Key catalyst

Keyes MVR startup and evidence of lower gas intensity • 2026-09-30

Expected move: -4%

Biggest risk

The bear case remains dominant in the near term because the company still faces a going-concern warning, meaningful dependence on lender cooperation, and a hard late-April or May 1 financing/restructuring checkpoint tied to the ABGL preferred-unit obligation [#10-K-2026-03-16]. Even if projects are strategically attractive, equity holders remain exposed to refinancing, dilution, and execution risk before operational wins can matter.

Invalidation

Break below $1 or thesis failure.

What would change my mind?

The constructive case is that Aemetis already has some real operating traction: the RNG segment generated positive EBITDA in 2025, additional digesters are expected to come online in Q2 2026, and the MVR project could improve ethanol margins if it starts up on time and performs as expected [#10-K-2026-03-16]. At a $105.6 million market cap and $2.64 anchor price, the equity still carries meaningful upside optionality if liquidity pressure eases and operating improvements begin showing up in cash flow.

Commentary

Primary-source evidence still supports a cautious monitoring view rather than a clean bullish turn. The positive side of the file is real but mostly operational: the RNG segment generated positive EBITDA in 2025, twelve digesters were operating at year-end, the next set of digesters is expected to begin producing biogas in the second quarter of 2026, and the Keyes MVR project is expected to become operational in 2026 with meaningful fuel-intensity benefits [#10-K-2026-03-16]. The stronger counterweight is financial: Aemetis disclosed substantial doubt about continuing as a going concern over the next twelve months, and the ABGL amendment creates a near-dated redemption or replacement-credit test around April 30 to May 1, 2026 [#10-K-2026-03-16]. The March 16, 2026 8-K announcing the dismissal of RSM and planned engagement of KPMG does not change the core thesis, but it reinforces that investors are still underwriting financing and reporting credibility before they can reward longer-dated operating upside [#8-K-2026-03-16].

Keyes MVR startup and evidence of lower gas intensity
Aemetis says the Mechanical Vapor Recompression system at the Keyes plant is expected to become operational in 2026, with the project intended to cut natural gas consumption materially and improve ethanol economics through lower fuel costs plus better LCFS and Section 45Z capture. The stock likely needs proof of commissioning and realized operating benefit before this becomes a durable rerating driver [#10-K-2026-03-16].

Short-term Catalysts

Next few weeks

Late-April redemption or replacement financing deadline
2026-05-01
The clearest near-term swing factor is whether ABGL redeems its Series A Preferred Units by April 30, 2026 or enters the replacement credit agreement effective May 1, 2026. The 2025 10-K also states there is substantial doubt about Aemetis' ability to continue as a going concern over the next twelve months, so even a temporary extension would mainly reduce immediate liquidity pressure rather than fully clear the balance-sheet overhang [#10-K-2026-03-16].
Prob 55% • Move 22% • Priced-in 75%

Months to a year

RNG digester expansion and tax-credit monetization
2026-12-31
The 10-K says the RNG segment had positive EBITDA in 2025, twelve digesters were operating at year-end, the next set of digesters is expected to begin producing biogas in the second quarter of 2026, and management plans to continue monetizing Section 45Z credits. If Aemetis converts that operating progress into sustained cash generation, it could begin offsetting some of the current distressed-liquidity discount, but financing availability remains the gating factor [#10-K-2026-03-16].

Risks

Failure to redeem or refinance the ABGL preferred obligation by the late-April 2026 deadline could intensify liquidity stress or force unfavorable terms.
Going-concern risk and dependence on lender cooperation remain explicit in the 2025 10-K.
MVR commissioning delays or weaker-than-expected operating benefits would reduce the credibility of the ethanol-margin improvement thesis.
RNG expansion depends on financing availability, successful digester construction, and continued monetization of LCFS and Section 45Z economics.
The March 2026 auditor transition from RSM to KPMG is not thesis-changing by itself, but it keeps reporting execution and control credibility in focus [#8-K-2026-03-16].

Peers

Symbol	Summary
EPSN	Loose same-sector microcap peer from the candidate set. It is more useful as a small-cap energy balance-sheet and valuation reference than as a direct operating analogue for Aemetis' ethanol, RNG, and biodiesel mix.
PROP	Another loose microcap energy comparison with limited product overlap. It helps frame financing sensitivity and risk appetite for subscale energy equities, but it is not a clean read-through for Aemetis' renewable fuels execution.
