Detailed Rationale

Crisil Ratings has continued its rating on the long-term bank facilities, non-convertible debentures and commercial paper programme of Sterlite Technologies Ltd (STL) on ‘Rating Watch with Developing Implications’.
 

The continuation of rating watch factors in the proposed demerger of the company’s global services business into STL Networks Ltd (resulting company). Crisil Ratings notes that the NCLT approval for the demerger has been received. A portion of the rated facilities may move to the demerged entity. Crisil Ratings believes that credit risk profile of STL is likely to benefit from the demerger because the services business has lower operating margin and higher working capital requirements relative to the products business staying under STL. On the other hand, the credit profile of the resulting company could be relatively weaker vis-à-vis STL. Thus, Crisil Ratings will continue to closely monitor the transaction and resolve the rating watch once there is clarity on the resulting business and financial risk profiles of both entities and on the movement of the rated facilities.

 

For the third quarter of fiscal 2025, STL reported a sequential decline in operating performance with revenues of Rs 1,261 crore and operating EBITDA of Rs 128 crore (EBITDA margin of 10.3%) compared to Rs 1,414 crore and Rs 145 crore respectively in the previous quarter. This was due to seasonality impact in exports market and slower than expected execution in certain orders in the services business due to clearance issues.

 

Crisil Ratings expects a recovery in the fourth quarter of fiscal 2025 with revival in demand in the US market with inventory destocking at the telcos. Furthermore, execution of large key orders like Bharatnet phase 3 and US BEAD programmed are expected to start accruing revenue from fiscal 2026 onwards. This should lead to improved capacity utilisation especially in the US market where realisations are higher. Sequential improvement in operating performance in line with Crisil Ratings expectations going forward will remain a key monitorable for the ratings.

 

Further, STL has implemented cost optimisation measures in the recent quarters resulting in cost savings despite operating at moderate capacity utilisations due to weak demand. Operating margins are expected to improve further from Q4FY25 onwards on account of expected improvement in capacity utilisation and STL’s efforts on wastage reduction in manufacturing process.

 

The company had raised equity of ~Rs 1,000 crore in April 2024 with the proceeds utilised towards deleveraging resulting in the improvement in the financial risk profile. However, net leverage is likely to remain elevated at ~3.5 times while interest cover is likely to remain modest for fiscal 2025 due to subdued profitability. Debt protection metrics are expected to improve in line with the improvement in operating performance. Further, the demerger of the GSB business shall benefit the financial risk profile of the remaining entity. However, any support to the demerged entity impacting the credit profile will also remain a key monitorable.

 

Additionally, Crisil Rating notes the $ 96.5 million jury verdict to Prysmian in a lawsuit against STL’s US subsidiary. The allegations include violation of non-compete agreements and unfair use of trade secrets to further the North America business. The matter is sub judice with STL pursuing legal remedies including filing for a petition challenging the verdict which will take time to settle. Currently, there is no impact on the US operations or legal liability. Any adverse impact on the business and/or financial risk profile including any liabilities arising due to this matter will remain key monitorable.

 

The ratings continue to reflect the dominant market position of STL in the optical fibre business, its strong order book providing healthy revenue visibility. These strengths are partially offset by subdued debt protection metrics, large working capital requirement and exposure to intense competition.

Analytical Approach

Crisil Ratings has combined the business and financial risk profiles of STL and its subsidiaries and joint ventures. STL has significant management control over these entities, which are in the same business and are strategically important to the company.

Key Rating Drivers & Detailed Description

Strengths:

• Leading position in Indian optical fibre market and global markets: STL has strong reputation in the optical fibre (OF) and optical fibre cable (OFC) segments in India and abroad, driven by its technically superior products. Its global ex-China OFC market share stood at 8% for third quarter of fiscal 2025 in line with fiscal 2024. The company is preferred by OFC manufacturers (for OF) and telecom operators and telecom infrastructure providers (for OFC). Furthermore, it is a one-stop shop for most clients because of its wide system integration and software services offerings. High-quality products, extensive clientele and diversified presence across the broadband infrastructure value chain should help the company sustain a strong foothold in the telecom cable industry over the medium term.

 

• Healthy capabilities and growth prospects with sizeable order book: STL is among the lowest-cost producers of OF and OFC because of extensive backward integration. Manufacturing OFs from the preform stage offers advantages in terms of cost and quality. The company has plants for power, nitrogen and electrolysis to meet its hydrogen and oxygen requirements. Moreover, it has facilities to produce silicon tetrachloride, the basic raw material for quartz glass manufacturing. With increase in penetration of broadband services, ongoing rollout of 5G services, massive investments towards data centres, focus of the government on rural digitisation, approval of phase 3 of BharatNet project and implementation of Smart City projects and the BEAD programme in North America, the medium-term demand outlook is healthy.

