forward-looking statements regulatory

"This communication contains “forward-looking statements” within the meaning of the U.S. federal securities laws"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

registration statement on Form S-4 regulatory

"SoundHound AI has filed with the U.S. Securities and Exchange Commission a registration statement on Form S-4"

A registration statement on Form S-4 is a formal filing with the U.S. Securities and Exchange Commission used when a company issues shares or other securities as part of a merger, acquisition, exchange offer or similar corporate deal. It bundles the transaction terms, financial statements, risk factors and shareholder vote materials so investors can assess the deal; think of it as a detailed prospectus or buyer’s packet that explains what you would own and how the deal could change your stake.

proxy statement/prospectus regulatory

"includes a definitive proxy statement of LivePerson and that constitutes a prospectus of SoundHound AI"

A proxy statement or prospectus is a document that companies send to shareholders to provide important information about upcoming decisions or investments, such as voting on company issues or offering new shares to the public. It helps investors understand the details and risks involved, enabling them to make informed choices about their ownership or involvement with the company.

Notes Restructuring Agreement financial

"to consummate the notes restructuring transactions contemplated by the Notes Restructuring Agreement"

participants in the solicitation regulatory

"SoundHound, LivePerson and their respective directors and executive officers may be deemed to be participants in the solicitation"

People or firms who actively seek to influence shareholders’ choices in a corporate action—such as a vote, merger, proxy contest, or tender offer. This can include company insiders, advisers, bankers, lawyers and professional solicitors who contact investors to persuade them. Investors care because knowing who is doing the persuading reveals potential conflicts, resources and credibility behind the campaign, much like checking who is organizing a political campaign before accepting its message.
