PER CURIAM.
Jermaine Edison pled guilty pursuant to a written plea agreement to one count of conspiring to distribute cocaine, cocaine base ("crack cocaine") and Ecstasy in violation of 21 U.S.C. §§ 841(b)(1)(B) and 846. He now appeals his below-guideline sentence of 176 months. Edison contends the sentence is substantively unreasonable and greater than necessary to achieve the statutory goals of sentencing. Having jurisdiction under 18 U.S.C. § 3742 and 28 U.S.C. § 1291, we affirm.
In February 2012, a confidential source told law enforcement Edison was distributing cocaine and crack cocaine. As a result, on February 14, 2012, law enforcement made a controlled purchase of approximately 25.3 grams of crack cocaine from Edison. Between that date and August 16, 2012, law enforcement set up a total of six controlled purchases of cocaine and Ecstasy. The purchases were set up by contacting Edison, who would either provide the controlled substances himself or refer the confidential source to his codefendant, Antoine Kenyetta Poole. In addition, on May 9, 2012, law enforcement in Los Angeles, California, intercepted two packages containing a total of $18,000 in cash that Edison had mailed to California.
On September 11, 2012, Edison and Poole were both charged in the United States District Court for the District of Minnesota with a number of drug offenses. Edison eventually pled guilty to conspiracy to distribute 500 grams or more of cocaine, 28 grams or more of crack cocaine, and a quantity of Ecstasy, from on or about February 14, 2012, through on or about August 16, 2012, in violation of 21 U.S.C. §§ 841(b)(1)(B) and 846. In his written plea agreement, Edison stipulated that the relevant drug quantity attributable to him was "at least 500 grams of cocaine, as well as a quantity of cocaine base and a quantity of Ecstasy"; that he faced a 10-year mandatory minimum sentence due to a qualifying prior drug conviction; and that he qualified as a career offender for purposes of the sentencing guidelines.
At sentencing, the district court
"This court reviews sentences in two steps: first, for significant procedural error; and if there is none, for substantive reasonableness." United States v. Williams, 624 F.3d 889, 896 (8th Cir.2010) (citation omitted). Edison does not allege procedural error, only that the sentence was substantively unreasonable. We review the substantive reasonableness of the district court's sentence under an abuse of discretion standard. Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). "A district court abuses its discretion when it (1) fails to consider a relevant factor that should have received significant weight; (2) gives significant weight to an improper or irrelevant factor; or (3) considers only the appropriate factors but in weighing those factors commits a clear error of judgment." United States v. Borromeo, 657 F.3d 754, 756 (8th Cir.2011) (quoting United States v. Feemster, 572 F.3d 455, 461 (8th Cir.2009) (en banc)). When a district court's sentence is below the applicable guideline range, "`it is nearly inconceivable that the court abused its discretion in not varying downward still further.'" United States v. McKanry, 628 F.3d 1010, 1022 (8th Cir.2011) (quoting United States v. Moore, 581 F.3d 681, 684 (8th Cir.2009)).
Edison also argues the district court erred in sentencing him to a 176-month term of imprisonment because his codefendant, Poole, received a 72-month sentence; he asserts this resulted in an unwarranted sentencing disparity. However, Poole was not a career offender and did not face a statutory 10-year mandatory minimum sentence based on a prior qualifying drug conviction. Therefore, Edison and Poole were not similarly situated, and the disparity between their sentences was not unwarranted. See United States v. Maxwell, 664 F.3d 240, 245 (8th Cir.2011) ("Sentencing disparities are not unwarranted when there are legitimate distinctions between codefendants.") (citation omitted).
For the foregoing reasons, we affirm.
