Third Quarter GAAP Results

Gross Profit: Gross profit in the third quarter of fiscal 2021 was $1.9 billion, a 54.0 percent increase compared to the same period in the previous fiscal year. Gross profit was favorably impacted by increases in gross profit in Pharmaceutical Distribution Services and Other, a LIFO credit in the current year quarter in comparison to a LIFO expense in the prior year quarter and increases in gains from antitrust litigation settlements. Gross profit as a percentage of revenue was 3.54%, an increase of 84 basis points from the prior year quarter primarily driven by the acquisition of Alliance Healthcare, an increase in sales of specialty products in Pharmaceutical Distribution Services and growth in some of the Company's higher margin businesses.

Operating Expenses: In the third quarter of fiscal 2021, operating expenses were $1,267.5 million, a 54.4 percent increase compared to the same period last fiscal year. The increase in operating expenses was primarily due to the acquisition of Alliance Healthcare and a $124.3 million accrual related to opioid settlement discussions. Operating expenses as a percentage of revenue in the fiscal 2021 third quarter were 2.37 percent, compared to 1.81 percent for the same period in the previous fiscal year primarily due to the items mentioned above.

Operating Income: In the fiscal 2021 third quarter, operating income increased to $620.7 million from $404.8 million. Operating income as a percentage of revenue was 1.16 percent in the third quarter of fiscal 2021, compared to 0.89 percent for the same period in the previous fiscal year primarily due to the acquisition of Alliance Healthcare and growth in some of the Company's higher margin businesses.

Interest Expense, Net: In the fiscal 2021 third quarter, net interest expense of $51.3 million was up 36.0 percent versus the prior year quarter due to the issuance of debt to finance a portion of the acquisition of Alliance Healthcare.

Effective Tax Rate: The effective tax rate was 48.5 percent for the third quarter of fiscal 2021 primarily due to tax reform in the United Kingdom. This compares to 16.5 percent in the prior year quarter, which was favorably impacted by a discrete tax benefit.

Diluted Earnings Per Share: Diluted earnings per share was $1.40 in the third quarter of fiscal 2021 compared to $1.41 in the previous fiscal year's third quarter.

Diluted Shares Outstanding: Diluted weighted average shares outstanding for the third quarter of fiscal 2021 were 208.9 million, a 1.6 percent increase versus the prior fiscal year third quarter resulting from stock option exercises, restricted stock vesting, and the issuance of 2 million Company shares to Walgreens for the June 2021 acquisition of Alliance Healthcare.

Third Quarter Adjusted (non-GAAP) Results

Revenue: No adjustments were made to the GAAP presentation of revenue.

Adjusted Gross Profit: Adjusted gross profit in the fiscal 2021 third quarter was $1.6 billion, which was up 32.0 percent compared to the same period in the previous fiscal year due to the Alliance Healthcare acquisition and increases in gross profit in Pharmaceutical Distribution Services and Other.

Diluted weighted average shares outstanding for the third quarter of fiscal 2021 were 208.9 million, a 1.6 percent increase versus the prior fiscal year third quarter resulting from stock option exercises, restricted stock vesting, and the issuance of 2 million Company shares to Walgreens for the June 2021 acquisition of Alliance Healthcare.

Please refer to the Supplemental Information Regarding Non-GAAP Financial Measures following the tables for additional information.

Fiscal Year 2021 Expectations on an Adjusted (non-GAAP) Basis

Adjusted Diluted EPS to be in the range of $9.15 to $9.30, raised from the previous range of $8.90 to $9.10.

Additional expectations now include:

Adjusted operating expense to be approximately $3.9 billion, up from growth in the high-single digit percent range;
Adjusted operating income to be approximately $2.6 billion, up from growth in the high-single digit percent range;
- Pharmaceutical Distribution Services operating income growth to be in the low-double digit percent range, up from growth in the high-single digit percent range;

SUPPLEMENTAL INFORMATION REGARDING

NON-GAAP FINANCIAL MEASURES

To supplement the financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), the Company uses the non-GAAP financial measures described below. The non-GAAP financial measures should be viewed in addition to, and not in lieu of, financial measures calculated in accordance with GAAP. These supplemental measures may vary from, and may not be comparable to, similarly titled measures by other companies.

