subject to applicable conditions. As securities lending agent, BIM bears all operational costs directly related to securities lending. The Fund is responsible for expenses in connection with the investment of cash collateral received for securities on loan (the “collateral investment expenses”). The cash collateral is invested in a private investment company managed by the Manager or its affiliates. However, BIM has agreed to cap the collateral investment expenses of the private investment company to an annual rate of 0.04%. The investment advisor to the private investment company will not charge any advisory fees with respect to shares purchased by the Fund.

Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment expenses. The Fund retains a portion of securities lending income and remits a remaining portion to BIM as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement effective January 1, 2015, the Fund retains 71.5% of securities lending income, and this amount retained can never be less than 65% of the total of securities lending income plus the collateral investment expenses.

BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015 27

Notes to Financial Statements (continued)

In addition, commencing the business day following the date that the aggregate securities lending income earned across the Equity-Bond Complex in a calendar year exceeds a specified threshold, the Fund, pursuant to the securities lending agreement, will retain for the remainder of that calendar year securities lending income as follows:

75% of securities lending income, and this amount retained can never be less than 65% of the total of securities lending income plus the collateral investment expenses.

For the period February 1, 2014 through December 31, 2014, the Fund retained 70% (75% commencing on the business day following the date that the aggregate securities lending income earned across the Equity-Bond Complex in the calendar year 2014 exceeded a specified threshold and for the remainder of that calendar year) of securities lending income, and this amount retained could never be less than 65% of the total securities lending income plus the collateral investment expenses.

The share of securities lending income earned by the Fund is shown as securities lending — affiliated — net in the Statement of Operations. For the six months ended March 31, 2015, the Fund paid BIM $34,900 for securities lending agent services.

Certain officers and/or directors of the Fund are officers and/or directors of BlackRock or its affiliates. The Fund reimburses the Manager for a portion of the compensation paid to the Fund’s Chief Compliance Officer, which is included in officer and directors in the Statement of Operations.

The Fund may purchase securities from, or sell securities to, an affiliated fund provided the affiliation is due solely to having a common investment advisor, common officers, or common trustees. For the six months ended March 31, 2015, the sale transactions with an affiliated fund in compliance with Rule 17a-7 under the 1940 Act were $5,520,977.

6. Purchases and Sales:

For the six months ended March 31, 2015, purchases and sales of investments, excluding short-term securities, were $1,620,709,242 and $2,012,085,276, respectively.

7. Income Tax Information:

It is the Fund’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required.

The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s U.S. federal tax returns remains open for each of the four years ended September 30, 2014. The statutes of limitations on the Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to the Fund as of March 31, 2015, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

As of March 31, 2015, gross unrealized appreciation and depreciation based on cost for federal income tax purposes were as follows:

Tax cost	$	2,943,082,834
Gross unrealized appreciation	$	840,074,100
Gross unrealized depreciation		(10,211,409	)
Net unrealized appreciation	$	829,862,691

8. Bank Borrowings:

The Fund, along with certain other funds managed by the Manager and its affiliates (“Participating Funds”), was a party to a 364-day, $1.1 billion credit agreement with a group of lenders, under which the Fund may borrow to fund shareholder redemptions. Excluding commitments designated for a certain individual fund, the Participating Funds, including the Fund, could borrow up to an aggregate commitment amount of $650 million, subject to asset coverage and other limitations as specified in the agreement. Effective November 25, 2014, the credit agreement was amended to an aggregate commitment amount of $2.1 billion, of which the Participating Funds, including the Fund, can borrow up to $1.6 billion at any time outstanding, subject to asset coverage and other limitations as specified in the agreement. The agreement terminates on April 23, 2015, unless otherwise extended to November 24, 2015 or renewed for a period of 364 days from April 23, 2015. The amended agreement has the following terms: a fee of 0.06% per annum on unused commitment amounts and interest at a rate equal to the higher of (a) one-month LIBOR (but, in any event, not less than 0.00%) on the date the loan is made plus 0.80% per annum or (b) the Fed Funds rate (but, in any event, not less than 0.00%) in effect from time to time plus

28 BLACKROCK CAPITAL APPRECIATION FUND, INC. MARCH 31, 2015

Notes to Financial Statements (continued)

0.80% per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are included in miscellaneous expenses in the Statement of Operations, and along with commitment fees, were allocated among such funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. During the six months ended March 31, 2015, the Fund did not borrow under the credit agreement.

9. Principal Risks:

In the normal course of business, the Fund invests in securities and enters into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations (issuer credit risk). The value of securities held by the Fund may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Fund; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency, interest rate and price fluctuations. Similar to issuer credit risk, the Fund may be exposed to counterparty credit risk, or the risk that an entity with which the Fund has unsettled or open transactions may fail to or be unable to perform on its commitments. The Fund manages counterparty credit risk by entering into transactions only with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Fund to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Fund’s exposure to market, issuer and counterparty credit risks with respect to these financial assets is generally approximated by their value recorded in the Statement of Assets and Liabilities, less any collateral held by the Fund.

As of March 31, 2015, the Fund invested a significant portion of its assets in securities in the information technology, health care, and consumer discretionary sectors. Changes in economic conditions affecting such sectors would have a greater impact on the Fund and could affect the value, income and/or liquidity of positions in such securities.

10. Capital Share Transactions:
