Ultratech Announces First Quarter 2013 Results

SAN JOSE, Calif.--(BUSINESS WIRE)--April 18, 2013--Ultratech, Inc. (Nasdaq: UTEK), a leading supplier of lithography and laser-processing systems used to manufacture semiconductor devices and high-brightness LEDs (HB-LEDs), today announced unaudited results for the three-month period ended March 30, 2013.

For the first quarter of fiscal 2013, Ultratech reported net sales of $60.6 million as compared to $49.6 million during the first quarter of fiscal 2012. Ultratech's net income for the first quarter of 2013 was $13.7 million, or $0.48 per share (diluted), as compared to net income of $10.2 million, or $0.38 per share (diluted), for the same quarter last year.

Arthur W. Zafiropoulo, Chairman and Chief Executive Officer, stated, “Through focused execution we achieved bottom line results in line with our expectations for the first quarter of 2013. As we previously indicated, the near-term business environment has been uncertain and will be challenging, but we anticipate that market conditions may improve as a result of anticipated increases in semiconductor capital equipment spending in the second half of the year.”

“Thanks to the continued support of our business partners, our strong relationships with customers and the continued efforts of our employees, we remain confident in our strategy to address our served markets in advanced packaging, laser spike annealing, and high-brightness LEDs,” continued Mr. Zafiropoulo. “Additionally, we are optimistic that we can continue to leverage our leading technology in both existing and adjacent target markets that offer potential growth opportunities.”

At March 30, 2013, Ultratech had $307.3 million in cash, cash equivalents and short-term investments. Working capital was $373.1 million and stockholders' equity was $14.44 per share based on 27,727,576 total shares outstanding as of March 30, 2013.
