Abstract

For over a decade and for the foreseeable future, federal agencies have made efforts to promote value-based care through various incentive schemes, such as the recent “Regulatory Sprint to Coordinated Care.” Federal incentive schemes and other “macro tailwinds” have brought in private equity investors, especially in the context of primary care for Medicare beneficiaries. Oak Street Health and its private equity backers were pioneers in this space, applying buy-and-build strategies to create “next-generation” primary care networks “that focus largely or entirely on Medicare Advantage enrollees.” Although Oak Street Health persuasively established a workable “playbook” for private equity investment in value-based care, and forecasts have been favorable, the ultimate market viability of this value-based playbook hinges on whether or not private equity investors can locate corporate buyers. The market viability of such a strategy has now been reconfirmed by the acquisition of Oak Street Health by CVS Health (“CVS”), announced February 8, 2023, and closed May 2, 2023, especially given that the incentives and the efficiencies associated with this deal are likely to be applicable to large-scale vertically integrated “payvider” corporations more generally. This Recent Transaction Comment examines CVS’s acquisition of Oak Street Health to consider what factors might lead vertically integrated health care corporations to acquire value-based primary care networks in the future, and what knock on effects such acquisitions might have on future private equity buyouts in health care.

Background

Value-Based Payment Models

In the years since the 2010 passage of the Affordable Care Act, the Centers for Medicare and Medicaid Services (“CMS”) have spearheaded numerous initiatives to shift the United States health care system away from the traditional fee-for-service (“FFS”) payment model, and toward policies focused on “systematically reducing spending or improving quality.”Footnote 1 Policies intended to “transform U.S. health care from a system that incentivizes volume to one that rewards value” have in general been referred to as “value-based payment models,” “value-based purchasing,” and “value-based care.”Footnote 2

Aside from its quality of care component, the shift to value-based care is in large part motivated by the need to put Medicare and Medicaid dollars to the their best possible use, similar to health care fraud and abuse legislation such as the Stark law (“Stark”) and the anti-kickback statute (“AKS”).Footnote 3 For example, in 2021, it was predicted that the Medicare Trust Fund would be insolvent sometime between 2024 and 2026, and as of early 2023 these predictions have been extended out to 2028.Footnote 4 Much like the health care fraud and abuse laws as they were first enacted, value-based payment models seek to disincentivize business models that “contribute appreciably to the cost of Medicare and Medicaid program” or that otherwise present “a real threat to the [Medicare] program’s long-term solvency.”Footnote 5

Although some experts have commented that the transition to value-based payment models “has slowed in recent years,”Footnote 6 the Department of Health and Human Services (“HHS”) continues to roll out new initiatives to promote this transition, such as the 2018-2021 “Regulatory Sprint to Coordinated Care.”Footnote 7 Amid the 2018 roll out of that initiative, the CMS as well as the HHS’s Office of the Inspector General (“HHS-OIG”) issued Requests for Information regarding the possibility of establishing a Stark exception and AKS safe harbor for health care providers operating under certain value-based payment models.Footnote 8 The CMS and the HHS-OIG subsequently issued two Final Rules on the matter—made effective in 2021—which “introduce an entirely new framework for structuring permissible arrangements and affiliations between and among health care providers and payors” and which are “designed to play a central role toward innovating care coordination and health care payment models for years to come.”Footnote 9

Thus, protection from health care fraud and abuse laws has been offered up as a carrot to further encourage providers to shift away from FFS payment models, and towards value-based payment models.Footnote 10 Importantly, these protections reach pre-existing value-based enterprises including accountable care organizations (“ACOs”),Footnote 11 which are already benefiting from previous federal incentive schemes.Footnote 12 Accumulating incentives of this sort have led analysts like Bain & Company to predict that value-based care “will capture 15%–20% market share from traditional FFS providers in primary care by 2030, creating strong macro tailwinds and supporting further investment in the space.”Footnote 13 Although “progress has been uneven until now,” health care investors have taken increasing interest in value-based care due to federal initiatives like the 2018-2021 Regulatory Sprint to Coordinated Care as well as the broadcasted goals of federal agencies, such as the CMS’s stated goal “for all traditional Medicare beneficiaries to be in a care relationship with accountability for quality and total cost of care by 2030.”Footnote 14

