• On December 14, ISA’s shareholders will receive the second dividend payment of the year (COP 651,5) per share.

• The dividend for the year approved by the Shareholder’s Meeting increased 93% compared with the 2020 dividend, the highest in the company’s history.

As approved by the Ordinary General Shareholders’ Meeting held on March 26, 2021, ISA must make the second dividend disbursement of COP 721.652 million as a result of the 1.107.677.894 ordinary shares outstanding.

The dividend approved by the Shareholders’ Meeting was the largest increase in ISA’s history -93% over the previous year-, corresponding to 70% of net income for 2020.

Those who hold their shares before December 7, 2021, the date on which the ex-dividend period begins and which runs until December 13, 2021, will be entitled to payment of the dividend.

The money corresponding to the unclaimed dividends does not generate any yield or interest. Therefore, it is important not to let it accumulate and obtain it on the payment established dates.
