ITEM 1A. RISK FACTORS

Investing in our common stock involves risks. Before investing in our common stock, you should consider carefully the factors discussed below and the information contained in this Annual Report. Each of these risks, as well as other risks and uncertainties not presently known to us or that we currently deem immaterial, could adversely affect our business, results of operations, cash flows and financial condition, and cause the value of our common stock to decline, which may result in the loss of part, or all, of your investment.

Our exclusive license to provide water to retail customers in the Cayman Islands is presently under renegotiation with OfReg, the Cayman Islands government utility regulatory authority, and we are presently unable to predict the outcome of these on-going negotiations.

We sell water through our retail operations under the 1990 license that granted Cayman Water the exclusive right to provide potable water to customers within its licensed service area. Pursuant to the 1990 license, Cayman Water has the exclusive right to produce potable water and distribute it by pipeline to its licensed service area, which consists of two of the three most populated areas of Grand Cayman Island: Seven Mile Beach and West Bay. In 2025, 2024, and 2023, we generated approximately 26%, 24% and 17%, respectively, of our consolidated revenue and 39%, 38% and 26%, respectively, of our consolidated gross profit from the retail water operations conducted under the 1990 license.

The 1990 license was originally scheduled to expire in July 2010 but was extended several times by the Cayman Islands government in order to provide the parties with additional time to negotiate the terms of a new license agreement. The most recent express extension of the license expired on January 31, 2018. From that date through February 18, 2025, we continued to operate under the terms of the 1990 license, treating such terms as operative notwithstanding the expiration of the express extension. We continued to pay a royalty of 7.5% of the revenue we collected as required under the 1990 license.

In October 2016, the Government of the Cayman Islands passed legislation which created OfReg and, in April 2017, passed supplemental legislation which transferred responsibility for the economic regulation of the water utility sector and the negotiations with us for a new retail license to OfReg.

Under the new regulatory legislation passed in October 2016, Cayman Water was required to first be granted a concession by the government before obtaining a new (or renewing the old) retail operations license. On February 18, 2025, Cayman Water received a new concession from the government that authorizes and maintains the terms of the 1990 license until a

Table of Contents

new license from OfReg is negotiated and enacted. Negotiations between Cayman Water and OfReg for the new license remain on-going.

We have been informed during our retail license negotiations, both by OfReg and its predecessor in these negotiations, that they seek to restructure the terms of the license in a manner that could significantly reduce the operating income and cash flows we have historically generated from our retail license. We are presently unable to determine what impact the resolution of our retail license negotiations will have on our consolidated financial condition, results of operations or cash flows but such resolution could result in a material reduction (or the loss) of the operating income and cash flows we have historically generated from our retail operations and could require us to record impairment losses to reduce the carrying values of our retail segment assets. Such impairment losses could have a material adverse impact on our consolidated financial condition and results of operations.

Periodically, our Bahamas subsidiary experiences substantial delays in the collection of its accounts receivable. As a result, our Bahamas subsidiary could have insufficient liquidity to continue operations, and our consolidated financial results could be materially adversely affected.

CW-Bahamas’ accounts receivable balances (which include accrued interest) due from the WSC amounted to $20.7 million and $28.4 million as of December 31, 2025 and 2024. Approximately 71% and 81% of the accounts receivable balances were delinquent as of those dates, respectively. As of February 28, 2026, this receivable amounted to $22.6 million, of which 75% was delinquent. The delay in collecting these accounts receivable has adversely impacted the liquidity of this subsidiary.

From time to time (including presently), CW-Bahamas has experienced delays in collecting its accounts receivable from the WSC. When these delays occur, we hold discussions and meetings with representatives of the WSC and the government of The Bahamas. All previous delinquent accounts receivable from the WSC, including accrued interest thereon, were eventually paid in full. Based upon this payment history, we have not provided for a material allowance for credit losses for CW-Bahamas’ accounts receivable from the WSC as of December 31, 2025, or prior periods.

We continue to be in frequent contact with officials of The Bahamas government, who continue to express their intention to significantly reduce CW-Bahamas’ delinquent accounts receivable balances. However, we are unable to determine when or if such reduction will occur.

In a report dated October 6, 2022, Moody’s Investor Services (“Moody’s”) downgraded The Bahamas’ long-term issuer and senior unsecured ratings to B1 from Ba3. Moody’s also lowered The Bahamas’ local currency ceiling to Baa3 from Baa2 and its foreign currency ceiling to Ba1 from Baa3. Moody’s has maintained these ratings through the date of its most current report issued in April 2025. Based upon our review of this Moody’s correspondence, we continue to believe that no material allowance for credit losses is required for CW-Bahamas’ accounts receivable from the WSC.

If CW-Bahamas is unable to collect a significant portion of its delinquent accounts receivable, one or more of the following events may occur: (i) CW-Bahamas may not have sufficient liquidity to meet its obligations; (ii) we may be required to cease the recognition of revenue on CW-Bahamas’ water supply agreements with the WSC; and (iii) we may be required to provide a material allowance for credit losses for CW-Bahamas’ accounts receivable. Any of these events could have a material adverse impact on our consolidated financial condition, results of operations, and cash flows.

The profitability of our contracts is dependent upon our ability to accurately estimate construction and operating costs.

The cost estimates we prepare in connection with the construction and operation of our water plants, the water infrastructure we construct and sell to third parties, and our manufacturing contracts, are subject to inherent uncertainties. Additionally, the terms of our water supply contracts may require us to guarantee the price of water on a per unit basis, subject to certain annual inflation and monthly energy cost adjustments, and to assume the risk that the costs associated with producing this water may be greater than anticipated. Because we base our contract prices in part on our estimation of future construction, manufacturing and operating costs, the profitability of our plants and our manufacturing and operations and maintenance contracts is dependent on our ability to estimate these costs accurately. The cost of materials

Table of Contents

and services and the cost of the delivery of such services may increase significantly after we submit our bid for a contract, which could cause the gross profit for a contract to be less than we anticipated when the bid was made. The profit margins we initially expect to generate from an operations and maintenance contract could be further reduced if future operating costs for that contract exceed our estimates of such costs. Any construction, manufacturing, and operating costs for our contracts that significantly exceed our initial estimates could have a material adverse impact on our consolidated financial condition, results of operations, and cash flows.

Substantial changes to fiscal, regulation and other federal policies could adversely affect our business, financial condition, operating results and cash flows.

Significant changes in, and uncertainty with respect to, legislation, regulation, government policy and economic conditions could adversely affect our business. Specific legislative and regulatory proposals that could have a material impact on us include, but are not limited to, modifications to international trade policy (such as tariffs); public company reporting requirements; and environmental regulation.

We cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the U.S. and other countries, what products may be subject to such actions, or what actions may be taken by the other countries in retaliation. Accordingly, it is difficult to predict how such actions may impact our business, or the business or habits of our customers. Our business operations, as well as the businesses of our customers on which we are substantially dependent, are located in countries at risk for escalating trade disputes, including the U.S. Any resulting trade wars could have a significant adverse effect on world trade and could adversely impact our consolidated financial condition, results of operations and cash flows.

Certain of PERC’s contracts with its customers, including the contract with the Board of Water Supply of the City of Honolulu, Hawaii, may be terminated at any time at the customer’s convenience or with relatively short advance notice. The termination of any of these contracts prior to their full performance may result in us realizing less than the full consideration payable under the contract and may negatively impact our financial results.

Certain of PERC’s contracts with its customers, and substantially all of its contracts with governments or municipalities, may be terminated at any time at the customer’s convenience with no or relatively short advance notice. Our business is highly dependent on the purchase of our products and services by government and municipalities, and we believe that contracts with similar termination provisions will continue to be a source of a substantial portion of our revenue for the foreseeable future.

If a customer terminates one of our contracts for convenience, we generally may recover, at most, our incurred or committed costs, settlement expenses, and payment for work completed or products delivered prior to the termination. As such, the termination of any of these contracts prior to their stated term may result in us realizing less than the full consideration payable under the contract. If any such contract is terminated prior to us performing a substantial portion of the work to be performed or delivering a substantial portion of the products to be delivered, prior to the termination, such termination may have a material adverse impact on our consolidated results of operations.