Private Equity Investment

Due to federal initiatives to accelerate the transition to value-based care, “the adoption of value-based payment models has steadily grown over the past decade”—especially the adoption of risk-bearing capitated reimbursement models in the context of Medicare Advantage plans.Footnote 15 Private equity firms have entered this market by investing in “networks of primary care clinics that focus largely or entirely on serving [Medicare Advantage] enrollees.”Footnote 16 This is a value-based variation of the buy-and-build approach typical to private equity investment in the health sector, being that the health care industry’s “fragmented market segments and changing technolog[ies]” give ample space for private equity investors “to scoop up smaller companies, [and] to scale up” an initial platform company through sequential add-ons.Footnote 17

One upside for private equity investors is that “next-generation primary care models”Footnote 18 of this sort can be profitable under full risk-bearing or substantially risk-bearing capitation contracts if the primary care network “operates efficiently, manages patients with chronic conditions well, and is able to report adequate quality metrics and extensively code patients’ comorbidities to drive higher risk-adjusted payments.”Footnote 19 This approach has been referred to as “the playbook of Oak Street Health”Footnote 20 because that company was an early pioneer in this space, having launched about a decade ago under private equity ownership.Footnote 21 Even aside from the prospect of the CMS “lean[ing] further into”Footnote 22 value-based payment models, “Medicare Advantage will continue to attract investment as the fundamentals of an aging population, rising enrollment, and large profit pools remain strong.”Footnote 23 As such, Bain & Company “expect to see continued investment in risk-bearing models across specialties beyond primary care and in segments beyond Medicare.”Footnote 24

Of course, the continued momentum of value-based care—and consequently, the continued market viability of private equity investment in value-based care—hinges on the federal government’s continued confidence that such activities truly do reduce spending or improve quality in the health sector, whether in aggregate or within specific sub-markets.Footnote 25 Health care commentators have had mixed reactions to private equity’s involvement in value-based care due to differing expectations regarding the ultimate outcomes associated with the “flood of fast-moving private capital”Footnote 26 brought in by private equity, which experts believe “aggressively amplifies” responses to financial incentives.Footnote 27 That is, aggressive amplification of well-aligned incentives “may well be favorable,”Footnote 28 while amplification of misaligned incentives “may simply funnel money to private investors while raising system costs.”Footnote 29

Under a flawless scheme of value-based care, private equity firms “should be expected to encourage investments and operational changes that support better health outcomes and lower costs, even if acting purely out of financial self-interest.”Footnote 30 But rational market actors should be expected to exploit “short-term arbitrage gains” where available, and if regulators are slow to adjust value-based pricing so as to close regulatory openings for arbitrage, such openings can become long term and “can bleed the system and weaken incentives to generate efficiency gains.”Footnote 31 However, despite such concerns, the existing public research literature on physician practice consolidation by private equity is “limited to industry reports, academic opinion pieces, and largely descriptive studies within single specialties.”Footnote 32 The few studies that purport to “address these gaps” typically focus on hospital-based physicians or specialty physician practices operating “within a largely fee-for-service delivery system” without squarely addressing the “separate mechanisms that are used by private equity firms to target . . . primary care practices operating under value-based payment arrangements.”Footnote 33

Moreover, conversations about the alignment or misalignment of financial incentives in the context of value-based payment models cannot focus solely on private equity firms because the activities of such firms and their affiliated private equity funds are always carried out in pursuit of an eventual sale.Footnote 34 The full set of financial incentives motivating private equity firms necessarily includes the market incentives given by prospective corporate buyers, and it appears that the likeliest corporate buyers of value-based primary care networks are vertically integrated “payviders” such as CVS.Footnote 35 This Recent Transaction Comment examines CVS’s acquisition of Oak Street Health to consider what factors might lead vertically integrated health care corporations to acquire value-based primary care networks in the future, and what knock on effects such acquisitions might have on future private equity buyouts in health care.

CVS Health’s acquisition of oak street health

Oak Street Health

The value-based primary care startup Oak Street Health was founded in 2012, opened its first clinic in 2013, and went public in 2020.Footnote 36 Private equity funds affiliated with the firms General Atlantic, LLC, and Newlight Partners, LP, were early investors in Oak Street Health.Footnote 37 Through their affiliate funds, General Atlantic and Newlight Partners were the “Lead Sponsors” for Oak Street’s initial public offering and retained a controlling stake immediately afterwards.Footnote 38 Specifically, the two private equity firms collectively held circa 52.4% to 52.9% of outstanding shares after Oak Street Health went public.Footnote 39 In addition, as a “controlled company” at listing, Oak Street’s prospectus disclosed the company’s intention to make use of exemptions from corporate governance practices that would otherwise be required, such as maintaining a majority of independent directors on its Board.Footnote 40

It appears that the main goal behind Oak Street’s $328 million offering was to secure financing, and the company’s CEO Mike Pykosz commented, “We want to continue to bring in more resources into the company so we can continue to execute our mission.”Footnote 41 At pricing, the estimated market value of Oak Street Health was roughly $5 billion, and the first day of market trading saw share prices rise from $21 to $43.47.Footnote 42 Although Oak Street’s initial public offering was likely driven by financing considerations, its newfound status as a public company came with disclosure requirements that heightened the visibility of its practices, especially relative to privately held value-based primary care networks such as Iora Health.Footnote 43

Heightened visibility is likely one reason why Oak Street Health is so frequently alluded to as a model of private equity investment in value-based primary care.Footnote 44 In its final prospectus, Oak Street Health reported that as of March 31, 2020, it had contracts with twenty-three Medicare Advantage payors and that 49% of its Q1 capitated revenues arose from its relationship with Humana.Footnote 45 The company reported steady historical growth in the number of patients for whom Oak Street Health’s services were paid on a capitated basis rather than FFS, increasing from circa 12,000 patients in 2016 up to about 55,000 patients by the end of Q1 in 2020.Footnote 46

Oak Street’s annual report for 2022 points to further increases, as the company ended 2020 with 64,500 patients on capitation contracts, ended 2021 with 114,500 patients on capitation contracts, and ended 2022 with 159,000 patients on capitation contracts.Footnote 47 Oak Street’s number of clinics and the number of states it services saw rapid scaling in the time between its public listing and its 2022 annual report, rising from 54 centers across 8 states in Q1 2020, to 169 centers across 21 states by end-of-year 2022.Footnote 48 Finally, both Medicare and Medicare Advantage remain absolutely essential to Oak Street’s business model: “revenues from Medicare accounted for 98%, 98% and 96% of our revenues for each of the years ended December 31, 2022, 2021 and 2020, respectively.”Footnote 49

CVS Health’s Acquisition

On February 8, 2023, Oak Street Health and CVS issued a joint press release announcing that the two companies had “entered into a definitive agreement” in which CVS would acquire Oak Street Health “in an all-cash transaction at $39 per share, representing an enterprise value of approximately $10.6 billion.”Footnote 50 General Atlantic, Newlight Partners, and certain members of the Board of Oak Street Health, “which collectively own approximately 45% of the common stock,” agreed to vote in favor of the deal.Footnote 51 According to Bloomberg Law, General Atlantic “[was] poised for a more than $3 billion windfall . . . with a more than 25% stake.”Footnote 52 Thereafter, CVS entered a term loan agreement on May 1, 2023, to borrow $5 billion to cover roughly half of the purchase price. Footnote 53 The deal closed on May 2, 2023.Footnote 54

The Oak Street deal is CVS’s largest since its 2018 acquisition of the health insurer Aetna for $68 billion.Footnote 55 CVS executives foreshadowed their interest in a primary care acquisition on a mid-2022 earnings call, following CVS’s announced acquisition of value-based home care platform Signify Health for $8 billion.Footnote 56 Acquiring Oak Street Health and Signify Health in short succession amounts to a $20 billion gallop into Medicare driven value-based care, and in the context of CVS’s previous acquisition of Aetna, reflects CVS’s ambitions to become a large-scale vertically integrated “payvider” similar to the model set by UnitedHealth Group’s expansion into health care via Optum.Footnote 57

Specifically, a “payvider” is what results when a payer or health insurer enters into a vertical merger or joint venture with a health care provider, and the term has gained traction as “giant corporations such as Amazon, CVS, Walgreens, and Walmart have aimed to disrupt health care and large payers, such as Aetna and Humana, are moving into the primary care space.”Footnote 58 One reason that vertical integration is appealing to businesses is because successful antitrust challenge is highly unlikely,Footnote 59 and here, CVS’s acquisition of Oak Street Health did not receive a second look under Hart-Scott-Rodino pre-merger review.Footnote 60 The “payvider” approach has gained traction recently, especially in primary care, because such entities are better able to control costs and are well-positioned to benefit from the transition to value-based care.Footnote 61

