YORK WATER CO (YORW) Business

Item 1. Business.

The York Water Company (the “Company”) is the oldest investor-owned water utility in the United States and is duly organized under the laws of the
Commonwealth of Pennsylvania.  The Company has operated continuously since 1816.  The primary business of the Company is to impound, purify to meet or exceed safe drinking water standards and distribute water.  The Company also owns and operates
three wastewater collection systems and twelve wastewater collection and treatment systems.  The Company operates within its franchised water and wastewater territory, which covers portions of 58 municipalities within four counties in south-central
Pennsylvania.  The Company is 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.  The Company must obtain PPUC approval before changing any practices associated with the aforementioned areas.

Water service is supplied through the Company’s own distribution system.  The Company obtains the bulk of its water supply for its primary system for
York and Adams Counties from both the South Branch and East Branch of the Codorus Creek, which together have an average daily flow of approximately 73.0 million gallons from a combined watershed area of approximately 117 square miles.  The Company
has two reservoirs on this primary system, Lake Williams and Lake Redman, which together hold up to approximately 2.5 billion gallons of water.  The Company supplements these 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.  The Company obtains its water supply for its system for Franklin County from the Roxbury Dam on the Conodoguinet Creek, which has an average
daily flow of approximately 26.0 million gallons from a watershed area of approximately 33 square miles.  The Company has a reservoir on this system which holds up to approximately 330 million gallons of water.  The Company also owns fifteen wells
which are capable of providing a safe yield of approximately 923,000 gallons per day to supply water to the customers of its groundwater satellite systems in York, Adams, and Lancaster Counties.  As of December 31, 2025, the Company’s average daily
availability was 41.1 million gallons, and average daily consumption was approximately 23.7 million gallons.  The Company’s service territory had an estimated population of 214,000 as of December 31, 2025.  Industry within the Company’s 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.

The Company's water business is somewhat dependent on weather conditions, particularly the amount and timing of precipitation.  Revenues are particularly
vulnerable to weather conditions in the summer months.  Prolonged periods of hot and dry weather generally cause increased water usage for watering lawns, washing cars, and keeping golf courses and sports fields irrigated.  Conversely, prolonged
periods of dry weather could lead to drought restrictions from governmental authorities.  Despite the Company’s adequate water supply, customers may be required to cut back water usage under such drought restrictions which would negatively impact
revenues.  The Company has addressed some of this vulnerability by instituting minimum customer charges which are intended to cover fixed costs of operations under all likely weather conditions.

The Company’s business does not require large amounts of working capital and is not dependent on any single customer or a very few customers for a
material portion of its business.  Increases in revenues are generally dependent on the Company’s ability to obtain rate increases from the PPUC in a timely manner and in adequate amounts and to increase volumes of water sold through increased
consumption and increases in the number of customers served.  The Company continuously looks for water and wastewater acquisition and expansion opportunities both within and outside its current service territory as well as additional opportunities
to enter into bulk water contracts with municipalities and other entities to supply water.

The Company has agreements with several municipalities to provide billing and collection services.  The Company continues to review and consider
opportunities to expand this initiative to further diversify the business.

Competition

As a regulated utility, the Company operates within an exclusive franchised territory that is substantially free from direct competition with other
public utilities, municipalities, and other entities.  Although the Company has been granted an exclusive franchise for each of its existing community water and wastewater systems, the ability of the Company to expand or acquire new service
territories may be affected by currently unknown competitors obtaining franchises to surrounding systems by application or acquisition.  These competitors may include other investor-owned utilities, nearby municipally-owned utilities and sometimes
competition from strategic or financial purchasers seeking to enter or expand in the water and wastewater industry.  The addition of new service territory and the acquisition of other utilities are generally subject to review and approval by the
PPUC.

Water and Wastewater Quality and Environmental Regulations

Provisions of water and wastewater service are subject to regulation under the federal Safe Drinking Water Act, the Clean Water Act and related state
laws, and under federal and state regulations issued under these laws.  In addition, the Company is subject to federal and state laws and other regulations relating to solid waste disposal, dam safety and other aspects of its operations.

The federal Safe Drinking Water Act establishes criteria and procedures for the U.S. Environmental Protection Agency, or EPA, to develop national quality
standards.  Regulations issued under this Act, and its amendments, set standards on the amount of certain contaminants allowable in drinking water.  Current requirements are not expected to have a material impact on the Company’s operations or
financial condition as it already meets or exceeds standards.  In the future, the Company may be required to change its method of treating drinking water and may incur additional capital investments if new regulations become effective.

Under the requirements of the Pennsylvania Safe Drinking Water Act, or SDWA, the Pennsylvania Department of Environmental Protection, or DEP, regulates
the quality of the finished water supplied to customers.  The DEP requires the Company to submit monthly reports showing the results of daily bacteriological and other chemical and physical analyses. As part of this requirement, the Company
conducts over 70,000 laboratory tests annually.  Management believes that the Company complies with the standards established by the agency under the SDWA.  The DEP assists the Company by regulating discharges into the Company’s watershed area to
prevent and eliminate pollution.

The federal Groundwater Rule establishes protections against microbial pathogens in community water supplies.  This rule requires additional testing of
water from well sources, and under certain circumstances requires demonstration and maintenance of effective disinfection.  The Company holds public water supply permits issued by the DEP, which establishes the groundwater source operating
conditions for its wells, including demonstrated 4-log treatment of viruses.  All of the groundwater satellite systems operated by the Company are in compliance with the federal Groundwater Rule.

