Six Flags Entertainment Corp
Six Flags Entertainment Corporation (formerly Tierco Group, Inc., Premier Parks, Inc., and Six Flags Inc.) was an American multinational amusement park corporation, headquartered in Arlington, Texas, United States. Before its 2024 merger with Cedar Fair, it had 27 properties in its portfolio. These included 15 amusement parks and 11 water parks in the United States, Canada, and Mexico. In 2019, Six Flags properties hosted 32.8 million customers, the seventh-highest attendance in the world. Founded in the 1960s and named for its first theme park, Six Flags Over Texas, the original company operated as Six Flags, Corp., and later Six Flags Theme Parks, Inc. From 1993 to 1998, Time Warner owned the company before selling it to Premier Parks, which absorbed the original company. Premier Parks adopted the Six Flags name after the acquisition. On June 13, 2009, the corporation filed for Chapter 11 bankruptcy protection, which it exited after corporate restructuring on May 3, 2010. In November 2023, Six Flags and Cedar Fair announced they would merge in a deal valued at US$8 billion. Both companies were dissolved and a new entity founded: Six Flags Entertainment Corporation, of which Six Flags shareholders received a 48.8% minority stake. The merger was finalized on July 1, 2024, at which time the combined company operated 42 properties.
