Rule 10b5-1 trading plan financial

"The sales reported by the Reporting Person were effected pursuant to a Rule 10b5-1 trading plan adopted December 29, 2025."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted-average price financial

"The "Amount" and "Price" reported in this Column 4 reflect the aggregate number and weighted-average price, respectively, of shares sold."

restricted stock units (RSUs) financial

"Certain of these securities are restricted stock units (RSUs). Each RSU represents a contingent right to receive one share of Class A Common Stock."

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

indirect ownership financial

"Consists of shares held by the Phillips Family Trust."

contingent right financial

"Each RSU represents a contingent right to receive one share of Class A Common Stock, subject to the applicable vesting schedule and conditions."
