2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring accruals, which the Company considers necessary for a fair presentation of the results of operations for the periods shown. The condensed consolidated financial statements have been prepared in accordance with the instructions to Form10-Q and Rule10-01 of RegulationS-X, and, therefore, do not include all information and footnotes necessary for a fair presentation of consolidated financial position, results of operations, comprehensive loss and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany balances and transactions have been eliminated in consolidation. The results of operations for any interim period are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form10-K for the year ended December 31, 2017.

The condensed consolidated financial statements include the accounts of RTI Surgical, Inc. and its wholly owned subsidiaries, Pioneer Surgical Technology, Inc. (“Pioneer”), Tutogen Medical, Inc. (“TMI”), Zyga Technology, Inc. (“Zyga”), RTI Surgical, Inc. – Cardiovascular (inactive), Biological Recovery Group, Inc. (inactive) and RTI Services, Inc. (inactive). The condensed consolidated financial statements also include the accounts of RTI Donor Services, Inc. (“RTIDS”), which is a controlled entity.

3. Recently Issued Accounting Standards

Compensation—Stock Compensation— In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASU”)2017-09,“Compensation—Stock Compensation” (Topic 718): Scope of Modification Accounting. The requirement provides guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. For public business entities, this ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. The Company adopted ASU2017-09 on January 1, 2018 and it did not have an impact on its condensed consolidated financial statements.

Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets— In February 2017, the FASB issued ASU2017-05,“Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets” (Subtopic610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. This ASU requires all entities to derecognize a business or nonprofit activity in accordance with Topic 810, and requires that all entities derecognize an equity method investment in accordance with Topic 860. The amendments in this ASU eliminate the scope exceptions, and simplifies GAAP. This ASU is effective for fiscal years beginning after December 15, 2017, including interim reporting periods within that reporting period. Public entities may apply the guidance earlier but only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company adopted ASU2017-05 on January 1, 2018 and it did not have an impact on its condensed consolidated financial statements.

Business Combinations – Clarifying the Definition of a Business— In January 2017, FASB issued ASUNo. 2017-01, “Business Combinations – Clarifying the Definition of a Business” (Topic 805) (“ASUNo. 2017-01”). ASU2017-01 provides a framework to use in determining when a set of assets and activities is a business. ASU2017-01 provides more consistency in applying the business combination guidance, reduces the costs of application, and makes the definition of a business more operable. ASU2017-01 is effective for interim and annual periods within those annual periods beginning after December 15, 2017. The Company adopted ASU2017-01 on January 1, 2018 and it did not have an impact on its condensed consolidated financial statements.

5

Revenue from Contracts with Customers— On January 1, 2018, the Company adopted a new accounting standard issued by the FASB on revenue recognition using the modified retrospective method. This new accounting standard outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers. This standard supersedes existing revenue recognition requirements and eliminates most industry-specific guidance from GAAP. The core principle of the new accounting standard is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the adoption of this new accounting standard resulted in increased disclosure, including qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new accounting standard was applied to all contracts, apart from contracts for which all or substantially all revenue was recognized before January 1, 2018. Additionally, the Company elected to account for shipping and handling activities as a fulfillment cost rather than a separate performance obligation.

Adoption Impact

The Company identified three contracts which previously resulted in revenue recognition occurring at the time of shipment; however, under the new revenue recognition standard, the Company is required to recognize revenue over time. The assessment of our January 1, 2018, condensed consolidated balance sheet under ASC Topic 606 resulted in a cumulative-effect adjustment to opening retained earnings, unbilled accounts receivable and costs incurred for inventory.

The effects of the adoption under ASC Topic 606 are outlined in the following table:

	Year Ended December 31, 2017			Impact			January 1, 2018
Accounts receivable	$	35,081		$	4,014		$	39,095
Inventories - net		111,927			(1,766	)		110,161
Accrued expenses		—			1,110			1,110
Deferred tax assets		9,575			(266	)		9,309
Accumulated deficit		(237,066	)		872			(236,194	)

The impact of adoption of Topic 606 to the Company’s condensed consolidated statements of comprehensive loss for the three and six months ended June 30, 2018 was as follows:

	For the Three Months Ended June 30, 2018						For the Six Months Ended June 30, 2018
				Excluding Impact						Excluding Impact
	As Reported			of Topic 606			As Reported			of Topic 606
Total revenues	$	70,685		$	69,777		$	140,575		$	138,348
Cost of processing and distribution		40,645			40,331			76,853			75,896

Net loss		(6,441	)		(6,848	)		(8,372	)		(9,243	)

Disaggregation of revenue

The Company operates in one reportable segment composed of four lines of business. Effective January 1, 2018, the reporting of the Company’s lines of business are composed primarily of four categories: spine; sports; original equipment

6

manufacturer (“OEM”) and international. The following table presents revenues from these four categories for the three and six months ended June 30, 2018:

	For the Three Months Ended June 30, 2018		For the Six Months Ended June 30, 2018
Revenues:
Spine	$	18,934	$	38,197
Sports		14,190		27,625
OEM		31,170		61,290
International		6,391		13,463
Total revenues from contracts with customers	$	70,685	$	140,575

The following table presents revenues recognized at a point in time and over time for the three and six months ended June 30, 2018:

	For the Three Months Ended June 30, 2018		For the Six Months Ended June 30, 2018
Revenue recognized at a point in time	$	61,534	$	121,697
Revenue recognized over time		9,151		18,878
Total revenues from contracts with customers	$	70,685	$	140,575

Performance Obligations

The Company’s performance obligations consist mainly of transferring control of implants identified in the contracts.

Some of the Company’s contracts offer assurance-type warranties in connection with the sale of a product to a customer. Assurance-type warranties provide a customer with assurance that the related product will function as the parties intended because it complies with agreed-upon specifications. Such warranties do not represent a separate performance obligation and are not material to the condensed consolidated financial statements.

When Performance Obligations Are Satisfied

The Company typically transfers control at a point in time upon shipment or delivery of the implants for direct sales, or upon implantation for sales of consigned inventory. The customer is able to direct the use of, and obtain substantially all of the benefits from, the implant at the time the implant is shipped, delivered, or implanted, respectively based on the terms of the contract.

For performance obligations related to the aforementioned three contracts with exclusively built inventory clauses, the Company typically satisfies its performance obligations evenly over the contract term as inventory is built. Such exclusively manufactured inventory has no alternative use and the Company has an enforceable right to payment for performance to date. The Company uses the input method to measure the manufacturing activities completed to date, which depicts the progress of the Company’s performance obligation of transferring control of exclusively built inventory.

For the contracts with upfront and annual exclusivity fees, revenue related to those fees is recognized over the contract term following a consistent method of measuring progress towards satisfaction of the performance obligation. The Company uses the method and measure of progress that best depicts the transfer of control to the customer of the goods or services to date relative to the remaining goods or services promised under the contract.

