TransAlta Corporation reported its third‑quarter 2025 results, showing revenue of $615 million, a $234 million shortfall from the $849.1 million consensus estimate. Earnings per share were a loss of $0.02, versus the $0.0716 per‑share forecast, a miss of $0.0916 or 127.9 %. Adjusted EBITDA fell to $238 million, down from $315 million in the same quarter a year earlier, reflecting the impact of lower Alberta spot power prices and a tighter market environment.

The company’s operating mix remained unchanged, with hydro and wind‑and‑solar assets maintaining high availability, while the gas‑segment revenue was compressed by the decline in spot prices. TransAlta’s hedging strategy helped secure realized prices above the market, but the overall mix shift and lower market prices contributed to the EBITDA contraction. The company’s data‑center strategy continued to progress, with a 230 MW demand‑transmission service contract secured and land rezoning completed, positioning the firm for future growth in the data‑center market.

CEO John Kousinioris highlighted the company’s resilience, noting that hedging and asset optimization kept realized prices above spot levels and that availability remained high across the fleet. He also announced his retirement effective April 30, 2026, with CFO Joel Hunter slated to succeed him. The leadership transition underscores the company’s focus on continuity while pursuing strategic initiatives such as the Centralia conversion to gas‑fired operations and the acquisition of Heartland Generation.

TransAlta’s guidance for 2025 remains unchanged, but the company is tracking toward the lower end of its Adjusted EBITDA range. The outlook reflects caution amid ongoing headwinds, including lower Alberta power prices and market volatility, while the company signals confidence in its long‑term strategy through hedging, asset optimization, and data‑center expansion.

The market reaction was negative, driven primarily by the earnings and revenue miss and the lower guidance trajectory. Investors weighed the company’s headwinds—lower spot prices, subdued market volatility, and increased operating costs—against its tailwinds, such as strong hedging performance, high asset availability, and progress on data‑center and Centralia initiatives. The overall sentiment reflects concern about short‑term profitability but recognition of the company’s strategic positioning for future growth.
