Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we 2 Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Respectfully, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 3 Portfolio Management Discussion | 2/28/09 Stock prices plummeted, with many market indices losing 40% or more of their value, during the six-month period ended February 28, 2009, amid growing evidence that the U.S. economy was sinking into a serious recession. In the following discussion, Pioneer's Diego Franzin, Ashesh Savla and John Peckham, review the factors that affected the performance of Pioneer Disciplined Growth Fund during this six-month period. Mr. Franzin is Head of Global Quantitative Research & Management at Pioneer; Mr. Savla is a Quantitative Analyst at Pioneer; and Mr. Peckham, CFA, is Head of Pioneer's Global Fundamental Research Group. All are members of the Fund's management team. Q How did Pioneer Research Growth Fund perform during the six months ended February 28, 2009? A The Fund's Class A shares returned -37.47% at net asset value for the six months ended February 28, 2009, while the Fund's benchmark, the Russell 1000 Growth Index, returned -39.90%. During the same period, the average return of the 846 funds in Lipper's Large Cap Growth category was -40.13%. Q What were the principal factors affecting the Fund's performance during the six months ended February 28, 2009? A Stocks were battered during the six-month period, as the financials sector imploded and credit markets came close to seizing up. Most stocks suffered substantial price losses as investors attempted to avoid risk. The Standard & Poor's 500 Index and the Russell 1000 Index, two common benchmarks for large-cap stocks, declined by 41.79% and 42.25%, respectively, while many small-cap and mid-cap indices fell by even more. Growth-stock benchmarks tended to do better than value-stock indices, but this was principally because the value indices maintained greater weightings in financials stocks, which were the most exposed to the credit crisis and tended to underperform the overall market. The dismal investment results came amid a drumbeat of evidence that the nation's economy had entered into recession. The Commerce Department's announcement that gross domestic product (GDP) had begun to contract followed months of reports of declining corporate profits, rising unemployment, falling commodity prices and widespread uncertainties about the nation's economic policy responses. In this difficult environment, the Fund did not escape the market downdraft, and we are disappointed with its performance results. However, the Fund did manage to outperform its benchmark, the Russell 1000 Growth Index (the Russell Index), during the six-month period ended February 28, 4 Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 2009. The Fund's performance edge over the benchmark was due primarily to stock selection, especially in the industrials, information technology and financials sectors. In general, we successfully avoided some of the biggest blowups in the market, as the Fund had no investments in many of the worst-performing stocks in the Russell Index, including Citigroup, American International Group and General Electric. On the negative side, our modest underweighting of the Fund in the consumer staples sector was somewhat of a performance detractor, and stock selections in health care and energy also held back Fund results relative to the Russell Index. We maintained a relatively conservative positioning for the Fund's portfolio, emphasizing investments in corporations with strong balance sheets and with relatively low exposure to the deteriorating credit markets. The Fund maintained a portfolio of stocks in about 50 different companies. The stocks are selected with the help of qualitative research analysis and quantitative analytical tools. Q What were some of the individual investments that most affected the Fund's results relative to the Russell 1000 Growth Index during the six months ended February 28, 2009? A In the poor-performing financials sector, the Fund generally avoided the most prominent stock price collapses. It had no investments at all in such companies as Citigroup, American International Group, Merrill Lynch, Lehman Brothers (which filed for bankruptcy), Fannie Mae or Freddie Mac. The Fund's positions in financials stocks, The Travelers Companies and Intercontinental Exchange held up better than the overall sector. Travelers is primarily a property-and-casualty insurer that avoided many of the problems incurred by life insurers, while Intercontinental Exchange operates global commodity and financial products marketplaces. In the industrials sector, the Fund's lack of exposure to General Electric (GE) was a significant help. We avoided GE because of our concerns about the vulnerability of its financial services businesses, which has accounted for approximately 50% of its profits. Two of the Fund's industrials holdings that outperformed were UPS and SPX. Delivery corporation UPS is a high-quality company that performed reasonably well compared to the overall sector. SPX is a diversified corporation that appears well positioned to benefit from increased investments in energy infrastructure because of its operations producing equipment for energy transmission systems. Among the Fund's information technology holdings, the best performer was Apple, which was the Fund's top individual contributor to performance during the six-month period ended February 28, 2009. Apple was helped by a very strong product line across all of its markets. Even in a slowing economy, Apple gained market share in the personal computer market, Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 5 while its new 3G iPhone product was a big winner in the highly competitive wireless communications hand-set business. Stock selections in health care and energy were not as successful. In health care, the Fund's positions in Cigna, an HMO, and Thermo Fisher, which produces a variety of products used by health care services providers, both yielded particularly disappointing results during the period. The share price of Cigna was pulled down both by higher-than-expected operating costs and by investor concerns that the potential health care policies of the new Obama administration might affect profits of managed health care companies. Thermo Fisher had a relatively high valuation that suffered as the company's profit growth began to slow. In energy, two notable poor-performing investments were Weatherford International and El Paso. Weatherford, an oil field services company, was removed as a component of the Standard & Poor's 500 Index, which led to share price losses as index funds sold their positions. In addition, investors became concerned about the outlook for oil field services companies due to falling oil prices. El Paso is the largest natural gas pipeline operator in the United States and is also a major exploration and production company. Its price fell on investor concerns about its large debt load and its need to issue additional bonds at a time when the credit markets were under stress. Conversely, the Fund had an underweighted position in ExxonMobil, which hurt relative performance as the giant, integrated oil company was able to withstand the effects of falling oil prices better than most energy corporations. Q What is your investment outlook? A We intend to continue to maintain a relatively defensive portfolio for the Fund, even as we look for an eventual improvement in overall market conditions. In particular, we expect to be cautious in investments in those sectors that make up major parts of the Russell 1000 Growth Index, including the information technology, health care and industrials groups. In information technology, we expect to favor investments in companies such as Oracle and Cisco Systems, whose principal customers are corporations rather than consumers. In health care, we expect to focus on stocks of companies with steady revenues. In addition, we anticipate de-emphasizing the managed health care industry. In industrials, we anticipate favoring highly diversified corporations, including those in the defense-related industries, while generally avoiding corporations that have significant exposure to the financial services businesses. We expect that individual stock-picking should continue to drive Fund performance. 6 Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 Please refer to the Schedule of Investments on pages 15-19 for a full listing of Fund securities. Investing in small and mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. 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. These opinions should not be relied upon for any other purposes. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Research Value Fund Based on actual returns from September 1, 2008 through February 28, 2009. - -------------------------------------------------------------------------------- Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 9/1/08 - -------------------------------------------------------------------------------- Ending Account Value $625.30 $622.90 $626.30 (after expenses) on 2/28/09 - -------------------------------------------------------------------------------- Expenses Paid $5.04 $8.65 $3.63 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%, and 0.90% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 13 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 Research Growth Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from September 1, 2008 through February 28, 2009. - -------------------------------------------------------------------------------- Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 9/1/08 - -------------------------------------------------------------------------------- Ending Account Value $1,018.60 $1,014.13 $1,020.33 (after expenses) on 2/28/09 - -------------------------------------------------------------------------------- Expenses Paid $6.26 $10.74 $4.51 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%, and 0.90% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 14 Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 Schedule of Investments | 2/28/09 (unaudited) - --------------------------------------------------------- Shares Value - --------------------------------------------------------- COMMON STOCKS -- 96.0% ENERGY -- 8.2% Integrated Oil & Gas -- 1.9% 206 Exxon Mobil Corp. $13,987 - --------------------------------------------------------- Oil & Gas Drilling -- 1.9% 246 Transocean, Ltd. * $14,703 - --------------------------------------------------------- Oil & Gas Equipment & Services -- 1.0% 738 Weatherford International, Inc. * $ 7,874 - --------------------------------------------------------- Oil & Gas Exploration & Production -- 3.4% 179 Apache Corp. $10,577 486 XTO Energy, Inc. 15,387 ------- $25,964 ------- Total Energy $62,528 - --------------------------------------------------------- MATERIALS -- 4.1% Fertilizers & Agricultural Chemicals -- 4.1% 258 Monsanto Co. $19,678 137 Potash Corp.

