Shares of Adani Ports and Special Economic Zone rose around three point five per cent to an intraday high of Rs1,564.5 after its subsidiary signed a strategic memorandum of understanding with NMDC and Brazil's Vale on 21 February 2026. The stock was among the top gainers on the NSE Nifty50 and by 02:30 PM was trading two point two per cent higher at Rs1,544.9 compared with the previous session's close of Rs1,511.5. Market capitalisation stood at Rs3.55 trillion (tn) and the share price has recovered about 50 per cent from a 52-week low of Rs1,036.5 on 4 March 2025. Adani Gangavaram Port, a subsidiary of Adani Ports, executed the agreement at the India–Brazil Business Forum Summit in New Delhi during the official visit of the president of Brazil and the Indian commerce minister, according to an exchange filing. The memorandum established a framework for an iron ore blending facility and a dedicated special economic zone at Gangavaram and was said to strengthen the India–Brazil partnership. Under the pact the parties will jointly develop, operationalise and manage an integrated SEZ based ecosystem for blending, value addition and commercialisation of iron ore. The development is expected to increase capacity at Gangavaram Port to up to 75 million tonnes (mn t) and to position it as a hub for iron ore exports. Plans include fully mechanised berthing and cargo-handling to accommodate Valemax vessels with carrying capacity of up to 400,000 t, together with yard management and blending operations to improve supply chain efficiency. Separately, the company raised Rs10 billion (bn) through allotment of non-convertible debentures on a private placement basis. The filing showed that 100,000 rated, listed, secured and redeemable NCDs were allotted, each with a face value of Rs0.1 million (mn), aggregating to Rs10 billion (bn). Executives said the financing will support investments required to operationalise the planned infrastructure and to back the broader economic contribution from enhanced export capacities.
