In an order entered on May 21, 2026, the Delaware Court of Chancery stayed a shareholder derivative action brought by KSF on behalf of Acadia Healthcare in light of the parties’ agreement in principle to settle the claims asserted therein and in certain related derivative actions.

KSF filed an ERISA class action complaint on April 17, 2026, against Providence Health & Services, St. Joseph Health System, and certain of their officers and directors alleging that defendants breached their fiduciary duties.

Vice Chancellor Nathan A. Cook denied the defendants’ motion to dismiss KSF's class action complaint in its entirety. KSF's complaint, filed in the Delaware Court of Chancery on behalf of former stockholders of Trecora Resources Inc., alleges that Trecora’s directors breached their duty of loyalty in connection with the sale of Trecora.

Plaintiffs allege that defendants breached their fiduciary duties by, among other things, failing to divest underperforming investments, engaging in transactions prohibited by ERISA.
