PART I

The Company

With a history dating back to 1886, American Water is the largest and most geographically diverse, publicly-traded water and wastewater utility company in the United States, as measured by both operating revenues and population served. A holding company originally incorporated in Delaware in 1936, the Company employs approximately 6,700 professionals who provide drinking water, wastewater and other related services to over 14 million people in 24 states. The Company conducts the majority of its business through regulated utilities that provide water and wastewater services, collectively presented as one reportable segment, referred to as the “Regulated Businesses.” The Company also operates other businesses that provide water and wastewater services to the U.S. government on military installations, as well as municipalities. Individually, these other businesses do not meet the criteria of a reportable segment in accordance with generally accepted accounting principles in the United States (“GAAP”), and are collectively presented throughout this Annual Report on Form 10-K within “Other,” which is consistent with how management assesses the results of these businesses.

Throughout this Annual Report on Form 10-K, unless the context otherwise requires, references to “we,” “us,” “our,” the “Company,” and “American Water” mean American Water Works Company, Inc. and its subsidiaries, taken together as a whole. References to “parent company” mean American Water Works Company, Inc., without its subsidiaries.

Regulated Businesses

The Company’s primary business involves the ownership of utilities that provide water and wastewater services to residential, commercial, industrial, public authority, fire service and sale for resale customers. The Company’s utilities operate in 14 states in the United States, with 3.5 million active customers in its water and wastewater networks. Services provided by the Company’s utilities are subject to regulation by multiple state utility commissions or other entities engaged in utility regulation, collectively referred to as public utility commissions (“PUCs”). Federal, state and local governments also regulate environmental, health and safety, and water quality and water accountability matters. The Company reports the results of the services provided by its utilities in the Regulated Businesses segment. Operating revenues for the Regulated Businesses were $4,296 million for 2024, $3,920 million for 2023 and $3,505 million for 2022, accounting for 92%, 93% and 92%, respectively, of the Company’s total operating revenues for the same periods.

Presented in the table below is a geographic summary of the Regulated Businesses’ operating revenues and the number of customers the Company serves, by type of service, for and as of the year ended December 31, 2024:

(a)Includes other operating revenues consisting primarily of miscellaneous utility charges, fees and rents.

(b)The Company’s “Top Five States” are determined based upon operating revenues.

(c)Includes the Company’s utility operations in the following states: Georgia, Hawaii, Indiana, Iowa, Kentucky, Maryland, Tennessee, Virginia and West Virginia and other revenue attributable collectively to the Regulated Businesses.

Customers

The Company’s Regulated Businesses have a large and geographically diverse customer base. A customer is defined as a person, business, municipality or any other entity that purchases the Company’s water or wastewater services as of the last business day of a reporting period. One single customer may purchase the Company’s services for use by multiple individuals or businesses. Examples of these customers are homes, apartment complexes, businesses and governmental entities.

The vast majority of the Company’s regulated water customers are metered, which allows the Company to measure and bill for its customers’ water usage, typically on a monthly basis. The Company employs a variety of methods of customer meter reading to monitor consumption. These methods range from meters with mechanical registers where consumption is manually recorded by meter readers, to meters with electronic registers capable of transmitting consumption data to proximity devices or via radio frequency to mobile or fixed network data collectors. The Company’s wastewater customers are billed either a flat rate or based upon their water consumption.

Residential customers make up a substantial portion of the Company’s customer base in all of the states in which it operates. The Company also serves (i) commercial customers, such as food and beverage providers, commercial property developers and proprietors, and energy suppliers, (ii) fire service customers, where the Company supplies water through its distribution systems to public fire hydrants for firefighting purposes and to private fire customers for use in fire suppression systems in office buildings and other facilities, (iii) industrial customers, such as large-scale manufacturers, mining and production operations, (iv) public authorities, such as government buildings and other public sector facilities, including schools and universities, and (v) other utilities and community water and wastewater systems in the form of bulk contracts for the supply of water or the treatment of wastewater for their own customers.

Presented in the table below is a breakout of the Company’s Regulated Businesses’ operating revenue by class of customer, for the years ended December 31, 2024, 2023 and 2022:

We operate in a market and regulatory environment that involves significant risks, many of which are beyond our control. In addition to the other information included or incorporated by reference in this Annual Report on Form 10-K, the following material factors should be considered in evaluating our business and future prospects. Any of the following risks, either alone or taken together, could materially and adversely affect our business, financial position, results of operations, cash flows and liquidity.

Risks Related to Our Industry and Business Operations

Our Regulated Businesses are subject to extensive regulation by PUCs and other regulatory agencies, which significantly affects our business, financial condition, results of operations and cash flows. Our Regulated Businesses also may be subject to fines, penalties and other sanctions for an inability to meet these regulatory requirements.

Our Regulated Businesses provide water and wastewater services to our customers through subsidiaries that are subject to regulation by PUCs. This regulation affects the rates we charge our customers and has a significant impact on our business and operations. Generally, PUCs authorize us to charge rates that they determine are sufficient to recover our prudently incurred operating expenses, including, but not limited to, operating and maintenance costs, depreciation, financing costs and taxes, and provide us with the opportunity to earn an appropriate rate of return on invested capital.

Our ability to successfully implement our business plan and strategy depends on the rates authorized by the various PUCs. We periodically file rate increase applications with PUCs. The ensuing administrative process may be lengthy and costly. Our rate increase requests may or may not be approved, or may be partially approved, and any approval may not occur in a timely manner. Moreover, a PUC may not approve a rate request in an amount that is sufficient to:

• recover our cost of operations, including: purchased water; chemicals; and fuel, power and other commodities used in our operations;

• recover our operational labor and labor-related expenses, including without limitation costs and expenses associated with our pension and other post-employment benefits;

• enable us to recover our investment; and

• provide us with an opportunity to earn an appropriate rate of return on our investment.

Approval by the PUCs is also required in connection with other aspects of our Regulated Businesses, which are required to have numerous permits, approvals and CPCNs from the PUCs that regulate their businesses and authorize acquisitions, dispositions, debt and/or equity financing, and, in certain cases, affiliated transactions. Some PUCs are empowered to impose financial penalties, fines and other sanctions for non-compliance with applicable rules and regulations. Although we believe that each utility subsidiary has obtained or sought renewal of the material permits, approvals and certificates necessary for its existing operations, we are unable to predict the impact that future regulatory activities may have on our business.

In any of these cases, our business, financial condition, results of operations, cash flows and liquidity may be adversely affected. Even if the rates approved are sufficient, we face the risk that we will not achieve the rates of return on equity permitted by PUCs. This could occur if certain conditions exist, including, but not limited to, (i) water usage is less than the level anticipated in establishing rates, (ii) customers increase their conservation efforts, (iii) we experience unusual or emergent situations, events or conditions, (iv) we experience a significant increase in customers without recovery of the operating and other costs associated with serving them, or a decrease in customers that causes a decrease in operating revenue, or (v) our investments or expenses prove to be higher than the levels estimated in establishing rates. It may be difficult to predict the outcome or impact of these events on us or the actions that may be taken by the PUCs or other governmental authorities in response thereto.

Our operations and the quality of water we supply are subject to extensive and increasingly stringent environmental, water quality and health and safety laws and regulations, including with respect to contaminants of emerging concern, compliance with which could impact both our operating costs and capital expenditures, and violations of which could subject us to substantial liabilities and costs, as well as damage to our reputation.

Our water and wastewater operations are subject to extensive federal, state and local laws and regulations. These requirements include, among others, CERCLA, the Clean Water Act, the Safe Drinking Water Act, the LCR (as amended), and each of their implementing rules and regulations, as well as other federal and state requirements. For example, PUCs and environmental regulators set conditions and standards for the water and wastewater services we deliver. We are also required to obtain various environmental permits from regulatory agencies for our operations. If the water or wastewater services we provide to our customers do not comply with regulatory standards, or otherwise violate environmental laws, regulations or permits, or other health and safety and water quality regulations, we could incur substantial fines, penalties or other sanctions or costs, as well as damage to our reputation, as a result of governmental proceedings and private litigation. In the most serious cases, regulators could reduce requested rate increases or force us

to discontinue operations and sell our operating assets to another utility or to a municipality. Given the nature of our business which, in part, involves providing water service for human consumption, any potential non-compliance with, or violation of, environmental, water quality and health and safety laws or regulations would likely pose a more significant risk to us than to a company not similarly involved in the water and wastewater industry. In addition, CERCLA authorizes the EPA to issue orders and bring enforcement actions to compel responsible parties to investigate and take remedial actions with respect to actual or threatened releases of hazardous substances, and can impose joint and several liability, without regard to fault, on responsible parties for the costs thereof. In addition, in April 2024, the EPA issued a final rule designating PFOA and PFOS as hazardous substances under CERCLA. While the EPA has stated that it will focus on holding responsible under CERCLA entities that significantly contributed to the release of PFAS into the environment, it is not yet known whether liability protection will be afforded to passive receivers of PFAS, including water and wastewater utilities.

We incur substantial operating and capital costs on an ongoing basis to comply with environmental, water quality and health and safety laws and regulations. These laws and regulations and their enforcement, have become more stringent over time, and new or stricter requirements, such as the final EPA drinking water regulations for PFAS, the LCRR and the recently implemented LCRI, are expected to increase our costs. For example, the designation of PFOA and PFOS as hazardous substances under CERCLA may impact our ability to dispose of material used to treat impacted systems and may increase our costs as a result. Although we may seek to recover ongoing compliance costs in our Regulated Businesses through customer rates, and certain jurisdictions in which our Regulated Businesses operate have passed laws authorizing recovery of such costs, there can be no guarantee that the various other regulatory PUCs or similar regulatory bodies that govern our Regulated Businesses would approve rate increases that would enable us to recover such costs or that such costs will not materially and

None.

