Danaher Acquires Masimo for $9.9B, Expanding Into Patient-Monitoring and Acute Care

One of the largest medtech buyouts of 2026: Danaher pays a 38% premium to absorb the pulse oximetry pioneer — and its contested consumer electronics baggage — accelerating its pivot back to pure-play diagnostics.

THE PARTIES

 

ACQUIRER

Danaher Corporation (NYSE: DHR)

Washington D.C.-based global science and technology innovator with ~$22B in annual revenues. Operates through three segments: Biotechnology, Life Sciences, and Diagnostics. Known for its proprietary Danaher Business System (DBS) lean operating model and a long track record of value-creating acquisitions.

TARGET

Masimo Corporation (Nasdaq: MASI)

Irvine, CA-based medical technology company, inventor of the modern pulse oximeter and Signal Extraction Technology (SET). Generates ~$2.2B in annual revenues from hospital patient-monitoring, non-invasive vital signs measurement, and — controversially — a consumer health wearables division (Masimo Consumer, formerly Sound United) acquired in 2022.

 

DEAL OVERVIEW

Danaher is paying $180 per share in cash for all outstanding shares of Masimo — a 38.3% premium to the stock's last close before announcement. The total enterprise value, including assumed debt and net of acquired cash, stands at approximately $9.9 billion. Under the merger agreement, a Danaher subsidiary will first launch a tender offer; once completed, the remaining shares are acquired through a second-step merger.

The deal brings Masimo's market-leading pulse oximetry technology into Danaher's Diagnostics segment, which currently includes Radiometer and Beckman Coulter. Following completion, Masimo is expected to operate as a standalone business within Danaher's Diagnostics segment, expanding its portfolio into patient-monitoring and adjacent acute-care technologies.

 

"We've followed this innovative company for many years and see it as an exceptional strategic fit for Danaher."

— Rainer M. Blair, President & CEO, Danaher

STRATEGIC RATIONALE

Masimo solves a gap in Danaher's Diagnostics portfolio: the ability to monitor patients continuously at the bedside, not just in labs. Hospitals increasingly want end-to-end solutions from a single vendor, and Masimo's non-invasive monitoring technology is deployed across more than 200 countries. By acquiring Masimo, Danaher adds a highly recurring, high-margin consumables stream (rainbow sensors) alongside its existing reagent-based businesses.

Importantly, Danaher indicated it plans to exit the consumer health business that Masimo's prior management acquired — removing a persistent valuation discount that had weighed on Masimo's stock since 2022. Danaher expects the transaction to be accretive to adjusted earnings in the first full year of ownership and will realize more than $125 million in annual cost synergies and more than $50 million in annual revenue synergies by year five.

The deal is valued at approximately 18x estimated 2027 EBITDA, or 15x including full synergies — broadly in line with premium medtech multiples.
