By comparison, the unmanaged S&P 500 Index produced a total return of +16.52%. While we strive for the funds to outperform the S&P 500 every year, the goal of all three funds is to generate higher returns than the S&P 500 over longer periods of time. Over the past five years and since inception, returns for all three PRIMECAP Odyssey Funds are well ahead of that of the S&P 500. Returns for the PRIMECAP Odyssey Growth Fund and the PRIMECAP Odyssey Aggressive Growth Fund are also ahead of the returns of their secondary indices, the Russell 1000 Growth Index and the Russell Midcap Growth Index, respectively. - -------------------------------------------------------------------------------- ANNUALIZED TOTAL RETURNS AS OF 10/31/10 - -------------------------------------------------------------------------------- SINCE INCEPTION 1-YEAR 5-YEAR (11/1/04) - -------------------------------------------------------------------------------- PRIMECAP Odyssey Stock Fund(1) 16.14% 4.03% 5.75% - -------------------------------------------------------------------------------- PRIMECAP Odyssey Growth Fund(1) 20.96% 5.30% 7.05% - -------------------------------------------------------------------------------- PRIMECAP Odyssey Aggressive Growth Fund(1) 31.14% 7.98% 8.71% - -------------------------------------------------------------------------------- S&P 500 16.52% 1.73% 2.86% - -------------------------------------------------------------------------------- Russell 1000 Growth 19.65% 3.22% 4.15% - -------------------------------------------------------------------------------- Russell Midcap Growth 28.03% 4.28% 6.15% - -------------------------------------------------------------------------------- (1) Total expense ratio as reported in Prospectus dated 2/26/10: PRIMECAP Odyssey Stock Fund: 0.81%; PRIMECAP Odyssey Growth Fund: 0.73%; PRIMECAP Odyssey Aggressive Growth Fund: 0.79%.

Before we begin a discussion of the investment environment and the funds' results, we would like to take a moment to address the issue of capital gains distributions. While we measure the long-term results of the funds by pre-tax total return, we are aware of the tax consequences of our investment decisions. As long-term investors, we hold most of our positions for years, not months. 2 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- CONTINUED This year, however, several of our portfolio companies were acquired at considerable premiums, resulting in capital gains. While most of these gains were offset by loss carryovers from previous years, the PRIMECAP Odyssey Aggressive Growth Fund has plans to distribute a long-term capital gain in December 2010. As mentioned above, the S&P 500 posted solid positive returns for the fiscal year, led by the consumer discretionary and industrials sectors. However, it was a volatile period marked by several significant rallies and declines in the market. The S&P 500 climbed over 15% in the first half of the fiscal year, declined into negative territory by early July, and then finished the fiscal year with a strong rally the last two months. The economy has continued to grow at a modest pace as it recovers from the recession that began in late 2007. While corporate earnings have rebounded strongly and the financial markets appear to have stabilized, there are still troubling economic indicators, such as high unemployment and a weak housing market. All three PRIMECAP Odyssey Funds are overweight in the health care and information technology sectors and underweight in the financials, consumer staples, and energy sectors. The health care sector, which lagged the overall S&P 500 over the past fiscal year, has been plagued by a barrage of unfavorable news. The Patient Protection and Affordable Care Act passed in March will lead to various forms of pricing pressure for companies in the sector. The weak economy and high unemployment has reduced the number of visits to physicians' offices and the overall demand for health care, particularly those elective treatments and procedures which can be postponed. Despite these challenges, we remain optimistic about our health care holdings. The pricing concerns raised by health care reform legislation should be partially offset by the 30 million currently uninsured people who will gain coverage as a result. We believe that the pharmaceutical, biotechnology, and medical device products currently in development represent a more efficient way to treat diseases such as Alzheimer's, diabetes, and cancer than the current standard of care. The aging demographics in the United States, Europe, and Japan, along with rising standards of living in developing markets such as China and India, should lead to greater increases in the demand for health care products. The information technology sector, which posted higher returns than the overall S&P 500 over the past 12 months, remains attractive for several reasons. First, internet usage has continued to grow, driven by social networking, e-commerce, and the growth of devices such as smartphones and tablet computers. Second, demand for semiconductors, computer hardware, and storage has remained robust as consumers generate increasing amounts of data, photos, and videos. Third, emerging middle-class consumers in developing economies represent a vast new potential audience for technology products and services. Finally, many companies in the information technology sector have strong balance sheets with cash at record levels. A more detailed discussion of the results of each PRIMECAP Odyssey Fund follows. 