U.S. stocks, as measured by the Standard & Poor's 500 Index, had returned 14.23% from January 1, 2017, through September 30, 2017. Fixed-income markets, while not generating the same dazzling returns as equities, held their own, led by high-yield securities, which produced a return of 7.05% in the U.S., as measured by the ICE Bank of America Merrill Lynch U.S. High Yield Index. Meanwhile, the Bloomberg Barclays U.S. Aggregate Bond Index returned 3.14% for the first three quarters of calendar year 2017. Continued strong employment numbers and higher consumer confidence, together with solid global economic growth and a depreciating U.S. dollar contributed to better-than-expected U.S. gross domestic product (GDP) growth of more than 3% in both the second and third quarters of 2017. Outside the U.S., economic growth also surprised to the upside across the Euro zone, China, and Japan. Meanwhile, despite higher oil and commodities prices, inflation continued to be moderate, both in the U.S. and globally, enabling major non-U.S. central banks to maintain their easy monetary policies. As expected, however, the U.S. Federal Reserve System (the Fed) began tapering its balance sheet in October. The Fed also appears primed to raise interest rates a few more times in 2018, as it continues to withdraw monetary stimulus. As we transition into 2018, we believe the U.S. economy will experience modest growth in the short term, depending on the mix of economic policies enacted as the country moves away from monetary stimulus (driven by the Fed) and toward fiscal stimulus (including tax reform) as well as lighter regulatory burdens. Meanwhile, corporate earnings remain solid and we think they will improve even further, despite the possibility of some pressure from wage increases. In addition, it is our view that the economy will continue to grow and that we may begin to see a modest upturn in inflation. In that scenario, we anticipate that the Fed will continue to raise interest rates. While economic and market conditions appear solid, there are always risks to consider that could dampen the outlook. Geopolitical concerns, such as increased tensions with North Korea, and continued political gridlock in Washington are just some of the risks that could lead to increased market volatility. 2 Pioneer International Equity Fund | Annual Report | 11/30/17 It is for those reasons that we at Amundi Pioneer continue to believe that investors can benefit from the experience and tenure of our investment teams who make active and informed decisions across our funds.

Pioneer International Equity Fund | Annual Report | 11/30/17 3 Portfolio Management Discussion | 11/30/17 In the follow interview, Madelynn Matlock discusses the market environment for international equities and the factors that influenced the performance of Pioneer International Equity Fund during the 12-month period ended November 30, 2017. Ms. Matlock, a senior vice president and a portfolio manager at Amundi Pioneer Asset Management, Inc. (Amundi Pioneer), and Marco Pirondini, Executive Vice President, Head of Equities, U.S., and a portfolio manager at Amundi Pioneer, are responsible for the day-to-day management of the Fund. Q How did the Fund perform during the 12-month period ended November 30, 2017? A Pioneer International Equity Fund's Class A shares returned 28.24% at net asset value during the 12-month period ended November 30, 2017, while the Fund's benchmark, the Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) ND Index (the MSCI EAFE Index)(1), returned 27.27%. During the same period, the average return for the 432 mutual funds in Lipper's International Multi-Cap Core Funds category was 26.53%, and the average return of the 754 mutual funds in Morningstar's Foreign Large Blend Funds category was 25.95%. Q How would you characterize the investment environment for international equities during the 12-month period ended November 30, 2017? A With the help of continued monetary support from foreign central banks and a reflationary bias in the global economy, international equities enjoyed strong performance during the past 12 months. The market-friendly election outcomes in France and the Netherlands added to investor confidence in European equities. In fact, despite the uncertainty over the United Kingdom's (U.K.) potential "Brexit" from the European Union (E.U.) in the wake of the U.K. government's triggering of the Article 50 E.U. treaty withdrawal provision in March 2017, the lack of a sustained economic recovery in Japan, and the risk of more protectionist U.S. trade policies, the Fund's benchmark, the MSCI EAFE Index, outperformed U.S. stocks by a (1) The MSCI information may only be used for your internal use, may not be reproduced or re-disseminated in any form and may not be used as a basis for or a component of any financial instruments or products or indices.

