- F1: Acquisitions were from the issuer under a Subscription Agreement dated Mar 9, 2026.
- F2: Reporting person is a manager of NEA 17 GP, LLC (the GP structure described); the filing disclaims beneficial ownership of securities held by NEA 17 in which the reporting person has no pecuniary interest.
- F3: The pre-funded warrants are exercisable into common stock subject to a 9.99% ownership cap (holder may increase this cap to up to 19.99% with prior notice).
- Transaction code: P = Purchase. The second line reflects a derivative (pre-funded warrant) acquisition, not a sale.
Context
Pre-funded warrants are purchased now and can be exercised into shares later; here they carry an ownership cap to avoid crossing specified percentage thresholds. This filing documents acquisitions (purchases), which investors often view as a more meaningful sign than routine sales, but the Form 4 does not state the buyer’s motive. The F2 structure indicates the reported interest involves an investment vehicle/manager relationship rather than only a personal, direct holding.
