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

ALACHUA, Fla. (August 6, 2013) – RTI Surgical Inc. (RTI) (Nasdaq: RTIX), a leading global surgical implant company, reported operating results for the second quarter of 2013 as follows:

Quarterly Highlights:

Worldwide revenues of $42.3 million for the second quarter of 2013 decreased 6 percent compared to the second quarter of 2012. Domestic revenues of $37.4 million for the second quarter of 2013 decreased 5 percent compared to the second quarter of 2012, primarily due to weakness in the sports medicine, surgical specialties and bone grafts substitutes and general orthopedic businesses, offset by strength in the spine business. International revenues of $4.9 million for the second quarter of 2013

decreased 18 percent as compared to the second quarter of 2012. On a constant currency basis, international revenues for the second quarter of 2013 decreased 20 percent as compared to the second quarter of 2012.

For the second quarter of 2013, the company reported net loss of $3.0 million and net loss per fully diluted share of $0.05, based on 56.3 million fully diluted shares outstanding, compared to net income of $1.3 million or $0.02 per fully diluted share for the second quarter of 2012, based on 56 million fully diluted shares outstanding.

In 2005, the company was named as a party, along with a number of other recovery and processor defendants in lawsuits relating to the tissue recovery practices of BTS, an unaffiliated recovery agency. During the second quarter of 2012, the company accrued a pre-tax litigation settlement charge of $2.35 million, or $0.03 per fully diluted share to settle certain cases related to these proceedings. During the second quarter of 2013, the company accrued a pre-tax litigation settlement charge of $3 million, or $0.03 cents per fully diluted share to settle substantially all of the remaining lawsuits relating to these proceedings. This brings to conclusion any material risk related to BTS.

Also during the second quarter of 2013, the company accrued a pre-tax expense of $1.5 million for certain fees related to the acquisition of Pioneer.

Excluding the litigation settlement charge of $3 million and the expense related to the acquisition of Pioneer of $1.5 million, the company reported net income of $0.00 per fully diluted share.

“While second quarter revenues were in line with our expectations, net income fell short,” said Brian K. Hutchison, president and chief executive officer of RTI. “The shortfall in net income for the period was due to the $3 million BTS litigation settlement charge, the $1.5 million expense related to the acquisition of Pioneer, as well as lower gross margins primarily related to the mix of implants distributed and the continued investment in the business to launch our new surgical specialties distribution force.”

Fiscal 2013 and Third Quarter Outlook

Based on the acquisition of Pioneer and results from the first six months the company is revising its full year revenue guidance for 2013. The company now expects full year revenue guidance for 2013 to be between $211 million to $215 million, as compared to prior guidance of $179 million to $182 million.

Full year net loss after preferred dividends per fully diluted share applicable to common shareholders is expected to be in the range of $0.13 to $0.11, based on 56.7 million fully diluted shares outstanding, as compared to prior guidance of full year net income per fully diluted share applicable to common shareholders of $0.17 to $0.19. Excluding certain acquisition related expenses, certain purchase accounting adjustments, and the BTS litigation settlement charge taken in the second quarter, full year net income after preferred dividends per fully diluted share applicable to common shareholders is expected to be in the range of $0.05 to $0.07. Throughout the remainder 2013, the company will continue to integrate the Pioneer business, make investments in distribution, marketing and development activities to support the launch of new products and to expand its presence in general orthopedics.

For the third quarter of 2013, the company expects revenues to be between $59 million and $61 million and net loss after preferred dividends per fully diluted share applicable to common shareholders to be approximately $0.10, based on 56.8 million fully diluted shares outstanding. Excluding certain acquisition related expenses and certain purchase accounting adjustments, third quarter net income after preferred dividends is expected to be approximately $0.00 per fully diluted share applicable to common shareholders.

Use of Non-GAAP Financial Measures

To supplement RTI Surgical’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 (loss) income and non-GAAP net (loss) 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 are explanations of the adjustments that management excluded as part of the non-GAAP measures for the three and six month period ended June 30, 2013 as well as the reasons for excluding the individual item:

2013 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 year-to-date period and to supplement a comparison to the Company’s past operating performance.

2013 Acquisition expenses – This adjustment represents a charge and relates to certain fees associated with the acquisition of Pioneer. Management removes the amount of these one-time fees from the Company’s operating results to assist in assessing its operating performance in the year-to-date period and to supplement a comparison to the Company’s past operating performance.

2012 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 prior year periods to supplement a comparison to the Company’s current 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 Surgical’s investors to understand the Company’s overall core performance and to evaluate the methodology used by management to assess and measure such performance.
