They were particularly useful guides during the past year, when an otherwise healthy long-term bull market was buffeted by problems in the mortgage and banking industries. Since mid-year, issues tied to poor underwriting practices in the subprime sector of the mortgage industry, and to problems with risk management by banks and hedge funds, have resulted in increased market volatility and rising concern about risks to U.S. economic growth. Even against this backdrop, the long-term performance of major asset classes remained positive. In the 12 months ending August 31, 2007, equity investors were generally rewarded as, despite a late-July decline, the Standard & Poor's 500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the NASDAQ Composite Index returned 19%. International developed and emerging markets equities performed well also, with the MSCI EAFE Developed Market Index returning 19% and the MSCI Emerging Markets Index returning 44% over the 12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 7% for the same period, reflecting its higher coupon yield. U.S. economic growth has slowed in the past year, but this was due as much to the natural maturation of the cyclical expansion, as U.S. factories approached full utilization and the labor market approached full employment, as it was to rising commodity prices and short-term interest rates. This slowdown was, therefore, not entirely unwelcome, as it reduced the threat of higher inflation. More recently, however, there has been increasing concern that falling home prices and/or banks' unwillingness to lend pose a larger and more imminent threat to the economy. In Europe, solid GDP growth driven by a positive operating environment for European companies, especially exporters, has driven unemployment lower and supported growing consumption. Japanese economic growth also continues to make progress, and the country's deflationary problems are gradually receding. Economic growth in emerging market countries remains faster than in the developed world as they persist in "catching up," led by China, which continues its rise as a world economic power. 2 Letter The U.S. Federal Reserve and the world's other central banks have pursued policies aimed at producing low and stable inflation, believed to be the best backdrop for steady economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so central bank policies have also been "investor friendly." The central banks have responded to this past summer's liquidity squeeze in the inter-bank and commercial paper markets by acting as the "lenders of last resort" to limit the risk of problems spreading to the broader economy. Looking forward, the economic outlook and equity valuations appear generally positive, although the current environment is plagued by fears that subprime mortgage problems will result in a systemic liquidity/credit crunch. While falling risk tolerances may depress asset prices in the short term, valuations look reasonable if credit market problems do not spread to the broader economy. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to your particular risk tolerance and investment objective.

Q: How did the Fund perform over the 12-month period ended August 31, 2007? A: The Fund's total return from September 1, 2006 through August 31, 2007 was 14.58% (Class A shares at net asset value) versus 17.54% for the MSCI World Index. The global environment for equities was generally positive for the 12-month period, and this was reflected in the Fund's performance. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. 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 somewhat concentrated portfolio of less 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," so there is a strong value component to our analysis. We try to find 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 try to 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. 4 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q: Could you characterize the global equity markets over the period? A: Global equity markets in the aggregate enjoyed strong positive returns over the period, despite periods of significant volatility. Markets declined sharply during the final week of February 2007. The drop began with a sharp decline in Chinese equities, based on rumors that the government would seek to tighten stock market investment rules and introduce a capital gains tax. The release of some weaker-than-expected U.S. economic data and evidence of mounting problems in the subprime U.S. mortgage market further added to a sense of unease among investors. As equity markets weakened, the Japanese yen rose strongly against the U.S. Dollar, which suggested that the broad-based decline in equities was partially due to the unwinding of so called "carry trades" funded through borrowing at low Japanese interest rates. As the second half of the fiscal period progressed, merger-and-acquisition activity helped restore a better tone to the equity markets, with most sectors experiencing some activity. In particular, there were significant deals announced in the banking, utilities and materials sectors. On the economic front, conditions in the United States remained consistent with growth that had been below trend, while European economic activity remained generally solid. In June 2007, global markets weakened, as stronger inflation and housing market data in the United States pushed interest rate expectations and bond yields higher. In addition, problems related to subprime mortgage exposure emerged at the hedge fund units of Bear Stearns and UBS, which added to risk aversion among investors. In July and August 2007, the full extent of the sub-prime issue began to come to light. It became clear that, due to rising defaults, the leading subprime lenders would not be able to meet their obligations to the Wall Street firms that repackage these loans and sell them to investors globally. The resulting credit crunch and heightened awareness of the global distribution of risk caused markets to drop sharply. As August progressed, equities began to make up some of the lost ground. European equities outperformed both U.S. and Japanese equities in the 12 months ended August 31, 2007, helped in part by the strength of the euro relative to the U.S. Dollar. From a sector 5 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 8/31/07 (continued) - -------------------------------------------------------------------------------- perspective, the strongest areas in the global equity markets were materials, industrials and energy stocks, while the weakest returns were in the financials and consumer discretionary sectors. Q: What strategies or holdings helped and hurt performance over the fiscal period? A: Our sector allocation proved unrewarding on the whole, but stock selection was a larger factor in the Fund's somewhat lagging performance relative to the benchmark during the fiscal period. Our holdings in the financial sector, particularly among insurance companies, were among the leading detractors from the Fund's relative performance. We emphasized insurers during the fiscal year, and the leading underperformers among those holdings were AIG and MBIA, both of whom suffered from concerns over the impact of the subprime crisis on their bond insurance businesses. Among diversified financials, our holdings in Citigroup and Merrill Lynch were also penalized by market concerns over subprime loans, as well as over future bond issuance and trading volumes. In healthcare, we were modestly underweight on average for the fiscal period but overweight in pharmaceuticals companies. The pharmaceutical segment was weaker than the wider market, and this negative effect was compounded by the underperformance of our holdings, led by UK firm AstraZeneca. AstraZeneca's stock faltered in late 2006 after the company cancelled further development of a new stroke drug and lost patent protection on an ulcer drug in Europe. Bristol-Myers Squibb was the only positive contributor among pharmaceuticals in the fiscal period, as the patent on its leading blood-thinning drug Plavix was upheld by a U.S. court. Stock selection was also weak in the consumer discretionary sector during the fiscal period, where holdings in consumer durables such as Japanese companies Sekisui Chemical and Daito Trust Construction, fell strongly. Among retailers, Office Depot also acted as a drag on returns. The Fund benefited from positive stock selection in the telecommunications sector during the fiscal period, led by positions in Vodafone and Verizon. Vodafone rose sharply in the fiscal period, thanks to its better-than-expected profits guidance, which 6 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- accompanied its full-year results in May. In the automobile sector, our holdings of Porsche advanced very strongly over the year, easily offsetting the negative relative returns from our position in Toyota. We deemphasized materials overall during the fiscal period, but our stock selection within the sector proved very successful. BASF, a German chemicals company, was the most successful stock pick in this area. Its second quarter results beat expectations, helped by higher prices and the contributions of acquisitions. The company is also in the midst of a large share buyback program. Mining company Rio Tinto also rose sharply amid merger rumors and continuing buoyant demand for metals from emerging markets. Q: What is your outlook and how is it reflected in the Fund? A: Looking ahead, global economic and company fundamentals remain supportive for equities. In general, global economic growth outside of the United States appears to be maintaining solid forward momentum, most notably in Europe and Asia. In the United States, the adjustment in housing and problems in the subprime mortgage sector are likely to remain headwinds for the economy, suggesting below-trend growth may persist. While equity valuations versus fixed-income are no longer as compelling following the recent increase in bond yields, particularly in the United States, current levels continue to justify an overall preference for equities in our view. 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. 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 7 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 8/31/07 (continued) - -------------------------------------------------------------------------------- common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

