Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. Tax hikes, spending restraint and a better economy have meaningfully cut the federal budget deficit. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has hinted that rates may be raised sooner than anticipated, market expectations are still focused on no earlier than 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faces a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect market volatility. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world. We encourage you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at us.pioneerinvestments.com. We greatly appreciate your trust in us, and we 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 | 2/28/14 3 Portfolio Management Discussion | 2/28/14 Note to Shareholders: Effective June 7, 2013, Pioneer Disciplined Value Fund ("the predecessor fund") reorganized with Pioneer Fundamental Value Fund. As a result of the reorganization, Pioneer Fundamental Value Fund was renamed Pioneer Disciplined Value Fund. The investment strategies, performance and financial history, inception date, fiscal year end, and portfolio management team of the combined Fund are that of the predecessor Pioneer Disciplined Value Fund. In the following interview, John Peckham, CFA, Co-Head of Equity Research, U.S., at Pioneer, and Ashesh (Ace) Savla, senior quantitative research analyst at Pioneer, discusses the market environment for stocks during the six-month period ended February 28, 2014, and the performance of Pioneer Disciplined Value Fund in that environment. Mr. Peckham, along with Mr. Savla, and Brian Popiel, fundamental research analyst at Pioneer, are responsible for the day-to-day management of the Portfolio. Q How did the Fund perform during the six-month period ended February 28, 2014? A Pioneer Disciplined Value Fund's Class A shares returned 13.18% at net asset value during the six-month period ended February 28, 2014, while the Fund's benchmark, the Russell 1000 Value Index (the Russell Index), returned 13.46%. During the same six-month period, the average return of the 1,270 mutual funds in Morningstar's Large Value Funds category was 12.87%, and the average return of the 495 mutual funds in Lipper's Large Cap Value Funds category was 13.17%. Q How would you describe the investment environment in the equity market during the six-month period ended February 28, 2014? A We would characterize it as a "risk-on" environment, as the market shook off a lot of potential bad news during the period, including the difficult launch, to say the least, of the Affordable Care Act (ACA), the suggestion (and then implementation) by the Federal Reserve (Fed) of a tapering of its quantitative easing (QE) bond-buying program, and several geopolitical factors, most recently Russia's military incursion into Crimea. Despite those risks, the robust investment environment prevailed for most of the six-month period. There was a slight pullback in January, but that was followed by a good recovery in February, the final month of the period. Cyclical sectors, like industrials, materials, and consumer discretionary fared well in the "risk-on" environment, while the more defensive sectors, like consumer staples, lagged. One notable exception was health care, a defensive sector that posted very strong performance during the period, even in light of the well-publicized difficulties with the ACA launch. 4 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 Q Which of your investment decisions and/or stock picks contributed the most to the Fund's benchmark-relative performance during the six-month period ended February 28, 2014? A Our pro-cyclical bias in the portfolio worked out well and aided benchmark- relative returns. The Fund benefited from an overweight to industrials, which was the top-performing sector in the Russell Index, and from underweights to utilities and telecom services, which underperformed most cyclical sectors during the period. An underweight to energy, which was the worst-performing cyclical sector in the Russell Index during the six-month period, also contributed to the Fund's benchmark-relative returns. Stock selection in consumer staples, financials, industrials, and materials contributed the most to relative performance during the period. In consumer staples, the two Fund holdings that added the most to relative returns were Coca-Cola Enterprises and CVS/Caremark. Coca-Cola Enterprises has had good year-over-year results in Europe and has been realizing the positive effects of its share buybacks. CVS/Caremark's joint venture with Cardinal Health to distribute generic drugs has provided a nice boost to the stock's performance, and the company also has seen good performance from its drugstore component. In addition, not owning Procter & Gamble, a significant underperformer during the period, aided benchmark-relative returns in the consumer staples area. In industrials, airline stock United Continental proved to be the top-performing holding (relative to the Russell Index) in the entire portfolio during the six-month period. United Continental has proved to be a good turnaround story, and airline industry consolidation, overall, has been a positive. Also in industrials, the Fund's position in Ingersoll-Rand made a significant contribution to returns. Ingersoll-Rand has good exposure to the upticks in residential and non-residential construction, and the company also spun-off its security business, a move that was well received by the market. In materials, the Fund's position in LyondellBasell was the top contributor to returns from that sector. The company has reported good results driven in large part by low North American natural gas prices. In financials, a lot of inexpensive cyclical stocks outperformed during the period, and the Fund's holdings of Discover Financial, JPMorgan, and