How to Vote Your Shares

If you are a stockholder of record, you may cause your shares to be voted by using one of the following methods:

Please carefully review the table below.

If you hold your shares in street name, you will receive instructions from the broker, bank or other nominee that holds your shares as to how to vote your shares at the special meeting. If you hold your shares in street name, you may not vote your shares in person at the special meeting unless you obtain a “legal proxy” from the broker, bank or other nominee that holds your shares, giving you the right to vote the shares at the special meeting.

If you are a stockholder of record, you may change or revoke a previously submitted proxy at any time before it is exercised by one of the following methods:

The Transaction (Page 22)

The Subscription Agreement provides that, subject to the satisfaction or waiver of the conditions set forth therein, AJP Holding will acquire the Purchased Shares. Holders of common stock of the Company will not receive any proceeds in the transaction.

Our common stock is listed on Nasdaq, and, as such, we are subject to the Nasdaq Listing Rules, including Nasdaq Listing Rule 5635. In order to comply with the Nasdaq Listing Rules and to satisfy conditions under the Subscription Agreement, we are seeking stockholder approval of this Proposal 1. Nasdaq Listing Rule 5635(b) requires stockholder approval for issuance of securities that will result in a “change of control” of the issuer. Nasdaq may deem a change of control to occur when, as a result of an issuance, an investor or a group would own, or have the right to acquire, 20% or more of the outstanding shares of common stock or voting power and such ownership or voting power of an issuer would be the largest ownership position of the issuer. The Board is not seeking the approval of our stockholders to authorize our entry into the Subscription Agreement. The Subscription Agreement has already been executed and delivered. We seek your approval of this proposal in order to satisfy the requirements of Nasdaq Listing Rule 5635 with respect to the issuance of the common stock to the Purchaser in a “change of control” transaction.

Transaction Consideration (Page 22)

In the transaction, AJP Holding will acquire each share of our common stock for $0.84 for an aggregate purchase price of $17,500,000 (which we refer to as the “Aggregate Consideration”).

Reasons for the Transaction; Recommendation of the Board (Page 38)

After careful consideration of various factors as described in the section entitled “The Transaction—Reasons for the Transaction; Recommendation of the Board” beginning on page 38, the Board unanimously determined that the Subscription Agreement and the transactions contemplated thereby are fair to and in the best interests of the Company’s stockholders, and adopted and declared advisable the Subscription Agreement and the transactions contemplated thereby. The Board unanimously resolved, subject to certain provisions of the Subscription Agreement, to recommend that the Company’s stockholders adopt the Subscription Agreement (which we refer to as the “Board recommendation”), all upon the terms and subject to the conditions set forth therein. The Board consulted with the Company’s outside financial and legal advisors and senior management and considered a number of factors that the Board believes support its decision.

In considering the recommendation of the Board with respect to the Transaction Proposal, you should be aware that our directors and executive officers may have interests in the transaction that may be different from, or in addition to, yours. The Board was aware of and considered these interests, among other matters, in evaluating and negotiating the transaction agreement, and in recommending that the transaction agreement be adopted by the stockholders of the Company. See “The Transaction—Interests of Certain Persons in the Transaction” beginning on page 51.

The Board has unanimously determined that the Subscription Agreement and the transactions contemplated thereby are fair to and in the best interests of the Company’s stockholders, adopted and declared advisable the Subscription Agreement and the transactions contemplated thereby and recommends that you vote “FOR” approval of the Transaction Proposal.

Opinion of B. Riley Securities, Inc. (Page 45)

The Company engaged B. Riley Securities, Inc. (which we refer to as “B. Riley”) to provide financial advice in connection with the proposed transaction based on B. Riley’s qualifications, expertise, reputation and knowledge of the Company’s business and the industry in which the Company operates. At the meeting of the Board on

April 13, 2022, B. Riley delivered to the Board its oral opinion, subsequently confirmed in writing, to the effect that, as of April 13, 2022 and based upon and subject to the various assumptions, qualifications, limitations and other matters set forth therein, the transaction consideration to be received by the holders of shares of common stock pursuant to, and in accordance with, the terms of the Subscription Agreement was fair, from a financial point of view, to such holders.

The full text of the opinion of B. Riley, dated as of April 13, 2022, is attached to this proxy statement as Annex B and is incorporated into this proxy statement by reference. The opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations and qualifications of the review undertaken by B. Riley in rendering its opinion. You should read the opinion carefully in its entirety.

B. Riley’s opinion was provided to the Board and addressed only, as of the date of the opinion, the fairness, from a financial point of view, of the transaction consideration to be received by the holders of shares of common stock pursuant to, and in accordance with, the terms of the Subscription Agreement to such holders. It does not address any other aspect of the transaction. It does not constitute a recommendation to any Company stockholder as to how to vote with respect to the transaction or any other matter and does not in any manner address the prices at which the shares of common stock will trade at any time.

Financing of the Transaction (Page 50)

AJP Holding expects to fund amounts needed to acquire the Company under the Subscription Agreement through cash on hand at the closings. The Company and AJP Holding’s obligations under the Subscription Agreement are not subject to, or conditioned on, the receipt or availability of any funds or financing.

Interests of Certain Persons in the Transaction (Page 51)

In considering the recommendation of the Board that you vote to approve the Transaction Proposal, you should be aware that the Company’s directors and executive officers may have interests in the transaction that may be different from, in conflict with or in addition to, those of the Company stockholders generally. Members of the Board were aware of and considered these interests, at the time, among other matters, in evaluating and negotiating the Subscription Agreement and the transaction, approving the Subscription Agreement and in recommending to the Company stockholders that the Subscription Agreement be adopted. For more information, see the section entitled “The Transaction—Interests of Certain Persons in the Transaction” beginning on page 51.

Material U.S. Federal Income Tax Consequences of the Transaction

The following discussion is a summary of U.S. federal income tax considerations relating to the issuance of Company common stock pursuant to the transaction. This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, administrative pronouncements and judicial decisions, all in effect as of the date of this Proxy Statement and all subject to change, possibly with retroactive effect. This summary does not address consequences of the transaction under state, local and foreign tax laws.

For U.S. federal income tax purposes, the issuance of Company common stock will not result in taxable income or gain for the Company, for its subsidiaries or for stockholders that own common stock of the Company prior to the transaction.

As a result of the issuance of Company common stock, the Company and its U.S. subsidiaries (collectively, the “U.S. Subsidiaries”) will undergo an “ownership change” within the meaning of Sections 382 and 383 of the Code. In general terms, an “ownership change” with respect to a corporation occurs if the stock ownership in the corporation of one or more five-percent or greater shareholders increases by more than fifty (50) percentage points over a period of three (3) years or less. Sections 382 and 383 of the Code impose limitations on a corporation’s ability to utilize its net operating loss carryforwards (“U.S. NOLs”), capital loss carryovers and tax credits if the corporation (a “Loss Corporation”) experiences an “ownership change.” Generally the amount of otherwise available pre-ownership-change NOLs and other affected tax attributes of a Loss Corporation that can be used by the Loss Corporation in any single post-ownership-change tax year is limited to the fair market value of the Loss Corporation at the time of the ownership change, multiplied by the applicable long-term tax-exempt bond rate (which is 2.01% for ownership changes in May 2022). As of December 31, 2021, the Company and its U.S. Subsidiaries had approximately $89,245,000 of U.S. NOLs, $0 U.S. capital loss carryovers and $132,000 of U.S. federal tax credit carryovers. For U.S. tax years ending after the issuance of Company common stock pursuant to the transaction, the annual use of those favorable pre-ownership-change tax attributes will be limited as described above and may result in a portion of the U.S. NOLs and other tax attributes expiring unutilized.

