Executive Accountability: Douglas R. Ostermann Named in Securities Action

NEW YORK, May 28, 2026 /PRNewswire/ -- SueWallSt notifies investors that Douglas R. Ostermann, former Chief Financial Officer of Stellantis N.V. (NYSE: STLA), is named as a defendant in a securities class action covering purchases between February 26, 2025, and February 5, 2026. Find out if you qualify to recover losses from this action.

Shares fell $2.26 per share on February 6, 2026, a single-day decline of approximately 23.69%, after Stellantis disclosed €22 billion in charges and confirmed a shortfall against previously guided earnings benchmarks.

Ostermann's Role During the Class Period

As CFO, Ostermann was the senior financial officer responsible for Stellantis' public earnings guidance, quarterly reporting, and investor communications from the start of the Class Period through his departure on September 29, 2025. The complaint identifies Ostermann as the executive who, on February 26, 2025, told investors that North American margins would reach "mid- to high single-digit range" in the back half of 2025 and that Stellantis had "significant opportunities" on the cost side. By the time of the July 21, 2025 preliminary earnings call, Ostermann disclosed that first-half adjusted operating income had fallen to approximately €540 million, with an AOI margin of just 0.7%, while simultaneously revealing €3.3 billion in net charges excluded from those figures.

What Ostermann Allegedly Oversaw

The securities action alleges that during Ostermann's tenure as CFO:

• He guided investors toward "low single digit" first-half margins ramping to "mid- to high single-digit" in H2, while the Company was not positioned to achieve those benchmarks
• He characterized first-quarter results as reflecting "early, initial progress on our commercial recovery" even as net revenues declined 14% year-over-year
• He oversaw the suspension of full-year financial guidance on April 30, 2025, attributing it solely to "tariff-related uncertainties" rather than disclosing deeper structural problems
• He presided over the July 2025 disclosure of €2 billion in charges for cancelled programs, including €700 million for hydrogen fuel cell EV efforts and Maserati platform impairments
• He signed and certified SEC filings containing the allegedly misleading financial statements and projections

Ostermann's Certifications and Liability

Under Sarbanes-Oxley Sections 302 and 906, Ostermann personally certified that Stellantis' periodic filings with the SEC fairly presented the Company's financial condition. The complaint contends these certifications were made while Ostermann knew or should have known that Stellantis was not equipped to achieve its guided AOI benchmarks and that the pace of electrification adoption had been overestimated. Section 20(a) of the Securities Exchange Act imposes liability on individuals who exercised control over a company's operations and public statements.

"Individual officers who sign SEC certifications bear personal responsibility for the accuracy of corporate disclosures. When a CFO provides specific margin guidance to the investing public, investors are entitled to rely on those projections being grounded in reality," stated Joseph E. Levi, Esq.
