1. BUSINESS OVERVIEW

Business

Roka Bioscience, Inc. (“Roka” or “the Company”) is focused on the development and commercialization of molecular assay technologies for the detection of foodborne pathogens. The Company was established in September 2009 through the acquisition of industrial testing assets and technology from Gen-Probe Incorporated, which was subsequently acquired by Hologic, Inc. (herein referred to as “Gen-Probe”).

The Company has limited capital resources, has experienced negative cash flows from operations and has incurred net losses since inception. The Company expects to continue to experience negative cash flows from operations and incur net losses in the near term as it devotes substantially all of its efforts on commercialization of its products and completion of its obligations under the asset purchase agreement discussed in Note 18. The Company’s business is subject to significant risks and its ability to successfully develop, manufacture and commercialize proprietary products is dependent upon many factors which include, but are not limited to, risks and uncertainties associated with materials, manufacturing scale-up, retention of key personnel, customer acceptance and competition. In addition, the Company’s debt agreement contains certain clauses which allow the lender to require repayment of the debt based on subjective factors regarding the Company’s business and performance, if those factors are considered a material adverse change by the lender.

On September 21, 2016, the Company closed a private placement in which it sold 22,500 shares of Series A Preferred Stock and 3,214,299 warrants to purchase Common Stock ("the Offering"). The Company received $21.3 million of net proceeds from the Offering after deducting placement agent fee and offering expenses, see Note 15 for further details.

On July 22, 2014, the Company completed an initial public offering ("IPO") in which it received $53.2 million of net proceeds from the offering after deducting underwriting discounts, commissions and offering expenses.

Going Concern

These financial statements have been prepared assuming that the Company will continue as a going concern. Based upon its current and projected cash flow, the Company notes there is substantial doubt about its ability to continue as a going concern within one year after the date that these financial statements are issued. The Company has entered into an asset purchase agreement for the sale of substantially all of its assets which is discussed in further detail in Note 18. The asset sale is the initial step in a contemplated liquidation of the Company. Liquidity requirements through the end of 2017 include interest and principal payments on the Company's outstanding debt and a payment to Gen-Probe of $2.5 million due in August 2017. The planned asset sale does not eliminate the substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty or any planned liquidation.

Concentration of Suppliers

The Company relies on single source suppliers, including Gen-Probe, for certain components and materials used in its products, including its Atlas Detection Assays. Since the Company’s contracts with these suppliers, including Gen-Probe, do not commit the suppliers to carry inventory or to make available any minimum quantities, the Company may be unable to obtain adequate supplies in a timely manner or on commercially reasonable terms.  If the Company loses such suppliers, or its suppliers encounter financial hardships, the Company may not be able to identify or enter into agreements with alternative suppliers on a timely basis on acceptable terms, if at all. Transitioning to a new supplier could be time consuming, may be expensive, may result in an interruption in the Company’s operations and could affect the performance specifications of the Company’s products. If the Company should encounter delays or difficulties in securing the quality and quantity of materials required for its products, the Company’s ability to manufacture its products would be interrupted which could adversely affect sales.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Roka Bioscience, Inc. have been prepared by the Company in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting, which do not conform in all respects to the requirements of U.S. GAAP for annual financial statements. The information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 20, 2017 (the “2016 Form 10-K”). Accordingly, these condensed consolidated notes to the unaudited financial statements should be read in conjunction with the 2016 audited financial statements and notes thereto prepared in accordance with U.S. GAAP. The unaudited financial statements have been prepared using accounting policies that are consistent with the policies used in preparing the Company’s audited financial statements for the year ended December 31, 2016. The condensed consolidated Balance Sheet as of December 31, 2016 was derived from the Company’s audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. The unaudited financial statements reflect all normal and recurring adjustments necessary, if any, for a fair statement of the Company’s financial position and results of operations for the interim periods presented. The results of operations for the six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 or for any other future annual or interim period. There have been no changes in the significant accounting policies from those included in the 2016 Form 10-K. However, in order to further clarify the Company's policy with respect to impairment of long-lived assets, below please find a description of such policy.

Impairment of Long-Lived Assets

The Company’s long-lived assets are primarily comprised of intangible assets and property, plant and equipment. The Company evaluates its finite-lived intangible assets and property, plant and equipment, for impairment whenever events or changes in circumstances indicate the carrying value of an asset or group of assets is not recoverable. If these circumstances exist, recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to future undiscounted cash flows expected to be generated by the asset group. If the Company’s estimated undiscounted future cash flows are below the asset group’s carrying value, the Company may recognize an impairment charge measured by its fair value. See Note 7 for further details.

Reverse Stock Split

In June 2016, the Company's shareholders approved an amendment to the Company's certificate of incorporation and grant of discretionary authority to the Board of Directors to effect a reverse stock split. On October 11, 2016, the Company's Board of Directors effected a 10:1 reverse stock split of the Company's Common Stock. In addition, effective on the date of the reverse stock split, the conversion price of the Company's Preferred Stock sold in the Offering detailed in Note 1 was adjusted proportionately, and consequently each share of such Preferred Stock became convertible into approximately 143 shares of Common Stock. Unless otherwise noted, the Company’s historical share and per share information have been retroactively adjusted as if such stock split and corresponding change in conversion ratio occurred on the first day of the first period presented.

Prior Period Corrections

Previously, the Company included approximately $3.3 million in Other current assets and Accruedexpenses and other current liabilities related to the settlement amount for the class action lawsuit filed against the Company. The amount in Other current assets represented the expected reimbursement from the Company's insurance provider and the amount in Accrued expenses and other current liabilities was determined based upon the proposed settlement amount. During April 2017, the Company received additional information regarding the status of the litigation which indicated the Company's insurance provider disbursed the settlement amount and the settlement amount was finalized by the court as of December 31, 2016. As such, the Company has revised the December 31, 2016 balance sheet as indicated in the table below.

	As previously reported	Change		As revised
Other	3,658	(3,275	)	383

The Company believes these corrections are not material to any previously issued financial statements and further notes these adjustments have no impact on the 2016 Consolidated Statement of Operations and Comprehensive Loss, the Consolidated Statement of Convertible Preferred Stock Stockholders' Equity (Deficit), or the net amounts presented in the Consolidated Statement of Cash Flows for the year ended December 31, 2016.

New Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies and adopted by the Company as of the specified effective date.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. This standard clarifies the treatment of specific cash flow issues in order to reduce existing diversity in practice. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not believe this new guidance will have a material impact on its financial statements.

In February 2016, the FASB issued ASU 2016-02, creating Topic 842, Leases which supersedes the guidance in former ASC 840, Leases, to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. The Company is currently in the process of evaluating the impact this new guidance will have on its financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This standard outlines a single comprehensive revenue recognition model for all contracts with customers and supersedes current revenue recognition guidance. The revenue standard contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of control of goods or services to its customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The new standard also includes enhanced disclosure requirements. During 2016, the FASB issued several accounting updates (ASU No. 2016-08, 2016-10 and 2016-12) to clarify implementation guidance and correct unintended application of the guidance. ASU 2014-09 provides companies with two implementation methods, companies can choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). The Company plans to adopt the new standard on January 1, 2018, using the “modified retrospective” method. The Company continues to make progress in its assessment and implementation of

(unaudited)

the new standard, however, completion of this assessment is still ongoing, and as such, the Company has not yet determined if the new standard will have a material impact on its revenue recognition accounting policy or its Consolidated Financial Statements.

Adoption of New Accounting Principle

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. The standard requires entities to classify all deferred tax assets and liabilities as noncurrent. The standard became effective for interim and annual periods beginning after December 15, 2016. The Company adopted this new guidance beginning with the annual period beginning January 1, 2017. No adjustments were required to be made to the financial statements as a result of the Company's adoption of this new guidance.

3. CASH AND CASH EQUIVALENTS

The Company’s entire balance of Cash and cash equivalents as of June 30, 2017 was held in demand accounts with one financial institution, which subjects the Company to significant concentrations of credit risk.

4. MARKETABLE SECURITIES

As of June 30, 2017 and December 31, 2016, the fair value of held-to-maturity marketable securities by type of security was as follows (amounts in thousands):

	Amortized Cost		Gross Unrealized Holding Gains		Gross Unrealized Holding Losses			Aggregate Fair Value
June 30, 2017
Short-term marketable securities
Debt securities	$	8,977	$	16	$	(5	)	$	8,988
December 31, 2016
Short-term marketable securities
Debt securities	$	16,001	$	—	$	(10	)	$	15,991

Marketable securities held by the Company are recorded at amortized cost and consist of United States treasury bills, commercial paper, U.S. government-related debt, and corporate debt securities. All short-term marketable securities held by the Company mature within one year from the respective balance sheet date.

Under the Second License Amendment, the Company obtained a two-year option to reduce the royalty rate it pays to Gen-Probe in exchange for an option payment of $2.5 million. Upon completion of its IPO in July 2014, the Company exercised its option and issued to Gen-Probe 865,063 shares of common stock valued at $10.51 per share on the issuance date and made a cash payment of $8.0 million. Under the Second License Amendment, the Company is required to make additional cash payments of $5.0 million on January 1, 2018 and $5.0 million on January 1, 2020. These payment terms were modified under a third amendment (the "Third License Amendment") entered into on August 16, 2017, see note 18 for additional details.

The aggregate cash and stock payments made to Gen-Probe along with the present value of the two$5.0 million payments described above were recorded as a $26.6 million addition to the Company's intangible technology asset in Intangible assets on the Balance Sheet and will be amortized on a straight-line basis through the end of the estimated remaining life of the technology asset. See Note 9 for further details on the additional required future cash payments described above.

Pursuant to the terms of the Second License Amendment, the Company committed to additional future contingent payments, as described in Note 11 below. If made, such additional payments will further reduce the royalty rate the Company pays to Gen-Probe, and will be recorded as additions to the Company's intangible technology asset upon payment and amortized over the estimated remaining life of the technology asset.

The Company assesses its intangible and other long-lived assets for impairment whenever events or other changes in circumstances suggest that the carrying value of an asset group may not be recoverable based on its undiscounted future cash flows. If the Company’s estimated undiscounted future cash flows are below the asset group’s carrying value, the Company may recognize an impairment charge measured by its fair value.

During the second quarter of 2017, due to revenues and customer acquisitions falling below the Company's previous projections, the Company prepared revised projections for revenue and expenses. Compared to the Company's previous projections, the revised projections indicated reduced revenue from sales of the Company's products, expected to result in continued and increased cash flow losses for the Company. Additionally, a decision was made to pursue a sale of the Company or its assets.

Based on these facts and events described above, the Company determined a triggering event had occurred, requiring an assessment of whether the asset group was impaired as of June 30, 2017. In addition, the Company determined the assets did not qualify for held-for-sale as of June 30, 2017 and as such the impairment analysis was performed under the held-for-use guidance.

The Company completed its assessment of the asset group, which includes the intangible asset, for recoverability. The recoverability assessment was based upon probability-weighted cash flow estimates resulting from updated revenue and expense projections. Based on the cash flow projections associated with the asset group, the Company determined that the asset group was impaired as of June 30, 2017. The Company subsequently determined the fair value of the asset group, considering the present value of future cash flows from a potential liquidation scenario as well as estimates of fair value based on an asset sale scenario.

Based on the impairment assessment, the Company determined that the fair value of the asset group, including the intangible asset, was $11.5 million as of June 30, 2017, and the Company recognized an impairment of $8.5 million on the intangible asset and an impairment of $3.2 million on fixed assets included in the asset group during the three months ended June 30, 2017. Further, as of June 30, 2017, the Company reduced the estimated remaining life of the intangible asset and related fixed assets to three months, based upon the most likely scenario used in the impairment analysis.

The following table summarizes the Company's intangible asset as of the periods presented (amounts in thousands):

	June 30, 2017			December 31, 2016

9. DEFERRED PAYMENTS

Gen-Probe supply agreement

In May 2011, the Company entered into a supply agreement with Gen-Probe to purchase Atlas instruments. Pursuant to the terms of the agreement, the Company can defer up to one half of the purchase price for up to 54 months from the date of delivery. The deferred amounts do not bear interest, and the Company has recorded the imputed interest component as a reduction of the deferred payment and as a reduction of the asset cost. The supply agreement provides for variable repayment terms based on a percentage of net sales as defined in the agreement, and the Company has estimated its net sales in determining amounts due for the 54 month term. The following table summarizes the amounts deferred under this agreement (amounts in thousands):

	As of June 30,			As of December 31,
	2017			2016
Current
Deferred payments, gross	$	2,000		$	2,076
Imputed interest	(62		)	(154		)
Deferred payments, net	$	1,938		$	1,922
Long-term
Deferred payments, gross	$	—		$	1,136
Imputed interest	—			(8		)
Deferred payments, net	$	—		$	1,128

The Company estimated the interest rate implicit in the extended payment terms by considering the rate at which it could obtain financing of a similar nature from other sources at the date of each transaction, as well as prevailing rates for similar debt instruments of issuers with similar credit ratings. The estimated effective interest rate used ranges from 9.9% to 11.2%.

In the three and six months ended June 30, 2017, the Company recorded approximately $0.04 million and $0.1 million, respectively, and in the three and six months ended June 30, 2016, the Company recorded approximately $0.1 million and $0.2 million, respectively as non-cash interest expense related to the deferred payments pursuant to the supply agreement with Gen-Probe.

Gen-Probe license amendment

The Second License Amendment to the license agreement with Gen-Probe detailed in Note 7 includes a $5.0 million payment due on January 1, 2018 and a $5.0 million payment due on January 1, 2020. Under the terms of the Second License Amendment, no interest payments are required and no interest rate is stated. The Company determined that imputed interest should be calculated and recognized in accordance with ASC-835, and the payments are recorded in Deferred payments on the Balance Sheet at their present value based upon a 7.6% interest rate for the payment due on January 1, 2018 and a 9.0% interest rate for the payment due on January 1, 2020. The difference between the present value and the amount payable is accreted to Deferred payments over the respective term with a corresponding charge to Interest expense. Pursuant to the Third License Amendment, which was entered into with Gen-Probe on August 16, 2017, the two payments of $5.0 million were reduced to one single payment of $2.5 million due in 2017. See Note 18 for further details.

