Most Popular Narrative: 25.9% Undervalued
Against the current CA$17.38 share price, the most followed narrative for TransAlta points to a fair value of CA$23.45, which implies meaningful upside in the valuation story investors are using to frame the stock.
Rising electricity demand from electrification (including data centers and broad energy transition themes) and tightening supply demand balances in key markets like Alberta and Ontario are creating favorable recontracting environments and potential for higher realized prices, directly enhancing revenue and EBITDA over the medium to long term.
The fair value hinges on a specific playbook: steady revenue assumptions, a clear path to higher margins, and a future earnings profile that supports a much richer multiple than today. The big question is how firmly you believe those inputs.
Result: Fair Value of CA$23.45 (UNDERVALUED)

Another View on TransAlta Using Sales Multiples
The narrative fair value of CA$23.45 paints TransAlta as 25.9% undervalued, yet the P/S ratio tells a more cautious story. At 2.4x sales, the stock trades above an estimated fair ratio of 1.6x, even though it is slightly below both peer and broader North American renewable industry averages of about 3.1x and 2.5x. For investors, that mix of relative value and fair ratio premium raises a simple question: Is the upside case strong enough to justify paying more than what the fair ratio suggests the market could move toward over time?
