About The York Water Company

We were organized under the laws of the Commonwealth of Pennsylvania in 1816 and are the oldest investor-owned water utility in the United States. The primary business of the Company is to impound, purify to meet or exceed safe drinking water standards and distribute water. We also own and operate two wastewater collection systems and five wastewater collection and treatment systems. We operate within our franchised water and wastewater territory, which covers portions of 51 municipalities within three counties in south-central Pennsylvania. We are regulated by the Pennsylvania Public Utility Commission, or PPUC, for both water and wastewater in the areas of billing, payment procedures, dispute processing, terminations, service territory, debt and equity financing and rate setting. We must obtain PPUC approval before changing any practices associated with the aforementioned areas.

Water service is supplied through our own distribution system. We obtain the bulk of its water supply from both the South Branch and East Branch of the Codorus Creek, which together have an average daily flow of 73.0 million gallons. This combined watershed area is approximately 117 square miles. We have two reservoirs, Lake Williams and Lake Redman, which together store approximately 2.2 billion gallons of water. We supplement our reservoirs with a 15-mile pipeline from the Susquehanna River to Lake Redman which provides access to an additional supply of 12.0 million gallons of untreated water per day. We also own nine wells which are capable of providing a safe yield of approximately 597,000 gallons per day to supply water to the customers of our satellite systems in Adams County. As of December 31, 2021, our average daily availability was 39.6 million gallons, and average daily consumption was approximately 20.1 million gallons. Our service territory had an estimated population of 204,000 as of December 31, 2021. Industry within our service territory is diversified, manufacturing such items as fixtures and furniture, electrical machinery, food products, paper, ordnance units, textile products, air conditioning systems, laundry detergent, barbells, and motorcycles.

Corporate Information

Our principal executive offices are located at 130 East Market Street, York, Pennsylvania 17401. Our telephone number is (717) 845-3601. Our website address is www.yorkwater.com. The information contained on our website is not incorporated by reference into, and does not form any part of, this preliminary prospectus.

Our Mission Statement

The York Water Company is committed to providing our customers with safe, dependable, high-quality water, wastewater, and related services that meet or exceed customer expectations at reasonable rates in an environment encouraging dedicated employees to achieve their highest standard of performance while earning a fair return for our shareholders.

Our Business Strategy

Invest in Projects, Products and Services that Complement our Core Water and Wastewater Competencies and Extend the Reach of Our Utility Services to Additional Customers

We continuously upgrade and replace utility infrastructure as well as enhance the integrity and reliability of assets to better serve current and future generations of water and wastewater customers. Each acquisition requires a detailed asset management inventory and improvement program to improve acquired assets to our operating,

TABLE OF CONTENTS

reliability, and redundancy standards. We have identified $94.0 million of capital expenditure projects in 2022 and 2023 for routine transmission and distribution projects as well as additional main extensions, dam improvements, an elevated water tank, water treatment plant construction, and various replacements of infrastructure.

Timely and Adequate Recovery of Infrastructure Investments and Other Costs to Maintain Service Quality

From time to time, we file applications for rate increases with the PPUC and are granted rate relief as a result of such requests. Most recently, the PPUC authorized an increase in rates effective March 1, 2019. We anticipate filing a rate increase request in 2022. The PPUC permits water utilities to collect a distribution system improvement charge, or DSIC. The DSIC allows us to add a charge to customers’ bills for qualified replacement costs of certain infrastructure without submitting a rate filing. This surcharge mechanism typically adjusts periodically based on additional qualified capital expenditures completed or anticipated in a future period.

Prudent Acquisition of Water and Wastewater Utilities

Numerous municipally-owned and investor-owned regulated water and wastewater utility systems operate in or near our service territory. We have extensive experience acquiring and integrating other market participants and assets. In 2020, we acquired the wastewater collection and treatment facilities of the Letterkenny Township Municipal Authority, expanding our territory into our third county in southcentral Pennsylvania and our 51^st municipality. In 2021, we acquired the wastewater collection assets of West Manheim Township adding approximately 1,800 wastewater customers. Often the acquired systems are underperforming and require capital investment to bring the systems up to our standards.

Geographic Footprint and Certificated Territory

Our certificated territory in south-central Pennsylvania positions us to serve customers who often commute to Baltimore, Maryland and Washington, DC but who prefer the quality of life and cost of living in Pennsylvania. Our organic growth has benefitted from the recent active housing market, and our developer-friendly main extension protocols entice development in and adjacent to our certificated territory.

Provide Exceptional Services and Maintain Commitment to our Status as a Trusted Brand

We take pride in our ability to provide quality and life-sustaining water and wastewater utility services. Thousands of individual homes and businesses depend on our exceptional levels of service quality. This serious responsibility to deliver value to our customers, communities and shareholders motivates us to seek out ways to continually improve our business for the benefit of customers and shareholders.

Our Competitive Strengths

Demonstrated Earnings Power

Our earnings are principally derived from the return on investment we earn on our utility assets. In the five years from 2017 to 2021, we successfully grew revenues from $48.6 million to $55.1 million. In the same period, earnings per share have risen from $1.01 to $1.30. We have provided an average return on equity of 11.0% over that period.

Operations in Constructive Regulatory Jurisdictions

We currently have our regulated utility operations in Pennsylvania which typically ranks as one of the best states in providing a constructive regulatory environment for utility operations. We have a wealth of experience working alongside regulators to provide quality water and wastewater services. Members of the management team are recruited to serve on a variety of committees and boards at the state and national level, including the American Water Works Association, the National Association of Water Companies, the Water Works Operators Association of Pennsylvania, the Pennsylvania Water Utility Council, the Pennsylvania Water Resources Advisory Council, and the Pennsylvania Technical Advisory Committee.

