Ceribell, Inc. (CBLL) reporting person Jane (Xingjuan) Chao filed an amended Form 4/A to correct omitted option exercises that occurred on April 17, 2025 and April 21, 2025. The amendment shows the exercise of 5,700 options on 04/17/2025 and 3,372 options on 04/21/2025 at a conversion/exercise price of $2.24 per share. The filings report resulting beneficial ownership totals of 757,851 and 761,223 common shares following those transactions. The Form states the option exercises were effected under a Rule 10b5-1 trading plan and that the options are fully vested and exercisable. The amendment was filed to correct understated ownership amounts in the original Form 4, which accurately reported the number of shares sold but omitted the immediate pre-sale exercises.

Insights

TL;DR: Routine amendment; option exercises recorded and linked to a Rule 10b5-1 plan, correcting prior reporting inaccuracies.

The amendment clarifies that the reporting person exercised a total of 9,072 options across two dates at $2.24 per share and that those options were fully vested and exercisable. The transactions were effected pursuant to a Rule 10b5-1 trading plan, which indicates pre-established trading instructions rather than opportunistic insider timing. The filing fixes prior disclosure omissions rather than revealing new strategic changes to ownership or control. For investors, this is primarily an administrative correction ensuring the public record accurately reflects the exercises and resulting beneficial ownership.

TL;DR: Governance process executed via a 10b5-1 plan; amendment improves transparency but highlights initial reporting oversight.

The amended Form 4/A demonstrates use of a formal trading plan and confirms the options were fully vested and exercisable at time of exercise. While the underlying economic impact appears routine, the need for an amendment indicates an earlier disclosure lapse that required correction. Timely and accurate Section 16 reporting is important for governance and market transparency; this amendment restores consistency between option exercise events and reported beneficial ownership levels.

Explanation of Responses:
1. This Form 4/A is being filed to correct the Form 4 filed on April 21, 2025 ("Original Filing"), which inadvertently omitted reporting option exercises that occurred on April 17, 2025 and April 21, 2025, immediately prior to the respective sales reported in the Original Filing. The number of shares sold as reported in the Original Filing was correct; however, the total number of shares beneficially owned was understated due to the omission of the option exercises. As a result, the totals reported in subsequent filing were also understated.
2. The transactions reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person.
3. The stock option is fully vested and currently exercisable.
