change in control financial

"will become fully vested should a "change in control" of the Issuer occur"

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.

FAQ

What insider transaction did Nkarta (NKTX) report for Angela Thedinga?

Nkarta reported a grant of stock options to director Angela Thedinga for 37,000 shares of common stock. These options are a compensation-related award, not an open-market purchase or sale, and give her the right to buy shares at a fixed exercise price.

How many Nkarta (NKTX) shares are covered by Angela Thedinga’s new options?

The grant covers options on 37,000 shares of Nkarta common stock. This full amount was reported as held following the transaction, indicating it is a new award rather than a trade in previously held options or shares.

What is the exercise price of Angela Thedinga’s Nkarta (NKTX) stock options?

The options have an exercise price of $2.46 per share. This price is the cost at which she can acquire Nkarta common stock in the future, regardless of the market price at the time of exercise, as long as the options are vested and unexpired.

When do Angela Thedinga’s Nkarta (NKTX) stock options vest?

All shares subject to the option vest 100% on the first to occur of June 10, 2027 or the day immediately preceding the first annual meeting of stockholders after the grant date. This structure ties vesting to both time served and the company’s annual meeting cycle.

Do Angela Thedinga’s Nkarta (NKTX) options have any accelerated vesting terms?

Yes. Any unvested portion of the grant becomes fully vested if there is a “change in control” of Nkarta, or if Angela Thedinga’s service ends due to death or “disability,” as described in the applicable award agreement. These provisions protect the director in certain major events.

When do Angela Thedinga’s Nkarta (NKTX) stock options expire?

The options expire on June 9, 2036. After this expiration date, any portion not exercised will no longer be exercisable, even if it had vested previously, so exercise must occur before that deadline under the terms of the award.
