W. R. Berkley Jr., a reported 10% owner of W. R. Berkley Corporation (WRB), had 98,593 performance-based restricted stock units (RSUs) vest on August 3, 2026 (awarded at $0). To satisfy tax withholding obligations, 4,139 shares were withheld/disposed at $72.29 per share for a total tax cost of $299,198.

Key Details

• Transaction dates: August 3, 2026 (reported on Form 4 filed Aug 5, 2026).
• Codes: A = Award/Grant (98,593 shares @ $0.00 acquired); F = Tax withholding (4,139 shares disposed @ $72.29, $299,198).
• Vesting breakdown (footnote): 2021, 2022 and 2023 performance tranches — 38,841; 29,264; and 30,488 shares respectively, totaling 98,593 (performance period ended June 30, 2026).
• Shares reported as beneficially owned include 3,275,694 shares underlying RSUs that have vested but whose receipt has been deferred (per footnote). The filing does not list additional total common shares beyond these deferred vested RSUs.
• Footnotes clarify tax withholding was satisfied by withholding securities (routine), and the reporting person is manager of an LLC owned by the Estate and family trusts; the reporter is also co‑executor of the Estate (see Schedule 13D/A details).
• Filing appears timely: report period Aug 3, filed Aug 5 (standard Form 4 window).

Context
These transactions are the result of scheduled vesting of performance-based RSUs, not a market purchase or discretionary sale. The withholding of shares to cover taxes (code F) is a common, administrative step when awards vest. As a 10% owner connected to estate/family trusts, Berkley Jr.’s transactions reflect compensation/estate arrangements rather than an independent market sentiment signal.