Significant Opportunities for Investment in Infrastructure

We are able to leverage our expertise in infrastructure improvements to improve safety and reliability throughout the territory in which we operate. We have identified approximately $94.0 million of capital

TABLE OF CONTENTS

expenditure projects in the next two years to provide a safe, adequate, and reliable supply of drinking water and to maintain proper handling and disposal of wastewater for our growing customer base. We are committed to redundancy in all systems, including information technology. This focus and investment mitigates risk of a potential single point of failure.

History of Dividend Growth

Our singular accomplishment of 608 consecutive dividends over 205 continuous years of operation distinguishes us from all other publicly traded utilities. We have never missed a dividend in over 200 years, which is believed to be the longest record of consecutive dividends in America. In 2021, we returned $0.76 per share in dividends to our investors. This represents a 4.0% increase over dividends paid in 2020. We have increased our dividend each year for 25 consecutive years.

Commitment to Environmental and Social Responsibility

We consider environmental and social responsibility to include environmental leadership and sustainability, operational excellence, employee engagement, safety, inclusion and diversity, active community engagement, civic and charitable involvement, and transparency. We integrate environmental and social responsibility policies and practices into our daily operations.

Dedicated Board of Directors

We are governed by an experienced and dedicated Board of Directors who are well versed in public company governance and market strategy. The Board focuses on accountability, responsibility, reliability, and innovation in setting our corporate agenda. The Board is comprised of a diverse complement of directors who appreciate the importance of our culture and history, while looking for opportunities to advance financial and operational efficiencies.

Experienced Management Team

Our senior management team is highly experienced in the water and wastewater utility industry. JT Hand, President and CEO, has been with the Company for 14 years. The team is supported by a deep roster of diverse employees in leadership positions with extensive experience in the operation of regulated utility businesses.

There are certain risks related to conflicts of interest for insurance companies and employee benefit plans.

Any insurance company or fiduciary of a pension plan or other employee benefit plan that is subject to the prohibited transaction rules of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or the Internal Revenue Code of 1986, as amended, including an IRA or a Keogh plan (or a governmental plan to

S-6

TABLE OF CONTENTS

which similar prohibitions apply), and that is considering an investment in York Water Common Stock with the assets of the insurance company or the assets of such a plan, should consult with its counsel regarding whether the purchase of York Water Common Stock could be a “prohibited transaction” under ERISA, the Internal Revenue Code or any substantially similar prohibition. This is discussed in more detail under “Certain ERISA Considerations” below.

Risks Related to the Operation and Regulation of Our Business

The rates we charge our customers are subject to regulation. If we are unable to obtain government approval of our requests for rate increases, or if approved rate increases are untimely or inadequate to cover our investments in utility plant and equipment and projected expenses, our results of operations may be adversely affected.

Our ability to maintain and meet our financial objectives is dependent upon the rates we charge our customers, which are subject to approval by the PPUC. We file rate increase requests with the PPUC, from time to time, to recover our investments in utility plant and equipment and projected expenses. Any rate increase or adjustment must first be justified through documented evidence and testimony. The PPUC determines whether the investments and expenses are recoverable, the length of time over which such costs are recoverable, or, because of changes in circumstances, whether a remaining balance of deferred investments and expenses is no longer recoverable in rates charged to customers. Once a rate increase application is filed with the PPUC, the ensuing administrative and hearing process may be lengthy and costly. The timing of our rate increase requests is therefore dependent upon the estimated cost of the administrative process in relation to the investments and expenses that we hope to recover through the rate increase. In addition, the amount or frequency of rate increases may be decreased or lengthened as a result of changes in income tax laws regarding tax-basis depreciation as it applies to our capital expenditures or qualifying repair tax deductible expenditures, and by changes to income tax rates.

We can provide no assurances that future requests will be approved by the PPUC; and, if approved, we cannot guarantee that these rate increases will be granted in a timely or sufficient manner to cover the investments and expenses for which we sought the rate increase. If we are unable to obtain PPUC approval of our requests for rate increases, or if approved rate increases are untimely or inadequate to cover our investments in utility plant and equipment and projected expenses, our results of operations may be adversely affected.

We are subject to federal, state and local regulation that may impose costly limitations and restrictions on the way we do business.

Various federal, state and local authorities regulate many aspects of our business. Among the most important of these regulations are those relating to the quality of water we supply our customers, water allocation rights and the quality of the effluent we discharge from our wastewater treatment facilities. Government authorities continually review these regulations, particularly the drinking water quality regulations, and may propose new or more restrictive requirements in the future. We are required to perform water and wastewater quality tests that are monitored by the PPUC, the U.S. Environmental Protection Agency, or EPA, and the Pennsylvania Department of Environmental Protection, or DEP, for the detection of certain chemicals and compounds in our water and effluent. If new or more restrictive limitations on permissible levels of substances and contaminants in our water and wastewater are imposed, we may not be able to adequately predict the costs necessary to meet regulatory standards. If we are unable to recover the cost of implementing new water and wastewater treatment procedures in response to more restrictive quality regulations through our rates that we charge our customers, or if we fail to comply with such regulations, it could have a material adverse effect on our financial condition and results of operations.

We are also subject to water allocation regulations that control the amount of water that we can draw from water sources. The Susquehanna River Basin Commission, or SRBC, and the DEP regulate the amount of water withdrawn from streams in the watershed for water supply purposes to assure that sufficient quantities are available to meet our needs and the needs of other regulated users. In addition, government drought restrictions could cause the SRBC or the DEP to temporarily reduce the amount of our allocations. If new or more restrictive water allocation regulations are implemented or our allocations are reduced due to weather conditions, it may have an adverse effect on our ability to supply the demands of our customers, and in turn, on our revenues and results of operations.

