sell-to-cover financial
"policy requiring sell-to-cover to satisfy tax obligations of the Reporting Person"
Sell-to-cover is when part of newly issued or exercised company stock is immediately sold to pay required taxes and fees, so the recipient keeps the remaining shares. For investors this matters because it reduces the number of shares insiders or employees actually hold after a grant, can create small, routine share sales that aren’t signal of cashing out, and slightly increases share supply on the market—like selling a portion of a paycheck to cover the tax bill.
restricted stock units financial
"tax obligations ... incurred with the vesting and settlement of restricted stock units"
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.
weighted average sale price financial
"The reported price in Column 4 is a weighted average sale price."
Employee Stock Purchase Plan financial
"acquired on May 20, 2026 under the Issuer's 2024 Employee Stock Purchase Plan."
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
indirect ownership financial
"Shares are held directly by the Baily Goldstein Living Trust ... and by family members"
