Aemetis, Inc. Enters High-Growth Phase with Dairy RNG Platform Expansion

Aemetis, Inc. (Nasdaq: AMTX) has demonstrated robust growth in its Dairy Renewable Natural Gas (RNG) platform, as highlighted in the recent coverage update by Stonegate Capital Partners. The company's second quarter of 2025 results underscore a pivotal shift towards high-growth, fueled by regulatory approvals, capacity expansion, and favorable policy developments. With eleven digesters producing 106,400 MMBtu of RNG, generating $3.1 million in revenue, Aemetis is on a clear path to scaling its operations.

The California Air Resources Board (CARB) has approved seven new Low Carbon Fuel Standard (LCFS) pathways for Aemetis, with a blended Carbon Intensity (CI) score of -384, significantly enhancing the value of LCFS credits by approximately 120%. This development, alongside the expectation of four additional pathway approvals under CARB’s expedited Tier 1 process, positions Aemetis to capitalize on the growing demand for low-carbon fuels. The company anticipates its RNG capacity to reach 550,000 MMBtus by the end of 2025 and 1.0 million MMBtus by 2026, marking a substantial increase in production capabilities.

Monetization opportunities for Aemetis have expanded, encompassing the sale of RNG molecules, D3 RIN credits, LCFS production tax credits, and section 45Z production tax credits. To date, Aemetis has sold $83 million in Section 48 investment tax credits, generating around $70 million in cash. The company expects the monetization of 45Z credits to become a recurring revenue stream starting in the third quarter of 2025.

Further bolstering its growth trajectory, Aemetis has secured agreements to build hydrogen sulfide (H₂S) removal and compression units for 15 digesters, supporting the scale-up towards its 1.0 million MMBtu/year RNG platform by 2026. Additionally, the company has secured 20-year term USDA-guaranteed financing to fund its expansion efforts.

In its California Ethanol segment, Aemetis is making progress on a $30 million mechanical vapor recompression (MVR) system, expected to reduce natural gas use by 80% and add $32 million in annual cash flow from 2026 onwards. This initiative is set to enhance the efficiency of the Keyes Plant, eliminating margin-related shutdowns experienced in the second quarter of 2025. Ethanol margins have also improved, thanks to the EPA's summer E15 approval in 49 states, lower corn prices, and advancing legislation for year-round E15 in California.

The India Biodiesel segment resumed deliveries in April, contributing $11.9 million in revenue, with the India subsidiary on track for an early 2026 IPO. Aemetis is also exploring entry into ethanol production in India, supported by favorable government pricing policies.

For the second quarter of 2025, Aemetis reported revenue of $52.2 million, up $9.3 million from the first quarter but down from $66.6 million in the same period last year, primarily due to lower year-over-year biodiesel volumes. However, the operating loss improved to $10.7 million from $13.6 million year-over-year, with selling, general, and administrative expenses (SG&A) down $4.5 million sequentially. The net loss narrowed to $23.4 million from $29.2 million, with cash standing at $1.6 million at quarter-end after $3.6 million in CI-reduction and RNG investments.

Aemetis is well-positioned to benefit from four major U.S. policy tailwinds accelerating demand for low-carbon fuels, including CARB’s 20-year LCFS framework, Section 45Z Production Tax Credits, nationwide E15 expansion, and strong low-carbon fuel mandates and incentives. These developments, coupled with a favorable regulatory environment, are expected to facilitate Aemetis’ refinancing initiative, potentially reducing interest expenses significantly.

Stonegate Capital Partners' valuation model for Aemetis, based on a Discounted Cash Flow analysis, suggests a valuation range of $8.30 to $18.77, with a midpoint of $12.39, reflecting the company's growth potential and strategic positioning in the renewable energy sector.
