Pentair Board of Directors Approves Proposed Change in Place of Incorporation

SCHAFFHAUSEN, Switzerland - December 10, 2013 - Pentair Ltd. (NYSE: PNR) (“Pentair”) announced today its Board of Directors has approved changing the place of incorporation of the publicly-traded parent company of Pentair from Switzerland to Ireland. Pentair’s shareholders will be asked to vote to approve the proposed change of place of incorporation at an anticipated second quarter 2014 shareholder meeting.

Pending shareholder approval, Pentair expects the change of incorporation location to be effective as soon as practicable following the merger of Pentair, the current Swiss publicly-traded parent company, into a newly-formed Irish company named Pentair plc. Pentair plc will then become the publicly-traded parent company of Pentair and its subsidiaries with its tax residency in the U.K.

“After careful review and consideration, our desire to redomicile is based on our commitment to shareholder value creation,” said Randall J. Hogan, Pentair Chairman and Chief Executive Officer. “We believe the well-developed legal and regulatory system and established standards of corporate governance in Ireland provides us with advantages as a publicly traded NYSE company. Coupled with the stable and internationally competitive tax system in the U.K., we believe it will help us maintain our competitive position in the global marketplace.”

The company also stated that it remains committed to its long term growth strategy, its target synergies from the transaction, and its $5 per share 2015 EPS goal.

Upon completion of the transaction, holders of Pentair shares will receive one Pentair plc ordinary share for each Pentair share. Pentair plc will continue to be subject to U.S. Securities and Exchange Commission (“SEC”) reporting requirements, and its ordinary shares will be listed solely on the New York Stock Exchange under the symbol “PNR,” Pentair’s current trading symbol.

Full details of the change in place of incorporation, including the merger and associated benefits and risks, will be contained in a proxy statement/prospectus with respect to the extraordinary general meeting of shareholders that will be filed with the SEC. Completion of the merger will be subject to various conditions described in the proxy statement/prospectus.
