Analysis: I G Petrochemicals Limited

Growth thesis

I G Petrochemicals is India's largest producer of phthalic anhydride (PAN), with a 275,000-tonne capacity across five plants and the second largest globally. The business sells 80-85% of output within a 200-300 km radius of its manufacturing site, with exports typically 10-15% of volume. The company earns its money on the spread between PAN and ortho-xylene feedstock, plus by-product sales of maleic anhydride and benzoic acid, which flow almost entirely to EBITDA. In Q1 FY27, revenue rose 30% year on year to ₹625 crore, and EBITDA margin expanded to 19.2% from 2.7% in the year-ago quarter, although FY26 as a whole was depressed at 6.7% due to inventory losses and one-time mark-to-market charges. Competition is limited: imports have been reduced to 30,000-40,000 tonnes from over 100,000 tonnes earlier, and an anti-dumping duty of $40/tonne on Chinese PAN and $140/tonne on Korean PAN took effect in August 2026 for five years.

The economics persist because of a structural cost advantage. The company covers 80-90% of operating costs through by-product credits, uses waste heat for 85-90% of its energy needs, and runs a localized distribution network that minimizes logistics expenses. This allows it to earn $100-120 per tonne above the market PAN-OX spread consistently, which management stated on the May 2026 call. The anti-dumping duty adds a further protective layer, and the company's low-cost position means it remains profitable even in downcycles. Ten-year average spreads of $200-220 per tonne suggest the current $250-300 level is not exceptional, but the company's own operational efficiency provides a durable edge.

The inflection is the commissioning of the 75,000-tonne plasticizer plant and the debottlenecked DEP unit. The plasticizer plant reached mechanical completion in March 2026, and commercial production is targeted before September 2026, with a ramp to 2,000-2,500 tonnes per month in the balance of FY27, implying 15,000-20,000 tonnes for the year. In FY28, management guides to 50,000-65,000 tonnes, which would bring utilization to 70-80% of nameplate. The CBG plant at Raichur is slated to start in the October-December quarter of FY27, and the DEP plant now has 12,000 tonnes capacity after debottlenecking, with 8,000 tonnes of production targeted in FY27. By mid-2028, assuming this ramp is achieved, PAN volumes could grow to 230,000-240,000 tonnes (from 200,000 guided in FY27), and total revenue at normalized prices is projected at ₹3,000-3,200 crore, up from about ₹2,000-2,500 crore in FY27 depending on pricing. The plasticizer plant alone could add roughly ₹500-600 crore of net revenue at full capacity, and at 60-75% utilization, the blended EBITDA margin should move toward 15-16%.

Management's walk has been mixed but is improving. The plasticizer plant was originally expected to commission by December 2025, but mechanical completion was pushed to March 2026, and commercial production is now slated for August-September 2026, a clear slippage. However, the company met its FY26 PAN volume guidance of around 200,000 tonnes, and it delivered on the promise to convert euro-denominated debt to rupees and prepay part of it, reducing forex exposure. The dividend recommendation of ₹5 per share for FY26 signals confidence. On the latest call in August 2026, management maintained the FY27 PAN volume target of 200,000 tonnes and provided concrete plasticizer ramp numbers, suggesting a commitment to execution. The Q1 FY27 EBITDA of ₹120 crore, which exceeded the full FY26 figure of ₹130 crore, lends credibility to the near-term profitability trajectory.

The earnings path is quantified by the ramp schedule. If the plasticizer plant achieves 15,000-20,000 tonnes in FY27 and 50,000-65,000 tonnes in FY28, and if PAN spreads remain at $200-250 per tonne, the company should sustain an EBITDA run rate of ₹120 crore per quarter or higher, translating to ₹400-500 crore annually. The key falsifier is the pace of plasticizer ramp-up; any delay beyond the guided September 2026 start would compress FY27 revenue and could spill into FY28. Another watchpoint is the global maleic anhydride oversupply from China, which could pressure by-product prices and reduce the spread advantage. The tension between a weak FY26 (PAT ₹23 crore) and a strong Q1 FY27 (PAT ₹71 crore) is explained by inventory losses and mark-to-market effects, which are non-operational. The structural story is intact, and the 18-24 month outcome hinges on disciplined execution of the plasticizer ramp and maintenance of the cost-led spread advantage.
