Castellum is a sub-dollar defense/national-security IT services roll-up (seven acquisitions since 2019) that is finally showing operating leverage. FY2025 revenue of $52.9M grew 18.1%, breaking out of three years of stagnation ($42.2M→$45.2M→$44.8M), and the net loss narrowed dramatically to -$2.40M from -$9.98M (+76%), with operating loss down to -$2.81M and diluted EPS at just -$0.03. The balance sheet is genuinely clean: $14.9M cash, only $6.15M total liabilities, a 0.17x liabilities/equity ratio, and $35.8M of equity. At a $68.4M market cap and 1.3x sales, the stock is not expensive for a government-services name approaching breakeven with a defense tailwind behind it.

The problem is how that clean balance sheet was built — repeated, deeply dilutive equity raises. The MD&A details registered direct offerings at $0.32, $0.38, and lower, plus exercised warrants, and shares outstanding rose 17.7% to 94.6M; equity's 77% jump is funded by stockholders, not earnings (accumulated deficit is -$56.6M). The S-3 shelf ($10M capacity) and remaining Regular Warrants leave a standing dilution overhang. Worse, the improving income statement isn't yet converting to cash: operating cash flow swung to -$1.95M (down 273.9%), and gross profit grew only 6% against 18% revenue growth, signaling margin compression as lower-quality contract revenue mixes in (gross margin 36.6%, but the incremental work is dilutive to it).
