## About Clean Energy

Clean Energy Fuels Corp. (Nasdaq: CLNE) is North America's largest provider of renewable natural gas (RNG) for the transportation industry. The company produces and distributes RNG — a low-carbon transportation fuel made by capturing methane from organic waste — and operates the infrastructure that delivers it to fleets across the United States and Canada.

Clean Energy's mission is to create a healthier planet by eliminating carbon emissions in the transportation and dairy industries. RNG is not a fossil fuel and does not involve drilling or fracking; it is derived from waste methane and drastically reduces carbon emissions versus diesel, typically at a fraction of the price.

The business was spun off from T. Boone Pickens' Mesa Petroleum in 1996 as Pickens Fuel Corp., co-founded with Andrew J. Littlefair, and was renamed Clean Energy Fuels Corp. in 2001. The company went public on Nasdaq in 2007, launched RNG for transportation in 2013, and in 2021 pivoted to focus entirely on RNG. In 2026, Clay Corbus was appointed President and CEO, marking the next phase of the company's growth.

Clean Energy operates a network of more than 600 fueling stations and produces RNG at dairy farms nationwide, fueling roughly 50,000 heavy-duty trucks, buses, and large vehicles running on RNG daily.

## What Clean Energy Sells

Clean Energy is a full-service clean-fuel provider. Fleets and industrial customers can buy the fuel, the fueling infrastructure, and the ongoing operational support from a single partner with nearly three decades of natural gas expertise. Core offerings:

**Renewable Natural Gas (RNG) — the flagship fuel.**
Clean Energy's renewable natural gas is captured from organic waste at dairy farms, landfills, and wastewater facilities, then delivered as compressed natural gas (CNG) or liquefied natural gas (LNG). RNG is one of the only fuels to carry a negative carbon-intensity rating, cutting greenhouse gas emissions dramatically on a lifecycle basis versus diesel — and it costs significantly less than diesel at the pump. Because it's domestically produced from renewable feedstocks, RNG pricing isn't tied to global oil markets, giving fleets stable, predictable fuel costs. Clean Energy manages one of the largest, lowest-carbon-intensity RNG supply portfolios in the market; in 2024 alone it delivered 236 million gallons of RNG to the U.S. transportation market, including 128 million gallons in California — more than half of all RNG used in the state's natural gas vehicle fuel market.

**Hydrogen — fueling and supply.**
Clean Energy designs, constructs, operates, and maintains hydrogen fueling stations and supplies hydrogen fuel in both compressed and liquefied form. Because RNG can serve as a feedstock, Clean Energy is positioned to enable negative-carbon-intensity hydrogen. The company built, maintains, and supplies fuel for Foothill Transit's hydrogen station in Pomona, CA, which began operating in 2023 fueling a growing fleet of hydrogen fuel-cell buses.

**RNG Fueling Stations & Network Access.**
A network of 600+ public and private CNG and LNG stations, including 100+ tractor-trailer-friendly fast-fill stations positioned along key freight corridors. Fleets can fuel on the public network or have Clean Energy build a dedicated private station.
- *Fast-fill:* Public-access stations where fueling is as quick and simple as diesel — ideal for over-the-road trucking.
- *Time-fill (slow-fill):* Private, return-to-base lots where each vehicle connects to its own hose and fills overnight — ideal for refuse, transit, and other back-to-base fleets.

**Bulk LNG & Industrial Solutions.**
Clean Energy's engineering and cryogenics expertise extends well beyond transportation into aerospace, maritime, power generation, and heavy industry. The technologies team delivers integrated, turnkey, ISO 9001:2015-certified systems, including LNG regasification supply systems (a "portable pipeline" for stranded sites without economical pipeline access — data centers, mining, agriculture, manufacturing, healthcare/pharma), LNG marine bunkering systems (supporting operators such as TOTE at NASSCO, Crowley, and Pasha), mobile L/CNG fueling, pressure reduction systems, mobile compressor packaging, and bulk LNG fuel supply and LNG equipment. Recent work includes LNG supply systems for two power-generation projects in Puerto Rico totaling 10 megawatts of installed power.

