SONIM TECHNOLOGIES INC

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(In Thousands, except Share and Per Share Amounts)

NOTE 1 —The Company and Its Significant Accounting Policies

Description of Business

Sonim Technologies, Inc. was incorporated in the state of Delaware on August 5, 1999, and is headquartered in San Diego, California. The Company offers a robust portfolio that includes rugged handsets, smartphones, wireless internet devices, software, services, and accessories. These products are engineered to deliver reliable communication in challenging and unpredictable environments, serving sectors such as critical communications, first responders, government, industrial, construction, hospitality, and logistics. The Company distributes its products primarily through major wireless carriers. The Company currently has products available at all three U.S. Tier-one carriers – AT&T, T-Mobile and Verizon as well as the three primary carriers in Canada – Bell, Telus and Rogers, Telstra in Australia, and multiple carriers throughout Europe. These carriers resell the Company’s products, along with network services, to end customers focusing on two primary end markets: industrial enterprise and the public sector.

The Company is executing a strategic expansion initiative, focusing on broadening its market reach with new products, geographical footprint, and customer segments including enterprise, small and medium business, and prosumers. This strategy is underpinned by a strong emphasis on execution. The Company has introduced new product categories: Connected Solutions featuring wireless internet products, a next-generation rugged smartphone, and a new range of mid and low-tier professional rugged phones, all boasting IP ratings, MIL-STD-810H standards, and elements of Sonim’s Rugged Performance Standards (“RPS”), highlighting the Company’s value proposition to target markets.

During the second half of 2024 and through the filing date of this report, the Company launched the following products:

Additionally, the XP10 is available through the Company’s distribution partners in EMEA and Australia. Most of these products are supported by the SonimWare™ platform and enterprise services. In the first half of 2025, all of the Company’s new products that launched with tier-one carriers in the United States included a certification associated with carrier first responder initiatives, including FirstNet Ready, FirstNet Trusted, Verizon Frontline Certified, and T-Mobile certified for T-Priority. In the first half of 2025 the Company also announced the upcoming launch and availability of the XP Pro Thermal 5G smartphone for Europe which includes an SDK-enabled Sonim IRIS software for custom application development and an integrated thermal camera by FLIR® that benefits a number of vertical trades such as electricians, plumbers, public safety, construction, agriculture, amongst others.

A significant revenue driver in the first quarter of 2024 was a range of low-priced products developed under Sonim’s original design manufacturer (“ODM”) model, emphasizing high-volume and low-margin production tailored to a specific customer’s needs. These sales concluded in the first quarter of 2024 due to its life cycle end. The ODM model does not represent the Company’s core business strategy.

Proposed Transaction with Social Mobile and Announced Strategic Initiatives

As further described in Note 11, Subsequent Events, below, on July 17, 2025, the Company entered into an asset purchase agreement (the “Asset Purchase Agreement”) by and among the Company, as seller, Pace Car Acquisition LLC, as buyer, (the “Buyer”), the Seller Representative named in the Asset Purchase Agreement, and, Social Mobile Technology Holdings LLC (the “Parent”), solely for the purpose of guaranteeing complete payment and performance obligations of the Buyer contained in the Asset Purchase Agreement.

The Asset Purchase Agreement pertains to the sale of substantially all of the Company’s assets. The Company also announced a strategic initiative to pursue a potential reverse takeover transaction in addition to the consummation of the asset sale, with the objective of maximizing stockholder value. This transaction would allow the public vehicle to continue as a reporting entity under a new name and trading symbol, and with a new business focus.

Reverse Stock Split

On July 17, 2024, the Company effected a 1-for-10 reverse stock split of its issued and outstanding common stock (the “Reverse Stock Split”). The Company’s common stock began trading on the Nasdaq Capital Market on a post-split basis on July 18, 2024. As a result of the Reverse Stock Split, each share of common stock issued and outstanding immediately prior to July 17, 2024, was automatically converted into one-tenth (1/10) of a share of common stock. The Reverse Stock Split affected all common stockholders uniformly and did not alter any stockholder’s percentage interest in the Company’s equity, except to the extent that the Reverse Stock Split would result in a stockholder owning a fractional share. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who otherwise would be entitled to receive a fractional share instead were entitled to receive one whole share in lieu of such fractional share.

The Reverse Stock Split did not change the par value of the common stock or the authorized number of shares of common stock. All outstanding stock options, restricted stock units, and warrants entitling their holders to purchase or obtain or convert into shares of our common stock were adjusted, as required by the terms of these securities.

The Company’s stockholders’ equity, in the aggregate, remained unchanged following the Reverse Stock Split. Net income (loss) per share increased because there were fewer shares of common stock outstanding. There were no other accounting consequences, including changes to the amount of stock-based compensation expense to be recognized in any period, that arose as a result of the Reverse Stock Split.

All common share and per-share amounts in this Form 10-Q have been retroactively restated to reflect the effect of the Reverse Stock Split.

