The Company had submitted the disclosure of the revision in credit ratings to the Stock Exchange on 30 July 2026. However, it is observed that the disclosure did not include the reasons for the downward revision as provided by CRISIL Ratings Limited, as required under the SEBI Master Circular dated 30 January 2026. The omission was inadvertent, and accordingly, the Company is submitting this revised disclosure incorporating the reasons for the downward revision. The revised credit ratings assigned by CRISIL Ratings Limited vide its letter dated 29 July 2026 are as follows: [Total Bank Loan Facilities Rated |Rs.642 Crore Long Term Rating Crisii BBB/Stable (Downgraded from ‘Crisi BBB+/Stable) Short Term Rating Crisil A3+ (Downgraded from ‘Crisil A2) Reason for the downward revision: Crisil Ratings has downgraded its ratings on the bank loan facilities of RPP Infra Projects Limited (RIPL) to ‘CrisilBBB/Stable/CriAs3i+l from ‘Crisil BBB+/Stable/Crisil A2".

EBITDA margin declined sharply to around 2.2% in fiscal 2026 from 7.5-8.5% in previous two fiscals. The decline is attributable to elevated establishment and mobilisation costs associated with new project execution, along with delays in the receipt of escalation claims. With lower operating profitability, interest coverage moderated to around 1.7 times from previous levels of 5.5-6.5 times. Operating performance over the medium term is dependent on project execution stabilization, escalation claims realisation, and cost pressures moderation, which will remain key monitorable. The ratings continue to reflect the extensive experience of RIPL’s promoters in the civil construction industry, the company’s above average financial risk profile and moderate working capital management. These strengths are partially offset by exposure to intense competition, susceptibility of operating margin to volatility in raw material prices, and risk related to the upcoming real estate project. This revised disclosure is being submitted pursuant to the observations received from BSE Limited. The Company regrets the inadvertent omission in the earlier disclosure and requests the Exchange to take this revised disclosure on record.

The downgrade reflects moderation in the company's credit profile resulting from weaker-than-anticipated operating performance. EBITDA margin declined sharply to around 2.2% in fiscal 2026 from 7.5-8.5% in previous two fiscals. The decline is attributable to elevated establishment and mobilisation costs associated with new project execution, along with delays in the receipt of escalation claims. With lower operating profitability, interest coverage moderated to around 1.7 times from previous levels of 5.5-6.5 times. Operating performance over the medium term is dependent on project execution stabilization, escalation claims realisation, and cost pressures moderation, which will remain key monitorable. The ratings continue to reflect the extensive experience of RIPL’s promoters in the civil construction industry, the company’s above average financial risk profile and moderate working capital management. These strengths are partially offset by exposure to intense competition, susceptibility of operating margin to volatility in raw material prices, and risk related to the upcoming real estate project. Analytical Approach Crisil Ratings has considered the standalone business and financial risk profiles of RIPL.

Nithya, Whole-time Director and CFO, also brings significant industry expertise. The experienced management team supports efficient project execution and order acquisition.

As on March 31, 2026, RIPL had an outstanding order book of over Rs 3,700 crore across 42 projects spread across 6 states, providing healthy revenue visibility over the next 24-36 months. The strong order backlog and established execution track record are expected to support steady revenue growth over the medium term. Above average financial risk profile: The networth was healthy at around Rs 526 crore, while gearing and total outside liabilities to adjusted networth (TOLANW) ratio are comfortable at 0.2 times and 1 time, respectively, as on March 31, 2026. Capital structure is expected to remain at comfortable levels over the medium term.
