Micromem Technologies Inc. Update on Wearable Sensing Platform for Defence and
Security Application Evaluation
Toronto, Ontario and New York, New York, June 23, 2026 - Micromem Technologies Inc. ("Micromem" or the "Company") (CSE: MRM) (OTCQB: MMTIF) is pleased to provide an update following recent meetings with representatives of the Department of National Defence ("DND").
The Company has now completed its initial cost analysis and engineering review of the wearable unit prototype. Micromem is pleased to report that the current design has achieved the targeted cost objectives established for the program while maintaining the required functionality and performance specifications. The criteria established contemplate a device that weighs less than 250 grams, with an anticipated cost of under $1000 CAD per unit.
The wearable unit meets the required weight threshold, providing a lightweight and practical solution suitable for extended field deployment. We anticipate that the DND opportunity provides for an initial annual order of approximately 5,000 units. In addition, the Company will be submitting the design to foreign militaries later this year.
Micromem now intends to proceed with the next stage of development and construction of the wearable device platform for demonstration purposes.
The Company believes the technology can support a broad range of military, security, and first-responder applications providing real-time sensing and monitoring capabilities in challenging operating environments.
Achieving target cost parameters while maintaining a lightweight design represents an important milestone for the program. Micromem is encouraged by the progress made to date, including the work performed by the engineering staff that it has hired for this project. The Company looks forward to advancing the wearable platform through the next phase of development.
