“Disclosure pursuant to Section 13(r) of the Securities Exchange Act of 1934. Funds affiliated with Blackstone first invested in Atlantia S.p.A. on November 18, 2022 in connection with the voluntary public tender offer by Schema Alfa S.p.A. for all of the shares of Atlantia S.p.A., pursuant to which such funds obtained a minority non-controlling interest in Atlantia S.p.A. Atlantia S.p.A. owns and controls Aeroporti di Roma S.p.A. (“ADR”), an operator of airports in Italy including Leonardo da Vinci-Fiumicino Airport. Iran Air has historically operated periodic flights to and from Leonardo da Vinci-Fiumicino Airport as authorized, from time to time, by an aviation-related bilateral agreement between Italy and Iran, scheduled in compliance with European Regulation 95/93, and approved by the Italian Civil Aviation Authority. ADR, as airport operator, is under a mandatory obligation to provide airport services to all air carriers (including Iran Air) authorized by the applicable Italian authority. The relevant turnover attributable to these activities (whose consideration is calculated on the basis of general tariffs determined by such independent Italian authority) in the quarter ended December 31, 2022 was less than €30,000. Atlantia S.p.A. does not track profits specifically attributable to these activities.”
