Overview
- Governor Gavin Newsom signed AB 1415 on October 11, 2025, with the law taking effect January 1, 2026.
- AB 1415 creates a new category of “noticing entities,” covering private equity groups, hedge funds, MSOs, newly formed deal vehicles, and entities that own or operate providers.
- Transactions within scope require pre‑closing notice to the Office of Health Care Affordability, which may conduct Cost and Market Impact Reviews that can delay closings.
- The statute does not grant OHCA authority to block transactions, but it broadens the universe of deals subject to review and information requests.
- Implementing rules are pending, including clarity on thresholds and filing formats, and the move follows SB 351’s recent codification of corporate practice restrictions with Attorney General enforcement.
