DIGIRAD CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1. Basis of Presentation
Basis of Presentation
The unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared in accordance with the U.S. Securities and Exchange Commission ("SEC") instructions for Quarterly Reports on Form 10-Q. Accordingly, the condensed consolidated financial statements are unaudited and do not contain all the information required by U.S. generally accepted accounting principles ("GAAP") to be included in a full set of financial statements. The unaudited condensed consolidated balance sheet at December 31, 2017 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for a complete set of financial statements. The audited consolidated financial statements for our fiscal year ended December 31, 2017, filed with the SEC on Form 10-K on February 28, 2018, include a summary of our significant accounting policies and should be read in conjunction with this Form 10-Q. In the opinion of management, all material adjustments necessary to present fairly the results of operations, cash flows, and balance sheets for such periods have been included in this Form 10-Q. All such adjustments are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of operations for the entire year.
As discussed in Note 2, the results of our Medical Device Sales and Services ("MDSS") reportable segment are presented as discontinued operations and, as such, are excluded from both continuing operations and segment results for all periods presented.
Use of Estimates
Preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results could differ from management’s estimates.
New Accounting Pronouncements
Recently Adopted Accounting Standards
In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. The pronouncement is effective for fiscal years beginning after December 15, 2017, and for interim periods within those periods, using a retrospective transition method to each period presented. We adopted ASU 2016-18 effective January 1, 2018 which resulted in an increase of $3.0 million in net cash flows used in financing activities that was previously reported for the nine months ended September 30, 2017.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which amended the existing accounting standards for the accounting for financial instruments. The amendments require equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income. The new standard is effective prospectively for fiscal years beginning after December 15, 2017. We adopted ASU 2016-01 on January 1, 2018. As a result of the adoption, we recorded an increase to retained earnings of $17 thousand to recognize the unrealized gains previously recorded within accumulated other comprehensive income. Subsequent changes in the fair value of our marketable securities will be recorded to other expense, net. See Note 8 for further details.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers which supersedes current revenue recognition guidance, including most industry-specific guidance. The guidance provides that an entity recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. We adopted Topic 606 as of January 1, 2018 using the modified retrospective transition method. Under the modified retrospective method, the Company would recognize the cumulative effect of initially applying the standard as an adjustment to opening retained earnings at the date of initial application; however, we did not have any material adjustments as of the date of the adoption. The comparative periods have not been restated and continue to be reported under the accounting standards in effect for those periods. See Note 3 for expanded revenue disclosures and updates to our revenue recognition policy.

7



In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires an entity to perform its annual, or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.  The amendment should be applied on a prospective basis.  The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.  Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.  We early adopted ASU 2017-04 effective April 1, 2018 in conjunction with the interim impairment test of goodwill performed during the quarter. See Note 7 for additional information on or interim goodwill impairment test performed.
New Accounting Standards To Be Adopted
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which amends the existing accounting standards for leases. The new standard requires lessees to record a right-of-use (“ROU”) asset and a corresponding lease liability on the balance sheet (with the exception of short-term leases). The new standard also requires expanded disclosures regarding leasing arrangements. The guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted for all entities. We will adopt ASU 2016-02 as of January 1, 2019 and will apply certain practical expedients offered in the guidance, such as those that state that we need not reassess whether expired or existing contracts contain leases, reevaluate the classification of expired or existing leases, or reassess initial direct costs for existing leases. We have substantially completed the process of identifying existing lease contracts and are currently performing detailed evaluations of the leases under the new accounting requirements. We believe the most significant changes to the financial statements relate to the recognition of right-of-use assets and offsetting lease liabilities in the condensed consolidated balance sheet for operating leases. The actual impact on the condensed consolidated balance sheet will be contingent upon our population of operating leases at adoption; however, we do not expect the standard to have a material impact on cash flows or results of operations.
Note 2. Discontinued Operations
On February 1, 2018, the Company completed the sale of its customer contracts relating to our MDSS post-warranty service business to Philips North America LLC ("Philips") pursuant to an Asset Purchase Agreement, dated as of December 22, 2017 for $8.0 million. The total cash proceeds were adjusted for deferred revenue liabilities assigned to Philips at the closing date, as well as $0.5 million of proceeds held in escrow, subject to claims for breaches of general representation and warranties, which was recorded in other current assets at the date of sale. In September 2018, Philips notified the Company of claims against the escrow relating to alleged pre-existing conditions for certain equipment under service contracts at the time of sale. The Company is currently in discussion with Philips and expects to reach a final settlement during the fourth quarter of 2018. During the three months ended September 30, 2018, we recorded a reserve of approximately $0.1 million against such escrowed amounts, reflecting management's best estimate for the potential claim settlement with Philips.
Prior to the contemplation of the transaction entered into above, on September 28, 2017, we received notification from Philips that our distribution agreement to sell Philips imaging systems on a commission basis would be terminated, effective December 31, 2017. As a result, our product sales activities within our MDSS reportable segment were also discontinued effective in the first quarter of 2018.
The Company deemed the disposition of our MDSS reportable segment in the first quarter of 2018 to represent a strategic shift that will have a major effect on our operations and financial results, in accordance with the provisions of FASB authoritative guidance on the presentation of financial statements, we have classified the results of our MDSS segment as discontinued operations in our condensed consolidated statement of operations for all periods presented. Additionally, the related assets and liabilities associated with the discontinued operations were reclassified as held for sale in our condensed consolidated balance sheet.
The Company has allocated a portion of interest expense to discontinued operations since the proceeds received from the sale were required to be used to pay down outstanding borrowings under our revolving credit facility with Comerica Bank, a Texas banking association ("Comerica"). The allocation was based on the ratio of proceeds received in the sale to total borrowings for the period. In addition, certain general and administrative costs related to corporate and shared service functions previously allocated to the MDSS reportable segment are not included in discontinued operations.