Liquidity and Ability to Continue as a Going Concern

The Company’s condensed consolidated financial statements account for the continuation of its business as a going concern. The Company is subject to the risks and uncertainties associated with the development and release of new products. The Company’s principal sources of liquidity as of June 30, 2025, consist of existing cash and cash equivalents of $2,006. Subsequent to June 30, 2025, the Company received net proceeds of approximately $4,800 from the sale of shares through its public offering and net proceeds of approximately $2,320 from the sale of a promissory note, as well as entered into an additional receivables financing agreement for international receivables, which gives the Company access to up to €3,000 (see Note 11, Subsequent Events, for additional details). The Company believes that it can meet its obligations over the next twelve months following the filing date of this report with cash at June 30, 2025 and with the cash that was raised subsequent to June 30, 2025.

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, 2024.

As discussed above, all per share amounts and common shares amounts have been adjusted on a retroactive basis to reflect the effect of the Reverse Stock Split. Proportionate adjustments were made to the per share exercise price and number of shares of common stock issuable under all outstanding stock options, restricted stock units, and warrants. In addition, proportionate adjustments have been made to the number of shares of common stock reserved for the Company’s equity incentive awards.

Promissory Notes

The Company accounts for promissory notes in accordance with ASC 470,Debt. Promissory notes are initially recorded at the amount of cash proceeds received, net of any original issue discount and direct issuance costs. Debt discounts and issuance costs are amortized to interest expense over the term of the note using the straight-line method, which approximates the effective interest method. Interest is accrued based on the stated interest rate.

Prior period reclassifications

Certain amounts in prior periods have been reclassified to conform with current period presentation. These reclassifications had no effect on the reported results of operations.

Related Party Transactions

Effective December 15, 2023, in the ordinary course of business, the Company entered into an agreement pursuant to which the Company would execute various statements of work and sell white label phones under the ODM model arrangement with a then-related party, in which a family member of the Company’s then-director, Jeffrey Wang, holds indirect interest of approximately 40% (the “ODM Arrangement”). Pursuant to the ODM Arrangement, the Company consummated various transactions during the first quarter of 2024.

On April 1, 2025, the Company signed an agreement with a then-related party, in which a family member of the Company’s then-director, Jeffrey Wang, holds an indirect interest of approximately 40%, to purchase parts and components to be used in the manufacturing of the company’s products for the aggregate amount of approximately $1,000. The agreement was executed in the ordinary course of business. During the three months ended June 30, 2025, the Company purchased approximately $496 in raw materials under this agreement.

Subsequent to June 30, 2025, shareholders did not re-elect Jeffrey Wang as a director at the Company’s Annual Meeting.

NOTE 2 —Revenue Recognition

The Company recognizes revenue primarily from the sale of products, including mobile phones, connected devices, 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. The Company also recognizes revenue from other contracts that may include a combination of products and NRE services or from the provision of solely NRE services. Where there is a combination of products and NRE services, the Company accounts for the 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 six months ended June 30, 2025, and 2024, 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 model phones. 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 generally does not offer a right of return to its customers, except for certain distributors where the company estimates future returns and reduces revenue on sales subject to return and maintains a reserve for returns allowance. 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. The 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, its 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 for the customer.

The Company maintains agreements with certain customers that include provisions for product allowances under specific conditions. Accruals for these agreements are based on available customer-specific data or, when such data is not available, relevant historical trends. These costs are recognized as a reduction to revenue. Based on the terms of these agreements, any unused accruals are released and recognized as revenue. For the three and six months ended June 30, 2025, the Company finalized agreements which resulted in the reduction of accruals by approximately $219 and $5,490, respectively, which was recognized as revenue.

Disaggregation of revenue

The following table presents total net revenues disaggregated by product category:

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.

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 contract fulfillment costs and amortizes such costs over the estimated period of time they are expected to be recovered, which is typically three to four years, the estimated life of a particular product model. As of June 30, 2025, and December 31, 2024, the net contract fulfillment assets were $8,014 and $6,399, respectively.

If the Company determines that such contract fulfillment costs are not expected to be recovered, it records an impairment in the period such determination is made. During the three months ended June 30, 2024, the Company recorded an impairment of contract fulfillment assets of $3,217 due to a decrease in projected profit of one of its hotspots and the cancellation of a consumer durable product. During the three months ended June 30, 2025, the Company recorded an impairment of contract fulfillment assets of $1,084 due to the end of life of a legacy smartphone, which is included in cost of revenues in the Condensed Consolidated Statements of Operations.

NOTE 3 —Significant Balance Sheet Components

The following table presents the components of the Company’s accounts receivable, net:

As of January 1, 2024, accounts receivable, net, was $25,304 and non-trade receivables was $961.

The Company has non-trade receivables from manufacturing vendors resulting from the sale of components to the vendors who manufacture and assemble final products for the Company.

The Company determines the probability of default for each pool of receivables with similar risk characteristics. The probability of loss is applied to the value of the receivables and an allowance for potential credit losses is recorded with the offset to credit loss expense.

Three customers account for 27%,16%, and 11% of accounts receivable, net, at June 30, 2025. Three customers account for 33%,24%, and 12% of accounts receivable, net, at December 31, 2024.

In October 2023, the Company stopped sales of the white label products to its customer as the product reached the end of its life cycle. In February 2024, an agreement was executed that transferred $11,308 of the receivables to the manufacturer of the white label products in exchange for relieving the Company of a $11,308 accounts payable liability.

