Shares of Six Flags Entertainment tumbled after a report said the amusement park operator temporarily closed some of its rides in the U.S. and Canada. The shutdowns came after a rider died and several others were injured at a park in Georgia on Monday afternoon, local police said.

Six Flags suspended operations for its Goliath roller coaster at Six Flags Over Georgia, where the incident took place Monday afternoon, The New York Times reported. The company also temporarily shuttered eight similar attractions across other parks "out of an abundance of caution." It remains unclear when operations will resume.

Investors were frazzled following the announcement, sending shares down 14% to $10.21 on Tuesday. Shares were heading to a closing price at their lowest level in nearly 17 years, according to Dow Jones Market Data.

The Cobb County Police Department said in a statement to Barron's that a rider died and several people were injured following an incident Monday afternoon on a roller coaster at Six Flags Over Georgia in Austell, Georgia. Officers responded to the scene, and detectives will investigate the circumstances.

Additional details about the death, or number of people injured, weren't available.

A Six Flags representative didn't say whether the accident took place on the Goliath, an attraction that reaches about 200 feet and rides at 70 miles an hour, the Times reported.

Six Flags didn't respond to a request from Barron's to confirm the information.

The temporary closure of multiple rides represents one of Six Flags' rides most extensive sweeps since 2020, when operations were disrupted by the Covid-19 pandemic.

The incident Monday added to the growing scrutiny surrounding Six Flags' safety practices. Less than a month ago, three people sued Six Flags and roller coaster manufacturer S&S Worldwide, arguing they sustained catastrophic brain injuries on the X2 roller coaster at Six Flags Magic Mountain in Southern California.

The legal complaints claimed Six Flags failed to adequately warn passengers of the injury risks. The nearly 200-foot-tall X2 roller coaster hurls riders at speeds of up to 76 miles an hour while spinning them by as much as 360 degrees.

In terms of the company's financial performance, Six Flags has continued to grapple with the aftermath of its massive $8 billion merger with Cedar Fair and softer core attendance. In its fiscal second quarter earnings, released on Aug. 6, revenue dropped 7% from the year before to $865 million, falling short of Wall Street's calls for nearly $928 million, according to FactSet.

Adding to the headwinds, shares have dropped 32% this year as of the close of trading Monday, according to Dow Jones Market Data.

Still, the numbers haven't scared Wall Street analysts away. The average rating on Six Flags stock is Overweight, according to the 17 analysts polled by FactSet. 65% recommend buying the stock, while 29% have a Hold rating.
