Reworded

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 and distribution 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.

Reworded

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. Reductions of or delays in weather forecasting could adversely affect our ability to plan and respond to such events, which may exacerbate the impact of such an event. 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.part, in a timely manner or at all.

Added

Disruptions in our supply chain related to goods, such as pipe, chemicals, power and other fuel, equipment, water and other raw materials could adversely impact our operations, financial position, and cash flows.

Added

Our ability to serve our customers and operate our business in compliance with regulatory requirements is dependent upon purchasing or securing necessary goods from our suppliers and vendors. These items include but are not limited to chemicals, pipe, valves, hydrants, fittings, equipment (including personal protective equipment), water, and power and other fuel. Examples of supply chain disruptions include reduced quantities of goods available in the marketplace, delays in manufacturing or shipping goods, labor shortages at our suppliers or vendors, natural or other disasters and operational impacts to some of our suppliers or vendors. Disruptions in our supply chain related to goods have occurred and we anticipate may continue to occur in the future.

Added

Supply chain disruptions may cause us to be unable to purchase or otherwise obtain needed goods at a reasonable price or at all, and may significantly increase the price of goods we may obtain from suppliers and vendors. This, in turn, may adversely impact our operations and our ability to serve our customers in compliance with regulatory requirements, as well as our associated results of operations, cash flows and financial condition. While we attempt to plan for and have contingencies in place to address supply chain disruptions, our mitigation efforts may not be successful or may have further negative impacts on us.

Reworded

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 in New Jersey 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.

Added

Certain costs are not completely within our control. The failure to obtain any rate increase would limit our ability to increase our revenues and, unless we are able to reduce costs without degrading service quality, would result in reduced earnings. Even if the rates approved are sufficient, we face the risk that we will not achieve the rates of return on equity permitted by the applicable Public Utility Commission. This could occur if certain conditions exist, including, but not limited to, (i) water usage is less than the level anticipated in establishing rates, (ii) customers increase their conservation efforts, (iii) we experience unusual or emergent situations, events or conditions, (iv) a decrease in customers that causes a decrease in operating revenue, or (v) our investments or expenses prove to be higher than the levels estimated in establishing rates.

Removed

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.

Reworded

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 finedsubject to fines, penalties or subject to other sanctions, as well as damage to our reputation, as a result of governmental proceedings and private litigation, which could adversely impact our business or results of operations.

Reworded

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 orand to pay for some of the costs of improvements to or the expansion of our utility system assets. OurNeither we nor our regulated utility companies cannotcan issue debt or equity securities without prior regulatory approval.

Added

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. In addition, many acquisitions or operational arrangements involving regulated water and wastewater systems are subject to approval by one or more governmental or regulatory authorities, which may include Public Utility Commissions or similar bodies with jurisdiction over rates, service territories, ownership changes, or operating authority. There can be no assurance that such approvals will be obtained on acceptable terms, in a timely manner, or at all, and regulatory authorities may impose conditions, limitations, or requirements that increase costs, restrict operations, delay integration, or reduce the anticipated benefits of a transaction.

Reworded

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.

Reworded

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.

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

Reworded

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 treatment solutions that reduce Regulated PFAS if monitoring shows that drinking water levels exceed these MCLs. The USEPA has announced its plans to issue a proposed rule extending the compliance date to 2031.

Reworded

Beginning in April 2029,2029 and absent an extension by the USEPA, 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.

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.

Removed

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.

Removed

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.

Removed

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.

Removed

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%.

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.

Removed

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.
