MP Materials' fourth-quarter loss widens on higher production costs

Feb 20 (Reuters) - Rare earths producer MP Materials MP.N said on Wednesday its fourth-quarter loss widened due in part to higher production costs for the refining of the minerals.

The Las Vegas-based company reported a net loss for the period ended December 31 of $22.3 million, or 14 cents per share, compared to a net loss of $16.3 million, or 9 cents per share, in the year-ago quarter.
