(the “the Company”) against current and former officers and directors of the Company in the previously disclosed stockholder derivative action entitled Pearl v. Dutt, et al. (Case No. 3:25-cv-00373-JO-DDL) pending before the Court in accordance with the Stipulation and Agreement of Settlement, dated August 12, 2025 (the “Stipulation”). The Stipulation calls for the Company to implement and maintain certain corporate governance reforms and enhancements and for the payment of attorneys’ fees and reimbursement of expenses for plaintiff’s counsel and a service award for plaintiff, in the aggregate amount of $425,000.
