Item 1.01 Entry into a Material Definitive Agreement.

The Merger Agreement

On April 21, 2026, LivePerson, Inc., a Delaware corporation (“LivePerson”), entered into a Merger Agreement (the “Merger Agreement”), by and among LivePerson, SoundHound AI, Inc., a Delaware corporation (“SoundHound”) and Lightspeed Merger Sub Inc., a Delaware corporation and an indirect wholly owned subsidiary of SoundHound (“Merger Sub”), pursuant to which, on the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into LivePerson (the “Merger”), with LivePerson surviving the Merger as an indirect wholly owned subsidiary of SoundHound. All capitalized terms used in this summary of the Merger Agreement that are not otherwise defined herein have the meanings ascribed to such terms in the Merger Agreement.

Subject to the terms and conditions of the Merger Agreement, at the date and time the Merger becomes effective (the “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 Effective Time (other than certain excluded shares) will be automatically converted into the right to receive a number of shares of Class A common stock of SoundHound, par value $0.0001 per share (“SoundHound 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 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”). It is intended that the Merger be treated as a transaction in which gain or loss is recognized for U.S. federal income tax purposes.

The aggregate amount of consideration payable by SoundHound to holders of LivePerson Common Stock in connection with the Merger pursuant to the terms of the Merger Agreement will be a number of shares of SoundHound Common Stock equal to the quotient of (a) the Aggregate Consideration Amount (as defined below), divided by (b) the SoundHound Closing Stock Price (the “Closing Merger Consideration”).

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 SoundHound and converted into an option to acquire shares of SoundHound Common Stock, in accordance with the terms of the Merger Agreement). “LivePerson Shortfall Cash” refers to an amount equal to (x) $74,000,000 (or, solely for purposes of the 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 of the Merger (the “Closing”) (the figure resulting from clause (x) minus clause (y), the “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 date on which the Closing occurs (the “Closing Date”) (net of certain LivePerson transaction expenses as of the Closing) (the foregoing clause (z), the “LivePerson Cash Balance”); provided that, if a negative number results from such calculation, “LivePerson Shortfall Cash” will be $0. The “SoundHound Closing Stock Price” refers to the price per share of SoundHound Common Stock derived from the average of the daily volume weighted average prices of a share of SoundHound 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; provided that, in the event such price per share (I) exceeds $12 per share, “SoundHound Closing Stock Price” will be $12 per share or (II) falls below $7 per share, “SoundHound Closing Stock Price” will be $7 per share.

The Merger Agreement provides that, at the 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 SoundHound Closing Stock Price (each, an “In-the-Money Option”) and held by any individual who is not an “employee” of SoundHound within the meaning of Form S-8 as of immediately after the 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 SoundHound and converted into corresponding awards denominated in shares of SoundHound Common Stock in accordance with the terms set forth in the Merger Agreement and (v) all warrants to purchase shares of LivePerson Common Stock will be cancelled for no consideration. The 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 SoundHound, SoundHound may either cash out such equity awards or convert them into cash-based awards that continue to vest on the same schedule.

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

The Merger Agreement contains customary representations, warranties and covenants made by each of SoundHound, Merger Sub and LivePerson, including, among others, covenants by LivePerson regarding the conduct of its business during the pendency of the transactions contemplated by the 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.

Both SoundHound and LivePerson may terminate the Merger Agreement under specified circumstances, including (a) if the Merger is 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 (the “LivePerson Board”) makes an adverse recommendation change with respect to the Merger or commits a material breach of its non-solicitation obligations; (d) if the LivePerson Board terminates to accept a superior acquisition proposal; or (e) if the Notes Restructuring Transactions are terminated for any reason. The Merger Agreement further provides that LivePerson is required to pay SoundHound a termination fee of $5,000,000, plus SoundHound’s transaction expenses, if the Merger Agreement is terminated under certain specified circumstances, including if the LivePerson Board changes or withdraws its recommendation of the Merger, terminates the 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 Merger Agreement), except where such termination or failure to consummate primarily resulted from SoundHound’s material breach of the Notes Restructuring 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 SoundHound’s transaction expenses will be capped at $3,750,000.

