Notes to the Consolidated Financial Statements

(Unaudited)

1. The Company

Smith Micro Software, Inc. (“Smith Micro” or “the Company”) provides software solutions that simplify and enhance the mobile experience to some of the leading wireless service providers around the globe. From delivering Digital Familly LifestyleTM solutions to providing powerful voice messaging capabilities, the Company strives to enrich today’s connected lifestyles while creating new opportunities to engage consumers via smartphones and consumer Internet of Things (“IoT”) devices. Smith Micro’s portfolio includes family safety software solutions to support families in the digital age and a wide range of products for creating, sharing, and monetizing rich content, such as visual voice messaging, retail content display optimization and performance analytics on any product set.

Smith Micro’s solution portfolio is comprised of proven products that enable its customers to provide:

•In-demand digital services that connect today’s digital lifestyle, including family location services, parental controls, and consumer IoT devices to mobile consumers worldwide;

•Easy visual access to voice messages on mobile devices through visual voicemail and voice-to-text transcription functionality; and

•Strategic, consistent, and measurable digital demonstration experiences that educate retail shoppers, create awareness of products and services, drive in-store sales, and optimize retail experiences with actionable analytics derived from in-store customer behavior.

On April 3, 2024, the Company filed a certificate of amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to effect a one-for-eight (1:8) reverse stock split of the shares of the Company's common stock, par value $0.001 per share (the "Common Stock"), with an effective time of 11:59 p.m., Eastern Time on April 10, 2024 (the "Reverse Stock Split"). At the effective time, every eight shares of Common Stock, whether issued and outstanding or held by the Company as treasury stock were automatically combined and converted (without any further act) into one share of fully paid and nonassessable Common Stock, with any fractional shares resulting from the Reverse Stock Split rounded up to the nearest whole share. The number of outstanding shares of Common Stock was reduced from approximately 76.8 million shares to approximately 9.6 million shares due to the Reverse Stock Split.

The Reverse Stock Split did not change the Company's authorized shares of Common Stock from 100,000,000 shares or the par value of the Common Stock. Proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise of stock options and the settlement of restricted stock awards and the number of shares authorized and reserved for issuance pursuant to the Company's equity incentive plans (see Note 9). Additionally, there were adjustments to the per share exercise price and the number of shares issuable upon exercise of warrants (see Note 5).

All share and per share amounts for Common Stock (including share amounts underlying convertible securities and the applicable exercise prices of such convertible securities) in these consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split, including reclassifying an amount equal to the reduction in the number of shares of Common Stock at par value to additional paid-in capital.

2. Accounting Policies

Basis of Presentation

The accompanying interim consolidated balance sheet as of June 30, 2024, and the related consolidated statements of operations and stockholders’ equity for the three and six months ended June 30, 2024 and 2023, and the consolidated statements of cash flows for the six months ended June 30, 2024 and 2023, are unaudited. The unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been omitted.

In the opinion of management, the accompanying unaudited consolidated financial statements for the periods presented reflect all adjustments which are normal and recurring, and necessary to fairly state the financial position, results of operations, and cash flows of the Company. These unaudited consolidated financial statements should be read in

Table of Contents

conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 26, 2024 (the "2023 Form 10-K").

Intercompany balances and transactions have been eliminated in consolidation.

Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2024.

New Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Improvements to Reportable Segment Disclosures." This update was issued to improve and enhance reportable segment disclosure requirements. The amendments in this update require annual and interim disclosures on significant segment expenses that are regularly provided to the chief operating decision maker and require annual and interim disclosures on “other segment items” that comprise the difference between segment revenue less segment expense compared to the reported measure of segment profit or loss. In addition, the amendments will require all annual disclosures that are currently required to be reported on an interim basis and requires disclosure of the title and position of the chief operating decision maker and how that position uses the information to assess segment performance and the allocation of resources. ASU 2023-07 also requires entities that have a single reportable segment, such as the Company, to provide all disclosures required in this update and the existing segment disclosures in Topic 280. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of ASU 2023-07 and does not expect them to have a material effect on the consolidated financial statements.

In December 2023, FASB issued ASU 2023-09, "Income Tax Disclosures." ASU 2023-09 was issued to require annual disclosures on specific categories in the income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. Annual disclosures are required on income taxes paid, including the amounts paid for federal, state and foreign taxes and the amount paid in individual jurisdictions if the amount is equal to or greater than 5% of total income taxes paid (net of refunds received). Additional annual disclosures are required on pre-tax income from continuing operations and income tax expense, disaggregated by domestic and foreign amounts. The amendments in this update are effective for fiscal years beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of ASU 2023-09 and does not expect them to have a material effect on the consolidated financial statements.

Reclassifications

Certain reclassifications have been made to the prior year financial statements to conform to the current presentation.

3. Going Concern

The Company's financial statements have been presented on the basis that it is a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. In connection with preparing interim consolidated financial statements for the three and six months ended June 30, 2024, certain conditions in the Company's evaluation, considered in the aggregate, have raised substantial doubt about the Company's ability to continue as a going concern within one year from the date that the financial statements are issued, which has not been alleviated. The evaluation considered the Company's financial condition, including its liquidity sources, funds necessary to maintain the Company's operations considering the current financial condition, obligations, and other expected cash flows, and negative financial trends of recurring operating losses and negative cash flows.

The Company has no outstanding debt and is continuing operations and generating revenues in the normal course of business, however the Company is dependent, to an extent, on the timing of subscriber and revenue growth for its products and the related cash generation from that growth and/or the ability to obtain the necessary capital to meet its obligations and fund its working capital requirements to maintain normal business operations. Management believes that the actions presently being taken to implement the Company's business plan to expand subscriber growth, including dynamic marketing campaigns, to acquire new customers and to expand its offerings to existing customers to generate increased revenues, and, if necessary, to raise additional capital will support the Company's operations; as such the financial statements do not include any adjustments that may be necessary if the Company is unable to continue as a going concern. The Company believes that it would be able to raise additional funds as necessary, through public or private equity offerings, including via accessing its currently effective shelf registration or by filing one or more additional registration statements, debt financings, or a combination of these funding sources as evidenced by the Company historically being able to complete debt and equity financings. However it may not be able to secure such incremental capital in a timely manner

Table of Contents

or on favorable terms, if at all. In order to preserve liquidity, the Company may also take one or more of the following additional actions:

•Implement additional restructuring and cost reductions,

•Secure a revolving line of credit, if available,

•Dispose of one or more product lines and/or,

•Sell or license intellectual property.

While management believes that the Company’s plans for growing revenue and the other potential actions available to it would alleviate the conditions that raise substantial doubt, these strategies are not entirely within the Company’s control and cannot be assessed as being probable of occurring.

4. Common Stock

Minimum Bid Price Requirement and Reverse Stock Split

On December 27, 2023, the Company received a notice (the "Notice") from the Nasdaq Stock Market ("Nasdaq") that the Company was not in compliance with the $1.00 minimum bid price requirement for continued listing, as set forth in Nasdaq Listing Rule 5550(a)(2) (the "Minimum Bid Price Requirement"), as the closing bid price of the Company’s Common Stock had been below $1.00 per share for more than thirty (30) consecutive business days as of the date of the Notice.

As previously noted, the Company undertook the Reverse Stock Split, which became effective April 10, 2024 at 11:59 pm Eastern time, to enable the Company to regain compliance with the Minimum Bid Price Requirement. On April 29, 2024, the Company received notice from Nasdaq that it had regained compliance with the Minimum Bid Price Requirement, and the matter is now closed.