Regulatory Approvals

The Company and AJP Holding have agreed to cooperate and coordinate with each other and, subject to the terms and conditions of the Subscription Agreement, use their respective reasonable best efforts to, among other matters, obtain and maintain all approvals, consents, registrations, permits, authorizations, licenses, waivers and other confirmations required to be obtained from any governmental entity or applicable law that are necessary to consummate the transactions contemplated by the Subscription Agreement.

Under the terms of the Subscription Agreement, subject to certain exceptions, the Company has agreed not to, directly or indirectly (i) solicit, initiate or knowingly facilitate or encourage the submission of any inquiry, proposal or offer that constitutes, or would reasonably be expected to result in, an acquisition proposal (as defined in the section entitled “The Subscription Agreement—No Solicitation of Acquisition Proposals; Board Recommendation Changes” beginning on page 58), (ii) enter into, continue or participate in any discussions or negotiations with, or furnish any non-public information relating to the Company or any of its subsidiaries to, any third party in connection with an acquisition proposal, (iii) approve, recommend, publicly declare advisable or enter into any agreement in principle, letter of intent, subscription agreement, acquisition agreement, joint venture agreement or other similar agreement relating to an acquisition proposal (other than a confidentiality agreement entered into in accordance with the provisions of the Subscription Agreement (we refer to such a confidentiality agreement as an “acceptable confidentiality agreement”)), or (iv) agree to or propose publicly to do any of the foregoing.

Notwithstanding these restrictions, at any time prior to the time the Subscription Agreement is adopted by our stockholders, subject to the terms and conditions described in the Subscription Agreement, the Company may engage in negotiations or discussions with a third party and its representatives and actual or potential sources of financing and furnish to such persons non-public information relating to the Company or any of its subsidiaries pursuant to an acceptable confidentiality agreement so long as such actions are in response to a written acquisition proposal from any third party that did not result from a breach of the non-solicitation obligations of the Company contained in the Subscription Agreement and that the Board determines in good faith: (i) to be bona fide, (ii) after consultation with its financial advisor and outside legal counsel, constitutes, or would reasonably be expected to result in, a superior proposal (as defined in the section entitled “The Subscription Agreement—No Solicitation of Acquisition Proposals; Board Recommendation Changes” beginning on page 58) or (iii) after consultation with its outside legal counsel, that the failure to take such action would reasonably be expected to result in a breach of the fiduciary duties of the Company’s directors under applicable law.

The Company must notify Purchaser both orally and in writing promptly (but in no event later than twenty-four (24) hours) after receipt of any acquisition proposal, any proposals or inquiries that would reasonably be expected to lead to an acquisition proposal, or any inquiry or request for nonpublic information relating to the Company or its subsidiaries by any person who had made or has expressly indicated that it is contemplating making any acquisition proposal.

The Subscription Agreement may also be terminated and the transaction abandoned at any time prior to the closing of the transaction, as follows:

Termination Fee & Reimbursement Obligation (Page 66)

In certain circumstances, the Company may be required to pay AJP Holding a termination fee of $750,000 (which we refer to as the “termination fee”) if the Subscription Agreement is terminated, as well as reimburse AJP Holding for certain reasonable, documented out-of-pocket expenses up to $350,000 (which we refer to as the “reimbursement obligation”).

The termination fee and reimbursement obligation would be payable in the following circumstances:

The reimbursement obligation would be payable in the following circumstances:

Specific Performance (Page 68)

The Company and AJP Holding have agreed that irreparable damage for which monetary damages, even if available, would not be an adequate remedy that would occur in the event that the parties do not perform their obligations under the Subscription Agreement in accordance with its specified terms or otherwise breach such provisions. The Company and AJP Holding have further agreed that each party is entitled to an injunction or injunctions, specific performance or other equitable relief to prevent breaches of the Subscription Agreement and to enforce specifically the terms and provisions of the Subscription Agreement without proof of damages.

Market Price of Common Stock (Page 80)

The Company’s common stock is listed on Nasdaq under the symbol “SONM.” The closing price of our common stock on Nasdaq on April 12, 2022, the last trading day prior to the public announcement of the execution of the Subscription Agreement, was $0.66 per share. On May 20, 2022, the most recent practicable date before this proxy statement was mailed to our stockholders, the closing price for our common stock on Nasdaq was $0.51 per share. You are encouraged to obtain current market quotations for our common stock in connection with voting your shares of common stock.

Voting by Proxy

Q. What is the deadline for voting?

If you hold your shares in street name, please comply with the deadlines for voting provided by the broker, bank or other nominee that holds your shares.

Written notices of revocation should be addressed to:

6500 River Place Blvd.

Building 7, Suite 250

Austin, TX 78746

Attention: Robert Tirva, Secretary

Any change to your proxy that is provided by telephone or the Internet must be submitted by 11:59 p.m., Pacific Time, on June 27, 2022, the day before the special meeting.

If your shares are held in “street name,” you must contact your broker, bank or other nominee to find out how to change or revoke your voting instructions.

In accordance with applicable stock exchange rules, if you hold your shares through a brokerage account and you fail to provide voting instructions to your broker, your broker may generally vote your uninstructed shares of common stock in its discretion on routine matters at a stockholder meeting. However, a broker cannot vote shares of common stock held in street name on non-routine matters unless the broker receives voting instructions from the stockholder. Generally, if a broker exercises this discretion on routine matters at a stockholder meeting, a stockholder’s shares will be voted on the routine matter in the manner directed by the broker but will constitute a “broker non-vote” on all of the non-routine matters to be presented at the stockholder meeting. The Transaction Proposal and the Charter Restriction Proposal are non-routine matters. Accordingly, if you hold your shares in street name through a brokerage account, your broker will not be able to exercise its discretion to vote uninstructed shares on those proposals presented at the special meeting. The Reverse Stock Split Proposal and the Adjournment Proposal are routine matters. Accordingly, if you hold your shares in street name through a brokerage account, your broker will be able to exercise its discretion to vote uninstructed shares on those proposals presented at the special meeting.

For the Reverse Stock Split Proposal, you may vote “FOR,” “AGAINST,” or “ABSTAIN.” Abstentions will have the same effect as a vote “AGAINST” the Reverse Stock Split Proposal. In addition, if you do not submit a valid proxy or attend the special meeting to vote your shares of common stock in person or if you hold your shares of common stock in street name and fail to instruct your broker, bank or other nominee how to vote your shares on the Reverse Stock Split Proposal, your broker will be able to exercise its discretion to vote uninstructed shares on the Reverse Stock Split Proposal.

For the Charter Restriction Proposal, you may vote “FOR,” “AGAINST,” or “ABSTAIN.” Abstentions will have the same effect as a vote “AGAINST” the Charter Restriction Proposal. In addition, if you do not

submit a valid proxy or attend the special meeting to vote your shares of common stock in person or if you hold your shares of common stock in street name and fail to instruct your broker, bank or other nominee how to vote your shares on the Charter Restriction Proposal, it will have the same effect as a vote “AGAINST” the Charter Restriction Proposal.

For the Adjournment Proposal, you may vote “FOR,” “AGAINST,” or “ABSTAIN.” Abstentions will have no impact on the outcome of the vote on the Adjournment Proposal. In addition, if you do not submit a valid proxy or attend the special meeting to vote your shares of common stock in person or if you hold your shares of common stock in street name and fail to instruct your broker, bank or other nominee how to vote your shares on the Adjournment Proposal, your broker will be able to exercise its discretion to vote uninstructed shares on the Adjournment Proposal.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This proxy statement contains forward-looking statements within the meaning of Section 27Aannual meeting, in person or represented by proxy, of the Securities Actholders of 1933, as amended (which we refer to as the “Securities Act”), and Section 21Eone-third of the Exchange Act, which statements involve substantial risks and uncertainties. All statements, other than statements of historical or current facts included in this proxy statement, are forward-looking statements. These statements are often identified by the words “believe,” “expect,” “may,” “anticipate,” “intend,” “estimate,” “project,” “plan,” “assume,” “seek to” or other similar expressions, whether in the negative or the affirmative, that are not statements of historical fact.

