Danaher Masimo Deal: Will It Close in 2026?
The Danaher Masimo deal could mark one of the most significant healthcare transactions of 2026.
According to reporting, Danaher is closing in on a nearly $10 billion acquisition of Masimo, a pulse oximeter and patient-monitoring technology company. If announced and completed, the deal would represent Danaher’s first major acquisition since its $5.7 billion purchase of Abcam in 2023.
The key question investors are asking:
Will regulators approve the Danaher Masimo deal — and what are the real risks to closing?
Here is my fully objective analysis.
Danaher Masimo Deal: Transaction Overview and Valuation
Let’s start with the hard numbers.
-
Implied deal size: ~$10 billion
-
Danaher market capitalization: Over $150 billion
-
Masimo market capitalization: ~$7 billion
-
Masimo stock performance: Down more than 57% since its November 2021 peak
-
Prior Danaher acquisition: Abcam for $5.7 billion (2023)
Masimo has recently faced corporate turbulence, including:
-
A $1 billion acquisition of Sound United (2022)
-
A subsequent proxy fight with activist Politan Capital
-
The ouster of founder Joe Kiani as CEO in 2024
-
Sale of Sound United to Samsung’s Harman for $350 million
Additionally, Masimo recently secured a $634 million federal jury award against Apple for patent infringement related to blood-oxygen monitoring technology.
From a valuation perspective, a ~$10 billion price implies a significant premium to Masimo’s current market capitalization — but also reflects the strategic value of proprietary monitoring technology.
Strategic Rationale Behind the Danaher Masimo Deal
Danaher operates primarily as a life sciences and diagnostics tools platform, providing instruments and technologies used in drug development and manufacturing.
Masimo operates in patient-monitoring hardware, especially pulse oximetry.
This means the Danaher Masimo deal is largely:
-
Adjacent expansion, not horizontal consolidation
-
A move into clinical monitoring markets
-
A step deeper into hospital-facing product lines
Danaher’s historical strategy has been to acquire, integrate, optimize margins, and expand distribution globally. The Masimo platform fits that playbook.
Strategically, the acquisition would:
-
Expand Danaher’s presence in hospital systems
-
Diversify revenue into monitoring hardware
-
Leverage Danaher’s operational discipline to improve margins
-
Add IP-backed medical device revenue
This is not a “roll-up of direct competitors.” It is a portfolio expansion.
That distinction matters enormously for regulatory review.
Regulatory Review of the Danaher Masimo Deal
From a competition standpoint, this transaction appears structurally cleaner than most mega-mergers.
1. Horizontal Overlap Is Minimal
Danaher is not a dominant pulse oximeter manufacturer.
Masimo is not a dominant life sciences drug-manufacturing tools provider.
There is no obvious market-share combination that materially reduces competitors in a defined product market.
2. Vertical Concerns Are Limited
The most plausible regulatory question is whether Danaher could:
-
Bundle Masimo devices with other diagnostic platforms
-
Gain leverage over hospital purchasing contracts
-
Foreclose rival monitoring-device makers
However:
-
Hospitals typically negotiate multi-vendor contracts.
-
Medical device markets remain competitive.
-
Danaher is not vertically integrated in a way that obviously excludes rivals.
3. Precedent Matters
Healthcare tools and device M&A has historically cleared unless:
-
It eliminates a direct top competitor
-
It creates extreme device market concentration
-
It triggers reimbursement distortions
None of those are clearly evident here from public information.
Risks That Could Derail the Danaher Masimo Deal
While approval appears likely, risk is never zero.
1. Patent Litigation Spillover
Masimo’s legal battles with Apple over blood-oxygen monitoring technology highlight that IP disputes remain active in this category.
If regulators perceive:
-
Technology foreclosure risk
-
Or device ecosystem exclusion concerns
Review timelines could extend.
2. Activist and Governance Overhang
Masimo’s recent governance turmoil — including the removal of its founder — may introduce shareholder negotiation dynamics.
But this is not an antitrust barrier. It’s an execution variable.
3. Political Healthcare Climate
Healthcare device pricing can become politically sensitive. If the acquisition is framed as increasing hospital costs, it could attract scrutiny — though structurally this is not a pricing-consolidation deal.
Financial Context of the Danaher Masimo Deal
Danaher’s balance sheet capacity is substantial given:
-
Market cap exceeding $150 billion
-
History of disciplined M&A integration
-
Successful prior integration of Abcam
A $10 billion deal is meaningful but not transformative relative to Danaher’s size.
For Masimo:
-
Shares have declined 57% from peak
-
The business has endured strategic missteps
-
The Apple litigation win provides IP value validation
This is the type of scenario where a larger operator extracts operational upside from a stressed asset.
My Final Call on the Danaher Masimo Deal Approval
Objectively, this deal appears far less antitrust-sensitive than large horizontal healthcare mergers.
There is:
-
No obvious competitor elimination
-
No immediate market concentration spike
-
No monopoly creation scenario
-
No systemic reimbursement distortion
Therefore:
My base case: the Danaher Masimo deal is highly likely to receive regulatory approval.
My estimated probability:
-
Approval: ~80–90%
-
Approval with light review conditions: possible but minor
-
Block: low probability absent new information
Compared to shipping consolidation or health insurer mergers, this transaction is structurally straightforward.
Unless hidden overlaps emerge during formal review, approval is the more probable outcome.
