Revenue from operations grew by 16% year-on-year to Rs. 239 crores, while EBITDA increased by 22% to Rs. 60 crores, with EBITDA margins improving to 25.3%. On the business front, our Domestic business delivered a strong performance during H1FY27, registering growth of 33%, driven by increased traction across sectors and sustained demand. Our International business, on the other hand, witnessed a de-growth of 14% during the period. Given the project-driven nature of this business, which may result in variations in execution and revenue recognition across quarters, we believe its performance is best evaluated on a full-year basis. Meanwhile, our Fenestration business recorded robust growth of 82% during H1FY27. Our order book stood at Rs. 957 crores as of 30th September 2026, providing healthy revenue visibility going forward. We continue to see opportunities across domestic façade projects, international façade product supply and the premium fenestration segment. Our integrated capabilities position us to address evolving customer requirements, while our emphasis on long-standing customer relationships and execution discipline remains central to converting business opportunities into sustainable growth. We will also continue to focus on expanding our international presence and increasing the contribution of value- added manufacturing to our business. The backward integration initiative through the in-house Glass Processing Unit (“GPU”) at our Vile Bhagad facility is progressing as planned, with commissioning expected by August 2027. The facility is expected to improve EBITDA margins by ~100–150 basis points over time, while reducing dependence on external processed-glass suppliers and enhancing supply-chain control. This investment will further strengthen our manufacturing capabilities, improve control over quality and lead times, and support the delivery of customised, value-added solutions. For FY27, we remain confident of achieving significant revenue growth over FY26, with EBITDA margins expected to remain broadly in line with the previous financial year. As we progress through the year, our priorities remain focused on disciplined project execution, strengthening our operating capabilities and pursuing growth opportunities while maintaining profitability. We believe these initiatives will support the next phase of growth and enable us to create sustainable long-term value.” About Glass Wall Systems (India) Limited Glass Wall Systems (India) Limited is a premier turnkey façade specialist, delivering integrated design, engineering, manufacturing and installation for commercial, residential and institutional projects.
