Rating Rationale

Acuité has upgrade its long-term rating to 'ACUITE A-' (read as ACUITE A minus) from 'ACUITE BBB+' (read as ACUITE triple B plus) and its short-term rating to 'ACUITE A2+' (read as ACUITE A two plus) from 'ACUITE A2' (read as ACUITE A two) on the Rs. 210.00 crore bank facilities of Kilburn Engineering Limited (KEL). The outlook has been revised from ‘Positive’ to 'Stable'.

Rationale for upgraded and revision in outlook
Acuite, vide its press release dated 04th November 2025, had reaffirmed its rating and revised its outlook from ‘Stable’ to ‘Positive’ against which the client had appealed and provided further information with respect to H1FY2026 financials. Accordingly, Acuite takes note of group's continued improvement in the operating performance as reflected in the Q2FY2026 financials. Further, the rating upgrade continues to derive comfort from the group's longstanding relationship with reputed clients. The ratings favourably factors in Kilburn Group’s (KGs) healthy order book position providing strong medium-term revenue visibility buoyed by its execution capabilities. The rating also factors in long track record of operations and expertise of the group in the manufacturing of customised systems and equipment’s for diverse applications. The rating is further supported by the healthy financial risk profile characterized by healthy net worth, below unity gearing and comfortable debt protection metrics. These strengths are however, partly offset by the working capital-intensive nature of operations, cyclicality in the end user industry and their capex plans and business cycles.

Further, the rating reflects the expected synergetic benefits at financial and business level from Kilburn Engineering Limited's (KEL) 100 per cent acquisition of M E Energy Private Limited (MEEPL) in February 2024, as well as the further 100 per cent acquisition of Monga Strayfield Private Limited (MSPL) in January 2025. However, the stabilization of operations and the realization of these benefits on the group’s operational and financial risk profile remain to be seen, thereby it will remain a key rating monitorable.

Analytical Approach

Extent of Consolidation
•Full Consolidation
Rationale for Consolidation or Parent / Group / Govt. Support
­Acuite has consolidated the business and financial risk profiles of Kilburn Engineering Limited (KEL), M E Energy Private Limited (MEEPL) and Monga Strayfield Private Limited (MSPL) together referred to as the ‘Kilburn Group’(KG). The consolidation is on the basis of MEEPL and MSPL being the wholly owned subsidiaries of KEL, corporate guarantee given to the MEEPL on its bank facilities by KEL and operational and financial synergies within the group. Further the consolidation also includes the step-down subsidiaries of KEL.
Key Rating Drivers

Strengths

­Long operational track record and strong customer base
KEL has a long track record of more than three decades in the industry and has built healthy relationships with its customers and suppliers, ranging from 5 to 30 years. The strong relationships with customers, who have a very strong credit profile, ensure regular orders and low counterparty credit risk. Further, in February 2024, KEL acquired 100 per cent of the equity share capital of MEEPL. This acquisition is expected to augment the organizational prowess, as MEEPL specializes in the production of thermal engineering and heat recovery systems, which are expected to complement Kilburn Engineering’s existing drying systems. Furthermore, on January 28, 2025, KEL acquired 100% of the equity share capital of Monga Strayfield Private Limited, which is engaged in radio frequency drying and heating technologies and specializes in sheet metal fabrication. This acquisition is expected to further strengthen Kilburn’s market position and expand its offerings in key industrial sectors. The synergy of both acquisitions is expected to help tap into the existing client bases of all three entities, while also providing a bundled solution.


