ITEM 1A. RISK FACTORS.

The risks described below are not the only risks facing Zurn Elkay. Additional risks and uncertainties not currently known to us, or those risks we currently view to be immaterial, may also materially and adversely affect our business, financial condition or results of operations. In addition, see Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 for further discussion of some of the factors that could affect future results. If any of these risks materialize, our business, financial condition, results of operations or cash flows could be materially and adversely affected.

Strategic Risks

Economic and financial market weakness, as well as overall challenging market cycles, may particularly impact the markets we serve, and, as a result may adversely affect our financial condition or results of operations.

Our business operations may be adversely affected by volatility and weaknesses in the overall economy and financial markets. Weak, challenging or volatile economic conditions in the end markets, businesses or geographic areas in which we sell our products typically reduces demand for our products and results in a decrease in sales volume.

Our financial performance depends, in large part, on conditions in the markets that we serve in the U.S. and, to a lesser extent, the global economy generally. Some of the end markets we serve are highly cyclical, and some at times have experienced greater cyclicality than others. Any sustained weakness in demand or downturn or uncertainty in the economy, could materially reduce our net sales and profitability.

For example, sales to the construction industry are driven by trends in institutional, commercial, and residential construction, housing starts and trends in residential repair and remodeling. Consumer confidence, employment rates, weather conditions, interest rates, credit standards and availability of consumer credit and income levels play a significant role in driving demand in institutional, commercial and residential construction, repair and remodeling sectors. A drop or weakness in consumer confidence, prolonged adverse weather conditions, lack of availability or increased cost of credit, tightened credit standards or increased unemployment could materially impact demand for sales of our products and/or result in downward pressure on product pricing and our profit margins, any or all of which could adversely affect our financial results.

Volatility and disruption of financial markets could limit the ability of our customers to obtain adequate financing to maintain operations and may cause them to terminate existing purchase orders, reduce the volume of products they purchase from us in the future or impact their ability to pay their receivables. Adverse economic and financial market conditions may also cause our suppliers to be unable to meet their commitments to us or may cause suppliers to make changes in the credit terms they extend to us, such as shortening the required payment period for outstanding accounts receivable or reducing or eliminating the amount of trade credit available to us.

The markets we serve are highly competitive; an inability to effectively compete would adversely affect our business, financial condition and results of operations.

We operate in highly competitive markets. Some of our competitors have achieved substantially more market penetration in certain of the markets in which we operate. Some of our competitors are larger and may have greater financial and other resources than we do, and our competitors may adopt more aggressive sales policies and devote greater resources to the development, promotion and sale of their products than we do, all of which could result in a loss of customers and adversely affect our results of operations.

We compete against both large international and national rivals, as well as many regional competitors. Increased competition in any of the markets in which we operate could result in substantial downward pressure on product pricing and our profit margins, thereby adversely affecting our financial results. We cannot provide assurance that we will be able to maintain or increase the current market share of our products successfully in the future.

If we are unable to effectively manage risks associated with changing technology, including artificial intelligence, product innovation and new product development, manufacturing techniques, distribution channels and business continuity, we may be at a competitive disadvantage.

The successful implementation of our business strategy requires us to continuously evolve our existing products and introduce new products to meet customers' needs in the industries we serve. Our products are characterized by stringent performance and specification requirements that mandate a high degree of manufacturing and engineering expertise. If we fail to meet these requirements, our business and ability to compete effectively could suffer. We believe our customers rigorously evaluate their suppliers on numerous factors, including product quality, price competitiveness, technical and manufacturing expertise, development and product design capability, new product innovation, reliability and timeliness of delivery, operational flexibility, customer service and overall management. Our ongoing success depends on our ability to continue to meet our customers' changing specifications with respect to these criteria.

We cannot ensure that we will be able to introduce new products that may be necessary to remain competitive within our businesses or to effectively adopt technological advances, including use of artificial intelligence, related to our products or operational processes. If our competitors successfully leverage artificial intelligence, including generative artificial intelligence and machine learning to enhance efficiency, improve customer experience, or accelerate innovation more quickly or more successfully than us, this could affect our competitive position, profitability and results of operations. Further, such new products and technologies may create additional exposure or risk. In addition, there is potential for the misuse of artificial intelligence and machine-learning technology by our personnel while carrying out their responsibilities. The deployment of generative artificial intelligence tools also creates opportunities for the misuse or loss of data, the inadvertent dissemination of our confidential or proprietary information or the inadvertent use of third parties' intellectual property. We cannot ensure that we can adequately protect our own technological developments to produce a sustainable competitive advantage.

Furthermore, we may be subject to business continuity risk in the event of an unexpected loss at a material facility or operation. We cannot ensure adequate insurance protection against such a loss.

We may be unable to realize intended benefits from our ongoing Supply Chain Optimization and Footprint Repositioning initiatives, restructuring and divestiture efforts, and as a result our profitability or our business otherwise might be adversely affected.

To operate more efficiently, control costs and refine our business focus, we periodically undertake restructuring plans, which can include facility consolidations, product rationalizations, workforce reductions, manufacturing and supply chain repositioning and other cost reduction initiatives. We also periodically choose to divest operations or product lines that we no longer believe are additive or complementary to our business or strategic direction. These plans are intended to reduce operating costs, to modify our footprint to reflect changes in the markets we serve, to reflect changes in business focus, to strengthen focus on our core business and/or to address overall manufacturing overcapacity, including as a result of acquisitions. If we do not successfully manage our current restructuring activities, or any other restructuring activities or divestitures that we may undertake in the future, expected efficiencies, benefits and cost savings might be delayed or not realized, and our operations and business could be disrupted.

In addition, as a result of such actions, we expect to incur restructuring expenses and other charges (including, for example, potential impairment charges related to fixed assets, goodwill and other intangibles), which may be material, and may exceed our estimates. Several factors could cause restructuring or divestiture activities to adversely affect our business, financial condition and results of operations. These include potential disruption of our operations, customer relationships and other aspects of our business. Employee morale and productivity could also suffer and may result in unwanted employee attrition. These activities require substantial management time and attention and may divert management from other important work or result in a failure to meet operational targets. Divestitures may also result in obligations to buyers or other parties that could have a financial effect after the transaction is completed. Moreover, we could make changes to, or experience delays in executing, any restructuring or divestiture plans, any of which could cause further disruption and additional unanticipated expense.

An inability to effectively integrate acquisitions, mergers or other business combinations could adversely affect our business, financial condition, results of operations or cash flows. Additionally, dispositions or liabilities retained in connection with dispositions could negatively affect us.

Acquisitions, mergers and other business combinations are part of our growth strategy, and we have completed several in recent years. We also sell or divest businesses, products and technologies from time to time. We cannot ensure that we will be able to complete any future acquisition or divestiture, successfully integrate any acquired business or operations, or accomplish our strategic objectives as a result of any such acquisition or divestiture.

Acquisitions are often undertaken to improve the operating results of either or both of the acquirer and the acquired company and we cannot ensure that we will be successful in this regard. We cannot provide any assurance that we will be able to fully realize the intended benefits from our acquisitions. Acquisitions involve risks, including the possible inability to integrate an acquired business into our operations, potential failure to realize anticipated benefits, diversion of management's attention, issues in customer transitions, potential inadequacies of indemnities and other contractual remedies and unanticipated problems, risks or liabilities, including environmental, some or all of which could have a material adverse effect on our business, financial condition, results of operations or cash flows.

If dispositions are not completed in a timely manner, there may be a negative effect on our cash flows and/or our ability to execute our strategy. In addition, we may not realize some or all of the anticipated benefits of our dispositions.

From time to time, we have sold or divested businesses, products and technologies. With respect to some of these former businesses, we may contractually agree to indemnify the counterparties against, or otherwise retain, certain liabilities, including, certain lawsuits, tax liabilities, product liability claims, and environmental matters. Even without ongoing contractual indemnification obligations, we could be exposed to liabilities arising out of the businesses for certain activities prior to the

divestitures. In addition, certain of the counterparties to those divestitures and/or the divested businesses have agreed to indemnify us or assume certain liabilities relating to those divestitures. However, there can be no assurance that the indemnity or assumption of liability by the counterparties or divested businesses will be sufficient to protect us against the full amount of these liabilities, or that a counterparty or divested business will be able to fully satisfy its obligations. Third parties also could seek to hold us responsible for any of the liabilities that a counterparty or divested business agreed to assume. Even if we ultimately succeed in recovering any amounts for which we were initially held liable, we may be temporarily required to bear these losses.

The loss or financial instability of any significant customer or customers accounting for our backlog could adversely affect our business, financial condition, results of operations or cash flows.

A substantial part of our business is concentrated with a few customers, and we have certain customers that are significant to our business. During the year ended December 31, 2025, our top five customers accounted for approximately 38% of our consolidated net sales, with one customer accounting for 18% of consolidated net sales. The loss of one or more of these customers or other major customers, or a deterioration in our relationship with any of them could have a material adverse effect on our business, financial condition, results of operations or cash flows.

Our contracted backlog is comprised of future orders for our products from a broad number of customers. Defaults by any of the customers that have placed significant orders with us, whether because of bankruptcy, illiquidity, operational problems or otherwise, could have a significant adverse effect on our net sales, profitability and cash flow. As of December 31, 2025, all of our backlog was scheduled to ship during the year ending December 31, 2026.

We rely on independent distributors and independent sales representatives. Termination of one or more of our relationships with any of our key independent distributors and / or a substantial number of independent representatives could have a material adverse effect on our business, financial condition, results of operations or cash flows.

We depend on approximately 1,000 independent sales representatives within North America, and approximately 65 third-party warehouses to distribute our products. In fiscal 2025, our three largest independent distributors generated approximately 32% of our consolidated net sales with the largest accounting for 18% of consolidated net sales.

The loss of one of our key distributors or of a substantial number of our other distributors or independent sales representatives, or an increase in the distributors' sales of competitors' products to our customers could have a material adverse effect on our business, financial condition, results of operations or cash flows.

The inability to adequately protect intellectual property, or defend against infringement claims brought against us, could adversely affect our business.

We attempt to protect our intellectual property through a combination of patent, trademark, copyright and trade secret protection, as well as third-party nondisclosure and assignment agreements. We cannot assure that any of our applications for protection of our intellectual property rights will be approved and successfully maintained or that our competitors will not infringe or successfully challenge our intellectual property rights. We also rely on unpatented proprietary technology and trade secrets.It is possible that others will independently develop the same or similar technology or otherwise obtain access to our unpatented technology. To protect our trade secrets and other proprietary information, we require employees, consultants and advisors to enter into confidentiality agreements. We cannot assure that these agreements will provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use, misappropriation or disclosure. If we are unable to maintain the proprietary nature of our technologies, our ability to sustain margins on some or all of our products may be affected, which could have a material adverse effect on our business.

