On November 16, 2011, Trailer Bridge, Inc., a Delaware corporation (the “Company”), filed a voluntary petition in the United States Bankruptcy Court for the Middle District of Florida seeking relief under the provisions of Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”). The Company’s case has been assigned the following case number, Case No. 3:11-bk-08348, by the Bankruptcy Court.

The Company continues to operate its business as a debtor-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and the orders of the Bankruptcy Court.

Forward-Looking Statements

This press release contains statements that constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. The matters discussed in this press release include statements regarding the intent, belief or current expectations of the Company, its directors or its officers with respect to the future operating performance of the Company and its asset utilization. Investors are cautioned that any such forward looking statements are not guarantees of future performance and involve risks and uncertainties, and that actual results may differ materially from those in the forward looking statements as a result of various factors. Without limitation, these risks and uncertainties include: (i) the potential adverse impact of the bankruptcy case on our business, financial condition or results of operations, including our ability to maintain contracts and other customer and vendor relationships that are critical to our business and the actions and decisions of our creditors and other third parties with interests in our bankruptcy case; (ii) our ability to maintain adequate liquidity to fund our operations during the bankruptcy case and to fund a plan of reorganization and thereafter, including maintaining normal terms with our vendors and service providers during the bankruptcy case and complying with the covenants and other terms of our financing agreements; (iii) our ability to obtain court approval with respect to motions in the bankruptcy case prosecuted from time to time and to develop, prosecute, confirm and consummate a plan of reorganization with respect to the bankruptcy case and to consummate all of the transactions contemplated by such plan of reorganization; (iv) risks associated with third parties seeking and obtaining court approval to terminate or shorten the exclusivity period for the Company to propose and confirm a plan of reorganization, for the appointment of a Chapter 11 trustee or to convert the Chapter 11 bankruptcy case to a Chapter 7 case; and (v) those factors identified in our filings with the Securities and Exchange Commission as may be accessed at www.sec.gov.

The risks and uncertainties and the terms of any reorganization plan ultimately confirmed can affect the value of our various pre-petition liabilities, common stock and/or other securities. No assurance can be given as to what values, if any, will be ascribed in the bankruptcy proceedings to each of these constituencies. A plan of reorganization could result in holders of our liabilities and/or securities receiving no value for their interests. Because of such possibilities, the value of these liabilities and/or securities is highly speculative and will pose substantial risks. Trading prices for the Company’s common stock may bear little or no relationship to the actual recovery, if any, by holders thereof in the bankruptcy case. Accordingly, the Company urges extreme caution with respect to existing and future investments in its common stock. Caution should be taken not to place undue reliance on our forward-looking statements, which represent our view only as of the date of this press release, and which we assume no obligation to update.