The following table presents the components of the Company’s inventory:

For certain new products, the Company began purchasing raw materials in 2024 that will be used by the third-party manufacturers to build the products. These purchased parts represent most of the raw materials in inventory at June 30, 2025 and December 31, 2024.

The following table presents the components of the Company’s prepaid expenses and other current assets:

The following table presents the components of the Company’s accrued liabilities:

Receivables Financing Agreement

On September 23, 2024, the Company entered into an invoice purchase agreement (the “Receivables Financing Agreement”) with LS DE LLC (“LS”), pursuant to which LS will provide receivables factoring to the Company. Pursuant to the terms of the Receivables Financing Agreement, LS will advance 80% of the face value of the receivables being sold by the Company, up to a maximum of $2,500 of eligible customer invoices from the Company. In consideration of the advances, LS is entitled to receive(i) an invoice purchase fee equal to 0.20% of the face amount of each purchased invoice payable at the time of the purchase and (ii) a daily funds usage fee equal to 0.0388%, payable monthly in arrears on the last day of each month. Under the agreement, the Company must repurchase any invoices that LS deems to be uncollectible or no longer qualify as an Eligible Account, as defined in the Receivables Financing Agreement. The Company is accounting for this transaction as a secured borrowing and recognizes a factoring liability for any advances until the accounts receivables are collected. As of December 31, 2024, there was $591 outstanding under the Receivables Financing Agreement, which is included in accrued liabilities in the Condensed Consolidated Balance Sheets. As of June 30, 2025, there were no borrowings outstanding under the Receivables Financing Agreement.

The Receivables Financing Agreement has an initial term of twelve months, subject to automatic annual extension unless terminated. Additionally, under certain circumstances and unless waived by LS, the Company will be obligated to pay a missing notation fee of 15% in the event of its failure to affix a certain legend regarding assignment or a misdirected payment fee in the amount of 15%. In the event of the Company’s default, the Company’s payment obligations will be accelerated, and, in addition to the aforementioned fees payable to LS, the Company will be required to pay the default interest rate of the lesser of 24% per annum or the maximum rate permitted by law until the default is cured or until all Company’s obligations are paid in full.

The Company’s obligations under the Receivables Financing Agreement are secured by a lien on all of the Company’s accounts receivable, inventory, and related property, excluding accounts receivable from certain specified counterparties.

The Receivables Financing Agreement contains representations and warranties by the Company and LS, certain indemnification provisions in favor of LS and customary covenants (including limitations on other debt, liens, acquisitions, investments and dividends), and events of default (including payment defaults, breaches of covenants, a material impairment in LS’s security interest or in the collateral, and events relating to bankruptcy or insolvency). The Receivables Financing Agreement can be terminated by either party upon written notice or by LS upon the occurrence of certain events including the Company’s default.

NOTE 4 —Promissory Note

On February 21, 2025, the Company entered into a note purchase agreement (the “Purchase Agreement”) with Streeterville Capital, LLC (the “Lender”) pursuant to which the Company issued and sold to the Lender a promissory note in the original principal amount of $3,300 (the “Note”).

The Purchase Agreement

Pursuant to the terms of the Purchase Agreement, until all of the Company’s obligations under the Note and all other transaction documents are paid and performed in full, the Company agreed to comply with certain covenants, including but not limited to the following: (i) compliance with its filing requirements under the Securities Exchange Act of 1934, as amended, (ii) maintaining the Company’s listing on a national securities exchange, and (iii) refraining from making any Restricted Issuances (as defined in the Purchase Agreement and described below) without the Lender’s prior written consent, which consent may be granted or withheld in the Lender’s sole discretion.

Subject to certain customary exceptions set forth in the Purchase Agreement, Restricted Issuances include the incurrence or guaranty of any debt obligations other than trade payables in the ordinary course of business, the issuance of any convertible securities in which the number of shares that may be issued pursuant to a conversion right, or the conversion price, varies with the market price of the Company’s common stock, the issuance of any securities with reset provisions and the issuance of any securities in connection with Section 3(a)(9) exchange, a Section 3(a)(10) settlement, or any other similar settlement or exchange. Restricted Issuances do not include ATM facilities, commercial bank loans or lines of credit, leases, grants pursuant to the Company’s incentive plans, and change-in-control transactions that result in full repayment of the Note upon consummation.

The Purchase Agreement also contains a “most favored nation” clause. Under this provision, for as long as the Note remains outstanding, if the Company issues any debt security with more favorable economic terms or conditions not similarly provided to the Lender, the Company must notify the Lender. At the Lender’s option, such favorable terms will become part of the Note and related transaction documents.

The Note

The Note carries an original issue discount of $270, and the Company agreed to pay $30 to the Lender to cover its legal fees, accounting costs, due diligence, monitoring, and other transaction costs, each of which was deducted from the proceeds of the Note received by the Company resulting in a purchase price of $3,000 received by the Company. The Company incurred additional issuance costs of approximately $210, which consisted of legal costs and placement fees.

Since the Note remained outstanding on the 90-day anniversary of the issuance, the Company incurred a one-time monitoring fee of approximately $595 during the three months ended June 30, 2025, which is included in other expense, net, in the Condensed Consolidated Statements of Operations and accrued liabilities in the Condensed Consolidated Balance Sheets.

