Exhibit 99.1

Alto Ingredients, Inc. Reports Fourth Quarter and Year-end 2024 Results

- Implemented Cost Savings Expected to Yield Approximately $8 Million Annually -
- Integrated Accretive Acquisition of a Beverage-grade Liquid CO2 Processor -

- Considering Asset Sales, a Merger or Other Strategic Transactions - 

Pekin, IL, March 5, 2025 – Alto Ingredients, Inc. (NASDAQ: ALTO), a leading producer and distributor of specialty alcohols, renewable fuels and essential ingredients, reported its financial results for the quarter and year ended December 31, 2024.

Bryon McGregor, President and Chief Executive Officer of Alto Ingredients said, “During the fourth quarter of 2024 and the first quarter of 2025, we implemented cost saving initiatives, including cold idling our Magic Valley plant and lowering total company headcount by 16%. We expect these staffing reductions to save approximately $8 million annually beginning in the second quarter of 2025. While ensuring high customer service, we rightsized the company to our smaller organizational footprint to position for long-term sustainable growth.

“On January 1st, we acquired a beverage-grade liquid carbon dioxide processor adjacent to our Columbia site. Bolstering economics and increasing asset valuation, this immediately accretive transaction has a compelling payback of less than two years as well as opportunities for cost synergies and expanded production. At our Pekin Campus, we continue to diligently pursue opportunities to optimize carbon, which has been historically underutilized and undervalued. Lastly, with the assistance of our financial and legal advisors, we are considering a broad range of options, including asset sales, a merger or other strategic transactions to better align the long-term value potential of the company.”

Chief Financial Officer Rob Olander added, “Our restructuring has improved Alto’s financial position going forward. In doing so, during the fourth quarter of 2024, we recognized over $30 million in asset impairments and prior acquisition-related expenses, which reset our base. Combining our reduced expense run rate with our improved performance at the Pekin wet mill, our synergistic acquisition of premium liquid CO2 processing and our entry into the European market, we are optimistic about 2025.”

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, unrealized derivative gains and 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.
