Operating revenues were earned from the following sources:

Water Supplies and Contracts

Our New Jersey and Delaware water supply systems are physically separate and are not interconnected. In New Jersey, the Pinelands System is not interconnected with the Middlesex System. We believe we have adequate sources of water supply to meet the current service requirements of our present customers in New Jersey and Delaware.

Middlesex System

Our Middlesex System produced approximately 14.3 billion gallons in 2024 from:

The Middlesex System’s distribution storage facilities are used to supply water to customers at times of peak demand, outages and emergencies.

The principal source of surface water for the Middlesex System is the Delaware & Raritan Canal, which is owned by the State of New Jersey and operated by the New Jersey Water Supply Authority (NJWSA). Middlesex is under contract with the NJWSA, which expires November 30, 2048, and provides for average purchases of 27.0 mgd, with a peak up to 47.0 mgd, of untreated water from the Delaware & Raritan Canal, augmented by the Round Valley/Spruce Run Reservoir System. The untreated surface water is pumped to, and treated at, the CJO Plant.

Tidewater System

Our Tidewater System, together with our wholly-owned subsidiary, Southern Shores, produced approximately 3.3 billion gallons in 2024, primarily from 172 wells. Tidewater expects to submit applications to Delaware regulatory authorities for the approval of additional wells as growth, customer demand and water quality warrant. Tidewater augments its water production with annual purchases of up to 75.0 million gallons of treated water from the City of Dover, Delaware. Tidewater does not have a central water treatment facility for the over 480 separate communities it serves. As the number has grown, many of Tidewater’s individual systems have been interconnected, forming several regional systems that are served by multiple water treatment facilities owned by Tidewater. 

Pinelands Water System

Water supply to our Pinelands Water System is derived from four wells which produced approximately 141.1 million gallons in 2024. The aggregate pumping capacity of the four wells is 2.2 mgd.

Wastewater Facilities

Pinelands Wastewater System

The Pinelands Wastewater System discharges into the South Branch of the Rancocas Creek through a wastewater treatment plant that provides clarification, sedimentation, filtration and disinfection. The total capacity of the plant is 0.5 mgd, and the system treated approximately 92.6 million gallons in 2024.

Human Capital Management

The Company strives to attract and retain employees by offering competitive compensation and benefits along with career development and training opportunities in a safe, supportive and inclusive work environment. Our mission, our business philosophy and the manner in which we deliver value for our customers, our shareholders and our employees is inherent in what we, as an enterprise, profess to be our core values of Respect, Integrity, Growth, Honesty and Teamwork. Our employees’ success is a key element of the Company’s success.

Workforce

As of December 31, 2024, the Company had 360 employees. None of our employees is subject to a collective bargaining agreement. We believe our employee relations are positive.

Employee Compensation and Benefits

We offer comprehensive competitive employee compensation and benefit programs consistent with job functions, skill levels, experience, knowledge and geographic location. These programs are periodically independently evaluated by a nationally recognized consulting firm to gauge effectiveness and are benchmarked against industry peers and the overall markets in which we operate our businesses. Compensation increases and incentive compensation are based on merit, which is communicated to employees and documented in our bi-annual performance evaluation process. Benefits include a variety of programs to enhance employee overall physical, mental and financial health and well-being, including healthcare insurance, employer funded retirement savings plans, life insurance, disability insurance, accident insurance, tuition reimbursement, flu shots, wellness newsletters and webinars, flexible hybrid office and remote work capabilities, incentive programs for achieving fitness milestones, financial counseling, elder care assistance, substance abuse support and more.

Safety

The Company has implemented safety programs and management practices designed to promote a culture of safety to protect its employees. This includes required trainings for employees, as well as specific qualifications and certifications for certain operational employees. All employees have been empowered to report, and immediately stop work which, in their personal judgement, is unsafe or is not consistent with our safety policies and procedures. They can take this action without fear of reprisal.

Employee Development and Training

The Company employs various training and other educational programs and has developed company-wide and project-specific training and educational programs, including tuition assistance for full-time employees enrolled in pre-approved undergraduate or graduate courses or professional licensing courses. All employees receive training to identify and report operational and financial risks, as well as risks to Company brand and reputation, which fosters a personal culture of accountability and reinforces our commitment to a safe and sustainable workplace.

The Company is focused on recruitment and/or development of both external and internal candidates so that all prospective and current employees are provided an opportunity to advance their careers. Statements on belonging and inclusion can be found on our website and are not part of this Annual Report on Form 10-K.

Competition

Our business in our franchised service areas is substantially free from direct competition for growth with other public utilities, municipalities and other entities. However, our ability to provide contract wholesale water supply and operations and maintenance services that are not under the jurisdiction of a state public utility commission is subject to competition from other public utilities, municipalities and other entities. Although Tidewater has been granted exclusive franchises for its existing community water systems, the ability to expand service areas can be affected by the Delaware Public Service Commission (DEPSC) awarding franchises to other regulated water utilities with whom we compete for such franchises and for projects.

Regulation

Our rates charged to customers for utility services, the quality of the services we provide and certain other matters are regulated by the state public utility commissions in the states where we operate, including the NJBPU and the DEPSC (collectively, the Public Utility Commissions).

Our USA, USA-PA and White Marsh subsidiaries are not regulated public utilities as related to rates and service quality. However, they are subject to federal and state environmental regulations with respect to water quality and wastewater effluent quality to the extent such services are provided.

We are subject to environmental and water quality regulation by the following regulatory agencies (collectively, the Government Environmental Regulatory Agencies):

In addition, our issuances of equity securities are subject to the prior approval of the NJBPU and require registration with the United States Securities and Exchange Commission. Our issuances of long-term debt securities are subject to the prior approval of the respective state Public Utility Commissions.

Regulation of Rates and Services

For regulated rate setting purposes, we account separately for our regulated utility operations to facilitate independent rate setting by the applicable Public Utility Commissions.

In determining our regulated utility rates, the respective Public Utility Commissions consider the revenue, expenses and utility infrastructure used and useful in providing service to the public. Rate determinations by the respective Public Utility Commissions do not guarantee achievement by our regulated utility companies of specific rates of return for our regulated utility operations. Thus, we may not achieve the rates of return authorized by the Public Utility Commissions. In addition, there can be no assurance that any future rate increases will be granted or, if granted, that they will be in the amounts requested.

Middlesex Rate Matters

The approval by the NJBPU in February 2024 of the negotiated settlement of the Middlesex 2023 base rate case is expected to increase annual operating revenues by $15.4 million, effective March 1, 2024. The approved tariff rates were designed to recover increased operating costs as well as a return on invested capital of $563.1 million, based on an authorized return on common equity of 9.6%. Middlesex has made capital infrastructure investments to ensure prudent upgrade and replacement of its utility assets to support continued regulatory compliance, resilience and overall quality of service. In August 2023, Middlesex and 3M Company (3M) executed a settlement agreement (Settlement Agreement) to resolve a lawsuit Middlesex previously initiated claiming 3M introduced Perfluoroalkyl Substances (PFAS) into the Company’s water supply for its Park Avenue Wellfield Treatment Plant (Park Avenue Plant). The rate case settlement provided that the net proceeds from the 3M Settlement Agreement were to be used to mitigate the increase in customer rates and reimburse Middlesex for previously incurred costs for the construction of the Park Avenue Plant PFAS treatment upgrades, including depreciation and carrying costs. This resulted in the reclassification of $48.3 million from Regulatory Liabilities to Contributions in Aid of Construction from the December 31, 2023 balance sheet. In 2024, the Company also recognized the recovery of $0.9 million for depreciation and $4.1 million for carrying costs associated with the Park Avenue Plant PFAS treatment upgrades, as well as the recovery of $2.6 million of previously incurred operating treatment costs while the Park Avenue Plant PFAS treatment upgrades were in process.

The Middlesex Lead Service Line Replacement (LSLR) Plan, which was approved by the NJBPU in January 2024, has commenced and Middlesex is currently recovering $1.2 million of costs for replacing customer-owned lead service lines incurred through June 2024, which are being recovered between September 2024 and February 2025. Costs of $0.6 million for replacing customer-owned lead service lines incurred between July 2024 through December 2024 will be recovered beginning in March 2025 through August 2025. The LSLR surcharge is required to be reset every six months over the life of the LSLR Plan. Cost recovery for replacing Company-owned lead service lines are recoverable through traditional rate making in connection with general rate case filings.

