Ravi Singh, Chief Research Officer at Master Capital Services, said the key factors to track will be whether the company can sustain revenue growth, improve profitability and execute its growth plans while maintaining healthy working capital and operating cash flows.

“Long-term investors may continue to monitor the company’s defence electronics and imaging technology business, supported by demand for advanced surveillance, thermal imaging and defence modernisation solutions,” Singh said. Rather than focusing solely on its listing-day performance, investors may track quarterly revenue growth, order execution, EBITDA margins, order book development and operating cash flows to assess the company’s long-term growth prospects.
