APOG

Apogee Enterprises, Inc.

A North American maker of the glass and metal "skins" that wrap commercial buildings, Apogee Enterprises fabricates high-performance architectural glass with special coatings plus aluminum windows, storefronts, and curtainwall systems used by architects and builders. It began in 1949 as Harmon Glass, a Minneapolis auto-glass replacement shop that later moved into installing building glass and, in 2004, left the car business behind. The name comes from a 1960s investment club that its first CEO bought the rights to for a single dollar, picked to sound modern during the Space Age.

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.
