We discuss in this prospectus supplement, the accompanying prospectus and in documents that we have incorporated into this prospectus by reference certain matters which are not historical facts, but which are “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Words such as “may,” “should,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan” and similar expressions are intended to identify “forward-looking statements.” We intend these forward-looking statements to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this prospectus supplement, the accompanying prospectus and the documents that we incorporate by reference, and in particular those factors referenced in the “Risk Factors” sections in this prospectus supplement, the accompanying prospectus and the documents we incorporate by reference. These forward-looking statements include, but are not limited to statements regarding:

These forward-looking statements reflect what the Company currently anticipates will happen. What actually happens could differ materially from what it currently anticipates will happen. The Company does not intend to make a public announcement when forward-looking statements in this prospectus supplement are no longer accurate, whether as a result of new information, what actually happens in the future or for any other reason. Important matters that may affect what will actually happen include, but are not limited to:

These forward-looking statements are neither promises nor guarantees of future performance due to a variety of risks and uncertainties, many of which are beyond our control, which could cause actual results to differ materially from those indicated by these forward-looking statements, as well as those risks more fully discussed in the sections of this prospectus supplement and the accompanying prospectus entitled “Risk Factors” and the risk factors and cautionary statements described in other documents that we file from time to time with the SEC, including in our most recent Annual Report on Form 10-K for the year ended December 31, 2021.

Given these uncertainties, readers should not place undue reliance on our forward-looking statements. These forward-looking statements speak only as of the date on which such statements were made and are not guarantees of future performance. Except as may be required by applicable law, we do not undertake to update any forward-looking statements after the date of this prospectus or the respective dates of documents incorporated by reference herein or therein that include forward-looking statements.

Investing in York Water Common Stock involves risks. You should review and carefully consider the risks, uncertainties and other factors described below and all of the information included elsewhere in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein before deciding to invest in the shares of York Water Common Stock. We also urge you to consider carefully the risks, uncertainties and other factors set forth under the heading “Cautionary Note Regarding Forward-Looking Statements”. However, additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business, operations, financial condition and financial results and the value of the York Water Common Stock. The risk factors set forth in this prospectus supplement replace the risk factors set forth in the accompanying prospectus in their entirety.

The price of York Water Common Stock may be volatile. This volatility may affect the price at which you could sell York Water Common Stock, and the sale or resale of substantial amounts of York Water Common Stock could adversely affect the market price of York Water Common Stock. The market price for York Water Common Stock has historically experienced, and may continue to experience, volatility. This volatility may affect the price at which you could sell York Water Common Stock, and the sale or issuance of substantial amounts of York Water Common Stock, or the perception that such sales or issuances could occur, could adversely affect the market price of York Water Common Stock. In addition, the availability for sale of substantial amounts of York Water Common Stock could adversely impact its market price. The issuance or sale of shares of York Water Common Stock, or the perception that such issuances or sales could occur, could adversely affect the market price of York Water Common Stock, even if our business is doing well. Any of the foregoing may also impair our ability to raise additional capital through the sale of shares of York Water Common Stock. The market price of York Water Common Stock may be influenced by many factors, some of which are beyond our control, including the factors discussed above under “Cautionary Note Regarding Forward-Looking Statements” or elsewhere in the accompanying prospectus and the documents incorporated by reference herein and therein and include the following:

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

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.

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.

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.

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.

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.

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 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.

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.

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

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.

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 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.

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.

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.

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

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.

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 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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

We will receive approximately $     million in net proceeds from the sale of the shares of York Water Common Stock we are offering pursuant to this prospectus supplement, after deducting an aggregate of approximately $     in underwriting discounts and commissions and estimated offering expenses. If the underwriter’s option is exercised in full, we estimate that our net proceeds will be approximately $     million.

We expect to use all of the net proceeds from this offering for general corporate purposes, including our capital investment program, repayment of outstanding indebtedness, and potential acquisitions.

