Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920's. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme business slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares have been unjustifiably beaten down by indiscriminate selling, but that nonetheless have strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process is supported by an integrated team approach and results in the careful balance of risk and reward that we apply to each of our portfolios. While we 2 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Global Select Equity Fund | Annual Report | 8/31/08 3 Portfolio Management Discussion | 8/31/08 In the following interview, portfolio manager Piergaetano Iaccarino discusses the factors that influenced performance of the Fund for the annual period ended August 31, 2008. Q How did the Fund perform over the 12-month period ended August 31, 2008? A The Fund's total return from August 31, 2007, through August 31, 2008, was -10.68% (Class A shares at net asset value) versus -11.57% for the MSCI World Index for the same period. While the global environment for equities was volatile during the 12-month period, strong stock selection helped mitigate some of the downside for the Fund's shareholders. Q Can you review the Fund's overall investment approach? A We look at mid- and large-capitalization stocks in more than 30 countries and from that universe build a concentrated portfolio of fewer than 50 stocks. Each stock that we hold will generally be overweighted by at least one percent versus the MSCI World Index. In selecting securities for the portfolio, we look for "growth at a reasonable price," and so there is a strong value component to our analysis. We seek companies that not only are benefiting from operating efficiencies as reflected in things like increased market share and revenues, but that also use their capital efficiently. In particular, we look for strong free cash flow, because this gives a company the flexibility to do things like make share buybacks, reinvest in the business, make acquisitions, and raise dividends. Finally, we assess not only the potential price gains for each stock, but also the potential for a decline in price if things go wrong, and favor those stocks with the highest upside relative to their downside. Q Could you characterize the global equity markets over the period? A Global equity markets were volatile throughout the 12-month period and ended the period lower. Problems in the US subprime mortgage market that emerged in the summer of 2007 precipitated a dramatic shift in investor risk tolerance worldwide. This in turn led to widespread selling across the equity markets, with financial sectors and cyclical companies with exposure to developed markets faring the worst. As the period progressed, significant asset write-offs among global financial companies related to subprime mortgages in the US and tightening credit markets continued to undermine investor confidence. Amid fears that the difficulties would damage the broader economic environment, the US Federal Reserve cut short term rates from 5.25% to 2.00% over the period. In March, in response to the collapse 4 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 of leading investment bank Bear Stearns, the Fed took unprecedented, aggressive steps to provide liquidity to the financial markets The Fed's actions helped to stabilize market sentiment briefly, before an alarming run-up in the price of oil and other commodities heightened investor concerns over both global growth and inflation. The European Central Bank remained focused on inflation, initiating an upward movement in rates toward the end of the period despite the ongoing financial market turbulence. Toward the end of the period, the price of oil eased and the dollar strengthened, providing some relief to the outlook. U.S. equities held up somewhat better over the 12 months than their European and Japanese counterparts, although all three major developed markets saw double digit percentage declines. From a sector perspective, the strongest areas in the global equity markets were materials, information technology and energy stocks, while the weakest returns were among financial issues. Q What strategies or holdings helped and hurt Fund performance over the period? A The Fund outperformed versus its benchmark over the 12 months, driven by a combination of rewarding sector allocations and solid stock selection. In particular, the Fund's overweighting of materials supported returns during the period as the sector outperformed. The main portfolio contributors within the sector were fertilizer manufacturers Yara and Agrium, both of which benefited from an upswing in agricultural activity following higher crop prices. Mining company Rio Tinto also contributed on the back of expectations surrounding the proposed takeover by BHP Billiton. The Fund was also significantly overweight information technology during the period, helping performance. A strong contributor in the sector was Take-Two Interactive, a software developer, whose shares rose sharply after computer games manufacturer Electronic Arts made a bid for the company. The Fund's underweighting of financials proved helpful during the period as ongoing problems in the U.S. subprime mortgage market weighed on the sector. However, within the sector our exposure to banks with subprime exposure such as Citigroup and Societe Generale held back performance. Also within financials, exposure to real estate-related issues Hong Kong-based Henderson Land and Annaly Mortgage Management constrained performance for the full period. The Fund was also underweight industrials during the period, benefiting performance as the sector fared slightly worse than the benchmark. In addition, the Fund's holdings of Flowserve, which produces machinery used in crude oil refining, performed strongly during the period, driven by better-than-expected results. On the negative side of the ledger, the Fund's underweighting of energy kept the Fund from fully realizing the positive impact of higher oil prices on Pioneer Global Select Equity Fund | Annual Report | 8/31/08 5 companies in that sector. Poor stock selection within the consumer discretionary sector, including exposure to Porsche and Adidas, held back returns during the period as consumer confidence remained low. In addition, the Fund's overweighting of pharmaceuticals detracted from returns during the period. In particular, Bristol-Myers Squibb shares lost ground because of the company's exposure to subprime-related securities. AstraZeneca shares also faltered as problems arose with new drugs in the development stages. Finally, the Fund was slightly overweight technology hardware during the period, and the sector's weak performance as well as our stock selection within it constrained performance to a degree. Q What is your outlook and how is it reflected in the Fund's portfolio? A We expect continued equity market volatility in the months ahead. On the whole, we continue to view global equities as an attractive asset class, although the outlook is more moderate than in previous years and the potential risks are greater. The question remains as to what extent global economic growth will be impacted by the ongoing issues in the United States. The adjustment in housing and mortgage-related problems in the financial sector are likely to remain headwinds for the U.S. economy for some time, suggesting that below-trend growth may persist. On the positive side, any continued moderation in the price of crude oil would help support the major economies. In absolute terms, valuations remain a strong point for global equities, which continue to trade at attractive levels versus both government bond yields and long-term equity averages. Going forward, we will remain focused on identifying individual stocks that are reasonably priced and where we have high levels of conviction about the share price upside. Please refer to the Schedule of Investments on pages 15-19 for a full listing of fund securities. Investing in foreign and/or emerging markets securities involves certain risks, including risks relating to interest rates, currency exchange rates, economic, and political conditions. Investments in mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund is non-diversified and invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of funds holding more securities. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. 6 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 Any information in this shareholder report regarding market or economic trends or the factors influencing the Fund's historical or future performance are statements of the opinion of Fund management as of the date of this report.

This example is intended to help you understand your ongoing expenses (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 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Global Select Equity Fund Based on actual returns from March 1, 2008 through August 31, 2008. Share Class A B C Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 3/1/08 - -------------------------------------------------------------------------------- Ending Account $ 910.13 $ 905.69 $ 906.33 Value on 8/31/08 - -------------------------------------------------------------------------------- Expenses Paid $ 6.24 $ 10.54 $ 10.54 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.30%, 2.20% and 2.20% for Class A, Class B and Class C shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one half year period). Pioneer Global Select Equity Fund | Annual Report | 8/31/08 13 Comparing Ongoing Fund Expenses (continued) Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. 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 Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) or redemption fees that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Global Select Equity Fund (the Fund), is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory business trust registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund is non-diversified. The Fund was organized on October 12, 2005, and commenced operations on December 15, 2005. The Fund's investment objective is to seek long-term capital growth. The Fund offers three classes of shares -- Class A, Class B and Class C shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that each class of shares can bear different transfer agent and distribution fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B and Class C shareowners, respectively. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting periods. Actual results could differ from those estimates. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectuses (unaudited) contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: Pioneer Global Select Equity Fund | Annual Report | 8/31/08 27 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued using the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued using the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. The Fund invests primarily in securities of non-U.S. issuers. The principal exchanges and markets for such securities have closing times prior to the close of the NYSE. However, the value of these securities may be influenced by changes in global markets occurring after the closing times of the local exchanges and markets up to the time the Fund determines its net asset value. Consequently, the Board of Trustees of the Fund has determined that the use of daily fair valuations as provided by a pricing service is appropriate for the Fund. The Fund may also take into consideration other significant events in determining the fair value of these securities. Thus, the Fund's securities valuations may differ from prices reported by the various local exchanges and markets. At August 31, 2008, there were no fair valued securities. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. All tax returns filed thus far are open (subject to examination by tax authorities). The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net 28 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At August 31, 2008, the Fund has reclassified $18,728 to increase undistributed net investment income and $18,728 to increase accumulated net realized loss on investments and foreign currency transactions to reflect permanent book/tax differences. The reclassification has no impact on the net asset value of the Fund and is designed to present the Fund's capital accounts on a tax basis. The Fund has elected to defer approximately $133,084 of capital losses recognized between November 1, 2007 and August 31, 2008 to its fiscal year ending August 31, 2009. The tax character of distributions paid during the years ended August 31, 2008 and August 31, 2007 was as follows: 2008 2007 Distributions paid from: Ordinary income $127,503 $53,086 Long-term capital gain 201,886 -- - -------------------------------------------------------------------------------- Total $329,389 $53,086 ================================================================================ The following shows the components of distributable earnings on a federal income tax basis at August 31, 2008: 2008 Distributable Earnings: Undistributed ordinary income $ 58,580 Post-October loss deferred (133,084) Unrealized depreciation (514,044) - -------------------------------------------------------------------------------- Total $ (588,548) ================================================================================ The difference between book basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $1,770 in underwriting commissions on the sale of Class A shares during the year ended August 31, 2008. D. