The specific objectives of the study are to identify the various components of working capital in manufacturing companies in the South East State of Nigeria; evaluate the impact of working capital management on the productivity of manufacturing companies in the South East State of Nigeria. A panel data methodology was used with different regression estimators to analyze this relationship based on a balanced panel of 10 listed firms during the period 2008-2017. It was discovered that cash collection period and cash payment period exerted a negative impact on return on assets, though the impact was only significant for cash payment period on the ground of ?0.064 (p = 0.000 < 0.05), as against the estimate for cash collection period that stood at ?0.032 (p = 0.077 > 0.05). Also discovered was that both the current ratio and inventory period exerted a positive impact on return on assets, though the impact was only significant for current ratio on the ground of 8.172 (p = 0.000 < 0.05), as against the estimate for inventory period that stood at 0.045 (p = 0.438 > 0.05). The study concluded that working capital management affected firms' profitability in Nigeria. Therefore, it was recommended that while the shorter collection was maintained, payment to creditors should not be elongated so as to enjoy cash discount (if any) and that firms should be proactive in the management of raw materials in order to avoid idle resources that might negatively impact their financial performance.
