Hitachi Construction Machinery (6305) Approves Share Buyback of Up to ¥34.0 billion | TDnet Disclosure

Hitachi Construction Machinery (6305) disclosed on 2026-08-19 through TDnet that its board had approved a share buyback of up to ¥34 billion, or 6,420,000 shares. The company builds construction and mining equipment and also runs a components business covering engines and hydraulic equipment.

Purchases will be made in the open market through a discretionary trading arrangement with a broker, running from August 19 to November 30, 2026. Unlike a ToSTNeT-3 block that settles in one session, this format accumulates shares gradually across the period as prices allow.

The ¥34 billion cap divided by the 6.42 million share cap implies ¥5,296 per share, about 98% of the ¥5,420 close on the day of disclosure. In other words, the frame is sized for purchases at close to the current market price. The filing does not give a percentage of shares outstanding, so the supply effect has to be judged by setting the 6.42 million share cap against the float. Spread evenly across the window, that works out to roughly 90,000 shares a session. Buyback caps are authorisations rather than promises, and the amount actually spent can be lower. Nothing in the disclosure addresses cancelling the repurchased shares.

*Speculation: An implied price so close to the market price suggests the company intends to work through the frame steadily rather than wait for a particular level, leaving a source of buying in the market until the end of November.
