MPWR and Astera Labs Growth Outstrips Nvidia's 11% YTD Gain
While Nvidia's 11% year-to-date return dominates headlines, secondary infrastructure companies like Monolithic Power Systems and Astera Labs are delivering significantly higher growth, signaling a broadening of the AI investment cycle.
Nvidia remains the world's most valuable publicly traded company, but its 11% year-to-date gain is being eclipsed by lesser-known AI infrastructure stocks. Monolithic Power Systems and Astera Labs have both posted significantly stronger returns this year. Their performance indicates that investors are looking beyond core chipmakers to capitalize on the massive physical build-out required for artificial intelligence computing.
Monolithic Power Systems has rallied more than 40% year to date as data center operators prioritize its power management systems. These components are critical for maintaining continuous server uptime and preventing AI chips from overloading. They operate alongside liquid-cooling infrastructure to manage the extreme heat generated by dense computing clusters. In the first quarter, the company’s total revenue grew 26.1% year over year, with net income rising at a slightly faster rate.
This top-line growth is not evenly distributed. It is heavily concentrated in two specific business segments, highlighting exactly where capital expenditure is flowing. Enterprise data, which supplies power management for AI chips and servers, accounted for roughly a third of total sales and nearly doubled year over year. The communications segment, representing 14% of sales, grew 55.5% year over year and 33.1% sequentially. This segment supplies telecom infrastructure and networking equipment, areas seeing direct benefits from AI tailwinds.
Connectivity demand drives Astera Labs
Astera Labs is capturing a different but equally vital segment of the AI hardware market through rack-scale connectivity solutions. Hyperscalers are increasingly relying on its hardware and software to enable faster data transmission between individual AI chips and broader server clusters. This focus on resolving data bottlenecks has translated into a near-doubling of first-quarter revenue on a year-over-year basis.
The company also posted a 14% sequential revenue increase in the period. In the current AI hardware cycle, double-digit sequential growth is a highly watched metric. A similar trend previously preceded a major share price rally for memory manufacturer Micron. For market participants, the accelerating revenue growth at both Monolithic Power Systems and Astera Labs suggests the AI investment cycle is deepening. Capital is increasingly flowing to the supporting ecosystem of power and connectivity, rather than solely to the primary processors.
