             Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 1



President's Letter

Since 1928, active portfolio management based on in-depth, fundamental
research, has been the foundation of Amundi Pioneer's investment approach. We
believe an active management investment strategy is a prudent approach to
investing, especially during periods of market volatility, which can result
from any number of risk factors, including slow U.S. economic growth, rising
interest rates, and geopolitical factors. Of course, in today's global economy,
risk factors extend well beyond U.S. borders. In fact, it's not unusual for
political and economic issues on the international front to cause or contribute
to volatility in U.S. markets.

At Amundi Pioneer, each security under consideration is researched by our team
of experienced investment professionals, who communicate directly with the
management teams of those companies. At the end of this research process, if we
have conviction in a company's business model and management team, and regard
the security as a potentially solid investment opportunity, an Amundi Pioneer
portfolio manager makes an active decision to invest in that security. The
portfolio resulting from these decisions represents an expression of his or her
convictions, and strives to balance overall risk and return opportunity.

As an example, the Standard & Poor's 500 Index -- the predominant benchmark for
many U.S. Large-Cap Core Equity funds -- has 500 stocks. An Amundi Pioneer
portfolio manager chooses to invest in only those companies that he or she
believes can offer the most attractive opportunities to pursue the fund's
investment objective, thus potentially benefiting the fund's shareowners. This
process results in a portfolio that does not own all 500 stocks, but a much
narrower universe.

The same active decision to invest in a company is also applied when we decide
to sell a security, due to changing fundamentals, valuation concerns, or market
risks. We apply this active decision-making across all of our equity,
fixed-income, and global portfolios.

Today, as investors, we have many options. It is our view that active
management can serve shareholders well, not only when markets are thriving, but
also during periods of market volatility and uncertainty, thus making it a
compelling investment choice. As you consider the many choices today, we
encourage you to work with your financial advisor to develop an overall
investment plan that addresses both your short- and long-term goals, and to
implement such a plan in a disciplined manner.

continuing to serve you in the future.

Portfolio Management Discussion | 10/31/19

In the following interview, Andrew Feltus, Paresh Upadhyaya, and Bradley R.
Komenda, discuss the factors that affected the performance of Pioneer Global
Multisector Income Fund during the 12-month period ended October 31, 2019. Mr.
Feltus, CFA, Managing Director, Co-Director of High Yield, and a portfolio
manager at Amundi Pioneer Asset Management, Inc. (Amundi Pioneer), Mr.
Upadhyaya, Director of Currency Strategy, U.S., a senior vice president, and a
portfolio manager at Amundi Pioneer, and Mr. Komenda, Deputy Director of
Investment-Grade Corporates, a senior vice president, and a portfolio manager
at Amundi Pioneer, are responsible for the day-to-day management of the Fund,
along with Kenneth J. Taubes, Executive Vice President, Chief Investment
Officer, U.S., and a portfolio manager at Amundi Pioneer.

Q     How did the Fund perform during the 12-month period ended October 31,
      2019?

A     Pioneer Global Multisector Income Fund's Class A shares returned 5.89% at
      net asset value during the 12-month period ended October 31, 2019, while
      the Fund's benchmark, the Bloomberg Barclays Global Aggregate Bond Index
      (the Bloomberg Barclays Index), returned 9.54%. During the same period,
      the average return of the 216 mutual funds in Morningstar's World Bond
      Funds category was 7.72%.

Q     How would you describe the investment environment for fixed-income
      securities during the 12-month period ended October 31, 2019?

A     Global fixed-income markets delivered robust gains over the 12-month
      period, as a number of factors combined to fuel a broad-based rally in
      both interest-rate and credit-sensitive investments. The favorable
      backdrop stemmed, in part, from a persistent slowdown in global economic
      growth that gave central banks latitude to adopt easier monetary policies.
      In the United States, the U.S. Federal Reserve (Fed), after raising rates
      several times in 2018, adopted a more accommodative stance in early 2019
      while signaling that it had finished its tightening cycle, at least for
      the time being. The Fed eventually enacted three quarter-point rate cuts
      between August and October, bringing its benchmark federal funds rate down
      to a range of 1.50% of 1.75%. Many global central banks also adopted
      accommodative approaches, highlighted by the European Central Bank's (ECB)
      pledge to restart its quantitative easing policy. Those developments
      contributed to a decline in the 10-year U.S. Treasury yield, from 3.15% at
      the start of the 12-month period to 1.69% on October 31, 2019.

4 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



      Credit-sensitive segments of the fixed-income market produced strong
      returns during the 12-month period, with investment-grade corporates and
      emerging markets debt generating double-digit gains. High-yield bonds,
      while not keeping pace with the rest of the market, nonetheless posted a
      return in the high single digits. The credit-sensitive sectors benefited
      from the combination of positive economic growth, healthy corporate
      earnings, and elevated investor demand for higher-yielding debt. Given
      that a large swath of developed market government bonds offered negative
      yields during the 12-month period, investors gravitated to market segments
      featuring above-average income potential.

Q     What were the principal factors that either contributed to or detracted
      from the Fund's benchmark-relative returns during the 12-month period
      ended October 31, 2019?

A     Our decisions with respect to the portfolio's currency positioning played
      the largest role in the Fund's underperformance of the benchmark Bloomberg
      Barclays Index during the 12-month period. At the beginning of the fiscal
      year, we had positioned the Fund for a weaker U.S. dollar (USD), with
      allocations to the euro, Swedish krona, and Norwegian krone, among other
      currencies. The basis for the strategy was our view that economic growth
      in the world economy would begin to converge with that of the United
      States; but, in fact, the opposite occurred, which served to widen the gap
      between U.S. and European interest rates. That led to persistent strength
      in the USD, and so the long portfolio positions in certain emerging
      markets currencies further pressured the Fund's benchmark-relative
      returns.

      The Fund's duration positioning also detracted from benchmark-relative
      performance over the 12-month period. We maintained a shorter-duration
      stance in the portfolio versus the benchmark in both the United States and
      Europe, and during a 12-month period that saw yields fall significantly
      and bond prices rise, the positioning prevented the Fund from gaining the
      full benefit of the rally in the fixed-income markets. (Duration is a
      measure of the sensitivity of the price, or the value of principal, of a
      fixed-income investment to a change in interest rates, expressed as a
      number of years.)

      Our asset allocation decisions had a slightly negative effect on the
      Fund's benchmark-relative results as well. A position in Treasury
      Inflation-Protected Securities (TIPS) weighed on relative returns during
      the 12-month period, as inflation remained at subdued levels. An
      allocation to insurance-linked securities (ILS), which are debt
      instruments sponsored by property-and-casualty insurers to help mitigate
      the risk of having to pay claims in the wake of natural disasters, also
      detracted from the Fund's relative performance. We liked the ILS category
      in part due to the asset class's low correlation with the broader market.
      Unfortunately, that feature

             Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 5



      proved to be a negative performance factor during a period that saw strong
      returns in the major fixed-income categories. We significantly reduced the
      Fund's weighting in ILS as the period progressed, as we felt there were
      better opportunities in other areas of the market.

      On the positive side, security selection results were a net contributor to
      the Fund's benchmark-relative performance over the 12-month period. The
      Fund generated the best selection results in the emerging markets, with
      holdings in Ukraine and in supranational issues both making meaningful
      contributions to relative performance. The Europe/Middle East/Africa
      segment of the market was also a source of positive returns for the Fund,
      highlighted by positions in Egypt, Bahrain, Turkey, Senegal, and Kenya. A
      position in Argentina partially offset those contributions, however, as an
      unexpected result in that country's August presidential primary weighed
      heavily on its debt market. Within high yield, the Fund's holdings of
      industrial and banking issues were another positive contributor to
      benchmark-relative results. Finally, despite the overall underperformance
      from an asset allocation perspective, the Fund's exposure to the emerging
      markets aided benchmark-relative returns over the 12-month period.

Q     Did the Fund invest in any derivative securities during the 12-month
      period ended October 31, 2019? If so, did the derivatives have a material
      effect on benchmark-relative performance?

A     We invested the Fund invested in four types of derivatives during the
      12-month period: forward foreign currency contracts (currency forwards),
      foreign currency options, U.S. Treasury futures, and credit default swaps
      (CDS). Since we seek to achieve the portfolio's desired currency
      positioning with derivatives, the use of derivatives detracted from the
      Fund's benchmark-relative performance due to our bias towards a lower USD.
      However, the foreign currency option positions aided benchmark-relative
      results.

      We invested the portfolio in Treasury futures to help manage interest-rate
      risk, and that was a slight detractor from the Fund's relative returns.
      The CDS positions had a positive impact on Fund returns, due to the broad
      strength in the credit sectors over the 12-month period.

Q     Were there any changes in the Fund's distributions* to shareholders during
      the 12-month period ended October 31, 2019?

A     The Fund's monthly distribution rose over the 12-month period compared
      with the distribution level on October 31, 2018. The increase largely
      resulted from our additions to the portfolio's holdings of non-USD debt
      and certain currencies.

*     Distributions are not guaranteed.

6 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



Q     What is your outlook as we near the end of the calendar year, and how is
      the outlook reflected in the Fund's positioning?

A     The 12-month period ended with the Fund having a lower degree of currency
      exposure than it had maintained throughout most of the past year. However,
      we have remained prepared to rebuild the Fund's position in foreign
      currencies. We believe a catalyst for USD weakness could come in the form
      of improving relative economic growth trends overseas. We began to see
      evidence of a move in that direction late in the 12-month period with the
      stabilization of economic data across the international economies. At
      period-end, the Fund's foreign currency exposures primarily encompassed
      positions in the Japanese yen and select currencies in the emerging
      markets, including Russia, Turkey, India, and Indonesia.

      We have retained the Fund's lower-duration positioning in both the United
      States and Europe, based on the belief that yields had fallen too low and
      that the trades had become "crowded." If global economic growth is indeed
      improving, central banks will have less of a need to cut interest rates,
      meaning that yields in both regions could begin to move higher.

      From an allocation perspective, the Fund continues to have an overweight
      in the emerging markets, due to the above-average yields available in
      those economies and their ability to benefit from a potential improvement
      in global economic conditions. We are less enthusiastic on domestic
      high-yield investments, however, due to relatively full valuations in the
      asset class, but we are striving to capitalize on specific opportunities
      among the more higher-rated credits in the category. The Fund closed the
      12-month period with an underweight in investment-grade corporates, where
      the robust gains of the past year have led to a less favorable risk/return
      profile. In addition, we chose to reduce the Fund's weighting in senior
      bank loans, based on the expectation that their floating-rate features are
      likely to see lower investor demand now that the Fed appears to be in
      rate-cutting mode.

      The bond market and the USD both have experienced nearly uninterrupted
      rallies in the past year, but we do not believe it is reasonable to expect
      that the environment will remain so favorable indefinitely. As the
      investment backdrop evolves, we believe our flexible, selective investment
      approach can help us manage portfolio risk and help the Fund capitalize on
      potential values as they emerge.

Please refer to the Schedule of Investments on pages 17-39 for a full listing
of Fund securities.

All investments are subject to risk, including the possible loss of principal.
In the past several years, financial markets have experienced increased
volatility, depressed valuations, decreased liquidity and heightened
uncertainty. These conditions may continue, recur, worsen or spread.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, and economic and political
conditions.

When interest rates rise, the prices of fixed income securities held by the
Fund will generally fall. Conversely, when interest rates fall, the prices of
fixed income securities held by 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.

Investments in high-yield or lower rated securities are subject to
greater-than-average price volatility, illiquidity and possibility of default.

Prepayment risk is the chance that an issuer may exercise its right to prepay
its security, if falling interest rates prompt the issuer to do so. Forced to
reinvest the unanticipated proceeds at lower interest rates, the Fund would
experience a decline in income and lose the opportunity for additional price
appreciation.

The Fund may invest in mortgage-backed securities, which during times of
fluctuating interest rates may increase or decrease more than other
fixed-income securities. Mortgage-backed securities are also subject to
pre-payments.

The securities issued by U.S. Government-sponsored entities (e.g., FNMA,
Freddie Mac) are neither guaranteed nor issued by the U.S. Government.

Floating rate loans and similar instruments may be illiquid or less liquid than
other instruments, and the value of any collateral can decline or be
insufficient to meet the issuer's obligations.

The value of municipal securities can be adversely affected by changes in
financial condition of municipal issuers, lower revenues, and regulatory and
political developments.

The Fund is subject to currency risk, meaning that the Fund could experience
losses based on changes in the exchange rate between non-U.S. currencies and
the U.S. dollar.

The Fund may use derivatives, such as options, futures, inverse floating rate
obligations, swaps, and others, which can be illiquid, may disproportionately
increase losses, and have a potentially large impact on Fund performance.
Derivatives may have a leveraging effect on the Fund.

Index Definitions
--------------------------------------------------------------------------------
The Bloomberg Barclays Global Aggregate Bond Index is an unmanaged index that
provides a broad-based measure of the global investment-grade fixed-income
markets. Index returns are calculated monthly, assume reinvestment of dividends
and, unlike Fund returns, do not reflect any fees, expenses or sales charges.
It is not possible to invest directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts appearing on pages 12-14.

Call 1-800-225-6292 or visit www.amundipioneer.com/us 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. POP
returns reflect deduction of maximum 4.50% sales charge. NAV returns would have
been lower had sales charges been reflected. All results are historical and
assume the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

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

The net expense ratio reflects the contractual expense limitation currently in
effect through March 1, 2020, for Class A shares. There can be no assurance
that Amundi Pioneer will extend the expense limitation beyond such time. Please
see the prospectus and financial statements for more information.

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

Please refer to the financial highlights for more current expense ratios.

Call 1-800-225-6292 or visit www.amundipioneer.com/us 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.

Class Y shares are not subject to sales charges and are available for limited
groups of eligible investors, including institutional investors. All results
are historical and assume the reinvestment of dividends and capital gains.
Other share classes are available for which performance and expenses will
differ.

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

The net expense ratio reflects the contractual expense limitation currently in
effect through March 1, 2020, for Class Y shares. There can be no assurance
that Amundi Pioneer will extend the expense limitation beyond such time. Please
see the prospectus and financial statements for more information.

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

Please refer to the financial highlights for more current expense ratios.

