Stifel analyst Steven Wieczynski, in a note to investors partially titled "When Results Come Out at 11PM, Not Usually a Good Sign," said he expects shares of Six Flags to open significantly lower after its Q3 results came in softer than expected, driven by lower attendance and higher operating costs. He also believes park-level results will contribute to some investors' concerns over the health of the core regional theme park consumer. Additionally, management did not mention anything in the press release about their "aspirational goal" of $750M in modified EBITDA by 2020, noted Wieczynski. While "clearly disappointed," the analyst said he doesn't want to jump to conclusions and panic without hearing from management and getting some answers, so he retains a Buy rating on the shares ahead of the company's earnings call.