A significant portion of our consolidated revenue is derived from our water supply agreements with the WSC. The loss of the WSC as a customer would adversely affect us.

One bulk water customer, the WSC, accounted for approximately 22% of our consolidated revenue for 2025. If, for financial or other reasons, the WSC does not comply with the terms of our water supply agreements, our consolidated financial condition, results of operations, and cash flows could be materially adversely affected.

Our operations are affected by tourism and are subject to seasonal fluctuations and other factors beyond our control that could affect the demand for our water.

Demand for our water in the Cayman Islands and The Bahamas is affected by variations in the level of tourism and local weather, primarily rainfall. Tourism in our service areas is affected by the economies of the tourists’ home countries, primarily the United States and Europe, terrorist activity and perceived threats thereof, global health concerns such as

Table of Contents

COVID-19, and increased costs of fuel and airfare. In the Cayman Islands, we normally sell more water during the first and second quarters of the year, when the number of tourists is greater and local rainfall is less than in the third and fourth quarters. A downturn in tourism or greater than expected rainfall in the locations we serve could adversely impact our results of operations and cash flows. During the COVID-19 pandemic, the resulting cessation of tourism to the Cayman Islands through August 2022 significantly reduced the demand for our water and our retail segment’s profitability.

Performance shortfalls under any of our bulk supply contracts could result in penalties or cancellation of the contract.

Our bulk water supply agreements require us to meet specified minimum quality, quantity and energy consumption guarantees. Membrane fouling or other technical problems could occur at any of our plants, and if we are unable to meet the guarantees due to such technical problems, we could be in default of the supply agreement and subject to various adverse consequences, including financial penalties or cancellation of the agreement.

Our operations could be harmed by natural disasters such as hurricanes or earthquakes.

A natural disaster could cause major damage to our equipment and properties and the properties of our customers, including the large tourist properties in our areas of operation. For example, in January 2020, Grand Cayman experienced an earthquake which damaged three of our eight potable water storage tanks. Any future disaster could cause us to lose use of our equipment and properties and incur additional repair costs. Damage to our customers’ properties and the adverse impact on tourism could result in a decrease in water demand. A natural disaster could also disrupt the delivery of equipment and supplies, including electricity, necessary to our operations. These and other possible effects of natural disasters could have a material adverse impact on our consolidated financial condition, results of operations, and cash flows.

Contamination of our water may cause disruption in our services and adversely affect our revenue.

Our feed water and/or processed water may become contaminated by natural occurrences and by inadvertent or intentional human interference, including acts of terrorism. If our feed water and/or processed water becomes contaminated, we may have to interrupt our supply of desalinated potable water until we are able to install treatment equipment or substitute the flow of water from an uncontaminated water source. In addition, we may incur significant costs in order to treat contaminated feed or processed water through expansion of our current treatment facilities, or development of new treatment methods. An inability by us to substitute feed water from an uncontaminated water source or to adequately treat the contaminated plant feed water or our processed water in a cost-effective manner may have a material adverse impact on our consolidated financial condition, results of operations, and cash flows.

Potential government decisions, actions and regulations could negatively affect our operations.

We are subject to the local regulations of the countries in which we operate, all of which are subject to change. Any government that regulates our operations may issue legislation or adopt new regulations, including but not limited to:

●restricting foreign ownership (by us);

●providing for the expropriation of our assets by the government;

●providing for nationalization of public utilities by the government;

●providing for different water quality standards;

●unilaterally changing or renegotiating our license and agreements;

●restricting the importation or use, and/or imposing tariffs on certain goods and materials from foreign countries;

●restricting the transfer of U.S. currency; or

●causing currency exchange fluctuations/devaluations or enacting changes in tax laws.

As new laws and regulations are issued, we may be required to modify our operations and business strategy, which we may be unable to do in a cost-effective manner. Failure by us to comply with applicable regulations could result in the loss of our authorizations to operate, the assessment of penalties or fines, or otherwise may have a material adverse impact on our consolidated financial condition, results of operations and cash flows.

Table of Contents

Unforeseen environmental costs could adversely affect our business and results of operations.

We are subject to various federal, state, local and foreign laws and regulations concerning environmental protection, including laws addressing water quality and contamination, the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, and the cleanup of contaminated sites. In particular, we face increasing complexity in our operations as we adjust to new and future requirements relating to water quality, the composition of our other products, their safe use, the energy consumption associated with our operations, and climate change laws and regulations. If we were to violate or become liable under environmental laws or if our products become non-compliant with environmental laws, we could incur substantial costs or face other sanctions, which may include restrictions on operating in certain jurisdictions. Our potential exposure includes fines and civil or criminal sanctions, third-party property damage, personal injury claims and clean-up costs. Further, liability under some environmental laws relating to contaminated sites can be imposed retroactively on a joint and several basis, and without any finding of noncompliance or fault. The amount and timing of costs to comply with environmental laws are difficult to predict. In addition, any complaints or lawsuits against us based on water quality and contamination may receive negative publicity that can damage our reputation and adversely affect our business and trading price of our common stock.

If we fail to abide by laws, rules and regulations relating to human and workers’ rights, we could be subject to various actions and our reputation, business and financial results could be adversely affected.

We are subject to various federal, state, local and foreign laws and regulations concerning human rights, including laws prohibiting discrimination, harassment, and forced or child labor, and establishing wage and hour standards. If we were to violate or become liable under human or workers’ laws, we could incur substantial costs or face other sanctions. Our potential exposure includes fines and civil or criminal sanctions or liability. The amount and timing of costs to comply with human and workers’ rights laws are difficult to predict. Additionally, the success of our business depends on earning and maintaining the trust and confidence of our customers, suppliers, stockholders and the communities in which we operate, our ability to compete for future opportunities, and our reputation among existing and potential clients and partners. Our reputation is critical to our business and could be impacted by events that may be difficult or impossible to control, and costly or impossible to remediate. For example, alleged or actual failures by us or our employees to comply with applicable human or workers’ rights laws, rules or regulations, expectations and perceptions of our employment and environmental, social and governance practices, threatened or actual litigation against us or our employees, or the public announcement and potential publicity surrounding any of these issues, even if inaccurate, satisfactorily addressed, or if no violation or wrongdoing actually occurred, could adversely impact our reputation and relationships with customers, suppliers, stockholders and the communities in which we operate, and our ability to renew or negotiate new agreements for projects. Any such failure or reputational harm could have an adverse effect on our consolidated financial condition, results of operations and cash flows.

We rely on the efforts of key employees. Our failure to retain these employees could adversely affect our results of operations.

Our success depends upon the abilities of our Executive Officers. In particular, the loss of the services of Frederick W. McTaggart, our President and Chief Executive Officer, could be detrimental to our operations and our continued success. Mr. McTaggart has an employment agreement expiring on December 31, 2028. Each year, the term of this agreement may be extended for an additional year. However, we cannot guarantee that Mr. McTaggart will continue to work for us during the term of his agreement or will extend his employment agreement with us.

Our business could be adversely affected by cyber threats or other interruptions in information technology, communications networks and operations.

As part of our operations, we rely on computer systems to process transactions and communicate with our customers, suppliers and other third parties. We rely on continued and unimpeded access to secure network connections to communicate between locations and on reliable internet connections to communicate with external parties. We have physical, technical and procedural safeguards in place that are designed to protect information and protect against security and data breaches as well as fraudulent transactions and other activities. Despite these safeguards and our other security processes and protections, we cannot be assured that all our systems and processes are free from vulnerability to evolving

Table of Contents

and increasingly sophisticated cyber-attacks, to other physical breaches or to inadvertent data disclosure by third parties or by us. A significant data security breach, including misappropriation of customer, supplier or confidential employee information, could cause us to incur significant costs, which may include potential costs of investigations, legal, forensic and consulting fees and expenses, costs and diversion of management attention required for investigation, remediation and litigation, substantial repair or replacement costs. We could also experience data losses that would impair our ability to manage our business operations, including accounting and project costs, manage our water and distribution systems or process transactions and have a negative impact on our reputation and loss of confidence of our customers, suppliers and others, any of which could have a material adverse impact on our consolidated financial condition, results of operations, and cash flows and our business in general.

