BWX Technologies, Inc. (NYSE:BWXT) today announced that it has received an inaugural investment grade credit rating of BBB with a Stable Outlook from Fitch Ratings, Inc. ("Fitch"). Fitch assigned BWXT’s revolving credit facility a BBB+ rating and its 4.125% senior notes due in 2028 and 2029, BBB ratings.

"We are pleased to receive a BBB investment grade rating from Fitch, reflecting our critical role in providing nuclear solutions to national security and commercial power customers, strong financial position and disciplined approach to capital allocation," said Mike Fitzgerald, BWXT’s chief financial officer. "This achievement reflects the actions we have taken to optimize our balance sheet while maintaining the financial flexibility to invest in our business and support long-term growth."

In assigning the rating, Fitch cited BWXT’s strong position in providing critical nuclear reactor components and fuel for the U.S. naval propulsion and other strategic government programs, backed by its specialized licenses, intellectual property and ability to meet stringent regulatory requirements. Fitch also cited multi-year revenue visibility and cash flow stability, supported by BWXT’s robust backlog, as well as its conservative financial policy and financial flexibility to fund growth initiatives while maintaining leverage consistent with the investment grade rating.
