"…granted pursuant to the Issuer's 2018 Equity Incentive Plan (as amended)."

annual shareholder meeting financial

"…vest on the earlier of: (i) the first anniversary... or (ii) the day prior to the Issuer's next annual shareholder meeting."

A yearly gathering where a company’s owners (shareholders) and its leaders meet to review performance, approve key decisions like electing directors, and vote on issues such as executive pay or major policy changes. Think of it as an annual town hall for people who own part of the business: investors use it to ask questions, influence direction through votes, and gauge management’s plans and transparency, all of which can affect the stock’s outlook.

change in control financial

"…(ii) a change in control (as defined in the DRSU agreement) or (iii) ten years from the Transaction Date."

A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.
