CALIFORNIA WATER SERVICE GROUP

Previous wording

Cal Water, New Mexico Water, Washington Water, and Hawaii Water are regulated public utilities, which provide water and water-related service to our customers. Additionally, Hawaii Water and Texas Water own in whole or in part other companies which are regulated public utilities. The rates that we charge our water customers are subject to the jurisdiction of the regulatory Commissions in the states in which we operate. These Commissions may set water and water-related rates for each operating district independently because the systems are not interconnected. The Commissions authorize us to charge rates that they consider sufficient to recover normal operating expenses, to provide funds for adding new or replacing water infrastructure, and to allow us the opportunity to earn what the Commissions consider to be a fair and reasonable return on invested capital.

Previous wording

We periodically file rate increase applications with the Commissions. The ensuing administrative and hearing process may be lengthy and costly. The decisions of the Commissions are beyond our control and we can provide no assurances that our rate increase requests will be granted by the Commissions. Even if approved, there is no guarantee that approval will be given in a timely manner or at a sufficient level to cover our expenses and provide a reasonable return on our investment. Our earnings have in the past been and may in the future be adversely affected when rate increase decisions are delayed or approved at a level that is lower than what we have requested. For example, the CPUC did not issue its decision on our 2021 GRC until March 2024, over a year later than expected, which caused uncertainty around and volatility in our financial and operating results until that time.

Even if approved, there is no guarantee that approval will be given in a timely manner or at a sufficient level to cover our expenses and provide a reasonable return on our investment. Our earnings have in the past been and may in the future be adversely affected when rate increase decisions are delayed or approved at a level that is lower than what we have requested. For example, the CPUC has not issued its final decision on our 2024 CA GRC, which has caused uncertainty around, and may cause volatility in, our financial and operating results for our Company.

Previous wording

Regulatory agencies may change their rules and policies for various reasons, including changes in the local political environment. Regulators are appointed by popular vote or are appointed by elected officials, and the election of a new administration or the appointment of new officials due to the results of elections may result in dramatic change to the long-established rules and policies of an agency. For example, in 2020 regulation regarding full decoupling WRAMs temporarily changed in California. Since 2008, the CPUC allowed full decoupling WRAMs. However, in 2020, the CPUC precluded companies from proposing full decoupling WRAMs in their next GRC filings. As a result, we were precluded from requesting a full decoupling WRAM from the time of the 2021 GRC application until the California Supreme Court’s decision on July 8, 2024 voiding the WRAM provisions in the August 27, 2020 CPUC decision. In addition, the recent change in U.S. federal administration has led and is expected to continue to lead to changes in the leadership of various U.S. federal regulatory agencies and changes or proposed or threatened changes to U.S. federal government policy that have led to, in some cases, legal challenges as well as uncertainty around the funding, functioning and policy priorities of U.S. federal regulatory agencies and the status of current and future regulations. U.S. federal government policy changes have included seeking to temporarily broadly halt federal funding, seeking to aggressively downsize the U.S. federal government’s workforce and instructing federal agencies to reprioritize or to cease operating or enforcing certain laws or regulations. We are unable to predict the extent to which the current U.S. federal administration may impose or seek to impose leadership or policy changes at the U.S. federal regulatory agencies responsible for regulating our business, including changes or proposed changes at the EPA or SEC, or changes or proposed changes to rules and policies impacting our operations. Any such changes could impose additional costs, require the attention of senior management or result in other changes to or limitations on our business.

U.S. federal government policy changes have included efforts to modify or restrict federal funding, restructure federal agency operations or workforce and instructing federal agencies to adjust, delay, or suspend the implementation or enforcement of certain laws or regulations or to cease operating. We are unable to predict the extent to which the current U.S. federal administration may continue to impose or seek to impose leadership or policy changes at the U.S. federal regulatory agencies responsible for regulating our business, including changes or proposed changes at the EPA or SEC, or changes or proposed changes to rules and policies impacting our operations. Any such changes may impose additional cost or result in other changes to or limitations on our business.

