Diodes Inc. reported double-digit growth in profit as well as sales; however the company still missed Wall Street’s expectations.

Diodes Inc. reported first quarter net income of $13 million (47 cents per share), up 40 percent from $9.3 million (34 cents ) from the same period a year earlier. Without stock option expenses, earnings would have been 50 cents a share, the company said which is still below the 52 cents per share Wall Street analysts were expecting, according to a poll conducted by Thomson Financial.

Revenue for the Westlake Village-based semiconductor maker was also up 25 percent to $92 million thanks mainly to an expanded product offering as well as strong sales, the company said.

Diodes also said it anticipates a strong second half of the year, with second-quarter revenue 2 percent to 5 percent higher than the first quarter.

Shares in Diodes were up 25 cents to $37.88 in afternoon trading Friday on the Nasdaq.
