The forward-looking statements are contained principally in Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Part II, Item 1A, “Risk Factors,” but are also contained elsewhere in this Quarterly Report. In some cases, you can identify forward-looking statements by the words “may,” “might,” “will,” “would,” “could,” “should,” “intend,” “plan,” “contemplate,” “expect,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “target,” “potential,” “continue,” and “ongoing” and other comparable expressions intended to identify statements about the future, although not all forward-looking statements contain these identifying words. These statements involve substantial known and unknown risks, uncertainties and other factors that may cause our actual results, level of activity, performance or achievements to differ materially from those currently anticipated. Forward-looking statements are neither historical facts nor assurances of future performance. Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report, we caution you that these statements are based on a combination of facts and factors currently known by us and our expectations of the future, about which we cannot be certain and that involve substantial risks and uncertainties. Such risks and uncertainties include, but are not limited to:

● our failure to meet our obligations arising from the sale of our U.S. laboratory services business, or the U.S. Laboratory Services Business, to Quest Diagnostics Incorporated, or Quest, a Delaware corporation, or the Transaction;

● the potential disruption of management time from ongoing business operations due to the Transaction;

● potential changes in the United States, or U.S., social, political, regulatory and economic conditions or laws and policies governing the health care system, U.S. tax laws, foreign trade, immigration, manufacturing, and development and investment in the territories and countries where we or our customers and suppliers operate;

● our ability to make successful acquisitions or investments and to manage the integration of such acquisitions or investments;

Oxford Immunotec Global PLC

Notes to Unaudited Condensed Consolidated Financial Statements

March 31, 2019

1. Business and basis of presentation

Description of business

Oxford Immunotec Global PLC, or the Company, is a global, high-growth diagnostics company focused on developing and commercializing proprietary tests for immunology and infectious disease by leveraging the technological, product development, manufacturing, quality, regulatory, and sales and marketing capabilities it has developed over its seventeen year history. The Company’s proprietary T-SPOT.TB test utilizes its T-SPOT technology platform to test for tuberculosis, which is the leading cause of infectious disease death worldwide.

Discontinued operations

The Company reports the results of operations of a business that either has been disposed of or is classified as held for sale, in accordance with Accounting Standards Codification, or ASC, 360, Property, Plant, and Equipment, in discontinued operations, as required by ASC 205, Presentation of Financial Statements. The Company presents such events as discontinued operations so long as the financial results can be clearly identified and the future operations and cash flows are completely eliminated from ongoing operations. The Company’s historical results for all periods presented are restated to account for businesses reported as discontinued operations in our Consolidated Financial Statements and these Notes. Unless otherwise specified, disclosures in our Consolidated Financial Statements and these Notes relate solely to our continuing operations.

As discussed in Note 13, Discontinued operations, on September 25, 2018, the Company entered into an agreement to sell the Company’s U.S. Laboratory Services Business to Quest Diagnostics Incorporated. The Transaction represents a strategic business shift having a major effect on the Company’s operations and financial results. Accordingly, operations have been reported in discontinued operations in the consolidated financial statements for all periods presented. The Transaction was consummated on November 6, 2018 for gross proceeds of $170 million in cash. Immediately following the Transaction, the Company had approximately 210 employees, including sales and marketing teams on three continents, and a laboratory in the United Kingdom.

Unaudited interim financial statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments, of a normal recurring nature, necessary for a fair statement of the financial position at March 31, 2019, the results of operations for the three-month periods ended March 31, 2019 and 2018, and the cash flows for the three-month periods ended March 31, 2019 and 2018. Interim results are not necessarily indicative of results for a full year.

The consolidated balance sheet presented as of December 31, 2018, has been derived from the audited consolidated financial statements as of that date. The consolidated financial statements and notes included in this report should be read in conjunction with the 2018 consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on March 28, 2019, or the Company’s 2018 Form 10-K.

Cash, cash equivalents, and restricted cash

The Company considers all highly liquid investments purchased with maturities at acquisition of three months or less to be cash equivalents. The Company maintains its available cash balances in cash, money market funds and repurchase agreements primarily invested in U.S. government and agency securities, and bank savings accounts in the United States, United Kingdom, Germany, Japan, China and South Korea. The Company maintains deposits in government insured financial institutions in excess of government insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

Restricted cash relates to collateral for procurement cards issued by a U.S. commercial bank.

Cash, cash equivalents, and restricted cash consists of the following:

(in thousands)	March 31, 2019		December 31, 2018
Cash and cash equivalents	$	189,518	$	192,844
Restricted cash, non-current		100		100
Total cash, cash equivalents, and restricted cash	$	189,618	$	192,944

Revenues

The Company’s revenues include product and service revenues. In general, revenue from diagnostic test kit sales and related accessories is recognized at a point in time based upon contractual rates. However, for contracts with tiered pricing provisions, if the tiered pricing constitutes a material right and spans across multiple reporting periods, the Company estimates the total transaction price at the beginning of each reset period (i.e. the period in which revenue at different tiers is earned and settled) based on expected volumes. The Company revises its estimates of variable consideration at each reporting date throughout each reset period. Service revenue is recorded based upon contractually established billing rates and recognized upon delivery of test results to the customer. See Note 2. Revenue for disaggregation of revenue by type and geography.

As of March 31, 2019, accounts receivables related to products and services were $10.2 million. For the three months ended March 31, 2019, the Company had no material bad-debt expense and there were no material contract assets, contract liabilities or deferred contract costs recorded on the Condensed Consolidated Balance Sheet as of March 31, 2019. The Company generally expenses sales commissions when incurred because the amortization period would be less than one year.

Revenue expected to be recognized in any future year related to remaining performance obligations is not material.

Taxes assessed by governmental authorities on revenue, including sales and value added taxes, are recorded on a net basis (excluded from revenue) in the consolidated statements of operations.

Other than the following discussion regarding leases, the remainder of the significant accounting estimates and policies used in preparation of the condensed consolidated financial statements disclosed in Note 1. Description of business and significant accounting policies to the consolidated financial statements in the Company’s 2018 Form 10-K remain unchanged.

Leases

In February 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update or ASU 2016-02, Leases, or ASU 2016-02, to enhance the transparency and comparability of financial reporting related to leasing arrangements. The Company adopted ASU 2016-02 on January 1, 2019, or the effective date, and used the effective date as its date of initial application.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Most leases with a term greater than one year are recognized on the balance sheet as right-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected not to recognize on the balance sheet leases with terms of one year or less. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining lease term. The operating lease right-of-use assets also include any lease payments made prior to the commencement date and exclude lease incentives and initial direct costs incurred. The operating lease right-of-use assets are subsequently assessed for impairment in accordance with the Company’s accounting policy for long-lived assets. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rates, which are the rates incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The incremental borrowing rate was determined at lease commencement, or as of January 1, 2019 for operating leases existing upon adoption of ASC 842. The incremental borrowing rate is subsequently reassessed upon modification to the lease arrangement.

In accordance with the guidance in ASU 2016-02, components of a lease should be split into three categories: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, maintenance, consumables, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed and in-substance fixed contract consideration (including any related to non-components) must be allocated based on fair values to the lease components and non-lease components.

Although separation of lease and non-lease components is required, certain practical expedients are available. Entities may elect the practical expedient to not separate lease and non-lease components and would instead account for each lease component and the related non-lease component together as a single component. The Company has elected to account for the lease and non-lease components of each of its operating leases as a single lease component and allocate all of the contract consideration to the lease component only. The lease component results in an operating lease right-of-use asset being recorded on the balance sheet and amortized on a straight-line basis as lease expense.

