BUTH JAY S. 4

What Happened Jay S. Buth, Vice President, Controller and Chief Accounting Officer of Eversource Energy (ES), received a grant of 1,311 performance/share awards on January 27, 2026. To satisfy tax withholding related to that award, 335 shares were disposed on February 12, 2026 at $70.22 per share, generating proceeds of $23,524 (disposition reported as code F — tax withholding). This was an award/grant event rather than a market sell by choice.

Key Details

• Award: 1,311 performance shares and related dividend equivalents determined 2026-01-27 (no cash price; reported as acquisition code A).
• Tax withholding sale: 335 shares disposed on 2026-02-12 at $70.22/share, total $23,524 (code F — shares withheld/sold to satisfy taxes).
• Net from award: 1,311 total award consisted of 50% deferred (655 shares) per the reporting election; the remaining immediate portion less the withheld 335 shares leaves 321 shares delivered to the insider. Total net shares attributable to the award = 976 (321 immediate + 655 deferred).
• Footnotes: filing re-reports dividend equivalents tied to the performance award and clarifies composition (deferred shares, restricted share units, dividend equivalents). Shares held in Eversource 401(k) plan are noted separately (per plan record keeper).
• Filing timeliness: transaction dated 2026-02-12 was reported on Form 4 filed 2026-02-17 (five days later), which appears to be later than the typical two-business-day Form 4 reporting requirement.

Context This filing documents a performance-share award and a routine tax-withholding disposition — not an open-market sale. Such withholding/surrender of shares to cover taxes is common after equity awards and doesn’t necessarily indicate the insider is selling for investment reasons. The report re-states dividend equivalent amounts for accuracy; no option exercise or 10% owner transaction is involved.