10. NOTES PAYABLE

In November 2013, the Company entered into a loan and security agreement (the 'Comerica Loan") with Comerica Bank (“Comerica”) in which it borrowed $5.0 million. The interest under the loan accrues at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 3.15%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%. As of June 30, 2017, the rate was 7.65%. Additionally, the Comerica Loan contains various covenants that limit the Company’s ability to engage in specified types of transactions, including limiting the Company’s ability to; sell, transfer, lease or dispose of certain assets; engage in certain mergers and consolidations; incur debt or encumber or permit liens on certain assets, make certain restricted payments, including paying dividends on, or repurchasing or making distributions with respect to, the Company’s Common Stock; and enter into certain transactions with affiliates. The Company has been in compliance with all requirements since originally entering into the Comerica Loan.

In May 2015, the Company amended the loan and security agreement with Comerica (the “First Amendment”). The Comerica Amendment increased the borrowing under the Comerica Loan to $10.0 million and extended the interest-only period until December 31, 2015. Beginning January 1, 2016, the Company began making monthly payments which consist of accrued interest and equal principal payments in accordance with a 30-month amortization schedule.

In April 2017, the Company entered into a second amendment with Comerica (the "Second Amendment"). The Second Amendment provides for an interest only period for three months after which the Company will begin making monthly payments which consist of accrued interest and equal principal payments in accordance with a 15-month amortization schedule. The interest rate under the Second Amendment accrues at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 3.40%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%. In connection with the Second Amendment, the Company issued an additional warrant to Comerica to purchase up to an aggregate of 8,403 shares of Common Stock at $3.57 per share and modified the exercise price of the warrants previously granted to Comerica under the Comerica Loan and the first amendment to $3.57 per share. The value of the new warrant and the incremental value due to the amendment of the previously issued warrants were recorded as a reduction to Notes payable with a corresponding offset to Additional paid-in capital. The value of the new warrant and the incremental value due to the modified pricing of the existing Comerica warrants were recorded as a reduction to Notes payable with a corresponding offset to Additional paid-in capital, see Note 15 for further details.

In connection with the Comerica Loan and the two amendments, the Company recorded the note net of expenses paid to Comerica, the value of the warrants issued to Comerica and the incremental value due to the amendment of the warrants at the time of the repricing. The difference between the liability recorded and the face value of the note will be accreted to Notes payable over the term of the loan with a corresponding charge to Interest expense.

Pursuant to the Second Amendment, the amount of unrestricted cash and/or marketable securities the Company is required to maintain with Comerica at all times was reduced from $5.0 million to $4.0 million. The Company has been in compliance with these requirements since implemented. In addition, the Second Amendment makes available to the Company a revolving line of credit of up to $4.0 million but not to exceed 80% of qualified receivables as defined in the Second Amendment. Borrowings under the revolving line of credit accrue interest at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 1.95%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%.

As of June 30, 2017, the entire remaining balance of $5.0 million has been classified as Notes payable, current on the Balance Sheet, although only $4.0 million is due within one year. The remaining $1.0 million has also been classified as Notes payable, current because the Comerica Loan agreement contains a material adverse change clause which allows Comerica to require repayment of the debt based on subjective factors regarding the Company’s business and performance.

11. COMMITMENTS AND CONTINGENCIES

Operating Leases

In April 2017, the Company amended the lease for its Warren, NJ laboratory and office space. The amendment provides for the termination of the lease of laboratory space and for extending the lease on office space through June 2023. The termination and extension resulted in additional future commitments of approximately $1.4 million. There have been no other significant changes to the Company’s operating leases as disclosed in the Company’s most recent audited financial statements.

Commitments

During the six months ended June 30, 2017, there have been no significant changes to the Company’s commitments as disclosed in the Company’s most recent audited financial statements except as it relates to the reduction in commitments under the Third License Amendment entered into with Gen-Probe on August 16, 2017 previously noted. See Note 18 for further details.

Contingent liabilities

In addition to the commitments disclosed in the Company’s most recent audited financial statements, the Second License Amendment to the license agreement with Gen-Probe detailed in Note 9 provided for additional milestone payments of up to $6.0 million which will further reduce the royalty rate paid. Such payments were removed under the terms of the Third License Amendment entered into on August 16, 2017. See Note 18 for further details.

Legal Matters

The Company may periodically become subject to legal proceedings and claims arising in connection with its business. Except as set forth below, the Company is not currently involved in any legal proceedings, nor are any claims pending against the Company.

A putative securities class action originally captioned Ding v. Roka Bioscience, Inc., Case No. 3:14-cv-8020, was filed against the Company and certain of its officers and directors in the United States District Court for the District of New Jersey on December 24, 2014, on behalf of a putative class of persons and entities who had purchased or otherwise acquired securities pursuant or traceable to the Registration Statement for the Company’s IPO. The original putative class period ran from July 17 through November 6, 2014.  The original complaint asserted claims under the Securities Act of 1933 and contended that the IPO Registration Statement was false and misleading, or omitted allegedly material information, in connection with the Company’s statements about its placement of Atlas instruments and its expectations of future growth and increased market share, and the Company’s alleged failure to disclose “known trends and uncertainties about the Company’s sales.”  The alleged misrepresentations and omissions purportedly came to light when the Company issued its third-quarter 2014 earnings release on November 6, 2014.

Pursuant to the Private Securities Litigation Reform Act of 1995, the court appointed Stanley Yedlowski as lead plaintiff and The Rosen Law Firm as lead counsel on April 21, 2015. The lead plaintiff then filed an amended complaint, captioned Stanley Yedlowski v. Roka Bioscience, Inc., Case No. 14-cv-8020, on June 23, 2015. The amended complaint pled Securities Act claims on behalf of persons and entities who had purchased or otherwise acquired Roka securities pursuant or traceable to the IPO Registration Statement during an extended putative class period, running from July 17, 2014 through March 26, 2015. The amended complaint alleged that the Registration Statement was false or misleading in that it failed to disclose that the Company’s customers purportedly were experiencing false positives and other usage issues with the Company’s Listeria assays apparently arising from the customers’ employees’ inability to follow the Company’s Listeria assay workflow. The amended complaint alleged that the full extent of the purported misstatements and omissions was not revealed until March 26, 2015. Defendants filed a motion on August 25, 2015 to dismiss the amended complaint, and plaintiffs filed an opposition to that motion on October 9, 2015. The parties entered into a settlement agreement, which was approved by the court in December 2016, to pay approximately $3.3 million. As of June 30, 2017, all payments have been made in accordance with the settlement agreement and the corresponding receivable and liability are no longer recorded on the Company's Balance Sheet.

The Company sells its products in various jurisdictions and is subject to federal, state and local taxes including, where applicable, sales and use tax. While the Company believes that it has properly paid or accrued for all such taxes based on its interpretation of applicable law, tax laws are complex and interpretations differ. Periodically, the Company may be audited by taxing authorities, and it is possible that additional assessments may be made in the future.

12. FAIR VALUE MEASUREMENTS

The Company’s financial instruments consist of cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable, short-term deferred payments, deferred payments, notes payable, accrued expenses and Convertible Preferred Stock Warrants. The carrying amounts of cash and cash equivalents, trade accounts receivable, accounts payable, short-term deferred payments and accrued expenses approximate their fair values because of the short-term nature of the instruments, or, in the case of the deferred payments and notes payable, because the interest rates the Company believes it could obtain for similar borrowings is similar to its existing interest rates.  The carrying amount of the Company's marketable securities is the amortized cost basis based upon their held-to-maturity classification.

In addition to the above noted financial instruments, as discussed in Note 7, the Company's intangible asset and certain fixed assets have been impaired during the three months ended June 30, 2017 and are recorded at approximate fair market value as of that date.

The following table summarizes the fair value information for the Company’s cash held in money market deposit accounts and its marketable securities at June 30, 2017 and December 31, 2016 (amounts in thousands):

A portion of the Company’s cash and cash equivalents are held in money market deposit accounts and a portion of the Company's short-term marketable securities are United States treasury bills, each of which are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices.

The Company's short-term marketable securities not classified within Level 1 of the fair value hierarchy are comprised of commercial paper, U.S. government-related debt, and corporate debt securities, all of which are classified as  Level 2 within the fair value hierarchy. The Company estimates the fair values of these marketable securities by taking into consideration valuations obtained from its investment manager, which utilizes industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. There have been no transfers between levels during the reporting period.

13. CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS’ EQUITY (DEFICIT)

Authorized stock

In connection with the seventh amended and restated certificate of incorporation effective on July 22, 2014, the total authorized shares of stock was changed to 520,000,000 of which 500,000,000 shares are designated as common stock with a par value of $0.001 per share and 20,000,000 shares are designated as "blank check" preferred stock with a par value of $0.001 per share.

Convertible Preferred Stock

On September 21, 2016, the Company closed a private placement offering (the "Offering") in which it issued and sold 22,500 shares of Series A Preferred Stock ("Preferred Stock") and five-year warrants (the "Investor Warrants") to purchase an aggregate of 3,214,299 shares of the Company’s Common Stock, par value $0.001 (the “Warrant Shares”) at a purchase price of $1,000 per share of Preferred Stock for aggregate gross proceeds of $22.5 million. The shares of Preferred Stock were convertible into common stock at a conversion rate of $7.00 per share of Common Stock and were immediately convertible at the option of the holder up to the holder's pro-rata share of 19.999% of the Company's Common Stock outstanding on the closing date of the Offering. All shares of Preferred Stock not previously converted were converted to Common Stock automatically upon shareholder approval which was obtained at a special shareholder meeting held on November 10, 2016.

Registration rights

Holders of approximately 0.8 million shares of the Company's outstanding Common Stock have rights, subject to certain conditions, to require that the Company file a registration statement under the Securities Act covering the registration of such shares of Common Stock, as well as piggyback registration rights. These rights are provided under the terms of an investor rights

agreement between the Company and the holders of the registrable securities, which will expire upon the earlier of (i) five years after the Company's IPO and (ii) as to a holder, at such time as all registrable securities held by such holder may be sold without restriction under Rule 144.

In connection with the Offering, on September 21, 2016, the Company entered into a registration rights agreement which provides that the Company would prepare and file with the U.S. Securities and Exchange Commission (the “SEC”), a resale shelf registration statement covering the Conversion Shares and Warrant Shares. Accordingly, on October 7, 2016, the Company filed an S-3 registration statement which was declared effective on October 24, 2016 enabling registration of the Conversion Shares and the Warrant Shares. The Company is required to maintain the effectiveness of such registration statement until the earlier of: (i) the date that all registrable securities covered by such registration statement have been sold, thereunder or pursuant to Rule 144 or (ii) the date that all registrable securities covered by such registration statement may be sold without limitation pursuant to Rule 144 (the “Effectiveness Period”). Subject to certain exceptions set forth in the registration rights agreement, if the Company fails to maintain the effectiveness of the registration statement during the Effectiveness Period, the Company will be required to pay to each holder an amount in cash equal to the product of 1.5% multiplied by the aggregate purchase price paid by such holder pursuant to the securities purchase agreement, subject to a cap equal to 10.0% of the aggregate purchase paid by such holder pursuant to the securities purchase agreement.

14. STOCK-BASED COMPENSATION

Effective upon the closing of the IPO, the Company adopted the Roka Bioscience, Inc. 2014 Equity Incentive Plan (the "2014 Plan"). The 2014 Plan initially made available 108,695 shares to be granted to employees, officers, directors, consultants, advisors or other individual service providers of the Company. On February 28, 2017, the Company held a special shareholder meeting at which the shareholders voted to increase the total number of shares available under the 2014 Plan to 665,340. Additionally, the amended plan provides for automatic increases on January 1st of each year for a period of ten years commencing on January 1, 2018 and ending on (and including) January 1, 2027, in an amount equal to 3% of the total number of shares of Common Stock outstanding on December 31st of the preceding calendar year.

Under the Roka Bioscience, Inc. 2009 Equity Incentive Plan (the “2009 Plan”), as amended on June 13, 2013, incentive and non-qualified stock options and restricted stock may be granted for up to a maximum of 202,885 shares to employees, consultants and directors of the Company. Effective upon adoption of the 2014 Plan, the Company has not and does not intend to issue additional shares under the 2009 Plan.

Stock options and shares of restricted stock granted under the 2009 Plan and the 2014 Plan have a maximum contractual term of ten years from the date of grant and generally vest over four years. For stock options, the exercise price may not be less than the fair value of the stock on the grant date.

The Company recognized stock compensation expense as follows (amounts in thousands):

	For the Three Months Ended   June 30,				For the Six Months Ended June 30,
	2017		2016		2017		2016
Stock options	$	125	$	170	$	229	$	380
Restricted stock	$	231	$	185	$	395	$	370

The Company granted approximately 411,000 stock options and 5,000 shares of restricted stock during the six months ended June 30, 2017, valued at approximately $1.0 million and $0.02 million, respectively. The Company granted approximately 100,000 stock options and 2,500 shares of restricted stock, valued at $0.6 million and $0.01 million, respectively, during the six months ended June 30, 2016.

The Company determines the fair value of stock option awards at the date of grant using a Black-Scholes valuation model. This model requires the Company to make assumptions and judgments on the expected volatility, dividend yield, the risk-free interest rate and the expected term of the stock options. The following ranges of assumptions were utilized for stock options granted during the periods indicated:

17

ROKA BIOSCIENCE, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

	For the Six Months Ended June 30,
	2017	2016
Expected life in years	5.5-6.2	5.5-6.2
Interest rate	1.86%-2.11%	1.27%-1.92%
Volatility	85% - 89%	80% - 88%
Dividend yield	—	—

The Company estimates the expected life of its employee stock options using the “simplified” method, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the option due to its lack of sufficient historical data. The risk-free interest rates are based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The expected stock price volatility rates are based on average historical volatilities of the common stock of the Company and a group of public companies in similar industries. The Company has no history or expectations of paying dividends on its Common Stock and therefore uses a zero percent dividend yield in the Black-Scholes option pricing model.

