IndiGrid Infrastructure Trust approved the allotment of two series of non-convertible debt securities (NCDs) on August 20, 2026, raising a total face value of ₹1,100 crore. The investment manager, IndiGrid Investment Managers Limited, sanctioned the allotment pursuant to Regulation 51 of SEBI’s Listing Obligations and Disclosure Requirements Regulations, 2015, and Regulation 23 of the SEBI Infrastructure Investment Trusts Regulations, 2014.
The issuance consists of two distinct tranches with varying tenures but identical credit ratings and coupon structures. Series AI represents a shorter-term liability of ₹350 crore maturing in five years, while Series AJ constitutes a longer-term obligation of ₹750 crore with a tenor of 10 years. Both series were issued on a private placement basis as partly paid-up, senior, secured, listed, and redeemable debentures.
Instrument Details
The debt securities carry a uniform coupon rate of 7.44% per annum, payable quarterly. Both series have received the highest credit rating from major agencies, reflecting the trust’s strong credit profile.
| Metric: | Series AI | Series AJ |
|---|---|---|
| Face Value: | ₹350 crore | ₹750 crore |
| Tenure: | 5 years | 10 years |
| Maturity Date: | August 20, 2031 | August 20, 2036 |
| Coupon Rate: | 7.44% p.a. | 7.44% p.a. |
| Credit Rating: | AAA/Stable | AAA/Stable |
| Rating Agencies: | Crisil, ICRA | Crisil, ICRA |
Each security has a face value of ₹1,00,000. For Series AI, 35,000 units were allotted with a paid-up value of ₹20,000 per unit, aggregating to ₹70 crore in immediate capital infusion against the ₹350 crore face value. Similarly, for Series AJ, 75,000 units were allotted with the same paid-up structure, resulting in ₹150 crore in paid-up capital against the ₹750 crore face value.
What the Numbers Show
The split between the two series indicates a strategic approach to liability management, balancing near-term funding needs with long-term capital stability. The equal coupon rate across different tenures suggests a flat yield curve expectation or standardized pricing strategy for this issuance window. The substantial size of the Series AJ tranche (₹750 crore) relative to Series AI (₹350 crore) implies a greater reliance on long-term secured debt to fund infrastructure projects, aligning with the typical asset-liability matching requirements of an infrastructure trust.
The securities are proposed to be listed on the Bombay Stock Exchange (BSE). Axis Trustee Services Limited and IDBI Trusteeship Services Limited serve as trustees for the issue. The allotment was certified by Urmil Shah, Company Secretary and Compliance Officer of IndiGrid Investment Managers Limited.
