Restricted stock units financial

"Restricted stock units granted pursuant to the company's 2025 Equity Incentive Plan"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

2025 Equity Incentive Plan financial

"granted pursuant to the company's 2025 Equity Incentive Plan in accordance"

long-term compensation program financial

"in accordance with the company's long-term compensation program"

InterDigital Savings and Protection Plan financial

"pursuant to the InterDigital Savings and Protection Plan"

beneficially owned financial

"the reporting person beneficially owned this number of whole shares of common stock"

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.