15. WARRANTS

As of June 30, 2017, there were 3,469,233 warrant shares outstanding with a weighted average exercise price of $7.12 per share.

Warrants Issued prior to IPO

In connection with the closing of the loan and security agreement in November 2013 discussed in Note 10, and an additional loan and security agreement (the 'TriplePoint Loan") which was paid off in 2015, the Company issued warrants to purchase up to an aggregate of 352,941 shares of Series E preferred stock with an exercise price of $1.28. Upon issuance, the Company recorded liabilities of approximately $0.08 million for the warrants issued. The initial fair value of the warrant issued to Comerica of approximately $0.03 million was deemed a discount on the debt issued by Comerica and is being accreted to interest expense over the term of the Comerica Loan. The initial fair value of the remaining warrants issued were capitalized in Other assets on the Balance Sheet as part of debt issuance costs and were amortized to Interest expense. In connection with borrowings made under the TriplePoint Loan in March 2014, one of the warrants issued to TriplePoint became exercisable for an additional 156,863 shares of Series E. The related fair value of approximately $0.1 million was deemed a discount on the debt issued at that time and was accreted to interest expense through the payoff of the loan in May 2015. In connection with the IPO, the Series E warrants converted into warrants to purchase common stock at their conversion rate of approximately 0.0906 common warrant shares to one Series E warrant share. As a result, and subsequent to the reverse stock split conducted in October 2016, became exercisable for 4,618 shares of Common Stock with an exercise price of $140.80.

Warrants Issued Subsequent to IPO

In connection with the First Amendment to the Comerica Loan on May 29, 2015, and the Second Amendment to the Comerica Loan on April 6, 2017, the Company issued additional warrants to Comerica to purchase up to an aggregate of 5,227 shares and 8,403 shares, respectively. The warrants issued in connection with the Second Amendment, have an exercise price of $3.57 per share and the warrants issued to Comerica under the original loan and the first amendment were modified in conjunction with the second amendment to have an exercise price of $3.57 per share.

In connection with the Offering discussed in Note 13, the Company issued Investor Warrants to purchase up to an aggregate of approximately 3,214,299 shares of the Company’s Common Stock and warrants to the placement agent to purchase up to an aggregate of approximately 236,686 shares of the Company's Common Stock (the "Placement Warrants"). The Investor Warrants and Placement Warrants have an exercise price of $7.00 and expire five years from the date of issuance.

16. NET LOSS PER SHARE

Basic net loss per share is calculated by dividing net loss applicable to common stockholders by the weighted-average shares outstanding during the period, without consideration for common stock equivalents. The weighted-average common shares outstanding excludes unvested restricted stock which although such shares are legally issued and outstanding, are not required to

share in losses of the Company and are therefore excluded from the net loss per share calculation. Diluted net loss per share is calculated by adjusting the weighted-average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. For purposes of the diluted net loss per share calculation, stock options and warrants are considered to be common stock equivalents but are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.

	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2017			2016			2017			2016
Net loss applicable to common shareholders (thousands)	$	(17,754	)	$	(7,560	)	$	(25,358	)	$	(15,736	)
Basic and diluted weighted average common shares outstanding	4,987,673			1,753,729			4,986,603			1,753,185
Basic and diluted loss per share	$	(3.56	)	$	(4.31	)	$	(5.09	)	$	(8.98	)

As the Company incurred a loss for the three and six months endedJune 30, 2017 and 2016, all unvested restricted stock awards were excluded from the calculation of basic net loss per share and all potential Common Stock shares issuable for stock options and warrants were excluded from the calculation of diluted net loss per share, as the effect of including them would have been anti-dilutive. Had the Company not incurred a loss, the dilutive effect of the unvested restricted stock awards on basic weighted average common shares outstanding and the dilutive effect of potential Common Stock shares issuable for stock options and warrants on the weighted-average number of Common Stock shares outstanding would have been as follows:

ROKA BIOSCIENCE, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

On August 16, 2017, the Company entered into a definitive agreement (the “Asset Purchase Agreement”) with Rokabio, Inc. (the “Buyer”), a newly formed subsidiary of Institute for Environmental Health (“IEH” or the “Buyer”), providing for the sale of substantially all of the assets of the Company in an all-cash transaction for an aggregate purchase price of $17.5 million, subject to certain adjustments set forth in the Asset Purchase Agreement (the “Asset Sale”).

On August 16, 2017, the Company entered into the Third License Amendment with Gen-Probe. The Third License Amendment provides that, among other things, the Company’s obligation to make milestone payments of $5.0 million on January 1, 2018 and $5.0 million on January 1, 2020 shall be reduced to a single $2.5 million milestone payment payable in August 2017. In the event the Company fails to make such $2.5 million milestone payment to Hologic, the Buyer may be entitled to make the payment upon closing of the Asset Sale, in which case the purchase price payable to the Company at closing would be reduced by $2.5 million to $15.0 million.

Pursuant to the terms of the Asset Purchase Agreement, the Company is required to provide transition services to the Buyer for a period of time following the closing of the Asset Sale through the earlier of (i) December 31, 2017 and (ii) the date as of which the Company has provided Buyer with an aggregate of 900,000 assay tests (the “Transition Period”). IEH has guaranteed all obligations of Buyer under the Asset Purchase Agreement, including the obligation to pay the purchase price.

The closing of the Asset Sale is subject to certain customary conditions, including the receipt of consent of the Company’s lender and approval by the Company’s stockholders of the transactions contemplated by the Asset Purchase Agreement. As part of the transaction, the Company will be required to make a $2.5 million milestone payment pursuant to its license agreement with Hologic, Inc.

The Company may terminate the Asset Purchase Agreement under certain circumstances, including if its Board of Directors determines in good faith that it has received a Superior Proposal (as defined in the Asset Purchase Agreement) and that it is required to terminate the Asset Purchase Agreement in order to comply with its fiduciary duties, and otherwise complies with certain terms of the Asset Purchase Agreement.  In connection with such termination or a termination after the Company’s stockholders have approved the Asset Purchase Agreement, the Company must pay a termination fee of $770,000 to the Buyer.  In addition, the Asset Purchase Agreement contains certain other termination rights for the Company.

Assuming stockholder approval of the Asset Sale and the plan of liquidation, liquidating distributions, in an amount to be determined, are expected to begin shortly after the completion of the Transition Period. The Company is analyzing the amount of liquidating distributions expected to be available for distribution to stockholders after payment of the Company’s liabilities, including the $2.5 million payment under the license agreement, repayment of the Company’s outstanding bank debt, the payment of expenses to be incurred for the operation of the business through the Transition Period, and the payment of expenses incurred in connection with the Asset Sale and winding down of the Company’s operations, and other liabilities incurred by the Company through such expected dissolution.

The Company cannot assure you that the conditions to the closing of the transactions contemplated by the Asset Purchase Agreement will be satisfied, or that the transactions will be completed. In the event the Company does not successfully complete the transactions contemplated by the Asset Purchase Agreement or complete a transaction resulting from a Superior Proposal, the Company will have limited options for financing its ongoing operations and will likely cease its operations or file for bankruptcy protection.

Overview

Background

We are a molecular diagnostics company focused on providing advanced testing solutions for the detection of foodborne pathogens. The proprietary molecular technology used in our assays enables us to offer accurate and rapid testing solutions while our fully automated Atlas instrument helps our customers reduce labor costs and minimize operator error. In late 2012, we launched our proprietary Atlas Detection Assays and Atlas instrument in the North American food safety testing market and we have worldwide rights to develop and commercialize our advanced molecular testing solutions for a wide range of other industrial applications.

Our company was founded in 2009 through the acquisition of the industrial application market assets of Gen-Probe. The acquisition included a worldwide license for Gen-Probe’s molecular assay technologies in the industrial application markets, access to certain instrument platforms as well as certain key development personnel. Our advanced molecular assays and automated instruments are derived from Gen-Probe technologies, which Gen-Probe uses in the highly regulated clinical diagnostics and blood screening markets.

We are focused on the commercialization of a comprehensive menu of molecular diagnostic products for the detection of foodborne pathogens under the Atlas brand name. We believe that other available pathogen test methods have significant performance gaps with respect to accuracy, time to results and automation, which are areas of critical importance to food processors, third-party contract testing laboratories and the government agencies that regulate food safety. Our Atlas solution is designed to provide our customers with accurate and rapid test results with reduced labor costs and improved laboratory efficiencies. In addition, we are developing a molecular chemistry and instrument platform, which is expected to address the needs of lower-volume throughput food safety customers, and to have potential clinical applications.

Our commercial success is dependent upon our ability to successfully market our Atlas Detection Assays and Atlas instrument. Our sales cycle is lengthy, often lasting longer than 12 months, which makes it difficult for us to accurately forecast revenue and other operating results. Through June 30, 2017, we have installed 59 Atlas instruments pursuant to commercial agreements, and for the six months ended June 30, 2017, we generated approximately $4.2 million in revenue, which was derived from a small number of customers. Since our inception in 2009, we have devoted substantially all of our resources to the development and commercialization of our advanced molecular testing solutions. We have incurred significant losses since our inception, and as of June 30, 2017, our accumulated deficit was $233.5 million.

On August 16, 2017, we entered into a definitive agreement, providing for the sale of substantially all of the assets of the Company in an all-cash transaction. Subject to approval by our shareholders, and completion of certain obligations to provide services to the buyer of our assets in a transition period, which is expected to end no later than December 31, 2017, we expect to liquidate the Company with liquidating distributions, in an amount to be determined, to begin shortly after the completion of the transition period.

Financial Operations Overview

Revenue

Our revenue is derived primarily from the sale of our Atlas Detection Assays and consumable supplies for our Atlas instruments. Our Atlas Detection Assays and our consumable supplies are designed to be used only on our Atlas instruments and our Atlas instruments will only accept our Atlas Detection Assays and our consumable supplies. This closed system model enables us to generate recurring revenue from the sale of our Atlas Detection Assays and other consumable supplies for use with each Atlas instrument we place. We mostly place our Atlas instruments with customers through reagent rental agreements, and recover the cost of providing the Atlas instruments, including services related to instrument maintenance, repairs, installation and training to our customers, in the amount charged for our Atlas Detection Assays. The reagent rental agreements are typically for a one-year initial period with automatic renewal provisions and have no minimum purchase obligations.

Shipping and handling costs incurred by us are included in our billings to customers. Revenue is generally recognized when our Atlas Detection Assays and other consumable supplies are shipped to the customer.

In addition to sales of our Atlas Detection Assays, we generate limited revenue from instrument rental and service and maintenance contracts. Revenue from instrument rental and service and maintenance contracts is recognized ratably over the term

22

of the contract. We also offer our Atlas instruments for sale, however during the six months ended June 30, 2017, we did not sell any Atlas instruments.

Potential customers for our products typically need to commit significant time and resources to evaluate our products, due to the nature and cost of our products and their impact on the potential customers’ businesses. To date, it has been difficult for us to accurately project revenues and other operating results due to these and other factors. In addition, the revenue generated from sales of our Atlas Detection Assays may fluctuate from time to time due to changes in the testing volumes of our customers. Upon closing of the agreement to sell our assets, but no later than December 31, 2017, we will no longer generate any revenues.

During the six months ended June 30, 2017, we placed nine instruments with customers, but also took back three instruments which were previously placed with customers. The three instruments we took back were not being utilized and therefore we do not expect their return will have a negative impact on our future revenue.

Operating Expenses

Cost of revenue

Cost of revenue primarily consists of the cost of materials, direct labor and manufacturing overhead costs associated with the production and distribution of our Atlas Detection Assays and consumable supplies for our Atlas instruments. Cost of revenue also includes depreciation on Atlas instruments installed with our customers under reagent rental or rental agreements, expenses related to service and maintenance of instruments, and royalties payable under our technology license agreement with Gen-Probe.

We manufacture our Atlas Detection Assays and consumable supplies in our San Diego facility, which has significant capacity for expansion. To date, the underutilized capacity in this facility has contributed to a high cost of revenue relative to revenue.

Research and development

Our research and development expenses are primarily associated with costs incurred for development, improvements and support activities for our Atlas instruments and Atlas Detection Assays. These expenses consist principally of payroll, employee benefits, as well as fees for contract research, consulting services and laboratory supplies. We expense all research and development costs as incurred.

Due to the completion of development of most assays for the Atlas instrument, we made reductions in our research and development department in the first quarter of 2017, and as a result, we expect our research and development expenses to decrease from their current level.

Selling, general and administrative

Our selling, general and administrative expenses include costs associated with our sales organization as well as our executive, accounting, information technology and human resources functions. These expenses consist principally of payroll, employee benefits, travel, and stock-based compensation, as well as professional services fees such as consulting, audit, tax and legal fees, and general corporate costs. We expense all general and administrative costs as incurred.

We expect our selling, general and administrative expenses to decrease from their current level, primarily as a result of efficiencies achieved through reductions made to our organization in the first quarter of 2017 and efficiencies gained in the execution of our commercial strategy.

