Performance and attribution results are for the fund or share class depicted and do not reflect the impact of your contributions and withdrawals. Your personal performance results may differ.

0 FOR DEALER AND INSTITUTIONAL USE ONLY. - MFS Blended Research International Equity Fund PRPEQ-BRX-30-Jun-21 Fund Risks

The fund may not achieve its objective and/or you could lose money on your investment in the fund. Stock: Stock markets and investments in individual stocks are volatile and can decline significantly in response to or investor perception of, issuer, market, economic, industry, political, regulatory, geopolitical, environmental, public health, and other conditions. International: Investments in foreign markets can involve greater risk and volatility than U.S. investments because of adverse market, currency, economic, industry, political, regulatory, geopolitical, or other conditions. Emerging Markets: Emerging markets can have less market structure, depth, and regulatory, custodial or operational oversight and greater political, social, geopolitical and economic instability than developed markets. Strategy: There is no assurance that the portfolio's predicted tracking error will equal its target predicted tracking error at any point in time or consistently for any period of time, or that the portfolio's predicted tracking error and actual tracking error will be similar. The portfolio's strategy to target a predicted tracking error of approximately 2% compared to the Index and to blend fundamental and quantitative research may not produce the intended results. In addition, MFS fundamental research is not available for all issuers. Quantitative Strategy: MFS' investment analysis, development and use of quantitative models, and selection of investments may not produce the intended results and/or can lead to an investment focus that results in underperforming portfolios with similar investment strategies and/or the markets in which the portfolio invests. The proprietary and third party quantitative models used by MFS may not produce the intended results for a variety of reasons, including the factors used, the weight placed on each factor, changing sources of market return, changes from the market factors' historical trends, and technical issues in the development, application, and maintenance of the models (e.g., incomplete or inaccurate data, programming/software issues, coding errors and technology failures). Please see the prospectus for further information on these and other risk considerations.
