Shares of North America's largest roller coaster park operator, Six Flags Entertainment (FUN 3.66%), rose 9% this week after activist investing firm -- and major shareholder -- Jana Partners urged the company to sell itself. While the pop from this news is nice, Six Flags' stock remains 55% below its 52-week high.

Key Data Points
Jana originally bought a 4% ownership stake in Six Flags during the third quarter of 2025, but has been disappointed with the steps the company has taken so far to improve its operations.
The letter from Jana explained,
We have witnessed an alarming pattern of board dysfunction and disjointed decision-making that has become impossible to ignore ... It is now in the best interest of shareholders for the company to reverse course and engage with known buyer interest in Six Flags.

Jana would also like to see a new board chair announced. And Jana isn't the only activist investing firm pushing for changes from Six Flags following its tumultuous Cedar Fair acquisition and subsequently poor results. Sachem Head Capital Management also built a 5% stake in the company and added one of its executives to the board. Meanwhile, Land & Buildings Investment Management is pushing for the company to spin off its real estate assets into a REIT, potentially rearranging its heavy debt load and prompting a higher valuation.
I can't tell whether having this many activist investors in the same stock is positive news or leads to a "too many cooks in the kitchen" situation. Regardless, Six Flags has become an intriguing value stock to watch. However, with $5.4 billion in long-term debt and a market cap of only $1.8 billion, there is ample risk in a Six Flags investment. That said, the company sold seven of its 41 regional theme parks to EPR Properties for $331 million and refinanced $1 billion of debt from 2027 to 2032, helping its immediate debt issues. Trading at 10 times earnings before interest, taxes, depreciation, and amortization, Six Flags is reasonably priced, but too complicated for me to buy right now.
