Exhibit 99.1

XENITH BANKSHARES, INC. RECEIVES $8.4 MILLION OF

CAPITAL FROM U.S. TREASURY’S

SMALL BUSINESS LENDING FUND

RICHMOND, VA, September 21, 2011 – Xenith Bankshares, Inc. (NASDAQ:XBKS), parent company of Xenith Bank, today announced that it has received a capital investment of $8,381,000 from the United States Department of the Treasury under the Small Business Lending Fund (SBLF). The company issued shares of a newly-authorized class of preferred stock, designed as Senior Non-Cumulative Perpetual Preferred Stock, Series A, to the U.S. Treasury in exchange for the capital investment. The SBLF is a $30 billion voluntary program established under the Small Business Jobs Act of 2010 created to encourage lending to small businesses by providing capital to qualified banks at favorable dividend rates.

“We are very pleased to have been selected by the U.S. Treasury to participate in the SBLF,” said T. Gaylon Layfield, III, President and Chief Executive Officer. “The additional capital will continue to facilitate Xenith’s lending to businesses in our target markets.”

The SBLF preferred stock investment qualifies as Tier 1 capital. The SBLF preferred stock is entitled to receive non-cumulative dividends, payable quarterly, beginning October 1, 2011. The dividend rate, as a percentage of the liquidation amount, can fluctuate on a quarterly basis during the first 10 quarters during which the SBLF preferred stock is outstanding, based upon changes in the level of Xenith’s “Qualified Small Business Lending” (QSBL). The initial dividend rate through September 30, 2011 is 1% per annum. For the second through ninth calendar quarters after issuance, the dividend rate may be adjusted to between 1% per annum and 5% per annum to reflect changes to Xenith’s QSBL. If the level of Xenith’s qualified small business loans declines so that the percentage increase in QSBL as compared to the baseline level of QSBL is less than 10%, then the dividend rate payable on the SBLF preferred stock will increase. For the tenth calendar quarter through four and one half years after issuance, the dividend rate will be fixed at between 1% and 7% based upon the increase in QSBL as of the ninth calendar quarter as compared to the baseline. After four and one half years from issuance, the dividend rate will increase to 9% per annum until the SBLF funding is repaid in full. The company may, at its option, redeem the SBLF preferred stock in whole or in part at any time, subject to bank regulatory approval.

The securities have not been registered under the Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws. This press release shall not constitute an offer to sell or the solicitation of an offer to buy any of the securities.
