Hasselblad had only two owners in late time, the first one Schriro Group, who acquired a majority shares of HB in 2003, Schriro also owned Imacon and merged the two companies. Before acquiring Hasselblad, the Schriro group was a major distributor for Hasselblad in the far east.
In 2011 Ventizz acquired 100% of Hasselblad.
So only two owners, but with a frequent shifting of upper management.
What is obvious is that Hasselblad is late in shipping X1D camera. That is obviously painful for the company. Hopefully the DJI investment will have a positive effect on Hasselblad.
