Analysts, however, stayed positive on the long-term outlook for the sector, as they believe the defence sector globally has entered a structurally elevated growth phase, driven by persistent geopolitical conflicts, rapid technological modernisation of weapons, and a multi-domain warfare.
"We believe that the expected sector growth trajectory offers a multi-year compounding story, combining sustained order inflows and efficient execution. We maintain a positive outlook on the sector and initiate coverage on eight companies. We prefer electronics value chain players and companies with proven technological capabilities to transition to a full solutions provider level from a subsystem manufacturer, said HDFC Institutional Equities.
The brokerage said rising capital expenditure by the Ministry of Defence (MoD), coupled with tighter import embargo are expected to serve as the structural growth drivers for the Indian defence industry.
Increased investments in indigenized R&D, technology modernisation, along with long term cross-border collaborations will be additional growth catalysts, it said.
"These strategic initiatives are expected to drive up sector evolution visibility, strengthen indigenization, and reinforce the long-term growth runway for Indian defence OEMs and subsystem suppliers," the brokearge added.
