From November 1, 2005 through October 31, 2006, the PRIMECAP Odyssey Stock, Growth, and Aggressive Growth Funds produced total returns of 17.48%, 18.49%, and 23.84%, respectively, versus the S&P 500 total return of 16.34%. Before we begin a discussion of the investment environment and the Funds' results, we would like to address one housekeeping issue. The objective of all three Funds is long-term capital appreciation. While we measure this by pre-tax total returns, we are cognizant of the tax consequences of our investment decisions. As long-term investors, we hold most of our positions for years, not months. This year, however, three of our portfolio companies were acquired, causing unavoidable short-term capital gains. INVESTMENT ENVIRONMENT OF THE FISCAL YEAR Despite concerns about weakness in the housing market, high oil prices, and escalating violence in Iraq, equity markets produced solid returns this year. The Dow Jones Industrial Average reached a new record, and nearly every sector in the S&P 500 produced sizable gains. It was a volatile year for equity investors, as the aforementioned concerns, combined with fears of ongoing interest rate hikes, produced minimal returns for the first seven months of the fiscal year. When the Federal Reserve paused its campaign of interest rate increases, and oil prices retreated from their highs, equity markets rallied, and the S&P 500 finished the year up 16.34%. Oil prices began the fiscal year near $60/barrel, surpassed $75/barrel in July, and then retreated to nearly $60/barrel by the end of October 2006. Persistently high energy prices led to another strong year for the Energy sector, which gained 19.3%. Despite the burden on consumers of continued high energy prices, consumers remained resilient. The Consumer Discretionary sector, an area of significant commitment for the Funds, was one of the better performing sectors in the market, gaining 18.2%. This year, we observed many industries adapt to oil price volatility. The Airline industry, an area currently favored by the Funds, has dramatically slashed its operating costs, enabling many carriers to return to profitability despite $60/barrel oil. Another issue, which we have commented on in the past, is a compression of the multiple differential between growth stocks and value stocks. For the year ended October 31, 2006, value stocks continued to significantly outperform growth stocks. The Russell 1000 Value Index posted a total return of 21.46% this year, significantly outperforming the Russell 1000 Growth Index's return of 10.84%. This return differential between value and growth is unlikely to persist indefinitely, as it would result in companies with slower earnings growth trading at premiums to those with faster earnings growth, an unsustainable scenario in our view. We believe that many growth stocks are undervalued. Most of our growth stocks that have outperformed have done so primarily via earnings growth; few have seen meaningful multiple expansion. 2 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS In all three PRIMECAP Odyssey Funds, favorable stock selection offset extremely unfavorable sector allocation. Our most heavily weighted sectors in all three Funds, Health Care and Information Technology, were the two worst performing sectors of the S&P 500 during the fiscal year. We feel fortunate to have outperformed with such unfavorable sector allocation and remain optimistic that these two sectors, which continue to be our most heavily weighted, will see above average returns in the coming years. A more detailed discussion of the results of each PRIMECAP Odyssey Fund follows. PRIMECAP ODYSSEY STOCK FUND From November 1, 2005 to October 31, 2006, the PRIMECAP Odyssey Stock Fund's total return of 17.48% exceeded the 16.34% return recorded by the unmanaged Standard & Poor's 500 Composite Stock Price Index (S&P 500). The Stock Fund's outperformance was driven primarily by stock selection, which offset unfavorable results from sector allocation. The most notable performance in the Stock Fund was our Consumer Discretionary holdings, which appreciated 39.7% versus the S&P 500 Consumer Discretionary sector return of 18.2%. The results were primarily attributable to our investments in retailers Kohl's (+46.7%) and Dress Barn (+63.5%). Strong