What Happened
Behbahani Ali (reported as a 10% owner / manager of related NEA vehicles) acquired a total of 450,045 Korro Bio (KRRO) securities on March 10, 2026 via a subscription with the issuer. The filing shows two acquisitions at $11.11 per share: 207,100 common shares for $2,300,881 and 242,945 pre‑funded warrants (derivative) for $2,698,876 — total consideration ~$4,999,757. Both items are reported as grants/awards (transaction code A), i.e., acquisitions rather than sales.
Key Details
- Transaction date: March 10, 2026; Form 4 filed March 12, 2026 (timely filing).
- Prices and amounts: 207,100 shares @ $11.11 = $2,300,881; 242,945 pre‑funded warrants @ $11.11 = $2,698,876.
- Total acquired: 450,045 securities; total value ≈ $5.0M.
- Shares owned after transaction: not specified in the filing.
- Footnotes of note:
- F1: Acquired pursuant to a Subscription Agreement dated March 9, 2026.
- F2: Reporting person is a manager of NEA 17 GP, LLC (institutional vehicle); the filing disclaims beneficial ownership of portions held by NEA 17 where the reporting person has no pecuniary interest.
- F3: The pre‑funded warrants are exercisable any time but contain a cap preventing exercise that would push ownership above 9.99% (adjustable to up to 19.99% with advance notice).
Context
- This was an acquisition (purchase/subscription), which is generally regarded as a clearer insider signal than a sale, but filings are factual disclosures only.
- One line item is a derivative (pre‑funded warrant): these are effectively near‑term exercises that become common shares upon satisfaction of the warrant terms and are subject to ownership caps noted above.
- The filing ties the transaction to an institutional vehicle (NEA), so this appears to be an institutional subscription rather than routine open‑market trading by a company executive.
