Ratings also take cognisance of healthy growth in RRWL’s scale of operations in FY26 (FY refers to April 1 to March 31) and Q1FY27 aided by successful completion of its large-sized copper tubes manufacturing capacity and its adequate liquidity. However, rating strengths are partially offset by RRWL’s thin profitability, due to limited value addition, leveraged capital structure, and moderate debt coverage indicators on the back of recently completed debt-funded capex and high reliance on debt for working capital requirement, susceptibility to copper price volatility, and prevalent competition in the copper winding wire industry from the unorganised segment. Rating sensitivities: Factors likely to lead to rating actions Positive factors • Optimal utilisation of expanded capacity, resulting in substantial growth in scale of operations to more than ₹7500 crore on a sustained basis, while maintaining its profit before interest, lease rentals, depreciation, and taxation (PBILDT) margin over • Improvement in debt coverage indicators marked by PBILDT interest coverage above 4x and total debt to PBILDT (TD/PBILDT) below 2.50x on a sustained basis. Negative factors: • Large-sized debt-funded capital expenditure or higher-than-envisaged increase in working capital intensity, leading to deterioration in overall gearing above 2x on a sustained basis. • Deterioration in scale of operations or profitability margin compared to that envisaged leading to moderation in PBILDT interest coverage below 2.50x on a sustained basis. Analytical approach: Consolidated CARE Ratings Limited (CareEdge Ratings) has taken a consolidated view of RRWL and its subsidiary, Tefabo Products Private Limited (TPPL; 64% stake) and joint ventures (JVs) - EPAVO Electricals Private Limited (EEPL; 50% stake), and RR-Imperial Electricals (10% stake), considering managerial and operational linkages. Details of the entities consolidated are shown in Annexure-5. Outlook: Positive Outlook on long-term rating of RRWL has been changed to 'Positive' on CareEdge Ratings’ expectation of sustained healthy growth in its scale of operations, driven by the recent operationalisation of its large-sized copper tube manufacturing capacity, which is expected to result in improvement in RRWL’s overall financial risk profile. Outlook may be revised to ‘Stable’ in case the company is unable to achieve envisaged scale of operations resulting in lower-than-expected debt coverage metrics. 1SEBI: Securities and Exchange Board of India; RBI: Reserve Bank of India; MCA: Ministry of Corporate Affairs; IRDAI: Insurance Regulatory and Development Authority of India; PFRDA: Pension Fund Regulatory and Development Authority. 2Complete definitions of ratings assigned are available at www.careratings.com and in other CARE Ratings Limited’s publications. 1 CARE Ratings Ltd.

In addition to its core winding wire business, the company has diversified into manufacturing copper tubes, strengthening its product portfolio, and enhancing its presence in the copper value chain.

Revenue growth was supported by 9% y-o-y volume expansion in the copper winding wire segment and a robust 113% y-o-y increase in the copper tube segment, aided by the ramp-up of recently commissioned large-scale capacity. The company’s installed capacity for the copper winding wire segment has consistently increased by ~1.5x in last five years ended in FY26. Despite the significant capacity expansion, utilisation levels remained at ~73% in FY26 (for copper wires segment). CareEdge Ratings expects sustained healthy growth in RRWL’s scale of operations supported by healthy demand for copper wires and ramp up of commercial production in its copper tubes division.
