Metaplanet (3350): What the Japanese Retail Boards Argue About — and How to Check Each Claim

Discussion of Metaplanet (TSE Standard, 3350) looks scattered but converges on a few recurring arguments: how much Bitcoin the company holds, mNAV, dilution from warrants, and the link to a weak yen.

This page sets out what each argument is actually asking and which company disclosure answers it. It does not decide who is right, and it quotes or summarises no individual post. What it covers is the shape of the arguments and the primary documents that bear on them.

What Metaplanet's Bitcoin treasury model is

Metaplanet's board resolved on 8 April 2024 to adopt Bitcoin as the primary component of its treasury assets, and Bitcoin Treasury Operations became a formal business line on 18 December 2024. Since then the company has funded purchases through common and preferred equity issuance, ordinary bonds, and a Bitcoin-collateralised credit facility.

The most recent holdings figure the company has disclosed is 43,000 BTC as of 30 June 2026. At that date the aggregate cost basis was JPY 659.256 billion and the average purchase price JPY 15,331,542 per Bitcoin; the quarter's purchases were 2,823 BTC at an average of JPY 12,712,055 (Notice of Additional Purchase of Bitcoin, 2 July 2026).

Holdings are updated on a quarterly cycle. The figure above may already be stale by the time you read this — check the company's IR disclosures for the current number.

Debate 1: mNAV — what the ratio measures

The most common argument is whether the share price is expensive or cheap relative to the Bitcoin held. The yardstick people reach for is mNAV.

The first thing worth knowing is that mNAV is not an outsider's coinage. It is defined and used by the company itself: "the ratio calculated by dividing enterprise value by the net asset value of BTC holdings at market price" (Notice Regarding Revision of Capital Allocation Policy, 16 March 2026). At 1.0x, the equity market is valuing the company at roughly what its Bitcoin is worth.

Why the number is contested. Partly the numerator: market capitalisation alone gives a different answer from a full enterprise value including debt and preferred equity — same company, same day. The 30 June 2026 disclosure lists roughly JPY 8.0 billion of non-interest-bearing yen ordinary bonds, JPY 67.2 billion of foreign-currency-denominated debt, and MERCURY convertible preferred stock with a JPY 23.61 billion notional; how you treat those is a judgement call. Partly the denominator: the Bitcoin price moves intraday, so the reference moment matters.

The reading of "below 1.0x" splits too. One reading is that you are buying assets for less than they are worth; the other is that the market is assigning the operating business a value of zero or less. This page takes neither position.

But one fact is worth holding onto. For Metaplanet, 1.0x is not only a subject of commentary — it is a written capital-policy threshold. The same revised policy states that, as a matter of principle, the company will not raise equity through common-stock issuance below 1.0x; that below 1.0x it will execute share buybacks to maximise BTC Yield; and that buybacks may also occur above 1.0x where management judges the share price to significantly undervalue intrinsic enterprise value. One of its three stated strategic objectives is "enhancement of mNAV".

So an argument about whether the ratio is under 1.0x is simultaneously about valuation and about which capital action the company's own policy points to next. Note that the company publishes no running mNAV figure: its most recent statement on the level — "approximately 1.0x" — is frozen in the 16 March 2026 disclosure.

Debate 2: dilution — warrants and Bitcoin per share

Here the disagreement is less about facts than about the same word covering two different sets of shares.

The actual share count. Issued common shares went from 654,714,340 (30 June 2025) to 1,140,974,340 (30 September 2025), 1,142,274,340 (31 December 2025), 1,274,171,340 (31 March 2026) and 1,281,283,624 (30 June 2026). At 31 July 2026 the figure was 1,281,308,624, including 26,843 treasury shares.

The unexercised warrants. At 31 July 2026 the 27th Series stood at 947,300 rights (94,730,000 shares), the 25th Series at 15,944,000 shares and the 26th Series at 107,368,000 shares, all unexercised — 218,042,000 shares if you simply add them. Separately, the 23rd and 24th Series account for a combined 210,000,000 shares and are suspended from exercise; the company has said it will reassess resumption after the 27th Series completes.

This is the fork. The Effective Diluted Shares Outstanding used in the company's BTC Yield calculation includes issued common shares, potential shares from convertibles whose proceeds have already been delivered, and outstanding stock options — but excludes the 25th, 26th and 27th Series rights and existing moving strike warrants until they are exercised and the proceeds received. The company's stated reason is that reflecting dilution before the capital arrives would misrepresent the economics. On that basis, Effective Diluted Shares Outstanding at 30 June 2026 was 1,631,543,380.

A reader using the company's diluted count and a reader adding every unexercised right are both working from disclosed numbers and seeing different pictures. Much of the dilution argument is that definitional gap.

What the company's KPI shows. BTC Yield is the percentage change in the ratio of total Bitcoin holdings to Effective Diluted Shares Outstanding — in the company's Japanese phrasing, the growth rate of Bitcoin held per share. Bitcoin per Effective Diluted Share (disclosed per 1,000 shares) moved 0.0240486 at 31 December 2025, 0.0247319 at 31 March 2026, 0.0263554 at 30 June 2026. Quarterly BTC Yield ran 129.4% in Q2 2025, then 33.0%, 11.9%, 2.8%, and 6.6% in Q2 2026.

