We are pleased to share that Diffusion Engineers Limited has received significant orders in the last two quarters, further strengthening our order book and enhancing revenue visibility. Our healthy order book of over Rs. 170 crore driven by strong demand for Roll Press Rolls for the cement sector and heavy engineering applications reflects the confidence that customers place in our engineering capabilities, product reliability, and long-standing industry relationships. These developments position us well for sustained growth in the coming quarters.

With new capacities scheduled to come online in FY26E and the completion of our ongoing capex, we are targeting to double our topline in the medium to long term. We also expect EBITDA margin expansion, supported by economies of scale, improved operating leverage, and an enhanced product mix driven by higher-value manufacturing.

Looking ahead, with a robust order book, healthy demand across core sectors, and our ongoing operational initiatives, we are confident of delivering sustainable growth and improved profitability in the coming quarters. I extend my sincere gratitude to every member of the Diffusion family, our valued clients, creditors, bankers, financial institutions, and all other stakeholders. Your trust and support continue to inspire us to strive harder and achieve greater milestones.

Thank you for your continued faith in Diffusion Engineers”
