United States and Canada, who then resell our products in conjunction with network services to end customers. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our first mobile device was introduced and
began shipping in low volumes in 2006, primarily in Europe, and in increasing volumes in 2012 in Canada through Bell. In late 2012, we first shipped to U.S. wireless carriers, AT&amp;T and Sprint, but between 2012 and 2017, we had (i)&nbsp;only one
or two mobile phones in our product portfolio being sold at any one time, (ii)&nbsp;only a handful of wireless carriers selling such phones and (iii)&nbsp;such phones being sold generally as a <FONT STYLE="white-space:nowrap">non-stocked</FONT>
product. In 2018, three of the four largest U.S. wireless carriers and the three largest Canadian wireless carriers certified certain of our products and decided to stock our entire next generation product portfolio, for the first time in our
history, resulting in our revenues increasing by more than 100% from the year ended December&nbsp;31, 2017 to the year ended December&nbsp;31, 2019. Revenues have decreased from $135.7&nbsp;million for the year ended December&nbsp;31, 2018 to
$116.3&nbsp;million for the year ended December&nbsp;31, 2019. In 2019, we sold approximately 327,000 mobile phones to wireless carriers with approximately 36%, 31% and 18% sold to AT&amp;T, Sprint and Verizon, respectively, compared to a total of
approximately 287,500 to wireless carriers in 2018. In addition to acceptance by these large wireless carriers of our product portfolio, expanded adoption of our mobile phones was driven by increases in awareness over the past several years
following sales and marketing efforts directed at wireless carriers, new product launches and the increased focus by carriers, such as AT&amp;T and Verizon on dedicated public safety networks, including FirstNet. We expect to continue unit sales
volumes with these wireless carriers and anticipate launching additional products starting in 2020 following customization and certification processes. In March 2019 and April 2019, we launched commercial sales of our XP3 mobile phone on the Sprint
network and AT&amp;T network (including FirstNet), respectively, in each case following technical acceptance by the applicable wireless carrier. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">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 year ended December&nbsp;31, 2019, approximately 87% of our revenues came from this channel and 66% came from our
top four channel partner customers. For the year ended December&nbsp;31, 2019, our smartphones accounted for approximately 50% of our revenues and our feature phones accounted for approximately 45% of our revenues. To help control and manage the
quality, cost and reliability of our supply chain, we directly manage the procurement of all final assembly materials used in our products, which include LCDs, housings, camera modules and antennas. In addition, we complete the final assembly of our
devices in our Shenzhen, China facility. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">To continue to develop differentiated products to attract and retain customers, we have made significant
investments in research and development. While the hardware design of our devices remains generally the same for all wireless carriers, each product must be configured specifically to conform to the requirements of each carrier&#146;s network,

resulting in higher development expenses as the number of wireless carriers we sell through increases. In addition to the unique configurations, we must go through a technical acceptance process
for each device at each wireless carrier before it can be stocked. The acceptance process for each device at each wireless carrier has historically cost up to $1.2&nbsp;million. Since this task tends to be cyclical in nature, we employ third- party

the Company accrued $0.7&nbsp;million in aggregate restructuring charges related to <FONT STYLE="white-space:nowrap">one-time</FONT> termination severance payments and other employee-related costs. $0.2&nbsp;million of the cash payments related to
the personnel-related restructuring charges were paid during the second half of 2019, with the remaining $0.5&nbsp;million to be paid by the second quarter of 2020.&nbsp;The Company may also incur additional costs not currently contemplated due to

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">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&#146;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 certified to be stocked at each carrier. The approval process for each device for each carrier has historically cost between <FONT STYLE="white-space:nowrap">$1-2</FONT> </P>

million. Prior to commencement of development of a product for certification, we generally do not receive any purchase orders or commitments. Following a carrier&#146;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. </P>

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,
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 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. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Seasonality and New Product
Introduction </I></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">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.&nbsp;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. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Components of Our Results of Operations </B></P>

