Koninklijke Philips N.V holds over 10% of float -bought 7.4Mshares at the end of July 2017.
We probably know them best for consumer electronics, shavers, lighting, etc. The are big into healthcare now.
I expect that they knew what they were doing when they acquired 7.4 million shares at $1.10 per share on July 31, 2017. Maybe they'll be acquiring more?
