Shares of Six Flags Entertainment Corporation (FUN) plunged 6.12% in pre-market trading on Thursday, following the release of the company's disappointing first-quarter results for 2025. The sharp decline reflects investors' negative reaction to the theme park operator's financial performance.

According to the earnings report, Six Flags Entertainment posted a net loss of $219.7 million for the first quarter. This significant loss has raised concerns among investors about the company's financial health and near-term prospects, especially as the amusement park industry continues to navigate challenges in the post-pandemic landscape.

While detailed revenue figures were not provided in the available news, the substantial net loss suggests that Six Flags may be facing ongoing difficulties in attracting visitors and generating sufficient income to offset its operational costs. The pre-market stock plunge indicates that investors are reassessing their expectations for the company's performance in the upcoming peak summer season, which is crucial for theme park operators.