In October 2023, the NJBPU approved Middlesex’s petition for a Distribution System Improvement Charge (DSIC) Foundation Filing, which is a prerequisite to implementing a DSIC rate that allows water utilities to recover investments in, and generate a return on, qualifying capital improvements to their water distribution system made between base rate proceedings. Middlesex is authorized to recover DSIC revenues up to five percent (5%) of total revenues established in Middlesex’s 2021 base rate proceeding, or approximately $5.5 million. Semi-annually, beginning in April 2024, the Company must file for a change in its DSIC rate seeking recovery for DSIC-eligible investments made during the period. DSIC rates remain in effect until Middlesex’s next base rate case increase subsequent to the March 1, 2024 increase. Under the terms of the Foundational Filing, the Company is required to file a base rate petition before November 2026.

In May 2024, the NJBPU approved a DSIC rate, effective May 26, 2024, that is expected to result in $0.5 million of annual revenue. In November 2024, the NJBPU approved a DSIC rate, effective November 26, 2024, that is expected to result in an additional $0.6 million of annual revenue. Middlesex expects to file for an additional DSIC rate increase in April 2025.

In February 2025, the NJBPU approved Middlesex’s petition to reset its Purchased Water Adjustment Clause (PWAC) tariff rate to recover additional annual costs of $0.5 million, primarily for the purchase of treated water from a non-affiliated water utility regulated by the NJBPU. A PWAC is a rate mechanism that allows for the

recovery of increased purchased water costs between base rate case filings. The PWAC is reset to zero once those increased costs are included in base rates. The new PWAC rate will be effective March 1, 2025.

Tidewater Rate Matters

In September 2024, the DEPSC approved Tidewater’s petition to recover up to $2.1 million of costs associated with Tidewater’s obligation to identify and inventory lead service lines throughout Tidewater’s service area, as required by federal law and Delaware regulations. Recovery of these costs began February 1, 2025 and is expected to continue through January 2028. Through December 31, 2024, Tidewater has spent $1.8 million, which is included in Regulatory Assets.

In August 2024, Tidewater filed an application with the DEPSC to increase its general rates for water service. In the application, Tidewater seeks an overall increase in annual operating revenue of $10.3 million or 25.66% over current revenue. The request for rate increases will allow Tidewater to recover prudently incurred investments made in the last ten years to support continued regulatory compliance, enhanced water quality, service reliability, security and resiliency of the water utility infrastructure assets. Effective October 30, 2024, Tidewater received approval of the DEPSC to suspend its DSIC rate and implement an interim rate increase, which is expected to result in approximately $2.5 million of annual revenues, subject to refund pending the outcome of the rate case application.

In February 2025, Tidewater and the Town of Ocean View, Delaware’s (Ocean View) joint application of Tidewater’s purchase of all of the rights, title, and interest in the water utility assets of Ocean View for $4.6 million was approved by the DEPSC. Ocean View serves approximately 900 customers in Sussex County, Delaware. Tidewater currently provides water service to most residents of Ocean View other that the 900 customers currently served by Ocean View. Closing on this purchase is expected by April 2025.

Southern Shores Rate Matters

Southern Shores provides water service to a 2,200 unit condominium community in Sussex County, Delaware under a DEPSC-approved agreement expiring December 31, 2029 .  Under the agreement, rates are increased when there are unanticipated capital expenditures or regulatory related changes in operating expenses exceed certain thresholds. In 2024, capital expenditures did exceed the established threshold. In addition, rates are increased annually by the lesser of the regional Consumer Price Index or 3%. Effective January 1, 2025, Southern Shores rates were increased $0.1 million or 6.51%.

Regulatory Service Matters

Twin Lakes Utilities, Inc. (Twin Lakes) – Twin Lakes provides water services to approximately 115 residential customers in Shohola, Pennsylvania. In January 2021, the Pennsylvania Public Utility Commission (PAPUC) appointed a large Pennsylvania based investor-owned utility as the receiver (the Receiver Utility) of the Twin Lakes system. In November 2021, the PAPUC issued an Order ordering the Receiver Utility to acquire the Twin Lakes water system and for Middlesex, the parent company of Twin Lakes, to submit $1.7 million into an escrow account within 30 days. In January 2025, the United States Court of Appeals for the Third Circuit (Third Circuit Court) upheld the PAPUC Order. Following the Third Circuit Court’s decision, Middlesex will not pursue further litigation in the federal courts and intends to submit the required escrow payment to complete the Receiver Utility’s acquisition of the Twin Lakes system. The estimated loss recorded by the Company related to this matter, and the financial results, total assets and financial obligations of Twin Lakes are not material to Middlesex. 

Water and Wastewater Quality and Environmental Regulations

Government environmental regulatory agencies regulate our operations in New Jersey and Delaware with respect to water supply, treatment and distribution systems and the quality of the water.  They also regulate our operations with respect to wastewater collection, treatment and disposal.

Regulations relating to water quality require us to perform tests to ensure our water meets state and federal quality requirements. We participate in industry-related research to identify technologies that may reduce the level of

organic, inorganic and synthetic compounds found in water. The cost to water utilities to comply with any proposed water quality standards depends in part on the limits set in the regulations and on the method selected to treat the water to the required standards. We regularly test our water to determine compliance with government environmental regulatory agencies’ water quality standards.

In April 2024, the USEPA finalized drinking water regulations for PFAS, establishing maximum contaminant levels (MCLs) for three PFAS compounds (Regulated PFAS) that are lower than the current New Jersey Department of Environmental Protection MCLs adhered to by the Company. Under the new USEPA regulations effective April 2024, water systems must monitor for Regulated PFAS and have three years to complete initial monitoring (by April 2027), followed by ongoing compliance monitoring. Water systems must also provide the public with information on the levels of Regulated PFAS in their drinking water beginning in 2027. Water systems have five years (by April 2029) to implement solutions that reduce Regulated PFAS if monitoring shows that drinking water levels exceed these MCLs.

Beginning in April 2029, water systems that have Regulated PFAS in drinking water which exceeds one or more of these MCLs must take action to reduce levels of these PFAS compounds in their drinking water and must provide notification to the public of the violation.

In anticipation of these new USEPA standards, in 2023, the Company began implementing its strategy to meet these lower MCLs for Regulated PFAS and is currently performing preliminary engineering studies to ensure that effective PFAS treatment approaches are implemented.

We treat the groundwater supplies in our Middlesex System with chlorination for primary disinfection purposes and use air stripping for removal of volatile organic compounds.

Surface water treatment in our Middlesex System is by conventional treatment; coagulation, sedimentation and filtration. The treatment process includes pH adjustment, ozone and chlorination for disinfection, and corrosion control for the distribution system.

Treatment of groundwater in our Tidewater System is by chlorination for disinfection purposes and, in some cases, pH adjustment and filtration for nitrate and iron removal and granular activated carbon filtration for organics removal. Chloramination is used for final disinfection at Southern Shores.

Treatment of groundwater in the Pinelands Water System (primary disinfection only) is performed at individual well sites.

Treatment of wastewater in the Pinelands Wastewater System includes the use of rotating biological contactors.  

The NJDEP and DEDPH monitor our activities and review the results of water quality tests that are performed for adherence to applicable regulations. Other applicable regulations include the Lead, Copper and Lead Service Line Rules, the Federal Surface Water Treatment Rule and the Federal Total Coliform Rule and regulations for maximum contaminant levels established for various volatile organic compounds.

The Company must comply with various environmental laws and regulations promulgated by the USEPA, NJDEP and other governmental agencies, including the Toxic Catastrophe Prevention Act, the Spill Prevention, Control, and Countermeasure Rule and the Discharge Prevention Program of the New Jersey Spill Compensation and Control Act.

Seasonality

Customer demand for our water during the warmer months is generally greater than other times of the year due primarily to additional consumption of water in connection with irrigation systems, swimming pools, cooling systems and other outside water use. Throughout the year, and particularly during typically warmer months, demand may vary with temperature and rainfall timing and overall levels. In the event that temperatures during the typically warmer months are cooler than normal, or if there is more rainfall than normal, the customer demand for our water may decrease and therefore, adversely affect our revenues.

Operational Risks

Weather conditions and overuse of underground aquifers may interfere with our sources of water, demand for water services and our ability to supply water to customers.

Our ability to meet current and future water demands of our customers depends on the availability of an adequate supply of water. Unexpected conditions may interfere with our water supply sources. Drought and overuse of underground aquifers may limit the availability of ground and/or surface water. Freezing weather may also contribute to water transmission interruptions caused by water main breakage. Any interruption in our water supply could cause a reduction in our revenue and profitability. These factors may adversely affect our ability to supply water in sufficient quantities to our customers. Governmental drought restrictions, heightened levels of rainfall and temperatures during the typically warmer months that are cooler than normal may result in decreased customer demand for water services and can adversely affect our revenue and earnings.

