Net income in Q1 2026 was around $150 million compared with roughly $127 million a year earlier, translating to year over year growth of about 18%. Diluted EPS for the quarter reached approximately $2.95 versus around $2.50 in Q1 2025, implying EPS growth of roughly 18% in line with the top line increase. This consistency between revenue and EPS growth reflects a steady cost structure and a business model that converts incremental sales into earnings without significant margin compression.

Guidance and expectations

Management guidance issued for fiscal 2026, as described in recent investor communications, envisages continued double digit revenue growth and stable to slightly improving margins. Monolithic Power Systems has indicated that it expects fiscal 2026 revenue in a range around $2.35 billion to $2.40 billion, which would represent growth of roughly 18% to 20% from the approximate $2.0 billion posted in fiscal 2025.

The company also targets operating margin in the low 30s percentage range for fiscal 2026, consistent with the 2025 level and the Q1 2026 performance. If achieved, this guidance would keep operating income growth broadly aligned with revenue growth and support another year of double digit EPS expansion. For investors, the guidance matters because it frames expectations for how quickly Monolithic Power Systems can continue to grow in an environment where some semiconductor segments are normalizing after pandemic era demand surges.

Consensus estimates from analysts following Monolithic Power Systems generally reflect confidence in the guidance.
