• Effective April 1, 2026, Yasuhiko Hashimoto was appointed to the Board and will serve on the Audit and Compensation Committees. Mr. Hashimoto was nominated by Mizuho Leasing Company Limited and was appointed under the Company’s Bye-Laws.

Key Details

• Effective date: April 1, 2026 (resignation and appointment).
• Outgoing director: Keiji Okuno — Board member since September 2022; Audit and Investment Committees.
• Incoming director: Yasuhiko Hashimoto — nominated by Mizuho Leasing; will serve on Audit and Compensation Committees.
• Background on Hashimoto: Managing Executive Officer at Mizuho Leasing; >30 years at Mizuho Bank with senior roles in global corporate and structured finance; holds an MBA from NYU Stern and a Bachelor of Law from the University of Osaka.
• Compensation: Mr. Hashimoto will not receive any compensation from Aircastle for his service as a director.

Why It Matters

• Board composition and committee memberships affect corporate oversight of finance, audits and executive pay. The change swaps a director with Audit and Investment committee responsibilities for a director who will sit on Audit and Compensation, which may shift committee experience and voting dynamics.
• Hashimoto’s nomination by Mizuho Leasing and his long finance/banking background signals continued influence from that investor/partner and brings experience in structured finance and global transportation assets—relevant to Aircastle’s aircraft leasing business. The filing is a routine governance disclosure with no financial amounts reported.
