Calumet Announces First Quarter 2026 Operational Update

INDIANAPOLIS, April 2, 2026 /PRNewswire/ -- Calumet, Inc. (NASDAQ: CLMT) ("Calumet" or the "Company") announced today an operational update for the first quarter of 2026.

Shreveport Maintenance

Late in the first quarter, our Shreveport facility required unplanned maintenance after discovering the presence of organic chlorides¹ in our feedstock tanks. Operations across significant portions of the facility were temporarily suspended to protect our employees and equipment. This outage resulted in a loss of approximately 750,000 barrels of production, and the Company, assisted by third party experts, are conducting an investigation as to the source of organic chlorides.  After extensive product testing, asset inspection, and equipment repairs, the Shreveport facility is back fully operational and processing over 50,000 barrels per day of feedstock. 

Montana Renewables Expansion

As previously disclosed, Montana Renewables (MRL) planned shutdown for its MaxSAF^® expansion and additional turnaround activities began the week of March 2nd and is expected to last approximately 48 days. The project is more than 70% complete and is currently on time and budget.
