Thank You Yours sincerely, For Larsen & Toubro Limited Subramanian Narayan Company Secretary & Compliance Officer (ACS 16354) Larsen & Toubro Secures Moody’s ‘Baa1’ Rating Two Notches Above India’s Sovereign Grade Mumbai, July 7, 2026: Larsen & Toubro Limited (L&T) has secured a ‘Baa1’ long term issuer rating with a ‘Stable’ outlook from Moody’s Ratings, reinforcing the Group’s robust credit profile and financial resilience. The ‘Baa1’ rating signifies a quality investment-grade credit profile, reflecting strong capacity to meet financial commitments and a low level of credit risk. It also underscores L&T’s prudent financial management and consistent operational performance. The 'Stable' outlook reflects expectations that L&T and its core international subsidiaries will maintain strict fiscal discipline, comfortable leverage levels and healthy operating margins as high-margin engineering services and large-scale EPC projects in West Asia continue to scale. Key Elements of Moody’s Rating Evaluation Moody’s comprehensive credit profile balances L&T’s structural operational strengths against inherent macro-level industry challenges: Core Credit Strengths: • Diversified conglomerate with deep track record. • Dominant market position & revenue visibility • Exemplary corporate governance • Favourable industry prospects in the domestic and international infrastructure landscape Notably, this premium rating stands two notches above India’s sovereign rating of ‘Baa3’, positioning L&T among an exclusive group of Indian multinational corporates evaluated stronger than the country’s sovereign rating. Moody’s, the global ratings major, has also assigned a matching ‘Baa1’ rating to L&T Hydrocarbon Saudi Company (a subsidiary of L&T), reflecting the business vertical’s tight operational integration with the parent Company and the strategic importance of Larsen & Toubro’s West Asia operations. Background: Larsen & Toubro is a USD 32 billion Indian multinational engaged in EPC Projects, Hi-Tech Manufacturing, Products and Services, operating across diverse domains and multiple geographies. With a strong impetus towards AI & technology, customer–focussed approach and the constant quest for top-class quality have enabled L&T to attain and sustain leadership in its major lines of business for eight decades.