The Company’s Cybersecurity Program

The Company’s cybersecurity program is an integral part of the long-term sustainability and effectiveness of the Company’s operational and technology environment. To protect the integrity of its data and operational and technology systems, the Company employs a “defense-in-depth” strategy that uses multiple security measures. This strategy aligns with the National Institute of Standards and Technology Cyber Security Framework and provides preventative, detective, and responsive measures to identify and manage risks. The Company periodically reviews and modifies the implementation of its cybersecurity strategy based on threat trends, program maturity, the results of assessments, and the advice of third-party security consultants.

The Company’s cybersecurity program includes the following areas of focus:

• Technology that includes, among other things, encryption, threat management, monitoring, investigation support and backups for physical devices, such as mobile phones and computers, connected to the Company network;

• Identity and access management controls that include, among other things, multi-factor authentication and safeguards associated with granting elevated privileges;

• Proactive cybersecurity processes, including vulnerability scanning, penetration testing and periodic program assessments by outside security consultants and assessors;

• Reactive cybersecurity processes that are regularly evaluated using various incident response and disaster recovery exercises;

• Employee cyber risk awareness and training, including regular simulation exercises with employees, that covers cybersecurity threats and actions to prevent and report attacks; and

• Third-party risk management and security standards, including due diligence, continuous monitoring, cyber risk scoring and contractual obligations, and periodic review of third-party control environments to align the Company’s risk exposure with its business requirements and risk tolerances.

Third-Party Relationships

The Company utilizes partners and third-party service providers to help deliver safe and reliable water and wastewater services across its regulated operations and has implemented a third-party risk management program to understand the cybersecurity risks to the Company that may arise out of these third-party relationships. The Company categorizes third-party relationships by risk level, which is determined primarily by the service provided by the third-party and its level of access to the Company’s data. Each category has specific cybersecurity controls, data privacy and documentation requirements, which are outlined in the agreement between the Company and the third-party service provider. In addition, the Company evaluates the online security footprint for its service providers at the time of agreement, and on a regular basis, thereafter, depending on the provider’s risk level. The Company reviews its agreements with third-party service providers periodically related to terms and conditions governing cybersecurity controls and data privacy. The Company also monitors, as appropriate, risks relating to potential compromises of sensitive Company information through third parties and reevaluates these risks periodically. In addition, the Company obtains annual attestation reports related to data security and privacy from certain third-party providers to further support compliance with industry-standard cybersecurity protocols.

Cybersecurity Risks

Cybersecurity threats are constantly evolving and have and will continue to become more frequent and sophisticated. Although the Company has implemented measures that it believes are reasonable to safeguard its operational and information technology systems and has sought to establish a culture of continuous monitoring and improvement, the evolving and increasingly complex nature of cybersecurity attacks and vulnerabilities means that these protections may not always be effective. By way of example, as previously disclosed, on October 3, 2024, the Company identified unauthorized activity within its information technology computer networks and systems, which was determined to be the result of a cybersecurity incident. To date, the Company has determined that it has not experienced a cybersecurity incident that has resulted in a material impact to the Company’s financial condition, results of operations, cash flows, or business strategy. For additional information concerning the October 3, 2024, cybersecurity incident, and cybersecurity-related risks, see Item 1A—Risk Factors—Risks Related to Our Industry and Business Operations—We are, and may in the future be, subject to physical and cyber attacks, and —We may sustain losses that exceed or are excluded from our insurance coverage or for which we are self-insured; and Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Other Matters—Cybersecurity Incident.

Cybersecurity Risk Management and Strategy

The Company has established an enterprise-wide cybersecurity program designed to prevent disruption to critical information systems, minimize the loss or manipulation of sensitive information, and to timely identify, escalate and promptly remediate and recover from cybersecurity incidents and facilitate compliance with regulatory and disclosure requirements. To oversee cybersecurity risk management, the Company employs a dedicated unit, led by the Company’s Chief Information Security Officer (“CISO”), to implement cybersecurity controls, assess and report on cybersecurity risks and consult with the Company’s internal Enterprise Risk Management Committee, a decision-making body which supports and oversees the identification, assessment, prioritization, and mitigation strategies for enterprise-level risks, including cybersecurity risks. The CISO has over 25 years of work experience in the information technology, physical security and cybersecurity fields, including previously serving as the Company’s Chief Security Officer, and holds the Certified Protection Professional, Professional Certified Investigator and Physical Security Professional certifications from ASIS International. The CISO serves on the Water Sector Coordinating Council (“WSCC”), an advisory body comprised of representatives from various U.S. water and wastewater organizations, which serves as a policy, strategy and coordination mechanism for the water sector on critical infrastructure security and resilience issues. In that role, the CISO partners with representatives from the Department of Homeland Security and the EPA on U.S. water and wastewater sector initiatives. The CISO is also the former Chair of the WSCC, the National Association of Water Companies’ Safety and Security Committee, and the ASIS Utility Security Council. The CISO reports directly to the Company’s Chief Technology and Information Officer, who is responsible for the Company’s information technology program.

The Company’s security team provides oversight and policy guidance on physical, cyber and information security, as well as business continuity, throughout the Company’s operations. It is responsible for designing, implementing, monitoring and supporting effective physical and technical security controls for the Company’s physical assets, business systems and operational technologies. The Company’s security team also conducts annual and ongoing cybersecurity awareness training and education for the Company’s employees. In 2024, 100% of the Company’s active workforce completed mandatory cybersecurity training. By equipping employees with knowledge and skills, the Company strives to cultivate and maintain a cybersecurity-conscious culture within its workforce.

The Company’s cybersecurity risk assessment process involves considering risks associated with the nature of its business, receiving and processing inputs from internal and external stakeholders, monitoring industry trends and risks and engaging external advisors, to assist in aligning the Company’s cybersecurity processes with industry best practices. Risk assessments are conducted quarterly and annually to evaluate the effectiveness of the Company’s existing security controls and serve as the basis for additional safeguards, security controls and measures. Operational and technical security controls are deployed and integrated as safeguards against unauthorized access to the Company’s information systems. These controls are aimed at (i) assuring the continuity of business processes that are dependent upon automation, (ii) maintaining the integrity of the Company’s data, (iii) supporting regulatory and legislative compliance requirements, and (iv) maintaining safe and reliable service to the Company’s customers.

The Company has also implemented a vulnerability assessment program that is reviewed at least annually and more frequently, depending on changes to the risk environment. This process serves as a guiding enterprise-wide framework to outline the scope and procedures of the Company’s cybersecurity risk management processes. By prioritizing vulnerability management and continuously evaluating the Company’s internal and external environments for vulnerabilities, the Company aims to implement preventative measures to protect its information assets and technology-based infrastructure from cybersecurity threats. This approach helps to reduce the Company’s exposure to material cybersecurity threat risks.

Incident Response

The Company utilizes an established internal framework designed to assess promptly the severity and materiality of cybersecurity incidents based on predefined quantitative and qualitative criteria and to determine the appropriate level of response. Incidents are escalated to the relevant management teams based on their severity and materiality for prompt response and mitigation. The Company maintains a standing crisis response team comprised of individuals from various functional units, including without limitation Information Technology, Legal, Finance, Enterprise Risk Management, Operations and Communications, to respond to cybersecurity and physical security incidents, environmental incidents and health and safety emergencies, among others.

When a cybersecurity incident occurs, the Company establishes a cross-functional incident response team to respond to the specific cybersecurity incident. The incident response team consists of a subset of members from the standing crisis response team, including personnel with the most relevant experience related to the specific incident. This collaborative approach is intended to enable the Company to leverage expertise throughout the business to address cybersecurity events and to evaluate the potential financial, legal, operational and reputational implications of an incident, or series of related incidents. In considering the materiality of an event, related attacks, whether in terms of quantity or impact, are reviewed individually and in the aggregate to determine whether they may have a significant impact on the Company’s financial condition, results of operations or business strategy, either quantitatively or qualitatively.

Cybersecurity Governance

The Board of Directors is responsible for oversight of the Company’s cybersecurity program and the Company’s responses to cybersecurity risk. The Board of Directors has delegated to its SETO Committee responsibility for the oversight and review of technology policy, strategy and governance, and cybersecurity issues that could impact the Company’s operational performance or risk profile. The SETO Committee meets at least quarterly and receives reports related to cybersecurity threats, trends and risks, and related mitigation activities. In addition, the SETO Committee and the Board of Directors receive reports of periodic external assessments and internal testing of the effectiveness of the Company’s cybersecurity program. The SETO Committee coordinates with the Audit, Finance and Risk Committee, as appropriate, on matters related to cybersecurity risk. The Audit, Finance and Risk Committee is responsible for, among other things, overseeing the adequacy and effectiveness of the Company’s system of internal controls and the Company’s risk assessment and management strategy, including with respect to cybersecurity risks.

The Company’s properties consist primarily of (i) water and wastewater treatment plants, (ii) mains and pipes used for transmission, distribution and collection of water and wastewater, (iii) wells and other sources of water supply, such as reservoirs, (iv) water and wastewater pumping stations, (v) meters and fire hydrants, (vi) general structures, including buildings, dams and treated water storage facilities, (vii) land and easements, (viii) vehicles, (ix) software rights, and (x) other equipment and facilities, the majority of which are used directly in the operation of its systems. Substantially all of the Company’s properties are owned by its subsidiaries, with a large percentage subject to liens of its mortgage bonds. A wholly owned subsidiary of parent company owns the Company’s corporate headquarters, located in Camden, New Jersey, and the Company and its operating subsidiaries lease office space, equipment and furniture from certain of the Company’s wholly owned subsidiaries. These properties are utilized by the Company’s directors, officers and staff in the conduct of the business.

The properties of the Company’s Regulated Businesses consist mainly of approximately:

• 80 surface water treatment plants;

• 520 groundwater treatment plants;

• 190 wastewater treatment plants;

• 54,500 miles of transmission, distribution and collection mains and pipes;

• 1,200 groundwater wells;

• 1,800 water and wastewater pumping stations;

• 1,100 treated water storage facilities; and

• 75 dams.

