BillionToOne CEO Sells Entire Direct Stake for ~$3 Million
On September 14, 2026, BillionToOne's CEO Oguzhan Atay sold all of his directly held shares in the company—amounting to $3 million—as disclosed via an SEC Form 4 filing. The transaction included a cashless exercise and immediate sale of 24,999 stock options at a strike price of $2.80, as well as the disposal of 5,332 indirectly held shares from his spouse’s account. The CEO's move was executed under Rule 10b5-1 trading plans established in June 2026, which remove discretion and are often used to comply with insider trading regulations. Despite selling all directly owned stock, Atay still holds over half a million fully vested options and his spouse retains ~157,000 shares post-sale. BillionToOne remains financially strong, having reported $397.4 million in trailing twelve-month revenue and net income of $33.5 million as of September 2026.