These forward-looking statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict and many of which we have no control over. You should not place undue reliance on our forward-looking statements. These factors, risks and uncertainties include, but are not limited to, the following: (i) the possibility that the Company may be unable to obtain the required stockholder approval or that other conditions to closing the transaction may not be satisfied, such that the transaction will not close or that the closing may be delayed; (ii) the reaction of customers to the transaction; (iii) general economic conditions; (iv) the amount of the costs, fees, expenses and charges related to the transaction; (v) the outcome of any legal proceedings related to the transaction, if any; (vi) the occurrence of any event, change or other circumstances that could give rise to the termination of the Subscription Agreement; and (vii) other factors discussed from time to time in our reports filed with the SEC, including the factors discussed in Item 1A, “Risk Factors” of the Company’s 2021 Annual Report on Form 10-K filed with the SEC on March 21, 2022 and subsequent filings the Company makes with the SEC, which are available at www.sec.gov.

You should not rely upon forward-looking statements as predictions of future events.

PROPOSAL 1: APPROVAL OF THE ISSUANCE OF COMMON STOCK CONTEMPLATED

BY THE SUBSCRIPTION AGREEMENT

THE TRANSACTION

This discussion of the transaction is qualified in its entirety by reference to the Subscription Agreement, which is attached to this proxy statement as Annex A. You should read the entire Subscription Agreement carefully and in its entirety, as it is the legal document that governs the transaction.

The Subscription Agreement provides that, subject to the satisfaction or waiver of the conditions set forth in the Subscription Agreement, AJP Holding will acquireCompany, LLC, following the Purchased Shares for the Aggregate Consideration. As a result of the transaction, AJP Holding will own approximately 52% of the Company. Holders of common stock of the Company will not receive any consideration from the transaction.

Our common stock is listed on Nasdaq, and, as such, we are subject to the Nasdaq Listing Rules, including Nasdaq Listing Rule 5635. In order to comply with the Nasdaq Listing Rules and to satisfy conditions under the Subscription Agreement, we are seeking stockholder approval of this Proposal 1. NASDAQ Listing Rule 5635(b) requires stockholder approval for issuance of securities that will result in a “change of control” of the issuer. Nasdaq may deem a change of control to occur when, as a result of an issuance, an investor or a group would own, or have the right to acquire, 20% or more of the outstanding shares of common stock or voting power and such ownership or voting power of an issuer would be the largest ownership position of the issuer. The Board is not seeking the approval of our stockholders to authorize our entry into the Subscription Agreement. The Subscription Agreement has already been executed and delivered. We seek your approval of this proposal in order to satisfy the requirements of Nasdaq Listing Rule 5635 with respect to the issuance of the common stock to the Purchaser in a “change of control” transaction.

Transaction Consideration

In the transaction, each share of common stock is being sold for $0.84. Holders of common stock of the Company will not receive any consideration from the transaction.

Description of the Common Stock

The shares of our common stock to be issued to Purchaser, if any, will be unregistered and the same class of common stock that we have listed on Nasdaq under the trading symbol “SONM.” Holders of our common stock have no preemptive rights.

Background of the Transaction

On a regular basis, the Board, together with Sonim’s management team, which we refer to as “management”, has reviewed and assessed Sonim’s performance, future growth prospects, net losses (including, as a result thereof, substantial doubt about Sonim’s ability to continue as a going concern during 2022), business strategies, opportunities and competitive position and challenges as part of its evaluation of Sonim’s prospects and strategies for enhancing stockholder value. As part of that review process, including as a result of Sonim’s current financial position and substantial doubt about Sonim’s ability to continue as a going concern during 2022, the Board and management have regularly reviewed and considered Sonim’s strategic direction and business objectives, including strategic opportunities that might be available to Sonim, such as possible acquisitions, investments, divestitures and business combination transactions.

Certain of these potential transaction parties executed a confidentiality agreement with Sonim, participated in management meetings with Sonim management, and were provided electronic data room access. All of the confidentiality agreements or non-disclosure agreements entered into by Sonim in this process either contained a standstill provision that automatically terminated upon Sonim’s entry into the Subscription Agreement or did not contain a standstill provision. Prior to the engagement of B. Riley as Sonim’s financial advisor, Sonim received non-binding indications of interest and letters of intent from potential strategic partners (including from Party A and from Party C (each as defined below), several of which were sent by Party C to Sonim during this period), and the Board held multiple special meetings to discuss and consider the terms of such non-binding indications of interest and letters of intent.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of The Board of Directors

As required under the Nasdaq Capital Market (“Nasdaq”), and our Corporate Governance Guidelines, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. In addition, applicable Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating committees be independent within the meaning of applicable Nasdaq rules. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act.

Consistent with these considerations, our Board undertook a review of the independence of each director and considered whether any director has a relationship which, in the opinion of the Board, would interfere with the exercise of judgment in carrying out the responsibilities of a director. After review of all relevant transactions or relationships between each director, or any of his or her family members, and the Company, its senior management, and its independent registered public accounting firm, the Board has affirmatively determined that the following directors are independent directors within the meaning of the applicable Nasdaq listing standards: Messrs. Cassano, Howe, Mulica, Principe, Steenstra, and Wang.

In making these determinations, our Board considered certain relationships and transactions that occurred in the ordinary course of business between the Company and entities with which some of our directors are or have been affiliated. The Board determined that such transactions would not impair the particular director’s independence or interfere with the exercise of independent judgment in carrying out director responsibilities. The Board determined that Mr. Liu, subsequently discussedby virtue of his employment with the same withCompany as Chief Executive Officer, is not an independent director.

Board Leadership Structure

The Board of the Company has an independent chair, Jeffrey Wang. As Board Chair, Mr. Tirva. Thereafter, Mr. Liu introduced Mr. TirvaWang has broad authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Wang family.

On November 1, 2021, Sonim andBoard. Accordingly, the Board Chair has substantial ability to shape the work of the Board. Peter Liu, the Company’s Chief Executive Officer, currently serves as our principal executive officer. The Company believes that having an entity associated with Purchaser entered into a One-Way Non-Disclosure Agreement, whichdid not include a standstill provision. Thereafter, representativesindependent Board Chair reinforces the independence of Sonim had periodic discussions with representatives of Purchaser regarding a potential strategic transaction between Sonim and Purchaser, but such discussions ceased prior to November 15, 2021.

On November 15, 2021, Sonim opened its ATM program for the sale of additional shares of common stock of Sonim and halted such program on November 16, 2021 as a result of Sonim’s stock price being below the minimum stock price established by the Board in the ATM program.

On December 3, 2021, the Board held a special meeting. Also present were members of management and a representative of O’Melveny. The Board discussed the current statusits oversight of the ATM programbusiness and approved adjustingaffairs of the ATM floor priceCompany. In addition, the Company believes that having an independent Board Chair creates an environment that is more conducive to an amount below $1.00 per share.

On December 6, 2021, representativesobjective evaluation and oversight of Purchaser delivered to Sonim, an unsolicited non-binding letter of intent, which we refer to herein asmanagement’s performance, increasing management accountability and improving the “Initial Purchaser Offer”, which provided (among other things): (a) for the investment of $15 million in Sonim for at least 51% ownership at an above market price, with the transaction closing in two tranches whereby at the first closing the Purchaser would invest $5 million and at the second closes the Purchaser would invest $10 million (which would be 6 months after the first closing, (b) as a condition to the first closing, Mr. Liu, be appointed the chief executive officer of Sonim (c) all transaction expenses of Purchaser are paid from proceeds from the transaction and (d) that Purchaser would be entitled to indemnification. Sonim did not discuss with Purchaser this non-binding letter of intent at this time.

