Green Plains Reports Fourth Quarter and Full-Year 2012 Financial Results

Results for the Fourth Quarter of 2012

Results for the Full Year of 2012

OMAHA, NEB. (GLOBE NEWSWIRE) – February 6, 2013 – Green Plains Renewable Energy, Inc. (NASDAQ: GPRE) announced today its financial results for the fourth quarter and full year ended December 31, 2012. Net income attributable to Green Plains for the full year of 2012 was $11.8 million, or $0.39 per diluted share, compared to net income of $38.4 million, or $1.01 per diluted share, in 2011. Revenues were $3.5 billion for 2012 compared to $3.6 billion in 2011.

For the quarter ended December 31, 2012, net income attributable to Green Plains was $33.0 million, or $0.94 per diluted share, compared to $13.3 million, or $0.36 per diluted share, for the same period in 2011. Revenues were $883.7 million for the fourth quarter of 2012 compared to $922.8 million during the same period in 2011.

“All of our business segments reported positive operating income during both the fourth quarter and the last half of 2012. We believe this demonstrates the effectiveness of our low-cost platform and our ability to manage risk. For the fourth year in a row, our business was profitable and, with the sale of the 12 grain elevators, we continue to focus on creating value for our shareholders,” stated Todd Becker, President and Chief Executive Officer. “We ended 2012 with $280 million in cash and the lowest ethanol plant debt in our history. This positions us for the future to take advantage of growth and diversification opportunities and to continue to withstand the cyclicality of our business.”

“The forward curve for ethanol margins has not given our team a reason to execute significant amounts of forward hedges. Recently, nearby margins have recovered somewhat but remain below historical levels. With that said, our growth in non-ethanol operating income over the last two years will continue to cushion the effect of a compressed margin structure,” said Becker. “We expect to generate over $60 million of non-ethanol operating income this year, even considering the recent sale of certain agribusiness assets.”

In December 2012, Green Plains completed the previously-announced sale of 12 grain elevators located in northwestern Iowa and western Tennessee. The sale resulted in an after-tax gain of $26.3 million which is included in fourth quarter 2012 results. Excluding the gain on the sale of agribusiness assets, net income attributable to Green Plains was $6.7 million, or $0.21 per diluted share, for the fourth quarter.

“Over the next two years, we plan to realign our agribusiness investment,” stated Becker. “We plan to add between five and ten million bushels of grain storage capacity per year. These assets will be located around our ethanol plants to take advantage of our current infrastructure and enhance our corn origination and trading capabilities. Redefining our agribusiness strategy in this way should allow us to leverage our seven million ton processing capacity to aggressively compete for first-handle grain margins. This minimal investment per bushel should provide solid long-term returns for our shareholders.”

Full-year 2012 EBITDA, which is defined as earnings before interest, income taxes, noncontrolling interests, depreciation and amortization, was $115.5 million compared to $148.6 million in 2011. Green Plains had $280.1 million in total cash and equivalents and $121.4 million available under committed loan agreements at subsidiaries (subject to satisfaction of specified lending conditions and covenants) at December 31, 2012. For reconciliations of EBITDA to net income attributable to Green Plains, see “EBITDA” below.

Consolidated Financial Results

The following are consolidated statements of operations for Green Plains (in thousands, except per share amounts):

Revenues decreased $39.1 million for the three months ended December 31, 2012 compared to the same period in 2011 primarily due to lower ethanol revenues. The decline in ethanol revenues was due to lower volumes sold and lower average prices. Gross profit decreased $10.1 million for the three months ended December 31, 2012 compared to the same period in 2011 primarily as a result of unfavorable ethanol production margins. Operating income increased by $36.3 million primarily due to a gain on the sale of agribusiness assets offset by lower ethanol production margins. The Company recorded income tax expense of $26.1 million for the three months ended December 31, 2012 compared to $9.5 million for the same period in 2011. The effective tax rate increased for the three months ended December 31, 2012, which impacted the overall effective tax rate for 2012, as a result of adjustments in state tax rates and tax credits primarily resulting from the sale of agribusiness assets.

Weighted average shares outstanding decreased due to share repurchases that were completed in September 2011 and in March 2012. Weighted average shares outstanding for diluted earnings per share purposes for the three and twelve months ended December 31, 2011, and for the three months ended December 31, 2012, reflect additional shares outstanding under the as-if-converted method of accounting for the convertible notes. For the twelve months ended December 31, 2012, the Company’s net income and weighted average number of common shares outstanding are not adjusted since the effect would be antidilutive. The following summarizes the effects of this method on net income attributable to Green Plains and weighted average shares outstanding for the periods indicated (in thousands):

Revenues in the ethanol production segment decreased by $44.2 million for the three months ended December 31, 2012 compared to the same period in 2011. The decrease in revenue was due to lower average prices for ethanol and the decision, in response to unfavorable operating margins, to temporarily reduce ethanol production volumes at certain ethanol plants. The ethanol production segment produced 168.5 million gallons of ethanol, which represents approximately 91 percent of production capacity, during the three months ended December 31, 2012.

