Inter confirmed the club ran at a loss of €245.6m in 2020-21, the highest ever deficit in the history of Serie A.
Their losses more than doubled compared to the 2019-20 campaign, which ended with negative figure of €102.4m.
Because of the COVID-19 pandemic and the lack of fans in stadiums, the revenue also fell from €373.3m to just €364.7m.
However, that only tells half the story, because over the last two financial years, Inter have lost over €900m.
The Nerazzurri coffers will be bolstered for the 2021-22 financial year by the sales of Romelu Lukaku and Achraf Hakimi, but Suning continue to seek new investors, having taken loans and emitted bonds to raise funds.
The €245m losses represent the highest in history for a Serie A club, eclipsing the €209.9m losses posted by Juventus in 2020-21.
Of the top 10 biggest loss-making seasons in Serie A, six were at Inter, as they also ran at a loss of €206m in 2006-07, €181.4m in 2005-06, €154.4m in 2008-09, €148.3m in 2007-08 and €140.5m in 2014-15.