May 2024 Registered Direct Offering & Private Placement

On May 10, 2024, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with certain institutional and accredited investors (the “Purchasers”) relating to the registered direct offering and sale of an aggregate of 1,065,000 shares of the Company’s Common Stock at an offering price of $2.15 per share of Common Stock and pre-funded warrants (“Pre-Funded Warrants”) to purchase up to 845,000 shares of Common Stock (the “Registered Direct Offering”). The Pre-Funded Warrants were purchased at a price of $2.149 per underlying share and have an exercise price of $0.001 per share and can be exercised at any time after their original issuance until such Pre-Funded Warrants are exercised in full. The shares of Common Stock and Pre-Funded Warrants (including the shares of Common Stock underlying the warrants) were offered by the Company pursuant to a prospectus supplement dated May 10, 2024, and accompanying prospectus dated May 12, 2022, in connection with a takedown from the Company’s shelf registration statement on Form S-3 (File No. 333-264667), which was declared effective by the SEC on May 12, 2022.

In a private placement on May 14, 2024, concurrent with the Registered Direct Offering, the Company also sold to the Purchasers unregistered warrants (the “Common Warrants”) to purchase up to an aggregate of 1,910,000 shares of Common Stock (the “Private Placement”). Each unregistered Common Warrant has an exercise price of $2.34 per share, is exercisable at any time beginning November 14, 2024 and will expire November 14, 2029. Both the Registered Direct Offering and the Private Placement closed on May 14, 2024.

Roth Capital Partners, LLC (“Roth”) acted as the exclusive placement agent for the Registered Direct Offering and the Private Placement pursuant to a placement agency agreement (the “Placement Agency Agreement”) dated May 10, 2024, by and between the Company and Roth, and a related engagement letter with Roth. Pursuant to the Placement Agency Agreement, on May 14, 2024 the Company issued to Roth warrants to purchase up to 133,700 shares of Common Stock (the “Placement Agent Warrants”), which represented 7.0% of the aggregate number of shares of Common Stock and Pre-Funded Warrants sold in the Registered Direct Offering. The Placement Agent Warrants are exercisable at any time beginning November 14, 2024, have an exercise price equal to $2.86, and expire November 16, 2026.

The shares of Common Stock underlying the Common Warrants and the Placement Agent Warrants (collectively referred to herein as the “Warrants”) were registered on a registration statement on Form S-1 (File No. 333-280542) filed with the SEC on June 27, 2024, which was declared effective by the SEC on July 10, 2024. Shares of Common Stock issued by the Company upon exercise of the Warrants may be resold by the holders pursuant to the prospectus dated July 11, 2024. The filings made by the Company in connection with the potential resale of the Common Stock underlying the Warrants were filed within the time period agreed by the parties in the Purchase Agreement.

Table of Contents

The net cash proceeds to the Company, after deducting offering related expenses was $3.4 million. The Pre-Funded Warrants, Common Warrants, and Placement Agent Warrants were all assessed and recorded as equity instruments.

During the three and six months ended June 30, 2024, no Pre-Funded Warrants, Common Warrants or Placement Agent Warrants from the Registered Direct Offering and Private Placement were exercised.

The 845,000 shares of the Company's Common Stock underlying the above described Pre-Funded Warrants are not included in the number of issued and outstanding shares of the Company's Common Stock outstanding as reported on the consolidated balance sheet, though they are included in the Company's weighted average outstanding Common Stock in the calculation of basic and diluted net loss per share, as further disclosed in Note 8.

5. Warrant Liabilities

On August 11, 2022, the Company issued warrants (the "Notes Warrants") to purchase Common Stock in conjunction with a notes and warrants offering (the "Notes and Warrants Offering"), at an initial fair value of $3.8 million. The senior secured convertible notes (the "Notes") that the Company sold in the Notes and Warrants Offering were retired at maturity at December 31, 2023. The exercise price of and number of shares underlying the Notes Warrants were immediately proportionately adjusted pursuant to the Reverse Stock Split to $26.80 and 279,851 shares, respectively, and on May 2, 2024, the exercise price for each of the Notes Warrants was further adjusted to $2.06 in accordance with their terms.

The Company issued additional warrants (the "Additional Warrants") to purchase Common Stock on August 12, 2022 in conjunction with a registered direct offering for the sale of shares of the Company's Common Stock and the Additional Warrants. The Additional Warrants do not reprice further beyond the immediate proportionate adjustments to the per share exercise price and number of shares issuable of $21.20 and 141,509 shares, respectively, that occurred upon and as a result of the Reverse Stock Split.

All changes in the fair value of the Notes Warrant and Additional Warrants liabilities are recognized in the Company's consolidated statements of operations until they are either exercised or expire. Since their issuance, none of the Notes Warrants or Additional Warrants have been exercised. The Notes Warrants and Additional Warrants are not traded in an active securities market and, as such, the estimated fair value is determined by using a Black-Scholes option pricing model which considers the likelihood of repricing adjustments and utilizes assumptions noted in the following table. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on the historical volatility over the expected term of the warrants. The Company has no reason to believe future volatility over the expected remaining life of the Notes Warrants and Additional Warrants is likely to differ materially from historical volatility. Expected life is based on the term of the applicable warrants. Below are the specific assumptions utilized (unaudited, except for December 31, 2023):


Notes Warrants	June 30, 2024			December 31, 2023
Common Stock market price	$	2.21		$	6.64

6. Fair Value of Financial Instruments

Table of Contents

The Company measures and discloses fair value measurements as required by FASB ASC Topic No. 820, Fair Value Measurements and Disclosures.

Fair value is an exit price, representing the amount that would be received upon the sale of an asset or the amount that would be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

•Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

•Level 2 – Include other inputs that are directly or indirectly observable in the marketplace.

•Level 3 – Unobservable inputs which are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The following table presents information about the financial liabilities that are measured at fair value on a recurring basis at June 30, 2024 and December 31, 2023 (unaudited except for December 31, 2023, in thousands):

7. Goodwill and Intangible Assets

In accordance with FASB ASC Topic No. 350, Intangibles-Goodwill and Other, Smith Micro reviews the recoverability of the carrying value of its single reporting unit goodwill at least annually or whenever events or circumstances indicate a potential impairment. Different judgments relating to the determination of reporting units could significantly affect the testing of goodwill for impairment and the amount of any impairment recognized. Recoverability of goodwill is determined by comparing the estimated fair value of reporting units to the carrying value of the underlying net assets in the reporting units. If the estimated fair value of a reporting unit is determined to be less than the fair value of its net assets, goodwill is deemed impaired, and an impairment loss is recognized to the extent that the carrying value of goodwill exceeds the difference between the estimated fair value of the reporting unit and the fair value of its other assets and liabilities.

During the three months ended March 31, 2024, as a result of the sustained decrease in the Company's Common Stock share price and overall market capitalization subsequent to February 23, 2024, management of the Company concluded that a triggering event occurred, indicating goodwill may be impaired. The Company conducted a quantitative impairment test of its goodwill as of February 29, 2024 and as a result of this interim assessment, the Company recorded a goodwill impairment charge totaling $24.0 million during the three months ended March 31, 2024. The fair value of the reporting unit was determined utilizing level 3 inputs (including estimates of revenue growth, earnings before interest taxes depreciation and amortization ("EBITDA") contribution and discount rates) and a combination of the income approach using the estimated discounted cash flows and a market-based valuation methodology. There were no further goodwill impairment indicators through June 30, 2024. If current projections are not achieved or specific valuation factors outside the Company's control, such as discount rates and continued economic and industry challenges, significantly change, goodwill could be subject to future impairment.

The components of the Company’s intangible assets were as follows for the periods presented (unaudited except for December 31, 2023, in thousands, except for useful life data):

8. Earnings Per Share

The Company calculates earnings per share (“EPS”) as required by FASB ASC Topic No. 260, Earnings Per Share. Basic EPS is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, plus the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method.

The 845,000 shares of the Company's Common Stock issuable upon exercise of the Pre-Funded Warrants, described in Note 4 to these consolidated financial statements, are included in the weighted average outstanding Common Stock in the calculation of basic and diluted net loss per share as the exercise price is non-substantive at $0.001 per share.

For periods with a net loss, the dilutive common stock equivalents are excluded from the diluted EPS calculation. For purposes of this calculation, Common Stock subject to repurchase by the Company, options, warrants (other than the Pre-Funded Warrants), and convertible notes are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive.

