Pittsburgh Book of Lists / Largest Companies Rankings

Overview

The Pittsburgh Business Times Book of Lists / Largest Companies rankings are annual data-driven lists that rank the largest companies in the Pittsburgh region by metrics such as revenue, employees, and other key indicators. Produced editorially by the Pittsburgh Business Times, the lists are compiled from surveys and verified research rather than a traditional awards nomination process. Companies pursue inclusion for regional visibility, competitive benchmarking, and as a third‑party credibility signal in local business development. The Book of Lists is widely used by executives, sales teams, and investors as a trusted reference for the Pittsburgh business community.
