Suzlon’s CRISIL Upgrade to AA-: The Credit Turnaround Behind the Rating Action

A company's credit profile is shaped by more than its revenue growth or order book. Its ability to convert business opportunities into operating cash flows, maintain liquidity and manage future investment requirements is equally important.

The latest rating action involving Suzlon Energy Limited provides a useful example.

In a rating rationale dated 27 October 2026, CRISIL Ratings upgraded Suzlon's long-term bank facility rating from CRISIL A+/Stable to CRISIL AA-/Stable. Its short-term rating was upgraded from CRISIL A1 to CRISIL A1+.

The company informed the National Stock Exchange and BSE about the upgrade on 28 October 2026. The rating action covers total bank loan facilities of ₹5,685 crore. CRISIL

An important distinction: ₹5,685 crore is the total amount of bank loan facilities rated, not necessarily the company's outstanding funded debt. The rating rationale's annexure includes letters of credit, bank guarantees, letters of comfort and proposed non-fund-based limits. CRISIL

The upgrade reflects a stronger business risk profile, supported by higher wind turbine deliveries and a healthy order book, alongside improvements in the company's financial risk profile and funding flexibility.

For other businesses, particularly those undertaking capital-intensive expansion, the case offers useful insights into how operational performance and financial discipline can work together to support a stronger credit profile.

1. Higher Wind Turbine Deliveries Strengthened Business Performance

One of the central factors behind the upgrade was the improvement in Suzlon's wind turbine generator (WTG) business.

According to CRISIL's assessment:

• Suzlon delivered approximately 2.5 GW of wind turbines in FY2026, compared with around 1.5 GW in FY2025.

• Its WTG business contributed approximately 67% of consolidated EBITDA in FY2026.

• Deliveries in Q1 FY2027 increased 14% year-on-year to 506 MW, compared with 444 MW in the corresponding quarter of the previous year.

• The WTG order book stood at approximately 6.4 GW as of August 2026, compared with around 5.5 GW as of May 2025.

This provides revenue visibility over the next two to three years, although actual performance will depend on execution and conversion of orders into deliveries. CRISIL

Why does this matter for credit assessment?

An order book can indicate future business opportunities, but it does not automatically translate into cash generation.

A company must have the manufacturing capacity, supply chain, project execution capability and working capital required to fulfil those orders.

For a business with significant fixed costs, higher delivery volumes can improve asset utilisation and operating leverage. However, delayed execution can have the opposite effect, leaving the company with fixed expenses but lower-than-expected revenue.

In Suzlon's case, CRISIL noted that the improvement in the WTG business supported stronger operating performance and the overall business risk profile.

2. Profitability Improved Alongside Delivery Growth

The increase in deliveries was accompanied by an improvement in operating profitability.

CRISIL reported that Suzlon's consolidated EBITDA margin increased to 17.2% in FY2026, compared with 16.7% in FY2025.

The WTG business showed a more pronounced improvement:

These figures indicate that the improvement was not limited to higher volumes. The WTG business also generated stronger operating profitability. CRISIL

CRISIL did, however, note that consolidated EBITDA margin moderated to 15.6% in Q1 FY2027 from 19.2% in Q1 FY2026. It attributed this to logistics disruption arising from the West Asia conflict and certain upfront expenses related to Suzlon 2.0 initiatives.

The agency expects margins to remain healthy on a full-year basis, with increased deliveries and scale benefits supporting absolute earnings. CRISIL

The broader lesson: Revenue growth and profitability need to be assessed together. Growth that does not translate into stronger operating earnings may not provide the same support to a company's financial position.

3. Recurring O&M Revenue Added Stability to Cash Flows

Another important element of Suzlon's business profile is its Operations and Maintenance (O&M) division.

Unlike equipment sales, which are linked to new orders and project execution, O&M services generate revenue through ongoing contractual relationships.

CRISIL highlighted the following performance:

• Approximately 15.7 GW of installed wind turbine capacity under O&M in India at the end of FY2026.

