Masimo Corporation (MASI) How It Makes Money

Masimo Corporation generates the vast majority of its revenue from its core Healthcare segment, operating on a classic razor-and-blade business model where the initial sale of monitoring devices (the razor) drives a continuous stream of high-margin, proprietary sensor and software sales (the blades). This structure creates a highly defensible, recurring revenue base for the company.

Masimo Corporation's Revenue Breakdown

As of the third quarter of 2025, the company's revenue is nearly all from its continuing operations-the Healthcare segment-following the strategic divestiture of the non-healthcare consumer audio business. The financial engine of the continuing business relies heavily on the recurring sales of single-use sensors and long-term service agreements.

Here's the quick math for Q3 2025: Consumable and Service revenue was roughly $316 million, while Capital Equipment and Other revenue was about $55 million, out of a non-GAAP total of $371 million. While capital equipment saw a huge jump-67% growth-this often reflects lumpiness in hospital purchasing cycles, so you defintely want to watch the long-term trend.

Business Economics

The core economic engine is the consumable revenue stream, which is highly prized by analysts because it is recurring and boasts superior margins. This is the real value driver.

• Razor-and-Blade Leverage: The initial sale of a Masimo SET® pulse oximetry or other advanced monitoring instrument (the capital equipment) essentially locks in a customer for years of consumable purchases, like single-patient-use sensors. The capital equipment is the market-share land-grab.
• High-Margin Consumables: Consumable and service revenue is the lifeblood, providing the high-margin, predictable cash flow. Historically, the long-term growth rate for consumables has been in the double-digits on a multi-year compounded annual growth rate (CAGR) basis, which is a strong sign of business health.
• Pricing Strategy: The company's pricing model is built around intellectual property (IP) protection, which allows it to command a premium for its proprietary measurements like Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry. This technology is considered a standard of care in many top-tier US hospitals.
• Strategic Expansion: Masimo is actively expanding its footprint by leveraging its existing sales force to push into adjacent advanced monitoring categories like Capnography, Hemodynamics, and Brain Monitoring, targeting a growth rate of 10% to 20% in these markets.

Masimo Corporation's Financial Performance

Looking at the full fiscal year 2025 guidance provides a clearer picture of the business's profitability and scale, focusing only on the continuing Healthcare operations.

• Revenue Scale: Full-year 2025 non-GAAP revenue for continuing operations is projected to be between $1.51 billion and $1.53 billion, reflecting solid constant currency growth of 8.5% to 10.0%.
• Profitability Margins: The trailing twelve months (TTM) Gross Margin sits at approximately 52.77%, indicating that the cost of goods sold is well-managed, likely due to the high-margin nature of the consumable products.
• Operating Efficiency: The non-GAAP Operating Margin for the full year 2025 is guided to be in the range of 27.3% to 27.7% (including the impact of new tariffs), which is a strong margin for a medical technology company.
• Earnings Outlook: Non-GAAP Earnings Per Share (EPS) for the full fiscal year 2025 is projected between $5.40 and $5.55. What this estimate hides is the significant one-time impact from the discontinued consumer audio business, which led to a negative GAAP Net Margin of -24.85% on a TTM basis.

The core healthcare business is growing and highly profitable at the operating level, but the recent divestiture costs weigh heavily on the reported GAAP net income. For a deeper dive, check out Breaking Down Masimo Corporation (MASI) Financial Health: Key Insights for Investors.
