DESCRIPTION OF BUSINESS

Our Business - Innovator and Solution Provider

BioLargo is in the business of creating new cleantech technologies to solve tough, globally relevant problems. We invent, develop, then commercialize technologies that tackle difficult challenges in air quality, water, environmental engineering, battery energy storage, and advanced antimicrobial medical device platforms. Our model is to invent new technologies that solve specific problems, develop them and prove they work, and then commercialize them with purpose-suited subsidiaries, identify and secure the right partnerships to increase their commercial reach, or potentially sell the intellectual property.

Why do we do this work? Every member of our team - including PhD scientists, engineers, and entrepreneurs - has a passion for seeking new, never-before-seen innovations that can make life better around the world. We care about safeguarding the environment and human health for future generations. We care about making technologies that are affordable and flexible enough to be accessed around the world. And we care about being the best at what we do - creating best-in-class technologies to solve meaningful cleantech challenges.

Some of our areas of focus include environmental problems like PFAS contamination, water pollution by pharmaceuticals and micropollutants, air pollution by VOCs, hard-to-treat odors from landfills and sewage plants, infection and wound healing and the creation of energy storage systems that are more affordable, efficient, safer and environmentally friendly.

Below you'll read about the cleantech ventures and projects we are focused on commercialization today. Behind those, however, is a pipeline of other cleantech innovations in various stages of development associated with our expansive array of issued and pending patents, and that have been funded in part by over 90 government grants.

We operate our business in distinct business segments:

●

Odor and VOC control products, including consumer pet and household products and CupriDyne Clean Industrial Odor Eliminator, sold by our subsidiary ONM Environmental, Inc.;

●

Water treatment equipment and solutions, including our PFAS remediation system the Aqueous Electrostatic Concentrator (AEC), our water reuse and recycling technology co-developed with Garratt-Callahan called AROS, and sold by our subsidiary BioLargo Equipment Solutions & Technologies, Inc.;

●

Battery energy storage systems designed for grid-scale energy storage and other industrial uses under the brand name CellinityTM being developed by our partially owned (93%) subsidiary BioLargo Energy Technologies, Inc.;

●

Medical products based on our technologies sold by our partially owned (48%) subsidiary Clyra Medical Technologies, Inc.;

●

Our professional engineering services division, which, in addition to serving outside clients on a fee for service basis, supports our internal business units, through our partially owned (70%) subsidiary BioLargo Engineering, Science & Technologies, LLC ("BLEST");

●

Our research and support personnel, through our wholly-owned subsidiary BioLargo Canada, Inc., located on campus at the University of Alberta, Edmonton, Canada.

Odor Control (Consumer and Industrial)

ONM Environmental, Inc. ("ONM") is BioLargo's wholly-owned subsidiary that delivers robust and comprehensive products and services to control and mitigate odor and VOCs for both consumer and industrial applications. Its flagship product - CupriDyne® Clean - is applied to odor-emitting masses such as landfills and composting facilities by misting systems, sprayers, water trucks and similar water delivery systems designed, manufactured and installed by ONM. It is also sold to third parties under private label brands.

Consumer Private-Label Products

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 Part II, Item 1, Legal Proceedings below.)

We are focused on redeploying its technology with new partners that share our commitment to quality, transparency, and integrity, and expand the reach of our proven odor-control technology into new markets, providing consumers with safe, effective, and environmentally friendly products. We do not expect the Pooph litigation to affect our other business units or growth strategy. The success of the pet-odor consumer products is an example of our goal to develop distribution channels that do not rely on our in-house sales and distribution infrastructure. While Pooph is by far the company's most successful private label product thus far, we sell other private label odor-control products and continue to pursue related business opportunities as a means of tapping into new markets.

Industrial Odor and VOC Solutions

We believe CupriDyne® Clean is the number-one performing industrial odor-control product in the market, and that it offers substantial savings to our customers compared with competing products. We have been and expect to continue selling product to municipalities and some of the largest solid waste handling companies in the country to help control odors emitted from waste handling and sanitation sites. ONM Environmental offers a menu of services to landfills, transfer stations, wastewater treatment facilities as well as facilities in non-waste related industries. These services include engineering design, construction, installation, ongoing maintenance and on-site support services to assist our clients in the implementation and continued use of the various systems that deliver our liquid products in the field (such as misting systems). A significant portion of industrial odor control product and service revenue comes from ongoing contracts with cities and counties in Southern California, where ONM has installed comprehensive odor control systems to mitigate nuisance odors emitted from municipal waste handling and sanitation sites.

