Geographical indications (GIs), protected by the European Union with the collective marks of PDO (protected designation of origin), PGI (protected geographical indication), and TSG (traditional specialty guaranteed), play an important role in the social and economic system. They not only guarantee food needs, but promote correct consumer information, protect local food, and play a role in the environmental and social sustainability of rural areas. In Italy, Parmigiano Reggiano (PR-RE) PDO cheese is ranked second in foods with the GI protection mark by turnover. This research aims to assess the financial sustainability of the firms registered in the PR-RE PDO consortium using financial statement (FINSTAT) analysis. Financial ratios (FR) and the EM-Score were applied to assess firms’ performance, financial risk, and credit score. The analysis distinguished firms by legal form, cooperative and non-cooperative, and altitude range—plain hill and mountain. The main findings of the research were as follows: (1) a better performance of lowland non-cooperative firms and lower financial risk, (2) a longer duration of the inventory cycle of cooperative firms, and (3) a greater financial risk in mountain cooperatives. The results provide indications for improving firms’ performance and for designing financial instruments for the sector. To our knowledge, this is the first research to carry out an analysis of all the available FINSTATs of firms in the PR-RE PDO sector.

Under Article 2135 of the Italian Civil Code, agricultural biogas firms represent a strategic expansion of traditional farming boundaries. By driving corporate diversification, environmental sustainability, and circular economy objectives, these firms are attracting substantial investment within the European Union and particularly in Italy. However, the bioenergy sector is structurally characterized by high capital intensity and low asset turnover efficiency, necessitating extensive external financing. Despite these unique dynamics, empirical evidence regarding their capital structure remains scarce. To address this literature gap, this study analyzes a 10-year balanced panel dataset comprising 350 firm-year observations, representing the most extensive research conducted to date on specialized Italian agricultural biogas firms. To answer the research questions (RQs), financial ratios (FRs) were calculated from financial statement (FINSTAT) data by applying the DuPont decomposition framework. The main findings are that (1) firms exhibit high profitability, but with some cases of loss and equity erosion; (2) firms exhibit low capital turnover and some cases of short-term financial unsustainability; (3) capital structure is often characterized by excessive debt. Our findings reveal a capital-intensive sector that, while profitable, remains vulnerable to financial instability. We provide actionable insights for practitioners and policymakers to foster a culture of financial sustainability. Our findings help mitigate information asymmetries, fostering more transparent market operations and ensuring that public subsidies are channeled into resilient capital structures.
