GENERAL

At Pentair, we help the world sustainably move, improve and enjoy water, life’s most essential resource. From our residential and commercial water solutions to industrial water management and everything in between, Pentair is an S&P 500 company focused on smart, sustainable water solutions that help our planet and people thrive.

Pentair strategy

Our vision is to be the world’s most valued sustainable water solutions company for our employees, customers and shareholders. As a company, we:

•Focus on growth in our core businesses and strategic initiatives;

•Accelerate digital innovation and technology as well as sustainability investments;

•Expedite growth and drive margin expansion through our Transformation Program; and

•Build a high performance growth culture and deliver on our commitments while living our Win Right values.

HISTORY AND DEVELOPMENT

We are an Irish public limited company that was formed in 2014. We are the successor to Pentair Ltd., a Swiss corporation formed in 2012, and Pentair, Inc., a Minnesota corporation formed in 1966 and our wholly-owned subsidiary, under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Although our jurisdiction of organization is Ireland, we manage our affairs so that we are centrally managed and controlled in the United Kingdom (the “U.K.”) and therefore have our tax residency in the U.K.

On September 17, 2025, as part of our Flow reportable segment, we completed the acquisition of Hydra-Stop, LLC (“Hydra-Stop”) for $292.1 million in cash, net of cash acquired, and subject to customary adjustments. Hydra-Stop manufactures specialty insertion valves, line stop fittings and installation equipment.

In December 2024, as part of our Pool reportable segment, we completed the acquisition of G & F Manufacturing, LLC (“G & F Manufacturing”) for $116.0 million in cash, net of cash acquired. The net purchase price was comprised of an upfront cash payment of $108.0 million, and the estimated fair value at the acquisition date of a contingent earn-out liability based upon the achievement of certain defined operating results in the two years following the acquisition. G & F Manufacturing manufactures and services pool heat pumps.

Our registered principal office is located at Regal House, 70 London Road, Twickenham, London, TW13QS United Kingdom. Our management office in the United States (“U.S.”) is located at 5500 Wayzata Boulevard, Suite 900, Golden Valley, Minnesota.

BUSINESS AND PRODUCTS

Pentair is comprised of three reportable segments: Flow, Water Solutions and Pool. The discussions below refer to the Company’s reportable segment composition and business activities as of and prior to December 31, 2025. Effective January 1, 2026, we reorganized the composition of our Flow and Water Solutions reportable segments to move our residential and irrigation flow business from our Flow segment to our Water Solutions segment. For further detail on the changes to the Flow and Water Solutions segments as a result of the revised segmentation effective January 1, 2026, refer to the discussion titled “2026 Segment Structure” below. Additional information regarding this revised segmentation is found under the section titled “2026 Revised Segmentation.”

Flow

The Flow segment aims to deliver water where it is needed, when it is needed, more efficiently and to transform waste into value. This segment designs, manufactures and sells a variety of fluid treatment and pump products and systems, including pressure vessels, gas recovery solutions, membrane bioreactors, wastewater reuse systems and advanced membrane filtration, separation systems, specialty insertion valves, line stop fittings and installation equipment, water disposal pumps, water supply pumps, fluid transfer pumps, turbine pumps, solid handling pumps, and agricultural spray nozzles, while serving the global residential, commercial and industrial markets. These products and systems are used in a range of applications, including fluid delivery, ion exchange, desalination, food and beverage, separation technologies for the oil and gas industry, residential and

municipal wells, water treatment, wastewater solids handling, pressure boosting, circulation and transfer, fire suppression, flood control, agricultural irrigation and crop spray.

For the fiscal year ended December 31, 2025, our residential and irrigation flow businesses, which sell pumps focused on residential and agriculture, comprised approximately 36% of Flow sales. Another approximately 30% of Flow sales were from the commercial and infrastructure flow businesses, which sell larger pumps focused on fire suppression, water supply, wastewater and flood control. The remaining approximately 34% of Flow sales were from the industrial solutions business, comprised of applications focused on industrial process and air filtration and sustainable gas.

Flow brand names include Pentair Flow, Aurora, Berkeley, Codeline, Fairbanks-Nijhuis, Haffmans, Hydromatic, Hypro, Jung Pumpen, Myers, Sta-Rite, Shurflo, Südmo and X-Flow.

