ITEM 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On April 12, 2010, we made available certain preliminary financial information and operating data underlying our results of operations. Information regarding preliminary financial results for our fiscal quarter ended March 31, 2010 is set forth below:

Recent Developments

Although our financial statements for the quarter ended March 31, 2010 are not yet complete, certain preliminary financial information and operating data underlying our results of operations are available. The following financial information and operating data is not a comprehensive statement of the financial results for Terra Industries Inc. (“Terra”) for the quarter ended March 31, 2010 and has not been reviewed or audited by Terra’s independent registered public accounting firm. The final financial results for the quarter ended March 31, 2010 may vary from our expectations and may be materially different from the preliminary financial information and operating data provided below as the quarterly financial statement close process is not complete and additional developments and adjustments may arise between now and the time the financial results for this period are finalized. Accordingly, you should not place undue reliance on the following financial information and operating data.

Management currently expects Terra’s 2010 first quarter revenues to be approximately $409 million, approximately 3% lower than Terra’s 2009 first quarter revenues of $420 million. This decline is primarily due to lower selling prices for ammonia, UAN and AN. The prior year first quarter selling price benefited from the orders that were previously committed to under higher prices during 2008. The decline in selling prices was partially offset by an increase in UAN and AN sales volume of 34% and 76%, respectively. For the first quarter, natural gas unit costs, net of forward pricing gains and losses, decreased by approximately 27% from $7.37 per MMBtu in 2009 to $5.39 per MMBtu in 2010.

Set forth below is summary operating data for Terra based on management’s current expectations for the quarters ended March 31, 2010 and 2009:
