The Pentair 2025 Sustainability Report showcases the Company's efforts to support a more sustainable future.

In the Report, Pentair highlights its efforts toward Making Better Essential, including the achievement of its Water Stewardship and Product Design for Sustainability targets, with continued progress towards its Greenhouse Gas Emissions Reduction target.

"At Pentair, we believe that water is life's most essential resource," said John Stauch, Pentair President and CEO. "This report shares how, together with our customers, we are building a better future that is not only more resilient for our business but also for people and the planet."

Pentair shared the following updates on its Sustainability Strategic Targets, which are guided by its purpose to create a better world for people and the planet through smart, sustainable water solutions:

Water Stewardship Target:

In 2025, Pentair met its annual Sustainability Strategic Target focused on water stewardship by restoring 100% of water withdrawal by manufacturing sites in high-water-stress areas, representing approximately 31 million gallons of water restored to high-water-stress areas.¹

Additionally, Pentair advanced its own operational efforts by reducing water withdrawal by 34.4% from the 2019 baseline in 2025 and 4.9% compared to 2024.

Greenhouse Gas Emissions Reduction Target:

In 2025, Pentair achieved continued progress toward its Sustainability Strategic Target focused on GHG emissions reduction by reducing its Scope 1 and Scope 2 GHG emissions by 54.0% from its 2019 baseline.

Product Design for Sustainability:

In 2025, Pentair achieved the Sustainability Strategic Target, focused on sustainable product design, by assessing 100% of new products² with its product sustainability scorecard.³

"I am so proud of our progress and achievements in 2025 which has been supported and driven by Pentair employees around the world who are living our purpose of creating a better world for people and the planet through smart, sustainable water solutions," said Oriana Raabe, PhD., Vice President of Sustainability. "Our employees are at the heart of sustainability, taking actions every day that deliver for our customers, achieve progress toward our sustainability targets, and innovate for a more sustainable future."

The 2025 Sustainability Report also highlights examples of how Pentair's customer-focused, sustainable innovation efforts are delivering positive impacts for its customers, and for people and the planet, including:

Move Water:

23 million more people protected from flooding by Pentair pumps sold in 2025⁴
100,000 metric tons of carbon dioxide that can be recovered annually by customers using Pentair systems⁵

Improve Water:

40 billion single-use plastic water bottles avoided by customers using Pentair residential water filtration systems since 2021, equating to approximately 500,000 metric tons of plastic diverted from landfills⁶
18,000 gallons of water may be saved over the lifespan of the Manitowoc Indigo NXT ice machine with the new operating system, equivalent to nearly 230 bathtubs of water⁷

Enjoy Water:

80 percent of Pentair pool pumps and lights are energy efficient⁸
450,000 metric tons of CO2e emissions may be avoided by US consumers through our energy-efficient pool pumps, heaters, and lights sold in 2025⁹, equivalent to approximately 61,000 homes' energy use for one year¹⁰

¹"High-water-stress areas" are defined as areas that have an Overall Water Risk score of 3 or higher in the World Resource Institute's Aqueduct Water Risk Atlas tool. Water planned to be restored into the same or other high-water-stress areas as Pentair withdrawal.

²Physical products only.

³The product sustainability scorecard analyzed five impacts from a product's lifecycle - water use, energy use, GHG emissions, resource use efficiency, and material health - and incorporated an assessment of these impacts as part of new product design.

⁴Population estimates are derived from the latest available census data for the cities where pumps were sold. Actual population figures may differ based on the current 2025 population and the specific installation site of each pump following purchase.

⁵Based on 2025 sales of sustainable gas solutions.

⁶Based on cumulative sales of Pentair's brands meeting this definition from 2021-2025. Calculation based on a typical single-use plastic water bottle with 16.9 ounces of volume and containing 13.3 grams of polyethylene terephthalate.

⁷The updated Indigo NXT IYP0620A-261 may save up to 18,000 gallons of water over its lifespan compared to previous models. These potential water savings could be equivalent to nearly 230 bathtubs (assuming each bathtub holds 80 gallons). Savings are based on water usage data from publicly available manufacturer product specification sheets. Actual water consumption may vary.

⁸Based on 2025 products sold. Metric covers North American pool pumps and lights. Energy-efficient products are defined as pool pumps previously rated by ENERGY STAR® and LED lights.

⁹Based on total 2025 sales of ETi High-Efficiency Pool & Spa Heaters, pool pumps previously rated by ENERGY STAR, and LED lights made by Pentair. Savings calculated based on eight months of use.

¹⁰Emissions equivalency, calculated in March 2026, is estimated using the US Environmental Protection Agency's (EPA) GHG Equivalencies Calculator as available at that time.
