Vancouver, British Columbia--(Newsfile Corp. - December 17, 2025) - Plurilock Security Inc. (TSXV: PLUR) (OTCQB: PLCKF) ("Plurilock" or the "Company"), a global cybersecurity systems integrator, announces a two-year licensing agreement valued at $2,449,255 million with a Nasdaq-listed semiconductor manufacturer (the "Customer").

The Customer has been a Plurilock client since 2024, and the Company has previously delivered multiple cybersecurity solutions and services to support the Customer's evolving security requirements across its global operations.

Under the agreement, Plurilock will provide the Customer with an advanced insider-risk software solution through one of its strategic technology partners.

"Large enterprises continue to prioritize security solutions that can be deployed efficiently while aligning with their operational and risk-management objectives," said Ian L. Paterson, CEO of Plurilock. "This agreement demonstrates the strength of our partner-led delivery model and our ability to support sophisticated customers with solutions that scale alongside their business."

Consistent with Plurilock's historical software licensing arrangements, the Company expects fulfillment and delivery to align with previously disclosed operating practices, as outlined in its most recent MD&A. Additional details regarding the commercial terms of the agreement remain confidential.
