Rating Rationale

­Acuité has reaffirmed its long-term rating of ‘ACUITE BBB-’ (read as ACUITE triple B minus) and short-term rating of 'ACUITE A3' (read as ACUITE A three) on the Rs.198.00 Cr. bank facilities of Annai Infra Developers Limited (AIDL). The outlook is 'Stable'.

Rationale for reaffirmation
The reaffirmation of rating reflects AIDL’s moderation in operating scale supported by order book of Rs.1007.51 Cr. as on 31st January 2026, including new solar EPC projects and recently secured contracts outside Tamil Nadu, provides revenue visibility over the medium term. The rating also factors in the established operational track record of the company, supported by experienced promoters and long-standing relationships with government agencies. The company’s financial risk profile remains healthy, characterised by comfortable leverage, adequate debt-servicing capability and adequate liquidity. However, the rating remains constrained by high working-capital intensity arising from elevated Work-in-progress and retention-linked receivables, and exposure to execution-related delays. The company also remains vulnerable to geographic concentration in Tamil Nadu and an ongoing GST matter, though legal opinion indicates limited financial impact on the credit risk profile of the company.


About the Company

­Annai Infra Developers Limited (AIDL) was incorporated in 2008 and is located in Erode, Tamil Nadu. AIDL is promoted by Mr. Subramaniam Ashok Kumar and his wife, Mrs. Duraisamy Kalaiselvi, having experience of over a decade, in the construction and infrastructure development sector. AIDL is primarily engaged in engineering, procurement, and construction (EPC) activities of water management and irrigation projects, such as the building of dams, laying of pipelines, integrated stormwater drains, wastewater treatment plants, developing drainage systems, lift irrigation, drip irrigation, reservoirs, canals, and installation of irrigation pipelines, among others. It is registered as a Class-1 civil contractor in the states of Tamil Nadu. The client base includes primarily government entities, viz. the Public Works Department (PWD) of Tamil Nadu, Kerala. The company has ventured into a new segment, i.e., solar projects, to grab the demand and to substitute irrigation and water supply contracts.

Key Rating Drivers

Strengths

Experienced management and established operational track record
Annai Infra Developers Limited benefits from a strong promoter group, led by Mr. Subramaniam Ashok Kumar and Mrs. Duraisamy Kalaiselvi, who together have nearly two decades of experience in the civil construction and infrastructure sector. The promoters remain actively involved in day-to-day operations and are supported by an experienced management team with established technical capabilities in executing EPC projects. Over the years, the company has built longstanding relationships with various government departments in Tamil Nadu and Kerala, enabling a stable flow of irrigation, water supply and stormwater management projects. In addition to its established presence in South India, the company has recently started entering new geographies outside its traditional operating region, reflecting the early stages of geographic diversification. Acuité believes that the promoter’s extensive industry experience, strong counterparties, and expanding regional presence will continue to support AIDL’s business profile over the medium term.

Moderation in operating scale albeit comfortable order book position
The company reported a significant moderation in operating scale in FY2025, with total operating income declining to Rs.306.12 crore from Rs.620.21 crore in FY2024, largely due to lower tender availability in Tamil Nadu and weather-related execution delays. Despite the contraction in scale, operating margins remained comfortable at 14.21% in FY2025, compared with 14.52% in FY2024, supported by efficient cost control and long-standing expertise in executing government EPC projects. The Profit After Tax (PAT) margin also remained healthy at 8.58% in FY2025, broadly stable against 8.92% in FY2024, reflecting resilient profitability despite lower revenue. The company recorded Rs 370.75 crore in sales up to February 2026 in the current financial year, indicating improved momentum in ongoing project execution. As of January 2026, the company’s unexecuted order book stood at Rs.1007.51 crore, providing strong medium-term revenue visibility. The order book comprises a diversified mix of stormwater drainage projects, TWAD water-supply schemes, PWD canal works, and expanding solar EPC mandates, with execution timelines spanning the next two years. The company has also begun entering new geographies outside Tamil Nadu, further strengthening its future revenue pipeline. Acuité believes that AIDL will continue to benefit from its long operational track record, established relationships with government bodies, and a comfortable order book position that supports visibility over the medium term.

