Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our ordinary shares are listed for trading on the New York Stock Exchange (“NYSE”) under the symbol “PNR.” As of December 31, 2025, there were 11,149 shareholders of record.

Pentair has paid 200 consecutive quarterly cash dividends, including most recently a dividend of $0.25 per share in the fourth quarter of 2025. On December 15, 2025, Pentair’s Board of Directors approved a regular quarterly cash dividend of $0.27 per share that was paid on February 6, 2026 to shareholders of record at the close of business on January 23, 2026. This dividend reflects an 8 percent increase in the Company’s regular cash dividend rate and marks the 50th consecutive year that Pentair has increased its dividend.

The timing, declaration and payment of future dividends to holders of our ordinary shares will depend upon many factors, including our financial condition and results of operations, the capital requirements of our businesses, industry practice and any other relevant factors.

Share Performance Graph

The following information under the caption “Share Performance Graph” in this ITEM 5 of this Annual Report on Form 10-K is not deemed to be “soliciting material” or to be “filed” with the SEC or subject to Regulation 14A or 14C under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or to the liabilities of Section 18 of the Exchange Act and will not be deemed to be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent we specifically incorporate it by reference into such a filing.

The following graph sets forth the cumulative total shareholder return on our ordinary shares for the last five years, assuming the investment of $100 on December 31, 2020 and the reinvestment of all dividends since that date to December 31, 2025. The graph also contains for comparison purposes the S&P 500 Index and the S&P 500 Industrials Index, assuming the same investment level and reinvestment of dividends.

By virtue of our market capitalization, we are a component of the S&P 500 Index. On the basis of our size and diversity of businesses, we believe the S&P 500 Industrials Index is an appropriate published industry index for comparison purposes.
