Dixons Carphone, the electricals and telecommunications retailer, posted a 30% rise in first half profit on the back of market share gains.
The newly merged company said it was on track to meet expectations for the full year.
In August, Dixons Retail and Carphone Warehouse concluded an all-share merger to create Dixons Carphone, a consumer electricals powerhouse with a place in Britain's blue chip FTSE 100 index.
Dixons Retail was Europe's second biggest consumer electronics retailer, and Carphone Warehouse was Europe's largest independent mobile phone firm.
The merged firm, which trades as Carphone Warehouse, Currys and PC World in the UK and Ireland, Elkjop and El Gigantti in Nordic countries and Kotsovolos in Greece, said it made a pro-forma pretax profit of £78m in the 31 weeks to November 1.
The group also posted a 5% rise in sales at stores open over a year. Second quarter like-for-like sales were up 9%, while gross margins were stable in the first half.
The firm made market share gains across its electrical and mobile businesses in the UK and Ireland, Nordics and Greece.
However, it said the Netherlands and Germany remained "challenging", with action underway to "review and restructure".
Dixons Carphone said its overall integration was progressing well and it now expected to deliver a minimum £80m of synergies by 2016-17, one year ahead of plan.
However, it posted a statutory loss before tax from its continuing operations of £20m after booking exceptional charges of £100m.
The firm said it would pay an interim dividend of 2.5 pence.
