Pacific Ethanol Reports Third Quarter 2018 Results

Sacramento, CA, October 31, 2018 – Pacific Ethanol, Inc. (NASDAQ: PEIX), a leading producer and marketer of low-carbon renewable fuels and high-quality alcohol products in the United States, reported its financial results for the three and nine months ended September 30, 2018.

Neil Koehler, Pacific Ethanol’s president and CEO, stated: “We are encouraged by President Trump’s direction to the Environmental Protection Agency to extend E15 availability year-round, nationwide, as this creates a significant growth opportunity for the ethanol industry. The compelling cost, octane and carbon advantages of ethanol provide strong incentives for both increased demand from higher blends and exports. This will tighten existing supply and demand balances and improve production margins. In the current challenging market environment, we are supported by a solid balance sheet and a continued focus on product diversification, cost reductions and carbon advantages.”

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 Pacific Ethanol before interest expense, provision (benefit) for income taxes, asset impairments, 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. 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.