In addition, in the ordinary course of our operations, we periodically seek to enforce our intellectual property rights through litigation or are subject to third party litigation claiming infringement, including in respect of some of our more profitable products. An adverse ruling or other unfavorable outcome in any such litigation could have a material adverse effect on our business, reputation, financial condition, results of operations or cash flows.

Operational Risks

Increases in the cost, and/or the availability, of raw materials, including as a result of tariffs or other trade protection measures, could adversely affect our business, financial condition, results of operations or cash flows.

Our manufacturing processes depend on third parties for raw materials, in particular bronze, iron, brass, stainless steel, carbon steel, zinc, and engineered plastics. While we strive to maintain alternative sources for most raw materials, our business is subject to the risk of price fluctuations, including as a result of, or in reaction to, tariffs, import duties, or other trade protection measures instituted by the U.S. or other countries, inefficiencies in the event of a need to change our suppliers, and delays in the delivery of and potential unavailability of our raw materials. In 2025, the U.S. government announced additional tariffs on goods imported from various countries into the U.S., and in response, certain of those countries countered with reciprocal tariffs and other actions. The U.S. government continues to negotiate with countries regarding tariffs and other trade actions. Also, trade wars or outbreaks of infectious diseases, could impact the cost or availability of goods or materials, both imported and domestic, or adversely affect demand for our products. Any such price fluctuations or delays, if material, could harm our profitability or operations. In addition, the loss of a substantial number of suppliers could result in material cost increases or reduce our production capacity. In addition to suppliers, we also rely on third party shippers to assist in transportation of our product throughout the supply chain. Reduced availability of transportation and the associated cost increases could adversely impact our profitability or operations.

We do not typically enter into hedge transactions to reduce our exposure to purchase price risks and cannot ensure that we would be successful in recouping any increases if these risks were to materialize. In addition, if we are unable to continue to purchase our required quantities of raw materials on commercially reasonable terms, or at all, or if we are unable to maintain or enter into new purchase contracts for our larger commodities, our business operations could be disrupted and our profitability could be adversely impacted.

The ongoing updates to our Enterprise Resource Planning ("ERP") systems, as well as failures of our data security and information technology infrastructure, cybersecurity breaches or misuse of artificial intelligence tools, could cause substantial business interruptions and adversely affect our business.

We continue to update our ERP systems across our Zurn Elkay operations. If these updates are ineffective, we could incur substantial business interruptions, including the inability to perform routine business transactions, which could have a material adverse effect on our financial performance. Further, these updates may not result in the benefits we intend or be timely implemented.

In addition, we depend heavily on information technology infrastructure to manage our business objectives and operations, support our customers’ requirements and protect sensitive information. In the regular course of our business, we also handle a range of sensitive security and customer information. We are subject to laws and rules issued by different agencies concerning safeguarding and maintaining the confidentiality of this information. There have been significant and increasing instances of data and security breaches, malicious interference with technology systems and industrial espionage involving companies in numerous industries, including cloud providers, and cybersecurity threats are becoming more complex. Like other companies, we have experienced, and will continue to experience, these types of threats; however, to date, we have not experienced a material threat or incident. In addition, at times a large percentage of our workforce may be working remotely, which may heighten these risks. While we have taken steps to maintain and enhance our cybersecurity by implementing additional security technologies, internal controls, network and data center resiliency, redundancy and disaster recovery processes and backup systems, upgrading our remote work environment and by obtaining insurance coverage, these measures may be inadequate and our technology systems could be vulnerable to disability, failures or unauthorized access. Furthermore, continued geopolitical turmoil has heightened the risk of cyberattacks. As discussed further below, the rapid evolution and increased adoption of artificial intelligence and machine learning technologies may intensify our cybersecurity risks. As a result, any inability by us to successfully manage our information systems, or respond effectively to any attack on or interference with our systems, including matters related to system and data security, privacy, reliability, compliance, performance and access, problems related to our systems caused by natural disasters, security breaches or malicious attacks, misuse of artificial intelligence tools, and any inability of these systems to fulfill their intended business purpose, could impede our ability to record or process orders, manufacture and ship in a timely manner, account for and collect receivables, protect sensitive data of the Company, our customers, our employees, our suppliers and other business partners, comply with our third party obligations of confidentiality and care, or otherwise carry on business in the normal course. Any such events could require costly remediation beyond levels covered by insurance and could cause us to lose customers and/or revenue, including as a result of legal or regulatory claims or proceedings, or damage our reputation, any of which could have a material adverse effect on our business and operating results.

We are also subject to an increasing number of evolving data privacy and security laws and regulations that impose requirements on us. We collect, store, access and otherwise process various types of confidential or sensitive data, including proprietary business information, personal data and other information that is subject to privacy and security laws, regulations

and/or customer-imposed controls. Failure to comply with such laws and regulations could result in the imposition of fines, penalties and other costs.

Our inability to attract and retain key personnel, as well as challenges with respect to the management of human capital resources, in a highly competitive industry may adversely affect our business.

Our ongoing success depends on our ability to recruit, retain and develop highly skilled management and key personnel, as well as our ability to effectively manage human capital resources. Competition for talented and skilled individuals in our industry is intense and we may not be able to successfully recruit, train or retain qualified personnel, or to effectively implement successions for existing personnel. If we fail to retain and recruit the necessary personnel or arrange for successors to key personnel, our business could materially suffer.

Increased frequency of weather events could disrupt construction activity and adversely affect the demand for our products.

Demand for our products is primarily driven by institutional and commercial construction activity, remodeling and retrofit opportunities, and to a lesser extent, new home starts. Weather is an important variable affecting financial performance as it significantly impacts construction activity. Adverse weather conditions, such as prolonged periods of cold or rain, blizzards, hurricanes and other severe weather patterns, the frequency of which might be affected by climate change, could delay or halt construction and remodeling activity, which could have a negative effect on our business. For example, an unusually severe or prolonged winter can lead to reduced or delayed construction activity which could magnify the seasonal decline in our net sales and earnings during the winter months and hamper the typical seasonal increase in net sales and earnings during the spring months.

The long-term effect of climate change could decrease demand for certain of our products.

Climate change may impact rainfall and water availability in many areas in unpredictable and different ways, which may change the way building owners and municipalities manage drinking, waste and storm water and may lead to new or modified regulations that may impact the market for our products. In certain areas, these changes could lead to a reduction in demand for certain of our products, although it also could increase demand for other of our products. The overall effect of this could be to reduce our sales and addressable market and/or alter our product sales mix in ways that reduce our margins, either of which could adversely impact our results of operations.

The physical impacts of climate change may materially adversely affect our business and financial condition.

The physical impacts of climate change on our operations are highly uncertain and could differ amongst the geographic regions of relevant markets and areas of operation. These may include changes in rainfall and storm patterns and intensities, water shortages, changing sea levels and changing temperatures. The impacts of climate change may materially and adversely affect the cost, production and financial performance of our operations. Further, any impacts to our business and financial condition as a result of climate change are likely to occur over an extended period of time and are therefore difficult to quantify with any degree of specificity. For example, extreme weather events may result in adverse physical effects on portions of our infrastructure, which could disrupt our supply chain and ultimately our business operations. In addition, disruption of transportation and distribution systems could result in reduced operational efficiency and customer service interruption. Climate-related events have the potential to disrupt our business, including the business of our suppliers, and may cause us to experience higher attrition, losses and additional costs to resume operations.

Our business and operations, and the operations of our suppliers, business partners and customers, may be adversely affected by future outbreaks of infectious diseases.

Future outbreaks of infectious diseases may result in widespread or localized health crises that adversely affect general commercial activity and the economies and financial markets of the countries and localities in which we operate, sell, and purchases goods and services. Any outbreak of infectious disease poses the risk that we or our employees, contractors, suppliers, customers, transportation providers, and other business partners may be prevented or impaired from conducting ordinary course business activities for an indefinite period of time, either at specific branches or on a broader scale, including due to shutdowns necessitated for the health and well-being of our employees, the employees of our business partners, or shutdowns that may be requested or mandated by governmental authorities. In addition, our suppliers, business partners and customers may also experience similar negative impacts from an outbreak of infectious disease. Global supply chains may be disrupted, causing shortages, which could impact our ability to manufacture or supply our products. Also, we could in the future experience increased compensation expenses associated with employee recruiting and employee retention to the extent employment opportunities multiply post-pandemic, causing the search for and retention of talent to become more competitive. This disruption of our employees, distributors, suppliers and customers may impact our sales and future operating results.

The unpredictable nature of new infectious diseases worldwide may continue to adversely impact our business, operations, suppliers and customers for the foreseeable future. Equally unpredictable are the responses of national and local governments and health authorities in affected regions to reduce community spread and protect employees, which may include

mandatory shutdowns or limitations on all or certain types of business operations. The ultimate impact of an infectious disease outbreak on our business depends on the severity, location and duration of outbreaks, and the actions of government and health officials in response to the outbreaks, none of which is predictable at this time.

Artificial intelligence presents challenges that can impact our business by posing security risks to confidential or proprietary information and personal data.

The use of artificial intelligence, combined with an uncertain regulatory environment, may result in reputational harm, liability, or other adverse consequences to our business operations. We may adopt and integrate artificial intelligence tools into our systems for specific use cases after review by our Legal and Information Security teams. Our vendors and third-party partners may incorporate artificial intelligence tools into their offerings with or without disclosing this use to us. The providers of these artificial intelligence tools may not meet existing or rapidly evolving regulatory or industry standards concerning privacy and data protection, which may result in a loss of intellectual property or confidential information and/or cause harm to our reputation and the public perception of the effectiveness of our security measures. Further, bad actors around the world use increasingly sophisticated methods, including the use of artificial intelligence, to engage in illegal activities involving the theft and misuse of personal information, confidential information and intellectual property. Any of these outcomes could damage our reputation, result in the loss of valuable property and information and adversely impact our business.

Financial Risks

Macroeconomic conditions and our credit agreement could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry, inhibit us from making beneficial acquisitions, adversely impact our ability to implement our capital allocation strategy and prevent us from making debt service payments. In addition, changing or increasing interest rates, including the rates under our debt agreements, could adversely affect our business or financial condition.

