Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Sherwin Timothy Farmer seeks to appeal the district court’s order denying his *497 motion for reduction of sentence under 18 U.S.C. § 3582(c)(2) (2006). In criminal cases, the defendant must file the notice of appeal within ten days after the entry of judgment. Fed. R.App. P. 4(b)(1)(A); see United States v. Alvarez, 210 F.3d 309, 310 (5th Cir. 2000) (holding that § 3582 proceeding is criminal in nature and ten-day appeal period applies). With or without a motion, upon a showing of excusable neglect or good cause, the district court may grant an extension of up to thirty days to file a notice of appeal. Fed. R.App. P. 4(b)(4); United States v. Reyes, 759 F.2d 351, 353 (4th Cir. 1985).

The district court entered its order denying the motion for reduction of sentence on March 3, 2008. The notice of appeal was filed on March 24, 2009. Because Farmer failed to file a timely notice of appeal or to obtain an extension of the appeal period, we dismiss the appeal. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED.