Amortization of Intangible Assets

In connection with the acquisition of the industrial application market assets of Gen-Probe, we acquired certain in-process research and development projects that were recorded as an intangible asset with an indefinite life. Upon completion of the development of our first Atlas Detection Assay in January 2012, this asset was transferred from in-process research and development to a definite life intangible asset and we initiated amortization of the asset over its estimated useful life of 10 years. In June 2014, we entered into a second amendment to our license agreement with Gen-Probe, the "Second License Amendment". Under the Second License Amendment, we obtained a two-year option to reduce the royalty rate we pay to Gen-Probe in exchange for an option payment of $2.5 million. Upon completion of our IPO we exercised our option and issued to Gen-Probe 865,063 shares of common stock and made a cash payment of $8.0 million. Under the Second License Amendment we were required to make additional cash payments of $5.0 million on January 1, 2018 and $5.0 million on January 1, 2020. The aggregate cash and stock payments made to Gen-Probe along with the present value of the two $5.0 million payments described above were recorded as a $26.6 million addition to our intangible technology asset in Intangible assets on the Balance Sheet and will be amortized throughthe end of the estimated remaining life of the technology asset. In addition to the payments outlined above, the Second License Amendment provides for additional milestone payments of up to $6.0 million to further reduce the royalty rate paid. In August

23

2017, we entered into a third amendment to our license agreement with Gen-Probe, the "Third License Amendment". Under the Third License Amendment, the two $5.0 million payments along with the additional milestone payments of up to $6.0 million were reduced to a single payment of $2.5 million to be made in the third quarter of 2017.

We assess our intangible and other long-lived assets for impairment whenever events or other changes in circumstances suggest that the carrying value of an asset group may not be recoverable based on its undiscounted future cash flows. During the second quarter of 2017, due to revenues and customer acquisitions falling below our previous projections, we prepared revised projections for revenue and expenses. Compared to our previous projections, the revised projections indicated reduced revenue from sales of our products, which indicated continued cash flow losses. Additionally, a decision was made to pursue a sale of the Company or its assets. Based on these facts and events described above, we determined a triggering event had occurred, requiring an assessment of whether the asset group was impaired as of June 30, 2017.

We completed our assessment of the asset group, which includes the intangible asset, for recoverability. The recoverability assessment was based upon probability-weighted cash flow estimates resulting from updated revenue and expense projections. Based on the cash flow projections associated with the asset group, we determined that the asset group was impaired as of June 30, 2017. Based on the impairment assessment, we recognized an $11.6 million impairment charge to the asset group during the three months ended June 30, 2017, of which $8.5 million was allocated to the intangible asset. If we are unable to close a sale of the Company or its assets, we may recognize a further non-cash impairment charge with respect to the asset group including our intangible asset and other long-lived assets in future periods.

Other Income (Expenses)

Interest Income (Expense), net

Interest income is derived from cash and cash equivalents held with our banking institution as well as our short-term marketable securities. Interest income fluctuates based on the current interest rate available from our banking institution and the amount of funds held in cash accounts and marketable securities. Interest expense for the periods presented is associated with the debt outstanding under the loan and security agreement we entered into in November 2013 with Comerica Bank and its subsequent amendments, the two individual $5.0 million payments due to Gen-Probe on January 1, 2018 and January 1, 2020, respectively, under the terms of the royalty reduction option exercised under the terms of the amendment to our license agreement, as well as the extended payment terms provided to us by Gen-Probe on the purchase of Atlas instruments. See “—Liquidity and Capital Resources” below for further details.

Our interest expense has decreased as the balances due on our Comerica loan and under the extended payment terms provided to us by Gen-Probe on the purchase of Atlas instruments have been paid down. However, our interest expense may increase if the variable interest rate under the Comerica loan increases.

Revenue

Revenue increased by $0.3 million for the three months ended June 30, 2017, compared to the three months ended June 30, 2016. During the three months ended June 30, 2017, we sold 248,000 Atlas Detection Assays compared to 215,000 during the three months ended June 30, 2016.

As of June 30, 2017, we had 59 instruments placed with customers under commercial agreements, compared to 46 instruments as of June 30, 2016. For the three months ended June 30, 2017, the average revenue per instrument placed under commercial agreements was approximately $38,000, compared to $41,000 for the three months ended June 30, 2016. This decrease was due to the timing of additional instrument placements towards the end of the second quarter in 2017. During the three months ended June 30, 2017, three customers each accounted for more than 10% of revenues and generated approximately $1.1 million of revenue compared to three customers who generated $1.1 million of revenue in the three months ended June 30, 2016.

Operating Expenses

Cost of Revenue

Cost of revenue increased by $0.2 million for the three months ended June 30, 2017, compared to the three months ended June 30, 2016. The increase was primarily due to higher sales volumes of Atlas Detection Assays. Cost of revenue, as a percentage of revenue, decreased in the three months ended June 30, 2017 compared to 2016 due to better utilization of our manufacturing capacity.

Research and Development

Research and development expense decreased by $0.2 million to $1.3 million for the three months ended June 30, 2017, from $1.5 million for the three months ended June 30, 2016. The decrease was primarily due to a decrease of $0.1 million in payroll related expenses driven by a headcount reduction effectuated in the first quarter of 2017.

Selling, General and Administrative

Selling, general and administrative expense decreased by $1.1 million, to $3.4 million for the three months ended June 30, 2017, from $4.5 million for the three months ended June 30, 2016. The decrease was primarily due to a decrease in payroll and travel related expenses of approximately $0.9 million, primarily driven by a headcount reduction effectuated in the first quarter of 2017 and a decrease in depreciation by approximately $0.1 million.

Amortization of intangible assets

25

Amortization of intangibles was unchanged for the three months ended June 30, 2017 compared to the three months ended June 30, 2016.

Impairment of long-lived assets

During the three months ended June 30, 2017 we recognized an impairment of $11.6 million on certain long-lived assets including our intangible asset. No impairments were recorded during the three months ended June 30, 2016.

Other (Expense) Income

Revenue

Revenue increased by $0.7 million, to $4.2 million for the six months ended June 30, 2017, from $3.5 million, for the six months ended June 30, 2016, primarily as a result of increased demand for our Atlas Detection Assays and the sale of one Atlas instrument. During the six months ended June 30, 2017, we sold 496,000 Atlas Detection Assays compared to 412,000 in the six months ended June 30, 2016.

As of June 30, 2017, we had 59 instruments placed with customers under commercial agreements, compared to 46 instruments as of June 30, 2016. For the six months ended June 30, 2017, the average revenue per instrument placed under commercial agreements was approximately $75,000, compared to $79,000 for the six months ended June 30, 2016. This decrease was due to the timing of additional instrument placements towards the end of the second quarter in 2017. Our three largest customers, which each accounted for more than 10% of revenues, generated approximately $2.3 million of revenue in the six months ended June 30, 2017, compared to $2.2 million in the six months ended June 30, 2016.

Operating Expenses

Cost of Revenue

Cost of revenue increased by $0.2 million for the six months ended June 30, 2017, compared to the six months ended June 30, 2016.

Research and Development

Research and development expense decreased by $0.8 million, to $2.7 million for the six months ended June 30, 2017, from $3.5 million for the six months ended June 30, 2016. The decrease was primarily driven by a decrease in external development services of approximately $0.4 million, a $0.3 million decrease in payroll related expenses and a $0.1 million decrease in supplies.

Selling, General and Administrative

Selling, general and administrative expense decreased by $0.6 million, to $8.3 million for the six months ended June 30, 2017, from $8.9 million for the six months ended June 30, 2016. Payroll and travel related expenses decreased by approximately $0.4 million, depreciation decreased by approximately $0.1 million and promotional activities decreased by approximately $0.1 million. These decreases were partially offset by an increase of $0.1 million in consulting services.

Amortization of intangible assets

Amortization of intangibles was unchanged for the six months ended June 30, 2017 compared to the six months ended June 30, 2016.

Impairment of long-lived assets

During the six months ended June 30, 2017 we recognized an impairment of $11.6 million on certain long-lived assets including our intangible asset. No impairments were recorded during the six months ended June 30, 2016

Other (Expense) Income

Interest Income (Expense), net

Net interest expense decreased by $0.2 million to $0.6 million for the six months ended June 30, 2017, from net interest expense of $0.8 million for the six months ended June 30, 2016. The decrease was primarily due to the decreased principal outstanding during the six months ended June 30, 2017 compared to the six months ended June 30, 2016 as a result of additional principal payments.

Liquidity and Capital Resources

Prior to our IPO in July 2014, our operations were primarily financed through private sales of shares of our preferred stock and debt. Upon closing of our IPO on July 22, 2014 we received approximately $53.2 million of net proceeds, after deduction of underwriting discounts, commissions and expenses.  In October 2015, we filed a shelf registration statement with the Securities and Exchange Commission to register for sale any combination of the types of securities described in the filing up to an amount of $100 million. The shelf registration went effective on October 7, 2015, and to date no securities have been sold by us under this shelf registration. In September 2016, we closed a private placement stock offering in which we sold 22,500 shares of Series A Convertible Preferred Stock and five-year warrants to purchase an aggregate of approximately 3,214,299 shares of the Company’s common stock, at a purchase price of $1,000 per share of Preferred Stock. We received approximately $21.3 million in proceeds from the offering after deducting commissions and offering expenses.

We have incurred negative cash flows from operating and investment activities since our inception in 2009 and we expect to continue to incur negative cash flows from operating activities until we achieve a significant increase in our revenue. Since inception, we have devoted our resources to funding research and development and to commercializing the assets and technology acquired from Gen-Probe, as well as development of molecular chemistry and a small volume instrument. At June 30, 2017, we had cash and cash equivalents of $2.4 million and marketable securities of $9.0 million and an accumulated deficit of $233.5 million On August 16, 2017, the Company entered into the Asset Purchase Agreement, providing for the sale of substantially all of the assets of the Company. See “Item 5. Other Information.”

The following table shows a summary of our cash flows for the six months ended June 30, 2017 and 2016, respectively (amounts in thousands):

27

	Six Months Ended June 30,
	2017			2016
Net cash used in operating activities	$	(11,501	)	$	(12,604	)
Net cash provided by (used in) investing activities	6,932			20,547
Net cash provided by (used in) financing activities	(1,871		)	(2,472		)
Net increase / (decrease) in cash and cash equivalents	$	(6,440	)	$	5,471

Operating Activities

Net cash used in operating activities was $11.5 million for the six months ended June 30, 2017 and resulted from a $25.4 millionnet loss and $2.3 million net changes in operating assets and liabilities, partially offset by $16.1 million in non-cash items, principally depreciation and amortization, share-based compensation expense, provisions for inventory and non-cash interest expense.  Net cash used in operating activities was $12.6 million for the six months ended June 30, 2016 and resulted from an $15.7 millionnet loss and $1.7 million net changes in operating assets and liabilities, partially offset by $4.8 million in non-cash items, principally depreciation and amortization, share-based compensation expense and non-cash interest expense.

Investing Activities

Net cash provided by investing activities was $6.9 million for the six months ended June 30, 2017 and was primarily the result of maturities of marketable securities that were not reinvested. Net cash provided by investing activities was $20.5 million during the six months ended June 30, 2016 and was primarily the result of maturities of marketable securities that were not reinvested.

Financing Activities

Net cash used in financing activities was $1.9 million for the six months ended June 30, 2017 and consisted primarily of principal payments under our loan and security agreement with Comerica Bank of $1.0 million and payments to Gen-Probe for amounts deferred under our supply agreement of $0.8 million. Net cash used in financing activities for the six months ended June 30, 2016 was $2.5 million and consisted primarily of principal payments under our loan and security agreement with Comerica Bank of $2.0 million and payments to Gen-Probe for amounts deferred under our supply agreement of $0.5 million.

Operating Capital Requirements

We have limited capital resources, have experienced negative cash flows from operations and have incurred net losses since inception. We expect to continue to experience negative cash flows from operations and incur net losses in the near term as we devote substantially all of our efforts on commercialization of our products and continued product development. We expect future operating, investment and financing activities to be funded by our product revenue, our existing cash and cash equivalents, and from cash raised through the Asset Purchase Agreement. Based on our current business plan, we currently anticipate that we will have sufficient capital to fund remaining operations through the end of 2017. Our liquidity requirements will be negatively impacted if we are unable to close the Asset Sale, changes to our business plan, a lengthier sales cycle, lower demand for our products or other risks described elsewhere in this quarterly report and in our annual report on Form 10-K for the year ended December 31, 2016. Liquidity requirements through the end of 2017 include interest and principal payments on our outstanding debt and a payment to Gen-Probe of $2.5 million in August 2017. These factors create substantial doubt about our ability to continue as a going concern. Our liquidity requirements have and will continue to consist of sales, marketing, research and development expenses, capital expenditures, working capital and general corporate expenses. Our future liquidity requirements will also include general and administrative expenses, such as insurance costs and professional fees associated with being a public company.

Assuming stockholder approval of the Asset Sale and the plan of liquidation, liquidating distributions, in an amount to be determined, are expected to begin shortly after the completion of the Transition Period. The Company is analyzing the amount of liquidating distributions expected to be available for distribution to stockholders after payment of the Company’s liabilities, including the $2.5 million payment under the license agreement, repayment of the Company’s outstanding bank debt, the payment of expenses to be incurred for the operation of the business through the Transition Period, and the payment of expenses incurred in connection with the Asset Sale and winding down of the Company’s operations, and other liabilities incurred by the Company through such expected dissolution.

The Company cannot assure you that the conditions to the closing of the transactions contemplated by the Asset Purchase Agreement will be satisfied, or that the transactions will be completed. In the event the Company does not successfully complete the transactions contemplated by the Asset Purchase Agreement or complete a transaction resulting from a Superior Proposal, the

28

Company will have limited options for financing its ongoing operations and will likely cease its operations or file for bankruptcy protection.

These statements regarding our future liquidity requirements are forward-looking statements and involve risks and uncertainties and actual results could vary materially and negatively as a result of a number of factors, including the factors discussed in the section “Risk Factors” of this Form 10-Q and our most recent Annual Report on Form 10-K. We have based our estimates regarding our future liquidity requirements on assumptions that may prove to be wrong and we could utilize our available capital resources sooner than we currently expect.

Term Loan and Security Agreement

In November 2013, we entered into loan and security agreement with Comerica Bank ("Comerica").

