Consolidation of power grid assetsThe information in this section is based on the results of the activities of JSC Rosseti Kuban for January — November 2025 and the Kubanenergo branch of PJSC Rosseti South for December 2025.

The consolidation of the grid assets is based on the consideration of proposals for the transfer of power grid facilities under the Company’s management and also on the identification of the power grid facilities that are potentially interesting for the consolidation, and subsequent collaboration with owners of such facilities for determining mutually beneficial conditions of the relevant transactions.

The activities of related territorial grid organisations (hereinafter referred to as TGOs) are monitored and analysed, and the structure of their ownership and key characteristics of the power grid assets owned by TGOs are reviewed. Tariff balance solutions for related TGOs are monitored to ensure compliance with regulatory requirements.

If violations are detected for third-party TGOs, the responsible officers of the Company send appropriate notifications to the regulatory and supervisory authorities.

The Company has compiled the list of projects for the consolidation of the Company’s power grid assets, which is updated quarterly and approved by the Company’s organisational and administrative document. The list of projects, in addition to those related to transactions for the consolidation of power grid assets that are currently under consideration and approval within the Company, includes all TGOs operating in the region. This list indicates actions to consolidate the assets of these TGOs, provided that there are appropriate agreements in place between the Company and each TGO.

To this date, the Company has signed the agreements on cooperation in the consolidation of the power grid complex with the executive authorities of the constituent entities of the Russian Federation in which the Company operates:

• 14.11.2011 – with the Government of the Astrakhan Region
• 28.09.2013 – with the Government of the Rostov Region
• 06.06.2019 – with the head of the Republic of Kalmykia

The Company constantly interacts with the titleholders or other owners of power grid facilities that are losing their TGO status in order to explore options for taking over the management of these facilities. The Company keeps track of the further ownership of power grid facilities operated by the organisations that have lost their TGO status.

In the reporting year, in connection with the assignment of the SGO status, the Company carries out as follows:

• Implementation of the provisions of Federal Law No. 35-FZ dated 26 March 2003 “On the Electric Power Industry” (as amended);
• Proper organisation of activities by branches of PJSC Rosseti South and their performance of SGO functions in the regions of presence, conclusion of agreements on transfer to gratuitous ownership and use, monitoring of previously concluded agreements.
