Gorman Rupp Co: Form 10-K for the period ended Dec 31, 2025

The Gorman-Rupp Company (“Registrant”, “Gorman-Rupp”, the “Company”, “we” or “our”) was incorporated in Ohio in 1934. The Company designs, manufactures and globally sells pumps and pump systems for use in water, wastewater, construction, dewatering, industrial, petroleum, original equipment, agriculture, fire suppression, heating, ventilating and air conditioning (“HVAC”), military and other liquid-handling applications.

PRODUCTS

The Company operates in one business segment, the manufacture and sale of pumps and pump systems. The following table sets forth, for the years 2023 through 2025, the total net sales, income before income taxes and year-end total assets of the Company.

(Dollars in thousands)

The Company’s product line consists of pump models ranging in size from 1/4” to nearly 15 feet and ranging in rated capacity from less than one gallon per minute to nearly one million gallons per minute. The types of pumps which the Company produces include self-priming centrifugal, standard centrifugal, magnetic drive centrifugal, axial and mixed-flow, vertical turbine line shaft, submersible, high-pressure booster, rotary gear, rotary vein, diaphragm, bellows and oscillating.

The pumps have drives that range from fractional horsepower electric motors up to much larger electric motors or internal combustion engines capable of producing several thousand horsepower. Many of the larger units comprise encased, fully-integrated water and wastewater pumping stations. In certain cases, units are designed for the inclusion of customer-supplied drives.

The Company’s larger pumps are sold principally for use in the construction, industrial, water and wastewater handling fields; for flood control; for boosting low residential water pressure; for pumping refined petroleum products, including the ground refueling of aircraft; for fluid control in HVAC applications; and for various agricultural purposes.

The Company’s pumps are also utilized for dewatering purposes. Additionally, pumps manufactured for fire suppression are used for sprinkler back-up systems, stand pipes, fog systems and deluge systems at hotels, banks, factories, airports, schools, public buildings, data centers, and hundreds of other types of facilities throughout the world.

Many of the Company’s smallest pumps are sold to customers for incorporation into such products as food processing, chemical processing, medical applications, computer cooling, waste treatment, HVAC equipment, appliances and solar heating.

MARKETING

The Company’s pumps are marketed in the United States and internationally through a broad network of distributors, through manufacturers’ representatives (for sales to certain original equipment manufacturers), through third-party distributor catalogs, direct sales, retailers, and e-commerce. The Company regularly seeks alliances with distributors and other partners to further enhance marketing opportunities. Export sales are made primarily through foreign distributors and representatives. The Company has long-standing relationships with many of the leading independent distributors in the markets it serves and provides specialized training programs to distributors on a regular basis.

During 2025, 2024 and 2023, there were no shipments to any foreign country nor to any single customer that exceeded 10% of total net sales. Gorman-Rupp continued to actively pursue international business opportunities and, in 2025, shipped its pumps to approximately 140 countries around the world.

COMPETITION

The pump industry is highly fragmented and therefore Gorman-Rupp competes with a large number of businesses. Numerous pump competitors exist as subsidiaries, divisions or departments within significantly larger corporations. The Company also faces increased competition from foreign-sourced pumps in most of the Company’s domestic markets.

Most commercial and industrial pumps are specifically designed and engineered for a particular customer’s application. The Company believes that proper application, product performance, and quality of delivery and service are its principal methods of competition, and attributes its success to its continued emphasis in these areas. In the sale of products and services, the Company benefits from its large base of previously installed products, which periodically require replacement parts due to the critical application and nature of the products and the conditions under which they operate.

PURCHASING AND PRODUCTION

Substantially all of the materials, supplies, components and accessories used by the Company in the fabrication of its products, including all castings (for which most patterns are made and owned by the Company), structural steel, bar stock, motors, solenoids, engines, seals, and plastic and elastomeric components are purchased by the Company from other suppliers and manufacturers. The Company purchases motor components for its large submersible pumps, and motors and engines for its pump systems, from a limited number of suppliers. The Company does not purchase materials under long-term contracts and is not dependent upon a single source for any materials, supplies, components or accessories which are of material importance to its business.

The other production operations of the Company consist of the machining of castings, the cutting, shaping and welding of bar stock and structural members, the design and assembly of electrical control panels, the manufacture of some small motors and a few minor components, and the assembling, painting and testing of its products. The majority of the Company’s products are tested prior to shipment.

HUMAN CAPITAL

As of December 31, 2025, the Company employed approximately 1,415 persons, of whom approximately 740 were hourly employees. The majority of the Company’s manufacturing operations take place in the United States, as evidenced by 87% of its employees being in the Company’s U.S. locations and 13% of its employees being in its international locations.

Our approach is to develop talent from within and supplement with external hires. We invest resources to develop the talent needed to remain a leading designer and manufacturer of pumps and pump systems. We provide our employees with training opportunities and educational benefits to assist in the expansion of their careers and skills. This approach has resulted in a deep understanding among our employee base of our business, products, and customers. We believe that our average tenure of 12 years, as of the end of 2025, reflects both the strong engagement of our employees and our positive workplace culture. Approximately 7% of our employees operate under a collective bargaining agreement, which expires within the next twelve months. The Company has never experienced a work stoppage.

We provide competitive compensation and benefits programs to help meet the needs of our employees. In addition to salaries, these programs (which vary by country and region) include profit sharing, a 401(k) plan, medical insurance and benefits, health savings accounts, paid time off, and tuition assistance, among others. Certain domestic employees hired prior to January 1, 2008, participate in a defined benefit plan. Employees hired after this date, in eligible locations, participate in an enhanced 401(k) plan instead of the defined benefit plan. To create performance incentives and to encourage employees to voluntarily invest in the Company’s Common Shares, we have made the purchase of common shares convenient, in some cases with partial cash matching contributions from the Company, and in all cases without brokers’ fees or commissions, under an Employee Stock Purchase Plan, a 401(k) Plan and a Dividend Reinvestment Plan. Because our business involves the manufacturing of products, many of our employees are unable to work from home. For certain positions, we do provide hybrid work from home options.

The health and safety of our workforce is fundamental to the success of our business. We provide our employees upfront and ongoing safety training to ensure that safety policies and procedures are effectively communicated and implemented. We also provide personal protective equipment to those employees who need it to perform their job functions safely. We have experienced personnel on-site at each of our manufacturing locations who are tasked with environmental, health and personal safety education and compliance.

We are committed to upholding fundamental human rights and believe that all human beings should be treated with dignity, fairness and respect. This commitment is outlined in our Human Rights Policy which applies to all employees worldwide including part time and temporary workers. We communicate our expectation that suppliers also adhere to our Human Rights Policy through our Supplier Code of Conduct. We strive to promote opportunities in the workplace, engage with our communities, and encourage our suppliers to treat their employees in a manner that respects human rights. We utilize an on-line platform to provide training to all employees worldwide in key areas such as harassment and discrimination prevention, human rights, and our code of conduct. We also internally publicize the availability of an anonymous ethics hotline through which any employee may report any ethics, safety or other employment concerns.

