Exhibit 99.1

Alto Ingredients, Inc. Reports Fourth Quarter and Year-end 2023 Results

- Delivered 2023 Gross Profit of $15.7 Million, Versus Gross Loss of $27.6 Million in 2022 –

- Improved 2023 Net Loss by $13.6 Million and Adjusted EBITDA by $26.5 Million over 2022 –

- Signed Letter of Intent with Vault 44.01 for CO2 Storage -

Pekin, IL, March 11, 2024 – Alto Ingredients, Inc. (NASDAQ: ALTO), a producer and distributor of renewable fuel and essential ingredients and the largest producer of specialty alcohols in the U.S., reported its financial results for the quarter and year ended December 31, 2023. For the fourth quarter of 2023, gross loss improved $18.8 million and Adjusted EBITDA improved $19.0 million over the fourth quarter of 2022. For the full year 2023, gross profit improved $43.2 million and Adjusted EBITDA improved $26.5 million over 2022.

“During 2023, our investments to diversify revenue, improve capacity utilization rates, reduce costs and expand operating margins contributed to our financial improvements and positioned Alto for stronger performance in 2024 and beyond,” said Bryon McGregor, President and CEO of Alto Ingredients. “Currently, the overall outlook for 2024 is favorable, which should lead to crush margin improvements over the next few months and produce positive spreads through most of the year. We are conducting ongoing maintenance across our asset portfolio to increase reliability and production run rates that we expect will position Alto well heading into the more robust summer months.”

Alto is implementing a carbon capture and storage (CCS) program. In a separate release issued today, Alto announced it signed a letter of intent with Vault 44.01 to partner for safe and permanent CO₂ storage deep underground in a secure geologic reservoir located in close proximity to the company’s Pekin campus, thereby substantially reducing CO₂ emissions from the ethanol production process and providing direct value to the surrounding area.

“Additionally, we have prioritized our CCS initiative and are encouraged by recent progress on many aspects, including overall system design, community outreach, financing, EPA application preparation, and vendor negotiations. Further, we are evaluating new options that would enable us to substantially reduce the capital required to pursue CCS, lower our carbon footprint, and reduce our long-term energy costs. Although markets are dynamic, we remain agile and financially prudent and seek to capitalize on the most promising and profitable opportunities. We are enthusiastic about our prospects and confident in our long-term growth strategy,” concluded McGregor.

The company has engaged equipment manufacturers and independent third-party engineers in conjunction with its vendor, Harvesting Technology, to address issues with the Magic Valley facility’s corn oil and high protein system. The team recommended design modifications to achieve the intended production rate, quality, and consistency. To minimize the financial impact of first quarter 2024 negative regional crush margins at the facility and to expedite the installation of additional equipment, the company temporarily hot-idled the plant. The company intends to restart production in the second quarter of 2024, once the upgrades are complete and crush margins have improved.

Unrealized gains and losses on derivatives are commodity price driven, mark-to-market non-cash adjustments of derivative instruments for open positions related to future sales. Reconciliations of prior periods reflecting this change are available on the company’s website.

Use of Non-GAAP Measures

Management believes that certain financial measures not in accordance with generally accepted accounting principles (“GAAP”) are useful measures of operations. The company defines Adjusted EBITDA as unaudited consolidated net income (loss) before interest expense, interest income, provision for income taxes, asset impairments, loss on extinguishment of debt, unrealized derivative gains (losses), acquisition-related expense and depreciation and amortization expense. A table is provided at the end of this release that provides a reconciliation of Adjusted EBITDA to its most directly comparable GAAP measure, net income (loss). Management provides this non-GAAP measure so that investors will have the same financial information that management uses, which may assist investors in properly assessing the company’s performance on a period-over-period basis. Adjusted EBITDA is not a measure of financial performance under GAAP and should not be considered as an alternative to net income (loss) or any other measure of performance under 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 has limitations as an analytical tool, and you should not consider this measure in isolation or as a substitute for analysis of the company’s results as reported under GAAP.
