The accompanying condensed consolidated balance sheet as of December 31, ~~2018,~~2019, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) related to a quarterly report on Form 10-Q. Certain information and note disclosures normally included in annual audited financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made in this Quarterly Report on Form 10-Q are adequate to make the information not misleading. The unaudited interim condensed consolidated financial statements reflect all adjustments, including normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the financial position and results of operations for the periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, ~~2018,~~2019, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 that was filed with the SEC on March ~~29, 2019.~~17, 2020. Operating results for the three and nine months ended September 30, ~~2019~~2020 are not necessarily indicative of the results that may be expected for the year ending December 31, ~~2019,~~2020, or any other future periods.

The accompanying condensed consolidated financial statements have been prepared ~~assuming that the Company will continue as~~on a going concern ~~and do not include any adjustments that might result from the outcome of this uncertainty. A going concern~~ basis, ~~of accounting~~which contemplates the ~~recovery~~realization of ~~the Company’s~~ assets and ~~the~~ satisfaction of ~~its~~ liabilities in the normal course of business.

At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within twelve months after the date the condensed consolidated financial statements are issued. The Company’s ~~annual~~evaluation entails analyzing prospective operating ~~plan projects that~~budgets and forecasts for expectations of the Company’s cash needs and comparing those needs to the current cash and cash equivalent balances, and availability under existing credit facilities.

The Company’s capital requirements over the next twelve months will depend on many factors, including the ability to achieve anticipated revenue, manage operating expense and the timing of required investments in inventory and instrument sets to support its ~~existing~~customers.

On October 16, 2020, the Company closed a public offering (the “Offering”) in which it issued and sold a total 13,142,855 shares of its common stock, including overallotment shares, at a price to the public of $8.75 per share. The net proceeds to the Company from the Offering were approximately $107.7 million. The Company’s working capital at September 30, ~~2019 of $85.8~~2020 was $38.5 million (including cash of ~~$57.8~~$15.7 million), which, ~~includes the net~~along with proceeds ~~of $54.0 million received in August 2019~~ from the Offering, ~~along with available draws on its working capital credit line with MidCap, allows~~ the Company expects to be able to fund its operations through at least one year subsequent to the date the condensed consolidated financial statements are issued. ~~The Company also has available an additional $20 million under the~~

The Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. In late 2019, a novel strain of Coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, COVID-19 has ~~incurred significant net losses since inception~~spread globally to all countries, including to the United States. The global spread of the virus has led to unprecedented restrictions on, and ~~has relied on its ability~~disruptions in business and personal activities, which include preventive and precautionary measures that governments, communities, business partners, and the Company have taken and continue to ~~fund its operations through revenues from~~take to manage the ~~sale~~impact and mitigate any further spread of ~~its products, equity financings and debt financings.

To date, the Company has ~~historically incurred losses, successful transition~~taken steps to ~~profitability~~help keep its workforce healthy and safe and is ~~dependent upon achieving a level of revenues adequate to support the Company’s cost structure. Operating losses~~assessing and ~~negative cash flows are expected to continue for at least the next year~~updating its plans on an ongoing basis, as ~~the Company continues to incur costs~~new information related to the ~~execution~~virus and its impact become available.

The Company's future results of ~~its operating plan~~operations and ~~introduction~~liquidity could be adversely impacted by delays in payments of ~~new products. In~~outstanding receivable amounts beyond normal payment terms, supply chain disruptions and uncertain demand, and the ~~future,~~impact of any further initiatives or programs that the Company may ~~need~~undertake to ~~seek additional funds from public~~address financial and ~~private equity~~operations challenges faced by its customers. As of the date of issuance of these condensed consolidated financial statements, the extent to which the pandemic may materially impact the Company's financial condition, liquidity, or ~~debt financings~~results of operations is uncertain. The Company intends to continue to actively monitor the pandemic and take the necessary and required steps to identify and mitigate any adverse impacts on, or ~~other sources~~risks to, fund its projected operating requirements. However, there is no guarantee that the Company will be able to obtain further financing, or do so on reasonable terms. If the Company is unable to raise additional funds on a timely basis, or at all, it would be materially adversely affected.

~~As more fully described in Note 5,~~ the Company’s ~~debt agreements include traditional lending and reporting covenants, including a financial covenant that requires~~business operations posed by the ~~Company to maintain a minimum fixed charge coverage ratio beginning in April 2020 and a minimum liquidity covenant~~spread of $5.0 million effective through March 2020. Should at any time the Company fail to maintain compliance with these covenants, the Company will need to seek waivers or amendments to the debt agreements. If the Company is unable to secure such waivers or amendments, it may be required to classify its obligations under the debt agreements in current liabilities on its consolidated balance sheet. The Company may also be required to repay all or a portion of outstanding indebtedness under the debt agreements, which would require the Company to obtain further financing. There is no assurance that the Company will be able to obtain further financing, or do so on reasonable terms.COVID-19.

Certain amounts in the condensed consolidated ~~statement of operations~~financial statements for the three and nine months ended September 30, ~~2018~~2019 have been reclassified to conform to the current ~~period's~~period’s presentation. These reclassifications include the depreciation expense for surgical instruments, which was reclassified, to be consistent with industry practice, out of cost of revenues and into sales, general and administrative expense on the Company’s consolidated statements of operations. This resulted in a reclassification of $1.3 million and $3.9 million of depreciation expense for the three and nine months ended September 30, 2018, respectively. In addition, general and administrative expense for 2018 was combined into a single line item with sales and marketing expense for a new expense line titled “Sales, general and administrative expense” and litigation-related expenses primarily pertaining to the ongoing litigation with NuVasive, Inc. were classified out of selling, general and administrative expense on the Company’s consolidated statement of operations for the three and nine months ended September 30, 2018 and onto its own expense line item. None of the adjustments had any effect on theThe adjustment did not impact prior period net loss.

The Company’s significant accounting policies are described in Note 2 to its audited consolidated financial statements for the year ended December 31, ~~2018,~~2019, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC on March ~~29, 2019.~~17, 2020. Except as discussed below, these accounting policies have not changed during the ~~three and~~ nine months ended September 30, ~~2019.~~2020.

Effective January 1, 2019, the Company adopted ASC No. 2016‑02, Leases (Topic 842) (“ASU 2016‑02” or “ASC 842”), which supersedes the current accounting for leases, using the modified retrospective transition method. The Company ~~has elected~~expensed certain costs related to ~~apply~~ the practical expedients allowed by the standard for existing leases. The new standard, while retaining two distinct types of leases, finance and operating, (i) requires lessees to record a right-of-use (“ROU”) asset and a related liabilityterminated tender offer for the ~~rights~~acquisition of EOS Imaging, which primarily include third-party advisory fees, legal fees and ~~obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar~~commitment fees related to current accounting, (ii) eliminates current real estate specific lease provisions, (iii) modifies the lease classification criteria and (iv) aligns many of the underlying lessor model principles with those in the new revenue standard. The Company determines the initial classification and measurement of its ROU asset and lease liabilities at the lease commencement date and thereafter, if modified. The Company recognizes a ROU asset for its operating leases with lease terms greater than 12 months. The lease term includes any renewal options and termination options that the Company is reasonably assured to exercise. The present value of lease payments is determined by using the incremental borrowing rate for operating leases determined by using the incremental borrowing rate of interest that the Company would pay to borrow on a collateralized basis an amount equal to the lease payments in a similar economic environment. The Company applied the new guidance to its existing facility lease at the time of adoption and recognized a ROU asset of $2.4 million and operating lease liability of $2.9 million as of March 31, 2019, the initial period of adoption, and removed the previous deferred rent balance under the previous lease guidance of approximately $0.6 million. The Company entered into another facility lease for smaller office space during the third quarter of 2019 and also applied this guidance to create an additional ROU asset and operating lease liability. The two leases are presented together on the Company’s condensed consolidated balance sheet.

