Six Flags falls 13% after a fatal coaster incident, with $4.9 billion of debt unchanged

Six Flags Entertainment shares fell about 13% in early trading on Tuesday after a rider died on the Goliath roller coaster at Six Flags Over Georgia on Monday afternoon. Nasdaq showed the stock at $10.39 at 9:50 a.m. ET, down $1.53 from Monday's $11.92 close, and just above the bottom of its 52-week range of $10.45 to $27.37 as Nasdaq lists it.

The company has not said what caused the death. CNBC reported that one person died and several were injured shortly before 4 p.m. Monday, that police gave no further details, and that Six Flags said it was cooperating with the investigation. Fox Business, citing local stations, said Cobb County officials confirmed the fatality and that detectives are investigating. Authorities have not publicly determined the cause.

What has actually closed

A Six Flags spokeswoman told Atlanta's WSB-TV the company had "temporarily closed similar attractions across our parks" out of caution. Fox Business, relaying local station reports, named at least nine coasters at six other parks: Goliath at Magic Mountain, Nitro at Great Adventure, Raging Bull at Great America, Orion and Diamondback at Kings Island, Behemoth and Leviathan at Canada's Wonderland, and Fury 325 and Thunder Striker at Carowinds. No reopening dates have been announced. We do not know whether that list is complete, and the company has not published one.

The number behind the move: equity took the hit, debt did not

Nasdaq puts the company's market value at about $1.07 billion at the 9:50 a.m. quote. Working back from Monday's close, that is roughly $157 million less than it was at the end of Monday's session. Six Flags' own second-quarter release shows net debt of $4.88 billion at June 28: $4.99 billion of borrowings, less $135 million of cash.

Add the two and the whole company is valued at about $5.95 billion. Shareholders own about 18% of that. A $157 million drop in equity is a 13% fall for the stock but only about 2.6% of total value, because the debt sits underneath it at the same size as yesterday. That is the leverage working in reverse: small changes in what the business is worth hit the shares hard, and the lenders are first in line.

Interest is the fixed cost that keeps arriving whatever the rides are doing. Net interest expense was $102 million in the second quarter alone and $377 million over the 12 months to June 28, per the same release. The balance sheet showed $115 million of shareholder equity, down from $1.77 billion a year earlier.

What the filing says about the cushion

The company reported $837 million of liquidity at the end of June, including $703 million of undrawn revolving credit, so near-term cash is not the obvious worry. The exposure is revenue. Management said season-to-date pass sales were up 7% and the active pass base up 6% on a same-park basis, and described passes as providing "visibility into peak season demand." Prepaid passes are only worth as much as the rides that are open, and a safety review that keeps flagship coasters closed or sours families on the brand is the risk to watch, not this quarter's ticket sales.

We have no figure yet for how much revenue the closed rides carry, and none of the three outlets above gave one. Anyone quoting a dollar cost this early is guessing. As of this morning the most recent 8-K on SEC EDGAR is the August 6 results release, so there is no company filing on the incident or its financial effect.

Who it hits

Shareholders carry the first loss, as above. Bondholders and lenders have a thinner but real exposure: the cheaper the equity gets, the less cushion sits under their $5 billion. Activist investor Jana Partners was already pressing the company to explore a sale, and we covered that case, including how little of the purchase price is equity, here. A fatal incident and an open investigation make a buyer's due diligence harder, and the stock's fall makes any premium cheaper in absolute terms.

For the seasonal staff and local suppliers around each park, the question is how long the closures last. That is unknown today. The thing to watch is the investigation's findings and any company statement on when the rides reopen.