Note 3. Revenue
Product and Product-Related Revenues and Services Revenue
Product and product-related revenue are generated from the sale of gamma cameras and post-warranty maintenance service contracts within our Diagnostic Imaging reportable segment.
Services revenue are generated from providing diagnostic imaging and cardiac monitoring services to customers within our Diagnostic Services and Mobile Healthcare reportable segments. Services revenue also includes lease income generated from interim rentals of imaging systems to our customers.
Revenue Recognition
Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue.
The majority of our contracts have a single performance obligation as we provide a series of distinct services that are substantially the same and are transferred with the same pattern to the customer. For contracts with multiple performance obligations, we allocate the total transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We use an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available.
Our products are generally not sold with a right of return and the Company does not provide significant credits or incentives, which may be required for as variable consideration when estimating the amount of revenue to be recognized.

Nature of Goods and Services
Mobile Imaging and Cardiac Monitoring
Within our Diagnostic Services and Mobile Healthcare reportable segments, our sales are derived from providing services and materials to our customers, primarily physician practices and hospitals, that allow them to perform diagnostic imaging services at their site. We typically bundle our services in providing staffing, our imaging systems, licensing, radiopharmaceuticals, and supplies depending on our customers' needs. Our contracts with customers are typically entered into annually and are billed on a fixed rate per-day or per-scan basis, depending on terms of the contract. For the majority of these contracts, the Company has the right to invoice the customer in an amount that directly corresponds with the value to the customer of the Company's performance to date. The Company uses the practical expedient to recognize revenue corresponding with amounts we have the right to invoice for services performed.
Diagnostic Services also offers remote cardiac event monitoring services. These services include provision of a monitor, remote monitoring by registered nurses, and 24 hours a day, 7 days a week monitoring support for our patients and physician customers. We provide our services under contracts with our customers that typically allow for direct billing to Medicare, Medicaid, or third-party private payors once the monitoring cycle is complete. Typically, our contracts can be canceled at any time, and are generally used to define billing responsibilities amongst the parties.
Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model which allows us to bill Medicare, Medicaid, or a third-party healthcare insurer directly for services provided. We also receive reimbursement directly from patients through co-pays and self-pay arrangements. Billings for services reimbursed by third party payors, including Medicare, are recorded as revenue net of contractual allowances. Contractual allowances are estimated based on historical collections by Current Procedural Terminology (CPT) code for specific payors, or class of payors. Adjustments to the estimated receipts, based on final settlement with the third-party payors, are recorded upon settlement.
Camera
Within our Diagnostic Imaging segment, camera revenues are generated from the sale of internally developed solid-state gamma camera imaging systems. We recognize revenue upon transfer of control to the customer, which is generally upon delivery and acceptance. We also provide installation services and training on cameras we sell, primarily in the United States. Installation and initial training is generally performed shortly after delivery. The Company recognizes revenues for installation and training over time as the customer receives and consumes benefits provided as the Company performs the installation services.
Our sale of imaging systems includes a one-year warranty which we account for as an assurance-type warranty. The expected costs associated with our standard warranties and field service actions continue to be recognized as expense when cameras are sold. Maintenance service contracts sold beyond the term of our standard warranties are accounted for as a service-type warranty and revenue is deferred and recognized ratably over the period of the obligation.