The Company has ongoing infrastructure renewal programs in all states in which its Regulated Businesses operate. These programs consist of both the rehabilitation of existing mains and equipment, and the replacement of mains and equipment that have been damaged or have reached, or are near, the end of their useful service lives. The properties within Other consist mainly of office furniture and IT equipment. Approximately 50% of all properties that the Company owns are located in New Jersey and Pennsylvania.

The Company maintains property insurance against loss or damage to its properties by fire or other perils, subject to certain exceptions. For insured losses, the Company is self-insured to the extent that any losses are within the policy deductible or exceed the amount of insurance maintained.

The Company believes that its properties are generally maintained in good operating condition and in accordance with current standards of good water and wastewater industry practice.

Set forth below is information related to the Company’s material pending legal proceedings as of February 19, 2025, other than ordinary routine litigation incidental to the business, required to be disclosed in this Annual Report on Form 10-K. The information below should be read together with Note 16—Commitments and Contingencies in the Notes to the Consolidated Financial Statements. In accordance with the SEC’s disclosure rules, the Company has elected to disclose environmental proceedings involving the Company and a governmental authority if the amount of potential monetary sanctions, exclusive of interest and costs, that the Company reasonably believes will result from such proceeding is $1 million or more**.**

Alternative Water Supply in Lieu of Carmel River Diversions

Compliance with SWRCB Orders to Reduce Carmel River Diversions

Under the 2009 Order, Cal Am is required to decrease significantly its yearly diversions of water from the Carmel River according to a set reduction schedule. See Item 1—Business—Regulated Businesses—Water Supply and Wastewater Services and Item 1A—Risk Factors. The 2009 Order responded to claims that Cal Am had not sufficiently implemented actions to terminate its unpermitted diversions of water from the Carmel River as required by the 1995 Order issued by the SWRCB. In July 2016, at the request of Cal Am and several Monterey County government agencies, the SWRCB issued the 2016 Order approving a deadline of December 31, 2021, for Cal Am’s compliance with the 2009 Order.

The 2009 Order includes a condition prohibiting Cal Am from diverting water from the Carmel River for new service connections or for any increased use of water at existing service addresses resulting from a change in zoning or use. In 2011, the California Public Utilities Commission (the “CPUC”) issued a decision directing modifications in Cal Am’s tariffs to recognize the moratorium mandated by the 2009 Order, and directing Cal Am to seek written guidance from the SWRCB with respect to any unresolved issues of interpretation or implementation of this condition. In 2012, the Deputy Director of the SWRCB sent a letter to Cal Am providing an interpretation as to the calculation of a baseline to determine increases in use of water at existing service addresses. In March 2018, the MPWMD adopted a resolution directing Cal Am to interpret the baseline in a manner that conflicts with the SWRCB’s written interpretation. In May 2018, Cal Am notified the MPWMD and the SWRCB that it intends to seek declaratory relief concerning the conflicting regulatory interpretations under the 2009 Order. In an attempt to resolve these conflicting interpretations prior to seeking judicial intervention, Cal Am has met with the MPWMD and the SWRCB several times. The SWRCB agreed to circulate revisions to its 2012 interpretive letter, which would be subject to a public comment period. Any failure to follow the MPWMD’s resolution or the SWRCB’s written interpretation, despite these conflicting interpretations, could potentially result in fines, penalties and other actions against Cal Am.

Following issuance by the California Coastal Commission (the “Coastal Commission”) in November 2022, of a coastal development permit, as described below, Cal Am continues to work constructively with all appropriate agencies to obtain the remaining required permits for the Water Supply Project. However, there can be no assurance that the Water Supply Project in its current configuration will be completed on a timely basis, if ever. For the year ended December 31, 2024, Cal Am has complied with the diversion limitations contained in the 2016 Order. Continued compliance with the diversion limitations in 2025, and future years may be impacted by a number of factors, including without limitation potential recurrence of drought conditions in California and the reduction or exhaustion of water supply reserves, and will require successful development of alternate water supply sources sufficient to meet customer demand. The 2009 Order and the 2016 Order remain in effect until Cal Am certifies to the SWRCB, and the SWRCB concurs, that Cal Am has obtained a permanent supply of water to substitute for past unauthorized Carmel River diversions. While the Company cannot currently predict the likelihood or result of any adverse outcome associated with these matters, further attempts to comply with the 2009 Order and the 2016 Order in the future may result in material additional costs and obligations to Cal Am, including fines and penalties against Cal Am in the event of noncompliance with the 2009 Order and the 2016 Order.

Monterey Peninsula Water Supply Project

CPUC Final Approval of Water Supply Project

Cal Am’s ability to move forward on the Water Supply Project is and has been subject to extensive administrative review by the CPUC and other government agencies, obtaining necessary permits, and intervention from other parties. In 2016, the CPUC unanimously approved a final decision to authorize Cal Am to enter into a water purchase agreement for the GWR Project and to construct a pipeline and pump station facilities and recover up to $50 million in associated incurred costs plus AFUDC, subject to meeting certain criteria.

In 2018, the CPUC unanimously approved another final decision finding that the Water Supply Project meets the CPUC’s requirements for a CPCN and an additional procedural phase was not necessary to consider alternative projects. The CPUC’s 2018 decision concludes that the Water Supply Project is the best project to address estimated future water demands in Monterey, and, in addition to the cost recovery approved in its 2016 decision, adopts Cal Am’s cost estimates for the Water Supply Project, which amounted to an aggregate of $279 million plus AFUDC at a rate representative of Cal Am’s actual financing costs. The 2018 final decision specifies the procedures for recovery of all of Cal Am’s prudently incurred costs associated with the Water Supply Project upon its completion, subject to the frameworks included in the final decision related to cost caps, O&M costs, financing, ratemaking and contingency matters. The reasonableness of the Water Supply Project costs will be reviewed by the CPUC when Cal Am seeks cost recovery for the Water Supply Project. Cal Am is also required to implement mitigation measures to avoid, minimize or offset significant environmental impacts from the construction and operation of the Water Supply Project and comply with a mitigation monitoring and reporting program, a reimbursement agreement for CPUC costs associated with that program, and reporting requirements on plant operations following placement of the Water Supply Project in service. Cal Am has incurred $281 million in aggregate costs as of December 31, 2024, related to the Water Supply Project, which includes $88 million in AFUDC.

In September 2021, Cal Am, Monterey One Water and the MPWMD reached an agreement on Cal Am’s purchase of additional water from an expansion to the GWR Project, which is not expected to produce additional water until late 2025 at the earliest. The amended and restated water purchase agreement for the GWR Project expansion is subject to review and approval of the CPUC, and in November 2021, Cal Am filed an application with the CPUC that sought review and approval of the amended and restated water purchase agreement. Cal Am also requested rate base treatment of the additional capital investment for certain Cal Am facilities required to maximize the water supply from the expansion to the GWR Project and a related Aquifer Storage and Recovery Project, totaling approximately $81 million. This requested amount was in addition to, and consistent in regulatory treatment with, the prior $50 million of cost recovery for facilities associated with the original water purchase agreement, which was approved by the CPUC in its unanimous 2016 final decision.

On December 5, 2022, the CPUC issued a final decision that authorized Cal Am to enter into the amended water purchase agreement, and specifically to increase pumping capacity and reliability of groundwater extraction from the Seaside Groundwater Basin. The final decision sets the cost cap for the proposed facilities at approximately $62 million. Cal Am may seek recovery of amounts above the cost cap in a subsequent rate filing or general rate case. Additionally, the final decision authorizes AFUDC at Cal Am’s actual weighted average cost of debt for most of the facilities.

On December 30, 2022, Cal Am filed with the CPUC an application for rehearing of the CPUC’s December 5, 2022 final decision, and on March 30, 2023, the CPUC issued a decision denying Cal Am’s application for rehearing but adopting its proposed AFUDC for already incurred and future costs. The decision also provided Cal Am the opportunity to serve supplemental testimony to increase its cost cap for certain of the Water Supply Project’s extraction wells. The amended water purchase agreement and a memorandum of understanding to negotiate certain milestones related to the expansion of the GWR Project have been signed by the relevant parties. Further hearings were scheduled in a Phase 2 to this CPUC proceeding to focus on updated supply and demand estimates for the Water Supply Project, and Phase 2 testimony was completed in September 2022. On October 23, 2023, a status conference was held to determine procedural steps to conclude the proceeding. Further evidentiary hearings in this proceeding were held in March 2024. This matter remains pending.

While Cal Am believes that its expenditures to date have been prudent and necessary to comply with the 2009 Order and the 2016 Order, as well as relevant final decisions of the CPUC related thereto, Cal Am cannot currently predict its ability to recover all of its costs and expenses associated with the Water Supply Project and there can be no assurance that Cal Am will be able to recover all of such costs and expenses in excess of the $112 million in aggregate construction costs, plus applicable AFUDC, previously approved by the CPUC in its 2016 and December 2022 final decisions, as amended by its March 30, 2023, rehearing decision. See Note 16—Commitments and Contingencies in the Notes to the Consolidated Financial Statements for further discussion.

Coastal Development Permit Application

In 2018, Cal Am submitted a coastal development permit application (the “Marina Application”) to the City of Marina (the “City”) for those project components of the Water Supply Project located within the City’s coastal zone. Members of the City’s Planning Commission, as well as City councilpersons, have publicly expressed opposition to the Water Supply Project. In May 2019, the City issued a notice of final local action based upon the denial by the Planning Commission of the Marina Application. Thereafter, Cal Am appealed this decision to the Coastal Commission, as permitted under the City’s code and the California Coastal Act. At the same time, Cal Am submitted an application (the “Original Jurisdiction Application”) to the Coastal Commission for a coastal development permit for those project components located within the Coastal Commission’s original jurisdiction. After Coastal Commission staff issued reports recommending denial of the Original Jurisdiction Application, noting potential impacts on environmentally sensitive habitat areas and wetlands and possible disproportionate impacts to communities of concern, in September 2020, Cal Am withdrew the Original Jurisdiction Application in order to address the staff’s environmental justice concerns. In November 2020, Cal Am refiled the Original Jurisdiction Application.

