About
Danaher Corporation is a Washington, D.C.-based global science and technology company — publicly traded on the New York Stock Exchange (NYSE: DHR) as an S&P 500 Health Care component — developing, manufacturing, and marketing analytical instruments, reagents, consumables, software, and services for life sciences research, clinical diagnostics, and environmental monitoring through approximately 65,000 employees worldwide. In fiscal year 2024, Danaher reported revenues of $23.9 billion (flat year-over-year) with non-GAAP core revenue declining 1% as the biopharma sector's inventory destocking cycle continued, with Q4 2024 revenue of $6.5 billion (+2.0% reported, +1.0% core) representing an inflection toward recovery, generating $6.7 billion in operating cash flow and $5.3 billion in free cash flow. Danaher guided 2025 core revenue growth of approximately 3% — marking the expected return to growth as biopharma customers who destocked pandemic-era bioprocessing supply surpluses return to normalized purchasing. CEO Rainer Blair leads Danaher's post-spinoff strategy: in September 2023, Danaher separated its Environmental & Applied Solutions segment as Veralto Corporation (NYSE: VLTO), creating two independent public companies — Danaher (pure-play life sciences and diagnostics) and Veralto (water quality and product identification). Danaher's current portfolio centers on bioprocessing (Cytiva's bioreactors, membranes, single-use manufacturing for drug production), clinical diagnostics (Beckman Coulter chemistry and hematology analyzers, Radiometer blood gas analyzers, Cepheid molecular diagnostics), and life sciences research instruments (SCIEX mass spectrometry, Leica Microsystems microscopy).
