1. Organization and Summary of Significant Accounting Policies

Organization

Amedica Corporation was incorporated in the state of Delaware on December 10, 1996. Amedica Corporation is a materials company focused on developing, manufacturing and selling silicon nitride ceramics that are used in medical implants and in a variety of industrial devices. At present, Amedica Corporation commercializes silicon nitride in the spine implant market and believes that its silicon nitride manufacturing expertise positions it favorably to introduce new and innovative products in the medical and non-medical fields. Amedica Corporation also believes that it is the first and only company to commercialize silicon nitride medical implants. Amedica Corporation acquired US Spine, Inc. (“US Spine”), a Delaware spinal products corporation with operations in Florida, on September 20, 2010. Amedica Corporation and US Spine are collectively referred to as “Amedica” or “the Company” in these condensed consolidated financial statements. The Company’s products are sold primarily in the United States.

Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) and include all assets and liabilities of the Company and its wholly-owned subsidiary, US Spine. All material intercompany transactions and balances have been eliminated in consolidation. SEC rules and regulations allow the omission of certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, so long as the statements are not misleading. In the opinion of management, these financial statements and accompanying notes contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position and results of operations for the periods presented herein. These condensed consolidated financial statements should be read in conjunction with the consolidated audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on March 29, 2018. The results of operations for the six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018. The Company’s significant accounting policies are set forth in Note 1 to the consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2017.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the periods then ended. Actual results could differ from those estimates. The most significant estimates relate to inventory, stock-based compensation, long-lived and intangible assets and the liability for preferred stock and common stock warrants.

Liquidity and Capital Resources

The condensed consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern within one year from the date of issuance of these condensed consolidated financial statements.

For the six months ended June 30, 2018 and 2017, the Company incurred net losses of $5.7 million and $2.2 million, respectively, and used cash in operations of $5.9 million and $3.4 million, respectively. The Company had an accumulated deficit of $226.3 million and $220.6 million as of June 30, 2018 and December 31, 2017, respectively. To date, the Company’s operations have been principally financed by proceeds received from the issuance of preferred and common stock, convertible debt and bank debt and, to a lesser extent, cash generated from product sales. It is anticipated that the Company will continue to generate operating losses and use cash in operating activities. The Company’s continuation as a going concern is dependent upon its ability to increase sales, implement cost saving measures, maintain compliance with debt covenants and/or raise additional funds through the capital markets. Whether and when the Company can attain profitability and positive cash flows from operating activities or obtain additional financing is uncertain.

In 2016, the Company implemented certain cost saving measures, including workforce and office space reductions, and will continue to evaluate additional cost savings alternatives during 2018. These additional cost savings measures may include additional workforce and research and development reductions, as well as cuts to certain other operating expenses. In addition to these cost-saving measures, the Company is taking measures to increase sales revenue. These efforts include actively generating additional scientific and clinical data to have it published in leading industry publications. The unique features of the Company’s silicon nitride material are not well known, and the Company believes that the publication of such data would help sales efforts as the Company approaches new prospects. The Company is also making additional changes to the sales strategy, including a focus on revenue growth of silicon nitride lateral lumbar implants, the recently developed pedicle screw system known as Taurus, a variation of the Taurus system known as Taurus MIS and a newly developed interbody device known as C+CSC with Lumen.

The Company has common stock that is publicly traded and has been able to successfully raise capital when needed since the date of the Company’s initial public offering. The Company has engaged in discussions with investment and banking firms to examine financing alternatives, including options to encourage the exercise of outstanding warrants and other lending alternatives. To this effect, in March 2018, the Company closed on gross proceeds of $1.4 million, before payment of placement agent fees and costs on a warrant reprice and exercise transaction. See discussion regarding Warrant Reprice March 2018 in Note 8 below. Additionally, on May 14, 2018, we closed on a public offering of units, consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million, which excludes underwriting discounts and commissions and offering expenses payable by the Company.

These uncertainties create substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Reverse Stock Split

On November 10, 2017, the Company effected a 1 for 12 reverse stock split of the Company’s common stock. The par value and the authorized shares of the common and convertible preferred stock were not adjusted as a result of the reverse stock split. All common stock share and per-share amounts for all periods presented in these condensed consolidated financial statements have been adjusted retroactively to reflect the reverse stock split.

Significant Accounting Policies

There have been no significant changes to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

New Accounting Pronouncements Not Yet Adopted

In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-04 Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The amendments in this guidance eliminate the requirement to calculate the implied fair value of goodwill used to measure goodwill impairment charge (Step 2). As a result, an impairment charge will equal the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendment should be applied on a prospective basis. The guidance is effective for goodwill impairment tests in fiscal years beginning after December 15, 2021. Early adoption is permitted for goodwill impairment tests performed after January 1, 2017. The impact of this guidance for the Company will depend on the outcomes of future goodwill impairment tests.

In August 2016, the FASB updated accounting guidance on the following eight specific cash flow classification issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) contingent consideration payments made after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions; and (8) separately identifiable cash flows and application of the predominance principle. Under existing U.S. GAAP, there is no specific guidance on the eight cash flow classification issues aforementioned. These updates are effective for the Company for its annual period beginning January 1, 2019, and interim periods therein, with early adoption permitted. The guidance in this standard is not expected to have a material impact on the financial statements of the Company.

In February 2016, the FASB updated the accounting guidance related to leases as part of a joint project with the International Accounting Standards Board (“IASB”) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and operating leases with lease terms of more than 12 months. Additionally, this update will require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. The standard is effective for the Company for its annual period beginning January 1, 2020, and interim periods therein, with early adoption permitted. The Company is currently evaluating the potential impact this new standard may have on its financial statements but believes the most significant change will relate to building leases.

