Navios Maritime Acquisition Corporation, which traded on the New York Stock Exchange under the ticker NNA, is a blank-check company that completed its initial public offering in 2008 with a focus on the maritime transportation sector, specifically the acquisition and operation of crude oil and petroleum product tanker vessels. The SPAC was sponsored by affiliates of Navios Maritime Holdings Inc., the broader Navios group helmed by Executive Chairman Angeliki Frangou. The company completed its business combination and transitioned into an operating tanker shipping enterprise, subsequently filing periodic reports as a foreign private issuer via Form 6-K. NNA was later absorbed into a broader Navios restructuring and is no longer independently listed.
