Cube Highways Trust IPO: ₹5,000 crore OFS in 2026

What is happening and why it matters

Cube Highways Trust is preparing for a public market listing through an initial public offering sized at up to ₹5,000 crore. The entire issue is structured as an offer for sale (OFS), meaning existing unitholders will sell units to new investors and the trust will not raise fresh capital through the IPO. People familiar with the matter said the transaction is intended to broaden the investor base and improve liquidity in the units after listing. The move also marks a conversion from a privately listed Infrastructure Investment Trust (InvIT) to a publicly listed InvIT. Cube Highways Trust has started roadshows, reaching out to a select set of domestic and overseas institutions before pricing is decided. The trust is expected to list its units on NSE and BSE.

Offer structure: a pure offer-for-sale

The draft papers describe the proposed issue as an OFS of units aggregating up to ₹5,000 crore. Under this structure, the IPO functions primarily as a liquidity event for existing investors rather than a fundraise for the trust. The selling unitholders named include Cube Highways and Infrastructure II, Cube Highways and Infrastructure III, Cube Mobility Investments, BCI IRR India, and Seventy Second Investment Company. The trust’s stated purpose, as described by sources, is to expand participation in its units and increase trading liquidity post listing. Because there is no fresh issue component mentioned, the trust’s balance sheet does not receive new capital from the IPO proceeds. For investors, the key decision factors typically shift toward portfolio quality, cash flow profile, and governance, rather than primary capital deployment.

Roadshows and timing: October targeted, subject to demand

Cube Highways Trust has kicked off roadshows as it prepares for the IPO, with people familiar with the matter indicating an October launch target. The schedule could shift depending on investor demand during the roadshow process. An investment banker involved in the transaction said volatility in the primary market is receding and that there is a more stable window for large-scale institutional fundraising. The same person added that although the Draft Red Herring Prospectus (DRHP) was filed in March, it was important to wait out a few uncertain months before increasing investor outreach. The trust is engaging with a select set of domestic and overseas institutions ahead of pricing decisions. Separately, the broader IPO pipeline remains active, with SEBI also clearing three mainboard IPOs: Torrent Gas, Kanohar Electricals, and Sathya Agencies.

Regulatory filing and named intermediaries

Cube Highways Trust filed its draft offer document with SEBI on March 17, 2026, starting the regulatory process for conversion and listing. The filing describes Cube Highways Trust as a privately listed InvIT proposing conversion to a public InvIT through an OFS. The book-running lead managers named for the offer are Kotak Mahindra Capital Company, HDFC Bank, HSBC Securities and Capital Markets (India) Private Ltd, and JM Financial. Axis Trustee Services is the trustee. KFin Technologies Limited is named as the registrar in material circulated about the proposed offering. The units are expected to be listed on the NSE and BSE, as per the details provided.

Scale: market capitalisation and portfolio footprint

The trust is being positioned as a large infrastructure investment platform, with a market capitalisation mentioned at around ₹20,400 crore. Its asset portfolio is valued at ₹36,520 crore across 27 highways, as stated in the provided information. As of September 2025, the trust manages assets worth approximately ₹36,520 crore, spread across 27 operational road projects in 12 states and one union territory. This footprint matters for InvIT investors because diversification across geographies and projects can affect the stability of cash flows. The trust’s portfolio mix is also described with a revenue split of 85% toll and 15% annuity. That mix can influence sensitivity to traffic trends and the predictability of distributions.

Planned acquisitions before listing

Ahead of the public listing, Cube Highways Trust plans to acquire four additional highway and tunnel projects through swap transactions. This is expected to take the total asset base to 31 projects. The expansion is also described in terms of lane length, with a target of 9,811 lane kilometres. Another reference describes this as nearly 9,800 km, reflecting an approximate figure around the same level. These additions, if completed as described, would change the scale of the portfolio that investors are evaluating during the IPO process. The information provided does not specify the individual assets or timelines for completing the swap transactions beyond being “before the IPO is completed.”

Why a public InvIT conversion is notable

The transaction is framed as a shift from a privately listed InvIT structure to a publicly listed InvIT. People familiar with the matter described this as a first-of-its-kind move in India’s infrastructure investment trust space at this scale. In practical terms, a public listing is being pursued to increase the breadth of ownership and to improve liquidity in units through exchange trading. The OFS format aligns with this objective by enabling existing institutional holders to partially monetise their holdings. The trust is backed by global investors mentioned in the material, including I Squared Capital, Abu Dhabi Investment Authority (ADIA), British Columbia Investment Management Corporation (BCI), and Mubadala Investment Company. The offering is positioned as a route for current investors to potentially exit, while widening participation among new investors.

Key facts snapshot

Market impact: what investors will likely track

Because the issue is entirely an OFS, the immediate financial effect is centred on unit ownership and trading liquidity rather than capital inflow to the trust. Market participants typically focus on the quality and cash generation potential of the underlying roads, and how the toll and annuity mix affects cash flow stability. The roadshow process suggests the trust is seeking price discovery among domestic and overseas institutions, which may influence final pricing and allocation. The timing commentary points to improving primary market conditions, though the final launch window remains linked to investor demand. Investors may also track the proposed swap-based acquisitions, since portfolio additions would alter the scale and composition of assets being offered to the public market.

Conclusion

Cube Highways Trust’s planned IPO, sized at up to ₹5,000 crore, is built around a full offer-for-sale and a structural conversion into a publicly listed InvIT. Roadshows are underway, the DRHP has been filed with SEBI, and an October launch is being targeted, subject to demand. The offer includes established global backers among current unitholders and is aimed at expanding the investor base and improving unit liquidity. Next milestones will be progress in the regulatory process and the completion status of the proposed asset additions ahead of listing.