In May 2014, in addition to several amendments issued during 2016, the FASB updated the accounting guidance related to revenue from contracts with customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle is that a company should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. The standard defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for the Company for its annual period beginning January 1, 2019, and interim periods therein, and shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is in the preliminary stages of evaluating the impact that the new standard will have on its financial statements.

The Company has reviewed all other recently issued, but not yet adopted, accounting standards, in order to determine their effects, if any, on its results of operations, financial position or cash flows. Based on that review, the Company believes that no other pronouncements will have a significant effect on its financial statements.

New Accounting Pronouncements Adopted During the Six Months Ended June 30, 2018

In March 2016, the FASB updated the accounting guidance related to stock compensation. This update simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as the well as classification in the statement of cash flows. The standard is effective for the Company for its annual period beginning January 1, 2018. The guidance in this standard did not have a material impact on the financial statements of the Company.

The Company early adopted ASU 2017-11 - Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. This update changed the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The adoption of this update did not change the accounting conclusions related to any instruments issued prior to the adoption of this update as of January 1, 2018.

2. Basic and Diluted Net Loss per Common Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method. Dilutive common stock equivalents are primarily comprised of warrants for the purchase of common stock, Series B Convertible Preferred stock and stock options. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding because their effect would have been anti-dilutive due to the Company reporting a net loss. The Company had potentially dilutive securities, shares of common stock, totaling approximately 21.2 million and 1.5 million as of June 30, 2018 and 2017, respectively.

3. Inventories, net

Inventories consisted of the following (in thousands):

Finished goods included consigned inventory totaling approximately $1.7 million and $0.5 million as of June 30, 2018 and December 31, 2017. As of June 30, 2018, inventories totaling $1.2 million and $1.2 million were classified as current and long-term, respectively. Inventories classified as current represent the carrying value of inventories as of June 30, 2018, that management estimates will be sold by June 30, 2019.

4. Intangible Assets

Intangible assets consisted of the following (in thousands):

Amortization expense is expected to approximate $260,000 for the remainder of 2018, $536,000 per year through 2021, $369,000 in 2022 and total $140,000 thereafter, until fully amortized.

5. Fair Value Measurements

Financial Instruments Measured and Recorded at Fair Value on a Recurring Basis

The Company has issued certain warrants to purchase shares of common stock, which are considered derivative liabilities because they have registration rights which could require a cash settlement and are re-measured to fair value at each reporting period in accordance with accounting guidance. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

The Company classifies assets and liabilities measured at fair value in their entirety based on the lowest level of input that is significant to their fair value measurement. No financial assets were measured on a recurring basis as of June 30, 2018 and December 31, 2017. The following tables set forth the financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy as of June 30, 2018 and December 31, 2017:

The Company did not have any transfers of assets and liabilities between Level 1 and Level 2 of the fair value measurement hierarchy during the six months ended June 30, 2018 and 2017.

Common Stock Warrants

The Company has issued certain warrants to purchase shares of common stock, which are considered derivative liabilities because they have registration rights which could require a cash settlement and are re-measured to fair value at each reporting period in accordance with accounting guidance. As of June 30, 2018 and December 31, 2017, $0.5 million and $0.5 million, respectively, of the derivative liability was calculated using the Black-Scholes-Merton valuation model. As of June 30, 2018 and December 31, 2017, $6.1 million and $0.9 million of the derivative liability was calculated using the Monte Carlo Simulation valuation model.

The assumptions used in estimating the common stock warrant liability using the Black-Scholes-Merton valuation model as of June 30, 2018 and December 31, 2017 were as follows:

The assumptions used in estimating the common stock warrant liability using the Monte Carlo Simulation valuation model as of June 30, 2018 and December 31, 2017 were as follows:

In addition, if at any time after the second anniversary of the issuance of the warrant, both: (1) the 30-day volume weighted average price of the Company’s stock exceeds $3.00; and (2) the average daily trading volume for such 30-day period exceeds $350,000, the Company may call this warrant for $0.01 per share. Because of the call provisions, management believes the Monte Carlo Simulation valuation model provides a better estimate of fair value for the warrants issued during July 2016 and January 2017 than the Black-Scholes-Merton valuation model.

6. Accrued Liabilities

Accrued liabilities consisted of the following (in thousands):

7. Debt

L2 Capital Debt

On January 31, 2018, the Company signed a promissory note in the aggregate principal amount of up to $0.84 million (the “L2 Note”) for an aggregate purchase price of up to $0.75 million and warrants to purchase up to an aggregate of 68,257 shares of common stock of the Company (the “Warrants”) at an exercise price of $3.31 per share. The maturity date is six months from date of funding. The L2 Note bears interest at a rate of 8% per year and a default interest rate of 18% per year. The L2 Note may be converted by the holder of the L2 Note at any time following an event of default. The conversion price of the L2 Note in the event of a default is equal to the product of (i) 0.70 multiplied by (ii) the lowest volume weighted average price, or VWAP, of the Company’s common stock during the 20-day trading period ending in the holder of the L2 note’s sole discretion on the last complete trading day prior to conversion, or, the conversion date.

On May 14, 2018, the Company closed on an underwritten public offering of units, consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million. Part of the proceeds from this offering were used to pay off the outstanding debt with L2 Capital. The total payoff amount totaled $1.1 million, with a net of $0.7 in principal and $0.4 in interest.

