NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(In thousands of U.S. dollars, except share and per share amounts or as otherwise disclosed)

NOTE 1 —The Company and its significant accounting policies

Description of Business —Sonim Technologies, Inc. was incorporated in the state of Delaware on August 5, 1999 and is headquartered in San Mateo, California. The Company is a leading U.S. provider of ultra-rugged mobile phones and accessories designed specifically for task workers physically engaged in their work environments, often in mission-critical roles.

Financial Statement Presentation—The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“ U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. The unaudited interim condensed consolidated financial statements, which reflect all adjustments (consisting of normal recurring items or items discussed herein) that management believes necessary to fairly state results of interim operations, should be read in conjunction with the Notes to Consolidated Financial Statements (including the Significant Accounting Policies and Recent Accounting Pronouncements) included in the Company’s audited consolidated financial statements for the year ended December 31, 2018, as filed with the SEC on Form S-1 (the “2018 Report”). Results of operations for interim periods are not necessarily indicative of annual results of operations. The unaudited condensed consolidated balance sheet at December 31, 2018 was extracted from the audited annual consolidated financial statements and does not include all disclosures required by GAAP for annual financial statements.

Principles of Consolidation — The accompanying condensed consolidated financial statements include the accounts of Sonim Technologies. Inc. and its wholly-owned foreign subsidiaries, Sonim Technologies Spain SL, Sonim Technologies India Private Limited, Sonim Technologies (Shenzhen) Limited, Sonim Technologies (Hong Kong) Limited, and Sonim Communications India Private Limited (collectively, the “Company”). All significant intercompany transactions and balances have been eliminated in consolidation.

Estimates —The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These estimates include, but are not limited to, estimates related to revenue recognition; valuation assumptions regarding the determination of the fair value of common stock, as well as stock warrants; the useful lives of our long-lived assets; product warranties; loss contingencies; and the recognition and measurement of income tax assets and liabilities, including uncertain tax positions; The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Significant accounting policies — There have been no material changes in the accounting policies from those disclosed in the audited 2018 consolidated financial statements and the related notes included in the filed Form S-1.

Revenue Recognition —We recognize revenues primarily from the sale of products. We also enter into multiple-element agreements that include a combination of products and NRE services.

Revenues from the sale of our mobile phones and accessories is recognized when all of the following conditions are met per Accounting Standards Codification, or ASC, Topic 605, Revenue Recognition, or ASC 605: (i) there is persuasive evidence of an arrangement; (ii) the product has been delivered to the customer; (iii) the collection of the fees is reasonably assured; and (iv) the amount of fees to be paid by the customer is fixed or determinable. Terms of product sales are generally FOB destination. Revenue recognition also incorporates allowances for discounts, price protection, returns and customer incentives that can be reasonably estimated.

Terms of product sales are generally FOB destination. Revenue recognition also incorporates allowances for discounts, price protection, returns and customer incentives that can be reasonably estimated. In addition to cooperative marketing and other incentive programs, the Company has arrangements with some distributors, which allow for price protection and limited rights of return, generally through stock rotation programs. Under the price protection programs, the Company gives distributors credits for the difference between the original price paid and the Company’s then current price. Under the stock rotation programs, certain distributors are able to exchange certain products based on the number of qualified purchases made during the period. The Company monitors and tracks these programs and records a provision, at the time of the sale, for future payments or credits granted as reductions of revenue based on historical experience. Recorded revenues are reduced by these allowances.

When revenue arrangements involve multiple elements, each element, referred to as a deliverable, is evaluated to determine whether it represents a separate unit of accounting in accordance with ASC 605-25, Revenue Recognition – Multiple-Element Arrangements. We perform this evaluation at the inception of an arrangement and as each item is delivered in the arrangement. Generally, we account for a deliverable separately if the delivered item has stand-alone value to the customer and delivery or performance of the undelivered item or service is probable and substantially in our control. When multiple elements can be separated into separate units of accounting, arrangement consideration is allocated at the inception of the arrangement, based on each unit’s relative selling price, and recognized based on the method most appropriate for that unit. When an arrangement includes NRE services which involve significant production, modification or customization of the product software that is essential to the functionality of the hardware, revenues are recognized according to the milestone method in accordance with the provisions of ASC Topic 605-35, Construction-Type and Production- Type Contract. Under this method, we recognize revenues from milestone payments when: (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement, and (i) we do not have ongoing performance requirements related to the achievement of the milestone earned. Milestone payments are considered substantive if all of the following conditions are met: the milestone payment (i) is commensurate with either our performance to achieve the milestone or the enhancement of the value of the delivered item or items as a result of a specific outcome resulting from our performance to achieve the milestone, (ii) relates solely to past performance, and (iii) is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement. If a milestone is deemed non-substantive, we defer, if applicable, and recognize such non-substantive milestones over the estimated period of performance applicable to each agreement on a straight-line basis, as appropriate.

Reverse Stock Split —In November 2018, the Company’s stockholders approved a one-for-fifteen reverse stock split of its common and convertible preferred stock which was effected on November 2, 2018. The par value of the common stock and convertible preferred stock were not adjusted as a result of the reverse stock split. Accordingly, all share and per share amounts for the period presented in the consolidated financial statements and notes thereto have been adjusted retrospectively to reflect this reverse stock split.

Deferred Offering Costs — On May 9, 2019, our registration statement on Form S-1 (File No. 333-230887) related to our initial public offering (“IPO”) was declared effective by the SEC, and our common stock began trading on The Nasdaq Stock Market LLC (“Nasdaq”) on May 10, 2019. Our IPO closed on May 14, 2019. Deferred offering costs, which consist of direct incremental legal, consulting, banking and accounting fees relating to the Company’s IPO, are capitalized and will be offset against proceeds from the IPO within stockholders’ equity. As of December 31, 2018, there was $63 of deferred offering costs within other non-current assets on the condensed consolidated balance sheets. During the three months ended March 31, 2019, an additional $1,709 in deferred offering costs were incurred. In connection with the IPO, as of March 31, 2019, all deferred offering costs were charged to prepaid expenses.

New accounting pronouncements:

Pronouncements adopted in 2018:

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s consolidated financial statements with another public company, which is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except share and per share amounts or as otherwise disclosed)

In July 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments with Down Round Features; II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-Controlling Interests with a Scope Exception. Part I of this update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on the basis of the pricing of future equity offerings. Current accounting guidance creates cost and complexity for entities that issue financial instruments (such as warrants and convertible instruments) with down round features that require fair value measurement of the entire instrument or conversion option. Part II of this update addresses the difficulty of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable noncontrolling interests. The amendments in Part II of this update do not have an accounting effect. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The adoption of ASU 2017-11 did not have an impact on the Company’s condensed consolidated financial statements for either period presented.

Pronouncements not yet adopted:

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820)—Changes to the Disclosure Requirements for Fair Value Measurement. The ASU eliminates certain disclosure requirements for fair value measurements for all entities and modifies some disclosure requirements. This ASU is effective for nonpublic entities beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating this new standard and the impact it will have on its existing accounting policies or presentation of the consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718). This ASU simplifies the accounting for share-based payments granted to nonemployees for goods and services. Under the ASU, most of the guidance on such payments to nonemployees would be aligned with the requirements for share-based payments granted to employees. This ASU is effective for nonpublic business entities for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating this new standard and the impact it will have on its existing accounting policies or presentation of the consolidated financial statements.

In October 2016, the FASB issued ASU 2016-16, Income Taxes—Intra-Entity Transfers of Assets Other Than Inventory. ASU 2016-16 requires entities to recognize income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments in ASU 2016-16 are effective for annual reporting periods beginning after December 15, 2018 and requires a modified retrospective method of adoption. Early adoption is permitted. The Company is in the process of determining the potential effects of this ASU on its consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments, which clarifies eight specific cash flow issues in an effort to reduce diversity in practice in how certain transactions are classified within the statement of cash flows. This ASU is effective for nonpublic business entities beginning after December 15, 2019 with early adoption permitted. The Company is currently evaluating this new standard and the impact it will have on its existing accounting policies or presentation of the consolidated statement of cash flows.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), as amended, which requires lessees to recognize a liability associated with obligations to make payments under the terms of the arrangement in addition to a right-of-use asset representing the lessee’s right to use, or control the use of the given asset assumed under the lease. The standard will be effective for nonpublic business entities for annual reporting periods beginning after December 15, 2019. The Company is currently evaluating these new standards and the impact they will have on its consolidated financial statements, information technology systems, process, and internal controls.

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 affect various aspects of recognition, measurement, presentation and disclosure of financial instruments. The amendment is effective for nonpublic business entities for annual periods beginning after December 15, 2018. Early application of certain provisions is permitted. The Company is in the process of determining the potential effects of this ASU on its consolidated financial statements.