Rent expense for operating leases is recognized on a straight-line basis over the reasonably assured lease term based on the total lease payments and is included in research and development and general and administrative expenses in the statements of operations.

In March 2019, the Company’s Convertible Note outstanding reached maturity and allowed for the noteholders to elect settlement in cash or shares of common stock. As the Convertible Note provided the holders the benefit to convert to shares of common stock, a beneficial conversion feature (“BCF”) with a calculated intrinsic fair value at issuance of $0.2 million existed as of the date the Convertible Note was able to be converted into shares of common stock. Although the holders elected for cash settlement, the BCF was required to be recognized as interest expense on the Company’s consolidated statement of operations and within additional paid-in-capital within the Company’s condensed consolidated statement of stockholders’ equity for the nine months ended September 30, 2019.transaction financing arrangements.

The carrying amount of financial instruments consisting of ~~cash, restricted~~ cash, trade accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses, accrued compensation and current portion of long-term debt included in the Company’s condensed consolidated financial statements are reasonable estimates of fair value due to their short maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, management believes the fair value of long-term debt approximates its carrying value.

Authoritative guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

The Company does not maintain any financial assets that are considered to be Level 1, Level 2 or Level 3 instruments as of September 30, ~~2019.~~ ~~The fair value of the contingent consideration liability assumed in the SafeOp acquisition was recorded as part of the purchase price consideration of the acquisition.~~ ~~The contingent consideration related to the SafeOp acquisition was classified within Level 3 of the fair value hierarchy as the Company was~~ using a probability-weighted income approach, utilizing significant unobservable inputs including the probability of achieving each of the potential milestones and an estimated discount rate related to the risks of the expected cash flows attributable to the milestones. ~~All the contingent milestones were achieved as of September 30, 2019.~~2020. During the second quarter of 2019, the Company issued a liability classified equity award to one of its executive officers. The award will be earned over a 4 year vesting period and upon a specific market condition. As the award will be cash settled, it is classified as a liability within Level 3 of the fair value hierarchy as the Company is using a probability-weighted income approach, utilizing significant unobservable inputs including the probability of achieving the specified market condition with the valuation updated at each reporting period. The full fair value of the cash settled award was ~~$1.1~~$1.6 million as of September 30, ~~2019~~2020 and is being recognized ratably as the underlying service period is provided.

The following table provides a reconciliation of liabilities measured at fair value using significant unobservable inputs (Level 3) for the nine months ended September 30, ~~2019~~2020 (in thousands):

During the nine months ended September 30, 2019, the Company achieved the second of the two milestones which was settled through the issuance of 886,843 shares of the Company’s common stock. See Note 8 for further information.

In ~~February 2016,~~November 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ~~2016-02, Leases~~2019-08, Compensation—Stock Compensation (Topic ~~842)~~718) and Revenue from Contracts with Customers (Topic 606), which ~~changes several aspects of~~clarifies that an entity must measure and classify share-based payment awards granted to a customer by applying the ~~accounting for leases, including the requirement that all leases with durations greater than twelve months be recognized on the balance sheet. The~~ guidance in Topic 718.

~~In March 2019, the Company closed on an expanded credit facility with Squadron for up to $30 million in additional secured financing.~~ ~~This additional financing has been made available under the Company’s existing credit facility with Squadron.~~ The Company accounted for the amendment as a debt modification with continued amortization of the existing and inclusion of the new debt issuance costs of $0.3 million amortized into interest expense utilizing the effective interest rate method. The Company took a draw of $10.0 million of the expanded credit facility in June 2019 to be used for general corporate purposes.

All or a portion of the PPP Loan may be forgiven by the SBA upon application. The Company submitted its application for forgiveness of the loan in November 2020. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs, covered rent payments, covered mortgage interest and covered utilities during the twenty-four-week period, beginning on the date of loan approval. For purposes of the CARES Act, payroll costs exclude compensation of an individual employee in excess of $100,000, prorated annually. Not more than 25% of the forgiven amount may be for non-payroll costs. Forgiveness is reduced if full-time headcount declines, or if salaries and wages for employees with salaries of $100,000 or less annually are reduced by more than 25%. In the event the PPP Loan, or any portion thereof, is forgiven pursuant to the PPP, the amount forgiven is applied to outstanding principal.

On December 4, 2019, the Company entered into a lease agreement for a new headquarters location which will consist of 121,541 square feet of office, engineering, and research and development space in Carlsbad, California.

The Company leases its buildings and certain equipment under operating leases which expire on various dates through 2021. Upon the Company’s adoption of ASU 2016-02, Leases (Topic 842) (“ASC ~~842~~842”), as of January 1, 2019 the Company recognized a ROU asset and ~~lease~~ liability for its building lease, assuming a 10.5% discount rate. Any short-term leases defined as 12twelve months or less or month-to-month leases were excluded and continue to be expensed each month. Total costs associated with these leases for the three and nine months ended September 30, ~~2019 was~~2020 were immaterial.

The Company determines if an arrangement is a lease at inception. The Company has operating leases for its buildings and certain equipment with lease terms of one year to 5.5 years, some of which include options to extend and/or terminate the lease. The exercise of lease renewal options is at the Company’s sole discretion and were not included in the calculation of the Company’s lease liability as the Company is not able to determine without uncertainty if the renewal option will be exercised. The depreciable life of assets and leasehold improvements are limited to the expected term unless there is a transfer of title or purchase option reasonably certain of exercise. The Company’s lease agreements do not contain any variable lease payments, residual value guarantees or any restrictive covenants.

The Company’s ROU asset represents the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date of the lease or the ASC 842 adoption date, whichever is later, based on the present value of lease payments over the lease term. When readily determinable, the Company uses the implicit rate in determining the present value of lease payments, or 10.5% as of the adoption date. When leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date or adoption date, including the lease term. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Future minimum annual lease payments under such leases are as follows as of September 30, ~~2019~~2020 (in thousands):

As of September 30, ~~2019,~~2020, the Company’s average remaining lease term is ~~1.9~~1.2 years.

The Company entered into a distribution agreement with a third-party provider in January 2020 in which the Company is obligated to certain minimum purchase requirements related to inventory and equipment leases. As of September 30, 2020, the minimum purchase commitment required by the Company under the agreement was $3.5 million to be paid over a three-year period. The Company also recognized a ROU asset related to the leased assets within the purchase agreement in the amount of $0.5 million for the nine months ended September 30, 2020. The ROU asset is being amortized into rent expense through the lease term. An immaterial amount of rent expense pertaining to these assets was recognized for the three and nine months ended September 30, 2020.

The Company is and may become involved in various legal proceedings arising from its business activities. While management is not aware of any litigation matter that in and of itself would have a material adverse impact on the Company’s consolidated results of operations, cash flows or financial position, litigation is inherently unpredictable, and depending on the nature and timing of a proceeding, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows or financial position in a particular period. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual or disclosure in the Company’s ~~consolidated~~ financial statements. An estimated loss contingency is accrued in the Company’s ~~consolidated~~ financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against the Company may be unsupported, exaggerated, or unrelated to reasonably possible outcomes, and as such are not meaningful indicators of the Company’s potential liability.

OnIn February ~~13,~~ 2018, NuVasive, Inc. filed suit against the Company in the United States District Court for the Southern District of California (~~NuVasive,~~(NuVasive, Inc. v.

In July 2020, the PTAB ruled that all challenged claims of the ‘156 Patent were valid (not unpatentable) and ruled that several challenged claims of the ‘334 Patent were invalid, while finding that other challenged claims of the ‘334 Patent were valid. NuVasive and the Company have both appealed the PTAB’s written decision on the matter. The ~~Company expects PTAB to issue its final decisions regarding~~appeals are currently pending before the U.S. Court of Appeals for the Federal Circuit. No briefing or hearing schedule has been set.