In October 2022, Cal Am announced a phasing plan for the proposed desalination plant component of the Water Supply Project. The desalination plant and slant wells originally approved by the CPUC would produce up to 6.4 million gallons of desalinated water per day. Under the phased approach, the facilities would initially be constructed to produce up to 4.8 million gallons per day of desalinated water, enough to meet anticipated demand through about 2030, and would limit the number of slant wells initially constructed. As demand increases in the future, desalination facilities would be expanded to meet the additional demand. The phased approach seeks to meet near-term demand by allowing for additional supply as it becomes needed, while also providing an opportunity for regional future public participation and was developed by Cal Am based on feedback received from the community.

In November 2022, the Coastal Commission approved the Marina Application and the Original Jurisdiction Application with respect to the phased development of the proposed desalination plant, subject to compliance with a number of conditions, all of which Cal Am expects to satisfy. Cal Am continues to seek the remaining permits necessary to construct the Water Supply Project.

In December 2022, the City, Marina Coast Water District (“MCWD”), MCWD’s groundwater sustainability agency (“GSA”), and the MPWMD jointly filed a petition for writ of mandate in Monterey County Superior Court against the Coastal Commission, alleging that the Coastal Commission violated the California Coastal Act and the California Environmental Quality Act in issuing a coastal development permit to Cal Am for construction of slant wells for the Water Supply Project. Cal Am is named as a real party in interest. On April 24, 2024, the court granted defendants’ motion for judgment on the pleadings and dismissed one of MCWD’s causes of action in its petition. A trial commenced on December 9, 2024, and further proceedings continued in January 2025. This matter remains pending.

Subject to the impact or resolution of this litigation, construction of the desalination plant is expected to begin in 2025 and the desalination plant is estimated to be in-service by the end of 2027.

Proposed Zoning Changes at CEMEX, Inc. Site for Slant Wells

In August 2018, the City circulated a public review draft of proposed amendments to its local coastal program and zoning ordinance, and placed the matter for consideration on the Planning Commission’s agenda for its September 2018 meeting. The proposed amendments would change zoning at a site owned by CEMEX, Inc. (“CEMEX”) to open space and restrict future uses, including with respect to Cal Am’s planned use of the site for the slant wells for the Water Supply Project. Any change to the City’s local coastal program must ultimately be approved by the Coastal Commission. Cal Am, CEMEX and the Coastal Commission each submitted letters opposing the proposed amendments. At its November 2018 meeting, the Planning Commission adopted a resolution recommending that the Marina City Council consider approving the amendments.

In December 2018, the Marina City Council considered the proposed amendments. Cal Am, CEMEX and the Coastal Commission again submitted letters opposing the proposed changes, but the City Council unanimously adopted a resolution amending its local coastal plan and a draft amendment to its zoning ordinance. Changes to the ordinance require a second reading before becoming final, which occurred at the City’s December 2018 meeting. The changes to the local coastal plan would need to be submitted to the Coastal Commission for approval; however, the Coastal Commission’s November 2022 approval of Cal Am’s coastal development permit application has rendered moot the impact of these proposed local coastal program and zoning changes on the issuance of the coastal development permit.

Test Slant Well Permitting

A preliminary step to building the Water Supply Project desalination plant is the construction and operation of a test slant well to confirm the suitability of the property on which intake wells will be located to draw water from under Monterey Bay. In November 2014, the Coastal Commission approved coastal development permits for the test slant well, enabling Cal Am to construct and operate the test slant well. Effective February 28, 2018, test slant well pumping ceased, except for minimal maintenance pumping activities, in accordance with Cal Am’s coastal development permits. Because Cal Am may use the test slant well as one of the slant wells for the Water Supply Project, Cal Am sought and obtained from the Coastal Commission permit amendments to allow the test slant well to remain in place and be maintained until February 28, 2026. A required lease obtained from the California State Lands Commission, as amended, expires on December 16, 2027.

Water Supply Project Land Acquisition and Slant Well Site Use

In July 2017, the Coastal Commission adopted a consent agreement and cease and desist order requiring sand mining operations on the property owned by CEMEX on which intake wells for the Water Supply Project will be located, to cease by the end of 2020 and the property to be sold to either a non-profit or governmental entity. The consent agreement strictly limits future use of the property but preserves Cal Am’s existing property rights and allows uses consistent with existing easements and other rights of record. A permanent easement granted by CEMEX to Cal Am was recorded in June 2018 to allow Cal Am access to the property and to construct, operate and maintain the Water Supply Project intake wells. In November 2019, the City notified CEMEX that, based on this permanent easement and Cal Am’s proposed use of the site for the intake wells, CEMEX has breached or will soon breach a prior 1996 annexation agreement (to which Cal Am was not a party). The City states that it intends to seek declaratory relief from CEMEX and Cal Am ordering that Cal Am’s extraction is limited to 500 acre-feet per year of groundwater, that Cal Am cannot export extracted water out of the basin, and that the permanent easement granted by CEMEX to Cal Am is void. CEMEX has denied the City’s claims and requested indemnification from Cal Am under the terms of the permanent easement. Cal Am and CEMEX believe that there is no valid limitation under the annexation agreement on Cal Am’s right to pump brackish groundwater and seawater at the site for desalination and use by Cal Am’s customers.

In May 2020, the City filed a lawsuit in Monterey County Superior Court, naming Cal Am and CEMEX as defendants, and Monterey County Water Resources Agency (“MCWRA”) and MCWD as real parties in interest. The lawsuit, as amended, alleges a claim for breach of contract against CEMEX and seeks declaratory relief to void the permanent easement and prohibiting extraction of water by Cal Am’s slant wells at the CEMEX site in excess of 500 acre-feet per year and the export of such water outside the groundwater basin. In November 2020, Cal Am, CEMEX and MCWRA filed demurrers, which were overruled by the court at a hearing held in February 2021.

In August 2020, MCWD filed a cross-complaint in the May 2020 lawsuit against Cal Am, CEMEX and MCWRA, alleging claims for specific performance of certain provisions of the 1996 annexation agreement related to the property owned by CEMEX on which intake wells for the Water Supply Project will be located, as well as claims of water rights, nuisance and unreasonable water use, and seeking additional declaratory relief. Following various rulings on demurrers filed by Cal Am, CEMEX and MCWRA, in February 2021, the court sustained, without leave to amend, the demurrer to MCWD’s nuisance claim and overruled the remainder of the demurrers. In October 2021, the court granted a motion filed by Cal Am related to MCWD’s cross-complaint, which motion requested a referral of certain issues related to MCWD’s water rights and unreasonable use claims to the SWRCB for its expert advisory opinion. The SWRCB held hearings in 2022 and 2023, on the referred issues before its administrative hearing officer. On September 19, 2024, the SWRCB administrative hearing officer sent a letter to the court advising that the full draft report of the SWRCB advisory opinion addressing the questions referred by the court would not be received until at least November 1, 2024. On November 22, 2024, the administrative hearing officer sent a second letter to the court advising that the draft report would be considered for approval at a public meeting of the SWRCB to be held in the first quarter of 2025. On December 31, 2024, an initial draft report was circulated by the SWRCB to the parties for review and comment.

Regional Water Quality Control Board Approval of NPDES Permit Amendment

A requirement of the desalination plant that is a key component of the Water Supply Project is the discharge of brine through Monterey One Water’s outfall. As a condition to Cal Am’s coastal development permit, an amendment of a NPDES permit must be obtained by Monterey One Water as the outfall owner from the Regional Water Quality Control Board (the “RWQCB”). The RWQCB must also determine that the proposed brine discharge complies with the desalination facility requirements under the California Ocean Plan. Working in cooperation with Monterey One Water staff and consultants, Cal Am prepared an application for submission to the RWQCB, which application and submission were approved by Monterey One Water's Board on September 30, 2024.

Challenges Related to Compliance with California’s Sustainable Groundwater Management Act

Under California’s Sustainable Groundwater Management Act (“SGMA”) enacted in 2015, groundwater basins designated by the state as critically overdrafted must be managed by a GSA by 2020 in accordance with an approved groundwater sustainability plan (“GSP”) designed to achieve sustainability by 2040. Under the SGMA, GSAs have broad powers to achieve sustainability including, but not limited to, regulating groundwater extraction by imposing fees on groundwater extractions and controlling groundwater extractions by regulating, limiting or suspending extractions from wells. The 400-acre CEMEX site overlies a small portion of the 180/400 Subbasin of the Salinas Valley Groundwater Basin; the 84,000-acre 180/400 Subbasin has been designated by the state as critically overdrafted, mainly due to seawater intrusion into the subbasin.

In late 2016, the Salinas Valley Basin Groundwater Sustainability Agency (the “SVBGSA”) was formed as a joint powers authority to become the GSA for the Salinas Valley Groundwater Basin and prepare a GSP. In April 2018, the City filed a notice to become the GSA for the CEMEX site, creating an overlap with the SVBGSA’s filing for the 180/400 Subbasin. In 2016, the SVBGSA commenced preparation of a GSP covering the entire 180/400 Subbasin, including the CEMEX site, but in August 2019 the City filed a notice that it intends to prepare its own GSP for the CEMEX site with the intent to severely limit or prohibit groundwater pumping at that site. The State Department of Water Resources (“SDWR”) has taken the position that until the overlap is resolved, it will not accept the GSP from either agency, placing the subbasin at risk of being placed in a probationary status and subject to state management. In December 2019, the County of Monterey filed its own notice to become the exclusive GSA at the CEMEX site in order to resolve the overlap, which is permitted under SGMA. SDWR accepted Monterey County’s filing in December 2019, and now lists Monterey County as the exclusive GSA for the site.

