NEWPORT CORPORATION REPORTS

SECOND QUARTER AND FIRST HALF 2013 RESULTS

Irvine, California — July 31, 2013 — Newport Corporation (NASDAQ: NEWP) today reported financial results for its second quarter and six months ended June 29, 2013, and its outlook for the remainder of 2013.  The company noted the following regarding the second quarter results:

·    Net sales of $134.2 million;

·    New orders of $147.6 million;

·    Net income attributable to Newport of $2.7 million, or $0.07 per diluted share, when measured according to generally accepted accounting principles (GAAP);

·    Non-GAAP net income attributable to Newport of $7.8 million, or $0.20 per diluted share, excluding the amortization of intangible assets, stock-based compensation expense, integration, restructuring and severance costs, and the tax impact of the excluded amounts; and

·    Cash generated from operations of $21.8 million, and a reduction in debt of $10.2 million.

Commenting on the results, Robert J. Phillippy, Newport’s President and Chief Executive Officer, stated, “We are very encouraged by the rebound in new orders during the second quarter.  Our new orders increased 10.5% sequentially to $147.6 million and our book-to-bill ratio was greater than 1.0 in all of our target end markets.  As expected, our net sales and non-GAAP income increased slightly on a sequential basis.  In addition, we strengthened our balance sheet by generating $21.8 million in cash from operations and using $10.2 million of that cash to reduce our outstanding debt.”

Sales and Orders

Newport’s sales and orders by end market were as follows:

Notes:

(1)         Certain prior period amounts have been reclassified to conform to the current period presentation.

On a sequential basis, the company’s sales and new orders in the second quarter of 2013 increased 1.2% and 10.5%, respectively, compared with the first quarter levels, driven by increases in its microelectronics, industrial manufacturing and life and health sciences end markets, offset in part by lower sales to and orders from customers in the scientific research and defense and security end markets.  Commenting on the increase in orders, Mr. Phillippy said, “Our orders from microelectronics customers in the second quarter increased sequentially by $7.4 million, or 26.4%, over the first quarter level, despite the overall industry not yet showing signs of a full recovery.  We had a number of key design wins in the quarter that contributed to this result.  This gives us optimism that we are gaining share in this market during the current down-cycle, and will see accelerated growth from these new programs as the recovery in the semiconductor equipment industry gains momentum.”

Operating Income and Net Income

Newport reported operating income for the second quarter of 2013 of $5.6 million when calculated in accordance with GAAP, reflecting a 26.5% sequential increase compared with the first quarter of 2013.  On a non-GAAP basis, excluding the amortization of intangible assets, stock-based compensation expense, and integration, restructuring and severance costs, the company’s operating income for the second quarter of 2013 was $12.8 million, or 9.5% of net sales, a 14.6% increase compared with the first quarter of 2013.

The company reported net income attributable to Newport for the second quarter of 2013 of $2.7 million, or $0.07 per diluted share, when calculated in accordance with GAAP.  On a non-GAAP basis, net income attributable to Newport for the second quarter of 2013 increased 26% compared with the first quarter of 2013 to $7.8 million, or $0.20 per diluted share.

The company has provided a reconciliation of its gross profit, operating income, net income and net income per diluted share calculated in accordance with GAAP and on a non-GAAP basis following the statements of income and comprehensive income included in this release.  Management believes that the supplemental presentation of non-GAAP financial information provides insight into the company’s core business results, as well as a more meaningful comparison of its financial results between periods.

Cash, Cash Equivalents and Marketable Securities

As of June 29, 2013, the company had $161.4 million in total indebtedness and $102.0 million in cash, restricted cash and marketable securities.  On July 18, 2013, Newport announced the completion of a new $275 million revolving credit facility.  As part of this refinancing, the company paid all of the outstanding obligations remaining on its prior credit facility, and the fees relating to the new facility, by using $34.2 million in cash and borrowing $120.0 million on its new revolving credit line.  The new credit facility provides the company with greater flexibility from a borrowing capacity, cash flow and covenant perspective, with lower ongoing financing costs.

Financial Outlook

Commenting on Newport’s outlook, Mr. Phillippy said, “We expect our sales in the second half of 2013 to increase compared with the first half of the year.  In addition, we believe that our growing backlog, coupled with new business wins related to our strategic growth initiatives, will position us well for increasing sales and profitability in 2014.  In the third quarter of 2013, we expect our net sales to be in the range of $136 million to $143 million, resulting in sequential increases in our non-GAAP operating income and non-GAAP earnings per diluted share over the second quarter levels.”