Interest under the Note accrues at a rate of 9% per annum. The unpaid amount of the Note, any interest, fees, charges, and late fees are due 18 months following the date of issuance. The Company may prepay all or any portion of the outstanding balance of the Note. If the Company elects to prepay the Note in part, it will be required to pay to the Lender an amount in cash equal to 110% of the portion of the outstanding balance the Company elects to prepay.

Commencing six months after the date of issuance of the Note and at any time thereafter until the Note is paid in full, the Lender will have the right to redeem up to $330 under the Note per calendar month. The Company must pay the redeemed amount in cash within three trading days of receiving a redemption notice. On three separate occasions and not more than once every 90 calendar days, the Company may defer any redemptions the Lender could otherwise make during a calendar month, provided, however, that each deferral increases the outstanding balance of the Note by 1%.

At any time following the occurrence of a Major Trigger Event or Minor Trigger Event (each as defined in the Note), the Lender may increase the outstanding balance of the Note by 15% for each occurrence of any Major Trigger Event and 5% for each occurrence of any Minor Trigger Event (the “Trigger Effect”), provided that the Trigger Effect may only be applied three times with respect to Major Trigger Events and three times with respect to Minor Trigger Events.

Subject to certain exceptions described below, if the Company fails to cure a Trigger Event within five trading days following the date of transmission of written demand notice by the Lender, the Trigger Event will automatically become an Event of Default (as defined in the Note). Following the occurrence of any Event of Default, the Lender may, upon written notice to the Company, (i) accelerate the Note, with the outstanding balance of the Note following application of the Trigger Effect (the “Mandatory Default Amount”) becoming immediately due and payable in cash, and (ii) cause interest on the outstanding balance of the Note beginning on the date the applicable Event of Default occurred to accrue at an interest rate equal to the lesser of 22% per annum or the maximum rate permitted under applicable law. However, certain Trigger Events, such as bankruptcy or insolvency, automatically result in an Event of Default, making the outstanding balance immediately payable at the Mandatory Default Amount without notice.

The following table presents the components of the net carrying amount of the Note as of June 30, 2025:

The effective interest rate on the Note was 22.6% for the period from the date of issuance through June 30, 2025. The following table sets forth total interest expense recognized related to the Note:

Subsequent to June 30, 2025, the Company entered into an additional note purchase agreement. See Note 11, Subsequent Events.

NOTE 5 —Stockholders’ Equity

Equity Financing

On April 29, 2024, the Company closed on a capital investment of 350,000 shares of common stock and warrants, as adjusted for the Reverse Stock Split, with a single investor for an aggregate purchase price of $3,850. In connection with the closing, the Company incurred approximately $66 in issuance costs, which was offset against the proceeds.

Each warrant has an exercise price of $11.00 per share, as adjusted for the Reverse Stock Split, is immediately exercisable, will expire in five years from the date of issuance, and is subject to customary adjustments for certain transactions affecting the Company’s capitalization. The warrants may not be exercised if the aggregate number of shares of common stock beneficially owned by the investor subsequent to the exercise exceeds the specified beneficial ownership limitation provided therein (which is currently 9.99% and may be adjusted upon advance notice).

On May 12, 2025, the Company closed on a capital investment of 1,100,000 shares of common stock and 550,000 warrants with two investors for an aggregate purchase price of $1,375. In connection with the closing, the Company incurred approximately $169 in issuance costs, which was offset against the proceeds.

Each warrant has an exercise price of $1.3864 per share, is immediately exercisable, will expire in five years from the date of issuance, and is subject to customary adjustments for certain transactions affecting the Company’s capitalization. The warrants may not be exercised if the aggregate number of shares of common stock beneficially owned by the investor subsequent to the exercise exceeds the specified beneficial ownership limitation provided therein (which is currently 9.99% and 4.99% and may be adjusted upon advance notice).

ATM Offering

On August 6, 2024, the Company entered into a sales agreement (the “Sales Agreement”) with Roth Capital Partners, LLC (“Roth”). Pursuant to the Sales Agreement, the Company may sell, at its option, shares of common stock through Roth, as sales agent. Sales of shares of the Company’s common stock made pursuant to the Sales Agreement are being made under the Registration Statement on Form S-3 filed on April 9, 2024 (File No. 333-278577), which was declared effective by the SEC on May 3, 2024. Subject to the terms and conditions of the Sales Agreement, Roth may sell the shares, if any, only by methods deemed to be an “at the market” offering as defined in Rule 415(a)(4) promulgated under the Securities Act. Roth will be entitled to compensation at a commission rate of 3% of the gross sales price per share sold through it under the Sales Agreement. The Company agreed to provide Roth with customary indemnification and contribution rights, including for liabilities under the Securities Act. In addition, the Company is required to reimburse Roth for certain specified expenses in connection with entering into the Sales Agreement.

The Company has no obligation to sell shares under the Sales Agreement, but it may do so from time to time. During the three and six months ended June 30, 2025, a total of 2,130,437 and 3,480,277 shares of common stock, respectively, were sold under the Sales Agreement for net proceeds of $4,498 and $8,229, respectively, after payment of commission fees and other related expenses of $139 and $258, respectively. As of June 30, 2025, the Company has completed its sales of shares of common stock under the Sales Agreement and the ATM program has been terminated.

