Intuitive Surgical, Inc. (ISRG) Income Statement

The revenue trajectory shows a clear upward trend, with growth rates climbing from the low teens to the high teens over the past two years. This acceleration appears driven by both procedure volume expansion and system placements, as the company's installed base continues to grow. The durability of this growth is supported by the recurring nature of instruments and accessories revenue, which typically scales with procedure volumes.

Gross margins have been remarkably stable, fluctuating within a narrow band of 64.7% to 68.3%, which suggests that the company has been able to maintain pricing power and control input costs. This stability is notable given the company's rapid growth and investments in manufacturing capacity. The slight dip in 2025Q1 to 64.7% may reflect product mix or one-time costs, but the subsequent recovery to 67.8% indicates that these pressures were transient.

Operating income has scaled disproportionately relative to revenue, with operating margin improving by nearly 900 basis points over the period. This suggests that the company's cost structure is becoming more efficient as it grows, with SG&A and R&D expenses growing at a slower pace than revenue. The leverage is particularly evident in 2026Q2, where operating income grew 30.8% year-over-year on 18.5% revenue growth, highlighting the scalability of the business model.

The combined R&D and SG&A ratio has decreased steadily, reflecting operating leverage and cost control. R&D spending has grown in absolute terms but at a slower pace than revenue, suggesting that the company is achieving economies of scale in its innovation efforts. SG&A has also been managed tightly, with the 2025Q4 spike to $687.1M possibly due to seasonal selling costs, but the overall trend is downward, which supports margin expansion.

The most significant operational inflection appears to be in 2025Q2, where operating margin crossed the 30% threshold for the first time in the data series. This was driven by a combination of accelerating revenue growth and disciplined expense management. The subsequent quarters have maintained this higher margin level, suggesting that the company has achieved a structural improvement in its cost structure, possibly due to scale benefits and product mix shifts.
