"award was made in accordance with the terms of the Issuer's 2023 Stock Incentive Plan"

Change in Control financial

"shares underlying the Option will fully vest upon a Change in Control"

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.

vesting financial

"underlying the Option will vest in full upon the one-year anniversary of the date of grant"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