3 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- CONTINUED PRIMECAP ODYSSEY STOCK FUND From November 1, 2009 to October 31, 2010, the Stock Fund's total return of +16.14% slightly trailed the S&P 500's total return of +16.52%, mainly due to its overweight position and poor stock selection in the health care sector. The fund's results were also hurt by its average cash position of nearly 10% during the fiscal year and by poor stock selection in the consumer discretionary sector. Positive stock selection and an overweight position in the industrials sector, along with underweight positions in the financials and energy sectors, benefited the fund. Two health care companies were among the largest detractors from fund results. Roche Holding AG (-5.6%), a Swiss pharmaceutical and biotechnology firm which is the fund's largest holding, struggled due to concerns regarding the efficacy and high cost of its cancer drug, Avastin. Looking forward, Roche faces fewer challenges from patent expirations than its pharmaceutical competitors, and we are optimistic about its pipeline for new drugs. Medical device manufacturer Boston Scientific's (-21.3%) earnings declined following a 30-day recall of its implantable cardiac defibril-lators. Holdings in other sectors that hurt the fund's results included Vulcan Materials (-18.9%) and Symantec (-7.9%). On the positive side, three industrial companies were among the top contributors to fund results: Southwest Airlines, Boeing, and Rockwell Automation. Earnings at Southwest Airlines (+64.1%) have rebounded as air travel volumes recovered. We believe the company's recently announced acquisition of AirTran will likely prove to be a good strategic decision. Boeing (+51.9%) appears well-positioned to benefit from the expected growth in global air travel, particularly in the emerging markets. Rockwell Automation (+56.0%), a provider of industrial automation control and information solutions, has benefited from the recovery in industrial production. Other top contributors included Biogen Idec (+48.8%), Texas Instruments (+28.5%), and Altera (+35.9%). 4 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- CONTINUED The top 10 holdings, which collectively represent 29.8% of the portfolio at the period end, are listed below: PRIMECAP ODYSSEY STOCK FUND ENDING % OF TOP 10 HOLDINGS AS OF 10/31/10 TOTAL PORTFOLIO* - -------------------------------------------------------------------------------- Roche Holding AG 4.4 - -------------------------------------------------------------------------------- Amgen Inc. 4.2 - -------------------------------------------------------------------------------- Texas Instruments Inc. 3.5 - -------------------------------------------------------------------------------- Eli Lilly & Co. 3.1 - -------------------------------------------------------------------------------- Marsh & McLennan Cos. 3.1 - -------------------------------------------------------------------------------- Novartis AG (ADS) 2.6 - -------------------------------------------------------------------------------- Medtronic Inc. 2.5 - -------------------------------------------------------------------------------- Microsoft Corp. 2.4 - -------------------------------------------------------------------------------- GlaxoSmithKline PLC ADS 2.1 - -------------------------------------------------------------------------------- Schweitzer-Mauduit Intl.

PRIMECAP ODYSSEY GROWTH FUND From November 1, 2009 to October 31, 2010, the Growth Fund's total return was +20.96% compared with the S&P 500's total return of +16.52% and the Russell 1000 Growth Index's total return of +19.65%. Positive stock selection in the health care and information technology sectors was a major contributor to fund results relative to the S&P 500. The fund also benefited from its underweight position in the financials and energy sectors, further helped by favorable stock selection in both sectors. Two of the top contributors to the fund's results were health care stocks: Crucell N.V. (+62.0%) and Cepheid (+58.6%). The stock price of Crucell, a maker of vaccines based in the Netherlands, surged when Johnson & Johnson announced an agreement to acquire the shares of Crucell that it did not already own at a substantial premium. Cepheid, a manufacturer of medical diagnostic tools, experienced rapid sales growth of its tests that detect bacteria responsible for serious hospital-related infections. Altera (+59.3%), Stratasys (+98.5%), and Southwest Airlines (+64.1%) were among the holdings in other sectors that helped the fund's returns. 5 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- CONTINUED Although our selections in the health care sector made a positive contribution to returns for the fiscal year, several health care stocks were among the largest detractors from the fund's results, including two of the fund's largest holdings: Conceptus (-19.0%) and Roche Holding AG (-5.6%). As an alternative to tubal ligation for women, Conceptus manufactures a minimally invasive birth control device for women. The company has experienced a slower than expected increase in sales. Over time, we believe that the advantages of the company's product and procedure will establish it as the standard of care for physicians and their patients. Holdings in other sectors that hurt the fund's returns included FormFactor (-42.7%) and Electronic Arts (-13.2%). The top 10 holdings, which collectively represent 28.4% of the portfolio at the period end, are listed below: PRIMECAP ODYSSEY GROWTH FUND ENDING % OF TOP 10 HOLDINGS AS OF 10/31/10 TOTAL PORTFOLIO* - -------------------------------------------------------------------------------- Crucell N.V.

