The group, which trades from around 600 stores, said overall revenue was flat at 214.6 million pounds.
Thorntons said its key challenge continues to be the own stores channel, which saw a 3.6 percent fall in sales.
"We have strengthened our senior retail management team and we believe that this, together with extensive product innovation and changes to the promotional and marketing programmes, should have a positive impact on trading in the lead up to Christmas," it said.
The firm said trading since the year-end had been in line with internal expectations.
Thorntons, which cut net debt to 26 million pounds during the year, maintained its total dividend payout at 6.05 pence.
Shares in the retailer, which have lost nearly a third of their value over the last six months, closed on Tuesday at 82.5 pence, valuing the business at 56.4 million pounds.
