Rating Rationale |
Acuité has upgraded its long-term rating to ‘ACUITE A-’ (read as ACUITE A minus) from ‘ACUITE BBB+’ (read as ACUITE triple B plus) on the Rs. 452.50 Cr. bank facilities and short-term rating to 'ACUITE A2+' (read as ACUITE A two plus) from 'ACUITE A2' (read as ACUITE A two) on the Rs.150.00 Cr. bank facilities of Apollo Micro Systems Limited (AMSL). The outlook remains 'Stable'.
Rationale for upgrade : Acuite, vide its press release dated 25th June, 2025, had upgraded its rating by one notch against which the client had appealed and provided further information and clarification particularly with respect to high inventory holding and its liquidity position. Further, Acuite continues to consider significant improvement in the company's scale of operations in FY2025. Over the past four years ending in FY2025, the company's earnings profile, including operating income, EBITDA, and PAT, has achieved a CAGR of 30 percent, driven by better execution of the order book. Additionally, the rating is supported by an equity infusion of Rs. 742.24 Cr. in FY2026 by both non-promoters and promoters on a preferential basis, for expansion of existing business and to manage increasing working capital requirements aligned with expected increase in scale of operations which will be enhancing the company's capital structure, liquidity, and financial risk profile. The operating margins have ranged between 22.99 and 22.57 percent over the last two years ending FY2025. The rating also considers the healthy order book position of Rs. 600.00 crore as of March 2025. It also factor's in the acquisition of IDL Explosives Ltd by it's subsidiary company which brings together over a century of specialized expertise in the niche and growing sector — 64 years in energetics and commercial explosives, and over 40 years in integrated weapons systems, AMSL will become fully integrated Tier-1 defence OEM. The acquisition not only enhances the manufacturing capabilities but also broadens the solutions portfolio across critical areas of India’s defence supply chain. Furthermore, the rating benefits from the promoters' extensive experience of over 30 years in the aerospace and defense industries.
However, the rating remains constrained by its intensive nature of working capital operations and susceptibility to risks inherent in tender-based business and long gestation period of projects. |

