Miami International Holdings, Inc.

Item 8.01 Other Events. On July 20, 2026, the U.S. District Court for the District of New Jersey (the “Court”) entered an Order of Dismissal With Prejudice (the “Order”) that dismisses all claims for relief and counterclaims asserted in the previously disclosed litigation between Miami International Holdings, Inc. and certain of its subsidiaries (the “Company”) and Nasdaq, Inc. and certain of its subsidiaries (“Nasdaq”, such matter, the “Litigation”). The parties have now resolved all claims and counterclaims against each other that have been or could have been asserted in the Litigation. The Company remains free to operate its business without any license or consent being required from Nasdaq with respect to all matters asserted by Nasdaq in the Litigation, and the Company may freely operate or modify existing exchanges and trading platforms, create and operate new exchanges and trading platforms, and license, commercialize, improve, utilize, implement, and sell any technology, without ever being subject to a claim that such activity infringes any rights of Nasdaq that were asserted in the Litigation. This matter was first brought on September 1, 2017 when Nasdaq filed an action against the Company in the Court. In December of 2018, the Litigation was temporarily stayed pending the resolution of proceedings before the Patent Trial and Appeal Board (“PTAB”) at the United States Patent and Trademark Office. In 2019, the PTAB invalidated six patents that were asserted by Nasdaq against the Company in the Litigation. On August 31, 2021, the Company filed in the Court its Answer and Counterclaims against Nasdaq and the stay in the Court was lifted in June 2022. For further details on the history of the Litigation see the Company's Annual Report on Form 10-K for the year ended December 31, 2025 and other filings with the Securities and Exchange Commission.
