Item 1.01 Entry into a Material Definitive Agreement.

Amended and Restated Merger Agreement

On July 2, 2026, SoundHound AI, Inc., a Delaware corporation (the “Company”), Lightspeed Merger Sub Inc., a Delaware corporation and an indirect wholly owned subsidiary of the Company (“Merger Sub I”), Lightspeed Merger Sub II Inc., a Delaware corporation and an indirect wholly owned subsidiary of the Company (“Merger Sub II” and, together with Merger Sub I, “Merger Subs”) and LivePerson, Inc., a Delaware corporation (“LivePerson”) entered into an Amended and Restated Merger Agreement (the “Amended and Restated Merger Agreement”), which amends and restates in its entirety the Merger Agreement, dated as of April 21, 2026, by and among the Company, Merger Sub I and LivePerson (the “Original Merger Agreement”). Pursuant to the Amended and Restated Merger Agreement, on the terms and subject to the conditions set forth in the Amended and Restated Merger Agreement, Merger Sub I will merge with and into LivePerson (the “First Merger”), with LivePerson surviving the First Merger as an indirect wholly owned subsidiary of the Company and, immediately following the First Merger, Merger Sub II will merge with and into LivePerson (the “Second Merger”, and, together with the First Merger, the “Mergers”), with LivePerson surviving the Second Merger as an indirect wholly owned subsidiary of the Company. All defined terms used in this summary of the Amended and Restated Merger Agreement that are not otherwise defined herein have the meanings ascribed to such terms in the Amended and Restated Merger Agreement.

Subject to the terms and conditions of the Amended and Restated Merger Agreement, at the date and time the First Merger becomes effective (the “First Effective Time”), each share of common stock, par value $0.001 per share, of LivePerson (“LivePerson Common Stock”) issued and outstanding immediately prior to the First Effective Time (other than certain excluded shares, including TASE Shares (as defined below)) will be automatically converted into the right to receive a number of shares of Class A common stock of the Company, par value $0.0001 per share (“Company Common Stock”) equal to (a) the Closing Merger Consideration (as defined below), divided by (b) the total number of shares of LivePerson Common Stock that are issued and outstanding, or that are issuable upon the conversion, exercise or settlement in full of any rights to acquire LivePerson Common Stock, as of immediately prior to the First Effective Time (such number of shares, the “Fully Diluted Common Number”, and the result of the calculation set forth in the foregoing clauses (a) and (b), the “Per Share Merger Consideration”).

The aggregate amount of consideration payable by the Company to holders of LivePerson Common Stock (other than certain excluded shares, including TASE Shares) in connection with the First Merger pursuant to the terms of the Amended and Restated Merger Agreement will be a number of shares of Company Common Stock equal to the quotient of (a) the Aggregate Consideration Amount (as defined below), divided by (b) the Company Closing Stock Price (the “Closing Merger Consideration”).

Consistent with the Original Merger Agreement, the “Aggregate Consideration Amount” refers to an amount equal to (a) $42,784,532.64, minus (b) the LivePerson Shortfall Cash (as defined below), plus (c) the aggregate dollar amount of the exercise prices of all In-the-Money Options (as defined below) (other than options assumed by the Company and converted into an option to acquire shares of the Company Common Stock, in accordance with the terms of the Amended and Restated Merger Agreement). Consistent with the Original Merger Agreement, “LivePerson Shortfall Cash” refers to an amount equal to (x) $74,000,000 (or, solely for purposes of the Amended and Restated Merger Agreement, $71,000,000 if the Closing occurs in July), minus (y) the aggregate principal amount of LivePerson’s 0% convertible notes due 2026 (the “2026 Convertible Notes”) repurchased by LivePerson between April 1, 2026 and the Closing Date (the figure resulting from clause (x) minus clause (y), “LivePerson Minimum Cash”), minus (z) the cash and cash equivalents on LivePerson’s balance sheet as of 12:01 a.m. Pacific Time on the Closing Date (net of certain LivePerson transaction expenses) (the foregoing clause (z), the “LivePerson Cash Balance”); provided that, if a negative number results from such calculation, “LivePerson Shortfall Cash” will be $0. Consistent with the Original Merger Agreement, the “Company Closing Stock Price” refers to the price per share of Company Common Stock derived from the average of the daily volume weighted average prices of a share of Company Common Stock on the Nasdaq on each of the ten (10) consecutive trading days ending on (and including) the trading day that is three (3) trading days prior to the Closing Date, rounded down to the nearest penny, as reported by Bloomberg (such price per share, the “Parent Closing VWAP Stock Price”); provided that, in the event such price per share (I) exceeds $12 per share, “Company Closing Stock Price” will be $12 per share or (II) falls below $7 per share, “Company Closing Stock Price” will be $7 per share.