Hercules and MEF I, LP/Anson Investments Debt Exchange

On January 3, 2018, the Company entered into an Assignment Agreement (the “Assignment Agreement”) with MEF I, LP and Anson Investments Master Fund (collectively the “Assignees” and each an “Assignee”), Hercules Technology III, L.P. (“HT III”) and Hercules Capital, Inc. (“HC” and, together with HT III, “Hercules”), pursuant to which Hercules assigned to the Assignees all amounts remaining due under the Loan and Security Agreement, dated June 30, 2014, as amended, between the Company and Hercules (the “Loan and Security Agreement”) and (2) the note (the “Hercules Note”) between the Company and Hercules evidencing the amounts due under the Loan and Security Agreement. The total amount assigned by Hercules to the Assignees in the aggregate was $2,264,623 and is secured by the same collateral underlying the Loan and Security Agreement. Subsequently, the Company entered into an exchange agreement pursuant to which the Assignees agreed to exchange the Hercules Term Loan obligation acquired by them for two senior secured convertible promissory notes issued by the Company, each in the principal amount of $1.1 million for an aggregate principal amount of $2.2 million, (the “Exchange Notes”). The Exchange Notes will mature on February 3, 2019 (the “Maturity Date”). The Exchange Notes bear interest at a rate of 15% per annum. Prior to the Maturity Date, principal and interest accrued under the Exchange Notes is payable in cash or, if certain conditions are met, payable in shares of common stock of the Company. All principal accrued under the Exchange Notes are convertible into shares of the Company’s common stock (“Conversion Shares”) at the election of the holders at any time at a fixed conversion price of $3.87 per share. Upon the occurrence of an event of default, the Assignees are entitled to convert all or any part of their Exchange Notes at a conversion price (the “Alternate Conversion Price”) equal to 70% of the lowest traded price of the Company’s common stock during the ten trading days prior to the conversion date, provided that (i) in no event may the Alternate Conversion Price be less than $1.75 per share and (ii) the Assignees shall not be entitled to receive more than 19.99% of the outstanding common stock. So long as these Exchange Notes remain outstanding or the Assignees hold any Conversion Shares, the Company is prohibited from entering into any financing transaction pursuant to which the Company sells its securities at a price lower than $1.75 per share. The Exchange Notes are secured by a first priority security interest in substantially all assets, including intellectual property, of the Company and contains covenants restricting payments to certain Company affiliates.

On May 14, 2018, the Company closed on an underwritten public offering of units, consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million. Part of the proceeds from this offering were used to pay off the outstanding debt with MEF I, L.P. and Anson Investments. The total payoff was $1.6 million, with $1.4 million in principal and $0.2 million in interest.

North Stadium Term Loan – Related Party (Extension)

In July 2018, the Company entered into an extension to the term loan with North Stadium Investments, LLC. The extension moved the due date of the loan from July 28, 2018 to October 28, 2018, at which time all principal and unpaid interest are due and payable. The monthly interest only payments will continue through the payoff on October 28, 2018.

North Stadium Term Loan – Related Party

On July 28, 2017, the Company entered into a $2.5 million term loan (the “North Stadium Loan”) with North Stadium Investments, LLC (“North Stadium”), a company owned and controlled by the Company’s Chief Executive Officer and Chairman of the Board. The North Stadium Loan bears interest at 10% per annum and requires the Company to make monthly interest only payments from September 5, 2017 through July 5, 2018. All principal and unpaid interest (if any) under the Loan are due and payable on July 28, 2018. The North Stadium Loan is secured by substantially all of the Company’s assets but is junior to the security interest in assets encumbered by the Hercules Term Loan now held by MEF I and Anson Investments. In connection with the North Stadium Loan, the Company also issued North Stadium a warrant to purchase up to 55,000 shares of the Company’s common stock at a purchase price of $5.04 per share, subject to a 5-year term. The relative estimated value of the warrants on the date of grant approximated $0.2 million, was recorded as a debt discount and is being amortized as interest expense over the life of the term loan.

Hercules Term Loan

On June 30, 2014, the Company entered into a Loan and Security Agreement with Hercules which provided the Company with a $20.0 million term loan. The Hercules Term Loan matured on January 1, 2018. The Hercules Term Loan included a $0.2 million closing fee, which was paid to Hercules on the closing date of the loan. The closing fee was recorded as a debt discount and was amortized to interest expense over the life of the loan. The Hercules Term Loan also included a non-refundable final payment fee of $1.7 million. The final payment fee was accrued and recorded to interest expense over the life of the loan. On January 3, 2018, the Hercules Term Loan and all amounts owing thereunder were assigned to MEF I and Anson Investments. See discussion above for a more detailed description of that transaction.

See discussion below with respect to the assignment of $3.0 million of the principal balance of the Hercules Term Loan to Riverside Merchant Partners, LLC (“Riverside”) and the subsequent agreement between the Company and Riverside to exchange the $3.0 million of the Hercules Term Loan held by Riverside for subordinated convertible promissory notes in the aggregate principal amount of $3.0 million.

Hercules and Riverside Debt Exchange

On April 4, 2016, the Company entered into an Assignment and Second Amendment to Loan and Security Agreement (the “Assignment Agreement”) with Riverside and Hercules, pursuant to which Hercules sold $1.0 million of the principal amount outstanding under the Hercules Term Loan to Riverside. In addition, pursuant to the terms of the Assignment Agreement, Riverside acquired an option to purchase an additional $2.0 million of the principal amount outstanding under the Hercules Term Loan from Hercules. Riverside subsequently exercised its option in full and acquired the additional $2.0 million of the outstanding principal amount of the Hercules Term Loan.