In May 2014, the FASB, issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as amended, which affects any entity that either enters into contracts with customers to transfer goods and services or enters into contracts for the transfer of nonfinancial assets. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard has a five-step approach which includes identifying the contract or contracts, identifying the performance obligations, determining the transaction price, allocating the transaction price and recognizing revenue. In doing so, companies will need to use more judgment and make more estimates than under the currently effective guidance. These judgments may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The new standard may, in certain circumstances, impact the timing of when revenue is recognized for products shipped, and the timing and classification of certain sales incentives, which are expected to generally be recognized earlier than historical guidance. The standard also significantly expands the quantitative and qualitative disclosure requirements for revenue, which are intended to help users of financial statements understand the nature, amount, timing and uncertainty of revenue and the related cash flows. The standard will be effective for nonpublic business entities beginning for annual periods after December 15, 2018 and interim reporting periods within annual reporting periods beginning after December 15, 2019. While, early adoption is permitted, we plan to adopt the standard when it effective for us in 2019.

The guidance permits two methods of adoption, the full retrospective method applying the standard to each prior reporting period presented, or the modified retrospective method with a cumulative effect of initially applying the guidance recognized at the date of initial application. The standard also allows entities to apply certain practical expedients at their discretion. We currently anticipate adopting the standard using the modified retrospective method with a cumulative adjustment and will provide additional disclosures comparing results to previous U.S. GAAP in our fiscal 2019 consolidated financial statements. We plan to apply the new revenue standards only to contracts not completed as of the date of initial application, referred to as open contracts.

While the Company’s evaluation of the impact of this new guidance is not complete, we believe the impact of the new standard related to revenue recognition will not have a material impact on our consolidated financial statements other than potentially expanded disclosures. More judgements and estimates are required under Topic 606 than are required under Topic 605, including estimating the stand alone selling price (“SSP”) for each performance obligation identified within our arrangements with multiple elements and estimating the amount of variable considerations at inception of the arrangement. We will continue to evaluate sales incentives provided to our customers in order to determine the transaction price at inception of the contract.

This preliminary assessment is based on the revenue arrangements currently in place. The exact impact of ASC 606 will be dependent on facts and circumstances at adoption and could vary from quarter to quarter. New products or offerings, or changes to current offerings, may yield significantly different impacts than currently expected. Our conclusions will be reassessed periodically based on current facts and circumstances. We are also evaluating accounting systems, processes and internal controls over revenue recognition to assist us in the application of the new standard.

NOTE 2 —Fair value measurement

The fair value measurements standard establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the standard are described below:

Level 1—Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

Level 2—Inputs to the valuation methodology include:

SONIM TECHNOLOGIES, INC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of U.S. dollars, except share and per share amounts or as otherwise disclosed)

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3—Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

Following is a description of the valuation methodologies used for assets and liabilities measured at fair value. There have been no changes in the methodologies used at March 31, 2019 and 2018, and December 31, 2018.

Money market funds are classified within level 1 of the fair value hierarchy because they are valued using quoted market prices.

The warrant liability was classified within level 3 of the fair value hierarchy because there was no active market for the warrant or for similar warrants. The fair value of the Series A and Series B warrants at March 31, 2018, was estimated by first applying a weighting of the income approach and the market approach to determine the equity value of the Company. An Option-Pricing Method (“OPM”) was then used to allocate the total equity value of the Company to the different classes of equity according to their rights and preferences. As the Company was a private company at March 31, 2018, the fair value measurement was based on significant inputs that are not observable in the market thus represents Level 3 inputs. As of March 31, 2019, and December 31, 2018, as a result of the Company’s November 2018 stock conversion of preferred shares into common shares, all Series A and Series B warrants outstanding are now exercisable into common stock and are no longer required to be remeasured at fair value on a recurring basis.

Trade-in guarantee liability is classified within level 3 of the fair value hierarchy because the fair value measurement is based on inputs that are not observable in the market, including the probability and timing of a customer upgrading to a new device and the value of the upgraded device.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The following tables sets forth by level, within the fair value hierarchy, the Company’s assets and liabilities at fair value:

As of both March 31, 2019 and December 31, 2018, the Company had remaining borrowing capacity of $8,000 against the line of credit.

Long-Term Debt

Riley Loan— On October 26, 2017 (the “Effective Date”), the Company entered into a Subordinated Term Loan and Security agreement (the “Loan Agreement”) with B. Riley Principal Investments, LLC (“BRPI”), an affiliate of B. Riley Financial, Inc., a shareholder of the Company. Under the original Loan Agreement, the Company could borrow principal up to $10,000 via a subordinated secured convertible promissory note (the “Convertible Note”), with an optional conversion feature as described below.

During the year ended December 31, 2018, the Company amended the Loan Agreement to increase the available aggregate principal borrowings to $12,000. The 2018 amendments did not change the terms of the original Loan Agreement other than to provide a waiver of the defined prepayment penalties if any repayment does not reduce the principal amount outstanding below $10,000. The Loan Agreement, as amended, matures on September 1, 2022 (the “Maturity Date”) and carries a stated interest rate of 10% and provided that the first year of interest be compounded into the principal on October 26, 2018, with interest-only payments beginning thereafter.

As of both March 31, 2019 and December 31, 2018, the total outstanding borrowings under the Loan Agreement, as amended, was $12,000 and total accrued interest outstanding was $1,001.

Optional Conversion— On November 2, 2018, in conjunction with the Company’s conversion of all of its outstanding shares of preferred stock into shares of common stock (See Note 6) and the 15-to-1 reverse stock split, the Company amended the optional conversion terms of its existing Convertible Note. As amended the Convertible Note provides that at any time, on or prior to the Maturity Date, BRPI may elect to convert principal amounts outstanding, including accrued interest, as limited below, into shares of common stock at $8.87 per share. The number of shares of common stock to be issued upon conversion is limited to the sum of (A) the lesser of (i) the principal outstanding and (ii) the aggregate principal amount borrowed under the Loan Agreement to date multiplied by the Designated Percentage as described below, and (B) accrued interest. The “Designated Percentage” is one hundred percent (100%) if the conversion date is prior to the first anniversary of the Effective Date, seventy-five percent (75%) in Year 2 of the Loan Agreement, fifty percent (50%) in Year 3, twenty-five percent (25%) in Year 4, and twelve and a half of percent (12.5%) in the final year of the Loan Agreement on or prior to the Maturity Date.

Promissory Notes Payable—In 2014 and 2017, the Company entered into agreements with one of its suppliers, whereby certain of its trade payables for royalties and royalty up-front payments were converted to payment plans. In December 2018, the Company amended its accounts payable financing agreements, effective January 1, 2019, which provides for the $736 outstanding balance to be paid in twenty equal quarterly installments. The amounts due under these agreements would be paid in quarterly installments over periods from two to four years, with interest ranging up to 8%. Remaining balances are $619 and $718 at March 31, 2019 and December 31, 2018, respectively.

Other Financing Arrangements—In 2017, the Company entered three financing arrangements totaling approximately $472 with remaining maturity dates of June 2020 and August 2020. As of March 31, 2019 and December 31, 2018, the remaining balances are $184 and $238, respectively.

NOTE 8 —Stock-based Compensation

As of March 31, 2019, the Company had the 2012 Equity Incentive Plan (the “Option Plan”) in place. As of March 31, 2019, the number of shares available to be issued under the Option Plan was 459,075.

The Option Plan provides for the grant of incentive and nonstatutory stock options (“Options”), stock appreciation rights (“SAR”), restricted stock awards (“RSA”), and restricted stock unit awards (“RSU”) to employees, nonemployee directors, and consultants of the Company. Awards granted under the Option Plan generally becomes exercisable ratably over a two-year or four-year period following the date of grant and expire ten years from the date of grant. At the discretion of the Company’s Board of Directors, certain awards may be exercisable immediately at the date of grant but are subject to a repurchase right, under which the Company may buy back any unvested shares at their original exercise price in the event of an employee’s termination prior to full vesting. All other awards are exercisable only to the extent vested. At March 31, 2019 and December 31, 2018, there were no shares that had been early exercised that were subject to the Company’s repurchase right at that date. The exercise price or strike price for Options and SARs granted under the Option Plan must generally be at least equal to 100% of the fair value of the Company’s common stock at the date of grant, as determined by the Board of Directors. The exercise price of incentive stock options granted under the Option Plan to ten percent stockholders must be at least equal to 110% of the fair value of the Company’s common stock at the date of grant, as determined by the Board of Directors, and are not exercisable after five years from the date of grant.

Stock-based compensation expense for the three months ended March 31, 2019 and 2018 is as follows:

NOTE 9 —Income Taxes

In determining quarterly provisions for income taxes, the Company uses the annual estimated effective tax rate applied to the actual year-to-date profit or loss, adjusted for discrete items arising in that quarter. The Company’s annual estimated effective tax rate differs from the U.S. federal statutory rate primarily as a result of state taxes, foreign taxes, and changes in the Company’s valuation allowance against its deferred tax assets. For the three months ended March 31, 2019 and 2018, the Company recorded provisions for income taxes of $295, and $534, respectively.

