Performance Stock Units financial

"vesting of Performance Stock Units (PSUs) related to the February 28, 2025 performance award"

Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.

weighted average price financial

"The price in column 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.

Employee Share Purchase Plan financial

"acquired on May 29, 2026 by the reporting person pursuant to the Issuer's 2021 Employee Share Purchase Plan"

A program that lets employees buy their employer’s stock, often through regular payroll deductions and sometimes at a discounted price or with matching contributions; think of it as a company-run savings plan that converts part of pay into ownership. It matters to investors because it can increase insider ownership and employee motivation, potentially affecting company performance, and can slightly change share supply when new stock is issued or sold.
