Our strategy to market our PFAS treatment technology and related engineering services is as follows: 1) focus on demonstrating our technology’s efficacy in first demonstration projects, trials, and early customer deployments with the understanding that this early success can be leveraged to secure larger and more numerous subsequent projects, 2) market our PFAS expertise and our technology by presenting at industry events and conferences around the country, cultivating our status as “thought leaders” in the space, 3) use our network of manufacturer’s representatives and channel selling partners to maximize the number of potential opportunities with early adopters, and 4) engage in discussions with credible distribution partners at established water treatment technology companies. Part and parcel to our strategy, we are in the early stages of developing a collaboration with the US EPA to have our AEC technology validated through a rigorous third-party pilot study whereby our technology would be operated and analyzed by EPA staff to a high degree of technical scrutiny. Such third-party validation could significantly facilitate market adoption of the AEC by effectively de-risking the technology for customers.

Credit Loss Expense, Pooph Litigation*
Previous report
On June 6, 2025, ONM Environmental entered into an amendment to the Preferred Master Manufacturing Agreement with Ikigai Holdings, LLC and Pooph Inc. to allow Pooph Inc. to pay past due amounts of $1,378,141 in royalties and $2,385,468 on product invoices through a weekly payment plan bearing 10% interest and maturing July 3, 2026 (the “PMMA Amendment”). This amount was recorded on our balance sheet at June 30, 2025, as a note receivable. The PMMA Amendment also modified payment and invoicing terms on existing and future product purchase orders, and allowed BioLargo to withhold product if the payment terms were not met. On August 5, 2025, Pooph Inc. delivered a royalty report due for the second quarter of 2025, but did not pay the $463,520 in royalties due. On August 15, 2025, it failed to make the weekly payment required pursuant to the PMMA Amendment, and has not made a payment since. On September 19, 2025, Pooph Inc. disclosed that it had been working independently on developing a new formula for Pooph-branded products to replace BioLargo's formula, and that it was terminating the Preferred Master Manufacturing Agreement, citing our refusal to deliver products. On September 24, 2025, BioLargo and ONM delivered notice to Pooph that the grant of license was immediately revoked due to Pooph’s failure to pay royalties, and that it was terminating the License Agreement in its entirety with 150 days’ notice. The notice further advised that Pooph is not allowed to market or sell products that incorporate, use, or are based on, in whole or in part, BioLargo’s patents and proprietary information, including but not limited to know-how, disclosed to Pooph, and that absent reinstatement of the grant of license, Pooph must immediately stop marketing and selling any such products in its possession, custody or control (or sold through market portals or platforms such as Amazon).

On November 11, 2025, we (BioLargo Inc. and ONM Environmental Inc.) filed a lawsuit against Pooph Inc. (and related party Ikigai Marketing Works LLC) in the United States District Court, Central District of California, case number 8:25-cv-02516, alleging patent infringement (35 U.S.C. 271), false advertising (15 U.S.C. 1125), and state law claims including breach of contract, false promise, unfair and fraudulent business practices, and constructive fraud. In the suit, we seek (i) an order that the defendants have infringed on our patents, an injunction enjoining defendants from further infringing on our patents, and accounting for defendants' gains and profits; (ii) an order that defendants have violated Section 43(a) of the Lanham Act, an injunction preventing defendants from using product reviews based on our proprietary technology with their newly formulated products, and an accounting and damages for these violations; (iii) compensatory damages for unpaid royalties of $1,667,292; (iv) compensatory damages for unpaid product purchased from ONM Environmental of $2,154,110, (v) compensatory damages in an amount according to proof for false promises and unfair and fraudulent business practices; (vi) treble and/or exemplary damages; and (vii) costs and attorneys fees. Also on November 11, 2025, Pooph Inc. served ONM Environmental with a lawsuit venued in the Orange County, California Superior Court filed September 11, 2025, case number 30-2025-01511009, alleging ONM Environmental breached the terms of, and the implied covenant of good faith and fair dealing of, the Preferred Master Manufacturing Agreement, seeking damages in an amount to be determined, as well as unjust enrichment, interest, and attorneys fees and costs, arising out of the manufacture and sale of the Pooph-branded products, including the Litterizer cat-litter additive, and ONM Environmental's refusal to full purchase orders while Pooph Inc. was in breach of contract for failure to pay past due monies. ONM Environmental disputes the allegations and intends to vigorously defend the lawsuit. While the outcomes of the lawsuits are uncertain, management believes that the resolutions of these proceedings will not have a material adverse effect on the Company's financial position, results of operations, or cash flows. However, adverse outcomes could materially impact future financial results.
Previous report
During the three months ended September 30, 2025, BioLargo management determined that the note receivable and accounts receivable owed by Pooph Inc. were fully impaired, resulting in a $3,849,000 credit loss expense recorded on our condensed consolidated statement of operations, which reduced operating income and current assets by that amount.

