NEWS RELEASE for February 25, 2013

GENTHERM ANNOUNCES REGISTRATION OF DOMINATION AND PROFIT AND

LOSS TRANSFER AGREEMENT IN GERMANY

Gentherm Now Controls 98.8% of W.E.T. Shares

NORTHVILLE, MICHIGAN, U.S.A. AND ODELZHAUSEN, GERMANY (February 25, 2013) . . . Gentherm Incorporated (NASDAQ-GS: THRM), the global market leader and a developer of innovative thermal management technologies, today announced the registration of a Domination and Profit and Loss Transfer Agreement (DPLTA) with respect to its majority-owned subsidiary, W.E.T. Automotive Systems AG (W.E.T.). Registration of the DPLTA had been the subject of a lengthy legal dispute in Germany. The DPLTA essentially allows Gentherm and W.E.T. to be managed as one operational entity.

As previously announced, Gentherm recently acquired all of the shares of W.E.T. owned by the largest minority shareholder and the legal case opposing the registration of the DPLTA was simultaneously withdrawn. As a result of that transaction, Gentherm owned approximately 90 percent of W.E.T.’s outstanding shares.

Gentherm also announced today that it has since acquired or signed purchase agreements to acquire additional shares in W.E.T. from various minority shareholders that will increase Gentherm’s total ownership interest in W.E.T. to 98.8 percent of W.E.T.’s outstanding shares. The additional shares were purchased for €85 per share cash. Gentherm has agreed to offer to acquire, pursuant to the terms of the DPLTA, the remaining shares of W.E.T. held by the remaining minority shareholders for a payment of €85 per share.

President and CEO Daniel R. Coker said, “We are pleased to finally have this registration in place as we are excited to move ahead and complete the integration of these two companies. Together with the W.E.T. team, we are making substantial progress in building the global, innovative thermal business we envisioned when we embarked on this acquisition.”

Gentherm and W.E.T. will soon announce instructions in Germany for the remaining minority shareholders of W.E.T. who wish to deliver their W.E.T. shares to Gentherm in exchange for payment of €85 per W.E.T. share.
