Mehta. The amended complaint alleges that (i) Armistice facilitated the sale of assets of Cerecor, Inc., in 2019 and Innovus Pharmaceuticals, Inc., in 2020 to Aytu in exchange for convertible securities, which it subsequently converted and sold at a profit on the open market; (ii) the Armistice defendants breached their fiduciary duties, were unjustly enriched and wasted corporate assets in connection with these acquisitions; (iii) the Armistice defendants breached their fiduciary duties by engaging in insider trading; and (iv) the other directors breached their fiduciary duties, and aided and abetted the Armistice defendants’ breaches of fiduciary duties, in connection with these acquisitions. The amended complaint seeks unspecified damages, equitable relief, restitution, disgorgement of profits, enhanced governance and internal procedures, and attorneys’ fees. While the Company believes that this lawsuit is without merit and has vigorously defended against it, the Company has agreed to settle the matter, as against it and the director defendants other than Mr. Boyd, for various corporate governance modifications and the payment of plaintiff’s attorneys’ fees. That settlement is subject to court approval, the hearing on which has not yet been scheduled. Sabby Litigation A complaint was filed on February 22, 2023, in the Supreme Court of the State of New York by Sabby Volatility Warrant Master Fund Ltd (“Sabby”) and Walleye Opportunities Master Fund Ltd (“Walleye”), holders of certain warrants to purchase common stock, against the Company. The complaint alleges that the Company improperly adjusted the exercise price of the warrants and miscalculated the number of shares the warrant holders may receive, and that the Company failed to provide prompt notice to the warrant holders of such adjustment. The complaint seeks a declaratory judgment of the warrant share calculation, that 575,000 warrant shares be due to Sabby on exercise of its warrants rather than 312,908 shares, and that 100,000 warrant shares be due to Walleye on exercise of its warrants rather than 54,146 shares. In October 2023, the Company entered into a settlement agreement and general release with Sabby and Walleye. Stein Litigation Cielo Stein (“Stein”), a former sales specialist, filed a complaint on February 1, 2023, in Jefferson County Circuit Court in Kentucky against the Company and its wholly owned subsidiary Neos Therapeutics. The complaint alleges that Aytu retaliated against Stein in violation of the Kentucky Civil Rights Act after she opposed what she contends was unwelcome behavior by her supervisor. The complaint also alleges that the Company’s response to Stein’s subsequent complaint to human resources was inadequate. The complaint seeks an award of unspecified compensatory damages, emotional-distress damages, and attorneys’ fees and costs. The Company removed the lawsuit to the United States District Court for the Western District of Kentucky and filed a motion to dismiss the complaint, which was denied. A Section 16 pretrial conference is scheduled for June 3, 2024. Due to the early stage of litigation, and while the Company believes that this lawsuit is without merit, the Company is not able to predict at this time whether this proceeding will have a material impact on its financial condition or results of operations and intend to vigorously defend this case.