PRIMECAP ODYSSEY AGGRESSIVE GROWTH FUND From November 1, 2009 to October 31, 2010, the Aggressive Growth Fund's total return was +31.14%. This compares favorably to the S&P 500's total return of +16.52% and the Russell Midcap Growth Index's total return of +28.03%. The largest single contributor to the fund's results relative to the S&P 500 was the fund's largest position, American Italian Pasta (+95.6%), which was acquired in July at a substantial premium by Ralcorp Holdings. Positive stock selection and the fund's overweight position in the information technology sector along with positive stock 6 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- CONTINUED selection in the health care sector were major contributors to the fund's relative return, which was further helped by its underweight position in the financials sector. With corporations holding unprecedented levels of cash and earning virtually no return on that cash, we believe we have entered an unusual period that will be characterized by heightened acquisition activity and consolidation. In addition to American Italian Pasta, two other holdings benefited from acquisition offers at significant premiums. Vaccine manufacturer Crucell N.V. (+62.0%) agreed to be acquired by Johnson & Johnson, and storage solution provider 3Par Inc. (+202.0%) was acquired by Hewlett-Packard (HP). Biotechnology firm Pharmacyclics (+213.8%) announced positive results for its drug to treat various types of lymphomas. Stratasys Inc. (+98.5%), manufacturer of 3-D printers, signed a collaboration agreement with HP that will enable it to take advantage of HP's broader sales and distribution capabilities. On the negative side, InterMune Inc. (-71.1%), FormFactor Inc. (-42.7%), and Conceptus Inc. (-19.0%) were among the biggest detractors from the fund's returns. FormFactor, a leading provider of testing equipment used by semiconductor manufacturers, suffered from operational miscues. Following the hiring of a new management team and significant restructuring, we expect the company to recapture technological leadership and gain market share.

With 10-year Treasury bonds yielding less than 3% and money market funds yielding virtually nothing, we believe stocks, with a prospective earnings yield of over 7.5% and the potential for capital appreciation, represent an attractive alternative. However, there are several macro-level concerns that temper our optimism. The current fiscal and monetary policies in the United States may ultimately lead to a rise in inflation and a weaker U.S. dollar - which recently touched a 15-year low against the Japanese yen and has weakened against the euro. Longer term, we believe it will be difficult for the United States to sustain current fiscal policies in an environment where spending needs and future obligations are increasing faster than tax revenues. As the recent problems in Greece, Ireland, and other European countries demonstrate, it is difficult to increase government spending more rapidly than the growth rate of the broader economy for an extended period. Increased regulations and other government intervention into the private sector are even more troubling, as they distort economic incentives and introduce uncertainty about the future environment for businesses and consumers. We believe that market forces result in a more efficient allocation of resources than government programs. Despite these concerns, we have a generally positive outlook for U.S. equities. We believe valuations for many companies are attractive relative to their prospects for revenue and earnings growth and the strength and quality of their balance sheets. We would highlight three factors. First, many U.S. companies appear well-positioned to benefit from the long-term impact of globalization and the continued development of emerging markets. While growth in the domestic economy may be moderate at best, many U.S. corporations generate an increasing portion of their revenues and earningsfrom abroad . Second,we are enthusiastic about the potential for innovation by U .S. companies. We expect that substantial investment in research and development will lead to the development of new products and services that improve productivity for businesses and quality of life for consumers. This should result in revenue and earnings growth opportunities that are not reflected in current expectations. In particular, we remain committed to our sizeable holdings in the health care and information technology sectors. These two sectors also represent areas where the United States has a strong competitive advantage relative to the rest of the world. Third, the balance sheets of U.S. corporations are as strong and liquid as they have ever been. Many companies are holding considerable cash balances, which represent an under-utilized asset in the current low interest rate environment but could be a source of higher returns in the future. We will continue to look for opportunities to invest in companies with strong balance sheets that we believe are well-positioned to benefit from innovation and globalization.