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, 2007 through August 31, 2007 Share Class A B C - ---------------------------------------------------------------------------- Beginning Account Value On 3/1/07 $1,000.00 $1,000.00 $1,000.00 Ending Account Value (after expenses) $1,049.36 $1,043.85 $1,045.54 On 8/31/07 Expenses Paid During Period* $ 6.72 $ 11.33 $ 11.34 * 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 184/365 (to reflect the one half year period). 14 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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.

Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 - -------------------------------------------------------------------------------- 1. 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. Prior to October 12, 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 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. 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. Information regarding the Fund's principal risk is contained in the Fund's prospectus(es). Please refer to those documents when considering the Fund's 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 periods. 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 29 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- 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 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. 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 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. 30 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. 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 either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. At August 31, 2007, the Fund reclassified $44 to decrease undistributed net investment income and $44 to increase accumulated net realized gain on investments 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. There were no distributions paid by the Fund during the period ended August 31, 2006. The tax character of distributions paid during the year ended August 31, 2007 was as follows: - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $53,086 ------- Total $53,086 ======= - -------------------------------------------------------------------------------- 31 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at August 31, 2007. - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Undistributed ordinary income $ 85,596 Undistributed long-term gain 153,135 Unrealized appreciation 163,019 -------- Total $401,750 ======== - -------------------------------------------------------------------------------- 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 UniCredito Italiano S.p.A., (UniCredito Italiano), earned $1,997 in underwriting commissions on the sale of Class A shares during the year ended August 31, 2007. 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 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 32 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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, 2007, the Fund had no outstanding portfolio hedges. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredito Italiano, 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, 2007, the net management fee was equivalent to 0.75% of the 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 1.30%, 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, 2009 for Class A and through January 1, 2008 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. At August 31, 2007, $89 was payable to PIM related to management fees, administrative costs and certain other services and is included in due to affiliates. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates is $1,984 in transfer agent fees payable to PIMSS at August 31, 2007. 33 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- 4. Distribution Plans and Service Plans The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the Investment Company Act of 1940. The Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of Class A shares. Pursuant to the Class B Plan and 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 B and Class C shares. Included in due to affiliates is $71 in distribution fees payable to PFD at August 31, 2007 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%. Proceeds from the CDSCs are paid to PFD. For the year ended August 31, 2007, CDSCs in the amount of $237 were paid to PFD. 5. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of no later than February 29, 2008. At this time, management is evaluating the implications of 34 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- FIN 48 and any impact in the financial statements has not yet been determined. 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. 35 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- 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, including the schedule of investments, of Pioneer Global Select Equity Fund (the Fund) (one of the portfolios constituting Pioneer Series Trust V) as of August 31, 2007, 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, 2007, 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 Global Select Equity Fund at August 31, 2007, 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 12, 2007 36 Pioneer Global Select Equity Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.

They were particularly useful guides during the past year, when an otherwise healthy long-term bull market was buffeted by problems in the mortgage and banking industries. Since mid-year, issues tied to poor underwriting practices in the subprime sector of the mortgage industry, and to problems with risk management by banks and hedge funds, have resulted in increased market volatility and rising concern about risks to U.S. economic growth. Even against this backdrop, the long-term performance of major asset classes remained positive. In the 12 months ending August 31, 2007, equity investors were generally rewarded as, despite a late-July decline, the Standard & Poor's 500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the NASDAQ Composite Index returned 19%. International developed and emerging markets equities performed well also, with the MSCI EAFE Developed Market Index returning 19% and the MSCI Emerging Markets Index returning 44% over the 12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 7% for the same period, reflecting its higher coupon yield. U.S. economic growth has slowed in the past year, but this was due as much to the natural maturation of the cyclical expansion, as U.S. factories approached full utilization and the labor market approached full employment, as it was to rising commodity prices and short-term interest rates. This slowdown was, therefore, not entirely unwelcome, as it reduced the threat of higher inflation. More recently, however, there has been increasing concern that falling home prices and/or banks' unwillingness to lend pose a larger and more imminent threat to the economy. In Europe, solid GDP growth driven by a positive operating environment for European companies, especially exporters, has driven unemployment lower and supported growing consumption. Japanese economic growth also continues to make progress, and the country's deflationary problems are gradually receding. Economic growth in emerging market countries remains faster than in the developed world as they persist in "catching up," led by China, which continues its rise as a world economic power. 2 Letter The U.S. Federal Reserve and the world's other central banks have pursued policies aimed at producing low and stable inflation, believed to be the best backdrop for steady economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so central bank policies have also been "investor friendly." The central banks have responded to this past summer's liquidity squeeze in the inter-bank and commercial paper markets by acting as the "lenders of last resort" to limit the risk of problems spreading to the broader economy. Looking forward, the economic outlook and equity valuations appear generally positive, although the current environment is plagued by fears that subprime mortgage problems will result in a systemic liquidity/credit crunch. While falling risk tolerances may depress asset prices in the short term, valuations look reasonable if credit market problems do not spread to the broader economy. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to your particular risk tolerance and investment objective.

