Purpose: This study reviews and integrates research on Initial Public Offerings (IPOs) in South Asia to consolidate dispersed evidence, trace intellectual developments, and identify future research directions.

Methodology: A dual approach is adopted, combining a bibliometric analysis of Scopus-indexed literature using Bibliometrix with a systematic review of 34 influential studies chosen for their citation relevance and regional representation. The synthesis is organized using the TCCM (Theory-Context-Characteristics-Methodology) framework.

Findings: The review indicates that IPO research in South Asia is heavily concentrated in India, with comparatively fewer studies from Pakistan, Bangladesh, and Sri Lanka. Existing scholarship primarily examines underpricing and short-run performance, while long-term outcomes, governance factors, and institutional influences remain insufficiently explored. The literature largely relies on signaling theory and information asymmetry, with limited incorporation of behavioral or institutional perspectives. Methodological approaches are dominated by event-study designs and regression models, whereas advanced econometric techniques and qualitative or mixed-method studies are uncommon.

Practical Implications: The study highlights research gaps, underscores the need for wider regional coverage, and encourages methodological and theoretical diversification to strengthen future IPO studies in the region.

Originality: This work represents the first comprehensive integration of South Asian IPO literature using both bibliometric mapping and a TCCM-based synthesis, offering a structured agenda for future research..