Morgan Stanley all contributed to relative returns. In addition, avoiding Berkshire-Hathaway, which underperformed, aided benchmark-relative returns in financials. Other top contributors to benchmark-relative returns were Fund positions in Yahoo! (information technology) and Cardinal Health (health care). Yahoo! owns about one-quarter of Chinese firm Alibaba, a group of Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 5 Internet-based e-commerce businesses, and Alibaba's growth helped to drive Yahoo's! performance during the period. We exited the Fund's position once the stock hit fair value. Cardinal Health's performance has benefited from its joint venture with CVS/Caremark, mentioned earlier. Q Which of your investment decisions and/or stock picks detracted the most from the Fund's benchmark-relative performance during the six-month period ended February 28, 2014? A Stock selection in energy was the biggest detractor from benchmark-relative returns during the period, while selection in consumer discretionary and information technology also held back results. In energy, exploration-and-production companies fared poorly during the period, and the Fund owned several such stocks, including Marathon Oil, Apache, and ConocoPhillips. In information technology, despite the Fund's success with the Yahoo! investment, mentioned earlier, those positive results were overshadowed by not holding some of the sector's top performers--Micron Technology, in particular. In consumer discretionary, the Fund's position in home improvement company Lowe's detracted from relative returns. We sold the stock before the end of the period. Sector allocation decisions did not have a huge negative impact on the Fund's relative returns, though the portfolio's overweight to the financials sector, which was one of the bottom five performers in the Russell Index during the period, was a modest detractor. Q What is your outlook for the equity market and how have you positioned the Fund's portfolio heading into the second half of the Fund's fiscal year? A Given the Fed's tapering of QE and the general improvement in the domestic economy over the past year, we are very much aware that interest rates may begin to rise even sooner than expected, so we have positioned the Fund's portfolio in anticipation of higher interest rates. We still have a cyclical bias in the portfolio, but have slightly reduced the Fund's allocation to consumer discretionary, as it is getting harder to find cheap stocks in the sector. We have increased the Fund's holdings in materials while remaining underweight to energy. In industrials, the Fund has a sizable allocation to the airline industry. In the defensive sectors, health care seems to be the place to be right now, so we have maintained the Fund's overweight to the sector. 6 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 At the present time, equities still appear to be good investments, especially compared with fixed-income alternatives. Given the sharp rally in stocks since the beginning of 2013, some have questioned if the market is overvalued, but we are still finding many cheap stocks in key sectors such as financials and materials. In fact, over the past six months, portfolio turnover mainly involved the sales of stock positions that had appreciated, then replacing them with cheaper names. To date, we have not had a problem finding those cheaper alternatives, so the value in the market still appears to be there. Please refer to the Schedule of Investments on pages 18-22 for a full listing of Fund securities. 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. Investments 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. 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. These risks may increase share price volatility.

All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The net expense ratio reflects the contractual expense limitation currently in effect through January 1, 2015, for Class R shares. There can be no assurance that Pioneer will extend the expense limitation beyond such time. Please see the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. The Fund acquired the assets and liabilities of Pioneer Disciplined Value Fund ("the predecessor fund") on June 7, 2013. As a result of the reorganization, the predecessor fund's performance and financial history became the performance and financial history of the Fund. The performance of Class Y shares of the Fund is the performance of Class Y shares of the predecessor fund for periods prior to the reorganization, and has not been restated to reflect any differences in expenses. Performance shown for periods prior to the inception of Class Y shares of the predecessor fund on July 31, 2008, is the net asset value performance of the predecessor fund's Class A shares, which has not been restated to reflect any differences in expenses, including Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares generally are higher than those of Class Y shares, the performance of Class Y shares of the predecessor fund prior to their inception on July 31, 2008, would have been higher than the performance shown. 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.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. The Fund acquired the assets and liabilities of Pioneer Disciplined Value Fund ("the predecessor fund") on June 7, 2013. As a result of the reorganization, the predecessor fund's performance and financial history became the performance and financial history of the Fund. The predecessor fund did not offer Class Z shares. Accordingly, the performance of Class Z shares of the Fund is the performance of Class A shares of the predecessor fund for periods prior to the reorganization, and has not been restated to reflect any differences in expenses. Class Z 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.

Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 15 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Disciplined Value Fund Based on actual returns from September 1, 2013, through February 28, 2014. ---------------------------------------------------------------------------------------- Share Class A B C R Y Z ---------------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 9/1/13 ---------------------------------------------------------------------------------------- Ending Account $1,131.80 $1,127.00 $1,127.80 $1,130.60 $1,133.60 $1,133.00 Value (after expenses) on 2/28/14 ---------------------------------------------------------------------------------------- Expenses Paid $ 6.34 $ 10.76 $ 10.08 $ 7.40 $ 4.29 $ 4.76 During Period* ---------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.20%, 2.04%, 1.91%, 1.40%, 0.81%, and 0.90% for Class A, Class B, Class C, Class R, Class Y, and Class Z shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 16 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 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 Disciplined Value Fund (the Fund) is a series of Pioneer Series Trust III, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund acquired the assets and liabilities of Pioneer Disciplined Value Fund (the "predecessor fund"), a series of Pioneer Series Trust V, on June 7, 2013. The predecessor fund was the accounting survivor of the reorganization. Accordingly, the predecessor fund's performance and financial history became the performance and financial history of the Fund. The financial highlights and shareholder activity, as reflected in the statement of changes in net assets, have been adjusted to reflect the conversion rations used for the reorganization of the Fund with the predecessor fund. Prior to the reorganization, the Fund was named Pioneer Fundamental Value Fund. The Fund's investment objective is to seek long-term capital growth. The Fund offers six classes of shares designated as Class A, Class B, Class C, Class R, Class Y and Class Z shares. The predecessor fund did not offer Class B, Class R or Class Z shares. Accordingly, financial reporting for Class B, Class R and Class Z shares commenced on June 7, 2013 and no financial information has been presented for prior periods. 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 rates of 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 from net investment income earned 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 share class has 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 or Class Z 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 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 33 and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities that have traded on an exchange 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 available, generally are valued at the mean between the last bid and asked prices. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Shares of money market mutual funds are valued at such funds' net asset value. 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. Securities for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, pursuant to procedures adopted by the Fund's Board of Trustees. PIM's fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Trustees. PIM's fair valuation team is responsible for monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee of the Board of Trustees. At February 28, 2014, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). 34 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 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 is recorded on the accrual basis. Dividend and interest income are reported 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 provision for federal income taxes is required. As of February 28, 2014, the Fund did not accrue any interest or penalties related to uncertain tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three fiscal years remain subject to examination by Federal and State tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions during the year ended August 31, 2013 were as follows: -------------------------------------------------------------------------------- 2013 -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 933,319 Long-term capital gain 2,097,827 -------------------------------------------------------------------------------- Total $3,031,146 ================================================================================ Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 35 The following shows the components of distributable earnings on a federal income tax-basis at August 31, 2013: -------------------------------------------------------------------------------- 2013 -------------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 2,095,497 Undistributed long-term capital gain 129,600,550 Capital loss carryforward (11,294,142) Net unrealized appreciation 148,932,441 -------------------------------------------------------------------------------- Total $269,334,346 ================================================================================ Due to a different tax survivor and different tax year ends, the tax amounts include those related to Fund's tax year ended June 30, 2013 as well as its short tax year ended August 31, 2013. The difference between book-basis and tax-basis net unrealized appreciation is attributable to the tax deferral of losses on wash sales and tax basis adjustments on other holdings. 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 $17,292 in underwriting commissions on the sale of Class A shares during the six months ended February 28, 2014. 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 its 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, Class C and Class R shares of the Fund, respectively (see Note 4). Class Y and Class Z shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares 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 net investment income dividends to Class A, Class B, Class C, Class R, Class Y and Class Z shares can reflect different transfer agent and distribution expense rates. 36 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 E. Risks At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. 