Simply Wall St · 2d ago

Renesas Electronics (TSE:6723) has pushed deeper into gallium nitride technology by introducing its first 100V low-voltage GaN power transistors aimed at AI data centers, robotics and other high power density systems.

For investors tracking Renesas Electronics, the new GaN launches come after a sharp run. The share price has delivered a 69.48% year to date gain and a 110.73% total shareholder return over one year, even though the stock has fallen 20.81% over the past 90 days.

Scan how Renesas Electronics fits into the AI hardware story by comparing it with our hand picked 91 AI infrastructure stocks that are also building the power backbone for data hungry workloads.

After a surge on AI optimism and a pullback over the past quarter, Renesas Electronics now forces a choice: Is this the moment to step in, or does patience for a lower entry make more sense?

Most Popular Narrative: 27.3% Undervalued

Renesas Electronics last closed at ¥3,771, while the most followed narrative sets fair value closer to ¥5,188. That gap frames the entire AI and power semiconductor story investors are weighing today.

The re-shoring of semiconductor manufacturing and emphasis on supply chain resiliency, combined with Renesas' efforts to optimize its factory footprint and build inventory buffers, may lead to improved order visibility and reduced supply chain risk, supporting more resilient revenues and earnings in the medium to long term.

Result: Fair Value of ¥5,188 (UNDERVALUED)

Still, the Renesas Electronics story carries real pressure points, including slower uptake of key automotive chips and ongoing trade and tariff uncertainty that could hit demand and costs.
