Chip designer ARM Holdings is increasing its market share as the rest of the industry experiences a flat start to the year, Warren East, CEO of ARM Holdings, told CNBC on Tuesday.
ARM Holdings announced an adjusted pre-tax profit of 89.4 million pounds ($136.3 million) in the first three months of 2013, up 44 percent from a year earlier. Analysts had expected earnings of 77.6 million pounds or a 25 percent gain.
First quarter revenue rose 28 percent to 170.3 million from 132.5 million a year earlier.
ARM shares were up 6.4 percent after the results.
U.K.-based ARM designs and licenses chip designs that use less energy, making them popular among smartphone and tablet manufacturers.
"We've had a very good start to the year, we're ahead on revenue, ahead on profit and ahead on earnings, on the back of strong licensing in the first quarter and strong volume shipments of 2.6 billion chips," East told CNBC Europe's "Squawk Box."