The non-GAAP financial measures are presented because management uses non-GAAP financial measures to evaluate the Company's operating performance, to perform financial planning, and to determine incentive compensation. Therefore, the Company believes that the presentation of non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors. The presented non-GAAP financial measures exclude items that management does not believe reflect the Company's core operating performance because such items are outside the control of the Company or are inherently unusual, non-operating, unpredictable, non-recurring, or non-cash. We have included the following non-GAAP earnings-related financial measures in this release:

Adjusted gross profit and adjusted gross profit margin: Adjusted gross profit is a non-GAAP financial measure that excludes gains from antitrust litigation settlements, LIFO expense (credit), and certain PharMEDium shutdown and remediation costs. Adjusted gross profit margin is the ratio of adjusted gross profit to total revenue. Management believes that these non-GAAP financial measures are useful to investors as a supplemental measure of the Company's ongoing operating performance. Gains from antitrust litigation settlements and LIFO expense (credit) are excluded because the Company cannot control the amounts recognized or timing of these items. PharMEDium remediation costs are excluded because they were unpredictable expenses. PharMEDium shutdown costs are excluded because they were unusual and non-recurring. Gains from antitrust litigation settlements relate to the settlement of lawsuits that have been filed against brand pharmaceutical manufacturers alleging that the manufacturer, by itself or in concert with others, took improper actions to delay or prevent generic drugs from entering the market. The PharMEDium remediation costs relate to costs incurred in connection with suspended production activities following U.S. Food and Drug Administration inspections. PharMEDium shutdown costs were costs incurred in connection with the permanent shutdown of the PharMEDium business. LIFO expense (credit) is affected by changes in inventory quantities, product mix, and manufacturer pricing practices, which may be impacted by market and other external influences.

Adjusted operating expenses and adjusted operating expense margin: Adjusted operating expenses is a non-GAAP financial measure that excludes acquisition-related intangibles amortization, employee severance, litigation, and other, certain PharMEDium shutdown and remediation costs, impairment of PharMEDium assets, and a contingent consideration adjustment. Adjusted operating expense margin is the ratio of adjusted operating expenses to total revenue. Acquisition-related intangibles amortization is excluded because it is a non-cash item and does not reflect the operating performance of the acquired companies. We exclude employee severance amounts that relate to unpredictable and/or non-recurring business restructuring. We exclude the amount of litigation settlements and other expenses, as well as PharMEDium shutdown and remediation costs, a contingent consideration adjustment and the impairment of PharMEDium assets, that are unusual, non-operating, unpredictable, non-recurring or non-cash in nature because we believe these exclusions facilitate the analysis of our ongoing operational performance. The contingent consideration adjustment reflects an adjustment made by one of the Company's non-wholly-owned subsidiaries, Profarma Distribuidora de Produtos Farmacêuticos S.A., of its previous estimate of contingent consideration related to the purchase price of a prior business acquisition.

Adjusted operating income and adjusted operating income margin: Adjusted operating income is a non-GAAP financial measure that excludes the same items that are described above and excluded from adjusted gross profit and adjusted operating expenses. Adjusted operating income margin is the ratio of adjusted operating income to total revenue. Management believes that these non-GAAP financial measures are useful to investors as a supplemental way to evaluate the Company's performance because the adjustments are unusual, non-operating, unpredictable, non-recurring or non-cash in nature.

Adjusted income before income taxes: Adjusted income before income taxes is a non-GAAP financial measure that excludes the same items that are described above and excluded from adjusted operating income. In addition, the loss on the currency remeasurement of the deferred tax asset relating to Swiss tax reform in the three and nine months ended June 30, 2021 and the loss on the early retirement of debt in the three and nine months ended June 30, 2020 are excluded from adjusted income before income taxes because these amounts are unusual, non-operating, and non-recurring. Management believes that this non-GAAP financial measure is useful to investors because it facilitates the calculation of the Company's adjusted effective tax rate.

