L&T shares jump 4%, up nearly 10% in two days. What’s triggering this uptick?

Shares of construction major Larsen and Toubro (L&T) rose as much as 4% to hit an intraday high of Rs 3,646.50 on BSE on Wednesday, extending gains for a second straight session and rising 9% over the period.

The rally follows the company’s announcement that its water and effluent treatment (WET) business has secured a significant design-build-operate order from the Guwahati Metropolitan Drinking Water and Sewerage Board in Assam. As per L&T’s classification, a significant order falls in the range of Rs 1,000 crore to Rs 2,500 crore, though the exact value was not disclosed.

According to the company, the 24x7 water management project aims to provide a safe and continuous water supply to households in south-east Guwahati, while enhancing the reliability of the city’s water infrastructure. The scope of work includes the design, supply, installation, construction, testing, and commissioning of a barge-mounted intake system, raw water rising main, water treatment plant, reservoirs, booster pumping station, and a distribution network with household service connections.


The order further strengthens L&T’s presence in the northeast and reinforces the WET division’s focus on expanding its regional footprint and delivering sustainable, efficient water solutions across key geographies.

L&T shares have been under pressure since the onset of the US-Israel-Iran conflict in the Middle East, with the stock declining 15% over the past month. However, the company has indicated that it has not experienced any significant disruption from the ongoing conflict, with around 95% of its projects continuing as normal.

This is particularly noteworthy given L&T’s substantial exposure to the region. Deputy Managing Director and President Subramanian Sarma said the company operates more than 100 sites across major markets, including Saudi Arabia, the UAE, Qatar, Kuwait, and Oman. Its workforce in the region includes 8,000 employees, 2,000 family members, and about 20,000 contractual workers.

West Asia remains a key market for the company. As of December 2025, the region accounted for nearly 40% of L&T’s total order book and contributed around 75% to its international order book, according to Motilal Oswal Financial Services.
