MBS to buy back shares, partner with Doughnut Robotics on AI construction

MBS announced on October 16, 2025, a resolution to acquire up to 100,000 of its own common shares, representing 1.42% of its outstanding stock. The total acquisition value is capped at JPY 150,000,000, with purchases to occur on the Tokyo Stock Exchange between October 17 and November 20, 2025. This move aims to enhance capital efficiency. MBS currently holds 700,049 treasury shares, with 7,031,951 shares outstanding.

Concurrently, MBS is forming a capital and business alliance with Doughnut Robotics Co., Ltd. through a third-party allocation. MBS will acquire 45,024 common shares of Doughnut Robotics for an estimated JPY 99,998 thousand, with the acquisition expected on October 31, 2025. This partnership aims to address labor shortages and improve efficiency in the construction and civil engineering industries by integrating MBS's construction expertise with Doughnut Robotics' humanoid AI robots.

The business collaboration encompasses providing construction technology know-how, offering test sites for robots, evaluating safety, and granting exclusive sales agency rights for humanoid robots in the construction sector. Both companies will jointly develop technology to enable humanoids to perform tasks such as scaffolding, painting, security, and material handling, with the goal of transforming construction sites. The impact of this alliance on MBS's financial performance for the fiscal year ending May 2026 is currently considered minor.
