October was a particularly poor month for both U.S. and global equity markets, as every major stock market index finished the month in negative territory. Results have been more mixed on the fixed-income side, with rising interest rates pushing down most year-to-date returns. On the economic front, U.S. gross domestic product (GDP) growth exceeded 4% in the second quarter of 2018 and topped 3% once again in the third quarter. The low unemployment rate has continued, with initial jobless claims recently hitting a multi-decade low and consumer and small-business confidence also achieving levels not seen in many years. Despite the good economic news, and even though wages have been rising, inflation expectations have not risen significantly. For its part, the U.S. Federal Reserve System (the Fed) has continued with its tightening of monetary policy by raising interest rates three times in 2018, while moving forward with the tapering of its balance sheet, a process which began in October 2017. The greater market volatility this year as compared to last year has been driven by several factors. The aforementioned rising interest rates have been one reason, while the uncertainty surrounding U.S. trade policy has, at times, also led to unsettled markets. Of course, in today's global economy, risk factors extend well beyond U.S. borders, and in recent months investors have grappled with various issues on the international front, including questions surrounding the United Kingdom's Brexit negotiations, concerns about the budgetary policies of the populist Italian government, and the potential impact of Turkey's economic challenges on European banks. Moreover, while trade tensions between the U.S. and Europe have moderated, questions about the future of the U.S./China trade relationship remain unresolved, and any major fracture in that relationship could have a negative impact on China's economy and, by extension, on its Asian trade partners. With regard to our market outlook, over the medium term, we believe the fundamental investment case for U.S. equities remains in place, with support from the fairly positive economic backdrop and with an additional lift potentially coming from the investment side as U.S. businesses consider increasing capital expenditures. We do believe market volatility will persist and, therefore, careful selection of investment themes, sector allocations, and individual stocks will be increasingly relevant to overall performance, as the 2 Pioneer Global High Yield Fund | Annual Report | 10/31/18 maturity of the economic and market cycles could eventually become headwinds. We believe a focus on owning shares of quality companies trading at reasonable prices is key to navigating the current equity-market phase. In fixed income, we have taken a more cautious approach across our core portfolios with regard to credit-sensitive debt such as corporate bonds, favoring quality and liquidity. As interest rates have risen, we find that short- and intermediate-term U.S. Treasuries have become more attractive, and that agency mortgage-backed securities (MBS) and high-quality, non-agency MBS now also offer lower downside risk. In general, we think structured sectors (such as asset-backed securities and MBS) are more attractive than corporate sectors. We believe this year's market fluctuations as well as increased risk factors within the global economy have served to remind investors of the importance of active management. Since 1928, active management has been the foundation of Amundi Pioneer's investment approach. We believe active management is especially important during periods of volatility, and that our shareowners can benefit from the experience and tenure of our investment teams, who work collaboratively to make active and informed decisions across our funds. As always, and particularly during times of market uncertainty, 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. Sincerely, /s/ Lisa M. Jones Lisa M.

Pioneer Global High Yield Fund | Annual Report | 10/31/18 3 Portfolio Management Discussion | 10/31/18 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, 2018. Mr. Feltus, Managing Director, Co-Director of High Yield, and a portfolio manager at Amundi Pioneer Asset Management, Inc. ("Amundi Pioneer") is lead manager of the Fund, which is co-managed by Kenneth J. Monaghan, Managing Director, Co-Director of High Yield, and a portfolio manager at Amundi Pioneer. Q How did the Fund perform during the 12-month period ended October 31, 2018? A Pioneer Global High Yield Fund's Class A shares returned -1.78% at net asset value during the 12-month period ended October 31, 2018, 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 -1.92% and 0.86%, respectively. During the same period, the average return of the 697 mutual funds in Morningstar's High Yield Bond Funds category was 0.45%. Q Could you please describe the market environment for global high-yield investors during the 12-month period ended October 31, 2018? A The interest-rate environment provided a headwind for bond investors in general over the period. With inflation approaching its 2% target, the U.S. Federal Reserve (the Fed) implemented four incremental hikes in its benchmark overnight lending rate over the 12 months, increasing the upper target range for the federal funds rate to 2.25%. U.S. Treasury yields rose across the curve for the period. Entering the period, credit-oriented areas of the bond market - or securities susceptible to default risk rather than interest-rate risk - continued to receive support from positive global economic data. The U.S. economy posted gross domestic product (GDP) growth in the 3% range over the final three quarters of 2017, against a backdrop of robust corporate earnings and arguably full employment. The economies of Europe and Japan were comfortably in positive territory over that same period as well, while China continued to report growth in the 7% range. Credit-market sentiment received an additional boost as 2017 drew to a close with the passage of a U.S. tax package that included a lowering of the corporate tax rate and a window during which companies were permitted to accelerate the expensing of capital investments. 4 Pioneer Global High Yield Fund | Annual Report | 10/31/18 While risk-oriented markets opened 2018 with a positive tenor, volatility would soon come to the forefront. In January, U.S. employment data surprised to the upside, leading the market to revise inflation expectations higher while also raising concerns that the Fed would accelerate the pace of its expected rate hikes. While sentiment about inflation stabilized fairly quickly, the markets received another jolt in March as the Trump administration announced its intention to impose tariffs on steel and aluminum as well as a wide range of imports from China. The announcement raised the prospect of a trade war - with the potential to undermine global economic growth - even as leading indicators in Europe suggested that the rate of growth had peaked. The Trump administration's escalating trade rhetoric and continued threats of tariffs on a range of products from various global trading partners would lead to bouts of market volatility over the remainder of the period. April 2018 saw Treasury yields embark on another upward swing in the wake of the release of the Fed's March meeting minutes, which pointed toward a consensus among committee members that U.S. inflation was safely headed toward its target and that there was perhaps room to raise the federal funds rate more rapidly than previously expected. The ongoing climb in crude oil prices, which broke through the $50-per-barrel trading range in late 2017, fueled additional anxiety about inflation and interest rates among investors, while also promising to largely offset the benefit to consumers from lower individual U.S. tax rates. The firming outlook for higher U.S. interest rates led to a significant weakening in the bonds and currencies of some of the less fundamentally sound emerging markets issuers, with Turkey and Argentina feeling the most significant effects. The euro also declined meaningfully versus the U.S. dollar (USD) during the period, as slowing regional economic growth (in contrast to accelerating growth in the United States) prompted the European Central Bank (ECB) to maintain its zero-interest-rate policy and put its potential tightening cycle on hold into 2019. Prices of U.S. high-yield securities were supported over the 12-month period by a continued low default rate relative to historical averages. In addition, notably lower new-issue supply relative to the same period a year earlier helped pricing and served as a counterweight against the negative effects of outflows from high-yield mutual funds. Within the high-yield market, lower-rated issues outperformed higher-rated credits over the 12 months. As the period drew to a close in October, however, U.S. high-yield bonds came under pressure alongside the sharpest one-month decline for the Standard & Poor's 500 Index since September 2011. Investor sentiment for riskier assets in October had to contend with an underwhelming start to the Pioneer Global High Yield Fund | Annual Report | 10/31/18 5 third-quarter corporate earnings season, especially with respect to technology companies; further deterioration in U.S.