Rainer M. Blair
President and Chief Executive Officer at Danaher
Well, thank you, John, and good morning, everyone, and we appreciate you joining us on the call today. So we finished the year strong with better-than-anticipated core revenue in all three of our segments and we were particularly encouraged by another quarter of positive momentum in our bioprocessing business and the improving performance in our Life Sciences instruments businesses.
Our team's disciplined execution also drove solid cash-flow and operating profit margin expansion. Now throughout 2024, our 63,000 associates demonstrated an unwavering commitment to leading and executing with the Danaher Business System, which enabled us to successfully navigate a dynamic operating environment. Now their dedication not only drove meaningful process improvements across our businesses, it also delivered impactful innovations for our customers, both of which are positioning Danaher for sustainable long-term success.
Now looking to 2025 and beyond, we believe Danaher is better-positioned than at any point in our 40-year history. The transformation in our portfolio since the beginning of the pandemic has shaped us into a focused life sciences and diagnostics innovator with a re-rated long-term growth, margin and cash-flow profile., our differentiated science and technology portfolio paired with the power of DBS and our talented team positions us well to create long-term shareholder value, while making a meaningful positive impact on human health.
So with that, let's take a closer look at our full-year 2024 financial results. Sales were $23.9 billion and core revenue declined 1.5%. Our adjusted operating profit margin of 28.6% was essentially flat year-over-year and adjusted diluted net earnings per common share were $7.48. We also generated $5.3 billion of free-cash flow, resulting in a free-cash flow to net income conversion ratio of approximately 135%. Strong free-cash flow generation is one of the most important metrics at Danaher and 2024 marks the 33rd consecutive year of free-cash flow to net income conversion, which exceeded 100% and speaks to the differentiated quality of our earnings and business models.
Now through 2024 and into the start of 2025, we deployed approximately $7 billion of capital towards the repurchase of 28 million shares of Danaher common stock. This includes approximately 20 million shares purchased in the second and third quarters and approximately 8 million shares purchased in the 4th-quarter and into January 2025. We also remain active on the M&A front, completing several strategic acquisitions during the year. Now these acquisitions bring innovative technologies and solutions that further strengthen our competitive advantages and position us for sustained long-term success.
Now we also continued to make substantial investments in innovation throughout the year, enabling the launch of several groundbreaking technologies that are advancing our customers' critical work. In biotechnology, Cytiva introduced the CEPIA cell therapy manufacturing platform, which is helping address critical cost and capacity constraints associated with CAR-T cell therapy manufacturing. The efficiencies customers gain through the platform have the potential to increase patient access to these life-saving therapies. In Life Sciences, Beckman Coulter Life Sciences introduced the VT Automated Cell Culture System, which simplifies and accelerates the cell-line development process, enabling pharmaceutical researchers to bring therapies to-market faster.
And in Diagnostics, Beckman Coulter Diagnostics made significant strides in expanding the cardiac and blood virus menus on the DXI 9000, our next-generation high-resolution immunoassay analyzer. With sensitivity 100 times greater than traditional immunoassay systems, the DXI 9000 is enabling faster and more accurate patient diagnoses and ultimately paving the way for precision diagnostics. These are just a few examples of how our innovation engine is driving long-term growth and helping customers solve some of the most important health challenges impacting patients around the world.
So now let's turn to our 4th-quarter 2024 results in more detail. Sales were $6.5 billion in the 4th-quarter and we delivered 1% core revenue growth. Geographically, core revenues in developed markets were essentially flat with a low single-digit decline in North-America and a low-single digit increase in Western Europe. High-growth markets were up low-single digits with solid performance outside of China, more than offsetting a mid-single-digit decline in China. Our gross profit margin for the 4th-quarter increased 50 basis-points year-over-year to 59.5%. Our adjusted operating profit margin of 29.6% was up 90 basis-points, driven primarily by the positive impact of cost-savings initiatives. Adjusted diluted net earnings per common share of $2.14 were up 2.4% year-over-year and we generated $1.5 billion of free-cash flow-in the quarter.
So now let's take a closer look at our results across the portfolio and give you some color on what we're seeing in our end-markets today. Core revenue in our Biotechnology segment increased high-single-digits year-over-year with our bioprocessing business up high-single-digits and our Discovery and Medical businesses up low-double-digits. In bioprocessing, the gradual recovery we saw through the year continued into the 4th-quarter. We were particularly encouraged by the sustained positive momentum in our order book, which grew high-single-digits sequentially. And this represents the sixth consecutive quarter of high single-digit sequential order growth.
Revenue growth in the quarter was primarily driven by consumables, supported by robust demand for commercialized therapies. Equipment demand, while improved, remained subdued as customers continue to be cautious with their capital spending. Now in China, underlying activity levels were relatively stable, but weak as customers faced ongoing challenges in a difficult funding environment. But the continued progress we're making in our business, coupled with healthy underlying market trends reinforces our confidence in the long-term outlook for Cytiva's bioprocessing franchise.
Monoclonal antibodies, which comprise more than 75% of our bioprocessing revenues remain the largest investment area for our customers and 2024 was a near-record year of FDA approvals for new monoclonal antibodies. At the same time, biosimilar development and production are increasing as patents on high-volume therapies expire, making life-saving treatments more accessible and driving broader adoption. With our comprehensive portfolio and an innovation engine focused on increasing yields and enhancing manufacturing efficiencies, we believe we're very well-positioned to support our customers today and for the long-term.