• O&M revenue of ₹2,073 crore in FY2026.

• O&M EBITDA of ₹839 crore, an increase of 8.8% over the previous year.

• Q1 FY2027 O&M EBITDA of ₹228 crore, compared with ₹188 crore in Q1 FY2026.

The division maintained an EBITDA margin of approximately 40% in FY2026. CRISIL expects it to continue generating EBITDA above ₹800 crore annually. CRISIL

Why recurring revenue matters

Businesses that depend entirely on new project orders may experience fluctuations in revenue and cash generation.

A stable service business can provide an additional source of operating cash flow during periods when new equipment deliveries or project execution are slower.

This does not eliminate business risk, but it can reduce dependence on a single revenue stream.

For companies in infrastructure, manufacturing, equipment and engineering services, recurring maintenance contracts, annual service agreements and long-term customer relationships can contribute to greater revenue visibility.

4. A Stronger Financial Risk Profile Supported the Upgrade

Operating improvements alone do not explain the rating action. CRISIL also highlighted Suzlon's financial position and improved funding flexibility.

As of 31 March 2026:

• The company maintained a net debt-free position.

• Consolidated debt stood at approximately ₹689 crore.

• Total outside liabilities to adjusted net worth (TOL/ANW) was 0.94 times, compared with 1.2 times as of March 2025.

• Interest coverage stood at approximately 6.2 times.

CRISIL also noted improved access to direct non-fund-based facilities, particularly from private sector banks. This strengthened the company's funding profile and supported lower overall finance costs. CRISIL

The liquidity position was also assessed as strong.

As of 30 June 2026, Suzlon had cash and cash equivalents of approximately ₹2,599 crore, including free cash of ₹1,392 crore. CRISIL expects healthy cash accruals of around ₹2,500 crore during the current fiscal year. CRISIL

These indicators are important because a company can report strong profitability while still facing liquidity pressure if its cash is tied up in inventory, receivables or ongoing projects.

A sustainable financial profile requires sufficient cash availability to meet interest payments, scheduled repayments and operating requirements.

5. Expansion Plans Will Continue to Be a Key Monitorable

Despite the upgrade, Suzlon's future performance will depend on its ability to manage expansion without weakening its financial position.

The company plans to increase annual capital expenditure to more than ₹600–700 crore, compared with historical annual capex of approximately ₹350–500 crore.

CRISIL expects this expenditure to be funded through internal accruals, allowing the company to maintain its net debt-free position. Any deviation from this expectation will remain a key rating monitorable. CRISIL

The rating rationale also discusses Suzlon's increasing focus on the DevCo model.

Under this approach, the company participates in project development activities, including land aggregation and securing project rights. This can support higher wind turbine deliveries and improve project execution.

However, it also introduces additional requirements relating to land acquisition, grid connectivity, project development and capital deployment.

CRISIL noted that approximately 25% of project capital is expected to be funded upfront, with the balance largely supported by customer receipts. It also noted management's stated intention to restrict capital deployment towards project development under this model to around ₹500 crore.

A material increase beyond the envisaged level could put pressure on capital intensity and liquidity. CRISIL

This is an important consideration for any business pursuing expansion through a project-led operating model.

Growth can strengthen a company's market position, but the funding structure and timing of cash flows must remain manageable.

6. What Risks Does CRISIL Continue to Monitor?

A rating upgrade does not mean that all business and financial risks have disappeared.

CRISIL identified several factors that continue to require attention.

Operating leverage

The WTG business has relatively high fixed costs. If deliveries or project execution slow down, fixed costs may not be adequately absorbed, potentially affecting operating margins and cash flows.

The increasing contribution of EPC activities also introduces additional execution and working capital requirements.

Suzlon's EPC contribution increased from approximately 22% of revenue in FY2025 to 32% in FY2026. Management is targeting approximately 50% by FY2030.

Competitive intensity

The wind energy sector remains competitive, with domestic and international players competing for orders and market share.

