S. Navy software modernization work . • Won a position on the U.S. Navy's $ 250.0 million LIIS CMDS Logistics IT MAC , providing a multi - year pipeline of task order opportunities to modernize naval maintenance and logistics IT systems . Glen Ives , President and Chief Executive Officer of Castellum , commented , " Revenue for the first six months of 2026 grew 10 % year over year to $ 28.2 million and gross profit increased to $ 9.8 million , driven by the continued ramp up of the major long - term prime contracts we won in 2025 , including the NAVAIR PMA - 290 Special Missions program and the NAWCAD Lakehurst MO & I award . This first half growth trajectory , combined with our total backlog of approximately $ 272 million and a qualified pipeline that continues to expand , gives us confidence that Castellum is on track to deliver record revenue for the full year 2026. Second quarter revenue was stable as compared to the prior year , reflecting gains from the ramp up of SSI's NAWCAD Lakehurst contract , partially offset by the expected wind down of certain contracts that contributed additional revenue in the second quarter of 2025. This revenue recognition timing factor is common in our industry . Additionally , we ended the quarter with a total backlog of approximately $ 272 million , which provides multi - year revenue visibility . We currently expect to recognize approximately 16 % of this backlog over the next 12 months and approximately 48 % over the next 24 months , with the remainder recognized thereafter . " David Bell , Chief Financial Officer of Castellum , noted , “ Our first half results reflect the strength of the underlying business , with revenue up 10 % and gross profit up 2 % year - over - year . Our second quarter gross margin of 34.0 % reflects a higher mix of subcontractor work , which typically carries a lower margin than direct labor , as well as the cost to complete the remaining work on the two firm - fixed - price contracts referenced above . As expected , EBITDA declined from prior periods , reflecting the planned 2026 investments in business development , investor relations , and acquisition activities . The economics of this work are inherently front - loaded . Whether we are pursuing a contract award , developing a product , or acquiring a business , certain costs are recognized well in advance of the revenue it is intended to generate . We are investing in Castellum's future , which means lower near - term EBITDA in exchange for a stronger https://investors.castellumus.com/news/news-details/2026/Castellum-Announces-Second-Quarter-and-First-Half-2026-Financial-Results/default.aspx 1/4

multi-year growth profile. Importantly, we funded the business entirely from operating cash flow during the first half, ending the period with a debt-free balance sheet and $16.9 million in cash, an increase of $2.0 million since year end, giving us the flexibility to invest in growth while maintaining a solid financial profile. With our first-half momentum and the investments we have made, we remain on pace for record full-year revenue.” Discussing the go-forward strategy, Mr. Ives concluded, “Our priorities in Phase 3 of Castellum's evolution remain unchanged, and the first half of 2026 was about putting the resources behind them. Based on the momentum we are seeing in our backlog, pipeline, and contract awards, we expect to deliver record revenue for the full year, and our focus for the second half is translating that growth into durable, higher-margin performance. Converting our backlog and pipeline into organic revenue growth. We expanded our business development capacity this year specifically to increase the volume and quality of opportunities we pursue, and that investment is already contributing to the growth we are seeing in the first half, which we expect to continue through the remainder of the year. Selectively pursuing M&A opportunities that meet our criteria. Our standards have not changed. We are looking for businesses that bring differentiated capability, contract vehicles or customer access we do not already have, and a valuation that is accretive to shareholders. We would rather pass on a transaction than force one. We continue to invest in mission-critical technologies and capabilities that expand both our addressable market and our client base. We are doing that work from a position of financial strength, funded internally and without leverage, which is what allows us to invest through the cycle rather than react to it. As we move through the second half of 2026, disciplined execution remains the priority. We believe that discipline, applied consistently, is what positions Castellum for sustainable long-term growth and enhanced shareholder value.” Conference Call Castellum will hold a conference call on Friday, August 7, 2026, at 10:00 am Eastern Time to discuss its second quarter 2026 financial results.

A reconciliation of this measure to the most directly comparable GAAP financial measure is contained herein. To the extent required, statements disclosing this measure's definition, utility, and purpose are also set forth herein. Definition: Adjusted EBITDA is a Non-GAAP measure, calculated as the Company’s earnings before (not including expenses related to) interest, taxes, depreciation, and amortization, also adjusted for other non-cash items such as stock-based compensation, and other non-recurring cash items, such as expenses for a one- time policy change. Utility and Purpose: The Company discloses Non-GAAP Adjusted EBITDA because this Non-GAAP measure is used by management to evaluate our business, measure its operating performance, and make strategic decisions. We believe Non-GAAP Adjusted EBITDA is useful for investors and others in understanding and evaluating our operating results in the same manner as its management. However, Non-GAAP Adjusted EBITDA is not a financial measure calculated in accordance with GAAP and should not be considered as a substitute for GAAP operating loss or any other operating performance measure calculated in accordance with GAAP. Using this Non-GAAP measure to analyze our business would have material limitations because the calculations are based on the subjective determination of management regarding the nature and classification of events and circumstances that investors may find significant. In addition, although other companies in our industry may report a measure titled Non-GAAP Adjusted EBITDA, this measure may be calculated differently from how we calculate this Non-GAAP financial measure, which reduces its overall usefulness as a comparative measure. Because of these inherent limitations, you should consider Non-GAAP Adjusted EBITDA alongside other financial performance measures, including net loss and our other financial results presented in accordance with GAAP.
