The Original Prospectus Supplement was subsequently amended by amendment no. 1 dated July 30, 2025 (the “First Amendment”). As of September 30, 2026, we had offered and sold 189,522,984 shares of our Class A common stock in the ATM Offering for gross proceeds of $1,174,785,034.

We are filing amendment no. 2 to the Original Prospectus Supplement, as amended by the First Amendment, with the Securities and Exchange Commission, to be dated October 28, 2026 (the “Second Amendment”), to increase the aggregate dollar amount of shares of Class A common stock available for sale in the ATM Offering to $1,000,000,000, which includes $245,835,654 remaining under the Original Prospectus Supplement, as amended by the First Amendment.
