The company, which faces legal action in France over allegations of mistreatment of elderly residents and embezzlement of public funds, posted a net loss of 269 million euros ($260.37 million) in the first half of 2022, compared with a profit of 102 million euros in the same period last year.

"The company has been severely affected by the unethical behaviour of its former managers and by its rapid international and real estate development, which have weakened Orpea's financial situation", Chief Executive Laurent Guillot said in a statement.

Orpea said in June that an independent audit had found evidence of financial wrongdoing - including inflated labour expenses and suspicious large payments to third parties - but did not support all allegations against the company. It has denied allegations of embezzlement, tax fraud and patient mistreatment.

The company, which operates across 22 countries and is one of Europe's biggest commercial care home operators, said depreciation, amortisation and provisions amounted to 333.2 million euros in the first half of the year, up from 268.7 in the same period of 2021.

The group also confirmed that its operating profit margin in second half of the year could be lower than in the first half due to volatile energy prices, which would require Orpea to approach its creditors to renegotiate its financial covenants.
