CVS Health to Split Into Two Companies by 2028 as Pharmacies Separate From Aetna and Caremark

Introduction

CVS Health, one of the largest healthcare companies in the United States, has announced that it intends to split into two independent, publicly traded companies, separating its retail pharmacies from its Aetna health insurance business and its Caremark pharmacy benefit operations. The company said on November 4, 2026, that the separation is expected to be completed in the first half of 2028, ending a vertically integrated structure it spent years building through a series of major acquisitions. The decision follows a comprehensive strategic review by the CVS Health board of directors, and it marks one of the biggest corporate breakups in American healthcare in recent years.

The announcement came alongside the company’s third-quarter results, and it immediately reshaped how investors, patients, employers and policymakers think about a business that touches tens of millions of Americans through its drugstores, its insurance plans and its prescription drug benefits. One company will keep the CVS Health name and hold the insurance, pharmacy benefit and care delivery businesses, while the other, to be called CVS Pharmacy, will run about 9,000 retail pharmacies, the mail pharmacy, MinuteClinic and a technology services business. This is the story of the CVS Health split into two companies by 2028, with its pharmacies separating from Aetna and Caremark.

1. What CVS announced on November 4

On November 4, 2026, CVS Health said it intends to separate into two independent, publicly traded companies, each committed, in the company’s words, to innovating to make healthcare more affordable, accessible and simpler to navigate for the millions of people each serves. The announcement was made from the company’s headquarters in Woonsocket, Rhode Island, and it was described by the company as the outcome of a comprehensive strategic review by its board of directors. Reuters reported the same day that the move amounts to a major unwinding of the roughly 117 billion dollar healthcare conglomerate that CVS spent years assembling, and that the company’s shares fell after the news.

1.1 The two companies taking shape

The planned separation will create two companies with very different jobs. The first is a healthcare solutions company that will comprise Aetna, the health insurer; CVS Caremark, the pharmacy benefit manager; CVS Specialty; Oak Street Health, the primary care provider; and Signify Health, the in-home health business. In the interim, this company will be referred to as CVS Health. The second is a retail pharmacy and community healthcare company comprising approximately 9,000 CVS pharmacies, the mail pharmacy, MinuteClinic, including virtual care, and the Health100 technology services business. This company will be named CVS Pharmacy.

1.2 The timetable to the first half of 2028

CVS said the separation is expected to be completed in the first half of 2028, subject to customary conditions. Those conditions include final approval by the CVS Health board of directors, the effectiveness of a Form 10 registration statement filed with the United States Securities and Exchange Commission, and receipt of customary confirmation about the tax-free treatment of the separation for the company and its shareholders. The long runway matters because the split is not a simple paper exercise. It requires untangling shared systems, contracts, staff and data across businesses that have operated as one company for years, and investors face more than a year of separation costs and management attention before each business can be valued on its own.

2. How the businesses will divide

The dividing line in the split runs between the businesses that pay for and manage healthcare and the businesses that dispense medicines and see patients face to face. The healthcare solutions company keeps the insurance and benefits machinery, while CVS Pharmacy keeps the storefronts. That division is deliberate, because it puts the parts of CVS that negotiate drug prices and manage insurance risk on one side, and the parts that fill prescriptions and run clinics on the other.

2.1 The healthcare solutions company

The healthcare solutions company will bring together Aetna, CVS Caremark, CVS Specialty, Oak Street Health and Signify Health under the leadership of the current CVS Health chairman and chief executive. Aetna provides health insurance to millions of people, including through government programmes, while Caremark manages prescription drug benefits for employers, health plans and government programmes. Oak Street Health runs primary care centres, many of them serving older patients, and Signify Health carries out in-home health evaluations. Keeping these businesses together preserves the combination of insurance, pharmacy benefits and care delivery, which the company argues can coordinate a patient’s coverage, medicines and primary care more closely than any one of them could alone.

2.2 The new CVS Pharmacy

CVS Pharmacy will be a standalone retail pharmacy and community healthcare company built around about 9,000 CVS pharmacies, the mail pharmacy, MinuteClinic and the Health100 technology services business. Reports on the announcement said the retail company will employ nearly 30,000 pharmacists, a scale that underlines how large a standalone pharmacy business it will be. MinuteClinic, including virtual care, gives the new company a walk-in and online care presence inside and alongside its stores, while the mail pharmacy serves customers who receive their medicines by post. The split brings CVS back to being a standalone pharmacy chain for the first time since 2006, when it purchased the Caremark pharmacy benefit manager and began the journey toward vertical integration.

3. Who will lead each company

The announcement named the two executives who will lead the separated companies, and both are already senior figures inside CVS. The choice signals continuity rather than a clean break in leadership, with the current chief executive staying with the larger healthcare solutions business and the current group president taking charge of the pharmacy chain.

