Rating Rationale

­Acuite has reaffirmed its long-term rating of ‘ACUITÉ BB-' (read as ACUITE double B minus) and the short-term rating to  'ACUITÉ A4’ (read as ACUITE A four) on the Rs. 2130.00 Cr. bank facilities of Sterling and Wilson Private Limited (SWPL). The outlook is ‘Stable’. ­Acuite has assigned its short-term rating to  'ACUITÉ A4’ (read as ACUITE A four) on the Rs. 250.00 Cr. bank facilities of Sterling and Wilson Private Limited (SWPL).    Rationale for Rating The rating reaffirmation reflects the strong parentage of SWPL and company’s average financial risk profile. SWPL, a part of the Shapoorji Pallonji Group, operates across multiple business verticals including MEP services, substations and transmission lines, O&M services, and hybrid energy solution. However, the rating remains constrained by SWPL’s weak operating performance and its significant exposure to loss-making subsidiaries and stretched liquidity position. Going forward, the company’s ability to improve its operating performance while improving its financial risk profile and liquidity will be a key monitorable.

Key Rating Drivers

Strengths

­Strong Parentage, long track record of operations and diverse product profile Sterling and Wilson Private Limited (SWPL) is a part of Shapoorji Pallonji Group and is promoted by Shapoorji Pallonji and Company Private Limited (SPCPL) and Mr. Khurshed Daruvala. Established in 1927 as Wilson Electric Works, SWPL was incorporated in 1974. SWPL is an electro-mechanical engineering company providing MEP services. Other business verticals of the Company include substation and transmission lines, data centre solutions, operation & maintenance services, and hybrid energy division. SWPL’s diverse portfolio includes high voltage and low voltage electrical systems, HVAC systems, diesel generating sets (DG Sets), solar power generation, structured data cabling, integrated fire alarm system, security systems, etc. Acuité believes that SWPL will continue to derive benefits from its experienced management and established presence and track record of operations over the medium term. Average financial risk profile SWPL’s financial risk profile remains average marked by average debt protection metrics albeit moderate net worth and relatively low gearing. The net worth of the company stood at Rs. 862.71Cr. as on March 31, 2025, compared against Rs.909.97 Cr. as on March 31, 2024 The net worth primarily comprises compulsorily convertible non-cumulative preference shares amounting to Rs. 900 Cr. and a perpetual loan of Rs. 173.58 Cr. from the promoter group, which is considered quasi-equity as on March 31, 2025. Additionally, the company has significant exposure to its subsidiaries, with investments totalling Rs. 462.28 Cr. in FY25. The gearing (debt-to-equity) of the company stood at 0.99x as on March 31, 2025, as against 0.63x as on March 31, 2024. The company has a total debt of Rs. 851.87 Cr. as on March 31, 2025, as against Rs. 576.63 Cr. as on March 31, 2024. Furthermore, the debt protection matrices of the company improved with interest-coverage-ratio (ICR) and debt-service- coverage-ratio (DSCR) of 1.35 times and 1.25 times for FY25 as against 0.22 times and 0.03 times in FY24 respectively. Also, the Debt to EBITDA of the company stood high at 5.58x for FY25 as against 16.40x for FY24.  Acuite believes that financial risk profile of the company will remain average in near to medium term.

Weaknesses

­Subdued Operating performance with modest order book position The revenues of the company witnessed decline in the revenue that stood at Rs. 1586.76 Cr. in FY25 as against Rs. 1912.53 Cr. In FY24 due to the sale of data centre division and due to lower execution of projects. The company has booked revenue of Rs. 295.3 Cr. In Q1FY26. The company is curtailing its presence in higher ticket-size orders in data centres, MEP mega, industrial firefighting, and transmission and distribution (T&D). As of September 30, 2025, the company’s Order Book stands at Rs. 2,243 crores which gives revenue visibility for the medium term. The company incurred EBITDA losses of Rs.123.95 Cr. in FY25 as compared to profit of Rs. 0.63 Cr. FY24 impacted by elevated input material costs and the presence of lower-margin projects in the order book. The PAT stood at Rs. 26.37 Cr. in FY25 as against Rs. -146.86 Cr. in FY24. Also, the PAT margin stood at 1.66% in FY25 as against -7.68% in FY24. The reduction in FY2025 losses is driven by other income and exceptional items which majorly includes interest income on loans to subsidiary and write off from subsidiaries and profits from sale proceeds from DC division respectively. Acuite believes, the operating performance of the company would remain subdued due to expected pressure on profitability on the back of pending execution of legacy low margin orders. Working Capital intensive operations SWPL’S working capital operations continue to remain intensive marked by Gross Current Asset days (GCA) of 559 days for FY25 as against 572 days for FY24. This is primarily on account of significant other current assets, which include loans and advances extended to its subsidiaries amounting to Rs. 593.50 Cr. in FY25.The inventory days remained at similar level of 5 days for the last three years ended March 31, 2025. However, the receivables days stood at 225 days for FY25 as against 197 days for FY24. The creditor days stood at 314 days in FY25 as against 348 days in FY24. The working capital intensity is reflected in high average utilization of fund-based bank limits at 93.8 percent for the six months ended August 2025. Acuité believes that the working capital requirement is likely to remain at similar levels in the near to medium term.

Rating Sensitivities

­Substantial Improvement in revenues and profitability Changes in financial risk profile Deterioration in working capital cycle Timely receipt of proceeds from subsidiaries on account of divestment thereby supporting liquidity

Liquidity Position

Stretched

­SWPL’s liquidity position remains stretched, characterized by intensive working capital requirements, high gross current asset (GCA) days, and near-full utilization of fund-based limits. The company reported net cash accruals of Rs. 39.58 Cr. in FY25 against maturing debt obligations of Rs. 8.91 Cr. during the same period. However, going forward, net cash accruals are expected to be insufficient to fully cover repayment obligations. The current ratio stood at 1.23 times as on March 31, 2025, while cash and bank balances were Rs. 37.13 crore as on the same date. Additionally, receivables are anticipated from the sale proceeds of group companies, which may provide incremental liquidity support. Acuite believes that the liquidity of the company is likely to improve steadily over the medium term on account of expected improvement in cash accruals.

Outlook: Stable

Note on complexity levels of the rated instrument

­In order to inform the investors about complexity of instruments, Acuité has categorized such instruments in three levels: Simple, Complex and Highly Complex. Acuite’s categorisation of the instruments across the three categories is based on factors like variability of the returns to the investors, uncertainty in cash flow patterns, number of counterparties and general understanding of the instrument by the market. It has to be understood that complexity is different from credit risk and even an instrument categorized as 'Simple' can carry high levels of risk.
