DEERFIELD, Ill., April 2, 2020—Walgreens Boots Alliance, Inc. (Nasdaq: WBA) today announced financial results for the second quarter of fiscal 2020, which ended February 29, 2020.

Executive Vice Chairman and CEO Stefano Pessina said, “We are pleased to report second quarter results exceeding our expectations, with sequential improvement in comparable U.S. prescription volume and retail sales. During these unprecedented times of global uncertainty, Walgreens Boots Alliance is on the front lines of combating the COVID-19 pandemic. Our number one priority is to continue to provide essential services, products and information at this critical moment of need, demonstrating our unwavering commitment to our customers and patients, and to our people.”

Overview of Second Quarter Results

Fiscal 2020 second quarter net earnings attributable to WBA decreased 18.2 percent to $946 million compared with the same quarter a year ago, while net earnings per share¹ decreased 14.0 percent to $1.07 compared with the same quarter a year ago.

Adjusted net earnings attributable to WBA² decreased 11.8 percent to $1.3 billion, on both a reported and constant currency basis, compared with the same quarter a year ago.

Sales in the second quarter were $35.8 billion, an increase of 3.7 percent from the year-ago quarter, and an increase of 4.1 percent on a constant currency basis. Effects from the COVID-19 pandemic began at the end of the second quarter and were not material to overall results.

Compared to the same quarter a year ago, operating income was $1.2 billion, a decrease of 18.7 percent, and adjusted operating income was $1.7 billion, a decrease of 12.0 percent, on both a reported and constant currency basis, reflecting lower U.S. pharmacy gross margin and year-over-year bonus changes, partially offset by cost savings from the Transformational Cost Management Program.

Net cash provided by operating activities was $1.4 billion in the second quarter and free cash flow was $1.1 billion.

For the first six months of fiscal 2020, net earnings attributable to WBA decreased 21.4 percent to $1.8 billion compared with the same period a year ago, while net earnings per share¹ decreased 16.8 percent to $2.01 compared with the same period a year ago.

Adjusted earnings per share for the first six months of fiscal 2020 were $2.88, a decrease of 6.6 percent on a reported basis and a decrease of 6.5 percent on a constant currency basis, compared with the same period a year ago.

Company Outlook

Prior to the COVID-19 pandemic, the company was on track to maintain its guidance for full-year fiscal 2020, of roughly flat growth in adjusted EPS, at constant currency rates, with a range of plus or minus 3 percent. Second quarter financial performance exceeded the company’s expectations. Although the COVID-19 situation is ultimately temporary, given the many rapidly changing variables related to the pandemic, at this time WBA is not in a position to accurately forecast the future impacts. The company will continue to closely assess and manage this situation, and will provide further updates in the next earnings report when both the potential positive and negative effects of the pandemic will be known in more detail.

Progress on Strategic Priorities

During the second quarter of fiscal 2020, and since the close of the quarter, the company made substantial progress on its four strategic priorities: accelerating digitalization; transforming and restructuring its retail offering; creating neighborhood health destinations; and the Transformational Cost Management Program.

Actions to Support Customers, Patients and Team Members During COVID-19

WBA has taken numerous steps to support customers, patients and team members during the COVID-19 pandemic. The following are some examples:

Business Divisions

Retail Pharmacy USA:

Retail Pharmacy USA had second quarter sales of $27.2 billion, an increase of 3.8 percent over the year-ago quarter. Sales in comparable stores increased 2.7 percent from the year-ago quarter. Comparable data in this press release exclude the favorable impact of the 2020 leap day.

Pharmacy sales increased 5.3 percent compared with the year-ago quarter, reflecting higher brand inflation and prescription volume, and specialty growth of 17.7 percent. Comparable pharmacy sales increased 3.7 percent. The division filled 296.8 million prescriptions, including immunizations, adjusted to 30-day equivalents in the quarter, an increase of 3.7 percent over the year-ago quarter. Prescriptions filled in comparable stores increased 4.9 percent compared with the same quarter a year ago.

The division’s retail prescription market share on a 30-day adjusted basis in the second quarter decreased approximately 50 basis points over the year-ago quarter to 21.0 percent, as reported by IQVIA.³

Retail sales decreased 0.3 percent in the second quarter compared with the year-ago period. Comparable retail sales were up 0.6 percent in the quarter, mostly due to strong growth in health and wellness, including a favorable cough, cold and flu season. Excluding tobacco and e-cigarettes, comparable retail sales increased 1.9 percent.

Gross profit decreased 4.3 percent compared with the same quarter a year ago and adjusted gross profit decreased 3.7 percent, with procurement savings, prescription growth and solid retail growth more than offset by reimbursement pressure.

Second quarter selling, general and administrative expenses (SG&A) as a percentage of sales decreased by 0.7 percentage point compared with the year-ago quarter. Adjusted SG&A as a percentage of sales decreased by 0.8 percentage point. Both decreases include savings from the Transformational Cost Management Program.

