AYI

Acuity Inc.

A maker of lighting, building-management, and audio-video-control systems sold under brands like Lithonia Lighting, Holophane, Distech Controls, and Q-SYS, serving airports, universities, and retailers. It traces to 1946, when Lithonia Lighting began in a two-person garage in Lithonia, Georgia, later becoming a 2001 spin-off of National Service Industries; the name "Acuity" was chosen to signal sharp, focused leadership. Roughly half its finished goods come from Mexican Maquiladora plants with duty-free import status.
