  1. In connection with the vesting on May 27, 2026, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,126 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,126 shares of phantom stock pursuant to the Issuer's deferred compensation plan. The Reporting Person is therefore reporting the disposition of 1,126 shares of Class A Common Stock in exchange for an equal number of shares of phantom stock. A portion of these securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock. These securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock. 1/4th of the RSUs shall vest on each of August 20, 2026, November 20, 2026 and February 20, 2027, and the remaining 1/4th of the RSUs shall vest on the earlier of (i) the day before the annual meeting of stockholders held in 2027 or (ii) May 28, 2027, subject to the Reporting Person continuing as a service provider through each vest date.

Restricted Stock Units ("RSUs") financial
"These securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share..."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
phantom stock financial
"The Reporting Person's receipt of 1,126 shares of Class A Common Stock was deferred, resulting in ... phantom stock..."
A phantom stock is a form of compensation that gives employees or executives the benefits of stock ownership, such as the increase in stock value, without actually giving them real shares. It acts like a promise to pay the employee the equivalent value of company stock later, often as a bonus or incentive. This allows companies to motivate and reward staff without diluting ownership or transferring actual shares.
deferred compensation plan financial
"phantom stock pursuant to the Issuer's deferred compensation plan."
A deferred compensation plan is an arrangement where an employer agrees to pay part of an employee’s pay or bonus at a later date instead of immediately, often to reduce current tax bills or to tie rewards to long-term performance. For investors it matters because these promises create future cash obligations and influence executive incentives and retention; they can affect a company’s reported liabilities, cash flow planning and the risk profile if the business faces financial trouble.
separation from service financial
"The phantom stock becomes payable in one lump sum payment upon separation from service."