10

Recently Adopted Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, which requires lessees to reflect all leases with terms longer than 12 months on their balance sheets. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The FASB has subsequently issued amendments to the guidance, including the addition of an optional transition method. The Company’s process of evaluating the impact of ASU 2016-02 has included reviewing all forms of leases and performing a completeness assessment over the lease population. The Company adopted ASU 2016-02 on January 1, 2019 and applied the modified retrospective approach, which recognize a cumulative-effect adjustment, if any, to the opening balance of retained earnings. The Company took advantage of the transition package of practical expedients permitted within ASU 2016-02, which among other things, allowed it to carryforward historical lease classifications. The Company made an accounting policy election that will keep leases with an initial term of 12 months or less and that do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise off of the balance sheet and will result in recognizing those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. As a result of adopting ASU 2016-02, the Company recognized right-of-use assets of about $7.2 million and corresponding liabilities of about $8.2 million for its existing lease portfolio on its consolidated balance sheets. The adoption of ASU 2016-02 has not had a material impact on the Company’s consolidated statements of operations or consolidated statements of cash flows. The Company has included additional disclosures in Note 12. Lease commitments to its condensed consolidated financial statements regarding its leasing portfolio, including key judgments and assumptions and the discount rates used in calculating the Company’s right-of-use assets and corresponding liabilities.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, or ASU 2018-07. ASU 2018-07 simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The Company adopted ASU 2018-07 prospectively as of January 1, 2019. The adoption of ASU 2018-07 has not had a material impact on the Company’s financial position, results of operations or related disclosures.

Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses, or ASU 2016-13. ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. Under current U.S. GAAP, a company only considered past events and current conditions in measuring an incurred loss. Under ASU 2016-13, the information that a company must consider is broadened in developing an expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. The new guidance will be effective for the Company for annual and interim periods beginning after December 15, 2019. Early adoption is permitted for annual and interim periods beginning after December 15, 2018. The guidance is applied using a modified retrospective, or prospective approach, depending on a specific amendment. The Company does not expect that the application of ASU 2016-13 will have a material impact on the presentation of its results of operations, financial position, or related disclosures.

In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other, or ASU 2017-04. ASU 2017-04 simplifies subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The new guidance will be applied on a prospective basis. ASU 2017-04 will be effective for the Company for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests. The Company is currently evaluating ASU 2017-04.

2. Revenue

On November 6, 2018, the Company completed the sale of its U.S. Laboratory Services Business to Quest Diagnostics Incorporated. Accordingly, the Company’s prior year revenues have been recast to present the U.S. laboratory services business as a discontinued operation. For further information on these changes, refer to Note 13, Discontinued operations.

The following tables present the Company’s revenues disaggregated by type:

	Three months ended March 31,
(in thousands)	2019		2018
Revenue
Product	$	13,841	$	10,129
Service		948		1,550
Total revenue	$	14,789	$	11,679

United States	$	5,531	$	3,698
Europe and ROW		2,762		2,236
Asia		6,496		5,745
Total revenue	$	14,789	$	11,679

3. Fair value measurement

As a basis for determining the fair value of certain of the Company’s financial instruments, the Company utilizes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1—Observable inputs such as quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs, other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The carrying amount of certain of the Company’s financial instruments, including cash, accounts receivable, prepaid expenses and other assets, accounts payable, and accrued liabilities approximate fair value due to their short term nature.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the entire fair value measurement requires management to make judgments and consider factors specific to the asset or liability.

The Company had a term loan outstanding under an agreement with MidCap Financial Trust, or MidCap, at March 31, 2018. The amount outstanding on the term loan was reported at its carrying value in the accompanying balance sheet at that date. The estimated fair value of the term loan, based upon market rates at the time for similar borrowings, as measured using Level 2 inputs, approximated the carrying amount as presented on the consolidated balance sheets. In connection with the sale of the U.S. Laboratory Services Business to Quest on November 6, 2018, approximately $32.3 million of the gross proceeds received pursuant to the Transaction, was paid directly to MidCap to repay the outstanding indebtedness under an agreement with MidCap Financial Trust, or the MidCap Agreement, which included prepayment and exit fees of approximately $2.3 million (see Note 8. Loans payable).

6. Goodwill and acquired intangible assets

The Company has one reporting unit and goodwill represents the synergies realized in its acquisitions of Imugen, Inc. and Immunetics, Inc. In conjunction with the Transaction (see Note 13. Discontinued operations) and pursuant to Accounting Standards Codification Topic 350, Intangibles – Goodwill and Other, or ASC 350-20-35-51, the Company allocated a portion of the goodwill to the business being disposed of based on the relative fair value method. As a result, goodwill of $1.5 million was allocated to assets held for sale in the third quarter of 2018, the period that the held for sale election was determined. The carrying amount of goodwill reflected in the Company’s consolidated balance sheets was $2.5 million at March 31, 2019 and December 31, 2018. 

Acquired intangible assets consisted of the following as of March 31, 2019 and December 31, 2018:

Other accrued liabilities		1,210		1,522
Total accrued liabilities	$	9,377	$	10,891

8. Loans payable

On October 4, 2016, the Company entered into an agreement with MidCap Financial Trust, or the MidCap Agreement, that provided it with $40 million in debt financing, comprised of both a term loan and a revolving line of credit. The MidCap Agreement provided the Company with a term loan of $30 million, which matured five years from closing. The term loan accrued interest at a rate of LIBOR plus 7.60% with interest only payments for the first 24 months, with the ability to extend to 48 months subject to certain conditions, before the loan began to amortize. The MidCap Agreement also provided the Company with a revolving line of credit of up to $10 million, which matured five years from closing. The revolving line of credit accrued interest at a rate of LIBOR plus 4.45%. The Company was also required to pay the lenders an unused line fee equal to 0.50% per annum of the average unused portion of the revolving line of credit. Based on certain conditions, both the term loan and revolving line of credit could have been increased by an additional $10 million for a total of $60 million.

In connection with the sale of the U.S. Laboratory Services Business to Quest pursuant to a Limited Liability Company Interest Purchase Agreement on November 6, 2018, approximately $32.3 million of the gross proceeds received pursuant to the Transaction was paid directly to MidCap to repay the outstanding indebtedness under the MidCap Agreement, which included prepayment and exit fees of approximately $2.3 million. In connection with the Company’s repayment of the outstanding indebtedness under the MidCap Agreement, the Term Loan and the Revolving Loan, and all related agreements thereunder, were terminated and all borrowings outstanding thereunder were repaid in full. The repayment resulted in a loss on extinguishment of debt of $2.1 million, which represents the cash paid to settle the debt in excess of debt related balances at the time of settlement. As of March 31, 2018, the Company had a balance of the secured term loan due to MidCap of $30 million, which is recorded in the accompanying consolidated balance sheet at that date, net of unamortized discount and debt issuance costs. The Company never borrowed under the revolving line of credit.

9. Share capital

During the three-month period ended March 31, 2019, the Company issued 141,246 ordinary shares upon the exercise of options and 42,477 ordinary shares were issued upon the vesting of restricted share units, or RSUs. During the twelve months ended December 31, 2018, the Company issued 694,322 ordinary shares upon the exercise of options and 83,378 ordinary shares were issued upon the vesting of RSUs.

10. Share option and equity incentive plan

The impact on the Company’s results of operations from share-based compensation was as follows:

	Three months ended March 31,
(in thousands)	2019			2018
Cost of revenue	$	4		$	66
Research and development		(18	)		218
Sales and marketing		224			567
General and administrative		635			909
Total continuing operations		845			1,760
Discontinued operations		—			64
Total share-based compensation	$	845		$	1,824

In November 2013, in connection with the Company’s initial public offering, the Company adopted the 2013 Share Incentive Plan or the 2013 Plan, which provides for the grant of share options, restricted shares, RSUs, and other share-based awards to employees, officers, directors and consultants of the Company. The 2013 Plan was amended at the 2017 annual general meeting of shareholders.

During the three-month period ended March 31, 2019, the Company granted 5,000 share options with an exercise price of $14.59 per share under the 2013 Plan. The weighted-average grant date fair value related to share options granted under the 2013 Plan during the three-month period ended March 31, 2019 was $6.77 per share. Share options generally vest based on the grantee’s continued service with the Company during a specified period following the vesting start date and expire after ten years.

