[1] On December 22, 2025, the Company completed a 1-for-24 reverse stock split of its issued and outstanding Common Stock, no par value (the “December 2025 Reverse Split”). On May 4, 2026, the Company completed a 1-for-20 reverse stock split of its issued and outstanding common stock, no par value, (the “May 2026 Reverse Split”, and together with the December 2025 Reverse Split, the “Reverse Stock Splits”). As a result of the Reverse Stock Splits, the number of issued and outstanding shares of Common Stock of the Company as of June 30, 2026 was reduced from 50,410,884 to 2,520,581 shares, and the number of issued and outstanding shares of Common Stock as of September 30, 2025 was retroactively adjusted to 26,976 shares to give effect to the Reverse Stock Splits. The Reverse Stock Splits did not reduce the number of authorized shares of Common Stock and did not change the par value of the Common Stock. The Reverse Stock Splits affected all stockholders uniformly. Except to the extent that the Reverse Stock Split resulted in the stockholders’ fractional shares being rounded up on the participant level, no other effects affect stockholder’s ownership percentage of the Company’s shares of Common Stock. All references to number of shares, and to per share information in the consolidated financial statements have been retroactively adjusted to give effects to the Reverse Stock Splits.
