Information for Shareholders of Uponor in the United States

A voluntary public cash tender offer is being made by Georg Fischer Ltd. (the "Offeror") to acquire all issued and outstanding shares in Uponor Corporation (the "Uponor") (the "Shares") (the "Tender Offer"), which is domiciled in Finland, and is subject to Finnish disclosure and procedural requirements. The Tender Offer is made in the United States in compliance with Section 14(e) of the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act") and the applicable rules and regulations promulgated thereunder, including Regulation 14E (in each case subject to any exemptions or relief therefrom, if applicable) and otherwise in accordance with the disclosure and procedural requirements of Finnish law, including with respect to the Tender Offer timetable, settlement procedures, withdrawal, waiver of conditions and timing of payments, which are different from those of the United States. In particular, the financial information included in this presentation has been prepared in accordance with applicable accounting standards in Finland, which may not be comparable to the financial statements or financial information of U.S. companies. Shareholders in the United States are advised that the Shares are not listed on a U.S. securities exchange and that Uponor is not subject to the periodic reporting requirements of the Exchange Act, and is not required to, and does not, file any reports with the U.S. Securities and Exchange Commission (the "SEC") thereunder.

The Tender Offer is made to Uponor's shareholders resident in the United States on the same terms and conditions as those made to all other shareholders of Uponor to whom an offer is made. Any information documents are being disseminated to U.S. shareholders on a basis comparable to the method that such documents are provided to Uponor's other shareholders.

To the extent permissible under applicable law or regulations, including Rule 14e-5 under the Exchange Act, the Offeror and its affiliates or its brokers and its broker's affiliates (acting as agents for the Offeror or its affiliates, as applicable) may from time to time after the date hereof and during the pendency of the Tender Offer, and other than pursuant to the Tender Offer and combination, directly or indirectly, purchase or arrange to purchase the Shares or any securities that are convertible into, exchangeable for or exercisable for such Shares. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. To the extent information about such purchases or arrangements to purchase is made public in Finland, such information will be disclosed by means of a stock exchange or press release or other means reasonably calculated to inform U.S. shareholders of Uponor of such information. In addition, the financial advisers to the Offeror may also engage in ordinary course trading activities in securities of Uponor, which may include purchases or arrangements to purchase such securities. To the extent required in Finland, any information about such purchases will be made public in Finland in the manner required by Finnish law.