We are exposed to credit risk through our relationships with several customers.

We are subject to credit risk posed by possible defaults in payment by our customers in the Cayman Islands, The Bahamas, the United States, and the British Virgin Islands. Adverse economic conditions affecting, or financial difficulties of, those parties could impair their ability to pay us or cause them to delay payment. We depend on these parties to pay us on a timely basis. Our outstanding accounts receivable are not covered by collateral or credit insurance. Any delay or default in payment could adversely affect our consolidated financial condition, results of operations, and cash flows.

We are exposed to the risk of variations in currency exchange rates.

Although we report our results in United States dollars, a significant portion of our revenue is earned in other currencies. These currencies have been fixed to the United States dollar for more than 50 years. Consequently, we do not employ hedging strategies against the foreign currency exchange rate risk associated with conducting business in foreign currencies while reporting in United States dollars. If any of the existing fixed exchange rates for these other currencies becomes a floating exchange rate and any of these currencies depreciate against the U.S. dollar, our consolidated financial condition, results of operations, and cash flows could be materially adversely affected.

We may not pay dividends in the future. If dividends are paid, they may be in lesser amounts than past dividends.

Our shareholders may receive dividends out of legally available funds if, and when, they are declared by our Board of Directors. We have paid dividends in the past but may cease to do so at any time. We may incur increased operating or development expenses or capital requirements or indebtedness in the future that may restrict our ability to pay dividends. We may also be restricted from paying dividends in the future due to restrictions imposed by applicable corporate laws, our consolidated financial condition, results of operations and cash flows, covenants contained in financing agreements, and other factors considered by our Board of Directors. We may not continue to pay dividends in the future or, if dividends are paid, they may not be in amounts comparable to past dividends.

Service of process and enforcement of legal proceedings commenced against us in the United States may be difficult to obtain.

We are incorporated under the laws of the Cayman Islands and most of our assets are located outside of the United States. In addition, as of March 9, 2026, six of our 15 Directors and Officers reside outside the United States. As a result, it may be difficult for investors to execute service of process within the United States upon us and such other persons, or to enforce judgments obtained against such persons in United States courts, and bring any action, including actions predicated upon the civil liability provisions of the United States securities laws. In addition, it may be difficult for investors to enforce, in original actions brought in courts or jurisdictions located outside of the United States, rights predicated upon the United States securities laws.

Based on the advice of our Cayman Islands legal counsel, we believe no reciprocal statutory enforcement of foreign judgments exists between the United States and the Cayman Islands, and that foreign judgments originating from the United States are not directly enforceable in the Cayman Islands. A prevailing party in a United States proceeding against us or our Directors and Officers would have to initiate a new proceeding in the Cayman Islands using the United States judgment as evidence of the party’s claim. A prevailing party could rely on the summary judgment procedures available in the Cayman Islands, subject to available defenses in the Cayman Islands courts, including, but not limited to, the lack

Table of Contents

of competent jurisdiction in the United States courts, lack of due service of process in the United States proceeding and the possibility that enforcement or recognition of the United States judgment would be contrary to the public policy of the Cayman Islands.

Depending on the nature of damages awarded, civil liabilities under the Securities Act of 1933, as amended (or the Securities Act), or the Securities Exchange Act of 1934, as amended (or the Exchange Act), for original actions instituted outside the Cayman Islands may or may not be enforceable. For example, a United States judgment awarding remedies unobtainable in any legal action in the courts of the Cayman Islands, such as treble damages, would likely not be enforceable under any circumstances.

The relatively low trading volume of our stock may adversely impact the ability to sell our shares.

The average daily trading volume of our common stock in 2025 was approximately 113,000 shares, a much lower trading volume than that of many other companies listed on the NASDAQ Global Select Market. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the market of willing buyers and sellers of our common stock at any given time. This presence in turn depends on the individual decisions of investors and general economic and market conditions over which we have no control. Due to the limited volume of trading in our common stock, an investor in our stock may have difficulty selling larger volumes of our common stock in the manner, or at the price, that might be attainable if our common stock were more actively traded.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

Cybersecurity Risk Management and Strategy

Our information technology (“IT”) and cybersecurity programs are crucial to maintaining secure operations, which enable us to deliver on our promise to customers and maintain stakeholder trust. Our Vice President of Information Technology (“VP IT”) is responsible for establishing, implementing, and executing our cybersecurity program and strategy.Our VP IT has more than 25 years of IT, IT audit, and cybersecurity experience, and is involved in assessing the latest developments in cybersecurity, including potential threats and innovative risk management techniques. All IT staff are obliged to include cybersecurity as part of their everyday considerations and tasks.

Our cybersecurity program is a critical component of our enterprise risk management process overseen by our Board of Directors, and we have integrated cybersecurity-related risks into our overall enterprise risk management framework. Additionally, cybersecurity-related risks are included in the risk universe that the risk management function evaluates to assess top risks to the enterprise on an annual basis.

Our IT department proactively identifies, manages, and mitigates cyber risk in a variety of ways, including but not limited to:

a. A formal enterprise-wide cybersecurity policy and related standards;

b. Cybersecurity training and employee phishing simulations;

c. Ongoing vulnerability assessment, identification, and remediation;

d. Cyber incident response, IT disaster recovery, and business continuity plans;

e. Identity and access management controls;

f. Automated patch management and security updates;

g. Network isolation of key operations environments; and

h. Email filtering with attachment inspection and targeted threat protection.

The standards set in our cybersecurity program include the implementation of controls that are aligned with industry guidelines and applicable regulations to identify threats, deter attacks, and protect our information security assets. These standards are guided, in part, by the relevant National Institute of Standards and Technology (NIST) and American Water

Table of Contents

Works Association (AWWA) frameworks and guidance. We use various tools, security measures and technologies to aid in seeking to protect our network perimeter and internal systems from unauthorized access, intrusion, or disruption. Assessments are conducted across our systems, networks, and data infrastructure to identify potential cybersecurity threats and vulnerabilities.

We have policies and procedures in place for selecting and managing our relationships with third-party service providers and other business partners, including monitoring compliance with our agreements and regulatory and legal requirements. We also actively engage with industry participants and related communities as part of our continuing efforts to evaluate and enhance the effectiveness of our information security policies and procedures. In addition, a monitoring and detection system has been implemented to help identify cybersecurity threats and incidents. Our cybersecurity program also focuses on providing training and awareness to our employees and contractors on cybersecurity best practices.

Cybersecurity Governance

Our Board of Directors considers cybersecurity risk as part of its risk oversight function and has delegated to the Audit Committee oversight of cybersecurity and other IT risks. The Audit Committee oversees management’s implementation of our cybersecurity risk management program.

The Audit Committee oversees the management of our cybersecurity risk exposures and the steps management has taken to monitor and control such exposures. At each quarterly meeting, the Audit Committee receives an update from our VP IT and other members of management on relevant topics, including cybersecurity program maturity progress, new capabilities implemented, testing results, key cyber risk metrics (e.g., simulated phishing testing and vulnerability management) and notable incidents or events should they occur. On an annual basis, our Board of Directors meets with our VP IT and our third-party cybersecurity consultant to review our cybersecurity strategy. In accordance with our cybersecurity incident response plan, our Board of Directors is promptly informed of potentially material cybersecurity incidents, including with respect to our third-party service providers.

Although we have experienced cybersecurity incidents from time to time that have not had a material adverse effect on our business, financial condition, or results of operations, there can be no assurance that a cyber-attack, security breach, or other cybersecurity incident will not have a material adverse effect on us in the future.

Our management team supervises efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in the IT environment.

For a discussion regarding risks from cybersecurity threats that have or are reasonably likely to affect the company, see the risk factor titled “Our business could be adversely affected by cyber threats or other interruptions to information technology, communications networks and operations.” in Item 1A of this Annual Report on Form 10-K.

ITEM 2. PROPERTIES

Cayman Islands Properties

a warehouse, workshop and offices. It is located on land owned by the WSC and our 20-year water sales agreement gives us a license to use the land throughout the term of that agreement.

