Silicon Motion's Q1 results were a game changer

Silicon Motion notched non-GAAP (adjusted) earnings per share of $1.58 on sales of $342.1 million. For comparison, the average analyst estimate had called for the business to post a profit of $1.30 per share on sales of roughly $299.6 million. Sales for the quarter were up 23% on a sequential basis and 105% year over year. SSD controllers, eMMC+UFS controllers, and Ferri & Boot Drive solutions each saw strong annual revenue growth in the period, and the near-term performance outlook appears very promising.

What's next for Silicon Motion?

While Silicon Motion's Q1 results breezed past Wall Street's targets, its guidance for the current quarter actually looked even stronger. At the midpoint of its guidance range, the company is calling for revenue of roughly $402 million -- exceeding the previous average analyst estimate by $95 million.

The company's guidance for an adjusted gross margin between 48.5% and 49.5% modestly exceeded Wall Street's forecast, and its target for an adjusted operating margin between 21% and 22% came in far better than anticipated. Even better, management guided for sequential sales growth in each quarter this year -- suggesting that performance should be even stronger in the back half.
