S&P Global Ratings Affirms Ecopetrol’s Global and Stand-Alone Credit Ratings Bogota D.C., June 16, 2026 Ecopetrol S.A. (BVC:
ECOPETROL; NYSE: EC, the “Company”) informs that S&P Global Ratings (“S&P”) has affirmed the Company’s
global credit rating at BB- with a stable outlook, as well as Ecopetrol’s Stand-Alone Credit Profile (“SACP”) at bb+.
The credit rating reflects S&P’s assessment as of the date hereof and is subject to change at any time. A credit rating is not
a recommendation to buy, sell, or hold securities and may be revised or withdrawn by S&P at any time. With respect to the stand-alone
rating, S&P highlighted the Company’s continued strengthening of its liquidity sources, noting that Ecopetrol secured a committed
credit facility of approximately USD190 million, refinanced its short-term debt maturities, and has benefited from higher operating cash
flows. In addition, according to S&P, the Company is expected to maintain solid leverage metrics, with an adjusted net debt-to-EBITDA
ratio close to 2.0x over the coming years, supported by a favorable price environment and no significant debt increases in the short term.
These are S&P’s own estimates and do not necessarily reflect the Company’s internal estimates or guidance. According to
S&P, Ecopetrol’s stable outlook remains linked to that of the Republic of Colombia, reflecting the Company’s continued
importance to the Colombian economy and its close relationship with the Government of Colombia. The full report published by S&P is
available below: ------------------------------------- Ecopetrol is the largest company in Colombia and one of the main integrated energy
companies in the American continent, with more than 19,000 employees. In Colombia, it is responsible for more than 60% of the hydrocarbon
production of most transportation, logistics, and hydrocarbon refining systems, and it holds leading positions in the petrochemicals and
gas distribution segments. With the acquisition of 51.4% of ISA’s shares, the company participates in energy transmission, the management
of real-time systems (XM), and the Barranquilla–Cartagena coastal highway concession. At the international level, Ecopetrol has
a stake in strategic basins in the American continent, with drilling and exploration operations in the United States (Permian basin and
the Gulf of Mexico), Brazil, and Mexico, and, through ISA and its subsidiaries, Ecopetrol holds leading positions in the power transmission
business in Brazil, Chile, Peru, and Bolivia, road concessions in Chile, and the telecommunications sector. This release contains statements

PUBLICA Tear Sheet: Ecopetrol S.A. June 16, 2026 Primary Contact (Editor's Note: S&P Global Ratings believes there is a high
degree of unpredictability around the duration and scale of the Middle East war and its potential effect on commodity prices, supply chains,
economies, and credit conditions. As a result, our baseline forecasts carry a significant amount of uncertainty. As situations evolve,
we will gauge the macro and credit materiality of potential shifts and reassess our guidance accordingly.) Humberto Patino Mexico City
This report does not constitute a rating action. 5 2-55-50814485 humberto.patino spglobal.com We anticipate improved top-line performance
at Ecopetrol, driven by rising prices for oil, natural gas, and refined products. Based on S&P Global Ratings' assumption of $110
per barrel for the price of Brent crude oil for the remainder of 2026, we expect a 25%-30% jump in revenue. @ Secondary Contact We also
project that this price environment will bolster profitability, with the EBITDA margin expected to rise to about 46%. Strengthened cash
flows will continue to support exploration and production (E&P) investments, helping to offset declining production rates, particularly
in natural gas. Fabiola Ortiz Mexico City 5 2-55-5081-4449 fabiola.ortiz spglobal.com @ We expect continued strength in leverage metrics
as higher commodity prices persist. Given our expectation of no significant new debt over the next 12-24 months, our base case sees average
adjusted net debt-to-EBITDA ratios staying near 2.0x over the next three years. Notably, our current forecast excludes the Brava acquisition
until Ecopetrol secures its 51% stake. When it does, the acquisition would translate to increased production--by about 40,500 barrels
of oil equivalent per day (boepd). That's equivalent to 51% of Brava's total production of about 81,000 boepd. Ecopetrol continues to
bolster its liquidity sources. The company secured a roughly $190 million committed credit line, refinanced its short-term debt maturities,
and benefited from rising operating cash flows. This mitigates the delayed FEPC receivables from the government starting in the first
quarter of 2026 (from past-due settlements). Ecopetrol's stand-alone credit profile (SACP) is 'bb+', but the rating remains capped by
the foreign currency sovereign rating on Colombia. This cap reflects the company's very important role and strong link to the government;
while we expect timely state support during a period of stress, the government's influence over tax and dividend policies poses a potential
risk. An upward revision of the SACP would require a proven track record of robust leverage and resilient cash generation despite commodity
price volatility. www.spglobal.com/ratingsdirect June 16, 2026 1 Ecopetrol S.A. Ratings Score Snapshot Business risk: Satisfactory

Ecopetrol S.A.'s Planned Acquisition Of Brava Energia Would Expand Scale, Diversify Assets, April 24, 2026 Research Update: Ecopetrol
S.A. Downgraded To 'BB-' From 'BB' Following Similar Action On The Sovereign; Outlook Stable, April 8, 2026 Company Description Ecopetrol
is a vertically integrated oil and gas company based in Bogota, Colombia, and it also engages in power and infrastructure-related activities.
It has a presence in Colombia, Brazil, Mexico, the U.S. Gulf Coast, and Singapore, as well as in Chile, Peru, and Bolivia through Interconexión
Eléctrica S.A. Ecopetrol is involved in all stages of the hydrocarbon chain: exploration, production, refining, and marketing,
as well as the electric transmission business. The government of Colombia owns 8 8.49% of Ecopetrol, making it the controlling shareholder.
Institutional shareholders and retail investors own the remaining 11.51%. Outlook The stable outlook on Ecopetrol remains tied to that
on Colombia, reflecting the company's continued importance to the Colombian economy and its strong relationship with the government. As
a result, we expect our ratings on Ecopetrol to move in line with those on the sovereign. Downside scenario We could take a negative rating
action on Ecopetrol in the next 12 months if we were to take a similar action on Colombia. We could revise Ecopetrol's SACP down in the
next 12 months if: www.spglobal.com/ratingsdirect June 16, 2026 2 Ecopetrol S.A. • Its financial performance weakens such that
we expect its adjusted net debt to EBITDA to consistently rise to close to 3.0x (this could stem from lower prices, weaker production
sales, or increased debt beyond our expectations); • • We perceive weaker business for Ecopetrol if it posts declines in production
or replacement ratios below 100%; or Ecopetrol prioritizes cash outflows as dividends rather than for maintenance and growth capital expenditure
(capex). Upside scenario We could take a positive rating action on Ecopetrol if we were to take a similar action on the long- term foreign
currency sovereign credit rating on Colombia. Although it's unlikely within the next 12 months, we could revise up Ecopetrol's SACP to
'bbb-' if the company's operating and financial performance is well above our expectations. This could happen if: • • •
• Ecopetrol has higher-than-expected production stemming from investments in Colombia or international fields; It has debt-to-EBITDA
ratios below 2.0x while improving profitability margins despite price volatility; It improves cash flows after capex and dividends, leading
to discretionary cash flow to debt at or above 15%; or There are more independent board members and the company improves board member
turnover. Key Metrics Ecopetrol S.A.--Forecast summary Period ending Dec-31-2024 2024a Dec-31-2025 2025a Dec-31-2026 2026e Dec-31-2027
