Management Commentary “In Q3, our diversified water business model, which includes regulated utility operations, design and construction services, O&M services manufacturing, continued to perform well,” commented Consolidated Water CEO, Rick McTaggart. “As a result, our consolidated revenue by 5% and our fully diluted earnings per share from continuing operations increased 10% compared to the same year-ago period. “The continued strength of the economy and lower rainfall on Grand Cayman resulted in our retail segment revenue up about 2% compa same year ago quarter, on about a 6% increase in water volume sold. While bulk segment revenue decreased slightly this past quarter d fuel pass-through charges, bulk profitability increased in dollars and gross profit percentage due to lower costs of revenue reflecting our u focus on operational excellence. “Our services segment revenue increased by $1.6 million or 13% due to a $2.1 million increase in construction revenue from two projects lesser extent from a $223,000 increase in recurring revenue from O&M contracts. These revenue increases were partially offset by a dec consulting revenue of $720,000 due to the completion in the fourth quarter of 2024 of a major plant commissioning and startup project. “Earlier this month, we announced that we had secured a contract valued at $11.7 million to construct a wastewater recycling plant for a S Francisco Bay Area golf club. This innovative project, which will convert untreated wastewater to irrigation water, is expected to save 36 t gallons per year of potable water. We expect revenue from this project to be recognized primarily in 2026. “During the quarter, our manufacturing segment continued its improved performance. Manufacturing revenue grew by 7% and gross mar increased to 40%, which reflects the production this past quarter of primarily higher margin products for nuclear power and municipal wat as well as our continued focus on maximizing production efficiency and capacity. The completion of our new 17,500-square-foot manufac facility expansion this past quarter is expected to further enhance efficiency and throughput. As previously reported, we hold NQA-1 certi from two major nuclear industry companies and see renewed interest in U.S. nuclear power solutions. These specialized manufacturing qualifications position us for continued growth. “Design of the 1.7 million gallon per day seawater desalination plant for the Honolulu Board of Water Supply in Kalaeloa, Hawaii is now 1 complete and we are focused on obtaining the remaining permits needed to allow our client to issue a notice to proceed with construction project. We continue to anticipate that construction of the project will commence early next year. We see this major construction phase su adding to our revenue and earnings growth in 2026 and 2027. “In October, we welcomed Kim Adamson, Maria Elena Giner, and Gerónimo Gutiérrez Fernández to our board of directors. Their combined in water utility operations and governance, large-scale infrastructure delivery and capital program management, and international infrastr finance and policy greatly strengthens our corporate governance and overall expertise related to our business. We expect their experienc accelerate execution of our strategic priorities, enhance oversight of capital programs, and drive long-term shareholder value. “Looking ahead, our strong balance sheet and ample liquidity enable us to fund growth initiatives, and we believe our diversified business segments will continue to deliver improved results to shareholders.”