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using Pioneer Global Select Equity Fund | Annual Report | 8/31/08 29 current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the statement of operations from the effects of changes in market price of those securities but are included with the net realized and unrealized gain or loss on investments. E. Forward Foreign Currency Contracts The Fund enters into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date as a hedge or cross-hedge against either specific investment transactions (settlement hedges) or portfolio positions (portfolio hedges). All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar. At August 31, 2008, the Fund had no outstanding portfolio or settlement hedges. F. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B and Class C shares of the Fund, respectively (see Note 4). Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, and in the same amount, except that Class A, Class B and Class C shares can bear different transfer agent and distribution expense rates. G. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors, with the Fund's custodian acting as the lending agent. 30 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 When entering into a loan, the Fund receives collateral, which is maintained by the custodian and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The loans are secured by collateral which is required to be at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in cash equivalent investments. Securities lending collateral is managed by Credit Suisse. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.75% of the Fund's average daily net assets up to $500 million; 0.70% of the next $500 million and 0.65% of the excess over $1 billion. For the year ended August 31, 2008, the effective management fee (net of waivers and/or assumption of expense) was equivalent to 0.75% of the Fund's average net assets. PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit the Fund's expenses to 1.30%, 2.20% and 2.20% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. These expense limitations are in effect through January 1, 2011 for Class A and through January 1, 2009 for Class B and Class C shares. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $331 in management fees, administrative costs and certain other services payable to PIM at August 31, 2008. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,742 in transfer agent fees payable to PIMSS at August 31, 2008. 4. Distribution Plans and Service Plans The Fund adopted a Plan of Distribution with respect to Class A, Class B and Class C shares in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily Pioneer Global Select Equity Fund | Annual Report | 8/31/08 31 net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Prior to February 1, 2008, PFD was reimbursed under the Plan of Distribution for distribution expenses in an amount of up to 0.25% of the average daily net assets attributable to Class A shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $245 in distribution fees payable to PFD at August 31, 2008. In addition, redemptions of each class of shares may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase. Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.00% based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00% based on the lower of cost or market value of shares being redeemed. Proceeds from the CDSCs are paid to PFD. For the year ended August 31, 2008, CDSCs in the amount of $930 were paid to PFD. 5. Expense Offsets Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended August 31, 2008, the Fund's expenses were reduced by $441 under such arrangements. 6. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. 32 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 Report of Independent Registered Public Accounting Firm To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Global Select Equity Fund: - -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Global Select Equity Fund (the Fund) (one of the portfolios constituting Pioneer Series Trust V), including the schedule of investments, as of August 31, 2008, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits 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 and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2008, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Global Select Equity Fund at August 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts October 20, 2008 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 33 ADDITIONAL INFORMATION (unaudited) For the year ended August 31, 2008, certain dividends paid by the Fund may be subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax Relief Reconciliation Act (the Act) of 2003.

Complete information will be computed and reported in conjunction with your 2008 form 1099-DIV. The qualifying percentage of the Fund's ordinary income dividends for the purpose of the corporate dividends received deduction was 27.91%. The percentages of the Fund's ordinary income distributions that are exempt from nonresident alien (NRA) tax withholding resulting from qualified interest income and qualified short term gains were 0% and 59.52%, respectively.

Pioneer Global Select Equity Fund | Annual Report | 8/31/08 35 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine annually whether to continue the investment advisory agreement for the Fund. In connection with their most recent consideration of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 13, 2007, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the continuation of the investment advisory agreement for another year. At a meeting held on January 8, 2008, the Trustees considered whether an amended and restated investment advisory agreement for the Fund should be approved for an initial period ending December 31, 2009. The management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement is the same as the management fee provided in the previously approved investment advisory agreement. Based on their evaluation of the information provided by PIM, including the information provided by PIM in connection with the Trustees' most recent approval of the continuation of the previous investment advisory agreement, the Trustees, including the independent Trustees voting separately, unanimously approved the amended and restated investment advisory agreement. Shareholders of the Fund approved the amended and restated investment advisory agreement at a meeting held on May 13, 2008. In considering the amended and restated investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the amended and restated investment advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that were provided by PIM to the Fund under the previous investment advisory agreement, and that would continue to be provided by PIM to the Fund under the amended and restated investment advisory agreement, taking into account the investment objective and strategy of the Fund and the information related to 36 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the amended and restated investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provided under the previous investment advisory agreement and that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement, were satisfactory and consistent with the terms of the amended and restated investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees noted that the Fund commenced operations on December 15, 2005. They considered that the Fund's annualized total return was in the third quintile of its Morningstar category for the one year period ended June 30, 2007 and that the Fund's total return for 2006 was in the second quintile of its Morningstar category. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered that the management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement would be the same as the management fee to be paid by the Fund under the previously approved investment advisory agreement. The Trustees considered information on the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense Pioneer Global Select Equity Fund | Annual Report | 8/31/08 37 ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2007 was in the second quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2007 was in the first quintile relative to its Strategic Insight peer group. It was noted that PIM did not currently manage any accounts with an investment objective and strategies that were similar to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the size of the Fund, the quality of services provided by PIM, the investment performance of the Fund and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that PIM should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. The Trustees concluded that, because of the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. 38 Pioneer Global Select Equity Fund | Annual Report | 8/31/08 Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds and the benefits to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees further considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the terms of the amended and restated investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the amended and restated investment advisory agreement for the Fund.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920's. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme business slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares have been unjustifiably beaten down by indiscriminate selling, but that nonetheless have strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process is supported by an integrated team approach and results in the careful balance of risk and reward that we apply to each of our portfolios. While we 2 Pioneer High Income Municipal Fund | Annual Report | 8/31/08 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer High Income Municipal Fund | Annual Report | 8/31/08 3 Portfolio Management Discussion | 8/31/08 Over the 12 months ending August 31, 2008, municipal bond investors weathered one of the most turbulent periods in history, as fallout from problems in the subprime mortgage sector reverberated throughout the fixed-income markets. In the following interview, portfolio manager Timothy Pynchon discusses the factors that affected the municipal bond market and the Fund over the period. Q How did the Fund perform during the 12-month period ended August 31, 2008? A For the 12-month period ended August 31, 2008, Pioneer High Income Municipal Fund's Class A shares produced a total return of -4.95% at net asset value. For the same period, the Fund's benchmark, the Lehman Brothers High Yield Municipal Bond Index returned -4.37%; and the average return of the 104 funds in the Lipper High Yield Municipal Debt Funds category was -3.14%. The Fund's Class A shares generated a 30-day SEC tax-free yield of 6.36%, based on the maximum income tax rate of 35%. On August 31, 2008, the Fund's current yield was 6.48%, which translates into a taxable yield of 9.78%. At the end of the period, the Fund had 53 issues in 25 states. The average credit quality of the portfolio was BBB-. Q What was the investment environment like during the period? A It was a challenging investment environment, as a confluence of events caused municipal bonds to decline. Early in the period, the credit markets began to feel the effects of the emerging problems in the subprime mortgage market. In late 2007 and early 2008, investors began selling the lower quality securities. Hedge funds were particularly large sellers, as they unwound their municipal bond positions and flooded the market with hundreds of millions of dollars of municipal debt, creating a huge supply/ demand imbalance. In the face of all this, in February, three of the largest bond insurers -- Financial Guarantee Insurance Company (FGIC), Municipal Bond Insurance Association (MBIA), and Ambac Financial Group (AMBAC) -- fell into financial distress because they had insured structured mortgage products that were tied to defaulting subprime mortgages, causing all three insurers to lose their AAA credit ratings. At about the same time, investment banks refused to support auctions for auction-rate securities, which are long-term bonds tied to short-term interest rates that are set at weekly or monthly auctions. As a result, investors saw the auction market and liquidity freeze up. 4 Pioneer High Income Municipal Fund | Annual Report | 8/31/08 In this environment, investors sought quality above everything else and fled to the Treasury market as a safe haven. The result was that municipal bond yields rose above Treasury yields, even before reflecting the tax-exempt effect. Investors could buy tax-exempt municipal bonds at nearly a full percentage point more than Treasuries -- a situation that has been relatively rare over the past three decades. During the month of February, long-term AAA bonds were yielding 5.14% compared to Treasury bond yields of 4.40%, a ratio of 117%; 10-year municipal bonds were at 4.12% compared to Treasuries at 3.51%, a