Oasis Pushes Infomart Stake Past 20% and Puts a Broader Boardroom Shake-Up on the Table

Oasis Management's stake in Infomart has climbed to 20.13% from 19.00%, and the fund has already proposed asset disposals and a board reshuffle while reserving the right to push for delisting or a transaction handing an outside party majority voting control within the next year.

Oasis Management has pushed its stake in Infomart past the one-fifth mark, disclosing a holding of 20.13% in an amended large-shareholding report filed with Japan's Kanto Local Finance Bureau, up from the 19.00% shown in its previous report. The Cayman Islands-based fund now holds 53,838,600 shares of Infomart's 267,507,864 shares outstanding as of August 13, 2026, all financed with its own fund capital totaling roughly ¥29.3bn and no borrowed money. This is the fund's 13th change report on the position (previous coverage).

The filing shows Oasis has moved from dialogue to formal proposals. It says it has already asked Infomart's board to consider disposing of important company assets, appointing specific individuals as directors, making major changes to the board's composition, and discontinuing part of the business. Over the next 12 months, the fund reserves the right to go further: proposing the selection or dismissal of representative directors, mergers or share exchanges, transfers of business units, delisting Infomart's shares from the Tokyo Stock Exchange, and even an acquisition that would hand a party other than Infomart itself more than half the voting rights.

None of the forward items are commitments; the filing lists them as matters Oasis "plans to propose" within the coming year.

Oasis also disclosed plans to keep buying. It intends to raise its holding by more than five percentage points, potentially within roughly three months of the September 11 filing-obligation date, though it says the timing depends on Infomart's share price reaching a level the fund considers cheap and on other unspecified conditions. The exact price, volume, and timing remain under consideration, and any purchase requiring regulatory notification or approval could push the move beyond that window.

The transaction log attached to the filing shows the accumulation behind the jump: near-daily market purchases from July 14 through September 11, with daily volumes generally in the hundreds of thousands of shares before a single buy of 3,000,400 shares, or 1.12% of the company, on September 2. That one day accounts for a large share of the entire increase Oasis has now disclosed since its last report.

Oasis's self-imposed three-month window for the additional five-point purchase, which started on the September 11 obligation date, runs to mid-December, marking the next likely date to watch for another change report.
