In the tables that follow, GAAP results and GAAP to non-GAAP reconciliations are presented. For more information related to non-GAAP financial measures, including adjustments made in the periods presented, please refer to the Supplemental Information Regarding Non-GAAP Financial Measures following the tables.

Fourth Quarter GAAP Results

• Revenue: In the fourth quarter of fiscal 2022, revenue was $61.2 billion, up 3.8 percent compared to the same quarter in the previous fiscal year, reflecting a 4.7 percent increase in U.S. Healthcare Solutions revenue and a 2.7 percent decrease in revenue within International Healthcare Solutions due to the negative impact of foreign currency translation.

• Gross Profit: Gross profit in the fiscal 2022 fourth quarter was $2.0 billion, a 4.1 percent decrease compared to the same period in the previous fiscal year. Gross profit was unfavorably impacted by LIFO expense of $104.8 million in the current year period versus a LIFO credit of $42.5 million in the previous fiscal year period and a decline in gross profit within International Healthcare Solutions due to the negative impact of foreign currency translation. The decrease was offset in part by an increase in gross profit in U.S. Healthcare Solutions. Gross profit as a percentage of revenue was 3.25 percent, a decline of 26 basis points from the prior year quarter.

• Operating Expenses: In the fourth quarter of fiscal 2022, operating expenses were $1.5 billion, up 1.6 percent from the same period last fiscal year, primarily a result of an increase in distribution, selling, and administrative expenses. Operating expenses as a percentage of revenue in the fiscal 2022 fourth quarter were 2.50 percent compared to 2.56 percent for the same period in the previous fiscal year.

• Operating Income: In the fiscal 2022 fourth quarter, operating income was $454.5 million versus $561.9 million in the prior year quarter due to the decrease in gross profit and increase in operating expenses.

• Interest Expense, Net: In the fiscal 2022 fourth quarter, net interest expense of $51.5 million was down 5.6 percent versus the prior year quarter due to an increase in interest income as a result of higher investment interest rates.

• Effective Tax Rate: The effective tax rate was 21.9 percent for the fourth quarter of fiscal 2022. This compares to 21.2 percent in the prior year quarter.

• Diluted Earnings Per Share: Diluted earnings per share was $1.40 in the fourth quarter of fiscal 2022 compared to $2.08 in the previous fiscal year fourth quarter.

• Diluted Shares Outstanding: Diluted weighted average shares outstanding for the fourth quarter of fiscal 2022 were 210.0 million, a 0.4 percent decline versus the prior fiscal year fourth quarter primarily due to share repurchases, partially offset by stock option exercises and restricted stock vesting.

Segment Discussion

The Company is organized geographically based upon the products and services it provides to its customers. In the first quarter of fiscal 2022, the Company re-aligned its reporting structure under two reportable segments: U.S. Healthcare Solutions and International Healthcare Solutions. U.S. Healthcare Solutions consists of the legacy Pharmaceutical Distribution Services reportable segment (excluding Profarma), MWI Animal Health, Xcenda, Lash Group, and ICS 3PL. International Healthcare Solutions consists of Alliance Healthcare, World Courier, Innomar, Profarma, and Profarma Specialty (until it was divested in June 2022). The Company’s previously reported segment results have been revised to conform to its re-aligned reporting structure.

U.S. Healthcare Solutions Segment

U.S. Healthcare Solutions revenue was $54.8 billion, an increase of 4.7 percent compared to the same quarter in the prior fiscal year primarily due to overall market growth and increased sales to specialty physician practices, and was partially offset by a decline in sales of commercial COVID-19 treatments. Segment operating income of $578.4 million in the fourth quarter of fiscal 2022 was up 14.0 percent compared to the same period in the previous fiscal year due to an increase in gross profit, primarily due to sales to specialty physician practices and fees earned from the distribution of government-owned COVID-19 treatments.

International Healthcare Solutions

Revenue in International Healthcare Solutions was $6.4 billion in the fourth quarter of fiscal 2022, a decrease of 2.7 percent compared to the same period in the prior fiscal year. Operating income within International Healthcare Solutions decreased 12.6 percent to $163.1 million in the fourth quarter of fiscal 2022. The period over period declines were due to the negative impact of foreign currency translation resulting from our Alliance Healthcare business.

Fiscal Year 2022 Summary Results

Summary Fiscal Year GAAP Results

In fiscal year 2022, GAAP diluted EPS was $8.04 compared to $7.39 in the prior fiscal year. Revenue increased 11.5 percent from last fiscal year to $238.6 billion. Gross profit increased 19.5 percent to $8.3 billion primarily due to increases in gross profit within International Healthcare Solutions, including the full year impact of the June 2021 Alliance Healthcare acquisition, and within U.S. Healthcare Solutions, partially offset by a LIFO expense in the current year versus a credit in the previous fiscal year and less favorable gains from antitrust litigation settlements. Operating expenses increased 29.2 percent primarily due to an increase in expenses as a result of the June 2021 acquisition of Alliance Healthcare. Operating income increased 0.5 percent due to higher gross profit, which was largely offset by higher operating expenses. Diluted weighted average shares outstanding in fiscal 2022 were 211.2 million, up 1.3 percent from the prior fiscal year resulting from stock option exercises, restricted stock vesting, and the June 2021 issuance of 2 million shares of the Company's common stock to Walgreens Boots Alliance, Inc. ("WBA") in connection with the acquisition of Alliance Healthcare, partially offset by share repurchases.

Summary Fiscal Year Adjusted (non-GAAP) Results

Adjusted operating expenses increased 33.5 percent to $5.2 billion primarily due to the June 2021 acquisition of Alliance Healthcare. Adjusted operating income increased 19.5 percent to $3.2 billion due to the increase in gross profit associated with the June 2021 acquisition of Alliance Healthcare, increased sales to specialty physician practices, and fees earned from the distribution of government-owned COVID-19 treatments.
