1. Ownership and Share Structure Information

The information listed above was updated on the date this article was published and was compiled from information from the company and various other data providers.

Alberta's oil sands mines are holding about 1.5 billion cubic meters of fluid tailings, roughly 40% more than a decade ago. For years, the rules have kept that material on site. Now the province wants treatment technologies tested, and some trials are already underway.

BioLargo Inc. (BLGO:OTCQX) performed successful bench-scale trials of its water treatment technologies years ago and now, with those promising early results, is well positioned and is organizing an effort to perform commercial trials of its solutions in northern Alberta, along with a new Indigenous-led venture formed to treat oil sands process water (OSPW). Through its subsidiary BioLargo Canada, BioLargo announced on September 9 that it had formed Tũ Nipi Water Solutions Ltd. in partnership with a Local First Nation member from Fort McKay. The partnership is backed by a conditional grant commitment from Emissions Reduction Alberta in support of a CA$4.6 million project. About CA$2.3 million of that is expected to fund BioLargo's direct work, with the balance supporting other contributors to the project.

Fort McKay Oil Services and Tũ Nipi are private businesses, with no ownership, operational, control, or affiliation ties to Fort McKay First Nation. The First Nation is not a participant in the partnership.

"What we have today is a government pulling technology-based solutions like ours forward, a partner with real standing in the region, and a market that is ready to act," BioLargo President and Chief Executive Officer Dennis Calvert said in the release.

A Billion-Cubic-Meter Problem Meets a Policy Shift

Fluid tailings continue to accumulate at Alberta's oil sands mines. In 2024, the Athabasca region held roughly 1.5 billion cubic meters, compared with about 1.08 billion in 2014, the Alberta Energy Regulator reported in its latest State of Fluid Tailings Management report, published in October 2025. These mixtures of water, sand, clay, and residual bitumen sit in storage at eight mines. Since regulations have long barred the release of oil sands process water, operators have mostly retained it on site.

Policy is beginning to shift. In 2025, Alberta endorsed all nine proposals from its Oil Sands Mine Water Steering Committee, the provincial government said. The recommendations call for industry and researchers to test promising treatment methods, faster development of standards for discharging treated water, and broader monitoring.

Richard Ryan of Oakridge reaffirmed his "Buy" rating in an August 19 report.

"Doing nothing while mine water continues accumulating is not a sustainable long-term approach," then-Environment Minister Rebecca Schulz said when the province adopted the final recommendations in September 2025, Water Canada reported. Mining Association of Canada President Pierre Gratton said the steps offer "the framework and certainty needed by industry to proceed with responsible reclamation of oil sands mines."

Ottawa is acting, too. On June 16, Ottawa introduced Bill C-37, the First Nations Clean Water Act, which would establish enforceable drinking water standards on First Nations lands. The legislation would also enable agreements between First Nations, the federal government, and provinces to safeguard source water in shared watersheds. Ottawa paired the bill with a CA$4.6 billion commitment for water and wastewater infrastructure, Smart Water Magazine reported. That federal funding is separate from the CA$4.6 million Tũ Nipi project.

"Clean water is the top priority of every Canadian Indigenous community, and the regulatory environment is finally catching up to that," Tũ Nipi CEO Ron Quintal said in the release.

Indigenous Leadership, BioLargo Technology

Tũ Nipi brings together Fort McKay Oil Services and BioLargo Canada in a private business venture that is Indigenous-led, with BioLargo Canada as a minority owner. The venture is not owned, operated, controlled by, or affiliated with Fort McKay First Nation. It is based on a Reserve within the community of Fort McKay, Alberta. BioLargo Canada will be primarily responsible for technology development and for running trials for OSPW, wastewater, and industrial uses.

"This is a venture led by First Nations people, in a community that has made embracing future generations its purpose, and we are honored to serve in it," Calvert said in the release. He told Streetwise Reports the venture aims to "help deliver solutions where we can and add value."

What the Grant Funds

The conditional grant commitment supports trials of BioLargo technologies for use in OSPW, the release said. If the grant is finalized, the funding would support large closed-lab testing, the Edmonton Journal reported on September 17.

The work extends beyond OSPW. Tũ Nipi and BioLargo Canada have identified potential clients and an initial wastewater project for which BioLargo's per- and polyfluoroalkyl substances (PFAS) and odor control technologies are in development, the release said.

A Founding Partner in Oil Sands Water Research

BioLargo has worked on oil sands water treatment since 2011, when it became a founding industrial partner in the Natural Sciences and Engineering Research Council of Canada (NSERC) Industrial Research Chair in Oil Sands Tailings Water Treatment at the University of Alberta. The chair was established with funding from government grants, the university, and oil sands producers to find ways to treat OSPW, Calvert said.

That early work ran from 2011 to about 2016, years before the province moved to test treatment technologies. BioLargo Canada is based in Edmonton, in a University of Alberta building, which keeps it in close contact with the university's researchers, Calvert said.

"This is a relationship that was created because we've invested years," Calvert told Streetwise Reports. "It goes all the way back to 2011." In the release, he said, "Our company's roots in this work are Canadian, and this is a return home."

Calvert called the challenge "very dynamic," with environmental, political, and economic dimensions, including First Nations communities' interest in protecting their land and regional interests.

The company brings more to the problem than it did then. "The company has also transformed itself since that time. We now have multiple technologies, commercial deployment, strategic partners, and an experienced team of highly qualified scientists and engineers to support the effort," Calvert said.

Next Up: A Launch and a Grant Decision

Tũ Nipi plans to hold its formal launch event in Fort McMurray in the coming months, with community, government, and industry participants, according to the release. The Emissions Reduction Alberta grant commitment remains conditional.

Calvert views Tũ Nipi as a way to introduce BioLargo's full range of solutions, not simply as a route to a single oil sands contract. "We've got a whole series of tools, and we're really focused on being a solution provider," he said. He pointed to wastewater and drinking water needs, including portable systems for remote First Nations communities.

Calvert said policy decisions and the flow of capital will set the pace, and BioLargo is positioned to respond quickly to both. It brings scientists and 15 years of oil sands water research to a venture that already has a conditional grant commitment from Emissions Reduction Alberta, an Indigenous-led partner based in Fort McKay, and commercial trials being organized in northern Alberta. "We're in a great spot," he said.

A Portfolio That Reaches Well Past Water

BioLargo develops and commercializes solutions for PFAS contamination, water and wastewater treatment, odor and volatile organic compound (VOC) control, and related markets. It also holds a strategic investment and large minority stake in Clyra Medical Technologies Inc., which is ramping up its commercial efforts in wound care and infection control.

It is relaunching its consumer products through BioLargo CPG LLC, using its CupriDyne Clean technology. The company's Cellinity battery technology is also in development for long-duration energy storage.

Analyst Sees Strength in Spreading the Risk

In an August 19 report, Oak Ridge Financial Analyst Richard Ryan described BioLargo's business model as "a hub and spoke format": inventing or acquiring a product, proving it out, partnering with third parties, and commercializing it.

Ryan reaffirmed his "Buy" rating. By commercializing technologies through operating subsidiaries, he wrote, BioLargo "diversifies overall risk, maintains high levels of segment ownership while providing solutions to diversified, high-growth end markets."

Ownership and Share Structure¹

About 13.73% of BioLargo is owned by insiders and management. About 0.04% is held by institutions, based on 13F filings. The rest is retail.

As of October 7, its market cap is US$26.18 million, with about 328.73 million shares outstanding. It trades in a 52-week range of US$0.07 to US$0.20.