In January 2020, NuVasive filed a Motion for Partial Summary Judgment of infringement and validity of ~~these~~the ’832, ’780 and ’270 Patents and the Company filed a Motion for Summary Judgment of non-infringement of all asserted claims inand of invalidity of the ~~second half~~’832 Patent and for dismissal of ~~2020.

Trial ~~has been set for April 27, 2020.~~is scheduled to take place in June 2021.

The Company believes that the allegations lack merit and intends to vigorously defend all claims asserted. A liability is recorded in the ~~consolidated~~ financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. It is impossible at this time to assess whether the outcome of this proceeding will have a material adverse effect on the Company’s condensed consolidated results of operations, cash flows or financial position. Therefore, in accordance with authoritative accounting guidance, the Company has not recorded any accrual for a contingent liability associated with this legal proceeding based on its belief that a liability, while possible, is not probable and any range of potential future charge cannot be reasonably estimated at this time.

In the normal course of business, the Company enters into agreements under which it occasionally indemnifies ~~third-parties~~third parties for intellectual property infringement claims or claims arising from breaches of contract, representations or warranties. In addition, from time to time, the Company provides indemnity protection to ~~third-parties~~third parties for claims relating to past performance arising from undisclosed liabilities, product liabilities, environmental obligations, representations and warranties, and other claims. In these agreements, the scope and amount of remedy, or the period in which claims can be made, may be limited. It is not possible to determine the maximum potential amount of future payments, if any, due under these indemnities due to the conditional nature of the obligations and the unique facts and circumstances involved in each agreement.

In October 2017, NuVasive filed a lawsuit in Delaware Chancery Court against Mr. Miles, the Company’s Chairman and CEO, who was a former officer and board member of NuVasive. The Company itself was not initially a named defendant in this lawsuit; however, onin June ~~28,~~ 2018, NuVasive amended its complaint to add the Company as a defendant. As of September 30, ~~2019,~~2020, the Company has ~~not~~0t recorded any liability on the condensed consolidated balance sheet related to this matter. OnIn October ~~12,~~ 2018, the Delaware Court ordered that NuVasive begin advancing a portion of the legal fees for Mr. Miles’ defense in the lawsuit, as well as Mr. Miles’ legal fees incurred in pursuing advancement of his fees, pursuant to an indemnification agreement between NuVasive and Mr. Miles.

The Company has entered into various intellectual property agreements requiring the payment of royalties based on the sale of products that utilize such intellectual property.

HealthpointCapital, LLC, John H. Foster and Mortimer Berkowitz III and, in the event of a default, will be entered and enforced against these entities and/or individuals in that order. In September 2014, the Company and HealthpointCapital entered into an agreement for joint payment of settlement whereby HealthpointCapital has agreed to contribute $5 $5.0 million to the ~~$49~~$49.0 million settlement amount. In October 2020, HealthpointCapital began its $5.0 million contribution, which will be in the form of 5 quarterly payments. The $5$5.0 million is classified within stockholders’ equity on the Company’s condensed consolidated balance sheet

dueto the related party nature with HealthpointCapital and its affiliates. Payments made by HealthpointCapital will be recorded as a reduction to stockholder’s equity. See Note 1211 for further information.

As of September 30, ~~2019,~~2020, the Company has made installment payments in the aggregate of ~~$39.5~~$43.9 million, with a remaining outstanding balance of ~~$18.3~~$13.9 million (including interest). The Company has the right to prepay the amounts due without penalty. In addition, the unpaid balance of the amounts due accrues interest at the rate of 7% per year until paid in full. The accrued but unpaid interest will be paid in quarterly installments of $1.1 million (or the full amount of the accrued but unpaid interest if less than $1.1 million) following the full payment of the $31.5 million in quarterly installments described above. No interest will accrue on the accrued interest. The Settlement Agreement provides for mutual releases of all claims in the Orthotec, LLC v. Surgiview, S.A.S, et al. matter in the Superior Court of California, Los Angeles County and all other related litigation matters involving the Company and its directors and affiliates.

A reconciliation of the total net settlement obligation is as follows (in thousands):

~~On March 9, 2018, the Company acquired SafeOp, a~~ privately-held provider of neuromonitoring technology designed to enable effective intra-operative nerve health assessment. At the time of the acquisition, SafeOp had FDA 510(k) approval for a somatosensory evoked potential (“SSEP”) monitoring technology. The Company has developed a product that will allow for both free run and triggered specific recording of muscle activity, also known as Electromyography (“EMG”). The Company received FDA clearance for SafeOp’s EMG technology in February 2019 to complement the SSEP solution, and anticipates commercialization of the combined technology solution in mid-2019. In addition to expanding the Company’s market presence in lateral spine surgery, the Company believes that the SafeOp solution will allow it to integrate neuromonitoring into its broader product portfolio and accelerate the transition to procedural integration of the entire portfolio.

~~Under the term of the definitive merger agreement, the Company paid $15.1 million in cash and issued 3,265,132 shares of common stock.~~ The Company paid the full $15.1 million in cash consideration during the year ended December 31, 2018. On March 8, 2018, the Company issued 2,975,209 shares of common stock valued at $9.8 million, based on the closing share price of $3.30, and issued an additional 115,621 shares of common stock during the second quarter of 2018 and the remaining 174,302 during the third quarter of 2018.

In March 2018, the Company also issued $3 million in convertible notes that were convertible into a total of 987,578 shares of common stock, which included total interest incurred, and issued warrants to purchase 2.2 million shares of common stock at an exercise price of $3.50 per share and contain a five year life. The convertible notes matured on March 9, 2019 and were settled in cash. Upon maturity, the Company recognized the value associated with the beneficial conversion feature calculated at issuance of $0.2 million within interest expense on the Company’s condensed consolidated statement of operations for the nine months ended September 30, 2019. Shares of common stock were issued upon achievement of post-closing milestones as described further below. The warrants remain outstanding as of September 30, 2019.

The first of the two milestones was achieved during the year ended December 31, 2018 and resulted in the issuance of 443,421 shares of common stock as payment. The second milestone pertaining to regulatory approval was achieved and the Company issued 886,843 shares of common stock as payment during the three months ended March 31, 2019. Prior to achievement, the contingent consideration was recorded as a liability and measured at fair value using a probability-weighted income approach, utilizing significant unobservable inputs including the probability of achieving each of the potential milestones and an estimated discount rate related to the risks of the expected cash flows attributable to the milestones. The fair value of the contingent consideration, and the associated liability relating to the contingent consideration at each reporting date, was re-assessed with the changes in fair value reflected in earnings. For the nine months ended September 30, 2019, the fair value for the contingent consideration increased by $0.3 million due to the proximity of the achievement of the milestone. The amount was recorded within research and development expense on the condensed consolidated statement of operations and a corresponding increase in the liability on the Company’s condensed consolidated balance sheet. The full liability was relieved upon achievement of the remaining milestone during the period.

Basic earnings per share (“EPS”) is calculated by dividing the net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period and the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, common stock subject to repurchase by the Company, convertible preferred stock, options, convertible notes and warrants are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive.

The following table presents the computation of basic and diluted net loss per share for continuing and discontinued operations (in thousands, except per share amounts):

The anti-dilutive securities not included in diluted net loss per share were as follows (in thousands):

On ~~October 25, 2018,~~June 17, 2020, the Company’s ~~Board of Directors adopted~~shareholders approved an amendment to the Company’s 2016 Equity Incentive Award Plan, which increased the ~~maximum aggregate number~~shares of Common Stock available for issuance under the Equity Plan by 7,000,000 shares. At September 30, 2020, 4,285,924 shares of common stock remained available for issuance under the 2016 Equity Incentive Award Plan.

