Feb 19 (Reuters) - Fertilizer firm CF Industries ( CF )

posted an increase in its fourth-quarter profit on Wednesday,

helped by higher ammonia sales and steady prices.

The company said ammonia sales volumes rose on the back of

contractual commitments served from the acquisition of the

Waggaman ammonia production facility in December 2023.

Quarterly net sales of its ammonia segment, which produces

anhydrous ammonia, were up at $572 million, from $495 million a

year earlier.

The Northbrook, Illinois-based company reported a net income

of $328 million, or $1.89 per share, for the three months ended

December 31, compared with $274 million, or $1.44 per share,

last year.