This expense example is intended to help you understand your ongoing costs (in dollars) of investing in the funds and to compare these costs with the ongoing costs of investing in other mutual funds. The expense example is based on an investment of $1,000 invested for a six month period beginning April 30, 2010 and held through October 31, 2010. ACTUAL EXPENSES The information in the table adjacent to the heading "Actual Performance" provides actual account values and actual expenses. You may use the information in these columns, together with the amount you invested, 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 column entitled "Expenses Paid during Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The information in the table adjacent to the heading "Hypothetical Performance (5% return before expenses)" provides hypothetical account values and hypothetical expenses based on the funds' actual expense ratios and an assumed rate of return of 5% per year before expenses, which are not the funds' actual returns. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the funds and other mutual funds. To do so, compare these 5% hypothetical examples with the 5% hypothetical examples that appear in the shareholder reports of the other mutual funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the information adjacent to the heading "Hypothetical Performance (5% return before expenses)" is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different mutual funds. In addition, if transactional costs were included, your costs would have been higher. 13 EXPENSE EXAMPLE PRIMECAP ODYSSEY FUNDS - ------------------------------------------------------------------------------------- (UNAUDITED) - CONTINUED BEGINNING ENDING EXPENSES PAID EXPENSE RATIO ACCOUNT ACCOUNT DURING PERIOD* DURING PERIOD* VALUE VALUE (04/30/10 TO (04/30/10 TO (04/30/10) (10/31/10) 10/31/10) 10/31/10) - ------------------------------------------------------------------------------------- PRIMECAP ODYSSEY STOCK FUND Actual Performance $1,000.00 $ 991.20 $3.55 0.71% Hypothetical Performance (5% return before expenses) $1,000.00 $1,021.64 $3.60 0.71% PRIMECAP ODYSSEY GROWTH FUND Actual Performance $1,000.00 $1,009.60 $3.46 0.68% Hypothetical Performance (5% return before expenses) $1,000.00 $1,021.77 $3.48 0.68% PRIMECAP ODYSSEY AGGRESSIVE GROWTH FUND Actual Performance $1,000.00 $1,019.50 $3.63 0.71% Hypothetical Performance (5% return before expenses) $1,000.00 $1,021.61 $3.63 0.71% - ------------------------------------------------------------------------------------- - -------- * Expenses are equal to a fund's annualized expense ratio as indicated, multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year period (184), then divided by the number of days in the fiscal year (365) to reflect the one-half year period. 14 SECTOR BREAKDOWN PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- PRIMECAP ODYSSEY STOCK FUND - -------------------------------------------------------------------------------- Consumer Discretionary 7.7% Consumer Staples 1.9% Energy 7.2% Financials 5.8% Health Care 25.2% Industrials 13.1% Information Technology 21.4% Materials 7.6% Telecommunication Services 0.1% Utilities 1.3% Short Term Investments and Other Net Assets 8.7% - -------------------------------------------------------------------------------- TOTAL 100.0% - -------------------------------------------------------------------------------- PRIMECAP ODYSSEY GROWTH FUND - -------------------------------------------------------------------------------- Consumer Discretionary 7.1% Consumer Staples 0.4% Energy 4.9% Financials 3.2% Health Care 38.6% Industrials 9.3% Information Technology 28.7% Materials 3.2% Telecommunication Services 0.1% Short Term Investments and Other Net Assets 4.5% - -------------------------------------------------------------------------------- TOTAL 100.0% - -------------------------------------------------------------------------------- The tables above list sector allocations as a percentage of each fund's total net assets as of October 31, 2010.