OTHER ASPECTS

Although the Company owns a number of patents, several of which are important to its business, the Company does not consider its business to be materially dependent upon any one or more patents. The Company’s patents, trademarks and other intellectual property are adequate for its business purposes.

Gorman-Rupp makes available free of charge on or through www.gormanrupp.com (http://www.gormanrupp.com) its Annual Report to Shareholders, its annual Proxy Statement, its annual report on Form 10-K, its quarterly reports on Form 10-Q, and its current reports on Form 8-K, and any amendments to those reports, as soon as reasonably practicable after those reports (and any amendments) are electronically filed with or furnished to the Securities and Exchange Commission (“Commission”). However, the information contained on the Company’s website is not a part of this Form 10-K or any other report filed with or furnished to the Commission.

A paper copy of the Company’s Form 10-K is also available free of charge upon written request to the Company’s Corporate Secretary.

Gorman-Rupp’s business and financial performance are subject to various risks and uncertainties, some of which are beyond its control. In addition to the risks discussed elsewhere in this Form 10-K, the following risks and uncertainties could materially adversely affect the Company’s business, prospects, financial condition, results of operations, liquidity and access to capital markets. These risks could cause the Company’s actual results to differ materially from its historical experience and from expected results discussed in forward-looking statements made by the Company related to conditions or events that it anticipates may occur in the future.

COMPANY SPECIFIC RISK FACTORS

Loss of key personnel

The Company’s success depends to a significant extent on the continued service of its executive management team and the ability to recruit, hire and retain other key management personnel to support the Company’s growth and operational initiatives and replace executives who retire or resign. Failure to retain key management personnel and attract and retain other highly-skilled personnel could limit the Company’s global growth and ability to execute operational initiatives, or may result in inefficient and ineffective management and operations, which could harm the Company’s revenues, operations and product development efforts and could eventually result in a decrease in profitability.

Intellectual property security

The Company possesses a wide array of intellectual property rights, including patents, trademarks, copyrights, and applications for the above, as well as other proprietary information. There is a risk that third parties would attempt to copy, in full or in part, the Company’s products, technologies or industrial designs, or to obtain unauthorized access and use of Company technological know-how or other protected intellectual property rights. Also, other companies could successfully develop technologies, products or industrial designs similar to the Company’s, and thus potentially compete with the Company. From time to time, the Company has been faced with instances where competitors have infringed or unfairly used its intellectual property or taken advantage of its design and development efforts. The ability to protect and enforce intellectual property rights varies across jurisdictions. Competitors have attempted, and may in the future attempt to copy the Company’s products, technologies or industrial designs. If the Company is unable to adequately enforce and protect its intellectual property rights, it could adversely affect its revenues and profits and hamper its ability to grow.

Competitors and others may also challenge the validity of the Company’s intellectual property or allege that it has infringed their intellectual property, including through litigation. The Company may be required to pay substantial damages if it is determined its products infringe the intellectual property of others. The Company may also be required to develop an alternative, non-infringing product that could be costly and time-consuming, or acquire a license (if available) on terms that are not favorable to it. Regardless of whether infringement claims against the Company are successful, defending against such claims could significantly increase the Company’s costs, divert management’s time and attention away from other business matters, and otherwise adversely affect the Company’s results of operations and financial condition.

Growth through acquisitions

The Company’s historical growth has depended, and its future growth is likely to continue to depend, in part on its acquisition strategy and the successful integration of acquired businesses into existing operations. The Company intends to continue to seek additional domestic and international acquisition opportunities that have the potential to support and strengthen its operations. The Company cannot assure it will be able to successfully identify suitable acquisition opportunities, prevail against competing potential acquirers, negotiate appropriate acquisition terms, obtain financing that may be needed to consummate such acquisitions, complete proposed acquisitions, successfully integrate acquired businesses into existing operations or expand into new markets. In addition, the Company cannot assure that any acquisition, even if successfully integrated, will perform as planned, be accretive to earnings, or prove to be beneficial to the Company’s operations and cash flows. Additional potential risks associated with acquisitions are the diversion of management's attention from other business concerns, additional debt leverage, the loss of key employees and customers of the acquired business, the assumption of unknown liabilities, disputes with sellers, and the inherent risk associated with the Company entering new lines of business.

The Company has substantial indebtedness, which may impact the Company’s financial condition and the way it operates its business

The Company has substantial indebtedness. Such indebtedness includes senior secured first lien credit facilities comprised of a $370 million term loan facility and a $100 million revolving credit facility, and $30 million in aggregate principal amount of 6.40% senior secured notes. The indebtedness could have important negative consequences, including:

• higher borrowing costs resulting from fluctuations in our variable benchmark borrowing rates that have adversely affected, and could in the future adversely affect, our interest rates;
• reduced availability of cash for the Company’s operations and other business activities after satisfying interest payments and other requirements under the terms of its debt instruments;
• less flexibility to plan for or react to competitive challenges, and a competitive disadvantage relative to competitors that do not have as much indebtedness;
• limiting the Company’s ability to undertake mergers or dispositions of assets, or pay dividends;
• difficulty in obtaining additional financing in the future;
• inability to comply with covenants in, and potential for default under, the Company’s debt instruments;
• inability to operate our business or to take advantage of business opportunities due to restrictions created from the debt covenants; and
• challenges to repaying or refinancing any of the Company’s debt.

The Company’s ability to satisfy its debt and other obligations will depend principally upon its future operating performance. As a result, prevailing economic conditions and financial, business, legal and regulatory and other factors, many of which are beyond the Company’s control, may affect its ability to make payments on its debt and other obligations.

Impairment in the value of intangible assets, including goodwill

The Company’s total assets reflect goodwill from acquisitions, representing the excess cost over the fair value of the identifiable net assets acquired, including other indefinite-lived and finite-lived intangible assets. Goodwill and other indefinite-lived intangible assets are not amortized but are reviewed annually for impairment as of October 1 or whenever events or changes in circumstances indicate there may be a possible permanent loss of value using either a quantitative or qualitative analysis. Finite-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recovered through future net cash flows generated by the assets. If future operating performance at one or more of the Company’s reporting units were to fall significantly below forecast levels or if market conditions for one or more of its acquired businesses were to decline, the Company could be required to incur a non-cash charge to operating income for impairment. Any impairment in the value of these assets could have an adverse non-cash impact on the Company’s reported results of operations.

Defined benefit pension plan settlement expense

The Company sponsors a defined benefit pension plan (“GR Plan”) covering certain domestic employees and accrues amounts for funding of its obligations under the plan. The GR Plan allows eligible retiring employees to receive a lump-sum distribution for benefits earned in lieu of annual payments and most of the Company’s eligible retirees historically have elected this option. Under applicable accounting rules, if the lump-sum distributions made for a plan year exceed an actuarially-determined threshold of the total of the service cost and interest cost for the plan year, the Company at such point would be required to recognize for that year’s results of operations settlement expense for the resulting unrecognized actuarial loss. The Company has been required to make such adjustments in prior periods, and, if such non-cash adjustments are necessary in future periods, they may negatively impact the Company’s operating results.