­Healthy financial risk profile
The company’s financial risk profile remains healthy, supported by steady improvement in net worth, moderate leverage, and comfortable coverage indicators. As of March 31, 2025, the net worth improved to Rs.465.47 crore from Rs.438.83 crore in FY2024, driven by consistent internal accruals and profit retention. Total debt stood at Rs.71.27 crore in FY2025 (comprising Rs.20.75 crore long-term borrowings, Rs.44.07 crore short-term borrowings, Rs.0.27 crore unsecured loans and Rs.6.18 crore of current maturities), compared with Rs.89.33 crore in FY2024, reflecting reduced reliance on external borrowings and stronger internal funding capability. As a result, gearing improved to 0.15x in FY2025 from 0.20x in FY2024, indicating a strengthening capital structure. TOL/TNW also improved to 0.30x in FY2025 from 0.42x in FY2024, reflecting limited dependence on external liabilities relative to net worth. Coverage metrics remain comfortable, with the Interest Coverage Ratio (ICR) at 4.81x in FY2025 compared with 5.90x in FY2024, while the Debt Service Coverage Ratio (DSCR) stood at 1.74x in FY2025 against 2.65x in FY2024. Although these ratios moderated due to lower operating profits, they remain healthy and indicate adequate cash flow sufficiency to service debt obligations. Overall, Acuité expects the company’s financial risk profile to remain healthy over the medium term, supported by stable profitability, an improving capital structure, absence of major debt-funded capex, and a declining debt profile.


Weaknesses

Intensive working capital operations:
The company’s operations remain highly working-capital intensive, reflected in a Gross Current Asset (GCA) cycle of 569 days in FY2025, significantly higher than 260 days in FY2024, primarily due to elevated work-in-progress (WIP) levels and retention-linked receivables inherent to EPC contracting. Inventory days (WIP) increased sharply to 256 days in FY2025 from 101 days in FY2024, as substantial project expenditure was incurred toward year-end while the corresponding billing was recognized only in subsequent quarters, creating a timing mismatch. Debtor days also rose to 66 days in FY2025 from 49 days in FY2024, driven by milestone-based billing and procedural delays in departmental certifications typical of government-funded projects. Creditor days increased moderately to 65 days in FY2025, compared with 42 days in FY2024, providing only a partial cushion against the higher working-capital intensity. Overall, the company’s working-capital cycle remains stretched due to high WIP levels and elongated receivable timelines associated with irrigation, water-supply and stormwater EPC projects. However, the fund-based bank-limit utilisation remained moderate at 75.45% for the six months ended January 2026, indicating ongoing reliance on bank limits to support execution. Going forward, faster bill certification, timely release of dues, and normalization of WIP levels will be critical for improving working-capital efficiency.

Exposure to execution-related risks, tender-driven nature of the business, high geographic and segment concentration risks
AIDL remains exposed to execution risks inherent in EPC contracting, where delays in site access, departmental clearances and monsoon-related disruptions can affect project timelines. The business is predominantly tender-driven, with revenue visibility closely linked to government awarding cycles and budget availability—making order inflows sensitive to policy-driven volatility. The company also faces high geographic concentration, with a major share of revenues historically arising from Tamil Nadu, exposing operations to region-specific risks. Segment concentration remains significant as well, with the order book largely comprising water supply, irrigation and stormwater management projects, though the recent addition of solar EPC mandates has begun to broaden the mix. While entry into solar projects and new geographies provides early signs of diversification, dependence on a few regions and segments continues to be relatively high. Acuité believes that a sustained scale-up in solar EPC and gradual geographic expansion will be essential to mitigate these vulnerabilities over time. Nonetheless, these risks are partially offset by the promoters’ nearly two decades of experience in the EPC sector, which supports stable execution capabilities and long-standing relationships with government departments.

  • ???????Deterioration in the financial risk profile
 
Liquidity Position
Adequate

The company’s liquidity position remains adequate, supported by healthy net cash accruals of Rs 29.82 crore in FY2025, providing sufficient coverage against annual repayment obligations of Rs 12.55 crore. NCA’s are expected to range between Rs.39-49 Cr. over the medium term which would comfortably meet the expected repayment range of Rs.6.18-5.00 Cr. As of March 31, 2025, AIDL maintained unencumbered cash and bank balances of Rs 12.22 crore, while the current ratio stood at 6.48x in FY2025 (from 4.60x in FY2024), aided by a strong net-worth base, though working capital continues to remain absorbed in WIP and government-linked receivables. Fund-based working-capital limit utilisation averaged around 75.45% for the six months ended January 2026.