Cost of goods sold in the ethanol production segment decreased by $36.8 million for the three months ended December 31, 2012 compared to the same period in 2011. Consumption of corn decreased by 4.6 million bushels and the average cost per bushel increased by 17.7% during the three months ended December 31, 2012 compared to the same period in 2011. Average ethanol yield was 2.82 gallons per bushel for the three months ended December 31, 2012 compared to 2.81 gallons per bushel in the same period in 2011. The slight yield increase was primarily due to process improvements implemented throughout the platform and slowed production rates at certain of our plants. Depreciation and amortization expense for the ethanol production segment was $11.0 and $11.2 million during each of the three month periods ended December 31, 2012 and 2011, respectively. As a result of the factors identified above, gross profit and operating income in the ethanol production segment decreased by $7.4 million and $9.0 million, respectively, for the three months ended December 31, 2012 compared to the same period in 2011.

Corn Oil Production Segment

Revenues in the corn oil production segment decreased by $0.2 million for the three months ended December 31, 2012 compared to the same period in 2011. During the three months ended December 31, 2012, Green Plains sold 36.6 million pounds of corn oil compared to 31.9 million pounds in the same period in 2011. The increase in volume was offset by a 13.5% decrease in average price for the three months ended December 31, 2012 compared to the same period in 2011. Average corn oil yield increased to 0.61 pounds per bushel for the three months ended December 31, 2012 compared to 0.50 pounds per bushel in the same period in 2011 primarily due to process improvements.

Agribusiness Segment

The table below presents key operating data within the agribusiness segment for the periods indicated:

Within the agribusiness segment, revenues decreased by $20.6 million, gross profit decreased by $5.7 million and operating income increased by $43.3 million for the three months ended December 31, 2012 compared to the same period in 2011. The decline in revenues was caused by the disposition of 12 grain elevators in early December 2012, partially offset by increased grain prices as a result of the 2012 drought. The drought also caused an early harvest season which accelerated the timing of gross profit recognition between the third and fourth quarters of 2012. Operating income for the three months ended December 31, 2012 includes a gain on disposal of assets of $47.1 million. Selling, general and administrative expenses for the segment decreased by $2.0 million between the periods due to the sale completed in early December.

Marketing and Distribution Segment

Revenues in the marketing and distribution segment decreased by $42.6 million for the three months ended December 31, 2012 compared to the same period in 2011. The decrease in revenues was primarily due to lower average prices of ethanol and corn oil and lower volumes of ethanol and distillers grains sold. Ethanol revenues decreased by $43.6 million which was partially offset by an increase in distillers grains revenues of $1.2 million. Revenues and gross profit from railcar leasing for the three months ended December 31, 2012 were $5.5 million and $4.3 million, respectively. The Company sold 258.6 million gallons of ethanol within the marketing and distribution segment during the three months ended December 31, 2012 compared to 259.3 million gallons during the same period in 2011. Gross profit and operating income for the marketing and distribution segment increased by $4.8 million and $4.3 million, respectively, for the three months ended December 31, 2012 compared to the same period in 2011 primarily due to profits realized from railcar leasing, which was initiated during 2012.

Non-GAAP Reconciliations

EBITDA

Management uses EBITDA to measure the Company’s financial performance and to internally manage its businesses. Management believes that EBITDA provides useful information to investors as a measure of comparison with peer and other companies. EBITDA should not be considered an alternative to, or more meaningful than, net income or cash flow as determined in accordance with generally accepted accounting principles. EBITDA calculations may vary from company to company. Accordingly, the Company’s computation of EBITDA may not be comparable with a similarly-titled measure of another company. The following sets forth the reconciliation of net income attributable to Green Plains to EBITDA for the periods indicated (in thousands):

Gain on the Sale of Agribusiness Assets

For the quarter ended December 31, 2012, net income attributable to Green Plains was $33.0 million, or $0.94 per diluted share. The sale of 12 grain elevators in December 2012 resulted in an after-tax gain of $26.3 million, or $0.73 per diluted share. Excluding the gain on the sale, net income attributable to Green Plains was $6.7 million, or $0.21 per diluted share for the quarter ended December 31, 2012..
