Eve Holding, Inc.

We are, from time to time, subject to various claims, lawsuits and other legal and administrative proceedings arising in the ordinary course of business. We are not currently a party to any such claims, lawsuits or proceedings, the outcome of which, if determined adversely to us, we believe would, individually or in the aggregate, be material to our business or result in a material adverse effect on our future operating results, financial condition or cash flows.

On March 3, 2025, a putative shareholder derivative action was filed in the Delaware Court of Chancery against EAH, our directors and certain of our officers, asserting breach of fiduciary duty claims related to the 2024 Private Placement of common stock and warrants that were issued to EAH in September 2024. Eve Holding was also named as a nominal defendant in the case. The action is captioned Taylor v. Embraer Aircraft Holding, Inc., et al., C.A. No. 2025-0233-NAC. The complaint seeks, among other things, declaratory relief, damages, costs and attorneys’ fees and expenses. Pursuant to the operative scheduling order, the defendants moved to dismiss the complaint on April 30, 2025.

On May 28, 2025, the plaintiff filed a motion to certify questions regarding the constitutionality of recent amendments to 8 Del. C. § 144, which related to certain arguments raised in the defendants’ respective motions to dismiss, to the Delaware Supreme Court. On June 20, 2025, the Court entered a joint stipulated order staying all proceedings pending the Delaware Supreme Court’s resolution of overlapping constitutional questions regarding the recent amendments to 8 Del. C. § 144 raised in another unrelated action, Rutledge v. Clearway Energy Group LLC, et al., C.A. No. 2025-0499-LWW. On February 27, 2026, the Delaware Supreme Court issued an opinion upholding the constitutionality of the recent amendments to 8 Del. C. § 144. Per the stipulated order staying all proceedings, the parties are expected to submit a proposed schedule to the Court for resuming proceedings in the action by March 24, 2026.

Based on the early stage of the case, we are unable to predict the ultimate outcome or estimate the range of possible loss, if any.
