Approach 1: Southern Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow (DCF) model estimates a company's intrinsic value by projecting future cash flows and discounting them back to today's value, giving investors a sense of what the business is fundamentally worth.

For Southern, the DCF uses the Two-Stage Free Cash Flow to Equity model based on projections for the next decade. Currently, Southern's last twelve months' Free Cash Flow stands at negative $1.01 Billion, highlighting near-term cash outflows. According to available estimates, Free Cash Flow is expected to rebound over the coming years, reaching $2.10 Billion by 2027. These five-year analyst forecasts are extended by Simply Wall St to cover ten years, with the model projecting an impressive $19.45 Billion Free Cash Flow in 2035.

After discounting all these projected future cash flows to their present value, the model calculates an intrinsic value per share of $294.33. With Southern's current trading price, this suggests the stock is trading at a 68.8% discount to its calculated fair value. This implies it is significantly undervalued at this moment.

Result: UNDERVALUED

Approach 2: Southern Price vs Earnings

The Price-to-Earnings (PE) ratio is a popular metric for valuing profitable companies like Southern because it directly connects the company’s share price with its earnings power. A lower PE can be a signal that a stock is undervalued relative to its earnings, while a higher PE may reflect expectations of growth, stability, or lower risk.

When comparing PE ratios, it is important to consider both growth expectations and perceived risk. Fast-growing or lower risk utilities can sustain higher PE ratios, while slower growers or riskier firms should trade at a discount.

Southern is currently trading at a PE ratio of 22.7x, just below its peer group average of 26.3x and above the Electric Utilities industry average of 21.0x. On the surface, this positions Southern as reasonably valued in its sector, but focusing only on these benchmarks can miss the nuances of each business.

Simply Wall St’s Fair Ratio, which incorporates factors like Southern's earnings growth, profit margins, market cap, industry, and business risks, suggests a fair PE of 23.3x. This proprietary ratio provides a more precise valuation "target" than simply looking at average multiples. By tailoring expectations to the company’s profile, it captures the bigger picture for what investors should actually pay.

With Southern’s actual PE (22.7x) almost matching its Fair Ratio (23.3x), the stock appears very close to fair value on earnings.

Upgrade Your Decision Making: Choose your Southern Narrative

Earlier we mentioned that there's an even better way to understand valuation, so let's introduce you to Narratives. A Narrative is your personal take on a company's story, combining your assumptions about its future revenue, earnings potential, and margins to map out what you believe the business is truly worth. By linking the company's story with a clear financial forecast and a resulting fair value, Narratives go beyond the numbers to help you decide when to buy or sell.

On Simply Wall St's platform, millions of investors use Narratives on the Community page to transparently state their views, compare against others, and adjust as new information like earnings or news is released. Narratives are dynamic and automatically update their fair value when events impact the story, ensuring your assessment stays current.

For Southern, some investors' Narratives might be shaped by confidence in robust revenue growth and improved margins resulting in a high price target of $108, while others with concerns about regulatory or cost risks might see fair value closer to $75.

Narratives make valuation accessible, personalized, and adaptable, empowering you to make smarter decisions based on both your perspective and real-time developments.
