EXPLANATORY NOTE

As previously reported, LivePerson, Inc. (the “Company”) will hold a Special Meeting of Stockholders (the “Meeting”) on August 20, 2026, at 10:00 a.m. (Eastern Time), which will be held via a live audio webcast at www.virtualshareholdermeeting.com/LPSN2026SM. The Meeting was originally announced in the Company’s Proxy Statement/Prospectus filed with the Securities and Exchange Commission (the “SEC”) on July 9, 2026.

On August 11, 2026, the Company provided an adapted Hebrew version of the Company’s proxy card for use by stockholders holding shares of the Company traded on the Tel Aviv Stock Exchange. The English translation of the introductory message and proxy card are included below.

Special Meeting of Shareholders of LivePerson, Inc. (the “Company”)

Scheduled for August 20, 2026

Proxy Card / Voting Card

Following the Company’s reports dated April 22, 2026, July 10, 2026, and July 23, 2026 (the “Previous Reports” and the “Proxy Statement”, as applicable), in connection with the Company entering into a merger agreement dated July 2, 2026 (as amended or may be amended from time to time), with SoundHound AI, Inc. (“SoundHound”), Lightspeed Merger Sub Inc., an indirect wholly owned subsidiary of SoundHound, and Lightspeed Merger Sub II Inc., an indirect wholly owned subsidiary of SoundHound, and in connection with the convening of a special meeting of the Company’s shareholders for the purpose of approving the aforementioned merger transaction scheduled for August 20, 2026 at 10:00 a.m. (Eastern Time) (the “Meeting”), the Company is honored to attach below a proxy card regarding the Meeting in an adapted Hebrew version for the Company’s shareholders who hold their shares in the Company through members of the Tel Aviv Stock Exchange Clearing House (“TASE Holders” and “TASE Shares”, respectively).

Shareholders holding TASE Shares and who intend to vote their shares, are required to provide to the Company’s legal counsel (as noted below), an ownership certificate confirming their ownership of the TASE Shares on the record date for the Meeting. Such ownership certificate must be issued by a member of the Tel Aviv Stock Exchange, as required by the Companies Regulations (Proof of Ownership of a Share for the Purpose of Voting at a General Meeting), 5760-2000, as amended from time to time. Any such shareholder is entitled to receive the ownership certificate from the Tel Aviv Stock Exchange member where their account is managed, at the branch or by mail to the address of that shareholder (in exchange for delivery fees), upon request. Such a request should be submitted as soon as possible and must relate to the specific securities account of the TASE Holder where the relevant TASE Shares are held.

TASE Holders wishing to vote at the Meeting are required to fill out, sign, date, and email the attached Proxy Card in accordance with the instructions detailed therein, together with their ownership certificate (as stated above), to the Company’s Israeli legal counsel – Arnon, Tadmor-Levi law firm, from the Azrieli Center (Square Tower), Tel Aviv, Israel 6702101, to the attention of Adv. Moshe Pesker (email: MosheP@ArnonTL.com), no later than 7:00 p.m. (Israel time) on August 19, 2026 (the “Deadline”).

It is clarified that TASE Holders may also vote using the English version of the Proxy Card attached to the Company’s Proxy Statement, in accordance with the instructions specified in the Proxy Statement. In the event of a vote being submitted both via the Hebrew proxy card and the English Proxy Card, the valid later vote will be counted (provided it arrived no later than the Deadline).

Alternatively, TASE Holders may also vote electronically via the electronic voting system of the Israel Securities Authority (the “Electronic Voting System”), after receiving a personal identification number, access code, and additional information regarding the Meeting from the relevant TASE member through which the shares are held, and after completing a secure identification process, no later than six (6) hours before the time set for the Meeting. The Electronic Voting System is available at the following link: https://votes.isa.gov.il Where applicable, a shareholder may request instructions regarding such electronic voting from their TASE member. For the avoidance of doubt, if a shareholder voted using a proxy card and subsequently voted again via the Electronic Voting System, the later vote shall determine, provided that such later vote was submitted no later than the voting deadline noted above.

For further details and information regarding the merger transaction and the items on the agenda of the Meeting, see the Previous Reports (which are incorporated herein by reference).
