CF Industries Holdings, Inc. today reported first quarter 2011 net earnings attributable to common stockholders of $282.0 million, or $3.91 per diluted share, compared to a loss of $4.4 million, or $0.09 per diluted share, in the first quarter of 2010.  First quarter results included a $32.5 million pre-tax gain on the sale of four dry product warehouses, $19.9 million of accelerated amortization of loan costs related to retirement of the bank term loan, $2.1 million in restructuring and integration costs and a $0.7 million non-cash mark-to-market gain on natural gas derivatives.   These items increased/(reduced) after-tax earnings per diluted share by $0.28, $(0.17), $(0.02) and less than $0.01, respectively. First quarter 2010 results included $136.1 million in business combination costs, a $28.3 million gain on the sale of common shares of Terra Industries Inc., an $11.2 million non-cash mark-to-market loss on natural gas derivatives and $2.7 million of Perú project development costs.

Earnings before interest, taxes, depreciation and amortization were $585.1 million in the first quarter of 2011, compared to $19.4 million in the first quarter of 2010.

Net sales in the first quarter of 2011 were $1.2 billion, up 134 percent from $502.4 million in the same period last year, due to the inclusion of Terra net sales and higher product prices.  Year-ago volumes, sales and all other first quarter 2010 financial data in this release are presented on a pre-acquisition basis, as reported.  Reflecting this basis, total sales volume nearly doubled from 1.7 million tons in the 2010 first quarter to 3.3 million tons in 2011, largely explained by the inclusion of Terra sales volume.

“We entered the year with lean inventories,” said Stephen R. Wilson, chairman and chief executive officer, CF Industries Holdings, Inc. “We are pleased that excellent plant performance allowed us to deliver good sales results in the first quarter and to position inventories for the spring selling season.”

The company reported record first quarter revenue, net earnings and earnings per share.  Cash flow from operations was the highest of any quarter in the company’s history due to the strong earnings and a net addition to customer deposits related to forward sales.  Continued Wilson, “Industry conditions presented a great opportunity for us to showcase CF Industries’ earnings power.  Our capable, integrated team seized that opportunity, operating our assets effectively and taking advantage of our expanded set of tools and market expertise.  As a result, the acquisition synergies we’ve been working hard to implement were visible at the bottom line.”

Expectations for the spring selling season are high, with the U.S. Department of Agriculture (USDA) forecasting that farmers will plant 92 million acres of corn, 58 million acres of wheat and 13 million acres of cotton this crop year.  Planting started somewhat early in the southern plains, except in drought-stricken areas, principally in Texas.  However, poor weather in the Corn Belt has delayed nutrient application and planting and has caused flooding, which complicates logistics.

Flexibility in plant sourcing and transportation has continued to benefit CF Industries and its customers during the period of high water levels on the inland waterway system.  The company’s

2

scale, geographic scope and access to a variety of transportation modes allow it to react quickly to customer needs by varying production sources and distribution methods.

Grain prices remain high, providing farmers with compelling incentives to plant corn, wheat and cotton and to fertilize them optimally.  Even with elevated corn prices, demand destruction has not been evident.  With projected corn usage providing little relief to the very low stocks-to-use ratio, farmers appear to be following through on spring planting intentions where possible and planning for large plantings in future years.

Nutrient prices continue to be favorable, with ammonia and UAN prices rising during the first quarter and phosphate prices maintaining high levels.  International urea values declined in March, but subsequently rebounded.

Nitrogen Segment

CF Industries delivered 2.8 million tons of ammonia, urea, urea ammonium nitrate solutions (UAN), ammonium nitrate (AN) and other nitrogen products during the first quarter of 2011.

Ammonia sales volume in the first quarter of 2011 of 410,000 tons was sold at an average price of $494 per ton, compared to 189,000 tons at an average price of $321 in the first quarter of 2010.  The 54 percent increase in average price realizations reflected much higher market prices, offset partially by a seasonally low agricultural portion of the ammonia mix in the first quarter, an effect that was less pronounced before the Terra acquisition.  All seven of the company’s nitrogen fertilizer manufacturing complexes in North America operated at full ammonia production capacity in the quarter.

