LivePerson Reminds Stockholders of Additional Time to Vote FOR SoundHound AI Transaction

LivePerson (NASDAQ: LPSN) has issued a formal letter reminding stockholders of the new deadline to cast their vote "FOR" the proposed transaction with SoundHound AI, Inc. (NASDAQ: SOUN). Stockholders are encouraged to vote ahead of the Special Meeting on September 2, 2026. The letter, filed with the U.S. Securities and Exchange Commission, is available at www.VoteLivePerson.com.

The Special Meeting of Stockholders of LivePerson, Inc. has been adjourned to Wednesday, September 2, 2026, at 10:00 a.m. ET. The new deadline to submit votes online or by telephone is Tuesday, September 1, 2026, at 11:59 p.m. ET. Votes cast to date are over 97% in favor of the transaction, but a majority of all outstanding shares is required for completion. LivePerson urges stockholders to vote as soon as possible to realize the benefits of the transaction and protect their investment.

By voting "FOR" the transaction with SoundHound AI, stockholders will receive shares of SoundHound stock valued at approximately $3.33 per share of LivePerson common stock as of the April 21, 2026 announcement, representing an approximate 22% premium over the 30-day volume-weighted average price before the announcement. Failure to vote has the same effect as voting "AGAINST" the merger, which could lead to LivePerson operating as a standalone company facing numerous risks, potentially resulting in a reorganization or restructuring where stockholders receive no value for their shares.

Stockholders can vote online at www.proxyvote.com, by phone by calling 1-800-690-6903, or by mail by returning their signed proxy card. Votes must be received by 11:59 p.m. Eastern Time on September 1, 2026. Alternatively, stockholders can attend the meeting via the Internet and vote during the meeting at www.virtualshareholdermeeting.com/LPSN2026SM if their shares are held directly. Even if planning to attend, voting today is recommended. Those holding shares through a bank or broker should follow their instructions. Separate instructions are provided for shares held on the Tel Aviv Stock Exchange.
