11. Commitments and Contingencies

We are involved in environmental remediation and monitoring activities at our Randolph, Wisconsin manufacturing facility. As a result, we accrue for related costs, when such costs are determined to be probable and estimable. We currently utilize a pump and treat remediation strategy, which includes semi-annual monitoring and reporting, consulting, and maintenance of monitoring wells. We recorded $0.1 million within other current liabilities and $0.8 million within other non-current liabilities as of May 31, 2026 and May 31, 2025 in the condensed consolidated balance sheets. These amounts are measured on an undiscounted basis over an estimated period of 15 years. In fiscal 2022, in collaboration with the Wisconsin Department of Natural Resources ("WDNR"), we initiated an in-situ chemical remediation pilot study, which ran over a two-year period. The results of this study were submitted to the WDNR as part of our standard annual report. If the WDNR were to require a change from the current pump and treat remediation strategy, this change could result in an increase in future costs and, ultimately, an increase in the currently recorded liability, with an offsetting charge to operations in the period recorded.

Related to the Company's other contingent liabilities, losses of $0.9 million and $1.4 million were recorded in the third quarter of fiscal year 2026 and 2025, respectively. These losses were driven by an updated valuation of the performance milestone liability for the Company's CAPInnoVet, Inc. transaction. Additionally, in the third quarter of fiscal year 2025, the Company reversed $0.9 million that was related to a contingent liability that was recorded as part of the Corvium, Inc. transaction. The final milestone payment was not achieved, resulting in a full reversal of the liability. Finally, in the third quarter of fiscal year 2025, the Company recorded a gain related to a settlement regarding the Company's prior acquisition of certain fixed assets. The amount of $2.7 million was received in the third quarter of fiscal year 2025. This amount was partially offset by a related fixed asset impairment of $2.1 million, which was due to the asset no longer being in use. The amount was recorded within General and administrative on the consolidated statements of operations within the Company's Food Safety operating segment.

In the third quarter of fiscal year 2024, the Company received $1.3 million of business interruption insurance proceeds relating to fire damage that occurred in the fourth quarter of fiscal year 2023 at one of our genomics lab facilities. The proceeds were recorded within Cost of Revenues in the consolidated statements of operations.

The Company has agreements with unrelated third parties that provide for the payment of royalties on the sale of certain products. Royalty expense, recorded in sales and marketing, under the terms of these agreements was $1.9 million, $1.6 million, and $3.3 million for fiscal years 2026, 2025 and 2024, respectively. Some of these agreements provide for guaranteed minimum royalty payments to be paid each fiscal year by the Company for certain technologies. Future minimum royalty payments are as follows: 2027—$0.3 million, 2028—$0.5 million, 2029—$0.1 million, and 2030—$0.1 million, and 2031—$0.1 million.

Shareholder Litigation and Stockholder Demands

On July 18, 2025, Operating Engineers Construction Industry and Miscellaneous Pension Fund filed a putative class action complaint in the United States District Court for the Western District of Michigan against the Company, John Adent, and David Naemura. The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 based on allegedly false and misleading public statements and omissions by defendants during the period January 5, 2023 through June 3, 2025 relating to the integration of the 3M business into Neogen. The complaint seeks, among other things, unspecified monetary damages, reasonable costs and expenses and/or other relief as deemed appropriate by the Court. On January 20, 2026, Plaintiffs filed an amended complaint. On February 10, 2026, Defendants filed a motion to dismiss the amended complaint in its entirety. The motion to dismiss is fully briefed and remains pending.

On August 27, 2025, the Company, John Adent, Steven J. Quinlan, James C. Borel, William T. Boehm, Ronald D. Green, Ralph A. Rodriguez, James P. Tobin, Darci L. Vetter, and Catherine E. Woteki were named in a putative class action filed in Minnesota’s Second Judicial District for Ramsey County. The complaint asserts claims under Sections 11, 12(a)(2), and 15 of the Securities Act of 1933 based on allegedly false and misleading public statements by defendants in the offering materials issued in connection with the 2022 transaction in which Neogen acquired 3M’s Food Safety Business. The complaint seeks, among other things, unspecified monetary damages, reasonable costs and expenses, recission, and/or such other equitable or injunctive relief as deemed appropriate by the Court. On February 3, 2026, Plaintiffs filed an amended complaint. On April 6, 2026, Defendants filed a motion to dismiss the amended complaint in its entirety. On June 5, 2026, Plaintiffs filed their opposition to the motion to dismiss.

