Plaintiffs are former IBM employees who entered into severance agreements in which they agreed not to join any collective actions against IBM asserting claims under the Age Discrimination in Employment Act of 1967 (“ADEA”), 29 U.S.C. §§621-634. Plaintiffs sued IBM to challenge the validity of those collective-action waivers, arguing that they were not “knowing and voluntary” because IBM failed to make certain disclosures to Plaintiffs as required for the waiver of “any right or claim” under the ADEA. 29 U.S.C. §626(f)(1). The district court (Gardephe, J.) granted IBM’s motion to dismiss for failure to state a claim, and Plaintiffs appealed. MICHAEL PARK, CIRCUIT JUDGE The result in this case follows directly from the Supreme Court’s decision in 14 Penn Plaza LLC v. Pyett, 556 U.S. 247 (2009). There, the Court held that §626(f)(1) of the ADEA applied to “substantive right[s],” like “the statutory right to be free from workplace age discrimination,” but not procedural ones, like “the right to seek relief from a court in the first instance.” Id. at 259, 265-66 (citation omitted). Collective-action waivers, like arbitration clauses, address procedural, not substantive rights, and thus do not require special disclosures under §626(f)(1) of the ADEA for their acceptance to be “knowing and voluntary.” The district court correctly held that 14 Penn Plaza governs this case and granted IBM’s motion to dismiss Plaintiffs’ complaint.

We affirm. I. BACKGROUND A. Facts In May 2016, Defendant IBM terminated Plaintiffs Steven Estle, Margaret Ahlders, Lance Salonia, and Cheryl Witmer, all of whom were 56 or 57 years old at the time, as part of a reduction in force. IBM offered a severance package to Plaintiffs that included a lump-sum payment equal to one month’s salary, six to twelve months of health and life insurance coverage, career counseling services, and reimbursement for job-related skills training. In exchange, each Plaintiff agreed to sign a separation agreement containing a collective-action waiver, which stated as follows: TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, YOU AND IBM AGREE THAT NO COVERED CLAIMS MAY BE INITIATED, MAINTAINED, HEARD, OR DETERMINED ON A MULTIPARTY, CLASS ACTION BASIS OR COLLECTIVE ACTION BASIS EITHER IN COURT OR IN ARBITRATION, AND THAT YOU ARE NOT ENTITLED TO SERVE OR PARTICIPATE AS A CLASS ACTION MEMBER OR REPRESENTATIVE, OR COLLECTIVE ACTION MEMBER OR REPRESENTATIVE, OR RECEIVE ANY RECOVERY FROM A CLASS OR COLLECTIVE ACTION INVOLVING COVERED CLAIMS EITHER IN COURT OR ARBITRATION.1 Each Plaintiff signed the separation agreement. B. Procedural History Plaintiffs sued IBM in the United States District Court for the Southern District of New York seeking a declaration that the collective-action waiver in the separation agreement is invalid under the ADEA and an injunction barring IBM from enforcing the waiver against Plaintiffs. IBM moved to dismiss for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6), and the district court granted the motion. The district court relied on 14 Penn Plaza to conclude that — “for purposes of Section 626(f) — ‘right’ means a ‘substantive right’” and, because it determined that “the right to bring a collective action is not a substantive right,” the district court held that “Plaintiffs’ collective action waiver does not waive a ‘right’ for purposes of Section 626(f)….” App’x at 39-40. Plaintiffs timely appealed. II. DISCUSSION A. Standard of Review “We review the grant of a Rule 12(b)(6) motion to dismiss de novo. We accept the factual allegations as true and draw all reasonable inferences in favor of the plaintiff.” Specht v. City of New York, 15 F.4th 594, 599 (2d Cir. 2021) (cleaned up). B. Statutory Requirements The ADEA generally prohibits employment discrimination on the basis of an employee’s age. See 29 U.S.C. §623. In 1990, Congress amended the ADEA by passing the Older Workers Benefit Protection Act (“OWBPA”), which provides that “[a]n individual may not waive any right or claim under [the ADEA] unless the waiver is knowing and voluntary.” Id. §626(f)(1). And “if a waiver is requested in connection with an exit incentive or other employment termination program offered to a group or class of employees,” the employer must provide certain information to the individual for the waiver