FRANKFURT/DUESSELDORF—Soon-to-be-nationalized gas importer Uniper reported a record 40 billion euro ($39.3 billion) net loss in the first nine months of this year, the biggest in German corporate history, after Russia stopped its supplies.
The loss further highlights how Russia’s decision to sever a decade-long supply relationship with Europe, most notably Germany, is impacting the continent’s energy sector, with Uniper the crisis’ biggest corporate casualty so far.
