Magic Mountain is worth $533 million less than Six Flags thought after the parent company recalibrated high expectations for the Valencia amusement park that saw half a billion dollars in perceived value evaporate overnight.
Six Flags took a $1.5 billion write-down in the company’s most recent quarterly report following a formal accounting test triggered by lower than expected revenue, earnings and cash flow.

“Six Flags just admitted that a big chunk of what it thought it owned on paper wasn’t worth what it claimed,” International Theme Park Services CEO Dennis Speigel wrote on the company’s website.
The accounting test asked a simple question: How much are Six Flags amusement parks worth?
The answer: A lot less than Six Flags thought — at least on paper.

The tests looked at projected earnings, ticket sales, brand strength and other intangible assets — known as “goodwill” in accounting terms.
Goodwill is the premium paid above and beyond any tangible assets — roller coasters, thrill rides, buildings and land in the case of the $8 billion merger that combined Six Flags and Cedar Fair into a North American amusement park juggernaut in 2024.

“On paper, it’s an asset, but it’s really just a bet on the future,” Speigel wrote on the ITPS website. “And like all bets, it can go another way than originally anticipated.”

Magic Mountain saw $533.7 million removed from the Six Flags books.
Six Flags Great America ($192.8 million), Six Flags Over Georgia ($187.9 million), Six Flags Fiesta Texas ($103.8 million), Six Flag Great Adventure ($97.4 million), Six Flags Mexico ($89.3 million), Six Flags Over Texas ($86.8 million) and Schlitterbahn ($50.7 million) all took massive hits.

Even the Six Flags trade name, once valued at $850 million, lost $169.3 million on paper — a nearly 20% decline.
The $1.5 billion in write-downs by Six Flags were all non-cash losses, according to Speigel.

“No money left the bank,” Speigel wrote on the ITPS website. “This is purely an accounting adjustment. A reset to align the books with reality.”
