Platinum Equity LLC of Beverly Hills, listed in Forbes' annual List of America's Largest Private Companies through 2015, was reclassified as a private equity firm in 2016 and determined to be no longer eligible for the list.
Parsons Corporation, long on the Los Angeles Almanac's list of the largest privately-owned companies based in Los Angeles County, ended this status after it announced on February 28, 2019, that, effectively immediately, its corporated headquarters was relocated from Pasadena (where it had been based since its founding in 1944) to Centreville, Virginia.
