Capital B’s H1 loss widens to €69.5M as non-cash bitcoin impairment collides with an aggressive treasury build

Capital B is leaning into its bitcoin-first playbook, and the income statement is bearing the optics. The French bitcoin treasury firm reported a sharply wider first-half net loss largely due to a non-cash impairment tied to BTC’s June 30 price, even as it continued to scale its reserves and tap fresh capital.

For the first six months of the year, net loss came in at €69.5 million ($78.1 million), versus €1.9 million ($2.1 million) a year earlier. About €67.5 million ($75.9 million) of that was an additional bitcoin impairment, which the company said had no cash impact. Revenue edged up 3.5% year over year to €5.8 million ($6.5 million), compared with €5.6 million in the first half of 2025.

The balance-sheet story moved the other way. By Sept. 30, Capital B’s strategic reserve reached 3,538 BTC, up 25.3% from 2,823 BTC in January. Cumulative acquisition cost totaled €310.6 million ($349.4 million), implying an average purchase price of €87,805 ($98,768) per bitcoin. The firm also cited a 2.2% BTC yield for the first nine months—a per-share metric that tracks the percentage change in bitcoin holdings on a fully diluted basis.

Funding has been steady. Management disclosed €27.5 million ($30.9 million) of capital raises in the first half and another €31.7 million ($35.6 million) between July 1 and Oct. 15. In September, the company executed its largest buy of the year—376 BTC for €25.3 million ($28.4 million)—financed from recent raises that included investments from Blockstream CEO Adam Back. The business, rebranded from The Blockchain Group in July 2025, remains centered on a bitcoin treasury strategy.

The single variable that matters here is not quarter-to-quarter accounting noise—it’s the per-share compounding of BTC. The headline stack grew 25.3% year to date, yet management’s own yardstick shows a 2.2% increase per fully diluted share over nine months. That spread likely reflects the cost of accessing capital: new equity (and potentially other instruments) funds accumulation but dilutes the claim on each coin. If the firm cannot grow BTC per share faster than dilution, the strategy risks becoming a treadmill—bigger absolute holdings with limited owner-level accretion.

Impairment adds another layer. Because the charge is non-cash and price-anchored on a specific date, reported earnings will often diverge from economic reality—especially in a volatile asset like BTC. That can weigh on sentiment, elevate financing costs, and force management to spend time explaining accounting mechanics instead of reinforcing the long-term thesis. Conversely, visible support from industry figures and consistent access to capital can counterbalance that pressure, provided subsequent deployments lift per-share BTC.

What to watch next: - BTC per-share growth versus the pace and terms of new raises - The gap between the average acquisition cost (€87,805 per BTC) and spot price - The sustainability of revenue (€5.8M in H1) relative to the scale of treasury operations - Execution of large buys (e.g., September’s 376 BTC) without eroding per-share accretion

Capital B is clearly prioritizing scale. Whether that translates into durable value depends on narrowing the dilution gap and letting the treasury do what it’s designed to do: drive per-share BTC higher through cycles.
