Is Boeing’s Recent 18% Rally Justified by Its Cash Flow and Sales Valuation?

Simply Wall St
  • If you have ever wondered whether Boeing is finally trading at a price that actually makes sense after years of turbulence, you are not alone. This article is here to unpack exactly that.
  • After climbing 8.4% over the last week and 17.8% year to date, Boeing shares sit around $202.54, even though the 5 year return is still down 12.7%. This hints that the market might be rethinking the company’s future.
  • Much of this shift in sentiment ties back to ongoing progress in resolving safety and regulatory issues, alongside renewed optimism around long term demand for commercial aircraft as airlines refresh fleets and global travel continues to recover. At the same time, Boeing’s defense and space contracts have kept it central to US and allied government spending plans and this provides a strategic backdrop to the stock’s recent moves.
  • Right now, Boeing earns a valuation score of 6/6 on our checklist of under or overvaluation signals. Next, we will walk through the key valuation approaches behind that score before exploring an additional way to think about what the stock is really worth.

Boeing delivered 28.0% returns over the last year. See how this stacks up to the rest of the Aerospace & Defense industry.

Approach 1: Boeing Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model projects a company’s future cash flows and then discounts them back into today’s dollars, aiming to estimate what the whole business is worth right now. For Boeing, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections.

Today, Boeing is still burning cash, with last twelve month free cash flow around $5.9 Billion in the red. Analysts expect this to swing strongly positive over the next few years, with projected free cash flow climbing into the low tens of Billions. By 2029, Simply Wall St’s model, which extends analyst forecasts out to 10 years, estimates free cash flow of about $11.6 Billion, with later years continuing to grow but at a slowing pace.

When all those projected cash flows are discounted back, the intrinsic value comes out at roughly $300.39 per share, compared with the current share price near $202. This implies Boeing is about 32.6% undervalued based on cash flow potential.

Result: UNDERVALUED

Approach 2: Boeing Price vs Sales

For companies like Boeing that are still rebuilding profitability, the price to sales ratio is a useful way to value the business because it focuses on revenue, which tends to be more stable than earnings during a turnaround. Investors usually expect higher growth and lower risk to justify a higher multiple, while slower growth or greater uncertainty tends to pull a normal or fair price to sales ratio down.

Boeing currently trades on a price to sales ratio of 1.91x, which is slightly below both the Aerospace and Defense industry average of 3.02x and the peer average of 1.93x. Simply Wall St also calculates a Fair Ratio of 2.07x for Boeing, which is the multiple the company might reasonably trade at given its growth outlook, margins, industry positioning, market cap and risk profile.

This Fair Ratio is more informative than simple peer or industry comparisons because it adjusts for Boeing’s specific fundamentals rather than assuming all companies deserve the same multiple. With the current 1.91x price to sales ratio sitting below the 2.07x Fair Ratio, Boeing appears modestly undervalued on this measure.

Upgrade Your Decision Making: Choose your Boeing Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, a simple way to connect your view of Boeing’s story with concrete numbers like future revenue, earnings, margins and a fair value estimate. A Narrative on Simply Wall St’s Community page is your own storyline for the company, translated into a financial forecast and then into a Fair Value that you can compare to the current share price to inform your decision to buy, hold or sell. Because Narratives are updated dynamically as new news, earnings and guidance arrive, they stay relevant rather than going stale. For Boeing, one investor might build a bullish Narrative around accelerating 737 MAX production, expanding defense contracts and mid teens revenue growth that supports a Fair Value closer to the higher analyst targets. Another might focus on execution risks, debt and thinner margins that justify a Fair Value nearer the lowest estimates. Seeing those different Narratives side by side helps you decide which story, and which price, you actually find more compelling.
