Online health education provider HealthStream posted a profit of $2.4 million in the second quarter, a jump of 32 percent from a year ago. Per diluted share, earnings came in at 9 cents, in line with analysts' expectations.

Revenues at the downtown-based company rose 23 percent to $25.8 million, helped by a 12 percent growth in contracted subscribers. Operating margins climbed more than 80 basis points to 15.6 percent, helped by small increases in marketing and administrative expenses. Also flattering comparisons with a year ago was that HealthStream's annual customer summit took place in the second quarter, cutting operating profits by $270,000. (This year's summit took place in Q1.)

“Our patented electronic portfolio product gained through our recent acquisition of Decision Critical is an exciting addition to our product portfolio — and we are making investments to offer it as an integrated platform extension to customers by early next year,” said CEO Bobby Frist. “Also, the HealthStream Performance Center — launched in March — and the HealthStream Competency Center, combined, were newly contracted in the second quarter by 15 healthcare organizations.”

Analyst Richard Close at Avondale Partners said HealthStream's numbers met his expectations and noted that Frist's team reiterated its profit forecasts. But he also noted that he is looking for more details on expenses for the quarter.

"We need additional information to understand if this is a timing issues or foreshadowing a slowdown in upcoming quarters," Close said.