Our ability to generate sufficient cash flow from operations to make scheduled payments on our debt will depend on a range of economic, competitive and business factors, many of which are outside our control. Our business may not generate sufficient cash flow from operations to meet our debt service and other obligations, and currently anticipated cost savings and operating improvements may not be realized on schedule, or at all. If we are unable to meet our expenses and debt service and other obligations, we may need to refinance all or a portion of our indebtedness on or before maturity, sell assets or raise equity. We may not be able to refinance any of our indebtedness, sell assets or raise equity on commercially reasonable terms or at all, which could cause us to default on our obligations and impair our liquidity. Our inability to generate sufficient cash flow to satisfy our debt obligations or to refinance our obligations on commercially reasonable terms would have a material adverse effect on our business, financial condition, results of operations and cash flows. Our indebtedness could also have other important consequences with respect to our ability to manage and grow our business successfully.

Also, in spite of the limitations in our credit agreement, we may still incur significantly more debt, which could intensify the risks described above on our business, results and financial condition. For more information about our indebtedness, see Item 8, Note 10, Long-Term Debt.

The agreements governing our financing arrangements impose certain operating and financial restrictions, which could have a material adverse effect on our business, financial condition, results of operations or cash flows.

Our credit agreement contains various covenants that limit or prohibit our ability (subject to certain exceptions), among other things, to:

•incur or guarantee additional indebtedness;

•pay dividends on our common stock or redeem, repurchase, retire or make distributions in respect of our common stock or subordinated indebtedness or make other restricted payments;

•make certain loans, acquisitions, capital expenditures or investments;

•sell certain assets, including stock of our subsidiaries;

•enter into sale and leaseback transactions;

•create or incur liens;

•consolidate, merge, sell, transfer or otherwise dispose of all or substantially all of our assets; and

•enter into certain transactions with our affiliates.

These agreements contain covenants that restrict our ability to take certain actions, such as incurring additional debt, if we are unable to meet defined specified financial ratios, which could result in limiting our long-term growth prospects by hindering our ability to incur future indebtedness or grow through acquisitions. Failure to comply with certain covenants in

these agreements could result in a default. For more information, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.

The restrictions contained in the credit agreement could:

•limit our ability to plan for or react to market conditions or meet capital needs or otherwise restrict our activities or business plans;

•restrict our ability to repurchase shares of our common stock and/or adversely impact our ability to implement capital allocation strategy;

•adversely affect our ability to finance our operations, to enter into strategic acquisitions, to fund investments or other capital needs or to engage in other business activities that would be in our interest; and

•limit our access to the cash generated by our subsidiaries.

Upon the occurrence of an event of default under the credit agreement, the lenders could elect to declare all amounts outstanding under the senior secured credit facilities to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, the lenders under the senior secured credit facilities could proceed against the collateral granted to them to secure the senior secured credit facilities on a first-priority lien basis. If the lenders under the senior secured credit facilities accelerate the repayment of borrowings, such acceleration could have a material adverse effect on our business, financial condition, results of operations or cash flows. For a more detailed description of the limitations on our ability to incur additional indebtedness, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.

Our goodwill and intangible assets are valued at an amount that is high relative to our total assets and in excess of our stockholders' equity.

As of December 31, 2025, our goodwill and intangible assets totaled $795.0 million and $835.0 million, respectively, and represent a substantial portion of our assets. These assets result from our acquisitions, representing the excess of cost over the fair value of the tangible net assets we have acquired. We assess at least annually whether there has been impairment in the value of our goodwill and indefinite-lived intangible assets. Significant negative industry or economic trends, disruptions to our business, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes to the use of our assets, changes in the structure of our business, divestitures, market capitalization declines, or increases in associated discount rates may impair our goodwill and other intangible assets. Any determination requiring the impairment of goodwill or intangible assets would negatively affect our results of operations, particularly in the period in which we record any related charges, and financial condition.

Our required cash contributions or plan settlement expense related to our pension plans may increase and we could experience a change in the funded status of our defined benefit pension plans and the amount recorded in our consolidated balance sheets related to those plans. Additionally, pension costs could increase in future years.

In 2025, the Company terminated its U.S. defined benefit pension plan (the "Pension Plan"). The plan termination is subject to regulatory review and requirements, which may result in additional funding. See Item 8, Note 14, Retirement Benefits for additional details. In addition, the Company still maintains other domestic and international (statutory) defined benefit plans.The funded status of the defined benefit pension plans depends on such factors as asset returns, market interest rates, legislative changes and funding regulations. If the returns on the assets of any of our plans were to decline in future periods, if market interest rates were to decline, if the Pension Benefit Guaranty Corporation ("PBGC") were to require additional contributions to any such plans as a result of acquisitions or if other actuarial assumptions were to be modified, our future required cash contributions and pension costs to such plans could increase. Any such increases could have an adverse effect on our business, financial condition, results of operations or cash flows.

The need to make contributions to such plans may reduce the cash available to meet our other obligations, including our obligations under our borrowing arrangements or to meet the needs of our business.

Legal and Compliance Risks

Our failure to comply with government regulations and requirements, third-party certification requirements and policies and standards driven by our customers or other constituencies, including those related to social responsibility, could adversely affect our reputation, business and results of operations.

In addition to complying with laws and applicable government regulations and requirements, prevailing industry standards, competitive pressures and/or our customers may require us to comply with further quality, social responsibility, climate-related or other business policies or standards, before customers and prospective customers commence, or continue, doing business with us. These expectations, policies and standards may be more restrictive than current laws and regulations as

well as our own pre-existing policies; they may be customer-driven, established by the industry sectors in which we operate or imposed by third-party organizations or other constituencies.

Our compliance with these policies, standards and third-party certification requirements could be costly and could in some cases require us to change the way in which we operate. In addition, if we fail to comply, or if our compliance increases our costs and/or restricts our ability to do business as compared to our competitors that do not adhere to such standards, we could experience an adverse effect on our customer relationships, reputation, operations, cost structure and/or profitability.

Regulatory and legislative developments related to climate change, may materially adversely affect our business and financial condition.

Numerous governmental bodies have introduced or are contemplating legislative and regulatory changes in response to various climate change interest groups and the impact of climate change.Legislation and increased regulation relating to climate change and the transition to a low carbon economy could impose significant costs on us and our suppliers, including costs related to increased energy requirements, capital equipment, environmental monitoring and reporting, and other costs to comply with such regulations. Any future climate change-related regulations could also negatively impact our ability to compete with companies situated in areas not subject to such requirements. Given the political significance and uncertainty around the impact of climate change and how it should be addressed, we cannot predict how legislation and regulation will affect our financial condition, operating performance and ability to compete. Furthermore, even without such regulation, increased awareness and any adverse publicity in the global marketplace about impacts on climate change by us could harm our reputation. Any of the foregoing could result in a material adverse effect on our business and financial condition.

We are subject to changes in legislative, regulatory and legal developments involving taxes.

We are subject to U.S. federal and state, and foreign, income, payroll, property, sales and use, value-added, fuel and other types of taxes. Changes in tax rates, enactment of new tax laws, revisions of tax regulations, and claims or litigation with taxing authorities may require significant judgment in determining the appropriate provision and related accruals for these taxes; and as a result, such changes could result in substantially higher taxes and, therefore, could have a significant adverse effect on our results or operations, financial conditions and liquidity.

In October 2021, the Organization for Economic Co-operation and Development (“OECD”) issued rules for a new global minimum tax (“Pillar 2”), which included the introduction of a 15% global minimum tax (“Top-Up Tax”) that applies to tax years beginning in 2024. To date, approximately 140 countries have signed a framework agreeing to implement Pillar 2. Based upon the current OECD rules and administrative guidance, as well as the related legislation of those countries in which we do business, the Company does not anticipate being subject to material Top-Up Taxes. The Company is continuing to monitor the potential impact of the Pillar 2 proposals and developments on our consolidated financial statements and related disclosures, including eligibility for any transitional safe harbor rules.

On July 4, 2025, the U.S. government enacted the One Big Beautiful Bill Act (“OBBBA”). OBBBA extended several provisions of the Tax Cuts and Jobs Act (“TCJA”) of 2017 that were set to expire on December 31, 2025, including immediate expensing of domestic research and development expenses, 100% bonus depreciation, qualified production property 100% depreciation, and reinstatement of utilizing EBITDA for the interest deduction limitation. The OBBBA incorporates additional changes to the U.S tax code that will be effective after January 1, 2026, including charitable contribution limitations, deductible meal limitations, and changes to the U.S. system for taxing international corporate income. We expect to continue to see future regulatory, administrative or legislative guidance. The full extent of the impact remains uncertain at this time, and our current interpretations of, and assumptions regarding, OBBBA are subject to additional regulatory or administrative developments, including any regulations or other guidance promulgated by the U.S. Internal Revenue Service (“IRS”).

We may incur significant costs for environmental compliance and/or to address liabilities under environmental laws and regulations, and our reputation may be adversely affected.

Our operations and facilities worldwide are subject to extensive laws and regulations related to pollution and the protection of the environment, health and safety, including those governing, among other things, emissions to air, discharges to water, the generation, handling, storage, treatment and disposal of hazardous wastes and other materials, and the remediation of contaminated sites. A failure by us to comply with applicable requirements or the permits required for our operations could result in civil or criminal fines, penalties, enforcement actions, third-party claims for property damage and personal injury, requirements to clean up property or to pay for the costs of cleanup or regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, including the installation of pollution control equipment or remedial actions, as well as cause damage to our reputation.

Some environmental laws and regulations impose requirements to investigate and remediate contamination on present and former owners and operators of facilities and sites, and on potentially responsible parties ("PRPs") for sites to which such parties may have sent waste for disposal. Such liability can be imposed without regard to fault and, under certain circumstances,

may be joint and several, resulting in one PRP being held responsible for the entire obligation. Liability may also include damages to natural resources. On occasion we are involved in such investigations and/or cleanup, and also have been or could be named as a PRP in environmental matters.

The discovery of additional contamination, including at acquired facilities, the imposition of more stringent environmental, health and safety laws and regulations, including cleanup requirements, disputes with our insurers or the insolvency of other responsible parties could require us to incur significant capital expenditures or operating costs materially in excess of our accruals. Future investigations we undertake may lead to discoveries of contamination that must be remediated, and decisions to close facilities may trigger remediation requirements that are not currently applicable. We may also face liability for alleged personal injury or property damage due to exposure to hazardous substances used or disposed of by us, contained within our current or former products, or present in the soil or groundwater at our current or former facilities. We could incur significant costs in connection with such liabilities. See Item 8, Note 16, Commitments and Contingencies for additional information.

