BillionToOne (BLLN) CEO Atay Oguzhan Converts and Gifts 40,000 Shares

What Happened

• Atay Oguzhan, Chairman and CEO of BillionToOne (BLLN), reported conversions of Class B shares into Class A common stock and a subsequent gift. The Form 4 shows two conversion entries on 2026-09-08 (20,000 shares reported as acquired at $0.00; a separate 20,000-share conversion reported as a derivative disposal at $0.00) and a gift of 20,000 shares on 2026-09-09 (disposed, $0.00).
• All conversion entries list a $0.00 price because they reflect share-class conversions (not cash purchases or open-market trades). Based on the reported transactions, the filings show a net reported change of -20,000 shares (20,000 acquired, 40,000 disposed across the two disposals).

  • The filing notes automatic conversion rules for Class B into Class A under certain conditions (see filing footnotes).
• Filing timeliness: Form filed on 2026-09-10 for transactions on 2026-09-08 and 2026-09-09 — appears to be filed within the typical two-business-day Form 4 window.

Context

• Conversions at $0.00 mean the insider exercised conversion rights to change share class, not a cash purchase or sale. Such conversions are administrative and don’t by themselves signal buy/sell sentiment.
• The 20,000-share disposal labeled as a "Gift" is a non-market transfer and generally should not be read as a signal of insider confidence.