The Blue Hills plant water supply agreement was amended in January 2011 and extended through 2032. Pursuant to this amendment, we added a second production facility to increase the total production capacity of the Blue Hills plant to 12.0 million gallons per day. The second facility was completed in March 2012 and is powered by a combination of diesel engine-driven high-pressure pumps and electrical power purchased from Bahamas Power and Light to power all other loads in the plant. The second facility is contained within a steel building with a footprint of 10,640 square feet located adjacent to the initial production facility on land owned by the WSC. We also own and maintain a 1.0 million gallon welded steel elevated water storage tank that was constructed by us and is operated by the WSC.

U.S. Properties

Aerex owns a manufacturing facility situated on 6.4 acres of land in Fort Pierce, Florida. In August 2025, we completed an expansion of this facility that increased its total manufacturing space to 47,500 square feet. Aerex also leases approximately 6,000 square feet of office space in downtown Fort Pierce under a lease that expires on June 30, 2026. We expect to renew this lease on a short-term basis while new office space is constructed on the manufacturing site, with construction scheduled to begin at the end of 2026.

Our Aquilex warehouse consists of 4,100 square feet located in Sunrise, Florida that has been leased through September 2030. Our Aquilex office consists of 6,500 square feet located in Coral Springs, Florida that has been leased through June 2031.

Cayman Islands

We have been operating our business on Grand Cayman since 1973 and have been using reverse osmosis technology to convert seawater to potable water since 1989. The Cayman Islands have a limited natural supply of fresh water. We have an exclusive license from the Cayman Islands government to process potable water from seawater and then sell and distribute that water by pipeline to the Seven Mile Beach and West Bay areas of Grand Cayman. Our Grand Cayman operations consist of three company-owned seawater reverse osmosis desalination plants which (as of December 31, 2025) provide water to 8,717 retail residential and commercial connections within a government licensed area and three government-owned seawater reverse osmosis plants which supply bulk water to the WAC. Our pipeline system on Grand Cayman Island covers the Seven Mile Beach and West Bay areas of Grand Cayman and consists of approximately 100 miles of potable water pipe.

Our exclusive license from the Cayman Islands government was originally scheduled to expire in July 2010 but was extended several times by the Cayman Islands government in order to provide the parties with additional time to negotiate the terms of a new license agreement. The most recent express extension of the license expired on January 31, 2018. From that date to February 18, 2025, we continued to operate under the terms of the 1990 license, treating such terms as operative notwithstanding the expiration of the express extension. We continued to pay a royalty of 7.5% of the revenue we collect as required under the 1990 license. On February 18, 2025, Cayman Water received a new concession from the government that authorizes and maintains the terms of the 1990 license until a new license from OfReg is negotiated and enacted. Negotiations between Cayman Water and OfReg for the new license remain on-going.

The Bahamas

CW-Bahamas produces potable water from two seawater reverse osmosis desalination plants. The Windsor plant and the Blue Hills plant are located in Nassau, New Providence and have a total installed capacity of 14.8 million gallons per day. CW-Bahamas supplies water from these plants to the WSC under long-term supply agreements. During 2025, we supplied approximately 4.8 billion gallons of water to the WSC from these plants, which is consistent with the 4.8 billion gallons supplied during 2024.

From time to time (including presently), CW-Bahamas has experienced delays in collecting its accounts receivable. Representatives of the Bahamas government have informed us that their delays in paying our accounts receivables did/do not reflect any type of dispute with us with respect to the amounts owed. To date, all amounts due from CW-Bahamas were eventually paid in full, and we believe that the present accounts receivable from the WSC are fully collectible. Such accounts receivable balances due from The Bahamas government amounted to $20.7 million as of December 31, 2025. See further discussion of this matter at ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - LIQUIDITY AND CAPITAL RESOURCES - CW-Bahamas Liquidity.

Critical Accounting Policies and Estimates

Our critical accounting policies relate to (i) the valuations of our goodwill, intangible assets and long-lived assets; and (ii) revenue recognition on our construction and manufacturing contracts.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Our actual results could differ significantly from such estimates and assumptions.

Table of Contents

The application of our critical accounting policies involves estimates or assumptions that constitute “critical accounting estimates” for us because:

Goodwill and Intangible Assets

Goodwill represents the excess cost of an acquired business over the fair value of the assets and liabilities of the acquired business as of the date of acquisition. Goodwill and intangible assets recorded as a result of a business combination and determined to have an indefinite useful life are not amortized but are tested for impairment annually or upon the identification of a triggering event. Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed periodically for impairment. We evaluate the possible impairment of goodwill annually as part of our reporting process for the fourth quarter of each fiscal year. Management identifies our reporting units for goodwill impairment testing purposes, which consist of Cayman Water, the bulk segment (which is comprised of CW-Bahamas and OC-Cayman), PERC, REC, and the manufacturing segment (i.e., Aerex), and determines the carrying value of each reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets, to those reporting units. We determine the fair value of each reporting unit and compare these fair values to the carrying amounts of the reporting units. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit, an impairment loss is recorded.

For 2025 and 2024, we elected to assess qualitative factors to determine whether it was necessary to perform the quantitative goodwill impairment testing we have conducted in prior years for our reporting units. We assessed the relevant events and circumstances to evaluate whether it is more likely than not that the fair values of such reporting units are less than their carrying values. The events and circumstances assessed for each reporting unit included macroeconomic conditions, industry and market conditions, cost factors, overall financial performance, and other relevant events. Based upon this qualitative assessment, we determined that it is more likely than not that the fair values of our reporting units exceeded their carrying values as of December 31, 2025 and 2024.

In late July 2021, a major customer communicated to Aerex that its purchases of a specialized product from Aerex in 2022 and subsequent years would be at substantially reduced annual amounts, as compared to the amounts it had purchased from Aerex in prior years. As a result, our updated sales estimate for this customer based on this new information was substantially below the sales we anticipated to this customer for 2022 and subsequent years that we used in the discounted cash flow projections we prepared for purposes of testing our manufacturing reporting unit’s goodwill for possible impairment as of December 31, 2020. Furthermore, Aerex’s efforts to replace the revenue previously generated from this customer with revenue from existing and new customers were adversely impacted by negative economic conditions (caused in part by the COVID-19 pandemic). These negative economic conditions also increased Aerex’s raw material costs, resulted in raw material shortages and extended delivery times for such materials, and adversely affected the overall financial condition of Aerex’s current and prospective customers. Accordingly, in light of this new information from Aerex’s former major customer, and the on-going weak economic conditions that we believed would continue through 2022, we updated our projections of future cash flows for the manufacturing reporting unit and tested its goodwill for possible impairment as of June 30, 2021 using the discounted cash flow and guideline public company methods, with a weighting of 80% and 20% applied to these two methods, respectively. Based upon this testing, we determined that the carrying value of our manufacturing reporting unit exceeded its fair value by $2.9 million, and we recorded an impairment loss to reduce our manufacturing segment’s goodwill by this amount for the three months ended June 30, 2021.

Long-lived Assets

We review the carrying amounts of our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or a significant adverse change that would indicate that the carrying amount of an asset or group of assets is not recoverable. For long-lived assets to be held and used, we recognize an impairment loss only if

Table of Contents

its carrying amount is not recoverable through its undiscounted cash flows and measure the impairment loss based on the difference between the carrying amount and fair value.

Construction and Manufacturing Contract Revenue Recognition

We design, construct, and sell desalination infrastructure through DesalCo, which serves customers in the Cayman Islands, The Bahamas, and the British Virgin Islands. We design, construct, and sell wastewater, water reuse, and water production infrastructure in the United States through PERC and Kalaeloa Desalco. Aerex is a custom and specialty manufacturer in the United States of water-related systems and products applicable to commercial, municipal and industrial water production and treatment.

