KIOR REPORTS THIRD QUARTER 2013 RESULTS

Columbus Transitioning to Steady State

BFCC on Record Run

Cornerstone Financial Commitments for Columbus II

PASADENA, Texas, November 7, 2013—KiOR, Inc. (NASDAQ: KiOR), announced today its financial results for the third quarter ended September 30, 2013.

“I am happy to report again that we are seeing significant operational progress at our Columbus facility and we believe that we are turning the corner toward steady state operations,” said Fred Cannon, KiOR’s President and Chief Executive Officer. “We produced 323,841 gallons of fuel in the quarter, which brought us to a total production of 508,975 gallons of cellulosic fuel through the end of the third quarter.”

“Just as importantly,” Cannon continued, “Columbus is on a run which began in mid-September, and we are continuing to ramp up throughput at the facility. Our fourth quarter has gotten off to a good start and we saw total production in October of 167,087 gallons of fuel, our highest month to date. As a result, we believe that with stable production over the balance of the year, our full year production levels will exceed 1 million gallons. These achievements support our strategy to pursue Columbus II as the company’s next project and the $100 million in financing commitments we received are serving as the cornerstone investments for that facility.”

Financial Results

For the third quarter 2013 the company recorded a net loss of $43.1 million, or $0.40 per share, compared to a net loss of $38.5 million, or $0.36 per share, for the second quarter of 2013. The third quarter loss included an unfavorable adjustment of $2.1 million for higher than expected franchise taxes primarily related to prior periods. Net loss for the third quarter of 2012 totaled $27.0 million, or $0.26 per share.

During the third quarter of 2013 total revenues were $720 thousand, attributable to higher sales volume produced from our initial-scale commercial production facility in Columbus, Mississippi. Total revenues for the second quarter of 2013 were $239 thousand compared to none in the third quarter of 2012.

Cost of product revenue for the third quarter of 2013 totaled $19.5 million, which includes non-cash charges of $2.2 million for the Columbus plant depreciation as well as the aforementioned $2.1 million accrual for franchise taxes. Cash costs totaled $15.2 million and consist primarily of feedstock and consumables, labor, utilities, repairs and maintenance and associated start-up costs incurred in connection with our efforts to achieve steady-state plant operations. In the previous quarter and the third quarter of last year, cost of product revenue was $15.1 million and zero, respectively.

Research and development expenses for the third quarter 2013 were $7.9 million, a decrease of $0.7 million from the $8.6 million incurred in the second quarter of 2013, and a decrease of $1.6 million from the $9.5 million recorded for the third quarter of 2012. These favorable variances to prior quarter and year-over-year reflect primarily lower lab costs and maintenance costs at our Pasadena demo and pilot plants.

General and administrative expenses for the third quarter of 2013 were $7.3 million compared to $7.9 million in the previous quarter and to the $17.5 million recorded for the third quarter of 2012. The quarter-over-quarter decrease reflects lower consulting and employment related expenses. In comparison to the third quarter of 2012, the large reduction is due to start-up related activities at the Columbus plant being previously recorded to general and administrative expense prior to commencement of commercial operations in March 2013. All Columbus production costs as well as costs to get to steady state operations are now included and reported in cost of product revenue.

Cash and cash equivalents at September 30, 2013, totaled $4.3 million compared to $11.5 million at the end of the second quarter 2013. The $50 million of cash received from our two recent private placements were not received until after quarter-end and are not reflected in the above cash balances.

Net long-term debt at the end of the third quarter of 2013 was $175.7 million compared to $149.7 million in the previous quarter, with the increase attributable to additional draws made under the company’s loan facility during the quarter and interest paid-in-kind during the period. Capital investments during the third quarter were $1.1 million, primarily related to front end engineering and design work related to KiOR’s planned Columbus II production facility.
