Six Flags is closing some of its parks primarily due to poor financial performance and low profit margins. One example is the planned closure of California's Great America in 2027 because it ranks very low in profitability. This park's lease ends in 2028, and the company sees more value in marketing the property for redevelopment rather than continuing operations. Similarly, Six Flags America in Maryland is also closing because it no longer fits the company's strategic long-term growth plan. Both closures reflect the company's broader effort to optimize its park portfolio by shutting down locations with the lowest returns and repurposing valuable real estate assets. Operational challenges and staffing issues also contribute to the decline in park viability.
