About IRB Group: IRB Group is India’s leading and largest integrated infrastructure assets platform in the roads and highways sector, with a current portfolio of 27 revenue-generating highway assets aggregating to approx. ₹940 billion across 13 Indian states. With approximately 1.5 million vehicle crossings daily across its assets, the Group accounts for nearly one-tenth of India’s total toll revenue. Having successfully completed its asset creation phase, the Group has entered a cash-harvesting phase, supported by its InvIT monetization strategy and sponsor-led operating leverage. With a weighted average residual concession life of approximately 21 years, the portfolio provides strong visibility of long-term cashflows through predictable toll revenues, recurring O&M income and growing InvIT distributions. The Group has a clear roadmap to expand its asset base to approximately ₹1,400 billion by FY2029 with asset churn strategy and reinvesting proceeds into new opportunities to drive sustainable growth and long-term value creation.