Under the terms of the loan agreement with Comerica, we borrowed $5.0 million in November 2013. The Comerica loan bears interest at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 3.15 %, subject to a floor of the daily adjusting LIBOR rate plus 2.5%, which was 7.65% as of June 30, 2017.

In May 2015, we amended the Comerica Loan (the “Comerica Amendment”). The Comerica Amendment increased the borrowing under the Comerica Loan to $10.0 million, extended the interest-only period from June 1, 2015 until December 31, 2015 and extended the overall term by 12 months. In January 2016, we began making monthly payments which consist of accrued interest and equal principal payments in accordance with a 30-month amortization schedule.

Pursuant to the Comerica Amendment we were required to maintain at least $5.0 million of unrestricted cash and/or marketable securities with Comerica at all times. As of June 30, 2017 and during the period since we entered into the Comerica Amendment, we have been in compliance with this requirement. Additionally, the Comerica Loan contains various covenants that limit our ability to engage in specified types of transactions, including limiting our ability to; sell, transfer, lease or dispose of certain assets; engage in certain mergers and consolidations; incur debt or encumber or permit liens on certain assets, make certain restricted payments, including paying dividends on, or repurchasing or making distributions with respect to, our Common Stock; and enter into certain transactions with affiliates.

As of June 30, 2017, we had $5.0 million outstanding under the amended Comerica Loan. We may prepay the loan to Comerica, in full or in part at any time, provided that no event of default has occurred and is continuing.

In April 2017, we entered into a second amendment with Comerica (the "Second Amendment"). The Second Amendment provides for an interest only period for three months after which we will begin making monthly payments which consist of accrued interest and equal principal payments in accordance with a 15-month amortization schedule. The interest rate under the Second Amendment accrues at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 3.40%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%.

Pursuant to the Second Amendment, the amount of unrestricted cash and/or marketable securities we are required to maintain with Comerica at all times was reduced from $5.0 million to $4.0 million. In addition, the Second Amendment makes available to us a revolving line of credit of up to $4.0 million but not to exceed 80% of qualified receivables as defined in the Second Amendment. Borrowings under the revolving line of credit accrue interest at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 1.95%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%. Finally, we issued an additional warrant to Comerica to purchase up to an aggregate of 8,403 shares of Common Stock at $3.57 per share and modified the exercise price of the warrants previously granted to Comerica under the Comerica Loan and the first amendment to $3.57 per share.

Warrants

Warrants Issued prior to IPO

In connection with the Comerica Loan, and an additional loan and security agreement (the 'TriplePoint Loan") which was paid off in 2015, the Company issued warrants to purchase up to an aggregate of 352,941 shares of Series E preferred stock with an exercise price of $1.28. In connection with borrowings made under the TriplePoint Loan in March 2014, one of the warrants issued to TriplePoint became exercisable for an additional 156,863 shares of Series E. In connection with the IPO, the Series E warrants converted into warrants to purchase common stock at their conversion rate of approximately 0.0906 common warrant shares to one Series E warrant share. As a result, and subsequent to the reverse stock split conducted in October 2016, these warrants became exercisable for 4,618 shares of Common Stock with an exercise price of $140.80.

Warrants Issued Subsequent to IPO

29

In connection with the First Amendment to the Comerica Loan on May 29, 2015, and the Second Amendment to the Comerica Loan on April 6, 2017, we issued additional warrants to Comerica to purchase up to an aggregate of 5,227 shares and 8,403 shares, respectively. The warrants issued in connection with the Second Amendment, have an exercise price of $3.57 per share and the warrants issued to Comerica prior to the second amendment were modified in conjunction with the Second Amendment to have an exercise price of $3.57 per share.

In connection with the private placement offering noted above, we issued warrants to the investors (the "Investor Warrants") to purchase up to an aggregate of approximately 3,214,299 shares of the our Common Stock and warrants to the placement agent to purchase up to an aggregate of approximately 236,686 shares of the Company's Common Stock (the "Placement Warrants"). The Investor Warrants and Placement Warrants have an exercise price of $7.00 and expire five years from the date of issuance.

As of June 30, 2017, there are 3,469,233 warrant shares outstanding with a weighted average exercise price of $7.12 per share. The Comerica and TriplePoint warrants have the same piggyback registration rights as holders of registrable securities under the investors' rights agreement. Such rights will expire upon the earlier of (i) five years after our IPO and (ii) as to any holder, at such time as all registrable securities held by such holder may be sold without restriction under Rule 144.

Controlled Equity Offering^SM Sales Agreement

We entered into a Controlled Equity Offering^SM Sales Agreement (the "Sales Agreement"), dated October 30, 2015, with Cantor Fitzgerald & Co., as sales agent, pursuant to which we may offer and sell, from time to time, through Cantor Fitzgerald shares of our common stock for an aggregate offering price of up to $6,750,000, provided, however, that in no event shall we issue or sell through Cantor Fitzgerald such number or dollar amount of shares that exceed the number or dollar amount of shares permitted to be sold under Form S-3 (including General Instruction I.B.6 thereof). We are not obligated to sell any shares under the Sales Agreement. Subject to the terms and conditions of the Sales Agreement, Cantor Fitzgerald will use commercially reasonable efforts consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations and the rules of The NASDAQ Global Market to sell shares from time to time based upon our instructions, including any price, time or size limits specified by us. Under the Sales Agreement, we must pay Cantor Fitzgerald a commission of 3.0% of the aggregate gross proceeds from each sale of shares and reimburse Cantor Fitzgerald for certain specified expenses.  As of August 14, 2017, we had not sold any shares under this Sales Agreement, and we had $6.75 million remaining in aggregate offering price available under the Sales Agreement, provided, however, that in no event shall we issue or sell through Cantor Fitzgerald such number or dollar amount of shares that exceed the number or dollar amount of shares permitted to be sold under Form S-3 (including General Instruction I.B.6 thereof). 

Contractual Obligations and Commitments

For the six months ended June 30, 2017, there were no significant changes to our contractual obligations from those disclosed in our audited financial statements as of December 31, 2016, except for the amendment to our corporate office lease, which resulted in approximately $1.4 million of additional future commitments. Additional amounts due to the amendment are reflected in the table below. The following is a summary of our contractual obligations as of June 30, 2017 (in thousands):

	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Deferred payment obligations(1)	$	12,000	$	7,000	$	5,000	$	—	$	—
Operating lease obligations(2)	3,634		891		1,914		547		282
Purchase obligations(3)	575		575		—		—		—
Notes payable(4)	5,040		5,040		—		—		—
Total contractual obligations	$	21,249	$	13,506	$	6,914	$	547	$	282

(1) The deferred payment obligations are based upon the gross deferred amounts outstanding for instruments purchased from Gen-Probe as of June 30, 2017 as disclosed in the notes to our unaudited financial statements included elsewhere in this Form 10-Q. Such amounts are recorded at their aggregate present value of $1.9 million on the Balance Sheet as of June 30, 2017. The timing of when these payments are due reflects our current estimates of repayment. We do not believe that future revisions of estimates will have a significant impact on the timing of payments. Additionally, amounts due in less than one year includes the $5.0 million lump-sum payments payable to Gen-Probe on January 1, 2018 and amounts due beyond one year represent the $5.0 million lump-sum payment payable to Gen-Probe on January 1, 2020 in accordance with the amendment to our licensing agreement discussed in "Results of Operations". Such amounts are recorded at their present values of $4.8 million and $4.0 million as current and non-current liabilities, respectively, on the Balance Sheet as of June 30, 2017.

30

Amounts reflected in this table do not consider the reductions to the two $5.0 million lump-sum payments payable to Gen-Probe under the third license amendment entered into on August 16, 2017.

(2) Our operating lease obligations represent the contractual payments due for the lease of our corporate office in Warren, NJ and our facility in San Diego, CA.

(3) Our purchase obligations represent the total cost of instruments and supplies which we are committed to purchase from Gen-Probe as well as additional obligations due under other agreements entered into in the normal course of business. In accordance with the supply agreement with Gen-Probe, our purchases of Atlas instruments are defined in rolling quarterly forecasts, and these forecasts become binding commitments for approximately nine months of Atlas instrument purchases at any given time. Our obligation to purchase supplies from Gen-Probe is defined in an annual purchase order submitted in the third quarter of each year.

(4) Such amounts include the total principal outstanding at June 30, 2017 of $5.0 million and final payment fees of $0.04 million, of which approximately $4.0 million is due within one year from the Balance Sheet date. The remaining amounts are shown as being due in less than one year as our loan agreement contains a material adverse change clause which allows the lender to call the debt based on subjective factors regarding our business and performance. Amounts which are or may become payable as interest are excluded from the table, but are estimated to be approximately $0.1 million during the remainder of 2017.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under the rules and regulations of the Securities and Exchange Commission.

Critical Accounting Policies and Significant Estimates

We have prepared our financial statements in accordance with U.S. generally accepted accounting principles. Our preparation of these financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, expenses and related disclosures at the date of the financial statements, as well as revenue and expenses recorded during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from these estimates under different assumptions or conditions.

There have been no material changes to our critical accounting policies from those described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K.

31

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of June 30, 2017, our cash and cash equivalents of $2.4 million were primarily held in money market deposit accounts. Our primary exposure to market risk for our cash and cash equivalents is interest income sensitivity, which is affected by changes in the general level of U.S interest rates. However, because of the short-term nature of the instruments in our portfolio, a sudden change in the interest rates associated with these instruments is not expected to have a material impact on our financial condition or results of operations.

As of June 30, 2017, we had $9.0 million of marketable securities classified as held-to-maturity on our balance sheet which had a fair value of $17.5 million. As our intention is to hold these investments through maturity, any interest rate fluctuation changing the fair value of such marketable securities would only be realized if we sold the investments prior to maturity.

As of June 30, 2017, we had $5.0 million of variable interest-rate debt outstanding under the Amendment to the loan and security agreement with Comerica. Considering the amounts outstanding and the term of the loan and security agreement, we do not believe a 1.0% increase in the interest rate would have a material impact on our financial condition or results of operations.

We do not have any foreign currency or other derivative financial instruments.

ITEM 4. CONTROLS AND PROCEDURES

a) Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures.

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act) that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow 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. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

We continue the process of reviewing and documenting our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Our management, with the participation of the principal executive officer and principal financial officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this quarterly report. Based on this evaluation, the principal executive officer and principal financial officer concluded that these disclosure controls and procedures are effective at the reasonable assurance level.

b) Changes in Internal Control Over Financial Reporting.

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) identified in connection with the evaluation of our internal control performed during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

None.

Item 1A. RISK FACTORS

32

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K may not be the only risks facing the Company. Additional risks and uncertainties not currently known to the Company or that the Company currently deems to be immaterial also may materially adversely affect the Company’s business, financial condition and/or operating results.

There were no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 20, 2017 except as noted below.

There can be no guarantees that the Asset Sale will be completed and, if not completed, we may have to file for bankruptcy and liquidation.

        The consummation of the Asset Sale is subject to the satisfaction or waiver of various conditions, including the approval of the Asset Sale by our lender and our stockholders. We cannot guarantee that the closing conditions set forth in the Asset Purchase Agreement will be satisfied. If we are unable to satisfy the closing conditions in Buyer's favor or if other mutual closing conditions are not satisfied, Buyer will not be obligated to complete the Asset Sale. If the Asset Sale is not completed, our board of directors, in discharging its fiduciary obligations to our stockholders, will evaluate other strategic alternatives that may be available, which alternatives may not be as favorable to our stockholders as the Asset Sale and may include a bankruptcy and liquidation of the Company.

We cannot assure you the amount of liquidating distributions, if any, that will be made to our stockholders or the exact timing of distributions.

Our liquidation, dissolution and winding up process will be subject to uncertainties. The amount and timing of any liquidating distribution to our stockholders will depend on the following factors, among others:  

• Whether any potential claimants against us and currently unknown to us could present claims relating to our pre-dissolution operations that we may ultimately have to satisfy;

• The costs we may have to incur to defend new claims and claims existing as of the date of this proxy statement, including possible claims against us relating to our dissolution and possible tax audits;

• The payment of our outstanding bank debt and the $2.5 million under our license agreement;

• The payment of expenses to be incurred for the operation of the business through the Transition Period;

• The payment of expenses incurred in connection with the Asset Sale and our severance obligations;

• The amounts that we will need to pay for general administrative and overhead costs and expenses as an operating company before our dissolution and the amounts that we will need to pay in connection with our post-dissolution survival period;

• The costs attendant on us as a publicly held reporting company under SEC regulations, including legal and auditing fees, especially if we are unable to obtain relief from requirements to continue preparing and filing our annual, quarterly and current reports; and

• How much of our funds we will be required to reserve to provide for contingent liabilities, and how long it may take to finally determine whether and how much of those liabilities may have to be paid.

We will continue to incur expenses that will reduce any amounts available for distribution to our stockholders.

Claims, liabilities and expenses from operations, such as operating costs, salaries, directors’ and officers’ insurance, payroll and local taxes, legal, accounting and consulting fees and offices expenses will continue to be incurred by us as we wind down. We cannot estimate what the aggregate of these expenses will be, but they will reduce the amount of funds available for distribution to our stockholders.

33

Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Unregistered Sale of Equity Securities

In connection with the Second Amendment to the Loan Agreement, we issued an additional ten-year warrant to Comerica to purchase up to an aggregate of 8,403 shares of Common Stock at $3.57 per share and modified the exercise price of the warrants previously granted to Comerica under the Comerica Loan and the first amendment to $3.57 per share. The securities issued, as described above, have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and were made pursuant to the exemptions from registration provided by Section 4(a)(2) of the Securities Act. Such securities are therefore restricted in accordance with Rule 144 under the Securities Act.

