James F. Cleary
Executive Vice President and Chief Financial Officer at Cencora
Thanks, Steve. Good morning and good afternoon, everyone. In our second quarter, AmerisourceBergen delivered strong financial performance as our businesses continued executing and delivering a differentiated value proposition to our customers and partners. Operationally, we are focused on increasing efficiency throughout the organization, while continuing to prioritize growth and ensuring that we are innovating to support the needs of our customers across our business.
Additionally, we continue to be focused on making thoughtful and strategic investments to power our long-term growth, supported by our strong balance sheet and free cash flow generation.
Before I turn to our second quarter results, as a reminder, my remarks today will focus on our adjusted non-GAAP financial results, unless otherwise stated. For a detailed discussion of our GAAP results, please refer to our earnings press release.
Turning now to our second quarter results. AmerisourceBergen finished the quarter with adjusted diluted EPS of $3.50, an increase of nearly 9% over the prior year quarter. This solid growth was driven by strong performance in our U.S. Healthcare Solutions segment, which more than offset the gross profit headwind from lapping the peak of COVID-19 therapy contributions in the prior year; good operating performance in our International Healthcare Solutions segment, which helped to offset some of the foreign exchange rate pressure; and a lower share count due to our opportunistic share repurchases during the past year.
Our consolidated revenue was $63.5 billion, up 10%, driven by growth in our U.S. Healthcare Solutions segment and offset by a slight decline in our International Healthcare Solutions segment, which was negatively impacted by foreign exchange rates and the divestiture of Profarma Specialty in June 2022. On a constant currency basis, consolidated revenue grew 11%.
Consolidated gross profit was $2.4 billion, up 6% due to growth in both segments. Consolidated gross profit margin was 3.71%, a decline of 13 basis points due primarily to lower COVID treatment contributions and mix in the quarter. Consolidated operating expenses were $1.4 billion, up 9% due to higher distribution, selling and administrative expenses. As expected, our year-over-year operating expense growth rate slowed sequentially from the first quarter.
As we have called out previously, in the second half, we will lap the inflationary pressures that began in the prior year March quarter. We will see operating expense growth slow significantly, particularly in the fourth quarter, due in part to incremental expense management actions taken, which put us on track to have a more normal growth rate in the mid-single-digit percent range for the full year.
We continue to focus on leveraging our existing capabilities and scale to create efficiencies, while also investing in our talent and growth initiatives to drive long-term sustainable growth and value creation for all our stakeholders.
Consolidated operating income was $932 million, an increase of approximately 2% compared to the prior year quarter or up 4% on a constant currency basis. Our operating income growth was driven by solid performance in the U.S. Healthcare Solutions segment, which offset currency-related pressures in the International Healthcare Solutions segment. I will discuss more detailed segment-level business drivers when reviewing segment-level results.
Moving now to our net interest expense. For the second quarter, net interest expense was $64 million, an increase of 21%, which was anticipated and we indicated would occur on our February earnings call. For the remainder of the year, we would expect quarterly net interest expense to be similar to this quarter.
Turning now to income taxes. Our effective income tax rate was 19% compared to 21% in the prior year quarter. We expect our effective income tax rate to be towards the lower end of our range of 20% to 21% for the fiscal year with higher tax rates in the next two quarters.
Turning to diluted share count. Our diluted share count was 204.3 million shares, a 3.6% decrease compared to the second quarter of fiscal 2022, driven by share repurchases we completed over the last 12 months.
Regarding our cash balance and free cash flow. We ended the quarter with approximately $1.5 billion of cash. In the quarter, we repaid the remaining $675 million of short-term debt related to the Alliance Healthcare acquisition, fulfilling our commitment to the ratings agencies to pay down two-thirds of the acquisition debt within two years of closing the acquisition.
For the first six months of the fiscal year, adjusted free cash flow was $1.1 billion, and we remain on track to achieve our adjusted free cash flow guidance of approximately $2 billion for the fiscal year.
This completes the review of our consolidated results. Now I'll turn to our segment results for the second quarter.
U.S. Healthcare Solutions segment revenue was $56.7 billion, up approximately 11% for the quarter, with broad-based growth across our customer base, including sales to our largest customers and sales of specialty products to physician practices and health systems. This growth was moderated by a decline in sales of COVID-19 treatments versus the prior year quarter.
U.S. Healthcare Solutions segment operating income increased by 3.6% to $756 million, driven by growth in specialty and across our distribution businesses as utilization trends continued to be strong. Additionally, in the quarter, we had good results in our Animal Health business, which is in line with the normalization that we foreshadowed on our February earnings call.
As a reminder, the U.S. Healthcare Solutions segment is lapping the March 2022 peak quarter for COVID-19 treatment contributions. Taking a step back, if you look at the segment year-to-date, for the six months ended in March, U.S. segment operating income was up 5.6% for the first half of 2023 versus the first half of 2022, if you exclude COVID-19 treatment contributions from both periods.
