Vancouver, British Columbia  — April 17, 2026 – TheNewswire — Plaid Technologies Inc. (CSE: STIF) (OTC: STIFF) (FRA: 5QX0) (“ Plaid ” or the “ Company ”), a developer of graphene-enhanced technologies, is pleased to announce that it has received technical and market analysis deliverables from its previously announced engagement with Graphene NanoWorks (“ GNW ”).

Under the terms of the agreement entered into on December 16, 2025, the Company engaged GNW for a three-month period at a total cost of $32,500 to conduct market analysis and technical specification development in support of the Company’s graphene-based technology initiatives.

The Company has now completed an initial review of the information generated through this engagement, including technical assessments, performance observations, and market analysis relating to potential applications in sectors such as optical coatings, specialty glass, and advanced materials.

The materials provided by GNW indicate that graphene-enhanced formulations, including formulations incorporating graphene oxide and dispersion methodologies, may warrant further evaluation for their potential to affect certain material characteristics, including durability, surface functionality, and material efficiency. The Company notes that these findings are preliminary in nature and have not been independently verified by the Company.

In parallel with the GNW engagement, the Company has continued development work with its contracted partner, Petro Flow LLC, including the integration of an ultrasonic injection process designed to enhance the dispersion of graphene oxide within cementitious systems. Preliminary observations suggest that improved dispersion may influence hydration behavior and cured material properties.

Based on the technical and market inputs currently available, the Company will begin a structured evaluation of potential commercialization pathways. This process is expected to include:

• Identification and prioritization of target application verticals  

• Assessment of scalable manufacturing and deployment strategies  

• Engagement with potential strategic partners and end-users  

• Evaluation of appropriate corporate structures to support commercialization initiatives  

The Company cautions that while promising, the work completed to date remains preliminary and subject to further testing, validation, and economic analysis.

Guy Bourgeois, Chief Executive Officer of Plaid Technologies, commented:

"The completion of this engagement with Graphene NanoWorks provides us with a stronger technical and commercial foundation from which to evaluate next steps. We are now focused on determining the most effective pathway to translate these findings into scalable, value-generating opportunities."

The Company will provide further updates as it advances its evaluation process and defines its commercialization strategy.

About the Company

The Company focuses on the development and commercialization of graphene-enhanced technologies. Plaid is simultaneously pursuing a range of applications for its proprietary graphene-infused concrete mixture, with an initial focus on wellbore cement and subsurface applications. Management expects Plaid’s unique mixture to pave the way for a new era in well abandonment, combining cutting-edge materials with precision engineering.
