A district court's "decision to alter or amend judgment is committed to the sound discretion of the district judge and will not be overturned on appeal absent an abuse of discretion." Lawson v. Singletary, 85 F.3d 502, 507 (11th Cir. 1996) (per curiam) (quoting Am. Home Assurance Co. v. Glenn Estess Assocs., Inc., 763 F.2d 1237, 1238-39 (11th Cir. 1985)). A district court's denial of a motion for leave to amend is reviewed under the same abuse of discretion standard. See Laurie v. Ala. Court of Criminal Appeals, 256 F.3d 1266, 1269(11th Cir. 2001).
We review denials of Rule 59(e) motions for an abuse of discretion. Thomas v. Farmville Mfg. Co., 705 F.2d 1307, 1307 (11th Cir.1983) (per curiam). The district court's denial of the Rule 59(e) motion based on a miscomprehension of the law was an abuse of discretion. United States v. Merrill, 513 F.3d 1293, 1301 (11th Cir.2008). However, we affirm the denial on the merits. See Parks v. City of Warner Robins, 43 F.3d 609, 613 (11th Cir.1995) (“[W]e may affirm the district court's decision on any adequate ground, even if it is other than the one on which the court actually relied.”).
