Colbun first-half profit fell about 53 percent to US$60.9 million in the first six months of 2026, down from US$130.6 million a year earlier, as the Chilean power generator absorbed extraordinary costs tied to the early termination of coal supply contracts and navigated operational hurdles at its Peruvian unit.

First-Half Earnings Under Pressure
Chilean power generator Colbun, controlled by the Matte group, reported net profit of US$60.9 million for the first half of 2026. That represents a decline of roughly 53 percent from the US$130.6 million posted in the same period of 2025.
Earnings before interest, taxes, depreciation, and amortization (EBITDA) also weakened, reaching about US$290 million compared to approximately US$319 million in the first half of 2025, a drop of around 9 percent.
The company’s financial performance was dragged down by several factors. Extraordinary costs from the early termination of coal supply contracts were the primary driver, alongside higher financial expenses and operational difficulties in Peru.
At Colbun’s Peruvian subsidiary, Fenix, a gas-transport emergency forced the plant to switch from natural gas to higher-cost diesel. This fuel substitution compressed margins and contributed to the weaker consolidated EBITDA.
Second-Quarter Recovery Signals
Despite the difficult first-half comparison, Colbun’s second-quarter results showed a marked improvement. Q2 2026 EBITDA rose to about US$156.9 million, an increase of 12 percent compared to the same quarter a year earlier.
Quarterly revenue also climbed, reaching roughly US$449.2 million in the April-to-June period, up 12 percent year-on-year. The rebound suggests that the heaviest coal-exit charges may have been concentrated earlier in the year.
For foreign investors, the divergence between the first and second quarters is a critical detail. It indicates that while the decarbonization strategy carries significant upfront costs, underlying operational performance showed resilience in the second quarter.
Analysts will be closely monitoring the second half of 2026 to assess whether the recovery trajectory can be sustained or if additional contract termination charges will emerge.
The Cost of Decarbonization
The primary drag on Colbun’s first-half earnings was the cost of exiting coal contracts ahead of schedule. The company is actively unwinding these agreements as part of a broader push to decarbonize its generation matrix.
This strategy aligns with Chile’s national goal to retire all coal-fired power plants by 2040. For Colbun, the immediate financial impact is a significant cash outlay to terminate supply agreements early.
The company has not publicly detailed the exact cost of each contract termination. However, the impact is clearly visible in the first-half figures, where profit contracted sharply despite relatively stable operating conditions in its core markets.
Colbun is reinvesting in a renewable energy pipeline to replace the retired capacity. The Horizonte wind farm, now online, is a centerpiece of this transition, though its early-stage depreciation costs are currently a headwind on reported earnings.
Peruvian Operations Hit a Snag
Colbun’s international footprint includes its Peruvian subsidiary, Fenix. During the first half of 2026, Fenix faced an operational disruption that hurt its margins and contributed to the consolidated profit decline.
A gas transport emergency in Peru forced the plant to switch from natural gas to diesel. Diesel is a significantly more expensive fuel, which compressed the subsidiary’s profitability during the period.
The incident highlights the operational risks in Colbun’s regional diversification strategy. While Peru offers growth potential, its energy logistics infrastructure can be vulnerable to unexpected disruptions.
Colbun has not disclosed the full financial impact of the fuel switch at Fenix. However, the event was flagged in earnings materials as a contributing factor to the weaker half-year EBITDA.
Renewable Pipeline and Strategic Outlook
Beyond the immediate cost pressures, Colbun is building a portfolio of renewable energy projects. The Horizonte wind farm is the most advanced, having recently entered commercial operation and adding to the company’s clean-energy capacity.
The company’s decarbonization plan involves adding more wind, solar, and potentially energy storage capacity. These projects are designed to replace the earnings stream lost from retired coal plants over the long term.
Specific pipeline figures for Chile and Peru were not fully detailed in the available first-half commentary. Investors will need to review the full H1 2026 earnings presentation for a complete project-by-project breakdown.
The strategic narrative remains focused on a long-term transition. Colbun aims to emerge as a clean-energy leader in the Andean region, but the path involves near-term financial sacrifices like those seen in the first half of 2026.
What Foreign Investors Should Watch
For expatriates and international investors holding Colbun stock, the key metric is the pace of coal-contract exits. Future quarterly results may see similar lumpy charges as more agreements are terminated ahead of schedule.
Hydrological conditions in Chile are another variable. Colbun’s hydroelectric assets are sensitive to rainfall patterns, and a dry year can compound the financial strain from the coal exit and reduce hydroelectric output.
In Peru, the reliability of gas transport infrastructure is a risk to monitor. Any repeat of the diesel-switching event at Fenix would further drag on consolidated margins and test the resilience of the company’s regional diversification.
The long-term investment case hinges on successful execution of the renewable buildout. If Horizonte and future projects ramp up efficiently, they could offset the lost coal-fired earnings and justify the current transition costs.
Frequently Asked Questions
Why did Colbun’s first-half profit drop?
Colbun’s first-half 2026 net profit fell about 53 percent to US$60.9 million, down from US$130.6 million a year earlier.

How did Colbun’s Peru operations affect earnings?
Colbun’s Peruvian subsidiary, Fenix, was forced to switch from natural gas to more expensive diesel fuel due to a gas transport emergency. This fuel substitution hurt margins and contributed to the weaker consolidated EBITDA in the first half of 2026.
Is Colbun still investing in renewable energy?
Yes. Colbun’s decarbonization strategy includes new renewable projects like the Horizonte wind farm, which recently started commercial operations. The company is building a clean-energy pipeline to replace retired coal-fired capacity, aligning with Chile’s national goal to phase out coal by 2040.
