Deferred Stock Units (DSUs) financial

"These shares were granted as Deferred Stock Units (DSUs) and vest upon grant"

Deferred stock units (DSUs) are a form of long-term pay that promises an employee or director future company shares or cash equal to the share value at a later date, usually after leaving the company or at a set vesting time. Think of them as a delayed paycheck tied to the stock: they align recipients’ interests with long-term share performance and matter to investors because they create potential future dilution and signal how management is rewarded and incentivized.

clawback financial

"with the right of the Company to clawback the value of the DSUs within one year"

A clawback is a contractual or legal right to recover money that was already paid out—often executive bonuses, incentives, or erroneous payments—when certain conditions change, such as fraud, accounting mistakes, or failure to meet performance targets. It matters to investors because clawbacks protect shareholder value by discouraging risky or misleading behavior, can affect future cash flow and executive incentives, and signal stronger governance, much like a store recalling a refund after discovering it was issued in error.