customer receives the products sold. Any discounts, marketing development funds, product returns or other revenue reductions are treated as offsets to revenues, which is presented on a net basis. We have also historically entered into customer
agreements with channel partners that include a combination of products and <FONT STYLE="white-space:nowrap">non-recurring</FONT> engineering services, or NRE services. When a customer agreement includes NRE services which involve significant design
modification and customization of the product software that is essential to the functionality of the hardware, revenues are also recognized according to the contractual milestones in the agreements under ASC 605 or when or as control transfers to
the customer under ASC 606. If a milestone is deemed <FONT STYLE="white-space:nowrap">non-substantive,</FONT> we defer, if applicable, and recognize such <FONT STYLE="white-space:nowrap">non-substantive</FONT> milestones over the estimated period of
performance applicable to each agreement on a straight-line basis, as appropriate. All of our revenues are derived from a single segment. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company
recognizes revenue primarily from the sale of products, including our mobile phones and accessories, and the majority of the Company&#146;s contracts include only one performance obligation, namely the delivery of product. A performance obligation
is a commitment in a contract to transfer a distinct good or service to the customer and is defined as the unit of account for revenue recognition under ASC 606. The Company also recognizes revenue from other contracts that may include a combination
of products and NRE services or from the provision of solely NRE services. Where there is a combination of products and NRE services, the Company accounts for the commitments as individual performance obligations if they are both capable of being
distinct and distinct within the context of the contract. </P>

to purchase from us any minimum number of products. However, while our channel partners provide us with demand forecasts under these sales arrangements, 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). Our sales arrangements also generally include technical performance standards for our mobile phones and accessories sold, which vary by
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

bases of assets and liabilities and the tax effects of operating loss and credit carryforwards using the enacted tax rates expected to apply in the periods of expected settlement. In addition, this method requires a valuation allowance against net
deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. </P>

14.3%, to $116.3&nbsp;million compared to $135.7&nbsp;million for the year ended December&nbsp;31, 2018.&nbsp;The decrease in net revenues was primarily attributable to a lower overall average selling price as a result of the change in product mix
in 2019 compared to 2018 along with a significant decrease in professional service fees from $5.0&nbsp;million in 2018 to $0.4&nbsp;million in 2019. </P>

29.7% of revenues, from $48.1&nbsp;million, or 35.4% of revenues for the year ended December&nbsp;31, 2018.&nbsp;This decrease was primarily attributable to lower revenues related to a lower average sales price and a
<FONT STYLE="white-space:nowrap">one-time</FONT> reserve adjustment relating to the aging of materials and finished goods, losses resulting from minimum purchase commitment of $3.1&nbsp;million and the amortization of NRE expenses of
$1.5&nbsp;million as a result of the adoption of ACS 606. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Research and development.</I>&nbsp;Research and development expenses for the year ended

headcount related expenses, prior to restructuring, a $1.2&nbsp;million increase in costs associated with the XP3 product launch, a $0.8&nbsp;million increase in consulting, a $0.3&nbsp;million increase in travel expense and a $0.2&nbsp;million
increase for IDC office rent, partially offset by $2.7&nbsp;million for the ACS 606 adjustment of capitalized fulfillment costs now flowing through cost of revenues. </P>

$13.9&nbsp;million compared to $12.2&nbsp;million for the year ended December&nbsp;31, 2018.&nbsp;These increases were primarily attributable to a $0.7&nbsp;million increase in employee headcount, prior to restructuring, a $0.7&nbsp;million increase
related to the expansion of our customer support department, and $0.3&nbsp;million of related stock compensation expense. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>General and
administrative</I>.&nbsp;General and administrative expenses for the year ended December&nbsp;31, 2019 increased by $9.0&nbsp;million, or 124.1% to $16.2&nbsp;million compared to $7.2&nbsp;million for the year ended December&nbsp;31,
2018.&nbsp;These expenses increased primarily due to a $5.1&nbsp;million increase of stock compensation in connection with the IPO for the Chief Executive Officer and Chief Financial Officer, a $1.1&nbsp;million increase of directors and officers
insurance, a $0.9&nbsp;million increase in legal fees, a $0.8&nbsp;million increase of employee compensation and hiring of new consultants, $0.7&nbsp;million of increased accounting fees, and a $0.5&nbsp;million increase for office rent.</P>

Convertible Note issued by the Company pursuant to the Subordinated Term Loan and Security agreement (the &#147;Riley Loan Agreement&#148;), we have borrowed an aggregate principal amount of $12.0&nbsp;million 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&nbsp;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 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

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&nbsp;million
following prepayment.&nbsp;Following prepayment, the outstanding principal balance fell below the $10.0&nbsp;million threshold and we paid a minimal prepayment fee. We have classified the debt as a current liability from a long-term liability based
on the occurrence of a material adverse change in our business, however B. Riley Principal Investments LLC has not commenced enforcement of its rights thereunder.&nbsp;Upon the occurrence and during the continuance of an&nbsp;event of default under
the Riley Loan Agreement, B. Riley Principal Investments has the option, among other things, to accelerate the debt and foreclose upon the assets pledged as collateral, any of which could severely affect our liquidity and significantly harm our
business. In addition, we are unable to borrow under the EWB facility during the continuance of an event of default thereunder or under the Riley Loan Agreement, which could severely affect our liquidity and significantly harm our business. </P>

