Walgreens Boots Alliance Reports Fiscal 2016 Third Quarter Results

DEERFIELD, Ill., 6 July 2016 – Walgreens Boots Alliance, Inc. (Nasdaq: WBA) today announced financial results for the third quarter and first nine months of fiscal year 2016 that ended 31 May 2016.

Executive Vice Chairman and CEO Stefano Pessina said, “We delivered solid results in the quarter while continuing to make progress in several key areas, including our work to develop long-term strategic relationships and pursue partnership opportunities. I’m pleased to report that since the quarter end we achieved our goal set four years ago of at least $1 billion in combined net synergies in fiscal year 2016 related to the strategic combination with Alliance Boots. This provides us with a strong platform to further enhance operating performance, to meet the challenges of the current volatility in many of our markets and to better position our company for long-term success.”

Overview of Third Quarter Results

Fiscal 2016 third quarter net earnings attributable to Walgreens Boots Alliance determined in accordance with GAAP decreased 15.3 percent to $1.1 billion compared with the same quarter a year ago, while GAAP net earnings attributable to Walgreens Boots Alliance per diluted share decreased 14.4 percent to $1.01 compared with the same quarter a year ago. The decreases in GAAP net earnings and GAAP net earnings per share reflect fluctuations in the quarterly fair value adjustments of the company’s AmerisourceBergen Corporation warrants.

Adjusted fiscal 2016 third quarter net earnings attributable to Walgreens Boots Alliance¹ increased 14.7 percent to $1.3 billion compared with the same quarter a year ago. Adjusted net earnings attributable to Walgreens Boots Alliance per diluted share for the quarter increased 15.7 percent to $1.18 compared with the same quarter a year ago. Fiscal 2016 third quarter earnings adjustments were a net increase to GAAP net earnings attributable to Walgreens Boots Alliance of $185 million or 17 cents per diluted share.

Net sales in the third quarter were $29.5 billion, an increase of 2.4 percent over the year-ago quarter, or 3.3 percent on a constant currency basis.

Combined net synergies were $330 million in the fiscal 2016 third quarter and $947 million in the first nine months of fiscal 2016. In June, the company achieved its goal set in 2012 to reach at least $1 billion in combined net synergies in fiscal 2016 relating to the strategic combination with Alliance Boots. This excludes the synergy benefits related to the company’s strategic, long-term relationship with AmerisourceBergen, the benefits of refinancing the legacy Alliance Boots indebtedness at a lower cost and the proposed Rite Aid acquisition.

Walgreens Boots Alliance GAAP operating cash flow totaled $2.1 billion in the third quarter, while the company generated free cash flow of $1.9 billion in the quarter.

Overview of Fiscal 2016 Year-to-Date Results

For the first nine months of fiscal 2016, net earnings attributable to Walgreens Boots Alliance determined in accordance with GAAP decreased 25.1 percent to $3.1 billion compared with the same period a year ago, while GAAP net earnings attributable to Walgreens Boots Alliance per diluted share decreased 28.7 percent to $2.88 compared with the same period a year ago. The decreases in GAAP net earnings and GAAP net earnings per share reflect fluctuations in the fair value adjustments of the company’s AmerisourceBergen warrants and the prior-year period, non-cash gain associated with the remeasurement to fair value on 31 December 2014 of the company’s previously-held equity investment in Alliance Boots.

Adjusted net earnings attributable to Walgreens Boots Alliance¹ for the first nine months of fiscal 2016 increased 23.3 percent to $3.8 billion compared with the same period a year ago. Adjusted net earnings attributable to Walgreens Boots Alliance per diluted share for the first nine months of fiscal 2016 increased 17.3 percent to $3.52 compared with the same period a year ago. Earnings adjustments in the first nine months of the fiscal year were a net increase to GAAP net earnings attributable to Walgreens Boots Alliance of $700 million or 64 cents per diluted share.

Net sales increased 18.4 percent to $88.7 billion for the first nine months of fiscal 2016 compared with the same period a year ago, largely due to the inclusion of Alliance Boots consolidated results for the entire period.

Walgreens Boots Alliance GAAP operating cash flow totaled $5.2 billion in the first nine months of fiscal 2016, while the company generated free cash flow of $4.3 billion during the period.

Rite Aid Acquisition

Walgreens Boots Alliance’s proposed acquisition of Rite Aid Corporation, which was announced 27 October 2015, is progressing as planned. The transaction is subject to the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other customary closing conditions.

2

On 1 June 2016, the company completed a public offering of $6 billion aggregate principal amount of unsecured, unsubordinated notes with varying maturities and interest rates. The company intends to use the net proceeds to fund a portion of the cash consideration payable in connection with its pending acquisition of Rite Aid, to retire a portion of Rite Aid’s existing debt and to pay related fees and expenses.

