Explanation of Responses:

Id	Content
F1	Grant of restricted share units (RSUs) which vest in three equal installments on February 15, 2027, 2028 and 2029. Restricted share units are distributable in Eversource Energy common shares on a one-for-one basis. RSU holders are entitled to receive dividend equivalents, exempt from line item reporting under SEC Rule 16a-11, to the same extent dividends are paid on common shares.
F2	Includes restricted share units and dividend equivalents thereon.
F3	Performance shares and dividend equivalent shares for the 2023-2025 Long-Term Incentive Program as determined on January 27, 2026.
F4	Shares held in trust under the Eversource 401k Plan, a qualified plan, according to information supplied by the Plan's record keeper.
F5	Reporting Person's deferred compensation under the Eversource Deferred Compensation Plan, a non-qualified plan, that is nominally invested as common shares. Each phantom share represents the right to receive one common share upon a distribution event, following vesting. Additional phantom shares are issued upon the automatic reinvestment of dividend-equivalents and are exempt from the line item reporting under SEC rule 16a-11.
