Overview
GenMark was formed byOsmetech plc , orOsmetech , as aDelaware corporation inFebruary 2010 , and had no operations prior to its initial public offering, which was completed inJune 2010 . Immediately prior to the closing of the initial public offering, GenMark acquired all of the outstanding ordinary shares ofOsmetech in a reorganization under the applicable laws of theUnited Kingdom . Following the reorganization,Osmetech became a wholly-owned subsidiary controlled by GenMark, and the former shareholders ofOsmetech received shares of GenMark. Any historical discussion of GenMark relates toOsmetech and its consolidated subsidiaries prior to the reorganization. InSeptember 2012 , GenMark placedOsmetech into liquidation to simplify its corporate structure. The liquidation ofOsmetech was competed in the fourth quarter of 2013.
We are a molecular diagnostics company focused on developing and commercializing multiplex solutions designed to enhance patient care, improve key quality metrics, and reduce the total cost-of-care. We currently develop and commercialize high-value, simple to perform, clinically relevant multiplex molecular tests based on our proprietary eSensor electrochemical detection technology.
Since inception, we have incurred net losses from operations each year, and we expect to continue to incur losses for the foreseeable future. Our net losses for the six months endedJune 30, 2020 and 2019 were approximately$11.7 million and$25.4 million , respectively. As ofJune 30, 2020 , we had an accumulated deficit of$525.9 million . Our operations to date have been funded principally through sales of capital stock, borrowings, and cash from operations. Our Products and Technology We offer our ePlex sample-to-answer instrument andRespiratory Pathogen (RP) Panel ,Blood Culture Identification Gram-Positive (BCID-GP) Panel ,Blood Culture Identification Gram-Negative (BCID-GN) Panel , andBlood Culture Identification Fungal Pathogen (BCID-FP) Panel for sale inthe United States and internationally. In addition, in response to the COVID-19 outbreak, we received Emergency Use Authorization (EUA) from theU.S. Food and Drug Administration , or the FDA, inMarch 2020 for our ePlex SARS-CoV-2 test. We have also submitted an EUA to the FDA for our ePlexRespiratory Pathogen Panel 2 (RP2 ) duringJune 2020 , which is designed to provide results for SARS-CoV-2 in addition to the other respiratory viruses contained on our ePlexRP Panel . We are also developing our ePlexGastrointestinal Pathogen Panel for the detection of pathogens associated with 23 -------------------------------------------------------------------------------- Table of Contents gastrointestinal infections. We continue to actively evaluate the development of additional assay panels that we believe will meet important, unmet clinical needs, which our ePlex system is uniquely positioned to address. We offer four FDA-cleared diagnostic tests which run on our XT-8 instrument: ourRespiratory Viral Panel ; our Cystic Fibrosis Genotyping Test; our Warfarin Sensitivity Test; and our Thrombophilia Risk Test. We also offer a Hepatitis C (HCV) Genotyping Test and associated custom manufactured reagents, as well as a 2C19 Genotyping Test, each of which is available for use with our XT-8 instrument for research use only (RUO).
Revenue
Revenue from operations includes revenue from the sale of our products and other services. Product revenue comprises the sale of diagnostic tests and instruments. In addition to selling our instruments, we also place our instruments with customers through a reagent rental agreement, under which we retain title to the instrument and customers generally commit to purchasing minimum quantities of reagents and test cartridges over a period of one to five years. Under our reagent rental agreements, a portion of the price charged to customers from the sale of test cartridges is attributable to the usage fee for the instrument. Other revenue primarily consists of freight revenue and revenue from extended service agreements. Cost of Revenues Cost of revenues includes the cost of materials, direct labor, and manufacturing overhead costs used in the manufacture of our consumable tests. Cost of revenues also includes depreciation on revenue generating instruments that have been placed with our customers under a reagent rental agreement, cost of instruments sold to customers, amortization of licenses related to our products, and other costs such as warranty, royalty, and customer and product technical support. Any potential underutilized capacity may result in a high cost of revenues relative to revenue, if manufacturing volumes are not able to fully absorb operating costs. Our instruments are procured from contract manufacturers. We expect our cost of revenues to increase as we place additional instruments and manufacture and sell additional diagnostic panels; however, over time, we expect our cost per unit to decrease as production volume increases, manufacturing efficiencies are realized, improvements to procurement practices are made, product reliability increases, and other improvements decrease costs. Sales and Marketing Expenses Sales and marketing expenses include costs associated with our direct sales force, sales management, marketing, technical support, and business development activities. These expenses primarily consist of salaries, commissions, benefits, stock-based compensation, travel, advertising, promotions, product samples, and trade show expenses. Research and Development Expenses Research and development expenses primarily include costs associated with the development and expansion of our ePlex instrument's diagnostic test menu. These expenses also include certain clinical study expenses incurred in preparation for FDA clearance for these products, intellectual