Every Voted Share Brings Transaction Closer to Completion

Urges Stockholders to Vote "FOR" SoundHound AI Transaction by September 1

NEW YORK, Aug. 25, 2026 /PRNewswire/ -- LivePerson (NASDAQ:LPSN) ("LivePerson" or "the Company") today urged stockholders who have not yet voted to submit their proxy immediately ahead of the September 1, 2026, 11:59 p.m. ET voting deadline. The Company issued the following statement:

Stockholders:

LivePerson is close to securing the stockholder approval needed to close the transaction, but every unvoted share has the same effect as voting against the transaction. The Special Meeting of Stockholders reconvenes in eight days, on Wednesday, September 2, 2026, and the window to have your voice counted is closing. As of August 20, 2026, over 97% of LivePerson shares casting votes have been in favor of the transaction.

We are close, but not there yet. Join ISS, Glass Lewis, and your fellow stockholders in voting "FOR" the transaction today. If LivePerson does not reach the votes needed, the merger will not be completed, LivePerson will remain a standalone company, and the Company will continue to face significant risks and debt. This could eventually lead to stockholders receiving no value for their LivePerson shares.

Voting takes less than two minutes. Cast your vote today online, by phone or by mail:

Online: www.proxyvote.com, or scan the QR code on your proxy card.
Phone: Call 1-800-690-6903 with your proxy card, or 1-800-322-2885 to speak with a proxy specialist.
Mail: Mark, sign, and date your proxy card and return it in the postage-paid envelope. Please note that mail may not arrive in time; online or phone voting is strongly recommended given the short window remaining.

VOTE TODAY

Stockholders of record as of the close of business on July 6, 2026, are entitled to vote at the Special Meeting. If you have already submitted your proxy, your vote remains valid and there is nothing further you need to do.

Many factors could cause actual future events to differ materially from the forward-looking statements in this communication, including: (1) the occurrence of any event, change, or other circumstance that could give rise to the right of one or both of the parties to terminate the definitive merger agreement between LivePerson and SoundHound; (2) the possibility that the transaction does not close when expected or at all due to the failure to satisfy all of the conditions to closing on a timely basis or at all, including the failure to obtain the required shareholder approvals or to consummate the notes restructuring transactions contemplated by the Notes Restructuring Agreement; (3) the risk that the benefits from the transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, trade policy (including tariff levels), laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which LivePerson and SoundHound operate; (4) any failure to promptly and effectively integrate the businesses of LivePerson and SoundHound; (5) the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; (6) reputational risk and potential adverse reactions of LivePerson's or SoundHound's customers, employees or other business partners, including those resulting from the announcement, pendency or completion of the transaction; (7) the diversion of management's attention and time to the transaction from ongoing business operations and opportunities; and (8) the outcome of any legal proceedings that may be instituted against LivePerson or SoundHound or in connection with the transaction. Further information on factors that could affect the forward-looking statements and expectations above are contained in the filings that LivePerson and/or SoundHound AI have filed, or that will be filed, with the U.S. Securities and Exchange Commission (the "SEC"), including as set forth in the Form S-4 and the proxy statement/prospectus contained therein, as well as the documents incorporated by reference therein.
