Apollo Micro Systems ends FY26 with record growth and a bigger defence footprint

Apollo Micro Systems closed Q4 FY26 and the full year ended 31 March 2026 with its strongest reported operating and profit performance so far. Consolidated revenue from operations rose to INR 2,932.6 million in Q4 FY26, up 81.3 percent year on year. Full year consolidated revenue reached INR 9,043.2 million, up 60.9 percent. Operating leverage was visible in profits. Consolidated EBITDA excluding other income grew 88.0 percent year on year in Q4 FY26 to INR 676.4 million, while full year EBITDA grew 68.8 percent to INR 2,181.6 million. Profit after tax more than doubled in Q4 FY26 to INR 367.9 million, and rose 90.5 percent for the year to INR 1,073.8 million.

The quarterly outcome matters because it came alongside a strategic transition in the business model. Apollo is positioning itself as a fully integrated defence company spanning explosives, subsystems, systems, platforms, weapons, and weapons integration. The FY26 print shows the financial weight of this ambition. Growth is no longer only a function of being a niche electronics partner. It is now tied to a broader product slate that includes underwater mines, rockets, aerial bombs, fuzes, warheads, homing systems, navigation systems, and new technology areas such as directed energy weapon subsystems.

Operationally, the company also points investors to a key nuance. Quarterly comparisons can be noisy in defence manufacturing because deliveries depend on program schedules and product mix. Management argues that the annual view is the better yardstick. Still, Q4 FY26 delivered the highest ever quarterly revenue, EBITDA, and PAT, which suggests not just cyclicality, but improved execution and scale.

A performance year anchored in scale and margins

On the consolidated numbers, FY26 EBITDA margin excluding other income improved to 24.1 percent from 23.0 percent in FY25. PAT margin improved to 11.9 percent from 10.0 percent. This gradual margin expansion is one of the most important signals in the presentation. Apollo is operating in categories where qualification cycles are long, customer switching costs are high, and design ownership is defensible. When volume rises on already-qualified systems, margins tend to expand because fixed costs are absorbed more efficiently.

Standalone performance provides an additional lens into the core defence electronics business. Standalone revenue from operations was INR 7,648.5 million in FY26, up 36 percent year on year. Standalone EBITDA rose 66 percent to INR 2,138.8 million, with EBITDA margin expanding to 28.0 percent from 23.0 percent. Standalone PAT increased 111 percent to INR 1,205.8 million, with PAT margin rising to 15.8 percent from 10.2 percent. The standalone margin profile is materially higher than consolidated, which likely reflects consolidation of the acquired explosives business and the costs of building capacity for the next growth phase.

Apollo also highlights improvements in efficiency metrics over time. ROCE increased to 18.23 percent in FY26 from 10 percent in FY21. Debt to equity reduced from 0.54 in FY25 to 0.4 in FY26. Working capital cycle days reduced from 626 days in FY21 to 359 days in FY26. These are not cosmetic changes. Defence manufacturing often requires high inventory and milestone-based collections. A reduction in working capital days suggests tighter program management and a better conversion of production into cash, although FY26 consolidated operating cash flow remained negative at INR -1,297.6 million, and investing cash flow was INR -3,569.0 million.

From electronics partner to integrated weapons company

The strategic story in this presentation is broader than revenue growth. Apollo positions itself as a fully integrated defence company that spans explosives and high-energy materials, electronics and ruggedized subsystems, complete systems, and weapon platforms. The portfolio described is wide. It includes missiles, drones, rockets, underwater weapons, vehicle-mounted counter-drone systems, aerial bombs, explosives, directed energy weapons, and ammunition.

A key capability is Apollo’s work in underwater mine families. The company states it is the approved production agency for the Multi-Influence Ground Mine under DcPP by DRDO. It also highlights first indigenized limpet mines and moored mines. The narrative connects this to modern naval deterrence, where mines act as area denial systems that can shape adversary movement. It reinforces the positioning: Apollo is not only supplying components, it is delivering complete weapon offerings in categories where India historically had limited private sector depth.

Another differentiator is the Universal Homing System for heavy weight torpedoes, developed in collaboration with DRDO. Apollo states it is the only qualified vendor for homing systems of heavy weight torpedoes and that it has invested six years in developing this technology. It also claims readiness for large-scale production through its Unit III facility. If execution matches this claim, the financial impact can be meaningful because torpedo and naval programs typically require long-term support, upgrades, and multi-year production runs.

The company’s technology roadmap expands into navigation and seekers. It holds a license to manufacture inertial navigation systems and is developing MEMS-based INS, fiber optic gyro-based systems, and ring laser gyro-based systems. It also states RF seeker development has been initiated. These are foundational technologies that can be reused across multiple missile types and platforms, which is why they matter beyond the immediate program.

Directed energy weapon subsystems are also emerging as a growth vector. Apollo cites transfer of technology for a multi-channel 10 kW laser directed energy weapon system from DRDO-CHESS, subject to licensed agreement and regulatory requirements, and transfer of technology for an EO tracking system with EO sensors for DEW from DRDO-IRDE. This part of the story is about optionality. DEW adoption in defence takes time, but subsystem capability can place the company early in the value chain.

