Frequently Asked Questions

What is the due diligence process for IPO?

The IPO due diligence process typically starts with readiness assessment, data room setup, and a review of financial statements, governance, litigation, tax matters, related-party transactions, contracts, and material risks. From there, advisors coordinate evidence-backed disclosures for the DRHP, align management narratives with supporting documents, and prepare responses for legal, auditor, exchange, and SEBI review. The goal is a complete, defensible filing record.
