Putnam ETF Trust – Franklin Massachusetts Municipal Income ETF is an actively managed fixed-income exchange-traded fund that seeks to provide as high a level of current income exempt from U.S. federal income tax and Massachusetts personal income tax as is consistent with preservation of capital. The fund invests principally in Massachusetts tax-exempt municipal securities, including general-obligation bonds, revenue bonds, special-tax bonds, local-government obligations, transportation, utility, housing, education and health-care revenue bonds, and other municipal debt instruments; it emphasizes investment-grade securities with intermediate- to long-term maturities and may maintain cash and cash-equivalent positions. The fund is designed primarily for Massachusetts taxable investors seeking tax-advantaged municipal-bond income and is benchmarked against the Bloomberg Municipal Bond Index. Shares trade on NYSE Arca under the ticker FTMA, with monthly distributions, and the fund carries a 0.35% gross and net expense ratio. The portfolio is actively managed by Franklin Templeton Fixed Income, with Franklin Advisers, Inc. serving as investment manager and Franklin Distributors, LLC acting as distributor. The fund originated on October 23, 1989, and is domiciled in the United States. Its primary geographic investment focus is Massachusetts, which exposes the portfolio to economic, fiscal, legislative and regulatory developments in that state. The fund’s most significant recent strategic change occurred on November 7, 2025, when the Putnam Massachusetts Tax Exempt Income Fund reorganized into the Franklin Massachusetts Municipal Income ETF; the product began trading as an ETF on NYSE Arca on November 10, 2025, retaining an identical investment objective and substantially similar investment strategies to its predecessor mutual fund.
