NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Summary of significant accounting policies

Our significant accounting policies, normally included in financial statements prepared in conformity with generally accepted accounting principles, have been omitted from this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). We believe the disclosures contained in this Form 10-Q are adequate to fairly state the information when read in conjunction with the Notes to the Consolidated Financial Statements included in our consolidated financial statements for the year ended December 31, 2016 , included in Item 8 - Consolidated Financial Statements and Supplementary Data, included in our Annual Report on Form 10-K filed with the SEC on February 14, 2017 . For a description of our accounting policies, refer to the Notes to the Consolidated Financial Statements included therein.

We believe the accompanying unaudited consolidated financial statements reflect all adjustments (consisting of only normal recurring adjustments) necessary to state fairly the unaudited consolidated balance sheet as of June 30, 2017 , the consolidated balance sheet as of December 31, 2016 , the unaudited consolidated statement of operations and unaudited consolidated statement of comprehensive income for the three and six months ended June 30, 2017 and 2016 , the unaudited consolidated statement of changes in stockholders' equity for the six months ended June 30, 2017 , and the unaudited consolidated statement of cash flows for the six months ended June 30, 2017 and 2016 . Operating results for the three and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 .

New accounting guidance . In August 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The guidance addresses the classification of cash flow related to (1) debt prepayment or extinguishment costs, (2) settlement of zero-coupon debt instruments or other debt instruments with coupon rates that are insignificant in relation to the effective interest rate of the borrowing, (3) contingent consideration payments made after a business combination, (4) proceeds from the settlement of insurance claims, (5) proceeds from the settlement of corporate-owned life insurance, including bank-owned life insurance, (6) distributions received from equity method investees and (7) beneficial interests in securitization transactions. The guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The guidance will generally be applied retrospectively and is effective for financial statements issued for annual reporting periods beginning after December 15, 2017. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash. This guidance requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance will be applied retrospectively and is effective for financial statements issued for annual reporting periods beginning after December 15, 2017. We are currently evaluating the impact of these standards on our consolidated statement of cash flows.

In March 2016, FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends Accounting Standards Codification ("ASC") Topic 718, Compensation – Stock Compensation. The new standard simplifies the accounting for stock-based compensation, including amendments on how both taxes related to stock-based compensation and cash payments made to taxing authorities are recorded, changing the threshold to qualify for equity classification and allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur. Excess tax benefits were historically recorded in additional paid-in capital. Upon adoption on January 1, 2017, excess tax benefits, which are immaterial for the three and six months ended June 30, 2017 , are prospectively recognized as income tax expense on our consolidated statement of operations and prospectively recognized as an operating activity on our consolidated statement of cash flows for the six months ended June 30, 2017 . Prior periods have not been retrospectively adjusted for adoption of this standard. We have also elected to continue to estimate the number of awards that are expected to vest. The remaining amendments to this standard, as noted above, are either not applicable or do not change our current accounting practices and thus do not impact our consolidated financial statements, including our consolidated statement of cash flows.

In February 2016, FASB issued ASU 2016-02, Leases (ASC Topic 842), which supersedes ASC Topic 840, Leases. This ASU is intended to increase transparency and comparability of organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new guidance is effective for financial statements issued for annual reporting periods beginning after December 15, 2018, and early application is permitted. We are currently evaluating the impact of this standard on our consolidated financial statements.

Table of Contents

In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC Topic 606), which supersedes ASC Topic 605, Revenue Recognition. The new standard requires companies to recognize revenues upon transfer of goods or services to customers in amounts that reflect the consideration which the company expects to receive in exchange for those goods or services. In July 2015, the FASB delayed the effective date of the standard by one year. The new guidance is effective for financial statements issued for annual reporting periods beginning after December 15, 2017. We have substantially completed evaluation of our PBM segment and have determined adoption of the new standard will not have a significant impact on our PBM segment. We continue to evaluate the impact of this standard on our Other Business Operations segment and expect to complete our evaluation by the third quarter of 2017. We anticipate full retrospective application upon adoption.

Note 2 - Fair value measurements

Authoritative guidance regarding fair value measurement establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices for similar assets and liabilities in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.

Cash and cash equivalents include cash and investments in AAA-rated money market mutual funds with original maturities of less than 90 days . Cash and cash equivalents are stated at cost, which approximates fair value. These investments are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices in active markets. The fair values of accounts receivable, claims and rebates payable and accounts payable approximate carrying values due to the short-term maturities of these instruments.

Financial assets accounted for at fair value on a recurring basis include trading securities (included in other assets and consisting primarily of mutual funds) of $28.1 million and $29.9 million as of June 30, 2017 and December 31, 2016 , respectively. These assets are carried at fair value based on quoted prices in active markets for identical securities (Level 1).

The fair value, which approximates the carrying value, of our 2015 five-year term loan (Level 2) (as defined in Note 5 - Financing ) was estimated using the current market rate for debt with a similar maturity. The fair values of our senior notes are $12,764.2 million and $13,041.4 million as of June 30, 2017 and December 31, 2016 , respectively. See Note 5 - Financing for further discussion of the carrying values of our debt. The fair values of our senior notes were estimated based on observable market information (Level 2). In determining the fair values of liabilities, we took into consideration the risk of nonperformance. Nonperformance risk refers to the risk the obligation will not be fulfilled and affects the value at which the liability would be transferred to a market participant. This risk did not have a material impact on the fair values of our liabilities.

Note 3 - Goodwill and other intangible assets

Following is a summary of our goodwill and other intangible assets for our two reportable segments, Pharmacy Benefit Management ("PBM") and Other Business Operations.



	June 30, 2017							December 31, 2016
(in millions)	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount

	75.3		(49.8		)	25.5		75.1		(46.5		)	28.6
Total other intangible assets	$	18,026.1	$	(9,962.2	)	$	8,063.9	$	17,880.9	$	(9,244.0	)	$	8,636.9


(1)	Changes in the gross carrying amount of PBM customer contracts, trade names, and miscellaneous intangible assets represent the acquisition of myMatrixx Holdings, Inc. in May 2017. The acquisition is not material to our consolidated financial statements.


(2)	Changes in the gross carrying amount of PBM miscellaneous intangible assets and related accumulated amortization also reflect the write-off of fully depreciated assets.

Following is a summary of the change in the net carrying value of goodwill by reportable segment:



(in millions)	PBM		Other Business Operations		Total
Balance at December 31, 2016	$	29,180.4	$	97.4	$	29,277.8
Acquisitions (1)	146.9		-		146.9
Foreign currency translation	0.8		-		0.8
Balance at June 30, 2017	$	29,328.1	$	97.4	$	29,425.5


(1)	Represents the acquisition of myMatrixx Holdings Inc. in May 2017. The acquisition is not material to our consolidated financial statements.

The aggregate amount of amortization expense of other intangible assets was $364.1 million and $463.7 million for the three months ended June 30, 2017 and 2016 , respectively, and $726.5 million and $907.0 million for the six months ended June 30, 2017 and 2016 , respectively.

Included in total amortization expense is $55.4 million for both the three months ended June 30, 2017 and 2016 and $110.8 million and $89.7 million for the six months ended June 30, 2017 and 2016 , respectively, related to our 10 -year contract with Anthem, Inc. ("Anthem") to provide PBM services to members of the affiliated health plans of Anthem, which amounts are included as an offset to revenues. When we executed our agreement with Anthem in 2009, we considered the overall structure of the agreement and the nature of our relationship with Anthem, including the complexity of the service level required, and attributed a reasonable likelihood of renewal at the end of its term in 2019. Accordingly, we amortized the agreement using a modified pattern of benefit over an estimated useful life of 15 years . However, due to the sequence of events regarding our discussions with Anthem, culminating in the filing of a lawsuit by Anthem on March 21, 2016, we felt it prudent to consider the increased likelihood of either non-renewal or renewal on substantially different terms such that, beginning in March 2016, we began amortizing our agreement with Anthem over the remaining term of the contract (i.e., using a life of 10 years from the time the agreement was executed in 2009). Previously, we amortized the agreement over 15 years . Therefore, the intangible asset amortization associated with the Anthem agreement will run through the remaining term of the contract at the end of 2019, reducing the previous amortization period by 5 years . This change increased intangible asset amortization by

Table of Contents

$10.5 million for the first quarter of 2016 and by approximately $32.0 million per quarter beginning in the second quarter of 2016.

