Cube Highways Files ₹5,000 Cr OFS for Public InvIT Debut

Introduction

Cube Highways Trust, a major infrastructure investment trust (InvIT), has filed preliminary documents with the Securities and Exchange Board of India (SEBI) for an Offer for Sale (OFS) of units worth up to ₹5,000 crore. This move is aimed at converting the trust from its current privately listed status to a publicly listed InvIT, a first for the Indian market. The transition is expected to enhance liquidity and provide access to a wider pool of capital, marking a significant development in India's infrastructure financing landscape.

Details of the Offer

The proposed issue is entirely an OFS, meaning existing unitholders will sell their stakes to new investors, and the trust itself will not receive any proceeds from the offer. The selling unitholders include BCI IRR India Holdings, Cube Highways and Infrastructure II, Cube Highways and Infrastructure III, Cube Mobility Investments, and Seventy Second Investment Company LLC. This strategic sale is designed to broaden the trust's unitholder base and facilitate its transition into the public domain.

Strategic Rationale for Conversion

The primary driver behind this conversion is the pursuit of greater financial flexibility and a more diversified investor base. By becoming a publicly listed entity, Cube Highways Trust aims to attract capital from institutional investors such as mutual funds, insurance companies, and pension funds. Historically, these investors have had limited participation in privately listed InvITs, often due to concerns about liquidity. A public listing is expected to address these constraints, opening up new avenues for capital raising and improving the trading profile of the trust's units.

Company Profile and Portfolio

Cube Highways Trust is a prominent player in India's highways sector, operating and managing projects under the public-private partnership (PPP) model. The trust is backed by a consortium of globally recognized investors, including I Squared Capital, the Abu Dhabi Investment Authority (ADIA), British Columbia Investment Management Corporation, and Mubadala Investment Company. As of September 2025, the trust reported a substantial Asset Under Management (AUM) of ₹36,520 crore.

Its portfolio at that time consisted of 27 road assets spread across 12 states and one union territory. The asset mix is diverse, including 18 toll roads, six hybrid annuity model (HAM) projects, and three annuity assets.

Planned Portfolio Expansion

In a move to further strengthen its asset base ahead of the public offering, the trust plans to acquire four additional highway and tunnel project Special Purpose Vehicles (SPVs) through swap transactions. This acquisition will increase its total portfolio to 31 road assets, covering an extensive network of 9,811 lane kilometers. This expansion underscores the trust's strategy of scaling its operations and enhancing its revenue-generating capacity before approaching the public market.

Market Context and Regulatory Support

Cube Highways' move to go public is well-timed with a supportive regulatory environment. SEBI has been actively working on reforms to make it easier for private InvITs to convert into public ones. Proposed changes include easing sponsor contribution norms and shortening lock-in periods for unitholders. These regulatory tailwinds are expected to unlock significant capital for India's infrastructure sector by creating a more streamlined path to public markets. The Indian InvIT market is projected to see substantial growth, with AUM expected to reach ₹8 lakh crore by FY2027, driven largely by the roads sector.

Lead Managers and Trustee

A consortium of leading financial institutions has been appointed to manage the offer. The book-running lead managers include Kotak Mahindra Capital Company, HDFC Bank, HSBC Securities and Capital Markets (India) Private Ltd, and JM Financial. Axis Trustee Services will act as the trustee for the offer.

Broader Industry Impact

This proposed conversion is a landmark event that could set a precedent for other privately held InvITs in India. A successful transition by Cube Highways could encourage other players to tap into public markets, thereby deepening the capital market for infrastructure assets. It represents a maturation of the InvIT model in India, shifting from a reliance on private institutional capital towards a more inclusive structure that allows broader public participation. This could significantly change how long-term infrastructure projects are financed in the country.

Conclusion

Cube Highways Trust's filing for a ₹5,000 crore OFS is a pivotal step in its journey and a significant milestone for the Indian InvIT sector. By becoming the first private InvIT to transition to a public listing, it aims to enhance liquidity, diversify its investor base, and unlock new growth opportunities. The success of this offering, supported by favorable regulatory reforms, will be closely watched as it could pave the way for a new wave of infrastructure financing through public markets in India.