Use of Proceeds

On July 16, 2014, our registration statement on Form S-1 (File No. 333-196135) was declared effective by the Securities and Exchange Commission for our initial public offering pursuant to which we sold an aggregate of 5,000,000 shares of our common stock at a price to the public of $12.00 per share. BofA Merrill Lynch and Leerink Partners acted as joint book-running managers for the offering. Cowen and Company and Wedbush PacGrow Life Sciences acted as co-managers. On July 22, 2014, we closed the sale of 5,000,000 shares, resulting in net proceeds to us of $53.2 million after deducting underwriting discounts and commissions and other offering expenses of $2.6 million. No payments were made by us to directors, officers or persons owning ten percent or more of our common stock or to their associates, or to our affiliates. As of June 30, 2017, we have used all $53.2 million of the net proceeds from our initial public offering, of which $8.0 million was paid to Gen-Probe pursuant to the terms of the second amendment to our license agreement with Gen-Probe and the remaining $45.2 million was used in operating activities including the commercialization of our Atlas Detection Assays and ongoing research and development activities. There has been no material change in the planned use of proceeds from our initial public offering as described in our final prospectus filed with the Securities and Exchange Commission on July 17, 2014 pursuant to Rule 424(b).

Issuer Repurchases of Equity Securities

None.

ITEM 5. OTHER INFORMATION

On August 16, 2017, the Company entered into the Amendment to its license agreement with Hologic. The Amendment provides that, among other things, the Company’s obligation to make milestone payments of $5.0 million in January 2018 and $5.0 million in January 2020 shall be reduced to a single $2.5 million milestone payment due in August 2017. In the event the Company fails to make such $2.5 million milestone payment to Hologic, the Buyer may be entitled to make the payment upon closing of the Asset Sale, in which case the purchase price payable to the Company at closing would be reduced by $2.5 million to $15.0 million.

On August 16, 2017, the Company entered into the Asset Purchase Agreement with the Buyer, providing for the sale of substantially all of the assets of the Company in an all-cash transaction for an aggregate purchase price of $17,500,000, subject to certain adjustments set forth in the Asset Purchase Agreement. IEH’s focus is to provide comprehensive risk management services to the food industry. In addition, the IEH family of companies is involved in the production and distribution of reagents, supplies, test kits and equipment to food testing laboratories and food companies. The IEH group operates in the U.S., Canada, Mexico, Germany, Austria, England, China and Australia.

Pursuant to the terms of the Asset Purchase Agreement, the Company is required to provide transition services to the Buyer for a period of time following the closing of the Asset Sale through the earlier of (i) December 31, 2017 and (ii) the date as of which the Company has provided Buyer with an aggregate of 900,000 assay tests (the “Transition Period”). IEH has guaranteed all obligations of Buyer under the Asset Purchase Agreement, including the obligation to pay the purchase price.

The closing of the Asset Sale is subject to certain customary conditions, including the receipt of consent of the Company’s lender and approval by the Company’s stockholders of the transactions contemplated by the Asset Purchase Agreement. As part of the transaction, the Company will be required to make a $2.5 million milestone payment pursuant to its license agreement with Hologic, Inc.

The Company may terminate the Asset Purchase Agreement under certain circumstances, including if its Board of Directors determines in good faith that it has received a Superior Proposal (as defined in the Asset Purchase Agreement) and that it is required to terminate the Asset Purchase Agreement in order to comply with its fiduciary duties, and otherwise complies with certain terms of the Asset Purchase Agreement.  In connection with such termination or a termination after the Company’s stockholders have approved the Asset Purchase Agreement, the Company must pay a termination fee of $770,000 to the Buyer.  In addition, the Asset Purchase Agreement contains certain other termination rights for the Company.

Assuming stockholder approval of the Asset Sale and a plan of liquidation, liquidating distributions, in an amount to be determined, are expected to begin shortly after the completion of the Transition Period. The Company is analyzing the amount of liquidating distributions expected to be available for distribution to stockholders after payment of the Company’s liabilities, including the $2.5 million payment under the license agreement, repayment of the Company’s outstanding bank debt, the payment of expenses to be incurred for the operation of the business through the Transition Period, and the payment of expenses incurred in connection with the Asset Sale and winding down of the Company’s operations, severance obligations, and other liabilities incurred by the Company through such expected dissolution.

The Company cannot assure you that the conditions to the closing of the transactions contemplated by the Asset Purchase Agreement will be satisfied, or that the transactions will be completed. In the event the Company does not successfully complete the transactions contemplated by the Asset Purchase Agreement or complete a transaction resulting from a Superior Proposal, the Company will have limited options for financing its ongoing operations and will likely cease its operations or file for bankruptcy protection.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Business Overview

BUSINESS OVERVIEW

Business

Roka Bioscience, Inc. (“Roka” or “the Company”) is focused on the development and commercialization of molecular assay technologies for the detection of foodborne pathogens. The Company was established in September 2009 through the acquisition of industrial testing assets and technology from Gen-Probe Incorporated, which was subsequently acquired by Hologic, Inc. (herein referred to as “Gen-Probe”).

The Company has limited capital resources, has experienced negative cash flows from operations and has incurred net losses since inception. The Company expects to continue to experience negative cash flows from operations and incur net losses in the near term as it devotes substantially all of its efforts on commercialization of its products and completion of its obligations under the asset purchase agreement discussed in Note 18. The Company’s business is subject to significant risks and its ability to successfully develop, manufacture and commercialize proprietary products is dependent upon many factors which include, but are not limited to, risks and uncertainties associated with materials, manufacturing scale-up, retention of key personnel, customer acceptance and competition. In addition, the Company’s debt agreement contains certain clauses which allow the lender to require repayment of the debt based on subjective factors regarding the Company’s business and performance, if those factors are considered a material adverse change by the lender.

On September 21, 2016, the Company closed a private placement in which it sold 22,500 shares of Series A Preferred Stock and 3,214,299 warrants to purchase Common Stock ("the Offering"). The Company received $21.3 million of net proceeds from the Offering after deducting placement agent fee and offering expenses, see Note 15 for further details.

On July 22, 2014, the Company completed an initial public offering ("IPO") in which it received $53.2 million of net proceeds from the offering after deducting underwriting discounts, commissions and offering expenses.

Going Concern

These financial statements have been prepared assuming that the Company will continue as a going concern. Based upon its current and projected cash flow, the Company notes there is substantial doubt about its ability to continue as a going concern within one year after the date that these financial statements are issued. The Company has entered into an asset purchase agreement for the sale of substantially all of its assets which is discussed in further detail in Note 18. The asset sale is the initial step in a contemplated liquidation of the Company. Liquidity requirements through the end of 2017 include interest and principal payments on the Company's outstanding debt and a payment to Gen-Probe of $2.5 million due in August 2017. The planned asset sale does not eliminate the substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty or any planned liquidation.

Concentration of Suppliers

The Company relies on single source suppliers, including Gen-Probe, for certain components and materials used in its products, including its Atlas Detection Assays. Since the Company’s contracts with these suppliers, including Gen-Probe, do not commit the suppliers to carry inventory or to make available any minimum quantities, the Company may be unable to obtain adequate supplies in a timely manner or on commercially reasonable terms.  If the Company loses such suppliers, or its suppliers encounter financial hardships, the Company may not be able to identify or enter into agreements with alternative suppliers on a timely basis on acceptable terms, if at all. Transitioning to a new supplier could be time consuming, may be expensive, may result in an interruption in the Company’s operations and could affect the performance specifications of the Company’s products. If the Company should encounter delays or difficulties in securing the quality and quantity of materials required for its products, the Company’s ability to manufacture its products would be interrupted which could adversely affect sales.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Roka Bioscience, Inc. have been prepared by the Company in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting, which do not conform in all respects to the requirements of U.S. GAAP for annual financial statements. The information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 20, 2017 (the “2016 Form 10-K”). Accordingly, these condensed consolidated notes to the unaudited financial statements should be read in conjunction with the 2016 audited financial statements and notes thereto prepared in accordance with U.S. GAAP. The unaudited financial statements have been prepared using accounting policies that are consistent with the policies used in preparing the Company’s audited financial statements for the year ended December 31, 2016. The condensed consolidated Balance Sheet as of December 31, 2016 was derived from the Company’s audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. The unaudited financial statements reflect all normal and recurring adjustments necessary, if any, for a fair statement of the Company’s financial position and results of operations for the interim periods presented. The results of operations for the six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 or for any other future annual or interim period. There have been no changes in the significant accounting policies from those included in the 2016 Form 10-K. However, in order to further clarify the Company's policy with respect to impairment of long-lived assets, below please find a description of such policy.

Impairment of Long-Lived Assets

The Company’s long-lived assets are primarily comprised of intangible assets and property, plant and equipment. The Company evaluates its finite-lived intangible assets and property, plant and equipment, for impairment whenever events or changes in circumstances indicate the carrying value of an asset or group of assets is not recoverable. If these circumstances exist, recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to future undiscounted cash flows expected to be generated by the asset group. If the Company’s estimated undiscounted future cash flows are below the asset group’s carrying value, the Company may recognize an impairment charge measured by its fair value. See Note 7 for further details.

Reverse Stock Split

In June 2016, the Company's shareholders approved an amendment to the Company's certificate of incorporation and grant of discretionary authority to the Board of Directors to effect a reverse stock split. On October 11, 2016, the Company's Board of Directors effected a 10:1 reverse stock split of the Company's Common Stock. In addition, effective on the date of the reverse stock split, the conversion price of the Company's Preferred Stock sold in the Offering detailed in Note 1 was adjusted proportionately, and consequently each share of such Preferred Stock became convertible into approximately 143 shares of Common Stock. Unless otherwise noted, the Company’s historical share and per share information have been retroactively adjusted as if such stock split and corresponding change in conversion ratio occurred on the first day of the first period presented.

Prior Period Corrections

Previously, the Company included approximately $3.3 million in Other current assets and Accruedexpenses and other current liabilities related to the settlement amount for the class action lawsuit filed against the Company. The amount in Other current assets represented the expected reimbursement from the Company's insurance provider and the amount in Accrued expenses and other current liabilities was determined based upon the proposed settlement amount. During April 2017, the Company received additional information regarding the status of the litigation which indicated the Company's insurance provider disbursed the settlement amount and the settlement amount was finalized by the court as of December 31, 2016. As such, the Company has revised the December 31, 2016 balance sheet as indicated in the table below.

	As of December 31, 2016
	As previously reported	Change		As revised
Prepaid expenses and other current assets	5,614	(3,275	)	2,339
Total current assets	35,116	(3,275	)	31,841
Total assets	61,836	(3,275	)	58,561
Accrued expenses and other current liabilities	5,847	(3,275	)	2,572
Total current liabilities	15,067	(3,275	)	11,792
Total liabilities	24,954	(3,275	)	21,679
Total liabilities and stockholders' equity	61,836	(3,275	)	58,561

Additionally, the Company made the following corrections to the amounts presented in the Accrued expenses footnote below.

	As of December 31, 2016
	As previously reported	Change		As revised
Other	3,658	(3,275	)	383
Total accrued expenses	5,847	(3,275	)	2,572

The Company believes these corrections are not material to any previously issued financial statements and further notes these adjustments have no impact on the 2016 Consolidated Statement of Operations and Comprehensive Loss, the Consolidated Statement of Convertible Preferred Stock Stockholders' Equity (Deficit), or the net amounts presented in the Consolidated Statement of Cash Flows for the year ended December 31, 2016.

New Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies and adopted by the Company as of the specified effective date.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. This standard clarifies the treatment of specific cash flow issues in order to reduce existing diversity in practice. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not believe this new guidance will have a material impact on its financial statements.

In February 2016, the FASB issued ASU 2016-02, creating Topic 842, Leases which supersedes the guidance in former ASC 840, Leases, to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. The Company is currently in the process of evaluating the impact this new guidance will have on its financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This standard outlines a single comprehensive revenue recognition model for all contracts with customers and supersedes current revenue recognition guidance. The revenue standard contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of control of goods or services to its customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The new standard also includes enhanced disclosure requirements. During 2016, the FASB issued several accounting updates (ASU No. 2016-08, 2016-10 and 2016-12) to clarify implementation guidance and correct unintended application of the guidance. ASU 2014-09 provides companies with two implementation methods, companies can choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). The Company plans to adopt the new standard on January 1, 2018, using the “modified retrospective” method. The Company continues to make progress in its assessment and implementation of the new standard, however, completion of this assessment is still ongoing, and as such, the Company has not yet determined if the new standard will have a material impact on its revenue recognition accounting policy or its Consolidated Financial Statements.

Adoption of New Accounting Principle

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. The standard requires entities to classify all deferred tax assets and liabilities as noncurrent. The standard became effective for interim and annual periods beginning after December 15, 2016. The Company adopted this new guidance beginning with the annual period beginning January 1, 2017. No adjustments were required to be made to the financial statements as a result of the Company's adoption of this new guidance.

Intangible Assets

INTANGIBLE ASSETS

In June 2014, the Company entered into a second amendment to its license agreement with Gen-Probe (the "Second License Amendment"). Under the Second License Amendment, the Company obtained a two-year option to reduce the royalty rate it pays to Gen-Probe in exchange for an option payment of $2.5 million. Upon completion of its IPO in July 2014, the Company exercised its option and issued to Gen-Probe 865,063 shares of common stock valued at $10.51 per share on the issuance date and made a cash payment of $8.0 million. Under the Second License Amendment, the Company is required to make additional cash payments of $5.0 million on January 1, 2018 and $5.0 million on January 1, 2020. These payment terms were modified under a third amendment (the "Third License Amendment") entered into on August 16, 2017, see note 18 for additional details.

The aggregate cash and stock payments made to Gen-Probe along with the present value of the two$5.0 million payments described above were recorded as a $26.6 million addition to the Company's intangible technology asset in Intangible assets on the Balance Sheet and will be amortized on a straight-line basis through the end of the estimated remaining life of the technology asset. See Note 9 for further details on the additional required future cash payments described above.