The weighted-average amortization period of intangible assets subject to amortization is 15 years, and by major intangible asset class is 8 to 20 years for customer-related intangible assets, 6 to 10 years for trade names (excluding legacy Express Scripts, Inc. ("ESI") trade names which have an indefinite life), and 5 years for miscellaneous intangible assets.

Note 4 - Earnings per share

Basic EPS is computed using the weighted-average number of common shares outstanding during the period. Diluted EPS is computed in the same manner as basic EPS, but adds the number of additional common shares that would have been outstanding for the period if the dilutive potential common shares had been issued. All shares are calculated under the "treasury stock" method. Following is the reconciliation between the number of weighted-average shares used in the basic and diluted EPS calculations:



	Three Months Ended June 30,		Six Months Ended June 30,
(in millions)	2017	2016	2017	2016
Weighted-average number of common shares outstanding during the period-basic	582.9	631.3	591.9	638.1
Dilutive common stock equivalents: (1)

(1)

All senior notes are redeemable prior to maturity at a price equal to the greater of (1) 100% of the aggregate principal amount of any notes being redeemed; or (2) the sum of the present values of the remaining scheduled payments of principal and interest on the notes being redeemed discounted to the redemption date on a semiannual basis (assuming a 360 -day year consisting of twelve 30 -day months) at the treasury rate plus the basis points as indicated, plus in each case, unpaid interest on the notes being redeemed accrued to the redemption date.


(2)	All senior notes are jointly and severally and fully and unconditionally (subject to certain customary release provisions, including sale, exchange, transfer or liquidation of the guarantor subsidiary) guaranteed on a senior unsecured basis by Express Scripts (if issued by either Medco or ESI) and by most of our current and future 100% owned domestic subsidiaries.


(3)	Senior notes require interest to be paid semi-annually, commencing six months subsequent to issuance.


(4)	Senior notes require interest to be paid semi-annually in March and September.


(5)	The 2015 five-year term loan (as defined below) had average interest rates of 2.26% and 1.80% as of June 30, 2017 and December 31, 2016 , respectively.

Bank credit facilities. In April 2015, we entered into a credit agreement (the " 2015 credit agreement ") providing for a five -year $2,000.0 million revolving credit facility (the " 2015 revolving facility ") and a five -year $3,000.0 million term loan (the " 2015 five-year term loan "). At June 30, 2017 , no amounts were outstanding under the 2015 revolving facility . We make quarterly principal payments on the 2015 five-year term loan . At June 30, 2017 , $300.0 million of the 2015 credit agreement, and a proportionate amount of unamortized financing costs, was considered current maturities of long-term debt.

The 2015 credit agreement requires interest to be paid, at our option, at LIBOR or an adjusted base rate, plus applicable margin. Depending on our consolidated leverage ratio, the applicable margin over LIBOR ranges from 0.900% to 1.300% for the 2015 revolving facility and 1.000% to 1.500% for the 2015 five-year term loan . The applicable margin over the adjusted base rate ranges from 0.000% to 0.300% for the 2015 revolving facility and 0.000% to 0.500% for the 2015 five-year

Table of Contents

term loan . We are required to pay commitment fees on the 2015 revolving facility , which range from 0.100% to 0.200% of the revolving loan commitments, depending on our consolidated leverage ratio.

We have two additional credit agreements, each providing for an uncommitted revolving credit facility: $150.0 million executed August 2015 and amended most recently in May 2017 with a termination date of May 2018, and $130.0 million executed May 2017 with a termination date of May 2018. At June 30, 2017 , no amounts were drawn under either facility. In April 2017, we terminated a separate $130.0 million uncommitted revolving credit facility executed December 2014 and amended October 2015 and April 2016.

Covenants. Our bank financing arrangements and senior notes contain certain customary covenants that restrict our ability to incur additional indebtedness, create or permit liens on assets and engage in mergers or consolidations. The covenants related to bank financing arrangements also include, among other things, a maximum leverage ratio. The 7.125% senior notes due March 2018 issued by Medco are also subject to an interest rate adjustment in the event of a downgrade in our credit ratings to below investment grade. At June 30, 2017 , we were in compliance with all covenants associated with our debt instruments.

Note 6 - Income taxes

We recognized net discrete benefits of $20.2 million and charges of $9.7 million for the three and six months ended June 30, 2017 , respectively, compared to net discrete benefits of $13.8 million and $33.5 million for the same periods in 2016 . Our 2017 net discrete tax items primarily relate to a revaluation of our net deferred tax attributes. Our 2016 net discrete benefits primarily relate to changes in our unrecognized tax benefits.

Note 7 - Common stock

Under our share repurchase program, we repurchased 18.5 million shares for $1,154.8 million during the three months ended June 30, 2017 and 31.8 million shares for $2,057.4 million during the six months ended June 30, 2017 (including 0.6 million shares for $37.4 million that were repurchased but not settled as of June 30, 2017 ). We repurchased 2.8 million shares for $211.0 million for the three months ended June 30, 2016 and 48.5 million shares for $3,585.2 million during the six months ended June 30, 2016 . As of June 30, 2017 , there were 47.4 million shares remaining under our share repurchase program. Share repurchases made during the three and six months ended June 30, 2017 were made pursuant to a Rule 10b5-1 plan implemented on February 15, 2017 as well as through open market purchases. The Rule 10b5-1 plan was completed on June 30, 2017. Additional share repurchases, if any, will be made through open market purchases, Rule 10b5-1 plans, accelerated share repurchases, privately negotiated transactions or other transactions in such amounts and at such times as we deem appropriate based upon prevailing market and business conditions and other factors.

Note 8 - Stock-based compensation plans

Under the 2016 Long-Term Incentive Plan (the " 2016 LTIP "), we may issue stock options, stock appreciation rights ("SARs"), restricted stock awards, restricted stock units, performance share awards and other types of awards. The maximum number of shares available for awards under the 2016 LTIP is 33.0 million . The maximum term of stock options, SARs, restricted stock awards, restricted stock units and performance shares granted under the 2016 LTIP is 10 years.

Effective May 4, 2016, no additional awards may be granted under the 2011 Long-Term Incentive Plan (the "2011 LTIP"), the Accredo Health, Incorporated 2002 Long-Term Incentive Plan (the "Accredo Plan"), the ESI 2000 Long-Term Incentive Plan (the "2000 LTIP") or the Medco 2002 Stock Incentive Plan (the "2002 SIP") (except to settle awards outstanding under these plans), which authorized the grant of various equity awards with various terms to our officers, members of our Board of Directors and other key employees. However, the terms of these plans will continue to govern awards outstanding under these plans.

The provisions of the 2016 LTIP , the 2011 LTIP, the Accredo Plan, the 2000 LTIP and the 2002 SIP (collectively, the "stock incentive plans") allow employees to use shares to cover tax withholding on stock awards (a feature which has also been approved by the Compensation Committee of our Board of Directors). Upon vesting of restricted stock units and performance shares, employees have taxable income subject to statutory withholding requirements. The number of shares issued to employees may be reduced by the number of shares having a market value equal to our minimum statutory withholding for federal, state and local tax purposes.

Table of Contents

Under the stock incentive plans, we have issued stock options, restricted stock units and performance shares. All such awards are settled by issuance of new shares.

Awards granted under the stock incentive plans are subject to accelerated vesting under certain specified circumstances, including upon a change in control and termination, and are also subject to forfeiture without consideration upon termination of employment under certain circumstances. The maximum term of stock options is generally 10 years.

As of January 1, 2017, under ASU 2016-09, excess tax benefits, which are immaterial for the three and six months ended June 30, 2017 , are prospectively recognized as income tax expense on our consolidated statement of operations and prospectively recognized as an operating activity on our consolidated statement of cash flows for the six months ended June 30, 2017 . Prior periods have not been retrospectively adjusted for adoption of this standard. We have also elected to continue to estimate the number of awards that are expected to vest. The remaining amendments to this standard, as noted in Note 1 - Summary of significant accounting policies , are either not applicable or do not change our current accounting practices and thus do not impact our consolidated financial statements, including our consolidated statement of cash flows.

We recognized stock-based compensation expense of $25.0 million and $26.8 million in the three months ended June 30, 2017 and 2016 , respectively, and $52.1 million and $54.7 million in the six months ended June 30, 2017 and 2016 , respectively. Unamortized stock-based compensation as of June 30, 2017 was $27.5 million for stock options and $105.9 million for restricted stock units and performance shares.