In December 2019, the City filed a lawsuit in Monterey County Superior Court challenging Monterey County’s filing, and SDWR’s acceptance of the filing, as the exclusive GSA for the CEMEX site. The City has named Monterey County and its Board of Supervisors, its GSA, and SDWR and its director as defendants, and the SVBGSA and its Board of Directors as real parties. The City seeks to invalidate Monterey County’s filing, as well as injunctive relief to preserve the City’s status as a GSA for the site. To protect its interest in the matter, Cal Am filed an application to intervene in this lawsuit, which was granted. Monterey County filed cross-claims against the City and SDWR. In September 2020, Cal Am filed a separate but related complaint in Monterey County Superior Court challenging the validity of actions taken by the City and its GSA in adopting a groundwater sustainability plan for the CEMEX site, and the validity of the provisions of such plan. Due to the overlap of issues in the City’s lawsuit with those in the validation action, the parties stipulated to a stay of the validation action pending determination of the claims in the City’s action, which was approved by the court in December 2020. In February 2021, the City filed a separate but related in rem reverse validation complaint challenging the adoption by Monterey County of a GSP for the CEMEX site. On May 3, 2023, the City filed a second reverse validation complaint, challenging the adoption of amendments to the GSP for the 180/400 Subbasin.

After a hearing, in August 2021, the court denied the claims brought by the City and granted Monterey County’s cross-claims, finding that the City’s GSA notice was untimely, the Monterey County GSA was the exclusive GSA for the CEMEX site, and the SVBGSA’s GSP was properly adopted for the entire 180/400 Subbasin, including the CEMEX site. In November 2021, the City appealed this decision, and in December 2021, Monterey County appealed the court’s decision as to the finding that the City’s action creating a GSA was not void. The related validation and reverse validation actions remain stayed during the pendency of the appeal. On November 13, 2023, the California Court of Appeal affirmed the trial court's decision. On December 22, 2023, the City filed a petition for review with the California Supreme Court, which was denied on February 24, 2024. On October 31, 2024, the parties entered into an agreement settling the stayed validation complaints and all claims for attorneys’ fees and costs. The validation complaints were subsequently dismissed.

Cal Am’s Action for Damages Following Termination of Regional Desalination Project (“RDP”)

In 2010, the CPUC had approved the RDP, which was a precursor to the current Water Supply Project and called for the construction of a desalination facility in the City of Marina. The RDP was to be implemented through a Water Purchase Agreement and ancillary agreements (collectively, the “Agreements”) among MCWD, Cal Am and MCWRA. In 2011, due to a conflict of interest concerning a former member of MCWRA’s Board of Directors, MCWRA stated that the Agreements were void, and, as a result, Cal Am terminated the Agreements. In ensuing litigation filed by Cal Am in 2012 to resolve the termination of the RDP, the court in 2015 entered a final judgment agreeing with Cal Am’s position that four of the five Agreements are void, and one, the credit line agreement, is not void. As a result of this litigation, Cal Am was permitted to institute further proceedings, discussed below, to determine the amount of damages that may be awarded to Cal Am as a result of the failure of the RDP.

In 2015, Cal Am and MCWRA filed a complaint in San Francisco County Superior Court against MCWD and RMC Water and Environment, a private engineering consulting firm (“RMC”), seeking to recover compensatory, consequential and incidental damages associated with the failure of the RDP, as well as punitive and treble damages, statutory penalties and attorneys’ fees. In 2019, MCWD was granted a motion for summary judgment related to the tort claims in the complaint. A settlement as to the non-tort claims was finalized and entered into in March 2020, in which MCWD and RMC paid Cal Am an aggregate of $5.2 million to resolve Cal Am’s contract claims against MCWD and all claims against RMC relating to the RDP. Under this agreement, Cal Am’s and MCWRA’s right to appeal the dismissal of their tort claims against MCWD were expressly reserved.

In July 2020, Cal Am appealed the grant of summary judgment on MCWD’s tort claims, and in December 2022, the trial court’s decision was reversed on appeal with instructions to vacate its prior orders granting MCWD’s motions for summary judgment and to enter new orders denying the motions. In February 2023, MCWD filed a petition for review of the appellate decision with the California Supreme Court, which was denied in March 2023. On June 27, 2024, MCWD filed a motion for judgment on the pleadings. Following a hearing, on December 5, 2024, the court granted MCWD’s motion without leave to amend, dismissing all of Cal Am’s remaining claims. Final judgment was entered on January 7, 2025. Cal Am intends to file a notice of appeal of the trial court’s decision.

Proposed Acquisition of Monterey System Assets — Potential Condemnation

Local Agency Formation Commission Litigation

In November 2018, voters in Monterey, California passed “Measure J,” which decided that the MPWMD should conduct a feasibility study concerning the potential purchase of Cal Am’s Monterey system assets, and, if feasible, to proceed with a purchase of those assets without an additional public vote. This service territory represents approximately 40,000 customers. In 2019, the MPWMD issued a preliminary valuation and cost of service analysis report, finding in part that (i) an estimate of the Monterey system assets’ total value plus adjustments would be approximately $513 million, (ii) the cost of service modeling results indicate significant annual reductions in revenue requirements and projected monthly water bills, and (iii) the acquisition of the Monterey system assets by the MPWMD would be economically feasible. In 2020, the MPWMD certified a final environmental impact report, analyzing the environmental impacts of the MPWMD’s project to (i) acquire the Monterey system assets through the power of eminent domain, if necessary, and (ii) expand its geographic boundaries to include all parts of this system.

In February 2021, the MPWMD filed an application with the Local Agency Formation Commission of Monterey County (“LAFCO”) seeking approval to become a retail water provider and annex approximately 58 parcels of land into the MPWMD’s boundaries. In June 2021, LAFCO’s commissioners voted to require a third-party independent financial study as to the feasibility of an acquisition by the MPWMD of the Monterey system assets. In December 2021, LAFCO’s commissioners denied the MPWMD’s application to become a retail water provider, determining that the MPWMD does not have the authority to proceed with a condemnation of the Monterey system assets. In April 2022, the MPWMD filed a lawsuit against LAFCO challenging its decision to deny the MPWMD’s application seeking approval to become a retail water provider. In June 2022, the court granted, with conditions, a motion by Cal Am to intervene in the MPWMD’s lawsuit against LAFCO. In December 2022, the court sustained in part, and denied in part, demurrers that had been filed by LAFCO seeking to dismiss the MPWMD’s lawsuit.

On December 11, 2023, the Monterey County Superior Court issued a writ of mandate directing LAFCO to vacate and set aside its original denial of the MPWMD’s application to serve as a retail water provider (in conjunction with its effort to acquire the Monterey system assets) and, if requested, to re-hear the application in compliance with all applicable law. The court held that LAFCO incorrectly applied two statutory standards and noted a lack of sufficient evidence to support certain of LAFCO’s factual findings. As a result, the LAFCO denial has been nullified and LAFCO will be required to hold another hearing on the MPWMD’s application. On February 8, 2024, and February 9, 2024, respectively, each of Cal Am and LAFCO filed a notice of appeal with the California Court of Appeal regarding the Monterey County Superior Court’s decision to issue the writ of mandate. The MPWMD filed a notice of cross-appeal on February 15, 2024. Cal Am is evaluating potential additional actions to seek to uphold LAFCO’s denial of the MPWMD’s application, including filing other challenges and/or making suitable presentations at a subsequent LAFCO rehearing.

MPWMD Condemnation Action

Separate from the proceedings related to the MPWMD’s application with LAFCO, by letter dated October 3, 2022, the MPWMD notified Cal Am of a decision to appraise the Monterey system assets and requested access to a number of Cal Am’s properties and documents to assist the MPWMD with such an appraisal. Cal Am responded by letter on October 24, 2022, denying the request for access, stating that the MPWMD does not have the right to appraise Cal Am’s system without LAFCO approval to become a retail water provider. On April 28, 2023, Cal Am rejected an offer by the MPWMD to purchase the Monterey system assets for $448.8 million. Over the written and oral objections of Cal Am, at a hearing held on October 10, 2023, the MPWMD adopted a resolution of necessity to authorize it to file an eminent domain lawsuit with respect to the Monterey system assets.

On December 15, 2023, the MPWMD filed a lawsuit against Cal Am in Monterey County Superior Court seeking to condemn the Monterey system assets. On February 26, 2024, Cal Am filed a motion requesting the Monterey County Superior Court dismiss the MPWMD’s eminent domain lawsuit seeking to condemn Cal Am’s Monterey system assets. Cal Am’s motion asserted that the MPWMD lacks legal authorization from both the California legislature and LAFCO to become a retail water provider and the lawsuit improperly seeks to effect a taking of property outside the boundaries of the MPWMD’s territory. Hearings on the motion were held on May 3, 2024, and August 23, 2024. On November 14, 2024, the court issued a final ruling denying Cal Am’s motion to dismiss. Cal Am filed its answer to the complaint on December 13, 2024. This matter remains pending.

While the Company cannot currently predict the outcome of this lawsuit, the Company believes that, given existing legal authorities and its other defenses, Cal Am should be able to defend itself successfully against the MPWMD’s eminent domain lawsuit.

Dunbar, West Virginia Class Action Litigation

On the evening of June 23, 2015, a 36-inch pre-stressed concrete transmission water main, installed in the early 1970s, failed. The water main is part of the West Relay pumping station located in the City of Dunbar, West Virginia and owned by West Virginia-American Water Company, the Company’s West Virginia subsidiary (“WVAWC”). The failure of the main caused water outages and low pressure for up to approximately 25,000 WVAWC customers. In the early morning hours of June 25, 2015, crews completed a repair, but that same day, the repair developed a leak. On June 26, 2015, a second repair was completed and service was restored that day to approximately 80% of the impacted customers, and to the remaining approximately 20% by the next morning. The second repair showed signs of leaking but the water main was usable until June 29, 2015, to allow tanks to refill. The system was reconfigured to maintain service to all but approximately 3,000 customers while a final repair was being completed safely on June 30, 2015. Water service was fully restored by July 1, 2015, to all customers affected by this event.

