Financial Performance and Operational Strength

Labcorp delivered a strong financial performance in the third quarter of 2025, reflecting the effectiveness of its strategic initiatives. Consolidated revenues for Q3 2025 reached $3,563.50 million, an 8.6% increase over Q3 2024. Year-to-date, revenues for the nine months ended September 30, 2025, grew 7.8% to $10,435.90 million. This growth was underpinned by a healthy mix of organic expansion (6.2% in Q3 2025) and strategic acquisitions (1.7% in Q3 2025).

The Diagnostics Laboratories (Dx) segment was a significant driver, with Q3 2025 revenues increasing 8.5% to $2,769.60 million. This was fueled by 6.3% organic revenue growth and a 4.7% increase in total volume, with organic volume contributing 3.5%. The Dx segment's operating margin improved by a notable 110 basis points year-over-year to 16.3% in Q3 2025, primarily due to strong organic demand and the accretive performance of Invitae . Invitae (NVTA), acquired in 2024, was accretive in Q3 2025 and is expected to be slightly accretive for the full year 2025, with revenue growth exceeding 10%.

The Biopharma Laboratory Services (BLS) segment also contributed positively, with Q3 2025 revenues growing 8.3% to $799.10 million. This included 5.3% organic growth and a 3% favorable impact from foreign currency translation. Central Laboratories demonstrated strong performance, with 10% revenue growth (7% constant currency) in Q3 2025, more than offsetting softness in Early Development. The BLS segment's operating margin improved 20 basis points year-over-year to 16.5% in Q3 2025, driven by increased organic demand. The segment ended the quarter with a robust backlog of $8.6 billion, with approximately $2.7 billion expected to convert into revenue over the next 12 months, and a trailing 12-month book-to-bill ratio of 1.09.

Operational efficiencies, particularly from the LaunchPad initiative, continue to be a key factor in margin expansion, offsetting typical increases in personnel costs. Cost of revenues as a percentage of revenue decreased to 71.2% in Q3 2025 from 72.4% in Q3 2024, reflecting these efficiencies and revenue growth. Selling, general, and administrative expenses also decreased as a percentage of revenues due to revenue growth and reduced costs from the Fortrea (FTRE) spin-off.

Liquidity and Capital Allocation

Labcorp maintains a strong liquidity position and a disciplined capital allocation strategy. For the nine months ended September 30, 2025, net cash provided by operating activities increased by $217.70 million to $1,026.30 million, primarily due to higher earnings. The company's debt leverage stood at 2.4x gross debt to trailing 12-month adjusted EBITDA as of Q3 2025, slightly below its targeted range of 2.5x to 3x, indicating ample financial flexibility.

Capital expenditures for the nine months ended September 30, 2025, were 3% of revenues, primarily directed towards supporting core business growth, facility expansion, and acquisition integration. Labcorp actively uses its free cash flow for strategic acquisitions, share repurchases, and dividends. The company has an outstanding authorization to purchase up to $1,055.40 million of common stock. The accounts receivable securitization facility was expanded in January 2025, increasing borrowing capacity from $300 million to $700 million. Management is confident in its ability to meet short-term and long-term cash needs, supported by strong operating cash flows and available credit facilities.

Outlook, Guidance, and Risks

Labcorp's management has provided a confident outlook for 2025, reflecting the company's strong performance and strategic momentum. The updated 2025 enterprise revenue growth guidance is set at 7.4% to 8.0%, with the midpoint lowered by 40 basis points primarily due to currency fluctuations and acquisition timing. Adjusted EPS guidance for 2025 is $16.15 to $16.50, representing an implied growth rate of 12% at the midpoint, an increase of $0.05 from prior guidance. Free cash flow is projected to be between $1.165 billion and $1.285 billion, with the midpoint raised by $25 million.

Segment-specific guidance includes Dx revenue growth of 7.2% to 7.8%, assuming approximately 4.5% organic revenue growth. BLS revenue is expected to grow 5.7% to 7.1%, with Central Labs growing in the mid-single digits and Early Development in the low single digits for the full year. Enterprise margins are expected to increase, with improvements in both Dx and BLS segments in 2025 versus 2024, driven by top-line growth and LaunchPad savings.

Despite this positive outlook, several risks warrant investor attention. The potential impact of the Protecting Access to Medicare Act (PAMA) remains a concern. Labcorp anticipates a $100 million impact on both top and bottom lines for full year 2026 if PAMA is implemented as currently structured, though efforts are underway to offset approximately $25 million through efficiency initiatives. Legal proceedings, including a significant patent infringement lawsuit with Ravgen (where a jury awarded $272 million in damages, with an appeal filed by Labcorp), and class actions related to data security and ADA compliance, pose potential financial and reputational risks. Foreign currency fluctuations, with approximately 13.5% of revenues denominated in non-U.S. dollar currencies, and interest rate volatility also present ongoing market risks. The timing of study starts in Early Development, particularly for smaller biotechnology companies, is another factor management is closely monitoring.