Our water sources or water service provided to customers may become contaminated by naturally-occurring or man-made compounds and events. This may cause disruption in services and impose operational and regulatory enforcement costs upon us to restore the water to required levels of quality as well as may damage our reputation and cause private litigation claims against us.

Our sources of water or water in our distribution systems have in the past and in the future may again become contaminated by naturally-occurring or man-made compounds or other contaminants. In the event that any portion of our water supply sources or water distribution systems is contaminated, we may need to interrupt service to our customers until we are able to remediate the contamination or substitute the flow of water from an uncontaminated water source through existing interconnections with other water purveyors or through our transmission and distribution systems, where possible. We may also incur significant costs in treating any contaminated water, or remediating the effects on our treatment and distribution systems, through the use of our current treatment facilities, or development of new treatment methods. Our inability to substitute water supply from an uncontaminated water source, or to adequately treat the contaminated water supply in a cost-effective manner, may reduce our revenues or increase our expenses and make us less profitable.

We may be unable to recover costs associated with treating water supplies through rates or, recovery of these costs may not occur in a timely manner. In addition, we could be subject to claims for damages arising from government enforcement actions or legal actions arising out of interruption of service or actual or perceived human exposure to contaminants in our drinking water and water supplies. Such costs could adversely affect our financial results.

Contamination of the water supply or the water service provided to our customers could result in substantial injury or damage to our customers, employees or others and we could be exposed to substantial claims and litigation, which are inherently subject to uncertainties and are potentially subject to unfavorable regulatory and/or legal actions. Previously, claims have been brought against us alleging our customers received contaminated water. Negative impacts to our profitability and/or our reputation may occur even if we are not responsible for the contamination or the consequences arising out of human exposure to contamination or hazardous substances in the water supplies. Pending or future claims against us could have a material adverse impact on our financial condition, results of operations and cash flows.

The necessity for ongoing physical and technological security has resulted, and may continue to result, in increased operating costs.

Because of physical and technological threats to the health and security of the United States of America, we employ physical and technological security measures to guard against such threats and have implemented procedures to review and modify security measures. We provide ongoing training and communications to our employees about threats to our water supply, our assets and related systems and our employees’ personal safety. We have incurred, and will continue to incur, costs for security measures in efforts to protect against such risks.

Climate variability may cause weather volatility in the future, which may impact water usage and related revenue or, may require additional expenditures to reduce risk associated with any increasing storm, flood, drought or other weather occurrences.

Increased climate variability may cause increased precipitation and flooding, increased frequency and severity of storms and droughts and other weather events, any of which may result in degradation of water quality, decreases in available water supply, changes in water usage patterns and disruptions in service. Because of the uncertainty of weather volatility related to climate variability, we cannot predict its potential impact on our financial condition, results of operations, cash flows and liquidity.  Although some or all potential expenditures and costs with respect to our regulated businesses could be recovered through rates we charge to our customers, there can be no assurance that the NJBPU or the DEPSC would authorize recovery of such costs, in whole or in part.

Regulatory Risks

Our revenue and earnings depend on the rates we charge our customers. We cannot raise utility rates in our regulated businesses without petitioning and receiving approval from the appropriate Public Utility Commissions. If these agencies modify, delay or deny our petition, our revenues will not increase and our earnings will decline unless we are able to reduce costs without degrading service quality.

The NJBPU regulates our public utility companies in New Jersey with respect to rates and charges for service, classification of accounts, awards of new service territory, acquisitions, financings and other matters. That means, for example, that we cannot raise the utility rates we charge to our customers without first petitioning the NJBPU for approval and navigating a lengthy administrative process. Similarly, the DEPSC regulates our public utility companies in Delaware. We cannot provide assurance as to when we will request approval for any such matter, nor can we predict whether these Public Utility Commissions will approve, deny or reduce the amount of such requests.

Certain costs are not completely within our control. The failure to obtain any rate increase would prevent us from increasing our revenues and, unless we are able to reduce costs without degrading service quality, would result in reduced earnings.

We are subject to environmental laws and regulations, including water quality and wastewater effluent quality regulations, as well as other state and local regulations. Compliance with those laws and regulations requires us to incur costs and we are subject to fines or other sanctions for non-compliance.

Government environmental regulatory agencies regulate our operations in New Jersey and Delaware with respect to water supply, treatment and distribution systems and the quality of water. Government environmental regulatory agencies also regulate our operations in New Jersey and Delaware with respect to wastewater collection, treatment and disposal.

Government environmental regulatory agencies’ regulations relating to water quality require us to perform additional testing to ensure our water meets state and federal water quality requirements. We are subject to USEPA regulations under the Federal Safe Drinking Water Act and under the Federal Clean Water Act regarding wastewater services. Regulations under the Safe Drinking Water Act include the Lead and Copper Rule, the maximum contaminant levels established for various volatile organic compounds, the Federal Surface Water Treatment Rule and the Total Coliform Rule. There are also similar NJDEP regulations for our New Jersey water systems. The NJDEP and DEDPH monitor our activities and review the results of water quality tests we perform for adherence to applicable regulations. In addition, Government Environmental Regulatory Agencies are continually reviewing regulations governing the limits of certain organic compounds found in the water as byproducts of treatment.

We are also subject to regulations related to fire protection services in New Jersey and Delaware. In New Jersey there is no state-wide fire protection regulatory agency. However, New Jersey regulations exist as to the size of piping required regarding the provision of fire protection services. In Delaware, fire protection is regulated statewide by the Office of State Fire Marshal.

The cost of compliance with the water and wastewater effluent quality standards depends in part on the limits set in the regulations and on the methods selected to comply with these standards. If new or more restrictive standards are imposed, the cost of compliance could increase and therefore, have an adverse impact on our revenues and results of operations if we cannot recover those costs through the rates we charge our customers. The cost of compliance with fire protection requirements could also increase and make us less profitable if we cannot recover those costs through our rates charged to our customers.

The Company  must comply with various environmental laws and regulations promulgated by the USEPA, NJDEP and other governmental agencies, including the Toxic Catastrophe Prevention Act, the Spill Prevention, Control, and Countermeasure Rule and the Discharge Prevention Program of the New Jersey Spill Compensation and Control Act. If we fail to comply with environmental or other laws and regulations to which our business is subject, we could be fined or subject to other sanctions, which could adversely impact our business or results of operations.

Financial Risks

We depend upon our ability to raise money in the capital markets to finance some of the costs of complying with laws and regulations, including environmental laws and regulations or to pay for some of the costs of improvements to or the expansion of our utility system assets. Our regulated utility companies cannot issue debt or equity securities without prior regulatory approval.

We require financing from external sources to fund the ongoing capital program for the improvement in our utility system assets and for planned expansion of those systems. We expect to spend approximately $387 million for capital projects through 2027. We must obtain prior approval from our economic regulators to sell debt or equity securities to raise capital for these projects. If sufficient capital is not available, or the cost of capital is too high, or if the regulatory authorities deny our petition to sell debt or equity securities, we may not be able to meet the costs of complying with environmental laws and regulations or the costs of improving and expanding our utility system assets to the level we believe operationally prudent. This may result in the imposition of fines from environmental regulators or restrictions on our operations which could curtail our ability to upgrade or replace utility system assets and have a material adverse effect on our financial condition and results of operations.

We face competition from other utilities and service providers which might hinder our growth opportunities and mitigate our future profitability.

We face risks of competition from other utilities or other entities authorized by federal, state or local agencies to expand rate-regulated or contracted utility services. Once a state utility regulator grants a franchise to a public utility to serve a specific territory, that utility effectively has an exclusive right to service that territory. Although a new franchise offers some protection against competitors, the pursuit of franchises is often competitive, particularly in Delaware, where new franchises may be awarded to utilities based upon competitive negotiation. Competing entities have challenged, and may challenge in the future, our applications for new franchises. Also, third parties entering into agreements to operate municipal utility systems may adversely affect the management of our long-term agreements to supply water or wastewater services on a contract basis to those municipalities, which could adversely affect our financial results.

We have short-term and long-term contractual obligations for water, wastewater and storm water system operation and maintenance under which we may incur costs in excess of payments received.

