Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides during the past year, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry, and to problems with risk management by banks
and hedge funds, have resulted in increased market volatility and rising
concern about risks to U.S. economic growth.

Even against this backdrop, the long-term performance of major asset classes
remained positive. In the 12 months ending August 31, 2007, equity investors
were generally rewarded as, despite a late-July decline, the Standard & Poor's
500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the
NASDAQ Composite Index returned 19%. International developed and emerging
markets equities performed well also, with the MSCI EAFE Developed Market Index
returning 19% and the MSCI Emerging Markets Index returning 44% over the
12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond
Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield
bond market, as measured by the Merrill Lynch High Yield Bond Master II Index,
returned 7% for the same period, reflecting its higher coupon yield.

U.S. economic growth has slowed in the past year, but this was due as much to
the natural maturation of the cyclical expansion, as U.S. factories approached
full utilization and the labor market approached full employment, as it was to
rising commodity prices and short-term interest rates. This slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher
inflation. More recently, however, there has been increasing concern that
falling home prices and/or banks' unwillingness to lend pose a larger and more
imminent threat to the economy.

In Europe, solid GDP growth driven by a positive operating environment for
European companies, especially exporters, has driven unemployment lower and
supported growing consumption. Japanese economic growth also continues to make
progress, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world as they persist in "catching up," led by China, which continues
its rise as a world economic power.

Letter



The U.S. Federal Reserve and the world's other central banks have pursued
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank policies have also been "investor friendly."
The central banks have responded to this past summer's liquidity squeeze in the
inter-bank and commercial paper markets by acting as the "lenders of last
resort" to limit the risk of problems spreading to the broader economy. Looking
forward, the economic outlook and equity valuations appear generally positive,
although the current environment is plagued by fears that subprime mortgage
problems will result in a systemic liquidity/credit crunch. While falling risk
tolerances may depress asset prices in the short term, valuations look
reasonable if credit market problems do not spread to the broader economy.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage
shareholders to work closely with their financial advisor to find the mix of
stocks, bonds and money market assets that is aligned to your particular risk
tolerance and investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 8/31/07
- --------------------------------------------------------------------------------

In the following interview, portfolio manager Piergaetano Iaccarino discusses
the factors that influenced performance for the 12-month fiscal period ended
August 31, 2007.


Q:  How did the Fund perform over the 12-month period ended August 31, 2007?

A:  The Fund's total return from September 1, 2006 through August 31, 2007 was
    14.58% (Class A shares at net asset value) versus 17.54% for the MSCI
    World Index. The global environment for equities was generally positive
    for the 12-month period, and this was reflected in the Fund's
    performance.

    Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most
    recent month-end performance results. Current performance may be lower or
    higher than the performance data quoted.

    The performance data quoted represents past performance, which is no
    guarantee of future results. Investment return and principal value will
    fluctuate, and shares, when redeemed, may be worth more or less than their
    original cost.

Q:  Can you review the Fund's overall investment approach?

A:  We look at mid- and large-capitalization stocks in more than 30 countries
    and from that universe build a somewhat concentrated portfolio of less
    than 50 stocks. Each stock that we hold will generally be overweighted by
    at least one percent versus the MSCI World Index. In selecting securities
    for the portfolio, we look for "growth at a reasonable price," so there
    is a strong value component to our analysis. We try to find companies
    that not only are benefiting from operating efficiencies as reflected in
    things like increased market share and revenues, but that also use their
    capital efficiently. In particular, we look for strong free cash flow,
    because this gives a company the flexibility to do things like make share
    buybacks, reinvest in the business, make acquisitions, and raise
    dividends. Finally, we try to assess not only the potential price gains
    for each stock, but also the potential for a decline in price if things
    go wrong and favor those stocks with the highest upside relative to their
    downside.

Q:  Could you characterize the global equity markets over the period?

A:  Global equity markets in the aggregate enjoyed strong positive returns over
    the period, despite periods of significant volatility. Markets declined
    sharply during the final week of February 2007. The drop began with a
    sharp decline in Chinese equities, based on rumors that the government
    would seek to tighten stock market investment rules and introduce a
    capital gains tax. The release of some weaker-than-expected U.S. economic
    data and evidence of mounting problems in the subprime U.S. mortgage
    market further added to a sense of unease among investors. As equity
    markets weakened, the Japanese yen rose strongly against the U.S. Dollar,
    which suggested that the broad-based decline in equities was partially
    due to the unwinding of so called "carry trades" funded through borrowing
    at low Japanese interest rates.

    As the second half of the fiscal period progressed, merger-and-acquisition
    activity helped restore a better tone to the equity markets, with most
    sectors experiencing some activity. In particular, there were significant
    deals announced in the banking, utilities and materials sectors. On the
    economic front, conditions in the United States remained consistent with
    growth that had been below trend, while European economic activity
    remained generally solid. In June 2007, global markets weakened, as
    stronger inflation and housing market data in the United States pushed
    interest rate expectations and bond yields higher. In addition, problems
    related to subprime mortgage exposure emerged at the hedge fund units of
    Bear Stearns and UBS, which added to risk aversion among investors. In
    July and August 2007, the full extent of the sub-prime issue began to come
    to light. It became clear that, due to rising defaults, the leading
    subprime lenders would not be able to meet their obligations to the Wall
    Street firms that repackage these loans and sell them to investors
    globally. The resulting credit crunch and heightened awareness of the
    global distribution of risk caused markets to drop sharply. As August
    progressed, equities began to make up some of the lost ground.

    European equities outperformed both U.S. and Japanese equities in the 12
    months ended August 31, 2007, helped in part by the strength of the euro
    relative to the U.S. Dollar. From a sector


                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 8/31/07                             (continued)
- --------------------------------------------------------------------------------

    perspective, the strongest areas in the global equity markets were
    materials, industrials and energy stocks, while the weakest returns were
    in the financials and consumer discretionary sectors.

Q:  What strategies or holdings helped and hurt performance over the fiscal
    period?

A:  Our sector allocation proved unrewarding on the whole, but stock selection
    was a larger factor in the Fund's somewhat lagging performance relative
    to the benchmark during the fiscal period.

    Our holdings in the financial sector, particularly among insurance
    companies, were among the leading detractors from the Fund's relative
    performance. We emphasized insurers during the fiscal year, and the
    leading underperformers among those holdings were AIG and MBIA, both of
    whom suffered from concerns over the impact of the subprime crisis on
    their bond insurance businesses. Among diversified financials, our
    holdings in Citigroup and Merrill Lynch were also penalized by market
    concerns over subprime loans, as well as over future bond issuance and
    trading volumes.

    In healthcare, we were modestly underweight on average for the fiscal
    period but overweight in pharmaceuticals companies. The pharmaceutical
    segment was weaker than the wider market, and this negative effect was
    compounded by the underperformance of our holdings, led by UK firm
    AstraZeneca. AstraZeneca's stock faltered in late 2006 after the company
    cancelled further development of a new stroke drug and lost patent
    protection on an ulcer drug in Europe. Bristol-Myers Squibb was the only
    positive contributor among pharmaceuticals in the fiscal period, as the
    patent on its leading blood-thinning drug Plavix was upheld by a U.S.
    court.

    Stock selection was also weak in the consumer discretionary
    sector during the fiscal period, where holdings in consumer durables such
    as Japanese companies Sekisui Chemical and Daito Trust Construction, fell
    strongly. Among retailers, Office Depot also acted as a drag on returns.

    The Fund benefited from positive stock selection in the telecommunications
    sector during the fiscal period, led by positions in Vodafone and Verizon.
    Vodafone rose sharply in the fiscal period, thanks to its
    better-than-expected profits guidance, which

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

    accompanied its full-year results in May. In the automobile sector, our
    holdings of Porsche advanced very strongly over the year, easily
    offsetting the negative relative returns from our position in Toyota.

    We deemphasized materials overall during the fiscal period, but our stock
    selection within the sector proved very successful. BASF, a German
    chemicals company, was the most successful stock pick in this area. Its
    second quarter results beat expectations, helped by higher prices and the
    contributions of acquisitions. The company is also in the midst of a large
    share buyback program. Mining company Rio Tinto also rose sharply amid
    merger rumors and continuing buoyant demand for metals from emerging
    markets.

Q:  What is your outlook and how is it reflected in the Fund?

A:  Looking ahead, global economic and company fundamentals remain supportive
    for equities. In general, global economic growth outside of the United
    States appears to be maintaining solid forward momentum, most notably in
    Europe and Asia. In the United States, the adjustment in housing and
    problems in the subprime mortgage sector are likely to remain headwinds
    for the economy, suggesting below-trend growth may persist. While equity
    valuations versus fixed-income are no longer as compelling following the
    recent increase in bond yields, particularly in the United States,
    current levels continue to justify an overall preference for equities in
    our view.

    Going forward, we will remain focused on identifying individual stocks
    that are reasonably priced and where we have high levels of conviction
    about the share price upside.

Investing in foreign and/or emerging markets securities involves certain risks,
including risks relating to interest rates, currency exchange rates, economic,
and political conditions. Investments in mid-sized companies may offer the
potential for higher returns, but are also subject to greater short-term price
fluctuations than larger, more established companies. The Fund is
non-diversified and invests in a limited number of securities and, as a result,
the Fund's performance may be more volatile than the performance of funds
holding more securities. At times, the Fund's investments may represent
industries or industry sectors that are interrelated or have


                                                                               7

regulatory developments or other risks affecting those industries and sectors.

month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that Pioneer
will extend the expense limitations beyond such time. Please see the prospectus
and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

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.

     and 2.20% for Class A, Class B and Class C shares, respectively, multiplied
     by the average account value over the period, multiplied by 184/365 (to
     reflect the one half year period).

