Report 7/2026 - Estimated results for the year 2025

The Management Board of Mostostal Warszawa S.A. (the "Company") presents the estimated results for the year 2025:

Consolidated financial data (cumulatively for the year 2025):

- sales revenue: PLN 1,363 million,

- gross profit from sales: PLN 31 million,

- net loss: PLN 44 million (including net loss attributable to the shareholders of the Parent Company: PLN 45 million and net profit attributable to non-controlling shareholders: PLN 1 million).

Individual financial data (cumulatively for the year 2025):

- sales revenue: PLN 1,042 million,

- gross profit from sales: PLN 5 million,

- net loss: PLN 47 million.

The Company's Management Board informs that the individual statement of financial position (balance sheet) as of December 31, 2025, shows a loss exceeding the sum of the reserve and retained capital as well as 1/3 of the share capital. This is a result of creating provisions totaling PLN 49.4 million in the financial statement for 2025 for contractual penalties charged by the Ordering Party - PGE Energia Odnawialna S.A. in connection with the withdrawal from the Agreement dated July 22, 2022, concluded between the consortium of companies: GE Hydro France S.A.S. ("Leader" - consortium share 55.14%) and Mostostal Warszawa S.A. ("Partner" - consortium share 44.86%), with PGE Energia Odnawialna S.A., for the execution in the general contractor mode of the modernization of the technological part of ESP Porąbka-Żar, which the Company reported in Current Report No. 22/2025.

These provisions correspond to the amount of penalties according to the percentage shares in the consortium, and their creation does not limit the Company's right to claim these amounts from the Ordering Party or any other third parties involved in the Agreement, as the Management Board acknowledges that the Company is not responsible for their creation.

The creation of provisions resulted in a decrease in the Company's financial result for the year 2025 and consequently reduced the Company's equity below the sum of the reserve and retained capital as well as 1/3 of the share capital by the end of 2025.

At the same time, the Management Board indicates that the presented financial data in the financial statement for the year 2025, at the time of convening the Extraordinary General Meeting, is subject to review by an independent auditor, which may affect their final shape. This statement will then be subject to the opinion of the independent auditor and approval by the appropriate authorities of the Company.
