Vitesse Semiconductor Corp. narrowed its net loss in the fiscal fourth quarter as it increased product adoption by customers and added 130 customers. The Camarillo integrated-circuit manufacturer reported a net loss of $2.5 million (-4 cents a share) in the quarter ended Sept. 30, compared with a net loss of $5.8 million (-10 cents) in the same period a year earlier. Revenue increased 7 percent to $28.7 million. Chief Executive Chris Gardner said that during the quarter Vitesse made investments by adding employees for hardware and software development and in marketing and sales. He said business was particularly strong in supplying chips for the devices that connect devices to the Internet, the so-called “Internet of Things.” “While our legacy business has declined over the past several years, our new business is growing rapidly,” Gardner said in a prepared statement Shares closed up 33 cents, or more than 10 percent, to $3.43 on the Nasdaq. Wesco Aircraft Holdings Inc. appointed Jennifer Pollino to fill a vacancy on its board of directors. The Valencia aerospace supplier named Pollino, an executive coach and consultant, to its board on Thursday with her term expiring at the 2015 annual stockholders meeting. Pollino will serve as well on the board’s compensation committee. Pollino founded business consultancy JMPollino LLC in 2012. Prior to that, she served as an executive vice president for human resources and communications at Goodrich Corp., in Charlotte, N.C. She also serves on the board of aerospace and industrial manufacturer Crane Co., in Stamford, Conn., and the Society for Human Resources Management, in Alexandria, Va. “(Pollino’s) long track record in the industry and strong background as a business leader, human resources expert and financial professional bring a diverse and unique perspective and a strong skill-set to Wesco Aircraft,” Chief Executive Randy Snyder said in a prepared statement.
