Cube Highways Trust’s ₹1,150 Crore NCD Raise: What It Says About Debt Refinancing and Credit Structure

For infrastructure businesses, raising debt is rarely just about securing capital.
The structure of that borrowing matters just as much.
Tenor, pricing, security, refinancing requirements, liquidity and the underlying cash-flow profile all form part of the credit conversation.
A recent transaction by Cube Highways Trust provides a useful example.
Cube Highways Trust, an Infrastructure Investment Trust focused on India's highways sector, has raised ₹1,150 crore through senior, secured, listed, rated and redeemable Non-Convertible Debentures (NCDs).
The NCDs carry a 7.50% per annum coupon, payable quarterly, and have a five-year tenor. The issue was undertaken through the NSE Electronic Bidding Platform.
The transaction forms part of a broader financing programme under which Cube InvIT has approval to raise financial assistance of up to ₹4,500 crore through one or more tranches and through a combination of NCDs, commercial papers and rupee-denominated facilities.
More importantly, the proceeds are intended to be used partly for refinancing outstanding senior debt facilities and/or commercial paper, as well as for capital expenditure and maintenance expenses related to the project's special purpose vehicles.
That makes the transaction relevant beyond the headline amount.
It provides a useful case study in how an infrastructure business can approach refinancing, funding structure and long-term debt.
What was raised?
Cube Highways Trust raised ₹1,150 crore through senior, secured NCDs with a five-year tenor and a fixed coupon of 7.50% per annum, payable quarterly.
The issuance attracted institutional participation from two major banks.
Axis Bank was allotted ₹550 crore, while ICICI Bank was allotted ₹600 crore.
The allocation included both anchor and non-anchor portions. Axis Bank received ₹165 crore as an anchor investor and ₹385 crore as a non-anchor investor. ICICI Bank received ₹180 crore as an anchor investor and ₹420 crore as a non-anchor investor.
The NCDs are secured and listed, adding another layer to the structure of the borrowing.
But the most important part for understanding the transaction is what the proceeds are intended to accomplish.
Refinancing is a key part of the transaction
A portion of the proceeds is proposed to be used to refinance outstanding senior debt facilities and/or commercial paper.
This is an important aspect of corporate debt management.
Refinancing allows a borrower to replace existing liabilities with new funding, potentially changing the maturity profile, funding mix or liquidity position.
For an infrastructure business with long-lived assets, the alignment between asset cash flows and debt maturities can be particularly important.
The objective is not simply to borrow more.
It is to ensure that the financing structure remains appropriate for the business and the cash flows generated by the underlying assets.
Why does the five-year tenor matter?
Infrastructure assets generally have long operating lives.
The debt used to finance them therefore needs to be considered in the context of the expected cash flows from those assets.
A five-year NCD provides a defined period before the principal becomes due.
For management, this creates several questions:

• What debt will mature during that period?
  
  

• What operating cash flows are expected?
  
  

• What additional capital expenditure may be required?
  
  

• How much refinancing will be needed at maturity?
  
  

• How will interest obligations interact with available cash flows?
  
  

