What changed
Oasis Management has crossed the 5% line at Infomart and turned the disclosure into a statement of intent. The fund reported a 5.07% holding, or 13,568,100 shares, said the reporting threshold arose on June 25, and listed ¥5.49bn of acquisition funding.
What Oasis says it wants
The ownership threshold is only half the story. In the filing's purpose statement, Oasis says it wants constructive dialogue with management to improve Infomart's long-term corporate value and governance. It also says it has already made proposals on disposing of material assets and abolishing all or part of a business.
Over the next 12 months, Oasis says it may also make proposals on the appointment or dismissal of representative directors and executive officers, broader changes to board composition, mergers, share exchanges, company splits, business transfers, suspensions or discontinuations, delisting, and transactions that would leave a third party holding more than half of the voting rights. The filing does not say every one of those steps will be pursued, but it does reserve a notably wide legal menu.
How fast it may add
Oasis also says it plans to increase its holding ratio further above 5% through market or off-market trades, if Infomart's share price is at a level it regards as undervalued and other conditions are met. Its current plan is to do that within three months of June 25, although the filing says the timing could slip and some purchases may require notification to, or approval from, authorities.
The recent 60-day acquisition table shows two on-market purchases, on June 24 and June 25, and no unit prices were listed.
| Date | Shares acquired | Stake ratio | Venue | Action |
|---|---|---|---|---|
| 2026-06-24 | 295,500 | 0.11% | On-market | Acquisition |
| 2026-06-25 | 689,700 | 0.26% | On-market | Acquisition |
Why it matters
For readers outside Japan, the message is that this is not a bare threshold notice. Oasis has already disclosed proposals on asset disposals and business shutdowns, and it has left itself room to press for governance changes, restructuring and potentially control-related outcomes while building a larger stake. What the filing does not provide is Infomart's response, any agreed timetable, or specific terms for any future proposal.
