<![CDATA[General Background: Stock prices are important indicators in capital markets because they reflect market valuation of corporate ownership and are closely considered by investors. Specific Background: Infrastructure companies operate in capital-intensive and long-term projects, while the sector experienced a significant decline during 2022–2024. Interim financial reporting, firm size, and leverage therefore constitute relevant financial characteristics for examining stock prices. Knowledge Gap: Previous evidence presented in the study indicates inconsistent findings concerning the information content of interim financial reporting and the relationship between leverage and stock prices, creating a basis for examining these variables in contemporary infrastructure-sector conditions. Aims: This study examines interim financial reporting integrity, firm size, and leverage in relation to stock prices of infrastructure companies listed on the Indonesia Stock Exchange during 2022–2024. Results: Using purposive sampling, the study selected 30 companies from a population of 70, producing 270 observations. Multiple linear regression was conducted using SPSS. Interim financial reporting integrity and firm size showed positive and significant partial relationships with stock prices, with standardized coefficients of 0.634 and 1.045, respectively. Leverage showed a negative and significant relationship, with a standardized coefficient of −0.297 and p = 0.023. Novelty: The study examines the three financial characteristics simultaneously within infrastructure companies during the 2022–2024 period. Implications: The findings indicate that investors consider reporting integrity, corporate scale, and financial leverage when assessing infrastructure-sector stocks. Highlights: Conservatism accruals showed a positive standardized coefficient of 0.634. Corporate scale recorded a standardized coefficient of 1.045. Debt-to-equity ratio showed a negative coefficient of −0.297 with p = 0.023. Keywords: Degradation, Stock Price, Equity]]>
