ISA Full-Year 2025 Net Income Dips 14% Year-on-Year
Medellin-based international electric-power transmisión, highways and telecom-internet operator ISA announced March 2 that its full-year 2025 net income declined 14% year-on-year, to COP$2.4 trillion (US$633 million), from COP$2.8 trillion (US$680 million) in 2024.
ISA blamed the 2025 profits decline on “extraordinary and non-recurring events” including changes in power payment rules in Brasil and Peru as well as a loan-loss provision for transmitting power to Colombia’s failed “Air-e” electric utility on the Atlantic coast.
Despite the 2025 profits decline, consolidated revenues in 2025 rose 1.2% year-on-year, to COP$16 trillion (US$4.2 billion), from COP$15.8 trillion (US$3.8 billion) in 2024.
Earnings before interest, taxes, depreciation and amortization (EBITDA) for 2025 dipped 11% year-on-year, to COP$8.7 trillion (US$2.3 billion), while return on equity in 2025 came-in at 14%, according to the company.
Excluding the cited extraordinary events, “EBITDA associated with operations would close at COP$9.6 trillion [US$2.5 billlion], growing 8% compared to December 2024, mainly due to new projects that came online and generated more revenue for the businesses, [along with] the positive effect of contractual escalators, concession returns, and higher income from maintenance contracts on our highways businesses,” according to the company.
Also during 2025, “ISA executed investments of COP$6.3 trillion [US$1.66 billion], representing a 31% increase compared to 2024,” according to the company. “Over the next five years, the company will execute investments of COP$25.5 trillion [US$6.7 billion],” ISA added.
