Official reason

Nader Khoon Siavash (Siavash) is the Director of AIO, the U.S. designated organization that oversees Iran’s ballistic missile programs. In his role as AIO Director, Siavash oversees AIO’s ballistic missile production and testing and deals with international suppliers. AIO was sanctioned under E.O. 13382 on June 28, 2005. Iran’s Central Bank has siphoned millions in discounted foreign currency — ostensibly earmarked for importers of essential goods — to AIO per year, underscoring the regime’s prioritization of its missile programs at the expense of its own citizens. Siavash is being designated pursuant to E.O. 13382 for acting or purporting to act for or on behalf of, directly or indirectly, AIO.
