3 terms

Rule 10b5-1 plan regulatory

"This transaction was executed pursuant to a Rule 10b5-1 plan adopted by the Reporting Person on December 12, 2025."

A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.

A Ordinary Shares financial

"security_title: "A Ordinary Shares" for the reported transactions."

weighted average price financial

"This price reflects the weighted average price for open-market sales of Shares on June 15, 2026 within a $1.00 range."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
