Item 8.01 Other Events

As previously disclosed, 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 LivePerson, Inc., a Delaware corporation (“LivePerson”), entered into an Amended and Restated Merger Agreement, pursuant to which, on the terms and subject to the conditions set forth therein, 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.

As previously disclosed, the closing of the Mergers is conditioned upon, among other things, the receipt of foreign investment approvals in Bulgaria, Canada, Italy, Germany and the United Kingdom. Clearance was received from (I) the relevant Italian and Canadian regulatory authorities on June 25, 2026, (II) the relevant German regulatory authority on June 29, 2026 and (III) the relevant United Kingdom regulatory authority on July 1, 2026. On July 20, 2026, the final foreign investment clearance was received by the relevant Bulgarian authority.

The receipt of the foregoing foreign investment approvals satisfies all regulatory approval conditions to the closing of the Mergers. The Mergers remain subject to other closing conditions, including LivePerson stockholder approval, after which the Mergers will be consummated.

Such forward-looking statements are based upon management’s current expectations and include known and unknown risks, uncertainties and other factors, many of which the Company and LivePerson are unable to predict or control, that may cause actual results, performance or plans to differ materially from any future results, performance or plans expressed or implied by such forward-looking statements. These statements involve risks and uncertainties that could cause actual results to differ materially from those anticipated in these statements as a result of a number of factors, including, but not limited to: (a) the risk that the transactions described herein will not be completed or will not provide the expected benefits; (b) the failure to timely or at all obtain LivePerson stockholder approval for the Mergers; (c) the timing of obtaining such approvals and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transactions; (d) the risk that a condition to closing of the proposed transactions may not be satisfied on a timely basis or at all; (e) the possible occurrence of an event, change or other circumstance that would give rise to the termination of the Amended and Restated Merger Agreement; (f) the risk of stockholder litigation in connection with the Mergers, including resulting expense or delay in closing of the proposed transactions; (g) the failure of the proposed transactions to close for any other reason; (h) the diversion of the attention of the Company and LivePerson management from ongoing business operations; (i) unexpected costs, liabilities, charges or expenses resulting from the proposed transactions; (j) the risk that the integration of the Company and LivePerson will be more difficult, time-consuming or expensive than anticipated; (k) the risk of customer loss or other business disruption in connection with the proposed transactions, or of the loss of key employees; (l) the fact that unforeseen liabilities of the Company or LivePerson may exist; (m) changes in applicable laws or regulations and extensive and evolving government regulations that impact the Company’s or LivePerson’s operations and business; (n) investigations, claims, disputes, enforcement actions, litigation and/or other regulatory or legal proceedings, including with respect to AI technology; (o) risks that the Company may not be able to manage strains associated with its growth; (p) dependence on key personnel; (q) stock price volatility; (r) the Company’s and LivePerson’s ability to protect their intellectual property and litigation risks; (s) the risk that LivePerson’s usage patterns, customer renewals, customer outcomes and similar metrics differ from expectations; (t) the risk of cybersecurity incidents or breaches impacting LivePerson’s business; (u) the risks related to the use and regulation of artificial intelligence and machine learning; (v) general economic, financial, legal, political and business conditions; and (w) other risks inherent in the Company’s and LivePerson’s businesses.

All such factors are difficult to predict, are beyond the Company’s and LivePerson’s control, and are subject to additional risks and uncertainties, including those detailed in the Company’s annual report on Form 10-K for the year ended December 31, 2025 and those detailed in LivePerson’s annual report on Form 10-K for the year ended December 31, 2025 and LivePerson’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2026.
