European corporate profit margins are finally headed in the right direction. After years of contraction driven by falling commodity prices and rising labor costs, blue-chip firms across the continent are projected to post their strongest earnings growth since late 2022, powered by an unlikely duo: resurgent energy prices and the insatiable appetite for artificial intelligence infrastructure.
LSEG data published on May 15 shows European blue-chip earnings are expected to grow 11.5% year-on-year in Q1 2026. That figure represents the highest quarterly growth rate since Q4 2022, when margins were still riding the tail end of a post-pandemic commodity boom before the long slide began.
The AI factor is doing real work
Aixtron, the German semiconductor equipment manufacturer, has surged 189% year-to-date as of May 2026. STMicroelectronics, the Franco-Italian chipmaker, isn’t far behind with a 133% gain over the same period. These aren’t speculative plays on vaporware. They’re companies directly tied to the physical buildout of AI infrastructure: chip fabrication equipment, data center components, the nuts-and-bolts hardware that makes large language models actually run.
The demand pipeline for data center projects across Europe has created a ripple effect through the semiconductor supply chain. Chip equipment manufacturers are booking orders months in advance, and the revenue is translating directly into margin improvement.
