NEWPORT CORPORATION REPORTS

FIRST QUARTER 2011 RESULTS

— Record First Quarter Sales and Orders —

Irvine, California – April 27, 2011 – Newport Corporation (NASDAQ: NEWP) today reported financial results for its first quarter ended April 2, 2011. The company noted the following highlights regarding its first quarter results:

Robert J. Phillippy, Newport’s President and Chief Executive Officer, stated, “The Newport team delivered another excellent performance in the first quarter of 2011. Our sales of $128.4 million and orders of $129.7 million were records for a first quarter. We continued to demonstrate our very strong profit leverage on these robust sales, with exceptional gross margin, net income and earnings per diluted share.

Net Income

Newport reported net income of $20.8 million, or $0.53 per diluted share, in the first quarter of 2011 when calculated in accordance with generally accepted accounting principles (GAAP), compared with net income of $5.1 million, or $0.14 per diluted share, in the first quarter of 2010. Included in this total was a gain of $7.2 million, or $0.18 per diluted share, resulting from a non-recurring currency translation adjustment. Without this gain, the company would have recorded net income of $13.6 million, or $0.35 per diluted share. A reconciliation between the company’s net income and net income per diluted share calculated in accordance with GAAP and on a non-GAAP basis is provided following the statements of income included in this release.

The company’s net income in the first quarter, excluding the currency translation gain, was more than double the level in the first quarter of 2010, due primarily to the company’s higher sales and continued strong operational execution in the 2011 period.

Financial Outlook

Commenting on the company’s financial outlook, Mr. Phillippy stated, “Our financial results for the first quarter of 2011 continued to reflect the solid foundation for growth we established in 2010. Our backlog and orders momentum are very strong, and we have continued to demonstrate our ability to deliver significant profit leverage on increases in sales. In the second quarter of 2011, we anticipate increasing our sales 12% to 15% over the $114.6 million recorded in the second quarter of 2010 and leveraging that revenue growth into operating income that is more than 50% higher than the year ago period. In addition, based on our robust orders levels, strong and growing presence in our markets and effective operational execution, we expect continued revenue growth in the full year 2011. We also expect to increase earnings per diluted share on a GAAP basis by more than 50% compared with the $1.09 recorded in 2010. Excluding the non-recurring currency translation gain of $0.18 per diluted share discussed earlier in this release, we expect our 2011 non-GAAP earnings per diluted share to be more than 35% higher than the 2010 level.”
