Executive Vice President and Chief Financial Officer at Laboratory Co. of America
Thank you, Adam. I'm going to start my comments with a review of our second quarter results, followed by a discussion of our performance in each segment and conclude with an update on our full-year guidance. For reference, we have also included additional business information that can be found in our supplemental deck on our Investor Relations website.
With the spin completed on June 30, we have treated Fortrea as discontinued operations in the second quarter. All my comments will reflect the current business and have been adjusted to exclude Fortrea in prior periods for comparative purposes.
Revenue for the quarter was $3 billion, an increase of 3.8% compared to last year, primarily due to organic base business growth and the impact from acquisitions, partially offset by lower COVID testing. The Base Business grew 12.7% compared to the Base Business last year, while COVID testing revenue was down 88% as we performed an average of 3,000 PCR tests per day in the quarter. Organically, in constant currency, the Base Business grew 10.8%, benefiting from the Ascension lab management agreement, which contributed approximately 5% of the organic growth.
As a reminder, the outreach business that we acquired from Ascension is treated as an acquisition, while the lab management agreement is treated as organic growth.
Operating income for the quarter was $266 million or 8.8% of revenue. During the quarter, we had $52 million of amortization and $131 million of restructuring charges and special items, primarily related to the spin of Fortrea, acquisitions and LaunchPad initiatives. Excluding these items, adjusted operating income in the quarter was $448 million or 14.8% of revenue compared to $548 million or 18.7% last year.
The decrease in adjusted operating income was due to lower COVID testing. The margin decline was also negatively affected by the mixed impact from the Ascension lab management agreement. Excluding these items, margins would have been up slightly as the benefit of demand and LaunchPad savings were partially offset by higher personnel expense and increased R&D investments in oncology.
Our LaunchPad initiatives continues to be on track to deliver $350 million of savings over the three-year period ending 2024. In addition, the Company is implementing actions in the third quarter to take out $25 million of annualized stranded costs throughout the enterprise as a result of the spin.
The tax rate for the quarter was 24.3%. The adjusted tax rate for the quarter was 23.9% compared to 25.3% last year. The lower adjusted rate was primarily due to R&D tax credits. We continue to expect our full-year adjusted tax rate to be approximately 24%.
Net earnings for the quarter from continuing operations were $155 million or $1.74 per diluted share. Adjusted EPS were $3.42 in the quarter, down 15% from last year due to lower COVID testing earnings as Base Business adjusted EPS was up approximately 18%.
Operating cash flow from continuing operations was $280 million in the quarter, which was burdened by approximately $65 million of spin-related items. Operating cash flow of $280 million is down from $548 million a year ago, primarily due to lower COVID testing earnings and spin-related items. In addition, higher working capital requirements that are timing-related were partially offset by higher Base Business earnings.
Capital expenditures totaled $103 million, down from $140 million last year. For the full year, we continue to expect that capital expenditures will be approximately 3.5% of Base Business revenue. Free cash flow from continuing operations for the quarter was $177 million, including approximately $65 million of spin-related items.
The Company invested $137 million in acquisitions and paid out $65 million in dividends. While the Company did not repurchase shares in the second quarter, we announced $1 billion accelerated share repurchase program that we expect to put in place in the third quarter and be completed by year-end.
At quarter-end, we had $1.9 billion in cash, including the $1.6 billion dividend from Fortrea spin, while debt was $5.3 billion. Our leverage was 2.6 times gross debt to trailing 12 months adjusted EBITDA.
Now, I'll review our segment performance beginning with Diagnostics Laboratories. Revenue for the quarter was $2.3 billion, an increase of 3.8% compared to last year, driven primarily by organic growth of 1.8% and acquisitions of 2.2%. The Base Business grew organically by 13.5% compared to the Base Business last year, while COVID testing revenue was down 88%. The Ascension lab management agreement contributed approximately 7% of the growth.
