NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Unaudited

NOTE 1. ORGANIZATION AND NATURE OF BUSINESS; BASIS OF PRESENTATION; PRINCIPLES OF CONSOLIDATION; SIGNIFICANT ACCOUNTING POLICIES

Accelerate Diagnostics, Inc. (“we” or “us” or “our” or “Accelerate” or the “Company”) is an in vitro diagnostics company dedicated to providing solutions that improve patient outcomes and lower healthcare costs through the rapid diagnosis of serious infections.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as filed with the SEC on March 2, 2021.

The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited financial statements as of that date but does not include all disclosures such as notes required by U.S. GAAP.

The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the entire year ending December 31, 2021, or any future period.

All amounts are rounded to the nearest thousand dollars unless otherwise indicated.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after elimination of intercompany transactions and balances.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to accounts receivable, inventory, property and equipment, accrued liabilities, warranty liabilities, tax valuation accounts, equity–based compensation, revenue and leases. Actual results could differ materially from those estimates.

Estimated Fair Value of Financial Instruments

The Company follows Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, which has defined fair value and requires the Company to establish a framework for measuring and disclosing fair value. The framework requires the valuation of assets and liabilities subject to fair value measurements using a three-tiered approach and fair value measurement to be classified and disclosed in one of the following three categories:

•Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

9

•Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;

•Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).

The carrying amounts of financial instruments such as cash and cash equivalents, trade accounts receivable, prepaid expenses, other current assets, accounts payable, accrued liabilities, and other current liabilities approximate the related fair values due to the short-term maturities of these instruments.

The estimated fair value of the Company’s convertible note represents a Level 2 measurement. See Note 10, Convertible Notes for further detail on the Company’s convertible notes.

The estimated fair value of the Company’s long-term debt represents a Level 3 measurement. The promissory notes issued under the Paycheck Protection Program (PPP) and other long-term debt is privately held with no public market. The carrying amount of these notes approximates fair value. See Note 9, Long-Term Debt for further detail on the Company’s long-term debt.

Cash and Cash Equivalents

All highly liquid investments with an original maturity of three months or less at time of purchase are considered to be cash equivalents. Cash and cash equivalents include overnight repurchase agreement accounts and other investments. As part of our cash management process, excess operating cash is invested in overnight repurchase agreements with our bank. Repurchase agreements and other investments classified as cash and cash equivalents are not deposits and are not insured by the U.S. Government, the FDIC or any other government agency and involve investment risk including possible loss of principal. We believe, however, that the market risk arising from holding these financial instruments is minimal.

Investments

The Company invests in various debt and equity securities which are primarily held in the custody of major financial institutions. Debt securities consist of certificates of deposit, U.S. government and agency securities, commercial paper, and corporate notes and bonds. Equity securities consist of mutual funds. The Company records these investments in the condensed consolidated balance sheet at fair value. Unrealized gains or losses for debt securities available-for-sale are included in accumulated other comprehensive income, a component of stockholders’ deficit. Unrealized gains or losses for equity securities are included in other income (expense), net. The Company considers all debt securities available-for-sale, including those with maturity dates beyond 12 months, as available to support current operational liquidity needs. The Company classifies its investments as current based on the nature of the investments and their availability for use in current operations.

We perform an assessment to determine whether there have been any events or economic circumstances to indicate that a debt security available-for-sale in an unrealized loss position has suffered impairment as a result of credit loss or other factors. A debt security is considered impaired if its fair value is less than its amortized cost basis at the reporting date.

If we intend to sell the debt security or if it is more-likely-than-not that we will be required to sell the debt security before the recovery of its amortized cost basis, the impairment is recognized and the unrealized loss is recorded as a direct write-down of the security's amortized cost basis with an offsetting entry to earnings. If we do not intend to sell the debt security or believe we will not be required to sell the debt security before the recovery of its amortized cost basis, the impairment is assessed to determine if a credit loss component exists. We use a discounted cash flow method to determine the credit loss component. In the event a credit loss exists, an allowance for credit losses is recorded in earnings for the credit loss component of the impairment while the remaining portion of the impairment attributable to factors other than credit loss is recognized, net of tax, in accumulated other comprehensive income. The amount of impairment recognized due to credit factors is limited to the excess of the amortized cost basis over the fair value of the security.

10

Inventory

Inventory is stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first out method. The Company estimates the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. The Company periodically analyzes its inventory levels to identify inventory that may expire prior to expected sale or has a cost basis in excess of its estimated realizable value and records a charge to expense for such inventory as appropriate.

Accounts Receivable

Accounts receivable consist of amounts due to the Company for sales to customers and are based on what we expect to collect in exchange for goods and services. Receivables are considered past due based on the contractual payment terms and are written off if reasonable collection efforts prove unsuccessful.

We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the condensed consolidated statements of operations. We assess collectibility by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when we identify specific customers with known disputes or collectibility issues. In determining the amount of the allowance for credit losses, we consider historical collectibility and make judgments about the creditworthiness of customers based on credit evaluations. Our customers typically have good credit quality. We also consider customer-specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. The allowance for credit losses at June 30, 2021 and December 31, 2020 was $0.2 million and $0.4 million, respectively.

The allowance for credit losses for the three and six months ended June 30, 2021 and 2020 is comprised of the following (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Beginning balance	$	209	$	110	$	445	$	—
Provisions	7		(12)		38		98
Write-offs	(3)		43		(270)		43
Recoveries	—		—		—		—
Ending balance	$	213	$	141	$	213	$	141

The write-offs recorded during the six months ended June 30, 2021 were in connection with a one time restructuring activity of the Company's Europe, Middle East and Africa (“EMEA”) business. These credit losses were incurred as part of the Company terminating agreements with select distributors in geographies it exited and did not pursue collection of these accounts receivables. The credit losses and bad debt expense was accrued as of December 31, 2020.

Property and Equipment

Property and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred and expenditures for major improvements are capitalized. Gains and losses from retirement or replacement are included in costs and expenses. Depreciation of property and equipment is computed using the straight-line method over the estimated useful life of the assets, ranging from one to seven years. Leasehold improvements are depreciated over the remaining life of the lease or the life of the asset, whichever is less.

Instruments Classified as Property and Equipment

Property and equipment includes Accelerate Pheno systems (also referred to as instruments) used for sales demonstrations, instruments under rental agreements and instruments used for research and development. Depreciation expense for instruments used for sales demonstrations is recorded as a component of sales, general and administrative expense. Depreciation expense for instruments placed at customer sites pursuant to reagent

11

rental agreements is recorded as a component of cost of sales. Depreciation expense for instruments used in our laboratory and research is recorded as a component of research and development expense. The Company retains title to these instruments and depreciates them over five years. Losses from the retirement of returned instruments are included in costs and expenses.

The Company evaluates the recoverability of the carrying amount of its instruments whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, and this evaluation is performed at least annually. This evaluation is based on our estimate of future cash flows and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of instruments. No impairment charges have been recorded as of June 30, 2021 and December 31, 2020.

Long-lived Assets

Long-lived assets and certain identifiable intangibles to be held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company continuously evaluates the recoverability of its long-lived assets based on estimated future cash flows from and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of the long-lived asset.

Warranty Reserve

Instruments are typically sold with a one year limited warranty, while kits and accessories are typically sold with a sixty days limited warranty. Accordingly, a provision for the estimated cost of the limited warranty repair is recorded at the time revenue is recognized. Our estimated warranty provision is based on our estimate of future repair events and the related estimated cost of repairs. The Company periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary. The expense incurred for these provisions is included in cost of sales on the condensed consolidated statements of operations and comprehensive loss.

Warranty reserve activity for the three and six months ended June 30, 2021 and 2020 is as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Beginning balance	$	184	$	342	$	232	$	403
Provisions	12		—		(10)		—
Warranty cost incurred	(27)		(37)		(53)		(98)
Ending balance	$	169	$	305	$	169	$	305

Paycheck Protection Program (PPP) Loan

The PPP was established by the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act, through a significant expansion of the Small Business Administration (“SBA”) 7(a) loan program. On April 14, 2020, the Company entered into a promissory note (the “PPP Note”) evidencing an unsecured loan in the amount of $4.8 million.

The Company elected to account for the PPP Note in accordance with ASC 470, Debt, with interest accrued in accordance with the interest method under ASC 835-30, Imputation of Interest. The Company recognized the entire PPP Note amount as a liability on the balance sheet, with interest accrued and expensed over the term of the loan. The Company did not impute additional interest at a market rate because transactions where interest rates are prescribed by governmental agencies are excluded from the scope of ASC 835-30.

12

The PPP Note remains a liability until either of the following criteria are met:

•the Company is legally released from being the primary obligor under the liability (i.e. the PPP Note is forgiven); or

•the Company pays the lender and is relieved of its obligation for the liability

In January 2021, the Company submitted its application for forgiveness to the loan provider, and on July 15, 2021, the SBA informed the Company of its full forgiveness in the amount of $4.8 million. See Note 9, Long-Term Debt and Note 19, Subsequent Events for further detail regarding the PPP Note.

Convertible Notes

The Company accounts for convertible debt instruments that may be settled in cash or equity upon conversion, which includes the 2.50% Senior Convertible Notes due 2023 (the “Notes”), by separating the liability and equity components of the instruments in a manner that reflects our nonconvertible debt borrowing rate. The Company determined the carrying amount of the liability component of the Notes by using estimates and assumptions that market participants would use in pricing a debt instrument. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component, and the associated non-cash interest expense.

The equity component is treated as a discount on the liability component of the Notes, which is amortized over the term of the Notes using the effective interest rate method. Debt issuance costs related to the Notes are allocated to the liability and equity components of the Notes based on their relative values. Debt issuance costs allocated to the liability component are amortized over the life of the Notes as additional non-cash interest expense. Transaction costs allocated to equity are netted with the equity component of the convertible debt instrument in stockholders’ deficit.

Revenue Recognition

The Company recognizes revenue when control of the promised good or service is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Sales taxes are excluded from revenues.

The Company determines revenue recognition through the following steps:

•Identification of the contract with a customer

•Identification of the performance obligations in the contract

•Determination of the transaction price

•Allocation of the transaction price to the performance obligations

•Recognition of revenue as we satisfy a performance obligation

Product revenue is derived from the sale or rental of our instruments and sales of related consumable products. When an instrument is sold, revenue is generally recognized upon installation of the unit consistent with contract terms, which do not include a right of return. When a consumable product is sold, revenue is generally recognized upon shipment. Invoices are generally issued when revenue is recognized and the term between invoicing and when payment is due is not typically significant.

Service revenue is derived from the sale of extended service agreements which are generally non-cancellable. This revenue is recognized on a straight-line basis over the contract term beginning on the effective date of the contract because the Company is standing ready to provide services. Invoices are generally issued annually and coincide with the beginning of individual service terms.

13

Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine relative standalone selling prices based on the price charged to customers for each individual performance obligation.

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The Company has determined these costs would have an amortization period of less than one year and has elected to recognize them as an expense when incurred. Contract asset opening and closing balances were immaterial for the three and six months ended June 30, 2021.

Cost of Sales

Cost of sales includes cost of materials, direct labor, equity-based compensation, facility and other manufacturing overhead costs for consumable tests and instruments sold to customers. Cost of sales for instruments also includes depreciation on revenue generating instruments that have been placed with our customers under a reagent rental agreement. Cost of sales includes repair and maintenance cost for instruments covered by a service agreement or instruments covered by a reagent rental agreement. Cost of sales also includes warranty related expenses.

Shipping and Handling

Shipping and handling costs billed to customers are included as a component of revenue. The corresponding expense incurred with third party carriers is included as a component of sales, general and administrative costs on the condensed consolidated statements of operations and comprehensive loss.

Leases

The Company accounts for commercial leases in accordance with ASC 842, Leases. We determine if an arrangement is or contains a lease and the type of lease at inception. The Company classifies commercial leases as finance leases (lessee) or sales-type leases (lessor) when there is either a transfer of ownership of the underlying asset by the end of the lease term, the lease contains an option to purchase the asset that we are reasonably certain will be exercised, the lease term is for the major part of the remaining economic life of the asset, the present value of the lease payments and any residual value guarantee equals or substantially exceeds all the fair value of the asset, or the asset is of such a specialized nature that it will have no alternative use to the lessor at the end of the lease term. Payments contingent on future events (i.e. based on usage) are considered variable and excluded from lease payments for the purposes of classification and initial measurement. Several of our leases include options to renew or extend the term upon mutual agreement of the parties and others include one-year extensions exercisable by the lessee. None of our leases contain residual value guarantees, restrictions, or covenants.

To determine whether a contract contains a lease, the Company uses its judgment in assessing whether the lessor retains a material amount of economic benefit from an underlying asset, whether explicitly or implicitly identified, which party holds control over the direction and use of the asset, and whether any substantive substitution rights over the asset exist.

Lessee

Operating leases are included in right-of-use (“ROU”) assets and operating lease liabilities within our consolidated balance sheets. These assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and their related liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Typically, we use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments. We use the implicit rate when readily determinable. ROU assets are net of lease payments made and exclude lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term, which may include options to extend or terminate the lease when it is reasonably certain that we will exercise the option. As of June 30, 2021 and December 31, 2020, the Company was not a party to finance lease arrangements.

14

Our operating leases consist primarily of leased office, factory, and laboratory space in the U.S. and office space in Europe, have between two and six-year terms, and typically contain penalizing, early-termination provisions.

Lessor

The Company leases instruments to customers under “reagent rental” agreements, whereby the customer agrees to purchase consumable products over a stated term, typically five years or less, for a volume-based price that includes an embedded rental for the instruments. When collectibility is probable, that amount is recognized as income at lease commencement for sales-type leases and as product is shipped, typically in a straight–line pattern, over the term for operating leases, which typically include a termination without cause or penalty provision given a short notice period.

Consideration is allocated between lease and non-lease components based on stand-alone selling price in accordance with ASC 606, Revenue from Contracts with Customers.

Net investment in sales-type leases are included within our condensed consolidated balance sheets as a component of other current assets and other non-current assets, which include the present value of lease payments not yet received and the present value of the residual asset, which are determined using the information available at commencement, including the lease term, estimated useful life, rate implicit in the lease, and expected fair value of the instrument.

Nonqualified Cash Deferral Plan

The Company's Cash Deferral Plan (the “Deferral Plan”), provides certain key employees, with an opportunity to defer the receipt of such participant's base salary. The Deferral Plan is intended to be a nonqualified deferred compensation plan that complies with the provisions of Section 409A of the Internal Revenue Code. All of the investments held in the Deferral Plan are equity securities consisting of mutual funds and recorded at fair value with changes in the investments' fair value recognized as earnings in the period they occur. The corresponding liability for the Deferral Plan is included in other non-current liabilities in the condensed consolidated balance sheet.

Equity-Based Compensation

The Company may award stock options, restricted stock units (“RSUs”), performance-based awards, and other equity-based instruments to its employees, directors and consultants. Compensation cost related to equity-based instruments is based on the fair value of the instrument on the grant date, and is recognized over the requisite service period on a straight-line basis over the vesting period for each tranche (an accelerated attribution method) except for performance-based awards. Performance-based awards vest based on the achievement of performance targets. Compensation costs associated with performance-based awards are recognized over the requisite service period based on probability of achievement. Performance-based awards require management to make assumptions regarding the likelihood of achieving performance targets.

The Company estimates the fair value of service based and performance based stock option awards, including modifications of stock option awards, using the Black-Scholes option pricing model. This model derives the fair value of stock options based on certain assumptions related to expected stock price volatility, expected option life, risk-free interest rate and dividend yield.

