AMG is an independent asset management company based in Japan that manages equities, bonds, and other securities. This 19.56% shareholding represents approximately one-fifth of Muninova Holdings's issued shares, establishing AMG as a major shareholder in the company.

The report was filed on April 23, 2026, with an estimated acquisition amount of ¥42.82 billion.