performance among our Information Technology (IT) selections also contributed significantly to the Stock Fund's returns, more than offsetting our heavy allocation to this underperform-ing sector. Our IT investments appreciated 17.9% versus the S&P 500 IT sector return of 9.5%. Intuit gained 53.7%, owing to strong growth in TurboTax and QuickBooks. Other important contributors to this performance included NVIDIA, which gained 107.9%, and ASML, which gained 34.5%. NVIDIA continues to gain market share in graphics processors, and ASML widened its technology leadership and market share in lithography tools used in semiconductor manufacturing. The Stock Fund also benefited from its Industrials holdings, which returned 27.7% versus the S&P 500 Industrial sector return of 16.2%. McDermott, our strongest contributor to this Fund's return, appreciated 84.6%, owing to strong growth in demand for its hydrocarbon development and service capabilities. Our most heavily weighted sector this year was Health Care, which constituted 22.9% of our portfolio and exceeded the benchmark weighting by 10 percentage points. Our Health Care investments, which appreciated 9.6%, lagged the S&P 500 Health Care sector return of 11.4%, and the S&P 500. Substantial declines from Boston Scientific (-32.2%), Medtronic (-13.4%), and Affymetrix (-43.8%) offset strong results from Pfizer (+27.1%) and Eli Lilly (+15.9%). Both Boston Scientific and Medtronic experienced a dramatic slowdown in implantable defibrillator sales as product recalls, FDA inquiries, safety concerns, and the threat of declining reimbursement rates have had a short-term impact on growth rates and investor psychology. Additionally, Boston Scientific has found the initial integration of Guidant to be more challenging than expected. Affymetrix, a pioneer in the gene expression and genotyping markets, has seen its early lead in genotyping eroded by newer technologies. 3 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS The table below lists the top 10 holdings, which collectively represent 25.3% of the total net assets at the fiscal year end. --------------------------------------------------------------------- PRIMECAP ODYSSEY STOCK FUND ENDING % OF TOP 10 HOLDINGS AS OF 10/31/06 TOTAL NET ASSETS --------------------------------------------------------------------- Novartis AG 3.30 Medtronic Inc. 3.30 Eli Lilly & Co. 3.26 Sony Corp. 2.65 Amgen Inc. 2.61 GlaxoSmithKline PLC 2.29 Affymetrix Inc. 2.05 Avery Dennison Corp. 2.02 Boston Scientific Corp. 2.01 Bed Bath & Beyond Inc. 1.78 --------------------------------------------------------------------- TOTAL % OF NET ASSETS 25.27 --------------------------------------------------------------------- With pharmaceuticals trading near 40-year trough relative price-to-earnings ratios (P/Es), we continue to heavily weight these positions. In our view, Novartis, Eli Lilly, and GlaxoSmithKline all have exciting pipelines and low near-term patent expiration exposure. We also believe that the short-term issues currently plaguing Boston Scientific and Medtronic will ultimately be favorably resolved. PRIMECAP ODYSSEY GROWTH FUND From November 1, 2005 to October 31, 2006, the PRIMECAP Odyssey Growth Fund's total return of 18.49% exceeded the 16.34% return recorded by the unmanaged Standard & Poor's 500 Composite Stock Price Index (S&P 500) and the 10.84% return recorded by the Russell 1000 Growth Index. The Growth Fund's outperformance was driven primarily by stock selection, which offset unfavorable results from sector allocation. Our most heavily weighted sectors in this Fund were Health Care and Information Technology (IT). Together, these two sectors constituted 55.3% of the portfolio. In these two sectors, we have found a number of research-intensive companies that stimulate growth through innovation. We believe that securities of such companies, when purchased at reasonable valuations, tend to outperform over long-term time horizons. Our IT investments constituted 29.3% of the total portfolio, exceeding the S&P 500 IT sector weighting by 14 percentage points. Favorable stock selection more than offset our heavy allocation to this underperforming sector. Our IT investments appreciated 24.3% versus the S&P 500 IT sector return of 9.5%. Intuit, our strongest contributor