ratio of 117%; five-year municipal yields were at 3.30% compared to Treasuries at 2.48%, a ratio of 133%. Eight months earlier, these ratios had been: 30 years 87%, 10 years 81%, and 5 years 79%, respectively. Rising bond yields pushed prices down; and as valuations became more compelling, investors returned to the municipal bond market, which began to recover in March. By the end of July, the average monthly ratios of the 10- and 30-year AAA municipal bonds were 98% and 105%, respectively. Q How did you manage the Fund in this environment? A We did not make any big changes to the Fund's portfolio during the period. The Fund was well diversified among sectors that are vital to the U.S. economy. These included health care (32% of net assets), education (6% of net assets), pollution control (3% of net assets), transportation (3% of net assets), water and sewer (2% of net assets), housing (2% of net assets). About 15% of the Fund's net assets were in tobacco bonds as of August 31, 2008, which are backed by tobacco companies' payments to states as part of the Master Settlement Agreement in which states agreed to drop their lawsuits against tobacco companies in return for a series of payments. Nearly all of the Fund's assets were invested in revenue bonds on which the payment of interest and principal is derived from the revenues generated by the particular asset the bond was issued to finance. Because revenue bonds do not depend on the taxing power of the state, they tend to hold their value when the economy is weak and revenues going into state coffers may decline. Q What affected performance during the period? A As stated above, the Fund slightly underperformed its benchmark, the Lehman Brothers High Yield Municipal Bond Index, during the period. The performance of the Fund and its benchmark during the period reflect the general turmoil in the municipal bond market and the flight to quality that took place over the 12-month period, as market participants avoided the riskiest investments and moved into Treasuries. The Fund's relatively long duration in a volatile market also held back results. (Duration measures a bond's price sensitivity to interest-rate changes. A shorter duration can minimize a bond's price fluctuations.) As high-yield investors, we believe Pioneer High Income Municipal Fund | Annual Report | 8/31/08 5 the best potential for total return going forward is in the longer end of the market; and, in the short term, we are willing to take on the slightly more downside risk that comes from a longer duration, in anticipation of bigger upside potential over the longer term. Airline bonds, which accounted for about 5% of the Fund's total net assets at August 31, 2008, were disappointing, as the airline industry suffered because of higher jet fuel costs resulting from rising oil prices. Tobacco bonds during the period also fell short of our expectations. The poor performance of tobacco bonds resulted from concerns by some investors that a decline in smoking in the United States would result in lower revenues for tobacco companies. We disagree with this belief, and the tobacco bonds remain in the portfolio. Q What is your outlook? A We believe there is exceptional value in the municipal market and are taking advantage of the higher yields and lower prices that municipals provide. Longer-term municipal bonds currently offer higher tax-free yields than A-rated taxable corporate bonds. As we look ahead, we believe municipal bonds will continue to provide investors with a relatively high level of tax-free income and the potential for price appreciation. Please refer to the Schedule of Investments on pages 15-19 for a full listing of Fund securities. Investments in high-yield or lower-rated securities are subject to greater-than-average risk. The Fund may invest in securities of issuers that are in default or that are in bankruptcy. A portion of the income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. The fund is not diversified, which means that it can invest a higher percentage of its assets in any one issuer than a diversified fund. Being non-diversified may magnify the fund's losses from adverse events affecting a particular issuer. By investing primarily in municipal securities, the portfolio is more susceptible to adverse economic, political or regulatory developments than is a portfolio that invests more broadly. Investments in the Fund are subject to possible loss due to financial failure of underlying securities and their inability to meet their debt obligations. When interest rates rise, the prices of fixed-income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities in the Fund will generally rise. Investments in the Fund are subject to possible loss due to the financial failure of issuers of underlying securities and their inability to meet their debt obligations. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. 6 Pioneer High Income Municipal Fund | Annual Report | 8/31/08 Past performance is not a guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

This example is intended to help you understand your ongoing expenses (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 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: 1. Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 2. Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer High Income Municipal Fund Based on actual returns from March 1, 2008 through August 31, 2008. - -------------------------------------------------------------------- Share Class A C Y - -------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 3/1/08 - -------------------------------------------------------------------- Ending Account $ 1,026.53 $ 1,022.95 $ 1,026.27 Value on 8/31/08 - -------------------------------------------------------------------- Expenses Paid $ 4.58 $ 9.15 $ 5.04 During Period* - -------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 0.90%, 1.80% and 0.99% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the half year period). Pioneer High Income Municipal Fund | Annual Report | 8/31/08 13 Comparing Ongoing Fund Expenses (continued) Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. 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 Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer High Income Municipal Fund (the Fund) is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund is non-diversified. The Fund commenced operations on October 17, 2006. The investment objective of the Fund is to maximize total return through a combination of income that is exempt from regular federal income tax and capital appreciation. The Fund offers three classes of shares designated as Class A, Class C, and Class Y shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidations, except that each class of shares can bear different transfer agent and distribution fees and has exclusive voting rights with respect to the distribution plan that has been adopted by Class A and Class C shareowners, respectively. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses, and gain or loss on investments during the reporting period. Actual results could differ from those estimates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The fund's prospectuses (unaudited) contain information regarding the fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements which, are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Securities are valued at prices supplied by independent pricing services, which Pioneer High Income Municipal Fund | Annual Report | 8/31/08 27 consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which there are no other readily available market quotations are valued at their fair values as determined by, or under the direction of the Board of Trustees. At August 31, 2008, there were no securities fair valued. Temporary cash investments are valued at cost which approximates market value. Discount and premium on debt securities are accreted or amortized, respectively, daily into interest income on a yield-to-maturity basis with a corresponding increase or decrease in the cost basis of the security. Interest income is recorded on the accrual basis. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income, exempt interest income, and net realized capital gains, if any, to its shareowners. Therefore, no federal tax provision is required. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At August 31, 2008, the Fund had a net capital loss carryforward of $667,588 which will expire in 2016 if not utilized. The Fund has elected to defer approximately $1,420,432 of capital losses recognized between November 1, 2007 and August 31, 2008 to its fiscal year ending August 31, 2009. At August 31, 2008, the Fund has reclassified $3,164 to increase distributions in excess of net investment income and $3,164 to decrease accumulated net realized loss on investments, to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax basis. 28 Pioneer High Income Municipal Fund | Annual Report | 8/31/08 The tax character of distributions paid during the years ended August 31, 2008, and August 31, 2007 was as follows: -------------------------------------------------------- 2008 2007 -------------------------------------------------------- Distributions paid from: Tax-exempt income $2,433,183 $433,538 Ordinary income -- 38 -------------------------------------------------------- Total $2,433,183 $433,576 ======================================================== The following shows the components of distributable earnings on a federal income tax basis at August 31, 2008: ------------------------------------------------------------ 2008 ------------------------------------------------------------ Distributable earnings: Undistributed tax-exempt income $ 300,343 Capital loss carryforward (667,588) Current year dividend payable (239,830) Current year post-October loss deferral (1,420,432) Unrealized depreciation (4,191,043) ------------------------------------------------------------ Total $ (6,218,550) ============================================================ The difference between book-basis and tax-basis unrealized depreciation is attributable to the tax basis adjustments on partnerships, the tax treatment of premium and amortization and interest on defaulted bonds. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A., (UniCredit), earned $37,369 in underwriting commissions on the sale of Class A shares during the year ended August 31, 2008. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Pioneer High Income Municipal Fund | Annual Report | 8/31/08 29 The Fund declares, as daily dividends, substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, and in the same amount, except that Class A, Class C, and Class Y shares can bear different transfer agent and distribution expense rates. 2. Management Agreement Pioneer Investment Management, Inc., (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.50% of the Fund's average daily net assets up to $500 million; 0.475% of the next $500 million; and 0.45% of the excess over $1 billion. For the year ended August 31, 2008, the effective management fee (net of waivers and/or assumption of expenses) was equivalent to 0.50% of the Fund's average net assets. PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses (excluding taxes, commissions, interest and extraordinary expenses) of the Fund to the extent necessary to limit expenses to 0.90% and 1.80% of the average daily net assets attributable to Class A shares and Class C shares, respectively. The Class A limitation is in effect through January 1, 2011 and the Class C limitation is in effect through January 1, 2009. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund. Included in "Due to Affiliates" reflected on the Statement of Assets and Liabilities is $2,600 in management fees, administrative costs and certain other services payable to PIM at August 31, 2008. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareholder services to the Fund at negotiated rates. Included in "Due to Affiliates" reflected in the Statement of Assets and Liabilities is $3,229 in transfer agent fees payable from PIMSS at August 31, 2008. 4. Distribution Plans The Fund adopted a Plan of Distribution for each class of shares (Class A Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment Company Act of 1940. Effective February 1, 2008, under the Class A Plan, the Fund pays PFD a service fee equal to 0.25% of the average daily net assets attributable to Class A shares to finance activities primarily intended to result in the sale of Class A shares. Prior to February 1, 2008, PFD was reimbursed for service fees 30 Pioneer High Income Municipal Fund | Annual Report | 8/31/08 in an amount up to 0.25% of the average daily net assets attributable to Class A shares. Pursuant to the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Included in "Due to Affiliates" reflected on the Statement of Assets and Liabilities is $2,501 in distribution fees payable to PFD at August 31, 2008. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. There is no CDSC for Class Y shares. For the year ended August 31, 2008, CDSCs in the amount of $16,888 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended August 31, 2008, the Fund's expenses were reduced by $305 under such arrangements. 6. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures.

(PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine annually whether to continue the investment advisory agreement for the Fund. In connection with their most recent consideration of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 13, 2007, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the continuation of the investment advisory agreement for another year. At a meeting held on January 8, 2008, the Trustees considered whether an amended and restated investment advisory agreement for the Fund should be approved for an initial period ending December 31, 2009. The management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement is the same as the management fee provided in the previously approved investment advisory agreement. Based on their evaluation of the information provided by PIM, including the information provided by PIM in connection with the Trustees' most recent approval of the continuation of the previous investment advisory agreement, the Trustees, including the independent Trustees voting separately, unanimously approved the amended and restated investment advisory agreement. Shareholders of the Fund approved the amended and restated investment advisory agreement at a meeting held on May 13, 2008. In considering the amended and restated investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the amended and restated investment advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that were provided by PIM to the Fund under the previous investment advisory agreement, and that would continue to be provided by PIM to the Fund under the amended and restated investment advisory agreement, taking into account the investment objective and strategy of the Fund and the information related to Pioneer High Income Municipal Fund | Annual Report | 8/31/08 35 the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the amended and restated investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provided under the previous investment advisory agreement and that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement, were satisfactory and consistent with the terms of the amended and restated investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees noted that the Fund commenced operations on October 16, 2006. They considered that the Fund's performance for the period from January 1, 2007 through June 30, 2007 was in the third quintile of its Morningstar category. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered that the management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement would be the same as the management fee to be paid by the Fund under the previously approved investment advisory agreement. The Trustees considered information on the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by 36 Pioneer High Income Municipal Fund | Annual Report | 8/31/08 the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2007 was in the third quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2007 was in the first quintile relative to its Strategic Insight peer group. It was noted that PIM did not currently manage any accounts with an investment objective and strategies that were similar to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the size of the Fund, the quality of services provided by PIM, the investment performance of the Fund and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that PIM should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. The Trustees concluded that, because of the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. Pioneer High Income Municipal Fund | Annual Report | 8/31/08 37 Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds and the benefits to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees further considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the terms of the amended and restated investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the amended and restated investment advisory agreement for the Fund. 38 Pioneer High Income Municipal Fund | Annual Report | 8/31/08 Trustees, Officers and Service Providers Investment Adviser Pioneer Investment Management, Inc.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920's. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme business slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares have been unjustifiably beaten down by indiscriminate selling, but that nonetheless have strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process is supported by an integrated team approach and results in the careful balance of risk and reward that we apply to each of our portfolios. While we 2 Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 3 Portfolio Management Discussion | 8/31/08 In the following interview, Robert McVicker, Pioneer Oak Ridge All Cap Growth Fund's lead portfolio manager, discusses the factors that influenced performance during the annual period ended August 31, 2008. Q How did the U.S. stock market perform during the past year ended August 31, 2008, and how did this affect the Fund? A A litany of negative factors combined to dampen investor sentiment during the past year, leading to very poor performance for the U.S. stock market. The leading cause of the downturn was the ongoing fallout from the housing crisis, which led to a freezing of the credit markets and widespread concerns about the health of financial institutions' balance sheets. Stocks were also pressured by slowing economic growth and rising inflation, the combination of which pinched corporate profit margins and dampened the earnings outlook for U.S. companies. In this environment, financial, real estate, and consumer shares all performed poorly. At the same time, stocks with the greatest exposure to rising prices for oil and other commodities -- most notably those in the energy and materials sectors -- generally outperformed. In a reflection of the challenging market conditions, the Class A shares of the Fund returned -7.15% at net asset value during the 12-month period ended August 31, 2008, trailing the -6.56% return of its benchmark, the Russell 3000 Growth Index (the Russell Index), over the same period. Although the Fund underperformed in the short term, we believe it is well- positioned for the environment we see unfolding in the months ahead. This is discussed in greater detail below. Q Where did the Fund deliver the best performance over the 12 months ended August 31, 2008? A Although the Fund underperformed, there were a number of areas in which we added substantial value to its portfolio. Foremost among these areas was the energy sector, a group that surged during the first nine months of the period, only to endure a significant correction thereafter. Still, the Fund's positions in Southwestern Energy, XTO Energy, and the energy services company Schlumberger, all made contributions to the Fund's performance during the full period. Despite the downturn in energy near the end of the 12-month period, we remain positive on the longer-term outlook for the sector. As the economies of the developing world mature, the demand for energy continues to increase at a faster rate than the growth in available supply. The result, in 4 Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 our view, is that the recent correction in the energy sector has created bargains for those with a long-term investment horizon. For example, we increased the Fund's position of shares in Schlumberger when it fell about 20% off its 2008 high. Energy companies have been buying up land at a rapid pace in recent years, and the need to explore and drill these properties, in our opinion, should lead to a steady increase in the demand for the types of services provided by Schlumberger. We also used the downturn in energy stocks to initiate a small position for the Fund in Petrohawk Energy, a smaller exploration and production company whose shares fell to the $27 range in mid-August, after trading at near $55 a month earlier. We believe Petrohawk's properties in the Haynesville Shale area of northwestern Louisiana have tremendous upside potential. Thus, the sharp sell-off in the stock's price presented an attractive opportunity for us to establish a position for the Fund. Overall, we have been focusing on companies that we believe have favorable prospects for superior growth in earnings, production, and proven reserves. We believe this puts the Fund in a strong position to outperform the energy sector over the longer term, regardless of shorter-term fluctuations in the price of oil and natural gas. Q In what other sectors did you add value to the Fund's portfolio during the 12-month period? A We are pleased to report that at a time when financial stocks registered exceptionally poor performance, the Fund avoided the worst of the downturn because of management's decision to avoid investments in bank and brokerage stocks. Our approach has been to focus the Fund's resources on the "haves" in the sector -- companies with stable earnings, strong balance sheets, and no exposure to the mortgage crisis -- and to avoid the "have-nots." This strategy led us to invest the Fund in companies such as Charles Schwab and Affiliated Managers Group, both of which benefit from recurring fee income and have maintained their financial strength throughout the turmoil of the past year. The Fund's underweight in the materials sector also added value as the fiscal year progressed. During the first half of the period, the Fund's performance was hurt by the fact that the portfolio did not own any of the cyclical materials companies that were among the market's leaders, such as those in the steel, coal, and farming sectors. Such companies tend to have volatile earnings results, which does not fit our preference for stable growers. Once these stocks began to correct during the second half of the period, the Fund's lack of investment in this area became a positive factor in its performance. Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 5 Finally, we added value to the Fund during the period in the health care sector, via an emphasis on biotechnology stocks and a corresponding underweight in large pharmaceutical companies. The latter group is beset by drug patent expirations and weak pipelines of new drugs, reducing the reliability of earnings. The opposite is true in biotech, yet many stocks have traded at extremely attractive valuation levels in recent years. This led us to invest the Fund in biotech stocks such as Genentech, Celgene, and Gilead Sciences, all of which performed well during the past year. Q What were some areas in which the Fund underperformed during the 12-month period? A The Fund's worst area was the consumer discretionary sector, the segment of the market most affected by consumers' need to reduce spending at a time of slower economic growth and rising prices for staples such as food and gasoline. The Fund's two worst performers included one of its long-term winners, Marriott, as well as a newer holding, Abercrombie & Fitch. Marriott was hurt as both consumers and businesses cut back on travel at a time when rising fuel costs have made travelling a more expensive proposition. Abercrombie, meanwhile, was a stock added to the portfolio earlier in 2008 based on the company's strong earnings growth, capable management, and exposure to the typically recession-resistant teen demographic. The stock has proven less resilient than we expected, however, due to higher than expected expenditures and disappointing same-store sales results. Believing that our original investment thesis was no longer valid, we elected to sell the position from the Fund. The technology sector was also a source of underperformance for the Fund. Here, investor fears about slowing economic growth caused a number of large-cap tech stocks to lose substantial ground, despite their solid fundamentals. Most notable among that group were Google, Apple, Microsoft, Intel, Hewlett Packard, and Cisco Systems. We believed all of these classic growth leaders represented compelling investments at the time we added them to the Fund, and we think this remains all the more true following their poor performance so far in 2008. In fact, Microsoft, Intel, Cisco and Hewlett Packard have been trading at less than the market price-to-earnings (P/E) ratio despite their superior earnings prospects. Q What is your broader view on the U.S. stock market? A We don't believe in market timing. Rather, we believe it is impossible to predict consistently the direction of the stock market. Throughout history, and on several occasions this year, many apparent market bottoms have instead turned into trap doors. Nevertheless, we feel the market will eventually bottom and stocks will be poised to move higher. While stocks may remain under near-term pressure due to the uncertainty regarding economic growth and the health of financial companies, the downturn of the past year 6 Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 has created a wealth of opportunities for long-term investors. In fact, many quality growth stocks have fallen to valuations where their P/E ratios are near their long-term growth rates, a measure that we use to help identify attractive growth stock opportunities for the Fund. With this as background, we have used the market volatility of the past 12 months to add new positions to the Fund and to increase its weighting in stocks whose valuations have fallen despite their strong underlying fundamentals. Overall, our focus continues to be on companies with strong fundamentals that have proven their ability to grow earnings despite the challenging economic environment. Current stock valuations have only strengthened our conviction about the favorable/risk reward profile of the portfolio, and we remain optimistic about the long-term outlook for the Fund.

