Facing 3D’s conglomerate-discount campaign against the president’s re-election (2025)

Ten trillion yen, measured by the quality of the explanation

The essence of this campaign can be read as concerning not the merits of the U.S. Steel acquisition itself but the standard of explanation required to justify an investment of that size. What 3D asked for repeatedly was a quantified account of returns above the cost of capital, and, for the listed subsidiaries, a test of whether Nippon Steel is their best owner. Winning 87% approval at the meeting and having discharged that duty of explanation are not necessarily the same thing. That among ten candidates the votes against concentrated on the president alone suggests a market taking the measure of whether the density of explanation matches the scale of the investment.

Correcting parent–subsidiary listings has become a shared issue in Japan’s capital markets since the Tokyo Stock Exchange’s reforms. That roughly 60% of minority shareholders at the NSSOL meeting backed 3D’s proposal shows that, even when a proposal is voted down, scrutiny of the conflict of interest between a parent and minority shareholders does not recede. As the cases of Sapporo and Seven & i show, it is not unusual for management later to carry out itself the substance of a proposal it defeated. How a company that has chosen an investment on the order of ten trillion yen will explain — and move — its remaining listed subsidiaries and cross-shareholdings, and whose hands will resolve the conglomerate discount, is a question carried over to the next annual meeting.
