Star Cement is the largest cement producer in Northeast India, with a 78% trade share in that region as of Q4 FY26, selling OPC and PPC cement along with clinker, AAC blocks, and RMC. The company's economics are exceptional: FY26 EBITDA per ton reached INR1,738, up from INR1,245 in FY25, and Q4 FY26 alone delivered INR1,871 per ton. This performance is driven by a dominant position in a niche market with only a handful of players (Dalmia is second, plus 3-4 smaller unlisted firms), a cost advantage from FSA coal from Coal India (78.5% of fuel mix) and captive power, and a strong trade network that commands pricing. The company also benefits from government incentives, though these are declining, with FY27 subsidies guided at INR145-150 crore versus INR184 crore in FY26.
The persistence of these economics rests on barriers that are real but not permanent. Management estimates an entry barrier of 3-4 years for new competition, built on dealer relationships, brand loyalty, and logistics advantages in a terrain where diesel costs and rail connectivity matter. However, competitors like Shree Cement, Ambuja, and JK Lakshmi have announced entry into the Northeast, so the moat is time-limited. The company's ability to hold EBITDA per ton at INR1,500-1,700 for the next 2-3 years depends on pricing rationality, which management expects given the nuanced trade market. Outside the Northeast, in West Bengal and Bihar, volumes are growing (Q4 FY26 outside Northeast sales were 4.91 lakh tons versus 3.74 lakh tons a year earlier), but profitability is lower, making the core Northeast franchise the profit engine.
The inflection is the expansion into North India and Bihar, with a clear 18-24 month picture. For FY27, management guides 10-12% volume growth on a base of ~5.3 million tons, implying ~5.8-5.9 million tons. Capex is raised to INR600-700 crore for FY27 and INR1,500 crore for FY28, up from prior guidance of INR500-600 crore and INR1,000 crore respectively. The Bihar grinding unit (2 million tons) is expected to commission in Q1/Q2 FY29 (April-September 2028), which is at the edge of the 18-24 month window from now. The Rajasthan clinker and grinding project (5 million tons total) is targeted to start around September 2028, subject to approvals by October 2026. By mid-2028, the company should have volumes around 6.5-7 million tons, with the Bihar plant just starting and Rajasthan still under construction. Non-cement revenue (AAC, RMC) is targeted at INR150 crore with 7-8% margins, up from INR43 crore in FY26.
Management has a strong track record of delivering on promises. In the Nov 2025 call, they guided FY26 volume of 5.4-5.5 million tons and reiterated it in Feb 2026; 9M volume was ~4.0 million tons, so Q4 needed ~1.3 million tons, which they achieved. They promised Silchar grinding unit commissioning by January 2026, and it was commissioned in February 2026 as per the May 2026 call. EBITDA per ton guidance of INR1,650-1,700 for FY26 was reiterated and delivered at INR1,738. Incentive run-rate of INR220-250 crore for FY26 was repeated and 9M booked ~INR200 crore, on track. They have now raised capex guidance for FY27 and FY28, indicating confidence. Funding is via internal accruals, keeping net debt/EBITDA below 1.5x. The only notable slip is the Bihar plant timeline, initially expected first half of FY28, now pushed to Q1/Q2 FY29, but management attributes this to land and approvals.
The quantified earnings path: FY27 volume ~5.8-5.9 million tons, EBITDA per ton ~INR1,600-1,700, giving EBITDA of ~INR950-1,000 crore. FY28 volume could grow another 10% to ~6.4-6.5 million tons, with similar per-ton EBITDA, giving ~INR1,050-1,100 crore, plus non-cement revenue adding ~INR10-12 crore EBITDA. The key assumptions are that Northeast pricing holds despite new entrants, cost inflation (fuel, packing bags) is absorbed, and the Bihar plant commissions on time. The single most important watchpoint is whether the company can maintain EBITDA per ton above INR1,500 as competition intensifies and subsidies decline. The tension is that Q1 FY27 EBITDA will be under pressure from cost inflation (INR250-300 per ton impact) and subsidy reduction (INR40-50 crore per quarter), but management expects normalization by June 2026. If they hold per-ton margins, the growth story is intact; if pricing breaks, the thesis weakens. The falsifier is a sustained drop in Northeast EBITDA per ton below INR1,300 or a delay in Bihar commissioning beyond FY29.
