Rowe Price Mid-Cap Growth Fund - -------------------------------------------------------------------------------- Certified Annual Report Dear Shareholders, We are pleased to report that the Mid-Cap Growth Fund and its Advisor Class and R Class shares generated excellent returns in 2003, as shown in the table on the preceding page. Our results modestly trailed the outstanding gain of the aggressive-growth-oriented Russell Midcap Growth Index, but exceeded the returns of the broad S&P MidCap 400 Index and the Lipper Mid-Cap Growth Funds Index. (The performance of the Advisor and R Class shares was somewhat lower due to their differing cost structures.) As you know, the fund's objective is to seek long-term capital appreciation by investing in mid-cap stocks offering the potential for above-average earnings growth. [Graphic Omitted] Major Index Returns - -------------------------------------------------------------------------------- 12-Month Return S&P 500 Stock Index 29% S&P MidCap 400 Index 36% Russell 2000 Index 47% Nasdaq Composite Index 50% The Major Index Returns chart shows how various domestic market indexes performed over the fund's fiscal year. As you can see, the most aggressive indices, the small-cap Russell 2000 Index and the tech-heavy Nasdaq Composite Index, produced the most outsized returns in 2003. The broad mid-cap universe, as measured by the S&P MidCap 400 Index, also delivered strong performance, ahead of the large-cap dominated S&P 500 Stock Index. The Top 5 Sectors table shows how our weightings among the fund's top five sectors changed over the last year. The most significant changes were a reduction in our exposure to the health care sector, partly the result of profit taking in the generic drug group. We still consider health care one of the most fundamentally attractive sectors in which to invest. Top 5 Sectors - -------------------------------------------------------------------------------- Percent of Net Assets 12/31/02 12/31/03 - -------------------------------------------------------------------------------- Information Technology 21.1% 22.9% Health Care 21.3 18.1 Consumer Discretionary 15.0 15.1 Industrials and Business Services 15.5 13.7 Energy 9.1 7.9 For comparison purposes, we have restated the historical weightings to incorporate changes to the sector and industry classification system. The Best and Worst Contributors table shows the five largest contributors and detractors to the fund's performance in 2003. The largest contributors to performance were institutional pharmacy services provider Omnicare, wireless services provider Nextel Communications, discount consumer electronics leader Best Buy, Internet security software provider VeriSign, and biotechnology company Gilead Sciences. The largest detractors were weight-loss firm Weight Watchers, financial data processor BISYS Group, biotechnology company Vertex Pharmaceuticals, laboratory supplies distributor Apogent Technologies, and radio chain Westwood One.

The investigations have led to allegations that executives of several mutual fund companies permitted or engaged in improper mutual fund trading. In addition, certain intermediaries that process fund transactions are alleged to have assisted some investors in executing improper mutual fund trades. I want T. Rowe Price shareholders to know that we emphatically condemn the abuses that have been revealed or alleged against other firms in our industry. Our firm has not entered and will not enter into any agreements with any investors or intermediaries that authorize after-hours trading or excessive short-term trading in any of our funds. T. Rowe Price investors can be assured that our firm unequivocally opposes illegal or inappropriate trading of any nature and has policies and procedures in place designed to protect the best interests of our long-term shareholders. No T. Rowe Price executives or portfolio managers or investment personnel of the T. Rowe Price mutual funds have engaged in any inappropriate trading of T. Rowe Price mutual funds. You may find out more about our trading policies and the steps we take to protect your interests by visiting our Web site (troweprice.com). These policies are also spelled out in your fund's prospectus. Thank you for your continued support. Respectfully submitted, James S. Riepe Chairman January 14, 2004 T.

