On September 14, Monolithic Power fell 4.7% in regular trading, trading at $1,168.62/share, with turnover of approximately $103 million.

On the news front, the semiconductor sector faced broad-based selling pressure, with NVIDIA down 3.46%, Micron Technology down 7.09%, AMD down 5.95%, Intel down 6.43%, and Broadcom down 3.99%, dragging Monolithic Power lower in tandem. Meanwhile, uncertainty from a Section 337 investigation continued to weigh on sentiment. Vicor Corporation had previously filed a complaint with the U.S. International Trade Commission alleging patent infringement related to certain vertical power delivery systems, naming Monolithic Power and its Chengdu and Shanghai subsidiaries as respondents alongside other firms including Delta Electronics and Luxshare Precision. If the investigation proceeds, it could pose potential risks to market access for the company's related products in the United States.

Notably, Monolithic Power recently signed a long-term manufacturing agreement with GlobalFoundries to deploy its process technology at GlobalFoundries' 300mm facility in Singapore, supporting its mid-to-long-term capacity expansion in power management.