USA-PA and USA operate and maintain water and wastewater systems for three New Jersey municipalities under 10-year contracts expiring in 2028, 2030 and 2032, respectively. These contracts do not protect us against incurring costs in excess of revenues we earn pursuant to the contracts. There can be no assurance we will not experience losses resulting from these contracts. Losses under these contracts, or our failure or inability to perform or renew such agreements, may have a material adverse effect on our financial condition and results of operations.

Capital market conditions and key assumptions may adversely impact the value of our postretirement benefit plan assets and liabilities.

Market factors can adversely affect (1) the rate of return on assets held in trusts to satisfy our future postretirement benefit obligations and (2) interest rates. Reduced rates of return can increase the level of contributions required by us to satisfy future postretirement benefit obligations. Changes in interest rates impact the discount rates used in the determination of our postretirement benefit actuarial valuations. In addition, changes in demographics, such as increases in life expectancy assumptions, can increase future postretirement benefit obligations. Any negative impact to these factors, either individually or a combination thereof, may have a material adverse effect on our financial condition and results of operations.

An element of our growth strategy is the acquisition of water and wastewater assets, operations, contracts or companies. Any pending or future acquisitions we decide to undertake will involve risks.

The acquisition and/or operation of additional water and wastewater systems is an element of our growth strategy. This strategy depends on identifying suitable opportunities that meet our risk and reward profile and reaching mutually agreeable terms with acquisition candidates or contract parties. Acquisitions may result in dilution in the value of our equity securities, incurrence of debt and contingent liabilities and fluctuations in financial results. In addition, identifying suitable opportunities, negotiating terms, and integrating operations may require management attention without any assurance of achieving a projected outcome. Even if an acquisition is successfully consummated, or we enter into an agreement to operate additional water or wastewater systems, the assets, operations, contracts or companies we acquire may not achieve the projected revenues and profitability.

Our ability to achieve organic customer growth in our market area is dependent on the residential building market. New housing starts and home sale closings are one element that impacts our rate of growth and therefore, may not meet our expectations.

We expect our revenues to increase from customer growth for our regulated water operations as a result of anticipated construction, sale and close of new housing units. If housing starts decline, or do not increase as we have projected, or home sales closing cycle times increase as a result of economic conditions or otherwise, the timing and extent of our organic revenue growth may not meet our expectations, our deferred project costs may not produce revenue-generating projects in the timeframes anticipated and our financial results could be negatively impacted.

There can be no assurance we will continue to pay dividends in the future or, if dividends are paid, that they will be in amounts similar to past dividends.

We have paid dividends on our common stock each year since 1912 and have increased the amount of dividends paid each year since 1973. Our earnings, financial condition, capital requirements, applicable regulations and other factors, including the timeliness and adequacy of rate increases, will determine both our ability to pay dividends and the amount of those dividends. There can be no assurance we will continue to pay dividends in the future or, if dividends are paid, that they will be in amounts similar to past dividends.

If we are unable to pay the principal and interest on our indebtedness as it comes due or we default under certain other provisions of our loan documents, our indebtedness could be accelerated and our results of operations and financial condition could be adversely affected.

Our ability to pay the principal and interest on our indebtedness as it comes due will depend upon our current and future performance. Our performance is affected by many factors, some of which are beyond our control.

We believe cash generated from operations and, if necessary, borrowings under existing credit facilities, will be sufficient to enable us to make our debt payments as they become due. If, however, we do not generate sufficient cash, we may be required to attempt to refinance our obligations or sell additional equity.

No assurance can be given that any refinancing or sale of equity will be possible when needed, or that we will be able to negotiate favorable terms. In addition, our failure to comply with certain provisions contained in our trust indentures and loan agreements relating to our outstanding indebtedness could lead to a default under these documents, which could result in an acceleration of our indebtedness.

The current concentration of our business in central New Jersey and in Delaware makes us susceptible to adverse developments in local regulatory, economic, demographic, competitive and weather conditions.

Our Middlesex System provides water services to customers located primarily in eastern Middlesex County, New Jersey. Water service is provided under wholesale contracts to the Townships of Edison, East Brunswick and Marlboro, the Borough of Highland Park, the Old Bridge Municipal Utilities Authority and the City of Rahway. We also provide water services to customers in the State of Delaware. Our revenues and operating results are therefore subject to local regulatory, economic, demographic, competitive and weather conditions in a relatively concentrated geographic area. A change in any of these conditions could make it more costly for us to conduct our business or reduce the revenue earned in conducting our business.

We are subject to anti-takeover measures that may be used to discourage, delay or prevent changes of control that might benefit non-management shareholders.

Subsection 10A of the New Jersey Business Corporation Act, known as the New Jersey Shareholders Protection Act, applies to us. The Shareholders Protection Act deters merger proposals, tender offers or other attempts to effect changes in control that are not approved by our Board of Directors. In addition, we have a classified Board of Directors, which means only a portion of the Director population is elected each year. A classified Board can make it more difficult for an acquirer to gain control of the Company by voting its candidates onto the Board of Directors and may also deter merger proposals and tender offers. Our Board of Directors also has the ability, subject to obtaining NJBPU approval, to issue one or more series of preferred stock having such number of shares, designation, preferences, voting rights, limitations and other rights as the Board of Directors may fix. This could be used by the Board of Directors to discourage, delay or prevent an acquisition the Board of Directors determines is not in the best interest of the common shareholders.

General Risks

General economic conditions may materially and adversely affect our financial condition and results of operations.

Adverse economic conditions could negatively impact our customers’ water usage demands, particularly the level of water usage demand by our commercial and industrial customers in our Middlesex System. If water demand by our commercial and industrial customers in our Middlesex System decreases, our financial condition and results of operations could be negatively impacted until completion of a subsequent base rate filing.

We rely on our information technology systems to help manage our operations.

Our information technology systems require periodic modifications, upgrades and/or replacement which subject us to costs and risks including potential disruption of our internal control structure, substantial unanticipated capital expenditures, additional operating expenses, retention of sufficiently skilled personnel and other risks in transitioning to new systems or integrating new systems. A failure to modify, upgrade or replace our information technology systems could have an adverse impact on our business. In addition, challenges implementing new technology systems may cause disruptions in our business operations and have an adverse effect on our business operations.

Our information technology systems may be subject to physical and cyber attacks.

We rely on our computer, information and communications technology systems in connection with the operation of our business, especially with respect to customer service and billing, accounting and, in some cases, the monitoring and operation of our operating facilities.  Our computer and communications systems and operations

could be damaged or interrupted by natural disasters, cyber-attacks, power loss and internet, telecommunications or data network failures or acts of war or terrorism or similar events or disruptions.  Any of these or other events could cause service interruption, delays and loss of critical data or, impede aspects of operations and therefore, adversely affect our financial results.

Cyber-attacks could result in the loss, or compromise, of customer, financial or operational data, disruption of billing, collections or normal field service activities, disruption of electronic monitoring and control of operational systems and delays in financial reporting and other management functions. Possible impacts associated with a cyber-incident may include remediation costs related to lost, stolen, or compromised data, repairs to data processing systems, increased cyber security protection costs, adverse effects on our compliance with regulatory and environmental laws and regulations, including standards for drinking water, litigation and reputational damage.

We depend significantly on the technical and management services of our team, and the departure of any of certain persons could cause our operating results to temporarily be short of our expectations.

Our success depends significantly on the continued individual and collective contributions of our team. If we lose the services of certain members of our team, or are unable to attract and retain qualified personnel in key roles, our operating results could be negatively impacted.

None.

Utility Plant

The water utility plant in our systems consists of source of supply, pumping, water treatment, transmission and distribution, general facilities and all appurtenances, including all connecting pipes.

The wastewater utility plant in our systems consist of pumping, treatment, collection mains, general facilities and all appurtenances, including all connecting pipes.

Middlesex System

The Middlesex System’s principal source of surface supply is the Delaware & Raritan Canal owned by the State of New Jersey and operated as a water resource by the NJWSA.

Water is withdrawn from the Delaware & Raritan Canal at New Brunswick, New Jersey through our intake and pumping station, located on state-owned land bordering the canal. Water is transported through two raw water pipelines for treatment and distribution at our CJO Plant in Edison, New Jersey.

The CJO Plant includes chemical storage and chemical feed equipment, two dual rapid mixing basins, four upflow clarifiers which are also called superpulsators, three ozone contactors, twelve rapid filters containing gravel, sand and anthracite for water treatment and a steel washwater tank. The CJO Plant also includes a computerized Supervisory Control and Data Acquisitions system to monitor and control the CJO Plant and the water supply and distribution system in the Middlesex System. There is a State of New Jersey certified on-site laboratory capable of performing bacteriological, chemical, process control and advanced instrumental chemical sampling and analysis.

