Gladstone Capital Reports Valuation Results for the Fourth Quarter Ended September 30,
2007 Reflecting Depreciation of $0.34 per share in Fair Value of Investment Portfolio

McLean, VA, October 10, 2007: Gladstone Capital Corp. (NASDAQ: GLAD) (the “Company”) today announced the change in fair value of its portfolio of loans for its fourth fiscal quarter ended September 30, 2007.  The Company intends to announce earnings and file its Annual Report on Form 10-K in early December 2007.

During the quarter ended September 30, 2007, the financial markets were exceedingly volatile, leading to speculation about the amount of unrealized appreciation or depreciation in the Company’s current portfolio of loans.  The Company is releasing the aggregate valuation of its loans at September 30, 2007 in order to help investors assess the impact of the recent market volatility on the Company’s portfolio. The Company does not expect to make this kind of release in the future.

During the quarter ended September 30, 2007, the aggregate valuation of the portfolio was depreciated approximately $4.89 million, or $0.34 per share (on a weighted average, fully diluted basis), representing approximately a 1.3% decline in the valuation of the Company’s portfolio from the June 30, 2007 value. The Company’s board of directors has established valuation policies and procedures under which its investment adviser, Gladstone Management Corporation (“GMC”) performs an initial assessment and forms preliminary valuation conclusions, which are then discussed with the Company’s management, and submitted to the Company’s board of directors along with opinions of value for certain of the Company’s securities submitted to the board of directors by Standard & Poor’s Loan Evaluation Services, Inc. (“SPSE”).(1)  The board of directors reviews the documentation and discusses the input of GMC, management, and the opinions of value of SPSE to arrive at a determination for the aggregate fair value of the Company’s portfolio of investments.  The Company’s board of directors accepted the aggregate valuation described above on October 9, 2007.  The Company’s valuation policies, procedures and processes are more fully described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies — Investment Valuation” in the Company’s latest Quarterly Report on Form 10-Q as filed with the U.S. Securities and Exchange Commission on August 6, 2007.

Many of the individual loan depreciations represented in the total depreciation were based in part on a reduced opinion of value given to the Company’s board of directors by SPSE.  The Company believes that SPSE’s opinion of value on these loans reflects its judgment that the market pricing for all loans had declined. In addition, most of the senior syndicated loans held by the Company that


(1) SPSE’s opinions of value reflect its best judgment of what it believes, based on comparable market prices for similar securities, the bid side of the market for each loan would be after its careful review and analysis of descriptive, market and credit information. Because of fluctuation in the market and other factors beyond its control, SPSE cannot guarantee its opinions of value.    SPSE’s opinions of value used by the Company in its valuation determinations for the quarter ended September 30, 2007 reflect the market prices, or estimates thereof, as of September 28, 2007, the last business day of the quarter ended September 30, 2007. SPSE has obtained market information from reputable secondary market sources, and although these sources are considered reliable, SPSE cannot guarantee their accuracy.




were not submitted to SPSE for opinions of value saw bids move from 100% (par) to 94% (or lower for some loans) and then rebound as the quarter ended. About 65% of the total depreciation this quarter resulted from depreciation in the Company’s senior syndicated loan portfolio. The syndicated loan debt market has continued to strengthen since the end of the quarter.

As most shareholders know, the depreciation of an investment does not reduce the net investment income of the Company and therefore does not impact the Company’s ability to pay its dividends from current income. Dividend payments are, however, impacted by whether the Company’s borrowers are making payments on the loans in the Company’s portfolio.

All but one of the loans in the Company’s portfolio were paying as agreed as of September 30, 2007 and the Company does not foresee that they will not pay in the future.  Since the Company plans to hold the loans until maturity, the Company does not currently expect to have a loss on any of the loans. The one loan that is not paying as agreed was purchased for $2.2 million (which was at a 45% discount) in connection with the Company’s previously announced purchase of a loan pool from Wells Fargo during the quarter ended June 30, 2007. The Company’s portfolio management team is working with management of the borrower and the owners of the business and hope to have that situation resolved in the near future.

“We are proud of the fact that our portfolio of loans has withstood such a traumatic change in the markets and had only a small impact of 34 cents per share,” said Chip Stelljes, President of the Company. “This is a testament to the underwriting skills and the work of our team with our borrowers.  We have been rewarded by the market’s recognition of our efforts to keep our asset quality high and our dividends safe.  We look forward to a good outcome for the quarter ending December 31, 2007.”

The valuation information that the Company has released today is subject to final review by the Company’s independent registered public accounting firm before the valuation of the portfolio is published in the Company’s Annual Report on Form 10-K that the Company expects to file and mail to shareholders in December.  The Company currently has no basis to believe that the valuation released today will materially change based on this review.
