Shares of Arisinfra Solutions Ltd rose to a day high of Rs 133.00 on 29 September after it agreed to raise its Buildmex-Infra stake to 92%.

The board cleared the deal at its meeting on 28 September. Arisinfra will pay Rs 60 crore in cash for 16,000 shares of Buildmex-Infra Private Limited, a construction materials supplier, held by Balavignesh Subramani.

That takes its holding from 76% to 92%. The purchase should close on or before 30 September. The seller is not related to Arisinfra. No government approvals are needed.

Buildmex-Infra was incorporated in July 2021. It trades and supplies raw materials for infrastructure projects and buildings. Turnover has climbed fast, from Rs 17.93 crore in FY24 to Rs 70.36 crore in FY25 and Rs 179.03 crore in FY26.

That is roughly a tenfold jump in two years. Going by the price paid, the deal values the whole company at about Rs 375 crore.

Chairman and Managing Director Ronak Morbia said the higher stake lets shareholders capture more value from a business with room to grow. Cash stays put, the firm says, because trade deposits and advances will fall by the same Rs 60 crore.

The board also backed a Rs 20 crore guarantee for debentures, a form of debt, that Lionheart Trading Private Limited plans to issue in favour of Texterity Private Limited.

Lionheart, earlier called Arisinfra Trading, is a wholly owned arm. The guarantee is a contingent liability, meaning Arisinfra pays only if Lionheart cannot, and the company sees no impact for now.

For FY26, Arisinfra’s revenue from operations rose 39.1% to Rs 1,067.46 crore. At 10:59 am, Arisinfra Solutions was trading at Rs 133.00 on NSE, up Rs 0.39 or 0.29% from Monday’s close of Rs 132.61.

The day’s low was Rs 129.33. It’s up 3.60% this year but has lost 12.10% in a month, and sits well below its 52-week high of Rs 178.30.
