Aemetis Signs Agreement with NPL Construction Co. for $30 Million Mechanical Vapor Recompression System at Keyes Ethanol Plant

Aemetis, Inc. (NASDAQ: AMTX) a renewable natural gas and renewable fuels company focused on low and negative carbon intensity products, today announced that its Keyes plant subsidiary has signed an engineering, procurement, and construction (EPC) contract with NPL Construction Co., a subsidiary of Centuri Holdings, Inc. (NYSE: CTRI) a $2.6 billion revenue infrastructure services contractor, to install a Mechanical Vapor Recompression (MVR) system at the company's 65 million gallon per year ethanol production facility in Keyes, California, with an estimated total project cost of $30 million.

The project has received approximately $19.7 million in tax credits and grants from the Internal Revenue Service (upon recommendation by the U.S. Department of Energy), California Energy Commission, and Pacific Gas & Electric. The MVR project is scheduled to complete construction in Q2 2026.

Once operational, the MVR system is projected to reduce natural gas usage at the Keyes plant by approximately 80%, generating an estimated $32 million of incremental annual cash flow from energy savings, increasing LCFS credits from a double-digit reduction in the carbon intensity of ethanol produced, and increasing transferrable Section 45Z production tax credits.

"NPL's construction of the MVR project is designed to deliver a high-return, high-impact upgrade to our California ethanol facility with minimal equity dilution," said Eric McAfee, Chairman and CEO of Aemetis. "The MVR system is expected to materially improve operating margins, strengthen cash flow, and advance our commitment to reducing emissions from the renewable fuel we produce."

"We are pleased to expand our partnership with Aemetis in pursuit of a shared public-private commitment to advancing California's clean energy goals through the production of renewable fuels," said Centuri US Gas President Dylan Hradek.  "We have the people and capabilities to provide the energy infrastructure solutions required to build a more sustainable future and look forward to our role in this project."

The MVR project builds on the company's multi-year strategy to expand Dairy Renewable Natural Gas production, with 18 dairies operating or under construction and the recent approval of seven CARB LCFS pathways. The MVR system strengthens California Ethanol operations through energy efficiency and margin expansion while capturing value from powerful regulatory tailwinds including rising LCFS credit prices, Section 45Z production tax credit monetization, and expected E15 (15% ethanol blend) adoption in California.