On April 5, 2020, the Company implemented a voluntary salary-to-equity conversion program for certain employees whose annual payroll costs exceed $100,000, including the Company’s executive officers. The program permitted each participant to make a voluntary election to reduce the participant’s compensation rate through July 11, 2020 from 10% to 75%. In exchange for the compensation reduction, each participant was granted a restricted stock unit from the Company’s 2016 Equity Incentive Plan, equal to the dollar amount of compensation reduction divided by the 30-day volume weighted average price of the Company’s common stock as of close of market on April 3, 2020. The restricted stock units granted under the program fully vested on July 10, 2020. The temporary reduction in compensation to the participants shall not be treated as a reduction in base annual salary rate for purposes of any other benefits plans in which the participants are enrolled or eligible to participate, including in any bonus plans of the Company. As the plan allows for a cash payment of the deferred amount in the event the employee separated from the Company prior to the completion date of the program, the amounts were recorded as a liability instrument through its settlement date with ~~respect to one or more~~a corresponding fair value update at each reporting period. The full fair value of $0.9 million was reclassified into equity upon settlement of the program and issuance of the common stock. A stock ~~rights that may be granted to any one person during any fiscal year from 500,000 to 1,250,000.~~compensation charge of $0.1 million and $0.9 million is recorded for the three and nine months ended September 30, 2020, respectively.

As further described in Note 5, during the year ended December 31, 2018, in connection with the initial debt financing with Squadron, the Company issued warrants to purchase 845,000 shares of common stock at an exercise price of $3.15 per share. An additional 4,838,710 warrants were issued at an exercise price of $2.17 per share during the second quarter of 2019, in conjunction with the Company’s draw on the expanded credit ~~facility~~facility. In May 2020, an additional 1,075,820 warrants were issued at an exercise price of $4.88 per share in conjunction with the Company’s second amendment to the Squadron debt for total warrants outstanding to Squadron of ~~5,683,710.~~6,759,530. The warrants have a seven-year term and are immediately exercisable. Further in conjunction with the second amendment, the termination dates for all existing Squadron warrants was extended to May 29, 2027 in order to align all warrant expiration dates. In accordance with authoritative accounting guidance, the warrants ~~classified~~qualified for equity treatment upon issuance and ~~the portion allocated to the outstanding debt~~ were recorded as a debt discount to the face of the debt liability based on fair value to be amortized into interest expense over the life of the debt agreement. The fair value assigned to the warrant amendment was also allocated as a debt issuance cost and amortized into interest expense. As the warrants provide for partial price protection that allow for a reduction in the price in the event of a lower per share priced issuance, the warrants were valued utilizing a Monte Carlo simulation that considers the probabilities of future financings. The Monte Carlo model simulates the present value of the potential outcomes of future stock prices of the Company over the seven-year life of the warrants. The projection of stock prices is based on the risk-free rate of return and the volatility of the stock price of the Company and correlates future equity raises based on the probabilities provided.

To calculate its interim tax provision, at the end of each interim period the Company estimates the annual effective tax rate and applies that to its ordinary quarterly earnings. In addition, the effect of changes in enacted tax laws or rates or tax status is recognized in the interim period in which the change occurs. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in foreign jurisdictions, permanent and temporary differences between book and tax amounts, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or the tax environment changes.

Intraperiod tax allocation rules require the Company to allocate the provision for income taxes between continuing operations and other categories of earnings, such as discontinued operations. In periods in which the Company has a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as discontinued operations, the Company must allocate the tax provision to the other categories of earnings, and then record a related tax benefit in continuing operations.

The unrecognized tax benefits at September 30, ~~2019~~2020 and December 31, ~~2018~~2019 were ~~$4.4~~$2.5 million for both periods, with no0 changes occurring during the year-to-date period.

The Company’s effective tax rate ~~of (0.21)% for the nine months ended September 30, 2019~~ differs from the federal statutory rate of 21% primarily due to the ~~Company being in a~~Company’s net loss position.

At December 31, 2019, the Company had federal and state net operating loss carryforwards of $205.2 million and $128.2 million, respectively, expiring at various dates beginning in 2019 and continuing through 2039. Net operating losses generated in years ending after December 31, 2017 can be carried forward indefinitely for federal and some state taxes. At December 31, 2019, the Company had state research and development tax credit carryforwards of $3.2 million. The state research and development tax credits do not have an expiration date and may be carried forward indefinitely.

Utilization of the net operating loss and tax credit carryforwards may become subject to annual limitations due to ownership change limitations that could occur in the future as provided by Section 382 and 383 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. These ownership changes may limit the amount of the net operating loss and tax credit carryforwards that can be utilized annually to offset future taxable income, if the Company experiences a cumulative change in ownership of more than 50% within a three-year testing period.

In July 2016, the Company entered into a forbearance agreement with HealthpointCapital, LLC, HealthpointCapital Partners, L.P., and HealthpointCapital Partners II, L.P. (collectively, "HealthpointCapital"), pursuant to which HealthpointCapital, on behalf of the Company, paid $1.0 million of the $1.1 million payment due and payable by the Company to Orthotec on July 1, 2016 and agreed to not exercise its contractual rights to seek an immediate repayment of such amount. Pursuant to this forbearance agreement, the Company repaid this amount in September 2016. The Company and HealthpointCapital also entered into an agreement for joint payment of settlement whereby HealthpointCapital has agreed to contribute $5$5.0 million to the ~~$49~~$49.0 million Orthotec settlement amount.In October 2020, HealthpointCapital began its $5.0 million contribution, which will be in the form of 5 quarterly payments.

During the second quarter of 2018, HealthpointCapital Partners, L.P., and HealthpointCapital Partners II, L.P. distributed its holdings in the Company’s common stock to its limited partners. As a result, the fund is no longer a shareholder of the Company as of September 30, ~~2019~~2020. The $5$5.0 million receivable from HealthpointCapital, LLC continues to be classified within stockholders’ equity on the Company’s condensed consolidated balance ~~sheet~~sheets due to the related party nature with HealthpointCapital affiliates.

We are a medical technology company focused on the design, development, and advancement of technology for better surgical treatment of spinal disorders. We are dedicated to revolutionizing the approach to spine surgery. We have a broad product portfolio designed to address the majority of ~~the~~ U.S. market for fusion-based spinal disorder solutions. We intend to drive growth by exploiting our collective spine experience and investing in the research and development to continually differentiate our solutions and improve spine surgery. We believe our future success will be fueled by introducing market-shifting innovation to the spine market, and ~~we believe~~ that we are well-positioned to capitalize on current spine market dynamics.

We market and sell our products in the U.S. through a network of independent distributors and direct sales representatives. An objective of our leadership team is to deliver increasingly consistent, predictable growth. To accomplish this, we have partnered more closely with new and existing distributors to create a more dedicated and loyal sales channel for the future. We have added, and intend to continue to add, new high-quality dedicated distributors to expand future growth. We believe this will allow us to reach an untapped market of surgeons, hospitals, and national accounts across the U.S., as well as better penetrate existing accounts and territories.

We have ~~made significant~~continued to make progress in the transition of our sales channel since early 2017, driving the percent of sales contributed by our strategic distribution channel from approximately ~~84% and 79% for the three and nine months ended September 30, 2018, respectively, to~~ 89% and 87% for the three and nine months ended September 30, 2019 to 92% and 91% for the three and nine months ended September 30, 2020, respectively. ~~Going forward, we~~We intend to continue to relentlessly drive toward a fully exclusive network of independent and direct sales agents. ~~Recent consolidation in~~Consolidation within the industry is ~~facilitating~~helping facilitate the process, as large, seasoned agents ~~are seeking~~continue to seek opportunities to re-enter the spine market by partnering with spine-focused companies that have broad, growing product portfolios.

