Monolithic Power Systems (MPWR) is down about 3.7% in Friday trading (May 1, 2026) as the market digests the company’s first-quarter earnings release from after the close on April 30 and the forward outlook that came with it. Despite strong reported growth, the stock is seeing a typical post-results reset, with investors focusing on the path for margins and the sustainability of the recent surge in data-center-related demand.

MPS reported Q1 2026 revenue of $804.2 million (+26.1% year over year) and GAAP diluted EPS of $3.92 (non-GAAP diluted EPS of $5.10). For Q2 2026, the company guided revenue to $890 million–$910 million and GAAP gross margin to 55.1%–55.7%, which is becoming the new focal point for expectations after the Q1 outperformance.

Management pointed to strength in Enterprise Data, where Q1 2026 revenue was $262.8 million, up 12.6% sequentially and up 97.7% year over year, driven by higher sales of power management solutions for AI and server applications. Communications revenue also improved to $111.5 million, helped by higher sales of power solutions for optical modules and switches, underscoring that the data infrastructure buildout remains a major driver—yet also raising the performance bar that investors now expect each quarter.

Investors will be monitoring whether the Q2 outlook translates into continued operating leverage and stable gross margin around the mid-55% range, especially as product mix shifts toward high-growth enterprise data applications. Another key watch item is whether weaker areas cited in the quarter—such as consumer and industrial sequential declines—stabilize enough to keep overall growth resilient if data-center demand normalizes.
