Greenway Reports Expanded International Cannabis Sales

International sales now represent approximately 50% of company sales

KINGSVILLE, ON, May 28, 2026 /PRNewswire/ - Greenway Greenhouse Cannabis Corporation (CSE: GWAY) (OTCQB: GWAYF) ("Greenway" or the "Company"), a cultivator of high-quality greenhouse cannabis for the Canadian market, is pleased to announce the continued expansion of its global cannabis sales program, with approximately half of the Company's current sales now being generated through international channels.

Since commencing international shipments in late 2024, Greenway has continued to methodically increase its exposure to the worldwide medical cannabis markets through established strategic partnerships and disciplined commercial execution.

The Company's global growth strategy has focused on supplying high-quality greenhouse-grown cannabis to markets that value consistency, product quality, and reliable supply relationships. Greenway believes international medical cannabis markets continue to present opportunities for stronger realized pricing per gram compared to the domestic market, supporting improved revenue potential while maintaining the Company's focus on operational efficiency and low-cost greenhouse production. The Company believes this approach positions Greenway to further diversify revenue streams and enhance long-term commercial sustainability.

"International sales have become an increasingly important component of our business," said Jamie D'Alimonte, Chief Executive Officer of Greenway. "Over the past year, we have worked closely with strong strategic partners to steadily grow our presence across the global medical cannabis market, expanding both into new jurisdictions and new product offerings. We believe this measured and disciplined approach supports long-term sustainable growth while allowing us to continue leveraging the efficiency advantages of our greenhouse cultivation platform."

Greenway's current cultivar portfolio has been selected to serve both domestic and international markets. As its export program continues to expand, the Company has also advanced several new cannabis cultivars that may be dedicated primarily to international medical cannabis opportunities. These cultivars are being assessed for attributes the Company believes are important to buyers everywhere, including flower quality, consistent cannabinoid profiles, terpene expression, and repeatable THC results.

Greenway expects these genetics initiatives to support the continued evolution of its global product offering while strengthening long-term relationships with overseas customers and commercial partners.

"Our cultivation team is focusing on providing us with flower that aligns with the evolving preferences of both the domestic and international markets," added D'Alimonte. "As our export business grows, we believe tailoring cultivars specifically for international opportunities represents an important next step in the evolution of our platform and reach."

Greenway's cultivation model combines large-scale greenhouse production with a focus on premium flower quality, allowing the Company to compete in both domestic and international markets while maintaining a strong emphasis on cost control and operational consistency.

As global demand for medical cannabis products continues to evolve, Greenway intends to continue evaluating opportunities to expand international distribution relationships and increase participation in key overseas markets.