We recognize revenue for our construction and our specialized/custom manufacturing contracts (and some of our design contracts) over time under the input method using costs incurred (which represents work performed) to date relative to the total estimated costs at completion to measure progress toward satisfying a contract’s performance obligations, as such measure best reflects the transfer of control of the promised good to the customer. Contract costs include labor, materials, subcontractor costs and other expenses. We follow this method since we can make reasonably dependable estimates of the revenue and costs applicable to the various stages of a contract. Under this input method, we record revenue and recognize profit or loss as work on the contract progresses. We estimate total costs to be incurred and profit to be earned on each long-term, fixed price contract prior to commencement of work on the contract and update these estimates as work on the contract progresses. The cumulative amount of revenue recorded on a contract at a specified point in time is that percentage of total estimated revenue that incurred costs to date comprised of estimated total contract costs. Due to the extended time it may take to complete many of our contracts and the scope and nature of the work required to be performed on those contracts, the estimations of total revenue and costs at completion are complicated and subject to many variables and, accordingly, are subject to changes. When adjustments in estimated total contract revenue or estimated total contract costs are required, any changes from prior estimates are recognized in the current period for the inception-to-date effect of such changes. We recognize the full amount of any estimated loss on a contract at the time the estimates indicate such a loss.

The cost estimates we prepare in connection with our construction and manufacturing contracts are subject to inherent uncertainties. Because we base our contract prices on our estimation of future construction and manufacturing costs, the profitability of our construction and manufacturing contracts is highly dependent on our ability to estimate these costs accurately, as almost all of our construction and manufacturing contracts are fixed-price contracts. The cost of materials, labor and subcontractors could increase significantly after we sign a construction or manufacturing contract, which could cause the gross profit for a contract to decline from our previous estimates, adversely affecting our recognition of revenue and gross profit for the contract. Construction or manufacturing contract costs that significantly exceed our initial estimates could have a material adverse impact on our consolidated financial condition, results of operations, and cash flows.

Results of Operations

The following discussion and analysis of our results of operations should be read in conjunction with our audited consolidated financial statements and accompanying notes included under Part II, ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA, of this Annual Report.

Year Ended December 31, 2025 Compared to Year Ended December 31, 2024

Discontinued Operations – Mexico Project Development

In 2010, we began the pursuit, through our Netherlands subsidiary, Consolidated Water Cooperatief, U.A. (“CW-Cooperatief”), and our Mexico subsidiary, N.S.C. Agua, S.A. de C.V. (“NSC”), of a project (the “Project”) that encompassed the construction, operation and minority ownership of a 100 million gallons per day seawater reverse osmosis desalination plant to be located in northern Baja California, Mexico and accompanying pipeline to deliver water to the Mexican potable water system.

Through a series of transactions that began in 2012, NSC purchased 20.1 hectares of land for approximately $21.1 million on which the proposed Project’s plant was to be constructed.

Table of Contents

In November 2015, the State of Baja California (the “State”) officially commenced a public tender for the Project, and in June 2016 a consortium comprised of NSC and two other parties was selected by the State as the winner of the tender process for the Project. NSC subsequently formed AdR to pursue the completion of the Project.

On August 22, 2016, the Public Private Partnership Agreement for the Project (the “APP Contract”) was executed between AdR, the State Water Commission of Baja California (“CEA”), and the Government of Baja California as represented by the Secretary of Planning and Finance and the Public Utilities Commission of Tijuana (“CESPT”). The APP Contract required AdR to design, construct, finance and operate a seawater reverse osmosis desalination plant (and accompanying aqueduct) with a capacity of up to 100 million gallons per day in two phases: the first with a capacity of 50 million gallons per day and an aqueduct to the Mexican potable water system in Tijuana, Baja California and the second phase with a capacity of 50 million gallons per day. The first phase was to be operational within 36 months of commencing construction and the second phase was to be operational by January 2025. The APP Contract further required AdR to operate and maintain the plant and aqueduct for a period of 37 years starting from the commencement of operation of the first phase. At the end of the operating period, ownership of the plant and aqueduct would have been transferred to CEA.

On June 29, 2020, AdR received a letter (the “Letter”) from CEA and CESPT terminating the APP Contract. The Letter requested that AdR provide an inventory of the assets that comprised the “Project Works” (as defined in the APP Contract) for the purpose of acknowledging and paying the non-recoverable expenses made by AdR in connection with the Project, with such reimbursement to be calculated in accordance with the terms of the APP Contract. On August 28, 2020, AdR submitted their list of non-recoverable expenses, including those of NSC, to CEA and CESPT which amounted to 51,144,525 United States dollars and an additional 137,333,114 Mexican pesos.

CW-Cooperatief, as a Netherlands company, had certain rights relating to its investments in NSC and AdR under the Agreement on Promotion, Encouragement and Reciprocal Protection of Investments between the Kingdom of the Netherlands and the United Mexican States entered into force as of October 1, 1999 (the “Treaty”). On April 16, 2021, CW-Cooperatief submitted a letter to the President of Mexico and other Mexican federal government officials alleging that the State’s termination of the APP Contract constituted a breach by Mexico of its international obligations under the Treaty, entitling CW-Cooperatief to full reparation, including monetary damages. This letter invited Mexico to seek a resolution of this investment dispute through consultation and negotiation but stated that if the dispute cannot be resolved in this manner, CW-Cooperatief would refer the dispute to the International Centre for the Settlement of International Disputes for arbitration, as provided for in the Treaty.

In February 2022, CW-Cooperatief, filed a Request for Arbitration with the International Centre for Settlement of International Disputes (“ICSID”) requesting that the United Mexican States pay CW-Cooperatief damages in excess of US$51 million plus MXN$137 million (with the exact amount to be quantified in the proceedings), plus fees, costs and pre- and post-award interest.

In May 2024, we, through CW-Cooperatief, NSC, and AdR, entered into a settlement agreement (the “Settlement Agreement”) with the State and Banco Nacional de Obras y Servicios Públicos, S.N.C., as trustee under the trust agreement for the trust named Fondo Nacional de Infraestructura (the “Trust”). Under the Settlement Agreement, CW-Cooperatief requested that ICSID discontinue the arbitration and on May 31, 2024, ICSID issued an order discontinuing the arbitration. Pursuant to the Settlement Agreement, the Trust purchased the 20.1 hectares of land on which the Project’s plant was to be constructed, including related rights of way (the “Land”), on an “as-is” basis, from NSC for MXN$596,144,000. The sale of the Land to the Trust was closed on June 14, 2024 at which time the MXN$596,144,000 was paid to us and converted at the prevailing exchange rate on that date into US$31,959,685.

In connection with the Settlement Agreement on June 14, 2024, the State also paid NSC MXN$20,000,000 to purchase certain documentation owned by NSC relating to the Project.

As a result of the Settlement Agreement: (i) the parties have been released from all obligations owed to each other in connection with the APP Contract and the arbitration; and (ii) no party to the Settlement Agreement may institute any legal proceedings against another party thereto with respect to the matters which have been addressed by the Settlement Agreement.

Table of Contents

AdR was officially terminated/dissolved in the first quarter of 2026. We are presently in the process of legally terminating/dissolving CW-Cooperatief and NSC and expect to complete this process by mid-2026.

Our net income (loss) from discontinued operations for 2025 and 2024 was ($290,635) and $10,355,184, respectively.

Consolidated Results

Including discontinued operations, net income attributable to Consolidated Water Co. Ltd. stockholders for 2025 was $18,336,673 ($1.14 per share on a fully diluted basis), as compared to $28,237,554 ($1.77 per share on a fully diluted basis) for 2024.

The following discussion and analysis of our consolidated results of operations and results of operations by segment for the year ended December 31, 2025 as compared to the year ended December 31, 2024 relates only to our continuing operations.

Net income from continuing operations attributable to Consolidated Water Co. Ltd. stockholders for 2025 was $18,627,308 ($1.16 per share on a fully diluted basis), as compared to $17,882,370 ($1.12 per share on a fully diluted basis) for 2024.

Revenue for 2025 decreased to $132,073,368 from $133,966,633 in 2024, due to decreases in the revenue from our services and bulk segments. Gross profit for 2025 was $48,378,810 (37% of total revenue) as compared to $45,624,448 (34% of total revenue) for 2024. For further discussion of revenue and gross profit see the “Results by Segment” discussion and analysis that follows.

