FUND VOTING REPORT 811-02794 811-02794 549300V6TTODTL97GD50 Y During the reporting period, the MFS Global High Yield Fund, a series of the Registrant, voted at the November 14, 2024 shareholder meeting of the MFS High Yield Pooled Portfolio ("underlying fund"), another series of the Registrant. To address any potential conflicts of interest on the part of MFS that could arise from MFS voting shares of the underlying fund on behalf of the MFS Global High Yield Fund, MFS voted these shares in the same proportion as the votes cast by shareholders of the other funds that are series of the Registrant. As a result, the voting record for this meeting will reflect a split vote. Columns 10 and 12 for the underlying fund reflect dollars of net asset value. Due to rounding the amounts in Column 12 may not total the amount in Column 10. Additionally, the amounts in columns 10 and 12 for the unanimous written consent of the shareholders of MFS Series Trust XIV-MFS Institutional Money Market Portfolio reflect dollars of net asset value. 0 4 S000002427 MFS High Income Fund DMVGFZCV67YA34LSI126 S000002428 MFS Global High Yield Fund IAJ1R15XQSLN6MYDI525 S000002429 MFS Municipal High Income Fund ONQWW5HXR3GSM1QTA655 S000038262 MFS High Yield Pooled Portfolio 549300B758U8480GXX22 MFS SERIES TRUST III David DiLorenzo David DiLorenzo President and Principal Executive Officer 08/28/2025
