CF Industries Files Hart-Scott-Rodino Notification in Connection with Its Proposed Acquisition of Terra Industries

CF Industries Holdings, Inc. (NYSE:CF) today filed notification with the U.S. Department of Justice and the Federal Trade Commission as required under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, relating to its proposed acquisition of Terra Industries Inc. (NYSE: TRA).

"We are committed to a combination of CF Industries and Terra and are confident that the transaction will be approved in all relevant jurisdictions,” said Stephen R. Wilson, chairman, president and chief executive officer of CF Industries. "We continue to believe a combination is in the best interests of both CF Industries and Terra shareholders.”

In addition, CF Industries today posted a report dated September 2, 2008, from the Federal Trade Commission in response to a Congressional inquiry into pricing in the fertilizer industry in North America to www.transactioninfo.com/cfindustries. The report stated, among other findings, that "markets for fertilizer products in different countries are highly integrated, indicating that fertilizer prices are based on world market conditions.” The FTC Staff also "found no indication that changes in concentration in North America had any significant effect on domestic or foreign fertilizer prices.”

On January 15, 2009, CF Industries proposed to acquire all of the outstanding common shares of Terra Industries for 0.4235 shares of CF Industries per common share of Terra Industries. At the time of the announcement, the proposal represented a premium of 34% based on the 30-day volume weighted average prices for the shares of the two companies, and a 29% premium based on the 10-day volume weighted average. Since the announcement, Terra's stock price has increased by over 40%.

Morgan Stanley and Rothschild are acting as financial advisors and Skadden, Arps, Slate, Meagher & Flom LLP is acting as legal counsel to CF Industries.