to the Growth Fund's return, appreciated 53.7%, owing to strong growth in TurboTax and QuickBooks. Other strong contributors included 4 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS ASML (+34.5%), Akamai (+199.7%), NVIDIA (+107.9%), Oracle (+45.7%), and Rambus (+12.4%). ASML widened its technology and market share leadership in lithography tools used in semiconductor manufacturing. Akamai saw strong demand for its Internet content delivery services. Oracle's integration of several acquisitions has resulted in an accelerating application business to complement their dominant database franchise. NVIDIA continues to gain market share in graphics processors. Rambus benefited from improving sentiment regarding the long-term prospects of its technology licensing business. Our Health Care investments constituted 26.0% of the Growth Fund's portfolio and exceeded the S&P 500 Health Care sector weighting by over 13 percentage points. Our Health Care investments, which appreciated 12.9%, exceeded the S&P 500 Health Care sector return of 11.4%, but lagged the return of the S&P 500. Favorable results from Laserscope (+46.2%) and Eli Lilly (+15.9%) offset declines from Affymetrix (-43.8%) and Boston Scientific (-32.2%). Laserscope, a new addition to the portfolio this year, was acquired by American Medical Systems. The table below lists the top 10 holdings, which collectively represent 22.9% of the total net assets at the fiscal year end. --------------------------------------------------------------------- PRIMECAP ODYSSEY GROWTH FUND ENDING % OF TOP 10 HOLDINGS AS OF 10/31/06 TOTAL NET ASSETS --------------------------------------------------------------------- Medtronic Inc. 2.94 Eli Lilly & Co. 2.91 Sony Corp. 2.36 Novartis AG 2.33 Affymetrix Inc. 2.32 ASML Holding N.V. 2.16 Southwest Airlines Co. 2.11 Sepracor Inc. 1.95 Intuit Inc. 1.92 Amgen Inc. 1.88 --------------------------------------------------------------------- TOTAL % OF NET ASSETS 22.88 --------------------------------------------------------------------- With pharmaceuticals trading near 40-year trough relative price-to-earnings ratios (P/Es), we continue to heavily weight these positions in the Growth Fund. In our view, Novartis and Eli Lilly have exciting pipelines and low near-term patent expiration exposure. Similarly, Sepracor recently launched what is arguably the most effective, non-addictive drug on the market for the treatment of insomnia. We are also optimistic about Medtronic. Although its shares are depressed over concerns regarding product safety, efficacy, and the threat of declining reimbursement rates, we believe these issues will ultimately be favorably resolved, and that this diversified manufacturer of implantable medical devices should continue to deliver double digit earnings growth for the foreseeable future. 5 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS PRIMECAP ODYSSEY AGGRESSIVE GROWTH FUND From November 1, 2005 to October 31, 2006, the PRIMECAP Odyssey Aggressive Growth Fund's return of 23.84% exceeded the 16.34% return recorded by the unmanaged Standard & Poor's 500 Composite Stock Price Index (S&P 500) and the 14.51% return recorded by the Russell Midcap Growth Index. The Aggressive Growth Fund's outperformance was driven primarily by stock selection, which offset unfavorable results from sector allocation. Our most heavily weighted sector in this Fund was Information Technology (IT), which constituted 45.0% of our portfolio and exceeded the S&P 500 IT sector weighting by 29 percentage points. Most of the Aggressive Growth Fund's favorable relative returns this year were attributable to our IT selections. Our stock selections earned a 37.6% return versus the S&P 500 IT sector return of 9.5%. Akamai, our strongest contributor to the Aggressive Growth Fund's return, appreciated 170.2%, owing to robust growth in demand for its Internet content delivery services. Other strong contributors in this sector included NVIDIA (+107.9%), FormFactor (+36.1%), ASML (+34.5%), Rambus (+29.9%), Opsware (+76.9%), RADVISION (+47.5%), and Micromuse (+39.3%). NVIDIA continues to gain market share in graphics processors. FormFactor has transformed the wafer probe segment of semiconductor testing, offering unprecedented productivity gains for its customers. ASML