•Volatility: The expected volatility is based on the historical volatility of the Company's stock price over the most recent period commensurate with the expected term of the stock option award.

•Expected term: The estimated expected term for employee awards is based on the calculation published by the SEC in SAB110 for use when there is not a sufficient history of employee exercise patterns. For consultant awards, the estimated expected term is the same as the life of the award.

•Risk-free interest rate: The risk-free interest rate is based on published U.S. Treasury rates for a term commensurate with the expected term.

•Dividend yield: The dividend yield is estimated as zero as the Company has not paid dividends in the past and does not have any plans to pay any dividends in the foreseeable future.

15

The Company records the fair value of RSUs or stock grants based on published closing market price on the day before the grant date. The Company accounts for forfeitures as they occur rather than on an estimated basis.

Deferred Tax

Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying balance sheets. The change in deferred tax assets and liabilities for the period represents the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws in deferred tax assets and liabilities are reflected as an adjustment to the tax provision or benefit in the period of enactment.

The Company follows the provisions of ASC 740, Income Taxes, to account for any uncertainty in income taxes with respect to the accounting for all tax positions taken (or expected to be taken) on any income tax return. This guidance applies to all open tax periods in all tax jurisdictions in which the Company is required to file an income tax return. Under U.S. GAAP, in order to recognize an uncertain tax benefit, the taxpayer must be more likely than not certain of sustaining the position, and the measurement of the benefit is calculated as the largest amount that is more likely than not to be realized upon resolution of the position. Interest and penalties, if any, would be recorded within tax expense.

Foreign Currency Translation and Foreign Currency Transactions

Adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars are included in the foreign currency translation adjustment, a component of accumulated other comprehensive income loss.

The Company has assets and liabilities, including receivables and payables, which are denominated in currencies other than their functional currency. These balance sheet items are subject to re-measurement, the impact of which is recorded in foreign currency exchange gain and loss, within the condensed consolidated statement of operations and comprehensive loss.

Loss Per Share

Basic loss per share includes no dilution and is computed by dividing loss available to common stockholders by the weighted average number of common shares outstanding for the period. Potentially dilutive common shares consist of shares issuable from stock options and unvested RSUs. Potentially dilutive common shares would also include common shares that would be outstanding if the Notes at the balance sheet date were converted and shares issuable in connection with a securities purchase agreement. Diluted earnings are not presented when the effect of adding such additional common shares is antidilutive.

Comprehensive Loss

In addition to net loss, comprehensive loss includes all changes in equity during a period, except those resulting from investments by and distributions to owners. The Company holds investments classified as debt securities available-for-sale and records the change in fair market value as a component of comprehensive loss. The Company also has adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars which is included as a component of comprehensive loss.

NOTE 2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Standards that were recently adopted

In January 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the FASB Emerging Issues Task Force). ASU 2020-01 clarifies the interaction of the accounting for equity securities under Topic 321, the accounting for the equity method investments in Topic 323 and the accounting for certain forward contracts and purchased options in Topic 815. The Company adopted ASU 2020-01 on January 1, 2021, which had no impact to our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740); Simplifying the Accounting for Income Taxes. ASU 2019-12 reduces complexity in the accounting standard. The Company adopted ASU 2019-12 on January 1, 2021, which had no impact to our consolidated financial statements. The Company maintains a full valuation allowance against its net deferred tax assets. The valuation allowance is based on management’s assessment that it is more likely than not that the Company will not have taxable income in the foreseeable future.

Standards not yet adopted

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 reduces the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. In addressing the complexity, this ASU amends the guidance on convertible instruments and the guidance on the derivatives scope exception for contracts in an entity’s own equity. This ASU will reduce the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP standards. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. This ASU is effective for us on January 1, 2022, with early adoption permitted. We are currently assessing the impact this will have on our consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2021-04 will codify the final consensus reached by the Emerging Issues Task Force (EITF) on how an issuer should account for modifications made to equity-classified written call options (hereafter referred to as a warrant to purchase the issuer’s common stock). The guidance in the ASU requires the issuer to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange of the original warrant for a new warrant. This guidance applies whether the modification is structured as an amendment to the terms and conditions of the warrant or as termination of the original warrant and issuance of a new warrant. This ASU is effective for us on January 1, 2022, with early adoption permitted. We are currently assessing the impact this will have on our consolidated financial statements, and believe it will not have an impact on the Company's consolidated financial statements at January 1, 2022.

NOTE 3. CONCENTRATION OF CREDIT RISK

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, short-term investments and accounts receivable.

The Company has financial institutions for banking operations that hold 10% or more of the Company’s cash and cash equivalents. As of June 30, 2021, three of the Company's financial institutions held 61%, 16% and 13% of the Company’s cash and cash equivalents, respectively. As of December 31, 2020, three of the Company's financial institutions held 53% and 14% and 16% of the Company’s cash and cash equivalents, respectively.

17

The Company grants credit to domestic and international customers. Exposure to losses on accounts receivable is principally dependent on each client's financial position. None of the Company's customers accounted for 10% or more of the net accounts receivable balance as of June 30, 2021 and December 31, 2020.

Customers who represented 10% or more of the Company’s total revenue for the three and six months ended June 30, 2021 and 2020 were as follows:

	Three Months Ended June 30,			Six Months Ended June 30,
	2021	2020		2021	2020
Company A	*	10	%	*	*

* Less than 10% for the period indicated

Highly liquid investments with an original maturity of three months or less at time of purchase are included in cash and cash equivalents on the condensed consolidated balance sheet.

Level 1 assets are priced using quoted prices in active markets for identical assets which include money market funds, U.S. Treasury securities and mutual funds as these specific assets are liquid.

Level 2 available-for-sale securities are priced using quoted market prices for similar instruments or nonbinding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets and liabilities. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs.

In 2018, the Company issued the Notes, for total proceeds of $171.5 million, as described in Note 10, Convertible Notes. At June 30, 2021 and December 31, 2020, the fair value of the Notes were $112.7 million and $98.7 million, respectively. The fair value of the Notes is highly correlated to the Company’s stock price and as a result, significant changes to the Company’s stock price will have a significant impact on the calculated fair value. The fair value of the Notes are classified as Level 2 within the fair value hierarchy. See Note 10, Convertible Notes for further detail on the Company’s convertible notes.

The Company's PPP Note along with its other long-term notes, cumulatively $5.3 million, approximate their fair value. The estimated fair value of the Company’s long-term debt represents a Level 3 measurement. See Note 9, Long-Term Debt for further detail on the Company's long-term debt.

NOTE 8. DEFERRED REVENUE AND REMAINING PERFORMANCE OBLIGATIONS

Deferred revenue consists of amounts received for products or services not yet delivered or earned. If we anticipate revenue will not be earned within the following twelve months, the amount is reported as other non-current liabilities. A summary of the balances as of June 30, 2021 and December 31, 2020 follows (in thousands):

	June 30,		December 31,
	2021		2020
Products and services not yet delivered	$	282	$	376

We recognized $0.2 million and $0.3 million of revenues that were included in the beginning contract liabilities balances during the three and six months ended June 30, 2021, respectively, and $0.1 million and $0.2 million of revenues that were included in the beginning contract liabilities balances during the three and six months ended June 30, 2020, respectively. No material amount of revenue recognized during the period was from performance obligations satisfied in prior periods.

Transaction Price Allocated to Remaining Performance Obligations

As of June 30, 2021, $10.9 million of revenue is expected to be recognized from remaining performance obligations. This balance primarily relates to product shipments for reagents sold to customers under sales-type lease agreements. These agreements have between two and four year terms and revenue is recognized as product is shipped, typically on a straight-line basis. The remaining balance relates to executed service contracts that begin as warranty periods expire. These service contracts typically provide for four-year terms and revenue is recognized on a straight-line basis.

The Company elects not to disclose the value of unsatisfied performance obligations for (i) contracts with an expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

NOTE 9. LONG-TERM DEBT

Other notes payable

The Company entered into three loan agreements with two capital asset financing companies. Loan proceeds were $0.8 million, with interest rates ranging from 9.8% to 12.4% and maturities ranging from January 1, 2022 to September 2022. As of June 30, 2021, the current portion of long-term debt was $0.3 million and long-term debt was $0.1 million.

PPP Loan

On April 14, 2020, the Company entered into the PPP Note evidencing an unsecured loan in the amount of $4.8 million made to the Company under the PPP. The PPP was established under the CARES Act and is administered by the SBA.

On September 3, 2020 the Company's loan provider amended the PPP Note per the Paycheck Protection Program Flexibility Act (“PPP Flexibility Act”), which was enacted after the PPP Note was approved and funded. The PPP Flexibility Act amended the CARES Act to require that all PPP Note's made prior to June 5, 2020 be extended to a 5-year term. In accordance with this amendment the PPP Notes' original maturity date of April 14, 2022 was amended to April 14, 2025. The original terms of the loan required 18 monthly payments of principal and interest in the amount of $0.3 million starting November 14, 2020. The amended terms required 45 monthly payments of principal and interest in the amount of $0.1 million starting August 14, 2021. The PPP Note's interest rate was unchanged and bears an interest at a rate of 1% per annum.

The PPP Note could be prepaid by the Company at any time prior to maturity with no prepayment penalties. The proceeds from the PPP Note could only be used for payroll costs (including benefits), interest on mortgage obligations, rent, utilities and interest on certain other debt obligations.

The PPP Note contains customary events of default relating to, among other things, payment defaults, making materially false and misleading representations to the lender or breaching the terms of the PPP Note documents. The occurrence of an event of default could result in an increase in the interest rate to 18% per annum and provides the lender with customary remedies, including the right to require immediate payment of all amounts owed under the PPP Note.

Pursuant to the terms of the CARES Act and the PPP, the Company may apply to the Lender for forgiveness for the amount due on the Loan. The amount eligible for forgiveness is based on the amount of Loan proceeds used by the Company (during the 24-week period after the Lender makes the first disbursement of Loan proceeds) for the payment of certain covered costs, including payroll costs (including benefits), rent and utilities, subject to certain limitations and reductions in accordance with the CARES Act and the PPP.

During January 2021, the Company submitted its application for forgiveness to the Lender. On July 15, 2021, the SBA informed the Company of its full forgiveness for the entire Loan amount plus accrued interest, which was $4.8 million as of June 30, 2021. The SBA’s determination of loan forgiveness does not preclude further investigation by the SBA according to its rules and regulations. See Note 19, Subsequent Events for further detail on the status of the Company’s PPP Loan.

NOTE 10. CONVERTIBLE NOTES

On March 27, 2018, the Company issued $150.0 million aggregate principal amount of 2.50% Senior Convertible Notes due 2023. In connection with the offering of the Notes, the Company granted the initial purchasers of the Notes a 13-day option to purchase up to an additional $22.5 million aggregate principal amount of the Notes on the same terms and conditions. On April 4, 2018, the option was partially exercised, which resulted in $21.5 million of additional proceeds, for total proceeds of $171.5 million. The Notes are the Company's senior unsecured obligations and mature on March 15, 2023 (the “Maturity Date”), unless earlier repurchased or converted into shares of common stock under certain circumstances described below. Upon conversion of the Notes, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock, at the Company’s election. The initial conversion rate of the Notes is 32.3428 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $30.92 per share of common stock, subject to adjustment. The Company pays interest on the Notes semi-annually in arrears on March 15 and September 15 of each year.

23

The $171.5 million of proceeds received from the issuance of the Notes were allocated between long-term debt (the “liability component”) of $116.6 million and contributed capital (the “equity component”) of $54.9 million. The fair value of the liability component was measured using rates determined for similar debt instruments without a conversion feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the aggregate face value of the Notes. The liability component will be accreted up to the face value of the Notes of $171.5 million, which will result in additional non-cash interest expense being recognized through the Maturity Date. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.

The Company incurred approximately $5.0 million of issuance costs related to the issuance of the Notes, of which $3.4 million and $1.6 million were recorded to long-term debt and contributed capital, respectively. The $3.4 million of issuance costs recorded as long-term debt on the condensed consolidated balance sheet are being amortized over the five-year contractual term of the Notes using the effective interest method. The effective interest rate on the Notes, including accretion of the Notes to par and debt issuance cost amortization, is 11.52%.

The Notes include customary terms and covenants, including certain events of default upon which the Notes may be due and payable immediately. Holders have the option to convert the Notes in multiples of $1,000 principal amount at any time prior to December 15, 2022, but only in the following circumstances:

•if the Company’s stock price exceeds 130% of the conversion price for 20 of the last 30 trading days of any calendar quarter after June 30, 2018;

•during the 5 business day period after any 5 consecutive trading day period in which the Notes’ trading price is less than 98% of the product of the common stock price times the conversion rate; or

•the occurrence of certain corporate events, such as a change of control, merger or liquidation.

At any time on or after December 15, 2022, a holder may convert its Notes in multiples of $1,000 principal amount. Holders of the Notes who convert their Notes in connection with a make-whole fundamental change (as defined in the Indenture pursuant to which the Notes were issued) are, under certain circumstances, entitled to an increase in the conversion rate. In addition, in the event of a fundamental change or event of default prior to the Maturity Date, holders will, subject to certain conditions, have the right, at their option, to require the Company to repurchase for cash all or part of the Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest up to, but excluding, the repurchase date.

The Notes at June 30, 2021 and December 31, 2020 consisted of the following (in thousands):

	June 30,		December 31,
	2021		2020
Outstanding principal	$	171,500	$	171,500
Unamortized debt discount	(22,800)		(28,524)
Unamortized debt issuance	(1,410)		(1,765)
Net carrying amount of the liability component	$	147,290	$	141,211

Interest expense for the three and six months ended June 30, 2021 and 2020 were as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Contractual coupon interest	$	1,072	$	1,072	$	2,144	$	2,144
Amortization of the debt discount	2,903		2,591		5,724		5,109
Amortization of debt issuance costs	180		160		354		316
Total interest expense on convertible notes	$	4,155	$	3,823	$	8,222	$	7,569

As of June 30, 2021 and December 31, 2020, no Notes were convertible pursuant to their terms.

24

In connection with the Notes issuance, the Company entered into a prepaid forward stock repurchase transaction (“Prepaid Forward”) with a financial institution (“Forward Counterparty”). Pursuant to the Prepaid Forward, the Company used approximately $45.1 million of the net proceeds from its issuance of the Notes to fund the Prepaid Forward. The aggregate number of shares of the Company’s common stock underlying the Prepaid Forward was approximately 1,858,500. The expiration date for the Prepaid Forward is March 15, 2023, although it may be settled earlier in whole or in part. Upon settlement of the Prepaid Forward, at expiration or upon any early settlement, the Forward Counterparty will deliver to the Company the number of shares of common stock underlying the Prepaid Forward or the portion thereof being settled early. The shares purchased under the Prepaid Forward are treated as treasury stock and not outstanding for purposes of the calculation of basic and diluted earnings per share, but will remain outstanding for corporate law purposes, including for purposes of any future stockholders’ votes, until the Forward Counterparty delivers the shares underlying the Prepaid Forward to the Company. The Company’s Prepaid Forward hedge transaction exposes the Company to credit risk to the extent that its counterparty may be unable to meet the terms of the transaction. The Company mitigates this risk by limiting its counterparty to a major financial institution.

NOTE 11. EARNINGS PER SHARE

Basic net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period. Basic and diluted net loss per share are the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive due to the Company’s losses.

