Do we know whatever happened to Roche's then 5% stake in HALO, which it acquired at the time of the original deal in 2006?
"The Roche Venture Fund will make an $11 million equity investment, representing approximately 5% of Halozyme’s outstanding common stock."
Fezz is ranting on that it's only a matter of time before Roche bids for HALO. If this is true you would have thought that Roche would have been adding to their stake.