BioLargo Equipment Solutions & Technologies -Innovative Water Treatment Solutions

Over the years, we have developed multiple innovative technologies and equipment platforms that focus on challenging issues in the water treatment industry, including the AEC (developed to remove per- and polyfluoroalkyl substances, aka "PFAS"), and the AROS water reuse technology (for industrial cooling tower water recycling such as in data centers, co-developed with Garratt-Callahan). We sell these products through our wholly-owned subsidiary BioLargo Equipment Solutions & Technologies, Inc. ("BEST"), which manages the sales and distribution of our water treatment products and related services.

BLEST's board of directors includes Jeffrey Kightlinger, former CEO of the Metropolitan Water District of Southern California, Sally Gutierrez, retired career senior executive from the US Environmental Protection Agency (EPA), and Larry Dick, former Vice Chairman of the Metropolitan Water District of Southern California and board member of the Municipal Water District of Orange County. Each brings their significant and distinctive experience from decades in the water industry to BEST's board to help the company create the necessary regulatory and industry connections that will be critical for its efforts to secure larger and more high-profile projects for its PFAS treatment and other water treatment technologies. These board members have been instrumental in efforts to raise awareness of our innovative treatment solutions within the water industry and EPA.

Securing sales in the water and wastewater industry is a very technically intensive process and can be long and arduous. The entirety of the sales cycle can be lengthy, in some cases even taking many months or, in the case of very large projects, multiple years. A typical sales timeline for a municipal drinking water or wastewater customer, from introduction to signing the contract for a full-scale install, usually requires feasibility studies, on-site pilot projects, budget approvals, State regulatory approvals, and more. Industrial clients may have a shorter sales cycles but are under pressure to ensure that the Return on Investment (ROI) fits into company standards, so their reviews can also be lengthy. For any water treatment project, the process is also very engineering-intensive, and therefore the staff required to secure contracts for water treatment projects need to be engineers, in most cases. In our company, BLEST's engineers fill this role.

AEC, a solution for the PFAS "forever-chemicals"crisis

One of the most significant and timely innovations in our portfolio is our per- and polyfluoroalkyl substance (PFAS) water remediation system the Aqueous Electrostatic Concentrator (AEC), a novel water treatment system that removes PFAS from water at a lower operating cost while generating only a fraction of the PFAS-laden waste of the most common currently used solutions (carbon filtration, ion exchange, and reverse osmosis). PFAS are a group of man-made chemicals used for decades in the manufacture of both household and industrial goods, which have been detected in drinking water around the world. PFAS are a concern because they do not break down in the environment, can move through soil and contaminate drinking water sources, and build up (bioaccumulate) in fish, wildlife and humans. PFAS chemicals have been linked to cancer, immune disorders, liver dysfunction, and many other human health problems. Detection of unsafe levels of PFAS around the world has given rise to a number of market opportunities for treatment and remediation technologies, including in drinking water, industrial wastewater, municipal wastewater, solid waste, organic foods and more.

We have successfully validated the AEC as an effective system to selectively extract and collect PFAS chemicals from contaminated water, including performance testing that shows "non-detect" levels of removal, which meets new EPA standards. We have demonstrated more than 10,000 hours of continuous operation showing no materially significant degradation of the AEC system's components or performance over time, and believe the costs to operate our system will be far less than that of the two primary incumbent technologies.

As a modular system, we believe the AEC is scalable to small commercial units used in smaller remediation projects for groundwater, wastewater, or landfill leachate, as well as large commercial installations of drinking water treatment facilities, and we believe that our engineering team has the experience to deliver systems to meet the needs of any sized commercial installation. In order to provide a full turn-key solution for our customers, we have developed an expanded offering whereby we can bundle a service package with each customer project that includes a membrane exchange program, the collection of PFAS, and transport and destruction of the PFAS using a novel "electrooxidation" process which our studies have shown is capable of reaching non-detect levels of PFAS after treating AEC-concentrated PFAS containing water, wastewater, or even landfill leachate (the contaminant-laden water that drains from landfills).