Each Fund's investment objective is to provide long-term capital appreciation. Each Fund is authorized to issue unlimited shares of beneficial interest. All shares within each Fund have equal rights with respect to voting. (2) SIGNIFICANT ACCOUNTING POLICIES The Funds consistently follow the accounting policies set forth below which are in conformity with accounting principles generally accepted in the United States of America. A. SECURITY VALUATION. Securities traded on a national securities exchange are valued at the last reported sales price at the close of regular trading on each day the exchanges are open for trading. Securities listed on the NASDAQ Global Market, the NASDAQ Global Select Market, and the NASDAQ Capital Market are valued using the NASDAQ Official Closing Price, which may not necessarily represent the last sale price. Quotations of foreign securities in a foreign currency are valued daily in U.S. dollars on the basis of the foreign currency exchange rates prevailing at the time such valuation is determined. Foreign currency exchange rates generally are determined prior to the close of the New York Stock Exchange (the "NYSE"). Securities traded on an exchange for which there have been no sales are valued at the mean between the bid and asked price. Securities for which quotations are not readily available are stated at their respective fair values as determined in good faith by a valuation committee of the Investment Advisor in accordance with procedures approved by the Trust's board of trustees. In determining fair value, the Funds take into account all relevant factors and available information. Consequently, the price of a security used by a Fund to calculate its net asset value per share ("NAV") may differ from quoted or published prices for the same security. Fair value pricing involves subjective judgments, and there is no single standard for determining a security's fair value. As a result, different mutual funds could reasonably arrive at a different fair value for the same security. It is possible that the fair value determined for a security is materially different from the value that could be realized upon the sale of that security or from the values that other mutual funds may determine. Investments in other funds are valued at their respective net asset values as determined by those funds, in accordance with the 1940 Act. 37 NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- FOR THE YEAR ENDED OCTOBER 31, 2010 - CONTINUED Foreign securities are recorded in the financial statements after translation to U.S. dollars based on the applicable exchange rate at the end of the period. The Funds do not isolate that portion of the results of operations arising as a result of changes in the currency exchange rate from the fluctuations arising as a result of changes in the market prices of investments during the period. B. SHARE VALUATION. The net asset value per share ("NAV") of a Fund is calculated by dividing the sum of the value of the securities held by the Fund, plus cash or other assets, minus all liabilities (including estimated accrued expenses) by the total number of shares outstanding of the Fund. The result is rounded to the nearest cent. The Funds' shares will not be priced on the days on which the NYSE is closed for trading. C. FOREIGN CURRENCY. Values of investments denominated in foreign currencies are converted into U.S. dollars using the spot market rate of exchange at the time of valuation. Purchases and sales of investments and dividend and interest income are translated into U.S. dollars using the spot market rate of exchange prevailing on the respective dates of such translations. The gain or loss resulting from changes in foreign exchange rates is included with net realized and unrealized gain or loss from investments, as appropriate. Foreign securities and currency transactions may involve certain considerations and risks not typically associated with those of domestic origin. D. FEDERAL INCOME TAXES. Each Fund has elected to be treated as a "regulated investment company" under Subchapter M of the Internal Revenue Code. The Funds intend to distribute substantially all of their taxable income and any capital gains in excess of applicable capital loss carryforwards. Accordingly, no provision for Federal income taxes has been made in the accompanying financial statements. The Funds may be subject to foreign taxes on income, gains on investments, or currency repatriation, a portion of which may be recoverable. The Funds will accrue such taxes and recoveries as applicable based upon their current interpretations of the tax rules and regulations that exist in the markets in which they invest. There is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken on the tax return for the fiscal year-end October 31, 2010, or for any other tax years which are open for exam. As of October 31, 2010, open tax years include the tax years ended October 31, 2007 through 2010. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next six months. The Funds recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations. During the period, the Funds did not incur any interest or penalties. 38 NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- FOR THE YEAR ENDED OCTOBER 31, 2010 - CONTINUED E. ALLOCATION OF EXPENSES. Each Fund is charged for those expenses directly attributable to it. Expenses that are not directly attributable to a Fund are allocated among the Funds in proportion to their respective assets or another appropriate method. F. SECURITY TRANSACTIONS, INVESTMENT INCOME, AND DISTRIBUTIONS. Security transactions are accounted for on the trade date. Dividend income and distributions to shareholders are recorded on the ex-dividend date, and interest income is recognized on the accrual basis. Realized gains and losses are evaluated on the basis of identified costs. Premiums and discounts on the purchase of securities are amortized/ accreted using the effective interest method. Accounting principles generally accepted in the United States of America require that permanent financial reporting and tax differences be reclassified in the capital accounts. G. USE OF ESTIMATES. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. H. INDEMNIFICATION OBLIGATIONS. Under the Trust's organizational documents, its current and former officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that contain a variety of representations and warranties that provide general indemnifications. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. Based on experience, the Funds would expect the risk of loss to be remote. (3) INVESTMENT TRANSACTIONS The cost of purchases and the proceeds from sales of securities, excluding short-term investments, for the year ended October 31, 2010 were as follows: FUND PURCHASES SALES - ---- --------- ----- PRIMECAP Odyssey Stock Fund ............... $343,180,369 $10,243,036 PRIMECAP Odyssey Growth Fund .............. $588,365,944 $48,448,013 PRIMECAP Odyssey Aggressive Growth Fund ... $363,755,688 $79,661,206 39 NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- FOR THE YEAR ENDED OCTOBER 31, 2010 - CONTINUED (4) FAIR VALUE OF THE FINANCIAL INSTRUMENTS On January 21, 2010, the FASB issued ASU 2010-06, Improving Disclosures about Fair Value Measurements. ASU 2010-06 amends ASC 820, Fair Value Measurements and Disclosures (formerly FASB Statement No. 157), to require additional disclosures regarding fair measurements. Specifically, the amendment requires reporting entities to disclose i) the inputs and valuation techniques used to measure fair value for both recurring and nonrecurring fair value measurements for Level 2 and Level 3 positions; ii) transfers between all levels including Level 1 and Level 2 as well as the reason(s) for all transfers; and with respect to Level 3 positions, transfers out separately from transfers in; and iii) purchases, sales, issuances, and settlements on a gross basis in the Level 3 roll forward rather than as one net number. Examples of inputs that may be used in valuing Level 2 securities are current yields, current discount rates, credit quality, yields for comparable securities, and trading volume. The effective date of this guidance is for interim and annual periods beginning after December 15, 2009; however, the requirements to provide the Level 3 activity for purchases, sales, issuances, and settlements on a gross basis will be effective for interim and annual periods beginning after December 15, 2010. The Funds follow a fair value hierarchy that distinguishes between market data obtained from independent sources (observable inputs) and the Funds' own market assumptions (unobservable inputs). These inputs are used in determining the value of each Fund's investments and are summarized in the following fair value hierarchy: Level 1 - Quoted prices in active markets for identical securities. Level 2 - Other significant observable inputs (including quoted prices for similar securities, interest rates, foreign exchange rates, and fair value estimates for foreign securities indices). Level 3 - Significant unobservable inputs (including the Funds' own assumptions in determining fair value of investments). The following table provides the fair value measurements of applicable Fund assets by level within the fair value hierarchy for each Fund as of October 31, 2010. These assets are measured on a recurring basis. 