Significant Payment Terms

The contract with the customer states the final terms of the sale, including the description, quantity, and price of each implant distributed. Payment for OEM contracts is typically due in full within 30 days of delivery or the start of the contract term. For the remaining lines of business, payment terms are typically due in full within 30 to 60 days of delivery. The Company performs a review of each specific customer’s credit worthiness and ability to pay prior to acceptance as a customer. Further, the Company performs periodic reviews of its customers’ creditworthiness prospectively. Since the customer agrees to a stated price in the contract that does not vary over the contract, the majority of contracts do not contain variable consideration.

Nature of Goods and Services

The Company distributes biologic, metal and synthetic implants. In some instances, the Company also enters into contracts with customers for exclusively manufactured inventory based on customer specifications.

7

Returns

In the normal course of business, the Company does accept product returns. The amount of consideration the Company ultimately receives varies depending upon the return terms that the Company may offer, which are accounted for as variable consideration when estimating the amount of revenue to recognize. The Company establishes provisions for estimated returns based on historical experience. The amount recorded on the Company’s balance sheets for product return allowance was $1,190 million and $1,110 million at June 30, 2018 and December 31, 2017, respectively. Liabilities for return allowances are included in “Accrued expenses”. Actual product returns have not differed materially from estimated amounts reserved in the accompanying condensed financial statements.

Critical Accounting Estimates

Estimates are used to determine the amount of variable consideration in contracts, and the measure of progress for contracts where revenue is recognized over time. The Company reviews and updates these estimates regularly. Our contracts generally do not include multiple performance obligations, and accordingly do not generally require estimates of the standalone selling price for each performance obligation.

Some contracts with customers include variable consideration primarily related to volume rebates. The Company estimates variable consideration at the most likely amount to determine the total consideration which the Company expects to be entitled. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available.

Contract Asset and Liability

The opening and closing balances of the Company’s accounts receivable, contract asset and current and long-term contract liability are as follows:

	Accounts Receivable		Contract Liability (Current)		Contract Liability (Long- Term)
Opening 1/1/2018	$	39,095	$	5,978	$	3,741
Closing 6/30/2018		45,576		6,210		3,155
Increase/(decrease)		6,481		232		(586	)

Contract liabilities consist primarily of the return allowance described above, and of deferred revenue arising from upfront and annual exclusivity fees. The difference between the opening and closing balances of the Company’s contract liabilities primarily results from the Company’s performance of the Company’s contractual obligations over time. The Company recognizes sales commissions as incurred because the amortization period is less than one year. The Company does not incur other incremental costs relating to obtaining a contract with a customer, and therefore, does not have material contract assets, or impairment losses associated therewith. Revenue recognized for the six months ended June 30, 2018 from amounts included in contract liabilities at the beginning of the period was $2,434.

4. Acquisition of Zyga Technology, Inc.

On January 4, 2018, the Company acquired Zyga Technology, Inc. (“Zyga”), a leading spine-focused medical device company that develops and produces innovative minimally invasive devices to treat underserved conditions of the lumbar spine. Zyga’s primary product is the SImmetry^® Sacroiliac Joint Fusion System. Under the terms of the merger agreement dated January 4, 2018, the Company acquired Zyga for $21,000 in consideration paid at closing (consisting of borrowings of $18,000 on our revolving credit facility and $3,000 cash on hand), $1,000 contingent upon the successful achievement of a clinical milestone, and a revenue based earnout consideration of up to $35,000. Based on a probability weighted model, the Company estimates a contingent liability related to the clinical milestone and revenue based earnout of $3,700. Acquisition related costs were approximately $1,430, of which approximately $800 was incurred during 2018 and is reflected separately in the accompanying Condensed Consolidated Statements of Comprehensive Loss.

8

The Company has accounted for the acquisition of Zyga under ASC 805,Business Combinations. Zyga’s results of operations are included in the condensed consolidated financial statements for periods ending after January 4, 2018, the acquisition date.

The purchase price was financed as follows:

	(In thousands)
Cash proceeds from revolving credit facility	$	18,000
Cash from RTI Surgical		3,000
Total purchase price	$	21,000

The valuation of the acquired assets and liabilities is not yet complete, and as such, the Company has not yet finalized its allocation of the purchase price for the acquisition. The table below represents an allocation of the total consideration to Zyga’s tangible and intangible assets and liabilities based on management’s preliminary estimate of their respective fair values as of January 4, 2018. During the three months ended June 30, 2018, the Company made the following changes to the preliminary fair values of acquired assets and liabilities: increased inventory by $500, decreased deferred tax assets by $150, decreased current liabilities by $41 and decreased goodwill by $391.

	(In thousands)
Inventories	$	1,549
Accounts receivable		573
Other current assets		53
Property, plant and equipment		151
Other assets		26
Deferred tax assets		2,674
Current liabilities		(947	)
Acquisition contingencies		(3,700	)
Net tangible assets acquired		379
Other intangible assets		2,000
Goodwill		18,621
Total net assets acquired	$	21,000

Total net assets acquired as of January 4, 2018, are all part of the Company’s only operating segment. Fair values are based on management’s preliminary estimates and assumptions including variations of the income approach, the cost approach and the market approach. Other intangible assets include patents, trademarks, and selling and marketing relationships.

The Company believes that the acquisition of Zyga has offered and continues to offer the potential for substantial strategic and financial benefits. The transaction further advances our strategic transformation focused on reducing complexity, driving operational excellence and accelerating growth. The Company believes the acquisition will enhance stockholder value through, among other things, enabling the Company to capitalize on the following strategic advantages and opportunities:

• Zyga’s innovative minimally invasive treatment should accentuate our spine portfolio and opens significant opportunities to accelerate our Spine-focused expansion strategy.

• Zyga should leverage the core competencies of our Spine franchise by pursuing niche differentiated products, to gain scale and customer retention and support portfolio pull-through.

These potential benefits resulted in the Company paying a premium for Zyga resulting in the recognition of $18,621 of goodwill assigned to the Company’s only operating segment and reporting unit.

The amount of Zyga’s revenues and net loss since the January 4, 2018 acquisition date, included in the Company’s Condensed Consolidated Statement of Comprehensive Loss for the quarter ended March 31, 2018, excluding acquisition related costs of approximately $800, are $1,160 and $760, respectively.

Basic net loss per share		(0.01	)		(0.02	)
Diluted net loss per share		(0.01	)		(0.02	)

The pro forma results have been prepared for comparative purposes only and are not necessarily indicative of the actual results of operations had the acquisition taken place as of the beginning of the periods presented, or the results that may occur in the future. These amounts exclude costs incurred which are directly attributable to the acquisition, and which do not have a continuing impact on the combined companies’ operating results.

The Company is currently completing its analysis of the purchase price allocation which it expects to complete by December 31, 2018.

