Item 3.03.     Material Modification to Rights of Security Holders.

        As previously reported on the Form 8-K of Badger Meter, Inc. (the “Company”) filed with the Securities and Exchange Commission on May 1, 2006, the Company’s Board of Directors approved a 2-for-1 stock split in the form of a 100% stock dividend (the “Stock Split”) on the Company’s common stock, par value $1 per share (the “Common Stock”), to shareholders of record June 1, 2006, payable June 15, 2006 (the “Split Date”).

        The Company is a party to that certain Rights Agreement, dated as of May 26, 1998, as amended (the “Rights Agreement”), between the Company and American Stock Transfer & Trust Company (“ASTT”), as successor to U.S. Bank, National Association (f/k/a Firstar Bank, N.A., successor to Firstar Trust Company). Pursuant to the Rights Agreement, a common share purchase right (each a “Right”) is associated with each outstanding share of Common Stock, and each share of Common Stock issued in connection with the Stock Split is accompanied by a Right. Prior to the Split Date, upon the occurrence of certain events, each Right entitled the registered holder to purchase from the Company one share of Common Stock at a Purchase Price (as defined in Section 7(b) of the Rights Agreement) of $70.00 per share of Common Stock. In connection with the Stock Split, effective as of the Split Date, (1) pursuant to Section 11 of the Rights Agreement, the Purchase Price is reduced from $70.00 to $35.00; and (2) pursuant to Section 23 of the Rights Agreement, the Redemption Price (as defined in Section 23(b) of the Rights Agreement) for each Right that may be redeemed pursuant to Section 23 of the Rights Agreement is reduced from $0.005 to $0.0025.

        A copy of the Certificate of Adjustment that was sent to the Rights Agent (as defined in the Rights Agreement) and to the Company’s transfer agent is attached to this Current Report on Form 8-K as Exhibit 4.1 and is incorporated by reference in this Current Report on Form 8-K.

        The Rights Agreement was filed as Exhibit 4.1 to the Company’s Registration Statement on Form 8-A filed with the Securities and Exchange Commission on May 26, 1998. Subsequently, the Company filed an Agreement of Substitution and Amendment of Common Shares Rights Agreement, dated August 16, 2002 (the “Amendment”), between the Company and ASTT, naming ASTT as the successor Rights Agent to U.S. Bank, National Association. The Amendment was filed as Exhibit 4.2 to the Company’s Registration Statement on Form S-3 (Registration No. 333-102057) filed with the Securities and Exchange Commission on December 20, 2002. Reference is made to the Rights Agreement for a more complete description of the terms of the Rights.
