Metaplanet's 131-Million-Share Cut Reveals the Real Cost of Its Bitcoin Treasury Model

Metaplanet, the Tokyo-listed company that bought its way into Bitcoin, spent September answering an uncomfortable question from its own shareholders: who actually benefits as the treasury grows? Its answer last week — cancel 131 million shares from the insiders' option pool — was framed as a concession, and it is one. But the episode lays bare the cost structure of the "Bitcoin per share" strategy more clearly than any earnings report could.

The pool in question is the Series 10 stock acquisition rights, created in February 2023 as part of a rescue of the company then known as Red Planet Japan, a hotel operator warning of insolvency. Seven staff members paid ¥18 a unit for rights to buy shares at ¥10. The initial award covered 46 million shares.

The detail that later turned this into a governance fight was a formula, not the grant itself. The pool was not fixed at 46 million shares; it was designed to always equal 20% of the company's fully diluted shares. That clause mattered once Metaplanet pivoted to Bitcoin in April 2024 and began selling stock to fund purchases — financing that pushed its share count from roughly 154 million to about 1.35 billion in two years. Every raise expanded the insiders' potential claim, and by this summer the pool had swelled to 319.5 million shares, roughly a quarter of the company.

Metaplanet itself conceded the design amplified dilution borne by existing shareholders. In mid-August the board froze the pool at that enlarged size rather than shrinking it, adding a lock-up on any sale of the resulting shares until 2031.

Then the chief executive acted in a way that turned a latent issue into a visible one. On August 28, Simon Gerovich exercised his vested share of the rights, converting 92,000 units into about 64 million shares at ¥10 each — roughly ¥640 million (about $4 million) for shares worth in the area of ¥15.6 billion ($100 million) that day. His personal stake rose to around 6%. Investors, already bothered by dilution, watched management freeze the pool one week and convert a chunk into a multibillion-yen stake the next. The stock fell by about 10% to ¥244.

Last Friday's cut was the board's retort, with Gerovich recused. It lowered the conversion ratio from 696 shares per right to 410, removing 131 million potential shares and leaving 188.2 million. After counting shares already delivered — including Gerovich's — the remaining overhang fell about 55%, to roughly 105 million. Gerovich put the value extinguished at more than $220 million, and the company scrapped a separate incentive vehicle it had been planning, saying an outside consultant would design a replacement.

The concrete payoff for a holder is the single line Gerovich used to defend the move: the cut lifts Bitcoin per fully diluted share by roughly 8.8%. That metric is the whole game for this company. Metaplanet's stated job is not to maximize treasury size or market cap; it is to compound how much Bitcoin each share represents. Because the Series 10 claim grew automatically with each equity raise, it quietly diluted that per-share number even as the headline treasury swelled. Rolling part of it back recovers real value for continuing shareholders.

What the cut does not do matters just as much. It does not unwind shares already issued on exercise, including Gerovich's 64 million, which remain outstanding and locked until 2031. Nor does it restore the pool to its pre-Bitcoin size; holders who pressed for a full reset got a 41% reduction, not a return to the original 46 million. The mechanism that amplified dilution is weakened, not abolished.

That brings the episode back to the valuation gap that made it so charged in the first place. Metaplanet's roughly 43,000 BTC are worth about $3.3 billion at current prices, while its stock has traded at a market capitalization in the neighborhood of $2 billion. A company can carry Bitcoin worth half again as much as its own equity only because investors are imposing a large discount on something — governance, financing cost, or the standing need to keep selling shares to buy more coins.

That discount is the market's read on precisely this problem. Bitcoin per share is the right scoreboard, but it is a scoreboard a company can run up by issuing equity, and every issue carries a price. Series 10 showed shareholders what that price was: an automatic claim for the people doing the buying. The 131 million shares are one installment paid to fix it. The valuation gap is the standing reminder that the market has not decided the bill is settled.
