Gibraltar (ROCK) GC Katherine Bolanowski Receives RSU Award

What Happened

Katherine Bolanowski, General Counsel, Vice President and Secretary of Gibraltar Industries (ROCK), was granted 259.22 restricted stock units (RSUs) on 2026-06-30. The filing records an acquisition price of $0 because these are derivative RSU awards rather than a cash purchase.

Key Details

Transaction date: 2026-06-30; Form 4 filed 2026-07-01 (filed one day after the grant).
Transaction type/code: A (award); reported as a derivative award.
Shares/units granted: 259.22 RSUs; recorded price: $0 (not a cash purchase).
Shares owned after transaction: Not specified in the filing.
Footnotes:
- F1/F3 — These are matching RSUs allocated in connection with the Reporting Person’s deferral of a portion of salary and/or annual cash incentive under the Company’s 2018 Management Stock Purchase Plan.
- F2 — RSUs are forfeited if service as an officer terminates before the 5th anniversary of the vesting commencement date; if service continues beyond that, RSUs are payable in cash (lump sum or in 5 or 10 annual installments as elected) beginning six months after termination. Each RSU converts to cash equal to the fair market value of one share at the date of termination.

Context

This is an award of restricted stock units (a deferred, cash-settled equity-type award), not an open-market purchase or sale. The listed $0 acquisition price reflects that no cash was paid at grant; the eventual value to the insider will depend on the fair market value when the RSUs convert to cash per plan terms.
