Editing Vertical integration (section)

===Health care===
Within healthcare systems, horizontal integration is generally much more prominent. However, in the United States, major vertical mergers have included [[CVS Health]]'s purchase of [[Aetna]], and [[Cigna]]'s purchase of [[Express Scripts]]. The integration of CVS Health and Aetna resulted in the combination of one of the nation's largest health insurance companies with a pharmaceutical company seen all across the U.S. The vertical merge allowed CVS-Aetna to regulate more of the healthcare and delivery chain and gave them the ability to provide higher quality care to consumers. One of the most significant advantages to this integration is the reduction in costs for healthcare.<ref>{{Cite journal |last1=Kish |first1=Natalie |last2=Bhagat |first2=Maulik |date=2018-02-26 |title=CVS-Aetna: A blockbuster in vertical integration |journal=Chain Drug Review |volume=40 |issue=4 |pages=17–18}}</ref>{{citation needed|date=October 2024}}