Our AEC unit has been installed and is up and running in Lake Stockholm, New Jersey, removing PFAS from drinking water for local residents. The AEC's performance is undergoing regular testing by both the U.S. EPA and the New Jersey Department of Environmental Protection. This project may 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 position within the PFAS treatment market. We remain committed to delivering scalable, cost-effective solutions that align with evolving regulatory requirements and market demand.

We believe we are well-positioned in the PFAS-removal market for multiple reasons. We have successfully completed over a dozen pilot studies with prospective customers' PFAS contaminated water from a variety of source waters including groundwater, wastewater and leachate; we have successfully maintained operation of our AEC PFAS treatment system for over 10,000 hours continuously, thus demonstrating its resilience to long-term use; we have submitted bids and proposals and have received indications of interest from a wide range of customer types; we have added several high-profile experts from the industry to our team who are assisting in opening doors to potential clients and collaborators; we have entered into discussions about partnership and opportunities for collaboration with industry-leading firms who have a gap in their PFAS treatment technology portfolio. While these opportunities do not convert into commercial sales overnight, but they represent strong avenues for accelerating adoption of our PFAS treatment solution.

AROS Minimal Liquid Discharge Water Treatment

In partnership with Garratt-Callahan, one of the country's oldest and largest privately held water treatment companies, our engineers developed a "minimal liquid discharge" wastewater treatment system called the Aqueous Reuse Optimization System (AROS) that is designed to minimize industrial wastewater discharges and thus the associated regulatory fees. The system is particularly well-suited for cooling towers at data centers and other high-water-use facilities. Garratt-Callahan, who invented and patented the technology, is actively marketing the AROS system to its existing customer base and to new prospective customers. BLEST will serve as the manufacturing partner and Garratt-Callahan will serve as the selling distributor to leverage their national sales force and over one hundred years of providing services and products to customers.

Advanced Oxidation System (AOS)

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.

BioLargo Energy Technologies, Inc.

Our subsidiary BioLargo Energy Technologies, Inc. ("BETI") was founded to commercialize a novel battery technology with the potential to help facilitate the ongoing shift toward renewable energy production by providing a safer, longer lasting, more eco-friendly, and more affordable alternative to lithium-ion batteries. Designed for long duration energy storage, also known as "battery energy storage solutions" (BESS), our battery, called Cellinity™, uses a novel "liquid sodium" chemistry that uses common domestically sourced materials, and which has significant advantages over other battery chemistries for use in stationary, long-duration energy storage.

BETI operates out of a pilot-scale battery production facility in our Oak Ridge Tennessee engineering headquarters, and is currently manufacturing and testing prototype battery cells. A third party has confirmed many of the technology's exceptional performance claims that we believe will make it an attractive battery technology for long duration energy storage and other industrial uses such as artificial intelligence data centers, electric vehicle charging stations, and renewal energy, including the stability of the chemistry of the battery cell and the reliability of the component construction as a sealed, non-venting cell design with no self-discharging, and the battery's ability to quickly charge and discharge at a high voltage. It has also been proven that the battery can withstand catastrophic physical insults without causing fire or explosion, one of the battery's key features. With this data confirmed by a third party, our engineers have begun work advancing Cellinity's development, including the design of a larger sized battery cell that would then be incorporated into battery packs, modules and batteries meant for industrial facilities. Simultaneously, our engineers are working to develop manufacturing processes that would allow scale production and a supply chain necessary to ensure costs of goods in line with market demand and conditions.

	●	Increased safety, no runaway fire risks, and a more sustainable design - with no rare-earth elements - that is capable of being manufactured completely from a domestic supply chain;
	●	Ability to charge and discharge completely, with no degradation of performance, ensuring virtually unlimited charge/discharge cycles, and without self-discharge and no out-gassing; and
	●	Increased energy efficiency and energy density, and expected useful life expectancy of up to 20 years or more.

We are exploring multiple opportunities to commercialize our Cellinity batteries through joint ventures with third parties. The third parties would finance the construction of independent battery manufacturing facilities designed and built under the direction of our engineers, and the joint venture would market, manufacture and distribute batteries. BioLargo would (i) receive a minority equity position in each joint venture, (ii) separately manufacture and sell at a profit to the joint venture certain proprietary battery components, and (iii) receive a royalty on the revenues of the joint venture.

