Rule 10b5-1 trading plan regulatory

"Exercised and sold pursuant to a 10b5-1 trading plan adopted by the Reporting Person on December 4, 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.

Stock Option (Right to Buy) financial

"security_title: Stock Option (Right to Buy)"

Exercise or conversion of derivative security financial

"transaction_code_description: Exercise or conversion of derivative security"

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.