On December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act (the Tax Act), which significantly changes existing U.S. tax laws, including a reduction in the corporate tax rate from 35% to 21%, a move from a worldwide tax system to a territorial system, as well as other changes.  The tax rate reduction was effective January 1, 2018.  Beginning in 2018, the Company became subject to the global intangible low-taxed income (GILTI) provisions of the Tax Act on the income of the Company’s foreign subsidiary.  The Company’s foreign subsidiaries are profitable in Q1 2019 and forecast profits for all of 2019.  The GILIT subjects the income of the foreign subsidiaries to U.S. taxation.  The Company’s accounting policy related to the GILTI is to treat GILTI related book/tax differences as period costs and to use the incremental cash tax savings approach in evaluating the Company’s U.S. net operating loss valuation allowance assessment.

The Company's income tax returns are subject to examinations by the Internal Revenue Service and other tax authorities in various jurisdictions.  In accordance with the guidance on the accounting for uncertainty in income taxes, the Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes.  These assessments can require considerable estimates and judgments.  As of March 31, 2019, the gross amount of unrecognized tax benefits was approximately $6,000, of which $700, if recognized, would reduce the effective income tax rate in future periods.  If the Company's estimate of income tax liabilities proves to be less than the ultimate assessment, then a further charge to expense would be required.  If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary.  The Company does not anticipate any material changes to its uncertain tax positions during the next twelve months.

NOTE 10 —Commitments and Contingencies

Royalty payments—The Company is required to pay per unit royalties to wireless essential patent holders and other providers of integrated technologies on mobile devices delivered, which, in aggregate, amount to less than 5% of net revenues associated with each unit, and expire in 2021 and 2023. Royalty expense for the three months ended March 31, 2019 and 2018 was $451 and $411, respectively, which are included in cost of revenues on the condensed consolidated statements of operations.

General litigation—The Company is involved in lawsuits, claims, investigation, and proceedings that arise in the ordinary course of business. The Company records a provision for a liability when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company reviews these provisions at least quarterly and adjusts them to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case.

Based on its experience, the Company believes that any settled amounts is not a meaningful indicator of the Company’s potential liability pertaining to litigation matters. The Company believes that it has valid defenses with respect to legal matters pending against it. Nevertheless, it is possible that cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies.

Indemnification—Under the terms of its agreements with wireless carriers and other partners, the Company has agreed to provide indemnification for intellectual property infringement claims related to Company’s product sold by them to their end customers. From time to time, the Company receives notices from these wireless carriers and other partners of a claim for infringement of intellectual property rights potentially related to their products. These infringement claims have been settled, dismissed, have not been further pursued by the customers, or are pending for further action by the Company.  

Contingent severance obligations—The Company has agreements in place with certain key employees guaranteeing severance payments under certain circumstances. Generally, in the event of termination by the Company without cause, termination due to death or disability, or resignation for good reason, the Company is obligated to the pay the employees: (i) any time before a Change in Control, amounts up to $1,057 or (ii) if at any time within 12 months of a Change in Control, amounts up to $1,407. In addition, in the event of termination by the Company with cause, the Company is obligated to pay the employees up to $88. The Company is obligated to pay one of the employees $140 if the Company has not been acquired or undertaken an Initial Public Offering at an equity

valuation in excess of $125,000 at the time of one the events as defined above. As of March 31, 2019, and December 31, 2018, no accrual has been recorded.

NOTE 11 —Related Party Transactions

Revenue transactions with a certain investor—During the three months ended March 31, 2018, the Company recognized revenue of $797 with an investor and holder of the August 2016 Series B warrants which were amended to common stock warrants in conjunction with the November 2018 preferred stock conversion event. The Company did not recognize any revenue with this investor during the three months ended March 31, 2019.

Management Services Agreement—In October 2017, the Company entered into a management services agreement with B. Riley Principal Investments, an investor, pursuant to which B. Riley Investments agreed to provide advisory and consulting services to the Company. The Company incurred approximately $50 in related consulting fees in each of the three months ended March 31, 2019 and 2018.  The closing of the Company’s IPO (see Note 14), the management services agreement was terminated in accordance with its terms.

NOTE 12 —Net Loss Per Share Attributable to Common Stockholders

Net loss per share attributable to common stockholders for the three months ended March 31, 2018 was determined by increasing Net loss for the three months then ended by the number of cumulative dividends, not yet declared, on the Company's previously outstanding convertible preferred stock. The following table sets forth the computation of the Company’s basic and diluted net loss per share attributable to common stockholders for the three months ended:

The potentially dilutive common shares that were excluded from the calculation of diluted net loss per share because their effect would have been antidilutive for the three months ended March 31, 2019 and 2018, respectively, are presented are as follows:

NOTE 13 —Entity Level Information

Segment Information—The Company operates in one reporting segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker, who is the chief executive officer, in deciding how to allocate resources and assessing performance. The Company’s chief operating decision maker allocates resources and assesses performance based upon discrete financial information at the consolidated level.

The following table summarizes the revenue by region based on ship-to destinations for the three months ended March 31, 2019 and 2018:

Long-lived assets located in the United States and Asia Pacific region were $1,690 and $465 and $2,013 and $393 as of March 31, 2019 and December 31, 2018, respectively.

The composition of revenues for the three months ended March 31, 2019 and 2018 is follows:

Concentrations of Credit Risk—The Company’s product revenues are concentrated in the technology industry, which is highly competitive and rapidly changing. Significant technological changes in the industry or customer requirements, or the emergence of competitive products with new capabilities or technologies, could adversely affect the Company’s consolidated operating results. Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents and accounts receivable. Cash and cash equivalents are deposited with high-quality, federally insured commercial banks in the United States and cash balances are in excess of federal insurance limits at March 31, 2019 and December 31, 2018. The Company generally does not require collateral or other security in support of accounts receivable. To reduce credit risk, management performs ongoing credit evaluations of its customers’ financial condition. The Company analyzes the need for reserves for potential credit losses and records allowances for doubtful accounts when necessary. The Company had allowances for such losses totaling approximately $7 and $11 at March 31, 2019 and December 31, 2018, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and the related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q and our final prospectus filed with the Securities and Exchange Commission (the “SEC”) pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on May 13, 2019 (“the Prospectus”). In addition to historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements.  You should review the section titled “Special Note Regarding Forward-Looking Statements” for a discussion of forward-looking statements and in Part II, Item 1A, “Risk Factors” for a discussion of factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis and elsewhere in this Quarterly Report on Form 10-Q and in our Prospectus.

Company Overview

We are a leading U.S. provider of ultra-rugged mobile phones and accessories designed specifically for task workers physically engaged in their work environments, often in mission-critical roles. We currently sell our ruggedized mobile phones and accessories to three of the four largest wireless carriers in the United States—AT&T, Sprint and Verizon—as well as the three largest wireless carriers in Canada—Bell, Rogers and Telus Mobility. Our phones and accessories connect workers with voice, data and workflow applications in two end-markets: industrial enterprise and public sector.

We generate revenues from sales of our (i) mobile phones, (ii) industrial-grade accessories and (iii) beginning in 2019, cloud-based software and application services. We sell our mobile phones and accessories primarily to wireless carriers in both the United States and Canada, who then resell our products in conjunction with network services to end customers.

Revenues have grown 46% to $26.5 million in the period ended March 31, 2019 from $18.2 million in the period ended March 31, 2018.  Such growth was primarily driven by the adoption of our complete product portfolio by the wireless carriers, which began in the first quarter of 2018 and lasted throughout 2018. In the period ended March 31, 2019, we launched the XP3, a rugged flip phone, with Sprint, extending our portfolio of stocked mobile phones at Sprint to three phones in the period ended March 31, 2019, from one phone in the same period in 2018.  We expect to continue unit sales volumes with these wireless carriers and anticipate launching the XP3 with other wireless carrier customers, including AT&T where we launched commercial sales in April 2019, in the second and third quarters of 2019 following the customization and certification processes. Because our U.S. sales channel is primarily comprised of large wireless carriers, the number of customers that we sell to is limited. For the period ended March 31, 2019, approximately 87% of our revenues came from wireless carrier customers and 82% came from our top five customers. For the period ended March 31, 2019, our smartphones accounted for approximately 35% of our units sold and our feature phones accounted for approximately 65% of our units sold, as compared to approximately 56% and 44% respectively for the period ended March 31, 2018.

In February 2019 we announced the introduction of Sonim Scan, a subscription service which integrates a barcode scanning engine with the native camera on the XP8, allowing end users to scan up to 45 1D or 2D barcodes per minute. Revenues from this new product are not significant.

Initial Public Offering

On May 9, 2019, our registration statement on Form S-1 (File No. 333-230887) related to our initial public offering (“IPO”) was declared effective by the SEC, and our common stock began trading on The Nasdaq Stock Market LLC (“Nasdaq”) on May 10, 2019. Our IPO closed on May 14, 2019. As a result, our condensed consolidated financial statements as of March 31, 2019 do not reflect the impact of our IPO. For additional information, see Note 13 - Subsequent Events to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Key Metrics

We review a variety of key financial metrics to help us evaluate growth trends, establish budgets, measure the effectiveness of our business strategies and assess operational efficiencies. In addition to our financial results determined in accordance with U.S. GAAP, we believe the following non-GAAP and operational measures are useful in evaluating our performance. related metrics.