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 EWB 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

are otherwise subject to the terms and conditions of the EWB Loan Agreement.&nbsp;As of 2019, we were not in compliance with one of the financial covenants, specifically the fixed charge coverage ratio, however, EWB waived such noncompliance in

been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions for the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Our
estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that
are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and any such differences may be material.&nbsp;The worldwide spread of the COVID-19 virus is expected to result in
a global slowdown of economic activity which is likely to decrease demand for a broad variety of goods and services, including from our customers, while also disrupting sales channels and marketing activities for an unknown period of time until the
disease is contained. We expect this to have a negative impact on our sales and our results of operations, the size and duration of which we are currently unable to predict. In preparing our consolidated financial statements in accordance with GAAP,
we are required to make estimates, assumptions and judgments that affect the amounts reported in our financial statements and the accompanying disclosures. Estimates and assumptions about future events and their effects cannot be determined with
certainty and therefore require the exercise of judgment. As of the date of issuance of these financial&nbsp;statements, we are not aware of any specific event or circumstance that would require us to update our estimates, judgments or revise the
carrying value of our assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known. Actual results could

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Historically, for all periods prior to this initial public offering, the fair values of the shares of our common stock underlying our share-based awards were
estimated on each grant date by our board of directors. In order to determine the fair value of our common stock underlying option grants, our board of directors considered, among other things, valuations of our common stock prepared by an
independent third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accountants Practice Guide,<I></I><I>&nbsp;Valuation of Privately-Held-Company Equity Securities Issued as
Compensation</I>. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The fair value of our common stock was estimated by first estimating our aggregate implied equity value using a weighting of discounted
cash flows method (income approach) and comparable public companies method (market approach). Prior to the conversion of all of our outstanding preferred stock into common stock, an option pricing model, or OPM, was used to allocate the total equity
value to the different classes of equity according to their rights and privileges. To apply the OPM, we estimated the expected time to liquidity, volatility and risk-free rate. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Given the absence of a public trading market for our common stock, our board of directors exercised their judgment and considered a number of objective and
subjective factors to determine the best estimate of the fair value of our common stock, including valuations performed by an independent third party, developments in our operations, sales of preferred stock, the prices, rights, preferences and
privileges of our preferred stock relative to the common stock, actual operating results and financial performance and capital resources, the conditions in the our industry and the economy and capital markets in general, the stock price performance
and volatility of comparable public companies, the likelihood of achieving a liquidity event for shares of our common stock underlying these stock options, such as an initial public offering or sale of our company, and the lack of liquidity of our
common stock, among other factors. After the closing of this offering, our board of directors will determine the fair value of each share of underlying common stock based on the closing price of our common stock as reported on the date of the grant.
Our board of directors intended all options granted to be exercisable at a price per share not less than the per share fair value of our common stock underlying those options on the grant date. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Provision for Income Taxes </I></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The provision for income
taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and
liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to
be realized or settled. We record a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in multiple tax jurisdictions. We may
be periodically reviewed by domestic and foreign tax authorities regarding the amount of taxes due. These reviews may include questions regarding the timing and amount of deductions and the allocation of income among various tax jurisdictions. In
evaluating the exposure associated with various filing positions, we record estimated reserves when it is more likely than not that an uncertain tax position will not be sustained upon examination by a taxing authority. Such estimates are subject to
change. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Inventory Valuation </I></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We report inventories
at the lower of cost or net realizable value, in accordance with the adoption of Accounting Standards Update Codification 330,<I>&nbsp;Inventory (Topic 330): Simplifying the Measurement of Inventory</I>. Cost is determined using <FONT
STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">a&nbsp;first-in,&nbsp;first-out&nbsp;method,</FONT></FONT> or FIFO, and includes materials, labor, shipping and manufacturing overhead related to the purchase and production of inventories.

systems during the warranty period. We account for the estimated warranty cost as a charge to cost of revenues when revenue is recognized. The estimated warranty cost is based on historical product performance and field expenses. We update this

the November 2018 conversion of all our preferred stock into common stock, we accounted for our freestanding warrants to purchase shares of our convertible preferred stock as liabilities at fair value upon issuance primarily because the shares
underlying the warrants contain contingent redemption features outside our control. The warrants were subject <FONT STYLE="white-space:nowrap">to&nbsp;re-measurement&nbsp;at</FONT> each balance sheet date with any change in fair value being
recognized as the change in fair value of warrant liability. Subsequent to this conversion, the remaining convertible preferred stock warrants became warrants to purchase common stock and the related liability was reclassified to <FONT
