TransAlta Q2: Strong Execution Through Temporary Headwinds

Summary TransAlta Corporation remains a buy, supported by resilient Q2 results despite low Alberta energy prices and climate-driven hydro declines. TAC's contract management insulated earnings, securing average prices of $121/MWh versus $29/MWh spot, and reaffirmed 2026 EBITDA guidance of CAD 950M–1.05B. I see TAC as a strategic long-term play on AI-driven electrification, with mid-cap utilities poised for re-rating as energy demand accelerates. Current valuation at 14x EV/EBITDA and recent price weakness present an attractive accumulation opportunity, with medium-term upside potential toward $18. Read the full article on Seeking Alpha

TransAlta: Cratering Alberta Power Prices Offset By Option Premiums

Summary We were exiting our TransAlta position at the time we last wrote about it. The stock has roundtripped back to the same point. The setup seems similar, but there is a much bigger margin of safety today. We tell you why we think the common with covered calls, generating 25% yields, is better than the preferred.

TransAlta's Growth Story Has Holes And I'm Not Buying It

Summary TransAlta Corporation faces a challenging year with a 20% stock decline, weak grades, and Alberta’s collapsing power prices impacting revenue stability. Despite market headwinds, TransAlta’s efficiency, strategic acquisitions, and expansion in renewable energy projects bolster its long-term growth potential. The company maintains strong free cash flow and liquidity, with significant investments in data centers and renewable energy projects supporting future growth. Given regulatory uncertainties and declining earnings, I rate TransAlta as a hold, pending stabilization of earnings and successful execution of growth initiatives.

TransAlta: The Transition Must Accelerate

Summary TransAlta is a Canadian power producer, still generating the majority of revenues from fossil fuels but with an important pipeline of renewables plants under development. Its hybrid structure could make it a good investment opportunity in the transition to clean energy, with the thesis supported by the result of my DCF model. However, three major risks are at stake: high dependence on electricity prices, large revenues concentration in Alberta and delays in construction of renewable projects.