The following table sets forth the details of basic and diluted earnings per share (unaudited, in thousands, except per share amounts):

9. Stock-Based Compensation

Stock Plans

On June 18, 2024, the Company's stockholders approved the Company's Amended and Restated Omnibus Equity Incentive Plan (the "OEIP") which amended and restated (and renamed) the Company's 2015 Omnibus Equity Incentive Plan (as previously amended, the "2015 Plan") and increased the number of shares reserved thereunder by 3 million shares. As of June 30, 2024, there were approximately 3.1 million shares available for future grants under the Company’s OEIP. References to the OEIP herein include the 2015 Plan prior to its amendment and restatement. The maximum number of shares available for issuance over the term of the OEIP may not exceed 4.2 million shares.

During the six months ended June 30, 2024, the Company granted 0.3 million shares of restricted stock under the OEIP. There were no shares of restricted stock granted during the three months ended June 30, 2024.

The Company previously maintained a 2005 Stock Option / Stock Issuance Plan (the “2005 Plan”), which was replaced by and upon the adoption of the 2015 Plan. Certain options issued under the 2005 Plan remain outstanding, but no new grants have been made under the 2005 Plan since the adoption of the 2015 Plan.

The OEIP provides for the issuance of full value awards (restricted stock, performance stock, dividend equivalent right or restricted stock units) and partial value awards (stock options or stock appreciation rights) to employees, non-employee members of the Company's Board of Directors and consultants. Any full value award settled in shares will be debited as 1.2 shares, and partial value awards settled in shares will be debited as 1.0 shares against the share reserve. The exercise price per share for stock option grants is not to be less than the fair market value per share of the Company’s Common Stock on the date of grant. The Compensation Committee of the Board of Directors administers the OEIP and determines the vesting schedule at the time of grant. Stock options may be exercisable immediately or in installments, but generally vest over a four-year period from the date of grant. In the event the holder ceases to be employed by the Company, all unvested stock awards terminate, and all vested stock options may be exercised within a period of 90 days following termination of employment. In general, stock options expire ten years from the date of grant. Restricted stock is valued using the closing stock price on the date of the grant. The total value is expensed over the vesting period, which typically ranges from 12 to 48 months, however in the quarters ended March 31, 2024 and September 30, 2023, the Company granted restricted stock awards with tranched vesting periods of two to seven months.

Employee Stock Purchase Plan

The Company has a stockholder approved employee stock purchase plan (“ESPP”), under which substantially all employees may purchase the Company’s Common Stock through payroll deductions at a price equal to 85% of the lower of the fair market values of the stock as of the beginning and end of six-month offering periods. Payroll deductions under the ESPP are limited to 10% of the employee’s compensation and in any calendar year employees may not purchase more than the lesser of $25,000 of stock or 250 shares, as set by the Compensation Committee of the Board of Directors in accordance with the terms of the ESPP. Additionally, no more than 31,250 shares in the aggregate may be purchased under the ESPP.

Stock Compensation Expense

The Company accounts for all stock-based payment awards made to employees and directors based on their fair values and recognized as compensation expense over the vesting period using the straight-line method over the requisite service period for each award as required by FASB ASC Topic No. 718, Compensation-Stock Compensation.

Table of Contents

Non-cash stock-based compensation expenses related to stock options, restricted stock grants and the ESPP were recorded in the financial statements as follows (unaudited, in thousands):

Total non-cash stock compensation expense	$	1,138	$	1,030	$	2,272	$	1,975

As of June 30, 2024, there was approximately $4.0 million in unrecognized compensation costs related to unvested stock options and restricted stock awards granted under the OEIP and the 2005 Plan. In the second quarter of 2024, vesting of certain restricted stock awards was accelerated in accordance with the terms of the OEIP. As such, an additional $0.1 million of stock compensation expense was recorded in sales and marketing expense in that period.

Stock Options

For the six months ended June 30, 2024, the Company had approximately 9,000 stock options outstanding under the OEIP and 2005 Plan with a weighted average exercise price of $26.89 per share, a remaining weighted average contractual life of 3.4 years and nominal intrinsic value. No options were granted in the six months ended June 30, 2024 or 2023.

Restricted Stock Awards

10. Revenues

Revenue Recognition

In accordance with FASB ASC Topic No. 606, Revenue from Contracts with Customers, the Company recognizes the sale of goods and services based on the five-step analysis of transactions as provided in Topic 606, which requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods and services. For all contracts with customers, the Company first identifies the contract, which usually is established when a contract is fully executed by each party and consideration is expected to be received. Next, the Company identifies the performance obligations in the contract. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. The Company then determines the transaction price in the arrangement and allocates the transaction price, if necessary, to each performance obligation identified in the contract. The allocation of the transaction price to the performance obligations are based on the relative standalone selling prices for the goods and services contained in a particular performance obligation. The transaction price is adjusted for the Company’s estimate of variable consideration which may include certain incentives and discounts, product returns, distributor fees, and storage fees. The Company evaluates the total amount of variable consideration expected to be earned by using the expected value method, as the Company believes this method represents the most appropriate estimate for this consideration, based on historical service trends, the individual contract considerations, and its best judgment at the time. The Company includes estimates of variable consideration in revenues only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company generates the

Table of Contents

majority of its revenue on usage-based fees which are variable and depend entirely on customers’ use of perpetual licenses, transactions processed on the Company’s hosted environment and activity on the Company’s cloud-based service platform.

The Company’s contracts with mobile network operator (“MNO”) customers include promises to transfer multiple products and services. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Smith Micro’s cloud-based services include a software solution license integrated with cloud-based services. Since the Company does not allow its customers to take possession of the cloud-based elements of its software solutions, and since the utility of the license comes from the cloud-based services that the Company provides, Smith Micro considers the software license and the cloud services to be a single performance obligation. The Company recognizes revenue associated with its MNO customers based upon their active subscribers’ access and usage of Smith Micro’s software licenses and cloud-based services on Smith Micro’s platforms or satisfaction of the performance obligations as indicated in the contracts.

Smith Micro has made accounting policy elections to exclude all taxes by governmental authorities from the measurement of the transaction price, and since the Company’s standard payment terms are less than one year, the Company has elected the practical expedient not to assess whether a contract has a significant financing component.

11. Segment, Customer Concentration and Geographical Information

Segment Information

Public companies are required to report financial and descriptive information about their reportable operating segments as required by FASB ASC Topic No. 280, Segment Reporting. The Company has one primary business unit based on how management internally evaluates separate financial information, business activities and management responsibility: Wireless. The Wireless segment includes the Family Safety (which includes SafePath®), CommSuite®, and ViewSpot® families of products.

The Company does not separately allocate operating expenses to these product lines, nor does it allocate specific assets. Therefore, product line information reported includes only revenues.

For the three months ended June 30, 2024, two customers made up 59% and 20% of revenues. For the three months ended June 30, 2023, three customers made up 40%, 37% and 14% of revenues.

For the six months ended June 30, 2024, three customers made up 56%, 19%, and 11% of revenues. For the six months ended June 30, 2023, three customers made up 39%, 37%, and 14% of revenues.

As of June 30, 2024, two customers accounted for 52% and 15% of accounts receivable. As of June 30, 2023, three customers accounted for 39%, 34%, and 15% of accounts receivable.

Geographical Information

During the three and six months ended June 30, 2024 and 2023, the Company operated in two geographic locations: the Americas and Europe, Middle East and Africa ("EMEA"). Revenues attributed to the geographic location of the customers’ bill-to address were as follows (unaudited, in thousands):

The Company does not separately allocate specific assets to these geographic locations.

12. Commitments and Contingencies

Litigation

The Company may become involved in various legal proceedings arising from its business activities. While management does not believe the ultimate disposition of these matters will have a material adverse impact on the Company’s consolidated results of operations, cash flows, or financial position, litigation is inherently unpredictable, and depending on the nature and timing of these proceedings, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows, or financial position in a particular period.