Previous wording

Finally, local jurisdictions may impose new ordinances, laws, fees, and regulations that could increase costs or limit our operations, which affect future operating results. Cities may impose or amend franchise requirements, impose conditions on underground construction or land use, impose various taxes and fees, or restrict our hours for construction, among other things. In the last decade, more cities have imposed excavation moratoria or paving rules, which has resulted in delays and required more costly construction than anticipated.

Current wording

Finally, state and local jurisdictions may impose new ordinances, laws, fees, and regulations that could increase costs or limit our operations, which affect future operating results. For example, as a result of the recent wildfires that devastated communities in southern California, the Governor of California signed Assembly Bill 367 into law that went into effect on January 1, 2026. The bill creates additional requirements for water utilities in Ventura County, or our Westlake district, related to fire protection. Cal Water is required to have access to sufficient backup energy to operate wells and water pumps that are critical for supplying water for fire suppression in the high or very high fire hazard severity zone beginning July 1, 2030. Cal Water is also required to prepare an emergency preparedness plan for responding to red flag warnings, extreme weather events, and major power outages. Cities may impose or amend franchise requirements, impose conditions on underground construction or land use, impose various taxes and fees, or restrict our hours for construction, among other things. More cities are imposing excavation moratoria or paving rules, which has resulted in delays and required more costly construction than anticipated.

Previous wording

Past events in the utility sector, including those in Flint, Michigan and those related to Pacific Gas and Electric Company in California, show that failure to meet one or more water quality, environmental, or safety standards can have severe effects on customer trust, reputation, regulatory treatment, or civil and criminal liability.

Current wording

Past events in the utility sector, including those relating to drinking water contamination in Flint, Michigan and those related to safety and wildfire-related compliance failures at Pacific Gas and Electric Company in California, show that failure to meet one or more water quality, environmental, or safety standards can have severe effects on customer trust, reputation, regulatory treatment, or civil and criminal liability.

Previous wording

We are subject to water quality standards set by federal, state, and local authorities that have the power to issue new regulations. Compliance with new regulations that are more stringent than current regulations could increase our operating costs and capital expenditures, including requirements for increased monitoring, additional treatment of surface water and groundwater supplies, fluoridation of all supplies, more stringent performance standards for treatment plants, additional procedures to further reduce levels of disinfection by-products, and more comprehensive measures to monitor, reduce or eliminate known or newly identified contaminants. There are currently limited regulatory mechanisms and procedures available to us for the recovery of such costs and there can be no assurance that such costs will be fully recovered and failure to do so may adversely affect our operating results.

Previous wording

For example, in April of 2024, the EPA finalized MCLs, for six PFAS in drinking water. Under the PFAS regulation, water utilities across the country are required to complete initial PFAS monitoring by 2027 and to implement treatment for sources exceeding the MCL by 2029. We estimate a capital investment of approximately $226.0 million will be required to comply with the regulation, but this amount could be higher or lower depending on factors out of our control such as unforeseen supply issues that may arise as public water systems across the country compete to procure necessary treatment supplies.

Under the PFAS regulation, water utilities across the country are required to complete initial PFAS monitoring by 2027 and to implement treatment for sources exceeding the MCL by 2029. In May of 2025, the EPA announced its intention to rescind the regulations for four of the PFAS compounds, and to extend the compliance date to 2031. On January 20, 2026, a three-judge panel of the U.S. Court of Appeals for the District of Columbia unanimously denied an EPA request to vacate and remove MCLs on four PFAS. Multi-party litigation continues with regard to PFAS MCLs. We estimate a capital investment of approximately $269.1 million will be required to comply with the currently effective regulation, but this amount could be higher or lower depending on factors out of our control such as unforeseen supply issues that may arise as public water systems across the country compete to procure necessary treatment supplies. Some of the capital investment requirements are offset and will continue to be offset by settlement and grant proceeds we have received and expect to continue to receive (see “Water Supply” above for more details).

