Restricted Stock Unit financial
"Mr. Gould was granted a total of 54,995 unvested restricted stock unites ("RSUs")"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
Class A Ordinary Shares financial
"each representing a contingent right to receive one Class A ordinary share"
Class A ordinary shares are a type of ownership stake in a company that typically grants voting rights to shareholders, allowing them to have a say in important company decisions. They often come with priority in receiving dividends or profits, making them attractive to investors seeking influence and potential income. These shares help distinguish different levels of ownership and rights within a company's stock structure.
Grant Date financial
"On June 12, 2026 (the "Grant Date"), Mr. Gould was granted"
The grant date is the day a company formally gives an employee or contractor the right to receive stock-based compensation, such as stock options or restricted shares. It matters to investors because it fixes key terms—like the price, the start of the ownership clock, and when the award will affect the company’s financial statements and share count—so it can influence dilution, reported expenses, and potential future selling pressure.
vested financial
"On September 12, 2026, 3,437 of Mr. Gould's RSU's vested."
disposition to the Company financial
"The reported disposition to the Company reflects the settlement in cash"