Organization and Significant Accounting Policies Pioneer Disciplined Growth Fund, formerly Pioneer Research Growth Fund, (the Fund) is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund was organized on October 12, 2005, and commenced operations on December 15, 2005. The Fund's investment objective is long-term capital growth. The Fund offers three classes of shares designated as Class A, Class C and Class Y shares. Class C and Class Y shares were first publicly offered on July 17, 2008 and July 31, 2008, respectively. Each class of shares represents and interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income, and therefore, the payment of different dividends by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Share classes have exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectuses contain unaudited information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 27 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, are valued at the mean between the last bid and asked prices. Securities for which market prices and/or quotations are not readily available are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use fair value methods to value 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 February 28, 2009, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years are subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net 28 Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions paid will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended August 31, 2008 was as follows: - -------------------------------------------------------------------------------- 2008 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $42,593 Long term capital gain 16,052 - -------------------------------------------------------------------------------- Total $58,645 ================================================================================ The following shows the components of distributable earnings on a federal income tax basis at August 31, 2008: - -------------------------------------------------------------------------------- 2008 - -------------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 1,615 Post-October loss deferred (16,877) Unrealized appreciation 16,780 - -------------------------------------------------------------------------------- Total $ 1,518 ================================================================================ C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $20 in underwriting commissions on the sale of Class A shares during the six months ended February 28, 2009. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on their respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 29 in the same manner and at the same time, except that Class A, Class C, and Class Y shares bear different transfer agent and distribution expense rates. E. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary cash investments. Credit Suisse, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund will be required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.65% of the Fund's average daily net assets up to $1 billion, 0.60% of the next $4 billion and 0.55% on assets over $5 billion. Prior to September 1, 2008, the Fund's management fee was 0.75% of the Fund's average daily net assets up to $1 billion and 0.70% on assets over $1 billion. For the six months ended February 28, 2009, the effective management fee (net of waivers and/or assumption of expenses) was equivalent to 0.65% of the Fund's average net assets. Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.25%, 2.15% and 0.90% of the average daily net assets attributable to Class A, Class C and Class Y shares, respectively. These expense limitations are in effect through January 1, 2012 for Class A shares and through January 1, 2010 for Class C and 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. There were no management fees, administrative costs or other services payable to PIM at February 28, 2009. 30 Pioneer Disciplined Growth Fund | Semiannual Report | 2/28/09 3.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we see potential chances for making money in many corners of the market, it takes 2 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 3 Portfolio Management Discussion | 2/28/09 The domestic stock market lost approximately 40% of its value during the six- month period ended February 28, 2009, as investor confidence collapsed in the face of mounting evidence of a deteriorating U.S. economy. In the following discussion, Pioneer's Diego Franzin, Ashesh Savla and John Peckham review the factors that affected the performance of Pioneer Disciplined Value Fund during the six-month period. Mr. Franzin is Head of Global Quantitative Research & Management at Pioneer; Mr. Savla is a Quantitative Analyst at Pioneer; and Mr. Peckham, CFA, is Head of Pioneer's Global Fundamental Research Group. All are members of the Fund's management team. Q How did Pioneer Disciplined Value Fund perform during the six months ended February 28, 2009? A The Fund's Class A shares returned -36.62% at net asset value for the six months, while the Fund's benchmark, the Russell 1000 Value Index, returned -44.71%. During the same six-month period, the 625 funds in Lipper's Large Cap Value category posted an average return of -42.36%. Q What were the principal factors affecting the Fund's performance during the six months ended February 28, 2009? A As the credit markets came close to freezing up and the financials sector imploded, the equity market underwent waves of fierce selling that drove stock prices down substantially during the six months ended February 28, 2009. The Standard & Poor's 500 Index and the Russell 1000 Index, two common benchmarks for large-cap stocks, declined by 41.79% and 42.25%, respectively, during the period, while many small-cap and mid-cap indices fell by even more. Value stock indices, primarily because of their heavier weightings in financials stocks, tended to underperform growth-stock benchmarks. The dismal results came amid disappointing news about the U.S. economy. The U.S. Commerce Department announced that the nation's gross domestic product (GDP) had begun to contract. Meanwhile, a drumbeat of reports continued telling a story of declining profit growth, rising unemployment, falling commodity prices and widespread uncertainty about the nation's economic policy responses. In this difficult market, the Fund was not immune to the downward pull of stock prices, and we are disappointed with its performance results. But the Fund did manage to outperform its benchmark, the Russell 1000 Value Index (the Russell Index), over the six-month period ended February 28, 2009. The Fund's performance edge over the benchmark was due primarily 4 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 to stock selection, especially in the financials, industrials and consumer discretionary sectors. In general, we successfully avoided some of the biggest blowups in the market. The Fund had no investments, for example, in such notably poor performers as Bank of America, Citigroup, American International Group and General Electric. On the negative side, stock selections in health care and energy tended to detract from the Fund's results relative to the Russell Index. We maintained a relatively defensively positioned portfolio over the six months ended February 28, 2009, emphasizing stocks of corporations with strong balance sheets and with relatively low exposure to the deteriorating credit markets. The Fund maintained a portfolio of stocks in about 50 different companies. The stocks are always selected with the help of qualitative research analysis and quantitative analytical tools. Q What were some of the individual investments that most affected the Fund's results relative to the Russell 1000 Value Index during the six months ended February 28, 2009? A The financials sector was the poorest performing part of the market, as the stock valuations of many prominent institutions plummeted mainly because of their exposures to credit problems. Our decisions not to own shares of many of the major financial corporations were a substantial factor contributing to the Fund's outperformance relative to the Russell Index. The Fund's lack of exposure to Bank of America, for example, was the single biggest factor supporting its relative performance, while not owning any shares of Citigroup, Wells Fargo or American International Group also helped the Fund outperform the Russell Index. Similarly, the Fund's lack of any investment in General Electric (GE) helped its relative performance in the industrials sector. We avoided GE because we were concerned about the vulnerability of its financial services businesses, which have accounted for approximately 50% of its profits. Conversely, the Fund benefited from its investments in diversified capital goods companies United Technologies and 3M. In the consumer discretionary sector, the leading contributor was fast-food chain McDonald's. The company reported consistent growth in same-store sales in markets throughout the world, which may have been helped by the tendency of consumers to search for lower cost meals during a time of economic insecurity. Among other holdings, we sold the Fund's investment in global mining corporation Freeport McMoRan Copper & Gold at the right time. The Fund had a position in the corporation early in the reporting period, when it still was performing well, but we then sold it out of the portfolio and managed to avoid most of the damage to its stock price created by falling commodity prices. Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 5 Investments in the energy and health care sectors were not as successful for the Fund. In energy, Weatherford International produced particularly disappointing results. Weatherford, an oil field services company, was removed from the Standard & Poor's 500 Index, which led to share price losses as index funds sold their positions. In addition, investors became concerned about the outlook for oil field services companies due to falling oil prices. Conversely, the Fund had an underweighted position in ExxonMobil, which hurt relative performance as the integrated oil company was able to withstand the effects of falling oil prices better than most energy corporations. In health care, the Fund saw disappointing results from its holding in Cigna, an HMO, and Fund returns also were negatively impacted by not owning a stake in Wyeth. The share price of CIGNA was pulled down both by higher-than-expected operating costs and by investor concerns that the potential health care policies of the new Obama administration might affect profits of managed health care companies. Wyeth outperformed after agreeing to merge with Pfizer, and not owning the stock hurt the Fund's relative performance during the period. Q What is your investment outlook? A We intend to maintain a relatively defensive positioning for the Fund as we await an eventual improvement in the environment for equity investments. A cautious approach should be especially important for our stock selections in the energy and financials sectors, two large parts of the benchmark Russell Index that are particularly vulnerable to economic swings. In energy, we expect to be especially careful about investing in oil and natural gas exploration and production companies, particularly given that commodity prices have fallen and demand appears weak. In the financials group, we intend to emphasize corporations with strong balance sheets, while generally avoiding any companies with significant exposure to mortgages. We expect that individual stock-picking will continue to drive Fund performance. Please refer to the Schedule of Investments on pages 15-20 for a full listing of Fund securities. Investing in small and mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. 6 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 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 Research Value Fund Based on actual returns from September 1, 2008 through February 28, 2009. - -------------------------------------------------------------------------------- Actual Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 9/1/08 - -------------------------------------------------------------------------------- Ending Account Value $ 633.80 $ 631.50 $ 633.80 (after expenses) on 2/28/09 - -------------------------------------------------------------------------------- Expenses Paid $ 5.06 $ 7.73 $ 3.65 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 1.91%, and 0.90% for Class A, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the partial year period). Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 13 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.

Organization and Significant Accounting Policies Pioneer Disciplined Value Fund, formerly Pioneer Research Value Fund (the Fund), is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund was organized on October 12, 2005, and commenced operations on December 15, 2005. Pioneer Investment Management Inc. (PIM), the Fund's investment advisor, paid all organizational costs of the Fund. Prior to December 15, 2005, the Fund had no operations other than those relating to organizational matters and the initial capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund. The Fund's investment objective is to seek long-term capital growth. The Fund offers three classes of shares designated as Class A, Class C and Class Y shares. Class C shares were first publicly offered on July 17, 2008. Class Y shares were first publicly offered on July 31, 2008. Each class of shares represents and interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Share classes have exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. 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 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 27 larger, more established companies. The Fund's prospectuses contain unaudited information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the 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 prices and/or quotations are not readily available are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use fair value methods to value 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 February 28, 2009, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years are subject to examination by tax authorities. 28 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions paid will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended August 31, 2008 was as follows: ------------------------------------------------ 2008 ------------------------------------------------ Distributions paid from: Ordinary income $22,689 Long-term capital gain 21,742 ------------------------------------------------ Total $44,431 ================================================ The following shows the components of distributable earnings on a federal income tax basis at August 31, 2008: ---------------------------------------------------------- 2008 ---------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 4,697 Current year post October loss deferred (21,729) Unrealized appreciation 809 ---------------------------------------------------------- Total $ (16,223) ========================================================== The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned approximately $16 in underwriting commissions on the sale of Class A shares during the six months ended February 28, 2009. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 29 Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that Class A, Class C, and Class Y shares bear different transfer agent and distribution expense rates. E. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary cash investments. Credit Suisse, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund will be required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.75% of the Fund's average daily net assets up to $1 billion and 0.70% of the excess over $1 billion. For the six months ended February 28, 2009, the effective management fee (net of waivers and/or assumption of expenses) was equivalent to 0.75% of the Fund's average net assets. PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit the Fund's expenses to 1.25%, 2.15%, and 0.90% of the average daily net assets 30 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 attributable to Class A, Class C, and Class Y shares, respectively. These limitations are in effect through January 1, 2012 for Class A shares and January 1, 2010 for Class C shares and 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. There were no management fees, administrative costs or other services payable to PIM at February 28, 2009. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimbursed PIMSS for out-of-pocket expenses related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the six months ended February 28, 2009, out-of-pocket expenses by class of shares were as follows: - --------------------------------------------- Shareholder Communications - --------------------------------------------- Class A $120 - --------------------------------------------- Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $155 in transfer agent fees and shareholder communications expense payable to PIMSS at February 28, 2009. 4. Distribution Plan The Fund adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $14 in distribution fees payable to PFD at February 28, 2009. 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%, based on the lower of Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 31 cost or market value of shares being redeemed. There is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the six months ended February 28, 2009, no CDSCs were paid to PFD. 5. New Pronouncement In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. 32 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/09 Trustees, Officers and Service Providers Trustees Officers John F.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we 2 Pioneer Global Equity Fund | Semiannual Report | 2/28/09 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc. 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.