property prosecution and maintenance costs, and quality assurance expenses. The expenses primarily consist of salaries, benefits, stock-based compensation, outside design and consulting services, laboratory supplies, costs of consumables and materials used in product development, and clinical studies and facility costs. We expense all research and development expenses in the periods in which they are incurred. General and Administrative Expenses Our general and administrative expenses include costs associated with our executive, accounting and finance, compliance, information technology, legal, facilities, human resources, administrative, and investor relations activities. These expenses consist primarily of salaries, benefits, stock-based compensation, independent auditor costs, legal fees, consultant costs, insurance premiums, and public company expenses, such as stock transfer agent fees and listing fees for NASDAQ. Foreign Exchange Gains and Losses Transactions in currencies other than our functional currency, theU.S. Dollar, are translated at the prevailing rates on the dates of the applicable transaction. Foreign exchange gains and losses arise from differences in exchange rates during the period between the date a transaction denominated in a foreign currency is consummated and the date on which it is settled or translated. Interest Income and Interest Expense Interest income includes interest earned on our cash and cash equivalents and investments. Interest expense represents interest incurred on our loan payable and on other liabilities. Provision for Income Taxes We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. 24 -------------------------------------------------------------------------------- Table of Contents We assess the likelihood that we will be able to recover our deferred tax assets. We consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income, and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. If it is more likely than not that we will not recover our deferred tax assets, we will increase our provision for income taxes by recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable. Our income tax returns are based on calculations and assumptions that are subject to examination by the Internal Revenue Service and other tax authorities. In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While we believe we have appropriate support for the positions taken on our tax returns, we regularly assess the potential outcomes of examinations by tax authorities in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and adjust the income tax provision, income taxes payable, and deferred taxes in the period in which the facts that give rise to a revision become known.

Liquidity and Capital Resources
To date, we have funded our operations primarily from the sale of our common stock, borrowings, and cash from operations. We have incurred net losses from continuing operations each year and have not yet achieved profitability. As ofJune 30, 2020 , we had$138.3 million of working capital, including$132.8 million in cash, cash equivalents, and marketable securities. We believe our existing cash, cash equivalents and marketable securities as ofJune 30, 2020 will enable us to fund our operations for at least the next 12 months.
The following table summarizes, for the periods indicated, selected items in our unaudited condensed consolidated statements of cash flows:

The increase in cash provided by operating activities was primarily due to a decrease of$13.7 million in net loss and an increase of$3.2 million in non-cash adjustments. The increase in cash provided by operating activities was partially offset by a decrease of$855 thousand from changes in operating assets and liabilities. The changes in operating assets and liabilities was primarily a result of increases in accounts payable, accrued liabilities, and other liabilities, partially offset by increases in accounts receivable and inventory. 27 -------------------------------------------------------------------------------- Cash used in investing activities Net cash used in investing activities increased by$33.9 million for the six months endedJune 30, 2020 , compared to the same period of the prior year, primarily due to increases of$32.7 million in purchases of marketable securities and$1.2 million in purchases of property and equipment. Cash provided by financing activities Net cash provided by financing activities increased by$69.4 million for the six months endedJune 30, 2020 , compared to the same period of the prior year, primarily due to increases of$77.6 million in net proceeds from the issuance of common stock and$3.1 million from stock option exercises. The increase in cash provided by financing activities was partially offset by$11.4 million from net borrowings under our loan and security agreement. We have prepared cash flow forecasts which indicate, based on our current cash resources available, that we will have sufficient resources to fund our business for at least the next 12 months. Factors that could affect our capital requirements, in addition to those previously identified, include, but are not limited to:
• the level of revenues and the rate of our revenue growth;
• changes in demand from our customers;
• the level of cost of revenues and their impact to our gross margin;
• the level of expenses required to expand our commercial (sales and marketing) activities; • the level of research and development investment required to develop our diagnostic systems and test menu; • our need to acquire or license complementary technologies;
• the costs of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights;
• competing technological and market developments; and
• changes in regulatory policies or laws that affect our operations.