Also on January 5, 2022, management and representatives of Party F held a meeting during which management presented on Sonim.

On January 7, 2022, the Board held a special meeting. Also present were members of management and a representative of O’Melveny. The Board discussed, together with management, the financial position of Sonim as well as a presentation prepared by management regarding the same, including that Sonim’s then current cash position was approximately $10 million, but that management believed that Sonim’s cash position would trend downward toward approximately $2 million in the second quarter of 2022 without any additional cash from the ATM program. The Board then discussed that (i) Sonim had sufficient cash to continue operations at its current spending rates until the end of June 2022, but did not expect to have sufficient cash to launch its new products in the fourth quarter of 2022, (ii) that the ATM program had been generally successful in raising capital to continue operations, but that with the end of 2021, Sonim would not continue the ATM program until the 2021 audit was completed and publicly disclosed and (iii) that this period provided an opportunity for Board to consider potential strategic transactions. The Board then discussed the Initial Purchaser Offer and the potential for Sonim to pursue a potential strategic transaction. Following such discussion, the Board determined that it was advisable andmonitor whether management’s actions are in the best interests of the Company and its stockholders to evaluate and consider potential strategic transactions and, in lightstockholders. As a result, the Company believes that having an independent Board Chair can enhance the effectiveness of the pending 2021 auditBoard as a whole.

Role of the Board in Risk Oversight

One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the desirenature and level of risk appropriate for the Company. Our Audit Committee has the responsibility to pursue a potential strategic transaction,consider and discuss our major financial risk exposures and the steps our management has taken to haltmonitor and control these exposures, including guidelines and policies to govern the ATM program at this time.

Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Typically, the applicable Board committees meet at least annually with the employees responsible for risk management in the committees’ respective areas of oversight.

Riley had been engaged by Party F for a financing matter unrelated to a potential strategic transaction between Sonim and Party F.

Riley and Party F and determined that, because the relationship with Party F was unrelated to a potential strategic transaction with Sonim, that B. Riley had not received any fees from Party F and that B. Riley was not actively advising Party F (notwithstanding that a formal engagement was in effect), the Board determined that it was advisable and in the best interests of the Company and its stockholders to continue to retain B. Riley as its financial advisor during this process. The Board then discussed the Initial Purchaser Offer and decided to not make any decisions at this point regarding the Initial Purchaser Offer and to discuss further at the next special meeting of the Board.

On February 11, 2022, management and representatives of Party A held a meeting during which management provided representatives of Party A with additional information on Sonim.

Riley, on behalf of Sonim, a non-binding letter of intent providing for the acquisition of certain assets of Sonim for $10 million, payable in cash. The non-binding letter of intent stated that Party F may request that certain key employees of Sonim agree to remain with the business following the closing of a transaction and that certain key members of Sonim’s management team will have the opportunity to assume expanded leadership roles after the transaction.

On February 15, 2022, the Board held a special meeting. Also present was a member of management, representatives of O’Melveny and representatives of B. Riley. At the request of the Board, representatives of B. Riley reviewed a summary of the offers received from Purchaser, Party C and Party F to date. The Board did not discuss the offers from Party A at this time as any potential strategic transaction with Party A was dependent on first completing a sale of substantially all of Sonim’s assets. The Board discussed that the offer from Party F was $10 million for certain assets of Sonim, but that Sonim would retain the public company shell should it desire to pursue a potential “reverse merger” transaction with Party A or another counterparty. The Board discussed that the value of such a potential public company shell could be approximately $20 million and that with that assumption, the offer from Party F could result in an implied valuation of Sonim of approximately $39 million (taking into account assets that would be retained by Sonim, including (among others) cash and accounts receivable, and taking into account liabilities that would remain with Sonim following such transaction). The Board discussed that while pursuing a potential strategic transaction with Party F could result in an implied valuation of Sonim equal to approximately $39 million, such value was dependent not just on consummating a transaction with Party F, but also effecting a “reverse merger” thereafter with Party A or another counterparty and that there is meaningful deal risk in completing that transaction. The Board then discussed the Initial Purchaser Offer, together with the presentation provided by Purchaser on February 9, 2022. The Board noted that the presentation included projections of Sonim taking into account the investment by Purchaser, prepared by Purchaser, and the Board expressly stated that the Board would not rely on such projections and instructed B. Riley likewise not to rely on such projections. The Board discussed that the implied valuation of Sonim based on the Initial Purchaser Offer was between $27.1 million to $39.3 million (with such range due to Sonim’s future cash flows discounted at a range of different discount rates). The Board then discussed that the implied valuation of Sonim based on Party C’s offer delivered on January 24, 2022 was approximately $32.2 million. Following such discussion, the Board instructed representatives of B. Riley to communicate to Party C and Party F, separately, that each should provide their best and final offers. The Board also stated that B. Riley should continue to work with Party A on negotiating a potential “reverse merger” transaction and that the signing of any such transaction with Party A should be subject to resolutionsophistication requirements of the SEC Matter.and Nasdaq listing rules. In addition, our Board has determined that Mr. Cassano and Mr. Howe are each an audit committee financial expert, as defined by SEC rules and regulations.

The Board also discussed the terms of the non-binding offer received from Purchaser on February 9, 2022, including the size of the investment, the percentage ownership of the Purchaser based on the size of such investment, the desire to have certain members of the Board continue as members of the Board following the closing of such potential investment transaction until the resolution of the SEC Matter given the historical knowledge of the current members of the Board regarding the SEC Matter, that Purchaser would pay for its own expenses out of investment transaction proceeds and Purchaser’s request for indemnification. Following such discussion, the Board instructed that the non-binding offer from the Purchaser be revised to provide (a) that the investment amount be $17.5 million for the purchase of 48% ownership of Sonim, which will close in one tranche, (b) that the per share purchase price be $0.98 per share, (c) that certain current directors of Sonim would continue on the Board following the closing until resolution of the SEC Matter, (d) that Purchaser will pay its own expenses, which cannot be paid out of the investment transaction proceeds and (e) that the right of Purchaser to indemnification be removed.

On February 26, 2022, the Board held a special meeting. Also present was a member of management, a representative of O’Melveny and representatives of B. Riley. At the request of the Board, representatives of B. Riley provided an update regarding the status of discussions with Party C and Party F. Representatives of B. Riley reported to the Board that Party C had not submitted any additional indication of interest or letter of intent since the non-binding indication of interest provided on January 24, 2022 and that representatives of B. Riley had instructed Party C to formulate a valuation and deal structure for a potential strategic transaction with Sonim, but that, to date, Party C had not done so. Representatives of B. Riley then discussed the non-binding letter of intent delivered by Party F on February 11, 2022 to acquire certain assets of Sonim and that since delivery of such letter on February 11, 2022, Party F had verbally increased its offer price for such assets from $10 million to $11.25 million. Representatives of B. Riley reported that Party F had stated that it would not increase its offer price beyond $11.25 million for such assets of Sonim. Representatives of B. Riley then discussed that a call was scheduled with representatives of Party F for March 1, 2022 regarding the potential transaction structure. The Board then discussed that if Sonim were to pursue a potential strategic transaction with Party F, following the closing thereof, it may seek a potential “reverse merger” transaction whereby, as a public shell company with no further operations, a private company, such as Party A, could merge with and into Sonim (or a wholly owned subsidiary thereof) such that the merging private company would then become a public company. Representatives of B. Riley and of O’Melveny then reviewed for the Board the revised Initial Purchaser Offer, which was made available to the Board prior to the meeting. The Board then discussed the terms of such revised Initial Purchaser Offer. The Board also discussed that, to date, Purchaser had not requested exclusivity. The

Board then discussed that Purchaser had been in contact with Mr. Liu and that it was Purchaser’s intention that Mr. Liu become the Chief Executive Officer of Sonim. The Board discussed that, as of such time, to its knowledge and based on inquires made of representatives of Purchaser, Mr. Liu was not currently expected to be an equityholder in Purchaser. Following such discussion, the Board instructed representatives of B. Riley to (a) send the revised offer to Purchaser and (b) to continue discussions with Party C and Party F regarding a potential strategic transaction, including encouraging Party C to provide a valuation and deal structure for a potential strategic transaction with Sonim and to hold the conference call with representatives of Party F on March 1, 2022. The Board stated that if Purchaser requested exclusivity, it would evaluate such request at such time.

