Shares of Citrix Systems ( CTXS) moved higher in after-hours trading Wednesday after the company posted higher second-quarter earnings that edged Wall Street estimates.

The Fort Lauderdale, Fla.-based provider of access infrastructure systems said earnings rose to $31.5 million, or 18 cents a share, from $23 million, or 17 cents a share, last year.

Excluding the amortization of intangible assets, net income rose to $35.4 million, or 20 cents a share, from $31.1 million, or 18 a share, a year earlier. On that basis, analysts had expected the company to earn 18 cents a share in the latest quarter, according to Thomson First Call.

Sales increased 24% to $178.3 million from $143 million a year earlier, driven by strong deferred revenue growth, a "solid" performance in the company's online division, and new agreements with customers France Telecom and the U.S. Air Force.

Revenue was slightly above analysts' expectations of $175.7 million.

For the third quarter, the company expects to earn 19 cents to 21 cents a share on revenue of $175 million to $185 million, in line with the current consensus estimates.

Shares of Citrix were up 10 cents to $16.60 after closing down more than 4% to $4.07 in the regular session.