5. Stock-Based Compensation

The Company’s policy is to grant stock options at an exercise price equal to 100% of the market value of a share of common stock at closing on the date of the grant. The Company’s stock options generally have five toten-year contractual terms and vest over a one to five-year period from the date of grant. The Company’s policy is to grant restricted stock awards at a fair value equal to 100% of the market value of a share of common stock at closing on the date of the grant. The Company’s restricted stock awards generally vest over one to three-year periods.

2018 Incentive Compensation Plan –On April 30, 2018, the Company’s stockholders approved and adopted the 2018 Incentive Compensation Plan (the “2018 Plan”). The 2018 Plan provides for the grant of incentive and nonqualified stock options and restricted stock to key employees, including officers and directors of the Company and consultants and advisors. The 2018 Plan allows for up to 5,726,035 shares of common stock to be issued with respect to awards granted.

2015 Incentive Compensation Plan –On April 14, 2015, the Company’s stockholders approved and adopted the 2015 Incentive Compensation Plan (the “2015 Plan”). The 2015 Plan provided for the grant of incentive and nonqualified stock options and restricted stock to key employees, including officers and directors of the Company and consultants and advisors. The 2015 Plan allowed for up to 4,656,587 shares of common stock to be issued with respect to awards granted. With the adoption of the 2018 Plan, new stock options and restricted stock may no longer be awarded under the 2015 Plan.

Stock Options

As of June 30, 2018, there was $3,143 of total unrecognized stock-based compensation related to nonvested stock options. The expense related to these stock options is expected to be recognized over a weighted-average period of 1.89 years.

For the three months ended June 30, 2018 and 2017, approximately 1,590,662 and 1,350,051, respectively, and for the six months ended June 30, 2018 and 2017, approximately 1,447,911 and 2,422,661, respectively, of issued stock options were not included in the computation of diluted net income per common share because they were anti-dilutive because their exercise price exceeded the market price. For the three months ended June 30, 2018 and 2017, options to purchase 659,785 and 1,005,138, respectively, and for the six months ended June 30, 2018 and 2017, options to purchase 618,776 and 687,268, respectively, of common stock were not included in the computation of diluted loss per share because dilutive shares are not factored into this calculation when a net loss is reported.

For the three and six months ended June 30, 2018 and 2017, 50,000 shares of convertible preferred stock and accrued but unpaid dividends were anti-dilutive on an asif-converted basis and were not included in the computation of diluted net income (loss) per common share.

On June 5, 2018, the Company entered into a Credit Agreement (the “2018 Credit Agreement”), as a borrower with JP Morgan Chase Bank, N.A., as lender (together with the various financial institutions as in the future may become parties thereto, the “Lenders”) and as administrative agent for the Lenders. The 2018 Credit Agreement provides for a revolving credit facility in the aggregate principal amount of up to $100,000 (the “Facility”). The Company will be able to, at its option, and subject to customary conditions and Lender approval, request an increase to the Facility by up to $50,000.

The Facility is guaranteed by the Company’s domestic subsidiaries and is secured by: (i) substantially all of the assets of the Company and Pioneer Surgical; (ii) substantially all of the assets of each of the Company’s domestic subsidiaries; and (iii) 65% of the stock of the Company’s foreign subsidiaries.

The initial borrowings made under the 2018 Credit Agreement will bear interest at a rate per annum equal to the monthly REVLIBOR30 Rate (“CBFR Loans”) plus an adjustable margin of up to 2.00% (the “CBFR Rate”). The Company may elect to convert the interest rate for the initial borrowings to a rate per annum equal to the adjusted LIBO Rate (“Eurodollar Loans”) plus an adjustable margin of up to 2.00% (the “Eurodollar Rate”). For all subsequent borrowings, the Company may elect to apply either the CBFR Rate or Eurodollar Rate. The applicable margin is subject to adjustment after the end of each fiscal quarter, based upon the Company’s average quarterly availability. The maturity date of the Facility is June 5, 2023. The Company may make optional prepayments on the Facility without penalty. The Company paid certain customary closing costs and bank fees upon entering into the 2018 Credit Agreement.

The Company is subject to certain affirmative and negative covenants, including (but not limited to), covenants limiting the Company’s ability to: incur certain additional indebtedness; create certain liens; enter into sale and leaseback transactions; and consolidate or merge with, or convey, transfer or lease all or substantially all of its assets to another person. During any period beginning on a date that either (i) a default has occurred and is continuing under the loan documents entered into by the Company in conjunction with the Credit Agreement (the “Loan Documents”) or (ii) availability under the Facility is less than the specified covenant testing threshold, and continuing until either (a) no default has occurred and is continuing under the Loan Documents or (b) availability under the Facility is greater than or equal to the specified covenant testing threshold for thirty (30) consecutive days, respectively, (the “Covenant Testing Period”) the Company is required to maintain a minimum fixed charge coverage ratio of at least 1.00:1.00 (the “Required Minimum Fixed Charge Coverage Ratio”). The Required Minimum Fixed Charge Coverage Ratio is measured on the last day of each calendar month during the Covenant Testing Period (each a “Calculation Date”), and is calculated using the minimum fixed charge coverage ratio for the twelve (12) consecutive months ending on each Calculation Date. The amounts owed under the 2018 Credit Agreement may be accelerated upon the occurrence of certain events of default customary for facilities for similarly rated borrowers.

At June 30, 2018, the interest rate for the Facility was 3.73%. As of June 30, 2018, there was $54,425 outstanding on the Facility and total remaining available credit on the Facility was $35,129. The Company’s ability to access the Facility is subject to and can be limited by the Company’s compliance with the Company’s financial and other covenants. The Company was in compliance with the financial covenants related to the Facility as of June 30, 2018.

For the three months ended June 30, 2018 and 2017, interest expense associated with the amortization of debt issuance costs was $365 and $150, respectively, and for the six months ended June 30, 2018 and 2017, interest expense associated with the amortization of debt issuance costs was $423 and $262, respectively. For the three and six months ended June 30, 2018, loss on extinguishment of debt associated with refinancing the Company’s debt was $309.

14. Other long-term liabilities

15. Income Taxes

The Company expects its deferred tax assets of $14,448, net of the valuation allowance at June 30, 2018 of $7,381, to be realized through the generation of future taxable income and the reversal of existing taxable temporary differences.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Legislation”). The Tax Legislation makes broad and complex changes to the U.S. tax code including, but not limited to the following:

• Reduction of the U.S. federal corporate tax rate from 35% to 21%

• Requiring a transition tax on certain unrepatriated earnings of foreign subsidiaries

• Bonus depreciation that will allow for full expensing of qualified property

• Elimination of the corporate alternative minimum tax

• The repeal of the domestic production activity deduction

• Limitations on the deductibility of certain executive compensation

• Limitations on net operating losses generated after December 31, 2017

In addition, beginning in 2018, the Tax Legislation includes a global intangiblelow-taxed income (“GILTI”) provision, which as currently interpreted by the Company, requires a tax on foreign earnings in excess of a deemed return on tangible assets of foreign subsidiaries. The Company has elected an accounting policy to account for GILTI as a period cost if incurred, rather than recognizing deferred taxes for temporary basis differences expected to reverse as a result of GILTI. Other provisions of the Tax Legislation continue to be assessed.

