ROWE PRICE DIVERSIFIED MID-CAP GROWTH FUND - -------------------------------------------------------------------------------- Fellow Shareholders Mid-cap growth stocks rose in the second half of 2004, as the broader market completed its second consecutive year of gains. Equities declined through mid-August as economic growth moderated amid rising short-term interest rates, surging energy costs, and a heated presidential campaign. Stock prices rose as oil prices moderated from their late-October peak of $55 per barrel, and gains accelerated following the reelection of President Bush. PERFORMANCE COMPARISON - -------------------------------------------------------------------------------- Periods Ended 12/31/04 6 Months 12 Months - -------------------------------------------------------------------------------- Diversified Mid-Cap Growth Fund 7.06% 13.70% Russell Midcap Growth Index 9.01 15.48 Lipper Mid-Cap Growth Funds Index 8.31 14.03 Your fund returned 7.06% in the second half of 2004 and 13.70% for the entire year. As shown in the table, the fund lagged its Russell and Lipper benchmarks in both periods. Our emphasis on better businesses was not rewarded. During the fourth quarter, investors exhibited risk-seeking behavior, and stocks with greater volatility had strong relative performance. During 2004, the energy and materials sectors dominated all others as commodity prices spiked. We are underweighted in the energy and materials sectors. Moreover, our investments are in companies that use commodities and add significant value to them. Based on our emphasis on higher return on invested capital and more differentiated businesses, we expect to have better relative performance during periods of market stress. MARKET ENVIRONMENT The economy continued to expand in the second half of 2004, overcoming a mid-year period of softness that was largely attributable to heightened consumer and business caution amid rising oil prices and a tight presidential election race. Both of these concerns eased in the fourth quarter, as the price of oil fell sharply from its recent high and investors welcomed the reelection of President Bush. The Federal Reserve continued to unwind its highly accommodative monetary policy in the last six months, though this was not to the detriment of the equity market. Beginning on June 30, the central bank raised the federal funds target rate gradually from 1.00% to 2.25% in five quarter-point increments. Mid-cap shares outperformed their larger counterparts in 2004. In the last six months, the S&P MidCap 400 Index and the Russell Midcap Index returned 9.80% and 12.70%, respectively, versus 7.19% for the S&P 500 Index. For the full year, the S&P MidCap 400 Index and the Russell Midcap Index returned 16.48% and 20.22%, respectively, versus 10.88% for the S&P 500 Index. As measured by various Russell indexes, growth stocks lagged value across all market capitalizations, including the mid-cap space, in both periods. Moreover, growth stocks have materially lagged for several years. We believe it is reasonable to expect mean reversion and better relative performance from the growth style in the years ahead. MID-CAP STOCK RETURNS - -------------------------------------------------------------------------------- Periods Ended 12/31/04 6 Months 12 Months - -------------------------------------------------------------------------------- Russell Midcap Index 12.70% 20.22% Russell Midcap Growth Index 9.01 15.48 Russell Midcap Value Index 15.43 23.71 Most major mid-cap growth sectors produced gains in the second half of 2004, adding to favorable performance in the first half of our fiscal year. Consumer discretionary stocks performed very well, led by shares of hotels, restaurants, and companies associated with leisure activities. Homebuilders in the household durables industry also fared well, but retailers and media stocks lagged somewhat. In the financials sector, asset managers and other companies with close ties to the capital markets produced brisk gains; insurers and commercial banks trailed. Information technology stocks generally produced good returns, but weakness among semiconductor stocks eroded strength in software and IT services companies. In the health care sector, providers and service companies greatly surpassed other underlying industries. The industrials and business services sector rose broadly, except for commercial services and supply companies. INVESTMENT STRATEGY Before discussing the portfolio's performance in detail, we would like to welcome all new shareholders to the fund--which just completed its first full year of operations--and review the investment strategy and principles that guide our management of the portfolio. o The fund invests in mid-cap stocks of companies whose earnings are expected to grow at an above-average rate. We define mid-cap companies as those whose market capitalization falls within the range of either the S&P MidCap 400 Index or the Russell Midcap Growth Index. o The fund will be fully invested because we believe that successful market timing is nearly impossible and that the costs associated with frequent trading reduce the likelihood of outperforming the market. We will not spend undue time worrying about short-term performance or trying to forecast the direction of the market. That allows us to focus on finding mid-cap companies that have the best long-term growth potential. o Unlike other mid-cap growth portfolios that are highly concentrated, the Diversified Mid-Cap Growth Fund will typically invest in approximately 300 stocks. This high degree of diversification helps to reduce the downside risk attributable to any single poorly performing security. It is notable that we are investing in companies that are early