3.1 David Joyner and the healthcare solutions business

Upon separation, David Joyner, currently chairman and chief executive of CVS Health, will be the chairman and chief executive of the healthcare solutions company. Joyner has led CVS through a period in which its insurance and pharmacy benefit businesses recovered from earlier difficulties, and he told investors on the company’s earnings call that in the past two years the pharmacy chain, the Caremark pharmacy benefit manager and the Aetna health insurance business had made marked improvements, making the new structure possible. His case, in essence, is that the businesses are now strong enough to stand on their own, and that separating them will let each one focus on its own customers, its own costs and its own growth.

3.2 Prem Shah and the retail pharmacy business

Prem Shah, currently group president of CVS Health, will become the chief executive of CVS Pharmacy. Shah’s appointment puts a senior insider in charge of the retail business at a moment when American pharmacies face pressure from online rivals, changing reimbursement and the costs of running thousands of stores. His task will be to run a standalone pharmacy company whose fortunes depend on prescription volumes, front-of-store sales, clinic visits and the efficiency of its supply chain, without the cushion of an insurance business alongside it. The two leaders will each report to their own boards, and each company will set its own strategy, its own targets and its own capital plans.

4. Why CVS is splitting now

Corporate breakups rarely happen for a single reason, and the CVS split is no exception. The company pointed to its strategic review, but the announcement also landed in a political and market environment that has grown more sceptical of large, vertically integrated healthcare companies, and at a moment when CVS’s own businesses had stabilised enough to be separated without one of them collapsing.

4.1 The board’s strategic review

CVS said the decision followed a comprehensive strategic review by its board of directors. During the company’s earnings call on November 4, Joyner said the rationale for the split falls under four buckets, although the detailed framing of those buckets was still being explained to investors as the news spread. The underlying logic reported by analysts is familiar from other big corporate splits this decade. Companies that grew by combining different businesses are now being told by investors that the parts may be worth more, and may be run better, separately than together. The planned breakup is the latest in a series of major corporate splits this decade as companies look to simplify their operations and boost shareholder returns.

4.2 The end of the vertical integration bet

For years, CVS argued that owning the pharmacy, the insurer and the pharmacy benefit manager together would let it control costs, steer patients to its own stores and clinics, and coordinate care in ways rivals could not match. That argument built the conglomerate. The 2006 purchase of Caremark brought the pharmacy benefit manager inside the company. The 2018 acquisition of Aetna, worth about 69 billion dollars, added one of America’s largest health insurers. The split reverses that direction. It accepts that the integration that once looked like a strength has become a source of complexity, conflicting incentives and regulatory scrutiny, and that two focused companies may serve patients and shareholders better than one sprawling one.

5. What shareholders and investors get

For shareholders, the split is structured as a separation in which they end up owning both new companies. CVS said that upon completion, its shareholders will own shares in both companies, and that the separation is intended to be structured as tax-free to CVS Health and its shareholders for United States federal income tax purposes. That tax treatment, if confirmed, matters a great deal, because a taxable split could leave shareholders with a large bill on the value of the shares they receive.

5.1 Shares in both companies

Under the plan, existing CVS Health shareholders will receive shares in the separated CVS Pharmacy business while keeping their shares in the healthcare solutions company. The exact distribution ratio, the listing arrangements and the timing of the share distribution have not yet been set out in full, and they will be detailed in the Form 10 registration statement that must be filed with the Securities and Exchange Commission and declared effective before the separation can complete. Until then, CVS will continue to operate as it currently does and work toward its financial targets, according to reports on the announcement.

5.2 The market reaction and the 2027 forecast

Shares in CVS fell after the announcement, according to Reuters, a reaction that reflected both the scale of the change and the uncertainty about how the two businesses will perform apart. At the same time, the company gave investors a reason for confidence about the near term. It forecast 2027 adjusted earnings of at least 8.65 dollars per share, ahead of analysts’ estimates of 8.53 dollars per share. The announcement also came alongside third-quarter results showing a continued recovery in Aetna’s margins, with lower medical costs in its government business, according to trade reports. That recovery is an important part of the story, because Aetna’s performance had been a drag on the group, and its improvement is part of what made the board willing to separate the businesses now.

6. What the split means for patients and customers

The most important question for the millions of people who use CVS is what changes for them. In the short term, the company has said, very little. The separation is not expected to complete until the first half of 2028, and until then CVS will keep operating as it does today. Over the longer term, though, the split could change how pharmacies, insurers and pharmacy benefit managers deal with each other, and that could reach patients through prices, access and the services on offer.

