ORDER ON DEFENDANTS' MOTION TO DISMISS This matter is before the Court on a Motion to Dismiss filed pursuant to Federal Rules of Civil Procedure 23.1 and 12(b)(6) by Defendants, who are former or current officers and directors of nominal defendant Cummins, Inc. ("Cummins")1 (Filing No. 87). In December 2023, Cummins announced that it would pay over two billion dollars to settle claims that it had violated federal and state diesel emissions laws. Thereafter, Cummins stock price fell precipitously, and this shareholder derivative action followed. Four shareholders—Joshua Ingersoll, the Oklahoma Firefighters Pension and Retirement System, the City of Southgate Police and Fire Retirement System, and the Vladimir Gusinsky Revocable Trust (collectively, "Plaintiffs")—assert federal claims under Section 14(a) of the Securities Exchange Act of 1934 (the "Securities Act") and state law claims for breach of fiduciary duty. For the reasons discussed below, the Court grants the Motion to Dismiss without prejudice as to Plaintiffs' federal claims, and grants leave to file an amended complaint. And as explained in this Order, if the federal claims are not successfully repleaded, the Court intends to relinquish jurisdiction over the state law claims. I. BACKGROUND The following facts are not necessarily objectively true, but as required when reviewing a motion to dismiss, the Court accepts as true all factual allegations in the complaint and draws all inferences in favor of Plaintiffs as the non-moving party. See Bielanski v. Cnty. of Kane, 550 F.3d

1 "Cummins" refers to nominal defendant Cummins, Inc. "Defendants" refers to the fourteen individual defendants. 632, 633 (7th Cir. 2008). These facts are not intended to provide a comprehensive explanation of all the facts in this case; rather, it provides the background relevant to the issues before the Court. Cummins is an Indiana-based multinational company that manufactures diesel engines that are used in many top-selling trucks in the United States, including RAM and Nissan pickup trucks (Okla. Firefighters Pension & Ret. Sys. v. Belske, No. 1:25-cv-01792, Dkt. 1 ¶¶ 2, 38–42).2 All

engines sold in the United States are subject to emissions standards under the Clean Air Act and contain emissions control systems intended to limit a vehicle's emissions during regular use. Id. ¶ 2, 43. Companies sometimes attempt to evade these emissions requirements by equipping vehicles with "defeat devices" which are devices designed to activate the emissions control systems only during vehicle testing and "defeat" the control systems during regular use, allowing vehicles to produce impermissible levels of emissions. Id. ¶ 45. The Clean Air Act prohibits the use of defeat devices. Id. (quoting 42 U.S.C. §§ 85, 7522(a)(3)(B)). To ensure compliance with the Clean Air Act and other similar regulations, the Environmental Protection Agency ("EPA") requires manufacturers, including Cummins, to obtain certificates that disclose all emissions

control devices installed in vehicles, provide information about the parameters and justifications for those devices, and explain why they are not defeat devices. Id. ¶¶ 46–48. The EPA has enforced the prohibition on defeat devices against several major manufacturers, resulting in fines, recalls, and modifications affecting millions of vehicles. Cummins is no exception. In 1998, Cummins and six other manufacturers entered into a settlement and consent decree (the "Consent Decree") with the EPA and Department of Justice ("DOJ"), which entailed millions of dollars in fines, a commitment to spend over one billion dollars to resolve the claims, and a promise not to violate the Clean Air Act in the future. Id. ¶¶ 53–54.

2 The operative Complaint was filed in a separate action, Okla. Firefighters Pension & Ret. Sys. v. Belske, No. 1:25- cv-01792-TWP-MKK (S.D. Ind. Sept. 9, 2025), and has not been re-docketed in this action. Cummins disclosed the Consent Decree to shareholders in March 1999 in an annual report. That report stated that Cummins had "developed extensive corporate action plans to comply with all aspects of the Consent Decree." Id. ¶ 55. According to the Consolidated Complaint, this was untrue. Cummins had not developed any such action plans and did not have any internal controls

to oversee compliance with the Consent Decree. Id. ¶ 57. Cummins admitted to violating the Consent Decree in September 2006, October 2006, and February 2010, resulting in more fines and remedial measures. Id. ¶¶ 4, 58–63. Between 2010 and 2019, Cummins promoted its compliance with clean air regulations, despite allegedly continuing to install defeat devices and failing to establish reporting or control systems to monitor compliance with those regulations. But the Board meeting minutes for those years make no mention of any discussion regarding regulatory compliance or any reports from Cummins' Audit Committee or Safety, Environment, and Technology Committee on compliance. Id. ¶¶ 64–69. In September 2015, the EPA announced that Volkswagen had been using defeat devices. Id. ¶ 70. That same month, the California Air Resources Board ("CARB") issued a letter to all

engine manufacturers warning that defeat devices were prohibited by California law and that the CARB would begin implementing new, additional emissions tests. Id. ¶ 71. In October 2015, Cummins management provided a report to the Board on "the Volkswagen situation." Id. ¶ 72. Despite this report, the Board did not investigate whether Cummins was installing defeat devices or implementing any systems to ensure Cummins' compliance with environmental laws. Id. In November 2015, Volkswagen was again found to have violated clean air laws; in January 2017, Volkswagen pled guilty to criminal charges; and in April 2017, a federal court ordered Volkswagen to pay a $2.8 billion criminal fine. Id. ¶¶ 73–78. Around that same time, Cummins was named in a consumer class action lawsuit regarding excess nitrogen oxide emissions from diesel engines in certain model year 2007–2012 RAM trucks. Id. ¶ 75. But despite all of this news, Cummins' Board failed to assess Cummins' potential exposure to liability. Id. ¶¶ 73–74. The Board meeting minutes for 2016 and 2017, like the minutes for prior years, do not reflect any discussion of Cummins' compliance with clean air laws or any presentation by the Audit Committee or Safety,

Environment, and Technology Committee on regulatory compliance. Id. ¶¶ 75–78.