Pioneer Global Equity Fund | Semiannual Report | 2/28/09 3 Portfolio Management Discussion | 2/28/09 In the following interview, portfolio manager Piergaetano Iaccarino discusses the factors that influenced the Fund's performance for the semiannual period ended February 28, 2009. Q How did the Fund perform over the six-month period ended February 28, 2009? A The Fund slightly outperformed its benchmark, the Morgan Stanley Capital International (MSCI) World Index, during the six months, a period which saw a sharp deterioration in the environment for equities globally. For the six-month period ended February 28, 2009, the Fund's Class A shares posted a total return of -40.71% at net asset value, compared with a return of -43.38% for the MSCI World Index. Over the same six-month period, the average return of the 94 Global Large Cap Growth Funds tracked by Lipper, Inc. was -43.47%. Q Could you describe the environment in the global equity markets over the six-month period ended February 28, 2009? A Global equity markets dropped dramatically during the six-month period, with much of the damage occurring in the wake of the September 2008 turmoil in the credit markets. Across the globe, major financial institutions fell victim to a lack of liquidity due to a seizing up of credit markets. In the U.S., the failure of investment banking icon Lehman Brothers was the signature event. Lehman's failure was followed shortly by the U.S. government's bailout of global insurer AIG and the takeover of giant thrift Washington Mutual (by JP Morgan Chase). As September came to a close, venerable investment banks Morgan Stanley and Goldman Sachs converted to bank holding companies in order to assure ongoing liquidity support from the U.S. Federal Reserve Board (the Fed), as they sought shelter from the credit market storm. In Europe, governments were forced to pull together in October 2008 to rescue the continent's largest banks and prevent the global financial system from collapsing. Reflecting the severity of the damage to the global economy, the Fed implemented during the period a broad range of emergency facilities designed to add liquidity to the financial system. In addition, by December 2008, the Fed had lowered its target Federal funds rate (for short-term borrowing) from 2.00% to the unprecedented 0.00% to 0.25% range. Given the backdrop of an imperilled global financial system, equities in all regions experienced severe declines over the six months ended February 28, 2009. U.S. equities held up slightly better over the six months than did their 4 Pioneer Global Equity Fund | Semiannual Report | 2/28/09 European and Japanese counterparts. From a sector perspective, the strongest areas in the global equity markets were consumer staples and pharmaceuticals. Leading the way down was financials, followed by real estate, materials and capital goods. 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 the Fund holds will generally be overweighted by at least one percentage point compared with the MSCI World Index. In selecting securities for the Fund, we look for "growth at a reasonable price," and so there is a strong value component to our analysis. We try to find companies for the Fund that not only are benefiting from operating efficiencies as reflected in things like increased market share and revenues, but companies that also use their capital efficiently. In particular, we look for strong free cash flow, because this gives companies the flexibility to do things like make share buybacks, reinvest in their businesses, 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 we favor those stocks with the highest upside relative to their downside. In the extraordinary investment environment seen in recent months, characterized by a global financial crisis, this analysis has led us to invest the Fund in stocks within more defensive sectors. Q What holdings helped and hurt the Fund's performance over the six-month period ended February 28, 2009? A In the current environment, most prevailing theories of individual stock selection have been rendered ineffective by the narrow market preference for defensive sectors and companies positioned to weather the harshest economic and financing conditions. So it is no surprise that the Fund's outperformance versus the MSCI World Index over the six months was driven primarily by its sector allocations. In this vein, the Fund was underweight in financials, the sector which experienced the steepest declines during the period. The Fund was overweight in the relatively defensive pharmaceutical sector and also benefited from good stock selection within the sector. In particular, Bristol-Myers Squibb and Schering Plough held up much better than the rest of the market. The Fund had significant exposure to consumer staples stocks, which generally fell less than the overall market during the six months ended February 28, 2009. Within consumer staples, the Fund was overweight in low-cost retailer Wal-Mart Stores, which outperformed by a wide margin. Finally, stock selection within the materials sector added to Pioneer Global Equity Fund | Semiannual Report | 2/28/09 5 the Fund's benchmark-relative performance, including overweight exposures to materials manufacturer 3M and gold producers Newmont Mining and Goldcorp. On the negative side of the ledger, stock selection within energy detracted from the Fund's performance over the six months ended February 28, 2009, specifically, not owning diversified energy company ExxonMobil and overweighting oil producer El Paso. While underweighting the insurance group as a whole helped the Fund's returns, its exposure to Swiss Reinsurance was a leading negative contributor to performance, as the firm's stock experienced a severe decline related to its subprime mortgage exposure. Within telecommunications, our decision to favor Sprint over AT&T held back the Fund's performance, as Sprint fell substantially more than the rest of the sector. Finally, the Fund's overweight to French bank Societe Generale was a particularly strong performance detractor. Q What is your outlook and how is it reflected in the Fund's positioning? A At the end of February 2009, confirmation of the severity of the decline in economic conditions was delivered with the news that the U.S. economy (as measured by Gross Domestic Product) had contracted at an annual rate of more than 6% in the fourth quarter of 2008. We do not believe the global economy is likely to grow its way out of the financial crisis that originated in the subprime mortgage area anytime soon. Accordingly, we have positioned the Fund to potentially benefit from a deflationary environment. This means emphasizing companies that meet our criteria within more defensive sectors, such as consumer staples and pharmaceuticals, while downplaying exposure to firms within energy and materials. We also have been underweighting industrial companies that are heavily reliant on large-scale capital expenditures, while monitoring the impact of recent monetary initiatives designed to increase the availability of capital. On the positive side, the Federal and European central banks have shown that they will go to almost any length necessary to add liquidity to the financial system. In addition, we feel the significant drop in the price of crude oil that occurred over the second half of 2008 has the potential to help improve conditions for the major economies. Going forward, we believe our focus on companies with a strong cash position may hold the Fund in good stead as investors seek to weather the current economic storm. 6 Pioneer Global Equity Fund | Semiannual Report | 2/28/09 Please refer to the Schedule of Investments on pages 16-21 for a full listing of fund securities. Investing in foreign and/or emerging markets securities involves certain risks, including risks relating to interest rates, currency exchange rates, economic, and political conditions. Investments in mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund is non-diversified and invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of funds holding more securities. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

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.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Performance shown for periods prior to the inception of the Fund's Class Y shares on September 20, 2001 reflects the NAV performance of the Fund's Class A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares are generally higher than those of Class Y shares, the performance for Y shares prior to their inception would have been higher. Class A shares are used as a proxy through 9/20/01. Class Y shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. 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.

Pioneer Global Equity Fund | Semiannual Report | 2/28/09 13 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 and redemption fees. 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 Equity Fund Based on actual returns from September 1, 2008 through February 28, 2009. - ------------------------------------------------------------------------------------- Share Class A B C Y - ------------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 9/1/08** - ------------------------------------------------------------------------------------- Ending Account $ 592.90 $ 590.00 $ 590.30 $ 831.70 Value on 2/28/09 - ------------------------------------------------------------------------------------- Expenses Paid $ 5.09 $ 8.67 $ 8.64 $ 1.19 During Period* - ------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.29%, 2.20%, 2.19%, and 0.79 for Class A, Class B, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (60/365 for Class Y) (to reflect the partial year period). ** 12/31/08 for Class Y shares. 14 Pioneer Global Equity Fund | Semiannual Report | 2/28/09 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) or redemption fees that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Global Equity Fund Based on a hypothetical 5% return before expenses, reflecting the period from September 1, 2008 through February 28, 2009. - ------------------------------------------------------------------------------------- Share Class A B C Y - ------------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 9/01/08** - ------------------------------------------------------------------------------------- Ending Account $ 1,018.40 $ 1,013.88 $ 1,013.93 $ 1,006.92 Value on 2/28/09 - ------------------------------------------------------------------------------------- Expenses Paid $ 6.46 $ 10.99 $ 10.94 $ 1.30 During Period* - ------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.29%, 2.20%, 2.19%, and 0.79 for Class A, Class B, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (60/365 for Class Y) (to reflect the partial year period). ** 12/31/08 for Class Y shares.