You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Oak Ridge All Cap Growth Fund Based on actual returns from March 1, 2008 through August 31, 2008. Share Class A C Y Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 3/1/08 - ---------------------------------------------------------------------- Ending Account $ 1,006.72 $ 1,000.98 $ 1,007.79 Value on 8/31/08 - ---------------------------------------------------------------------- Expenses Paid $ 6.31 $ 10.81 $ 5.20 During Period* - ---------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2,15%, and 1.03%, for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 13 Comparing Ongoing Fund Expenses (continued) Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. 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 Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Oak Ridge All Cap Growth Fund (the Fund) is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is capital appreciation. The Fund offers three classes of shares -- Class A, Class C and Class Y shares. Class A, Class C and Class Y shares were first publicly offered on October 17, 2006. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that the level of transfer agent and distribution fees may differ among classes. Class A and Class C shareowners have exclusive voting rights with respect to the distribution plan for each class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectuses (unaudited) contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 27 date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use the fair value of a security, including a non-U.S. security, when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. At August 31, 2008, there were no securities fair valued. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Dividend and interest income is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. All tax provisions filed thus far are open (subject to examination by tax authorities). The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At August 31, 2008, The fund had a net capital loss carryforward of $4,469, which will expire in 2016 if not utilized. The Fund has elected to defer $180,436 of capital losses recognized between November 1, 2007 and August 31, 2008 to its fiscal year ending August 31, 2009. At August 31, 2008, the Fund has reclassified $23,185 to decrease accumulated net investment loss and $23,185 to decrease paid-in capital, to reflect 28 Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax basis. There were no distributions paid during the years ended August 31, 2008 and August 31, 2007. The following shows the components of distributable earnings on a federal income tax basis at August 31, 2008: 2008 Distributable earnings: Capital loss carryforward $ (4,469) Current year post October loss deferred (180,436) Unrealized depreciation (72,577) - ------------------------------------------------------------------------------- Total $ (257,482) =============================================================================== The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned approximately $4,927 in underwriting commissions on the sale of Class A shares during the year ended August 31, 2008. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, on the same day, and in the same amount, except that Class A, Class C, and Class Y shares bear different transfer agent and distribution expense rates. Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 29 E. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a loan, the Fund receives collateral and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The loans are secured by collateral which is required to be at least 102%, at all times, of the fair value of the securities loaned. The amount of collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreement to recover the securities from the borrower on demand. The fund invests cash collateral in cash equivalent investments. Security lending collateral is managed by Credit Suisse, Inc. 2. Management Agreement PIM, a wholly owned subsidiary of UniCredit, manages the Fund's portfolio. PIM receives a basic fee that is calculated at the annual rate of 0.75% of the Fund's average daily net assets up to $500 million; and 0.70% on assets over $500 million. The management fees were equivalent to 0.75% of the average daily net assets for the year ended August 31, 2008. Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.25% and 2.15% of the average daily net assets attributable to Class A and Class C shares, respectively. These expense limitations are in effect through January 1, 2011 for Class A shares and through January 1, 2009 for Class C shares. Effective January 1, 2008, Pioneer has contractually agreed to limit Class Y expenses to 0.95% of the average daily net assets attributable to Class Y shares. This expense limitation is in effect through January 1, 2009. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $436 in management fees, administrative costs, and certain other services payable to PIM at August 31, 2008. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,548 in transfer agent fees payable to PIMSS at August 31, 2008. 30 Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 4. Distribution Plans The Fund adopted a Plan of Distribution for Class A and Class C shares (Class A Plan, and Class C Plan) in accordance with Rule 12b-1 under the Investment Company Act of 1940. Effective February 1, 2008, under the Class A Plan, the Fund pays PFD a service fee equal to 0.25% of the average daily net assets attributable to Class A shares to finance activities primarily intended to result in the sale of Class A shares. Prior to February 1, 2008, PFD was reimbursed for service fees in an amount up to 0.25% of the average daily net assets attributable to Class A shares. Pursuant to the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $206 in distribution fees payable to PFD at August 31, 2008. In addition, redemptions of Class A and Class C shares may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the year ended August 31, 2008, CDSCs in the amount of $34 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into an expense offset arrangement with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended August 31, 2008, the Fund's expenses were reduced by $207 under such arrangements. 6. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures.

An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2008, by correspondence with the custodian and brokers.

(PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine annually whether to continue the investment advisory agreement for the Fund. In connection with their most recent consideration of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 13, 2007, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the continuation of the investment advisory agreement for another year. At a meeting held on January 8, 2008, the Trustees considered whether an amended and restated investment advisory agreement for the Fund should be approved for an initial period ending December 31, 2009. The management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement is the same as the management fee provided in the previously approved investment advisory agreement. Based on their evaluation of the information provided by PIM, including the information provided by PIM in connection with the Trustees' most recent approval of the continuation of the previous investment advisory agreement, the Trustees, including the independent Trustees voting separately, unanimously approved the amended and restated investment advisory agreement. Shareholders of the Fund approved the amended and restated investment advisory agreement at a meeting held on May 13, 2008. In considering the amended and restated investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the amended and restated investment advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that were provided by PIM to the Fund under the previous investment advisory agreement, and that would continue to be provided by PIM to the Fund under the amended and restated investment advisory agreement, taking into account the investment objective and strategy of the Fund and the information related to Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 35 the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the amended and restated investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provided under the previous investment advisory agreement and that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement, were satisfactory and consistent with the terms of the amended and restated investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees noted that the Fund commenced operations on October 16, 2006. They considered that the Fund's performance for the period from January 1, 2007 through June 30, 2007 was in the third quintile of its Morningstar category. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered that the management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement would be the same as the management fee to be paid by the Fund under the previously approved investment advisory agreement. The Trustees considered information on the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by 36 Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2007 was in the third quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2007 was in the first quintile relative to its Strategic Insight peer group. It was noted that PIM did not currently manage any accounts with an investment objective and strategies that were similar to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the size of the Fund, the quality of services provided by PIM, the investment performance of the Fund and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that PIM should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. The Trustees concluded that, because of the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 37 Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds and the benefits to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees further considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the terms of the amended and restated investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the amended and restated investment advisory agreement for the Fund. 38 Pioneer Oak Ridge All Cap Growth Fund | Annual Report | 8/31/08 Trustees, Officers and Service Providers Investment Adviser Pioneer Investment Management, Inc.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920's. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme business slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares have been unjustifiably beaten down by indiscriminate selling, but that nonetheless have strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process is supported by an integrated team approach and results in the careful balance of risk and reward that we apply to each of our portfolios. While we see potential chances for making money in many corners of the market, it 2 Pioneer Research Growth Fund | Annual Report | 8/31/08 takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Respectfully, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Research Growth Fund | Annual Report | 8/31/08 3 Portfolio Management Discussion | 8/31/08 Driven by growing fears about the effects of a global credit crisis that began with problems over U.S. subprime mortgages, prices of most domestic stocks fell over the 12 months ended August 31, 2008. In a highly volatile market, energy stocks showed the greatest positive performance, while financials stocks tended to suffer the greatest price losses. In the following discussion, members of the team responsible for managing Pioneer Research Growth Fund review the 12-month period ended August 31. Diego Franzin, Ashesh Savla and John Peckham, CFA, discuss the factors that affected the Fund's performance over the period. Mr. Franzin is Head of Pioneer's U.S. Quantitative Research & Management; Mr. Savla is a Quantitative Analyst at Pioneer; and Mr. Peckham is Head of Pioneer's U.S. Equity Research Group. Q How did Pioneer Research Growth Fund perform during the 12 months ended August 31, 2008? A Research Growth Fund's Class A shares returned -10.03% at net asset value over the period, while the Fund's benchmark, the Russell 1000 Growth Index (the Russell Index), returned -6.77% over the same period. During the same 12-month period, the average return of the 815 funds in Lipper's Multi-Cap Core Funds category was -10.81%. Q What were the principal factors affecting the Fund's performance during the 12 months ended August 31, 2008? A The deepening global credit crisis arising from problems in the domestic subprime mortgage area created significant uncertainty in the minds of investors, contributing to extreme volatility in the markets. The two most volatile sectors in the market were the financials group, where stock prices fell for the many companies directly exposed to credit problems, and the energy group, where prices of many companies rose because of the effects of rapidly rising oil and natural gas prices. The changes in stock prices in those two sectors contributed most of the volatility to the overall market. It was an unusual period in which technical factors, such as the flow of funds, had a greater influence