Aegis Vopak Terminals, the largest third-party tank storage company in India, plans to raise Rs 3,500 crore through an initial public offering, having filed a draft red herring prospectus with SEBI. The IPO will consist entirely of a fresh issue, with no offer-for-sale component, ensuring all proceeds benefit the company. Additionally, the Mumbai-based firm may consider a pre-IPO placement of up to Rs 700 crore, which would be deducted from the fresh issue amount.
