An update from Mitsubishi Steel Mfg.Co., Ltd. ( (JP:5632) ) is now available.
Mitsubishi Steel Mfg. Co., Ltd. reported that blast furnace operations at Hokkai Iron & Coke Corp., its equity-method affiliate jointly operated with Nippon Steel, have resumed after a December 2025 fire damaged a hot-blast stove. The company is working toward stabilizing furnace operations and normalizing orders, which should restore a more reliable supply of hot metal to its key domestic production base, Mitsubishi Steel Muroran Inc., and strengthen the stability of special steel bar operations.
The blast furnace outage reduced production in the domestic steel bars business and cut operating profit for the year ended March 31, 2026 by about ¥3.5 billion due to lower sales volume, weaker productivity, and higher costs for temporary alternative sourcing. Although some negative impact is expected to linger into the first quarter of the fiscal year ending March 31, 2027, the company anticipates improved earnings from the second quarter onward, while also recognizing ¥0.9 billion in one-time restoration-related extraordinary losses linked to the accident.