The Merger Agreement and the consummation of the transactions contemplated thereby, including the Merger (collectively, the “Transactions”) have been unanimously approved by the LivePerson Board, and the LivePerson Board has resolved to recommend to the stockholders of LivePerson to adopt the Merger Agreement, subject to its terms and conditions.

The 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 Merger Agreement. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about SoundHound, Merger Sub or LivePerson. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement are qualified by information in a confidential disclosure letter provided by LivePerson to SoundHound in connection with the signing of the 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 Merger Agreement. Moreover, the representations and warranties in the Merger Agreement were used for the purposes of allocating risk between SoundHound and LivePerson rather than establishing matters of fact. Accordingly, the representations and warranties in the Merger Agreement should not be relied on as characterization of the actual state of facts about SoundHound, Merger Sub or LivePerson.

The Notes Restructuring Agreement

On April 21, 2026, concurrently with the execution and delivery of the Merger Agreement, SoundHound entered into a Notes Restructuring Agreement (the “Notes Restructuring Agreement”) with LivePerson and each of the holders of LivePerson’s First Lien Convertible Secured Notes due 2029 (the “First Lien Secured Notes”) and LivePerson’s Second Lien Senior Subordinated Secured Notes due 2029 (the “Second Lien Secured Notes” and, together with the First Lien Secured Notes, the “Secured Notes”), pursuant to which and on the terms and subject to the conditions thereof, among other things, the holders of the Secured Notes have agreed to release and deem satisfied the Secured Notes for the consideration contemplated thereby (the transactions contemplated by the Notes Restructuring Agreement, “Notes Restructuring Transactions”).

Upon consummation of the Notes Restructuring Transactions, on the terms and subject to the conditions set forth in the Notes Restructuring Agreement, each holder of First Lien Secured Notes has agreed to accept, in full and complete satisfaction of all obligations of LivePerson to such holder, (a) a number of shares of SoundHound Common Stock equal to the quotient of (i) $178,007,733.68 (the “First Lien Holder Aggregate Consideration Amount”), divided by (ii) the SoundHound Closing Stock Price and (b) an amount in cash paid by LivePerson concurrently with Closing in the amount of (i) accrued and unpaid interest on the First Lien Secured Notes held by such holder, plus (ii) 65% of any LivePerson Excess Cash.

Upon consummation of the Notes Restructuring Transactions, on the terms and subject to the conditions set forth in the Notes Restructuring Agreement, each holder of Second Lien Secured Notes has agreed to accept, in full and complete satisfaction of all obligations of LivePerson to such holder, such holder’s pro rata portion of (a) a number of shares of SoundHound Common Stock equal to the quotient of (i) $83,207,733.68 (the “Second Lien Holder Aggregate Consideration Amount”), divided by (ii) the SoundHound Closing Stock Price and (b) an amount in cash equal to (i) the principal amount of any 2026 Convertible Notes repurchased and retired by LivePerson between April 1, 2026 and the Closing, minus (ii) the amount of cash paid to repurchase such 2026 Convertible Notes, plus (iii) 35% of LivePerson Excess Cash.

“LivePerson Excess Cash” refers to the difference of (a) the LivePerson Cash Balance, minus (b) the LivePerson Minimum Cash; provided that, if a negative number results from such calculation, “LivePerson Excess Cash” shall be $0.

The shares of SoundHound Common Stock to be issued in connection with the Notes Restructuring Transactions are expected to be issued in reliance on the exemption from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”).

