Current report
Significant developments resulting from recent and potential changes in United States tariff policies could have a material adverse effect on us***.***
Current report
Beginning in the first quarter of 2025, the current U.S. presidential administration has imposed tariffs on various goods from various countries, including the European Union (“EU”), and has announced intentions to impose further significant tariffs on certain United States imports. The administration relied on the U.S. International Emergency Economic Powers Act (IEEPA) as the statutory basis for its authority to impose most of such tariffs. However, on February 20, 2026, the U.S. Supreme Court ruled that the IEEPA did not grant the president authority to impose tariffs, rendering such previously imposed tariffs invalid. Following the Supreme Court’s decision, the U.S. administration announced its intention to invoke other laws to impose tariffs by executive order and thereafter imposed new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. We rely on suppliers operating in, and exporting from, the EU, including our exclusive supplier of the filtration materials and technology used in certain of our filtration products. To the extent that tariffs and other restrictions imposed by the United States increase the price of, or limit the amount of, materials and finished goods imported into the United States, the costs of our materials, which we may be unable to pass onto customers, may be adversely affected, which could adversely affect our revenues and profitability. We cannot predict the effect these and potential additional tariffs will have on our supplier and our business, including in the context of escalating trade tensions. Further tariffs, additional taxes, or trade barriers, both domestically and internationally, may affect our costs and margins, the competitiveness of our products, and our ability to sell products or purchase necessary equipment and supplies, and consequently materially and adversely affect our business, results of operations, and financial conditions.
Current report
We rely on both employees and third-party contractors to install and service our water filtration products, and any failure by these parties to perform adequately could adversely affect our business and reputation.
Current report
The proper installation and servicing of our water filtration products are critical to ensuring their performance, safety and regulatory compliance. We rely on employees and third-party contractors and service providers to install and service our water filtration products. These contractors are not our employees, and we have limited control over the quality, timeliness, and consistency of their work. Their performance is influenced by factors that may be beyond our control, including the availability and training of their personnel. If we or our third-party service providers fail to perform installation or service work to our standards or to our customers’ expectations, our products may not function as intended, our reputation and customer satisfaction may be harmed. Poor workmanship or noncompliance with our installation and servicing specifications or applicable regulations could result in product malfunctions, water quality issues, property damage, customer complaints, personal injury, or other claims against us. Such failures could also expose us to increased warranty claims, as well as costs associated with corrective actions, replacements, or recalls. In addition, even isolated incidents of improper installation or servicing – whether caused by us or by third-party providers engaged by us – could negatively impact our brand and reputation, leading to reduced repeat or referral sales. Any of these outcomes could materially and adversely affect our reputation, results of operations, and financial condition.
Current report
We have identified a material weakness in our internal control over financial reporting. If we are unable to remediate this material weakness, or if we identify additional material weaknesses in the future or otherwise fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and the value of our common stock.
Current report
In connection with the preparation of our financial statements as of and for the quarterly period ended March 31, 2025, we identified a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis. Specifically, our management concluded that we had designed or maintained effective controls to ensure that we properly recognize revenue from service-based sales contracts. See “PART II – Item 9A. Controls and Procedures” in this Annual Report.
Current report
Although these items did not result in a material misstatement to our financial statements, this material weakness could have resulted in a material misstatement to our annual or interim financial statements that would not be prevented or detected. While we are designing and implementing measures to remediate our existing material weakness, we cannot predict the success of such measures. Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business, personnel, information technology systems or other factors. If we fail to remediate our existing material weakness or identify new material weaknesses in our internal control over financial reporting, or if we are unable to conclude that our internal control over financial reporting is effective, it is possible that a material misstatement of our financial statements would not be prevented or detected on a timely basis, investors may lose confidence in the accuracy and completeness of our financial reports, and the value of our common stock could be materially and adversely affected.
Reworded paragraphs (10)
Previous wording
We have a history of operating losses and a significant accumulated deficit, and we may not be able to maintain or improve our profitability in the future.
Current wording
We have only a limited history of profitability and a significant accumulated deficit, and we may not be able to maintain or improve our profitability in the future.
Previous wording
As of December 31, 2024, we had an accumulated deficit of $144.3 million as a result of prior historical operating losses. While we believe that revenues will increase following our expansion of the sales team in 2024, there can be no guarantee of this. We may continue to incur additional losses in the future depending on the timing and marketplace acceptance of our products and as a result of operating expenses being higher than our gross margin from product sales. We sold our first commercial product in March 2004, and the year ended December 31, 2024 was only our first profitable year in our history with net income of $0.1 million. Each of the following factors, among others, may influence the timing and extent of our profitability, if any:
Current wording
Although we have been profitable during each of the fiscal years ended December 31, 2024, and December 31, 2025, as of December 31, 2025, we had an accumulated deficit of $143.1 million as a result of prior historical operating losses. While our revenues have increased following our expansion of the sales team in both 2024 and 2025, there can be no guarantee our revenues will continue to grow. We may incur additional losses in the future depending on the timing and marketplace acceptance of our products and as a result of operating expenses being higher than our gross margin from product sales. Each of the following factors, among others, may influence our profitability:
Previous wording
Our business and future prospects are substantially dependent upon our ability to significantly grow our product revenue. Although our sales were approximately 43% higher in 2023 compared to 2022, our revenues declined slightly in 2024 compared to 2023. There is no assurance that we will be able to resume sales growth in future periods. Our ability to increase our revenues in future periods will depend on our ability to significantly grow our customer base and then consistently obtaining product reorders from those customers. If we cannot sustain significant revenue growth for an extended period, our financial results will be adversely affected, and our stock price may decline.