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 equal to 0.65% of the Fund's average daily net assets up to $1 billion, 0.60% of the next $2 billion of the Fund's average daily net assets, 0.55% of the next $4.5 billion of the Fund's average daily net assets and 0.525% of the Fund's average daily net assets over $7.5 billion. Prior to June 7, 2013, the Fund paid an annual fee equal to 0.70% of the Fund's average daily net assets up to $1 billion, 0.65% of the next $1 billion of the Fund's average daily net assets, 0.60% of the next $1 billion of the Fund's average daily net assets, 0.55% of the next $4.5 billion of the Fund's average daily net assets, and 0.525% of the Fund's average daily net assets over $7.5 billion. Prior to June 7, 2013, the predecessor fund paid a management fee equal to 0.65% of the predecessor fund's average daily net assets up to $1 billion, 0.60% of the next $4 billion of the predecessor fund's average daily net assets and 0.55% of the predecessor fund's average daily net assets over $5 billion. For the six months ended February 28, 2014, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.64% of the Fund's average daily net assets. PIM has contractually agreed to limit ordinary operating expenses of the Fund to the extent required to reduce Fund expenses to 1.20%, 2.10%, 2.10%, 1.40%, 0.85% and 0.90% of the average daily net assets attributable to Class A, Class B, Class C, Class R, Class Y and Class Z shares, respectively. Fees waived and expenses reimbursed during the six months ended February 28, 2014 are reflected on the Statement of Operations. These expense limitations are in effect through January 1, 2015. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the date referred to above. 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 as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $54,364 in management fees, administrative costs and certain other reimbursements payable to PIM at February 28, 2014. Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 37 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 reimburses PIMSS for out-of-pocket expenses incurred by PIMSS 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, 2014, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications -------------------------------------------------------------------------------- Class A $ 628,592 Class B 29,934 Class C 185,453 Class R 43,187 Class Y 147,715 Class Z 13,141 -------------------------------------------------------------------------------- Total $1,048,022 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $492,599 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at February 28, 2014. 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class B, Class C and Class R 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 also pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee for Class B and 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. Pursuant to the Plan, the Fund further pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $36,979 in distribution fees payable to PFD at February 28, 2014. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan administrators or other service organizations that agree to provide certain 38 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 services to retirement plans or plan participants holding shares of the Fund a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Class R Class Y and Class Z 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 12 months of purchase. Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within 12 months of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class R, Class Y or Class Z shares. Proceeds from the CDSCs are paid to PFD. For the six months ended February 28, 2014, CDSCs in the amount of $10,118 were paid to PFD. 5. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. The credit facility in effect until February 12, 2014 was in the amount of $215 million. As of February 12, 2014, the facility is in the amount of $240 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (LIBOR) plus 0.90% (0.85% as of February 12, 2014) on an annualized basis, or the alternate base rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the federal funds rate on the borrowing date and (c) 2% plus the overnight eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in the credit facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the six months ended February 28, 2014, the Fund had no borrowings under the credit facility. 6. Reorganization Information On June 7, 2013 ("Closing Date"), the Predecessor Fund was reorganized with the Fund. The purpose of this transaction was to combine two funds (managed by PIM) with similar investment objectives and strategies. This tax-free reorganization was accomplished by exchanging the assets and liabilities of the Predecessor Fund for shares of the Fund. Shareowners holding Class A, C and Y shares of the Predecessor Fund received Class A, C and Y shares Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 39 of the Fund, respectively, in the reorganization. The Predecessor Fund did not offer Class B, Class R or Class Z shares. Financial reporting for Class B, Class R and Class Z shares commenced on June 7, 2013. The investment portfolio of the Predecessor Fund, with an aggregate value of $50,070,555 and an identified cost of $40,253,651 at June 7, 2013, was the principal asset acquired by the Fund. For financial reporting purposes, assets received and shares issued by the Fund were recorded at net asset value, however, the cost basis of the investments received from the Predecessor Fund was carried forward to align ongoing reporting of the Fund's realized and unrealized gains and losses with amounts distributable to shareowners for tax reporting purposes. The Fund was the legal survivor of the reorganization. The Predecessor Fund was the accounting survivor of the reorganization. Accordingly, the Predecessor Fund's performance and financial history became the performance and financial history of the Fund. Prior to the reorganization, the Fund was named Pioneer Fundamental Value Fund. The following charts show the details of the reorganization as of the