Financial Highlights

Reported for the three months ending December 31, 2014:

Reported for the year ending December 31, 2014:

Neil Koehler, the Company’s president and CEO, stated: “Our record financial and operating results in 2014 are a culmination of numerous efficiency and debt reduction initiatives we implemented over the past several years combined with strong market fundamentals. With our solid balance sheet and cash flow, we are both reinvesting in our production assets and pursuing a merger with Aventine that will redefine Pacific Ethanol’s competitive position in the ethanol industry, making us the fifth largest ethanol producer and marketer in the country. In 2015, we are focused on driving sustained profitable growth through successfully closing the Aventine merger, integrating our combined companies, further improving plant efficiencies, diversifying feedstock, introducing new revenue streams and pursuing advanced biofuels production.”

Financial Results for the Three Months Ended December 31, 2014

Net sales were $256.2 million for the fourth quarter of 2014, compared to $215.3 million for the fourth quarter of 2013. The increase in net sales was attributable to an increase in total gallons sold, slightly offset by a reduction in the Company’s average sales price per gallon.

Gross profit was $18.4 million for the fourth quarter of 2014, compared to $21.6 million for the fourth quarter of 2013. The decline in gross profit was due to particularly strong production margins in the fourth quarter of 2013.

Selling, general and administrative (“SG&A”) expenses were $4.7 million for the fourth quarter of 2014, compared to $4.4 million for the fourth quarter of 2013. The increase in SG&A expenses reflect an increase in professional fees related to the pending Aventine merger of approximately $1.0 million, partially offset by a reduction in year-end compensation expense of approximately $0.8 million.

Operating income for the fourth quarter of 2014 was $13.6 million, compared to $17.2 million for the same period in 2013.

Fair value adjustments resulted in income of $2.2 million for the fourth quarter of 2014, compared to an expense of $2.5 million for the same period in 2013.

Interest expense, net was $1.1 million for the fourth quarter of 2014, compared to $3.7 million for the fourth quarter of 2013. This reduction is due to the Company’s significantly reduced debt balances in 2014.

Provision for income taxes was $1.5 million for the fourth quarter of 2014. In the fourth quarter, the Company finalized its estimate of net operating losses available to be utilized in 2014, which resulted in a reduced provision for income taxes for the quarter.

Income available to common stockholders for the fourth quarter of 2014 was $12.2 million, or $0.50 per diluted share, compared to $8.3 million, or $0.54 per diluted share, for the fourth quarter of 2013.

Adjusted Net Earnings, which excludes fair value adjustments and warrant inducements and extinguishments of debt, was $10.0 million, or $0.41 per diluted share for the fourth quarter of 2014, compared to Adjusted Net Earnings of $12.0 million, or $0.79 per diluted share for the same period in 2013.

Adjusted EBITDA was $16.3 million for the fourth quarter of 2014, compared to Adjusted EBITDA of $18.3 million for the fourth quarter of 2013.

Financial Results for the Year Ended December 31, 2014

Net sales were a record $1.1 billion for 2014, compared to $908.4 million for 2013.

Gross profit was a record $108.5 million for 2014, compared to $32.9 million for 2013.

Operating income for 2014 was a record $91.4 million, compared to $18.9 million for 2013.

Net income available to common stockholders for 2014 was $20.0 million, or $0.88 per diluted share, compared to a loss of $2.0 million, or $0.17 per diluted share, for 2013.

Adjusted Net Earnings for 2014 was $59.9 million, or $2.64 per diluted share, compared to Adjusted Net Earnings of $2.0 million, or $0.16 per diluted share, for 2013.

Adjusted EBITDA for 2014 was a record $95.0 million, compared to Adjusted EBITDA of $28.6 million for 2013.

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 Net Earnings as unaudited earnings before fair value adjustments and warrant inducements and gain (loss) on extinguishments of debt. The company defines Adjusted EBITDA as unaudited net income (loss) attributed to Pacific Ethanol before interest, provision for income taxes, depreciation and amortization, fair value adjustments and warrant inducements and noncash gain (loss) on extinguishments of debt. Tables are provided at the end of this release that provide a reconciliation of Adjusted Net Earnings and Adjusted EBITDA to their most directly comparable GAAP measures. Management provides these non-GAAP measures 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 Net Earnings and Adjusted EBITDA are not measures of financial performance under GAAP, and should not be considered alternatives 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 Net Earnings and Adjusted EBITDA have limitations as analytical tools and you should not consider these measures in isolation or as a substitute for analysis of the company’s results as reported under GAAP.
