IREN has closed a $3 billion convertible senior notes offering as it continues to fund its AI cloud expansion.
Summary
- IREN raised $3 billion through 1.00% convertible senior notes due in 2033.
- Net proceeds of about $2.96 billion will support capped calls, working capital and corporate needs.
- The raise follows IREN’s Nvidia and Microsoft AI cloud deals, which raised funding demands.
The notes carry a 1.00% coupon and mature in 2033. The deal included a $2.6 billion base offering and a fully exercised $400 million greenshoe option.
The company said net proceeds came to about $2.96 billion after fees and expenses. IREN plans to use $201.3 million to fund capped call transactions, with the rest set aside for general corporate needs and working capital.
Meanwhile, the capped call deals are tied to the notes and are expected to reduce potential dilution if the debt converts into shares. IREN said the capped call cap price starts at $110.30 per share, which is 100% above the $55.15 share price recorded on May 11.
The company also said the notes have a 32.5% conversion premium and no investor put option, except in certain standard change-of-control cases. The offering was sold privately to qualified institutional buyers under Rule 144A.
AI cloud deals raise funding needs
The raise comes days after IREN announced a five-year, $3.4 billion AI cloud deal with Nvidia. According to earlier reports, Nvidia also received a five-year warrant to buy up to 30 million IREN shares at $70 each.
The Nvidia agreement followed IREN’s earlier $9.7 billion Microsoft deal for GPU cloud infrastructure. Market updates noted that those two partnerships pushed IREN’s committed revenue above $15 billion, as the company targets large-scale AI data center growth.
IREN shifts further from Bitcoin mining roots
IREN, formerly known as Iris Energy, started as a Bitcoin mining company. It has since moved toward what it calls a “Neocloud” model, using energy and data center sites to serve AI workloads.
Earlier reports said investors had already focused on funding risk as IREN moved deeper into GPU-heavy infrastructure. The company’s plan to scale AI cloud services requires major capital, and the latest note sale gives it a larger cash base for that buildout.
Moreover, IREN said its AI cloud platform is built around large-scale data centers and GPU clusters for AI training and inference. The company also said its sites are backed by grid-connected land and power across North America, Europe and APAC.
The release also cautioned that plans for the proceeds remain forward-looking. IREN said it cannot give assurances on how effectively it will use the funds after paying for the capped call transactions.
