(1) Amounts and per share amounts for the year ended December 31, 2024 differ from those published in prior consolidated financial statements as they were retrospectively adjusted as a result of the Reverse Stock Split (as described below in Note 1, The Company and Summary of Significant Accounting Policies). Specifically, the number of common shares outstanding during periods before the Reverse Stock Split are divided by the exchange ratio of 3:1, such that each three shares of common stock were combined and reconstituted into one share of common stock effective October 23, 2025.

During the year ended December 31, 2024, a total of 766,333options were granted to employees and nonemployees with a weighted-average grant date fair value of $ 1.38per share. There were nooptions granted during year ended December 31, 2023.
