Restricted Stock Units ("RSUs") financial
"This transaction represents the vesting on June 23, 2026 of 125,000 Restricted Stock Units ("RSUs") granted on June 23, 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 57,925 shares of Common Stock withheld for tax obligations in connection with the settlement"
2021 Equity Incentive Plan financial
"granted on June 23, 2025 under the Company's 2021 Equity Incentive Plan (as amended and restated on April 22, 2024)"
beneficially owned financial
"The 1,864,660 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.
