The deal adds pulse oximetry and patient monitoring technology to Danaher’s diagnostics portfolio.
RT’s Three Key Takeaways:
- Acquisition Finalized: Danaher Corporation has completed its purchase of Masimo Corporation, a provider of pulse oximetry and patient monitoring solutions for acute care settings.
- Operational Continuity: Masimo will function as a stand-alone operating company under its existing brand within Danaher’s diagnostics segment, following the removal of its stock from the Nasdaq Stock Market.
- Clinical Capabilities: The merger combines Masimo’s sensor technology and artificial intelligence (AI) with Danaher’s portfolio to address clinical challenges in the healthcare industry.
Danaher Corp completed the acquisition of Masimo Corp, a provider of specialty diagnostics including pulse oximetry and patient monitoring solutions that primarily serves acute care treatment settings.
The $9.9 billion deal to acquire Masimo was announced in February 2026.
As a result of the transaction, Masimo is now a wholly-owned subsidiary of Danaher. Masimo common stock has ceased trading on the Nasdaq Stock Market, though the company will continue to operate under the Masimo brand as a stand-alone entity within Danaher’s diagnostics segment.
“Masimo is a strong strategic fit for Danaher. Together, we expect to strengthen our ability to deliver differentiated products in acute care settings and accelerate Masimo’s growth and global reach,” said Julie Sawyer Montgomery, executive vice president of diagnostics at Danaher, in a news release.
Danaher reported that Masimo’s sensor technology and AI-enabled patient monitoring provide new capabilities to its existing diagnostics portfolio. The company stated it works with customers to solve clinical challenges and move innovations from discovery to delivery for patients.
Regarding financial outlook, Danaher maintained its previously communicated second quarter and full-year 2026 guidance, excluding Masimo’s contribution. The company expects to update its full-year 2026 guidance during its second quarter earnings release to incorporate the expected impact from Masimo.
The consideration payable to former Masimo stockholders will be paid according to the terms of the merger agreement, as described in materials filed with the US Securities and Exchange Commission (SEC).
