Diffusion Engineers reported robust financial results for Q4 FY25, with revenue increasing by 38.55% YoY to ₹102.45 crores. EBITDA, excluding other income, grew by 82.55% YoY to ₹14.70 crores, and the EBITDA margin expanded by 346 basis points to 14.35%. For the full year FY25, net revenue reached ₹335.20 crores, a 20.51% YoY increase, while EBITDA grew 21.12% YoY to ₹47.08 crores, with a margin of 14.04%. Profit after tax for FY25 stood at ₹36.04 crores, up 17% YoY, with a PAT margin of 10.75%.

The company is undertaking a significant capex of ₹100 crores to double its manufacturing capacity, with new facilities expected to be operational by the end of FY25. This investment includes approximately ₹70 crores for a heavy engineering unit in Nimji and ₹30 crores for a unit at B33 MIDC. Management anticipates reaching 80-85% capacity utilization within the next 2-3 years, maintaining an asset turnover ratio of around 3x. This expansion is crucial for meeting growing demand and enhancing capabilities across all three business segments.

Diffusion Engineers operates across three main product baskets: heavy engineering, welding and anti-wear consumables, and wear plates and wear parts, with each contributing almost equally to revenue. While the company does not disclose segment-wise EBITDA margins, management indicated that anti-wear and welding consumables generally offer higher margins compared to wear plates/parts and heavy engineering. The strategy involves growing the heavy engineering and wear parts business faster than consumables, while also focusing on increasing exports and service offerings to improve overall margins.

The company has expanded its global footprint, exporting to over 30 countries and maintaining subsidiaries and partnerships in Singapore, Turkey, Philippines, UK, and Malaysia. A UK-based associate company, LSN Diffusion Limited (21.5% owned), manufactures thermal spray powders, which are high-performance products complementary to Diffusion's offerings. The company maintains a strong R&D focus, spending approximately 1% of its revenue on DSIR-certified labs, which is critical for product innovation and meeting the increasing performance demands of core industrial customers.

The company's working capital days remain around 90-95 days, attributed to the long manufacturing cycles (6-9 months) and payment terms (90-100 days) inherent in the heavy engineering sector. IPO proceeds were strategically utilized to reduce working capital, which contributed to a reduction in interest costs. Additionally, the company has invested free cash flow in mutual funds, demonstrating prudent financial management post-IPO.

Diffusion Engineers is actively pursuing sustainability initiatives, including monitoring energy and fuel consumption, tree planting, and planning to install a 1.1 megawatt captive rooftop solar plant at its Nimji unit. The company is also expanding its industrial services, offering critical breakdown and repair services, kiln alignment, and other solutions. Management expects service revenue to become a significantly larger part of the business going forward^⏳, acting as a strategic 'door opener' for other divisions and enhancing customer relationships.