in their life cycles, and it is inevitable that some will not be as successful as we hope. Accordingly, we balance risk with potential returns. o We may purchase some larger and smaller companies that have qualities consistent with the portfolio's core characteristics, and we will not automatically sell or cease to purchase a stock of a company that the fund already owns just because the company's market capitalization exceeds the mid-cap range. o Stock selection is based on a combination of fundamental, bottom-up analysis and top-down quantitative strategies in an effort to identify companies with superior long-term appreciation prospects. We use a growth approach, looking for companies with a demonstrated ability to increase revenues, earnings, and cash flow consistently; capable management; attractive business niches; and a sustainable competitive advantage. We favor companies with above-average earnings growth and lower earnings variability. o Valuations are also important: we look for the best relative values among companies with the strongest businesses and managements. o We use a number of proprietary quantitative models to identify and evaluate the characteristics of mid-cap growth companies and the entire portfolio. PORTFOLIO REVIEW The fund is structured much like the Russell Midcap Growth Index, as indicated by the Portfolio Characteristics table. The investment-weighted median market capitalization, average company yield, and projected earnings growth rate of our holdings are about the same, while the portfolio's forward price/earnings (P/E) ratio is slightly higher than that of the index. The fund's return on equity (ROE), which measures how effectively and efficiently a company and its management are using stockholder investments, is slightly lower than that of the index but still fairly high. We believe that companies with high and sustainable profitability are good long-term investments.

Forecast data are for illustrative purposes only and are not intended to represent future investment returns. Our sector allocations are somewhat similar to those of the index. Our largest investments are in the information technology, consumer discretionary, and health care sectors. Financials and industrials and business services companies represent lesser amounts, and we have very little exposure to energy, consumer staples, materials, and telecommunication services stocks. In the information technology sector (28.2% of assets as of December 31, 2004), our focus on better businesses is the primary driver behind our overweights in semiconductor, software, and IT services companies. Business capital spending is improving due to the growing economy, and since technology represents a large portion of capital expenditures, we believe these companies will benefit. We maintain more of a tilt toward semiconductor companies with quality business models, and the stocks are reasonably valued. Unfortunately, our bias toward more differentiated chip stocks, such as Analog Devices and Xilinx, weighed on the fund's relative performance in the last six months, as more volatile semiconductor names outperformed during the fourth-quarter tech rally. In 2004, semiconductors were among the worst performing industries. We believe that the industry will shortly resolve its inventory issues and do well in 2005. (Please refer to our portfolio of investments for a complete listing of fund holdings and the amount each represents in the portfolio.) In the consumer discretionary sector (21.7% of assets), media is our largest overweight. We are broadly diversified into newspaper, radio, and advertising companies, all of which generate exceptional cash flow and have strong franchises. Our investment thesis in media is predicated on a recovery in advertising spending, which has been slower than expected. As a result, our overweight in names like Cox Radio hindered our performance. We are maintaining our media positions because the industry is attractively valued, in our opinion, and marketing spending has good long-term growth prospects. Our investments in the health care sector (19.0% of assets) are centered on services companies, medical devices, and a diversified approach to biotechnology. In our view, the health care providers and services industry represents the best risk/reward tradeoff within the sector, as valuations are reasonable, balance sheets are in good shape, and earnings trends are positive. In the last six months, our positioning in services companies such as WellChoice, Caremark RX, and WellPoint was the key driver behind our favorable relative performance in the sector. SECTOR DIVERSIFICATION - -------------------------------------------------------------------------------- Percent of Percent of Net Assets Net Assets 6/30/04 12/31/04 - -------------------------------------------------------------------------------- Information Technology 28.6% 28.2% Consumer Discretionary 20.8 21.7 Health Care 20.4 19.0 Financials 11.5 13.6 Industrials and Business Services 10.9 10.5 Energy 2.8 3.0 Consumer Staples 1.8 1.7 Materials 1.7 1.5 Telecommunication Services 1.1 0.9 Utilities 0.0 0.0 Other and Reserves 0.4 -0.1 - -------------------------------------------------------------------------------- Total 100.0% 100.0% Historical weightings reflect current industry/sector classifications. The financials sector (13.6% of assets) is our largest overweight relative to the Russell Midcap Growth Index. We favor companies tied to the capital markets--specifically trust banks and asset managers--because we believe they offer the best risk/reward tradeoff in the mid-cap growth universe. Trust banks have a more stable, fee-based revenue model and are more differentiated than spread-lending focused banks. In