CF Industries sold 604,000 tons of granular urea at an average price of $371 in the 2011 first quarter, compared to 598,000 tons at an average price of $306 in the 2010 first quarter.  After increasing steadily since summer, urea prices declined in March due to high global production rates, greater than expected exports from China in December and January, and delayed purchases by India.  In this environment, and in light of heightened political uncertainty, traders increased imports into the U.S., the world’s most liquid market for plant nutrients.  However, low beginning stocks and heavy farm-level demand allowed the domestic market to absorb the higher levels of imports.

The company sold about 1.5 million tons of UAN in the first quarter of 2011 at an average price of $277 per ton, compared to 404,000 tons at an average price of $205 in the year-ago quarter.  The start-up of the new Woodward, Oklahoma UAN plant helped the company achieve record quarterly production of nearly 1.6 million tons (32 percent basis).  Customer shipments of UAN were 17 percent higher than the pro forma combined volume of CF Industries and Terra in the first quarter of 2010.  Notwithstanding heavy industry shipping volume in the first quarter, the company believes that UAN’s current larger than normal price premium on a nutrient basis compared to ammonia and urea is likely to be sustained by increasing customer preference for UAN, the likelihood of a weather-related shift from ammonia, and reduced international production of UAN.

In the first quarter of 2011, AN sales volume of 244,000 tons was sold at an average price of $251.  There were no AN sales in the first quarter of 2010 as all of the company’s AN capacity was acquired in the Terra transaction. AN production of 283,000 tons was the highest quarterly level since the acquisition.

CF Industries’ nitrogen sales also included 129,000 tons of other nitrogen products, including 71,000 tons of urea liquor (UL).  In previous quarterly reports, UL sales volumes have been included with granular urea.

Nitrogen net sales totaled $925.9 million, up 183 percent from $327.0 million in the 2010 first quarter.  Gross margin for the nitrogen segment was $442.5 million, more than four times the gross margin of $97.3 million in the 2010 first quarter.  The increase was due primarily to the benefit from the Terra acquisition, higher selling prices, lower realized natural gas costs and non-recurrence of an unrealized mark-to-market loss on natural gas derivatives in the prior period.  Gross margin as a percent of sales was 48 percent, up from 30 percent in the year-earlier quarter.

CF Industries’ realized natural gas cost averaged $4.32 per MMBtu in the first quarter of 2011, compared to $5.13 during the first quarter of 2010.  The winter of 2010-2011 was the fourth coldest winter in the last 25 years for the contiguous United States, drawing approximately 400 billion cubic feet (BCF) of natural gas above normal heating season demand.  It followed the second hottest summer in the same period, which drew an additional 250 BCF of natural gas above normal cooling season demand.  Despite these heavy draws, the amount of gas in storage remains above the five-year average and prices remain subdued due to high production levels.

Phosphate Segment

The phosphate segment also benefited from excellent plant performance, tying the segment’s quarterly production record as measured in tons of P2O5.  This production level allowed the company to increase domestic sales volume slightly compared to the year-earlier quarter and build inventories for spring application and opportunistic exports.  Total sales volume for diammonium phosphate (DAP) and monoammonium phosphate (MAP) was eight percent lower than in the first quarter of 2010 when beginning inventories were larger.  The phosphate sales team achieved high average price realizations by emphasizing domestic sales volume, which was higher than during the 2010 first quarter, and nimbly pursuing niche export opportunities.

Phosphate imports into the United States during the first quarter set an all-time record, which offset lower production by some domestic producers in the period.  Subsequent to the end of the quarter, one of the company’s non-integrated domestic competitors permanently ceased production of phosphates.

First quarter net sales of DAP and MAP were $248.1 million, up 41 percent from the first quarter of 2010 due to higher average selling prices.  Average price realizations for DAP and MAP were $562 and $569 per ton, compared to $361 and $379, respectively, in the year-ago period.

