Jana Escalates Six Flags Campaign With Push to Weigh a Sale

A $202.6 million quarterly loss has sharpened the question facing Six Flags Entertainment: can its turnaround deliver more value than a buyer might pay for the whole company? Activist investor Jana Partners is urging the board to hire an investment bank and examine a sale, according to The Wall Street Journal.

The request follows Six Flags’ August results for the quarter ended June 28. Revenue fell 7% from a year earlier to $865 million, while the net loss more than doubled from $99.6 million. The company’s reported attendance also dropped 7%, to 13.1 million visits.

Those headline comparisons carry an important wrinkle. Six Flags had sold seven parks and stopped operating a Maryland location after the 2025 season, so its reported portfolio was smaller. On a same-park basis, revenue rose 2.4% and attendance increased 4%, according to the company’s earnings release. That offers some evidence of improvement at the parks it still operates, even as the much larger reported loss gives Jana a fresh argument for outside scrutiny.

The group disclosed an economic interest of about 9% in Six Flags in October 2025, alongside co-investors including Kansas City Chiefs tight end Travis Kelce. At the time, Jana’s campaign emphasized marketing, guest experience and operational changes. The latest demand moves the pressure toward a more consequential decision: whether the business should remain independent.

A sale review would not guarantee a deal. The board would have to assess buyer interest and whether a bid could outperform the company’s own recovery plan. Six Flags has been reshaping its park portfolio while trying to improve performance; selling the entire operator would be a different proposition from shedding individual properties.

Shares climbed in premarket trading Wednesday after the sale push became public, according to market reports. That reaction reflects the prospect of a transaction, not evidence that one is underway. Jana’s call asks the board to begin exploring options; Six Flags has not announced a sale process.
