Capital B's €67.5 M Bitcoin Impairment: What IFRS Reporters Must Know
Capital B: The Numbers Behind the Loss
Capital B, which rebranded from The Blockchain Group in July 2025 to signal its pivot toward a dedicated bitcoin treasury strategy, posted the following headline figures in its H1 2026 results:
| Metric | H1 2026 | H1 2025 |
|---|---|---|
| Net loss | €69.5 M ($78.1 M) | €1.9 M ($2.1 M) |
| Of which: bitcoin impairment charge | €67.5 M ($75.9 M) | Not disclosed |
| Revenue | €5.8 M ($6.5 M) | €5.6 M |
| Revenue growth (YoY) | +3.5% | — |
The company was explicit that the impairment charge carried no cash impact. Its operating business, generating €5.8 million in revenue, actually grew modestly. The loss is an accounting construct produced by the interaction of the company's balance-sheet bitcoin position and the measurement rules it is required to follow under IFRS.
Bitcoin Reserve Growth and Capital Raises
Despite the headline loss, Capital B continued to accumulate bitcoin throughout the period. Its strategic reserve reached 3,538 BTC as of 30 September 2026, up 25.3% from 2,823 BTC at the start of January. Total acquisition cost stood at €310.6 million ($349.4 million), averaging €87,805 ($98,768) per coin. The company also reported a BTC yield, defined as the percentage change in bitcoin holdings per fully diluted share, of 2.2% for the first nine months of 2026.
To finance that accumulation, Capital B completed capital raises totalling €27.5 million ($30.9 million) during H1 2026, followed by a further €31.7 million ($35.6 million) between 1 July and 15 October. The company's largest single purchase of the year, executed in September, totalled €25.3 million ($28.4 million).
The IFRS Problem: Why Impairment Hits Hard
Capital B reports under IFRS. Under current IFRS guidance, most corporate bitcoin holdings are classified as intangible assets and accounted for under IAS 38. That standard allows two measurement models after initial recognition: the cost model and the revaluation model. In practice, the revaluation model is only available where an active market exists in the standard's specific sense, and even where it is applied, downward revaluations below cost flow through profit or loss immediately.
The Asymmetry of IAS 38 for Bitcoin
Under the cost model, which is what many IFRS bitcoin holders apply, an asset is carried at cost less any accumulated impairment losses. If bitcoin's market price falls below the carrying amount, an impairment must be recognised in profit or loss. If the price subsequently recovers, the reversal is permitted under IAS 38 only up to the originally impaired amount, and only if the conditions that led to the impairment have reversed. The result is a system that is structurally asymmetric: declines in bitcoin's market price create immediate income statement charges, while price appreciation above the written-down carrying value is invisible until the asset is sold.
That asymmetry is exactly what Capital B's H1 results illustrate. The company holds a large and growing bitcoin position. A price move that reduced market value below carrying value on 30 June 2026 generated a €67.5 million charge, wiping out years of operational progress in a single reporting line. The business itself, measured by revenue, actually grew. The divergence between accounting loss and economic reality is not incidental; it is embedded in the standard.
How IAS 21 and the Euro Add Another Layer
Capital B reports in euros. Bitcoin is priced globally in US dollars. That introduces a second variable: euro/dollar exchange rate movements affect the euro-denominated carrying value of BTC holdings independently of bitcoin's dollar price. An appreciation of the dollar against the euro will increase the carrying value in euros; a weakening will reduce it. Auditors reviewing impairment testing for any European bitcoin treasury must therefore assess both the bitcoin price and the relevant exchange rate at each reporting date, and document clearly how the two interact in the impairment calculation.
FASB's ASC 350-60: The Fair-Value Alternative
US GAAP reporters have a materially different experience. In late 2023, the Financial Accounting Standards Board issued ASU 2023-08, codified as ASC 350-60, which requires entities that hold certain crypto assets, including bitcoin, to measure them at fair value each reporting period, with changes recognised in net income. The standard became effective for fiscal years beginning after 15 December 2024.
What ASC 350-60 Changes in Practice
Under ASC 350-60, a US GAAP reporter holding bitcoin will recognise both price declines and price increases in the income statement each period. That symmetry means the P&L is more volatile, but it also means that a company that bought bitcoin at a given price and has seen that price rise will show a gain, whereas an IFRS reporter in the same position is still carrying the asset at cost (or at a previously impaired value) with no income statement credit. The contrast with Capital B's situation is direct: a hypothetical US GAAP entity with an identical bitcoin position could have reported a net gain in the same period if bitcoin's fair value on 30 June 2026 exceeded its carrying value.