In 2025, the Company recorded pre-tax non-cash pension settlement charges of $1.2 million, driven by lump-sum distributions discussed above. There was no pension settlement charge recorded in 2024 or 2023. See Note 8 to the Consolidated Financial Statements, Pensions and Other Postretirement Benefits.

LIFO inventory method

The majority of the Company’s inventories are valued on the last-in, first-out (LIFO) method and stated at the lower of cost or market. Current cost approximates replacement cost, or market, and LIFO cost is determined at the end of each fiscal year based on inventory levels on-hand at current replacement cost and a LIFO reserve. The Company uses the simplified LIFO method, under which the LIFO reserve is determined utilizing the inflation factor specified in the Producer Price Index for Machinery and Equipment – Pumps, Compressors and Equipment, as published by the U.S. Bureau of Labor Statistics. Interim LIFO calculations are based on management’s estimate of the expected year-end inflation index and, as such, are subject to adjustment each quarter including the fourth quarter when the inflation index for the year is finalized. If inflation causes the Producer Price Index for Machinery and Equipment – Pumps, Compressors and Equipment to increase in future periods, the LIFO reserve will increase with a corresponding increase to non-cash LIFO expense which may negatively impact the Company’s operating results.

In 2025, 2024, and 2023, the Company recorded pre-tax non-cash LIFO expense of $4.4 million, $5.1 million, and $6.9 million, respectively. See Note 3 to the Consolidated Financial Statements, Inventories.

As of December 31, 2025 the Company had a LIFO reserve of $104.6 million, which at the current U.S. Corporate tax rate, represents approximately $22.0 million of income taxes, payment of which is delayed to future dates based upon changes in inventory costs. From time-to-time, discussions regarding changes in U.S. tax laws have included the potential of LIFO being repealed. Should LIFO be repealed, the $22.0 million of postponed taxes, plus any future benefit realized prior to the date of repeal, would likely have to be repaid over some period of time. Repayment of these postponed taxes will reduce the amount of cash that we would have available to fund our operations, working capital, capital expenditures, acquisitions, or general corporate or other business activities. This could materially and adversely affect our business, financial condition and results of operations.

Family ownership of common equity

A substantial percentage of the Company’s common shares is held by various members of the Gorman family and their respective affiliates. Because of this concentrated ownership relative to many other publicly-traded companies, the market price of the Company’s common shares may be influenced by lower trading volume and therefore more susceptible to price fluctuations than many other companies’ shares. If any one or more of the Company’s significant shareholders were to sell all or a portion of their holdings of Company common shares at once or within short periods of time, or there was an expectation that such a sale was imminent, then the market price of the Company’s common shares could be negatively affected.

GENERAL RISK FACTORS

Continuation of current and projected future business environment

The overall pump industry is cyclical in nature, and some of its business activity is related to general business conditions in the durable goods and capital equipment markets. Demand for most of the Company’s products and services is affected by the level of new capital investment and planned maintenance expenditures by its customers. The level of such investment and expenditures by our customers depends, in turn, on factors such as general economic conditions, availability of credit, economic conditions within their respective industries and expectations of future market behavior. Volatility or sustained increases in prices of commodities such as oil and agricultural products can negatively affect the levels of investment and expenditures of certain customers and result in postponement of capital investment decisions or the delay or cancellation of existing orders. Inflationary economic conditions may further increase prices and exacerbate these risks. Any of these developments may negatively impact the Company’s sales.

The effects of executive actions and executive orders by the President in connection with, among other areas, energy production, trade, immigration and administrative agencies, as well as any tandem regulatory changes pursued by the current administration, are highly uncertain and may adversely impact our business.

Highly competitive markets

Gorman-Rupp sells its products in highly competitive markets. Maintaining and improving the Company’s competitive position requires periodic investment in manufacturing, engineering, quality standards, marketing, customer service and support, and distribution networks. Even with such investment, the Company may not be successful in maintaining its competitive position. The Company’s competitors may develop products that are superior to its products, or may develop methods of more efficiently and effectively providing products and services, or may adapt more quickly to new technologies or evolving customer requirements. Pricing pressures may require the Company to adjust the prices of its products downward to stay competitive. The Company may not be able to compete successfully with its existing competitors or with new competitors. Failure to compete successfully could negatively impact the Company’s sales, operating margins and overall financial performance.

Availability and costs of raw materials and labor

The Company could be adversely affected by raw material price volatility or an inability of its suppliers to meet quality and delivery requirements. We are required to maintain sufficient inventories to accommodate the needs of our customers, often with short lead times. Our business could be adversely affected if we fail to source and maintain adequate inventory levels. Raw material and energy expenses are substantial drivers of costs in the manufacture of pumps and changes in these costs are often unpredictable. While the Company manufactures certain parts and components used in its products, the Company’s business requires substantial amounts of raw materials, parts and components to be purchased from suppliers. The availability and prices of raw materials, parts and components purchased from the Company’s suppliers may be subject to curtailment or change due to, among other things, suppliers’ allocations to other purchasers, interruptions or delays in production or deliveries by suppliers, changes in exchange rates, tariffs, changes in duty rates and changes in other trade barriers and import and export licensing requirements. The effects of international trade conflicts between the U.S. and its global trade partners including, without limitation, China, Mexico and Canada, may have an adverse impact on economic conditions, and commodity and raw materials pricing and availability.

The Company's business depends, in part, upon the adequate recruitment and retention, and continued service of, key managerial, engineering, marketing, sales and technical and operational personnel. Economic conditions may cause an increasingly competitive labor market, which could lead to labor shortages or increased turnover rates within, or increased labor costs to maintain, the Company’s employee base.

These considerations may also impact the operations of the Company’s suppliers, who may seek to pass along any increased costs to the Company. Inflationary economic conditions and tariffs may further increase these various costs. The Company may not be able to pass along any increased material or labor costs to customers for competitive or other reasons. A change in the availability of, or increases in the costs associated with raw materials, parts and components or labor and workforce could affect our ability to fulfill our customer backlog and materially affect our business, financial condition, results of operations or cash flows.

Cybersecurity threats

Increased global information technology security threats and more sophisticated and targeted computer crime pose a risk to the security of Gorman-Rupp’s systems and networks and to the confidentiality, availability, and integrity of its data. While the Company attempts to mitigate these risks by employing a number of measures, including employee training, comprehensive monitoring of its networks and systems, and the deployment of backup and protective systems, the Company’s systems, networks, proprietary information, products, solutions and services remain potentially vulnerable to advanced persistent threats. Depending on their nature and scope, such threats could potentially lead to liability for damages or the loss of confidential information including as a result of, but not limited to, the compromising of confidential information relating to customer, supplier, or employee data, improper use of the Company’s systems and networks, manipulation and destruction of data, defective products, production downtimes and operational disruptions which, in turn, could adversely affect Gorman-Rupp’s reputation, competitiveness and results of operations.