On ~~August 2, 2019,~~October 16, 2020, we closed an underwritten public offering (the “Offering”) of a total of ~~12,535,000~~13,142,855 shares of our common stock. The shares were sold pursuant to a ~~purchase~~underwriting agreement dated ~~July 31, 2019~~October 13, 2020 (the ~~“Purchase~~“Underwriting Agreement”), between usthe Company and ~~Piper Jaffray~~Morgan Stanley & Co., LLC and Cowen and Company, LLC, as representative of the several underwriters named therein, at a price to the public of ~~$4.60~~$8.75 per share. The closing of the Offering included the issuance and sale of ~~1,635,000~~1,714,285 shares of our common stock, included within the total number of shares above, pursuant to the full exercise of the underwriters’ option to purchase additional shares pursuant to the ~~Purchase~~Underwriting Agreement. The net proceeds ~~to us~~ from the Offering were approximately ~~$54.0~~$107.7 million, including the net proceeds from the ~~option shares.~~overallotment shares and deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Prior to the spread of COVID-19, we experienced year-over-year U.S. sales growth of over 30%, which was consistent with previously issued revenue guidance in January 2020. As the COVID-19 pandemic spread to Western Europe and the U.S., we experienced a significant decline in procedures from the last half of March 2020 through the month of April. During May procedure volumes began to increase and in the month of June sales and procedure volumes returned to near pre-pandemic levels.

The depth and extent to which the COVID-19 pandemic will impact individual markets continues to vary. We ~~intend~~expect procedure volumes to ~~use~~remain difficult to estimate as COVID-19 infections continue to spread and may cause additional strain on hospital resources and deferral of elective procedures.

Capital markets and worldwide economies have also been significantly impacted by the ~~net proceeds~~COVID-19 pandemic, and it is possible that this could cause a local and/or global economic recession. Such economic recession could have a material adverse effect on our long-term business as hospitals curtail and reduce capital and overall spending. The COVID-19 pandemic and local actions, such as “shelter-in-place” orders and restrictions on our ability to travel and access our customers or temporary closures of the ~~Offering for general corporate purposes, including working capital, capital expenditures~~facilities of our suppliers and ~~continued research~~their contract manufacturers, could further significantly impact our sales and ~~development with respect~~our ability to ship our products and ~~technologies.

Any of these events could negatively impact the ~~net proceeds~~number of ~~the Offering may also be used to fund possible investments in~~procedures performed and have a material adverse effect on our business, financial condition, results of operations, or ~~acquisitions of complementary businesses, products, or technologies.~~

On September 1, 2016, we completed the sale of our international distribution operations and agreements, including our wholly-owned subsidiaries in Japan, Brazil, Australia, China and Singapore and substantially all of the assets of our other sales operations in the United Kingdom and Italy (“International Business”), to an affiliate of Globus (“Globus Transaction”). Following the closing of the Globus Transaction, we now operate in the U.S. market only and are restricted from marketing and selling our products in foreign markets pursuant to the terms and conditions, and for the time periods, set forth in the definitive documents related to the Globus Transaction.cash flows.

The following is a description of the primary components of our ~~revenues~~revenue and expenses:

~~Revenues~~Revenue. We derive our ~~revenues~~revenue primarily from the sale of spinal surgery implants used in the treatment of spine disorders. Spinal implant products include pedicle screws and complementary implants, interbody devices, plates, and tissue-based materials. Our ~~revenues are~~revenue is generated by our direct sales force and independent distributors. Our products are requested directly by surgeons and shipped and billed to hospitals and surgical centers. Currently, most of our business is conducted with customers within markets in

which we have experience and with payment terms that are customary to our business. We may defer ~~revenues~~revenue until the time of collection if circumstances related to payment terms, regional market risk or customer history indicate that collectability is not certain.

Cost of ~~revenues~~revenue. Cost of ~~revenues~~revenue consists of direct product costs, royalties, milestones and the amortization of purchased intangibles. Our product costs consist primarily of direct labor, overhead, and raw materials and components. The product costs of certain of our biologics products include the cost of procuring and processing human tissue. We incur royalties related to the technologies that we license from others and the products that are developed in part by surgeons with whom we collaborate in the product development process. Amortization of purchased intangibles consists of amortization of developed product technology.

Research and development ~~expense~~expenses also ~~includes~~include salaries and related employee benefits, research-related overhead expenses, fees paid to external service providers in both cash and equity, and costs associated with our Scientific Advisory Board and Executive Surgeon Panels.

Sales, general and administrative expenses. Sales, general and administrative ~~expense consists~~expenses consist primarily of salaries and related employee benefits, sales commissions and support costs, depreciation of our surgical instruments, regulatory affairs, quality assurance costs, professional service fees, travel, medical education, trade show and marketing costs, insurance and legal expenses.

~~Transaction related~~Transaction-related (credits) expenses. ~~Reflects~~Transaction-related (credits) expenses reflect the recognition of transaction expenses incurred as part of the ~~SafeOp acquisition.~~

~~Gain on settlement.~~ ~~Gain on settlement consists of a gain of approximately $6.2 million for~~terminated tender offer related to the year ended December 31, 2018 as a result of the settlement agreement with Elite Medical Holdings and Pac 3 Surgical, pursuant to which we made a cash payment of $0.4 million as the final and total compensation under the collaboration and related amendment. The gain reflects the reversal of accrued obligations previously recorded under the collaboration. EOS transaction.

Restructuring expenses. Restructuring ~~expense consists~~expenses consist of severance, social plan benefits and related taxes in connection with our ~~ongoing~~historical cost rationalization ~~efforts, including~~efforts.

Income tax benefit. Income tax benefit from continuing operations primarily consists of release of the valuation allowance from the SafeOp acquisition, partially offset by state taxes.

Our discussion and analysis of our financial condition and results of operations is based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. On an on-going basis, we evaluate our estimates and assumptions, including those related to revenue recognition, allowances for accounts receivable, inventories and intangible assets, stock-based compensation and income taxes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumption conditions.

Critical accounting policies are those that, in management’s view, are most important in the portrayal of our financial condition and results of operations. Aside from ~~newly implemented accounting policies related to revenues discussed below and for~~ the changes disclosed in Note 2 to the Notes to Condensed Consolidated Financial Statements included in Item 1, Part I of this Quarterly Report on Form 10-Q, management believes there have been no material changes during the three ~~and nine~~ months ended September 30, ~~2019~~2020 to the critical accounting policies discussed in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 filed with the SEC on March ~~29, 2019.~~

Effective January 1, 2019, we adopted ASC No. 2016‑02, Leases (Topic 842) (“ASU 2016‑02” or “ASC 842”), which supersedes the current accounting for leases, using the modified retrospective transition method. The Company has elected to apply the practical expedients allowed by the standard for existing leases. The new standard, while retaining two distinct types of leases, finance and operating, (i) requires lessees to record a right-of-use asset and a related liability for the rights and obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar to current accounting, (ii) eliminates current real estate specific lease provisions, (iii) modifies the lease classification criteria and (iv) aligns many of the underlying lessor model principles with those in the new revenue standard. We determined the initial classification and measurement of its right-of-use assets and lease liabilities at the lease commencement date, or the adoption date, if later, and thereafter if modified. We recognized a

right-of-use asset for our operating leases with lease terms greater than 12 months. The lease term includes any renewal options and termination options that we are reasonably assured to exercise. The present value of lease payments is determined by using the incremental borrowing rate for operating leases determined by using the incremental borrowing rate of interest that we would pay to borrow on a collateralized basis an amount equal to the lease payments in a similar economic environment. We applied the new guidance to our existing facility lease at the time of adoption and recognized a right-of-use asset of $2.4 million and operating lease liability of $2.9 million, during the first period of adoption, and recorded a reversal of the previous deferred rent balance under the previous lease guidance of approximately $0.6 million. We entered into another facility lease for smaller office space during the third quarter of 2019 and also applied this guidance to create an additional ROU asset and operating lease liability. The two leases are presented together on the Company’s condensed consolidated balance sheet.

The tables below set forth certain statements of operations data for the periods indicated (in thousands). Our historical results are not necessarily indicative of the operating results that may be expected in the future.