T. Rowe Price Mid-Cap Growth Fund - -------------------------------------------------------------------------------- Certified Annual Report December 31, 2003 Notes to Financial Statements NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price Mid-Cap Growth Fund, Inc. (the fund) is registered under the Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end management investment company. The fund seeks to provide long-term capital appreciation by investing in mid-cap stocks with potential for above-average earnings growth. The fund has three classes of shares: Mid-Cap Growth Fund (Mid-Cap Growth class), offered since June 30, 1992, Mid-Cap Growth Fund--Advisor Class (Advisor Class), offered since March 31, 2000, and Mid-Cap Growth Fund--R Class (R Class), offered since September 30, 2002. Advisor Class shares are sold only through brokers and other financial intermediaries, and R Class shares are available to retirement plans serviced by intermediaries. The Advisor Class and R Class each operate under separate Board-approved Rule 12b-1 plans, pursuant to which each class compensates financial inter-mediaries for distribution and certain administrative services. Each class has exclusive voting rights on matters related solely to that class, separate voting rights on matters that relate to all classes, and, in all other respects, the same rights and obligations as the other classes. The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of estimates made by fund management. Valuation The fund values its investments and computes its net asset value per share at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day that the NYSE is open for business. Equity securities listed or regularly traded on a securities exchange or in the over-the-counter market are valued at the last quoted sale price, or official closing price for certain markets, at the time the valuations are made. A security that is listed or traded on more than one exchange is valued at the quotation on the exchange determined to be the primary market for such security. Listed securities not traded on a particular day are valued at the mean of the latest bid and ask prices for domestic securities and the last quoted sale price for international securities. Investments in mutual funds are valued at the mutual fund's closing net asset value per share on the day of valuation. Other investments and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund's Board of Directors. Most foreign markets close before the NYSE. Normally, developments that could affect the values of securities that occur between the close of a foreign market and the close of the NYSE will not be reflected in security valuations used by the fund to compute its share price. However, if developments are so significant that they will, in the judgment of the fund, clearly and materially affect security values, such valuations may be adjusted to reflect the estimated fair value of the securities as of the close of the NYSE, as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund's Board of Directors. Currency Translation Assets, including investments, and liabilities denominated in foreign currencies are translated into U.S. dollar values each day at the prevailing exchange rate, using the mean of the bid and ask prices of such currencies against U.S. dollars as quoted by a major bank. Purchases and sales of securities, income, and expenses are translated into U.S. dollars at the prevailing exchange rate on the date of the transaction. The effect of changes in foreign currency exchange rates on realized and unrealized security gains and losses is reflected as a component of security gains and losses. Class Accounting The Advisor Class and R Class each pay distribution and administrative expenses in the form of Rule 12b-1 fees, in an amount not exceeding 0.25% and 0.50%, respectively, of the class's average daily net assets. Shareholder servicing, prospectus, and shareholder report expenses incurred by each class are charged directly to the class to which they relate. Expenses common to all classes, investment income, and realized and unrealized gains and losses are allocated to the classes based upon the relative daily net assets of each class. Income distributions, if any, are declared and paid by each class on an annual basis. Capital gain distributions, if any, are declared and paid by the fund, typically on an annual basis. Rebates and Credits Subject to best execution, the fund may direct certain security trades to brokers who have agreed to rebate a portion of the related brokerage commission to the fund in cash. Commission rebates are included in realized gain on securities in the accompanying financial statements and totaled $337,000 for the year ended December 31, 2003. Additionally, the fund earns credits on temporarily uninvested cash balances at the custodian that reduce the fund's custody charges. Custody expense in the accompanying financial statements is presented before reduction for credits, which are reflected as expenses paid indirectly. In-Kind Redemptions In certain circumstances, the fund may distribute portfolio securities rather than cash as payment for a redemption of fund shares (in-kind redemption). For financial reporting purposes, the fund recognizes a gain on in-kind redemptions to the extent the value of the distributed securities on the date of redemption exceeds the cost of those securities; the fund recognizes a loss if cost exceeds value. Gains and losses realized on in-kind redemptions are not recognized for tax purposes, and are reclassified from undistributed realized gain (loss) to paid-in capital. During the year ended December 31, 2003, the fund realized $52,741,000 of net gain on $112,246,000 of in-kind redemptions. Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions are reflected as realized gain/loss. Dividend income and capital gain distributions are recorded on the ex-dividend date. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Distributions to shareholders are recorded on the ex-dividend date. Income distributions, if any, are declared and paid on an annual basis. Capital gain distributions, if any, are typically declared and paid on an annual basis. 