STORY: Germany kicked off the sales process for bailed-out energy firm Uniper on Tuesday...

paving the way for what could become one of Europe's biggest deals this year.

Berlin had to nationalize Uniper during Europe's 2022 energy crisis for $15.7 billion to save it from collapse.

That was after its former main supplier of gas, Gazprom, stopped deliveries.

The government said in an official note placed in the Financial Times that suitors have until June 12th to submit a letter of intent.

Two people familiar with the matter told Reuters last month that the process could be started via an official tender note before the summer.

It's expected the process will result in an outright sale or IPO of the company, 

Under European Union requirements, Berlin must reduce its Uniper stake to a maximum of 25% plus one share by the end of 2028.