Certain subsidiaries are subject to litigation, including product liability and other claims, which could adversely affect our business, reputation, financial condition, results of operations or cash flows.

We may be subject to product liability and other claims if the use of our products, or the exposure to our products or their raw materials, is alleged to have resulted in injury or other adverse effects. We currently maintain product liability insurance coverage but we cannot assure that we will be able to obtain such insurance on commercially reasonable terms in the future, if at all, or that any such insurance will provide adequate coverage against claims. Litigation and product liability claims can be expensive to defend and can divert the attention of management and other personnel for long periods of time, regardless of the ultimate outcome. In addition, our business depends on the strong brand reputation we have developed; if this reputation is damaged as a result of litigation or product liability claims, it may be difficult to maintain our pricing positions and market share with respect to our products. Therefore, an unsuccessful litigation matter or product liability defense could have a material adverse effect on our business, financial condition, results of operations or cash flows. See Item 8, Note 16, Commitments and Contingencies for additional details.

Our inability to achieve our sustainability strategy goals and targets could adversely impact our business, financial condition, results of operations or cash flows.

Achieving our sustainability strategy goals and targets included in our annual Sustainability Report may be impacted by factors such as availability of resources, technological advances, legislative and regulatory changes, and customer or supplier requirements, many of which are not in our control. We are committed to meeting these goals and targets, however, the inability to do so could adversely impact our business or financial condition. Also, changing standards for measuring and reporting on applicable sustainability metrics could result in increased costs and adversely impact our results of operations or cash flows. Additionally, if our sustainability strategy and initiatives are misaligned with evolving stakeholder expectations, it could negatively impact our reputation.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

None.

ITEM 1C. CYBERSECURITY.

Zurn Elkay’s management and Board recognize the importance of robust oversight of cybersecurity risk, information security, and technology risk in maintaining the trust and confidence of our customers, partners, employees, and stockholders. The Audit Committee, on behalf of the Board, oversees the Company’s material financial and other risk exposures, including risks related to cybersecurity and artificial intelligence. Our Board has extensive cybersecurity experience, including two members of the Audit Committee who have received a certificate in cybersecurity oversight from the Carnegie Mellon University Software Engineering Institute and one member of the Audit Committee who received a certificate in Effective AI Oversight from the Heinz College of Information Systems and Public Policy of Carnegie Mellon University.Cybersecurity risk also is monitored, assessed and managed as part of the Company’s integrated Enterprise Risk Management program.A cybersecurity governance council, comprised of executive leaders, including the two members of the Audit Committee with cybersecurity experience, meets at least quarterly to review the Company’s cybersecurity program and its effectiveness. This cybersecurity governance council receives updates and reports from the Company’s global cybersecurity team (discussed below) on the cybersecurity program and its effectiveness relating to the prevention, detection, mitigation and remediation of cybersecurity incidents. The Chief Information Officer (CIO) provides periodic updates to the Audit Committee on any material initiatives and key updates on the cybersecurity program and its effectiveness, including any material threats. The CIO also provides an annual update regarding information security to the full Board.The CIO has more than 37 years of information technology experience, including approximately 19 years serving as a CIO.

To assess, identify and manage material risks from cybersecurity threats and to prevent, detect and respond to cybersecurity threats, including threats associated with the use of third-party service providers, the Company has a robust cybersecurity program.The Company’s global cybersecurity team, overseen by the CIO, implements policies and procedures and uses a balanced approach to validate the effectiveness of the program, leveraging third party expert security resources, information technology resources, executive business leadership, internal and external audit, third-party vendors and other IT and business partners. The program uses a combination of standards and best practices from the National Institute of Standards and Technology, Center of Internet Security, third-party vendor partners, and other industry forums. The program is assessed both internally and externally, including a thorough industry benchmarking and best practice review annually, with maturity assessments and risk assessments occurring alternating years biennially. Control validations occur monthly internally (focused on core critical controls), quarterly (focused on vulnerabilities/cyber-incident simulations) and annually (focused on a review of best practices) via third-party vendors and partners, and annually via external third parties, including the conduct of internal/external penetration tests and tabletop exercises. Third-party service providers are assessed initially based on security questionnaires and the access of third-party service providers is audited annually and/or with any change in circumstances. Third-party service provider access is also monitored through a combination of security information and event management technology and managed detection response services. The CIO provides key results and findings from these assessments to the cybersecurity governance council and Audit Committee. The Company has a robust incident response plan intended to help provide timely remediation to cybersecurity incidents and also to help provide notice of any material incidents to the appropriate internal and external entities.

To help associates acquire the knowledge to support the protection of our environment, the Company provides comprehensive annual security awareness training, periodic information updates, and regular testing/training programs. In addition, the Company annually purchases a cybersecurity insurance policy.

The Company depends heavily on information technology infrastructure to manage our business objectives and operations, support our customers’ requirements and protect sensitive information. To date, the Company has not experienced a cybersecurity threat or cybersecurity incident that has materially affected the Company, including our business strategy, results of operations or financial condition. While the Company has a robust cybersecurity program in place and has taken steps to maintain and enhance its cybersecurity, a material security breach could impede the Company’s ability to carry on business in the normal course. As we have previously described in Item 1A, Risk Factors, there have been significant and increasing instances of data and security breaches, malicious interference with technology systems and industrial espionage involving companies in numerous industries, including cloud providers, and cybersecurity threats are becoming more complex. In addition, at times a large percentage of our workforce may be working remotely, which may heighten these risks. While we have taken steps to maintain and enhance our cybersecurity by implementing additional security technologies, internal controls, network and data center resiliency, redundancy and disaster recovery processes and backup systems, upgrading our remote work environment and by obtaining insurance coverage, these measures may be inadequate and our technology systems could be vulnerable to disability, failures or unauthorized access. As a result, any inability by us to successfully manage our information systems, or respond effectively to any attack on or interference with our systems, including matters related to system and data security, privacy, reliability, compliance, performance and access, problems related to our systems caused by natural disasters, security breaches or malicious attacks, misuse of artificial intelligence tools, and any inability of these systems to fulfill their intended business purpose, could impede our ability to record or process orders, manufacture and ship in a timely manner, account for and collect receivables, protect sensitive data of the Company, our customers, our employees, our suppliers and other business partners, comply with our third party obligations of confidentiality and care, or otherwise carry on business in the normal course. Any such events could require costly remediation beyond levels covered by insurance and could cause us to lose customers and/or revenue, including as a result of legal or regulatory claims or proceedings, or damage our reputation, any of which could have a material adverse effect on our business and operating results.

Refer to Item 1, Business for additional information.

Financial Statement Presentation

The following paragraphs provide a brief description of certain items and accounting policies that appear in our financial statements and general factors that impact these items.

Net sales. Net sales represent gross sales less deductions taken for sales returns and allowances and incentive rebate programs.

Cost of sales. Cost of sales includes all costs of manufacturing required to bring a product to a ready for sale condition. Such costs include direct and indirect materials, direct and indirect labor costs, including fringe benefits, supplies, utilities, depreciation, freight and shipping, insurance, pension and other postretirement benefits, information technology costs and other manufacturing related costs.

The largest component of our cost of sales is cost of materials, which represented approximately 30% of net sales in the year ended December 31, 2025. We purchase a broad range of materials and components throughout the world in connection with our manufacturing activities. Major raw materials and components include bronze, iron, brass, stainless steel, carbon steel, zinc, and engineered plastics. We have a strategic sourcing program that is designed to significantly reduce the number of direct and indirect suppliers we use and to lower the cost of purchased materials.

Selling, general and administrative expenses. Selling, general and administrative expenses primarily include sales and marketing, finance and administration, engineering and technical services and warehousing. Our major cost elements include salary and wages, fringe benefits, insurance, depreciation, advertising, travel and information technology costs.

Critical Accounting Estimates

The methods, estimates and judgments we use in applying our critical accounting policies have a significant impact on the results we report in our consolidated financial statements. We evaluate our estimates and judgments on an on-going basis. We base our estimates on historical experience and on assumptions that we believe to be reasonable under the circumstances. Our experience and assumptions form the basis for our judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may vary from what we anticipate and different assumptions or estimates about the future could change our reported results. Within the context of these critical accounting policies, we are not currently aware of any reasonably likely event that would result in materially different amounts being reported.

We believe the following accounting policies are the most critical to us in that they are important to our financial statements and they require difficult, subjective and/or complex judgments in the preparation of our consolidated financial statements. For additional information, see Item 8, Note 2, Significant Accounting Policies, to our consolidated financial statements.

Purchase accounting and business combinations. Assets acquired and the liabilities assumed as part of a business combination are recognized separately from goodwill at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. We review and consider input from outside specialists, if and when appropriate to develop discount rates, and use estimates and assumptions about the future performance of the business to accurately value assets acquired and liabilities assumed at the acquisition date. We may refine these estimates during the measurement period, which may be up to one year from the acquisition date. As a result, during the measurement period, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset recorded to goodwill. Upon the conclusion of the measurement period or final determination of the values of the assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in our consolidated statements of operations.

Impairment of intangible assets and tangible fixed assets. The carrying value of long-lived assets, including amortizable intangible assets and tangible fixed assets, are evaluated for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Impairment of amortizable intangible assets and tangible fixed assets is generally determined by comparing projected undiscounted cash flows to be generated by the asset, or group of assets, to its carrying value. If impairment is identified, a loss is recorded equal to the excess of the asset's net book value over its fair value, and the cost basis is adjusted. Determination of the fair value requires various estimates including internal cash flow estimates generated from the asset, quoted market prices and appraisals as appropriate to determine fair value. Actual results could vary from these estimates. During the years ended December 31, 2025, 2024, and 2023, the Company recognized $2.0 million, $7.4 million, and $2.5 million of fixed asset impairment charges, respectively.

Goodwill, trademarks and certain tradenames have indefinite lives and are not amortized. However, the goodwill and intangible assets are tested annually for impairment, and may be tested more frequently if any triggering events occur that would reduce the recoverability of the asset. In conducting the annual impairment test for goodwill, we have the option to first assess qualitative factors to determine whether it is more likely than not (greater than 50% likelihood) the fair value of any reporting unit is less than its carrying amount. If a qualitative assessment determines an impairment is more likely than not, we are required to perform a quantitative impairment test. Otherwise, no further analysis is required. Alternatively, we may elect to proceed directly to the quantitative impairment test. In conducting a quantitative assessment, we use a discounted cash flow methodology based on future business projections and a market value approach (guideline public company comparables). We perform our goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. If the carrying amount exceeds the fair value of the reporting unit, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value up to the amount of the recorded goodwill.

