Metaplanet Inc., a Tokyo-listed Bitcoin treasury company often compared to Asia’s equivalent of MicroStrategy, announced a significant equity share repurchase program on October 28, 2025. The company initiated a plan to buy back up to 150 million shares—about 13.13% of its outstanding stock—backed by a Bitcoin-collateralized credit facility worth ¥75 billion (approx. $500 million).
The share buyback intends to enhance shareholder value and optimize capital efficiency amid heightened market volatility and a recent pronounced drop in Metaplanet’s market-to-net-asset value (mNAV).
Understanding mNAV and Market Impact
mNAV is a crucial metric for companies managing Bitcoin treasuries. It measures the company’s market valuation relative to the net asset value of their Bitcoin holdings. Metaplanet’s mNAV fell below 1.0 in October 2025, meaning the market now values the company at less than the worth of its Bitcoin assets.
Specifically, Metaplanet’s mNAV fluctuated sharply over the year:
- Peaked at 10.33x on February 13, 2025
- Fell to a low of 0.88x on October 17, 2025
- Stabilized near 1.03x by late October
This mNAV drop corresponds with a substantial decline in Metaplanet’s stock price from a peak of 1,895 JPY in June 2025 to around 499 JPY by late October.
Details of the Repurchase Plan
- The repurchase period runs from October 29, 2025, to October 28, 2026, operating under a discretionary trading agreement on the Tokyo Stock Exchange.
- Funding comes from a $500 million Bitcoin-backed credit line, which also serves as flexible bridge capital for preferred stock issuance and additional Bitcoin acquisitions.
- The buyback is designed to increase the Bitcoin yield per share and defend valuation when mNAV falls below 1.0x.
Effect on Bitcoin Treasury Strategy
Metaplanet holds over 30,823 BTC on its balance sheet, valued at around $3.5 billion, making it the largest corporate Bitcoin holder in Asia and the fourth-largest globally.
The buyback alongside the credit facility reflects a dual approach to:
- Limit share dilution and improve capital efficiency
- Support continued Bitcoin accumulation despite adverse market sentiment
- Boost Bitcoin yield per share, aligning with the company’s target to reach 210,000 BTC by 2027.
Market and Investor Response
The announcement triggered a roughly 10% surge in Metaplanet’s stock price to 519 JPY, with a noticeable increase in trading volume—signaling renewed investor optimism despite recent mNAV challenges.
Industry analysts view the buyback and credit facility as a defensive but strategic move to stabilize Metaplanet’s market value and maintain growth momentum in Bitcoin holdings amid turbulent market conditions.
Risk Considerations and Future Outlook
- The effectiveness of the buyback heavily depends on market liquidity and the performance of Bitcoin as collateral.
- Investors should monitor mNAV trends, stock liquidity, and Bitcoin price volatility, which will influence the company’s ability to sustain its capital strategy.
- A successful buyback, combined with ongoing Bitcoin accumulation, could potentially restore market confidence and support a stock valuation premium over Bitcoin reserves in the future.
