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 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.

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

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

	$	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.

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:
