Way back when Arm were dual listed one of the explanations was that US based customers (meaning US based semi companies) preferred that the company was listed in the US and subjected to a similar regime, in addition to needed capital. To be honest, that actually makes a decent amount of sense, but I suspect the real reason was to enable US investors to buy into it so they do not then support attacking the foreign interloper in their industry.
