Nov 6 (Reuters) - Landry's Restaurants Inc (LNY.N) posted a third-quarter profit, helped partly by lower costs, and said it will restate its first- and second-quarter results to adjust for non-controlling interests in its T-Rex subsidiary.

For the third quarter, net income available to the company's common stockholders was $6.7 million, or 41 cents a share, compared with a loss of $17.1 million, $1.06 a share, a year earlier. Excluding items, it earned 2 cents a share.

Revenue from continuing operations fell 5 percent to $276.6 million.

Two analysts on average expected the company to post a loss of 18 cents a share, before items, on revenue of $264.3 million, according to Thomson Reuters I/B/E/S.

Landry's said it will amend the results of the first two quarters of 2009 as it did not properly consider the accreted value of its redeemable non-controlling interests in T-Rex in its determination of net income available to the company's common stockholders.

The restatement will have no effect on the company's cash flows or financial position, it said in a statement.

Shares of the Houston-based company were trading up 1 percent at $14.85 Friday afternoon on the New York Stock Exchange. (Reporting by Renju Jose; Editing by Pradeep Kurup)
