BioLargo

What BioLargo does

BioLargo, Inc. is a publicly traded cleantech and life sciences company (OTCQX: BLGO) headquartered in Westminster, California, organized into five wholly-owned operating subsidiaries across three U.S. states and one Canadian province: BioLargo Equipment Solutions & Technologies (PFAS water treatment via the Aqueous Electrostatic Concentrator, or AEC), Clyra Medical Technologies (FDA 510(k)-cleared ViaCLYR wound irrigation using Clyrasept copper-iodine antimicrobial technology), BioLargo Energy (Cellinity molten salt battery for grid-scale long-duration energy storage), BioLargo Engineering, Science & Technologies (BLEST, environmental engineering and consulting), and ONM Environmental (CupriDyne odor and VOC control).

The company's technology portfolio is anchored by 20+ patents held by CSO Kenneth Code, including the AEC electrostatic PFAS concentration system (which achieves >90% energy reduction and avoids secondary waste streams compared to activated carbon or ion exchange), the Cellinity liquid sodium battery (positioned as a rare-earth-free alternative to lithium-ion for AI infrastructure and grid-scale storage), the Clyrasept copper-iodine complex powering ViaCLYR, and the CupriDyne odor control platform (historically licensed to Pooph Inc. before the agreement was revoked in 2025 for non-payment of $3.85 million).

BioLargo monetizes through a hybrid model spanning direct equipment sales (AEC municipal deployments), channel-exclusive distribution (Advanced Solution LLC for ViaCLYR in the U.S., Al-Hikma FZCO for MENA), technology integration partnerships (Aquatech MOU for global AEC deployment), engineering service contracts (BLEST), licensing (CupriDyne, historically), and emerging third-party-validated licensing opportunities (Cellinity). The company reported 2025 revenue of $7.8 million (down 56% year-over-year following the Pooph termination), a $15.2 million net loss, and a $3.9 million cash position, while securing its first commercial AEC installation (Lake Stockholm, NJ), its first ViaCLYR stocking order, and two material international distribution and technology partnerships in early 2026.

Revenue model

1. Engineering Services Revenue: BioLargo Engineering, Science & Technologies (BLEST) provides full-service environmental engineering and consulting including compliance, permitting, process design, and more. Revenue from third-party engineering services grew 98% year-over-year, reaching $2 million for 2025. The subsidiary was awarded a $1.2M contract to design a pilot-scale minerals processing facility in April 2026.
2. Licensing and Royalty Revenue: BioLargo monetizes its proprietary technologies through licensing agreements. The CupriDyne technology was licensed to Pooph Inc., which built a nationally recognized consumer brand reaching over $50M in annual sales before the license was revoked in 2025 for non-payment ($3.85M owed). The company continues to pursue licensing and channel partnerships for its technologies.
3. Product Sales (Medical Devices): Clyra Medical Technologies commercializes wound care products (ViaCLYR) through distribution agreements. The company secured its first commercial stocking order from Advanced Solution in February 2026, marking the transition to revenue-generating operations. International distribution is handled through Al-Hikma FZCO for Middle East and North Africa markets.
4. Product and Equipment Sales (Water Treatment): BioLargo Equipment sells and deploys PFAS treatment systems (AEC) directly to municipal and industrial clients. The first commercial deployment was the Lake Stockholm municipal water facility installation in New Jersey. Revenue model includes direct sales combined with channel partnerships (Aquatech MOU) for broader market reach.
5. Government and Research Grants: BioLargo has secured over 90 awarded research grants across its history. Dr. Richard Smith at BioLargo Water has secured over 60 research grants. Grants support R&D for water treatment, PFAS remediation, and other environmental technologies. The company leverages academic, municipal, and commercial collaborations.
6. Battery Technology (Emerging): BioLargo Energy's Cellinity battery technology is in development and evaluation phase. U.S. BESS Corporation conducted an independent evaluation confirming breakthrough performance for grid-scale energy storage. The company positions this as targeting the large AI infrastructure investment cycle. Not yet generating material revenue.

Direct peers

• Aquatech: Global water treatment company specializing in PFAS and industrial water solutions. While also a current BioLargo partner (May 2026 MOU), Aquatech offers integrated PFAS destruction flowsheets that include concentration/collection steps, making it both a collaborator and a competitive benchmark for AEC technology.
• Form Energy: Long-duration energy storage company developing iron-air battery technology for grid-scale applications (100+ hour discharge). The most direct competitor to BioLargo's Cellinity molten salt battery in targeting AI infrastructure, renewable integration, and utility-scale LDES customers.
• ESS Inc. Public long-duration energy storage company using iron flow battery technology for commercial and utility-scale applications. Direct comparable to Cellinity in the long-duration storage category, particularly for renewable energy and microgrid customers.

Emerging players

• Cyclopure: Emerging PFAS removal technology company using novel adsorbent materials for water treatment. Directly comparable to BioLargo's AEC as a next-generation PFAS remediation approach targeting municipal and industrial water customers seeking alternatives to activated carbon.
• Regenesis: Environmental remediation technology company offering in-situ and ex-situ treatment solutions including for PFAS-impacted sites. Comparable to BioLargo's BLEST engineering and PFAS remediation capabilities for industrial and government environmental projects.

Broad incumbents