S-7

TABLE OF CONTENTS

Our business is subject to seasonal fluctuations, which could affect demand for our water service and our revenues.

Demand for our water during the warmer months is generally greater than during cooler months due primarily to additional requirements for water in connection with cooling systems, swimming pools, irrigation systems and other outside water use. Throughout the year, and particularly during typically warmer months, demand will vary with temperature and rainfall levels. If temperatures during the typically warmer months are cooler than expected, or there is more rainfall than expected, the demand for our water may decrease and adversely affect our revenues.

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

We depend on an adequate water supply to meet the present and future demands of our customers and to continue our expansion efforts. Unexpected conditions may interfere with our water supply sources. Drought and overuse may limit the availability of surface and ground water. These factors might adversely affect our ability to supply water in sufficient quantities to our customers and our revenues and earnings may be adversely affected. Additionally, cool and wet weather, as well as drought restrictions and our customers’ conservation efforts, may reduce consumption demands, also adversely affecting our revenue and earnings. Furthermore, freezing weather may also contribute to water transmission interruptions caused by pipe and main breakage. If we experience an interruption in our water supply, it could have a material adverse effect on our financial condition and results of operations.

The necessity for increased security has and may continue to result in increased operating costs.

We have taken steps to increase security measures at our facilities and heighten employee awareness of threats to our water supply. We have also tightened our security measures regarding the delivery and handling of certain chemicals used in our business. We have and will continue to bear increased costs for security precautions to protect our facilities, operations and supplies. We are not aware of any specific threats to our facilities, operations or supplies. However, it is possible that we would not be in a position to control the outcome of such events should they occur.

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

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 on entities around the world have caused operational failures and/or compromised corporate and personal data. Such 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 regulation, including standards for drinking water, litigation and reputational damage.

We depend significantly on the services of the members of our senior management team, and the departure of any of those persons could cause our operating results to suffer.

Our success depends significantly on the continued individual and collective contributions of our senior management team. If we lose the services of any member of our senior management or are unable to hire and retain experienced management personnel, our operating results could suffer.

Work stoppages and other labor relations matters could adversely affect our operating results.

Approximately one-third of our workforce is unionized under a contract with a labor union. In light of rising costs for healthcare and retirement benefits, contract negotiations in the future may be difficult. We are subject to

S-8

TABLE OF CONTENTS

a risk of work stoppages and other labor actions as we negotiate with the union to address these issues, which could affect our business, financial condition, and results of operations. Although we believe we have a good relationship with our union workforce and have a strike contingency plan, we cannot be assured that issues with our labor force will be resolved favorably to us in the future or that we will not experience work stoppages.

The failure of, or the requirement to repair, upgrade or dismantle, either of our dams may adversely affect our financial condition and results of operations.

Our water system includes two impounding dams. While we maintain active and robust dam maintenance and inspection programs, a failure of the dams could result in injuries and damage to residential and/or commercial property downstream for which we may be responsible, in whole or in part. The failure of a dam could also adversely affect our ability to supply water in sufficient quantities to our customers and could adversely affect our financial condition and results of operations. We carry liability insurance on our dams, however, our limits may not be sufficient to cover all losses or liabilities incurred due to the failure of one of our dams. The estimated costs to maintain and upgrade our dams are included in our capital budget. Although such costs have previously been recoverable in rates, there is no guarantee that these costs will continue to be recoverable and in what magnitude they will be recoverable.

Wastewater operations entail significant risks and may impose significant costs.

Wastewater collection and treatment and septage pumping and sludge hauling involve various unique risks. If collection or treatment systems fail or do not operate properly, or if there is a spill, untreated or partially treated wastewater could discharge onto property or into nearby streams and rivers, causing various damages and injuries, including environmental damage. These risks are most acute during periods of substantial rainfall or flooding, which are the main causes of sewer overflow and system failure. Liabilities resulting from such damages and injuries could materially and adversely affect our business, financial condition, and results of operations.

Financial, Economic and Market Related Risks

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

A general economic downturn may lead to a number of impacts on our business that may affect our financial condition and results of operations. Such impacts may include: a reduction in discretionary and recreational water use by our residential water customers, particularly during the summer months when such discretionary usage is normally at its highest; a decline in usage by industrial and commercial customers as a result of decreased business activity; an increased incidence of customers’ inability to pay or delays in paying their utility bills, or an increase in customer bankruptcies, which may lead to higher bad debt expense and reduced cash flow; a lower customer growth rate due to a decline in new housing starts; and a decline in the number of active customers due to housing vacancies or abandonments. A deterioration in general economic conditions may also lead to an investment market downturn, which may result in our pension plans’ asset market values suffering a decline and significant volatility. A decline in our pension plans’ asset market values could increase our required cash contributions to these plans and pension expense in subsequent years.

The current concentration of our business in central and southern Pennsylvania makes us particularly susceptible to adverse developments in local economic and demographic conditions.

Our service territory presently includes 51 municipalities within three counties in south-central Pennsylvania. Our revenues and operating results are therefore especially subject to local economic and demographic conditions in the area. A change in any of these conditions could make it more costly or difficult for us to conduct our business. In addition, any such change would have a disproportionate effect on us, compared to water and wastewater utility companies that do not have such a geographic concentration.

We depend on the availability of capital for expansion, construction and maintenance.

Our ability to continue our expansion efforts and fund our construction and maintenance program depends on the availability of adequate capital. There is no guarantee that we will be able to obtain sufficient capital in the future or that the cost of capital will not be too high for future expansion and construction. In addition, approval from the PPUC must be obtained prior to our sale and issuance of securities. If we are unable to obtain

S-9

TABLE OF CONTENTS

approval from the PPUC on these matters, or to obtain approval in a timely manner, it may affect our ability to effect transactions that are beneficial to us or our shareholders. A single transaction may itself not be profitable but might still be necessary to continue providing service or to grow the business.

