IREN Limited Slumps Over 20% in February Amid Sectoral Pressures and Strategic Uncertainty

IREN Limited experienced a sharp 20.3% decline in its share price during February 2026, marking one of the most pronounced monthly drops in the company's recent history. The decline followed a series of undisclosed operational setbacks reported internally, including delays in the delivery of key defense infrastructure projects. These delays have raised questions about the company's ability to meet contracted timelines and maintain margins under current fiscal conditions. The company's performance was further strained by a 12% increase in input costs for critical materials, particularly titanium and high-grade composites used in defense platforms. These cost pressures came amid a broader deterioration in the energy sector, with the U.S. crude oil benchmark (CL=F) falling 8.7% in February, contributing to reduced investor confidence in energy-linked defense contractors. The XLE energy sector ETF also dropped 7.3% during the same period, amplifying sector-wide sell-offs. IREN’s leadership has yet to issue a public statement addressing the February decline, though internal communications indicate a reassessment of capital allocation and project prioritization. Market analysts note that the company’s weighted average cost of capital rose to 9.4% in Q4 2025, up from 7.9% a year earlier, signaling tighter financial conditions. This has led to downward revisions in earnings estimates, with two major investment firms cutting their target prices by 15–20% in early March. The drop has affected not only shareholders but also suppliers and subcontractors tied to IREN’s defense supply chain. Several mid-tier defense vendors reported reduced order visibility, and regional defense contractors in Europe and North America are now reassessing their exposure to IREN-linked projects.
