Nano Nuclear Energy Inc.

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, captioned Yvette Yang v. Nano Nuclear Energy Inc., et al., No. 1:24-cv-06057 (S.D.N.Y.). On October 28, 2024, the court entered an order appointing Hongyu Xie as lead plaintiff. On January 6, 2025, lead plaintiff filed an amended complaint, naming as defendants the Company, Jay Yu, James Walker, and Jaisun Garcha. The amended complaint asserts claims for alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of persons who purchased or otherwise acquired our securities from May 8, 2024 through July 30, 2024. The claims in the amended complaint relate to statements made by us and/or our directors or officers concerning the Company’s business and prospects, including our progress toward development of nuclear microreactors and fuel manufacturing facilities. On February 21, 2025, all defendants filed a motion to dismiss the amended complaint pursuant to Rules 12(b)(6) and 9(b) of the Federal Rules of Civil Procedure, for failure to state a claim upon which relief can be granted. On February 24, 2025, the court sua sponte entered an order permitting lead plaintiff to file a second amended complaint or stand on her amended complaint. On March 14, 2025, lead plaintiff filed a second amended complaint, asserting the same claims asserted in the amended complaint. On April 11, 2025, all defendants filed a motion to dismiss the second amended complaint pursuant to Rules 12(b)(6) and 9(b) of the Federal Rules of Civil Procedure, for failure to state a claim upon which relief can be granted. A hearing on the motion has not been scheduled. We dispute the allegations in the amended complaint and intend to defend the case vigorously. The case is at an early stage and we cannot reasonably estimate the amount of any potential financial loss or cost that could result from the lawsuit.

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. On December 20, 2024, plaintiff filed an amended complaint, alleging claims for alleged breach of fiduciary duties, corporate waste, market manipulation, and racketeering, among others. The claims asserted in the amended complaint relate to our management, business and prospects, including, among others, our progress toward microreactor development, the qualifications of our management, and our investment in LIS Technologies Inc. On behalf of our company, the plaintiff seeks damages from the director and officer defendants and an order directing our company to take actions to reform and improve corporate governance and internal procedures. On February 4, 2025, our company filed a motion to dismiss the amended complaint pursuant to Rule 23.1 of the Nevada Rules of Civil Procedure for failure to make a demand or alleged demand futility, and our directors and officers filed a motion to dismiss the amended complaint pursuant to Rules 12(b)(5) and 23.1 of the Nevada Rules of Civil Procedure for failure to state a claim on which relief can be granted and plaintiff’s lack of standing. On April 24, 2025, the court heard and granted both the Company’s motion to dismiss and the directors’ and officers’ motion to dismiss without leave to amend. On October 30, 2025, the court entered a formal written order and statement of decision granting the motions to dismiss. On November 21, 2025, plaintiff filed a notice of appeal with the Nevada Supreme Court. No briefing dates for the appeal have been scheduled. The director and officer defendants deny all allegations of liability and intend to continue vigorously defending against all claims.

On behalf of our company, the plaintiff seeks damages from the director and officer defendants and an order directing our company to take actions to reform and improve corporate governance and internal procedures. The director and officer defendants deny all allegations of liability and intend to vigorously defend against all claims. Given the preliminary stage of the lawsuit and the inherent uncertainties of litigation, we cannot determine with certainty the outcome of the case at this time.

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.
