### Management Credibility

- **[CATALYST] Indian Water Companies Expanding Internationally** (POSITIVE, MET): The company confirmed the divestment of three European subsidiaries, which has resulted in reduced 'other expenses' in the current quarter. (2 met across 2 tracked commitments)
  > Predominantly, it will be India to start with. We will also be looking at Southeast Asia and maybe very selectively the African opportunities also we will look at.
- **[CATALYST] Namami Gange Program Phase 2 and Tributary Expansion** (POSITIVE, MET): The company achieved Commercial Operation Date (COD) for the Kolkata HAM project, which is its first contract with the National Mission for Clean Ganga (NMCG). (1 in progress, 1 met across 2 tracked commitments)

### Risk Assessment

- **[CATALYST] Indian Water Companies Expanding Internationally** (NEGATIVE, Risk: MODERATE): The risk is stable as international exposure is a deliberate strategy for growth. Management notes that while geopolitical disturbances exist (e.g., oil prices, Bangladesh turmoil), projects funded by multilaterals remain secure. (3 stable, 2 intensifying)
  > Overseas 12,622 [INR Mn] ... 50% RoW [Rest of World]
- **[CATALYST] Semiconductor and Pharma Manufacturing Water Demand** (POSITIVE): EASING. The company is successfully diversifying into high-tech industrial sectors like Solar, Semiconductors, and Green Hydrogen, which reduces reliance on municipal budgets. (1 easing)
  > Our recent order from RenewSys, Hyderabad marks a major milestone... essential for wafer cleaning and conditioning in solar cell manufacturing... Similar requirements are emerging across Green Hydrogen, Data Centers and Semiconductor Fabs.
- **[METRIC] MLD Capacity Installed and Under Execution** (NEUTRAL): The risk is STABLE; while major projects like Perur and Ras Tanura (80% complete) are on track, the Indosol Solar project faced a 6-7 month delay due to government land reallocation. (1 stable)
  > Indosol Solar order has been slower than expected... there was a slowdown of about 6 to 7 months because of the change of land.
- **[METRIC] Net Working Capital Days** (POSITIVE, Risk: MODERATE): The risk is easing as working capital days have improved to 110 days, and the company has transitioned to a net cash position of Rs. 705 crores, a 16x improvement over five years. (5 easing)
  > 101 NWC DAYS ... Driven by Operational Efficiency
- **[METRIC] O&M Revenue as Percentage of Total Revenue** (POSITIVE, Risk: MODERATE): The risk is easing as the company is successfully building its recurring revenue base, with O&M now making up 43% of the order backlog, providing high predictability for future earnings. (2 easing, 3 stable)
  > 82% EPC 18% O&M
- **[METRIC] Order Book Value and Book-to-Bill Ratio** (NEUTRAL): This risk persists as INR 12,636 Mn remains in the 'Framework' category, specifically for Libya projects where Euro-denominated Letters of Credit are still awaited. (1 stable)
  > Key Framework Contracts: Libya STP, Bomba MED Libya; Amount: 12,636 Mn. # Contracts wherein Advance Monies / LC awaited, not taken in Order Intake
- **[METRIC] PAT Margin and Return on Equity** (NEGATIVE): The risk is INTENSIFYING as 'Other Expenses' increased sharply this quarter, largely driven by forex movements and ESOP accruals. (1 intensifying)
  > But largely, it is forex because of the kind of movement that has happened in the exchange rates period-over-period.
- **[PRINCIPLE] EPC Versus HAM Versus BOT Business Model Impact** (NEUTRAL, Risk: MODERATE): Execution risk is stable but remains a core concern for large-scale projects like the Perur desalination plant; however, management is shifting toward 'EP' (Engineering & Procurement) only models to avoid construction-related delays. (1 stable)
  > The risks and uncertainties relating to these statements include... time and cost over runs on contracts
- **[PRINCIPLE] Government Capital Expenditure Dependence** (NEGATIVE, Risk: HIGH): While municipal projects remain a core focus (70% of backlog), the risk is stable as the company is successfully diversifying into industrial sectors (Power, O&G) and international markets to reduce reliance on the India municipal cluster. (4 stable, 1 high-severity)
  > Municipal 19,925 [INR Mn] ... 80% Municipal
- **[PRINCIPLE] Working Capital Intensity from Government Project Execution** (NEUTRAL, Risk: MODERATE): Certain large projects in the 'Framework' category are delayed because the company is still waiting for advance payments or Letters of Credit (guaranteed payment documents), meaning this work cannot yet begin. [EXECUTION]
  > # Contracts wherein Advance Monies / LC awaited, not taken in Order Intake
- The risk persists as INR 12,331 Mn remains in the 'Framework' category (not yet in active backlog), with management still awaiting full LC documentation for Libya projects. (2 stable, 2 intensifying, 1 easing) (NEGATIVE, Risk: MODERATE)
  > Forex Loss/(Gain) (270) [9M FY'26]
