Nano Nuclear Energy Inc.

Item 1. Legal Proceedings.

From time to time, we may become involved in various lawsuits and legal proceedings which arise in the ordinary course of business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows, except for the following:

On August 9, 2024, a putative securities class action lawsuit was filed against us and certain of our officers in the United States District Court for the Southern District of New York, captionedYvette Yang v. Nano Nuclear Energy Inc., et al., No. 1:24-cv-06057 (S.D.N.Y.). As previously reported, on January 8, 2026, the court issued an order granting defendants’ motion to dismiss, and on February 12, 2026, the court entered judgment in favor of defendants. Plaintiff has filed an appeal in the United States Court of Appeals for the Second Circuit, which the parties are in the process of briefing. We disputed the allegations in the amended complaint and will continue to defend the case vigorously.

In addition, on August 23, 2024, a putative shareholder derivative lawsuit was filed purportedly on behalf of our company, as nominal defendant, against certain of our directors and officers in the Eighth Judicial District Court of Clark County, Nevada, captioned William Latza, Derivatively on Behalf of Nano Nuclear, Inc. v. James Walker, et al., No. A-24-900423-C. As previously reported, on October 30, 2025, the court entered a formal order and statement of decision granting separate motions to dismiss filed by us and our directors and officers. On February 10, 2026, plaintiff and defendants filed a stipulation to dismiss the case with prejudice, with each side bearing its own costs and fees, and the court entered an order dismissing the case with prejudice.

In addition, from time to time, we may be subject to various additional claims, lawsuits, and other legal and administrative proceedings that may arise in the ordinary course of business. Some of these claims, lawsuits, and other proceedings may range in complexity and result in substantial uncertainty; it is possible that they may result in damages, fines, penalties, non-monetary sanctions, or relief.

As we continue to grow and develop our products, we anticipate that we will expend significant financial and managerial resources in the defense of our products in the future. We also anticipate that we will expend significant financial and managerial resources to defend against claims that our products and services infringe upon the intellectual property rights of third parties.