The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Legislation. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Legislation enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, the Company must reflect the income tax effects of those aspects of the Tax Legislation for which the accounting under ASC 740 is complete. To the extent that the Company’s accounting for certain income tax effects of the Tax Legislation is incomplete, but the Company is able to determine a reasonable estimate, it must record a provisional estimate in the consolidated financial statements. If the Company cannot determine a provisional estimate, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Legislation.

In connection with our initial analysis of the impact of the Tax Legislation, the Company has recorded provisional tax expense of $2,187 in the period ending December 31, 2017. This provisional tax expense consists of $1,436 to revalue the Company’s deferred tax assets using the reduced corporate tax rate and $751 related to the transition tax. Given the complexity of the Tax Legislation and anticipated guidance from the U.S. Treasury about implementing the Tax Legislation, the Company’s analysis and accounting for the income tax effects of the Tax Legislation is preliminary. The amounts recorded by the Company to revalue its deferred tax assets and impact of the transition tax are estimates. The Company has not fully completed its analysis of certain aspects of the Tax Legislation that could result in adjustments to the revaluation of the Company’s deferred tax assets, and its analysis and calculation of foreign earnings subject to the transition tax. Upon completion of the Company’s analysis, these estimates may be adjusted through income tax expense in the consolidated financial statement.

The Company evaluates the need for deferred tax asset valuation allowances based on a more likely than not standard. The ability to realize deferred tax assets depends on the ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction.

The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available positive and negative evidence. It is difficult to conclude a valuation allowance is not required when there is significant objective and verifiable negative evidence, such as cumulative losses in recent years. The Company utilizes a rolling three-years of actual results as the primary measure of cumulative losses in recent years.

On a rolling three-year basis, the Company’s consolidated U.S. operations are in a cumulative income position. However, one U.S. entity (“Entity”) is in a three-year cumulative loss position. Future taxable income exclusive of reversing temporary differences and carryforwards is one source of taxable income available that can be used to realize tax benefits. During 2017, the Company undertook various cost reduction activities to reduce complexity and increase operational excellence within the organization. The Entity anticipates generating significant cost savings from the various cost reduction activities. After adjusting the Entity’s cumulative losses to include the projected costs savings, the Entity’s operations project future profits sufficient to utilize the Entity’s separate state deferred tax assets before expiration. The Company considers this objectively verifiable evidence that all its U.S. deferred tax assets are more likely than not realizable.

16

The Company’s foreign operation is in a three-year cumulative loss position. As a result, the Company has recorded a full valuation allowance on its foreign subsidiary’s deferred tax assets.

As such, valuation allowances of $7,381 and $7,258 have been established at June 30, 2018 and December 31, 2017, respectively, against a portion of the deferred tax assets.

The Company will continue to regularly assess the realizability of our deferred tax assets. Changes in historical earnings performance and future earnings projections, among other factors, may cause the Company to adjust its valuation allowance, which would impact the Company’s income tax expense in the period the Company determines that these factors have changed.

During the three months ended June 30, 2018, the Internal Revenue Service (“IRS”) completed its examination of the Company’s 2015 U.S. federal income tax return. No material adjustments were recorded to the Company’s condensed consolidated financial statements as a result of the examination.

19. Legal Actions

The Company is, from time to time, involved in litigation relating to claims arising out of its operations in the ordinary course of business. The Company believes that none of these claims that were outstanding as of June 30, 2018, will have a material adverse impact on its financial position or results of operations.

Coloplast — The Company is presently named asco-defendant along with other companies in a small percentage of the transvaginal surgical mesh (“TSM”) mass tort claims being brought in various state and federal courts. The TSM litigation has as its catalyst various Public Health Notifications issued by the U.S. Food and Drug Administration (“FDA”) with respect to the placement of certain TSM implants that were the subject of 510k regulatory clearance prior to their distribution. The Company does not process or otherwise manufacture for distribution in the U.S. any implants that were the subject of these FDA Public Health Notifications. The Company denies any allegations against it and intends to continue to vigorously defend itself.

In addition to claims made directly against the Company, Coloplast, a distributor of TSM’s and certain allografts processed and private labeled for them under a contract with the Company, has also been named as a defendant in individual TSM cases in various federal and state courts. Coloplast requested that the Company indemnify or defend Coloplast in those claims which allege injuries caused by the Company’s allograft implants, and on April 24, 2014, Coloplast sued RTI Surgical, Inc. in the Fourth Judicial District of Minnesota for declaratory relief and breach of contract. On December 11, 2014, Coloplast entered into a settlement agreement with RTI Surgical, Inc. and Tutogen Medical, Inc. (the “Company Parties”) resulting in dismissal of the case. Under the terms of the settlement agreement, the Company Parties are responsible for the defense and indemnification of two categories of present and future claims: (1) tissue only (where Coloplast is solely the distributor of Company processed allograft tissue and no Coloplast-manufactured or distributed synthetic mesh is identified) (“Tissue Only Claims”), and (2) tissue plusnon-Coloplast synthetic mesh(“Tissue-Non-Coloplast Claims”) (the Tissue Only Claims and theTissue-Non-Coloplast Claims being collectively referred to as “Indemnified Claims”). As of June 30, 2018, there are a cumulative total of 1,157 Indemnified Claims for which the Company Parties are providing defense and indemnification. The defense and indemnification of these cases are covered under the Company’s insurance policy subject to a reservation of rights by the insurer.

Based on the current information available to the Company, the impact that current or any future TSM litigation may have on the Company cannot be reasonably estimated.

The Company’s accounting policy is to accrue for legal costs as they are incurred.

20. Regulatory Actions

On September 30, 2014, the Company received a letter from the FDA regarding its map3^® cellular allogeneic bone graft. The letter addresses some technical aspects of the processing of the map3^® allograft, as well as language included on the Company’s website. Following the 2014 letter, the FDA conducted anon-site inspection of the Company’s Alachua, Florida facility in April 2017 to assess compliance of the manufacturing and quality controls for its map3^® allograft products to the 21 CFR Part 211 (GMP) regulations. A form 483 was issued by the FDA outlining 9 instances of observednon-compliance. The Company has worked diligently to resolve all cited observations in a timely manner, however, on November 9, 2017, the FDA issued a Warning Letter to the Company related to the map3^® allograft. The letter reiterated the FDA’s concerns regarding the classification and manufacturing of the map3^® allograft. There was no requirement to cease production or to recall distributed allografts from the market. The Company is working diligently and collaboratively with FDA to resolve any concerns regarding the map3^® allografts and the Company is maintaining ongoing dialogue with the FDA. Comprehensive packages of data have been provided to address the FDA’s comments. The Company has also provided the FDA with clarifying information regarding the technical components of the implant processing. The Company believes that in both developing and processing of map3^®, the Company properly considered the relevant regulatory requirements. Additionally, the Company has removed certain information from its website. The Company is committed to resolving the concerns raised by the FDA and has extended an invitation to the FDA for purposes of developing a mutually agreeable plan toward such resolution. The scheduling of such meeting remains pending and, as a result however, it is not possible to predict the specific outcome or timing of a resolution at this time.