The following potentially issuable common shares were not included in the computation of diluted net loss per share because they would have an anti-dilutive effect for each of the three and six months ended June 30, 2021 and 2020 (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2021	2020	2021	2020
Shares issuable upon the release of restricted stock units	2,444	704	2,444	704
Shares issuable upon exercise of stock options	7,941	9,773	7,941	9,773
	10,385	10,477	10,385	10,477

Potentially dilutive common shares would also include common shares that would be outstanding if Notes convertible at the balance sheet date were converted. As discussed in Note 10, Convertible Notes, the Company issued $171.5 million of Notes due 2023. Upon conversion of the Notes, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock, at the Company’s election. The initial conversion rate of the Notes is 32.3428 shares of common stock per $1,000 principal amount of the Notes. As of June 30, 2021, no Notes were convertible pursuant to their terms. The number of shares issuable upon conversion of the Notes is 5.5 million shares.

In connection with the Notes, the Company entered into a prepaid forward stock repurchase transaction. The aggregate number of shares of the Company’s common stock underlying the Prepaid Forward was approximately 1,858,500. The shares purchased under the Prepaid Forward are treated as treasury stock and not outstanding for purposes of the calculation of basic and diluted earnings per share, but will remain outstanding for corporate law purposes, including for purposes of any future stockholders’ votes, until the Forward Counterparty delivers the shares underlying the Prepaid Forward to the Company.

As discussed in Note 17, Stockholders’ Equity, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain Purchasers (as defined in Note 17, Stockholders’ Equity) for the issuance and sale by the Company of an aggregate of 4,166,663 shares of the Company’s common stock. The agreement contemplates that the closing of the purchase and sale of the shares will occur in three approximately equal tranches on the dates as specified in the agreement or such other dates as the parties may agree, with the first and second tranches having closed on February 19, 2021, and April 9, 2021, respectively. Shares from the third tranche were not included in the computation of diluted net loss per share because they would have an anti-dilutive effect due to net losses.

As of June 30, 2021, unrecognized equity-based compensation expense related to unvested stock options and unvested RSUs was $9.4 million and $19.2 million, respectively. This is expected to be recognized over the years 2021 through 2026.

Included in the above-noted stock options outstanding and stock compensation expense are performance-based stock options which vest only upon the achievement of certain targets. Performance-based stock options are generally granted at-the-money, contingently vest over a period of 1 to 2 years, depending on the nature of the performance goal, and have contractual lives of 10 years. These options were valued in the same manner as the time-based options, with the assumption that performance goals will be achieved. The inputs for expected volatility, expected dividends, and risk-free rate used in estimating those options’ fair value are the same as the time-based options issued under the Company's 2012 Omnibus Equity Incentive Plan. The expected term for performance-based stock options is 5 to 7 years. However, the Company only recognizes stock compensation expense to the extent that the targets are determined to be probable of being achieved, which triggers the vesting of the performance options.

In 2020, the Company granted 105,000 performance-based stock options. 45,000 performance-based stock options vested in prior periods due to the performance obligations being achieved. During the six months ended June 30, 2021, another 45,000 performance-based stock options vested due to the performance obligations being achieved. None of these options have been forfeited as of June 30, 2021.

27

The table below summarizes share-based compensation cost in connection with performance-based stock options for the six months ended June 30, 2021 and 2020 (in thousands):

	Six Months Ended June 30,
	2021		2020
Performance-based stock option expense	$	230	$	—

Included in the above-noted RSU and performance-based award outstanding amounts are performance-based RSUs which vest only upon the achievement of certain targets. Performance-based RSUs contingently vest over a period of 1 to 3 years, depending on the nature of the performance goal, and have contractual lives of 10 years. These units were valued in the same manner as other RSUs, based on the published closing market price on the day before the grant date. However, the Company only recognizes stock compensation expense to the extent that the targets are determined to be probable of being achieved, which triggers the vesting of the performance options.

In 2020, the Company granted 364,338 performance-based RSUs. 81,000 performance-based RSUs were released in prior periods due to the performance obligations being achieved. 33,364 of these performance-based RSUs were forfeited due to the employees separating from the Company, of which 9,369 were forfeited during the six months ended June 30, 2021. During the six months ended June 30, 2021, 84,000 of these performance-based RSUs were released due to the performance obligations being achieved. At June 30, 2021 165,974 of these performance-based RSUs were outstanding. None of these performance-based RSUs have been forfeited due to performance obligations not being achieved.

In 2021, the Company granted 233,472 performance-based RSUs. During the six months ended June 30, 2021, 3,255 of these performance-based RSUs were forfeited due to the employees separating from the Company. None of these performance-based RSU's have been released. At June 30, 2021 230,217 of these performance-based RSUs were outstanding. None of these performance-based RSUs have been forfeited due to performance obligations not being achieved.

Performance-based RSU expense	$	818	$	—

NOTE 13. INCOME TAXES

For the six months ended June 30, 2021, the Company did not carry an income tax provision amount as the Company does not recognize tax benefits from current year tax losses in the U.S. and other foreign jurisdictions. The Company’s tax expense for the six months ended June 30, 2021 differs from the tax expense computed by applying the U.S. statutory tax rate to its year-to-date pre-tax loss of $45.9 million, as no tax benefits were recorded for tax losses generated in the U.S. and other foreign jurisdictions due to the valuation allowance. At June 30, 2021, the Company had deferred tax assets primarily related to U.S. federal and state tax loss carryforwards and a deferred tax liability related to amortization of the Notes. The Company provided a valuation allowance against its net deferred tax assets as future realization of such assets is not more likely than not to occur.

The Company accounts for uncertain tax positions pursuant to the recognition and measurement criteria under ASC 740, Income Taxes. For the three and six months ended June 30, 2021, we did not note any significant changes to our uncertain tax positions. We do not anticipate significant changes to uncertain tax positions within the next 12 months.

In December 2019, the FASB issued ASU No. 2019-12 Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. See Note 2, Recently Issued Accounting Pronouncements for additional information.

28

In the first quarter of 2021, the Company was informed by the IRS that they would begin an examination of the Company’s 2018 tax year. Due to the early stage of the examination, management is unable to determine the impact the examination will have on the Company's tax position.

NOTE 17. STOCKHOLDERS’ EQUITY

Equity Sales Agreement

On May 28, 2021, the Company entered into an Equity Sales Agreement (the “Sales Agreement”) with William Blair & Company, L.L.C. (“William Blair”) pursuant to which it may sell shares of the Company’s common stock having an aggregate offering price of up to $50 million, from time to time, through an “at-the-market” equity offering program under which William Blair will act as sales agent. Subject to the terms and conditions of the Sales Agreement, William Blair may sell shares by any method deemed to be an “at-the-market” offering as defined in Rule 415 under the U.S. Securities Act of 1933, as amended (the “Securities Act"). The Company is not obligated to sell any shares under the Sales Agreement. William Blair is entitled to a commission of 3% of the aggregate gross proceeds from each sale of shares occurring pursuant to the Sales Agreement. During the three months ended June 30, 2021, the Company sold 92,497 shares of common stock under the Sales Agreement at a price per share of $8.80 resulting in aggregate gross proceeds of $0.8 million, which was recorded to contributed capital.

Securities Purchase Agreement

On December 24, 2020, the Company entered into the Securities Purchase Agreement with Jack W. Schuler, John Patience, Matthew Strobeck, Mark C. Miller, Thomas D. Brown and Jack Phillips, or entities affiliated with such persons (collectively, the “Purchasers”), for the issuance and sale by the Company of an aggregate of 4,166,663 shares of the Company’s common stock (the “Shares”), to the Purchasers in an offering exempt from registration pursuant to Section 4(a)(2) of the Securities Act, and Rule 506 promulgated thereunder. Each of Jack W. Schuler, John Patience, Matthew Strobeck, Mark C. Miller, Thomas D. Brown and Jack Phillips is a member of the Company’s board of directors. Mr. Phillips also serves as the Company’s President and Chief Executive Officer. The entity affiliated with Jack W. Schuler that originally entered into the Securities Purchase Agreement subsequently entered into an assignment and assumption agreement whereby it assigned all of its rights and obligations as a Purchaser to three other entities that became Purchasers under the Securities Purchase Agreement. These three entities are related to Jack W. Schuler but are not affiliates of his.

Pursuant to the Securities Purchase Agreement, the Purchasers have agreed to purchase the Shares at a purchase price (determined in accordance with Nasdaq rules relating to the “market value” of the Company’s common stock) of $7.68 per share, which is equal to the consolidated closing bid price reported by Nasdaq immediately preceding the time the Company entered into the Securities Purchase Agreement for an aggregate purchase price of approximately $32 million. The Securities Purchase Agreement contemplates that the closing of the purchase and sale of the Shares will occur in three approximately equal tranches on the dates specified in the agreement or such other dates as the parties may agree, with the first and second tranches having closed on February 19, 2021 and April 9, 2021, respectively. Proceeds from the closings of the first and second tranches under the Securities Purchase Agreement were recorded to contributed capital of $10.7 million and $21.3 million for the three and six months ended June 30, 2021, respectively.

NOTE 18. RELATED PARTY TRANSACTIONS

Convertible notes

As discussed in Note 10, Convertible Notes, the Company issued Notes in March 2018. As of June 30, 2021 and December 31, 2020 an entity controlled by one member of the Company's board of directors held an aggregate of $42.0 million of the Notes.

Securities Purchase Agreement

On December 24, 2020, the Company entered into the Securities Purchase Agreement with the Purchasers for the issuance and sale by the Company of an aggregate of 4,166,663 Shares to the Purchasers for an aggregate purchase price of approximately $32 million. The Purchasers are comprised of certain directors and officers of the Company, or entities affiliated or related to such persons. See Note 17, Stockholders’ Equity, for further information.

31

NOTE 19. SUBSEQUENT EVENTS

The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Pursuant to the terms of the CARES Act and the PPP, the Company may apply to the Lender for forgiveness for the amount due on the Loan. The amount eligible for forgiveness is based on the amount of Loan proceeds used by the Company (during the 24-week period after the Lender makes the first disbursement of Loan proceeds) for the payment of certain covered costs, including payroll costs (including benefits), rent and utilities, subject to certain limitations and reductions in accordance with the CARES Act and the PPP.

During January 2021, the Company submitted its application for forgiveness to the Lender. On July 15, 2021, the SBA informed the Company of its full forgiveness for the entire Loan amount plus accrued interest, which was $4.8 million as of June 30, 2021. The SBA’s determination of loan forgiveness does not preclude further investigation by the SBA according to its rules and regulations.

With approval of the Company's application for forgiveness the Company will record income from the extinguishment as a gain recorded to other income (expense), net in the third quarter of 2021. See Note 9, Long-Term Debt for further detail on the Company’s PPP Loan.

Overview

Accelerate is an in vitro diagnostics company dedicated to providing solutions that improve patient outcomes and lower healthcare costs through the rapid diagnosis of serious infections. Microbiology laboratories need new tools to address what the U.S. Centers for Disease Control and Prevention (the “CDC”) calls one of the most serious healthcare threats of our time, antibiotic resistance. A significant contributing factor to the rise of resistance is the overuse and misuse of antibiotics, which is exacerbated by a lack of timely diagnostic results. The delay of identification and antibiotic susceptibility results is often due to the reliance by microbiology laboratories on traditional culture-based tests that often take two to three days to complete. Our technology platform is intended to address these challenges by delivering significantly faster testing of infectious pathogens in various patient sample types.

Our first system to address these challenges is the Accelerate Pheno® system. The Accelerate PhenoTest® BC Kit, which is the first test kit for the system, is indicated as an aid, in conjunction with other clinical and laboratory findings, in the diagnosis of bacteremia and fungemia, both life-threatening conditions with high morbidity and mortality risk. The device provides identification (“ID”) results followed by antibiotic susceptibility testing (“AST”) for certain pathogenic bacteria commonly associated with or causing bacteremia. This test kit utilizes genotypic technology to identify infectious pathogens and phenotypic technology to conduct AST, which determines whether live bacterial cells are resistant or susceptible to a particular antimicrobial. This information can be used by physicians to rapidly modify antibiotic therapy to lessen adverse events, improve clinical outcomes, and help preserve the useful life of antibiotics.

On June 30, 2015, we declared our conformity to the European In Vitro Diagnostic Directive 98/79/EC and applied a CE Mark to the Accelerate Pheno system and the Accelerate PhenoTest BC Kit for in vitro diagnostic use. On February 23, 2017, the U.S. Food and Drug Administration (“FDA”) granted our de novo classification request to market our Accelerate Pheno system and Accelerate PhenoTest BC Kit.

In 2017, we began selling the Accelerate Pheno system in hospitals in the United States, Europe, and the Middle East. Consistent with our “razor” / “razor-blade” business model, revenues to date have principally been generated from the sale or leasing of the instruments and the sale of single use consumable test kits.

In 2019 and 2020, based upon our initial experience selling and implementing the Accelerate Pheno system, we implemented initiatives to improve and refine our commercial execution and to re-engineer our product implementation processes. Improving our commercial and implementation capabilities remains an emphasis going forward, along with geographic expansion and product innovation.

On July 29, 2020, we signed an exclusive product supply and collaboration agreement with Ascend to commercialize a benchtop MALDI identification platform to complement the Company's expanded product offering plans. We continue our analytical and market evaluations of the Ascend benchtop MALDI identification platform. We have limited experience implementing third-party product commercialization agreements. There are, therefore, uncertainties regarding market demand, market acceptance, supply constraints, FDA authorization, ramp up expenditures, and other factors impacting market penetration.

On July 7, 2021, we announced the launch of a new configuration of our PhenoTest BC kit in the United States providing AST without ID. On August 3, 2021, we announced that this new AST only configuration had been CE marked for use in Europe. We believe this new AST only configuration may be attractive to prospective customers who already have a rapid ID system but who still need fast susceptibility results to support getting patients on an optimal antibiotic therapy as soon as possible.

COVID-19 Update

In late 2019, a novel strain of coronavirus (COVID-19) was reported to have surfaced in Wuhan, China, which has since spread globally. In March 2020, the World Health Organization declared COVID-19 a global pandemic. Further, the COVID-19 outbreak has resulted in government authorities around the world implementing numerous measures to try to reduce the spread of COVID-19, such as travel bans and restrictions, quarantines, shelter-in-place, stay-at-home or total lock-down (or similar) orders and business limitations and shutdowns. For example, the State of Arizona has implemented several orders promoting physical distancing, limiting certain activities, and restricting the operations of certain retail businesses. More recently, many news agencies have reported the spread of new variants of COVID-19, such as the Delta variant. The spread of these new strains are

34

causing many government authorities to reimplement the aforementioned measures to try to reduce the spread that had become less prevalent.

The COVID-19 pandemic and these measures have caused, and are continuing to cause, business slowdowns or shutdowns in affected areas, both regionally and worldwide, which have significantly impacted our business and results of operations, starting in the first quarter of 2020. For example, this included diminished access to our customers, including hospitals, which has severely limited our ability to sell and, to a lesser degree, implement the Accelerate Pheno systems. Our commercial access to customers has improved in some regions, with access in other regions remaining limited. In addition, in certain months with high rates of COVID-19 hospitalization our Accelerate PhenoTest BC kit orders declined as many hospitals curtailed elective surgeries to respond to COVID-19. For the three months ended June 2021, our Accelerate PhenoTest BC kit orders were at normal levels after the higher levels of COVID-19 hospitalization contributed to irregular ordering patterns, but could decline again if surges in COVID-19 cases cause hospitals to again reduce or prohibit elective surgeries. The emergence of the significantly more contagious Delta variant of COVID-19 in the United States and in EMEA and the prevalence of breakthrough cases of infection among fully vaccinated people adds additional uncertainty regarding our access to our customers and prospects, demand for our products, and ability to implement our products.