The MSCI EAFE Index returned 27.27% for the period, while the Standard & Poor's 500 Index, a broad measure of the U.S. stock market, returned 22.86%. From a regional perspective, both developing and developed markets rallied during the period, led by the emerging markets, Europe, and Japan, which returned 33%, 30%, and 24%, respectively. From a sector perspective, information technology, materials, and industrials, which were up by 44%, 32%, and 31%, respectively, were the strongest performers within the Fund's benchmark. Meanwhile, real estate, while posting a very solid 19% return for the 12 months, still lagged the overall market in what was a very positive period for equities in general. Q Which of your investment strategies or individual portfolio holdings contributed to the Fund's benchmark-relative performance results during the 12-month period ended November 30, 2017? A Stock selection in information technology was advantageous for the Fund's benchmark-relative returns during the period, especially in the semiconductor industry. Within semiconductors, the portfolio's position in Tokyo Electron was a key contributor to the Fund's relative performance. Tokyo Electron is one of the most respected manufacturers of equipment used for the production of semiconductor chips, and the company saw strong demand for its products over the 12-month period. Chips are increasingly finding their way into new products and applications, from light bulbs and cars to industrial equipment. That trend is likely to continue for the foreseeable future, and we believe Tokyo Electron is in a favorable position to continue benefiting from heightened chip demand. Another strong contributor to the Fund's benchmark-relative performance during the period was a position in Yaskawa. The Japanese-based company saw rising profits based on its ability to deliver high-quality industrial robots and fully integrated robotic automation systems that empower customers to compete globally. From a regional perspective, our decision to overweight the Fund to investments in Europe augmented relative performance, as did stock selection results in that region. The Fund's position in the U.K. homebuilder Persimmon was a strong contributor to benchmark-relative returns during the period, as the company's stock price climbed in response to robust customer demand and strong profit announcements. Finally, while the Fund's exposure to the emerging markets was limited, the portfolio's investments in Taiwan-based Accton and Samsung Electronics in South Korea aided relative performance. Pioneer International Equity Fund | Annual Report | 11/30/17 5 Q Which of your investment strategies or individual portfolio holdings detracted from the Fund's benchmark-relative performance during the 12-month period ended November 30, 2017? A The Fund's investments in oil-and-gas equipment services company Schlumberger struggled during the period due to the oversupply of oil and the potential for reduced demand given the continued development of alternative energy sources. With management's forward guidance suggesting that the current supply/demand imbalance may affect Schlumberger's earnings in the second half of 2017 and into 2018, we sold the portfolio's position during the first half of the 12-month period. A position in Shire, a U.K. biotechnology company, also detracted from the Fund's performance, primarily because of concerns about the company's position in some of its important product markets. With several potential catalysts failing to propel the stock higher, we sold the portfolio's position in the second half of the period and reallocated the proceeds into other investments that we believe have stronger growth prospects. The Fund's investment in BAE Systems was another drag on benchmark-relative performance during the period. This British defense-and-aeronautics company appeared to be on track to receive several large orders, but the orders never materialized. However, we continue to hold the stock in the portfolio, as we expect defense spending - which has bottomed within the context of typical 7- to 10-year historical cycles - to rise in the coming years. We believe developed countries are likely to spend more on defense due to an increasingly uncertain geopolitical backdrop and the potential for less support from the United States. Q Did you make any noteworthy shifts in the Fund's strategy or allocations during the 12-month period ended November 30, 2017? A We did not make any notable shifts in the Fund's geographic and sector allocations, but we did trim some individual stock positions that had experienced significant price appreciation. Those decisions resulted in some reduction in the portfolio's allocation to Japan at the country level, and to basic materials at the sector level. We are continually tweaking the Fund's holdings from a portfolio- construction vantage, sizing individual positions at the security, industry, and sector level in an effort to help maximize returns and limit risk. As of November 30, 2017, the Fund had overweight exposures relative to the MSCI EAFE Index in information technology and industrials, and underweights to financials and health care. 6 Pioneer International Equity Fund | Annual Report | 11/30/17 Q Did the Fund have any derivative exposure during the 12-month period ended November 30, 2017? A No, we did not invest the Fund in derivative securities during the period. Q What is your outlook for international equities as we head into a new calendar year, and how are you positioning the Fund? A We believe central-bank policies will continue to exert a meaningful influence on the markets in 2018. In the United States, where the economy is well into its recovery, the Federal Reserve has begun tightening monetary policy by gradually raising its benchmark short-term interest rate and reducing its balance sheet, which grew substantially through its three quantitative-easing programs from 2008-2014. In international markets, where economies are improving but still lag the U.S., the details and timetables of monetary policy changes at the bellwether European Central Bank and the Bank of Japan will have broad implications for economic growth as their outlooks shift from accommodation to tightening over the next couple of years. In this environment, we believe international equities could trend higher in 2018 due to a global economic expansion and the potential for fiscal stimulus initiatives, such as tax reform in the U.S. In such a reflationary environment, we believe cyclical and consumer stocks may outperform, and we are focusing the Fund's exposure on investments in those areas. We continue to find positive potential in technology, as advancements spread into more of the products and services we use daily. On the other hand, we hold a more skeptical outlook for the energy sector, which we believe is facing a supply overhang as the continued growth in alternative energy sources erodes stable, long-term returns as well as asset values of fossil fuels. Given high current market valuations and geopolitical tensions, however, we will temper our sanguine outlook with some caution. To help mitigate some of those risks in the portfolio, we continue to focus on holding stocks of quality companies with high returns on capital, sustainable competitive advantages, and low debt levels as compared with their peers. Pioneer International Equity Fund | Annual Report | 11/30/17 7 Please refer to the Schedule of Investments on pages 16-21 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, economic, and political conditions. To the extent the Fund invests in issuers located within specific countries or regions, the Fund may be particularly affected by adverse markets, rates, and events, which may occur in those countries and regions. 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. 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 or sectors. These risks may increase share price volatility. Before investing, consider the product's investment objectives, risks, charges and expenses.