The design capacity of the CJO Plant is 55 mgd (60 mgd maximum capacity). The five electric motor-driven, vertical turbine pumps presently installed have an aggregate capacity of 85 mgd.

In addition, there is a 15 mgd auxiliary pumping station on-site at the CJO Plant location. It has a dedicated substation and emergency power supply provided by a diesel-driven generator. It pumps from the 10 million gallon distribution storage reservoir directly into the distribution system.

The transmission and distribution system is comprised of 746 miles of mains and includes 24,300 feet of 48-inch concrete transmission main and 23,400 feet of 42-inch ductile iron transmission main connecting the CJO Plant to our distribution pipe network and related storage facilities. Also included are a 58,600 foot transmission main and a 38,800 foot transmission main, augmented with a long-term, non-exclusive agreement with East Brunswick to transport water through the East Brunswick system to several of our other contract customers.

The Middlesex System’s storage facilities consist of a 10 million gallon reservoir at the CJO Plant, 5 million gallon and 2 million gallon reservoirs in Edison and a 2 million gallon reservoir at the Park Avenue Plant.

In New Jersey, we own the properties on which the Middlesex System’s 27 wells are located, the properties on which our storage tanks are located as well as the property where the CJO Plant is located. We own our operations center located at 1500 Ronson Road, Iselin, New Jersey, consisting of a 27,000 square foot office building, 16,500 square foot maintenance facility and a 1.96 acre equipment and materials storage and staging yard. We lease 29,036 square feet of commercial office space adjacent to the Ronson Road complex. The leased space, which is under contract through December 2029, houses our corporate administrative functions including executive, accounting, communications, customer service and billing, engineering, human resources, information technology and legal.

Tidewater System

The Tidewater System is comprised of 85 production plants that vary in pumping capacity from 46,000 gallons per day to 4.4 mgd. Water is transported to our customers through 938 miles of transmission and distribution mains. Storage facilities include 48 tanks, with an aggregate capacity of 9.9 million gallons. The Delaware office property, located on an eleven-acre parcel owned by White Marsh, consists of two office buildings totaling approximately 17,000 square feet. In addition, Tidewater maintains a field operations center servicing its largest service territory in Sussex County, Delaware. The operations center is located on a 2.9 acre parcel owned by White Marsh, and consists of three buildings totaling approximately 12,000 square feet.

Pinelands Water System

Pinelands Water owns well site and storage properties in Southampton Township, New Jersey. The Pinelands Water storage facility is a 1.3 million gallon standpipe. Water is transported to our customers through 18 miles of transmission and distribution mains.

Pinelands Wastewater System

Pinelands Wastewater owns a 12 acre site on which its 0.5 mgd capacity wastewater treatment plant and connecting pipes are located. Its wastewater collection system is comprised of approximately 24 miles of sewer lines.

USA-PA, USA and White Marsh

Our non-regulated subsidiaries, namely USA-PA, USA and White Marsh, do not own utility plant property.

In September 2021, the NJDEP issued a Notice to Middlesex based on self-reporting by Middlesex that the level of Perfluorooctanoic Acid (PFOA) in water treated at its Park Avenue Plant in New Jersey exceeded a recently promulgated NJDEP standard effective in 2021. Neither the NJDEP nor Middlesex characterized this exceedance as an acute health emergency. However, Middlesex was required to notify its affected customers and the Company

complied in due course. Water currently being delivered to customers is in compliance with all USEPA and NJDEP drinking water standards, including the newly established water quality standard for PFOA.

In 2021, the Company was served with two PFOA-related class action lawsuits seeking restitution for medical, water filter replacement and other claimed related costs. On August 30, 2024, the parties to the Vera et al. v. Middlesex Water Company and Lonsk et al v. Middlesex Water Company litigations entered into a signed Settlement Term Sheet (Term Sheet) in a step towards resolution of both matters. The parties are in the process of memorializing the settlement into a Settlement Agreement that is expected to be completed by the parties in the first quarter of 2025. The Company does not believe that the Term Sheet and the anticipated Settlement Agreement, once executed, will have any material financial or operational impact to Middlesex.

The Company is a defendant in other lawsuits in the normal course of business. We believe the resolution of these pending claims and legal proceedings will not have a material adverse effect on the Company’s consolidated financial statements.

Not applicable.

PART II

The Company’s common stock is traded on the NASDAQ Stock Market, LLC, under the symbol MSEX. As of December 31, 2024, there were 1,631 holders of record.

The Company has paid dividends on its common stock each year since 1912. The payment of future dividends is contingent upon the future earnings of the Company, its financial condition and other factors deemed relevant by the Board of Directors at its discretion.

If four or more quarterly dividends are in arrears, the preferred shareholders, as a class, are entitled to elect two members to the Board of Directors in addition to Directors elected by holders of the common stock. In the event dividends on the preferred stock are in arrears, no dividends may be declared or paid on the common stock of the Company.

The Company issues shares of its common stock in connection with its Middlesex Water Company Investment Plan (the Investment Plan), a direct share purchase and dividend reinvestment plan for the Company’s common stock. Since the inception of the Investment Plan and its predecessor plan, the Company has periodically replenished the level of authorized shares in the plans.

The Company maintains a long-term incentive compensation plan for certain management employees where awards are made in the form of restricted common stock. Shares issued in connection with this plan are subject to forfeiture by the employee in the event of termination of employment for any reason within five years of the award, other than as a result of retirement at normal retirement age, death, disability or change in control. The maximum number of shares authorized for award under this plan is 0.3 million shares, of which approximately 70% remain available for future issuance as of December 31, 2024.

The Company maintains a stock plan for its independent members of the Board of Directors as a component of their compensation. In 2024, shares of the Company’s common stock valued at $0.4 million were granted and issued to the Independent Directors. The maximum number of shares authorized for grant under this plan is 0.1 million. Approximately 34% of the authorized shares remain available for future issuance as of December 31, 2024.

The conversion feature of the Company’s no par $7.00 Series Cumulative and Convertible Preferred Stock allows each security holder to convert one convertible preferred share for twelve shares of the Company's common stock. In 2024, 4,275 shares of the Company’s no par $7.00 Series Cumulative and Convertible Preferred Stock were converted into 51,300 shares (approximately $0.4 million) of the Company’s common stock.

Operations

Middlesex Water Company (Middlesex or the Company) has operated as a water utility in New Jersey since 1897 and in Delaware through our wholly-owned subsidiary, Tidewater Utilities, Inc. (Tidewater), since 1992. We are in the business of providing an essential water utility service for domestic, commercial, municipal, industrial and fire protection purposes. We operate water and wastewater systems under contract for governmental entities and private entities primarily in New Jersey and Delaware and also provide regulated wastewater services in New Jersey. We are regulated by state public utility commissions as to rates charged to customers for water and wastewater services, as to the quality of water and wastewater services we provide and as to certain other matters in the states in which our regulated subsidiaries operate. Only our Utility Service Affiliates, Inc. (USA), Utility Service Affiliates (Perth Amboy), Inc. (USA-PA) and White Marsh Environmental Services, Inc. (White Marsh) subsidiaries are not regulated public utilities as related to rates and services quality. All municipal or commercial entities whose utility operations are managed by these entities however, are subject to environmental regulation at the federal and state levels.

Our principal New Jersey water utility system (the Middlesex System) provides water services to approximately 61,000 retail customers, primarily in central New Jersey. The Middlesex System also provides water sales under contract to municipalities in central New Jersey with a total population of over 0.2 million. Our other New Jersey subsidiaries, Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), provide water and wastewater services to approximately 2,500 customers in Southampton Township, New Jersey.

Tidewater Acquisition of the Water Utility Assets of the Town of Ocean View, Delaware

In February 2025, Tidewater and the Town of Ocean View, Delaware’s (Ocean View) joint application for Tidewater’s purchase of all of the rights, title, and interest in the water utility assets of Ocean View for $4.6 million was approved by the Delaware Public Service Commission (DEPSC). Ocean View serves approximately 900 customers in Sussex County, Delaware. Tidewater currently provides water service to most residents of Ocean View other that the 900 customers currently served by Ocean View. Closing on this purchase is expected by April 2025.