The reduced sales and implementations caused by the COVID-19 pandemic lowered our realized and expected revenue growth for 2020 and 2021.

As a medical device company, we have not experienced any disruptions to our ability to manufacture our products at our Tucson, Arizona headquarters under the various State of Arizona executive orders relating to the COVID-19 pandemic because we were classified as an essential service. We currently expect that, should future orders be issued, we would be able to sustain our essential operations. Our third-party manufacturing supply chain for Accelerate Pheno systems and consumable test kits remains stable. However, like many industries experiencing inflationary pressures in raw materials, the direct costs to manufacture our products are increasing and delivery schedules elongating. Our ability to pass increased material costs to many of our customers is limited because of long-term sales agreements with limits on price increases. Accordingly, we are closely monitoring the ability of all our suppliers to provide us with necessary materials and services at reasonable costs.

Additionally, the Company received loan proceeds of approximately $4.8 million under the Paycheck Protection Program established under the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. During January 2021, the Company submitted its application for forgiveness to the loan provider, and on July 15, 2021, the Small Business Administration (“SBA”) informed the Company of its full forgiveness in the amount of $4.8 million. For additional information about the loan, refer to Part I, Item 1, Note 9, Long-Term Debt and Note 19, Subsequent Events in this Form 10-Q.

We continue to monitor the evolving impacts to our business caused by the COVID-19 pandemic, including the significantly more contagious COVID-19 Delta variant. We may take further actions required by governmental authorities or that we determine are prudent to support the well-being of our employees, customers, suppliers, business partners and others. The degree to which the COVID-19 pandemic ultimately impacts our business, results of operations, cash flows and financial position will depend on future developments, which are highly uncertain, continuously evolving and cannot be predicted. This includes, but is not limited to, the duration and spread of the pandemic, its severity, the actions to contain the virus or treat its impact, the level and effectiveness of vaccinations, vaccination hesitancy impeding herd immunity, the emergence of new COVID-19 variants, such as the Delta variant, the financial impact of COVID-19 on hospitals, including their budget priorities, and how quickly and to what extent normal economic and operating conditions can resume.

Accordingly, our current results and financial condition discussed herein may not be indicative of future operating results and trends. Refer to the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, for additional risks we face due to the COVID-19 pandemic.

Changes in Results of Operations: Three and six months ended June 30, 2021, compared to three and six months ended June 30, 2020

The Company has provided enhanced information in a tabular format which presents some of the captions presented on the statement of operations, less non-cash equity-based compensation expense. These figures are reconciled to the statement of operations and are intended to add additional clarity on the operating performance of the business. The Company believes providing such figures less non-cash equity-based compensation expense provides helpful information for investors in understanding and evaluating our operating results in the same manner as our management and our board of directors.

For the three months ended June 30, 2021, gross profit increased as compared to the three months ended June 30, 2020. This increase was primarily due to an increase in sales of Accelerate PhenoTest BC revenue as our installed base for our instruments grew compared to the prior year period. The increase was partially offset by increases in costs to manufacture consumables due to pandemic-related inflationary factors and a decrease in our average unit sales price period over period. Gross profit less non-cash equity based compensation increased for the three months ended June 30, 2021 compared to the three months ended June 30, 2020, which was partially offset by an increase in non-cash equity-based compensation expense.

For the six months ended June 30, 2021, gross profit decreased as compared to the six months ended June 30, 2020. The decrease was primarily due to increases in the costs to manufacture consumables due to pandemic-related inflationary factors and a decrease in our average unit sales price period over period. This decrease was partially offset by an increase in sales of Accelerate PhenoTest BC revenue as our installed base for

36

our instruments grew compared to the prior year period. Gross profit less non-cash equity based compensation decreased for the six months ended June 30, 2021 compared to the six months ended June 30, 2020 due to an increase in non-cash equity-based compensation expense.

Research and development expenses for the three and six months ended June 30, 2021 increased compared to the three and six months ended June 30, 2020 primarily due to increases in non-cash equity-based compensation expense resulting from an increased number of RSUs granted and performance based stock awards becoming probable or achieved, compared to the prior year periods. For the three and six months ended June 30, 2021, research and development expenses less non-cash equity-based compensation decreased due to improved internal efficiencies and reductions in external study fees compared to the prior year periods.

Sales, general and administrative expense for the three and six months ended June 30, 2021 increased as compared to the three and six months ended June 30, 2020 primarily due to increases in non-cash equity-based compensation expense resulting from an increased number of restricted stock units granted and performance based stock awards becoming probable or achieved, compared to the prior year periods. For the three and six months ended June 30, 2021, sales, general and administrative expenses less non-cash equity-based compensation decreased due to lower ordinary compensation, travel, trade shows and instrument demonstration expenses compared to the prior year periods.

37

For the three and six months ended June 30, 2021, our loss from operations increased as compared to the three and six months ended June 30, 2020 primarily due to higher non-cash equity-based compensation expense partially offset by higher revenues and lower costs compared to the prior year periods. For the three and six months ended June 30, 2021, loss from operations less non-cash equity-based compensation decreased due to the continued benefit of cost cutting measures taken during 2020 and 2021.

This loss and further losses are anticipated and was the result of our continued investments in sales and marketing, key research and development personnel, related costs associated with product development, and commercialization of the Company’s products.

Other expense, net for the three and six months ended June 30, 2021 increased as compared to the three and six months ended June 30, 2020. The increase was primarily the result of decreased interest income and increased interest expense for the three and six months ended June 30, 2021.

For the three months ended June 30, 2021 and 2020, the Company incurred interest expense associated with our convertible notes of $4.2 million and $3.8 million, respectively. For the six months ended June 30, 2021 and 2020, the Company incurred interest expense associated with our convertible notes of $8.2 million and $7.6 million, respectively. These amounts were partially offset by investment income for the three and six months ended June 30, 2021 and 2020, respectively.

For the three and six months ended June 30, 2021 and 2020, the Company did not carry an income tax provision amount as the Company does not recognize tax benefits from current year tax losses in the U.S. and other foreign jurisdictions.

Capital Resources and Liquidity

Our primary source of liquidity has been from sales of shares of common stock, the issuance of our convertible notes and cash from operations. As of June 30, 2021, the Company had $68.9 million in cash and cash equivalents and investments, an increase of $0.6 million from $68.3 million at December 31, 2020. The primary reason for the increase was from cash provided by the issuance of common stock partially offset by cash used in operating activities. For additional information about the issuance of common stock, see “Sales of common stock” below.

The Company is subject to lease agreements. The future minimum lease payments under these lease agreements are included in Part I, Item 1, Note 15, Leases.

As of June 30, 2021, management believes that current cash balances will be sufficient to fund our capital and liquidity needs for the next twelve months.

Our primary use of capital has been for the development and commercialization of the Accelerate Pheno system and development of complementary products. We believe our capital requirements will continue to be met with our existing cash balance and those provided by revenue, grants, exercises of stock options and/or additional issuance of equity or debt securities. However, if capital requirements vary materially from those currently planned, or if our business is negatively impacted by the COVID-19 pandemic more seriously or for longer than we currently

38

expect, we may require additional capital sooner than expected. There can be no assurance that such capital will be available in sufficient amounts or on terms acceptable to us, if at all. Additional issuances of equity or convertible debt securities will result in dilution to our current common stockholders.

Summary of Cash Flows

The following summarizes selected items in the Company’s condensed consolidated statements of cash flows for the six months ended June 30, 2021 and 2020:

Cash Flow Summary
	Six Months Ended June 30,
	(in thousands)
	2021		2020		$ Change
Net cash used in operating activities	$	(22,928)	$	(27,395)	$	4,467
Net cash provided by investing activities	8,265		5,692		2,573
Net cash provided by financing activities	23,505		8,038		15,467

Cash flows from operating activities

The net cash used in operating activities was $22.9 million and $27.4 million for the six months ended June 30, 2021 and 2020, respectively. Net cash used in operating activities was primarily the result of net losses partially offset by equity-based compensation and amortization of debt discount and issuance costs. These losses are the result of continued investments in research and development to further mature the Accelerate Pheno, system and develop a ancillary and next generation products, sales and marketing, along with other factors. An increase in non-cash expenses for the six months ended June 30, 2021 compared to the six months ended June 30, 2020 resulted in a decrease in cash used in operating activities for the current period.

Cash flows from investing activities

The net cash provided by investing activities was $8.3 million for the six months ended June 30, 2021. During the six months ended June 30, 2021, the Company had maturities of marketable securities of $24.0 million, which were offset in part by purchases of marketable securities of $15.7 million. The net cash provided by investing activities was $5.7 million for the six months ended June 30, 2020. During the six months ended June 30, 2020, the Company had maturities of marketable securities of $27.8 million, which were offset in part by purchases of marketable securities of $21.5 million.

The Company had larger marketable securities purchases during the six months ended June 30, 2020 compared to the six months ended June 30, 2021, due to the Company reinvesting a larger portion of its cash and cash equivalents in debt securities available-for-sale during the six months ended June 30, 2020.

Cash flows from financing activities

The net cash provided by financing activities was $23.5 million and $8.0 million for the six months ended June 30, 2021 and 2020, respectively. During the six months ended June 30, 2021, the Company received $21.3 million in proceeds from the issuance of common stock in connection with the Company’s private placement offering and another $0.8 million in proceeds from the issuance of common stock in connection with the Company’s “at-the-market” equity offering program under its Equity Sales Agreement (the “Sales Agreement”) with William Blair & Company, L.L.C. (“William Blair”). This resulted in an increase in net cash provided by financing activities for the six months ended June 30, 2021 compared to the prior year period. For additional information about the issuance of common stock, refer to Part I, Item 1, Note 17, Stockholders’ Equity in this Form 10-Q.

Convertible Notes

On March 27, 2018, the Company issued $150.0 million aggregate principal amount of 2.50% Convertible Senior Notes (“Notes”). In connection with the offering of the Notes, the Company granted the initial purchasers of the Notes a 13-day option to purchase up to an additional $22.5 million aggregate principal amount of the Notes on the same terms and conditions. On April 4, 2018 the option was partially exercised, which resulted in $21.5 million

39

of additional proceeds, for total proceeds of $171.5 million. The Notes mature on March 15, 2023, unless earlier repurchased or converted into shares of common stock subject to certain conditions. Upon conversion of the Notes, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock, at the Company's election. The initial conversion rate of the Notes is 32.3428 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $30.92 per share of common stock, subject to adjustment. We pay interest on the Notes semi-annually in arrears on March 15 and September 15 of each year with interest payments beginning on September 15, 2018. Proceeds received from the issuance of the Notes were allocated between long-term debt (the “liability component”) and contributed capital (the “equity component”), within the condensed consolidated balance sheet. The fair value of the liability component was measured using rates determined for similar debt instruments without a conversion feature. For additional information about the Notes, refer to Part I, Item 1, Note 10, Convertible Notes in this Form 10-Q.

In connection with the offering, we entered into a prepaid forward stock repurchase transaction (the “Prepaid Forward”) with a financial institution. Pursuant to the Prepaid Forward, we used approximately $45.1 million of the proceeds from the offering of the Notes to pay the prepayment amount. The aggregate number of our common stock underlying the Prepaid Forward is approximately 1,858,500 shares (based on the sale price of $24.25). The expiration date for the Prepaid Forward is March 15, 2023, although it may be settled earlier in whole or in part. Upon settlement of the Prepaid Forward, at expiration or upon any early settlement, the Forward Counterparty will deliver to us the number of shares of common stock underlying the Prepaid Forward or the portion thereof being settled early. The shares purchased under the Prepaid Forward were treated as treasury stock on the condensed consolidated balance sheet (and not outstanding for purposes of the calculation of basic and diluted earnings per share), but remain outstanding for corporate law purposes, including for purposes of any future stockholders' votes, until the Forward Counterparty delivers the shares underlying the Prepaid Forward to us.

Paycheck Protection Program (PPP) Loan

On April 14, 2020, the Company entered into a promissory note (the “PPP Note”) evidencing an unsecured loan in the amount of $4.8 million. The PPP Note matured on April 14, 2025 and bears interest at a rate of 1% per annum. Beginning August 14, 2021, the Company is required to make 45 monthly payments of principal and interest in the amount of $0.1 million. The PPP Note could be prepaid by the Company at any time prior to maturity with no prepayment penalties. The proceeds from the PPP Note could only be used for payroll costs (including benefits), interest on mortgage obligations, rent, utilities and interest on certain other debt obligations. For additional information about the PPP Note, refer to Part I, Item 1, Note 9, Long-Term Debt in this Form 10-Q.

Pursuant to the terms of the CARES Act and the PPP, the Company could apply to the lender for forgiveness for the amount due on the Loan. The amount eligible for forgiveness is based on the amount of loan proceeds used by the Company (during the 24 week period after the lender makes the first disbursement of loan proceeds) for the payment of certain covered costs, including payroll costs (including benefits), rent and utilities, subject to certain limitations and reductions in accordance with the CARES Act and the PPP. During January 2021, the Company submitted its application for forgiveness to the Lender. On July 15, 2021, the SBA informed the Company of its full forgiveness for the entire Loan amount plus accrued interest, which was $4.8 million as of June 30, 2021. The SBA’s determination of loan forgiveness does not preclude further investigation by the SBA according to its rules and regulations. For additional information about the PPP Note forgiveness, refer to Part I, Item 1, Note 19, Subsequent Events in this Form 10-Q.

Other notes payable

During the three months ended June 30, 2021, the Company entered into three loan agreements with two capital asset financing companies. Loan proceeds were $0.4 million, with interest rates ranging from 9.8% to 12.4 % and maturities ranging from January 1, 2022 to September 2022. For additional information about other notes payable, refer to Part I, Item 1, Note 9, Long-Term Debt in this Form 10-Q.

Sales of common stock

On May 28, 2021, the Company entered into the Sales Agreement with William Blair pursuant to which it may sell shares of the Company’s common stock having an aggregate offering price of up to $50 million, from time to time, through an “at-the-market” equity offering program under which William Blair will act as sales agent. Subject to the terms and conditions of the Sales Agreement, William Blair may sell shares by any method deemed

40

to be an “at-the-market” offering as defined in Rule 415 under the Securities Act. The Company is not obligated to sell any shares under the Sales Agreement. William Blair is entitled to a commission of 3% of the aggregate gross proceeds from each sale of shares occurring pursuant to the Sales Agreement. During the six months ended June 30, 2021, the Company sold 92,497 shares of common stock under the Sales Agreement at a price per share of $8.80 resulting in aggregate gross proceeds of $0.8 million.

On December 24, 2020, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain directors and officers of the Company, or entities affiliated or related to such persons, for the issuance and sale by the Company of an aggregate of 4,166,663 shares of the Company’s common stock to the purchasers for an aggregate purchase price of approximately $32 million. The agreement contemplates that the closing of the purchase and sale of the shares will occur in three approximately equal tranches on the dates as specified in the agreement or such other dates as the parties may agree, with the first and second tranches having closed on February 19, 2021 and April 9, 2021, respectively. During the six months ended June 30, 2021, the Company sold 2,777,772 shares of common stock under the Securities Purchase Agreement in first and second tranches at a price per share of $7.68 resulting in aggregate gross proceeds of $21.3 million.

For additional information about the issuance of common stock, refer to Part I, Item 1, Note 17, Stockholders’ Equity in this Form 10-Q.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of June 30, 2021.

