Exhibit 99.1

Pacific Ethanol Reports Second Quarter 2018 Results

Sacramento, CA, August 8, 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 six months ended June 30, 2018.

Neil Koehler, Pacific Ethanol’s president and CEO, stated: “Even with a challenging first half, we believe market fundamentals remain strong, supporting better production margins in the second half of the year. However, questionable regulatory actions have reduced short-term ethanol demand in both domestic and export markets impacting both Pacific Ethanol and the ethanol industry as a whole. During this period of continued compressed and volatile production margins, our focus remains on initiatives and investments to reduce costs, improve yields, lower carbon scores, and maintain a healthy balance sheet. We are benefiting from increased product diversification that supports stronger margins and lessens our exposure to commodity price fluctuations in the fuel ethanol markets.”

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.
