Grupo Cibest director adds pension fund units

Vatnick Silvina reported acquisition or exercise transactions in this Form 4 filing.

Rhea-AI Filing Summary

Vatnick Silvina reported acquisition or exercise transactions in this Form 4 filing.

Grupo Cibest S.A. director Silvina Vatnick increased her indirect holding in a company-sponsored pension fund. On March 20, 2026, she was credited with 519.7800 additional units in the Grupo Cibest Equity Securities Fund at approximately $7.10 per unit, bringing her total to 24,382.8041 units.

The units are held in an institutional voluntary pension fund sponsored by Grupo Cibest and managed by an independent third party. The fund is unitized and invests mainly in Grupo Cibest common and preferred shares plus some cash. Vatnick has no voting or investment discretion over the fund’s assets, and the instrument has no expiration date. The units are payable solely in cash based on the fund’s value at withdrawal, so the exact number of Grupo Cibest shares economically attributable to these units will only be known when she redeems them.

Conversion rate is the proportion of items, people or contracts that take a desired action out of the total possible — for example the share of website visitors who make a purchase, or the number of convertible bonds that are exchanged for shares. Investors care because it measures how effectively a business or financial instrument turns opportunity into real outcomes, like sales or share issuance, which directly affects revenue, cash flow and ownership dilution.