For accounting firms advising clients on digital asset accounting software or on the structure of their bitcoin treasury, the choice of reporting framework, or the choice of jurisdiction in which a holding entity is domiciled, has become a significant financial reporting decision in its own right. This is a live consideration for any CFO evaluating bitcoin accounting across multiple subsidiaries reporting under different GAAPs. It also speaks to the broader question of how IFRS bitcoin accounting will evolve: the IASB's own project on crypto assets, which produced the June 2023 amendments to IAS 38 creating a narrow scope exception for certain holdings measured at fair value through profit or loss, is a partial response, but it applies only to assets held for sale in the ordinary course of business, not treasury reserves of the kind Capital B holds.
Implications for Auditors and CFOs
Capital B's H1 results create a useful checklist for practitioners advising IFRS entities with bitcoin on the balance sheet.
Impairment Testing and Documentation
The impairment trigger under IAS 36 (applicable to intangible assets where IAS 38's own impairment indicators are present) requires an assessment at each reporting date of whether there is any indication of impairment. For bitcoin, the most obvious indicator is a decline in market price below carrying value. Audit teams should ensure that: the price used is consistent with the definition of fair value under IFRS 13 (the price in the principal or most advantageous market); the measurement date corresponds precisely to the reporting date; and the recoverable amount calculation is properly documented. Given the volatility of bitcoin prices, the date of the impairment test matters enormously: a price sampled even a few days early or late can produce a materially different result.
Disclosure Quality
IAS 38 requires disclosure of the carrying amount, the amortisation method, and the useful life or the fact that the asset is treated as having an indefinite useful life. For impaired assets, IAS 36 requires disclosure of the amount of the impairment loss, the events and circumstances that led to the recognition, and whether the recoverable amount is based on fair value less costs of disposal or value in use. Capital B's explicit statement that the charge had no cash impact is good practice; it frames the number correctly for investors. Auditors should check that similar language appears in client financials and that notes adequately explain the measurement methodology.
Board-Level Reporting and KPIs
Capital B uses BTC yield as a supplementary KPI to communicate the per-share efficiency of its bitcoin accumulation strategy. This type of non-IFRS metric is becoming common among bitcoin treasury companies. Accounting firms advising clients in this space should help boards understand both the utility and the limitations of such metrics: they are not audited, they are not standardised across entities, and they sit outside the primary financial statements. Disclosure of how the metric is calculated, and a clear reconciliation to audited figures, is essential to avoid misleading stakeholders.

Frequently Asked Questions
Why does an impairment charge produce a loss even if no bitcoin was sold?
Under IAS 38 (cost model), the carrying value of an intangible asset must be written down to its recoverable amount when that amount falls below the carrying value. The write-down is recognised as an expense in profit or loss regardless of whether the asset has been disposed of. No cash changes hands; it is purely an accounting adjustment reflecting the lower market value at the reporting date.
Can Capital B reverse the impairment if bitcoin's price rises?
IAS 38 permits reversal of an impairment loss on an intangible asset only if the events or circumstances that caused the impairment have reversed. Even then, the reversal cannot exceed the original impairment amount, meaning the asset cannot be written back above its historical cost. Any further appreciation in bitcoin's value beyond the reversal cap will not appear in the income statement until the asset is sold.
How does ASC 350-60 treat the same situation for a US GAAP reporter?
Under ASC 350-60, applicable to fiscal years beginning after 15 December 2024, qualifying crypto assets including bitcoin are measured at fair value each period, with all changes, both gains and losses, recognised in net income. A US GAAP entity holding the same bitcoin as Capital B would report gains in periods where price rises and losses in periods where price falls, producing a symmetric but more volatile income statement compared with the IFRS impairment-only model.
What is BTC yield and is it an audited figure?
BTC yield, as used by Capital B, measures the percentage change in the company's bitcoin holdings per fully diluted share over a given period. It is a company-defined, non-IFRS metric and is not subject to audit in the same way as primary financial statement figures. Its purpose is to show whether bitcoin per share is growing, independently of the euro price of bitcoin. Users of financial statements should treat it as supplementary information and request a clear explanation of the calculation methodology from management.
Should French companies consider reclassifying bitcoin under a different IFRS category?
The June 2023 IASB amendments to IAS 38 introduced a narrow fair-value-through-profit-or-loss exception for crypto assets held for sale in the ordinary course of business. A bitcoin treasury reserve, held as a strategic asset rather than inventory, is unlikely to meet that criterion. Some entities have explored whether bitcoin could qualify as a financial asset under IAS 32/IFRS 9, but the IASB has generally concluded that crypto assets lack the contractual rights that would bring them within that scope. Any reclassification would require careful legal and accounting analysis and should be discussed with auditors before implementation.
