Astra Microwave Products designs and manufactures RF and microwave systems, subsystems and components for defence, space, meteorology and hydrology, serving as a tier-1 supplier to DRDO, HAL, BEL and ISRO, and increasingly as an IP-led systems integrator. The business sits in a high-barrier niche: fewer than six Indian firms can mass-produce satellite payloads and advanced radar antenna arrays, and Astra holds a near-sole-provider position in several qualified programs. Its order book swelled to a record ₹4,300 crore after the July 2026 significant ₹2,205 crore order from HAL for Uttam radar critical subsystems, of which 66% is defence and 34% space and meteorology. Margin quality is evident in the 25% EBITDA margin for 9M FY26 and ~55% gross margin, which management considers near the top end, indicating pricing power and a mix shift toward complete systems.
The persistence of these economics rests on barriers that take decades to replicate. Astra spent 33 years to cross ₹1,000 crore revenue, a testament to the multi-year qualification cycles for defence products; its designation as development-cum-production partner for the Su-30 electronic warfare upgrade, along with exclusive in-house MMIC semiconductor capabilities, deepens the moat. The company owns full IP for several airborne and ground radars, and its long-standing relationships with DPSUs are built on reliability and cost competitiveness, with global feedback confirming 'nice' margins. These are not commodity electronics but mission-critical components where switching costs are prohibitive once designs are frozen.
The inflection is already occurring as development programs convert into production orders. Over the next 18-24 months, Astra will execute on the Uttam radar programme, with the first 112 units due by September 2027, and QRSAM missile subsystems with orders of ₹700-800 crore expected partly before FY27 year-end. The company guides to FY27 revenue of ₹1,350 crore (±25) and FY28 revenue of ₹1,600 crore (±50), implying a 15-20% growth trajectory. By the end of 2027, the space, meteorology and hydrology business will demerge into a separate listed entity, targeting ₹300+ crore revenue in its first year (FY28) at an 18-20% PBT margin, while the core defence business continues to scale with the Su-30 upgrade programs, new anti-drone systems, and the ARC joint venture targeting over ₹600 crore sales in FY27. The order pipeline of ₹8,000-9,000 crore over the next four years underpins a 'different trajectory' beyond FY28.
Management has walked the talk consistently. On the May 2025 call, they guided FY26 revenue of ~₹1,150 crore and order inflow of ₹1,300-1,400 crore; the actual FY26 result met both, with 9M EBITDA margin of 25% exceeding the implied 18-20% expectation. The FY27 revenue guidance of ₹1,350 crore was reiterated in August 2026, and Q1 FY27 orders of ₹185 crore (excluding the HAL order) track toward the ₹1,600 crore annual booking target. There has been no equity dilution, capex is guided at just ₹40-50 crore annually, and operating cash flow turned strongly positive at ₹370 crore in FY26 versus -₹99 crore the prior year. The demerger plan, new Astra-branded products expected before Diwali 2026, and the AMCA L1 status all point to execution beyond order book numbers.
The earnings path is quantified: FY27 EBITDA at a 25% margin on ₹1,350 crore revenue yields roughly ₹340 crore, and FY28 on ₹1,600 crore yields ₹400 crore, with further operating leverage from existing facilities. The main falsifier is execution slippage on the massive order book, particularly the Uttam delivery schedule of 112 units by September 2027, any delay in QRSAM finalisation, or customer approval bottlenecks that already impacted Q1 FY27 revenue. The single most important watchpoint is on-time delivery of Uttam units, as that validates the production ramp and triggers follow-on orders. If those milestones are met, the business will have entered a multi-year compounding phase where revenue growth accelerates toward the guided tripling by FY30-31, and the space demerger will unlock separate value without impeding the defence core.
