This project report investigates the relationship between working capital management and profitability in ASX-listed construction companies in Australia. The study utilizes the cash conversion cycle (CCC) and its components (Average Collection Period, Average Payable Period, and Inventory Turnover) to measure working capital, with Return on Total Assets (ROTA) as the profitability measure. Secondary data from four ASX-listed construction firms were analyzed using Pearson’s Correlation and Linear Regression. The results reveal a negative relationship between working capital and profitability, although the statistical significance is not established. The research highlights a statistically significant negative correlation between the average collection period and profitability, suggesting that firms should focus on reducing this period to enhance profitability. The report includes an introduction, literature review, methodology, findings, discussion, and conclusion, along with limitations and suggestions for future research.
