Vedanta Group: Could Dependence on Bauxite Threaten the Group’s Earnings?

Synopsis: Aluminium remains Vedanta’s key revenue driver, contributing ~40 percent of Q2FY26 revenue of Rs. 39,218 cr. It is highly sensitive to raw material risks. Bauxite availability, regulatory approvals, and import cost volatility could materially impact margins and overall financial performance.

Aluminium has become a major earnings pillar for the Vedanta Group, but its performance is closely linked to the availability and cost of critical raw materials. Could disruptions or cost pressures in this segment have a meaningful impact on Vedanta’s overall revenue and profitability?

Vedanta Ltd, with a market capitalization of Rs. 2,66,316.98 crore, closed at Rs. 681.05 per equity share, up by 0.78 percent from its previous day’s close price of Rs. 675.75 per equity share.

Stock return

Vedanta Ltd has delivered returns across multiple timeframes, with a 1-month return of 18.16 percent, a 3-month return of 40.58 percent, and a 6-month return of 51.68 percent. The stock has delivered a 54.71 percent return in the past 1 year and in the longer frame of 5 years it has delivered a return of 289.27 percent.

Vedanta Limited is a diversified natural resources company with a global presence across metals, mining, oil and gas, and power. It operates in key segments including zinc, aluminium, copper, iron ore, oil and gas, and power, alongside manufacturing activities in steel products, glass substrates, ferro alloys, and cement, supported by large thermal and renewable power assets and port infrastructure in India.

Revenue Mix

As of Q2 FY26, Vedanta reported total segment revenue of Rs. 39,218 crore, after setting off inter segment revenue of Rs. 359 crore. Aluminium generated Rs. 15,677 crore, accounting for ~40.0 percent of total revenue, highlighting its central role in group earnings. Zinc, lead and silver (India) contributed Rs. 8,235 crore (21.0 percent), while copper added Rs. 6,604 crore (16.8 percent). 

Oil & gas revenue stood at Rs. 2,330 crore (5.9 percent), followed by power at Rs. 2,195 crore (5.6 percent). Iron ore contributed Rs. 1,449 crore (3.7 percent), zinc international Rs. 1,237 crore (3.2 percent), and other businesses Rs. 1,856 crore (4.7 percent). This concentration underscores why aluminium-related disruptions can have an outsized impact on Vedanta’s consolidated performance.

Key Challenges Facing Vedanta’s Aluminium Business

Bauxite Dependence

Aluminium production is highly raw-material intensive, with bauxite forming the foundation of the entire value chain, from alumina refining to smelting. Any interruption in bauxite supply immediately constrains refinery utilization, raises unit costs and disrupts downstream aluminium output. This structural dependence makes the aluminium business far more sensitive to input risks than Vedanta’s other segments.

Captive Mining Delays & Legal Risk

Vedanta’s long-term cost competitiveness depends on shifting to captive bauxite mining. While its Odisha-based mine has received initial forest clearance, multiple approvals remain pending, including environmental and final forest clearances. Continued delays due to regulatory processes and local opposition increase uncertainty around timelines, forcing the company to rely longer on external suppliers and imports at higher and more volatile prices.

The company’s bauxite sourcing from OMC is under legal dispute, creating a significant earnings overhang. An adverse verdict could result in retrospective payments for price differentials and compel Vedanta to procure future bauxite at substantially higher auction-linked prices. This would structurally raise input costs and reduce the margin cushion in the aluminium segment.

Imported Exposure

With overseas supply arrangements disrupted, Vedanta has become increasingly dependent on imported and spot-market bauxite. This exposes the aluminium business to global price fluctuations, freight cost volatility and foreign exchange risk. Such exposure reduces cost predictability and weakens Vedanta’s ability to plan long-term margins with certainty.

Capacity Expansion

Vedanta is expanding both alumina refining and aluminium smelting capacity. However, capacity additions without assured captive bauxite supply can backfire, as higher throughput amplifies raw material costs when sourcing remains external. This creates a risk where volume growth does not translate proportionately into earnings growth.

Execution Risk

Beyond regulatory and legal challenges, execution risks remain high. Any slippage in mine development timelines, community negotiations or regulatory compliance can further delay captive sourcing. This uncertainty keeps aluminium earnings vulnerable during a period when investors expect margin stability and cash flow support from the segment.

Financial Outlook

Revenue in Q2FY26 stood at Rs. 39,868 crore, increasing a 5.9 percent YoY growth over Rs. 37,634 crore in Q2FY25 and a 5.4 percent QoQ increase from Rs. 37,824 crore in Q1FY26, reflecting steady topline expansion. EBITDA rose to Rs. 11,396 crore, up 16.0 percent YoY from Rs. 9,828 crore and 14.9 percent QoQ from Rs. 9,918 crore, indicating strong operational performance and margin improvement during the quarter.

However, profit stood at Rs. 3,479 crore in Q2FY26, marking a sharp decline of 37.9 percent YoY compared to Rs. 5,603 crore in Q2FY25 and a 21.9 percent QoQ decline from Rs. 4,457 crore in Q1FY26.

Over the past five years, the company has demonstrated strong growth, achieving a revenue CAGR of 13 percent, a profit CAGR of 2 percent, and a price CAGR of 31 percent reflecting its operational performance and market confidence.

A return on equity (ROE) of about 38.5 percent and a return on capital employed (ROCE) of about 25.3 percent, and debt to equity ratio at 2.12 demonstrate the company’s financial position. The stock is currently trading at a P/E of 20.9x lower as compared to industry P/E of 47.8x.

Aluminium contributes the largest share of Vedanta’s revenue, nearly 40 percent in Q2 FY26. Even a small rise in bauxite costs can therefore hurt overall margins. This high dependence makes Vedanta more vulnerable to aluminium cost pressures than its peers, making stable and low cost bauxite supply crucial for keeping earnings steady.