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.

1.   Organization and Significant Accounting Policies

Pioneer Global Select Equity Fund (the Fund), is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory business trust
registered under the Investment Company Act of 1940 as an open-end management
investment company. The Fund is non-diversified. The Fund was organized on
October 12, 2005, and commenced operations on December 15, 2005. Prior to
October 12, 2005, the Fund had no operations other than those relating to
organizational matters and the initial capitalization of the Fund by Pioneer
Funds Distributor, Inc. (PFD). The fund's investment objective is to seek
long-term capital growth.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
Each class of shares represents an interest in the same portfolio of investments
of the Fund and has equal rights to voting, redemptions, dividends and
liquidation, except that each class of shares can bear different transfer agent
and distribution fees and has exclusive voting rights with respect to the
distribution plans that have been adopted by Class A, Class B and Class C
shareowners, respectively.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors. Information regarding the Fund's principal risk is
contained in the Fund's prospectus(es). Please refer to those documents when
considering the Fund's risks.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
income, expenses and gain or loss on investments during the reporting periods.
Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements which are

                                                                              29

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 8/31/07                              (continued)
- --------------------------------------------------------------------------------

consistent with those policies generally accepted in the investment company
industry:

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. In
     computing the net asset value, securities are valued using the last sale
     price on the principal exchange where they are traded. Securities that have
     not traded on the date of valuation, or securities for which sale prices
     are not generally reported, are valued using the mean between the last bid
     and asked prices. Securities for which market quotations are not readily
     available are valued at their fair values as determined by, or under the
     direction of, the Board of Trustees. The Fund invests primarily in
     securities of non-U.S. issuers. The principal exchanges and markets for
     such securities have closing times prior to the close of the NYSE. However,
     the value of these securities may be influenced by changes in global
     markets occurring after the closing times of the local exchanges and
     markets up to the time the Fund determines its net asset value.
     Consequently, the Board of Trustees of the Fund has determined that the use
     of daily fair valuations as provided by a pricing service is appropriate
     for the Fund. The Fund may also take into consideration other significant
     events in determining the fair value of these securities. Thus, the Fund's
     securities valuations may differ from prices reported by the various local
     exchanges and markets. Temporary cash investments are valued at cost which
     approximates market value.

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as Fund becomes aware of the ex-dividend data
     in exercise of reasonable diligence. Interest income, including interest on
     income bearing cash accounts, is recorded on the accrual basis, net of
     unrecoverable foreign taxes withheld at the applicable country rates.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

- --------------------------------------------------------------------------------

B.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as either from or in excess
     of net investment income or net realized gain on investment transactions,
     or from paid-in capital, depending on the type of book/tax differences that
     may exist.

     At August 31, 2007, the Fund reclassified $44 to decrease undistributed net
     investment income and $44 to increase accumulated net realized gain on
     investments to reflect permanent book/tax differences. The reclassification
     has no impact on the net asset value of the Fund and is designed to present
     the Fund's capital accounts on a tax basis.

     There were no distributions paid by the Fund during the period ended August
     31, 2006. The tax character of distributions paid during the year ended
     August 31, 2007 was as follows:

                                                                         -------

                                                                         =======

     The following shows the components of distributable earnings on a federal
     income tax basis at August 31, 2007.



- --------------------------------------------------------------------------------
                                                                          2007

Undistributed ordinary income                                           $ 85,596
Undistributed long-term gain                                             153,135
Unrealized appreciation                                                  163,019
                                                                        --------
  Total                                                                 $401,750
                                                                        ========
- --------------------------------------------------------------------------------


     The difference between book basis and tax-basis unrealized appreciation is
     attributable to the tax deferral of losses on wash sales.

C.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.,
     (UniCredito Italiano), earned $1,997 in underwriting commissions on the
     sale of Class A shares during the year ended August 31, 2007.

D.   Foreign Currency Translation

     The books and records of the Fund are maintained in U.S. dollars. Amounts
     denominated in foreign currencies are translated into U.S. dollars using
     current exchange rates. Net realized gains and losses on foreign currency
     transactions, if any, represent, among other things, the net realized gains
     and losses on foreign currency contracts, disposition of foreign currencies
     and the difference between the amount of income accrued and the U.S.
     dollars actually received. Further, the effects of changes in foreign
     currency exchange rates on investments are not segregated in the statement
     of operations from the effects of changes in market price of those
     securities but are included with the net realized and unrealized gain or
     loss on investments.

E.   Forward Foreign Currency Contracts

     The Fund enters into forward foreign currency contracts (contracts) for the
     purchase or sale of a specific foreign currency at a fixed price on a
     future date as a hedge or cross-hedge against either

32


Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

     specific investment transactions (settlement hedges) or portfolio positions
     (portfolio hedges). All contracts are marked to market daily at the
     applicable exchange rates, and any resulting unrealized gains or losses are
     recorded in the Fund's financial statements. The Fund records realized
     gains and losses at the time a portfolio hedge is offset by entry into a
     closing transaction or extinguished by delivery of the currency. Risks may
     arise upon entering into these contracts from the potential inability of
     counterparties to meet the terms of the contract and from unanticipated
     movements in the value of foreign currencies relative to the U.S. dollar.
     At August 31, 2007, the Fund had no outstanding portfolio hedges.

2.   Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.75% of the Fund's average daily net
assets up to $500 million; 0.70% of the next $500 million and 0.65% of the
excess over $1 billion. For the year ended August 31, 2007, the net management
fee was equivalent to 0.75% of the average daily net assets.

PIM has agreed not to impose all or a portion of its management fee and to
assume other operating expenses of the Fund to the extent necessary to limit the
Fund's expenses to 1.30%, 2.20% and 2.20% of the average daily net assets
attributable to Class A, Class B and Class C shares, respectively. These expense
limitations are in effect through January 1, 2009 for Class A and through
January 1, 2008 for Class B and Class C shares.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At August 31, 2007, $89 was payable to PIM
related to management fees, administrative costs and certain other services and
is included in due to affiliates.

3.   Transfer Agent

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredito Italiano, provides substantially all transfer
agent and shareowner services to the Fund at negotiated rates. Included in due
to affiliates is $1,984 in transfer agent fees payable to PIMSS at August 31,
2007.

                                                                              33

- --------------------------------------------------------------------------------

4.   Distribution Plans and Service Plans

The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the
Investment Company Act of 1940. The Fund pays PFD a service fee of up to 0.25%
of the average daily net assets attributable to Class A shares in reimbursement
of its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Included in due to affiliates is $71 in distribution fees payable to PFD
at August 31, 2007

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within 18 months of
purchase. Class B shares that are redeemed within five years of purchase are
subject to a CDSC at declining rates beginning at 4.00% based on the lower of
cost or market value of shares being redeemed. Redemptions of Class C shares
within one year of purchase are subject to a CDSC of 1.00%. Proceeds from the
CDSCs are paid to PFD. For the year ended August 31, 2007, CDSCs in the amount
of $237 were paid to PFD.

5.   New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than February 29, 2008. At this time, management is evaluating the
implications of

34


Pioneer Global Select Equity Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

FIN 48 and any impact in the financial statements has not yet been determined.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of SFAS
157 will have on the Fund's financial statement disclosures.

                                                                              35

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Global
Select Equity Fund:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Global Select Equity Fund (the Fund)
(one of the portfolios constituting Pioneer Series Trust V) as of August 31,
2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the periods indicated therein.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of August 31, 2007, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Global Select Equity Fund at August 31, 2007, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides during the past year, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry, and to problems with risk management by banks
and hedge funds, have resulted in increased market volatility and rising
concern about risks to U.S. economic growth.

Even against this backdrop, the long-term performance of major asset classes
remained positive. In the 12 months ending August 31, 2007, equity investors
were generally rewarded as, despite a late-July decline, the Standard & Poor's
500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the
NASDAQ Composite Index returned 19%. International developed and emerging
markets equities performed well also, with the MSCI EAFE Developed Market Index
returning 19% and the MSCI Emerging Markets Index returning 44% over the
12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond
Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield
bond market, as measured by the Merrill Lynch High Yield Bond Master II Index,
returned 7% for the same period, reflecting its higher coupon yield.

U.S. economic growth has slowed in the past year, but this was due as much to
the natural maturation of the cyclical expansion, as U.S. factories approached
full utilization and the labor market approached full employment, as it was to
rising commodity prices and short-term interest rates. This slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher
inflation. More recently, however, there has been increasing concern that
falling home prices and/or banks' unwillingness to lend pose a larger and more
imminent threat to the economy.

In Europe, solid GDP growth driven by a positive operating environment for
European companies, especially exporters, has driven unemployment lower and
supported growing consumption. Japanese economic growth also continues to make
progress, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world as they persist in "catching up," led by China, which continues
its rise as a world economic power.