On June 2, 2017, a complaint captioned Jeffries, et al. v. West Virginia-American Water Company was filed in West Virginia Circuit Court in Kanawha County on behalf of an alleged class of residents and business owners who lost water service or pressure as a result of the Dunbar main break. The complaint alleges breach of contract by WVAWC for failure to supply water, violation of West Virginia law regarding the sufficiency of WVAWC’s facilities and negligence by WVAWC in the design, maintenance and operation of the water system. The Jeffries plaintiffs seek unspecified alleged damages on behalf of the class for lost profits, annoyance and inconvenience, and loss of use, as well as punitive damages for willful, reckless and wanton behavior in not addressing the risk of pipe failure and a large outage.

In February 2020, the Jeffries plaintiffs filed a motion seeking class certification on the issues of breach of contract and negligence, and to determine the applicability of punitive damages and a multiplier for those damages if imposed. In July 2020, the Circuit Court entered an order granting the Jeffries plaintiffs’ motion for certification of a class regarding certain liability issues but denying certification of a class to determine a punitive damages multiplier. Trial in this matter had been scheduled for January 2025.

On January 17, 2025, before trial commenced, the parties notified the Circuit Court that an agreement in principle to settle this litigation was reached among the parties. Under the terms of the agreement in principle and any subsequent proposed settlement agreement, WVAWC has not admitted, and will not admit, any fault or liability for any of the allegations made by the Jeffries plaintiffs. The proposed maximum pre-tax amount of the settlement is approximately $18 million, of which the Company currently estimates that approximately $5 million would be contributed by the Company and WVAWC, and the remainder would be contributed

by certain of the Company’s general liability insurance carriers. The actual total amount to be paid to claimants through this settlement will depend upon the claims submitted and approved through a claims process to be negotiated by the parties and approved by the Circuit Court. The parties will next negotiate and enter into a proposed settlement agreement based on the terms of the agreement in principle, and the proposed settlement agreement will be subject to preliminary and final approvals by the Circuit Court.

The final amount of the Company’s and WVAWC’s contributions to the settlement remains subject to uncertainty; however, the Company does not currently anticipate that Company’s maximum liability for the settlement will materially exceed $5 million. As a result, the Company has recorded a charge to earnings, net of insurance receivables, of $5.0 million ($3.9 million after-tax) in the fourth quarter of 2024. The Company intends to fund its and WVAWC’s contributions to the settlement through existing sources of liquidity, although no contribution by the Company or WVAWC will be required unless and until a proposed settlement agreement has been entered into and finally approved by the Circuit Court.

Chattanooga, Tennessee Class Action Litigation

On September 12, 2019, Tennessee-American Water Company, the Company’s Tennessee subsidiary (“TAWC”), experienced a leak in a 36-inch water transmission main, which caused service fluctuations or interruptions to TAWC customers and the issuance of a boil water notice. TAWC repaired the main by early morning on September 14, 2019, and restored full water service by the afternoon of September 15, 2019, with the boil water notice lifted for all customers on September 16, 2019.

On September 17, 2019, a complaint captioned Bruce, et al. v. American Water Works Company, Inc., et al. was filed in the Circuit Court of Hamilton County, Tennessee against TAWC, the Company and Service Company (collectively, the “Tennessee-American Water Defendants”), on behalf of a proposed class of individuals or entities who lost water service or suffered monetary losses as a result of the Chattanooga incident (the “Tennessee Plaintiffs”). The complaint alleged breach of contract and negligence against the Tennessee-American Water Defendants, as well as an equitable remedy of piercing the corporate veil. In the complaint as originally filed, the Tennessee Plaintiffs were seeking an award of unspecified alleged damages for wage losses, business and economic losses, out-of-pocket expenses, loss of use and enjoyment of property and annoyance and inconvenience, as well as punitive damages, attorneys’ fees and pre- and post-judgment interest. In September 2020, the court dismissed all of the Tennessee Plaintiffs’ claims in their complaint, except for the breach of contract claims against TAWC, which remain pending. In October 2020, TAWC answered the complaint, and the parties have been engaging in discovery. In January 2023, after hearing oral argument, the court issued an oral ruling denying the Tennessee Plaintiffs’ motion for class certification. In February 2023, the Tennessee Plaintiffs sought reconsideration of the ruling by the court, and any final ruling is appealable to the Tennessee Court of Appeals, as allowed under Tennessee law. In September 2023, the court upheld its prior ruling but gave the Tennessee Plaintiffs the option to file an amended class definition. In October 2023, the Tennessee Plaintiffs filed an amended class definition seeking certification of a business customer-only class. On June 14, 2024, the court issued its written order denying the Tennessee Plaintiffs’ amended class and incorporating its denial of certification of the original residential class. On June 21, 2024, the Tennessee Plaintiffs appealed both of the court’s orders denying class certification. This appeal remains pending.

The Company and TAWC believe that TAWC has valid, meritorious defenses to the claims raised in this class action complaint, and TAWC will continue to vigorously defend itself against these allegations.

Mountaineer Gas Company Main Break

During the afternoon of November 10, 2023, WVAWC was informed that an 8-inch ductile iron water main owned by WVAWC, located on the West Side of Charleston, West Virginia and originally installed in approximately 1989, experienced a leak. In the early morning hours of November 11, 2023, WVAWC crews successfully completed a repair to the water main. A precautionary boil water advisory was issued the same day to approximately 300 WVAWC customers and ultimately lifted on November 12, 2023.

On November 10, 2023, a break was reported in a low-pressure natural gas main located near the affected WVAWC water main, and an inflow of water into the natural gas main and associated delivery pipelines occurred. The natural gas main and pipelines are owned by Mountaineer Gas Company, a regulated natural gas distribution company serving over 220,000 customers in West Virginia (“Mountaineer Gas”). The resulting inflow of water into the natural gas main and related pipelines resulted in a loss of natural gas service to approximately 1,500 Mountaineer Gas customers, as well as water entering customer service lines and certain natural gas appliances owned or used by some of the affected Mountaineer Gas customers. Mountaineer Gas reported that restoration of natural gas service to all affected gas mains occurred on November 24, 2023. The timing, order and causation of both the WVAWC water main break and Mountaineer Gas’s main break are currently unknown and under investigation.

To date, a total of four pending lawsuits have been filed against Mountaineer Gas and WVAWC purportedly on behalf of customers in Charleston, West Virginia related to these incidents. On November 14, 2023, a complaint captioned Ruffin et al. v. Mountaineer Gas Company and West Virginia-American Water Company was filed in West Virginia Circuit Court in Kanawha

County on behalf of an alleged class of Mountaineer Gas residential and business customers and other households and businesses supplied with natural gas in Kanawha County, which lost natural gas service on November 10, 2023, as a result of these events. The complaint alleges, among other things, breach of contract by Mountaineer Gas, trespass by WVAWC, nuisance by WVAWC, violation of statutory obligations by Mountaineer Gas and WVAWC, and negligence by Mountaineer Gas and WVAWC. The complaint seeks class-wide damages against Mountaineer Gas and WVAWC for loss of use of natural gas, annoyance, inconvenience and lost profits, as well as punitive damages.

On November 15, 2023, a complaint captioned Toliver et al. v. West Virginia-American Water Company and Mountaineer Gas Company was filed in West Virginia Circuit Court in Kanawha County on behalf of an alleged class of all natural persons or entities who are citizens of the State of West Virginia and who are customers of WVAWC and/or Mountaineer Gas in the affected areas. The complaint alleges against Mountaineer Gas and WVAWC, among other things, negligence, nuisance, trespass and strict liability, as well as breach of contract against Mountaineer Gas. The complaint seeks class-wide damages against Mountaineer Gas and WVAWC for property damage, loss of use and enjoyment of property, annoyance and inconvenience and business losses, as well as punitive damages.

On November 16, 2023, a complaint captioned Dodson et al. v. West Virginia American Water and Mountaineer Gas Company was filed in West Virginia Circuit Court in Kanawha County on behalf of an alleged class of all West Virginia citizens living between Pennsylvania Avenue south of Washington Street, and Iowa Street, who are customers of Mountaineer Gas. The complaint alleges against Mountaineer Gas and WVAWC, among other things, negligence, nuisance, trespass, statutory code violations and unfair or deceptive business practices. The complaint seeks class-wide damages against Mountaineer Gas and WVAWC for property loss and damage, loss of use and enjoyment of property, mental and emotional distress, and aggravation and inconvenience, as well as punitive damages.

On January 4, 2024, a fourth complaint, captioned Thomas v. West Virginia-American Water Company and Mountaineer Gas Company, was filed in West Virginia Circuit Court in Kanawha County asserting similar allegations as those included in the Ruffin, Toliver and Dodson lawsuits, with the addition of counts alleging unjust enrichment and violations of the West Virginia Human Rights Act and the West Virginia Consumer Credit and Protection Act.

On November 17, 2023, the Ruffin plaintiff filed a motion to consolidate the class action lawsuits before a single judge in Kanawha County Circuit Court. On June 14, 2024, the judge in the Ruffin case partially granted the motion by transferring all of the four class action lawsuits to her court but deferring as premature consolidation of the cases.