Walgreens Boots Alliance is continuing its integration planning and continues to expect the Rite Aid transaction to close in the second half of calendar 2016.

Company Outlook

The company raised the lower end of its guidance for fiscal year 2016 by 10 cents per share and now anticipates adjusted net earnings per diluted share attributable to Walgreens Boots Alliance of $4.45 to $4.55.

This guidance assumes no impact from the proposed acquisition of Rite Aid and related financing, and assumes current exchange rates for the rest of the fiscal year.

Third Quarter Business Segment Highlights

Retail Pharmacy USA:

Retail Pharmacy USA had third quarter total sales of $21.2 billion, an increase of 3.7 percent over the year-ago quarter. Sales in comparable stores increased 3.9 percent compared with the same quarter a year ago.

Pharmacy sales, which accounted for 67.4 percent of the division’s total sales in the quarter, increased 5.8 percent compared with the year-ago quarter, while comparable pharmacy sales increased 6.0 percent. The division filled 235 million prescriptions (including immunizations) adjusted to 30-day equivalents in the quarter, an increase of 3.9 percent over last year’s third quarter. Prescriptions filled in comparable stores increased 4.5 percent compared with the same quarter last year, primarily due to continued growth in Medicare Part D volume. The division’s retail prescription market share on a 30-day adjusted basis in the third quarter increased approximately 30 basis points over the year-ago quarter to 19.6 percent, as reported by IMS Health.

Comparable retail sales increased 0.1 percent in the third quarter compared with the year-ago period, primarily due to higher sales in the health and wellness and photo categories, partially offset by declines in certain convenience categories. The division is focused on profitable sales growth in future quarters, in part through a new, differentiated beauty offering. The first phase of these updates is in progress, with a rollout to more than 1,800 stores by the end of calendar 2016.

GAAP gross profit grew $76 million, or 1.4 percent, to $5.6 billion compared with the same quarter a year ago, while adjusted gross profit increased $99 million, or 1.8 percent, to $5.7 billion. These increases reflected increased pharmacy volume and the favorable impact of procurement efficiencies, partially offset by lower reimbursement rates.

3

GAAP third quarter selling, general and administrative expenses decreased by $60 million, or 1.3 percent, to $4.4 billion compared with the year-ago quarter. Adjusted selling, general and administrative expenses increased $45 million, or 1.1 percent, to $4.3 billion, demonstrating continuing benefits from the company’s cost transformation program.

GAAP operating income in the third quarter increased 13.2 percent over the year-ago quarter to $1.2 billion. Adjusted operating income in the third quarter increased 4.1 percent over the year-ago quarter to $1.4 billion.

Retail Pharmacy International:

Retail Pharmacy International had third quarter total sales of $3.2 billion, a decrease of 2.3 percent over the year-ago quarter due to currency translation, with total sales increasing by 3.4 percent on a constant currency basis.

On a constant currency basis, comparable store sales increased 0.2 percent compared with the year-ago quarter. Comparable pharmacy sales decreased 0.7 percent on a constant currency basis due in part to the negative impact of a reduction in pharmacy funding in the UK that was expected, and the loss of certain institutional sales contracts in Chile. Comparable retail sales increased 0.7 percent on a constant currency basis, reflecting strong performances in the Republic of Ireland and Thailand.

GAAP operating income in the third quarter increased 8.8 percent over the year-ago quarter to $223 million, while adjusted operating income increased 3.6 percent to $258 million, up 8.0 percent on a constant currency basis.

Pharmaceutical Wholesale:

Pharmaceutical Wholesale had third quarter total sales of $5.7 billion, an increase of 0.7 percent over the year-ago quarter. In April, the company sold Alliance Healthcare Russia to the Russian health and beauty retailer 36.6 in return for a 15 percent stake in the combined group. On a constant currency basis, excluding acquisitions and dispositions, comparable sales increased 6.3 percent. This was ahead of the company’s estimate of market growth weighted on the basis of country wholesale sales, and was particularly strong in a number of emerging markets.

On 18 March 2016 Walgreens Boots Alliance exercised warrants to purchase approximately 22.7 million shares of AmerisourceBergen common stock for an aggregate payment of approximately $1.17 billion. The transaction was funded using existing cash on hand. Following the exercise of these warrants, the company beneficially owns approximately 16 percent of the outstanding shares of AmerisourceBergen common stock (based on shares outstanding as of 30 April 2016, as reported by AmerisourceBergen in its most recent quarterly report). The company also continues to hold warrants to purchase an additional approximately 22.7 million shares of AmerisourceBergen common stock, which the company has the right to exercise beginning in March 2017.

