MACOM Stock Rallies on Analyst Upgrade and New 3.2T AI Chipset

Summary
Shares of the semiconductor firm jumped after BMO Capital Markets raised its rating to 'Outperform,' citing attractive valuation. The rally was further fueled by the launch of a new chipset designed for high-speed AI and data center applications.
MACOM Technology Solutions (NASDAQ: MTSI) shares rose more than 4% in morning trading after a dual catalyst of a significant analyst upgrade and a new product announcement for the artificial intelligence infrastructure market.
Analyst Upgrade Cites Compelling Valuation
BMO Capital Markets upgraded MACOM's stock to Outperform from Market Perform, establishing a new price target of $335. Analyst Harsh Kumar, in a note to clients, highlighted that the stock's valuation has become considerably more compelling following a significant pullback from its peak in May.
According to BMO, the company's forward multiples have contracted from the high-50s in June to approximately 29x. The firm also pointed to solid underlying fundamentals in MACOM’s datacenter and industrial/defense segments, with its space business poised to become a meaningful growth driver in the next year.
New 3.2T Chipset Targets AI Infrastructure
AdReinforcing the bullish outlook, MACOM announced the launch of a new front-end chipset for 3.2T optical interconnect applications. This platform is engineered to support the demanding needs of next-generation AI infrastructure, cloud data centers, and high-speed networking.
The solution delivers up to 3.2 terabits per second of throughput and includes new high-performance transimpedance amplifiers and photodiodes. CEO Stephen G. Daly noted the chipset was "engineered and optimized as a platform, helping customers optimize link performance while reducing development and qualification efforts." All components are immediately available.
Market Reaction
The combination of the upgrade and product launch sent shares up 4.2% to $274.19, touching a session high of $275.05. The move comes as the stock has declined from a 52-week high of $418.90, lending credibility to the analyst's valuation thesis. The company's recent strong fiscal Q3 2026 results, which beat Wall Street estimates, provided an additional supportive backdrop for the rally.