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 1.00%, 1.84%,
      and 0.75% for Class A, Class C, and Class Y respectively, multiplied by
      the average account value over the period, multiplied by 184/365 (to
      reflect the partial 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.

            similar securities, interest rates, prepayment speeds, credit
            risks, etc.). See Notes to Financial Statements -- Note 1A.

  Level 3 - significant unobservable inputs (including the Fund's own
            assumptions in determining fair value of investments). See Notes to

Notes to Financial Statements | 10/31/19

1. Organization and Significant Accounting Policies

Pioneer Global Multisector Income Fund (the "Fund") is a series of Pioneer
Series Trust VII, a Delaware statutory trust. The Fund is registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The investment objective of the Fund is to provide a high level of
current income.

The Fund offers four classes of shares designated as Class A, Class C, Class K,
and Class Y shares. Class K had not commenced operations as of October 31,
2019. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
rates of class-specific fees and expenses, such as transfer agent and
distribution fees. Differences in class-specific fees and expenses will result
in differences in net investment income and, therefore, the payment of
different dividends from net investment income earned by each class. The
Amended and Restated Declaration of Trust of the Fund gives the Board of
Trustees the flexibility to specify either per-share voting or dollar-weighted
voting when submitting matters for shareowner approval. Under per-share voting,
each share of a class of the Fund is entitled to one vote. Under
dollar-weighted voting, a shareowner's voting power is determined not by the
number of shares owned, but by the dollar value of the shares on the record
date. Each share class has exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. There is no distribution plan for Class Y shares.

Amundi Pioneer Asset Management, Inc., an indirect, wholly owned subsidiary of
Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc., serves as the
Fund's investment adviser (the "Adviser"). Amundi Pioneer Distributor, Inc., an
affiliate of Amundi Pioneer Asset Management, Inc., serves as the Fund's
distributor (the "Distributor").

In August 2018, the Securities and Exchange Commission ("SEC") released a
Disclosure Update and Simplification Final Rule. The Final Rule amends
Regulation S-X disclosures requirements to conform them to U.S. Generally
Accepted Accounting Principles ("U.S. GAAP") for investment companies. The
Fund's financial statements were prepared in compliance with the new amendments
to Regulation S-X.

The Fund is an investment company and follows investment company accounting and
reporting guidance under U.S. GAAP. U.S. GAAP requires the management of the
Fund to make estimates and assumptions that affect the

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 47



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:

A.    Security Valuation

      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.

      Fixed-income securities are valued by using prices supplied by independent
      pricing services, which consider such factors as market prices, market
      events, quotations from one or more brokers, Treasury spreads, yields,
      maturities and ratings, or may use a pricing matrix or other fair value
      methods or techniques to provide an estimated value of the security or
      instrument. A pricing matrix is a means of valuing a debt security on the
      basis of current market prices for other debt securities, historical
      trading patterns in the market for fixed-income securities and/or other
      factors. Non-U.S. debt securities that are listed on an exchange will be
      valued at the bid price obtained from an independent third party pricing
      service. When independent third party pricing services are unable to
      supply prices, or when prices or market quotations are considered to be
      unreliable, the value of that security may be determined using quotations
      from one or more broker-dealers.

      Loan interests are valued in accordance with guidelines established by the
      Board of Trustees at the mean between the last available bid and asked
      prices from one or more brokers or dealers as obtained from Loan Pricing
      Corporation, an independent third party pricing service. If price
      information is not available from Loan Pricing Corporation, or if the
      price information is deemed to be unreliable, price information will be
      obtained from an alternative loan interest pricing service. If no reliable
      price quotes are available from either the primary or alternative pricing
      service, broker quotes will be solicited.

      Event-linked bonds or catastrophe bonds are valued at the bid price
      obtained from an independent third party pricing service. Other
      insurance-linked securities (including sidecars, collateralized
      reinsurance and industry loss warranties) may be valued at the bid price
      obtained from an independent pricing service, or through a third party
      using a pricing matrix, insurance industry valuation models, or other fair
      value methods or techniques to provide an estimated value of the
      instrument.

48 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



      Equity securities that have traded on an exchange are valued by using the
      last sale price on the principal exchange where they are traded. Equity
      securities that have not traded on the date of valuation, or securities
      for which sale prices are not available, generally are valued using the
      mean between the last bid and asked prices or, if both last bid and asked
      prices are not available, at the last quoted bid price. Last sale and bid
      and asked prices are provided by independent third party pricing services.
      In the case of equity securities not traded on an exchange, prices are
      typically determined by independent third party pricing services using a
      variety of techniques and methods.

      The value of foreign securities is translated into U.S. dollars based on
      foreign currency exchange rate quotations supplied by a third party
      pricing source. Trading in non-U.S. equity securities is substantially
      completed each day at various times prior to the close of the NYSE. The
      values of such securities used in computing the net asset value of the
      Fund's shares are determined as of such times. The Fund may use a fair
      value model developed by an independent pricing service to value non-U.S.
      equity securities.

      Options contracts are generally valued at the mean between the last bid
      and ask prices on the principal exchange where they are traded.
      Over-the-counter ("OTC") options and options on swaps ("swaptions") are
      valued using prices supplied by independent pricing services, which
      consider such factors as market prices, market events, quotations from one
      or more brokers, Treasury spreads, yields, maturities and ratings, or may
      use a pricing matrix or other fair value methods or techniques to provide
      an estimated value of the security or instrument.

      Forward foreign currency exchange contracts are valued daily using the
      foreign exchange rate or, for longer term forward contract positions, the
      spot currency rate and the forward points on a daily basis, in each case
      provided by a third party pricing service. Contracts whose forward
      settlement date falls between two quoted days are valued by interpolation.

      Futures contracts are generally valued at the closing settlement price
      established by the exchange on which they are traded.

      Swap contracts, including interest rate swaps, caps and floors (other than
      centrally cleared swap contracts), are valued at the dealer quotations
      obtained from reputable International Swap Dealers Association members.
      Centrally cleared swaps are valued at the daily settlement price provided
      by the central clearing counterparty.

      Shares of open-end registered investment companies (including money market
      mutual funds) are valued at such funds' net asset value. Shares of
      exchange-listed closed-end funds are valued by using the last sale price
      on the principal exchange where they are traded.

      Securities or loan interests for which independent pricing services or
      broker-dealers are unable to supply prices or for which market prices
      and/or quotations are not readily available or are considered to be
      unreliable are valued by a fair valuation team comprised of certain
      personnel of the Adviser pursuant to procedures adopted by the Fund's
      Board of Trustees. The Adviser's fair valuation team uses fair value
      methods approved by the Valuation Committee of the Board of Trustees. The
      Adviser's fair valuation team is responsible for monitoring developments
      that may impact fair valued securities and for discussing and assessing
      fair values on an ongoing basis, and at least quarterly, with the
      Valuation Committee of the Board of Trustees.

      Inputs used when applying fair value methods to value a security may
      include credit ratings, the financial condition of the company, current
      market conditions and comparable securities. The Fund may use fair value
      methods if it is determined that a significant event has occurred after
      the close of the exchange or market on which the security trades and prior
      to the determination of the Fund's net asset value. Examples of a
      significant event might include political or economic news, corporate
      restructurings, natural disasters, terrorist activity or trading halts.
      Thus, the valuation of the Fund's securities may differ significantly from
      exchange prices, and such differences could be material.

      At October 31, 2019, one security was valued using fair value methods (in
      addition to securities valued using prices supplied by independent pricing
      services, broker-dealers or using a third party insurance pricing model)
      representing 0.25% of net assets. The value of this fair valued security
      was $100,000.

B.    Investment Income and Transactions

      Dividend income is recorded on the ex-dividend date, except that certain
      dividends from foreign securities where the ex-dividend date may have
      passed are recorded as soon as the Fund becomes aware of the ex-dividend
      data in the exercise of reasonable diligence.

      Interest income, including interest on income-bearing cash accounts, is
      recorded on the accrual basis. Dividend and interest income are reported
      net of unrecoverable foreign taxes withheld at the applicable country
      rates and net of income accrued on defaulted securities.

      Interest and dividend income payable by delivery of additional shares is
      reclassified as PIK (payment-in-kind) income upon receipt and is included
      in interest and dividend income, respectively.

50 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



      Principal amounts of mortgage-backed securities are adjusted for monthly
      paydowns. Premiums and discounts related to certain mortgage-backed
      securities are amortized or accreted in proportion to the monthly
      paydowns. All discounts/premiums on purchase prices of debt securities are
      accreted/amortized for financial reporting purposes over the life of the
      respective securities, and such accretion/amortization is included in
      interest income.

      Security transactions are recorded as of trade date. Gains and losses on
      sales of investments are calculated on the identified cost method for both
      financial reporting and federal income tax purposes.

C.    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 exchange 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 on the Statement of
      Operations from the effects of changes in the market prices of those
      securities, but are included with the net realized and unrealized gain or
      loss on investments.

D.    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 net taxable income and net realized capital gains,
      if any, to its shareowners. Therefore, no provision for federal income
      taxes is required. As of October 31, 2019, the Fund did not accrue any
      interest or penalties with respect to uncertain tax positions, which, if
      applicable, would be recorded as an income tax expense on the Statement of
      Operations. Tax returns filed within the prior three years remain subject
      to examination by federal and state tax authorities.

      The amount and character of income and capital gain distributions to
      shareowners are determined in accordance with federal income tax rules,
      which may differ from U.S. GAAP. Distributions in excess of net investment
      income or net realized gains are temporary over distributions for
      financial statement purposes resulting from differences in the recognition
      or classification of income or distributions for financial statement and
      tax

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 51



      purposes. Capital accounts within the financial statements are adjusted
      for permanent book/tax differences to reflect tax character, but are not
      adjusted for temporary differences.

      At October 31, 2019, the Fund was permitted to carry forward indefinitely
      $50,253 of short-term and $399,073 of long-term losses under the Regulated
      Investment Company Modernization Act of 2010 without limitation.

      The tax character of distributions paid during the years ended October 31,
      2019 and October 31, 2018, were as follows:



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

      ==========================================================================


      The difference between book basis and tax basis unrealized depreciation is
      attributable to the tax deferral of losses on wash sales, the
      mark-to-market of foreign currency and futures contracts, adjustments
      relating to catastrophe bonds.

E.    Fund Shares

      The Fund records sales and repurchases of its shares as of trade date. The
      Distributor earned $566 in underwriting commissions on the sale of Class A
      shares during the year ended October 31, 2019.

F.    Class Allocations

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

      Distribution fees are calculated based on the average daily net asset
      value attributable to Class A and Class C shares of the Fund, respectively
      (see Note 4). Class Y shares do not pay distribution fees. All expenses
      and fees

52 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



      paid to the Fund's transfer agent for its services are allocated among the
      classes of shares based on the number of accounts in each class and the
      ratable allocation of related out-of-pocket expenses (see Note 3).

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

G.    Risks

      The value of securities held by the Fund may go up or down, sometimes
      rapidly or unpredictably, due to general market conditions, such as real
      or perceived adverse economic, political or regulatory conditions,
      inflation, changes in interest rates, lack of liquidity in the bond
      markets or adverse investor sentiment. In the past several years,
      financial markets have experienced increased volatility, depressed
      valuations, decreased liquidity and heightened uncertainty. These
      conditions may continue, recur, worsen or spread. A general rise in
      interest rates could adversely affect the price and liquidity of
      fixed-income securities and could also result in increased redemptions
      from the Fund.

      At times, the Fund's investments may represent industries or industry
      sectors that are interrelated or have common risks, making the Fund more
      susceptible to any economic, political, or regulatory developments or
      other risks affecting those industries and sectors. The Fund's investments
      in foreign markets and countries with limited developing markets may
      subject the Fund to a greater degree of risk than investments in a
      developed market. These risks include disruptive political or economic
      conditions and the imposition of adverse governmental laws or currency
      exchange restrictions.

      The Fund invests in below-investment-grade (high-yield) debt securities
      and preferred stocks. Some of these high-yield securities may be
      convertible into equity securities of the issuer. Debt securities rated
      below-investment-grade are commonly referred to as "junk bonds" and are
      considered speculative. These securities involve greater risk of loss, are
      subject to greater price volatility, and are less liquid, especially
      during periods of economic uncertainty or change, than higher rated debt
      securities.

      With the increased use of technologies such as the Internet to conduct
      business, the Fund is susceptible to operational, information security and
      related risks. While the Fund's Adviser has established business
      continuity

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 53



      plans in the event of, and risk management systems to prevent, limit or
      mitigate, such cyber-attacks, there are inherent limitations in such plans
      and systems, including the possibility that certain risks have not been
      identified. Furthermore, the Fund cannot control the cybersecurity plans
      and systems put in place by service providers to the Fund such as Brown
      Brothers Harriman & Co., the Fund's custodian and accounting agent, and
      DST Asset Manager Solutions, Inc., the Fund's transfer agent. In addition,
      many beneficial owners of Fund shares hold them through accounts at
      broker-dealers, retirement platforms and other financial market
      participants over which neither the Fund nor Amundi Pioneer exercises
      control. Each of these may in turn rely on service providers to them,
      which are also subject to the risk of cyber-attacks. Cybersecurity
      failures or breaches at Amundi Pioneer or the Fund's service providers or
      intermediaries have the ability to cause disruptions and impact business
      operations, potentially resulting in financial losses, interference with
      the Fund's ability to calculate its net asset value, impediments to
      trading, the inability of Fund shareowners to effect share purchases,
      redemptions or exchanges or receive distributions, loss of or unauthorized
      access to private shareowner information and violations of applicable
      privacy and other laws, regulatory fines, penalties, reputational damage,
      or additional compliance costs. Such costs and losses may not be covered
      under any insurance. In addition, maintaining vigilance against
      cyber-attacks may involve substantial costs over time, and system
      enhancements may themselves be subject to cyber-attacks.

      The Fund's prospectus contains unaudited information regarding the Fund's
      principal risks. Please refer to that document when considering the Fund's
      principal risks.

H.    Insurance-Linked Securities ("ILS")

      The Fund invests in ILS. The Fund could lose a portion or all of the
      principal it has invested in an ILS, and the right to additional interest
      or dividend payments with respect to the security, upon the occurrence of
      one or more trigger events, as defined within the terms of an
      insurance-linked security. Trigger events, generally, are hurricanes,
      earthquakes, or other natural events of a specific size or magnitude that
      occur in a designated geographic region during a specified time period,
      and/or that involve losses or other metrics that exceed a specific amount.
      There is no way to accurately predict whether a trigger event will occur,
      and accordingly, ILS carry significant risk. The Fund is entitled to
      receive principal, and interest and/or dividend payments so long as no
      trigger event occurs of the description and magnitude specified by the
      instrument. In addition to the specified trigger events, ILS may expose
      the Fund to other risks, including but not limited to issuer (credit)
      default, adverse regulatory or jurisdictional interpretations and adverse
      tax consequences.

