The pitch deck is a fiction. The code is the reality. In this case, the "code" is a warrant structure that could silently strip 24.1% of shareholder Bitcoin exposure.
On August 31, 2025, Capital B—a European Bitcoin Treasury Company—will close a €21 million private placement. The headline is simple: 36,219,070 new shares at €0.58 per unit, each bundled with four warrants. The proceeds will purchase approximately 270 Bitcoin, lifting the corporate treasury from 3,145 BTC to 3,415 BTC.
The narrative is seductive. Another MicroStrategy disciple accumulating the world's hardest asset. Another vehicle for institutional Bitcoin exposure through traditional equity markets.
Read the code, not the pitch deck. The code here is financial engineering, and it reveals something far less flattering: a dilution mechanism that could reduce per-share Bitcoin holdings by nearly a quarter, with additional dilution tools deliberately excluded from the company's own disclosure.
This is not a story about Bitcoin. It is a story about how financial complexity hides the body.
The Context: A Crowded Field of Bitcoin Mimics
MicroStrategy pioneered the Bitcoin Treasury Company model between 2020 and 2024, amassing approximately 226,500 BTC and achieving a market valuation exceeding $30 billion at its peak. The playbook is straightforward: raise capital through equity or debt instruments, convert proceeds into Bitcoin, and position the company as a leveraged Bitcoin proxy for equity investors.
The model's success spawned imitators. Metaplanet in Tokyo, Boyaa Interactive in Asia, and now Capital B in Europe. Each follows the same template with local variations. Each claims to offer shareholders something unique.
Capital B's differentiation is its warrant structure. Unlike MicroStrategy's convertible notes—which do not dilute existing shareholders until conversion—Capital B's warrants constitute contingent dilution from the moment of issuance. Four warrants per share, with strike prices at €0.75, €0.98, and €1.27, exercisable over five years.
The company's existing treasury of 3,145 BTC places it firmly in the small-cap category of Bitcoin Treasury Companies. At approximately $80,000–$90,000 per Bitcoin, the treasury is valued between $250 million and $280 million. The new raise adds roughly $23 million in purchasing power.
The immediate transaction is nearly neutral for existing shareholders. The company's own disclosure confirms this: per-million-share Bitcoin holdings shift from 7.4725 BTC to 7.4711 BTC—a negligible 0.02% decline. The company can claim, with technical accuracy, that this raise does not meaningfully dilute shareholder Bitcoin exposure.
But the warrants tell a different story.
The Core: Dissecting the Dilution Mechanics
Let me walk through the mathematics, because the numbers matter more than the narrative.
Current state: 3,145 BTC held by the company. The company's disclosure indicates approximately 7.4725 BTC per million shares outstanding. This implies roughly 420.8 million shares currently issued.
Post-placement: 36,219,070 new shares are issued at €0.58 per unit. Total shares rise to approximately 457 million. The treasury increases to 3,415 BTC. Per-million-share BTC: 7.4711. A 0.02% decline. Essentially flat.
Post-warrant exercise: Each new share carries four warrants. Total warrants issued: 144,876,280. If all warrants are exercised at their respective strike prices, the company issues an additional 144.9 million shares. Total share count rises to approximately 601.9 million.
The math is brutal. 3,415 BTC divided by 601.9 million shares, multiplied by one million, equals 5.6730 BTC per million shares. That is a 24.1% decline from the current 7.4725 BTC per million shares.
Let me be precise about what this means. A shareholder holding 1% of the company today owns 1% of 3,145 BTC—approximately 31.45 BTC. After the placement, their stake falls to 0.9% of 3,415 BTC—approximately 30.74 BTC. After full warrant exercise, their stake falls to approximately 0.65% of 3,415 BTC—approximately 22.2 BTC.
A 29.4% reduction in Bitcoin exposure from current levels, assuming all warrants are exercised and the proceeds are used to purchase additional Bitcoin.
But here is the critical question: will the warrant exercise proceeds actually be deployed into Bitcoin? The company has not committed to this. The disclosure states the €21 million will purchase approximately 270 BTC. The warrant proceeds—potentially exceeding €100 million if fully exercised—have no such commitment.
This is the structural flaw. The company's stated goal of "increasing diluted Bitcoin holdings per share" is achieved only at the immediate placement level. The warrant structure creates a 24.1% overhang that the company has not addressed with a corresponding Bitcoin purchase commitment.
