Over the past six months (April 2026 - October 2026), Monolithic Power Systems' stock was up 51.8% over the past year and 58.1% year-to-date as of October 7, 2026. In Q1 2026 (May 2026), the company reported record quarterly revenue of $804.2 million, a 26.1% year-over-year increase, with net income surging 43.1% to $193 million, primarily driven by AI-driven demand in the enterprise data segment, and management raised the quarterly dividend by 28% to $2.00 per share. Q2 2026 (August 2026) revenue reached approximately $980.6 million, up 48% year-over-year, largely due to enterprise data and communications demand related to AI and server workloads. In September 2026, MPS entered a long-term agreement with GlobalFoundries to expand manufacturing capacity at its 300 mm facility in Singapore, expected to ramp up by early 2027, for power management products in automotive, industrial robotics, and AI/cloud infrastructure. The stock saw a jump in early October 2026, attributed to a broader rebound in semiconductor shares as investors rotated back into AI-linked chip names, alongside continued optimism regarding MPWR's manufacturing expansion plans and its exposure to AI and communications markets. Monolithic Power Systems is scheduled to report its Third Quarter 2026 results on October 29, 2026. Despite strong performance, the stock has been noted as potentially overvalued by some metrics, with a P/E ratio significantly above its historical median, and insider activity has shown a significant sell-off, with insiders selling $746.3 million worth of shares over the past 12 months and no buying activity recorded.
