Insights

Institutional Ownership Analyst

Large passive stake disclosed: 1,140,197 shares (3.79%).

The filing indicates Bank of Nova Scotia holds 1,140,197 shares, equal to 3.79% of AUNA S.A.’s common stock, and reports sole voting and dispositive power over these shares. Because the stake is under 5%, the filer classifies this as non-control ownership and uses the Schedule 13G pathway rather than Schedule 13D.

Near term, market participants may view this as increased institutional ownership visibility; ownership changes above the 5% threshold would materially change disclosure obligations.

Compliance Officer

Amendment includes a foreign-regulation comparability certification.

The statement contains a certification that the foreign regulatory scheme applicable to the Bank is substantially comparable to U.S. institutions and offers to provide additional Schedule 13D-type information on request. The filing is signed by the bank's compliance lead on 10/08/2025.

This certification and the timely amended filing reduce procedural risk for the filer; any future reclassification or increased ownership would require updated filings and additional disclosures.