Excluding intersegment revenue, our engineering segment's revenues decreased 34% (to $327,000) in the three months ended September 30, 2025, as compared with the same period in 2024, and decreased 7% (to 1,565,000) in the nine months ended September 30, 2025, as compared with the same period in 2024. The decrease in revenues in the three-month period is due to the timing of recognition of revenue (and related deferred revenue recognition) related to its product sales and its fixed fee contracts at U.S. Air Force bases.
Previous report
BLEST’s SG&A expenses were $198,000 and $752,000 in the three and nine months ended September 30, 2025, compared to $218,000 and $659,000 in the three and nine months ended September 30, 2024. The increase in the nine-month period is due to the hiring of additional employees in 2025.
Previous report
Clyra Medical has not yet begun commercial sales of its products and thus did not generate revenues in the three and nine months ended September 30, 2025 or 2024. In the three and nine months ended September 30, 2025, it incurred total costs and expenses of $1,483,000 and $4,063,000, which included $231,000 and $795,000 in research and development expenses. In the same periods in 2024, total costs and expenses were $857,000 and $2,019,000, which included $291,000 and $512,000 in research and development expenses. The increases in costs and expenses are primarily related to stock option expense recorded as selling, general and administrative expenses and also an increase in product development cost. Although Clyra Medical is working to generate revenue through product sales to multiple distributors, management is not yet in a position to disclose when first sales will commence.

We sell privately labeled odor-control products based on our technologies to third parties who market and sell the products under their own brand names. The most successful thus far has been pet odor control products sold under the brand name "Pooph" by Pooph Inc. In addition to purchasing product from us at an agreed-upon manufacturing margin, Pooph Inc. agreed to pay us a six percent royalty on their sales in exchange for exclusive rights to our technology for pet odors, and agreed that if they sold their brand to a third party, we would receive 20% of the exit value. Pooph defaulted on their payments, we revoked their license to sell pet products with our technology, and sued Pooph for patent infringement and other claims in order to protect our intellectual property. (See subheading "Credit Loss Expense, Pooph Litigation" in Results of Operations, below.)

The AEC’s commercial roll-out is being executed with the help of a network of sales representative organizations whose role will be to market and sell the treatment system, related equipment, and the Company’s engineering services to municipal and industrial customers across the country. We have secured channel partner agreements with several sales representative organizations ensuring coverage for most of the continental United States. The AEC for our PFAS project in New Jersey has been built and is ready for delivery and installation, now waiting on the completion of other supporting infrastructure. We believe the New Jersey project will represent a key milestone for the commercialization of the AEC, as we believe industry validation of the technology in a first municipal drinking water treatment project will play an important role in showcasing the AEC’s distinct advantages over incumbent technologies like carbon filtration and ion exchange. As we progress through the commercial rollout of our AEC technology, we continue to invest in innovation aimed at enhancing its commercial viability. These efforts are focused on improving system performance, reducing lifecycle costs, and strengthening the AEC’s competitive economic position within the PFAS treatment market. We remain committed to delivering scalable, cost-effective solutions that align with evolving regulatory requirements and market demand.

The Advanced Oxidation water treatment system (AOS) is our patented water treatment device that generates highly oxidative and energetic species of iodine and other molecules which allow it to eliminate pathogenic organisms and organic contaminants rapidly and effectively as water passes through the device. The key value proposition of the AOS is its ability to reduce or eliminate a wide variety of waterborne contaminants with high performance, including the normally hard-to-treat class of recalcitrant water contaminants called “micropollutants”, while using very little electricity and input chemicals. The AOS has been proven capable of removing hard-to-treat organic micropollutants such as pharmaceuticals from water more quickly and energy-efficiently than other technologies. While the AOS has demonstrated exceptional performance in both laboratory and pilot-scale testing, current U.S. regulatory frameworks have not yet matured to support broad adoption of advanced oxidation technologies for micropollutant removal. Additionally, the domestic market remains dominated by low-cost chemical disinfection solutions. In light of these market conditions, we have elected to pause daily development activities on the AOS in the near term. However, we continue to monitor evolving regulatory trends in the U.S. and are exploring the possibility of international commercialization opportunities, particularly in Europe where regulatory mandates for micropollutant removal are more advanced. Our business development efforts remain focused on strategic partnerships in the European market and on domestic industrial and pharmaceutical wastewater applications where micropollutants are a significant driver of surcharge fee.

