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 products, such as the Pooph-branded pet-odor control product, and our industrial odor control product, 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 our pharmaceutical removal and energy-efficient disinfection solution, the AOS, all sold by our subsidiary BioLargo Equipment Solutions & Technologies, Inc.;
• Battery energy storage system solutions under the brand name CellinityTM being developed by our partially owned (96% subsidiary BioLargo Energy Technologies, Inc.;
• Medical products based on our technologies sold by our partially owned (52%) 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 (74%) 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, including for consumer brands such as the "Pooph pet odor eliminator".

Pooph - 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 is the Pooph branded pet odor control product sold through national retailers including Walmart, Amazon, PetSmart, PetCo, and Chewy.com by Pooph Inc. In addition to purchasing product from us at an agreed-upon manufacturing margin, Pooph Inc. pays us six percent royalty on their sales in exchange for exclusive rights to our technology for pet odors. If Pooph sells their brand to a third party, we would receive 20% of the exit value. During the year ended December 31, 2024, revenues from sales to Pooph comprised 77% of our company-wide revenue; during the three months ended March 31, 2025, it comprised 79% of our revenue. The success of Pooph 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, we sell other private label odor-control products and continue to pursue related business opportunities as a means of tapping into new odor control 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 AOS technology (developed to remove micro-pollutants), the AEC (developed to remove per- and polyfluoroalkyl substances, or 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 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.

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 facilities. 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.

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; 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 minimizes industrial wastewater discharges and thus the regulatory fees associated with wastewater discharge, including for uses like cooling towers at data centers. Garratt-Callahan, who invented and patented the technology, is currently 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. Presently, both BioLargo and Garratt-Callahan are engaged in pilot projects with potential customers for the AROS system, and the companies are currently engaged in discussions with multiple potential first customers for the technology.

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.

Our proof-of-concept studies and on-site pilot projects have generated results that project the AOS will be more cost- and energy-efficient than commonly used advanced water treatment technologies such as UV, electro-chlorination, and ozonation. Furthermore, our technology has been proven capable of removing hard-to-treat organic micropollutants such as pharmaceuticals from water more quickly and energy-efficiently than other technologies. Together, these characteristics make the AOS an economical and versatile tool to enable wastewater treatment and reuse in the face of emerging water contaminants and increasing regulatory scrutiny on industrial wastewater discharge.

The AOS has, broadly speaking, two target applications: 1) treatment of municipal or industrial wastewater to eliminate bacteria, viruses, other organisms, and regulated organic contaminants, while using less electrical energy than other technologies, and 2) treatment of water or wastewater specifically to eliminate micropollutants/pharmaceuticals, at which the AOS particularly excels at compared to existing technologies. Our work to have the AOS adopted in the US and Canada for the first application has been met with resistance because existing technologies, while less energy efficient than our technology, are effective enough against target contaminants, and our “value-add” of also eliminating hard-to-treat micropollutants is not relevant unless regulations dictate that those chemicals must be removed. Similarly, the second application is only relevant in jurisdictions where those hard-to-treat micropollutants are regulated. Unfortunately, this does not include the US or Canada, but it does include several European countries. For that reason, presently, much of our business development efforts to secure projects for the AOS focus on development of partnerships to demonstrate the AOS for the European micropollutant market, or for domestic industrial or pharmaceutical wastewater treatment purposes where micropollutants are major contributors to facilities’ wastewater surcharge fees.

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. Preliminary internal testing has confirmed many of the technology's exceptional performance claims that make it an attractive battery technology for long duration energy storage, 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. These recent tests also helped verify 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. Once prototype batteries are built and tested, and assuming such tests show the batteries have the characteristics we expect would differentiate it from other battery technologies, we will complete the design on a larger sized battery cell that would then be incorporated into battery packs and battery sizes meant for industrial facilities. Once designed, our engineers will work to develop manufacturing processes that would allow scale production to ensure costs of goods in line with market demand and conditions. We are working to obtain technology validation from an independent organization that we believe will serve as a key milestone to the more rapid advancement of our commercial efforts.

We believe our Cellinity batteries will have features that far surpass comparable lithium-ion batteries, the dominant incumbent technology in the market, including:

• 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
• Increased energy efficiency and energy density in comparison to lithium-ion batteries, and a longer useful life expectancy of at least 10 years and expected to be up to 20 years or more

Our battery has high energy density and high voltage, making it well-suited for large format long duration energy storage rather than mobile energy storage purposes like EVs. Its electrical performance metrics also make it well-suited for long duration storage, meaning batteries which expend their electricity over up to ten hours, rather than being limited to two- or four-hour expenditures like many lithium-ion batteries. Such batteries are sought after for grid-scale leveling, storage of renewable energy, and emergency power redundancy purposes.

