Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation and Regulatory Matters From time to time, claims and suits arise in the ordinary course of the Company’s business. The Company has been, is currently, and may in the future be subject to claims, lawsuits, qui tam actions, civil investigative demands, subpoenas, investigations, audits and other inquiries related to its operations. In certain of these actions, plaintiffs request punitive or other damages against the Company that may not be covered by insurance. These claims, lawsuits, and proceedings are in various stages of adjudication or investigation and involve a wide variety of claims and potential outcomes. Depending on whether the underlying conduct in these or future inquiries or investigations could be considered systemic, their resolution could have a material adverse effect on the Company’s results of operations, financial position or liquidity. The Company records accruals for such contingencies to the extent that the Company concludes it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. If the Company is party to any proceeding that, either individually or in the aggregate, is probable or reasonably possible of having a material, adverse effect on its results of operations, financial position, or liquidity, the Company discloses a summary of such contingencies including the amount or range of reasonably possible losses in excess of recorded amounts or that management is unable to reasonably estimate the amount or range of possible losses. Apart from ongoing litigation related to the Company's professional liability claims described in Note 11, Self-Insured Liabilities, and ongoing securities litigation and derivative action described below, management does not believe that the Company is party to any proceeding that, either individually or in the aggregate, could have a material adverse effect on its business, financial condition, results of operations or liquidity. However, in light of the inherent uncertainties involved, it is possible that the settlement of unresolved claims could have a material adverse impact on the Company's future results of operations, financial position, or liquidity. Securities Litigation On January 7, 2026, a purported stockholder filed a putative securities class action against the Company and certain current officers in the lawsuit styled Postiwala v. Ardent Health, Inc., et al., Case No. 3:26-cv-00022, which is pending in the United States District Court for the Middle District of Tennessee, Nashville Division. The complaint is brought on behalf of a putative class consisting of all persons (other than defendants) who purchased Company securities between July 18, 2024 and November 12, 2025, and alleges that defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b-5 promulgated thereunder based on allegedly false and misleading statements and omissions. Specifically, the complaint alleges that the Company incorrectly accounted for and reported on certain accounts receivable and certain insurance reserves during 2024 and 2025 which caused its stock price to be inflated. The complaint seeks unspecified monetary damages, recovery of fees and costs, and other relief that the court may find appropriate. The Company intends to vigorously defend the claims made; however, currently no assessment can be made as to the likely outcome. At this time, the Company is not able to reasonably estimate the amount or range of the ultimate liability, if any, in connection with this case. Derivative Action On February 26, 2026, a shareholder derivative action styled Thompson v Sotir, et al, Case No 3:26-cv-00219 was filed in the United States District Court for Middle District of Tennessee, Nashville Division, against certain current officers and directors. The Company is named as a nominal defendant only. The factual basis of the complaint is largely the same as in the Postiwala case mentioned above but includes some additional allegations. The complaint alleges breaches of fiduciary duties, gross mismanagement, waste of corporate assets, unjust enrichment, and violation of Section 14(a) of the Securities Exchange Act of 1934. The complaint seeks unspecified monetary damages, restitution, the adoption of certain governance reforms, recovery of fees and costs, and other relief that the court may find appropriate. The Company intends to vigorously defend the claims made; however, currently no assessment can be made as to the likely outcome. At this time, the Company is not able to reasonably estimate the amount or range of the ultimate liability, if any, in connection with this case. Cybersecurity Incident Litigation In November 2023, the Company determined that a ransomware cybersecurity incident had impacted and disrupted a number of the Company’s operational and information technology systems (the “Cybersecurity Incident”). During this time, the Company’s hospitals remained operational and continued to deliver patient care utilizing established downtime procedures. The Company immediately suspended user access to impacted information technology applications, executed cybersecurity protection protocols, and took steps to restrict further unauthorized activity. Additionally, because of the time taken to contain and remediate the Cybersecurity Incident, online electronic billing systems were not functioning at their full capacities and certain billing, reimbursement and payment functions were delayed, which had an adverse impact on the Company’s results of operations and cash flows for 2023 and the first quarter of 2024. As a result of the Cybersecurity Incident, three putative class actions were filed against the Company in the U.S. District Court for the Middle District of Tennessee: Burke v. AHS Medical Holdings LLC, No. 3:23-cv-01308; Redd v. AHS Medical Holdings, LLC, No. 3:23-cv-01342; and Epperson v. AHS Management Company, Inc., No. 3:24-cv-00396. These cases were consolidated by the District Court on April 24, 2024, under the caption Hodge v. AHS Management Company, Inc., No. 3:23-cv-01308 (M.D. Tenn.). The complaint for the consolidated class action, filed on behalf of approximately 38,000 individuals who alleged their personal information and protected health information were affected by the Cybersecurity Incident, generally asserted state common law claims of negligence, breach of implied contract, unjust enrichment, breach of fiduciary duty, and invasion of privacy with respect to how the Company managed sensitive data. On October 4, 2024, the Company executed a settlement agreement to resolve the consolidated class action litigation. On October 9, 2024, the District Court preliminarily approved the settlement. Plaintiffs filed a Motion for Final Approval of the Settlement (“Motion for Final Approval”), which the Company did not oppose. Following a hearing on the Motion for Final Approval that was conducted on August 1, 2025, the Court ordered class counsel, the settlement administrator and the Company to implement the agreed upon settlement of the consolidated case. Pursuant to the settlement, the Company made settlement payments, the total of which did not have a material impact on the Company’s results of operations, financial position or liquidity, during the year ended December 31, 2025. Upon entry of the Final Order, the clerk was ordered to close the case. The Company received $21.5 million and $21.4 million of business insurance recovery proceeds related to the Cybersecurity Incident during the years ended December 31, 2025 and 2024, all of which was included in other non-operating gains on the Company's consolidated income statements. Acquisitions The Company has acquired, and plans to continue to acquire, businesses with prior operating histories. Acquired companies may have unknown or contingent liabilities, including liabilities for failure to comply with healthcare laws and regulations, such as billing and reimbursement, fraud and abuse and anti-kickback laws. The Company has from time to time identified certain past practices of acquired companies that do not conform to its standards. Although the Company institutes policies designed to conform such practices to its standards following completion of acquisitions, there can be no assurance that the Company will not become liable for the past activities of these acquired facilities that may later be asserted to be improper by private plaintiffs or government agencies. Although the Company generally seeks to obtain indemnification from prospective sellers covering such matters, there can be no assurance that any such matter will be covered by indemnification or, if covered, that such indemnification will be adequate to cover potential losses and fines. Employment Agreements Certain members of the Company's management have entered into employment agreements with the Company. The agreements provide for minimum salary levels, participation in bonus plans and amounts payable in connection with severance of employment from the Company. Letters of Credit Outstanding letters of credit are required principally by certain insurers and states to collateralize the Company’s workers’ compensation programs and self-insured retentions associated with its professional and general liability insurance programs. As of December 31, 2025 and 2024, the Company maintained outstanding letters of credit of approximately $30.4 million and $37.0 million, respectively.
