Defence

The first analytical act in defence is classification. A titanium ingot maker and a radar-electronics designer are both "defence companies" and should never carry the same multiple. Get the layer wrong and every comparison that follows is wrong.

Value the company by its layer in the chain and its end-user, then underwrite the one variable that actually moves margin: import content falling, and whether the order book is production or development work.

01 — Market Map

Classify twice: by end-user, then by layer.

Companies divide first by end-user exposure — Army, Navy, or Air Force — and second by operational layer: Materials, Components, Subsystems, or complete Platforms. This is not taxonomy for its own sake. A raw-material supplier must be valued on materials-industry metrics, not benchmarked against a complex electronics or subsystem manufacturer.

LayerArmyNavyAir Force
PlatformsTanks, armoured vehicles, artilleryNaval vessels and construction supportFighter aircraft, helicopters, UAV platforms
SubsystemsFire control, missiles, battlefield electronicsTorpedoes, sonar, submarine combat systemsRadars, avionics, missiles, electronic warfare
ComponentsHydraulics, pneumatics, valvesPrecision components, underwater hydraulics, heat exchangers, propulsionActuators, landing gear, pumps, control systems
MaterialsSpecialty steel, aluminium, titaniumSteel and titanium alloys for submarinesTitanium, aluminium alloys, composites
Worked example — one missile, four multiples. A stainless-steel supplier providing low-alloy steel is a materials business. A rocket-motor maker is a component business. A propellant-booster supplier sits at subsystem level. The company making the missile's electronics — its brain — is a design-IP business and earns the highest margin of the four. Same programme, four entirely different valuation frames.
02 — Structure & Economics

Order type decides margin; import content decides the re-rating.

Production orders beat development orders. Development work carries execution risk and thin economics; series production is where margin sits. The mix between the two inside a headline order book matters more than its size.

Payment terms differ sharply by customer. Foreign contracts typically use letters of credit. Advance payments in domestic tenders are essentially unheard of — which is why working-capital days in this sector run at 120–200, far above normal industrials. Where raw materials are supplied by the customer as part of the contract price, or a price-escalation clause exists, the risk profile improves materially.

Watch PSU insourcing. As PSUs internalise low-value assembly and outsource selectively to MSMEs, private suppliers' margin sustainability comes into question. Ask where in the chain the company's work would sit if the PSU chose to bring it in-house.

How the economics vary by layer

MetricPlatform & assemblySystems integrationDesign-IP led
Order book / sales3.5–5.5x3.0–4.2x3.0–4.0x
R&D / revenue3–8%4–6%8–10%
EBITDA margin16–24%19–21%27–30%
Working capital days180–200150–190~120
Exports (% revenue)6–12%5–18%20–25%

The pattern is the point: the highest margin, the lowest working-capital intensity and the highest export share all sit with the most design-IP-intensive layer, and the heaviest capital demands sit with platform assembly. Ranges are indicative across the listed peer set and move each quarter.

Import content by segment — the localisation thesis

SegmentImport contentKey imported subsystemsDirection

03 — What Drives a Winner

IP, white space, and export access.

— 01

Design IP

Owning the design rather than assembling to someone else's is what produces 27–40% EBITDA margins and low working capital. Moving from component supplier to solution provider is the re-rating event.

— 02

High-barrier white space

Titanium, superalloys, energetic materials, aero-engine components — segments that are import-dependent, hard to enter, and where indigenisation policy creates a captive demand curve.

— 03

Export access

Exports diversify away from a single monopsony buyer and carry better payment terms. Private companies already account for the majority of India's defence exports.

The demand backdrop is explicit. The Technology Perspective and Capability Roadmap sets out where procurement is heading: electronic warfare and software-defined radios for the Air Force; ammunition and anti-tank guided missiles for the Army; weapons systems and next-generation destroyers and frigates for the Navy; and remotely piloted aircraft plus EW and communications across all three. Externally, the EU's ReArm Europe programme — over €800bn through 2030 on ammunition, missiles and EW — pulls Indian component, processed-material and radar-electronics suppliers into a second demand pool.

04 — Diligence Checklist

What to answer before underwriting.

  • Layer and end-user. Which layer does this company genuinely occupy, and against which peer set should it be valued? Are Army, Navy and Air Force exposures disclosed separately?
  • Production vs development. What share of the order book is series production versus developmental work, and how does margin differ between them?
  • Import content by product line. What is it today for missiles, radar, avionics — and what is the credible path down? This is the margin and multiple story.
  • New vs legacy programmes. What share of order inflow comes from new programmes versus legacy ones? New programmes signal relevance to the next procurement cycle.
  • Contract clauses. Is there a price-escalation clause? Are raw materials supplied by the customer within the contract price? Is it a yearly contract with customer-borne inflation?
  • Advance and payment terms. What percentage of order value is received as advance, and does the export book use letters of credit?
  • Export vs domestic. Split between exports and domestic PSU/MoD/DRDO work, and how concurrent are repeat orders?
  • Technology transfer. Any ToT arrangements with domestic or international partners, and what do they give away versus acquire?
  • PSU insourcing risk. How sustainable are margins as PSUs internalise low-value assembly and outsource to MSMEs?
  • Tender quality. For high-value tenders, what is the genuine win probability, and how much of the pipeline is above a 50% threshold?
05 — KPIs to Track

What to monitor, quarter by quarter.

KPICalculation / sourceBenchmark or read-through
Order book / salesClosing order book ÷ TTM revenue3.0–5.5x across listed peers; the revenue visibility measure
Order inflowNew orders booked in the periodLumpy — use trailing four quarters, never a single quarter
Production vs development mixOrder book splitProduction-weighted books convert at better margin and lower risk
Import content %Imported input value ÷ total inputsThe direction matters more than the level — falling = margin tailwind
EBITDA marginP&L16–18% at platform/subsystem assembly; 27–40% for design-IP businesses
R&D ÷ revenueP&L disclosure3–10% band; higher spend precedes IP-led margin expansion
Working capital daysInventory + debtors − creditors120–200 is normal here; the trend against peers is the signal
Cash conversion cycleDaysBest-in-class around 90 days; the sector's key differentiator
Advance as % of order valueContract termsHigher advances fund execution and cut working-capital drag
Export share of revenueSegment disclosure5–25% across peers; diversifies away from single-buyer risk
Execution / conversion rateRevenue ÷ opening order bookChronic slippage against guidance is the sector's recurring disappointment
Capex vs order visibilityCapex plan ÷ order bookCapacity built ahead of confirmed orders is the classic value trap
06 — Risks & Red Flags

How the thesis breaks.

  • !
    Execution slippage. Order books convert slower than guided — engine delivery delays being the canonical example. A large book is not revenue.
  • !
    Valuation ahead of earnings. Steep multiples relative to expected growth leave no room for a single missed quarter.
  • !
    Margin dilution from bought-out content. Rising bought-out components and competitive intensity trend margins down even as revenue grows.
  • !
    Single-buyer concentration. The MoD is a monopsony. Budget reprioritisation or programme cancellation has no commercial offset.
  • !
    Working-capital strain. No advances domestically plus 150–200 day cycles means growth consumes cash.
  • !
    FCF constrained by growth capex. Some of the fastest-growing names will not generate free cash for many years — size the position accordingly.
  • !
    Misclassification. Valuing a materials supplier on electronics multiples is the most common and most expensive error in the sector.
