Ecopetrol’s ADRs (EC) are down about 4.29% as the stock trades ex-dividend on Wednesday, April 29, 2026. On the ex-dividend date, new buyers no longer receive the upcoming cash dividend, and the share price often adjusts lower by roughly the dividend amount as the payout value is removed from the stock.

Market dividend calendars show an ex-dividend date of April 29, 2026 for Ecopetrol’s latest distribution, with an indicated cash dividend of roughly $0.66 per ADR and a scheduled payment date of May 7, 2026. Investors who owned shares before the ex-date (and meet settlement rules) typically remain eligible for the payment, while buyers on or after the ex-date generally do not.

With the dividend now “stripped out” of the stock, traders often look to near-term catalysts such as upcoming earnings timing and macro oil-price swings for the next directional push. Any updates on operating performance, capital returns, or Colombia-related policy and governance headlines can also amplify moves in the ADR beyond the mechanical dividend adjustment.
