Restricted Stock Units ("RSUs") financial
"This transaction represents the vesting on April 29, 2026 of 161,290 Restricted Stock Units ("RSUs") granted on April 29, 2025"
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.
withheld for tax obligations financial
"This transaction represents 74,742 shares of Common Stock withheld for tax obligations in connection with the settlement"
beneficially owned financial
"The 1,570,885 shares of Common Stock beneficially owned following the reported transactions reflects"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
Equity Incentive Plan financial
"RSUs granted on April 29, 2025 under the Company's 2021 Equity Incentive Plan (as amended and restated on April 22, 2024)"
An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.
annual installments financial
"vested in three equal annual installments: one-third vested on April 29, 2026; one-third will vest on April 29, 2027"
