RTI BIOLOGICS ANNOUNCES 2011 SECOND QUARTER RESULTS

– Company Will Hold Conference Call at 8:30 a.m. ET –

ALACHUA, Fla. (July 28, 2011) –RTI Biologics Inc. (RTI) (Nasdaq: RTIX), a leading provider of orthopedic and other biologic implants, reported operating results for the second quarter of 2011 as follows:

Quarterly Highlights:

• Achieved quarterly revenues of $43.5 million.

• Achieved quarterly net income of $2.0 million, or $0.04 per fully diluted share.

• Achieved quarterly revenues of $12.1 million in the sports medicine business, a 5 percent increase over the second quarter of 2010.

• Achieved quarterly revenues of $7.2 million in the surgical specialties business, a 21 percent increase over the second quarter of 2010.

• Achieved quarterly revenues of $12.9 million in the U.S. direct distribution organization, an 11 percent increase over the second quarter of 2010. The U.S. direct distribution organization includes sports medicine and some BGS/GO implants.

• Launched BioAdapt™ DBM Foam, a flexible demineralized bone matrix (DBM) solution.

• Released two new spinal constructs and one bone graft substitute (BGS) for distribution with three different commercial distributors.

“We are pleased with our second quarter results, which exceeded our expectations and were driven primarily by continued growth in our surgical specialties and direct sports medicine businesses,” said Brian K. Hutchison, chief executive officer of RTI. “Revenues in the spine business were up slightly on

a sequential quarter basis; however, it remains too early to determine if market pressures are abating. The decrease in reported dental revenues is the result of the change in the terms of our distributor agreement, which was announced in the third quarter of 2010. If the new terms with our distributor had been effective in the second quarter of 2010, dental revenues would have increased by 22 percent.”

Worldwide revenues of $43.5 million for the second quarter of 2011 increased 6 percent compared to the second quarter of 2010. Domestic revenues of $38.0 million for the second quarter of 2011 grew by 5 percent as we recognized increases in spine, surgical specialties and the direct sports medicine businesses. The domestic spine and surgical specialties businesses both benefited from a favorable quarterly comparison as a result of inventory reductions made by several of our distributors in the second quarter of 2010. International revenues of $5.5 million increased 11 percent due to a favorable foreign exchange rate in the quarter. On a constant currency basis, international revenues were comparable to the second quarter of 2010.

For the second quarter of 2011, the company reported net income of $2.0 million and net income per fully diluted share of $0.04, based on 55.3 million fully diluted shares outstanding, compared to net income of $948,000 or $0.02 per fully diluted share for the second quarter of 2010, based on 55.1 million fully diluted shares outstanding.

Fiscal 2011 and Third Quarter Outlook

As a result of first half results that exceeded expectations and better visibility into second half trends, the company is raising its full year revenue and EPS guidance for 2011. The company now expects full year revenues for 2011 to be between $164 million to $166 million, as compared to prior guidance of $159 million to $162 million. Full year net income per fully diluted share are now expected to be in the range of $0.12 to $0.14, based on 55.4 million shares outstanding, as compared to prior guidance of $0.11 to $0.13 per fully diluted share.

For the third quarter of 2011, the company expects revenues to be between $40 million to $41 million, and net income per fully diluted share to be approximately $0.03.

“We had a solid first half of the year and made progress in many key areas,” Hutchison said. “We are raising our annual guidance based on stronger than expected first half results and the expectation of continued momentum within our direct business.”

RTI will host a conference call and simultaneous audio webcast to discuss the second quarter results at 8:30 a.m. ET today. The conference call can be accessed by dialing (877) 383-7419.
