NOTES TO CONDENSED 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

Basis of presentation and preparation

The condensed consolidated financial statements include the accounts of Sonim Technologies, Inc. and its wholly owned subsidiaries (collectively “Sonim” or the “Company”). Intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The preparation of these condensed consolidated financial statements and accompanying notes in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from those estimates. Certain prior period amounts in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and accompanying notes included in its Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”).

On September 15, 2021, the Company effected a 1-for-10 stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock on that date. Additionally, the number of shares of the Company’s common stock subject to outstanding stock options and restricted stock units, the exercise price of all of its outstanding stock options, and the number of shares of common stock reserved for future issuance pursuant to its equity compensation plans were adjusted proportionately in connection with the Reverse Stock Split. The number of authorized shares of common stock under the Company’s Amended and Restated Certificate of Incorporation and the par value per share of its common stock were unchanged. All historical share and per share amounts presented herein have been adjusted retrospectively to reflect these changes.

Liquidity and Going Concern

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with GAAP.

Pursuant to the requirements of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

The Company had cash and cash equivalents of $10,187 and an accumulated deficit of $223,083 at September 30, 2021, and a net loss of $10,939 for the quarter ended September 30, 2021. Since inception, the Company has been developing ultra-rugged mobile phones and accessories designed specifically for task workers physically engaged in their work environments, often in mission-critical roles. The Company’s ability to continue as a going concern is dependent on its ability to complete ongoing and future development of its ultra-rugged mobile phones and accessories, continue commercial scale production and sell its products. The Company believes that its current level of cash and cash equivalents are not sufficient to fund commercial scale production and product sales. These conditions raise substantial doubt regarding the Company’s ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements.

To alleviate these conditions, management is currently evaluating various funding alternatives and may seek to raise additional funds through the issuance of equity, mezzanine or debt securities, through arrangements with strategic or investment partners with greater resources or access to funds or through obtaining credit from government or financial institutions. As the Company seeks additional sources of financing, there can be no assurance that such financing would be available to the Company on favorable terms or at all. The Company’s ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to the Company and its industry.

New accounting pronouncements:

Pronouncements adopted in 2021:

In December 2019, FASB issued Accounting Standards Update (ASU) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes by removing certain exceptions to the general principles of ASC 740 in order to reduce cost and complexity of its application.  The ASU removes the exception related to the incremental approach for intra-period tax allocation, as well as two exceptions related to account for outside basis differences of equity method investments and foreign subsidiaries. This guidance is effective for fiscal years beginning after December 31, 2021, with early adoption permitted. The Company adopted ASU 2019-12 on January 1, 2021. The adoption of ASU 2019-12 did not have an impact on the Company’s condensed consolidated financial statements.

Pronouncements not yet adopted:

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 to control the use of the given asset assumed under the lease. As an emerging growth company, the Company has elected to adopt the standard based on nonpublic business entities implementation dates for annual reporting periods beginning after December 15, 2021. The Company is currently evaluating this new standard and the impact it will have on its condensed consolidated financial statements, information technology systems, process, and internal controls.

NOTE 2 —Revenue recognition

The Company recognizes revenue primarily from the sale of products, including its mobile phones, barcode scanners and accessories, and the majority of the Company’s contracts include only one performance obligation, namely the delivery of product. A performance obligation is a promise 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, Revenue from Contracts with Customers. The Company also recognizes revenue from other contracts that may include a combination of products and non-recurring engineering (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 promises as individual performance obligations if they are concluded as distinct. Performance obligations are considered distinct if they are both capable of being distinct and distinct within the context of the contract. In determining whether performance obligations meet the criteria for being distinct, the Company considers a number of factors, such as the degree of interrelation and interdependence between obligations, and whether or not the good or service significantly modifies or transforms another good or service in the contract. During the three and nine months ended September 30, 2021, and 2020, the Company did not have any contracts in which the products and NRE services were concluded to be a single performance obligation. In certain cases, the Company may offer tiered pricing based on volumes purchased for specific products. To date, all tiered pricing provisions have fallen into observable ranges of pricing to existing customers, thus, not resulting in any material right which could be concluded as its own performance obligation. In addition, the Company does not offer material post-contract support services to its customers.

Net revenue for an individual contract is recognized at the related transaction price, which is the amount the Company expects to be entitled to in exchange for transferring the goods and/or services. The transaction price for product sales is calculated as the product selling price, net of variable consideration, which may include estimates for marketing development funds, sales incentives, and price protection and stock rotation rights. The Company records reductions to net revenues related to future product returns based on the Company’s expectations and historical experience. Typically, variable consideration does not need to be constrained as estimates are based on specific contract terms. However, the Company continues to assess variable consideration estimates such that it is probable that a significant reversal of revenue will not occur. The transaction price for a contract with multiple performance obligations is allocated to the separate performance obligations on a relative standalone selling price basis. Standalone selling prices for products are determined based on the prices charged to customers, which are directly observable. Standalone selling price of the professional services are mostly based on time and materials. The Company determines its estimates of variable consideration based on historical collection experience with similar payor classes, aged accounts receivable by payor class, terms of payment agreements, correspondence from payors related to revenue audits or reviews, the Company’s historical settlement activity of audited and reviewed claims and current economic conditions using the portfolio approach. Revenue is recognized only to the extent that it is probable that a significant reversal of the cumulative amount recognized will not occur in future periods.

Revenue is then recognized for each distinct performance obligation as control is transferred to the customer. Revenue attributable to hardware is recognized at the time control of the product transfers to the customer. Control is generally transferred when the Company has a present right to payment and title and the significant risks and rewards of ownership of products or services are transferred to its

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

customers. For most of the Company’s revenue attributable to hardware, control transfers when products are shipped. Revenue attributable to professional services is recognized as the Company performs the professional services to the customer.

Disaggregation of revenue

The following table presents the Company’s net revenue disaggregated by product category:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2021		2020		2021		2020
Smartphones	$	2,800	$	5,684	$	11,115	$	18,040

Scanners		3	—			1,094	—
Accessories/Other		246		386	695			2,058
	$	14,445	$	14,393	$	38,639	$	48,157

Shipping and handling costs

The Company has elected to account for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products.

Distributor returns allowance

The Company records reductions to net revenues related to future distributor product returns based on the Company’s expectation. The Company had allowances for distributor product returns totaling approximately $300 as of September 30, 2021.

Contract costs

Applying the practical expedient, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred when the amortization period of the assets that otherwise would have been recognized is one year or less. These costs are included in sales and marketing  expenses.

The non-recurring costs associated with design and development of new products for technical approval, represent costs to fulfill a contract pursuant to ASC 340-40 Other Assets and Deferred Costs. Accordingly, the Company capitalizes these non-recurring engineering costs and amortizes such costs over the estimated period of time over which they are expected to be recovered, which is typically 4 years, the estimated life of a particular model phone.

The total capitalized costs to fulfill a contract is primarily associated with Company’s introduction of the XP8 model phone and now the XP3 Plus model feature phone. As of September 30, 2021, and December 31, 2020, the total costs to fulfill a contract included in other assets were $2,684 and $2,889, respectively.

Contract balances

The Company records accounts receivable when it has an unconditional right to consideration. As of September 30, 2021, the Company did not have a contract receivable balance. Contract liabilities are recorded when cash payments are received or due in advance of performance. Contract liabilities consist of advance payments and deferred revenue, where the Company has unsatisfied performance obligations.

NOTE 3 —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:

• Quoted market prices for similar assets or liabilities in active markets;

• Quoted prices for identical or similar assets or liabilities in inactive markets;

• Inputs other than quoted prices that are observable for the asset or liability;

• Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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 assets 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 September 30, 2021, and December 31, 2020.

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

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 at fair value:

NOTE 8 —Stockholders’ Equity

On September 15, 2021, the Company effected a 1-for-10 stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock on that date. Additionally, the number of shares of the Company’s common stock subject to outstanding stock options and restricted stock units, the exercise price of all of its outstanding stock options, and the number of shares of common stock reserved for future issuance pursuant to its equity compensation plans were adjusted proportionately in connection with the Reverse Stock Split. The number of authorized shares of common stock under the Company’s Amended and Restated Certificate of Incorporation and the par value per share of its common stock were unchanged. All historical share and per share amounts presented herein have been adjusted retrospectively to reflect these changes.

On June 30, 2021, we entered into an At Market Issuance Sales Agreement (“Sales Agreement”) with B. Riley Securities, Inc. and EF Hutton, a division of Benchmark Investments, LLC (“Sales Agents”) to sell shares of our common stock, $0.001 par value per share, having an aggregate offering price of up to $10,000, from time to time, through an “at-the-market offering” program (the “June 2021 ATM Program”). Under the terms of the Sales Agreement, we paid the Sales Agents a commission equal to 3.0% of the gross proceeds from each sale of common stock sold through it under the Sales Agreement. We exhausted this June 2021 ATM Program on July 14, 2021, selling an aggregate of 1,820,785 shares of our common stock at an average price per share of $4.59 and for net proceeds of approximately $8,363 during the three and nine months ended September 30, 2021.

On September 23, 2021, we entered into a new At Market Issuance Sales Agreement with the same B. Riley Securities, Inc., as sales agent, to sell shares of our common stock, $0.001 par value per share, having an aggregate offering price of up to $41,637 from time to time, through a new “at the market offering” program (the “ATM Program”). Under the terms of the Sales Agreement, we will pay B. Riley Securities, Inc. a commission equal to 3.0% of the gross proceeds from each sale of common stock sold through it under the Sales Agreement. From September 27, through September 30, 2021, we issued and sold an aggregate of 735,003 shares of our common stock at an average price per share of $2.69 under the ATM Program for net proceeds of approximately $1,974. All proceeds were received by September 30, 2021, with exception of $1,291, which were received by October 4, 2021. The outstanding net proceeds were classified as long term other assets since the cash was collected prior to the issuance of our financial statements, and as such, the statement of cashflows reflects $9,046 in cash collected as of September 30, 2021.

