Alto Ingredients Reports Third Quarter 2021 Results

Sacramento, CA, November 9, 2021 – Alto Ingredients, Inc. (NASDAQ: ALTO), a leading producer of specialty alcohols and essential ingredients, reported its financial results for the third quarter ended September 30, 2021.

“In the third quarter we made significant progress in advancing our strategic initiatives, expanding our essential ingredients business and improving our infrastructure,” said Mike Kandris, CEO of Alto Ingredients. “We launched an enhanced protein project through the installation of Harvesting Technology’s patented CoPromax™ system at our Magic Valley, Idaho facility. At our Pekin campus, we made significant progress on a number of initiatives. We completed our yeast expansion project and will have our upgraded feed dryers operational by year end. We also finished expanding the capacity of our corn oil production and significantly improved the efficiency and reliability of our Pekin wet mill to further support customer demand long term. We are also working on extending the certifications we obtained at the end of 2020 from our ICP distillery to our Pekin wet mill. We expect to complete this effort by the end of this year and by doing so, provide unique redundancy across the entire Pekin campus and further surety of quality supply to our customers.

“Subsequent to quarter end, on November 8th we announced the sale of our Stockton, California fuel-grade ethanol facility, completing the realignment of our fuel-grade ethanol operations we began 21 months ago. The proceeds from these asset sales were integral to our strategy and contributed to the retirement of approximately $150 million dollars in term debt over this same period – thus achieving our stated goal to prepay this expensive and restrictive term debt by year end 2021.

“We have completed or are on track to complete this year a number of projects that will increase our annual EBITDA by $18.5 million starting in 2022. Long-term, we will continue to build on our specialty alcohols and essential ingredients business, focusing our resources on driving profitable growth and progressing our strategic initiatives.”

“Net sales were $306 million, up approximately $100 million from the prior year’s quarter due to an increase in both gallons produced and the average price per gallon sold,” stated Bryon McGregor, CFO of Alto Ingredients. “Last year’s specialty alcohol sales uniquely benefited from a spike in sanitizer and disinfectant demand from COVID-19. When examining costs and bottom line comparatively, the planned outage of our wet mill, as expected, materially impacted our total revenues and cost of goods sold, driving the gross loss in this year’s quarter compared to last year’s gross profit.

“Going forward, while we anticipate continued volatility in sanitizer and disinfectant demand over foreseeable future, we expect a more stable, new demand-supply equilibrium will ultimately be achieved as COVID-19 impacts dissipate. We also expect an increase in fixed-price contracted specialty alcohol sales and growing specially alcohol exports. Our upgraded wet mill facility with significantly improved efficiency and reliability will enable us to further support customer demand long term.”

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 net income (loss) attributed to Alto Ingredients, Inc. before interest expense, interest income, provision (benefit) for income taxes, asset impairments, loss on extinguishment of debt, purchase accounting adjustments, fair value adjustments, 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) attributed to Alto Ingredients, Inc. 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) attributed to Alto Ingredients, Inc. 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.
