Argo Graphene Solutions reports cement performance results with STREAM graphene

Vancouver, British Columbia--(Newsfile Corp. - July 13, 2026) - Argo Graphene Solutions Corp. (CSE: ARGO) (OTCQB: ARLSF) (FSE: 94Y) ("Argo" or the "Company") is pleased to announce encouraging initial performance results from its graphene oxide cement additive program utilizing graphene produced through the proprietary STREAM™ graphene production platform licensed exclusively from Grapherry, Inc. The Company also announces that it has become a member of the Advanced Carbons Council, further strengthening Argo's participation within the global advanced carbon materials industry. These developments represent important milestones as Argo continues executing its strategy of commercializing proprietary graphene technologies across multiple high-growth industrial markets. Initial Commercial Validation of STREAM™ Technology The graphene oxide ("GO") used in the testing was manufactured utilizing Grapherry's proprietary STREAM-G™ and STREAM-O™ production processes, directly linking the performance results to the proprietary technology platform that now forms the foundation of Argo's long-term graphene commercialization strategy under its previously announced exclusive worldwide licence agreement.

Initial testing demonstrated that the addition of only 0.05 wt.% graphene oxide, equivalent to approximately five parts graphene oxide per 10,000 parts cement by weight, increased ultimate compressive strength by approximately 60% compared to control samples. Testing was performed using ASTM-standard 2-inch by 2-inch cement specimens cured for seven days prior to compression testing. Importantly, the results were reproduced consistently across multiple independent test batches, providing encouraging early validation of the technology's performance.

Graphene oxide functions as a nano-additive within cementitious materials by improving cement hydration, refining pore structure, reducing microcracking, and enhancing load transfer throughout the cement matrix. These improvements can be achieved using extremely low additive concentrations, making graphene oxide an attractive candidate for commercial-scale construction applications. Management believes these initial results represent an important milestone in demonstrating that graphene produced using the proprietary STREAM™ platform can deliver meaningful and reproducible performance improvements under commercially relevant testing conditions.

While seven-day compressive strength testing provides valuable early performance data, the Company notes that 28-day compressive strength testing is the industry benchmark for structural concrete applications. Argo intends to continue its testing program and believes future 28-day results will provide additional validation as commercialization efforts continue. Dr. Vikas Berry, Director of Argo Graphene Solutions and Founder of Grapherry, states, "One of the primary objectives in developing the STREAM™ technology platform was to produce graphene capable of delivering measurable performance improvements in commercially relevant applications.

These initial results are particularly encouraging because they demonstrate a significant, reproducible increase in compressive strength using an extremely low graphene oxide dosage. While the industry typically references 28-day compressive strength results for structural concrete applications, these seven-day results provide an important early validation of the technology and establish a strong foundation for the next phase of testing and commercialization." Commercial Opportunity Construction materials represent one of the world's largest industrial markets. The global cement market alone is estimated to exceed US$350 billion annually, while the broader concrete and construction materials sectors represent substantially larger market opportunities.

A consistent increase in compressive strength at extremely low graphene oxide loadings could provide manufacturers with greater flexibility to develop stronger concrete products or potentially reduce cement usage while maintaining required structural performance. Such advancements may provide both economic benefits and support industry efforts to reduce environmental impacts, particularly as cement production is estimated to account for approximately 8% of global carbon dioxide emissions. Management believes graphene-enhanced cement represents one of several significant commercialization opportunities being pursued by the Company, alongside energy storage, semiconductors, advanced electronics, artificial intelligence infrastructure, agriculture, coatings, composites, and advanced industrial materials.

Joining the Advanced Carbons Council Argo is also pleased to announce that it has joined the Advanced Carbons Council (ACC), an international industry association dedicated to advancing the commercialization of advanced carbon materials, including graphene, carbon nanotubes, carbon fibers, and related technologies. The Council promotes collaboration among industry participants, supports technical and regulatory initiatives, encourages commercialization of advanced carbon materials, and provides members with opportunities to participate in industry working groups, technical discussions, and market development initiatives. Management believes membership in the Advanced Carbons Council will enhance Argo's visibility within the rapidly evolving graphene industry while supporting the Company's long-term commercialization strategy through increased collaboration with technology developers, manufacturers, researchers, and potential commercial partners.

Sean McAlpine, Interim Chief Executive Officer of Argo Graphene Solutions, commented, "These encouraging initial results represent the first commercial validation of the proprietary STREAM™ technology since its integration into Argo. While additional testing remains underway, including industry-standard 28-day cure testing, we believe these results demonstrate the potential of our graphene platform to address meaningful opportunities within the global construction materials industry. Combined with our membership in the Advanced Carbons Council and our broader commercialization strategy across multiple industrial sectors, we continue to execute on our vision of building a vertically integrated graphene commercialization company."