Previous wording

Future legislation or regulation regarding climate change may restrict our operations or impose new costs on our business. Our operations depend on power provided by other public utilities and, in emergencies, power generated by our portable and fixed generators. If future legislation or regulation limits emissions from the power generation process, our cost of power may increase. Although any increase in the cost of power would be expected to be passed along to our California customers through the ICBA or included in our cost of service paid by our customers as requested in our GRC filings in California, we can give no assurance that such costs would be passed along to our California customers or that the CPUC would approve rate increases to enable us to recover such expenditures or costs.

Previous wording

Legislation and regulation regarding greenhouse gas emissions may also impose new costs on our business. For example, in October 2023, California enacted legislation addressing the disclosure of greenhouse gas emissions, climate-related risks, environmental claims, and the use or sale of voluntary carbon offsets. New and future laws and regulations, including related uncertainty from modifications to or reversals of such regulations, or inconsistency between requirements in different jurisdictions, could increase the complexity of and costs associated with compliance with such regulations, which could have a material adverse effect on our business, results of operations, and financial condition.

New and future laws and regulations, including related uncertainty from modifications to or reversals of such regulations, or inconsistency between requirements in different jurisdictions, could increase the complexity of and costs associated with compliance with such regulations, which could have a material adverse effect on our business, results of operations, and financial condition.

Previous wording

The number of environmental and service-related lawsuits against other water utilities has increased in frequency in recent years. If we are subject to additional environmental or service-related lawsuits, we might incur significant legal costs and it is uncertain whether we would be able to recover the legal costs from customers or other third parties. In addition, if current California law regarding CPUC’s preemptive jurisdiction over regulated public utilities for claims about compliance with California State Water Resources Control Board and United States EPA water quality standards changes, our legal exposure may be significantly increased.

Current wording

Environmental and service-related lawsuits have frequently been filed against other water utilities. If we are subject to additional environmental or service-related lawsuits, we could incur significant legal costs, and it is uncertain whether we would be able to recover the legal costs from customers or other third parties. In addition, if current California law regarding CPUC’s preemptive jurisdiction over regulated public utilities for claims about compliance with Water Board and EPA water quality standards changes, our legal exposure could increase significantly.

Previous wording

The California constitution may allow compensation to property owners for a public utility taking or damaging private property, even when damage occurs through no fault of the utility and regardless of whether the damage could be foreseen by the utility. As a result, this doctrine, which is known as inverse condemnation and is routinely invoked in California, imposes strict liability for damages, including legal fees, because of the design, construction, maintenance and operation of utility facilities. In addition to claims that our water or wastewater systems damaged property, Cal Water has been and could in the future be sued under inverse condemnation, including pursuant to allegations or claims that our facilities or operations damage private property, or that we are unable to timely deliver sufficient quantities of water for firefighting because of system capacity limitations or water supply disruptions, including as a result of action taken by an electric utility pursuant to a PSPS program or other loss of power. For example, accelerated land movement in Cal Water’s Rancho Dominguez District in southern California has given rise to claims and lawsuits against Cal Water, including among other allegations, inverse condemnation. Although the imposition of liability is premised on the assumption that utilities have the ability to recover these costs from their customers, there is no assurance that the CPUC would allow Cal Water to recover any such damage awards from customers. For example, in December 2017, the CPUC denied recovery of costs that San Diego Gas & Electric Company incurred because of inverse condemnation, holding that the inverse condemnation principles of strict liability are not relevant to the CPUC’s prudent manager standard.

Current wording

The effects of natural disasters, attacks by third parties, or poor water quality or contamination to our water supply or wastewater services may result in disruption in our services and litigation, which could adversely affect our business, operating results, financial condition, and reputation.

