Like any business enterprises, co-operatives cannot escape from the adverse impacts of the COVID-19 pandemic. Any disruptions brought about by the pandemic can negatively affect the business operations of co-operatives. This study reports the nature and extent of the effects of COVID-19 pandemic on 77 co-operatives in the Calabarzon region of the Philippines. The data were analysed using descriptive and inferential analyses. Chi-square test of independence was used to examine the association between co-operatives’ net surplus and two factors, the COVID-19 pandemic and whether or not co-operatives had a business continuity plan (BCP). The results revealed that most of the co-operatives had been severely affected by the pandemic. Among other things, co-operatives experienced several encumbrances, particularly affecting the supply chain, cash flow, and workforce. All the respondents felt that financial and technical assistance were needed to help co-operatives to weather the effects of the pandemic. The results further revealed that having a BCP was vital to help co-operatives build resilience amid the COVID-19 pandemic.
