Lynchburg, VA – August 5, 2024 - BWX Technologies, Inc. (NYSE: BWXT) ("BWXT", "we", "us" or the "Company") reported second quarter 2024 results. A reconciliation of non-GAAP results are detailed in Exhibit 1.

“Second quarter results were ahead of our expectations driven by strong organic growth and crisp execution across our business lines,” said Rex. D Geveden. “Our solid year-to-date performance provides us the confidence to raise the lower end of our 2024 non-GAAP EPS guidance.”

“In recent months there have been multiple important developments supporting our nuclear markets, including passage of the ADVANCE Act, federal and state legislation supporting small modular reactor development and the Army and Defense Innovation Unit’s acquisition plans for microreactors at remote military bases, all of which have been complemented by broad-based support from private industry,” continued Geveden. “These developments demonstrate the increasing appetite for nuclear solutions across the global security, clean energy, and medical markets, ultimately driving new and exciting opportunities for BWXT.”

“Overall, we had a solid first half both financially and strategically and we continue to see favorable demand momentum in our end-markets,” continued Geveden. “Based on our year-to-date performance and anticipated progress on key contracts during the second half of the year, we are narrowing our 2024 non-GAAP EPS guidance to $3.10- $3.20.”

(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; Share Repurchases = Repurchases of Common Stock; 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, microreactors and special materials processing. The Commercial Operations increase was driven by higher revenue associated with commercial nuclear field services, components, and fuel and fuel handling systems as well as higher medical sales.

Operating Income and Adjusted EBITDA(1)

Second quarter operating income increased in both segments. The Government Operations increase was mainly driven by higher revenue, which was partially offset by investments in new initiatives. The Commercial Operations increase was primarily driven by higher revenue and a shift in product and services mix.

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

Second quarter GAAP EPS increased due to higher operating income, lower interest expense and a lower effective tax rate compared to second quarter 2023. The lower tax rate was mainly driven by Canadian legislation that provides for a lower statutory tax rate for clean energy, including nuclear, manufacturers. Non-GAAP EPS(1) increased driven by the items noted above.

Second quarter operating cash flow decreased as higher net income was more than offset by greater working capital needs due to contract timing. Capital expenditures were lower due to timing of select growth investments.

BWXT paid $22.0 million, or $0.24 per common share, to shareholders in the second quarter of 2024. On August 1, 2024, the BWXT Board of Directors declared a quarterly cash dividend of $0.24 per common share payable on September 5, 2024, to shareholders of record on August 16, 2024.

BWXT reaffirmed its 2024 guidance for Revenue, Adjusted EBITDA(1), and Free Cash Flow(1) and narrowed its guidance range for Non-GAAP EPS(1).

Additional information can be found in the second quarter 2024 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, and acquisition-related costs.

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 efforts to integrate the acquired business with our legacy operations.

One-Time Tax Benefit: During the second quarter of 2024, a change in Canadian tax legislation went into effect that provides qualifying nuclear manufacturers with a temporary reduction of the Canadian federal tax rate. This change in legislation resulted in a one-time revaluation of our Canadian net deferred tax liabilities.

BWXT cautions that this release contains forward-looking statements, including, without limitation, statements relating to backlog, to the extent they may be viewed as an indicator of future revenues; our plans and expectations for each of our reportable segments, including growth opportunities and the expectations, timing and revenue of our strategic initiatives, such as medical radioisotopes, SMR components and recent acquisitions; disruptions to our supply chain and/or operations, changes in government regulations and other factors; and our expectations and guidance for 2024 and beyond.

These forward-looking statements are based on management’s current expectations and involve a number of risks and uncertainties, including, among other things, our ability to execute contracts in backlog; federal budget uncertainty, the risk of future budget cuts, the impact of continuing resolution funding mechanisms and the debt ceiling, the potential for government shutdowns and changing funding and acquisition priorities; the demand for and competitiveness of nuclear products and services; capital priorities of power generating utilities and other customers; the timing of technology development, regulatory approvals and automation of production; the receipt and/or timing of government approvals; the potential recurrence of subsequent waves or strains of COVID-19 or similar diseases; labor market challenges, including employee retention and recruitment; adverse changes in the industries in which we operate; and delays, changes or termination of contracts in backlog. If one or more of these risks or other risks materialize, actual results may vary materially from those expressed. For a more complete discussion of these and other risk factors, see BWXT’s filings with the Securities and Exchange Commission, including our annual report on Form 10-K for the year ended December 31, 2023 and subsequent Form 10-Q filings.