Long-term debt consisted of the following (in thousands):

8. Equity

May-June 2018 Preferred Stock Conversion

During both May 2018 and June 2018, Series B Convertible Preferred shareholders of the Company converted 4,072 shares of Series B Convertible Preferred Stock into 3,086,570 shares of common stock.

May 2018 Warrant Exercise

During March 2018, the Company repriced 832,000 warrants dated July 8, 2016. During May 2018, an additional 145,834 of the repriced warrants were exercised resulting in gross proceeds of $0.3 million.

May 2018 Unit Offering

On May 14, 2018, the Company closed on an underwritten public offering of units (“the Units”), consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million, which excludes underwriting discounts and commissions and offering expenses payable by Amedica. The offering was priced at a public offering price of $1,000 per unit. Each unit consisted of one share of Series B Convertible Preferred Stock, with a stated value of $1,100, and warrants to purchase up to 758 shares of common stock (the “May 2018 Warrants”). The May 2018 Warrants are initially exercisable at an exercise price of $1.60 per share and expire 5 years from the date of issuance. The Series B Preferred Stock is convertible into shares of common stock by dividing the stated value of $1,100 by: (i) for the first 40 trading days following the closing of this offering, $1.4512 (the “Conversion Price”), (ii) after 40 trading days but prior to the 81st trading day, the lesser of  (a) the Conversion Price and (b) 87.5% of the lowest volume weighted average price for our Common Stock as reported at the close of trading on the market reporting trade prices for the Common Stock during the five trading days prior to the 41st trading day, and (iii) after 80 trading days, the lesser of  (a) the Conversion Price and (b) 87.5% of the lowest volume weighted average price for our Common Stock as reported at the close of trading on the market reporting trade prices for the Common Stock during the five trading days prior to the date of the notice of conversion. In the case of (ii)(b) and (iii)(b) above, the share price shall not be less than $0.48 (the “Floor Price”). Each of the Conversion Price and Floor Price is subject to adjustment in certain circumstances.

The Company raised $15.0 million associated with the issuance of the Units, with $6.8 million, net of issuance costs of $0.6 million, allocated to the preferred stock and $6.9 million, net of issuance costs of $0.7 million, allocated to the warrants. In association with the warrants that were recorded as a derivative liability, the Company immediately expensed approximately $0.7 million of issuance costs. The 15,000 preferred shares were initially convertible into 11,369,900 shares of common stock and had an effective conversion rate of $1.45 per share based on the proceeds that were allocated to them. The conversion price was adjusted to $0.6543, effective July 12, 2018.

Warrant Reprice March 2018

During the three months ended March 31, 2018, the Company entered into a warrant amendment agreement (the “Amendment Agreement”) with certain holders of previously issued Series E Common Stock Purchase Warrants (collectively, “Investors”). In connection with that certain Series E Common Stock Purchase Warrant between the Company and Investors dated July 8, 2016, the Company issued to Investors warrants to purchase up to 832,000 shares of common stock (the “Warrant Shares”) at an exercise price of $12.00 per share, (the “Investors Warrants”). Under the terms of the Amendment Agreement, in consideration of Investors exercising 668,335 of the Investors Warrants (the “Warrant Exercise”), the exercise price per share of the Investor Warrants was reduced to $2.125 per share. 668,335 of the Investors Warrants were exercised resulting in gross proceeds to the Company of $1.4 million before payment of placement agent fees and costs. In addition, and as further consideration, the Company issued to Investors new warrants to purchase up to the number of shares of common stock equal to 100% of the number of Warrant Shares issued pursuant to the Warrant Exercise at an exercise price per share equal to $2.00 per share.

January 2017 Offering

During 2017, the Company completed a secondary offering in which the Company sold 741,667 shares of common stock and warrants to purchase 363,750 shares of common stock. The Company received approximately $3.9 million in proceeds from the offering, with $3.1 million, net of issuance costs of $0.6 million, allocated to common stock and $0.8 million allocated to the warrants. In association with the warrants that were recorded as a derivative liability, the Company immediately expensed $0.1 million of issuance costs. The warrants became exercisable on the closing date, expire on the five-year anniversary of the closing date, and have an initial exercise price per share equal to $6.60 subject to adjustments for events of recapitalization, stock dividends, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting the Company’s common stock.

July 2016 Offering

In July 2016, the Company completed a secondary offering in which the Company sold 5,258,000 Class A Units, including 1,650,000 units sold pursuant to the exercise by the underwriters of their over-allotment option, priced at $1.00 per unit, and 7,392 Class B Units, priced at $1,000 per unit.

Overview

We are a materials company focused on developing, manufacturing and selling silicon nitride ceramics that are used in medical implants and in a variety of industrial devices. At present, we commercialize silicon nitride in the spine implant market. We believe that our silicon nitride manufacturing expertise positions us favorably to introduce new and innovative products in the medical and non- medical fields. We also believe that we are the first and only company to commercialize silicon nitride medical implants.

We have received 510(k) regulatory clearance in the United States, a CE mark in Europe, ANVISA approval in Brazil, and ARTG and Prostheses approvals in Australia for a number of our devices that are designed for spinal fusion surgery. To date, more than 33,000 of our silicon nitride devices have been implanted into patients, with a 10-year successful track record. In March 2018, we received clearance from the United States Food and Drug Administration, or FDA, to market a modified novel composite spinal fusion device that combines porous and solid silicon nitride and is comparable to our commercially-available Valeo®C cervical implants.

