When a Bitcoin treasury company's own math reveals a structural contradiction between narrative and shareholder value.
On August 31, Capital B—a European-listed Bitcoin treasury company—will deliver 36.2 million new shares to private placement investors at €0.58 per unit, raising €21 million earmarked for the purchase of approximately 270 Bitcoin. On the surface, this appears to be a routine capital raise by a company following the playbook that MicroStrategy made famous: issue equity, buy Bitcoin, repeat.
But beneath that deceptively simple transaction lies a complex warrant structure that could reduce the company's per-share Bitcoin exposure by 24.1% if fully exercised. The company's own disclosure numbers, when laid side by side, tell a story that deserves far more scrutiny than it has received.
The Mechanics of Dilution
Capital B is not a blockchain protocol. It does not run validators, maintain a sequencer, or ship smart contracts. It is a publicly traded corporate vehicle designed to hold Bitcoin on its balance sheet—a financial instrument layer in the crypto ecosystem, nothing more and nothing less.
Its "technology" is the capital markets structure it employs to accumulate Bitcoin. And in this particular case, that structure involves attaching four warrants to every new share issued. These warrants carry exercise prices of €0.75, €0.98, and €1.27, with a five-year duration. They are, in traditional finance terms, sweeteners for private placement investors—but for existing shareholders, they represent a contingent dilution event of significant magnitude.
Let me walk through the numbers, because they matter more than any narrative.
The company currently holds 3,145 BTC. After this placement, assuming the Bitcoin is purchased as stated, the treasury will hold approximately 3,415 BTC. The placement adds 36,219,070 new shares. On a spot basis—just the shares, no warrants exercised—the per-million-share BTC ratio moves from 7.4725 to 7.4711. That's a change of negative 0.02%. Essentially neutral, as the company has claimed.
But here's where the story gets uncomfortable. If all 144,876,280 warrants attached to this placement are exercised, the share count balloons dramatically. The per-million-share BTC ratio collapses to 5.6730—a 24.1% decline in per-share Bitcoin exposure.
That is not a rounding error. That is not noise. That is a structural transfer of value from existing shareholders to warrant holders, executed with the precision of a well-designed financial instrument.
The Warrants Are the Story
The company's framing suggests this raise improves "diluted Bitcoin holdings per share." In the narrowest sense, at the spot level, that's technically correct—barely. But the warrant structure tells a different story about where management's incentives actually lie.
Consider the exercise prices: €0.75, €0.98, and €1.27. The placement price is €0.58. These warrants are priced at a 29% to 119% premium to the current placement price. The company is implicitly signaling that it expects the stock to appreciate significantly over the next five years. If that happens, warrants get exercised, new shares hit the market, and existing shareholders get diluted.
If the stock doesn't appreciate? The warrants expire worthless, and the company doesn't receive the additional capital. Either way, existing shareholders bear the cost structure of this arrangement.
Based on my experience auditing financial mechanisms in this industry, this is a textbook case of asymmetric risk allocation. The company gets its €21 million now. The investors get their Bitcoin exposure, plus warrants that offer meaningful upside if the stock performs. The existing shareholders get... the promise that the spot dilution is "neutral," while the full dilution picture reveals a 24% haircut to their proportional Bitcoin claim.
What the Company Isn't Disclosing
Here's what troubles me most. The company's dilution calculations exclude several categories of potentially dilutive instruments.
There are the older BSA-series warrants—terms undisclosed. There are warrants attached to convertible bonds—again, terms undisclosed. There's the TOBAM program with €300 million in unissued capacity. Any one of these could add further dilution pressure on top of the 24.1% already identified.
This is not a complete picture. It's a partial disclosure that happens to show the most favorable numbers.
The company does report one thing clearly: in June, shareholders authorized €5 billion in capital increases and €100 billion in credit instruments. Those are staggering numbers for a company holding roughly 3,400 Bitcoin. They suggest management has both the authority and, potentially, the appetite for a far larger dilution cycle than anything seen so far.
A Pattern That Bears Watching
Capital B is not alone in this game. MicroStrategy pioneered the Bitcoin treasury model, and its use of convertible notes—which do not dilute existing shareholders until conversion actually occurs—has been notably more shareholder-friendly than Capital B's immediate warrant attachment.
Metaplanet in Tokyo and Boyaa Interactive are also running variants of the same playbook. But Capital B's structure, with four warrants per share and undisclosed additional instruments, represents the more aggressive end of the dilution spectrum.
The broader pattern is worth naming, even if the industry prefers not to discuss it: Bitcoin treasury companies are, in essence, leveraged Bitcoin plays. They raise equity, buy Bitcoin, and hope the appreciation outpaces the dilution cost. In a bull market, this feels like a perpetual motion machine. In a bear market, the cycle reverses—falling Bitcoin prices make further equity raises less attractive, which limits Bitcoin purchases, which reduces the narrative appeal, which pressures the stock further.
The Terra collapse of 2022 taught us what happens when crypto's financial engineering relies on asset prices moving in one direction. The mechanisms are different here, but the structural dependence on continued appreciation is similar.
What Investors Should Watch
For anyone holding Capital B stock, or considering it, the key metrics to track are straightforward.
First, monitor warrant exercise announcements. If we see exercise rates above 50%, the per-share Bitcoin ratio will compress meaningfully. Second, watch for additional financing announcements—particularly anything close to the €500 million scale, which would signal that the authorized capital increases are being deployed. Third, compare Capital B's per-share Bitcoin ratio against MSTR's on a regular basis. That ratio is the fundamental measure of value in this sector, and it's the one most likely to reveal structural weakness.
The Structural Question
The deeper question this raises is about the Bitcoin treasury model itself. When a company's core value proposition is "hold Bitcoin for shareholders," the per-share ratio of Bitcoin is the only metric that truly matters. Everything else—total treasury holdings, narrative strength, market positioning—is secondary.
Capital B's raise increases total treasury holdings by 8.6% while leaving per-share exposure essentially flat on a spot basis. That is not growth. It is, at best, stasis, with a 24% dilution bomb attached for the long term.
Quietly securing the layers beneath the hype means reading the disclosures that companies don't want to emphasize. In this case, the story is in the warrants, the undisclosed instruments, and the massive authorized capital that hasn't been deployed yet. Building trust through rigorous, unseen diligence requires asking the uncomfortable question: what does this deal actually do for existing shareholders?
The answer, after working through the math, is considerably less than the headline suggests. The 24.1% dilution risk is real, it is structural, and it has been framed in the most favorable possible light.
Tracing the hidden vulnerabilities in the code—or in this case, the capital structure—reveals that the real risk isn't Bitcoin's price volatility. It's the slow, steady erosion of per-share value through carefully designed financial instruments that benefit new investors at the expense of existing ones.
The question investors should be asking isn't whether Bitcoin will appreciate. It's whether Capital B's warrant stack—current and undisclosed—will devour the gains before they reach their portfolio.
Hype fades. Code remains. And in the world of Bitcoin treasury companies, the code is the capital structure itself.