Total volume increased 1.4% compared to last year as acquisition volume grew 2.5%, partially offset by the organic volume of minus 1.1% due to COVID testing. Base Business volume grew 8.1% compared to the Base Business last year, including the benefit from acquisitions of 2.7%. The strong year-over-year growth rate was also aided by lower-than-normal volume in the second quarter of 2022 due to Omicron. Price mix increased 2.4% versus last year, primarily due to organic Base Business growth of 6.8%, partially offset by lower COVID testing of 3.9%. Base Business organic price mix was up 8% compared to Base Business last year, benefiting from the Ascension lab management agreement of approximately 7%.
Diagnostics Laboratories' adjusted operating income for the quarter was $410 million or 17.5% of revenue compared to $516 million or 22.9% last year. The decrease in adjusted operating income was due to lower COVID testing, while the margin decline was also negatively impacted by the mix impact from Ascension. Base Business margin excluding the mix impact of Ascension was up approximately 40 basis points as the benefit of organic growth and LaunchPad savings were partially offset by higher personnel expense.
Now, I'll review our segment performance of Biopharma Laboratory Services. Revenue for the quarter was $699 million, an increase of 3.1% compared to last year, primarily due to an increase in organic revenue of 2.1% and foreign currency of 1.5%. The increase in organic revenue was negatively impacted by approximately 5% due to the previously communicated NHP-related supply constraints in our Early Development Research Laboratories business.
Adjusted operating income for the segment was $105 million or 15% of revenue compared to $93 million or 13.7% last year. The increase in adjusted operating income and margin was due to organic demand and LaunchPad savings, partially offset by higher personnel expense. We ended the quarter with backlog of $8 billion and we expect approximately $2.5 billion of this backlog to convert into revenue over the next 12 months.
Now, I'll discuss our 2023 full-year guidance, which assumes foreign exchange rates effective as of June 30, 2023 for the full year. The enterprise guidance also includes the impact from currently anticipated capital allocation with free cash flow targeted for acquisitions, share repurchases and dividends. In addition, the guidance includes the $1 billion accelerated share repurchase program with proceeds from the spin. Excluding Fortrea, our current enterprise guidance for revenue, earnings and cash flow remains unchanged from our prior guidance given in April.
Enterprise revenue was in line with Diagnostics Laboratories slightly up, while Biopharma Laboratory Services is slightly down. We expect Enterprise revenue to grow 1.5% to 3% compared to 2022. This increase reflects the Base Business growing 11.3% to 12.6%, while COVID testing is expected to decline 85% to 89%. We expect Diagnostics Laboratories revenue to be up 0.5% to 1.5% compared to 2022. This is a 25 basis point increase at the midpoint from our April guidance as the Base Business outlook has improved, partially offset by lower COVID testing. This guidance includes the expectation that the Base business will grow 13.2% to 14.2%, which includes approximately 5% growth from Ascension. The Base Business has improved from our April guidance based on stronger demand. We continue to expect Diagnostics Laboratories Base Business margin to be slightly up in 2023 versus 2022, including the unfavorable mix impact from Ascension.
We expect Biopharma Laboratory Services revenue to grow 3% to 4.5% compared to 2022. This guidance includes the positive impact from foreign currency of 150 basis points. The midpoint of our guidance range is down approximately 75 basis points from the midpoint of our April guidance, but implies around 9.5% growth in the second half of the year as we expect favorable growth in both Central Laboratories and Early Development Research Laboratories. We also expect that the segment margin will be flat to slightly up in 2023 compared to 2022.
Our guidance range for adjusted EPS is $13 to $14, which is consistent with our April guidance, excluding Fortrea and including the impact from the accelerated share repurchase program. Free cash flow from continuing operations, excluding spin-related items, is expected to be between $800 million to $1 billion, in line with our prior guidance, excluding Fortrea.
In summary, we expect to drive continued profitable growth in our Base Business. We expect to continue to use our free cash flow generation for acquisitions that supplement our organic growth, while also returning capital to shareholders through our share repurchase program and dividends.
Operator, we will now take questions.
