Why it matters

Prime contractors and aerospace suppliers. These themes often connect to policy, commodity cycles, infrastructure spending and long investment lead times.

What to check next

Check backlog quality, project execution, input costs, balance-sheet resilience and sensitivity to commodity prices or government budgets.

Main risk

Cyclical demand, cost overruns, regulation and commodity volatility can overwhelm even a strong long-term infrastructure or energy story.
