The company, which sells its mid-price steaks in towns across Denmark, found itself at the centre of a social media meltdown after winning a court battle against Jensen's Fish Restaurant in northern Jutland.
The court forced the restaurant to change its name, even though Jensen is the country's most common surname.
“A clear supreme court decision in favour of Jensen's Bøfhus triggered an unexpectedly lively, negative media storm that resulted in a significant reduction in the number of guests,” the company explained in its financial results statement, released on Thursday.
In the months after its court victory, the Facebook page Boykot Jensen's Bøfhus gained 100,000 likes on Facebook, with many Danes even going so far as to donate money to support the beleaguered fish restaurant, which has since changed its name to Jacob's Fish Restaurant.
In it's financial results, the company reported a loss of 30 million Danish kroner ($4.5m) for 2014, triple the shortfall it reported the previous year.
