Deerfield, Illinois — (BusinessWire) — February 17, 2011:  CF Industries Holdings, Inc. (NYSE: CF) today reported fourth quarter 2010 net earnings attributable to common stockholders of $200.3 million, or $2.78 per diluted share, compared to earnings of $51.4 million, or $1.04 per diluted share, in the fourth quarter of 2009.  Fourth quarter pre-tax results included $31.4 million non-cash mark-to-market gains on natural gas derivatives and $15.8 million of business combination costs.  These items increased/(reduced) after-tax earnings per diluted share by $0.27 and $(0.14), respectively.

Net sales were $1.2 billion, up 144 percent from $506.7 million in the 2009 fourth quarter, due to inclusion of Terra net sales of $451.2 million, higher nitrogen volumes, especially for ammonia, and higher product prices.  Year-ago sales and all other 2009 volume and financial data in this release are presented on a pre-acquisition basis, as reported in the prior periods.  Reflecting this basis, total sales volume increased from 2.0 million tons in the 2009 fourth quarter to 3.8 million tons in 2010, largely explained by the inclusion of 1.7 million tons of Terra sales volume.

“In the fourth quarter, we benefited from the increased capability of our expanded platform and a host of favorable external factors,” commented Stephen R. Wilson, chairman and chief executive officer, CF Industries Holdings, Inc.  “Fall application of ammonia and phosphates was particularly strong because of increased expected crop plantings, higher application rates, high crop prices, an early harvest and favorable weather in the U.S. Midwest,” Wilson noted.

Fertilizer prices rose significantly during the quarter due to these domestic demand factors, very strong international markets, low U.S. and world fertilizer inventories and anticipated export restrictions in China.  Increased European demand for nitrates supported North American prices as it reduced availability of urea ammonium nitrate solution (UAN) due to higher ammonium nitrate (AN) production in Europe.

Because of tight supply and attractive prices in North American markets, CF Industries limited phosphate exports and did not export nitrogen products during the fourth quarter of 2010.

Full Year Results

Earnings attributable to common stockholders in 2010 totaled $349.2 million, or $5.34 per diluted share, compared to $365.6 million, or $7.42 per diluted share, in 2009.   CF Industries acquired a controlling stake in Terra Industries on April 5, 2010, and Terra’s results are included in the company’s nitrogen segment results from that date.

Full-year pre-tax results included $288.5 million of business combination costs, a $28.3 million gain on the sale of Terra shares, $9.6 million in non-cash gains from mark-to-market adjustments on natural gas derivatives, and $5.8 million of Peru project development costs.  These items increased/(reduced) after-tax earnings per diluted share by $(3.55), $0.27, $0.09 and $(0.09), respectively.

“We will remember 2010 as the year we made a transformative acquisition and proved our ability to integrate the operations of Terra Industries and CF Industries,” Wilson noted.  “It also was a year of strengthening fundamentals in which our business generated nearly $1.2 billion in cash flow from operations.”

Net sales for 2010 totaled $4.0 billion, up 52 percent from $2.6 billion in 2009.  The increase resulted primarily from the inclusion of Terra net sales of $1.4 billion and higher sales volumes.

For the year, CF Industries invested $258.1 million in capital expenditures.

Nitrogen Fertilizer Segment

CF Industries delivered 3.4 million tons of ammonia, urea, UAN, AN and other nitrogen products during the fourth quarter of 2010.

Ammonia volume of 917,000 tons was sold at an average price of $452 per ton, compared to 305,000 tons at an average price of $308 in the fourth quarter of 2009.  The Midwest ammonia market remained very attractive through the fall due to tight domestic inventories and high demand for wheat pre-plant and for fall application in preparation for the upcoming corn crop.  The fall window for direct application of anhydrous ammonia in the U.S. Midwest was longer than average because of the early harvest and because soil temperature and moisture levels were essentially ideal from late October through the end of November.  When ammonia became a scarce product late in the season, CF Industries took advantage of the expanded size and flexibility of its production, logistics and terminal network to deliver product to areas of unmet demand.

In addition to very positive conditions for agricultural direct application, industrial ammonia usage was up an estimated ten percent compared to the fourth quarter of last year.  CF Industries was able to capitalize on high total demand in part because its North America production system produced at full capacity during the quarter.

“A second consecutive favorable ammonia season quickly depleted industry inventory,” said Wilson.  “Our team used this opportunity to demonstrate that we can operate our recently expanded system in a way that satisfies more customers during the peak season than CF Industries and Terra could serve separately in the past, even in the face of weather-related transportation challenges.”