18

During the second quarter 2018 the Company, based on its ongoing dialogue with the FDA and the continued negative impact of the warning letter on map3^® distributions, reduced its forecasted distributions for map3^® allografts. The reduction in the forecasted distributions was considered an impairment triggering event for the related asset group under the guidance per ASC 360 – Property, Plant, and Equipment. As a result, the Company completed an asset group impairment test utilizing revised long-term forecasts and determined the carrying value was not recoverable. As a result of the valuation analysis, an impairment charge of $1,797 was recorded against property, plant and equipment, and an impairment charge of $2,718 was recorded against acquired licensing rights. Additionally, management performed an analysis to assess the amount of map3^® inventory which would more likely than not, not be distributed prior to the inventory’s expiring shelf life and should therefore be written down. Based on the analysis awrite-off of $6,559 was recorded which has been reflected within the Costs of processing and distribution line within the Condensed Consolidated Statement of Comprehensive Loss. The asset group impairment was also a trigger for goodwill impairment under ASC 350 – Intangibles – Goodwill and Other. No impairment charges were recorded as a result of the testing.

21. Segment Data

The Company distributes human tissue, bovine and porcine animal tissue, metal and synthetic implants through various distribution channels. The Company operates in one reportable segment composed of four lines of business. Effective January 1, 2018, the reporting of the Company’s lines of business are composed primarily of four categories: spine; sports; original equipment manufacturer (“OEM”) and international. The Company’s previous lines of business were composed of: spine; sports medicine and orthopedics; surgical specialties; cardiothoracic; international; and OEM. Effective January 1, 2018, the other revenues category is included in the OEM line of business. The prior year comparable revenue information has been restated to conform to the current year presentation. The Company believes that the change in the reporting of the Company’s lines of business is aligned with our focused strategy of reducing complexity and better understanding of our lines of business. Additionally, on August 3, 2017, we completed the sale of substantially all of the assets related to our CT Business to A&E Advanced Closure Systems, LLC (a subsidiary of A&E Medical Corporation) (“A&E”). In connection with the CT Business sale, we entered into a multi-year Contract Manufacturing Agreement with A&E whereby we continue to support the CT Business under A&E’s ownership through the manufacturing of existing products, which generates revenue for our OEM business.

Management Overview

RTI Surgical is a global surgical implant company that designs, develops, manufactures and distributes biologic, metal and synthetic implants. Our implants are used in orthopedic, spine, sports medicine, general surgery, trauma and other surgical procedures to repair and promote the natural healing of human bone and other human tissues and improve surgical outcomes. We manufacture metal and synthetic implants and process donated human musculoskeletal and other tissue and bovine and porcine animal tissue in producing allograft and xenograft implants using our proprietary BIOCLEANSE^®, TUTOPLAST^® and CANCELLE^® SP sterilization processes. We process tissue at our facilities in Alachua, Florida and Neunkirchen, Germany and manufacture metal and synthetic implants in Marquette, Michigan and Greenville, North Carolina. We are accredited in the U.S. by the American Association of Tissue Banks and we are a member of AdvaMed. Our implants are distributed directly to hospitals throughout the U.S. and in more than 40 countries worldwide with the support of both our and third-party representatives as well as through larger purchasing companies. We were founded in 1997 and are headquartered in Alachua, Florida.

Domestic distributions and services accounted for 90% of total revenues in the first six months of 2018. Most of our implants are distributed directly to healthcare providers, hospitals and other healthcare facilities through a direct distribution force and through various original equipment manufacturer (“OEM”) relationships.

International distributions and services accounted for 10% of total revenues in the first six months of 2018. Our implants are distributed in over 40 countries through a direct distribution force in Germany and through stocking distributors in the rest of the world outside of Germany and the U.S.

We are implementing a focused strategy to expand our spine and OEM operations and create long-term, profitable growth for the company. In 2017, we introduced a new management team with extensive experience in an effort to spearhead these efforts. The core components of our strategy are:

• Reduce Complexity. We are working to reduce complexity in our organization by divestingnon-core assets and investing in core competencies.

• Drive Operational Excellence. We are working to optimize material cost and drive operational efficiency to reduce other direct costs by pursuing world class manufacturing.

• Accelerate Growth. We are investing in innovative, niche high growth product categories leveraging core competency in the spine market; utilizing core technologies to expand OEM relationships and drive organic growth; and building relevant scale in our spinal portfolio to improve importance to the consolidating healthcare market driven by integrated delivery networks and group purchasing organizations.

In line with our strategy, on January 4, 2018, the Company acquired Zyga Technology, Inc. (“Zyga”), a leading spine-focused medical device company that develops and produces innovative minimally invasive devices to treat underserved conditions of the lumbar spine. Zyga’s primary product is the SImmetry^® Sacroiliac Joint Fusion System. Under the terms of the merger agreement dated January 4, 2018, the Company acquired Zyga for $21.0 million in consideration paid at closing (consisting of borrowings of $18.0 million on our revolving credit facility and $3.0 million cash on hand), $1.0 million contingent upon the successful achievement of a clinical milestone, and a revenue based earnout consideration of up to $35.0 million.

We believe this is a significant step toward focusing our business and advancing our efforts to generate predictable and sustainable operating results through disciplined execution and building scale to extend distribution of our products in those areas that offer the greatest opportunities to benefit our patients and shareholders.

21

We continue to maintain our commitment to research and development and the introduction of new strategically targeted allograft, xenograft, metal and synthetic implants as well as focused clinical efforts to support their acceptance in the marketplace. In addition, we consider strategic acquisitions from time to time for new implants and technologies intended to augment our existing implant offerings, as well as strategic dispositions from time to time in response to market trends or industry developments.

Critical Accounting Policies

There have been no significant changes to our critical accounting policies from those disclosed in our 2017 Annual Report on Form10-K except for the adoption of the new standard related to revenue recognition, as described in Note 3 to the interim unaudited condensed consolidated financial statements.

Three Months Ended June 30, 2018 Compared With Three Months Ended June 30, 2017

Revenues

Total revenues - Our total revenues decreased $1.4 million, or 2.0%, to $70.7 million for the three months ended June 30, 2018, compared to $72.1 million for the three months ended June 30, 2017. Excluding cardiothoracic revenues for the three months ended June 30, 2017, our total revenues increased $2.2 million, or 3.3%, primarily due to timing of delivery to certain OEM distributors, primarily in the dental and trauma markets.