Units Shipped

Our smartphones include the XP6, XP7, and XP8 models.  The number of smartphone units sold during the three months ended March 31, 2019 compared to the three months ended March 31, 2018 increased by 14%, primarily due to increased demand for the newer XP8, partially offset by decreased demand for older XP7 and XP6.

Our feature phones include the XP3, XP5, and XP5s models.  The number of feature phone units sold during the three months ended March 31, 2019 compared to the three months ended March 31, 2018 increased by 176%, primarily due to increased demand for the XP5s from several carriers, increase in demand for the older XP5 from one major carrier, and the introduction of our newest feature phone, the XP3.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) adjusted to exclude the impact of stock-based compensation expense, depreciation and amortization, interest expense, net, income tax expense and change in fair value of warrant liability. We define Adjusted Covenant EBITDA as Adjusted EBITDA further adjusted to exclude the impact of exchange rate changes. Adjusted EBITDA and Adjusted Covenant EBITDA are useful financial metrics in assessing our operating performance from period to period by excluding certain items that we believe are not representative of our core business, such as certain material non-cash items and other adjustments such as stock-based compensation and changes in the fair value of the warrant liability. We use Adjusted Covenant EBITDA to periodically assess compliance with certain covenants and other provisions under our loan and security agreement, as amended from time to time, or the Loan Agreement, with East West Bank, or EWB.

We believe that Adjusted EBITDA and Adjusted Covenant EBITDA, viewed in addition to, and not in lieu of, our reported GAAP results, provide useful information to investors regarding our performance and overall results of operations for various reasons, including:

We use Adjusted EBITDA and Adjusted Covenant EBITDA:

19

Adjusted EBITDA and Adjusted Covenant EBITDA have limitations as analytical tools, and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations include:

Set forth below is a reconciliation from net loss to Adjusted EBITDA and Adjusted Covenant EBITDA for the three months ended March 31, 2019 and 2018.

Factors Affecting Our Results of Operations

We believe that the growth and future success of our business depend on many factors. While these factors present significant opportunities for our business, they also pose important challenges that we must successfully address in order to sustain our growth and improve our results of operations.

Research and Development

We believe that our performance is significantly dependent on the investments we make in research and development and that we must continue to develop and introduce innovative new products on a two to three year cycle. While the hardware design of our devices is generally the same for all wireless carriers, each device must be configured to conform to the requirements of each wireless carrier’s network, resulting in higher development expenses as the number of wireless carriers we sell through increases. In addition to the design and configuration costs, each device must undergo a multi-month technical approval process at each carrier before it can be stocked. The approval process for each device for each carrier has historically cost up to $1.7 million. Prior to commencement of development of a product for certification, we generally do not receive any purchase orders or commitments. Following a carrier’s review of product concepts, we may receive a product award letter from that carrier to move forward with the development and certification process, at which time we may begin receiving advance purchase orders or commitments. Since the timing of when we seek technical approval with our wireless carriers tends to be cyclical in nature, quarter-over-quarter expenditures may vary significantly depending on the number of approvals in process during the quarter. If we fail to innovate and enhance our product offerings, our brand, market position and revenues may be adversely affected. If our research and development efforts are not successful, we will not recover these investments that we make.

New Customer Acquisitions

We are focused on continuing to acquire new customers, both in North America and overseas, to support our long-term growth. Historically, we have been dependent on a small number of wireless carriers distributing our products. We have invested, and expect to continue to invest, heavily in our sales and marketing efforts to drive new customer acquisition. In particular, a key part of our strategy is to further expand the use of our solutions over dedicated LTE networks in the public safety market. We will also continue to invest in and expand our international sales teams. As a result, we expect our sales and marketing costs to increase as we

20

seek to acquire new customers. Sales and marketing investments will often occur in advance of any sales benefits from these activities, and it may be difficult for us to determine if we are efficiently allocating our sales and marketing resources.

Seasonality and New Product Introduction

We have historically experienced lower net revenue in our first quarter compared to other quarters in our fiscal year due to seasonal demand associated with the introduction of new products to our lead customers.  New product introductions can significantly impact net revenue, gross profit and operating expenses. The timing of product introductions can also impact our net revenue as our wireless carrier customers prepare for a new product launch, and channel inventory of an older product often declines as the launch of a newer product approaches. Net revenue can also be affected when consumers and distributors anticipate a new product introduction. However, neither historical seasonal patterns nor historical patterns of product or service introductions should be considered reliable indicators of our future pattern of product or service introductions, future net sales or financial performance.

Results of Operations

The following tables present key components of our results of operation for the three months ended March 31, 2019, compared to results for a same period in 2018:

Net Revenue

For the three months ended March 31, 2019, net revenue increased to $26.5 million, a 46% increase compared to $18.2 million in net revenue for the three months ended March 31, 2018. Approximately 90% of net revenue for the first quarter of 2019 was attributable to North America, and Latin America compared to approximately 81% in the first quarter of 2018. Our top five customers accounted for 82% of net revenue in the first quarter of 2019, compared to 77% for the same period in 2018. The increase resulted primarily from i) a 14% increase in unit shipments of our smartphone product lines resulting from increased demand from several carriers, and ii) a 176% increase in unit shipments of our feature phones, resulting from a combination of increased demand from multiple carriers for the XP5s and the introduction of our newest product, the low cost XP3, to Sprint. We expect to begin shipments of the XP3 to other carriers in the second and third quarters of 2019.

Cost of Revenue and Gross Profit

Our gross profit for the three months ended March 31, 2019 increased by $4.1 million compared to the three months ended March 31, 2018. The improvement was driven primarily by an increase in net revenue of 46% from mobile phone sales, as well an increase in gross margin percentage from 28.9% in the first quarter of 2018 to 35.4 % in the first quarter of 2019. The increase in gross margin percentage can be attributed to both component and overhead cost reductions per unit attributable to improved efficiency and volume increases in our factory and higher average net selling prices for the XP5s and the XP8, partially offset by the introduction of the lower gross margin XP3 in the first quarter of 2019.

21

Operating Expenses and Net Operating Loss

Our net loss for the three months ended March 31, 2019 compared to the three months ended March 31, 2018 increased by $1.1 million, driven primarily by increases in operating expenses of $5.3 million, partially offset by an increase in net revenue and related gross profit. Operating expenses are summarized as follows;

Research and development. Research and development expenses increased by $3.3 million, or 63% from $5.1 million for the three months ended March 31, 2018 to $8.4 million for the three months ended March 31, 2019. These expenses increased primarily due to $1.8 million of costs associated with technical approval processes required by wireless carrier customers, as well as new product launches, and $1.4 million of an associated increase in employee headcount.

Sales and marketing. Sales and marketing expenses increased by $1.2 million, or 47% from $2.5 million for the three months ended March 31, 2018 to $3.7 million for the three months ended March 31, 2019. These expenses increased primarily due to $0.7 million of new employee hires and $0.5 million of new product launch marketing expenses.

General and administrative. General and administrative expenses increased by $0.9 million, or 55% from $1.6 million for the three months ended March 31, 2018 to $2.5 million for the three months ended March 31, 2019. These expenses increased primarily due to $0.2 million of increased employee compensation and hiring of new consultants and $0.5 million of professional fees.

Interest and Other Expense, net

The Company recorded $0.3 million in foreign exchange loss and $0.4 million in net interest expenses for the three months ended March 31, 2019, whereas the Company recorded $0.1 million in foreign exchange loss and $0.4 million in net interest expenses for the three months ended March 31, 2018.

Income Tax Expense

The Company recognized income tax expense of $0.3 million, and $0.5 million for the three months ended March 31, 2019 and 2018, respectively. Tax expense for the three months ended March 31, 2019 was $0.2 million lower than the tax expense for the three months ended March 31, 2018, primarily as a result of lower state tax expense recorded in the 2019 period compared to the 2018 period, and the application of interim period tax accounting principles.

Adjusted EBITDA

Our Adjusted EBITDA for the three months ended March 31, 2019 compared to the three months ended March 31, 2018 decreased by approximately $1.3 million, primarily due to higher operating expenses, partially offset by increased gross profit, as described above.

Liquidity and Capital Resources

Historically, we have funded operations from a combination of private equity financings, convertible loans from existing investors and borrowings under loan agreements. As of March 31, 2019, we had an aggregate of $13.0 million principal and deferred accrued interest outstanding under the B. Riley Convertible Note.  