Later on February 26, 2022, representatives of B. Riley, on behalf of Sonim, delivered to representatives of Purchaser a revised draft of the Initial Purchaser Offer, which we refer to herein as the “Revised Offer”, whereby Sonim revised the draft to provide: (a) that the investment amount is $17.5 million for the purchase of 48% ownership of Sonim, which will close in one tranche, (b) that the per share purchase price be $0.98 per share, (c) that certain current directors of Sonim would continue as members of the Board following the closing until resolution of the SEC Matter, (d) that Purchaser will pay its own expenses, which cannot be paid out of the investment transaction proceeds and (e) that the right of Purchaser to indemnification is removed.

On February 28, 2022, representatives of Purchaser delivered to representatives of B. Riley, on behalf of Sonim, a response to the Revised Offer, which we refer to herein as “Purchaser’s Response”, whereby it was communicated that (a) Purchaser accepted the increased investment amount of $17.5 million, but stated that it required that such investment result in Purchaser owning 52% of the outstanding capital stock of Sonim, which results in an effective price per share of approximately $0.84, (b) Purchaser desired that the transaction be closed in two tranches, the first being for $12.5 million and the second occurring in the third calendar quarter of 2022 for $5 million, (c) Purchaser reserves on points relating to the SEC Matter and indemnification rights and (d) Purchaser desired that Sonim start to implement its business plan as early as possible and that Sonim would be cooperative and supportive of such strategy, including appointing Mr. Liu as the Chief Executive Officer of Sonim concurrent with signing the Subscription Agreement.

On March 1, 2022, representatives of B. Riley and O’Melveny discussed with representatives of Party F potential transaction structures and certain other potential deal terms relating to a potential strategic transaction between Sonim and Party F.

Later on March 1, 2022, the Board held a special meeting. Also present was a member of management, a representative of O’Melveny and representatives of B. Riley. At the request of the Board, representatives of B. Riley reviewed the status of the potential strategic transactions with Party C, Party F and Purchaser. Representatives of B. Riley reported to the Board that Party C had not yet formed a conclusion regarding an updated proposal for a potential strategic transaction with Sonim. Representatives of B. Riley and of O’Melveny then discussed the conference call they had earlier in the day with representatives of Party F, including discussion topics relating to the structure of a transaction with Party F, the assets that would be acquired, the liabilities that would be assumed (if any) and whether Party F would be entitled to indemnification. Representatives of B. Riley informed the Board that Party F had reiterated its request for 30 days of exclusivity. Representatives of B. Riley then summarized for the Board the Purchaser’s Response. The Board discussed that Purchaser had communicated the desire to start to implement Purchaser’s business plan as early as possible and that Purchaser did not want to wait until May 2022 or later to start implementing its business plan for Sonim. The Board then discussed the request to appoint Mr. Liu as Chief Executive Officer concurrent with the signing of the Subscription Agreement. The Board then asked representatives of B. Riley whether Purchaser had requested exclusivity and B. Riley responded that Purchaser had not made a request to date for exclusivity. The Board then further discussed the Purchaser’s Response, including (among other things) that (i) Purchaser had previously provided to the Board a presentation providing information regarding Purchaser’s business plans for the go-forward company, (ii) that the potential transaction with Purchaser allowed Sonim’s current stockholders to continue to hold an equity interest in Sonim and may realize any potential increase in value of Sonim should Purchaser achieve some or all of its

business plan for Sonim, (iii) the implied value of Sonim of approximately $33.7 million in the potential transaction with Purchaser, (iv) that Party C had not moved with as much speed as Purchaser and had not provided a final letter of intent setting forth valuation and structure for a transaction and (v) that the transaction with Party F involved unique complexity and uncertainty than the transaction with Purchaser as the transaction with Party F required a sale of assets (including likely third party consents to consummate the transaction) and following such sale, the Board would look to sell the Sonim “shell” company in a reverse merger. Following such discussion, the Board instructed representatives of B. Riley to inform representatives of Purchaser that the Board would continue to pursue a potential strategic transaction with Purchaser pursuant to the terms outlined in the Revised Offer, as modified by Purchaser’s Response, subject to further discussion regarding the implementation of Purchaser’s business plan and appointing Mr. Liu Chief Executive Officer of Sonim prior to the first closing. Representatives of B. Riley then left the meeting and the Board discussed the desire to have B. Riley deliver a fairness opinion in connection with the contemplated transaction with Purchaser. The Board stated that it was desirable and in the best interests of Sonim and its stockholders for the Board to obtain a fairness opinion from B. Riley in connection with the contemplated transaction with Purchaser.

On March 3, 2022, Sonim granted access to an electronic data room to Party C, but prior to such time, representatives of B. Riley and management were delivering to Party C diligence information and materials.

Also on March 3, 2022, representatives of Venable, on behalf of Purchaser, requested that Sonim grant Purchaser exclusivity through March 31, 2022 and delivered a draft exclusivity agreement. Thereafter, representatives of B. Riley alerted the Board to the request for exclusivity from representatives of Venable, on behalf of Purchaser. The members of the Board expressed that they were willing to agree to exclusivity, but wanted the exclusivity period to expire on March 15, 2022. Representatives of O’Melveny then revised the draft exclusivity agreement to, among other changes, reflect the expiration of the exclusivity period as March 15, 2022 and delivered the revised exclusivity agreement to representatives of Venable. Representatives of Venable never responded to the revised draft of the exclusivity agreement and prior to the execution of the Subscription Agreement, Sonim never entered into exclusivity with Purchaser.

On March 4, 2022, representatives of O’Melveny discussed with representatives of Venable the SEC Matter.

Also on March 4, 2022, representatives of Party C delivered to representatives of B. Riley, on behalf of Sonim, an updated non-binding indication of interest, which provided (among other things) that Party C was seeking to acquire selected accounts receivable and selected inventory (including finished goods inventory and PCBA (printed circuit board assembly) inventory, subject to further diligence), which it stated had a value of approximately $14.395 million. The indication of interest again did not include a specific offer price. The non-binding indication of interest also provided that all current carrier and key OEM and supplier contracts under which Sonim operates would be included as part of the asset transfer. In addition, Party C stated in the non-binding indication of interest that Party C would be interested in retaining select employees and that any costs associated with the termination of the employment of any employees would be the responsibility of Sonim. No specific persons were identified as employees that Party C was potentially interested in retaining.

On or around March 4, 2022, representatives of B. Riley discussed with representatives of Party C the non-binding indication of interest sent by Party C on that day, including that Party C needed to improve its offer and that it would be helpful if Party C could conduct further due diligence regarding the current financial position of Sonim.

On March 7, 2022, representatives of O’Melveny delivered the initial draft of the Subscription Agreement to representatives of Venable, which included, among other things (a) a provision providing that at least two current directors of the Board (or one current Director and Mr. Tirva) would continue to serve on the Board and would constitute the sole members of a select matters committee of the Board, which would have sole and exclusive authority to address, negotiate and resolve the SEC Matter, (b) non-solicitation and deal protection provisions and related termination rights and fees, including that the Sonim termination fee would equal $300,000 payable if

In the Subscription Agreement, the Purchaser representedCompany on June 28, 2022, and warranted to Sonim, among other things, that, asconsummation of the date of the Subscription Agreement, the Purchaser has immediately available funds to pay the first purchase price and the second purchase price. Sonim has been made aware that, although the Wang family has funds sufficient to pay the first purchase price and the second purchase price, such funds are not in a bank account controlled by the Purchaser. Sonim has requested the Purchaser deposit funds sufficient to pay the first purchase price and second purchase price in a bank account controlled by the Purchaser. The Purchaser has informed Sonim that it is in the process of establishing a bank account and intends to deposit such immediately available funds in such bank account prior to the first closing.