~~Gain on settlement.~~ In February 2018, we reached a settlement agreement with Elite Medical Holdings and Pac 3 Surgical, pursuant to which we made a cash payment of $0.4 million as the final and total compensation under a collaboration agreement and related amendment between the Company and these third parties. In addition, the parties agreed to release each other and waive any and all rights and claims arising from the collaboration agreement and amendment. We recorded a gain of approximately $6.2 million for the nine months ended September 30, 2018, reflecting the reversal of accrued obligations previously recorded under the collaboration agreement.

~~Restructuring expense~~. Restructuring expense was $0.0 million for the three months ended September 30, 2019 compared to $0.2 million for the three months ended September 30, 2018 and $0.1 million for the nine months ended September 30, 2019 compared to $0.8 million for the nine months ended September 30, 2018. Beginning in late 2016 with the sale of our international business to Globus and continuing in 2018, we began a corporate initiative to rationalize our cost structure in line with our reduced operations and implemented a strategic repositioning of the Company, including the changeover of our senior leadership team, and have incurred related restructuring costs consisting primarily of severanceTotal interest and other ~~personnel charges.~~

Total interest and other expense, net increased ~~$1.8~~$3.2 million during the nine months ended September 30, ~~2019~~2020 as compared to the nine months ended September 30, ~~2018~~2019, primarily due to interest expense on new debt arrangements, additional draws on existing agreements and a loss on debt extinguishment related to the payoff of the MidCap facility in the second quarter of 2020.

Income tax provision. Income tax provision for the three and nine months ended September 30, 2020, was negligible and remained consistent as compared to the three and nine months ended September 30, 2019. For the three and nine months ended September 30, 2020, we had an effective income tax rate of 0%, primarily due to our ~~new debt arrangements.~~

~~Income tax provision (benefit)~~. The 2018 income tax benefit from continuing operations primarily consists of the release of the valuation allowance related to the SafeOp acquisition, partially offset by state taxes. ASC 740-20 requires total income tax expense or benefit to be allocated among continuing operations, discontinued operations, extraordinary items, other comprehensive income and items charged directly to shareholders’ equity. This allocation is referred to as intra-period tax allocation. Accordingly, we are required to allocate the provision or benefit for income taxes between continuing operations and discontinued operations. net loss position.

On October 16, 2020, we closed the Offering in which we issued and ~~unless and until it does, we will continue~~sold a total 13,142,855 shares of our common stock, including overallotment shares, at a price to ~~need to raise additional capital. At September 30, 2019, our principal sources~~the public of ~~liquidity consisted of cash of~~ ~~$57.8 million~~ ~~and accounts receivable (net) of $15.4 million, which includes the~~$8.75 per share. The net proceeds ~~of $54.0 million received in August 2019~~to us from the Offering were approximately $107.7 million. Our working capital at September 30, 2020 was $38.5 million (including cash of $15.7 million) which, along with ~~available draws on our working capital credit line with MidCap, allows us~~proceeds from the Offering, we expect to be able to fund our operations through at least one year subsequent to the date the condensed consolidated financial statements are issued. We also have available an additional $20 million under the Expanded Credit Facility with Squadron Medical Finance Solutions LLC (“Squadron”), which can be drawn down any time on or before December 31, 2020, if and when needed.

Historically, our principal sources of cash have included customer payments from the sale of our products, proceeds from the issuance of common and preferred stock and proceeds from the issuance of debt. Our principal uses of cash have included cash used in operations, payments relating to purchases of surgical instruments, repayments of borrowings under the Amended Credit Facility, payments due under the Orthotec settlement agreement and acquisitions of businesses and intellectual property rights. We expect that our principal uses of cash in the future will be similar. We expect that, as our revenues grow, our sales and marketing, research and development expenses and our capital expenditures will continue to grow and, as a result, we will need to generate significant net revenues to achieve profitability. We expect operating losses and negative cash flows to continue for at least the next year as we continue to incur costs related to the execution of our operating plan and introduction of new products.

On August 2, 2019, we closed the Offering in which we issued and sold a total 12,535,000 shares of our common stock, at a price to the public of $4.60 per Share. The net proceeds to us from the Offering were approximately $54.0 million, including the net proceeds from the option shares.

On March 27, 2019, we closed on an expanded credit facility with Squadron for up to $30 million in additional secured financing. This additional financing is provided under our existing credit facility with Squadron. In June 2019, we took a draw of $10 million on the expanded credit facility to be used for general corporate purposes. The additional borrowings under the credit facility will mature concurrent with the current secured financing from Squadron and bear interest at LIBOR plus 8% per annum, subject to a 10% floor and a 13% ceiling. Interest-only payments are due monthly through May 2021, followed by principal payable in 29 equal monthly installments beginning June 2021 and a lump-sum payment payable at maturity in November 2023. I~~n conjunction with~~ the first draw under the expanded credit facility, we issued to Squadron warrants to purchase 4,838,710 shares of our common stock at an exercise price of $2.17 per share. The warrants have a seven-year term and are immediately exercisable. No additional warrants are due upon future draws.

We may seek additional funds from public and private equity or debt financings, borrowings under new or existing debt facilities or other sources to fund our projected operating requirements. However, there is no guarantee that we will be able to obtain further financing, or do so on reasonable terms. If we are unable to raise additional funds on a timely basis, or at all, we would be materially adversely affected. As more fully described below, our debt agreements include traditional lending and reporting covenants, including a financial covenant that requires us to maintain a minimum fixed charge coverage ratio beginning in April 2020 and a minimum liquidity covenant of $5.0 million effective through March 2020. Should at any time we fail to maintain compliance with these covenants, we will need to seek waivers or amendments to the debt agreements. If we are unable to secure such waivers or amendments, we may be required to classify our obligations under the debt agreements in current liabilities on our condensed

consolidated balance sheet. We may also be required to repay all or a portion of outstanding indebtedness under the debt agreements, which would require us to obtain further financing. We were in compliance with the covenants under the credit agreement at September 30, 2019.

A substantial portion of our available cash funds is held in business accounts with reputable financial institutions. At times, however, our deposits may exceed federally insured limits and thus we may face losses in the event of insolvency of any of the financial institutions where our funds are deposited. We did not hold any marketable securities as of September 30, 2019.

~~Amended Credit Facility,~~ Squadron Credit Agreement, Paycheck Protection Loan and Other Debt

~~Our Amended Credit Facility with MidCap provides for a revolving credit commitment up to $22.5 million. As of September 30, 2019, $11.6 million was outstanding under the revolving line of credit.~~

The revolving line of credit accrues interest at LIBOR plus 6.0%, reset monthly. At September 30, 2019, the revolving line of credit carried an interest rate of 8.10%. The borrowing base is determined based on the value of domestic eligible accounts receivable. As collateral for the Amended Credit Facility, MidCap has a first lien security interest in accounts receivable and a second lien on substantially all other assets. The Amended Credit Facility also includes several event of default provisions, such as payment default, insolvency conditions and a material adverse effect clause, which could cause interest to be charged at a rate which is up to five percentage points above the rate effective immediately before the event of default or result in MidCap’s right to declare all outstanding obligations immediately due and payable.