Organization and Significant Accounting Policies Pioneer Global Equity Fund, formerly Pioneer Global Select Equity Fund, (the Fund), is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory business trust registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund is non-diversified. The Fund was organized on October 12, 2005, and commenced operations on December 15, 2005. The Fund's investment objective is to seek long-term capital growth. The Fund offers four classes of shares designated as Class A, Class B, Class C and Class Y shares. Class Y shares were first publicly offered on December 31, 2008. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each class of shares can bear different transfer agent and distribution fees. Share classes have exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting periods. Actual results could differ from those estimates. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those 30 Pioneer Global Equity Fund | Semiannual Report | 2/28/09 industries and sectors. The Fund's prospectuses contain unaudited information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued 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 using fair value methods pursuant to procedures adopted by the Board of Trustees ("management appraised"). The Fund invests primarily in securities of non-U.S. issuers. The principal exchanges and markets for such securities have closing times prior to the close of the NYSE. However, the value of these securities may be influenced by changes in global markets occurring after the closing times of the local exchanges and markets up to the time the Fund determines its net asset value. Consequently, the Board of Trustees of the Fund has determined that the use of daily fair valuations as provided by a pricing service is appropriate for the Fund. The Fund may also take into consideration other significant events in determining the fair value of these securities. Thus, the Fund's securities valuations may differ from prices reported by the various local exchanges and markets. At February 28, 2009 there were no securities that were management appraised. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. Pioneer Global Equity Fund | Semiannual Report | 2/28/09 31 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. Tax years for the prior three fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended August 31, 2008 was as follows: -------------------------------------------- 2008 -------------------------------------------- Distributions paid from: Ordinary income $ 127,503 Long-term capital gain 201,886 -------------------------------------------- Total $ 329,389 ============================================ C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $370 in underwriting commissions on the sale of Class A shares during the six months ended February 28, 2009. 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. 32 Pioneer Global Equity Fund | Semiannual Report | 2/28/09 E. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date as a hedge or cross-hedge against either specific investment transactions (settlement hedges) or portfolio positions (portfolio hedges). All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (See Note 6). F. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that Class A, Class B, Class C and Class Y shares can bear different transfer agent and distribution expense rates. G. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary cash investments. Credit Suisse, New York Branch, as the Fund's security lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive interest or payments in lieu of dividends on Pioneer Global Equity Fund | Semiannual Report | 2/28/09 33 the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund will be required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.75% of the Fund's average daily net assets up to $500 million; 0.70% of the next $500 million and 0.65% of the excess over $1 billion. For the six months ended February 28, 2009, the effective management fee (net of waivers and/or assumption of expense) was equivalent to 0.75% of the Fund's average net assets. PIM has contractually agreed to limit ordinary operating expenses of the Fund to the extent required to reduce the Fund's expenses to 1.30%, 2.20%, 2.20%, and 0.80% of the average daily net assets attributable to Class A, Class B, Class C and Class Y shares, respectively. These expense limitations are in effect through January 1, 2012 for Class A, and through January 1, 2010 for Class B, Class C and Class Y shares.

Expense Offsets Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended February 28, 2009, the Fund's expenses were reduced by $79 under such arrangements. 6. Forward Foreign Currency Contracts At February 28, 2009, the Fund had entered into various contracts that obligate the Fund to deliver currencies at specified future dates. At the maturity of a contract, the Fund must make delivery of the foreign currency. Alternatively, prior to the settlement date of a portfolio hedge, the Fund may close out such contracts by entering into an offsetting hedge contract. At February 28, 2009, Pioneer Global Equity Fund | Semiannual Report | 2/28/09 35 the Fund had no outstanding portfolio hedges.

New Pronouncement In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we 2 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 3 Portfolio Management Discussion | 2/28/09 In the following interview, portfolio manager Timothy Pynchon discusses the factors that affected the municipal bond market and the Pioneer High Income Municipal Fund over the six-month period ended February 28, 2009. Q How did the Fund perform during the six-month period ended February 28, 2009? A For the six-month period ended February 28, 2009, Pioneer High Income Municipal Fund's Class A shares produced a total return of -25.57% at net asset value. Over the same six-month period, the Fund's benchmark, the Barclays Capital (formerly Lehman Brothers) High Yield Municipal Bond Index returned -18.99%, while the average return of the 110 funds in the Lipper High Yield Municipal Debt Funds category was -17.69%. At a time when there was great disruption in the municipal bond market, investors were rewarded with a relatively high level of dividend income. As of February 28, 2009, the Fund's Class A shares generated a 30-day SEC yield of 9.09%; and the Fund's current yield (at NAV) was 8.89%, which translates into a taxable equivalent yield of 13.68%, based on the maximum Federal income tax rate of 35%. Q What was the investment environment like during the six-month period ended February 28, 2009? A There was great unrest in the financial markets, especially during the first four months of the period (September through December 2008), as problems in some of the biggest financial institutions led to unprecedented intervention by the U.S. Federal Reserve Board (the Fed) and a multibillion dollar U.S. government rescue package. Likewise, there was virtually no shelter in the high-yield municipal market from the downward price pressure, and the Fund suffered as a result. In this environment, the municipal bond market saw liquidity dry up, new issuance come to a halt, forced selling by several financial institutions, and a huge number of redemptions, as investors fled to the safety of the U.S. Treasury market. As a result of the turmoil, municipal bond yields rose to historic levels versus Treasury yields. Rarely in history has the ratio of municipal bond yields to Treasury yields been so high. The typical rate of municipal yields to Treasury yields has been about 90%. In December of 2008, the ratio increased to over 200%. In January and February of 2009, the municipal bond market rebounded. Liquidity improved slightly, and municipal bond prices rose, although their yields remained higher than Treasury yields. 4 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 Q How did you manage the Fund in this environment? A Like much of the market, the Fund felt the adverse effects of the market conditions stated above. We made no material changes to the Fund's portfolio, and we maintained our focus on high-yield municipal securities in areas that underpin the U.S. economy. The Fund's biggest weightings remain in those sectors essential to the U.S. economy. For example, as of February 28, 2009, investments in health care, which includes hospitals and life-care facilities, accounted for almost 36% of net assets; education was at more than 14% of net assets; prisons were at more than 12% of net assets; and public power also was at about 12% of net assets. Only about 20% of the Fund's investments were subject to the Federal Alternative Minimum Tax (AMT). At the end of the period on February 28, 2009, the Fund had 53 issues in 27 states. The average credit quality of the Fund's portfolio was BB+. Q What factors most affected the Fund's performance during the six-month period ended February 28, 2009? A The generally poor performance of the financial markets had a negative impact on virtually every type of bond over the past six months and, therefore, on the Fund's performance. The Fund was particularly affected by the poor performance of the tobacco settlement bonds and continuing-care retirement communities. Although both sectors are normally stalwart performers, the economic climate caused tobacco bonds to fall from favor and the marketing of life-care facilities to flatten. We continue to believe that good value remains in these credits, but the