Stock Option (Right to Buy) financial
"security_title": "Stock Option (Right to Buy)""
open-market sale financial
"transaction_action": "open-market sale""
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
derivative exercise/conversion financial
"transaction_action": "derivative exercise/conversion""
vesting financial
"47,619 shares subject to the option vested on October 1, 2025"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
monthly installments financial
"1/36 of the remaining shares subject to the option vest in equal monthly installments"
Monthly installments are regular, fixed payments made each month to gradually pay off a larger amount, such as a loan or purchase. Think of it like paying for a big item in small, manageable parts instead of all at once. For investors, understanding installment payments helps gauge how debts are structured and how they might affect financial stability or cash flow over time.
