GrowthStalk Holdings Corp., a vertically integrated cannabis investment and operations platform, announced the acquisition of an 40% equity stake in Hash a solventless cannabis producer in Oklahoma, advancing GSTK’s strategy to assemble a scalable, vertically integrated cannabis operating platform.
This transaction represents a strategic inflection point, providing GSTK with direct ownership in a premium processing platform that has demonstrated the ability to outperform in one of the most competitive cannabis markets in the U.S.
Hash RX, known for its technical innovation, operational excellence, and efficiency. Operating in Oklahoma—where wholesale prices have compressed to near operating margins—Hash Rx has consistently delivered strong performance while many competitors have struggled to remain viable.
This resilience is driven by:
- Advanced solventless extraction techniques developed and refined in-house
- A near-zero waste operating model, maximizing value across the entire production lifecycle
- Lean manufacturing and just-in-time production, optimizing throughput and working capital
- Institutional-grade cost accounting and process control, enabling disciplined margin management
Together, these capabilities allow Hash Rx to thrive where others merely survive—making it an ideal platform asset for the Company.
In addition to acquiring a leading operating platform, GSTK gains the benefit of proven leadership and execution capability through Hash Rx’s management team.
Hash Rx’s founder and CEO Joseph Neihart brings deep, hands-on experience across cultivation, extraction, operations, and supply chain management, with a track record of building and scaling cannabis businesses from the ground up in Oklahoma’s highly competitive market.