Customers

Flow customers include businesses engaged with end users, and wholesale and retail distribution in the residential, agricultural, commercial, food and beverage, and industrial vertical markets.

Seasonality

We have historically experienced increased demand following warm weather trends for residential water supply and agricultural products. Such demand historically has been at seasonal highs from April to August. Seasonal effects may vary from year to year and are impacted by weather patterns, particularly by temperatures, heavy flooding and droughts.

Competition

Flow faces numerous domestic and international competitors, some of which have substantially greater resources directed to the vertical markets in which we compete. Competition focuses on brand names, product performance (including energy-efficient offerings and required specifications), quality, service and price. We compete by offering a wide variety of innovative and high-quality products, which we believe are competitively priced.

2026 Segment Structure

Effective January 1, 2026, we moved our residential and irrigation flow business from our Flow segment to our Water Solutions segment. As a result, the products previously within the residential and irrigation flow business are now part of the Water Solutions reportable segment. These products, including fluid transfer pumps, agricultural spray nozzles, as well as certain water disposal and water supply pumps, are used in various applications such as circulation and transfer, agricultural irrigation and crop spray. The residential and irrigation flow business includes brand names such as Berkeley, Hypro, Jung Pumpen, Sta-Rite and Shurflo. Given this change, the Flow segment will no longer serve wholesale and retail distribution customers in residential or agricultural markets. Additionally, the commercial and infrastructure flow and industrial solutions businesses have not historically been impacted by seasonal weather trends. This change does not impact the competitive landscape of the Flow segment.

Water Solutions

The Water Solutions segment aims to provide great tasting, higher-quality water and ice while helping people use water more productively. This segment designs, manufactures and sells commercial and residential water treatment products and systems including pressure tanks, control valves, activated carbon products, commercial ice machines, conventional filtration products, and point-of-entry and point-of-use water treatment systems. These water treatment products and systems are for use in residential whole home water filtration, drinking water filtration and water softening solutions in addition to commercial water management and filtration in foodservice operations.

For the fiscal year ended December 31, 2025, our commercial business, which offers products such as conventional filtration products, commercial point-of-entry and point-of-use water treatment systems, activated carbon products and commercial ice machines, comprised approximately 66% of Water Solutions sales. The other approximately 34% of Water Solutions sales were associated with our residential business, which primarily focuses on products associated with residential point of entry and point of use filtration and softening systems, pressure tanks and control valves.

Water Solutions brand names include Pentair Water Solutions, Everpure, Fleck, Manitowoc Ice, Pentek and RainSoft.

Customers

Water Solutions customers include businesses engaged in wholesale and retail distribution in the residential, commercial and food and beverage vertical markets. Customers also include end users, consumers and original equipment manufacturers.

Seasonality

We experience seasonal demand with several end customers and end users within Water Solutions. End-user demand for water solution products generally follows warm weather trends and is at seasonal highs from April to September.

Competition

Water Solutions faces numerous domestic and international competitors, some of which have substantially greater resources directed to the vertical markets in which we compete. Competition focuses on brand names, product performance (including required specifications), quality and price. We compete by offering a wide variety of innovative and high-quality products, which we believe are competitively priced. We believe our distribution channels and reputation for quality also provide us a competitive advantage.

2026 Segment Structure

Effective January 1, 2026, we moved our residential and irrigation flow business from our Flow segment to our Water Solutions segment. As a result, the products previously included in the residential and irrigation flow business within our Flow segment are now part of the Water Solutions reportable segment. These products, including fluid transfer pumps, agricultural spray nozzles, as well as certain water disposal and water supply pumps, are used in various applications such as circulation and transfer, agricultural irrigation and crop spray. With this change, the Water Solutions segment now includes brands such as Berkeley, Hypro, Jung Pumpen, Sta-Rite and Shurflo and will serve customers in agricultural markets. Historically, the residential and irrigation flow business has been influenced by warm weather trends and other weather events such as heavy flooding and drought. This change does not impact the competitive landscape of the Water Solutions segment.

Pool

The Pool segment aims to provide innovative, energy-efficient pool solutions to help people more sustainably enjoy water. This segment designs, manufactures and sells a complete line of energy-efficient residential and commercial pool equipment and accessories including pumps, filters, heaters, lights, automatic controls, chlorinators, automatic cleaners, maintenance equipment and pool accessories. Applications for our pool products include residential and commercial pool maintenance, pool repair, renovation, service, construction and aquaculture solutions.

