Equity ownership and governance analyst

A large holder discloses a 21.09% beneficial stake in Auna S.A.

The filing states that the reporting group may be deemed to beneficially own 6,346,406 Class A ordinary shares of Auna S.A., which is about 21.09% of the outstanding Class A shares based on 30,095,388 shares outstanding as of June 30, 2025. This concentrated position is held through several Mexican entities (Grupo Angeles Servicios de Salud, Grupo Vazol, Corpvaza) and ultimately by Mr. Olegario Vazquez Aldir.

Control over the shares is described in terms of voting and dispositive power: the entities report shared voting and dispositive power, while Mr. Vazquez Aldir reports sole voting and dispositive power over the same 6,346,406 shares under beneficial ownership rules. This structure can matter for how this bloc participates in shareholder decisions such as director elections or other corporate actions.

The amendment references additional transactions listed in an attached schedule since the prior amendment, indicating ongoing activity in the position, though specific trade details are not included in the excerpt. Subsequent company and ownership disclosures will show how this stake evolves and how it is reflected in governance outcomes over future reporting periods.
