Capital B Is Compounding Coins and Diluting Shareholders

A Paris-listed company whose entire business model is holding Bitcoin just raised €21 million to buy about 270 more of them. On August 28, Capital B — Europe's first listed "Bitcoin treasury company," the former The Blockchain Group, ticker ALCPB on Euronext Growth Paris — placed 36.2 million new shares at €0.58 each, and says the cash "could enable" the acquisition of roughly 270 bitcoin, taking its hoard from 3,145 to about 3,415 BTC.

That headline number — 3,415 — is the wrong one. For anyone tempted to buy this stock as a way to own Bitcoin, the figure that matters is Bitcoin per share, and that figure just went sideways, not up. The gap between the two numbers is the whole investment story.

What this company is

Capital B runs the playbook that made Strategy (formerly MicroStrategy) the defining corporate trade of this cycle: raise capital by selling its own stock, buy Bitcoin, hold it forever. Its mission statement is frankly maximalist — "accumulate as much Bitcoin as possible, as fast as possible, in the most accretive way possible" — with public targets of 15,000 BTC by the end of 2027 and 210,000 BTC, one percent of all Bitcoin that will ever exist, by 2033. It adopted its "Bitcoin Standard" in November 2024 and rebranded from its old consulting-company identity to signal exactly what it now is.

Here is the mechanism debt-and-equity treasuries live or die on. A treasury company creates value for shareholders only when it raises money at a price above the value of the Bitcoin already behind each share. Strategy's trick in 2024–25 was exactly that: because its shares traded at a large premium to the coins on its balance sheet, every time it issued stock, it bought more Bitcoin per share than existed a moment earlier. Issuance compounded. That premium is the flywheel, and the metric it feeds is Bitcoin per fully diluted share — the industry even has a name for it: "BTC yield."

Now run Capital B's numbers

Capital B's stock trades at roughly the value of its Bitcoin — not a premium. The company owns 3,145 BTC worth about €215 million at current prices. The entire company — that hoard, plus its data-and-AI consulting arm and its cash — carries a market capitalization of about €206 million. The market is paying slightly less than face value for the coins and nothing for the structure.

Inside this deal, the same flat math. New investors put in €21 million gross (€19.9 million after fees) for 36.2 million new shares — about 11% more shares — at €0.58, a 6.45% discount to the prior day's €0.62 close. That buys roughly 270 coins, or about 8.6% more Bitcoin. Shares grow faster than coins, so each existing share's slice of the hoard thins by a couple of percent. It is not a round that destroys value; it is a round that fails to create it, which is a strange thing for an "accretive" strategy to do.

Each share came bundled with four five-year warrants, 144.9 million in total, exercisable at €0.75, €0.98, and €1.27 — that is, at 30% to 120% above the current price. If they are ever all exercised, they shower the company with another €135.8 million, with a forced-exercise clause if the stock runs past 130% of a strike for 20 trading days. The warrants are the real instrument here: a built-in bet that ALCPB will one day trade at a premium to its coins, at which point the flywheel finally engages and more cash converts into still more coins. Today that premium does not exist.

The treadmill underneath

This is one round in a serial-issuance program, and the pattern is what makes it uncomfortable. In late March the company had about 230 million shares; by late August roughly 333 million existed, with more warrants outstanding than shares. The price of the new money has fallen with each round: €0.60 in an April at-the-market sale, €0.66 in the May placement, €0.47 in a mid-August ATM sale, €0.58 now.

Set the equity against the asset. Bitcoin is about 37% below the $125,000 high it touched last October. ALCPB is about 70% below its own 52-week high of €2.02. The stock has lost more than twice as much as the coin — that difference is the cost of running the machine. And the coins themselves are bought high: the 3,145 now on the balance sheet cost an average of about €90,000, roughly a third above today's price. That positioning produced a €53.9 million Bitcoin impairment and a €62.2 million net loss in 2025 — mostly a non-cash markdown, but a permanent one under the accounting rules it uses.

Whose money is doing this

The two named "strategic investors" are telling. Adam Back, Blockstream's co-founder and the only person cited in the original Bitcoin whitepaper, is increasing his stake from 12% to 14.82% — he is buying into this round. TOBAM, the Paris asset manager, goes from 2.87% to 3.29%. But Blockstream Capital Partners, the affiliated fund that is still the largest holder at about 19.6%, did not subscribe, and every other shareholder is diluted by roughly 10% before the warrants even get counted. Coming a week before a 10-for-1 reverse stock split aimed at widening the investor base, this reads as insiders funding the machine while they tidy the share price for a broader audience. If you are a U.S. retail investor, note that access is already thin: this is a small Euronext Growth listing, the placement was not registered with the SEC, and U.S. investors face the thinly traded OTC line instead.

The honest read

Steelman first, because it deserves one. If Bitcoin rallies hard, the leverage works in the holder's favor; if the stock then re-rates to the premium the warrants are priced for, a €0.75–€1.27 strike becomes cheap, forced exercise pours money in, and per-share Bitcoin finally compounds. Adam Back, who has been early on Bitcoin's macro story for fifteen years, is deliberately staying in the deal. That is a real asymmetry the participants are paying for: limited-looking downside in the raise discount against uncapped upside if the market grants the premium.

But the data so far argues the other way. The stock has been the losing side of the trade in every window since the strategy began, the per-share pile has thinned with each raise, and a company that must reach 210,000 coins by 2033 — 61 times today's hoard — will need to keep selling shares, which keeps diluting, at whatever premium or discount the market grudgingly provides. Buying the equity to participate in Bitcoin means paying a toll (fees, dilution, accounting drag) that buying the coin does not. The only scenario in which the equity wins materially is the one that has not yet appeared in the price: ALCPB trading above the value of the Bitcoin it owns.

Keep one checkpoint after every treasury-company announcement, this one included. Take the coins, divide by the fully diluted share count, and compare that to where the fresh shares were priced. Premium to backing means the flywheel is spinning and each raise adds coins per share. Discount to backing means the announcement is a transfer from existing holders to the new buyers — and the "3,415 BTC" in the headline was the transfer document.