the last six months, we continued to add to our existing overweights in Northern Trust and Mellon Financial and established a new position in State Street. An improving economy has benefited fundamentals of companies in the industrials and business services sector (10.5% of assets). In the last six months, good relative performance in the sector stemmed from our home building and logistics holdings combined with an underweight in airlines. We are underweighting traditional industrials due to expensive valuations. Our business services holdings are broadly diversified among commercial services, logistics, and education companies. Logistics companies, such as C.H. Robinson and UTi Worldwide, are benefiting from the globalization of trade. For-profit educators exemplify our investment philosophy with sustainable business models, good management teams, visible revenue and earnings growth, and strong earnings trends, particularly in the case of Apollo Group. Other sectors have reduced representation in the mid-cap growth universe, but they are also an important part of our investment strategy. For example, in the consumer staples sector (1.7% of assets), we are positioned in high-quality firms that are able to grow earnings consistently, such as confectionary companies. The business is highly attractive, in our opinion, but valuations are fair. We maintain positions in Wrigley and Hershey Foods. In fact, Wrigley was one of our largest relative contributors during the second half of the year. In contrast, our lack of exposure to metals and mining companies in the materials sector (1.5% of assets) weighed on our relative performance. We are focused on companies that improve upon the underlying commodity, such as paint and coatings producer Valspar and specialty packing company Sealed Air. OUTLOOK The market environment in 2004 was challenging for our investment strategy, given the leadership by commodity-producing companies in the materials and energy sectors. Our style, which takes a broadly diversified approach and is consistent in buying more differentiated businesses, should do well relative to the benchmark in periods when companies with consistent earnings growth are rewarded. We believe that the market is beginning to focus more on such companies. Our fully invested approach, which balances potential rewards with assumed risk, focuses on strong businesses and management with a long-term orientation. We believe our sector and individual stock weightings will help our relative performance as we move deeper into the economic recovery. Respectfully submitted, Donald J.

The market as a whole can decline for many reasons, including adverse political or economic developments here or abroad, changes in investor psychology, or heavy institutional selling. The prospects for an industry or company may deteriorate because of a variety of factors, including disappointing earnings or changes in the competitive environment. In addition, our assessment of companies held in the fund may prove incorrect, resulting in losses or poor performance even in a rising market. Finally, the fund's investment approach could fall out of favor with the investing public, resulting in lagging performance versus other types of stock funds. The stocks of mid-cap companies entail greater risk and are usually more volatile than the shares of large companies. In addition, growth stocks can be volatile for several reasons. Since they usually reinvest a high proportion of earnings in their own businesses, they may lack the dividends usually associated with value stocks that can cushion their decline in a falling market. Also, since investors buy these stocks because of their expected superior earnings growth, earnings disappointments often result in sharp price declines. - -------------------------------------------------------------------------------- GLOSSARY Fed funds target rate: An overnight lending rate set by the Federal Reserve and used by banks to meet reserve requirements.

Returns do not reflect taxes that the shareholder may pay on fund distributions or the redemption of fund shares. When assessing performance, investors should consider both short- and long-term returns. T. ROWE PRICE DIVERSIFIED MID-CAP GROWTH FUND - -------------------------------------------------------------------------------- FUND EXPENSE EXAMPLE - -------------------------------------------------------------------------------- As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs such as redemption fees or sales loads and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period. Actual Expenses The first line of the following table ("Actual") provides information about actual account values and actual expenses. You may use the information in this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Hypothetical Example for Comparison Purposes The information on the second line of the table ("Hypothetical") is based on hypothetical account values and expenses derived from the fund's actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund's actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. Note: T. Rowe Price charges an annual small-account maintenance fee of $10, generally for accounts with less than $2,000 ($500 for UGMA/UTMA). The fee is waived for any investor whose T. Rowe Price mutual fund accounts total $25,000 or more, accounts employing automatic investing, and IRAs and other retirement plan accounts that utilize a prototype plan sponsored by T. Rowe Price (although a separate custodial or administrative fee may apply to such accounts). This fee is not included in the accompanying table. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds. You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher. T.

