Brookings, S.D., March 11, 2008 – VeraSun Energy Corporation (NYSE: VSE), a leading producer of ethanol, today announced its financial results for the three months and year ended December 31, 2007.

“We are pleased to announce a solid quarter and year. Fiscal year 2007 included significant milestones for the Company as we recorded more than $848 million of revenues in our fifth year of operations. We significantly increased our production capacity while improving operating efficiencies,” said Don Endres, CEO and Chairman of VeraSun. “Our operating performance and safety record have been exceptional. In the fourth quarter, we produced 142.1 million gallons and sold 134.4 million gallons of ethanol – our highest level of output to date with an average production rate of over 105% of nameplate capacity for the year,” said Endres. “During 2007, we positioned the company to be one of the largest and low cost producers in 2007 and we remain confident that a strong foundation has been laid for our continued leadership in the biofuels industry.”

Fourth Quarter 2007 Financial Highlights

Total revenues, which includes revenue from the sale of ethanol, distillers grains and VE85™, increased by $165.9 million, or 113%, to $312.4 million for the three months ended December 31, 2007 from $146.5 million for the three months ended December 31, 2006. The increase in total revenues was primarily the result of a 131% increase in ethanol volume sold, partially offset by a decrease in average ethanol prices of $0.30 per gallon, or 14%, compared to the three months ended December 31, 2006. Ethanol production increased by 82.5 million gallons, or 138%, as a result of the added capacity from bringing the Charles City, Iowa, facility on-line in April, the Linden, Indiana facility on-line in August and the Albion, Nebraska facility on-line in October.

Net sales from ethanol increased $125.6 million, or 99%, to $251.5 million for the three months ended December 31, 2007 from $125.9 million for the three months ended December 31, 2006. The impact of increased volume, primarily from the additional Charles City and Linden capacity, was $165.4 million, partially offset by a $39.8 million reduction due to lower prices. The average price of ethanol sold was $1.87 per gallon for the three months ended December 31, 2007 compared to $2.17 per gallon for the three months ended December 31, 2006.

Net sales from co-products increased $36.5 million, or 202%, to $54.6 million for the three months ended December 31, 2007 from $18.1 million for the three months ended December 31, 2006. The impact of increased volume from the additional Charles City, Linden, and Albion capacity was $26.4 million and the impact of higher prices was $10.1 million.

Net sales of VE85^TM, our branded E85 product, increased $3.0 million, or 166%, to $4.8 million for the three months ended December 31, 2007 from $1.8 million for the three months ended December 31, 2006, primarily due to a 17% increase in the number of retail outlets selling our product.

Gross profit decreased $10.0 million to $30.8 million for the three months ended December 31, 2007 from $40.8 million for the three months ended December 31, 2006. The decrease in gross profit was primarily due to higher corn costs and lower ethanol prices, partially offset by an increase in ethanol volume produced in the 2007 period compared to the 2006 period.

Fiscal Year 2007 Financial Highlights:

Revenues grew to $848.3 million for the year, an increase of $290.5 million, or 52% from 2006. This growth was driven by an increase in ethanol volume sold of 128.6 million gallons.

Net income for the year was $26.6 million. Diluted EPS was $0.31 for 2007. EBITDA was $90.4 million. In 2006, net income for the year was $75.7 million, diluted EPS was $1.03 and EBITDA was $177.6 million.

Operational Highlights:

During 2007, the Company experienced growth in production volume primarily due to its Charles City, Iowa facility successful start-up in April, the start-up of its Linden, Indiana facility in August and the start-up of Albion, Nebraska in October. Total ethanol sales increased to 134.4 million gallons during the fourth quarter of 2007, a 131% increase in sales from the fourth quarter of 2006.

The Company began construction on its facilities in Welcome, Minnesota, and Hartley, Iowa and expects to begin start-up operations at both plants by the end of the second quarter of 2008. The Company expects to start-up the Bloomingburg, Ohio plant by the end of the first quarter of 2008.