Stock options. During the six months ended June 30, 2017 , we granted 0.8 million stock options with a weighted-average fair market value of $13.89 per share. Stock options granted generally have three -year graded vesting.

The fair value of stock options granted was estimated on the date of grant using a Black-Scholes multiple option-pricing model with the following weighted-average assumptions:



	Three Months Ended June 30,		Six Months Ended June 30,
	2017	2016	2017	2016
Expected life of option	3-5 years	3-5 years	3-5 years	3-5 years
Risk-free interest rate	1.5%-2.0%	0.9%-1.3%	1.5%-2.1%	0.9%-1.4%
Expected volatility of stock	21%-23%	20%-25%	21%-23%	20%-25%
Expected dividend yield	None	None	None	None

The Black-Scholes model requires subjective assumptions, including future stock price volatility and expected time to exercise, which affect the calculated values. The expected term and forfeiture rate of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior as well as expected behavior on outstanding options. The risk-free rate is based on the United States Treasury rates in effect during the corresponding period of grant. The expected volatility is based on the historical volatility of our stock price. These factors could change in the future, which would affect the stock-based compensation expense recognized in future periods.

Restricted stock units and performance shares. During the six months ended June 30, 2017 , we granted 1.7 million restricted stock units and performance shares with a weighted-average fair market value of $67.47 per share. Restricted stock units generally have three -year graded vesting. Performance shares generally have three -year cliff vesting. The number of performance shares that ultimately vest is dependent upon the achievement of specific performance metrics. The original grant of performance shares is subject to a multiplier of up to 2.5 based on the achievement of the performance metrics. Due to the achievement of certain performance metrics, during the six months ended June 30, 2017 , 0.1 million shares of common stock were issued in settlement of performance shares granted in March 2014.

Note 9 - Commitments and contingencies

We are subject to various legal proceedings, investigations, government inquiries and claims pending against us or our subsidiaries, including, but not limited to, those relating to regulatory, commercial, employment and employee benefits. We record accruals for certain of our outstanding legal proceedings, investigations and claims when we believe it is probable a liability will be incurred and the amount of loss can be reasonably estimated. On a quarterly basis, we evaluate developments in legal proceedings, investigations and claims that could affect the amount of any accrual, as well as any developments that would make a loss both probable and reasonably estimable.

We record self-insurance accruals based on estimates of the aggregate liability of claim costs (including defense costs) in excess of our insurance coverage. The majority of these claims are legal claims and our liability estimate is primarily related

Table of Contents

to the cost to defend these claims. We do not accrue for settlements, judgments, monetary fines or penalties until such amounts are probable and estimable. If the range of possible loss is broad, and no amount within the range is more likely than any other, the liability accrual is based on the low end of the range.

When a loss contingency is not believed to be both probable and estimable, we do not establish an accrued liability. However, if the loss (or an additional loss in excess of the accrual) is believed to be at least a reasonable possibility and material, then we disclose an estimate of the possible loss or range of loss, if such estimate can be made, or disclose an estimate cannot be made.

The legal proceedings, investigations, government inquiries and claims pending against us or our subsidiaries include multi-district litigation, class action lawsuits, antitrust allegations, qui tam lawsuits ("whistleblower" actions) and various governmental inquiries and informational subpoenas.

The assessment of whether a loss is probable and reasonably estimable involves a series of complex judgments about future events. We are often unable to estimate a range of loss due to significant uncertainties, particularly where (i) the damages sought are unspecified or indeterminate; (ii) the proceedings are in the early stages; (iii) the matters involve novel or unsettled legal theories or a large number of parties; (iv) class action status may be sought and certified; (v) it is questionable whether asserted claims or allegations will survive dispositive motion practice; (vi) the impact of discovery on the legal process is unknown; (vii) the settlement posture of the parties has not been determined and/or (viii) in the case of certain government agency investigations, whether a sealed qui tam lawsuit has been filed and whether the government agency makes a decision to intervene in the lawsuit following investigation. Accordingly, for many proceedings, we are currently unable to estimate the loss or a range of possible loss.

For a limited number of proceedings, we may be able to reasonably estimate the possible range of loss in excess of any accruals. However, we believe such proceedings, individually and in the aggregate, when finally resolved, are not reasonably likely to have a material adverse effect on our cash flow or financial condition. We also believe any amount that could be reasonably estimated in excess of accruals, if any, for such proceedings is not material. However, an unexpected adverse resolution of one or more of such proceedings could have a material adverse effect on our results of operations in a particular quarter or fiscal year.

We cannot predict the timing or outcome of the matters described below:

•

Jerry Beeman, et al. v. Caremark, et al. Plaintiffs allege that ESI and the other defendants failed to comply with statutory obligations to provide California clients with the results of a bi-annual survey of retail drug prices. On November 14, 2016, the district court denied plaintiffs' motion for class certification, holding that the proposed class representatives and counsel were inadequate to represent a class. Plaintiffs' request to substitute the proposed class representatives was denied on June 9, 2017.

•

Brady Enterprises, Inc., et al. v. Medco Health Solutions, Inc., and North Jackson Pharmacy, Inc., et al. v. Express Scripts, Inc., et al. Plaintiffs assert claims for violation of the Sherman Antitrust Act. The court has entered an order denying class certification in the Brady case and decertifying the class against ESI and Medco in the North Jackson case. The Brady plaintiffs have filed a motion requesting reconsideration of the court's denial of class certification.

•

Anthem, Inc. v. Express Scripts, Inc. Anthem, Inc. (for purposes of this Note 9, "Anthem") filed this lawsuit alleging various breach of contract claims against ESI relating to the parties' rights and obligations under the periodic pricing review section of the pharmacy benefit management agreement between the parties, including allegations that ESI failed to negotiate new pricing concessions in good faith, as well as various alleged service issues. Anthem requests the court enter declaratory judgment that ESI is required to provide Anthem competitive benchmark pricing, that Anthem can terminate the agreement, and that ESI is required to provide Anthem with post-termination services at competitive benchmark pricing for one year following any termination by Anthem. Anthem claims it is entitled to $13,000.0 million in additional pricing concessions over the remaining term of the agreement as well as $1,800.0 million for one year following any contract termination by Anthem, and $150.0 million in damages for service issues (for purposes of this Note 9, "Anthem's Allegations"). On April 19, 2016, in response to Anthem's complaint, ESI filed its answer denying Anthem's Allegations in their entirety and asserting affirmative defenses and counterclaims against Anthem. The court subsequently granted Anthem's motion to dismiss two of six counts of ESI's amended counterclaims.

In re Express Scripts Holdings Company Securities Litigation. Plaintiff filed this putative securities class action complaint on behalf of all persons or entities that purchased or otherwise acquired the Company's publicly traded common stock between February 24, 2015 and March 21, 2016 and alleges the Company and named individuals violated Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 by carrying out a scheme to defraud the

Abraham Neufeld, derivatively on behalf of nominal defendant Express Scripts Holding Company v. George Paz, et al. ; Robert Jessup, derivatively on behalf of Express Scripts Holding Company v. Timothy Wentworth, et al. ; and Richard Weisglas, derivatively on behalf of Express Scripts Holding Company v. Express Scripts Holding Company, George Paz, et al. These cases were consolidated on December 21, 2016, and on April 13, 2017 plaintiffs filed a consolidated amended complaint. Plaintiffs' consolidated amended complaint alleges certain current and former officers and directors of the Company breached fiduciary duties and were unjustly enriched, and that certain defendants engaged in "insider selling." Plaintiffs adopt many of Anthem's Allegations in support of their claims that the individual defendants breached fiduciary duties of loyalty, good faith, candor, and due care, which caused the Company to issue false and misleading statements regarding the Company's relationship with Anthem. Plaintiffs seek damages on behalf of the Company from the individual defendants, equitable relief, and attorneys' fees and costs.

•

M. Scott Brewer, et al., in their capacities as Trustees for the Carpenters Pension Fund of West Virginia, derivatively on behalf of Express Scripts Holding Company v. Maura C. Breen, et al. Plaintiffs filed this stockholder derivative lawsuit alleging certain current and former officers and directors of the Company breached fiduciary duties and were unjustly enriched and also asserting a claim for corporate waste. Plaintiffs adopt many of Anthem's Allegations in support of their claim. Plaintiffs seek damages on behalf of the Company from the individual defendants, an accounting by the individual defendants for all damages, profits, special benefits and unjust enrichment and imposition of a constructive trust, judgment directing the Company to take all necessary actions to reform and improve its corporate governance and internal control procedures, punitive damages, and an award of attorneys' fees and costs.

