    BFC GAS COMPANY, LC; BFC Electric Company, LC, Plaintiffs-Appellants v. GYPSUM SUPPLY CO., doing business as Gypsum Supply Co. of Cedar Rapids, Defendant-Appellee.
    No. 15-1031.
    United States Court of Appeals, Eighth Circuit.
    Submitted: Dec. 7, 2015.
    Filed: Jan. 26, 2016.
    Kathryn S. Barnhill, Barnhill & Associates, West Des Moines, IA, Mark Anthony Critelli, Critelli Law Firm, PC, Urbandale, IA, for Plaintiff-Appellants.
    Philip A. Burian, Simmons & Perrine, Cedar Rapids, IA, for Defendant-Appellee.
    Before LOKEN, BOWMAN, and COLLOTON, Circuit Judges.
    [Unpublished]
   PER CURIAM.

In this diversity action involving negligence claims, BFC Gas Company and BFC Electric Company appeal from the order and judgment of the District Court excluding their expert witness opinions and granting Gypsum Supply Company’s motion for summary judgment. Following careful review, we affirm these rulings for the reasons given in the District Court’s order. See 8th Cir. R. 47B. To the extent appellants challenge the subsequent order imposing sanctions, we lack jurisdiction because appellants did not timely appeal this order. See Dieser v. Cont’l Cas. Co., 440 F.3d 920, 924 (8th Cir.2006). We deny the pending motion to supplement the record. 
      
      . The Honorable Linda R. Reade, Chief Judge, United States District Court for the Northern District of Iowa.