Gross margin for the segment was $82.5 million, up from $31.7 million in the 2010 first quarter.  Gross margin percentage was 33 percent of sales, compared to 18 percent of sales in the year-

4

earlier period.  The increase was attributable to higher prices, partially offset by higher raw materials costs.

CF Industries’ Plant City, Florida Phosphate Complex operated at 99 percent of capacity during the 2011 first quarter.

Safety Performance

As previously reported, an accident at the Hardee Phosphate Complex during February resulted in a fatal injury to a construction contractor’s employee.  Additionally, one lost time accident (LTA) affected a CF Industries employee in January.

The following company facilities achieved safety milestones during the first quarter of 2011:

·                  The Frankfort, Illinois Terminal achieved 15,000 days without an LTA;

·                  The Ritzville, Washington Terminal achieved 10,000 days without an LTA;

·                  The Courtright, Ontario Nitrogen Complex achieved ten years without an LTA;

·                  The Donaldsonville, Louisiana Nitrogen Complex achieved five million work hours (approximately eight and a half years) without an LTA; and

·                  The Port Neal, Iowa Nitrogen Complex achieved two years without an LTA.

“Our Frankfort Terminal is the eighth CF Industries facility to achieve 15,000 safe days, which is more than 41 years,” said Wilson.  “We are very proud of the deeply rooted safety culture our team exhibits each day in our workplaces.”

Liquidity and Financial Position

At March 31, 2011, CF Industries’ cash, cash equivalents and short-term investments totaled $1.1 billion, including $748 million of customer advances.  In addition, the company held investments in illiquid auction rate securities that were valued at $103.6 million.

CF Industries repaid the remaining $346 million of its term loan from available cash flow during the quarter.  The company retired the $1.2 billion term loan facility in under a year, primarily from operating cash flow.  At March 31, 2011, the company had outstanding long-term debt of $1.6 billion, comprising primarily senior notes due in 2018 and 2020.

Dividend Payment

On April 29, 2011, CF Industries’ board of directors declared the regular quarterly dividend of $0.10 per common share. The dividend will be paid on May 27, 2011 to stockholders of record on May 16, 2011.

Outlook

The company’s outlook is very positive.  Low domestic and global grain stocks are expected to drive high plantings for the next several years.  The USDA projects that U.S. farmers will plant more than 90 million acres of corn each year through 2015, which would provide a very supportive demand environment for the company’s products.

The short-term outlook also is favorable due to high expected plantings and nutrient application rates.  In some areas of the Corn Belt, direct application of ammonia started on time, but

5

subsequently was slowed by wet weather.  Delayed planting and wet soil conditions could impact farmers’ choice of nitrogen products, reducing the ammonia portion of the mix in favor of UAN and urea compared to the ideal spring ammonia season of 2010.

North American farmers are recognizing the benefits of UAN, which increases application flexibility and facilitates earlier planting.  The company expects robust UAN demand in the second quarter, which will benefit CF Industries given its strong market position for this product.  The company is taking advantage of its industry-leading flexibility in transportation and logistics to reposition its products for optimal coverage during the late, but still very promising, spring.

High demand, the narrower export window in China, gas limitations at some facilities and delays in certain scheduled capacity additions are expected to keep world ammonia and urea supply and demand balanced to tight.  The company expects global ammonia demand and prices to continue to receive support from rising industrial demand and high phosphate production rates.  Phosphate prices continue to benefit from high demand and new project delays.

The company’s position in the nitrogen market also stands to benefit from relatively stable, attractive natural gas costs in North America and higher energy prices in Europe and Asia.  Spot natural gas prices in Europe have risen due to expected higher demand for liquefied natural gas (LNG) in Japan, and oil-based contract prices have reached $13 per MMBtu in some countries that buy gas from Russia without formula discounts.  In China, higher energy prices also have raised local production costs for urea.

“Under current industry conditions we believe that CF Industries will enjoy an extended period of strong profitability,” said Wilson.  “In the short term, we are positioned for a very good spring.  Longer term, the combination of tight grain markets, the favorable cost position of North American nitrogen producers, and our unmatched flexibility in product movement make us very optimistic.”

The company expects capital expenditures of approximately $300 million in 2011.
