ARM does not actually manufacture anything -- they develop microprocessor designs which are then licensed and manufactured by others. Hence the links below refer both to ARM designs and chips manufactured by various companies.

Personal opinion (Mike Giles)
It is far from clear today whether ARM will become a real force in HPC. By the end of 2016 it should become clearer when we see whether or not 64-bit ARM server chips have achieved enough of a market share to justify further development.
Until then, this is a technology to just keep an eye on.