widened its technology and market share leadership in lithography tools used in semiconductor manufacturing. Rambus benefited from improving sentiment regarding the long-term prospects of its technology licensing business. RADVISION benefited from continued growth in demand for its video conferencing technologies. Our overweight position in Health Care investments returned 12.3% versus the S&P 500 Health Care gain of 11.4%. Our strongest contributors in this sector were Conceptus (+93.0%) and Laserscope (+46.2%), which offset disappointing results from Affymetrix (-43.8%), Pharmacyclics (-27.2%), and Boston Scientific (-26.2%). Conceptus' non-invasive permanent birth control product, which is safer and more cost effective than other procedures, nearly doubled its sales. Laserscope, a new addition to the portfolio this year, was acquired by American Medical Systems. 6 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS The table below lists the top 10 holdings, which collectively represent 27.1% of the total net assets at the fiscal year end. --------------------------------------------------------------------- PRIMECAP ODYSSEY AGGRESSIVE GROWTH FUND ENDING % OF TOP 10 HOLDINGS AS OF 10/31/06 TOTAL NET ASSETS --------------------------------------------------------------------- ASML Holding N.V. 3.38 Affymetrix Inc. 3.25 American Italian Pasta Co. 3.18 Yahoo! Inc. 2.95 Cymer Inc. 2.65 FormFactor Inc. 2.52 Altera Corp. 2.40 AMR Corp. 2.36 Stratasys Inc. 2.26 Boston Scientific Corp. 2.12 --------------------------------------------------------------------- TOTAL % OF NET ASSETS 27.07 --------------------------------------------------------------------- Our top 10 holdings reflect our ongoing enthusiasm for information technology and semiconductor related companies in particular. ASML, Cymer, and FormFactor are all technological and market share leaders in the design of equipment used to manufacture semiconductor devices. Each of these companies has significantly widened its technological lead over its respective competition this year. Similarly, Altera is one of two dominant suppliers of programmable logic devices, a reprogrammable semiconductor that is found extensively in many telecommunications devices. The top 10 holdings also include a number of names we have continued to add to despite very poor performance this year, namely Affymetrix, Yahoo, and Boston Scientific. Affymetrix, a pioneer in the gene expression and genotyping markets, has seen its early lead in genotyping eroded by newer technologies. We are confident, however, that their new product pipeline will enable the company to regain its competitive position. Similarly, we expect Yahoo to strengthen its competitive position and accelerate its growth with the imminent release of its much-anticipated new monetization and behavioral targeting technologies. Finally, we believe the safety and efficacy concerns surrounding Boston Scientific's implantable defibrillator and drug eluting stent businesses will be favorably resolved. The company has been plagued by product recalls, safety concerns, and the integration of Guidant, a recent acquisition. 7 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS STRUCTURE OF PORTFOLIO, POSITIONING, AND OUTLOOK FOR THE PRIMECAP ODYSSEY FUNDS Although globalization continues to be an engine of economic growth, and we remain optimistic on the U.S. economy, we see conflicting economic signals. Corporate balance sheets are in excellent shape, energy and other commodity prices have retreated from their highs, price-to-earnings ratios are at reasonable levels, and long-term interest rates remain low relative to historic levels. Conversely, the U.S. is still at war, the housing market is showing clear signs of weakness, short-term interest rates are much higher than they have been in recent years, energy and commodity prices remain high relative to historic levels, and corporate profit margins are nearing all-time highs. Within the context of this economic environment, we have continued to heavily weight the Health Care and Information Technology sectors. We believe that our stock selections in both of these sectors have significant appreciation potential, irrespective of how the aforementioned economic forces ultimately evolve. In previous shareholder