Sydney-based bitcoin miner IREN has announced plans to raise $400 million (3.25% coupon, 30% conversion premium) by issuing a convertible bond, an increase from the previously announced principal amount of the $300 million note, the issue and sale of which is scheduled to settle on December 6, 2024, subject to customary closing conditions. In addition, IREN said it plans to expand its bitcoin mining capacity to 50 EH/s by the first half of 2025.
