Tokyo Ohka Kogyo (TSE:4186) Gains From EUV Demand, Is It Fully Priced?

Simply Wall St · 3d ago

Fresh sector forecasts for photoresists and ancillaries have pushed Tokyo Ohka Kogyo (TSE:4186) into focus, as semiconductor manufacturers ramp up EUV lithography for 5G devices, automotive chips, and rapidly expanding demand in China.

Recent trading has been choppy for Tokyo Ohka Kogyo, with the share price down 5.90% over one day and 22.37% over 90 days, even as the year-to-date share price return is 29.93% and the 1-year total shareholder return reaches 57.60%, suggesting that long-term performance remains positive while short-term sentiment has weakened.

After a pullback that leaves Tokyo Ohka Kogyo up strongly over 1 year but weaker over recent months, the question now is whether the current valuation still tilts the risk reward toward new buyers or recent holders.

Preferred P/E of 23.3x: Is it justified for Tokyo Ohka Kogyo?

On earnings multiples, Tokyo Ohka Kogyo trades on a P/E of 23.3x, which leaves the stock looking expensive relative to both its own fair P/E estimate and the wider Japanese chemicals sector.

The P/E ratio compares the current share price with earnings per share and gives you a quick sense of how much investors pay for each unit of profit. For a specialist materials supplier tied to semiconductor demand, this metric often reflects how strongly the market is pricing in both future earnings and the stability of those cash flows.

Here, the gap is wide. Tokyo Ohka Kogyo changes hands at 23.3x earnings, while the estimated fair P/E sits at 19.8x. The stock also trades at a higher multiple than the JP Chemicals industry at 12.7x and above the 16.7x peer average, which points to a valuation that already factors in a significant degree of optimism and leaves less room for disappointment if forecasts or sector conditions soften from current expectations.

Result: Price-to-earnings of 23.3x (OVERVALUED)

Still, the story can unravel if demand for high end EUV photoresists cools faster than expected, or if Tokyo Ohka Kogyo faces aggressive pricing from rival suppliers.