-China trade relations; softening economic growth overseas; Italy's budget crisis; and geopolitical uncertainty. Q What were the principal factors that influenced the Fund's benchmark- relative performance during the 12-month period ended October 31, 2018? A A cautious stance in the portfolio with respect to the emerging markets aided the Fund's returns relative to the Bloomberg Barclays Index during the period. As the emerging markets asset class struggled during April and May on concerns about rising Treasury yields and USD strength, we further trimmed the Fund's emerging markets exposure, rather than increasing it due to the weakness. In particular, we reduced portfolio exposure to non- USD-denominated debt. The move proved to be beneficial for the Fund's relative returns as emerging markets currencies headed lower and performance for the asset class continued to weaken. In addition, the Fund's underweighting of sovereign issues relative to corporates within the emerging markets helped relative performance, as sovereign prices were more negatively affected by rising interest rates. With regard to country allocation, the Fund's limited exposure to Turkey, which experienced a currency crisis, and its overweight to Brazil, which elected a president viewed as pro-growth, helped benchmark-relative returns. In terms of currency allocations, the portfolio's tactically long exposure to the Egyptian pound proved beneficial for benchmark-relative results. While the Fund's emerging markets positioning was a positive contributor to overall benchmark-relative performance, a portfolio position in the debt of Russian aluminum producer RUSAL was among the larger individual detractors from relative returns over the 12 months, as the threat of U.S. sanctions against Russia weighed heavily on the bond price. We continue to view RUSAL as a relatively defensive holding, given the company's strong competitive position, low debt, and cash-rich balance sheet, and so we have maintained the Fund's position. In fact, the bond price has recovered much of the lost ground, as the implementation of sanctions has been delayed several times. With that said, the situation remains unresolved. Another positive contributor to the Fund's benchmark-relative results during the period was a portfolio underweight to Europe, as a weakening euro relative to the USD weighed on returns for that market. In addition, European high-yield bonds underperformed U.S. high yield, due to low coupons, slowing economic growth, and the volatile political situation in Italy. Despite the outperformance of the portfolio's underweight to Europe, 6 Pioneer Global High Yield Fund | Annual Report | 10/31/18 however, two of the biggest individual detractors from the Fund's benchmark-relative returns during the period were positions in German value-fashion retailer Takko, and Greece-based gaming company Intralot. In the U.S., as credit spreads have tightened and the high-yield segment has outperformed in recent years, we have moved the Fund's portfolio to a more conservative stance in the high-yield corporate market, underweighting more speculative bonds in the "CCC" quality range. (Credit spreads are commonly defined as the differences in yield between Treasuries and other types of fixed-income securities with similar maturities). The move to a more conservative U.S. corporate stance proved to be a constraint on the Fund's benchmark-relative performance over the 12-month period, as lower-rated U.S. high-yield issues outperformed against a backdrop of low default rates. With regard to individual high-yield issues in the portfolio, Bausch HealthCare (formerly known as Valeant Pharmaceuticals) was a leading positive contributor to the Fund's relative returns for the period. Bausch's bond prices improved as the company began to take steps to reduce its debt, while moving to what we believe is a more sustainable business model. Exposure to U.S. wireline companies also aided the Fund's relative performance. In particular, a position in Frontier Communications, a leading consolidator of legacy landline services, contributed positively. A position in Windstream Holdings was another outperformer for the Fund, although to a lesser degree, due to uncertainty concerning an investor law suit seeking to reverse the spin-off of Windstream's network assets into a separate publicly-traded real estate investment trust (REIT). We expect Windstream to be successful in defending the suit, however, and so we have maintained the Fund's position. The Fund's overweighting of global energy-related issues benefited benchmark-relative performance during the 12 months, as the segment was bolstered by the strength in crude oil prices seen over much of the period. In that vein, the Fund's exposure to Canadian oil sands firm MEG Energy contributed positively to relative returns. The bond price rose when MEG was the subject of a buyout offer, which was rejected. On the other hand, a Fund position in Argentina's state-controlled energy company YPF acted as a drag on relative returns, as the peso plunged and spread-widening for the country's sovereign debt had a negative effect on that market. Finally, modest out-of-benchmark portfolio positions in leveraged bank loans and insurance-linked securities (ILS), including so-called "cat bonds," made positive contributions to the Fund's benchmark-relative performance. ILS are issued by insurers seeking to mitigate the cost of post-disaster Pioneer Global High Yield Fund | Annual Report | 10/31/18 7 claims payouts. We like the floating-rate features of both bank loans and ILS in a rising-rate environment, as well as their relative lack of correlation with traditional fixed-income instruments. Q Did the Fund have any investments in derivative securities during the 12-month period ended October 31, 2018? A Yes, we invested in some credit-default swaps to manage the portfolio's exposure to the high-yield corporate sector during periods of asset flows into or out of the Fund. The swaps had a slight positive influence on the Fund's results. Currency forwards used to manage currency risk in the portfolio were a small positive contributor as well, as the euro declined relative to the USD over the 12-month period. We also used options on currencies to hedge currency risk in the portfolio, which was another slightly positive performance contributor. Q Did the Fund's distributions* to shareholders change during the 12-month period ended October 31, 2018? A The Fund's distributions declined during the 12-month period as high-yield bonds outperformed other sectors and credit spreads compressed. Essentially, as high-yield bond prices rose, their yields declined. In addition, newer portfolio holdings usually paid lower yields than older debt that had been issued when market rates were higher. Q What is your investment outlook? A We have been somewhat cautious with respect to U.S. high-yield corporates, although the reversal seen as the Fund's annual reporting period drew to a close has served to improve the relative value of the market segment. The yields on offer are attractive, and we find the fundamental outlook constructive given our baseline scenario of continued U.S. economic strength over the next few quarters. In addition, the composition of the high-yield market is healthy, with most issuance in the "BB" range and limited issuance in support of leveraged buyouts. At the same time, market volatility is expected to increase as the Fed continues to normalize its benchmark federal funds rate. European high-yield valuations appear to be at about average levels relative to their U.S. counterparts. The quality profile of the European market is somewhat higher than for U.S. high yield, but weakness in the euro and slow economic growth in the region has weighed on investor sentiment. If, as expected, the ECB feels it has room to raise rates in 2019, that would help support the euro and improve the attractiveness of European bonds. While * Distributions are not guaranteed. 8 Pioneer Global High Yield Fund | Annual Report | 10/31/18 the emerging markets have been battered recently, we view valuations as having essentially returned to being in-line with historical averages, and have maintained the Fund's underweight to that market segment, given the risks associated with higher U.S. interest rates and USD strength. In broad terms, the portfolio is overweight the U.S. market, while we have maintained a conservative stance within high-yield corporates and moderate exposure to floating-rate issues in the form of bank loans and ILS. Conversely, the Fund is slightly underweight to Europe and meaningfully underweight the emerging markets, with a focus on corporates that are less interest-rate sensitive relative to sovereigns within the latter segment. We continue to take a measured approach when it comes to adding credit risk to the portfolio. In addition, we are maintaining a meaningfully below- benchmark duration in order to position the Fund to take advantage of any rise in market interest rates, or a widening of credit spreads that results in valuation opportunities. (Duration is 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.) Please refer to the Schedule of Investments on pages 18-42 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 in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities in the Fund will generally rise. Investments in the Fund are subject to possible loss due to the financial failure of issuers of underlying securities and their inability to meet their debt obligations. 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. Pioneer Global High Yield Fund | Annual Report | 10/31/18 9 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 it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility. Before investing, consider the product's investment objectives, risks, charges and expenses.