Artificial intelligence presents risks and challenges that can impact our business

Issues in the development and use of artificial intelligence, combined with an uncertain regulatory environment, may result in reputational harm, liability or other adverse consequences to our business operations. As with many technological innovations, artificial intelligence presents risks and challenges that could impact our business. We work with vendors that incorporate artificial intelligence tools into their offerings and the providers of these artificial intelligence tools may not meet existing or rapidly evolving regulatory or industry standards with respect to privacy and data protection and may inhibit our or our vendors’ ability to maintain an adequate level of service and experience. If we, our vendors, or our third-party partners experience an actual or perceived breach or privacy or security incident because of the use of generative artificial intelligence, we may lose valuable intellectual property and confidential information and our reputation and the public perception of the effectiveness of our security measures could be harmed. 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.

Compliance with, and costs related to, a variety of import and export laws and regulations

The Company is subject to a variety of laws and regulations regarding international operations, including regulations issued by the U.S. Department of Commerce Bureau of Industry and Security and various other domestic and foreign governmental agencies. Actual or alleged violations of import-export laws could result in enforcement actions and/or financial penalties. The Company cannot predict the nature, scope or effect of future regulatory requirements to which our international operations and trading practices might be subject or the manner in which existing laws or regulations might be administered or interpreted. Future legislation or regulations could limit the countries in which certain of our products may be manufactured or sold or could restrict our access to, and increase the cost of obtaining, products from foreign sources.

U.S. trade policy, including the implementation of tariffs, could adversely affect the Company’s business and financial results

The U.S. administration has implemented numerous tariffs on imported materials and products and, in response, various countries have imposed new, or increased existing, tariffs on imports. These tariffs, to the extent that they continue to be imposed, and any new or increased tariffs, may increase the cost of imported materials used by our suppliers and in our products. Tariffs imposed by other countries may apply to our products sold internationally. The ultimate impact of the announced tariffs and any future tariffs will depend on various factors, including the extent to which such tariffs are implemented, the timing of implementation and the amount, scope and nature of such tariffs. If we are unable to mitigate the impact of tariffs, including through product pricing and supply arrangements, our business and financial results could be adversely affected.

Environmental compliance costs and liabilities

The Company’s operations and properties are subject to numerous domestic and foreign environmental laws and regulations which can impose operating and/or financial sanctions for violations. Moreover, environmental and sustainability initiatives, practices, rules and regulations are under increasing scrutiny of both governmental and non-governmental bodies and may compel the Company to implement changes to its operational practices, standards and expectations and, in turn, increase the Company’s compliance costs. Periodically, the Company has incurred, and it expects to continue to incur, operating and capital costs to comply with environmental requirements. The Company monitors its environmental responsibilities, together with trends in the related laws, and believes it is in substantial compliance with current regulations. If the Company incurs increased compliance costs or violates environmental laws or regulations, future environmental compliance expenditures or liabilities could have a material adverse effect on our financial condition, results of operations or cash flows.

Exposure to fluctuations in foreign currency exchange rates

The Company is exposed to fluctuations in foreign currency exchange rates, particularly with respect to the Euro, Canadian Dollar, South African Rand and British Pound. Any significant change in the value of these currencies could affect the Company’s ability to sell products competitively and control its cost structure, which could have a material effect on its financial condition, results of operations or cash flows.

Conditions in foreign countries in which the Company conducts business

In 2025, 24% of the Company’s net sales were to customers outside the United States. The Company expects its international and export sales to continue to be a significant portion of its revenue. The Company’s sales from international operations and export sales, and the availability and prices of certain raw materials, parts, and components, are subject, in varying degrees, to risks inherent to doing business outside the United States. These risks include, but are not limited to, the following, some of which are further addressed in our other Risk Factors:

• Possibility of unfavorable circumstances arising from host country laws or regulations;
• Currency exchange rate fluctuations and restrictions on currency repatriation;
• Potential negative consequences from changes to taxation policies;
• Disruption of operations from labor or political disturbances, or public health crises;
• Changes in tariffs, duty rates, and other trade barriers and import and export licensing requirements;
• Increased costs and risks of developing, staffing and simultaneously managing a number of global operations as a result of distance as well as language and cultural differences; and
• Insurrections, armed conflicts, terrorism or war.

In particular, the effects on the global economy from international trade conflicts between the U.S. and its global trade partners including, without limitation, China, Mexico and Canada, and any escalation or broadening of armed conflicts in Ukraine and the Middle East, including attacks on shipping vessels in key shipping routes, are uncertain. Any of these events or those referenced above could have an adverse impact on the Company’s business and operations.

Changes in our tax rates and exposure to additional income tax liabilities

Gorman-Rupp is subject to income and other taxes in the United States federal jurisdiction and various local, state and foreign jurisdictions. The Company’s future effective income tax rates could be unfavorably affected by various factors, including changes in the tax rates as well as rules and regulations in relevant jurisdictions. In addition, the amount of income taxes paid is subject to ongoing audits by U.S. federal, state and local tax authorities and by non-U.S. authorities. If these audits result in assessments different from amounts recorded, the Company’s future financial results may include unfavorable adjustments.

The Company recognizes the importance of developing, implementing, and maintaining cybersecurity measures to ensure the security of our information systems and networks and the confidentiality, availability, and integrity of our data.

Risk management and strategy

The Company continues to build its culture of security and has integrated cybersecurity risk management into our broader enterprise risk management process. This integration ensures that cybersecurity considerations are an integral part of our decision-making processes and operational practices. Our information technology department, including employees dedicated to the area of cybersecurity risk management, works closely with our senior management team to continuously evaluate and address cybersecurity risks in alignment with our business objectives and operational needs. Employees within the information technology department that are focused on cybersecurity attend periodic external training to stay current on potential cybersecurity risks and threats and how to best protect the Company from these risks and threats.

The Company provides training to all employees that reinforces the Company’s information technology risk and security management policies, standards and practices, as well as the expectation that employees comply with these policies. The training assists employees with identifying potential cybersecurity risks and threats and how to protect the Company’s resources and information. This training is mandatory for all employees globally on a periodic basis, and it is supplemented by firmwide internal and external service providers testing initiatives, including frequent phishing tests.

In addition to the employee training program, the Company has created an information security incident response policy and team. The response team includes the Executive Officers of the Company, the Vice President of Information

Technology, the Manager of IT Security, the Vice President of Human Resources and other functional and operational area experts as needed. The risks related to cybersecurity, including the effectiveness of our training programs, are monitored on an ongoing basis by our information technology department and external service providers. In addition, to assess the incident response policy, periodically the Company conducts cybersecurity incident response training exercises to evaluate the effectiveness of the Company’s cybersecurity incident response strategies and tactics.

