The Acquisition Playbook.

Three patterns run through UNITEDHEALTH's acquisitions — what it looks for, how it pays, and how it folds in what it buys.

01
Acquisition criteria
Build Optum by buying the care-delivery layer.
Roughly half of these deals fed Optum's ambulatory, in-home and primary-care platform - Surgical Care Affiliates and DaVita Medical Group into OptumCare, then LHC Group, naviHealth, Landmark Health and Amedisys into in-home and post-acute care. The through-line is value-based care: Optum repeatedly paid to own the providers and care-management assets that let it manage risk rather than just pay claims.

02
Capital deployment
Own the pipes and the data, not just the risk.
UnitedHealth used M&A to control health care's transactional and information infrastructure - Catamaran built OptumRx into a top-three PBM, Genoa added behavioral-health pharmacy, Equian added payment integrity, and the $13.9 billion Change Healthcare acquisition folded the industry's clearinghouse and revenue-cycle backbone into OptumInsight after an extended DOJ antitrust fight.

03
Integration approach
Expand the benefits franchise by geography, then go international.
The earliest large deals were classic health-plan consolidation - Oxford (Northeast), PacifiCare (West and Medicare/Secure Horizons) and Sierra Health (Southwest) - broadening UnitedHealthcare region by region. UnitedHealth then extended the model abroad with Amil in Brazil (2012) and Empresas Banmedica across Chile, Colombia and Peru (2017), before later retrenching from Brazil.
