performance unit award financial

"On June 1, 2023, the reporting person was granted a performance unit award vesting on March 31, 2026"

restricted stock units financial

"On May 12, 2026, the reporting person was granted an award of restricted stock units"

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.

return on invested capital financial

"certifying the Issuer's return on invested capital performance during the applicable performance period"

A percentage that shows how effectively a company turns the money invested in its business—both borrowed funds and shareholders’ equity—into operating profit after taxes. It tells investors whether a company earns more from its core operations than it costs to fund those operations; think of it like the annual return you’d expect from renovating a rental property—higher percentages mean the company uses capital more efficiently and is more likely to create value for shareholders.

adjusted earnings before interest, taxes, depreciation and amortization financial

"certifying the Issuer's adjusted earnings before interest, taxes, depreciation and amortization during the applicable performance period"

Adjusted earnings before interest, taxes, depreciation and amortization is a company’s reported operating profit with routine financing costs, tax charges and accounting for wear-and-tear removed, plus extra adjustments to strip out one-time, unusual or non-cash items. Think of it as the company’s recurring cash-generating performance after removing accounting noise; investors use it to compare profitability, assess ability to pay debt and value a business more evenly across firms and time.

fair market value financial

"Sales price is the fair market value on Tuesday, May 12, 2026"

The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.