to be “knowing and voluntary.” Id. §626(f)(1), (f)(1)(H). Specifically, this information consists of: (i) any class, unit, or group of individuals covered by such program, any eligibility factors for such program, and any time limits applicable to such program; and (ii) the job titles and ages of all individuals eligible or selected for the program, and the ages of all individuals in the same job classification or organizational unit who are not eligible or selected for the program. Id. §626(f)(1)(H)(i)-(ii). IBM did not provide Plaintiffs with this information before they signed the separation agreement containing the collective-action waiver. That waiver is enforceable, then, only if “any right or claim” in §626(f)(1) does not include the ability to initiate or participate in collective actions under the ADEA. C. 14 Penn Plaza Our analysis in this case flows directly from the Supreme Court’s decision in 14 Penn Plaza LLC v. Pyett, 556 U.S. 247 (2009). The issue there was “whether a provision in a collective-bargaining agreement that clearly and unmistakably requires union members to arbitrate claims arising under the [ADEA] is enforceable.” Id. at 251. The Court held that it was. See id. at 274. In reaching that holding, the Court rejected the respondents’ argument that a union cannot waive its members’ right to a judicial forum because “an individual employee must personally ‘waive’ a ‘[substantive] right’ to proceed in court for a waiver to be ‘knowing and voluntary’ under the ADEA.” Id. at 259 (alteration in original) (citation omitted). The Court determined that the respondents’ argument was “incorrect[],” reasoning that the “knowing and voluntary” waiver requirements of §626(f)(1) did not apply because an “agreement to arbitrate ADEA claims is not the waiver of a ‘substantive right’ as that term is employed in the ADEA.” Id. at 259 (citation omitted). The Court elaborated on the distinction between “substantive right[s]” and non-substantive, or procedural rights, as it distinguished 14 Penn Plaza from Alexander v. Gardner-Denver Co., 415 U.S. 36 (1974), which had “ erroneously assumed that an agreement to submit statutory discrimination claims to arbitration was tantamount to a waiver of those rights.” 14 Penn Plaza, 556 U.S. at 265. The Court explained that Gardner-Denver was correct in concluding that federal antidiscrimination rights may not be prospectively waived, see 29 U.S.C. §626(f)(1)(C)…but it confused an agreement to arbitrate those statutory claims with a prospective waiver of the substantive right. The decision to resolve ADEA claims by way of arbitration instead of litigation does not waive the statutory right to be free from workplace age discrimination; it waives only the right to seek relief from a court in the first instance. Id. at 265-66. The Court thus construed the phrase “right or claim” in §626(f)(1) and one of its subparts to mean “substantive right,” which includes “federal antidiscrimination rights” and “the statutory right to be free from workplace age discrimination,” as distinguished from procedural rights, like “the right to seek relief from a court in the first instance.” Id. at 259, 265-66 (citation omitted). The result in this case is governed by 14 Penn Plaza: The phrase “right or claim” as used in §626(f)(1) is limited to substantive rights and does not include procedural ones. And collective action, like arbitration, is a “procedural mechanism,” not a substantive right. Sutherland v. Ernst & Young LLP, 726 F.3d 290, 297 n.6 (2d Cir. 2013) (cleaned up) (reiterating that the “right” to proceed collectively under the Fair Labor Standards Act of 1938 (“FLSA”), see 29 U.S.C. §216(b), which the ADEA incorporates, see 29 U.S.C. §626(b), is a “procedural ‘right’”); see also Shady Grove Orthopedic Assocs., P.A. v. Allstate Ins. Co., 559 U.S. 393, 408 (2010) (plurality opinion) (holding that rules of civil procedure allowing multiple claims to be litigated together “neither change plaintiffs’ separate entitlements to relief nor abridge defendants’ rights; they alter only how the claims are processed”). A collective-action waiver is thus not a waiver of any “right or claim” under the ADEA that triggers the requirements of 29 U.S.C. §626(f)(1). Plaintiffs may still bring ADEA age discrimination claims individually, and