Other Contingent Contractual Obligations

During its normal course of business, the Company has made certain indemnities, commitments, and guarantees under which it may be required to make payments in connection with certain transactions. These include: indemnities to the Company’s customers pursuant to contracts for the Company’s products and services, including indemnities with respect to intellectual property, confidentiality and data privacy; indemnities to various lessors in connection with facility leases for certain claims arising from use of such facility or under such lease; indemnities to vendors and service providers pertaining to claims based on the negligence or willful misconduct of the Company; indemnities involving the accuracy of representations and warranties in certain contracts; and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware. In addition, the Company has made or may make

Table of Contents

contractual commitments to employees providing for severance payments upon the occurrence of certain prescribed events. The Company may also issue a guarantee in the form of a standby letter of credit as security for contingent liabilities under certain customer contracts. The duration of these indemnities, commitments, and guarantees varies, and in certain cases may be indefinite. The majority of these indemnities, commitments, and guarantees may not provide for any limitation of the maximum potential for future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities, commitments, and guarantees in the accompanying consolidated balance sheets.

13. Leases

The Company leases office space and equipment. The Company determines if a contract is a lease at the inception of the arrangement and reviews all options to extend, terminate, or purchase its right-of-use assets at the inception of the lease and accounts for these options when they are reasonably certain of being exercised.

Leases with an initial term of greater than twelve months are recorded on the consolidated balance sheet. Lease expense is recognized on a straight-line basis over the lease term.

The Company’s lease contracts generally do not provide a readily determinable implicit rate. For these contracts, the estimated incremental borrowing rate is based on information available at the inception of the lease.

Operating lease costs were $0.4 million and $0.4 million for the three months ended June 30, 2024 and 2023, respectively. For the six months ended June 30, 2024, and 2023, operating lease costs were $0.8 million and $0.8 million, respectively.

During the six months ended June 30, 2024, the Company recognized noncash increases for the right-of-use asset obtained in exchange for new operating lease liabilities due to a lease renewal and entry into a new lease in the amount of $1.0 million. There were no such transactions during the six months ended June 30, 2023. The maturity of operating lease liabilities is presented in the following table (unaudited, in thousands):

14. Income Taxes

The Company accounts for income taxes as required by FASB ASC Topic No. 740, Income Taxes. The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax liabilities against gross deferred tax assets); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies; and (4) future taxable income exclusive of reversing temporary differences and carryforwards.

In assessing whether a valuation allowance is required, significant weight is given to evidence that can be objectively verified. Realization of deferred tax assets is dependent upon the generation of future taxable income. As required by ASC 740, Smith Micro has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets and determined that it was more likely than not that the Company would not realize the deferred tax assets due to the

Company's cumulative losses and uncertain near-term market and economic conditions, which reduce the Company’s ability to rely on projections of future taxable income in assessing the realizability of its deferred tax assets.

After a review of the four sources of taxable income as of June 30, 2024, and after consideration of the Company’s cumulative loss position as of December 31, 2023, the Company will continue to reserve its U.S.-based deferred tax amounts, which total $58.5 million as of June 30, 2024.

The Company is subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. The Company is no longer subject to examination for U.S. federal income tax returns for years before December 31, 2019 and for state income tax returns, the Company is no longer subject to examination for years before December 31, 2018. As of June 30, 2024, the Company had no outstanding tax audits. The outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs. Smith Micro may from time to time be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to the consolidated financial results of the Company. It is the Company’s policy to classify any interest and/or penalties in the consolidated financial statements as a component of income tax expense.

15. Subsequent Events

The Company evaluates and discloses subsequent events as required by FASB ASC Topic No. 855, Subsequent Events. The Topic establishes general standards of accounting for and disclosure of events that occur after the balance sheet date, but before the financial statements are issued or are available to be issued.

•our ability to assimilate acquisitions without diverting management attention and impacting current operations;

•failure to realize the expected benefits of prior acquisitions;

•the availability of third-party intellectual property and licenses needed for our operations on commercially reasonable terms, or at all;

•the difficulty of predicting our quarterly revenues and operating results and the chance of such revenues and results falling below analyst or investor expectations, which could cause the price of our Common Stock to fall; and

The forward-looking statements contained in this Report are made on the basis of the views and assumptions of management regarding future events and business performance as of the date this Report is filed with the Securities and Exchange Commission (the “SEC”). In addition, we operate in a highly competitive and rapidly changing environment; therefore, new risk factors can arise, and it is not possible for management to predict all such risk factors, nor to assess the impact of all such risk factors on our business or the extent to which any individual risk factor, or combination of risk factors, may cause results to differ materially from those contained in any forward-looking statement. We do not undertake any obligation to update these statements to reflect events or circumstances occurring after the date this Report is filed.

Overview

Smith Micro provides software solutions that simplify and enhance the mobile experience to some of the leading wireless service providers around the globe. From delivering Digital Family Lifestyle™ solutions to providing powerful voice messaging capabilities, we strive to enrich today’s connected lifestyles while creating new opportunities to engage consumers via smartphones and consumer IoT devices. Our portfolio includes a wide range of products for creating, sharing, and monetizing rich content, such as visual voice messaging, retail content display optimization and performance analytics on any product set.

We continue to innovate and evolve our business to respond to industry trends and maximize opportunities in emerging markets, such as digital lifestyle services and online safety, “Big Data” analytics, automotive telematics, and the consumer IoT marketplace. The key to our longevity, however, is not simply technological innovation, but our focus on understanding our customers’ needs and delivering value.

In the second quarter of 2024, our revenues declined by 50% to $5.1 million compared to the second quarter of 2023, primarily driven by a $4.5 million decrease in our Family Safety product line, coupled with a $0.5 million decrease in ViewSpot revenues. These revenue declines primarily resulted from the losses of a Family Safety contract with a Tier 1 carrier and a ViewSpot contract during 2023 coupled with decreases associated with legacy Sprint Safe & Found revenue as subscribers are migrating to the T-Mobile network. As a result of the decline in revenues, our gross profit decreased during the second quarter of 2024 to $3.5 million, representing a decrease of $4.2 million as compared to the second quarter of the prior year. Our operating expenses have decreased during the second quarter of 2024 compared to the second quarter of 2023 by approximately $0.5 million, primarily due to quarter-over-quarter reductions in general and administrative costs. The net loss for the second quarter of 2024 was $6.9 million, resulting in a net loss of $0.66 per basic and diluted share.

We currently provide white label Family Safety applications to two Tier 1 wireless carriers in the United States, and believe that we remain strategically positioned to offer our market-leading family safety platform to the majority of U.S. mobile subscribers. We believe that we have an opportunity to increase the respective subscriber bases, and in turn, grow the revenues associated with these Tier 1 carriers. Further, we executed new, multi-year Family Safety agreements with a Tier 1 carrier in Europe in the fourth quarter of 2023 and a U.S.-based carrier in the first quarter of 2024. The new Family Safety solution with the U.S. based carrier launched on our SafePath Global platform during the second quarter of 2024, and associated marketing activities for that product have begun. Additionally, the Family Safety solution for the Tier 1 European carrier is anticipated to launch in the next few months.

Results of Operations

On April 3, 2024, we filed a certificate of amendment to our Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to effect a one-for-eight (1:8) reverse stock split of the shares of the Company's Common Stock, par value $0.001 per share, with an effective time of 11:59 p.m., Eastern Time on April 10, 2024 (the "Reverse Stock Split"). At the effective time, every eight shares of our Common Stock, whether issued and outstanding or held by the Company as treasury stock were automatically combined and converted (without any further act) into one share of fully paid and nonassessable Common Stock, with any fractional shares resulting from the Reverse Stock Split rounded up to the nearest whole share. See further information in Note 1. All shares and per share amounts in this Report have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split.

