Castellum Subsidiary Adds IT Professional Services to GSA Contract for Expanded Opportunities

Castellum Inc. (NYSE:CTM) is one of the Reddit stocks that will go to the moon. On October 14, Castellum announced a strategic addition to its contract portfolio. Its subsidiary, Specialty Systems Inc./SSI, successfully added Special Item Number/SIN 54151S to a new General Services Administratio/GSA Multiple Award Schedule/MAS contract.

The addition of SIN 54151S is significant because it now enables SSI to compete for contracts specifically related to information technology professional services. The contract update is part of Castellum’s strategy to expand its competitive reach.

According to Drew Merriman, COO of Castellum, this step allows the company to compete for more full-and-open opportunities as a large business while still maintaining access to small business set-asides through its mentor-protégé joint ventures. Specifically, the inclusion of SIN 54151S makes it a prerequisite for Castellum to onboard its joint venture with SSI’s protégé, Epic Systems Inc., to the GSA MAS contract since both companies now hold contracts under the 54151S SIN.

Castellum Inc. (NYSE:CTM) provides services in the areas of cybersecurity, information technology, electronic & information warfare, and information operations.
