Current report

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.

Current report

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.

Current report

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 onus.

Current report

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 paragraphs (10)

Previous wording

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.

Previous wording

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.

Current wording

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, in a timely manner or at all.

Previous wording

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.

Previous wording

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.

Current wording

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.

Previous wording

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.

If we fail to comply with environmental or other laws and regulations to which our business is subject, we could be subject to fines, penalties or 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.

Previous wording

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.

Current wording

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 and to pay for some of the costs of improvements to or the expansion of our utility system assets. Neither we nor our regulated utility companies can issue debt or equity securities without prior regulatory approval.

Previous wording

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.

Current wording

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 $506 million for capital projects through 2028. 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.

Previous wording

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.

Previous wording

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.