40 NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- FOR THE YEAR ENDED OCTOBER 31, 2010 - CONTINUED QUOTED PRICES IN ACTIVE SIGNIFICANT MARKETS FOR OTHER SIGNIFICANT IDENTICAL OBSERVABLE UNOBSERVABLE ASSETS INPUTS INPUTS FUND DESCRIPTION (LEVEL 1) (LEVEL 2) (LEVEL 3) TOTAL - ---- ----------- --------- --------- --------- ----- PRIMECAP Equity ODYSSEY STOCK Common Stock $ 554,183,713 $ -- $ -- $ 554,183,713 FUND ------------- ------ ------ -------------- Total Equity $ 554,183,713 $ -- $ -- $ 554,183,713 ------------- ------ ------ -------------- Short-Term $ 58,019,559 $ -- $ -- $ 58,019,559 ------------- ------ ------ -------------- Investments Total Investments in Securities $ 612,203,272 $ -- $ -- $ 612,203,272 ============= ====== ====== ============== PRIMECAP Equity ODYSSEY GROWTH Common Stock $1,385,763,63 $ -- $ -- $1,385,763,639 FUND ------------- ------ ------ -------------- Total Equity $1,385,763,63 $ -- $ -- $1,385,763,639 ------------- ------ ------ -------------- Short-Term $ 64,962,131 $ -- $ -- $ 64,962,131 ------------- ------ ------ -------------- Investments Total Investments in Securities $1,450,725,77 $ -- $ -- $1,450,725,770 ============= ====== ====== ============== PRIMECAP Equity ODYSSEY Common Stock $ 763,369,539 $ -- $ -- $ 763,369,539 AGGRESSIVE ------------- ------ ------ -------------- GROWTH FUND Total Equity $ 763,369,539 $ -- $ -- $ 763,369,539 ------------- ------ ------ -------------- Short-Term $ 47,491,670 $ -- $ -- $ 47,491,670 ------------- ------ ------ -------------- Investments Total Investments in Securities $ 810,861,209 $ -- $ -- $ 810,861,209 ============= ====== ====== ============== - ------ Refer to each Fund's respective Schedule of Investments for the breakdown of major categories.

These reclassifications have no effect on net assets or net asset value per share. During the fiscal year ended October 31, 2010 the reclassifications were as follows: UNDISTRIBUTED ACCUMULATED NET INVESTMENT NET REALIZED INCOME LOSS PAID IN CAPITAL ------ ---- --------------- PRIMECAP Odyssey Stock Fund ................

In September 2010, the Board of Trustees, including the Independent Trustees, approved a one-year renewal of the Trust's investment advisory agreement (the "Investment Advisory Agreement") with PRIMECAP Management Company (the "Investment Advisor"). GENERAL INFORMATION The following information summarizes the Board's considerations associated with its review of the Investment Advisory Agreement. In connection with their deliberations, the Board considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. The Investment Advisory Agreement was considered separately for each Fund, although the Board took into account the common interests of all the Funds in its review. In considering these matters, the Board discussed the renewal of the Investment Advisory Agreement with management, and the Independent Trustees met in private sessions with counsel at which no employees of the Investment Advisor were present. The Board reviewed extensive materials regarding the investment results of the Funds, advisory fee and expense comparisons, financial and profitability information with respect to the Investment Advisor, descriptions of various functions such as compliance monitoring and portfolio trading practices, and information about the personnel of the Investment Advisor providing services to the Funds. They also took into account information they received at past Board meetings with respect to these matters. In deciding to approve the renewal of the Investment Advisory Agreement, the Board and the Independent Trustees did not identify a single factor as controlling, and this summary does not describe all of the matters considered. However, the Board and the Independent Trustees concluded that each of the various factors referred to below favored such approval. NATURE, EXTENT, AND QUALITY OF SERVICES The Board discussed the services provided by the Investment Advisor to the Funds under the Investment Advisory Agreement, including the background, education, and experience of its key portfolio management and operational personnel; its overall financial strength and stability; its resources and efforts to retain, attract, and motivate capable personnel to serve the Funds; and the overall general quality and depth of its organization. The Board also took into account the experience, capability, and integrity of the Investment Advisor's senior management; its investment philosophy and processes, including its brokerage and trading practices; its disaster recovery and contingency planning; and its commitment and systems in place with regard to compliance with applicable laws and regulations. The Board and the Independent Trustees concluded that the nature, extent, and quality of services provided under the Investment Advisory Agreement were satisfactory. 