Investor Day 2026 November 11 Focused on what the future demands
32026 KBR Investor Day Welcome Rachael Goldwait Vice President, Investor Relations
4 On September 24, 2025, KBR, Inc. (“KBR”) announced its strategic intention to spin off its Mission Technology Solutions segment to create a separate, publicly traded company, Trinzic, Inc. (“Trinzic”). The spin-off is currently targeted to be completed in January 2027, subject to final approval by KBR's board of directors and other customary conditions. References in this presentation to “KBR” or “we” refer to the KBR business following the completion of the spin-off, comprising KBR's Sustainable Technology Solutions segment. Forward-Looking Statements This presentation contains forward-looking statements regarding our plans, including the proposed separation of Trinzic into an independent, publicly traded company, and our objectives, goals, strategies, investments, capital deployment, risk profile, program activity, backlog information, returns, capital requirements, future events, future financial performance, future demand expectations and other information that is not historical. When used in this presentation, the words “estimates,” “expects,” “anticipates,” “potential,” “projects,” “plans,” “intends,” “believes,” “forecasts,” “targets” or future or conditional verbs such as “will,” “should,” “could” or “may,” and variations of such words or similar expressions are intended to identify forward-looking statements. Because forward-looking statements relate to the future, they are subject to inherent risks, uncertainties and other factors that are difficult to predict, and which could cause actual results to differ materially from the forward-looking statements contained in this presentation. Our most recently filed Annual Report on Form 10-K, any subsequent Form 10-Qs and 8-Ks and other U.S. Securities and Exchange Commission filings discuss some of the important risk factors that the company has identified that may affect its business, results of operations and financial condition. The medium-term targets presented herein reflect our current objectives and do not constitute guidance. Forward-looking statements, including these targets, are not guarantees of future performance, and our actual results and future developments may differ materially and adversely from those expressed or implied by such statements. We caution you not to place undue reliance on the forward-looking statements included in this presentation, which speak only as of the date hereof. We disclaim any intent or obligation, except as required by law, to revise or update publicly any forward-looking statements for any reason. Non-GAAP Financial Information This presentation includes certain non-GAAP financial measures. Because not all companies calculate non-GAAP financial measures identically (or at all), the presentations herein may not be comparable to other similarly titled measures used by other companies. Further, such non-GAAP financial information should not be considered superior to, as a substitute for or as an alternative to the historical financial information of the company, if any, prepared in accordance with GAAP. Please refer to the Appendix for definitions and reconciliations of non-GAAP financial information to the nearest GAAP measure. The company does not provide reconciliations of non-GAAP financial information to the most comparable GAAP financial measure on a forward-looking basis because the company is unable to predict with reasonable certainty the ultimate outcome of legal proceedings, unusual gains and losses, capital expenditures and acquisition-related expenses without unreasonable effort, which could be material to the company’s results computed in accordance with GAAP.

62 Footnotes 2026 KBR Investor Day 1 Adjusted EBITDA and adjusted EBITDA margin are non-GAAP financial measures. Adjusted EBITDA is defined as net income (loss) attributable to KBR, adjusted to exclude net (income) loss from discontinued operations, net of tax, and net income (loss) attributable to noncontrolling interest included in discontinued operations. Further adjustments add back interest expense, other non- operating expense (income), provision for income taxes, depreciation and amortization, and certain discrete items that have been identified by Management as not being reflective of the core operating performance of our business. Certain discrete items include spin-off, acquisition and integration costs, non-cash loss (gain) on legal entity realization, Ichthys commercial dispute costs, and provisions related to exit from Russian commercial projects. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by Revenues. Management believes these measures provide investors with useful information regarding KBR’s core performance. For post-spin KBR, Adjusted EBITDA also excludes net periodic pension benefit as a discrete item. All references to 2026E reflect illustrative implied segment adjusted EBITDA based on consolidated KBR 2026E guidance. 2 Adjusted EBITDA excluding LNG JV excludes the earnings contribution from the Plaquemines LNG joint venture. 3 Repeat business represents revenue from customers for whom KBR has previously performed work, as a percentage of revenue for the stated period. 4 Serviceable Addressable Market (SAM) and estimated global market CAGR reflect KBR’s interpretation and synthesis of external sources. 5 Organic revenue CAGR reflects compound annual revenue growth from 2026E to 2029E and excludes future capital deployment and megaprojects exceeding $1 billion of KBR scope. 6 Recurring JV EBITDA represents the earnings contribution from Brown & Root Industrial Services (BRIS) and other recurring joint ventures included in Adjusted EBITDA, excluding LNG JV. 7 Free cash flow and free cash flow conversion are non-GAAP financial measures. Free cash flow is calculated as cash flows provided by operating activities less capital expenditures. Free cash flow conversion is calculated as free cash flow divided by adjusted net income. Management believes these measures provide investors with useful information regarding KBR’s cash generation and ability to convert earnings into cash. 8 Net leverage is defined as gross debt less cash and cash equivalents, divided by trailing-twelve-month adjusted EBITDA. 9 Qualified pipeline reflects identified potential customer opportunities assessed by KBR. Pipeline is not backlog and does not guarantee awards or future revenue. 10 Book-to-bill (BTB) is bookings divided by consolidated revenue for the same period. Bookings and revenue reflect consolidated results only and exclude the proportionate share of unconsolidated joint ventures. 11 Backlog represents the value of work for which KBR has been selected and that is expected to be completed by consolidated subsidiaries, plus KBR’s proportionate share of work expected to be performed by unconsolidated joint ventures.

Accordingly, the Company reconciles STS adjusted EBITDA to segment operating income, which management believes is the most directly comparable measure of segment profitability. The company does not provide reconciliations of non-GAAP financial information to the most comparable GAAP financial measure on a forward-looking basis because the company is unable to predict with reasonable certainty the ultimate outcome of legal proceedings, unusual gains and losses, capital expenditures and acquisition-related expenses without unreasonable effort, which could be material to the company’s results computed in accordance with GAAP.
