Restricted stock units ("RSUs") financial

"Restricted stock units ("RSUs") convert into common stock on a one-for-one basis."

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.

Performance stock units ("PSUs") financial

"Performance stock units ("PSUs") convert into common stock on a one-for-one basis."

Rule 10b5-1 plan regulatory

"Transaction effected pursuant to a Rule 10b5-1 plan adopted by the Reporting Person on December 15, 2023."

A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.