letters, we have discussed our belief that the pharmaceutical industry is part of the solution to rising health care costs, not part of the problem. As our understanding of genetics and molecular biology continues to advance, the medical profession will have a greater understanding of which genetic traits increase susceptibility to disease, which genetic traits result in improved responsiveness to various drugs, and which genetic traits cause serious side effects. Medical care and drug therapy will be far more customized in the future than it is today. We believe this will improve both the efficacy and cost effectiveness of drugs, relative to other means of providing health care. In the future, the prudent use of prescription drugs may demonstrably lower total health costs by substantially reducing the frequency of hospitalizations, emergency room visits, and surgeries. This will prove to be of critical importance as the aging population and longer life expectancy in the U.S. and other countries will place unprecedented demands on hospitals and physicians. Despite the bright future prospects for the pharmaceutical and biotechnology industries, relative valuations remain near 40-year lows. In our view, the long-term revenue growth opportunity and multiple expansion potential makes the Health Care sector very attractive. In all three PRIMECAP Odyssey Funds, we have increased our already heavy allocation to this sector. We continue to remain heavily invested in Information Technology. As broadband access becomes more pervasive and the Internet becomes more useful and engaging, the complexity and sophistication of the hardware, software, and telecommunications infrastructure supporting the Internet is increasing. We also see significant international opportunities for our IT selections. We believe that China will rapidly increase its consumption of the products, services, and intellectual property that have become integral to modern life in the U.S. and Europe. In all three Funds, we have reduced our allocations to the Energy and Materials sectors. While commodity prices (including hydrocarbons) may see significant short-term volatility, we believe that, in the long-term, commodity price growth will not exceed the rate of inflation. Although demand 8 LETTER TO SHAREHOLDERS PRIMECAP ODYSSEY FUNDS growth in China, India, and other rapidly expanding economies place upward price pressure on commodities, this is a self correcting process as it also creates economic incentives to consume more efficiently, curtail consumption, develop new sources of supply, and find substitutes to reduce dependence on high-priced commodities. In closing, we would like to thank you for entrusting your hard-earned capital with us. We will continue to work diligently to prove worthy of that trust.

THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN INVESTMENT WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. CURRENT PERFORMANCE OF THE FUND MAY BE LOWER OR HIGHER THAN THE PERFORMANCE QUOTED. PERFORMANCE DATA CURRENT TO THE MOST RECENT MONTH END MAY BE OBTAINED BY CALLING 1-800-729-2307. THE FUNDS IMPOSE A 2% REDEMPTION FEE ON SHARES HELD LESS THAN 60 DAYS. PERFORMANCE FIGURES REFLECT THE FEE WAIVER IN EFFECT AND, IN THE ABSENCE OF FEE WAIVERS, TOTAL RETURNS WOULD BE LOWER. SHORT-TERM PERFORMANCE, IN PARTICULAR, IS NOT A GOOD INDICATION OF A FUND'S FUTURE PERFORMANCE, AND AN INVESTMENT SHOULD NOT BE MADE BASED SOLELY ON PAST RETURNS. - ---------- * The S&P 500 Index is an unmanaged index composed of 500 common stocks weighted by market value; its total return includes reinvestment of dividends and is considered representative of the stock market return as a whole. 