This definitive agreement follows the non-binding offer exchanged on May 14, 2026, and marks a significant milestone in the Company’s capital recycling strategy, successfully scaling up its publicly listed infrastructure investment trust portfolio. The Board of Directors of the Investment Managers of both the entities have agreed to proceed with the deal at their respective Board Meetings held today. IRB will be the Project Manager of aforesaid two BOT projects, post transfer to IRB InvIT Fund. This will increase Company’s O&M order book by approx. Rs. 2,400Crs. Commenting on the development, Mr. Virendra D. Mhaiskar, Chairman & Managing Director of the Company said, “The signing of this binding term sheet represents another successful iteration of IRB’s B.E.S.T. (Bid, Execute, Stabilize, Transfer) strategy, underscoring the strength of our capital recycling model. By periodically monetizing mature assets and redeploying the released capital through the Private InvIT into new opportunities, we are creating a self-sustaining growth platform that compounds shareholder value without incremental equity infusion at the sponsor level. The transaction strengthens both InvITs by enhancing Public InvIT’s portfolio with seasoned high- quality, revenue-generating assets and a longer weighted average concession life while replenishing the Private InvIT’s capital for future acquisitions and development. This scalable model cements IRB’s transition into a premier Sponsor and O&M platform accelerating our progress towards building an asset base of ₹1,40,000 crore over the next three to four years.” Two BOT Projects to be transferred under the deal from IRB Infrastructure Trust to IRB InvIT Fund are - Sr. No. Asset Name Mode Lane Kms 1 Solapur Yedeshi NH211 (Maharashtra) BOT 395 2.
