I'm Arvind Nanda here, newly appointed Executive Arvind Nanda: Chairman, also promoter of the company, of Interarch. Good afternoon, everyone. Thank you for joining us on the Interarch Building Solutions carnings conference call to discuss our operational and financial performance for the second quarter of the half-year ended 30 September 2026. We would like to first thank Ambit for the continued support they have been giving us over the last many years, and especially after we have become a listed company and continue to host our camnings calls. We trust that everyone has had the opportunity to go through our financial results and investor presentation. Both are available on the stock exchanges and our website as well. Before we begin the discussion on the quarter, let me give you a brief overview of our business. Atthe core of Interarch's business is the design, manufacture, and execution of pre-engincered buildings, or PEBs as we call them, and more and more also pre-engineered structures, which can cater to a much larger market than just a pure building, as we will see when we grow and when we are talking about the other parts of our business, you will see that there are many other types of steel structures required in the fast-growing Indian economy. These are all custom-engincered steel structures manufactured in controlled factory environment, normally designed and engineered by us as well, manufactured and then taken to site in more or less complete condition except the final assembly is done in a nut and bolt assembly at site. Everything else has already been done in our state-of-the-art plants located at different locations. And this enables very fast construction timelines, optimized material utilization, because all the work is done in our plant under very controlled conditions and highly automated lines and highly skilled people. Page 2 020 Interarch Building Solutions Limited November 06, 2026 This gives us consistent quality and improves cost efficiency. Making PEBs an increasingly preferred solution across industries such as manufacturing, logistics, warehousing, retail, aviation, infrastructure, data centers, and, in the coming years, high-rise commercial buildings, and then going on to any kind of high-rise or institutional building also, like schools, colleges, malls, stadiums, airports. Everything will gradually get converted into steel. It has already been done, but more and more it will become general usage. Interarch differentiates itself with its integrated turnkey business model, which offers end-to- end solutions through the entire project lifecycle, from in-house design and engineering to the manufacture of structural components using HR plates, coils, and coated coils for roof and wall cladding, followed by on-site erection through nut-and-bolt assembly. Interarch executes every stage of the project under a single-responsibility framework. This integrated approach gives customers greater certainty on project quality, timelines, overall exccution, and cost. So he is dealing with one company as an overall one-stop shop. For a whole building, like a product, unlike the traditional method where the customer has to deal with three or four different parties and bear the brunt of any defect, loss or problem created by any of these contractors, hie has to bear the brunt. Each project is engineered to meet specific technical and operational requirements, whether for manufacturing, logistics, high-rise industrial buildings, commercial structures, or specialised applications such as data centres. Our ability to deliver highly customised solutions reflects the strength of our engineering capabilities, which remain a key pillar of our business, as they should be in any pre-engineered business. Robust engincering not only enhances structural performance and safety, but also improves manufacturing efficiency, execution reliability, and long-term quality, as well s safety values for our customers, and very, very efficient and time-bound execution. Our customer base includes several leading Indian and multinational companies that rely on Interarch for their mission-critical industrial and commercial infrastructure requirements. I would say that hardly any nltinational or Indian company which has not worked with Interarch in the last 25 to 40 years and has not used our building produc [Showing first 8,000 characters — download PDF for full document]