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.

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 International Equity Fund Based on actual returns from June 1, 2017, through November 30, 2017. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 6/1/17 -------------------------------------------------------------------------------- Ending Account $1,079.10 $1,074.39 $1,081.11 Value (after expenses) on 11/30/17 -------------------------------------------------------------------------------- Expenses Paid $ 7.19 $ 11.75 $ 5.16 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.38%, 2.26% and 0.99% for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). 14 Pioneer International Equity Fund | Annual Report | 11/30/17 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads), or redemption fees that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer International Equity Fund (the "Fund") is the sole portfolio comprising Pioneer Series Trust VIII, 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 long-term growth of capital. The Fund offered three classes of shares designated as Class A, Class C and Class Y shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and 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 shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset management companies located throughout the world. Amundi, one of the world's largest asset managers, is headquartered in Paris, France. As a result of the transaction, Pioneer Investment Management, Inc., the Fund's investment adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned subsidiary of UniCredit S.p.A. In connection with the transaction, the names of the Fund's investment adviser and principal underwriter changed. Effective July 3, 2017, the name of Pioneer Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc. (the "Adviser") and the name of Pioneer Funds Distributor, Inc. changed to Amundi Pioneer Distributor, Inc. (the "Distributor"). Pioneer International Equity Fund | Annual Report | 11/30/17 29 In October 2016, the Securities and Exchange Commission ("SEC") released its Final Rule on Investment Company Reporting Modernization. In addition to introducing two new regulatory reporting forms (Form N-PORT and Form N-CEN), the Final Rule amends Regulation S-X, which impacts financial statement presentation, particularly related to the presentation of derivative instruments. The Fund's financial statements were prepared in compliance with the amendments to Regulation S-X. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") that require the management of the Fund to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. The Fund is an investment company and follows investment company accounting and reporting guidance under U.S. GAAP. 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. 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 third party pricing source. Trading in non-U.S. equity securities is substantially completed each day at various times prior to the close of 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. securities. 30 Pioneer International Equity Fund | Annual Report | 11/30/17 Securities 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 November 30, 2017, no securities were valued using fair value methods (other than securities valued using prices supplied by independent pricing services, broker-dealer 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. 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. Pioneer International Equity Fund | Annual Report | 11/30/17 31 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 disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the Statement of Operations from the effects of changes in the market price 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 November 30, 2017, 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 in the Statement of Operations. Tax returns filed within the prior three years remain subject to examination by federal and state tax authorities. In addition to meeting the requirements of the Internal Revenue Code, the Fund may be required to pay local taxes on the recognition of capital gains and/or the repatriation of foreign currencies in certain countries. During the year ended November 30, 2017, the Fund paid no such taxes. 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 overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. At November 30, 2017, the Fund reclassified $138,112 to increase undistributed net investment income, $109,104,796 to decrease accumulated net realized loss on investments and $109,242,908 to decrease paid-in capital to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. 32 Pioneer International Equity Fund | Annual Report | 11/30/17 At November 30, 2017, the Fund was permitted to carry forward indefinitely $2,063,325 of short-term losses under the Regulated Investment Company Modernization Act of 2010 without limitation. During the year ended November 30, 2017, a capital loss carryforward of $8,933,286 was utilized to offset net realized gains by the Fund. The tax character of distributions paid during the fiscal year ended November 30, 2017 and November 30, 2016 were as follows: --------------------------------------------------------------------------- 2017 2016 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $1,556,373 $3,049,827 --------------------------------------------------------------------------- Total $1,556,373 $3,049,827 =========================================================================== The following shows the components of distributable earnings on a federal income tax basis at November 30, 2017: --------------------------------------------------------------------------- 2017 --------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 3,640,749 Capital loss carryforward (2,063,325) Net unrealized appreciation 30,792,668 --------------------------------------------------------------------------- Total $32,370,092 =========================================================================== The difference between book-basis and tax-basis net unrealized appreciation is attributable to the tax deferral of losses on wash sales and adjustments relating to Passive Foreign Investment Companies (PFICs). E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. The Distributor earned $10,039 in underwriting commissions on the sale of Class A shares during the year ended November 30, 2017. 