Shares of Cummins India cratered 10% to ₹4,253.20 on November 5, after the company's September-quarter results, released the prior evening, fell short of Wall Street expectations on nearly every key metric. The selloff erased roughly ₹5,000 crore in market value in a single session, raising pointed questions about whether the margin squeeze is temporary or structural. Cummins India Sheds 10% in a Day After Profit Drops Despite Revenue Growth — Is the Margin Squeeze Temporary or a Sign of Deeper Trouble?
Shares of Cummins India plunged 10% to ₹4,253.20 on November 5, after September-quarter results released the previous evening revealed a stark disconnect between top-line growth and bottom-line performance. For shareholders who rode the stock up through a strong fiscal 2026, the question is whether rising costs are a one-quarter headache or a longer-term drag on returns.
• Revenue Grew, but Profits Fell Sharply
Cummins India reported consolidated revenue of ₹3,301 crore for Q2 FY27, a 4.1% year-on-year increase, while profit after tax fell 18.5% to ₹507 crore.
Operating profit declined by 27.1% year over year , meaning the company spent significantly more to generate only marginally higher sales. Standalone profit before tax came in at ₹601 crore with a margin of 18.5%, and net profit margin fell to 14.4%. Compare that to Q2 FY26, when the company posted a 42% year-on-year profit jump to ₹638 crore on 28% sales growth. The deceleration is unmistakable.
• Commodity Costs and Freight Are Eating Margins Alive
Consolidated gross margins contracted by 350 basis points (3.5 percentage points) year over year to 33.5% — meaning for every ₹100 in revenue, the company kept ₹3.50 less before overhead. Sharp increases in steel, pig iron, aluminium, copper prices, along with elevated freight costs and labour shortages at suppliers, squeezed profitability.
Cummins India has implemented price hikes to counter rising raw material costs, but a full margin recovery is expected to lag.
• Cash Reserves Shrank, Adding Financial Pressure
Cash and cash equivalents fell to ₹166 crore as of September 30, 2026, from ₹500 crore at March 31, 2026 — a 67% drawdown in just six months, reducing the company's financial cushion precisely when cost headwinds are intensifying.
• The Data Center Boom Hasn't Been Enough to Offset the Squeeze
While domestic operations are benefiting from surging data center demand, export sales remain constrained by geopolitical disruptions in the Middle East.
Data centers grew to 40% of the power-generation segment's sales in the prior quarter , a structural positive. But volume alone cannot mask margin erosion when input costs rise faster than selling prices. Until price hikes fully flow through — likely not before Q3 or Q4 — investors should expect profitability to remain under pressure.