12 [GRAPHIC] EXPENSE EXAMPLE - (UNAUDITED) PRIMECAP ODYSSEY FUNDS As a shareholder of one or more of the Funds, you incur ongoing costs, including management fees and other fund expenses. This 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 Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period from April 30, 2006 to October 31, 2006. ACTUAL EXPENSES The information in the table under 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 row 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 under 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 under 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 - (UNAUDITED) PRIMECAP ODYSSEY FUNDS - --------------------------------------------------------------------------------------- BEGINNING ENDING EXPENSES PAID EXPENSE RATIO ACCOUNT ACCOUNT DURING PERIOD* DURING PERIOD* VALUE VALUE (4/30/06 TO (4/30/06 TO (4/30/06) (10/31/06) 10/31/06) 10/31/06) - --------------------------------------------------------------------------------------- PRIMECAP ODYSSEY STOCK FUND Actual Performance $1,000.00 $1,033.70 $4.98 0.97% Hypothetical Performance (5% return before expenses) $1,000.00 $1,020.31 $4.94 0.97% PRIMECAP ODYSSEY GROWTH FUND Actual Performance $1,000.00 $1,042.40 $4.67 0.91% Hypothetical Performance (5% return before expenses) $1,000.00 $1,020.64 $4.62 0.91% PRIMECAP ODYSSEY AGGRESSIVE GROWTH FUND Actual Performance $1,000.00 $1,061.80 $5.02 0.97% Hypothetical Performance (5% return before expenses) $1,000.00 $1,020.34 $4.92 0.97% - --------------------------------------------------------------------------------------- - ---------- * Expenses are equal to the Funds' 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 [GRAPHIC] SECTOR BREAKDOWN PRIMECAP ODYSSEY FUNDS PRIMECAP ODYSSEY STOCK FUND ----------------------------------------------------- Consumer Discretionary 16.0% Consumer Staples 0.2% Energy 5.4% Financials 8.0% Health Care 24.8% Industrials 13.4% Information Technology 16.5% Materials 6.6% Telecommunication Services 0.7% Short Term Investments 8.4% ----------------------------------------------------- TOTAL 100.0% ----------------------------------------------------- PRIMECAP ODYSSEY GROWTH FUND ----------------------------------------------------- Consumer Discretionary 13.8% Energy 4.4% Financials 5.6% Health Care 25.3% Industrials 10.2% Information Technology 28.8% Materials 1.3% Telecommunication Services 0.9% Short Term Investments 9.7% ----------------------------------------------------- TOTAL 100.0% ----------------------------------------------------- The tables above list sector allocations as a percentage of each Fund's total investments as of October 31, 2006.

THE ACCOMPANYING NOTES ARE AN INTEGRAL PART OF THESE FINANCIAL STATEMENTS. 36 [GRAPHIC] NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS FOR THE YEAR ENDED OCTOBER 31, 2006 (1) ORGANIZATION PRIMECAP Odyssey Funds (the "Trust") was organized on June 8, 2004 as a Delaware statutory trust and is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"). The Trust is comprised of three series: PRIMECAP Odyssey Stock Fund, PRIMECAP Odyssey Growth Fund, and PRIMECAP Odyssey Aggressive Growth Fund (the "Funds"), each of which is diversified within the meaning of the 1940 Act. PRIMECAP Management Company (the "Investment Advisor") serves as investment advisor to the Funds. The Funds commenced operations on November 1, 2004. Each Fund's investment objective is to seek 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 and the NASDAQ Global Select Market are valued using the NASDAQ Official Closing Price. 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 Board of Trustees. In determining fair value, the Funds take into account all relevant factors and available information. Consequently, the price of the security used by the Fund to calculate its 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 Investment Company Act of 1940. 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. 37 NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS FOR THE YEAR ENDED OCTOBER 31, 2006 - (CONTINUED) B. SHARES VALUATION. The net asset value ("NAV") per share 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. 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. 38 NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS FOR THE YEAR ENDED OCTOBER 31, 2006 - (CONTINUED) 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 Funds' 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, 2006 were as follows: FUND PURCHASES SALES ------------ ------------ PRIMECAP Odyssey Stock Fund $ 48,961,292 $ 2,062,950 PRIMECAP Odyssey Growth Fund $133,539,219 $ 7,276,278 PRIMECAP Odyssey Aggressive Growth Fund $ 79,305,650 $ 6,511,773 (4) DISTRIBUTION TO SHAREHOLDERS Net investment income and net realized gains differ for financial statement and tax purposes due to differing treatments of deferred wash sale losses.

