Q1 2026 Gross Profit of $9.2 Million Increased $11.0 Million

Q1 2026 Net Income of $4.0 Million, or $0.05 per Share, Improved $16.0 Million

Q1 2026 Adjusted EBITDA of $4.7 Million Improved $9.1 Million Compared to Q1 2025

PEKIN, Ill., May 06, 2026 (GLOBE NEWSWIRE) -- Alto Ingredients, Inc. (NASDAQ:ALTO), a producer and distributor of renewable fuels, essential ingredients and specialty alcohols, reported its financial results for the quarter ended March 31, 2026.

"In a seasonally weak period for Alto and the industry, we delivered profitability on an adjusted EBITDA and net income basis through the contributions of strong export sales, higher crush margins and incremental earnings from Section 45Z tax credits. Even without the contribution of the tax credits we were profitable," said President and Chief Executive Officer Bryon McGregor. "Our strategic realignment, combined with our efforts to improve our operational model and the stability of our business have enhanced our earnings power."

Added Mr. McGregor, "Looking ahead, our priorities are straightforward: improve utilization and reliability; execute our 2026 optimization and capital projects on time and on budget; and leverage the flexibility we have with multiple revenue streams to respond to market shifts and perform profitably through commodity cycles. In addition, we are focused on expanding the value we capture from 45Z tax credits and on optimally monetizing the value of our biogenic CO₂ production across our facilities to lower our carbon footprint. Through our focus on these priorities, we remain committed to enhancing the value of our assets."

Financial Results for the Three Months Ended March 31, 2026 Compared to 2025

Net sales were $224.7 million, compared to $226.5 million.
Cost of goods sold was $215.5 million, compared to $228.3 million.
Gross profit was $9.2 million, compared to a gross loss of $1.8 million. Gross profit was positively impacted by an $8.1 million net unrealized gain on derivatives.
Selling, general and administrative expenses were $6.7 million, compared to $7.2 million.
Interest expense was $2.2 million, compared to $2.7 million.
Net income attributable to common stockholders was $4.0 million, or $0.05 per diluted share, compared to a net loss of $12.0 million, or $0.16 per share.
Adjusted EBITDA was $4.7 million, compared to negative $4.4 million, an increase of $9.1 million.

Cash and cash equivalents at March 31, 2026 were $20.3 million, compared to $23.4 million at December 31, 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 (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.
