BANGALORE, June 9 (Reuters) - National Semiconductor’s quarterly revenue topped estimates as sales to Asian handset makers offset a fall in shipments to its bigger cellphone customers, but profit missed expectations as margins shrunk.
Sales to its largest mobile phone customers fell in the fourth quarter but cross-selling in the segment after the Texas Instrument deal closes, should bring back growth, its chief executive said.
The company counts Nokia Oyj and Research in Motion as its largest mobile customers
“We will be able to more broadly address the phone market as compared to an individual company, ” Chief Executive Don Macleod said.
Mobile phone revenue accounted for 21 percent of the company’s revenue in the March-May quarter.
On Wednesday, Texas Instruments had warned of slower-than-usual quarterly sales at Nokia for its ailing cellphone growth as it scrambles to restart production after Japan’s massive earthquake.
The maker of chips used in products ranging from consumer electronics to industrial equipment said it expects first-quarter revenue to be flat compared with the current quarter but sees profitability to be hurt by acquisition costs.
National Semiconductor and Texas Instruments are still waiting approval from regulators in seven countries to consummate their $6.5 billion deal.
The Santa Clara, California-based company said fourth-quarter sales fell 6 percent to $374.1 million.
Analysts on average had expected revenue of $365.1 million, according to Thomson Reuters I/B/E/S.
Net profit for the quarter ended May 29 was $67.1 million, or 26 cents a share, down from $79.2 million, or 33 cents a share, last year.
Analysts were looking for a profit of 27 cents per share.
Shares of the company closed at $24.58 on Thursday on the New York Stock Exchange. (Reporting by Himank Sharma in Bangalore; Editing by Gopakumar Warrier)