The Notes Restructuring Agreement provides SoundHound the option to elect, at any time before the close of business two business days prior to the Closing Date, to substitute an amount of cash in lieu of all or a portion of the stock consideration paid to the holders of Secured Notes, provided that (a) each holder of Secured Notes receives the same proportion of its consideration in cash and shares of SoundHound Common Stock; (b) regardless of the SoundHound Closing Stock Price, the proportion of consideration satisfied in cash shall be calculated assuming the stock consideration is worth the First Lien Holder Aggregate Consideration Amount and the Second Lien Holder Aggregate Consideration Amount, respectively and (c) in the event SoundHound Closing Stock Price is greater than $12 per share, SoundHound shall not be entitled to substitute cash for more than 50% of the stock consideration.

Under the terms of the Notes Restructuring Agreement, completion of the Notes Restructuring Transactions is subject to customary closing conditions, including (a) the absence of any order or other legal impediment prohibiting the consummation of the Notes Restructuring Transactions; (b) the closing conditions under the Merger Agreement being satisfied or waived (other than the consummation of the Notes Restructuring Transactions); (c) the requisite securities law filings having been made; (d) the approval for listing the shares of SoundHound Common Stock issuable to the holder of the Secured Notes pursuant to the Notes Restructuring Agreement on the Nasdaq; (e) the accuracy of the parties’ respective representations and warranties in the Notes Restructuring Agreement, subject to specified materiality qualifications; (f) the performance or compliance by SoundHound, LivePerson and the holders of Secured Notes with the covenants in the Notes Restructuring Agreement in all material respects; (g) the delivery of all required payments under the Notes Restructuring Agreement; (h) the entry into a registration rights agreement in respect of the shares of SoundHound Common Stock issuable to the holders of the Secured Notes; and (i) the substantially contemporaneous consummation of the Notes Restructuring Transactions by the holders of the First Lien Secured Notes and the holders of the Second Lien Secured Notes.

The Notes Restructuring Agreement contains customary representations, warranties and covenants made by each of the parties, including, among others, that the shares of SoundHound Common Stock issued in connection with the Notes Restructuring Transactions will be eligible for resale pursuant to an effective registration statement filed by SoundHound with the SEC. The holders of Secured Notes are required, among other things, not to solicit alternative business combination or note restructuring transactions and not to engage in discussions or negotiations regarding an alternative business combination or note restructuring transaction.

The Notes Restructuring Agreement automatically terminates upon any termination of the Merger Agreement in accordance with its terms. Additionally, each of the parties may terminate the Notes Restructuring Agreement under specified circumstances, including if the Notes Restructuring Transactions are not completed on or prior to the fifth business day following the Outside Date (as defined in the Merger Agreement). The holders of the First Lien Secured Notes are entitled to terminate the Notes Restructuring Agreement upon (a) any failure by LivePerson to pay amounts due under the indenture or other agreements governing the First Lien Secured Notes or (b) a breach of certain provisions of the indenture governing the First Lien Secured Notes, in each case, subject to cure rights of LivePerson and SoundHound.

The Notes Restructuring Agreement is attached hereto as Exhibit 10.1 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 Notes Restructuring Agreement.

Item 5.03

Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On April 21, 2026, prior to the execution of the Merger Agreement, the LivePerson Board adopted an amendment to LivePerson’s Fourth Amended and Restated By-Laws (the “By-Laws Amendment”). The By-Laws Amendment adds a new Article X, which provides that, unless LivePerson otherwise consents to an alternative forum in writing, (i) the Court of Chancery of the State of Delaware is designated as the sole and exclusive forum for certain specified legal actions involving LivePerson and (ii) the federal district courts of the United States of America, to the fullest extent permitted by law, are designated as the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended.

The foregoing description of the By-Laws Amendment is qualified in its entirety by the full text of the By-Laws Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated by reference herein.

Item 7.01

On April 21, 2026, LivePerson and SoundHound issued a joint press release announcing execution of the Merger Agreement and the Notes Restructuring Agreement. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Forward-looking statements are based on the estimates and opinions of management at the time the statements are made. Neither SoundHound nor LivePerson undertakes any obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof.
