Inotiv Inc., a contract research and laboratory services company, faced investor claims tied to its 2021 acquisition of Envigo RMS, a large provider of research-model animals and related services used by pharmaceutical and biotech firms. The settlement covers people who bought Inotiv stock between Sept. 21, 2021, and May 20, 2022, as well as certain shareholders who held shares as of the Oct. 4, 2021 voting record date for the deal. At the core is a familiar scenario in merger-driven public markets: investors allege that upbeat statements about an acquisition (and the target’s operations) didn’t fully reflect key risks, and that the truth only emerged later through “corrective” disclosures that coincided with a stock drop. The lawsuit was filed under federal securities laws—typically relying on Section 10(b) of the Securities Exchange Act and SEC Rule 10b‑5 (plus related provisions)—which prohibit materially false or misleading statements or omissions in connection with buying or selling securities. Plaintiffs alleged Inotiv and certain executives misrepresented or failed to disclose important information about Envigo RMS and related business practices, inflating Inotiv’s share price and harming investors when the market repriced the stock. Inotiv denies wrongdoing but agreed to an $8.75 million settlement to avoid the cost and uncertainty of litigation; payments will be allocated pro rata based on documented trading history and a court-approved “recognized loss” formula that also reflects the PSLRA’s 90-day lookback concept used to limit certain damages calculations. More broadly, this case fits into a steady stream of merger- and operations-related securities class actions where the alleged problem isn’t the deal itself, but what investors say they weren’t told about regulatory, compliance, or operational constraints that could affect performance post-acquisition. The life-sciences supply chain is heavily regulated, and companies supporting biomedical research operate under a web of oversight and standards—from SEC disclosure obligations for public companies to animal welfare and research compliance regimes such as the Animal Welfare Act and USDA enforcement, as well as AAALAC accreditation expectations and institutional animal care and use committee (IACUC) protocols—making transparency about compliance risks and disruptions particularly consequential when a transaction’s value depends on stable, licensable operations and predictable customer demand.