CF Industries sold 662,000 tons of urea at an average price of $323 in the fourth quarter, compared to 662,000 tons at an average price of $272 in the 2009 fourth quarter.  The average realized price was 23 percent higher than the third quarter of 2010, as strong international demand offset higher supply.  Increased global availability caused by high global operating rates

and increased exports from China during the quarter was absorbed by surging demand.  Some of the price strength during the period resulted from anticipation of reduced Chinese export potential, which materialized when China announced a lengthened high-tariff period.

The company sold 1.4 million tons of UAN in the fourth quarter of 2010 at an average price of $206 per ton, compared to 494,000 tons at an average price of $156 in the year-ago quarter.  The inclusion of Terra sales accounted for most of the volume increase.  Although the average price realized for UAN sales was up ten percent from the third quarter, the increase lagged that of the other nitrogen products because more UAN volume had been committed and priced in the third quarter, early in the period of rising fertilizer prices. The UAN expansion at the company’s Woodward, Oklahoma facility did not ship any product during the fourth quarter.

In the fourth quarter, AN volume of 263,000 tons was sold at an average price of $211.  There were no AN sales in 2009 as all of the company’s AN capacity was acquired in the Terra transaction.  Strong sales volume was enabled by high production at the Yazoo City, Mississippi Nitrogen Complex, which set annual production records for ammonia, AN and urea liquor in 2010.

Total nitrogen net sales in the fourth quarter totaled $1.0 billion, up 185 percent from $352.0 million in the 2009 fourth quarter.  Gross margin for the nitrogen segment was $420.6 million, or 42 percent of sales. Excluding the unrealized mark-to-market gain of $31.4 million, gross margin was 39 percent of sales, compared to 30 percent in the year-ago period.  The increase in the percentage was due primarily to higher product prices.

CF Industries’ realized natural gas cost averaged $4.29 per MMBtu in the fourth quarter of 2010, compared to $4.34 during the fourth quarter of 2009.  Average cash prices at Henry Hub were below $4.00 per MMBtu in both October and November.  Even when weather was unusually cold during December, cash prices at Henry Hub traded no higher than $4.54/MMBtu.

The company operated its ammonia plants at capacity during the quarter.

Phosphate Fertilizer Segment

CF Industries sold 477,000 tons of diammonium phosphate (DAP) and monoammonium phosphate (MAP) during the fourth quarter of 2010 at an average price of $493 per ton.  This compares to fourth quarter 2009 shipments of 551,000 tons at an average price of $281.  Sales were limited by production and by low beginning inventories.

Strength in phosphate prices reflected tight global supply conditions and rising grain prices.  U.S. producers, collectively the world’s largest exporter of phosphates, were unable to meet high domestic demand in light of large contract commitments to India, resulting in significant phosphate imports into the U.S.  Prices were also supported by Chinese export restrictions, news of delays of new international projects and domestic production challenges.

CF Industries emphasized domestic sales of phosphates during the fourth quarter.  The company fulfilled its remaining contractual commitment to export phosphate to India with the shipment of one vessel during the quarter.

Gross margin for the segment was $63.3 million, up from $16.4 million in the 2009 fourth quarter.  Gross margin percentage was 27 percent of sales, compared to 11 percent in the year-earlier period.

CF Industries’ Plant City, Florida Phosphate Complex operated at 83 percent of capacity during the 2010 fourth quarter.

“In our phosphate business, we focused on meeting very strong domestic demand in the fourth quarter,” said Wilson.  “Production volume was the limiting factor for us as a company, as it appeared to be for the domestic industry.”

Safety Performance

The company experienced two lost-time accidents (LTAs) during the fourth quarter of 2010.  During the quarter, the Donaldsonville, Louisiana Nitrogen Complex, the largest in North America, achieved 8 years without an LTA.  Since its last LTA, the Donaldsonville Complex has completed 16 major plant turnarounds and produced over 47 million tons of nitrogen fertilizers. Also during the quarter, the Yazoo City, Mississippi nitrogen complex achieved 4 years without an LTA; the Tampa, Florida port facility achieved 6 years without an LTA and the Cowden, Illinois distribution terminal achieved 15,000 consecutive days (over 41 years) without an LTA.

Other Developments

Acquisition Integration

The integration of the former operations of Terra Industries continues to exceed expectations.  The company estimates that as of the end of 2010, implemented synergy actions totaled approximately $110 million on a run-rate basis and identified synergies exceed the top end of the targeted range.  To complete the integration of operating and financial systems, the company has initiated a project to implement an enterprise resource planning system.  The company expects to complete the project in 2012.

