Classes & the full value ladder

Ten sub-industries, one climbing margin story — with two sharp exceptions

Reading this report's own company research from the most commodity-priced to the most engineered layer of the entire stack — wafer to substation — produces a real, evidence-based margin gradient, not an indicative illustration. It is not perfectly monotonic, and the two exceptions matter as much as the pattern itself.

Margin and engineering difficulty climb together across most of the combined stack — except at the two rungs this report flags explicitly below. Uses real, reported margin figures from this report's own thirty-five-company research; see Notes for methodology.

Exception one: a low-visibility layer holding outsized value

Semiconductor packaging (OSAT) sits, on a naive value-chain reading, below a branded systems integrator — it never puts its own name on a finished server. Yet a company holding one of India's few operational packaging lines can plausibly hold more durable pricing power than a much larger, more visible AI-server assembler, precisely because packaging capacity is nationally scarce and government-incentivised, while server-assembly capacity is not.

Exception two: a high-visibility layer holding no listed value at all

Precision cooling (CRAC/CRAH units) and data-centre-grade UPS — the exact equipment behind the globally recognisable APC, Vertiv and Stulz brands — are supplied in India almost entirely by unlisted multinational subsidiaries. A public-markets investor cannot buy this specific, highly visible layer of the stack on the Indian exchanges today. This is the mirror image of the OSAT exception above: one is a hidden layer holding real value; the other is a visible layer holding none, at least not on the public markets.

The ten sub-industries, at a glance

LayerWhere the margin evidence pointsCompanies in §9
Chip / IP design servicesUndisclosed at the segment level everywhere; a structurally undercounted layer (§8)LTTS, Cyient, Sasken
Semiconductor packaging (OSAT)Indicative ~20-24%; the low-visibility, high-value exception aboveKaynes Technology, CG Power
Server / AI-hardware assemblyThin (~10-14%) and reported to be compressing industry-wide, generation over generationNetweb, Dixon, Syrma SGS
GPU cloud / compute consumptionCurrently loss-making or single-contract- concentrated; too immature to place on the ladder with confidenceE2E Networks, ESDS Software Solution
Power equipment (transformers, switchgear, grid tech)Most consistently expanding/scarce of any physical layer — Hitachi Energy India's 7%→9.3%→15.4% climbVoltamp, Hitachi Energy India, ABB India, GE Vernova T&D, Siemens Ltd, Siemens Energy India, Schneider Electric Infrastructure
Backup power / batteries~11-14%, thin DC-specific evidenceAmara Raja Energy & Mobility
Cooling~8-9%, genuinely mixed/volatile — this report's one physical-layer exception to the "engineered = expanding" ruleBlue Star, Voltas, Thermax
Cabling~10%, stable-to-strong, real product differentiationSterlite Technologies, Polycab, KEI Industries, Finolex Cables
Civil / EPC constructionThinnest and most consistently compressing layer in this report's entire universe — ~5-6%Techno Electric & Engineering, KEC International, Kalpataru Projects International, Ahluwalia Contracts
Data-centre-adjacent telecom & conglomeratesNot meaningfully placeable — DC exposure is a rounding error inside a much larger, differently-driven businessRailTel, Anant Raj, Bharti Airtel, Tata Communications, Adani Enterprises, L&T