6.1 At the pharmacy counter

For customers of the roughly 9,000 CVS pharmacies, the new CVS Pharmacy will be a company whose entire business is the store, the prescription and the clinic. Supporters of the split argue that a focused pharmacy company will invest more in its stores, its pharmacists and its MinuteClinics, because those are its only businesses rather than one part of a much larger group. Critics may ask whether a standalone pharmacy chain, without an insurer alongside it, will have the same bargaining power with drug makers and suppliers, and whether that could affect the prices customers pay. Those effects will only become clear once the two companies are operating independently and negotiating with each other at arm’s length.

6.2 For Aetna members and employers

For Aetna members and for the employers who buy Aetna medical cover alongside Caremark pharmacy benefits, the split keeps the insurer and the pharmacy benefit manager together in a single integrated company. That matters, because employers buying both services will still deal with one company for their medical and pharmacy benefits. Reports on the announcement noted that Aetna and Caremark will stay together, so the combination that many employers already buy remains intact. What changes is that the pharmacy benefit manager will no longer be part of the same group as the 9,000 CVS stores, which may alter how Caremark steers patients toward particular pharmacies and how it negotiates with rival pharmacy chains.

7. The regulatory and political backdrop

The CVS split does not happen in a vacuum. Pharmacy benefit managers and vertically integrated healthcare companies have faced growing political scrutiny in Washington, and the announcement landed as lawmakers were pressing for changes to how drug prices are set and how middlemen in the prescription drug chain are regulated. The company itself acknowledged that political pressure played a part in its thinking.

7.1 The Break Up Big Medicine Act

Joyner himself noted that the Break Up Big Medicine Act influenced the split, according to MedCity News. The legislation, backed by lawmakers who argue that large healthcare conglomerates should be broken apart, would force companies to separate their pharmacy benefit and insurance operations from their retail businesses. By announcing a voluntary split, CVS gets ahead of that pressure and shapes the separation on its own terms, choosing the timing, the dividing lines and the leadership, rather than having a structure imposed on it by law. Whether the voluntary split satisfies the lawmakers behind the bill remains to be seen, and the politics of the issue may continue to shape the final form of the separation.

7.2 The approvals still needed

The separation still needs final approval by the CVS Health board of directors, an effective Form 10 registration statement with the Securities and Exchange Commission, and confirmation of its tax-free treatment. Regulators may also examine the split, although a voluntary separation of this kind is generally less contentious than a merger. The company said the separation is intended to be tax-free, but that treatment must be confirmed, and the customary confirmation the company referred to will be an important milestone. Until those conditions are met, the split remains an intention rather than a completed fact, and the timetable to the first half of 2028 could shift if any of them takes longer than expected.

8. What remains unconfirmed and what to watch next

As with any announcement of this size, much remains to be decided. The broad shape of the two companies is clear, but the details that will determine whether the split succeeds for patients, employees and shareholders are still to come, and they will emerge over the next year as CVS files its registration statement, names its boards and sets out its plans in full.

8.1 Open questions

Several questions remain open. The exact distribution ratio for the new shares has not been announced, and neither has the full cost of the separation or the debt that each company will carry. The detailed financial statements for the two standalone businesses have not yet been published, so investors cannot yet judge each company’s earnings, margins and cash flow on its own. It is also unconfirmed how many of the roughly 9,000 pharmacies will remain open in the long term, what will happen to staff who work across both businesses, and whether the two companies will continue to work together under commercial agreements once they are independent. The effect on the prices patients pay for medicines is likewise unconfirmed, and will depend on negotiations that have not yet taken place.

8.2 What to watch next

The next milestones to watch are the filing of the Form 10 registration statement, which will set out the financial detail of both companies, the confirmation of the tax-free treatment, and the final board approval. Investors will also watch the 2027 earnings forecast and whether Aetna’s margin recovery continues, because the healthcare solutions company’s performance will shape how the market values it when it stands alone. Patients and employers should watch for any changes to pharmacy networks, drug formularies and clinic services as the separation approaches. And in Washington, the fate of the Break Up Big Medicine Act and other healthcare legislation will show whether CVS’s voluntary split has eased the political pressure on the industry or whether lawmakers push for more. Until the first half of 2028, the split is a plan with a timetable, and the test of it will be what the two new companies look like when they finally stand apart.

CVS Health’s decision to split into two companies closes a chapter in American healthcare that began with the Caremark purchase in 2006 and the Aetna deal in 2018, and it opens another in which the pharmacy and the insurer will have to prove themselves separately. The company says each business is now strong enough to stand alone, and that focus will serve patients and shareholders better than size. Whether that proves true will be decided not by the announcement, but by the prices patients pay, the service they receive in stores and clinics, and the results the two new companies report once they are independent.
