Commentary by Andrew J. Littlefair, President and Chief Executive Officer

“Hats off to the Clean Energy team for finishing the year strong with a 9% year over year increase in quarterly RNG delivered and ending 2024 at the low end of our GAAP loss guidance range and exceeding the high end of our Adjusted EBITDA guidance range, leaving us on strong financial footing. Our growing fuel volumes of RNG are contributing positively to our favorable financial results even before the anticipated impact of the additional volumes driven by trucks hitting the road with the new Cummins X15N engine, which should occur later in 2025 and beyond. And we’ve already begun to work with the new Administration as it focuses on solutions rather than mandates when it comes to transportation energy needs. Because of its environmental and economic development benefits to both urban and rural areas, RNG already has broad bipartisan support and should be part of every discussion regarding the heavy-duty transportation sector across the US and Canada.”

Summary and Review of Results

The Company’s revenue for the fourth quarter of 2024 was reduced by $18.0 million of non-cash stock-based sales incentive contra-revenue charges (“Amazon warrant charges”) related to the warrant issued to Amazon.com NV Investment Holdings LLC (the “Amazon warrant”), compared to Amazon warrant charges of $16.1 million in Q4 2023. Q4 2024 includes $6.1 million of AFTC revenue versus $5.9 million of AFTC in Q4 2023. Q4 2024 station construction revenues of $6.1 million versus $8.9 million of station construction revenues in Q4 2023. Revenue for Q4 2024 also included an unrealized loss of $0.4 million on commodity swap and customer fueling contracts relating to the Company’s Zero Now truck financing program, compared to an unrealized loss of $1.7 million in Q4 2023. Q4 2023 also included an unrealized gain from commodity swaps of $1.8 million related to the Zero Now truck financing program.  Q4 2024 renewable identification number (“RIN”) and low carbon fuel standards (“LCFS”) revenues of $13.5 million versus $11.5 million of RIN and LCFS revenues in Q4 2023 reflecting principally an increase in gallons of RNG fuel sold, increased mix of low carbon intensity dairy RNG, increased share of RIN values and higher LCFS prices partially offset by lower RIN credit prices in Q4 2024 versus 2023.

Net loss attributable to Clean Energy for Q4 2024 included an impairment of investments in equity securities of $8.1 million versus no such charge in Q4 2023 and Q4 2024 had higher Amazon warrant charges when compared to Q4 2023. Q4 2024 non-operating net interest expenses were lower than Q4 2023 primarily due to debt extinguishment expense in Q4 2023. Q4 2024 losses from equity method investments were higher than Q4 2023 due to the ramp up of operations of our dairy RNG projects in 2024. Selling, general and administrative expenses were higher in Q4 2024 compared to Q4 2023 by approximately $3.8 million mainly due to higher wages and salaries expense and business insurance costs, partially offset by lower stock compensation expense in Q4 2024.

Non-GAAP income (loss) per share (as defined below) for Q4 2024 was $0.02, compared to $0.01 per share for Q4 2023.

Adjusted EBITDA was $23.6 million for Q4 2024, compared to $21.2 million for Q4 2023.

In this press release, Clean Energy refers to various GAAP (U.S. generally accepted accounting principles) and non-GAAP financial measures. The non-GAAP financial measures may not be comparable to similarly titled measures being used and disclosed by other companies. Clean Energy believes that this non-GAAP information is useful to an understanding of its operating results and the ongoing performance of its business. Non-GAAP income (loss) per share and Adjusted EBITDA are defined below and reconciled to GAAP net income (loss) per share attributable to Clean Energy and GAAP net income (loss) attributable to Clean Energy, respectively.

The table below shows GAAP and non-GAAP income (loss) attributable to Clean Energy per share and also reconciles GAAP net income (loss) attributable to Clean Energy to the non-GAAP net income (loss) attributable to Clean Energy figure used in the calculation of non-GAAP income (loss) per share:

Fuel and Service Volume

The following tables present, for the three months and year ended December 31, 2023 and 2024, (1) the amount of total fuel volume the Company sold to customers with particular focus on RNG volume as a subset of total fuel volume and (2) operation and maintenance (“O&M”) services volume dispensed at facilities the Company does not own but at which it provides O&M services on a per-gallon or fixed fee basis. Certain gallons are included in both fuel and service volumes when the Company sells fuel (product revenue) to a customer and provides maintenance services (service revenue) to the same customer.