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 with U.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 accounts receivable, inventories, property and equipment, intangible assets, accruals, warranty liabilities, tax valuation accounts 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 and are 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 ended December 31, 2020.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not required for a smaller reporting company.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on an evaluation under the supervision and with the participation of the Company’s management, the Company’s Principal Executive Officer and Principal Financial Officer have concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of June 30, 2021, to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to the Company’s management, including its Principal Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There was no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2021 that materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

42

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

We are from time to time subject to various claims and legal actions in the ordinary course of our business. We believe that there are currently no claims or legal actions that would reasonably be expected to have a material adverse effect on our results of operations or financial condition.

Item 1A. Risk Factors

In addition to the other information set forth in this Form 10-Q, you should carefully consider the risks discussed in the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020. The risks described in our Annual Report on Form 10-K for the year ended December 31, 2020 are not the only risks facing the Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect our business, results of operations, cash flows and financial position.

Additional Risk Related to Our Business and Strategy

Disruptions in the supply of raw materials, consumable goods or other key product components, or issues associated with their quality from our single source suppliers, could result in a significant disruption in sales and profitability.

We must manufacture or engage third parties to manufacture components of our products in sufficient quantities and on a timely basis, while maintaining product quality, acceptable manufacturing costs and complying with regulatory requirements. Our components are custom-made by only a few outside suppliers. In certain instances, we have a sole source supply for key product components of the Accelerate Pheno system. We may be unable to satisfy our forecast demand from existing suppliers for our products, or we may be unable to find alternative suppliers for key product components or ancillary items at reasonably comparable prices. If this occurs, we may be unable to manufacture our products and/or meet our customers’ needs in a timely manner or at all.

Additionally, we have entered into supply agreements with most of our suppliers to help ensure component availability and flexible purchasing terms with respect to the purchase of such components. If our suppliers discontinue production of a key component for one or more of our products, we may be unable to identify or secure a viable alternative on reasonable terms, or at all, which could limit our ability to manufacture our products. While we may be able to modify our product candidates to utilize a new source of components, we may need to secure marketing authorization from the FDA or other regulatory clearance for the modified product, and it could take considerable time and expense to perform the requisite tasks prior to seeking such authorization.

In determining the required quantities of our products and our manufacturing schedule, we will need to make significant judgments and estimates regarding factors such as market trends and any seasonality with respect to our sales. Because of the inherent nature of estimates, there could be significant differences between our estimates and the actual amounts of products that we require. This can result in shortages if we fail to anticipate demand, or excess inventory and write-offs if we order more than we need.

Reliance on third-party manufacturers entails risk to which we would not be subject if we manufactured these components ourselves, including:

•reliance on third parties for regulatory compliance and quality assurance;

•possible breaches of manufacturing agreements by the third parties because of factors beyond our control;

•possible regulatory violations or manufacturing problems experienced by our suppliers;

•possible termination or non-renewal of agreements by third parties, based on their own business priorities, at times that are costly or inconvenient for us;

43

•the potential obsolescence and/or inability of our suppliers to obtain required components;

•the potential delays and expenses of seeking alternate sources of supply or manufacturing services;

•the inability to qualify alternate sources without impacting performance claims of our products;

•reduced control over pricing, quality and timely delivery due to the difficulties in switching to alternate suppliers or assemblers; and

•increases in prices of raw materials and key components.

We are currently experiencing unprecedented cost increases from many of our suppliers. The areas of cost increases include raw materials, components, and value-add supplier labor. We currently have sufficient inventory of Accelerate Pheno devices to limit the impact of cost increases on such devices. However, we are being impacted by cost increases to components and raw materials necessary for the production of our Accelerate Pheno kits. Our kits require these components and raw materials, and many of our supply contracts permit the supplier to pass on certain inflation increases to us. Moreover, our ability to pass on cost increases to our consumable kit customers is limited by long-term contractual price commitments. Prolonged elevated supply costs and further cost increases may eventually impact our cost to manufacture our Accelerate Pheno devices. The supply cost increases we are experiencing and may experience in the future may materially reduce our gross profit margins, thereby negatively impact our overall financial results.

The manufacturing operations for the Accelerate Pheno system use highly technical processes involving unique, proprietary techniques. In addition, the manufacturing equipment we use would be costly to repair or replace and could require substantial lead time to repair or replace. Any interruption in our operations or decrease in the production capacity of our manufacturing facility or the facilities of any of our suppliers because of equipment failure, natural disasters such as earthquakes, tornadoes and fires, or otherwise, would limit our ability to meet customer demand for our products. In the event of a disruption, we may lose customers and we may be unable to regain those customers thereafter. Our insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all.

Accounting Policies [Abstract]

Organization and Nature of Business; Basis of Presentation; Principles of Consolidation; Significant Accounting Policies

NOTE 1. ORGANIZATION AND NATURE OF BUSINESS; BASIS OF PRESENTATION; PRINCIPLES OF CONSOLIDATION; SIGNIFICANT ACCOUNTING POLICIES

Accelerate Diagnostics, Inc. (“we” or “us” or “our” or “Accelerate” or the “Company”) is an in vitro diagnostics company dedicated to providing solutions that improve patient outcomes and lower healthcare costs through the rapid diagnosis of serious infections.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as filed with the SEC on March 2, 2021.

The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited financial statements as of that date but does not include all disclosures such as notes required by U.S. GAAP.

The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the entire year ending December 31, 2021, or any future period.

All amounts are rounded to the nearest thousand dollars unless otherwise indicated.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after elimination of intercompany transactions and balances.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to accounts receivable, inventory, property and equipment, accrued liabilities, warranty liabilities, tax valuation accounts, equity–based compensation, revenue and leases. Actual results could differ materially from those estimates.

Estimated Fair Value of Financial Instruments

The Company follows Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, which has defined fair value and requires the Company to establish a framework for measuring and disclosing fair value. The framework requires the valuation of assets and liabilities subject to fair value measurements using a three-tiered approach and fair value measurement to be classified and disclosed in one of the following three categories:

•Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

•Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;

•Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).

The carrying amounts of financial instruments such as cash and cash equivalents, trade accounts receivable, prepaid expenses, other current assets, accounts payable, accrued liabilities, and other current liabilities approximate the related fair values due to the short-term maturities of these instruments.

The estimated fair value of the Company’s convertible note represents a Level 2 measurement. See Note 10, Convertible Notes for further detail on the Company’s convertible notes.

The estimated fair value of the Company’s long-term debt represents a Level 3 measurement. The promissory notes issued under the Paycheck Protection Program (PPP) and other long-term debt is privately held with no public market. The carrying amount of these notes approximates fair value. See Note 9, Long-Term Debt for further detail on the Company’s long-term debt.

Cash and Cash Equivalents

All highly liquid investments with an original maturity of three months or less at time of purchase are considered to be cash equivalents. Cash and cash equivalents include overnight repurchase agreement accounts and other investments. As part of our cash management process, excess operating cash is invested in overnight repurchase agreements with our bank. Repurchase agreements and other investments classified as cash and cash equivalents are not deposits and are not insured by the U.S. Government, the FDIC or any other government agency and involve investment risk including possible loss of principal. We believe, however, that the market risk arising from holding these financial instruments is minimal.

Investments

The Company invests in various debt and equity securities which are primarily held in the custody of major financial institutions. Debt securities consist of certificates of deposit, U.S. government and agency securities, commercial paper, and corporate notes and bonds. Equity securities consist of mutual funds. The Company records these investments in the condensed consolidated balance sheet at fair value. Unrealized gains or losses for debt securities available-for-sale are included in accumulated other comprehensive income, a component of stockholders’ deficit. Unrealized gains or losses for equity securities are included in other income (expense), net. The Company considers all debt securities available-for-sale, including those with maturity dates beyond 12 months, as available to support current operational liquidity needs. The Company classifies its investments as current based on the nature of the investments and their availability for use in current operations.

We perform an assessment to determine whether there have been any events or economic circumstances to indicate that a debt security available-for-sale in an unrealized loss position has suffered impairment as a result of credit loss or other factors. A debt security is considered impaired if its fair value is less than its amortized cost basis at the reporting date.

If we intend to sell the debt security or if it is more-likely-than-not that we will be required to sell the debt security before the recovery of its amortized cost basis, the impairment is recognized and the unrealized loss is recorded as a direct write-down of the security's amortized cost basis with an offsetting entry to earnings. If we do not intend to sell the debt security or believe we will not be required to sell the debt security before the recovery of its amortized cost basis, the impairment is assessed to determine if a credit loss component exists. We use a discounted cash flow method to determine the credit loss component. In the event a credit loss exists, an allowance for credit losses is recorded in earnings for the credit loss component of the impairment while the remaining portion of the impairment attributable to factors other than credit loss is recognized, net of tax, in accumulated other comprehensive income. The amount of impairment recognized due to credit factors is limited to the excess of the amortized cost basis over the fair value of the security.

Inventory

Inventory is stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first out method. The Company estimates the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. The Company periodically analyzes its inventory levels to identify inventory that may expire prior to expected sale or has a cost basis in excess of its estimated realizable value and records a charge to expense for such inventory as appropriate.

Accounts Receivable

Accounts receivable consist of amounts due to the Company for sales to customers and are based on what we expect to collect in exchange for goods and services. Receivables are considered past due based on the contractual payment terms and are written off if reasonable collection efforts prove unsuccessful.

We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the condensed consolidated statements of operations. We assess collectibility by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when we identify specific customers with known disputes or collectibility issues. In determining the amount of the allowance for credit losses, we consider historical collectibility and make judgments about the creditworthiness of customers based on credit evaluations. Our customers typically have good credit quality. We also consider customer-specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. The allowance for credit losses at June 30, 2021 and December 31, 2020 was $0.2 million and $0.4 million, respectively.

The allowance for credit losses for the three and six months ended June 30, 2021 and 2020 is comprised of the following (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Beginning balance	$	209	$	110	$	445	$	—
Provisions	7		(12)		38		98
Write-offs	(3)		43		(270)		43
Recoveries	—		—		—		—
Ending balance	$	213	$	141	$	213	$	141

The write-offs recorded during the six months ended June 30, 2021 were in connection with a one time restructuring activity of the Company's Europe, Middle East and Africa (“EMEA”) business. These credit losses were incurred as part of the Company terminating agreements with select distributors in geographies it exited and did not pursue collection of these accounts receivables. The credit losses and bad debt expense was accrued as of December 31, 2020.

Property and Equipment

Property and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred and expenditures for major improvements are capitalized. Gains and losses from retirement or replacement are included in costs and expenses. Depreciation of property and equipment is computed using the straight-line method over the estimated useful life of the assets, ranging from one to seven years. Leasehold improvements are depreciated over the remaining life of the lease or the life of the asset, whichever is less.

Instruments Classified as Property and Equipment

Property and equipment includes Accelerate Pheno systems (also referred to as instruments) used for sales demonstrations, instruments under rental agreements and instruments used for research and development. Depreciation expense for instruments used for sales demonstrations is recorded as a component of sales, general and administrative expense. Depreciation expense for instruments placed at customer sites pursuant to reagent

rental agreements is recorded as a component of cost of sales. Depreciation expense for instruments used in our laboratory and research is recorded as a component of research and development expense. The Company retains title to these instruments and depreciates them over five years. Losses from the retirement of returned instruments are included in costs and expenses.

The Company evaluates the recoverability of the carrying amount of its instruments whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, and this evaluation is performed at least annually. This evaluation is based on our estimate of future cash flows and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of instruments. No impairment charges have been recorded as of June 30, 2021 and December 31, 2020.

Long-lived Assets

Long-lived assets and certain identifiable intangibles to be held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company continuously evaluates the recoverability of its long-lived assets based on estimated future cash flows from and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of the long-lived asset.

Warranty Reserve

Instruments are typically sold with a one year limited warranty, while kits and accessories are typically sold with a sixty days limited warranty. Accordingly, a provision for the estimated cost of the limited warranty repair is recorded at the time revenue is recognized. Our estimated warranty provision is based on our estimate of future repair events and the related estimated cost of repairs. The Company periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary. The expense incurred for these provisions is included in cost of sales on the condensed consolidated statements of operations and comprehensive loss.

Warranty reserve activity for the three and six months ended June 30, 2021 and 2020 is as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Beginning balance	$	184	$	342	$	232	$	403
Provisions	12		—		(10)		—
Warranty cost incurred	(27)		(37)		(53)		(98)
Ending balance	$	169	$	305	$	169	$	305

Paycheck Protection Program (PPP) Loan

The PPP was established by the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act, through a significant expansion of the Small Business Administration (“SBA”) 7(a) loan program. On April 14, 2020, the Company entered into a promissory note (the “PPP Note”) evidencing an unsecured loan in the amount of $4.8 million.

The Company elected to account for the PPP Note in accordance with ASC 470, Debt, with interest accrued in accordance with the interest method under ASC 835-30, Imputation of Interest. The Company recognized the entire PPP Note amount as a liability on the balance sheet, with interest accrued and expensed over the term of the loan. The Company did not impute additional interest at a market rate because transactions where interest rates are prescribed by governmental agencies are excluded from the scope of ASC 835-30.

The PPP Note remains a liability until either of the following criteria are met:

•the Company is legally released from being the primary obligor under the liability (i.e. the PPP Note is forgiven); or

•the Company pays the lender and is relieved of its obligation for the liability

In January 2021, the Company submitted its application for forgiveness to the loan provider, and on July 15, 2021, the SBA informed the Company of its full forgiveness in the amount of $4.8 million. See Note 9, Long-Term Debt and Note 19, Subsequent Events for further detail regarding the PPP Note.

Convertible Notes

The Company accounts for convertible debt instruments that may be settled in cash or equity upon conversion, which includes the 2.50% Senior Convertible Notes due 2023 (the “Notes”), by separating the liability and equity components of the instruments in a manner that reflects our nonconvertible debt borrowing rate. The Company determined the carrying amount of the liability component of the Notes by using estimates and assumptions that market participants would use in pricing a debt instrument. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component, and the associated non-cash interest expense.

The equity component is treated as a discount on the liability component of the Notes, which is amortized over the term of the Notes using the effective interest rate method. Debt issuance costs related to the Notes are allocated to the liability and equity components of the Notes based on their relative values. Debt issuance costs allocated to the liability component are amortized over the life of the Notes as additional non-cash interest expense. Transaction costs allocated to equity are netted with the equity component of the convertible debt instrument in stockholders’ deficit.

Revenue Recognition

The Company recognizes revenue when control of the promised good or service is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Sales taxes are excluded from revenues.

The Company determines revenue recognition through the following steps:

•Identification of the contract with a customer

•Identification of the performance obligations in the contract

•Determination of the transaction price

•Allocation of the transaction price to the performance obligations

•Recognition of revenue as we satisfy a performance obligation

Product revenue is derived from the sale or rental of our instruments and sales of related consumable products. When an instrument is sold, revenue is generally recognized upon installation of the unit consistent with contract terms, which do not include a right of return. When a consumable product is sold, revenue is generally recognized upon shipment. Invoices are generally issued when revenue is recognized and the term between invoicing and when payment is due is not typically significant.

Service revenue is derived from the sale of extended service agreements which are generally non-cancellable. This revenue is recognized on a straight-line basis over the contract term beginning on the effective date of the contract because the Company is standing ready to provide services. Invoices are generally issued annually and coincide with the beginning of individual service terms.

Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine relative standalone selling prices based on the price charged to customers for each individual performance obligation.

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The Company has determined these costs would have an amortization period of less than one year and has elected to recognize them as an expense when incurred. Contract asset opening and closing balances were immaterial for the three and six months ended June 30, 2021.