The failure to maintain our existing credit rating could affect our cost of funds and related liquidity.

Standard & Poor's Ratings Services rates our outstanding debt and has given a credit rating to us. Their evaluations are based on a number of factors, which include financial strength as well as transparency with rating agencies and timeliness of financial reporting. Failure to maintain our current credit rating could adversely affect our cost of funds and related liquidity.

We may face competition from other water suppliers or wastewater service providers that may hinder our growth and reduce our profitability.

We face competition from other water suppliers for acquisitions, which may limit our growth opportunities. Furthermore, even after we have been the successful bidder in an acquisition, competing water suppliers or wastewater service providers may challenge our application for extending our franchise territory to cover the target company’s market. Finally, third parties either supplying water on a contract basis to municipalities or entering into agreements to operate municipal water or wastewater systems might adversely affect our business by winning contracts that may be beneficial to us. If we are unable to compete successfully with other water suppliers and wastewater service providers for these acquisitions, franchise territories and contracts, it may impede our expansion goals and adversely affect our profitability.

An important element of our growth strategy is the acquisition of water and wastewater systems. Any pending or future acquisitions we decide to undertake will involve risks.

The acquisition and integration of water and wastewater systems is an important element in our growth strategy. This strategy depends on identifying suitable acquisition opportunities and reaching mutually agreeable terms with acquisition candidates. The negotiation of potential acquisitions as well as the integration of acquired businesses could require us to incur significant costs. Further, acquisitions may result in dilution for the owners of our common stock, our incurrence of debt and contingent liabilities and fluctuations in quarterly results. In addition, the businesses and other assets we acquire may not achieve the financial results that we expect, which could adversely affect our profitability.

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

The terms of our debt instruments impose conditions on our ability to pay dividends. We have paid dividends on our common stock each year since our inception in 1816 and have increased the amount of dividends paid each year since 1997. 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 on our common stock and the amount of those dividends. There can be no assurance that 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 that our cash generated from operations, and, if necessary, borrowings under our 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 refinance our obligations or sell additional equity, which may be on terms that are not as favorable to us. 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 acceptable 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.

TABLE OF CONTENTS

There is a limited trading market for our common stock; you may not be able to resell your shares at or above the price you pay for them.

Although our common stock is listed for trading on the NASDAQ Global Select Market, the trading in our common stock has substantially less liquidity than many other companies quoted on the NASDAQ Global Select Market. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the market of willing buyers and sellers of our common stock at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which we have no control. Because of the limited volume of trading in our common stock, a sale of a significant number of shares of our common stock in the open market could cause our stock price to decline.

The final determination of our income tax liability may be materially different from our income tax provision.

Significant judgment is required in determining our provision for income taxes. The calculation of the provision for income taxes is subject to our interpretation of applicable business tax laws in the federal and state jurisdictions in which we file. In addition, our income tax returns are subject to periodic examination by the Internal Revenue Service, or IRS, and other taxing authorities.

In December 2014, we changed our tax method of accounting to permit the expensing of qualifying asset improvement costs that were previously being capitalized and depreciated for tax purposes. Our determination of what qualifies as a capital cost versus a repair expense tax deduction is subject to subsequent adjustment and may impact the income tax benefits that have been recognized.

Although we believe our income tax estimates are appropriate, there is no assurance that the final determination of our income tax liability will not be materially different, either higher or lower, from what is reflected in our income tax provision. In the event we are assessed additional income taxes, our business, financial condition, and results of operations could be adversely affected.

We are subject to market and interest rate risk on our $12,000,000 variable interest rate debt issue.

We are subject to interest rate risk in conjunction with our $12,000,000 variable interest rate debt issue. This exposure, however, has been hedged with an interest rate swap. This hedge will protect the Company from the risk of changes in the benchmark interest rates but does not protect the Company’s exposure to the changes in the difference between its own variable funding rate and the benchmark rate. A breakdown of the historical relationships between the cost of funds of the Company and the benchmark rate underlying the interest rate swap could result in higher interest rates adversely affecting our financial results.

The holders of the $12,000,000 variable rate Pennsylvania Economic Development Financing Authority (PEDFA) Series A Bonds may tender their bonds at any time. When the bonds are tendered, they are subject to an annual remarketing agreement, pursuant to which a remarketing agent attempts to remarket the tendered bonds pursuant to the terms of the Indenture. In order to keep variable interest rates down and to enhance the marketability of the Series A Bonds, the Company entered into a Reimbursement, Credit and Security Agreement with PNC Bank, National Association (“the Bank”) dated as of May 1, 2008. This agreement provides for a direct pay letter of credit issued by the Bank to the trustee for the Series A Bonds. The letter of credit expires June 30, 2023 and is reviewed annually for a potential extension of the expiration date. The Bank is responsible for providing the trustee with funds for the timely payment of the principal and interest on the Series A Bonds and for the purchase price of the Series A Bonds that have been tendered or deemed tendered for purchase and have not been remarketed. If the Bank is unable to meet its obligations, the Company would be required to buy any bonds which had been tendered.

Risks Related to Health, Safety and Environmental Concerns

Some scientific experts are predicting a worsening of weather volatility in the future, possibly created by the climate change greenhouse gases. Changing severe weather patterns could require additional expenditures to reduce the risk associated with any increasing storm, flood and drought occurrences.

