Renesas (TSE:6723) Valuation Check After Launching New Wi‑Fi 6 Wireless Microcontrollers for IoT Growth

Renesas Electronics (TSE:6723) just rolled out its first Wi-Fi 6 microcontrollers, the RA6W1 and RA6W2, aiming squarely at always connected, low power IoT gear across smart homes, factories and healthcare.

See our latest analysis for Renesas Electronics.

The new Wi-Fi 6 MCUs land at a time when Renesas’ 1 month share price return of 18.38 percent and 3 month share price return of 26.66 percent signal strengthening momentum, while its 5 year total shareholder return of 118.19 percent underlines a solid longer term record.

If this kind of connected device story interests you, it is also worth exploring other opportunities in high growth tech and AI stocks that may be riding similar digital transformation trends.

With shares up strongly over the past quarter but still trading at a modest discount to analyst targets and intrinsic value estimates, is Renesas quietly undervalued today, or is the market already pricing in its next wave of growth?

Most Popular Narrative: 9.4% Undervalued

With Renesas Electronics last closing at ¥2190 against a narrative fair value near ¥2417, the storyline leans toward upside driven by ambitious growth and margin recovery.

The increasing adoption of electric vehicles and autonomous driving features is set to drive higher demand for advanced automotive MCUs and ADAS SoCs, particularly as Renesas ramps production of its new 28 nm MCU platform beyond China into Japan and Europe, this is likely to meaningfully support automotive segment revenue growth and help Renesas outpace the addressable market over the next 2 to 3 years.

Another View: Rich Sales Multiple, Room To Normalize

While the narrative fair value points to upside, the market is already paying 3.1x sales for Renesas, compared with about 2x for both peers and the wider JP semiconductor space. This is the case even though our fair ratio suggests the stock could justify nearer 7.7x. Is this a safety margin or valuation risk if growth stumbles?