Plaintiffs allege that the Company and Anthem breached fiduciary duties and otherwise violated their legal obligations under ERISA, that ESI engaged in mail fraud, wire fraud and other racketeering activity through its invoicing system with Anthem, that ESI breached its contract with Anthem, that plaintiffs are entitled to equitable relief under theories including unjust enrichment, that ESI violated unfair and deceptive trade practices statutes, that Anthem breached the covenant of good faith and fair dealing implied in health plans, and that ESI violated the anti-discrimination provisions of the Affordable Care Act. Plaintiffs adopt many of Anthem's Allegations in support of their claim. Plaintiffs seek compensatory damages, declaratory relief, equitable relief and attorneys' fees and costs. On June 9, 2017, plaintiffs filed a brief in opposition to the motion to dismiss and ESI filed its reply brief on July 21, 2017.

The complaint alleges that these agreements had the effect of driving up analog insulin costs for the putative class members and violated Sections 1 and 3 of the Sherman Act, the Racketeer Influenced and Corrupt Organizations Act (RICO) and the competition and consumer protection laws of various states, U.S. territories, and the District of Columbia. Plaintiffs seek treble damages, equitable relief and attorneys' fees and costs.

•

Elan and Adam Klein, et al. v. Prime Therapeutics, LLC; Express Scripts Holding Co.; Express Scripts, Inc.; and CVS Health Corp. Plaintiffs allege that defendants violated legal obligations under ERISA by negotiating increasingly large rebates from Mylan, which allegedly caused an increase in the price of EpiPen products. Plaintiffs further allege that defendants retained a significant portion of rebates, rather than passing them on to class members (who are participants in, or beneficiaries of, health insurance plans governed by ERISA who purchased EpiPen products).

•

City of Rockford v. Mallinckrodt ARD Inc., f/k/a Questcor Pharmaceuticals, Inc., Mallinckrodt plc, and United Biosource Corporation . A complaint was filed against United Biosource Corporation (for purposes of this Note 9, "UBC", a subsidiary of the Company) and Mallinckrodt ARD Inc. (for purposes of this Note 9, "Mallinckrodt"), the manufacturer of Acthar, which is an adrenocorticotropic hormone (for purposes of this Note 9, "ACTH"). The City of Rockford, Illinois alleges, inter alia , that Mallinckrodt had a monopoly in ACTH, protected that monopoly by acquiring its only potential competitor, and used its monopoly power to raise the price of Acthar, and that UBC aided in this scheme by acting as Mallinckrodt's exclusive agent and distributor for Acthar. Plaintiff alleges that this scheme violated Sections 1 and 2 of the Sherman Act, RICO and Illinois' Consumer Fraud and Deceptive Practices Act. Plaintiff seeks treble damages, equitable relief and attorneys' fees and costs.


•	We are the subject of various qui tam matters:

•

United States ex. rel. Steve Greenfield, et al. v. Medco Health Solutions, Inc., Accredo Health Group, Inc., and Hemophilia Health Services, Inc. The complaint alleges defendants violated the federal False Claims Act, the Anti-Kickback Statute, the Civil Monetary Penalty Statute and various state and local false claims statutes. The court granted the Company's motion for summary judgment and Greenfield has appealed the decision.


•	United States of America ex. rel. Shane Lager v. CSL Behring, LLC, CSL Limited, Accredo Health, Inc., and Coram LLC. The complaint alleges Accredo violated the federal False Claims Act. The court granted the Company's motion to dismiss and Lager has appealed the decision.


•	We have received and intend to cooperate with various subpoenas from government agencies requesting information.

While we believe our services and business practices are in substantial compliance with applicable laws, rules and regulations in all material respects, we cannot predict the outcome of these actions at this time. An unfavorable outcome in one or more of these matters could result in the imposition of judgments, monetary fines or penalties or injunctive or administrative remedies. It is not possible to predict with certainty the outcome of these claims, and we can give no assurance that any losses in excess of our insurance and any self-insurance accruals will not be materially adverse to our financial results.

Note 10 - Segment information

We report segments on the basis of products and services offered and have determined we have two reportable segments: PBM and Other Business Operations. Within the Other Business Operations segment, we have aggregated two operating segments that do not meet the quantitative and qualitative criteria to be separately reported.

Operating income is the measure used by our chief operating decision maker to assess the performance of each of our operating segments. Following is information about our reportable segments, including a reconciliation of operating income to income before income taxes for the three and six months ended June 30, 2017 and 2016 .

Note 11 - Condensed consolidating financial information

The senior notes issued by us, ESI and Medco are jointly and severally and fully and unconditionally (subject to certain customary release provisions, including sale, exchange, transfer or liquidation of the guarantor subsidiary) guaranteed by certain of our 100% owned domestic subsidiaries, other than certain regulated subsidiaries, and, with respect to notes issued by ESI and Medco, by Express Scripts Holding Company. The following condensed consolidating financial information has been prepared in accordance with the requirements for presentation of such information. The condensed consolidating financial information presented below is not indicative of what the financial position, results of operations or cash flows would have been had each of the entities operated as an independent company during the period for various reasons, including, but not limited to, intercompany transactions and integration of systems.

The following presentation reflects the structure that exists as of the most recent balance sheet date. The condensed consolidating financial information is presented separately for:


(i)	Express Scripts Holding Company (the Parent Company), the issuer of certain guaranteed obligations;


(ii)	ESI, guarantor, the issuer of additional guaranteed obligations;


(iii)	Medco, guarantor, the issuer of additional guaranteed obligations;


(iv)	Guarantor subsidiaries, on a combined basis (but excluding ESI and Medco), as specified in the indentures related to Express Scripts Holding Company's, ESI's and Medco's obligations under the notes;


(v)	Non-guarantor subsidiaries, on a combined basis;


(vi)	Consolidating entries and eliminations representing adjustments to (a) eliminate intercompany transactions between or among Express Scripts Holding Company, ESI, Medco, the guarantor subsidiaries and the non-guarantor subsidiaries, (b) eliminate the investments in our subsidiaries and (c) record consolidating entries; and


(vii)	Express Scripts Holding Company and its subsidiaries on a consolidated basis.

In 2017, as part of an ongoing reorganization since 2015, certain subsidiaries have been merged within the structure defined above through non-cash transfers. The 2017 reorganizations qualified as a transfer of assets and are reflected prospectively in the condensed consolidating balance sheet, statement of operations and statement of cash flows. These events had no impact on our consolidated balance sheet, consolidated statement of operations or consolidated statement of cash flows.

In conjunction with the ongoing reorganization, during both the first and second quarters of 2017, we executed certain intercompany agreements and transfer pricing agreements effective retrospectively to January 1, 2017. These intercompany agreements resulted in increased SG&A for our subsidiaries and reduced SG&A for ESI in the condensed consolidating statement of operations for the three and six months ended June 30, 2017 . The transfer pricing agreements resulted in increased revenues and costs of revenues for ESI, Medco and our subsidiaries with a resulting increase in the eliminations column. These events had no impact on our consolidated balance sheet, consolidated statement of operations or consolidated statement of cash flows.

OVERVIEW

As the largest stand-alone pharmacy benefit management ("PBM") company in the United States, we provide a full range of services to our clients, which include managed care organizations, health insurers, third-party administrators, employers, union-sponsored benefit plans, workers' compensation plans, government health programs, providers, clinics, hospitals and others. We report segments on the basis of products and services offered and have determined we have two reportable segments: PBM and Other Business Operations. Our integrated PBM services include clinical solutions, Express Scripts SafeGuardRx, specialized pharmacy care, home delivery pharmacy services, specialty pharmacy services, retail network pharmacy administration, benefit design consultation, drug utilization review, drug formulary management, Medicare, Medicaid and Public Exchange offerings, administration of a group purchasing organization and consumer health and drug information.

Through our Other Business Operations segment, we provide distribution services of specialty pharmaceuticals and medical supplies to providers, clients and hospitals and provide consulting services for pharmaceutical and biotechnology manufacturers to collect scientific evidence to guide the safe, effective and affordable use of medicines.