Reasons for the Transaction; Recommendation of the Board

The Board recommends that you vote “FOR” the Transaction Proposal.

The Board held numerous meetings at which the business strategies, opportunities and challenges of the Company were evaluated and potential strategic alternatives were considered.

At a meeting held on April 13, 2022, after careful consideration, the Board unanimously (i) determined that the Subscription Agreement and the transactions contemplated thereby are fair to and in the best interests of the Company’s stockholders, (ii) adopted and declared advisable the Subscription Agreement and the transactions contemplated thereby and (iii) resolved, subject to certain provisions of the Subscription Agreement, to recommend that the Company’s stockholders adopt the Subscription Agreement, all upon the terms and subject to the conditions set forth therein.

In evaluating and reaching its decision, the Board consulted with senior management and the representatives of O’Melveny & Myers LLP and B. Riley at various times and considered a number of factors, including the following material factors (not in any relative order of importance) that the Board believes support its decision to approve the transaction and adopt the Subscription Agreement:

Certain Company Forecasts

Sonim does not, as a matter of course, make public disclosure of detailed forecasts or projections of its expected financial performance for extended periods due to, among other things, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. However, in connection with Sonim’s evaluation of potential strategic transactions involving Sonim, Sonim management prepared certain projections and estimates of future financial and operating performance with respect to Sonim’s fiscal year 2022, 2023 and 2024 (which we refer to herein as the “management projections”). Sonim made available the management projections to the Board and B. Riley. In addition, management prepared certain projections and estimates of future financial and operating performance with respect to Sonim’s fiscal year 2022, 2023 and 2024 as if the Sonim business had been sold in a “carve-out” transaction whereby such business would no longer be subject to customary overhead costs and expenses of a public company, which we refer to herein as the “carveout projections”. The management projections were derivedmaterial changes from the carveout projections, with management updating the management projections to reflect a non-carve-out strategic transaction in which Sonim continues to incur customary overhead expenses of a publicly listed company, which resulted in an add back of such expenses, and with management updating the management projections to reflect results of operations since the preparation of the carveout projections and refining the management projections to reflect the best currently available estimates and judgments of Sonim’s management at such time. The management projections were not shared with AJP Holdings or any other potential strategic partner, but the carveout projections were shared with AJP Holdings and certain other potential strategic partners.

A summary of the management projections is being included in this proxy statement because they were made available to the Board and B. Riley and a summary of the carveout projections is being included in this proxy statement because they were made available to AJP Holdings and other potential strategic partners. This information is not intended to influence your decision whether to vote for or against the transaction proposal. The inclusion of this information should not be regarded as an indication that the Board, its advisors or any other person considered, or now considers, the management projections or the carveout projections to be material or to be a reliable prediction of actual future results, and neither management projections nor the carveout projections should be relied upon as such. The management projections and the carveout projections are subjective in many respects. There can be no assurance that the management projections or the carveout projections will be realized or that actual results will not be significantly higher or lower than reflected in the management projections or the carveout projections. The management projections and the carveout projections cover multiple years and such information by its nature becomes subject to greater uncertainty with each successive year. As a result, the inclusion of the management projections and the carve out projections in this proxy statement should not be relied on as necessarily predictive of actual future events.

The management projections were prepared on a stand-alone basis and do not take into account any of the transactions contemplated by the subscription agreement, including the acquisition of common stock and associated expenses, or Sonim’s compliance with its covenants under the subscription agreement. The management projections assume sufficient liquidity to continue to operate through the planning period, which would require Sonim to raise additional capital. For these reasons and for the reasons described above, actual results likely will differ, and may differ materially, from those contained in the management projections.

The carveout projections were prepared on a stand-alone basis, but do assume that the Sonim business is sold to a strategic partner whereby customary overhead costs of a public company would no longer be applicable. For these reasons and for the reasons described above, actual results likely will differ, and may differ materially, from those contained in the carveout projections.

The management projections were prepared by, and are the responsibility of, Sonim’s management for internal use and use by B. Riley. The carveout projections were prepared by, and are the responsibility of, Sonim’s management, but such projections were not relied upon by the Sonim Board or B. Riley and were provided to AJP Holdings and certain other potential strategic partners. The management projections were (i) used by B. Riley in its financial analyses undertaken in connection with rendering its opinion to the Board, (ii) not prepared for purposes of public disclosure and (iii) not prepared on a basis designed to comply with published guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial data, published guidelines of the SEC (including those regarding forward-looking statements and the use of non-GAAP measures) or GAAP. Moss Adams LLP, Sonim’s independent registered public accounting firm, has not audited, reviewed, examined, compiled nor applied agreed-upon procedures with respect to the management projections or the carveout projections contained in this proxy statement and, accordingly, Moss Adams LLP does not express an opinion or any other form of assurance with respect thereto. Further, the management projections and the carveout projections include non-GAAP financial measures. Non-GAAP financial measures are not prepared in accordance with GAAP and should be considered as a supplement to, not a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.

Although the management projections and carveout projections presented below are presented with numerical specificity, they are estimates of future performance and not historical facts. The management projections and the carveout projections were based on numerous variables and assumptions that were deemed to be reasonable as of the respective dates when such projections were finalized. Realization of such assumptions is inherently uncertain and may be beyond the control of Sonim. Important factors that may affect actual results and cause the management projections or the carveout projections not to be achieved include, but are not limited to, risks and uncertainties relating to Sonim’s business (including, without limitation, risks relating to competition; customer risks; scale; market and product diversification; breadth of solution offerings; technology risks; innovation demands of customers; organic growth opportunities; inorganic opportunities; and industry consolidation and other factors described or referenced under “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 17. In the view of Sonim’s management, the management projections had been reasonably prepared on a basis reflecting the best currently available estimates and judgments of Sonim’s management of the future financial performance of Sonim and other matters covered thereby. In the view of Sonim’s management, the carveout projections had been reasonably prepared on a basis reflecting the best currently available estimates and judgments of Sonim’s management of the future financial performance of Sonim and other matters covered thereby, taking into account that the Sonim business was sold in a carve-out transaction and was no longer subject to customary overhead costs of a public company. In addition, the assumptions underlying the management projections and the carveout projections are subject to change and have not been revised since their preparation to reflect any changes in Sonim’s business, industry performance, the legal or regulatory environment, general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated as the management projections and the carveout projections were prepared. Neither Sonim nor AJP Holding undertakes any obligation, except as required by law, to update or otherwise revise the management projections or the carveout projections to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error or to not be appropriate, or to reflect changes in Sonim’s business, industry performance, the legal or regulatory environment, or general business or economic conditions. There can be no assurance that the management projections or the carveout projections will be realized or that Sonim’s future financial results will not materially vary from the management projections or the carveout projections.

Management Projections

The following is a summary of the management projections prepared by Sonim’s management and provided to the Board and B. Riley.

Carveout Projections

The following is a summary of the carveout projections prepared by Sonim’s management and provided to the Board and B. Riley, each of which did not rely on such projections in connection with its consideration of the subscription agreement and the transactions contemplated thereby, and was provided to AJP Holdings and certain other potential strategic partners.

Opinion of B. Riley Securities, Inc.

