The Metaplanet buyback pairs a share repurchase program with a $500 million credit facility to address falling mNAV and support the company’s corporate Bitcoin treasury.
Metaplanet said it will repurchase up to 150 million shares — about 13% of issued shares excluding treasury — and has secured a $500M credit facility to improve capital efficiency.
The facility is scheduled to start on Oct 29, 2025 and will run for one year; repurchases will be executed on the Tokyo Stock Exchange according to the company disclosure reported by The Block.
Since April 2024 Metaplanet has accumulated 30,823 BTC (roughly $3.5B) and reiterated a target of 210,000 BTC by end-2027.
The buyback and credit facility are aimed at limiting dilution while preserving the company’s ability to continue growing its corporate Bitcoin treasury.
Metaplanet’s market-to-net-asset value has swung sharply: a high of 10.33x on Feb 13, a low of 0.88x on Oct 17, and a recent reading of 1.03x. The stock trades around 499 JPY, well below its 1,895 JPY peak on June 16, though shares are 43.4% YTD.
Note: the effectiveness of a one-year $500M facility and large repurchase cap depends on execution, timing and market liquidity around Bitcoin and Tokyo Stock Exchange volumes.
In brief: the combined buyback and credit line is a defensive capital-management step designed to stabilise mNAV and balance short-term share supply with a long-term plan to accelerate Bitcoin accumulation.
