Rhea-AI Filing Summary

Aemetis, Inc. reported that its subsidiary Aemetis Biogas LLC entered into an Eleventh Waiver and Amendment to its Series A Preferred Unit Purchase Agreement with Protair-X Technologies Inc. and Third Eye Capital Corporation. The amendment extends the deadline to redeem all outstanding Series A Preferred Units from December 31, 2025 to April 30, 2026 and sets the aggregate redemption price at $114.7 million, which reflects prior payments and a $2 million fee for this amendment.

Insights

Corporate finance and credit analyst

Aemetis delays a major preferred redemption and outlines costly fallback debt terms.

The amendment pushes Aemetis Biogas LLC’s obligation to redeem all Series A Preferred Units to April 30, 2026 and fixes the aggregate redemption price at $114.7 million, including a $2 million fee tied to this amendment. This highlights a sizable financing commitment at the subsidiary level.

If Aemetis Biogas LLC does not redeem by the new date, it would instead enter a credit agreement effective May 1, 2026, maturing May 1, 2027. That facility would accrue interest at the greater of 16.0% or the prime rate plus 10.0%, indicating a high-cost borrowing structure.

The contemplated credit agreement would be guaranteed by Aemetis, Inc. and several subsidiaries and secured by their assets. This structure concentrates repayment and collateral obligations at the broader group level. Future disclosures may clarify whether the preferred units are redeemed by the deadline or the credit agreement becomes effective.

The PUPA Eleventh Amendment further provides that if ABGL does not redeem the Preferred Units by the Redemption Date, ABGL will enter into a credit agreement with Protair-X and Third Eye Capital Corporation, in substantially the form attached to the PUPA Eleventh Amendment (the "Credit Agreement"), which entry would satisfy ABGL's redemption obligation. Once the Credit Agreement is entered, its key terms would include: (i) an effective date of May 1, 2026, (ii) a maturity date of May 1, 2027, (iii) accruing interest at a rate equal to the greater of 16.0% and the prime rate plus 10.0%, (iv) a requirement for Aemetis, Inc. and several of its subsidiaries (the "Guarantors") to guarantee ABGL's obligations, and (v) a grant of a security interest in the assets of ABGL and the Guarantors.