Consistent with the Original Merger Agreement, the Amended and Restated Merger Agreement provides that, at the First Effective Time, (i) each option to purchase shares of LivePerson Common Stock (a “LivePerson Option”) with a per-share exercise price less than the product of the Per Share Merger Consideration multiplied by the Company Closing Stock Price (each, an “In-the-Money Option”) and held by any individual who is not an “employee” of the Company within the meaning of Form S-8 as of immediately after the date and time the Second Merger becomes effective (the “Second Effective Time”) will be entitled to receive the Per Share Merger Consideration applicable to the number of shares covered by such LivePerson Option, net of the applicable exercise price and less applicable tax withholdings; (ii) each LivePerson Option that is not an In-the-Money Option will be cancelled for no consideration; (iii) restricted stock units with respect to shares of LivePerson Common Stock (the “LivePerson RSUs”) held by non-employee directors of LivePerson and each LivePerson RSU that has vested but not yet settled will be entitled to receive the Per Share Merger Consideration in respect of each LivePerson RSU, less applicable tax withholdings; (iv) all other In-the-Money Options and LivePerson RSUs will be assumed by the Company and converted into corresponding awards denominated in shares of Company Common Stock in accordance with the terms set forth in the Amended and Restated Merger Agreement, which are consistent with the terms of the Original Merger Agreement, and (v) all warrants to purchase shares of LivePerson Common Stock will be cancelled for no consideration. Consistent with the Original Merger Agreement, the Amended and Restated Merger Agreement also provides that in the event the treatment, as set forth in (i)-(iv) above, of any LivePerson Options or LivePerson RSUs held by persons outside of the United States would be administratively burdensome to the Company, the Company may either cash out such equity awards or convert them into cash-based awards that continue to vest on the same schedule.

Subject to the terms and conditions of the Amended and Restated Merger Agreement, at the Second Effective Time, each share of LivePerson Common Stock that is held through the Tel-Aviv Stock Exchange Clearing House Ltd. (each, a “TASE Share”) and issued and outstanding immediately prior to the Second Effective Time (other than any Dissenting Shares (as defined below)) will be automatically converted into the right to receive an amount in cash equal to (a) the Closing TASE Cash Merger Consideration (as defined below), divided by (b) the total number of TASE Shares that are issued and outstanding as of immediately prior to the Second Effective Time (such number of shares, the “Fully Diluted TASE Common Number”, and the result of the calculation set forth in the foregoing clauses (a) and (b), the “Per Share Cash Merger Consideration”).

The aggregate amount of cash consideration payable by the Company to holders of TASE Shares (other than Dissenting Shares) in connection with the Second Merger pursuant to the terms of the Amended and Restated Merger Agreement will be an amount in cash equal to (a) the Closing Merger Consideration, multiplied by (b) the Company Closing VWAP Stock Price, multiplied by (c) a fraction, the numerator of which is the Fully Diluted TASE Common Number, and the denominator of which is the Fully Diluted Common Number (the “Closing TASE Cash Merger Consideration”); provided that, in the event such amount exceeds $7,500,000, “Closing TASE Cash Merger Consideration” will be $7,500,000.

Any TASE Shares that are issued and outstanding immediately prior to the Second Effective Time and held by a holder or beneficial owner who did not vote in favor of the adoption of the Amended and Restated Merger Agreement and properly demanded appraisal of such TASE Shares (“Dissenting Shares”) in accordance with Section 262 of the DGCL will not be converted into the right to receive the Per Share Cash Merger Consideration and will instead, at the Second Effective Time, be converted into the right to receive payment of the fair value of such Dissenting Shares in accordance with the terms of the Amended and Restated Merger Agreement.

It is expected that the Mergers will not qualify as a tax-free reorganization for U.S. federal income tax purposes.

