EXPLANATORY NOTE

Effective as of May 16, 2013, Gentherm Incorporated, a Michigan corporation (the “Registrant”) adopted the Gentherm Incorporated 2013 Equity Incentive Plan (the “2013 Plan”). The 2013 Plan permits the issuance of, among other things, a maximum of (i) 2,307,000 shares of the Registrant’s common stock, no par value (the “Common Stock”) that were previously reserved for issuance but never awarded (the “Unused Shares”) under the Gentherm Incorporated 2011 Equity Incentive Plan, f/k/a the Amerigon Incorporated 2006 Equity Incentive Plan (the “2011 Plan”), and (ii) an indeterminate number of shares Common Stock that were subject to awards under the 2011 Plan that expire, are terminated, surrendered or cancelled without the delivery of Common Stock in the case of stock options or are forfeited or reacquired by the Company in accordance with the terms of the 2011 Plan in the case of unvested restricted stock awards (the “Outstanding Shares”). The Unused Shares and the Outstanding Shares were previously registered on the Registrant’s Registration Statement on Form S-8 (Commission File No. No. 333-181975), which was originally filed on June 7, 2012 (the “2012 Registration Statement”). Accordingly, the purpose of this Post-Effective Amendment No. 1 to the 2012 Registration Statement is to permit the Registrant to issue the Common Stock registered thereunder in accordance with the terms of the 2013 Plan as well. As a result, the 2012 Registration Statement now covers Common Stock issuable under both the 2011 Plan and the 2013 Plan.

Except to the extent specified above, the 2012 Registration Statement as previously filed is not amended or otherwise affected by this Post-Effective Amendment No. 1 thereto.
