Vext Secures State Approval for Portsmouth Dispensary Ownership Transfer

• Upon closing, expected by October 1, 2025, Portsmouth will become Vext's fifth fully consolidated dispensary in Ohio. The Company expects to bring additional locations online through late 2025 and early 2026, progressing toward the state's eight-store cap.

Vancouver, British Columbia--(Newsfile Corp. - September 17, 2025) - Vext Science, Inc. (CSE: VEXT) (OTCQX: VEXTF) ("Vext" or the "Company"), a U.S.-based cannabis operator with vertical operations in Arizona and Ohio, today announced that it has received regulatory approval from the Ohio Department of Commerce to transfer ownership of the Herbal Wellness Center dispensary in Portsmouth, Ohio (the "Dispensary") to Vext. The Company expects to complete the closing and associated title transfers by October 1, 2025.

Eric Offenberger, CEO of Vext, commented, "State approval of the Portsmouth dispensary ownership transfer is a clear validation of our disciplined growth strategy in Ohio. With Portsmouth already operating and expected to be consolidated by October 1, we are advancing toward a five-store retail footprint in the state. Each additional location enhances our ability to better leverage our vertically integrated platform, supporting margin expansion and consistent cash flow generation. As we scale, our commitment to compliance, community engagement, and delivering high-quality products remains central to our success. Ohio is proving to be one of the most attractive growth markets in U.S. cannabis, and each milestone brings us closer to completing our retail buildout and enhancing long-term shareholder value."

Located in southern Ohio along the Ohio River, the Portsmouth Dispensary includes a drive-thru, providing added convenience for customers. The Portsmouth Dispensary was granted a provisional license by the Ohio Division of Cannabis Control ("DCC") under the 10(B) license program. Following completion of the Company's Ohio Expansion Transaction, it became part of Vext's retail footprint and as previously announced, officially opened to the public on June 13, 2025.

Construction and permitting is actively underway on the Company's three remaining Ohio locations, with Vext working closely with zoning authorities and regulators to maintain project timelines. Once completed, Vext expects to operate the state maximum of eight dispensaries, supported by its Tier I cultivation and manufacturing facilities. With full vertical integration and a growing retail footprint, Vext is well-positioned to continue to drive margin expansion, generate sustainable free cash flow, and serve both medical and adult-use consumers across Ohio.
