Understand Ducommun Incorporated: how it makes money

Ducommun builds engineered electronics and structural components and assemblies for aerospace and defense and other industrial markets, generating revenue by manufacturing and supplying these systems under contracts.

Profitability is tied to turning Remaining Performance Obligations into delivered contract revenue, with Military and Space representing most of the remaining backlog (0.68 USD_B of 1.1 USD_B).

Revenue by segment (latest quarter)
Elec Sys$0.1B
Struct Sys$0.1B

Business quality (Weak): The company shows backlog visibility (Remaining Performance Obligations of 1.1 USD_B) and contract momentum (Book-to-Bill Ratio of 1.1), but operating profitability is not high (operating margin 7.5%), and results appear concentrated in Military and Space.

Bull case

  • Backlog visibility: Remaining Performance Obligations are 1.1 USD_B, providing visibility into future deliveries.
  • Contract momentum: The Book-to-Bill Ratio is 1.1, indicating new orders are slightly ahead of revenue being recognized.
  • Defense and space weight in backlog: Military and Space accounts for 0.68 USD_B of the 1.1 USD_B Remaining Performance Obligations.

Bear case

  • Concentration risk: Military and Space drives a large share of backlog (0.68 USD_B out of 1.1 USD_B), which can increase sensitivity to defense program timing and budgets.
  • Modest operating profitability: Operating margin is 7.5%, which leaves less room for cost overruns or mix shifts.
  • Lower diversification in non-defense end markets: Industrial Revenue is 0.01 USD_B, so performance may rely more heavily on aerospace and defense than on industrial demand.
