Verint Systems Inc., a Melville-based maker of software used in managing call centers and tracking criminal and terrorist networks, Wednesday announced the death of Victor DeMarines, chairman of the board of directors.

DeMarines, 80, a former chief executive of MITRE Corp. who served as Verint board chairman since February 2013, died on Aug. 30, the company said. He had residences in Hollis, New Hampshire, and Bonita Springs, Florida.

The board appointed Verint chief executive and director Dan Bodner, 59, to succeed DeMarines as chairman. In 2002 Bodner led a spinoff of Verint from its corporate parent, Comverse Technology, and an initial public offering.

The disclosures came after Wednesday’s stock market close as Verint announced its second quarter financial results.

The company posted a 4.4 percent revenue increase for the quarter ended July 31 to $274.8 million.

Net loss narrowed to $5.8 million, or 10 cents per diluted share, from $11.1 million, or 19 cents per diluted share, in the 2016 quarter.

“We continue to expand our portfolio, offer our existing customers new solutions and win many new customers” in the call center business, Bodner said in a statement. “In cyber intelligence, our double digit revenue growth in the first half of the year was driven by demand for data mining solutions to address terrorism, crime, cyber-attacks, and other threats that remain pervasive around the world. We believe ongoing security threats present a long-term growth opportunity.”
