Deferred Stock Unit financial

"Each deferred stock unit represents a contingent right to receive one share of Issuer common stock."

A deferred stock unit (DSU) is a promise from a company to give an employee or director the value of a share at a future date, paid in actual shares or cash when certain conditions are met (such as retirement or a set date). Think of it like a gift card that converts to company stock later; it aligns pay with long‑term performance and can affect future share count, compensation expense and potential cash needs, so investors watch DSUs for their impact on dilution and company finances.

Non-Qualified Stock Option financial

"Grant of option to buy shares of Issuer common stock..."

A non-qualified stock option (NSO) is a contract that lets an employee or service provider buy company shares at a fixed price for a set period, like a voucher to purchase stock later at today’s price. It matters to investors because exercising NSOs creates ordinary income for the holder and can increase share count, affecting a company’s earnings and ownership mix; think of it as a future sale that can dilute existing shareholders and has immediate tax consequences for the recipient.

annual meeting of shareholders financial

"vest in one installment on the one year anniversary...or on the date of the 2027 annual meeting of shareholders"

A yearly gathering where a company’s owners (shareholders) vote on key items like electing the board, approving executive pay, and ratifying auditors, and receive updates on performance and strategy. Think of it as an annual town hall for owners: it matters to investors because outcomes and disclosures can affect leadership, corporate direction, dividend and governance policies, and therefore the company’s risk and potential return.

Board of Directors financial

"following the date of the Director's resignation from the Board of Directors."

The Board of Directors is a group of people chosen by a company's owners to help make big decisions and oversee how the company is run. They act like a team of advisors or managers, making sure the company stays on track and meets its goals. Their choices can influence the company's success and how it grows.
