NEW YORK Dec 10 (Reuters) - Specialty finance company Ellington Financial LLC pulled its initial public offering on Thursday due to market conditions, according to an underwriter.

Ellington had hoped to sell 7.7 million shares and had expected them to price between $25 and $27, a piece. The company said in a filing with the U.S. Securities and Exchange Commission that it would use the proceeds for acquisitions.

Ellington Financial had $10.1 million in net investment income in the nine months ended Sept 30, 2009, up 5.1 percent from a year ago. The company reported a net increase in shareholders' equity from operations of $80.5 million, up 523.4 percent from a year ago.

The offering was being led by Credit Suisse and Deutsche Bank. They had the option to buy an additional 1.155 million shares. (Reporting by Clare Baldwin; editing by Carol Bishopric)