On December 5, 2023, a complaint captioned Mountaineer Gas Company v. West Virginia-American Water Company was filed in West Virginia Circuit Court in Kanawha County seeking damages under theories of trespass, negligence and implied indemnity. The damages being sought related to the incident include, among other things, repair and response costs incurred by Mountaineer Gas and attorneys’ fees and expenses incurred by Mountaineer Gas. On December 14, 2023, Mountaineer Gas filed a motion with the Supreme Court of West Virginia to transfer this case to the West Virginia Business Court. On December 29, 2023, WVAWC filed a joinder in the motion to transfer the case. WVAWC has also filed a partial motion to dismiss this lawsuit. On March 6, 2024, the motion to transfer this complaint to the West Virginia Business Court was granted and trial and resolution judges were assigned. Mountaineer Gas voluntarily dismissed its implied indemnity count against WVAWC, rendering moot WVAWC’s partial motion to dismiss, and on May 31, 2024, WVAWC answered the complaint. The Business Court has set a trial date of October 7, 2025, for this matter.

On December 20, 2023, Mountaineer Gas filed answers to each of the first three class action lawsuits, which included cross-claims against WVAWC alleging that Mountaineer Gas is without fault for the claims and damages alleged in the lawsuits and WVAWC should be required to indemnify Mountaineer Gas for any damages and for attorneys’ fees and expenses incurred by Mountaineer Gas in the lawsuits. WVAWC has filed a partial motion to dismiss certain claims in the Ruffin, Toliver, Dodson and Thomas lawsuits and a motion to dismiss the cross-claims asserted against WVAWC therein by Mountaineer Gas. Mountaineer Gas subsequently voluntarily dismissed its cross-claims. On January 30, 2024, a motion was filed with the West Virginia Supreme Court on behalf of the Toliver plaintiff to refer the four class action complaints and the Mountaineer Gas complaint to the West Virginia Mass Litigation Panel. On February 7, 2024, WVAWC filed a motion joining in that referral request. On February 19, 2024, Mountaineer Gas filed a motion opposing the referral of the four class action complaints and the Mountaineer Gas complaint to the West Virginia Mass Litigation Panel. On May 31, 2024, the West Virginia Supreme Court denied the motion seeking referral. The Kanawha County Circuit Court has set a trial date of February 2, 2026, for the class action complaints.

On December 6, 2023, WVAWC initiated a process whereby Mountaineer Gas customers could file claims with WVAWC and seek payment from WVAWC of up to $2,000 in damages per affected household for the inconvenience arising from a loss of use of their appliances and documented out-of-pocket expenses as a result of the natural gas outage. In light of the diminishing number of new claims that had been filed, the claims process was concluded on March 8, 2024. As of December 31, 2024, a total of 594 Mountaineer Gas customers completed this claims process and each of those customers has been paid by WVAWC an average of approximately $1,500. In return, these customers were required to execute a partial release of liability in favor of WVAWC.

On November 16, 2023, the Public Service Commission of West Virginia (the “WVPSC”) issued an order initiating a general investigation into both the water main break and natural gas outages occurring in this incident to determine the cause or causes thereof, as well as breaks and outages generally throughout the systems of WVAWC and Mountaineer Gas and the utility practices of both utilities. Following a series of disagreements among the parties regarding the scope of discovery, the WVPSC closed the general investigation into both utilities and ordered a separate general investigation for each utility. The WVPSC focused the two general investigations away from the cause of the events and instead on the maintenance practices of each utility during and after the main breaks. On January 29, 2024, the Consumer Advocate Division of the WVPSC filed a motion to intervene in the WVAWC general investigation.

On April 24, 2024, the staff issued a final joint memorandum in the Mountaineer Gas general investigation stating its view that Mountaineer Gas responded appropriately, reasonably and according to Mountaineer Gas’s written procedures. The staff is making no recommendations for improvements to Mountaineer Gas and is recommending that the Mountaineer Gas general investigation be closed. On July 24, 2024, the staff issued a final joint memorandum in the WVAWC general investigation finding no indication of systematic failure by WVAWC and concluding WVAWC’s maintenance and operating procedures were adequate to ensure safe and reliable service, subject to the implementation by WVAWC of three recommended operational improvements. Both general investigations remain pending.

The Company and WVAWC believe that the causes of action and other claims asserted against WVAWC in the class action complaints and the lawsuit filed by Mountaineer Gas are without merit and that WVAWC has valid, meritorious defenses to such claims. WVAWC continues to defend itself vigorously in these litigation proceedings. Given the current stage of these proceedings and the general investigation, the Company and WVAWC are currently unable to predict the outcome of any of the proceedings described above.

PFAS Multi-District Litigation

Several of the Company’s utility subsidiaries are parties to a multi-district litigation (the “MDL”) lawsuit, which commenced on December 7, 2018, in U.S. District Court for the District of South Carolina, against manufacturers of certain PFAS for damages, contribution and reimbursement of costs incurred and continuing to be incurred to address the presence of such PFAS in public water supply systems owned and operated by these utility subsidiaries and throughout their service areas. Settlements with several defendants in the MDL proceeding have received final approval by the MDL court. In the third quarter of 2024, the Company timely submitted to the MDL court its Phase One claims forms under settlement agreements with defendants 3M Company, The Chemours Company, Corteva, Inc. and DuPont de Nemours, Inc.

On November 22, 2024, the MDL court granted final approval to settlements with defendants Tyco Fire Products LP and BASF Corporation. The Company’s utility subsidiaries have determined to remain parties to these class action settlements, and the Company has begun the process of perfecting its claims under each settlement within the time periods provided by the MDL court.

Cybersecurity Incident Class Action Lawsuits

Following the Company’s previously reported October 3, 2024, cybersecurity incident, nine putative class action lawsuits against parent company have been filed in the U.S. District Court for the District of New Jersey. All of the putative plaintiffs seek to certify a nationwide class and several of the plaintiffs seek to certify a state-specific subclass. The complaints allege primarily negligence, breach of implied contract, and claims of violations of federal and/or state consumer protection and data privacy law and seek damages and injunctive relief. On February 14, 2025, the court granted a motion to consolidate the nine current pending class actions. This consolidated matter remains pending. The Company believes that the causes of action and other claims asserted in the class action complaints are without merit and that the Company has valid, meritorious defenses to such claims, and the Company is defending itself vigorously.

General

Periodically, the Company is involved in other proceedings or litigation arising in the ordinary course of business. Other than those proceedings described in this Item 3—Legal Proceedings, the Company does not believe that the ultimate resolution of these matters will materially affect its financial position or results of operations. However, litigation and other proceedings are subject to many uncertainties, and the outcome of individual matters is not predictable with assurance. It is possible that some litigation and other proceedings could be decided unfavorably to the Company, and that any such unfavorable decisions could have a material adverse effect on its business, financial condition, results of operations and cash flows.

Not applicable.

PART II

Since April 23, 2008, the Company’s common stock has traded on the New York Stock Exchange (“NYSE”) under the symbol “AWK.” As of February 10, 2025, there were 194,947,313 shares of common stock outstanding held by approximately 1,922 record holders. Holders of the Company’s common stock are entitled to receive dividends when they are declared by its Board of Directors. See Note 9—Shareholders’ Equity in the Notes to Consolidated Financial Statements for additional information regarding the Company’s dividends.

In February 2015, the Board of Directors authorized an anti-dilutive stock repurchase program to mitigate the dilutive effect of shares issued through the Company’s dividend reinvestment, employee stock purchase and executive compensation activities. The program allows the Company to purchase up to 10 million shares of its outstanding common stock over an unrestricted period of time in the open market or through privately negotiated transactions. The program is conducted in accordance with Rule 10b-18 of the Exchange Act, and, to facilitate these repurchases, the Company enters into Rule 10b5-1 stock repurchase plans with a third-party broker, which allow the Company to repurchase shares of its common stock at times when it otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. Subject to applicable regulations, the Company may elect to amend or cancel the program or the stock repurchase parameters at its discretion to manage dilution.

From April 1, 2015, the date repurchases under the anti-dilutive stock repurchase program commenced, through December 31, 2024, the Company repurchased an aggregate of 4,860,000 shares of its common stock under the program, leaving an aggregate of 5,140,000 shares available for repurchase under this program. There were no repurchases of common stock in 2024.

The Company employs approximately 6,700 professionals who provide drinking water, wastewater and other related services to over 14 million people in 24 states. The Company’s primary business involves the ownership of utilities that provide water and wastewater services to residential, commercial, industrial, public authority, fire service and sale for resale customers, collectively presented as the “Regulated Businesses.” The Company’s utilities operate in 14 states in the United States, with 3.5 million active customers with services provided by its water and wastewater networks. Services provided by the Company’s utilities are subject to regulation by PUCs. The Company also operates other businesses not subject to economic regulation by state PUCs that provide water and wastewater services to the U.S. government on military installations, as well as municipalities, collectively presented throughout this Form 10-K within “Other.” See Item 1—Business for additional information.

Selected Financial Data

This selected financial data below should be read in conjunction with the Company’s Consolidated Financial Statements and related Notes in this Annual Report on Form 10-K as well as the remainder of this Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Financial Results

For the years ended December 31, 2024, 2023 and 2022, diluted earnings per share (GAAP) were $5.39, $4.90 and $4.51, respectively. Increased results were driven primarily by the implementation of new rates in the Regulated Businesses from capital and acquisition investments. Results also reflect increased production and employee-related costs, increased depreciation and higher financing costs used to fund the current capital investment plan. Results for 2024 and 2023 reflect the net favorable impact of warmer, drier weather compared to normal, estimated at $0.12 per share, and $0.13 per share, respectively. Results for 2024 include incremental interest income of $0.09 per share, resulting from the early 2024 amendment to the secured seller note from the sale of the former HOS business.

