Activist investor Jana Partners is again urging Six Flags Entertainment Corp. to explore a sale, citing disappointment with performance and turnaround efforts. The investor wants the board to hire investment bankers for a strategic review, according to an unnamed source. Six Flags reported a 7% year‑over‑year decline in net revenue and lower attendance for the quarter ended June 28, with its stock down 45% over the past year. The company’s CEO, John Reilly, emphasized a strategy to increase guest engagement and long‑term value. Six Flags also agreed to sell seven non‑core parks in March. Jana previously teamed with co‑investors, including Travis Kelce, and sent a letter demanding a sale and new board chair. The pressure coincides with lawsuits from riders claiming brain injuries after a roller‑coaster incident in Southern California, highlighted by a CNN investigation. The Wall Street Journal first reported Jana’s latest push.

The activist’s renewed demand signals continued friction between Jana and Six Flags’ management, as the board faces both operational challenges and legal risks. Observers will watch whether a strategic review leads to a sale or operational changes to restore investor confidence.
