Capital B said it bought 5 BTC for EUR280,000 on Aug. 17, 2026, lifting its strategic treasury to 3,145 BTC after raising about EUR301,460 through the issuance of 647,110 shares under its agreement with TOBAM. The company valued the reserve at EUR170.9 million versus a EUR284.2 million acquisition cost, reported 61 BTC held separately for operations, and said Blockstream Capital Partners had converted all OCA B-01 instruments into equity. The disclosure came as SoSoValue data showed weekly net Bitcoin buying by listed companies excluding miners fell 90.34% to $5.32 million, with Capital B and Strive the only reported buyers, while Strategy repurchased $132 million of STRC preferred shares and Metaplanet made no purchase for a fifth straight week.