11



Camera Support
Within our Diagnostic Imaging segment, camera support revenue is derived from the sale of separately-priced extended maintenance contracts to camera owners, training, and paid service arrangements when a customer does not have an extended warranty and parts that are sold by the service department. Our separately priced service contracts range from 12 to 48 months. Service contracts are usually billed at the beginning of the contract period or at periodic intervals (e.g. monthly or quarterly) and revenue is recognized ratably over the term of the agreement.
Services and training revenues are recognized in the period the services and training are performed. Revenue for sales of parts are recognized when the parts are delivered to the customer and control is transferred.
Lease Income
Within primarily our Mobile Healthcare segment, we also generate income from interim rentals of our imaging systems to customers that are in the midst of new construction or refurbishing their current facilities. Rental contracts are structured as either a weekly or monthly payment arrangement and are accounted for as operating leases. Revenues are recognized on a straight-line basis over the term of the rental.
Deferred Revenues
We record deferred revenues when cash payments are received or due in advance of our performance, including amounts which are refundable. We have determined our contracts do not include a significant financing component. The majority of our deferred revenue relates to payments received on camera support post-warranty service contracts which are billed at the beginning of the annual contract period or at periodic intervals (e.g. monthly or quarterly).
At December 31, 2017, the Company deferred revenues balance was $2.4 million, of which $0.9 million and $2.7 million of this was recognized as revenue during the three and nine months ended September 30, 2018. As of September 30, 2018, deferred revenue was $1.6 million. The decrease of $0.8 million was mainly due to the timing of when customer payments are received in relation to the service contract period.
The Company has elected to use the practical expedient under ASC 606 to exclude disclosures of unsatisfied remaining performance obligations for (i) contracts having an original expected length of one year or less or (ii) contracts which the practical expedient has been applied to recognize revenue at the amount to which it has a right to invoice.
Contract Costs
We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract when the amortization period would have been one year or less. These costs mainly include the Company's internal sales commissions; under the terms of these programs these are generally earned and the costs are recognized at the time the revenue is recognized.

Note 4. Basic and Diluted Net Income (Loss) Per Share
For the three and nine months ended September 30, 2018 and 2017, basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares and vested restricted stock units outstanding during the period. Diluted net income per common share is calculated to give effect to all dilutive securities, if applicable, using the treasury stock method. In periods for which there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive.
The following table sets forth the reconciliation of shares used to compute basic and diluted net income (loss) per share for the periods indicated:

Note 7. Goodwill
The value of our goodwill is primarily derived from the acquisition of MD Office Solutions ("MD Office") in 2015, Telerhythmics, LLC ("Telerhythmics") in 2014, and substantially all of the assets of Ultrascan, Inc. ("Ultrascan") in 2007. During the nine months ended September 30, 2018, reporting units that carried goodwill balances included Digirad Imaging Solutions and Telerhythmics. The combined Digirad Imaging Solutions and Telerhythmics reporting units make up the Diagnostic Services reportable segment.

The Company tests goodwill for impairment annually during the fourth quarter of each year at the reporting unit level and on an interim basis if events or substantive changes in circumstances indicate that the carrying amount of a reporting unit may exceed its fair value.
During the second quarter of 2018, the Company's ongoing and continuous efforts to explore strategic alternatives across the entire business in order to maximize shareholder value triggered an interim impairment test during the quarter. As a result of additional market data and information that became available in connection with these efforts, the Company concluded that the carrying value of its Telerhythmics reporting unit was in excess of fair value and recorded a goodwill impairment charge of $0.5 million during the three and six months ended June 30, 2018. The remaining goodwill balance within this reporting unit as of September 30, 2018 was $0.2 million.

We did not reclassify any investments between levels in the fair value hierarchy during the nine months ended September 30, 2018.
The investment in equity securities consists of common stock of publicly traded companies. The fair value of these securities is based on the closing prices observed on September 30, 2018.
Securities Available-for-Sale
As of September 30, 2018, securities available-for-sale consist of investments in equity securities that are publicly traded. These investments include shares held in Birner Dental Management Services ("Birner Dental"), a publicly traded company whose board of directors include a current Director of the Company. We classify a portion of equity securities as available-for-sale and as current assets, as the sale of such securities may be required prior to maturity to execute management strategies. One of our equity securities, Perma-Fix Medical S.A. ("Perma-Fix Medical"), is classified as an other asset (non-current), as the investment is strategic in nature and our current intent is to hold the investment over a several year period. Securities available-for-sale are carried at fair value, with the unrealized gains and losses presented within 'other expense, net' on our condensed consolidated statement of operations. As of December 31, 2017, the accumulated unrealized gains on these investments was $17 thousand, which was reclassified from accumulated other comprehensive income into beginning retained earnings upon adoption of ASU 2016-01.

