Nasdaq halted trading in Eve Holding, Inc. Warrants (EVEX.W) on October 21, 2026, at 4:06:44.951 PM ET. The exchange issued halt code H11, which signifies a "regulatory concern". Trading halts with an H11 code can also occur when Nasdaq honors a halt initiated on another exchange for a dually listed security.

The specific nature of the regulatory concern that led to this trading halt has not been publicly disclosed in the available information.

Eve Holding, Inc. is identified as a U.S. company within the Industrials sector. Johann Christian Jean Charles Bordais is listed as its CEO. As of August 4, 2026, SEC filings indicated that Eve Holding, Inc. common stock (EVEX) and its warrants (EVEX-WT) were on the New York Stock Exchange (NYSE). The company's Exchange Act registration was revoked by August 4, 2026. Its registration as a Municipal Advisor was also revoked and cancelled. The Nasdaq halt of EVEX.W, while SEC filings from August 2026 show warrants on NYSE, suggests a potential dual listing or a change in listing status for the warrants.

In September 2022, law firm Pomerantz LLP announced an investigation into Eve Holding, Inc.. This investigation concerned whether the company and its officers or directors had engaged in securities fraud or other unlawful business practices. This followed a September 29, 2022, disclosure by Eve Holding, Inc. that its condensed consolidated financial statements for the quarter ended June 30, 2022, should not be relied upon. The company had reviewed its accounting for warrants to acquire 24,200,000 shares of common stock, which were issued and became exercisable on May 9, 2022. It expected to recognize certain non-cash expenses related to these warrants for the second quarter of 2022.

It remains unclear if the current trading halt is connected to these prior regulatory and accounting issues or if it stems from new developments.
