IAC Stock July 31Slower than expected ticket sales through its Ticketmaster division contributed to IAC/InterActiveCorp’s quarterly profit increasing less than analysts’ projections, the company announced earlier today.

Total ticket revenue was $302.7 million for the quarter ended June 30, trailing the $343.7 million estimated by Aaron Kessler, an analyst at Piper Jaffray & Co., according to the Bloomberg wire service.

“People may be selling more of their own tickets,” Jeffrey Lindsay, an analyst at Sanford C. Bernstein & Co. in New York, told Bloomberg. “The contract renewals they’re getting are probably on poorer terms.”

In addition, revenue fell at IAC’s HSN home-shopping division, leading to shares of the company’s stock falling the most in three months.

Second-quarter net income rose 78 percent to $96 million, or 32 cents a share, from $53.8 million, or 17 cents, a year earlier, according to IAC.

U.S. consumers, faced with higher gasoline costs and a slumping housing market, spent less on concert tickets and arranged fewer high-margin home loans.

“We did not anticipate the softness in domestic ticketing volumes,” IAC’s CEO Barry Diller said in a prepared statement. “We are not satisfied with these results, whether driven by market conditions or our own hand, and are taking every appropriate action.”

Operating income fell 33 percent to $54.4 million on increased selling and marketing expenses. Revenue climbed 5.6 percent to $1.51 billion, the New York-based company said. Analysts surveyed by Bloomberg estimated an average of $1.59 billion.

Home values in 20 U.S. cities fell the most in at least six years in May as a glut of unsold properties, mounting defaults and higher mortgage rates suggest the housing recession has yet to touch bottom, according to the S&P/Case- Shiller index issued today.
