restricted stock units ("RSUs") financial
"Represents shares of Common Stock underlying restricted stock units ("RSUs") granted to the reporting person on May 20, 2026"
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.
2023 Incentive Plan financial
"RSUs granted to the reporting person on May 20, 2026 pursuant to the Issuer's 2023 Incentive Plan."
Annual Meeting of Stockholders financial
"will vest in full ... immediately prior to the Issuer's 2027 Annual Meeting of Stockholders, subject to continued service"
irrevocable trust financial
"2012 IRREVOCABLE TRUST DTD 08/10/2012, for which the reporting person serves as Trustee and exercises investing authority"
An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
