IREN has locked in financing for 96% of the $5.81 billion GPU capital expenditure under its contract with Microsoft. The deal carries a low single-digit all-in financing cost backed by Microsoft's lease agreement. IREN also earned an investment-grade credit rating for this arrangement.
GPU Investment Scale
The $5.81 billion represents the total capital expenditure for GPUs in the Microsoft deal. This sum covers hardware purchases only, with no allocation for other costs. IREN will use the funds specifically to acquire graphics processing units for Microsoft. The entire amount is dedicated to this single project. Microsoft plans to lease the GPUs once deployed. The company secured 96% of this figure, leaving 4% still unfunded. That remaining portion must be covered before full expenditure. The capital outlay is significant for this specific agreement. No other projects will draw from these funds. IREN must finalize the financing to meet Microsoft's requirements.
Financing Terms
The 96% financing comes at a low single-digit all-in cost. This rate includes all fees and interest components. The pricing reflects the deal's secured structure. Microsoft's lease agreement provided the foundation for this rate. Lenders accepted the terms due to the backing. The low single-digit figure is favorable for such a large sum. IREN locked in the cost for the vast majority of the expenditure. The remaining 4% requires separate funding arrangements. This portion carries no specified cost yet. The company must secure this final piece soon. The existing terms won't apply to the unfunded portion.
Microsoft's Backing Role
Microsoft's lease agreement was central to the financing structure. IREN used it as primary security for the arrangement. The agreement demonstrated a reliable revenue stream to lenders. This backing reduced perceived risk significantly. Microsoft's commitment enabled the investment-grade rating. The lease terms provided collateral for the full $5.81 billion. Without this, the financing would have cost more. The backing was non-negotiable for the deal's structure. Lenders required Microsoft's involvement. The agreement made the low single-digit rate possible. IREN relied entirely on this Microsoft partnership.
Credit Rating Outcome
IREN received an investment-grade credit rating for this specific financing. The rating applies only to this Microsoft-backed arrangement. It signals strong security to lenders and investors. Investment-grade status is uncommon for single-project financings. The rating directly resulted from Microsoft's lease backing. This distinction lowered the all-in cost. It made the deal more attractive to capital providers. IREN can leverage this rating for future transactions. The achievement validates the deal's structure. However, it covers only the secured 96% portion. The remaining 4% has no such rating yet.
The company must now secure the remaining 4% of the capital expenditure.
