Future Outlook

Masimo has updated its full-year 2025 guidance for continuing operations. Non-GAAP revenue is projected to be between $1,510 and $1,530 million, reflecting 8.5% to 10.0% growth on a constant currency basis.

Industry Context

Masimo's strong performance in its core healthcare business, marked by significant revenue and EPS growth, indicates resilience and effective strategy execution within the medical technology sector. The divestiture of Sound United allows Masimo to sharpen its focus on its high-margin healthcare segment, a trend seen across the industry as companies streamline portfolios to enhance profitability and innovation in specialized areas. The expanded partnership with Philips underscores the importance of strategic alliances in broadening market reach and integrating technologies, a common approach for medical device companies seeking to accelerate growth and innovation. While new tariffs present a headwind, Masimo's proactive mitigation efforts reflect the broader industry's adaptation to evolving global trade policies.

Comparison to Industry Standards

• Masimo's 7.6% non-GAAP constant currency revenue growth in Q3 2025 for its healthcare business is competitive within the medical technology industry, which often sees mid-to-high single-digit growth for established players. For example, companies like Medtronic or Abbott Laboratories typically report similar or slightly lower organic growth rates for their mature segments.
• The 38% non-GAAP EPS growth is exceptionally strong, significantly outpacing many peers in the medical device space, where double-digit EPS growth is considered robust. This suggests strong operational leverage and effective cost management.
• The 450 basis point improvement in non-GAAP operating margin to 27.1% demonstrates superior operational efficiency. This margin level is generally considered healthy for a medical technology company, often exceeding the average for diversified healthcare conglomerates and aligning with more specialized, high-innovation firms.
• The strategic partnership expansion with Philips, a major global healthcare technology company, positions Masimo favorably for broader market penetration and technology integration, similar to how other medical device innovators partner with large distributors or system integrators to scale their solutions globally.

Corporate Governance

Legal Proceedings

• Masimo has been engaged in various legal proceedings against Apple since January 2020, including federal court proceedings, U.S. Patent and Trademark Office (PTO) proceedings, and a U.S. International Trade Commission (ITC) proceeding.
