Six Flags Entertainment Corporation (NYSE: FUN) saw its shares reverse a strong intraday advance on Tuesday, September 22, 2026, as news of multiple lawsuits tied to its X2 roller coaster rattled investors. The stock, which had climbed as much as 3.9% earlier in the session, closed the day down 0.6% at $12.30, erasing all gains as legal concerns overshadowed broader market optimism.
Lawsuits Allege Catastrophic Injuries
Three separate complaints have been filed alleging catastrophic brain injuries linked to the X2 ride at Six Flags Magic Mountain. Attorney Gary Dordick of Dordick Law Corporation, who is representing the plaintiffs, stated that more than 100 additional riders have retained his firm, though none of those claims have yet been formally adjudicated. The lawsuits were announced during a press conference held at 11 a.m. Pacific Time, which coincided with a sharp reversal in the company's share price.
Financial Exposure Remains Unquantified
The financial implications for Six Flags are still unclear. The company self-insures a portion of its guest liability, meaning it may be responsible for covering a significant share of any settlements or judgments. As of June 28, 2026, Six Flags reported total self-insurance reserves of $141.3 million, comprising $45.5 million in current reserves and $95.8 million in non-current reserves. However, these figures cover the entire portfolio of guest and employee claims, not just the new X2 cases.
Adding to the pressure, Six Flags carries nearly $5 billion in long-term debt, which stood at $4,971.9 million at the end of the second quarter. The company's cash position was $134.5 million, with an additional $702.8 million available under its revolving credit facility. While the company has not commented on the pending litigation, the combination of potential liability and existing leverage could weigh on its financial flexibility.
Stock Performance and Analyst Views
The stock's intraday reversal on September 22 was notable. After opening at $12.66, shares reached an intraday high of $12.85, representing a 3.9% gain from the prior close of $12.37. By the time the press conference began, the stock had slipped to $12.39, and it closed at $12.30, down 0.6%. Trading volume was 1.83 million shares, up 15.7% from the previous session.
Analyst recommendations issued before the lawsuits remain on the books, with price targets ranging from $22 to $24, implying potential upside of 78.9% to 95.1% from the current price. However, none of these targets reflect the potential impact of the new allegations.
Operational Context and Risks
Six Flags has been showing operational strength, with second-quarter same-park attendance up 4% and revenue increasing 2.4% to $864 million. Adjusted EBITDA rose 7% to $249 million. The company relies heavily on the second and third quarters, which historically account for about 70% of annual attendance and revenue, and it has identified fall events as an important operating period.
The X2 coaster has been closed since mid-July while California authorities investigate two recent incidents. If additional claims emerge or if the state's investigation leads to prolonged closure, it could impact attendance at Magic Mountain and potentially other parks. Conversely, a quick resolution and adequate insurance coverage could alleviate investor concerns.
Attorney Gary Dordick indicated that more complaints are expected in the coming weeks. The next key developments to watch will be California's decision on reopening the ride and any adjustments to Six Flags' claim reserves in its next quarterly filing.
