Triangle Capital Corp. has filed a shelf registration statement for the sale of up to $1 billion of securities from time to time.

The securities consist of common stock, preferred stock, warrants, subscription rights, debt securities and units. The $1 billion aggregate principal amount of securities under the offering includes about $143.1 million of securities registered in an October 2014 filing that remained unsold.

Triangle Capital intends to use the net proceeds from the sale for investment and general corporate purposes, including the repayment of any amounts outstanding under its credit facility. The company also plans to invest the net proceeds in lower middle market companies.
