RADNOR, Pa., March 9, 2026 /PRNewswire/ —

IN THE DISTRICT COURT OF OKLAHOMA COUNTY
STATE OF OKLAHOMA

SUMMARY NOTICE OF CLASS ACTION

TO:     Any former record holders and all beneficial owners of the common stock of Continental Resources, Inc. (“Continental”) who held or owned such stock at any time during the period beginning on and including October 17, 2022, through and including November 22, 2022 (the “Class Period”), including any and all of their respective legal representatives, trustees, executors, administrators, estates, heirs, and any Person acting for or on behalf of, or claiming under, any of them (excluding Defendants and their immediate family members, affiliates, subsidiaries, legal representatives, heirs, estates, successors or assigns; and any entity in which any Defendant has or had a direct or indirect controlling interest) (the “Class”).

YOU ARE HEREBY NOTIFIED, pursuant to 12 O.S. § 2023 and an Order of the District Court of Oklahoma County, State of Oklahoma (the “Court”), that the above-captioned action (“Action”) has been certified as a class action on behalf of the Class set forth above. The defendants in the Action are (i) Harold Hamm (“Hamm”), Shelly Lambertz, and the Hamm Family Affiliates¹ (collectively, the “Controlling Defendants”); and (ii) William B. Berry, John T. McNabb, II, and Mark E. Monroe (the “Director Defendants,” and together with the Controlling Defendants, “Defendants”). Plaintiffs allege that Defendants breached their fiduciary duties in connection with the November 2022 transaction whereby Continental’s former minority shareholders were bought out by Hamm and his affiliates for $74.28 per share (the “Transaction”).  Plaintiffs allege that Hamm and the other Controller Defendants caused the Class to be cashed out of their Continental shares for inadequate consideration after an unfair process.  Plaintiffs further allege that Hamm breached his fiduciary duties by engaging in insider trading prior to publicly announcing his offer to take Continental private. Plaintiffs Ralph Donald Turlington and Pembroke Pines Firefighters & Police Officers Pension Fund have been appointed by the Court to serve as Class Representatives on behalf of the Class. The parties have conducted substantial discovery.  On December 16, 2025, the Court granted the motion for summary judgment filed by former defendants Ellis L. McCain and Timothy G. Taylor, who negotiated the Transaction on behalf of Continental’s then minority shareholders, and dismissed all claims asserted against them in this Action. The Court also granted summary judgment in favor of several defendants relating to plaintiffs’ insider trading allegations. The Court further denied Plaintiffs’ motion for leave to file an amended class action petition adding Continental’s in-house legal counsel as a defendant. A trial is currently set to begin on May 4, 2026.