The primary brand names associated with the Pool segment are Pentair Pool, Kreepy Krauly, Pleatco and Sta-Rite.

Customers

Pool customers include businesses engaged in wholesale and retail distribution in the residential and commercial vertical markets. Customers in the residential and commercial verticals also include end users and consumers.

One customer in the Pool business represented approximately 18% and 15% of our consolidated net sales in 2025 and 2024, respectively.

Seasonality

We have historically experienced seasonal demand with several end customers and end users. End-user demand for pool equipment follows warm weather trends and historically has been at seasonal highs from April to August. The magnitude of the sales spike has historically been partially mitigated by employing advance sale “early buy” programs (generally including extended payment terms and/or additional discounts).

Competition

Pool faces numerous domestic and international competitors, some of which have substantially greater resources directed to the vertical markets in which we compete. Competition focuses on brand names, product performance (including energy-efficient offerings and required specifications), quality, service and price. We compete by offering a wide variety of innovative and high-quality products, which we believe are competitively priced. We believe our distribution channels and reputation for quality also provide us a competitive advantage.

2026 REVISED SEGMENTATION

Effective January 1, 2026, we reorganized the composition of our Flow and Water Solutions reportable segments to reflect how we are managing our business beginning in 2026. As a result of this reorganization, our residential and irrigation flow business moved from our Flow segment into our Water Solutions segment. The Pool segment remains unchanged. We believe the new alignment with our residential and irrigation flow business in our Water Solutions segment will help us accelerate our efforts to improve customer experiences, enhance operational efficiencies and deliver more comprehensive solutions. All historical segment information presented throughout this Annual Report on Form 10-K, with the exception of the table below, was prepared based on the reporting segment structure in place during 2025.

INFORMATION REGARDING ALL REPORTABLE SEGMENTS

Research and development

We conduct research and development activities primarily in our own facilities. These efforts consist mostly of the development of new products, product applications and manufacturing processes.

Raw materials

The principal materials we use in manufacturing our products are mild steel, stainless steel, electronic components (including drives and motors), plastics (resins, fiberglass, epoxies), metals and paint (powder and liquid). In addition to the purchase of raw materials, we purchase some finished goods for distribution for resale.

We purchase the materials we use in various manufacturing processes on the open market. We believe the majority of such materials are available through multiple sources and in adequate supply. We have certain long-term commitments, principally price commitments, for the purchase of various component parts and raw materials and continue to work with our suppliers to maintain delivery continuity. Alternate sources of supply are available for most materials and we believe that the termination of any of these commitments would not have a material adverse effect on our financial position, results of operations or cash flows.

Certain commodities, such as metals and resins, are subject to commodity market and duty-driven price fluctuations. We manage these fluctuations through several mechanisms, including long-term agreements with price adjustment clauses for significant commodity market movements in certain circumstances. Prices for raw materials, such as metals and other commodities, have trended higher due to volatile market trends and enacted tariffs and may continue to trend higher in the future.

Intellectual property

Patents, non-compete agreements, proprietary technologies, customer relationships, trademarks, trade names and brand names are important to our business. However, we do not regard our business as being materially dependent upon any single patent, non-compete agreement, proprietary technology, customer relationship, trademark, trade name or brand name.

Patents, patent applications and license agreements will expire or terminate over time by operation of law, in accordance with their terms or otherwise. We do not expect the termination of patents, patent applications or license agreements to have a material adverse effect on our financial position, results of operations or cash flows.

Human capital resources

We believe our success depends on our ability to attract, develop and retain strong employees. We believe a deep-rooted culture energizes our employees to make a difference within and beyond the workplace. We strive to be the destination for top talent, and work hard to develop and retain high performers throughout their career. We also believe our Win Right values, positive culture and commitment to inclusion and belonging foster innovation and curiosity, which, in turn, can contribute to us being an industry leader.

As of December 31, 2025, we had approximately 9,000 employees worldwide, of which approximately 49% are located in the U.S. A small portion of our U.S. employees are unionized. Outside the U.S. we have employees in certain countries, primarily in Europe, who are represented by an employee representative organization, such as a union, works council or employee association.

