2026 Executive Incentive Plan

On March 10, 2026, the Federal Home Loan Bank of Boston’s (the “Bank’s”) board of directors (the “Board”) adopted the 2026 Executive Incentive Plan (the “EIP”), an incentive compensation plan for certain Bank officers, which is effective for fiscal year 2026. The Bank's principal executive officer, principal operating and financial officer, and other named executive officers are participants in the EIP.

Named Executive Officers' Incentive Goals

As EIP participants, each named executive officer has an incentive award opportunity calculated at the conclusion of 2026 using weighted performance goals and based on the Bank’s results as of December 31, 2026.

The following table sets forth the goals and related weighting for each of the named executive officers participating in the EIP.

______________________________________________________________________________

(1)“Core Return on Equity” means A divided by B. “A” is net income for fiscal year 2026 reported in accordance with accounting principles generally accepted in the United States of America adjusted for the following: (a) deducting fee income resulting from the exercise of prepayment options on financial instruments (net of gains or losses from the unwinding of hedges) less imputed amortization of historical prepayment fee income; (b) removing debt retirement costs (net of gains or losses from the unwinding of hedges) less imputed amortization of historical debt retirement costs; (c) removing net unrealized gains and losses attributable to derivatives and hedging activities and net unrealized gains and losses on trading securities; (d) adding imputed amortization of premiums and accretion of



discounts on investment securities classified as trading securities; (e) removing interest expense on mandatorily redeemable capital stock which represents dividends payable to holders of Class B Stock that has been classified as mandatorily redeemable capital stock; and (f) removing expenses for payments made under Bank established disaster relief programs. “B” is the sum of (a) the Bank’s average daily balance of capital stock, including mandatorily redeemable capital stock, outstanding during fiscal year 2026; and (b) the Bank’s average daily balance of retained earnings during fiscal year 2026.

(2)Achievement of the goal is subject to compliance with the Bank's market value of equity to par stock ratio and internal unfloored duration of equity limits for at least 10 of the 12 months of the year. If this requirement is not met, the Board may use its discretion to reduce or eliminate payouts for this goal.

(3)Each of the performance levels will be adjusted up or down by 1.0 basis point for every basis point by which the average daily federal funds rate is greater than or less than the 3.34 percent rate assumed for 2026 in an internal Bank forecast.

(4)This goal measures the number of housing units created or preserved in projects approved for funding in the Bank’s 2026 Affordable Housing Program. To qualify, housing units must be affordable to households with income at or below 80% of the area median income.

(5)This goal measures MPF portfolio growth based on the change in the monthly average unpaid principal balance from December 2025 to December 2026. A loan is excluded from the calculation once it enters real estate owned status.    

(6)A member user is defined as a member that enrolls (i.e., receives a commitment of funding from the HCI Program to support the member’s commitment to fund a loan to its customer) one or more qualifying transactions into the Housing Our Workforce, Jobs for New England, CDFI Advance, Lift Up Homeownership, or the Equity Builder Program, sells a loan into the MPF Permanent Rate Buydown Program, or submits a completed application for the Affordable Housing Program, in 2026. The total number of member users is the sum of member users in the aforementioned HCI Programs, counted separately for each program. A given member will count only once per HCI Program.

(7)For each product category – advances, letters of credit, and Mortgage Partnership Finance® (MPF®)*– the Bank will determine the number of members utilizing a Bank product within each product category in 2026. A given member may be counted up to three times depending on the number of product categories in which they participate.

(8)Achievement of the goal is determined by insurance company members’ utilization of certain advances in 2026 with each advance type accumulating a number of points to be tabulated after year end. Daily Cash Manager Advances (i.e., overnight advances), except those for less than $100,000, receive 1 point, with each insurance company member counted only once. Advances with terms greater than 1 day but less than 30 days receive 2 points with each insurance company member counted only once. Advances with terms greater than or equal to 30 days and less than 1 year receive 3 points, with each insurance company member counted only once. Advances with terms greater than 1 year receive 4 points for each such advance opened in 2026, and there is no limit to how many times an insurance company member may be counted. For advances where the Bank holds the option to cancel, the final maturity of the advances shall be used to determine the term of the advance. For advances where the member holds the option to cancel (or floating rate advances where the member



can prepay without a fee on reset dates) and (a) the first call (reset) date is less than 1 year from the open date, the first call (reset) date will determine the term of the advance and the advance will count only once or (b) the first call (reset) date is one year or longer from the open date, there is no per-member limit.