The issue of climate change continues to receive attention worldwide. Many climate change predictions, if true, present several potential challenges to water and wastewater utilities, such as increased frequency and duration of droughts, increased precipitation and flooding, potential degradation of water quality, and the

S-11

TABLE OF CONTENTS

resulting changes in demand for services. The changes may result in lower revenue, the need for additional capital expenditures, or increased costs. Because of the uncertainty of weather volatility related to climate change, we cannot predict its potential impact on our business, financial condition, or results of operations. Although any potential expenditures and costs may be recovered in the form of higher rates, there can be no assurance that the PPUC would approve rate increases to enable us to recover such expenditures and costs. We cannot assure you that our costs of complying with any climate change related measures will not harm our business, financial condition, or results of operations.

Contamination of our water supply may cause disruption in our services and adversely affect our revenues.

Our water supply is subject to contamination from the migration of naturally-occurring substances in groundwater and surface systems and pollution resulting from man-made sources. In the event that our water supply is contaminated, we may have to interrupt the use of that water supply until we are able to substitute the flow of water from an uncontaminated water source through our interconnected transmission and distribution facilities. In addition, we may incur significant costs in order to treat the contaminated source through expansion of our current treatment facilities or development of new treatment methods. Our inability to substitute water supply from an uncontaminated water source, or to adequately treat the contaminated water source in a cost-effective manner, may have an adverse effect on our revenues.

If our sources of water or water at customer sites become contaminated, it could subject us to reduction in usage, regulatory actions, damage to our reputation and private litigation.

Our primary business is to impound, purify to meet or exceed safe drinking water standards and distribute water. Contamination of the water provided to our customers exposes us to risks, including regulatory or government action, customer exposure to contamination or hazardous substances in the water, and resulting private claims and litigation. Negative impacts to our reputation may occur even if we are not responsible for any contamination or its consequences. Pending or future claims against us and reputational damage could have a material adverse impact on our business, financial condition, and results of operations.

The Novel Coronavirus (COVID-19) pandemic and the attempt to contain it may harm our business, results of operations, financial condition and liquidity.

On March 13, 2020, the United States declared the COVID-19 pandemic a national emergency. The impact that COVID-19 will have on the Company, our customers and our vendors prospectively depends on numerous uncertainties, including the severity and duration of the pandemic, sufficiency of the government’s vaccination program and actions which could potentially be taken by federal or state governmental and/or regulatory authorities and could have an adverse effect on the Company’s business, results of operations, financial condition, and liquidity.

MATERIAL UNITED STATES FEDERAL INCOME

AND ESTATE TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following is a summary of material United States federal income and estate tax consequences of the purchase, ownership and disposition of York Water Common Stock as of the date hereof. Except where noted, this summary deals only with common stock that is held as a capital asset (generally, property held for investment) by a non-U.S. holder (as defined below).

A “non-U.S. holder” means a beneficial owner of York Water Common Stock (other than an entity treated as a partnership for United States federal income tax purposes) that is not, for United States federal income tax purposes, any of the following:

•	an individual citizen or resident of the United States;

•	a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•	an estate the income of which is subject to United States federal income taxation regardless of its source; or

•

a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income and estate tax consequences different from those summarized below. This summary does not address all aspects of United States federal income and estate taxes and does not deal with non-U.S., state, local or other tax considerations that may be relevant to non-U.S. holders in light of their particular circumstances. In addition, it does not represent a detailed description of the United States federal income and estate tax consequences applicable to non-U.S. holders that are subject to special treatment under the United States federal income tax laws, including, without limitation:

•	United States expatriates;

•	foreign pension funds;

•	“controlled foreign corporations” and “passive foreign investment companies”;

•	a partnership or other pass-through entity for United States federal income tax purposes (and investors therein);

•	persons subject to the alternative minimum tax;

•	persons holding York Water Common Stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

•	banks, insurance companies, and other financial institutions;

•	brokers, dealers or traders in securities;

•	tax-exempt organizations or governmental organizations;

•	persons deemed to sell York Water Common Stock under the constructive sale provisions of the Code; and

•	persons subject to special tax accounting rules as a result of any item of gross income with respect to York Water Common Stock being taken into account in an applicable financial statement.

S-15

TABLE OF CONTENTS

We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below.

If a partnership (or other entity treated as a partnership for United States federal income tax purposes) holds York Water Common Stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding York Water Common Stock, you should consult your tax advisors.

If you are considering the purchase of York Water Common Stock, you should consult your own tax advisors concerning the particular United States federal income and estate tax consequences to you of the purchase, ownership and disposition of York Water Common Stock, as well as the consequences to you arising under other United States federal tax laws and the laws of any other taxing jurisdiction.

Dividends

In the event that we make a distribution of cash or other property (other than certain pro rata distributions of our stock) in respect of York Water Common Stock, the distribution generally will be treated as a dividend for United States federal income tax purposes to the extent it is paid from our current or accumulated earnings and profits, as determined under United States federal income tax principles. Any portion of a distribution that exceeds our current and accumulated earnings and profits generally will be treated first as a tax-free return of capital, causing a reduction in the adjusted tax basis of a non-U.S. holder’s common stock, and to the extent the amount of the distribution exceeds a non-U.S. holder’s adjusted tax basis in York Water Common Stock, the excess will be treated as gain from the disposition of York Water Common Stock (the tax treatment of which is discussed below under “Gain on Disposition of Common Stock”).

Dividends paid to a non-U.S. holder generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, are attributable to a United States permanent establishment) are not subject to the withholding tax, provided certain certification and disclosure requirements are satisfied. Instead, such dividends are subject to United States federal income tax on a net income basis in the same manner as if the non-U.S. holder were a United States person as defined under the Code. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

A non-U.S. holder who wishes to claim the benefit of an applicable treaty rate and avoid backup withholding, as discussed below, for dividends will be required (a) to provide the applicable withholding agent with a properly executed Internal Revenue Service (“IRS”) Form W-8BEN or Form W-8BEN-E (or other applicable form) certifying under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if York Water Common Stock is held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable United States Treasury regulations, including the provision of a properly executed Form W-8IMY. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals.