On April 13, 2022, B. Riley rendered to the Board its oral opinion (which was subsequently confirmed in writing by delivery of B. Riley’s written opinion dated April 13, 2022), to the effect that, as of April 13, 2022, and based upon and subject to the qualifications, limitations, assumptions and other matters considered by B. Riley in connection with the preparation of the opinion, the Aggregate Consideration to be received by the Company in exchange for the Purchased Shares in the transaction pursuant to the Subscription Agreement was fair from a financial point of view to the Company.

B. Riley’s opinion was directed to the Board (in its capacity as such) and only addressed the fairness, from a financial point of view, to the Company of the Aggregate Consideration to be received by the Company in exchange for the Purchased Shares in the transaction pursuant to the Subscription Agreement and did not address any other aspect or implication of the transaction, the Subscription Agreement or any other agreement or understanding entered into in connection with the transaction or otherwise. The summary of B. Riley’s opinion in this proxy statement is qualified in its entirety by reference to the full text of its written opinion, which is included as Annex B to this proxy statement and sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by B. Riley in preparing its opinion. However, neither B. Riley’s written opinion nor the summary of its opinion and the related analyses set forth in this proxy statement is intended to be, and they do not constitute, a recommendation to the Board, the Company, any security holder of the Company or any other person as to how to act or vote on any matter relating to the transaction or otherwise.

For purposes of B. Riley’s opinion, the Company advised B. Riley and directed B. Riley to assume (i) the Company’s consolidated financial statements as of and for the year ended December 31, 2021, were prepared on the assumption that the Company would continue as a going concern, (ii) the Company was experiencing significant liquidity issues, (iii) the Company had not obtained, and did not expect to obtain, alternative financing on terms more favorable to the Company from a financial point of view, and (iv) in the absence of the transaction, or alternative financing for which the Company had not arranged and did not believe it could arrange to obtain on terms more favorable to the Company at the time, the Company’s ability to function as a going-concern would likely be severely impaired.

In arriving at its opinion, B. Riley, among other things:

In preparing its opinion, at the Company’s direction, B. Riley relied, without assuming responsibility or liability for independent verification, upon the accuracy and completeness of all financial and other information available from public sources and all other information provided to B. Riley or otherwise discussed with or reviewed by B. Riley. Company management advised B. Riley and, at the Company’s direction, B. Riley assumed that the Status Quo Projections were reasonably prepared in good faith and represented Company management’s best currently available estimates and judgments with respect to the future financial performance of the Company in the absence of the transaction. In addition, at the Company’s direction, B. Riley assumed that the Financing Plan Projections were reasonably prepared in good faith and represented Purchaser management’s best currently available estimates and judgments with respect to the future financial performance of the Company giving effect to the transaction and the business strategy contemplated thereby. B. Riley assumed no responsibility for and expressed no view or opinion as to the Status Quo Projections, the Financing Plan Projections or the respective assumptions on which they were based. At the Company’s direction, B. Riley used and relied upon the Status Quo Projections for purposes of its analyses and opinion and assumed that the Status Quo Projections provided a reasonable basis upon which to evaluate the Company and the proposed transaction. B. Riley also assumed that there had been no changes in the assets, financial condition, results of operations, business or prospects of the Company since the respective dates of the last financial statements and other information, financial or otherwise, made available to B. Riley that would be material to its analyses or opinion, and that there was no information or any facts or developments that would make any of the information reviewed by B. Riley inaccurate, incomplete or misleading.

B. Riley was not asked to, and did not, undertake an independent verification of any information provided to or reviewed by it, nor was B. Riley furnished with any such verification, and B. Riley did not assume any responsibility or liability for the accuracy or completeness such information. B. Riley did not make an independent evaluation or appraisal of the assets or the liabilities (contingent or otherwise) of the Company, nor did B. Riley evaluate the solvency of the Company under any state or federal laws. B. Riley did not undertake any independent analysis of any pending or threatened litigation, possible unasserted claims or other contingent liabilities to which the Company was a party or may have been subject, including, without limitation, the ongoing investigation of the Company by the SEC, and B. Riley’s opinion made no assumption concerning, and therefore did not consider, the possible assertion of claims, outcomes or damages arising out of any such matters, including, without limitation, the additional shares of common stock that may become issuable to Purchaser in connection therewith.

B. Riley also assumed, with the Company’s consent, that (i) in the course of obtaining any regulatory or third party consents or approvals in connection with the transaction, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on the Company or the contemplated benefits of the transaction, (ii) the representations and warranties made by the parties in the Subscription Agreement were accurate and complete in all respects; (iii) each party to the Subscription Agreement would perform all of its

covenants and obligations thereunder; and (iv) the transaction would be consummated in accordance with the terms of the Subscription Agreement, without waiver, modification or amendment of any term, condition or provision thereof. B. Riley also assumed that the Subscription Agreement, when executed by the parties thereto, would conform to the draft reviewed by B. Riley in all respects material to its analyses and opinion. B. Riley is not a legal, tax or regulatory advisor and relied upon, without independent verification, the assessments of the Company and its legal, tax and regulatory advisors with respect to such matters. Without limitation to the foregoing, with the Company’s consent, B. Riley did not evaluate the impact, if any, of the transaction on the Company’s ability to utilize its net operating loss carryforwards to reduce future tax liabilities.

B. Riley’s opinion was limited to the fairness, from a financial point of view, to the Company of the Aggregate Consideration to be received by the Company for the Purchased Shares in the transaction pursuant to the Subscription Agreement, and B. Riley expressed no view or opinion as to the fairness of the transaction to the holders of any class of securities, creditors or other constituencies of the Company. B. Riley’s opinion did not address any other aspect or implication of the transaction, the Subscription Agreement, or any other agreement or understanding entered into in connection with the transaction or otherwise. B. Riley also expressed no view or opinion as to the fairness of the amount or nature of the compensation to any of the Company’s officers, directors or employees, or any class of such persons, relative to the Aggregate Consideration or otherwise. B. Riley expressed no view or opinion as to the prices or range of prices at which Company common stock may trade at any time. Furthermore, B. Riley did not express any opinion as to the impact of the transaction on the solvency or viability of the Company or the Purchaser, or the ability of the Company or the Purchaser to pay its obligations when they become due.

B. Riley’s opinion was necessarily based upon economic, market, monetary, regulatory and other conditions as they existed and could be evaluated, and the information made available to B. Riley, as of the date of its opinion. Although subsequent developments may affect its opinion, B. Riley does not have any obligation to update, revise or reaffirm its opinion. As the Company was aware, the credit, financial and stock markets were experiencing significant volatility, and B. Riley expressed no view or opinion as to any potential effects of such volatility on the Company or the proposed transaction.

B. Riley’s opinion was for the information of the Board (in its capacity as such) in connection with its consideration of the proposed transaction. B. Riley’s opinion does not constitute a recommendation to the Board, the Company, any security holder of the Company or any other person as to how to act or vote on any matter relating to the transaction or otherwise including, without limitation, whether or not to participate in any offering of securities by the Company. B. Riley’s opinion did not address the relative merits of the transaction as compared to alternative transactions or strategies that might have been available to the Company or any other party to the transaction, nor did it address the underlying business decision of the Board, the Company or any other party to effect the transaction.

In preparing its opinion to the Board, B. Riley performed a variety of analyses, including those described below. The summary of B. Riley’s analyses is not a complete description of the analyses underlying B. Riley’s opinion. The preparation of such an opinion is a complex process involving various quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytical methods employed and the adaptation and application of these methods to the unique facts and circumstances presented. As a consequence, neither B. Riley’s opinion nor its underlying analyses is readily susceptible to summary description. B. Riley arrived at its opinion based on the results of all analyses undertaken by it and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any individual analysis, methodology or factor. While the results of each analysis were taken into account in reaching B. Riley’s overall conclusion with respect to fairness, B. Riley did not make separate or quantifiable judgments regarding individual analyses. Accordingly, B. Riley believes that its analyses and the following summary must be considered as a whole and that selecting portions of its analyses, methodologies and factors, without considering all analyses, methodologies and factors, could create a misleading or incomplete view of the processes underlying B. Riley’s analyses and opinion.