The following table sets forth, as of December 31, 2021, our capitalization on an actual basis and on an as adjusted basis to give effect to the sale of the shares of Common Stock in this offering. This table should be read in conjunction with our Financial Statements and the Notes to Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2021, which are incorporated by reference herein.

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:

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:

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.

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.

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:

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.

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.

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.

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.

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”).

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.

Accordingly, by its acceptance of shares of York Water Common Stock, each purchaser and subsequent transferee will be deemed to have represented and warranted to York Water on each day including the date of its acceptance of the shares of York Water Common Stock through and including the date of disposition of such shares that (1) either (a) no portion of the assets used by such purchaser or transferee to acquire shares of York Water Common Stock constitutes assets of any Plan or (b) the acquisition, holding and disposition of shares of York Water Common Stock by such purchaser or transferee will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation under any applicable Similar Laws and (2) it will notify York Water and the trustee immediately if, at any time, it is no longer able to make the representations contained in (1) above. Any purported transfer of the securities to a transferee that does not comply with the foregoing requirements shall be null and void ab initio.

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.

After the public offering of the shares of York Water Common Stock described herein, the public offering price and the concessions may be changed by the underwriter.

The following table shows the per share and total underwriting discount to be paid to the underwriter by us. These amounts are shown assuming both no exercise and full exercise of the underwriter’s option:

We estimate that the total expenses of this offering, excluding underwriting discounts and commissions, will be approximately $    , which will be paid by us.

We have agreed that we will not (i) issue, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of York Water Common Stock or any securities convertible into or exercisable or exchangeable for, or that represent the right to receive, York Water Common Stock, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of York Water Common Stock (iii) file any registration statement with the SEC relating to the offering of any shares of York Water Common Stock or any securities convertible into or exercisable or exchangeable for York Water Common Stock, (iv) offer to sell shares of York Water Common Stock pursuant to a dividend reinvestment plan or direct share purchase plan at a discount to fair market value or (v) publicly announce an intention to effect any transaction or action specified in (i), (ii), (iii) or (iv), in each case without the prior written consent of Janney Montgomery Scott LLC for a period of 60 days after the date of this prospectus supplement, subject to certain limited exceptions set forth in the underwriting agreement.

York Water Common Stock is listed on the NASDAQ Global Select Market under the symbol “YORW.”

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.

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.

In this prospectus, unless the context specifically indicates otherwise “the Company,” “we,” “us” and “our” refer to 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. The information contained on our website is not incorporated by reference into, and does not form any part of, this prospectus.

We discuss in this prospectus and in documents that we have incorporated into this prospectus by reference certain matters which are not historical facts, but which are “forward-looking statements.” Words such as “may,” “should,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan” and similar expressions are intended to identify “forward-looking statements.” We intend these forward-looking statements to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to statements regarding:

These forward-looking statements reflect what the Company currently anticipates will happen. What actually happens could differ materially from what it currently anticipates will happen. The Company does not intend to make a public announcement when forward-looking statements in this report are no longer accurate, whether as a result of new information, what actually happens in the future or for any other reason. Important matters that may affect what will actually happen include, but are not limited to:

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

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.

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.

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.

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 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.

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.

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.

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.

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.

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 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.

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.

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 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.

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 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.

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.

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.

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.

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.

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 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.

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.

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 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.

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 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, 2022 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.

We will receive all of the net proceeds from the sale by us of the securities registered under the registration statement of which this prospectus is a part. Unless otherwise specified in a prospectus supplement accompanying this prospectus, we expect to use the net proceeds from the sale of our securities for general corporate purposes, which may include, among other things, reduction or refinancing of debt or other corporate obligations, potential acquisitions of complementary businesses, the financing of capital expenditures and other general corporate purposes, including working capital.

The actual application of proceeds from the sale of securities issued hereunder will be described in the applicable prospectus supplement relating thereto. The precise amount and timing of the application of such proceeds will depend upon our funding requirements and the availability and cost of other funds. We currently have no plans for specific use of the net proceeds. We will specify the principal purposes for which the net proceeds from the sale of our securities will be used in a prospectus supplement at the time of sale.