Shareholder Rights Plan

On April 21, 2025, the Board declared a dividend of one preferred share purchase right (“Right”) for each outstanding share of common stock, par value $0.001 per share, of the Company, and adopted a stockholder rights plan, as set forth in the Rights Agreement, dated as of April 21, 2025 (the “Rights Agreement”), by and between the Company and Equiniti Trust Company, LLC, a New York limited liability company, as rights agent. The dividend is payable to stockholders of record of the Company as of the close of business on May 2, 2025.

Each Right will allow its holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock (the “Preferred Shares”), par value $0.001 per share, for $4.00 (the “Purchase Price”), once the Rights become exercisable. The Purchase Price payable, and the number of Preferred Shares or other securities or other property issuable upon exercise of the Rights will be subject to adjustment from time to time to prevent dilution in the event of a stock dividend on, or a subdivision, combination or reclassification of, the Preferred Shares. The Rights are exercisable only if a person or group acquires 15.5% or more of the Company’s outstanding common stock (an amount of “less than 20%” in the case of a passive institutional investor as described in the Rights Plan), commences tender or exchange offer, or a similar event, as described in detail in the Purchase Agreement.

NOTE 6 —Stock-Based Compensation

Stock-based compensation expense is as follows:

Stock-based compensation in Cost of Revenues relates to employees who focus on supply chain management.

Stock Options

Stock option activity for the six months ended June 30, 2025, is set forth in the table below:

As of June 30, 2025, there was approximately $973 of unamortized stock-based compensation cost related to unvested stock options, which is expected to be recognized over a weighted average period of 1.44 years.

Restricted Stock Units

Restricted Stock Unit (“RSU”) activity for the six months ended June 30, 2025, is set forth in the table below:

NOTE 7 —Income Taxes

For the three months ended June 30, 2025, and 2024, the Company recorded provisions for income taxes of $139 and $37, respectively. For the six months ended June 30, 2025, and 2024, the Company recorded provisions for income taxes of $271 and $162, respectively. The Company’s effective income tax rate is negative 4.0% for the six months ended June 30, 2025, compared to negative 1.7% for the six months ended June 30, 2024. The effective tax rate is higher than the U.S. federal statutory tax rate primarily as a result of the Company’s full valuation allowance in the United States and foreign income taxes paid in China and India.

The Company’s material income tax jurisdictions are the United States (federal and California), China and India. As a result of net operating loss and credit carryforwards, the Company is subject to audit for tax years 2017 and forward for federal and 2015 and forward for California purposes. The China and India tax years are open under the statute of limitations from 2014 and 2020, respectively, and forward.

The Company is subject to ongoing tax examinations of its tax returns by the Internal Revenue Service and other tax authorities in various jurisdictions. In accordance with the guidance on the accounting for uncertainty in income taxes, the Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. These assessments can require considerable estimates and judgments. As of June 30, 2025, the gross amount of unrecognized tax benefits was approximately $1,507. If the Company’s estimates of income tax liabilities prove to be less than the ultimate assessment, then a further charge to expense would be required. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period in which we determine the liabilities are no longer necessary. The Company does not anticipate any material changes to its uncertain tax positions during the next twelve months.

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted into law. With the passing of this tax legislation, the most notable corporate tax issue that impacts the Company is the change to IRC §174. Since 2022, the Company has been required to capitalize U.S. and foreign research and development expenditures in accordance with IRC §174 and amortize those costs over 5 years for U.S. costs and 15 years for foreign costs. The new legislation will no longer require U.S. research and development costs to be capitalized; however, foreign costs will continue to be capitalized and amortized over 15 years. U.S. costs that were capitalized in tax years 2022 through 2024 can be expensed in 2025 or over a two-year period, 2025 and 2026. Since the legislation was enacted subsequent to June 30, 2025, there was no accelerated deduction for prior year U.S. capitalized costs during the period ended June 30, 2025. The Company is currently evaluating the impact the adoption of the OBBBA will have on its condensed consolidated financial statements.

NOTE 8 —Commitments and Contingencies

Purchase Commitments

The aggregate amount of noncancelable purchase orders as of June 30, 2025, and December 31, 2024, was approximately $15,959 and $15,753, respectively, and were related to the purchase of inventory and components for the Company’s devices, and certification services.

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 between 2025 and 2033. Royalty expense for the three months ended June 30, 2025, and 2024 was $201 and $252, respectively. Royalty expense for the six months ended June 30, 2025, and 2024 was $434 and $482, respectively. Royalty expense is included in Cost of Revenues. The Company may be required to pay additional royalties to additional patent holders and technology providers on future products.

General litigation

The Company is involved in various 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 consolidated financial position, results of operations, or cash flows.

