Dice Holdings Inc.’s earnings declined in the second quarter due to significant decreases in recruitment activity at Urbandale-based Dice.com and eFinancialCareers.

Dice Holdings reported a net income of $2.8 million, or 4 cents per share, in the second quarter, compared with $7.6 million, or 12 cents per share, in the year-ago period. Revenues were down 33 percent to $27 million.

DCS Online revenues, which represent 74 percent of Dice Holdings’ total revenues, were down 27 percent as a result of fewer Dice.com recruitment package customers and a decrease in the average monthly revenue they generate.

Total operating expenses declined 29 percent to $8.8 million, which included a 47 percent decrease in sales and marketing expenses. Net cash provided by operating activities was $4.1 million at the end of the quarter, compared with $13.5 million a year ago.

On June 10, Dice Holdings acquired AllHealthcareJobs.com, a career site dedicated to matching health-care professionals with jobs, expanding the company’s focus on technology and financial services recruiting. The deal was for $2.8 million in cash and 205,000 shares of newly issued Dice Holdings common stock. An additional $1 million is payable upon achievement of certain operating and financial goals in 2011.

“Despite the ongoing significant downturn in recruitment activity, we continue to deliver strong profit margins,” said Scot Melland, chairman, president and CEO of Dice Holdings. “We are pursuing our strategic initiatives as evidenced by the acquisition of AllHealthcareJobs.com in the second quarter. By entering the health-care vertical, we have expanded our market opportunity and are actively extending the value of our specialized approach to a large, new set of customers.”
