Castellum, Inc. (CTM) · Nov 6, 2026 · Earnings
Miss — Revenue $14.7M vs ~$15.0M consensus; EPS $(0.01) vs ~$0.00
Castellum’s Q3 earnings missed modestly: revenue came in below consensus and adjusted EBITDA fell sharply despite a larger backlog and pipeline.
Castellum is in the scale-up phase of a federal defense technology-services platform: it is executing large Navy and defense contracts, investing ahead of revenue in business development, and pursuing acquisitions to add capabilities and scale. Its prior story already emphasized record 2026 revenue, a growing contract base, and deliberately front-loaded spending on growth and M&A.
The quarter missed a modest market bar. Q3 revenue of $14.7 million was slightly below the published estimate of roughly $15.0 million, while EPS was a $0.01 loss against expectations around breakeven. That makes this a genuine earnings miss, though not a large one. The filing itself shows revenue was essentially flat year over year, while gross profit fell and operating expenses rose.
| Metric | Q3 2026 | Q3 2025 | Consensus |
|---|---|---|---|
| Revenue (Financial Highlights) | $14.7M (+0.6%) | $14.6M | $15.0M |
| GAAP EPS (Financial Highlights) | $(0.01) | $0.00 | $0.00 |
| Gross profit (Financial Highlights) | $5.3M (-3.5%) | $5.5M | |
| Adjusted EBITDA (EBITDA reconciliation) | $0.6M (-46.7%) | $1.1M |
The bigger issue is profitability, not demand. Nine-month revenue grew 6% to $42.9 million, but gross profit was flat and adjusted EBITDA fell to about $1.0 million from $1.8 million. Management attributes the pressure to a higher mix of lower-margin subcontractor work and planned spending on business development and acquisitions; that explanation was already part of the standing story, so the decline is less surprising than the weak conversion of revenue into earnings.
The growth platform did advance, but mostly in future-facing measures. Castellum added a $32.8 million NAVAIR contract modification, reported $254.5 million of scheduled backlog, and expanded its qualified opportunity pipeline to approximately $1.66 billion. Those figures support future revenue visibility, but they do not yet offset the current-period margin deterioration; backlog and pipeline still have to convert into funded, profitable work.
The balance sheet gives the company room to keep investing. Castellum ended the period with $15.7 million of cash, $24.5 million of cash and accounts receivable combined, and no outstanding debt. That limits near-term financing pressure and keeps the acquisition strategy viable, but it also means the next proof point is whether those investments produce better-margin growth rather than simply more revenue.
Bottom line: The quarter modestly weakens Castellum’s execution story: revenue growth is intact, but earnings conversion is moving the wrong way and missed a low bar. The backlog, pipeline, and debt-free balance sheet keep the longer-term expansion plan alive, but the business now needs profitable growth—not just more contracts—to validate it.
