SERT Invests €50M Mandatory Convertible Loan in AiOnX

Why It Matters

The Amazon lease validates AiOnX’s strategy of turning former industrial sites into hyperscale‑grade data centers, while SWI’s broader asset conversions and U.S. acquisitions position it to capture soaring AI and cloud demand across both continents.

Key Takeaways

• AiOnX landed Amazon as tenant for 179 MW Dublin campus.
• €50 m ($43 m) convertible loan from SERT funds Irish development.
• First 16 MW of power available by late 2026.
• SWI aims to convert ten logistics sites into data centers across Europe.
• SWI targeting 5 GW data‑center capacity in US and Europe.

Pulse Analysis

The Amazon lease marks a watershed moment for AiOnX, turning a former meat‑processing site in Leixlip into a hyperscale‑ready cloud hub. By committing the entire 179 MW campus, the tenant not only guarantees revenue for the next two decades but also signals confidence in Ireland’s regulatory environment and power infrastructure. The early‑stage 16 MW rollout slated for late 2026 will provide a tangible foothold for further capacity expansion as AI workloads intensify.

Beyond the Irish project, SWI’s parent group is accelerating a continent‑wide conversion play. Stoneweg Europe Stapled Trust (SERT) has earmarked roughly ten logistics and warehouse locations across four European markets for data‑center retrofits, with Paris’s Parc des Docks already receiving planning approval. The €50 million convertible loan to AiOnX exemplifies how the firm is leveraging capital markets to fund rapid build‑outs while preserving upside through conversion rights. Parallel developments in Cambridge, Milan, Varde and Madrid expand the pipeline to a potential 2.25 GW, reinforcing SWI’s ambition to become a pan‑European provider.

On the trans‑Atlantic front, SWI’s acquisition of a majority stake in a U.S. Bitcoin miner underscores a strategic pivot toward high‑performance computing. The miner’s 645 MW of grid draw—and 1.3 GW of secured connections—offers a ready‑made power backbone that can be re‑engineered for AI‑grade data‑center services. Combined with three hyperscaler‑grade sites in Texas (900 MW total), the move pushes SWI’s global capacity outlook toward 5 GW. In a market where hyperscalers are scrambling for power‑rich sites to feed generative‑AI models, SWI’s blended European‑U.S. footprint could attract further marquee tenants and cement its role as a key infrastructure player.

Deal Summary

During its Q1 2026 earnings call, Stoneweg Europe Stapled Trust (SERT) announced a €50 million ($43.2 million) seven‑year mandatory convertible loan to data‑center developer AiOnX. The financing supports AiOnX’s Irish campus, which has secured a major US hyperscale tenant. The loan marks a significant funding milestone for the developer’s European expansion.