Letter

The U.S. Federal Reserve and the world's other central banks have pursued
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank policies have also been "investor friendly."
The central banks have responded to this past summer's liquidity squeeze in the
inter-bank and commercial paper markets by acting as the "lenders of last
resort" to limit the risk of problems spreading to the broader economy. Looking
forward, the economic outlook and equity valuations appear generally positive,
although the current environment is plagued by fears that subprime mortgage
problems will result in a systemic liquidity/credit crunch. While falling risk
tolerances may depress asset prices in the short term, valuations look
reasonable if credit market problems do not spread to the broader economy.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage
shareholders to work closely with their financial advisor to find the mix of
stocks, bonds and money market assets that is aligned to your particular risk
tolerance and investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

Pioneer High Income Municipal Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 8/31/07
- --------------------------------------------------------------------------------

During a time of substantial market volatility, shareholders in Pioneer High
Income Municipal Fund were rewarded with a relatively high level of tax-free
income. In the following interview, portfolio manager Timothy Pynchon discusses
the factors that affected the municipal bond market and the Fund over the
semiannual period.

Q:   How did the Fund perform during the period ending August 31, 2007?

A:   For the six-month period ended August 31, 2007, Pioneer High Income
     Municipal Fund's Class A shares produced a total return of -2.49% at net
     asset value. The Fund's benchmark, the Lehman Brothers High Yield Municipal
     Bond Index, returned -1.89% for the same period, and the average return of
     the 95 funds in the Lipper High Yield Municipal Debt Funds category was
     -3.31% for the six-month period ended August 31, 2007. Lipper is an
     independent monitor of mutual fund performance. The Fund's Class A shares
     generated a 30-day SEC tax-free yield of 5.54%, based on the maximum income
     tax rate of 35%. At the end of the period, the Fund had 38 issues in 21
     states, and the average credit quality of the portfolio was BB.

     Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
     month-end performance results. Current performance may be lower or higher
     than the performance data quoted.

     The performance data quoted represents past performance, which is no
     guarantee of future results. Investment return and principal value will
     fluctuate, and shares, when redeemed, may be worth more or less than their
     original cost.

Q:   What was the investment backdrop like during the six months?

A:   The period can be divided into two distinct parts. For the first five
     months, high-yield municipal securities posted solid gains against a
     backdrop of relatively strong economic growth and relatively low interest
     rates. Investor demand was robust, as new types of investors, such as hedge
     funds, sought the higher tax-advantaged yields that below-investment-grade
     municipal bonds can provide. In August it became apparent that the subprime
     mortgage problem that had overshadowed the financial markets for several
     months was worse than originally thought. (Subprime mortgages are loans to
     less

     creditworthy buyers.) As some home owners defaulted on their mortgages, the
     lower-quality securities that were backed by those mortgages sold off, and
     investors lost confidence in the riskiest assets, which had been market
     leaders for more than a year.

     The volatility from subprime mortgage issues affected most of the
     fixed-income markets. Bond yields rose dramatically, and prices declined in
     a way that we had not seen in several years. In some cases bond yields rose
     80 to 120 basis points. (A basis point equals 0.01%.) The fixed-income
     market was in disarray for about three weeks, before it began to firm up
     and become more orderly. At the end of the period, the high-yield municipal
     bond market had been re-priced to levels that appeared appropriate for
     risky and non-rated assets.

Q:   How did you manage the Fund in this environment?

A:   We had no exposure to subprime mortgages during the period; however, the
     subprime mortgage problem affected virtually all fixed-income assets. While
     some of our positions lost value, we viewed the market volatility as an
     opportunity and positioned the Fund to deliver what we believe will be a
     strong total return in the future. As yields rose and prices declined, we
     sought to add yield and raise the credit quality of the portfolio. We
     traded some of the portfolio's non-rated credits for BBB-rated tobacco
     bonds, which we purchased at deep discounts and which we believe should
     benefit from capital appreciation. (Tobacco bonds are backed by tobacco
     companies' payments to states as part of the Master Settlement Agreement in
     which states agreed to drop their lawsuits against tobacco companies in
     return for a series of payments.)

     We kept the portfolio diversified among a variety of economic sectors. Some
     of the best yields were in the health care area, which was the biggest
     position in the portfolio. Health care is a large and growing part of the
     economy and encompasses several areas, such as hospitals, nursing homes and
     continuing care retirement communities, among others. The education,
     housing, transportation and water and sewer sectors were also represented
     in the portfolio. In selecting securities, we favored revenue bonds whose
     interest and principal are paid from the revenues derived from the

PORTFOLIO MANAGEMENT DISCUSSION 8/31/07                              (continued)
- --------------------------------------------------------------------------------

     bonds with relatively long maturities. About 27% of the portfolio's
     securities had maturities in the six to ten-year range, and about 57% had
     maturities of more than 10 years at the end of the fiscal period.

Q:   What influenced the Fund's performance?

A:   The impact of the subprime mortgage problem on the municipal bond market
     was unusual and broad. As investors grew concerned about a credit crunch,
     they traded out of lower quality high-yielding assets into high quality
     assets, such as Treasury securities. Because investors sought quality above
     everything else, demand for high-yielding municipal bonds, like the ones
     held by the portfolio, declined, and their prices went down. Even though
     the yields on the securities rose, the price erosion had a negative effect
     on the Fund's total return.

Q:   What is your outlook for the next six months?

A:   We are positive in our assessment for the high-yield municipal bond market
     over the next several months. As investors seek higher tax-advantaged
     yields, we expect demand for high-yield, lower-rated bonds to rise. During
     the recent market volatility, we restructured the portfolio, which we
     believe is poised to deliver a relatively high total return over the next
     several months.

Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. The Fund may invest in securities of issuers that
are in default or that are in bankruptcy.

A portion of the income may be subject to state, federal, and/or alternative
minimum tax. Capital gains, if any, are subject to a capital gains tax. The
fund is not diversified, which means that it can invest a higher percentage of
its assets in any one issuer than a diversified fund. Being non-diversified may
magnify the fund's losses from adverse events affecting a particular issuer. By
investing primarily in municipal securities, the portfolio is more susceptible
to adverse economic, political or regulatory developments than is a portfolio
that invests more broadly. Investments in the Fund are subject to possible loss
due to financial failure of underlying securities and their inability to meet
their debt obligations.

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.

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

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 are equal to the Fund's annualized expense ratio of 0.90%, 1.80%
     and 1.23% for Class A, Class C, and Class Y shares, respectively,
     multiplied by the average account value over the period, multiplied by
     184/365 (to reflect the half year period).

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.

NOTES TO FINANCIAL STATEMENTS 8/31/07

1. Organization and Significant Accounting Policies

Pioneer High Income Municipal Fund (the Fund) is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust registered under
the Investment Company Act of 1940 as an open-end management investment
company. The Fund is non-diversified. The Fund commenced operations on October
17, 2006. The investment objective of the Fund is to maximize total return
through a combination of income that is exempt from regular federal income tax
and capital appreciation.

The Fund offers three classes of shares designated as Class A, Class C, and
Class Y shares. Each class of shares represents an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidations, except that each class of shares can
bear different transfer agent and distribution fees and has exclusive voting
rights with respect to the distribution plans that have been adopted by Class A
and Class C shareowners, respectively. There is no distribution plan for Class
Y shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses, and gain or loss on investments during the
reporting period. Actual results could differ from those estimates.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors. More detailed descriptions of the Fund's principal
risks are contained in the Fund's prospectuses. Please refer to those documents
when considering the Fund's risks.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements which, are consistent with
those policies generally accepted in the investment company industry:


                                                                              27

NOTES TO FINANCIAL STATEMENTS 8/31/07                                (continued)
- --------------------------------------------------------------------------------

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. Securities
     are valued at prices supplied by independent pricing services, which
     consider such factors as Treasury spreads, yields, maturities and ratings.
     Valuations may be supplemented by dealers and other sources, as required.
     Securities for which there are no other readily available market quotations
     are valued at their fair values as determined by, or under the direction of
     the Board of Trustees. At August 31, 2007 there were no securities fair
     valued. Temporary cash investments are valued at cost which approximates
     market value.

     Discount and premium on debt securities are accreted or amortized,
     respectively, daily into interest income on a yield-to-maturity basis with
     a corresponding increase or decrease in the cost basis of the security.
     Interest income is recorded on the accrual basis.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

B.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income, exempt interest income, and net realized capital
     gains, if any, to its shareowners. Therefore, no federal tax provision is
     required.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as either from or in excess
     of net investment income or net realized gain on investment transactions,
     or from paid-in capital, depending on the type of book/tax differences that
     may exist.

     The Fund has elected to defer approximately $626,029 of capital losses
     recognized between November 1, 2006 and August 31, 2007 to its fiscal year
     ending August 31, 2008.

    The Fund has reclassified $3,254 to decrease paid-in capital, $296 to
    increase accumulated net realized loss on investments and $3,550 to
    increase undistributed net investment income to reflect permanent book/tax
    differences. The reclassification has no impact on the net asset value of
    the Fund and is designed to present the Fund's capital accounts on a tax
    basis.

    The tax character of distributions paid during the year ended August 31,
    2007 was as follows:

     The difference between book-basis and tax-basis unrealized appreciation is
     attributable to the tax basis adjustments on partnerships and the tax
     treatment of premium and amortization.

C.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.,
     (UniCredito Italiano), earned $11,099 in underwriting commissions on the
     sale of Class A shares during the period ended August 31, 2007.


