BWX Stock Plunges 8%, Wiping Out $953 Million, As Company Launches Debt Offering

BWX Technologies, which makes nuclear components, reactors and fuel, fell 7.89% to $121.42 in Wednesday trading as of 1:00 p.m. ET, erasing $953 million in market value, after it launched a $500 million senior notes offering due 2034.

Notes follow a credit line extension

The unsecured notes are guaranteed by the company's wholly owned subsidiaries that are obligors under its existing credit agreement.

A day earlier, BWX disclosed in an 8-K that its $1.25 billion revolver now runs to November 10, 2031. It also eased a lender covenant that applies if the company earns investment-grade ratings.

The stock was on pace for its biggest one-day drop since February 4, when it fell 9.9%.

A down year despite solid results

BWX shares were down about 24% year to date at Tuesday's close, while the S&P 500 was up about 11%. They sat 45% below their highest close of the past year, set April 15.

The company's third-quarter revenue rose 10% to $953.0 million, and net income was $102.0 million in its earnings release. Adjusted EBITDA rose 19% to $179.7 million.

On Monday it tightened 2026 adjusted earnings-per-share guidance to $4.72-$4.77, from $4.70-$4.80. It also set free cash flow guidance at $350 million-$360 million and introduced a preliminary 2027 outlook of high-single-digit revenue growth.

Where the business stands

BWX's Government Operations segment builds naval nuclear components, reactors and fuel for the U.S. Navy's propulsion program. Its Commercial Operations segment makes equipment for nuclear utilities and medical radioisotopes. The U.S. Government made up about 68% of 2025 revenue, and backlog was about $7.26 billion at the end of 2025.

Commercial revenue grew 25% in the quarter and government revenue 4%. CEO Rex Geveden said the company is in the "early-stages of a multi-decadal investment cycle" as customers seek nuclear answers to economic, national and energy security challenges.

The company's reactor technology was selected for the U.S. Army's Janus Program at Fort Campbell, and for a transportable nuclear power plant project in Canada.