The Company recognizes the complexity and evolving nature of cybersecurity threats. The Company utilizes a number of third-party software solutions, including full-time external monitoring, that are intended to detect and prevent potential cybersecurity threats. In addition, Gorman-Rupp from time to time engages with a range of external experts, including cybersecurity assessors, consultants, and auditors, in evaluating and testing our risk management systems. These external experts leverage their specialized knowledge and insights on cybersecurity to assess and enhance our internal policies and processes through regular audits, threat assessments, and consultation on security enhancements and strategies.

While we are not aware of any cybersecurity incidents that have materially affected our business operations or financial condition within the prior fiscal year, there can be no guarantee that we will not be the subject of future attacks, threats or incidents that may have a material impact on us. See Item 1A. "Risk Factors – General Risk Factors – Cybersecurity threats" and "Artificial intelligence presents risks and challenges that can impact our business, " which should be read in conjunction with the foregoing information.

Governance

The Board of Directors believes that control and management of risk are primary responsibilities of senior management of the Company. As a general matter, the entire Board of Directors is responsible for oversight of this important senior management function. The Audit Committee is responsible to the Board for the organizational oversight of the Company’s comprehensive enterprise risk management plan, including cyber risks. The Audit Committee is composed of board members with diverse expertise, including risk management, technology, and finance, equipping them to oversee cybersecurity risks effectively.

Senior management plays a pivotal role in informing the Audit Committee on cybersecurity risks. The information technology department regularly informs the Chief Financial Officer (CFO) of all aspects related to cybersecurity risks and incidents. This ensures that senior management is kept abreast of the cybersecurity posture and potential risks. The senior management team presents updates to the Audit Committee quarterly and, as necessary, to the full Board. These regular reports include detailed updates on the Company’s performance preparing for, preventing, detecting, responding to and recovering from cyber incidents, if applicable.

The Company conducts business at plants and offices that are owned or leased and located in the United States and other countries as described below. The following table sets forth the location, approximate size, principal use, markets served, ownership status and utilization of each of our material facilities. Our facilities have the capacity to work three full-time shifts up to seven days per week as well as automated machining running during unstaffed hours, which the Company defines as full utilization. At partial utilization, our facilities are working one fully staffed shift five days per week, supplemented with partial second shifts and running certain automated machining operations during peak periods. We believe we make effective use of our productive capacities at our facilities. We consider our plants, machinery and equipment to be well maintained and in good operating condition. We believe the quality and production capacity of our facilities is sufficient to maintain our competitive position for the foreseeable future.

For over twenty-five years, numerous business entities in the pump and fluid-handling industries, as well as a multitude of companies in many other industries, have been targeted in a series of lawsuits in several jurisdictions by various individuals seeking redress to claimed injury as a result of the entities’ alleged use of asbestos in their products. Since 2001, the Company and some of its subsidiaries have been involved in this mass-scaled litigation, typically as one of many co-defendants in a particular proceeding. The allegations in the lawsuits involving the Company and/or its subsidiaries have been vague, general and speculative. Most of these lawsuits have been dismissed without advancing beyond the early stage of discovery, some as a result of nominal monetary settlements recommended for payment by the Company's insurers. The claims and related legal expenses generally have been covered by the Company's insurance, subject to applicable deductibles and limitations. Accordingly, this series of lawsuits has not, cumulatively or individually, had a material adverse impact on the Company's consolidated results of operations, liquidity or financial condition, nor is it expected to have any such impact in the future, based on the current knowledge of the Company.

In addition, the Company and/or its subsidiaries are parties in a small number of legal proceedings arising in the ordinary course of business. Management does not currently believe that these proceedings will materially impact the Company’s consolidated results of operations, liquidity or financial condition.

Executive Overview

The Gorman-Rupp Company (“we”, “our”, “Gorman-Rupp” or the “Company”) is a leading designer, manufacturer and international marketer of pumps and pump systems for use in diverse water, wastewater, construction, dewatering, industrial, petroleum, original equipment, agriculture, fire suppression, heating, ventilating and air conditioning (HVAC), military and other liquid-handling applications. The Company attributes its success to long-term product quality, applications and performance combined with timely delivery and service, and continually seeks to develop initiatives to improve performance in these key areas.

We regularly invest in training for our employees, in new product development and in modern manufacturing equipment, technology and facilities all designed to increase production efficiency and capacity and drive growth by delivering innovative solutions to our customers. We believe that the diversity of our markets is a major contributor to the generally stable financial growth we have produced historically.

During 2025, based on changes in the agriculture market over the last few years, we took steps intended to optimize our National Pump Company (NPC) footprint. We reduced the number of NPC operating facilities from six to three and expect this change to result in improved profitability by lowering our fixed operating costs with minimal impact on sales. We have transitioned the NPC facility in Olive Branch, MS to our Patterson Pump Company operations to continue to support the growth we have seen in the fire, municipal and industrial markets. During 2025, we recognized $3.0 million in one-time facility optimization costs including inventory rationalization, severance, and facility costs. We expect these changes will result in annualized savings between $2.0 million and $2.5 million in payroll, payroll related, and facility costs. We do not expect future facility optimization costs to be material.

Incoming orders for the year ending December 31, 2025, were $728.4 million, an increase of 10.5%, compared to 2024.

The Company’s backlog of orders was $244.0 million at December 31, 2025 compared to $206.0 million at December 31, 2024, an increase of 18.5%. Approximately 90% of the Company’s backlog of unfilled orders is scheduled to be shipped during 2026, with the remainder principally during the first half of 2027.

On January 22, 2026, the Board of Directors authorized the payment of a quarterly dividend of $0.19 per share, representing the 304th consecutive quarterly dividend to be paid by the Company. During 2025, the Company again paid increased dividends and thereby attained its 53rd consecutive year of increased dividends. These consecutive years of increases continue to position Gorman-Rupp in the top 50 of all U.S. public companies with respect to number of years of increased dividend payments.

The Company currently expects to continue its exceptional history of paying regular quarterly dividends and increased annual dividends. However, any future dividends will be reviewed individually and declared by our Board of Directors at its discretion, dependent on our assessment of the Company’s financial condition and business outlook at the applicable time.

Outlook

As we begin 2026 our outlook remains positive. The 10% increase in incoming orders during 2025 increased our backlog to a healthy $244.0 million. We expect our municipal market to continue to benefit from infrastructure spending, including strong demand for flood control and storm water management, and expect a number of our markets to continue to benefit from increased demand related to data center construction. Our strong cash flow positions us well to further reduce our debt and interest expense going forward.

