ASP Isotopes Inc.

Item 1. Legal Proceedings.

Except as described herein, we are currently not party to, and our property is not currently the subject of, any material pending legal matters or claims.

On December 4, 2024, a purported stockholder of the Company filed a putative securities class action on behalf of purchasers of the Company’s securities between October 30, 2024 through November 26, 2024 against ASP Isotopes Inc. and certain of its executive officers in the United States District Court for the Southern District of New York (Corredor v. ASP Isotopes Inc., et al., Case No. 1:24-cv-09253 (S.D.N.Y)) (the “Securities Class Action”). The Securities Class Action alleges that the Company, its chief executive officer and chief financial officer (“Defendants”) made materially misleading or false statements or omissions regarding the Company’s business and asserts purported claims under §§ 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 promulgated thereunder. The complaint seeks unspecified compensatory damages, attorney’s fees and costs. On May 2, 2025 the Court appointed Mark Leone (“Leone”) as lead plaintiff and directed the Clerk of court to amend the caption to substitute Leone for Alexander Corredor as plaintiff. On May 2, 2025 the Court also appointed lead counsel and set deadlines for filing an amended consolidated class action complaint and briefing schedules for a motion to dismiss, if any, and class certification. On May 27, 2025, Leone and two additional named plaintiffs (“Plaintiffs”) filed the amended class action complaint (“Amended Complaint”), that asserts the same causes of action and seeks the same relief as the initial complaint and is based upon substantially similar factual allegations as the initial complaint. On June 27, 2025, Defendants filed a motion to dismiss the Amended Complaint. Also on June 27, 2025, Plaintiffs filed a motion for class certification. On July 25, 2025, Plaintiffs filed an opposition to Defendants’ motion to dismiss. Also on July 25, 2025, Defendants filed an opposition to Plaintiffs’ motion for class certification. Defendants intend to vigorously defend against the Securities Class Action; however, we cannot be certain of the outcome and, if decided adversely to us, our business and financial condition may be adversely affected.

In addition to the matters described above, from time to time, we may become subject to arbitration, litigation or claims arising in the ordinary course of business. The results of any current or future claims or proceedings cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and litigation costs, diversion of management resources, reputational harm and other factors.
