  1. Each restricted stock unit represents a contingent right to receive one share of the Issuer's Class A Common Stock, subject to the reporting person's continued service to the Issuer on the applicable vesting date. The entire award vested or vests on the earlier of the: (i) one year anniversary of the grant date or (ii) date of the Issuer's 2026 annual stockholders' meeting. These restricted stock units do not expire; they either vest or are cancelled prior to the vesting date. All of the restricted stock units vest on the earlier of the: (i) one year anniversary of the grant date or (ii) date of the Issuer's 2027 annual stockholders' meeting. On the vesting date, pursuant to the reporting person's election, the restricted stock units will automatically convert into an equal number of deferred stock units, which will be settled for an equal number of shares of the Issuer's Class A Common Stock on the tenth anniversary of the grant date. Notwithstanding the aforementioned deferral period, from and after the vesting date, the deferred stock units may automatically settle earlier upon the reporting person's death, disability, or separation from service with the Issuer, or upon the occurrence of an "unforeseeable emergency," as that term is defined under the deferred compensation program. The deferred restricted stock units do not expire; they either will vest on the vesting date and settle for shares at the end of the deferral period or they will be cancelled prior to the vesting date in the event the reporting person ceases to provide services to the Issuer.

Deferred Restricted Stock Units financial
"The deferred restricted stock units do not expire; they either will vest on the vesting date and settle for shares at the end of the deferral period..."
Deferred restricted stock units are promises by a company to give employees or executives company shares at a future date, subject to conditions like continued employment or performance targets; the delivery and tax event are intentionally delayed. They matter to investors because they affect when new shares may be issued and how executives are motivated—like a paycheck held in escrow that vests over time, influencing potential share dilution and management behavior.
Restricted Stock Units financial
"Each restricted stock unit represents a contingent right to receive one share of the Issuer's Class A Common Stock..."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