Since the exercise of the warrants, the company accounts for its investment in AmerisourceBergen using the equity method of accounting, subject to a two-month reporting lag, with the net earnings attributable to its investment being classified within the operating income of Pharmaceutical Wholesale. As a result, the third quarter includes approximately two weeks of equity method income.

GAAP operating income in the third quarter decreased 9.9 percent over the year-ago quarter to $146 million. Adjusted operating income increased 4.7 percent to $179 million, up 7.6 percent on a constant currency basis, of which 4.7 percent was due to equity earnings in AmerisourceBergen.

Comparability of Results

Following the strategic combination with Alliance Boots on 31 December 2014, Walgreens Boots Alliance results for the three months ended 31 May 2015, and the three and nine months ended 31 May 2016, include the results of Alliance Boots on a fully consolidated basis, while the nine months ended 31 May 2015 includes the results of Alliance Boots for five months (January through May 2015) on a fully consolidated basis and as equity income from Walgreen Co.’s pre-closing 45 percent interest in Alliance Boots for four months (September through December 2014).

Walgreens Boots Alliance has organized its operations and reports results in three segments: Retail Pharmacy USA, Retail Pharmacy International and Pharmaceutical Wholesale. Segmental reporting includes results of operations, the allocation of synergy benefits including Walgreens Boots Alliance Development GmbH (WBAD) results, and the allocation of combined corporate costs for periods subsequent to 31 December 2014. The company has determined that it is impracticable to allocate historical results to the current segmental presentation. Accordingly, Retail Pharmacy USA segment results for periods prior to 31 December 2014 include all corporate costs of Walgreen Co., the full consolidated results of WBAD and equity income from Walgreen Co.’s pre-closing 45 percent interest in Alliance Boots.

Nine-month period-over-period comparisons of results require consideration of the foregoing factors and are not directly comparable.

The conference call will be simulcast through the Walgreens Boots Alliance investor relations website at: http://investor.walgreensbootsalliance.com.

SUPPLEMENTAL INFORMATION (UNAUDITED)

REGARDING NON-GAAP FINANCIAL MEASURES

(In millions, except per share amounts)

The following information provides reconciliations of the supplemental non-GAAP financial measures, as defined under SEC rules, presented in this press release to the most directly comparable financial measures calculated and presented in accordance with generally accepted accounting principles in the United States (GAAP). The company has provided the non-GAAP financial measures in the press release, which are not calculated or presented in accordance with GAAP, as supplemental information and in addition to the financial measures that are calculated and presented in accordance with GAAP.

These supplemental non-GAAP financial measures are presented because management has evaluated the company’s financial results both including and excluding the adjusted items or the effects of foreign currency translation, as applicable, and believe that the supplemental non-GAAP financial measures presented provide additional perspective and insights when analyzing the core operating performance of the company’s business from period to period and trends in the company’s historical operating results. These supplemental non-GAAP financial measures should not be considered superior to, as a substitute for or as an alternative to, and should be considered in conjunction with, the GAAP financial measures presented in the press release. The company does not provide a reconciliation for non-GAAP estimates on a forward-looking basis (including the information under “Company Outlook” above) where it is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing or amount of various items that would impact net earnings per diluted share, the most directly comparable forward-looking GAAP financial measure, including, for example, decreases (increases) in fair market value of warrants and changes in the LIFO provision, that have not yet occurred, are out of the company’s control and/or cannot be reasonably predicted. For the same reasons, the company is unable to address the probable significance of the unavailable information. Forward-looking non-GAAP financial measures provided without the most directly comparable GAAP financial measures may vary materially from the corresponding GAAP financial measures.

As a global company, Walgreens Boots Alliance’s operating results reported in U.S. dollars are affected by foreign currency exchange rate fluctuations because the underlying foreign currencies in which the company transacts change in value over time compared to the U.S. dollar; accordingly, the company presents certain constant currency financial information to provide a framework to assess how the company’s businesses performed excluding the impact of foreign currency exchange rate fluctuations. Foreign currency impact represents the difference in results that are attributable to fluctuations in the currency exchange rates used to convert the results for businesses where the functional currency is not the U.S. dollar. This impact is calculated by translating current period results at the currency exchange rates used in the comparable period in the prior year, rather than the exchange rates in effect during the current period. The company believes these measures should be considered a supplement to and not in lieu of the company’s performance measures calculated in accordance with GAAP. In the third quarter of fiscal 2016 compared to the prior year quarter, the company’s Retail Pharmacy International division’s comparable store sales on a reported currency basis decreased 5.4 percent, comparable pharmacy sales on a reported currency basis decreased 6.6 percent and comparable retail sales on a reported currency basis decreased 4.6 percent, and the company’s Pharmaceutical Wholesale division’s comparable sales excluding acquisitions and dispositions on a reported currency basis increased 4.6 percent.