We are exploring multiple opportunities to commercialize our proprietary liquid sodium 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 on the table 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 is working closely with a medical device and cosmetics manufacturer founded over 50 years ago, Keystone Industries, to manufacture its products at scale. Keystone has invested over $3 million in equipment and infrastructure in its manufacturing facilities. Clyra has invested over $2 million in molds, equipment and resources to support scale manufacturing. Clyra has recently formalized relationships with multiple wholesale distributors and sales agents, and has the infrastructure in place to support their efforts to sell Clyra’s products to the medical industry. Clyra’s management team includes Chief Medical Officer Dr. Steven J. Kavros, a twenty-year veteran of the Mayo Clinic in roles such as Director at the Rochester Mayo Clinic’s Gonda Vascular Wound Healing Center, Nick Valeriani, who enjoyed 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 74% as of March 31, 2025 and December 31, 2024). 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 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 & 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 & 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 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.

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.

Results of Operations

Our revenues decreased 31% in the three months ended March 31, 2025, as compared with the same period 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”, which comprised 79% of our consolidated revenues. Our financial statements separate revenue based on products and services. Revenues from the sale of products for the three months ended March 31, 2025, decreased 39% over the same period in 2024. Revenues from services for the three months ended March 31, 2025, increased 152% over the same period in 2024.

ONM Environmental

Our wholly-owned subsidiary ONM Environmental generates revenues through (i) sales of our flagship product CupriDyne Clean, including related design, installation, and maintenance services on the systems that deliver CupriDyne Clean at its clients’ facilities, and (ii) sales of private-label products to third parties, including the Pooph branded pet odor control product.

Revenue (ONM Environmental)

ONM Environmental’s revenues decreased 39% (to $2,803,000) in the three months ended March 31, 2025, compared with the same period 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. Because the brand has only been on the market for three years, it is difficult to identify trends and uncertainties in sales volumes, especially so for longer periods of time. For the three months ending June 30, 2025, we expect a decrease in ONM Environmental's revenues as compared with the same period in 2024.

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, 2025, were 54% an increase of 1%, compared to the same period in 2024. The increase in cost of goods is consistent with the Pooph-branded product volume.

Selling, General and Administrative Expense (ONM Environmental)

ONM Environmental’s selling, general and administrative expenses ("SG&A") decreased 1% during the three months ended March 31, 2025, as compared with the same period in 2024. ONM Environmental's selling, general and administrative expenses are expected to remain consistent.

Operating Income (ONM Environmental)

ONM Environmental generated operating income of $956,000 in the three months ended March 31, 2025, compared to operating income of $1,798,000 for the three months ended March 31, 2024. The operating income for both periods was entirely dependent on the sale of Pooph branded products.

BLEST (engineering)

Revenue (BLEST)

Our engineering segment's (BLEST's) revenues increased 152% (to $466,000), in the three months ended March 31, 2025, as compared with the same period in 2024. The increase in revenue in the three months ended March 31, 2025, is related to the new contracts to provide air quality control compliance services to additional U.S. Air Force bases, increasing its ongoing contract-based revenue to approximately $100,000 per month. These ongoing contracts are expected to continue provide a monthly base revenue, in addition to regular work for other clients.

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, 2025, intersegment revenue for BLEST totaled $224,000 and for the three months ended March 31, 2024, intersegment revenue for BLEST totaled $171,000.

Cost of Revenues (BLEST)

BLEST’s cost of revenues includes employee labor, subcontracted costs and material costs. In the three months ended March 31, 2025, costs were 58% of revenues, versus 40% in the same period in 2024. The increase is related to increased costs on fixed fee contracts, compared to product sales attributed to the AEC project in Lake Stockholm New Jersey.

Selling, General and Administrative Expense (BLEST)

BLEST’s SG&A expenses were $330,000, in the three months ended March 31, 2025, compared to $203,000, in the three months ended March 31, 2024, the increase is due to additional employees. In June and July 2024, BLEST hired four additional full-time employees.

Operating Loss (BLEST)

BLEST incurred an operating loss of $378,000 in the three months ended March 31, 2025, compared to an operating loss of $445,000 in the three months ended March 31, 2024. This operating loss is reflective of the focus at BLEST on advancing internal BioLargo projects such as the Cellinity battery and AEC water treatment system. Our consolidated financial statements eliminate intersegment revenues. The decrease in operating loss was due to an increase in third party-revenues. Because BLEST had an operating loss, we invested cash during the quarter to maintain operations.

Clyra Medical

Clyra Medical has not yet begun commercial sales of its products and thus did not generate revenues in the three months ended March 31, 2025 or 2024. Historical revenues have been nominal. In the three months ended March 31, 2025, it incurred total costs and expenses of $1,315,000, which included $335,000 in research and development expenses. In the same period in 2024, total costs and expenses were $545,000, which included $121,000 in research and development expenses. The increases in costs and expenses is primarily related stock option expense recorded as selling, general and administrative expenses and product development costs. Management is not yet in a position to disclose when it believes Clyra will begin generating revenue.

BETI

BioLargo Energy Technologies, Inc. (BETI) is developing our Cellinity battery, and has not generated generate revenue. For the three months ended March 31, 2025, it incurred total costs and expenses of $94,000, which included $60,000 in research and development expenses. In the same period in 2024, total costs and expenses were $155,000, which included $80,000 in research and development expenses. We do not expect BETI to generate revenue in the near future as it continues its research and development activities.