During the fourth quarter of the year ended December 31, 2025, we completed our annual goodwill and intangible asset impairment tests and elected to perform a qualitative assessment. No goodwill impairment charges were recorded during the years ended December 31, 2025, 2024, or 2023. During the year ended December 31, 2024, we recorded a $0.6 million impairment charge related to an indefinite-lived tradename no longer used. No intangible asset impairment charges were recorded during the years ended December 31, 2025 or 2023.

Retirement benefits. We have pension and post-retirement benefit income and expense and assets/liabilities that are developed from actuarial valuations. These valuations include key assumptions regarding discount rates, expected return on plan assets, mortality rates, compensation increases, and the current health care cost trend rate. We consider current market conditions in selecting these assumptions. Changes in the related pension and post-retirement benefit income/costs or assets/liabilities may occur in the future due to changes in the assumptions and changes in asset values. As described in Note 14 to the consolidated financial statements, the Company’s Board of Directors approved a resolution to terminate the Company’s U.S. defined benefit pension plan (the “Pension Plan”) with the full freeze of benefit accruals under the Pension Plan effective March 31, 2025 and the termination of the Pension Plan effective April 1, 2025.

The Company remeasures the pension assets and obligations at the end of each year or more frequently upon any required remeasurement event. The amounts are measured using actuarial valuations, which are dependent, in part, on the selection of certain actuarial assumptions. Measuring the pension obligations was complex and required the involvement of specialists as a result of the complex nature of the actuarial assumptions, such as discount rates and mortality rates used in the Company’s accounting of the U.S. defined benefit pension plan termination and the related remeasurement process. These assumptions had a significant effect on the projected benefit obligation used to calculate to pension settlement gain.

We recognize the net actuarial gains or losses in excess of unrecognized gain or loss exceeding 10 percent of the greater of the market-related value of plan assets or the plan's projected benefit obligation at re-measurement (the "corridor") in our consolidated statements of operations during the fourth quarter of each fiscal year (or upon any re-measurement date). During the years ended December 31, 2025, 2024, and 2023, we recognized a non-cash actuarial gain from continuing operations of $0.5 million, $1.4 million, and $2.0 million, respectively, in connection with re-measurements of our plans. Net periodic benefit costs recorded on a quarterly basis are primarily comprised of service and interest cost and the expected return on plan assets. See Item 8, Note 14, Retirement Benefits for additional information.

The obligation for other postretirement benefits other than pension also is actuarially determined and is affected by assumptions including the discount rate and expected future increase in per capita costs of covered other postretirement health care benefits. Changes in the discount rate and differences between actual and assumed per capita health care costs may affect the recorded amount of the expense in future periods.

Income taxes. We are subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes and recording the related deferred tax assets and liabilities. In October 2021, the Organization for Economic Co-operation and Development (“OECD”) issued rules for a new global minimum tax (“Pillar 2”) which included the introduction of a 15% global minimum tax (“Top-Up Tax”) that applies to tax years beginning in 2024. Based upon the current OECD rules and administrative guidance, as well as the related legislation

of those countries in which we do business, the Company does not anticipate being subject to material Top-Up Taxes. The Company is continuing to monitor the potential impact of the Pillar 2 proposals and development on our consolidated financial statements and related disclosures, including eligibility for any transitional safe harbor rules. On July 4, 2025, the U.S. enacted the One Big Beautiful Bill Act (“OBBBA”). OBBBA incorporates changes that extend several provisions of the Tax Cuts and Jobs Act (“TCJA”) of 2017 that were set to expire on December 31, 2025, including immediate expensing of domestic research and development expenses, 100% bonus depreciation, 100% depreciation of qualified production property, and reinstatement of utilizing EBITDA for the interest deduction limitation. These changes are effective for the Company’s fiscal year ending December 31, 2025. The Company is continuing to monitor these business tax provisions for further guidance from the U.S. Treasury and the Internal Revenue Service.

We assess our income tax positions and record tax liabilities for all years subject to examination based upon management’s evaluation of the facts and circumstances and information available at the reporting dates. For those income tax positions where it is more-likely-than-not, based on technical merits, that a tax benefit will be sustained upon the conclusion of an examination, we have recorded the largest amount of tax benefit having a cumulatively greater than 50% likelihood of being realized upon ultimate settlement with the applicable taxing authority, assuming that it has full knowledge of all relevant information. For those tax positions which do not meet the more-likely-than-not threshold regarding the ultimate realization of the related tax benefit, no tax benefit has been recorded in the financial statements. In addition, we provide for interest and penalties, as applicable, and record such amounts as a component of the overall income tax provision. As of December 31, 2025 and 2024, our liability for unrecognized tax benefits was $0.6 million and $1.8 million, respectively.

We recognize deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities, net operating losses (“NOLs”), tax credit and other carryforwards. We regularly review our deferred tax assets for recoverability and establish a valuation allowance based on historical losses, projected future taxable income and the expected timing of the reversals of existing temporary differences. As a result of this review, we established a full valuation allowance against U.S. federal and state capital loss carryforwards, as well as certain foreign NOL carryforwards and related deferred tax assets, and continue to maintain a partial valuation allowance against certain U.S. state NOL and tax credit carryforwards. As of December 31, 2025 and 2024, valuation allowances of $4.8 million and $9.0 million, respectively, were recorded against our deferred tax assets. See Item 8, Note 15, Income Taxes for additional information.

Commitments and Contingencies. We are subject to proceedings, lawsuits and other claims related to environmental, labor, product and other matters. We are required to assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. We determine the amount of accruals needed, if any, for each individual issue based on our professional knowledge and experience and discussions with legal counsel. The required accruals may change in the future due to new developments in each matter, the ultimate resolution of each matter or changes in approach, such as change in strategy. See Item 8, Note 16, Commitments and Contingencies for additional information.

Recent Accounting Pronouncements

See Item 8, Note 2, Significant Accounting Policies regarding recent accounting pronouncements.

Overview of Recent Developments

U.S. Pension Plan Termination & Settlement

On January 30, 2025, the Company's Board of Directors approved a resolution to terminate the Company's U.S. defined benefit pension plan (the "Pension Plan") with the full freeze of benefit accruals under the Pension Plan effective March 31, 2025 and the termination of the Pension Plan effective April 1, 2025. The Pension Plan freeze resulted in a curtailment gain of $0.7 million in the first quarter of 2025. Pension Plan participants were provided the opportunity to receive their full accrued benefits from the Pension Plan assets by either electing immediate lump sum distributions or annuity contracts with a qualifying third-party annuity provider. During the quarter ended September 30, 2025, the Company entered into an agreement to purchase annuities from a third-party annuity provider and contributed $4.3 million to fund the liquidation of the Pension Plan. As a result, Pension Plan liabilities were settled and the Pension Plan was exited during the quarter ended September 30, 2025, resulting in a pre-tax settlement gain of $10.0 million from accumulated other comprehensive loss to other income (expense), net in the consolidated statements of operations.

Divestiture of Asbestos Liabilities and Certain Assets

On December 15, 2023, Zurn Holdings, Inc. (“Holdings”) sold all of the equity interests of its direct subsidiary Zurn Industries, LLC (“Zurn Industries”), together with Zurn Industries’ direct and indirect subsidiaries that primarily held asbestos liabilities, certain assets and cash, in a stock sale transaction to an unaffiliated buyer (“Sale Transaction”). As a result of the Sale Transaction, all asbestos obligations and liabilities, related insurance assets and associated deferred taxes, and other assets sold to the buyer, have been removed from the Company’s consolidated balance sheet effective December 15, 2023 and the Company no longer has any obligation with respect to pending and future asbestos claims related to the divested entities. A loss on the divestiture of asbestos liabilities and certain assets of $11.4 million was recognized in the consolidated statements of operations for the twelve months ended December 31, 2023.

Discontinued Operations

During the year ended December 31, 2021, we completed the spin-off of our PMC platform. The operating results of PMC are reported as discontinued operations in our consolidated statements of operations for all periods presented, as the Spin-Off Transaction represented a strategic shift that had a major impact on our operations and financial results. The consolidated statements of cash flows for the years ended December 31, 2025, 2024, and 2023 have not been adjusted to separately disclose cash flows related to the discontinued operations.

The major components of the Income from discontinued operations, net of tax presented in the consolidated statements of operations during the years ended December 31, 2025, 2024, and 2023 are included in the table below (in millions):

Year Ended

Selling, general and administrative income (1) (4.7) (0.7) (8.4)

Income from discontinued operations before income tax 4.7 0.7 8.4

Income from discontinued operations, net of tax $ 5.6 $ 1.3 $ 8.5

_________________

(1)Selling, general and administrative income for the years ended December 31, 2025, 2024, and 2023 includes the release of certain accruals as a result of costs the Company will no longer incur related to the Spin-Off Transaction.

See Item 8, Note 3, Discontinued Operations for more information.

Restructuring and Other Similar Charges

During the year ended December 31, 2025, we continued to execute various restructuring actions. These initiatives were intended to drive efficiencies and reduce operating costs while also modifying our footprint to reflect changes in the markets we serve, the impact of acquisitions on our overall manufacturing capacity and the refinement of our overall product portfolio. These restructuring actions primarily resulted in workforce reductions, lease termination costs, and other facility rationalization costs. We expect to continue executing similar initiatives to optimize our operating margin and manufacturing footprint. As such, we expect further expenses related to workforce reductions, potential impairment of assets, lease termination costs, and other facility rationalization costs.

We recorded restructuring charges of $9.6 million, $13.5 million and $15.3 million for the years ended December 31, 2025, 2024, and 2023, respectively. See Item 8, Note 4, Restructuring and Other Similar Charges for more information.

Results of Operations

Year Ended December 31, 2025 Compared with the Year Ended December 31, 2024

Net sales

(Dollars in Millions)

Year Ended

Net sales were $1,695.9 million for the year ended December 31, 2025, a 8.3% increase year over year. Core sales grew of 8% year over year, including growth in all product categories.

Income from operations

(Dollars in Millions)

Year Ended

Income from operations was $278.9 million for the year ended December 31, 2025, or 16.4% of net sales, compared to income from operations of $244.6 million, or 15.6% of net sales, for the year ended December 31, 2024. Income from operations as a percentage of net sales increased by 80 basis points year over year as a result of the favorable impact of year-over-year sales growth (inclusive of price realization) and productivity savings being offset primarily by the adjustment to state inventories at Last-In, First-Out ("LIFO") cost.