On June 21, 2017, the Company entered into a Revolving Credit Agreement (the “Comerica Credit Agreement”) with Comerica. The Comerica Credit Agreement provides for a five-year revolving credit facility with a maximum credit amount of $25.0 million maturing in June 2022, upon which a balloon payment on the balance is due. Under the Comerica Credit Facility, the Company can request the issuance of letters of credit in an aggregate amount not to exceed $1.0 million at any one time. In connection with the sale of our post-warranty service customer contracts to Philips, the Company entered into an Amendment No. 1 to the Comerica Credit Agreement, dated January 30, 2018 (the "Amendment"). The Amendment to the Comerica Credit Agreement reduced the revolving credit commitment from $25.0 million to $20.0 million. As of September 30, 2018, the Company had $0.2 million of letters of credit outstanding and had additional borrowing capacity under the Comerica Credit Agreement of $6.2 million.
In connection with the Amendment, during the nine months ended September 30, 2018, less than $0.1 million of unamortized loan fees were written off in proportion to the decrease in our borrowing capacity. As of September 30, 2018, the unamortized loan fees were $0.2 million, which are being amortized on a straight-line basis to interest expense over the five-year term.
At the Company’s option, the Comerica Credit Facility will bear interest at either (i) the LIBOR Rate, as defined in the Comerica Credit Agreement, plus a margin of 2.35%; or (ii) the PRR-based Rate, plus a margin of 0.5%. As further defined in the Comerica Credit Agreement, the "PRR-based Rate" means the greatest of (a) the Prime Rate in effect on such day (as defined in the Comerica Credit Agreement) plus 0.5%, or (b) the daily adjusting LIBOR Rate plus 2.50%. In addition to interest on outstanding borrowings under the Comerica Credit Facility, the revolving credit note bears an unused line fee of 0.25%, which is presented as interest expense. As of September 30, 2018, we had outstanding borrowings under the Comerica Credit Agreement of $13.6 million at a weighted average interest rate of 4.55%.
The Comerica Credit Agreement contains certain representations, warranties, events of default, as well as certain affirmative and negative covenants customary for credit agreements of this type. These covenants include restrictions on borrowings, investments and divestitures, as well as limitations on the Company’s ability to make certain restricted payments. The Comerica Credit Agreement requires us to comply with certain financial covenants, including a Fixed Charge Coverage Ratio and a Funded Debt to Adjusted EBITDA Ratio (each as defined in the Comerica Credit Agreement). The Fixed Charge Coverage Ratio is calculated based on the ratio of (a) Adjusted EBITDA, less (i) cash income taxes paid for such period, less (ii), FCCR Capital Expenditures (as defined in the Comerica Credit Agreement) made during such period, less (iii) payments, repurchases or redemptions of stock made during such period, less (iv) Distributions and Purchases (each as defined in the Comerica Credit Agreement) made during such period, to (b) (i) the Current Maturities of Long Term Debt (each as defined in the Comerica Credit Agreement) as of the last day of such period plus (ii) interest paid during such period. The Fixed Charge Coverage ratio is measured on a quarterly basis as of the most recent fiscal quarter end. Under the Comerica Credit Agreement, we must maintain a fixed charge ratio of at least 1.25 to 1.00 for each trailing twelve-month period as of the end of each fiscal quarter. The funded debt to Adjusted EBITDA ratio (as defined in the Comerica Credit Agreement) must be not more than 2.25 to 1.00 measured at each fiscal quarter.
Upon the occurrence and during the continuation of an event of default under the Comerica Credit Agreement, Comerica may, among other things, declare the loans and all other obligations under the Comerica Credit Agreement immediately due and payable and increase the interest rate at which loans and obligations under the Comerica Credit Agreement bear interest. Pursuant to a separate Security Agreement dated June 21, 2017, between the Company, its subsidiaries and Comerica Bank, the Comerica Credit Facility is secured by a first-priority security interest in substantially all of the assets (excluding real estate) of the Company and its subsidiaries and a pledge of all shares and membership interests of the Company’s subsidiaries.
On November 1, 2018, the Company entered into the Amendment No. 2 to the Comerica Credit Agreement (the "Second Amendment").  The Second Amendment, among other things, waives compliance under the Comerica Credit Agreement with the Fixed Charge Coverage Ratio financial covenants solely for the three months ended September 30, 2018.  At September 30, 2018, the Company was in compliance with all other covenants.  The Second Amendment also contains several amendments to the Credit Agreement including, among other things, (a) modifying the definition of  “Fixed Charge Coverage Ratio” to change how the Fixed Charge Coverage Ratio is calculated, (b) modifying the definition of  “FCCR Capital Expenditure” to reduce a threshold amount and (c) modifying the definitions of “Permitted Acquisition” and “Permitted Investments."

