Comments

“We experienced mixed results in the first quarter,” stated M. Christine Jacobs, Chairman and CEO. “Brachytherapy continues to be affected by an overall decline in the number of procedures for the treatment of prostate cancer. Yet the brachytherapy business did improve slightly from fourth quarter 2012 results. Our surgical products business experienced softened demand. This trend mirrored public statements made by our larger customers regarding an overall decline in medical procedures and a reduction in visits to physicians by patients in the first quarter. Both businesses were also impacted by the new medical device tax implemented on January 1, 2013.”

Ms. Jacobs continued, “Our response to this macroeconomic environment, softening demand for medical devices and our recent operating results will be continued cost reductions, enhanced outsourcing initiatives and shoring up of demand. We expect to aggressively pursue export channels for surgical products and continue to search for opportunities to gain market share in our brachytherapy business.”

“As pertains to outsourcing and cost reductions, we are closing our vascular access manufacturing facility in Garland, Texas by the end of 2014,” Ms. Jacobs stated. “We will outsource most of this manufacturing to independent suppliers in Latin America. Some of the more complex manufacturing in this operation will be transferred to our specialty needle plant in North Attleboro, Massachusetts. Once complete, we expect this restructuring to significantly reduce our costs and allow us to remain competitive in a highly competitive marketplace. We deeply regret the loss of jobs and having to take these steps. However, we continue to be responsive to our customers’ needs and to address and anticipate macroeconomic conditions. Regulatory issues, taxes and decreased demand across the sector dictate that we change with the environment. To be clear, the Galt brand and its products will remain an integral future platform we intend to support and expand.”

Ms. Jacobs concluded, “I stated last quarter that we expected 2013 to be challenging. Our outlook has not changed. However, restructuring, outsourcing of our vascular access manufacturing and continued integration of operations are significant steps towards improving profitability for Theragenics. We plan to continue our product development efforts and to look for strategic tuck-in opportunities. Growth in the medical device industry will be a tall order in the short term but delivery of long term shareholder value remains a top priority.”

This press release contains disclosure of earnings before interest, taxes, depreciation, amortization and share-based compensation (which we refer to as “Adjusted EBITDA”). We believe Adjusted EBITDA provides an additional and meaningful assessment of our ongoing results and performance. Because we have historically reported what we currently refer to as Adjusted EBITDA, we also believe that the inclusion of this non-GAAP measure provides consistency in our financial reporting and facilitates investors' understanding of our historical operating trends by providing an additional basis for comparisons to prior periods. In addition to measures such as net income and operating income as calculated and presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”), we utilize Adjusted EBITDA, among other things, 1) to establish financial and operational goals; 2) to monitor our actual performance in relation to our business plan and operating budgets; 3) to understand key trends; 4) to make operational decisions and allocate resources; and 5) as part of several components we consider in determining incentive compensation. We believe presentation of Adjusted EBITDA provides supplemental information that is helpful to an understanding of the operating results of our businesses and period-to-period comparisons of performance. However, we recognize that the use of non-GAAP measures has limitations, including the fact that they may not be directly comparable with similar non-GAAP financial measures used by other companies. We compensate for these limitations by providing reconciliation to the most directly comparable GAAP financial measure. All non-GAAP financial measures are intended to supplement the applicable GAAP disclosures and should not be considered in isolation from, or as substitute for, financial information prepared in accordance with GAAP. For a reconciliation of non-GAAP measures from GAAP reported amounts, please refer to Table IV to this press release.

This press release contains forward looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, the accuracy of which is necessarily subject to risks and uncertainties, including, without limitation, statements regarding future growth, opportunities and investments, pipeline, and anticipated results in general. From time to time we may make other forward-looking statements relating to other matters, including without limitation, research and development plans, restructuring of our vascular access manufacturing operations, investments in our surgical products and brachytherapy businesses and capital expenditures. Actual results may differ materially due to a variety of factors, including, among other things, uncertainties related to the timing, savings, capital expenditures, expenses and other factors related to the restructuring of our vascular access manufacturing operations, the integration of acquired companies and assets into our organization, the timing and the ability to capitalize on opportunities for investment and growth within our surgical products business, ability to recognize value from areas of shared expertise, risks and uncertainties related to competition within the medical device industry, development and growth of new applications within the markets for wound closure, vascular access, specialty needle, brachytherapy and, more broadly, medical devices, competition from other companies within the wound closure, vascular access, specialty needle, brachytherapy and medical device markets, competition from other methods of treatment, new product development cycles (pipeline), effectiveness and execution of marketing and sales programs, changes in product pricing, changes in costs of materials used in production processes, changes in the ordering patterns of our customers, continued acceptance of and demand for our products by the markets in which we operate, introduction and/or availability of competitive products by others, potential changes in third-party reimbursement, including Medicare reimbursement as administered by the Centers for Medicare and Medicaid Services (CMS), implementation of new legislation by CMS, physician training, third-party distribution agreements, ability to execute on acquisition opportunities on favorable terms and successfully integrate any acquisitions, potential changes in applicable tax rates, legislative changes to healthcare markets and industries such as the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act (including provisions such as the medical device tax which took effect January 1, 2013), uncertainties related to the credit and investment markets and other factors set forth from time to time in our filings with the Securities and Exchange Commission.

All forward looking statements and cautionary statements included in this document are made as of the date hereof based on information available to us as of the date hereof, and we assume no obligation to update any forward looking statement or cautionary statement.
