How did Tenneco's Q4 earnings compare to the prior year?

PAT grew 19% YoY in Q4 FY2026, while value-added revenue rose 17.5% in the quarter. The full year saw value-added revenue growth of 12.3%.

What is the significance of the 18.8% EBITDA margin?

It is the highest-ever EBITDA margin for the company. This indicates improved profitability from the mix shift toward value-added products.

The order book now covers revenue targets through FY2028, providing multi-year visibility. This de-risks the company's ongoing capacity expansion investments.

18.8% Highest-ever EBITDA margin achieved in Q4 FY2026.

What's new

PAT grew 19% YoY in Q4; value-added revenue rose 17.5% in the quarter and 12.3% for FY2026.
EBITDA margin hit a record 18.8%, the highest since the company's listing.
Order book now covers revenue targets through FY2028.

Why this matters

Double-digit growth in both quarterly and annual value-added revenue suggests Tenneco's higher-margin product mix is scaling. A record margin on a mid-cap industrial name shows pricing power or cost discipline, or both. The FY28 order-book coverage de-risks near-term capacity expansion plans.

What we're watching

Whether the 18.8% margin holds as new capacity comes online.
The next phase of capacity expansion and its capital cost.

The full read

Tenneco Clean Air India delivered a clean set of results. Q4 PAT grew 19% YoY, value-added revenue rose 17.5% in the quarter, and for the full year, that revenue line expanded 12.3%. The standout number is the 18.8% EBITDA margin, a record for the company. This isn't a one-quarter pop.