NOTE 10 —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 September 30, 2021, and 2020, the Company recorded provisions for income taxes of $90, and $150, respectively. For the nine months ended September 30, 2021, and 2020, the Company recorded provisions for income taxes $227, and $513, respectively.

NOTE 11 —Commitments and Contingencies

The terms and conditions of applicable bylaws, certificates or articles of incorporation, agreements or applicable law may obligate Sonim under certain circumstances to indemnify its current and former directors, officers or employees, and underwriters, with respect to certain of the matters described below and Sonim has been advancing legal fees and costs to certain current and former directors, officers, employees and underwriters in connection with certain matters describe below.

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 2026. Royalty expense for the three months ended September 30, 2021, and 2020 was $524 and $470, respectively. Royalty expense for the nine months ended September 30, 2021, and 2020 was $1,369 and $1,664, respectively. The Company may be required to pay additional royalties to additional patent holder and technology providers on future products.

Securities litigation—On September 20, 2019, a purported Sonim stockholder who allegedly purchased stock registered in Sonim’s initial public offering (“IPO”) filed a putative class action complaint in the Superior Court of the State of California, County of San Mateo, captioned Pearson v. Sonim Technologies, Inc., et al., Case No. 19CIV05564, on behalf of himself and others who purchased shares of Sonim registered in the IPO (the “Pearson Action”). On October 4 and 16, 2019, two additional purported class action complaints substantially similar to the Pearson Action were filed on behalf of different plaintiffs yet the same putative class of Sonim stockholders, in the same court as the Pearson Action (the “’33 Act State Court Actions”). The defendants asked the Superior court to dismiss the “33 Act State Court Actions based on the provision in the Company’s Amended and Restated Certificate of Incorporation requiring stockholders to file and litigate in federal court any claims under the Securities Act of 1933. On December 7, 2020, the Superior Court entered an order granting defendants’ motion to dismiss. On October 7, 2019, a substantially similar putative class action lawsuit was filed in the United States District Court for the Northern District of California (the “’33 Act Federal Action”). All four complaints allege violations of the Securities Act of 1933 by Sonim and certain of its current and former officers and directors for, among other things, alleged false or misleading statements and omissions in the registration statement issued in connection with the IPO, relating primarily to an alleged failure to disclose software defects in Sonim’s phones and alleged misstatements about performance characteristics of Sonim’s phones. In July 2020, the Company entered into an agreement with the Lead Plaintiff in the ‘33 Act Federal Action to settle that case on a class wide basis for $2.0 million. As a result, the Company has paid out the $2.0 million settlement as of December 31, 2020. On March 5, 2021, the court presiding over the ’33 Act Federal Action granted final approval of the settlement.

Securities and Exchange Commission Formal Order of Private Investigation: In March 2020, the Company received a voluntary document request from the SEC San Francisco Regional office, and in August 2020, the Company was informed that the SEC Staff was conducting a formal investigation into events that occurred in 2018-2019.  The Company has been cooperating in the SEC’s ongoing investigation.  In October 2021, the Company and the SEC Staff began discussions regarding a potential resolution of the investigation, Those discussions are ongoing. The Company is unable to predict the likely outcome of the investigation, including whether it can be resolved through settlement negotiations, or determine its potential impact, if any, on the Company.

Derivative litigation— On September 21, 2020, the Company, and certain of its current and former directors and officers were sued

SONIM TECHNOLOGIES, INC

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

by a stockholder on behalf of our Company in a derivative action in the United States District Court for the District of Delaware, captioned Kusiak v. Plaschke, et al., Case No 20-cv-1270-MN (“Kusiak”). The Kusiak complaint is based largely on the same underlying factual allegations as the ’33 Act Federal Action.  The defendants filed a motion to dismiss the Kusiak derivative action based on plaintiff’s failure to make a litigation demand on Sonim’s directors.   On February 1, 2021, plaintiff in Kusiak voluntarily dismissed the action without prejudice.

On February 1, 2021, the same plaintiffs’ lawyers in the Kusiak action filed a new derivative action in the United States District Court for the District of Delaware against the Company and certain of its current and former directors and officers, captioned Gupta v. Plaschke, et al., Case No. 1:21-cv-130-MN (“Gupta”). The allegations in the Gupta complaint are generally similar to those in the Kusiak action. The defendants filed a motion to dismiss the Gupta derivative action based on plaintiff’s failure to make a litigation demand on Sonim’s directors. Given the early stages of this proceeding and the limited information available, the Company cannot predict the outcome of this legal proceeding or determine its potential impact, if any, on the Company.

General litigation—The Company is involved in various other legal proceedings arising in the normal course of business. The Company does not believe that the ultimate resolution of these other matters will have a material adverse effect on its condensed consolidated financial position, results of operations, or cash flows.

The results of any future litigation cannot be predicted with certainty and, regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management time and resources and other factors.

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 (Executive Severance Arrangements) 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 in accordance to the terms of the agreements. On May 31, 2021, the Company and Tom Wilkinson agreed that he will cease serving as the Company’s Chief Executive Officer.  In connection with his departure, the Company entered into a Separation and Release Agreement with him pursuant to which he will continue to be paid his base salary of $400, the rate in effect on the effective date for a period of twelve months, subject to tax withholding and any other authorized deductions, and will continue to be eligible for the Transaction Bonus Plan until November 30, 2021.

On December 11, 2019, the Board of Directors approved the Sonim Technologies Inc. Transaction Bonus Plan (the “Plan”) that is intended to incentivize Company employees who are in a position to significantly impact the value received by the Company’s stockholders in a change of control transaction. Pursuant to the Plan, upon consummation of a change of control transaction, 10% of the consideration payable to Company stockholders, after deducting transaction expenses, will be distributed to Plan participants, including the Company’s named executive officers. The Plan has a three-year term and may be extended by the administrator of the Plan. Subject to the terms of the Plan, participants must be continuously providing services to the Company through the date of the closing of a change in control transaction to be eligible to receive a bonus thereunder, except in the event of death or disability or involuntary termination without cause as further described in Section 5(c) and 5(d) of the Plan, and payment is contingent upon delivery and non-revocation of a general release of claims. In connection with the adoption of the Plan, the Board of Directors allocated a 50% interest in the Plan to Tom Wilkinson, the Company’s former Chief Executive Officer, and a 10% interest in the Plan to Robert Tirva, the Company’s President, Chief Operating Officer and Chief Financial Officer, and 35% to 6 other key employees and consultants.

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 the three largest wireless carriers in the United States—AT&T,  T-Mobile, 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. In 2020, we announced that we would be entering the ruggedized barcode scanner business and we began shipping our first devices in March 2021.  Our barcode scanner devices, as well as our ruggedized phones and accessories, are sold through distributors in North America, South America and Europe.

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 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 and high quality, 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 certified to be stocked at such carrier. The approval process for each device for each carrier has historically cost between $1-2 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. See the risk factor entitled “We may not be able to continue to develop solutions to address user needs effectively, including our next generation products, which would materially adversely affect our liquidity and our ability to continue operations.” in this Quarterly Report on Form 10-Q for more information.

17

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, 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 also plan to continue to invest in international expansion. 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.

New Product Introduction and Seasonality

We have historically experienced lower net revenue in the quarters leading up to new product introductions, as the revenue decline of legacy products does not perfectly match the revenue ramp up of new products. 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.

Outsourced Manufacturing Partnerships

As part of our restructuring, we have shifted the majority of new product engineering to several outsourced partners. As this is a new process for us, additional risk exists in our ability to meet product development timelines required by our customers until we gain experience with these partners. In addition, these development efforts require significant cash outlays in advance  of the completion of the work. If the work is substandard, or does not meet our customers’ requirements, it is uncertain whether these expenditures can be recovered from our partners.

Recent Developments

Liquidity and Going Concern  

We had cash and cash equivalents of $10,187 and an accumulated deficit of $223,083 at September 30, 2021, and a net loss of $10,939 for the quarter ended September 30, 2021. Since inception, we have been developing ultra-rugged mobile phones and accessories designed specifically for task workers physically engaged in their work environments, often in mission-critical roles. Our ability to continue as a going concern is dependent on, among other things, our ability to complete ongoing and future development of our ultra-rugged mobile phones and accessories, continue commercial scale production and sell our products. We believe that our current level of cash and cash equivalents is not sufficient to fund commercial scale production and product sales. These conditions raise substantial doubt regarding our ability to continue as a going concern for a period of at least one year from the date of issuance of the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

To alleviate these conditions, management is currently evaluating various funding alternatives and may seek to raise additional funds through the issuance of equity, mezzanine or debt securities, through arrangements with strategic partners or through obtaining credit from government or financial institutions. As we seek additional sources of financing, there can be no assurance that such financing would be available to us on favorable terms or at all. Our ability to obtain additional financing in the debt and equity capital markets, including pursuant to our ATM Program (as defined below), is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to us and our industry. See Note 1 and risk factor entitled “Our unaudited condensed consolidated financial statements included a statement that there is a substantial doubt about our ability to continue as a going concern and a continuation of negative financial trends could result in our inability to continue as a going concern.” in this Quarterly Report on Form 10-Q for more information.

