## Exhibit 99.1

![](image_001.jpg)

**Ecopetrol Group to Invest Between COP 22 and 27 Trillion in 2026**

Ecopetrol S.A. (BVC: ECOPETROL; NYSE: EC) ("Ecopetrol" and together with its subsidiaries, the "Ecopetrol Group") announces that its board of directors has approved the Ecopetrol Group's Annual Investment Plan for 2026 (the "2026 Annual Investment Plan"), with an amount ranging between COP 22 and 27 trillion<sup>[1]</sup>. This plan maintains investment levels compared to the projected 2025 year-end figures, under capital discipline criteria for each business line, and includes the following guidelines:

&nbsp;&nbsp;&nbsp;&nbsp;· Approximately COP 17.2 trillion, about 70% of the budget, is expected to
be allocated to profitably produce between 730 and 740 thousand barrels of oil equivalent per day, maintain an average refinery throughput
of 410 to 420 thousand barrels per day, and transport between 1,110 and 1,120 thousand barrels per day.

&nbsp;&nbsp;&nbsp;&nbsp;· Around COP 7.1 trillion, approximately 30% of the budget, is expected to
be invested in Energy Transition and Power Transmission projects, as well as roads and other corporate investments.

&nbsp;&nbsp;&nbsp;&nbsp;· The 2026 Annual Investment Plan considers a challenging environment, with
an estimated Brent price of US$60 per barrel and an average annual exchange rate close to COP 4,050. Accordingly, Ecopetrol Group has
defined a strategy to safeguard profitability and liquidity through cost reductions, enabling an approximate EBITDA margin of 40%, in
line with 2025 levels. Additionally, transfers to the Nation are estimated at around COP 28 trillion.

&nbsp;&nbsp;&nbsp;&nbsp;· The Profitability and Efficiency Program is expected to contribute approximately
COP 5.7 trillion, positively impacting EBITDA, investments, and working capital. The program is also expected to support performance in
total refining costs, transported barrel costs, and maintain lifting costs below US$12 per barrel.

&nbsp;&nbsp;&nbsp;&nbsp;· About COP 1.7 trillion is expected to be allocated to advance the goals
of the sustainability strategy (SosTECnibility), mainly in climate change, sustainable territories, materials and waste, and occupational
health.

&nbsp;&nbsp;&nbsp;&nbsp;· To safeguard cash and maintain healthy debt and profitability metrics, the
Ecopetrol Group expects to implement a portfolio rotation program.

**Highlights by Business Line:**

**Hydrocarbons Line**

<br> Investments in exploration and production is expected to amount to COP 14 trillion (89% for crude oil and 11% for gas), focused on achieving organic production levels of 730–740 thousand barrels of oil equivalent per day (80% crude, 15% gas, 5% white products) through recovery technologies to optimize resources and sustain production. Crude oil output in Colombia is expected to increase, offsetting natural gas field declines.

The Ecopetrol Group plans to drill between 380 and 430 development wells, 95% in Colombia and 5% in the U.S. Additionally, 8 to 10 exploratory wells are planned in Colombia, mainly offshore, Meta, and Putumayo. Gas investments are estimated at COP 1.5 trillion, primarily in the Llanos Foothills and offshore areas to develop Caribbean gas and contribute around 105–110 thousand barrels of oil equivalent per day.

Transport investments are expected to total about COP 1.5 trillion (6% of the budget), mainly for integrity and reliability projects by Cenit, Ocensa, ODC, and ODL. Transported volumes are expected to range between 1,110 and 1,120 thousand barrels per day, aligned with national production and refined product demand.

Refining investments are expected to be close to COP 1.7 trillion (7% of the budget), focused on ensuring reliability, availability, and sustainability at the Barrancabermeja and Cartagena refineries, reducing product imports, and improving fuel quality (LBCC<sup>[2]</sup>). Combined refinery throughput is expected between 410 and 420 thousand barrels per day.

**Transmission and Roads Line**

<br> Interconexión Eléctrica S.A. E.S.P. (ISA), an Ecopetrol subsidiary, is expected to invest between COP 6.2 and 6.8 trillion in 2026, about 26% of the Ecopetrol Group's annual budget, with roughly 80% allocated to the electric transmission business.

**Energy Transition Line**

<br> To advance energy transition, around COP 0.9 trillion (3% of the plan) are expected to be invested in non-conventional renewable energy and energy efficiency projects, among others. Approximately 750 MW of additional clean energy generation capacity is expected from projects in operation, construction, and development.

Finally, the Ecopetrol Group expects to allocate about COP 0.2 trillion (1% of the plan) to corporate areas and operational support.

**In summary**, the 2026 Annual Investment Plan presented by Ecopetrol Group includes investments across all business lines and operational efficiencies to sustain production levels, safeguard cash, and maintain long-term debt and profitability metrics, even under challenging market conditions.
