Gibraltar (ROCK) CEO William Bosway Sells 5,872 Shares for Taxes

What Happened William T. Bosway, President, CEO and a Director of Gibraltar Industries (ROCK), had 5,872 shares disposed (withheld) to satisfy tax obligations related to restricted stock units. The shares were reported at $45.48 each, for a total value of $267,059. This was a tax-withholding/settlement of RSUs—not an open-market sale.

Key Details

  • Transaction date and price: March 1, 2026 — 5,872 shares at $45.48; total $267,059. (Transaction code F = payment of exercise price or tax liability.)
  • Shares owned after transaction: Not specified in this Form 4 filing.
  • Footnotes: The shares relate to restricted stock units under the Company’s 2018 Management Stock Purchase Plan (matching and deferred RSUs). Footnotes note forfeiture if service ends before the 5th anniversary of vesting commencement and that RSUs are ultimately payable in cash (lump sum or installments) as described in the plan.
  • Filing timeliness: Reported on March 3, 2026 for a March 1, 2026 event—appears timely.

Context This transaction reflects routine tax withholding on granted/allocated RSUs rather than a discretionary open-market sale. Such withholding is common when equity awards vest or are settled and does not, by itself, indicate the insider’s view on the company’s stock. Purchases or open-market sales by insiders typically carry more interpretive weight for investors.