Now turning to our Life Sciences segment. Core revenue increased by 1%. Core revenue in our Life Sciences instrument business was up slightly, exceeding our expectations. In the US and Europe, we saw modest demand improvements at our pharma and applied customers. In China, while we did see a modest benefit from the ongoing stimulus program, market conditions continue to be challenging as customers remain cautious with their investments.
In October, like a Lycom Microsystems expanded its Stellaris confocal microscopy platform with the introduction of, a cutting-edge solution for 3D imaging and spatial biology. Spectraplex enables researchers to gain deeper insights in the cellular organization, interactions and spatial phenotyping, advancing the understanding of disease progression and aiding in the identification of potential therapeutic targets. Now core revenue in our genomics consumables business declined in the quarter. Growth across next-generation sequencing products and basic research was more than offset by declines in proteins, plasmas and gene writing and editing solutions.
Moving to our Diagnostics segment, core revenue decreased 2%. Our Clinical Diagnostics businesses collectively delivered low-single digit core revenue growth. Like a biosystems led the way with nearly 10% growth driven by strength across core histology, advanced staining and digital pathology. Notably, placed a record number of its GT450 digital pathology slide scanners this quarter as clinicians are increasingly looking to leverage its predictive algorithms and productivity gains to deliver more accurate and timely patient diagnoses.
To further enhance the digital pathology capabilities, LICA recently established a strategic partnership with Labs, a global leader in AI-powered digital pathology software. This partnership aims to accelerate the development of next-generation cancer diagnostics by combining LICA Biosystems expertise in instrumentation and extensive global footprint with Lab's leadership in enterprise software and artificial intelligence. Core revenue at Beckman Coulter Diagnostics was essentially flat with mid-single-digit core revenue growth outside of China, offset by the impact of volume-based procurement in China.
Earlier this month, Beckman introduced several cutting-edge research use only assays for neurodegenerative disease research on the DXI 9000. Now these assays allow researchers to detect and quantify emerging neurodegenerative biomarkers with exceptional sensitivity and specificity, providing valuable insights into conditions such as Alzheimer's disease. In addition, the US Food and Drug Administration granted breakthrough Device designation to Beckman's PTAU 217 Beta amyloid 142 assay designed to aid clinicians and identifying patients with Alzheimer's. This designation reflects the potential of Beckman's test to transform how clinicians diagnose and manage Alzheimer's, ultimately leading to improved outcomes for patients and families affected by this devastating disease.
In Molecular Diagnostics, increasing menu adoption and system utilization contributed to another quarter of mid-teens core revenue growth in core non-respiratory reagent portfolio. All of these product lines delivered double-digit growth in the quarter, led by over 20% growth in sexual health as customers are increasingly adopting our multiplex vaginitis panel or MVP. The rapid growth of the MVP panel since its introduction highlights the value rapid turnaround diagnostics brings to women's health clinicians at the point-of-care. The multiplex panel enables physicians to quickly and accurately diagnose infections and prescribe targeted treatments, reducing the need for multiple office visits.
Now beyond enabling improved clinical outcomes, MVP underscores the significant growth opportunities ahead as we continue to expand our women's health business and is also a great example of how is unlocking long-term growth opportunities in outpatient settings. Respiratory revenue of approximately $550 million in the quarter exceeded our expectation of $350 million as we saw both higher volumes and a favorable mix of our 4-in-one test for COVID-19 Flu A, Flu B, and RSV. In 2024, installed-base grew by high-single-digits and is now more than 60,000 instruments globally.
In recent quarters, we've seen healthcare systems and integrated delivery network customers accelerating the placement of new instruments at alternate care sites such as clinics and urgent care centers. This expansion beyond the hospital helps customers improve clinical outcomes and reduce costs by standardizing care across their networks. With the continued expansion of our leading global installed-base, the largest test menu in the market and a robust innovation pipeline is well-positioned for sustained long-term growth.
Now let's briefly look-ahead at expectations for the first-quarter and the full-year 2025. For the full-year 2025, we anticipate core revenue growth of approximately 3%. In addition, we expect an approximately 2% revenue headwind due to recent strengthening of the US dollar. We also expect a full-year adjusted operating profit margin of approximately 28.5%. In the first-quarter, we expect core revenue to decline in the low single-digit percentage range. Additionally, we expect the first-quarter adjusted operating profit margin of approximately 26.5%.
So to wrap-up, we are pleased with our 4th-quarter performance and look-forward to building on this momentum as we move into 2025. Our team successfully executed through a dynamic environment to deliver strong financial results while continuing to invest for the future. Looking ahead, the transformation in our portfolio paired with our organic growth investments has created a lineup of outstanding franchises that are very well-positioned in highly-attractive end-markets. And we're a better, stronger company today, positioned for higher long-term growth, expanded margins and stronger cash-flow with tremendous opportunities to continue building upon this foundation. With the powerful combination of our leading portfolio, talented team and strong balance sheet, all powered by the Danaher Business System, we feel well-positioned to deliver long-term shareholder value for years to come.
So with that, I'll turn the call-back over to John.
