(TSXV: ROMJ) (OTCQX: ROMJF) (“Rubicon Organics” or the “Company”), Canada’s leading premium licensed producer focused on cultivating and selling premium and super-premium cannabis products, today announced that its Cascadia indoor cultivation facility in Hope, British Columbia has achieved Good Agricultural and Collection Practices (“GACP”) certification, a globally recognized standard governing the cultivation, harvesting, and post-harvest handling of medicinal cannabis for regulated international medical markets. The Company’s Pacifica facility located in Delta, BC already holds this certification, enabling both facilities to serve both domestic and international markets. “Achieving GACP certification at Cascadia is a testament to the rigorous standards we have embedded across our cultivation operations,” said Margaret Brodie, Chief Executive Officer, “This milestone strengthens our ability to reliably supply international medical markets as we continue to expand our international reach.” GACP certification confirms that Cascadia meets international requirements for product consistency, contamination control, traceability, and documentation, and applies specifically to the agricultural stage of production, supporting the cultivation of high-quality cannabis for regulated medical markets. The 47,500-square-foot Cascadia facility is fully planted and operational, with estimated annual production capacity of up to 4,500 kilograms of premium cannabis. The facility further expands Rubicon’s certified cultivation footprint, supporting demand for 1964 Supply Co.™, Canada’s #1 selling premium cannabis brand in 2025, and underscoring the global appeal of premium cannabis following the brand’s recent successful launch in the UK.
