CERTIFICATE OF AMENDMENT

TO THE

CERTIFICATE OF INCORPORATION

OF

WILLIS LEASE FINANCE CORPORATION

July 17, 2026

Willis Lease Finance Corporation (the “Corporation”), a corporation organized and existing under and by virtue of the provisions of the General Corporation Law of the State of Delaware (the “General Corporation Law”), hereby certifies that:

“ARTICLE IV

AUTHORIZED CAPITAL STOCK

(a) The corporation shall be authorized to issue two classes of shares of stock to be designated, respectively, “Preferred Stock” and “Common Stock”; the total number of shares which the corporation shall have authority to issue is Seventy-Five Million (75,000,000); the total number of shares of Preferred Stock shall be Fifteen Million (15,000,000) and each such share shall have a par value of one cent ($0.01); and the total number of shares of Common Stock shall be Sixty Million (60,000,000) and each such share shall have a par value of one cent ($0.01).

(b) The shares of Preferred Stock may be issued from time to time in one or more series. The board of directors is hereby vested with authority to fix by resolution or resolutions the designations and the powers, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation the dividend rate, conversion or exchange rights, redemption price and liquidation preference, of any series of shares of Preferred Stock, and to fix the number of shares constituting any such series, and to increase or decrease the number of shares of any such series (but not below the number of shares thereof then outstanding). In case the number of shares of any such series shall be so decreased, the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution or resolutions originally fixing the number of shares of such series.

(c) Upon the effectiveness (the “Effective Time”) of the Certificate of Amendment adding this clause (c) of this Article IV, each outstanding share of Common Stock and each share of Common Stock held as treasury stock immediately prior to the Effective Time shall, automatically and without any further action by the corporation or the stockholder thereof, be subdivided and reclassified into three (3) validly issued, fully paid and non-assessable shares of Common Stock, reflecting a three (3) for one (1) forward stock split (the “Forward Stock Split”). The par value per share of Common Stock shall remain one cent ($0.01). Each certificate that immediately prior to the Effective Time represented shares of Common Stock (“Old Certificates”) shall thereafter represent that number of shares of Common Stock into which the shares of Common Stock represented by the Old Certificate shall have been subdivided and reclassified, pursuant to the Forward Stock Split, until such certificate is surrendered to the Corporation for cancellation or exchange.”
