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

The company, which sells software to large corporations, said sales fell 6 percent, to $1.023 billion in the three months that ended in March, compared to the same period last year.

CA's quarterly profit, however, climbed 41 percent, to $151 million. That was largely because the company's fourth-quarter net income one year ago were hampered by $52 million in costs, mostly from a corporate restructuring.

"We still have work to do to drive the kind of growth that our company has the potential to achieve," chief executive Mike Gregoire said in a statement.

The company also released its outlook for the coming year, forecasting full-year sales of between $3.95 billion and $3.99 billion. That's down 2 percent from last year.

CA became one of the region'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.

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.