On September 1, 2016, we entered into the Globus facility, pursuant to which Globus agreed to loan us up to $30 million. We made an initial draw of $25 million under the Globus facility with an additional draw of $5 million made in the fourth quarter of 2016. In November 2018, the $29.2 million outstanding was paid in full.Commitments

The debt with Globus noted above. In addition, in June 2019, we took a draw of $10 million from our total available $30 million expanded credit facility with Squadron. The total debt outstanding with Squadron has a five-year maturity and bears interest at LIBOR plus 8% ~~(10.1%~~(10.0% as of September 30, ~~2019)~~2020) per annum. The credit agreement specifies a minimum interest rate of ~~10%~~10.0% and a maximum of ~~13%~~13.0% per year. ~~Interest-only~~In March 2019, we expanded the credit facility with Squadron for up to an additional $30.0 million in secured financing. We took a draw of $10.0 million of the expanded credit facility in June 2019 and, subsequently, took a draw of the remaining $20.0 million in April 2020. On May 29, 2020, we entered into a second amendment to the Term Loan to expand the credit facility by an additional $35.0 million and remove all financial covenant requirements. It is at our sole discretion to make draws on the additional $35.0 million Term Loan. In June 2020, we took a draw of $10.0 million used to retire the existing working capital revolver with MidCap. All future draws must be made by December 31, 2021. The total principal outstanding under the Term Loan as of September 30, 2020 is $75.0 million with an additional $25.0 million in available borrowings. Under the terms of the amended facility, the maturity date on the entire term loan was extended to June 2025 with interest-only payments ~~are~~ due monthly through ~~May 2021,~~November 2022, followed by ~~$10~~monthly principal payments of $1.0 million ~~in principal payable in 29 equal monthly installments~~ beginning ~~June 2021~~December 2022 and a ~~$25 million~~ lump-sum payment payable at maturity in ~~November 2023.~~June 2025.

On April 23, 2020, we received the proceeds from a loan in the amount of approximately $4.3 million (the “PPP Loan”) from Silicon Valley Bank, as lender, pursuant to the Paycheck Protection Program (“PPP”) of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The PPP Loan matures on April 21, 2022 and bears interest at a rate of 1.0% per annum. Commencing August 21, 2021, we are required to pay the lender equal monthly payments of principal and interest as required to fully amortize by April 21, 2022 the principal amount outstanding on the PPP Loan as of the date prescribed by guidance issued by the U.S. Small Business Administration (“SBA”). The PPP Loan is evidenced by a promissory note dated April 21, 2020, which contains customary events of default relating to, among other things, payment defaults and breaches of representations and warranties. We may prepay the PPP Loan at any time prior to maturity with no prepayment penalties.

All or a portion of the PPP Loan may be forgiven by the SBA upon application. We submitted our application for forgiveness of the loan in November 2020. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs, covered

rent payments, covered mortgage interest and covered utilities during the twenty-four-week period, beginning on the date of loan approval. For purposes of the CARES Act, payroll costs exclude compensation of an individual employee in excess of $100,000, prorated annually. Not more than 25% of the forgiven amount may be for non-payroll costs. Forgiveness is reduced if full-time headcount declines, or if salaries and wages for employees with salaries of $100,000 or less annually are reduced by more than 25%. In the event the PPP Loan, or any portion thereof, is forgiven pursuant to the PPP, the amount forgiven is applied to outstanding principal. We used all of the proceeds from the PPP Loan to retain employees and maintain payroll. Although we have applied for loan forgiveness as afforded by the PPP, we cannot provide assurance that such loan forgiveness will be granted in whole or in part.

We entered into an Inventory Financing Agreement whereby we may draw up to $3.0 million for the purchase of inventory to accrue interest at a rate of LIBOR plus 8% and also includes a 10% floor and 13% ceiling. All principal will become due and payable upon maturity on November 6, 2023 and all interest will be paid monthly. Should we elect to prepay the Squadron credit agreement, all amounts due under the Inventory Financing Agreement will become mandatorily due. Our obligation outstanding under the Inventory Financing Agreement as of September 30, 2020 was $3.0 million.

As of September 30, 2020, we have made $43.9 million in Orthotec settlement payments and there remains an aggregate amount of $13.9 million in Orthotec settlement payments (including accrued and future interest) to be paid by us.

We entered into a distribution agreement with a third-party provider in January 2020 in which we are obligated to certain minimum purchase requirements related to inventory and equipment leases. As of September 30, 2020, the minimum purchase commitment required by us under the agreement was $3.5 million to be paid over a three-year period.

Our various debt agreements include several event of default provisions, such as payment default, insolvency conditions and a material adverse effect clause, which could cause interest to be charged at a rate which is up to five percentage points above the rate effective immediately before the event of default or result in our lenders’ rights to declare all outstanding obligations immediately due and payable. Furthermore, the credit agreements contain various covenants, including various negative covenants including a $5 million minimum liquidity requirement through March 31, 2020. The minimum liquidity covenant will be replaced by a fixed charge ratio, pursuant to which operating cash to fixed charges (as defined) must equal at least 1:1 on a rolling 12-month basis, beginning April 2020.payable We were in compliance with the covenants under the credit agreements at September 30, ~~2019.~~

In January 2016, we entered into a lease agreement, ~~(the “Building Lease”)~~or the Building Lease, for office, engineering, and research and development space in Carlsbad, California with the lease term through July 31, 2021. Under the Building Lease our monthly rent payable is approximately $105,000 per month during the first year and increases by approximately $3,000 each year thereafter.

34On December 4, 2019, we entered into a new lease agreement, or new Building Lease, for a new headquarters location which will consist of 121,541 square feet of office, engineering, and research and development space in Carlsbad, California. The term of the new Building Lease is currently anticipated to commence November 15, 2020 and terminate November 30, 2030, subject to two sixty month options to renew. Base rent under the Building Lease for the first twelve months of the term will be $195,000 per month subject to full abatement during months two through ten. Base rent for the second year of the term will be $244,115 per month and thereafter will increase annually by 3%. At the beginning of each exercised option period, base rent will be adjusted to the market rental value, and thereafter will increase annually by 3% through the end of such option period.

Aside from newly implemented accounting policies related to leases discussed above under “Critical Accounting Policies and Estimates” and for the changes disclosed in Note 2 to the Notes to Condensed Consolidated Financial Statements (Unaudited) under the heading “Recent Accounting Pronouncements,” there have been no new accounting pronouncements or changes to accounting pronouncements during the ~~nine~~three months ended September 30, ~~2019,~~2020, as compared to the recent accounting pronouncements described in the Company's Annual Report on Form 10-K for the year ended December 31, ~~2018,~~2019, that was filed with the SEC on March ~~29, 2019.~~17, 2020.

This Quarterly Report on Form 10-Q incorporates a number of forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including statements regarding:

Any or all of our forward-looking statements in this Quarterly Report on Form 10-Q may turn out to be wrong. They can be affected by inaccurate assumptions and/or by known or unknown risks and uncertainties. Many factors mentioned in our discussion in this Quarterly Report on Form 10-Q will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially from expected results.

We also provide a cautionary discussion of risks and uncertainties under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 and any updates to those risk factors filed from time to time in our subsequent periodic and current reports filed with the SEC. These are factors that we think could cause our actual results to differ materially from expected results. Other factors besides those listed there could also adversely affect us.

Without limiting the foregoing, the words “believe,” “anticipate,” “plan,” “expect,” “estimate,” “may,” “will,” “should,” “could,” “would,” “seek,” “intend,” “continue,” “project,” and similar expressions are intended to identify forward-looking statements. There are a number of factors and uncertainties that could cause actual events or results to differ materially from those indicated by such forward-looking statements, many of which are beyond our control, including the factors set forth under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019 and any updates to those risk factors filed from time to time in our subsequent periodic and current reports filed with the SEC. In addition, the forward-looking statements contained herein represent our estimate only as of the date of this filing and should not be relied upon as representing our estimate as of any subsequent date. While we may elect to update these forward-looking statements at some point in the future, we specifically disclaim any obligation to do so to reflect actual results, changes in assumptions or changes in other factors affecting such forward-looking statements.

Other outstanding debt consists of ~~fixed~~various variable rate instruments, including debt outstanding under the ~~Amended Credit Facility~~Term Loan with ~~MidCap and the Globus Facility Agreement, notes payable and capital leases.~~Squadron.

Our borrowings under our credit facilities expose us to market risk related to changes in interest rates. As of September 30, ~~2019,~~2020, our outstanding floating rate indebtedness totaled ~~$58.9~~$79.3 million. The primary base interest rate is the LIBOR rate. Assuming the outstanding balance on our floating rate indebtedness remains constant over a year, a ~~100 basis~~100-basis point increase in the interest rate would decrease pre-tax income and cash flow by approximately ~~$0.6~~$0.8 million.

