The procurement & commodity lens — steel, zinc & aluminium (the margin swing factor), subcontract & erection, conductors, hardware & galvanizing inputs; terms, supply risk and the hedge, cash & continuity move for each input.
Steel, zinc & aluminium are the margin swing factor — 5 inputs sit at elevated risk with FY27 commodity-cost pressure flagged. Hedge and lock them, stretch payables to help fund the 214-day receivable cycle (₹61 Cr of cash), and consolidate the top tier before prices spike.
4 of 4 headline metrics improving vs prior · still off target: Contribution Margin 11.0% vs 13.0%, Revenue (FY26) ₹2,792 Cr vs ₹3,200 Cr, Cash Conversion Cycle 74d vs 60d
Steel — angles, plates & tubes (towers / poles) & Subcontractors — erection, civil & foundations & Aluminium & conductors (ACSR / AAAC) & Zinc — special high-grade (galvanizing) & Power, stores & MRO carry medium+ risk — steel & zinc are the biggest margin swing factor, and a fixed-price EPC contract lets a price spike compress the thin 4.4% EBITDA margin (FY27 pressure flagged).
₹61 Cr of cash stays in the business by moving DPO from 166d to the 175-day target on ₹2,455 Cr of spend — the deliberate WC lever that partly offsets 214 debtor days, no hit to margin.
Steel — angles, plates & tubes (towers / poles) (₹1,450 Cr) and Subcontractors — erection, civil & foundations (₹320 Cr) are 72% of spend — concentrating volume earns rebates and priority allocation.
₹2,455 Cr of steel, zinc, aluminium, subcontract & galvanizing inputs runs through 6 input lines — steel the single biggest line and the key margin driver (fixed-price EPC; steel/zinc spikes compress the thin margin, FY27 pressure flagged). This view turns that into two moves: a ₹61 Cr cash release from stretching payables, and a hedge-and-secure plan for the 5 commodity-exposed inputs whose price could squeeze the 4.4% EBITDA margin.
Two inputs are 72% of spend — the negotiation priorities.
Each card: spend, reliability and the specific move.
