James E. Davis
Chairman, President and Chief Executive Officer at Quest Diagnostics
Thanks, Shawn, and good morning, everyone. In the fourth quarter, we delivered impressive revenue growth of nearly 15%, including approximately 5% organic growth, while also improving our profitability. For the full-year, we drove revenue growth of close to 7%, including approximately 3% organic growth.
In 2024, our team completed eight acquisitions, including Life Labs in Canada and four hospital outreach lab businesses in the US. We also expanded our Advanced diagnostics menu and drove sustained double-digit growth in several clinical areas during the year.
In addition, we attracted new business across the physician, hospital and consumer channels, while also forming new relationships with health plans to extend our geographic reach. Our investments in automation and AI delivered improvements in quality, customer experience and productivity during the quarter and throughout all of 2024, which helped us deliver on our annual 3% Invigorate savings and productivity targets.
We also meaningfully improved employee retention as we strengthened our position as employer of choice. This morning, we provided guidance for 2025 that reflects our confidence in the core strength of our business, continuing robust utilization and the momentum from acquisitions we completed in 2024.
These dynamics position us favorably to accelerate revenue and earnings growth in 2025. Now I'll recap our strategy and discuss highlights from the fourth quarter. Then Sam will provide more detail on our financial results and talk about our financial guidance for 2025.
Our strategy to drive growth is focused on delivering solutions that meet the evolving needs of our core customers, physicians, hospitals and consumers. We enable growth across our customer channels through advanced diagnostics with an intense focus on faster-growing clinical areas, including brain health, advanced cardiometabolic and molecular genomics and oncology.
In addition, acquisitions are a key growth driver with an emphasis on accretive outreach purchases as well as other independent labs. Our strategy also includes driving operational improvements across the business with the strategic deployment of automation and AI to improve quality, service, efficiency and the workforce experience.
Here are a few key updates on the progress we have made in these areas in the fourth quarter of 2024. Please note that my following comments are focused primarily on our US operations. In Physician Lab Services, we delivered high single-digit revenue growth, driven primarily by strong organic growth and contributions from acquisitions in the US.
As a reminder, volumes from both hospital outreach and independent lab acquisitions originate in the physician offices. Last month, we closed our acquisition of the Outreach lab business of University Hospitals in Ohio and completed the transition of the business in January.
We expect to moderate our pace of acquisitions in 2025 as we focus on driving growth from productivity from transactions completed last year. In addition to acquisitions, other growth drivers in the quarter included new customer wins as well as growth among large physician groups and community health centers.
We also saw a step-up in functional medicine testing as more people take an interest in prevention and wellness. In the fourth quarter and full-year, we benefited from robust utilization compared to historical rates. We also continued to see strong volume and revenue growth from Medicare Advantage plans, which value our high-quality, low-cost testing for their narrow networks.
We are well-positioned to benefit from these dynamics as we expand access through our health-plan partnerships with Elevance Health and Centerra Health Plans, both of which took effect on January 1. Today, we have access to more than 90% of the in-network lives in the US.
First, in-hospital lab services, we grew revenues nearly 3% in the fourth quarter, primarily due to solid continued demand for reference testing complemented by growth in professional lab services. Hospitals continued to order a greater range of reference tests from our expanding advanced diagnostics menu rather than performing these tests in their own labs.
By referring testing to us, hospitals are freed from the pressures that come from performing specialized tests in-house such as hiring skilled lab personnel and investing in expensive lab testing equipment. In professional lab services, we completed three collaborations with health systems in Connecticut, New Jersey and Pennsylvania.
We expect to see modest contribution from these relationships in early 2025. Looking at 2025, we expect hospitals to continue to struggle with high wage and supply inflation, constrained access to capital and keeping up-to-date with laboratory innovation.
At the same time, patients and payers want greater value from lab services. Hospitals increasingly recognize that Quest can improve access to innovative and cost-efficient lab services through reference testing, lab management and outreach lab acquisitions.
In consumer initiated testing, our consumer-facing platform, questhealth.com grew total revenues nearly 50% in the fourth quarter and approximately 40% for the full-year to just over $60 million. Together with revenue from our channel partners, consumer initiated testing revenues grew to nearly $100 million in 2024. During the year, we also greatly expanded our Questhealth.com offering to include 135 different tests to provide a comprehensive platform for serving today's increasingly health-minded consumers.
In advanced Diagnostics, we experienced double-digit growth across several clinical areas in the fourth quarter, including in brain health, advanced cardiometabolic, autoimmune and women's health. We generated strong growth in brain health, health largely due to impressive demand for our AD blood tests for assessing Alzheimer's disease risk.
We will continue to explore opportunities to extend our portfolio with new biomarkers that can help providers better assess Alzheimer's and other forms of dementia. We also generated strong growth in areas of advanced cardiometabolic and autoimmune testing, and we expect these patterns to continue in 2025. Our growth in women's health was driven largely by prenatal and hereditary genetic testing.
We were also pleased to see strong adoption of our self-collection option for testing of genital tract infections during the quarter. In molecular genomics and oncology, we spent much of last year developing and validating our Haystack MRD blood test to aid in the early detection of minimal residual disease from solid tumor cancers.
We also engaged with approximately 75 leading academic health systems and community oncology centers in our Haystack MRD early Experience program and are pleased with the favorable feedback we received. We are now transitioning these organizations to a commercial program and are focused on expanding utilization among medical oncologists.
Turning to operational excellence, our Invigorate program delivered our targeted 3% annual cost-savings and productivity improvements. Here are some examples of how we're improving operations. We pilot many of our automation and AI solutions at our laboratory in Clifton, New Jersey.
During the fourth quarter, we developed and implemented a proprietary system in that automates labeling and test tube preparation for tuberculosis testing, eliminating manual intervention and improving quality. In addition, we began testing and automated a sessioning solution that speeds requisition processing.
Also in Clifton, we deployed a third-party AI solution that enhances parasiteology screening by flagging likely positive specimens requiring closer human examination. We plan to roll-out these solutions to our other labs later in 2025. Improving workforce engagement remains a major priority, and I'm pleased that our retention rates significantly improved across multiple job categories in 2024.
Now before I turn it over to Sam, I want to thank our more than 55,000 Quest and Life Labs colleagues for delivering on our business imperatives last year. This amazing group of people is the engine behind our growth and the reason we entered 2025 strong, energized and ready to deliver on our purpose, working together to create a healthier world, one life at a time.
And now Sam will provide more details on our performance and 2025 guidance. Sam?
