restricted stock units financial

"Reflects a grant of restricted stock units ("RSUs") which vest over 2 years"

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.

sell-to-cover transaction financial

"based on the actual sale price of shares sold on April 7, 2026 pursuant to a sell-to-cover transaction"

A sell-to-cover transaction is when a person granted company stock (for example as part of compensation or option exercise) immediately sells enough of those shares to pay required taxes or exercise costs and keeps the rest. Think of it like cashing part of a bonus to cover the tax bill; it provides necessary cash without the holder needing outside funds. Investors watch these sales because they increase trading volume and slightly reduce insider holdings, but they often reflect routine tax or cost management rather than a judgment on the company’s prospects.

par value per share financial

"one share of common stock, $0.01 par value per share (the "Common Stock")"