BLEST engineers generate revenue through services to third party clients, as well as for internal BioLargo projects such as the AEC and battery (revenues from internal projects are eliminated in the consolidation of our financial statements and are designed “intersegment revenue”). Third party contracts include ongoing work at U.S. Air Force bases for air quality control which generate ongoing contract-based revenue of approximately $100,000 per month. Efforts to expand this work as well as with other clients are consistently ongoing.

Efforts to expand this work as well as with other clients are consistently ongoing. In April 2026 BLEST was engaged to design a pilot-scale minerals processing facility that will remediate and, utilizing a patented BioLargo process, will create a beneficial reuse of a legacy mineral waste deposit associated with a historically impacted site in the western United States. Work on the $1.2 million contract has begun and is expected conclude by the end of the year, and is expected to lead to the design and construction of a larger processing facility.

The staff time devoted to supporting the AEC (PFAS) and battery related work is demanding, and, BLEST needs to hire more qualified staff to meet and expanding demand for our growing list of customers and/or expected customers. When we combine the demands of current revenue generating projects and expected growth, we are presented with an obvious challenge to manage quality, timely performance as well as access to qualified staff. We are working carefully to find balance to help ensure we meet the demands of both in a practical customer centric and capital conserving way. It may be for example, when we secure larger and larger contracts for PFAS or Garrett Callan related work, we will need to depend heavily on our contact manufactures to meet the customer demands in the near term as we scale up our infrastructure and work force capabilities.

Our revenues decreased 75% and 49% in the three and nine months ended September 30, 2025, as compared with the same periods in 2024, primarily due to a decreased volume of sales of our pet odor control product private labeled to a third party under the brand name “Pooph” (see discussion of related litigation in Part I, Item 2, above). During the three and nine months ended September 30, 2025, revenues from sales to Pooph comprised 35% and 64% of our consolidated revenue; compared to the three and nine months ended September 30, 2024, it comprised 74% and 76% of our consolidated revenue. Our financial statements separate revenue based on products and services. Revenues from the sale of products for the three and nine months ended September 30, 2025, decreased 80% and 58% over the same periods in 2024. Revenues from services for the three and nine months ended September 30, 2025, decreased 21% and 116% over the same periods in 2024.
Current wording
Our revenues decreased 66% in the three months ended March 31, 2026, as compared with the same period in 2025, primarily due to a decreased volume of sales of our pet odor control product private labeled to a third party under the brand name “Pooph”. During the three months ended March 31, 2025, sales to Pooph had comprised 79% of our consolidated revenue; in August 2025 Pooph Inc. stopped purchasing Pooph-branded products from us, and thus revenues from sale of Pooph-branded products during the three months ended March 31, 2026 were zero. We are in litigation with Pooph Inc. and do not expect product sales to Pooph Inc. to resume. Our financial statements separate revenue based on products and services. Revenues from the sale of products for the three months ended March 31, 2026, decreased 79% (from $2,803,000 to $577,000) over the same period in 2025. Revenues from services for the three months ended March 31, 2026, increased 15% (from $466,000 to $538,000) over the same period in 2025.

ONM Environmental’s revenues decreased 80% and 55% (to $776,000 and $5,583,000) in the three and nine months ended September 30, 2025, compared with the same periods in 2024. The decrease in revenues was almost entirely due to a decrease in the volume of sales of our pet odor product private labeled to a third party under the brand name "Pooph". Because the Pooph brand is owned and marketed by a third party, ONM Environmental has no control over its marketing and sales activity. We expect annual revenues for the year ending December 30, 2025, to decrease as compared with 2024.
Current wording
ONM Environmental’s revenues decreased 85% in the three months ended March 31, 2026, compared with the same period in 2025. The decrease in revenues was due to a decrease in the volume of sales of our pet odor product private labeled to a third party under the brand name "Pooph", offset by an increase in sales of industrial odor control products (which increased 90% (from $223,000 to $423,000)).
Previous wording
ONM Environmental’s cost of goods sold includes costs of raw materials, contract manufacturing, and portions of depreciation, salaries and expenses related to the manufacturing and installation of its products. As a percentage of revenue, ONM Environmental’s costs of goods for the three and nine months ended September 30, 2025, were 54% and 51% a decrease of 1% and 3%, compared to the same periods in 2024. The decrease in cost of goods is due to the change in revenue concentration across product lines.

If we are unable to raise additional cash through gross profits or financing activities, management may choose to curtail portions of our operations. The condensed consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.
