What to know:

  • H100 secured 150 million kronor (around $15 million) from Blockstream CEO Adam Back in the first tranche of its funding round.
  • H100 plans to raise up to 750 million kronor across three tranches to support its bitcoin investment strategy.
  • The three-part tranche model allows for responsive capital deployment based on market conditions.
  • A convertible-loan structure offers fast, flexible capital with strategic alignment from key backers.

H100 Group (H100), a Swedish health-technology company, said it reached an agreement that could see Blockstream CEO Adam Back lend it as much as 750 million kronor ($79 million) to support its long-term bitcoin treasury strategy.

Back signed up for an initial 150 million-krona tranche, known as Tranche 6, of a convertible loan. He also holds a right to participate in two follow-up tranches, each currently set at 75 million kronor, though the company intends to that amount if market conditions allow.

The financing structure prioritizes speed and cost-efficiency over a traditional rights issue and allows Stockholm-based H100 to invite other investors on equal terms. Convertible loan terms were set through arm’s length negotiations, with Tranche 6 priced at 6.38 kronor per share, a 33% premium to market.

"Unexpectedly, given the strong reception, Tranches 1-4 became in-the-money rapidly," Back said in a statement to CoinDesk. "I was expecting [H100] would convert them over time as they reached in-the-money status".
H100 Group currently holds 24.41 BTC, according to BitcoinTreasuries.net. The company's shares 22% on Monday.
