What Castellum, Inc. does
In the company’s own words
I cannot write the requested company overview because this document is not a 10-K filing. This is Exhibit 10.20, which is a Task Order (TO) N6833525F3003 issued under the SeaPort-NxG Multiple Award Contract (MAC) N00178-19-D-7718 by the U.S. Navy.
The document describes a government contract for professional engineering and technical support services to be performed at Naval Air Warfare Center Aircraft Division in Lakehurst, New Jersey. The contractor is identified as Specialty Systems Inc. (SSI), submitted as an affiliate to Global Technology Management Resources, Inc. (GTMR) under GTMR's prime SeaPort-NxG contract.
This task order covers a five-year period of performance (one base year plus four option years) beginning September 18, 2025, and includes Cost Plus Fixed Fee (CPFF) labor line items, cost reimbursement items for travel and materials, and deliverables specified in Contract Data Requirements Lists (CDRLs). The contract specifies various labor categories including engineers, analysts, programmers, and technical specialists to be performed at government and contractor sites.
Since this is a government contract document rather than a corporate 10-K filing, it does not contain the standard corporate information requested, such as company ticker symbol, website URL, total revenue, employee count, business segments, or other financial metrics typically found in SEC filings. The document is primarily administrative and contractual in nature, outlining terms, conditions, deliverables, payment procedures, and compliance requirements for the specified government services contract.
To obtain the requested company overview information, a copy of the actual 10-K filing for the relevant company would be required.