Under the terms of the agreement, each of the Funds will pay a fee equal to the following annual percentages of average net assets: FOR THE FIRST ASSETS IN EXCESS OF $100,000,000 $100,000,000 PER FUND PER FUND ------------- ------------------- PRIMECAP Odyssey Stock Fund ............................ 0.60% 0.55% PRIMECAP Odyssey Growth Fund ........................... 0.60% 0.55% PRIMECAP Odyssey Aggressive Growth Fund ................ 0.60% 0.55% The Investment Advisor has contractually agreed to waive its fees and/or reimburse each Fund through October 31, 2007 to the extent necessary so that its ratio of operating expenses to average net assets will not exceed the following levels: PRIMECAP Odyssey Stock Fund ........................... 1.25% PRIMECAP Odyssey Growth Fund .......................... 1.25% PRIMECAP Odyssey Aggressive Growth Fund ............... 1.25% THESE PERCENTAGES ARE BASED ON THE AVERAGE DAILY NET ASSETS OF THE FUNDS. The Investment Advisor did not seek reimbursement in 2006 for fees waived or expenses paid under this agreement. Mellon Bank, N.A. serves as the Funds' Custodian. U.S. Bancorp Fund Services, LLC ("USBFS") serves as the Administrator, Fund Accountant, and Transfer Agent to the Funds. Quasar Distributors, LLC, an affiliate of USBFS, serves as the Funds' Distributor. (6) ACCOUNTING PRONOUNCEMENTS In December, 2005, the Financial Accounting Standards Board ("FASB") released Financial Accounting Standard Board Statement No. 157 Fair Value Measurements ("SFAS 157"). SFAS 157 establishes a fair valuation hierarchy to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. 41 NOTES TO FINANCIAL STATEMENTS PRIMECAP ODYSSEY FUNDS FOR THE YEAR ENDED OCTOBER 31, 2006 - (CONTINUED) On July 13, 2006, the Financial Accounting Standards Board ("FASB") released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented, and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined. 42 [GRAPHIC] REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of PRIMECAP Odyssey Funds: In our opinion, the accompanying statements of assets and liabilities, including the schedules 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 PRIMECAP Odyssey Stock Fund, PRIMECAP Odyssey Growth Fund, and PRIMECAP Odyssey Aggressive Growth Fund (hereafter referred to as the "Funds") at October 31, 2006, the results of each of their operations for the year then ended and the changes in each of their net assets and the financial highlights for the year then ended and for the period November 1, 2004 (commencement of operations) through October 31, 2005, 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 Funds' 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 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 October 31, 2006 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

During the six months ended October 31, 2006, the Board of Trustees unanimously approved a one-year renewal of the Trust's investment advisory agreement (the "Investment Advisory Agreement") with the Investment Advisor. GENERAL INFORMATION The following information summarizes the Board's considerations associated with its renewal 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. As described below, the Board considered the nature, quality and extent of the various services provided to the Funds by the Investment Advisor as well as the levels of the Funds' advisory fees and other expenses. In considering these matters, the Board discussed the renewal of the Investment Advisory Agreement with management and in private sessions with counsel at which no representatives 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 providing services to the Funds. In deciding to approve the renewal of the Investment Advisory Agreement, the Board did not identify a single factor as controlling and this summary does not describe all of the matters considered. However, the Board concluded that each of the various factors referred to below favored such approval. NATURE, EXTENT AND QUALITY OF SERVICES In reviewing the services provided by the Investment Advisor, the Board discussed the services provided by the Investment Advisor to the Funds under the Investment Management Agreement, including the background, education and experience of the Investment Advisor's 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, trading and soft dollar 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 concluded that the Investment Advisor continued to provide high quality services to the Funds. 