The explosives acquisition changes the economic model

A major event shaping FY26 is the acquisition of IDL Explosives Ltd through Apollo Defence Industries Pvt Ltd. The presentation states that Apollo Defence Industries acquired 100 percent equity stake in IDL Explosives for INR 107 crore in an all-cash transaction. The acquired company manufactures packaged and bulk explosives for mining and infrastructure, and has a land bank with only around 40 percent utilized, creating a brownfield expansion option.

Apollo’s strategic logic is vertical integration and market expansion. Defence weapons and munitions require high-energy materials and propellants. By owning explosives capability, Apollo seeks to reduce reliance on external suppliers, improve control over costs, and expand addressable markets, including exports. Management also frames the acquisition as turning near-term challenges into opportunities. It references volatility in gross margins, a temporary ban by a large customer, and underutilized capacity. The company states the Coal India ban was removed, and that IDL secured a running contract for supply of bulk explosives amounting to INR 4,193.96 million and an export order value of INR 15 million, with cumulative orders of INR 4,208.96 million.

This matters for investors because it suggests two parallel engines. The legacy defence electronics and systems business benefits from increasing indigenous defence procurement. The explosives subsidiary provides annuity-style mining and infrastructure demand while also building a base for defence explosive manufacturing. The presentation states that under the IDR Act, 1951, a license authorizes manufacture of HMX and TNT, with stated capacities of 50 MTPA for HMX and 500 MTPA for TNT, and a license validity up to 15 years.

At the same time, the cash flow profile should be read carefully. Consolidated operating cash flow was negative in FY26 and investing cash flow was significantly negative, while financing cash flow was positive. This aligns with a company investing in capacity, integration, and potentially inventory to support production ramps. Management also addresses working capital directly. It argues high working capital days are structural due to the need to maintain defence-critical inventory and the longer holding periods during development and production phases.

Capacity expansion, R&D intensity, and a long-cycle order book

Apollo describes a greenfield expansion designed to scale operations to 12 times capacity, with total investment of INR 300 crores including a land bank of about 2,47,441 square feet adjacent to Unit 3 at the TSIIC Hardware Park, Phase 2, Hyderabad. The facility is planned to support manufacturing, assembly, integration, and testing of weapon systems including Grad rockets, anti-submarine warfare rockets, anti-tank mines, artillery munitions, and similar systems.

This is consistent with the broader strategic shift from subsystems to complete weapons and integration. It is also consistent with the order book number. The presentation reports an order book of INR 14,320 million as on 31 March 2026. In long-cycle defence manufacturing, execution and qualification matter as much as order intake. Apollo positions itself as a Tier 1 supplier and claims a proven track record across DRDO programs, with presence in all missile programs and naval warfare programs.

R&D spend is another indicator of intent. The company states R&D as a percent of revenue in FY26 stood at 8 percent, and an R&D section shows FY26 R&D as INR 725 million with 8 percent. It also states zero attrition in the R&D team during FY26 and highlights development work including a mini torpedo, sensor suite for underwater autonomous vehicles, and FOG-based INS systems.

Ownership of IP and in-house design is positioned as a strategic moat. Apollo says it designs and manufactures systems and weapons using in-house engineering from initial concept through production, with documented requirements and verification records, and with IP retained or assigned under contract terms. In defence contracting, such discipline reduces compliance risk and enables life-cycle support revenues.

Investor takeaways: strong FY26, but watch execution and cash conversion

Apollo Micro Systems ends FY26 with a clear theme: scale-up with integration. Financially, the company delivered record revenue and profit growth, with consolidated revenue up 61 percent, EBITDA up 69 percent, and PAT up 91 percent. Q4 FY26 added another signal, with the highest ever quarter on revenue, EBITDA, and PAT.

Strategically, the business is pushing up the value chain. It is expanding from mission-critical electronics into complete weapons and weapon integration, and adding explosives capability through the IDL acquisition. The portfolio described spans underwater mines, torpedo homing systems, rockets, aerial bombs, navigation systems, and early-stage directed energy weapon subsystems. The planned capacity expansion and continued R&D intensity support this ambition.

For investors, the key questions going forward are practical. Can Apollo execute production ramps while maintaining margins. Can working capital continue to improve as programs shift from development to production. And can the explosives subsidiary stabilize margins and capacity utilization while also serving Apollo’s defence explosive needs. The presentation’s order book, improving ROCE, and lower debt-to-equity are supportive. But the negative operating cash flow in FY26 is a reminder that rapid growth in this sector often demands capital and disciplined conversion.

The company’s own framing is that FY26 was a breakthrough year marked by highest-ever revenue and profitability, completion of the IDL acquisition, progress on licenses, and the receipt of its first export order. If Apollo sustains delivery momentum and improves cash conversion as capacity comes online, the integrated defence platform it describes could translate into a longer runway than a typical electronics supplier.