Previous wording

We operate in areas that are prone to earthquakes, urban fires, wildfires, landslides, mudslides, and other natural disasters. A significant seismic event, urban or wildfire outbreak, or other natural disaster in California where our operations are concentrated could adversely affect our ability to deliver water and adversely affect our costs of operations. A major disaster could damage or destroy substantial capital assets. For example, wildfires in our service areas may have significant impacts on water supply and water system reliability. In addition, our infrastructure faces risks from landslides in our service areas, which can lead to leaks in water mains, impact our ability to deliver water and result in litigation. For example, in Cal Water’s Rancho Dominguez District in southern California, land movement in the City of Rancho Palos Verdes has adversely impacted utility infrastructure including electric power poles and lines, natural gas mains and services and water mains and services. This land movement has impacted Cal Water assets, as well as structural, road and other property damage. The area is an active landslide complex with decades of land movement, and the Company and Cal Water believe that the recent accelerated rate of land movement is a result of an unusual and significant amount of rainfall in the area. Certain homeowners in this area have alleged Cal Water assets have contributed to ground oversaturation and land movement resulting in home and property damage. Some of these homeowners have brought claims and lawsuits against Cal Water as well as other defendants alleging inverse condemnation, among other things, and it is anticipated that other homeowners may bring similar claims in the future.

Our water supplies are subject to contamination, including contamination from the development of naturally-occurring compounds, chemicals in groundwater systems, pollution resulting from fabricated sources, such as 1,2,3-Trichloropropane (TCP) and PFAS, seawater intrusion, and possible third-party attacks, including physical attacks, terrorist attacks, and cyber-attacks. If our water supply is contaminated, we may have to interrupt the use of that water supply until we are able to substitute the flow of water from an uncontaminated water source. In addition, we may incur significant costs in order to treat the contaminated source through expansion of our current treatment facilities, or development of new treatment methods. If we are unable to substitute water supply from an uncontaminated water source, or if we are unable to adequately treat the contaminated water source in a cost-effective manner, there may be an adverse effect on our revenues, operating results, and financial condition. The costs we incur to decontaminate a water source or an underground water system could be significant and may not be recoverable in rates. We could also be held liable for consequences arising out of human exposure to hazardous substances in our water supplies or other environmental damage. For example, private plaintiffs have the right to bring personal injury or other toxic tort claims arising from the presence of hazardous substances in our drinking water supplies. Our insurance policies may not be sufficient to cover the costs of these claims.

We have taken steps to increase security measures at our facilities and heighten employee awareness of threats to our water supply, to protect against third-party attacks, including physical attacks, terrorist attacks, and cyber-attacks. We have also improved our security measures regarding the delivery and handling of certain chemicals used in our business. We have and will continue to bear increased costs for security precautions to protect our facilities, operations, and supplies. These costs may be significant. Despite these improved security measures, we may not be able to prevent or deter third-party attacks or be in a position to control the outcome of third-party attacks should they occur.

In addition, the lack of redundancy for certain of our IT systems, including billing systems, could exacerbate the impact of any of these events on us, all of which could have a negative impact on our business, results of operations, and cash flows. These types of events, either impacting our facilities or the industry in general, could also cause us to incur additional security and insurance related costs. In addition, in the ordinary course of business, we collect and retain sensitive information, including personally identifiable information, about our customers, employees, and vendors. In many cases, we outsource the administration of certain functions to vendors that have been and will continue to be targets of cyber-attacks. Any theft, loss or fraudulent use of customer, employee, vendor, or proprietary data as a result of a cyber-attack on us or a vendor could also subject us to significant litigation, liability, and costs, as well as adversely impact our reputation with customers and regulators, among others.

