DEREGISTRATION OF UNSOLD SECURITIES

This Post-Effective Amendment No. 4 (the “Amendment”) on Form S-3 to the Registration Statement on Form S-4 (File No. 333-177895) (the “Registration Statement”) initially filed with the Securities and Exchange Commission by Kinder Morgan, Inc. (the “Company”) on November 10, 2011, is being filed to deregister certain unsold securities that were registered under the Registration Statement.

The Registration Statement registered 513,500,000 warrants to purchase Class P common stock of the Company (the “Warrants”) and 513,500,000 shares of Class P common stock of the Company (the “Common Shares”) issuable upon exercise of the Warrants. The Warrants expired at 5:00 p.m. ET on May 25, 2017 (the “Expiration Date”), and as a result, the Company has no further obligation to maintain the effectiveness of a registration statement with respect to the Warrants and Common Shares.

The Company is filing this Amendment to deregister the remaining 299,888,730 Warrants and 513,427,925 Common Shares.