Under the B. Riley Convertible Note, we have borrowed $12.0 million aggregate principal amount on a subordinated secured basis. Borrowings bear interest at 10% per year; interest amounts accrued and compounded into principal outstanding until October 2018, following which we are required to pay periodic interest in cash. The B. Riley Convertible Note matures on September 1, 2022. Borrowings under the B. Riley Convertible Note are secured by a subordinated lien on substantially all of our assets, subject to permitted liens. The principal amount of indebtedness under the B. Riley Convertible Note is convertible into shares of our common stock at $8.87 per share. Between the first and second anniversary of the original issue date of the note, between the second and the

22

third anniversary of the original issue date of the note, following the third anniversary of the original issue date of the note and following the fourth anniversary of the original issue date of the note, B. Riley Principal Investments, LLC may elect to convert 75.0%, 50.0%, 25.0% and 12.5%,respectively, of the then-outstanding total principal amount and accrued interest outstanding under the note at the conversion price per share of $8.87. We have the right to prepay amounts under the B. Riley Convertible Note at any time with a 2.0% prepayment fee if paid off before October 2019, a 1.0% prepayment fee if paid off between October 2019 and October 2020 and no prepayment fee thereafter. The prepayment fees are waived if the outstanding principal balance does not fall below $10.0 million following prepayment.

We maintain a credit line with EWB pursuant to the Loan Agreement. In the future, we may borrow up to $8.0 million under the line of credit available under the Loan Agreement. As of March 31, 2019, no amounts were outstanding under the Loan Agreement. Borrowings under the Loan Agreement bear interest at 1.0% plus the prime lending rate. Borrowings under the Loan Agreement are secured by a senior lien on substantially all of our assets, including inventory and receivables, subject to permitted liens. In the event of a default under the Loan Agreement, entities affiliated with B. Riley Financial and Investec Investments (UK) Limited, two of our stockholders, have the right to purchase the indebtedness under the Loan Agreement from EWB at par and to exercise remedies for the default, in their discretion, as the holders of the indebtedness.

The Loan Agreement contains certain negative and affirmative covenants as well as financial covenants, including covenants that restrict our ability to, among other things, incur or prepay indebtedness on subordinated debt, dispose of assets, engage in mergers and consolidations, make acquisitions or other investments, exceed annual capital expenditure limits, as defined, and make changes in the nature of the business. Objective events of default, therein, include, without limitation, nonpayment of principal, interest or other obligations, violation of the covenants, insolvency, and court-ordered judgments. Audited financial statements are required to be submitted to the lenders no later than 120 days after year end. In particular, we are required to maintain a minimum availability under the line of credit under the Loan Agreement of $750,000 and maintain a fixed charge coverage ratio, defined as the sum of Adjusted Covenant EBITDA plus capital expenditures minus taxes and dividends over fixed charges, of at least 1.05 to 1.00 as of the last of each month. In 2018, the financial covenants were amended to temporarily suspend the obligation to comply with the minimum fixed charge coverage ratio through September 30, 2018, to increase the minimum fixed charge coverage ratio as of December 31, 2018, and for the last day of each month thereafter, from 1.00 to 1.10, and to increase the minimum excess availability to $1.2 million. In 2018, the financial covenants were amended to permanently remove the requirement to maintain positive Adjusted Covenant EBITDA. As a result, as of the quarter ended March 31, 2018, we were no longer subject to this Adjusted Covenant EBITDA financial covenant. As of March 31, 2019, we were in compliance with all of the financial covenants and there were no events of default associated during the year then ended.

While we did not have any borrowings outstanding under the Loan Agreement as of March 31, 2019, if we fail to comply with the covenants in the Loan Agreement, including the minimum fixed charge coverage ratio, and are unable to cure the covenant violation, we would be restricted from making future borrowings.

Net cash as of March 31, 2019, was $9.9 million, or $3.1 million lower than net cash of $13.0 million at December 31, 2018. The decrease was driven primarily from cash used for operations, partially offset by proceeds from a private equity financing for common stock for an aggregate of $1.6 million that closed in January 2019.

The following table summarizes our sources and uses of cash for the periods presented:

Cash flows from operating activities

For the three months ended March 31, 2019, cash used in operating activities was $4.5 million, primarily attributable to net loss of $6.2 million, partially offset by a net change in our net operating assets and liabilities of $1.4 million, and non-cash charges of $0.3 million. Non-cash charges primarily consisted of $0.5 million in depreciation and amortization, partially offset by non-cash revenue of $0.3 million under our trade-in guarantee program. The change in our net operating assets and liabilities was primarily due to a $11.4 million decrease in accounts receivables, partially offset by a $7.2 million increase in inventory, a $2.3 million increase in prepaid expenses and other current assets, and a $0.6 million decrease in accounts payable and accrued expenses.

23

For the three months ended March 31, 2018, cash used in operating activities was $4.7 million, primarily attributable to net loss of $5.1 million and a net change in our net operating assets and liabilities of $0.3 million, offset by non-cash charges of $0.7 million. Non-cash charges primarily consisted of $0.5 million in depreciation and amortization and non-cash interest of $0.2 million. The change in our net operating assets and liabilities was primarily due to a $2.9 million increase in accounts receivables, a $2.8 million increase in inventory, a $2.5 million increase in prepaid expenses and other current assets, and a $0.4 million decrease in deferred revenue, partially offset by a $8.2 million increase in accounts payable.

Cash flows from investing activities

For the three months ended March 31, 2019, cash used in investing activities was $0.2 million, attributable to tooling development and purchases of software licenses of $0.1 million and purchases of property and equipment $0.1 million.

For the three months ended March 31, 2018, cash used in investing activities was $0.9 million, attributable to tooling development and purchases of software licenses of $0.8 million and purchases of property and equipment of $0.1 million.

Cash flows from financing activities

For the three months ended March 31, 2019, cash provided by financing activities was primarily derived from the proceeds from a private equity financing of shares of common stock that closed in January 2019 for an aggregate of $1.6 million, partially offset by the net repayment on the line of credit of $0.1 million.

For the three months ended March 31, 2018, cash provided by financing activities was $4.8 million, attributable primarily to net proceeds from additional net borrowings under the B. Riley Convertible Note of $3.0 million, and additional of net proceeds on our lines of credit of $1.7 million.

As of March 31, 2019, we had an aggregate of $13.0 million principal and deferred accrued interest outstanding with B. Riley Convertible Note, refer to Note 5-Borrowings under Riley Loan section. No amounts were outstanding under the Loan Agreement with East West Bank, refer to Note 5- Borrowings under Senior Credit Agreement section.

Based on our current plans and market conditions, and proceeds from the IPO, we believe that our existing cash resources, and cash generated from operations, will be sufficient to satisfy our anticipated cash requirements for at least the next 12 months.

Off-Balance Sheet Arrangements

As of March 31, 2019, we had not entered into any off-balance sheet arrangements and did not have any holdings in variable interest entities.

Item 3. Quantitative and qualitative disclosures about market risk

Interest rates risk 

We had cash and cash equivalents totaling $13.0 million and $9.8 million as of March 31, 2019 and December 31, 2018, respectively. We had no short-term investments as of March 31, 2019 and December 31, 2018. Our cash and cash equivalents consist of cash in bank accounts and money market funds. The primary objectives of our investment activities are to preserve principal and provide liquidity without significantly increasing risk. We do not enter into investments for trading or speculative purposes. Due to the nature of our cash and cash equivalents, a hypothetical 100 basis point change in interest rates would not have a material effect on the fair value of our portfolio. We therefore do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates. 

Item 4. Controls and Procedures.

(a) Evaluation of disclosure controls and procedures

Our management, with the participation of our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, prior to filing this Quarterly Report on Form 10-Q. Based on the evaluation of our disclosure controls and procedures, our chief executive officer and chief financial officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective at the reasonable assurance level.

24

(b) Changes in internal control over financial reporting

There were no changes in our internal control over financial reporting that occurred during the quarter to which this report related that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(c) Inherent Limitations on Effectiveness of Controls

In designing and evaluating disclosure controls and procedures, our management recognizes that any system of controls, however well designed and operated, can provide only reasonable assurance, and not absolute assurance, that the desired control objectives of the system are met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events. Because of these and other inherent limitations of control systems, there can be no assurance that any design will succeed in achieving its stated goals in all future circumstances. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our chief executive officer and our chief financial officer have concluded, based on their evaluation as of the end of the period covered by this quarterly report, that our disclosure controls and procedures were effective to provide reasonable assurance that the objectives of our disclosure control system were met.

25

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, revenues, financial condition or results of operations. The results of any future litigation cannot be predicted with certainty and, regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management time and resources and other factors.

Item 1A. Risk Factors.

Investing in our securities involves a great deal of risk. Careful consideration should be made of the following factors as well as other information included in this Quarterly Report on Form 10-Q before deciding to purchase our securities. There are many risks that affect our business and results of operations, some of which are beyond our control. If any of the following risks actually occur, our business, financial condition or operating results could be significantly harmed. This could cause the trading price of our common stock to decline, and you may lose all or part of your investment. Additional risks that we do not yet know of or that we currently think are immaterial may also affect our business and results of operations.

Risks Related to Our Business

We have not been profitable in recent years and may not achieve or maintain profitability in the future.

