Bunka Shutter Co., Ltd. ( (JP:5930) ) has provided an update.
Bunka Shutter will ask shareholders at its June 17, 2026 ordinary general meeting to approve potential countermeasures against a possible large-scale share purchase by investor group Dalton Parties. The board, including eight independent outside directors, unanimously agreed to seek advance shareholder approval for implementing these defenses if Dalton initiates a large-scale purchase without following established procedures under the company’s existing response policies.
The company deems the situation an emergency, citing a concrete risk that Dalton could bypass the policy framework, potential harm to Bunka Shutter’s medium- to long-term corporate value, and a recent Dalton-backed proposal to install its affiliates as directors that may push the firm toward an MBO geared to short-term gains. Institutional investors have expressed concerns about conflicts of interest between Dalton and general shareholders, and the planned vote is positioned as a move to protect shareholder interests and reinforce governance around unsolicited control attempts.
