Basis of Presentation and Responsibility for Interim Financial Statements

Basis of Presentation and Responsibility for Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements of Pentair plc and its subsidiaries (“we,” “us,” “our,” or “Pentair”) have been prepared following the requirements of the United States (“U.S.”) Securities and Exchange Commission for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (“GAAP”) can be condensed or omitted.

We are responsible for the unaudited condensed consolidated financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2025.

Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year.

Effective January 1, 2026, we reorganized the composition of our Flow and Water Solutions reportable segments to reflect how we are managing our business. As a result of this reorganization, our legacy residential and irrigation flow business moved from our Flow segment into our Water Solutions segment. The Pool segment remains unchanged. The applicable prior period amounts related to this change have been retrospectively reclassified to conform to the new composition. These changes have no impact on the Company’s historical consolidated financial performance or results of operations.

Our fiscal year ends on December 31. We report our interim quarterly periods on a calendar quarter basis.
