Re: Cellcom Energy's Entry into an Agreement for the Purchase of Availability Certicates

The Company is pleased to announce that on December 31, 2025, Cellcom Energy¹ entered into an agreement to purchase availability certicates² from a third party not related to the Company, from an extra-high voltage power generation facility utilizing photovoltaic technology combined with storage (the Producer and the Production Facility, respectively), which is planned to operate according to the market regulation model instructions and is expected to connect to the grid during the second half of 2027 (the "Agreement").

Within the framework of the Agreement, Cellcom Energy committed to purchase availability certicates with a capacity of 50 megawatts for a period of 10 years from the start of the availability certicates supply to Cellcom Energy.

According to Cellcom Energy's estimates as of this date, the total cumulative payment for the purchase of the availability certicates for the entire duration of the Agreement is estimated at approximately NIS 350 million over the life of the Agreement.³