In the following interview, portfolio manager Timothy Pynchon discusses the factors that affected the municipal bond market and the Fund over the semiannual period. Q: How did the Fund perform during the period ending August 31, 2007? A: For the six-month period ended August 31, 2007, Pioneer High Income Municipal Fund's Class A shares produced a total return of -2.49% at net asset value. The Fund's benchmark, the Lehman Brothers High Yield Municipal Bond Index, returned -1.89% for the same period, and the average return of the 95 funds in the Lipper High Yield Municipal Debt Funds category was -3.31% for the six-month period ended August 31, 2007. Lipper is an independent monitor of mutual fund performance. The Fund's Class A shares generated a 30-day SEC tax-free yield of 5.54%, based on the maximum income tax rate of 35%. At the end of the period, the Fund had 38 issues in 21 states, and the average credit quality of the portfolio was BB. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What was the investment backdrop like during the six months? A: The period can be divided into two distinct parts. For the first five months, high-yield municipal securities posted solid gains against a backdrop of relatively strong economic growth and relatively low interest rates. Investor demand was robust, as new types of investors, such as hedge funds, sought the higher tax-advantaged yields that below-investment-grade municipal bonds can provide. In August it became apparent that the subprime mortgage problem that had overshadowed the financial markets for several months was worse than originally thought. (Subprime mortgages are loans to less 4 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- creditworthy buyers.) As some home owners defaulted on their mortgages, the lower-quality securities that were backed by those mortgages sold off, and investors lost confidence in the riskiest assets, which had been market leaders for more than a year. The volatility from subprime mortgage issues affected most of the fixed-income markets. Bond yields rose dramatically, and prices declined in a way that we had not seen in several years. In some cases bond yields rose 80 to 120 basis points. (A basis point equals 0.01%.) The fixed-income market was in disarray for about three weeks, before it began to firm up and become more orderly. At the end of the period, the high-yield municipal bond market had been re-priced to levels that appeared appropriate for risky and non-rated assets. Q: How did you manage the Fund in this environment? A: We had no exposure to subprime mortgages during the period; however, the subprime mortgage problem affected virtually all fixed-income assets. While some of our positions lost value, we viewed the market volatility as an opportunity and positioned the Fund to deliver what we believe will be a strong total return in the future. As yields rose and prices declined, we sought to add yield and raise the credit quality of the portfolio. We traded some of the portfolio's non-rated credits for BBB-rated tobacco bonds, which we purchased at deep discounts and which we believe should benefit from capital appreciation. (Tobacco bonds 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.) We kept the portfolio diversified among a variety of economic sectors. Some of the best yields were in the health care area, which was the biggest position in the portfolio. Health care is a large and growing part of the economy and encompasses several areas, such as hospitals, nursing homes and continuing care retirement communities, among others. The education, housing, transportation and water and sewer sectors were also represented in the portfolio. In selecting securities, we favored revenue bonds whose interest and principal are paid from the revenues derived from the particular asset the bond was issued to finance. Because longer-term yields were higher than shorter-term yields, we emphasized 5 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 8/31/07 (continued) - -------------------------------------------------------------------------------- bonds with relatively long maturities. About 27% of the portfolio's securities had maturities in the six to ten-year range, and about 57% had maturities of more than 10 years at the end of the fiscal period. Q: What influenced the Fund's performance? A: The impact of the subprime mortgage problem on the municipal bond market was unusual and broad. As investors grew concerned about a credit crunch, they traded out of lower quality high-yielding assets into high quality assets, such as Treasury securities. Because investors sought quality above everything else, demand for high-yielding municipal bonds, like the ones held by the portfolio, declined, and their prices went down. Even though the yields on the securities rose, the price erosion had a negative effect on the Fund's total return. Q: What is your outlook for the next six months? A: We are positive in our assessment for the high-yield municipal bond market over the next several months. As investors seek higher tax-advantaged yields, we expect demand for high-yield, lower-rated bonds to rise. During the recent market volatility, we restructured the portfolio, which we believe is poised to deliver a relatively high total return over the next several months. 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. 6 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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.

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, 2007 through August 31, 2007. Share Class A C Y - ------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 On 3/1/07 Ending Account Value $ 975.01 $ 970.66 $ 971.84 On 8/31/07 Expenses Paid $ 4.48 $ 8.94 $ 6.11 During Period* * Expenses are equal to the Fund's annualized expense ratio of 0.90%, 1.80% and 1.23% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the half year period). 13 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- 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.

Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 - -------------------------------------------------------------------------------- 1. 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 have 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 plans that have 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. More detailed descriptions of the Fund's principal risks are contained in the Fund's prospectuses. Please refer to those documents when considering the Fund's 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: 27 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- 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 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, 2007 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 either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The Fund has elected to defer approximately $626,029 of capital losses recognized between November 1, 2006 and August 31, 2007 to its fiscal year ending August 31, 2008. 28 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The Fund has reclassified $3,254 to decrease paid-in capital, $296 to increase accumulated net realized loss on investments and $3,550 to increase undistributed net investment income 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 tax character of distributions paid during the year ended August 31, 2007 was as follows: - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Distributions paid from: Tax-exempt income $433,538 Ordinary income 38 -------- Total $433,576 ======== - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at August 31, 2007. - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Undistributed tax-exempt income $ 131,679 Current year dividend payable (83,862) Current year post-october loss deferral (626,029) Unrealized depreciation (383,340) --------- Total $(961,552) ========= - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax basis adjustments on partnerships and the tax treatment of premium and amortization. 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 UniCredito Italiano S.p.A., (UniCredito Italiano), earned $11,099 in underwriting commissions on the sale of Class A shares during the period ended August 31, 2007. 29 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- D. Class Allocations 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). 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. 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 fees. 2. Management Agreement Pioneer Investment Management, Inc., (PIM), a wholly owned indirect subsidiary of UniCredito Italiano, 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, 2007, the net management fee was equivalent to 0.50% of average daily 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, 2009 and the Class C limitation is in effect through January 1, 2008. 30 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. At August 31, 2007, $342 was payable to PIM related to management fees, administrative costs and certain other services and is included in due to affiliates. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareholder services to the Fund at negotiated rates. Included in due to affiliates is $0 in transfer agent fees payable from PIMSS at August 31, 2007. 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. Pursuant to the Class A Plan, the Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of 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 is $216 in distribution fees payable to PFD at August 31, 2007. 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 period ended August 31, 2007, no CDSCs were paid to PFD. 31 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- 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 period ended August 31, 2007, the Fund's expenses were not reduced under such arrangements. 6. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of no later than February 29, 2008. At this time, management is evaluating the implications of FIN 48 and any impact in the financial statements has not yet been determined. 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. 32 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer High Income Municipal Fund: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer High Income Municipal Fund (the Fund) (one of the portfolios constituting Pioneer Series Trust V) as of August 31, 2007, and the related statement of operations, the statement of changes in net assets, and the financial highlights for the period from October 17, 2006 (Commencement of Operations) to August 31, 2007. 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 audit. We conducted our audit 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 audit 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, 2007, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audit provides 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 High Income Municipal Fund at August 31, 2007, the results of its operations, the changes in its net assets, and the financial highlights for the period from October 17, 2006 (Commencement of Operations) to August 31, 2007, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts October 12, 2007 33 Pioneer High Income Municipal Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.

