Key Details

• Transaction date: February 6, 2026. Form 4 filed February 10, 2026 (within required 2 business days; timely).
• Transactions reported: A (award/grant) — 5,062 RSU shares at $0.00; M (exercise/conversion of derivative) — 11,564 shares acquired (derivative disposed/converted, reported at $0.00/N/A).
• Total shares acquired on this date: 16,626. No dollar value of the transfer of shares is reported in the filing (market value depends on AMTM share price at that time).
• Shares owned after the transaction: not specified in the provided filing excerpt.
• Relevant footnotes: F1/F5 — the RSUs were distributed upon vesting (vested on Feb 6, 2026). F4 — each RSU equals a contingent right to one share. F2 — references a prior non‑reportable transfer tied to Jacobs Solutions’ pro‑rata distribution (May 30, 2025). F3 — RSUs were originally set to vest at the next annual meeting but vested Feb 6 per F5.
• Transaction codes: A = award/vesting; M = exercise/conversion of derivative.

Context
Vesting of RSUs and conversion of derivative awards are common forms of executive/director compensation and do not necessarily indicate a buy or sell opinion by the insider. The filing shows no immediate sale of the acquired shares (no cashless sale reported). Because no market-value total is reported here, retail investors should multiply the number of shares by the AMTM share price on Feb 6, 2026 to estimate the economic size of the transaction.