Note 10. Commitments and Contingencies
In addition to commitments and obligations in the ordinary course of business, we have been, and will likely continue to be, subject to litigation or administrative proceedings incidental to our business, such as claims related to customer disputes, employment practices, wage and hour disputes, product liability, professional liability, commercial disputes, licensure restrictions or denials, and warranty or patent infringement. Responding to litigation or administrative proceedings, regardless of whether they have merit, can be expensive and disruptive to normal business operations. We are not able to predict the timing or outcome of these matters.

Note 11. Income Taxes
We provide for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of differences between the tax basis of assets or liabilities and their carrying amounts in the financial statements. We provide a valuation allowance for deferred tax assets if it is more likely than not that these items will expire before we are able to realize their benefit. We calculate the valuation allowance in accordance with the authoritative guidance relating to income taxes, which requires an assessment of both positive and negative evidence regarding the realizability of these deferred tax assets, when measuring the need for a valuation allowance. Significant judgment is required in determining any valuation allowance against deferred tax assets. As of December 31, 2017, as a result of a three-year cumulative loss and recent events, such as the unanticipated termination of the Philips distribution agreement and its effect on our near term forecasted income, we concluded that a full valuation allowance was necessary to offset our deferred tax assets. We intend to maintain a valuation allowance until sufficient positive evidence exists to support its reversal.
Intraperiod tax allocation rules require us to allocate our provision for income taxes between continuing operations and other categories of comprehensive income, such as discontinued operations. In periods in which we have a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of comprehensive income, such as discontinued operations, we must consider that income in determining the amount of tax benefit that results from a loss in continuing operations and that shall be allocated to continuing operations. For the nine months ended September 30, 2018, we recorded income of $5.3 million, net of tax, in discontinued operations related to our MDSS reportable segment and a loss of $2.9 million, net of tax, in continuing operations.
As a result of the intraperiod tax allocation rules, for the nine months ended September 30, 2018, the Company recorded an income tax benefit of $0.9 million within continuing operations and $0.9 million of income tax expense within discontinued operations. For the nine months ended September 30, 2017, the Company recorded an income tax expense of $7.4 million and $0.5 million within continuing operations and discontinued operations, respectively.
For the nine months ended September 30, 2018, the Company expects to utilize $0.8 million of net operating losses associated with projected taxable income in discontinued operations mainly attributable to the gain on the sale of our MDSS post-warranty service contract business. The utilization of net operating losses in 2018 results in a reduction in our deferred tax asset balance, with a corresponding reduction in our valuation allowance, due to our full valuation allowance position discussed above.
As of September 30, 2018, we had unrecognized tax benefits of approximately $3.9 million related to uncertain tax positions. Included in the unrecognized tax benefits were $3.5 million of tax benefits that, if recognized, would reduce our annual effective tax rate, subject to the valuation allowance.
We file income tax returns in the US and in various state jurisdictions with varying statutes of limitations. We are no longer subject to income tax examination by tax authorities for years prior to 2014; however, our net operating loss and research credit carryovers arising prior to that year are subject to adjustment. It is our policy to recognize interest expense and penalties related to uncertain income tax matters as a component of income tax expense.

Note 12. Segments
Our reporting segments have been determined based on the nature of the products and/or services offered to customers or the nature of their function in the organization. We evaluate performance based on the gross profit and operating income (loss) excluding litigation reserve expense, goodwill impairment, and loss on sale of buildings. The Company does not identify or allocate its assets by operating segments.
During the first quarter of 2018, we have classified the results of our MDSS segment as discontinued operations in our condensed consolidated statement of operations for all periods presented. Accordingly, segment results have been recast for all periods presented to reflect MDSS as discontinued operations. As costs of shared service functions previously allocated to MDSS are not allocable to discontinued operations, prior period corporate costs have been reallocated amongst the continuing reportable segments. Segment information is as follows:

