Aemetis Reports First Quarter 2023 Financial Results

CUPERTINO, Calif. – May 4, 2023 - Aemetis, Inc. (NASDAQ: AMTX), a renewable natural gas and renewable fuels company focused on negative carbon intensity products, today announced its financial results for the three months ended March 31, 2023.

“Revenues for the first quarter of 2023 reflect our decision in late 2022 to idle the Keyes plant due to a 500% increase in energy cost brought about by insufficient natural gas storage in the Western United States, California in particular, and the resulting price spike that made continuing operations uneconomic. From December through mid-March, exorbitant pricing for natural gas would have resulted in a $12 million loss for the ethanol business, so management made the difficult but necessary decision to temporarily idle production and focus the plant staff on implementing a significant maintenance turnaround and mechanical reconfiguration related to the company’s energy efficiency projects,” said Todd Waltz, Chief Financial Officer of Aemetis.  “Investments in capital projects related to the reduction of the carbon intensity of Aemetis ethanol were $7.6 million for the first quarter of 2023 as our engineering and construction teams moved forward with the initiatives outlined in our Five-Year Plan,” added Waltz.

“We are pleased with the milestones accomplished during the first quarter of 2023 regarding our energy efficiency projects as well as bringing the six dairy digesters, a 40 mile biogas pipeline and RNG facility with utility interconnect into service in late January. Due to high natural gas prices in California during the first quarter, we took the opportunity to complete significant maintenance and upgrades to the Keys ethanol plant,” said Eric McAfee, Chairman and CEO of Aemetis.  “With natural gas now at a reasonable pricing range and the maintenance turn-around complete, we expect to restart the plant during the second quarter of 2023.”

The energy efficiency and Renewable Natural Gas milestones reflect our execution of the projects under our Five-Year Plan that produce negative carbon intensity products to rapidly grow value for Aemetis shareholders. We invite investors to review the Aemetis Corporate Presentation on the Aemetis home page prior to the earnings call.

Today, Aemetis will host an earnings review call at 11:00 a.m. Pacific time (PT).

Financial Results for the Three Months Ended March 31, 2023

Revenues during the first quarter of 2023 decreased to $2.2 million compared to $52.0 million for the first quarter of 2022. Our North America division entered an extended maintenance cycle during the last two weeks of December 2022 which extended through the end of the first quarter, allowing for acceleration of several important ethanol plant energy efficiency upgrades. Working on plant maintenance and upgrades during Q1 enabled the plant to avoid the high natural gas prices in Northern California during the first quarter driven by cold weather. The Dairy Natural Gas segment produced 21,300 MMBtu from 6 dairy digesters and the RNG was placed in underground storage to preserve the carbon credits. India Biodiesel recognized $1.5 million of revenue from private customers.

Gross loss for the first quarter of 2023 was $1.3 million, compared to a $3.1 million loss during the first quarter of 2022.

Selling, general and administrative expenses increased to $10.8 million during the first quarter of 2023 from $7.3 million during the same period in 2022, driven primarily by $2.7 million of fixed costs of goods sold charged to selling, general and administrative during the idle time.

Operating loss was $12.1 million for the first quarter of 2023, compared to operating loss of $10.4 million for the same period in 2022.

Interest expense, excluding accretion of Series A preferred units in the Aemetis Biogas LLC subsidiary, increased to $9.0 million during the first quarter of 2023 compared to $6.3 million during the first quarter of 2022. Additionally, our Aemetis Biogas initiative recognized $5.6 million of accretion of preference payments during the first quarter of 2023 compared to $1.6 million during the first quarter of 2022.

Net loss was $26.4 million for the first quarter of 2023, compared to net loss of $18.3 million for the first quarter of 2022.

Cash at the end of the first quarter of 2023 was $4.1 million compared to $4.3 million at the close of the fourth quarter of 2022. Investments in capital projects related to the reduction of the carbon intensity of Aemetis ethanol were $7.6 million for the first quarter of 2023.

NON-GAAP FINANCIAL INFORMATION

We have provided non-GAAP measures as a supplement to financial results based on GAAP. A reconciliation of the non-GAAP measures to the most directly comparable GAAP measures is included in the accompanying supplemental data. Adjusted EBITDA is defined as net income/(loss) plus (to the extent deducted in calculating such net income) interest expense, income tax expense, intangible and other amortization expense, accretion expense, depreciation expense, and share-based compensation expense.

Adjusted EBITDA is not calculated in accordance with GAAP and should not be considered as an alternative to net income/(loss), operating income or any other performance measures derived in accordance with GAAP or to cash flows from operating, investing or financing activities as an indicator of cash flows or as a measure of liquidity. Adjusted EBITDA is presented solely as a supplemental disclosure because management believes that it is a useful performance measure that is widely used within the industry in which we operate. In addition, management uses Adjusted EBITDA for reviewing financial results and for budgeting and planning purposes. EBITDA measures are not calculated in the same manner by all companies and, accordingly, may not be an appropriate measure for comparison.
