PRESS RELEASE Kyivstar Acquires Six Solar Power Plants, Further Diversifies Energy Sources Kyiv, New York, May 26, 2026 - Kyivstar Group Ltd. (Nasdaq: KYIV; KYIVW), the parent company of JSC Kyivstar (“Kyivstar”), Ukraine's leading digital operator and part of VEON Group (Nasdaq: VEON), today announced it is expanding its energy assets with the acquisition of six solar power plants in the Lviv region. The group of six acquired assets has a total installed capacity of 105 megawatts (MW). The total consideration paid is UAH 3.6 billion (USD 80.8 million). The solar assets being acquired generated approximately 113 GWh of electricity, while delivering approximately UAH 682 million of revenue and UAH 596 million of EBITDA in 20251. This acquisition marks another step forward in the development of Kyivstar’s energy generation portfolio. The company began expanding its energy asset base in December 2025 with the acquisition of Sunvin 11 (13 MW). Following the addition of the newly acquired assets, Kyivstar’s green energy generation has increased to 118 MW, enabling it to produce electricity equivalent to approximately 30% of its current annual consumption. Kyivstar will supply electricity produced by the newly acquired solar power plants to Ukraine’s unified energy system in accordance with current market and regulatory rules. This enhances the company’s ability to hedge electricity costs by supplying energy from these solar power plants to the national grid at market prices with green energy tariffs, supporting operational efficiency as connectivity demand continues to expand across Ukraine. “Renewable energy is a key focus area of Kyivstar’s investment portfolio, and this acquisition opens further opportunities for the use of green electricity to meet the company’s energy needs,” said Oleksandr Komarov, President of Kyivstar. “The development of our own energy generation is an important component of our long-term vision aimed at building safe, sustainable and efficient infrastructure. Together with VEON, we continue to increase investments in the Ukrainian economy because we believe in Ukraine and its successful future.” Investments in renewable energy enable Kyivstar to diversify its approach to meeting energy needs and build greater operational stability. With electricity demand growing alongside data traffic expansion, green energy projects support Kyivstar’s long-term energy strategy while strengthening Ukraine’s energy sector and advancing sustainable development goals. Kyivstar will continue to invest in initiatives that combine technological efficiency, alignment with ESG principles and support for the Ukrainian economy. 1 The revenue and EBITDA are based on unaudited management accounts.