United States Environmental Protection Agency (USEPA) Issues Final Perfluoroalkyl (PFAS) Regulations

In April 2024, the USEPA finalized drinking water regulations for PFAS, establishing maximum contaminant levels (MCLs) for three PFAS compounds (Regulated PFAS) that are lower than the current New Jersey Department of Environmental Protection MCLs adhered to by the Company. Under the new USEPA regulations effective April 2024, water systems must monitor for Regulated PFAS and have three years to complete initial monitoring (by April 2027), followed by ongoing compliance monitoring. Water systems must also provide the public with information on the levels of Regulated PFAS in their drinking water beginning in 2027. Water systems have five years (by April 2029) to implement solutions that reduce Regulated PFAS if monitoring shows that drinking water levels exceed these MCLs.

Beginning in April 2029, water systems that have Regulated PFAS in drinking water which exceeds one or more of these MCLs must take action to reduce levels of these PFAS compounds in their drinking water and must provide notification to the public of the violation.

In anticipation of these new USEPA standards, in 2023, the Company began implementing its strategy to meet these lower MCLs for Regulated PFAS and is currently performing preliminary engineering studies to ensure that effective PFAS treatment approaches are implemented.

Capital Construction Program

The Company’s multi-year capital construction program encompasses numerous projects designed to upgrade and replace utility infrastructure as well as enhance the integrity and reliability of assets to better serve the current and future generations of water and wastewater customers. The Company plans to invest approximately $93 million in 2025 in connection with this plan for projects that include, but are not limited to:

Strategy for Growth

Our strategy for selective and sustainable growth is focused on the following key areas:

Rates

Middlesex - The approval by the NJBPU in February 2024 of the negotiated settlement of the Middlesex 2023 base rate case is expected to increase annual operating revenues by $15.4 million, effective March 1, 2024. The approved tariff rates were designed to recover increased operating costs as well as a return on invested capital of $563.1 million, based on an authorized return on common equity of 9.6%. Middlesex has made capital infrastructure investments to ensure prudent upgrade and replacement of its utility assets to support continued regulatory compliance, resilience and overall quality of service. In August 2023, Middlesex and 3M Company (3M) executed a settlement agreement (Settlement Agreement) to resolve a lawsuit Middlesex previously initiated claiming 3M introduced Perfluoroalkyl Substances (PFAS) into the Company’s water supply for its Park Avenue Wellfield Treatment Plant (Park Avenue Plant). The rate case settlement provided that the net proceeds from the 3M Settlement Agreement were to be used to mitigate the increase in customer rates and reimburse Middlesex for previously incurred costs for the construction of the Park Avenue Plant PFAS treatment upgrades, including depreciation and carrying costs. This resulted in the reclassification of $48.3 million from Regulatory Liabilities to Contributions in Aid of Construction from the December 31, 2023 balance sheet. In 2024, the Company also recognized the recovery of $0.9 million for depreciation and $4.1 million for carrying costs associated with the Park Avenue Plant PFAS treatment upgrades, as well as the recovery of $2.6 million of previously incurred operating treatment costs while the Park Avenue Plant PFAS treatment upgrades were in process.

The Middlesex Lead Service Line Replacement (LSLR) Plan, which was approved by the NJBPU in January 2024, has commenced and Middlesex is currently recovering $1.2 million of costs for replacing customer-owned lead service lines incurred through June 2024, which are being recovered between September 2024 and February 2025. Costs of $0.6 million for replacing customer-owned lead service lines incurred between July 2024 through December 2024 will be recovered beginning in March 2025 through August 2025. The LSLR surcharge is required to be reset every six months over the life of the LSLR Plan. Cost recovery for replacing Company-owned lead service lines are recoverable through traditional rate making in connection with general rate case filings.

In October 2023, the NJBPU approved Middlesex’s petition for a Distribution System Improvement Charge (DSIC) Foundation Filing, which is a prerequisite to implementing a DSIC rate that allows water utilities to recover investments in, and generate a return on, qualifying capital improvements to their water distribution system made between base rate proceedings. Middlesex is authorized to recover DSIC revenues up to five percent (5%) of total revenues established in Middlesex’s 2021 base rate proceeding, or approximately $5.5 million. Semi-annually, beginning in April 2024, the Company must file for a change in its DSIC rate seeking recovery for DSIC-eligible investments made during the period. DSIC rates remain in effect until Middlesex’s next base rate case increase subsequent to the March 1, 2024 increase. Under the terms of the Foundational Filing, the Company is required to file a base rate petition before November 2026.

In May 2024, the NJBPU approved a DSIC rate, effective May 26, 2024, that is expected to result in $0.5 million of annual revenue. In November 2024, the NJBPU approved a DSIC rate, effective November 26, 2024, that is expected to result in an additional $0.6 million of annual revenue. Middlesex expects to file for an additional DSIC rate increase in April 2025.

In February 2025, the NJBPU approved Middlesex’s petition to reset its Purchased Water Adjustment Clause (PWAC) tariff rate to recover additional annual costs of $0.5 million, primarily for the purchase of treated water from a non-affiliated water utility regulated by the NJBPU. A PWAC is a rate mechanism that allows for the recovery of increased purchased water costs between base rate case filings. The PWAC is reset to zero once those increased costs are included in base rates. The new PWAC rate will be effective March 1, 2025.

Tidewater - In September 2024, the DEPSC approved Tidewater’s petition to recover up to $2.1 million of costs associated with Tidewater’s obligation to identify and inventory lead service lines throughout Tidewater’s service area, as required by federal law and Delaware regulations. Recovery of these costs began February 1, 2025 and is expected to continue through January 2028. Through December 31, 2024, Tidewater has spent $1.8 million, which is included in Regulatory Assets.

In August 2024, Tidewater filed an application with the DEPSC to increase its general rates for water service. In the application, Tidewater seeks an overall increase in annual operating revenue of $10.3 million or 25.66% over current revenue. The request for rate increases will allow Tidewater to recover prudently incurred investments made in the last ten years to support continued regulatory compliance, enhanced water quality, service reliability, security and resiliency of the water utility infrastructure assets. Effective October 30, 2024, Tidewater received approval of the DEPSC to suspend its DSIC rate and implement an interim rate increase, which is expected to result in approximately $2.5 million of annual revenues, subject to refund pending the outcome of the rate case application.

Southern Shores - Southern Shores provides water service to a 2,200 unit condominium community in Sussex County, Delaware under a DEPSC-approved agreement expiring December 31, 2029.  Under the agreement, rates are increased when there are unanticipated capital expenditures or regulatory related changes in operating expenses exceed certain thresholds. In 2024, capital expenditures did exceed the established threshold. In addition, rates are increased annually by the lesser of the regional Consumer Price Index or 3%. Effective January 1, 2025, Southern Shores rates were increased $0.1 million or 6.51%.

Outlook

Our ability to increase operating income and net income is based significantly on four factors: weather, adequate and timely rate relief, effective cost management and customer growth (which are evident in comparison discussions in the Results of Operations section below). Weather patterns which can result in lower customer demand for water may occur in 2025. As operating costs are anticipated to increase in 2025 in a variety of categories, we continue to implement plans to further streamline operations and further reduce and mitigate increases in operating costs. Changes in customer water usage habits, as well as increases in capital expenditures and operating costs, are significant factors in determining the timing and extent of rate increase requests.

Our investments in system infrastructure continue to grow significantly and our operating costs are anticipated to increase in 2025 and 2026 in a variety of categories. These factors, among others, may require a base rate increase request by Middlesex in mid 2025.

Overall, organic residential customer growth continues in our Tidewater system (approximately 3.5% in 2024).

The Company has projected to spend approximately $387 million for the 2025-2027 capital investment program, including approximately $105 million for upgrading our Carl J. Olson Surface Water Treatment Plant (CJO Plant) to integrate PFAS removal from source water, $34 million on the RENEW Program, which is our ongoing initiative to replace water mains in the Middlesex System, $15 million for replacement of a transmission main in Metuchen in our Middlesex System and $12 million for elevated storage tanks in our Tidewater System.

Operating Results by Segment

The Company has two operating segments, Regulated and Non-Regulated. Our Regulated segment contributed approximately 93% of total revenues for the years ended December 31, 2024, 2023 and 2022, respectively, and approximately 94%, 92% and 93% of net income for the years ended December 31, 2024, 2023 and 2022, respectively. The discussion of the Company’s results of operations is on a consolidated basis and includes significant factors by subsidiary. The segments in the tables included below are comprised of the following companies: Regulated- Middlesex, Tidewater, Pinelands and Southern Shores; Non-Regulated- USA, USA-PA, and White Marsh.