54 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



      The Fund's investments in ILS may include event-linked bonds. ILS also may
      include special purpose vehicles ("SPVs") or similar instruments
      structured to comprise a portion of a reinsurer's catastrophe-oriented
      business, known as quota share instruments (sometimes referred to as
      reinsurance sidecars), or to provide reinsurance relating to specific
      risks to insurance or reinsurance companies through a collateralized
      instrument, known as collateralized reinsurance. Structured reinsurance
      investments also may include industry loss warranties ("ILWs"). A
      traditional ILW takes the form of a bilateral reinsurance contract, but
      there are also products that take the form of derivatives, collateralized
      structures, or exchange-traded instruments.

      Where the ILS are based on the performance of underlying reinsurance
      contracts, the Fund has limited transparency into the individual
      underlying contracts, and therefore must rely upon the risk assessment and
      sound underwriting practices of the issuer. Accordingly, it may be more
      difficult for the Adviser to fully evaluate the underlying risk profile of
      the Fund's structured reinsurance investments, and therefore the Fund's
      assets are placed at greater risk of loss than if the Adviser had more
      complete information. Structured reinsurance instruments generally will be
      considered illiquid securities by the Fund. These securities may be
      difficult to purchase, sell or unwind. Illiquid securities also may be
      difficult to value. If the Fund is forced to sell an illiquid asset, the
      Fund may be forced to sell at a loss.

      Additionally, the Fund may gain exposure to ILS by investing in a
      closed-end interval fund, Pioneer ILS Interval Fund, an affiliate of the
      Adviser. The Fund's investment in Pioneer ILS Interval Fund at October 31,
      2019, is listed in the Schedule of Investments.

I.    Purchased Options

      The Fund may purchase put and call options to seek to increase total
      return. Purchased call and put options entitle the Fund to buy and sell a
      specified number of shares or units of a particular security, currency or
      index at a specified price at a specific date or within a specific period
      of time. Upon the purchase of a call or put option, the premium paid by
      the Fund is included on the Statement of Assets and Liabilities as an
      investment. All premiums are marked-to-market daily, and any unrealized
      appreciation or depreciation is recorded on the Fund's Statement of
      Operations. As the purchaser of an index option, the Fund has the right to
      receive a cash payment equal to any depreciation in the value of the index
      below the strike price of the option (in the case of a put) or equal to
      any appreciation in the value of the index over the strike price of the
      option (in the case of a call) as of the valuation date of the option.
      Premiums paid for purchased call and put options which have expired are
      treated as realized losses on investments on the Statement of Operations.
      Upon the exercise or closing of a purchased put option, the premium is
      offset against the proceeds on the sale of the underlying security

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 55



      or financial instrument in order to determine the realized gain or loss on
      investments. Upon the exercise or closing of a purchased call option, the
      premium is added to the cost of the security or financial instrument. The
      risk associated with purchasing options is limited to the premium
      originally paid.

      The average market value of purchased options contracts open during the
      year ended October 31, 2019, was $66,269. Open purchased options at
      October 31, 2019, are listed in the Fund's Schedule of Investments.

J.    Option Writing

      The Fund may write put and covered call options to seek to increase total
      return. When an option is written, the Fund receives a premium and becomes
      obligated to purchase or sell the underlying security at a fixed price,
      upon the exercise of the option. When the Fund writes an option, an amount
      equal to the premium received by the Fund is recorded as "Written options
      outstanding" on the Statement of Assets and Liabilities and is
      subsequently adjusted to the current value of the option written. Premiums
      received from writing options that expire unexercised are treated by the
      Fund on the expiration date as realized gains from investments on the
      Statement of Operations. The difference between the premium and the amount
      paid on effecting a closing purchase transaction, including brokerage
      commissions, is also treated as a realized gain on the Statement of
      Operations, or, if the premium is less than the amount paid for the
      closing purchase transaction, as a realized loss on the Statement of
      Operations. If a call option is exercised, the premium is added to the
      proceeds from the sale of the underlying security in determining whether
      the Fund has realized a gain or loss. The Fund as writer of an option
      bears the market risk of an unfavorable change in the price of the
      security underlying the written option.

      The average market value of written options for the year ended October 31,
      2019, was $(6,412). Open written options contracts at October 31, 2019,
      are listed in the Fund's Schedule of Investments.

K.    Forward Foreign Currency Exchange Contracts

      The Fund may enter into forward foreign currency exchange contracts
      ("contracts") for the purchase or sale of a specific foreign currency at a
      fixed price on a future date. All contracts are marked-to-market daily at
      the applicable exchange rates, and any resulting unrealized appreciation
      or depreciation is recorded in the Fund's financial statements. The Fund
      records realized gains and losses at the time a contract is offset by
      entry into a closing transaction or extinguished by delivery of the
      currency. Risks may arise upon entering into these contracts from the
      potential inability of counterparties to meet the terms of the contract
      and from unanticipated movements in the value of foreign currencies
      relative to the U.S. dollar (see Note 7).

56 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



      At October 31, 2019, the Fund had entered into various forward foreign
      currency exchange contracts that obligated the Fund to deliver or take
      delivery of currencies at specified future maturity dates. Alternatively,
      prior to the settlement date of a forward foreign currency exchange
      contract, the Fund may close out such contract by entering into an
      offsetting contract.

      The average market value of forward foreign currency exchange contracts
      open during the year ended October 31, 2019, was $11,538,255. Open forward
      foreign currency exchange contracts outstanding at October 31, 2019, are
      listed in the Schedule of Investments.

L.    Futures Contracts

      The Fund may enter into futures transactions in order to attempt to hedge
      against changes in interest rates, securities prices and currency exchange
      rates or to seek to increase total return. Futures contracts are types of
      derivatives. All futures contracts entered into by the Fund are traded on
      a futures exchange. Upon entering into a futures contract, the Fund is
      required to deposit with a broker an amount of cash or securities equal to
      the minimum "initial margin" requirements of the associated futures
      exchange. The amount of cash deposited with the broker as collateral at
      October 31, 2019, is recorded as "Futures collateral" on the Statement of
      Assets and Liabilities.

      Subsequent payments for futures contracts ("variation margin") are paid or
      received by the Fund, depending on the daily fluctuation in the value of
      the contracts, and are recorded by the Fund as unrealized appreciation or
      depreciation. Cash received from or paid to the broker related to previous
      margin movement is held in a segregated account at the broker and is
      recorded as either "Due from broker for futures" or "Due to broker for
      futures" on the Statement of Assets and Liabilities. When the contract is
      closed, the Fund realizes a gain or loss equal to the difference between
      the opening and closing value of the contract as well as any fluctuation
      in foreign currency exchange rates where applicable. Futures contracts are
      subject to market risk, interest rate risk and currency exchange rate
      risk. Changes in value of the contracts may not directly correlate to the
      changes in value of the underlying securities. With futures, there is
      reduced counterparty credit risk to the Fund since futures are
      exchange-traded and the exchange's clearinghouse, as counterparty to all
      exchange-traded futures, guarantees the futures against default.

      The average market value of futures contracts open during the year ended
      October 31, 2019, was $(5,419,089). Open futures contracts outstanding at
      October 31, 2019, are listed in the Schedule of Investments.

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 57



M.    Credit Default Swap Contracts

      A credit default swap is a contract between a buyer of protection and a
      seller of protection against a pre-defined credit event or an underlying
      reference obligation, which may be a single security or a basket or index
      of securities. The Fund may buy or sell credit default swap contracts to
      seek to increase the Fund's income, or to attempt to hedge the risk of
      default on portfolio securities. A credit default swap index is used to
      hedge risk or take a position on a basket of credit entities or indices.

      As a seller of protection, the Fund would be required to pay the notional
      (or other agreed-upon) value of the referenced debt obligation to the
      counterparty in the event of a default by a U.S. or foreign corporate
      issuer of a debt obligation, which would likely result in a loss to the
      Fund. In return, the Fund would receive from the counterparty a periodic
      stream of payments during the term of the contract, provided that no event
      of default occurred. The maximum exposure of loss to the seller would be
      the notional value of the credit default swaps outstanding. If no default
      occurs, the Fund would keep the stream of payments and would have no
      payment obligation. The Fund may also buy credit default swap contracts in
      order to hedge against the risk of default of debt securities, in which
      case the Fund would function as the counterparty referenced above.

      As a buyer of protection, the Fund makes an upfront or periodic payment to
      the protection seller in exchange for the right to receive a contingent
      payment. An upfront payment made by the Fund, as the protection buyer, is
      recorded within the "Swap contracts, at value" line item on the Statement
      of Assets and Liabilities. Periodic payments received or paid by the Fund
      are recorded as realized gains or losses on the Statement of Operations.

      Credit default swap contracts are marked-to-market daily using valuations
      supplied by independent sources, and the change in value, if any, is
      recorded within the "Swap contracts, at value" line item on the Statement
      of Assets and Liabilities. Payments received or made as a result of a
      credit event or upon termination of the contract are recognized, net of
      the appropriate amount of the upfront payment, as realized gains or losses
      on the Statement of Operations.

      Credit default swap contracts involving the sale of protection may involve
      greater risks than if the Fund had invested in the referenced debt
      instrument directly. Credit default swap contracts are subject to general
      market risk, liquidity risk, counterparty risk and credit risk. If the
      Fund is a protection buyer and no credit event occurs, it will lose its
      investment. If the Fund is a protection seller and a credit event occurs,
      the value of the referenced debt instrument received by the Fund, together
      with the periodic payments

58 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



      received, may be less than the amount the Fund pays to the protection
      buyer, resulting in a loss to the Fund. In addition, obligations under
      sell protection credit default swaps may be partially offset by net
      amounts received from settlement of buy protection credit default swaps
      entered into by the Fund for the same reference obligation with the same
      counterparty.

      Certain swap contracts that are cleared through a central clearinghouse
      are referred to as centrally cleared swaps. All payments made or received
      by the Fund are pursuant to a centrally cleared swap contract with the
      central clearing party rather than the original counterparty. Upon
      entering into a centrally cleared swap contract, the Fund is required to
      make an initial margin deposit, either in cash or in securities. The daily
      change in value on open centrally cleared contracts is recorded as
      "Variation margin for centrally cleared swaps" on the Statement of Assets
      and Liabilities. Cash received from or paid to the broker related to
      previous margin movement is held in a segregated account at the broker and
      is recorded as either "Due from broker for swaps" or "Due to broker for
      swaps" on the Statement of Assets and Liabilities. The amount of cash
      deposited with a broker as collateral at October 31, 2019, is recorded as
      "Swaps collateral" on the Statement of Assets and Liabilities.

      The average market value of credit default swap contracts open during the
      year ended October 31, 2019, was $22,702. There were no open credit
      default swap contracts at October 31, 2019.

2. Management Agreement

The Adviser manages the Fund's portfolio. Effective October 1, 2018, management
fees are calculated daily at the annual rate of 0.50% of the Fund's average
daily net assets up to $1 billion and 0.45% of the Fund's average daily net
assets over $1 billion. Prior to October 1, 2018, Management fees were
calculated daily at the annual rate of 0.50% of the Fund's average daily net
assets. For the year ended October 31, 2019, the effective management fee
(excluding waivers and/or assumption of expenses) was equivalent to 0.44% of
the Fund's average daily net assets.

The Adviser has agreed to waive its management fee with respect to any portion
of the Fund's assets invested in Pioneer ILS Interval Fund, an affiliated fund
managed by the Adviser. For the year ended October 31, 2019, the Adviser waived
$26,095 in management fees with respect to the Fund, which is reflected on the
Statement of Operations as an expense waiver.

The Adviser has contractually agreed to limit ordinary operating expenses
(ordinary operating expenses means all fund expenses other than extraordinary
expenses, such as litigation, taxes, brokerage commissions and acquired fund
fees and expenses) of the Fund to the extent required to reduce

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 59



Fund expenses to 1.00%, 1.90% and 0.75% of the average daily net assets
attributable to Class A, Class C and Class Y shares, respectively. These
expense limitations are in effect through March 1, 2020. There can be no
assurance that the Adviser will extend the expense limitation agreement beyond
the date referred to above. Fees waived and expenses reimbursed during the year
ended October 31, 2019, are reflected on the Statement of Operations.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$14,622 in management fees, administrative costs and certain other
reimbursements payable to the Adviser at October 31, 2019.

3. Transfer Agent

DST Asset Manager Solutions, Inc. serves as the transfer agent to the Fund at
negotiated rates. Transfer agent fees and payables shown on the Statement of
Operations and the Statement of Assets and Liabilities, respectively, include
sub-transfer agent expenses incurred through the Fund's omnibus relationship
contracts.

In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareowner communications activities
such as proxy and statement mailings, and outgoing phone calls. For the year
ended October 31, 2019, such out-of-pocket expenses by class of shares were as
follows:



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

================================================================================


4. Distribution and Service Plans

The Fund has adopted a distribution plan (the "Plan") pursuant to Rule 12b-1 of
the Investment Company Act of 1940 with respect to its Class A and Class C
shares. Pursuant to the Plan, the Fund pays the Distributor 0.25% of the
average daily net assets attributable to Class A shares as compensation for
personal services and/or account maintenance services or distribution services
with regard to Class A shares. Pursuant to the Plan, the Fund also pays the
Distributor 1.00% of the average daily net assets attributable to Class C
shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or

60 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



distribution services with regard to Class C shares. Included in "Due to
affiliates" reflected on the Statement of Assets and Liabilities is $1,068 in
distribution fees payable to the Distributor at October 31, 2019.

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 12
months of purchase. Redemptions of Class C shares within 12 months of purchase
are subject to a CDSC of 1.00%, based on the lower of cost or market value of
shares being redeemed. Shares purchased as part of an exchange remain subject
to any CDSC that applied to the original purchase of those shares. There is no
CDSC for Class Y shares. Proceeds from the CDSCs are paid to the Distributor.
For the year ended October 31, 2019, CDSCs in the amount of $112 were paid to
the Distributor.

5. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
"Funds"), participates in a committed, unsecured revolving line of credit
facility. Borrowings are used solely for temporary or emergency purposes. The
Fund may borrow up to the lesser of the amount available under the credit
facility or the limits set for borrowing by the Fund's prospectus and the 1940
Act. Effective August 1, 2018, the Fund participates in a credit facility in
the amount of $250 million. Under such facility, depending on the type of loan,
interest on borrowings is payable at the London Interbank Offered Rate
("LIBOR") plus a credit spread. The Funds also pay an annual commitment fee to
participate in a credit facility. The commitment fee is allocated among
participating Funds based on an allocation schedule set forth in the credit
agreement. For the year ended October 31, 2019, the Fund had no borrowings
under the credit facility.

6. Master Netting Agreements

The Fund has entered into an International Swaps and Derivatives Association,
Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with
substantially all of its derivative counterparties. An ISDA Master Agreement is
a bilateral agreement between the Fund and a counterparty that governs the
trading of certain Over the Counter ("OTC") derivatives and typically contains,
among other things, close-out and set-off provisions which apply upon the
occurrence of an event of default and/or a termination event as defined under
the relevant ISDA Master Agreement. The ISDA Master Agreement may also give a
party the right to terminate all transactions traded under such agreement if,
among other things, there is deterioration in the credit quality of the other
party.

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 61



Upon an event of default or a termination of the ISDA Master Agreement, the
non-defaulting party has the right to close-out all transactions under such
agreement and to net amounts owed under each transaction to determine one net
amount payable by one party to the other. The right to close out and net
payments across all transactions under the ISDA Master Agreement could result
in a reduction of the Fund's credit risk to its counterparty equal to any
amounts payable by the Fund under the applicable transactions, if any. However,
the Fund's right to set-off may be restricted or prohibited by the bankruptcy
or insolvency laws of the particular jurisdiction to which each specific ISDA
Master Agreement of each counterparty is subject.

The collateral requirements for derivatives transactions under an ISDA Master
Agreement are governed by a credit support annex to the ISDA Master Agreement.
Collateral requirements are generally determined at the close of business each
day and are typically based on changes in market values for each transaction
under an ISDA Master Agreement and netted into one amount for such agreement.
Generally, the amount of collateral due from or to a counterparty is subject to
threshold (a "minimum transfer amount") before a transfer is required, which
may vary by counterparty. Collateral pledged for the benefit of the Fund and/or
counterparty is held in segregated accounts by the Fund's custodian and cannot
be sold, re-pledged, assigned or otherwise used while pledged. Cash that has
been segregated to cover the Fund's collateral obligations, if any, will be
reported separately on the Statement of Assets and Liabilities as "Swaps
collateral". Securities pledged by the Fund as collateral, if any, are
identified as such in the Schedule of Investments.

Financial instruments subject to an enforceable master netting agreement, such
as an ISDA Master Agreement, have been offset on the Statement of Assets and
Liabilities. The following charts show gross assets and liabilities of the Fund
as of October 31, 2019.

7. Additional Disclosures about Derivative Instruments and Hedging Activities

The Fund's use of derivatives may enhance or mitigate the Fund's exposure to
the following risks:

Interest rate risk relates to the fluctuations in the value of interest-bearing
securities due to changes in the prevailing levels of market interest rates.

Credit risk relates to the ability of the issuer of a financial instrument to
make further principal or interest payments on an obligation or commitment that
it has to the Fund.

Foreign exchange rate risk relates to fluctuations in the value of an asset or
liability due to changes in currency exchange rates.

Equity risk relates to the fluctuations in the value of financial instruments
as a result of changes in market prices (other than those arising from interest
rate risk or foreign exchange rate risk), whether caused by factors specific to
an individual investment, its issuer, or all factors affecting all instruments
traded in a market or market segment.

Commodity risk relates to the risk that the value of a commodity or commodity
index will fluctuate based on increases or decreases in the commodities market
and factors specific to a particular industry or commodity.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust VII and the Shareowners of
Pioneer Global Multisector Income Fund:
--------------------------------------------------------------------------------

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Pioneer
Global Multisector Income Fund (the "Fund") (one of the funds constituting
Pioneer Series Trust VII (the "Trust")), including the schedule of investments,
as of October 31, 2019, 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, the financial highlights for each of the three years
in the period then ended and the related notes (collectively referred to as the
"financial statements"). The financial highlights for the periods ended October
31, 2015 and October 31, 2016 were audited by another independent registered
public accounting firm whose report, dated December 23, 2016, expressed an
unqualified opinion on those financial highlights. In our opinion, the
financial statements present fairly, in all material respects, the financial
position of the Fund (one of the funds constituting Pioneer Series Trust VII)
at October 31, 2019, 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 its financial highlights for each of the three years in the period then
ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Trust's management.
Our responsibility is to express an opinion on the Fund's financial statements
based on our audits. We are a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) ("PCAOB") and are required
to be independent with respect to the Fund in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. The Trust is not required to have,
nor were we engaged to perform, an audit of the Trust's internal control over
financial reporting. As part of our audits, we are required to obtain an
understanding of internal control over financial reporting, but not for the
purpose of expressing an opinion on the effectiveness of the Trust's internal
control over financial reporting. Accordingly, we express no such opinion.

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 65



Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included
examining, on a test basis, evidence regarding the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of October 31, 2019, by correspondence with the custodian and brokers.
Our audits also included evaluating the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the financial statements. We believe that our audits provide a
reasonable basis for our opinion.

                                                           /s/ Ernst & Young LLP

We have served as the Fund's auditor since 2017.

Approval of Investment Management Agreement

Amundi Pioneer Asset Management, Inc. ("APAM") serves as the investment adviser
to Pioneer Global Multisector Income Fund (the "Fund") pursuant to an
investment management agreement between APAM and the Fund. In order for APAM to
remain the investment adviser of the Fund, the Trustees of the Fund must
determine annually whether to renew the investment management agreement for the
Fund.

The contract review process began in January 2019 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the
process. Contract review materials were provided to the Trustees in March 2019,
July 2019 and September 2019. In addition, the Trustees reviewed and discussed
the Fund's performance at regularly scheduled meetings throughout the year, and
took into account other information related to the Fund provided to the
Trustees at regularly scheduled meetings, in connection with the review of the
Fund's investment management agreement.

In March 2019, the Trustees, among other things, discussed the memorandum
provided by Fund counsel that summarized the legal standards and other
considerations that are relevant to the Trustees in their deliberations
regarding the renewal of the investment management agreement, and reviewed and
discussed the qualifications of the investment management teams for the Fund,
as well as the level of investment by the Fund's portfolio managers in the
Fund. In July 2019, the Trustees, among other things, reviewed the Fund's
management fees and total expense ratios, the financial statements of APAM and
its parent companies, profitability analyses provided by APAM, and analyses
from APAM as to possible economies of scale. The Trustees also reviewed the
profitability of the institutional business of APAM and APAM's affiliate,
Amundi Pioneer Institutional Asset Management, Inc. ("APIAM" and, together with
APAM, "Amundi Pioneer"), as compared to that of APAM's fund management
business, and considered the differences between the fees and expenses of the
Fund and the fees and expenses of APAM's and APIAM's institutional accounts, as
well as the different services provided by APAM to the Fund and by APAM and
APIAM to the institutional accounts. The Trustees further considered contract
review materials, including additional materials received in response to the
Trustees' request, in September 2019.

At a meeting held on September 17, 2019, based on their evaluation of the
information provided by APAM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment management agreement for another year. In approving
the renewal of the investment management agreement, the Trustees

68 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



considered various factors that they determined were relevant, including the
factors described below. The Trustees did not identify any single factor as the
controlling factor in determining to approve the renewal of the agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by APAM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees also reviewed APAM's investment approach
for the Fund and its research process. The Trustees considered the resources of
APAM and the personnel of APAM who provide investment management services to
the Fund. They also reviewed the amount of non-Fund assets managed by the
portfolio managers of the Fund. They considered the non-investment resources
and personnel of APAM that are involved in APAM's services to the Fund,
including APAM's compliance, risk management, and legal resources and
personnel. The Trustees noted the substantial attention and high priority given
by APAM's senior management to the Pioneer Fund complex.

The Trustees considered that APAM supervises and monitors the performance of
the Fund's service providers and provides the Fund with personnel (including
Fund officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
APAM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to APAM for the provision of
administration services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that had been provided by APAM to the Fund were
satisfactory and consistent with the terms of the investment management
agreement.

Performance of the Fund

In considering the Fund's performance, the Trustees regularly review and
discuss throughout the year data prepared by APAM and information comparing the
Fund's performance with the performance of its peer group of funds, as
classified by Morningstar, Inc. (Morningstar), and the performance of the
Fund's benchmark index. They also discuss the Fund's performance with APAM on a
regular basis. The Trustees' regular reviews and discussions were factored into
the Trustees' deliberations concerning the renewal of the investment management
agreement.

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 69



Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund
in comparison to the management fees of its peer group of funds as classified
by Morningstar and also to the expense ratios of a peer group of funds selected
on the basis of criteria determined by the Independent Trustees for this
purpose using data provided by Strategic Insight Mutual Fund Research and
Consulting, LLC (Strategic Insight), an independent third party. The peer group
comparisons referred to below are organized in quintiles. Each quintile
represents one-fifth of the peer group. In all peer group comparisons referred
to below, first quintile is most favorable to the Fund's shareowners. The
Trustees noted that they separately review and consider the impact of the
Fund's transfer agency and Fund- and APAM-paid expenses for sub-transfer agency
and intermediary arrangements, and that the results of the most recent such
review were considered in the consideration of the Fund's expense ratio.

The Trustees considered that the Fund's management fee for the most recent
fiscal year was in the fourth quintile relative to the management fees paid by
other funds in its Morningstar category for the comparable period. The Trustees
considered that the expense ratio of the Fund's Class A shares for the most
recent fiscal year was in the second quintile relative to its Strategic Insight
peer group for the comparable period. The Trustees considered that the expense
ratio of the Fund's Class Y shares for the most recent fiscal year was in the
third quintile relative to its Strategic Insight peer group for the comparable
period. The Trustees noted that APAM had agreed to waive fees and/or reimburse
expenses in order to limit the ordinary operating expenses of the Fund.

The Trustees reviewed management fees charged by APAM and APIAM to
institutional and other clients, including publicly offered European funds
sponsored by APAM's affiliates, unaffiliated U.S. registered investment
companies (in a sub-advisory capacity), and unaffiliated foreign and domestic
separate accounts. The Trustees also considered APAM's costs in providing
services to the Fund and APAM's and APIAM's costs in providing services to the
other clients and considered the differences in management fees and profit
margins for fund and non-fund services. In evaluating the fees associated with
APAM's and APIAM's client accounts, the Trustees took into account the
respective demands, resources and complexity associated with the Fund and other
client accounts. The Trustees noted that, in some instances, the fee rates for
those clients were lower than the management fee for the Fund and considered
that, under the investment management agreement with the Fund, APAM performs
additional services for the Fund that it does not provide to those other
clients or services that are broader in scope, including oversight of the
Fund's other service providers and activities related to compliance and the
extensive regulatory and tax regimes to which the Fund is subject. The Trustees
also considered the entrepreneurial risks associated with APAM's management of
the Fund.

70 Pioneer Global Multisector Income Fund | Annual Report | 10/31/19



The Trustees concluded that the management fee payable by the Fund to APAM was
reasonable in relation to the nature and quality of the services provided by
APAM.

Profitability

The Trustees considered information provided by APAM regarding the
profitability of APAM with respect to the advisory services provided by APAM to
the Fund, including the methodology used by APAM in allocating certain of its
costs to the management of the Fund. The Trustees also considered APAM's profit
margin in connection with the overall operation of the Fund. They further
reviewed the financial results, including the profit margins, realized by APAM
and APIAM from non-fund businesses. The Trustees considered APAM's profit
margins in comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
concluded that APAM's profitability with respect to the management of the Fund
was not unreasonable.

Economies of Scale

The Trustees considered APAM's views relating to economies of scale in
connection with the Pioneer Funds as fund assets grow and the extent to which
any such economies of scale are shared with the Fund and Fund shareholders. The
Trustees recognize that economies of scale are difficult to identify and
quantify, and that, among other factors that may be relevant, are the
following: fee levels, expense subsidization, investment by APAM in research
and analytical capabilities and APAM's commitment and resource allocation to
the Fund. The Trustees noted that profitability also may be an indicator of the
availability of any economies of scale, although profitability may vary for
other reasons including due to reductions in expenses. The Trustees concluded
that economies of scale, if any, were being appropriately shared with the
Fund.

Other Benefits

The Trustees considered the other benefits that APAM enjoys from its
relationship with the Fund. The Trustees considered the character and amount of
fees paid or to be paid by the Fund, other than under the investment management
agreement, for services provided by APAM and its affiliates. The Trustees
further considered the revenues and profitability of APAM's businesses other
than the Fund business. To the extent applicable, the Trustees also considered
the benefits to the Fund and to APAM and its affiliates from the use of "soft"
commission dollars generated by the Fund to pay for research and brokerage
services.

            Pioneer Global Multisector Income Fund | Annual Report | 10/31/19 71



The Trustees considered that Amundi Pioneer is the principal U.S. asset
management business of Amundi, which is one of the largest asset managers
globally. Amundi's worldwide asset management business manages over $1.6
trillion in assets (including the Pioneer Funds). The Trustees considered that
APAM's relationship with Amundi creates potential opportunities for APAM, APIAM
and Amundi that derive from APAM's relationships with the Fund, including
Amundi's ability to market the services of APAM globally. The Trustees noted
that APAM has access to additional research and portfolio management
capabilities as a result of its relationship with Amundi and Amundi's enhanced
global presence that may contribute to an increase in the resources available
to APAM. The Trustees considered that APAM and the Fund receive reciprocal
intangible benefits from the relationship, including mutual brand recognition
and, for the Fund, direct and indirect access to the resources of a large
global asset manager. The Trustees concluded that any such benefits received by
APAM as a result of its relationship with the Fund were reasonable.

Conclusion

After consideration of the factors described above as well as other factors,
the Trustees, including the Independent Trustees, concluded that the investment
management agreement for the Fund, including the fees payable thereunder, was
fair and reasonable and voted to approve the proposed renewal of the investment
management agreement.

