- **[PRINCIPLE] Long Gestation R&D Investment** (POSITIVE, Trend: NEW_TREND): While COGS remains high at 70% due to R&D-heavy projects, a new trend of margin improvement is expected as large-scale production orders (like QRSAM and Akash NG) begin execution. (1 new trend across 1 signal, 1 leading indicator)
  > we have been spending around 9% to 10% of our outlay, topline, as R&D expenditure since our company is a -- bread and butter is R&D.
- **[PRINCIPLE] Order Book Execution Visibility** (POSITIVE, Trend: ACCELERATING): The order book remains robust, providing multi-year revenue visibility as the company integrates IDL Explosives to pursue larger, high-value defense tenders. (1 steady, 3 accelerating across 4 signals)
  > Looking ahead, we expect revenue to grow at least at a CAGR of 45% to 50% over the next three years, which has always been our, guidance since few quarters, solely by the core business
- **[TREND] Atmanirbhar Bharat Self-Reliance Push** (POSITIVE, Trend: STEADY): The company is maintaining a high-growth trajectory, projecting a 45-50% CAGR over the next three years as it transitions from a subsystem provider to a full-spectrum weapon systems OEM.

  > before this financial year end, at least some three companies we are going to, we are going for due diligence.

### Risk Assessment

- **[CATALYST] DAC Large Order Approvals** (POSITIVE): The risk is easing as the company has successfully completed the final combat trials for the multi-influence ground mine. While the RFP was delayed past March 2025, management now expects the order to flow within the current financial year. (1 easing, 4 stable)
  > the last phase of the limited explosive trial is conducted, which is a combat trial. And it has been a very successful trial... we are expecting this order to flow in this financial year.
- **[METRIC] Indigenization Percentage per Platform** (POSITIVE, Risk: MODERATE): The trajectory is EASING. The acquisition of IDL Explosives allows for vertical integration, which management explicitly states will improve control over input costs and allow for bulk procurement at competitive rates. (1 easing)
  > right now it's around 70% our material consumed, right? ... Till such a time, the similar COGS levels would be maintained actually because predominantly most of the projects that we are addressing are, typically R&D projects.
- **[METRIC] Revenue per Employee Productivity** (NEGATIVE): The risk is intensifying as the company has increased its expansion plans from 5.5x to 13x the current facility size, leading to a significant rise in employee costs and upcoming depreciation hits. (1 intensifying)
  > from the current, size of the facility we have contemplated for an expansion of, 5.5 to 6.5 times. Now with the addition of the other new facility... up to 12x to 13x times, the facility will increase. Proportionately the manpower also will be increasing actually.
- **[METRIC] Working Capital Days and Cash Conversion** (NEUTRAL, Risk: MODERATE): The risk is stable but transitioning to execution. Unit-2 is starting operations in Q2 FY26, and Unit-3 Phase-1 is underway with a Rs. 150 crore allocation. This expansion is intended to reduce working capital by bringing testing in-house. (1 stable)
  > from the current, size of the facility we have contemplated for an expansion of, 5.5 to 6.5 times. Now with the addition of the other new facility... up to 12x to 13x times, the facility will increase. Proportionately the manpower also will be increasing actually.
- **[PRINCIPLE] Government Dependence and Payment Cycles** (NEGATIVE, Risk: HIGH): The risk is STABLE but the context is improving due to macro tailwinds. While specific DAC clearances for the Moored Mine are not updated here, the company is diversifying its product profile into 'new classes of advanced weapon systems' to reduce dependency on any single product line approval. (1 stable, 1 high-severity)
  > It is not in our control, sir. It depends on availability of Raksha Mantri, various other officials who are part of this thing, not in our control... if it slips it may go for another DAC meeting.
- **[PRINCIPLE] Long Gestation R&D Investment** (POSITIVE, Risk: LOW): The risk is intensifying as R&D spend is expected to cross the traditional 6-8% threshold this year, with INR 100 crore allocated for future R&D. (1 intensifying, 2 easing, 2 stable)
  > we have been spending around 9% to 10% of our outlay, topline, as R&D expenditure since our company is a -- bread and butter is R&D. Unless we do R&D, we cannot sustain.
- **[PRINCIPLE] Order Book Execution Visibility** (POSITIVE): The risk is easing as several programs are transitioning from the unpredictable development phase into full-fledged series production, which allows for better raw material planning and lower working capital cycles. (1 easing, 2 stable)
  > during a full-fledged production phase, there is a defined production cycle and critical planning in terms of the sourcing of the raw material... which will effectively reduce the overall cycle of the working capital.
- **[TREND] Private Sector Entry and Joint Ventures** (NEGATIVE): The risk remains STABLE as the company has officially signed the Share Purchase Agreement for 100% of IDL Explosives for INR 107 crore. While the acquisition is a strategic move for vertical integration, the immediate financial impact of absorbing a previously loss-making entity persists until operational synergies are realized. (2 stable, 1 intensifying)
  > Apollo Defence Industries Pvt Ltd (ADIPL)... has entered into a Share Purchase Agreement to acquire 100% equity stake in IDL Explosives Ltd for a total consideration of INR 107 crore, in an all-cash transaction.
- The risk is INTENSIFYING as the company has moved from 'due diligence' to a formal 'all-cash' acquisition of IDL Explosives. Integrating a 64-year-old legacy company into a high-growth electronics firm requires significant management bandwidth and cultural alignment. (5 intensifying, 2 high-severity) (NEGATIVE, Risk: HIGH)
  > Akshay: Okay sir, and sir, my second question is about the promoter pledge, so when -- by when are we clearing the promoter pledge? Sai Kumar: Okay, see like everything goes well, no, like -- We are we are working towards it in few quarters, we should be coming out.

### Scenario Analysis

- The first-order adoption of Industry 4.0 automation across its massive 12x facility expansion directly lowers its cost-to-serve and improves manufacturing precision. This operational efficiency enables the second-order development of high-margin, AI-driven autonomous systems like anti-drone swarms and seeker electronics, which are critical for modern edge-AI defense workloads. Ultimately, this leads to a third-order structural shift where Apollo moves from a labor-intensive component maker to a high-tech platform leader in the AMCA and indigenous missile programs, capturing sector leadership through data-to-productivity conversion. (POSITIVE)
  > And also, we are doing one automation, complete all factories now we are going for automation, we are almost implementing Industry 4.0 standard we are implementing. Wherein the management can see the complete machinery, how machinery is utilized, how manpower is working... complete machinery utiliza
- The Iran conflict scenario triggers an immediate surge in demand for Apollo’s missile subsystems and naval mines as India prioritizes maritime and border security. This first-order revenue tailwind transitions into a second-order operational advantage as the company’s 'Make-in-India' focus allows it to bypass the logistics bottlenecks and import delays affecting competitors. Ultimately, this results in a third-order structural shift where Apollo evolves from a component supplier to a Tier-1 defense OEM, capturing higher margins and a larger share of the national defense budget. (POSITIVE)
  > QRSAM one program is going for bulk production. And another program is Akash NG also is going for a few hundred numbers. And if you see these two programs, our major contribution is there... missile technology side if you see, we have good contribution, subsystem-wise if you see 63% of our contribut
