On June 10, 2026, a purported securities class action complaint was filed against us and certain of our officers in the United States District Court for the Southern District of California. The complaint alleges violations of the federal securities laws and seeks damages, costs, and other unspecified relief. No lead plaintiff has been appointed, and no class has been certified. We believe the claims are without merit and intend to defend the matter vigorously. In August 2026, a putative stockholder derivative complaint was filed in the United States District Court for the Southern District of California, captioned ES Trust v. Lim, et al., Case No. 3:26-cv-04517-WQH-JAC. The complaint named us as a nominal defendant and our current directors and Chief Financial Officer and Chief Business Officer as defendants. The complaint includes allegations of breaches of fiduciary duty and violations of Section 14(a) of the Exchange Act in connection with our oversight of, and public disclosures concerning ERAS-0015. The lawsuit seeks unspecified damages, costs, and other unspecified relief. The matter is at an early stage, and we are unable to predict the outcome of this proceeding or estimate a possible loss or range of loss, if any, at this time. We and the individual defendants dispute the allegations in the derivative action and intend to vigorously defend against the matter. From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Regardless of outcome, such proceedings or claims can have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained.