Rugged Handheld and Tablet Devices

Beginning in the three months ended March 31, 2021, we entered the rugged handheld and tablet market with our new SmartScanner products. The Sonim RS80, an Android-based tablet that is certified as Android Enterprise Recommended by Google, became available in February 2021. Additionally, we shipped the Sonim RS60, an Android-based handheld computer and LTE device that is certified as Android Enterprise Recommended by Google, during the three months ended June 30, 2021. On June 30, 2021, we announced the RT80, an Android-based tablet that differs from the RS80 by not having an integrated barcode scanner.

Next Generation Ruggedized Mobile Phones

During the nine months ended September 30, 2021, we prioritized spending on research and development of our new products, including our next generation feature phones, and we successfully launched the first product (the XP3 Plus) in the third quarter of 2021. These devices will utilize new processors for increased performance and provide expanded network support for additional and new carriers in the United States, as well as in Europe. They will also include new features and support usability requirements based on feedback from our current customers. In the nine months ended September 30, 2021, we saw strong demand for the initial ultra-rugged feature phone that launched in the third quarter of 2021, with shipments during the three months ended September 30, 2021, of approximately $4.3 million. We continue to see strong purchase order volume into the fourth quarter of 2021; such purchase orders are not binding and could be terminated at any time.

On June 29, 2021, we announced that we had secured design win awards with a leading U.S. carrier for two of our next-generation ultra-rugged phones expected to be introduced in 2022 – an upgraded feature phone with enhanced push to talk (“PTT”) capabilities, and a smartphone with 5G capabilities. The carrier design win awards were made based on the design specifications, feature set and costs provided by Sonim as part of an RFP process. We now have design win awards from the three largest U.S. carriers for new products that we began shipping as of September 30, 2021 and will continue through the third quarter of fiscal 2022. During the quarter ended September 30, 2021, we successfully launched the XP3 Plus to two major U.S. carriers. Design win awards do not obligate the carriers to purchase any devices and may be terminated at any time. In addition, such design wins will require additional capital and investment in research and development which the Company may not have access to or be able to raise.

Restructuring

At the beginning of 2021, we outsourced substantially all of our software development to a third-party and transferred 105 employees to support the ongoing work to be performed.  In connection with outsourcing our software development, we entered into an agreement of future business volume over the next three years in the amount of $7.1 million, of which we have committed that a minimum value of $3.1 million will be assured in the first year of business. We have paid $2.5 million related to this agreement during the nine months ended September 30, 2021. The remaining $0.6 million is expected to be paid during the fourth quarter of 2021.

Additionally, in the beginning of 2021, we outsourced our manufacturing work to a supply chain partner and transferred or eliminated 22 employees as part of this solution. Our worldwide employee count at September 30, 2021, was 78.

Management Changes

On May 31, 2021, Mr. Tom Wilkinson resigned from his positions and offices with Sonim, including as our Chief Executive Officer. In connection with and effective upon Mr. Wilkinson’s separation with the Company on May 31, 2021, the Board appointed Mr. Robert Tirva, the Company’s Chief Financial Officer, to the additional positions of President and Chief Operating Officer of the Company.

Nasdaq Minimum Bid Price Delinquency and Reverse Stock Split

On April 28, 2021, we received a deficiency letter from the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market, LLC (“Nasdaq”) notifying us that, for the last 30 consecutive business days, the bid price for our common stock had closed below $1.00 per share, which is the minimum closing price required to maintain continued listing on the Nasdaq Stock Market under Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Requirement”). On September 15, 2021, we effected a 1-10 reverse stock split (“Reverse Stock Split”) of our issued and outstanding shares of common stock, which increased the trading price of our common stock on Nasdaq and resulted in a change in the number of shares of our outstanding stock from 85,161,562 to 8,516,122. Additionally, the number of shares of our common stock subject to outstanding stock options and restricted stock units, the exercise price of all of our outstanding stock options, and the number of shares of common stock reserved for future issuance pursuant to our equity compensation plans were adjusted proportionately in connection with the Reverse Stock Split. The number of authorized shares of common stock under our Amended and Restated Certificate of Incorporation and the par value per share of our common stock were unchanged.

On September 30, 2021, we received a letter from the Staff notifying us that we had regained compliance with the minimum bid requirement.

19

ATM Program

On June 30, 2021, we entered into an At Market Issuance Sales Agreement with B. Riley Securities, Inc. and EF Hutton, a division of Benchmark Investments, LLC to sell shares of our common stock, $0.001 par value per share, having an aggregate offering price of up to $10,000,000, from time to time, through an “at-the-market offering” program (the “June 2021 ATM Program”). We exhausted this June 2021 ATM Program in July 14, 2021, selling an aggregate of 1,820,785 shares of our common stock at an average price per share of $4.59 and for net proceeds of approximately $8,363,250.

On September 23, 2021, we entered a new At Market Issuance Sales Agreement (the “Sales Agreement”) with B. Riley Securities, Inc. (the “Sales Agent”) to sell shares of our common stock, $0.001 par value per share, having an aggregate offering price of up to $41,636,612 from time to time, through a new “at the market offering” program (the “ATM Program”). Under the terms of the Sales Agreement, we will pay the Sales Agent a commission equal to 3.0% of the gross proceeds from each sale of common stock sold through it under the Sales Agreement. From September 27, 2021, through October 15, 2021, we issued and sold an aggregate of 7,548,186 shares of our common stock at an average price per share of $2.16 under the ATM Program for net proceeds of approximately $16.3 million. As of October 31, 2021, we had approximately $24.8 million available for future issuances under the ATM Program.

Strategic Alternatives

In August 2021, we announced that we had initiated a review of our strategic alternatives and capital market options, including both buy and sell side opportunities. This process is ongoing, and we engaged B. Riley to assist in the process. There can be no assurances that the strategic and financing alternatives process will result in the announcement or consummation of any strategic or financing transaction, or that any resulting plans or transactions will yield additional value for shareholders. See the risk factor entitled “We cannot assure you that our exploration of strategic and financing alternatives will result in a transaction and/or financing or that any such transaction or financing would be successful, and the process of exploring strategic and financing alternatives or its conclusion could adversely impact our business and our stock price” in this Quarterly Report on Form 10-Q for more information.

Results of Operations

The following tables present key components of our results of operations for the three and nine months ended September 30, 2021, compared to results for the same period in 2020:

	Three Months Ended September 30,												Nine Months Ended September 30,

Net Revenues

For the three months ended September 30, 2021, net revenues were approximately $14.4 million, as compared to net revenues of $14.4 million for the three months ended September 30, 2020. Approximately 89% of net revenues for the third quarter of 2021 was attributable to North America, Canada, and Latin America compared to approximately 91% of net revenues in the same period in 2020. Our top three customers accounted for approximately 72% of net revenues in the third quarter of 2021, and our top four customers accounted for approximately 63% of net revenues for the same period in 2020. Revenue for the three months ended September 30, 2021, was primarily driven by sales of our new XP3 Plus of $4 million which helped offset the decline in the sales of our legacy products of $3.5 million.

20

For the nine months ended September 30, 2021, net revenues were $38.6 million compared to net revenues of $48.1 million for the nine months ended September 30, 2020, a decrease of $9.5 million, or 20%. Approximately 95% of net revenue for the nine months ended September 30, 2021, was attributable to North America, Canada, and Latin America compared to approximately 94% for the nine months ended September 30, 2020. Our top three customers accounted for approximately 64% of our net revenue for the nine months ended September 30, 2021, compared to approximately 61% of net revenue for the same period in 2020. The decline in revenue for the nine months ended September 30, 2021, was primarily driven by a drop in the number of unit sales of our legacy product by 79,699, or 39% due to the aging of the existing product set, partially offset by the unit sales of the XP3 Plus of 25,380 and the unit scanner sales of 1,833.

Our customer agreements with channel partners set forth the terms pursuant to which our channel 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 currently contractually obligated to purchase from us any minimum number of products. The lack of firm purchase volume commitments makes it difficult for us to forecast customer demand. 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 open purchase orders and levy certain monetary penalties. In addition, our channel partners retain sole discretion in which of their stocked products to offer their customers.

Gross Profit

Gross profit for the three months ended September 30, 2021, was $1.8 million, as compared to $4.4 million for the three months ended September 30, 2020, a decrease of $2.6 million or 59%. The decrease in gross profit is a result of the product mix resulting in a lower average selling price along with an increase in a higher average cost decreasing gross profit by approximately $2.5 million.

Gross profit for the nine months ended September 30, 2021, was $6.9 million, as compared to $11.5 million for the nine months ended September 30, 2020, a decrease of $4.6 million or 40%. The decrease in gross profit is a result of a drop in unit sales which caused a decrease in gross profit of approximately $5.1 million. The gross profit percentage dropped as a result of product mix related to our lower margin XP3 Plus.

Operating Expenses and Net Operating Loss

Net operating loss for the three and nine months ended September 30, 2021, compared to the three and nine months ended September 30, 2020, increased by $4.6 million and $4.5 million, respectively, driven primarily by the decrease in revenues discussed above and, the decrease in gross profit margin. The increase in operating expenses of $2.0 million and $0.1 million for the three and nine months ended September 30, 2021, and 2020, respectively.

21

Operating expenses are summarized as follows:

Research and Development.