The Hidden Dilution: What the Company Didn't Disclose
The company's dilution calculation excludes several instruments. This is where complexity hides the body.
First, the older BSA series warrants. The company references "older BSA series warrants" without disclosing their terms, quantity, or strike prices. These constitute additional contingent dilution that is not included in the 24.1% figure.
Second, convertible bonds with attached warrants. The company has previously issued convertible debt with warrant attachments. The conversion terms and warrant coverage are undisclosed.
Third, the TOBAM facility. A €300 million undrawn facility with TOBAM, a French asset management firm, remains available. The terms of this facility—including any equity conversion or warrant components—are not disclosed.
Fourth, the shareholder authorization. In June 2025, shareholders authorized a €5 billion capital increase and a €100 billion credit instrument facility. These authorizations are not commitments, but they signal management's intent to pursue aggressive capital raising. Every future raise will carry similar warrant structures.
The disclosed 24.1% dilution is a floor, not a ceiling. The actual dilution risk is materially higher.
The Market Reality: A Small Player in a Winner-Take-All Game
Capital B's 3,145 BTC represents approximately 1.4% of MicroStrategy's holdings. The company is a marginal player in a sector where scale matters for institutional adoption.
MicroStrategy's convertible note structure is superior to Capital B's warrant structure. Convertible notes do not dilute existing shareholders until conversion, and conversion typically occurs at a premium to the current share price. Warrants, by contrast, constitute contingent dilution from issuance, and their strike prices (€0.75–€1.27) represent a 29%–119% premium to the current placement price of €0.58.
The warrant strike prices reveal management's expectations. They anticipate significant share price appreciation. If the share price does not reach these levels, the warrants expire worthless, and the company loses the associated capital. If the share price does reach these levels, the company faces 24.1% dilution without a committed Bitcoin purchase program.
This is a heads-I-win, tails-you-lose structure for management. In a bull case, the company raises additional capital through warrant exercise but dilutes shareholders. In a bear case, the warrants expire worthless, and the company's capital-raising capacity is diminished.
The market context matters here. Bitcoin is in a bull cycle, but the marginal buyer of Bitcoin Treasury Company equity is becoming more sophisticated. The "per-million-share BTC" metric is gaining traction as the standard valuation measure. Capital B's disclosure of this metric—while excluding multiple dilution instruments—suggests management understands the metric's importance but is selectively applying it.
The Contrarian Angle: What the Bulls Get Right
I have been harsh on the warrant structure, and for good reason. But intellectual honesty requires acknowledging what the bulls get right.
First, the immediate transaction is genuinely accretive to the company's Bitcoin holdings. The treasury increases from 3,145 to 3,415 BTC—an 8.6% increase. The company is accumulating Bitcoin at a time when institutional adoption is accelerating through ETF approvals and corporate treasury adoption.
Second, the warrant structure provides downside protection for the company. If Bitcoin enters a bear market and the share price declines, the warrants expire worthless. The company has no obligation to repurchase them. The dilution risk is contingent on share price appreciation, which is correlated with Bitcoin's performance.
Third, the European market positioning is genuinely differentiated. European institutional investors have fewer Bitcoin exposure options than their American counterparts. A regulated, listed European entity holding Bitcoin as a treasury asset fills a genuine gap. The MiCA regulatory framework provides clarity that may attract conservative European capital.
Fourth, the company's management has demonstrated capital-raising capability. The €21 million placement, combined with the €5 billion authorization, indicates access to European capital markets. This is not a trivial achievement in a market where Bitcoin Treasury Companies remain a novel concept.
The bulls' core argument is simple: Bitcoin appreciates over time, and any structure that increases corporate Bitcoin holdings will ultimately benefit shareholders. The 24.1% dilution is a cost, but if Bitcoin appreciates more than 24.1% over the warrant exercise period, shareholders still come out ahead.
This argument has merit—in a bull market. The problem is that the model has not been tested in a sustained bear market. MicroStrategy's model worked because Bitcoin appreciated from $10,000 to $70,000 during its accumulation phase. Capital B is accumulating at $80,000–$90,000. The margin of safety is thinner.
The Governance Problem: Authorization Without Accountability
The shareholder authorization of €5 billion in capital increases and €100 billion in credit instruments is a governance red flag. Management has been granted extraordinary flexibility to pursue capital raises without additional shareholder approval.
