John L. Stauch, Pentair’s President and Chief Executive Officer commented, “We delivered another strong quarter of earnings growth driven by continued execution and agility from our businesses and functional teams across our balanced water portfolio, inclusive of Transformation initiatives and 80/20 actions. We stayed resilient and moved with speed during the first quarter to mitigate tariff impacts including implementing price increases, pre-buying inventory and capping orders to manage our supply chain. I am very grateful for how our teams continue to rise to the challenge and deliver for customers while creating value for shareholders. We have strong cash flow, a solid balance sheet and a balanced capital allocation strategy. We continue to help our customers move, improve and enjoy water, life’s most essential resource, while also working to enhance shareholder returns.”

We are ready to take additional actions should the tariff impact change. We are applying our prior inflationary learnings to manage our channel and maximize performance. We remain confident in our agility and ability to position our businesses to be successful in both the short-term and long-term and continue to deliver for all our stakeholders.”

The Company updated its estimated 2025 GAAP EPS from continuing operations to approximately $4.27 to $4.42, up approximately 14 percent to 18 percent compared to 2024, and maintained estimated EPS on an adjusted basis of approximately $4.65 to $4.80, up approximately 7 percent to 11 percent compared to 2024. The Company maintained its estimated full year 2025 sales of flat to up approximately 2 percent on a reported basis.

In addition, the Company introduces second quarter 2025 GAAP EPS from continuing operations guidance of approximately $1.24 to $1.28, up approximately 12 percent to 15 percent compared to the prior year period, and on an adjusted EPS basis of approximately $1.31 to $1.35, up approximately 7 percent to 11 percent compared to the prior year period.
