Incorporated in 2021 and headquartered in Wilmington, Delaware, at 2810 N. Church Street, Suite 94644, the company completed a $100 million initial public offering of 10 million units in February 2022, each consisting of one Class A ordinary share and one-half of a warrant exercisable at $11.50, with shares and warrants trading under SGHL and SGHLW, respectively, prior to delisting. In May 2023, unable to complete an initial business combination within its required timeframe despite pursuing numerous opportunities, Signal Hill announced its intention to dissolve and liquidate, redeeming all outstanding public shares at approximately $10.43 per share from its trust account, cancelling shares effective May 26, 2023, and terminating its NASDAQ listing via Form 25 with warrants expiring worthless; the redemption process concluded by May 29, 2023, marking the company's defunct status with no subsequent operations, mergers, or strategic changes reported.
