Key Details

  • Transaction dates: Feb 19, 2026 (two tranches) and Feb 20, 2026 (one tranche).
  • Execution: Open‑market/private purchases under a Rule 10b5‑1 trading plan (plan adopted Oct 3, 2025) — see footnote F1.
  • Weighted‑average prices reported; footnotes F2–F5 give the price ranges and offer to provide per‑trade breakdown on request.
  • Shares owned after the transactions: not specified in the provided summary (Form 4 typically reports post‑transaction ownership; consult the full filing for that number).
  • Filing timeliness: No late filing indicated (Form 4 filed Feb 20, 2026, within the usual 2‑business‑day requirement).
  • Ownership note: Shares are held directly by MSI.

Reporting persons also disclaim group status with WR Berkley & Others LLC (see remarks).

Context

  • This is institutional buying by a large shareholder (10% owner), executed under a pre‑arranged 10b5‑1 plan, not an executive/director personal trade. Institutional purchases can reflect portfolio decisions rather than individual insider sentiment.
  • For full details (per‑trade prices and post‑transaction holdings), retail investors should review the complete Form 4 filing (Accesssion 0001193125-26-061923) or request the breakdown referenced in the footnotes.