Current wording

These events may result in physical and/or electronic loss or compromise of customer, employee, operational, or financial data; security breaches; misappropriation; disruption of service to our customers; loss of revenues, response costs, and other financial loss; disruption of electronic monitoring and control of operational systems, disruption in normal system operations, loss of management time, attention, and resources from our regular business operations; damage to our reputation; and other adverse consequences, including liability or regulatory penalties under data privacy laws and regulations.

In addition, in the ordinary course of business, we collect and retain sensitive information, including personally identifiable information, about our customers, employees, and vendors. We must comply with federal and state privacy laws that have been passed or may be passed in the future, and they may have potential compliance obligations that impact our operations depending on whether we fall under their scope. Any actual or perceived noncompliance with applicable data privacy laws may lead to investigations, claims, and proceedings by governmental entities and private parties, damages for breach, and cause us to incur other significant costs, penalties, and other liabilities, as well as harm to our reputation. In many cases, we outsource the administration of certain functions to vendors that have been and will continue to be targets of cyber-attacks. Any theft, loss or fraudulent use of customer, employee, vendor, or proprietary data as a result of a cyber-attack on us or a vendor could also subject us to significant litigation, liability, and costs, as well as adversely impact our reputation with customers and regulators, among others. These risks may escalate during periods of heightened geopolitical tension or conflict.

In addition, we may not be successful in developing or acquiring technology that is competitive and responsive to the needs of our business, and we might lack sufficient resources to make the necessary upgrades or replacements of our outdated existing technology to allow us to continue to operate at our current level of efficiency, all of which could adversely impact our business and competitive position. We maintain cybersecurity insurance to provide coverage for a portion of the losses and damages that may result from a security breach, but such insurance is subject to a number of exclusions and may not cover the total loss caused by a breach. Other costs associated with cyber events may not be covered by insurance or recoverable in rates. The market for cybersecurity insurance continues to evolve and may affect the future availability of cybersecurity insurance at reasonable rates.

Previous wording

There is strong scientific consensus that human activity including carbon and methane emissions is impacting many planetary systems such as the heat-trapping capacity of the atmosphere; ocean temperature, circulation, acidity, and volume; weather patterns including the severity and frequency of severe weather events; ambient temperatures; and planetary ice cover. Because scientific investigations have been focused globally, there is tremendous uncertainty over the timing, extent, and types of impacts global climate change may have on our service areas and in our water supplies. Moreover, studies of tree ring data show long periods of drought conditions have occurred prior to significant human impacts in California and prior to our operation. Finally, in the last fifty years, California has experienced at least three severe multi-year droughts. We can give no assurance that any of our plans for water reliability and water shortages, including incorporating projected and potential climate change risks into our water supply planning activities, will be adequate or capable of effectively addressing any droughts or longer periods of drought conditions or other conditions affecting water quality and availability. Immediate physical risks could affect our operations and intensify over time as climate change worsens. More frequent flooding, wildfires, sea level rise, rising or falling groundwater levels, and uneven ground level sinking could damage our assets, including pressurized mains and other pipelines, wells, treatment facilities, and other infrastructure. Wildfires and changes in rainfall may also affect water quality, and both higher temperatures and wildfires can pose risks to employee safety. Farther into the mid-century and late-century horizon, temperature increases may cause declines in snowpack storage, and droughts could decrease surface water supply availability and groundwater recharge while causing increased outdoor demands, which, in each case, could adversely impact our ability to source adequate water supply to meet the needs of our customers.