on the markets than did fundamental issues, such as the underlying quality and profitability of individual companies. Investors often based their decisions on their expectations of policy changes by the U.S. Federal Reserve Board (the Fed), the nation's central bank. The Fed was pulled in two different directions as it considered adjustments in monetary policy -- the need to cut interest rates to add financial liquidity to the financial markets -- against the need to raise interest rates to stave off the inflationary effects of rising energy and commodity prices. While the overall market sentiment was bearish, with stock prices falling, the period also was 4 Pioneer Research Growth Fund | Annual Report | 8/31/08 unusual in that growth stocks tended to outperform value stocks. Typically, growth stocks tend to outperform in bull markets when stock prices are rising, while value stocks have often outperformed in bear markets. Consistent with the investment style of the Fund, stock selection had the greatest influence on performance relative to the performance of the benchmark Russell Index. We kept the sector weightings of the Fund consistent with the positioning of the Russell Index. The approximately 50 stocks in the portfolio included both growth and value companies, and were selected using both qualitative research techniques and quantitative analysis tools. We began by ranking the 100 stocks, according to Pioneer's research analysts, with a quantitative screening process that we developed based upon our research into the performance of stocks in 17 different sectors and industries. We then made final selections based on the fundamental analysis research of Pioneer's Equity Research Group. In a volatile market, we focused on higher-quality companies that had strong balance sheets and relatively low debt, and so the Fund was not greatly exposed to the problems in the credit markets. Q What types of investments most influenced the Fund's results during the 12-month period? A Stock selections in the consumer discretionary and energy sectors had the greatest positive influence on the Fund's results. Within the consumer discretionary group, fast food chain McDonald's was the outstanding performer, with its results driven by its growth in international markets. In the energy sector, Apache, Weatherford International and Hess all benefited from the effects of rising oil and natural gas prices. Apache is a global oil and gas exploration and production company. Weatherford International, an oil field services corporation, prospered as it continued to expand internationally. We sold at a profit the Fund's position in Hess, an integrated exploration, production, refining and marketing company, after its stock appreciated significantly. Among other contributors, Burlington Northern Santa Fe added to the Fund's returns as railroads gained market share from trucking in long-distance freight hauling. The rapidly rising price of diesel fuel was a major factor in eroding the competitiveness of big trucks and increasing the attractiveness of shipping freight by rail. Stocks in the financials sector tended to be the greatest drag on the Fund's performance, with selections in information technology also detracting from results. Among financials holdings, First Marblehead was a significant disappointment. The company, which specializes in securitizing student loans, was hurt when the market for securitized loans dried up in the credit crisis. We sold the Fund's position in First Marblehead because we thought no improvement was likely in the near term. In the information technology area, the decision not to add Apple to the portfolio proved to be the greatest Pioneer Research Growth Fund | Annual Report | 8/31/08 5 detractor to the Fund's performance relative to the Russell 1000 Index. We believed Apple, which benefited from strong sales from a variety of its products, was overpriced relative to its underlying value, and we also had doubts about its longer-term growth prospects. Q What is your investment outlook? A We intend to keep the Fund defensively positioned, especially in the financials and consumer discretionary sectors, until we see clear evidence of market stability. We think lending activity by financials corporations will continue to be restricted until the real estate market begins to turn around. Until then, rising unemployment and declining housing values should maintain pressure on consumer activity. We intend to maintain our emphasis on bottom-up fundamental analysis of individual companies, as we look for corporations in all sectors of the market that we believe have the ability to perform, even in a period of uncertainty. Please refer to the Schedule of Investments on pages 14-17 for a full listing of Fund securities. Investing in small and mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The net expense ratio reflects contractual expense limitations currently in effect through 1/1/10 for Class Y Shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. Please see the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. The Russell 1000[RegTM] Growth Index measures the performance of large-cap U.S. growth stocks. Index returns assume reinvestment of dividends and, unlike Fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in any index. Pioneer Research Growth Fund | Annual Report | 8/31/08 11 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (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 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Research Value Fund Based on actual returns from March 1, 2008 through August 31, 2008. - -------------------------------------------------------------------------------- Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 3/1/08 - -------------------------------------------------------------------------------- Ending Account Value $ 967.00 $ 1,023.60 $ 1,021.50 (after expenses) on 8/31/08 - -------------------------------------------------------------------------------- Expenses Paid $ 6.18 $ 2.38 $ 0.80 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 1.83%, and 0.90% multiplied by the average account value over the period, multiplied by 184/366 for Class A, 47/366 for Class C, and 32/366 for Class Y (to reflect the partial year period). 12 Pioneer Research Growth Fund | Annual Report | 8/31/08 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. 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 Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Select Research Growth Fund, formerly Pioneer Select Research Growth Fund, (the Fund) is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund was organized on October 12, 2005, and commenced operations on December 15, 2005. The Fund's investment objective is long-term capital growth. The Fund offers three classes of shares - Class A, Class C and Class Y shares. Class C and Class Y shares were first publicly offered on July 17, 2008 and July 31, 2008, respectively. Each class of shares represents and interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that the level of transfer agent and distribution fees may differ among classes. Class A and Class C shareowners have exclusive voting rights with respect to the distribution plan for each class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectuses (unaudited) contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements which are consistent with those policies generally accepted in the investment company industry: 24 Pioneer Research Growth Fund | Annual Report | 8/31/08 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use the fair value of a security including a non-U.S. security when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. At August 31, 2008, there were no securities fair valued. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. All tax returns filed thus far are open (subject to examination by tax authorities). The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. Pioneer Research Growth Fund | Annual Report | 8/31/08 25 The Fund has elected to defer $16,877 of capital losses recognized between November 1, 2007 and August 31, 2008 to its fiscal year ending August 31, 2009. At August 31, 2008, the Fund has reclassified $3 to decrease accumulated net realized loss on investments and $3 to decrease undistributed net investment income to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax basis. The tax character of distributions paid during the years ended August 31, 2008 and August 31, 2007 were as follows. 2008 2007 Distributions paid from: Ordinary income $42,593 $1,640 Long term capital gain 16,052 -- - ------------------------------------------------ Total $58,645 $1,640 ================================================ The following shows the components of distributable earnings on a federal income tax basis at August 31, 2008: 2008 Distributable earnings: Undistributed ordinary income $ 1,615 Current year post October loss deferred (16,877) Unrealized appreciation 16,780 - ---------------------------------------------------- Total $ 1,518 ==================================================== C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned no underwriting commissions on the sale of Class A shares during the year ended August 31, 2008. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). 26 Pioneer Research Growth Fund | Annual Report | 8/31/08 Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, on the same day, and in the same amount, except that Class A, Class C, and Class Y shares bear different transfer agent and distribution expense rates. E. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a loan, the Fund receives collateral and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The loans are secured by collateral which is required to be at least 102%, at all times, of the fair value of the securities loaned. The amount of collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreement to recover the securities from the borrower on demand. The Fund invests cash collateral in cash equivalent investments. Securities lending collateral is managed by Credit Suisse, Inc. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.75% of the Fund's average daily net assets up to $1 billion and 0.70% on assets over $1 billion. For the year ended August 31, 2008, the net management fee was equivalent to 0.75% of the average daily net assets. Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.25%, 2.15% and 0.90% of the average daily net assets attributable to Class A, Class C and Class Y shares, respectively. These expense limitations are in effect through January 1, 2011 for Class A shares and through January 1, 2009 for Class C and January 1, 2010 for Class Y shares. In addition, under the management and administration agreements, certain other services, including accounting, regulatory reporting and insurance, are paid by the Fund. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,093 in management fees, administrative costs and certain other services payable from PIM at August 31, 2008. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in Pioneer Research Growth Fund | Annual Report | 8/31/08 27 "Due to affiliates" reflected on the Statement of Assets and Liabilities is $127 in transfer agent fees payable to PIMSS at August 31, 2008. 4. Distribution Plan The Fund adopted a Plan of Distribution for Class A and Class C shares (Class A Plan, and Class C Plan) in accordance with Rule 12b-1 under the Investment Company Act of 1940. Effective February 1, 2008, under the Class A Plan, the Fund pays PFD a service fee equal to 0.25% of the average daily net assets attributable to Class A shares to finance activities primarily intended to result in the sale of Class A shares. Prior to February 1, 2008, PFD was reimbursed for service fees in an amount up to 0.25% of the average daily net assets attributable to Class A shares. Pursuant to the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $32 in distribution fees payable to PFD at August 31, 2008. In addition, redemptions of Class A and Class C shares may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. There is no CDSC for Class Y Shares. Proceeds from the CDSCs are paid to PFD. For the year ended August 31, 2008, no CDSCs were paid to PFD. 5. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. 28 Pioneer Research Growth Fund | Annual Report | 8/31/08 Report of Independent Registered Public Accounting Firm To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Research Growth Fund: - -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Research Growth Fund (the Fund, formerly Pioneer Select Research Growth Fund) (one of the portfolios constituting Pioneer Series Trust V), including the schedule of investments, as of August 31, 2008, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits 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 and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2008, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Research Growth Fund at August 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts October 20, 2008 Pioneer Research Growth Fund | Annual Report | 8/31/08 29 ADDITIONAL INFORMATION (unaudited) For the year ended August 31, 2008, certain dividends paid by the Fund may be subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax Relief Reconciliation Act (the Act) of 2003.

