Approach 1: Ducommun Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes estimates of the cash a business could generate in the future and discounts those amounts back to what they might be worth in today's dollars.

For Ducommun, the latest twelve month free cash flow is a loss of about $50.4 million. The model then looks ahead to projected free cash flows, using analyst estimates where available and extending them further out. For example, free cash flow for 2028 is projected at $108.6 million, and the model includes a path of annual figures through to 2035 based on a two stage Free Cash Flow to Equity approach.

Putting all of those projected cash flows together and discounting them back, Simply Wall St arrives at an estimated intrinsic value of about $206.51 per share for Ducommun. Against the recent share price of $140.59, this implies the stock trades at a 31.9% discount to that DCF estimate, which points to Ducommun being undervalued on this specific cash flow model.

Result: UNDERVALUED

Approach 2: Ducommun Price vs Sales

Price to Sales, or P/S, is often a useful way to look at valuation when you want to compare how much investors are paying for each dollar of revenue, especially for companies where earnings can be volatile.

In general, higher growth expectations and lower perceived risk can support a higher P/S multiple. In contrast, slower growth or higher risk usually point to a lower figure being more reasonable. The question is therefore not just whether a multiple is high or low in isolation, but whether it lines up with the company’s profile.

Ducommun currently trades on a P/S ratio of 2.55x. This sits below the Aerospace & Defense industry average P/S of 5.15x and below the peer group average of 4.64x. Simply Wall St also calculates a proprietary “Fair Ratio” for the preferred multiple, which for Ducommun is 1.18x. This Fair Ratio is designed to be more tailored than a simple peer or industry comparison because it factors in elements such as earnings growth, profit margins, the company’s industry, market cap and specific risk profile.

Comparing Ducommun’s actual P/S of 2.55x to the Fair Ratio of 1.18x suggests the shares trade above that custom estimate.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Ducommun Narrative

Earlier the article mentioned that there is an even better way to think about valuation. On Simply Wall St that starts with Narratives, where you turn your view of Ducommun into a simple story that links assumptions about future revenue, earnings and margins to a financial forecast, a Fair Value, and then a clear comparison with the current price. All of this is contained within an easy tool on the Community page that updates automatically when new news or earnings arrive. This allows you to quickly see whether your story still holds up. For example, one Ducommun Narrative might lean on the analyst fair value of US$143.60 with expectations for revenue of US$1.0b, earnings of US$90.8m and a P/E of 30.5x in 2029. Another more cautious Narrative might assume lower revenue, thinner margins and therefore a lower Fair Value, showing how two investors can look at the same company and reach very different conclusions using the same shared framework.