General and administrative expenses (“G&A expenses”) on a consolidated basis increased to $30,116,328 for 2025 as compared to $27,537,436 for 2024. The principal factors for the increase in G&A expenses for 2025 were incremental (i) employee costs of almost $1.3 million arising from new hires, pay increases and increased benefits costs; (ii) legal and professional fees of approximately $503,000; and (iii) information technology expenses of approximately $334,000 incurred for the implementation of a new retail billing system.

Other income, net, increased to $3,024,944 in 2025, as compared to $2,393,676 in 2024 primarily due to $575,850 of additional interest income earned on higher balances of interest earning assets.

Results by Segment

Retail Segment:

The retail segment generated $15,300,161 of income from operations for 2025 as compared to $14,280,948 for 2024.

Revenue generated by our retail water operations increased to $33,587,952 in 2025 from $31,741,343 in 2024 due to an 8.3% increase in the volume of water sold. The amount of water Cayman Water sold in 2025 (1.09 billion gallons) was the highest in our history. We believe this volume increase in water sold resulted from significantly lower rainfall on Grand Cayman (which was 40% below the 30-year average and 45% lower than 2024) and a 6.6% increase in the number of customer accounts in our license area from December 31, 2024 to December 31, 2025.

As a result of the revenue increase, retail segment gross profit increased in both total dollars and as a percentage of revenue to $18,994,259 (57% of retail revenue) for 2025 as compared to $17,542,255 (55% of retail revenue) for 2024.

Retail G&A expenses increased to $3,734,676 for 2025 as compared to $3,263,593 for 2024 due to incremental technology expenses of approximately $334,000 resulting from the ongoing implementation of a new billing system.

Bulk Segment:

The bulk segment contributed $9,396,351 and $8,748,052 to our income from operations for 2025 and 2024, respectively.

Table of Contents

Bulk segment revenue was $33,481,307 and $33,673,387 for 2025 and 2024, respectively. The decrease in bulk revenue from 2024 to 2025 reflects a decrease in the price of energy for CW-Bahamas, which decreased the energy pass-through component of CW-Bahamas’ rates.

Gross profit for our bulk segment was $11,011,110 (33% of bulk revenue) and $10,313,027 (31% of bulk revenue) for 2025 and 2024, respectively. Gross profit as a percentage of revenue increased slightly in 2025 as compared to 2024 due to improved plant efficiency and reductions in various operating expenses.

Bulk segment G&A expenses remained relatively consistent at $1,614,759 for 2025 as compared to $1,564,975 for 2024.

Services Segment:

The services segment contributed $4,028,856 and $6,392,259 to our income from operations for 2025 and 2024, respectively.

Services segment revenue decreased to $46,312,325 for 2025 compared to $50,956,489 for 2024. Construction revenue declined to $13,470,641 in 2025 as compared to $18,602,919 in 2024, as we recognized $8.2 million of additional revenue from PERC’s contract with Liberty Utilities and $1.3 million in revenue from the Red Gate contract in Grand Cayman in 2024. These contracts were substantially completed in mid-2024. Construction revenue recognized on the Hawaii contract also declined by $2.9 million in 2025 due to the completion of the pilot plant testing phase of the project. These decreases in construction revenue were partially offset by construction revenue generated under new contracts. Revenue generated under operations and maintenance contracts increased to $32,075,046 in 2025 from $29,307,405 in 2024 due to incremental revenue generated by both PERC and REC. Design and consulting revenue decreased to approximately $767,000 in 2025 from approximately $3.0 million in 2024 due to the completion in the fourth quarter of 2024 of a contract for a major plant commissioning and startup project.

The gross profit for the services segment decreased to $11,862,481 (26% of services revenue) in 2025 as compared to $12,444,954 (24% of services revenue) for 2024 due to the decrease in construction and design and consulting revenue.

We have been informed by one of our significant operations and maintenance customers that it will not extend its existing contract with PERC beyond its expiration date in March 2026. We recognized approximately $5.5 million and $1.8 million in revenue and gross profit, respectively, under this contract in 2025.

G&A expenses for the services segment increased to $7,885,756 for 2025 as compared to $6,055,409 for 2024 primarily due to incremental employee costs of $1,181,678 attributable to new hires and salary increases and an increase of $301,173 in the provision for credit losses for the services segment.

In June 2023, we (through our subsidiary Kalaeloa Desalco) executed a contract with the Honolulu Board of Water Supply (“BWS”) to construct and operate a 1.7 million gallons per day seawater reverse osmosis desalination plant in Oahu, Hawaii, and since that time we have been engaged in the design and development phase for construction of the plant. We have achieved major project milestones under this phase of the project, (i) including successful pilot plant testing, (ii) receipt of confirmation from BWS that we are able to produce water that is a “reasonable match” to the quality of BWS’s current water supply and that we are able to produce water that causes “no detrimental impact” to the BWS water system or their customers’ assets, and (iii) completion of the plant design.

We are required to obtain federal, state, regional and local permits, licenses and other government approvals as a condition to commencing and completing construction and initiating operations. The permitting process for a project of this scale and complexity is inherently iterative and subject to review by multiple regulatory authorities, public comment procedures and, in certain instances, interagency coordination. During the year ended December 31, 2025, and continuing through the time of the filing of this Annual Report on Form 10-K, we and BWS have experienced delays in obtaining certain required permits and related governmental approvals. These delays have resulted in a corresponding deferral of certain project milestones and a delay in the commencement of plant construction.

Table of Contents

Pursuant to the terms of the contract, we are entitled to extensions of time for performance should delays arise from the failure to obtain required permits or other governmental approvals, provided that we have satisfied certain contractually specified conditions, including the exercise of all reasonable efforts to obtain such permits or other governmental approvals. We believe that we have complied in all material respects with the contractual prerequisites necessary to obtain relief in respect of such delays. Based on ongoing discussions with representatives of the BWS and its advisors, we currently expect that appropriate extensions of time will be granted to Kalaeloa Desalco to reflect the impact of the permitting delays on the project schedule. However, until formal change orders, amendments or written confirmations are executed, there can be no assurance as to the timing, scope or terms of any such extensions, or if such extensions will be granted at all.

The ultimate duration and economic burden of the permitting process remain subject to factors outside of our control, including the workload and resource constraints of applicable regulatory authorities, the timing and outcome of required public processes, the resolution of technical comments or requests for supplemental information and the potential for administrative or judicial challenges. To the extent that Kalaeloa Desalco does not receive the anticipated extensions of time, or if the extensions granted are insufficient to accommodate the full period of delay, Kalaeloa Desalco could be exposed to contractual remedies available to the BWS, which may include the assessment of liquidated damages, the withholding of milestone payments, or termination of the contract.

At the time of the filing of this Annual Report on Form 10-K, Kalaeloa Desalco is continuing to advance the permitting process, respond to regulatory inquiries and coordinate with the BWS to mitigate schedule impacts. Kalaeloa Desalco also is evaluating potential adjustments to sequencing and procurement activities designed to reduce the effect of the delays on the overall project economics. Although we do not currently expect the permitting delays to result in a material adverse effect on our consolidated financial position, the deferral of construction activities has shifted anticipated revenue recognition and associated cash flows related to the Hawaii desalination plant project into future periods. We will continue to assess the impact of these developments on our estimates of total project costs, timing of performance obligations and variable consideration, and will update our disclosures as appropriate in future periodic or current reports.

Manufacturing Segment:

The manufacturing segment contributed $4,413,201 and $2,867,405 to our income from operations in 2025 and 2024, respectively.

Manufacturing revenue increased to $18,691,784 for 2025 as compared to $17,595,414 for 2024.

Manufacturing gross profit was $6,510,960 (35% of manufacturing revenue) for 2025 as compared to a gross profit of $5,324,212 (30% of manufacturing revenue) for 2024. The increase in manufacturing gross profit in dollars and as a percentage of revenue results from increased production activity, production efficiencies and a higher margin product mix.

G&A expenses for the manufacturing segment decreased to $2,102,759 for 2025 as compared to $2,456,807 for 2024 due to a decrease in the provision for credit losses for the manufacturing segment of approximately $359,000 in 2025.

Corporate:

Corporate G&A expenses increased to $14,778,378 for 2025 as compared to $14,196,652 for 2024 as a result of approximately $291,000 in incremental professional fees and smaller increases in various other expense accounts.

