Asda has filed accounts at the UK's Companies House showing it made annual profits of £803.5m (€927.4m) in 2010, according to the Guardian newspaper.
The Walmart-owned retailer's operating profits were £93m down on 2009 primarily because of a £137m (€158.1m) rise in royalty payments to its US parent.
Asda was also hit with an £18m (€20.8m) charge relating to stock options linked to the price of Walmart shares.
Excluding charges and royalties, underlying profits increased 4.6 per cent on the previous year to £998.6m (€1.15bn).
An Asda spokesman said: 'Overall 2010 was a good year for us.'