Results of Operations – Year ended December 31, 2025 compared to year ended December 31, 2024:

Net Sales

Net sales for 2025 were $682.4 million compared to net sales of $659.7 million for 2024, an increase of 3.4% or $22.7 million. Sales increased in the majority of our markets, including sales increases of $8.1 million in the industrial market and $6.6 million in the fire suppression market due in part to increased demand related to data centers. Net sales also increased $5.2 million in the repair market, $4.9 million in the OEM market, $3.4 million in the municipal market, $2.4 million in the agriculture market, and $1.5 million in the petroleum market. Offsetting these increases was a decrease of $9.4 million in the construction market due to a general slowdown in construction activity, including sales into the rental market.

Cost of Products Sold and Gross Profit

Gross profit was $209.1 million for 2025, resulting in gross margin of 30.6%, compared to gross profit of $204.3 million and gross margin of 31.0% for the same period in 2024. Gross profit for 2025 included $2.7 million of one-time facility optimization costs. The 40 basis point decrease in gross margin was the result of one-time facility optimization costs recognized in the third quarter of 2025.

Selling, General and Administrative (SG&A) Expenses

Selling, general and administrative (“SG&A”) expenses were $101.4 million and 14.9% of net sales for 2025 compared to $100.5 million and 15.2% of net sales for the same period in 2024.

Operating Income

Operating income was $95.4 million for 2025, resulting in an operating margin of 14.0%, compared to operating income of $91.4 million and an operating margin of 13.9% for the same period in 2024. Operating income for 2025 included $3.0 million of facility optimization costs. The 10 basis point increase in operating margin compared to the same period in 2024 was driven by improved leverage on labor, overhead, and SG&A expenses partially offset by facility optimization costs.

Interest Expense

Interest expense was $23.4 million for 2025 compared to $33.6 million for the same period in 2024. The decrease in interest expense was due to a series of debt refinancing transactions the Company completed on May 31, 2024, as well as a decrease in outstanding debt.

Other Income (Expense), net

Other income (expense), net was $2.8 million of expense for 2025 compared to $7.3 million of expense for the same period in 2024. Other expense for 2025 included non-cash pension settlement charges of $1.2 million. Other expense for 2024 included a $4.4 million write-off of unamortized previously deferred debt financing fees and a $1.8 million prepayment fee related to the early retirement of a subordinated credit facility.

Net Income

Net income was $53.0 million, or $2.02 per share, for 2025, compared to net income of $40.1 million, or $1.53 per share, for 2024. Adjusted earnings per share for 2025 and 2024 were $2.14 and $1.75 per share, respectively. Adjusted earnings per share is a non-GAAP financial measure, please see "Non-GAAP Financial information" below.

The Company’s effective tax rate was 23.3% for 2025 compared to 20.6% for 2024. The increase in the rate was driven by changes in U.S. tax regulations passed under the One Big Beautiful Bill Act. The updated tax regulations accelerated temporary tax benefits that reduced our foreign tax benefits and made them permanent, thus increasing our effective tax rate. We expect our effective tax rate for 2026 to be between 21.0% and 23.0%.

Results of Operations – Year ended December 31, 2024 compared to year ended December 31, 2023:

Information pertaining to fiscal year 2023 was included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 beginning on page 15 under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which was filed with the SEC on February 26, 2024.

Non-GAAP Financial Information:

This discussion of Results of Operations includes certain non-GAAP financial data and measures such as adjusted earnings, adjusted earnings per share, and adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”). Adjusted earnings is earnings excluding the write-off of unamortized previously deferred debt financing fees, refinancing costs, facility optimization costs, non-cash pension settlement charges, and amortization of acquired customer backlog. Adjusted earnings per share is earnings per share excluding the write-off of unamortized previously deferred debt financing fees per share, refinancing costs per share, facility optimization costs per share, non-cash pension settlement charges per share, and amortization of acquired customer backlog per share. Adjusted EBITDA is net income (loss) excluding interest, taxes, depreciation and amortization, adjusted to exclude the write-off of unamortized previously deferred debt financing fees, refinancing costs, facility optimization costs, non-cash pension settlement charges, amortization of acquired customer backlog, and non-cash LIFO expense. Management utilizes these adjusted financial data and measures to assess comparative operations against those of prior periods without the distortion of non-comparable factors. The inclusion of these adjusted measures should not be construed as an indication that the Company’s future results will be unaffected by unusual or infrequent items or that the items for which the Company has made adjustments are unusual or infrequent or will not recur. Further, the impact of the LIFO inventory costing method can cause results to vary substantially from company to company depending upon whether they elect to utilize LIFO and depending upon which method they may elect. The Gorman-Rupp Company believes that these non-GAAP financial data and measures also will be useful to investors in assessing the strength of the Company’s underlying operations and liquidity from period to period. These non-GAAP financial measures are not intended to replace GAAP financial measures, and they are not necessarily standardized or comparable to similarly titled measures used by other companies. Provided below is a reconciliation of adjusted earnings, adjusted earnings per share, and Adjusted EBITDA to their respective corresponding GAAP financial measures, which includes a description of actual adjustments made in the current period and the corresponding prior period.

Liquidity and Capital Resources

Our primary sources of liquidity are cash generated from operations and borrowings under our revolving credit facility. Cash and cash equivalents totaled $35.1 million at December 31, 2025. The Company had $99.4 million of borrowing capacity available under the revolving credit facility after deducting $0.6 million in outstanding letters of credit primarily related to customer orders. See Note 4 - Financing Arrangements in the Notes to our Consolidated Financial Statements.

As of December 31, 2025, the Company had $280.8 million in debt outstanding due in 2029 and $30.0 million due in 2031. The Company was in compliance with its debt covenants, including limits on additional borrowings and maintenance of certain operating and financial ratios, at December 31, 2025.

Capital expenditures in 2025 were $17.4 million and consisted primarily of machinery and equipment and building improvements. Capital expenditures for 2026, which are expected to consist principally of machinery and equipment purchases, are estimated to be approximately $20.0 - $22.0 million and are expected to be financed through cash from operations. During 2025, 2024 and 2023, the Company financed its capital improvements and working capital requirements principally through internally generated funds.

The Company contributed $2.7 million to its defined benefit pension plan in 2025 and expects to contribute up to $2.9 million to its defined benefit pension plan in 2026.

Financial Cash Flow

The increase in cash provided by operating activities in 2025 compared to 2024 was primarily due to increased net income and an increase in operating liabilities. The increase in cash provided by operating activities in 2024 compared to 2023 was primarily due to increased earnings before depreciation, amortization, and LIFO expense, and improved cash flow from working capital management.

During 2025, net cash used for investing activities of $15.3 million consisted primarily of $17.4 million used for capital expenditures, largely related to machinery and equipment, partially offset by $1.8 million of proceeds from the sale of property plant and equipment. During 2024, net cash used for investing activities of $11.9 million consisted primarily of $14.3 million used for capital expenditures, largely related to machinery and equipment, partially offset by $2.5 million in proceeds from the sale of property, plant, and equipment. During 2023, net cash used for investing activities of $20.2 million consisted primarily of $20.8 million used for capital expenditures, largely related to machinery and equipment.