Pioneer Research Growth Fund | Annual Report | 8/31/08 31 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine annually whether to continue the investment advisory agreement for the Fund. In connection with their most recent consideration of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 13, 2007, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the continuation of the investment advisory agreement for another year. At a meeting held on January 8, 2008, the Trustees considered whether an amended and restated investment advisory agreement for the Fund should be approved for an initial period ending December 31, 2009. The management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement is the same as the management fee provided in the previously approved investment advisory agreement. Based on their evaluation of the information provided by PIM, including the information provided by PIM in connection with the Trustees' most recent approval of the continuation of the previous investment advisory agreement, the Trustees, including the independent Trustees voting separately, unanimously approved the amended and restated investment advisory agreement. Shareholders of the Fund approved the amended and restated investment advisory agreement at a meeting held on May 13, 2008. In considering the amended and restated investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the amended and restated investment advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that were provided by PIM to the Fund under the previous investment advisory agreement, and that would continue to be provided by PIM to the Fund under the amended and restated investment advisory agreement, taking into account the investment objective and strategy of the Fund and the information related to 32 Pioneer Research Growth Fund | Annual Report | 8/31/08 the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the amended and restated investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provided under the previous investment advisory agreement and that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement, were satisfactory and consistent with the terms of the amended and restated investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees noted that the Fund commenced operations on December 15, 2005. They considered that the Fund's annualized total return was in the first quintile of its Morningstar category for the one year period ended June 30, 2007 and that the Fund's total return for 2006 was in the first quintile of its Morningstar category. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered that the management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement would be the same as the management fee to be paid by the Fund under the previously approved investment advisory agreement. The Trustees considered information on the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense Pioneer Research Growth Fund | Annual Report | 8/31/08 33 ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2007 was in the third quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2007 was in the first quintile relative to its Strategic Insight peer group. It was noted that PIM did not currently manage any accounts with an investment objective and strategies that were similar to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the size of the Fund, the quality of services provided by PIM, the investment performance of the Fund and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that PIM should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. The Trustees concluded that, because of the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. 34 Pioneer Research Growth Fund | Annual Report | 8/31/08 Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds and the benefits to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees further considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the terms of the amended and restated investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the amended and restated investment advisory agreement for the Fund.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920's. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme business slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares have been unjustifiably beaten down by indiscriminate selling, but that nonetheless have strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process is supported by an integrated team approach and results in the careful balance of risk and reward that we apply to each of our portfolios. While we see potential chances for making money in many corners of the market, it takes 2 Pioneer Research Value Fund | Annual Report | 8/31/08 research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Research Value Fund | Annual Report | 8/31/08 3 Portfolio Management Discussion | 8/31/08 Driven by growing fears about the effects of a global credit crisis that began with problems over U.S. subprime mortgages, prices of most domestic stocks fell over the 12 months ended August 31, 2008. In a highly volatile market, energy stocks showed the greatest positive performance, while financials stocks tended to suffer the greatest price losses. In the following discussion, members of the team responsible for managing Pioneer Research Value Fund review the 12-month period ended August 31, 2008. Diego Franzin, Ashesh Savla and John Peckham, CFA, discuss the factors that affected the Fund's performance over the period. Mr. Franzin is Head of Pioneer's U.S. Quantitative Research & Management; Mr. Savla is a Quantitative Analyst at Pioneer; and Mr. Peckham is Head of Pioneer's U.S. Equity Research Group. Q How did Pioneer Research Value Fund perform during the 12 months ended August 31, 2008? A Research Value Fund's Class A shares returned -13.34% at net asset value over the period, while the Fund's benchmark, the Russell 1000 Value Index (the Russell Index), returned -14.66% during the same period. Over the same 12 months, the average return of the 845 funds in Lipper's Large-Cap Core Funds category was -10.64% Q What were the principal factors affecting the Fund's performance during the 12 months ended August 31, 2008? A The deepening global credit crisis arising from problems in the domestic subprime mortgage area created significant uncertainty in the minds of investors, contributing to extreme volatility in the markets. The two most volatile sectors in the market were the financials group, where stock prices fell for the many companies directly exposed to credit problems, and the energy group, where prices of many companies rose because of the effects of rapidly rising oil and natural gas prices. The changes in stock prices in those two sectors contributed most of the volatility to the market. It was an unusual period in which technical factors, such as the flow of funds, had a greater influence on the markets than did fundamental issues, such as the underlying quality and profitability of individual companies. Investors often based their decisions on their expectations of policy changes by the U.S. Federal Reserve Board (the Fed), the nation's central bank. The Fed was pulled in two different directions as it considered adjustments in monetary policy -- the need to cut interest rates to add financial liquidity to the financial markets -- against the need to raise interest rates to stave off the inflationary effects of rising energy and commodity prices. While the overall market sentiment was bearish, with stock prices falling, the period also was 4 Pioneer Research Value Fund | Annual Report | 8/31/08 unusual in that growth stocks tended to outperform value stocks. Typically, growth stocks tend to outperform in bull markets, when stock prices are rising, while value stocks have often outperformed in bear markets. Consistent with the investment style of the Fund, stock selection had the greatest influence on performance relative to the benchmark Russell Index. We kept the Fund's sector weightings consistent with the positioning of the Russell Index. The approximately 50 stocks in the portfolio included both growth and value companies, and were selected using both qualitative research techniques and quantitative analysis tools. We began by ranking the 100 stocks, according to Pioneer's research analysts, with a quantitative screening process that we developed based upon our research into the performance of stocks in 17 different sectors and industries. We then made final selections based on the fundamental analysis research of Pioneer's Equity Research Group. In a volatile market, we focused on higher-quality companies that had strong balance sheets and relatively low debt, and so the Fund was not greatly exposed to the problems in the credit markets. Q What types of investments most influenced the Fund's results over the 12 months ended August 31, 2008? A The Fund's positions in the industrials, utilities and energy sectors had the greatest positive effects on results. Within the industrials group, the Fund's holding in SPX, a specialist in major energy-related infrastructure projects, substantially helped performance. SPX benefited from investments in power infrastructure globally, including in emerging markets. The decision not to add General Electric (GE) to the portfolio also helped the Fund's relative performance. We avoided GE primarily because of the diversified corporation's exposure to the credit markets. Among the Fund's utilities holdings, an investment in Questar provided a significant performance boost. A gas utility, Questar also has significant natural gas exploration and production operations, which were helped by increasing natural gas prices. In energy, Apache and Weatherford International were particularly strong performers, as both benefited from the significant increases in oil and natural gas prices. Apache is a global oil and gas exploration and production company. Weatherford International, an oil field services corporation, prospered as it continued to expand internationally. Investments in the health care and financials sectors proved to be the greatest drag on the Fund's performance. In health care, the most notable disappointments were Merck and Schering-Plough, two large pharmaceutical companies. Their stock valuations fell after questions arose about the effectiveness of Zetia and Vytorin, anti-cholesterol drugs in which both companies had an interest. In the financials sector, the greatest detractors were the Fund's investments in First Marblehead and Freddie Mac. First Pioneer Research Value Fund | Annual Report | 8/31/08 5 Marblehead, which specializes in securitizing student loans, was hurt when the market for securitized loans dried up in the credit crisis. Freddie Mac, the giant government-sponsored mortgage institution, fell victim to the effects of the subprime mortgage crisis. We liquidated the Fund's investments in both companies before the end of the fiscal year (August 31). However, we maintained the Fund's investment in another financials corporation that hurt results: Zions Bancorporation, a bank holding company based in Utah with significant mortgage exposure in California, Nevada and Arizona, which was hurt by the downturn in real estate activity in those states. We maintained the Fund's position because we think Zions is a well managed company with good potential to gain market share over the longer term. Q What is your investment outlook? A We intend to keep the Fund defensively positioned, especially in the financials and consumer discretionary sectors, until we see clear evidence of market stability. We think lending activity by financials corporations will continue to be restricted until the real estate market begins to turn around. Until then, rising unemployment and declining housing values should maintain pressure on consumer activity. We intend to maintain our emphasis on bottom-up fundamental analysis of individual companies, as we look for corporations in all sectors of the market that we believe have the ability to perform, even in a period of uncertainty. Please refer to the Schedule of Investments on pages 14-19 for a full listing of Fund securities. Investing in small and mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

