European markets mixed, Erste Group Bank rises 8% after acquiring stake in Santander’s Polish unit

European bourses had a mixed start to the week on Monday, with U.K. markets closed for a bank holiday, as investors looked ahead to the latest economic data and corporate earnings reports due this week.

Germany’s DAX ended the session 1.1% higher and Italy’s FTSE MIB was 0.4% higher while the French CAC 40 fell 0.55%.

Santander on Monday announced that Austria’s Erste Group Bank had acquired an around 49% stake in Poland-based Santander Bank Polska and 50% of Polish asset manager Santander TFI. Shares in Erste Group closed 8.2% higher.

Amsterdam-traded shares in Shell meanwhile were 1.9% lower after Bloomberg reported the energy giant was evaluating a potential acquisition of its rival BP.

“As we have said many times before we are sharply focused on capturing the value in Shell through continuing to focus on performance, discipline and simplification,” a spokesperson for Shell said in response to CNBC’s request for comment.

French satellite company Eutelsat meanwhile soared, ending the day 15% higher, after announcing the appointment of Jean-François Fallacher, a former executive at telecommunications operator Orange, as its new CEO effective June 1.

Data released Monday showed that Swiss inflation fell to 0% in April compared to the same month a year earlier, coming in lower than expected. Turkish inflation meanwhile rose 3% in the month of April, taking the annual rate to 37.86%.

While it will be a quiet start to the week on the earnings front, several major companies are due to report in the coming days including Novo Nordisk, BMW, Maersk and Commerzbank.

Central Banks across Europe will also be in focus this week, with Sweden’s Riskbank, Norway’s Norges Bank and the Bank of England among those announcing their latest interest rate decisions.
