Austin is headquarters for three Fortune 500 companies, but San Antonio beats us and is among the top 20 headquarters towns, tied with several others, at five. As we all know, Round Rock is headquarters for one. Texas is the number one state, serving as corporate headquarters for 56 of the 500. Austin’s three are Freescale Semiconductor (45th in Texas and 368th among the 500), Temple-Inland (51st in Texas, 433rd among the 500), and Whole Foods (52nd in Texas and 449th among the 500).