Key Rating Drivers |
Strengths |
AMSL has been an established player since 1985 in the electronic system design manufacturing (ESDM) segment with extensive experience of its promoter, Mr. B Karunakar Reddy in the aerospace and defence industries spanning over 40 years. AMSL has a strong R&D team focused on developing new products. The company works with the DRDO for research on strategic defence missions, developing commercially off the shelf solutions, which are the proprietary products of AMSL. It focuses on R&D as reflected by the increasing spend on the same over the years. Mr. C V S Prasad, one of the directors, has over 27 years' experience in defence electronic systems manufacturing, particularly critical systems and has worked with organizations like the Indian Space research Organization (ISRO) and Semi- Conductor Laboratory (SCL) in research department. The company provides electric and electronic hardware and software solutions for mission-critical applications to defence, aerospace, navy, and home land security among others. AMSL derives significant benefit from its promoter experience and has established strong relationships with its customers as well as suppliers for repeat business. The major customers include the Ministry of Defence (MoD), Defence Research and Development Organisation (DRDO), BrahMos Aerospace Private Limited, Bharat Electronics Limited (BEL), Hindustan Aeronautics Limited (HAL), and units operated by the Indian Space Research Organisation (ISRO) among others. Acuité believes that a similar growth trajectory is likely to continue over the medium term backed by experienced management and an established longstanding relationship with reputed clientele.
The company has reported a year-on-year (YOY) significant growth of 51.24 percent in FY2025 compared to the previous year, largely attributed to the execution of the order book. The revenue of the company stood at Rs. 562.07 Cr. in FY2025 as against Rs. 371.63 Cr. in FY2024. The operating margin stood at 22.73 percent in FY2025 as against 22.57 percent in FY2024. The company has an unexecuted order book position of Rs. 600.00 Cr. as of March 31st, 2025. Additionally, the capex of Rs. 149.05 Cr. in Electronic City is expected to be completed in the current year (Q2FY2026), which is expected to result in an increase in the scale of operations over the medium term. Acuité believes that the company will continue to sustain its order book position and maintain its business risk profile over the medium term.
The company’s financial risk profile is healthy with low gearing and moderate debt protection metrics. The net worth of the company stood at Rs.603.64 Cr. as of March 31, 2025 against Rs.517.56 Cr. as on March 31, 2024, and and Rs.383.70 Cr. as of March 31, 2023. The net worth improved due to the addition of premium on fresh issue of Rs. 131.50 Cr. in FY2024.The gearing of the company stood at 0.49 times as on March 31, 2025, against 0.40 times as on March 31, 2024. Debt protection metrics – Interest coverage ratio and debt service coverage ratio stood at 3.98 times and 2.52 times as on March 31, 2025, respectively as against 2.85 times and 2.33 times as on March 31, 2024, respectively. Tol/ TNW stood at 1.08 times as on March 31, 2025, as against 0.84 times as on March 31, 2024. The debt to EBITDA of the company stood at 2.23 times as on March 31, 2025, as against 2.40 times as on March 31, 2024. Acuité believes that the financial risk profile will remain healthy over the medium term on account of the company's healthy capital structure and stable operations.
AMSL operates in a niche segment of the high entry barrier Defence and Aerospace industry. The company is ‘Centre for Military Airworthiness and Certification (CEMILAC)’ certified, making it an approved design house for the design and development of software and equipment for military aircraft applications. This certification is based on technical experience and the past record of such authorized design houses. AMSL deals with reputed clientele like Bharat Dynamics Limited, Bharat Electronics Limited, and the Defence Research and Development Organisation (DRDO), among others. As of March 25, AMSL has an unexecuted order book position of Rs. 600.00 Cr. Acuité believes that the high entry barrier, coupled with the long-term nature of the contracts in the order book, provides revenue visibility over the medium term. Further, AMSL's growth prospects remain healthy, supported by the Indian Government’s focus on indigenization in the defense sector amid the Make in India thrust.

Weaknesses |
AMSL's working capital cycle remains significantly elongated, with Gross Current Asset (GCA) days of 628 days in FY2025 as against 740 days in FY2024, primarily driven by stretched receivables and elevated inventory levels. However, there is improvement in GCA days in FY2025 mainly on account of improved receivables in FY2025, which declined to 155 days, supported by the execution of commercial orders during the year. The high inventory as of March 31, 2025, is attributed to pre-emptive stocking of critical raw materials. Additionally, systems supplied by the company are subject to post-delivery testing by customers, and payments are released only upon successful completion, contributing to elevated debtor days—155 days in FY2025. To partially fund its working capital needs, the company stretches creditor payments, though these are secured through Letters of Credit (LCs). AMSL’s solutions are integrated within broader delivery systems assembled by other system integrators, with final deployment by the Ministry of Defence (MoD), further extending the operating cycle. Acuité notes that while operational improvements are expected over the medium term, the company’s ability to moderate its working capital intensity will remain a key sensitivity for its credit profile.
The business depends on success in bidding for tenders invited by defence public sector undertakings and research establishments. Establishments such as the Defence Research and Development Organisation (DRDO) invite tenders from qualified vendors for their R&D requirement and commence bulk production on successful completion of product development. Long-term revenue visibility is driven by the success of R&D projects and mass production. |

Liquidity Position: Adequate |
AMSL generated cash accruals of Rs.72.57 Cr. in FY2025, while its maturing debt obligations stood at Rs.8.08 Cr. during the same period. Going forward, the company is expected to generate adequate net cash accruals against maturing repayment obligations.

The Company has maintained unencumbered cash and bank balances Rs.0.20 Cr. and the current ratio stood at 1.73 times as on March 31, 2025.