Consistent with the Original Merger Agreement, under the terms of the Amended and Restated Merger Agreement, completion of the Mergers is subject to customary closing conditions, including, among others (a) the adoption of the Amended and Restated Merger Agreement by the stockholders of LivePerson; (b) the absence of any law, order or other legal impediment prohibiting the consummation of the Mergers; (c) the receipt of approvals under certain applicable foreign direct investment laws; (d) the approval for listing the shares of Company Common Stock issuable to the stockholders of LivePerson pursuant to the Amended and Restated Merger Agreement on the Nasdaq; (e) the effectiveness of the Company’s registration statement on Form S-4; (f) the accuracy of the parties’ respective representations and warranties in the Amended and Restated Merger Agreement, subject to specified materiality qualifications; (g) the performance or compliance by the Company and LivePerson with the covenants in the Amended and Restated Merger Agreement in all material respects; (h) the absence of a material adverse effect on LivePerson (as defined in the Amended and Restated Merger Agreement); and (i) the consummation of the Notes Restructuring Transactions (as in the Amended and Restated Merger Agreement).

Consistent with the Original Merger Agreement, the Amended and Restated Merger Agreement contains customary representations, warranties and covenants made by each of the Company, Merger Subs and LivePerson, including, among others, covenants by LivePerson regarding the conduct of its business during the pendency of the transactions contemplated by the Amended and Restated Merger Agreement, public disclosures and other matters. LivePerson is required, among other things, not to solicit alternative business combination transactions and, subject to certain exceptions, not to engage in discussions or negotiations regarding an alternative business combination transaction.

Consistent with the Original Merger Agreement, both the Company and LivePerson may terminate the Amended and Restated Merger Agreement under specified circumstances, including (a) if the Mergers are not completed by October 21, 2026 (which date may be extended to December 5, 2026 if certain regulatory approvals have not been obtained); (b) if LivePerson fails to obtain stockholder approval; (c) if the board of directors of LivePerson makes an adverse recommendation change with respect to the Mergers or commits a material breach of its non-solicitation obligations; (d) if the board of directors of LivePerson terminates to accept a superior acquisition proposal; or (e) if the Notes Restructuring Transactions are terminated for any reason. Consistent with the Original Merger Agreement, the Amended and Restated Merger Agreement further provides that LivePerson is required to pay the Company a termination fee of $5,000,000, plus the Company’s transaction expenses, if the Amended and Restated Merger Agreement is terminated under certain specified circumstances, including if the board of directors of LivePerson changes or withdraws its recommendation of the Mergers, terminates the Amended and Restated Merger Agreement to enter into an agreement with respect to a superior acquisition proposal or if the Notes Restructuring Transactions terminate for any reason or otherwise fail to consummate by the Outside Date (as defined in the Amended and Restated Merger Agreement), except where such termination or failure to consummate primarily resulted from the Company’s material breach of the Notes Restructuring Agreement (as defined in the Amended and Restated Merger Agreement); provided that where a termination fee is payable in connection with the failure to consummate, or termination of, the Note Restructuring Transactions, the obligation to reimburse the Company’s transaction expenses will be capped at $3,750,000.

Consistent with the Original Merger Agreement, the Amended and Restated Merger Agreement and the consummation of the transactions contemplated thereby, including the Mergers, have been unanimously approved by LivePerson’s board of directors, and LivePerson’s board of directors has resolved to recommend to the stockholders of LivePerson to adopt the Amended and Restated Merger Agreement, subject to its terms and conditions.

The Amended and Restated Merger Agreement is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The foregoing description does not purport to be complete and is subject to and qualified in its entirety by reference to the Amended and Restated Merger Agreement. The Amended and Restated Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Merger Subs or LivePerson. In particular, the assertions embodied in the representations and warranties contained in the Amended and Restated Merger Agreement are qualified by information in a confidential disclosure letter provided by LivePerson to the Company in connection with the signing of the Original Merger Agreement and in filings of the parties with the United States Securities and Exchange Commission (the “SEC”). The confidential disclosure letter contains information that modifies, qualifies and creates exceptions to the representations and warranties and certain covenants set forth in the Amended and Restated Merger Agreement. Moreover, the representations and warranties in the Amended and Restated Merger Agreement were used for the purposes of allocating risk between the Company and LivePerson rather than establishing matters of fact. Accordingly, the representations and warranties in the Amended and Restated Merger Agreement should not be relied on as characterization of the actual state of facts about the Company, Merger Subs or LivePerson.
