Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, the Company may become involved in various lawsuits and legal proceedings, which arise in the ordinary course of business. However, litigation is subject to inherent uncertainties, and an adverse result in these, or other matters, may arise from time to time that may harm the Company’s business. On August 18, 2023, a shareholder filed a putative securities class action against the Company and certain of its current and former executive officers in the U.S. District Court for the Eastern District of Pennsylvania (the “Court”), captioned O’Meara v. Shift4 Payments, Inc., et al., Case No. 5:23-cv-03206-JFL (the “O’Meara Action”). Plaintiff O’Meara seeks to represent purchasers of the Company’s securities between November 10, 2021 and April 18, 2023. On October 13, 2023, another shareholder represented by the same law firm as O’Meara filed a similar complaint against the same defendants in the Court, captioned Baer v. Shift4 Payments, Inc., et al., Case No. 5:23-cv-03969-JFL (the “Baer Action”). Plaintiff Baer seeks to represent purchasers of the Company’s securities between June 5, 2020, and April 18, 2023. Both complaints allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, based on allegedly false and misleading statements about the Company’s business, operations, and compliance policies, and both seek unspecified damages. On October 19, 2023, Plaintiff Baer filed a motion to consolidate the O’Meara Action and the Baer Action and appoint Baer as lead plaintiff. On November 3, 2023, the Court consolidated the O’Meara and Baer Actions and appointed Plaintiff Baer as the lead plaintiff in the consolidated action. Lead Plaintiff Baer and Plaintiff O’Meara filed an amended complaint on January 5, 2024, purportedly brought on behalf of purchasers of the Company’s securities between June 5, 2020 and April 18, 2023, and alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, based on allegedly false and misleading statements about the Company’s business, operations, and compliance policies. The Company moved to dismiss the consolidated amended complaint on February 19, 2024. The Court granted the Company’s motion to dismiss on August 14, 2024, with leave to amend. Lead Plaintiff Baer filed a second amended complaint on September 3, 2024, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder purportedly on behalf of purchasers of the Company’s securities between June 5, 2020 and October 21, 2022. The Company filed a motion to dismiss on October 1, 2024. A hearing is not yet scheduled on the Company’s motion to dismiss. The Company disputes the allegations in the above-referenced matters, intends to defend the matters vigorously, and believes that the claims are without merit. Certain legal and regulatory proceedings, such as the above-referenced matters, may be based on complex claims involving substantial uncertainties and unascertainable damages. Accordingly, it is not possible to determine the probability of loss or estimate damages for any of the above matters, and therefore, the Company has not established reserves for any of these proceedings. When the Company determines that a loss is both probable and reasonably estimable, the Company records a liability, and, if the liability is material, discloses the amount of the liability reserved. Given that such proceedings are subject to uncertainty, there can be no assurance that such legal proceedings, either individually or in the aggregate, will not have a material adverse effect on our business, results of operations, financial condition or cash flows. The Company is currently not aware of any legal proceedings or claims other than those described above that the Company believes could have a material adverse effect on its business, financial condition or operating results.
