CONTINGENCIES	12. CONTINGENCIES AND COMMITMENTS Litigation Envigo RMS, LLC (“Envigo RMS”) is a defendant in a purported class action and a related action under California’s Private Attorney General Act of 2004 (“PAGA”) brought by Jacob Greenwell, a former non-exempt employee of Envigo RMS, on June 25, 2021 in the Superior Court of California, Alameda County. The complaints allege that Envigo RMS violated certain wage and hour requirements under the California Labor Code. PAGA authorizes private attorneys to bring claims on behalf of the State of California and aggrieved employees for violations of California’s wage and hour laws. The class action complaint seeks certification of a class of similarly situated employees and the award of actual, consequential and incidental losses and damages for the alleged violations. The PAGA complaint seeks civil penalties pursuant to the California Labor Code and attorney’s fees. On June 2, 2023, Envigo RMS and the plaintiff signed a Memorandum of Understanding (“MOU”) that sets forth the parties’ intent to settle these matters for $795 which includes attorneys’ fees. On August 2, 2024, the parties entered into a Joint Stipulation of Class Action and PAGA Settlement and Release of Claims (the “Agreement”) that incorporated the material terms of the MOU and is subject to court approval. The Agreement contains no admission of liability or wrongdoing by Envigo RMS. The Agreement provides that, if the settlement is approved by the court, the settlement amount would be paid in four quarterly installments, with the first one to be funded after the court’s final approval of the settlement, and the following ones in the three subsequent quarters. A motion for preliminary approval of the settlement has been filed and is set for hearing on June 12, 2025. While the timeline for final court approval is not yet determined, the Company took a reserve equal to the proposed settlement amount, which is included in accrued expenses and other current liabilities. On June 23, 2022, a putative securities class action lawsuit was filed in the United States District Court for the Northern District of Indiana, naming the Company and Robert W. Leasure and Beth A. Taylor as defendants, captioned Grobler v. Inotiv, Inc., et al., Case No. 4:22-cv-00045 (N.D. Ind.). The complaint alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, and Rule 10b-5 promulgated thereunder, based on alleged false and misleading statements and material omissions regarding the Company’s acquisition of Envigo RMS and its regulatory compliance. On September 12, 2022, Oklahoma Police Pension and Retirement System was appointed by the Court as lead plaintiff. Thereafter, on November 14, 2022, the lead plaintiff filed an amended complaint against the same defendants, in addition to John E. Sagartz and Carmen Wilbourn, that asserted the same claims along with a claim under Section 14(a) of the Exchange Act. On November 23, 2022, the lead plaintiff filed a further amended complaint against the aforementioned defendants asserting the same claims as the amended complaint and further alleging that false and misleading statements and material omissions were made concerning the Company’s non-human primate business. The purported class in the operative complaint includes all persons who purchased or otherwise acquired the Company’s common stock between September 21, 2021 and November 16, 2022, and the complaint seeks an unspecified amount of monetary damages, interest, fees and expenses of attorneys and experts, and other relief. On January 27, 2023, the defendants filed a motion to dismiss the amended complaint. That motion was fully briefed by April 28, 2023. On March 29, 2024, the Court issued a decision denying, in part, Defendants’ motion to dismiss. The case is now in discovery. While the Company cannot predict the outcome of this matter, the Company believes the class action to be without merit and plans to vigorously defend itself. We cannot reasonably estimate the maximum potential exposure or the range of possible loss for this matter. On September 9, 2022, a purported shareholder derivative lawsuit was filed in the United States District Court for the Northern District of Indiana, naming Robert W. Leasure, Beth A. Taylor, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Grobler v. Robert W. Leasure, et al., Case No. 4:22-cv-00064 (N.D. Ind.) (the “Grobler Derivative Action”). On January 4, 2023, an additional shareholder derivative lawsuit was filed in the United States District Court for the Northern District of Indiana, naming Robert W. Leasure, Beth A. Taylor, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Burkhart v. Robert W. Leasure, et al., Case No 4:23-cv-00003 (N.D. Ind.) (the “Burkhart Derivative Action,” and together with the Grobler Derivative Action, the “Federal Derivative Actions”). The Federal Derivative Actions collectively assert claims for breach of fiduciary duty, abuse of control, gross mismanagement, and waste of corporate assets, as well as violations of Sections 10(b), 14(a), and 21D of the Exchange Act arising out of the Company’s acquisition of Envigo and its regulatory compliance. The Court consolidated the Federal Derivative Actions on April 24, 2024, and Plaintiffs filed a consolidated complaint on June 24, 2024. The consolidated Federal Derivative Actions are currently stayed pursuant to the securities class action matter. While the Company cannot predict the outcome of these matters, the Company believes the consolidated Federal Derivative Actions to be without merit and plans to vigorously defend itself. We cannot reasonably estimate the maximum potential exposure or the range of possible loss for any of these matters. On April 20, 2023, a purported shareholder derivative lawsuit was filed in the State of Indiana Tippecanoe County Circuit Court, naming Robert W. Leasure, Beth A. Taylor, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Whitfield v. Gregory C. Davis, et al., Case No. 79C01-2304-PL-000048 (Tippecanoe Circuit Court) (the “Whitfield Derivative Action”). On June 2, 2023, an additional shareholder derivative lawsuit was filed in the Indiana Commercial Court of Marion County, naming Robert W. Leasure, Beth A. Taylor, Carmen Wilbourn, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Castro v. Robert W. Leasure, et al., Case No. 49D01-2306-PL-022213 (Marion Superior Court 1) (the “Castro Derivative Action,” and together with the Whitfield Derivative Action, the “State Derivative Actions”). The State Derivative Actions collectively assert claims for breach of fiduciary duty, unjust enrichment, aiding and abetting breach of fiduciary duty, and waste of corporate assets arising out of the Company’s acquisition of