Pursuant to the terms of the Second License Amendment, the Company committed to additional future contingent payments, as described in Note 11 below. If made, such additional payments will further reduce the royalty rate the Company pays to Gen-Probe, and will be recorded as additions to the Company's intangible technology asset upon payment and amortized over the estimated remaining life of the technology asset.

The Company assesses its intangible and other long-lived assets for impairment whenever events or other changes in circumstances suggest that the carrying value of an asset group may not be recoverable based on its undiscounted future cash flows. If the Company’s estimated undiscounted future cash flows are below the asset group’s carrying value, the Company may recognize an impairment charge measured by its fair value.

During the second quarter of 2017, due to revenues and customer acquisitions falling below the Company's previous projections, the Company prepared revised projections for revenue and expenses. Compared to the Company's previous projections, the revised projections indicated reduced revenue from sales of the Company's products, expected to result in continued and increased cash flow losses for the Company. Additionally, a decision was made to pursue a sale of the Company or its assets.

Based on these facts and events described above, the Company determined a triggering event had occurred, requiring an assessment of whether the asset group was impaired as of June 30, 2017. In addition, the Company determined the assets did not qualify for held-for-sale as of June 30, 2017 and as such the impairment analysis was performed under the held-for-use guidance.

The Company completed its assessment of the asset group, which includes the intangible asset, for recoverability. The recoverability assessment was based upon probability-weighted cash flow estimates resulting from updated revenue and expense projections. Based on the cash flow projections associated with the asset group, the Company determined that the asset group was impaired as of June 30, 2017. The Company subsequently determined the fair value of the asset group, considering the present value of future cash flows from a potential liquidation scenario as well as estimates of fair value based on an asset sale scenario.

Based on the impairment assessment, the Company determined that the fair value of the asset group, including the intangible asset, was $11.5 million as of June 30, 2017, and the Company recognized an impairment of $8.5 million on the intangible asset and an impairment of $3.2 million on fixed assets included in the asset group during the three months ended June 30, 2017. Further, as of June 30, 2017, the Company reduced the estimated remaining life of the intangible asset and related fixed assets to three months, based upon the most likely scenario used in the impairment analysis.

Deferred Payments

DEFERRED PAYMENTS

Gen-Probe supply agreement

In May 2011, the Company entered into a supply agreement with Gen-Probe to purchase Atlas instruments. Pursuant to the terms of the agreement, the Company can defer up to one half of the purchase price for up to 54 months from the date of delivery. The deferred amounts do not bear interest, and the Company has recorded the imputed interest component as a reduction of the deferred payment and as a reduction of the asset cost. The supply agreement provides for variable repayment terms based on a percentage of net sales as defined in the agreement, and the Company has estimated its net sales in determining amounts due for the 54 month term. The following table summarizes the amounts deferred under this agreement (amounts in thousands):

	As of June 30,			As of December 31,
	2017			2016
Current
Deferred payments, gross	$	2,000		$	2,076
Imputed interest	(62		)	(154		)

Long-term
Deferred payments, gross	$	—		$	1,136
Imputed interest	—			(8		)
Deferred payments, net	$	—		$	1,128

The Company estimated the interest rate implicit in the extended payment terms by considering the rate at which it could obtain financing of a similar nature from other sources at the date of each transaction, as well as prevailing rates for similar debt instruments of issuers with similar credit ratings. The estimated effective interest rate used ranges from 9.9% to 11.2%.

In the three and six months ended June 30, 2017, the Company recorded approximately $0.04 million and $0.1 million, respectively, and in the three and six months ended June 30, 2016, the Company recorded approximately $0.1 million and $0.2 million, respectively as non-cash interest expense related to the deferred payments pursuant to the supply agreement with Gen-Probe.

Gen-Probe license amendment

The Second License Amendment to the license agreement with Gen-Probe detailed in Note 7 includes a $5.0 million payment due on January 1, 2018 and a $5.0 million payment due on January 1, 2020. Under the terms of the Second License Amendment, no interest payments are required and no interest rate is stated. The Company determined that imputed interest should be calculated and recognized in accordance with ASC-835, and the payments are recorded in Deferred payments on the Balance Sheet at their present value based upon a 7.6% interest rate for the payment due on January 1, 2018 and a 9.0% interest rate for the payment due on January 1, 2020. The difference between the present value and the amount payable is accreted to Deferred payments over the respective term with a corresponding charge to Interest expense. Pursuant to the Third License Amendment, which was entered into with Gen-Probe on August 16, 2017, the two payments of $5.0 million were reduced to one single payment of $2.5 million due in 2017. See Note 18 for further details.

Debt Disclosure [Abstract]

Notes Payable

NOTES PAYABLE

In November 2013, the Company entered into a loan and security agreement (the 'Comerica Loan") with Comerica Bank (“Comerica”) in which it borrowed $5.0 million. The interest under the loan accrues at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 3.15%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%. As of June 30, 2017, the rate was 7.65%. Additionally, the Comerica Loan contains various covenants that limit the Company’s ability to engage in specified types of transactions, including limiting the Company’s ability to; sell, transfer, lease or dispose of certain assets; engage in certain mergers and consolidations; incur debt or encumber or permit liens on certain assets, make certain restricted payments, including paying dividends on, or repurchasing or making distributions with respect to, the Company’s Common Stock; and enter into certain transactions with affiliates. The Company has been in compliance with all requirements since originally entering into the Comerica Loan.

In May 2015, the Company amended the loan and security agreement with Comerica (the “First Amendment”). The Comerica Amendment increased the borrowing under the Comerica Loan to $10.0 million and extended the interest-only period until December 31, 2015. Beginning January 1, 2016, the Company began making monthly payments which consist of accrued interest and equal principal payments in accordance with a 30-month amortization schedule.

In April 2017, the Company entered into a second amendment with Comerica (the "Second Amendment"). The Second Amendment provides for an interest only period for three months after which the Company will begin making monthly payments which consist of accrued interest and equal principal payments in accordance with a 15-month amortization schedule. The interest rate under the Second Amendment accrues at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 3.40%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%. In connection with the Second Amendment, the Company issued an additional warrant to Comerica to purchase up to an aggregate of 8,403 shares of Common Stock at $3.57 per share and modified the exercise price of the warrants previously granted to Comerica under the Comerica Loan and the first amendment to $3.57 per share. The value of the new warrant and the incremental value due to the amendment of the previously issued warrants were recorded as a reduction to Notes payable with a corresponding offset to Additional paid-in capital. The value of the new warrant and the incremental value due to the modified pricing of the existing Comerica warrants were recorded as a reduction to Notes payable with a corresponding offset to Additional paid-in capital, see Note 15 for further details.

In connection with the Comerica Loan and the two amendments, the Company recorded the note net of expenses paid to Comerica, the value of the warrants issued to Comerica and the incremental value due to the amendment of the warrants at the time of the repricing. The difference between the liability recorded and the face value of the note will be accreted to Notes payable over the term of the loan with a corresponding charge to Interest expense.

Pursuant to the Second Amendment, the amount of unrestricted cash and/or marketable securities the Company is required to maintain with Comerica at all times was reduced from $5.0 million to $4.0 million. The Company has been in compliance with these requirements since implemented. In addition, the Second Amendment makes available to the Company a revolving line of credit of up to $4.0 million but not to exceed 80% of qualified receivables as defined in the Second Amendment. Borrowings under the revolving line of credit accrue interest at Comerica’s Prime Referenced Rate (as defined in the loan agreement with Comerica) plus 1.95%, subject to a floor of the daily adjusting LIBOR rate plus 2.5%.

As of June 30, 2017, the entire remaining balance of $5.0 million has been classified as Notes payable, current on the Balance Sheet, although only $4.0 million is due within one year. The remaining $1.0 million has also been classified as Notes payable, current because the Comerica Loan agreement contains a material adverse change clause which allows Comerica to require repayment of the debt based on subjective factors regarding the Company’s business and performance.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Operating Leases

In April 2017, the Company amended the lease for its Warren, NJ laboratory and office space. The amendment provides for the termination of the lease of laboratory space and for extending the lease on office space through June 2023. The termination and extension resulted in additional future commitments of approximately $1.4 million. There have been no other significant changes to the Company’s operating leases as disclosed in the Company’s most recent audited financial statements.

Commitments

During the six months ended June 30, 2017, there have been no significant changes to the Company’s commitments as disclosed in the Company’s most recent audited financial statements except as it relates to the reduction in commitments under the Third License Amendment entered into with Gen-Probe on August 16, 2017 previously noted. See Note 18 for further details.

Contingent liabilities

In addition to the commitments disclosed in the Company’s most recent audited financial statements, the Second License Amendment to the license agreement with Gen-Probe detailed in Note 9 provided for additional milestone payments of up to $6.0 million which will further reduce the royalty rate paid. Such payments were removed under the terms of the Third License Amendment entered into on August 16, 2017. See Note 18 for further details.

Legal Matters

The Company may periodically become subject to legal proceedings and claims arising in connection with its business. Except as set forth below, the Company is not currently involved in any legal proceedings, nor are any claims pending against the Company.

A putative securities class action originally captioned Ding v. Roka Bioscience, Inc., Case No. 3:14-cv-8020, was filed against the Company and certain of its officers and directors in the United States District Court for the District of New Jersey on December 24, 2014, on behalf of a putative class of persons and entities who had purchased or otherwise acquired securities pursuant or traceable to the Registration Statement for the Company’s IPO. The original putative class period ran from July 17 through November 6, 2014.  The original complaint asserted claims under the Securities Act of 1933 and contended that the IPO Registration Statement was false and misleading, or omitted allegedly material information, in connection with the Company’s statements about its placement of Atlas instruments and its expectations of future growth and increased market share, and the Company’s alleged failure to disclose “known trends and uncertainties about the Company’s sales.”  The alleged misrepresentations and omissions purportedly came to light when the Company issued its third-quarter 2014 earnings release on November 6, 2014.

Pursuant to the Private Securities Litigation Reform Act of 1995, the court appointed Stanley Yedlowski as lead plaintiff and The Rosen Law Firm as lead counsel on April 21, 2015. The lead plaintiff then filed an amended complaint, captioned Stanley Yedlowski v. Roka Bioscience, Inc., Case No. 14-cv-8020, on June 23, 2015. The amended complaint pled Securities Act claims on behalf of persons and entities who had purchased or otherwise acquired Roka securities pursuant or traceable to the IPO Registration Statement during an extended putative class period, running from July 17, 2014 through March 26, 2015. The amended complaint alleged that the Registration Statement was false or misleading in that it failed to disclose that the Company’s customers purportedly were experiencing false positives and other usage issues with the Company’s Listeria assays apparently arising from the customers’ employees’ inability to follow the Company’s Listeria assay workflow. The amended complaint alleged that the full extent of the purported misstatements and omissions was not revealed until March 26, 2015. Defendants filed a motion on August 25, 2015 to dismiss the amended complaint, and plaintiffs filed an opposition to that motion on October 9, 2015. The parties entered into a settlement agreement, which was approved by the court in December 2016, to pay approximately $3.3 million. As of June 30, 2017, all payments have been made in accordance with the settlement agreement and the corresponding receivable and liability are no longer recorded on the Company's Balance Sheet.

The Company sells its products in various jurisdictions and is subject to federal, state and local taxes including, where applicable, sales and use tax. While the Company believes that it has properly paid or accrued for all such taxes based on its interpretation of applicable law, tax laws are complex and interpretations differ. Periodically, the Company may be audited by taxing authorities, and it is possible that additional assessments may be made in the future.

Fair Value Measurements

FAIR VALUE MEASUREMENTS

The Company’s financial instruments consist of cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable, short-term deferred payments, deferred payments, notes payable, accrued expenses and Convertible Preferred Stock Warrants. The carrying amounts of cash and cash equivalents, trade accounts receivable, accounts payable, short-term deferred payments and accrued expenses approximate their fair values because of the short-term nature of the instruments, or, in the case of the deferred payments and notes payable, because the interest rates the Company believes it could obtain for similar borrowings is similar to its existing interest rates.  The carrying amount of the Company's marketable securities is the amortized cost basis based upon their held-to-maturity classification.

In addition to the above noted financial instruments, as discussed in Note 7, the Company's intangible asset and certain fixed assets have been impaired during the three months ended June 30, 2017 and are recorded at approximate fair market value as of that date.

The following table summarizes the fair value information for the Company’s cash held in money market deposit accounts and its marketable securities at June 30, 2017 and December 31, 2016 (amounts in thousands):

A portion of the Company’s cash and cash equivalents are held in money market deposit accounts and a portion of the Company's short-term marketable securities are United States treasury bills, each of which are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices.

The Company's short-term marketable securities not classified within Level 1 of the fair value hierarchy are comprised of commercial paper, U.S. government-related debt, and corporate debt securities, all of which are classified as  Level 2 within the fair value hierarchy. The Company estimates the fair values of these marketable securities by taking into consideration valuations obtained from its investment manager, which utilizes industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. There have been no transfers between levels during the reporting period.

Equity [Abstract]

Convertible Preferred Stock and Stockholders' Equity (Deficit)

Authorized stock

In connection with the seventh amended and restated certificate of incorporation effective on July 22, 2014, the total authorized shares of stock was changed to 520,000,000 of which 500,000,000 shares are designated as common stock with a par value of $0.001 per share and 20,000,000 shares are designated as "blank check" preferred stock with a par value of $0.001 per share.

Convertible Preferred Stock

On September 21, 2016, the Company closed a private placement offering (the "Offering") in which it issued and sold 22,500 shares of Series A Preferred Stock ("Preferred Stock") and five-year warrants (the "Investor Warrants") to purchase an aggregate of 3,214,299 shares of the Company’s Common Stock, par value $0.001 (the “Warrant Shares”) at a purchase price of $1,000 per share of Preferred Stock for aggregate gross proceeds of $22.5 million. The shares of Preferred Stock were convertible into common stock at a conversion rate of $7.00 per share of Common Stock and were immediately convertible at the option of the holder up to the holder's pro-rata share of 19.999% of the Company's Common Stock outstanding on the closing date of the Offering. All shares of Preferred Stock not previously converted were converted to Common Stock automatically upon shareholder approval which was obtained at a special shareholder meeting held on November 10, 2016.

