Context

• These entries reflect internal reorganization and distributions among affiliated Thrive Capital funds and conversions between Oscar Health’s Class B and Class A shares—not open-market buying or selling by an unrelated third party. As a 10% institutional holder and general partner reporting for multiple funds, this activity is administrative in nature (reclassifications and distributions) and should not be interpreted as a straightforward insider buy/sell signal by an individual executive. Joshua Kushner is identified in footnotes as the managing member with voting/investment power and has filed separate Section 16 disclosures where applicable.