Interest expense, net

Interest expense, net was $28.6 million for the year ended December 31, 2025 compared to $33.1 million for the year ended December 31, 2024. The decrease in interest expense, net as compared to the prior year period is primarily due to lower interest rates.

Actuarial gain on pension and other postretirement benefit obligations

Actuarial gain on pension and other postretirement benefit obligations for the year ended December 31, 2025, was $0.5 million compared to a gain of $1.4 million for the year ended December 31, 2024. The non-cash actuarial gain recognized for the year ended December 31, 2025 was primarily due to demographic and claims gains experienced during 2025 that were reflected in certain other post-retirement benefit plans. The non-cash actuarial gain recognized for the year ended December 31, 2024, was primarily due to a combination of discount rate increases coupled with demographic and claims gains experienced during 2024 that were reflected in the other post-retirement benefit plans. These gains were partially offset by an increase in the medical cost growth assumption from the prior measurement. See Item 8, Note 14, Retirement Benefits for more information.

Other income (expense), net

Other income (expense), net for the year ended December 31, 2025, was $5.5 million compared to other income (expense), net of $(5.9) million for the year ended December 31, 2024. Other income (expense), net consists primarily of foreign currency transaction gains and losses, the non-service cost components associated with our defined benefit plans and other non-operational gains and losses. The year-over-year change is primarily driven by the gain resulting from the settlement and termination of our U.S. defined benefit pension plan in the current year.

Provision for income taxes

The income tax provision for the year ended December 31, 2025 was $63.9 million, or an effective tax rate of 24.9%. The effective income tax rate for the year ended December 31, 2025 was above the U.S. federal statutory rate of 21% primarily due to the accrual of additional income taxes associated with compensation deduction limitations under Section 162(m) of the Internal Revenue Code, the accrual of various state income taxes and the accrual of foreign income taxes, which are generally

above the U.S. federal statutory rate, partially offset by the recognition of income tax benefits associated with share-based payments and the recognition of certain previously unrecognized tax benefits due to the lapse of the applicable statutes of limitations. The income tax provision for the year ended December 31, 2024 was $48.1 million, or an effective tax rate of 23.2%. The effective income tax rate for the year ended December 31, 2024 was above the U.S. federal statutory rate of 21% primarily due to the accrual of additional income taxes associated with compensation deduction limitations under Section 162(m) of the Internal Revenue Code, the accrual of various state income taxes and the accrual of foreign income taxes, which are generally above the U.S. federal statutory rate, partially offset by the recognition of income tax benefits associated with share-based payments and the recognition of certain previously unrecognized tax benefits due to the lapse of the applicable statutes of limitations.

Net income from continuing operations

Our net income from continuing operations for the year ended December 31, 2025, was $192.4 million, compared to net income from continuing operations of $158.9 million for the year ended December 31, 2024, as a result of the factors described above. Diluted net income per share from continuing operations was $1.12 per share for the year ended December 31, 2025, as compared to $0.91 per share for the year ended December 31, 2024.

Net income

Net income for the year ended December 31, 2025, was $198.0 million compared to $160.2 million for the year ended December 31, 2024. Diluted net income per share was $1.15 per share for the year ended December 31, 2025, compared to $0.92 per share for the year ended December 31, 2024. Income from discontinued operations, net of tax, was $5.6 million for the year ended December 31, 2025 compared to $1.3 million for the year ended December 31, 2024. The year-over-year change in net income is primarily the result of the factors described above.

Non-GAAP Financial Measures

Non-GAAP financial measures are intended to supplement and not replace financial measures prepared in accordance with GAAP. The following non-GAAP financial measures are utilized by management in comparing our operating performance on a consistent basis. We believe that these financial measures are appropriate to enhance an overall understanding of our underlying operating performance trends compared to historical and prospective periods and our peers. Management also believes that these measures are useful to investors in their analysis of our results of operations and provide improved comparability between fiscal periods as well as insight into the compliance with our debt covenants. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information calculated in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures.

Core sales

Core sales excludes the impact of mergers and acquisitions, divestitures and foreign currency translation. Management believes that core sales facilitates easier and more meaningful comparisons of our net sales performance with prior and future periods and to our peers. We exclude the effect of mergers and acquisitions and divestitures because the nature, size and number of mergers and acquisitions and divestitures can vary dramatically from period to period and between us and our peers, and can also obscure underlying business trends and make comparisons of long-term performance difficult. We exclude the effect of foreign currency translation from this measure because the volatility of currency translation is not under management's control.

EBITDA

EBITDA represents earnings before interest and other debt related activities, taxes, depreciation and amortization. EBITDA is presented because it is an important supplemental measure of performance and it is frequently used by analysts, investors and other interested parties in the evaluation of companies in our industry. EBITDA is also presented and compared by analysts and investors in evaluating our ability to meet debt service obligations. Other companies in our industry may calculate EBITDA differently. EBITDA is not a measurement of financial performance under U.S. GAAP and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or an alternative to net income as indicators of operating performance or any other measures of performance derived in accordance with U.S. GAAP. Because EBITDA is calculated before recurring cash charges, including interest expense and taxes, and is not adjusted for capital expenditures or other recurring cash requirements of the business, it should not be considered as a measure of discretionary cash available to invest in the growth of the business.

Adjusted EBITDA

Adjusted EBITDA is an important measure because, under our credit agreement, our ability to incur certain types of acquisition debt and certain types of subordinated debt, make certain types of acquisitions or asset exchanges, operate our business and make dividends or other distributions, all of which will impact our financial performance, is impacted by our Adjusted EBITDA, as our lenders measure our performance with a Net First Lien Leverage Ratio by comparing our senior secured bank indebtedness to our Adjusted EBITDA (see "Covenant Compliance" for additional discussion of this ratio, including a reconciliation to our net income). "Adjusted EBITDA" is the term we use to describe EBITDA as defined and adjusted in our credit agreement, which is net income, adjusted for the items summarized in the table in the Covenant Compliance section. Adjusted EBITDA is intended to show our unleveraged, pre-tax operating results and therefore reflects our financial performance based on operational factors, excluding non-operational, non-cash or non-recurring losses or gains. It is also provided to aid investors in understanding our compliance with our debt covenants. Adjusted EBITDA is not a presentation made in accordance with GAAP, and our use of the term Adjusted EBITDA varies from others in our industry. This measure should not be considered as an alternative to net income, income from operations or any other performance measures derived in accordance with GAAP. Adjusted EBITDA has important limitations as an analytical tool, and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. For example, Adjusted EBITDA does not reflect: (a) our capital expenditures, future requirements for capital expenditures or contractual commitments; (b) changes in, or cash requirements for, our working capital needs; (c) the significant interest expenses, or the cash requirements necessary to service interest or principal payments, on our debt; (d) tax payments that represent a reduction in cash available to us; (e) any cash requirements for the assets being depreciated and amortized that may have to be replaced in the future; or (f) the impact of earnings or charges resulting from matters that we and the lenders under our credit agreement may not consider indicative of our ongoing operations. In particular, our definition of Adjusted EBITDA allows us to add back certain non-cash, non-operating or non-recurring charges that are deducted in calculating net income, even though these are expenses that may recur, vary greatly and are difficult to predict and can represent the effect of long-term strategies as opposed to short-term results.

In addition, certain of these expenses added back in calculating Adjusted EBITDA can represent the reduction of cash that could be used for other corporate purposes. Further, although not included in the calculation of Adjusted EBITDA in the Covenant Compliance section below, the measure may at times allow us to add estimated cost savings and operating synergies related to operational changes ranging from acquisitions or dispositions to restructuring, and/or exclude one-time transition expenditures that we anticipate incurring to realize cost savings before such savings have occurred.

The calculation of Adjusted EBITDA under our credit agreement as of December 31, 2025, is presented in the table in the Covenant Compliance section below. However, the results of such calculation could differ in the future based on the different types of adjustments that may be included in such respective calculations at the time. We reported net income in the year ended December 31, 2025, of $198.0 million and Adjusted EBITDA for the same period of $442.2 million. See "Covenant Compliance" for a reconciliation of Adjusted EBITDA to GAAP net income.

Covenant Compliance

Our credit agreement, which governs our senior secured credit facilities, contains, among other provisions, restrictive covenants regarding indebtedness, payments and distributions, mergers and acquisitions, asset sales, affiliate transactions, capital expenditures and the maintenance of certain financial ratios. Payment of borrowings under the credit agreement may be accelerated if there is an event of default. Events of default include the failure to pay principal and interest when due, a material breach of a representation or warranty, certain non-payments or defaults under other indebtedness, covenant defaults, events of bankruptcy and a change of control. Certain covenants contained in the credit agreement restrict our ability to take certain actions, such as incurring additional debt or making acquisitions, if we are unable to meet a maximum Net First Lien Leverage Ratio (consolidated indebtedness to Adjusted EBITDA) of 5.0 to 1.0 as of the end of each fiscal quarter. As of December 31, 2025, our Net First Lien Leverage Ratio was 0.53 to 1.0. Failure to comply with these covenants could limit our long-term growth prospects by hindering our ability to borrow under the revolver, to obtain future debt and/or to make acquisitions.

Set forth below is a reconciliation of net income to Adjusted EBITDA for the year ended December 31, 2025.

(in millions) Year Ended December 31, 2025

(3)In accordance with the terms in our credit agreement, restructuring and other similar charges is comprised of costs associated with workforce reductions, lease termination costs, and other facility rationalization costs. See Item 8, Note 4, Restructuring and Other Similar Charges for more information.

(4)Last-In, First-Out ("LIFO") adjustments are excluded in calculating Adjusted EBITDA as defined in our credit agreement.

(5)Other, net consists of gains and losses on the disposition of long-lived assets in accordance with the terms of our credit agreement.

(6)Our credit agreement defines our consolidated indebtedness as the sum of all indebtedness (other than letters of credit or bank guarantees, to the extent undrawn) consisting of indebtedness for borrowed money and capitalized lease obligations, less unrestricted cash, which was $260.4 million (as defined by the credit agreement) at December 31, 2025.

(7)Our credit agreement defines the Net First Lien Leverage Ratio as the ratio of consolidated indebtedness (as described above) to Adjusted EBITDA for the trailing four fiscal quarters.

Liquidity and Capital Resources

Our primary sources of liquidity are available cash and cash equivalents, cash flow from operations, and borrowing availability under our $200.0 million revolving credit facility.

