Equity Compensation financial

"8490 | 02/24/2023 | Equity Compensation Common | 03/23/2023"

Equity compensation is pay given to employees, executives or contractors in the form of company ownership—such as stock, stock options or restricted shares—rather than just cash. It matters to investors because it can align workers' incentives with shareholders (like paying someone in slices of the same pie they help grow), but it also increases the number of shares outstanding and company expenses, affecting ownership percentages and earnings per share.

PSU financial

"02/24/2023 | PSU / RSU Lapse | IMPINJ, INC."

A PSU is a company where the government owns a controlling stake and often plays a direct role in its management and strategy. Think of it like a business that operates with public oversight, similar to a town-run utility versus a private neighborhood service. Investors watch PSUs differently because government involvement can affect profits, dividend policies, regulatory treatment and stability, so these stocks may behave more like policy instruments than pure market-driven enterprises.

RSU financial

"02/24/2023 | PSU / RSU Lapse | IMPINJ, INC."

Restricted stock units (RSUs) are a form of company shares given to employees as part of their compensation, usually with certain restrictions or conditions, such as remaining with the company for a set period. When these restrictions lift, employees receive actual shares that they can sell or hold. For investors, RSUs can impact a company's stock supply and reflect the company's commitment to attracting and retaining talent.

Restricted Stock financial

"03/23/2023 | Restricted Stock Lapse | IMPINJ, INC."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.