Given the global growing demand for better batteries, and, while we are witnessing a number of current examples in which battery manufacturers have secured forward-contracts to supply batteries to its customers with backlogs of orders that amount to multiple years of production capacity, we believe our offer to partner with customers to secure needed inventory provides for a clear potential pathway to access capital, and more readily scale up production to meet demand around the world. At this point, we do not intend to finance and build our own manufacturing facilities, nor would we develop in-house sales channels, although that possibility remains an option to explore if needed.

Clyra Medical Technologies, Inc.

Our partially owned subsidiary Clyra Medical Technologies, Inc. is a healthcare company that is developing and commercializing products based on our technologies designed to safely treat wound and skin infections and promote wound healing, while reducing the need for antibiotics. Clyra's first products are based on its patented Clyrasept™ technology, which utilizes a Copper-Iodine Complex Solution (CICS) and received premarket clearance from the FDA under Section 510(k). Its first product is ViaCLYR™, a pH-balanced wound management solution indicated for wound management, cleansing, irrigation, moisturization, and debridement of acute and chronic wounds and burns, sold through wholesale distributors and sales agents. Clyra received a first purchase order for the ViaCLYR™ product from a U.S. based distributor in February 2026, and in May 2026 signed a distribution agreement with Al- Hikma FZCO, a healthcare distribution and marketing group headquartered in Dubai, United Arab Emirates, to exclusively distribute ViaCLYR™ across 18 countries spanning the Gulf Cooperation Council, the Levant, North Africa, and select adjacent markets.

Clyra has 12 full time employees, and has increased staff and raised capital to ready the company to launch additional products. Clyra's management team includes Medical Director Dr. Jeffrey Marcus, who is Chief of Plastic, Maxillofacial, and Oral Surgery at Duke University, Nicholas Valeriani, chairman of the board of directors of Edwards Lifesciences and who had a 34-year career with Johnson and Johnson where he held numerous leadership positions in engineering, manufacturing, sales and marketing, and Linda Park of Edwards Lifesciences, where she serves as Corporate Secretary, Senior Vice President and Associate General Counsel, and as a board member of the Edwards Lifesciences Foundation.

Full Service Environmental Engineering

BioLargo Engineering, Science & Technologies, LLC ("BLEST") offers full service environmental engineering to third parties and provides engineering support services to our internal teams to accelerate the commercialization of our technologies.

BLEST focuses its efforts in three areas:

	●	providing engineering services to third-party clients as well as affiliated BioLargo entities;
	●	supporting internal product development; and
	●	advancing their own technical innovations such as the AEC PFAS treatment technology and the Cellinity battery energy storage system.

BLEST operates out of an engineering facility in Oak Ridge, Tennessee (a suburb of Knoxville), and employs a group of scientists and engineers, many of whom are owners of the entity (BioLargo owns 70% as of March 31, 2026 and December 31, 2025). The team is led by Randall Moore, who served as Manager of Operations for Consulting and Engineering for the Knoxville office of CB&I Environmental & Infrastructure and was formerly a leader at The Shaw Group, Inc., a Fortune 500 global engineering firm. Many of the other team members are also former employees of CB&I and Shaw, with the exception of more recent staff hires. The team is highly experienced across multiple industries and we believe they are considered experts in their respective fields, including: chemical engineering, wastewater treatment (including design, operations, data gathering and data evaluation), process safety, energy efficiency, air pollution, design and control, technology evaluation, technology integration, air quality management and testing, engineering management, permitting, industrial hygiene, applied research and development, air testing, environmental permitting, HAZOP review, chemical processing, thermal design, computational fluid dynamics, mechanical engineering, mechanical design, NEPDES permitting, RCRA/TSCA compliance and permitting, project management, storm water design and permitting, computer assisted design (CAD), bench chemistry, continuous emission monitoring system operator, data handling and evaluation and decommissioning and decontamination of radiological and chemical contaminated facilities. The team has decades of high-level experience in the energy industry. The engineering team has also developed an extended network of trusted engineering subcontractors that assist in serving specific client projects as needed.

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 designated "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. 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 an expanding demand for our growing list of 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, that we will eventually need to secure contract manufacturers to meet the customer demands in the near term as we scale up our infrastructure and work force capabilities.

