Kierke may be deemed, for U.S. federal securities law purposes, to be the beneficial owner of 59,939,770 Series B Shares consisting of:  (a) 3,698,977 ADSs representing 36,989,770 Series B Shares held by Operadora de Recursos Remer, S.A. de C.V., a subsidiary of Kierke and (b) 22,950,000 Series BB Shares held by ITA, which may be converted by ITA, with the unanimous approval of its shareholders, into Series B Shares at any time at the ratio of one Series BB Share for one Series B Share.

The beneficial ownership percentage is based on 277,050,000 Series B Shares of the Issuer outstanding, as reported by the Issuer on Form 20-F for the year ended December 31, 2025, filed on April 16, 2026, and takes into account the 22,950,000 Series B Shares issuable upon conversion of the 22,950,000 Series BB Shares held by ITA.
