Aug 17 (Reuters) - Australian winemaker Treasury Wine Estates TWE.AX said on Thursday its annual net profit rose 55 percent, boosted by growth in Asian and U.S. markets, but missed analyst forecasts.
Net profit for the year to June 30 rose to A$269.1 million ($213.3 million) from A$173.3 million a year ago, the company said, below estimates of A$288.1 million according to Thomson Reuters I/B/E/S.
The world's biggest listed stand-alone winemaker also announced an on-market share buyback of A$300 million.
Wine volumes increased almost 50 percent to Asia, which Treasury described as its "key growth engine", while U.S. markets also showed robust volume growth, the company said.
The company said its annual results were affected by unfavourable currency movements, with a rising Australian dollar hurting its revenue receipts in the Americas, which accounts for about 23 percent of revenue.
The company declared a final dividend of 13 cents per share, compared to 12 cents in the previous year.
Treasury shares rose 1.4 percent in early trade to $12.76 in a flat overall market.
