Aemetis, Inc. reported financial results for the fourth quarter and full year ending December 31, 2025, highlighting substantial growth in its dairy renewable natural gas platform alongside strategic investments in efficiency upgrades. The company's biogas segment achieved a 61% year-over-year increase in dairy RNG production during the fourth quarter, with segment net income reaching $12.2 million for the period. This expansion reflects the growing importance of renewable energy alternatives in reducing carbon emissions while creating economic value.
The financial implications of Aemetis's growth are significant for the renewable energy sector. Full-year 2025 revenues totaled $197.6 million plus production tax credit income of $10.4 million, resulting in total income of $208.0 million. Chief Financial Officer Todd Waltz noted that capital expenditures for carbon intensity reduction and biogas production capacity expansion reached $26 million for 2025. These investments support the company's engineering and construction teams as they advance low carbon initiatives and dairy RNG project buildout. The company's biogas segment increased annual revenues and production tax credits by 53%, demonstrating the financial viability of renewable natural gas production.
Strategic developments across Aemetis's business segments indicate broader industry trends toward sustainable energy solutions. The company's dairy RNG platform reached 12 operating digesters that produced approximately 405,000 MMBtu of renewable natural gas during 2025. Chairman and CEO Eric McAfee emphasized that with RNG production scaling, ethanol plant efficiency improvements underway, and federal clean fuel incentives beginning to be monetized, Aemetis is positioned for meaningful growth in revenue and cash flow through 2026. Policy support from legislation such as the One Big Beautiful Bill and California's approval of year-round E15 in October 2025 creates favorable market conditions for renewable fuels expansion.
The company's ethanol segment represents another area of strategic importance. Aemetis's 65 million gallon per year ethanol plant in Keyes, California generated $158.3 million of revenue and production tax credits during 2025. The company signed an agreement with NPL Construction to complete procurement and installation of a Mechanical Vapor Recompression system at the Keyes plant, which is expected to significantly improve plant economics. When completed, the MVR system is projected to reduce natural gas consumption, lower the carbon intensity of ethanol production, and increase plant cash flow from operations by approximately $32 million per year. This efficiency upgrade demonstrates how technological improvements can enhance both environmental and financial performance in renewable energy operations.
International operations also contribute to Aemetis's renewable energy portfolio. The company's biodiesel production facility in India generated $29.7 million of revenue during 2025, utilizing about 10% of the plant's 80 million gallon per year capacity. India remains a large and growing market for renewable fuels supported by government blending mandates and expanding fuel demand, as well as global geopolitical issues that strongly support biofuels production expansion. The India subsidiary is targeting a public listing in 2026, with a new CFO appointed with IPO experience to facilitate this process.

Regulatory developments further support Aemetis's business model. The California Air Resource Board approved 7 new Low Carbon Fuel Standard pathways for the company's Renewable Natural Gas business, increasing from the negative 150 default value to an average carbon intensity score of negative 380. This regulatory recognition enhances the value of Aemetis's RNG production within California's carbon credit markets. Additionally, the company signed a $27 million agreement with NPL to construct H2S and compression units for 15 new dairy digesters, indicating continued expansion of its biogas infrastructure. These developments illustrate how regulatory frameworks and infrastructure investments intersect to drive growth in renewable energy sectors.
Financial performance metrics reveal both progress and challenges. For the twelve months ended December 31, 2025, revenues and production tax credits were $208.0 million, with biogas reporting $5.3 million and California ethanol reporting $5.1 million from production tax credits that became effective in January 2025. While the company reported a net loss of $77.0 million for the twelve months ending December 31, 2025, this represented improvement from a net loss of $87.5 million during the same period in 2024. Cash at the end of the fourth quarter of 2025 was $4.9 million, compared to $898 thousand at the end of the fourth quarter of 2024, reflecting strengthened liquidity. Investments in low carbon initiatives increased property, plant, and equipment by $26.0 million during the twelve months ending December 31, 2025, demonstrating continued commitment to renewable energy infrastructure.