“Payvider”-style arrangements are not new, given that “examples go back at least to the 1980s when insurers like Aetna, Cigna, and Humana employed physicians as part of their HMO offerings,” although “most insurers eventually divested their physician practices.”Footnote 62 Even while such arrangements saw a period of decline, exceptions such as Kaiser Permanente in California “championed the model with great success for decades.”Footnote 63 More recently, however, “payvider” arrangements have proliferated again in the Medicare context, including joint ventures between providers and payors such as Banner Health and Aetna, or Agilon and Humana.Footnote 64 The “payvider” label has particular salience in the context of vertical integration between primary care platforms and Medicare Advantage plans; as far back as 2013, “about 17% of Medicare Advantage plans were integrated with providers.”Footnote 65

Importantly, “acquisition of primary care practices by insurers has significant potential to shift incentives towards reducing healthcare spending” because lower spending on health care by insurers decreases marginal costs, which “can increase profit margins holding premiums fixed[,] or result in greater customer volume for the insurer (and savings to customers) if some of the reduced spending is passed through in the form of lower premiums.”Footnote 66 Vertically integrated “payviders” may have a uniquely powerful incentive to reduce premiums “because integration makes gaining additional enrollees (e.g., by lowering premiums) more profitable: each additional enrollee brings both an insurer-level and a provider-level profit margin, whereas without integration the insurer gains only the insurer-level profit margin.”Footnote 67

If the prospect of greater gains per head in capitation contracts truly leads “payviders” to redirect savings from reduced health care spending to the lowering of insurance premiums as a method of enrollee recruitment, then vertical integration would readily comport with value-based initiatives because “payviders” would reduce spending while simultaneously receiving greater benefit from federal incentive schemes.Footnote 68 Direct vertical integration brings the added benefit of reducing the transaction costs brought about by “the challenge of writing complex, complete contracts that reliably define quality of care and allow for measurement of quality in a way that is transparent and that both providers and insurers agree is appropriate.”Footnote 69

As previously discussed, there are also purely demographic reasons to expect value-based care to succeed: “Medicare Advantage will continue to attract investment as the fundamentals of an aging population, rising enrollment, and large profit pools remain strong.”Footnote 70 A month and a half after the Oak Street deal was announced, CVS CEO Karen Lynch publicly characterized these trends as representing an oncoming “tsunami” of Medicare enrollment.Footnote 71 Moreover, CVS’s sharp focus on preventive care—emphasizing “early detection of chronic conditions” and “integrating health care technology in the home”—reflects intentions to leverage the at-home health care offerings of Signify Health to yield improved outcomes on capitated contracts.Footnote 72 In another contemporaneous talk, Lynch described CVS’s focus on Medicare Advantage as follows: “That’s the largest population, has the highest cost, has the most chronic conditions. We feel like we can have a huge impact on improving overall health outcomes in that population.”Footnote 73

Finally, perhaps the greatest testament to the continuing interest of CVS and similar large-scale vertically integrated “payviders” in purchasing value-based primary care networks built up by private equity is the rapid pace of dealmaking in this area.Footnote 74 CVS considered buying value-based primary care Cano Health shortly before deciding on Oak Street,Footnote 75 whereas Amazon, UnitedHealth Group, and Option Care Health all considered extending an offer to Signify Health before CVS became its final buyer.Footnote 76 Similarly, Amazon’s 2023 announcement that it will acquire One Medical—which very recently acquired Iora Health, a value-based primary care network extremely similar to Oak Street HealthFootnote 77—demonstrates Amazon’s earnest interest in breaking into the market, even if Amazon is not yet a firmly established player in health care.Footnote 78 While demographic fundamentals and federal incentives undergird favorable forecasts as to the future of value-based care, the particular example of CVS’s acquisition of Oak Street Health serves to reconfirm the market viability of private equity investment in value-based payment models of primary care, especially in the context of the rapid pace of dealmaking among other “payviders” and aspiring “payviders.”
