Genneia ^{Filed, US Offering, NYSE: GENN}

We are the leading renewable energy platform in Argentina, operating the country’s largest utility-scale wind and solar assets, complemented by strategically located thermal capacity. As of the date of this prospectus, we own and operate 2,128 MW of gross installed capacity, including 1,765 MW from renewables (wind and solar), and 363 MW from thermal generation. In May 2026, the San Rafael and Lincoln solar projects achieved full commercial operation, adding 180 MW and 20 MW of installed capacity, respectively. In June 2026, the San Juan Sur solar project achieved full COD for 129 MW of installed capacity. As of April 30, 2026, we operated approximately 23% of Argentina’s wind and solar installed capacity, according to CAMMESA. In May 2026, we were awarded a 13.2% indirect equity interest in Transener, Argentina’s principal high-voltage electricity transmission company, pursuant to a public tender process through which the Argentine government divested its equity interest in CITELEC, Transener’s controlling shareholder (the “Transener acquisition”). The acquisition was structured through Transmisión Eléctrica S.A., a special-purpose vehicle formed jointly with our consortium partner Edison Transmisión S.A. We believe this expected acquisition represents a strategically significant step that broadens our participation across the power value chain and reinforces our role in Argentina’s energy infrastructure.