Research and development expenses for the three months ended September 30, 2021, were $5.5 million, as compared to $3.4 million for the three months ended September 30, 2020, an increase of $2.1 million, or 62%. These expenses increased primarily due to a $3.1 million increase in product development costs related to the new SmartScanner products and our next generation feature phone, partially offset by decreases in employee headcount related expenses of $0.5 million, consultant expenses of $0.3 million and other office expenses of $0.2 million.

Research and development expenses for the nine months ended September 30, 2021, were $13.8 million, as compared to $10.6 million for the nine months ended September 30, 2020, an increase of $3.2 million, or 31%. These expenses increased primarily due to a $6.1  million increase in product development costs related to the new SmartScanner products and our next generation feature phone, partially offset by a decrease in employee headcount related expenses of $2.4 million, consultant expenses of $0.3 million, depreciation expense of $0.2 million.

Sales and Marketing.

Sales and marketing expenses for the three months ended September 30, 2021, were $3.1 million, as compared to $2.9 million for the three months ended September 30, 2020, an increase of $0.2 million, or 7%. These expenses increased due to a $0.9 million increase in marketing related expenses, offset by decreases in headcount related expenses of $0.7 million.

Sales and marketing expenses for the nine months ended September 30, 2021, were $7.5 million, as compared to a $8.6 million for the nine months ended September 30, 2020, a decrease of $1.2 million, or 13%. These expenses decreased due to a $2.0 million decrease in employee headcount related costs, and a decrease in travel related expenses of $0.2 million, partially offset by an increase in marketing related expenses of $0.9 million.

General and Administrative.

General and administrative expenses for the three months ended September 30, 2021, were $3.0 million, as compared to $2.5 million for the three months ended September 30, 2020, an increase of $0.5 million, or 20%. This increase was due to an increase of $0.8 million in base debt related expenses, partially offset by a decrease of $0.3 million in payroll related expenses.

General and administrative expenses for the nine months ended September 30, 2021, and 2020, were a consistent $7.6 million as a result of decreases in payroll related expenses of $0.4 million and other office related expenses of $0.1 million, partially offset by an increase in payroll related expenses of $0.5 million.

22

Legal expenses.

Legal expenses for the three months ended September 30, 2021, were $1.0 million, as compared to $1.8 million for the three months ended September 30, 2020, a decrease of $0.8 million, or 45%. The decrease of $0.8 million was primarily due to decreased expenses related to the SEC investigation.

Legal expenses for the nine months ended September 30, 2021, were $4.3 million, as compared to $5.4 million for the nine months ended September 30, 2020, a decrease of $1.1 million, or 20%. Legal expenses were higher than expected for the nine months ended September 30, 2021, and 2020 due to shareholder litigation as well as the ongoing SEC investigation. Legal expenses for the nine months ended September 30, 2021, include $4.3 million related to the SEC investigation. Legal expenses in the nine months ended September 30, 2020, include a $2.0 million legal settlement associated with the shareholder litigation and $3.4 million in other legal expenses, primarily related to the SEC investigation.

Restructuring Costs

In September 2019, our Board of Directors approved, and our management commenced and completed, a restructuring plan to reduce operating costs and better align our workforce with the needs of our business. During the nine months ended September 30, 2021, we did not record any costs related to restructuring. During the nine months ended September 30, 2020, $1.1 million was recorded in restructuring costs. Our total worldwide employee count as of September 30, 2021, was 78.

Interest and Other Expense, net

We recorded $0.1 million in foreign exchange loss for the three months ended September 30, 2021. We recorded $0.2 million in net interest expense for the three months ended September 30, 2020. The decrease in interest expense is a result of the payoff of the outstanding indebtedness to B. Riley Principal Investments, LLC (“BRPI”) in June 2020.

We recorded $0.3 million in foreign exchange loss for the nine months ended September 30, 2021, compared to $0.4 million in foreign exchange loss and $0.8 million in net interest expense for the nine months ended September 30, 2020. The decrease in interest expense is a result of the payoff of the outstanding indebtedness to BRPI in June 2020.

Income Tax Expense

We recognized income tax expense of $0.2 million for the three months ended September 30, 2021 and 2020.

We recognized income tax expense of $0.2 million for the nine months ended September 30, 2021, as compared to income tax expense of $0.5 million for the nine months ended September 30, 2020.

Liquidity and Capital Resources

Historically, we have funded operations from a combination of public and private equity financings, convertible loans from existing investors and borrowings under loan agreements. As of September 30, 2021, we did not have any convertible loans or any other borrowing structures in place.  

Currently, our principal source of liquidity consists of cash and cash equivalents totaling $10.2 million, as September 30, 2021. During the nine months ended September 30, 2021, our net loss was $26.9 million, and it is likely that we will continue to experience operating losses into the future because we have not yet generated sufficient revenue levels needed to ensure profitability.  Our cash balance during the quarter ended September 30, 2021, increased by $3.0 million primarily due to our ATM program. Although we remain subject to the risks and uncertainties associated with the development and release of new products, among others, we believe our operations have been streamlined to enable us to conduct business more effectively and efficiently despite near term economic uncertainty. However, our liquidity has been negatively impacted by a decline in the sales of our legacy products while our next generation products are still under development. In addition, legal expenses related to our ongoing SEC investigation have been significantly higher than expected and may continue to impact our results in the foreseeable future. In addition, the terms and conditions of applicable bylaws, certificates or articles of incorporation, agreements or applicable law may obligate us under certain circumstances to indemnify our current and former directors, officers or employees, and underwriters, with respect to certain of our litigation matters, including the ongoing SEC investigation, and we have been advancing legal fees and costs to certain current and former directors, officers, employees and underwriters in connection with certain of the matters disclosed in Note 11, Commitments and Contingencies. As a result of the foregoing, substantial doubt exists regarding our ability to continue as a going concern for a period of at least one year from the date of issuance for the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

23

To alleviate these conditions, our management is currently evaluating various funding alternatives and may seek to raise additional funds through the issuance of equity, mezzanine or debt securities, through arrangements with strategic or investment partners with greater resources or access to funds or through obtaining credit from government or financial institutions. As we seek additional sources of financing, there can be no assurance that such financing would be available to us on favorable terms or at all. Our ability to obtain additional financing in the debt and equity capital markets, including through our ATM Program, is subject to several factors, including market and economic conditions, our performance and investor sentiment with respect to us and our industry. See risk factor entitled “Our liquidity has been adversely impacted by our ongoing net losses, including as a result of declines in the sales of our legacy products while our next generation products are still under development and our ongoing SEC investigation, and there is no assurance that we will have sufficient liquidity to continue operations.” in this Quarterly Report on Form 10-Q for additional information.

Our cash balance as of October 31, 2021, was approximately $17.5 million.

During the three months ended September 30, 2021, we issued and sold an aggregate of 2,555,788 shares of our common stock at an average price per share of $4.0641 under the June 2021 ATM Program and the ATM Program for net proceeds of approximately $10.3 million of which approximately $9 million was received during the quarter and $1.3 million was received October 2021. Subsequent to September 30, 2021, we issued and sold an aggregate of 6,813,183 shares of our common stock at an average price per share of $2.10 under the ATM Program for net proceeds of approximately $14.3 million.  As of October 31, 2021, we have approximately $24.8 million available for future issuances under the ATM Program.  See “Recent Developments – ATM Program” for additional information.

The accompanying condensed consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

Summary of Cash Flows

Cash and cash equivalents as of September 30, 2021, was $10.2 million, or $11.9 million lower than net cash of $22.1 million on December 31, 2020. The decrease was driven primarily by legal expenses and research and development.

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

	Nine Months ended September 30,
(in thousands)	2021			2020
Net cash used in operating activities	$	(20,912	)	$	(710	)
Net cash used in investing activities		(20	)	(203		)
Net cash provided by financing  activities		8,978			21,287
Net increase (decrease) in cash and cash equivalents		(11,954	)		20,374

Cash flows from operating activities

For the nine months ended September 30, 2021, cash used in operating activities was $20.9 million, primarily attributable to net loss of $26.9 million, partially offset by non-cash charges of $3.1 million and a net change in our net operating assets and liabilities of $2.9 million. Non-cash charges primarily consisted of $1.6 million in depreciation and amortization,$0.8 million in stock-based compensation expense and $0.7 million in allowance for bad debt. The change in our net operating assets and liabilities was primarily due to a net increase of $1.7 million in accounts and non-trade receivables, and a $0.5 million increase in prepaids and other assets, partially offset by a $3.7 million net increase in accounts payable, accrued expenses and warranty liability and a $1.4 million decrease in inventory.

For the nine months ended September 30, 2020, cash used in operating activities was $0.7 million, primarily attributable to net loss of $23.5 million, partially offset by a net change in our net operating assets and liabilities of $18.5 million, and non-cash charges of $4.3 million. Non-cash charges primarily consisted of $2.3 million in depreciation and amortization, $0.8 million in stock compensation expense, $0.4 in inventory write-downs, $0.3 million in bad debt expense $0.3 in non-cash interest expense and $0.2 million in accretion of debt discount. The change in our net operating assets and liabilities was primarily due to a $4.3 million decrease in accounts receivables, a $6.3 million decrease in inventory, and an increase of $7.6 million net increase in accounts payable and accrued expenses.

24

Cash flows from investing activities

For the nine months ended September 30, 2021, there was $0.02 million of cash used in investing activities.

For the nine months ended September 30, 2020, cash used in investing activities was $0.2 million attributable to purchases of property and equipment.

Cash flows from financing activities

For the nine months ended September 30, 2021, cash provided by financing activities was $9.0 million, primarily due to $9.0 in net proceeds from our current and prior ATM Program, offset by repayment of an outstanding debt obligation $0.1 million to a supplier.