I will now turn to our International Healthcare Solutions segment. In the quarter, International Healthcare Solutions revenue was $6.8 billion, down 0.2% on a reported basis or up 12% on a constant currency basis. The as-reported decline reflects the divestiture of Profarma Specialty and unfavorable foreign exchange rates compared to the prior year quarter.
International Healthcare Solutions' operating income was $176 million, down approximately 6% on a reported basis, driven by a decline at Alliance Healthcare due to the effect of foreign currency exchange rates as well as the June 2022 divestiture of Profarma Specialty, which represented 3% of segment level operating income in the prior year quarter.
The decline was offset in part by strong growth at World Courier and the contribution from PharmaLex in the quarter. In the quarter, World Courier continued to perform well as the business saw good trends and demand for international shipments. On a constant currency basis, the International Healthcare Solutions segment delivered 7% operating income growth.
That completes the review of our segment level results. I will now discuss our updated fiscal 2023 guidance expectations. As a reminder, we do not provide forward-looking guidance on a GAAP basis, so the following metrics are provided on an adjusted non-GAAP basis. I will also provide certain guidance metrics on a constant currency basis. Full details of our fiscal 2023 guidance can be found on pages 8 and 9 of our earnings presentation on our Investor Relations website.
Starting with revenue, we are raising our consolidated revenue guidance to a range of 6% to 8% growth to reflect the strong revenue growth we saw in the first half of the year in the U.S. Healthcare Solutions segment and favorable currency movements in the International Healthcare Solutions segment relative to our prior guidance. We now expect revenue growth in the U.S. Healthcare Solutions segment to be approximately 7% to 8% or towards the higher end of our previous range of 6% to 8% growth. In the International Healthcare Solutions segment, we are raising our as-reported revenue guidance to a range of a 3% decline to flat, up from our previous expectation, about 1% to 5% decline.
Moving to operating income; we are raising our consolidated operating income guidance to a range of 2% to 4% growth from the previous range of 0% to 3% growth to reflect the strong core performance in the U.S. Healthcare Solutions segment. In the second quarter, COVID-19 treatments contributed $0.11 to our consolidated EPS, with about $0.09 in the U.S. and $0.02 in the International segment.
COVID treatment contributions in the quarter were slightly higher than our expectations, bringing our total contribution to $0.23 for the first half of the year, and we now expect the contribution from COVID-19 treatment distribution for the full fiscal year to be around $0.30 compared to our previous expectation of $0.25 to $0.30. We expect the small remaining contribution to be in the U.S. segment.
On an as-reported basis, we are raising our U.S. segment operating income growth to be in the range of 3% to 5%, up from our prior range of 1% to 4%, to reflect the continued strength and execution of our core business. Given our expectations for the core U.S. business, we are increasing our guidance for U.S. Healthcare Solutions segment operating income growth, excluding COVID, to be in the range of 6% to 8%, an increase from our previous expectation for growth of 5% to 7%.
This metric reflects the core performance of our U.S. segment, which represents roughly 80% of our consolidated operating income and helps provide visibility beyond the diminishing transitory contributions from distributing COVID treatments.
Finally, we now expect weighted average diluted share count to be approximately 205 million shares, down from our prior expectation of approximately 206 million shares, due to lower than anticipated dilution to-date. As a result of these updates, we are raising our full year diluted EPS guidance to a range of $11.70 to $11.90, up from our prior range of $11.50 to $11.75, representing growth of 6% to 8% on an as reported basis or 11% to 13%, excluding COVID-19 treatment contributions.
Before I turn to my closing remarks, I would like to provide a brief update on how AmerisourceBergen is working to help advance ESG initiatives across our industry. Recently, we partnered with the International Federation of Pharmaceutical Wholesalers and IQVIA to develop an industry ESG framework. In this framework, we leveraged our experience, reach-in relationships to help support pharmaceutical wholesalers aligning on and advancing key ESG initiatives.
Through this framework, IFPW members share best practices on key topics, including environmental stewardship, human capital management and health equity. We look forward to continuing to collaborate with the IFPW to move this important initiative forward.
In closing, AmerisourceBergen has a strong track record of execution and performance. We have delivered strong performance in the first half of our fiscal year and our updated fiscal 2023 guidance reflects the continued strength and resilience of our business. We are well positioned to continue deploying capital internally and externally to advance our business while being good stewards of shareholder capital.
I want to thank our purpose-driven team members and leaders for their strong execution and commitment to efficiency, growth, collaboration and innovation to help create differentiated value for all our stakeholders.
Now, I'll turn the call over to the operator to open the line for questions. Operator?