Current wording

There is strong scientific consensus that human activity generates greenhouse gas emissions, which can impact planetary systems, such as the heat-trapping capacity of the atmosphere; ocean temperature, circulation, acidity, and volume; weather patterns including the severity and frequency of severe weather events; ambient temperatures; and planetary ice cover. There is tremendous uncertainty over the timing, extent, and types of impacts global climate change may have on our service areas and in our water supplies. Moreover, studies of tree ring data show long periods of drought conditions have occurred prior to significant human impacts in California and prior to our operation. Finally, in the last fifty years, California has experienced at least three severe multi-year droughts. We can give no assurance that any of our plans for water reliability and water shortages, including incorporating projected and potential climate change risks into our water supply planning activities, will be adequate or capable of effectively addressing any droughts or longer periods of drought conditions or other conditions affecting water quality and availability. Acute physical risks could affect our operations and intensify over time as climate change worsens. Flooding (surface water, coastal, river, or groundwater), wildfires, storms, and extreme heat, could disrupt our operations or damage our assets, including pressurized mains and other pipelines, wells, treatment facilities, and other infrastructure. Wildfires and flooding may also affect water quality, and extreme heat and wildfires can pose risks to employee safety. Farther into the mid-century and late-century horizon, changing temperatures (air temperature, freshwater, or marine) may cause increased algal blooms and eutrophication. Water stress, characterized by declines in snowpack storage and droughts, could decrease surface water supply availability and groundwater recharge while causing increased outdoor demands, potentially increasing operational expenses and causing challenges in maintaining affordable and reliable water service. We may also experience increased exposure to litigation associated with water quality impacts or inverse condemnation events resulting from physical climate change risks.

Previous wording

In the event that some outside factor such as a wildfire, flood, landslide, changed climate pattern, actual or threatened public health emergency, or change in the local economy reduces or eliminates our customer base in a service area, or negatively affects the ability of a customer to pay, we could face unrecoverable costs. In those circumstances, the remaining customers might not be able to pay for the operating costs or capital costs of the water system. We may not be able to recover capital costs of property that is no longer used or useful in utility service. For example, in 2024, the California Governor proclaimed the Rancho Palos Verdes landslide a state of emergency following an increase in ground movement due to significant rainfall over the past two years, and the Federal Emergency Management Agency and the California Governor’s Office of Emergency Services instituted a voluntary property buyout program for impacted homeowners. We may also encounter an increase in bad debt expense in times of economic difficulty. For example, we experienced an increase in bad debt expense in 2022, which we believe was due to the economic impact of the COVID-19 pandemic. Although we would likely seek permission to recover any such future costs through rate increases on remaining customers or in statewide rates, we can give no assurance that the Commissions would approve rate increases to enable us to recover these costs.

Wastewater collection and treatment involve many risks associated with damage to the environment, and we anticipate that wastewater collection and treatment will become an increasing significant part of our business. If collection or treatment systems fail or do not operate properly, untreated or partially treated wastewater could discharge onto property or into nearby streams and rivers, causing damage or injury to property, aquatic life, or human life. Our results of operations and financial condition could be materially and adversely affected by liabilities resulting from such damage.

The cost to obtain water for delivery to our customers varies depending on the sources of supply, wholesale suppliers’ prices, the quality of water required to be treated and the quantity of water produced to fulfill customer water demand. Our source of supply varies among our operating districts. Certain districts obtain all of their supply from wells; some districts purchase all of their supply from wholesale suppliers; and other districts obtain their supply from a combination of wells and wholesale suppliers. A small portion of supply comes from surface sources and is processed through Company-owned water treatment plants. On average, slightly more than half of the water we deliver to our customers is pumped from wells or received from a surface supply with the remainder purchased from wholesale suppliers. Water purchased from suppliers usually costs us more than surface supplied or well pumped water. The cost of purchased water for delivery to customers represented 29.7% and 31.2% of our total operating costs in 2024 and 2023, respectively. Water purchased from suppliers will require renewal of our contracts upon expiration and may result in significant price increases under any such renewed contracts.

Wholesale water suppliers may increase their prices for water delivered to us based on factors that affect their operating costs. Purchased water rate increases are beyond our control. In California, our ability to recover increases in the cost of purchased water changed with the adoption of the ICBA, which was approved as part of the 2021 GRC. With this change, actual per-unit purchased water costs are compared to authorized per-unit purchased water costs, with variances added to or netted against the variances in purchased power and pump taxes being recorded as a cost recovery. The balance in the ICBA is collected/refunded in the future by billing the ICBA accounts receivable/payable balances over future periods, which may have a short-term negative impact on cash flow.

