What stands out

  • A specialist power plant engineering firm whose main business is decommissioning work at the Fukushima Daiichi nuclear plant
  • Revenue and profit both forecast to rise for the year to July 2026: about 9.8 billion yen in sales, with operating profit up roughly 69%
  • Plans a dividend of 20 yen per share from listing, and needs only about 70,000 yen to apply

What could go wrong

  • About 54% of revenue comes from Tokyo Electric Power Holdings, so it depends heavily on one customer
  • Changes to the decommissioning schedule or to national nuclear policy could shift when orders arrive and how the business performs
  • The offering ratio is 37%, on the high side, so supply is likely to weigh on the shares immediately after listing

About the company

A power plant engineering firm whose main business is decommissioning work at the Fukushima Daiichi nuclear plant, alongside nuclear plant maintenance and renewable energy.

How it makes money

Its core business is nuclear plant engineering: decommissioning work at the Fukushima Daiichi plant, maintenance and component replacement, and preparation work for restarting reactors. In the year to July 2025 this engineering business accounted for about 87% of revenue. It also runs a renewable energy business operating and maintaining solar and biomass generating facilities. Around 54% of revenue comes from Tokyo Electric Power Holdings.

Where growth is meant to come from

Decommissioning Fukushima Daiichi is expected to require spending of 260 to 300 billion yen a year through fiscal 2028, so engineering demand looks secure for some time. Over the longer term the company is aiming at decommissioning elsewhere, maintenance tied to reactor restarts, and expansion of its renewable energy business. For the year to July 2026 it forecasts revenue of about 9.8 billion yen and operating profit up roughly 69%.