Pioneer Global High Yield Fund | Annual Report | 10/31/18 15 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Global High Yield Fund Based on actual returns from May 1, 2018, through October 31, 2018. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 5/1/18 -------------------------------------------------------------------------------- Ending Account Value (after expenses) $1,027.73 $ 977.96 $ 983.25 on 10/31/18 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.98 $ 9.47 $ 4.60 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.17%, 1.90%, and 0.92% multiplied by the average account value over the period, multiplied by 184/365 (to reflect the partial year period). 16 Pioneer Global High Yield Fund | Annual Report | 10/31/18 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Global High Yield Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from May 1, 2018, through October 31, 2018. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 5/1/18 -------------------------------------------------------------------------------- Ending Account Value (after expenses) $1,019.31 $1,015.63 $1,020.57 on 10/31/18 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.96 $ 9.65 $ 4.69 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.17%, 1.90%, and 0.92% multiplied by the average account value over the period, multiplied by 184/365 (to reflect the partial year period).

The accompanying notes are an integral part of these financial statements. Pioneer Global High Yield Fund | Annual Report | 10/31/18 49 Notes to Financial Statements | 10/31/18 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 five classes of shares designated as Class A, Class C, Class K, Class T and Class Y shares. Class K and Class T had not commenced operations as of October 31, 2018. Class Z shares converted to Class Y shares as of the close of business on August 7, 2015. 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 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 50 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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. Pioneer Global High Yield Fund | Annual Report | 10/31/18 51 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. Repurchase agreements are valued at par. Cash may include overnight time deposits at approved financial institutions. 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. 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 52 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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, 2018, 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 0.37% of net assets. The value of these fair valued securities was $1,347,761. 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 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. Pioneer Global High Yield Fund | Annual Report | 10/31/18 53 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, 2018, 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. At October 31, 2018, the Fund reclassified $26,318,950 to decrease distributable earnings (loss) and $26,318,950 to decrease paid-in capital to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. 54 Pioneer Global High Yield Fund | Annual Report | 10/31/18 At October 31, 2018, the Fund was permitted to carry forward $23,803,431 of short-term capital losses and $245,593,154 of long-term capital losses without limitation. Since unlimited losses are required to be used first, loss carryforwards that are subject to expiration may be more likely to expire unused. The amount of capital loss carryforward that expired unused in 2018 was $26,270,910. The tax character of distributions paid during the years ended October 31, 2018 and October 31, 2017, were as follows: --------------------------------------------------------------------------- 2018 2017 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $26,397,633 $29,779,606 Tax return of capital -- 3,237,618 --------------------------------------------------------------------------- Total $26,397,633 $33,017,224 =========================================================================== The following shows the components of distributable earnings on a federal income tax basis at October 31, 2018: --------------------------------------------------------------------------- 2018 --------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $(269,396,585) Dividend payable (195,768) Net unrealized depreciation (33,879,510) --------------------------------------------------------------------------- Total $(303,471,863) =========================================================================== 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 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 $7,155 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2018. 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). Pioneer Global High Yield Fund | Annual Report | 10/31/18 55 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. 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 countries with emerging (or 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. Interest rates in the U.S. have been historically low and have begun to rise, so the Fund faces a heightened risk that interest rates may continue to rise. 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. 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 56 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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 shareowners 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 event-linked bonds and other ILS. The Fund could lose a portion or all of the principal it has invested in an ILS, and the right to additional interest 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 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. Pioneer Global High Yield Fund | Annual Report | 10/31/18 57 The Fund's investments in ILS 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. 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 58 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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. Open repurchase agreements as of October 31, 2018 are disclosed in the Fund's Schedule of Investments. 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, 2018 was $192,825. Open purchased options at October 31, 2018 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 Pioneer Global High Yield Fund | Annual Report | 10/31/18 59 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, 2018 was $(81,201). Open written options contracts at October 31, 2018 are listed in the Fund's Schedule of Investments. L. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts ("contracts") for the purchase or sale of a specific foreign currency at a fixed price on a future date. 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, 2018, the Fund had entered into various forward foreign currency 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 contracts open during the year ended October 31, 2018 was $(13,502,153). Forward foreign currency contracts outstanding at October 31, 2018 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 60 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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 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. Pioneer Global High Yield Fund | Annual Report | 10/31/18 61 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, 2018, 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, 2018 was $515,061. Open credit default swap contracts at October 31, 2018 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, 2018, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.70% of the Fund's average daily net assets. 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 $35,090 in management fees, administrative costs and certain other reimbursements payable to the Adviser at October 31, 2018. 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. 62 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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, 2018, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareowner Communications -------------------------------------------------------------------------------- Class A $28,434 Class C 12,740 Class Y 17,129 -------------------------------------------------------------------------------- Total $58,303 ================================================================================ 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 $14,341 in distribution fees payable to the Distributor at October 31, 2018. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge ("CDSC"). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 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, 2018, CDSCs in the amount of $2,306 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 Pioneer Global High Yield Fund | Annual Report | 10/31/18 63 facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. Prior to August 1, 2018 the credit facility was in the amount of $195 million. Effective August 1, 2018, the Fund participates in a credit facility that is in the amount of $250 million. Under such credit facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate ("LIBOR") plus 0.90% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date, or (c) 2% plus the overnight Eurodollar rate on the borrowing date. The Funds 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, 2018, 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 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 64 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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 "Forwards collateral" and/or "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 not been offset on the Statement of Assets and Liabilities. The following charts show gross assets and liabilities of the Fund as of October 31, 2018. ------------------------------------------------------------------------------------------------------- Derivative Assets Derivatives Non-Cash Cash Net Amount Subject to Master Available for Collateral Collateral of Derivative Counterparty Netting Agreement Offset Received (a) Received (a) Assets (b) ------------------------------------------------------------------------------------------------------- Bank of America NA $622,001 $(49,246) $ -- $ -- $572,755 JPMorgan Chase Bank NA 28,669 -- -- -- 28,669 Goldman Sachs International 318,196 (6,517) -- -- 311,679 State Street Bank & Trust Co. 28,299 (28,299) -- -- -- ------------------------------------------------------------------------------------------------------- Total $997,165 $(84,062) $ -- $ -- $913,103 ======================================================================================================= ------------------------------------------------------------------------------------------------------- Derivative Liabilities Derivatives Non-Cash Cash Net Amount Subject to Master Available for Collateral Collateral of Derivative Counterparty Netting Agreement Offset Pledged (a) Pledged (a) Liabilities (c) ------------------------------------------------------------------------------------------------------- Bank of America NA $ 49,246 $(49,246) $ -- $ -- $ -- Citibank NA 6,857 -- -- -- 6,857 Goldman Sachs International 6,517 (6,517) -- -- -- State Street Bank & Trust Co. 79,213 (28,299) -- -- 50,914 ------------------------------------------------------------------------------------------------------- Total $141,833 $(84,062) $ -- $ -- $ 57,771 ======================================================================================================= (a) The amount presented here may be less than the total amount of collateral received/pledged as the net amount of derivative assets and liabilities cannot be less than $0.