                                                                              29

D.   Class Allocations

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A and Class C shares of the Fund, respectively (see
     Note 4). Class Y shares are not subject to a distribution plan. Shareowners
     of each class share all expenses and fees paid to the transfer agent,
     Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its
     services, which are allocated based on the number of accounts in each class
     and the ratable allocation of related out-of-pocket expenses (see Note 3).
     Income, common expenses and realized and unrealized gains and losses are
     calculated at the Fund level and allocated daily to each class of shares
     based on the respective percentage of adjusted net assets at the beginning
     of the day.

     The Fund declares, as daily dividends, substantially all of its net
     investment income. All dividends are paid on a monthly basis. Short-term
     capital gain distributions, if any, may be declared with the daily
     dividends. Distributions to shareowners are recorded as of the ex-dividend
     date. Distributions paid by the Fund with respect to each class of shares
     are calculated in the same manner, at the same time, and in the same
     amount, except that Class A, Class C, and Class Y shares can bear different
     transfer agent and distribution fees.

2.   Management Agreement

Pioneer Investment Management, Inc., (PIM), a wholly owned indirect subsidiary
of UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.50% of the Fund's average daily net
assets up to $500 million; 0.475% of the next $500 million; and 0.45% of the
excess over $1 billion. For the year ended August 31, 2007, the net management
fee was equivalent to 0.50% of average daily net assets.

PIM has agreed not to impose all or a portion of its management fee and to
assume other operating expenses (excluding taxes, commissions, interest and
extraordinary expenses) of the Fund to the extent necessary to limit expenses
to 0.90% and 1.80% of the average daily net assets attributable to Class A
shares and Class C shares, respectively. The Class A limitation is in effect
through January 1, 2009 and the Class C limitation is in effect through January
1, 2008.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At August 31, 2007, $342 was payable to PIM
related to management fees, administrative costs and certain other services and
is included in due to affiliates.

3.   Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareholder services to the Fund at
negotiated rates. Included in due to affiliates is $0 in transfer agent fees
payable from PIMSS at August 31, 2007.

4.   Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan
and Class C Plan) in accordance with Rule 12b-1 of the Investment Company Act
of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service fee of up to
0.25% of the average daily net assets attributable to Class A shares in
reimbursement of its actual expenditures to finance activities primarily
intended to result in the sale of Class A shares. Pursuant to the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to Class C
shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee
paid as compensation for personal services and/or account maintenance services
or distribution services with regard to Class C shares. Included in due to
affiliates is $216 in distribution fees payable to PFD at August 31, 2007.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 18 months of purchase. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to
PFD. There is no CDSC for Class Y shares. For the period ended August 31, 2007,
no CDSCs were paid to PFD.


                                                                              31

5.   Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result in a reduction in the Fund's total expenses due to interest earned
on cash held by PIMSS. For the period ended August 31, 2007, the Fund's
expenses were not reduced under such arrangements.

6.   New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than February 29, 2008. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Fund's financial statement disclosures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Pioneer Series Trust V and
Shareholders of Pioneer High Income Municipal Fund:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer High Income Municipal Fund (the Fund)
(one of the portfolios constituting Pioneer Series Trust V) as of August 31,
2007, and the related statement of operations, the statement of changes in net
assets, and the financial highlights for the period from October 17, 2006
(Commencement of Operations) to August 31, 2007. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audit included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of August 31, 2007, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer High Income Municipal Fund at August 31, 2007, the results of its
operations, the changes in its net assets, and the financial highlights for the
period from October 17, 2006 (Commencement of Operations) to August 31, 2007,
in conformity with U.S. generally accepted accounting principles.

Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides during the past year, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry, and to problems with risk management by banks
and hedge funds, have resulted in increased market volatility and rising concern
about risks to U.S. economic growth.

Even against this backdrop, the long-term performance of major asset classes
remained positive. In the 12 months ending August 31, 2007, equity investors
were generally rewarded as, despite a late-July decline, the Standard & Poor's
500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the
NASDAQ Composite Index returned 19%. International developed and emerging
markets equities performed well also, with the MSCI EAFE Developed Market Index
returning 19% and the MSCI Emerging Markets Index returning 44% over the
12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond
Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield
bond market, as measured by the Merrill Lynch High Yield Bond Master II Index,
returned 7% for the same period, reflecting its higher coupon yield.

U.S. economic growth has slowed in the past year, but this was due as much to
the natural maturation of the cyclical expansion, as U.S. factories approached
full utilization and the labor market approached full employment, as it was to
rising commodity prices and short-term interest rates. This slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher inflation.
More recently, however, there has been increasing concern that falling home
prices and/or banks' unwillingness to lend pose a larger and more imminent
threat to the economy.

In Europe, solid GDP growth driven by a positive operating environment for
European companies, especially exporters, has driven unemployment lower and
supported growing consumption. Japanese economic growth also continues to make
progress, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world as they persist in "catching up," led by China, which continues
its rise as a world economic power.

Letter

The U.S. Federal Reserve and the world's other central banks have pursued
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank policies have also been "investor friendly." The
central banks have responded to this past summer's liquidity squeeze in the
inter-bank and commercial paper markets by acting as the "lenders of last
resort" to limit the risk of problems spreading to the broader economy. Looking
forward, the economic outlook and equity valuations appear generally positive,
although the current environment is plagued by fears that subprime mortgage
problems will result in a systemic liquidity/credit crunch. While falling risk
tolerances may depress asset prices in the short term, valuations look
reasonable if credit market problems do not spread to the broader economy.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage
shareholders to work closely with their financial advisor to find the mix of
stocks, bonds and money market assets that is aligned to your particular risk
tolerance and investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 8/31/07
- --------------------------------------------------------------------------------

In the following interview, Robert McVicker, Pioneer Oak Ridge All Cap Growth
Fund's Lead Portfolio Manager, discusses the factors that influenced performance
during the period from the Fund's inception date of October 17, 2006 through
August 31, 2007.

Q:   How did the U.S. stock market perform during the reporting period, and how
     did this affect the performance of the Fund?

A:   Stocks delivered strong overall returns during this interval, masking the
     fact that the period was made up of two distinct parts. In the first part -
     covering the span from the Fund's inception through the end of June 2007 -
     individual stock performance was largely driven by the surge in merger and
     acquisition activity led by private equity firms, which purchase public
     companies at a premium in order to take them private. This phenomenon led
     to strong performance not just for companies that were acquired, but also
     for those seen as being likely acquisition targets. Since private equity
     firms tend to focus on companies that are ripe for restructuring - rather
     than those with the strongest fundamentals - lower-quality companies
     generally outperformed during this period. Given that our investment style
     focuses on superior companies with rising market share, a history of
     consistent earnings growth, and reasonable valuations, most of the stocks
     held in the Fund's portfolio did not benefit from takeover speculation
     during this acquisition-fueled rally. Even so, Class A shares of the Fund
     slightly outperformed the Fund's benchmark, the Russell 3000 Growth Index,
     from the Fund's inception through the end of June 2007.

     The second part, beginning in mid-July, saw investors' focus beginning to
     turn to the U.S. housing market, the problems in the sub-prime mortgage
     area, and the downturn of the global credit markets. The resulting increase
     in investors' risk aversion made it more difficult and expensive for
     private equity firms to borrow money to finance leveraged buyouts. A
     notable outcome of this shift was the beginning of a period of greater
     investor interest in higher-quality growth companies such as those held in
     the Fund. This enabled the Fund to extend its lead in terms of relative
     performance during the summer months. During the full period, the Class A
     shares of the Fund returned 11.90%, outpacing the 10.48% return of the
     benchmark, the Russell 3000 Growth Index.

     month-end performance results. Current performance may be lower or higher
     than the performance data quoted.

     The performance data quoted represents past performance, which is no
     guarantee of future results. Investment return and principal value will
     fluctuate, and shares, when redeemed, may be worth more or less than their
     original cost.

Q:   What factors helped and hurt performance during the reporting period?

A:   The Fund's performance was helped by the strength of our stock selection in
     the information technology, consumer discretionary, and industrials
     sectors. The primary area of underperformance was materials.

     With respect to individual stocks, the top contributor was Seattle-based
     Aquantive, an internet marketing company that received a takeover bid from
     Microsoft in mid-May at a substantial premium. Its shares, which stood at
     $35.87 on May 17, closed at $63.79 the following day. Eventually, Aquantive
     was acquired by Microsoft a few months later. Making the second-largest
     contribution was Gamestop, a retailer that sells new and used video games
     and consoles. Gamestop has benefited as consumers have upgraded their games
     following the release of improved systems such as the PS3, Wii, and Xbox
     360. The company has executed its business plan very well, and we believe
     more upside is ahead. Precision Castparts also was a strong performer for
     the Fund. A manufacturer of highly engineered industrial parts, the company
     has benefited from strong demand for cost efficient new planes like the
     Boeing 787, new airplane orders from emerging markets like China, and the
     need for replacements in aging fleets. Rounding out the list of leading
     contributors was Dade Behring, a maker of diagnostic lab equipment that was
     acquired by Siemens at a 30% premium in the final month of the reporting
     period; and Apple Computer, which has enjoyed strong sales across all of
     its product lines. We discuss the latter in greater detail below.

