The formation of an evidence bases regarding the losses incurred required proper documentation, systematisation and accounting recognition based on reliable and structured information on damaged or destroyed assets, incurred costs, and economic consequences. It was established that 60-70% of the significance in the process of verifying damages was ensured by documented accounting and registration data. The remainder was attributable to supporting analytical and expert materials that provided their interpretation and justification for further use in assessment and compensation procedures. It was substantiated that, as a result of simplified procurement procedures, the heterogeneity of procurement items within the Prozorro system, and the absence of a unified approach to the accounting recognition of costs, the risks of their misclassification as either current or capital expenditures increase. The structure of expenditures included costs for construction and engineering works, design and estimate documentation, technical and author supervision, engineering consultancy services, and the acquisition of materials and equipment. It also encompassed costs associated with ensuring physical protection, fortification, and restorative sheltering of critical infrastructure facilities, which collectively formed the overall cost of their restoration and the maintenance of uninterrupted operation. It has been demonstrated that the consequences of such uncertainty included the undercapitalisation of expenditures, distortion of accounting information, weakening of financial control, and a reduction in the evidential suitability of data for international compensation mechanisms. Based on an analysis of national and international regulatory documents, as well as procurement practices within the Prozorro system, it has been established that the key criterion for the proper classification of expenditures was their economic substance and the outcome of the transaction. The classification also considered its impact on the asset, rather than the formal designation of the transaction or the procurement item. The application of a criteria-based identification approach will contribute to improving the reliability of accounting information, strengthening financial control, reducing the risk of undercapitalisation, and forming an appropriate evidence base for subsequent compensation of losses.

The methodological basis of the study was economic and statistical analysis, comparative method, analysis of dynamic series, historical and logical method and the method of generalisation of thematic scientific research. It was established that the development of Poland's stock market was accompanied by a transition from institutional formation to functional maturity, which is manifested in a change in the sources of liquidity formation, investor structure and the nature of interaction with macroeconomic processes. At an early stage, market capitalisation increased from less than 1% of gross domestic product to about 20%, which reflected the creation of basic conditions for the market to function and its role in privatisation processes. After integration into the European Union, capitalisation more than doubled and exceeded PLN 600 billion, which was accompanied by an expansion of the investor base, an increase in trading volumes and increased liquidity. During the period of structural stabilisation, market capitalisation is set to increase to over PLN 1 trillion in 2021, and during the period of recovery growth - to PLN 2.3 trillion in 2026, reflecting a significant expansion of the market scale. Share trading volumes reached about PLN 470 billion per year, and the number of investment accounts exceeded 2.5 million, which indicates an increase in domestic demand. It was found that the market structure is determined by a high share of foreign investors, which exceeds 50% of trading volumes, as well as the concentration of liquidity within a limited group of the largest companies. It was proven that the dynamics of the stock market demonstrate high sensitivity to global financial impulses, which is manifested in synchronous fluctuations of indices and changes in trading activity. It is substantiated that the effectiveness of the stock exchange infrastructure as a mechanism for attracting investments is determined by a combination of the parameters of the primary market, the role of institutional investors, the level of liquidity and the degree of integration into the global financial environment. The practical significance of the study lies in the possibility of using the established dependencies and structural characteristics of the stock market to substantiate decisions on the development of the institutional environment, diversification of the investor base and increasing the market's resilience to external financial impulses.

The research was conducted as a theoretical and analytical study using methods of content analysis of academic sources, comparative analysis, secondary analysis of international analytical reports, systematisation, synthesis, generalisation and conceptual modelling. Examples of the Ukrainian enterprises Rozetka, Prom.ua and Nova Poshta were used to demonstrate that the renewal of sustainable business models is achieved through the platformisation of trade, the development of digital infrastructure for small and medium-sized enterprises, logistical optimisation, automated tracking and the expansion of channels for interaction with consumers. The study established that leadership shaped the strategic framework of a sustainable business model through defining the direction of development, coordinating resources, supporting change, managing knowledge, and developing the organisation's capacity for renewal. Creative management was identified as a mechanism for the practical renewal of the value proposition, business processes, partnerships, channels of interaction with consumers, and sources of value creation. The study determined that a sustainable business model is not formed as a static framework for a company's operations, but rather as a management system that combines leadership, innovation, knowledge, adaptability and competitiveness. The study noted that 86% of employers expect artificial intelligence and data processing to have a transformative impact on business, 39% of existing skills are changing or becoming obsolete, and 63% of employers identify the skills gap as the main barrier to transformation. It was also shown that 42% of executives consider the company's current model to be unsustainable in the long term without a change of course, confirming the need for managerial renewal of business models. The results can be used by business leaders, development managers, strategic management specialists and business owners to review business models, enhance managerial adaptability and improve the competitiveness of the enterprise.

The research methodology implied the use of methods of theoretical generalisation and systematisation, historical-logical, structural, systemic and comparative analysis, economic and statistical analysis, as well as case studies of Ukrainian and foreign enterprises. The main findings of the study showed that Ukrainian enterprises operate under conditions of macroeconomic and military challenges: in 2022, gross domestic product fell by approximately 29%, and a significant proportion of enterprises curtailed their activities, whilst in 2023 most enterprises resumed operations, albeit with reduced turnover and continuing resource constraints. Under these conditions, the feasibility of using maturity models as a tool for the systematic assessment and development of enterprise management systems is justified. It has been established that their application ensures the formalisation of business processes, improved manageability and the integration of digital tools into the management system. The theoretical and methodological foundations for the use of maturity models have been substantiated, which envisage their combination with business diagnostics, a focus on data-driven approaches and adaptation to the conditions of an unstable environment. Case analysis has shown that the implementation of maturity models at Ukrainian enterprises (the National Joint-Stock Company "Naftogaz of Ukraine", the Joint-Stock Company "Ukrnafta", the Ukrainian Gas Transmission System Operator) ensured the formalisation of processes and the standardisation of management, whilst at Blue People, project delay rates fell from 80% to 1%, costs from 55% to 12%, and revenue increased by 440%. The approaches to adapting maturity models involved their phased implementation, integration with digital management tools, simplification of assessment procedures, and combining process standardisation with the flexibility of management systems. The practical significance of the study lies in the possibility of using appropriate approaches to assess the level of development of management systems and improve business processes in enterprises.
