Fujikura has reported a sharp rise in first-half profit, with earnings up 168.5% as demand for optical fibre products used in data centres lifted sales by more than half. The Japanese engineering group said profit attributable to owners of the parent reached ¥180.289 billion for the six months ended 30 September 2026, against ¥67.147 billion a year earlier.

Revenue rose 55.2% year on year to ¥867.433 billion, from ¥558.994 billion, while operating profit climbed 160.6% to ¥235.013 billion, from ¥90.171 billion. Morningstar described the result as a strong beat on higher optical sales and improved margins, and said it was raising its fair value estimate for the shares.

Optical demand drives the beat

Morningstar put the strength down to higher volumes and prices, faster delivery of optical components and a weak yen. Fujikura makes optical fibres, fibre cables and the fusion splicers used to join them, and demand from builders of AI data centres has become a central driver of its sales. The company has also announced plans to expand optical fibre production capacity, including a new factory at its Sakura plant in Chiba prefecture.

Mixed guidance for the full year

Management raised its full-year revenue forecast to ¥1.768 trillion, from ¥1.755 trillion, implying growth of 49.5% from the previous year. At the same time, it trimmed its operating-profit forecast to ¥429 billion, from ¥432 billion, and held its forecast for profit attributable to owners of the parent at ¥326 billion, which would be growth of 107.4%. Morningstar said the guidance cut was about 1% and reflected a stronger yen and lower tariff refunds.

The mixed outlook sets a clear test for the second half: sales momentum is strong, but converting extra revenue into profit will depend on margins, currency and the pace at which new capacity comes on stream. Fujikura shares traded at €18.07 on Lang & Schwarz at 15:24 CET on Wednesday 11 November 2026, according to AD HOC NEWS.