The table below sets forth certain statements of operations and comprehensive loss data expressed as a percentage of revenues for the three and six months ended June 30, 2024 and 2023. Our historical results are not necessarily indicative of the operating results that may be expected in the future.

Three Months Ended June 30, 2024 Compared to the Three Months Ended June 30, 2023

Revenues. Revenues were $5.1 million and $10.3 million for the three months ended June 30, 2024 and 2023, respectively, representing a decrease of $5.2 million, or 50%. This decrease was primarily related to the loss of revenue from a Family Safety contract with a Tier 1 carrier that concluded during the fourth quarter of 2023 coupled with legacy Sprint Safe & Found revenue declining as legacy Sprint subscribers are migrating to the T-Mobile network. Also contributing to the decrease was a decline in ViewSpot revenue primarily due to one of our contracts concluding as of the end of September 2023.

Cost of revenues. Cost of revenues were $1.6 million and $2.6 million for the three months ended June 30, 2024 and 2023, respectively. This decrease of $1.0 million was primarily due to cost reduction efforts and the period-over-period decline in revenue.

Gross profit. Gross profit was $3.5 million, or 68.7% of revenues, for the three months ended June 30, 2024, compared to $7.7 million, or 75.0% of revenues, for the three months ended June 30, 2023. The decrease of $4.2 million in gross profit was primarily driven by the period-over-period decline in revenues.

Table of Contents

Selling and marketing. Selling and marketing expenses were $2.5 million and $2.6 million for the three months ended June 30, 2024 and 2023, respectively. This decrease of approximately $0.1 million was due to decreases in marketing costs partially offset by increases in stock based compensation expense.

Research and development. Research and development expenses were essentially flat period-over-period at $3.7 million for the three months ended June 30, 2024 and 2023.

General and administrative. General and administrative expenses were $2.7 million and $3.0 million for the three months ended June 30, 2024 and 2023, respectively. This decrease of approximately $0.3 million was primarily related to declines in personnel related costs of approximately $0.1 million and a decrease in occupancy costs of approximately $0.1 million.

Depreciation and amortization. Depreciation expense was $0.1 million for both the three months ended June 30, 2024 and 2023. Amortization expense was $1.5 million for both the three months ended June 30, 2024 and 2023. Amortization expense is recognized based on the pattern of economic benefit expected to be generated from the use of the intangible assets.

Change in fair value of warrant and derivative liabilities. Change in fair value of warrant and derivative liabilities was nominal and $0.4 million for the three months ended June 30, 2024 and 2023, respectively. The total decrease of approximately $0.4 million resulted from valuation related impacts to the warrant and derivative liabilities combined with settlements of the Notes during the three months ended June 30, 2023. The Notes were retired at maturity in December 2023, and thus there were no changes in the fair value of the derivative liability in 2024.

Loss on derecognition of debt. The loss recognized on derecognition of debt was $0.8 million for the three months ended June 30, 2023, resulting from installment payments made on the convertible notes issued under the Note and Stock offering in August 2022 (the "Notes") in the form of shares, and the required derecognition of the net debt position related to that principal balance, including the derivative and discounts. There was nothing commensurate in the three months ended June 30, 2024 as the convertible notes were retired at maturity as of December 31, 2023.

Interest income (expense), net. Interest income, net was nominal for the three months ended June 30, 2024 while interest expense, net was $2.0 million for the three months ended June 30, 2023. The period-over-period change in interest income (expense), net of $2.1 million was primarily related to the amortization of the discount and debt issuance costs and stated interest expense related to the Notes, which were fully retired effective December 31, 2023.

Other (expense) income, net. Other income (expense) net was nominal for both the three months ended June 30, 2024 and 2023.

Provision for income tax expense. Because of our cumulative loss position, the provision for income tax expense consists of state income taxes, foreign tax withholdings, and foreign income taxes for the three months ended June 30, 2024 and 2023. There were no material changes in the period-to-period comparison.

Six Months Ended June 30, 2024 Compared to the Six Months Ended June 30, 2023

Revenues. Revenues were $10.9 million and $21.3 million for the six months ended June 30, 2024 and 2023, respectively, representing a decrease of $10.3 million, or 49%. This decrease was primarily related to declines associated with our Family Safety product line of $9.2 million. The decrease in revenues was primarily associated with the loss of revenue from a Family Safety contract with a Tier 1 carrier that concluded during the fourth quarter of 2023 coupled with legacy Sprint Safe & Found revenue declining as legacy Sprint subscribers are migrating to the T-Mobile network. Also contributing to the period-over-period revenue decrease was a decline in ViewSpot revenue of $0.8 million primarily due to one of our contracts concluding as of the end of September 2023.

Cost of revenues. Cost of revenues were $3.6 million and $5.9 million for the six months ended June 30, 2024 and 2023, respectively. This decrease of approximately $2.3 million was primarily due to the period-over-period decline in revenue coupled with cost reduction efforts.

Gross profit. Gross profit was $7.3 million, or 67.1% of revenues, for the six months ended June 30, 2024, compared to $15.4 million, or 72.4% of revenues, for the six months ended June 30, 2023. The decrease of approximately $8.1 million in gross profit was driven by the period-over-period decline in revenue volume.

Selling and marketing. Selling and marketing expenses were $5.1 million and $6.2 million for the six months ended June 30, 2024 and 2023, respectively. This decrease of approximately $1.0 million was primarily due to decreases in personnel-related costs of $0.7 million coupled with a period-over-period decline in marketing costs of $0.6 million, partially offset by an increase in stock based compensation of approximately $0.3 million.

Research and development. Research and development expenses were $7.7 million and $9.6 million for the six months ended June 30, 2024 and 2023 respectively. This decrease of approximately $1.9 million was primarily due to a decline in

Table of Contents

personnel-related costs of approximately $1.3 million and reductions in contractor costs of $0.2 million coupled with a decline in severance related costs of approximately $0.4 million.

General and administrative. General and administrative expenses were $5.5 million and $6.5 million for the six months ended June 30, 2024 and 2023, respectively. This decrease of approximately $1.0 million was primarily related to declines in personnel-related costs of approximately $0.6 million, a decrease in professional fees of approximately $0.2 million and a reduction in occupancy costs of approximately $0.2 million.

Depreciation and amortization. Depreciation expense was $0.2 million and $0.4 million for the six months ended June 30, 2024 and 2023, respectively. Amortization expense was $3.3 million and $3.0 million for the six months ended June 30, 2024 and 2023, respectively. The decrease in depreciation expense of approximately $0.2 million was primarily due to certain fixed assets that have now been fully depreciated. Amortization expense is recognized based on the pattern of economic benefit expected to be generated from the use of the intangible assets, and as such it increased by approximately $0.3 million period-over-period.

Goodwill impairment. The impairment charge for the six months ended June 30, 2024 was triggered by the sustained decrease in our Common Stock share price and overall market capitalization during the first quarter of 2024, which led to an analysis whereby we concluded that the carrying value of our single reporting unit exceeded its fair value by $24.0 million.

Change in fair value of warrant and derivative liabilities. Change in fair value of warrant and derivative liabilities was $0.2 million for the six months ended June 30, 2024 and $3.4 million for the six months ended June 30, 2023, a decrease of $3.2 million. The fair value adjustments resulted from valuation related impacts to the warrant and derivative liabilities combined with the settlements of the Notes in the six months ended June 30, 2023. The Notes were retired at maturity in December 2023, and thus there were no changes in the fair value of the derivative liability in 2024.

Loss on derecognition of debt. The loss recognized on derecognition of debt was $1.4 million for the six months ended June 30, 2023. The $1.4 million loss recognized for the six months ended June 30, 2023 resulted from installment payments made on the Notes in the form of shares, and the required derecogition of the net debt position related to that principal balance, including the derivative and discounts. There was nothing commensurate in the six months ended June 30, 2024 as the convertible notes were retired at maturity as of December 31, 2023.

