Report 13/2026 - Information on the Company's financial situation and assessment of the possibility of the Company and the Capital Group continuing operations

The Management Board of Mostostal Warszawa S.A. ("Company", "Issuer") announces that it has received information that based on preliminary financial data for the financial year ended December 31, 2025, the Company recorded significant losses, resulting in negative equity as of the balance sheet date and identified significant threat or doubts regarding the continuation of the Company's operations and its capital group.

In this context, the Management Board convened an Extraordinary General Meeting to adopt a resolution on the further existence of the Company, which was reported by the Company in current report No. 8/2026 dated March 30, 2026, fulfilling its obligation specified in Article 397 of the Commercial Companies Code.

Subsequently, after considering the majority shareholder's request, the Extraordinary General Meeting was canceled to allow shareholders to be acquainted with the Management Board's information estimating the Company's anticipated capital needs and regarding planned sources of financing these needs, and to enable shareholders to comprehensively analyze the materials and financial statements, which will be provided by the Company before such General Meeting, as reported by the Issuer in current report No. 12/2026 dated April 10, 2026.

Additionally, in the Management Board's assessment, the Company's liquidity projection indicates an increased need for funds to finance ongoing operations and meet liabilities as they become due. The assumption of the Company's and Group's continuation of operations is significantly dependent on the implementation of financing activities, particularly potential support from shareholders. Given the significant uncertainty regarding the possibility of the Company's continued operations, the Management Board is taking actions to ensure appropriate financing and improve the Company's liquidity situation.

These issues are also being analyzed as part of the ongoing audit of the Company's financial statement for the financial year ended December 31, 2025.

Further information, including the results of the auditor's work and the final assessment of the going concern assumption, will be disclosed in accordance with applicable regulations.
