Use of estimates: The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the 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. Significant items subject to estimates and assumptions include the carrying value of property, plant and equipment, intangible assets, goodwill and revenue recognition on construction and manufacturing contracts. Actual results could differ significantly from such estimates.

Foreign currency: The Company’s reporting currency is the United States dollar (“US$”). The functional currency of the Company and its foreign operating subsidiaries (other than NSC, AdR, and CW-Cooperatief) is the currency for each respective country. The functional currency for NSC, AdR, and CW-Cooperatief is the US$. NSC and AdR conduct business in US$ and Mexican pesos and CW-Cooperatief conducts business in US$ and euros. The exchange rates for the Cayman Islands dollar and the Bahamian dollar are fixed to the US$. The exchange rates for conversion of Mexican pesos and euros into US$ vary based upon market conditions.

Net foreign currency gains arising from transactions and re-measurements were $39,259, $74,993 and $84,678 for the years ended December 31, 2025, 2024, and 2023, respectively, and are included in “Other income (expense) - Other” in the accompanying consolidated statements of income.

Accounts receivable

Accounts receivable: Accounts receivable are recorded at invoiced amounts based on meter readings, contractual amounts, fixed fees plus reimbursables or time and materials per contractual agreements. Trade accounts receivable also represent our unconditional right, subject only to the passage of time, to receive consideration arising from our performance under contracts with customers. Trade accounts receivable include amounts billed and billable on construction contracts, service and maintenance contracts and contracts for the sale of goods. Billed contract receivables have been invoiced to customers based on contracted amounts.

Inventory

Inventory: Inventory primarily consists of consumables stock and spare parts stock that are valued at cost, less an allowance for obsolescence, with cost determined on the first-in, first-out basis. Inventory also includes (i) raw materials purchased for specific manufacturing contracts that are valued at cost on the first-in, first-out basis; and (ii) potable water held in the Company’s reservoirs that is valued at the lower of the average cost of producing water during the year or its net realizable value.

Property, plant and equipment, net

Property, plant and equipment, net: Property, plant and equipment is stated at cost less accumulated depreciation. Depreciation is calculated using a straight-line method with an allowance for estimated residual values. Rates are determined based on the estimated useful lives of the assets as follows:


Buildings		5 to 40 years
Plant and equipment		4 to 40 years
Distribution system		3 to 40 years
Office furniture, fixtures and equipment		3 to 10 years
Vehicles		3 to 10 years
Leasehold improvements		Shorter of 5 years or lease term
Lab equipment		5 to 10 years

Assets under construction are recorded as additions to property, plant and equipment upon completion of the projects. Depreciation commences in the month the asset is placed in service. Additions to construction in progress are comprised of the cost of the contracted services, direct labor and materials.

Interest costs directly attributable to the acquisition and construction of qualifying assets, which are assets that necessarily take a substantial amount of time to be ready for their intended use, are added to the cost of those assets until such time as the assets are substantially ready for use. No interest was capitalized during the years ended December 31, 2025 or 2024.

Goodwill and intangible assets

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. The Company evaluates the possible impairment of goodwill annually as part of its reporting process for the fourth quarter of each fiscal year. Management identifies the Company’s 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. The Company determines the fair value of each reporting unit and compares 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 the years ended December 31, 2025 and 2024, the Company elected to assess qualitative factors to determine whether it was necessary to perform the quantitative goodwill impairment testing that was conducted in prior years for its reporting units. The Company assessed the relevant events and circumstances to evaluate whether it is more likely than not that the fair values of such reporting units were 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, the Company determined that it is more likely than not that the fair values of its reporting units exceeded their carrying values as of December 31, 2025 and 2024.

Income taxes

Income taxes: The Company accounts for the income taxes arising from the operations of its United States subsidiaries under the asset and liability method. Deferred tax assets and liabilities, if any, are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided to the extent any deferred tax asset may not be realized.

The Company is not presently subject to income taxes in the other countries in which it operates.

Comparative amounts

Comparative amounts: Revenue of $965,487 for 2024 presented in the services segment as design and consulting revenue in the financial statements previously issued for 2024 has been reclassified to construction revenue in the services segment information for 2024 provided herein to conform to the current period’s presentation. Such reclassifications had no effect on consolidated or services segment revenue, gross profit, operating income or net income
