Life Time Fitness Inc. stock hit the mat Thursday after the company reported slower membership growth and a higher attrition rate among members.
Less-than-expected earnings guidance for the full 2012 year also contributed to the decline.
Shares in the Chanhassen-based health club chain fell more than 12 percent before an afternoon rally recouped some of the loss. Nevertheless, the stock closed at $45.15, down $4.13 a share, or 8.4 percent.
The decline followed release of Life Time's first-quarter results: Revenue rose 11.6 percent to $268.4 million from $240.6 million compared with the same quarter last year, and net income was $25.7 million, or 62 cents per share, compared with $20.8 million, or 51 cents per diluted share, for first quarter 2011.
At least one analyst thought the market overreacted to the first-quarter news and a year-end earnings-per-share estimate of $2.65 to $2.73 when Wall Street had expected $2.75.
"Big story obscured: Margins massively higher; growth may accelerate," said analyst Brent Rystrom in an early note to investors.
Piper Jaffray & Co. analyst Sean Naughton, who reiterated his buy recommendation on the company Thursday, said LifeTime's 3.8 percent increase in core membership was the lowest in six quarters. Naughton said the attrition rate increased as the company raised dues.
"I still feel good about the company given the improvement on operating margins and the improving employment environment" that could lead to new members, Naughton said.
