¹ The weighted average number of common shares outstanding as of March 31, 2024 included the weighted average effect of the 450,409 pre-funded warrants issued in connection with a registered direct offering the Company entered into on February 15, 2024 (see Note 10 – Capital Stock and Warrants) because the exercise of such warrants required nominal consideration ($0.001 per share exercise price for each pre-funded warrant). As of March 31, 2024, none of the pre-funded warrants had been exercised; therefore, all 450,409 outstanding pre-funded warrants as of that date are not included in the table above. As of March 31, 2025, these pre-funded warrants have been exercised.
