Segment Results

Surgical Products Segment

Revenue in our surgical products segment was $14.3 million in fourth quarter 2011, a decrease of 5% from fourth quarter of 2010. For the year revenue was $59.4 million, an increase of 1% over 2010. Our surgical products segment incurred a loss from operations of $480,000 in the fourth quarter of 2011 compared to operating income of $63,000 in the fourth quarter of 2010. Pre-tax charges for special items totaled $305,000 in the fourth quarter of 2010. There were no special charges in the fourth quarter of 2011. For the full year, operating income was $607,000 compared to $215,000 in 2010. Pre-tax charges for special items totaled $218,000 in 2011 and $1.6 million in 2010. Pre-tax charges for special items are detailed in Table V to this press release.

“Our surgical products business experienced headwinds in the fourth quarter. Those headwinds were both customer and operational specific. Customer erratic ordering patterns vary and have been mentioned throughout the year but were magnified in the fourth quarter. ERP implementation also affected one of our business units in the fourth quarter,” stated M. Christine Jacobs, Chairman and CEO. “Underlying demand in our surgical products segment remains strong and we believe fourth quarter does not portend a systemic slowdown of momentum. Indeed, our open orders at the end of 2011 were 7% higher than at the end of 2010.”

Brachytherapy Seed Segment

Revenue in our brachytherapy segment was $5.8 million in fourth quarter of 2011, a 1% increase over fourth quarter of 2010 and $24.1 million for the year, a 1% increase over 2010. Operating income was $1.1 million for the quarter compared to $439,000 in 2010. There were no special items for the fourth quarter of 2011. Pre-tax charges for special items totaled $848,000 in the fourth quarter of 2010. For the full year, operating income was $4.9 million compared to $3.7 million in 2010. Pre-tax charges for special items totaled $304,000 in 2011 and $1.6 million in 2010. Pre-tax charges for special items are detailed in Table V to this press release.

“2011 was the first time in six years we experienced year over year revenue growth in brachytherapy for a full calendar year,” Jacobs said. “We are hopeful that brachy sales have reached a nadir. Our strategy of alliances and distributors continues to contribute to revenue. Of late, new data and press associated with this valuable treatment have accented this cost effective cure. We believe additional opportunities in the segment remain.”

Acquisition of Core Prostate Brachytherapy Customers

On February 17, 2012, the Company acquired the prostate brachytherapy customer base of Core Oncology. This transaction is expected to substantially increase the Company’s share of the iodine-125 segment of the brachy market and to add approximately $5 to $6 million of incremental revenue to the Company’s brachytherapy segment for the remaining portion of calendar 2012. For 2011, total brachytherapy segment revenue was $24.1 million. This asset acquisition is also expected to be accretive to earnings and generate positive cash flow from operations in 2012.

“The Core transaction and additional iodine business demonstrates our continuing commitment to this treatment, the physicians and the patients who depend on it,” said Jacobs. “Theragenics is a leading manufacturer and provider in the prostate brachytherapy market. Our legacy is improving lives and curing cancer. This transaction enhances the mission and expands our reach.”

Conclusion

Ms. Jacobs concluded, “While our surgical product revenue growth was soft in 2011, we experienced our fifth consecutive year of organic growth in that business. We did so during the past three years in an economic recession with significant macroeconomic uncertainty. Our brachytherapy business continues to deliver healthy profits and cash flows. We believe our brachy business turned a corner with our first calendar year of revenue growth since 2005 and now the Core transaction provides momentum for 2012. We plan to continue to focus on increasing profitability, streamlining operations and continuing growth in both business segments. 2011 was our seventh consecutive year of record revenue.”

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 historic 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 to, 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 a 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.

From time to time we may make other forward-looking statements relating to other matters, including without limitation, research and development plans, investments in our surgical products and brachytherapy businesses, investments in information technology systems and expectations for new distributors.
