PEKIN, Ill., March 04, 2026 (GLOBE NEWSWIRE) -- 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, 2025.

President and Chief Executive Officer Bryon McGregor commented, "The fourth quarter capped a year of strong execution and marked a pivotal milestone in our strategic realignment. Over the course of 2025, we completed the heavy lifting of addressing losses at underperforming assets, removing structural costs and repositioning our portfolio toward higher-value and more consistent revenue streams, and we are moving forward with plans to improve our return on assets.

"For the fourth quarter, gross profit reached $15.2 million, an increase of $16.6 million; net income was $21.5 million, improving $63.5 million; and Adjusted EBITDA was $27.9 million, increasing $35.6 million, compared to the prior-year period. Higher crush margins, generating qualified 45Z credits and strong renewable fuel export sales were major contributors to improved performance for the quarter."

Mr. McGregor continued, "We entered 2026 in a position of greater strength, with a leaner cost structure, an improved ability to navigate market volatility and a clearer strategy to drive higher-margin diversification and enhance asset values. During the year, we intend to stay focused on driving profitability and executing on opportunities to grow earnings, including enhancing and expanding our production capabilities, increasing renewable fuel exports, leveraging the demand for liquid CO2, and monetizing additional 45Z tax credits. As in 2025, we will maintain strong cost discipline and prioritize the highest ROI projects. I am proud of the progress our team has made and excited about the path forward."

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 (benefit) for income taxes, asset impairments, unrealized derivative gains and losses, acquisition-related expense, excess insurance proceeds 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.
