Mid-sized and small-cap indices scored modest gains, while indicators that track large-cap stocks showed even smaller changes. For bond investors, Treasury issues wound up the period with higher yields and lower prices than at year-end. The same was true of corporate issues, whose prices gave ground in the face of rising interest rates, while high-yield bonds, outstanding performers over recent quarters, also cooled off. Although the economic expansion continued to move ahead, investors were preoccupied with factors that might have undesirable impacts on the economy and the markets. For one thing, the threat of terrorism is never far from our minds. For another, the jump in oil prices, attributed to turmoil in the Mideast and vast demand from China and other developing nations, was a major factor. The cost of gas or oil for heating our homes, and gasoline for our cars is a critical component in household budgets. Industry, too, requires energy, and in many cases petroleum is an essential raw material. The "jobless" recovery became a job-generating machine for a few months, followed by a brief slump and a partial rebound. But strong boosts in employment quickly triggered fears of economic overheating; too much demand for goods and services, the reasons for aggressive corporate hiring, might trigger inflation. That would lead to higher interest rates that could choke off the recovery by causing consumers and businesses to hold back on outlays. In fact, on June 30, the Federal Reserve Board raised short-term interest rates by one-quarter percentage point, the first hike in four years. While there may be further increases, they probably will be gradual; the Federal Reserve Board would like to keep the expansion intact while keeping inflation at bay. And even after the Fed's June move, short-term rates remain near the lowest levels many of us have seen. U.S. businesses, which have done massive amounts of cost-cutting in recent years, can readily accommodate somewhat higher borrowing costs. In addition, the federal income tax cuts that have helped bolster growth over the past several quarters remain in place.

In the following interview, Christopher Galizio discusses the factors that affected the performance of Pioneer Growth Shares during the six-month period ended June 30, 2004. Mr. Galizio is a member of the Fund's management team. Q: How did the Fund perform during the first half of 2004? A: For the six-month period ended June 30, 2004, the Fund's Class A shares returned -1.31%, while Class B and Class C shares had returns of -1.80% and -1.78%, respectively, all at net asset value. For the same period, the Russell 1000 Growth Index returned 2.74%, while the average return was 2.35% for the 639 funds in the Large-Cap Growth Funds category tracked by Lipper Inc. (Lipper is an independent firm that measures mutual fund performance.) The Fund lagged the benchmark Russell 1000 Growth Index as well as the Lipper peer group, principally because of the comparatively larger position in technology, especially semiconductor companies, early in the six-month period. Q: What was the general investment environment like during the period? A: The overall market sentiment appeared to be turning negative late in the six-month period. The stock market surge that had begun in March 2003 appeared to lose some energy. Several major corporations, including ones in the retail and semiconductor industries, began to report earnings disappointments, and we saw some weakening in profit trends, notably in the consumer and technology sectors. Consumer spending trends, in particular, appeared weak as over-extended consumers finally began to retrench from their high-spending patterns. As stock market investors anticipated the June 30 announcement by the Federal Reserve Board that it would begin to tighten monetary policy by raising short-term interest rates, the share prices of some consumer-oriented financial institutions began to fade. Industrial stocks, however, tended to outperform the overall market. 8 Pioneer Growth Shares - -------------------------------------------------------------------------------- Q: What were your principal strategies during the period? A: We restructured the portfolio during the period, focusing on large-cap companies that we believed offered long-term value, above-average revenue growth, strong returns on capital and reasonable valuations in relation to their earnings potential. This strategy led to a reduced emphasis on the semiconductor industry and increased weightings in the software, consumer discretionary and financial services areas. We reduced our semi-conductor holdings, eliminating positions in Applied Materials, Cypress Semiconductor, Texas Instruments and Maxim Technology. We did add Taiwan Semiconductor, a major manufacturer with an attractive stock valuation. Overall, however, semiconductor stocks went from an overweight to an underweight position, relative to the benchmark S&P 500. The reduced weightings in technology tended to support performance. Conversely, we increased the portfolio's emphasis on software companies, adding companies such as Macrovision, which has developed a technology to protect DVDs, CDs and other disc-based products from piracy, as well as Take-Two Interactive, the developer of video games, including Grand Theft Auto - the most successful game in history, with a new version soon to be introduced. We also added Fair Isaac, which has developed software to help credit card companies analyze the credit-worthiness of applicants. Fair Isaac tended to detract from performance late in the six-month period as it reported disappointing earnings, but we continued to hold it because of its attractive valuation. We moved from an underweight to an overweight in the consumer discretionary sector, taking advantage of attractive valuations of Disney, whose media and theme park properties have improved earnings outlooks, and Viacom, the owner of the CBS and MTV television networks among other properties. Among retailers, we sold our Wal-Mart position before the stock fell hard, investing in Target, Kohl's and Ross Stores. In addition, we increased the emphasis on financial services stocks, focusing on insurance companies with excellent valuations that were not as vulnerable to interest-rate increases as banks and other lenders. 