Ceribell (CBLL) CFO Scott Blumberg Exercises 36,000 Options

What Happened

• Scott Blumberg, Chief Financial Officer of Ceribell, exercised a total of 36,000 option-derived shares on December 22, 2025 (4,752 + 11,529 + 19,719). The reported exercise price for each conversion is $0.00 and the filing shows $0 total cash paid; this Form 4/A amends a prior Form 4 to correct aggregated amounts that had omitted the incentive stock option portion of the grants. The transactions were reported as derivative exercises (code M).

Key Details

• Transaction date: 2025-12-22 (three derivative exercise entries totaling 36,000 shares)
• Reported exercise price/value: $0.00 (filing shows $0)
• Shares owned after transaction: not disclosed in the provided excerpt
• Notable footnotes:
  • F1: Transactions were effected pursuant to a Rule 10b5-1 trading plan adopted March 14, 2025.
  • F2: The stock option is fully vested and currently exercisable.
  • F3: The option vests 1/48 monthly beginning April 1, 2023 (subject to continued service).
• Filing amendment: Form 4/A filed 2026-08-20 corrects an error in the original Form 4 filed Dec 29, 2025 (original omitted the incentive stock option portion).

Context

• These were option exercises (conversion of derivative securities to shares). The filing does not indicate whether underlying shares were subsequently sold or retained; exercise price reported as $0.00 is the amount shown on the Form 4, not the market value of the shares at exercise. Exercises are common insider events and do not by themselves signal a buy/sell view of the company's stock. The presence of a 10b5-1 plan indicates the trades were executed under a pre-established plan.