Spine - Revenues from spine implants decreased $485,000, or 2.5%, to $18.9 million for the three months ended June 30, 2018, compared to $19.4 million for the three months ended June 30, 2017. Spine revenues decreased primarily as a result of decreased distributions of our map3^® and nanOss^® implants.

Sports -Revenues from sports allografts decreased $263,000, or 1.8%, to $14.2 million for the three months ended June 30, 2018, compared to $14.5 million for the three months ended June 30, 2017. Sports revenues decreased primarily as a result of decreased distributions of our biologic implants, partially offset by growth in our dermis based implants.

OEM -Revenues from OEM increased $3.2 million, or 11.4%, to $31.2 million for the three months ended June 30, 2018, compared to $28.0 million for the three months ended June 30, 2017. OEM revenues increased primarily as a result of higher orders and due to timing of delivery to certain OEM distributors, primarily in the dental and trauma markets.

International – Revenues from international include distributions from our foreign affiliates as well as domestic export revenues. International revenues decreased $201,000, or 3.0%, to $6.4 million for the three months ended June 30, 2018, compared to $6.6 million for the three months ended June 30, 2017. International revenues decreased primarily as a result of lower distributions in Asia Pacific due to timing of delivery to certain international distributors.

Cardiothoracic - On August 3, 2017, we completed the sale of substantially all of the assets related to our Cardiothoracic closure business (the “CT Business”) to A&E Advanced Closure Systems, LLC (a subsidiary of A&E Medical

22

Corporation) (“A&E”). Additionally, we have entered into a multi-year Contract Manufacturing Agreement with A&E whereby we continue to support the CT Business under A&E’s ownership through the manufacturing of existing products, which generates revenue for our OEM business.

Costs of Processing and Distribution

Costs of processing and distribution increased $5.5 million, or 15.6%, to $40.6 million for the three months ended June 30, 2018, compared to $35.2 million for the three months ended June 30, 2017. Costs of processing and distribution increased as a percentage of revenues from 48.7% for the three months ended June 30, 2017 to 57.5% for the three months ended June 30, 2018. Costs of processing and distribution as a percentage was negatively impacted by an inventorywrite-off of $6.6 million related to decreased distributions of our map3^® implant; preliminary purchase accounting step up adjustments to Zyga inventory of $250,000 charged to costs of processing and distribution as inventory was sold; and changes in distribution mix. Adjusted for the impact of the inventorywrite-off and purchase accounting step up, costs of processing and distribution as a percentage of revenues were 47.9% for the three months ended June 30, 2018.

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses decreased $230,000, or 0.8%, to $29.3 million for the three months ended June 30, 2018, from $29.5 million for the three months ended June 30, 2017. The decrease was primarily due to lower variable compensation and distributor commission expenses on spine and sports revenue distributions. Marketing, general and administrative expenses increased as a percentage of revenues from 40.9% for the three months ended June 30, 2017 to 41.4% for the three months ended June 30, 2018.

Research and Development Expenses

Research and development expenses decreased $470,000, or 12.6%, to $3.3 million for the three months ended June 30, 2018, from $3.7 million for the three months ended June 30, 2017. The decrease was primarily due to lower compensation and project related expenses. Research and development expenses decreased as a percentage of revenues from 5.2% for the three months ended June 30, 2017, to 4.6% for the three months ended June 30, 2018.

Severanceand Restructuring Costs

There are no severance and restructuring costs for the three months ended June 30, 2018 as compared to $3.4 million of expenses for the three months ended June 30, 2017.

Asset impairment and abandonments

Asset impairment and abandonments related to decreased forecasted distributions of our map3^® implant for the three months ended June 30, 2018 was $4.5 million. There were no asset impairment and abandonments for the three months ended June 30, 2017.

Net Other Expense

Net other expense, which includes interest expense, interest income, loss on extinguishment of debt and foreign exchange gain, increased $161,000, or 16.3%, to $1.2 million for the three months ended June 30, 2018, from $1.0 million for the three months ended June 30, 2017. The increase in net other expense is primarily due to the loss on extinguishment of debt of $309,000 as a result of refinancing our debt, offset by lower interest expense of $138,000 as a result of lower interest rate applied to our average debt balance as compared to the prior year period.

Income Tax Benefit (Provision)

Income tax benefit for the three months ended June 30, 2018, was $2.7 million compared to income tax provision of $1.0 million for the three months ended June 30, 2017. Our effective tax rate for the three months ended June 30, 2018, was 33.1% compared to 154.8% for the three months ended June 30, 2017. Our effective tax rate for the three months ended June 30, 2018, was primarily impacted due to recording a discrete tax benefit of $3.1 million relating to inventorywrite-off and asset impairment and abandonments due to decreased forecasted distributions of our map3^® implant; recording a discrete tax benefit of $415,000 relating to previously unrecognized tax benefits; the U.S. federal corporate tax rate decreasing from 35% to 21% (The U.S. federal corporate rate decreased as a result of the Tax Cuts and Jobs Act (the “Tax Legislation”) which was enacted on December 22, 2017) andnon-deductible executive compensation. Adjusted for the impact of the two discrete tax items andnon-deductible executive compensation, our effective tax rate was 19.4% for the three months ended June 30, 2018.

Total revenues - Our total revenues decreased $1.5 million, or 1.0%, to $140.6 million for the six months ended June 30, 2018, compared to $142.1 million for the six months ended June 30, 2017. Excluding cardiothoracic revenues for the six months ended June 30, 2017, our total revenues increased $5.3 million, or 3.9%, primarily due to timing of delivery to certain OEM distributors, primarily in the dental and trauma markets.

23

Spine - Revenues from spine implants decreased $1.6 million, or 3.9%, to $38.2 million for the six months ended June 30, 2018, compared to $39.8 million for the six months ended June 30, 2017. Spine revenues decreased primarily as a result of decreased distributions of our map3^® and nanOss^® implants.

OEM revenues increased primarily as a result of higher orders and due to timing of delivery to certain OEM distributors, primarily in the dental and trauma markets.

International – Revenues from international include distributions from our foreign affiliates as well as domestic export revenues. International revenues increased $239,000, or 1.8%, to $13.5 million for the six months ended June 30, 2018, compared to $13.2 million for the six months ended June 30, 2017. International revenues increased primarily as a result of higher distributions in Europe due to a strengthened and focused distribution channel, partially offset by lower distributions in Asia Pacific due to timing of delivery to certain international distributors.

Cardiothoracic - On August 3, 2017, we completed the sale of substantially all of the assets related to our Cardiothoracic closure business (the “CT Business”) to A&E Advanced Closure Systems, LLC (a subsidiary of A&E Medical Corporation) (“A&E”). Additionally, we have entered into a multi-year Contract Manufacturing Agreement with A&E whereby we continue to support the CT Business under A&E’s ownership through the manufacturing of existing products, which generates revenue for our OEM business.