Registration rights

Holders of approximately 0.8 million shares of the Company's outstanding Common Stock have rights, subject to certain conditions, to require that the Company file a registration statement under the Securities Act covering the registration of such shares of Common Stock, as well as piggyback registration rights. These rights are provided under the terms of an investor rights agreement between the Company and the holders of the registrable securities, which will expire upon the earlier of (i) five years after the Company's IPO and (ii) as to a holder, at such time as all registrable securities held by such holder may be sold without restriction under Rule 144.

In connection with the Offering, on September 21, 2016, the Company entered into a registration rights agreement which provides that the Company would prepare and file with the U.S. Securities and Exchange Commission (the “SEC”), a resale shelf registration statement covering the Conversion Shares and Warrant Shares. Accordingly, on October 7, 2016, the Company filed an S-3 registration statement which was declared effective on October 24, 2016 enabling registration of the Conversion Shares and the Warrant Shares. The Company is required to maintain the effectiveness of such registration statement until the earlier of: (i) the date that all registrable securities covered by such registration statement have been sold, thereunder or pursuant to Rule 144 or (ii) the date that all registrable securities covered by such registration statement may be sold without limitation pursuant to Rule 144 (the “Effectiveness Period”). Subject to certain exceptions set forth in the registration rights agreement, if the Company fails to maintain the effectiveness of the registration statement during the Effectiveness Period, the Company will be required to pay to each holder an amount in cash equal to the product of 1.5% multiplied by the aggregate purchase price paid by such holder pursuant to the securities purchase agreement, subject to a cap equal to 10.0% of the aggregate purchase paid by such holder pursuant to the securities purchase agreement.

Stock-Based Compensation

STOCK-BASED COMPENSATION

Effective upon the closing of the IPO, the Company adopted the Roka Bioscience, Inc. 2014 Equity Incentive Plan (the "2014 Plan"). The 2014 Plan initially made available 108,695 shares to be granted to employees, officers, directors, consultants, advisors or other individual service providers of the Company. On February 28, 2017, the Company held a special shareholder meeting at which the shareholders voted to increase the total number of shares available under the 2014 Plan to 665,340. Additionally, the amended plan provides for automatic increases on January 1st of each year for a period of ten years commencing on January 1, 2018 and ending on (and including) January 1, 2027, in an amount equal to 3% of the total number of shares of Common Stock outstanding on December 31st of the preceding calendar year.

Under the Roka Bioscience, Inc. 2009 Equity Incentive Plan (the “2009 Plan”), as amended on June 13, 2013, incentive and non-qualified stock options and restricted stock may be granted for up to a maximum of 202,885 shares to employees, consultants and directors of the Company. Effective upon adoption of the 2014 Plan, the Company has not and does not intend to issue additional shares under the 2009 Plan.

Stock options and shares of restricted stock granted under the 2009 Plan and the 2014 Plan have a maximum contractual term of ten years from the date of grant and generally vest over four years. For stock options, the exercise price may not be less than the fair value of the stock on the grant date.

The Company recognized stock compensation expense as follows (amounts in thousands):

	For the Three Months Ended   June 30,				For the Six Months Ended June 30,
	2017		2016		2017		2016
Stock options	$	125	$	170	$	229	$	380
Restricted stock	$	231	$	185	$	395	$	370

The Company granted approximately 411,000 stock options and 5,000 shares of restricted stock during the six months ended June 30, 2017, valued at approximately $1.0 million and $0.02 million, respectively. The Company granted approximately 100,000 stock options and 2,500 shares of restricted stock, valued at $0.6 million and $0.01 million, respectively, during the six months ended June 30, 2016.

The Company determines the fair value of stock option awards at the date of grant using a Black-Scholes valuation model. This model requires the Company to make assumptions and judgments on the expected volatility, dividend yield, the risk-free interest rate and the expected term of the stock options. The following ranges of assumptions were utilized for stock options granted during the periods indicated:

	For the Six Months Ended June 30,
	2017	2016
Expected life in years	5.5-6.2	5.5-6.2
Interest rate	1.86%-2.11%	1.27%-1.92%
Volatility	85% - 89%	80% - 88%
Dividend yield	—	—

The Company estimates the expected life of its employee stock options using the “simplified” method, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the option due to its lack of sufficient historical data. The risk-free interest rates are based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The expected stock price volatility rates are based on average historical volatilities of the common stock of the Company and a group of public companies in similar industries. The Company has no history or expectations of paying dividends on its Common Stock and therefore uses a zero percent dividend yield in the Black-Scholes option pricing model.

Warrants

WARRANTS

As of June 30, 2017, there were 3,469,233 warrant shares outstanding with a weighted average exercise price of $7.12 per share.

Warrants Issued prior to IPO

In connection with the closing of the loan and security agreement in November 2013 discussed in Note 10, and an additional loan and security agreement (the 'TriplePoint Loan") which was paid off in 2015, the Company issued warrants to purchase up to an aggregate of 352,941 shares of Series E preferred stock with an exercise price of $1.28. Upon issuance, the Company recorded liabilities of approximately $0.08 million for the warrants issued. The initial fair value of the warrant issued to Comerica of approximately $0.03 million was deemed a discount on the debt issued by Comerica and is being accreted to interest expense over the term of the Comerica Loan. The initial fair value of the remaining warrants issued were capitalized in Other assets on the Balance Sheet as part of debt issuance costs and were amortized to Interest expense. In connection with borrowings made under the TriplePoint Loan in March 2014, one of the warrants issued to TriplePoint became exercisable for an additional 156,863 shares of Series E. The related fair value of approximately $0.1 million was deemed a discount on the debt issued at that time and was accreted to interest expense through the payoff of the loan in May 2015. In connection with the IPO, the Series E warrants converted into warrants to purchase common stock at their conversion rate of approximately 0.0906 common warrant shares to one Series E warrant share. As a result, and subsequent to the reverse stock split conducted in October 2016, became exercisable for 4,618 shares of Common Stock with an exercise price of $140.80.

Earnings Per Share [Abstract]

Net Loss per Share

NET LOSS PER SHARE

Basic net loss per share is calculated by dividing net loss applicable to common stockholders by the weighted-average shares outstanding during the period, without consideration for common stock equivalents. The weighted-average common shares outstanding excludes unvested restricted stock which although such shares are legally issued and outstanding, are not required to share in losses of the Company and are therefore excluded from the net loss per share calculation. Diluted net loss per share is calculated by adjusting the weighted-average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. For purposes of the diluted net loss per share calculation, stock options and warrants are considered to be common stock equivalents but are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.

	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2017			2016			2017			2016
Net loss applicable to common shareholders (thousands)	$	(17,754	)	$	(7,560	)	$	(25,358	)	$	(15,736	)

Basic and diluted loss per share	$	(3.56	)	$	(4.31	)	$	(5.09	)	$	(8.98	)

As the Company incurred a loss for the three and six months endedJune 30, 2017 and 2016, all unvested restricted stock awards were excluded from the calculation of basic net loss per share and all potential Common Stock shares issuable for stock options and warrants were excluded from the calculation of diluted net loss per share, as the effect of including them would have been anti-dilutive. Had the Company not incurred a loss, the dilutive effect of the unvested restricted stock awards on basic weighted average common shares outstanding and the dilutive effect of potential Common Stock shares issuable for stock options and warrants on the weighted-average number of Common Stock shares outstanding would have been as follows:

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

Subsequent Events

SUBSEQUENT EVENTS

On August 16, 2017, the Company entered into a definitive agreement (the “Asset Purchase Agreement”) with Rokabio, Inc. (the “Buyer”), a newly formed subsidiary of Institute for Environmental Health (“IEH” or the “Buyer”), providing for the sale of substantially all of the assets of the Company in an all-cash transaction for an aggregate purchase price of $17.5 million, subject to certain adjustments set forth in the Asset Purchase Agreement (the “Asset Sale”).

On August 16, 2017, the Company entered into the Third License Amendment with Gen-Probe. The Third License Amendment provides that, among other things, the Company’s obligation to make milestone payments of $5.0 million on January 1, 2018 and $5.0 million on January 1, 2020 shall be reduced to a single $2.5 million milestone payment payable in August 2017. In the event the Company fails to make such $2.5 million milestone payment to Hologic, the Buyer may be entitled to make the payment upon closing of the Asset Sale, in which case the purchase price payable to the Company at closing would be reduced by $2.5 million to $15.0 million.

Pursuant to the terms of the Asset Purchase Agreement, the Company is required to provide transition services to the Buyer for a period of time following the closing of the Asset Sale through the earlier of (i) December 31, 2017 and (ii) the date as of which the Company has provided Buyer with an aggregate of 900,000 assay tests (the “Transition Period”). IEH has guaranteed all obligations of Buyer under the Asset Purchase Agreement, including the obligation to pay the purchase price.

The closing of the Asset Sale is subject to certain customary conditions, including the receipt of consent of the Company’s lender and approval by the Company’s stockholders of the transactions contemplated by the Asset Purchase Agreement. As part of the transaction, the Company will be required to make a $2.5 million milestone payment pursuant to its license agreement with Hologic, Inc.

The Company may terminate the Asset Purchase Agreement under certain circumstances, including if its Board of Directors determines in good faith that it has received a Superior Proposal (as defined in the Asset Purchase Agreement) and that it is required to terminate the Asset Purchase Agreement in order to comply with its fiduciary duties, and otherwise complies with certain terms of the Asset Purchase Agreement.  In connection with such termination or a termination after the Company’s stockholders have approved the Asset Purchase Agreement, the Company must pay a termination fee of $770,000 to the Buyer.  In addition, the Asset Purchase Agreement contains certain other termination rights for the Company.

Assuming stockholder approval of the Asset Sale and the plan of liquidation, liquidating distributions, in an amount to be determined, are expected to begin shortly after the completion of the Transition Period. The Company is analyzing the amount of liquidating distributions expected to be available for distribution to stockholders after payment of the Company’s liabilities, including the $2.5 million payment under the license agreement, repayment of the Company’s outstanding bank debt, the payment of expenses to be incurred for the operation of the business through the Transition Period, and the payment of expenses incurred in connection with the Asset Sale and winding down of the Company’s operations, and other liabilities incurred by the Company through such expected dissolution.

The Company cannot assure you that the conditions to the closing of the transactions contemplated by the Asset Purchase Agreement will be satisfied, or that the transactions will be completed. In the event the Company does not successfully complete the transactions contemplated by the Asset Purchase Agreement or complete a transaction resulting from a Superior Proposal, the Company will have limited options for financing its ongoing operations and will likely cease its operations or file for bankruptcy protection.

Accounting Policies [Abstract]

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Roka Bioscience, Inc. have been prepared by the Company in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting, which do not conform in all respects to the requirements of U.S. GAAP for annual financial statements. The information included in this quarterly report on Form 10-Q should be read in conjunction with the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 20, 2017 (the “2016 Form 10-K”). Accordingly, these condensed consolidated notes to the unaudited financial statements should be read in conjunction with the 2016 audited financial statements and notes thereto prepared in accordance with U.S. GAAP. The unaudited financial statements have been prepared using accounting policies that are consistent with the policies used in preparing the Company’s audited financial statements for the year ended December 31, 2016. The condensed consolidated Balance Sheet as of December 31, 2016 was derived from the Company’s audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. The unaudited financial statements reflect all normal and recurring adjustments necessary, if any, for a fair statement of the Company’s financial position and results of operations for the interim periods presented. The results of operations for the six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 or for any other future annual or interim period. There have been no changes in the significant accounting policies from those included in the 2016 Form 10-K.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

The Company’s long-lived assets are primarily comprised of intangible assets and property, plant and equipment. The Company evaluates its finite-lived intangible assets and property, plant and equipment, for impairment whenever events or changes in circumstances indicate the carrying value of an asset or group of assets is not recoverable. If these circumstances exist, recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to future undiscounted cash flows expected to be generated by the asset group. If the Company’s estimated undiscounted future cash flows are below the asset group’s carrying value, the Company may recognize an impairment charge measured by its fair value.

New Accounting Pronouncements

New Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies and adopted by the Company as of the specified effective date.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. This standard clarifies the treatment of specific cash flow issues in order to reduce existing diversity in practice. The standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company does not believe this new guidance will have a material impact on its financial statements.

In February 2016, the FASB issued ASU 2016-02, creating Topic 842, Leases which supersedes the guidance in former ASC 840, Leases, to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. The Company is currently in the process of evaluating the impact this new guidance will have on its financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This standard outlines a single comprehensive revenue recognition model for all contracts with customers and supersedes current revenue recognition guidance. The revenue standard contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of control of goods or services to its customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The new standard also includes enhanced disclosure requirements. During 2016, the FASB issued several accounting updates (ASU No. 2016-08, 2016-10 and 2016-12) to clarify implementation guidance and correct unintended application of the guidance. ASU 2014-09 provides companies with two implementation methods, companies can choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). The Company plans to adopt the new standard on January 1, 2018, using the “modified retrospective” method. The Company continues to make progress in its assessment and implementation of the new standard, however, completion of this assessment is still ongoing, and as such, the Company has not yet determined if the new standard will have a material impact on its revenue recognition accounting policy or its Consolidated Financial Statements.

Adoption of New Accounting Principle

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. The standard requires entities to classify all deferred tax assets and liabilities as noncurrent. The standard became effective for interim and annual periods beginning after December 15, 2016. The Company adopted this new guidance beginning with the annual period beginning January 1, 2017. No adjustments were required to be made to the financial statements as a result of the Company's adoption of this new guidance.