 

• Orders of Rs 9050 crore as on December 31, 2024 provide revenue visibility over the medium term. Of the total orders, ~53% are from the optical networking and digital and technology businesses. This indicates healthy business prospects for STL despite the demerger of its global services business.

 

Weaknesses:

• Subdued debt protection metrics and large working capital requirement: Given the slump in operating performance, debt protection metrics are expected to remain subdued for fiscal 2025. This is despite reduction in net debt to Rs 2,021 crores as on June 30, 2024 post equity-raise of Rs 1000 crore completed in April 2024. Net leverage (net debt to Ebitda ratio) was elevated at around 4.4 times for fiscal 2024 compared to 3.2 times in fiscal 2023 while interest cover deteriorated to 1.7 times for fiscal 2024 compared to 3.2 times in fiscal 2023. Furthermore, interest coverage ratio is likely to remain subdued and net leverage is expected at 3-3.5 times for fiscal 2025. Turnaround in operating performance leading to sustained improvement in financial risk profile going forward will be a key monitorable. Working capital requirement remains elevated due to the high proportion of services business. This leads to stretched receivables since the counterparties are majorly Indian public sector undertakings (PSUs). This is reflected in gross current assets of ~300 days as on March 31, 2024. The working capital cycle will improve significantly once the global services business is carved out from STL.

 

• Exposure to intense competition and capex by telcos: The company derives a large part of its revenue from overseas markets and faces intense competition in the international OF and OFC markets. In the domestic market as well, these segments are susceptible to the capex cycles of telecom service providers. Globally, most contracts are finalised through an intensely competitive bidding process, which limits the pricing power of players. However, STL has the largest capacity and is a leading player in the domestic market despite competitive pressure from peers such as Himachal Futuristic Communications Ltd, Vindhya Telelinks Ltd, and Finolex Cables Ltd.

 

Based on recommendations from the Directorate General of Trade Remedies (DGTR), the Ministry of Finance imposed definitive anti-dumping duty in August 2023 for a period of five years on specific optical fibre imports from China, South Korea and Indonesia. Import data suggests that this move has mitigated the negative impact of low-priced and low-quality imports on domestic players and will continue to benefit them. Similarly, the UK and European Union (EU) have imposed anti-dumping duty on specific OF imports from China, which is benefitting the domestic players that export to the UK and the EU.

Liquidity: Strong

Liquidity will be strong, supported by expected net cash accrual of Rs 300-500 crore per annum over the medium term, cash balance of ~Rs 481 crore as on September 30, 2024, and healthy cushion in bank lines. Against this, the company has term debt obligation of around Rs 270 crore in fiscal 2026 which can be met via internal accrual and refinancing. Capex of Rs 100-150 crore for fiscals 2025 and 2026 will be funded largely through internal accrual.

 

Environment, social and governance (ESG) profile

Crisil Ratings believes the ESG profile of STL supports its already strong credit risk profile.

 

The telecom equipment sector is exposed to material impact on the environment as waste associated with end-of-life network equipment and hardware can pollute land resources. Optical fibres are vital for ensuring uninterrupted telecom services to society and the economy. STL is continuously focused on mitigating its environmental and social impact.

 

Key ESG highlights:

• The company is committed to achieve net zero emissions by 2030. Also, by 2030, STL aims to become water-positive across all its manufacturing locations globally. To achieve this target, STL implemented water-recycling models. All its manufacturing plants in Aurangabad are zero liquid discharge certified. Around 1.45 lakh cubic metre of water recycled in the manufacturing process and over 7,500 tonne of carbon dioxide emissions avoided through energy efficiency measures.
• All plants are zero waste to landfill certified.
• The company has started using co-processing in partnership with cement companies as one of the disposal and management solutions, which helps convert waste to energy.
• Female employees constitute 16.7% of the workforce, which is higher than all its peers.
• Its governance structure is characterised by 57% of the board comprising independent directors, split in chairman and CEO positions, healthy investor grievance redressal and extensive disclosures.

 

There is growing importance of ESG among investors and lenders. STL’s commitment to ESG principles will play a key role in enhancing stakeholder confidence, given its moderate share of market borrowings in overall debt and access to both domestic and foreign capital markets.

Rating sensitivity factors

Upward factors:

• Significant improvement in operating performance driven by recovery in volumes or realisations, translating into healthy operating margins sustaining above 15-17%.
• Recovery in operating profitability leading to improvement in return on capital employed
• Considerable increase in cash accrual or other deleveraging measures resulting in material improvement in debt protection metrics

 

Downward factors:

• Lower than expected turnaround in scale of operations resulting in operating margins sustaining below 10%
• Continued pressure on operating profitability leading to weak debt protection metrics on a sustained basis
• Adverse impact of ongoing litigations or contingent liabilities on the financial risk profile