BEST

BioLargo Equipment, Sciences and Technologies, Inc. (BEST) was formed in 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, 2025 and 2024 BEST incurred $58,000 and $66,000 in total expenses primarily related to sales and marketing 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, 2025 consolidated SG&A increased 15% (to $2,559,000). The largest components of our SG&A expenses included (in thousands):

In the three months ended March 31, 2025, our non-cash expenses from the issuance of stock and stock options totaled $712,000 compared to $623,000 for the three and nine months ended March 31, 2024. This increased due to stock option issuances for previously issued stock options that expired during the three months ended March 31, 2025. The majority of this stock option expense is recorded in Consulting expense. Salaries and payroll related expense increased due to the addition of new employees; companywide, there are 44 full time employees. Professional fees decreased due less corporate activity related to new subsidiaries, private securities offerings for BioLargo and Clyra, and other organizational needs that required professionals. Investor relation expense decreased due to fewer trade show and investor events.

Research and Development

In the three months ended March 31, 2025, we spent $791,000 in the research and development of our technologies and products, of which $335,000 was through Clyra Medical. This was an increase of 1% and compared to the three months ended March 31, 2024. The increase is primarily due to work related preparing for (i) the commercialization of medical products, to (ii) the battery project, and (iii) the AEC. As these products mature, we expect the level of research and development to continue.

Interest expense

Our interest expense for the three months ended March 31, 2025, was $65,000 compared to interest expense of $12,000 in the three months ended March 31, 2024. The increase of interest expense is related to the Clyra Medical note payables related to capital expenditures.

Other Income and Expense

For three months ended March 31, 2025 and 2024, we had $6,000 and $0 of grant income. 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 financial statements.

Net Loss

Net loss for the three months ended March 31, 2025, was $1,921,000 a loss of $ (0.004) per share, compared to a net loss for the three months ended March 31, 2024, of $775,000, a loss of $ (0.001) per share. Our net loss for the three ended March 31, 2025, increased because of the decrease in revenue.

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

Clyra’s net loss in due primarily to the expense associated with its efforts to launch products and build infrastructure to support sales activities.

Liquidity and Capital Resources

For the three months ended March 31, 2025, we generated revenues of $3,269,000 and had a net loss of $1,921,000. As of March 31, 2025, we had current assets of $7,218,000, of which $2,564,000 was cash and cash equivalents. For the three months ended March 31, 2025, we used $1,830,000 net cash used in operating activities. Our cash decreased $984,000 from December 31, 2024, and we had an increase of $1,077,000 in accounts receivable. As of March 31, 2025, we had current liabilities of $3,373,000, and working capital of $3,845,000. We and our partially owned subsidiaries continue to sell securities to ensure available working capital. We do not believe gross profits in the year ending December 31, 2025 will be sufficient to fund our current level of operations. We have been, and anticipate that we will continue to be, limited in terms of our capital resources, and expect to continue to need further investment capital to fund our business plans and investments in our new technologies. During the three months ended March 31, 2025, we and our subsidiaries received $885,000 from financing activities, including sales of stock and the issuance of note payables. The foregoing factors raise substantial doubt about our ability to continue as a going concern, unless we are able to (i) continue to increase revenues, generate cash from operations, and/or generate cash from financing activities, (ii) convert assets such as our $4,208,000 in accounts receivable into cash; or, (iii) if necessary, reduce ongoing cash obligations by curtailing portions of our operations. The 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, 2024, 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.

We conducted an evaluation, under the supervision and with the participation of management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended – the “Exchange Act”) as of the end of the period covered by this Report. There were no changes in our internal control over financial reporting during the quarter ended March 31, 2025, which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Our procedures have been designed to ensure that the information relating to our company, including our consolidated subsidiaries, required to be disclosed in our SEC reports is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow for timely decisions regarding required disclosure. However, our Company is continuing to grow and evolve, as our product and services sales continues to grow, and as we diversify our clients to include municipalities, increasing strain on our accounting systems. These activities put stress on our overall controls and procedures. We do not yet have the resources to implement the more sophisticated control systems used by larger companies. Although we have made some improvements, our chief executive officer and chief financial officer have concluded that, as of the evaluation date, our disclosure controls and procedures were not effective, due to the material weakness identified below.

It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Under the supervision and with the participation of our management, including our chief executive officer and the chief financial officer, we have established internal control procedures in accordance with the guidelines established in the 2013 Framework —Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Management evaluated the effectiveness of our internal controls, and concluded that due to our limited financial and personnel resources, the fact that we operate our business in three distinct locations in the U.S. and Canada, and the lack of sophisticated reporting systems, we continue to have a material weakness in our internal controls with respect to the closing our financial statements. Until the Company has the financial resources to implement more robust automated systems, or to hire additional dedicated accounting personnel, we expect this material weakness to continue.

Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls or our internal control over financial reporting, or any system we design or implement in the future, will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.
