        <footnote id="F1">The price reported in Column 4 is the U.S. Dollar (USD) equivalent of Argentine Pesos (ARS) 2,400 per ordinary share. This equivalent is calculated based on an implied exchange rate of 1,567.3575 ARS per 1.00 USD, resulting in a reported price of USD 1.53 per ordinary share. This implied rate is derived from the closing price of the Issuer's American Depositary Shares (ADS) on the NYSE on June 30, 2026, relative to the closing price of the underlying ordinary shares on the Bolsas y Mercados Argentinos (BYMA), adjusting for the ratio of 10 ordinary shares per 1 ADS.</footnote>