Adjusted effective tax rate: Adjusted effective tax rate is a non-GAAP financial measure that is determined by dividing adjusted income tax expense/benefit by adjusted income before income taxes. Management believes that this non-GAAP financial measure is useful to investors because it presents an effective tax rate that does not reflect unusual, non-operating, unpredictable, non-recurring, or non-cash amounts or items that are outside the control of the Company.

Adjusted income tax expense: Adjusted income tax expense is a non-GAAP financial measure that excludes the income tax expense associated with the same items that are described above and excluded from adjusted income before income taxes. Certain discrete tax benefits primarily attributable to the income tax deduction recognized in connection with the permanent shutdown of PharMEDium as well as the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act") are also excluded from adjusted income tax expense for the three and nine months ended June 30, 2020 and the nine months ended June 30, 2021. Further, certain expenses relating to tax reform in the United Kingdom and Switzerland are excluded from adjusted income tax expense for the three and nine months ended June 30, 2021. Management believes that this non-GAAP financial measure is useful to investors as a supplemental way to evaluate the Company's performance because the adjustments are unusual, non-operating, unpredictable, non-recurring or non-cash in nature.

Adjusted net income/loss attributable to noncontrolling interests: Adjusted net income/loss attributable to noncontrolling interests excludes the non-controlling interest portion of acquisition-related intangibles amortization and a contingent consideration adjustment. Management believes that this non-GAAP financial measure is useful to investors because it facilitates the calculation of adjusted net income attributable to ABC.

Adjusted net income attributable to ABC: Adjusted net income attributable to ABC is a non-GAAP financial measure that excludes the same items that are described above. Management believes that this non-GAAP financial measure is useful to investors as a supplemental way to evaluate the Company's performance because the adjustments are unusual, non-operating, unpredictable, non-recurring or non-cash in nature.

Adjusted diluted earnings per share: Adjusted diluted earnings per share excludes the per share impact of adjustments including gains from antitrust litigation settlements; LIFO expense (credit); PharMEDium shutdown and remediation costs; acquisition-related intangibles amortization; employee severance, litigation, and other; impairment of PharMEDium assets; the loss on the currency remeasurement related to Swiss tax reform; and a contingent consideration adjustment, in each case net of the tax effect calculated using the applicable effective tax rate for those items. In addition, the per share impact of certain discrete tax benefits primarily attributable to the income tax deduction recognized in connection with the permanent shutdown of PharMEDium as well as the CARES Act for the nine months ended June 30, 2020 and the nine months ended June 30, 2021, and the per share impact of certain expenses relating to tax reform in the United Kingdom and Switzerland are also excluded from adjusted diluted earnings per share for the three and nine months ended June 30, 2021. Management believes that this non-GAAP financial measure is useful to investors because it eliminates the per share impact of the items that are outside the control of the Company or that we consider to not be indicative of our ongoing operating performance due to their inherent unusual, non-operating, unpredictable, non-recurring, or non-cash nature.

In addition, the Company updated its non-GAAP fiscal year 2021 guidance for diluted earnings per share, operating expense, operating income and adjusted free cash flow, and has previously provided non-GAAP fiscal year 2021 guidance for effective income tax rate. The guidance for each metric excludes the same or similar items as those that are excluded from the historical non-GAAP financial measures, as well as significant items that are outside the control of the Company or inherently unusual, non-operating, unpredictable, non-recurring or non-cash in nature. For fiscal year 2021, we have defined the non-GAAP financial measure of adjusted free cash flow as net cash provided by operating activities, excluding other significant unpredictable or non-recurring cash payments or receipts relating to legal settlements, minus capital expenditures. For the nine months ended June 30, 2021 adjusted free cash flow of $1,235.9 million consisted of net cash provided by operating activities of $1,656.8 million minus capital expenditures of $273.4 million and the gains from antitrust litigation settlements of $147.4 million. The Company does not provide forward looking guidance on a GAAP basis for such metrics because certain financial information, the probable significance of which cannot be determined, is not available and cannot be reasonably estimated. For example, LIFO expense (credit) is largely dependent upon the future inflation or deflation of brand and generic pharmaceuticals, which is out of the Company's control, and acquisition-related intangibles amortization depends on the timing and amount of future acquisitions, which cannot be reasonably estimated. Similarly, the timing and amount of litigation settlements is unpredictable and non-recurring.