Cost of Sales

Cost of sales includes cost of materials, direct labor, equity-based compensation, facility and other manufacturing overhead costs for consumable tests and instruments sold to customers. Cost of sales for instruments also includes depreciation on revenue generating instruments that have been placed with our customers under a reagent rental agreement. Cost of sales includes repair and maintenance cost for instruments covered by a service agreement or instruments covered by a reagent rental agreement. Cost of sales also includes warranty related expenses.

Shipping and Handling

Shipping and handling costs billed to customers are included as a component of revenue. The corresponding expense incurred with third party carriers is included as a component of sales, general and administrative costs on the condensed consolidated statements of operations and comprehensive loss.

Leases

The Company accounts for commercial leases in accordance with ASC 842, Leases. We determine if an arrangement is or contains a lease and the type of lease at inception. The Company classifies commercial leases as finance leases (lessee) or sales-type leases (lessor) when there is either a transfer of ownership of the underlying asset by the end of the lease term, the lease contains an option to purchase the asset that we are reasonably certain will be exercised, the lease term is for the major part of the remaining economic life of the asset, the present value of the lease payments and any residual value guarantee equals or substantially exceeds all the fair value of the asset, or the asset is of such a specialized nature that it will have no alternative use to the lessor at the end of the lease term. Payments contingent on future events (i.e. based on usage) are considered variable and excluded from lease payments for the purposes of classification and initial measurement. Several of our leases include options to renew or extend the term upon mutual agreement of the parties and others include one-year extensions exercisable by the lessee. None of our leases contain residual value guarantees, restrictions, or covenants.

To determine whether a contract contains a lease, the Company uses its judgment in assessing whether the lessor retains a material amount of economic benefit from an underlying asset, whether explicitly or implicitly identified, which party holds control over the direction and use of the asset, and whether any substantive substitution rights over the asset exist.

Lessee

Operating leases are included in right-of-use (“ROU”) assets and operating lease liabilities within our consolidated balance sheets. These assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and their related liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Typically, we use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments. We use the implicit rate when readily determinable. ROU assets are net of lease payments made and exclude lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term, which may include options to extend or terminate the lease when it is reasonably certain that we will exercise the option. As of June 30, 2021 and December 31, 2020, the Company was not a party to finance lease arrangements.

Our operating leases consist primarily of leased office, factory, and laboratory space in the U.S. and office space in Europe, have between two and six-year terms, and typically contain penalizing, early-termination provisions.

Lessor

The Company leases instruments to customers under “reagent rental” agreements, whereby the customer agrees to purchase consumable products over a stated term, typically five years or less, for a volume-based price that includes an embedded rental for the instruments. When collectibility is probable, that amount is recognized as income at lease commencement for sales-type leases and as product is shipped, typically in a straight–line pattern, over the term for operating leases, which typically include a termination without cause or penalty provision given a short notice period.

Consideration is allocated between lease and non-lease components based on stand-alone selling price in accordance with ASC 606, Revenue from Contracts with Customers.

Net investment in sales-type leases are included within our condensed consolidated balance sheets as a component of other current assets and other non-current assets, which include the present value of lease payments not yet received and the present value of the residual asset, which are determined using the information available at commencement, including the lease term, estimated useful life, rate implicit in the lease, and expected fair value of the instrument.

Nonqualified Cash Deferral Plan

The Company's Cash Deferral Plan (the “Deferral Plan”), provides certain key employees, with an opportunity to defer the receipt of such participant's base salary. The Deferral Plan is intended to be a nonqualified deferred compensation plan that complies with the provisions of Section 409A of the Internal Revenue Code. All of the investments held in the Deferral Plan are equity securities consisting of mutual funds and recorded at fair value with changes in the investments' fair value recognized as earnings in the period they occur. The corresponding liability for the Deferral Plan is included in other non-current liabilities in the condensed consolidated balance sheet.

Equity-Based Compensation

The Company may award stock options, restricted stock units (“RSUs”), performance-based awards, and other equity-based instruments to its employees, directors and consultants. Compensation cost related to equity-based instruments is based on the fair value of the instrument on the grant date, and is recognized over the requisite service period on a straight-line basis over the vesting period for each tranche (an accelerated attribution method) except for performance-based awards. Performance-based awards vest based on the achievement of performance targets. Compensation costs associated with performance-based awards are recognized over the requisite service period based on probability of achievement. Performance-based awards require management to make assumptions regarding the likelihood of achieving performance targets.

The Company estimates the fair value of service based and performance based stock option awards, including modifications of stock option awards, using the Black-Scholes option pricing model. This model derives the fair value of stock options based on certain assumptions related to expected stock price volatility, expected option life, risk-free interest rate and dividend yield.

•Volatility: The expected volatility is based on the historical volatility of the Company's stock price over the most recent period commensurate with the expected term of the stock option award.

•Expected term: The estimated expected term for employee awards is based on the calculation published by the SEC in SAB110 for use when there is not a sufficient history of employee exercise patterns. For consultant awards, the estimated expected term is the same as the life of the award.

•Risk-free interest rate: The risk-free interest rate is based on published U.S. Treasury rates for a term commensurate with the expected term.

•Dividend yield: The dividend yield is estimated as zero as the Company has not paid dividends in the past and does not have any plans to pay any dividends in the foreseeable future.

The Company records the fair value of RSUs or stock grants based on published closing market price on the day before the grant date. The Company accounts for forfeitures as they occur rather than on an estimated basis.

Deferred Tax

Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying balance sheets. The change in deferred tax assets and liabilities for the period represents the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws in deferred tax assets and liabilities are reflected as an adjustment to the tax provision or benefit in the period of enactment.

The Company follows the provisions of ASC 740, Income Taxes, to account for any uncertainty in income taxes with respect to the accounting for all tax positions taken (or expected to be taken) on any income tax return. This guidance applies to all open tax periods in all tax jurisdictions in which the Company is required to file an income tax return. Under U.S. GAAP, in order to recognize an uncertain tax benefit, the taxpayer must be more likely than not certain of sustaining the position, and the measurement of the benefit is calculated as the largest amount that is more likely than not to be realized upon resolution of the position. Interest and penalties, if any, would be recorded within tax expense.

Foreign Currency Translation and Foreign Currency Transactions

Adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars are included in the foreign currency translation adjustment, a component of accumulated other comprehensive income loss.

The Company has assets and liabilities, including receivables and payables, which are denominated in currencies other than their functional currency. These balance sheet items are subject to re-measurement, the impact of which is recorded in foreign currency exchange gain and loss, within the condensed consolidated statement of operations and comprehensive loss.

Loss Per Share

Basic loss per share includes no dilution and is computed by dividing loss available to common stockholders by the weighted average number of common shares outstanding for the period. Potentially dilutive common shares consist of shares issuable from stock options and unvested RSUs. Potentially dilutive common shares would also include common shares that would be outstanding if the Notes at the balance sheet date were converted and shares issuable in connection with a securities purchase agreement. Diluted earnings are not presented when the effect of adding such additional common shares is antidilutive.

Comprehensive Loss

In addition to net loss, comprehensive loss includes all changes in equity during a period, except those resulting from investments by and distributions to owners. The Company holds investments classified as debt securities available-for-sale and records the change in fair market value as a component of comprehensive loss. The Company also has adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars which is included as a component of comprehensive loss.

Accounting Changes and Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

NOTE 2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Standards that were recently adopted

In January 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the FASB Emerging Issues Task Force). ASU 2020-01 clarifies the interaction of the accounting for equity securities under Topic 321, the accounting for the equity method investments in Topic 323 and the accounting for certain forward contracts and purchased options in Topic 815. The Company adopted ASU 2020-01 on January 1, 2021, which had no impact to our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740); Simplifying the Accounting for Income Taxes. ASU 2019-12 reduces complexity in the accounting standard. The Company adopted ASU 2019-12 on January 1, 2021, which had no impact to our consolidated financial statements. The Company maintains a full valuation allowance against its net deferred tax assets. The valuation allowance is based on management’s assessment that it is more likely than not that the Company will not have taxable income in the foreseeable future.

Standards not yet adopted

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 reduces the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. In addressing the complexity, this ASU amends the guidance on convertible instruments and the guidance on the derivatives scope exception for contracts in an entity’s own equity. This ASU will reduce the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP standards. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. This ASU is effective for us on January 1, 2022, with early adoption permitted. We are currently assessing the impact this will have on our consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2021-04 will codify the final consensus reached by the Emerging Issues Task Force (EITF) on how an issuer should account for modifications made to equity-classified written call options (hereafter referred to as a warrant to purchase the issuer’s common stock). The guidance in the ASU requires the issuer to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange of the original warrant for a new warrant. This guidance applies whether the modification is structured as an amendment to the terms and conditions of the warrant or as termination of the original warrant and issuance of a new warrant. This ASU is effective for us on January 1, 2022, with early adoption permitted. We are currently assessing the impact this will have on our consolidated financial statements, and believe it will not have an impact on the Company's consolidated financial statements at January 1, 2022.

Risks and Uncertainties [Abstract]

Concentration of Credit Risk

NOTE 3. CONCENTRATION OF CREDIT RISK

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, short-term investments and accounts receivable.

The Company has financial institutions for banking operations that hold 10% or more of the Company’s cash and cash equivalents. As of June 30, 2021, three of the Company's financial institutions held 61%, 16% and 13% of the Company’s cash and cash equivalents, respectively. As of December 31, 2020, three of the Company's financial institutions held 53% and 14% and 16% of the Company’s cash and cash equivalents, respectively.

The Company grants credit to domestic and international customers. Exposure to losses on accounts receivable is principally dependent on each client's financial position. None of the Company's customers accounted for 10% or more of the net accounts receivable balance as of June 30, 2021 and December 31, 2020.

Customers who represented 10% or more of the Company’s total revenue for the three and six months ended June 30, 2021 and 2020 were as follows:

	Three Months Ended June 30,			Six Months Ended June 30,

Highly liquid investments with an original maturity of three months or less at time of purchase are included in cash and cash equivalents on the condensed consolidated balance sheet.

Level 1 assets are priced using quoted prices in active markets for identical assets which include money market funds, U.S. Treasury securities and mutual funds as these specific assets are liquid.

Level 2 available-for-sale securities are priced using quoted market prices for similar instruments or nonbinding market prices that are corroborated by observable market data. The Company uses inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, independent pricing vendors, or other sources, to determine the ultimate fair value of these assets and liabilities. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs.

In 2018, the Company issued the Notes, for total proceeds of $171.5 million, as described in Note 10, Convertible Notes. At June 30, 2021 and December 31, 2020, the fair value of the Notes were $112.7 million and $98.7 million, respectively. The fair value of the Notes is highly correlated to the Company’s stock price and as a result, significant changes to the Company’s stock price will have a significant impact on the calculated fair value. The fair value of the Notes are classified as Level 2 within the fair value hierarchy. See Note 10, Convertible Notes for further detail on the Company’s convertible notes.

The Company's PPP Note along with its other long-term notes, cumulatively $5.3 million, approximate their fair value. The estimated fair value of the Company’s long-term debt represents a Level 3 measurement. See Note 9, Long-Term Debt for further detail on the Company's long-term debt.

Deferred Revenue and Remaining Performance Obligations

NOTE 8. DEFERRED REVENUE AND REMAINING PERFORMANCE OBLIGATIONS

Deferred revenue consists of amounts received for products or services not yet delivered or earned. If we anticipate revenue will not be earned within the following twelve months, the amount is reported as other non-current liabilities. A summary of the balances as of June 30, 2021 and December 31, 2020 follows (in thousands):

	June 30,		December 31,
	2021		2020
Products and services not yet delivered	$	282	$	376

We recognized $0.2 million and $0.3 million of revenues that were included in the beginning contract liabilities balances during the three and six months ended June 30, 2021, respectively, and $0.1 million and $0.2 million of revenues that were included in the beginning contract liabilities balances during the three and six months ended June 30, 2020, respectively. No material amount of revenue recognized during the period was from performance obligations satisfied in prior periods.

Transaction Price Allocated to Remaining Performance Obligations

As of June 30, 2021, $10.9 million of revenue is expected to be recognized from remaining performance obligations. This balance primarily relates to product shipments for reagents sold to customers under sales-type lease agreements. These agreements have between two and four year terms and revenue is recognized as product is shipped, typically on a straight-line basis. The remaining balance relates to executed service contracts that begin as warranty periods expire. These service contracts typically provide for four-year terms and revenue is recognized on a straight-line basis.

The Company elects not to disclose the value of unsatisfied performance obligations for (i) contracts with an expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

The Company entered into three loan agreements with two capital asset financing companies. Loan proceeds were $0.8 million, with interest rates ranging from 9.8% to 12.4% and maturities ranging from January 1, 2022 to September 2022. As of June 30, 2021, the current portion of long-term debt was $0.3 million and long-term debt was $0.1 million.

PPP Loan

On April 14, 2020, the Company entered into the PPP Note evidencing an unsecured loan in the amount of $4.8 million made to the Company under the PPP. The PPP was established under the CARES Act and is administered by the SBA.

On September 3, 2020 the Company's loan provider amended the PPP Note per the Paycheck Protection Program Flexibility Act (“PPP Flexibility Act”), which was enacted after the PPP Note was approved and funded. The PPP Flexibility Act amended the CARES Act to require that all PPP Note's made prior to June 5, 2020 be extended to a 5-year term. In accordance with this amendment the PPP Notes' original maturity date of April 14, 2022 was amended to April 14, 2025. The original terms of the loan required 18 monthly payments of principal and interest in the amount of $0.3 million starting November 14, 2020. The amended terms required 45 monthly payments of principal and interest in the amount of $0.1 million starting August 14, 2021. The PPP Note's interest rate was unchanged and bears an interest at a rate of 1% per annum.

The PPP Note could be prepaid by the Company at any time prior to maturity with no prepayment penalties. The proceeds from the PPP Note could only be used for payroll costs (including benefits), interest on mortgage obligations, rent, utilities and interest on certain other debt obligations.

The PPP Note contains customary events of default relating to, among other things, payment defaults, making materially false and misleading representations to the lender or breaching the terms of the PPP Note documents. The occurrence of an event of default could result in an increase in the interest rate to 18% per annum and provides the lender with customary remedies, including the right to require immediate payment of all amounts owed under the PPP Note.

Pursuant to the terms of the CARES Act and the PPP, the Company may apply to the Lender for forgiveness for the amount due on the Loan. The amount eligible for forgiveness is based on the amount of Loan proceeds used by the Company (during the 24-week period after the Lender makes the first disbursement of Loan proceeds) for the payment of certain covered costs, including payroll costs (including benefits), rent and utilities, subject to certain limitations and reductions in accordance with the CARES Act and the PPP.

During January 2021, the Company submitted its application for forgiveness to the Lender. On July 15, 2021, the SBA informed the Company of its full forgiveness for the entire Loan amount plus accrued interest, which was $4.8 million as of June 30, 2021. The SBA’s determination of loan forgiveness does not preclude further investigation by the SBA according to its rules and regulations. See Note 19, Subsequent Events for further detail on the status of the Company’s PPP Loan.

Convertible Notes

NOTE 10. CONVERTIBLE NOTES

On March 27, 2018, the Company issued $150.0 million aggregate principal amount of 2.50% Senior Convertible Notes due 2023. In connection with the offering of the Notes, the Company granted the initial purchasers of the Notes a 13-day option to purchase up to an additional $22.5 million aggregate principal amount of the Notes on the same terms and conditions. On April 4, 2018, the option was partially exercised, which resulted in $21.5 million of additional proceeds, for total proceeds of $171.5 million. The Notes are the Company's senior unsecured obligations and mature on March 15, 2023 (the “Maturity Date”), unless earlier repurchased or converted into shares of common stock under certain circumstances described below. Upon conversion of the Notes, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock, at the Company’s election. The initial conversion rate of the Notes is 32.3428 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $30.92 per share of common stock, subject to adjustment. The Company pays interest on the Notes semi-annually in arrears on March 15 and September 15 of each year.

