1) Standalone EBITDA in Q2 FY26 & H1FY26 declined primarily due to one-time expenses related to the discontinued operations at the Ambad manufacturing plant (other than VRS), which includes discarding of fixed assets and Consolidated EBITDA in Q2FY26 & H1FY26 declined further due to lower sales in Goel Scientific Glass Works Limited. 2) The Company had introduced a Voluntary Retirement Scheme (VRS) for the eligible workers at its Ambad, Nashik plant. In H1FY26, the Company entered into a Memorandum of Settlement with the Bhartiya Kamgar Sena (BKS), the registered trade union representing these workers. The settlement, including related professional fees, resulted in an expense of ₹6.61 crores, which is an exceptional item. 15 Particulars (₹ Crs)H1FY26H1FY25YoY%H1FY26H1FY25YoY%Net Sales188.5 181.1 4.1%202.9 207.5 -2.3%EBITDA26.5 28.3 -6.3%18.0 29.4 -38.8%EBITDA (%)14.1%15.6%8.9%14.2%EBIT17.7 19.9 -11.1%8.3 20.2 -59.0%PBT10.8 19.5 -44.6%1.1 19.4 -94.6%PAT8.0 14.2 -43.7%-1.4 13.8 -109.9%N

Note

1) Process System had a revenue degrowth due to a significantly lower opening order book as of 1 July 2025 that would be available for execution during Q2 FY26. Some of the key customers’ order got delayed and their execution is deferred to Q3 FY26 due to various reasons and hence the sale in Q2 FY26 got impacted. Encouragingly, fresh order bookings in H1 FY26 were substantially higher than last year, a considerably large part of these order is due for execution Q3FY26, order booking for H2FY26 looks promising which will positively impact our H2FY26 sales. 2) In Pharma Packaging, the temporary decline in performance during H1FY26 was primarily due to gaps in operational efficiencies at the plant. We have since addressed this by appointing seasoned industry professionals to lead operations, which has already started improving output. In parallel, order bookings across key product categories have strengthened significantly. This positive momentum is already visible in Q2FY26 performance,
