The company grew by acquisition, starting with struggling airlines "Inter-Continental Airlines" and "Atlantic Coast Air Systems", renaming them to "LexAir". When rising profits were threatened by fuel shortages, LexCorp bought out Southwestern Petroleum and renamed it "LexOil". This pattern of acquisition continued to include the Daily Planet and several Metropolis businesses before LexCorp sold the unprofitable Daily Planet and its building to TransNational Enterprises, establishing an L-shaped 96-story high-rise as its new headquarters.