Revenues generated by our segments can be classified as either tangible product revenues or service revenues. We earn tangible product revenues from the sale of prescription drugs by retail pharmacies in our retail pharmacy networks and from dispensing prescription drugs from our home delivery and specialty pharmacies. Service revenues include administrative fees associated with the administration of retail pharmacy networks contracted by certain clients, informed decision counseling services and certain specialty pharmacy services. Tangible product revenues generated by our PBM and Other Business Operations segments represented 98.2% and 98.4% of revenues for the three months ended June 30, 2017 and 2016 , respectively, and 98.3% of revenues for both the six months ended June 30, 2017 and 2016 .

Our PBM revenues are primarily comprised of:

(1) total prescription price, which includes a negotiated price with the client and a fee related to dispensing at retail pharmacies;

(2) member co-payments;

(3) administrative and service fees; and

(4) offsets to revenues that we consider client discounts, which include manufacturer rebates payable to clients, obligations under financial and service guarantees to clients, and pricing discounts.

Cost of revenues of our PBM business are primarily comprised of:

(1) ingredient cost;

(2) a dispensing fee at retail;

(3) direct costs associated with dispensing prescriptions, including direct processing labor and shipping and handling costs;

(4) member co-payments to retail pharmacies; and

(5) purchase discounts, which are an offset to cost of revenues and include volume discounts and rebates received from manufacturers.

We believe the key drivers that impact PBM revenues and cost of revenues are claims volume, claims mix and price.


•	As our claims volume increases or decreases, our associated revenues and cost of revenues correspondingly increase or decrease. Our gross profit also could increase or decrease as a result of changes in purchasing discounts.

•

The mix of claims generally includes the type of drug adjudicated and the distribution method in which a claim is dispensed. As our mix of drugs changes, our associated revenues and cost of revenues correspondingly may increase or decrease. The primary driver of fluctuations within our mix of claims is the generic fill rate. Generally, higher generic fill rates reduce PBM revenues, as generic drugs are typically priced lower than the branded drugs they replace. However, as ingredient cost paid to pharmacies on generic drugs is incrementally lower than the price charged to our clients, higher generic fill rates generally have a favorable impact on our gross profit. The home delivery generic fill rate is currently lower than the network generic fill rate as fewer generic substitutions are available among maintenance medications (e.g. therapies for chronic conditions) commonly dispensed from home delivery pharmacies as compared to acute medications, which are primarily dispensed by pharmacies in our retail networks.

•

Our PBM contract pricing is impacted by our ability to negotiate pharmacy network contracts, pharmaceutical and wholesaler purchasing contracts, and manufacturer rebate contracts. Through our integrated set of solutions, we are able to reduce the rate of increase of our clients' prescription drug spend, and, in some cases, lower our clients' prescription drug costs, which may ultimately reduce our revenues while positively affecting our gross profit. We refer to the management of these solutions as "management of supply chain". Inflation also impacts our pricing. Most of our contracts provide that we bill clients and pay pharmacies based on a generally recognized price index for pharmaceuticals and accordingly, the rate of inflation with respect to prescription drugs and our efforts to manage the impact of inflation for our clients can affect our revenues and cost of revenues.

EXECUTIVE SUMMARY AND TREND FACTORS AFFECTING THE BUSINESS

We operate in a dynamic environment influenced by a number of marketplace forces including healthcare legislation, increased regulation, macroeconomic factors and competition. We recognize continued consolidation within the broad healthcare sector could shift claims volume within the PBM industry, although the direction and degree of any impact remain unclear. Our claims volume has been impacted by certain in-group attrition and client losses. We also recognize that as the regulatory environment evolves, it may be necessary to make significant investments in order to prepare for and adapt to regulatory changes. We continue to execute our successful business model, which emphasizes the alignment of our financial interests with those of our clients and patients through greater use of generics and lower-cost brands delivered through home delivery, specialty and retail pharmacies as well as the adoption of new cost saving product programs and solutions. We also continue to benefit from better management of ingredient costs through renegotiation of supplier contracts, increased competition among generic manufacturers and a higher generic fill rate ( 86.6% and 86.5% for the three and six months ended June 30, 2017 , respectively, as compared to 85.6% and 85.4% for the three and six months ended June 30, 2016 , respectively). We have achieved higher generic fill rates as we continue to provide our clients with additional tools designed to proactively manage total drug spend by increasing lower cost alternatives. We expect these ongoing positive trends in our business will continue to offset the negative factors described above.

Anthem Relationship

Our contract with Anthem, Inc. ("Anthem") expires at the end of 2019 with a one year transition period through 2020. Based on recent statements made and other actions taken by Anthem management, the Company believes it is unlikely its contract with Anthem will be extended. If we do enter into a new contract with Anthem, it would be on terms significantly less favorable to us than our current contract. Anthem's decision whether to enter into a new contract with us, the terms of any new contract and the impact of non-renewal or new contract terms on our business will depend on a number of factors that we cannot currently anticipate or control, and could result in a material adverse effect on our business, cash flows and results of operations. We continue to focus on providing exceptional service to Anthem and its clients in accordance with the terms of our contract.

Our Anthem contract generated approximately 19% of our total consolidated revenues and 33% of our total EBITDA attributable to Express Scripts ("EBITDA") for both the three and six months ended June 30, 2017 , respectively. Under the terms of our contract with Anthem, Anthem's contribution to our profitability, as a percentage of our total EBITDA, has grown and we expect it will continue to increase and exceed its contribution to our revenues, as a percentage of our total revenues, and that revenues and EBITDA attributable to Anthem will increase as the contract nears its termination in 2019.

In addition, on March 21, 2016, Anthem filed a lawsuit setting forth certain allegations and claims for relief with respect to our pharmacy benefit management agreement with Anthem (see Part II - Item 1 - "Legal Proceedings"). We are confident in the strength of our legal position and believe that we have consistently acted in good faith and in accordance with the terms of the agreement and have a number of valid defenses to the claims asserted. We further believe Anthem's lawsuit is without merit. However, litigation and the potential outcome cannot be accurately or effectively predicted and at this time we are unable to provide a timetable or an estimate as to the potential outcome of this matter, which could result in a material adverse effect on our business and results of operations.

When we executed our agreement with Anthem in 2009, we considered the overall structure of the agreement and the nature of our relationship with Anthem, including the complexity of the service level required, and attributed a reasonable likelihood of renewal at the end of its term in 2019. Accordingly, we amortized the agreement using a modified pattern of benefit over an estimated useful life of 15 years. However, due to the sequence of events regarding our discussions with Anthem, culminating in the filing of the lawsuit on March 21, 2016, we felt it prudent to consider the increased likelihood of either non-renewal or renewal on substantially different terms such that, beginning in March 2016, we began amortizing our agreement with Anthem over the remaining term of the contract (i.e., using a life of 10 years from the time the agreement was executed in 2009). Previously, we amortized the agreement over 15 years. Therefore, the intangible asset amortization associated with the Anthem agreement will run through the remaining term of the contract at the end of 2019, reducing the

previous amortization period by 5 years. This change increases the quarterly intangible asset amortization by approximately $32.0 million and has no impact on EBITDA.

As part of the Anthem contract, certain additional revenues related to Anthem were realized in the second quarters of each of 2017, 2016, 2015 and 2014 due to the structure of the contract. Quarterly performance trends may vary from historical periods as a result of variability, including timing, of our Anthem-related contractual revenue streams.

RESULTS OF OPERATIONS

We report segments on the basis of the products and services we offer and have determined we have two reportable segments: PBM and Other Business Operations. Our PBM segment includes our integrated PBM operations and specialty pharmacy operations. Our Other Business Operations segment includes United BioSource ("UBC") and our specialty distribution operations.

As reported in our Annual Report on Form 10-K filed with the SEC on February 14, 2017 , to better reflect utilization patterns that have developed over time as we align our products and services to deliver greater value through both the network and home delivery channels, the Company has revised its methodology for reporting adjusted network claims for the year ended December 31, 2016. The change was made retrospectively for the three and six months ended June 30, 2016 . The revised methodology includes an adjustment to reflect non-specialty network claims filled through our 90-day programs. These claims are now multiplied by three, as these claims, on average, typically cover a time period three times longer than other network claims. Home delivery claims are also multiplied by three, consistent with prior practice, as home delivery claims typically cover a time period three times longer than unadjusted network claims. All other network and specialty claims are counted as one claim.

