4 terms

restricted stock units ("RSUs") financial

"Company granted restricted stock units ("RSUs") issued pursuant to a Rule 16b-3 plan."

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.

Rule 16b-3 plan regulatory

"Company granted restricted stock units ("RSUs") issued pursuant to a Rule 16b-3 plan."

grant date financial

"payable in shares of common stock on the first anniversary of the grant date or when the reporting person ceases to be a director"

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.