The following description of our capital stock is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to our Amended and Restated Articles of Incorporation, which is an exhibit to our Current Report on Form 8-K filed with the SEC on May 4, 2010, and our Amended and Restated By-laws, which is an exhibit to our Current Report on Form 8-K filed with the SEC on January 26, 2012, each of which is incorporated by reference herein. We encourage you to read our articles, our by-laws and the applicable provisions of the Pennsylvania Business Corporation Law of 1988, as amended, for additional information.

Our authorized capital stock consists of 47,000,000 shares, of which 46,500,000 shares are common stock and 500,000 shares are preferred stock, each without par value.

Each share of common stock entitles the holder to one vote on each matter presented at a meeting of shareholders or to express consent or dissent to corporate action in writing without a meeting. Cumulative voting in an election of directors is not permitted under our articles of incorporation. Pursuant to our by-laws, our Board of Directors consists of at least eight and not more than twelve directors, with three separate classes of directors and with each such class elected every three years to a staggered three-year term of office. As a result of this classification, a greater number of votes are required to elect a director than if the entire Board of Directors were elected at the same time, thus making it more difficult for shareholders to obtain board representation in proportion to their shareholdings.

All shares of common stock are entitled to participate pro rata in any dividends declared by our Board of Directors out of funds legally available therefor. Subject to the prior rights of creditors and of any shares of preferred stock which may be outstanding, all shares of common stock are entitled in the event of liquidation to participate ratably in the distribution of all our remaining assets.

Certain of our trust indentures and agreements relating to our outstanding indebtedness impose restrictions on the payment of dividends. In general, these restrictive provisions prohibit the payment of dividends on our common stock when cumulative dividend payments, over a specified period of time, exceed cumulative net income, over the same period, plus, in certain cases, a specified base amount. In view of our historic net income, management believes that these contractual provisions should not have any direct, adverse impact on the dividends we pay on our common stock. Notwithstanding these contractual provisions, our Board of Directors periodically considers a variety of factors in evaluating our common stock dividend rate. The continued maintenance of the current common stock dividend rate will be dependent upon (i) our success in financing future capital expenditures through debt and equity issuances, (ii) our success in obtaining future rate increases from the Pennsylvania Public Utility Commission (the “PPUC”), (iii) future interest rates, and (iv) other events or circumstances which could have an effect on operating results.

We also have 500,000 shares of preferred stock authorized, which our Board of Directors has discretion to issue in such series and with such preferences and rights as it may designate. Such preferences and rights may be superior to those of the holders of common stock. For example, the holders of preferred stock may be given a preference in payment upon our liquidation, or for the payment or accumulation of dividends before any distributions are made to the holders of common stock. No shares of the preferred stock have been issued.

We are subject to various anti-takeover provisions of the Pennsylvania Business Corporation Law of 1988, as amended (the “PBCL”) Generally, these provisions are triggered if any person or group acquires, or discloses

intent to acquire, 20% or more of a corporation’s voting power, unless the acquisition is under a registered firm commitment underwriting or, in certain cases, approved by the board of directors. These provisions:

In addition, as permitted by Pennsylvania law, an amendment to our articles of incorporation or other corporate action that is approved by shareholders may provide mandatory special treatment for specified groups of nonconsenting shareholders of the same class. For example, an amendment to our articles of incorporation or other corporate action may provide that shares of common stock held by designated shareholders of record must be cashed out at a price determined by the corporation, subject to applicable dissenters’ rights.

The issuance of shares of preferred stock, while potentially providing desirable flexibility in connection with raising capital for our needs and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock.

Certain provisions of by-laws may have the effect of discouraging unilateral tender offers or other attempts to take over and acquire our business. These provisions might discourage some potentially interested purchaser from attempting a unilateral takeover bid for us on terms, which some shareholders might favor.

