The full read
Star Cement’s latest earnings call leaves investors with a difficult math problem. Management slashed its non-cement margin guidance to 7-8%, a sharp reversal from the 20% target set just three months ago. They offered no explanation for the drop. At the same time, the company is accelerating its capital spending. The FY28 capex budget is now ₹1,500 crore, up from the previous ₹1,000 crore estimate, while FY27 spending is also rising to ₹600-700 crore. These moves come alongside a projected ₹40-50 crore decline in subsidies and persistent cost pressures from coal inflation and the West Asia crisis. While management expects these costs to normalize, the combination of lower margins and higher spending creates a tighter cash flow profile. The company’s Rajasthan and Bihar expansion remains the primary growth story, with commissioning still set for early FY29. For now, the open question is whether the margin compression is a temporary blip or a structural shift in the business.
