SoundHound AI Inc ( SOUN ) shares are falling Tuesday after the company announced it’s unable to timely file its 10-K with the U.S. Securities and Exchange Commission.

What Happened: SoundHound AI ( SOUN ) said in a regulatory filing early Tuesday that it requires additional time to prepare the financial statements for its annual 10-K for fiscal year ended Dec. 31, 2024, due to the complexity of accounting for recent acquisitions.