During the three-month period ended March 31, 2019, the Company did not award any RSUs. RSUs vest based on the grantee’s continued service with the Company during a specified period following grant as follows: 40% on the second anniversary of the vesting start date; 30% on the third anniversary of the vesting start date; and 30% on the fourth anniversary of the vesting start date. Share-based compensation expense for these RSUs is calculated based on the grant date market price of the shares and is being recognized over the vesting period.

For the three month-period ended March 31, 2019, the Company incurred shared-based compensation expense related to share options and RSUs of $649,000 and $196,000, respectively. For the three-month period ended March 31, 2018, the Company incurred shared-based compensation expense related to share options and restricted shares/RSUs of $985,000 and $839,000, respectively.

As of March 31, 2019, there was $4.1 million and $2.4 million of total unrecognized compensation cost related to unvested share options and RSUs, respectively. These costs are expected to be recognized over weighted-average periods of 2 years for option shares and 2 years for RSUs.

11. Net loss per share

The following numbers of outstanding ordinary share options and unvested restricted shares and unvested RSUs were excluded from the computation of diluted net loss per share for the periods presented because their effect would have been anti-dilutive:

	Three months ended March 31,
	2019		2018
Options to purchase ordinary shares		306,951		508,618
Unvested RSUs		62,263		405,527

12. Lease commitments

The Company has operating leases for real estate and non-real estate in the United States, United Kingdom, China, Japan, and Korea. One such operating lease is a sublease for real estate. The Company does not have any material finance leases.

The Company leases office, storage/warehouse, laboratory and manufacturing space in Abingdon, U.K., which leases are due to expire at various dates from June 11, 2019 to June 18, 2033. On March 1, 2013, the Company signed a five year lease for its U.S. corporate headquarters in Marlborough, Massachusetts. In August 2015, the Company entered into a lease amendment for this location to extend the term of the lease by two years through October 31, 2020. In addition, the lease amendment expanded the Company’s office space at this location by 7,600 square feet to a new total of 22,100 square feet. The base rent for the combined space over the lease term will range from an initial low of $36,000 per month, which includes $12,000 per month for the expansion space commencing in early 2016, to a high of $39,000 per month. The Company will have an option to extend the lease for one additional term of five years.

In connection with the sale of our U.S. Laboratory Services Business to Quest, we entered into a sublease with Quest for approximately 9,000 square feet of warehousing and office space in Norwood, Massachusetts. The sublease expires in November 2020. The base rent for the space subject to sublease is approximately $17,000 per month.

In June 2018, the Company entered into a lease for new space in Abingdon, England, which extends through June 2033 that will allow it to combine its manufacturing, laboratory, storage and office operations into a single facility. The base rent on the facility over the lease term will range from $39,000 per month to $79,000 per month. With the exception of manufacturing and associated groups, our U.K. operations are now located in this facility.

Many of the Company’s leases contain options to renew and extend lease terms and options to terminate leases early. Reflected in the right-of-use asset and lease liability on the Company’s balance sheet are the periods provided by renewal and extension options that the Company is reasonably certain to exercise, as well as the periods provided by termination options that the Company is reasonably certain to not exercise.

The Company has existing leases that include variable lease and non-lease components that are not included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. Such payments primarily include common area maintenance charges and increases in rent payments that are driven by factors such as future changes in an index (e.g., the Consumer Price Index).

In calculating the present value of future lease payments, the Company has elected to utilize its incremental borrowing rate based on the remaining lease term at the date of adoption. The Company has elected to account for each lease component and its associated non-lease components as a single lease component and has allocated all of the contract consideration across lease components only. This will potentially result in the initial and subsequent measurement of the balances of the right-of-use asset and lease liability for leases being greater than if the policy election was not applied. The Company has existing net leases in which the non-lease components (e.g., common area maintenance, maintenance, consumables, etc.) are paid separately from rent based on actual costs incurred and therefore are not included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. As of March 31, 2019, an operating lease right-of-use asset of $7.2 million and an operating lease liability of $8.3 million are reflected on the consolidated balance sheet.

13. Discontinued operations

As previously disclosed, on September 25, 2018, Oxford Immunotec Global PLC, or the Company, entered into a Limited Liability Company Interest Purchase Agreement, or the Purchase Agreement, with Quest Diagnostics Incorporated, a Delaware corporation, or Quest, Oxford Immunotec Limited, a limited company incorporated in England and Wales and a wholly owned subsidiary of the Company, or Oxford Limited and Oxford Immunotec, LLC, a Delaware limited liability company (formerly known as Oxford Immunotec, Inc., a Delaware corporation) and a wholly owned subsidiary of the Company, or Oxford LLC, pursuant to which Oxford Limited agreed to sell, and Quest agreed to acquire, the Company’s U.S. laboratory services business, or the U.S. Laboratory Services Business, for gross proceeds of $170 million in cash, or the Transaction. Of this amount, approximately $32.3 million was paid directly to MidCap in settlement of all amounts due, which included prepayment and exit fees of approximately $2.3 million as described in Note 8. Loans payable.

As contemplated in the Purchase Agreement, Oxford Immunotec USA, Inc., a Delaware corporation and a newly formed wholly owned subsidiary of Oxford Immunotec Limited, or Oxford USA, joined the Purchase Agreement by way of a Joinder Agreement dated October 1, 2018.

16

The Transaction was consummated in accordance with the terms and conditions of the Purchase Agreement on November 6, 2018, or the Closing Date. Prior to and in connection with consummation of the Transaction, Oxford USA and Oxford LLC carried out a corporate restructuring pursuant to which (i) the assets and businesses of Oxford LLC other than the U.S. Laboratory Services Business were transferred to Oxford USA and (ii) Oxford LLC was converted into a limited liability company.

The U.S. Laboratory Services Business at the time of the sale had a carrying value of $27.9 million. The Company recorded a gain of $146.0 million, which amount was included in income from discontinued operations before income taxes in the Company’s consolidated statement of operations during the quarter ended December 31, 2018.

Additionally, pursuant to the terms of the Purchase Agreement, the parties entered into certain ancillary agreements as of the Closing Date, including: (i) a transitional services agreement, or TSA, that will continue, unless otherwise terminated, until each service included in the TSA has been completed, (ii) a technology license agreement that will remain in effect until the date of expiration or lapse of the last to expire or lapse Blood Stability Patent and (iii) a long-term supply agreement, or the Supply Agreement, pursuant to which Oxford USA agreed to sell, and Quest agreed to purchase, T-SPOT.TB test kits and related accessories from Oxford USA. The Supply Agreement will last for a period of seven years after the effective date, unless a party to the Supply Agreement terminates it early, as provided for in the Supply Agreement. In addition, the parties entered into a strategic collaboration agreement to drive continued growth of T-SPOT.TB testing in the U.S. that will remain in effect until the expiration or termination of the Supply Agreement.

In conjunction with the Purchase Agreement, Quest has agreed to purchase kits and accessories from the Company for an initial period of seven years after the effective date of the Purchase Agreement unless a party to the Purchase Agreement earlier terminates, as provided for in the Purchase Agreement.

During the three months ended March 31, 2018, Oxford Immunotec Limited sold kits to its discontinued operations, Oxford Immunotec, Inc., for use in the lab services business of $2.2 million that were eliminated in the Company’s consolidated results.

The following table presents the results of discontinued operations, which solely relate to 2018:

This management’s discussion and analysis of financial condition and results of operations contains forward-looking statements that involve risks and uncertainties. Please see “Special note regarding forward-looking statements” in this Quarterly Report on Form 10-Q for a discussion of the uncertainties, risks and assumptions associated with these statements. You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our condensed consolidated financial statements and the related notes to those statements included elsewhere in this Quarterly Report. In addition to our historical condensed consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, beliefs and expectations. Our actual results and the timing of events could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and in the Company’s 2018 Form 10-K, particularly in Part I, Item 1A, “Risk Factors.”

