Restricted Share Units financial

"in connection with the settlement of Restricted Share Units, which vested on February 21, 2026"

Restricted share units (RSUs) are a promise from a company to give an employee or service provider actual shares or cash equal to the shares after certain conditions are met, typically staying with the company for a set time or hitting performance targets. Think of them like a time-locked gift card that becomes usable only after you’ve earned it. For investors, RSUs matter because they align employee incentives with company performance and can increase the number of shares outstanding over time, diluting existing ownership and affecting earnings per share.

weighted average price financial

"The sale price included on this Form 4 is a weighted average price."

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.

blackout period financial

"settled in Common Shares of the Issuer following the end of the Issuer's blackout period on April 1, 2026."

A blackout period is a temporary window when company insiders, employees or certain plan participants are barred from buying or selling the company’s stock, usually around earnings releases or other material events. It matters to investors because it reduces the risk of unfair trading based on secret information and can affect share liquidity and timing—think of it as a “no trading” zone set to keep the market fair and orderly.

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.