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 International Equity Fund | Annual Report | 11/30/17 33 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 prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates and economic and political conditions. The Fund may invest a substantial amount of its assets in issuers located in a limited number of countries and therefore is susceptible to adverse economic, political or regulatory developments affecting those countries. 2. Management Agreement The Adviser manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.85% of the Fund's average daily net assets up to $500 million and 0.75% on assets over $500 million. For the year ended November 30, 2017, the effective management fee (excluding waivers and/or assumptions of expenses) was equivalent to 0.85% of the Fund's average daily net assets. Effective August 1, 2017, the Adviser contractually agreed to limit ordinary operating expenses (ordinary operating expenses means all fund expenses other than extraordinary expenses, such as litigation, taxes, brokerage commissions and acquired fund fees and expenses) of the Fund to the extent required to reduce fund expenses to 1.25%, 2.15% and 0.90%, of the average daily net assets attributable to Class A, Class C and Class Y shares, respectively. Prior to August 1, 2017, the adviser had contractually agreed to limit ordinary expenses to 1.45% and 2.35% for Class A and Class C shares, respectively, and Class Y shares did 34 Pioneer International Equity Fund | Annual Report | 11/30/17 not have an expense limitation. Fees waived and expenses reimbursed during the year ended November 30, 2017, are reflected on the Statement of Operations. These expense limitations will be in effect through April 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 $26,411 in management fees, administrative costs and certain other reimbursements payable to the Adviser, at November 30, 2017. 3. Transfer Agent Boston Financial Data Services, 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 shareholder communications activities such as proxy and statement mailings and outgoing phone calls. For the year ended November 30, 2017, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareowner Communications -------------------------------------------------------------------------------- Class A $68,221 Class C 9,081 -------------------------------------------------------------------------------- Total $77,302 ================================================================================ 4. Distribution Plan 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 Pioneer International Equity Fund | Annual Report | 11/30/17 35 shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $5,158 in distribution fees payable to the Distributor at November 30, 2017. 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 November 30, 2017, no CDSCs 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 credit facility in which the Fund participated until February 9, 2016 was in the amount of $240 million. The credit facility in which the fund participated until February 7, 2017, was in the amount of $220 million. Effective February 8, 2017, the Fund participates in a facility that is in the amount of $25 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate ("LIBOR") plus 0.85% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight Eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in 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 November 30, 2017, the Fund had no borrowings under the credit facility. 36 Pioneer International Equity Fund | Annual Report | 11/30/17 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust VIII and the Shareholders of Pioneer International Equity Fund: -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer International Equity Fund (the "Fund") (the sole fund constituting Pioneer Series Trust VIII), as of November 30, 2017, and the related statements of operations, changes in net assets and the financial highlights for the year then ended and the financial highlights for the year ended November 30, 2013. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audit. The statement of changes in net assets for the year ended November 30, 2016 and the financial highlights for periods ended November 30, 2014, November 30, 2015 and November 30, 2016 were audited by another independent registered public accounting firm whose report, dated January 25, 2017, expressed an unqualified opinion on the statement of changes in net assets and those financial highlights. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform audit of the Fund's internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of November 30, 2017, by correspondence with the custodian, brokers and others or by other appropriate auditing procedures where replies from brokers and others were not received. We believe that our audit provides a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer International Equity Fund at November 30, 2017, the results of its operations, the changes in its net assets, and the financial highlights for the year then ended and the financial highlights for the year ended November 30, 2013, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts January 25, 2018 Pioneer International Equity Fund | Annual Report | 11/30/17 37 ADDITIONAL INFORMATION (unaudited) 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 Funds 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, including the Fund's two most recent fiscal years, 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 a new independent registered public accounting firm, Ernst & Young LLP ("EY"), for the Fund's fiscal year ended November 30, 2017. 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 38 Pioneer International Equity Fund | Annual Report | 11/30/17 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 Funds 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 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.
