  • Aemetis, Inc. announced its ethanol & renewable natural gas (RNG) subsidiaries received funds from selling $18 million in Section 45Z Clean Fuel Production Tax Credits.
  • The sales comprised $6 million from 2025 ethanol production & $12 million from year-to-date 2026 ethanol & RNG production.

  • CEO Eric McAfee noted these are the company's second & third 45Z transactions in six months, citing expectations for future sales driven by planned RNG volume increases & efficiency upgrades at the Keyes plant.