T. ROWE PRICE DIVERSIFIED MID-CAP GROWTH FUND - -------------------------------------------------------------------------------- December 31, 2004 NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES T. Rowe Price Diversified 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 commenced operations on December 31, 2003. The fund seeks long-term growth of capital by investing primarily in common stocks of medium-sized growth companies. 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, for certain markets, the official closing price at the time the valuations are made, except for OTC Bulletin Board securities, which are valued at the mean of the latest bid and asked prices. 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 asked 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, including restricted securities, 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. 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. 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. 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 are declared and paid on an annual basis. Capital gain distributions, if any, are declared and paid by the fund, typically 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. Securities Lending The fund lends its securities to approved brokers to earn additional income. It receives as collateral cash and U.S. government securities valued at 102% to 105% of the value of the securities on loan. Cash collateral is invested in a money market pooled trust managed by the fund's lending agent in accordance with investment guidelines approved by fund management. Collateral is maintained over the life of the loan in an amount not less than the value of loaned securities, as determined at the close of fund business each day; any additional collateral required due to changes in security values is delivered to the fund the next business day. Although risk is mitigated by the collateral, the fund could experience a delay in recovering its securities and a possible loss of income or value if the borrower fails to return the securities. Securities lending revenue recognized by the fund consists of earnings on invested collateral and borrowing fees, net of any rebates to the borrower and compensation to the lending agent. At December 31, 2004, the value of loaned securities was $3,714,000; aggregate collateral consisted of $3,819,000 in the money market pooled trust. Other Purchases and sales of portfolio securities, other than short-term securities, aggregated $39,215,000 and $3,883,000, respectively, for the year ended December 31, 2004. NOTE 3 - FEDERAL INCOME TAXES No provision for federal income taxes is required since the fund intends 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, 2004. At December 31, 2004, the tax-basis components of net assets were as follows: - -------------------------------------------------------------------------------- Unrealized appreciation $ 5,173,000 Unrealized depreciation (1,311,000) Net unrealized appreciation (depreciation) 3,862,000 Undistributed ordinary income 61,000 Paid-in capital 36,925,000 Net assets $ 40,848,000 -------------------- For the year ended December 31, 2004, the fund recorded the following permanent reclassifications to reflect tax character. Reclassifications to paid-in capital relate primarily to nondeductible organizational expenses. Reclassifications between income and gain relate primarily to the offset of the current net operating loss against realized gains. Results of operations and net assets were not affected by these reclassifications. - -------------------------------------------------------------------------------- Undistributed net investment income $ 215,000 Undistributed net realized gain (213,000) Paid-in capital (2,000) At December 31, 2004, the cost of investments for federal income tax purposes was $40,861,000. 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, 2004, the effective annual group fee rate was 0.31%, and investment management fee payable totaled $15,000. The fund is also subject to a contractual expense limitation through April 30, 2006. During the limitation period, the manager is required to waive its management fee and reimburse the fund for any expenses, excluding interest, taxes, brokerage commissions, and extraordinary expenses, that would otherwise cause the fund's ratio of total expenses to average net assets (expense ratio) to exceed its expense limitation of 1.25%. For a period of three years after the date of any reimbursement or waiver, the fund is required to repay the manager for expenses previously reimbursed and management fees waived to the extent its net assets have grown or expenses have declined sufficiently to allow repayment without causing the fund's expense ratio to exceed its expense limitation. Pursuant to this agreement, at December 31, 2004, management fees waived in the amount of $129,000 remain subject to repayment by the fund. 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 price and maintains the financial records of the fund. T.

ROWE PRICE DIVERSIFIED MID-CAP GROWTH FUND - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Board of Directors and Shareholders of T. Rowe Price Diversified Mid-Cap Growth Fund, Inc. In our opinion, the accompanying statement of assets and liabilities, including the portfolio of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of T. Rowe Price Diversified Mid-Cap Growth Fund, Inc. (the "Fund") at December 31, 2004, and the results of its operations, the changes in its net assets and the financial highlights for the fiscal period presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2004 by correspondence with the custodian, provide a reasonable basis for our opinion.
