Restricted Stock Units financial
"Each RSU represents a contingent right to receive one share of the Company common stock."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Performance Stock Units financial
"Each performance stock unit ("PSU") represents a contingent right to receive one share"
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.
2026 long-term incentive program financial
"pursuant to the 2026 long-term incentive program approved by the Board of Directors"
EBITDA financial
"The PSUs are subject to the achievement of performance conditions based on EBITDA, weighted at 100%"
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It measures a company's profitability by focusing on the money it makes from its core operations, ignoring expenses like taxes and accounting adjustments. Investors use EBITDA to compare how well different companies are performing financially, as it provides a clearer picture of operational success without the influence of financial structure or accounting choices.
2023 Omnibus Incentive Plan financial
"granted 22,859 RSUs under the Company's 2023 Omnibus Incentive Plan, as may be amended"