As previously disclosed, on September 25, 2018, Oxford Immunotec Global PLC, or the Company, entered into a Limited Liability Company Interest Purchase Agreement, or the Purchase Agreement, with Quest Diagnostics Incorporated, Oxford Immunotec Limited, a limited company incorporated in England and Wales and a wholly owned subsidiary of the Company, or Oxford Limited and Oxford Immunotec, LLC, a Delaware limited liability company (formerly known as Oxford Immunotec, Inc., a Delaware corporation) and a wholly owned subsidiary of the Company, or Oxford LLC, pursuant to which Oxford Limited agreed to sell, and Quest agreed to acquire, the Company’s U.S. laboratory services business, or the U.S. Laboratory Services Business, for gross proceeds of $170 million in cash, or the Transaction. Of this amount, approximately $32.3 million was paid directly to MidCap Financial Trust, or MidCap, in settlement of all amounts due.

In conjunction with the Transaction, all prior year amounts in this Management’s Discussion and Analysis of Financial Condition and Results of Operations have been recast to present our results, as if the Transaction had occurred prior to the earliest period presented. For more information on the Transaction, please see the below section entitled “Discontinued operations” and Note 13. Discontinued operations of our notes to consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

Overview

We are a global, high-growth diagnostics company focused on developing and commercializing proprietary tests for immunology and infectious disease by leveraging the technological, product development, manufacturing, quality, regulatory, and sales and marketing capabilities we have developed over our seventeen year history. Our proprietary T-SPOT.TB test utilizes our T-SPOT technology platform to test for tuberculosis, which is the leading cause of infectious disease death worldwide.

On November 6, 2018, we completed the sale of our U.S. Laboratory Services Business to Quest, for gross proceeds of $170 million in cash. This Transaction represented a strategic business shift and it had a major effect on our operations and financial results. Immediately following the Transaction, we had approximately 210 employees, including sales and marketing teams on three continents, and a laboratory in the United Kingdom.

We have incurred significant losses from inception and as of March 31, 2019 had an accumulated deficit of $82.3 million. We anticipate that our operating losses may decline following the sale of U.S. Laboratory Services Business to Quest, as we intend to reduce overhead costs and refocus the business on the sale of kits. Our revenue for the three months ended March 31, 2019 was $14.8 million and for the three months ended March 31, 2018 was $11.7 million. Our loss from continuing operations for the three months ended March 31, 2019 was $1.5 million and for the three months ended March 31, 2018 was $8.2 million.

Financial operations overview

Revenue

We generate revenue mainly from sales associated with our T-SPOT technology platform via our direct sales force and also through distributors. Our T-SPOT.TB test is our first commercialized product based on this technology.

We currently offer our T-SPOT.TB test as both an in vitro diagnostic kit and a service. In the former, we sell test kits and associated accessories to distributors for resale and directly to institutions and laboratories that perform TB testing. In the latter, we have an established clinical testing laboratory in the U.K., where we perform our T-SPOT.TB test on samples sent to us by customers. For the majority of our customers, we primarily negotiate pricing directly with our customers; our prices are influenced to some degree by the mechanism and level of funding our customers receive for performing tests for TB infection.

Revenue by type

By type, total revenues were as summarized in the table below.

Revenue
Product	$	13,841	$	10,129
Service		948		1,550
Total revenue	$	14,789	$	11,679

Revenue in the above table includes 2018 sales to the U.S. Laboratory Services Business at our intercompany transfer price that were formerly eliminated in consolidation. We also released unaudited pro forma condensed combined statements of operations in a Form 8-K that was filed with the Securities and Exchange Commission on January 7, 2019 that included the effect of the Transaction on revenues had the pricing and other terms of the Supply Agreement been in force in those prior periods. The unaudited pro forma condensed combined statements of operations were estimated based on the best information available at the time and assumptions that management believed to be factually supportable and reasonable. The unaudited pro forma condensed combined information was prepared for illustrative and informational purposes only and was not intended to reflect what our consolidated results of operations would have been had the Transaction occurred prior to the dates indicated and is not necessarily indicative of our future consolidated results of operations.

Revenue by geography

We have a direct sales force in the U.S., certain European countries and Japan as well as market development personnel in China and South Korea. In parts of the world where we do not maintain a direct sales force, we market and sell our products through distributors. As a result, our revenue is denominated in multiple currencies.

The following table reflects revenue by geography (United States, Europe and rest of world, or Europe and ROW, and Asia) and as a percentage of total revenue, based on the billing address of our customers.

	Three months ended March 31,

Revenue in the above table includes 2018 sales to the U.S. Laboratory Services Business at our intercompany transfer price that were formerly eliminated in consolidation.

Cost of revenue and operating expenses

Cost of revenue and gross margin

Cost of revenue consists of direct labor expenses, including employee benefits and share-based compensation expenses, overhead expenses, material costs, cost of laboratory supplies, freight costs, royalties paid under license agreements, depreciation of laboratory equipment and leasehold improvements.

We expect our overall cost of revenue to increase as we continue to increase our volume of kits manufactured and tests performed. However, we also believe that through these increased volumes, we can achieve certain efficiencies in our manufacturing and laboratory operations that could help maintain or improve our overall margins.

During the three months ended March 31, 2019 and 2018, our cost of revenue represented 29% and 32%, respectively, of our total revenue.

	Three months ended March 31,

Cost of revenue
Product	$	3,915	$	2,652
Service		313		1,107
Total cost of revenue	$	4,228	$	3,759

Our gross profit represents total revenue less total cost of revenue, and gross margin is gross profit expressed as a percentage of total revenue. Our gross margins were 71% and 68%, respectively, for the three months ended March 31, 2019 and 2018.

Research and development expense

Our research and development efforts are focused on development programs to enhance our TB product offering. We are developing multiple product enhancements that aim to improve the clinical utility of our test and improve test workflow and automation.

Our research and development activities include performing research, development, clinical and regulatory activities and validating improvements to our technology and processes for the purposes of enhancing product performance. Research and development expense includes personnel-related expenses, including share-based compensation, fees for contractual and consulting services, clinical trial costs, travel costs, laboratory supplies, amortization, depreciation, rent, insurance and repairs and maintenance. We expense all research and development costs as incurred.

During the three months ended March 31, 2019 and 2018, our research and development expense represented 16% and 20%, respectively, of our total revenue.

Sales and marketing expense

Our sales and marketing expense includes costs associated with our sales organization, including our direct sales force and sales management, and our marketing, customer service and business development personnel. These expenses consist principally of salaries, commissions, bonuses and employee benefits for these personnel, including share-based compensation, as well as travel costs related to sales, marketing costs, including the cost of obtaining marketing data, customer service activities, medical education activities and overhead expenses. We expense all sales and marketing costs as incurred.

20

During the three-month periods ended March 31, 2019 and 2018, our sales and marketing expense represented 42% and 61%, respectively, of our total revenue.

General and administrative expense

Our general and administrative expense includes costs for our executive, accounting, treasury, finance, legal, information technology, or IT, and human resources functions. These expenses consist principally of salaries, bonuses and employee benefits for the personnel included in these functions, including share-based compensation and travel costs, professional services fees, such as consulting, audit, tax and legal fees, costs related to our Board of Directors, general corporate costs, overhead expenses, and bad debt expense. Additionally, general and administrative expense for the three months ended March 31, 2019 included a credit for income from a TSA with Quest that was entered into in conjunction with the Transaction. We expense all general and administrative expenses as incurred.

During the three months ended March 31, 2019 and 2018, our general and administrative expense represented 35% and 48%, respectively, of our total revenue.

Settlement expense

On June 30, 2017, we entered into a Release and Settlement Agreement, or the Settlement Agreement, with Statens Serum Institut, or SSI, to resolve outstanding disputes arising from the license agreement with SSI. The terms of the Settlement Agreement are confidential.

Interest income (expense), net

Interest income (expense), net includes interest income on our available cash balances, which are primarily invested in money market funds and repurchase agreements, primarily in U.S. government and agency securities, and bank savings accounts in the United States, United Kingdom, Germany, Japan, China and South Korea. Essentially all our cash is in the U.S. and the U.K. Interest expense for 2018 mainly related to our previous agreement with MidCap, or the MidCap Agreement, that provided us with $40 million in debt financing, comprised of both a term loan and a revolving line of credit. Upon closing of the Transaction, approximately $32.3 million was paid directly to MidCap in settlement of all amounts due. The payment to MidCap included prepayment and exit fees of approximately $2.3 million.

