(LYNCHBURG, Va. - Aug. 4, 2025) BWX Technologies, Inc. (NYSE: BWXT) ("BWXT", "we", "us" or the "Company") reported second quarter 2025 results. A reconciliation of non-GAAP results is detailed in Exhibit 1.

“We had exceptionally strong second quarter 2025 financial results driven by solid operational performance and pacing of work, particularly in Government Operations, which was complemented by robust bookings in both segments, leading to record backlog,” said Rex D. Geveden, president and chief executive officer.

“The demand for nuclear solutions in the global security, clean energy, and medical markets continues to accelerate,” continued Geveden. “In our ten years as a standalone public company, BWXT has built significant industrial scale, leading to one of the broadest and highest quality portfolios in the nuclear market. Our robust manufacturing, processing, and servicing capabilities stem from decades of real nuclear experience and our strategic investments in innovation and efficiency; these are underpinned by our technical depth and long history of successfully delivering nuclear solutions to our customers. We remain focused on growth, operational excellence, and strategic investments to create value for our customers, and ultimately our shareholders.”

“Based on our strong year-to-date results, robust bookings, and favorable market outlook, we are increasing our 2025 financial guidance metrics,” said Geveden. “We now expect adjusted EBITDA of $565 million to $575 million, adjusted EPS of $3.65 to $3.75, and free cash flow of $275 million to $285 million.”

(2) Items named in the Financial Results Summary differ from names in BWXT Financial Statement. Operating Cash Flow = Net Cash Provided by Operating Activities; Capital Expenditures = Purchases of Property, Plant and Equipment; Dividends Paid = Dividends Paid to Common Shareholders

Second quarter revenue increased in both operating segments. The Government Operations increase was driven by higher naval nuclear component production, special materials processing, and contribution from the acquisition of A.O.T., partially offset by lower microreactor volumes. The Commercial Operations increase was driven by higher revenue associated with commercial nuclear components, higher medical sales, and contribution from the acquisition of Kinectrics, partially offset by lower field services activity due to the timing of life-extension and outage projects, as well as lower fuel handling revenue.

Operating Income and Adjusted EBITDA(1)

Second quarter GAAP operating income increased as an increase in Government Operations was partially offset by lower Commercial Operations and higher corporate expense, as well as restructuring and transformation, and acquisition related costs.

Second quarter non-GAAP(1) operating income increased as an increase in Government Operations and lower corporate expense was partially offset by lower Commercial Operations. The Government Operations increase was driven by higher revenue and solid operational performance. The decrease in Commercial Operations was mainly due to revenue mix, related to the timing of life-extension and outage projects mentioned above, and growth investments.

Second quarter adjusted EBITDA(1) increased for the reasons noted above.

Second quarter GAAP EPS increased as higher operating income, higher other income and a lower tax rate, were partially offset by higher interest expense. Non-GAAP EPS(1) increased as higher operating income, higher other income and a lower tax rate were partially offset by higher interest expense.

Second quarter operating cash flow increased driven by higher net income, working capital management, and timing of awards. Capital expenditures increased slightly due to timing of select growth investments, including the previously announced expansion of the Cambridge manufacturing plant that supports the commercial nuclear market.

BWXT paid $23.1 million, or $0.25 per common share, to shareholders in the second quarter of 2025. On July 30, 2025, the BWXT Board of Directors declared a quarterly cash dividend of $0.25 per common share payable on September 5, 2025, to shareholders of record on August 18, 2025.

BWXT raised its 2025 guidance for revenue, adjusted EBITDA(1) and non-GAAP EPS(1), and increased the low-end its free cash flow guidance.

Additional information can be found in the second quarter 2025 earnings call presentation on the BWXT investor relations website at www.bwxt.com/investors. The Company does not provide GAAP guidance because it is unable to reliably forecast most of the items that are excluded from GAAP to calculate non-GAAP results. These items could cause GAAP results to differ materially from non-GAAP results.

BWXT uses and makes reference to adjusted EBITDA, non-GAAP EPS, free cash flow and free cash flow conversion, which are not recognized measures under GAAP. BWXT is providing these non-GAAP measures to supplement the results provided in accordance with GAAP and it should not be considered superior to, or as a substitute for, the comparable GAAP measures. BWXT believes the non-GAAP measures provide meaningful insight and transparency into the Company’s operational performance and provides these measures to investors to help facilitate comparisons of operating results with prior periods and to assist them in understanding BWXT's ongoing operations. Definitions for the non-GAAP measures are provided below and reconciliations are detailed in Exhibit 1, except that reconciliations of forward-looking GAAP measures are not provided because the company is unable to reliably forecast most of the items that are excluded from GAAP to calculate non-GAAP results. Other companies may define these measures differently or may utilize different non-GAAP measures, thus impacting comparability.

Non-GAAP Earnings Per Share (EPS) is calculated using GAAP EPS less the non-operational tax effected per share impact of pension & OPEB mark-to-market gains or losses and other one-time items, such as restructuring, transformation, acquisition-related costs, and acquisition-related amortization.

Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) is calculated using non-GAAP net income, plus provision for income taxes, less other – net, less interest income, plus interest expense, plus depreciation and amortization.

Adjusted pre-tax income is non-GAAP income before provision for income taxes.

Free Cash Flow (FCF) is calculated using net income to derive net cash provided by (used in) operating activities less purchases of property, plant and equipment.

Free Cash Flow conversion is free cash flow divided by net income.

Our GAAP financial results detailed in Exhibit 1 have been adjusted for the following items:

Restructuring and Transformation Costs: Restructuring and transformation costs include restructuring charges as well as costs associated with our efforts to optimize underlying business processes through investments in information technology, process improvements and the implementation of strategic actions and initiatives which we deem to be incremental and non-recurring in nature.

Acquisition-related Costs: Acquisition-related costs relate to third-party professional service costs and one-time incremental costs associated with due diligence activities and efforts to integrate the acquired business with our legacy operations.
