What insider transaction did CERO (CERO) report in this Form 4?

CERO reported a stock option grant to director Francois Eric. He received options over 1,823,278 Common Stock shares as equity compensation, rather than buying shares in the open market, reflecting a non-cash award tied to future vesting conditions.

How many CERO shares are covered by Francois Eric’s new stock options?

The grant covers options on 1,823,278 shares of CERO Common Stock. This entire amount was awarded in a single transaction and represents Eric’s reported post-transaction option holdings linked to this grant in the filing.

What is the exercise price of Francois Eric’s CERO stock option grant?

The options have an exercise price of $0.055 per share. This price is the amount Eric would pay per share to convert the stock options into CERO Common Stock if he exercises the award after vesting.

When do Francois Eric’s CERO stock options vest?

The options vest in full on the earlier of August 13, 2026 or upon achievement of a specified clinical milestone in 2026. Vesting is conditional on Eric’s continuous service through whichever vesting event occurs first.

What is the expiration date of the CERO stock options granted to Francois Eric?

The options expire on March 3, 2036. After this date, any unexercised portion of the 1,823,278-share grant will lapse, meaning Eric would no longer be able to purchase CERO shares under this award.

Is Francois Eric’s CERO Form 4 transaction an open-market purchase or sale?

It is not an open-market trade. The Form 4 reports a stock option grant coded as a grant or award acquisition, meaning CERO awarded options to Eric as compensation rather than him buying or selling shares on the market.
