Summary

Power delivery stays scarce as AI densifies

The growth path is driven by AI racks and electrification making efficient power conversion a binding constraint. Upside requires sustained high-value socket capture and only modest multiple compression.

Analysis

Thesis

As AI racks and electrification become power- and reliability-limited, Monolithic Power can keep winning higher-dollar “power bottleneck” sockets (controllers + integrated modules) and selectively add digitally managed power/telemetry features that defend pricing, sustaining above-peer growth through 2031.

Last Economy Alignment

AI growth converts watts into the binding constraint; MPS sells the efficiency, density, and reliability that unlocks more useful compute and electrification.

Opportunity Outlook

Average Implied 5-Year Multiple

1.9x (from 5 most recent analyses)

Reasoning

MPS is a “picks-and-shovels” beneficiary of AI infrastructure where power conversion, protection, and thermal limits show up early. Versus analog incumbents (TXN/ADI/ON), MPS is more levered to fast-changing AI platform needs and can ship higher-integration solutions with strong gross margins while staying relatively capital-light, supporting a still-premium revenue multiple in 2031.

Risk Assessment

Overall Risk Summary

The main risk is not demand for power, but who captures the economics: standardization, dual-sourcing, or in-house designs could erode socket pricing and compress valuation even with solid execution. Secondary risks are AI capex cyclicality, geopolitics, and the execution complexity of moving from “chips” toward more integrated system solutions.

Trends

Key Changes

In the first week of January 2026, the stock rebounded from a late-December drawdown and posted multiple up days (Jan 2, Jan 5, Jan 6).
No new earnings print in the last 7–10 days; the setup is still dominated by the next quarterly report timing and AI capex sentiment.
Tape action suggests MPWR is still trading as an AI-infrastructure beneficiary with high sensitivity to broader semiconductor risk-on moves.