price performance has been overstated to the downside in the short term. Additionally, some investments defaulted, but they accounted for less than 3% of the Fund's holdings. We avoided virtually all housing bonds and real-estate development bonds (also known as "dirt" bonds), which were particularly hard hit in the wake of the subprime mortgage crisis. While the Fund had a setback over the past six months, its portfolio comprised what we believe are solid investments that could weather the current storm in the economy and the financial markets. As has always been the case at Pioneer, our investment decisions were based on a value-oriented, risk-managed investment approach that uses independent research, a bottom-up security selection process and top-down economic and market analysis. We are taking steps to further diversify the Fund's portfolio and to invest a portion of its assets in more liquid credits. Q What is your outlook? A As we look ahead, we believe that the second half of 2009 could be more positive for municipal bonds, as the credit markets continue to thaw and investors come back to the market. Over the past several months, the Fed Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 5 and the U.S. government have taken several steps to help remedy the problems in the banking industry and in credit markets, and to stimulate economic growth. States and municipalities are slated to receive a substantial portion of the government's economic stimulus package funding, which can be used for infrastructure repair, and medical and education programs. The infusion of money should be helpful to the municipal market, and we believe the Fund is well-positioned to benefit from a rebound in the high-yield municipal market when it eventually comes. Additionally, one of the long-term costs of increased government spending and new government programs may be higher taxes down the road. With that in mind, we believe the Pioneer High Income Municipal Fund may be a suitable investment option for appropriate long-term investors seeking relatively high income free from Federal taxes. Please refer to the Schedule of Investments on pages 14-19 for a full listing of Fund securities. Investments in high-yield or lower-rated securities are subject to greater-than-average risk. The Fund may invest in securities of issuers that are in default or that are in bankruptcy. A portion of the income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. The fund is not diversified, which means that it can invest a higher percentage of its assets in any one issuer than a diversified fund. Being non-diversified may magnify the Fund's losses from adverse events affecting a particular issuer. By investing primarily in municipal securities, the portfolio is more susceptible to adverse economic, political or regulatory developments than is a portfolio that invests more broadly. 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. Past performance is not a guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. 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. These opinions should not be relied upon for any other purposes. 6 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 Portfolio Summary | 2/28/09 Portfolio Quality - -------------------------------------------------------------------------------- (As a percentage of total investment portfolio) [THE DATA BELOW WAS REPRESENTED AS A PIE CHART IN THE PRINTED MATERIAL.] AA 2.2% BBB 9.4% BB & LOWER 88.4% Maturity Distribution - -------------------------------------------------------------------------------- (As a percentage of total investment portfolio) [THE DATA BELOW WAS REPRESENTED AS A PIE CHART IN THE PRINTED MATERIAL.] 1-3 Years 1.5% 3-6 Years 9.0% 6-8 Years 19.9% 8-10 Years 57.2% 10+ Years 12.4% 10 Largest Holdings - -------------------------------------------------------------------------------- (As a percentage of debt holdings)* 1.

Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 11 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables - -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: 1. Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 2.

The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer High Income Municipal Fund (the Fund) is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund is non-diversified. The Fund commenced operations on October 17, 2006. The investment objective of the Fund is to maximize total return through a combination of income that is exempt from regular federal income tax and capital appreciation. The Fund offers three classes of shares designated as Class A, Class C and Class Y shares. 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 identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each class of shares can bear different transfer agent and distribution fees. Share classes have exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses, and gain or loss on investments during the reporting period. Actual results could differ from those estimates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The fund's prospectuses contain unaudited information Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 27 regarding the fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements which, are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which market quotations are not readily available are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. At February 28, 2009, there were no securities that were valued using fair value methods. 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. Tax returns for the prior two fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. 28 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended August 31, 2008 was as follows: 2008 Distributions paid from: Tax-exempt income $2,433,183 Ordinary income -- - ----------------------------------------------- Total $2,433,183 =============================================== C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A., (UniCredit), earned $7,601 in underwriting commissions on the sale of Class A shares during the six months ended February 28th, 2009. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). 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 and at the same time, except that Class A, Class C, and Class Y shares can bear different transfer agent and distribution expense rates. 2. Management Agreement Pioneer Investment Management, Inc., (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.50% of the Fund's average daily net assets up to $500 million; 0.475% of the next $500 million; and 0.45% of the excess over Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 29 $1 billion. For the six months ended February 28, 2009, the effective management fee (net of waivers and/or assumption of expenses) was equivalent to 0.25% of the Fund's average net assets. PIM has contractually agreed to limit ordinary operating expenses (excluding taxes, commissions, interest and extraordinary expenses) of the Fund to the extent required to reduce the Fund's 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, 2012 and the Class C limitation is in effect through January 1, 2010. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund. Included in "Due to Affiliates" reflected on the Statement of Assets and Liabilities is $1,275 in management fees, administrative costs and certain other fees payable to PIM at February 28, 2009. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimbursed PIMSS for out-of-pocket expenses related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the six months ended February 28, 2009, such out of pocket expenses by class of shares were as follows: Shareholder Communications Class A $4,477 Class C 2,748 Class Y 6 - ------------------------------------------ Total $7,231 - ------------------------------------------ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $3,953 in transfer agent fees and shareholder communications expense payable to PIMSS at February 28, 2009. 4. Distribution Plans The Fund adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares consists of a 30 Pioneer High Income Municipal Fund | Semiannual Report | 2/28/09 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. Prior to February 1, 2008, PFD was reimbursed under the Distribution Plan for distribution expenses in an amount of up to 0.25% of the average daily net assets attributable to Class A shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,240 in distribution fees payable to PFD at February 28, 2009. 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% based on the lower of cost or market value of shares being redeemed. Proceeds from the CDSCs are paid to PFD. For the six months ended February 28, 2009, no CDSCs were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended February 28, 2009, the Fund's expenses were reduced by $130 under such arrangements. 