(CTM) reported that its subsidiary Global Technology and Management Resources, Inc. received a $32.8 million modification to its existing cost-plus-fixed-fee order supporting the U.S. Navy’s NAVAIR PMA-290 Special Missions. This expands the order’s scope and raises the total contract ceiling to $136.2 million, described as the largest prime contract win in the company’s history. Approximately $1.1 million of the modification is currently funded, with that work expected to run through March 2027, while the remaining ceiling increase depends on future tasking, funding availability, and other government-contracting conditions.
Castellum, Inc. reported Q2 2026 revenue of $13.9 million, essentially flat with Q2 2025, and gross profit of $4.7 million, or 34% of revenue. Q2 Adjusted EBITDA was $0.03 million, while net loss widened to $1.1 million (or $(0.01) per share).
For the first half of 2026, revenue rose 10% to $28.2 million and gross profit increased to $9.8 million. Net loss to common shareholders improved slightly to $1.4 million (or $(0.02) per share), and Adjusted EBITDA was $0.4 million. The company ended June 30, 2026 with a debt‑free balance sheet and $16.9 million in cash.
Backlog totaled $271.7 million and the qualified pipeline $953.5 million. Castellum currently expects to recognize about 16% of backlog over the next 12 months and 48% over 24 months and states it is on track for record full‑year 2026 revenue.

Castellum, Inc. reported higher six‑month 2026 revenue of $28.2 million, up 10% from the prior‑year period, while remaining unprofitable with a six‑month net loss to common shareholders of $1.43 million. Second‑quarter revenue was $13.9 million, down 1% year over year, and the quarterly net loss widened to $1.05 million as higher subcontractor usage and operating costs pressured margins.
Cash increased to $16.9 million at June 30, 2026, with total liabilities of $5.9 million after repaying a $400,000 related‑party note and closing a prior revolving credit facility. A large contract backlog of $271.7 million and an estimated $953.5 million opportunity pipeline underscore revenue visibility, but three U.S. government customers accounted for 81% of revenue and 75% of receivables, leaving results highly dependent on federal budgets, continuing resolutions, and procurement timing.