For the nine months ended September 30, 2020, cash provided by financing activities was $21.3 million, primarily derived from the net proceeds of our public offering of $25.2 million, and from the exercise of stock options of $0.3 million, partially offset by $4.1 million related to the payoff of the outstanding indebtedness to BRPI.

Off-Balance Sheet Arrangements

As of September 30, 2021, we had no off-balance sheet arrangements and did not have any holdings in variable interest entities.

Critical Accounting Policies and Significant Judgments and Estimates

Critical Accounting Policies and Estimates 

Our discussion and analysis of financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in conformity with accounting principles generally accepted in the United States of America. Certain accounting policies and estimates are particularly important to the understanding of our financial position and results of operations and require the application of significant judgment by our management or can be materially affected by changes from period to period in economic factors or conditions that are outside of our control. As a result, they are subject to an inherent degree of uncertainty. In applying these policies, our management uses their judgment to determine the appropriate assumptions to be used in the determination of certain estimates. Those estimates are based on our historical operations, our future business plans and projected financial results, the terms of existing contracts, our observance of trends in the industry, information provided by our customers and information available from other outside sources, as appropriate. While the nature of the COVID 19 situation is dynamic, we have considered its impact when developing our estimates and assumptions. Actual results and outcomes may differ from management's estimates and assumptions. 

A description of our critical accounting policies that represent the more significant judgments and estimates used in the preparation of our consolidated financial statements was provided in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended December 31, 2020. There have been no changes to our critical accounting policies and estimates described in the Annual Report on Form 10-K for the year ended December 31, 2020, that have had a material impact on our condensed consolidated financial statements and related notes. 

Recently Issued Accounting Pronouncements

See Note 1 to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for recently issued accounting pronouncements.

Segment Information

We have one business activity and operate in one reportable segment.

25

JOBS Act

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. We expect to use the extended transition period for any other new or revised accounting standards during the period in which we remain an emerging growth company. As a result, our condensed consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year following the fifth anniversary of the consummation of our initial public offering, (ii) the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion, (iii) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year, or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. Even after we no longer qualify as an emerging growth company, we may still qualify as a smaller reporting company, which would allow us to take advantage of many of the same exemptions from disclosure requirements, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, and reduced disclosure obligations regarding executive compensation in our prospectuses and in our periodic reports and proxy statements.

26

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information under this item.

Item 4. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive and 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 this evaluation, and as a result of the material weakness in our internal control over financial reporting described below, as well as our failure to include management’s report on internal controls in our original Annual Report on Form 10-K for the year ended December 31, 2020, our principal executive and 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 not effective at the reasonable assurance level.

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in those internal controls. With respect to the year ended December 31, 2020, we identified a material weakness in our internal controls over financial reporting related to the design and implementation of our IT general controls including elevated (administrator) access to financial reporting systems and subsystems. Although we have made progress with the remediation of these issues, these efforts may not be sufficient to avoid similar material weaknesses in the future.

In response to the conclusion set forth above, management intends to implement the remedial measures described in Management’s Report on Internal Control Over Financial Reporting in Part II, Item 9A of our Annual Report on Form 10-K for the year ended December 31, 2020, as well as the following additional remedial measures:

• Evaluate and improve our disclosure committee process, procedures and meetings, including specific requirements to consider our internal control over financial reporting and the impact of the remedial measures described below; and

• Retained outside consultants in June 2021, to specifically evaluate our disclosure controls and procedures. Work is in process.  

(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 relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the impact of the COVID-19 pandemic on our internal controls to minimize the impact on their design and operating effectiveness.

(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 principal executive officer and our principal 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 not effective to provide reasonable assurance that the objectives of our disclosure control system were met.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

See Note 10 in this Quarterly Report on Form 10-Q for more information regarding legal proceedings.

Item 1A. Risk Factors.

With the exception of the following risk factors, there are no material changes to the risk factors set forth in Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2020:

We have failed, and may continue to fail, to meet the listing standards of Nasdaq, and as a result our common stock may become delisted, which could have a material adverse effect on the liquidity of our common stock.

Our common stock is currently listed for trading on the Nasdaq Capital Market. We must satisfy Nasdaq’s continued listing requirements, including, among others, a minimum stockholders’ equity of $2.5 million and a minimum bid price for our common stock of $1.00 per share, or risk possibly delisting, which would have a material adverse effect on our business. On April 29, 2021, we received a letter from the Listing Qualifications staff of Nasdaq indicating that, based upon the closing bid price of our common stock for the prior 30 consecutive business days, we no longer met the requirement of the Nasdaq Capital Market to maintain a minimum bid price of $1 per share, as set forth in Nasdaq Listing Rule 5550(a). As discussed under “Recent Developments” included elsewhere in this report, on September 15, 2021, we effected a 1-for-10 Reverse Stock Split in order to regain compliance with the minimum bid price requirement and, on September 30, 2021, Nasdaq informed us that we had regained full compliance with Nasdaq’s continued listing requirements. However, there can be no assurance that we will be able to maintain compliance with Nasdaq’s continued listing requirements. If we do not maintain compliance with the Nasdaq continuing listing requirements, our common stock may be delisted from the Nasdaq Capital Market and it could be more difficult to buy or sell our securities and to obtain accurate quotations, and the price of our common stock could suffer a material decline. In addition, a delisting would impair our ability to raise capital through the public markets, could deter broker-dealers from making a market in or otherwise seeking or generating interest in our securities and might deter certain institutions and persons from investing in our securities at all.

Our unaudited condensed consolidated financial statements included a statement that there is a substantial doubt about our ability to continue as a going concern and a continuation of negative financial trends could result in our inability to continue as a going concern.

Our unaudited condensed consolidated financial statements as of and for the nine months ended September 30, 2021, were prepared on the assumption that we would continue as a going concern. Our unaudited condensed consolidated financial statements as of and for the nine months ended September 30, 2021, did not include any adjustments that might result from the outcome of this uncertainty. As a result of our ongoing net losses, there is substantial doubt about our ability to continue as a going concern over the next twelve months. The reaction of investors to our potential inability to continue as a going concern, could materially adversely affect the price of our common stock.

Additionally, if our projected operating results fail to improve, our liquidity could be further adversely impacted, and we may need to seek additional sources of funding. We are actively pursuing expanding our business and increasing our revenue opportunities while effectively managing business operations and exploring further cost saving opportunities. We may not be successful in these efforts, in which case, we may need to seek to raise additional capital from the sale of equity securities or the incurrence of indebtedness to allow us to invest in growth opportunities. There can be no assurance that additional financing will be available to us on acceptable terms, or at all. Additionally, if we continue to issue additional equity securities to raise funds, whether to existing investors or others, or through our ATM Program or otherwise, the ownership percentage of our existing stockholders would be reduced. New investors may demand rights, preferences, or privileges senior to those of existing holders of common stock. We may also be limited as to the amount of funds we can raise pursuant to SEC rules and the continued listing requirements of Nasdaq.

28

Our liquidity has been adversely impacted by our ongoing net losses, including as a result of declines in the sales of our legacy products while our next generation products are still under development and our ongoing SEC investigation, and there is no assurance that we will have sufficient liquidity to continue operations.

We have incurred significant net losses since 2013 and have an accumulated deficit of $223.1 million as of September 30, 2021. In the nine months ended September 30, 2021, our liquidity has been further negatively impacted by a decline in the sales of our legacy products while our next generation products are still under development. In addition, legal expenses related to our ongoing SEC investigation during the nine months ended September 30, 2021, were significantly higher than expected and may continue to impact our results in the foreseeable future. In addition, the terms and conditions of applicable bylaws, certificates or articles of incorporation, agreements or applicable law may obligate us under certain circumstances to indemnify our current and former directors, officers or employees, and underwriters, with respect to certain of our litigation matters, including the ongoing SEC investigation, and we have been advancing legal fees and costs to certain current and former directors, officers, employees and underwriters in connection with certain of the matters disclosed in Note 11, Commitments and Contingencies. As a result of the foregoing, we will need to obtain additional financing to fund our operations. We cannot provide any assurance that we will be able to secure sufficient liquidity to fund our operations, including through additional capital from the sale of equity securities or financings, or that we will be able achieve profitability through the roll-out of our next-generation products or the cost efficiencies implemented in 2020. If we are unable to generate or obtain the requisite amount of financing needed to fund our business operations, our liquidity and ability to continue operations could be materially adversely affected. As a result, we may be required to delay, reduce or cease our operations and we may be required to seek bankruptcy protection.

We may not be able to continue to develop solutions to address user needs effectively, including our next generation products, which would materially adversely affect our liquidity and our ability to continue operations.

Our industry is characterized by:

• evolving industry standards;

• frequent new product and service introductions;

• evolving distribution channels;

• increasing demand for customized product and software solutions;

• rapid competitive developments; and

• changing customer demands.

Technological advancements could render our products obsolete, which typically erodes prices and causes products to become unmarketable. Our success will depend on our ability to respond to changing technologies and customer requirements, and our ability to develop and introduce new and enhanced products in a cost-effective and timely manner. For example, our products are compatible with fourth generation, or 4G, technology, but emerging fifth generation wireless, or 5G, technology is expected to require network infrastructure upgrades, which could require us to update and migrate all of our systems from 4G to 5G. In addition, several of our legacy products are nearing or have reached the end of their product lifecycle and are becoming obsolete due to technological advancements and ongoing change in the industry. As a result, we have experienced significant declines in revenue in recent quarters due to a drop in the number of unit sales of these legacy handheld devices. For example, during the nine months ended September 30, 2021, the number of unit sales of our legacy rugged handheld devices decreased by 79,699, or 39%, compared to the nine months ended September 30, 2020, primarily as a result of these products reaching the end of their product lifecycle.

