SAN JOSE, Calif.--(BUSINESS WIRE)--Techwell, Inc. (NASDAQ: TWLL), a leading provider of mixed signal integrated circuits for multiple video applications in the security surveillance, automotive and consumer markets, today announced financial results for the first quarter ended March 31, 2008.

First Quarter 2008 Highlights:

First Quarter 2008 Results:

Total revenue for the first quarter of 2008 was $15.6 million as compared to revenue of $16.5 million in the preceding quarter and $13.5 million in the first quarter of 2007. Total revenue was within the previously stated guidance range of $15 million to $16 million and was comprised of $11.6 million in security surveillance, $1.7 million in LCD display, $2.1 million in video decoders and $188,000 of other revenue.

“Our first quarter results were highlighted by annual revenue growth of approximately 15 percent and a 400 basis point improvement to gross margin year-over-year,” stated Hiro Kozato, President and Chief Executive Officer of Techwell. “During the quarter, we continued to experience strong demand, particularly for our security surveillance products, even when considering the effects of typical seasonality and the Lunar New Year holiday. Additionally, as a result of our ongoing strategic R&D efforts, we introduced five highly integrated LCD Display processors for the automotive infotainment market.”

Mr. Kozato continued, “Looking forward, we remain optimistic about the growth prospect in our two key markets, security surveillance and automotive infotainment. We believe we are well positioned to capitalize on the positive market trends in these markets during 2008.”

Gross margin for the first quarter was 61 percent, consistent with the previous quarter and compares to 57 percent reported in the same period a year ago. Operating expenses for the first quarter totaled $7.2 million, or 46 percent of total revenue. This compares to operating expenses of $7.2 million, or 44 percent of revenue, in the preceding quarter and $5.0 million, or 37 percent of revenue, in the same period one year ago.

Net income for the first quarter of 2008 was $1.9 million compared to net income of $2.5 million in the first quarter of 2007. Earnings per diluted share of $0.09 for the first quarter of 2008 compares to $0.11 in the first quarter of 2007. Net income for the first quarter of 2008 was negatively impacted by an increase in the effective tax rate to 39% compared to an effective tax rate of 28% in the first quarter of 2007.

Net income includes pre-tax stock-based compensation expenses of approximately $1.7 million equating to a $0.08 per diluted share charge. Net income for the first quarter of 2007 included pre-tax stock-based compensation expenses of approximately $750 thousand equating to a $0.03 per diluted share charge. Shares used to compute net income per diluted share for the first quarter of 2008 and 2007 totaled 21.8 million shares.

Cash, cash equivalents and short and long term investments increased by $2.8 million to a total of $71.2 million increasing from approximately $68.4 million at December 31, 2007. This quarter’s total ending balances compares to approximately $57.0 million at March 31, 2007.