AJP and Orbic Litigation

On April 24, 2025, AJP Holding Company, LLC (“AJP”) on behalf of itself and Orbic North America, LLC (“Orbic”), filed a complaint in the Delaware Court of Chancery against the Company and directors Mike Mulica, James Cassano, Peter Liu, and Jack Steenstra (the “Complaint”). The Complaint alleged that the individual defendants breached their fiduciary duties and seeks, among other relief, a declaration to that effect and an injunction prohibiting enforcement of certain provisions of the Company’s amended and restated bylaws (the “Bylaws”) in connection with the purported notice of nomination (the “Notice”) of proposing a competing slate of directors for election at the Company’s 2025 annual meeting, as more fully described in the Complaint. The Notice was submitted on the evening of Thursday, March 20, 2025—fewer than two business days before the nomination deadline of Saturday, March 22, 2025—and was determined to be deficient for failing to include all information required under the Bylaws.

At that time, AJP beneficially owned approximately 21.5% of the Company’s outstanding common stock. Its sole manager, Jeffrey Wang, served as a director of the Company prior to the 2025 annual meeting of stockholders. Orbic, which is a competitor of the Company and an affiliate of Reliance Communications, LLC (“Reliance”), exercises full voting control over AJP’s shares pursuant to an irrevocable proxy agreement. The Company and Reliance are currently involved in litigation in the United States District Court for the Eastern District of New York (Case No. 24-CV-4433), in which each party has asserted claims against the other arising out of allegations by Reliance regarding purported intellectual property violations by the Company, which the Company disputes. On March 18, 2025, Orbic, AJP, and certain affiliates filed a Schedule 13D announcing the formation of a group under Section 13 of the Securities Exchange Act of 1934.

Orbic and AJP also filed a motion for expedited proceedings with their Complaint. The Delaware Court of Chancery granted the motion for expedited proceedings on May 2, 2025.

On May 11, 2025, the Company’s board of directors determined it was advisable and in the best interests of Sonim to waive the deficiency in the Notice rather than to engage in a protracted litigation. On the same day, Sonim’s counsel notified Orbic’s counsel of the same, thereby rendering the litigation moot. On June 2, 2025, the Complaint was dismissed without prejudice.

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 the Company’s products 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 further action by the Company.

NOTE 9—Net Income (Loss) Per Share

The following table sets forth the computation of the Company’s basic and diluted net loss per share. Share amounts for the periods ended June 30, 2024, have been adjusted retrospectively for the Reverse Stock Split.

The potentially dilutive common shares that were excluded from the calculation of diluted net loss per share because their effect would have been antidilutive are as follows. Share amounts for the periods ended June 30, 2024, have been adjusted retroactively for the Reverse Stock Split.

Additional warrants and shares of the Company’s common stock were issued subsequent to June 30, 2025. See Note 11, Subsequent Events.

NOTE 10 —Entity Level Information

NOTE 11—Subsequent Events

Asset Purchase Agreement

On July 17, 2025, the Company entered into the Asset Purchase Agreement by and among the Company, the Buyer, the Seller Representative named in the Asset Purchase Agreement, and the Parent, solely for the purpose of guaranteeing complete payment and performance obligations of the Buyer contained in the Asset Purchase Agreement.

Pursuant to the Purchase Agreement, the Buyer agreed to acquire substantially all assets of the Company and its subsidiaries related to the Company’s enterprise 5G solutions business, including rugged handsets, smartphones, wireless internet devices, software, services, and accessories (collectively, the “Business”) for a purchase price of $15,000 in cash, subject to (i) customary working capital, indebtedness and transaction expense adjustments (referred to in the Asset Purchase Agreement as the “Adjustment Amount,” which may be a positive or a negative number) and (ii) up to $5,000 in the form of an earn-out payment (the “Earn-Out Payment”), if earned.

Earn-Out

The Earn-Out Payment, if any, will be determined based on the performance of the Business during the twelve-month period beginning July 1, 2025, and ending June 30, 2026. If, during such period, the Business generates Net Revenue (as defined in the Asset Purchase Agreement) in excess of $70,000, the Company will be entitled to receive an amount equal to 50% of the Net Revenue above such threshold, calculated in accordance with the terms of the Asset Purchase Agreement, provided that the Earn-Out Payment will not exceed $5,000. For purposes of the Asset Purchase Agreement, “Net Revenue” generally means the gross revenue of the Business determined in accordance with U.S. generally accepted accounting principles (“GAAP”) minus (a) customary trade, quantity and cash discounts actually taken; (b) credits, allowances, rebates and chargebacks for returns, rejections, damaged goods and billing errors; (c) outbound freight, insurance, customs duties and other transportation charges directly related to such sales; (d) sales, value-added, use and similar taxes (other than income taxes) collected from customers and remitted to the appropriate taxing authority; and (e) any other items that, in accordance with GAAP, are specifically and solely deductible from gross revenue to arrive at net revenue.

Reverse Merger

The Asset Purchase Agreement permits the Company to pursue a reverse merger (“RTO”) with the currently anticipated target or an alternative target, provided that any such transaction is complementary to and not a substitute for the transactions contemplated by the Asset Purchase Agreement.

