I N D E X 06 THE WABAG GROUP 15 FINANCIAL PERFORMANCE 23 ORDER BOOK ANALYSIS MANAGEMENT COMMENT “Crossing Rs. 20,000 crores in order book for the first time ever is a defining milestone for WABAG, achieved alongside robust top-line growth and strong profit momentum. In H1 this year, we secured two landmark “Mega” orders, a “Mega” SWRO project that marks our entry into Kuwait, and a “Mega” deal with RIL for one of the largest desalination plants in India at Jamnagar. Together with our entry into the UAE through Ajman, expansion in Europe with Donauinsel Water Works, and key municipal orders from BWSSB and DJB, these wins showcase the trust our clients place in us for their most complex, technology-intensive projects, which will continue to be our focus area. Strong margins and better working capital management also helped us deliver our 15th back-to-back quarter of positive net cash, which crossed Rs. 1,100 crores excluding HAM, another major milestone for WABAG. With Order Book at more than four times of our annual revenue and a healthy bid pipeline, we are well positioned for the years ahead. Rising water security needs and the push on treated water reuse & desalination both for municipal and industrial sectors, are strong tailwinds for the sector. We will stay selective, focusing on securing more “Large” and “Mega”, technology-led projects, Rajiv Mittal and deliver growth and margins in line with our strategic targets” Chairman & Managing Director PERFORMANCE HIGHLIGHTS H1 FY26 H1 FY27 INR Mn Q2 FY26 Q2 FY27 INR Mn 20.3% 20.7% 29.3% 19.9% 20.0% 23.3% 18,870 15,685 10,002 8,345 2,161 2,608 1,506 1,947 1,205 1,445 848 1,046 REVENUE EBITDA PAT REVENUE EBITDA PAT ▪ Strong Order Book of ~INR 202 Bn → Robust Revenue Visibility; Order H1 FY2026-27 Performance Metrics Intake of ~ INR 52 Bn in H1 FY27 ▪ Secured multiple orders from RIL: 13.8% 10.3% 16.3% • ‘Mega’ order for Desalination and Remineralisation plants EBITDA MARGIN PAT MARGIN RoE • Repeat ‘Medium’ order for ETP at DAGEGC, Jamnagar Driven by EP, International, Driven by debt control & improved Creating long term Shareholder Industrial and O&M Projects operating margins Value ▪ Debuted in Kuwait with the official signing and commencement of contract for the 'Mega’ 60 MIGD (~ 272 MLD) SWRO order from MEWRE INR 11,442 101 20.5% ▪ Announced ‘Large’ order for the expansion of the Donauinsel Water NET CASH NWC DAYS RoCE Works in Vienna, Austria Driven by Efficient Cash Driven by Operational Driven by Asset Light Business ▪ Net Cash positive for the 7th year running (15th consecutive quarter), Management Efficiency Model reflecting the quality of order book and cash management *Net Cash including HAM Projects - INR 10,361 Mn WABAG GROUP 100 YEARS YOUNG & STRONG YEARS CENTURY 2.0 Pioneering the Next 100 Years 1996 2010 2019 2026 Foundation of VA VA TECH WABAG Ltd.
