Coca-Cola Co says its second-quarter net income rose 18 per cent as it sold more drinks around the world, especially its namesake brand.

The world’s largest beverage maker earned $US2.8 billion ($A2.65 billion), or $US1.20 per share, for the three months ended July 1.

That’s up from $US2.37 billion ($A2.24 billion), or $US1.02 per share, in the same quarter last year.

Revenue climbed 47 per cent to $US12.74 billion ($A12.05 billion) from $US8.67 billion ($A8.2 billion), partly because of Coke’s acquisition of its largest North American bottler.

The results beat analysts’ forecasts for earnings of $US1.15 per share on revenue of $US12.39 billion ($A11.72 billion).

The Atlanta company said on Tuesday that it sold 4 per cent more of its Coca-Cola brand drinks globally.

Coca-Cola has seen consistent growth for years because of steady sales in established markets and faster increases in emerging markets.