RESULTS OF OPERATIONS

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

Our wholly-owned subsidiary ONM Environmental generates revenues through sales of our flagship product CupriDyne Clean to industry, including related design, installation, and maintenance services on the systems that deliver CupriDyne Clean at its clients' facilities.

Revenue (ONM Environmental)

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)).

Cost of Goods Sold (ONM Environmental)

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 months ended March 31, 2026, were 35%, a decrease of 19% compared to the same period in 2025. The decrease in cost of goods is due to the change in revenue concentration across product lines.

Selling, General and Administrative Expense (ONM Environmental)

ONM Environmental's selling, general and administrative expenses ("SG&A") totaled $371,000 and increased 24% during the three months ended March 31, 2026, as compared with the same period in 2025. The increase is due to increases in salaries, professional fees and insurance expense.

Operating Income (ONM Environmental)

ONM Environmental generated an operating loss of $95,000 in the three months ended March 31, 2026, compared to operating income of $956,000 for the three months ended March 31, 2025. The operating loss is primarily due to the decrease in revenues.

BLEST (engineering)

Revenue (BLEST)

BLEST generated $538,000 in third-party service revenues in the three months ended March 31, 2026, a 15% increase over the $466,000 in third-party service revenues in the same period in 2025. This increase was due to an increase in fixed fee contracts at U.S. Air Force bases.

In addition to providing services to third party clients, BLEST provides services for internal BioLargo projects. These services are billed internally, are considered intersegment revenue, and are eliminated in the consolidation of our financial statements. In the three months ended March 31, 2026, intersegment revenue for BLEST totaled $259,000 and for the three months ended March 31, 2025, intersegment revenue for BLEST totaled $224,000.

Cost of Revenues (BLEST)

BLEST's cost of revenues includes employee labor, subcontracted costs and material costs. In the three months ended March 31, 2026, costs were 56% of revenues, versus 39% in the same period in 2025. The increase is related to our fixed fee contracts, compared to product sales, which had more direct costs.

Selling, General and Administrative Expense (BLEST)

BLEST's SG&A expenses were $266,000 in the three months ended March 31, 2026, compared to $330,000 in the three months ended March 31, 2025. The decrease is due to the timing of expenses in the prior period and does not reflect a decrease in SG&A activity or employees.

Operating Loss (BLEST)

BLEST generated an operating loss of $380,000 in the three months ended March 31, 2026, compared to an operating loss of $378,000 in the three months ended March 31, 2025. The operating losses are reflective of the focus at BLEST on advancing internal BioLargo projects such as the Cellinity battery and AEC water treatment system.

Clyra Medical

Clyra Medical generated revenues of $154,000 in the three months ended March 31, 2026 and margin of 57%, compared with no revenue in the same period in 2025. The increase in revenue is due to the sale of ViaCLYR® wound irrigation solution to a newly engaged distributor. In the three months ended March 31, 2026, Clyra incurred total costs of $1,712,000, which included $521,000 in research and development expenses. In the same period in 2025, total costs and expenses were $1,315,000, which included $335,000 in research and development expenses. The increases in costs and expenses are primarily related to an increased number of employees, increased product development work, and stock option expense.

BETI

BioLargo Energy Technologies, Inc. (BETI) is developing our Cellinity battery, and has not generated generate revenue. For the three months ended March 31, 2026, it incurred total costs and expenses of $355,000, which included $142,000 in research and development expenses. In the same period in 2025, total costs and expenses were $96,000, which included $60,000 in research and development expenses. We are focused on recruiting business and financial partners to facilitate additional capital investment and move the product to commercialization.

BEST

BioLargo Equipment, Sciences and Technologies, Inc. (BEST) was formed in fiscah year 2024 to commercialize BioLargo's proprietary water treatment equipment, including its PFAS removal device the AEC. As the first AEC sale occurred prior to the Company's formation, and the sales cycle for advanced water treatment systems is long, BEST has not yet generated revenues. We intend future water treatment projects to be contracted through BEST. During the three months ended March 31, 2026, it incurred $90,000 of total expenses. In the same period in 2025, it incurred $58,000 in total expenses primarily related to administrative activities.