Discontinued Operations – Mexico Project Development

As discussed previously, on June 30, 2020 the State of Baja California cancelled its APP Contract with AdR for the Project. As a result of the cancellation of the Project, we discontinued all development activities associated with the Project, commenced marketing efforts to sell the land NSC purchased for the Project, and initiated international arbitration against the Government of Mexico to recover the costs we had incurred for the Project. In May 2024, we executed a Settlement Agreement with the State pursuant to which we discontinued the arbitration in exchange for the purchase by the State (i) of the land for the Project for MXN$596,144,000; and (ii) certain documentation for the Project for MXN$20,000,000. We received the proceeds from the sale of the land and documentation in June 2024.

We are presently in the process of legally terminating/dissolving CW-Cooperatief, NSC and AdR and will continue to incur expenses for these subsidiaries until such processes are completed.

Our net income (loss) from discontinued operations for 2024 and 2023 was $10,355,184 and ($1,086,744), respectively. The net income reported from discontinued operations for 2024 reflects the gain generated from the sale of the Project land and documentation under the Settlement Agreement.

Consolidated Results

Including discontinued operations, net income attributable to Consolidated Water Co. Ltd. stockholders for 2024 was $28,237,554 ($1.77 per share on a fully diluted basis), as compared to $29,585,391 ($1.86 per share on a fully diluted basis) for 2023.

The following discussion and analysis of our consolidated results of operations and results of operations by segment for the year ended December 31, 2024 as compared to the year ended December 31, 2023 relates only to our continuing operations.

Net income from continuing operations attributable to Consolidated Water Co. Ltd. stockholders for 2024 was $17,882,370 ($1.12 per share on a fully diluted basis), as compared to $30,672,135 ($1.93 per share on a fully diluted basis) for 2023.

Revenue for 2024 decreased to $133,966,633 from $180,211,233 in 2023, due to a significant decrease in revenue from our services segment. Gross profit for 2024 was $45,624,448 (34% of total revenue) as compared to $61,927,105 (34% of total revenue) for 2023. For further discussion of revenue and gross profit see the “Results by Segment” discussion and analysis that follows.

General and administrative expenses (“G&A expenses”) on a consolidated basis increased to $27,537,436 for 2024 as compared to $24,752,366 for 2023. The principal factors for the increase in G&A expenses for 2024 relates to additional G&A expenses of approximately $1,321,000 attributable to REC, which was acquired in the fourth quarter of 2023, and incremental audit, legal and audit related and other professional fees of approximately $1,357,000.

Other income, net, increased to $2,393,676 in 2024, as compared to $828,313 in 2023 primarily due to $1,397,782 of additional interest income resulting from additional interest earned on higher balances of interest earning assets and higher late payment charges on delinquent accounts receivable balances due from the WSC.

Results by Segment

Retail Segment:

The retail segment generated $14,280,948 of income from operations for 2024 as compared to $13,266,942 for 2023.

Revenue generated by our retail water operations increased to $31,741,343 in 2024 from $30,158,051 in 2023 due to a 4.5% increase in the volume of water sold. We believe the increase in the volume of water sold in 2024 resulted in part

Table of Contents

from a 4.3% increase in the number of customer accounts in our license area from December 31, 2023 to December 31, 2024.

Retail segment gross profit increased to $17,542,255 (55% of retail revenue) for 2024 as compared to $16,266,822 (54% of retail revenue) for 2023 due to the revenue increase. Retail segment gross profit as a percentage of revenue increased slightly in 2024 as compared to 2023 due to the overall increase in water volume sold.

Retail G&A expenses remained relatively consistent at $3,263,593 for 2024 as compared to $2,978,164 for 2023.

Bulk Segment:

The bulk segment contributed $8,748,052 and $8,742,382 to our income from operations for 2024 and 2023, respectively.

Bulk segment revenue was $33,673,387 and $34,595,058 for 2024 and 2023, respectively. The decrease in bulk revenue from 2023 to 2024 reflects a decrease in the price of energy for CW-Bahamas, which decreased the energy pass-through component of CW-Bahamas’ rates.

Gross profit for our bulk segment was $10,313,027 (31% of bulk revenue) and $10,466,926 (30% of bulk revenue) for 2024 and 2023, respectively. Gross profit as a percentage of revenue increased slightly in 2024 as compared to 2023 due to higher revenue, efficiency improvements at OC-Cayman, and decreases in electricity and fuel costs and depreciation expense that more than offset increased maintenance and insurance expenses.

Bulk segment G&A expenses remained relatively consistent at $1,564,975 for 2024 as compared to $1,737,264 for 2023.

Services Segment:

The services segment contributed $6,392,259 and $26,897,080 to our income from operations for 2024 and 2023, respectively.

Services segment revenue decreased to $50,956,489 for 2024 compared to $97,966,650 for 2023. Construction revenue was $18,602,919 in 2024 as compared to $77,306,704 in 2023. We recognized approximately $8.5 million and $64 million in construction revenue for the Liberty Utilities contract for the construction of a water treatment plant in Goodyear, Arizona in 2024 and 2023, respectively. This contract was completed in mid-2024. Revenue generated under operations and maintenance contracts increased to $29,307,405 in 2024 from $19,368,365 in 2023. Revenue from REC, which was acquired in October 2023, constituted $6,069,342 of this operations and maintenance contracts revenue increase and the remainder of the increase related to new PERC contracts. Design and consulting revenue increased to approximately $3.0 million in 2024 from approximately $1.3 million in 2023.

The gross profit for the services segment decreased to $12,444,954 (24% of services revenue) in 2024 as compared to $31,168,888 (32% of services revenue) for 2023 due to the decrease in construction revenue.

G&A expenses for the services segment increased to $6,055,409 for 2024 as compared to $4,271,808 for 2023 primarily due to incremental G&A expenses of REC (which was acquired in the fourth quarter of 2023) of approximately $1,321,000.

Manufacturing Segment:

The manufacturing segment contributed $2,867,405 and $2,188,418 to our income from operations in 2024 and 2023, respectively.

Manufacturing revenue remained relatively consistent at $17,595,414 and $17,491,474 for 2024 and 2023, respectively.

Manufacturing gross profit was $5,324,212 (30% of manufacturing revenue) for 2024 as compared to a gross profit of $4,024,469 (23% of manufacturing revenue) for 2023. The increase in manufacturing gross profit in dollars and as a percentage of revenue results from a higher margin product mix.

Table of Contents

G&A expenses for the manufacturing segment increased to $2,456,807 for 2024 as compared to $1,838,284 for 2023 principally due to an increase in the provision for credit losses for the manufacturing segment of approximately $336,000 in 2024.

Corporate:

Corporate G&A expenses increased slightly to $14,196,652 for 2024 as compared to $13,926,846 for 2023. This increase reflects almost $1.2 million incremental audit, consulting and legal fees arising primarily from the Company’s change in S.E.C. filing status from a small reporting company to an accelerated filer.

FINANCIAL CONDITION

The significant changes in the components of our consolidated balance sheet as of December 31, 2025 as compared to December 31, 2024 (other than the change in our cash and cash equivalents, which is discussed later in “LIQUIDITY AND CAPITAL RESOURCES”) and the reasons for these changes are discussed in the following paragraphs.

Accounts receivable decreased by approximately $6.8 million, primarily due to a $7.6 million decrease in CW-Bahamas’ accounts receivable.

Current inventory decreased by $5.2 million, primarily due to a decrease of $5.1 million in Aerex’s inventory resulting from the consumption of materials used in product production.

Contract assets decreased by approximately $1.2 million, primarily due to a $1.1 million decrease in Aerex’s contract assets.

Property, plant and equipment, net, increased by approximately $2.7 million, primarily due to the completion of the expansion of Aerex’s manufacturing facility, transfers from construction in progress relating to the new West Bay plant, and the purchase of specialized equipment for the services segment, partially offset by the scheduled depreciation of fixed assets.

Construction in progress increased by approximately $1.6 million, primarily due to $3.2 million spent on the CW-Bahamas Cat Island plant construction, partially offset by a decrease of $1.7 million resulting from the additional capitalization of completed and in-use components of the West Bay plant expansion in Grand Cayman.

