Motherson Sumi Wiring India Q4 FY26 PAT up 1%

Key takeaway from the March 2026 quarter

Motherson Sumi Wiring India reported a modest year-on-year increase in profit for the March 2026 quarter, even as revenue rose sharply on the back of higher demand and capacity additions. The company posted a net profit (PAT) of ₹167.30 crore in Q4 FY26, up 1.44% from ₹164.93 crore in Q4 FY25. Revenue from operations increased 32.88% to ₹3,334.62 crore from ₹2,509.50 crore over the same period. The update positions the company as one of the auto ancillary names that benefited from strong OEM offtake during the quarter. But the financials also showed that profitability did not rise in line with sales growth. That gap was attributed to cost pressures and the timing of price pass-through.

Q4 FY26 numbers: profit up, margins under watch

In Q4 FY26, profit before tax (PBT) stood at ₹211.71 crore, down 3.63% from ₹219.69 crore in Q4 FY25. EBITDA was reported at ₹274 crore, up 1.1% from ₹271 crore a year earlier. The combination of higher revenue and relatively flat EBITDA indicates margin pressure during the quarter. The company flagged elevated copper prices and a lag in cost pass-through to customers as key reasons profitability remained under pressure despite higher volumes. These inputs matter in wiring harness manufacturing because copper is a material cost driver.

FY26 performance: revenue crosses ₹10,000 crore mark

For the full year FY26, Motherson Sumi Wiring India reported a net profit of ₹625.18 crore, up 3.19% from ₹605.86 crore in FY25. Revenue from operations rose 23.15% to ₹11,477.58 crore in FY26 from ₹9,317.67 crore in FY25. EBITDA for the year was reported at ₹1,061 crore, up 6.4%. The company said it delivered its highest-ever quarterly and annual performance and crossed the ₹10,000 crore revenue milestone for the first time. Chairman Vivek Chaand Sehgal also noted that the company maintained a debt-free balance sheet.

What drove the revenue jump

The company attributed the FY26 and Q4 growth to strong demand from OEMs and the ramp-up of greenfield facilities. For a wiring harness supplier, this typically translates into higher build schedules at automakers, new programme wins scaling up, and new plants stabilising output. The company also stated that it continued supplying to nine of the top ten selling passenger vehicle models in India during the quarter. That footprint matters because it ties the supplier’s revenue trajectory to high-volume nameplates and ongoing model refresh cycles.

Profitability constraints: copper prices and pass-through timing

Despite the strong sales print, profit growth remained muted in Q4 and FY26. The company cited elevated copper prices and a lag in passing costs through to customers. This is a common friction point in auto component contracts, where raw-material price movements do not always reflect immediately in customer pricing. In such periods, reported margins can compress even when volumes are improving. The Q4 pattern, with revenue up over 32% but EBITDA up around 1%, highlights this operating reality.

Electric vehicle contribution disclosed

Motherson Sumi Wiring India disclosed that electric vehicle-related revenue contributed 8.6% in Q4 and 6.6% for the full year. These disclosures help investors track how quickly EV-linked wiring programmes are scaling within the overall harness portfolio. The figures also provide context on how much of the revenue base is already influenced by EV production trends, without implying that the business is EV-dependent.

Business profile and ownership structure

Motherson Sumi Wiring India operates in the Automobile and Ancillaries sector and is categorised under the Auto Ancillaries industry. The company is a full-system solutions provider to OEMs in the wiring harness segment in India. It is a joint venture between Samvardhana Motherson International (SAMIL) and Sumitomo Wiring Systems (SWS). The JV structure is relevant because it combines local scale and customer relationships with global wiring harness expertise.

Stock market reaction and seasonal return note

Following the results-related news flow, shares of Motherson Sumi Wiring India fell 0.87% to close at ₹38.92 on the BSE. Separately, the article data also noted that the stock has delivered positive returns in April in each of the last five years (5 out of 5). While seasonality does not explain quarterly earnings, such historical return patterns are often tracked by market participants alongside near-term catalysts like results.

Why this update matters for auto ancillary tracking

The results show a clear separation between revenue momentum and profitability growth in the near term. For investors tracking auto ancillaries, the key variables highlighted are OEM demand strength, capacity ramp-up through greenfield facilities, and raw-material movements that affect pass-through cycles. The EV revenue share disclosure adds another measurable indicator for monitoring product-mix evolution across quarters. The combination of a debt-free balance sheet statement and record revenue provides additional context on financial positioning, even as margin pressure remains a headline item.

Conclusion

Motherson Sumi Wiring India closed FY26 with revenue of ₹11,477.58 crore and Q4 revenue of ₹3,334.62 crore, while PAT growth remained low due to copper cost pressures and pass-through timing. Investors are likely to track how quickly cost recovery reflects in margins in subsequent quarters, alongside the company’s ongoing ramp-up of greenfield facilities and OEM demand trends.