They were particularly useful guides during the past year, when an otherwise healthy long-term bull market was buffeted by problems in the mortgage and banking industries. Since mid-year, issues tied to poor underwriting practices in the subprime sector of the mortgage industry, and to problems with risk management by banks and hedge funds, have resulted in increased market volatility and rising concern about risks to U.S. economic growth. Even against this backdrop, the long-term performance of major asset classes remained positive. In the 12 months ending August 31, 2007, equity investors were generally rewarded as, despite a late-July decline, the Standard & Poor's 500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the NASDAQ Composite Index returned 19%. International developed and emerging markets equities performed well also, with the MSCI EAFE Developed Market Index returning 19% and the MSCI Emerging Markets Index returning 44% over the 12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 7% for the same period, reflecting its higher coupon yield. U.S. economic growth has slowed in the past year, but this was due as much to the natural maturation of the cyclical expansion, as U.S. factories approached full utilization and the labor market approached full employment, as it was to rising commodity prices and short-term interest rates. This slowdown was, therefore, not entirely unwelcome, as it reduced the threat of higher inflation. More recently, however, there has been increasing concern that falling home prices and/or banks' unwillingness to lend pose a larger and more imminent threat to the economy. In Europe, solid GDP growth driven by a positive operating environment for European companies, especially exporters, has driven unemployment lower and supported growing consumption. Japanese economic growth also continues to make progress, and the country's deflationary problems are gradually receding. Economic growth in emerging market countries remains faster than in the developed world as they persist in "catching up," led by China, which continues its rise as a world economic power. 2 Letter The U.S. Federal Reserve and the world's other central banks have pursued policies aimed at producing low and stable inflation, believed to be the best backdrop for steady economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so central bank policies have also been "investor friendly." The central banks have responded to this past summer's liquidity squeeze in the inter-bank and commercial paper markets by acting as the "lenders of last resort" to limit the risk of problems spreading to the broader economy. Looking forward, the economic outlook and equity valuations appear generally positive, although the current environment is plagued by fears that subprime mortgage problems will result in a systemic liquidity/credit crunch. While falling risk tolerances may depress asset prices in the short term, valuations look reasonable if credit market problems do not spread to the broader economy. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to your particular risk tolerance and investment objective.

Q: How did the U.S. stock market perform during the reporting period, and how did this affect the performance of the Fund? A: Stocks delivered strong overall returns during this interval, masking the fact that the period was made up of two distinct parts. In the first part - covering the span from the Fund's inception through the end of June 2007 - individual stock performance was largely driven by the surge in merger and acquisition activity led by private equity firms, which purchase public companies at a premium in order to take them private. This phenomenon led to strong performance not just for companies that were acquired, but also for those seen as being likely acquisition targets. Since private equity firms tend to focus on companies that are ripe for restructuring - rather than those with the strongest fundamentals - lower-quality companies generally outperformed during this period. Given that our investment style focuses on superior companies with rising market share, a history of consistent earnings growth, and reasonable valuations, most of the stocks held in the Fund's portfolio did not benefit from takeover speculation during this acquisition-fueled rally. Even so, Class A shares of the Fund slightly outperformed the Fund's benchmark, the Russell 3000 Growth Index, from the Fund's inception through the end of June 2007. The second part, beginning in mid-July, saw investors' focus beginning to turn to the U.S. housing market, the problems in the sub-prime mortgage area, and the downturn of the global credit markets. The resulting increase in investors' risk aversion made it more difficult and expensive for private equity firms to borrow money to finance leveraged buyouts. A notable outcome of this shift was the beginning of a period of greater investor interest in higher-quality growth companies such as those held in the Fund. This enabled the Fund to extend its lead in terms of relative performance during the summer months. During the full period, the Class A shares of the Fund returned 11.90%, outpacing the 10.48% return of the benchmark, the Russell 3000 Growth Index. 4 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What factors helped and hurt performance during the reporting period? A: The Fund's performance was helped by the strength of our stock selection in the information technology, consumer discretionary, and industrials sectors. The primary area of underperformance was materials. With respect to individual stocks, the top contributor was Seattle-based Aquantive, an internet marketing company that received a takeover bid from Microsoft in mid-May at a substantial premium. Its shares, which stood at $35.87 on May 17, closed at $63.79 the following day. Eventually, Aquantive was acquired by Microsoft a few months later. Making the second-largest contribution was Gamestop, a retailer that sells new and used video games and consoles. Gamestop has benefited as consumers have upgraded their games following the release of improved systems such as the PS3, Wii, and Xbox 360. The company has executed its business plan very well, and we believe more upside is ahead. Precision Castparts also was a strong performer for the Fund. A manufacturer of highly engineered industrial parts, the company has benefited from strong demand for cost efficient new planes like the Boeing 787, new airplane orders from emerging markets like China, and the need for replacements in aging fleets. Rounding out the list of leading contributors was Dade Behring, a maker of diagnostic lab equipment that was acquired by Siemens at a 30% premium in the final month of the reporting period; and Apple Computer, which has enjoyed strong sales across all of its product lines. We discuss the latter in greater detail below. The Fund's worst performer was Caremark Rx, now known as CVS Caremark following its merger with CVS. We believed this merger failed to appropriately value Caremark given its long track record 5 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 8/31/07 (continued) - -------------------------------------------------------------------------------- of effective execution and strong market performance. Given our concerns regarding the earnings outlook for the combined company, we elected to sell the stock in January. The second-largest detractor was Palomar Medical Technologies, a developer of laser-based hair removal systems. Although we believe the company's longer-term earnings prospects from joint ventures with Gillette and Johnson & Johnson are attractive, we elected to sell the stock based on our concerns about the likely slowing of Palomar's sales and profits. Also in the health care sector, Genentech underperformed due to investor worries about increased competition for several of its drugs. However, due to Genentech's outstanding pipeline of new drugs and our expectation that its leading cancer drug, Avastin, will continue to drive strong earnings growth, we decided to maintain the Fund's position as of the end of the reporting period. Q: In what areas have you been finding opportunities? A: The underperformance of higher-quality stocks throughout much of the past year afforded us the opportunity to purchase attractively-valued shares in the types of companies we favor. For instance, we added two technology companies - Adobe Systems and Apple - during pullbacks in the broader market. We believe Adobe will benefit from the introduction of the new Creative Suite 3 (CS3) product targeted to advertising firms. Adobe purchased the software company Macromedia in 2005, and CS3 is the first product release from the merged company. CS3 allows customers to create print and video media for the Internet and is Adobe's largest product launch ever. Apple, meanwhile, may be best known for its success in selling the iPod and iPhone, but it is also enjoying success selling its Mac computers. The Mac is especially popular with advertisers and design professionals, and we believe its sales will benefit further from the Adobe upgrade cycle. Since Apple has only a 4% to 5% market share in computers, even a small increase in this percentage would have a large impact on the company's earnings. We purchased Apple early in 2007, and the stock has already performed well for the Fund. We recently invested in Celgene, a biotechnology company with a very promising cancer drug called Revlimid. The drug has proven to be effective at fighting blood cancers, and there is evidence that it may work in treating solid tumors as well. We believe 6 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Revlimid has tremendous potential, which could result in rapid earnings growth for Celgene. IntercontinentalExchange, which operates an Internet-based global electronic marketplace for trading futures and commodities, is another new investment for the Fund. We initiated a position during the March correction in the broader market, giving us the opportunity to purchase shares at about a 20% discount from their previous highs. The company is a proven leader in the nascent over-the-counter (OTC) market for electronic trading of numerous commodities, including oil and natural gas. This market is expanding rapidly and we believe Intercontinental will be the main beneficiary among the exchanges. Q: What is your outlook for growth stocks? A: We expect that the overall market environment will continue to be characterized by worries about how the disruptions in the housing and credit markets will affect consumer spending and the U.S. economy as a whole. While we also believe overall corporate earnings growth will continue to slow, we expect continued strength in corporate spending will allow the U.S. economy to avoid a recession. On balance, we are cautiously optimistic based on positive corporate earnings prospects, the reasonable valuation level of the broader market, and our outlook for Federal Reserve policy. In our view, these factors point to a backdrop of slowing top-line sales and decreasing profit margins. In this environment, companies that can consistently deliver strong earnings growth likely will be harder to find - and thus be awarded higher valuations. We therefore believe the stage is set for higher-quality growth companies that exhibit superior sales and earnings growth to outperform the overall market, which could be beneficial for the Fund. 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. 7 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 8/31/07 (continued) - -------------------------------------------------------------------------------- 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 Oak Ridge Large Cap Growth Fund Based on actual returns from March 1, 2007 through August 31, 2007 Actual Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value On 3/1/07 Ending Account $1,085.35 $1,080.74 $1,088.52 Value On 8/31/07 Expenses Paid $ 6.57 $ 11.28 $ 6.58 During Period* * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%, and 1.25%, for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the half year period). 14 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- 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.

Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 - -------------------------------------------------------------------------------- 1. 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. Information regarding the Fund's principal risks are contained in the Fund's prospectus. Please refer to those documents when considering the Fund's 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 27 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- trading on the Exchange. 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 also may 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, 2007, 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 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. 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 either from or in excess of net investment income or net 28 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The Fund has reclassified $7,187 to decrease accumulated net investment loss, $5,749 to decrease accumulated net realized loss on investments and $1,438 to decrease paid-in capital 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. There were no distributions paid during the period ended August 31, 2007. The following shows the components of distributable earnings on a federal income tax basis at August 31, 2007. - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Unrealized appreciation $169,054 -------- Total $169,054 ======== - -------------------------------------------------------------------------------- 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 UniCredito Italiano S.p.A. (UniCredito Italiano), earned approximately $966 in underwriting commissions on the sale of Class A shares for the period ended August 31, 2007. D. Class Allocations 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 29 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- Note 3). 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. 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 fees. E. 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. 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 of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will 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 the Securities Lending Investment Fund, which is sponsored by Brown Brothers Harriman & Co., the Fund's custodian. 2. Management Agreement PIM, a wholly owned subsidiary of UniCredito Italino, 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 period. 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 30 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- January 1, 2009 for Class A shares and through January 1, 2008 for Class C shares. There is no expense limitation in effect for Class Y 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. On August 31, 2007, $41 was payable to PIM related to management fees, administrative costs and certain other services, and is included in due to affiliates. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates is $447 in transfer agent fees payable to PIMSS at August 31, 2007. 4. Distribution and Service 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. Pursuant to the Class A Plan, the Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of 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 $24 in distribution fees payable to PFD at August 31, 2007. 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 period ended August 31, 2007, no CDSCs were paid to PFD. 31 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- 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 period ended August 31, 2007, the Fund's expenses were not reduced under such arrangement. 6. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of no later than February 29, 2008. At this time, management is evaluating the implications of FIN 48 and any impact in the financial statements has not yet been determined. 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. 32 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Oak Ridge All Cap Growth Fund: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Oak Ridge All Cap Growth Fund (the Fund) (one of the portfolios constituting Pioneer Series Trust V) as of August 31, 2007, and the related statement of operations, the statement of changes in net assets, and the financial highlights for the period from October 17, 2006 (Commencement of Operations) to August 31, 2007. 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 audit. We conducted our audit 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 audit 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, 2007, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audit provides 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 Oak Ridge All Cap Growth Fund at August 31, 2007, the results of its operations, the changes in its net assets, and the financial highlights for the period from October 17 (Commencement of Operations) to August 31, 2007, in conformity with U.S. generally accepted accounting principles. /s/Ernst + Young LLP Boston, Massachusetts October 12, 2007 33 Pioneer Oak Ridge All Cap Growth Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.

