2012 Full Year Highlights:

Fourth Quarter 2012

Worldwide revenues of $44.6 million for the fourth quarter of 2012 increased 4 percent compared to the fourth quarter of 2011. Domestic revenues of $40.1 million for the fourth quarter of 2012 grew by 6 percent compared to the fourth quarter of 2011, primarily based on the strength of the dental, spine and BGS/GO businesses and were offset by weakness in the surgical specialties and sports medicine businesses. International revenues of $4.5 million for the fourth quarter of 2012 decreased 12 percent as compared to the fourth quarter of 2011. On a constant currency basis, international revenues decreased 9 percent as compared to the fourth quarter of 2011.

For the fourth quarter of 2012, the company reported net income of $2.3 million and net income per fully diluted share of $0.04, based on 56.3 million fully diluted shares outstanding, compared to net income of $2.4 million or $0.04 per fully diluted share for the fourth quarter of 2011, based on 55.7 million fully diluted shares outstanding.

“Revenues in the fourth quarter met expectations and were driven primarily by continued growth in our dental, spine and BGS/GO businesses,” said Brian K. Hutchison, president and chief executive officer of RTI. “Overall, we are pleased with our growth for the quarter, despite the unanticipated impact on direct distribution revenue due to customer reaction to the FDA warning letter in the U.S. that was received in October 2012. International revenues were negatively impacted by inaccuracies in European media coverage about the company and the tissue industry. We continue to work through these issues and will bring them to resolution.”

Full Year 2012

Worldwide revenues of $178.1 million for the full year of 2012 were up 5 percent compared to 2011. Domestic revenues of $156.8 million for the full year of 2012 were up 6 percent compared to 2011 primarily based on the strength of the dental, BGS/GO, and sports medicine businesses. International

revenues of $21.3 million for the full year of 2012 increased 1 percent compared to 2011 primarily based on the strength of the sports medicine and BGS/GO businesses. On a constant currency basis, international revenues increased 8 percent for the full year of 2012 compared to 2011.

For the full year of 2012, the company reported net income of $8.4 million and net income per fully diluted share of $0.15, based on 56.1 million fully diluted shares outstanding, compared to a net income of $8.4 million and net income per fully diluted share of $0.15, based on 55.4 million fully diluted shares outstanding. Excluding a pre-tax litigation charge of $2.4 million, or $0.03 cents per fully diluted share, taken in the second quarter, net income per fully diluted share for the full year 2012 was $0.18.

Fiscal 2013 and First Quarter Outlook

The company expects full year revenues for 2013 to be between $178 million and $182 million. Full year net income per fully diluted share is expected to be in the range of $0.17 to $0.19, based on 56.7 million fully diluted shares outstanding. In 2013, the company will make investments in distribution, marketing and development activities to support the launch of its direct surgical specialties business and expand its presence in general orthopedics.

For the first quarter of 2013, the company expects revenues to be between $38 million and $39 million, and net income per fully diluted share to be approximately $0.02.

“Due to customer reaction to the FDA warning letter and inaccuracies in media coverage in 2012, we expect a weaker first half of the year. Following the anticipated closure of the warning letter, expansion of our direct distribution business and the launch of several new implants, we expect the second half of the year to be strong.” said Hutchison. “We also expect that the investments we are making in new products and direct distribution, combined with our active business development efforts, will accelerate our future revenue growth.”

Use of Non-GAAP Financial Measures

To supplement RTI Biologic’s condensed consolidated financial statements presented on a GAAP basis, the company discloses certain non-GAAP financial measures that exclude certain amounts, including non-GAAP net income and non-GAAP net income per fully diluted share. These non-GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States. Reconciliations of each of these non-GAAP financial measures to the corresponding GAAP measures are included in the reconciliation above.

The following is an explanation of the adjustment that management excluded as part of the non-GAAP measures for the year ended December 31, 2012 as well as the reasons for excluding the individual item:

Litigation settlement – This adjustment represents a charge and relates to a litigation settlement of certain BTS related lawsuits. Management removes the amount of the litigation settlement charge from the Company’s operating results to assist in assessing its operating performance in the current period and to supplement a comparison to the Company’s past operating performance.

Material Limitations Associated with the Use of Non-GAAP Financial Measures

Non-GAAP net income and non-GAAP net income per fully diluted share should not be considered in isolation, or as a replacement for GAAP measures.

Usefulness of Non-GAAP Financial Measures to Investors

The Company believes that presenting non-GAAP net income and non-GAAP net income per fully diluted share in addition to the related GAAP measures provide investors greater transparency to the information used by management in its financial decision-making which excludes the litigation settlement charge. The Company further believes that providing this information better enables RTI Biologic’s investors to understand the Company’s overall core performance and to evaluate the methodology used by management to assess and measure such performance.