Interest income (expense), net. Interest income, net was $0.1 million for the six months ended June 30, 2024 and interest expense, net was $4.3 million for the six months ended June 30, 2023. The period-over-period change in interest income (expense), net of $4.4 million was primarily related to the amortization of the discount and debt issuance costs and stated interest expense related to the Notes, which were fully retired effective December 31, 2023.

Other (expense) income, net. Other income, net was $0.2 million for the six months ended June 30, 2024 and Other expense, net was $0.1 million for the six months ended June 30, 2023. The period-over-period change was primarily related to income derived from the licensing of several of our patents in February 2024.

Provision for income tax expense. Because of our cumulative loss position, the provision for income tax expense consists of state income taxes, foreign tax withholdings, and foreign income taxes for the six months ended June 30, 2024 and 2023. There were no material changes in the period-to-period comparison.

Liquidity and Capital Resources

The Company’s principal sources of liquidity are its existing cash and cash equivalents, and cash generated by operations.

As of June 30, 2024, the Company's cash and cash equivalents were approximately $5.6 million.

As more fully described in Note 4 of our Notes to the Consolidated Financial Statements included in this Report, in the second quarter of 2024, in order to fund working capital and for other general corporate purposes we received net proceeds of approximately $3.4 million through the issuance of additional Common Stock and Pre-Funded Warrants pursuant to a Registered Direct Offering and associated Private Placement. In addition to the Common Warrants issued in the Private Placement, we also have additional warrants outstanding, as further disclosed in Note 5 of our Notes to the Consolidated Financial Statements included in this Report.

Our liquidity may be adversely impacted by the anticipated effect of the aforementioned loss during 2023 of our Family Safety contract with a Tier 1 carrier on our results of operations, since we are receiving no revenue from that contract during 2024. While we have adjusted our cost structure and we anticipate marketing efforts to expand for one of our existing Tier 1 carrier customers in order to drive subscriber growth on our Family Safety product, and we expect to generate additional revenues from our recent launch with a carrier customer in the U.S. and our upcoming launch with a Tier 1 carrier in Europe, the timing of that anticipated revenue growth versus the immediate and current impact of the

Table of Contents

contract loss could cause the cash and cash equivalents on hand and expected to be generated in the next twelve months and beyond to be insufficient to fund operations at the current levels.

This potential adverse impact on liquidity does not trigger a violation of any covenants in our material agreements, particularly as all of our outstanding debt was retired as of December 31, 2023. The availability of sufficient funds will depend to an extent on the timing of subscriber growth and the related cash generation thereof, and/or the ability to obtain the necessary capital to meet our obligations and fund our working capital requirements to maintain normal business operations. To meet future cash needs, the Company may determine to take additional actions, as noted in the Risk Factor appearing in our 2023 Form 10-K under the heading, "If we are unable to meet our obligations as they become due over the next twelve months, the Company may not be able to continue as a going concern." There can be no assurance that any such potential actions will be available or will be available on satisfactory terms. Our ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, our performance and investor sentiment with respect to us and our industry. As a result of these uncertainties, and notwithstanding management's plans and efforts to date, we have been unable to alleviate substantial doubt about our ability to continue as a going concern within one year from the date that the financial statements are issued.

Cash Flows

Changes in cash and cash equivalents are as follows:


	For the Six Months Ended June 30,
(in thousands)	2024		2023

Net cash provided by investing activities	187		74
Net cash provided by (used in) financing activities	3,869		(192)
Net decrease in cash and cash equivalents	$	(1,497)	$	(7,609)

Operating activities

Net cash used in operating activities was $5.6 million for the six months ended June 30, 2024. The primary uses of operating cash were a net loss of $37.9 million less non-cash expenses totaling $29.3 million, primarily driven by a goodwill impairment charge of $24.0 million and stock compensation expense of $2.3 million, a decrease in accounts payable and accrued liabilities of $0.5 million and an increase in prepaid expenses and other assets of $0.2 million partially offset by a decrease in accounts receivable of $4.1 million.

Net cash used in operating activities was $7.5 million for the six months ended June 30, 2023. The primary uses of operating cash were the net loss of $12.6 million less non-cash expenses totaling $7.3 million, an increase in accounts receivable of $1.4 million and a decrease in accounts payable and accrued and other liabilities of $0.9 million.

Investing activities

Net cash provided by investing activities of $0.2 million for the six months ended June 30, 2024 was primarily attributable to the net proceeds from licensing several of our patents in February 2024. Net cash provided by investing activities for six months ended June 30, 2023 was $0.1 million.

Financing activities

Net cash provided by financing activities of $3.9 million for the six months ended June 30, 2024 was primarily attributable to the net cash proceeds of $3.4 million from the Registered Direct Offering and Private Placement and borrowings of $1.0 million less repayments of $0.5 million from short-term insurance premium financing arrangements.

Net cash used by financing activities was $0.2 million for the six months ended June 30, 2023.

Critical Accounting Estimates

Our discussion and analysis of results of operations, financial condition, and liquidity are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may materially differ from these estimates under different assumptions or conditions. On an ongoing basis, we review our estimates to ensure that they appropriately reflect changes in our business or new information as it becomes available. See Note 1 of our Notes to the Consolidated Financial Statements in our 2023 Form 10-K for information regarding our critical accounting estimates. There have been no material changes to the Company's critical accounting estimates since the 2023 Form 10-K.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures

We conducted an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (“Exchange Act”)) as of June 30, 2024. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have determined that as of June 30, 2024, our disclosure controls and procedures were effective to ensure that the information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and our management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Management’s responsibility for financial statements

Our management is responsible for the integrity and objectivity of all information presented in this Report. The consolidated financial statements were prepared in conformity with U.S. GAAP and include amounts based on management’s best estimates and judgments. Management believes the consolidated financial statements fairly reflect the form and substance of transactions and that the financial statements fairly represent the Company’s financial position and results of operations for the periods and as of the dates stated therein.

The Audit Committee of the Company’s Board of Directors, which is composed solely of independent directors, meets regularly with our independent registered public accounting firm, SingerLewak LLP, and representatives of management to review accounting, financial reporting, internal control, and audit matters, as well as the nature and extent of the audit effort. The Audit Committee is responsible for the engagement of the independent auditors. The independent auditors have free access to the Audit Committee.

Changes in internal control over financial reporting

There have been no changes in our internal control over financial reporting during the quarter ended June 30, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company Smith Micro Software, Inc. (“Smith Micro” or “the Company”) provides software solutions that simplify and enhance the mobile experience to some of the leading wireless service providers around the globe. From delivering Digital Familly LifestyleTM solutions to providing powerful voice messaging capabilities, the Company strives to enrich today’s connected lifestyles while creating new opportunities to engage consumers via smartphones and consumer Internet of Things (“IoT”) devices. Smith Micro’s portfolio includes family safety software solutions to support families in the digital age and a wide range of products for creating, sharing, and monetizing rich content, such as visual voice messaging, retail content display optimization and performance analytics on any product set. Smith Micro’s solution portfolio is comprised of proven products that enable its customers to provide: •In-demand digital services that connect today’s digital lifestyle, including family location services, parental controls, and consumer IoT devices to mobile consumers worldwide; •Easy visual access to voice messages on mobile devices through visual voicemail and voice-to-text transcription functionality; and •Strategic, consistent, and measurable digital demonstration experiences that educate retail shoppers, create awareness of products and services, drive in-store sales, and optimize retail experiences with actionable analytics derived from in-store customer behavior. On April 3, 2024, the Company filed a certificate of amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to effect a one-for-eight (1:8) reverse stock split of the shares of the Company's common stock, par value $0.001 per share (the "Common Stock"), with an effective time of 11:59 p.m., Eastern Time on April 10, 2024 (the "Reverse Stock Split"). At the effective time, every eight shares of Common Stock, whether issued and outstanding or held by the Company as treasury stock were automatically combined and converted (without any further act) into one share of fully paid and nonassessable Common Stock, with any fractional shares resulting from the Reverse Stock Split rounded up to the nearest whole share. The number of outstanding shares of Common Stock was reduced from approximately 76.8 million shares to approximately 9.6 million shares due to the Reverse Stock Split. The Reverse Stock Split did not change the Company's authorized shares of Common Stock from 100,000,000 shares or the par value of the Common Stock. Proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise of stock options and the settlement of restricted stock awards and the number of shares authorized and reserved for issuance pursuant to the Company's equity incentive plans (see Note 9). Additionally, there were adjustments to the per share exercise price and the number of shares issuable upon exercise of warrants (see Note 5). All share and per share amounts for Common Stock (including share amounts underlying convertible securities and the applicable exercise prices of such convertible securities) in these consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split, including reclassifying an amount equal to the reduction in the number of shares of Common Stock at par value to additional paid-in capital.

Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation The accompanying interim consolidated balance sheet as of June 30, 2024, and the related consolidated statements of operations and stockholders’ equity for the three and six months ended June 30, 2024 and 2023, and the consolidated statements of cash flows for the six months ended June 30, 2024 and 2023, are unaudited. The unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been omitted. In the opinion of management, the accompanying unaudited consolidated financial statements for the periods presented reflect all adjustments which are normal and recurring, and necessary to fairly state the financial position, results of operations, and cash flows of the Company. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 26, 2024 (the "2023 Form 10-K"). Intercompany balances and transactions have been eliminated in consolidation. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2024. New Accounting Pronouncements In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Improvements to Reportable Segment Disclosures." This update was issued to improve and enhance reportable segment disclosure requirements. The amendments in this update require annual and interim disclosures on significant segment expenses that are regularly provided to the chief operating decision maker and require annual and interim disclosures on “other segment items” that comprise the difference between segment revenue less segment expense compared to the reported measure of segment profit or loss. In addition, the amendments will require all annual disclosures that are currently required to be reported on an interim basis and requires disclosure of the title and position of the chief operating decision maker and how that position uses the information to assess segment performance and the allocation of resources. ASU 2023-07 also requires entities that have a single reportable segment, such as the Company, to provide all disclosures required in this update and the existing segment disclosures in Topic 280. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of ASU 2023-07 and does not expect them to have a material effect on the consolidated financial statements. In December 2023, FASB issued ASU 2023-09, "Income Tax Disclosures." ASU 2023-09 was issued to require annual disclosures on specific categories in the income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold.

Going Concern	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Going Concern	Going Concern The Company's financial statements have been presented on the basis that it is a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. In connection with preparing interim consolidated financial statements for the three and six months ended June 30, 2024, certain conditions in the Company's evaluation, considered in the aggregate, have raised substantial doubt about the Company's ability to continue as a going concern within one year from the date that the financial statements are issued, which has not been alleviated. The evaluation considered the Company's financial condition, including its liquidity sources, funds necessary to maintain the Company's operations considering the current financial condition, obligations, and other expected cash flows, and negative financial trends of recurring operating losses and negative cash flows. The Company has no outstanding debt and is continuing operations and generating revenues in the normal course of business, however the Company is dependent, to an extent, on the timing of subscriber and revenue growth for its products and the related cash generation from that growth and/or the ability to obtain the necessary capital to meet its obligations and fund its working capital requirements to maintain normal business operations. Management believes that the actions presently being taken to implement the Company's business plan to expand subscriber growth, including dynamic marketing campaigns, to acquire new customers and to expand its offerings to existing customers to generate increased revenues, and, if necessary, to raise additional capital will support the Company's operations; as such the financial statements do not include any adjustments that may be necessary if the Company is unable to continue as a going concern. The Company believes that it would be able to raise additional funds as necessary, through public or private equity offerings, including via accessing its currently effective shelf registration or by filing one or more additional registration statements, debt financings, or a combination of these funding sources as evidenced by the Company historically being able to complete debt and equity financings. However it may not be able to secure such incremental capital in a timely manner or on favorable terms, if at all. In order to preserve liquidity, the Company may also take one or more of the following additional actions: •Implement additional restructuring and cost reductions, •Secure a revolving line of credit, if available, •Dispose of one or more product lines and/or, •Sell or license intellectual property. While management believes that the Company’s plans for growing revenue and the other potential actions available to it would alleviate the conditions that raise substantial doubt, these strategies are not entirely within the Company’s control and cannot be assessed as being probable of occurring.

Common Stock	Jun. 30, 2024
Equity [Abstract]
Common Stock	Common Stock Minimum Bid Price Requirement and Reverse Stock Split On December 27, 2023, the Company received a notice (the "Notice") from the Nasdaq Stock Market ("Nasdaq") that the Company was not in compliance with the $1.00 minimum bid price requirement for continued listing, as set forth in Nasdaq Listing Rule 5550(a)(2) (the "Minimum Bid Price Requirement"), as the closing bid price of the Company’s Common Stock had been below $1.00 per share for more than thirty (30) consecutive business days as of the date of the Notice. As previously noted, the Company undertook the Reverse Stock Split, which became effective April 10, 2024 at 11:59 pm Eastern time, to enable the Company to regain compliance with the Minimum Bid Price Requirement. On April 29, 2024, the Company received notice from Nasdaq that it had regained compliance with the Minimum Bid Price Requirement, and the matter is now closed. May 2024 Registered Direct Offering & Private Placement On May 10, 2024, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with certain institutional and accredited investors (the “Purchasers”) relating to the registered direct offering and sale of an aggregate of 1,065,000 shares of the Company’s Common Stock at an offering price of $2.15 per share of Common Stock and pre-funded warrants (“Pre-Funded Warrants”) to purchase up to 845,000 shares of Common Stock (the “Registered Direct Offering”). The Pre-Funded Warrants were purchased at a price of $2.149 per underlying share and have an exercise price of $0.001 per share and can be exercised at any time after their original issuance until such Pre-Funded Warrants are exercised in full. The shares of Common Stock and Pre-Funded Warrants (including the shares of Common Stock underlying the warrants) were offered by the Company pursuant to a prospectus supplement dated May 10, 2024, and accompanying prospectus dated May 12, 2022, in connection with a takedown from the Company’s shelf registration statement on Form S-3 (File No. 333-264667), which was declared effective by the SEC on May 12, 2022. In a private placement on May 14, 2024, concurrent with the Registered Direct Offering, the Company also sold to the Purchasers unregistered warrants (the “Common Warrants”) to purchase up to an aggregate of 1,910,000 shares of Common Stock (the “Private Placement”). Each unregistered Common Warrant has an exercise price of $2.34 per share, is exercisable at any time beginning November 14, 2024 and will expire November 14, 2029. Both the Registered Direct Offering and the Private Placement closed on May 14, 2024. Roth Capital Partners, LLC (“Roth”) acted as the exclusive placement agent for the Registered Direct Offering and the Private Placement pursuant to a placement agency agreement (the “Placement Agency Agreement”) dated May 10, 2024, by and between the Company and Roth, and a related engagement letter with Roth. Pursuant to the Placement Agency Agreement, on May 14, 2024 the Company issued to Roth warrants to purchase up to 133,700 shares of Common Stock (the “Placement Agent Warrants”), which represented 7.0% of the aggregate number of shares of Common Stock and Pre-Funded Warrants sold in the Registered Direct Offering. The Placement Agent Warrants are exercisable at any time beginning November 14, 2024, have an exercise price equal to $2.86, and expire November 16, 2026. The shares of Common Stock underlying the Common Warrants and the Placement Agent Warrants (collectively referred to herein as the “Warrants”) were registered on a registration statement on Form S-1 (File No. 333-280542) filed with the SEC on June 27, 2024, which was declared effective by the SEC on July 10, 2024. Shares of Common Stock issued by the Company upon exercise of the Warrants may be resold by the holders pursuant to the prospectus dated July 11, 2024. The filings made by the Company in connection with the potential resale of the Common Stock underlying the Warrants were filed within the time period agreed by the parties in the Purchase Agreement. The net cash proceeds to the Company, after deducting offering related expenses was $3.4 million. The Pre-Funded Warrants, Common Warrants, and Placement Agent Warrants were all assessed and recorded as equity instruments. During the three and six months ended June 30, 2024, no Pre-Funded Warrants, Common Warrants or Placement Agent Warrants from the Registered Direct Offering and Private Placement were exercised. The 845,000 shares of the Company's Common Stock underlying the above described Pre-Funded Warrants are not included in the number of issued and outstanding shares of the Company's Common Stock outstanding as reported on the consolidated balance sheet, though they are included in the Company's weighted average outstanding Common Stock in the calculation of basic and diluted net loss per share, as further disclosed in Note 8.

