On October 11, 2025, Governor Gavin Newsom signed into law Assembly Bill 1415 (“AB 1415”), which amends the California Health Care Quality and Affordability Act (the “Act”) to require pre-transaction clearance and data reporting from private equity groups, hedge funds, and management services organizations (“MSOs”), and certain other entities involved in healthcare transactions. Effective January 1, 2026, the law represents a significant expansion of the authority of the California Office of Health Care Affordability (“OHCA”), which already has broad review power over transactions involving many different provider and payor entities.
