The exact mention is that Ash was "
an older model (...) Hyperdyne Systems".
Back then, it was a kind of easter egg by James. But if we are taking Bishop and Burke's lines seriously, as a fundamental worldbuilding element...
Well, with this phrasing, Hyperdyne Systems could be anything: a specific line of synthetics, a building norm, a secondary subcontractor, a specific division, a sub-company, anything.
It does not contradict the domination of these "five big".
If anything, Alien: Romulus seems to indicate that both N–D–255 and 120-A/2 models (... what is this nomenclature even) are entirely affiliated with Weyland-Yutani. "
He's a Weyland-Yutani synthetic. He speaks Mother". So my money would be on Hyperdyne being a subdivision/subcompany of Weyland-Yutani. About as autonomous as Aspen Beer.
