Six Flags said its Magic Mountain park was worth $533.7 million less than it had thought, marking the biggest hit in a sweeping $1.5 billion write-down disclosed in its most recent quarterly report. The company’s valuation of Six Flags Magic Mountain was cut after a formal accounting test found that lower-than-expected revenue, earnings and cash flow had weakened the numbers behind the park.
That reduction made Magic Mountain the largest single drag in a list of non-cash losses that also included Six Flags Great America at $192.8 million, Six Flags Over Georgia at $187.9 million, Six Flags Fiesta Texas at $103.8 million, and Six Flags Great Adventure at $97.4 million. Six Flags also marked down Six Flags Mexico by $89.3 million, Six Flags Over Texas by $86.8 million, Schlitterbahn by $50.7 million, and the Six Flags trade name by $169.3 million, after once valuing that brand at $850 million.
Dennis Speigel, a longtime amusement-park consultant, said Six Flags had effectively admitted that a large part of what it thought it owned on paper was not worth what it claimed. He said the trade name is an asset only in the sense that it reflects a bet on the future, and that bet can turn out differently than expected.
The accounting test examined projected earnings, ticket sales, brand strength and other intangible assets known as goodwill. In this case, goodwill refers to the premium paid above tangible assets when Six Flags and Cedar Fair merged in 2024 in an $8 billion deal. The company said the entire $1.5 billion hit was a non-cash loss, meaning no money left the bank.
The scale of the adjustment matters because it lands after the 2024 merger was sold as a bigger, stronger theme-park company with valuable brands and parks spread across the country. Instead, the latest report shows that several of those assets are now worth far less on paper than they were when the deal was struck. Speigel said the accounting change is a reset to align the books with reality, and that is the clearest answer for investors watching what comes next.
