Cube Highways Files ₹5,000 Cr OFS for India's First Public InvIT Conversion

Introduction

Cube Highways Trust, a major player in India's road infrastructure sector, has filed preliminary papers with the Securities and Exchange Board of India (SEBI) for an Offer for Sale (OFS) of units aggregating up to ₹5,000 crore. This move is part of its plan to convert from a privately listed Infrastructure Investment Trust (InvIT) to a publicly listed one, marking the first such transition in the country. The conversion aims to enhance liquidity and provide access to a wider pool of investors, setting a precedent for infrastructure financing in India.

The Landmark Filing Explained

The proposed offering is entirely an OFS, meaning existing unitholders will sell their units to new investors, and the trust itself will not receive any proceeds from the issue. This strategic transaction is designed to facilitate the shift from a private placement structure to a public trading platform. The filing with SEBI is the first formal step in this process, which, if successful, will allow Cube Highways Trust to be traded on Indian stock exchanges, offering retail and institutional investors a chance to participate in its growth story.

Who are the Selling Unitholders?

The OFS involves several existing investors offloading their holdings. The primary sellers include entities from the Cube Highways group, such as Cube Highways and Infrastructure II and Cube Highways and Infrastructure III. Other significant unitholders participating in the sale are Cube Mobility Investments, BCI IRR India Holdings, and Seventy Second Investment Company LLC. This diverse group of sellers underscores the planned shift in the trust's ownership structure as it moves into the public domain.

Strategic Rationale for Going Public

The primary driver behind this conversion is the pursuit of a broader and more diversified investor base. As a publicly listed entity, Cube Highways Trust will be able to attract capital from a wider spectrum of market participants, including select mutual funds, insurance companies, and pension funds. Historically, these institutional investors have had limited participation in privately listed InvITs due to liquidity constraints. A public listing is expected to resolve this issue, unlocking new pools of capital for future growth and acquisitions.

A Deep Dive into Cube Highways' Portfolio

As of September 2025, Cube Highways Trust operated a robust portfolio of 27 road assets spread across 12 states and one union territory. The portfolio is diversified by asset type, comprising 18 toll roads, 6 hybrid annuity models (HAM), and 3 annuity assets. These include a mix of Build, Operate, Transfer (BOT), Design, Build, Finance, Operate and Transfer (DBFOT), and Toll, Operation, Maintenance and Transfer (TOT) projects. The trust plans to acquire four additional highway and tunnel projects before the offer's completion, which will expand its portfolio to 31 assets and a total length of 9,811 lane kilometers.

Financial Health and Performance

Cube Highways Trust has demonstrated strong financial performance, supported by its extensive asset base. The trust's Assets Under Management (AUM) stood at ₹36,520 crore as of September 2025. For the fiscal year ending March 2025, it reported revenues of ₹3,307 crore, a notable increase from ₹2,916 crore in the previous year. This growth reflects stable toll collections and efficient operations across its network. The trust also reported strong quarterly results, with net sales of ₹944.28 crore for the quarter ending June 2025.

Key Financial Metrics

Backed by Global Investment Giants

The trust is backed by a consortium of prominent global investors, lending it significant financial credibility and strategic expertise. Its sponsors include I Squared Capital, a wholly-owned subsidiary of the Abu Dhabi Investment Authority (ADIA), British Columbia Investment Management Corporation (BCI), Abu Dhabi's sovereign investor Mubadala Investment Company, and Japan Highways International BV. This strong institutional backing has been instrumental in its growth and expansion.

Regulatory Tailwinds Favoring Conversion

Cube Highways' move comes at an opportune time, as India's market regulator, SEBI, has been actively working to ease the conversion rules for private InvITs to go public. Proposed reforms include reducing the mandatory capital contribution from sponsors and shortening lock-in periods for their holdings. These regulatory changes are designed to create a more favorable environment for infrastructure trusts to access public markets, which could unlock substantial capital for India's infrastructure development goals.

Market Impact and Future Outlook

This OFS is a significant event for the Indian capital markets, as it establishes a new pathway for privately held infrastructure assets to be monetized and managed through public vehicles. The successful listing of Cube Highways Trust could encourage other private InvITs to follow suit, deepening the market for infrastructure investments. The offer is being managed by a syndicate of leading financial institutions, including Kotak Mahindra Capital Company, HDFC Bank, HSBC Securities and Capital Markets (India), and JM Financial, with Axis Trustee Services acting as the trustee.

Conclusion

By filing for a ₹5,000 crore OFS, Cube Highways Trust is not just aiming to raise capital but is also pioneering a new chapter for InvITs in India. The transition to a public platform will test investor appetite for yield-oriented infrastructure assets and could significantly influence how large-scale infrastructure projects are funded in the future. The outcome of this offering will be closely watched by investors and industry stakeholders alike as a barometer for the evolving infrastructure investment landscape in the country.