Sustaining deliveries and profitability will be important as the business expands.

Historical financial stress

CRISIL also considered Suzlon's financial history, including past defaults and restructuring.

The company's last restructuring was in June 2020, followed by refinancing in May 2022. The earlier 16-lender consortium was replaced by two lenders, and unsustainable debt was extinguished through conversion to equity.

The company has since improved its financial position and access to direct bank exposure. However, the historical experience remains relevant when assessing its financial flexibility. CRISIL

What could affect the rating going forward?

CRISIL's published rating sensitivity factors include:

• Sustained WTG delivery volumes above approximately 3.5–4 GW annually.

• Higher-than-expected EBITDA and improvement in the working capital cycle.

• A decline in order book or execution volumes that pushes operating margins below the 13–15% range.

• Higher-than-expected debt-funded acquisitions or capital expenditure.

• A sharp deterioration in liquidity.

These are the agency's stated rating sensitivity factors, not predictions of future rating actions. CRISIL

What Can Indian Businesses and CFOs Learn From Suzlon's Rating Upgrade?

Suzlon's experience provides several practical lessons for companies planning to raise debt, expand capacity or undergo a credit rating assessment.

1. Build a clear connection between the order book and cash flows

A large order book is useful only when the company can execute the orders profitably.

Finance teams should be able to explain the conversion schedule, expected margins, customer payment terms, procurement requirements and working capital needed for execution.

2. Develop revenue streams that provide greater visibility

Recurring revenue from maintenance, annual service contracts and long-term customer relationships can support cash flow stability.

Companies should identify how much of their revenue comes from recurring operations and how much depends on new orders or one-time projects.

3. Monitor leverage alongside capital expenditure

An expansion plan should include a realistic assessment of funding requirements.

Management should distinguish between capex funded through internal accruals, equity and additional borrowing. Any significant deviation from the original funding plan should be reflected in updated financial projections.

4. Maintain adequate liquidity buffers

Companies should monitor cash balances, undrawn facilities, working capital utilisation and upcoming repayment obligations.

A profitable business can still face financial stress if cash inflows are delayed or working capital requirements rise unexpectedly.

5. Address historical financial concerns with evidence

Past defaults, restructuring or weak financial performance may remain relevant to an assessment.

Management should be prepared to explain what has changed, how debt obligations have been managed and whether the improvements are sustainable.

Financial statements, repayment records, lender conduct and current cash-flow projections should support that explanation.

Implications for Banks and NBFCs Financing Capital-Intensive Businesses

The Suzlon case also offers relevant considerations for banks, NBFCs and other lenders financing manufacturing, renewable energy and infrastructure businesses.

A lending assessment should not rely exclusively on the size of a borrower's order book or projected revenue.

It should consider:

• The company's ability to convert orders into completed projects and cash receipts.

• The level of fixed costs and the impact of lower capacity utilisation.

• Working capital requirements during project execution.

• The stability of recurring service or maintenance income.

• Existing funded and non-funded banking exposure.

• The company's ability to fund planned capex without excessive leverage.

• Liquidity available to meet repayment obligations under less favourable operating conditions.

For lenders, the distinction between operating growth and sustainable debt-servicing capacity remains essential.

A company may be expanding rapidly, but its financing structure must allow it to manage delays, cost increases and changes in customer payment cycles.

The Bigger Takeaway: Sustainable Growth Matters More Than Growth Alone

Suzlon's upgrade to CRISIL AA-/Stable and A1+ reflects a combination of stronger wind turbine deliveries, a healthy order book, improved operating profitability, recurring O&M cash flows and a stronger financial risk profile.

At the same time, the rating rationale identifies execution, working capital, operating leverage and future capital expenditure as important areas to monitor.

For Indian businesses, the broader message is clear: a strong credit profile is built through the relationship between business performance, cash generation, liquidity and financial discipline.

Companies planning expansion or raising debt should ensure that their financial projections reflect realistic operating assumptions and funding requirements.
