Core Financial Metrics: BTC Yield, BTC Gain & BTC円Gain
To measure the effectiveness of its Bitcoin investment strategy, Metaplanet employs three proprietary KPIs: BTC Yield, BTC Gain, and BTC円Gain. These metrics help quantify shareholder value creation independent of stock dilution.
What Is BTC Yield?
BTC Yield measures the quarter-over-quarter percentage change in the ratio of total Bitcoin holdings to fully diluted shares outstanding. It reflects how efficiently the company grows its BTC reserves relative to potential equity dilution.
Recent quarterly BTC Yield figures:
- Q3 FY2024 (Jul–Sep 2024): +41.7%
- Q4 FY2024 (Oct–Dec 2024): +309.8%
- Q1 FY2025 (Jan–Mar 2025): +95.6%
- Q2 FY2025 (Apr–Jun 26, 2025): +112.2%
These figures indicate accelerating efficiency in growing Bitcoin value per fully diluted share.
Understanding BTC Gain and BTC円Gain
- BTC Gain: Represents the net increase in Bitcoin holdings attributable solely to financial strategy (excluding new share issuance). Calculated by multiplying initial BTC holdings by BTC Yield.
- BTC円Gain: Converts BTC Gain into Japanese yen using the Bitcoin market price on the last day of the reporting period.
Quarterly BTC円Gain results:
- Q3 FY2024: ¥892 million
- Q4 FY2024: ¥18.7 billion
- Q1 FY2025: ¥25.5 billion
- Q2 FY2025: ¥71.2 billion
The sharp rise in Q2 highlights both strong BTC price performance and effective capital deployment.
Note: The BTC/JPY reference price used across all periods is ¥15,689,243 (Bitflyer closing rate), ensuring consistency in comparisons.
Capital Markets Strategy: Funding Bitcoin Purchases
Metaplanet has leveraged structured financing tools to fund its Bitcoin acquisitions without relying solely on traditional equity or debt markets.
The “21 Million Share Plan”
In January 2025, the board approved the issuance of up to 210 million new share warrants (Tranches 13–17) to EVO FUND at zero discount. These warrants were designed to provide flexible funding for Bitcoin purchases while allowing for early repayment via bond issuance.
Key milestones:
- All tranches fully exercised by May 20, 2025
- Total proceeds: ~¥35.998 billion
- Enabled rapid scaling of BTC reserves from under 4,000 to over 12,000 BTC within six months
Zero-Coupon Bond Issuances
To accelerate purchases, Metaplanet issued multiple short-term zero-coupon bonds to EVO FUND:
| Bond Issue | Amount Raised | Maturity Date | Repaid? |
|---|---|---|---|
| 6th Ordinary Bond | ¥4 billion | Aug 12, 2025 | Yes (Feb 19–21) |
| 7th | ¥2 billion | Aug 26 | Yes (Mar 3) |
| 8th | ¥2 billion | Sep 11 | Yes (Mar 26) |
| 9th | ¥2 billion | Sep 17 | Yes (Apr 4) |
| 10th | ¥2 billion | Sep 30 | Yes (May 1) |
| 11th | $10M USD | Oct 14 | Yes (May 1) |
| ... up to 18th | $210M USD | Dec 12 | Yes (Jun 25) |
All bonds were prepaid early using warrant exercise proceeds, demonstrating a self-sustaining capital loop.

Fully Diluted Share Count and Anti-Dilution Safeguards
A critical aspect of Metaplanet’s strategy is minimizing shareholder dilution while expanding the treasury.
As of June 26, 2025:
- Outstanding shares: 654,714,340
- Fully diluted shares: 826,567,925
- BTC per 1,000 fully diluted shares: 14.935
The company uses U.S.-aligned accounting standards for measuring dilution:
- Includes stock options, convertible bonds, and exercisable rights
- Zero-discount warrants only counted upon exercise and settlement
- Ensures accurate reflection of true equity impact
A reverse stock split (10:1) was implemented on April 1, 2025, adjusting historical data accordingly.
Frequently Asked Questions (FAQ)
Q: What is BTC Yield and why does it matter?
A: BTC Yield measures how much a company’s Bitcoin holdings grow relative to its fully diluted share count. A rising BTC Yield indicates that shareholders are gaining more exposure to Bitcoin even if shares are issued.
Q: How does Metaplanet afford large Bitcoin purchases?
A: Through a combination of operating income, warrant issuances at fair market value, and short-term zero-coupon debt. Proceeds are recycled quickly to repay debt, creating a low-cost acquisition engine.
Q: Are these KPIs GAAP-compliant financial metrics?
A: No. BTC Yield, BTC Gain, and BTC円Gain are non-GAAP indicators created specifically for investor transparency around Bitcoin strategy. They should be used alongside audited financial statements.
Q: Does holding Bitcoin replace dividends for shareholders?
A: Currently, Metaplanet does not pay dividends. Instead, it reinvests capital into Bitcoin to increase long-term shareholder value. Ownership of Metaplanet stock does not equate to direct ownership of Bitcoin.
Q: Could this strategy fail if Bitcoin price drops?
A: While short-term volatility affects market valuation, Metaplanet focuses on long-term accumulation at decreasing average costs. The strategy assumes Bitcoin will appreciate over time as global adoption grows.
Q: Is Metaplanet similar to MicroStrategy or Tesla?
A: Like MicroStrategy, Metaplanet treats Bitcoin as a primary treasury asset. However, its use of warrant-financed bond structures represents a more dynamic capital markets approach tailored to Japanese regulatory and market conditions.
