[1] On March 1, 2021, all shares of the Company’s then-outstanding Class B common stock were automatically converted into the same number of shares of Class A common stock, pursuant to the terms of the Company’s amended and restated certificate of incorporation. No additional shares of Class B common stock will be issued following such conversion. See Note 11, “Equity,” for further details.

[2] In connection with a business combination completed on December 20, 2023, the Company issued approximately 0.2 million shares of its Class A common stock to one of its wholly-owned subsidiaries, in exchange for a noncontrolling equity interest in the acquired company that was held by the subsidiary prior to this business combination. These shares are treated as treasury stock for accounting purposes. See Note 7, “Business Combinations,” for further details.