Results of Operations for 2024 as Compared to 2023

Operating Revenues

Operating revenues for the year ended December 31, 2024 increased $25.6 million from the same period in 2023 due to the following factors:

Operation and Maintenance Expense

Operation and maintenance expenses for the year ended December 31, 2024 increased $9.2 million from the same period in 2023 due to increased legal, financial and regulatory matter costs, increased labor costs due to annual wage increases, an enhanced water treatment process at Middlesex’s Park Avenue Plant, and higher energy costs due to increased water demand.

Depreciation

Depreciation expense for the year ended December 31, 2024 decreased $0.8 million from the same period in 2023 due to recovery of prior year depreciation related to upgrades at the Park Avenue Plant partially offset by a higher level of utility plant in service. The conclusion of Middlesex’s base rate increase request allowed proceeds from the 3M Settlement Agreement to reimburse Middlesex for previously incurred costs for the construction of the Park Avenue Plant PFAS treatment upgrades (for further discussion of the 3M Settlement Agreement, see Rates, Middlesex above).

Other Taxes

Other taxes for the year ended December 31, 2024 increased $3.1 million from the same period in 2023 primarily due to higher gross receipts taxes on higher revenue in Middlesex and higher payroll related taxes on increased labor costs.

Other Income, net

Other Income, net for the year ended December 31, 2024 increased $5.6 million from the same period in 2023 primarily due to the recovery of carrying costs on the PFAS treatment upgrades at the Park Avenue Plant and higher actuarially-determined retirement benefit plans non-service benefit offset by lower allowance for funds used during construction on capital projects in construction.

Interest Charges

Interest charges for the year ended December 31, 2024 increased $0.9 million from the same period in 2023 due to higher average debt outstanding and higher average interest rates.

Income Taxes

Income taxes for the year ended December 31, 2024 increased by $5.9 million from the same period in 2023, primarily due to higher pre-tax income and lower income tax benefits associated with decreased repair expenditures on tangible property in the Middlesex System offset by the recovery of income taxes on the taxable portion of the proceeds from the 3M Settlement Agreement.

Results of Operations for 2023 as Compared to 2022

Operating Revenues

Operating revenues for the year ended December 31, 2023 increased $3.8 million from the same period in 2022 due to the following factors:

Operation and Maintenance Expense

Operation and maintenance expenses for the year ended December 31, 2023 increased $4.0 million from the same period in 2022 due to increased variable production costs due to weather-driven changes in water quality and higher chemical prices, higher outside service costs due to production instrumentation calibration activities, increases in labor costs due to wage increases and higher bad debt expense due to higher anticipated customer receivable write-offs. Partially offsetting these increases was lower weather-related main break activity in our Middlesex System during the winter months.

Depreciation

Depreciation expense for the year ended December 31, 2023 increased $2.2 million from the same period in 2022 due to a higher level of utility plant in service.

Other Taxes

Other taxes for the year ended December 31, 2023 increased $0.5 million from the same period in 2022 primarily due to higher revenue related taxes on increased revenues in our Middlesex system.

Gain on Sale of Subsidiary

Middlesex recognized a $5.2 million gain on the sale of its regulated Delaware wastewater subsidiary in January 2022.

Other Income, net

Other Income, net for the year ended December 31, 2023 decreased $1.2 million from the same period in 2022 primarily due to lower actuarially-determined retirement benefit plans non-service benefit.

Interest Charges

Interest charges for the year ended December 31, 2023 increased $3.8 million from the same period in 2022 due to higher average debt outstanding and higher average interest rates in 2023 as compared to 2022.

Income Taxes

Income taxes for the year ended December 31, 2023 decreased by $2.2 million from the same period in 2022, primarily due to greater income tax benefits associated with increased repair expenditures on tangible property in the Middlesex System and lower pretax income due to gain on the sale of a subsidiary in 2022.

Liquidity and Capital Resources

Cash Flows from Operating Activities

Cash flows from operating activities are largely influenced by four factors: weather, adequate and timely rate increases, effective cost management and customer growth. The effect of those factors on net income is discussed in the Results of Operations section above.

For the year ended December 31, 2024, cash flows from operating activities increased $5.9 million to $58.7 million. The increase in cash flows from operating activities primarily resulted from the impact of higher weather-driven customer demand and Middlesex’s approved base rate increase effective March 1, 2024.

Increases in certain operating costs impact our liquidity and capital resources. We continually monitor the need for timely rate filing to minimize the lag between the time we experience increased operating costs and capital expenditures and the time we receive appropriate rate relief. .

Cash Flows from Investing Activities

For the year ended December 31, 2024, cash flows used in investing activities decreased $15.6 million to $74.6 million due to decreased utility plant expenditures in 2024. In 2023, the Company had significant utility plant

expenditures for the construction of a facility to provide an enhanced treatment process at the Company’s Park Avenue Plant to comply with new state water quality regulations relative to PFAS.

For further discussion on the Company’s future capital expenditures and expected funding sources, see “Capital Expenditures and Commitments” below.

Cash Flows from Financing Activities

For the year ended December 31, 2024, cash flows from financing activities decreased $18.2 million to $17.7 million. The decrease in cash flows provided by financing activities is due to lower proceeds from the issuance of common stock under the Middlesex Water Company Investment Plan (Investment Plan) and long-term debt offset by proceeds received from a litigation settlement.

For further discussion on the Company’s short-term and long-term debt, see “Sources of Liquidity” below.

Capital Expenditures and Commitments

To fund our capital program, we use internally generated funds, short-term and long-term debt borrowings, proceeds from sales of common stock under the Investment Plan and, when market conditions are favorable, proceeds from sales to the public of our common stock.

The table below summarizes our estimated capital expenditures for the years 2025-2027.

Our estimated capital expenditures for the items listed above are primarily comprised of the following:

The actual amount and timing of capital expenditures is dependent on the need for replacement of existing infrastructure, customer growth, residential new home construction and sales, project scheduling and continued refinement of project scope and costs.

To fund our capital program in 2025, we estimate we will utilize some or all of the following:

Sources of Liquidity

Short-term Debt - The Company has available lines of credit of $140 million. The outstanding borrowings under the credit lines at December 31, 2024 were $23.0 million, at a weighted average interest rate of 5.63%.

The weighted average daily amounts of borrowings outstanding under the credit lines and the weighted average interest rates on those amounts were $38.7 million and $35.7 million at 6.33% and 6.13% for the years ended December 31, 2024 and 2023, respectively.

Long-term Debt - Subject to regulatory approval, the Company periodically issues long-term debt to fund investments in utility plant. To the extent possible and fiscally prudent, the Company finances qualifying capital projects under SRF loan programs in New Jersey and Delaware. These government programs provide financing at interest rates typically below rates available in the broader financial markets.

Middlesex has received approval from the NJBPU to borrow up to $300.0 million from the New Jersey SRF Program, the New Jersey Economic Development Authority, private placement and other financial institutions as needed through December 31, 2025. The Company expects to issue debt securities in a series of one or more transaction offerings to help fund Middlesex’s multi -year capital construction program.

In September 2024, Tidewater closed on a $2.2 million Delaware SRF loan with a 0.0% interest rate with an expected maturity date in 2044. This loan is for costs associated with Tidewater’s obligation, as required by federal law and Delaware regulations, to identify and inventory lead service lines throughout Tidewater’s service area. Tidewater has drawn down $1.7 million as of December 31, 2024.

In May 2024, Tidewater closed on four DEPSC-approved Delaware SRF loans totaling $5.6 million, all at interest rates of 2.0% with expected maturity dates in 2044. These loans are for the construction, relocation, improvement, and/or interconnection of transmission mains and construction of a water treatment facility. Tidewater has drawn down less than $0.1 million on these loans as of December 31, 2024. Each project has its own construction timetable with the last spending set to occur in 2026.

Tidewater also has two active construction projects funded by Delaware SRF loans totaling $8.3 million with remaining availability of funds for borrowing. These loans are for the construction of a one-million gallon elevated storage tank and construction, relocation, improvement, and interconnection of transmission mains. Tidewater has drawn a total of $4.9 million through December 31, 2024 and expects that the requisitions will continue through the second quarter of 2025.

In July 2023, Pinelands Water and Pinelands Wastewater closed on $3.9 million and $3.6 million CoBank, ACB (CoBank) amortizing mortgage type loans, respectively, with an interest rate of 6.17% and a final maturity date of 2043 for each loan. Proceeds were used to pay off outstanding intercompany loans with Middlesex and for ongoing capital projects.

In May 2023, Tidewater closed on a $20.0 million loan from CoBank with an interest rate of 5.71% and a 2033 maturity date and fully drew all funds by June 30, 2023. Proceeds from the loan were used to pay off Tidewater’s outstanding balances under its bank lines of credit and for other general corporate purposes.

