What Happened Manni Joseph S., Chief Revenue Officer of Ceribell, sold 1,378 shares on May 21, 2026 at $18.00 per share for total proceeds of $24,804.

Key Details

• Sale: 1,378 shares disposed on 2026-05-21 at $18.00 per share — $24,804 total. (Transaction code S)
• Award/vest: 3,500 post‑split shares recorded on 2026-03-10 as a performance-based option vesting. (Transaction code A; $0 reported)
• Footnote F1: Shares sold were used to satisfy tax withholding obligations tied to RSU vesting.
• Footnote F2: The option traces to an April 23, 2024 grant (originally 140,000 pre-split / 54,472 post-split), subject to annual performance vesting; the 2024 portion was canceled and 3,500 post‑split shares vested for the 2025 fiscal year.
• Footnote F3: The stock option became fully vested and exercisable on March 15, 2026.
• Shares owned after the transactions: not specified in the provided filing.
• Filing timeliness: Form 4 was filed on 2026-05-26 for transactions dated 2026-03-10 and 2026-05-21 (~2.5 months after the March vesting); this appears to be a late filing (a compliance item, not a commentary on the trade itself).

Context The sale was a routine tax-withholding disposition tied to equity vesting (common for executives) and not a straightforward market-sale signal of confidence. The March entry reflects vesting of a performance-based option (derivative award) that was later fully vested and is exercisable as of March 15, 2026.
