India's state-owned National Aluminium Company (NALCO) reported a 16.6% fall ​in fourth-quarter profit on Thursday, as ‌higher costs and weaker alumina prices ​weighed on earnings.

* The ⁠company is India's largest producer of alumina, or aluminium oxide, used in the ‌production of aluminium and as a catalyst in petrochemical ‌refining.

* Net profit fell to ‌₹1,722 ⁠crores in the ⁠quarter ended March 31, from ₹2,067 crore a year earlier.

* Revenue from operations ​declined 5% ‌to ₹5,013 crore

* Expenses rose 10% to ₹2,898 crore, partly due to higher raw material ‌and operating costs.

* Analysts expected ​weaker alumina prices to limit margins at the company's ⁠alumina unit, despite support from firm aluminium prices, which rose on global ‌supply disruptions.

* Chinese domestic alumina prices fell about 5.5% quarter-on-quarter in the March quarter, as escalating U.S.-Israel tensions with Iran since late February weighed on demand from ‌China, the world's largest consumer, according ​to S&P Global.

* Revenue from the firm's second-biggest segment, chemicals, fell ⁠nearly 38%.

* Rival Vedanta reported a ⁠92.3% rise in profit on Wednesday, while Hindalco Industries is ‌yet to report.