9 Pioneer Growth Shares - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/04 (continued) - -------------------------------------------------------------------------------- We continued to de-emphasize consumer staples, although we added Altria (the former Philip Morris), which offered a high dividend yield and an attractive stock price that we believed was the result of overly pessimistic market evaluations of the company's tobacco liability. In addition, we invested in First Data, the leader in processing of credit card transactions and owner of the Western Union system, and Accenture, an information-technology services consulting firm. Q: What were some of the investments that influenced performance? A: Among newer holdings, Macrovision rose significantly during the period as its revenue grew faster than had been expected. Sepracor, a pharmaceutical company and a new holding, also advanced on positive news of a drug under development. Zimmer Holdings, a world leader in orthopedic products, including hip and knee replacements, was another health-care position that did very well. The timely sale of Wal-Mart Stores also supported performance. The overweight position in the semiconductor industry early in the six-month period held back performance, as valuations in that group fell hard. Corinthian Colleges, operator of adult vocational educational colleges and programs, was another detractor, as the SEC began an investigation of its financial records. However, we took advantage of the price decline to add to the position in Corinthian because of its good long-term fundamentals. Lexar and Sandisk, two manufacturers of flash memories for cameras and cell phones, also fell on disappointing sales. Freeport-McMoRan, a leader in the copper mining industry and a strong support for performance in 2003, also declined both because of problems at one of its mines and because of fears of an economic slowdown in China, an important importer of copper. We increased our investment in the company because of its attractive price. We also believed it experienced some short-term production problems that would be resolved. Q: What is your investment outlook? A: We are cautious about the near-term opportunities in the domestic stock market, as stock valuations appear relatively expensive and 10 Pioneer Growth Shares - -------------------------------------------------------------------------------- the Federal Reserve Board has moved to a less accommodating monetary policy. The home refinancing boom of the past two years may hurt the future earnings of banks, while the technology industry faces a number of challenges, from pricing pressure on its products to calls to change the way many companies have treated stock options in their accounting. Health care stocks, however, appear to be more reasonably valued. Given this outlook, we are paying very strict attention to our analysis and selection of individual companies. We also have somewhat reduced our exposure to the domestic stock market with investments in Europe and the emerging markets. We have, for example, increased our position in Vodafone, the world's largest wireless communications service company, and we have added small holdings from Korea, Taiwan and Israel.

Organization and Significant Accounting Policies Pioneer Growth Shares (the Fund) is 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 to seek appreciation of capital. The Fund offers five classes of shares - Class A, Class B, Class C, Class R and Class Y shares. Class R shares were first publicly offered on April 1, 2003. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that each class of shares can bear different transfer agent and distribution fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B, Class C and Class R shareowners, respectively. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Fund, which are in conformity with those 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 is open, as of the close of regular trading on the Exchange. In computing the net asset value, securities are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. At June 30, 2004 there were no securities fair valued. Dividend income is recorded on the ex-dividend date 27 Pioneer Growth Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited) (continued) - -------------------------------------------------------------------------------- except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in exercise of reasonable diligence. Interest income is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Temporary cash investments are valued at amortized cost. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices, and currency rates or to seek to increase total return. Upon entering into a futures contract, the Fund is required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. Subsequent payments on futures contracts ("variation margin") are paid or received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract. The use of futures contracts involves, to varying degrees, elements of market risk which may exceed the amounts recognized by the Fund. Change in value of the contracts may not directly correlate to the change in value of the underlying securities. These risks may decrease the effectiveness of the Fund's hedging strategies and potentially result in a loss. At December 31, 2003 there were no open futures contracts. C. 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. 28 Pioneer Growth Shares - -------------------------------------------------------------------------------- The amount and characterization of distributions to shareowners for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source of the Fund's distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions paid will be determined at the end of the current fiscal year. There were no distributions paid during the year ended December 31, 2003. The following shows the components of accumulated losses on a federal income tax basis at December 31, 2003. - -------------------------------------------------------------------------------- 2003 - -------------------------------------------------------------------------------- Undistributed ordinary income $ - Capital loss carryforward (588,212,362) Post October losses deferred (3,689,033) Unrealized appreciation 32,418,824 ------------- Total $(559,482,571) ============= - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. D. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A (UniCredito Italiano), earned $77,807 in underwriting commissions on the sale of fund shares for the six months ended June 30, 2004. E. Class Allocations 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 shares are not subject to a distribution plan. Shareowners of each class share all expenses and fees paid to the transfer agent, Pioneer Investment 29 Pioneer Growth Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited) (continued) - -------------------------------------------------------------------------------- Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on their respective percentage of adjusted net assets at the beginning of the day. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner, at the same time, and in the same amount, except that Class A, Class B, Class C, Class R and Class Y shares can bear different transfer agent and distribution fees. F. Securities Lending The Fund lends securities in the Portfolio to certain broker-dealers or other institutional investors, with the Fund's custodian acting as the lending agent. When entering into a loan, the Fund receives collateral, which is maintained by the custodian and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or dividends on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for account of the Fund. The loans are secured by collateral of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in the Securities Lending Investment Fund, which is managed by Brown Brothers Harriman & Co., the Fund's custodian. G. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian, or subcustodians. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for 30 Pioneer Growth Shares - -------------------------------------------------------------------------------- determining that the value of the collateral remains at least equal to the repurchase price. 2. Management Agreement PIM manages the Fund's portfolio and is a wholly owned indirect subsidiary of UniCredito Italiano. Management fees are calculated daily at the annual rate of 0.70% of the Fund's average daily net assets up to $500 million; 0.65% of the next $500 million; and 0.625% of the excess over $1 billion. The basic fee is subject to a performance adjustment up to a maximum of [plus or minus]0.10% based on the Fund's Class A investment performance as compared with the Russell 1000 Growth Index. Pursuant to a shareowner vote on April 17, 2003, the benchmark index was changed from the Russell 1000 Index effective May 1, 2003; however, the Russell 1000 Index will be used for monthly periods prior to May 1, 2003 until it is eventually phased out. The performance comparison is made for a rolling 36-month period. For the six months ended June 30, 2004, the aggregate performance adjustment resulted in a decrease to the basic fee of $354,757. The management fee was equivalent to 0.59% of the average daily net assets. In addition, under the management and administrative agreements, certain other services and costs, including accounting, regulatory reporting, and insurance premiums, are paid by the Fund. At June 30, 2004, $418,591 was payable to PIM related to management fees, administrative fees and certain other services and is included in due to affiliates. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates is $536,065 in transfer agent fees payable to PIMSS at June 30, 2004. 4. Distribution and Service Plans The Fund adopted a Plan of Distribution for each class of shares (Class A Plan, Class B Plan, Class C Plan, and Class R Plan) in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Fund pays PFD 1.00% of the average 31 Pioneer Growth Shares - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/04 (unaudited) (continued) - -------------------------------------------------------------------------------- daily net assets attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Pursuant to the Class R Plan, the Fund pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in due to affiliates is $338,298 in distribution fees payable to PFD at June 30, 2004. 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 services organizations that agree to provide certain 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 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 one year of purchase. Class B shares that are redeemed within six years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%. Redemptions of Class R shares within 18 months of purchase may be subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the six months ended June 30, 2004, CDSCs in the amount of $196,246 were paid to PFD. 5. Expense Offset 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 June 30, 2004, the Fund's expenses were reduced by $14,542 under such arrangements. 32 Pioneer Growth Shares - -------------------------------------------------------------------------------- 6. Line Of Credit Facility The Fund, along with certain others in the Pioneer Family of Funds (the Funds), collectively participate in a $50 million 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 $50 million or the limits set by its prospectus for borrowings. Interest on collective borrowings is payable at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among such Funds based on their respective borrowing limits. For the six months ended June 30, 2004, the Fund had no borrowings under this agreement. 33 Pioneer Growth Shares - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Officers Trustees 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 recognizes 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 recognizes 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.