The answer to these questions forms part of the broader assessment of financial risk.
A longer tenor does not automatically mean lower risk. What matters is whether the repayment structure is consistent with the borrower's financial capacity.
What does the AAA rating tell us?
Cube Highways Trust currently carries CRISIL AAA with a Stable outlook on its long-term rated instruments. CRISIL's current company factsheet lists its ₹1,000 crore NCDs and other long-term facilities under the AAA rating category, with the Stable outlook dated September 18, 2026.
A AAA rating represents the rating agency's assessment of the credit quality of the rated obligation under its methodology and available information.
It is important, however, to distinguish between a credit rating and an investment recommendation.
A rating is an independent credit opinion. It does not constitute a guarantee of repayment, investment return or future performance.
For businesses considering debt raising, the larger lesson is that the rating sits within a broader credit assessment.
Investors and lenders may consider factors such as cash-flow visibility, leverage, liquidity, asset quality, debt structure and the business environment.
The underlying cash flows remain important
Cube Highways Trust operates highway assets under the Infrastructure Investment Trust structure.
The ability of such a platform to service debt is linked to the cash flows generated by its underlying portfolio as well as its financial structure and liquidity.
Cube Highways Trust reported FY26 consolidated revenue from operations of ₹4,239 crore and consolidated EBITDA of ₹3,092 crore. Its FY26 annual report also highlighted traffic growth and a net debt-to-enterprise value ratio of 46.82%. The Trust stated that it maintained AAA/Stable ratings from CRISIL, India Ratings and ICRA.
These figures provide context for the broader financing story.
Debt capacity cannot be assessed by looking at the amount being raised alone.
The underlying earnings, cash generation, leverage and liquidity position are equally important.
What should businesses learn from the transaction?
The Cube Highways Trust transaction offers several useful lessons for businesses planning to raise or refinance debt.
1. Start before the maturity date
A major debt maturity should not become a last-minute financing exercise.
Management should maintain a forward-looking maturity schedule and identify potential refinancing requirements well in advance.
This provides more time to assess funding alternatives and prepare the business for lender or investor discussions.
2. Match debt with cash flows
The tenure and repayment structure should be evaluated against the company's expected cash flows.
A business with long-term contracted or relatively predictable cash flows may have different financing requirements from a company with highly seasonal or volatile earnings.
3. Understand the full funding structure
Debt should not be viewed in isolation.
Businesses need to consider existing bank facilities, NCDs, commercial paper, working-capital facilities and other financial obligations together.
A new borrowing programme can affect the overall maturity profile and liquidity position.
4. Security is part of the structure
Secured borrowing can provide lenders or investors with defined security over specified assets or receivables.
However, security is only one part of the credit assessment.
The borrower's overall financial capacity and ability to service the obligation remain important.
5. Ratings reflect the broader credit profile
A credit rating is not determined by one financial metric.
The assessment can involve business risk, financial performance, leverage, liquidity, cash-flow strength, industry conditions and other relevant factors.
That is why businesses preparing for a rating exercise need to understand their complete credit profile rather than focusing on a single number.
Debt refinancing is also a credit-planning exercise
The ₹1,150 crore Cube Highways Trust transaction demonstrates how refinancing can be integrated with the broader funding requirements of an infrastructure platform.
Part of the new funding is intended to refinance existing debt and commercial paper, while the financing programme also provides for capital expenditure and maintenance requirements.
This highlights a broader principle:
The quality of a borrowing decision depends not only on the amount raised, but on how the new liability fits into the company's overall financial structure.
For CFOs and promoters, that means looking ahead.
What debt is due?
What funding will be required for growth?
How much liquidity is available?
How will interest costs affect cash flows?
And what will the company's credit profile look like when it approaches lenders or investors?
These questions should be addressed before the financing requirement becomes urgent.
What businesses should review before approaching lenders or investors
A practical pre-debt review should cover:
Debt maturity profile
Map existing borrowings and identify significant repayment dates.
Leverage
Assess debt relative to the company's earnings, net worth and asset base.
Liquidity
Understand available cash, undrawn facilities and near-term obligations.
Cash-flow visibility
Assess whether operating cash flows can support interest and principal obligations.
Funding mix
Review the balance between bank debt, NCDs, commercial paper and other forms of financing.
Refinancing requirements
Identify liabilities that may need to be refinanced and assess them well before maturity.
Business and sector risks
Consider demand, regulation, competition, input costs and other factors that could affect future cash generation.
The FinMen perspective
Debt raising should be approached as a credit exercise, not simply a funding exercise.
A company preparing for a new borrowing programme needs to understand how its business model, financial performance, leverage, liquidity and future funding requirements come together to form its credit profile.