     The Fund's worst performer was Caremark Rx, now known as CVS Caremark
     following its merger with CVS. We believed this merger failed to
     appropriately value Caremark given its long track record

                                                                               5

     of effective execution and strong market performance. Given our concerns
     regarding the earnings outlook for the combined company, we elected to sell
     the stock in January. The second-largest detractor was Palomar Medical
     Technologies, a developer of laser-based hair removal systems. Although we
     believe the company's longer-term earnings prospects from joint ventures
     with Gillette and Johnson & Johnson are attractive, we elected to sell the
     stock based on our concerns about the likely slowing of Palomar's sales and
     profits. Also in the health care sector, Genentech underperformed due to
     investor worries about increased competition for several of its drugs.
     However, due to Genentech's outstanding pipeline of new drugs and our
     expectation that its leading cancer drug, Avastin, will continue to drive
     strong earnings growth, we decided to maintain the Fund's position as of
     the end of the reporting period.

Q:   In what areas have you been finding opportunities?

A:   The underperformance of higher-quality stocks throughout much of the past
     year afforded us the opportunity to purchase attractively-valued shares in
     the types of companies we favor. For instance, we added two technology
     companies - Adobe Systems and Apple - during pullbacks in the broader
     market. We believe Adobe will benefit from the introduction of the new
     Creative Suite 3 (CS3) product targeted to advertising firms. Adobe
     purchased the software company Macromedia in 2005, and CS3 is the first
     product release from the merged company. CS3 allows customers to create
     print and video media for the Internet and is Adobe's largest product
     launch ever. Apple, meanwhile, may be best known for its success in selling
     the iPod and iPhone, but it is also enjoying success selling its Mac
     computers. The Mac is especially popular with advertisers and design
     professionals, and we believe its sales will benefit further from the Adobe
     upgrade cycle. Since Apple has only a 4% to 5% market share in computers,
     even a small increase in this percentage would have a large impact on the
     company's earnings. We purchased Apple early in 2007, and the stock has
     already performed well for the Fund.

     We recently invested in Celgene, a biotechnology company with a very
     promising cancer drug called Revlimid. The drug has proven to be effective
     at fighting blood cancers, and there is evidence that it may work in
     treating solid tumors as well. We believe

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

     Revlimid has tremendous potential, which could result in rapid earnings
     growth for Celgene.

     IntercontinentalExchange, which operates an Internet-based global
     electronic marketplace for trading futures and commodities, is another new
     investment for the Fund. We initiated a position during the March
     correction in the broader market, giving us the opportunity to purchase
     shares at about a 20% discount from their previous highs. The company is a
     proven leader in the nascent over-the-counter (OTC) market for electronic
     trading of numerous commodities, including oil and natural gas. This market
     is expanding rapidly and we believe Intercontinental will be the main
     beneficiary among the exchanges.

Q:   What is your outlook for growth stocks?

A:   We expect that the overall market environment will continue to be
     characterized by worries about how the disruptions in the housing and
     credit markets will affect consumer spending and the U.S. economy as a
     whole. While we also believe overall corporate earnings growth will
     continue to slow, we expect continued strength in corporate spending will
     allow the U.S. economy to avoid a recession. On balance, we are cautiously
     optimistic based on positive corporate earnings prospects, the reasonable
     valuation level of the broader market, and our outlook for Federal Reserve
     policy.

     In our view, these factors point to a backdrop of slowing top-line sales
     and decreasing profit margins. In this environment, companies that can
     consistently deliver strong earnings growth likely will be harder to find -
     and thus be awarded higher valuations. We therefore believe the stage is
     set for higher-quality growth companies that exhibit superior sales and
     earnings growth to outperform the overall market, which could be beneficial
     for the Fund.

The Fund invests in a limited number of securities and, as a result, the Fund's
performance may be more volatile than the performance of other funds holding
more securities. At times, the Fund's investments may represent industries or
industry sectors that are interrelated or have common risks, making it more
susceptible to any economic, political, or regulatory developments or other
risks affecting those industries and sectors.

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.

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.

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.

1.   Organization and Significant Accounting Policies

Pioneer Oak Ridge All Cap Growth Fund (the Fund) is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is capital
appreciation.

The Fund offers three classes of shares - Class A, Class C and Class Y shares.
Class A, Class C and Class Y shares were first publicly offered on October 17,
2006. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has equal rights to voting, redemptions, dividends
and liquidation, except that the level of transfer agent and distribution fees
may differ among classes. Class A and Class C shareowners have exclusive voting
rights with respect to the distribution plan for each class. There is no
distribution plan for Class Y shares.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
income, expenses and gains and losses on investments during the reporting
period. Actual results could differ from those estimates.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors. Information regarding the Fund's principal risks are
contained in the Fund's prospectus. Please refer to those documents when
considering the Fund's risks.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular

                                                                              27


Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 8/31/07                              (continued)
- --------------------------------------------------------------------------------

     trading on the Exchange. In computing the net asset value, securities are
     valued at the last sale price on the principal exchange where they are
     traded. Securities that have not traded on the date of valuation, or
     securities for which sale prices are not generally reported, are valued at
     the mean between the last bid and asked prices. Securities for which market
     quotations are not readily available are valued at their fair values as
     determined by, or under the direction of, the Board of Trustees. Trading in
     foreign securities is substantially completed each day at various times
     prior to the close of the NYSE. The values of such securities used in
     computing the net asset value of the Fund's shares are determined as of
     such times. The Fund also may use the fair value of a security, including a
     non-U.S. security, when the closing market price on the principal exchange
     where the security is traded no longer reflects the value of the security.
     At August 31, 2007, there were no securities fair valued. Temporary cash
     investments are valued at cost which approximates market value

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in exercise of reasonable diligence. Dividend and interest income is
     recorded on the accrual basis, net of unrecoverable foreign taxes withheld
     at the applicable country rates.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

B.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as either from or in excess
     of net investment income or net

28


Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

     realized gain on investment transactions, or from paid-in capital,
     depending on the type of book/tax differences that may exist.

     The Fund has reclassified $7,187 to decrease accumulated net investment
     loss, $5,749 to decrease accumulated net realized loss on investments and
     $1,438 to decrease paid-in capital to reflect permanent book/tax
     differences. The reclassification has no impact on the net asset value of
     the Fund and is designed to present the Fund's capital accounts on a tax
     basis.

     There were no distributions paid during the period ended August 31, 2007.

     The following shows the components of distributable earnings on a federal
     income tax basis at August 31, 2007.



- --------------------------------------------------------------------------------
                                                                          2007
- --------------------------------------------------------------------------------
                                                                     
Unrealized appreciation                                                 $169,054
                                                                        --------
  Total                                                                 $169,054
                                                                        ========
- --------------------------------------------------------------------------------


     The difference between book-basis and tax-basis unrealized appreciation is
     attributable to the tax deferral of losses on wash sales.

C.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date.
     Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the
     Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A.
     (UniCredito Italiano), earned approximately $966 in underwriting
     commissions on the sale of Class A shares for the period ended August 31,
     2007.

D.   Class Allocations

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, and Class C shares of the Fund, respectively (see
     Note 4). Class Y shares are not subject to a distribution plan. Shareowners
     of each class share all expenses and fees paid to the transfer agent,
     Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its
     services, which are allocated based on the number of accounts in each class
     and the ratable allocation of related out-of-pocket expenses (see

                                                                              29

NOTES TO FINANCIAL STATEMENTS 8/31/07                              (continued)
- --------------------------------------------------------------------------------

     Note 3). Income, common expenses and realized and unrealized gains and
     losses are calculated at the Fund level and allocated daily to each class
     of shares based on the respective percentage of adjusted net assets at the
     beginning of the day.

     Distributions to shareowners are recorded as of the ex-dividend date.
     Distributions paid by the Fund with respect to each class of shares are
     calculated in the same manner, at the same time, on the same day, and in
     the same amount, except that Class A, Class C, and Class Y shares bear
     different transfer agent and distribution fees.

E.   Securities Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors, with the Fund's custodian acting as the
     lending agent. When entering into a loan, the Fund receives collateral,
     which is maintained by the custodian and earns income in the form of
     negotiated lenders' fees. The Fund also continues to receive interest or
     payments in lieu of dividends on the securities loaned. Gain or loss on the
     fair value of the loaned securities that may occur during the term of the
     loan will be for the account of the Fund. The loans are secured by
     collateral of at least 102%, at all times, of the fair value of the
     securities loaned. The amount of the collateral will be adjusted daily to
     reflect any price fluctuation in the value of the loaned securities. The
     Fund has the right under the lending agreements to recover the securities
     from the borrower on demand. The Fund invests cash collateral in the
     Securities Lending Investment Fund, which is sponsored by Brown Brothers
     Harriman & Co., the Fund's custodian.

2.   Management Agreement

PIM, a wholly owned subsidiary of UniCredito Italino, manages the Fund's
portfolio. PIM receives a basic fee that is calculated at the annual rate of
0.75% of the Fund's average daily net assets up to $500 million; and 0.70% on
assets over $500 million. The management fees were equivalent to 0.75% of the
average daily net assets for the period.

Pioneer has contractually agreed to limit ordinary operating expenses to the
extent required to reduce Fund expenses to 1.25% and 2.15% of the average daily
net assets attributable to Class A and Class C shares, respectively. These
expense limitations are in effect through

30


Pioneer Oak Ridge All Cap Growth Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

January 1, 2009 for Class A shares and through January 1, 2008 for Class C
shares. There is no expense limitation in effect for Class Y shares.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. On August 31, 2007, $41 was payable to PIM
related to management fees, administrative costs and certain other services, and
is included in due to affiliates.