In performing its analyses, B. Riley considered general business, economic, industry and market conditions, financial and otherwise, and other matters as they existed on, and could be evaluated as of, the date of its opinion. No company, transaction or business used in B. Riley’s analyses for comparative purposes is identical to the Company or the proposed transaction and an evaluation of the results of those analyses is not entirely mathematical. The estimates contained in the Status Quo Projections and the implied value reference ranges indicated by B. Riley’s analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold, which may depend on a variety of factors, many of which are beyond the control of the Company. Much of the information used in, and accordingly the results of, B. Riley’s analyses are inherently subject to substantial uncertainty.

B. Riley’s opinion was only one of many factors considered by the Board in evaluating the proposed transaction. Neither B. Riley’s opinion nor its analyses were determinative of the Aggregate Consideration or of the views of the Board or management with respect to the transaction or the Aggregate Consideration. The type and amount of Aggregate Consideration payable in the transaction were determined through negotiation between the Company and Purchaser, and the decision to enter into the Subscription Agreement was solely that of the Board.

Material Financial Analyses

The following is a summary of the material financial analyses performed by B. Riley in connection with the preparation of its opinion and reviewed with the Board on April 13, 2022. The order of the analyses does not represent relative importance or weight given to those analyses by B. Riley. The analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the analyses. Considering the data in the tables below without considering the full narrative description of the analyses, as well as the methodologies underlying, and the assumptions, qualifications and limitations affecting, each analysis could create a misleading or incomplete view of B. Riley’s analyses.

For purposes of its analyses, B. Riley reviewed a number of financial metrics, including:

Unless the context indicates otherwise, enterprise values and equity values used in the selected companies analysis described below were calculated using the closing price of the Company’s common stock and the common stock of the selected companies listed below as of April 13, 2022, and transaction values for the selected transactions analysis described below were calculated on an enterprise value basis based on the value of the equity consideration in the announced transaction and other publicly available information at the time of the announcement. The estimates of the future financial performance of the Company relied upon for the financial analyses described below were based on the Status Quo Projections. The estimates of the future financial performance of the selected companies listed below were based on publicly available research analyst estimates for those companies.

Selected Companies Analysis. B. Riley reviewed certain financial data for selected companies with publicly traded equity securities that B. Riley deemed relevant. The financial data reviewed included enterprise value as a

multiple of revenue for the year ending December 31, 2021, or “2021 Revenue,” and enterprise value as a multiple of estimated revenue for the year ending December 31, 2022, or “2022E Revenue.”

The selected companies and corresponding multiples were:Amended 2019 Plan:

As of the Record Date the number of shares of common stock authorized for issuance but unissued under the 2019 Plan is [318,458], and the number of shares of common stock authorized for issuance but unissued under the 2019 Plan is [32,857]. As of the Record Date, the Company has outstanding stock options to purchase approximately [83,356] shares of common stock, [235,102] shares of common stock subject to outstanding restricted stock units and warrants to purchase [2] shares of common stock, all of which were granted under the 2019 Plan and various other prior plans and non-plan agreements.

Why You Should Vote for the Second Amended 2019 Plan

Equity Awards Are an Important Part of Our Compensation Philosophy

The Board believes that it is very important that our eligible employees, consultants and directors receive part of their compensation in the form of equity awards to foster their investment in us, reinforce the link between their financial interests and those of our other stockholders and maintain a competitive compensation program. Equity compensation fosters an employee ownership culture, motivates employees to create stockholder value and, because the awards are typically subject to vesting and other conditions, promotes a focus on long-term value creation. The equity incentive programs we have in place have worked to build stockholder value by attracting and retaining extraordinarily talented employees, consultants and directors. The Board believes we must continue to offer competitive equity compensation packages in order to attract and motivate the talent necessary for our continued growth and success.

We Expect to Continue to Experience Substantial Growth in Our Business

Our Board approved the Second Amended 2019 Plan to help ensure that we have sufficient shares available to attract and retain qualified employees to support our operations.

The Second Amended 2019 Plan Combines Compensation and Governance Best Practices Designed to Protect our Stockholders’ Interests

We recognize that equity compensation awards dilute stockholder equity and must be used judiciously. Our equity compensation practices are designed to be in line with industry norms, and we believe our historical share usage has been responsible and mindful of stockholder interests. Certain provisions in the Second Amended 2019 Plan are designed to protect our stockholders’ interests and to reflect corporate governance best practices including:

We Manage Our Equity Award Usage Carefully

The following table provides certain additional information regarding our equity incentive plans as of the Record Date.

Taking into account the results of the selected companies analysis, B. Riley applied selected multiple ranges of 0.2x to 1.3x to the Company’s 2021 revenue and 0.1x to 1.3x to the Company’s estimated 2022E revenue. The selected companies analysis indicated implied aggregate equity value reference ranges for the Purchased Shares of $10.0 million to $41.1 million, based on 2021 revenue, and $7.5 million to $46.0 million, based on estimated 2022E revenue, in each case as compared to the Aggregate Consideration of $17.5 million in the transaction pursuant to the Subscription Agreement.

Selected Transactions Analysis. B. Riley reviewed certain financial terms of certain transactions involving target companies that B. Riley deemed relevant. The financial data reviewed included enterprise value as a multiple of revenue for the last twelve months available prior to the date of announcement, or “LTM Revenue.”

The selected transactions and corresponding multiples were:

Taking into account the results of the selected transactions analysis, B. Riley applied a selected multiple range of 0.9x to 1.5x to the Company’s revenue for the last twelve months. The selected transactions analysis indicated an implied aggregate equity value reference range for the Purchased Shares of $29.7 million to $46.7 million, as compared to the Aggregate Consideration of $17.5 million in the transaction

The following table provides detailed information regarding the Subscription Agreement.

Discounted Cash Flow Analysis. B. Riley performed a discounted cash flow analysis of the Company based on the Status Quo Projections provided by the Company management. B. Riley applied ranges of terminal value multiples of 0.2x to 1.0x to the Company’s estimated 2024E revenue and 6.0x to 10.0x to the Company’s estimated 2024E adjusted EBITDA and, in each case, discount rates ranging from 30.0% to 40.0%. The discounted cash flow analysis indicated implied aggregate equity value reference ranges for the Purchased Shares of $0.6 million to $22.1 million, based on multiples of estimated 2024E revenue, and $3.8 million to $11.3 million, based on multiples of estimated 2024E adjusted EBITDA, in each case as compared to the Aggregate Consideration of $17.5 million in the transaction pursuant to the Subscription Agreement.

Additional Information

Illustrative Discount Paid Analysis. B. Riley performed a discount paid analysis of the Purchased Shares using the stock price discounts/premiums paid in 134 PIPE transactions involving U.S. public company issuers over the last seven years prior to April 13, 2022, including 115 small-cap transactions involving public companies with market caps of less than $500 million. B. Riley calculated the median discounts paid for the purchased shares relative to the issuer company’s single-day closing share price for the date one day prior to the announcement of the transaction. The median discount was (8.2%) for all transactions and (7.4%) for the small cap company transactions, in each case as compared to a premium of 20.0%, based on the price per share in the transaction of $0.84 and the Company’s closing price of $0.70 on April 13, 2022.

Taking into account the results of the illustrative discount paid analysis, B. Riley applied the median discounts indicated for all transactions and the small cap company transactions to the Company’s closing trading price of $0.70 on April 13, 2022. The discount paid analysis indicated illustrative aggregate equity reference values for the Purchased Shares of $13.4 million, based on the median discount for all transactions, and $13.5 million, based on the median discount for the small cap company transactions, in each case as compared to the Aggregate Consideration of $17.5 million in the transaction pursuant to the Subscription Agreement.