ITEM 2.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This management’s discussion and analysis of financial condition and results of operations (“MD&A”), contains forward-looking statements that involve risks and uncertainties. Please see “Important Information Regarding Forward-Looking Statements” for a discussion of the uncertainties, risks, and assumptions that may cause our actual results to differ materially from those discussed in the forward-looking statements. This discussion should be read in conjunction with our unaudited condensed consolidated financial statements and related notes thereto and the other disclosures contained elsewhere in this Quarterly Report on Form 10-Q, and the audited consolidated financial statements and related notes thereto for the fiscal year ended December 31, 2017, which were included in our Form 10-K, filed with the SEC on February 28, 2018.
The results of operations for the periods reflected herein are not necessarily indicative of results that may be expected for future periods.
Overview
Digirad delivers convenient, effective, and efficient healthcare solutions on an as needed, when needed, and where needed basis. Digirad's diverse portfolio of mobile healthcare solutions and diagnostic imaging equipment and services, provides hospitals, physician practices, and imaging centers throughout the United States with technology and services necessary to provide exceptional patient care in the rapidly changing healthcare environment.
Strategy
Our main strategic focus is to grow our business into an integrated healthcare services company that addresses the rapidly changing healthcare environment. We believe that there are many opportunities to provide outsourced and mobile healthcare services and solutions in the current healthcare environment. We believe this strategy will be accomplished by:
1.Focused organic growth from our core businesses;
2.Introducing new service offerings through our existing businesses or through acquisition; and
3.Acquiring similar or complementary healthcare service companies.
We continue to explore strategic alternatives to improve the market position and profitability of our product offerings in the marketplace, generate additional liquidity and enhance our valuation. We may pursue our goals during the next twelve months through organic growth and through strategic alternatives. Some of these alternatives have included, and could continue to include, selective acquisitions of business segments or entire businesses, divestitures of assets or divisions, or a restructuring of our company. We have also provided, and may from time to time in the future provide, information to interested parties relating to the foregoing.
Recent Announcement
On September 10, 2018, the Company issued a press release (the “Press Release”) reporting that the Company's Board of Directors (the "Board") had approved converting the Company into a diversified holding company (the “HoldCo Conversion”), and the Company’s acquisition of ATRM Holdings, Inc. (“ATRM”) as an initial “kick-off” transaction (the “ATRM Acquisition”). The Press Release also reported that the Company entered into a non-binding letter of intent (the “LOI”) relating to the ATRM Acquisition and had hired David Noble as its Chief Operating Officer on September 1, 2018.
Under the terms contemplated in the LOI, ATRM stockholders will receive consideration consisting of 0.4 shares of Digirad common stock for each share of outstanding ATRM common stock acquired by the Company in the ATRM Acquisition. The issuance of Digirad common stock in connection with the ATRM Acquisition is expected to increase the number of shares of outstanding Digirad common stock by less than 5%. The ATRM Acquisition will be subject to, among other things, ATRM becoming current with its SEC filings and the negotiation and execution of definitive documentation. The final terms of the ATRM Acquisition are subject to change depending on the outcome of the Company’s due diligence investigation and may differ from those reflected in the LOI. The ATRM Acquisition was approved by a special committee of independent directors of the Company.
Jeffrey E. Eberwein, the Chairman of the Company’s Board, owns approximately 17.4% of the outstanding common stock of ATRM. Mr. Eberwein is also the Chief Executive Officer of Lone Star Value Management, LLC, in which together with affiliated entities, hold 579,745 shares of ATRM's 10.00% Series B Cumulative Preferred Stock (the “Series B Stock”). Through these relationships and other relationships with affiliated entities, Mr. Eberwein may be deemed the beneficial owner of these securities. Mr. Eberwein disclaims beneficial ownership of Series B Stock, except to the extent of his pecuniary interest therein.