Pioneer Global High Yield Fund | Annual Report | 10/31/18 65 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. The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at October 31, 2018 was as follows: --------------------------------------------------------------------------------- Foreign Statement of Interest Credit Exchange Equity Commodity Assets and Liabilities Rate Risk Risk Rate Risk Risk Risk --------------------------------------------------------------------------------- Assets Currency put options purchased* $ -- $ -- $622,001 $ -- $ -- Swap contracts, at value -- 584,808 -- -- -- --------------------------------------------------------------------------------- Total Value $ -- $ 584,808 $622,001 $ -- $ -- ================================================================================= Liabilities Written options outstanding $ -- $ -- $ 49,246 $ -- $ -- Net unrealized depreciation on forward foreign currency contracts -- -- 35,619 -- -- --------------------------------------------------------------------------------- Total Value $ -- $ -- $ 84,865 $ -- $ -- ================================================================================= * Reflects the market value of purchased option contracts (see Note 1J.).

Pioneer Global High Yield Fund | Annual Report | 10/31/18 67 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust VII and the Shareholders of Pioneer Global High Yield Fund: -------------------------------------------------------------------------------- Opinion on the Financial Statements We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Global High Yield Fund (the "Fund") (one of the funds constituting Pioneer Series Trust VII (the "Trust")) as of October 31, 2018, and the related statements of operations, changes in net assets and the financial highlights for the year then ended and the related notes, and the statement of changes in net assets and financial highlights for the year ended October 31, 2017 (collectively referred to as the "financial statements"). The financial highlights for periods ended October 31, 2014, 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 at October 31, 2018, the results of its operations, the changes in its net assets, and the financial highlights for the year ended, and the statement of changes in net assets and financial highlights for the year ended October 31, 2017, in conformity with U.S. generally accepted accounting principles. Basis for Opinion These financial statements are the responsibility of the Fund'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 Fund is not required to have, nor were we engaged to perform, an audit of the Fund'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 Fund's internal control over financial reporting. Accordingly, we express no such opinion. 68 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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, 2018, 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. Boston, Massachusetts December 21, 2018 Pioneer Global High Yield Fund | Annual Report | 10/31/18 69 Additional Information (unaudited) Qualified interest income is exempt from nonresident alien (NRA) tax withholding. The percentage of the Fund's ordinary income distributions derived from qualified interest income was 48.47%. Change in Independent Registered Public Accounting Firm Prior to July 3, 2017 Pioneer Investment Management, Inc. (the "Adviser"), the Fund's investment adviser, was an indirect, wholly owned subsidiary of UniCredit S.p.A. ("UniCredit"). On that date, UniCredit completed the sale of its Pioneer Investments business, which includes the Adviser, to Amundi (the "Transaction"). As a result of the Transaction, the Adviser became an indirect, wholly owned subsidiary of Amundi. Amundi is controlled by Credit Agricole S.A. Amundi is headquartered in Paris, France, and, as of September 30, 2016, had more than $1.1 trillion in assets under management worldwide. Deloitte & Touche LLP ("D&T"), the Fund's previous independent registered public accounting firm, informed the Audit Committee and the Board that it would no longer be independent with respect to the Fund upon the completion of the Transaction as a result of certain services being provided to Amundi and Credit Agricole, and, accordingly, that it intended to resign as the Fund's independent registered public accounting firm upon the completion of the Transaction. D&T's resignation was effective on July 3, 2017, when the Transaction was completed. During the periods as to which D&T has served as the Fund's independent registered public accounting firm, D&T's reports on the Fund's financial statements have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles. Further, there have been no disagreements with D&T on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of D&T, would have caused D&T to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934. Effective immediately following the completion of the Transaction on July 3, 2017, the Board, acting upon the recommendation of the Audit Committee, engaged an independent registered public accounting firm, Ernst & Young LLP ("EY"). 70 Pioneer Global High Yield Fund | Annual Report | 10/31/18 Prior to its engagement, EY had advised the Fund's Audit Committee that EY had identified the following matters, in each case relating to services rendered by other member firms of Ernst & Young Global Limited, all of which are located outside the United States, to UniCredit and certain of its subsidiaries during the period commencing July 1, 2016, that it determined to be inconsistent with the auditor independence rules set forth by the Securities and Exchange Commission ("SEC"): (a) project management support services to UniCredit in the Czech Republic, Germany, Italy, Serbia and Slovenia in relation to twenty-two projects, that were determined to be inconsistent with Rule 2-01(c)(4)(vi) of Regulation S-X (management functions); (b) two engagements for UniCredit in Italy where fees were contingent/success based and that were determined to be inconsistent with Rule 2-01(c)(5) of Regulation S-X (contingent fees); (c) four engagements where legal and expert services were provided to UniCredit in the Czech Republic and Germany, and twenty engagements where the legal advisory services were provided to UniCredit in Austria, Czech Republic, Italy and Poland, that were determined to be inconsistent with Rule 2-01(c)(4)(ix) and (x) of Regulation S-X (legal and expert services); and (d) two engagements for UniCredit in Italy involving assistance in the sale of certain assets, that were determined to be inconsistent with Rule 2-01(c)(4)(viii) of Regulation S-X (broker-dealer, investment adviser or investment banking services). None of the foregoing services involved the Fund, any of the other funds in the Pioneer Family of Funds or any other Pioneer entity sold by UniCredit in the Transaction. EY advised the Audit Committee that it had considered the matters described above and had concluded that such matters would not impair EY's ability to exercise objective and impartial judgment in connection with the audits of the financial statements of the Fund under the SEC and Public Company Accounting Oversight Board independence rules, and that a reasonable investor with knowledge of all relevant facts and circumstances would reach the same conclusion. Management and the Audit Committee considered these matters and discussed the matters with EY and, based upon EY's description of the matters and statements made by EY, Management and the Audit Committee believe that EY will be capable of exercising objective and impartial judgment in connection with the audits of the financial statements of the Fund, and Management further believes that a reasonable investor with knowledge of all relevant facts and circumstances would reach the same conclusion. Pioneer Global High Yield Fund | Annual Report | 10/31/18 71 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 2018 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 2018, July 2018 and September 2018. 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 2018, 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 2018, 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 2018. At a meeting held on September 18, 2018, 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 72 Pioneer Global High Yield Fund | Annual Report | 10/31/18 approving the renewal of the investment management agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the 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 | 10/31/18 73 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 also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. 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 considered that the expense ratio of the Fund's Class Y 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 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 74 Pioneer Global High Yield Fund | Annual Report | 10/31/18 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 noted the breakpoints in the management fee schedule. 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 Pioneer Global High Yield Fund | Annual Report | 10/31/18 75 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 $1.7 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. 76 Pioneer Global High Yield Fund | Annual Report | 10/31/18 Trustees, Officers and Service Providers Investment Adviser Amundi Pioneer Asset Management, Inc.