We believe that silicon nitride has a superb combination of properties that make it ideally suited for human implantation. Other biomaterials are based on bone grafts, metal alloys, and polymers; all of which have practical limitations. In contrast, silicon nitride has a legacy of success in the most demanding and extreme industrial environments. As a human implant material, silicon nitride offers bone ingrowth, resistance to bacterial infection, resistance to corrosion, superior strength and fracture resistance, and ease of diagnostic imaging, among other advantages.

We market and sell our Valeo brand of silicon nitride implants to surgeons and hospitals in the United States and to selected markets in Europe and South America through more than 50 independent sales distributors who are supported by an in-house sales and marketing team. These implants are designed for use in cervical (neck) and thoracolumbar (lower back) spine surgery. In 2016, we entered into a 10-year exclusive distribution agreement with Shandong Weigao Orthopaedic Device Company Limited (“Weigao”) to sell Amedica-branded silicon nitride spinal fusion devices within the People’s Republic of China (“China”). Weigao, a large orthopedic company, has expertise in acquiring Chinese Food and Drug Administration (“CFDA”) approval of medical devices, and will assist us in obtaining regulatory approval. Weigao has committed to minimum purchase requirements totaling 225,000 implants in the first six years following CFDA clearance. We are also working with other partners in Japan to obtain regulatory approval for silicon nitride in that country. China and Japan are relevant because historically, ceramic implants are more familiar to, and more readily accepted by surgeons outside the United States, i.e., in Asia and Europe.

In addition to silicon nitride, we also sell metal-based products in the United States that provide surgeons and hospitals with a complete package for spinal surgery. These metal products are designed to address spinal deformity and degenerative conditions. Although metal products have accounted for approximately 61% and 51% of our product revenues for the six months ended June 30, 2018 and 2017, respectively, we remain focused on developing and promoting silicon nitride, and driving its adoption through a scientifically-intense, data-driven strategy.

In addition to direct sales, we have targeted original equipment manufacturer (“OEM”) and private label partnerships in order to accelerate adoption of silicon nitride, both in the spinal space, and also in future markets such as hip and knee replacements, dental, extremities, trauma, and sports medicine. Existing biomaterials, based on plastics, metals, and bone grafts have well-recognized limitations that we believe are addressed by silicon nitride, and we are uniquely positioned to convert existing, successful implant designs made by other companies into silicon nitride. We believe OEM and private label partnerships will allow us to work with a variety of partners, accelerate the adoption of silicon nitride, and realize incremental revenue at improved operating margins, when compared to the cost-intensive direct sales model.

We believe that silicon nitride addresses many of the biomaterial-related limitations in fields such as hip and knee replacements, dental implants, sports medicine, extremities, and trauma surgery. We further believe that the inherent material properties of silicon nitride, and the ability to formulate the material in a variety of compositions, combined with precise control of the surface properties of the material, opens up a number of commercial opportunities across orthopedic surgery, neurological surgery, maxillofacial surgery, and other medical disciplines.

We operate a 30,000 square foot manufacturing facility at our corporate headquarters in Salt Lake City, Utah, and we believe we are the only vertically integrated silicon nitride medical device manufacturer in the world.

Components of our Results of Operations

We manage our business within one reportable segment, which is consistent with how our management reviews our business, makes investment and resource allocation decisions and assesses operating performance.

Product Revenue

We derive our product revenue primarily from the sale of spinal fusion and fixation devices and related products used in the treatment of spine disorders. Our product revenue is generated from sales to three types of customers: (1) surgeons and hospitals; (2) stocking distributors; and (3) private label customers. Most of our products are sold on a consignment basis through a network of independent sales distributors; however, we also sell our products to independent stocking distributors and private label customers. Product revenue is recognized when all four of the following criteria are met: (1) persuasive evidence that an arrangement exists; (2) delivery of the products has occurred; (3) the selling price of the product is fixed or determinable; and (4) collectability is reasonably assured. We generate the majority of our revenue from the sale of inventory that is consigned to independent sales distributors that sell our products to surgeons and hospitals. For these products, we recognize revenue at the time we are notified the product has been used or implanted and all other revenue recognition criteria have been met. For all other transactions, we recognize revenue when title and risk of loss transfer to the stocking distributor or private label customers, and all other revenue recognition criteria have been met. We generally recognize revenue from sales to stocking distributors and private label customers at the time the product is shipped to the distributor. Stocking distributors and private label customers, who sell the products to their customers, take title to the products and assume all risks of ownership at time of shipment. Our stocking distributors and private label customers are obligated to pay within specified terms regardless of when, if ever, they sell the products. Our policy is to classify shipping and handling costs billed to customers as an offset to total shipping expense in the statement of operations, primarily within sales and marketing. In general, our customers do not have any rights of return or exchange.

Cost of Revenue

The expenses that are included in cost of revenue include all direct product costs if we obtained the product from third-party manufacturers and our in-house manufacturing costs for the products we manufacture. We obtain our non-silicon nitride products, including our metal products, from third-party manufacturers, while we currently manufacture our silicon-nitride products in-house.

Specific provisions for excess or obsolete inventory are also included in cost of revenue. In addition, we pay royalties attributable to the sale of specific products to some of our surgeon advisors that assisted us in the design, regulatory clearance or commercialization of a particular product. These payments are recorded as cost of revenue.

Gross Profit

Our gross profit measures our product revenue relative to our cost of revenue. We expect our gross profit to decrease as we expand the penetration of our silicon nitride technology platform through OEM and private label partnerships.