This increase was primarily due to increased interest expense related to the issuance of $4,000.0 million of senior notes in July 2016. This increase was partially offset by decreased interest expense related to the repayment of various debt during the year ended December 31, 2016 and the six months ended June 30, 2017 .

Net other expense increased $20.8 million , or 8% , in the six months ended June 30, 2017 from 2016 . This increase was primarily due to increased interest expense related to the issuance of $2,000.0 million of senior notes in February 2016 and the issuance of $4,000.0 million of senior notes in July 2016. This increase was partially offset by $6.7 million of costs related to the early repayment of debt during the six months ended June 30, 2016 compared to no such costs for the six months ended June 30, 2017 , as well as decreased interest expense related to the repayment of various debt during the year ended December 31, 2016 and the six months ended June 30, 2017 .

PROVISION FOR INCOME TAXES

Our effective tax rate attributable to Express Scripts decreased to 35.2% and increased to 37.3% for the three and six months ended June 30, 2017 , respectively, from 35.8% and 35.3% for the same periods in 2016 due to discrete events. We believe it is reasonably possible our unrecognized tax benefits could decrease by approximately $70.6 million within the next twelve months due to the conclusion of various examinations as well as lapses in various statutes of limitations.

NET INCOME ATTRIBUTABLE TO NON-CONTROLLING INTEREST

Net income attributable to non-controlling interest represents the share of net income allocated to members in our consolidated affiliates. These amounts are directly impacted by the profitability of our consolidated affiliates.

NET INCOME AND EARNINGS PER SHARE ATTRIBUTABLE TO EXPRESS SCRIPTS

Net income attributable to Express Scripts for the three and six months ended June 30, 2017 increase d $81.1 million , or 11% , and $101.3 million , or 8% , respectively, from 2016 due to the factors described above.

Basic and diluted earnings per share attributable to Express Scripts both increase d 21% for the three months ended June 30, 2017 from 2016 , and increase d 17% and 16% , respectively, for the six months ended June 30, 2017 from 2016 . These increase s are primarily due to reduced shares outstanding (a total of 283.8 million shares held in treasury on June 30, 2017 , compared to 226.2 million shares held in treasury on June 30, 2016 ), as well as higher operating income.

EBITDA ATTRIBUTABLE TO EXPRESS SCRIPTS

Provided below is a reconciliation of EBITDA to net income attributable to Express Scripts, as we believe it is the most directly comparable measure calculated under U.S. generally accepted accounting principles ("GAAP"):



EBITDA (1)	Three Months Ended June 30,				Six Months Ended June 30,
(in millions, except per claim data)	2017		2016		2017		2016
Net income attributable to Express Scripts	$	801.8	$	720.7	$	1,348.1	$	1,246.8
Provision for income taxes	435.4		402.7		800.3		681.5
Depreciation and amortization (2)	449.2		548.2		894.8		1,073.5
Interest expense, interest income and other	137.7		126.5		277.1		256.3
EBITDA (1)	1,824.1		1,798.1		3,320.3		3,258.1
Total adjusted claims (3)	350.0		349.3		701.7		705.6
EBITDA per adjusted claim (4)	$	5.21	$	5.15	$	4.73	$	4.62

(1)

EBITDA is presented as attributable to Express Scripts, excluding non-controlling interest representing the share allocated to members of our consolidated affiliates. EBITDA is a financial measure that is not calculated or presented in accordance with GAAP and should be considered in addition to, but not as a substitute for, or superior to, financial measures prepared in accordance with GAAP. The Company believes that EBITDA provides management and investors with useful information about the earnings impact of certain expenses and are useful for (i) comparison of our earnings to those of other companies; (ii) a better understanding of the Company's ongoing core performance; (iii) planning and forecasting for future periods; and (iv) assessing period-to-period performance trends. Management assesses the Company's operating performance using EBITDA in order to better isolate the impact of certain expenses that may not be comparable between periods or indicative of the ongoing performance of our core operations.

(2)

Depreciation and amortization includes an additional $31.7 million for both the three months ended June 30, 2017 and 2016 and $63.4 million and $42.2 million for the six months ended June 30, 2017 and 2016 , respectively, related to our decision to amortize our pharmacy benefit management agreement with Anthem over 10 years as opposed to 15 years. See Note 3 - Goodwill and other intangible assets for additional details.

(3)

Includes an adjustment to reflect non-specialty network claims filled through our 90-day programs. These claims are multiplied by three, as these claims, on average, typically cover a time period three times longer than other network claims. Home delivery claims are also multiplied by three as home delivery claims typically cover a time period three times longer than unadjusted network claims. All other network and specialty claims are counted as one claim.

(4)

EBITDA per adjusted claim is calculated by dividing EBITDA by the adjusted claim volume for the period. EBITDA per adjusted claim is a financial measure that is not calculated or presented in accordance with GAAP, and should be considered in addition to, but not as a substitute for, or superior to, financial measures prepared in accordance with GAAP. The Company believes that EBITDA per adjusted claim provides management and investors with useful information about the earnings and performance of the Company on a per unit basis.

LIQUIDITY AND CAPITAL RESOURCES

CASH FLOW AND CAPITAL EXPENDITURES

In the six months ended June 30, 2017 , net cash provided by operating activities increased $891.5 million to $2,081.6 million , due partially to an increase in net income of $96.5 million in 2017 from 2016 . In addition, changes in working capital resulted in a cash outflow of $65.9 million in 2017 compared to a cash outflow of $980.6 million in 2016 , resulting in a total change to net cash provided by operating activities of $914.7 million .

In the six months ended June 30, 2017 , net cash used in investing activities increased $73.6 million to $235.5 million , due primarily to cash utilized for an acquisition in 2017 of $122.7 million compared to no such outflows during the same period of 2016 the impact of which was offset by a decrease in capital expenditures for purchases of property and equipment of $53.2 million in 2017 from 2016 . We intend to continue to invest in infrastructure and technology we believe will provide efficiencies in operations, facilitate growth and enhance the services we provide to our clients. Anticipated capital expenditures are expected to be funded primarily from operating cash flow or, to the extent necessary, with borrowings under our available credit sources described below.

In the six months ended June 30, 2017 , net cash used in financing activities decreased $320.2 million to $2,573.8 million . Cash outflows for 2017 include $2,020.0 million of treasury share repurchases and $575.0 million related to the repayment of debt, compared to outflows during the same period of 2016 of $3,320.2 million of treasury share repurchases and $1,575.0 million related to the repayment of debt. Cash inflows for 2016 include $1,991.0 million related to the issuance of senior notes in February 2016 compared to no such inflows during the same period of 2017 .

We anticipate our current cash balances, cash flows from operations and our available credit sources will be sufficient to meet our cash needs and make scheduled payments for our contractual obligations and current capital commitments. However, if needs arise, we may decide to secure external capital to provide additional liquidity. New sources of liquidity may include additional lines of credit, term loans, or issuance of notes or equity, all of which are allowable, with certain limitations, under our credit agreements and other debt instruments. While our ability to secure debt financing in the short term at rates favorable to us may be moderated due to various factors, including existing debt levels, market conditions or other factors, we believe our liquidity options described above are sufficient to meet our anticipated cash flow needs.

ACQUISITIONS AND RELATED TRANSACTIONS

In May 2017, we completed the acquisition of myMatrixx Holdings, Inc. for approximately $250.0 million. The acquisition is not material to our consolidated financial statements. We regularly review potential acquisitions and affiliation opportunities. We believe available cash resources, bank financing or the issuance of debt or equity could be used to finance future acquisitions or affiliations. There can be no assurance we will enter into new acquisitions or establish new affiliations in the future.

BANK CREDIT FACILITIES

In April 2015, we entered into a credit agreement (the " 2015 credit agreement ") providing for a five -year $2,000.0 million revolving credit facility (the " 2015 revolving facility ") and a five -year $3,000.0 million term loan (the " 2015 five-year term loan "). At June 30, 2017 , no amounts were outstanding under the 2015 revolving facility . We make quarterly principal payments on the 2015 five-year term loan . See Note 5 - Financing for additional details.

We have two additional credit agreements, each providing for an uncommitted revolving credit facility: $150.0 million executed August 2015 and amended most recently in May 2017, with a termination date of May 2018, and $130.0 million executed May 2017 with a termination date of May 2018. At June 30, 2017 , no amounts were drawn under either facility. In April 2017, we terminated a separate $130.0 million uncommitted revolving credit facility executed December 2014 and amended October 2015 and April 2016.

