TRIANGLE CAPITAL CORPORATION REPORTS SECOND QUARTER 2012 RESULTS

RALEIGH, NC – August 1, 2012, Triangle Capital Corporation (NYSE: TCAP) (“Triangle” or the “Company”), a leading provider of capital to lower middle market companies located throughout the United States, today announced its financial results for the second quarter of 2012.

Highlights

In commenting on the Company’s results, Garland S. Tucker, III, President and Chief Executive Officer, stated, “The second quarter of 2012 yielded very positive results for Triangle. Our portfolio produced realized gains during the quarter, and overall credit quality remains strong. Our efficiency ratio continues to be one of the best in the BDC industry, and we were very pleased in June to announce a 13.6% year over year increase to our quarterly dividend. Finally, our investment pace during the second quarter remained steady with seven new investments.

Taking all of these factors into account, I believe Triangle is very well positioned as we move into the second half of 2012.”

Second Quarter 2012 Results

Total investment income during the second quarter of 2012 was $22.0 million, compared to total investment income of $16.4 million for the second quarter of 2011, representing an increase of 33.8%.

Commenting on the Company’s liquidity position, Steven C. Lilly, Chief Financial Officer, stated, “We entered the second quarter in a very strong liquidity position which enabled us to fund net investments of approximately $58 million during the quarter. Our current cash on hand, combined with $75 million of availability under our existing senior credit facility, coupled with the possibility that we might expand our senior credit facility later this year, position us well to continue executing our business strategy.”

The Company has a three-year senior secured credit facility (the “Credit Facility”) with a commitment of $75.0 million, and an accordion feature which allows for an increase in the total loan size up to $90.0 million. As of June 30, 2012, the Company had no outstanding debt under the Credit Facility.

Dividend and Distribution Information

On May 30, 2012, Triangle announced that its board of directors had declared a cash dividend of $0.50 per share, representing a 13.6% year over year increase over the Company’s second quarter 2011 dividend. This was the Company’s twenty-second consecutive quarterly dividend since its initial public offering in February, 2007, and was the Company’s twelfth dividend increase. The dividend was payable as follows:

Record Date: June 13, 2012

Payment Date: June 27, 2012

At the time of its IPO in February, 2007, Triangle adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of dividends on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, when the Company declares a cash dividend, stockholders who have not opted out of the DRIP will have their cash dividends automatically reinvested in additional shares of the Company’s common stock, rather than receiving cash dividends.

When the Company declares and pays dividends, it determines the allocation of the distribution between current income, accumulated income and return of capital on the basis of accounting principles generally accepted in the United States (“GAAP”). At each year end, the Company is required for tax purposes to determine the dividend allocation based on tax accounting principles. Due to differences between GAAP and tax accounting principles, the portion of each dividend distribution that is ordinary income, capital gain or return of capital may differ for GAAP and tax purposes.

Recent Portfolio Activity

During the second quarter of 2012, Triangle made seven new investments totaling approximately $112.5 million, two debt investments in existing portfolio companies totaling approximately $1.8 million, and one equity investment in an existing portfolio company of approximately $0.3 million. During the second quarter of 2012, the Company received five loan repayments at par totaling approximately $52.1 million and received normal principal repayments and partial loan prepayments totaling approximately $4.9 million.