6. New Pronouncement In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we 2 Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 3 Portfolio Management Discussion | 2/28/09 The U.S. equity market experienced a sharp decline during the six months ended February 28, 2009. The reasons for the downturn have been well documented in the media, as the financial crisis spread beyond the banking system to affect the broader global economy, growth stalled and the outlook for corporate earnings darkened. Additionally, stock prices have been pressured at various times by institutional investors' forced selling, questions regarding the effectiveness of the U.S. government's response, and the impact of sharply falling commodity prices. In the following interview, Robert McVicker, Pioneer Oak Ridge All Cap Growth Fund's Lead Portfolio Manager, discusses these and other factors that influenced the Fund's performance during the semiannual period ended February 28, 2009. Q How did the Fund perform during the past half-year ended February 28, 2009? A As would be expected during such a difficult time for the market, the Class A shares of the Fund posted an absolute return of -38.69% during the six-month period ended February 28, 2009. While we understand that our investors are distressed by the extent of the Fund's losses, we believe it is important to point out that the Fund managed to outperform its benchmark, the Russell 3000 Growth Index (the Russell Index), which returned -40.43% over the same period. In addition, during the same six months ended February 28, 2009, the average return of the 538 Multi-Cap Growth Funds tracked by Lipper, Inc. was -41.56%. In managing the Fund, we strive to purchase excellent businesses at attractive valuations. In the wake of the market's decline, we have been finding what we believe to be a wealth of attractively valued companies with strong fundamentals and the potential to generate strong annual earnings growth over the next three to five years. We believe our focus on such companies was an important factor in the Fund's outperformance of the benchmark and Lipper average during the semiannual period ended February 28, 2009. Q Where did the Fund deliver its best performance during the six months ended February 28, 2009? A The Fund had the most success in health care, due largely to our decision to focus on biotechnology stocks over pharmaceuticals. While the latter group has been plagued by concerns about patent expirations and weak pipelines of new drugs, the biotech sector is home to a greater number of companies where neither issue is a concern. The result was outperformance for the Fund in biotech relative to both the health care sector of the benchmark and the broader U.S. market. In this environment, the Fund benefited from a 4 Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 weighting of about 8% in this sector as of the end of the period, well above the 3.5% weighting in the Russell Index. The Fund's leading performers in the health care area were Gilead Sciences and Genentech, which has been engaged in takeover discussions with Roche Pharmaceuticals. The Fund's performance in health care also was helped by a position in Thermo Fisher. The company, which has been gaining market share in the life sciences tools business, managed to generate organic sales growth of 4% during the extremely challenging fourth quarter of 2008. We believe the shares of the market-leading company are an outstanding value, with a price-to-earnings (P/E) ratio of about 10, which is below our expectations for a 12% earnings growth rate in the next three to five years. The energy sector also was a source of positive performance for the Fund during the six-month period ended February 28, 2009. While the Fund's holdings produced a negative absolute return -- consistent with the downturn in the broader sector -- holdings such as XTO Energy and Southwestern Energy outperformed their peers due to their strong production profiles. Even if energy prices remain at depressed levels, we believe both companies can continue to outperform their peers by exploiting attractive drilling prospects to drive their production growth. As part of our investment process, we look for companies that generate consistent, predictable earnings. This is true even in the industrials sector, where we have focused on investing the Fund in less economically sensitive companies with steadier, recurring revenue streams. The Fund's leading contributor in the industrials group was Stericycle, which manages the removal and disposal of hospitals' medical waste. As such, Stericycle offers a stable business model and steady revenue growth, both favorable attributes in the current environment. Q What were some areas in which the Fund underperformed during the six months ended February 28, 2009? A The Fund's underperformance was most significant in the technology sector. While we believe the technology companies held by the Fund remain attractive on a fundamental basis, this was not reflected in their recent market performance. For example, shares of both Google and Apple continued to fall sharply amid the weakness in the broader market. With respect to Google, we remain positive on the stock since it is now trading at a valuation in line with that of the broader market, even though it has a stronger-than-expected growth rate. Similarly, Apple has fallen to a 16 P/E, despite an expected growth rate in the low-to-mid teens and a history of offering breakthrough products. While the two stocks were depressed during the semiannual reporting period, we expect both can perform well over a full market cycle due to their attractive underlying fundamentals. Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 5 In the consumer staples sector, the Fund's relative performance was hurt both by what the Fund owned as well as what it did not own. Specifically, the Fund's position in Central European Distributors, an American company whose primary business is the distribution of spirits throughout Russia and Eastern Europe, fell sharply due to the declining value of the Russian ruble and Polish zloty. While the fundamentals of the company remain strong, the effect of currency exchange rates makes its performance inherently unpredictable. We therefore elected to eliminate the stock from the Fund's portfolio. Also weighing on performance during the period was the Fund's lack of a position in Wal-Mart Stores, which was one of the best performing stocks in the Russell Index, as cash-strapped consumers traded down to less expensive alternatives. In our annual report to shareholders dated August 31, 2008, we cited our focus on financial companies outside of the troubled banking sector as being a key positive factor in the Fund's performance. During the past six months, however, the positioning failed to add value, as falling stock prices weighed on the performance of the Fund's holdings in Charles Schwab and IntercontinentalExchange. Insurer Aflac also pressured the Fund's performance mainly due to its holdings in bonds issued by European banks. The potential for the nationalization of banks in Europe, along with the prospect of default on the bonds, has increased significantly. Not wanting to expose the Fund to the risk associated with that potential development, we elected to sell Aflac from the Fund's portfolio. Q Has the bear market provided opportunities to add some new stocks to the Fund's portfolio? A Yes, it has. In the past, we would typically consider a stock to be trading at a P/E-to-growth rate (or PEG) of under two to be a reasonable value. Today, we have been finding a wealth of stocks that are trading with PEGs of less than one. Notably, these are not lower-quality stocks, but the kind of stable growers in which we seek to invest the Fund's assets. Some examples of what we believe to be strong companies whose stocks we were able to purchase at good valuation levels include: International Business Machines (IBM), Kroger, ResMed and Quanta Services. IBM is a company that we expect to grow strongly over the next three to five years. We like IBM for its strong balance sheet and the recurring revenues it generates from its longer-term service contracts. Supermarket chain Kroger is another company whose stock price declined with the overall market, but in which we see the potential for solid earnings growth over a full economic cycle. Kroger is able to offer very competitive pricing to consumers as a result of its ongoing efforts to streamline its business, enabling it to take market share in a tough environment. ResMed, a maker of sleep apnea treatment products, also was added to the Fund as its stock price dipped with the 6 Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 overall market. We believe ResMed has very strong potential due to the increasing awareness of sleep apnea as a medical problem that afflicts millions of people, and the need for new and innovative treatments of the condition. Quanta Services is a utility services company that we expect will capitalize on the need to upgrade the U.S. power grid. We also expect that the company will benefit from the Obama administration's infrastructure investment program. We expect Quanta to generate reliable growth in the coming years. Q What is your outlook? A Like most money managers, we remain very cautious on the short-term outlook for the market. Still, we see reasons for longer-term optimism. The widespread and indiscriminate selling that has characterized the recent market downturns has created compelling values among high-quality companies, several of which were noted above. On the whole, we believe the companies we hold in the Fund will be able to hold up well through the downturn, and then may ultimately flourish as an improving economic environment eventually lifts the pressure currently weighing on the valuations of otherwise healthy companies. As we believe that long-term investors will likely look back on this period as a favorable time to invest, we view the ongoing market volatility as an opportunity to purchase proven franchises for the Fund at very attractive valuations.

