Company 2025 Omnibus Incentive Plan In order to incentivize our employees and other service providers following the completion of the IPO, our board of directors has adopted the 2025 Plan for eligible employees, consultants, and directors. Our named executive officers are eligible to participate in the 2025 Plan, which became effective in connection with the IPO. The 2025 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, other stock-based awards, cash awards, and substitute awards intended to align the interests of service providers, including our named executive officers, with those of our stockholders. Securities to be Offered Subject to adjustment in the event of certain transactions or changes of capitalization in accordance with the 2025 Plan, 8,415,306 shares of Class A Common Stock (the “Share Reserve”) were reserved for issuance pursuant to awards under the 2025 Plan. The total number of shares reserved for issuance under the 2025 Plan will be increased annually on January 1 of each fiscal year beginning in 2026 and ending and including 132

January 1, 2035, by the lesser of (i) 2% of the aggregate number of shares of Common Stock, outstanding on December 31 of the immediately preceding calendar year and (ii) the
number of shares of Class A Common Stock as is determined by our board of directors. No more than the initial Share Reserve may be issued pursuant to incentive stock options. Shares of Class A Common Stock subject to an award that expires
or is canceled, forfeited, exchanged, settled in cash or otherwise terminated without delivery of shares and shares withheld to pay the exercise price of, or to satisfy the withholding obligations with respect to, an award will again be available
for delivery pursuant to other awards under the 2025 Plan.