Foreign exchange losses

Foreign exchange losses largely resulted from U.S. Dollar denominated bank accounts, accounts receivable, and accounts payable reflected on the books of Oxford Immunotec Limited, which has a functional currency of the U.K. Pound Sterling. We are exposed to foreign exchange rate risk because we currently operate in three major regions of the world: the United States, Europe and ROW, and Asia, and our revenue is denominated in multiple currencies. Sales in the United States, China and South Korea are denominated in U.S. Dollars. Sales in Europe are denominated primarily in the U.K. Pound Sterling and Euro. As we grow Europe and ROW sales outside the United Kingdom and the Euro Zone, we may be subject to risk from additional currencies. Sales in Japan are denominated in Yen.

Monetary assets and liabilities that are denominated in foreign currencies are remeasured at the period-end closing rate with resulting unrealized exchange fluctuations. Realized exchange fluctuations result from the settlement of transactions in currencies other than the functional currencies of our businesses. The functional currencies of our businesses are U.S. Dollars, Pounds Sterling, Euros, Japanese Yen and Chinese Yuan, depending on the entity.

Other expense

Other expense includes other income and expense items.

Loss from discontinued operations

On November 6, 2018, we completed an agreement to sell our U.S. Laboratory Services Business to Quest. This agreement represents a strategic business shift having a major effect on our operations and financial results. Accordingly, the operations of this business have been reported in discontinued operations in the consolidated financial statements for 2018.

Revenue 

Revenue increased by 27% to $14.8 million for the three months ended March 31, 2019, compared to $11.7 million for the same period in 2018.

U.S. revenue, excluding revenue from discontinued operations, increased by 50% to $5.5 million for the three months ended March 31, 2019, compared to $3.7 million for the same period in 2018, due to growth in testing volumes and higher average selling prices in 2019, as compared to 2018 average selling prices which were the intercompany transfer price formerly eliminated in consolidation, partially offset by a $741,000 decrease in revenue resulting from our withdrawal from the blood donor screening market in 2018.

Asia revenue increased by 13% to $6.5 million for the three months ended March 31, 2019 compared to the same period in 2018, due primarily to shipments to China reflecting growth in testing. On a non-Generally Accepted Accounting Principles, or non-GAAP, constant currency basis, revenue for Asia would have increased by 15%. Europe and ROW revenue increased 24% to $2.8 million for the three months ended March 31, 2019, compared to the same period in 2018, due mainly to strong growth in TB sales. On a non-GAAP constant currency basis, Europe and ROW revenue would have increased by 32% in 2019 compared to 2018.

Changes in revenue include the impact of changes in foreign currency exchange rates. We use the non-GAAP financial measure “constant currency basis” in our filings to show changes in our revenue without giving effect to period-to-period currency fluctuations. Under U.S. GAAP, revenues received in local (non-U.S. Dollar) currencies are translated into U.S. Dollars at the average exchange rate for the period presented. When we use the term “constant currency basis”, it means that we have translated local currency revenues for the prior reporting period into U.S. Dollars using the same average foreign currency exchange rates for the conversion of revenues into U.S. Dollars that we used to translate local currency revenues for the comparable reporting period of the current year. We then calculate the change, as a percentage, from the prior period revenues using the current period exchange rates versus the current period revenues. This resulting percentage is a non-GAAP measure referring to a change as a percentage on a “constant currency basis”. We consider the use of a period over period revenue comparison on a constant currency basis to be helpful to investors, as it provides a revenue growth measure free of positive or negative volatility due to currency fluctuations.

Total cost of revenue	$	4,228	$	3,759	$	469			12	%

Research and development expense

Research and development expense decreased to $2.3 million for the three months ended March 31, 2019 from $2.4 million for the same period in 2018. The decrease included a credit for share-based compensation of $180,000 related to the departure of an executive during the first quarter of 2019. As a percentage of total revenue, research and development expense declined to 16% for the three months ended March 31, 2019 compared to 20% for the same period in 2018.

Sales and marketing expense 

Sales and marketing expense decreased to $6.3 million for the three months ended March 31, 2019 from $7.2 million for the same period in 2018. The decrease was largely due to a $685,000 decrease in salary and other employee related expenses, along with a $225,000 decrease in marketing costs due, in part, to the timing of certain marketing initiatives, as we have repurposed spend around our new business model. As a percentage of total revenue, sales and marketing expense declined to 42% for the three months ended March 31, 2019 compared to 61% for the same period in 2018.

General and administrative expense

General and administrative expense decreased to $5.2 million for the three months ended March 31, 2019 from $5.6 million for the same period in 2018. The decrease largely resulted from payments under the TSA with Quest that have been credited against general and administrative expense. As a percentage of total revenue, general and administrative expense decreased to 35% for the three months ended March 31, 2019 from 48% for the same period in 2018.

Settlement expense

Settlement expense relates to the Settlement Agreement with SSI to resolve outstanding disputes arising from our previous license agreement. The terms of the Settlement Agreement are confidential.

Interest income (expense), net

Interest income (expense), net was income of $1.2 million for the three months ended March 31, 2019 reflecting interest income on proceeds received in the Transaction, compared to expense of $604,000 in the same period in 2018 resulting from the MidCap debt.

Foreign exchange losses

We recorded foreign exchange losses of $884,000 for the three months ended March 31, 2019, substantially all as a net result of U.S. Dollar denominated bank accounts, accounts receivable, and accounts payable reflected on the books of Oxford Immunotec Limited, which has a functional currency of the U.K. Pound Sterling. For the three months ended March 31, 2018, we recorded foreign exchange losses of $103,000. We are exposed to foreign exchange rate risk because we currently operate in three major regions of the world: the United States, Europe and ROW, and Asia, and our revenue is denominated in multiple currencies. Approximately 37% of our sales for the three months ended March 31, 2019 were in the United States, which are denominated in U.S. Dollars. Sales in China and South Korea are also denominated in U.S. Dollars. Sales in Europe are denominated primarily in the U.K. Pound Sterling and the Euro. As we grow Europe and ROW sales outside the United Kingdom and the Euro Zone, we may be subject to risk from additional currencies. Sales in Japan are denominated in Yen.

Our expenses are generally denominated in the currencies in which our operations are located, which are primarily in the United States, the United Kingdom, Japan, Europe, China and South Korea.

As we continue to grow our business outside the United States, our results of operations and cash flows will be subject to fluctuations due to changes in foreign currency exchange rates, which could harm our business in the future. To date, we have not entered into any foreign currency hedging contracts, although we may do so in the future.

24

Other expense

Other expense was $52,000 for the three months ended March 31, 2018. There was no other expense for the three months ended March 31, 2019.

Loss from discontinued operations

Discontinued operations represent the U.S. Laboratory Services Business that we sold to Quest. For financial statement purposes, the results of operations for the discontinued operations have been segregated from those of our continuing operations and are presented in our condensed consolidated financial statements as discontinued operations.

The loss from discontinued operations for the three months ended March 31, 2018 was $2.1 million. There was no loss from discontinued operations for the three months ended March 31, 2019.

Liquidity and capital resources

Sources of funds

Since our inception, we have incurred significant losses and negative cash flows from operations. For the three months ended March 31, 2019, we had a loss from continuing operations of $1.5 million and used $5.6 million of cash for operating activities. As of March 31, 2019, we had an accumulated deficit of $82.3 million. We incurred a loss from continuing operations of $8.2 million and used $12.1 million of cash for operating activities for the three months ended March 31, 2018.

On November 6, 2018, we completed the sale of our U.S. Laboratory Services Business to Quest, for gross proceeds of $170 million in cash. We received net proceeds of approximately $130.2 million in cash. In conjunction with the closing of the Transaction, approximately $32.3 million was paid directly to MidCap in settlement of all amounts due under our debt financing, which was comprised of both a term loan and a revolving line of credit. The payment to MidCap included prepayment and exit fees of approximately $2.3 million.

