Listen to the news

Resonac Holdings (TSE:4004) is back in focus after Matlantis Inc. detailed a joint program that uses AI to let experimental chemists at Resonac run atomistic simulations without coding.

Resonac Holdings has seen mixed momentum recently, with the share price up 2.47% on the day to ¥13,895 but down 13.48% over 30 days and 28.10% over 90 days, while the 1-year total shareholder return of 174.62% and the very large 3-year total shareholder return suggest longer term backing for the story despite recent weakness.

Resonac Holdings now trades at a steep discount to both analyst targets and intrinsic estimates after a sharp pullback. Is that a valuation gap that closes, or a warning that the market’s caution has a point?

Most Popular Narrative: 50% Undervalued

Resonac Holdings closed at ¥13,895 against a widely followed fair value estimate of ¥28,000. This frames the current pullback as a sizeable valuation gap rather than just noise in the chart.

The global push toward electrification and renewable energy is catalyzing surging long-term demand for compound semiconductors and high-performance graphite products. These are markets where Resonac's technological leadership enables both higher volumes and premium pricing, directly supporting sustained revenue and margin growth. Demographic changes and heightened healthcare demand are not just moderate growth drivers. Resonac's advanced materials are integral to next-generation medical devices and pharmaceuticals, positioning the company as a key supplier in high-growth healthcare verticals that can generate a significant and stable earnings stream.

See why 2 investors see Resonac Holdings as 50% undervalued.

Result: Fair Value of ¥28,000 (UNDERVALUED)

Still, the bull case around Resonac Holdings can unravel if cost inflation and currency swings persist, or if the Chemicals segment drags longer than expected.

Another Take On Resonac Holdings’ Valuation

On earnings-based multiples, Resonac Holdings looks rich. The current P/E of 45.6x sits well above the JP Chemicals industry at 12.9x and the peer average of 20.3x. It also exceeds a fair ratio of 28.7x, which points to valuation risk if sentiment cools.

So investors weighing the 50% undervalued narrative need to ask whether the premium multiple is a sign of justified confidence, or whether the margin of safety has already been spent.