As of December 31, 2025, we had $300.5 million of cash and cash equivalents and $189.9 million of additional borrowing capacity under our revolving credit facility. As of December 31, 2025, the available borrowings under our credit facility were reduced by $10.1 million due to outstanding letters of credit. As of December 31, 2024, we had $198.0 million of cash and cash equivalents and $188.7 million of additional borrowing capacity under our revolving credit facility. As of December 31, 2024, the available borrowings under our credit facility were reduced by $11.3 million, due to outstanding letters of credit.

Our revolving credit facility is available to fund our working capital requirements, capital expenditures and other general corporate purposes. We believe this resource is adequate for expected short-term and long-term needs.

Cash Flows

The consolidated statements of cash flows for the years ended December 31, 2025, 2024, and 2023 have not been adjusted to separately disclose cash flows related to the discontinued operations. Refer to Item 8, Note 3, Discontinued Operations for further information.

Year Ended December 31, 2025 Compared with the Year Ended December 31, 2024

Net cash provided by operating activities in the year ended December 31, 2025, was $346.5 million compared to $293.5 million in the year ended December 31, 2024 due to higher net income and lower use of cash for accruals, partially offset by cash used for trade working capital.

Cash used for investing activities was $29.9 million in the year ended December 31, 2025 compared to $20.2 million in the year ended December 31, 2024. Investing activities in the year ended December 31, 2025, included $29.9 million of capital expenditures. Investing activities for the year ended December 31, 2024, included $21.8 million of capital expenditures, which were partially offset by the receipt of $1.6 million from the sale of certain long-lived assets.

Cash used for financing activities was $217.3 million in the year ended December 31, 2025 compared to $207.5 million in the year ended December 31, 2024. Financing activities in the year ended December 31, 2025 included $63.9 million of cash for the payment of dividends on our common stock, $159.9 million of cash for repurchases of our common stock, $0.8 million of net cash payments on outstanding debt, and $0.6 million of cash used for the payment of withholding taxes on employees' share-based payment awards, which were offset by $7.9 million of net cash proceeds associated with stock option exercises and Employee Stock Purchase Plan ("ESPP") contributions. Financing activities in the year ended December 31, 2024 included $56.6 million of cash for the payment of dividends on our common stock, $150.2 million of cash for repurchases of our common stock, $0.8 million of net cash payments on outstanding debt, and $8.6 million of cash used for the payment of withholding taxes on employees' share-based payment awards, which were offset by $8.7 million of net cash proceeds associated with stock option exercises and ESPP contributions.

Indebtedness

As of December 31, 2025 we had $496.5 million of total indebtedness outstanding as follows (in millions):

____________________

(1)Includes unamortized original issue discount and debt issuance costs of $4.0 million at December 31, 2025.

See Item 8, Note 10, Long-Term Debt for a description of our outstanding indebtedness.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet or non-consolidated special-purpose entities.

Contractual Obligations

Our primary material cash requirements include the payment of interest and principal on our outstanding term loans and finance lease obligations, purchase commitments, operating lease obligations, and pension and other post-retirement plans.

The timing of principal payments associated with our term loan and finance lease obligations are disclosed in Item 8, Note 10, Long-Term Debt. We pay interest monthly based on prevailing interest rates at the time and the balance outstanding on our term loans and finance lease obligations.

Our operating lease obligations are primarily for real estate leases and automobile leases. See Item 8, Note 12, Leases for future minimum lease payments associated with our lease portfolio.

We have long-term obligations related to our deferred compensation, pension and other post-retirement plans that are summarized in Item 8, Note 14, Retirement Benefits.

As part of our global sourcing strategy, we have entered into agreements with key suppliers that require the supplier to maintain minimum levels of inventory to support certain products for which we require a short lead time to fulfill customer demand. We have the ability to notify the supplier that they no longer need to maintain the minimum level of inventory should we discontinue manufacturing a product during the contract period; however, we must purchase the remaining minimum inventory levels the supplier was required to maintain within a defined period of time.

We believe our cash flows from operations and existing borrowing capacity should be sufficient to satisfy our material cash requirements over the short-term and the long-term.

Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk during the normal course of business from changes in foreign currency exchange rates and interest rates. The exposure to these risks is managed through a combination of normal operating and financing activities and at times derivative financial instruments in the form of foreign currency forward contracts to cover certain known foreign currency transactional risks. We also have historically entered into interest rate derivatives to manage interest rate fluctuations.

Foreign Currency Exchange Rate Risk

Our exposure to foreign currency exchange rates relates primarily to our operations in Canada. For our operations in Canada, exchange rates impact the U.S. Dollar ("USD") value of our reported earnings, our investments in the subsidiaries and the intercompany transactions with the subsidiaries.

Approximately 10% of our sales originated outside of the United States in the year ended December 31, 2025. Revenues and expenses denominated in foreign currencies are translated into USD at the end of the fiscal period using the average exchange rates in effect during the period. Fluctuations in currency exchange rates also impact the USD amount of our stockholders' equity. The assets and liabilities of our non-U.S. subsidiaries are translated into USD at the exchange rates in effect at the end of the fiscal periods. As of December 31, 2025, stockholders' equity increased by $4.9 million from December 31, 2024 as a result of foreign currency translation adjustments. If the USD strengthened by 10% as of December 31, 2025, the result would have decreased stockholders' equity by approximately $13.1 million.

As of December 31, 2025, we had not entered into foreign currency forward contracts.

Interest Rate Risk

Our indebtedness under the senior secured credit facilities bears interest at rates that fluctuate with changes in certain short-term prevailing interest rates. As of December 31, 2025, our outstanding borrowings under the term loan facility were $476.4 million (net of $4.0 million unamortized debt issuance costs) and bore a weighted-average effective interest rate of 5.80%, determined as Term SOFR (subject to a 0.5% floor), plus a Term SOFR adjustment of 0.115%, plus an applicable margin of 2.00%. During the year ended December 31, 2025, the weighted-average interest rate was 6.36%.

Our net income is affected by changes in market interest rates on our variable-rate obligations. As discussed above, our term loan facilities bear interest at Term SOFR (subject to a 0.5% floor), plus a Term SOFR adjustment plus an applicable margin. Therefore, a 100 basis point increase in Term SOFR above where it closed as of December 31, 2025 would increase the annual interest expense under our term loan facility by approximately $4.9 million.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Zurn Elkay Water Solutions Corporation

Opinion on Internal Control Over Financial Reporting

We have audited Zurn Elkay Water Solutions Corporation and subsidiaries’ internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Zurn Elkay Water Solutions Corporation and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and December 31, 2024, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) and our report dated February 9, 2026 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

December 31, 2025

1. Basis of Presentation and Description of Business

The consolidated financial statements included herein have been prepared by Zurn Elkay Water Solutions Corporation ("Zurn Elkay" or the "Company"), in accordance with accounting principles generally accepted in the United States ("GAAP") pursuant to the rules and regulations of the Securities and Exchange Commission. The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, the consolidated financial statements include all adjustments necessary for a fair presentation of the financial position and the results of operations for the periods presented.

U.S. Pension Plan Termination & Settlement

Divestiture of Asbestos Liabilities and Certain Assets

Spin-Off of Process & Motion Control Segment

On October 4, 2021, the Company completed a Reverse Morris Trust tax-free spin-off transaction (the “Spin-Off Transaction”). Following completion of the Spin-Off Transaction, the Company's name was changed to “Zurn Water Solutions Corporation” and was subsequently changed to "Zurn Elkay Water Solutions Corporation".

As a result of the Spin-Off Transaction, in accordance with the authoritative guidance, the operating results of PMC are reported as discontinued operations in the consolidated statements of operations for all periods presented. The consolidated statements of cash flows for the years ended December 31, 2025, 2024, and 2023 have not been adjusted to separately disclose cash flows related to the discontinued operations. See Note 3, Discontinued Operations for additional information.

The Company

Zurn Elkay is a growth-oriented, pure-play water management business that designs, procures, manufactures, and markets what the Company believes to be the broadest sustainable product portfolio of specification-driven water management solutions to improve health, hydration, human safety and the environment. The Company's product portfolio includes professional grade water safety and control products, flow systems products, hygienic and environmental products, and filtered drinking water products for public and private spaces that deliver superior value to building owners, positively impact the environment and human hygiene and reduce product installation time. The Company's heritage of innovation and specification has allowed it to provide highly-engineered, mission-critical solutions to customers for decades and affords it the privilege of having long-term, valued relationships with market leaders. The Company operates in a disciplined way and the Zurn Elkay Business System (“ZEBS”) is its operating philosophy. Grounded in the spirit of continuous improvement, ZEBS creates a scalable, process-based framework that focuses on driving superior customer satisfaction and financial results by targeting world-class operating performance throughout all aspects of its business.

2. Significant Accounting Policies

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue Recognition

See Note 5, Revenue Recognition for the Company's policy for recognizing revenue under Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers ("ASC 606") as well as the various other disclosures required by ASC 606.

Leases

The Company determines if an arrangement is a lease, or contains a lease, at the inception of the arrangement and determines whether it is an operating or financing lease. Operating and financing leases result in the Company recording a right-of-use ("ROU") asset, current lease liability, and long-term lease liability on its balance sheet. Lease expense for operating leases and amortization expense for finance leases is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet and are instead recognized on a straight-line basis over the lease term. See Note 12, Leases, for additional discussion about the Company's policy for accounting for leases and other required disclosures.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718, Accounting for Stock Compensation ("ASC 718"). ASC 718 requires compensation costs related to stock-based payment transactions to be recognized in the financial statements. Generally, compensation cost is measured based on the grant-date fair value of the equity instruments issued. Compensation cost is recognized over the requisite service period, generally as the awards vest. See further discussion of the Company’s equity plans in Note 13, Stock-Based Compensation.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less to be cash and cash equivalents. Cash and cash equivalents that are restricted from operating use are classified as restricted cash. We had $40.1 million and $38.8 million classified as restricted cash as of December 31, 2025 and 2024, respectively.

Receivables

Receivables are stated net of allowances for credit losses of $1.2 million at December 31, 2025, and $1.8 million at December 31, 2024. The Company assesses the collectability of customer receivables based on the credit worthiness of a customer as determined by credit checks and analysis, as well as the customer’s payment history. In determining the allowance for credit losses, the Company also considers various factors including the aging of customer accounts and historical write-offs. In addition, the Company monitors other risk factors, including forward-looking information when establishing adequate allowances for credit losses, which reflects the current estimate of credit losses expected to be incurred over the life of the receivables. Generally, advance payment is not required. Allowances for credit losses established are recorded within selling, general and administrative expenses within the consolidated statements of operations.

