Castellum, Inc. files its annual report describing a government-focused technology business providing cybersecurity, IT, C4ISR, engineering, mission support, and IT services, largely to U.S. defense and civilian agencies. The company pursues growth through acquisitions and organic expansion, supported by an $817 million qualified opportunity pipeline as of December 31, 2025.
Castellum’s revenue is highly concentrated: in 2025 its top three contracts generated $28,341,498, or 54% of revenue, mainly from Navy and DoD cyber and engineering work. The report highlights heavy dependence on U.S. government budgets and regulations, an accumulated deficit of $56,588,218 as of December 31, 2025, ongoing net losses, and the need for additional capital, which may dilute shareholders. It also discloses significant potential dilution from preferred stock, options, and warrants and outlines extensive regulatory, contracting, and political risks tied to federal funding and oversight.
Castellum, Inc. reported strong unaudited 2025 results with clear operational progress. Revenue for 2025 rose to $52.9 million, up $8.1 million or 15.2% from 2024, and management notes this growth is entirely organic following its last acquisition in 2023.
The company’s profitability metrics improved meaningfully. Operating loss narrowed to $2.8 million from $7.2 million, while net loss to common shareholders improved to $2.5 million from $10.1 million, reflecting better contract wins and cost discipline. Non-GAAP Adjusted EBITDA increased to $1.0 million from $0.8 million, after adding back depreciation, amortization, stock-based compensation, and prior-year non-recurring charges.
The balance sheet strengthened as total cash grew by $2.6 million to $14.9 million as of December 31, 2025, supported by financing activities and the strategic use of cash to reduce outstanding debt from $10.7 million a year earlier. Management highlights improved cash-to-debt metrics and a shift from other expense of $2.7 million in 2024 to other income of $0.6 million in 2025. Leadership describes ongoing contract wins, increased business development investment, and renewed M&A activity as they prepare for further organic and acquisition-driven growth.

The company highlights three major prime contract wins over the past year totaling just over $219 million in value, each running about five years and supporting U.S. Navy missions. Leadership describes a shift from an acquisition-driven "Phase 1" to an organic growth-focused "Phase 2," and now a "Phase 3" strategy that combines continued organic growth with at least one accretive acquisition targeted within the next 12 months.
