*1 Before: GOODWIN, FARRIS, and FERNANDEZ, Circuit Judges.

Thomas Edward King, Jr., appeals pro se from the district court’s judgment dismissing for failure to prosecute his 42 U.S.C. § 1983 action alleging federal and state law claims. We have jurisdiction under 28 U.S.C. § 1291. We review for an abuse of discretion. Al-Torki v. Kaempen , 78 F.3d 1381, 1384 (9th Cir. 1996). We *2 affirm.

King failed to challenge the district court’s dismissal of his action for failure to prosecute, and has therefore waived any such challenge. See Smith v. Marsh , 194 F.3d 1045, 1052 (9th Cir. 1999) (“[O]n appeal, arguments not raised by a party in its opening brief are deemed waived.”); see also Greenwood v. FAA , 28 F.3d 971, 977 (9th Cir. 1994) (“We will not manufacture arguments for an appellant . . . . ”).

Even if King had not waived his challenge, the district court did not abuse its discretion in dismissing King’s action for failure to prosecute because King failed to file an amended complaint despite receiving an extension of time to do so and being warned of the consequences of failing to file it. See Pagtalunan v. Galaza , 291 F.3d 639, 642-43 (9th Cir. 2002) (discussing the five factors for determining whether to dismiss for failure to prosecute).

We do not consider arguments and allegations raised for the first time on appeal. See Padgett v. Wright , 587 F.3d 983, 985 n.2 (9th Cir. 2009).

AFFIRMED.
