Dixons Carphone, the European electrical goods and mobile phone retailer formed through a merger last year, beat forecasts with a 21% rise in yearly profit and said its integration was progressing well.
The group trades as Carphone Warehouse, Currys and PC World in the UK and Ireland, Elkjop and El Giganten in Nordic countries and Kotsovolos in Greece.
It said it made an underlying pretax profit of £381m in the year to May 2, helped by market share gains from rivals and stable gross margins.
That compared with analysts' average forecast of £376m and with £316 in the 2013-14 year on a pro forma basis.
Group revenue for the year rose 6% to £9.9 billion.
The firm said it expected to deliver at least £80m of synergy benefits by the 2016-17 financial year, a year ahead of plan.
Though investors initially reacted coolly to the plan to merge Dixons Retail and Carphone Warehouse they were quickly won over and the merged group's share price has risen by nearly half since the deal was completed almost a year a go.
Dixons Carphone has benefited from cheaper prices, customer service initiatives such as free warranties and improved free delivery options, as well as growing demand for smart technology.
In the UK it has also been boosted by the demise of rival mobile phone retailer Phones4U, which collapsed into administration last September.
The firm said although Kotsovolos returned to profit during the year it was very mindful of the uncertain economic and political situation in the country and the effect this may have on a business, which contributes 2.5% of group sales.
It said the team in Greece have been very active in planning for every contingency.
Dixons Carphone is paying a total dividend of 8.5 pence, up 42%.