No Solicitation and Change of Recommendation

The Asset Purchase Agreement includes covenants requiring the Company not to, directly or indirectly (i) solicit, initiate, knowingly encourage, or knowingly induce any Alternative Transaction (as defined in the Asset Purchase Agreement), (ii) engage in discussions or negotiations regarding any Alternative Transaction, or (iii) enter into any letter of intent, term sheet, memorandum of understanding, or other agreement relating to any Alternative Transaction. However, prior to the obtaining of the stockholder approval of the Asset Purchase Agreement (the “Stockholder Approval”), a customary “fiduciary out” provision allows the Company, under certain specified circumstances, to provide information to, and participate in discussions and engage in discussions or negotiations with, third parties with respect to an acquisition proposal if the Company complied with certain notice and other requirements and the board of directors of the Company (or the Special Committee, as applicable) determines in good faith (in each case after consultation with its outside legal counsel and financial advisors), taking into account the legal, financial, regulatory and other aspects of such proposal, that such proposal would be more favorable to the Company’s stockholders from a financial point of view than the consummation of the Asset Purchase Agreement and is reasonably capable of being consummated (a “Superior Proposal”). Negotiations related to an RTO are expressly excluded from the no-solicitation covenant.

Closing Conditions

The completion of the Asset Purchase Agreement is subject to the satisfaction of certain closing conditions, including (i) the Stockholder Approval, (ii) accuracy of the representations and warranties of the parties, (iii) the absence of any order, injunction or law prohibiting consummation of the Asset Purchase Agreement and (iv) receipt by the Company of certain third-party consents. The consummation of the Asset Purchase Agreement is not subject to any financing condition.

Termination; Termination Fee

The Asset Purchase Agreement may be terminated in certain circumstances, including:

The Company will be obligated to pay to the Buyer an amount equal to the transaction expenses reasonably incurred by the Buyer and its affiliates, plus a termination fee equal to $1,000 within three business days following the termination of the Asset Purchase Agreement, if the latter is terminated because of:

Other Terms

The Asset Purchase Agreement contains customary representations and warranties of the parties. Additionally, the Company has agreed to certain covenants, including, among others, (i) covenants relating to the conduct of its business during the interim period between the execution of the Asset Purchase Agreement and its consummation and (ii) not to engage in specified types of transactions or take specified actions during such period unless agreed to in writing by the Buyer.

Registered Public Offering

On July 2, 2025, the Company consummated a best-efforts public offering (the “Offering”) of 7,400,000 shares of its common stock at a public offering price of $0.75 per share. In connection with the Offering, the Company entered into a securities purchase agreement with certain investor signatories thereto for the purchase of shares of common stock described above.

Roth (the “Placement Agent”) served as the exclusive placement agent in connection with the Offering. The Company paid the Placement Agent a cash fee of 7.0% of the aggregate gross proceeds raised at the closing of the Offering, and reimbursement of certain expenses and legal fees in the amount of $100. The Company also issued to designees of the Placement Agent warrants to purchase up to an aggregate of 208,875 shares of Common Stock (the “Placement Agent Warrants”). The Placement Agent Warrants have an exercise price of $0.75 per share, are not exercisable until January 2, 2026, and expire on July 2, 2030. The exercise prices of the Placement Agent Warrants are subject to appropriate adjustment in the event of stock dividends, stock splits, stock combinations, reorganizations or similar events affecting the Common Stock. Subject to limited exceptions, a holder of Placement Agent Warrants will not have the right to exercise any portion of its Warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of common stock in excess of 4.99% (or, upon election by a holder prior to the issuance of any Warrants, 9.99%) of the shares of common stock then outstanding. At the holder’s option, upon notice to the Company, the holder may increase or decrease this beneficial ownership limitation not to exceed 9.99% of the shares of Common Stock then outstanding. The Purchase Agreement contains customary representations, warranties, and covenants by the Company. It also provides for customary indemnification for losses or damages arising out of or in connection with the Offering, including for liabilities under the Securities Act, other obligations of the parties and termination provisions.

The shares of common stock and the Placement Agent Warrants described above and the underlying shares of common stock were offered pursuant to a Registration Statement on Form S-1, as amended (File No. 333-288221), which was declared effective by the SEC on June 30, 2025.

The net proceeds of the Offering are approximately $4,800, after deducting the Placement Agent fees and expenses and other estimated offering expenses payable by the Company. The Company used the net proceeds of the Offering for overall business strategy, for working capital purposes and for general corporate purposes.

July Purchase Agreement

On July 11, 2025, the Company entered into a note purchase agreement (the “July Purchase Agreement”) with Streeterville Capital, LLC (the “Lender”) pursuant to which the Company issued and sold to the Lender a promissory note in the original principal amount of $2,755 (the “July Note”).

July Purchase Agreement

Pursuant to the terms of the July Purchase Agreement, until all of the Company’s obligations under the July Note and all other transaction documents are paid and performed in full, the Company agreed to comply with certain covenants, including but not limited to the following: (i) compliance with its filing requirements under the Securities Exchange Act of 1934, as amended, (ii) maintaining the Company’s listing on a national securities exchange, and (iii) refraining from making any Restricted Issuances (as defined in the July Purchase Agreement and described below) without the Lender’s prior written consent, which consent may be granted or withheld in the Lender’s sole discretion.