October was a particularly poor month for both U.S. and global equity markets, as every major stock market index finished the month in negative territory. Results have been more mixed on the fixed-income side, with rising interest rates pushing down most year-to-date returns. On the economic front, U.S. gross domestic product (GDP) growth exceeded 4% in the second quarter of 2018 and topped 3% once again in the third quarter. The low unemployment rate has continued, with initial jobless claims recently hitting a multi-decade low and consumer and small-business confidence also achieving levels not seen in many years. Despite the good economic news, and even though wages have been rising, inflation expectations have not risen significantly. For its part, the U.S. Federal Reserve System (the Fed) has continued with its tightening of monetary policy by raising interest rates three times in 2018, while moving forward with the tapering of its balance sheet, a process which began in October 2017. The greater market volatility this year as compared to last year has been driven by several factors. The aforementioned rising interest rates have been one reason, while the uncertainty surrounding U.S. trade policy has, at times, also led to unsettled markets. Of course, in today's global economy, risk factors extend well beyond U.S. borders, and in recent months investors have grappled with various issues on the international front, including questions surrounding the United Kingdom's Brexit negotiations, concerns about the budgetary policies of the populist Italian government, and the potential impact of Turkey's economic challenges on European banks. Moreover, while trade tensions between the U.S. and Europe have moderated, questions about the future of the U.S./China trade relationship remain unresolved, and any major fracture in that relationship could have a negative impact on China's economy and, by extension, on its Asian trade partners. With regard to our market outlook, over the medium term, we believe the fundamental investment case for U.S. equities remains in place, with support from the fairly positive economic backdrop and with an additional lift potentially coming from the investment side as U.S. businesses consider increasing capital expenditures. We do believe market volatility will persist and, therefore, careful selection of investment themes, sector allocations, and individual stocks will be increasingly relevant to overall performance, as the 2 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 maturity of the economic and market cycles could eventually become headwinds. We believe a focus on owning shares of quality companies trading at reasonable prices is key to navigating the current equity-market phase. In fixed income, we have taken a more cautious approach across our core portfolios with regard to credit-sensitive debt such as corporate bonds, favoring quality and liquidity. As interest rates have risen, we find that short- and intermediate-term U.S. Treasuries have become more attractive, and that agency mortgage-backed securities (MBS) and high-quality, non-agency MBS now also offer lower downside risk. In general, we think structured sectors (such as asset-backed securities and MBS) are more attractive than corporate sectors. We believe this year's market fluctuations as well as increased risk factors within the global economy have served to remind investors of the importance of active management. Since 1928, active management has been the foundation of Amundi Pioneer's investment approach. We believe active management is especially important during periods of volatility, and that our shareowners can benefit from the experience and tenure of our investment teams, who work collaboratively to make active and informed decisions across our funds. As always, and particularly during times of market uncertainty, 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. Sincerely, /s/ Lisa M. Jones Lisa M.

Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 3 Portfolio Management Discussion | 10/31/18 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, 2018. Mr. Feltus, 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, a senior vice president, and a portfolio manager at Amundi Pioneer, and Bradley R. 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, 2018? A Pioneer Global Multisector Income Fund's Class A shares returned -4.41% at net asset value during the 12-month period ended October 31, 2018, while the Fund's benchmark, the Bloomberg Barclays Global Aggregate Bond Index (the Bloomberg Barclays Index), returned -2.05%. During the same period, the average return of the 310 mutual funds in Morningstar's World Bond Funds category was -1.91%. Q How would you describe the investment environment for fixed-income securities during the 12-month period ended October 31, 2018? A Fixed-income markets experienced a number of headwinds over the past year, leading to a negative return for the Fund's benchmark, the Bloomberg Barclays Index. The U.S. economy picked up steam, with 4.2% gross domestic product (GDP) growth in the second quarter and estimates calling for GDP growth in excess of 3% for 2018 as a whole. Accelerating growth prompted the U.S. Federal Reserve (the Fed) to continue tightening monetary policy. The Fed raised interest rates by a quarter point on three separate occasions between January and September 2018, bringing the total number of rate hikes to eight since it began moving off of its zero-interest-rate policy in late 2015. In addition, the Fed continued to withdraw liquidity from the markets by moving forward with the reduction of its balance sheet, a process that began in October 2017. Those developments weighed heavily on the interest-rate-sensitive segments of the domestic bond market during the period, as U.S. Treasury yields surged, Treasury prices fell, and both corporate bonds and securitized assets posted negative returns. Emerging markets bonds, which * Mr. Komenda became a portfolio manager of the Fund effective June 8, 2018. 4 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 experienced the additional challenges of political and economic turmoil in a number of larger countries within the emerging markets category, produced particularly weak performance during the 12-month period. However, high-yield bonds and senior bank loans performed reasonably well when compared with investment-grade issues. High-yield securities benefited from improving economic growth and the concurrent improvement in the default outlook, while the floating-rate feature of bank loans attracted hearty investor demand. The strength of the U.S. economy represented a contrast to the developed international markets, which generally continued to experience sluggish growth. The divergence, together with the Fed's more aggressive approach to tightening monetary policy compared with the actions of other global central banks, resulted in robust gains for the U.S. dollar (USD) versus most major foreign currencies. 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, 2018? A The Fund's currency positioning played the largest role in its benchmark- relative underperformance during the period. We entered the period with long portfolio positions against the USD in the euro, Japanese yen, Swedish krona, and Norwegian krone, which was consistent with the stronger economic growth we were seeing in the overseas economies at that time. That aspect of our investment strategy initially helped the Fund's performance, as the USD did in fact decline versus other currencies in the initial months of the period. Signs of slower-than-expected economic growth overseas in early February touched off a rally in the USD, however, causing the Fund's currency positioning to begin working against benchmark-relative returns. Although we subsequently reduced the extent of the portfolio's long positions in developed-market currencies, we did not act soon enough to avoid the performance downturn. The Fund's benchmark-relative returns were also negatively affected by exposure to emerging markets currencies, which were particularly hard hit by rising U.S. rates and worries about the impact a possible trade war could have on global economic growth. As was the case with the Fund's developed-market positions, we reduced the portfolio's long currency exposures in that area. While the decision limited the impact of further weakness in emerging currencies, the previous sell-off was enough to cost the Fund some benchmark-relative performance. Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 5 On the plus side, the Fund's relative returns benefited from our decisions regarding portfolio duration. (Duration is 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.) We kept the Fund's duration shorter than that of the Bloomberg Barclays Index throughout the fiscal year, in response to the backdrop of accelerating domestic economic growth as well as rising interest rates. The decision contributed positively to the Fund's relative performance by insulating the portfolio from the full effect of rising yields. Later in the period, we moved the Fund's duration closer to a neutral positioning versus the benchmark, based on the belief that market expectations had caught up to our view regarding the Fed's tighter monetary policy. Asset allocation decisions were another positive contributor to the Fund's benchmark-relative returns during the period. We maintained an emphasis on the credit-sensitive sectors - or sectors more sensitive to default risk than interest-rate risk - and an underweight to interest-rate-sensitive government bonds within the developed markets. That proved to be the correct portfolio positioning during a time in which economic strength was the key theme driving market performance. In addition, a portfolio allocation to bank loans, which attracted robust investor demand due to their floating-rate feature, posted a positive return and aided the Fund's benchmark-relative performance. However, the Fund's allocation to emerging markets debt detracted from relative returns. Q Did the Fund invest in any derivative securities? If so, did the derivatives have a material impact on benchmark-relative performance during the 12-month period ended October 31, 2018? A We invested the Fund in three types of derivatives during the period: forward foreign currency transactions (currency forwards), U.S. Treasury futures, and credit default swaps. We invested in the currency forwards to help manage portfolio risk with regard to changes in relative currency values. The currency forwards had a modest, negative effect on relative performance. We invested in the Treasury futures to help manage interest- rate risk. The Treasury futures helped the Fund's benchmark-relative performance significantly, as the Fund's short-duration stance contributed to returns during a period that saw Treasury yields rise. Finally, the Fund had only a very small exposure to credit default swaps, which had a slightly positive impact on relative results. 6 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 Q Were there any changes in the Fund's distributions** to shareholders during the 12-month period ended October 31, 2018? A The Fund's distributions to shareholders rose in comparison to the same period one year ago, due to an increase in yields across the fixed-income markets. Q How was the Fund positioned as of period-end, and does the positioning reflect your broader outlook? A The Fund's overall positioning reflects our view that the backdrop of healthy economic growth, higher inflation, and tighter Fed monetary policy is likely to remain in place, as is the possibility of increased market volatility. In that vein, we have maintained a selective investment approach designed to manage portfolio risk and to capitalize on potential values as they emerge. We have continued to look for opportunities in asset categories that provide portfolio diversification*** and that may demonstrate lower sensitivity to rising interest rates. The Fund's position in bank loans reflects that focus, since loans have tended to perform well when rates are rising. We also have maintained an allocation to insurance-linked securities (ILS), including so-called "catastrophe bonds," based on their attractive yields and low correlation to other market segments. However, we have reduced the Fund's ILS weighting, somewhat, in response to richer valuations in that segment of the market. We view Treasury Inflation-Protected Securities (TIPS) as another potential source of portfolio diversification, in that they may help offset rising inflation -- a development that would likely have a negative effect on rate-sensitive assets. In addition, we have continued to emphasize investments in the credit- sensitive sectors over investments in government issues. We see little opportunity for upside in U.S. Treasuries or in the low-yielding sovereign bonds of Japan and the euro bloc. Conversely, we are maintaining an overweight portfolio position in emerging markets bonds. While risk has risen for the emerging markets as a whole, select economies have been benefiting from stronger global economic growth and increased demand in their domestic markets. The recent sell-off in the emerging markets has created more attractive valuations in the category, which we believe represents a potential investment opportunity. With that said, we have reduced the Fund's allocations to specific emerging markets countries that appear more vulnerable to broader macroeconomic concerns, including Argentina, Brazil, Indonesia, and India. ** Distributions are not guaranteed. *** Diversification does not assure a profit nor protect against loss. Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 7 With regard to currencies, the Fund ended the 12-month period with a smaller-than-normal position in the emerging markets, in response to the backdrop of tighter global financial conditions. At period-end, the portfolio also had an overweight in the Japanese yen in an attempt to capitalize on that currency's historic tendency to benefit from "flights to quality" during times of increased volatility in the world financial markets. On the domestic side, we were active in managing the Fund's weighting in high-yield bonds during the 12-month period. In the early part of the period, we reduced the size of the Fund's high-yield position in order to moderate overall portfolio risk and to lighten the weighting in an area where we thought yield spreads had moved to unattractive levels. (Credit, or yield spreads, are commonly defined as the differences in yield between Treasuries and other types of fixed-income securities with similar maturities.) Later in the Fund's fiscal year, however, we began to build back the high-yield position in order to capitalize on the category's more compelling valuations. The Fund was overweight in high yield at the close of the 12-month period. We also have retained portfolio allocations to both investment-grade corporates and securitized assets (such as mortgage-backed securities and asset-backed securities), with a selective approach in both areas. Within corporates, the Fund is overweight in financials and in the mid-stream energy sector, as we believe those areas of the market offer better downside protection against event risk. In total, we believe the investment strategies outlined here may better position the Fund to take advantage of the wide range of opportunities and risk factors often observed across the global fixed-income markets. Please refer to the Schedule of Investments on pages 17-45 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 in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed income securities in the Fund will generally rise. 8 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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 fluctu- ating 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. These risks may increase share price volatility. Before investing, consider the product's investment objectives, risks, charges and expenses.

