IREN Expands AI Data Center Push With 490MW Europe Acquisition

Shares of IREN ($IREN) rose about 3.2% after the company said it has completed the acquisition of Spain-based Nostrum Group (Ingenostrum), a deal that significantly expands IREN’s footprint in Europe’s fast-growing AI data center market. The move adds roughly 490 megawatts (MW) of power capacity tied to European AI data center development—an increasingly scarce asset as hyperscalers and model developers scramble for power-secured sites.

The stock closed at $59.96, after touching an intraday high of $61.51. IREN remains sharply higher over the past year, up roughly 472% from its 52-week low of $9.83, reflecting the market’s re-rating of the company from a cyclical crypto miner to an emerging AI infrastructure operator. In after-hours trading, shares held around $60.03, suggesting demand remained intact following the news.

By bringing Nostrum into the fold, IREN strengthens its message that the company’s future is no longer defined primarily by Bitcoin (BTC) mining. Analysts increasingly describe IREN as pursuing a vertically integrated AI infrastructure platform—combining power procurement, GPU-focused data center operations, and direct sales to hyperscaler-type customers—at a time when AI compute bottlenecks are often constrained more by electricity and grid access than by chips alone.

The newly secured 490MW is also being framed by investors as a meaningful piece of IREN’s broader global power ambition. The company has pointed to a long-term target of a 6-gigawatt (GW) power portfolio, positioning grid-connected capacity as a core strategic advantage in negotiations with large technology customers seeking long-duration compute availability. With operating bases in Australia and Canada, the European expansion gives IREN a presence across three continents—an attribute that can appeal to customers looking to diversify latency, regulation, and energy-price exposure across regions.

Jefferies recently initiated coverage on IREN, describing it less as a pure-play crypto mining stock and more as an 'AI infrastructure growth' name. The bank, however, also highlighted the balance of opportunity and risk typical for data center buildouts: large upfront capital requirements, execution complexity, and uncertainty around the timing of cash flow as facilities come online and customer capacity 'ramps up' over time.

Longer-term forecasts circulating in the market remain optimistic. Some projections estimate IREN could generate around $5.6 billion in revenue and $183.6 million in net income by 2029, contingent on successful conversion of its power and facilities roadmap into contracted AI infrastructure services. For equity investors, those numbers underscore why the market has rewarded firms perceived to be moving into AI compute supply—while also raising the stakes for delivery against construction timelines and utilization assumptions.

IREN has also emphasized its power infrastructure advantages in South Australia, where it holds multiple 330kV transmission connection points—an important factor for high-density AI workloads that require stable, scalable electricity supply. Adding European capacity may give the company more flexibility to pursue load-balancing across regions, potentially smoothing operational constraints tied to local grid conditions or energy market volatility.

In the near term, traders appear focused on two catalysts: when European sites will begin meaningful operations and how quickly contracted AI capacity can scale. Investors also see potential upside in pairing AI data center operations with relatively efficient European grids, which could support lower operating costs and reduced carbon intensity compared with less efficient power mixes elsewhere—an increasingly relevant consideration for enterprise customers and regulators.

Trading activity reflected the heightened attention. Volume reached about 37.96 million shares, well above typical levels. The stock opened near $61.29, briefly climbed to $61.51, then pulled back toward $58 amid profit-taking before recovering into the close. From a technical perspective, IREN is still roughly 22% below its 52-week high of $76.87, leaving room for further upside in bullish scenarios, though some market participants continue to flag near-term overheating risk and uncertainty around the payback period for rapid AI infrastructure expansion.

More broadly, IREN’s repositioning mirrors a wider shift across the crypto mining sector. As post-halving dynamics, rising network difficulty, and competitive pressures compress mining economics, several operators are attempting to repurpose power access and industrial-scale facilities toward AI data centers. For the market, the Nostrum acquisition is being interpreted as a concrete step in that transition—one that could set the stage for additional M&A or partnership announcements as IREN competes for a larger role in the global AI compute supply chain.