During 2025, net cash used for financing activities of $80.9 million consisted primarily of net payments on bank borrowings of $60.0 million and dividend payments of $19.6 million. During 2024, net cash used for financing activities of $63.1 million consisted primarily of net payments on bank borrowings of $43.0 million and dividend payments of $19.0 million. During 2023, net cash used for financing activities of $54.5 million consisted primarily of net payments on bank borrowings of $34.5 million, dividend payments of $18.4 million.

Maturities of long-term debt in the next five fiscal years, and the remaining years thereafter, are as follows:

The Company was in compliance with its debt covenants, including limits on additional borrowings and maintenance of certain operating and financial ratios at December 31, 2025 and December 31, 2024. We believe we have adequate liquidity from funds on hand and borrowing capacity to execute our financial and operating strategy, as well as comply with debt obligations and financial covenants for at least the next 12 months.

The Company currently expects to continue its exceptional history of paying regular quarterly dividends and increased annual dividends. However, any future dividends will be reviewed individually and declared by our Board of Directors at its discretion, dependent on our assessment of the Company’s financial condition and business outlook at the applicable time.

The Board of Directors has authorized a share repurchase program of up to $50.0 million of the Company’s common shares, of which approximately $48.1 million has yet to be repurchased. The actual number of shares repurchased will depend on prevailing market conditions, alternative uses of capital and other factors, and will be determined at management’s discretion. The Company is not obligated to make any purchases under the program, and the program may be suspended or discontinued at any time.

Contractual Obligations

Capital commitments in the table below include contractual commitments to purchase machinery and equipment that have been approved by the Board of Directors. The capital commitments do not represent the entire anticipated purchases in the future but represent only those substantive items for which the Company is contractually obligated as of December 31, 2025. Also, the Company has operating leases and financing leases for certain offices, manufacturing facilities, land, office equipment and automobiles. Rental expenses relating to these leases were $3.7 million in 2025, $3.6 million in 2024, and $2.8 million in 2023.

The following table summarizes the Company’s contractual obligations at December 31, 2025:

Critical Accounting Policies

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States. When more than one accounting principle, or the method of its application, is generally accepted, management selects the principle or method that is appropriate in the Company’s specific circumstances. Application of these accounting principles requires management to make estimates about the future resolution of existing uncertainties; as a result, actual results could differ from these estimates.

In preparing these Consolidated Financial Statements, management has made its best estimates and judgments of the amounts and disclosures included in the Consolidated Financial Statements, giving due regard to materiality. The Company does not believe there is a great likelihood that materially different amounts would be reported under different conditions or using different assumptions pertaining to the accounting policies described below.

Revenue Recognition

The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers,” under which the unit of account is a performance obligation. Substantially all of our revenue is derived from fixed-price customer contracts and the majority of our customer contracts have a single performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to a customer. For customer contracts with multiple performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price, which is generally determined based on standalone selling prices charged to customers or using expected cost plus margin.

The transaction price for a customer contract is allocated to each distinct performance obligation and recognized as revenue when, or as, the Company’s performance obligation is satisfied. All of the Company's performance obligations, and associated revenue, are generally satisfied at a point in time, with the exception of certain highly customized pump products, which are satisfied over time as work progresses.

Accounting for long-term contracts involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognizes that profit as performance obligations are satisfied. Contract estimates are based on various assumptions to project the outcome of future events that could span longer than one year. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials and the performance of subcontractors as applicable.

As a significant change in one or more of these estimates could affect the profitability of our contracts, the Company reviews and updates its contract-related estimates regularly. Adjustments in estimated profit on contracts are accounted for under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate.

Inventories and Related Allowance

Inventories are valued at the lower of cost or market value and have been reduced by an allowance for excess and obsolete inventories. The estimated allowance is based on a variety of factors, including historical inventory usage and management evaluations. Historically, the Company has not experienced substantive write-offs due to obsolescence. The Company uses the last-in, first-out (LIFO) method for the majority of its inventories.

Pension Plans and Other Postretirement Benefit Plans

The Company recognizes the obligations associated with its defined benefit pension plan and defined benefit health care plans in its Consolidated Financial Statements. The measurement of liabilities related to its pension plan and other postretirement benefit plans is based on management’s assumptions related to future events including interest rates, return on pension plan assets, rate of compensation increases and health care cost trend rates. Actual pension plan asset performance will either reduce or increase pension losses included in accumulated other comprehensive loss, which ultimately affects net income. The discount rates used to determine the present value of future benefits are based on estimated yields of investment grade fixed income investments.

The discount rates used to value pension plan obligations were 5.0% at December 31, 2025 and 5.3% at December 31, 2024. The discount rates used to value postretirement obligations were 5.1% at December 31, 2025 and 5.4% at December 31, 2024. The discount rates were determined based on the plan distinct projected cash flow and the Gallagher Regular yield curves. The expected rate of return on pension assets is designed to be a long-term assumption that will be subject to year-to-year variability. The rate for 2025 was 6.5% and for 2024 was 7.2%. Actual pension plan asset performance will either reduce or increase unamortized losses included in Accumulated other comprehensive loss, which will ultimately affect net income. The assumed rate of compensation increase was 3.5% in both 2025 and 2024.

Substantially all eligible retirees elect to take lump sum settlements of their pension plan benefits. When interest rates are low, this subjects the Company to the risk of exceeding an actuarial threshold computed on an annual basis and triggering a GAAP-required non-cash pension settlement loss, which occurred in 2025.

The assumption used for the rate of increase in medical costs over the next five years was 5.0% in 2025 and 4.8% in 2024.

Goodwill and Other Intangibles

The Company accounts for goodwill in a purchase business combination as the excess of the cost over the fair value of net assets acquired. Business combinations can also result in other intangible assets being recognized. Amortization of intangible assets, if applicable, occurs over their estimated useful lives.

Goodwill is tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be a possible permanent loss of value in accordance with ASC 350, “Intangibles - Goodwill and Other.”

Goodwill is tested for impairment at the reporting unit level and is based on the net assets for each reporting unit, including goodwill and intangible assets. The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing a quantitative impairment assessment is unnecessary.

In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we identify and assess relevant drivers of fair value and events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involves significant judgments and assumptions. The judgments and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Company-specific events and share price trends and making the assessment on whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact.

When performing a quantitative assessment of goodwill impairment if necessary, or in years where we elect to do so, a discounted cash flow model and a market based approach are used to estimate the fair value of each reporting unit. The discounted cash flow model considers forecasted cash flows discounted at an estimated weighted-average cost of capital. The forecasted cash flows are based on the Company’s long-term operating plan and the weighted-average cost of capital is an estimate of the overall after-tax rate of return. Discount rate assumptions are based on an assessment of the risk inherent in the future cash flows of the respective reporting units. The market based approach considers market multiples of corporations engaged in the same or similar line of business.

The Company performed qualitative analyses as of October 1, 2025 and 2024 for all of its reporting units except for National Pump Company (“National”) and Fill-Rite, concluding that it was more likely than not that the fair value of the reporting units exceeded the respective carrying amounts.

