HYLN Investor Alert: Hyliion Holdings Corp. Securities Class Action Notice - Contact Levi & Korsinsky

NEW YORK, Oct. 19, 2026 (GLOBE NEWSWIRE) -- Levi & Korsinsky, LLP notifies investors in Hyliion Holdings Corp. (NYSE: HYLN) that a securities class action has been filed on behalf of shareholders who purchased securities between May 12, 2026 and June 23, 2026. Find out if you may be eligible to recover losses. You may also contact Joseph E. Levi, Esq. at jlevi@levikorsinsky.com or (212) 363-7500.

HYLN closed at $7.37 per share on June 22, 2026 and at $4.92 per share on June 24, 2026, a two-day decline of $2.45 per share, or 33.24%. Approximately $133 million of the Company's disclosed $400 million potential pipeline was tied to one non-binding letter of intent. The lead plaintiff deadline is October 27, 2026.

What the Company Disclosed

Hyliion's first quarter 2026 disclosures stated that the Company and VFG Holdings, LLC had entered a non-binding letter of intent to pursue deployment of up to 250 KARNO Cores, or approximately 50 megawatts, over the next five years, and described VFG as a developer of turnkey data center solutions including power infrastructure, compute systems, site development, and financing. Management told investors that signed non-binding letters of intent represented "a potential of about $400 million of revenue at today's current pricing." Disclosure language indicated only that the arrangement remained subject to execution of a definitive purchase agreement.

Disclosure Gaps Alleged

• No disclosure of when the counterparty was formed. The complaint states VFG was incorporated on January 5, 2026, roughly four months before the announcement.
• No disclosure of the counterparty's headcount, described in a June 23, 2026 research report as four employees.
• No disclosure of VFG's funding history or capital resources; the report cited an absence of publicly available funding data.
• No disclosure of what evaluation, if any, was performed regarding VFG's ability to finance and develop a proposed $133 million deployment.
• No quantification for investors of how much of the $400 million pipeline figure rested on the single VFG letter of intent.

Why Pipeline Specificity Allegedly Mattered

The complaint challenges the adequacy of a pipeline figure calculated by applying current pricing to non-binding letters of intent, arguing that the presentation gave investors a revenue anchor without the counterparty information needed to weigh its reliability. Plaintiffs also point to the Company's August 12, 2026 disclosure, after the Class Period, that revenue guidance was raised by 50% from $10 million to about $15 million while management acknowledged that most customer interest was "not yet reflected in LOIs or purchase contracts."

"Generic descriptions of a counterparty's capabilities cannot substitute for disclosing what a company actually knew, or did not know, about that counterparty's ability to perform. Here the allegations concern a letter of intent that reportedly accounted for roughly one-third of a disclosed pipeline." -- Joseph E. Levi, Esq.
