restricted share units financial

"These restricted share units were granted under the Issuer's Long Term Incentive Plan"

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.

Long Term Incentive Plan financial

"granted under the Issuer's Long Term Incentive Plan (the "Plan")"

A long term incentive plan is a company program that awards executives and key employees bonuses—often in stock, options, or cash—only if the business meets multi-year performance goals. It links management pay to company results—like tying a coach’s bonus to a team’s multi-season record—so investors monitor it for how leaders are motivated, potential share dilution, and signals about the company’s long-term priorities.