45 ADDITIONAL INFORMATION - (UNAUDITED) PRIMECAP ODYSSEY FUNDS INVESTMENT PERFORMANCE The Board assessed the performance of each Fund compared with its respective benchmark and the average of a peer group of funds (each, a "peer group") selected by Lipper, Inc. ("Lipper") for the one-, three- and six-month and one-year periods ended July 31, 2006. The Board observed that the Funds' investment results were good, and that the one-year total return of each of the Funds was above the median return of the funds in its peer group and above the S&P 500 Index. ADVISORY FEES AND FUND EXPENSES The Board reviewed information regarding the advisory fees charged by the Investment Advisor and total expenses of each of the Funds compared to those of the funds included in the relevant Lipper peer group, and observed that those fees were at or below the average of their respective peer groups. The Board also reviewed the fees charged by the Investment Advisor to other clients, including other funds to which the Investment Advisor served as sub-advisor, and noted that although such fees were lower than those charged to the Funds, the Investment Advisor provided additional services to the Trust that it did not provide to other clients. The Trustees reviewed information regarding the Funds' total expense levels compared to those in their respective Lipper peer groups and determined that the Funds' expenses were reasonable and below the medians of the funds in the peer groups. They considered information relating to the Advisor's costs and profits, and noted that given the Funds' current asset levels it was unlikely that the Funds provide substantial profits to the Advisor or could lead to significant economies of scale. The Board concluded that the advisory fees and expenses of the Funds continued to be reasonable. CONCLUSIONS Based on their review, including their consideration of each of the factors referred to above, the Board concluded that the Investment Advisory Agreement represents fair and reasonable compensation in light of the nature and quality of the services being provided by the Investment Advisor to the Trust and the shareholders of the Funds, and that it would be in the best interests of the Funds to renew the Agreement. 46 [GRAPHIC] MANAGEMENT - (UNAUDITED) PRIMECAP ODYSSEY FUNDS PORTFOLIO MANAGERS PRIMECAP Management Company has five portfolio managers who together have more than 150 years of investment experience.

Wayne Smith is the "audit committee financial expert" and is considered to be "independent" as each term is defined in Item 3 of Form N-CSR. ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES. The registrant has engaged its principal accountant to perform audit services, audit-related services, tax services and other services during the past two fiscal years. "Audit services" refer to performing an audit of the registrant's annual financial statements or services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements for those fiscal years. "Audit-related services" refer to the assurance and related services by the principal accountant that are reasonably related to the performance of the audit. "Tax services" refer to professional services rendered by the principal accountant for tax compliance, tax advice, and tax planning. There were no "other services" provided by the principal account. The following table details the aggregate fees billed or expected to be billed for each of the last two fiscal years for audit fees, audit-related fees, tax fees and other fees by the principal accountant. - -------------------------------------------------------------------------------- FYE 10/31/2006 FYE 10/31/2005 - -------------------------------------------------------------------------------- Audit Fees $70,500 $51,175 Audit-Related Fees $0 $0 Tax Fees $13,500 $6,600 All Other Fees $0 $0 - -------------------------------------------------------------------------------- The audit committee has adopted pre-approval policies and procedures that require the audit committee to pre-approve all audit and non-audit services of the registrant, including services provided to any entity affiliated with the registrant. All of the principal accountant's hours spent on auditing the registrant's financial statements were attributed to work performed by full-time permanent employees of the principal accountant. The following table indicates the non-audit fees billed or expected to be billed by the registrant's accountant for services to the registrant and to the registrant's investment adviser (and any other controlling entity, etc.--not sub-adviser) for the last two years. The audit committee of the board of trustees/directors has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser is compatible with maintaining the principal accountant's independence and has concluded that the provision of such non-audit services by the accountant has not compromised the accountant's independence. - -------------------------------------------------------------------------------- Non-Audit Related Fees FYE 10/31/2006 FYE 10/31/2005 - -------------------------------------------------------------------------------- Registrant $13,500 $6,600 Registrant's Investment Adviser $0 $0 - -------------------------------------------------------------------------------- ITEM 5.