Both sides follow. One argument: the share count grew, but Bitcoin per share grew too, so existing holders came out ahead on the company's own measure. The other: include the unexercised overhang and the picture changes, and quarterly BTC Yield has fallen sharply besides. The first reads the KPI as defined; the second looks outside the definition. Neither is inventing data.

The company is explicit about the limits. These KPIs "are not measures of operational performance, financial performance, or liquidity"; they exclude "debt obligations, preferred stock, or other senior claims on company assets"; "these KPIs do not predict or determine our stock price"; and "holding our common shares does not equate to direct ownership of the Bitcoin we hold."

The buyback authorisation is part of this. A resolution of 28 October 2025 authorised repurchases of up to 150,000,000 shares (13.13% of issued shares excluding treasury) and up to JPY 75 billion, running to 28 October 2026. As of 31 July 2026, purchases under it totalled 0 shares and JPY 0 — an authorisation existing and an authorisation being used are separate facts, and the monthly disclosure separates them.

Dilution and the 27th Series design are connected. The exercise price is revised each trading day to the previous day's close — or the floor exercise price if that close falls below it — at, in the company's words, a 0% discount, and under the mNAV clause the holder may only exercise when mNAV is 1.01x or higher (details in the FAQ). So the pace of exercise tracks the share price: in Q2 2026, 5,270,000 shares were issued through 27th Series exercises during periods when the 1.01x condition was met, while July 2026 exercises were zero.

Debate 3: the yen-weakness argument

What the company says. In the 8 April 2024 notice announcing its first Bitcoin purchase, Metaplanet wrote that "the depreciation of the Japanese yen over the past several years and Japan's generation-long perpetual low interest rate environment has damaged the Japanese yen's position as a key global currency", and said it intended a treasury position "which minimizes Japanese yen exposure". The same notice lists "Inflation and Currency Hedge" first among its rationales. The yen framing is not an outside interpretation — it is the company's founding explanation of itself.

From there, separate the mechanical from the interpretive. Mechanically, a yen-denominated Bitcoin price is the dollar price multiplied by USD/JPY. Every figure the company discloses — cost basis, average purchase price, reference price — is in yen; its BTC/JPY reference is bitFlyer's daily close, and it benchmarks effective net acquisition cost against bitFlyer's quarterly BTC/JPY VWAP. A yen-quoted position can change in value on the exchange rate alone. That is definitional, not a forecast.

Interpretive is attributing share-price moves to any one driver. The dollar Bitcoin price, USD/JPY, equity supply and demand, and the warrant exercise dynamics above all move at once, and no disclosure decomposes them. That is usually why "it rose on the weak yen" and "the yen has nothing to do with it" fail to meet.

FX does not only touch the asset side. At 30 June 2026 the company carried approximately JPY 67.2 billion of foreign-currency-denominated debt. Currency moves run through both sides of the balance sheet, and an argument about the yen that looks at only one side is incomplete.

How to check each claim yourself

Checkable claims map almost without exception onto one of four documents.

1. Holdings, cost basis, BTC Yield, diluted share count. The quarterly Notice of Additional Purchase of Bitcoin — all of it in one file, together with the metric definitions and the company's own statement of their limitations.

2. Share count and unexercised warrants. The monthly Notice Regarding Monthly Exercise Status of the 27th Series of Stock Acquisition Rights: exercises in the month, unexercised rights at month-end, total issued common shares, and the 25th and 26th Series for reference.

3. Buyback execution. The monthly Notice Regarding the Status of Share Repurchases: shares and yen acquired, plus the cumulative total under the authorising resolution.

4. The mNAV framework. The Notice Regarding Revision of Capital Allocation Policy of 16 March 2026: the mNAV definition, the 1.0x thresholds governing issuance and buybacks, the guideline of keeping borrowings below roughly 10% of Bitcoin NAV, and the three strategic objectives.

All are reachable from the disclosure index — https://metaplanet.jp/en/disclosures, or https://metaplanet.jp/ja/disclosures in Japanese. A tracker also exists at analytics.metaplanet.jp, but for anything you intend to cite, the timely-disclosure PDF is the safer source.

FAQ

How much Bitcoin does Metaplanet hold now? The most recent disclosed figure is 43,000 BTC as of 30 June 2026 (disclosed 2 July 2026). Holdings are updated quarterly, so check the company's IR disclosures for the current number.

Where can I see the current mNAV? The company defines mNAV as enterprise value divided by the market-value net assets of its Bitcoin holdings, but does not publish a running figure. Any number you see elsewhere was calculated by someone under assumptions of their own. Before comparing two figures, check what each puts in the numerator and at what moment it prices the Bitcoin — different assumptions producing different numbers is not a contradiction.

What are the "MS warrants" people mention? Shorthand for stock acquisition rights whose exercise price is periodically revised; the company itself calls the 27th Series "MS Warrants" in its English disclosures. The formal name is the 27th Series of Stock Acquisition Rights with Exercise Price Adjustment, mNAV, Floor Price Adjustment and Exercise Suspension Clauses — resolved 16 March 2026, issued 1 April 2026, allotted to EVO FUND, 1,000,000 units representing 100,000,000 potential shares. The suspension clause is live: the 23rd and 24th Series were suspended effective 24 March 2026.

Does a high BTC Yield mean shareholders are better off? Not straightforwardly, on the company's own account. It states that the metric is not a measure of operational or financial performance or liquidity, that it excludes debt, preferred stock and other senior claims, and that it does not predict or determine the share price. Read it alongside the questions it is not designed to answer.
