The rating scale and definitions stipulated in SEBI Master Circular for CRAs are being followed. # SEBI’s grievance redressal/dispute resolution and SEBI investor protection mechanisms such as SCORES and ODR shall not be available for activities and instruments, which fall under the regulatory purview of financial sector regulators other than SEBI. ICRA has undertaken a consolidated financial analysis of Roadstar Infra Investment Trust (RIIT/the Trust/ the InvIT) and its six underlying special purpose vehicles (SPVs). Of the six assets, four are under the National Highway Authority of India’s (NHAI) concession framework (three toll and one annuity), one toll asset under the Ministry of Road Transport and Highways (MORTH) and one annuity project from Kerala Road Fund Board (KRFB). The four toll road projects are Pune Sholapur Road Development Company Limited (PSRDCL), Moradabad Bareilly Expressway Limited (MBEL), Sikar Bikaner Highway Limited (SBHL) and Barwa Adda Expressway Limited (BAEL) and two annuity road projects are Hazaribagh Ranchi Expressway Limited (HREL) and Thiruvananthapuram Road Development Company Limited (TRDCL). RIIT holds 100% equity stake in MBEL, SBHL, BAEL and 90.01% in PSRDCL, 99.90% in HREL and 50% in TRDCL. Rationale ICRA has withdrawn the issuer rating assigned to Roadstar Infra Investment Trust (RIIT) at the company’s request in accordance with ICRA’s policy on withdrawal of credit rating. The rating reaffirmation factors in the long operational track record of the Trust’s SPVs (average toll collection record exceeding 10 years for the toll SPVs and more than 20 semi-annuities for the annuity SPVs). The toll portfolio reported a healthy performance, with toll collections registering a CAGR of 9.9% over FY2021-FY2026, supported by a traffic CAGR of around 7% during the same period. The asset portfolio is geographically spread across six states, namely Maharashtra, Rajasthan, Uttar Pradesh, West Bengal, Jharkhand and Kerala, with the top three states contributing around 86% of the consolidated revenues in FY2026. Following the prepayment of HREL’s senior debt in FY2026, the quantum of scheduled payments has reduced. The InvIT is in the process of refinancing the SPV-level debt at the InvIT level, which is expected to enable full cash-pooling benefits across all SP [Showing first 8,000 characters — download PDF for full document]