Subject to certain customary exceptions set forth in the Purchase Agreement, Restricted Issuances include the incurrence or guaranty of any debt obligations other than trade payables in the ordinary course of business, the issuance of any convertible securities in which the number of shares that may be issued pursuant to a conversion right, or the conversion price, varies with the market price of the Company’s common stock, the issuance of any securities with reset provisions and the issuance of any securities in connection with Section 3(a)(9) exchange, a Section 3(a)(10) settlement, or any other similar settlement or exchange. Restricted Issuances do not include ATM facilities, commercial bank loans or lines of credit, leases, grants pursuant to the Company’s incentive plans, and change-in-control transactions that result in full repayment of the Note upon consummation.

The July Purchase Agreement also contains a “most favored nation” clause. Under this provision, for as long as the July Note remains outstanding, if the Company issues any debt security with more favorable economic terms or conditions not similarly provided to the Lender, the Company must notify the Lender. At the Lender’s option, such favorable terms will become part of the Note and related transaction documents.

July Note

The July Note carries an original issue discount of $225, and the Company agreed to pay $30 to the Lender to cover its legal fees, accounting costs, due diligence, monitoring, and other transaction costs, each of which was deducted from the proceeds of the July Note received by the Company resulting in a purchase price of $2,500 received by the Company. The Company expects to incur additional issuance costs of approximately $210, which consists of legal costs and placement fees.

Additionally, if the July Note remains outstanding on the 90-day anniversary of the issuance, the Company will incur a one-time monitoring fee equal to the difference between (i) the outstanding balance of the Note divided by 0.85 (as minuend), and (ii) the outstanding balance of the Note (as subtrahend).

Interest under the July Note accrues at a rate of 9% per annum. The unpaid amount of the July Note, any interest, fees, charges, and late fees are due 18 months following the date of issuance. The Company may prepay all or any portion of the outstanding balance of the July Note. If the Company elects to prepay the July Note in part, it will be required to pay to the Lender an amount in cash equal to 110% of the portion of the outstanding balance the Company elects to prepay. In addition, any time the Company receives any money in connection with any fundraising or financing transaction (including, but not limited to, any warrant exercises, “at the market” financing, equity line of credit or debt financing), it must immediately make a mandatory prepayment to the Lender in an amount equal to the lesser of (a) 33% of the amount raised in such transaction, and (b) the total outstanding balance due under the July Note as of the closing date of such financing, payable within two trading days of receiving such amount.

Commencing six months after the date of issuance of the July Note and at any time thereafter until the July Note is paid in full, the Lender will have the right to redeem up to $275 under the July Note per calendar month. The Company must pay the redeemed amount in cash within three trading days of receiving a redemption notice. On three separate occasions and not more than once every 90 calendar days, the Company may defer any redemptions the Lender could otherwise make during a calendar month, provided, however, that each deferral increases the outstanding balance of the July Note by 1%.

At any time following the occurrence of a Major Trigger Event or Minor Trigger Event (each as defined in the July Note), the Lender may increase the outstanding balance of the July Note by 15% for each occurrence of any Major Trigger Event and 5% for each occurrence of any Minor Trigger Event (the “Trigger Effect”), provided that the Trigger Effect may only be applied three times with respect to Major Trigger Events and three times with respect to Minor Trigger Events.

Subject to certain exceptions described below, if the Company fails to cure a Trigger Event within five (5) trading days following the date of transmission of written demand notice by the Lender, the Trigger Event will automatically become an Event of Default (as defined in the July Note). Following the occurrence of any Event of Default, the Lender may, upon written notice to the Company, (i) accelerate the July Note, with the outstanding balance of the Note following application of the Trigger Effect (the “Mandatory Default Amount”) becoming immediately due and payable in cash, and (ii) cause interest on the outstanding balance of the July Note beginning on the date the applicable Event of Default occurred to accrue at an interest rate equal to the lesser of 22% per annum or the maximum rate permitted under applicable law. However, certain Trigger Events, such as bankruptcy or insolvency, automatically result in an Event of Default, making the outstanding balance immediately payable at the Mandatory Default Amount without notice.

Security Agreements

The Company’s obligations under the Note are secured by all of the Company’s assets, including its intellectual property, pursuant to a security agreement and intellectual property security agreement entered into by the Company in favor of the Lender on July 11, 2025. Pursuant to these agreements, the Company granted to the Lender a first-position security interest in all right, title, interest, claims and demands of the Company in and to certain property including, but not limited to: all equity in all wholly-owned or partially owned subsidiaries, all goods and equipment and all inventory, and certain patents, trademarks, and other intellectual property, as more fully detailed therein.

Additional Receivables Financing Agreement

On August 7, 2025, the Company entered into a non-recourse factoring agreement with Tradewind GmbH (the “Factor”). Under the terms of the agreement, the Company has committed to sell eligible accounts receivable from designated international customers to the Factor on a continuing basis, subject to individual credit limits and other conditions specified in the agreement.

The factoring arrangement provides for a maximum facility of €3,000, with a financing rate of 85% of the face value of qualified receivables. The Company is able to receive an advance on such receivables, less applicable fees and reserves. Factoring fees vary based on the payment terms of the underlying receivables and range from 0.55% to 1.65% of the invoice amount, with an additional late fee assessed on unpaid balances after 95 days. Interest is equal to the greater of 4.00% or EURIBOR + 3.50%. The Factor assumes the credit risk of purchased receivables, subject to specified exclusions and conditions. The agreement has an initial 12-month term and automatically renews unless terminated in accordance with its terms.