We have incurred significant net losses since 2013, and have an accumulated deficit of $149.7 million as of March 31, 2019. While we have experienced stronger revenue growth in recent periods, we are not certain whether or when we will obtain a high enough volume of sales of our products to sustain or increase our growth or achieve or maintain profitability in the future. We also expect our costs to increase in future periods, which could negatively impact our future operating results if our revenues do not increase. In particular, we expect to continue to expend substantial financial and other resources on:

These investments may not result in increased revenues or growth in our business. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays and other unknown factors that may result in losses in future periods. If we are unable to increase our revenues at a rate sufficient to offset the expected increase in our costs, our business, operating results and financial position may be harmed, and we may not be able to achieve or maintain profitability over the long term.

We rely on our channel partners to generate a substantial majority of our revenues. If these channel partners fail to perform or if we cannot enter into agreements with channel partners on favorable terms, our operating results could be significantly harmed.

A substantial majority of our revenues are generated through sales by our channel partners, which are primarily wireless carriers who sell our phones through their sales channels. To the extent our channel partners are unsuccessful in selling or do not promote our products, or we are unable to obtain and retain a sufficient number of high-quality channel partners, our business and operating results could be significantly harmed. We enter into master sales arrangements with the majority of our channel partners (including channel partners contributing over 90% of our total revenues for the three months ended March 31, 2019 and for the year ended December 31, 2018 under which our partners purchase our products for distribution on a purchase order basis. 

We enter into master sales arrangements with the majority of our channel partners (including channel partners contributing over 90% of our total revenues for the year ended December 31, 2018) under which our partners purchase our products for distribution on a purchase order basis. While these arrangements are typically long term, they generally do not contain any firm purchase volume commitments. As a result, our channel partners are not contractually obligated to purchase from us any minimum number of products. We are generally required to satisfy any and all purchase orders delivered to us within specified delivery windows, with limited exceptions (such as orders significantly in excess of forecasts). If we are unable to efficiently manage our supply and satisfy purchase orders on a timely basis to our channel partners, we may be in breach of our sales arrangements and lose potential sales. Our sales arrangements also generally include technical performance standards for our mobile phones and accessories sold, which vary by

26

channel partner. If a technical issue with any of our covered products exceeds certain preset failure thresholds for the relevant performance standard or standards, the channel partner typically has the right to cease selling the product, cancel open purchase orders and levy certain monetary penalties. If our products suffer technical issues or failures following sales to our channel partners, we may be subject to significant monetary penalties and our channel partners may cease making purchase orders, which would significantly harm our business and results of operations. In addition, our channel partners retain sole discretion in which of their stocked products to offer their customers. While we may offer limited customer incentives, we generally have limited to no control over which products our channel partners decide to offer or promote, which directly impacts the number of products that our partners will purchase from us.

Our channel partners may be unsuccessful in marketing, selling and supporting our solutions. They may also market, sell and support solutions that are competitive with ours, and may devote more resources to the marketing, sales and support of such products. They may have incentives to promote our competitors’ products in lieu of our products, particularly for our competitors with larger volumes of orders, more diverse product offerings and a longer relationship with our channel partners. As a result, our channel partners may stop selling our products completely. While we employ a small direct sales force, our channel partners have significantly larger sales teams who are not contractually obligated to promote any of our devices and often have multiple competing devices in stock to offer their customers. In addition, downstream sales by our channel partners often succeed due to attractive device prices and monthly rate plans, which we do not control. In certain cases, we may promote our own devices through customer incentives, typically in exchange for retail price reductions or contributions of funds for marketing purposes; however, there can be no assurance that any such incentives would contribute to increased purchases of our products. Further, given the impact of attractive pricing on ultimate sales, we generally must offer increased promotional funding or price reductions for our more expensive products. This promotional funding or price reductions operate to reduce our margins and significantly impact our profitability.

New sales channel partners may take several months or more to achieve significant sales. Our channel partner sales structure could subject us to lawsuits, potential liability and reputational harm if, for example, any of our channel partners misrepresents the functionality of our products or services to their customers, or violate laws or our corporate policies. Additionally, some of our master agreements with our wireless carrier customers contain most “favored nation” clauses. These clauses typically provide that if we enter into an agreement with another wireless carrier or customer on more favorable terms, we must offer some of those terms to our existing wireless carrier customers. These provisions may obligate us to provide different, more favorable, terms to our existing wireless carrier customers, which could, if applied, result in lower revenues or otherwise adversely impact our business, financial condition and results of operations.

If we fail to effectively manage our existing or future sales channel partners, our channel partners fail to promote our products effectively, we are unable to meet our obligations under our sales arrangements or future agreements that we may enter into with wireless carrier customers have terms that are more favorable to the customer, our business and results of operations would be harmed.

We are materially dependent on the adoption of our solutions by both the industrial enterprise and public sector markets, and if end customers in those markets do not purchase our solutions, our revenues will be adversely impacted, and we may not be able to expand into other markets.

Our revenues have been primarily in the industrial enterprise market, and we are materially dependent on the adoption of our solutions by both the industrial enterprise and public sector markets. End customers in the public sector market may remain, for reasons outside our control, tied to LMR solutions or other competitive alternatives to our phones. Sales of our products to these buyers may also be delayed or limited by these competitive conditions. If our products are not widely accepted by buyers in those markets, we may not be able to expand sales of our products into new markets, and our business, results of operations and financial condition may be adversely impacted.

We participate in a competitive industry, which may become more competitive. Competitors with greater resources and significant experience in high-volume product manufacturing may be able to respond more quickly and cost-effectively than we can to new or emerging technologies and changes in customer requirements.

We face significant competition in developing and selling our solutions. Our primary competitors in the non-rugged mobile device market include Apple Inc. and Samsung Electronics Co. Ltd. Our primary competitors in the rugged mobile device market include Bullitt Mobile Ltd. and Kyocera Corporation. We also face competition from large system integrators and manufacturers of private and public wireless network equipment and devices. Competitors in this space include Harris Corporation, JVC KENWOOD Corporation, Motorola Solutions, Inc., or MSI, and Tait International Limited. For the Data Capture and RFID portion of our product offerings, competitors include companies that provide a broad portfolio of barcode scanning products that are suitable for the majority of global market applications, such as Datalogic USA, Inc., Honeywell International Inc., Panasonic Corporation and Zebra Technologies Corporation.

27

We cannot assure we will be able to compete successfully against current or future competitors. Increased competition in mobile computing platforms, data capture products, or related accessories and software developments may result in price reductions, lower gross profit margins, and loss of market share, and could require increased spending on research and development, sales and marketing, and customer support. Some competitors may make strategic acquisitions or establish cooperative relationships with suppliers or companies that produce complementary products, which may create additional pressures on our competitive position in the marketplace.

Most of our competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater financial, technical, sales, marketing and other resources and experience than we do. In addition, because of the higher volume of components that many of our competitors purchase from their suppliers, they are able to keep their supply costs relatively low and, as a result, may be able to recognize higher margins on their product sales than we do. Many of our competitors may also have existing relationships with the channel partners who we use to sell our products, or with our potential customers. This competition may result in reduced prices, reduced margins and longer sales cycles for our products. Our competitors may also be able to more quickly and cost-effectively respond to new or emerging technologies and changes in customer requirements. The combination of brand strength, extensive distribution channels and financial resources of the larger vendors could cause us to lose market share and could reduce our margins on our products. If any of our larger competitors were to commit greater technical, sales, marketing and other resources to our markets, our ability to compete would be adversely impacted. If we are unable to successfully compete with our competitors, our sales would suffer and as a result our financial condition will be adversely impacted.

Defects in our products could reduce demand for our products and result in a loss of sales, delay in market acceptance and injury to our reputation, which would adversely impact our business.

Complex software, components and assemblies used in our products may contain undetected defects that are subsequently discovered at any point in the life of the product. For example, in 2018, we recalled one batch of our XP8 devices from two wireless carriers due to manufacturing defects. Defects in our products may result in a loss of sales, delay in market acceptance and injury to our reputation and increased warranty costs.

Additionally, our software may contain undetected errors, defects or bugs. Although we have not suffered significant harm from any errors, defects or bugs to date, we may discover significant errors, defects, or bugs in the future that we may not be able to correct or correct in a timely manner. It is possible that errors, defects or bugs will be found in our existing or future software products and related services with the potential for delays in, or loss of market acceptance of, our products and services, diversion of our resources, injury to our reputation, increased service and warranty expenses, and payment of damages.

Further, errors, defects or bugs in our solutions could be exploited by hackers or could otherwise result in an actual or perceived breach of our information systems. Alleviating any of these problems could require significant expense and could cause interruptions, delays or cessation of our product licensing, which would reduce demand for our products and result in a loss of sales, delay in market acceptance and injure our reputation and could adversely impact our business, results of operations and financial condition.

If our business does not grow as we expect, or if we fail to manage our growth effectively, our operating results and business would suffer.

Our ability to successfully grow our business depends on a number of factors including our ability to:

As usage of our solutions grows, we will need to continue to make investments to develop and implement new or updated solutions, technologies, security features and cloud-based infrastructure operations. In addition, we will need to appropriately scale our internal business systems and our services organization, including the suppliers of our detection equipment and customer support services, to serve our growing customer base. Any failure of, or delay in, these efforts could impair the performance of our solutions and reduce customer satisfaction.

28

Further, our growth could increase quickly and place a strain on our managerial, operational, financial and other resources, and our future operating results depend to a large extent on our ability to successfully manage our anticipated expansion and growth. To manage our growth successfully, we will need to continue to invest in sales and marketing, research and development, and general and administrative functions and other areas. We are likely to recognize the costs associated with these investments earlier than receiving some of the anticipated benefits, and the return on these investments may be lower, or may develop more slowly, than we expect, which could adversely impact our operating results.

If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities or develop new solutions or upgrades to our existing solutions, satisfy customer requirements, maintain the quality and security of our solutions or execute on our business plan, any of which could harm our business, operating results and financial condition.

We are required to undergo a lengthy customization and certification process for each wireless carrier customer, which increases our operating expenses, and failure to obtain such certification would adversely impact our results of operations and financial condition.

Each wireless carrier requires each of our devices to complete a thorough technical acceptance process before it can be stocked and sold. Such acceptance processes impose rigorous and complex requirements on our devices, which result in a lengthy testing and certification process, during which we incur substantial operating expenses related to the wireless carrier’s technical acceptance of our devices. The acceptance processes and related costs to us vary across carrier customers depending on carrier size and level of customization required. Generally, the certification process commences within one to three months of product concept development. During this development stage, certain carriers provide a technology roadmap and target demographics, allowing us to define product specifications to meet carrier goals, while other carriers provide defined specifications and preferred price points. Once we receive approval of a product concept by the carrier, we and the carrier advance the product to the development stage. When the product is close to being a functioning model, we commence internal quality assurance processes and field testing, which may include third-party lab testing, in-market field testing and interoperability testing. Finally, as the last step in the testing phase, the wireless carrier typically conducts testing itself, following which the product may be certified and stocked. The entire process can last from six to 18 months depending on the particular wireless carrier and type of device. Any delay in the acceptance process or failure to satisfy the device certification requirements would affect our ability to bring products to market and adversely impacts our results of operations and financial condition.

If we fail to adequately forecast demand for our inventory and supply needs, we could incur additional costs or experience manufacturing delays, which could reduce our gross margin or cause us to delay or even lose sales.

Because our production volumes are based on a forecast of channel partner demand rather than purchase commitments from our major customers, there is a risk that our forecasts could be inaccurate and that we will be unable to sell our products at the volumes and prices we expect, which may result in excess inventory. We provide, and will continue to provide, forecasts of our demand to our third-party suppliers prior to the scheduled delivery of products to our channel partners. If we overestimate our requirements, our contract manufacturers may have excess component inventory, which could increase our costs. If we underestimate our requirements, our contract manufacturers may have inadequate component inventory, which could interrupt the manufacturing of our products and result in delays in shipments and revenues or even lost sales, or could incur unplanned overtime costs to meet our requirements, resulting in significant cost increases. For example, certain materials and components used to manufacture our products may reach end of life during any of our product’s life cycles, following which suppliers no longer provide such expired materials and components. This would require us to either source and qualify an alternative component, which could require a re-certification of the device by the wireless carriers and/or regulatory agencies, or forecast product demand for a final purchase of such materials and components that may reach end of life to ensure that we have sufficient product inventory through a product’s life cycle. If we overestimate forecasted demand, we would hold excess end-of-life materials and components resulting in increased costs. If we underestimate forecasted demand, we could experience delays in shipments and loss of revenues.

In addition, if we underestimate our requirements and the applicable supplier becomes insolvent or is no longer able to timely supply our needs in a cost-efficient manner or at all, we may be required to acquire components, which may need to be customized for our products, from alternative suppliers, including at significantly higher costs. For example, in 2018, one of our suppliers became insolvent and ceased all production, requiring us to seek alternative supply of complex components in a very short time frame. If we cannot source alternative suppliers and/or alternative components, we may suffer delays in shipments or lost sales. Similarly, credit constraints at our suppliers could require us to accelerate payment of our accounts payable, impacting our cash flow. Further, lead times for materials and components that we order vary significantly and depend on factors such as the specific supplier, contract terms, customization needed for any particular component and demand for each component at a given time. Any such failure to accurately forecast demand and manufacturing and supply requirements, and any need to obtain alternative supply sources, could materially harm our business, results of operations and financial condition.

29

We may not be able to continue to develop solutions to address user needs effectively in an industry characterized by ongoing change and rapid technological advances.

To be successful, we must adapt to rapidly changing technological and application needs by continually improving our products, as well as introducing new products and services, to address user demands.

Our industry is characterized by:

Future success will depend on our ability to effectively and economically adapt in this evolving environment. We could incur substantial costs if we must modify our business to adapt to these changes, and may even be unable to adapt to these changes.

In the three months ended March 31, 2019 and 2018, approximately 82% and 77% of our revenues, respectively, were derived from our top five customers. We expect our revenues to continue to be heavily concentrated among our top customers, and the loss of, or significant reduction in orders from, any of these customers could significantly reduce our revenues and adversely impact our operating results.

Historically, our revenues have been concentrated among a very small number of customers. In the three months ended March 31, 2019 and 2018, our top five wireless carriers customers accounted for approximately 82% and 77% of our revenues, respectively. In 2018, three of the four largest U.S. wireless carriers, and the three largest Canadian wireless carriers, began stocking our entire next generation product portfolio for the first time in our history following their certification of our products, resulting in significant revenue concentration among these few carriers. In addition to the certification and stocking of our products by these wireless carriers, revenue increased among such wireless carriers as a result of increases in awareness of our brand among end users and end customers over the past several years, new product launches and an increased focus by carriers such as AT&T and Verizon on dedicated public safety networks, including FirstNet. We expect our revenues to remain heavily concentrated among these top wireless carriers, and we will be substantially dependent on these wireless carriers continuing to purchase and promote our products to their sales channels as well as customer demand for devices and services from these wireless carriers (factors over which we do not have any control). The loss of one or more of these significant customers, or reduced demand or purchases from these significant customers, would result in significant harm to our revenues and results of operation, and our growth could be limited.

The markets for our devices and related accessories may not develop as quickly as we expect, or may not develop at all.

Our future success is substantially dependent upon continued adoption of devices and related accessories in the industrial enterprise and public sector markets, including the transition from LMR and PTT, to smartphone and LTE networks. These market developments and transitions may take longer than we expect or may not occur at all, and may not be as widespread as we expect. If the market does not develop as we expect, our business, operating results and financial condition would be significantly harmed.

Our dependence on third-party suppliers for key components of our products could delay shipment of our products and reduce our sales.

We depend on certain suppliers for the delivery of components used in the assembly of our products, including machined parts, injection molded plastic parts, printed circuit boards and other miscellaneous custom parts for our products. Our reliance on third-party suppliers creates risks related to our potential inability to obtain an adequate supply of components and reduced control over pricing and timing of delivery of components. In particular, we have little to no control over the prices at which our suppliers sell materials and components to us. Certain supplies of our components are available only from a single source or limited sources and we may not be able to diversify sources in a timely manner. We have experienced shortages in the past that have negatively impacted our results of operations and may experience such shortages in the future. For example, in 2018, we experienced a shortage in supply of a camera part from one of our suppliers for our XP8 phone, which resulted in delays in delivery of completed XP8 phones to certain of our channel partners.

30

We also do not have long-term supply agreements with any of our suppliers. Our current contracts with certain suppliers may be canceled or not extended by such suppliers and, therefore, do not afford us with sufficient protection against a reduction or interruption in supplies. Moreover, in the event any of these suppliers breach their contracts with us, our legal remedies associated with such a breach may be insufficient to compensate us for any damages we may suffer.

Any interruption of supply for any material components of our products, or inability to obtain required components from our third-party suppliers, could significantly delay the production and shipment of our products and harm our revenues, profitability and financial condition.

Our future success is dependent on our ability to create independent brand awareness for our company and products with end customers, and our inability to achieve such brand awareness could limit our prospects.

We depend on a small number of wireless carriers to distribute our products. While we intend to ramp up direct marketing and end-customer brand awareness initiatives in the future, our sales and marketing efforts have historically been predominantly focused on channel partners. As such, our operating expenses related to end-customer marketing efforts have historically been very small, representing less than 1.0% of our total sales and marketing expenses during the three months ended March 31, 2019, and for the fiscal year 2018. To increase end-customer brand awareness, we intend to develop sales tools for key verticals within are target markets, increase usage of social media and expand product training efforts, among other things. As a result, we expect our sales and marketing expenses to increase in the future, primarily from increased sales personnel expenses, which will require us to cost-efficiently ramp up our sales and marketing capabilities and effectively target end customers. However, there can be no assurance that we will successfully increase our brand awareness or do so in a cost-efficient manner while maintaining market share within our existing sales channels. Our failure to establish stand-alone brand awareness with end customers of our products will leave us vulnerable to the marketing and selling success of others, including our channel partners, and these developments could have an adverse impact on our prospects. If we are unable to significantly increase the awareness of our brand and solutions with end customers in a cost-efficient manner, we will remain significantly dependent on our channel partners for sales of our products, and our business, financial condition and results of operations could be adversely impacted.

