    Before NIEMEYER, KING, and DUNCAN, Circuit Judges.
   Unpublished opinions are not binding precedent in this circuit.

PER CURIAM:

Kyjahre Hasan Riley seeks to appeal the district court’s amended judgment, resen-tencing him to a period of incarceration of “37 months but not less than time served.” United States v. Riley, No. 1:12-cr-00060-WO-1 (M.D.N.C., PACER No. 70 at 2). Because Riley has completed his term of imprisonment, we dismiss Riley’s appeal as moot.

Although neither party questions whether Riley’s appeal of his term of imprisonment is moot, this court “must address whether [it has] jurisdiction over this ... appeal.” Yates v. Terry, 817 F.3d 877, 882 (4th Cir. 2016). “The doctrine of mootness originates in Article Ill’s case or controversy language,” and this Court loses jurisdiction over any portion of an appeal that becomes moot. Incumaa v. Ozmint, 507 F.3d 281, 286 (4th Cir. 2007) (alterations and internal quotation marks omitted). “[A] case is moot when the issues presented are no longer live or the parties lack a legally cognizable interest in the outcome.” Id. (internal quotation marks omitted). “If an event occurs while a case is pending on appeal that makes it impossible for the court to grant any effectual relief whatever to a prevailing party, the appeal must be dismissed....” Id. (alteration and internal quotation marks omitted).

. Here, Riley’s completion of his term of imprisonment before his appeal rendered his. challenge to the prison term moot. Accordingly, we dismiss Riley’s appeal for lack of jurisdiction. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

DISMISSED