Costs of Processing and Distribution

Costs of processing and distribution increased $7.5 million, or 10.9%, to $76.9 million for the six months ended June 30, 2018, compared to $69.3 million for the six months ended June 30, 2017. Costs of processing and distribution increased as a percentage of revenues from 48.8% for the six months ended June 30, 2017 to 54.7% for the six months ended June 30, 2018. Costs of processing and distribution as a percentage was negatively impacted by an inventorywrite-off of $6.6 million related to decreased distributions of our map3^® implant; $1.0 million as a result ofwriting-off certain obsolete quantities primarily of bone graft substitute inventory due to the rationalization of our international distribution infrastructure; preliminary purchase accounting step up adjustments to Zyga inventory of $456,000 charged to costs of processing and distribution as inventory was sold; and changes in distribution mix. Adjusted for the impact of the inventorywrite-off;write-off of obsolete inventory and the purchase accounting step up, costs of processing and distribution as a percentage of revenues were 49.0% for the six months ended June 30, 2018.

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses decreased $1.5 million, or 2.6%, to $57.7 million for the six months ended June 30, 2018, from $59.2 million for the six months ended June 30, 2017. The decrease was primarily due to lower variable compensation and distributor commission expenses on spine and sports revenue distributions. Marketing, general and administrative expenses decreased as a percentage of revenues from 41.6% for the six months ended June 30, 2017 to 41.0% for the six months ended June 30, 2018.

Research and Development Expenses

Research and development expenses decreased $737,000, or 9.9%, to $6.7 million for the six months ended June 30, 2018, from $7.4 million for the six months ended June 30, 2017. The decrease was primarily due to lower compensation and project related expenses. Research and development expenses decreased as a percentage of revenues from 5.2% for the six months ended June 30, 2017, to 4.8% for the six months ended June 30, 2018.

Severance and Restructuring Costs

Severance and restructuring costs related to the reduction of our organizational structure, primarily driven by rationalization of our international operating infrastructure, resulted in $884,000 of expenses for the six months ended June 30, 2018 as compared to $7.8 million of expenses for the six months ended June 30, 2017.

24

Asset impairment and abandonments

Asset impairment and abandonments primarily related to decreased forecasted distributions of our map3^® implant for the six months ended June 30, 2018 was $4.6 million. There were no asset impairment and abandonments for the six months ended June 30, 2017.

Acquisition and integration expenses

Acquisition and integration expenses related to the purchase of Zyga resulted in $800,000 of expenses for the six months ended June 30, 2018. There were no acquisition and integration expenses for the six months ended June 30, 2017.

Net Other Expense

Net other expense, which includes interest expense, interest income, loss on extinguishment of debt and foreign exchange gain, increased $137,000, or 7.7%, to $1.9 million for the six months ended June 30, 2018, from $1.8 million for the six months ended June 30, 2017. The increase in net other expense is primarily due to the loss on extinguishment of debt of $309,000 as a result of refinancing our debt, offset by lower interest expense of $122,000 as a result of lower interest rate applied to our average debt balance as compared to the prior year period.

Income Tax Benefit (Provision)

Income tax benefit for the six months ended June 30, 2018, was $2.5 million compared to income tax provision of $116,000 for the six months ended June 30, 2017. Our effective tax rate for the six months ended June 30, 2018, was 28.1% compared to 3.4% for the six months ended June 30, 2017. Our effective tax rate for the six months ended June 30, 2018, was primarily impacted due to recording a discrete tax benefit of $3.1 million relating to inventorywrite-off and asset impairment and abandonments due to decreased forecasted distributions of our map3^® implant; recording a discrete tax benefit of $415,000 relating to previously unrecognized tax benefits; the U.S. federal corporate tax rate decreasing from 35% to 21% (The U.S. federal corporate rate decreased as a result of the Tax Cuts and Jobs Act (the “Tax Legislation”) which was enacted on December 22, 2017) andnon-deductible executive compensation. Adjusted for the impact of the two discrete tax items andnon-deductible executive compensation, our effective tax rate was 37.4% for the three months ended June 30, 2018.

Non-GAAP Financial Measures

We utilize certain financial measures that are not calculated based on Generally Accepted Accounting Principles (“GAAP”). Certain of these financial measures are considered“non-GAAP” financial measures within the meaning of Item 10 of RegulationS-K promulgated by the SEC. We believe thatnon-GAAP financial measures provide an additional way of viewing aspects of our operations that, when viewed with the GAAP results, provide a more complete understanding of our results of operations and the factors and trends affecting our business. Thesenon-GAAP financial measures are also used by our management to evaluate financial results and to plan and forecast future periods. However,non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.Non-GAAP financial measures used by us may differ from thenon-GAAP measures used by other companies, including our competitors.

To supplement our unaudited condensed consolidated financial statements presented on a GAAP basis, we disclose certainnon-GAAP financial measures that exclude certain amounts, includingnon-GAAP net income applicable to common shares, adjusted. The calculation of the tax effect on the adjustments between GAAP net loss applicable to common shares andnon-GAAP net income applicable to common shares is based upon our estimated annual GAAP tax rate, adjusted to account for items excluded from GAAP net loss applicable to common shares in calculatingnon-GAAP net income applicable to

25

common shares. Reconciliations of each of thesenon-GAAP financial measures to the corresponding GAAP measures are included in the reconciliation below:

	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2018			2017			2018			2017

The following is an explanation of the adjustments that management excluded as part of thenon-GAAP measures for the three and six months ended June 30, 2018 and 2017, as well as the reasons for excluding the individual items:

Severance and restructuring costs – This adjustment represents costs relating to the reduction of our organizational structure. Management removes the amount of these costs from our operating results to supplement a comparison to our past operating performance.

Asset impairment and abandonments – This adjustment represents an asset impairment and abandonments related to decreased forecasted distributions of our map3^® implant. Management removes the amount of these costs from our operating results to supplement a comparison to our past operating performance.

Acquisition and integration expenses – This adjustment represents charges relating to acquisition and integration expenses due to the purchase of Zyga. Management removes the amount of these costs from our operating results to supplement a comparison to our past operating performance.

Inventorywrite-off – This adjustment represents charges relating to an inventorywrite-off due to the rationalization of our international distribution infrastructure and an inventorywrite-off related to decreased forecasted distributions of our map3^® implant. Management removes the amount of these costs from our operating results to supplement a comparison to our past operating performance.

Inventory purchase price adjustment – This adjustment represents the purchase price effects of acquired Zyga inventory that was sold during the six months ended June 30, 2018. Management removes the amount of these costs from our operating results to supplement a comparison to our past operating performance.

Loss on extinguishment of debt – This adjustment represents costs relating to refinancing our debt. Management removes the amount of these costs from our operating results to supplement a comparison to our past operating performance.

