About Oak Street Health, Inc.

Oak Street Health, Inc. is a U.S. healthcare company focused on primary care for Medicare-eligible adults. It was founded in 2012 in Chicago, Illinois, and became known as a value-based care platform built around senior-focused primary care centers. The business is historically associated with the NYSE under the ticker OSH, although today it sits within CVS Health’s broader healthcare delivery platform. For investors, the key point is that Oak Street Health is not a traditional hospital or urgent care operator; it is a primary-care-led model designed to manage patient health proactively, with an emphasis on prevention, care coordination, and clinical outcomes rather than visit volume. At the core of the model are neighborhood-based primary care centers serving older adults, especially Medicare beneficiaries. Oak Street Health’s services include routine primary care, chronic disease management, preventive screening, care navigation, and coordination with specialists and other parts of the care continuum. Its care model is differentiated by longer appointments, multidisciplinary teams, and a strong focus on social and behavioral health integration. That positioning places the company in the fast-growing U.S. value-based care segment, where providers seek to improve outcomes while lowering avoidable hospitalizations and emergency department utilization. Oak Street Health was one of the more visible independent primary care rollouts in the U.S. before being brought into CVS Health. It expanded quickly across multiple states and reached major milestones such as opening its 100th center in 2021. That pace of expansion highlighted both the scalability of the model and the company’s strategy of building density in markets with large Medicare populations. Its competitive position has historically rested on brand recognition in senior care, a highly disciplined operating model, and its ability to align with Medicare Advantage and other risk-based reimbursement structures. Recent developments should be interpreted through the lens of CVS Health ownership. CVS has continued to describe Oak Street Health as part of its effort to create a more integrated healthcare offering, combining physical, behavioral, and social care within a prevention-oriented primary care model. Recent CVS communications also reinforce the strategic importance of Medicare Advantage as a reimbursement vehicle supporting Oak Street’s approach. For market observers, the main issues are the economics of risk-bearing primary care, the sensitivity to Medicare reimbursement and medical cost trends, and CVS’s execution in turning Oak Street Health into a durable, scalable platform. In short, Oak Street Health is a U.S. NYSE-listed heritage healthcare brand with a strong primary care franchise and a clear strategic role inside CVS Health.