The $171.5 million of proceeds received from the issuance of the Notes were allocated between long-term debt (the “liability component”) of $116.6 million and contributed capital (the “equity component”) of $54.9 million. The fair value of the liability component was measured using rates determined for similar debt instruments without a conversion feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the aggregate face value of the Notes. The liability component will be accreted up to the face value of the Notes of $171.5 million, which will result in additional non-cash interest expense being recognized through the Maturity Date. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.

The Company incurred approximately $5.0 million of issuance costs related to the issuance of the Notes, of which $3.4 million and $1.6 million were recorded to long-term debt and contributed capital, respectively. The $3.4 million of issuance costs recorded as long-term debt on the condensed consolidated balance sheet are being amortized over the five-year contractual term of the Notes using the effective interest method. The effective interest rate on the Notes, including accretion of the Notes to par and debt issuance cost amortization, is 11.52%.

The Notes include customary terms and covenants, including certain events of default upon which the Notes may be due and payable immediately. Holders have the option to convert the Notes in multiples of $1,000 principal amount at any time prior to December 15, 2022, but only in the following circumstances:

•if the Company’s stock price exceeds 130% of the conversion price for 20 of the last 30 trading days of any calendar quarter after June 30, 2018;

•during the 5 business day period after any 5 consecutive trading day period in which the Notes’ trading price is less than 98% of the product of the common stock price times the conversion rate; or

•the occurrence of certain corporate events, such as a change of control, merger or liquidation.

At any time on or after December 15, 2022, a holder may convert its Notes in multiples of $1,000 principal amount. Holders of the Notes who convert their Notes in connection with a make-whole fundamental change (as defined in the Indenture pursuant to which the Notes were issued) are, under certain circumstances, entitled to an increase in the conversion rate. In addition, in the event of a fundamental change or event of default prior to the Maturity Date, holders will, subject to certain conditions, have the right, at their option, to require the Company to repurchase for cash all or part of the Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest up to, but excluding, the repurchase date.

The Notes at June 30, 2021 and December 31, 2020 consisted of the following (in thousands):

	June 30,		December 31,
	2021		2020
Outstanding principal	$	171,500	$	171,500

As of June 30, 2021 and December 31, 2020, no Notes were convertible pursuant to their terms.

In connection with the Notes issuance, the Company entered into a prepaid forward stock repurchase transaction (“Prepaid Forward”) with a financial institution (“Forward Counterparty”). Pursuant to the Prepaid Forward, the Company used approximately $45.1 million of the net proceeds from its issuance of the Notes to fund the Prepaid Forward. The aggregate number of shares of the Company’s common stock underlying the Prepaid Forward was approximately 1,858,500. The expiration date for the Prepaid Forward is March 15, 2023, although it may be settled earlier in whole or in part. Upon settlement of the Prepaid Forward, at expiration or upon any early settlement, the Forward Counterparty will deliver to the Company the number of shares of common stock underlying the Prepaid Forward or the portion thereof being settled early. The shares purchased under the Prepaid Forward are treated as treasury stock and not outstanding for purposes of the calculation of basic and diluted earnings per share, but will remain outstanding for corporate law purposes, including for purposes of any future stockholders’ votes, until the Forward Counterparty delivers the shares underlying the Prepaid Forward to the Company. The Company’s Prepaid Forward hedge transaction exposes the Company to credit risk to the extent that its counterparty may be unable to meet the terms of the transaction. The Company mitigates this risk by limiting its counterparty to a major financial institution.

NOTE 11. EARNINGS PER SHARE

Basic net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period. Basic and diluted net loss per share are the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive due to the Company’s losses.

The following potentially issuable common shares were not included in the computation of diluted net loss per share because they would have an anti-dilutive effect for each of the three and six months ended June 30, 2021 and 2020 (in thousands):

Potentially dilutive common shares would also include common shares that would be outstanding if Notes convertible at the balance sheet date were converted. As discussed in Note 10, Convertible Notes, the Company issued $171.5 million of Notes due 2023. Upon conversion of the Notes, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock, at the Company’s election. The initial conversion rate of the Notes is 32.3428 shares of common stock per $1,000 principal amount of the Notes. As of June 30, 2021, no Notes were convertible pursuant to their terms. The number of shares issuable upon conversion of the Notes is 5.5 million shares.

In connection with the Notes, the Company entered into a prepaid forward stock repurchase transaction. The aggregate number of shares of the Company’s common stock underlying the Prepaid Forward was approximately 1,858,500. The shares purchased under the Prepaid Forward are treated as treasury stock and not outstanding for purposes of the calculation of basic and diluted earnings per share, but will remain outstanding for corporate law purposes, including for purposes of any future stockholders’ votes, until the Forward Counterparty delivers the shares underlying the Prepaid Forward to the Company.

As discussed in Note 17, Stockholders’ Equity, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain Purchasers (as defined in Note 17, Stockholders’ Equity) for the issuance and sale by the Company of an aggregate of 4,166,663 shares of the Company’s common stock. The agreement contemplates that the closing of the purchase and sale of the shares will occur in three approximately equal tranches on the dates as specified in the agreement or such other dates as the parties may agree, with the first and second tranches having closed on February 19, 2021, and April 9, 2021, respectively. Shares from the third tranche were not included in the computation of diluted net loss per share because they would have an anti-dilutive effect due to net losses.

As of June 30, 2021, unrecognized equity-based compensation expense related to unvested stock options and unvested RSUs was $9.4 million and $19.2 million, respectively. This is expected to be recognized over the years 2021 through 2026.

Included in the above-noted stock options outstanding and stock compensation expense are performance-based stock options which vest only upon the achievement of certain targets. Performance-based stock options are generally granted at-the-money, contingently vest over a period of 1 to 2 years, depending on the nature of the performance goal, and have contractual lives of 10 years. These options were valued in the same manner as the time-based options, with the assumption that performance goals will be achieved. The inputs for expected volatility, expected dividends, and risk-free rate used in estimating those options’ fair value are the same as the time-based options issued under the Company's 2012 Omnibus Equity Incentive Plan. The expected term for performance-based stock options is 5 to 7 years. However, the Company only recognizes stock compensation expense to the extent that the targets are determined to be probable of being achieved, which triggers the vesting of the performance options.

In 2020, the Company granted 105,000 performance-based stock options. 45,000 performance-based stock options vested in prior periods due to the performance obligations being achieved. During the six months ended June 30, 2021, another 45,000 performance-based stock options vested due to the performance obligations being achieved. None of these options have been forfeited as of June 30, 2021.

The table below summarizes share-based compensation cost in connection with performance-based stock options for the six months ended June 30, 2021 and 2020 (in thousands):

	Six Months Ended June 30,
	2021		2020
Performance-based stock option expense	$	230	$	—

Included in the above-noted RSU and performance-based award outstanding amounts are performance-based RSUs which vest only upon the achievement of certain targets. Performance-based RSUs contingently vest over a period of 1 to 3 years, depending on the nature of the performance goal, and have contractual lives of 10 years. These units were valued in the same manner as other RSUs, based on the published closing market price on the day before the grant date. However, the Company only recognizes stock compensation expense to the extent that the targets are determined to be probable of being achieved, which triggers the vesting of the performance options.

In 2020, the Company granted 364,338 performance-based RSUs. 81,000 performance-based RSUs were released in prior periods due to the performance obligations being achieved. 33,364 of these performance-based RSUs were forfeited due to the employees separating from the Company, of which 9,369 were forfeited during the six months ended June 30, 2021. During the six months ended June 30, 2021, 84,000 of these performance-based RSUs were released due to the performance obligations being achieved. At June 30, 2021 165,974 of these performance-based RSUs were outstanding. None of these performance-based RSUs have been forfeited due to performance obligations not being achieved.

In 2021, the Company granted 233,472 performance-based RSUs. During the six months ended June 30, 2021, 3,255 of these performance-based RSUs were forfeited due to the employees separating from the Company. None of these performance-based RSU's have been released. At June 30, 2021 230,217 of these performance-based RSUs were outstanding. None of these performance-based RSUs have been forfeited due to performance obligations not being achieved.

Income Tax Disclosure [Abstract]

Income Taxes

NOTE 13. INCOME TAXES

For the six months ended June 30, 2021, the Company did not carry an income tax provision amount as the Company does not recognize tax benefits from current year tax losses in the U.S. and other foreign jurisdictions. The Company’s tax expense for the six months ended June 30, 2021 differs from the tax expense computed by applying the U.S. statutory tax rate to its year-to-date pre-tax loss of $45.9 million, as no tax benefits were recorded for tax losses generated in the U.S. and other foreign jurisdictions due to the valuation allowance. At June 30, 2021, the Company had deferred tax assets primarily related to U.S. federal and state tax loss carryforwards and a deferred tax liability related to amortization of the Notes. The Company provided a valuation allowance against its net deferred tax assets as future realization of such assets is not more likely than not to occur.

The Company accounts for uncertain tax positions pursuant to the recognition and measurement criteria under ASC 740, Income Taxes. For the three and six months ended June 30, 2021, we did not note any significant changes to our uncertain tax positions. We do not anticipate significant changes to uncertain tax positions within the next 12 months.

In December 2019, the FASB issued ASU No. 2019-12 Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. See Note 2, Recently Issued Accounting Pronouncements for additional information.

In the first quarter of 2021, the Company was informed by the IRS that they would begin an examination of the Company’s 2018 tax year. Due to the early stage of the examination, management is unable to determine the impact the examination will have on the Company's tax position.

NOTE 17. STOCKHOLDERS’ EQUITY

Equity Sales Agreement

On May 28, 2021, the Company entered into an Equity Sales Agreement (the “Sales Agreement”) with William Blair & Company, L.L.C. (“William Blair”) pursuant to which it may sell shares of the Company’s common stock having an aggregate offering price of up to $50 million, from time to time, through an “at-the-market” equity offering program under which William Blair will act as sales agent. Subject to the terms and conditions of the Sales Agreement, William Blair may sell shares by any method deemed to be an “at-the-market” offering as defined in Rule 415 under the U.S. Securities Act of 1933, as amended (the “Securities Act"). The Company is not obligated to sell any shares under the Sales Agreement. William Blair is entitled to a commission of 3% of the aggregate gross proceeds from each sale of shares occurring pursuant to the Sales Agreement. During the three months ended June 30, 2021, the Company sold 92,497 shares of common stock under the Sales Agreement at a price per share of $8.80 resulting in aggregate gross proceeds of $0.8 million, which was recorded to contributed capital.

Securities Purchase Agreement

On December 24, 2020, the Company entered into the Securities Purchase Agreement with Jack W. Schuler, John Patience, Matthew Strobeck, Mark C. Miller, Thomas D. Brown and Jack Phillips, or entities affiliated with such persons (collectively, the “Purchasers”), for the issuance and sale by the Company of an aggregate of 4,166,663 shares of the Company’s common stock (the “Shares”), to the Purchasers in an offering exempt from registration pursuant to Section 4(a)(2) of the Securities Act, and Rule 506 promulgated thereunder. Each of Jack W. Schuler, John Patience, Matthew Strobeck, Mark C. Miller, Thomas D. Brown and Jack Phillips is a member of the Company’s board of directors. Mr. Phillips also serves as the Company’s President and Chief Executive Officer. The entity affiliated with Jack W. Schuler that originally entered into the Securities Purchase Agreement subsequently entered into an assignment and assumption agreement whereby it assigned all of its rights and obligations as a Purchaser to three other entities that became Purchasers under the Securities Purchase Agreement. These three entities are related to Jack W. Schuler but are not affiliates of his.

Pursuant to the Securities Purchase Agreement, the Purchasers have agreed to purchase the Shares at a purchase price (determined in accordance with Nasdaq rules relating to the “market value” of the Company’s common stock) of $7.68 per share, which is equal to the consolidated closing bid price reported by Nasdaq immediately preceding the time the Company entered into the Securities Purchase Agreement for an aggregate purchase price of approximately $32 million. The Securities Purchase Agreement contemplates that the closing of the purchase and sale of the Shares will occur in three approximately equal tranches on the dates specified in the agreement or such other dates as the parties may agree, with the first and second tranches having closed on February 19, 2021 and April 9, 2021, respectively. Proceeds from the closings of the first and second tranches under the Securities Purchase Agreement were recorded to contributed capital of $10.7 million and $21.3 million for the three and six months ended June 30, 2021, respectively.

Subsequent Events

NOTE 19. SUBSEQUENT EVENTS

The Company evaluates events that have occurred after the balance sheet date but before the financial statements are issued. Pursuant to the terms of the CARES Act and the PPP, the Company may apply to the Lender for forgiveness for the amount due on the Loan. The amount eligible for forgiveness is based on the amount of Loan proceeds used by the Company (during the 24-week period after the Lender makes the first disbursement of Loan proceeds) for the payment of certain covered costs, including payroll costs (including benefits), rent and utilities, subject to certain limitations and reductions in accordance with the CARES Act and the PPP.

During January 2021, the Company submitted its application for forgiveness to the Lender. On July 15, 2021, the SBA informed the Company of its full forgiveness for the entire Loan amount plus accrued interest, which was $4.8 million as of June 30, 2021. The SBA’s determination of loan forgiveness does not preclude further investigation by the SBA according to its rules and regulations.

With approval of the Company's application for forgiveness the Company will record income from the extinguishment as a gain recorded to other income (expense), net in the third quarter of 2021. See Note 9, Long-Term Debt for further detail on the Company’s PPP Loan.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as filed with the SEC on March 2, 2021.

The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited financial statements as of that date but does not include all disclosures such as notes required by U.S. GAAP.

The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the entire year ending December 31, 2021, or any future period.

All amounts are rounded to the nearest thousand dollars unless otherwise indicated.

Principles of Consolidation

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after elimination of intercompany transactions and balances.

Use of Estimates

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to accounts receivable, inventory, property and equipment, accrued liabilities, warranty liabilities, tax valuation accounts, equity–based compensation, revenue and leases. Actual results could differ materially from those estimates.

Estimated Fair Value of Financial Instruments

Estimated Fair Value of Financial Instruments

The Company follows Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, which has defined fair value and requires the Company to establish a framework for measuring and disclosing fair value. The framework requires the valuation of assets and liabilities subject to fair value measurements using a three-tiered approach and fair value measurement to be classified and disclosed in one of the following three categories:

•Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

•Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;

•Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).

The carrying amounts of financial instruments such as cash and cash equivalents, trade accounts receivable, prepaid expenses, other current assets, accounts payable, accrued liabilities, and other current liabilities approximate the related fair values due to the short-term maturities of these instruments.

The estimated fair value of the Company’s convertible note represents a Level 2 measurement.

Cash and Cash Equivalents

Cash and Cash Equivalents

All highly liquid investments with an original maturity of three months or less at time of purchase are considered to be cash equivalents. Cash and cash equivalents include overnight repurchase agreement accounts and other investments. As part of our cash management process, excess operating cash is invested in overnight repurchase agreements with our bank. Repurchase agreements and other investments classified as cash and cash equivalents are not deposits and are not insured by the U.S. Government, the FDIC or any other government agency and involve investment risk including possible loss of principal. We believe, however, that the market risk arising from holding these financial instruments is minimal.

