Working capital and operating cash flow stretch during the half year.

Management explained that cash flow was impacted by the longer export operating cycle (up to 9 months), higher activity-driven inventory and receivables, and piled-up GST input tax credits from high RM costs and capex; borrowings should moderate as working capital normalizes.

Extent of raw material price pass-through lag to OEMs and gross margin impact.

Pass-through indexation operates on a 1-month lag for key domestic OEMs; the RM price impact caused a 2.5% contribution margin dip in Q2, but no further prospective degradation is expected as price hikes take effect.

Key themes

Export recovery and non-auto expansion

How the narrative shifted

Class 8 truck export boom: Earlier confusion over EPA '27 has been resolved with a clear compliance path (non-compliance penalty option), strengthening the bullish thesis.
EV ramp with GM/Stellantis: The escalation is pushed out. The narrative shifted from 'on track for ₹200-250 Cr this year' to 'ramping but slower than previously guided, peaking next year.'
Non-auto diversification: Wind and aero are providing tangible, quantified growth, moving from aspirational to concrete execution.
Margin recovery via cost pass-through: The specific 16.5% margin guidance was downplayed. The narrative now focuses on 'margin expansion' from export mix rather than meeting a specific guided number.
Capex-driven capacity expansion: FY27 capex program on track at ₹281 Cr H1, full year guided at ₹350-450 Cr; FY28 outlook premature but continuity expected at similar broad range.
Working capital normalisation narrative: Acknowledged the elevated cash conversion cycle explicitly but tied it to operational growth, framing it as a temporary liquidity stretch rather than a structural issue.
Europe and new customer diversification: The narrative is data-backed now (20%+ UK growth), shifting from a passive 'growing strong' statement to a concrete performance update.
Domestic demand moderation in H2: This is a new, cautious thread acknowledging headwinds in the domestic market, which was previously undifferentiated.

Operational commentary

Export share rebounded to ~30% of revenue in Q2FY27 (from ~25% last year), led by strong schedules from key US customers including Cummins and Navistar.
Non-auto segment revenue reached 35%-37% of total revenues, driven by wind energy and aerospace expansions.
Stellantis hybrid/ICE business billing is ramping up to ₹150-175 Cr in FY27 compared to ₹50 Cr in FY26, with peak volume timeline visible by H2FY28.
Phase 3 capex of ₹70-80 Cr in wind energy is underway to scale segment revenue past ₹500 Cr annually.
Aerospace division is expanding with ₹30-40 Cr capex targeting revenue scaling from ₹100 Cr+ in FY27 to ₹200 Cr in future years.
International subsidiaries posted profitable growth with China growing 25-30% in INR terms and the UK growing 20%+ in INR terms.