As of March 31, 2019, we had cash, cash equivalents, and restricted cash, of $189.6 million. We maintain our available cash balances in cash, money market funds and repurchase agreements primarily invested in U.S. government and agency securities, and bank savings accounts in the United States, United Kingdom, Germany, Japan, China and South Korea. Essentially all our cash is in the U.S. and the U.K.

Summary of cash flows

Cash flows for the three months ended March 31, 2019 and 2018

Operating activities from continuing operations

Net cash used in operating activities from continuing operations was $5.6 million during the three months ended March 31, 2019, which included a net loss of $1.5 million, non-cash expenses of $1.1 million, and cash used for changes in operating assets and liabilities of $5.2 million. The non-cash items included share-based compensation expense of $845,000, depreciation and amortization expense of $470,000, and non-cash rent expense of $59,000, partially offset by a credit of $279,000 for deferred income taxes. The cash used for changes in operating assets and liabilities included an increase in inventory of $2.0 million, an increase in prepaid expenses and other assets of $1.7 million, an increase in accounts receivable of $900,000, and a decrease in accounts payable and accrued expenses of $620,000, partially offset by an increase in deferred income of $85,000. The increase in inventory reflects timing. The increase in prepaid expenses and other assets reflects the timing of certain payments. The increase in accounts receivable reflects timing. The decrease in accounts payable and accrued liabilities was largely due to payments in the first three months of 2019 for royalties on intellectual property and bonuses that were accrued for at December 31, 2018, as well as the timing of payments.

Net cash used in operating activities from continuing operations was $12.1 million during the three months ended March 31, 2018, which included a net loss from continuing operations of $8.2 million, non-cash expenses of $ 2.3 million and cash used for changes in operating assets and liabilities of $6.2. The non-cash items consisted of share-based compensation expense of $1.8 million, depreciation and amortization expense of $341,000, accretion and amortization of loan fees expense of $140,000, and deferred income taxes of $43,000. The cash from changes in operating assets and liabilities included a decrease in accounts payable and accrued liabilities of $4.6 million, an increase in prepaid expenses and other assets of $1.1 million, an increase in accounts receivable of $315,000, and an increase in inventory of $304,000, partially offset by an increase in other liabilities of $58,000.

Investing activities from continuing operations

Net cash used in investing activities from continuing operations was $142,000 during the three months ended March 31, 2019 and $582,000 during the three months ended March 31, 2018, and consisted of purchases of property and equipment.

Financing activities from continuing operations

Net cash provided by financing activities from continuing operations was $1.7 million during the three months ended March 31, 2019, largely due to cash received on exercises of share options.

Net cash used in financing activities from continuing operations was $91,000 during the three months ended March 31, 2018.

Discontinued operations 

Net cash used in discontinued operations for 2018 related to cash used in investing activities of discontinued operations of $536,000, partially offset by $178,000 provided by operating activities of discontinued operations. There were no cash flows from discontinued operations for the three months ended March 31, 2019.

Employees

As of March 31, 2019, we had 215 employees. We have not experienced any work stoppages and we believe our employee relations are good.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company’s exposure to market risk from interest rate fluctuations, capital market fluctuations, and foreign currency exchange rate fluctuations has not materially changed from its exposure as of December 31, 2018, as described in Item 7A of our 2018 Form 10-K.

Item 4. Controls and Procedures 

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Quarterly Report. Based on their evaluation, they have concluded our disclosure controls and procedures were not effective as of March 31, 2019 due to a material weakness in internal control over financial reporting related to the accounting for income taxes that was disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Management’s Plan to Remediate the Material Weakness

As previously described in Part II, Item 9A. Controls and procedures of our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, we are working to implement a remediation plan to address the material weakness mentioned above. The material weakness will not be considered remediated, until applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We expect that the remediation of this material weakness will be completed by December 31, 2019.

(b) Changes in Internal Control Over Financial Reporting

There have been no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the period covered by this Quarterly Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We implemented internal controls to ensure we properly assessed the impact of the new accounting standard related to leases on our financial statements to facilitate its adoption on January 1, 2019. There were no significant changes to our internal control over financial reporting due to the adoption of the new standard. We will continue to review and document our disclosure controls and procedures, including our internal control over financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

1.

Business and basis of presentation

Description of business

Oxford Immunotec Global PLC, or the Company, is a global, high-growth diagnostics company focused on developing and commercializing proprietary tests for immunology and infectious disease by leveraging the technological, product development, manufacturing, quality, regulatory, and sales and marketing capabilities it has developed over its

seventeen

year history. The Company’s proprietary T-SPOT.

TB

test utilizes its T-SPOT technology platform to test for tuberculosis, which is the leading cause of infectious disease death worldwide.

Discontinued operations

The Company reports the results of operations of a business that either has been disposed of or is classified as held for sale, in accordance with Accounting Standards Codification, or ASC,

360,

Property, Plant, and Equipment

, in discontinued operations, as required by ASC

205,

Presentation of Financial Statements

. The Company presents such events as discontinued operations so long as the financial results can be clearly identified and the future operations and cash flows are completely eliminated from ongoing operations. The Company’s historical results for all periods presented are restated to account for businesses reported as discontinued operations in our Consolidated Financial Statements and these Notes. Unless otherwise specified, disclosures in our Consolidated Financial Statements and these Notes relate solely to our continuing operations.

As discussed in Note

13,

 

Discontinued operations

, on

September 25, 2018,

the Company entered into an agreement to sell the Company’s U.S. Laboratory Services Business to Quest Diagnostics Incorporated. The Transaction represents a strategic business shift having a major effect on the Company’s operations and financial results. Accordingly, operations have been reported in discontinued operations in the consolidated financial statements for all periods presented. The Transaction was consummated on

November 6, 2018

for gross proceeds of

$170

million in cash. Immediately following the Transaction, the Company had approximately

210

employees, including sales and marketing teams on

three

continents, and a laboratory in the United Kingdom.

Unaudited interim financial statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, for interim financial information and with the instructions to Form

10

-Q and Article

10

of Regulation S-

X.

Accordingly, they do

not

include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments, of a normal recurring nature, necessary for a fair statement of the financial position at

March 31, 2019,

the results of operations for the

three

-month periods ended

March 31, 2019

and

2018,

and the cash flows for the

three

-month periods ended

March 31, 2019

and

2018.

Interim results are

not

necessarily indicative of results for a full year.

The consolidated balance sheet presented as of

December 31, 2018,

has been derived from the audited consolidated financial statements as of that date. The consolidated financial statements and notes included in this report should be read in conjunction with the

2018

consolidated financial statements and notes included in the Company’s Annual Report on Form 

10

-K, as filed with the Securities and Exchange Commission on

March 28, 2019,

or the Company’s

2018

Form

10

-K.

Cash

,

cash equivalents

,

and restricted cash

The Company considers all highly liquid investments purchased with maturities at acquisition of

three

months or less to be cash equivalents. The Company maintains its available cash balances in cash, money market funds and repurchase agreements primarily invested in U.S. government and agency securities, and bank savings accounts in the United States, United Kingdom, Germany, Japan, China and South Korea. The Company maintains deposits in government insured financial institutions in excess of government insured limits. Management believes that the Company is

not

exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

Restricted cash relates to collateral for procurement cards issued by a U.S. commercial bank.

Cash, cash equivalents, and restricted cash consists of the following:

(in thousands)	March 31, 2019		December 31, 2018
Cash and cash equivalents	$	189,518	$	192,844
Restricted cash, non-current		100		100
Total cash, cash equivalents, and restricted cash	$	189,618	$	192,944

Revenues

The Company’s revenues include product and service revenues. In general, revenue from diagnostic test kit sales and related accessories is recognized at a point in time based upon contractual rates. However, for contracts with tiered pricing provisions, if the tiered pricing constitutes a material right and spans across multiple reporting periods, the Company estimates the total transaction price at the beginning of each reset period (i.e. the period in which revenue at different tiers is earned and settled) based on expected volumes. The Company revises its estimates of variable consideration at each reporting date throughout each reset period. Service revenue is recorded based upon contractually established billing rates and recognized upon delivery of test results to the customer. See Note

2.

