Triangle Capital Corporation to be Added to Russell 3000 Index

RALEIGH, N.C., June 16, 2009 (GLOBE NEWSWIRE) -- Triangle Capital Corporation (Nasdaq:TCAP) ("Triangle" or the "Company"), a leading specialty finance company that provides customized financing solutions to lower middle market companies located throughout the United States, announced today that the Company is set to join the broad-market Russell 3000 Index when Russell Investments reconstitutes its comprehensive set of U.S. and global equity indexes on June 26, according to a preliminary list of additions posted June 12 on www.russell.com.

Annual reconstitution of Russell's U.S. indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization. Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000(r) Index or small-cap Russell 2000(r) Index as well as the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $4 trillion in assets currently are benchmarked to them.

Total returns data for the Russell 3000 and other Russell Indexes is available at www.russell.com/Indexes/performance/default.asp.
