Seaport (SEG) CEO Matthew Partridge Receives Equity Awards

What Happened

Matthew Morris Partridge, CEO of Seaport Entertainment Group Inc. (SEG), received equity awards on Feb 26, 2026: 27,625 restricted stock units (RSUs) and 55,148 derivative option awards. Both grants are reported at $0.00 per share (no cash paid).
These are grants/awards (not open-market purchases or sales) and do not represent immediately tradable shares. The RSUs and options become valuable only if and when they vest and (for options) are exercised.

Key Details

Transaction date: 2026-02-26; Form 4 filed: 2026-03-02 (within the SEC’s 2-business-day filing window).
RSUs: 27,625 units granted at $0.00. Footnote F1: each RSU equals a contingent right to one share; vesting in three substantially equal annual installments beginning Feb 27, 2027, subject to continued service.
Derivative/options: 55,148 units granted at $0.00 (reported as derivative). Footnote F2: options vest in four substantially equal annual installments beginning Feb 26, 2027, subject to continued service.
Shares owned after the transaction: not specified in the provided filing excerpt.
No indication of 10b5-1 plan, cashless exercise, tax-withholding sale, or late filing in this report.

Context

These awards are standard equity compensation: they signal the company is granting future compensation tied to tenure/performance, but they are not immediate purchases by the insider and should not be interpreted as an immediate bullish or bearish trade.
For the options, value depends on future stock price and whether Partridge exercises them after vesting; RSUs will convert to company shares only as they vest.