Pioneer Research Value Fund | Annual Report | 8/31/08 11 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (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 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Research Value Fund Based on actual returns from March 1, 2008 through August 31, 2008. - -------------------------------------------------------------------------------- Actual Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 3/01/08 - -------------------------------------------------------------------------------- Ending Account Value $ 951.37 $ 1,023.40 $ 1,015.80 (after expenses) on 8/31/08 - -------------------------------------------------------------------------------- Expenses Paid $ 6.13 $ 2.73 $ 0.79 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%, and 0.90% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 for Class A, 46/366 for Class C and 32/366 for Class Y (to reflect the partial year period). 12 Pioneer Research Value Fund | Annual Report | 8/31/08 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. 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 Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Research Value Fund, formerly Select Research Value Fund, (the Fund) is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund was organized on October 12, 2005, and commenced operations on December 15, 2005. Pioneer Investment Management Inc. (PIM), the Fund's investment advisor, paid all organizational costs of the Fund. Prior to December 15, 2005, the Fund had no operations other than those relating to organizational matters and the initial capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD) the principal underwriter for the Fund. The Fund's investment objective is to seek long-term capital growth. The Fund offers three classes of shares -- Class A, Class C, and Class Y shares. Class C shares were first publicly offered on July 17, 2008. Class Y shares were first publicly offered on July 31, 2008. Each class of shares represent an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that each class of shares can bear different transfer agent and distribution fees and have exclusive voting right with respect to the distribution plans that have been adopted by Class A and Class C shareowners, respectively. There is no distribution plan for Class Y shares. Investing in small and mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund's prospectuses (unaudited) contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements which are consistent with those policies generally accepted in the investment company industry: 26 Pioneer Research Value Fund | Annual Report | 8/31/08 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use the fair value of a security including a non-U.S. security when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. As of August 31, 2008, there were no securities fair valued. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. All tax returns filed thus far are open (subject to examination by tax authorities). The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, as from paid-in capital, depending on the type of book/tax differences that may exist. Pioneer Research Value Fund | Annual Report | 8/31/08 27 The Fund has elected to defer $21,729 of capital losses recognized between November 1, 2007 and August 31, 2008 to its fiscal year ending August 31, 2009. At August 31, 2008, the Fund has reclassified $169 to decrease undistributed net investment income and $169 to accumulated net realized loss on investments, to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax basis. The tax character of distributions paid during the years ended August 31, 2008 and August 31, 2007 were as follows: -------------------------------------------------------------------- 2008 2007 -------------------------------------------------------------------- Distributions paid from: Ordinary income $22,689 $20,265 Long-term capital gain 21,742 -- -------------------------------------------------------------------- Total $44,431 $20,265 ==================================================================== The following shows the components of distributable earnings on a federal income tax basis at August 31, 2008: -------------------------------------------------------------------- 2008 -------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 4,697 Current year post October loss deferred (21,729) Unrealized appreciation 809 -------------------------------------------------------------------- Total $ (16,223) ==================================================================== The difference between book basis and tax basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned subsidiary of UniCredit S.p.A. (UniCredit), earned no underwriting commissions on the sale of Class A shares during the year ended August 31, 2008. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. 28 Pioneer Research Value Fund | Annual Report | 8/31/08 Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class share all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, and in the same amount, except that Class A, Class C and Class Y shares can bear different transfer agent and distribution fees. E. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a loan, the Fund receives collateral and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The loans are secured by collateral which is required to be at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in cash equivalent investments. Securities lending collateral is managed by Credit Suisse, Inc. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.75% of the Fund's average daily net assets up to $1 billion and 0.70% of the excess over $1 billion. For the year ended August 31, 2008, the management fee was equal to 0.75% of the Fund's average daily net assets. PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit the Fund's expenses to 1.25%, 2.15%, and 0.90% of the average daily net assets attributable to Class A, Class C, and Class Y shares, respectively. These limitations are in effect through January 1, 2011 for Class A shares and through January 1, 2009 for Class C and Class Y shares. Pioneer Research Value Fund | Annual Report | 8/31/08 29 In addition, under the management and administration agreements, certain other services, including accounting, regulatory reporting and insurance, are paid by the Fund. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $65 in management fees, administrative costs and certain other services payable to PIM at August 31, 2008. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $180 in transfer agent fees payable to PIMSS at August 31, 2008. 4. Distribution Plan The Fund adopted a Plan of Distribution with respect to Class A and Class C shares in accordance with Rule 12b-1 of the Investment Company Act of 1940. Effective February 1, 2008, under the Class A Plan, the Fund pays PFD a service fee equal to 0.25% of the average daily net assets attributable to Class A shares to finance activities primarily intended to result in the sale of Class A shares. Prior to February 1, 2008, PFD was reimbursed for service fees in an amount up to 0.25% of the average daily net assets attributable to Class A shares. Pursuant to the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Included in due to affiliates is $32 in distribution fees payable to PFD at August 31, 2008. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. There is no CDSC's for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended August 31, 2008 there were no CDSCs were paid to PFD. 5. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. 30 Pioneer Research Value Fund | Annual Report | 8/31/08 In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. Pioneer Research Value Fund | Annual Report | 8/31/08 31 Report of Independent Registered Public Accounting Firm To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Research Value Fund: - -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Research Value Fund (the Fund, formerly Pioneer Select Research Value Fund) (one of the portfolios constituting Pioneer Series Trust V), including the schedule of investments, as of August 31, 2008, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits 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 and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2008, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Research Value Fund at August 31, 2008, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts October 20, 2008 32 Pioneer Research Value Fund | Annual Report | 8/31/08 ADDITIONAL INFORMATION (unaudited) For the year ended August 31, 2008, certain dividends paid by the Fund may be subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax Relief Reconciliation Act (the Act) of 2003.

(PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine annually whether to continue the investment advisory agreement for the Fund. In connection with their most recent consideration of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 13, 2007, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the continuation of the investment advisory agreement for another year. At a meeting held on January 8, 2008, the Trustees considered whether an amended and restated investment advisory agreement for the Fund should be approved for an initial period ending December 31, 2009. The management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement is the same as the management fee provided in the previously approved investment advisory agreement. Based on their evaluation of the information provided by PIM, including the information provided by PIM in connection with the Trustees' most recent approval of the continuation of the previous investment advisory agreement, the Trustees, including the independent Trustees voting separately, unanimously approved the amended and restated investment advisory agreement. Shareholders of the Fund approved the amended and restated investment advisory agreement at a meeting held on May 13, 2008. In considering the amended and restated investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the amended and restated investment advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that were provided by PIM to the Fund under the previous investment advisory agreement, and that would continue to be provided by PIM to the Fund under the amended and restated investment advisory agreement, taking into account the investment objective and strategy of the Fund and the information related to Pioneer Research Value Fund | Annual Report | 8/31/08 35 the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the amended and restated investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provided under the previous investment advisory agreement and that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement, were satisfactory and consistent with the terms of the amended and restated investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees noted that the Fund commenced operations on December 15, 2005. They considered that the Fund's annualized total return was in the third quintile of its Morningstar category for the one year period ended June 30, 2007 and that the Fund's total return for 2006 was in the second quintile of its Morningstar category. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered that the management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement would be the same as the management fee to be paid by the Fund under the previously approved investment advisory agreement. The Trustees considered information on the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense 36 Pioneer Research Value Fund | Annual Report | 8/31/08 ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2007 was in the third quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2007 was in the second quintile relative to its Strategic Insight peer group. It was noted that PIM did not currently manage any accounts with an investment objective and strategies that were similar to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the size of the Fund, the quality of services provided by PIM, the investment performance of the Fund and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that PIM should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. The Trustees concluded that, because of the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. Pioneer Research Value Fund | Annual Report | 8/31/08 37 Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds and the benefits to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees further considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the terms of the amended and restated investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the amended and restated investment advisory agreement for the Fund. 38 Pioneer Research Value Fund | Annual Report | 8/31/08 Trustees, Officers and Service Providers Investment Adviser Pioneer Investment Management, Inc.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.

Beginning with non-audit service contracts entered into on or after May 6, 2003, the effective date of the new SEC pre-approval rules, the Fund's audit committee is required to pre-approve services to affiliates defined by SEC rules to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Fund. For the years ended August 31, 2008 and 2007, there were no services provided to an affiliate that required the Fund's audit committee pre- approval.

The aggregate non-audit fees for the Fund and affiliates, as previously defined, totaled approximately $41,446 in 2008 and $39,100 in 2007. (h) Disclose whether the registrant's audit committee of the board of trustees has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any subadviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence. The Fund's audit committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the Affiliates (as defined) that were not pre- approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
