The company’s cumulative spend on its treasury now stands at €284.2 million, with an overall cost basis of €90,352 per BTC. Alongside the new purchase, Capital B confirmed the successful conversion of 14,195,352 Blockstream-held OCA B-01 convertible instruments into ordinary shares.
The Importance of “BTC Yield” metric
To measure the growth of its holdings relative to share issuance, Capital B utilizes the “BTC Yield” metric, a reporting framework popularized by MicroStrategy. For the current year-to-date, the firm reported a BTC Yield of 2.14%, a BTC Gain of 60.3 Bitcoin, and a BTC Euro Gain of €3.3 million.
This latest activity places Capital B among the larger public Bitcoin holders in Europe. While the firm currently holds 3,145 BTC, other entities in the region have also adjusted their positions. Recent market data indicates that H100 Group AB has increased its stack to 3,506 BTC through a stock-based acquisition of NSD AS, while Germany’s Bitcoin Group SE maintains a treasury of approximately 3,605 BTC.
The expansion of the Capital B treasury reflects a continuing trend of public companies utilizing equity markets to fund direct Bitcoin acquisitions. The firm has grown its holdings from approximately 2,000 BTC in mid-2025 to its current level as it pursues its stated ambition of scaling its dedicated Bitcoin balance sheet.
