Burlington, Ontario--(Newsfile Corp. - September 22, 2026) - Promino Nutritional Sciences Inc. (CSE: MUSL) (OTCID: MUSLF) (FSE: 93X) ("Promino" or the "Company") today reported preliminary, unaudited net revenue of approximately C$198,500 for August 2026. With cost of revenues of approximately C$70,200, positive gross profit margins were achieved.

August represented an acceleration in revenues and gross margins as the Company returned to inventory following product constraints during the first half of the year. The new inventory features Promino's proprietary Rejuvenate Muscle Health™ formula, including essential amino acids and 1,000 IU of plant-based Vitamin D3 to support muscle strength and function.

A significant portion of August revenue resulted from the previously announced Kroger 90-day Rejuvenate retail test, which shipped beginning in late July 2026. The program expands Rejuvenate's U.S. shelf presence across multiple Kroger banners, including Ralphs in Southern California, introducing the brand to new consumers through one of North America's largest grocery retailers.

"August is an important indication of what Promino can begin to accomplish with inventory back in place," said Vito Sanzone, Chief Executive Officer of Promino. "The Kroger program expands Rejuvenate's retail presence, with our new proprietary formula reaching consumers and our e-commerce channels rebuilding. After a constrained first half of 2026, we are focused on scaling from here."

Promino is building a broader muscle-health platform across mass retail, pharmacy, e-commerce and sports nutrition channels, centered around convenient, science-based nutritional solutions supporting muscle health, strength and recovery.

The revenue figures contained in this release are preliminary and unaudited, have not been reviewed by the Company's auditor and remain subject to normal period-end review and adjustments, if required. Final reported results may differ from the amounts presented above.