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 All Cap Growth Fund Based on actual returns from September 1, 2008 through February 28, 2009. - -------------------------------------------------------------------------------- Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 9/1/08 - -------------------------------------------------------------------------------- Ending Account $ 613.10 $ 611.50 $ 614.20 Value on 2/28/09 - -------------------------------------------------------------------------------- Expenses Paid $ 5.00 $ 8.59 $ 3.80 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2,15%, and 0.95%, for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 13 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Oak Ridge All Cap Growth Fund (the Fund) is one of five portfolios comprising Pioneer Series Trust V, a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is capital appreciation. The Fund offers three classes of shares designated as 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 identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each class of shares can bear different transfer agent and distribution fees. Share classes have exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectuses contain unaudited information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 27 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 is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use fair value methods to value 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 February 28, 2009 there were no securities that were valued using fair value methods. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Dividend and interest income is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net 28 Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions payable will be determined at the end of the current taxable year. There were no distributions paid during the year ended August 31, 2008. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned approximately $1,069 in underwriting commissions on the sale of Class A shares during the six months ended February 28, 2009. D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on the respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time and on the same day, except that Class A, Class C, and Class Y shares bear different transfer agent and distribution expense rates. E. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary cash investments. Credit Suisse, New York Branch, as the Fund's security lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive interest or payments in lieu of dividends on Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 29 the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund will be required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. PIM receives a basic fee that is calculated at the annual rate of 0.75% of the Fund's average daily net assets up to $500 million; and 0.70% on assets over $500 million. The management fees were equivalent to 0.75% of the average daily net assets for the six months ended February 28, 2009. PIM has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.25% and 2.15% of the average daily net assets attributable to Class A and Class C shares, respectively. These expense limitations are in effect through January 1, 2012 for Class A shares and through January 1, 2010 for Class C shares. Effective January 1, 2009, PIM has contractually agreed to limit Class Y expenses to 0.95% of the average daily net assets attributable to Class Y shares. This expense limitation is in effect through January 1, 2010. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $3,572 in management fees, administrative costs, and certain other fees payable to PIM at February 28, 2009. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund paid out-of-pocket expenses incurred by PIMSS related to shareholder activities such as proxy and statement mailing, outgoing phone calls and omnibus relation contracts. For the six months ended February 28, 2009, out-of-pocket expenses were as follows: - ----------------------------------------------- Shareholder Communications - ----------------------------------------------- Class A $1,153 Class C 86 Class Y (118) - ----------------------------------------------- Total $1,121 =============================================== 30 Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,017 in transfer agent fees and shareholder communications expense payable to PIMSS at February 28, 2009. 4. Distribution Plans The Fund adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares 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. Prior to February 1, 2008, PFD was reimbursed under the Distribution Plan for distribution expenses in an amount of up to 0.25% of the average daily net assets attributable to Class A shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $108 in distribution fees payable to PFD at February 28, 2009. 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% based on the lower of cost or market value of shares being redeemed. Proceeds from the CDSCs are paid to PFD. For the six months ended February 28, 2009, no CDSCs were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into an expense offset arrangement with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended February 28, 2009, the Fund's expenses were reduced by $61 under such arrangements. 6. New Pronouncement In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 31 Approval of Sub-Advisory Agreement (unaudited) Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. PIM has retained Oak Ridge Investments, LLC to serve as the sub-adviser to the Fund pursuant to a sub-advisory agreement between PIM and the sub-adviser. At a meeting held on January 8, 2008, the Trustees of the Fund approved an amended and restated investment advisory agreement between the Fund and PIM. Shareholders of the Fund approved the amended and restated investment advisory agreement on May 13, 2008. The material factors and conclusions with respect thereto that formed the basis for the Trustees' approval of the amended and restated investment advisory agreement are included in the Fund's semi-annual report for the period ended June 30, 2008. At a meeting held on November 11, 2008, based on their evaluation of the information provided by PIM and the sub-adviser, the Trustees of the Fund, including the independent Trustees voting separately, unanimously approved the continuation of the sub-advisory agreement for the Fund for another year. In considering the continuation of the sub-advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the continuation of the sub- advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services provided to the Fund by the sub-adviser, taking into account the investment objective and strategy of the Fund and the information related to the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the sub-advisory agreement. The Trustees also reviewed the sub-adviser's investment approach for the Fund and its research process. The Trustees considered the resources of the sub-adviser and the personnel of the sub-adviser who provide investment management services to the Fund. Based on these considerations, the Trustees concluded that the nature, extent and quality of services provided by the sub-adviser to the Fund were satisfactory and consistent with the terms of the sub-advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by 32 Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees noted that the Fund commenced operations on October 16, 2006. The Trustees considered that the Fund's annualized total return was in the third quintile of its Morningstar category for the one year period ended June 30, 2008. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Sub-advisory Fee and Expenses The Trustees considered the fees payable to the sub-adviser under the sub- advisory agreement. They also considered that PIM, not the Fund, paid the sub-adviser out of the management fees paid to PIM under the investment advisory agreement. The Trustees considered information regarding the management fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2008 was in the third quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2008 was in the second quintile relative to its Strategic Insight peer group. The Trustees also reviewed the advisory fees charged by the sub-adviser to its other clients with similar investment strategies as the Fund. The Trustees noted that the fee rates for those clients generally were higher than the sub-advisory fees paid to the sub-adviser with respect to the Fund. The Trustees concluded that the sub-advisory fee payable by PIM to the sub- adviser of the Fund was reasonable in relation to the nature and quality of services provided by the sub-adviser. The Trustees also concluded that the Fund's expense ratio was reasonable. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. They also considered PIM's profit margin in connection with the overall operation of the Fund. The Trustees further considered the sub-advisory fees received by the sub-adviser with respect to the Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 33 Fund and the percentage that such fees represented of the sub-adviser's overall revenues (for the 12-month period ended December 31, 2007). They also reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered the profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that each of PIM and the sub-adviser should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that the profit margins with respect to the management of the Fund were not unreasonable. Economies of Scale The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. The Trustees concluded that, because of the breakpoints in the management and sub-advisory fee schedules and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared with the Fund. Other Benefits The Trustees considered the other benefits to the sub-adviser from its relationship with the Fund, including the benefits to the sub-adviser and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees further considered the intangible benefits to the sub-adviser by virtue of its relationship with the Fund and certain of the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between the sub-adviser and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the sub-advisory agreement for the Fund between PIM and the sub-adviser, including the fees payable thereunder, was fair and reasonable and voted to approve the continuation of the sub-advisory agreement for the Fund. 34 Pioneer Oak Ridge All Cap Growth Fund | Semiannual Report | 2/28/09 Trustees, Officers and Service Providers Trustees Officers John F.

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.

The Fund's audit committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the Affiliates (as defined) that were not pre- approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