Commitments and Contingencies	Commitments and Contingencies Litigation The Company may become involved in various legal proceedings arising from its business activities. While management does not believe the ultimate disposition of these matters will have a material adverse impact on the Company’s consolidated results of operations, cash flows, or financial position, litigation is inherently unpredictable, and depending on the nature and timing of these proceedings, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows, or financial position in a particular period. Other Contingent Contractual Obligations During its normal course of business, the Company has made certain indemnities, commitments, and guarantees under which it may be required to make payments in connection with certain transactions. These include: indemnities to the Company’s customers pursuant to contracts for the Company’s products and services, including indemnities with respect to intellectual property, confidentiality and data privacy; indemnities to various lessors in connection with facility leases for certain claims arising from use of such facility or under such lease; indemnities to vendors and service providers pertaining to claims based on the negligence or willful misconduct of the Company; indemnities involving the accuracy of representations and warranties in certain contracts; and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware. In addition, the Company has made or may make contractual commitments to employees providing for severance payments upon the occurrence of certain prescribed events. The Company may also issue a guarantee in the form of a standby letter of credit as security for contingent liabilities under certain customer contracts. The duration of these indemnities, commitments, and guarantees varies, and in certain cases may be indefinite. The majority of these indemnities, commitments, and guarantees may not provide for any limitation of the maximum potential for future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities, commitments, and guarantees in the accompanying consolidated balance sheets.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company accounts for income taxes as required by FASB ASC Topic No. 740, Income Taxes. The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax liabilities against gross deferred tax assets); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies; and (4) future taxable income exclusive of reversing temporary differences and carryforwards. In assessing whether a valuation allowance is required, significant weight is given to evidence that can be objectively verified. Realization of deferred tax assets is dependent upon the generation of future taxable income. As required by ASC 740, Smith Micro has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets and determined that it was more likely than not that the Company would not realize the deferred tax assets due to the Company's cumulative losses and uncertain near-term market and economic conditions, which reduce the Company’s ability to rely on projections of future taxable income in assessing the realizability of its deferred tax assets. After a review of the four sources of taxable income as of June 30, 2024, and after consideration of the Company’s cumulative loss position as of December 31, 2023, the Company will continue to reserve its U.S.-based deferred tax amounts, which total $58.5 million as of June 30, 2024. The Company is subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. The Company is no longer subject to examination for U.S. federal income tax returns for years before December 31, 2019 and for state income tax returns, the Company is no longer subject to examination for years before December 31, 2018. As of June 30, 2024, the Company had no outstanding tax audits. The outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs. Smith Micro may from time to time be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to the consolidated financial results of the Company. It is the Company’s policy to classify any interest and/or penalties in the consolidated financial statements as a component of income tax expense.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying interim consolidated balance sheet as of June 30, 2024, and the related consolidated statements of operations and stockholders’ equity for the three and six months ended June 30, 2024 and 2023, and the consolidated statements of cash flows for the six months ended June 30, 2024 and 2023, are unaudited. The unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been omitted. In the opinion of management, the accompanying unaudited consolidated financial statements for the periods presented reflect all adjustments which are normal and recurring, and necessary to fairly state the financial position, results of operations, and cash flows of the Company. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 26, 2024 (the "2023 Form 10-K"). Intercompany balances and transactions have been eliminated in consolidation. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2024.
New Accounting Pronouncements	In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Improvements to Reportable Segment Disclosures." This update was issued to improve and enhance reportable segment disclosure requirements. The amendments in this update require annual and interim disclosures on significant segment expenses that are regularly provided to the chief operating decision maker and require annual and interim disclosures on “other segment items” that comprise the difference between segment revenue less segment expense compared to the reported measure of segment profit or loss. In addition, the amendments will require all annual disclosures that are currently required to be reported on an interim basis and requires disclosure of the title and position of the chief operating decision maker and how that position uses the information to assess segment performance and the allocation of resources. ASU 2023-07 also requires entities that have a single reportable segment, such as the Company, to provide all disclosures required in this update and the existing segment disclosures in Topic 280. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of ASU 2023-07 and does not expect them to have a material effect on the consolidated financial statements. In December 2023, FASB issued ASU 2023-09, "Income Tax Disclosures." ASU 2023-09 was issued to require annual disclosures on specific categories in the income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. Annual disclosures are required on income taxes paid, including the amounts paid for federal, state and foreign taxes and the amount paid in individual jurisdictions if the amount is equal to or greater than 5% of total income taxes paid (net of refunds received). Additional annual disclosures are required on pre-tax income from continuing operations and income tax expense, disaggregated by domestic and foreign amounts. The amendments in this update are effective for fiscal years beginning after December 15, 2024. The Company is evaluating the accounting and disclosure requirements of ASU 2023-09 and does not expect them to have a material effect on the consolidated financial statements.
Reclassifications	Certain reclassifications have been made to the prior year financial statements to conform to the current presentation.
Fair Value of Financial Instruments	The Company measures and discloses fair value measurements as required by FASB ASC Topic No. 820, Fair Value Measurements and Disclosures. Fair value is an exit price, representing the amount that would be received upon the sale of an asset or the amount that would be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the FASB establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: •Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. •Level 2 – Include other inputs that are directly or indirectly observable in the marketplace. •Level 3 – Unobservable inputs which are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
Earnings Per Share	The Company calculates earnings per share (“EPS”) as required by FASB ASC Topic No. 260, Earnings Per Share. Basic EPS is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, excluding common stock equivalents. Diluted EPS is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding for the period, plus the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. The 845,000 shares of the Company's Common Stock issuable upon exercise of the Pre-Funded Warrants, described in Note 4 to these consolidated financial statements, are included in the weighted average outstanding Common Stock in the calculation of basic and diluted net loss per share as the exercise price is non-substantive at $0.001 per share. For periods with a net loss, the dilutive common stock equivalents are excluded from the diluted EPS calculation. For purposes of this calculation, Common Stock subject to repurchase by the Company, options, warrants (other than the Pre-Funded Warrants), and convertible notes are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive.
Segment Information	Public companies are required to report financial and descriptive information about their reportable operating segments as required by FASB ASC Topic No. 280, Segment Reporting. The Company has one primary business unit based on how management internally evaluates separate financial information, business activities and management responsibility: Wireless. The Wireless segment includes the Family Safety (which includes SafePath®), CommSuite®, and ViewSpot® families of products. The Company does not separately allocate operating expenses to these product lines, nor does it allocate specific assets. Therefore, product line information reported includes only revenues.
Income Taxes	The Company accounts for income taxes as required by FASB ASC Topic No. 740, Income Taxes. The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax liabilities against gross deferred tax assets); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies; and (4) future taxable income exclusive of reversing temporary differences and carryforwards. In assessing whether a valuation allowance is required, significant weight is given to evidence that can be objectively verified. Realization of deferred tax assets is dependent upon the generation of future taxable income. As required by ASC 740, Smith Micro has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets and determined that it was more likely than not that the Company would not realize the deferred tax assets due to the Company's cumulative losses and uncertain near-term market and economic conditions, which reduce the Company’s ability to rely on projections of future taxable income in assessing the realizability of its deferred tax assets.