We are dependent on the continued services and performance of a concentrated group of senior management and other key personnel, the loss of any of whom could adversely impact our business.

Our future success depends in large part on the continued contributions of a concentrated group of senior management and other key personnel. In particular, the leadership of key management personnel is critical to the successful management of our company, the development of our solutions and our strategic direction. We also depend on the contributions of key technical personnel.

We maintain “key person” insurance only for our Chief Executive Officer and do not maintain such insurance for any other member of our senior management team or any of our other key employees. Our senior management and key personnel are all employed on an at-will basis, which means that they could terminate their employment with us at any time, for any reason and without notice. The loss of any of our key personnel could significantly delay or prevent the achievement of our development and strategic objectives and harm our business.

We compete in a rapidly evolving market, and the failure to respond quickly and effectively to changing market requirements could cause our business and operating results to decline.

The mobile device market is characterized by rapidly changing technology, changing customer needs, evolving industry standards and frequent introductions of new products and services. In order to deliver a competitive mobile device, our solutions must be capable of operating in an increasingly complex network environment. As new wireless phones are introduced and standards in the mobile device market evolve, we may be required to modify our phones and services to make them compatible with these new products and standards. Likewise, if our competitors introduce new devices and services that compete with ours, we may be required to reposition our solutions or introduce new phones and solutions in response to such competitive pressure. We may not be successful in modifying our current phones or introducing new ones in a timely or appropriately responsive manner, or at all. If we fail to address these changes successfully, our business and operating results could be significantly harmed.

If dedicated public safety LTE networks are not deployed at the rate we anticipate or at all, demand for our solutions may not grow as expected.

A key part of our strategy is to further expand the use of our solutions over dedicated LTE networks in the public safety market. If the deployment of dedicated LTE networks is delayed or such networks are not adopted at the rate we anticipate, demand for our solutions may not develop as we anticipate, which would have a negative effect on our revenues.

31

If we are unable to sell our solutions into new markets, our revenues may not grow.

Any new market into which we attempt to sell our solutions may not be receptive. Our ability to penetrate new markets depends on the quality of our solutions, the continued adoption of our public safety solution by first responders, the perceived value of our solutions as a risk management tool and our ability to design our solutions to meet the demands of our customers. If the markets for our solutions do not develop as we expect, our revenues may not grow.

Our ability to successfully face these challenges depends on several factors, including increasing the awareness of our solutions and their benefits, the effectiveness of our marketing programs, the costs of our solutions, our ability to attract, retain and effectively train sales and marketing personnel, and our ability to develop relationships with wireless carriers and other partners. If we are unsuccessful in developing and marketing our solutions into new markets, new markets for our solutions might not develop or might develop more slowly than we expect, either of which would harm our revenues and growth prospects.

If we are unable to attract, integrate and retain additional qualified personnel, including top technical talent, our business could be adversely impacted.

Our future success depends in part on our ability to identify, attract, integrate and retain highly skilled technical, managerial, sales and other personnel. We face intense competition for qualified individuals from numerous other companies, including other software and technology companies, many of whom have greater financial and other resources than we do. Some of these characteristics may be more appealing to high-quality candidates than those we have to offer. In addition, new hires often require significant training and, in many cases, take significant time before they achieve full productivity. We may incur significant costs to attract and retain qualified personnel, including significant expenditures related to salaries and benefits and compensation expenses related to equity awards, and we may lose new employees to our competitors or other companies before we realize the benefit of our investment in recruiting and training them. Moreover, new employees may not be or become as productive as we expect, as we may face challenges in adequately or appropriately integrating them into our workforce and culture. If we are unable to attract, integrate and retain suitably qualified individuals who are capable of meeting our growing technical, operational and managerial requirements on a timely basis or at all, our business will be adversely impacted.

Volatility or lack of positive performance in our stock price may also affect our ability to attract and retain our key employees. Many of our senior management personnel and other key employees have become, or will soon become, vested in a substantial amount of stock or stock options. Employees may be more likely to leave us if the shares they own or the shares underlying their vested options have significantly appreciated in value relative to the original purchase prices of the shares or the exercise prices of the options, or, conversely, if the exercise prices of the options that they hold are significantly above the market price of our common stock. If we are unable to appropriately incentivize and retain our employees through equity compensation, or if we need to increase our compensation expenses in order to appropriately incentivize and retain our employees, our business, operating results and financial condition would be adversely impacted.

Our existing IT systems may not be adequate to manage our growth, and our implementation of updated IT systems could result in significant disruptions to our operations.

Our existing IT systems may be inadequate to manage our growth, and we are planning to implement various upgrades to our enterprise resource planning, or ERP, systems, as well as other complementary IT systems, over the next several years. Implementation of these solutions and systems is highly dependent on coordination of numerous software and system providers and internal business teams. The interdependence of these solutions and systems is a significant risk to the successful completion of the initiatives and the failure of any one system could have a significant adverse impact on the implementation of our overall IT infrastructure. We may experience difficulties as we transition to these new or upgraded systems and processes, including loss or corruption of data, delayed shipments, decreases in productivity as our personnel and third-party providers implement and become familiar with new systems, increased costs and lost revenues.

In addition, transitioning to these new systems requires significant capital investments and personnel resources. Difficulties in implementing new or upgraded information systems or significant system failures could disrupt our operations and have a significant adverse impact on our capital resources, financial condition, results of operations or cash flows. Implementation of this new IT infrastructure has a significant impact on our business processes and information systems across a significant portion of our operations. As a result, we will be undergoing significant changes in our operational processes and internal controls as our implementation progresses, which in turn will require significant change management, including recruiting and training of qualified personnel. If we are unable to successfully manage these changes as we implement these systems, including harmonizing our systems, data, processes and reporting analytics, our ability to conduct, manage and control routine business functions could be negatively affected and significant disruptions to our business could occur. In addition, we could incur material unanticipated expenses, including additional costs of implementation or costs of conducting business. These risks could result in significant business disruptions or divert management’s attention from key strategic initiatives and have a significant adverse impact on our capital resources, financial condition and results of operations.

The application development ecosystem supporting our devices and related accessories is new and evolving.

The application development ecosystem supporting our devices and related accessories is new and evolving. Specifically, the number of application developers in the ecosystem supporting our devices and accessories is small. If the market or the application development ecosystem does not develop, timely or at all, demand for our products may be limited, and our business and results of operations will be significantly harmed.

Our business is difficult to evaluate because we have a limited operating history in our markets.

We have a limited operating history based on which you can evaluate our present business and future prospects. For example, in March 2018, we launched our XP5s and XP8 phones in the public safety market and also have limited operating history in the industrial enterprise market. Because of this limited operating history, we face challenges in predicting our business and evaluating its prospects. These challenges present risks and uncertainties relating to our ability to implement our business plan successfully. Our prospects must be considered in light of the risks, expenses and difficulties frequently encountered by newly-public companies that have recently launched a new product into a new market. If we are unsuccessful in addressing these risks and uncertainties, our business, results of operations and financial condition will be significantly harmed.

The impact of potential changes in customs, tariffs, and trade policies in the United States and the potential corresponding actions by other countries, including recent trade initiatives announced by the U.S. presidential administration against China, in which we do business could adversely impact our financial performance.

The U.S. government has made proposals that are intended to address trade imbalances, which include encouraging increased production in the United States. These proposals could result in increased customs duties and tariffs, and the renegotiation of some U.S. trade agreements. We import a significant percentage of our products into the United States, and an increase in customs duties and tariffs with respect to these imports could negatively impact our financial performance. If such customs duties and tariffs are implemented, it also may cause U.S. trading partners to take actions with respect to U.S. imports or U.S. investment activities in their respective countries. Any potential changes in trade policies in the United States and the potential corresponding actions by other countries in which we do business could adversely impact our financial performance. Given the level of uncertainty over which provisions will be enacted, we cannot predict with certainty the impact of the proposals.

For example, in 2018, the U.S. presidential administration and Chinese government imposed significant tariffs on exports between the two countries. This evolving policy dispute between China and the United States is likely to have significant impact on the industries in which we participate, directly and indirectly, and no assurance can be given that any individual customer or significant groups of companies or a particular industry, will not be adversely impacted by any governmental actions taken by either China or the United States. In addition, we manufacture our mobile phones at our facility in Shenzhen, China, which could result in significant additional costs to us when shipping our products to various customers in the United States. It is not possible to predict with any certainty the outcome of the trade dispute between the United States and China, and prolonged or increased tariffs on imports from China to the United States would adversely impact our business, results of operations and financial condition.

Operating outside of the United States presents specific risks to our business, and we have substantial operations outside of the United States.

Most of our employee base and operations are located outside the United States, primarily in China and India. Most of our software development, third-party contract manufacturing, and product assembly operations are conducted outside the United States.

Risks associated with operations outside the United States include:
