Clean Energy Keeps Its $70M-$75M Target as 45Z Adds an Upside Tip Toward $80M

Clean Energy's base case still looks supportable

Clean Energy reaffirmed its full-year adjusted EBITDA guidance of $70 million to $75 million, and second-quarter results were broadly in line with that outlook: revenue reached $106.4 million, adjusted EBITDA was $16 million, and fuel volumes rose 7% year over year to 81.8 million gallons. That does not guarantee the full-year target will hold, but it does show operating momentum behind the range rather than only a policy narrative.

The next near-term catalyst is Treasury's final guidance for section 45Z. Management has already said that guidance could affect 2026 EBITDA, and investors are focused on whether the rule simply validates the current range or adds to it. The market uptalk around that upside is roughly $5 million, which is modest in dollar terms but meaningful for sentiment.

What helps the $70M-$75M target hold

The base case looks more credible because Clean Energy already has scale. The company says it operates 600+ fueling stations across North America and that more than 50,000 heavy-duty trucks, buses, and other large vehicles fuel through its network each day. That footprint does not ensure the target will be beaten, but it does help support the argument that the business is already scaling.

RNG supply is the part that still needs to ramp

Management also said dairy RNG production improved significantly, and upstream performance will likely matter more in the second half of the year. If those projects continue to ramp, Clean Energy may have a better chance of defending its annual EBITDA range even if demand improves only gradually.

Demand looks incremental, not all-or-nothing

The company described truck adoption of RNG remains gradual, but said diesel costs and fleet interest are still helping demand. It is also broadening the story beyond vehicle fueling through CNG power-generation and industrial contracts, while a $27 million hydrogen fueling-station contract with the Orange County Transportation Authority shows there is still customer appetite for niche infrastructure.

OPAL expansion shows the market is growing, not shrinking

OPAL says new projects are expected to add approximately 15 million GGEs of RNG supply capacity. That supports the view that the market is expanding. At the same time, more supply can increase competition, so Clean Energy still needs to convert its network into stronger RNG volumes and margins.

Why the $5M 45Z upside matters more as a signal than a number

Section 45Z is a clean fuel production tax credit tied to emissions factors of transportation fuel. In other words, it is not a flat payment. The credit depends on the carbon intensity of the fuel and on how the rule measures the full lifecycle footprint.

That is why Clean Energy's dairy-RNG positioning matters. The company says RNG produced from dairy manure achieves a negative carbon-intensity rating. If final guidance keeps a workable pathway for lower- or negative-emission fuels, the credit value per gallon could remain meaningful. If the rule makes attribution more difficult or narrows how lifecycle emissions are calculated, the upside becomes harder to model.

So the up-to-$5M potential 45Z upside is best treated as sentiment leverage, not a guaranteed earnings add-on. A favorable read-through would matter because it would make the credit stream easier for investors to underwrite, not just because of the dollar amount involved. For context, Gevo said it unlocked significant carbon business revenue expected to begin in the third quarter and raised its own full-year non-GAAP adjusted EBITDA outlook to more than $60 million. That does not prove 45Z upside for Clean Energy, but it does show other renewable-fuel companies are already treating carbon-related revenue as a real operating factor.