A non-U.S. holder eligible for a reduced rate of United States federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Gain on Disposition of Common Stock

Subject to the discussion of backup withholding below, any gain realized by a non-U.S. holder on the sale or other disposition of York Water Common Stock generally will not be subject to United States federal income tax unless:

•	the gain is effectively connected with a trade or business of the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of the non-U.S. holder);

S-16

TABLE OF CONTENTS

•	the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or

•	we are or have been a “United States real property holding corporation” for United States federal income tax purposes and certain other conditions are met.

A non-U.S. holder described in the first bullet point immediately above will be subject to tax on the gain derived from the sale or other disposition in the same manner as if the non-U.S. holder were a United States person as defined under the Code. In addition, if any non-U.S. holder described in the first bullet point immediately above is a foreign corporation, the gain realized by such non-U.S. holder may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a 30% (or such lower rate as may be specified by an applicable income tax treaty) tax on the gain derived from the sale or other disposition, which gain may be offset by United States source capital losses even though the individual is not considered a resident of the United States.

Generally, a corporation is a “United States real property holding corporation” if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business (all as determined for United States federal income tax purposes). We have not determined whether we are a “United States real property holding corporation” for United States federal income tax purposes. We can give no assurance that we are not or will not become one in the future. If we are or become a “United States real property holding corporation,” so long as York Water Common Stock is regularly traded on an established securities market during the calendar year in which the sale or other disposition occurs, only a non-U.S. holder who holds or held (at any time during the shorter of the five year period preceding the date of disposition or the holder’s holding period) more than 5% of York Water Common Stock will be subject to United States federal income tax on the gain derived from the sale or other disposition of York Water Common Stock in the same manner as if the non-U.S. holder were a United States person as defined in the Code. Certain attribution rules are applicable in determining whether the 5% ownership threshold described above is exceeded.

Federal Estate Tax

Common stock held by an individual non-U.S. holder at the time of death will be included in such holder’s gross estate for United States federal estate tax purposes and may give rise to United States federal estate tax, unless an applicable estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

Distributions paid to a non-U.S. holder and the amount of any tax withheld with respect to such distributions generally will be reported to the IRS. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

A non-U.S. holder will not be subject to backup withholding on dividends received if such holder certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that such holder is a United States person as defined under the Code), or such holder otherwise establishes an exemption (though such holder may be subject to the general dividend withholding tax discussed above in “Dividends”).

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other disposition of York Water Common Stock made within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code), or such owner otherwise establishes an exemption.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder’s United States federal income tax liability provided the required information is timely furnished to the IRS.

S-17

TABLE OF CONTENTS

Additional Withholding Requirements

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% United States federal withholding tax may apply to any dividends paid on York Water Common Stock to (1) a “foreign financial institution” (as specifically defined in the Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (a) an exemption from FATCA, or (b) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (2) a “non-financial foreign entity” (as specifically defined in the Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (a) an exemption from FATCA, or (b) adequate information regarding certain substantial United States beneficial owners of such entity (if any). If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “Dividends,” the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. You should consult your own tax advisors regarding these requirements and whether they may be relevant to your ownership and disposition of York Water Common Stock.

TABLE OF CONTENTS

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase of shares of York Water Common Stock by (i) employee benefit plans that are subject to Title I of ERISA, (ii) plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code or provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”), and (iii) entities which are deemed to hold the assets of any of the foregoing types of plans, accounts or arrangements (each of the foregoing described in clauses (i), (ii), and (iii) being referred to herein as a “Plan”).

General Fiduciary Matters and Prohibited Transaction Issues

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (a “Covered Plan”) and prohibit certain transactions involving the assets of a Covered Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such a Covered Plan or the management or disposition of the assets of such a Covered Plan, or who renders investment advice for a fee or other compensation to such a Covered Plan, is generally considered to be a fiduciary of the Covered Plan.

Section 406 of ERISA and Section 4975 of the Code prohibit Covered Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code. ERISA and the Code contain certain exemptions from the prohibited transactions described above, and the Department of Labor has issued several exemptions, although certain exemptions do not provide relief from the prohibitions on self-dealing contained in Section 406(b) of ERISA and Sections 4975(c)(1)(E) and (F) of the Code. Exemptions include Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code pertaining to certain transactions with non-fiduciary service providers; Department of Labor Prohibited Transaction Class Exemption 95-60, which we refer to as a “PTCE,” applicable to transactions involving insurance company general accounts; PTCE 90-1, regarding investments by insurance company pooled separate accounts; PTCE 91-38, regarding investments by bank collective investment funds; PTCE 84-14, regarding investments effected by a qualified professional asset manager; and PTCE 96-23, regarding investments effected by an in-house asset manager. There can be no assurance that any of these exemptions will be available with respect to an investment in York Water Common Stock. A party in interest or disqualified person who engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the Covered Plan that engaged in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code and the transactions may have to be rescinded.

In considering an investment in York Water Common Stock with a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duty to the Plan, including without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Government plans, foreign plans and certain church plans, while not subject to the fiduciary responsibility provisions of Title I of ERISA or the prohibited transaction provisions of Section 406 of ERISA or Section 4975 of the Code, may nevertheless be subject to Similar Laws. Fiduciaries of such Plans should consult with their counsel before acquiring shares of York Water Common Stock.

