Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On January 6, 2010, Chart Industries, Inc. (the “Company”) posted a slide presentation on its investor relations website. Executive officers of the Company plan to make a presentation using these slides on January 6, 2010 at the Pritchard Capital Partners Energize 2010 Conference. A copy of these slides is furnished with this Current Report on Form 8-K as Exhibit 99.1. All information contained in the slides is furnished and shall not be deemed “filed” with the Securities and Exchange Commission for purposes of Section 18 of the Exchange Act, or otherwise be subject to the liability of that Section, and shall not be deemed to be incorporated by reference into any filing under the Securities Act or the Exchange Act, except to the extent the Company specifically incorporated it by reference.

The presentation furnished with this Current Report on Form 8-K as Exhibit 99.1 includes reference to earnings before interest, taxes, depreciation and amortization (“EBITDA”), a measure that is not recognized under generally accepted accounting principles (“GAAP”) and is referred to as a “non-GAAP financial measure.” A reconciliation of EBITDA to net income is set forth in the slide presentation attached as Exhibit 99.1. The Company encourages investors to review the reconciliation in conjunction with the use of EBITDA in the presentation. EBITDA is included in the presentation in order to provide additional information to investors as EBITDA is a basis upon which our management assesses financial performance. EBITDA or derivatives of EBITDA are also used by management to calculate compliance with certain covenants under the Company’s senior credit facility and the indenture governing its outstanding subordinated notes. While EBITDA is frequently used as a measure of operations and the ability to meet debt service requirements, it is not necessarily comparable to other similarly titled captions of other companies due to potential inconsistencies in the method of calculation.

The information set forth in Item 2.02 above is incorporated herein by reference.
