Shares of Verint Systems Inc., Long Island's largest software maker, slipped in after-hours trading Wednesday after the company released first-quarter financial results that fell short of the expectations of analysts.

Verint stock dropped 6 percent, to $62.40, after the company said its sales rose to $270.4 million during the three months that ended in April. That's up 5 percent from the same period one year ago -- but short of the $275 million revenue forecast by analysts.

Verint reported a $416,000 net loss for the quarter, or 1 cent per share, as the Melville company continues to absorb expenses from buying and integrating KANA Software Inc., a Sunnyvale, California, business that expands the data-analysis software that Verint sells to corporations.

Shares of Verint are up 14 percent since 2014 and up 30 percent from one year ago.