47 ADDITIONAL INFORMATION PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- (UNAUDITED) - CONTINUED INVESTMENT PERFORMANCE The Board assessed the performance of each Fund compared with its benchmark and the average of a peer group of funds (each a "peer group") selected by Morningstar, Inc. ("Morningstar") for theyear-to-date and one-year, three-year, and five-year andsince-inception periods ended July 31, 2010. The Board made the following observations in reviewing the Funds' performance: o The PRIMECAP Odyssey Stock Fund outperformed the median return of the funds in the Morningstar Large Cap Growth fund peer group and the S&P 500 Index for the three- and five-year periods ended July 31, 2010. The Fund continued to significantly outperform its benchmark in the period from the Fund's inception through July 31, 2010. The Fund had lagged the S&P 500 during the year ended July 31, 2010 but performed in line with its peer group. o The total return of the PRIMECAP Odyssey Growth Fund exceeded the median return of the funds in the Morningstar Large Cap Growth fund peer group, the S&P 500 Index, and the Russell 1000 Growth Index for all periods ended July 31, 2010, except for the S&P 500 Index and the Russell 1000 Growth Index for the one-year period. The return from the Fund's inception through July 31, 2010 was also better than those of the S&P 500 and the Russell 1000 Growth Index. o The performance of the PRIMECAP Odyssey Aggressive Growth Fund exceeded that of the median return of the funds in the Morningstar Mid-Cap Growth fund peer group and the S&P 500 Index for the year-to-date, three-year and five-year periods ended July 31, 2010. The Fund also outperformed the S&P 500 Index and the Russell MidCap Growth Index from the Fund's inception through July 31, 2010. The Fund's performance over the 12 months ended July 31, 2010 was slightly lower than that of the Russell MidCap Growth Index but significantly higher than that of the S&P 500. Based on the information provided to them, the Board and the Independent Trustees concluded that the performance of each Fund was satisfactory. ADVISORY FEES AND FUND EXPENSES The Board reviewed the fees and expenses paid by each Fund to the Investment Advisor and an analysis of Morningstar data with respect to the fees and expenses paid by comparable funds, noting in particular that: o The PRIMECAP Odyssey Stock Fund had the lowest advisory fee and the third-lowest total expense ratio in its Morningstar peer group. o The PRIMECAP Odyssey Growth Fund's advisory fees and total expense ratio were in the lowest quartiles of its Morningstar peer group. o The advisory fee charged to the PRIMECAP Odyssey Aggressive Growth Fund was the lowest in the Morningstar peer group, and the Fund's total expenses were in the lowest quartile of the peer group. 48 ADDITIONAL INFORMATION PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- (UNAUDITED) - CONTINUED The Board also reviewed the fees charged by the Investment Advisor to other clients, including other funds for which it serves as sub-adviser. The Board noted that, although such fees were lower than those charged to the Funds, the Investment Advisor provided additional services to the Funds that it did not provide to other clients. The Board and the Independent Trustees determined that the advisory fees and expenses charged to the Funds were reasonable in consideration of the services provided. COSTS AND PROFITS OF THE INVESTMENT ADVISOR The Board reviewed information relating to the costs of the Investment Advisor in providing services under the Investment Advisory Agreement and the Investment Advisor's profitability under that Agreement. The Board noted that, at the Funds' current asset levels, the Investment Advisory Agreement was less profitable to the Investment Advisor than its other advisory relationships. The Board and the Independent Trustees determined that the Investment Advisor's profitability under the Investment Advisory Agreement was reasonable in light of the nature, extent, and quality of the services provided to the Funds. ECONOMIES OF SCALE AND OTHER BENEFITS TO THE INVESTMENT ADVISOR The Board reviewed whether the Funds had achieved economies of scale, noting that the Funds' asset levels had fluctuated significantly during the past 12 months. The Board and the Independent Trustees noted that the current asset levels of the Funds were not so substantial as to lead to economies of scale that would necessitate including additional breakpoints in the advisory fee schedule. The Board also considered the benefits received by the Investment Advisor as a result of its relationship with the Funds, including investment advisory fees and the intangible benefits of any favorable publicity arising in connection with the Funds' performance. CONCLUSIONS Based on their review, including their consideration of each of the factors referred to above, the Board and the Independent Trustees concluded that the compensation payable to the Investment Advisor pursuant to the Investment Advisory Agreement is fair and reasonable in light of the services being provided by the Investment Advisor to the Funds and their shareholders, and that renewal of the Investment Advisory Agreement was in the best interest of the Funds and their shareholders. 49 MANAGEMENT PRIMECAP ODYSSEY FUNDS - -------------------------------------------------------------------------------- (UNAUDITED) PORTFOLIO MANAGERS PRIMECAP Management Company has five portfolio managers who together have more than 175 years of investment experience.