Revenue

for disaggregation of revenue by type and geography.

As of

March 31, 2019,

accounts receivables related to products and services were

$10.2

million. For the

three

months ended

March 31, 2019,

the Company had

no

material bad-debt expense and there were

no

material contract assets, contract liabilities or deferred contract costs recorded on the Condensed Consolidated Balance Sheet as of

March 31, 2019.

The Company generally expenses sales commissions when incurred because the amortization period would be less than

one

year.

Revenue expected to be recognized in any future year related to remaining performance obligations is

not

material.

Taxes assessed by governmental authorities on revenue, including sales and value added taxes, are recorded on a net basis (excluded from revenue) in the consolidated statements of operations.

Other than the following discussion regarding leases, the remainder of the significant accounting estimates and policies used in preparation of the condensed consolidated financial statements disclosed in Note

Description of business and significant accounting policies

Leases

In

February 2016,

the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update or ASU

2016

-

02,

Leases,

or ASU

2016

-

02,

to enhance the transparency and comparability of financial reporting related to leasing arrangements. The Company adopted ASU

2016

-

02

on

January 1, 2019,

or the effective date, and used the effective date as its date of initial application.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Most leases with a term greater than

one

year are recognized on the balance sheet as right-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected

not

to recognize on the balance sheet leases with terms of

one

year or less. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining lease term. The operating lease right-of-use assets also include any lease payments made prior to the commencement date and exclude lease incentives and initial direct costs incurred. The operating lease right-of-use assets are subsequently assessed for impairment in accordance with the Company’s accounting policy for long-lived assets. The interest rate implicit in lease contracts is typically

not

readily determinable. As a result, the Company utilizes its incremental borrowing rates, which are the rates incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The incremental borrowing rate was determined at lease commencement, or as of

January 1, 2019

for operating leases existing upon adoption of ASC

842.

The incremental borrowing rate is subsequently reassessed upon modification to the lease arrangement.

In accordance with the guidance in ASU

2016

-

02,

components of a lease should be split into

three

categories: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, maintenance, consumables, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed and in-substance fixed contract consideration (including any related to non-components) must be allocated based on fair values to the lease components and non-lease components.

Although separation of lease and non-lease components is required, certain practical expedients are available. Entities

may

elect the practical expedient to

not

separate lease and non-lease components and would instead account for each lease component and the related non-lease component together as a single component. The Company has elected to account for the lease and non-lease components of each of its operating leases as a single lease component and allocate all of the contract consideration to the lease component only. The lease component results in an operating lease right-of-use asset being recorded on the balance sheet and amortized on a straight-line basis as lease expense.

Recently Adopted Accounting Pronouncements

In

February 2016,

the FASB issued ASU

2016

-

02,

which requires lessees to reflect all leases with terms longer than

12

months on their balance sheets. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The FASB has subsequently issued amendments to the guidance, including the addition of an optional transition method. The Company’s process of evaluating the impact of ASU

2016

-

02

has included reviewing all forms of leases and performing a completeness assessment over the lease population. The Company adopted ASU

2016

-

02

on

Note 3 - Fair Value Measurement

Mar. 31, 2019

Notes to Financial Statements

Fair Value Disclosures [Text Block]

3.

Fair value measurement

As a basis for determining the fair value of certain of the Company’s financial instruments, the Company utilizes a

three

-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level

1—Observable

inputs such as quoted prices in active markets for identical assets or liabilities.

Level

2—Observable

inputs, other than Level

1

prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are

not

active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level

3—Unobservable

inputs that are supported by little or

no

market activity and that are significant to the fair value of the assets or liabilities.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The carrying amount of certain of the Company’s financial instruments, including cash, accounts receivable, prepaid expenses and other assets, accounts payable, and accrued liabilities approximate fair value due to their short term nature.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the entire fair value measurement requires management to make judgments and consider factors specific to the asset or liability.

The Company had a term loan outstanding under an agreement with MidCap Financial Trust, or MidCap, at

March 31, 2018.

The amount outstanding on the term loan was reported at its carrying value in the accompanying balance sheet at that date. The estimated fair value of the term loan

,

 based upon market rates at the time for similar borrowings, as measured using Level 

2

 inputs, approximated the carrying amount as presented on the consolidated balance sheets. In connection with the sale of the U.S. Laboratory Services Business to Quest on

November 6, 2018,

approximately

$32.3

million of the gross proceeds received pursuant to the Transaction, was paid directly to MidCap to repay the outstanding indebtedness under an agreement with MidCap Financial Trust, or the MidCap Agreement, which included prepayment and exit fees of approximately

On

October 4, 2016,

the Company entered into an agreement with MidCap Financial Trust, or the MidCap Agreement, that provided it with

$40

million in debt financing, comprised of both a term loan and a revolving line of credit. The MidCap Agreement provided the Company with a term loan of

$30

million, which matured

five

years from closing. The term loan accrued interest at a rate of LIBOR plus

7.60%

with interest only payments for the

first

24

months, with the ability to extend to

48

months subject to certain conditions, before the loan began to amortize. The MidCap Agreement also provided the Company with a revolving line of credit of up to

$10

million, which matured

five

years from closing. The revolving line of credit accrued interest at a rate of LIBOR plus

4.45%.

The Company was also required to pay the lenders an unused line fee equal to

0.50%

per annum of the average unused portion of the revolving line of credit. Based on certain conditions, both the term loan and revolving line of credit could have been increased by an additional

$10

million for a total of

$60

million.

In connection with the sale of the U.S. Laboratory Services Business to Quest pursuant to a Limited Liability Company Interest Purchase Agreement on

November 6, 2018,

approximately

$32.3

million of the gross proceeds received pursuant to the Transaction was paid directly to MidCap to repay the outstanding indebtedness under the MidCap Agreement, which included prepayment and exit fees of approximately

$2.3

million. In connection with the Company’s repayment of the outstanding indebtedness under the MidCap Agreement, the Term Loan and the Revolving Loan, and all related agreements thereunder, were terminated and all borrowings outstanding thereunder were repaid in full. The repayment resulted in a loss on extinguishment of debt of

$2.1

million, which represents the cash paid to settle the debt in excess of debt related balances at the time of settlement. As of

March 31, 2018,

the Company had a balance of the secured term loan due to MidCap of

. Lease commitments

The Company has operating leases for real estate and non-real estate in the United States, United Kingdom, China, Japan, and Korea. One such operating lease is a sublease for real estate. The Company does

not

have any material finance leases.

The Company leases office, storage/warehouse, laboratory and manufacturing space in Abingdon, U.K., which leases are due to expire at various dates from

June 11, 2019

to

June 18, 2033.

On

March 

1,

2013,

the Company signed a

five

year lease for its U.S. corporate headquarters in Marlborough, Massachusetts. In

August 2015,

the Company entered into a lease amendment for this location to extend the term of the lease by

two

years through

October 31, 2020.

In addition, the lease amendment expanded the Company’s office space at this location by

7,600

square feet to a new total of

22,100

square feet. The base rent for the combined space over the lease term will range from an initial low of

$36,000

per month, which includes

$12,000

per month for the expansion space commencing in early

2016,

to a high of

$39,000

per month. The Company will have an option to extend the lease for

one

additional term of

five

years.

In connection with the sale of our U.S. Laboratory Services Business to Quest, we entered into a sublease with Quest for approximately

9,000

square feet of warehousing and office space in Norwood, Massachusetts. The sublease expires in

November 2020.

The base rent for the space subject to sublease is approximately

$17,000

per month.

In

June 2018,

the Company entered into a lease for new space in Abingdon, England, which extends through

June 2033

that will allow it to combine its manufacturing, laboratory, storage and office operations into a single facility. The base rent on the facility over the lease term will range from

$39,000

per month to

$79,000

per month. With the exception of manufacturing and associated groups, our U.K. operations are now located in this facility.

