On October 10, 2025, the Company submitted an appeal of the termination, and intends to pursue its dispute resolution remedies in connection with the termination of the grant. On October 13, 2025, one of the Company’s institutional investors exercised 1,886,793 common stock warrants at an exercise price of $2.80 per share. The warrant exercise resulted in gross proceeds of approximately $5.3 million to the Company. The shares were issued in accordance with the original warrant terms. On October 16, 2025, holders of warrants to purchase an aggregate of 2,923,360 shares of the Company’s common stock exercised their warrants on a cashless basis in accordance with the terms of the warrant agreements. In connection with the cashless exercises, the Company issued an aggregate of 2,634,984 shares of common stock and no cash proceeds were received. On October 16, 2025, the Company announced the publication of the S-K 1300 Technical Report and PFS disclosing mineral reserves and mineral resources, including economic assessment, for its Tonopah Flats Lithium Project (“TFLP”) near Tonopah, Nevada.

As a result, following the fiscal year ended, the Company’s net cash position has improved to $54.9 million as of November 3, 2025.
