LSB Announces Oklahoma Plant Stops Ammonia Production; Will Perform Unplanned Maintenance

LSB Industries, Inc. LXU today announced that its Pryor, Oklahoma chemical facility (“Pryor Facility”) has stopped production at its principal ammonia plant to perform unplanned maintenance on a compressor. During this downtime, the Pryor Facility will also install a replacement ammonia converter, which is expected to improve the production capacity of this ammonia plant. The Company estimates an outage of approximately 6 to 8 weeks. Downtime at the Pryor Facility had been planned for January 2013 to perform the ammonia converter replacement and planned maintenance activities, but this outage began earlier and is likely to be longer than the Company previously anticipated due to the need for unplanned maintenance on the compressor. The Company estimates that the adverse effect of this downtime on operating income is approximately $2 million per week until production resumes.
