Metaplanet, Japan’s largest publicly traded Bitcoin treasury company, is considering a share repurchase program after its market-to-net asset value (mNAV) ratio fell below 1.0x, signaling the stock trades at a discount to the value of its Bitcoin holdings.
The company’s mNAV ratio hit 0.90 in the past 24 hours, crossing the threshold that activates Metaplanet’s capital allocation policy. Simon Gerovich, CEO and Representative Director, said on X: “When mNAV is below 1.0x we will strongly consider repurchasing common shares to maximize BTC Yield, and the lower the mNAV, the greater the potential accretion.”
Metaplanet holds 40,177 BTC with an approximate acquisition cost of $4.18 billion, or $104,106 per coin on average. At a 0.90x mNAV ratio, buying back shares at current market prices is mathematically equivalent to acquiring Bitcoin at a discount to spot price. Each share retired increases the Bitcoin per share ratio for remaining shareholders without requiring new coin purchases.
The stock closed 2.95% higher at 244 yen on June 9 following Gerovich’s announcement. The move comes after Metaplanet’s stock declined 47% year-to-date and 30% over the past month, pressuring the company’s primary performance metric: BTC Yield, which measures Bitcoin held per diluted share. Metaplanet reported a 2.8% BTC Yield for Q1 2026.
Metaplanet ranks third-largest publicly traded corporate Bitcoin holder globally, behind Strategy and Twenty One Capital. The company’s “555 Million Plan” targets 100,000 BTC by year-end and 210,000 BTC by 2027, requiring approximately $10 billion in additional capital at current prices.
How share buybacks work at mNAV discount
When a Bitcoin treasury company’s market cap trades below its net asset value, repurchasing shares becomes a tool to improve per-share metrics without diluting existing holders. Metaplanet’s policy formalizes this approach, tying buyback consideration directly to the mNAV ratio.
The lower the mNAV, the greater the accretion per share retired. At 0.90x, each buyback dollar acquires approximately $1.11 in Bitcoin value on a per-share basis. This mechanism protects shareholders from dilution while the stock remains discounted.
Gerovich did not specify whether Metaplanet will execute buybacks immediately or provide a timeline for execution. The company also did not disclose available liquidity for repurchases. Metaplanet’s ability to fund buybacks while pursuing its 2027 target of 210,000 BTC will depend on capital availability and market conditions.
Context: Bitcoin treasury company valuations under pressure
Metaplanet’s mNAV discount reflects broader pressure on publicly traded Bitcoin treasury companies. Strategy and Twenty One Capital, which hold larger Bitcoin positions, have faced similar valuation dynamics as institutional demand for corporate Bitcoin exposure competes with direct spot purchases and Bitcoin ETFs.
BTC Yield remains Metaplanet’s key performance indicator. The 2.8% reported for Q1 2026 measures the growth in Bitcoin held per diluted share, accounting for both new acquisitions and share dilution from equity issuance or employee compensation.