They were particularly useful guides during the past year, when an otherwise healthy long-term bull market was buffeted by problems in the mortgage and banking industries. Since mid-year, issues tied to poor underwriting practices in the subprime sector of the mortgage industry, and to problems with risk management by banks and hedge funds, have resulted in increased market volatility and rising concern about risks to U.S. economic growth. Even against this backdrop, the long-term performance of major asset classes remained positive. In the 12 months ending August 31, 2007, equity investors were generally rewarded as, despite a late-July decline, the Standard & Poor's 500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the NASDAQ Composite Index returned 19%. International developed and emerging markets equities performed well also, with the MSCI EAFE Developed Market Index returning 19% and the MSCI Emerging Markets Index returning 44% over the 12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 7% for the same period, reflecting its higher coupon yield. U.S. economic growth has slowed in the past year, but this was due as much to the natural maturation of the cyclical expansion, as U.S. factories approached full utilization and the labor market approached full employment, as it was to rising commodity prices and short-term interest rates. This slowdown was, therefore, not entirely unwelcome, as it reduced the threat of higher inflation. More recently, however, there has been increasing concern that falling home prices and/or banks' unwillingness to lend pose a larger and more imminent threat to the economy. In Europe, solid GDP growth driven by a positive operating environment for European companies, especially exporters, has driven unemployment lower and supported growing consumption. Japanese economic growth also continues to make progress, and the country's deflationary problems are gradually receding. Economic growth in emerging market countries remains faster than in the developed world as they persist in "catching up," led by China, which continues its rise as a world economic power. 2 Letter The U.S. Federal Reserve and the world's other central banks have pursued policies aimed at producing low and stable inflation, believed to be the best backdrop for steady economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so central bank policies have also been "investor friendly." The central banks have responded to this past summer's liquidity squeeze in the inter-bank and commercial paper markets by acting as the "lenders of last resort" to limit the risk of problems spreading to the broader economy. Looking forward, the economic outlook and equity valuations appear generally positive, although the current environment is plagued by fears that subprime mortgage problems will result in a systemic liquidity/credit crunch. While falling risk tolerances may depress asset prices in the short term, valuations look reasonable if credit market problems do not spread to the broader economy. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to your particular risk tolerance and investment objective.

This dramatic shift in the investment environment was brought on by fears about the subprime mortgage industry and the potential impacts the industry's problems might have on the larger economy. In the following interview, members of the team responsible for managing Pioneer Select Research Growth Fund review the 12 months ending August 31, 2007. Diego Franzin, Ashesh Savla and John Peckham, CFA, discuss the factors that affected Fund performance during the 12 months. Mr. Franzin is Head of Pioneer's U.S. Quantitative Research & Management Group, Mr. Savla, is a Quantitative Analyst at Pioneer, and Mr. Peckham is Pioneer's Head of U.S. Equity Research. Q: How did the Fund perform during the 12 months ending August 31, 2007? A: Pioneer Select Research Growth Fund performed very well for the period, outpacing both its index and its competitive funds' peer group average. For the 12 months ending August 31, 2007, the Fund's Class A shares had a total return of 20.69%, at net asset value. During the same fiscal year, the benchmark Russell 1000 Growth Index returned 17.70%, and the average return of the 727 funds in Lipper's Large Cap Growth Fund category was 16.96%. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What were the principal factors that influenced the Fund's performance during the 12 months? A: The Fund did well relative to its benchmark both when stocks rose during the 10 months -- from August 31, 2006 through June 30, 2007 -- and when the market became more volatile during July and August 2007. Stock selection was the key driver, consistent with 4 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- the Fund's distinctive discipline. We typically maintain investments in 50 different companies selected from the 100 stocks in the Pioneer Research Fund portfolio. Sector weightings are equal to those of the Russell 1000 Growth Index, but we choose individual holdings from among all eligible stocks, whether part of the growth or value universe. In this process, we rank stocks based on our research into the superior characteristics of companies in 17 different sectors and industries. We believe the advantage of this process lies in its combination of both quantitative and qualitative research techniques. For example, when purely quantitative mutual funds in general struggled late in the fiscal year, this Fund enjoyed its best period relative to the Russell 1000 Growth Index. Q: What types of investments had the greatest influence on performance? A: Our selections in the health care, information technology and industrials sectors had the greatest positive impacts on results relative to the Russell 1000 Growth Index. On the negative side, our picks in the materials, financials and consumer staples sectors modestly underperformed the results in the same sectors in the Russell benchmark. In health care, the leading performers were pharmaceutical company Schering Plough and biotechnology leader Amgen. In addition, the fact that we did not own any shares of Johnson & Johnson - a major part of the Russell index - helped relative performance when that company performed poorly. Schering Plough gained in value as investors became more optimistic about its development pipeline of potential new drug products. We owned Amgen early in the year, when it performed very well, and then sold it before its stock price fell because of problems with an important anemia drug. Among our technology holdings, the top performers were Cisco Systems and Freescale Semiconductor. Cisco was the beneficiary of the continued expansion of corporate spending on information technology networks, while Freescale was bought out at a premium price by private equity investors. In the industrials sector, leading performers were equipment manufacturer Terex and railroad corporation Norfolk Southern. Terex, whose products include trucks and other heavy equipment used by industrial and utility corporations, performed well in the latter 5 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 8/31/07 (continued) - -------------------------------------------------------------------------------- stages of the current business cycle, while Norfolk Southern's earnings grew from strong demand for rail transportation services. In our materials selections, we did not own enough commodities companies - especially steel and other mining and minerals companies - during a period in which they performed very well. At the same time, we had too large a position in weak-performing Dow Chemical. Nevertheless, we did have an investment in Freeport McMoran Copper and Gold, a stellar performer for the period. In the financials sector, we had a large position in brokerage and investment banking leader Merrill Lynch, whose share price was affected by concerns about the health of corporate financing in the wake of the subprime mortgage crisis. In the consumer staples area, a notable underperformer was Church & Dwight, producer of a variety of personal care consumer products. We have maintained our position in the company as we believe that its fundamentals have remained sound, despite the underperformance. Q: What is your investment outlook? A: We remain optimistic about prospects in the market for several reasons: the economy has remained in its growth trajectory; both interest rates and inflation remain low by historical measures; and stock valuations appear reasonable. While the slump in the housing industry has been a drag on the economy, we do not believe it will pull the economy into a recession. Overall, we think the market continues to afford good opportunities for stock investing. 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.

Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. NAV results represent the percent change in net asset value per share. Returns would have been lower had sales charges been reflected. POP returns reflect deduction of maximum 5.75% sales charge. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. 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 1/1/09 for Class A 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 an Index. 10 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- 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.

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.

Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 - -------------------------------------------------------------------------------- 1. Organization and Significant Accounting Policies 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. 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). To date, no shares have been offered to the public. The Fund shares outstanding at August 31, 2007, are owned by PFD. The Fund's investment objective is long-term capital growth. 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. Information regarding the Fund's principal investment risks is contained in the Fund's prospectus. Please refer to that document when considering the Fund's investment 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: 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 23 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- 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 also may 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, 2007, 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 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. 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 either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. 24 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- At August 31, 2007, the Fund reclassified $73 to decrease distributions in excess of net investment income and $73 to decrease accumulated net realized gain on investments. 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 tax character of distributions paid during the year ended August 31, 2007 was as follows. There were no distributions paid during the period ended August 31, 2006. - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Ordinary income $ 1,640 Long term capital gain - -------- Total $ 1,640 ======== - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at August 31, 2007: - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Undistributed ordinary income $ 38,811 Undistributed long-term gain 7,790 Unrealized appreciation 66,026 -------- Total $112,627 ======== - -------------------------------------------------------------------------------- C. 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. 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 of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the 25 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in the Securities Lending Investment Fund, which is sponsored by Brown Brothers Harriman & Co., the Fund's custodian. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredito Italiano, 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, 2007, the net management fee was equivalent to 0.75% of the average daily net assets. Through January 1, 2009, PIM has agreed not to impose its management fee and to assume other operating expenses of the Fund to the extent necessary to limit Class A expenses to 1.25% of the average daily net assets attributable to Class A shares. In addition, under the management and administration agreements, certain other services, including accounting, regulatory reporting and insurance, are paid by the Fund. At August 31, 2007, $231 was payable to PIM related to management fees, administrative costs and certain other services and is included in due to affiliates. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates is $17 in transfer agent fees payable to PIMSS at August 31, 2007. 4. Distribution Plan The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the Investment Company Act of 1940. The Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of Class A shares. There were no distribution fees payable to PFD at August 31, 2007. 26 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 5. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of no later than February 29, 2008. At this time, management is evaluating the implications of FIN 48 and any impact in the financial statements has not yet been determined. In addition, 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. 27 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Select Research Growth Fund: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Select Research Growth Fund (the Fund) (one of the portfolios constituting Pioneer Series Trust V) as of August 31, 2007, 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, 2007, by correspondence with the custodian and brokers. 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 Select Research Growth Fund at August 31, 2007, 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 12, 2007 28 Pioneer Select Research Growth Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.

They were particularly useful guides during the past year, when an otherwise healthy long-term bull market was buffeted by problems in the mortgage and banking industries. Since mid-year, issues tied to poor underwriting practices in the subprime sector of the mortgage industry, and to problems with risk management by banks and hedge funds, have resulted in increased market volatility and rising concern about risks to U.S. economic growth. Even against this backdrop, the long-term performance of major asset classes remained positive. In the 12 months ending August 31, 2007, equity investors were generally rewarded as, despite a late-July decline, the Standard & Poor's 500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the NASDAQ Composite Index returned 19%. International developed and emerging markets equities performed well also, with the MSCI EAFE Developed Market Index returning 19% and the MSCI Emerging Markets Index returning 44% over the 12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 7% for the same period, reflecting its higher coupon yield. U.S. economic growth has slowed in the past year, but this was due as much to the natural maturation of the cyclical expansion, as U.S. factories approached full utilization and the labor market approached full employment, as it was to rising commodity prices and short-term interest rates. This slowdown was, therefore, not entirely unwelcome, as it reduced the threat of higher inflation. More recently, however, there has been increasing concern that falling home prices and/or banks' unwillingness to lend pose a larger and more imminent threat to the economy. In Europe, solid GDP growth driven by a positive operating environment for European companies, especially exporters, has driven unemployment lower and supported growing consumption. Japanese economic growth also continues to make progress, and the country's deflationary problems are gradually receding. Economic growth in emerging market countries remains faster than in the developed world as they persist in "catching up," led by China, which continues its rise as a world economic power. 2 Letter The U.S. Federal Reserve and the world's other central banks have pursued policies aimed at producing low and stable inflation, believed to be the best backdrop for steady economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so central bank policies have also been "investor friendly." The central banks have responded to this past summer's liquidity squeeze in the inter-bank and commercial paper markets by acting as the "lenders of last resort" to limit the risk of problems spreading to the broader economy. Looking forward, the economic outlook and equity valuations appear generally positive, although the current environment is plagued by fears that subprime mortgage problems will result in a systemic liquidity/credit crunch. While falling risk tolerances may depress asset prices in the short term, valuations look reasonable if credit market problems do not spread to the broader economy. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to your particular risk tolerance and investment objective.

The late-period market turmoil was brought on by fears about the subprime mortgage industry and its potential impacts on the larger economy. In the following interview, members of the team responsible for managing Pioneer Select Research Value Fund review the 12 months ending August 31, 2007. Diego Franzin, Ashesh Savla and John Peckham, CFA, discuss the factors that affected Fund performance. Mr. Franzin is Head of Pioneer's U.S. Quantitative Research & Management Group, Mr. Savla, is a Quantitative Analyst at Pioneer, and Mr. Peckham is Pioneer's Head of U.S. Equity Research. Q: How did the Fund perform during the 12 months ending August 31, 2007? A: The Fund did very well. For the 12 months ending August 31, 2007, Pioneer Select Research Value Fund's Class A shares had a total return of 16.24%, at net asset value. During the same fiscal year, the benchmark Russell 1000 Value Index returned 12.85%, and the average return of the 497 funds in Lipper's Large Cap Value Fund category was 13.54%. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What were the principal factors that influenced the Fund's performance during the 12 months? A: The Fund did well relative to its benchmark both when stocks rose during the 10 months - from August 31, 2006 through June 30, 2007 - and when the market became more volatile during July and August 2007. Stock selection was the key driver, consistent with the Fund's distinctive discipline. We typically maintain investments in 50 different companies selected from the 100 stocks in the 4 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Pioneer Research Fund portfolio. Sector weightings are equal to those of the Russell 1000 Value Index, but we choose individual holdings from among all eligible stocks, whether part of the growth or value universe. In this process, we rank stocks based on our research into the superior characteristics of companies in 17 different sectors and industries. We believe the advantage of this process lies in its combination of both quantitative and qualitative research techniques. For example, when purely quantitative mutual funds in general struggled late in the fiscal year, this Fund enjoyed its best period relative to the Russell 1000 Value Index. Q: What types of investments had the greatest influence on performance? A: Our selections in nine of the 10 market sectors outperformed the comparable group in the Russell 1000 Value Index. The top performing sectors in the Fund, relative to the benchmark, were health care, energy and financials. The top individual contributor was a health care company, Bristol-Myers Squibb. This global pharmaceutical company has an excellent pipeline of new drugs under development. In addition, the company came to be viewed as an attractive potential acquisition by a larger corporation. Also helping relative performance in the health care sector was our decision to avoid owning shares of Pfizer, another pharmaceutical company that performed poorly. In energy, three holdings in particular had outstanding performance. Marathon Oil's share price rose because of its strong position in the U.S. refining industry during a period of rising profitability for oil refiners. Weatherford International, an oil field services company, benefited from its leadership in new technologies that help oil companies increase their yields from individual wells. Finally, Chevron - a company whose stock we had purchased at a very attractive price - outperformed as it exceeded earnings expectations. In the financials sector, the leading performer was asset manager Franklin Resources, which gained as its mutual funds attracted a healthy flow of new investments. The only sector that underperformed relative to the benchmark index was materials. In that area, the problem was that we did not own enough commodities companies - especially steel and other 5 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 8/31/07 (continued) - -------------------------------------------------------------------------------- mining and minerals companies - during a period in which they performed very well. Q: What is your investment outlook? A: We remain optimistic about prospects in the market for several reasons: the economy has remained in its growth trajectory; both interest rates and inflation remain low by historical measures; and stock valuations appear reasonable. While the slump in the housing industry has been a drag on the economy, we do not believe it will pull the economy into a recession. Overall, we think the market continues to afford good opportunities for stock investing. 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.

Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. NAV results represent the percent change in net asset value per share. Returns would have been lower had sales charges been reflected. POP returns reflect deduction of maximum 5.75% sales charge. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. 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 1/1/09 for Class A 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(R) Value Index measures the performance of large-cap U.S. value 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 the Index. 9 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- 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 Select Research Value Fund Based on actual returns from March 1, 2007 through August 31, 2007 Share Class A - -------------------------------------------------------------------------------- Beginning Account Value On 3/1/07 $1,000.00 Ending Account Value On 8/31/07 $1,060.10 Expenses Paid During Period* $ 6.49 * Expenses are equal to the Fund's annualized expense ratio of 1.25% for Class A shares, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). 10 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. Expenses Paid on a $1,000 Investment in Pioneer Select Research Value Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from March 1, 2007 through August 31, 2007 Share Class A - -------------------------------------------------------------------------------- Beginning Account Value On 3/1/07 $1,000.00 Ending Account Value On 8/31/07 $1,018.90 Expenses Paid During Period* $ 6.36 * Expenses are equal to the Fund's annualized expense ratio of 1.25% for Class A shares, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). 11 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- SCHEDULE OF INVESTMENTS 8/31/07 - -------------------------------------------------------------------------------- Shares Value COMMON STOCKS - 99.3% Energy - 13.7% Integrated Oil & Gas - 9.6% 282 Chevron Corp. $ 24,748 271 ConocoPhillips 22,192 198 USX-Marathon Group, Inc. 10,670 -------- $ 57,610 -------- Oil & Gas Equipment & Services - 1.9% 189 Weatherford International, Inc.* $ 11,034 -------- Oil & Gas Exploration & Production - 2.2% 172 Apache Corp. $ 13,309 -------- Total Energy $ 81,953 -------- Materials - 3.9% Diversified Chemical - 3.1% 284 Dow Chemical Co. $ 12,107 85 PPG Industries, Inc. 6,235 -------- $ 18,342 -------- Steel - 0.8% 94 Nucor Corp. $ 4,973 -------- Total Materials $ 23,315 -------- Capital Goods - 9.0% Aerospace & Defense - 4.9% 183 Northrop Grumman Corp. $ 14,428 198 United Technologies Corp. 14,776 -------- $ 29,204 -------- Electrical Component & Equipment - 1.0% 113 Thomas & Betts Corp.* $ 6,259 -------- Industrial Conglomerates - 3.1% 157 3M Co. $ 14,285 97 Tyco International, Ltd. 4,284 -------- $ 18,569 -------- Total Capital Goods $ 54,032 -------- 12 The accompanying notes are an integral part of these financial statements.

Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 - -------------------------------------------------------------------------------- 1. Organization and Significant Accounting Policies Pioneer 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. 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). To date, no shares have been offered to the public. The Fund shares outstanding at August 31, 2007, are owned by PFD. The Fund's investment objective is to seek long-term capital growth. 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. Information regarding the Fund's principal investment risks is contained in the Fund's prospectus. Please refer to that document when considering the Fund's investment 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: 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, 21 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- 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 also may 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, 2007, 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 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. 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 either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. At August 31, 2007, the Fund reclassified $2 to decrease undistributed net investment income and $2 to increase accumulated 22 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- net realized gain on investments. 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 tax character of distributions paid during the year ended August 31, 2007 was as follows. There were no distributions paid during the period ended August 31, 2006. - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Ordinary Income $20,265 Long-term capital gain - ------- Total $20,265 ======= - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at August 31, 2007: - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Undistributed ordinary income $20,911 Undistributed long-term gain 18,526 Unrealized appreciation 60,263 ------- Total $99,700 ======= - -------------------------------------------------------------------------------- The difference between book basis and tax basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. 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. 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 of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the 23 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 8/31/07 (continued) - -------------------------------------------------------------------------------- lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in the Securities Lending Investment Fund, which is sponsored by Brown Brothers Harriman & Co., the Fund's custodian. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredito Italiano, 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, 2007, the management fee was equal to 0.75% of the Fund's average daily net assets. Through January 1, 2009, 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 Class A expenses to 1.25% of the average daily net assets attributable to Class A shares. In addition, under the management and administration agreements, certain other services, including accounting, regulatory reporting and insurance, are paid by the Fund. There were no management fees, administrative costs or other services payable at August 31, 2007. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates is $26 in transfer agent fees payable to PIMSS at August 31, 2007. 4. Distribution Plan The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the Investment Company Act of 1940. The Fund will pay PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of Class A shares. There were no distribution fees payable to PFD at August 31, 2007. 24 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 5. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of no later than February 29, 2008. At this time, management is evaluating the implications of FIN 48 and any impact in the financial statements has not yet been determined. In addition, 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. 25 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Select Research Value Fund: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Select Research Value Fund (the Fund) (one of the portfolios constituting Pioneer Series Trust V) as of August 31, 2007, 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, 2007, by correspondence with the custodian and brokers. 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 Select Research Value Fund at August 31, 2007, 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 12, 2007 26 Pioneer Select Research Value Fund - -------------------------------------------------------------------------------- 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.
