 and himself. These instructions were ratified in 2004 by Mr. Roberto Garza Sada before a Notary Public.

Mr. Roberto Garza Sada passed away on 14 August 2010 and subsequently, in 2012, his daughters filed a complaint against Santander Mexico alleging it had been negligent in its trustee role. The lawsuit was dismissed at first instance in April 2017 and on appeal in 2018. In May 2018, the plaintiffs filed an appeal (recurso de amparo) before the First Collegiate Court of the Fourth Circuit based in Nuevo León, which ruled in favor of the plaintiffs on 7 May 2021, annulling the 2018 appeal judgment and condemning Santander Mexico to the petitions claimed, consisting of the recovery of the amount of 36,700,000 Alfa shares, together with dividends, interest and damages.

Santander Mexico has filed various constitutional reviews and appeals against the recurso de amparo referred to above, which have been dismissed by the Supreme Court of Justice of the Nation. As of this date, an amparo review filed by the Bank is pending to be resolved in the Collegiate Courts in the State of Nuevo León, thus the judgment is not final.

The Bank asked the Supreme Court of Justice of the Nation to take up the matter, what was accepted and consequently, the Supreme Court of Justice will resolve the matter. In addition, the Bank filed two recursos de reclamación against the non-admission of the recurso de revisión extraordinario issued by the then president of the Supreme Court of Justice of the Nation. On 25 June 2025, one of such recursos de reclamación was accepted and this decision was extended to the remaining one, both will now be resolved. In case that these recursos against the non-admission are resolved favourably, the Supreme Court of the Nation will then decide on the merits of the recurso de revisión extraordinario against the judgment which condemned the Bank.

At the current stage of the proceedings, the provisions recorded are considered to be sufficient to cover the risks deriving from