We purchase raw materials that are processed from commodities, such as titanium and stainless steel. These purchases expose us to fluctuations in commodity prices. Given the historical volatility of certain commodity prices, this exposure can impact our product costs. However, because our raw material prices comprise a small portion of our cost of ~~revenues,~~revenue, we have not experienced any material impact on our results of operations from changes in commodity prices. A 10% change in commodity prices would not have had a material impact on our results of operations for the three and nine months ended September 30, ~~2019.~~2020.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in our reports that we file or submit pursuant to the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s, or SEC's, rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Under the supervision and with ~~the~~ participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report. Based on ~~such~~this evaluation, our ~~management, including our~~Company’s Chief Executive Officer and Chief Financial Officer ~~has~~have concluded that our disclosure controls and procedures were ~~not~~ effective at athe reasonable ~~assurance~~ level of assurance.

~~This~~The material weakness related to athe lack of sufficient ~~oversight~~review over sales order and ~~review to ensure~~inventory transfers resulted in a reasonable possibility that a material misstatement of our revenue and inventory in the ~~complete and proper application of U.S. GAAP associated with complex equity transactions.~~annual or interim financial statements may not be prevented or detected on a timely basis. To remediate the ~~material weakness~~deficiencies described above and to prevent similar deficiencies in the future, we ~~added additional controls~~developed and ~~procedures, including:~~implemented a remediation plan during the first quarter of 2020 which included:

~~However, the material weakness~~deficiencies will not be considered fully remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. Any actions we have taken or may take to remediate these deficiencies are subject to continued management review supported by testing, as well as oversight by the Audit Committee of our Board of Directors.

Despite most of our employees working remotely due to the current COVID-19 pandemic, we have not experienced any material impact to our internal control over financial reporting. We will continue to monitor the COVID-19 situation to assess and minimize any impact on the design and operating effectiveness of our internal control over financial reporting.

We are and may become involved in various legal proceedings arising from our business activities. While the Company has no material accruals for pending litigation or claims for which accrual amounts are not disclosed in the Company’s condensed consolidated financial statements, litigation is inherently unpredictable, and depending on the nature and timing of a proceeding, an unfavorable resolution could materially affect our future consolidated results of operations, cash flows or financial position in a particular period. We assess contingencies to determine the degree of probability and range of possible loss for potential accrual or disclosure in our condensed consolidated financial statements. An estimated loss contingency is accrued in our condensed consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, we may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against us may be unsupported, exaggerated or unrelated to reasonably possible outcomes, and as such are not meaningful indicators of our potential liability.

Refer to Note 6to the Notes to Condensed Consolidated Financial Statements included in Item 1, Part I of this Quarterly Report on Form 10-Q for further information regarding the NuVasive, Inc. litigation.

There have been no material changes to the risk factors described under Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2018,~~2019, filed with the SEC on March ~~29, 2019.~~ 17, 2020 except for those noted below:

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, COVID-19 has spread to multiple countries, including the United States, and several European countries. To date, COVID-19 has had, and may continue to have, an adverse impact on our operations, supply chains, distribution channels and expenses as a result of the preventive and precautionary measures that we, our customers, other businesses, and governments are taking, including the deferral of elective medical procedures and diversion of capital and other resources. Due to these impacts and measures, we have experienced and may continue to experience significant and unpredictable reductions in the demand for our products as healthcare customers divert medical resources and priorities towards the treatment of the disease. For example, as COVID-19 reached a global pandemic level in the month of March 2020, we experienced significant decline in procedure volume in the U.S., as healthcare systems diverted resources to meet the increasing demands of managing COVID-19. In addition, the American College of Surgeons, U.S. surgeon general, and other public health bodies have recommended delaying elective surgeries during the COVID-19 pandemic, and surgeons and medical societies are evaluating the risks of minimally invasive surgeries in the presence of infectious diseases, which we expect will continue to negatively impact the usage of our products and procedures performed.

Due to the COVID-19 outbreak, we have experienced significant business disruptions, including restrictions on our ability to sell, distribute and service our products, temporary closures of our facilities and the facilities of our suppliers and their contract manufacturers, as well as reduction in access to our customers due to diverted resources and priorities and the business hours of hospitals as governments institute prolonged shelter-in-place and/or self-quarantine mandates. For example, our corporate headquarters located in California has instituted shelter-in-place orders applicable to our employees in that region. These unprecedented measures to slow the spread of the virus taken by local governments and health care authorities globally, including the deferral of elective medical procedures and social distancing measures, have had, and will continue to have, a significant negative impact on our operations and financial results.

As a result of the shelter-in-place orders implemented by state and local governments, we have instituted a remote work environment which has impacted our employees working at our California headquarters. The remote work environment makes us more susceptible to fraud, system interruptions and similar errors that from time to time result in lost funds or delayed transactions. To date, our email and computer systems have been subject to and are likely to continue to be the target of, fraudulent attacks, including attempts to cause us to improperly transfer funds or defraud our vendors into improperly transferring funds meant for us. These attacks have increased in frequency and sophistication. When a fraud is successfully perpetrated, funds transferred to a fraudulent recipient are often times not recoverable, and, in certain instances, we may be liable for those unrecovered funds. While we have greatly enhanced our automated and manual controls to mitigate this risk, there can be no assurance that such controls will prevent or detect such attempts, which may result in financial losses or other adverse consequences which could be material to us.

In addition, the COVID-19 pandemic has adversely affected, and may continue to adversely affect, the economies and financial markets of many countries, which may result in a period of regional, national, and global economic slowdown or regional, national, or global recessions that could curtail or delay spending by hospitals and affect demand for our products as well as increased risk of customer defaults or delays in payments. COVID-19 and the current financial, economic, and capital markets environment, and future developments in these and other areas present material uncertainty and risk with respect to our performance, financial condition, volume of business, results of operations, and cash flows. Due to the uncertain scope and duration of the pandemic and uncertain timing of global recovery and economic normalization, we are unable to estimate the impacts on our operations and financial results. As a result, we have withdrawn our full year 2020 financial and procedure guidance.

Our loans under the Paycheck Protection Program may not be forgiven or may subject us to challenges and investigations regarding our qualification for the loan.

On April 23, 2020, we received a PPP Loan under the PPP, which was established under the Coronavirus Aid, Relief and Economic Security Act, known as the CARES Act, in the aggregate principal amount of approximately $4.3 million. Pursuant to section 1106 of the CARES Act, we may apply for and be granted forgiveness for all or a portion of the PPP Loan. Such forgiveness will be determined, subject to limitations, based on the use of the loan proceeds for qualifying expenses, which include payroll costs, rent, and utility costs over the allowable measurements period following the receipt of the loan proceeds.

The SBA continues to develop and issue new and updated guidance regarding the PPP Loan application process, including guidance regarding required borrower certifications and requirements for forgiveness of loans made under the program. We continue to track the guidance as it is released and assess and re-assess various aspects of its application as necessary. However, given the evolving nature of the guidance and our anticipated ability to use the loan proceeds for qualifying expenses, we cannot give any assurance that our PPP Loan will be forgiven in whole or in part.

~~None.~~ On November 4, 2020, we entered into an Amended and Restated Warrant to Purchase Common Stock (the “Amended Warrant”) with Patrick S. Miles. The Amended Warrant amends the Warrant to Purchase Common Stock that was issued to Mr. Miles on December 28, 2017 in connection with his acquisition of shares of our common stock to permit net exercise of the Warrant via cashless exercise provisions.

38The foregoing description of the Amended Warrant contained in this Part II, Item 5 of our Quarterly Report on Form 10-Q does not purport to be complete and is qualified in its entirety by the full and complete terms of the Amended Warrant, a copy of which is attached hereto as Exhibit 4.1 and incorporated herein by reference.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
