A federal investor class action filed in 2016 reached trial before Judge Ed Kinkeade in the Northern District of Texas after nearly a decade of litigation [1][2]. Plaintiffs, a certified class of investors identified as Ramirez et al., alleged that ExxonMobil and certain former officers made materially misleading disclosures concerning the company's bitumen proved reserves in its Canadian oil sands operations and its Rocky Mountain dry gas assets [1][2]. The claims proceeded under Section 10(b) of the Securities Exchange Act and SEC Rule 10b-5 [1]. The case carried significance beyond the parties: it was the first securities class action centered on climate-change accounting and asset valuation ever tried to a jury verdict [1][2].
After a three-week trial, the jury returned a unanimous defense verdict on May 14, 2026, finding that ExxonMobil's disclosures were not materially misleading and that the company did not violate federal securities law [1][2][3]. The verdict cleared both ExxonMobil Corp. and the former officers named as individual defendants [1]. ExxonMobil was represented at trial by Scott Thomas, Sarah Tomkowiak, and Heather Waller of Latham & Watkins [1].
Because the jury found for the defense on all claims, no damages were awarded and no compensatory or punitive amounts are at issue [2][3]. The verdict extinguishes the class's monetary claims arising from the challenged reserve and asset disclosures.
The decision carries forward-looking weight for climate-related disclosure litigation. Courts and litigants evaluating whether climate accounting representations give rise to Section 10(b) liability now have the first trial-level jury resolution on that question [1][2]. Whether plaintiffs pursue post-trial motions or an appeal to the Fifth Circuit has not been publicly confirmed as of the verdict date, but the complete and unanimous nature of the defense verdict narrows the procedural avenues available to the class [2][3].
