 II. Strategic Rationale  7 

 Healthcare costs are growing at unsustainable levels Healthcare spending is projected to grow 5.6% per year, on average, over the period 2016 – 2025 – a more rapid rate than growth in GDP – and increase to 19.9% of GDP by 2025 1At the same time, the health conditions of Americans are deterioratingNearly 150 million Americans are living with at least one chronic condition; around 100 million have more than one; and nearly 30 million are living with five chronic conditions or more 2Those with five or more conditions (about 12% of the U.S. adult population) account for more than 40% of U.S. health spending, which could translate into more than $1 trillion a year, based on current estimates of overall healthcare costs 2As early as 2030, roughly two of every five people age 65 or older will be living with three chronic conditions or more – an age group projected to make up a quarter of the U.S. population by 2060 (as compared to 15% today) 2Pharmacy is the most widely used healthcare benefit with prescription drugs representing a growing share of healthcare spendThe pharmacy benefit is used almost twice as frequently as the next closest healthcare benefit (relative to the number of transactions (or interactions) per member per year), and currently, constitutes about 20% of employer-based insurance benefits 3, 4Over the next decade, the Centers for Medicare and Medicaid Services (CMS) projects that spending for retail prescription drugs will be the fastest growth health category and will consistently outpace that of other health spending – rising an average of 6.3% per year, due to higher drug prices and more use of specialty drugs 5  The Current Healthcare Landscape is Unsustainable…   8  It has become crucial to manage drug and other medical costs holistically to reduce costs, preserve health and improve outcomes   Source: https://www.healthaffairs.org/doi/10.1377/hlthaff.2016.1627Source: https://www.rand.org/blog/rand-review/2017/07/chronic-conditions-in-america-price-and-prevalence.htmlSource: http://www.cms.hhs.gov/NationalHealthExpendDataSource: The High Cost of Prescription Drugs in the United States,A.

 III. Governance and Process   14 

 Cigna’s Consideration of the Transaction Was Thorough and Deliberate  15  Cigna’s Board and management team regularly evaluated potential strategic alternatives that might be available to Cigna, including consideration of industry and regulatory developmentsAfter the termination of the merger agreement with Anthem in May 2017, Cigna considered a number of potential strategic paths, including continued standalone operations, a large transformative business combination or pursuing a number of smaller acquisitionsAs part of this process, Cigna’s Board scrutinized hypothetical combinations with a number of other industry players, both in terms of financial profile and from the perspective of how Cigna might advance its strategy Cigna’s Board ultimately determined that a combination with Express Scripts was the most attractive option available to Cigna to meaningfully accelerate the transformation of the U.S. healthcare system and maximize long-term shareholder valueCigna’s Board conducted thorough deliberation over the course of many meetings Cigna’s Board discussed and reviewed extensively the standalone valuation of Express Scripts and the expected financial characteristics of the combined company, including the estimated synergies from a potential transaction, in each case under different scenarios Transaction terms arrived at via rigorous and independent negotiationsExchange ratio and cash consideration determined following a thorough negotiation process, supported by the totality of due diligence review of Express Scripts and expected synergiesShareholder approvalTransaction subject to approval by a majority of the outstanding shares of Cigna common stock  In the Board’s view, the acquisition of Express Scripts meaningfully accelerates Cigna’s strategy and maximizes long-term shareholder value 

 Joint integration team from both Cigna and Express Scripts is led by Cigna President & CEO David Cordani and Express Scripts President & CEO Tim WentworthEmploying a three-pronged approach: Culture alignment is key to the overall integration planUnderstanding the bright spots and vulnerabilitiesHave a multi-year, long-term view to the integration and value creationThe combined company will have three attractive, well-positioned growth platforms:Priority in the near-term is business continuity for both companies  Cigna’s Board, With Management, Has a Continued Focus on Long-term Shareholder Value Creation  16  U.S. Integrated Services PlatformNational scope targeting employers of all sizes, health plans and government agencies  U.S. Integrated Medical Targeting Cigna’s “Go Deeper” geographies  Global and Individual PlatformsLeading globally mobile, employer and individual solutions   Strong operational performance over the last 8 years111% revenue growth CAGR13% EPS growth CAGR14% average annual return on invested capital Expanded global customer relationships by 30+ millionStrong shareholder returns over the last 8+ years2384% cumulative total shareholder returnIndustry leading U.S. total medical cost trend Less than 3% in 2017  Cigna’s Proven Track Record in a Challenging Market  A Clear Roadmap for Successful Integration  1. 12/31/09 – 12/31/17; 2. 12/31/09-6/30/18 