Employee engagement and development

We believe engaging our employees and developing their careers is important to our long-term success and ties directly to our Win Right culture and values. We support our Win Right culture by providing dedicated culture training to our employees globally. We engage with our employees and gather feedback about our employee programs, practices and policies through various approaches that include town hall meetings where Pentair leaders share strategies and perspectives and answer questions; quarterly leadership meetings to communicate our results and expectations; and an annual senior leadership meeting to drive growth and productivity initiatives, share best practices, and invest in our leaders. In addition, we conduct employee engagement and pulse surveys during the year to gauge the level of engagement and potential actions needed on culture, the business, employee experience and retention. We believe in transparency with our employees and provide the results of those surveys to the manager level and above, which drive the development of action plans. Additionally, we provide a high-level overview of survey results in the employee town halls following finalization of survey results.

Training and development

To support employees in their career journey, we have developed and shared, through our dedicated development site, a number of tools and resources. We offer career pathing and development resources for all functions throughout Pentair. We support development annually with a dedicated career week, individual development planning and targeted development experiences supported through live training sessions; on-demand eLearning, virtual classrooms and downloadable materials. Additionally, our annual talent management process supports employees to set objectives, receive feedback and development and build development plans with their leaders.

Our talent development efforts span across various levels of our organization, including our early career Leadership Development Program, a 36-month program in which potential future leaders participate in rotations intended to develop their capabilities through organization-wide exposure, and our Growth Manager Development Program that prepares both new and experienced managers to be more effective and inclusive leaders at Pentair. In addition, our Senior Leadership Development Program supports our senior leaders in driving growth and high performance by strengthening enterprise leadership, team effectiveness and business systems.

Inclusion

Our commitment to inclusion is part of living our Win Right values. Our success also depends on our ability to attract, engage, develop and retain our employees, which includes diverse employees from an array of backgrounds. We believe an inclusive and diverse workforce contributes different perspectives and innovative ideas that enable us to improve. We believe that every employee should be provided the same opportunity to be heard, respected, have a sense of belonging and contribute to our mission. Our Business Resource Groups, which are open to everyone, have been established to help promote a culture of inclusion by providing an additional forum for employee feedback, such as sharing insights that could help the business improve, and sponsoring awareness, education and engagement.

We take an integrated approach to supporting and promoting workplace inclusion by fostering a globally aware, inclusive culture; and reinforcing our practices to be fair and nondiscriminatory. We have various training and organizational approaches dedicated to fostering inclusion, including Business Resource Groups led by employees; Pentair’s Code of Business Conduct and Ethics; and other resources on our company’s intranet.

Health, safety and wellness

We are committed to providing a safe workplace for all of our employees. We encourage employees to stop work anytime there is a potential concern regarding worker safety and promote an open-door policy so that all of our employees feel free to speak to their manager if there are any potential health, safety, compliance or sustainability concerns. Additionally, each site maintains a confidential reporting process, and we encourage the use of the Ethics Hotline for employees to report anonymously potential safety concerns. All locations, enterprise wide, are required to meet regulatory agency standards as applicable to each site’s location.

Compensation and benefits

In the U.S., non-union full-time employees are eligible to receive the following benefits: short-term and long-term disability insurance; flexible and health savings accounts and wellness programs; health insurance (medical, pharmacy, dental); eight weeks paid parental leave for birth, adoptive and foster parents; two weeks paid caregiver leave; legal services; retirement benefits; employee stock purchase plan; tuition reimbursement; holidays; vacation and sick time. Benefits for union employees may vary.

Sustainability Activities

As a leading provider of smart, sustainable water solutions and with a foundation of Win Right values, we recognize that the work we do and the products we provide help to improve lives and the environment around the world. We are focused on building on our Win Right values and culture by contributing to the development of a sustainable and responsible society, which we believe will also drive our future growth. We have established formal sustainability programs to further advance environmental sustainability. Additionally, we are dedicated to further integrating our sustainability strategy throughout our business by creating accountability for targets and shared commitments.

In 2025, Pentair completed its second environmental, social and governance assessment in alignment with the European Union’s 2023 Corporate Sustainability Reporting Directive framework (“CSRD”). This assessment informed our updated Sustainability Strategic Targets which we announced in 2025. We plan to regularly update this assessment to support sustainability strategic planning and risk management, to set future targets and to make disclosures in accordance with the CSRD and other requirements.

Annually, we publish a sustainability report on our environmental sustainability efforts, related activities and accomplishments, which can be found on our corporate website, and is not incorporated by reference into this Annual Report on Form 10-K.
