CEO Message Commenting on the results for the quarter Mr. Martín Eurnekian , CEO of Corporación América Airports , noted : “ We delivered a solid operating performance in the second quarter , with total passenger traffic remaining largely stable at 20.6 million passengers , as broad- based growth across our portfolio helped mitigate the domestic decrease in Argentina . Revenue excluding Construction services continued to outpace traffic growth , rising 8 % year - over - year , supported by solid performance in both our aeronautical and commercial businesses . Revenue per passenger increased nearly 9 % , with every country in which we operate contributing to this improvement , including Argentina . Consolidated Adjusted EBITDA excluding IFRIC 12 reached $ 160 million , down 4.5 % year - over - year . Profitability was affected by headwinds in Argentina and , to a lesser extent , non - recurring costs and expenses in Uruguay . In Argentina , results were primarily impacted by the reduction in Flybondi's operating fleet , and a challenging comparison base for cargo revenues in 2Q25.By contrast , Italy , Brazil , Armenia and Ecuador each delivered double - digit year - on - year EBITDA growth , highlighting the strength of the diversification of our portfolio . Our financial position strengthened further , with cash and cash equivalents increasing to $ 692 million at quarter - end and net leverage at 0.5x . These metrics reflect continued cash generation , debt repayments and disciplined financial management , providing us with flexibility to execute our strategic priorities and pursue our acquisition strategy .
