Key Terms

4 terms

Class A Common Shares financial

"Represents holdings of Class A Common Shares following the reported entry."

A Class A common share is a specific type of ordinary company share that represents an ownership stake and usually carries particular voting rights or payout priorities compared with other share classes. For investors it matters because those differences affect how much influence you have over company decisions, how dividends or liquidation proceeds might be distributed, and how easily the shares trade — like choosing between car models where one has extra features (more control) and another focuses on price or availability (liquidity).

Restricted Stock Units financial

"Represents an award of Restricted Stock Units granted to the Reporting Person on March 18, 2026."

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.

Grant Date financial

"Granted to the Reporting Person on March 18, 2026 (the "Grant Date")."

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.

Reporting Person financial

"Represents an award of Restricted Stock Units granted to the Reporting Person on March 18, 2026."
