[1] (1) Amounts as of March 31, 2021 and before that date differ from those published in prior consolidated financial statements as they were retrospectively adjusted as a result of the accounting for the Business Combinations (as defined below in Note 1). Specifically, the number of common shares outstanding during periods before the Business Combinations are computed on the basis of the number of common shares of UpHealth Holdings (accounting acquiror) during those periods multiplied by the exchange ratio established in the stock purchase agreement (1.00 UpHealth Holdings shares converted to 10.28 GigCapital2 shares). Common stock and additional paid-in capital were adjusted accordingly.
