Warning: Spoilers ahead for episode 1 of HBO's "And Just Like That..."

Peloton's stock prices plunged after a beloved character featured on the "Sex and the City" reboot died after a workout.

On Thursday, the first two episodes of "And Just Like That…" premiered on HBO Max and have already shocked longtime fans. During the first episode, titled "Hello It's Me," we discovered that Carrie Bradshaw (Sarah Jessica Parker) is still married to her husband, Mr. Big (Chris North), after tying the knot during the 2008 "Sex and the City" film.

Unfortunately, Mr. Big dies from a heart attack after unclipping from his Peloton bike just 39 minutes into the first episode.

"And just like that, Big died," Carrie said in the episode.

When the episodes premiered on Thursday, Peloton's stock prices peaked at $46.14 by 3:00 p.m. ET — the highest price recorded over five days — but it quickly began to tumble as more fans tuned in.

NBC News reported that Peloton's stock prices dropped 11.3% alone on Thursday, marking the company's lowest point in 19 months. The company's stock price slid to $40.69 by 4 p.m. ET that day and continued to fall to $38.51 by close on Friday.

In a statement to Insider, a Peloton representative said that the company was unaware that one of its bikes would be used in the premiere.

"Due to confidentiality reasons, HBO Max did not disclose the broader context surrounding the scene in advance," the statement read.

In a separate statement to Insider, a cardiologist and member of Peloton's Health & Wellness Advisory Council appeared to distance the company from the episode premise.

"I'm sure SATC fans, like me, are saddened by the news that Mr. Big dies of a heart attack," Dr. Suzanne Steinbaum told Insider. "Mr. Big lived what many would call an extravagant lifestyle — including cocktails, cigars, and big steaks — and was at serious risk as he had a previous cardiac event in Season 6. These lifestyle choices and perhaps even his family history, which often is a significant factor, were the likely cause of his death."
