Several major European companies reported first-quarter earnings results this week, with mixed performance across sectors but generally positive forward guidance updates.

German utility E.ON confirmed its full-year guidance after reporting a 7% increase in adjusted net profit compared to the same period last year. The company's results excluded exceptional and other one-off items in its earnings calculation.

Competitor RWE also posted strong results, with adjusted earnings before interest, taxes, depreciation and amortization rising 25% year-over-year. The company's adjusted earnings per share similarly increased 25%, with offshore wind operations helping to offset weaker trading performance during the quarter.

Industrial conglomerate Siemens announced a new share buyback program worth up to $7 billion over a maximum five-year period. The announcement came alongside the company's report of higher second-quarter revenue across its industrial business units.

Telecommunications provider Deutsche Telekom raised its full-year guidance despite reporting lower net profit in the first quarter. The company cited an improved outlook from its U.S. subsidiary operations as the basis for increasing its annual expectations.

In pharmaceutical and specialty chemicals sectors, Takeda Pharmaceutical reported non-GAAP earnings per share of ¥517.00 with revenue of ¥4505.7 billion, while also providing its fiscal year 2026 forecast. ICL Group beat analyst expectations with non-GAAP earnings per share of $0.11 and revenue of $2.02 billion, subsequently raising its fiscal year 2026 outlook.
