Advanced BioEnergy to Sell Nebraska Ethanol Plant – South Dakota Operations to Continue

MPLS, Minn. – Advanced BioEnergy, LLC announced earlier this week its plans to sell its Fairmont, Neb., ethanol plant to Wichita-based Flint Hills Resources. The transaction is expected to close later this year, subject to regulatory approval; details of the transaction can be found in the company’s recent 8K filed with the Securities and Exchange Commission.

The Fairmont ethanol plant began production in October 2007. It has an annual capacity of over 115 million gallons, produces more than 320,000 tons of dried distillers grains each year and over 18 million pounds of non-food grade corn oil. The plant employs approximately 50 people.

The company believes the transaction will be beneficial to all parties including its more than 1,200 unit holders. Concurrently with closing, Advanced BioEnergy will settle the remainder of the debt held at ABE Fairmont, LLC. The company will continue to operate its plants located in Aberdeen and Huron, South Dakota. The total production capacity of the South Dakota operations is approximately 85 million gallons per year.

“The transaction with Flint Hills Resources represents a milestone for our company and demonstrates our continued dedication to creating value for our unit holders even in the most challenging environments,” said Scott Brittenham, Chairman of the Board of Advanced BioEnergy. “We will continue to work toward increasing value for our unit holders through improving operational efficiencies and product innovation at our South Dakota plants.”

The company has focused its efforts in South Dakota on yield improvement initiatives over the past year in addition to the deployment of non-food grade corn oil extraction at its Aberdeen, South Dakota plant.

Once the sale of the Fairmont, NE plant is completed later this year, Advanced BioEnergy will continue to evaluate the best course for the remainder of its operations in South Dakota. While immediate plans are to continue operations of its two ethanol plants in Huron and Aberdeen, South Dakota, the company continues to weigh its options in the face of a challenging margin environment for ethanol.
