• FY26 Revenue of INR 7,548 crore (+20% YoY) is highest annual turnover since listing

• FY26 Gross margin of 10.5% improved versus FY25 Gross Margin of 10.1%. We expect Gross margins for EPC businesses to stabiliz e around 8-10% (depending on Turnkey/BOS),

and O&M at ~20%. Q4FY26 gross margins were strong in International EPC due to 3 projects achieving commissioning ahead of bud geted costs

• FY26 Operational EBITDA reached INR 444 crore (5.9% margin), a growth of 53% YoY. EBITDA margins are more reflective of stead y-state levels. Annual recurring overhead of

INR 349 crore remains in-line with FY25 levels

• Q4FY26 Reported PAT of INR 142 crore is highest quarterly PAT since listing. Reported FY26 PAT was negatively impacted by exceptional items (primarily related to Litigation

matters reported during Q2-Q3) leading to a Loss of INR 296 crore
