Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Obligations In the ordinary course of business, the Company issues purchase orders based on its current manufacturing needs. As of September 30, 2022, the Company had non-cancelable purchase commitments of $186.9 million, of which $115.9 million are expected to be paid within the year ending December 31, 2022. Ransomware Incident On May 4, 2022, the Company determined that certain of its information technology systems were affected by ransomware impacting certain internal systems. Upon detecting the security event, the Company took immediate steps designed to contain the incident and implement its business continuity plans to restore and support continued operations. The Company has contained the incident and restored substantially all of its critical information technology systems. During the three months ended September 30, 2022, the Company incurred $1.0 million of expenses related to the ransomware incident, and during the nine months ended September 30, 2022, the Company incurred $13.5 million of expenses related to the ransomware incident, partially offset by $11.1 million of expected insurance recoveries. Expenses include costs to investigate and remediate the ransomware incident, as well as legal and other professional services, all of which were expensed as incurred. For the three and nine months ended September 30, 2022, the Company included net expenses related to the ransomware incident in cost of revenues of $0.1 million and $0.3 million, respectively; in research and development of $0.2 million and $0.2 million, respectively; and in selling general and administrative expenses of $0.7 million and $1.9 million, respectively, in the Company’s Condensed Consolidated Statements of Operations. Legal Proceedings The Company is currently involved in various legal proceedings. A class action lawsuit was filed against the Company, on June 5, 2019, in the Circuit Court of Cook County, Illinois, Chancery Division, captioned Corey Heard, individually and on behalf of all others similarly situated v. Omnicell, Inc., Case No. 2019-CH-06817 (the “Heard Action”). The complaint seeks class certification, monetary damages in the form of statutory damages for willful and/or reckless or, in the alternative, negligent violation of the Illinois Biometric Information Privacy Act (“BIPA”), and certain declaratory, injunctive, and other relief based on causes of action directed to allegations of violation of BIPA by the Company. The complaint was served on the Company on June 13, 2019. On July 31, 2019, the Company filed a motion to stay or consolidate the case with the action Yana Mazya, et al. v. Northwestern Lake Forest Hospital, et al., Case No. 2018-CH-07161, pending in the Circuit Court of Cook County, Illinois, Chancery Division (the “Mazya Action”). The Court subsequently, on October 10, 2019, denied the motion, without prejudice, as being moot in view of the dismissal of the claims against the Company in the Mazya Action. The Company filed a motion to dismiss the complaint in the Heard Action on October 31, 2019. The hearing on the Company’s motion to dismiss was held on September 2, 2020. The Court ruled from the bench and dismissed the complaint without prejudice giving plaintiff leave to file an amended complaint by September 30, 2020. Plaintiff filed an amended complaint on September 30, 2020 and the Company subsequently filed a motion to dismiss the amended complaint on October 28, 2020, which was fully briefed, but the Court had not heard oral argument on the motion. The parties entered into a settlement agreement on January 25, 2022, (the “Settlement Agreement”). On February 1, 2022, the Court granted preliminary approval of the settlement. Following preliminary approval, plaintiff conducted discovery to identify class members and to determine the class size. Pursuant to the terms of the Settlement Agreement, and following class size discovery, the parties will participate in non-binding mediation, which is currently scheduled for November 21, 2022 to determine if the settlement will move forward. The Court has scheduled an interim status conference for November 30, 2022. Subject to final approval of the settlement, the Company intends to defend the lawsuit vigorously. As required under ASC 450, Contingencies, the Company accrues for contingencies when it believes that a loss is probable and that it can reasonably estimate the amount of any such loss. The Company has not recorded any material accrual for contingent liabilities associated with the legal proceeding described above based on its belief that any potential material loss, while reasonably possible, is not probable. Further, any possible range of loss in this matter cannot be reasonably estimated at this time or is not deemed material. The Company believes that it has valid defenses with respect to the legal proceeding pending against it. However, litigation is inherently unpredictable, and it is possible that cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of the legal proceeding or because of the diversion of management’s attention and the creation of significant expenses.
