Enviro Infra Engineers Ltd Q2 FY2025 Concall Summary

Key Takeaways

• Revenue and profit surged, cash flow turned negative: Revenue grew ~78% YoY and net profit more than tripled, but operations consumed cash as unbilled revenue built up and payables shrank by ~₹105 crores.
• The order book is pivoting hard toward wastewater: Wastewater treatment projects will make up 60–65% of the mix this year, a structural shift management expects to persist.
• Margins are defended by in-house design and energy plays: Management attributes ~25% EBITDA margins to process-design expertise and waste-to-energy initiatives, and sees no downside to that level.
• The working-capital cycle is an outlier, and the explanation is thin: A 40-day cycle and 45–50% return ratios drew analyst questions; management declined to compare itself to peers and pointed to fast execution and vendor payment ability.
• What to watch next quarter: Whether the negative operating cash flow reverses as promised, the pace of new order wins against the ~₹2,000 crore full-year target, and any clarity on the gap between tax provision and cash tax paid.

Financial Performance

• Top-line explosion: Revenue rose ~77.82% YoY in Q2 and 50% in H1, driven by execution across a 22-project, ~₹1,960 crore order book.
• Profit conversion even stronger: Net profit grew >189% in Q2 and 106% in H1, reflecting operating leverage on the in-house execution model.
• Cash flow flipped negative: Cash from operations turned negative because unbilled revenues increased and trade payables contracted by ~₹105 crores, a combination management called temporary and expects to reverse in coming quarters.
• Creditor days compressed sharply: The creditor cycle fell from 120 days in FY24 to 75 days, which alone drove a ~₹105 crore cash outflow.
• Unbilled revenue buildup: Revenue is booked as unbilled when a project stage is incomplete or a GST invoice has not yet been raised; the slowdown in the government funds-release cycle, especially for JJM projects, has stretched the cash conversion timeline.
• Tax provision unexplained: An analyst flagged a ₹25 crore tax provision against only ₹4 crore of cash tax paid; management deferred the question to the CFO for a later clarification.

Sanjay Jain: "If you just recall the contents of my speech, I had clarified that cash flow from operations has been negative. Basically, since March till November, there has been a bit slow down on the government spending. And that is 100% true."

Order Book & Bid Pipeline

• Order book stands at ~₹1,960 crores across 22 projects, with execution expected to accelerate in the coming quarters.
• Wastewater is the new center of gravity: The order book has entirely changed and is now more aligned toward wastewater treatment projects (WWTPs); for FY25, WWTPs will assume a 60–65% ratio, and management expects that tilt to continue.
• Fresh order target: The company expects a fresh order book of around ₹2,000 crores for the current financial year and is "hopeful that we can easily achieve it."
• AMRUT-2 pipeline: Bids invited in the last month under AMRUT-2 total ₹3,500–4,000 crores, and the company is interested and bidding.
• Industrial effluent opportunity: With industrialization, common effluent treatment plant opportunities are increasing; the company is interested in common plants for industrial areas, not individual effluent treatment plants.

HAM Projects

• Bareilly (operational): Achieved commercial operation date 71 days ahead of schedule on 18 July 2024; the first quarterly annuity, due 17 October 2024, has been released.
• Mathura (underway): Effective date declared from 29 November 2024; physical progress has commenced in full swing.
• Saharanpur (financial close): Term loan sanctioned by HDFC Bank on the date of signing the concession agreement (27 September); the scheduled declaration date is 26 January 2025, and management is trying to get the effective date declared before that.

Sanjay Jain: "We are ahead of time again and trying our level best to get the effective date declared before the actual scheduled date."

Margin Structure & Competitive Edge

• In-house design as a moat: Both Sanjay Jain and management are chemical engineers; process designing is a core domain capability that lets the company propose the most economical and viable solutions.
• Waste-to-energy lifts capex and opex margins: Sustainability initiatives, including waste-to-energy, drive higher margins on both the capital and operating sides.
• Execution stays in-house: The company does not depend on subcontractors, which management says yields better quality, lower cost, and ahead-of-schedule completion.
• Life-cycle cost bidding wins on margin, not just price: In the Kota project, the company was ~₹10 crores higher on capital cost versus peers but won as L1 on life-cycle cost because a solar plant lowered power consumption, delivering better margins than peers.
• Margin outlook: Management expects to continue maintaining similar EBITDA margins of around 25% and sees no downside.

Management: "It is a combination of that in-house designing, the initiative which we are taking through sustainability and waste-to-energy which are driving further higher capex and opex margins for us, our advanced technological initiatives, our execution capabilities. So, all these combining are giving us these EBITDA margins are somewhere around 25%. So, that way we are confident and we are sustaining those margins."

Working Capital & Return Ratios

• Working-capital cycle is unusually short: The company maintains a ~40-day cycle, far below the 90–100 day industry norm, which management attributes to fast execution and good margins that keep the company cash-flow positive.
• Return ratios are an outlier: An analyst noted return ratios of 45–50% versus a peer benchmark of ~25% and asked how that is possible. Management declined to compare: "Boss, I cannot comment on others, how they are doing. I am managing this company and we are able to make payments to our vendors."
• Working-capital gap claim: Management stated that no working-capital gap has built up in the books.
• Banking limits: The company is targeting working-capital limits of ₹1,000 crores and expects to achieve that; one new banker is expected to join, taking the total multiple-banking arrangement to up to 10 banks.

Sanjay Jain: "Boss, I cannot comment on others, how they are doing. I am managing this company and we are able to make payments to our vendors."

Balance Sheet & Capital Allocation

• No major capex ahead: The company does not foresee any major gross block or major capex going forward.
• IPO proceeds earmarked for working capital: Funds from the equity issuance will be used as and when required for working capital, performance bank guarantees, and project execution.
• Other income to rise: Additional FDRs will accrue interest that will be reflected in other income.
