Segment Results

Surgical Products Segment

Revenue in our surgical products segment was $15.5 million in first quarter 2012, an increase of 8% over first quarter of 2011 and our highest quarterly revenue ever in our surgical products segment. Operating income was $199,000 compared to a loss of $191,000 in 2011. First quarter 2011 included pre-tax charges for special items totaling $183,000 (detailed in Table V). There were no special items in first quarter of 2012. Gross profit margins on sales were 35% in first quarter of 2012 compared to 34% in first quarter of 2011.

“Healthy revenue results and the profit turnaround contributed to a robust beginning to 2012,” stated M. Christine Jacobs, Chairman and CEO. “Orders are strong in this segment and some of the fourth quarter headwinds are behind us.”

Brachytherapy Seed Segment

Revenue in our brachytherapy segment was $6.3 million in first quarter 2012, an increase of 6% over first quarter of 2011. Operating income was $1.4 million, an increase of 28% over first quarter of 2011. First quarter 2011 included pre-tax charges for special items totaling $291,000 (detailed in Table V). There were no special items in first quarter of 2012. The customers acquired in the Core transaction (closed on February 17, 2012) added $586,000 of incremental revenue in the first quarter of 2012 and the acquisition was accretive to operating income and operating cash flow.

“The acquisition of the Core customers in February 2012 has delivered just what we expected – incremental revenue and positive operating cash flow,” said Ms. Jacobs. “While the industry continues to experience softness, this transaction and the launch of our new iodine seed will continue to enhance our position as a market leader.”

Conclusion

Ms. Jacobs concluded, “In the first quarter we delivered revenue growth in both business segments and net earnings more than doubled. Cash flow from operations was strong and our balance sheet remains solid. To be sure, headwinds remain: macroeconomic uncertainties, unpredictable customer behavior, the looming medical device tax, and CMS reimbursement policies, to name a few. Yet our prospects are brighter than last year. To date 2012 fundamental demand remains strong in our Surgical Products business, and our Brachytherapy business continues to deliver solid results. 2012 is off to a good start.”

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, 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 and capital expenditures. Actual results may differ materially due to a variety of factors, including, among other things, uncertainties related to 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, 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), 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.
