1. Opening Hook

Tenneco Clean Air India just had its best year ever—18.8% EBITDA margin, 12.3% value-added revenue growth, zero debt. They’ve doubled their growth rate versus the prior three years, expanded order book to ₹12,400 Cr, and their freshly listed stock has outpaced the BSE Sensex since November’s IPO. Q4 alone did 17.5% revenue growth and 17.6% EBITDA growth—all while geopolitical cost pressures were supposedly “elevated.” Which is interesting, because nobody actually quantified what that meant until the Q&A began working it out.

2. At a Glance

Value Added Revenue (FY26) – ₹4,918 Cr, up 12.3% YoY. Q4 alone hit ₹1,405.8 Cr, +17.5%. Two business units: Clean Air & Powertrain (+5.5%) and Advanced Ride Technologies (+19.7%).

EBITDA & Margins – ₹925.5 Cr FY26 (+13.5%), margin 18.8%—the company’s highest ever. Q4 EBITDA ₹257.3 Cr at 18.3% margin. Expanded 450 basis points since FY24.

PAT – ₹604.4 Cr FY26 (+9.3%), but this includes a “one-time labour code charge.” Q4 ₹166.8 Cr, +18.8%.

Order Book – ₹12,400 Cr lifetime orders, 14–20% of it exports. Provides “100% visibility of FY 2028 internal revenue target.”

Capital Efficiency – ROCE jumped to 94% (from 57% in FY25). Fixed asset turnover 9.6x. Cash conversion cycle: negative 23 days (collecting faster than paying).

Balance Sheet – Debt-free. Net debt-to-equity negative 0.4. Generated cash flow at 58% of EBITDA despite ₹115 Cr capex.

Clean Air Reality Check – Grew only 5.5% despite 18% industry CV growth. Management blamed OEM mix shifts (lower-end SUVs, more electric vehicles at a European customer), not competitive loss. New Japanese OEM entry opens ₹1,300–₹1,400 Cr addressable market via CAFÉ 3 & BS7 norms starting 2028.

3. Management’s Key Commentary

On exports being the next growth vector:

“Our exports are coming in way stronger than our current level of exports. Currently we’re at about 5% to 6%, but our order book is somewhere between 14% to 20%.”

(Translation: Exports are 5%, but the order book says it’s going to be 2–3× bigger. That gap between “current” and “committed” is either a confidence statement or a test of credibility.)

On the new suspension technology (DaVinci DCx):

“This is a total game changer and disruptive to the conventional mechanical dampers which still dominate over 90% of passenger vehicles in India.”

(The claim: 90% of Indian passenger vehicles still use conventional dampers. If true, that’s a massive wedge. If the DaVinci takes even 10% of that, it’s material.)

On the Clean Air entry into a major Japanese OEM (CAFÉ/BS norms):

“We’re hoping that once we enter the panel, our growth will increase quite a bit, and we’ll be able to do so with equal or better margins simply because it is a high-tech product.”

(Translation: We weren’t in the biggest PV OEM in India. Now we are. Hope it works, margins stay the same or better. “Hoping” is the word that does the heavy lifting here.)

On capacity and new plants:

“We are making disciplined capacity investments. Alongside our previously announced Clean Air facility in North India in Q3 FY26, we are now setting up a new greenfield Advanced Ride Technologies plant in West India. Together, these projects represent an announced capex of approximately ₹1,400 million.”

(₹140 Cr capex split across two plants. At a 1:3 capex-to-revenue ratio, that’s ₹420 Cr in steady-state revenue expected from these two facilities alone.)

On the “transient” cost pressures:

“This margin progression from 14.3% in FY24 to 18.8% in FY26 reflects the cumulative benefits of our P3 operating model, driven operational discipline, improved costs absorption and timely commercial actions.”

(Translation: Margins went up despite geopolitical costs. The P3 framework got the credit. “Timely commercial actions” means prices were hiked or cost recovery clauses were invoked; the margin expanded because costs were passed on faster than they were incurred.)

On the bearings entry:

“We haven’t still mentioned the actual value because this is just a significant entry, let’s call it a strategic entry into this customer, but at some point, we will publish the exact numbers when they become available.”

(Translation: A bearings order was won from a major Japanese OEM. The size isn’t being disclosed. Could be ₹10 Cr or ₹100 Cr. Watch this space.)

On the IPO and stock performance:

“Our issue was oversubscribed 61.8x, with qualified institutional buyers subscribing 174.8x their allocation. Since the listing, our stock has delivered returns that outperform both the BSE Sensex and the BSE Auto index.”

(174.8x subscription from QIBs is extraordinary. The stock has beaten Sensex and Auto indices since listing. Not a statement about future returns, but proof that the market validated the narrative at listing.)