Research and Development Expenses

Our research and development costs are expensed as incurred. Research and development costs consist of engineering, product development, clinical trials, test-part manufacturing, testing, developing and validating the manufacturing process, manufacturing, facility and regulatory-related costs. Research and development expenses also include employee compensation, employee and non-employee stock-based compensation, supplies and materials, consultant services, and travel and facilities expenses related to research activities. To the extent that certain research and development expenses are directly related to our manufactured products, such expenses and related overhead costs are allocated to inventory.

As we continue to develop new spinal fusion products, our product candidates for total joint replacements, such as our total hip replacement product candidate, and dental applications, we expect to increase our total research and development expenses.

Sales and Marketing Expenses

Sales and marketing expenses consist of salaries, benefits and other related costs, including stock-based compensation, for personnel employed in sales, marketing, medical education and training. In addition, our sales and marketing expenses include commissions and bonuses, generally based on a percentage of sales, to our sales managers and independent sales distributors. We provide our products in kits or banks that consist of a range of device sizes and separate instruments sets necessary to perform the surgical procedure. We generally consign our instruments to our distributors or our hospital customers that purchase the device used in spinal fusion surgery. Our sales and marketing expenses include depreciation of the surgical instruments.

We expect our commissions to increase in absolute terms over time but remain approximately the same or decrease as a percentage of product revenue.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation for certain members of our executive team and other personnel employed in finance, legal, compliance, administrative, information technology, customer service, executive and human resource departments. General and administrative expenses also include other expenses not part of the other cost categories mentioned above, including facility expenses and professional fees for accounting and legal services.

RESULTS OF OPERATIONS - Unaudited

The following is a tabular presentation of our unaudited condensed consolidated operating results for the three and six months ended June 30, 2018 and 2017 (in thousands):

Product Revenue - Unaudited

The following table sets forth our product revenue from sales of the indicated product category for the three and six months ended June 30, 2018 and 2017 (in thousands):

For the three months ended June 30, 2018, total product revenue was $2.0 million as compared to $3.2 million in the same period 2017, a decrease of $1.2 million, or 36%. This decrease was due to the loss of surgeons and the renegotiation of pricing with some of our hospital groups.

For the six months ended June 30, 2018, total product revenue was $4.3 million as compared to $5.8 million in the same period 2017, a decrease of $1.5 million, or 26%. This decrease was due to the loss of surgeons and the renegotiation of pricing with some of our hospital groups.

The following table sets forth, for the periods indicated, our unaudited product revenue by geographic area (in thousands):

For the three months ended June 30, 2018, domestic revenue decreased by $1.2 million, or 36%. This is attributable to the loss of surgeons and the renegotiation of hospital pricing. International revenue decreased $12,000, or 41% as compared to the same period in 2017. After our Australian distributor, new in 2018, made purchases during the first quarter of 2018, international sales have followed the same pattern as our domestic sales.

For the six months ended June 30, 2018, domestic revenue decreased by $1.5 million, or 27%. This is attributable to the loss of surgeons and the renegotiation of hospital pricing. International revenue increased $0.06 million, or 88% as compared to the same period in 2017. This is due to our Australian distributor, new in 2018, making purchases of instrumentation equipment and inventory.

Cost of Revenue and Gross Profit

For the three months ended June 30, 2018, our cost of revenue decreased $0.2 million, or 28%, as compared to the same period in 2017. The decrease was due primarily to a decline in sales. Gross profit decreased $0.9 million, also attributable to the decline in sales. Gross margin percentage decreased 3% to 74%, primarily due to negotiation of sales prices on select contracts.

For the six months ended June 30, 2018, our cost of revenue decreased $0.3 million, or 24%, as compared to the same period in 2017. The decrease was primarily due a decline in sales. Gross profit decreased $1.2 million and was attributable to the corresponding decrease in revenue and cost of revenue. Gross margin remained the same at 76%.

Research and Development Expenses

For the three months ended June 30, 2018, research and development expenses decreased $31,000, or 2%, as compared to the same period in 2017. This decrease was primarily attributable to a decrease in payroll related expenses of $78,000 offset by the increase in various manufacturing expenses of $47,000.

For the six months ended June 30, 2018, research and development expenses increased $0.2 million, or 8%, as compared to the same period in 2017. This increase was primarily attributable to an increase in clinical studies expense of $0.1 million, and consulting, travel, product testing and fees expenses of $0.1 million.

General and Administrative Expenses

For the three months ended June 30, 2018, general and administrative expenses increased $32,000, or 3%, as compared to the same period in 2017. This increase was primarily attributable to an increase in accounting and legal expenses of $78,000, related to capital raising activities, and tax expense, offset by a decrease in payroll related expenses of $46,000.

For the six months ended June 30, 2018, general and administrative expenses increased $0.4 million, or 18%, as compared to the same period in 2017. This increase was primarily attributable to an increase in accounting and legal expenses of $0.2 million, related to capital raising activities, and tax expense of $0.2 million related to the effectuating of the November 2017 1-12 stock split.

Sales and Marketing Expenses

For the three months ended June 30, 2018, sales and marketing expenses decreased $0.7 million, or 37%, as compared to the same period in 2017. This decrease was primarily attributable to a decrease in commissions of $0.5 million due to the decrease in sales, and a decrease in consulting, contracting, travel and marketing expense of $0.2 million.

For the six months ended June 30, 2018, sales and marketing expenses decreased $1.1 million, or 32%, as compared to the same period in 2017. This decrease was primarily attributable to a decrease in commissions of $0.8 million due to the decrease in sales, and a decrease in consulting, contracting, travel and marketing expense of $0.3 million.

