Rule 10b5-1 trading plan financial
"The sales reported on this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted on June 2, 2025."
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
Employee Stock Purchase Plan financial
"These shares were acquired under the Issuer's Employee Stock Purchase Plan in a transaction that was exempt under both Rule 16b-3(d) and Rule 16b-3(c)."
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.
restricted stock units financial
"Represents shares that have been withheld by the Issuer to satisfy its income tax and withholding and remittance obligations in connection with the net settlement of restricted stock units and does not represent a sale by the Reporting Person."
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. These shares were sold in multiple transactions at prices ranging from $67.18 to $68.16 per share."
