performance stock units financial

"The shares of Common Stock were acquired upon the vesting of certain performance stock units previously granted"

Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.

tax withholding obligation financial

"The shares of Common Stock were withheld to satisfy the reporting person's tax withholding obligation upon the vesting"

relative total shareholder return financial

"required relative total shareholder return over the 36-month period commencing on June 15, 2023, and ending on June 14, 2026"

Relative total shareholder return measures how much an investor’s gain from a company — including stock price changes and dividends — beats or lags a chosen benchmark or peer group over a set time. Think of it as a race: it shows whether the company outpaced rivals or the market, which helps investors and boards judge performance, compare returns fairly, and link results to pay or investment decisions.

Compensation Committee financial

"upon the determination of the Compensation Committee of the Board of the attainment of the required relative total shareholder return"

A compensation committee is a group within a company's leadership responsible for setting and reviewing how much top executives and employees are paid, including salaries, bonuses, and benefits. It matters to investors because fair and effective pay decisions can influence a company's performance, leadership motivation, and overall governance, helping ensure that the company’s management is aligned with shareholders’ interests.

beneficially owned financial

"The shares of Common Stock are beneficially owned by various trusts for the benefit of the reporting person and his spouse"

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.
