A high-visibility location on one of the area’s busiest retail corridors, anchored by neighboring Jungle Jim’s International Market – expected to drive durable store-level performance.

Vancouver, British Columbia–June 1, 2026 – Vext Science, Inc. (CSE: VEXT) (OTCQX: VEXTF) (“Vext” or the “Company”), a U.S.-based cannabis operator with operations in Arizona and Ohio, today announced that its Herbal Wellness Center dispensary in Fairfield, Ohio (the “Dispensary”) has commenced operations and is now open to the public for both medical and adult-use sales. All currency references used in this news release are in U.S. currency unless otherwise noted.

The Dispensary is Vext’s sixth operating dispensary in Ohio. The approximately 3,825-square-foot store is located in Fairfield, a northern suburb of Cincinnati, just off Route 4, a high-traffic commercial corridor. It sits adjacent to Jungle Jim’s International Market, a major regional retail attraction, within a broader retail node that includes national retailers and a large fitness center, a setting that supports strong and consistent consumer traffic. The Company expects Fairfield to become a meaningful contributor to revenue and cash flow as it stabilizes.

Eric Offenberger, CEO of Vext commented, “Opening Fairfield is an important milestone in our disciplined retail build-out. We’ve secured a strong, high-visibility position there, next to one of the region’s biggest retail draws. Our strategy in Ohio is straightforward and a continuation of our long-held playbook – open the right stores in the right locations, supply them from our own highly efficient cultivation operation, and convert that into cash. Every store we add makes the proven model stronger and brings us one step closer to the state’s eight-store cap.”

Vext’s six Ohio dispensaries are supported by its Tier One cultivation and manufacturing facilities in Jackson, Ohio. A seventh dispensary, in Columbus, holds a dual-use provisional license, is under construction and is expected to open in the fourth quarter of 2026. A third dual-use dispensary under the Ohio Division of Cannabis Control 10(B) program remains under evaluation, which would complete the Company’s build-out to the state’s eight-store cap.
