Oscar Health, Inc. reported an insider ownership change involving William Gassen, a member of the company’s board of directors. The Form 4, filed July 13, 2026, reports a transaction dated July 9, 2026 involving deferred stock units tied to Oscar Health’s Class A common stock. According to the filing, Gassen elected under Oscar Health’s Amended and Restated Deferred Compensation Plan for Directors to receive deferred stock units instead of cash retainer payments for board service. Each deferred stock unit represents the right to receive one share of the company’s Class A common stock. The filing describes the units as derivative securities. The deferred stock units issued in lieu of the cash retainer were fully vested on the grant date. The number of units was calculated using the closing price of Oscar Health’s Class A common stock on July 9, 2026, though the provided filing text does not show the exact unit count, transaction code, reported price, or post-transaction ownership total. Settlement of the deferred stock units may occur in either cash or shares of Class A common stock, at Oscar Health’s discretion. The units are to be settled within 45 days after the first of several events: Gassen’s termination of service, a change in control of the company, death, or disability. The filing was signed on Gassen’s behalf by Melissa Curtin, attorney-in-fact, on July 13, 2026. The reported action reflects compensation-related equity deferral rather than an open-market purchase or sale.
