Talen Energy scores just 2/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.
A Discounted Cash Flow (DCF) model estimates a company’s intrinsic value by projecting its future cash flows and discounting them back to today’s dollars. This approach helps investors evaluate what a business is truly worth based on its ability to generate cash in the future.
Talen Energy currently reports Free Cash Flow of $162.7 Million. Analysts project significant growth in the years ahead, with Free Cash Flow expected to reach $1.96 Billion by the end of 2029, based on a mix of analyst and extrapolated forecasts. The DCF model here uses a 2-Stage Free Cash Flow to Equity approach. This method captures both short-term analyst estimates up to five years and longer-term trends projected by Simply Wall St.
By discounting these future values to the present, the estimated fair value for Talen Energy is $1,074.30 per share. This compares to a current market price that, according to the model, implies the stock is 63.3% undervalued. This significant discount suggests the market may be underestimating Talen Energy’s future earnings power and growth potential.
Result: UNDERVALUED
Our Discounted Cash Flow (DCF) analysis suggests Talen Energy is undervalued by 63.3%. Track this in your watchlist or portfolio, or discover 917 more undervalued stocks based on cash flows.
The Price-to-Earnings (PE) ratio is one of the most widely used valuation metrics for profitable companies because it directly relates a company’s share price to its earnings per share, offering a snapshot of what investors are willing to pay for current or future profits. It is particularly useful when businesses consistently generate positive earnings, as is the case with Talen Energy.
Interpreting a PE ratio involves more than just looking at the number itself, as it often reflects growth expectations and perceived risk. Companies with strong growth prospects or lower risk profiles tend to command higher PE ratios. Firms facing uncertainty or slow expansion usually trade at lower multiples.
Talen Energy currently trades on a PE ratio of 79.7x, which is substantially above both the renewable energy industry average of 17.2x and the average of its listed peers at 28.8x. At first glance, this might raise questions about whether the stock is priced for perfection or simply outpacing the competition.
However, looking beyond the raw numbers, the proprietary “Fair Ratio” developed by Simply Wall St provides a more tailored benchmark. The Fair Ratio for Talen Energy is 58.1x, factoring in specifics like its earnings growth profile, profit margins, business risks, market cap, and its industry landscape. Unlike basic peer or industry comparisons, this custom metric helps investors gauge what a reasonable multiple should be for this unique business, taking into account both potential and pitfalls.
Comparing Talen Energy’s actual PE of 79.7x to its Fair Ratio of 58.1x, the stock appears overvalued relative to what would be justified for its growth and risk profile. This suggests that much of the optimism is already priced in, and current investors may be paying a premium to own shares at today’s valuation.
Result: OVERVALUED
