Celsia S.A. E.S.P.

What it is

Celsia generates, transmits, distributes and sells electricity to residential, commercial, industrial and public customers in Colombia and Central America, operating hydroelectric, solar, wind and thermal plants. Its installed capacity exceeds 1,700 megawatts, spanning thermal stations and hydroelectric facilities.

The company was formerly known as Compañía Colombiana de Inversiones S.A. E.S.P. and was founded in 1919, headquartered in Medellín, Colombia.

It operates two business arms: energy services (generation, distribution, commercialisation) and asset management through third-party investment platforms in solar, transmission and thermal energy.

Who owns it

Grupo Argos S.A. holds 52.93% of Celsia’s subscribed and paid capital, establishing formal legal control under Colombian corporate law. Grupo Argos is one of Colombia’s largest investment holding companies, with a consolidated asset portfolio of approximately COP 51 trillion (US$14.8 bn), also owning 49% of Cementos Argos and 99.8% of infrastructure concessionaire Odinsa.

Celsia’s share capital is divided into 1,069,972,554 ordinary shares, and Colombian pension and severance funds are among its investors, meaning millions of ordinary Colombians share in the company’s returns. The government owns no more than 5% of the ownership structure.

Who runs it

Ricardo Sierra leads Celsia as its president — his voice has been the public face of its results and strategy, noting a 10-year average operating profit margin of 30% with swings during El Niño years. Esteban Piedrahita serves as the company’s chief financial leader (líder financiero), overseeing the balance sheet and capital allocation programme.

The board includes Ricardo Sierra Fernández, Esteban Piedrahita Montoya, Jesús Cadavid, Claudia Inés Salazar, Otto Elger and Simón Pérez — all linked to Grupo Empresarial Argos — who serve without remuneration for their directorial roles. The April 2026 statutory board period brought four new members following the retirement of Jorge Mario Velásquez, former Grupo Argos president.

The money, in plain words

In full-year 2024, Celsia collected COP 6.8 trillion (≈US$1.97 billion) in revenue — up 9.3% on 2023 — and earned a consolidated net profit of COP 337,000 million (≈US$97.8 million), down 3.3%. It kept about 5 cents of profit from every peso of sales — a net profit margin of ~5.0% (our calculation), modest for a utility because El Niño squeezed hydro output and forced costly thermal backup purchases.

The company closed the year carrying COP 5.51 trillion (≈US$1.60 billion) in consolidated debt, with a leverage ratio of 3.56 times net debt to operating profit — elevated but manageable given the long-lived nature of energy infrastructure. Financing costs fell sharply: the structural cost of debt dropped from 15.95% in December 2023 to 11.61% in December 2024, saving significant cash.

The 2024 dividend was COP 326 (US$0.09)per share — 5.2% more than the prior year — representing a yield of 8.9% against the share price at announcement, and sitting 455 basis points above Colombia’s expected 2025 inflation. The stock rewarded shareholders strongly: the share rose 24.3% during 2024, beating the MSCI Colcap index by 890 basis points, and with dividends included, total shareholder return reached 36.2%.

What it is doing now

In the first quarter of 2025, revenues rose 5.5% to COP 1.45 trillion (≈US$420 million) and operating profit (EBITDA) recovered 44.8%, as the return of rains after the El Niño drought sharply cut the need to buy expensive backup energy. Net profit for Q1 2025 jumped 264% to COP 108,064 million (≈US$31.3 million) compared with the same period in 2024.

Celsia is executing more than 1,000 MW of solar projects in Colombia and over 200 MW of wind projects in Peru — its first foray into that market — reflecting a deliberate pivot toward clean energy. Its C2 Energía solar platform (a joint venture with Cubico Sustainable Investments) grew revenues 46% in 2024 and has around 600 MW of solar capacity either operating or in advanced construction.

What to watch

• Hydrology risk: Celsia’s results are materially shaped by rainfall — the 2024 year was pressured by a longer-than-expected El Niño that generated instability across Colombia’s power sector. Wetter years flatter margins; dry ones punish them.
• Regulatory exposure: Colombia’s government has proposed tariff adjustments that could affect both Celsia’s distribution revenues and its generation returns — a live risk that management is navigating carefully.
• Solar & wind build-out: The Laurel small-solar platform (with Bancolombia Capital) has consolidated 134 photovoltaic systems totalling 51.5 MW and expects to reach a 100 MW target in half the originally planned time.
• Leverage trajectory: Net consolidated debt stood at COP 5.7 trillion (≈US$1.65 billion) at end of Q1 2025, with a net debt-to-EBITDA ratio of 3.49 times — a metric analysts and lenders will watch closely as new capital-intensive projects proceed.
• Share buyback: Celsia has invested more than COP 113,000 million (US$33 mn) in its buyback programme, completing 38% of the approved amount — a signal that management considers the current share price below fair value.
