Macro Bank (NYSE: BMA) director discloses multi-class holdings

Rhea-AI Filing Summary

Macro Bank Inc. director Brito Jorge Pablo filed an initial ownership report showing his existing stake in the company, rather than any new buy or sell transaction. He directly holds Class A ordinary shares, Class B ordinary shares, and American depositary shares of Banco Macro S.A.

He also reports additional Class A and Class B ordinary shares and American depositary shares held indirectly through Sanbay S.A., reflecting only his proportionate pecuniary interest in that entity’s holdings. Each American depositary share represents ten Class B ordinary shares, so these ADS positions correspond to a larger underlying equity interest.