3.   Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Fund at
negotiated rates. Included in due to affiliates is $447 in transfer agent fees
payable to PIMSS at August 31, 2007.

4.   Distribution and Service Plan

The Fund adopted a Plan of Distribution for Class A and Class C shares (Class A
Plan, and Class C Plan) in accordance with Rule 12b-1 under the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the average daily net assets attributable to Class A
shares in reimbursement of its actual expenditures to finance activities
primarily intended to result in the sale of Class A shares. Pursuant to the
Class C Plan, the Fund pays PFD 1.00% of the average daily net assets
attributable to each class of shares. The fee consists of a 0.25% service fee
and a 0.75% distribution fee paid as compensation for personal services and/or
account maintenance services or distribution services with regard to Class C
shares. Included in due to affiliates is $24 in distribution fees payable to PFD
at August 31, 2007.

In addition, redemptions of Class A and Class C shares may be subject to a
contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on
redemptions of certain net asset value purchases of Class A shares within 18
months of purchase. Redemptions of Class C shares within one year of purchase
are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the
period ended August 31, 2007, no CDSCs were paid to PFD.

                                                                              31

- --------------------------------------------------------------------------------

5.   Expense Offset Arrangements

The Fund has entered into an expense offset arrangement with PIMSS resulting in
a reduction in the Fund's total expenses due to interest earned on cash held by
PIMSS. For the period ended August 31, 2007, the Fund's expenses were not
reduced under such arrangement.

6.   New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than February 29, 2008. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of SFAS
157 will have on the Fund's financial statement disclosures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Pioneer Series Trust V and Shareholders of Pioneer Oak Ridge
All Cap Growth Fund:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Oak Ridge All Cap Growth Fund (the Fund)
(one of the portfolios constituting Pioneer Series Trust V) as of August 31,
2007, and the related statement of operations, the statement of changes in net
assets, and the financial highlights for the period from October 17, 2006
(Commencement of Operations) to August 31, 2007. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audit included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of August 31, 2007, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Oak Ridge All Cap Growth Fund at August 31, 2007, the results of its
operations, the changes in its net assets, and the financial highlights for the
period from October 17 (Commencement of Operations) to August 31, 2007, in
conformity with U.S. generally accepted accounting principles.

Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides during the past year, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry, and to problems with risk management by banks
and hedge funds, have resulted in increased market volatility and rising
concern about risks to U.S. economic growth.

Even against this backdrop, the long-term performance of major asset classes
remained positive. In the 12 months ending August 31, 2007, equity investors
were generally rewarded as, despite a late-July decline, the Standard & Poor's
500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the
NASDAQ Composite Index returned 19%. International developed and emerging
markets equities performed well also, with the MSCI EAFE Developed Market Index
returning 19% and the MSCI Emerging Markets Index returning 44% over the
12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond
Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield
bond market, as measured by the Merrill Lynch High Yield Bond Master II Index,
returned 7% for the same period, reflecting its higher coupon yield.

U.S. economic growth has slowed in the past year, but this was due as much to
the natural maturation of the cyclical expansion, as U.S. factories approached
full utilization and the labor market approached full employment, as it was to
rising commodity prices and short-term interest rates. This slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher
inflation. More recently, however, there has been increasing concern that
falling home prices and/or banks' unwillingness to lend pose a larger and more
imminent threat to the economy.

In Europe, solid GDP growth driven by a positive operating environment for
European companies, especially exporters, has driven unemployment lower and
supported growing consumption. Japanese economic growth also continues to make
progress, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world as they persist in "catching up," led by China, which continues
its rise as a world economic power.

Letter

The U.S. Federal Reserve and the world's other central banks have pursued
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank policies have also been "investor friendly."
The central banks have responded to this past summer's liquidity squeeze in the
inter-bank and commercial paper markets by acting as the "lenders of last
resort" to limit the risk of problems spreading to the broader economy. Looking
forward, the economic outlook and equity valuations appear generally positive,
although the current environment is plagued by fears that subprime mortgage
problems will result in a systemic liquidity/credit crunch. While falling risk
tolerances may depress asset prices in the short term, valuations look
reasonable if credit market problems do not spread to the broader economy.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage
shareholders to work closely with their financial advisor to find the mix of
stocks, bonds and money market assets that is aligned to your particular risk
tolerance and investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 8/31/07
- --------------------------------------------------------------------------------

The domestic equity market trended upward throughout the first 10 months of the
fiscal year ending August 31, 2007, but then reversed course in July 2007 and
became increasingly volatile over the final two months of the period. This
dramatic shift in the investment environment was brought on by fears about the
subprime mortgage industry and the potential impacts the industry's problems
might have on the larger economy. In the following interview, members of the
team responsible for managing Pioneer Select Research Growth Fund review the 12
months ending August 31, 2007. Diego Franzin, Ashesh Savla and John Peckham,
CFA, discuss the factors that affected Fund performance during the 12 months.
Mr. Franzin is Head of Pioneer's U.S. Quantitative Research & Management Group,
Mr. Savla, is a Quantitative Analyst at Pioneer, and Mr. Peckham is Pioneer's
Head of U.S. Equity Research.

Q:   How did the Fund perform during the 12 months ending August 31, 2007?

A:   Pioneer Select Research Growth Fund performed very well for the period,
     outpacing both its index and its competitive funds' peer group average. For
     the 12 months ending August 31, 2007, the Fund's Class A shares had a total
     return of 20.69%, at net asset value. During the same fiscal year, the
     benchmark Russell 1000 Growth Index returned 17.70%, and the average return
     of the 727 funds in Lipper's Large Cap Growth Fund category was 16.96%.

     month-end performance results. Current performance may be lower or higher
     than the performance data quoted.

     The performance data quoted represents past performance, which is no
     guarantee of future results. Investment return and principal value will
     fluctuate, and shares, when redeemed, may be worth more or less than their
     original cost.

Q:   What were the principal factors that influenced the Fund's performance
     during the 12 months?

A:   The Fund did well relative to its benchmark both when stocks rose during
     the 10 months -- from August 31, 2006 through June 30, 2007 -- and when the
     market became more volatile during July and August 2007. Stock selection
     was the key driver, consistent with

- --------------------------------------------------------------------------------

     the Fund's distinctive discipline. We typically maintain investments in 50
     different companies selected from the 100 stocks in the Pioneer Research
     Fund portfolio. Sector weightings are equal to those of the Russell 1000
     Growth Index, but we choose individual holdings from among all eligible
     stocks, whether part of the growth or value universe. In this process, we
     rank stocks based on our research into the superior characteristics of
     companies in 17 different sectors and industries. We believe the advantage
     of this process lies in its combination of both quantitative and
     qualitative research techniques. For example, when purely quantitative
     mutual funds in general struggled late in the fiscal year, this Fund
     enjoyed its best period relative to the Russell 1000 Growth Index.

Q:   What types of investments had the greatest influence on performance?

A:   Our selections in the health care, information technology and industrials
     sectors had the greatest positive impacts on results relative to the
     Russell 1000 Growth Index. On the negative side, our picks in the
     materials, financials and consumer staples sectors modestly underperformed
     the results in the same sectors in the Russell benchmark.

     In health care, the leading performers were pharmaceutical company Schering
     Plough and biotechnology leader Amgen. In addition, the fact that we did
     not own any shares of Johnson & Johnson - a major part of the Russell index
     - helped relative performance when that company performed poorly. Schering
     Plough gained in value as investors became more optimistic about its
     development pipeline of potential new drug products. We owned Amgen early
     in the year, when it performed very well, and then sold it before its stock
     price fell because of problems with an important anemia drug. Among our
     technology holdings, the top performers were Cisco Systems and Freescale
     Semiconductor. Cisco was the beneficiary of the continued expansion of
     corporate spending on information technology networks, while Freescale was
     bought out at a premium price by private equity investors. In the
     industrials sector, leading performers were equipment manufacturer Terex
     and railroad corporation Norfolk Southern. Terex, whose products include
     trucks and other heavy equipment used by industrial and utility
     corporations, performed well in the latter


                                                                               5

     stages of the current business cycle, while Norfolk Southern's earnings
     grew from strong demand for rail transportation services.

     In our materials selections, we did not own enough commodities companies -
     especially steel and other mining and minerals companies - during a period
     in which they performed very well. At the same time, we had too large a
     position in weak-performing Dow Chemical. Nevertheless, we did have an
     investment in Freeport McMoran Copper and Gold, a stellar performer for the
     period. In the financials sector, we had a large position in brokerage and
     investment banking leader Merrill Lynch, whose share price was affected by
     concerns about the health of corporate financing in the wake of the
     subprime mortgage crisis. In the consumer staples area, a notable
     underperformer was Church & Dwight, producer of a variety of personal care
     consumer products. We have maintained our position in the company as we
     believe that its fundamentals have remained sound, despite the
     underperformance.

Q:   What is your investment outlook?

A:   We remain optimistic about prospects in the market for several reasons: the
     economy has remained in its growth trajectory; both interest rates and
     inflation remain low by historical measures; and stock valuations appear
     reasonable. While the slump in the housing industry has been a drag on the
     economy, we do not believe it will pull the economy into a recession.
     Overall, we think the market continues to afford good opportunities for
     stock investing.

