Blue Bird Corporation became a publicly traded company through its 2014 merger with Hennessy Capital Acquisition Corp, the blank-check vehicle that traded under ticker HCAC and was sponsored by Hennessy Capital Group. The combination, which closed in February 2014, placed Blue Bird — a Macon, Georgia-based manufacturer of school buses and commercial vehicles — among the first wave of SPAC-driven transportation sector listings. The company subsequently traded under ticker BLBD and has since expanded its product lineup to include electric and alternative-fuel school buses. Blue Bird filed an 8-K with the SEC on March 17, 2025. Sign up at SpacDesk for full filing history, sponsor profiles, and deal analytics on this and hundreds of other SPAC transactions.
