restricted stock units ("RSUs") financial

"The reported securities represent restricted stock units ("RSUs") which each entitle the reporting person to receive one share"

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.

vesting financial

"RSUs will vest in three installments of 30% on April 26, 2026, 30% on April 26, 2027 and 40% on April 26, 2028"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

continued employment financial

"subject to continued employment through each such date"

Continued employment means that an individual remains in their current job without interruption. For investors, it signals stability and ongoing work that can affect company performance and future prospects. Like a steady heartbeat for a business, sustained employment helps ensure consistent operations and financial health.