As a result, we are currently prioritizing spending on research and development of our next generation ruggedized mobile phones, which we currently anticipate launching in the third quarter of 2021. However, the research and development necessary to launch our next generation products will require us to incur additional costs and our liquidity continues to be adversely impacted by our ongoing net losses. There can be no assurance that we will have sufficient resources to complete the development of our next generation ruggedized mobile phones and bring them to market. Even if we are able to introduce our next generation ruggedized mobile phones to the market,  there can be no assurance that these new product introductions will lead to any sales or increase in revenue. If we fail to develop these next generation products or enhancements on a timely and cost-effective basis, or if our new products or enhancements fail to achieve market acceptance, our business, operations, financial condition and liquidity would be further materially adversely affected and we may be required to delay, reduce or cease our operations and we may be required to seek bankruptcy protection. See above under “Our liquidity has been adversely impacted by our ongoing net losses, including as a result of declines in the sales of our legacy products while our next generation products are still under development and our ongoing SEC investigation, and there is no assurance that we will have sufficient liquidity to continue operations.”

Further, the development of new or enhanced products is a complex and uncertain process requiring the accurate anticipation of technological and market trends. We may experience design, manufacturing, marketing, and other difficulties that could delay or

29

prevent the development, introduction or marketing of our new products and enhancements. If we experience delays with new products, if our expectations regarding market demand and direction are incorrect, if sales of our existing products begin to decline more rapidly, or if the rate of decline continues to exceed the rate of growth of our next generation products, it will materially and adversely affect our business, results of operations and financial condition, and may require us to significantly reduce or even eliminate certain research and development programs.

We are dependent on the continued services and performance of a concentrated and limited 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 and limited group of senior management and other key personnel. As previously disclosed, beginning in 2021, we outsourced substantially all of our software development and manufacturing work to third parties and, as part of these outsourcings, we transferred or eliminated a significant number of employees. As of September 30, 2021, our worldwide employee headcount was 78 employees, down from 317 employees at December 31, 2020, and 500 employees at December 31, 2019. Our senior management team is also small, with Mr. Robert Tirva serving as our President, Chief Operating Officer and Chief Financial Officer as of May 31, 2021. We currently have no Chief Executive Officer.  

Due to the small size of our Company and our limited number of employees, each member of our executives, managers and other key personnel serve a critical role to our success. If we are unable to retain sufficiently experienced and capable employees, including those who can help us increase revenues generated from our end market segments, our business and financial results may suffer. The loss of the services of any additional executives, managers or other key personnel could impede the achievement of our strategic objectives, seriously harm our ability to successfully implement our business strategy and adversely impact our operating results. In addition, if additional executives, managers or other key personnel resign, retire or are terminated, or their service is otherwise interrupted, including due to COVID-19, we may not be able to replace them in a timely manner and we could experience significant declines in productivity and/or errors due to insufficient staffing or managerial oversight. Moreover, experienced and capable employees in the technology industry remain in high demand, and there is continual competition for their talents. Given our size, we may be at a disadvantage, relative to our larger competitors, in the competition for these personnel.

We cannot assure you that our exploration of strategic and financing alternatives will result in a transaction and/or financing or that any such transaction or financing would be successful, and the process of exploring strategic and financing alternatives or its conclusion could adversely impact our business and our stock price.

In August 2021, we announced that we had initiated a review of our strategic alternatives and capital market options, including both buy and sell side opportunities. This process is ongoing, and we engaged B. Riley to assist in the process.

There can be no assurances that the strategic and financing alternatives process will result in the announcement or consummation of any strategic or financing transaction, or that any resulting plans or transactions will yield additional value for shareholders. Any potential transaction would be dependent on a number of factors that may be beyond our control, including, among other things, market conditions, industry trends, the interest of third parties in any potential transaction with the Company.

The process of exploring strategic and financial alternatives could adversely impact our business, financial condition and results of operations. We could incur substantial expenses associated with identifying and evaluating potential strategic and financing alternatives, including those related to equity compensation, severance pay and legal, accounting and financial advisory fees. In addition, the process may be time consuming and disruptive to our business operations, could divert the attention of management and the board of directors from our business, could negatively impact our ability to attract, retain and motivate key employees, and could expose us to potential litigation in connection with this process or any resulting transaction. The public announcement of a strategic or financing alternative may also yield a negative impact on operating results if prospective or existing customers are reluctant to commit to new products or if existing customers decide to shift their business to a competitor. Further, speculation regarding any developments related to the review of strategic or financial alternatives and perceived uncertainties related to the future of the Company could cause our stock price to fluctuate significantly.

On the date of each annual meeting of stockholders, each non-employee director who will continue as a non-employee director following such meeting shall, automatically, and without further action by the Board or the Compensation Committee of the Board, be granted an annual award of RSUs having a grant date Fair Market Value (as defined in 2019 Plan) of $60,000 (the “Annual Grant”).

The Annual Grant RSUs will fully vest on the earlier of the first anniversary of the grant date or immediately prior to the next annual meeting of stockholders, subject to continuous service.

If a non-employee director is appointed or elected to the Board other than in connection with an annual meeting of stockholders, then (i) such non-employee director shall be awarded the full Initial Grant as provided above upon such non-employee director’s appointment or election, and (ii) the Annual Grant to be granted to such non-employee director at the first annual meeting of stockholders following such appointment or election shall be pro-rated for the number of months served prior to such annual meeting of stockholders.

The RSUs will be granted under and subject to the terms of the 2019 Plan. The number of shares of common stock subject to each RSU award granted under this Policy will be the quotient of the dollar value of the award divided by the closing price of the Company’s common stock on the date of grant, rounded down to the nearest whole share.  Each RSU award granted under this Policy will fully vest upon (a) a Change in Control (as defined in the 2019 Plan) and (b) the non-employee director’s death or Disability (as defined in the Plan).

Cash Retainers

Each non-employee director will be entitled to receive an annual cash retainer of $35,000 for service on the Board and additional annual cash compensation for Board committee membership as follows:

Position	Annual Cash Retainer
Audit Committee Chair	$15,000
Audit Committee Member	$7,500
Compensation Committee Chair	$10,000
Compensation Committee Member	$5,000
Nominating & Corporate Governance Committee Chair	$7,500
Nominating & Corporate Governance Committee Member	$3,750

The chair of each committee is eligible to receive a retainer for service as the chair, but not an additional retainer for service as a member of the committee.  

If one is appointed, the non-executive chairman of the Board will also be entitled to receive an additional annual cash retainer of $25,000.

Cash retainers shall be paid quarterly in arrears and shall be paid pro-rata for less than a full quarter of service.  

The Company will also reimburse all reasonable out-of-pocket expenses incurred by non-employee directors for their attendance at meetings of our Board or any committee thereof. To the extent that any taxable reimbursements are provided to a non-employee director, they will be provided in accordance with Section 409A of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations and other guidance thereunder and any state law of similar effect, including, but not limited to, the following provisions: (i) the amount of any such expenses eligible for reimbursement during the non-employee director’s taxable year may not affect the expenses eligible for reimbursement in any other taxable year; (ii) the reimbursement of an eligible expense must be made no later than the last day of the non-employee director’s taxable year that immediately follows the taxable year in which the expense was incurred; and (iii) the right to any reimbursement may not be subject to liquidation or exchange for another benefit.

Note:  Non-employee director compensation set forth in this Policy is subject to the 2019 Plan, which currently limits non-employee director compensation (cash and equity combined) to $600,000 per calendar year or $1,000,000 with respect to the non-employee director’s initial year of service.

The Company and its significant accounting policies

SONIM TECHNOLOGIES, INC

NOTES TO CONDENSED 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

Basis of presentation and preparation

The condensed consolidated financial statements include the accounts of Sonim Technologies, Inc. and its wholly owned subsidiaries (collectively “Sonim” or the “Company”). Intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The preparation of these condensed consolidated financial statements and accompanying notes in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from those estimates. Certain prior period amounts in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and accompanying notes included in its Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”).

On September 15, 2021, the Company effected a 1-for-10 stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock on that date. Additionally, the number of shares of the Company’s common stock subject to outstanding stock options and restricted stock units, the exercise price of all of its outstanding stock options, and the number of shares of common stock reserved for future issuance pursuant to its equity compensation plans were adjusted proportionately in connection with the Reverse Stock Split. The number of authorized shares of common stock under the Company’s Amended and Restated Certificate of Incorporation and the par value per share of its common stock were unchanged. All historical share and per share amounts presented herein have been adjusted retrospectively to reflect these changes.

Liquidity and Going Concern

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with GAAP.

Pursuant to the requirements of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

The Company had cash and cash equivalents of $10,187 and an accumulated deficit of $223,083 at September 30, 2021, and a net loss of $10,939 for the quarter ended September 30, 2021. Since inception, the Company has been developing ultra-rugged mobile phones and accessories designed specifically for task workers physically engaged in their work environments, often in mission-critical roles. The Company’s ability to continue as a going concern is dependent on its ability to complete ongoing and future development of its ultra-rugged mobile phones and accessories, continue commercial scale production and sell its products. The Company believes that its current level of cash and cash equivalents are not sufficient to fund commercial scale production and product sales. These conditions raise substantial doubt regarding the Company’s ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements.

