IRB Infra May 2026 toll jumps 25% to Rs 843 cr

Stock reaction and the trigger

IRB Infrastructure Developers’ shares rose 2.56% to Rs 21.20 after the company disclosed a sharp rise in toll collections for May 2026. The update covered the parent company along with its two sponsored Infrastructure Investment Trusts (InvITs). Toll revenue is a key operating indicator for IRB because it reflects traffic movement across its road portfolio and the performance of newly commissioned assets. The May numbers extended a run of higher monthly toll collections reported in the opening months of FY27. The disclosure also included management commentary pointing to traffic growth and the start of tolling on new projects.

May 2026 toll collections: the headline numbers

For May 2026, IRB reported toll collections of Rs 842.7 crore. This was a year-on-year increase of 25.30% from Rs 672.5 crore in May 2025. The same figures were also presented as Rs 8,427 million for May 2026 versus Rs 6,725 million for May 2025, which converts to the same Rs 842.7 crore and Rs 672.5 crore respectively. The increase indicates stronger traffic momentum across the portfolio, alongside incremental contribution from assets that have begun tolling recently.

Management commentary on growth drivers and risks

Amitabh Murarka, Deputy CEO, linked the May 2026 growth to continued traffic expansion across projects and the impact of tolling commencement on newly operational assets. He also pointed to a strong economy as a support for traffic, while acknowledging rising inflation amid ongoing geo-political unrest as a factor to watch. The company said it remains confident of sustaining the growth momentum in the coming months. The statement did not provide a project-wise split for May, but it reiterated the broad drivers behind the year-on-year rise.

Portfolio scale: assets, concession life, and traffic volumes

IRB said it manages a portfolio of 28 revenue-generating highway assets. The portfolio has an average residual concession life of 21 years, which matters for long-duration cash flows from tolling. Traffic volumes have averaged 1.5 million daily vehicle crossings across its network, underscoring the scale of usage across its assets. Separately, the company also highlighted its track record of constructing, tolling, operating, and maintaining around 19,000 lane km across India over more than 25 years.

Newer operational assets adding to collections

The May update referenced support from tolling commencement on newly operational assets, and the broader context mentioned recent additions contributing to revenue. Projects cited as additions that have started contributing include IRB Harihara Corridors, IRB Chandibhadra Tollway, and the Meerut Budaun Expressway. In earlier disclosures around April 2026, the company had detailed that toll collections began on IRB Harihara Corridors Tollway Pvt Ltd on January 23, 2026. It also said tolling commenced on IRB Chandibhadra Tollway Ltd from April 1, 2026. These starts help explain why year-on-year growth can remain elevated even beyond pure traffic growth on the existing base.

April 2026 context: another strong month

IRB and its InvITs had reported toll collections of Rs 793.5 crore for April 2026, up 24% year-on-year from Rs 641.8 crore in April 2025. The company attributed April’s growth to traffic growth, tariff revisions from April 1, and the addition of assets to the portfolio. It also disclosed that, on a like-to-like basis, growth was around 11% for April, with management indicating 2% to 3% contribution from tariff and around 8% to 9% from volume growth across the portfolio. Two recently operational projects were quantified for April: IRB Harihara Corridors reported Rs 57.2 crore and IRB Chandibhadra reported Rs 23.7 crore.

Full-year FY26 reference points and market share

In the broader set of disclosures included in the provided text, IRB Group’s annual toll revenue for FY26 was stated at Rs 8,323 crore. The company also cited that this represented about 10% market share of India’s toll revenue for FY26, with India’s total toll revenue stated as Rs 82,900 crore. These numbers provide context for IRB’s position in the toll-road ecosystem and why monthly toll collection trends are closely tracked by investors.

Key figures at a glance

Market impact: what investors tend to read into the update

The immediate market response was positive, with the stock rising 2.56% to Rs 21.20 after the May update. For IRB, sustained toll growth can signal stronger operating cash generation across its road assets, particularly when driven by both traffic and the ramp-up of newly operational projects. At the same time, management’s mention of inflation and geo-political unrest highlights that cost pressures and broader economic conditions remain relevant watch points. The company’s disclosures across April and May also indicate that a portion of growth can come from tariff revisions and portfolio additions, not just underlying traffic.

Why the May print matters for IRB’s FY27 start

May’s 25.30% year-on-year growth followed April’s 24% rise, suggesting a strong opening to FY27 based on the data shared. The company’s commentary consistently links the momentum to traffic trends, tariff changes implemented from April 1, and the contribution of newer assets coming into the tolling pool. With 28 revenue-generating highway assets and long concession lives, monthly toll performance is a key datapoint for monitoring how quickly projects scale after tolling begins. Future updates will likely be watched for confirmation on whether traffic growth remains steady and how much incremental revenue comes from newly operational corridors.

Conclusion

IRB’s May 2026 toll collections of Rs 842.7 crore, up 25.30% year-on-year, reinforced the strong start to FY27 highlighted by April’s numbers. Management cited traffic growth and new operational assets as key drivers, while flagging inflation as a factor to monitor. The next set of monthly disclosures should help investors assess whether growth remains broad-based across the portfolio and how recently started tolling assets continue to add to collections.
