Rule 10b5-1 Plan Adoption Date May 27, 2026 Date the trading plan governing these transactions was adopted
Non-qualified Stock Option financial
"Non-qualified Stock Option (Right to Buy)"
A non-qualified stock option (NSO) is a contract that lets an employee or service provider buy company shares at a fixed price for a set period, like a voucher to purchase stock later at today’s price. It matters to investors because exercising NSOs creates ordinary income for the holder and can increase share count, affecting a company’s earnings and ownership mix; think of it as a future sale that can dilute existing shareholders and has immediate tax consequences for the recipient.
Rule 10b5-1 trading plan regulatory
"made pursuant to a Rule 10b5-1 trading plan adopted on May 27, 2026"
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.
