Business model (BM) and strategy disclosures could provide investors with relevant information. This study offers a platform for future research on BM and strategy disclosure and is the first to analyse the change in BM and strategy disclosures after the introduction of an integrated reporting (IR) requirement, to propose a framework for disclosure quality analyses, and to analyse how companies disclose the relationship between their BM and strategy. The findings show that BMs and strategy were not disclosed before the requirement to publish an integrated report in South Africa, but were disclosed thereafter. By 2014, companies used diagrams, flow charts, and informative narratives of business plans and value chains. Companies now disclose their strategic goals more transparently, but still do not link these goals to BMs, key performance indicators, risks or opportunities. The findings provide insight into disclosures that improved since the IR requirement and matters that are still not fully disclosed, which would be of interest to regulators tasked with investor protection.
