Active R&D pipeline of 30 device programs spanning pulse oximetry, CO-oximetry, and non-invasive monitoring, signaling continued investment in innovation despite modest 10% R&D intensity.

Market-leading position in non-invasive patient monitoring with flagship products (Masimo SET®, Masimo W1®) deployed across hospital and perioperative settings globally.

Watch Out For

Significant revenue contraction YoY: FY 2025 revenue dropped to $1.3B from $2.0B (−35%), with R&D spend falling from $191M to $131M, signaling potential strategic reorientation or headcount pressure.
Only 1 active job opening listed despite 5,000–10,000 employee base suggests frozen or highly selective hiring; device-focused pipeline may limit career optionality for small-molecule or biologics-trained professionals.