Investing in small and mid-sized companies may offer the potential for higher
returns, but are also subject to greater short-term price fluctuations than
larger, more established companies. The Fund invests in a limited number of
securities and, as a result, the Fund's performance may be more volatile than
the performance of other funds holding more securities. At times, the Fund's
investments may represent industries or industry sectors that are interrelated
or have common risks, making it more susceptible to any economic, political, or
regulatory developments or other risks affecting those industries and sectors.

Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that Pioneer
will extend the expense limitations beyond such time. Please see the prospectus
and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

The Russell 1000[RegTM] Growth Index measures the performance of large-cap U.S.
growth stocks. Index returns assume reinvestment of dividends and, unlike Fund
returns, do not reflect any fees, expenses or sales charges. You cannot invest
directly in an Index.

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.

     multiplied by 184/365 (to reflect the one-half year period).


                                                                              11

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.

NOTES TO FINANCIAL STATEMENTS 8/31/07

1.   Organization and Significant Accounting Policies
Pioneer Select Research Growth Fund (the Fund) is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund was organized on October 12, 2005, and commenced
operations on December 15, 2005. Prior to December 15, 2005, the Fund had no
operations other than those relating to organizational matters and the initial
capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). To date, no
shares have been offered to the public. The Fund shares outstanding at August
31, 2007, are owned by PFD. The Fund's investment objective is long-term capital
growth.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors. Information regarding the Fund's principal investment
risks is contained in the Fund's prospectus. Please refer to that document when
considering the Fund's investment risks.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
income, expenses and gain or loss on investments during the reporting period.
Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements which are consistent with
those policies generally accepted in the investment company industry:

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. In
     computing the net asset value, securities are valued at the last sale price
     on the principal exchange where they are traded. Securities that have not
     traded on the date of


                                                                              23


Pioneer Select Research Growth Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 8/31/07                              (continued)
- --------------------------------------------------------------------------------

     valuation, or securities for which sale prices are not generally reported,
     are valued at the mean between the last bid and asked prices. Securities
     for which market quotations are not readily available are valued at their
     fair values as determined by, or under the direction of, the Board of
     Trustees. Trading in foreign securities is substantially completed each day
     at various times prior to the close of the NYSE. The values of such
     securities used in computing the net asset value of the Fund's shares are
     determined as of such times. The Fund also may use the fair value of a
     security including a non-U.S. security when the closing market price on the
     principal exchange where the security is traded no longer reflects the
     value of the security. As of August 31, 2007, there were no securities fair
     valued. Temporary cash investments are valued at cost which approximates
     market value.

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in exercise of reasonable diligence. Interest income, including
     interest on income bearing cash accounts, is recorded on the accrual basis,
     net of unrecoverable foreign taxes withheld at the applicable country
     rates.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

B.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as either from or in excess
     of net investment income or net realized gain on investment transactions,
     or from paid-in capital, depending on the type of book/tax differences that
     may exist.

     At August 31, 2007, the Fund reclassified $73 to decrease distributions in
     excess of net investment income and $73 to decrease accumulated net
     realized gain on investments. The reclassification has no impact on the net
     asset value of the Fund and is designed to present the Fund's capital
     accounts on a tax basis.

     The tax character of distributions paid during the year ended August 31,
     2007 was as follows. There were no distributions paid during the period
     ended August 31, 2006.

- --------------------------------------------------------------------------------


C.   Securities Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors, with the Fund's custodian acting as the
     lending agent. When entering into a loan, the Fund receives collateral,
     which is maintained by the custodian and earns income in the form of
     negotiated lenders' fees. The Fund also continues to receive interest or
     payments in lieu of dividends on the securities loaned. Gain or loss on the
     fair value of the loaned securities that may occur during the term of the
     loan will be for the account of the Fund. The loans are secured by
     collateral of at least 102%, at all times, of the fair value of the
     securities loaned. The amount of the collateral will be adjusted daily to
     reflect any price fluctuation in the value of the loaned securities. The
     Fund has the right under the


                                                                              25

     lending agreements to recover the securities from the borrower on demand.
     The Fund invests cash collateral in the Securities Lending Investment Fund,
     which is sponsored by Brown Brothers Harriman & Co., the Fund's custodian.

2.   Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.75% of the Fund's average daily net
assets up to $1 billion and 0.70% on assets over $1 billion. For the year ended
August 31, 2007, the net management fee was equivalent to 0.75% of the average
daily net assets.

Through January 1, 2009, PIM has agreed not to impose its management fee and to
assume other operating expenses of the Fund to the extent necessary to limit
Class A expenses to 1.25% of the average daily net assets attributable to Class
A shares.

In addition, under the management and administration agreements, certain other
services, including accounting, regulatory reporting and insurance, are paid by
the Fund. At August 31, 2007, $231 was payable to PIM related to management
fees, administrative costs and certain other services and is included in due to
affiliates.


3.   Transfer Agent

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredito Italiano, provides substantially all transfer
agent and shareowner services to the Fund at negotiated rates. Included in due
to affiliates is $17 in transfer agent fees payable to PIMSS at August 31, 2007.

4.   Distribution Plan

The Fund adopted a Plan of Distribution in accordance with Rule 12b-1 of the
Investment Company Act of 1940. The Fund pays PFD a service fee of up to 0.25%
of the average daily net assets attributable to Class A shares in reimbursement
of its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. There were no distribution fees payable to PFD at
August 31, 2007.

5.   New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN
48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than February 29, 2008. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.


                                                                              27

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

To the Trustees of Pioneer Series Trust V and
Shareholders of Pioneer Select Research Growth Fund:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Select Research Growth Fund (the Fund)
(one of the portfolios constituting Pioneer Series Trust V) as of August 31,
2007, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the periods indicated therein.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of August 31, 2007, by correspondence with the custodian and
brokers. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Select Research Growth Fund at August 31, 2007, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

 Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides during the past year, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry, and to problems with risk management by banks
and hedge funds, have resulted in increased market volatility and rising
concern about risks to U.S. economic growth.

Even against this backdrop, the long-term performance of major asset classes
remained positive. In the 12 months ending August 31, 2007, equity investors
were generally rewarded as, despite a late-July decline, the Standard & Poor's
500 Index returned 15%, the Dow Jones Industrial Average returned 20%, and the
NASDAQ Composite Index returned 19%. International developed and emerging
markets equities performed well also, with the MSCI EAFE Developed Market Index
returning 19% and the MSCI Emerging Markets Index returning 44% over the
12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond
Index, returned 5% in the 12 months ending August 31, 2007. The U.S. high-yield
bond market, as measured by the Merrill Lynch High Yield Bond Master II Index,
returned 7% for the same period, reflecting its higher coupon yield.

U.S. economic growth has slowed in the past year, but this was due as much to
the natural maturation of the cyclical expansion, as U.S. factories approached
full utilization and the labor market approached full employment, as it was to
rising commodity prices and short-term interest rates. This slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher
inflation. More recently, however, there has been increasing concern that
falling home prices and/or banks' unwillingness to lend pose a larger and more
imminent threat to the economy.

In Europe, solid GDP growth driven by a positive operating environment for
European companies, especially exporters, has driven unemployment lower and
supported growing consumption. Japanese economic growth also continues to make
progress, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world as they persist in "catching up," led by China, which continues
its rise as a world economic power.

Letter

The U.S. Federal Reserve and the world's other central banks have pursued
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank policies have also been "investor friendly."
The central banks have responded to this past summer's liquidity squeeze in the
inter-bank and commercial paper markets by acting as the "lenders of last
resort" to limit the risk of problems spreading to the broader economy. Looking
forward, the economic outlook and equity valuations appear generally positive,
although the current environment is plagued by fears that subprime mortgage
problems will result in a systemic liquidity/credit crunch. While falling risk
tolerances may depress asset prices in the short term, valuations look
reasonable if credit market problems do not spread to the broader economy.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage
shareholders to work closely with their financial advisor to find the mix of
stocks, bonds and money market assets that is aligned to your particular risk
tolerance and investment objective.

Respectfully,

/s/Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 8/31/07
- --------------------------------------------------------------------------------

The domestic equity market generally moved upward for the first 10 months of
the past fiscal year before reversing direction in July 2007 and becoming
increasingly volatile over the final two months of the period that ended on
August 31, 2007. The late-period market turmoil was brought on by fears about
the subprime mortgage industry and its potential impacts on the larger economy.
In the following interview, members of the team responsible for managing
Pioneer Select Research Value Fund review the 12 months ending August 31, 2007.
Diego Franzin, Ashesh Savla and John Peckham, CFA, discuss the factors that
affected Fund performance. Mr. Franzin is Head of Pioneer's U.S. Quantitative
Research & Management Group, Mr. Savla, is a Quantitative Analyst at Pioneer,
and Mr. Peckham is Pioneer's Head of U.S. Equity Research.

Q:  How did the Fund perform during the 12 months ending August 31, 2007?

A:  The Fund did very well. For the 12 months ending August 31, 2007, Pioneer
    Select Research Value Fund's Class A shares had a total return of 16.24%,
    at net asset value. During the same fiscal year, the benchmark Russell
    1000 Value Index returned 12.85%, and the average return of the 497 funds
    in Lipper's Large Cap Value Fund category was 13.54%.

    recent month-end performance results. Current performance may be lower or
    higher than the performance data quoted.

    The performance data quoted represents past performance, which is no
    guarantee of future results. Investment return and principal value will
    fluctuate, and shares, when redeemed, may be worth more or less than their
    original cost.