President's Letter

Since 1928, active portfolio management based on in-depth, fundamental
research, has been the foundation of Amundi Pioneer's investment approach. We
believe an active management investment strategy is a prudent approach to
investing, especially during periods of market volatility, which can result
from any number of risk factors, including slow U.S. economic growth, rising
interest rates, and geopolitical factors. Of course, in today's global economy,
risk factors extend well beyond U.S. borders. In fact, it's not unusual for
political and economic issues on the international front to cause or contribute
to volatility in U.S. markets.

At Amundi Pioneer, each security under consideration is researched by our team
of experienced investment professionals, who communicate directly with the
management teams of those companies. At the end of this research process, if we
have conviction in a company's business model and management team, and regard
the security as a potentially solid investment opportunity, an Amundi Pioneer
portfolio manager makes an active decision to invest in that security. The
portfolio resulting from these decisions represents an expression of his or her
convictions, and strives to balance overall risk and return opportunity.

As an example, the Standard & Poor's 500 Index -- the predominant benchmark for
many U.S. Large-Cap Core Equity funds -- has 500 stocks. An Amundi Pioneer
portfolio manager chooses to invest in only those companies that he or she
believes can offer the most attractive opportunities to pursue the fund's
investment objective, thus potentially benefiting the fund's shareowners. This
process results in a portfolio that does not own all 500 stocks, but a much
narrower universe.

The same active decision to invest in a company is also applied when we decide
to sell a security, due to changing fundamentals, valuation concerns, or market
risks. We apply this active decision-making across all of our equity,
fixed-income, and global portfolios.

Today, as investors, we have many options. It is our view that active
management can serve shareholders well, not only when markets are thriving, but
also during periods of market volatility and uncertainty, thus making it a
compelling investment choice. As you consider the many choices today, we
encourage you to work with your financial advisor to develop an overall
investment plan that addresses both your short- and long-term goals, and to
implement such a plan in a disciplined manner.

We greatly appreciate the trust you have placed in us and look forward to
continuing to serve you in the future.

Portfolio Management Discussion | 10/31/19

In the following interview, Andrew Feltus discusses the market environment and
the performance of Pioneer Global High Yield Fund during the 12-month period
ended October 31, 2019. Mr. Feltus, Managing Director, Co-Director of High
Yield, and a portfolio manager at Amundi Pioneer Asset Management, Inc. (Amundi
Pioneer), is responsible for the day-to-day management of the Fund, along with
Kenneth J. Monaghan, Managing Director, Co-Director of High Yield, and a
portfolio manager at Amundi Pioneer, and Matthew Shulkin, a vice president and
a portfolio manager at Amundi Pioneer*.

Q     How did the Fund perform during the 12-month period ended October 31,
      2019?

A     Pioneer Global High Yield Fund's Class A shares returned 6.27% at net
      asset value during the 12-month period ended October 31, 2019, while the
      Fund's benchmarks, the Bloomberg Barclays Global High Yield Index (the
      Bloomberg Barclays Index) and the ICE Bank of America Merrill Lynch (BofA
      ML) U.S. High Yield Index, returned 7.77% and 8.32%, respectively. During
      the same period, the average return of the 708 mutual funds in
      Morningstar's High Yield Bond Funds category was 7.14%.

Q     Could you please describe the investment environment in the global
      high-yield market during the 12-month period ended October 31, 2019?

A     Late 2018 saw investor sentiment for riskier assets weaken based on a
      range of concerns, including U.S.-China trade tensions, softening economic
      growth overseas, Italy's budget crisis, and geopolitical uncertainty. In
      mid-December 2018, the U.S. Federal Reserve (Fed) met expectations and
      raised its short-term rate target to the 2.25% to 2.50% range, its fourth
      rate increase during calendar year 2018. The Fed also noted the potential
      for two additional rate hikes in 2019. In combination with signs of
      slowing global economic growth and yet another setback in negotiations to
      avoid a chaotic exit by the United Kingdom from the European Union
      ("Brexit"), fears that the Fed would overshoot and raise interest rates
      too much led to a spike in volatility in the market for riskier assets.

      During December 2018, the 10-year Treasury yield declined from 3.01% to
      2.69% as investors sought a "safe haven" from the market turmoil. The U.S.
      high-yield market declined by 2.2% that month, and by 4.7% for the full
      fourth quarter of 2018. Energy-related issues, in particular, were
      battered, as crude oil prices plunged over the fourth quarter due to
      concerns about a weaker demand outlook and higher-than-expected supply
      driven in part by a loosening of U.S. sanctions on Iran.

*     Mr. Shulkin became a portfolio manager on the Fund effective September 30,
      2019.

4 Pioneer Global High Yield Fund | Annual Report | 10/31/19



      Risk-oriented assets rebounded sharply in January of 2019, however, as the
      Fed pivoted from its tightening stance on monetary policy to a
      less-aggressive stance, indicating that it was leaning toward putting
      future rate increases on pause, while also announcing an early end to its
      balance-sheet reduction program.

      At the same time, weak economic data out of the euro zone and China led to
      renewed monetary accommodation from the European Central Bank and the
      People's Bank of China, to go along with the Fed's actions. Modest
      progress on trade matters, a firming in oil prices, and positive corporate
      earnings reports also helped boost investor sentiment towards the credit
      markets. While the overall pace of gains moderated and there was some
      interim market volatility, credit-sensitive assets continued to outperform
      less-risky investments as the 12-month-period progressed.

      Over the final six months of the period, the Treasury yield curve
      continued to move lower, the result of a mid-year shift to an easing of
      monetary policy by the Fed and a "flight to safety" driven by geopolitical
      headlines, including those pertaining to the U.S.-China trade dispute,
      Brexit, and a September attack on Saudi Arabian oil facilities. Against a
      backdrop of slowing economic growth and low inflation, the Fed cut
      short-term interest rates by a quarter point three times before the end of
      the period, on July 31, September 19, and October 30, bringing the
      benchmark federal funds target rate down to a range of 1.50% to 1.75% . In
      addition, the market appeared to expect two or three additional Fed
      interest-rate cuts by the middle of 2020.

      Returns in the fixed-income markets were strong overall for the full
      12-month period, with performance supported by the notable decline in
      Treasury yields and the rebound in credit-market sentiment over the first
      quarter of 2019. The 12-month period was unusual in that returns for both
      U.S. Treasuries and high-yield corporates ended up well into positive
      territory.

Q     What were the principal factors that influenced the Fund's performance
      relative to the benchmark over the 12-month period ended October 31, 2019?

A     The main detractor from the Fund's benchmark-relative performance over the
      12-month period was duration positioning, as the portfolio was underweight
      (or shorter in duration) versus the benchmark. (Duration is a measure of
      the sensitivity of the price (the value of principal) of a fixed income
      investment to a change in interest rates, expressed as a number of years.)
      The portfolio's underweight to sovereign issues in Argentina, Ecuador,
      Lebanon, and other emerging markets drove the Fund's below-benchmark
      stance with respect to duration, which hurt relative returns in a
      declining-rate environment.

                     Pioneer Global High Yield Fund | Annual Report | 10/31/19 5



      Also in the emerging markets, the Fund's exposure to mobile service
      provider Digicell detracted from benchmark-relative returns as weak
      earnings results raised concerns about the company's ability to refinance
      its maturing debt. A position in Argentina-based electrical energy
      wholesaler Stoneway Capital also constrained the Fund's relative
      performance as market participants anticipated that a new government in
      that country would implement polices to regulate energy markets.

      Another individual portfolio holding that detracted from the Fund's
      benchmark-relative performance was telecommunications firm Frontier
      Communications. The default of Frontier's peer, Windstream, after that
      company lost a court case related to a spin-off of assets, weighed on the
      entire wireline communications segment of the market, and negatively
      affected Frontier as well. In addition, Frontier has been evaluating a
      restructuring of its debt, which raised market concerns and exerted
      further downward pressure on the bond price. However, we view the current
      bond price as significantly overstating the negative case for Frontier,
      and have maintained the Fund's position.

      A modest out-of-benchmark position in leveraged bank loans was another
      detractor from the Fund's benchmark-relative results, as the loan asset
      class underperformed high yield for the 12-month period. However, we
      believe investments in bank loans and insurance-linked securities (ILS)
      can help mitigate the effect of any rise in interest rates, while also
      offering a relative lack of correlation to the performance of traditional
      fixed-income investments. ILS are sponsored by property-and-casualty
      insurers to help mitigate the risk of having to pay claims after a natural
      disaster. The Fund's cash position also detracted from relative results
      given strong high-yield market performance.

      On the positive side, security selection results generally aided the
      Fund's benchmark-relative performance over the 12-month period. Within the
      U.S. high-yield corporate bond market, selection results within energy
      more than offset the negative impact of a portfolio overweight to the
      sector, which struggled in the wake of late-2018's sharp decline in crude
      oil prices. In particular, a focus on holding the debt of lower-volatility
      midstream and refining companies within the energy sector added notably to
      the Fund's relative returns, led by an overweight to oil-and-gas
      wholesaler Global Partners. Selection results were positive within health
      care as well, highlighted by the Fund's exposure to the convertible bonds
      of The Medicines Company, a pharmaceutical firm. Our investment thesis
      that the company would eventually be acquired began to play out during the
      12-month period, with management announcing plans for a sale and

     reports of interested buyers. Portfolio exposure to housing-related
     companies, given the backdrop of declining interest rates, also benefited
     the Fund's benchmark-relative performance. In particular, two Fund holdings
     -- homebuilder Beazer Homes and mortgage servicer Freedom Mortgage --
     reported better-than-expected results supported by continued growth in the
     housing market throughout the 12-month period.

      Within emerging markets, stock selection results versus the benchmark were
      supported by the portfolio's limited exposure to Argentina, Ecuador, and
      Lebanon, even as the underweight to sovereign issues in those countries
      helped drive the Fund's duration-related underperformance. In terms of
      individual issues in the emerging markets, contributors to the Fund's
      benchmark-relative returns were highlighted by a position in Russian
      aluminum producer RUSAL, which saw its bond price rebound as the
      implementation of U.S. sanctions was cancelled in December of 2018.

      Other positive contributors to the Fund's benchmark-relative results
      during the 12-month period included an underweight to Europe, as a
      weakening euro relative to the U.S. dollar (USD) weighed on returns within
      the region. In addition, European high-yield bonds underperformed U.S.
      high yield due to low coupon rates, slowing economic growth, and volatile
      political conditions. Finally, our hedging of the Fund's exposure to
      issues denominated in the euro and British pound benefited relative
      returns for the 12-month period.

Q     Did the Fund have any investments in derivative securities during the
      12-month period ended October 31, 2019?

A     Yes, as part of our efforts to maintain an appropriate level of portfolio
      liquidity, we utilized credit-default-swap indices to achieve a portion of
      the Fund's U.S. high-yield exposure. In an environment of declining
      Treasury yields, the instruments experienced positive returns but
      detracted slightly from the Fund's results relative to the benchmark due
      to their lack of duration and corresponding interest-rate sensitivity.

      In addition, we invested the Fund in forward foreign currency contracts to
      manage currency risk in the portfolio, and those instruments were a small
      positive contributor to performance as the euro declined relative to the
      USD over the 12-month period. We also used options on currencies as
      another vehicle to hedge currency risk, and the options were another small
      positive contributor to the Fund's return.

Q     Did the Fund's distributions** to shareholders change during the 12-month
      period ended October 31, 2019?

A     The Fund's distributions remained relatively stable during the 12-month
      period, despite volatility in both Treasury yields and credit spreads.
      (Credit spreads are commonly defined as the differences in yield between
      Treasuries and other types of fixed-income securities with similar
      maturities.)

Q     What is your investment outlook?

A     Our base scenario is for slow, but steady economic growth over the next
      several quarters. Those who anticipate a near-term recession frequently
      note that economic expansions do not last forever. From our perspective,
      we are less concerned with the age of the economic expansion than with the
      potential spread of global manufacturing weakness into the broader U.S.
      economy. The length of any particular economic expansion is always
      unpredictable, and many analysts have been claiming for years that we are
      "in the 9th inning" of the current expansion. For the moment, however, the
      risks to global economic growth from an uncontrolled trade war seem to
      have receded.

      The accommodative direction of many global central banks, including the
      Fed, has lent support to the corporate credit market. Based on historical
      averages, high-yield valuations are relatively rich, and while we do not
      view current valuations as extreme, given our expectations for a continued
      low default rate and a strong technical backdrop, we have a somewhat
      cautious stance on adding credit risk to the portfolio. We see near-term
      high-yield performance as most likely to be driven by the coupon component
      of return as opposed to further spread tightening. In addition, under
      conditions of tight spreads, investor jitters over any sign of recession,
      and elevated geopolitical uncertainty, we expect to see continued
      performance dispersion among individual issuers within the high-yield
      asset class. As a result, we view security selection as having even
      greater importance in the current environment.

      In terms of positioning, in broad terms, the Fund is overweight versus the
      benchmark to the U.S. market and continues to have a conservative stance
      within high-yield corporates, with moderate exposure to floating-rate
      issues in the form of bank loans and ILS. We view high-yield valuations in
      Europe as somewhat inexpensive, but the Fund is essentially neutrally
      positioned with respect to our long-term target for the region, given
      currency risk, and

      is underweight in Europe relative to the benchmark. The Fund is also
      underweight to the emerging markets compared to the benchmark, with a
      focus on less-interest-rate-sensitive corporates relative to sovereigns.

      As always, we will utilize intensive research when picking the Fund's
      investments, with a focus on the fundamentals and risk/reward profile of
      each individual security and issuer.

Please refer to the Schedule of Investments on pages 18-39 for a full listing
of Fund securities.

All investments are subject to risk, including the possible loss of principal.
In the past several years, financial markets have experienced increased
volatility, depressed valuations, decreased liquidity and heightened
uncertainty. These conditions may continue, recur, worsen or spread.

Investments in high-yield or lower-rated securities are subject to
greater-than-average price volatility, illiquidity and possibility of default.

When interest rates rise, the prices of fixed-income securities held by the
Fund will generally fall. Conversely, when interest rates fall, the prices of
fixed-income securities held by 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.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, and economic and political
conditions.

