PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

KiOR, Inc. (the “Company”) has determined that it is unable to file its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2014 (“Form 10-Q”) in a timely manner and it does not expect to be able to file the Form 10-Q within the five-day extension permitted by the rules of the United States Securities and Exchange Commission (the “SEC”). As previously disclosed in the Company’s Form 8-K filed with the SEC on November 10, 2014, the Company filed a voluntary petition in the United States Bankruptcy Court for the District of Delaware seeking relief under the provisions of Chapter 11 of the United States Bankruptcy Code (Case No. 14-12514) (the “Bankruptcy Case”). The Bankruptcy Case comes after a severe reduction in the Company’s workforce and the Company has devoted substantially all of its remaining resources to the Bankruptcy Case, including a substantial portion of its accounting and financial reporting personnel and administrative resources. As a result, the Company has determined that it is unable to file its Form 10-Q without unreasonable effort and expense.

PART IV — OTHER INFORMATION

(1)  Name and telephone number of person to contact in regard to this notification

Christopher A. Artzer	(281)	694-8700
(Name)	(Area Code)	(Telephone Number)

(2)  Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).    x  Yes    ¨  No

(3)  Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?    x  Yes    ¨  No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

Due to adverse business conditions, the inability to restructure the Company’s outstanding debt, the commencement of the Bankruptcy Case and other circumstances, there was a significant adverse change in the Company’s results of operations for its fiscal quarter ended September 30, 2014 compared with the Company’s results of operations for its fiscal quarter ended September 30, 2013. As a result of management’s preparation of the bankruptcy filing and the demands the Bankruptcy Case has placed on the Company’s available personnel and limited resources, the Company cannot provide quantitative estimates of the results of operations for the quarterly period ended September 30, 2014.