Closing Date: ------------------------------------------------------------------------------------------- Pioneer Fundamental Pioneer Disciplined Pioneer Disciplined Value Fund Value Fund Value Fund (Pre-Reorganization) (Pre-Reorganization) (Pre-Reorganization) ------------------------------------------------------------------------------------------- Net Assets Class A $ 764,864,326 $ 3,770,407 $ 768,634,733 Class B 34,055,436 -- 34,055,436 Class C 227,553,144 1,114,387 228,667,531 Class R 25,400,093 -- 25,400,093 Class Y 399,112,240 45,499,772 444,612,012 Class Z 7,193,120 -- 7,193,120 ------------------------------------------------------------------------------------------- Total Net Assets $ 1,458,178,359 $50,384,566 $ 1,508,562,925 ------------------------------------------------------------------------------------------- Shares Outstanding Class A 37,992,998 187,303* 38,180,301 Class B 1,695,126 -- 1,695,126 Class C 11,375,131 55,719* 11,430,850 Class R 1,281,684 -- 1,281,684 Class Y 19,796,357 2,256,944* 22,053,301 Class Z 359,707 -- 359,707 40 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 ------------------------------------------------------------------------------------------- Pre-conversion Conversion Post-conversion Shares Ratio* Shares ------------------------------------------------------------------------------------------- Class A 390,457 0.4797 187,303 Class C 114,961 0.4847 55,719 Class Y 4,641,814 0.4862 2,256,944 * Shares amount have been adjusted to reflect conversion ratios utilized to align the net asset values of the Predecessor Fund with those of the Fund. ------------------------------------------------------------------------------------------- Shares Exchange Issued In Ratio Reorganization** ------------------------------------------------------------------------------------------- Class A 1.0000 37,992,998 Class B 1.0000 1,695,126 Class C 1.0000 11,375,131 Class R 1.0000 1,281,684 Class Y 1.0000 19,796,357 Class Z 1.0000 359,707 ** Reflects shares issued by the predecessor fund, the accounting survivor as shown on the Statement of Changes. ------------------------------------------------------------------------------------------- Unrealized Accumulated Appreciation Gain (loss) on Closing Date on Closing Date ------------------------------------------------------------------------------------------- Fund $275,137,514 $6,693,976 Predecessor Fund 9,816,904 5,073 Assuming the Reorganization had been completed on September 1, 2012, the beginning of the Fund's current fiscal period, the pro forma results of operations for the fiscal year ended August 31, 2013, are as follows: Net Investment income (loss) $ 36,192,855 Net realized and unrealized gains (losses) 693,749,029 ------------------------------------------------------------------------------------------- Change in net assets resulting from operations $729,941,884 =========================================================================================== Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it is not practical to separate the amounts of revenue and earnings of the Fund that have been included in the Statements of Operations since the Reorganization was consummated. Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 41 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Disciplined Value Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in March 2013 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2013, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement. The contract review materials were provided to the Trustees in July 2013 and September 2013. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the Independent Trustees of the Fund were held in July, September, and November, 2013 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at regularly scheduled meetings. At a meeting held on November 12, 2013, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. 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 did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in 42 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees review the Fund's performance on a regular basis, based on analysis and data prepared by PIM for this purpose and discuss performance issues with PIM on an ongoing basis. For purposes of their contract renewal deliberations, the Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the fourth quintile of its Morningstar category for the one, three and five year periods ended June 30, 2013. The Trustees noted the discussions held throughout the year regarding the Fund's performance and confirmed that those discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. The Trustees considered reasons for the underperformance of the Fund relative to its peer group and the steps recently taken in an effort to improve the performance of the Fund. The Trustees agreed that they would continue to closely monitor the Fund's performance. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to 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. Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 43 The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2013 was in the second quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees considered that the Fund's expense ratio for the twelve months ended June 30, 2013 was in the fifth quintile relative to its Strategic Insight peer group for the comparable period, and in the third quintile relative to its Morningstar category for the comparable period. The Trustees noted that PIM was waiving fees and/or reimbursing expenses in order to limit the ordinary operating expenses of the Fund. The Trustees reviewed management fees charged by PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer") to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from 44 Pioneer Disciplined Value Fund | Semiannual Report | 2/28/14 non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to identify and quantify, rarely identifiable on a fund-by-fund basis, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Fund. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. The Trustees considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.

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.