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 2 - INVESTMENT TRANSACTIONS Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks or enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund's prospectus and Statement of Additional Information. Affiliated Companies The fund may invest in certain securities that are considered affiliated companies. As defined by the 1940 Act, an affiliated company is one in which the fund owns 5% or more of the outstanding voting securities. At December 31, 2003, the value of affiliated companies totaled $1,014,456,000, representing 9.9% of the value of the fund's investments in securities. For the year then ended, $8,433,000 (25.7%) of dividend income, and $3,127,000 (0.8%) of net realized gain reflected in the accompanying financial statements resulted from the fund's transactions with affiliated companies. Other Purchases and sales of portfolio securities, other than short-term securities, aggregated $3,751,272,000 and $2,170,446,000, respectively, for the year ended December 31, 2003. NOTE 3 - FEDERAL INCOME TAXES No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its taxable income and gains. Federal income tax regulations differ from generally accepted accounting principles; therefore, distributions determined in accordance with tax regulations may differ significantly in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character. Financial records are not adjusted for temporary differences. There were no distributions in the year ended December 31, 2003. At December 31, 2003, the tax-basis components of net assets were as follows: - -------------------------------------------------------------------------------- Unrealized appreciation $ 2,654,666,000 Unrealized depreciation (188,791,000) Net unrealized appreciation (depreciation) 2,465,875,000 Capital loss carryforwards (258,933,000) Paid-in capital 8,013,743,000 Net assets $ 10,220,685,000 ------------------ The fund intends to retain realized gains to the extent of available capital loss carryforwards for federal income tax purposes. In 2003, the fund utilized $288,852,000 of capital loss carryforwards. As of December 31, 2003, the fund had $258,933,000 of capital loss carryforwards that expire in 2010. For the year ended December 31, 2003, the fund recorded the following permanent reclassifications to reflect tax character. Reclassifications to paid-in capital relate primarily to the current net operating loss and redemptions in kind. Results of operations and net assets were not affected by these reclassifications. - -------------------------------------------------------------------------------- Undistributed net investment income $ 33,579,000 Undistributed net realized gain (52,741,000) Paid-in capital 19,162,000 At December 31, 2003, the cost of investments for federal income tax purposes was $7,816,279,000. NOTE 4 - RELATED PARTY TRANSACTIONS The fund is managed by T. Rowe Price Associates, Inc. (the manager or Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. The investment management agreement between the fund and the manager provides for an annual investment management fee, which is computed daily and paid monthly. The fee consists of an individual fund fee, equal to 0.35 % of the fund's average daily net assets, and the fund's pro-rata share of a group fee. The group fee is calculated based on the combined net assets of certain mutual funds sponsored by Price Associates (the group) applied to a graduated fee schedule, with rates ranging from 0.48% for the first $1 billion of assets to 0.295% for assets in excess of $120 billion. The fund's portion of the group fee is determined by the ratio of its average daily net assets to those of the group. At December 31, 2003, the effective annual group fee rate was 0.32%, and investment management fee payable totaled $5,636,000. The Advisor Class and R Class are also subject to a contractual expense limitation through the limitation dates indicated in the table below. During the limitation period, the manager is required to waive its management fee and reimburse a class for any expenses, excluding interest, taxes, brokerage commissions, and extraordinary expenses, that would otherwise cause the class's ratio of total expenses to average net assets (expense ratio) to exceed its expense limitation. Through the repayment date, each class is required to repay the manager for expenses previously reimbursed and management fees waived to the extent the class's net assets have grown or expenses have declined sufficiently to allow repayment without causing the class's expense ratio to exceed its expense limitation. - -------------------------------------------------------------------------------- Advisor Class R Class Expense Limitation 1.10% 1.40% Limitation Date 12/31/03 4/30/04 Repayment Date 12/31/05 4/30/06 For the year ended December 31, 2003, each class operated below its expense limitation. In addition, the fund has entered into service agreements with Price Associates and two wholly owned subsidiaries of Price Associates (collectively, Price). Price Associates computes the daily share prices and maintains the financial records of the fund. T. Rowe Price Services, Inc., provides shareholder and administrative services in its capacity as the fund's transfer and dividend disbursing agent. T. Rowe Price Retirement Plan Services, Inc., provides subaccounting and recordkeeping services for certain retirement accounts invested in the Mid-Cap Growth class and R Class. Expenses incurred pursuant to these service agreements totaled $8,692,000 for the year ended December 31, 2003, of which $793,000 was payable at period-end. Additionally, the fund is one of several mutual funds in which certain college savings plans managed by Price Associates may invest. As approved by the fund's Board of Directors, shareholder servicing costs associated with each college savings plan are borne by the fund in proportion to the average daily value of its shares owned by the college savings plan. For the year ended December 31, 2003, the fund was charged $155,000 for shareholder servicing costs related to the college savings plans, of which $122,000 was for services provided by Price and $13,000 was payable at period-end. At December 31, 2003, approximately 0.3% of the outstanding shares of the Mid-Cap Growth class were held by college savings plans. The fund is also one of several mutual funds sponsored by Price Associates (underlying Price funds) in which the T. Rowe Price Retirement Funds (Retirement Funds) may invest. The Retirement Funds do not invest in the underlying Price funds for the purpose of exercising management or control. Pursuant to a special servicing agreement, expenses associated with the operation of the Retirement Funds are borne by each underlying Price fund to the extent of estimated savings to it and in proportion to the average daily value of its shares owned by the Retirement Funds. Expenses allocated under this agreement are reflected as shareholder servicing expense in the accompanying financial statements. For the year ended December 31, 2003, the fund was allocated $105,000 of Retirement Funds' expenses, of which $52,000 related to services provided by Price and $14,000 was payable at period-end. At December 31, 2003, approximately 0.4% of the outstanding shares of the Mid-Cap Growth class were held by the Retirement Funds. The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe Price Government Reserve Investment Fund (collectively, the Reserve Funds), open-end management investment companies managed by Price Associates. The Reserve Funds are offered as cash management options only to mutual funds, trusts, and other accounts managed by Price Associates and/or its affiliates, and are not available to the public. The Reserve Funds pay no investment management fees. During the year ended December 31, 2003, dividend income from the Reserve Funds totaled $4,975,000. T.
