Collins Earns 6.9% on Its Segment AssetsThin moat

RTX (RTX) — moat facet

Collins earns a 16% margin on sales but only about 7% before tax on the $72 billion of assets, half of it goodwill, that its owners paid for.

Collins's margin on sales looks healthy; its return on the assets behind it does not. The segment's operating profit was $4,923 million in 20251. Its segment assets were $71,680 million2. That is a pre-tax return of about 6.9%3.

Every segment under 8% before tax.

The difference is goodwill. Collins was assembled by acquisition, most recently Rockwell Collins, bought in November 20184, and the segment carries $32,776 million of goodwill5, nearly half its assets. The shareholders who bought those businesses paid for their future profits in advance, so the profits now have to cover the purchase price as well as the factories.

Raytheon earns 7.2% on its $44,795 million of segment assets and Pratt & Whitney about 4.9% on $52,482 million67. Collins is not the weak segment; the whole company carries the same weight.

This is why the moat and the return diverge. Collins's position on aircraft is durable, and its parts are hard to displace once certified. But a durable position bought at a high price earns an ordinary return.

The segment's assets are larger than any other's. Collins held $71,680 million of segment assets at the end of 2025, against $52,482 million at Pratt & Whitney and $44,795 million at Raytheon8. Its return lags its margin because of that base, not because of weak operations.

Collins is shedding assets as well as adding profit. It sold Simmonds Precision Products for about $0.8 billion in October 2025 with a pre-tax gain of about $0.1 billion9, and the actuation business the same year. Each sale shrinks the asset base and lifts the ratio slightly, alongside the operating improvement.

The number moves as profit grows faster than assets. At 6.9% before tax, Collins does not yet earn an 8% cost of capital after tax; each year its operating profit grows while its asset base holds near $72 billion brings that closer. A new large acquisition would reset it.

Whether the price paid for Collins is being earned; a rise toward 10% would mean the goodwill is being covered.

How it's calculated: Collins operating profit ($4,923M) divided by Collins segment assets ($71,680M) at 31 December 2025, from Note 20 of the FY2025 10-K; pre-tax.