Contract liabilities increased by approximately $2.4 million, primarily due to the Kalaeloa Desalco construction project.

LIQUIDITY AND CAPITAL RESOURCES

Certain transfers from our bank accounts in The Bahamas to our bank accounts in other countries require the approval of the Central Bank of The Bahamas.

The Cayman Islands does not have a tax treaty with the United States. Consequently, should we be required (or elect) to transfer any profits generated by our U.S. subsidiaries to our parent company in the Cayman Islands, we would be required to pay a withholding tax of 30% on the amount of any such funds transferred.

Liquidity Position

Our projected liquidity requirements for 2026 include capital expenditures for our existing operations of approximately $11.1 million, which includes approximately $1.0 million to be incurred during the first half of 2026 for a project in the Bahamas. We paid approximately $2.3 million in dividends in January 2026. Our liquidity requirements may also include future quarterly dividends, if such dividends are declared by our Board.

As of December 31, 2025, we had cash and cash equivalents of $123.8 million and working capital of $141.9 million.

Table of Contents

With the exception of the liquidity matter relating to CW-Bahamas that is discussed in the paragraphs that follow, we are not presently aware of anything that would lead us to believe that we will not have sufficient liquidity to meet our needs.

CW-Bahamas Liquidity

If CW-Bahamas is unable to collect a sufficient portion of its delinquent accounts receivable, one or more of the following events may occur: (i) CW-Bahamas may not have sufficient liquidity to meet its obligations; (ii) we may be required to cease the recognition of revenue on CW-Bahamas’ water supply agreements with the WSC; and (iii) we may be required to provide a material allowance for credit losses for CW-Bahamas’ accounts receivable. Any of these events could have a material adverse impact on our consolidated financial condition, results of operations, and cash flows.

Discussion of Cash Flows for the Year Ended December 31, 2025

Our cash and cash equivalents increased to $123,788,390 as of December 31, 2025 from $99,350,121 as of December 31, 2024.

Cash Flows from Operating Activities

Net cash provided by our operating activities was $41,713,571. This net cash provided reflects net income generated for the year ended December 31, 2025 of $18,929,852 as adjusted for (i) various items included in the determination of net income that do not affect cash flows during the year; and (ii) changes in the other components of working capital. The more significant of such items and changes in working capital components includesdepreciation and amortization of $6,903,438, a decrease in accounts receivable of $6,519,621 attributable principally to CW-Bahamas, a decrease in inventory of $4,240,636 and an increase in contract liabilities of $2,401,980.

Cash Flows from Investing Activities

Net cash used in our investing activities was $8,439,222 primarily for additions to property, plant and equipment and construction in progress.

Cash Flows from Financing Activities

Net cash used in our financing activities was $8,950,163, almost all of which related to the payment of dividends.

Material Commitments, Expenditures and Contingencies

Cayman Water Retail License

We sell water through our retail operations under a license issued in July 1990 by the Cayman Islands government (the “1990 license”) that granted Cayman Water the exclusive right to provide potable water to customers within its licensed service area. Pursuant to the 1990 license, Cayman Water has the exclusive right to produce potable water and distribute it by pipeline to its licensed service area, which consists of two of the three most populated areas of Grand Cayman Island: Seven Mile Beach and West Bay. In 2025, 2024, and 2023 we generated approximately 26%, 24% and 17%, respectively, of our consolidated revenue and 39%, 38% and 26%, respectively, of our consolidated gross profit from the retail water operations conducted under the 1990 license.

The 1990 license was originally scheduled to expire in July 2010 but was extended several times by the Cayman Islands government to provide the parties with additional time to negotiate the terms of a new license agreement. The most recent express extension of the license expired on January 31, 2018. From that date until February 18, 2025, we continued to operate under the terms of the 1990 license, treating such terms as operative notwithstanding the expiration of the express extension. We continued to pay a royalty of 7.5% of the revenue we collect as required under the 1990 license.

In October 2016, the Government of the Cayman Islands passed legislation which created a new utilities regulation and competition office (“OfReg”) and, in April 2017, passed supplemental legislation which transferred responsibility for economic regulation of the water utility sector and the negotiations with us for a new retail license to OfReg.

We have been informed during our retail license negotiations, both by OfReg and its predecessor in these negotiations, that they seek to restructure the terms of the license in a manner that could significantly reduce the operating income and cash flows we have historically generated from our retail license. We are presently unable to determine what impact the resolution of our retail license negotiations will have on our consolidated financial condition, results of operations, or cash flows but such resolution could result in a material reduction (or the loss) of the operating income and cash flows we have historically generated from our retail operations and could require us to record impairment losses to reduce the carrying values of our retail segment assets. Such impairment losses could have a material adverse impact on our consolidated financial condition and results of operations.

CW-Bahamas Supply Guarantees

Our contracts to supply water to the WSC from our Blue Hills and Windsor plants require us to guarantee delivery of a minimum quantity of water per week. If the WSC requires the water and we do not meet this minimum, we are required to pay the WSC for the difference between the minimum and actual gallons delivered at a per gallon rate equal to the price per gallon that the WSC is currently paying us under the contract. The Blue Hills contract expires in 2032 and requires us to deliver 63.0 million gallons of water each week. The Windsor contract expires in 2033 and requires us to deliver 16.8 million gallons of water each week. We have been in compliance with the performance guarantees under these contracts for all periods since the inception of the contracts.

Adoption of New Accounting Standards

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The Company adopted the standard as of December 31, 2025, including a recast of 2024 and 2023 information, by including additional required disclosures within the Notes to the Consolidated Financial Statements. See Note 11—Income Taxes for further details. There was no impact on our consolidated financial position, results of operations or cash flows.

Effect of Newly Issued but not yet Effective Accounting Standards

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires public companies to disclose, in the notes to financial statements, specific information about certain costs and expenses at each interim and annual reporting period. The amended ASU is effective on a prospective basis for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. We are currently evaluating the impact of this guidance.

Dividends

We have paid dividends to owners of our common stock and redeemable preferred stock since we began declaring dividends in 1985. Our payment of any future cash dividends will depend upon our earnings, financial condition, cash flows, capital requirements and other factors our Board of Directors deems relevant in determining the amount and timing of such dividends.

Dividend Reinvestment and Common Stock Purchase Plan

This plan is available to our shareholders, who may reinvest all or a portion of their common stock dividends into shares of common stock at prevailing market prices and may also invest optional cash payments to purchase additional shares at prevailing market prices as part of this plan.

Impact of Inflation

Under the terms of our bulk water sales agreements in The Cayman Islands, The Bahamas and the British Virgin Islands, our water rates are automatically adjusted for inflation on an annual basis. Therefore, the impact of inflation on our gross profit from these revenue sources, measured in consistent dollars, historically has not been material. However, while we have received annual inflation adjustments for the rates we charge under our bulk water agreements, we have not applied to increase the water rates for Cayman Water since January 2018 (despite the inflation that has occurred since that date) due to the delayed resolution of our negotiations with OfReg for a new retail license. While we believe that we are entitled to apply to OfReg for future rate adjustments under the terms of the February 18, 2025 concession agreement with the Cayman Islands government, the denial by OfReg of such application or approval of an increase that is less than the increase in our costs could adversely affect the profitability of our retail segment. Furthermore, our manufacturing segment has in the past been adversely impacted by significant increases in raw material costs and our manufacturing and services segments could suffer similar adverse impacts in the future.

Table of Contents

While our operations and maintenance contracts are generally adjusted for inflation on an annual basis, such adjustment for many of these contracts is capped at 3% annually.

Kalaeloa Desalco has signed a contract with the Honolulu Board of Water Supply pursuant to which it presently expects to construct and operate a 1.7 million gallons per day seawater reverse osmosis desalination plant in Oahu, Hawaii. Approximately 80% of the $147 million price for the construction of this plant is subject to adjustment based upon changes in inflation indices from September 29, 2022 (the date that was 120 days after the original proposal was submitted) until the date that the notice to proceed with construction is issued by the client.

Increases in fuel and energy costs and other items could create additional credit risks for us, as our customers’ ability to pay our invoices could be adversely affected by such increases.
