Tokyo-based Bitcoin treasury firm Metaplanet Inc. has announced a significant share repurchase program worth $500 million, employing a Bitcoin-collateralized credit facility to address a recent decline in its market value. This move follows an overall dip in net asset value (mNAV), which fell below 1 on the Tokyo Stock Exchange, prompting the company to take proactive measures to regain investor confidence. The program, authorized by the board, grants permission for the purchase of up to 150 million common shares, representing a 13.13% stake in Metaplanet’s total issued shares. This buyback program is set to run from October 29, 2025, through October 28, 2026, through discretionary trading on the Tokyo Stock Exchange. ]