Our bank financing arrangements and senior notes contain certain customary covenants that restrict our ability to incur additional indebtedness, create or permit liens on assets and engage in mergers or consolidations. The covenants related to bank financing arrangements also include, among other things, a maximum leverage ratio. The 7.125% senior notes due March 2018 issued by Medco are also subject to an interest rate adjustment in the event of a downgrade in our credit ratings to below investment grade. At June 30, 2017 , we were in compliance with all covenants associated with our debt instruments.

IMPACT OF INFLATION

Most of our contracts provide that we bill clients and pay pharmacies based on a generally recognized price index for pharmaceuticals and accordingly, the rate of inflation with respect to prescription drugs and our efforts to manage the impact of inflation for our clients can affect our revenues and cost of revenues.

OTHER MATTERS

In August 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The guidance addresses the classification of cash flow related to (1) debt prepayment or extinguishment costs, (2) settlement of zero-coupon debt instruments or other debt instruments with coupon rates that are insignificant in relation to the effective interest rate of the borrowing, (3) contingent consideration payments made after a business combination, (4) proceeds from the settlement of insurance claims, (5) proceeds from the settlement of corporate-owned life insurance, including bank-owned life insurance, (6) distributions received from equity method investees and (7) beneficial interests in securitization transactions. The guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The guidance will generally be applied retrospectively and is effective for financial statements issued for annual reporting periods beginning after December 15, 2017. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash. This guidance requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance will be applied retrospectively and is effective for financial statements issued for annual reporting periods beginning after December 15, 2017. We are currently evaluating the impact of these standards on our consolidated statement of cash flows.

CLIENTS

We are a provider of services to managed care organizations, health insurers, third-party administrators, employers, union-sponsored benefit plans, workers' compensation plans, government health programs, providers, clinics, hospitals and others. Refer to Note 10 - Segment information and Executive Summary and Trend Factors Affecting the Business for a description of client concentration.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Our estimates and assumptions are based upon a combination of historical information and various other assumptions believed to be reasonable under the particular circumstances. Actual results may differ from our estimates. For a description of our critical accounting policies, please refer to "Management's Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies" included in our Annual Report on Form 10-K filed with the SEC on February 14, 2017 .


Item 3.	Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk from changes in interest rates related to variable rate debt outstanding under the 2015 credit agreement . Our earnings are subject to change as a result of movements in market interest rates. At June 30, 2017 , we had $2,700.0 million of gross obligations under our 2015 credit agreement which were subject to variable rates of interest. A hypothetical increase in interest rates of 1% would result in an increase in annual interest expense of approximately $27.0 million (pre-tax), assuming obligations subject to variable interest rates remained constant.


Item 4.	Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 ("Exchange Act")) designed to provide reasonable assurance that information required to be disclosed in our filings under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based upon this evaluation, the Chief Executive Officer and the Chief Financial Officer concluded the design and operation of these disclosure controls and procedures are effective in providing reasonable assurance of the achievement of the objectives described above.

During the quarter ended June 30, 2017 , there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION


Item 1.	Legal Proceedings

We and/or our subsidiaries are defendants in a number of lawsuits. We cannot ascertain with any certainty at this time the monetary damages or injunctive relief that any of the plaintiffs may recover. We also cannot provide any assurance the outcome of any of these matters, or some number of them in the aggregate, will not be materially adverse to our financial condition, results of operations, cash flows or business prospects. In addition, the expenses of defending these cases may have a material adverse effect on our financial results.

The following descriptions have been updated since the filing of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2017, relating to proceedings involving the Company:

•

Jerry Beeman, et al. v. Caremark, et al. (United States District Court for the Central District of California, Case No.021327) (filed December 2002). A complaint was filed against Express Scripts, Inc. (for the purposes of this Item 1, "ESI"), NextRX LLC f/k/a Anthem Prescription Management LLC, Medco Health Solutions, Inc. (for purposes of this Item 1, "Medco") and several other pharmacy benefit management companies by several California pharmacies as a putative class action, alleging rights to sue as a private attorney general under California law. Plaintiffs allege ESI and the other defendants failed to comply with statutory obligations under California Civil Code Section 2527 to provide California clients with the results of a bi-annual survey of retail drug prices, and seek money damages. In July 2004, the case was dismissed with prejudice due to lack of standing. In June 2006, the United States Court of Appeals for the Ninth Circuit reversed the district court's opinion on standing and remanded the case. The defendants then filed a motion to dismiss on first amendment constitutionality grounds and following the district court's denial of the motion, defendants appealed to the Ninth Circuit. In March 2014, following a determination by the California Supreme Court that California Civil Code Section 2527 does not infringe upon state constitutional free speech protections, the Ninth Circuit remanded the case to the district court for further proceedings. Defendants' objections based on plaintiffs' lack of standing and the unconstitutionality of the California law due to defendants' first amendment rights were rejected by the courts and appeals were exhausted. Plaintiffs also filed a motion for class certification in 2007 that was not fully briefed until August 2016. On August 26, 2016, defendants filed a motion to deny class certification. On November 14, 2016, the district court denied plaintiffs' motion for class certification, holding that the proposed class representatives and counsel were inadequate to represent a class. Plaintiffs' request to substitute the proposed class representatives was denied on June 9, 2017.

Anthem-related ERISA Litigation

•

In re Express Scripts/Anthem ERISA Litigation (United States District Court for the Southern District of New York) (consolidated the following cases on August 1, 2016: John Doe One and John Doe Two v. Express Scripts, Inc. , filed May 6, 2016, and Karen Burnett, Brendan Farrell, and Robert Shullich v. Express Scripts, Inc. and Anthem, Inc. , filed June 24, 2016). On September 30, 2016, Plaintiffs filed a First Amended Consolidated Class Action Complaint on behalf of health plan beneficiaries who are enrolled in health care plans that are insured or administered by Anthem. Plaintiffs filed a Second Amended Consolidated Complaint on March 2, 2017, which adopts many of Anthem's Allegations (as defined in Part I - Item 1 - "Note 9 - Commitments and contingencies" of this Quarterly Report on Form 10-Q) in support of claims that the Company and Anthem breached fiduciary duties and otherwise violated their legal obligations under ERISA by failing to provide Anthem's plan participants the benefit of competitive benchmark pricing, that ESI engaged in mail fraud, wire fraud and other racketeering activity, that ESI breached its contract with Anthem, that plaintiffs are entitled to equitable relief under theories including unjust enrichment, that ESI violated unfair and deceptive trade practices statutes, that Anthem breached the covenant of good faith and fair dealing implied in health plans, and that ESI violated the anti-discrimination provisions of the Affordable Care Act. Plaintiffs seek compensatory damages, declaratory relief, equitable relief and attorneys' fees and costs. ESI filed a motion to dismiss the Second Amended Complaint on April 24, 2017. On June 9, 2017, plaintiffs filed a brief in opposition to the motion to dismiss and ESI filed its reply brief on July 21, 2017.

Anthem-related Shareholder Derivative Litigation

Plaintiffs filed this stockholder derivative lawsuit alleging certain current and former officers and directors of the Company breached fiduciary duties and were unjustly enriched. Plaintiffs adopt many of Anthem's Allegations in support of their claims that individual defendants breached fiduciary duties of loyalty, good faith, fair dealing, and candor, which caused the Company to issue false and misleading statements regarding the Company's relationship with Anthem and unjustly enriched individual defendants. Plaintiffs also assert a claim for corporate waste alleging the Company paid improper compensation, bonuses and other benefits to executives who breached their fiduciary duties to stockholders. Plaintiffs seek damages on behalf of the Company from the individual defendants, an accounting by the individual defendants for all damages, profits, special benefits and unjust enrichment, imposition of a constructive trust, judgment directing the Company to take all necessary actions to reform and improve its corporate governance and internal control procedures, punitive damages, and an award of attorneys' fees and costs. On June 29, 2017, defendants filed a motion to stay this action until resolution of the Anthem litigation and the Anthem-related shareholder derivative litigation in the United States District Court for the Southern District of New York (as described in Part I - Item 1 - "Note 9 - Commitments and contingencies" of this Quarterly Report on Form 10-Q) and, alternatively, a motion to dismiss this action for failure to plead demand futility and failure to state a claim.