In April 2023, Tidewater closed on two DEPSC-approved Delaware SRF loans totaling $6.9 million, all at interest rates of 2.0% with maturity dates in 2043 and 2044. These loans are for the construction, relocation, improvement, and/or interconnection of transmission mains. Tidewater has fully drawn on these loans.

In March 2023, Middlesex closed on a $40.0 million, 5.24% private placement of First Mortgage Bonds (FMBs) with a 2043 maturity date designated as Series 2023A. Proceeds were used to reduce the Company’s outstanding balances under its bank lines of credit.

In May 2022, Middlesex repaid its two outstanding New Jersey Infrastructure Bank (NJIB) construction loans by issuing FMBs to the NJIB under two loan agreements. The total amount of FMBs issued is $52.2 million and designated as Series 2022A ($16.2 million) and Series 2022B ($36.0 million). The interest rate on the Series 2022A bond is zero and the interest rate on the Series 2022B bond ranges between 2.7% and 3.0%. The final maturity date for both FMBs is August 1, 2056, with scheduled debt service payments over the life of these loans.

Substantially all of the utility plant of the Company is subject to the lien of its mortgage, which includes debt service and capital ratio covenants. The Company is in compliance with all of its mortgage covenants.

Common Stock - The Company issues shares of its common stock in connection with the Investment Plan, a direct share purchase and dividend reinvestment plan for the Company’s common stock. The Company raised approximately $1.0 million through the issuance of shares under the Investment Plan during 2024. In May 2023, Middlesex received approval from the NJBPU to increase the number of authorized shares under the Investment Plan by 0.7 million shares. Currently, 0.7 million shares remain registered with the United States Securities and Exchange Commission and available for issuance to participants under the Investment Plan.

In order to fully fund the ongoing capital investment program and maintain a balanced capital structure required for a regulated water utility, Middlesex may offer for sale additional shares of its common stock. The amount, the timing and the sales method of the common stock is dependent on the timing of the construction expenditures, the level of additional debt financing and financial market conditions. Common stock offerings will occur as needed to maintain a balanced capital structure as we continue on a parallel path with future debt offerings.

In April 2023, Middlesex received approval from the NJBPU to issue and sell up to 1.0 million shares of its common stock, without par value, through December 31, 2025. Sales of additional shares of common stock are part of the Company’s comprehensive financing plan to fund its multi-year utility plant infrastructure investment program. As described above in “Long-term Debt”, the NJBPU also approved the debt funding component of the financing plan.

Contractual Obligations

In the course of normal business activities, the Company enters into a variety of contractual obligations and commercial commitments. Some result in direct obligations on the Company’s balance sheet while others are commitments, some firm and some based on uncertainties, which are disclosed in the Company’s consolidated financial statements.

The table below presents our known contractual obligations for the periods specified as of December 31, 2024.

The table above does not reflect any anticipated cash payments for retirement benefit plan obligations. The effect on the timing and amount of these payments resulting from potential changes in actuarial assumptions and returns on plan assets cannot be estimated. In 2024, the Company contributed $3.7 million to its retirement benefit plans and expects to contribute approximately $1.8 million in 2025.

We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements, or for other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts.

Critical Accounting Policies and Estimates

The application of accounting policies and standards often requires the use of estimates, assumptions and judgments. The Company regularly evaluates these estimates, assumptions and judgments, including those related to the calculation of pension and other retirement benefits, unbilled revenues, and the recoverability of certain assets, including regulatory assets. The Company bases its estimates, assumptions and judgments on historical experience and current operating environment. Changes in any of the variables that are used for the Company’s estimates, assumptions and judgments may lead to significantly different financial statement results.

Our critical accounting policies and estimates are set forth below.

Regulatory Accounting

We maintain our books and records in accordance with accounting principles generally accepted in the United States of America. Middlesex and certain of its subsidiaries are subject to regulation in the states in which they operate. Those companies are required to maintain their accounts in accordance with regulatory authorities’ rules and guidelines, which may differ from other authoritative accounting pronouncements. In those instances, the Company follows the guidance in the Financial Accounting Standards Board Accounting Standards Codification Topic 980 Regulated Operations (Regulatory Accounting).

In accordance with Regulatory Accounting, costs and obligations are deferred if it is probable that these items will be recognized for rate-making purposes in future rates. Accordingly, we have recorded costs and obligations, which will be amortized over various future periods. Any change in the assessment of the probability of rate-making treatment would require us to change the accounting treatment of the deferred item. We have no reason to believe any of the deferred items that are recorded will be treated differently by the regulators in the future.

Revenues

Revenues from our regulated customers, which include amounts billed quarterly to residential customers and monthly to industrial, commercial, fire-protection and wholesale customers, also include unbilled amounts based upon estimated usage from the date of the last meter reading to the end of the accounting period. While actual usage for customers may differ from the estimate, we believe the overall total estimate of consumption and revenue for the fiscal period will not differ materially from actual consumption.

Retirement Benefit Plans

We maintain a noncontributory defined benefit pension plan (Pension Plan) which covers all currently active employees hired prior to April 1, 2007. In addition, the Company maintains an unfunded supplemental plan for certain executive officers.

The Company has a retirement benefit plan other than pensions (Other Benefits Plan) for substantially all of its retired employees. Employees hired after March 31, 2007 are not eligible to participate in the Other Benefits Plan. Coverage includes healthcare and life insurance.

The costs for providing retirement benefits are dependent upon numerous factors, including actual plan experience and assumptions of future experience. Future retirement benefit plan obligations and expense will depend on future investment performance, changes in future discount rates and various other demographic factors related to the population participating in the Company’s retirement benefit plans, all of which can change significantly in future years.

The primary assumptions used for determining future retirement benefit plans’ obligations and costs, which are reviewed and revised as needed each year, are as follows:

The discount rate, compensation increase rate and long-term rate of return used to determine future obligations of our retirement benefit plans as of December 31, 2024 are as follows:

For the 2024 valuation, costs and obligations for our Other Benefits Plan assumed an 8.0% annual rate of increase in the per capita cost of covered healthcare benefits in 2025 with the annual rate of increase declining 0.15% per year for 2026-2045, resulting in an annual rate of increase in the per capita cost of covered healthcare benefits of 5.0% by year 2045.

The following is a sensitivity analysis for certain actuarial assumptions used in determining projected benefit obligations (PBO) and expenses for our retirement benefit plans:

Pension Plan

Other Benefits Plan

Recent Accounting Standards

See Note 1(q) of the Notes to Consolidated Financial Statements for a discussion of recent accounting pronouncements.

We are exposed to market risk associated with changes in interest rates and commodity prices. The Company is subject to the risk of fluctuating interest rates in the normal course of business. Our policy is to manage interest rates through the use of fixed rate long-term debt and, to a lesser extent, variable rate short-term debt. The Company’s interest rate risk related to existing fixed rate, long-term debt is not material due to the term of the majority of our First Mortgage Bonds, which have final maturity dates ranging from 2026 to 2059. Over the next twelve months, approximately $7.7 million of the current portion of existing long-term debt instruments will mature. The Company manages its interest rate risk related to existing variable-rate short-term debt by limiting our variable rate exposure. Applying a hypothetical change in the rate of interest charged by 10% on those fixed- and variable-rate borrowings would not have a material effect on our earnings. Fixed rate long-term debt and variable rate short-term debt agreements were not entered into for trading purposes.

Our risks associated with commodity price increases for chemicals, electricity and other commodities are reduced through contractual arrangements and the ability to recover price increases through rates. Non-performance by these commodity suppliers could have a material adverse impact on our results of operations, financial position and cash flows.

We are exposed to credit risk for both our Regulated and Non-Regulated business segments. Our Regulated operations serve residential, commercial, industrial and municipal customers while our Non-Regulated operations engage in business activities with developers, government entities and other customers. Our 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. Our 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. Our credit portfolio is diversified with no significant customer or industry concentrations. In addition, our 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 benefit plan assets are exposed to the market price variations of debt and equity securities. Changes to the Company's retirement benefit plan assets’ value can impact the Company's retirement benefit plan expense, funded status and future minimum funding requirements. Our exposure to market price risk in our retirement benefit plan assets is managed through our ability to recover retirement benefit plan costs through customer rates. There were no material changes to our primary market risk exposures or how such exposures are managed in 2024 nor are there expected to be in the future.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Middlesex Water Company:

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 the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's consolidated financial statements and an opinion 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 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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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 degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

We have served as the Company's auditor since 2006.
