Federal inmate Rodney Brown appeals *768 the district court’s 1 dismissal of his pro se motion for a sentence reduction pursuant to 18 U.S.C. § 3582(c)(2). Upon careful de novo review, see United States v. Long, 757 F.3d 762, 763 (8th Cir. 2014) (standard of review), we conclude that dismissal was proper because Brown was sentenced based on a binding plea agreement that included a base offense level and drug quantity, but did not include a criminal history level or Guidelines range, and thus was not expressly based on a Guidelines range that was subsequently lowered by the Sentencing Commission, see Freeman v. United States, 564 U.S. 522, 131 S.Ct. 2685, 2695-700, 180 L.Ed.2d 519 (2011) (So-tomayor, J., concurring); Long, 757 F.3d at 764.

Accordingly, we affirm. See 8th Cir. R. 47B.