This is not inherently problematic. MicroStrategy's Michael Saylor operates with similar flexibility. But Saylor has demonstrated a consistent commitment to Bitcoin accumulation. Capital B's management has not yet demonstrated equivalent conviction.
The company's selective disclosure of dilution instruments is more concerning. Excluding the BSA series, convertible bond warrants, and TOBAM facility from the dilution calculation suggests either carelessness or deliberate obfuscation. Neither explanation is comforting.
In my experience auditing financial structures, complexity is rarely accidental. The warrant structure—four warrants per share with staggered strike prices—creates a complex web of contingent dilution that is difficult for retail investors to model. This complexity serves the issuer's interests, not the shareholder's.
The Risk Framework: What Could Go Wrong
Let me enumerate the specific failure scenarios, ranked by probability and impact.
Scenario 1: Bitcoin enters a bear market. The company's model depends on Bitcoin appreciation exceeding dilution costs. A 30% Bitcoin decline would reduce the treasury value to approximately $175 million, while the share count remains elevated. Per-share Bitcoin value declines, and the company's ability to raise additional capital diminishes. This is the highest-probability risk.
Scenario 2: Warrants are exercised without corresponding Bitcoin purchases. If the share price reaches the warrant strike prices and holders exercise, the company receives capital but has no commitment to deploy it into Bitcoin. Management could use the proceeds for operational expenses, acquisitions, or other purposes. This would constitute a 24.1% dilution without any compensating Bitcoin accumulation.
Scenario 3: Regulatory scrutiny increases. European regulators may view Bitcoin Treasury Companies as vehicles for speculative Bitcoin exposure that circumvent crypto-asset regulations. The MiCA framework's implementation could impose additional disclosure requirements or restrictions on corporate Bitcoin holdings.
Scenario 4: The narrative cools. Bitcoin Treasury Company stocks trade at premiums to their Bitcoin holdings based on the narrative of continued accumulation. If the narrative cools—due to Bitcoin underperformance or a high-profile failure in the sector—these premiums compress, and the company's ability to raise capital at favorable terms diminishes.
The common thread is the "dilution spiral." Each capital raise dilutes existing shareholders. If Bitcoin appreciation does not offset the dilution, the company must raise more capital to maintain its Bitcoin accumulation rate, which further dilutes shareholders. This feedback loop is sustainable only in a bull market.
The Takeaway: Accountability Through Transparency
The Capital B case is not unique. It represents a broader pattern in the Bitcoin Treasury Company sector: aggressive capital raising with complex dilution structures that are inadequately disclosed.
The solution is not to abandon the model. It is to demand transparency.
Investors should require Bitcoin Treasury Companies to disclose: - All dilution instruments, including older warrant series, convertible bond terms, and undrawn facilities - Committed Bitcoin purchase programs for all capital raised, including warrant exercise proceeds - Per-share Bitcoin metrics calculated on a fully diluted basis, including all contingent instruments - Management compensation tied to per-share Bitcoin growth, not total Bitcoin holdings
The metric that matters is per-share Bitcoin, not total Bitcoin. A company can increase its total Bitcoin holdings while destroying shareholder value through dilution. Capital B's 8.6% increase in total Bitcoin holdings masks a potential 24.1% decline in per-share Bitcoin.
Read the code, not the pitch deck. In this case, the code is the warrant structure, the BSA series, the TOBAM facility, and the €5 billion authorization. The pitch deck says "Bitcoin accumulation." The code says "dilution without commitment."
Complexity hides the body. The body here is the 24.1% dilution that will materialize if the warrants are exercised without corresponding Bitcoin purchases. The company's selective disclosure suggests management understands this risk and is choosing not to highlight it.
The question for investors is simple: do you trust management to deploy warrant proceeds into Bitcoin, or do you demand contractual commitments? Based on the disclosure pattern, I would not extend that trust without contractual guarantees.
The market will eventually price this risk. When it does, Capital B's shares will trade at a discount to its Bitcoin holdings, reflecting the dilution overhang. The only question is whether investors will recognize the risk before or after the warrants are exercised.
Trust nothing. Verify everything. The verification here requires reading the warrant terms, modeling the dilution scenarios, and demanding complete disclosure. The company has provided partial disclosure. The rest is hidden in the complexity.
