Fujikura (TSE:5803) Lands Fusion Supply Deal As Valuation Questions Grow

Why Fujikura’s Fusion Tape Deal Matters For Investors

Fujikura (TSE:5803) just signed a landmark agreement with Commonwealth Fusion Systems to supply more than 10,000 km of high-temperature superconducting tape for ARC fusion power plants.

The commitment includes expanded manufacturing capacity at Fujikura to deliver this material at scale, positioning the business within the industrial supply chain that supports commercial fusion projects in the U.S. and Japan.

The Commonwealth Fusion Systems agreement lands on top of a powerful run in Fujikura’s stock, with a 1-month share price return of 13.07% and a year-to-date share price return of 82.10%, while total shareholder return over five years is extremely high. This suggests momentum that investors are now weighing against execution risks in fusion and broader valuation questions.

Preferred P/E of 44.9x for Fujikura: Is It Justified?

Fujikura now trades on a P/E of 44.9x, which is rich against many reference points. The question for you is whether the current earnings power and fusion story justify that kind of multiple.

The P/E ratio compares the ¥5,598 share price with the latest earnings per share and shows how many yen investors are willing to pay today for each yen of profit. For a manufacturer of telecoms, power systems, electronics and auto components with exposure to fusion infrastructure, a higher P/E can signal that the market is factoring in strong profitability and durable demand.

On the numbers provided, Fujikura is described as expensive on a 44.9x P/E compared with peer averages of 21.9x and the JP Electrical industry at 13.9x. Compared with an estimated fair P/E of 40x from the SWS fair ratio work, the current valuation also sits above the level that historical relationships suggest the market could move towards over time.
