Six Flags Entertainment Corporation (NYSE:FUN) saw its stock rise 3.4% in premarket trading on Thursday after activist investor JANA Partners said it still holds roughly a 9% economic interest in the amusement park operator, even after a key member exited the group.
JANA disclosed that Dave Habiger has stepped away from the coalition to “pursue a complementary opportunity involving the Company.” Despite his departure, the activist fund and its partners remain invested at the same level.
The investor group — formed in October 2025 and counting NFL tight end Travis Kelce and former retail chief Glenn Murphy among its members — has been pressing for marketing, operational, and strategic changes aimed at boosting performance at the newly combined Six Flags–Cedar Fair entity.
Habiger, a former CEO of Lionsgate, had participated in the activist effort until November 13, 2025. His decision to leave to pursue what JANA called a “complementary opportunity” related to Six Flags hints at a potential role connected directly to the company, though no details have been provided.
The stock’s premarket jump suggests shareholders are encouraged that JANA’s influence remains intact despite the reshuffling within the group.
