CA Technologies, the Long Island-born software giant, said Thursday that its fiscal first-quarter revenue dipped on faltering sales and adverse foreign exchange rates.

The company, which sells software to large corporations, said sales fell 9 percent, to $977 million in the three months that ended in June, compared to the same period last year. CA's quarterly profit slipped 2.3 percent, to $212 million.

"While our overall first-quarter total revenue and new sales declined year-over-year, I am quite encouraged by the positive trend over the past three quarters in enterprise solutions new sales growth rates," chief executive Mike Gregoire said in a statement.

CA became one of the nation's largest software makers by selling mainframe programs to credit card companies, banks and other large enterprises. As mainframe sales have slipped, CA has struggled to reinvent itself through cloud-based software and other programs.

The company released its first-quarter earnings after the close of regular trading on Wall Street. CA shares fell less than 1 percent in after-hours trading, to $29.90.

CA was based for 22 years in Islandia before moving its corporate office to Manhattan last year. It still employs roughly 1,400 people on Long Island.