The foregoing discussion is general in nature and is not intended to be all-inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering purchasing shares of York Water Common Stock on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code or any Similar Law and whether an exemption would be required. Neither this discussion nor anything provided in this prospectus is, or is intended to be, investment advice directed at any potential Plan purchasers, or at Plan purchasers generally, and such purchasers of shares of York Water Common Stock should consult and rely on their own counsel and advisers as to whether an investment in shares of York Water Common Stock is suitable for the Plan. The sale of shares of York Water Common Stock to any Plan is in no respect a representation by us, an underwriter or any of our or their affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by Plans generally or any particular Plan, or that such investment is prudent or appropriate for plans generally or any particular Plan.

Stabilization and Short Positions

In connection with this offering, the underwriter may effect certain transactions in shares of York Water Common Stock in the open market in order to prevent or retard a decline in the market price of York Water Common Stock while this offering is in progress. These transactions may include short sales, purchases to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriter of a greater number of shares than it is required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. “Covered” shorts are short positions in an amount not greater than the underwriter’s option described herein, and “naked” shorts are short positions in excess of that amount. In determining the source of shares to close out a “covered” short, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option. A “covered” short may be covered by either exercising the underwriter’s option or purchasing shares in the open market. A “naked” short is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of York Water Common Stock in the open market prior to the completion of the offering, and may only be closed out by purchasing shares in the open market. Stabilizing transactions consist of various bids for or purchases of York Water Common Stock made by the underwriter in the open market prior to the completion of the offering.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriter for its own account, may have the effect of preventing or slowing a decline in the market price of York Water Common Stock and may stabilize, maintain or otherwise affect the market price of York Water Common Stock. As a result, the price of York Water Common Stock may be higher than the price that might otherwise exist in the open market. If these activities are commenced by the underwriter, they may be discontinued at any time. These transactions may be effected on the Nasdaq Global Select Market, in the over-the-counter market or otherwise.

Electronic Distribution

In connection with this offering, the underwriter may distribute prospectuses by electronic means, such as email. In addition, the underwriter may facilitate Internet distribution for this offering to certain of its Internet subscription customers, and allocate a limited number of shares for sale to its online brokerage customers. A prospectus in electronic format is being made available on the website maintained by the underwriter. Other than the prospectus in electronic format, the information on the underwriter’s website and any information contained in any other website maintained by the underwriter is not a part of the prospectus or the registration statement, of which this prospectus supplement forms a part.

ABOUT THE YORK WATER COMPANY

We were organized under the laws of the Commonwealth of Pennsylvania in 1816 and are the oldest investor-owned water utility in the United States. Our primary business of the Company is to impound, purify to meet or exceed safe drinking water standards and distribute water. We also own and operate two wastewater collection systems and five wastewater collection and treatment systems. We operate within our franchised water and wastewater territory, which covers portions of 51 municipalities within three counties in south-central Pennsylvania. We are regulated by the Pennsylvania Public Utility Commission, or PPUC, for both water and wastewater in the areas of billing, payment procedures, dispute processing, terminations, service territory, debt and equity financing and rate setting. We must obtain PPUC approval before changing any practices associated with the aforementioned areas.

Water service is supplied through our own distribution system. We obtain the bulk of our water supply from both the South Branch and East Branch of the Codorus Creek, which together have an average daily flow of 73.0 million gallons. This combined watershed area is approximately 117 square miles. We have two reservoirs, Lake Williams and Lake Redman, which together hold up to approximately 2.2 billion gallons of water. We supplement our reservoirs with a 15-mile pipeline from the Susquehanna River to Lake Redman which provides access to an additional supply of 12.0 million gallons of untreated water per day. We also own nine wells which are capable of providing a safe yield of approximately 597,000 gallons per day to supply water to the customers of our satellite systems in Adams County. As of June 30, 2021, our average daily availability was 35.6 million gallons, and average daily consumption was approximately 20.2 million gallons. Our service territory had an estimated population of 202,000 as of December 31, 2020. Industry within our service territory is diversified, manufacturing such items as fixtures and furniture, electrical machinery, food products, paper, ordnance units, textile products, air conditioning systems, laundry detergent, barbells, and motorcycles.

Our principal executive offices are located at 130 East Market Street, York, Pennsylvania 17401. Our telephone number is (717) 845-3601. Our website address is www.yorkwater.com.

TABLE OF CONTENTS

RISK FACTORS

Investing in the securities described herein involves risk. We urge you to carefully consider the risk factors described below.

The rates we charge our customers are subject to regulation. If we are unable to obtain government approval of our requests for rate increases, or if approved rate increases are untimely or inadequate to cover our investments in utility plant and equipment and projected expenses, our results of operations may be adversely affected.

Our ability to maintain and meet our financial objectives is dependent upon the rates we charge our customers, which are subject to approval by the PPUC. We file rate increase requests with the PPUC, from time to time, to recover our investments in utility plant and equipment and projected expenses. Any rate increase or adjustment must first be justified through documented evidence and testimony. The PPUC determines whether the investments and expenses are recoverable, the length of time over which such costs are recoverable, or, because of changes in circumstances, whether a remaining balance of deferred investments and expenses is no longer recoverable in rates charged to customers. Once a rate increase application is filed with the PPUC, the ensuing administrative and hearing process may be lengthy and costly. The timing of our rate increase requests is therefore dependent upon the estimated cost of the administrative process in relation to the investments and expenses that we hope to recover through the rate increase. In addition, the amount or frequency of rate increases may be decreased or lengthened as a result of changes in income tax laws regarding tax-basis depreciation as it applies to our capital expenditures or qualifying repair tax deductible expenditures, and by changes to income tax rates.

We can provide no assurances that future requests will be approved by the PPUC; and, if approved, we cannot guarantee that these rate increases will be granted in a timely or sufficient manner to cover the investments and expenses for which we sought the rate increase. If we are unable to obtain PPUC approval of our requests for rate increases, or if approved rate increases are untimely or inadequate to cover our investments in utility plant and equipment and projected expenses, our results of operations may be adversely affected.

