Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal integrated circuits (ICs), today reported record third quarter revenue of $149.5 million, an impressive 25 percent increase compared to the third quarter of 2011. The company believes market share gains across the portfolio and record design win activity are enabling the business to outperform the end markets.
Third quarter revenue was up ten percent sequentially due to both organic growth and the additional revenue from an acquisition completed during the quarter. On a GAAP-basis, gross margin was 57.9 percent, which included one-time charges associated with the acquisition. R&D investment increased to $34.8 million, and SG&A expense decreased to $24.5 million. SG&A expense declined primarily due to an $8.1 million gain from the purchase of the company’s headquarters. Resulting GAAP operating income increased to 18.2 percent. Diluted GAAP earnings per share declined to $0.24 and included other charges related to the acquisition of Ember and a net gain from the purchase of the headquarters buildings.
The following non-GAAP results exclude the impact of stock compensation and other one-time items. Gross margin was 61.0 percent for the quarter. Operating expenses decreased to 39.1 percent of sales. R&D increased to $31.7 million, and SG&A increased to $26.7 million due to the acquisition and increased variable compensation. Operating income, therefore, was better than expected at 21.9 percent of revenue. Strong revenue growth and operating performance resulted in significant earnings leverage.
