What: Shares of cloud software and services provider Interactive Intelligence Group (ININ) soared on Tuesday following the company's fourth-quarter earnings report. Interactive Intelligence beat analyst estimates for both revenue and earnings, driven by strong growth in recurring revenues. At 11:30 a.m. ET, the stock was up about 17.5%.

So what: Interactive Intelligence reported fourth-quarter revenue of $107.7 million, up 16.4% year over year and about $2.5 million higher than the average analyst estimate. Recurring revenue, which includes both cloud subscriptions and support fees, rose 24% year over year to $63.4 million. Cloud subscription revenue alone grew 53% to $29 million, while license and hardware revenue rose 2.4%, and services revenue increased by 16%.

Non-GAAP EPS came in at $0.12, down from $0.26 during the prior-year period, but $0.09 better than analyst expectations. On a GAAP basis, the company posted a net loss of $0.16 per share, compared to a loss of $1.42 per share during the fourth quarter of 2014. GAAP operating expenses grew by 23% year over year, quite a bit faster than revenue.

Now what: This jump in the stock price following Interactive Intelligence's earnings report comes after a difficult year for the stock. The company's stock price has slumped by about 40% over the past year, excluding Tuesday's gains, with investors likely concerned about slowing revenue growth and persistent losses. Even after Tuesday's gains, the stock has lost about two-thirds of its value since early 2014.