Envigo and its regulatory compliance, and the Company’s non-human primate business. On August 24, 2023, the Castro Derivative Action was transferred to the Tippecanoe County Circuit Court and consolidated with the Whitfield Derivative Action. The consolidated State Derivative Actions are currently stayed pursuant to the securities class action matter. While the Company cannot predict the outcome of these matters, the Company believes the consolidated State Derivative Actions to be without merit and plans to vigorously defend itself. We cannot reasonably estimate the maximum potential exposure or the range of possible loss for any of these matters. On January 13, 2022, the Company filed a complaint against Freese and Nichols, Inc. ("FNI") titled Envigo RMS Holding Corp. and Envigo Global Services, Inc. v. Freese and Nichols, Inc., Case No. 22-01-61647-CV, in the District Court of Jim Wells County, Texas, 79th Judicial District related to, among other things, FNI’s failure to design an adequately sized lagoon to dispose of the current wastewater and wastewater from expanded operations in the future. The complaint asserted claims against FNI for negligence, negligence per se, and breach of contract seeking damages and attorney fees and costs. On February 14, 2025, the Company (through two of its subsidiaries) entered into a Settlement Agreement (the “Settlement Agreement”) with FNI to settle the lawsuit. The Settlement Agreement provides that the parties fully resolve all claims set forth in such lawsuit, without any admission of liability, and that FNI will pay the Company $7,550 within 30 days following the date of the Settlement Agreement. The Court granted the Company's Agreed Motion to Dismiss All Claims on March 27, 2025. The Company received the settlement payment in full prior to March 31, 2025. The $7,550 settlement payment is presented within other operating income (expense) within the condensed consolidated statement of operations. The Company is party to certain other legal actions arising out of the normal course of its business. In management's opinion, none of these actions will have a material effect on the Company's operations, financial condition or liquidity. Government Investigations and Actions The Company is subject to and/or involved in government investigations, inquiries and actions, including those described below. Given their inherent uncertainty, except as otherwise noted, the Company cannot predict the duration or outcome of the pending matter described below. An adverse outcome of the matter could have a material adverse impact on the Company’s operations, financial condition, operating results and cash flows. On May 23, 2023, Inotiv received a voluntary request from the U.S. Securities and Exchange Commission (“SEC”) seeking documents and information for the period December 1, 2017 to the present regarding the Company, Envigo Global Services, Inc. ("EGSI"), and OBRC’s importation of NHPs from Asia, including information relating to whether their importation practices complied with the U.S. Foreign Corrupt Practices Act. In March 2024, the SEC provided the Company a formal order of investigation concerning this matter that is dated January 9, 2024, and on April 12, 2024, the SEC provided supplemental document requests to the Company. The Company is cooperating with the SEC. Resolution Agreement and Plea Agreement On June 3, 2024, the Company announced that it had reached agreement with the DOJ to resolve a previously-announced criminal investigation into its shuttered canine breeding facility located in Cumberland, Virginia, which was operated originally by Envigo RMS in November 2021. In connection with such resolution, the Company and its related entities entered into the Resolution Agreement (the "Resolution Agreement") with the DOJ and the U.S. Attorney’s Office for the Western District of Virginia ("USAO-WDV"), and Envigo RMS and EGSI entered into the Plea Agreement (the “Plea Agreement”) with the DOJ and the USAO-WDV. On June 3, 2024, before the United States District Court for the Western District of Virginia, Envigo RMS pleaded guilty to one misdemeanor count of conspiracy to violate the Animal Welfare Act and EGSI pleaded guilty to one felony count of conspiracy to violate the Clean Water Act. On October 24, 2024, the Court sentenced Envigo RMS and EGSI according to the terms agreed to between the DOJ and the Company in the Resolution Agreement and Plea Agreement. Pursuant to the Resolution Agreement and the Plea Agreement, the Company, Envigo RMS and EGSI, among other matters, have agreed to: (i) make payments totaling $22,000 in fines, with $5,000 payable on each of June 3, 2025, 2026 and 2027, and $7,000 (plus accrued interest beginning on the sentencing date) payable on June 3, 2028; (ii) on June 3, 2024, pay $3,000, split between the Virginia Animal Fighting Taskforce and the Humane Society of the United States in recognition of assistance provided to the U.S. Government’s investigation; (iii) on June 3, 2024, pay $3,500 to the National Fish and Wildlife Foundation to fund environmental projects, studies, and initiatives in Cumberland County, Virginia; (iv) expend at least $7,000 ($2,500 by June 3, 2025, $2,500 by June 3, 2026, and $2,000 by June 3, 2027) for improvements to its facilities and personnel related to the welfare of animals; (v) provide a lien to the United States against sufficient Company assets to secure the deferred payments in connection with the $22,000 fine, which lien will be junior to only the lien provided by the Company to lenders under its credit facility as of April 1, 2024 and additional liens to secure up to $100,000 of additional debt; (vi) meet specified standards with respect to the health, safety and well-being of animals under the Company’s care; (vii) develop, adopt, implement, fund and comply with a comprehensive nationwide compliance plan related to applicable laws; and (viii) on January 20, 2025, appoint the Compliance Monitor to review the Company’s care of animals and compliance with certain laws, and to pay all associated costs, which Compliance Monitor shall serve for a term that expires on January 20, 2030, five years from appointment of the Compliance Monitor, unless the Company is released from probation prior to completion of the five-year term, in which case the monitorship term shall expire on January 20, 2028, three years from appointment of the Compliance Monitor, or two months after the completion of probation, whichever is later. In addition, the pleas result in Envigo RMS and EGSI being subject to probation for up to five years, with the potential to end the term early at a minimum of three years if the Company complies with the elements of the resolution.