Purchased power is a significant operating expense. During 2024 and 2023, purchased power expense represented 5.9% and 6.4%, respectively, of our total operating costs. These costs are beyond our control and can change unpredictably and substantially. As with purchased water, purchased power costs are included in the ICBA. Cash flows between rate filings may be adversely affected until the Commission authorizes a rate change. Cost of chemicals used in the delivery of water is not an element of the ICBA, and therefore, variances in quantity or cost could affect the results of operations.

Our ability to access the capital markets is affected by the ratings of certain of our debt securities. Standard & Poor’s Rating Agency issues a rating on Cal Water’s ability to repay certain debt obligations. The credit rating agency could downgrade our credit rating based on reviews of our financial performance and projections or upon the occurrence of other events that could affect our business outlook. Lower ratings by the agency could restrict our ability to access equity and debt capital. We can give no assurance that the rating agency will maintain ratings that allow us to borrow under advantageous conditions and at reasonable interest rates. A future downgrade by the agency could also increase our cost of capital by causing potential investors to require a higher interest rate due to a perceived risk related to our ability to repay outstanding debt obligations.

We rely on our current credit facilities to fund short-term liquidity needs if internal funds are not available from operations. Specifically, given the seasonal fluctuations in demand for our water we commonly draw on our credit facilities to meet our cash requirements at times in the year when demand is relatively low. We also may occasionally use letters of credit issued under our revolving credit facilities. Disruptions in the capital and credit markets could adversely affect our ability to draw on our credit facilities. Our access to funds under our credit facilities is dependent on the ability of our banks to meet their funding commitments.

Many of our customers and suppliers also have exposure to risks that could affect their ability to meet payment and supply commitments. We operate in geographic areas that may be particularly susceptible to declines in the price of real property, which could result in significant declines in demand for our products and services. In the event that any of our significant customers or suppliers, or a significant number of smaller customers and suppliers, are adversely affected by these risks, we may face disruptions in supply, significant reductions in demand for our products and services, inability of customers to pay invoices when due, and other adverse effects that could negatively affect our financial condition, results of operations and/or cash flows.

Previous wording

We seek to acquire or invest in other companies, technologies, services, or products that complement our business from time to time. The execution of our growth strategy exposes us to different risks than those associated with our utility operations. We can give no assurance that we will succeed in finding attractive acquisition candidates or investments, or that we would be able to reach mutually agreeable terms with such parties. In addition, as consolidation becomes more prevalent in the water and wastewater industries, the prices for suitable acquisition candidates may increase to unacceptable levels and limit our ability to grow through acquisitions. If we are unable to find acquisition candidates or investments, our ability to grow may be limited.

Current wording

We seek to acquire or invest in other companies that complement our business from time to time. For example, in February of 2026, we entered into an agreement to purchase Nexus’ Nevada and Oregon water and wastewater systems, which remains subject to regulatory approvals and other customary closing conditions. The execution of our growth strategy exposes us to different risks than those associated with our utility operations. We can give no assurance that we will succeed in finding attractive acquisition candidates or investments, or that we would be able to reach mutually agreeable terms with such parties. In addition, as consolidation becomes more prevalent in the water and wastewater industries and competition from other regulated utilities, governmental entities and other strategic and financial buyers continues to increase, the prices for suitable acquisition candidates may increase to unacceptable levels and limit our ability to grow through acquisitions. Consummation of any proposed acquisition at any time may also be subject to various conditions to closing as well as regulatory approvals, and there can be no assurance that we will be able to complete proposed transactions on a timely basis or at all. If we are unable to find acquisition candidates or investments, complete acquisitions of suitable candidates on attractive terms or realize the expected benefits from proposed transactions, our ability to grow may be limited.
