IOL Chemicals hit its 20% upper circuit and a fresh 52 week high of Rs 173.35 on NSE after promoter stake rose to 62.28%.

According to the latest shareholding data, promoter ownership in the company rose to 62.28% as of June 2026, up from 57.48% at the end of March.

In simple terms, the people who run and control the company bought more shares themselves during the quarter, which markets often read as a strong vote of confidence from insiders.

This isn’t a one day story either. The stock has now risen in 11 of the last 13 trading sessions, gaining close to 36% over that stretch.

More than three crore shares had changed hands by the afternoon session on Tuesday alone, well above the stock’s usual trading volumes.

On the financial side, IOL Chemicals closed out the year on a high. In the March quarter, revenue rose 17.4% year on year to Rs 619.5 crore, its highest ever quarterly revenue.

EBITDA grew a sharper 39.8% to Rs 94.3 crore, with the margin expanding to 15.2% from 12.7%. Net profit jumped 68.2% to Rs 53.2 crore.

Management pointed to a better product mix and growing traction in non-Ibuprofen APIs as the main drivers behind the improvement.

By 14:28 pm, the stock had eased off its earlier high and was trading at Rs 166.72 on NSE, still up 15.41%, or Rs 22.26, from the previous close of Rs 144.46.
