Adam H. Schechter
Chairman, President and Chief Executive Officer at Laboratory Co. of America
Thank you, Christin, and good morning, everyone. Thank you for joining us as we review our third quarter financial performance and progress against our strategy. Before discussing our results, we'd like to acknowledge the communities across the Southeast and Mid-Atlantic, including our home state of North Carolina, which continues to face the devastating effects of Hurricanes Helene and Milton. Our thoughts are with those impacted, including our employees and residents of those communities across several states who are grappling with a long recovery ahead. We continue to support relief and recovery efforts as a member of the American Red Cross Disaster Response program. Turning to our results for the quarter. We continue to perform very well across both Diagnostics Laboratories and Biopharma Laboratory Services.
Our results reflect strong growth in diagnostics and Central Laboratories, driven by strong volume and core performance and by advancements in science, technology and innovation. Let's start by reviewing our financial results. Revenue in the quarter was $3.3 billion, an increase of 7% compared to the third quarter of 2023. Diagnostics continued to deliver strong revenue growth, up 9%, driven by organic growth of 5%, while Biopharma Laboratory Services revenue grew approximately 3% and driven by strong growth in Central Labs of 9%, partially offset by the expected decline of 11% in early development. We continue to expect early development to show year-over-year growth in the fourth quarter. The trailing 12-month book-to-bill was 1.02. We expect the book-to-bill to grow sequentially quarter-over-quarter in the fourth quarter, but it's overlapping with a very strong fourth quarter last year. Overall, the book-to-bill remains healthy for continued growth.
Adjusted EPS of $3.50 was up 4% year-over-year. Enterprise margins were down 40 basis points due to the impact of Invitae. We expect to finish the year with solid growth across both diagnostics and Biopharma Laboratory Services. Glenn will provide more details on our results in just a moment. We continue to execute well on our strategic priorities by being a partner of choice for health systems and regional local laboratories. By harnessing science and innovation to expand our leadership in important therapeutic areas. And by utilizing data and technology to bring important services and capabilities to our customers. In the third quarter, Labcorp continued to advance in these strategic growth areas. First, we maintained a leadership position as a partner of choice for health systems. During the third quarter, we announced an agreement to acquire select operating assets of Ballad Health outreach lab services.
Ballad Health expands our comprehensive laboratory and testing capabilities, to rural communities in Tennessee, Virginia, North Carolina and Kentucky. We also entered into a strategic collaboration with Naples Comprehensive Healthcare in Southwest Florida to manage the daily operations of its inpatient laboratory operations. Turning to regional and local laboratories. We signed a new agreement to acquire select assets of Lab Works, an independent clinical laboratory located in Alabama. And we closed the previously announced acquisition of select assets of BioReference's Health Laboratory testing business. We continue to have a strong business development pipeline, and we look forward to sharing more of those details in the future. We also made several notable advances in science, technology and innovation in the quarter through strategic acquisitions, investments and new product launches.
First, we completed the acquisition of select assets of Invitae during the quarter. Performance was in line with our expectations, and we continue to expect it to be slightly accretive to earnings for 2025, with top line growth of approximately 10%. We are excited about Invitae's complementary cutting edge science, their genetic testing solutions and technology, which aligns strategically with Labcorp's focus on specialty medicine and oncology. The acquisition extends our leadership in specialty testing capabilities and our ability to utilize genetic data to improve clinical trials and treatment regimens in oncology and select rare diseases. By integrating Invitae's genetic testing technology with Labcorp's specialty testing capabilities, we can offer a more complete set of insights for each patient from testing to diagnosis to treatment.
The integration is on track with our financial goals without impacting the great science and customer experience that Invitae provides today. In July, we announced an expanded collaboration with Ultima Genomics, to utilize its sequencing solution and technology to explore new whole genome sequencing clinical applications. including MRD in patients with early-stage solid tumor cancers. In August, Labcorp received De Novo marketing authorization from the FDA for our PGDx elio plasma focus Dx, the industry's only kitted pan solid tumor liquid biopsy test. This test enables laboratory to perform genomic profiling when tissue is limited or unavailable. Labcorp has an industry-leading comprehensive oncology testing menu, and we are uniquely positioned as the only company offering FDA-authorized kitted solutions for both tissue and liquid-based solid tumor testing.
We also continue to expand our Labcorp OnDemand offerings with additional consumer initiated tests in July and August, including Syphilis and Luteinizing Hormone tests. Subsequent to the quarter end, we announced an exclusive agreement with NowDiagnostics to distribute the first over-the-counter point-of-care Syphilis blood test granted marketing authorization by the FDA. We plan to make the test available to providers by the end of 2024, and directly to patients to Labcorp OnDemand in 2025. In the quarter, we also made improvements to our customer experience, using data and technology to bring important services and capabilities to our customers. We introduced a new order tracking experience to our diagnostic customers, giving the majority of providers real-time visibility of test order status.
This new capability offers comprehensive sample tracking enhancing providers' ability to manage patient care effectively with clear up-to-date information on all test orders. Ovia Health by Labcorp announced the expansion of its women health solutions to include a personalized, comprehensive postpartum experience. This 12-month program is designed to help women manage multiple aspects of the postpartum period through personalized recovery mode, symptom tracking and alerts and mental health support. I am proud of our accomplishments and how we operate as an organization. We recently earned Ethisphere Compliance Leader Verification which recognizes organizations with an outstanding commitment to achieving a best-in-class ethics and compliance program. Ethics and integrity are at the heart of everything we do, and integral to our mission to improve health and improve lives.
We were also proud to be named a Best Place to Work for Disability Inclusion after earning the top score of 100 by the 2024 Disability Equality Index. In the quarter, Commerce delayed the implementation of PAMA, removing a potential $80 million revenue headwind in 2025. While we are pleased with this further delay, we continue to work closely with our trade associations to seek a permanent fixed of PAMA as there is bipartisan recognition that long-term reform is needed. In conclusion, we continue to execute well on our short-term financial commitments while also making progress on our longer-term strategy. I am confident in our growth opportunities, and we remain on track to achieve our long-term outlook.
With that, I'll turn the call over to Glenn.