Prepayment risk is the chance that an issuer may exercise its right to repay
its security, if falling interest rates prompt the issuer to do so. Forced to
reinvest the unanticipated proceeds at lower interest rates, the Fund would
experience a decline in income and lose the opportunity for additional price
appreciation.

The Fund may invest in mortgage-backed securities, which during times of
fluctuating interest rates may increase or decrease more than other
fixed-income securities. Mortgage-backed securities are also subject to
pre-payments.

The Fund may use derivatives, such as options, futures, inverse floating rate
obligations, swaps, and others, which can be illiquid, may disproportionately
increase losses, and have a potentially large impact on Fund performance.
Derivatives may have a leveraging effect on the Fund.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making the Fund more susceptible to
any economic, political, or regulatory developments or other risks affecting
those industries and sectors.

These risks may increase share price volatility.

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. POP
returns reflect deduction of maximum 4.50% sales charge. NAV returns would have
been lower had sales charge been reflected. 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

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 15



Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1)   ongoing costs, including management fees, distribution and/or service
      (12b-1) fees, and other Fund expenses; and

(2)   transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

(1)   Divide your account value by $1,000
      Example: an $8,600 account value (divided by) $1,000 = 8.6

(2)   Multiply the result in (1) above by the corresponding share class's number
      in the third row under the heading entitled "Expenses Paid During Period"
      to estimate the expenses you paid on your account during this period.

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


*     Expenses are equal to the Fund's annualized expense ratio of 1.25%, 1.97%,
      and 0.96% 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 partial 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.

*     The Fund was audited by an independent registered public accounting firm
      other than Ernst & Young LLP.

(a)   The per-share data presented above is based on the average shares
      outstanding for the period presented.

(b)   The amount shown for a share outstanding does not correspond with the
      aggregate loss on investments for the period due to the timing of sales
      and repurchases of shares in relation to fluctuating market values of the
      investments of the Fund.

(c)   Assumes initial investment at net asset value at the beginning of each
      period, reinvestment of all distributions, the complete redemption of the
      investment at net asset value at the end of each period and no sales
      charges. Total return would be reduced if sales charges were taken into
      account.

(d)   If the Fund had not recognized gains in the settlement of class action
      lawsuits during the year ended October 31, 2016, the total return would
      have been 7.01%.

Notes to Financial Statements | 10/31/19

1. Organization and Significant Accounting Policies

Pioneer Global High Yield Fund (the "Fund") is one of two portfolios comprising
Pioneer Series Trust VII (the "Trust"), a Delaware statutory trust. The Fund is
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is to
maximize total return through a combination of income and capital
appreciation.

The Fund offers four classes of shares designated as Class A, Class C, Class K
and Class Y shares. Class K shares had not commenced operations as of October
31, 2019. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
rates of class-specific fees and expenses, such as transfer agent and
distribution fees. Differences in class-specific fees and expenses will result
in differences in net investment income and, therefore, the payment of
different dividends from net investment income earned by each class. The
Amended and Restated Declaration of Trust of the Fund gives the Board of
Trustees the flexibility to specify either per-share voting or dollar-weighted
voting when submitting matters for shareowner approval. Under per-share voting,
each share of a class of the Fund is entitled to one vote. Under
dollar-weighted voting, a shareowner's voting power is determined not by the
number of shares owned, but by the dollar value of the shares on the record
date. Each share class has exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. There is no distribution plan for Class Y shares.

Amundi Pioneer Asset Management, Inc., an indirect, wholly owned subsidiary of
Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc., serves as the
Fund's investment adviser (the "Adviser"). Amundi Pioneer Distributor, Inc., an
affiliate of Amundi Pioneer Asset Management, Inc., serves as the Fund's
distributor (the "Distributor").

In August 2018, the Securities and Exchange Commission ("SEC") released a
Disclosure Update and Simplification Final Rule. The Final Rule amends
Regulation S-X disclosures requirements to conform them to U.S. Generally
Accepted Accounting Principles ("U.S. GAAP") for investment companies. The
Fund's financial statements were prepared in compliance with the new amendments
to Regulation S-X.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 47



The Fund is an investment company and follows investment company accounting and
reporting guidance under U.S. GAAP. U.S. GAAP requires the management of the
Fund to 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:

A.    Security Valuation

      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.

      Fixed-income securities are valued by using prices supplied by independent
      pricing services, which consider such factors as market prices, market
      events, quotations from one or more brokers, Treasury spreads, yields,
      maturities and ratings, or may use a pricing matrix or other fair value
      methods or techniques to provide an estimated value of the security or
      instrument. A pricing matrix is a means of valuing a debt security on the
      basis of current market prices for other debt securities, historical
      trading patterns in the market for fixed-income securities and/or other
      factors. Non-U.S. debt securities that are listed on an exchange will be
      valued at the bid price obtained from an independent third party pricing
      service. When independent third party pricing services are unable to
      supply prices, or when prices or market quotations are considered to be
      unreliable, the value of that security may be determined using quotations
      from one or more broker-dealers.

      Loan interests are valued in accordance with guidelines established by the
      Board of Trustees at the mean between the last available bid and asked
      prices from one or more brokers or dealers as obtained from Loan Pricing
      Corporation, an independent third party pricing service. If price
      information is not available from Loan Pricing Corporation, or if the
      price information is deemed to be unreliable, price information will be
      obtained from an alternative loan interest pricing service. If no reliable
      price quotes are available from either the primary or alternative pricing
      service, broker quotes will be solicited.

      Event-linked bonds or catastrophe bonds are valued at the bid price
      obtained from an independent third party pricing service. Other
      insurance-linked securities (including sidecars, collateralized
      reinsurance and industry loss warranties) may be valued at the bid price
      obtained from an independent

48 Pioneer Global High Yield Fund | Annual Report | 10/31/19



      pricing service, or through a third party using a pricing matrix,
      insurance industry valuation models, or other fair value methods or
      techniques to provide an estimated value of the instrument.

      Equity securities that have traded on an exchange are valued by using the
      last sale price on the principal exchange where they are traded. Equity
      securities that have not traded on the date of valuation, or securities
      for which sale prices are not available, generally are valued using the
      mean between the last bid and asked prices or, if both last bid and asked
      prices are not available, at the last quoted bid price. Last sale and bid
      and asked prices are provided by independent third party pricing services.
      In the case of equity securities not traded on an exchange, prices are
      typically determined by independent third party pricing services using a
      variety of techniques and methods.

      The value of foreign securities is translated into U.S. dollars based on
      foreign currency exchange rate quotations supplied by a third party
      pricing source. Trading in non-U.S. equity securities is substantially
      completed each day at various times prior to the close of the NYSE. The
      values of such securities used in computing the net asset value of the
      Fund's shares are determined as of such times. The Fund may use a fair
      value model developed by an independent pricing service to value non-U.S.
      equity securities.

      Options contracts are generally valued at the mean between the last bid
      and ask prices on the principal exchange where they are traded.
      Over-the-counter ("OTC") options and options on swaps ("swaptions") are
      valued using prices supplied by independent pricing services, which
      consider such factors as market prices, market events, quotations from one
      or more brokers, Treasury spreads, yields, maturities and ratings, or may
      use a pricing matrix or other fair value methods or techniques to provide
      an estimated value of the security or instrument.

      Forward foreign currency exchange contracts are valued daily using the
      foreign exchange rate or, for longer term forward contract positions, the
      spot currency rate and the forward points on a daily basis, in each case
      provided by a third party pricing service. Contracts whose forward
      settlement date falls between two quoted days are valued by interpolation.

      Swap contracts, including interest rate swaps, caps and floors (other than
      centrally cleared swap contracts), are valued at the dealer quotations
      obtained from reputable International Swap Dealers Association members.
      Centrally cleared swaps are valued at the daily settlement price provided
      by the central clearing counterparty.

      Repurchase agreements are valued at par. Cash may include overnight time
      deposits at approved financial institutions.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 49



      Securities or loan interests for which independent pricing services or
      broker-dealers are unable to supply prices or for which market prices
      and/or quotations are not readily available or are considered to be
      unreliable are valued by a fair valuation team comprised of certain
      personnel of the Adviser pursuant to procedures adopted by the Fund's
      Board of Trustees. The Adviser's fair valuation team uses fair value
      methods approved by the Valuation Committee of the Board of Trustees. The
      Adviser's fair valuation team is responsible for monitoring developments
      that may impact fair valued securities and for discussing and assessing
      fair values on an ongoing basis, and at least quarterly, with the
      Valuation Committee of the Board of Trustees.

      Inputs used when applying fair value methods to value a security may
      include credit ratings, the financial condition of the company, current
      market conditions and comparable securities. The Fund may use fair value
      methods if it is determined that a significant event has occurred after
      the close of the exchange or market on which the security trades and prior
      to the determination of the Fund's net asset value. Examples of a
      significant event might include political or economic news, corporate
      restructurings, natural disasters, terrorist activity or trading halts.
      Thus, the valuation of the Fund's securities may differ significantly from
      exchange prices, and such differences could be material.

      At October 31, 2019, six securities were valued using fair value methods
      (in addition to securities valued using prices supplied by independent
      pricing services, broker-dealers or using a third party insurance pricing
      model) representing 0.31% of net assets. The value of this fair valued
      security was $958,285.

B.    Investment Income and Transactions

      Dividend income is recorded on the ex-dividend date, except that certain
      dividends from foreign securities where the ex-dividend date may have
      passed are recorded as soon as the Fund becomes aware of the ex-dividend
      data in the exercise of reasonable diligence.

      Interest income, including interest on income-bearing cash accounts, is
      recorded on the accrual basis. Dividend and interest income are reported
      net of unrecoverable foreign taxes withheld at the applicable country
      rates and net of income accrued on defaulted securities.

      Interest and dividend income payable by delivery of additional shares is
      reclassified as PIK (payment-in-kind) income upon receipt and is included
      in interest and dividend income, respectively.

      Principal amounts of mortgage-backed securities are adjusted for monthly
      paydowns. Premiums and discounts related to certain mortgage-backed
      securities are amortized or accreted in proportion to the monthly

50 Pioneer Global High Yield Fund | Annual Report | 10/31/19



      paydowns. All discounts/premiums on purchase prices of debt securities are
      accreted/amortized for financial reporting purposes over the life of the
      respective securities, and such accretion/amortization is included in
      interest income.

      Security transactions are recorded as of trade date. Gains and losses on
      sales of investments are calculated on the identified cost method for both
      financial reporting and federal income tax purposes.

C.    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 on the Statement of
      Operations from the effects of changes in the market prices of those
      securities, but are included with the net realized and unrealized gain or
      loss on investments.

D.    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 net taxable income and net realized capital gains,
      if any, to its shareowners. Therefore, no provision for federal income
      taxes is required. As of October 31, 2019, the Fund did not accrue any
      interest or penalties with respect to uncertain tax positions, which, if
      applicable, would be recorded as an income tax expense on the Statement of
      Operations. Tax returns filed within the prior three years remain subject
      to examination by federal and state tax authorities.

      The amount and character of income and capital gain distributions to
      shareowners are determined in accordance with federal income tax rules,
      which may differ from U.S. GAAP. Distributions in excess of net investment
      income or net realized gains are temporary over distributions for
      financial statement purposes resulting from differences in the recognition
      or classification of income or distributions for financial statement and
      tax purposes. Capital accounts within the financial statements are
      adjusted for permanent book/tax differences to reflect tax character, but
      are not adjusted for temporary differences.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 51



      At October 31, 2019, the Fund was permitted to carry forward indefinitely
      $22,665,905 of short-term and $261,957,667 of long-term losses under the
      Regulated Investment Company Modernization Act of 2010 without limitation.

      The tax character of distributions paid during the years ended October 31,
      2019 and October 31, 2018, were as follows:

      attributable to the tax deferral of losses on wash sales, the
      mark-to-market of foreign currency contracts and swaps, adjustments
      relating to catastrophe bonds and swaps.

E.    Fund Shares

      The Fund records sales and repurchases of its shares as of trade date. The
      Distributor earned $5,689 in underwriting commissions on the sale of Class
      A shares during the year ended October 31, 2019.

F.    Class Allocations

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

      Distribution fees are calculated based on the average daily net asset
      value attributable to Class A and Class C shares of the Fund, respectively
      (see Note 4). Class Y shares do not pay distribution fees. All expenses
      and fees paid to the Fund's transfer agent for its services are allocated
      among the classes of shares based on the number of accounts in each class
      and the ratable allocation of related out-of-pocket expenses (see Note 3).

52 Pioneer Global High Yield Fund | Annual Report | 10/31/19



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

G.    Risks

      The value of securities held by the Fund may go up or down, sometimes
      rapidly or unpredictably, due to general market conditions, such as real
      or perceived adverse economic, political or regulatory conditions,
      inflation, changes in interest rates, lack of liquidity in the bond
      markets or adverse investor sentiment. In the past several years,
      financial markets have experienced increased volatility, depressed
      valuations, decreased liquidity and heightened uncertainty. These
      conditions may continue, recur, worsen or spread. A general rise in
      interest rates could adversely affect the price and liquidity of
      fixed-income securities and could also result in increased redemptions
      from the Fund.

      At times, the Fund's investments may represent industries or industry
      sectors that are interrelated or have common risks, making the Fund more
      susceptible to any economic, political, or regulatory developments or
      other risks affecting those industries and sectors. The Fund's investments
      in foreign markets and countries with limited developing markets may
      subject the Fund to a greater degree of risk than investments in a
      developed market. These risks include disruptive political or economic
      conditions and the imposition of adverse governmental laws or currency
      exchange restrictions.

      The Fund invests in below-investment-grade (high-yield) debt securities
      and preferred stocks. Some of these high-yield securities may be
      convertible into equity securities of the issuer. Debt securities rated
      below-investment-grade are commonly referred to as "junk bonds" and are
      considered speculative. These securities involve greater risk of loss, are
      subject to greater price volatility, and are less liquid, especially
      during periods of economic uncertainty or change, than higher rated debt
      securities.

