Power Integrations (POWI) introduced new ultra compact auxiliary power supply reference designs tailored for NVIDIA’s Kyber liquid cooled 800 VDC AI data centers, putting fresh attention on how the stock reflects its AI related power conversion exposure.

The stock has surged in recent months, with a 30 day share price return of 16.66% and a 90 day share price return of 77.77%. The 1 year total shareholder return of 58.59% and 3 year total shareholder return that is down 3.88% suggest strong recent momentum following a more muted longer term picture. Recent AI data center product announcements sit alongside a series of insider share sales in late May, which some investors may see as a check on sentiment, even as the year to date share price return of 127.86% points to rapidly rising expectations around the company’s role in high voltage power conversion for AI infrastructure.

With shares up sharply, trading above the average analyst target and an intrinsic value estimate that sits below the current price, the key question is simple: is Power Integrations now stretched, or is the market just catching up to its AI potential?

Most Popular Narrative: 66.6% Overvalued

At a last close of $84.99 versus a narrative fair value of $51, the most followed view sees Power Integrations priced well ahead of its modeled worth, with that gap resting on some very specific growth and margin expectations.

Ongoing product innovation, especially the integration of digital control and development of disruptive, system-level ICs/modules, enables further market share gains, design wins, and higher-margin business as demand shifts toward energy-efficient solutions in appliances, metering, and industrial automation, positively impacting overall earnings and net margins.

Want to see what kind of revenue runway and margin rebuild need to materialize to bridge a sizeable gap between modelled fair value and today’s price? The core thesis leans heavily on earnings acceleration and a richer profit profile than the recent historical record. Curious how those assumptions stack up over several years and what discount rate is used to bring them back to today’s dollars?

Result: Fair Value of $51 (OVERVALUED)

However, tariffs and trade uncertainty around appliances, along with heavy reliance on consumer demand, could easily upset the growth and margin trajectory embedded in this narrative.