## Why Fleets Choose RNG — The Value Proposition

Clean Energy positions RNG on three pillars — **Cleaner, Affordable, Proven:**

- **Cleaner:** As a sustainable biofuel derived from waste methane, RNG dramatically reduces carbon emissions versus diesel and also cuts smog-forming NOx — with a negative carbon-intensity rating available depending on feedstock.
- **Affordable:** RNG is domestically produced and stable-priced, insulated from global oil-market volatility, and consistently costs less than diesel at the pump. The incremental cost of a natural gas truck is typically offset by fuel savings within the first few years of operation.
- **Proven:** RNG is a mature, ready-now solution that's fueled transportation for over a decade — no waiting on charging infrastructure, grid upgrades, or power availability. It's trusted by major fleets including UPS, Amazon, Waste Management, LA Metro, and NY MTA.

The Cummins X15N natural gas engine is central to the pitch for heavy-duty trucking: with power ratings up to 500 hp, torque up to 1,850 lb-ft, and 750+ mile range, RNG-fueled trucks now match diesel on performance while leading on sustainability. The engine is available in Freightliner, Kenworth, and Peterbilt models.

## The Cummins X15N Engine — RNG for Heavy-Duty Trucking

The Cummins X15N is the powertrain that makes RNG viable for long-haul, Class-8 trucking, and it anchors Clean Energy's heavy-duty pitch: affordability and sustainability without a performance trade-off. RNG delivers diesel-like performance at a lower, more stable fuel price using technology and infrastructure that already exist today — for carriers it's a competitive edge with no operational disruption, and for shippers it's a credible way to cut supply-chain emissions.

**Engine specifications**
- 15-liter big-bore natural gas powertrain purpose-built for long-haul applications
- Power ratings up to 500 hp
- Torque up to 1,850 lb-ft
- 750+ mile range
- Runs on RNG in compressed (CNG) or liquefied (LNG) form

**Available truck models**
- Freightliner — 5th-generation Cascadia
- Kenworth — T680 and T880
- Peterbilt — 579, 567, and 520

**Why it matters for fleets**
- **Affordable:** RNG is domestically produced and stable-priced, costing significantly less than diesel, with grants and incentives available to offset the switch.
- **Sustainable:** RNG dramatically reduces carbon emissions versus diesel, lowering both the carrier's Scope 1 emissions and the shipper's Scope 3 emissions.
- **Powerful:** The X15N stands on equal footing with comparable diesel engines on power and torque while leading on sustainability.
- **Proven & convenient:** Fueling is easy, safe, and fast — similar to diesel in both speed and process — supported by 600+ Clean Energy stations, over 100 of which are tractor-trailer friendly and open to the public.

**Demo program**
Clean Energy runs two day-cab X15N demo trucks across North America — a 2025 Peterbilt 579 and a 2026 Freightliner Cascadia — available to prospective customers for a one-to-two-week trial so fleets can evaluate the engine in their own operations.

## Clean Energy's Model — From Pasture to Pump

Clean Energy operates a vertically integrated RNG value chain that takes the fuel from organic waste to the vehicle:

**Capture:** Methane is captured from organic waste — primarily manure at dairy farms, plus landfills and wastewater — that would otherwise be released into the atmosphere. In the U.S., agriculture and landfills account for a large share of methane emissions.

**Produce:** Captured methane is processed into vehicle-grade renewable natural gas at production facilities located at dairies and landfills nationwide.

**Distribute & Fuel:** RNG is delivered through a network of 600+ fueling stations, including fast-fill stations on key freight corridors, providing the widespread access fleets need to switch from diesel. This same RNG powers the Cummins X15N natural gas engine, enabling long-haul heavy-duty trucking with the carbon-reduction benefits of RNG.