Liquidity and Capital Resources

Our working capital at June 30, 2018, decreased $7.5 million to $125.2 million from $132.7 million at December 31, 2017, primarily as a result of the purchase of Zyga. We acquired Zyga for $21.0 million in consideration paid at closing, consisting of borrowings of $18.0 million on our revolving credit facility and $3.0 million cash on hand.

At June 30, 2018, we had 60 days of revenues outstanding in trade accounts receivable, an increase of 14 days compared to December 31, 2017. The increase was due to the increase in the receivable balance as a result of the Zyga acquisition. Additionally, the increase is driven by the longer period receivables remain outstanding for contracts with customers where inventory is exclusively built with no alternative use to us, and where revenue is recognized over time under ASC 606. Whereas previously, revenue and receivables were recorded at the time of shipment, they are now recorded over time, however, the customer is only billed at the time of shipment.

At June 30, 2018, we had 255 days of inventory on hand, a decrease of 43 days compared to December 31, 2017. The decrease in inventory days is primarily due to higher distributions; inventory obsolescence due to the rationalization of our international distribution infrastructure and an inventorywrite-off related to decreased forecasted distributions of our map3^® implant during the six months ended June 30, 2018. We believe that our inventory levels will be adequate to support ouron-going operations for the next twelve months.

26

We had $14.2 million of cash and cash equivalents at June 30, 2018. At June 30, 2018, our foreign subsidiaries held $1.9 million in cash. We intend to indefinitely reinvest the earnings of our foreign subsidiaries. We do not believe that this policy of indefinitely reinvesting the earnings of our foreign subsidiaries will have a material adverse effect on the business as a whole.

Our short and long-term obligations at June 30, 2018, increased $7.1 million to $53.4 million from $46.3 million at December 31, 2017. The increase in short and long-term obligations was primarily in connection with increased borrowing to finance the Zyga acquisition.

On January 4, 2018, we acquired Zyga, as discussed above under “Management Overview.”

On June 5, 2018, we entered into a Credit Agreement (the “2018 Credit Agreement”), as a borrower with JP Morgan Chase Bank, N.A., as lender (together with the various financial institutions as in the future may become parties thereto, the “Lenders”) and as administrative agent for the Lenders. The 2018 Credit Agreement provides for a revolving credit facility in the aggregate principal amount of up to $100 million (the “Facility”). We will be able to, at our option, and subject to customary conditions and Lender approval, request an increase to the Facility by up to $50 million.

The Facility is guaranteed by our domestic subsidiaries and is secured by: (i) substantially all of the assets of the Company and Pioneer Surgical; (ii) substantially all of the assets of each of our domestic subsidiaries; and (iii) 65% of the stock of our foreign subsidiaries.

The initial borrowings made under the 2018 Credit Agreement will bear interest at a rate per annum equal to the monthly REVLIBOR30 Rate (“CBFR Loans”) plus an adjustable margin of up to 2.00% (the “CBFR Rate”). We may elect to convert the interest rate for the initial borrowings to a rate per annum equal to the adjusted LIBO Rate (“Eurodollar Loans”) plus an adjustable margin of up to 2.00% (the “Eurodollar Rate”). For all subsequent borrowings, we may elect to apply either the CBFR Rate or Eurodollar Rate. The applicable margin is subject to adjustment after the end of each fiscal quarter, based upon our average quarterly availability. The maturity date of the Facility is June 5, 2023. We may make optional prepayments on the Facility without penalty. We paid certain customary closing costs and bank fees upon entering into the 2018 Credit Agreement.

We are subject to certain affirmative and negative covenants, including (but not limited to), covenants limiting our ability to: incur certain additional indebtedness; create certain liens; enter into sale and leaseback transactions; and consolidate or merge with, or convey, transfer or lease all or substantially all of its assets to another person. During any period beginning on a date that either (i) a default has occurred and is continuing under the loan documents entered into by us in conjunction with the Credit Agreement (the “Loan Documents”) or (ii) availability under the Facility is less than the specified covenant testing threshold, and continuing until either (a) no default has occurred and is continuing under the Loan Documents or (b) availability under the Facility is greater than or equal to the specified covenant testing threshold for thirty (30) consecutive days, respectively, (the “Covenant Testing Period”) we are required to maintain a minimum fixed charge coverage ratio of at least 1.00:1.00 (the “Required Minimum Fixed Charge Coverage Ratio”). The Required Minimum Fixed Charge Coverage Ratio is measured on the last day of each calendar month during the Covenant Testing Period (each a “Calculation Date”), and is calculated using the minimum fixed charge coverage ratio for the twelve (12) consecutive months ending on each Calculation Date. The amounts owed under the 2018 Credit Agreement may be accelerated upon the occurrence of certain events of default customary for facilities for similarly rated borrowers.

At June 30, 2018, the interest rate for the Facility was 3.73%. As of June 30, 2018, there was $54.4 million outstanding on the Facility and total remaining available credit on the Facility was $35.1 million. Our ability to access our Facility is subject to and can be limited by our compliance with our financial and other covenants. We were in compliance with the financial covenants related to our revolving credit facility as of June 30, 2018.

As of June 30, 2018, we believe that our working capital, together with our borrowing ability under the Facility, will be adequate to fund our ongoing operations for the next twelve months.

As of June 30, 2018, we have no materialoff-balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are subject to market risk from exposure to changes in interest rates based upon our financing, investing and cash management activities. We are exposed to interest rate risk in the United States and Germany. Changes in interest rates affect interest income earned on cash and cash equivalents and interest expense on revolving credit arrangements. We have not entered into derivative transactions related to cash and cash equivalents or debt. Our borrowings under our term loan and credit facility expose us to market risk related to changes in interest rates. As of June 30, 2018, our outstanding floating rate indebtedness totaled $54.4 million. The primary base interest rate is LIBOR. Other outstanding debt consists of fixed rate instruments. We do not expect changes in interest rates to have a material adverse effect on our income or our cash flows in 2018. However, we can give no assurance that interest rates will not significantly change in the future.

The value of the U.S. dollar compared to the Euro affects our financial results. Changes in exchange rates may positively or negatively affect revenues, gross margins, operating expenses and net income. Our international operations currently transact business primarily in the Euro. Assets and liabilities of foreign subsidiaries are translated at the period end exchange rate while revenues and expenses are translated at the average exchange rate for the period. Intercompany transactions are translated from the Euro to the U.S. dollar. We do not expect changes in exchange rates to have a material adverse effect on our income or our cash flows for the remainder of 2018. However, we can give no assurance that exchange rates will not significantly change in the future.

Item 4. Controls and Procedures

As of the end of the period covered by this report, an evaluation was performed on the effectiveness of the design and operation of our disclosure controls and procedures under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Disclosure controls and procedures include controls and other procedures that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures were effective as of the end of the period covered by this report.

There have not been any changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules13a-15(d) or15d-15(d) of the Exchange Act during the three months ended June 30, 2018 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
