Key Terms

4 terms

Restricted Units financial

"Restricted Units, which are 1-for-1 registered share equivalents, were acquired on May 22, 2026"

long-term incentive plan financial

"were acquired on May 22, 2026, pursuant to the Issuer's long-term incentive plan"

A long-term incentive plan is a company program that pays executives or employees with stock, options, or cash tied to multi-year performance goals, where the rewards become theirs only after meeting conditions over time. Think of it as a delayed bonus or retirement-style reward that aligns employees’ interests with shareholders by encouraging them to boost long-term value; investors watch these plans because they affect pay costs, share dilution and management incentives.

Annual General Meeting financial

"vest on the earlier of: (i) May 22, 2027, or (ii) the date of the next Annual General Meeting"

registered shares financial

"payable in registered shares of the Issuer following the applicable vesting date"

Shares that are recorded by name in a company’s official shareholder register, so the company knows exactly who owns them and must update its records when they change hands. For investors this matters because registered shares make it easier to receive dividends, vote at meetings and prove ownership—like having a named entry in an address book rather than an anonymous ticket—reducing confusion and improving legal and tax transparency.