We are subject to federal, state and local regulation that may impose costly limitations and restrictions on the way we do business.

Various federal, state and local authorities regulate many aspects of our business. Among the most important of these regulations are those relating to the quality of water we supply our customers, water allocation rights and the quality of the effluent we discharge from our wastewater treatment facilities. Government authorities continually review these regulations, particularly the drinking water quality regulations, and may propose new or more restrictive requirements in the future. We are required to perform water and wastewater quality tests that are monitored by the PPUC, the U.S. Environmental Protection Agency, or EPA, and the Pennsylvania Department of Environmental Protection, or DEP, for the detection of certain chemicals and compounds in our water and effluent. If new or more restrictive limitations on permissible levels of substances and contaminants in our water and wastewater are imposed, we may not be able to adequately predict the costs necessary to meet regulatory standards. If we are unable to recover the cost of implementing new water and wastewater treatment procedures in response to more restrictive quality regulations through our rates that we charge our customers, or if we fail to comply with such regulations, it could have a material adverse effect on our financial condition and results of operations.

We are also subject to water allocation regulations that control the amount of water that we can draw from water sources. The Susquehanna River Basin Commission, or SRBC, and the DEP regulate the amount of water withdrawn from streams in the watershed for water supply purposes to assure that sufficient quantities are available to meet our needs and the needs of other regulated users. In addition, government drought restrictions could cause the SRBC or the DEP to temporarily reduce the amount of our allocations. If new or more restrictive water allocation regulations are implemented or our allocations are reduced due to weather conditions, it may have an adverse effect on our ability to supply the demands of our customers, and in turn, on our revenues and results of operations.

Our business is subject to seasonal fluctuations, which could affect demand for our water service and our revenues.

Demand for our water during the warmer months is generally greater than during cooler months due primarily to additional requirements for water in connection with cooling systems, swimming pools, irrigation

3

TABLE OF CONTENTS

systems and other outside water use. Throughout the year, and particularly during typically warmer months, demand will vary with temperature and rainfall levels. If temperatures during the typically warmer months are cooler than expected, or there is more rainfall than expected, the demand for our water may decrease and adversely affect our revenues.

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

We depend on an adequate water supply to meet the present and future demands of our customers and to continue our expansion efforts. Unexpected conditions may interfere with our water supply sources. Drought and overuse may limit the availability of surface and ground water. These factors might adversely affect our ability to supply water in sufficient quantities to our customers and our revenues and earnings may be adversely affected. Additionally, cool and wet weather, as well as drought restrictions and our customers’ conservation efforts, may reduce consumption demands, also adversely affecting our revenue and earnings. Furthermore, freezing weather may also contribute to water transmission interruptions caused by pipe and main breakage. If we experience an interruption in our water supply, it could have a material adverse effect on our financial condition and results of operations.

Some scientific experts are predicting a worsening of weather volatility in the future, possibly created by the climate change greenhouse gases. Changing severe weather patterns could require additional expenditures to reduce the risk associated with any increasing storm, flood and drought occurrences.

The issue of climate change continues to receive attention worldwide. Many climate change predictions, if true, present several potential challenges to water and wastewater utilities, such as increased frequency and duration of droughts, increased precipitation and flooding, potential degradation of water quality, and the resulting changes in demand for services. The changes may result in lower revenue, the need for additional capital expenditures, or increased costs. Because of the uncertainty of weather volatility related to climate change, we cannot predict its potential impact on our business, financial condition, or results of operations. Although any potential expenditures and costs may be recovered in the form of higher rates, there can be no assurance that the PPUC would approve rate increases to enable us to recover such expenditures and costs. We cannot assure you that our costs of complying with any climate change related measures will not harm our business, financial condition, or results of operations.

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

A general economic downturn may lead to a number of impacts on our business that may affect our financial condition and results of operations. Such impacts may include: a reduction in discretionary and recreational water use by our residential water customers, particularly during the summer months when such discretionary usage is normally at its highest; a decline in usage by industrial and commercial customers as a result of decreased business activity; an increased incidence of customers’ inability to pay or delays in paying their utility bills, or an increase in customer bankruptcies, which may lead to higher bad debt expense and reduced cash flow; a lower customer growth rate due to a decline in new housing starts; and a decline in the number of active customers due to housing vacancies or abandonments. A deterioration in general economic conditions may also lead to an investment market downturn, which may result in our pension plans’ asset market values suffering a decline and significant volatility. A decline in our pension plans’ asset market values could increase our required cash contributions to these plans and pension expense in subsequent years.

The current concentration of our business in central and southern Pennsylvania makes us particularly susceptible to adverse developments in local economic and demographic conditions.

Our service territory presently includes 51 municipalities within three counties in south-central Pennsylvania. Our revenues and operating results are therefore especially subject to local economic and demographic conditions in the area. A change in any of these conditions could make it more costly or difficult for us to conduct our business. In addition, any such change would have a disproportionate effect on us, compared to water and wastewater utility companies that do not have such a geographic concentration.

Contamination of our water supply may cause disruption in our services and adversely affect our revenues.

Our water supply is subject to contamination from the migration of naturally-occurring substances in groundwater and surface systems and pollution resulting from man-made sources. In the event that our water

4

TABLE OF CONTENTS

supply is contaminated, we may have to interrupt the use of that water supply until we are able to substitute the flow of water from an uncontaminated water source through our interconnected transmission and distribution facilities. In addition, we may incur significant costs in order to treat the contaminated source through expansion of our current treatment facilities or development of new treatment methods. Our inability to substitute water supply from an uncontaminated water source, or to adequately treat the contaminated water source in a cost-effective manner, may have an adverse effect on our revenues.