Business Segments
As of September 30, 2018, we operate the Company in three reportable segments:
1.Diagnostic Services
2.Mobile Healthcare
3.Diagnostic Imaging
Diagnostic Services. Through Diagnostic Services, we offer a convenient and economically efficient imaging and monitoring services program as an alternative to purchasing equipment or outsourcing the procedures to another physician or imaging center. For physicians who wish to perform nuclear imaging, echocardiography, vascular or general ultrasound tests, we provide imaging systems, qualified personnel, radiopharmaceuticals, licensing services, and the logistics required to perform imaging in their own offices, and thereby the ability to bill Medicare, Medicaid, or third-party healthcare insurers directly for those services, which are primarily cardiac in nature. We provide imaging services primarily to cardiologists, internal medicine physicians, and family practice doctors who typically enter annual contracts for a set number of days ranging from once per month to five times per week.
Diagnostic Services also offers remote cardiac event monitoring services through our Telerhythmics business. These services include provision of a monitor, remote monitoring by registered nurses, and 24 hours a day, 7 days a week monitoring support for our patients and physician customers. We offer modalities of mobile cardiac telemetry ("MCT"), mobile cardiac event monitoring, holter monitoring, and pacemaker analysis. These services offer flexibility and convenience to our customers who do not have to incur the costs of staffing, equipment, and logistics to monitor patients as part of their standard of care. Our cardiac event monitoring services are provided primarily through an independent diagnostic testing facility model that allows us to bill Medicare, Medicaid, or third-party healthcare insurers directly for our services, and is the only business at Digirad that bills Medicare, Medicaid, and private insurance directly.
Mobile Healthcare. Through Mobile Healthcare, we provide contract diagnostic imaging, including computerized tomography ("CT"), magnetic resonance imaging ("MRI"), positron emission tomography ("PET"), PET/CT, and nuclear medicine and healthcare expertise to hospitals, integrated delivery networks ("IDNs"), and federal institutions on a long-term contract basis, as well as interim (short-term) services to institutions that are in transition. These services are provided primarily when there is a cost, access, and efficiency component of providing the services directly rather than owning and operating the related services and equipment directly by our customers.
Diagnostic Imaging. Through Diagnostic Imaging, we sell our internally developed solid-state gamma cameras and camera maintenance contracts. Our cameras include nuclear cardiac imaging systems, as well as general purpose nuclear imaging systems. We sell our imaging systems to physician offices and hospitals primarily in the United States, although we have sold a small number of imaging systems internationally.
Discontinued Operations
Medical Device Sales and Service. Prior to January 1, 2018, through Medical Device Sales and Service ("MDSS), we provided: (a) contract sales services and (b) warranty and post-warranty services, under our contract with Philips Healthcare ("Philips"), within a defined region in the upper Midwest region of the United States. Under the contract sales services, we primarily sold Philips branded imaging and patient monitoring systems, including CT, MRI, PET, PET/CT systems, ultrasound and patient and monitoring systems, and received a commission on these sales. For our equipment contract sales services, we did not take title to the underlying equipment; it is delivered directly to the end user by Philips. Under our warranty and post-warranty services, we provided warranty and post-warranty services on certain Philips equipment within this territory related to equipment we sold or other equipment sold in the territory.
On September 28, 2017, we received a notice of termination (the "Termination Notice") from Philips that the Consolidated Agreement, dated April 1, 2014, as amended on June 9, 2015, between Philips and DMS Health Technologies ("DMS"), and the Remote Inside Sales Services Agreement dated March 23, 2016 (collectively, the "Philips Agreements"), were terminated upon the close of business on December 31, 2017 (“Termination Date”). The impact of the Termination Notice was to (a) end our contract sales services relationship with Philips as of December 31, 2017, effectively ending revenue associated with these services, and (b) end our relationship and support under our warranty and post-warranty services in the upper Midwest territory with Philips. However, the Philips Termination did not impact our ability to continue to service our existing contracts and allowed us opportunities to enter into new service contracts with customers outside the territory to which we were previously constrained.

20



Based on the Philips Termination, we carefully considered the opportunity to run the post-warranty service business outside the relationship with Philips, but determined that ultimately due to pricing challenges and logistics, the best economic decision was to sell the business to Philips. Therefore, on December 22, 2017, we entered into an Asset Purchase Agreement (the “Philips Purchase Agreement”) with Philips to sell all of our MDSS customer contracts relating to the post-warranty service business for $8.0 million (the “Philips Transaction”). The Philips Transaction is subject to certain post-closing adjustments. In connection with entering into the Philips Purchase Agreement, we entered into an agreement with Philips pursuant to which we continued to provide installation and warranty services pursuant to an existing Service Agreement until January 31, 2018. On February 1, 2018, the Philips Transaction was closed. Following the closing, the Company's MDSS reportable segment ceased to exist. As a result, the MDSS reportable segment is reported as discontinued operations in these unaudited condensed consolidated financial statements and related notes thereto.
Critical Accounting Policies and Estimates
In preparing our financial statements, we make estimates, assumptions and judgments that can have a significant impact on our revenue and net income or loss, as well as on the value of certain assets and liabilities on our balance sheet. We believe that the estimates, assumptions, and judgments involved in the accounting policies described in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 have the greatest potential impact on our financial statements, so we consider them to be our critical accounting policies and estimates. Except as discussed below, we believe there were no other significant changes in those critical accounting policies and estimates during the nine months ended September 30, 2018.
Revenue Recognition
Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue.
The majority of our contracts have a single performance obligation as we provide a series of distinct services that are substantially the same and are transferred with the same pattern to the customer. For contracts with multiple performance obligations, we allocate the total transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. We use an observable price to determine the stand-alone selling price for separate performance obligations or a cost plus margin approach when one is not available.
Our products are generally not sold with a right of return and the Company does not provide significant credits or incentives, which may be required to be accounted for as variable consideration when estimating the amount of revenue to be recognized.
Refer to Note 3 to the unaudited condensed consolidated financial statements for further updates to the Company's revenue recognition policy under the new revenue standard.