Inventories

Inventories are comprised of material, direct labor and manufacturing overhead, and are stated at the lower of cost or market. Market is determined based on estimated net realizable values. The percentage of the Company’s total inventories valued using the Last-In, First-Out ("LIFO") method was 89% and 94% at December 31, 2025 and 2024, respectively. All remaining inventories are valued using the First-In, First-Out ("FIFO") method.

In some cases, the Company has determined a certain portion of inventories are excess or obsolete. In those cases, the Company writes down the value of those inventories to their net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, adjustments to established inventory reserves may be required. The total write-down of inventories charged to expense was $2.2 million, $11.6 million and $3.4 million, during the years ended December 31, 2025, 2024, and 2023, respectively.

Property, Plant and Equipment

Property, plant and equipment are initially stated at cost. Depreciation is provided using the straight-line method over 10 to 30 years for buildings and improvements, 5 to 10 years for machinery and equipment and 3 to 5 years for computer hardware and software. Where appropriate, the depreciable lives of certain assets may be adjusted to reflect a change in the use of those assets, or depreciation may be accelerated in the case of an eventual asset disposal.

Goodwill and Intangible Assets

Intangible assets consist of acquired trademarks and tradenames, customer relationships (including distribution network) and patents. The customer relationships, patents, and certain tradenames are being amortized using the straight-line method over their estimated useful lives of 7 to 20 years, 3 to 13 years and 5 to 20 years, respectively. Where appropriate, the lives of certain intangible assets may be adjusted to reflect a change in the use of those assets, or amortization may be accelerated in the case of a known intangible asset discontinuation.

Goodwill, trademarks and certain tradenames have indefinite lives and are not amortized. However, the goodwill and intangible assets are tested annually for impairment, and may be tested more frequently if any triggering events occur that would reduce the recoverability of the asset. In conducting the annual impairment test for goodwill, the Company has the option to first assess qualitative factors to determine whether it is more likely than not (greater than 50% likelihood) the fair value of any reporting unit is less than its carrying amount. If a qualitative assessment determines an impairment is more likely than not, the Company is required to perform a quantitative impairment test. Otherwise, no further analysis is required. Alternatively, the Company may elect to proceed directly to the quantitative impairment test. In conducting a quantitative assessment, the Company utilizes a discounted cash flow methodology based on future business projections and a market value approach (guideline public company comparables). The Company performs the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. If the carrying amount exceeds the fair value of the reporting unit, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value up to the amount of the recorded goodwill.

During the fourth quarter of the year ended December 31, 2025, the Company completed its annual goodwill and intangible asset impairment tests and elected to perform a qualitative assessment.No goodwill impairment charges were recorded during the years ended December 31, 2025, 2024, or 2023. During the year ended December 31, 2024, we recorded a $0.6 million impairment charge related to an indefinite-lived tradename no longer used. No intangible asset impairment charges were recorded during the years ended December 31, 2025 or 2023.

Impairment of Long-Lived Assets

The carrying value of long-lived assets, including amortizable intangible assets and tangible fixed assets, are evaluated for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Impairment of amortizable intangible assets and tangible fixed assets is generally determined by comparing projected undiscounted cash flows to be generated by the asset, or group of assets, to its carrying value. If impairment is identified, a loss is recorded equal to the excess of the asset's net book value over its fair value, and the cost basis is adjusted accordingly. During the years ended December 31, 2025, 2024, and 2023, the Company recognized $2.0 million, $7.4 million, and $2.5 million of fixed asset impairment charges, respectively. Impairments are determined utilizing Level 3 inputs within the Fair Value hierarchy, and the Company reviews and considers input from outside specialists, when appropriate. Actual results could vary from these estimates. Refer to Note 11, Fair Value Measurements for additional information.

Product Warranty

The Company offers warranties on the sales of certain of its products and records an accrual for estimated future claims. Such accruals are based upon historical experience and management’s estimate of the level of future claims.The following table presents changes in the Company’s product warranty liability during each of the periods presented (in millions):

Year Ended

Balance at beginning of period $ 4.9 $ 4.7 $ 4.2

Charged to operations 4.1 3.0 2.4

Claims settled (2.4) (2.8) (1.9)

Less current reserve $ 3.1 $ 4.9 $ 4.7

Long-term reserve $ 3.5 $ — $ —

Income Taxes

Deferred income taxes are provided for future tax effects attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, net operating losses, tax credits and other applicable carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be actually paid or recovered. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of continuing operations in the period that includes the date of enactment.

The Company regularly reviews its deferred tax assets for recoverability and provides a valuation allowance against its deferred tax assets if, based upon consideration of all positive and negative evidence, the Company determines that it is more-likely-than-not that a portion or all of the deferred tax assets will ultimately not be realized in future tax periods. Such positive and negative evidence would include review of historical earnings and losses, anticipated future earnings, the time period over which the temporary differences and carryforwards are anticipated to reverse and implementation of feasible, prudent tax planning strategies.

The Company is subject to income taxes in the United States and multiple foreign jurisdictions. Significant judgment is required in determining the Company’s worldwide provision for income taxes and recording the related deferred tax assets and liabilities. In the ordinary course of the Company’s business, there is inherent uncertainty in quantifying the ultimate tax outcome of all the numerous transactions and required calculations relating to the Company’s tax positions. Accruals for unrecognized tax benefits are provided for in accordance with the requirements of ASC 740, Income Taxes ("ASC 740"). An unrecognized tax benefit represents the difference between the recognition of benefits related to uncertain tax positions for income tax reporting purposes and financial reporting purposes. The Company has established a reserve for interest and penalties, as applicable, for uncertain tax positions and it is recorded as a component of the overall income tax provision.

The Company is subject to periodic income tax examinations by domestic and foreign income tax authorities. Although the outcome of income tax examinations is always uncertain, the Company believes that it has appropriate support for the positions taken on its income tax returns and has adequately provided for potential income tax assessments. Nonetheless, the amounts ultimately settled relating to issues raised by the taxing authorities may differ materially from the amounts accrued for each year.

See Note 15, Income Taxes for additional information.

Per Share Data

Basic net income per share from continuing and discontinued operations is computed by dividing net income from continuing operations and income from discontinued operations, respectively, by the corresponding weighted average number of common shares outstanding for the period. Diluted net income per share from continuing and discontinued operations is computed based on the weighted average number of common shares outstanding, increased by the number of incremental shares that would have been outstanding if the potential dilutive shares were issued through the exercise of outstanding stock options to purchase common shares and the vesting of restricted stock units and performance stock units using the treasury stock method, except when the effect would be anti-dilutive.

There were no common shares with anti-dilutive effects for the year ended December 31, 2025. The computation for diluted net income per share for the years ended December 31, 2024 and 2023 excludes 0.2 million and 0.3 million common shares due to their anti-dilutive effects, respectively.

Accumulated Other Comprehensive Loss

The changes in accumulated other comprehensive loss, net of tax, for the years ended December 31, 2025, 2024, and 2023 are as follows (in millions):

Other comprehensive income before reclassifications $ 3.6 $ 3.7 $ 7.3

Other comprehensive income before reclassifications $ 4.9 $ 0.8 $ 5.7

Amounts reclassified from accumulated other comprehensive loss — (8.0) (8.0)

Net current period other comprehensive income (loss) 4.9 (7.2) (2.3)

The following table summarizes the amounts reclassified from accumulated other comprehensive loss to net income for the year ended December 31, 2025 (in millions):

Year Ended

December 31, 2025 Income Statement Line

Pension and other postretirement benefit obligations

Settlement gain (10.0) Other income (expense), net

Provision for income taxes 2.0

Total net of tax $ (8.0)

There were no amounts reclassified from accumulated other comprehensive loss to net income during the years ended December 31, 2024 and 2023.

Foreign Currency Translation

Assets and liabilities of subsidiaries operating outside of the United States with a functional currency other than the U.S. dollar are translated into U.S. dollars using exchange rates at the end of the respective period. Revenues and expenses of such entities are translated at average exchange rates in effect during the respective period. Foreign currency translation adjustments are included as a component of accumulated other comprehensive loss. Currency transaction (gains) losses totaled $0.7 million, $(0.8) million and $0.9 million for the years ended December 31, 2025, 2024, and 2023, respectively, and are included in other income (expense), net in the consolidated statements of operations.

Advertising Costs

Advertising costs are charged to selling, general and administrative expenses on the consolidated statements of operations as incurred and amounted to $20.8 million, $18.1 million and $18.4 million for the years ended December 31, 2025, 2024, and 2023, respectively.

Research, Development and Engineering Costs

Research, development and engineering costs are charged to selling, general and administrative expenses on the consolidated statements of operations as incurred and amounted to $25.0 million, $25.9 million and $23.7 million for the years ended December 31, 2025, 2024, and 2023, respectively.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and temporary investments and trade accounts receivable.

Recent Accounting Pronouncements

In December 2023, the FASB issued Accounting Standards Update 2023-09 “Income Taxes (Topic 470): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which establishes new income tax disclosures to consistently categorize and provide greater disaggregation of information in the rate reconciliation, including dollar value and percentage impacts of each component of the reconciliation, as well as further disaggregates income taxes paid. This update is effective for the Company for annual fiscal periods beginning after December 15, 2024. The Company has adopted ASU 2023-09 for the

2025 calendar year prospectively. Because the ASU affects disclosures only, the adoption did not affect the Company’s consolidated statements of operations or consolidated balance sheets.

In November 2024, the FASB issued Accounting Standards Update 2024-03 “Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which is intended to improve disclosures about a public business entity's expenses, primarily through additional disaggregation of income statement expenses. The ASU’s amendments are effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The Company is evaluating the impact of the adoption of ASU 2024-03 on the consolidated financial statements.

In September 2025, the FASB issued Accounting Standards Update 2025-06 “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” ("ASU 2025-06"), which replaces the stage-based capitalization model for the treatment of development costs of internal-use software with a principles-based framework, reflecting modern software development practices. In addition, ASU 2025-06 requires companies to capitalize software costs once management authorizes and commits to funding with probable completion and use. This guidance will be effective for annual reporting periods beginning after December 15, 2027, and for interim periods within annual reporting periods within those annual reporting periods, and allows multiple transition methods, including retrospective, prospective, or modified prospective application, with early adoption permitted. The Company is evaluating the impact of the adoption of ASU 2025-06 on the consolidated financial statements.
