NEWPORT CORPORATION ANNOUNCES NEW
$275 MILLION SECURED REVOLVING CREDIT FACILITY

Irvine, California — July 18, 2013 — Newport Corporation (NASDAQ: NEWP) today announced that it has entered into a new $275 million senior secured revolving credit facility, with a $50 million expansion option, through a syndicate of global financial institutions led by JPMorgan Chase Bank, N.A. The new credit facility replaces the Company’s existing $250 million senior secured credit facility, has a term of five years and initially bears an interest rate of 2.0% over LIBOR, or 1.0% over a base rate, at the Company’s option, with a commitment fee of 0.35% on the undrawn amount of the facility. The interest rate spreads and commitment fee are subject to adjustment in future periods based on the Company’s total leverage ratio, as set forth in the Credit Agreement. The facility is subject to customary covenants, including those relating to the Company’s total leverage and fixed charge coverage ratios.

Upon the closing of this new credit facility, Newport repaid its existing facility in full by borrowing $120 million under the new facility, and repaying the remainder from the Company’s cash balances, which reduced its outstanding senior secured debt by approximately $32.6 million. The Company is permitted to use the new facility for working capital, acquisitions, stock repurchases and other general corporate purposes.

Newport expects the lower interest rates and fees under the new facility, combined with the lower loan balance, to reduce its financing costs by approximately $0.5 million per quarter beginning in the third quarter of 2013. The Company will record a non-cash charge of $3.4 million in the third quarter of 2013 to write off the remaining unamortized balance of the previously capitalized fees related to the prior credit facility.

Commenting on the new facility, Charles F. Cargile, Newport’s Senior Vice President, Chief Financial Officer and Treasurer, stated, “We are very pleased to have completed this refinancing, which gives us significantly greater flexibility from a borrowing capacity, cash flow and covenant perspective, with lower on-going financing costs. We are confident that it will provide us with the liquidity we need to execute our strategic plan and fuel our future growth.”
