Xethanol Corporation (AMEX: XNL - News), a renewable energy company, today reported financial results for the first quarter ended March 31, 2008.

For the three months ended March 31, 2008, the company reported a net loss of $2.0 million, or ($0.07) per share, as compared to a $5.5 million net loss, or ($0.19) per share, for the same period of the prior year. The reduction in the net loss was primarily related to significantly lower general and administrative costs and equity compensation expenses compared to the same period in the prior year, as well as a gain from the sale of a portion of the company’s investment in New Generation Biofuels Holdings, Inc. (formerly named H2Diesel Holdings, Inc.).

David Ames, President and CEO of Xethanol, commented, “We continue to make progress in improving our operating results, particularly by reducing our cost structure to fit the current size of the business and market conditions. We are also evaluating potential merger partners, investments, new business product lines, and acquisitions.”

Review of the Quarter

The company reported net sales of $3.0 million in first quarter 2008, which was a 24.3% increase over the same period in the prior year. Cost of goods sold was $3.6 million for the year compared to $2.9 million in the prior year. The increase was attributable to an increase in gallons of ethanol sold at the company’s Blairstown, Iowa ethanol plant as well as higher costs for corn and fuel for the plant compared to the same period in the prior year.

The company had an operating loss for quarter. Because of the continued high prices for corn and gas, on May 1, 2008 the company temporarily ceased production of ethanol at its Blairstown plant to reduce its operating losses. Management is monitoring the situation closely and evaluating strategies for the plant.

General and administrative (G&A) costs were $1.7 million in first quarter 2008 compared to $2.7 million for the comparable period in the prior year. The reduction in G&A was primarily due to a decrease in legal and accounting fees as well as lower costs associated with the termination of the CoastalXethanol operations and other cost savings measures implemented by management.

During first quarter 2008, the company reported:

1. Lower equity compensation expense of $137,000 as compared to $1.6 million in the same period of the prior year

2. A $757,000 gain on the sale of a portion of the company’s shares of the common stock of New Generation Biofuels Holdings;

3. A $346,000 reduction in the net loss in equity of New Generation Biofuels Holdings.

The company had cash, cash equivalents and marketable securities of $10.1 million at March 31, 2008 and $9.5 million as of May 7, 2008.

Attached are the unaudited consolidated statement of operations for the three months ended March 31, 2008 and 2007 and unaudited consolidated balance sheets at March 31, 2008 and December 31, 2007.