Loan and Security Agreement OnFebruary 1, 2019 , or the Effective Date, we entered into a Loan and Security Agreement, or the LSA, with Solar Capital Ltd. and certain other financial institutions, or, collectively, the Lenders. Pursuant to the LSA and certain subsequent amendments, the Lenders have provided us with$70 million in a series of term loans, of which$50 million was funded on the Effective Date and an additional$20 million was funded inDecember 2019 upon our achievement of a designated amount of product revenues on a trailing six-month basis. The term loans under the LSA accrue interest at a floating per annum rate in effect from time-to-time equal to (a) the greater of 2.51% or the one-monthIntercontinental Exchange Benchmark Administration, Ltd. rate then in effect as of the applicable payment date, plus (b) 5.90% per annum. We are only required to make interest payments on amounts borrowed pursuant to the term loans from the applicable funding date untilFebruary 28, 2022 , or the Interest Only Period. Following the Interest Only Period, monthly installments of principal and interest under the term loans will be due until the original principal amount and applicable interest is fully repaid byFebruary 1, 2023 . Pursuant to the terms of the LSA, the Lenders are granted a security interest in (a) all of our personal property, other than intellectual property (which is subject to a negative pledge), but including our rights to payment in respect of intellectual property, and (b) the stock of all of our subsidiaries; provided that if the pledge of 100% of the voting shares of our non-U.S. subsidiaries would result in adverse tax consequences, such pledge shall be limited to 65% of the voting stock and 100% of the non-voting stock of each of our non-U.S. subsidiaries. The LSA contains customary affirmative and negative covenants, including, without limitation, delivering reports and notices relating to our financial condition and certain regulatory events and intellectual property matters, as well as limiting the creation of liens, the incurrence of indebtedness, and the making of certain investments, payments and acquisitions, other than as specifically permitted by the LSA. The LSA also contains customary events of default (subject, in certain instances, to specified cure periods), including, but not limited to, the failure to make payments of interest or premium when due, the failure to comply with certain covenants and agreements specified in the LSA, and the occurrence of a material adverse change, certain regulatory events, or certain insolvency events. Upon the occurrence of an event of default, the Lenders may declare all outstanding principal and accrued but unpaid interest under the LSA immediately due and payable and may exercise the other rights and remedies as set forth in the LSA. Equity Distribution Agreement OnAugust 5, 2019 , we entered into an Equity Distribution Agreement, or the Distribution Agreement, withCanaccord Genuity LLC , or Canaccord, pursuant to which we may offer and sell, from time to time, shares of our common stock having an aggregate offering price of up to$35 million . Under the Distribution Agreement, Canaccord may sell shares by any method deemed to be an "at-the-market" offering as defined in Rule 415 under theU.S. Securities Act of 1933, as amended, or any other method permitted by law, including in privately negotiated transactions. We are not obligated to sell any shares under the Distribution Agreement. 28 -------------------------------------------------------------------------------- Canaccord is entitled to a commission of 3% of the aggregate gross proceeds from each sale of shares occurring pursuant to the Distribution Agreement. During the six months endedJune 30, 2020 , we sold 363,120 shares of common stock under the Equity Distribution Agreement at a weighted average price per share of$6.13 resulting in aggregate gross proceeds of$2.2 million . We incurred$67 thousand in commissions paid to Canaccord in connection with such sales. As ofJune 30, 2020 , the Company may issue up to an additional$19.7 million of its common stock under the Distribution Agreement.Biomedical Advanced Research and Development Authority (BARDA) Funding InMarch 2020 , we were awarded up to$749 thousand from theBiomedical Advanced Research and Development Authority (BARDA), part of theDepartment of Health andHuman Services Office of the Assistant Secretary for Preparedness and Response, to develop and pursue FDA Emergency Use Authorization (EUA) of a diagnostic panel that incorporates the new SARS-CoV-2 viral target into our existing ePlexRP Panel . InJune 2020 , we submitted our ePlexRP2 Panel to the FDA for EUA. Underwriting Agreement OnMay 6, 2020 , the Company entered into an Underwriting Agreement, or the Underwriting Agreement, withCowen and Company, LLC andWilliam Blair & Company, LLC acting as joint book-running managers and as representatives of the underwriters named therein, or collectively, the Underwriters, relating to the issuance and sale of 7,253,886 shares of common stock and an option, exerciseable by the Underwriters for 30 days, to purchase up to an additional 1,088,082 shares of common stock. The Company closed the Offering onMay 11, 2020 and sold 8,341,968 shares of common stock, including the full exercise of the Underwriters' option, at a public offering price of$9.65 per share before underwriting fees and discounts. The Company raised$75.4 million in net proceeds from the Offering, after deducting underwriters discounts and commissions and offering expenses. Letter of Credit The Company has provided an aggregate of$1.6 million in letters of credit to the landlords of certain of its leased facilities and maintains$42 thousand in required minimum account balances with the financial institutions issuing such letters of credit. As a result, the Company maintains$1.6 million of restricted cash in connection with these lease agreements as ofJune 30, 2020 . If we require additional capital, we cannot be certain that it will be available when needed or that our actual cash requirements will not be greater than anticipated. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we raise additional funds through collaborations and licensing arrangements, we may be required to relinquish significant rights to our technologies or products, or grant licenses on terms that are not favorable to us. Contractual Obligations As ofJune 30, 2020 , there were no material changes to our contractual obligations from those disclosed within the "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year endedDecember 31, 2019 . Critical Accounting Policies and Estimates Our discussion and analysis of our financial condition and results of operations are based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance withU.S. GAAP. The preparation of these financial statements requires us to make certain estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We evaluate our estimates on an ongoing basis, including those related to doubtful accounts, inventories, valuation of intangible assets and other long-term assets, income taxes, and stock-based compensation. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting policies and estimates are discussed in our Annual Report on Form 10-K for the fiscal year endedDecember 31, 2019 . There have been no material changes to our critical accounting policies and estimates during the six months endedJune 30, 2020 . Off-Balance Sheet Arrangements We have no off-balance sheet arrangements. The Company has provided$1.6 million in letters of credit to the landlords of certain of its leased facilities, which is recorded as restricted cash on our unaudited condensed consolidated balance sheets. 29