(1) The Company calculates one gasoline gallon equivalent (“GGE”) to equal 125,000 British Thermal Units (“BTUs”), and, as such, one million BTUs (“MMBTU”) equal eight GGEs.

Sources of Revenue

The following table shows the Company’s sources of revenue for the three months and year ended December 31, 2023 and 2024:

Three Months Ended Year Ended

Total service revenue 13.7 14.9 55.3 59.2
Total revenue $ 106.9 $ 109.3 $ 425.2 $ 415.9

(1) The Company’s volume-related product revenue primarily consists of sales of RNG and conventional natural gas, in the form of CNG and LNG, and sales of RINs and LCFS Credits in addition to changes in fair value of our derivative instruments.

(2) Includes $16.1 million and $60.6 million of Amazon warrant non-cash stock-based sales incentive contra-revenue charges for the three months and year ended December 31, 2023, respectively. Includes $18.0 million and $60.8 million of Amazon warrant non-cash stock-based sales incentive contra-revenue charges for the three months and year ended December 31, 2024, respectively.

(3) The change in fair value of unsettled derivative instruments is related to the Company’s commodity swap and customer fueling contracts. The amounts are classified as revenue because the Company’s commodity swap contracts are used to economically offset the risk associated with the diesel-to-natural gas price spread resulting from customer fueling contracts under the Company’s truck financing program.

4

(4) Includes net settlement of the Company’s commodity swap derivative instruments. For the three months and year ended December 31, 2023, net settlement payments recognized in fuel revenue were $1.9 million and $4.9 million, respectively. For the three months and year ended December 31, 2024, net settlement payments recognized in fuel revenue were $0.0 million and $2.4 million, respectively.

2025 Outlook

Our GAAP net loss for 2025 is expected to range from approximately $(160) million to $(155) million, assuming no unrealized gains or losses on customer contracts relating to the Company’s truck financing program and including Amazon warrant charges estimated to be approximately $53 million, and up to approximately $55 million in accelerated depreciation expense from the potential abandonment of certain LNG station assets located at 55 Pilot Flying J locations. Changes in diesel and natural gas market conditions resulting in unrealized gains or losses on the Company’s customer fueling contracts relating to the Company’s truck financing program, and significant variations in the vesting of the Amazon warrant could significantly affect the Company’s estimated GAAP net loss for 2025. Adjusted EBITDA for 2025 is estimated to range from approximately $50 million to $55 million. These expectations exclude the impact of any acquisitions, divestitures, new joint ventures, transactions and other extraordinary events; and macroeconomic conditions and global supply chain issues. Additionally, the expectations regarding 2025 Adjusted EBITDA assume the calculation of this non-GAAP financial measure in the same manner as described above and adding back the estimated Amazon warrant charges described above and without adjustments for any other items that may arise during 2025 that management deems appropriate to exclude. These expectations are forward-looking statements and are qualified by the statement under “Safe Harbor Statement” below.

Non-GAAP Financial Measures

To supplement the Company’s unaudited consolidated financial statements presented in accordance with GAAP, the Company uses non-GAAP financial measures that it calls non-GAAP income (loss) per share (“non-GAAP income (loss) per share”) and adjusted EBITDA (“Adjusted EBITDA”). Management presents non-GAAP income (loss) per share and Adjusted EBITDA because it believes these measures provide meaningful supplemental information about the Company’s performance for the following reasons: (1) they allow for greater transparency with respect to key metrics used by management to assess the Company’s operating performance and make financial and operational decisions; (2) they exclude the effect of items that management believes are not directly attributable to the Company’s core operating performance and may obscure trends in the business; and (3) they are used by institutional investors and the analyst community to help analyze the Company’s business. In future quarters, the Company may adjust for other expenditures, charges or gains to present non-GAAP financial measures that the Company’s management believes are indicative of the Company’s core operating performance.

