VIENNA, Va., May 08, 2026 (GLOBE NEWSWIRE) -- Castellum, Inc. (NYSE-American: CTM) (“Castellum” “CTM”, “we” or the “Company”), a cybersecurity, electronic warfare, and software services company focused on the federal government, today announced its financial results for the three-month period (“Q1”) ended March 31, 2026.

Q1 2026 Financial Highlights

• Revenues of $14.3 million, up 23% as compared to $11.7 million in Q1 2025.
• Gross profit of $5.1 million, up 11% as compared to $4.6 million in Q1 2025.
• Adjusted EBITDA* was $0.4 million, compared to $0.08 million in Q1 2025.
• Net loss was $0.4 million (or $0.00 per basic and diluted share), improved from a net loss of $1.2 million (or $0.01 per basic and diluted share) in Q1 2025.
• Cash and cash equivalents as of March 31, 2026 was $15.8 million, as compared to $14.9 million at December 31, 2025.

See the reconciliation to non-GAAP Adjusted EBITDA chart below.

Q1 2026 Operational Highlights

• Total backlog reached a record $273.3 million as of March 31, 2026, up from $265 million at December 31, 2025.
• Qualified pipeline totaled $938 million as of March 31, 2026, up from $817 million at December 31, 2025, reflecting a substantial increase in identified opportunities.

Glen Ives, President and Chief Executive Officer of Castellum, commented, “Our strong Q1 2026 results reflect the momentum we built throughout a standout 2025, when we secured over $219 million in contracts across three major, long‑term prime wins and deepened our relationships with the U.S. Navy and other key federal customers. The 23% revenue increase for Q1 2026 was driven by production ramp‑up of these new contract wins. We ended the quarter with a record backlog of approximately $273 million, which provides us with multi‑year revenue visibility. We currently expect to recognize approximately 16% of this backlog over the next 12 months and approximately 49% over the next 24 months, with the remainder recognized thereafter. Similarly, the pipeline of qualified opportunities continues to increase, and we had $938 million in identified opportunities at quarter-end, which is a testament of the strength of our strategy and the competitiveness of our offerings for complex, mission‑critical programs in cybersecurity, electronic warfare, and advanced engineering.”

David Bell, Chief Financial Officer of Castellum, noted, “Q1 2026 was our best first quarter ever and second best of any quarter on record in terms of revenue and delivered a significantly improved bottom line. Strong year-over-year revenue growth, combined with our ongoing efforts to improve production efficiencies, resulted in increased gross profit for the quarter, while our gross margin of 35.4% was somewhat affected by changes in contract mix and type. During the quarter, we also completed the payoff of our remaining long-term debt, which lowered our interest expense substantially. We ended the period with a debt‑free balance sheet and $15.8 million in cash, which give us the flexibility to invest in growth initiatives while maintaining a solid financial profile.”

Discussing the go-forward strategy, Mr. Ives concluded, “We have entered Phase 3 of Castellum’s evolution, and our priorities are clear. We are focused on building on our strong organic growth momentum, fully leveraging our new CMMC Level 2 C3PAO certification as a key competitive differentiator in the DoD market, federal cyber and mission‑critical programs, and selectively exploring compelling M&A opportunities that meet our criteria. In parallel, we will continue investing in mission-critical technologies and capabilities which will enable us to further expand our markets, client base, and capture emerging growth opportunities. As we progress through 2026, we remain focused on disciplined execution to position Castellum for sustainable, long-term growth and enhanced shareholder value.”

Non-GAAP Financial Measures and Key Performance Metrics

This press release contains Non-GAAP Adjusted EBITDA, which is a Non-GAAP financial measure that is used by management to measure the Company's operating performance. 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.