Our by-laws require our Board of Directors to be divided into three classes that serve staggered three-year terms. When a board is staggered, hostile bidders must win more than one proxy fight at successive shareholder meetings in order to exercise control of the board of the target.

The by-laws also require that any shareholder intending to nominate a candidate for election as a director must give written notice of the nomination, containing certain specified information, to our secretary not later than 90 days nor earlier than 120 days in advance of the meeting at which the election is to be held.

The Pennsylvania Public Utility Commission, or PPUC, has jurisdiction over a change in control of us or the acquisition of us by a third party. The PPUC approval process can be lengthy and may deter a potentially interested purchaser from attempting to acquire a controlling interest in us.

There are no preemptive rights, sinking fund provisions, conversion rights or redemption provisions applicable to the common stock. Holders of fully paid shares of common stock are not subject to any liability for further calls or assessments.

The Transfer Agent and Registrar for the common stock is Broadridge Corporate Issuer Solutions, Inc, PO Box 1342, Brentwood, NY 11717.

The following is a summary of the general terms and provisions of the debt securities we may offer under this prospectus and one or more prospectus supplements. When we offer to sell a particular series of debt securities, we will describe the specific terms of the series in a prospectus supplement. The following description of debt securities will apply to the debt securities offered by this prospectus unless we provide otherwise in the applicable prospectus supplement. The applicable prospectus supplement for a particular series of debt securities may specify different or additional terms.

We may issue senior, senior subordinated, or subordinated debt securities, and in any case may be secured or unsecured. The debt securities will be our direct obligations. Senior securities will rank equally and ratably in right of payment with other indebtedness of ours that is not subordinated. Senior subordinated securities will be subordinated in right of payment to the prior payment in full of senior indebtedness, as defined in the applicable prospectus supplement, and may rank equally and ratably with any other senior subordinated indebtedness. Subordinated securities will be subordinated in right of payment to senior subordinated securities.

Debt securities may be issued in one or more series with the same or various maturities, at par, at a premium, or at a discount. We need not issue all debt securities of one series at the same time. Unless we provide otherwise, we may reopen a series, without the consent of the holders of such series, for issuances of additional securities of that series. We may issue debt securities with terms different from those of debt securities that we previously issued.

The form of indenture has been filed as an exhibit to the registration statement of which this prospectus is a part and is subject to any amendments or supplements that we may enter into with the trustee(s), however, we may issue debt securities not subject to the indenture provided such terms of debt securities are not otherwise required to be set forth in the indenture. Each indenture will be subject to and governed by the Trust Indenture Act of 1939, as amended, and we may supplement the indenture from time to time. The material terms of the indenture are summarized below and we refer you to the indenture for a detailed description of these material terms. Additional or different provisions that are applicable to a particular series of debt securities will, if material, be described in a prospectus supplement relating to the offering of debt securities of that series. These provisions may include, among other things and to the extent applicable, the following:

Unless otherwise indicated in the applicable prospectus supplement, we will issue debt securities in fully registered form without coupons and in denominations of $1,000 and in integral multiples of $1,000, and interest will be computed on the basis of a 360-day year of twelve 30-day months. If any interest payment date or the maturity date falls on a day that is not a business day, then the payment will be made on the next business day without additional interest and with the same effect as if it were made on the originally scheduled date. “Business day” means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York, and on which the trustee and commercial banks are open for business in New York, New York.

Unless we inform you otherwise in a prospectus supplement, each series of our senior debt securities will rank equally in right of payment with all of our other unsubordinated debt. The subordinated debt securities will rank junior in right of payment and be subordinate to all of our unsubordinated debt.

Unless otherwise indicated in the applicable prospectus supplement, the trustee will act as paying agent and registrar for the debt securities under the indenture. We may act as paying agent under the indenture.

The prospectus supplement will contain a description of United States federal income tax consequences relating to the debt securities, to the extent applicable.

