Greater Washington lost two slots on the ever-evolving Fortune 500 this year.
The region has 15 companies on the list, down from 17 a year ago. Arlington-based CalAtlantic Group, No. 415 last year, was removed after being acquired by Miami-based Lennar. And Host Hotels and Resorts of Bethesda, which came in last year at No. 472, fell just outside of the top 500, ranking No. 502. The list is based on 2017 revenue.
