AI Analysis

AI-generated, general educational analysis — not personal investment advice.

I look for durable earning power and a margin of safety. Castellum sells intelligence analysis, software engineering, cybersecurity, data analytics, and related technology services. It is a small 244-employee firm, and nothing in the record suggests a wide moat. In fiscal 2023, the year ended 2023-12-31, revenue was $45.2M and net income was -$17.8M, or EPS -$0.38. In fiscal 2024, the year ended 2024-12-31, revenue was $44.8M and net income was -$10.0M, or EPS -$0.18. In fiscal 2025, the year ended 2025-12-31, revenue was $52.9M and net income was -$2.4M, or EPS -$0.03. Losses narrowed and revenue rose, but the company still has not earned a full-year profit. In fiscal Q2 2026, the quarter ended 2026-06-30, revenue was $13.9M and net income was -$1.0M, or EPS -$0.01; in fiscal Q1 2026, the quarter ended 2026-03-31, revenue was $14.3M and net income was -$351,274. Results swing. FairStock shows D/E of 0.03, trailing free cash flow of $2.6M, and FCF yield of 4.7% against the $55.9M market cap at the 2026-10-13 close. But its Piotroski F-score is 2/9, and the Lynch screen finds no category because of losses in each of the last four years. At $0.59, P/B is 1.55 and P/E is -19.67, per FairStock. Without sustainable profits, intrinsic value is guesswork. This is a speculative turnaround, not a Graham bargain.

In plain English: Castellum is a small technology services company with 244 employees that provides intelligence analysis, cybersecurity, software development, data analytics and related services. The business looks weak because it has lost money in each of the last four years, though the losses shrank and it recently generated some cash. At $0.59 a share, the price is not obviously cheap or expensive because there is still no steady profit to value it against.
