(NYSE: KBR) today announced its first quarter fiscal 2025 results. “KBR delivered strong performance in the first quarter, driving higher year-over-year revenues, margin, earnings, and cash flow,” said Stuart Bradie, President and CEO. “We remain focused on consistently executing well on our major projects and controlling what is within our control. We are benefiting from ongoing robust LNG demand, with increased Plaquemines activity yielding greater profit and cash flow. HomeSafe move volumes continued to ramp up during the quarter with rising customer satisfaction scores. Additionally, we are maintaining strong bid volumes and seeing continuing momentum with strategic new contract wins.” Mr. Bradie continued, “Although we have not seen any material program or contract cuts in our U.S. government base, the environment remains volatile, and we remain agile to meet changing customer demand dynamics. We are realizing the benefits of our previously announced segment realignment plan and managing our indirect costs during this period of heightened uncertainty. We remain bullish on KBR's long-term outlook. In the first quarter, we executed one of the largest share buybacks in the company's history, acting on the board-authorized $750 million repurchase program.” Mr. Bradie concluded, “We have a strong, resilient portfolio, primarily comprising multi-year projects and programs, with multiple growth pathways as we operate across diversified geographies and end markets. Our focus is on executing our strategy, including continuing to partner closely with our customers to solve their most challenging problems.” 1 As used throughout this release, book-to-bill and bookings and options exclude long-term UK PFIs and the Plaquemines LNG project. 2 As used throughout this earnings release, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted earnings per share, and Operating cash conversion are non-GAAP financial measures.

Revenues were $2.1 billion, up 13% or $237 million, primarily driven by growth in Defense & Intel, fueled by the LinQuest acquisition, and in Readiness & Sustainment due to moves associated with HomeSafe in Mission Technology Solutions and increasing demand in Sustainable Technology Solutions. Operating income was $195 million, up 17% or $29 million, primarily due to increases in Gross profit and Equity in earnings of unconsolidated affiliates due to strong project execution on an LNG project, partially offset by increases in Selling, general and administrative expenses. Net income attributable to KBR was $116 million, up 25% or $23 million, primarily due to the increase in Operating income noted above and flat below the line expenses. Diluted earnings per share were $0.88, up 28% or $0.19, primarily due to higher Net income attributable to KBR noted above and lower diluted weighted average common shares outstanding due to open market share repurchases. Adjusted EBITDA 2 was $243 million, up 17% or $36 million, primarily due to the increase in Operating income noted above. Adjusted EBITDA 2 margin was 11.8%, up from the prior year due to strong operating performance in the current year period.

The company has provided the non-GAAP financial information presented in the press release as information supplemental and in addition to the financial measures presented in the press release that are calculated and presented in accordance with GAAP. Such non-GAAP financial measures should not be considered superior to, as a substitute for or alternative to, and should be considered in conjunction with, the GAAP financial measures presented in the press release. The non-GAAP financial measures in the press release may differ from similar measures used by other companies. Adjusted EBITDA We evaluate performance based on Adjusted EBITDA and Adjusted EBITDA margin. Adjusted EBITDA is defined as Net income (loss) attributable to KBR, plus Interest expense; Other non-operating expense (income); Provision for income taxes; Depreciation and amortization; and certain discrete items as identified by Management to be non-recurring in nature as set forth below. Adjusted EBITDA can also be defined as Operating income less Net income attributable to noncontrolling interests; plus Depreciation and amortization; and certain discrete items as identified by Management to be non-recurring in nature as set forth below. Adjusted EBITDA margin is calculated as Adjusted EBITDA divided by Revenues. Adjusted EBITDA and Adjusted EBITDA margin for each of the three month periods ended April 4, 2025 and March 29, 2024 are considered non-GAAP financial measures under SEC rules because Adjusted EBITDA excludes certain amounts included in the calculation of Net income (loss) attributable to KBR in accordance with GAAP for such periods. Management believes Adjusted EBITDA and Adjusted EBITDA margin afford investors a view of what management considers KBR's core performance for each of the three month periods ended April 4, 2025 and March 29, 2024 and also affords investors the ability to make a more informed assessment of such core performance for the comparable periods.

The most directly comparable financial measure calculated in accordance with GAAP is Diluted EPS for the same periods. Management believes that Adjusted EPS affords investors a view of what management considers KBR's core earnings performance for each of the three month periods ended April 4, 2025 and March 29, 2024 and also affords investors the ability to make a more informed assessment of such core earnings performance for the comparable periods. Three Months Ended April 4, March 29, 2025 2024 Diluted EPS $ 0.88 $ 0.69 Adjustments • Amortization related to acquisitions 0.07 0.04 • Ichthys commercial dispute cost — 0.03 • Acquisition, integration and other 0.03 0.01 Adjusted EPS $ 0.98 $ 0.77 Diluted weighted average common shares outstanding 132 135 Adjusted weighted average common shares outstanding 132 135 11 Operating Cash Conversion Operating cash conversion is considered a non-GAAP financial measure under SEC rules. Operating cash conversion is calculated as Operating cash flows divided by Adjusted weighted average common shares outstanding, which is then divided by Adjusted earnings per share. Management believes that Operating cash conversion affords investors a view of what management considers KBR's core operating cash flow performance for each of the three month periods ended April 4, 2025 and March 29, 2024 and also afford investors the ability to make a more informed assessment of such core operating cash generation performance.