Diagnostic Services revenue increased $0.2 million, or 2.0%, compared to the prior year quarter, primarily due to a higher volume of imaging days ran and an increase in the average mobile imaging rate per day, partially offset by a $0.4 million decrease in revenue from our Telerhythmics business due to lower enrollments.
Mobile Healthcare revenue decreased $0.2 million, or 1.5%, compared to the prior year quarter, primarily due to lower mobile imaging revenue of $0.6 million resulting from higher cancellations, partially offset by an increase in interim rentals of $0.5 million primarily from higher utilization. The utilization of our interim rentals can vary in each period based on customers that are in the midst of new construction or refurbishing their current facilities.

The decrease in gross margin percentage was mainly due to higher labor costs as a percentage of revenue.
Mobile Healthcare gross profit decreased $0.7 million, or 45.4%, to $0.8 million in the current year quarter compared to $1.5 million in the prior year quarter, and gross margin percentage was 7.6% in the current year quarter compared to 13.8% in the prior year quarter. The decrease in gross margin percentage was primarily due to an unfavorable mix of revenue, as well as higher equipment and trailer repair costs of $0.2 million compared to the prior year quarter.

During the three months ended September 30, 2018, we completed the sale of buildings and a portion of land in our Fargo, North Dakota location with a net book value of $1.5 million for net cash proceeds of approximately $1.0 million, resulting in a loss on sale of $0.5 million.

Other expense, net for the three months ended September 30, 2018 and 2017 consisted of unrealized losses on available-for-sale equity securities. See Note 8 to the unaudited condensed consolidated financial statements for further information.
Interest expense, net, for the three months ended September 30, 2018 and 2017 is predominantly comprised of cash interest costs and related amortization of deferred issuance costs on our debt. A portion of interest costs has been allocated to discontinued operations for the three months ended September 30, 2017 since the proceeds received in the sale were required to be used to reduce our borrowings under our revolving credit facility with Comerica Bank, a Texas banking association ("Comerica").

Income Tax Benefit (Expense)
Income tax benefit was $0.4 million for the three months ended September 30, 2018 compared to income tax expense of $6.8 million for the three months ended September 30, 2017. For the three months ended September 30, 2018, income tax benefit was primarily a result of change in forecasted income. For the three months ended September 30, 2017, income tax expense was primarily comprised of an increase to our valuation allowance due to uncertainties related to our ability to utilize some of our net operating losses before they expire, predominantly as a result of the unanticipated termination of the Philips distribution agreement on our near term forecasted income. See Note 11 to the unaudited condensed consolidated financial statements for further information related to the Company's income taxes.
Income from Discontinued Operations
As described in Note 2 of the unaudited condensed consolidated financial statements, the results of our MDSS reportable segment have been reported as discontinued operations for all periods presented. See Note 2 for additional information regarding discontinued operations.

Diagnostic Services revenue increased $0.8 million, or 2.1%, compared to the prior year period, primarily due to a higher volume of imaging days ran and studies performed and an increase in the average mobile imaging rate per day, partially offset by a $0.7 million decrease in revenue from our Telerhythmics business due to lower enrollments.
Mobile Healthcare revenue decreased $0.5 million, or 1.7%, compared to the prior year period, primarily due to lower mobile imaging revenue of $1.6 million resulting from higher cancellations which were in part impacted by severe weather conditions during the first quarter of 2018, lower supplies and accessories revenue of $0.2 million, partially offset by an increase in interim rentals of $1.3 million due to higher utilization. The utilization of our interim rentals can vary in each period based on customers that are in the midst of new construction or refurbishing their current facilities.

Diagnostic Imaging revenue decreased $0.3 million, or 3.4%, compared to the prior year period, due to a decrease in camera revenue of $0.4 million primarily from a lower volume of cameras sold, partially offset by an increase in camera support time and material activities, which are variable in nature and based on customer needs.

Diagnostic Services gross profit decreased $0.5 million, or 6.5%, to $7.6 million in the current year period compared to $8.2 million in the prior year period, and the gross margin percentage was 20.2% in the current year period compared to 22.1% in the prior year period. The decrease in gross margin percentage was mainly due to higher labor costs as a percentage of revenue.
Mobile Healthcare gross profit decreased $1.8 million, or 35.2%, to $3.2 million in the current year period compared to $5.0 million in the prior year period, and gross margin percentage was 10.1% in the current year period compared to 15.3% in the prior year period. The decrease in gross margin percentage was primarily due to an unfavorable mix of services provided, as well as higher equipment and trailer repair costs of $0.7 million and health insurance costs of $0.3 million.