Investments

Investments

The Company invests in various debt and equity securities which are primarily held in the custody of major financial institutions. Debt securities consist of certificates of deposit, U.S. government and agency securities, commercial paper, and corporate notes and bonds. Equity securities consist of mutual funds. The Company records these investments in the condensed consolidated balance sheet at fair value. Unrealized gains or losses for debt securities available-for-sale are included in accumulated other comprehensive income, a component of stockholders’ deficit. Unrealized gains or losses for equity securities are included in other income (expense), net. The Company considers all debt securities available-for-sale, including those with maturity dates beyond 12 months, as available to support current operational liquidity needs. The Company classifies its investments as current based on the nature of the investments and their availability for use in current operations.

We perform an assessment to determine whether there have been any events or economic circumstances to indicate that a debt security available-for-sale in an unrealized loss position has suffered impairment as a result of credit loss or other factors. A debt security is considered impaired if its fair value is less than its amortized cost basis at the reporting date.

If we intend to sell the debt security or if it is more-likely-than-not that we will be required to sell the debt security before the recovery of its amortized cost basis, the impairment is recognized and the unrealized loss is recorded as a direct write-down of the security's amortized cost basis with an offsetting entry to earnings. If we do not intend to sell the debt security or believe we will not be required to sell the debt security before the recovery of its amortized cost basis, the impairment is assessed to determine if a credit loss component exists. We use a discounted cash flow method to determine the credit loss component. In the event a credit loss exists, an allowance for credit losses is recorded in earnings for the credit loss component of the impairment while the remaining portion of the impairment attributable to factors other than credit loss is recognized, net of tax, in accumulated other comprehensive income. The amount of impairment recognized due to credit factors is limited to the excess of the amortized cost basis over the fair value of the security.

Inventory

Inventory

Inventory is stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first out method. The Company estimates the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. The Company periodically analyzes its inventory levels to identify inventory that may expire prior to expected sale or has a cost basis in excess of its estimated realizable value and records a charge to expense for such inventory as appropriate.

Accounts Receivable

Accounts Receivable

Accounts receivable consist of amounts due to the Company for sales to customers and are based on what we expect to collect in exchange for goods and services. Receivables are considered past due based on the contractual payment terms and are written off if reasonable collection efforts prove unsuccessful.

We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the condensed consolidated statements of operations. We assess collectibility by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when we identify specific customers with known disputes or collectibility issues. In determining the amount of the allowance for credit losses, we consider historical collectibility and make judgments about the creditworthiness of customers based on credit evaluations. Our customers typically have good credit quality. We also consider customer-specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data.

Property and Equipment

Property and Equipment

Property and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred and expenditures for major improvements are capitalized. Gains and losses from retirement or replacement are included in costs and expenses. Depreciation of property and equipment is computed using the straight-line method over the estimated useful life of the assets, ranging from one to seven years. Leasehold improvements are depreciated over the remaining life of the lease or the life of the asset, whichever is less.

Instruments Classified as Property and Equipment

Property and equipment includes Accelerate Pheno systems (also referred to as instruments) used for sales demonstrations, instruments under rental agreements and instruments used for research and development. Depreciation expense for instruments used for sales demonstrations is recorded as a component of sales, general and administrative expense. Depreciation expense for instruments placed at customer sites pursuant to reagent

rental agreements is recorded as a component of cost of sales. Depreciation expense for instruments used in our laboratory and research is recorded as a component of research and development expense. The Company retains title to these instruments and depreciates them over five years. Losses from the retirement of returned instruments are included in costs and expenses.

The Company evaluates the recoverability of the carrying amount of its instruments whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, and this evaluation is performed at least annually. This evaluation is based on our estimate of future cash flows and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of instruments. No impairment charges have been recorded as of June 30, 2021 and December 31, 2020.

Long-lived Assets

Long-lived Assets

Long-lived assets and certain identifiable intangibles to be held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company continuously evaluates the recoverability of its long-lived assets based on estimated future cash flows from and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of the long-lived asset.

Warranty Reserve

Warranty Reserve

Instruments are typically sold with a one year limited warranty, while kits and accessories are typically sold with a sixty days limited warranty. Accordingly, a provision for the estimated cost of the limited warranty repair is recorded at the time revenue is recognized. Our estimated warranty provision is based on our estimate of future repair events and the related estimated cost of repairs. The Company periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary. The expense incurred for these provisions is included in cost of sales on the condensed consolidated statements of operations and comprehensive loss.

Convertible Notes

Convertible Notes

The Company accounts for convertible debt instruments that may be settled in cash or equity upon conversion, which includes the 2.50% Senior Convertible Notes due 2023 (the “Notes”), by separating the liability and equity components of the instruments in a manner that reflects our nonconvertible debt borrowing rate. The Company determined the carrying amount of the liability component of the Notes by using estimates and assumptions that market participants would use in pricing a debt instrument. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component, and the associated non-cash interest expense.

The equity component is treated as a discount on the liability component of the Notes, which is amortized over the term of the Notes using the effective interest rate method. Debt issuance costs related to the Notes are allocated to the liability and equity components of the Notes based on their relative values. Debt issuance costs allocated to the liability component are amortized over the life of the Notes as additional non-cash interest expense. Transaction costs allocated to equity are netted with the equity component of the convertible debt instrument in stockholders’ deficit.

Revenue Recognition

Revenue Recognition

The Company recognizes revenue when control of the promised good or service is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Sales taxes are excluded from revenues.

The Company determines revenue recognition through the following steps:

•Identification of the contract with a customer

•Identification of the performance obligations in the contract

•Determination of the transaction price

•Allocation of the transaction price to the performance obligations

•Recognition of revenue as we satisfy a performance obligation

Product revenue is derived from the sale or rental of our instruments and sales of related consumable products. When an instrument is sold, revenue is generally recognized upon installation of the unit consistent with contract terms, which do not include a right of return. When a consumable product is sold, revenue is generally recognized upon shipment. Invoices are generally issued when revenue is recognized and the term between invoicing and when payment is due is not typically significant.

Service revenue is derived from the sale of extended service agreements which are generally non-cancellable. This revenue is recognized on a straight-line basis over the contract term beginning on the effective date of the contract because the Company is standing ready to provide services. Invoices are generally issued annually and coincide with the beginning of individual service terms.

Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine relative standalone selling prices based on the price charged to customers for each individual performance obligation.

Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The Company has determined these costs would have an amortization period of less than one year and has elected to recognize them as an expense when incurred. Contract asset opening and closing balances were immaterial for the three and six months ended June 30, 2021.

Cost of Sales

Cost of sales includes cost of materials, direct labor, equity-based compensation, facility and other manufacturing overhead costs for consumable tests and instruments sold to customers. Cost of sales for instruments also includes depreciation on revenue generating instruments that have been placed with our customers under a reagent rental agreement. Cost of sales includes repair and maintenance cost for instruments covered by a service agreement or instruments covered by a reagent rental agreement. Cost of sales also includes warranty related expenses.

Shipping and Handling

Shipping and handling costs billed to customers are included as a component of revenue. The corresponding expense incurred with third party carriers is included as a component of sales, general and administrative costs on the condensed consolidated statements of operations and comprehensive loss.

Leases, Lessee

Leases

The Company accounts for commercial leases in accordance with ASC 842, Leases. We determine if an arrangement is or contains a lease and the type of lease at inception. The Company classifies commercial leases as finance leases (lessee) or sales-type leases (lessor) when there is either a transfer of ownership of the underlying asset by the end of the lease term, the lease contains an option to purchase the asset that we are reasonably certain will be exercised, the lease term is for the major part of the remaining economic life of the asset, the present value of the lease payments and any residual value guarantee equals or substantially exceeds all the fair value of the asset, or the asset is of such a specialized nature that it will have no alternative use to the lessor at the end of the lease term. Payments contingent on future events (i.e. based on usage) are considered variable and excluded from lease payments for the purposes of classification and initial measurement. Several of our leases include options to renew or extend the term upon mutual agreement of the parties and others include one-year extensions exercisable by the lessee. None of our leases contain residual value guarantees, restrictions, or covenants.

To determine whether a contract contains a lease, the Company uses its judgment in assessing whether the lessor retains a material amount of economic benefit from an underlying asset, whether explicitly or implicitly identified, which party holds control over the direction and use of the asset, and whether any substantive substitution rights over the asset exist.

Lessee

Operating leases are included in right-of-use (“ROU”) assets and operating lease liabilities within our consolidated balance sheets. These assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and their related liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Typically, we use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments. We use the implicit rate when readily determinable. ROU assets are net of lease payments made and exclude lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term, which may include options to extend or terminate the lease when it is reasonably certain that we will exercise the option. As of June 30, 2021 and December 31, 2020, the Company was not a party to finance lease arrangements.

Our operating leases consist primarily of leased office, factory, and laboratory space in the U.S. and office space in Europe, have between two and six-year terms, and typically contain penalizing, early-termination provisions.

Lessor

The Company leases instruments to customers under “reagent rental” agreements, whereby the customer agrees to purchase consumable products over a stated term, typically five years or less, for a volume-based price that includes an embedded rental for the instruments. When collectibility is probable, that amount is recognized as income at lease commencement for sales-type leases and as product is shipped, typically in a straight–line pattern, over the term for operating leases, which typically include a termination without cause or penalty provision given a short notice period.

Consideration is allocated between lease and non-lease components based on stand-alone selling price in accordance with ASC 606, Revenue from Contracts with Customers.

Net investment in sales-type leases are included within our condensed consolidated balance sheets as a component of other current assets and other non-current assets, which include the present value of lease payments not yet received and the present value of the residual asset, which are determined using the information available at commencement, including the lease term, estimated useful life, rate implicit in the lease, and expected fair value of the instrument.

Nonqualified Cash Deferral Plan

Nonqualified Cash Deferral Plan

The Company's Cash Deferral Plan (the “Deferral Plan”), provides certain key employees, with an opportunity to defer the receipt of such participant's base salary. The Deferral Plan is intended to be a nonqualified deferred compensation plan that complies with the provisions of Section 409A of the Internal Revenue Code. All of the investments held in the Deferral Plan are equity securities consisting of mutual funds and recorded at fair value with changes in the investments' fair value recognized as earnings in the period they occur. The corresponding liability for the Deferral Plan is included in other non-current liabilities in the condensed consolidated balance sheet.

Equity-Based Compensation

Equity-Based Compensation

The Company may award stock options, restricted stock units (“RSUs”), performance-based awards, and other equity-based instruments to its employees, directors and consultants. Compensation cost related to equity-based instruments is based on the fair value of the instrument on the grant date, and is recognized over the requisite service period on a straight-line basis over the vesting period for each tranche (an accelerated attribution method) except for performance-based awards. Performance-based awards vest based on the achievement of performance targets. Compensation costs associated with performance-based awards are recognized over the requisite service period based on probability of achievement. Performance-based awards require management to make assumptions regarding the likelihood of achieving performance targets.

The Company estimates the fair value of service based and performance based stock option awards, including modifications of stock option awards, using the Black-Scholes option pricing model. This model derives the fair value of stock options based on certain assumptions related to expected stock price volatility, expected option life, risk-free interest rate and dividend yield.

•Volatility: The expected volatility is based on the historical volatility of the Company's stock price over the most recent period commensurate with the expected term of the stock option award.

•Expected term: The estimated expected term for employee awards is based on the calculation published by the SEC in SAB110 for use when there is not a sufficient history of employee exercise patterns. For consultant awards, the estimated expected term is the same as the life of the award.

•Risk-free interest rate: The risk-free interest rate is based on published U.S. Treasury rates for a term commensurate with the expected term.

•Dividend yield: The dividend yield is estimated as zero as the Company has not paid dividends in the past and does not have any plans to pay any dividends in the foreseeable future.

The Company records the fair value of RSUs or stock grants based on published closing market price on the day before the grant date. The Company accounts for forfeitures as they occur rather than on an estimated basis.

Deferred Tax

Deferred Tax

Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying balance sheets. The change in deferred tax assets and liabilities for the period represents the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws in deferred tax assets and liabilities are reflected as an adjustment to the tax provision or benefit in the period of enactment.

The Company follows the provisions of ASC 740, Income Taxes, to account for any uncertainty in income taxes with respect to the accounting for all tax positions taken (or expected to be taken) on any income tax return. This guidance applies to all open tax periods in all tax jurisdictions in which the Company is required to file an income tax return. Under U.S. GAAP, in order to recognize an uncertain tax benefit, the taxpayer must be more likely than not certain of sustaining the position, and the measurement of the benefit is calculated as the largest amount that is more likely than not to be realized upon resolution of the position. Interest and penalties, if any, would be recorded within tax expense.

Foreign Currency Translation and Foreign Currency Transactions

Foreign Currency Translation and Foreign Currency Transactions

Adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars are included in the foreign currency translation adjustment, a component of accumulated other comprehensive income loss.

The Company has assets and liabilities, including receivables and payables, which are denominated in currencies other than their functional currency. These balance sheet items are subject to re-measurement, the impact of which is recorded in foreign currency exchange gain and loss, within the condensed consolidated statement of operations and comprehensive loss.

Loss Per Share

Loss Per Share

Basic loss per share includes no dilution and is computed by dividing loss available to common stockholders by the weighted average number of common shares outstanding for the period. Potentially dilutive common shares consist of shares issuable from stock options and unvested RSUs. Potentially dilutive common shares would also include common shares that would be outstanding if the Notes at the balance sheet date were converted and shares issuable in connection with a securities purchase agreement. Diluted earnings are not presented when the effect of adding such additional common shares is antidilutive.

Comprehensive Loss

Comprehensive Loss

In addition to net loss, comprehensive loss includes all changes in equity during a period, except those resulting from investments by and distributions to owners. The Company holds investments classified as debt securities available-for-sale and records the change in fair market value as a component of comprehensive loss. The Company also has adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars which is included as a component of comprehensive loss.

Standards that were recently adopted and standards not yet adopted

Standards that were recently adopted

In January 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the FASB Emerging Issues Task Force). ASU 2020-01 clarifies the interaction of the accounting for equity securities under Topic 321, the accounting for the equity method investments in Topic 323 and the accounting for certain forward contracts and purchased options in Topic 815. The Company adopted ASU 2020-01 on January 1, 2021, which had no impact to our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740); Simplifying the Accounting for Income Taxes. ASU 2019-12 reduces complexity in the accounting standard. The Company adopted ASU 2019-12 on January 1, 2021, which had no impact to our consolidated financial statements. The Company maintains a full valuation allowance against its net deferred tax assets. The valuation allowance is based on management’s assessment that it is more likely than not that the Company will not have taxable income in the foreseeable future.

Standards not yet adopted

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2020-06 reduces the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. In addressing the complexity, this ASU amends the guidance on convertible instruments and the guidance on the derivatives scope exception for contracts in an entity’s own equity. This ASU will reduce the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP standards. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. This ASU is effective for us on January 1, 2022, with early adoption permitted. We are currently assessing the impact this will have on our consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). ASU 2021-04 will codify the final consensus reached by the Emerging Issues Task Force (EITF) on how an issuer should account for modifications made to equity-classified written call options (hereafter referred to as a warrant to purchase the issuer’s common stock). The guidance in the ASU requires the issuer to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange of the original warrant for a new warrant. This guidance applies whether the modification is structured as an amendment to the terms and conditions of the warrant or as termination of the original warrant and issuance of a new warrant. This ASU is effective for us on January 1, 2022, with early adoption permitted. We are currently assessing the impact this will have on our consolidated financial statements, and believe it will not have an impact on the Company's consolidated financial statements at January 1, 2022.