Growth Through Capital Investment in Infrastructure and Regulated Acquisitions

The Company continues to grow its businesses, with the substantial majority of its growth to be achieved in the Regulated Businesses through (i) continued capital investment in the Company’s infrastructure to provide safe, clean, reliable and affordable water and wastewater services to its customers, (ii) regulated acquisitions to expand the Company’s services to new customers and (iii) organic growth in existing systems. In 2024, the Company invested $3.3 billion, in the Regulated Businesses, as discussed below:

• $2.8 billion capital investment in the Regulated Businesses, for infrastructure improvements and replacements; and

• $417 million to fund acquisitions in the Regulated Businesses, which added approximately 69,500 customers during 2024. This includes the acquisitions by the Company’s Pennsylvania subsidiary of the wastewater collection and treatment system assets from the Butler Area Sewer Authority on October 29, 2024, for a cash purchase price of $230 million, which added approximately 15,000 customer connections, and by the Company’s Illinois subsidiary of a wastewater treatment plant and related assets from Granite City on March 11, 2024, for a cash purchase price of $86 million, which added approximately 26,000 wastewater customers, including 15,500 customers indirectly in surrounding communities.

• Approximately 19,400 new customers were added t

The Company is exposed to market risk associated with changes in commodity prices, equity prices and interest rates. The Company is exposed to risks from changes in interest rates as a result of its issuance of variable and fixed rate debt and commercial paper. The Company manages its interest rate exposure by limiting its variable rate exposure and by monitoring the effects of market changes in interest rates. The Company also has the ability to enter into financial derivative instruments, which could include instruments such as, but not limited to, interest rate swaps, forward starting swaps and U.S. Treasury lock agreements to manage and mitigate interest rate risk exposure. As of December 31, 2024, a hypothetical 1% increase in average interest rates applied to the Company’s short-term borrowing balances throughout 2024 would result in an increased annual interest expense of approximately $2 million.

As of December 31, 2024, the Company had eight treasury lock agreements, each with a term of 10 years or 30 years, with notional amounts totaling $355 million, to reduce interest rate exposure on debt expected to be issued in 2025. These treasury lock agreements terminate in June 2025 and December 2025 and have an average fixed rate of 4.03%. When entering into treasury locks, the Company is subject to market risk with respect to changes in the underlying benchmark interest rate that impacts the fair value of the treasury locks. The Company manages market risk by matching the terms of the treasury locks with the critical terms of the expected debt issuance. The fair value of the treasury locks at December 31, 2024, was in a gain position of $24 million. A hypothetical 1% favorable change in interest rates would result in an increase in the fair value of the treasury locks to a gain position of approximately $60 million at December 31, 2024.

The Company’s risks associated with price increases for chemicals, electricity and other commodities are reduced through contractual arrangements and the expected ability to recover price increases through rates, in the next general rate case proceeding or other regulatory mechanism, as authorized by each regulatory jurisdiction. Non-performance by these commodity suppliers could have a material adverse impact on the Company’s results of operations, financial position and cash flows.

The market price of the Company’s common stock may experience fluctuations, which may be unrelated to its operating performance. In particular, the Company’s stock price may be affected by general market movements as well as developments specifically related to the water and wastewater industry. These could include, among other things, interest rate movements, quarterly variations or changes in financial estimates by securities analysts and governmental or regulatory actions. This volatility may make it difficult for the Company to access the capital markets in the future through additional offerings of its common stock or other equity securities, regardless of its financial performance, and such difficulty may preclude the Company from being able to take advantage of certain business opportunities or meet business obligations.

The Company is exposed to credit risk through its water, wastewater and related services. The Company’s Regulated Businesses serve residential, commercial, industrial and other customers, while the businesses within Other engage in business activities with government entities and other customers. The Company’s primary credit risk is exposure to customer default on contractual obligations and the associated loss that may be incurred due to the non-payment of customer accounts receivable balances. The Company’s credit risk is managed through established credit and collection policies which are in compliance with applicable regulatory requirements and involve monitoring of customer exposure and the use of credit risk mitigation measures such as letters of credit or prepayment arrangements. The Company’s credit portfolio is diversified with no significant customer or industry concentrations. In addition, the Regulated Businesses are generally able to recover all prudently incurred costs including uncollectible customer accounts receivable expenses and collection costs through rates.

The Company’s retirement trust assets are exposed to the market prices of debt and equity securities. Changes to the retirement trust asset values can impact the Company’s pension and other benefits expense, funded status and future minimum funding requirements. Changes in interest rates can impact retirement liabilities. The Company aims to reduce risk through asset diversification and by investing in long duration fixed-income securities that have a duration similar to that of its pension liabilities, seeking to hedge some of the interest rate sensitivity of its liabilities. That way, if interest rates fall and liabilities increase, the Company expects that the fixed-income assets in its retirement trust will also increase in value. The Company also expects its risk to be reduced through its ability to recover pension and other benefit costs through rates.

The Company is also exposed to a potential national economic recession or deterioration in local economic conditions in the markets in which it operates. The credit quality of the Company’s customer accounts receivable is dependent on the economy and the ability of its customers to manage through unfavorable economic cycles and other market changes. In addition, there can be no assurances that regulators will grant sufficient rate authorizations. Therefore, the Company’s ability to fully recover operating expense, recover its investment and provide an appropriate return on invested capital made in the Regulated Businesses may be adversely impacted.

We have audited the accompanying consolidated balance sheets of American Water Works Company, Inc. and its subsidiaries (the “Company”) as of December 31, 2024 and 2023, and the related consolidated statements of operations, of comprehensive income, of changes in shareholders’ equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023**,** and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the

Disclosure Controls and Procedures

The Company, under the supervision and with the participation of its management, including its Chief Executive Officer and its Chief Financial Officer, conducted an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as such term is defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act as of the end of the period covered by this report.

Based on that evaluation, the Company’s Chief Executive Officer and its Chief Financial Officer have concluded that, as of December 31, 2024, the Company’s disclosure controls and procedures were effective at a reasonable level of assurance. The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objective.

Management’s Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. The Company’s internal control over financial reporting is a process designed by or under the supervision of the Company’s Chief Executive Officer and its Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect its transactions and dispositions of its assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with GAAP, and that the Company’s receipts and expenditures are being made only in accordance with authorizations of its management and its directors, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of its assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s management, including the Company’s Chief Executive Officer and its Chief Financial Officer, assessed the effectiveness of its internal control over financial reporting, as of December 31, 2024, using the criteria described in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Based on the Company’s evaluation under the framework in Internal Control—Integrated Framework (2013), its management concluded that its internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2024, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report appearing in Item 8—Financial Statements and Supplementary Data of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

The Company concluded that there have been no changes in internal control over financial reporting that occurred during its last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Chief Executive Officer Succession

On February 19, 2025, reflecting the Company’s existing and ongoing executive development and succession planning activities by management and the Board of Directors, Ms. Hardwick, the Company’s Chief Executive Officer and a director, notified Karl F. Kurz, Board Chair, of her decision to retire as the Company’s Chief Executive Officer and principal executive officer, effective as of the conclusion of the Company’s 2025 Annual Meeting of Shareholders (the “2025 Annual Meeting”). In her notice, Ms. Hardwick also indicated her decision not to stand for re-election to the Board of Directors at the 2025 Annual Meeting. On February 19, 2025, the Board of Directors accepted Ms. Hardwick’s notice and, upon the recommendation of the Nominating Committee, determined that she would not stand for re-election to the Board of Directors at the 2025 Annual Meeting. Ms. Hardwick’s decision not to stand for re-election to the Board of Directors was not as a result of any disagreement with the Company or the Board of Directors on any matter relating to the Company’s operations, policies or practices.

On February 19, 2025, to provide for the orderly succession of Ms. Hardwick’s roles, the Board of Directors designated Mr. Griffith, the Company’s President, to serve as the Company’s President and Chief Executive Officer and as principal executive officer, effective as of the conclusion of the 2025 Annual Meeting, to hold office until the Company’s 2026 Annual Meeting of Shareholders (the “2026 Annual Meeting”) and until his successor has been elected and qualified, or until his earlier death, resignation or removal. Upon the recommendation of the Nominating Committee, the Board of Directors also nominated Mr. Griffith for election to the Board of Directors at the 2025 Annual Meeting, and he will be included among the director nominees of the Board of Directors to be named in the Company’s 2025 Proxy Statement. If elected to the Board of Directors by the shareholders of the Company, Mr. Griffith would serve until the Company’s 2026 Annual Meeting and until his successor has been elected and qualified, or until his earlier death, resignation or removal, and would not serve on any committee of the Board of Directors. See Item 1—Business—Information About Our Executive Officers, for more information about Mr. Griffith’s business experience.

Other than existing compensatory arrangements between Mr. Griffith and the Company as described in the Company’s 2024 Proxy Statement, in connection with his succession: (i) there are no arrangements or understandings between Mr. Griffith and any other person pursuant to which Mr. Griffith was designated or nominated to serve in his new roles, (ii) no material plan, contract or arrangement has been entered into with Mr. Griffith, and no such plan, contract or arrangement with Mr. Griffith has been materially amended, and (iii) no grant of any award to Mr. Griffith or modification of an existing award has been made. Mr. Griffith does not have any family relationship with any director or other executive officer of the Company, or any person nominated or chosen by the Company to become a director or executive officer, and does not have any direct or indirect material interest in any transaction in which the Company is or is to be a participant and which would require reporting under Item 404(a) of Regulation S-K.

In connection with Ms. Hardwick’s retirement, the ED&CC recommended, based on the advice of its independent compensation consultant, and the independent members of the Board of Directors approved, in addition to Ms. Hardwick’s customary executive compensation for 2025 (which was consistent with her executive compensation for 2024), a discretionary cash payment to Ms. Hardwick of $800,000, less all applicable withholdings and deductions, in recognition of her outstanding service and performance in the role as Chief Executive Officer.

Board of Directors Committee Changes

As part of its annual 2025 committee review process and to appropriately distribute director responsibilities, on February 19, 2025, the Board of Directors, upon the recommendation of the Nominating Committee, appointed director Stuart M. McGuigan to serve on the ED&CC and the SETO Committee, and determined that director Patricia L. Kampling will no longer serve on the SETO Committee, each of which actions took effect immediately.
