Key Details

• Transaction date: 2026-03-31; filing date: 2026-04-02 (appears timely).
• Shares/units acquired: 130 phantom share equivalents at $279.25 each; total value $36,303.
• Form type: Derivative award (phantom share equivalents) — not shares delivered immediately.
• Shares owned after transaction: Not specified in the filing.
• Footnote: These are phantom share equivalents in Harrington’s Constellation stock fund account under a multi-fund, non‑qualified deferred compensation plan.

Context

• These phantom share equivalents are a cash-settled deferred compensation award, not an issuance of common stock. Such awards are routine for board members and are settled in cash upon departure, so they do not represent immediate voting or dividend ownership.
