Arizona Tribune - BioLargo Relaunching CupriDyne(R)-Based Consumer Products - Back by Popular Demand and Generated More than $125 Million in Pet-Care Sales

WESTMINSTER, CA / ACCESS Newswire / July 13, 2026 / BioLargo, Inc. (OTCQX:BLGO) today announced that it is preparing to relaunch CupriDyne^®-based consumer pet products under a yet-to-be-announced brand. Targeting pets first, the new consumer products subsidiary will eventually expand into household odor and cleaning products. Formed to fill the gap left by Pooph's ongoing withdrawal from the market, BioLargo will sell direct to consumers and through online marketplaces such as Amazon, leveraging a "digital-first" strategy that allows for hyper-specific audience targeting, real-time performance tracking, and flexible budgets, rather than depending on expensive television campaigns.

CupriDyne-based pet products generated over $125 million in sales while under license and marketed under the Pooph brand. Unfortunately, a series of business decisions by Pooph's management later culminated in its abandonment of CupriDyne-formulated products, the foreclosure of their assets by their lender, board and CEO resignations, and what appears to be the cessation of business operations. BioLargo always owned the CupriDyne technology and had to revoke Pooph's license. Now, the ownership of the Pooph brand is embroiled in litigation. "As a result, we have an opportunity to leverage the prior marketing success by introducing our own brand" said Joseph Provenzano, who will lead the new BioLargo consumer products subsidiary as CEO.

BioLargo's launch brings the CupriDyne^® technology and BioLargo's original products back to consumers who loved them. According to Grand View Research¹, the U.S. pet odor control and clean-up products market was valued at approximately $6.47 billion in 2023 and is projected to reach approximately $8.87 billion by 2030. BioLargo's initial launch into pet odor control is part of a much larger home and pet cleaning opportunity. The company views pet care as a proven, well-defined category where the difference between masking and eliminating odors is immediately obvious to consumers. Unlike the Pooph brand, BioLargo's new brand will not be limited to pets, and will use the pet product launch to anchor a broader expansion of CupriDyne products across the home.

BioLargo has assembled a team of branding, marketing, creative, and channel-sales experts with proven track records building and growing consumer brands nationally in the pet and household categories. It plans to release additional information, including the product line, the brand name, and key team members, as the product nears its formal launch.

"It will be great to get back into the pet odor control and consumer products business", said Dennis Calvert, BioLargo CEO. "We have seen what can be done, and this time we will own the brand and control the marketing and distribution."