      With the increased use of technologies such as the Internet to conduct
      business, the Fund is susceptible to operational, information security and
      related risks. While the Fund's Adviser has established business
      continuity plans in the event of, and risk management systems to prevent,
      limit or mitigate, such cyber-attacks, there are inherent limitations in
      such plans and systems, including the possibility that certain risks have
      not been identified.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 53



      Furthermore, the Fund cannot control the cybersecurity plans and systems
      put in place by service providers to the Fund such as Brown Brothers
      Harriman & Co., the Fund's custodian and accounting agent, and DST Asset
      Manager Solutions, Inc., the Fund's transfer agent. In addition, many
      beneficial owners of Fund shares hold them through accounts at
      broker-dealers, retirement platforms and other financial market
      participants over which neither the Fund nor Amundi Pioneer exercises
      control. Each of these may in turn rely on service providers to them,
      which are also subject to the risk of cyber-attacks. Cybersecurity
      failures or breaches at Amundi Pioneer or the Fund's service providers or
      intermediaries have the ability to cause disruptions and impact business
      operations, potentially resulting in financial losses, interference with
      the Fund's ability to calculate its net asset value, impediments to
      trading, the inability of Fund shareowners to effect share purchases,
      redemptions or exchanges or receive distributions, loss of or unauthorized
      access to private shareowner information and violations of applicable
      privacy and other laws, regulatory fines, penalties, reputational damage,
      or additional compliance costs. Such costs and losses may not be covered
      under any insurance. In addition, maintaining vigilance against
      cyber-attacks may involve substantial costs over time, and system
      enhancements may themselves be subject to cyber-attacks.

      The Fund's prospectus contains unaudited information regarding the Fund's
      principal risks. Please refer to that document when considering the Fund's
      principal risks.

H.    Insurance-Linked Securities ("ILS")

      The Fund invests in ILS. The Fund could lose a portion or all of the
      principal it has invested in an ILS, and the right to additional interest
      or dividend payments with respect to the security, upon the occurrence of
      one or more trigger events, as defined within the terms of an
      insurance-linked security. Trigger events, generally, are hurricanes,
      earthquakes, or other natural events of a specific size or magnitude that
      occur in a designated geographic region during a specified time period,
      and/or that involve losses or other metrics that exceed a specific amount.
      There is no way to accurately predict whether a trigger event will occur,
      and accordingly, ILS carry significant risk. The Fund is entitled to
      receive principal, and interest and/or dividend payments so long as no
      trigger event occurs of the description and magnitude specified by the
      instrument. In addition to the specified trigger events, ILS may expose
      the Fund to other risks, including but not limited to issuer (credit)
      default, adverse regulatory or jurisdictional interpretations and adverse
      tax consequences.

54 Pioneer Global High Yield Fund | Annual Report | 10/31/19



      The Fund's investments in ILS may include event-linked bonds. ILS also may
      include special purpose vehicles ("SPVs") or similar instruments
      structured to comprise a portion of a reinsurer's catastrophe-oriented
      business, known as quota share instruments (sometimes referred to as
      reinsurance sidecars), or to provide reinsurance relating to specific
      risks to insurance or reinsurance companies through a collateralized
      instrument, known as collateralized reinsurance. Structured reinsurance
      investments also may include industry loss warranties ("ILWs"). A
      traditional ILW takes the form of a bilateral reinsurance contract, but
      there are also products that take the form of derivatives, collateralized
      structures, or exchange-traded instruments.

      Where the ILS are based on the performance of underlying reinsurance
      contracts, the Fund has limited transparency into the individual
      underlying contracts, and therefore must rely upon the risk assessment and
      sound underwriting practices of the issuer. Accordingly, it may be more
      difficult for the Adviser to fully evaluate the underlying risk profile of
      the Fund's structured reinsurance investments, and therefore the Fund's
      assets are placed at greater risk of loss than if the Adviser had more
      complete information. Structured reinsurance instruments generally will be
      considered illiquid securities by the Fund. These securities may be
      difficult to purchase, sell or unwind. Illiquid securities also may be
      difficult to value. If the Fund is forced to sell an illiquid asset, the
      Fund may be forced to sell at a loss.

I.    Repurchase Agreements

      Repurchase agreements are arrangements under which the Fund purchases
      securities from a broker-dealer or a bank, called the counterparty, upon
      the agreement of the counterparty to repurchase the securities from the
      Fund at a later date, and at a specific price, which is typically higher
      than the purchase price paid by the Fund. The securities purchased serve
      as the Fund's collateral for the obligation of the counterparty to
      repurchase the securities. The value of the collateral, including accrued
      interest, is required to be equal to or in excess of the repurchase price.
      The collateral for all repurchase agreements is held in safekeeping in the
      customer-only account of the Fund's custodian or a sub-custodian of the
      Fund. The Adviser is responsible for determining that the value of the
      collateral remains at least equal to the repurchase price. In the event of
      a default by the counterparty, the Fund is entitled to sell the
      securities, but the Fund may not be able to sell them for the price at
      which they were purchased, thus causing a loss to the Fund. Additionally,
      if the counterparty becomes insolvent, there is some risk that the Fund
      will not have a right to the securities, or the immediate right to sell
      the securities.

      As of and for the year ended October 31, 2019, the Fund had no open
      repurchase agreements.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 55



J.    Purchased Options

      The Fund may purchase put and call options to seek to increase total
      return. Purchased call and put options entitle the Fund to buy and sell a
      specified number of shares or units of a particular security, currency or
      index at a specified price at a specific date or within a specific period
      of time. Upon the purchase of a call or put option, the premium paid by
      the Fund is included on the Statement of Assets and Liabilities as an
      investment. All premiums are marked-to-market daily, and any unrealized
      appreciation or depreciation is recorded on the Fund's Statement of
      Operations. As the purchaser of an index option, the Fund has the right to
      receive a cash payment equal to any depreciation in the value of the index
      below the strike price of the option (in the case of a put) or equal to
      any appreciation in the value of the index over the strike price of the
      option (in the case of a call) as of the valuation date of the option.
      Premiums paid for purchased call and put options which have expired are
      treated as realized losses on investments on the Statement of Operations.
      Upon the exercise or closing of a purchased put option, the premium is
      offset against the proceeds on the sale of the underlying security or
      financial instrument in order to determine the realized gain or loss on
      investments. Upon the exercise or closing of a purchased call option, the
      premium is added to the cost of the security or financial instrument. The
      risk associated with purchasing options is limited to the premium
      originally paid.

      The average market value of purchased options contracts open during the
      year ended October 31, 2019, was $461,336. Open purchased options at
      October 31, 2019, are listed in the Fund's Schedule of Investments.

K.    Option Writing

      The Fund may write put and covered call options to seek to increase total
      return. When an option is written, the Fund receives a premium and becomes
      obligated to purchase or sell the underlying security at a fixed price,
      upon the exercise of the option. When the Fund writes an option, an amount
      equal to the premium received by the Fund is recorded as "Written options
      outstanding" on the Statement of Assets and Liabilities and is
      subsequently adjusted to the current value of the option written. Premiums
      received from writing options that expire unexercised are treated by the
      Fund on the expiration date as realized gains from investments on the
      Statement of Operations. The difference between the premium and the amount
      paid on effecting a closing purchase transaction, including brokerage
      commissions, is also treated as a realized gain on the Statement of
      Operations, or, if the premium is less than the amount paid for the
      closing purchase transaction, as a realized loss on the Statement of
      Operations. If a call option is exercised, the premium is added to the
      proceeds from the sale of the underlying security in

56 Pioneer Global High Yield Fund | Annual Report | 10/31/19



      determining whether the Fund has realized a gain or loss. The Fund as
      writer of an option bears the market risk of an unfavorable change in the
      price of the security underlying the written option.

      The average market value of written options for the year ended October 31,
      2019, was $(43,412). Open written options contracts at October 31, 2019,
      are listed in the Fund's Schedule of Investments.

L.    Forward Foreign Currency Exchange Contracts

      The Fund may enter into forward foreign currency exchange contracts
      ("contracts") for the purchase or sale of a specific foreign currency at a
      fixed price on a future date. All contracts are marked-to-market daily at
      the applicable exchange rates, and any resulting unrealized appreciation
      or depreciation is recorded in the Fund's financial statements. The Fund
      records realized gains and losses at the time a contract is offset by
      entry into a closing transaction or extinguished by delivery of the
      currency. Risks may arise upon entering into these contracts from the
      potential inability of counterparties to meet the terms of the contract
      and from unanticipated movements in the value of foreign currencies
      relative to the U.S. dollar (see Note 7).

      At October 31, 2019, the Fund had entered into various forward foreign
      currency exchange contracts that obligated the Fund to deliver or take
      delivery of currencies at specified future maturity dates. Alternatively,
      prior to the settlement date of a forward foreign currency contract, the
      Fund may close out such contract by entering into an offsetting contract.

      The average market value of forward foreign currency exchange contracts
      open during the year ended October 31, 2019, was $(32,060). Open forward
      foreign currency exchange contracts outstanding at October 31, 2019, are
      listed in the Schedule of Investments.

M.    Credit Default Swap Contracts

      A credit default swap is a contract between a buyer of protection and a
      seller of protection against a pre-defined credit event or an underlying
      reference obligation, which may be a single security or a basket or index
      of securities. The Fund may buy or sell credit default swap contracts to
      seek to increase the Fund's income, or to attempt to hedge the risk of
      default on portfolio securities. A credit default swap index is used to
      hedge risk or take a position on a basket of credit entities or indices.

      As a seller of protection, the Fund would be required to pay the notional
      (or other agreed-upon) value of the referenced debt obligation to the
      counterparty in the event of a default by a U.S. or foreign corporate
      issuer of a debt obligation, which would likely result in a loss to the
      Fund. In return, the

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 57



      Fund would receive from the counterparty a periodic stream of payments
      during the term of the contract, provided that no event of default
      occurred. The maximum exposure of loss to the seller would be the notional
      value of the credit default swaps outstanding. If no default occurs, the
      Fund would keep the stream of payments and would have no payment
      obligation. The Fund may also buy credit default swap contracts in order
      to hedge against the risk of default of debt securities, in which case the
      Fund would function as the counterparty referenced above.

      As a buyer of protection, the Fund makes an upfront or periodic payment to
      the protection seller in exchange for the right to receive a contingent
      payment. An upfront payment made by the Fund, as the protection buyer, is
      recorded within the "Swap contracts, at value" line item on the Statement
      of Assets and Liabilities. Periodic payments received or paid by the Fund
      are recorded as realized gains or losses on the Statement of Operations.

      Credit default swap contracts are marked-to-market daily using valuations
      supplied by independent sources, and the change in value, if any, is
      recorded within the "Swap contracts, at value" line item on the Statement
      of Assets and Liabilities. Payments received or made as a result of a
      credit event or upon termination of the contract are recognized, net of
      the appropriate amount of the upfront payment, as realized gains or losses
      on the Statement of Operations.

      Credit default swap contracts involving the sale of protection may involve
      greater risks than if the Fund had invested in the referenced debt
      instrument directly. Credit default swap contracts are subject to general
      market risk, liquidity risk, counterparty risk and credit risk. If the
      Fund is a protection buyer and no credit event occurs, it will lose its
      investment. If the Fund is a protection seller and a credit event occurs,
      the value of the referenced debt instrument received by the Fund, together
      with the periodic payments received, may be less than the amount the Fund
      pays to the protection buyer, resulting in a loss to the Fund. In
      addition, obligations under sell protection credit default swaps may be
      partially offset by net amounts received from settlement of buy protection
      credit default swaps entered into by the Fund for the same reference
      obligation with the same counterparty.

      Certain swap contracts that are cleared through a central clearinghouse
      are referred to as centrally cleared swaps. All payments made or received
      by the Fund are pursuant to a centrally cleared swap contract with the
      central clearing party rather than the original counterparty. Upon
      entering into a centrally cleared swap contract, the Fund is required to
      make an initial margin deposit, either in cash or in securities. The daily
      change in value on open centrally cleared contracts is recorded as
      "Variation margin for centrally cleared swaps" on the Statement of Assets
      and Liabilities. Cash received from or paid to the broker related to
      previous margin movement is held in a

58 Pioneer Global High Yield Fund | Annual Report | 10/31/19



      segregated account at the broker and is recorded as either "Due from
      broker for swaps" or "Due to broker for swaps" on the Statement of Assets
      and Liabilities. The amount of cash deposited with a broker as collateral
      at October 31, 2019, is recorded as "Swaps collateral" on the Statement of
      Assets and Liabilities.

      The average market value of credit default swap contracts open during the
      year ended October 31, 2019, was $291,871. Open credit default swap
      contracts at October 31, 2019, are listed in the Schedule of Investments.

2. Management Agreement

The Adviser manages the Fund's portfolio. Management fees are calculated daily
at the annual rate of 0.70% of the Fund's average daily net assets up to $500
million; 0.65% of the next $500 million; 0.60% of the next $500 million; 0.55%
of the next $500 million; and 0.45% on assets over $2 billion. For the year
ended October 31, 2019, the effective management fee (excluding waivers and/or
assumption of expenses) was equivalent to 0.70% of the Fund's average daily net
assets.

Effective October 1, 2019, the Adviser has contractually agreed to limit
ordinary operating expenses (ordinary operating expenses means all fund
expenses other than extraordinary expenses, such as litigation, taxes,
brokerage commissions and acquired fund fees and expenses) of the Fund to the
extent required to reduce Fund expenses to 1.14% and 0.90% of the average daily
net assets attributable to Class A and Class Y shares, respectively. These
expense limitations are in effect through March 1, 2021 for Class A shares and
Class Y shares. Fees waived and expenses reimbursed during the year ended
October 31, 2019 are reflected on the Statement of Operations. There can be no
assurance that the Adviser will extend the expense limitation agreement for a
class of shares beyond the date referred to above.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$17,191 in management fees, administrative costs and certain other
reimbursements payable to the Adviser at October 31, 2019.

3. Transfer Agent

DST Asset Manager Solutions, Inc. serves as the transfer agent to the Fund at
negotiated rates. Transfer agent fees and payables shown on the Statement of
Operations and the Statement of Assets and Liabilities, respectively, include
sub-transfer agent expenses incurred through the Fund's omnibus relationship
contracts.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 59



In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareowner communications activities
such as proxy and statement mailings, and outgoing phone calls. For the year
ended October 31, 2019, such out-of-pocket expenses by class of shares were as
follows:


--------------------------------------------------------------------------------
Shareowner Communications
--------------------------------------------------------------------------------
                                                                     
Class A                                                                 $31,015
Class C                                                                   6,109
Class Y                                                                   5,746
--------------------------------------------------------------------------------
 Total                                                                  $42,870
================================================================================


4. Distribution and Service Plans

The Fund has adopted a distribution plan (the "Plan") pursuant to Rule 12b-1 of
the Investment Company Act of 1940 with respect to its Class A and Class C
shares. Pursuant to the Plan, the Fund pays the Distributor 0.25% of the
average daily net assets attributable to Class A shares as compensation for
personal services and/or account maintenance services or distribution services
with regard to Class A shares. Pursuant to the Plan, the Fund also pays the
Distributor 1.00% of the average daily net assets attributable to Class C
shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class C shares.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $6,133 in distribution fees payable to the Distributor at
October 31, 2019.