Many of the Company’s leases contain options to renew and extend lease terms and options to terminate leases early. Reflected in the right-of-use asset and lease liability on the Company’s balance sheet are the periods provided by renewal and extension options that the Company is reasonably certain to exercise, as well as the periods provided by termination options that the Company is reasonably certain to

not

exercise.

The Company has existing leases that include variable lease and non-lease components that are

not

included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. Such payments primarily include common area maintenance charges and increases in rent payments that are driven by factors such as future changes in an index (e.g., the Consumer Price Index).

In calculating the present value of future lease payments, the Company has elected to utilize its incremental borrowing rate based on the remaining lease term at the date of adoption. The Company has elected to account for each lease component and its associated non-lease components as a single lease component and has allocated all of the contract consideration across lease components only. This will potentially result in the initial and subsequent measurement of the balances of the right-of-use asset and lease liability for leases being greater than if the policy election was

not

applied. The Company has existing net leases in which the non-lease components (e.g., common area maintenance, maintenance, consumables, etc.) are paid separately from rent based on actual costs incurred and therefore are

not

included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. As of

March 31, 2019,

an operating lease right-of-use asset of

$7.2

million and an operating lease liability of

$8.3

million are reflected on the consolidated balance sheet.

The elements of lease expense were as follows:

the Company entered into an agreement to sell the Company’s U.S. Laboratory Services Business to Quest Diagnostics Incorporated. The Transaction represents a strategic business shift having a major effect on the Company’s operations and financial results. Accordingly, operations have been reported in discontinued operations in the consolidated financial statements for all periods presented. The Transaction was consummated on

November 6, 2018

for gross proceeds of

$170

million in cash. Immediately following the Transaction, the Company had approximately

210

employees, including sales and marketing teams on

three

continents, and a laboratory in the United Kingdom.

Basis of Accounting, Policy [Policy Text Block]

Unaudited interim financial statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, for interim financial information and with the instructions to Form

10

-Q and Article

10

of Regulation S-

X.

Accordingly, they do

not

include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim condensed consolidated financial statements reflect all adjustments, of a normal recurring nature, necessary for a fair statement of the financial position at

March 31, 2019,

the results of operations for the

three

-month periods ended

March 31, 2019

and

2018,

and the cash flows for the

three

-month periods ended

March 31, 2019

and

2018.

Interim results are

not

necessarily indicative of results for a full year.

The consolidated balance sheet presented as of

December 31, 2018,

has been derived from the audited consolidated financial statements as of that date. The consolidated financial statements and notes included in this report should be read in conjunction with the

2018

consolidated financial statements and notes included in the Company’s Annual Report on Form

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Cash

,

cash equivalents

,

and restricted cash

The Company considers all highly liquid investments purchased with maturities at acquisition of

three

months or less to be cash equivalents. The Company maintains its available cash balances in cash, money market funds and repurchase agreements primarily invested in U.S. government and agency securities, and bank savings accounts in the United States, United Kingdom, Germany, Japan, China and South Korea. The Company maintains deposits in government insured financial institutions in excess of government insured limits. Management believes that the Company is

not

exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

Restricted cash relates to collateral for procurement cards issued by a U.S. commercial bank.

Cash, cash equivalents, and restricted cash consists of the following:

Revenue from Contract with Customer [Policy Text Block]

Revenues

The Company’s revenues include product and service revenues. In general, revenue from diagnostic test kit sales and related accessories is recognized at a point in time based upon contractual rates. However, for contracts with tiered pricing provisions, if the tiered pricing constitutes a material right and spans across multiple reporting periods, the Company estimates the total transaction price at the beginning of each reset period (i.e. the period in which revenue at different tiers is earned and settled) based on expected volumes. The Company revises its estimates of variable consideration at each reporting date throughout each reset period. Service revenue is recorded based upon contractually established billing rates and recognized upon delivery of test results to the customer. See Note

2.

Revenue

for disaggregation of revenue by type and geography.

As of

March 31, 2019,

accounts receivables related to products and services were

$10.2

million. For the

three

months ended

March 31, 2019,

the Company had

no

material bad-debt expense and there were

no

material contract assets, contract liabilities or deferred contract costs recorded on the Condensed Consolidated Balance Sheet as of

March 31, 2019.

The Company generally expenses sales commissions when incurred because the amortization period would be less than

one

year.

Revenue expected to be recognized in any future year related to remaining performance obligations is

not

material.

Taxes assessed by governmental authorities on revenue, including sales and value added taxes, are recorded on a net basis (excluded from revenue) in the consolidated statements of operations.

Other than the following discussion regarding leases, the remainder of the significant accounting estimates and policies used in preparation of the condensed consolidated financial statements disclosed in Note

Lessee, Leases [Policy Text Block]

Leases

In

February 2016,

the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update or ASU

2016

-

02,

Leases,

or ASU

2016

-

02,

to enhance the transparency and comparability of financial reporting related to leasing arrangements. The Company adopted ASU

2016

-

02

on

January 1, 2019,

or the effective date, and used the effective date as its date of initial application.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Most leases with a term greater than

one

year are recognized on the balance sheet as right-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected

not

to recognize on the balance sheet leases with terms of

one

year or less. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining lease term. The operating lease right-of-use assets also include any lease payments made prior to the commencement date and exclude lease incentives and initial direct costs incurred. The operating lease right-of-use assets are subsequently assessed for impairment in accordance with the Company’s accounting policy for long-lived assets. The interest rate implicit in lease contracts is typically

not

readily determinable. As a result, the Company utilizes its incremental borrowing rates, which are the rates incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The incremental borrowing rate was determined at lease commencement, or as of

January 1, 2019

for operating leases existing upon adoption of ASC

842.

The incremental borrowing rate is subsequently reassessed upon modification to the lease arrangement.

In accordance with the guidance in ASU

2016

-

02,

components of a lease should be split into

three

categories: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, maintenance, consumables, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed and in-substance fixed contract consideration (including any related to non-components) must be allocated based on fair values to the lease components and non-lease components.

Although separation of lease and non-lease components is required, certain practical expedients are available. Entities

may

elect the practical expedient to

not

separate lease and non-lease components and would instead account for each lease component and the related non-lease component together as a single component. The Company has elected to account for the lease and non-lease components of each of its operating leases as a single lease component and allocate all of the contract consideration to the lease component only. The lease component results in an operating lease right-of-use asset being recorded on the balance sheet and amortized on a straight-line basis as lease expense.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Pronouncements

In

February 2016,

the FASB issued ASU

2016

-

02,

which requires lessees to reflect all leases with terms longer than

12

months on their balance sheets. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The FASB has subsequently issued amendments to the guidance, including the addition of an optional transition method. The Company’s process of evaluating the impact of ASU

2016

-

02

has included reviewing all forms of leases and performing a completeness assessment over the lease population. The Company adopted ASU

2016

-

02

on

January 1, 2019

and applied the modified retrospective approach, which recognize a cumulative-effect adjustment, if any, to the opening balance of retained earnings. The Company took advantage of the transition package of practical expedients permitted within ASU

2016

-

02,

which among other things, allowed it to carryforward historical lease classifications. The Company made an accounting policy election that will keep leases with an initial term of

12

months or less and that do

not

include an option to purchase the underlying asset that the Company is reasonably certain to exercise off of the balance sheet and will result in recognizing those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. As a result of adopting ASU

2016

-

02,

the Company recognized right-of-use assets of about

$7.2

million and corresponding liabilities of about

$8.2

million for its existing lease portfolio on its consolidated balance sheets. The adoption of ASU

2016

-

02

has

not

had a material impact on the Company’s consolidated statements of operations or consolidated statements of cash flows. The Company has included additional disclosures in Note

the information that a company must consider is broadened in developing an expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss. The new guidance will be effective for the Company for annual and interim periods beginning after

December 15, 2019.

Early adoption is permitted for annual and interim periods beginning after

December 15, 2018.

The guidance is applied using a modified retrospective, or prospective approach, depending on a specific amendment. The Company does