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, 2019, 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 a more current expense ratio. 14 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Global Multisector Income Fund Based on actual returns from May 1, 2018, through October 31, 2018. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 5/1/18 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) $ 957.91 $ 954.01 $ 959.59 on 10/31/18 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 4.94 $ 8.91 $ 3.70 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.00%, 1.81%, and 0.75% 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 one-half year period). Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 15 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Global Multisector Income Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from May 1, 2018, through October 31, 2018. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 5/1/18 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) $1,020.16 $1,016.08 $1,021.42 on 10/31/18 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.09 $ 9.20 $ 3.82 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.00%, 1.81%, and 0.75% 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 one-half year period). 16 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 Schedule of Investments | 10/31/18 ----------------------------------------------------------------------------------------------------- Shares Value ----------------------------------------------------------------------------------------------------- UNAFFILIATED ISSUERS -- 98.8% CONVERTIBLE PREFERRED STOCKS -- 1.2% of Net Assets BANKS -- 1.2% Diversified Banks -- 1.2% 229(a) Bank of America Corp., 7.25% $ 291,128 220(a) Wells Fargo & Co., 7.5% 279,838 ------------ Total Banks $ 570,966 ----------------------------------------------------------------------------------------------------- TOTAL CONVERTIBLE PREFERRED STOCKS (Cost $565,411) $ 570,966 ----------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------- Principal Amount USD ($) ----------------------------------------------------------------------------------------------------- ASSET BACKED SECURITIES -- 0.4% of Net Assets BANKS -- 0.4% Thrifts & Mortgage Finance -- 0.4% 70,000 Hardee's Funding LLC, Series 2018-1A, Class A2II, 4.959%, 6/20/48 (144A) $ 69,531 100,000 Progress Residential Trust, Series 2017-SFR1, Class E, 4.261%, 8/17/34 (144A) 98,074 39,459(b) RCO Mortgage LLC, Series 2017-1, Class A1, 3.375%, 8/25/22 (144A) 39,199 201(b) Structured Asset Securities Corp., Series 2004-19XS, Class A6B, 5.005%, 10/25/34 206 4,733(b) Terwin Mortgage Trust, Series 2005-16HE, Class AF2, 4.761%, 9/25/36 4,731 ------------ Total Banks $ 211,741 ----------------------------------------------------------------------------------------------------- TOTAL ASSET BACKED SECURITIES (Cost $214,294) $ 211,741 ----------------------------------------------------------------------------------------------------- COLLATERALIZED MORTGAGE OBLIGATIONS -- 6.7% of Net Assets BANKS -- 6.0% Thrifts & Mortgage Finance -- 6.0% 47,309(c) Agate Bay Mortgage Trust, Series 2015-1, Class A13, 3.5%, 1/25/45 (144A) $ 45,645 490(d) Alternative Loan Trust, Series 2003-14T1, Class A9, 2.731% (1 Month USD LIBOR + 45 bps), 8/25/18 322 100,000(d) Arbor Realty Commercial Real Estate Notes, Ltd., Series 2017-FL1, Class B, 4.78% (1 Month USD LIBOR + 250 bps), 4/15/27 (144A) 102,250 100,000(d) BAMLL Commercial Mortgage Securities Trust, Series 2014-FL1, Class B, 4.358% (1 Month USD LIBOR + 220 bps), 12/15/31 (144A) 100,142 80,000 BANK, Series 2017-BNK5, Class AS, 3.624%, 6/15/60 77,561 50,000(c) BANK, Series 2017-BNK8, Class B, 3.931%, 11/15/50 48,814 59,223(b)(e) Bayview Commercial Asset Trust, Series 2007-2A, Class IO, 7/25/37 (144A) -- The accompanying notes are an integral part of these financial statements.

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 five classes of shares designated as Class A, Class C, Class K, Class T and Class Y shares. Class K and Class T shares had not commenced operations as of October 31, 2018. 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 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 reported amounts of assets and liabilities, the disclosure of contingent assets Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 53 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. 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. 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. 54 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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. 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. 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. Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 55 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, 2018, no securities were valued using fair value methods (other than securities valued using prices supplied by independent pricing services, broker-dealers or using a third party insurance industry pricing model). 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 paydowns. 56 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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, 2018, 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 Multisector Income Fund | Annual Report | 10/31/18 57 At October 31, 2018, the Fund reclassified $550,079 to decrease distributions in excess of earnings and $550,079 to decrease paid-in capital to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. The tax character of distributions paid during the years ended October 31, 2018 and October 31, 2017, were as follows: --------------------------------------------------------------------------------- 2018 2017 --------------------------------------------------------------------------------- Distributions paid from: Ordinary income $ -- $ 881,209 Distribution in excess 229,211 -- Long-term capital gain -- 146,172 Return of capital 1,140,144 176,102 --------------------------------------------------------------------------------- Total $ 1,369,355 $ 1,203,483 ================================================================================= The following shows the components of distributable earnings on a federal income tax basis at October 31, 2018: --------------------------------------------------------------------------------- 2018 --------------------------------------------------------------------------------- Distributable earnings: Current year dividend payable $ (43,968) Unrealized depreciation (2,241,426) --------------------------------------------------------------------------------- Total $ (2,285,394) ================================================================================= The difference between book-basis and tax-basis net unrealized depreciation is attributable to the adjustments related to sidecars, the mark-to-market of forward, swaps and futures contracts, and interest accruals on preferred stock. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. The Distributor earned $790 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2018. 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). 58 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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. 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. Interest rates in the U.S. have been historically low and have begun to rise, so the Fund faces a heightened risk that interest rates may continue to rise. 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. 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 | 10/31/18 59 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 shareowners 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 event-linked and other ILS. The Fund could lose a portion or all of the principal it has invested in an ILS, and the right to additional interest 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 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. 60 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 The Fund's investments in ILS 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, 2018 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 | 10/31/18 61 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, 2018 was $17,728. Open purchased options at October 31, 2018 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, 2018 was $(7,438). Open written options contracts at October 31, 2018 are listed in the Fund's Schedule of Investments. K. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts ("contracts") for the purchase or sale of a specific foreign currency at a fixed price on a future date. 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 6). 62 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 At October 31, 2018, the Fund had entered into various forward foreign currency 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 contracts open during the year ended October 31, 2018, was $6,822,987. Forward foreign currency contracts outstanding at October 31, 2018, 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, 2018, 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 contracts open during the year ended October 31, 2018, was $(4,889,991). Open futures contracts outstanding at October 31, 2018 are listed in the Schedule of Investments. Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 63 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 64 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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 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, 2018, 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, 2018 was $20,122. Open credit default swap contracts at October 31, 2018 are listed in the Schedule of Investments. 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 of the Fund's average daily net assets over $1 billion. Prior to August 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, 2018, the effective management fee was equivalent to 0.47% of the Fund's average daily net assets. 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 | 10/31/18 65 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. Fees waived and expenses reimbursed during the year ended October 31, 2018, are reflected on the Statement of Operations. These expense limitations are in effect through March 1, 2019. 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 $8,377 in management fees, administrative costs and certain other reimbursements payable to the Adviser at October 31, 2018. 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, 2018, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareowner Communications: -------------------------------------------------------------------------------- Class A $ 3,785 Class C 1,659 Class Y 1,496 -------------------------------------------------------------------------------- Total $ 6,940 ================================================================================ 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 66 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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 $1,862 in distribution fees payable to the Distributor at October 31, 2018. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 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, 2018, CDSCs in the amount of $9,382 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 facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. The Fund participates in a credit facility that is in the amount of $250 million. Under such credit facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate ("LIBOR") plus 0.90% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date, or (c) 2% plus the overnight Eurodollar rate on the borrowing date. The Funds 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, 2018, the Fund had no borrowings under the credit facility. Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 67 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 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 collateral obligations, if any, will be reported separately on the Statement of Assets and Liabilities as "Swaps collateral".

