Shareholder rights law firm Robbins LLP informs investors that a class action was filed on behalf of all persons and entities who purchased or otherwise acquired AEVEX Corp. (NYSE: AVEX) Class A common stock (a) between April 17, 2026 and June 4, 2026, and (b) pursuant to the Company’s initial public offering (“IPO”) on April 17, 2026 (the “Class Period”). AEVEX is a military technology contractor.

The complaint alleges that AEVEX concealed a pre-arranged plan between Madison, which owned 100% of AEVEX’s common stock, and the Underwriter Defendants to prematurely override the commitment requiring a 180-day lock-up after the IPO to prevent Madison from selling its shares.

Investors who suffered significant losses during the Class Period may be eligible to participate in the lawsuit and should contact Robbins LLP for information.

What Was AEVEX’s Path to its IPO?

Madison is a Chicago, IL-based private equity firm. Immediately prior to the IPO, Madison owned 100% of AEVEX’s common stock, and after completion of the IPO, Madison continued to own 77.5% of AEVEX’s common stock. According to the IPO Offering Documents, AEVEX is “a controlled company” by virtue of Madison’s outsized ownership of AEVEX’s common stock.

Why Was AEVEX Sued?

The complaint alleges that AEVEX made materially false or misleading statements regarding its business, operations, and financial condition during the Class Period.

Specifically, the lawsuit alleges that the AEVEX failed to disclose that the Company conveyed a commitment to follow a 180-day “lock-up” and therefore prevent Madison from selling its Class A common stock or converting or exchanging its Class B or LLC Units into Class A common stock for public sale until at least October 13, 2026, while simultaneously concealing a pre-arranged plan between Madison and the Underwriter Defendants to prematurely abrogate that commitment and allow for an SPO shortly after the IPO. Plaintiff alleges that through that SPO, Madison would earn over $200 million and the Underwriter Defendants would share in a further $8-plus million in fees.

Why Did AEVEX’s Stock Drop?

The complaint alleges after the market closed on June 1, 2026, defendants filed a registration statement with the SEC on Form S-1 announcing the Company’s intention to sell eight million more shares of Class A common stock to the investing public via an SPO. On June 3, defendants sold eight million shares at $27.00 per share through the same underwriters involved in the IPO.

Of the eight million Class A common stock sold in the SPO, 2,273,843 shares would be sold from Madison’s Class A holdings, while the other 5,726,157 Class A shares sold in the offering would be newly issued shares, the proceeds of which AEVEX would use to purchase an equivalent number of Madison’s other holdings in AEVEX earned zero from the SPO, while the Underwriter Defendants shared in over $8 million more in fees.

In reaction to the after-market filing of the June 1, 2026 registration statement, on June 2, 2026, AEVEX’s Class A common stock fell approximately 16% against the prior day’s closing price, wiping out over $700 million in market capitalization. And in response to the pre-market filing of the final prospectus on June 5, 2026, AEVEX’s common stock fell a further 7% that day, erasing about $200 million more in market capitalization.

Who Can Participate in the AEVEX Case?

The lawsuit seeks to represent investors who purchased or otherwise acquired AEVEX Class A common stock:

(a) between April 17, 2026 and June 4, 2026, and

(b) pursuant to the Company’s initial public offering (“IPO”) on April 17, 2026

Investors who suffered losses during that period may have legal rights under the federal securities laws.