Operating income in the second quarter decreased 21.5 percent from the year-ago quarter to $963 million. Excluding costs related to the acquisition of Rite Aid stores and to the Transformational Cost Management Program, adjusted operating income in the second quarter decreased 12.9 percent from the year-ago quarter to $1.3 billion, reflecting the year-on-year bonus impact and a reimbursement contract true-up.

Retail Pharmacy International:

Retail Pharmacy International had second quarter sales of $3.1 billion, a decrease of 0.8 percent from the year-ago quarter, including a favorable currency impact of 0.9 percent. Sales decreased 1.7 percent on a constant currency basis, mainly due to a 1.2 percent decline in Boots UK sales and lower sales in Thailand and Chile.

Comparable pharmacy sales in Boots UK increased 1.8 percent on a constant currency basis, reflecting higher National Health Service (NHS) reimbursement, partially offset by lower prescription volume. Boots UK comparable retail sales decreased 4.6 percent on a constant currency basis. Overall, the business held share in its categories, in a declining market.

Gross profit increased 0.3 percent compared with the same quarter a year ago, including a favorable currency impact of 0.8 percent. Adjusted gross profit decreased 2.5 percent, on a constant currency basis, reflecting lower retail sales and margin in Boots UK.

SG&A as a percentage of sales increased 2.3 percentage points, including incremental costs associated with the Transformational Cost Management Program. Adjusted SG&A as a percentage of sales, on a constant currency basis, increased 1.6 percentage points. Both reflected the higher year-on-year bonus impact and higher technology investments.

Operating income in the second quarter decreased 31.4 percent from the year-ago quarter to $132 million, while adjusted operating income decreased 22.9 percent to $198 million, down 24.0 percent on a constant currency basis.

Pharmaceutical Wholesale:

Pharmaceutical Wholesale had second quarter sales of $6.1 billion, an increase of 5.7 percent from the year-ago quarter, including an adverse currency impact of 2.3 percent. On a constant currency basis, sales increased 8.0 percent, led by emerging markets and the UK.

Operating income in the second quarter was $136 million, which included $28 million from the company’s equity earnings in AmerisourceBergen. This compared with operating income of $100 million in the year-ago quarter, which included $83 million from the company’s equity earnings in AmerisourceBergen.

Adjusted operating income increased 4.6 percent to $235 million, up 5.2 percent on a constant currency basis, reflecting strong sales growth and a higher contribution from AmerisourceBergen, partially offset by lower gross margin.

Dividends Declared

During the second quarter, the company declared a quarterly dividend of 45.75 cents per share, unchanged from the previous quarter and an increase of 4 percent from the year-ago quarter. The dividend was payable March 12, 2020 to stockholders of record as of February 19, 2020.

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 have not yet occurred, are out of the company’s control and/or cannot be reasonably predicted, and that would impact diluted net earnings per share, the most directly comparable forward-looking GAAP financial measure. 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.

Constant currency

The company also presents certain information related to current period operating results in “constant currency,” which is a non-GAAP financial measure. These amounts are calculated by translating current period results at the foreign currency exchange rates used in the comparable period in the prior year. The company presents such constant currency financial information because it has significant operations outside of the United States reporting in currencies other than the U.S. dollar and this presentation provides a framework to assess how its business performed excluding the impact of foreign currency exchange rate fluctuations.

Comparable sales

Fiscal 2020 second-quarter comparable sales and prescriptions filled figures for the company’s Retail Pharmacy divisions exclude the benefit of this year’s leap day.

For the company’s Retail Pharmacy divisions, comparable stores are defined as those that have been open for at least twelve consecutive months without closure for seven or more consecutive days and without a major remodel or being subject to a natural disaster in the past twelve months. Relocated stores are not included as comparable stores for the first twelve months after the relocation. Acquired stores are not included as comparable stores for the first twelve months after acquisition or conversion, when applicable, whichever is later. Comparable store sales, comparable pharmacy sales and comparable retail sales refer to total sales, pharmacy sales and retail sales, respectively, in such stores. For the Retail Pharmacy USA division, comparable numbers of prescriptions refer to number of prescriptions in such stores. The method of calculating comparable sales varies across the retail industry. As a result, the company’s method of calculating comparable sales may not be the same as other retailers’ methods.

With respect to the Retail Pharmacy International division, comparable store sales, comparable pharmacy sales and comparable retail sales, are presented on a constant currency basis, which are non-GAAP financial measures. Refer to the discussion above in “Constant currency” for further details on constant currency calculations.

Key Performance Indicators

The company considers certain metrics, including all comparable metrics, number of prescriptions, number of 30-day equivalent prescriptions and number of locations at period end, to be key performance indicators because the company’s management has evaluated its results of operations using these metrics and believes that these key performance indicators presented provide additional perspective and insights when analyzing the core operating performance of the company from period to period and trends in its historical operating results. These key performance indicators 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 herein. These measures may not be comparable to similarly-titled performance indicators used by other companies.