Previous wording
Companies in the United States and around the world may experience a disruption in the supply of certain components and raw materials, as happened during the worldwide pandemic starting in 2020. A disruption in such items as resins and polymers, could adversely affect us and our ability to obtain these components in a timely manner, in the volumes we require, or at all. In addition, the prices of these components and other supplies we rely upon in the manufacture of our products may rise. For example, we and our suppliers have recently experienced, and may continue to experience, rising costs due to inflation, such as costs of materials, labor and freight. If inflation continues to rise, the prices of our components may rise, resulting in increased expenses to us that we may not be able to offset by raising the prices of our products. In addition, with the change in U.S. presidential administration in January 2025, there is increased risk of new tariffs which could also affect the prices we pay for critical supplies and materials.

In exchange for the rights granted, we have agreed to make minimum annual aggregate purchases from Medica of €4,208,000, €4,629,000, €4,976,000, €5,349,000 and €5,750,000 for the years 2024, 2025, 2026, 2027 and 2028, respectively. We satisfied our minimum purchase obligations for 2024, but if we are unable to satisfy the minimum purchase commitments in future years, we may be in breach of the License and Supply Agreement, giving Medica a right of termination. If the License and Supply Agreement is terminated, we may be unable to obtain our filtration products from an alternative supplier on commercially favorable terms, if at all. If we are unable to obtain our filtration products from an alternative supplier, we may be unable to supply our products to our customers, which could have a material adverse effect on our results of operations and damage our reputation.

We operate our business with a two-person senior management team. We have a Chief Executive Officer and a Chief Financial Officer, who together directly oversee operations, sales and finances. Our dependence on two officers to perform multiple functions exposes us to various risks, including the risk that two officers may be unable to devote sufficient or timely attention to all aspects of operating our business and that in the event of a sudden departure of one officer, we may not be able to promptly identify a successor. We do not carry key person life insurance on any of our employees. If we are unable to recruit and retain qualified personnel to our senior management teams, we will be unlikely to achieve our objectives of continuing to grow our company and our business may otherwise be harmed.

During the two years ended December 31, 2024, our common stock has traded at prices ranging from a high of $4.04 to a low of $0.95 per share. Due to the lack of an active trading market for our common stock, we expect the prices at which our common stock might trade to continue to be highly volatile. The expected volatile price of our stock will make it difficult for investors to predict the value of an investment in our common stock, to sell shares at a profit at any given time, or to plan purchases and sales in advance. A variety of other factors might also affect the market price of our common stock. These include, but are not limited to:

In the past we have issued common stock and warrants in order to raise capital to help fund our business. We have also issued stock options and restricted stock as compensation for services and incentive compensation for our employees, directors, and consultants. We have shares of common stock reserved for issuance upon the exercise of certain of these securities and may increase the shares reserved for these purposes in the future. Our issuance of additional common stock, options and warrants could affect the rights of our stockholders, could reduce the market price of our common stock, or could obligate us to issue additional shares of common stock.
Current wording
In the past we have issued common stock and warrants in order to raise capital to help fund our business. We have also issued stock options and restricted stock as compensation for services and incentive compensation for our employees, directors, and consultants, and we have previously issued shares of our common stock as consideration for acquiring other businesses. We have shares of common stock reserved for issuance upon the exercise of certain of these securities and may increase the shares reserved for these purposes in the future. Our issuance of additional common stock, options and warrants could affect the rights of our stockholders, could reduce the market price of our common stock, or could obligate us to issue additional shares of common stock.

Previous wording
As of March 1, 2025, Wexford, our largest stockholder, beneficially owned approximately 34% of our outstanding common stock. Collectively, Wexford, our directors and our executive officers beneficially owned approximately 37.5% of our outstanding common stock. As a result of this ownership, Wexford has the ability to exert significant influence over our policies and affairs, including the election of directors. Wexford, whether acting alone or acting with other stockholders, could have the power to elect all of our directors and to control the vote on substantially all other corporate matters without the approval of other stockholders. Furthermore, such concentration of voting power could enable Wexford, whether acting alone or acting with other stockholders, to delay or prevent another party from taking control of our company even where such change of control transaction might be desirable to other stockholders. The interests of Wexford in any matter put before the stockholders may differ from those of any other stockholder.