Non-GAAP financial measures are limited as an analytical tool and should not be considered in isolation from, or as a substitute for, the Company’s GAAP results. The Company expects to continue reporting non-GAAP financial measures, adjusting for the items described below (and/or other items that may arise in the future as the Company’s management deems appropriate), and the Company expects to continue to incur expenses, charges or gains like the non-GAAP adjustments described below. Accordingly, unless expressly stated otherwise, the 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 income (loss) per share and Adjusted EBITDA are not recognized terms under GAAP and do not purport to be an alternative to GAAP income (loss), GAAP income (loss) per share or any other GAAP measure as an indicator of operating performance. Moreover, because not all companies use identical measures and calculations, the Company’s presentation of non-GAAP income (loss) per share and Adjusted EBITDA may not be comparable to other similarly titled measures used by other companies.

Non-GAAP Income (Loss) Per Share

Non-GAAP income (loss) per share, which the Company presents as a non-GAAP measure of its performance, is defined as net income (loss) attributable to Clean Energy Fuels Corp., plus Amazon warrant charges, plus stock-based compensation expense, plus (minus) loss (income) from Rimere equity method investment, plus (minus) loss (income) from the SAFE&CEC S.r.l. equity method investment, plus (minus) any loss (gain) from changes in the fair value of derivative instruments, and minus amortization of investment tax credit from RNG equity method investments, the total of which is divided by the Company’s weighted-average common shares outstanding on a diluted basis. The Company’s management believes excluding non-cash expenses related to the Amazon warrant charges provides useful information to investors regarding the Company’s performance because the Amazon warrant charges are measured based upon a fair value determined using a variety of assumptions and estimates, and the Amazon warrant charges do not affect the Company’s operating cash flows related to the delivery and sale of vehicle fuel to its customer. The Company’s management believes excluding non-cash expenses related to stock-based compensation provides useful information to investors regarding the Company’s performance because of the 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, which may obscure 6

trends in a company’s core operating performance. In addition, the Company’s management believes excluding the results from the Rimere equity method investment is useful to investors because Rimere is an investment belonging to the non-core operations of the Company, and its results are not indicative of the Company’s ongoing operations. Similarly, the Company’s management believes excluding the non-cash results from the SAFE&CEC S.r.l. equity method investment is useful to investors because these charges are not part of or representative of the core operations of the Company. In addition, the Company’s management believes excluding the non-cash loss (gain) from changes in the fair value of derivative instruments is useful to investors because the valuation of the derivative instruments is based on a number of subjective assumptions, the amount of the loss or gain is derived from market forces outside of management’s control, and the exclusion of these amounts enables investors to compare the Company’s performance with other companies that do not use, or use different forms of, derivative instruments. Furthermore, the Company’s management believes excluding other income relating to the amortization of investment tax credit from RNG equity method investments is useful to investors because such income is not generated from the core operations of the Company and may obscure trends of the Company’s core operations.

Adjusted EBITDA

Adjusted EBITDA, which the Company presents as a non-GAAP measure of its performance, is defined as net income (loss) attributable to Clean Energy Fuels Corp., plus (minus) income tax expense (benefit), plus interest expense (including any losses from the extinguishment of debt), minus interest income, plus depreciation and amortization expense, plus Amazon warrant charges, plus stock-based compensation expense, plus (minus) loss (income) from the Rimere equity method investment, plus (minus) loss (income) from the SAFE&CEC S.r.l. equity method investment, plus (minus) any loss (gain) from changes in the fair value of derivative instruments, plus depreciation and amortization expense from RNG equity method investments, plus interest expense from RNG equity method investments, minus interest income from RNG equity method investments, and minus amortization of investment tax credit from RNG equity method investments. The Company’s management believes Adjusted EBITDA provides useful information to investors regarding the Company’s performance for the same reasons discussed above with respect to non-GAAP income (loss) per share. In addition, management internally uses Adjusted EBITDA to determine elements of executive and employee compensation.