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 12
months of purchase. Redemptions of Class C shares within 12 months of purchase
are subject to a CDSC of 1.00%, based on the lower of cost or market value of
shares being redeemed. Shares purchased as part of an exchange remain subject
to any CDSC that applied to the original purchase of those shares. There is no
CDSC for Class Y shares. Proceeds from the CDSCs are paid to the Distributor.
For the year ended October 31, 2019, CDSCs in the amount of $1,038 were paid to
the Distributor.

5. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
"Funds"), participates in a committed, unsecured revolving line of credit
facility. Borrowings are used solely for temporary or emergency purposes. The
Fund may borrow up to the lesser of the amount available under the credit
facility or the limits set for borrowing by the Fund's prospectus and the 1940

60 Pioneer Global High Yield Fund | Annual Report | 10/31/19



Act. Effective August 1, 2018, the Fund participates in a credit facility in
the amount of $250 million. Under such facility, depending on the type of loan,
interest on borrowings is payable at the London Interbank Offered Rate
("LIBOR") plus a credit spread. The Funds also pay an annual commitment fee to
participate in a credit facility. The commitment fee is allocated among
participating Funds based on an allocation schedule set forth in the credit
agreement. For the year ended October 31, 2019, the Fund had no borrowings
under the credit facility.

6. Master Netting Agreement

The Fund has entered into an International Swaps and Derivatives Association,
Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with
substantially all of its derivative counterparties. An ISDA Master Agreement is
a bilateral agreement between the Fund and a counterparty that governs the
trading of certain Over the Counter ("OTC") derivatives and typically contains,
among other things, close-out and set-off provisions which apply upon the
occurrence of an event of default and/or a termination event as defined under
the relevant ISDA Master Agreement. The ISDA Master Agreement may also give a
party the right to terminate all transactions traded under such agreement if,
among other things, there is deterioration in the credit quality of the other
party. Upon an event of default or a termination of the ISDA Master Agreement,
the non-defaulting party has the right to close out all transactions under such
agreement and to net amounts owed under each transaction to determine one net
amount payable by one party to the other. The right to close out and net
payments across all transactions under the ISDA Master Agreement could result
in a reduction of the Fund's credit risk to its counterparty equal to any
amounts payable by the Fund under the applicable transactions, if any. However,
the Fund's right to setoff may be restricted or prohibited by the bankruptcy or
insolvency laws of the particular jurisdiction to which each specific ISDA of
each counterparty is subject.

The collateral requirements for derivatives transactions under an ISDA Master
Agreement are governed by a credit support annex to the ISDA Master Agreement.
Collateral requirements are generally determined at the close of business each
day and are typically based on changes in market values for each transaction
under an ISDA Master Agreement and netted into one amount for such agreement.
Generally, the amount of collateral due from or to a counterparty is subject to
threshold (a "minimum transfer amount") before a transfer is required, which
may vary by counterparty. Collateral pledged for the benefit of the Fund and/or
counterparty is held in segregated accounts by the Fund's custodian and cannot
be sold, re-pledged, assigned or otherwise used while pledged. Cash that has
been segregated to cover the Fund's

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 61



collateral obligations, if any, will be reported separately on the Statement of
Assets and Liabilities as "Swaps collateral". Securities pledged by the Fund as
collateral, if any, are identified as such in the Schedule of Investments.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Pioneer Series Trust VII and the Shareowners of
Pioneer Global High Yield Fund:
--------------------------------------------------------------------------------

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Pioneer
Global High Yield Fund (the "Fund") (one of the funds constituting Pioneer
Series Trust VII (the "Trust")), including the schedule of investments, as of
October 31, 2019, 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, the financial highlights for each of the three years in the
period then ended and the related notes (collectively referred to as the
"financial statements"). The financial highlights for the periods ended October
31, 2015 and October 31, 2016 were audited by another independent registered
public accounting firm whose report, dated December 23, 2016, expressed an
unqualified opinion on those financial highlights. In our opinion, the
financial statements present fairly, in all material respects, the financial
position of the Fund (one of the funds constituting Pioneer Series Trust VII)
at October 31, 2019, 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 its financial highlights for each of the three years in the period then
ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Trust's management.
Our responsibility is to express an opinion on the Fund's financial statements
based on our audits. We are a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) ("PCAOB") and are required
to be independent with respect to the Fund in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. The Trust is not required to have,
nor were we engaged to perform, an audit of the Trust's internal control over
financial reporting. As part of our audits, we are required to obtain an
understanding of internal control over financial reporting, but not for the
purpose of expressing an opinion on the effectiveness of the Trust's internal
control over financial reporting. Accordingly, we express no such opinion.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 65



Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included
examining, on a test basis, evidence regarding the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of October 31, 2019, by correspondence with the custodian and brokers.
Our audits also included evaluating the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the financial statements. We believe that our audits provide a
reasonable basis for our opinion.

                                                           /s/ Ernst & Young LLP

We have served as the Fund's auditor since 2017.

Approval of Investment Management Agreement

Amundi Pioneer Asset Management, Inc. ("APAM") serves as the investment adviser
to Pioneer Global High Yield Fund (the "Fund") pursuant to an investment
management agreement between APAM and the Fund. In order for APAM to remain the
investment adviser of the Fund, the Trustees of the Fund must determine
annually whether to renew the investment management agreement for the Fund.

The contract review process began in January 2019 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the
process. Contract review materials were provided to the Trustees in March 2019,
July 2019 and September 2019. In addition, the Trustees reviewed and discussed
the Fund's performance at regularly scheduled meetings throughout the year, and
took into account other information related to the Fund provided to the
Trustees at regularly scheduled meetings, in connection with the review of the
Fund's investment management agreement.

In March 2019, the Trustees, among other things, discussed the memorandum
provided by Fund counsel that summarized the legal standards and other
considerations that are relevant to the Trustees in their deliberations
regarding the renewal of the investment management agreement, and reviewed and
discussed the qualifications of the investment management teams for the Fund,
as well as the level of investment by the Fund's portfolio managers in the
Fund. In July 2019, the Trustees, among other things, reviewed the Fund's
management fees and total expense ratios, the financial statements of APAM and
its parent companies, profitability analyses provided by APAM, and analyses
from APAM as to possible economies of scale. The Trustees also reviewed the
profitability of the institutional business of APAM and APAM's affiliate,
Amundi Pioneer Institutional Asset Management, Inc. ("APIAM" and, together with
APAM, "Amundi Pioneer"), as compared to that of APAM's fund management
business, and considered the differences between the fees and expenses of the
Fund and the fees and expenses of APAM's and APIAM's institutional accounts, as
well as the different services provided by APAM to the Fund and by APAM and
APIAM to the institutional accounts. The Trustees further considered contract
review materials, including additional materials received in response to the
Trustees' request, in September 2019.

At a meeting held on September 17, 2019, based on their evaluation of the
information provided by APAM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment management agreement for another year. In approving
the renewal of the investment management agreement, the Trustees

68 Pioneer Global High Yield Fund | Annual Report | 10/31/19



considered various factors that they determined were relevant, including the
factors described below. The Trustees did not identify any single factor as the
controlling factor in determining to approve the renewal of the agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by APAM to the Fund, taking into account the investment objective
and strategy of the Fund. The Trustees also reviewed APAM's investment approach
for the Fund and its research process. The Trustees considered the resources of
APAM and the personnel of APAM who provide investment management services to
the Fund. They also reviewed the amount of non-Fund assets managed by the
portfolio managers of the Fund. They considered the non-investment resources
and personnel of APAM that are involved in APAM's services to the Fund,
including APAM's compliance, risk management, and legal resources and
personnel. The Trustees noted the substantial attention and high priority given
by APAM's senior management to the Pioneer Fund complex.

The Trustees considered that APAM supervises and monitors the performance of
the Fund's service providers and provides the Fund with personnel (including
Fund officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
APAM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to APAM for the provision of
administration services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that had been provided by APAM to the Fund were
satisfactory and consistent with the terms of the investment management
agreement.

Performance of the Fund

In considering the Fund's performance, the Trustees regularly review and
discuss throughout the year data prepared by APAM and information comparing the
Fund's performance with the performance of its peer group of funds, as
classified by Morningstar, Inc. (Morningstar), and the performance of the
Fund's benchmark index. They also discuss the Fund's performance with APAM on a
regular basis. The Trustees' regular reviews and discussions were factored into
the Trustees' deliberations concerning the renewal of the investment management
agreement.

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 69



Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund
in comparison to the management fees of its peer group of funds as classified
by Morningstar and also to the expense ratios of a peer group of funds selected
on the basis of criteria determined by the Independent Trustees for this
purpose using data provided by Strategic Insight Mutual Fund Research and
Consulting, LLC (Strategic Insight), an independent third party. The peer group
comparisons referred to below are organized in quintiles. Each quintile
represents one-fifth of the peer group. In all peer group comparisons referred
to below, first quintile is most favorable to the Fund's shareowners. The
Trustees noted that they separately review and consider the impact of the
Fund's transfer agency and Fund- and APAM-paid expenses for sub-transfer agency
and intermediary arrangements, and that the results of the most recent such
review were considered in the consideration of the Fund's expense ratio.

The Trustees considered that the Fund's management fee for the most recent
fiscal year was in the fourth quintile relative to the management fees paid by
other funds in its Morningstar category for the comparable period. The Trustees
considered that the expense ratio of the Fund's Class A shares for the most
recent fiscal year was in the fourth quintile relative to its Strategic Insight
peer group for the comparable period. The Trustees noted the resource
commitment necessary to manage a fund that invests significantly in non-U.S.
securities. The Trustees noted that APAM had agreed to waive fees and/or
reimburse expenses in order to limit the ordinary operating expenses of the
Fund, effective October 1, 2019.

The Trustees reviewed management fees charged by APAM and APIAM to
institutional and other clients, including publicly offered European funds
sponsored by APAM's affiliates, unaffiliated U.S. registered investment
companies (in a sub-advisory capacity), and unaffiliated foreign and domestic
separate accounts. The Trustees also considered APAM's costs in providing
services to the Fund and APAM's and APIAM's costs in providing services to the
other clients and considered the differences in management fees and profit
margins for fund and non-fund services. In evaluating the fees associated with
APAM's and APIAM's client accounts, the Trustees took into account the
respective demands, resources and complexity associated with the Fund and other
client accounts. The Trustees noted that, in some instances, the fee rates for
those clients were lower than the management fee for the Fund and considered
that, under the investment management agreement with the Fund, APAM performs
additional services for the Fund that it does not provide to those other
clients or services that are broader in scope, including oversight of

70 Pioneer Global High Yield Fund | Annual Report | 10/31/19



the Fund's other service providers and activities related to compliance and the
extensive regulatory and tax regimes to which the Fund is subject. The Trustees
also considered the entrepreneurial risks associated with APAM's management of
the Fund.

The Trustees concluded that the management fee payable by the Fund to APAM was
reasonable in relation to the nature and quality of the services provided by
APAM.

Profitability

The Trustees considered information provided by APAM regarding the
profitability of APAM with respect to the advisory services provided by APAM to
the Fund, including the methodology used by APAM in allocating certain of its
costs to the management of the Fund. The Trustees also considered APAM's profit
margin in connection with the overall operation of the Fund. They further
reviewed the financial results, including the profit margins, realized by APAM
and APIAM from non-fund businesses. The Trustees considered APAM's profit
margins in comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
concluded that APAM's profitability with respect to the management of the Fund
was not unreasonable.

Economies of Scale

The Trustees considered APAM's views relating to economies of scale in
connection with the Pioneer Funds as fund assets grow and the extent to which
any such economies of scale are shared with the Fund and Fund shareholders. The
Trustees recognize that economies of scale are difficult to identify and
quantify, and that, among other factors that may be relevant, are the
following: fee levels, expense subsidization, investment by APAM in research
and analytical capabilities and APAM's commitment and resource allocation to
the Fund. The Trustees noted that profitability also may be an indicator of the
availability of any economies of scale, although profitability may vary for
other reasons including due to reductions in expenses. The Trustees concluded
that economies of scale, if any, were being appropriately shared with the
Fund.

Other Benefits

The Trustees considered the other benefits that APAM enjoys from its
relationship with the Fund. The Trustees considered the character and amount of
fees paid or to be paid by the Fund, other than under the investment management
agreement, for services provided by APAM and its affiliates. The

                    Pioneer Global High Yield Fund | Annual Report | 10/31/19 71



Trustees further considered the revenues and profitability of APAM's businesses
other than the Fund business. To the extent applicable, the Trustees also
considered the benefits to the Fund and to APAM and its affiliates from the use
of "soft" commission dollars generated by the Fund to pay for research and
brokerage services.

The Trustees considered that Amundi Pioneer is the principal U.S. asset
management business of Amundi, which is one of the largest asset managers
globally. Amundi's worldwide asset management business manages over $1.6
trillion in assets (including the Pioneer Funds). The Trustees considered that
APAM's relationship with Amundi creates potential opportunities for APAM, APIAM
and Amundi that derive from APAM's relationships with the Fund, including
Amundi's ability to market the services of APAM globally. The Trustees noted
that APAM has access to additional research and portfolio management
capabilities as a result of its relationship with Amundi and Amundi's enhanced
global presence that may contribute to an increase in the resources available
to APAM. The Trustees considered that APAM and the Fund receive reciprocal
intangible benefits from the relationship, including mutual brand recognition
and, for the Fund, direct and indirect access to the resources of a large
global asset manager. The Trustees concluded that any such benefits received by
APAM as a result of its relationship with the Fund were reasonable.

Conclusion

After consideration of the factors described above as well as other factors,
the Trustees, including the Independent Trustees, concluded that the investment
management agreement for the Fund, including the fees payable thereunder, was
fair and reasonable and voted to approve the proposed renewal of the investment
management agreement.

 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 Amudi Pioneer Asset Management, Inc, 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.
