On April 13, 2023, Enviro Infra Engineers' shares surged nearly 15% in intraday trading on the Bombay Stock Exchange (BSE), reaching an intraday high of ₹199.15. This rise occurred despite a broader market decline, with the equity benchmark Sensex falling over 2%. The stock's increase was driven by the company's announcement of receiving a letter of empanelment for two sewage treatment projects in Maharashtra, valued at ₹587.208 crore. The projects, located in Pune and Nashik, will be executed under the Swachh Bharat Mission (Urban) 2.0 on an engineering, procurement, and construction (EPC) basis, with a completion timeline of 24 months. Over the past month, Enviro Infra shares have risen 31%, while the Sensex has only increased by 3%. However, the stock is down 2% year-to-date, contrasting with the Sensex's 10% decline during the same period.
