What the filing shows
The report gives the holding, the date, the cost, and the stated intent to engage. A meaningful share of the position was built through an off-market block rather than slow open-market buying — a detail that reads as deliberate construction, not drift across the 5% line.
What the filing does not say: the actual proposals, the board's response, or whether IIJ is one theme among Oasis's five simultaneous positions or a standalone bet. Those are the next entries in this timeline.