The Clean Water Act regulates discharges from water and wastewater treatment facilities into lakes, rivers, streams, and groundwater.  The Company
complies with this Act by obtaining and maintaining all required permits and approvals for discharges from its water and wastewater facilities and by satisfying all conditions and regulatory requirements associated with the permits.

The DEP monitors the quality of wastewater discharge effluent under the provisions of the National Pollutant Discharge Elimination System, or NPDES.  The
Company submits monthly reports to the DEP showing the results of its daily effluent monitoring and removal of sludge and biosolids.  The Company is not aware of any significant environmental remediation costs necessary from the handling and
disposal of waste material from its wastewater operations.

The primary avenue for lead and copper to enter drinking water is through plumbing materials.  The Company is required to comply with the Lead and Copper
Rule established by the EPA and administered by the DEP.  The Company must monitor drinking water at customer taps for compliance with this rule.  If lead concentrations exceed an action level, the Company must undertake additional actions to
control corrosion, inform the public about steps they should take to protect their health and may be required to replace lead service lines under its control.  The Company is currently in compliance with standards under the Lead and Copper Rule.

The EPA published the Lead and Copper Rule Revisions, or LCRR, that included a requirement to submit a service line inventory and a lead service line
replacement plan to the respective states or agencies by October 16, 2024.  Additionally, the EPA adopted a new regulation, the Lead and Copper Rule Improvements, or LCRI, to focus on the replacement of lead and certain galvanized steel service
lines and ensure public education is provided along with sampling at elementary schools and childcare facilities by 2037.  The Company successfully submitted its service line inventory and is developing elementary school and childcare facility
mailings in preparation for LCRI sampling compliance.

The DEP and the Susquehanna River Basin Commission, or SRBC, regulate the amount of water withdrawn from streams in the watershed to assure that
sufficient quantities are available to meet the needs of the Company and other regulated users.  Through its Division of Dam Safety, the DEP regulates the operation and maintenance of the Company’s impounding dams.  The Company routinely inspects
its dams and prepares annual reports of their condition as required by DEP regulations.  The DEP reviews these reports and inspects the Company’s dams.

Since 1980, the DEP has required any new dam to have a spillway that is capable of passing the design flood without overtopping the dam.  The design
flood is either the Probable Maximum Flood, or PMF, or some fraction of it, depending on the size and location of the dam.  PMF is very conservative and is calculated using the most severe combination of meteorological and hydrologic conditions
reasonably possible in the watershed area of a dam.

The Company engaged a professional engineer to analyze the spillway capacities at the Lake Williams and Lake Redman dams and validate the DEP’s
recommended flood design for the dams.  Management presented the results of the study to the DEP in December 2004, and DEP then requested that the Company submit a proposed schedule for the actions to address the spillway capacities.  Thereafter,
the Company retained an engineering firm to prepare preliminary designs for increasing the spillway capacities to pass the PMF through armoring the dams with roller compacted concrete.  Management met with the DEP on a regular basis to review the
preliminary design and discuss scheduling, permitting, and construction requirements including their concern regarding the stability of the Lake Williams spillway in light of current design standards.  The Company completed the final design and the
permitting process to armor the dam and replace the spillway of the Lake Williams dam and began construction in 2022.  The Company completed the dam armoring and spillway replacement in 2023 at a total cost of approximately $40 million.  Additional
capital expenditures were incurred in 2024 and 2025 and are expected to be completed in 2026 for sitework around the dam and reservoir.  The Lake Redman dam will be reassessed following the completion of the work on the Lake Williams dam.

Capital expenditures and operating costs required as a result of water quality standards and environmental requirements have been traditionally
recognized by state public utility commissions as appropriate for inclusion in establishing rates.  The capital expenditures currently required as a result of water quality standards and environmental requirements have been budgeted in the
Company’s capital program and represent less than 15% of its expected total capital expenditures over the next five years.  The Company is currently in compliance with wastewater environmental standards and does not anticipate any major capital
expenditures for its current wastewater business.

Growth

(All dollar amounts are stated in thousands of dollars)

The Company continues to grow its number of customers and distribution facilities.

The growth in the number of customers is due primarily to the acquisition of water and wastewater systems and organic growth. During the year ended
December 31, 2025, the Company increased its number of customers from 79,771 to 81,292.  See “Management’s Discussion and Analysis – Acquisitions and Growth” for a discussion of the Company’s recent acquisitions.

The Company continues to grow its water distribution and wastewater collection systems to provide reliable service to its expanding franchised service
territory and the increasing population within that territory.  During the year ended December 31, 2025, the Company installed additional water distribution mains resulting in 1,105 miles of water mains as of December 31, 2025.

The Company’s growth in revenues is primarily a result of customer growth and increases in water and wastewater rates.  During the year ended December
31, 2025, the Company recognized revenue of $77,488, an increase of $2,529, or 3.4%, as compared to $74,959 during the year ended December 31, 2024.  In 2025, operating revenue was derived from the following sources and in the following
percentages: residential, 64%; commercial and industrial, 29%; and other, 7%, which is primarily from the provision for fire service but includes other water and wastewater service-related income.  See “Management’s Discussion and Analysis – Rate
Matters” for a discussion of the Company’s rate case management.