On June 12, 2017, the court stayed this action until resolution of the Anthem-related shareholder derivative litigation in the United States District Court for the Southern District of New York.

Other Matters

•

United States ex. rel. Steve Greenfield, et al. v. Medco Health Solutions, Inc., Accredo Health Group, Inc., and Hemophilia Health Services, Inc. (United States District Court for the District of New Jersey) (unsealed February 2013). This qui tam case was filed under seal in January 2012 and the government declined to intervene. The complaint alleges that defendants, including Medco and Accredo Health Group, Inc. ("Accredo") violated the federal False Claims Act, the Anti-Kickback Statute, and various state and local false claims statutes by making charitable contributions to non-profit organizations supporting hemophilia patients that were allegedly improper rewards or inducements for referrals of hemophilia patients to Accredo's pharmacy services. The complaint further alleges that Accredo gave gifts to patients and/or their families that were in excess of the "nominal" gifts allegedly allowed under the Civil Monetary Penalty Statute and were allegedly improper rewards or inducements for the use of Accredo's pharmacy services. The complaint seeks monetary damages and civil monetary penalties on behalf of the federal

Table of Contents

government, as well as costs and expenses. In December 2013, the court granted defendants' motion to dismiss relating to Greenfield's federal claims and declined to exercise jurisdiction over his state law claims. In January 2014, Greenfield filed an amended complaint in which he asserts claims similar to those previously pled, but alleges that Accredo gave gifts to patients and/or their families in violation of the federal Anti-Kickback Statute as opposed to the Civil Monetary Penalty Statute. In September 2014, the court granted in part, and denied in part, defendants' motion to dismiss. Greenfield filed a further amended complaint in October 2014, and the Company filed an answer and affirmative defenses in November 2014. On May 6, 2016, the parties cross-filed motions for summary judgment and on December 22, 2016, the district court entered an order granting the Company's motion for summary judgment and denying plaintiff's motion for summary judgment. Greenfield filed a notice of appeal on January 17, 2017 and an appellate brief on April 10, 2017. On April 17, 2017, the United States filed an amicus curiae brief, which was not filed in support of either party. On June 9, 2017, the Company filed its appellate brief,

•

Elan and Adam Klein, Leah Weaver, and Arissa Paschalidis v. Prime Therapeutics, LLC; Express Scripts Holding Co.; Express Scripts, Inc.; and CVS Health Corp. (United States District Court for the District of Minnesota) (filed June 2, 2017). A complaint was filed against the Company, Prime Therapeutics and CVS Health Corp. by a putative class comprising participants in, or beneficiaries of, health insurance plans governed by ERISA who, pursuant to the terms of their health insurance plans, paid any portion of the purchase price for EpiPen products. The complaint alleges that defendants violated legal obligations under ERISA by negotiating increasingly large rebates from Mylan, which allegedly caused an increase in the price of EpiPen products. Plaintiffs further allege that defendants retained a significant portion of rebates, rather than passing them on to putative class members. Plaintiffs seek equitable relief and attorneys' fees and costs.

Investigations under the federal False Claims Act and most state false claims acts may be initiated by the applicable government investigative body or by a qui tam relator's filing of a complaint under court seal. If a qui tam relator's complaint remained under seal, applicable law would restrict our ability to disclose such a fact.

In addition to the foregoing matters there have arisen various legal proceedings, investigations or claims in the ordinary course of our business now pending against us or our subsidiaries. The effect of these actions on future financial results is not subject to reasonable estimation because the proceedings are in early stages and/or considerable uncertainty exists about the outcomes. Where insurance coverage is not available for such claims, or in our judgment, is not cost-effective, we maintain self-insurance accruals to reduce our exposure to future legal costs, settlements and judgments related to uninsured claims. Our self-insured accruals are based upon estimates of the aggregate liability for the costs of uninsured claims incurred and the retained portion of insured claims using certain actuarial assumptions followed in the insurance industry and our experience. It is not possible to predict with certainty the outcome of these claims, and we can give no assurance that any losses in excess of our insurance and any self-insurance accruals will not be material.


Item 1A.	Risk Factors

We have included below a revision to one of the risk factors included in Item 1A - "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2016. You should consider this risk factor together with other matters described under the caption "Forward Looking Statements and Associated Risks" contained in Item 1 - "Business" and Item 1A - "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2016 , filed with the SEC on February 14, 2017 .

A substantial portion of our business is concentrated in certain significant client contracts. The termination or renegotiation of a significant client contract or our failure to execute on or other issues arising under, such contracts or conditions or trends impacting certain of our key clients could adversely affect our business and results of operations.

As described in greater detail in the description of our business in Item 1 - "Business" of our Annual Report on Form 10-K for the year ended December 31, 2016 , filed with the SEC on February 14, 2017 , we have contracts with Anthem, Inc. ("Anthem") and the United States Department of Defense ("DoD") which represent 19% and 12% , respectively, of consolidated revenues for both the three and six months ended June 30, 2017 .

If one or more of our large clients either terminates or does not renew a contract for any reason or if the provisions of a contract with a large client are modified, renewed or otherwise changed with terms less favorable to us and if we are not able to replace lost business or revenue by generating new business that is comparably profitable to us or by executing other corporate strategies, our results of operations could be materially adversely affected and we could experience a negative reaction in the investment community resulting in stock price declines or other adverse effects.

Our contract with Anthem expires at the end of 2019 with a one year transition period through 2020. Based on recent statements made and other actions taken by Anthem's management, we believe it is unlikely that we will extend our contract with Anthem beyond the term of the current contract. If we do enter into a new contract with Anthem, it could involve

Table of Contents

significant rate relief, and would be on terms significantly less favorable to us than, the current contract. Anthem's decision whether to enter into a new contract with us, the terms of any new contract and the impact of non-renewal or new contract terms on our business will depend on a number of factors that we cannot currently anticipate or control, and could result in a material adverse effect on our business, cash flows and results of operations. The timing and extent of our elimination of the direct and indirect costs of servicing Anthem in the event we do not enter into a new contract will depend on a number of factors, including the extent to which we provide transition services after the current contract expires. Our inability to reduce our costs and otherwise mitigate the impact of the expiration of the Anthem contract could have a material adverse effect on our business, cash flows and results of operations.

In March 2016, Anthem filed a lawsuit against us setting forth certain allegations and claims for relief with respect to our pharmacy benefit management agreement with Anthem (see Part II - Item 1 - "Legal Proceedings"). While we believe Anthem's lawsuit is without merit, litigation and the potential outcome cannot be accurately or effectively predicted and at this time we are unable to provide a timetable or an estimate as to the potential outcome of this matter, which could result in a material adverse effect on our business, cash flows and results of operations.

In addition, if certain of our key clients are negatively impacted by business conditions or other economic trends, or if such clients are acquired, consolidated or otherwise fail to successfully maintain or grow their business, our business and results of operations could be adversely impacted.


Item 2.	Unregistered Sales of Equity Securities and Use of Proceeds

On May 17, 2017, we issued 2.0 million shares of our common stock in connection with an acquisition. We issued shares in reliance upon the exemption contained in Section 4(a)(2) of the Securities Act of 1933, as amended, as a transaction not involving a public offering.

The following is a summary of our stock repurchasing activity during the three months ended June 30, 2017 (share data in millions):



Period	Total number of shares purchased	Average price paid per share		Total number of shares purchased as part of a publicly announced program	Maximum number of shares that may yet be purchased under the program
4/1/2017 - 4/30/2017	5.8	$	64.13	5.8	60.1
5/1/2017 - 5/31/2017	7.1	60.48		7.1	53.0
6/1/2017 - 6/30/2017	5.6	63.05		5.6	47.4
Second Quarter 2017 Total	18.5	$	62.41	18.5

The repurchases disclosed in this table were made pursuant to the share repurchase program, originally announced in 2013, and, specifically, pursuant to a Rule 10b5-1 plan implemented on February 15, 2017 as well as through open market purchases. The Rule 10b5-1 plan was completed on June 30, 2017. As of June 30, 2017 , there were 47.4 million shares remaining under the share repurchase program. Additional share repurchases, if any, will be made through open market purchases, Rule 10b5-1 plans, accelerated share repurchases, privately negotiated transactions or other transactions in such amounts and at such times as we deem appropriate based upon prevailing market and business conditions and other factors.
