India Ratings and Research (Ind-Ra) has assigned an 'IND A-'/Stable rating to STL Networks Limited (STLN) proposed non-convertible debentures (NCDs) worth INR 3,000.00 million. The agency has also affirmed the 'IND A-'/Stable/IND A2+' rating for the company's bank loan facilities of INR 25,000.00 million.
Key Rating Drivers
The ratings reflect STLN's robust business profile, supported by its established track record in the telecom industry and end-to-end capabilities in executing complex and mission-critical projects. Ind-Ra expects healthy revenue growth for STLN over 2HFY26-FY27, backed by a strong order book of over INR 65,000.00 million as of end-June 2025, representing a book-to-bill ratio of over 5.5x based on FY25 revenue.
Financial Performance and Outlook
STLN's consolidated revenue declined by about 20% year-on-year to INR 11,800.00 million in FY25, primarily due to the company's selective approach in order acquisition. The EBITDA margin moderated slightly to 6.3% in FY25 from 6.7% in FY24.
| Financial Metrics (Consolidated) | FY25 | FY24 (Restated) |
|---|---|---|
| Revenue (INR million) | 11,800.00 | 14,700.00 |
| EBITDA (INR million) | 700.00 | 1,000.00 |
| EBITDA margin (%) | 6.30 | 6.70 |
| Interest coverage (x) | 1.00 | 1.40 |
| Net leverage (x) | 9.70 | 4.70 |
Despite the current modest credit metrics, Ind-Ra anticipates gradual improvement in net leverage and interest coverage over the near to medium term. This expectation is driven by projected enhancements in profitability, moderation of the working capital cycle, and the potential release of locked-up funds.
Order Book and Industry Outlook
STLN secured a significant contract worth about INR 22,000.00 million under Bharat Net Phase III during Q1FY26, boosting its outstanding order book to over INR 65,000.00 million as of June 2025. The company is well-positioned to capitalize on India's accelerating digital transformation, with key government initiatives such as BharatNet Phase III, Smart Cities Mission, and Digital India driving large-scale connectivity and infrastructure development.
Challenges and Constraints
The rating is partially constrained by STLN's modest credit metrics, elongated working capital cycle, and significant working capital lock-up in a few projects. The company faces challenges with delays and disputes in some projects, resulting in working capital being tied up. However, management expects a significant portion of the locked-up amount to be cleared by 1HFY27.
Liquidity and Debt Profile
STLN's liquidity position is supported by adequate free cash and equivalents, undrawn working capital limits, and expected positive cash flow from operations over 2HFY26-FY27. The company had a consolidated free cash and equivalent of INR 792.00 million at end-September 2025. STLN has a term debt principal repayment obligation of INR 360.00-370.00 million each in FY26 and FY27, which Ind-Ra expects will be serviced through internal accruals and existing liquidity.
Conclusion
While STLN faces challenges in its working capital cycle and credit metrics, the company's strong order book, strategic position in the growing digital infrastructure sector, and expected improvements in financial performance provide a stable outlook. The successful execution of orders, improvement in profitability, and effective management of working capital will be crucial for maintaining and potentially improving the company's credit rating in the future.