The applicable prospectus supplement will describe any covenants, such as restrictive covenants restricting us or our subsidiaries, if any, from incurring, issuing, assuming or guarantying any indebtedness or restricting us or our subsidiaries, if any, from paying dividends or acquiring any of our or its capital stock.

The indenture permits a consolidation or merger between us and another entity and/or the sale, conveyance or lease by us of all or substantially all of our property and assets, provided that:

If we consolidate or merge with or into any other entity, or sell or lease all or substantially all of our assets in compliance with the terms and conditions of the indenture, the resulting or acquiring entity will be substituted for us in the indenture and the debt securities with the same effect as if it had been an original party to the indenture and the debt securities. As a result, such successor entity may exercise our rights and powers under the indenture and the debt securities, in our name and, except in the case of a lease, we will be released from all our liabilities and obligations under the indenture and under the debt securities.

Notwithstanding the foregoing, we may transfer all of our property and assets to another entity if, immediately after giving effect to the transfer, such entity is our wholly owned subsidiary. The term “wholly

owned subsidiary” means any subsidiary in which we and/or our other wholly owned subsidiaries, if any, own all of the outstanding capital stock.

Under the indenture, some of our rights and obligations and some of the rights of the holders of the debt securities may be modified or amended with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities affected by the modification or amendment. However, the following modifications and amendments will not be effective against any holder without its consent:

Under the indenture, the holders of not less than a majority in aggregate principal amount of the outstanding debt securities may, on behalf of all holders of the debt securities:

Unless we indicate otherwise in the applicable prospectus supplement, “event of default” under the indenture will mean, with respect to any series of debt securities, any of the following:

If an event of default occurs and continues, the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of such series may declare the entire principal of all the debt securities to be due and payable immediately, except that, if the event of default is caused by certain events in bankruptcy, insolvency or reorganization, the entire principal of all of the debt securities of such series will become due and payable immediately without any act on the part of the trustee or holders of the debt securities. If such a declaration occurs, the holders of a majority of the aggregate principal amount of the outstanding debt securities of such series can, subject to conditions, rescind the declaration.

The indenture requires us to furnish to the trustee not less often than annually, a certificate from our principal executive officer, principal financial officer or principal accounting officer, as the case may be, as to such officer’s knowledge of our compliance with all conditions and covenants under the indenture. The trustee may withhold notice to the holders of debt securities of any default, except defaults in the payment of principal

of or interest on any debt securities if the trustee in good faith determines that the withholding of notice is in the best interests of the holders. For purposes of this paragraph, “default” means any event which is, or after notice or lapse of time or both would become, an event of default under the indenture.

The trustee is not obligated to exercise any of its rights or powers under the indenture at the request, order or direction of any holders of debt securities, unless the holders offer the trustee satisfactory security or indemnity. If satisfactory security or indemnity is provided, then, subject to other rights of the trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities may direct the time, method and place of:

The holder of a debt security will have the right to begin any proceeding with respect to the indenture or for any remedy only if:

However, the holder of any debt security will have an absolute right to receive payment of principal of and interest on the debt security when due and to institute suit to enforce this payment.

Satisfaction and Discharge of Indenture. Unless otherwise indicated in the applicable prospectus supplement, if at any time,

then the indenture shall cease to be of further effect with respect to the debt securities of such series, except for:

Defeasance and Covenant Defeasance. Unless otherwise indicated in the applicable prospectus supplement, we may elect with respect to any debt securities of any series either:

We must comply with the following conditions before the defeasance or covenant defeasance can be effected:

In connection with defeasance, any irrevocable trust agreement contemplated by the indenture must include, among other things, provision for:

The accompanying prospectus supplement may further describe any provisions permitting or restricting defeasance or covenant defeasance with respect to the debt securities of a particular series.

