This study examined the relationship between delivery risk management and logistics performance of e-commerce platforms in Abia State, Nigeria. Specifically, the study investigated how infrastructure risk management and security risk management influence delivery speed and order fulfilment accuracy. A cross-sectional survey research design was adopted, and data were collected from employees of registered courier service companies involved in e-commerce delivery operations in Abia State. A total of 250 questionnaires were administered, out of which 238 were validly returned, representing a response rate of 95.2%. The data collected were analyzed using descriptive statistics, reliability analysis, Pearson correlation, and multiple regression techniques. The findings revealed that infrastructure risk management and security risk management are widely implemented by courier companies and are positively associated with logistics performance outcomes. The regression results indicated that infrastructure risk management and security risk management significantly and positively influence delivery speed (R² = 0.49) and order fulfilment accuracy (R² = 0.46). The study further showed that both dimensions of delivery risk management jointly explain a substantial proportion of the variance in logistics performance. Consequently, all the formulated hypotheses were supported. The study concludes that effective delivery risk management plays a critical role in improving logistics performance within e-commerce operations. The study recommends that courier companies strengthen route planning, infrastructure adaptation strategies, and security mechanisms such as real-time parcel tracking and theft prevention measures to enhance delivery reliability and customer satisfaction.
