Key themes

DaVinci adoption, market share gains, and capacity expansion

How the narrative shifted

• Record EBITDA margin driven by P3 operating model: Margin dip is attributed to exogenous headwinds (Middle East war, non-indexed commodities) and new public-company costs, not to P3 model weakness.
• Order book provides FY28 revenue visibility: Reduced airtime and no reaffirmation of the specific INR124bn coverage claim, though new wins imply continued strength.
• Exports emerging as growth accelerator: Tariffs and global macro are newly cited as challenges, but the long-term export ambition is unchanged; 70-30 split between intercompany and third-party disclosed.
• DaVinci DCx disrupts suspension market: Narrative strengthened with specific proof points (new product variant, new customers, capacity utilization >90%), reinforcing disruption claim.
• CAFE 3 and BS7 regulatory tailwinds: Downside adjustment to content-per-vehicle expectations from prior bullish framing; addressed only briefly in Q&A.
• Capacity expansion to capture volume and technology growth: Capex range increased from prior implied levels (INR140 crore announced was for 2 plants); higher and more specific guidance.
• Deepening OEM relationships and technology leadership: More granular wins cited, including white-space spark plug order, strengthening the technology leadership story.
• Balance-sheet strength and capital efficiency: No change in framing; M&A option newly disclosed as potential use of cash.

Operational commentary

• DaVinci DCx platform momentum: secured multiple new application wins across existing customers and added four new customers on conventional and DCx platforms; introduced DCx32 (32mm piston) targeting A and B segment vehicles, significantly expanding addressable market.
• Completed fitment and performance benchmarking of Mechanical Adaptive Ride Damping (MARD) technology with a leading domestic OEM, entirely developed and validated in India.
• Clean Air & Powertrain: secured a spark plug order from one of India's largest passenger vehicle OEM, marking entry into a new white space; won a new PV exhaust program with a leading domestic OEM, a cold end assembly program for a global OEM's CNG platform, and an emissions aftertreatment program for a leading domestic CV manufacturer.
• Export wins: maiden ART export order from a leading European all-terrain vehicle manufacturer; heat shield order from Tenneco America demonstrating global competitiveness.
• Customer recognition: Innovation and Performance Award from Mahindra, Technology and Innovation Award from Daimler India Commercial Vehicles, and Ride Performance of 2026 Award from The Economic Times.
• Capacity utilization: ART above 90%, Clean Air & Powertrain above 80%; new ART plant in western India announced with ~₹70 Cr investment to meet demand surge and GST-driven volume growth.
• Exports rose to slightly over 7% of total revenue in Q1FY27; export order book mix currently ~70% intercompany (Tenneco to Tenneco) and ~30% third-party OEMs.

Analyst Q&A

• Q. What is the size of the newly won spark plug order from the large PV OEM?

  We haven't released the value for that yet. We will do that at the right time when we have solidified the revenue value.

• Q. Why did Clean Air & Powertrain growth of ~10% lag industry growth?

  The served addressable market must exclude EV volumes and the large Japanese PV OEM where we are not present; after these adjustments, our 9.6% growth is slightly better than the apples-to-apples market.

• Q. Can you break down the margin decline between the two segments?

  We do not disclose margins at the BU level. The margin delta year-over-year is mainly due to costs of being a newly listed public company and non-indexed commodity inflation, partially recovered.