Unless otherwise indicated in the applicable prospectus supplement, each debt security offered by this prospectus will be issued in the form of one or more global debt securities representing all or part of that series of debt securities. This means that we will not issue certificates for that series of debt securities to the holders. Instead, a global debt security representing that series will be deposited with, or on behalf of, a securities depositary and registered in the name of the depositary or a nominee of the depositary. Any such depositary must be a clearing agency registered under the Securities Exchange Act of 1934. We will describe the specific terms of the depositary arrangement with respect to a series of debt securities to be represented by a global security in the applicable prospectus supplement.

We will give notices to holders of the debt securities by mail at the addresses listed in the security register. In the case of notice in respect of unregistered securities or coupon securities, we may give notice by publication in a newspaper of general circulation in New York, New York.

The particular terms of a series of debt securities will be described in a prospectus supplement relating to such series of debt securities. Any indentures will be subject to and governed by the Trust Indenture Act of 1939, as amended, and may be supplemented or amended from time to time following their execution. Unless otherwise stated in the applicable prospectus supplement, we will not be limited in the amount of debt securities that we may issue, and neither the senior debt securities nor the subordinated debt securities will be secured by any of our property or assets. Thus, by owning debt securities, you are one of our unsecured creditors.

From time to time, we may maintain deposit accounts and conduct other banking transactions with the trustee to be appointed under the indenture or its affiliates in the ordinary course of business.

We may sell our securities from time to time to or through underwriters, dealers or agents or directly to purchasers, in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. We may also issue these securities as compensation to such agents, underwriters or dealers for making sales of our securities. We may use these methods in any combination.

We may use an underwriter or underwriters in the offer or sale of our securities.

We may use a dealer to sell our securities.

We may designate agents to solicit offers to purchase our securities.

We may authorize our agents and underwriters to solicit offers by certain institutions to purchase our securities at the public offering price under delayed delivery contracts.

We may directly solicit offers to purchase our securities, and we may directly sell our securities to institutional or other investors, including our affiliates. We will describe the terms of our direct sales in the prospectus supplement. We may also sell our securities upon the exercise of rights which we may issue.

Direct sales to our shareholders may be accomplished through shareholder subscription rights distributed to shareholders. In connection with the distribution of shareholder subscription rights to shareholders, if all of the underlying securities are not subscribed for, we may sell any unsubscribed securities to third parties directly or through underwriters or agents. In addition, whether or not all of the underlying securities are subscribed for, we may concurrently offer additional securities to third parties directly or through underwriters or agents. The shareholder subscription rights will be distributed as a dividend to the shareholders for which they will pay no separate consideration and will not be transferable. The prospectus supplement with respect to the offer of securities under shareholder subscription rights will set forth the relevant terms of the shareholder subscription rights, including:

Underwriters, dealers and agents that participate in the distribution of our securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive and any profit they make on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. Any underwriters or agents will be identified and their compensation described in a prospectus supplement. We may indemnify agents, underwriters, and dealers against certain civil liabilities, including liabilities under the Securities Act, or make contributions to payments they may be required to make relating to those liabilities. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

Representatives of the underwriters or agents through whom our securities are or may be sold for public offering and sale may engage in over-allotment, stabilizing transactions, syndicate short covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934. Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position. Stabilizing transactions permit bids to purchase the offered securities so long as the stabilizing bids do not exceed a specified maximum.

Syndicate covering transactions involve purchases of the offered securities in the open market after the distribution has been completed in order to cover syndicate short positions. Penalty bids permit the representative of the underwriters or agents to reclaim a selling concession from a syndicate member when the offered securities originally sold by such syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Such stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the offered securities to be higher than it would otherwise be in the absence of such transactions. These transactions may be effected on a national securities exchange and, if commenced, may be discontinued at any time. Underwriters, dealers and agents may be customers of, engage in transactions with or perform services for, us and our subsidiaries in the ordinary course of business.

In compliance with guidelines of the Financial Institution Regulatory Authority, or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.

Certain legal matters with respect to the validity of the securities being offered hereby will be passed on for us by Reed Smith LLP, Pittsburgh, Pennsylvania. Any underwriters will be advised about other issues relating to any offering by their own legal counsel.