Other Expense, Net

For the three months ended June 30, 2018, other expense increased $0.3 million, or 1429%, as compared to the same period in 2017. This increase was primarily due to an increase in offering costs of $0.7 million related to the May 2018 public offering, the increase in interest expense of $0.4 million related to the payoff of debt, offset by the change in the fair value of the derivative liabilities in the amount of $0.8 million.

For the six months ended June 30, 2018, other expense increased $2.8 million, or 217%, as compared to the same period in 2017. This increase was primarily due to an increase in the loss on the extinguishment of derivative liabilities in the amount of $1.2 million, the increase in offering costs of $0.6 million related to the issuance of warrant derivative liabilities, the increase in interest expense of $0.5 million due to the extinguishment of debt, the increase in the loss on extinguishment of debt of $0.3 million and the increase in the change in the fair value of the derivative liabilities in the amount of $0.2 million.

Liquidity and Capital Resources

The condensed consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern within one year from the date of issuance of these condensed consolidated financial statements.

For the six months ended June 30, 2018 and 2017, we incurred net losses of $5.7 million and $2.2 million, respectively, and used cash in operations of $5.9 million and $3.4 million, respectively. We had an accumulated deficit of $226.3 million and $220.6 million as of June 30, 2018 and December 31, 2017, respectively. To date, our operations have been principally financed by proceeds received from the issuance of preferred and common stock, convertible debt and bank debt and, to a lesser extent, cash generated from product sales. It is anticipated that we will continue to generate operating losses and use cash in operating activities. Our continuation as a going concern is dependent upon our ability to increase sales, implement cost saving measures, maintain compliance with debt covenants and/or raise additional funds through the capital markets. Whether and when we can attain profitability and positive cash flows from operating activities or obtain additional financing is uncertain.

In 2016, we implemented certain cost saving measures, including workforce and office space reductions, and will continue to evaluate additional cost savings alternatives during 2018. These additional cost savings measures may include additional workforce and research and development reductions, as well as cuts to certain other operating expenses. In addition to these cost saving measures, the Company is taking measures to increase sales revenue. These efforts include actively generating additional scientific and clinical data to have it published in leading industry publications. The unique features of our silicon nitride material are not well known, and publication of such data would help sales efforts as we approach new prospects. We are also making additional changes to the sales strategy, including a focus on revenue growth of silicon nitride lateral lumbar implants and the recently developed pedicle screw system known as Taurus, a variation of the Taurus system known as Taurus MIS and a newly developed interbody devise known as C+CSC with Lumen.

On May 14, 2018, we closed on a public offering of units, consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million, which excludes underwriting discounts and commissions and offering expenses payable by the Company.

These uncertainties create substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Cash Flows - Unaudited

The following table summarizes, for the periods indicated, cash flows from operating, investing and financing activities (in thousands) – unaudited:

Net Cash Used in Operating Activities

Net cash used in operating activities increased $2.5 million to $5.9 million during the six months ended June 30, 2018, as compared to $3.4 million for the same period in 2017. Offset by the increase in the net loss and related non-cash add backs to the net loss, the increase in cash used in operating activities during 2018 was primarily due to changes in the movement of working capital items during the six months ended June 30, 2018 as compared to the same period in 2017 as follows: a $0.8 million change in accounts payable and accrued expenses, a $0.3 million change in inventories offset by a $0.4 million change in trade accounts receivable.

Net Cash Used in Investing Activities

Net cash used in investing activities decreased $0.3 million to $0.2 million during the six months ended June 30, 2018, compared to $0.5 million for the same period in 2017. The decrease in cash used in investing activities during 2018 was due to a net decrease of $0.4 million in purchases of property and equipment offset by an increase of $0.1 million in purchase of intangible assets.

Net Cash Provided by Financing Activities

Net cash provided from financing activities was $14.4 million during the six months ended June 30, 2018, compared to $0.5 million during the same period in 2017. The $13.9 million increase in 2018 was primarily attributable to $6.9 million in proceeds received from the issuance of warrant derivative liabilities, the $6.8 million in proceeds from the issuance of preferred stock, the $1.6 million in proceeds from the issuance of common stock in connection with the exercise of warrants, the decrease of $1.0 million is payments on debts and the $0.7 million in proceeds from the issuance of debt, offset by the decrease of $3.1 million in proceeds from the issuance of common stock.

L2 Capital Debt

On January 31, 2018, the Company signed a promissory note in the aggregate principal amount of up to $840,000 (the “L2 Note”) for an aggregate purchase price of up to $750,000 and warrants to purchase up to an aggregate of 68,257 shares of common stock of the Company (the “Warrants”) at an exercise price of $3.31 per share. The maturity date is six months from date of funding. The Note bears interest at a rate of 8% per year and a default interest rate of 18% per year. The Note may be converted by the holder of the Note at any time following an event of default. The conversion price of the Note in the event of a default is equal to the product of (i) 0.70 multiplied by (ii) the lowest volume weighted average price, or VWAP, of the Company’s common stock during the 20-day trading period ending in the Holder’s sole discretion on the last complete trading day prior to conversion, or, the conversion date.

On May 14, 2018, the Company closed on an underwritten public offering of units, consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million. Part of the proceeds from this offering were used to pay off the outstanding debt with L2 Capital. The total payoff was $1.1 million, with $0.7 million in principal and $0.4 million in interest.

