TimesSquare Capital Management U.S. Focus Growth Strategy stated the following regarding Monolithic Power Systems, Inc. (NASDAQ:MPWR) in its Q4 2024 investor letter:
“Monolithic Power Systems, Inc. (NASDAQ:MPWR) designs and develops integrated semiconductor solutions for power delivery architectures in computing, storage, automotive, industrial, communications, and consumer applications. Their stock came under pressure during the quarter due to a research report alleging technical issues with Monolithic’s products on Nvidia’s Blackwell AI platform and that it was in danger of completely losing that business. Our research indicated there is little merit to this claim and while Nvidia is going to multi-source, it is unlikely that Monolithic will be fully displaced. That gave us an opportunity to add this stock to the portfolio.”
