CLEAN ENERGY FUELS INCREASES VOLUMES SOLD AND ADJUSTED EBITDA IN THE THIRD QUARTER OF 2009

· Gallons Sold Increases 58% Over Prior-Year Period To 29.5 Million Gallons

· Adjusted EBITDA Increases $6.4 Million over Prior-Year Period

Seal Beach, Calif. — November 9, 2009 — Clean Energy Fuels Corp. (NASDAQ: CLNE) today announced its operating results for the third quarter and nine months ended September 30, 2009.

Gasoline gallon equivalents (Gallons) delivered during the third quarter of 2009 totaled 29.5 million, up 58% from 18.7 million Gallons in the same period a year ago. For the first nine months of 2009, volume increased 30% to 71.5 million Gallons, compared with 54.8 million Gallons in the first nine months of 2008. Gallons include the Company’s sales of CNG, LNG, and biomethane and the Gallons associated with providing operations and maintenance services.

Adjusted EBITDA for the third quarter of 2009 was $5.4 million, compared to a loss of $1.0 million in the third quarter of 2008. Adjusted EBITDA for the first nine months of 2009 was $9.9 million, compared with a loss of $7.0 million in the first nine months of 2008. Adjusted EBITDA is described below and reconciled to the GAAP measure net income (loss) attributable to Clean Energy.

Non-GAAP earnings per share for the third quarter of 2009 was $0.01, compared to a non-GAAP loss per share of $0.08 in the third quarter of 2008. Non-GAAP loss per share for the first nine months of 2009 was $0.06, compared with $0.28 in the first nine months of 2008. Non-GAAP EPS (or Non-GAAP earnings/loss per share) is described below and reconciled to the GAAP measure net income (loss) attributable to Clean Energy.

Net loss for the third quarter of 2009 was $18.5 million, or $0.31 per share, compared with a net loss of $12.1 million, or $0.27 per share, in the third quarter of 2008. For the first nine months of 2009, net loss was $31.3 million, or $0.59 per share, compared to a net loss of $20.7 million, or $0.47 per share, in the first nine months of 2008. During the third quarter of 2009, the Company recorded a non-cash charge of $15.4 million (or $0.26 per share) related to marking to market the value of its Series I warrants, which is required this year under new accounting guidance. The primary driver of the increased amount recorded this quarter was the impact of the Company’s higher stock price on the valuation model used to value the warrants.

Revenue for the quarter ended September 30, 2009 totaled $31.2 million, compared with $33.8 million in the same period in 2008. For the nine months ended September 30, 2009, revenue totaled $89.3 million, compared with $97.6 million a year ago. The reduction in revenue was primarily the result of lower natural gas commodity prices between periods, which reduced the natural gas commodity charges passed through by the Company to many of its customers. The reduced commodity prices, however, also reduce the Company’s cost of sales, which enabled the Company to generate a gross margin in the third quarter of 2009 that was $0.7 million higher than the second quarter of 2009.

Andrew J. Littlefair, Clean Energy’s President and Chief Executive Officer, stated, “We are pleased with our third quarter performance as we are benefitting from positive developments on several fronts in our business. We experienced strong volume growth in the quarter, reflecting solid progress on the clean truck roll-out at the ports of Los Angeles and Long Beach, as well as our growing station count and the addition of several new customers. As the economic and environmental benefits of natural gas are becoming more widely understood and well publicized, we have expanded our discussions to include a number of large fleet operators and corporations regarding the conversion of their fleets to natural gas.”

Mr. Littlefair continued, “On the strategic front, we recently announced our acquisition of BAF Technologies, Inc., a leading provider of natural gas vehicle conversions, which will enable us to leverage our industry expertise and help bring natural gas vehicles to the light-duty market. The NAT GAS Act also continues to garner strong bi-partisan support and we remain optimistic that this will be passed in the near future. We are very confident with our industry’s momentum and our own positioning as we enter the final quarter of 2009 and look forward to 2010.”

Non-GAAP Financial Measures

To supplement the Company’s consolidated financial statements, which statements are prepared and presented in accordance with GAAP, the Company uses non-GAAP financial measures called non-GAAP earnings per share (non-GAAP EPS or non-GAAP earnings/loss per share) and Adjusted EBITDA. This is the first quarter in which the Company has presented the Adjusted EBITDA financial measure described herein. The Company’s management uses these non-GAAP financial measures to assess our operational performance, for financial and operational decision making, and as a means to evaluate period-to-period comparisons on a consistent basis. Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding the Company’s performance by excluding certain non-cash expenses that are not directly attributable to its core operating results. In addition, management believes these non-GAAP financial measures are useful to investors because: (1) they allow for greater

transparency with respect to key metrics used by management in its financial and operational decision making; (2) they exclude the impact of non-cash items that are not directly attributable to the Company’s core operating performance and that may obscure trends in the core operating performance of our business; and (3) they are used by institutional investors and the analyst community to help them analyze the results of Clean Energy’s business. While the Company has not done so for the periods presented in this release, in future quarters, the Company may make adjustments for additional non-recurring significant expenditures or other significant non-cash charges in order to present non-GAAP financial measures that are indicative of the Company’s core operating performance.

Non-GAAP financial measures have limitations as an analytical tool and should not be considered in isolation from or as a substitute for the Company’s GAAP results. In the future, the Company expects to continue reporting non-GAAP financial measures, adjusting for the items described below, and the Company expects to continue to incur expenses similar to the non-GAAP adjustments described below. Accordingly, exclusion of these and other similar items in the presentation of non-GAAP financial measures should not be construed as an inference that these costs are unusual, infrequent or non-recurring. Non-GAAP EPS and Adjusted EBITDA are not recognized terms under GAAP and do not purport to be an alternative to GAAP earnings/loss per share or operating loss as an indicator of operating performance or any other GAAP measure. Moreover, because not all companies use identical measures and calculations, the presentation of non-GAAP EPS or Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. These limitations are compensated for by using non-GAAP EPS and Adjusted EBITDA in conjunction with traditional GAAP operating performance and cash flow measures.

Non-GAAP EPS

Non-GAAP EPS is defined as net income (loss), plus employee-related stock based compensation charges, net of related tax benefits, plus or minus futures contracts losses or gains included in derivative (gains) losses, plus or minus any mark-to-market losses or gains on the Company’s Series I warrants, the total of which is divided by the Company’s weighted average shares outstanding on a diluted basis. The Company’s management believes that presenting non-GAAP EPS, excluding non-cash charges related to stock-based compensation, provides useful information to investors because of varying available valuation methodologies, the volatility of the expense (which depends on market forces outside of management’s control), the subjectivity of the assumptions and the variety of award types that a company can use under the accounting guidance may obscure trends in the Company’s core operating performance. Similarly, the Company’s management believes that excluding the non-cash, mark-to-market losses or gains on the Company’s Series I warrants is useful to investors because the Company has not reported such losses or gains in past periods, the valuation of the Series I warrants is subject to a number of subjective assumptions, and the amount of the loss or gain is derived from market forces outside of management’s control.

Adjusted EBITDA

Adjusted EBITDA is defined as net income (loss) attributable to Clean Energy, plus or minus income tax expense or benefit, plus or minus interest expense or income, net, plus depreciation and amortization expense, plus employee-related stock based compensation charges, net of related tax benefits, plus or minus futures contracts losses or gains included in derivative (gains) losses, plus or minus any mark-to-market losses or gains on the Company’s Series I warrants. Management internally uses Adjusted EBITDA to monitor compliance with certain financial covenants in the Company’s credit agreement with PlainsCapital Bank and to determine elements of executive and employee compensation.
