Company Description
Archimedes Tech SPAC Partners III Co. is a Cayman Islands blank-check company whose Nasdaq-listed units trade under the symbol ARCIU. The company is organized as a special purpose acquisition company, or SPAC, rather than as an operating business with products or service revenue. Its corporate purpose is to use capital raised from public and private securities offerings to pursue a business combination, subject to the capital-structure, trust-account, redemption, shareholder-vote and governance mechanics that apply to SPAC issuers.
The company's public security structure includes units, ordinary shares and warrants. Each ARCIU unit consists of one ordinary share, par value $0.0001 per share, and one-fourth of one redeemable warrant. The ordinary shares are registered under the symbol ARCI, and the warrants are registered under the symbol ARCIW. The company has disclosed that the ordinary shares and warrants included in the units may trade separately, while unseparated units continue to trade as units.
Archimedes Tech SPAC Partners III Co. completed an initial public offering of units and a concurrent private placement of private units. Proceeds from the public offering and private placement were deposited into a trust account established for the benefit of public shareholders. The sponsor identified in the filing record is Archimedes Tech SPAC Sponsors III LLC, and BTIG, LLC participated in the private placement as the representative of the underwriters in the initial public offering.
As a SPAC, the company's disclosures focus on security structure, trust-account funding, redemption mechanics, shareholder voting matters, sponsor economics, Nasdaq-listed securities and board or officer governance events. The company is incorporated in the Cayman Islands and lists Claymont, Delaware as its U.S. office location. It also reports emerging growth company status under U.S. securities regulations.
