Over 400% Rally in Just One Year: Defence and Aerospace Multibagger Stock Hits Upper Circuit After Receiving Fresh Order from NATO Customer

Sigma Advanced Systems has been expanding from precision manufacturing into integrated Aerospace and Defence offerings, including advanced ammunition. The company has now secured a USD 102.23 million order, equivalent to about Rs 973 crore, to manufacture and supply Base Bleed Units for a North Atlantic Treaty Organization (NATO) customer.

The order is scheduled for execution over 12 months and adds a new ammunition component to Sigma’s existing capabilities in 155 mm artillery shells and fuzes. In scale terms, the contract is equivalent to roughly 12 per cent of the approximately Rs 8,000 crore Order Book that the company reported as of April 2026.

Base Bleed Units are installed in the rear portion of an artillery shell. They produce a controlled flow of gas during flight, reducing the aerodynamic drag created behind the projectile. This helps improve the shell’s range and operational effectiveness, making the technology relevant for modern long-range 155 mm artillery systems.

The contract supports Sigma’s stated plan to build a more integrated position in artillery ammunition manufacturing. The company said that combining shell, fuze and Base Bleed Unit capabilities could lower dependence on external suppliers, improve supply-chain control and allow it to offer a broader set of ammunition solutions to domestic and overseas customers.

Chief Executive Officer and Executive Director Sunil Kalidindi said repeat orders reflected customer confidence in the company’s execution and delivery capabilities. The opportunity, however, will depend on timely production ramp-up, quality compliance and supply-chain discipline. Defence manufacturing programmes often involve significant inventory, receivable and qualification requirements before contracts convert into cash-backed earnings.

Sigma Advanced Systems Share Price Hits Upper Circuit

As of 11:11 am on October 27, 2026, Sigma Advanced Systems shares were trading at Rs 862.20, up 5 per cent from the previous close of Rs 821.15. The stock has gained 435.47 per cent over one year, as a result it has delivered multibagger return.  At the prevailing price, it remained about 23 per cent below its 52-week high of Rs 1,119.40. The company’s market capitalisation stood at Rs 15,596 crore.

What This Means for Investors

The order strengthens Sigma’s effort to move beyond individual defence components and participate in a wider share of the 155 mm ammunition value chain. A Rs 973 crore programme to be executed within 12 months can improve near-term revenue visibility, subject to production schedules and customer acceptance. It also supports the company’s strategy of using integrated manufacturing to address international demand for advanced artillery ammunition.

The development is potentially supportive for the business case, but execution and cash conversion remain central. In FY2025-26, consolidated operating cash flow was negative at Rs 210.07 crore as receivables and inventory increased, while borrowings rose to Rs 300.39 crore as of March 31, 2026. The stock’s trailing price-to-earnings multiple of 94.46 times also indicates that investors are already assigning a high value to future order conversion. Delivery discipline, working-capital control and the quality of recurring earnings will therefore matter more than the headline contract value alone.