(9)This goal measures the average daily balance of advances outstanding to insurance company members in 2026.

(10)This goal measures the number of risk mitigation projects, as prioritized by the Operational Risk Committee, that have been implemented in 2026.

Named Executive Officers' Incentive Award Opportunities under the EIP
Under the EIP, named executive officers are assigned an incentive award opportunity expressed in the following table as a percentage of the participant's 2026 base salary at December 31, 2026.

_________________________________________________________________________________
(1) Maximum incentive payable in March of any year equals 100% of the plan year base salary.

Each EIP participant's goal achievement and resulting individual award will be determined based on results as of December 31, 2026. Named executive officers will be eligible to receive fifty (50) percent of such award in a cash payment no later than March 15, 2027. The remaining portion will be treated as a deferred award payable in March 2029.
Payment of the non-deferred portion of the awards based on the goals is subject to:

the requirement that the participant be in employment with the Bank on December 31, 2026, although participants that terminate employment by reason of death or disability or who are eligible to retire prior to that date may receive a pro-rata payment of the award in certain instances as detailed in the EIP; and
Board approval and non-objection of the Federal Housing Finance Agency, the Bank’s principal regulator (the “FHFA”), if required.

Deferred Portion of Award Payable after Year-end 2028
The deferred award is equal to the deferred portion of the 2026 award with an interest credit based on the compounded average of daily SOFR from January 1, 2027 to December 31, 2028.
The receipt of the deferred award is subject to:




the requirement that the participant be in employment with the Bank on December 31, 2028, although participants that terminate employment by reason of death or disability or who are eligible to retire prior to that date may receive payment of the award in certain instances as detailed in the EIP; and
Board approval and review and non-objection by the FHFA, if required.

Additionally, at the discretion of the Board, deferred awards may be reduced (but not to a number that is less than zero) for all EIP participants or for an individual participant, as applicable, if, during calendar years 2027 and/or 2028, any of the following occurs such that if it had occurred prior to the year-end 2026 calculations, it would have negatively impacted the goal results and reduced the associated payout calculation:

operational errors or omissions resulting in material revisions to the 2026 financial results, information submitted to the FHFA supporting the goal results or payout calculation, or other data used to determine the award at year-end 2026;
submission of significant information to the Securities and Exchange Commission, Office of Finance (the Bank’s agent for the issuing and servicing of debt), and/or the FHFA materially beyond any deadline or applicable grace period, other than late submissions that are caused by acts of God or other events beyond the reasonable control of the participants; or
failure by the Bank to make sufficient progress, as determined by the FHFA, in the timely remediation of examination and other supervisory findings relevant to the goal results or payout calculation.

EIP Administration

The EIP is administered by the Board’s Human Resources and Compensation Committee (the “Compensation Committee”), which has full power and binding authority to construe, interpret, and administer the EIP, and to adjust it for extraordinary circumstances without the consent of any EIP participant. The Compensation Committee has the right at any time to amend, suspend, or terminate the EIP in whole or in part, for any reason, and without the consent of any EIP participant, but will not do so without re-submission to the FHFA (except for amendments that reduce payout amounts). Participants must receive a performance rating of “meets expectations” or better for fiscal year 2026 in order to be eligible to receive an EIP payout. Subject to certain limited exceptions in the case of termination of employment by reason of death or disability or in certain instances of retirement, an EIP participant whose employment terminates prior to the end of the plan year will not be entitled to any award, except as otherwise determined by the Bank’s president/chief executive officer, with the concurrence of the Compensation Committee, in its sole discretion and subject to the review of the FHFA, if required.