Selling, General and Administrative Expense - consolidated

Our SG&A expenses include both cash (for example, salaries to employees) and non-cash expenses (for example, stock option compensation expense). For the three months ended March 31, 2026 consolidated SG&A increased 9% (to $2,755,000) as compared with the three months ended March 31, 2025. The largest components of our SG&A expenses included (in thousands):

		Three Months Ended
		March 31, 2026				March 31, 2025
Salaries and payroll related		$	862			$	1,054
Professional fees			439				202
Consulting			275				402
Office expense			616				403
Rent expense			149				120
Depreciation expense			32				41
Sales and marketing			148				176
Investor relations			112				42
Board of director expense			122				82
Total Selling, General & Administrative		$	2,755			$	2,522

In the three months ended March 31, 2026, our non-cash expenses from the issuance of stock and stock options increased to $699,000 compared to $615,000 for the three months ended March 31, 2025. The majority of this stock option expense is recorded in employee salaries and consulting expense. The reduction in salaries and payroll related expenses is due to an Employee Retention Tax Credit recognized in the first quarter ended March 31, 2026 offset by an increase related to an increased number of employees. Professional fees increased in the three months ended March 31, 2026, due to increased corporate activity related to new private securities offerings for BioLargo and Clyra, legal proceedings related to ONM Environmental, and other organizational needs that required professionals. Office expense increased due to an increase in insurance premiums.

Research and Development

In the three months ended March 31, 2026, we spent $907,000 in the research and development of our technologies and products. This was a increase of 15% as compared to the three months ended March 31, 2025. The increase is primarily due to the timing of project work and available working capital.

Interest Income and Expense

Our interest income for the three months ended March 31, 2026, was $72,000 compared to $28,000 in the three months ended March 31, 2025. Our interest expense for the three months ended March 31, 2026, was $188,000 compared to $93,000 in the three months ended March 31, 2025. The increase is related to the increase of Clyra Medical debt obligations.

Other Income and Expense

For the three months ended March 31, 2026, we did not receive any grant income, compared to $6,000 of grant income for the same period in 2025. Grant income is primarily generated through our wholly owned Canadian subsidiary. The research grants received are considered reimbursement grants related to costs we incur and therefore are included as Other Income. Grant funds paid directly to third parties are not included as income in our condensed consolidated financial statements.

Net Loss

Net loss for the three months ended March 31, 2026, was $3,405,000 a loss of $ (0.01) per share, compared to a net loss for the three months ended March 31, 2025, of $1,921,000 a loss of $ (0.00) per share. Our net loss for the three months ended March 31, 2026, increased because of the decrease in revenue.

The net income (loss) per business segment is as follows (in thousands):

Liquidity and Capital Resources

For the three months ended March 31, 2026, we generated revenues of $1,115,000, had a net loss of $3,405,000, used $2,917,000 net cash in operating activities, and received $3,190,000 net cash from financing activities. As of March 31, 2026, we had current assets of $5,445,000, including $4,122,000 cash and cash equivalents. As of March 31, 2026, we had current liabilities of $4,932,000, and working capital of $513,000. We do not believe gross profits in the year ending December 31, 2026, will be sufficient to fund our current level of operations for the reminder of the year, and therefore expect we will continue to be limited in terms of our capital resources, and therefore expect to continue to need further investment capital to fund our business plans and investments in our new technologies. The foregoing factors raise substantial doubt about our ability to continue as a going concern, unless we are able to increase revenues, generate cash from operations, and/or generate cash from financing activities. 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.

Critical Accounting Policies

Our discussion and analysis of our results of operations and liquidity and capital resources are based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of our condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, valuation of offerings of debt with equity or derivative features which include the valuation of the warrant component, any beneficial conversion feature and potential derivative treatment, and share-based payments. We base our estimates on anticipated results and trends and on various other assumptions that we believe are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results that differ from our estimates could have a significant adverse effect on our operating results and financial position.

Our significant accounting policies and methods used in the preparation of the Company's condensed consolidated financial statements are described in (i) in Part I, Item 1 of this Form 10-Q, Note 2, "Summary of Significant Accounting Policies" and (ii) in the Form 10-K for the year ended December 31, 2025, filed with the SEC on March 31, 2025, in the Notes to Consolidated Financial Statements in Part II, Item 8, and "Critical Accounting Policies and Estimates" in Part II, Item 7. There have been no material changes to the Company's critical accounting policies and estimates since the filing of its Form 10-K.
