Item 2.02 Results of Operations and Financial Condition.

On October 23, 2026, the Federal Home Loan Bank of Boston (the “Bank”) issued a press release announcing its preliminary, unaudited results for the quarter ended September 30, 2026, and the declaration of a dividend. The Bank’s board of directors declared a cash dividend equal to an annual yield of 6.72 percent, the approximate daily average SOFR yield for the third quarter of 2026 plus 300 basis points. The dividend, based on average stock outstanding for the third quarter of 2026, will be paid on November 3, 2026. The press release, which should be reviewed for further details on each of these developments, is furnished herewith as Exhibit 99.1 to this report.

*************************************************************************************

The information being furnished in this Item and contained in Exhibit 99.1 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section, and shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

This report, including Exhibit 99.1, uses forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, which include statements with respect to the Bank’s plans, objectives, projections, estimates, or predictions. These statements are based on the Bank’s expectations as of the date hereof. The words “preliminary”, “expects”, “anticipates”, “will”, and similar statements and their plural and negative forms are used in this notification to identify some, but not all, of such forward-looking statements. For example, statements about future declarations of dividends and expectations for advances balances, mortgage-loan investments, and net income are forward-looking statements, among other forward-looking statements herein. The Bank cautions that, by their nature, forward-looking statements involve risks and uncertainties, including, but not limited to, the application of accounting standards relating to, among other things, the amortization and accretion of premiums and discounts on financial assets, financial liabilities, and certain fair value gains and losses; changes and volatility of such changes in interest rates, market prices, and indices; hedge accounting of derivatives and underlying financial instruments; the fair values of financial instruments; the allowance for credit losses on investment securities and mortgage loans; instability in the credit and debt markets; economic conditions; changes in demand for advances or consolidated obligations of the Bank or the Federal Home Loan Bank system; the Bank's ability to execute its business model and pay future dividends; and prepayment speeds on mortgage assets. In addition, the Bank reserves the right to change its plans for any programs for any reason, including but not limited to, legislative or regulatory changes, changes in membership, or changes at the discretion of the board of directors. Accordingly, the Bank cautions that actual results could differ materially from those expressed or implied in these forward-looking statements or could impact the extent to which a particular plan, objective, projection, estimate or prediction is realized, and you are cautioned not to place undue reliance on such statements. The Bank does not undertake to update any forward-looking statement herein or that may be made from time to time on behalf of the Bank.
