Item 2.02. Results of Operations and Financial Condition

     On November 7, 2007, ION Geophysical Corporation (the “Company”) issued a press release containing information regarding the Company’s results of operations for the quarter ended September 30, 2007. A copy of the press release is furnished as Exhibit 99.1 hereto.

     The information contained in Item 2.02 and Exhibit 99.1 of this report (i) is not to be considered “filed” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and (ii) shall not be incorporated by reference into any previous or future filings made by or to be made by the Company with the Securities and Exchange Commission (“SEC”) under the Securities Act of 1933, as amended, or the Exchange Act.

     The information contained in this report and the attached exhibit contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements include statements concerning the expected impact of restating historical results of operations for certain accounting periods as described herein, estimated revenues, earnings and earnings per share for fiscal 2007, expected timing of revenues and growth rates in fiscal 2007, estimated gross margins and operating expenses for fiscal 2007, future sales and market growth, timing of product introduction and commercialization, and other statements that are not statements of historical fact. Actual results may vary materially from those described in these forward-looking statements. All forward-looking statements reflect numerous assumptions and involve a number of risks and uncertainties. These risks and uncertainties include audit adjustments and other modifications to the Company’s financial statements not currently foreseen, unanticipated delays in the timing and development of the Company’s products and services and market acceptance of the Company’s new and revised product offerings; risks associated with competitors’ product offerings and pricing pressures resulting therefrom; the relatively small number of customers that the Company currently relies upon; the fact that a significant portion of the Company’s revenues is derived from foreign sales; the risks that sources of capital may not prove adequate; the Company’s inability to produce products to preserve and increase market share; collection of receivables; and technological and marketplace changes affecting the Company’s product line. Additional risk factors, which could affect actual results, are disclosed by the Company from time to time in its filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December 31, 2006.