Revenue growth and improvement in the profitability
The group’s operating income stood at Rs. 424.46 crore in FY2025 as against Rs. 329.48 crore in FY2024. The group’s EBITDA margin improved marginally to 24 per cent in FY2025 as against 23.37 per cent in FY 2024. Further, in H1FY2026, the group reported operating income of Rs. 288.99 crore and EBITDA of Rs. 79.23 crore as against Rs. 190.40 crore and Rs. 42.72 crore in H1FY2025. Further, the PAT margin stood at 14. 70 per cent in FY2025 as against 15.34 per cent in FY2024. The improvement in the overall performance of the group is primarily on account of acquisition of MEEPL (acquired in February 2024) and Monga Strayfield Private Limited (acquired in January 2025). The group has an unexecuted order book position of around Rs. 492.03 crore as of September 2025, of which Rs. 340.72 crore pertains to KEL. The group’s order book position remains moderate, providing revenue visibility for the near to medium term. Acuité believes that the revenue of the group is expected to improve further due to the healthy order book position and its execution on the back of expansion plans.

Healthy financial risk profile
The group’s financial risk is healthy, with a healthy net worth, below-unity gearing, and comfortable debt protection metrics. The tangible net worth increased to Rs. 351.14 crore as of March 31, 2025, reflecting sustained profitability and an increase from Rs. 175.93 Cr. as of March 31, 2024 due to accretion of profits to reserves and conversion of equity share warrants to equity share capital. The group's gearing is comfortable at 0.25 times as of March 31, 2025 as against 0.48 times as of March 31, 2024. The comfortable coverage debt protection metrics are reflected by the Interest Coverage Ratio (ICR), which stood at 7.05 times and the Debt Service Coverage Ratio (DSCR), which stood at 4.29 times as of March 31, 2025 as against 8.14 times and 6.48 times as of March 31, 2024 respectively. Total outside Liabilities/Total Net Worth (TOL/TNW) improved to 0.74 times as on 31st March 2025 as against 1.27 times as on 31st March 2024 while the Debt/EBITDA improved to 0.84 times as on 31st March 2025 as against at 1.06 times as on 31st March 2024. KG is undertaking a brownfield expansion at Saravali involving a capital outlay of ~Rs. 30 crore and a Phase 2 expansion at subsidiary MEEPL with an indicative capex requirement of Rs. 7-12 crore funded by internal accruals to meet growing captive demand from increasing order inflows. Acuite believes, the financial risk profile of the group will continue to remain healthy over the medium term due to steady cash accruals.


Weaknesses

­Working capital intensive nature of operations
The working capital-intensive nature of the group’s operations is marked by high and increased Gross Current Assets (GCA) to 361 days as of March 31, 2025 as against 326 days as on March 31, 2024, primarily due to unbilled revenue of Rs. 199.09 crore as of March 31, 2025. The inventory days stood at 54 days, and debtor’s collection period stood at 91 days in FY2025 as against 45 days and 87 days in FY2024 respectively. Due to the time taken to execute the orders, the operating cycle takes between 2 to 6 months, resulting in a large working capital requirement and staggered deliverables. Acuité believes that the working capital operations of the group will remain intensive due to the nature of business.

Susceptibility of profitability to volatility in raw material prices and cyclicality in end user industry
The group’s major raw material is steel, making its profit margins susceptible to fluctuations in raw material prices. However, since steel purchases are spread over a period of time, the impact of price volatility is mitigated to some extent through averaging. Further, demand for the group’s products is driven by the capital expenditure plans of end-user industries, which are inherently cyclical.

Rating Sensitivities
  • Sustainable improvement in revenue while improving profitability
  • Elongation of the working capital cycle
  • Deterioration in financial risk profile on the back of higher-than expected debt funded capex
  • Stabilization of operations and realization of benefits from the recent acquisitions on the group’s operational and financial risk profile.
 
Liquidity Position
Adequate

The liquidity position remains adequate, evidenced by moderate net cash accruals against no maturing debt obligations. The group’s has generated healthy net cash accruals of Rs. 69.72 crore in FY2025 against Rs. 4.86 crore repayment obligations during the same period. The free cash and bank balances stood minimal at Rs. 5.69 crore on March 31, 2025. The current ratio of the group improved to 2.14 times as on March 31, 2025 as against 1.72 times as on March 31, 2024. Further, the group has buffer in the fund-based limits with an average utilisation of ~44% for 6 months ending 31st August 2025 while the average utilisation for non fund based limits for 6 months ending 31st August 2025 is ~62%.
