Sell side and buy side. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it. Answers lead with the point, then the mechanism, then the limitation.

076How would you analyse an industrial or capital goods company?William BlairInvestment Banking · Atlanta · 2026
Say this
Order book first. Orders lead revenue by quarters or years, so the book-to-bill ratio and backlog are the leading indicators. Then margin through the cycle, then the aftermarket.
Then walk it
- Orders and backlog: book-to-bill above one means the backlog is growing and revenue will follow. This is the single most useful disclosure in the sector and the source of most variant views.
- Backlog quality matters as much as size: execution timeline, cancellation risk, and whether contracts are fixed price or cost plus. Fixed-price contracts in an inflationary period are where margins get destroyed.
- Margin: high operating leverage from a fixed manufacturing base, so incremental volume drops through heavily. Model incremental margins rather than absolute margins.
- The aftermarket is the quality of the business. Spare parts and service carry much higher margins than original equipment and are far less cyclical, so the installed base is an annuity. Companies with a high service mix deserve a materially higher multiple.
- Working capital and cash conversion: long production cycles tie up cash, and advance payments from customers can fund it. Watch the gap between reported profit and cash.
- And position it in the cycle: capital goods demand follows capacity utilisation and credit conditions in the customer industries, so the analysis is really about the customers' capital expenditure plans.
Where candidates lose it
Ignoring the aftermarket. The recurring service revenue is usually the majority of the profit and the entire reason some industrials trade at premium multiples. Missing it means missing the investment case.