the fact that they may not pursue them as collective actions does not mean that they have waived the substantive rights or claims themselves. Plaintiffs argue that the Supreme Court’s interpretation of §626(f)(1) in 14 Penn Plaza is nonbinding dicta. We disagree. For one, the Court’s interpretation of §626(f)(1) was essential to distinguishing its holding in 14 Penn Plaza from its earlier, incorrect dicta in Gardner-Denver, as explained above. Further, the Court’s determination that the requirements of §626(f)(1) did not apply to waivers of procedural rights was necessary to its conclusion that a collective bargaining agreement’s prospective waiver of union members’ right to bring ADEA claims in court is enforceable. If the “knowing and voluntary” waiver requirements applied to both substantive and procedural rights, the union-negotiated arbitration agreement would have been unenforceable because it was not made by the individual and it was prospective. See 29 U.S.C. §626(f)(1)(A) (“[A] waiver may not be considered knowing and voluntary unless…[it] is part of an agreement between the individual and the employer…. “); id. §626(f)(1)(C) (prohibiting “waive[r of] rights or claims that may arise after the date the waiver is executed”); 14 Penn Plaza, 556 U.S. at 259 (“[E]ven a waiver signed by an individual employee would be invalid as [§626(f)(1)] also prevents individuals from ‘waiv[ing] rights or claims that may arise after the date the waiver is executed.’” (third alteration in original) (citation omitted)).2 We see no reason to deviate from the Court’s unambiguous interpretation of §626(f)(1), which is consistent with the decision of every court of appeals to consider the issue. See Rosenberg v. Merrill Lynch, Pierce, Fenner & Smith, Inc., 170 F.3d 1, 13-14 (1st Cir. 1999); Seus v. John Nuveen & Co., 146 F.3d 175, 181-82 (3d Cir. 1998), overruled on other grounds by Green Tree Fin. Corp.-Ala. v. Randolph, 531 U.S. 79 (2000); Williams v. Cigna Fin. Advisors, Inc., 56 F.3d 656, 660-61 (5th Cir. 1995); McLeod v. Gen. Mills, Inc., 856 F.3d 1160, 1164-66 (8th Cir. 2017); Caley v. Gulfstream Aerospace Corp., 428 F.3d 1359, 1373 n.15 (11th Cir. 2005).3 D. Statutory Interpretation Finally, we are unpersuaded by Plaintiffs’ remaining arguments. Plaintiffs argue that the plain meaning of “any right or claim” in §626(f)(1) is not limited to “substantive” rights and must include collective action, which the ADEA “explicitly identifies” as a right. Appellants’ Reply Br. at 16. They point to 29 U.S.C. §626(b), which incorporates a provision of the FLSA providing that ” [a]n action to recover the liability prescribed [under the FLSA] may be maintained against any employer…by any one or more employees for and in behalf of himself or themselves and other employees similarly situated.” 29 U.S.C. §216(b). That same subsection then states that “[t]he right provided by this subsection to bring an action by or on behalf of any employee, and the right of any employee to become a party plaintiff to any such action, shall terminate upon the filing of a complaint by the Secretary of Labor.” Id. Plaintiffs’ argument based on the ADEA’s apparent endorsement of a right to collective action is unpersuasive. After all, the ADEA also identifies a right to a jury trial. See 29 U.S.C. §626(c)(2) (“a person shall be entitled to a trial by jury”); Lehman v. Nakshian, 453 U.S. 156, 162 (1981), superseded by statute on other grounds, 42 U.S.C. §1981A(c)(1) (stating that §626(c) provides a “statutory right to a jury trial”). Nevertheless, the Court in 14 Penn Plaza construed “right or claim” in §626(f)(1) as referring to substantive rights and concluded that they did not include the right to a judicial forum and hence did not include a right to a jury trial. See 556 U.S. at 259, 265-66. To the extent that the ADEA also identifies a collective-action right, Plaintiffs fail to explain why it should be treated differently from the right to a jury trial. Plaintiffs’ appeal to legislative purpose is likewise unavailing. Plaintiffs have pointed to nothing in the legislative history showing a clear intention of Congress that would support a result other than the one we reach here. III. CONCLUSION For the reasons set forth above, the district court’s judgment is affirmed.4 Dated: January 20, 2022
