(1) Amounts as of December 31, 2023 and before that date differ from those in prior year consolidated financial statements as they were retrospectively adjusted as a result of the accounting or the Business Combination (as defined in the Notes to Consolidated Financial Statements).

(2) Amounts for the years ended December 31, 2024 and 2023 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.
