Labcorp Holdings Inc. (LH) Stock Price & How to Invest

Labcorp Holdings is a leading US healthcare diagnostics company that runs clinical laboratory tests for physicians, hospitals, health systems, and patients, and also provides laboratory services to pharmaceutical and biotech firms running clinical trials. Its two reporting segments are Labcorp Diagnostics, the routine and specialty testing business that processes millions of patient samples, and Labcorp Biopharma Laboratory Services, which supports drug development with central-lab and early-development testing. Alongside domestic rival Quest Diagnostics, Labcorp is one of the two dominant independent lab networks in the country. The company spun off its clinical-trial contract-research organization, Fortrea, in 2023 to focus on core testing.

The investment picture is that of a defensive, cash-generative healthcare company rather than a high-growth name. Full-year 2025 revenue was about $13.95 billion with net income near $877 million, and management raised 2026 guidance to roughly $14.6 billion to $14.8 billion in revenue and adjusted EPS of about $17.70 to $18.35. Growth comes from mid-single-digit organic testing gains, tuck-in acquisitions of hospital outreach labs, specialty and genomic test menus, and steady biopharma demand, while free cash flow funds a dividend and share buybacks. The trade-off is exposure to reimbursement rates, payer mix, and regulatory pricing that can cap the upside.

Labcorp's biggest risk is reimbursement pressure, since a large share of revenue depends on rates set by Medicare, Medicaid, and commercial payers, and legislated fee cuts under frameworks like PAMA can compress pricing. Payer mix and volume shifts, including the rise of at-home and point-of-care testing, could erode walk-in and routine-test revenue over time. The business is capital and labor intensive, so wage inflation and integration costs from acquisitions can weigh on margins. Biopharma demand is tied to pharma R&D budgets and clinical-trial activity, which can soften in a funding downturn. Regulatory changes around laboratory-developed tests and ongoing competition from Quest Diagnostics and hospital systems add further uncertainty.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Labcorp Holdings Inc.'s investor relations page or your broker.

• Revenue (FY2025): ~$13.95 billion
• Revenue guidance (FY2026): ~$14.6-14.8 billion
• Net income (FY2025): ~$877 million
• Adjusted EPS guidance (FY2026): ~$17.70-18.35
• Market cap: ~$24 billion
• P/E (trailing / forward): ~26x / ~16x

As of July 2026 Labcorp traded near $296 per share for a market cap around $24 billion, close to a 52-week high. The trailing P/E near 26x compresses to roughly 16x on 2026 adjusted EPS guidance, a valuation that sits below many healthcare peers. That reflects steady mid-single-digit revenue growth rather than rapid expansion, plus a modest dividend and buyback program.

There are three common ways to get LH exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so LH sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where LH fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.
