Why is TransAlta Corporation (TAC) stock moving?
TransAlta reported Q3 2026 adjusted EPS of $0.13, well above the $0.05 estimate, but sales fell about 12.8% year over year to $383.0M, so the beat rests on profitability rather than revenue growth. The stock reacted on Nov 3-4 with volume running at roughly 2.1M and 3.5M shares, against about 0.8M-1.2M on quiet late-October days. Nov 4 hit an intraday high of 14.07 before the stock faded to 13.12 by Nov 5. Since then it has rebuilt, closing at 13.65 on Nov 9 before easing to 13.36 on Nov 10 on lighter volume of about 0.93M. From the Oct 23 close of 12.22, the shares are up roughly 9%, with late-October lows near 12.1-12.3 as a floor and the Nov 4 high near 14.07 as the nearest ceiling. The company also declared dividends on Oct 27, though the filing summary does not give the amount. The news flow is limited to one week of results coverage and filings, so the outlook beyond the next few weeks depends on the 2026 outlook in the MD&A and on how the sales decline develops.

About TransAlta Corporation
TransAlta is a Calgary-based power generator that owns gas, hydro, wind and solar plants across Canada, the United States and Western Australia, and is Alberta's largest hydro producer. It stands out for its large exposure to Alberta's deregulated power market and for plans to repurpose sites like Keephills (the "Boreal Technology Hub" data centre project) and its Centralia coal plant in Washington state.
How it makes money
It sells electricity and capacity. Some goes out under long-term contracts with utilities and industrial customers, and some is sold at market prices, mainly into Alberta's wholesale market. Hedging and energy trading smooth out swings in those prices, and environmental credits add some income. In October 2026 it bought gas plants in Colorado, which add contracted cash flow.