Hercules and MEF I, LP/Anson Investments Debt Exchange

On January 3, 2018, the Company entered into an Assignment Agreement (the “Assignment Agreement”) with MEF I, LP and Anson Investments Master Fund (collectively the “Assignees” and each an “Assignee”), Hercules Technology III, L.P. (“HT III”) and Hercules Capital, Inc. (“HC” and, together with HT III, “Hercules”), pursuant to which Hercules assigned to the Assignees all amounts remaining due under the Loan and Security Agreement, dated June 30, 2014, as amended, between the Company and Hercules (the “Loan and Security Agreement”) and (2) the note (the “Hercules Note”) between the Company and Hercules evidencing the amounts due under the Loan and Security Agreement. The total amount assigned by Hercules to the Assignees in the aggregate was $2.3 million and is secured by the same collateral underlying the Loan and Security Agreement. Subsequently, the Company entered into an exchange agreement pursuant to which the Assignees agreed to exchange the Hercules Term Loan obligation acquired by them for two senior secured convertible promissory notes issued by the Company, each in the principal amount of $1.1 million for an aggregate principal amount of $2.2 million, (the “Exchange Notes”). The Exchange Notes will mature on February 3, 2019 (the “Maturity Date”). The Exchange Notes bear interest at a rate of 15% per annum. Prior to the Maturity Date, principal and interest accrued under the Exchange Notes is payable in cash or, if certain conditions are met, payable in shares of common stock of the Company. All principal accrued under the Exchange Notes are convertible into shares of the Company’s common stock (“Conversion Shares”) at the election of the holders at any time at a fixed conversion price of $3.87 per share. Upon the occurrence of an event of default, the Assignees are entitled to convert all or any part of their Exchange Notes at a conversion price (the “Alternate Conversion Price”) equal to 70% of the lowest traded price of the Company’s common stock during the ten trading days prior to the conversion date, provided that (i) in no event may the Alternate Conversion Price be less than $1.75 per share and (ii) the Assignees shall not be entitled to receive more than 19.99% of the outstanding Common Stock. So long as these Exchange Notes remain outstanding or the Assignees hold any Conversion Shares, the Company is prohibited from entering into any financing transaction pursuant to which the Company sells its securities at a price lower than $1.75 per share. The Exchange Notes are secured by a first priority security interest in substantially all assets, including intellectual property, of the Company and contains covenants restricting payments to certain Company affiliates.

On May 14, 2018, the Company closed on an underwritten public offering of units, consisting of convertible preferred stock and warrants, for gross proceeds of $15.0 million. Part of the proceeds from this offering were used to pay off the outstanding debt with MEF I, L.P and Anson Investments. The total payoff was $1.6 million, with $1.4 million in principal and $0.2 million in interest.

North Stadium Term Loan – Related Party (Extension)

In July 2018, the Company entered into an extension to the term loan with North Stadium Investments, LLC. The extension moved the due date of the loan from July 28, 2018 to October 28, 2018, at which time all principal and unpaid interest are due and payable. The monthly interest only payments will continue through the payoff on October 28, 2018.

North Stadium Term Loan – Related Party

On July 28, 2017, we entered into a $2.5 million term loan (the “North Stadium Loan”) with North Stadium Investments, LLC (“North Stadium”), a company owned and controlled by our Chief Executive Officer and Chairman of the Board. The North Stadium Loan bears interest at 10% per annum and requires us to make monthly interest only payments from September 5, 2017 through July 5, 2018. All principal and unpaid interest (if any) under the Loan is due and payable on July 28, 2018. The North Stadium Loan is secured by substantially all of our assets but is junior to security interest in assets encumbered by the Hercules Term Loan. In connection with the North Stadium Loan, we also issued North Stadium a warrant to purchase up to 55,000 shares of our common stock at a purchase price of $5.04 per share, subject to a 5-year term. The relative estimated value of the warrants on the date of grant approximated $0.2 million, which was recorded as a debt discount and is being amortized as interest expense over the life of the term loan.

Hercules Term Loan

On June 30, 2014, the Company entered into a Loan and Security Agreement with Hercules which provided the Company with a $20.0 million term loan. The Hercules Term Loan matured on January 1, 2018. The Hercules Term Loan included a $0.2 million closing fee, which was paid to Hercules on the closing date of the loan. The closing fee was recorded as a debt discount and was amortized to interest expense over the life of the loan. The Hercules Term Loan also included a non-refundable final payment fee of $1.7 million. The final payment fee was accrued and recorded to interest expense over the life of the loan. On January 3, 2018, the Hercules Term Loan and all amounts owing thereunder was assigned to MEF I and Anson Investments. See discussion above for a more detailed description of that transaction.

See discussion below with respect to the assignment of $3.0 million of the principal balance of the Hercules Term Loan to Riverside Merchant Partners, LLC (“Riverside”) and the subsequent agreement between the Company and Riverside to exchange the $3.0 million of the Hercules Term Loan held by Riverside for subordinated convertible promissory notes in the aggregate principal amount of $3.0 million.

Hercules and Riverside Debt Exchange

On April 4, 2016, the Company entered into an Assignment and Second Amendment to Loan and Security Agreement (the “Assignment Agreement”) with Riverside and Hercules, pursuant to which Hercules sold $1.0 million of the principal amount outstanding under the Hercules Term Loan to Riverside. In addition, pursuant to the terms of the Assignment Agreement, Riverside acquired an option to purchase an additional $2.0 million of the principal amount outstanding under the Hercules Term Loan from Hercules. Riverside subsequently exercised its option in full and acquired the additional $2.0 million of the outstanding principal amount of the Hercules Term Loan.