On August 13, 2025, August 15, 2025, December 22, 2025, and January 27, 2026, the Company received four separate stockholder litigation demands requesting that the Board investigate the allegations in the federal securities class action and pursue claims on the Company’s behalf based on those allegations. On October 4, 2025, the Board established a litigation committee to consider and investigate the demands.

On December 4, 2025, the Company, John Adent, Dave Naemura, James C. Borel, Thierry Bernard, William T. Boehm, Jeffrey D. Capello, Ronald D. Green, Aashima Gupta, Raphael A. Rodriguez, James P. Tobin, Darci L. Vetter, and Catherine Woteki were named in a putative shareholder derivative action filed in the United States District Court for the Western District of Michigan. The complaint asserts claims for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment, waste of corporate assets, and violations of Section 14 of the Securities Exchange Act of 1934 based on allegedly false and misleading public statements by defendants related to the integration of the 3M business into Neogen. The complaint seeks, among other things, unspecified monetary damages, reasonable costs and expenses, rescission, and/or such other equitable or injunctive relief as deemed appropriate by the Court. On March 30, 2026, the parties stipulated to a stay of the derivative action pending the disposition of the motion to dismiss in the federal securities class action, which stipulation was so Ordered by the Court on April 1, 2026.

Given the uncertainty of litigation and the preliminary stage of the cases, we cannot estimate the reasonably possible loss or range of loss that may result from the actions.

Product Recall

On January 28, 2026, the Company initiated a voluntary recall of all unexpired lots of the Company’s Vet HyCoat® Hyaluronate Sodium Sterile Solution (the “Recalled Product”), due to microbial contamination in certain lots of 10 mL/50 mg product vials. The Recalled Product was distributed by the Company but manufactured by an unaffiliated third-party supplier. The Company received a number of reports of adverse events in horses following intraarticular injections of the Recalled Product, which is inconsistent with its labeled, intended use. To date, the Company has not received reports of adverse events when the Recalled Product is used in a manner consistent with the labeled intended use. While the Company’s investigation into this issue is ongoing, out of an abundance of caution, the 2 mL/20 mg product vials were recalled. The recall

affects approximately 133,000 unexpired units sold since 2023; though returns are expected to be less due to product use since that time. These units were sold into the U.S. market, Puerto Rico and certain Latin American markets between February 2023 and November 2025. The Company has worked cooperatively with the U.S. Food and Drug Administration (FDA) throughout this process and is offering a full refund to affected customers. In February 2026, we recorded a $0.6 million accrual in other current liabilities, which represents our estimate of the aggregate amount of refunds to be paid to affected customers.

As of the date of this filing, the Company has received several demand letters from parties asserting claims relating to their use of the Recalled Product (the “Product Claims”). The Company is also aware of two individual lawsuits, one filed on March 25, 2026, and the other filed on June 9, 2026, and an uncertified class action lawsuit filed on April 13, 2026, on behalf of one named plaintiff. The Company believes it has strong defenses to any claims brought relating to this matter, including the fact that the Company served only as a distributor and was not involved in any way in the manufacture of the Recalled Product. In addition, although the Company’s investigation is ongoing, initial evidence reflects adverse events only when the Recalled Product was used in a manner inconsistent with its labeled, intended use.

Based on information currently available, the Company believes it is probable that it will incur a loss related to the Product Claims. However, given the preliminary nature of the claims received and the uncertainty regarding the number and validity of potential claims, and the range of potential outcomes, the amount or materiality of loss cannot be reasonably estimated. Accordingly, no accrual for loss contingencies related to these Product Claims has been recorded as of the end of the period covered by this report.

The Company will continue to evaluate information as it becomes available and will record an accrual for estimated losses relating to these Product Claims at the time when the amount of loss can reasonably be estimated. At this juncture, the Company does not believe the ultimate resolution of these Product Claims is likely to have a material adverse effect on the Company’s financial position, results of operations, or cash flows.

In addition to the items disclosed above, we are subject to certain other legal and other proceedings in the ordinary course of our business that, in the opinion of management, are not expected to have a material effect on our financial statements.
