Castellum Inc. (CTM)
🔔 Watch stock
On Reddit, the ticker CTM surfaces now and then — a defense contractor worth about $61 million, its stock trading for pocket change. We read what Castellum, Inc. itself reported to the U.S. securities regulator — in the annual report (10-K) for 2025 and the quarterly report (10-Q) through March 2026: a genuine revenue record of $52.9 million, a balance sheet nearly free of debt, a quarterly loss shrunk to $0.35 million — but also 73 percent of revenue from three customers, effectively a single payer called the U.S. government, and a share count that nearly doubled within two years. Not investment advice — just the per-share price tag and the share count, added up honestly.

NeutralGeprüft am 15.07.2026 gegen den Geschäftsbericht (10-K) für 2025 (eingereicht 09.03.2026), den Geschäftsbericht (10-K) für 2024 (eingereicht 11.03.2025) und die vier jüngsten Quartalsberichte (10-Q, zuletzt zum 31.03.2026): In den ausgewerteten SEC-Filings von Castellum findet sich kein wesentlicher KI-Bezug — die Volltextsuche nach „artificial intelligence“, „machine learning“, „generative“, „large language“, „LLM“ und „AI“ liefert in allen sechs Dokumenten null Treffer. Das Leistungsportfolio wird als Cybersecurity, Electronic Warfare, Information Warfare, Systemmodernisierung und Informationsoperationen für US-Verteidigungs- und Bundesbehörden beschrieben (Item 1 „Business“ des 10-K für 2025) — ohne KI-Produkte, ohne dokumentierten operativen KI-Einsatz und ohne KI-spezifisches Geschäftsrisiko; auch der Risikokatalog (Item 1A bzw. die Forward-Looking-Hinweise des 10-Q) nennt Budget-, Konzentrations- und Verwässerungsrisiken, aber keine KI. Nach dem Kriterienkatalog dokumentierter Negativ-Befund → „neutral“.

- EPS (Earnings Per Share):
- Quarterly profit divided by the total share count — how much of the profit works out to a single share.
- YoY (Year over Year):
- Change versus the same quarter a year ago — this is how you compare without seasonal distortion (e.g. the holiday shopping season).
- Sales:
- All revenue for the quarter, before any costs are deducted — the top line of the income statement.
- Net Margin:
- What percentage of sales is left over as profit in the end. Negative means the company is posting a loss.
- OCF (Operating Cash Flow):
- The cash that actually flows into the till from the core business during the quarter — harder to dress up than book profit.
- FCF (Free Cash Flow):
- Operating cash flow minus capital expenditures — the money that's genuinely free to use, say for paying down debt, buybacks, or dividends.
Assessment: Opportunities & Risks
A sought-after niche — cybersecurity, electronic warfare and IT modernization for the Pentagon — with a genuine personnel moat: 97 percent of the 244 employees hold security clearances (December 31, 2025). But the kit of seven acquisitions since 2019 had missteps (a $6.92 million goodwill impairment in 2023, MFSI sold in 2024), and the company remains a minnow among whales.
2025 revenue up 18.1 percent to a record $52.87 million, Q1 2026 up 23 percent; the net loss shrank from $17.80 million (2023) to $2.40 million (2025) and $0.35 million in the first quarter of 2026 — the NAVAIR contract ($103.3 million, March 2024) carries, and the interest burden is repaid (annual and quarterly reports).
Three customers = 73 percent of revenue and 73 percent of receivables (2025; 2024: 47 percent), "substantially all" revenue from U.S. government entities; the quarterly report as of March 31, 2026 names the DOGE office and contract terminations for convenience as risks by name.
The share count nearly doubled from 47.7 to 94.6 million in two years (offerings 12/2024, 03/2025, 06/2025 plus warrants), with 3 billion shares authorized; the annual report itself warns of "substantial dilution" from future financings. Revenue per share fell despite the record year.
$15.77 million of cash against $5.68 million of total liabilities (March 31, 2026), no bank debt, the last related-party note repaid, $35.75 million of stockholders' equity (December 31, 2025) — unusually tidy for a nano-cap; bought, however, through the dilution.
A price-to-sales ratio around 1.2 (market value about $61 million, July 15, 2026), roughly 0.9 times revenue net of cash — neither a bargain nor a fantasy price. A pocket-change share price, thin trading and wild swings remain structural; the $817 million pipeline and the $250 million multiple-award contract (June 2026) are opportunities, not revenue.
Castellum is no empty penny ticker: record revenue in 2025, a quarterly loss melted down to $0.35 million, a balance sheet nearly free of debt, and a niche with priority in the defense budget. But the road there was paid for with a near-doubling of the share count, three customers carry 73 percent of revenue, the only payer is the U.S. government — and its cost-cutting office is named in the risk list. The pocket-change price is neither an argument nor a counterargument: it measures the slices, not the cake. Not investment advice.
