Jana Pushes Six Flags Sale as $4.9B Debt Weighs on Bids

The remaining parks improved on a same-park basis in the second quarter. A buyer would still inherit a capital-intensive business with roughly $5bn of debt, $300m-$320m of expected 2026 cash interest and $400m-$425m of planned capex.

Jana Partners has renewed its push for Six Flags Entertainment to explore a sale, asking the board to hire an investment bank after a second quarter the activist considers disappointing. Jana and its partners hold an economic interest of about 9%.

The demand is an escalation, not a new campaign. Jana called for a sale in March and has pressed for board and portfolio changes for months. The fresh question is whether Six Flags' operating improvement at its continuing parks is enough to support a transaction across a much more difficult capital structure.

On a reported basis, second-quarter revenue fell 7% to $865 million and attendance declined 7%, partly because Six Flags had sold or closed parks. The continuing portfolio looked better: same-park revenue rose 2.4%, attendance increased 4% and adjusted EBITDA rose 7% to $249 million.

The same-park numbers give a buyer evidence of operating improvement. The debt determines how much of that improvement can reach equity.

The financing burden is larger than the activist headline

Six Flags ended June with $4.883 billion of net debt. Net interest expense was $102 million in the second quarter and $197 million in the first half. Management expects 2026 cash interest of roughly $300 million to $320 million and capital spending of $400 million to $425 million.

The company has already paid more to refinance. In January it issued $1 billion of 8.625% notes due 2032 to replace notes carrying coupons around 5.4% to 5.5% that were due in 2027. Other major debt maturities extend into 2031 and 2032.

That makes the sale discussion an enterprise-value question. A buyer needs enough park-level cash generation to fund maintenance and growth capex, service the debt and still earn an equity return. The recent same-park improvement helps the numerator. Refinancing cost and leverage keep the denominator demanding.

Asset sales have simplified the portfolio. Six Flags sold six non-core parks to EPR Properties and has closed other sites, which may make the remaining estate easier to underwrite. But a leaner portfolio does not remove weather volatility, maintenance requirements or the need to keep spending on attractions that support attendance.

Jana's renewed pressure can force a price discovery exercise the public market has not provided. If credible buyers emerge despite the debt and capital needs, the same-park recovery may be worth more under different ownership. If financing terms cap bids, the process will show how much of Six Flags' equity value is being consumed by a balance sheet built for a cheaper-money era.