To alleviate these conditions, management is currently evaluating various funding alternatives and may seek to raise additional funds through the issuance of equity, mezzanine or debt securities, through arrangements with strategic or investment partners with greater resources or access to funds or through obtaining credit from government or financial institutions. As the Company seeks additional sources of financing, there can be no assurance that such financing would be available to the Company on favorable terms or at all. The Company’s ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to the Company and its industry.

New accounting pronouncements:

Pronouncements adopted in 2021:

In December 2019, FASB issued Accounting Standards Update (ASU) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes by removing certain exceptions to the general principles of ASC 740 in order to reduce cost and complexity of its application.  The ASU removes the exception related to the incremental approach for intra-period tax allocation, as well as two exceptions related to account for outside basis differences of equity method investments and foreign subsidiaries. This guidance is effective for fiscal years beginning after December 31, 2021, with early adoption permitted. The Company adopted ASU 2019-12 on January 1, 2021. The adoption of ASU 2019-12 did not have an impact on the Company’s condensed consolidated financial statements.

Pronouncements not yet adopted:

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 to control the use of the given asset assumed under the lease. As an emerging growth company, the Company has elected to adopt the standard based on nonpublic business entities implementation dates for annual reporting periods beginning after December 15, 2021. The Company is currently evaluating this new standard and the impact it will have on its condensed consolidated financial statements, information technology systems, process, and internal controls.

Revenue From Contract With Customer [Abstract]

Revenue Recognition

NOTE 2 —Revenue recognition

The Company recognizes revenue primarily from the sale of products, including its mobile phones, barcode scanners and accessories, and the majority of the Company’s contracts include only one performance obligation, namely the delivery of product. A performance obligation is a promise 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, Revenue from Contracts with Customers. The Company also recognizes revenue from other contracts that may include a combination of products and non-recurring engineering (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 promises as individual performance obligations if they are concluded as distinct. Performance obligations are considered distinct if they are both capable of being distinct and distinct within the context of the contract. In determining whether performance obligations meet the criteria for being distinct, the Company considers a number of factors, such as the degree of interrelation and interdependence between obligations, and whether or not the good or service significantly modifies or transforms another good or service in the contract. During the three and nine months ended September 30, 2021, and 2020, the Company did not have any contracts in which the products and NRE services were concluded to be a single performance obligation. In certain cases, the Company may offer tiered pricing based on volumes purchased for specific products. To date, all tiered pricing provisions have fallen into observable ranges of pricing to existing customers, thus, not resulting in any material right which could be concluded as its own performance obligation. In addition, the Company does not offer material post-contract support services to its customers.

Net revenue for an individual contract is recognized at the related transaction price, which is the amount the Company expects to be entitled to in exchange for transferring the goods and/or services. The transaction price for product sales is calculated as the product selling price, net of variable consideration, which may include estimates for marketing development funds, sales incentives, and price protection and stock rotation rights. The Company records reductions to net revenues related to future product returns based on the Company’s expectations and historical experience. Typically, variable consideration does not need to be constrained as estimates are based on specific contract terms. However, the Company continues to assess variable consideration estimates such that it is probable that a significant reversal of revenue will not occur. The transaction price for a contract with multiple performance obligations is allocated to the separate performance obligations on a relative standalone selling price basis. Standalone selling prices for products are determined based on the prices charged to customers, which are directly observable. Standalone selling price of the professional services are mostly based on time and materials. The Company determines its estimates of variable consideration based on historical collection experience with similar payor classes, aged accounts receivable by payor class, terms of payment agreements, correspondence from payors related to revenue audits or reviews, the Company’s historical settlement activity of audited and reviewed claims and current economic conditions using the portfolio approach. Revenue is recognized only to the extent that it is probable that a significant reversal of the cumulative amount recognized will not occur in future periods.

Revenue is then recognized for each distinct performance obligation as control is transferred to the customer. Revenue attributable to hardware is recognized at the time control of the product transfers to the customer. Control is generally transferred when the Company has a present right to payment and title and the significant risks and rewards of ownership of products or services are transferred to its

customers. For most of the Company’s revenue attributable to hardware, control transfers when products are shipped. Revenue attributable to professional services is recognized as the Company performs the professional services to the customer.

Disaggregation of revenue

The following table presents the Company’s net revenue disaggregated by product category:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2021		2020		2021		2020

Shipping and handling costs

The Company has elected to account for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products.

Distributor returns allowance

The Company records reductions to net revenues related to future distributor product returns based on the Company’s expectation. The Company had allowances for distributor product returns totaling approximately $300 as of September 30, 2021.

Contract costs

Applying the practical expedient, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred when the amortization period of the assets that otherwise would have been recognized is one year or less. These costs are included in sales and marketing  expenses.

The non-recurring costs associated with design and development of new products for technical approval, represent costs to fulfill a contract pursuant to ASC 340-40 Other Assets and Deferred Costs. Accordingly, the Company capitalizes these non-recurring engineering costs and amortizes such costs over the estimated period of time over which they are expected to be recovered, which is typically 4 years, the estimated life of a particular model phone.

The total capitalized costs to fulfill a contract is primarily associated with Company’s introduction of the XP8 model phone and now the XP3 Plus model feature phone. As of September 30, 2021, and December 31, 2020, the total costs to fulfill a contract included in other assets were $2,684 and $2,889, respectively.

Contract balances

The Company records accounts receivable when it has an unconditional right to consideration. As of September 30, 2021, the Company did not have a contract receivable balance. Contract liabilities are recorded when cash payments are received or due in advance of performance. Contract liabilities consist of advance payments and deferred revenue, where the Company has unsatisfied performance obligations. Contract liabilities are presented as a component of deferred revenue on the condensed consolidated balance sheets. As of January 1, 2021, and September 30, 2021, the contract liabilities were $5 and zero, respectively.

The following table is a rollforward of contract balances as of September 30, 2021:

	Contractual
	Liability
Balance at, January 1, 2021	$	5
Recognition of revenue		(880	)
Addition to deferred revenue		875
Balance at, September 30, 2021	$	—

Concentration of Customers

Revenue from customers with concentration greater than 10% in the three and nine months ended September 30, 2021, and 2020 accounted for approximately the following percentage of total revenues:

	Three Months Ended September 30,		Nine Months Ended September 30,

Fair Value Measurement

Fair Value Disclosures [Abstract]

Fair Value Measurement

NOTE 3 —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:

• Quoted market prices for similar assets or liabilities in active markets;

• Quoted prices for identical or similar assets or liabilities in inactive markets;

• Inputs other than quoted prices that are observable for the asset or liability;

• Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

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 assets 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 September 30, 2021, and December 31, 2020.

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

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 at fair value:

NOTE 8 —Stockholders’ Equity

On September 15, 2021, the Company effected a 1-for-10 stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock on that date. Additionally, the number of shares of the Company’s common stock subject to outstanding stock options and restricted stock units, the exercise price of all of its outstanding stock options, and the number of shares of common stock reserved for future issuance pursuant to its equity compensation plans were adjusted proportionately in connection with the Reverse Stock Split. The number of authorized shares of common stock under the Company’s Amended and Restated Certificate of Incorporation and the par value per share of its common stock were unchanged. All historical share and per share amounts presented herein have been adjusted retrospectively to reflect these changes.

On June 30, 2021, we entered into an At Market Issuance Sales Agreement (“Sales Agreement”) with B. Riley Securities, Inc. and EF Hutton, a division of Benchmark Investments, LLC (“Sales Agents”) to sell shares of our common stock, $0.001 par value per share, having an aggregate offering price of up to $10,000, from time to time, through an “at-the-market offering” program (the “June 2021 ATM Program”). Under the terms of the Sales Agreement, we paid the Sales Agents a commission equal to 3.0% of the gross proceeds from each sale of common stock sold through it under the Sales Agreement. We exhausted this June 2021 ATM Program on July 14, 2021, selling an aggregate of 1,820,785 shares of our common stock at an average price per share of $4.59 and for net proceeds of approximately $8,363 during the three and nine months ended September 30, 2021.

On September 23, 2021, we entered into a new At Market Issuance Sales Agreement with the same B. Riley Securities, Inc., as sales agent, to sell shares of our common stock, $0.001 par value per share, having an aggregate offering price of up to $41,637 from time to time, through a new “at the market offering” program (the “ATM Program”). Under the terms of the Sales Agreement, we will pay B. Riley Securities, Inc. a commission equal to 3.0% of the gross proceeds from each sale of common stock sold through it under the Sales Agreement. From September 27, through September 30, 2021, we issued and sold an aggregate of 735,003 shares of our common stock at an average price per share of $2.69 under the ATM Program for net proceeds of approximately $1,974. All proceeds were received by September 30, 2021, with exception of $1,291, which were received by October 4, 2021. The outstanding net proceeds were classified as long term other assets since the cash was collected prior to the issuance of our financial statements, and as such, the statement of cashflows reflects $9,046 in cash collected as of September 30, 2021.

As of October 31, 2021, we had approximately $24.8 million available for future issuances under the ATM Program.

NOTE 11 —Commitments and Contingencies

The terms and conditions of applicable bylaws, certificates or articles of incorporation, agreements or applicable law may obligate Sonim under certain circumstances to indemnify its current and former directors, officers or employees, and underwriters, with respect to certain of the matters described below and Sonim has been advancing legal fees and costs to certain current and former directors, officers, employees and underwriters in connection with certain matters describe below.

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 2026. Royalty expense for the three months ended September 30, 2021, and 2020 was $524 and $470, respectively. Royalty expense for the nine months ended September 30, 2021, and 2020 was $1,369 and $1,664, respectively. The Company may be required to pay additional royalties to additional patent holder and technology providers on future products.