Said Wilson, “We are extremely pleased by our integration accomplishments in just nine months of combined operation.  Our teams have come together very well and we are serving customers with a single face to the market.”

Sale of Warehouses

In January 2011, CF Industries entered into a definitive agreement to sell four dry product warehouses and related assets to GROWMARK, Inc. and one of its subsidiaries.  Over a number of years, the company’s throughput utilization of these facilities had declined as an increasing portion of the company’s dry product volume has been shipped directly to customers from manufacturing locations.  The transaction closed on February 15, 2011.

Liquidity and Financial Position

At December 31, 2010, CF Industries’ cash, cash equivalents and short-term investments totaled $800.8 million.  In addition, the company held investments in auction rate securities (ARS) at

5

December 31, 2010 that were valued at $102.8 million. During the fourth quarter, the company received $19 million in redemptions at par.  Although there was a successful auction of ARS in the quarter, the remaining securities continue to be classified as illiquid.

CF Industries repaid $300 million of its term loan from available cash during the quarter and had repaid a total of $854 million by December 31.  At that time, the company had outstanding long term debt of $2.0 billion, comprising primarily $1.6 billion in senior notes and the remaining term loan balance of $346 million.  The company expects to retire the remaining balance of the term loan during the first quarter of 2011.

Dividend Payment

On February 2, 2011, CF Industries’ Board of Directors declared the regular quarterly dividend of $0.10 per common share.  The dividend will be paid on March 1, 2011 to stockholders of record on February 14, 2011.

Outlook

Fertilizer markets are expected to remain strong through the spring season, with high crop prices continuing to set the tone.  CF Industries expects 92 million acres of corn to be planted this spring, up nearly 4 million acres from spring of 2010 due to high expected farm profitability and a low stocks-to-use ratio.  Across the primary crops, the company expects U.S. farmed area to increase by about 10 million acres, returning to 2008 levels.

Global fertilizer supply/demand balances are expected to remain tight through the spring.  International urea trade is expected to be supported by continuing import demand in the U.S., Europe, and certain Asian markets. Urea inventories are reported to be lean in some key markets, and lower availability of Chinese product is expected to keep the balance favorable.

UAN demand is expected to benefit from robust planting seasons in North America and Europe, which should largely absorb available supplies of both UAN and AN.  Demand for AN in Europe is likely to continue to compete with U.S. demand for export-oriented UAN production, keeping the UAN market in the U.S. relatively thinly supplied.

Midwest ammonia is poised for another good season this spring.  Although volume may not reach last spring’s exceptional level, it should be strong because of excellent economics at the farm level.  CF Industries and other ammonia producers are striving to rebuild inventories after excellent back-to-back direct application seasons.

The outlook for natural gas prices continues to be favorable for nitrogen producers.  The forward strip currently is below $5.00 per MMBtu for the next 18 months.  CF Industries expects drilling activity in the lower-48 states to remain sufficiently high to maintain production at or near record levels, supported by abundant shale gas plays with low development costs and attractive economics.  Despite weather-related draws on inventory, storage levels also are expected to exit the spring at or near record levels. The combination of historically high production and storage is expected to continue pressuring prices in 2011.

Phosphate market conditions also are very favorable.  Demand in North America and Europe is expected to remain robust due to strength in commodity markets and large expected crop plantings.  In the U.S., spring demand for DAP and MAP is projected to be above the five-year average, in contrast with levels the previous two years, which were meaningfully below average.  Buyers in other markets, including India, will need to replenish phosphate inventories in the first quarter, supporting global markets.

Current tight global inventories are expected to persist through the first half of the year, leaving producers in comfortable positions with little spot availability. As with urea, diminished export availability of phosphates from China will provide additional support to world prices.  Delays to the Ma’aden, Saudi Arabia phosphate project have reduced global supplies further relative to earlier expectations.  Because CF Industries expects global phosphate demand to continue to grow at an average annual rate above four percent, the company views the Ma’aden project as a necessary addition to global capacity and believes that delays have reduced the likely impact its eventual commissioning may have on the global market.

“We believe all the factors are in place to make 2011 a great year for CF Industries,” said Wilson.  “In addition to a more complete realization of the extremely favorable fertilizer market conditions we are experiencing now, we will have the added benefit of a full year of acquisition synergies and operational integration of our expanded platform.”

The company continues to believe that business conditions are supportive of an extended period of strong cash flow.  Management projects capital expenditures of approximately $300 million in 2011, higher than 2010 because current market conditions make the expected returns for many projects favorable, cash and liquidity are ample and Terra’s first quarter 2010 spending was not included in the reported results.