The Company performed a quantitative impairment analysis as of October 1, 2025 for National and Fill-Rite reporting units and concluded that the fair value of each reporting unit exceeded its carrying value by approximately 22% and 6% respectively, and therefore were not impaired. A sensitivity analysis was performed for each reporting unit, assuming a hypothetical 50 basis point decrease in the expected long-term growth rate or a hypothetical 50 basis point increase in the weighted average cost of capital, and both scenarios independently yielded an estimated fair value above carrying value. If National or Fill-Rite fail to experience growth or revise their long-term projections downward, they could be subject to impairment charges in the future. Goodwill relating to the National reporting unit is $13.6 million, or 1.6% of the Company’s December 31, 2025 total assets, and goodwill relating to the Fill-Rite reporting unit is $230.7 million, or 26.8% of the

Company’s December 31, 2025 total assets. See Note 9 to the Consolidated Financial Statements, Goodwill and Other Intangible Assets.

Other indefinite-lived intangible assets primarily consist of trademarks and trade names. The fair value of these assets is also tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be a possible permanent loss of value. The fair value of these assets is determined using a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows and profitability. For 2025 and 2024, the fair value of all indefinite lived intangible assets exceeded the respective carrying values.

Finite-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recovered through future net cash flows generated by the assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future net undiscounted cash flows estimated to be generated by such assets. The Company was not aware of any events or changes in circumstances that indicate the carrying value of its finite-lived assets may not be recoverable. See Note 9 to the Consolidated Financial Statements, Goodwill and Other Intangible Assets.

Acquisitions

The Company allocates the purchase price of its acquisitions to the assets acquired, liabilities assumed, and noncontrolling interests based upon their respective fair values at the acquisition date. The Company utilizes management estimates and inputs from an independent third-party valuation firm to assist in determining these fair values.

The Company uses the income, market or cost approach (or a combination thereof) for the valuation as appropriate. The valuation inputs in these models and analyses are based on market participant assumptions. Management values property, plant and equipment using the cost approach supported where available by observable market data, which includes consideration of obsolescence. Management values acquired intangible assets using the relief from royalty method or excess earnings method, which are forms of the income approach supported by observable market data for peer companies. The significant assumptions used to estimate the value of the acquired intangible assets include discount rates and certain assumptions that form the basis of future cash flows (such as revenue growth rates, EBITDA margins, customer attrition rates, and royalty rates), which are considered Level 3 assets as the assumptions are unobservable inputs developed by the Company. Acquired inventories are recorded at fair value. For certain items, the carrying value is determined to be a reasonable approximation of fair value based on information available to the Company.

The excess of the acquisition price over estimated fair values is recorded as goodwill. Goodwill is adjusted for any changes to acquisition date fair value amounts made within the measurement period. Acquisition-related transaction costs are recognized separately from the business combination and expensed as incurred.

Other Matters

Certain transactions with related parties occur in the ordinary course of business and are not considered to be material to the Company’s consolidated financial position, net income or cash flows.

The Company does not have any off-balance sheet arrangements, financings or other relationships with unconsolidated “special purpose entities.”

The Company is exposed to various market risks, including changes in foreign currency exchange rates and interest rates. Exposure to foreign exchange rate risk is due to certain costs and revenue being denominated in currencies other than one of the Company’s subsidiaries functional currency. The Company is also exposed to market risk as the result of changes in interest rates which may affect the cost of financing. We continually monitor these risks and regularly develop appropriate strategies to manage them. Accordingly, from time to time, we may enter into certain derivative or other financial instruments. These financial instruments are used to mitigate market exposure and are not used for trading or speculative purposes.

Interest Rate Risk

The results of operations are exposed to changes in interest rates primarily with respect to borrowings under the Company’s Senior Term Loan Facility and Credit Facility. Borrowings under the Senior Term Loan Facility and Credit Facility may be made either at (i) a base rate plus the applicable margin, which ranges from 0.50% to 1.25%, or at (ii) an Adjusted Term SOFR Rate, plus the applicable margin, which ranges from 1.5% to 2.25%. At December 31, 2025, the Company had $280.8 million in borrowings under the Senior Term Loan Facility and no borrowings under the Credit Facility. As of December 31, 2025, the applicable interest rates under the Senior Secured Credit Agreement were Adjusted Term SOFR plus 2.0%. See Note 4 - Financing Arrangements in the notes to our Consolidated Financial Statements.

To reduce the exposure to changes in the market rate of interest, effective October 31, 2022, the Company entered into interest rate swap agreements for a portion of the Senior Term Loan Facility. Terms of the interest rate swap agreements require the Company to receive a fixed interest rate and pay a variable interest rate. The interest rate swap agreements are designated as a cash flow hedge, and as a result, the mark-to-market gains or losses will be deferred and included as a component of accumulated other comprehensive income (loss) and reclassified to interest expense in the period during which the hedged transactions affect earnings. See “Derivative Financial Instruments” and “Interest Rate Derivatives” in the Notes to our Consolidated Financial Statements.

The Company estimates that a hypothetical increase of 100 basis points in interest rates would increase interest expense by approximately $1.5 million on an annual basis.

Foreign Currency Risk

The Company’s foreign currency exchange rate risk is limited primarily to the Euro, Canadian Dollar, South African Rand and British Pound. The Company manages its foreign exchange risk principally through invoicing customers in the same currency as is used in the market of the source of products. The foreign currency transaction gains (losses) for 2025, 2024 and 2023 were $(0.3) million, $(0.4) million and $(0.4) million, respectively, and are reported within Other (expense) income, net on the Consolidated Statements of Income.

Evaluation of Disclosure Controls and Procedures

The Company maintains a set of disclosure controls and procedures designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. The Company’s disclosure controls and procedures are also designed to ensure that information required to be disclosed in Company reports filed under the Securities Exchange Act of 1934 is accumulated and communicated to the Company’s management, including the principal executive officer and the principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

An evaluation was carried out under the supervision and with the participation of the Company’s management, including the principal executive officer and the principal financial officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this report on Form 10-K. Based on the evaluation, the principal executive officer and the principal financial officer have concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2025.

Report of Management on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). Internal control over financial reporting is a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers, or persons performing similar functions, and affected by the Company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States.

The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and Directors of the Company; and (iii) 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. In addition, 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.

Management conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO Criteria).

Based on its evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2025.

The independent registered public accounting firm of Ernst & Young LLP that has audited the consolidated financial statements included in this annual report on Form 10-K, has also issued an attestation report on the Company’s internal control over financial reporting as of December 31, 2025. This report is included on the following page.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of The Gorman-Rupp Company

Opinion on Internal Control Over Financial Reporting

We have audited The Gorman-Rupp Company’s 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, The Gorman-Rupp Company (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 2024 consolidated financial statements of the Company and our report dated March 2, 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 Report of Management 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.
