Vedanta Q4 FY25 output: aluminium up, oil-gas down

What Vedanta reported for the March quarter

Vedanta said it posted higher output across several businesses in the fourth quarter of FY25, even as oil and gas production declined. In an update from New Delhi, the company flagged improved performance in aluminium, mined metal, iron ore, and saleable steel. The information was shared through a regulatory filing, which also described the March quarter and full-year trends.

The quarter matters because it closes the financial year and typically captures the impact of operational ramps, maintenance schedules, and logistics issues. Vedanta’s portfolio spans aluminium, zinc, oil and gas, steel, iron ore, and power. So production disclosures are closely tracked by investors as a proxy for volume-led earnings momentum.

Aluminium production in Q4 FY25: marginal rise

For Q4 FY25, Vedanta said aluminium production increased marginally by 1% to 6,03,000 tonnes compared with the same period in the previous fiscal year. The filing also said Vedanta reported record production figures across key business verticals for the quarter and the year ended March 31, 2025.

The company described this period as one in which it achieved “historic highs” in aluminium and zinc production. While it highlighted growth across iron ore, steel, oil and gas, and power sales, it also separately noted a decline in oil and gas production in Q4 FY25.

Full-year FY25: aluminium up 2% to 2,421 kt

On an annual basis, Vedanta said aluminium production rose 2% year-on-year to 2,421 kt for FY25. The filing also said fourth-quarter aluminium output was up 1%, consistent with the quarterly figure of 6,03,000 tonnes mentioned in the production update.

The company’s disclosure places focus on operational continuity and capacity utilisation. Annual volume growth, even in low single digits, is material in a commodity business where margins can fluctuate with input costs and price cycles.

Alumina output: annual rise, quarter affected by disruptions

Vedanta said alumina production increased 9% annually, supported by expansion projects. But it added that quarterly alumina output was impacted by temporary supply chain disruptions.

Alumina is a key input for aluminium smelting, and its availability affects cost and stability of operations. By attributing the quarterly impact to supply chain issues, Vedanta signalled that the constraint was not described as structural in the filing.

FY24 comparisons cited in the report: Q4 production details

The material also referenced FY24 disclosures, including PTI reports and an investor presentation. For Q4 FY24 (ended March 31, 2024), Vedanta reported total aluminium production of 5,98,000 tonnes, up 4% year-on-year from 5,74,000 tonnes in Q4 FY23.

On a quarter-on-quarter basis for FY24, the company disclosed that Q4 output was lower by 1,000 tonnes versus 5,99,000 tonnes, which it called the highest quarterly output ever. For FY24, total aluminium production was stated at 2.37 million tonnes, up 3% from 2.291 million tonnes.

Lanjigarh alumina and smelter split: what FY24 data showed

In the FY24 investor presentation data reproduced in the report, Vedanta disclosed alumina production at the Lanjigarh refinery at 484 kt in Q4, up 18% year-on-year and 3% quarter-on-quarter. The same dataset showed FY24 alumina production at Lanjigarh at 1,813 kt, up 1% year-on-year.

For aluminium, the investor presentation reported total aluminium production at 598 kt in Q4 FY24 (up 4% year-on-year) and 2,370 kt for FY24 (up 3% year-on-year). It also provided a plant-level split, with Jharsuguda at 452 kt in Q4 FY24 and BALCO at 146 kt.

Other operational metrics mentioned: zinc, power sales

The report cited Vedanta’s commentary that it achieved historic highs in aluminium and zinc production. In the FY24 section reproduced, Zinc India data included best-ever mined metal production of 1,079 kt in FY24, up 2% year-on-year, and silver volume of 746 tonnes, up 5% year-on-year.

The same reproduced bullets also stated that overall power sales were lower by 1% year-on-year and 2% quarter-on-quarter to 3,981 million units. These figures were presented as part of the FY24 operational snapshot contained in the investor materials.

Stock reaction captured in the report

The report also noted a market reaction linked to the Q4 FY24 aluminium production update. Vedanta advanced 2.26% to Rs 305.30 after informing that total aluminium production jumped 4% to 5,98,000 tonnes in Q4 FY24 compared with 5,74,000 tonnes in Q4 FY23.

While production numbers do not directly translate into earnings without price and cost context, such updates often influence near-term sentiment, especially in commodity-linked counters.

Key numbers at a glance

Why this update matters for investors

Vedanta’s Q4 FY25 update indicates a mixed quarter across its portfolio, with higher production in aluminium and other metals but a decline in oil and gas production. For diversified natural resource companies, volume trajectory is one of the cleanest indicators of operating execution, especially when commodity prices are volatile.

The alumina commentary is also relevant because it links quarterly output to “temporary supply chain disruptions” while emphasising expansion-led support for annual growth. Investors typically monitor alumina availability and integration levels because they can affect smelting costs.

Conclusion

Vedanta’s filings point to higher aluminium output in Q4 FY25 and a 2% rise in full-year FY25 aluminium production to 2,421 kt, alongside an annual 9% increase in alumina output despite quarterly disruptions. The company also indicated a decline in oil and gas production in Q4 FY25. Further operational and financial detail is likely to be tracked through subsequent regulatory disclosures and scheduled results communication for the year ended March 31, 2025.
