Shin-Etsu Chemical (TSE:4063) Valuation in Focus After Record-Breaking GaN Substrate Adoption by IMEC

Shin-Etsu Chemical (TSE:4063) has drawn attention after announcing that its QST™ substrate was chosen by IMEC for developing new 300-mm GaN power devices. Early trials achieved a record-breaking voltage threshold, which has spurred interest from major industry players.

See our latest analysis for Shin-Etsu Chemical.

The breakthrough with IMEC has put wind back in Shin-Etsu Chemical’s sails, though the momentum has faced recent headwinds. After starting the year strong, the share price has slipped by 13.7% year-to-date, with a 1-year total shareholder return of -18.5%. However, Shin-Etsu’s three- and five-year total shareholder returns, at 34.7% and 47.8% respectively, show resilience and long-term value potential still embedded in the business as the GaN opportunity develops.

Price-to-Earnings of 16.9x: Is it justified?

Shin-Etsu Chemical trades at a Price-to-Earnings (P/E) ratio of 16.9x, putting it below the peer group average of 19.9x and substantially underneath the estimated “fair” P/E of 21.4x. This suggests the current share price does not fully reflect potential earnings power relative to comparable companies and the level the market could move towards.

The P/E ratio measures how much investors are willing to pay today for a unit of current earnings. It is a widely used indicator in the chemicals sector for evaluating whether a stock appears attractively priced or expensive compared to its peers, factoring in both historical results and forward-looking expectations for profit growth.

With Shin-Etsu’s P/E notably lower than average, the market may be underestimating the company’s capacity for future profit expansion or the positive impact of recent technological breakthroughs. When compared to the industry benchmark of 12.2x, Shin-Etsu does look more expensive than the sector average. This highlights the premium attributed to the quality of its earnings. However, when set against the estimated “fair” P/E of 21.4x, there is a clear case that the stock could see a rerating if its earnings trajectory meets or exceeds expectations. Potential upside lies in closing this gap.
