Consolidated EBITDA for the second quarter stood at ₹13,757 crore, registering a growth of 42% year-on-year. Quarterly Net Profit was ₹7,533 crore compared to ₹4,741 crore in the same quarter last year. This record performance was underpinned by the strength of Hindalco’s integrated business model led by a solid primary upstream business complemented by strong contributions from its downstream business. The Copper business reported its highest-ever quarterly EBITDA, while Novelis sustained improved performance building on Oswego’s normalisation. Together, the non-LME-linked businesses contributed almost 50% to the company’s earnings reflecting sustainable growth despite LME volatility and global macroeconomic headwinds. *comprising Novelis, Copper, Aluminium Downstream Commenting on the results, Mr. Satish Pai, Managing Director, Hindalco Industries, said, “Hindalco delivered its strongest-ever quarterly performance, with Revenue and PAT surpassing their previous highs. Our long-term strategy of building an integrated business model across upstream metals and downstream value-added products is translating into a stronger and more resilient earnings profile. While the Aluminium Upstream business registered an EBITDA growth of 55%, our non-LME- linked businesses also recorded EBITDA growth of nearly 50%, supported by stable operations at Novelis and a record quarter in the Copper Downstream, and Aluminium Downstream businesses. Looking ahead, the commissioning and ramp up of Bay Minette, copper recycling, aluminium battery foil, Aditya FRP and Inner Grooved Tubes will further accelerate the share of our non- LME-linked businesses. On the upstream front, our aluminium refinery and smelters, copper smelters and coal mine projects remain on track. Together, these investments reinforce Hindalco’s position as an integrated global metals company, combining upstream strength with downstream growth to deliver sustainable, long-term value in all market cycles.” Summary of Consolidated Financial Highlights for the Quarter ended September 30, 2026 (₹ Crore) Particulars Q2 FY26 Q2 FY27 Growth % Revenue from Operations 66,058 91,708 39% EBITDA 9,684 13,757 42% PBDT 8,881 12,824 44% Exceptional Income/ (Expenses) (Net) (182) 284 - Profit Before Tax (After Exceptional Item) 6,540 10,594 62% Profit/ (Loss) After Tax 4,741 7,533 59% EPS (₹/Share) - Basic 21.35 33.93 59% Advancing Sustainably • Operationalised a 65 MW round-the-clock (RTC) renewable energy project at Aditya Aluminium, making Hindalco the only company in India with an operational captive RTC renewable energy plant. • Commissioned an additional 173 MW of renewable energy capacity in Q2, taking Hindalco’s total installed renewable energy capacity to 643 MW. • Achieved 110% copper slag utilisation in Q2, including the utilisation of accumulated stock, supported by continued demand from the abrasives and ready-mix concrete industries. • Strengthened water stewardship, with year-on-year improvements in water recycling rates to 33% in the Aluminium business and 24% in the Copper business.
