ANDOVER, Mass., Aug. 14, 2017 (GLOBE NEWSWIRE) -- MKS Instruments, Inc. (NASDAQ:MKSI), a global provider of technologies that enable advanced processes and improve productivity, announced today that Moody's Investors Service upgraded the Company's Corporate Family Rating to Ba1 from Ba2 and upgraded the company's senior secured term loan to Ba1 from Ba2.

In making the upgrade, the Moody's analysis cited the company's recent debt repayment and ongoing operating performance improvement as MKS continues to capitalize on growing demand for its products.

"The Moody's upgrades reflect our strong operating performance and our progress on delevering our balance sheet, and, as a result of these efforts, at the end of the second quarter of 2017, MKS became net cash positive," said Seth H. Bagshaw, Senior Vice President and Chief Financial Officer. "Since loan origination in April 2016, we've successfully repriced our Term Loan three times and completed five voluntary prepayments, which have reduced our annualized non-GAAP interest expense by approximately 50%."
