ROCK
Gibraltar Industries, Inc.
A maker of building and infrastructure products based in Buffalo, NY, Gibraltar Industries produces metal roofing, gutters, and attic ventilation for homes, plus commercial greenhouse systems for agriculture. It was founded in 1972 as Gibraltar Steel Corporation, a small steel-processing shop that grew through acquisitions into a manufacturer spanning residential, renewable-energy, and infrastructure markets. Its stock ticker is ROCK—a nod to the Rock of Gibraltar and the strength that inspired its name—and its AgTech brand Prospiant builds turnkey greenhouses and even cannabis growing and extraction facilities.

Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: +33.4K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