 The Investment Community Believes the Combination with Express Scripts Will Drive Substantial Upside   17  “We see meaningful opportunity around the pending ESRX deal (ESRX, $78.39, Buy) which further integrates the crucial pharmacy benefit and should provide for deeper collaborative relationships. In addition, ESRX is posting historically low drug trend, superb customer retention and tangible cost benefits from higher penetration of its solutions. Finally, we see opportunity around clinical solutions (e.g. SafeGuardRx, TRCs), medical management (e.g. eviCore), synergies and cross-selling … We like the company’s integrated offering, attractive absolute/relative medical trends, strong cash flow and see meaningful opportunities on several fronts from the pending Express Scripts combination.” – David MacDonald, SunTrust (6/11/18)  “ESRX is a strategic platform acquisition for CI to drive industry leading total cost trend across medical and pharmacy, particularly with the increasing importance of Specialty Pharmacy. ESRX offers CI a combined platform at scale that can compete with the new Big 4: UNH with Optum Rx, ANTM with Ingenio Rx, and AET with CVS. The deal is not about CI’s outsourced relationship for its own membership, but as a broader imperative across all segments and geographies for Employer, Health plan and Government. Value based care discussions are now evolving from providers to outcomes based payments for drug manufacturers.” – Ana Gupte, Leerink (3/26/18)  “We are supportive of the [Cigna and Express Scripts] deal… We do understand, respect, and buy into the concept that if you have scale on the managed care side and scale on the pharmaceutical benefit management side, that through better data analytics you can actually lower the per member per month cost by, we think, $20 or 5% per member per month and since Cigna is mostly an ASO business that’ll mostly get passed onto customers. So this merger will actually be pro-competitive and pro-customer.” – Glenview Capital CEO Larry Robbins, a Cigna and Express Scripts investor,in a CNBC interview (4/23/18)  “Nevertheless, the accretion from this deal is highly compelling, projected in the double-digit percentages in Year 1. Longer-term, Cigna continues to project $20-21 in EPS by 2021. This would leave the stock at just 8-9X that pro forma EPS forecast, leaving significant wiggle room for the company to fail to meet its expectations. The company's outlook assumes merely cost synergies, but investors could be overlooking the potential upside opportunities. Cigna's core health insurance business should be improved due to the integrated benefit offering and the opportunity to target new customers. In fact, the companies overlap in only ~30% of markets, suggesting there could be a significant opportunity to grab market share for each business … Overall, we believe the market's pessimism about the deal would ultimately prove to be unwarranted if the deal does go through.” – Michael Wiederhorn, Oppenheimer (6/12/18)    Note: Permission to use quotes was not sought or obtained; Source: Wall Street Analyst Research Reports  

 There Has Been Increased Conviction in the Transaction Closing as the Market Better Understands Potential Value Creation   18  The announcement surprised the marketplaceNo prior speculation of an Express Scripts transaction Investors may have been expecting Cigna to pursue a different large-scale transaction Many times, acquirers underperform post-announcementAmong other factors, an ongoing DOJ review has some investors reluctant to commit capital pending greater certainty  “However, if this comes to pass, we would expect CI to outperform the peers once deal closing comes into clarity as the deal has strategic merits, is financially attractive and CI is trading at a significant discount to peers.”– Kevin Fischbeck, BAML (3/9/18)  Potential Drivers of Initial Market Reaction  Views on Future Valuation Prospects  UNH – a peer with an integrated MCO and PBM business model – trades at the highest multiple in the MCO group  “Cigna trades at 12.0x our 2019E EPS, a meaningful discount to the group tied largely to what we view as underappreciated value from the pending ESRX acquisition. We view CI’s risk/reward as highly compelling tied to robust core trends, strong cash flow and what we expect to be significant benefits from ESRX.” – David MacDonald, SunTrust (6/11/18)  “We continue to believe that CI may be range bound until we get closer to deal closure at year end, but see significant upside potential over the next 12 months.”– Kevin Fischbeck, BAML (6/12/18)  Note: Permission to use quotes was not sought or obtained; Source: Wall Street Analyst Research Reports  This integrated business model is being pursued by other market participants, such as Aetna/CVS Caremark and Anthem/Ingenio RxCombined company will serve integrated health solutions – medical, behavioral and specialty insights (Cigna) with broad pharmacy, specialty pharmacy and clinical insights (Express Scripts) – to more than 100 million customers
