granted the motion, finding that Hagerty had not pled his allegations with the requisite particularity required by Rule 9(b). On August 14, 2015, Hagerty moved for leave to file a Second Amended Complaint. Three months later, the district court denied Hagerty’s motion on the basis of undue delay.4 This appeal followed.
II. Analysis
Hagerty insists that his First Amended Complaint satisfied Rule 9(b)’s particularity requirement and, regardless of the district, court’s view- on that matter, that he should have been given leave-to file a Second Amended Complaint. We review the granting of a motion to dismiss de novo, United States ex rel. Gagne v. City of Worcester, 565 F.3d 40, 45 (1st.Cir. 2009), and the denial of a motion to amend for abuse of discretion, United States ex rel. Kelly v. Novartis Pharms. Corp., 827 F.3d 5, 10 (1st Cir. 2016) (citing United States ex rel. Poteet v. Bahler Med., Inc., 619 F.3d 104, 116 (1st Cir. 2010)).
A. The FCA and Rule 9(b)
The FCA penalizes those who present, or cause to be presented, “false or fraudulent elaim[s] for payment or approval” to the federal government. 31 U.S.C. § 3729(a)(1). Thus, fraud under the FCA has two components: the defendant must submit or cause the submission of a claim for payment to the government, and the claim for payment must itself be false or fraudulent. United States ex rel. Ge v. Takeda Pharm. Co., 737 F.3d 116, 124 (1st Cir. 2013) (“Because FCA liability attaches only to false claims, merely alleging facts related to a defendant’s alleged misconduct is not enough. Rather, a complaint based on [the FCA] must sufficiently establish that false claims were submitted for government payment as a result of the defendant’s alleged misconduct.”) (internal citations omitted).
Federal. Rule of Civil Procedure 9(b), meanwhile, requires that a complaint state these components with “particularity,” meaning relators like Hagerty must allege the.“who, what, when, where, and how of the alleged fraud.” Id. at 123 (internal citation and quotation marks omitted). Still, we have repeatedly emphasized that there is no “checklist of mandatory requirements” that each allegation in a complaint must meet to satisfy Rule 9(b), United States ex rel. Karvelas v. Melrose-Wakefield Hosp., 360 F.3d 220, 233 (1st Cir. 2004), abrogated on other grounds by Gagne, 565 F.3d at 46 n.7, and that a “somewhat ‘more flexible’ standard” applies in qui tarn actions where the defendant is alleged to have induced third parties to file false claims, Kelly, 827 F,3d at 13 (1st Cir. 2016) (quoting United States ex rel. Duxbury v. Ortho Biotech Prods., L.P., 579 F.3d 13, 29-30 (1st Cir. 2009)).
A relator can meet this more accommodating standard by “providing ‘factual or statistical evidence to strengthen the inference of fraud beyond possibility’ without necessarily providing details as to each false, claim.” Ge, 737 F.3d at 123-24 (quoting Duxbury, 579 F.3d at 29) (emphasis added). Such evidence generally includes, inter alia, the “‘specific medical providers who allegedly submitted false claims,’ the ‘rough time periods, locations, and amounts of the claims,’ and ‘the specific government programs to which the

Cyberonics alternatively argues that the district court also denied Hagerty's motion because any amendment would have been futile. Since, as we will explain, the district court's denial was justified under an undue delay analysis, we decline to consider the futility of Hagerty's proposed amendments.