Securities litigation—On September 20, 2019, a purported Sonim stockholder who allegedly purchased stock registered in Sonim’s initial public offering (“IPO”) filed a putative class action complaint in the Superior Court of the State of California, County of San Mateo, captioned Pearson v. Sonim Technologies, Inc., et al., Case No. 19CIV05564, on behalf of himself and others who purchased shares of Sonim registered in the IPO (the “Pearson Action”). On October 4 and 16, 2019, two additional purported class action complaints substantially similar to the Pearson Action were filed on behalf of different plaintiffs yet the same putative class of Sonim stockholders, in the same court as the Pearson Action (the “’33 Act State Court Actions”). The defendants asked the Superior court to dismiss the “33 Act State Court Actions based on the provision in the Company’s Amended and Restated Certificate of Incorporation requiring stockholders to file and litigate in federal court any claims under the Securities Act of 1933. On December 7, 2020, the Superior Court entered an order granting defendants’ motion to dismiss. On October 7, 2019, a substantially similar putative class action lawsuit was filed in the United States District Court for the Northern District of California (the “’33 Act Federal Action”). All four complaints allege violations of the Securities Act of 1933 by Sonim and certain of its current and former officers and directors for, among other things, alleged false or misleading statements and omissions in the registration statement issued in connection with the IPO, relating primarily to an alleged failure to disclose software defects in Sonim’s phones and alleged misstatements about performance characteristics of Sonim’s phones. In July 2020, the Company entered into an agreement with the Lead Plaintiff in the ‘33 Act Federal Action to settle that case on a class wide basis for $2.0 million. As a result, the Company has paid out the $2.0 million settlement as of December 31, 2020. On March 5, 2021, the court presiding over the ’33 Act Federal Action granted final approval of the settlement.

Securities and Exchange Commission Formal Order of Private Investigation: In March 2020, the Company received a voluntary document request from the SEC San Francisco Regional office, and in August 2020, the Company was informed that the SEC Staff was conducting a formal investigation into events that occurred in 2018-2019.  The Company has been cooperating in the SEC’s ongoing investigation.  In October 2021, the Company and the SEC Staff began discussions regarding a potential resolution of the investigation, Those discussions are ongoing. The Company is unable to predict the likely outcome of the investigation, including whether it can be resolved through settlement negotiations, or determine its potential impact, if any, on the Company.

Derivative litigation— On September 21, 2020, the Company, and certain of its current and former directors and officers were sued

by a stockholder on behalf of our Company in a derivative action in the United States District Court for the District of Delaware, captioned Kusiak v. Plaschke, et al., Case No 20-cv-1270-MN (“Kusiak”). The Kusiak complaint is based largely on the same underlying factual allegations as the ’33 Act Federal Action.  The defendants filed a motion to dismiss the Kusiak derivative action based on plaintiff’s failure to make a litigation demand on Sonim’s directors.   On February 1, 2021, plaintiff in Kusiak voluntarily dismissed the action without prejudice.

On February 1, 2021, the same plaintiffs’ lawyers in the Kusiak action filed a new derivative action in the United States District Court for the District of Delaware against the Company and certain of its current and former directors and officers, captioned Gupta v. Plaschke, et al., Case No. 1:21-cv-130-MN (“Gupta”). The allegations in the Gupta complaint are generally similar to those in the Kusiak action. The defendants filed a motion to dismiss the Gupta derivative action based on plaintiff’s failure to make a litigation demand on Sonim’s directors. Given the early stages of this proceeding and the limited information available, the Company cannot predict the outcome of this legal proceeding or determine its potential impact, if any, on the Company.

General litigation—The Company is involved in various other legal proceedings arising in the normal course of business. The Company does not believe that the ultimate resolution of these other matters will have a material adverse effect on its condensed consolidated financial position, results of operations, or cash flows.

The results of any future litigation cannot be predicted with certainty and, regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management time and resources and other factors.

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 (Executive Severance Arrangements) 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 in accordance to the terms of the agreements. On May 31, 2021, the Company and Tom Wilkinson agreed that he will cease serving as the Company’s Chief Executive Officer.  In connection with his departure, the Company entered into a Separation and Release Agreement with him pursuant to which he will continue to be paid his base salary of $400, the rate in effect on the effective date for a period of twelve months, subject to tax withholding and any other authorized deductions, and will continue to be eligible for the Transaction Bonus Plan until November 30, 2021.

On December 11, 2019, the Board of Directors approved the Sonim Technologies Inc. Transaction Bonus Plan (the “Plan”) that is intended to incentivize Company employees who are in a position to significantly impact the value received by the Company’s stockholders in a change of control transaction. Pursuant to the Plan, upon consummation of a change of control transaction, 10% of the consideration payable to Company stockholders, after deducting transaction expenses, will be distributed to Plan participants, including the Company’s named executive officers. The Plan has a three-year term and may be extended by the administrator of the Plan. Subject to the terms of the Plan, participants must be continuously providing services to the Company through the date of the closing of a change in control transaction to be eligible to receive a bonus thereunder, except in the event of death or disability or involuntary termination without cause as further described in Section 5(c) and 5(d) of the Plan, and payment is contingent upon delivery and non-revocation of a general release of claims. In connection with the adoption of the Plan, the Board of Directors allocated a 50% interest in the Plan to Tom Wilkinson, the Company’s former Chief Executive Officer, and a 10% interest in the Plan to Robert Tirva, the Company’s President, Chief Operating Officer and Chief Financial Officer, and 35% to 6 other key employees and consultants.

At the beginning of 2021, the Company outsourced substantially all of its software development to a third-party and transferred 105 employees to support the ongoing work to be performed. In connection with outsourcing its software development, the Company entered into an agreement of future business volume over the next three years in the amount of $7.1 million, of which the Company has committed to that a minimum value of $3.1 million will be assured in the first year of business. The Company has paid $2.5 million during the nine months ended September 30, 2021.

Additionally, in the beginning of 2021, the Company outsourced its manufacturing work to a supply chain partner and transferred 22 employees as part of this solution.

During 2020, the Company continued to reduce headcount to better align its expenses with its revenue profile. The Company executed a reduction in force of approximately 10% of its U.S. employees in February 2020 and has also reduced headcount in certain international locations in India and Shenzhen. The Company has also relocated its headquarters from San Mateo, California to Austin, Texas, a lower cost location.

The Company and its Significant Accounting Policies (Policies)

Company And Significant Accounting Policies [Abstract]

Basis of Presentation and Preparation

Basis of presentation and preparation

The condensed consolidated financial statements include the accounts of Sonim Technologies, Inc. and its wholly owned subsidiaries (collectively “Sonim” or the “Company”). Intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The preparation of these condensed consolidated financial statements and accompanying notes in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from those estimates. Certain prior period amounts in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and accompanying notes included in its Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”).

On September 15, 2021, the Company effected a 1-for-10 stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock on that date. Additionally, the number of shares of the Company’s common stock subject to outstanding stock options and restricted stock units, the exercise price of all of its outstanding stock options, and the number of shares of common stock reserved for future issuance pursuant to its equity compensation plans were adjusted proportionately in connection with the Reverse Stock Split. The number of authorized shares of common stock under the Company’s Amended and Restated Certificate of Incorporation and the par value per share of its common stock were unchanged. All historical share and per share amounts presented herein have been adjusted retrospectively to reflect these changes.

Liquidity and Going Concern

Liquidity and Going Concern

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with GAAP.

Pursuant to the requirements of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

The Company had cash and cash equivalents of $10,187 and an accumulated deficit of $223,083 at September 30, 2021, and a net loss of $10,939 for the quarter ended September 30, 2021. Since inception, the Company has been developing ultra-rugged mobile phones and accessories designed specifically for task workers physically engaged in their work environments, often in mission-critical roles. The Company’s ability to continue as a going concern is dependent on its ability to complete ongoing and future development of its ultra-rugged mobile phones and accessories, continue commercial scale production and sell its products. The Company believes that its current level of cash and cash equivalents are not sufficient to fund commercial scale production and product sales. These conditions raise substantial doubt regarding the Company’s ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements.

To alleviate these conditions, management is currently evaluating various funding alternatives and may seek to raise additional funds through the issuance of equity, mezzanine or debt securities, through arrangements with strategic or investment partners with greater resources or access to funds or through obtaining credit from government or financial institutions. As the Company seeks additional sources of financing, there can be no assurance that such financing would be available to the Company on favorable terms or at all. The Company’s ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to the Company and its industry.

New accounting pronouncements

New accounting pronouncements:

Pronouncements adopted in 2021:

In December 2019, FASB issued Accounting Standards Update (ASU) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes by removing certain exceptions to the general principles of ASC 740 in order to reduce cost and complexity of its application.  The ASU removes the exception related to the incremental approach for intra-period tax allocation, as well as two exceptions related to account for outside basis differences of equity method investments and foreign subsidiaries. This guidance is effective for fiscal years beginning after December 31, 2021, with early adoption permitted. The Company adopted ASU 2019-12 on January 1, 2021. The adoption of ASU 2019-12 did not have an impact on the Company’s condensed consolidated financial statements.

Pronouncements not yet adopted:

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 to control the use of the given asset assumed under the lease. As an emerging growth company, the Company has elected to adopt the standard based on nonpublic business entities implementation dates for annual reporting periods beginning after December 15, 2021. The Company is currently evaluating this new standard and the impact it will have on its condensed consolidated financial statements, information technology systems, process, and internal controls.
