Approach 1: Southwest Airlines Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a business could be worth today by projecting its future cash flows and then discounting those back to a present value.

For Southwest Airlines, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in US$. The latest twelve month free cash flow stands at a loss of about US$992.9 million. Analysts provide explicit free cash flow estimates for the next few years, and Simply Wall St extends these into longer term projections, including around US$255.99 million in 2035, adjusted back to today’s dollars in the model.

Putting those projections together, the DCF output suggests an estimated intrinsic value of about US$12.68 per share, compared with the current share price of roughly US$40.21. On this basis, the model implies the stock is very expensive relative to those cash flow assumptions, with an intrinsic discount indicating it is 217.1% overvalued.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Southwest Airlines may be overvalued by 217.1%. Discover 62 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Southwest Airlines Price vs Earnings

For profitable companies, the P/E ratio is a useful yardstick because it links what you pay for each share to the earnings that business is currently generating. Investors generally accept paying a higher P/E when they expect stronger earnings growth or see lower risk, and a lower P/E when growth expectations are modest or risks feel higher.

Southwest Airlines currently trades on a P/E of about 44.78x, compared with an Airlines industry average of 8.74x and a peer average of 23.58x. On the surface, that points to a much richer pricing than the broader group. However, simple comparisons like these do not account for company specific factors such as earnings growth profile, profit margins, business size or risk characteristics.

To address that, Simply Wall St uses a proprietary “Fair Ratio” of 26.56x, which reflects the P/E investors might usually expect for Southwest Airlines given its earnings growth, industry, profit margin, market cap and identified risks. This Fair Ratio is more tailored than a straight peer or industry comparison because it is built around the company’s own fundamentals. Since the current P/E of 44.78x sits well above the Fair Ratio of 26.56x, the multiple based view suggests the shares are trading on an expensive earnings valuation.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Southwest Airlines Narrative

Earlier the analysis pointed to a richer P/E multiple and hinted at a better way to think about valuation, so this is where Narratives come in as your way to connect a clear story about Southwest Airlines with specific forecasts for revenue, earnings, margins and a fair value that you can regularly compare with the current share price.

A Narrative is simply your version of the Southwest Airlines story, written in numbers, where you spell out what you think happens to revenue growth, profit margins and future earnings, and then see what share price those assumptions line up with.

On Simply Wall St, Narratives are available on the Community page and used by millions of investors. This makes it easy to see how a particular story about cabin upgrades, new fees, fuel costs or demand trends translates into a financial model and a fair value estimate without needing to build spreadsheets yourself.

Because Narratives are linked to live data, they update when new information such as earnings releases, guidance changes or fresh news on fuel costs or product rollouts is added. Your fair value view keeps moving as the facts change rather than staying frozen at one point in time.

For Southwest Airlines, one Narrative might lean toward the more optimistic fair value around US$60.00 that assumes higher revenue growth and margins from new seating and fee initiatives. Another might lean closer to the more cautious fair value near US$24.03 that puts more weight on fuel costs, capacity pressures and a lower future P/E. By comparing each of these fair values with the current US$40.21 share price you can decide which story feels closer to your own expectations and what that means for how you treat the stock.

For Southwest Airlines however, we will make it really easy for you with previews of two leading Southwest Airlines Narratives:

Fair value in this Narrative: about US$44.82 per share.

Current price vs this fair value: the shares are around 10.3% below this Narrative fair value.

Revenue growth assumption: 7.24% a year.

• Revenue is modeled to grow at a mid single digit rate, with margin improvement helped by new distribution channels like Expedia and more flexible pricing from premium, basic economy and assigned seating.
• Cost reduction efforts, shorter turn times at key airports and loyalty program changes are expected to support higher net margins and earnings over time.
• Analysts using this Narrative sit around a consensus fair value of US$44.82, with a wide range between US$24.00 and US$60.00 that reflects different views on fuel costs, customer response to new fees and long term earnings power.

Fair value in this Narrative: about US$24.03 per share.

Current price vs this fair value: the shares are around 67.4% above this Narrative fair value.

Revenue growth assumption: 6.47% a year.

• Revenue is modeled to grow but at a slower pace, with concerns that weaker business travel, higher regulatory and labor costs and the need for ongoing investment could limit margin recovery.
• Reliance on a single aircraft family and exposure to higher fuel and compliance costs are treated as key risks that could weigh on capacity plans, free cash flow and returns.
• This Narrative aligns more closely with the lower end of analyst price targets near US$24.00, where the view is that even if the business improves, the market may be pricing in too much optimism at current levels.