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.

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.

Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 71 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust VII and the Shareholders of Pioneer Global Multisector Income Fund: -------------------------------------------------------------------------------- Opinion on the Financial Statements We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Global Multisector Income Fund (the "Fund") (one of the funds constituting the Pioneer Series Trust VII (the "Trust")) as of October 31, 2018, and the related statements of operations, changes in net assets and the financial highlights for the year then ended and the related notes, and the statement of changes in net assets and financial highlights for the year ended October 31, 2017 (collectively referred to as the "financial statements"). The financial highlights for periods ended October 31, 2014, 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 at October 31, 2018, the results of its operations, the changes in its net assets, and the financial highlights for the year ended, and the statement of changes in net assets and financial highlights for the year ended October 31, 2017, in conformity with U.S. generally accepted accounting principles. Basis for Opinion These financial statements are the responsibility of the Fund'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 Fund is not required to have, nor were we engaged to perform, an audit of the Fund'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 Fund's internal control over financial reporting. Accordingly, we express no such opinion. 72 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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, 2018, 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. Boston, Massachusetts December 21, 2018 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 73 ADDITIONAL INFORMATION Change in Independent Registered Public Accounting Firm Prior to July 3, 2017 Pioneer Investment Management, Inc. (the "Adviser"), the Fund's investment adviser, was an indirect, wholly owned subsidiary of UniCredit S.p.A. ("UniCredit"). On that date, UniCredit completed the sale of its Pioneer Investments business, which includes the Adviser, to Amundi (the "Transaction"). As a result of the Transaction, the Adviser became an indirect, wholly owned subsidiary of Amundi. Amundi is controlled by Credit Agricole S.A. Amundi is headquartered in Paris, France, and, as of September 30, 2016, had more than $1.1 trillion in assets under management worldwide. Deloitte & Touche LLP ("D&T"), the Fund's previous independent registered public accounting firm, informed the Audit Committee and the Board that it would no longer be independent with respect to the Fund upon the completion of the Transaction as a result of certain services being provided to Amundi and Credit Agricole, and, accordingly, that it intended to resign as the Fund's independent registered public accounting firm upon the completion of the Transaction. D&T's resignation was effective on July 3, 2017, when the Transaction was completed. During the periods as to which D&T has served as the Fund's independent registered public accounting firm, D&T's reports on the Fund's financial statements have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles. Further, there have been no disagreements with D&T on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of D&T, would have caused D&T to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934. Effective immediately following the completion of the Transaction on July 3, 2017, the Board, acting upon the recommendation of the Audit Committee, engaged an independent registered public accounting firm, Ernst & Young LLP ("EY"). 74 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 Prior to its engagement, EY had advised the Fund's Audit Committee that EY had identified the following matters, in each case relating to services rendered by other member firms of Ernst & Young Global Limited, all of which are located outside the United States, to UniCredit and certain of its subsidiaries during the period commencing July 1, 2016, that it determined to be inconsistent with the auditor independence rules set forth by the Securities and Exchange Commission ("SEC"): (a) project management support services to UniCredit in the Czech Republic, Germany, Italy, Serbia and Slovenia in relation to twenty-two projects, that were determined to be inconsistent with Rule 2-01(c)(4)(vi) of Regulation S-X (management functions); (b) two engagements for UniCredit in Italy where fees were contingent/success based and that were determined to be inconsistent with Rule 2-01(c)(5) of Regulation S-X (contingent fees); (c) four engagements where legal and expert services were provided to UniCredit in the Czech Republic and Germany, and twenty engagements where the legal advisory services were provided to UniCredit in Austria, Czech Republic, Italy and Poland, that were determined to be inconsistent with Rule 2-01(c)(4)(ix) and (x) of Regulation S-X (legal and expert services); and (d) two engagements for UniCredit in Italy involving assistance in the sale of certain assets, that were determined to be inconsistent with Rule 2-01(c)(4)(viii) of Regulation S-X (broker-dealer, investment adviser or investment banking services). None of the foregoing services involved the Fund, any of the other funds in the Pioneer Family of Funds or any other Pioneer entity sold by UniCredit in the Transaction. EY advised the Audit Committee that it had considered the matters described above and had concluded that such matters would not impair EY's ability to exercise objective and impartial judgment in connection with the audits of the financial statements of the Fund under the SEC and Public Company Accounting Oversight Board independence rules, and that a reasonable investor with knowledge of all relevant facts and circumstances would reach the same conclusion. Management and the Audit Committee considered these matters and discussed the matters with EY and, based upon EY's description of the matters and statements made by EY, Management and the Audit Committee believe that EY will be capable of exercising objective and impartial judgment in connection with the audits of the financial statements of the Fund, and Management further believes that a reasonable investor with knowledge of all relevant facts and circumstances would reach the same conclusion. Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 75 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 2018 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 2018, July 2018 and September 2018. 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 2018, 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 2018, 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 2018. At a meeting held on September 18, 2018, 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 76 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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 | 10/31/18 77 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 third 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 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. 78 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 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 | 10/31/18 79 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 $1.7 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. 80 Pioneer Global Multisector Income Fund | Annual Report | 10/31/18 Trustees, Officers and Service Providers Investment Adviser Amundi Pioneer Asset Management, Inc.

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.