Q:  What were the principal factors that influenced the Fund's performance
    during the 12 months?

A:  The Fund did well relative to its benchmark both when stocks rose during
    the 10 months - from August 31, 2006 through June 30, 2007 - and when the
    market became more volatile during July and August 2007. Stock selection
    was the key driver, consistent with the Fund's distinctive discipline. We
    typically maintain investments in 50 different companies selected from
    the 100 stocks in the

    Pioneer Research Fund portfolio. Sector weightings are equal to those of
    the Russell 1000 Value Index, but we choose individual holdings from among
    all eligible stocks, whether part of the growth or value universe. In this
    process, we rank stocks based on our research into the superior
    characteristics of companies in 17 different sectors and industries. We
    believe the advantage of this process lies in its combination of both
    quantitative and qualitative research techniques. For example, when purely
    quantitative mutual funds in general struggled late in the fiscal year,
    this Fund enjoyed its best period relative to the Russell 1000 Value
    Index.

Q:  What types of investments had the greatest influence on performance?

A:  Our selections in nine of the 10 market sectors outperformed the comparable
    group in the Russell 1000 Value Index. The top performing sectors in the
    Fund, relative to the benchmark, were health care, energy and financials.

    The top individual contributor was a health care company, Bristol-Myers
    Squibb. This global pharmaceutical company has an excellent pipeline of
    new drugs under development. In addition, the company came to be viewed as
    an attractive potential acquisition by a larger corporation. Also helping
    relative performance in the health care sector was our decision to avoid
    owning shares of Pfizer, another pharmaceutical company that performed
    poorly. In energy, three holdings in particular had outstanding
    performance. Marathon Oil's share price rose because of its strong
    position in the U.S. refining industry during a period of rising
    profitability for oil refiners. Weatherford International, an oil field
    services company, benefited from its leadership in new technologies that
    help oil companies increase their yields from individual wells. Finally,
    Chevron - a company whose stock we had purchased at a very attractive
    price - outperformed as it exceeded earnings expectations. In the
    financials sector, the leading performer was asset manager Franklin
    Resources, which gained as its mutual funds attracted a healthy flow of
    new investments.

    The only sector that underperformed relative to the benchmark index was
    materials. In that area, the problem was that we did not own enough
    commodities companies - especially steel and other


                                                                               5

    mining and minerals companies - during a period in which they performed
    very well.

Q:  What is your investment outlook?

A:  We remain optimistic about prospects in the market for several reasons: the
    economy has remained in its growth trajectory; both interest rates and
    inflation remain low by historical measures; and stock valuations appear
    reasonable. While the slump in the housing industry has been a drag on
    the economy, we do not believe it will pull the economy into a recession.
    Overall, we think the market continues to afford good opportunities for
    stock investing.

Investing in small and mid-sized companies may offer the potential for higher
returns, but are also subject to greater short-term price fluctuations than
larger, more established companies. The Fund invests in a limited number of
securities and, as a result, the Fund's performance may be more volatile than
the performance of other funds holding more securities. At times, the Fund's
investments may represent industries or industry sectors that are interrelated
or have common risks, making it more susceptible to any economic, political, or
regulatory developments or other risks affecting those industries and sectors.

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.

Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The net expense ratio reflects contractual expense limitations currently in
effect through 1/1/09 for Class A Shares. There can be no assurance that
Pioneer will extend the expense limitations beyond such time. Please see the
prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

The Russell 1000(R) Value Index measures the performance of large-cap U.S.
value stocks. Index returns assume reinvestment of dividends and, unlike Fund
returns, do not reflect any fees, expenses or sales charges. You cannot invest
directly in the Index.

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 are equal to the Fund's annualized expense ratio of 1.25% for Class
  A shares, multiplied by the average account value over the period,
  multiplied by 184/365 (to reflect the one-half year period).

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.

NOTES TO FINANCIAL STATEMENTS 8/31/07
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Select Research Value Fund (the Fund) is one of five portfolios
comprising Pioneer Series Trust V, a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund was organized on October 12, 2005, and commenced
operations on December 15, 2005. Prior to December 15, 2005, the Fund had no
operations other than those relating to organizational matters and the initial
capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). To date, no
shares have been offered to the public. The Fund shares outstanding at August
31, 2007, are owned by PFD. The Fund's investment objective is to seek long-term
capital growth.

Investing in small and mid-sized companies may offer the potential for higher
returns, but are also subject to greater short-term price fluctuations than
larger, more established companies. Information regarding the Fund's principal
investment risks is contained in the Fund's prospectus. Please refer to that
document when considering the Fund's investment risks.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gain or loss on investments during the
reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements which are consistent with
those policies generally accepted in the investment company industry:

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. In
     computing the net asset value, securities are valued at the last sale price
     on the principal exchange where they are traded. Securities that have not
     traded on the date of valuation, or securities for which sale prices are
     not generally reported,


                                                                              21


Pioneer Select Research Value Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 8/31/07                              (continued)
- --------------------------------------------------------------------------------

     are valued at the mean between the last bid and asked prices. Securities
     for which market quotations are not readily available are valued at their
     fair values as determined by, or under the direction of, the Board of
     Trustees. Trading in foreign securities is substantially completed each day
     at various times prior to the close of the NYSE. The values of such
     securities used in computing the net asset value of the Fund's shares are
     determined as of such times. The Fund also may use the fair value of a
     security including a non-U.S. security when the closing market price on the
     principal exchange where the security is traded no longer reflects the
     value of the security. As of August 31, 2007, there were no securities fair
     valued. Temporary cash investments are valued at cost which approximates
     market value.

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in exercise of reasonable diligence. Interest income, including
     interest on income bearing cash accounts, is recorded on the accrual basis,
     net of unrecoverable foreign taxes withheld at the applicable country
     rates.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

B.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as either from or in excess
     of net investment income or net realized gain on investment transactions,
     or from paid-in capital, depending on the type of book/tax differences that
     may exist.

     At August 31, 2007, the Fund reclassified $2 to decrease undistributed net
     investment income and $2 to increase accumulated


22


Pioneer Select Research Value Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

     net realized gain on investments. The reclassification has no impact on the
     net asset value of the Fund and is designed to present the Fund's capital
     accounts on a tax basis.

     The tax character of distributions paid during the year ended August 31,
     2007 was as follows. There were no distributions paid during the period
     ended August 31, 2006.

- --------------------------------------------------------------------------------


     The difference between book basis and tax basis unrealized appreciation is
     attributable to the tax deferral of losses on wash sales.

C.   Securities Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors, with the Fund's custodian acting as the
     lending agent. When entering into a loan, the Fund receives collateral,
     which is maintained by the custodian and earns income in the form of
     negotiated lenders' fees. The Fund also continues to receive interest or
     payments in lieu of dividends on the securities loaned. Gain or loss on the
     fair value of the loaned securities that may occur during the term of the
     loan will be for the account of the Fund. The loans are secured by
     collateral of at least 102%, at all times, of the fair value of the
     securities loaned. The amount of the collateral will be adjusted daily to
     reflect any price fluctuation in the value of the loaned securities. The
     Fund has the right under the


                                                                              23

     lending agreements to recover the securities from the borrower on demand.
     The Fund invests cash collateral in the Securities Lending Investment Fund,
     which is sponsored by Brown Brothers Harriman & Co., the Fund's custodian.

2.   Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary
of UniCredito Italiano, manages the Fund's portfolio. Management fees are
calculated daily at the annual rate of 0.75% of the Fund's average daily net
assets up to $1 billion and 0.70% of the excess over $1 billion. For the year
ended August 31, 2007, the management fee was equal to 0.75% of the Fund's
average daily net assets.

Through January 1, 2009, PIM has agreed not to impose all or a portion of its
management fee and to assume other operating expenses of the Fund to the extent
necessary to limit Class A expenses to 1.25% of the average daily net assets
attributable to Class A shares.

In addition, under the management and administration agreements, certain other
services, including accounting, regulatory reporting and insurance, are paid by
the Fund. There were no management fees, administrative costs or other services
payable at August 31, 2007.

3.   Transfer Agent

owned indirect subsidiary of UniCredito Italiano, provides substantially all

Investment Company Act of 1940. The Fund will pay PFD a service fee of up to
0.25% of the average daily net assets attributable to Class A shares in

intended to result in the sale of Class A shares. There were no distribution
fees payable to PFD at August 31, 2007.

5.   New Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Fund's tax returns to determine whether the tax positions have a
"more-likely-than-not" probability of being sustained by the applicable tax
authority. Tax positions deemed to not meet the more-likely-than-not threshold
would be recorded as a tax benefit or expense in the reporting period in which
they are realized. Adoption of FIN 48 is required for fiscal years beginning
after December 15, 2006 and is to be applied to all open tax years as of no
later than February 29, 2008. At this time, management is evaluating the
implications of FIN 48 and any impact in the financial statements has not yet
been determined.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.


                                                                              25

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of August 31, 2007, by correspondence with
the custodian and brokers. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Select Research Value Fund at August 31, 2007, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each
of the periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

 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.

                 firm, the scope of the Audit

GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

there were no services provided to an affiliate that required the Fund's
audit committee pre-approval.


(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements

with the adviser that provides ongoing services to the registrant for each of

defined, totaled approximately $39,100 in 2007 and $22,545 in 2006.

has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is

investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.
