Over to the management team. Krishna Rana: Thank you, Vinay. Good afternoon everyone and thank you for joining us today for Platinum Industries Limited’s Post Earnings Conference Call for the first quarter of Financial Year 2027. I am Krishna Dushyant Rana, Chairman and Managing Director of Platinum Industries Limited and I am joined by our Chief Financial Officer, Mr. Ashok Bothra. Let me begin by thanking all our employees, customers, business partners, stakeholders and shareholders for their continued trust and support. At Platinum Industries, we remain focused on building a strong and differentiated position in the PVC and CPVC additive industry, with a clear emphasis on higher-value products, capacity expansion, product innovation and increasing our presence across both domestic and international markets. The first quarter of FY27 was a period of transition and capacity ramp- up for the company. On a consolidated basis, revenue from the operations stood at ~ INR 108.9 crores, compared with INR 115.4 crore in Q1 FY26. Profit before tax stood at ~ INR 15 crores while profit after tax was INR 11.1 crore. While the consolidated top line was impacted by the ongoing transition and the ramp-up phase, we remain encouraged by the underlying business opportunities and importantly by the progress made on our capacity expansion initiatives. The focus during the quarter was on strengthening our manufacturing platform, improving our product mix and preparing the company for the next phase of growth.

Partial commercial operations of the CPVC facility that was 12,000 tonnes per annum commenced in August 2025, while the remaining capacity of 48,000 tonnes per annum of PVC, CPVC, lubricants andother facility commenced commercial production effective from 21 May, 2026. The expanded facility adds ~ 60,000 tonnes per annum of capacity, comprising 24,000 tonnes of lead-free in PVC, 24,000 tonnes of CPVC and 12,000 tonnes of lubricants and others. With the full ramp-up of this facility, our total capacity in India is expected to scale towards 85,000 tonnes plus per annum. This includes stearates capacity of 6,000 tonnes per annum, which is likely to commence commercial production in September/October 2026. This expansion is strategically important because it strengthens our presence in premium non-lead additives and CPVC additives. While also providing us with greater operating leverage. We expect the benefits of this capacity to become increasingly visible as utilisation ramps up over the coming quarters. Another significant milestone is the progress of our manufacturing facility in Egypt. We remain committed to commence commercial production before 31 December, 2026. The facility involves a total investment of ~ INR 68 crores and will have a production capacity of 60,000 tonnes per annum. Egypt is a strategically important project for Platinum Industries. Its location provides us access to attractive international markets, including duty-free access to the United States through Qualified Industrial Zones and free trade access to key South American markets. This will enable us to establish a cost-competitive manufacturing and export platform closer to important global polymer additives markets. We believe the Egypt facility can significantly strengthen our international footprint and improve our product and geographic mix.More importantly, it is expected to become a meaningful growth and margin driver as we move into FY28. Our strategy continues to be focused on increasing the contribution from value-added products, particularly lead-free and speciality stabilisers and CPVC-related products. The shift towards lead-free solutions is supported by increasing customer preference for more sustainable products, while CPVC continues to offer an attractive opportunity in the pipes and fitting segment.

We are also continuing to work towards new product introductions like the Oleo Chemicals Derivatives and speciality chemicals, which has commenced the sales in Platinum Oleo Chemicals Private Limited. Looking ahead, we remain confident about the long-term growth opportunity for Platinum Industries. FY27 is an important year for us because we are moving from a phase of capacity creation towards a phase of capacity utilisation and operational scaling. Our key priorities for the year are:  Ramp-up of expanded Palghar facility;  Completion and commissioning of the Egypt facility;  Increasing utilisation of our new capacities;  Improving the contribution of higher-value and lead-free products;  Expanding our domestic and export customer base and;  Maintaining strong focus on operating efficiencies and financial discipline. We believe these initiatives will create a stronger and more diversified business platform and position the company well for sustainable growth over the medium to long term. We continue to remain focused on our previously articulated growth ambitions, while ensur [Showing first 8,000 characters — download PDF for full document]
