Allegations

According to the complaint, defendants provided overwhelmingly positive statements to investors while, at the same time, disseminating materially false and misleading statements and/or omitting material facts concerning the credibility of its announced commercial pipeline, notably, the basis for management’s confidence in its VFG Holdings (“VFG”) partnership and the extent of the Company’s evaluation of VFG’s operational capabilities, financial resources, and ability to perform before announcing the “new data center partnership” as a significant commercial opportunity. On June 23, 2026, Pelican Way Research issued a research report questioning the commercial viability of Hyliion’s announced partnership with VFG. Specifically, the report raised numerous red flags regarding VFG’s operational capabilities, financial resources, and development experience necessary to execute the approximately $133 million proposed transaction. On this news, the price of Hyliion’s common stock declined from a closing market price of $7.37 per share on June 22, 2026, to $6.10 per share on June 23, 2026, a decline of about 17%. The stock price continued to decline another 19% to $4.92 per share on June 24, 2026, as the market continued to absorb the news.

Lead Plaintiff Deadline

If you suffered a loss in Hyliion during the relevant time frame or pursuant to the relevant offering(s), you have until October 27, 2026 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn't require that you serve as a lead plaintiff.

Introduction

A securities class action lawsuit has been filed against Hyliion Holdings Corp. on behalf of investors who purchased or otherwise acquired Hyliion common stock during the class period. The lawsuit covers investors who purchased Hyliion common stock from May 12, 2026 through June 23, 2026.

The complaint alleges defendants made materially false and misleading statements about Hyliion's commercial pipeline. It alleges they touted the VFG Holdings partnership without disclosing material information about VFG’s operational capabilities, financial resources, and ability to perform.

According to the complaint, HYLN fell 17% on June 23, 2026, after the report, then declined another 19% the following day.

Company Profile

Hyliion Holdings Corp. designs and develops power generators for stationary and mobile applications. Its primary product is the KARNO Power Module, a fuel-agnostic power generating solution that enables distributed power generation using conventional fuels, waste fuels, and zero carbon fuels.

Class Period

May 12, 2026 – June 23, 2026

Investors who purchased or acquired Hyliion Holdings Corp. (HYLN) common stock during the Class Period may be eligible to seek recovery under the federal securities laws.

Allegations

The complaint alleges that Hyliion provided investors with positive information about its financial growth, commercial pipeline, and commercialization progress for the KARNO Power Module. On May 12, 2026, the company announced first quarter 2026 results, highlighted completion of UL certification testing for the KARNO Power Module, reaffirmed full-year revenue guidance, and announced a new strategic partnership with VFG Holdings through a non-binding LOI.

According to the complaint, Hyliion described the VFG LOI as a significant data center opportunity involving deployment of up to 250 KARNO Cores, or 50 megawatts of power generation capacity, over five years. The company also stated that VFG develops turnkey data center solutions, including power infrastructure, compute systems, site development, and financing. Chief Executive Officer Thomas Healy told investors that the VFG partnership positioned Hyliion within next-generation data center deployments and later referred to signed non-binding LOIs representing about $400 million of potential revenue at then-current pricing.

The lawsuit claims those statements were materially false and misleading because Hyliion failed to disclose material information concerning the credibility and commercial viability of the VFG partnership. The complaint alleges the VFG opportunity represented approximately $133 million in potential revenue, or roughly one-third of Hyliion's reported $400 million commercial pipeline, making questions about VFG's ability to finance, develop, and perform under the proposed transaction material to investors.

The complaint further alleges defendants knew, should have known, or recklessly disregarded that their statements lacked a reasonable basis. The complaint claims defendants had access to non-public information about Hyliion's evaluation of VFG, the commercial credibility of the VFG LOI, and the basis for presenting the LOI as a significant component of the company's pipeline and growth strategy.

The Truth Emerges

On June 23, 2026, Pelican Way Research published a report questioning Hyliion's commercial pipeline, with particular focus on the LOI with VFG Holdings. The report allegedly raised red flags about the transparency of the VFG partnership and questioned whether the remaining pipeline was valid, given limited public disclosures about the purported commercial opportunities.

According to the complaint, Pelican Way Research reported that VFG was newly formed, incorporated on January 5, 2026, appeared to have only "4 employees," and maintained a "barely functioning website." The report also claimed that VFG lacked the operational and financial capacity to support the proposed partnership, including the absence of public funding information, Pitchbook funding data, or other funding history.

The complaint alleges that the report directly contradicted Hyliion's prior presentation of the VFG LOI as a meaningful data center partnership and substantial commercial opportunity. The complaint also points to Hyliion's second quarter 2026 earnings call on August 12, 2026, where defendants allegedly did not publicly rebut the short report but continued to tout customer demand while acknowledging that most customer interest was not yet reflected in LOIs or purchase contracts.

Market Reaction

Hyliion's stock price declined from a closing price of $7.37 per share on June 22, 2026, to $6.10 per share on June 23, 2026, a decline of $1.27 per share, or about 17%. The complaint alleges this drop followed the Pelican Way Research report questioning the commercial viability of the VFG partnership and the company's broader pipeline.

The stock price continued to decline on June 24, 2026, falling another $1.18 per share, or 19%, to close at $4.92 per share. The complaint alleges the second-day decline occurred as the market continued to absorb the report's claims about VFG's operational capabilities, financial resources, and development experience.

Next Steps

        Lead Plaintiff Deadline: October 27, 2026

        After the lead plaintiff deadline, the Court will consider any lead plaintiff motions.

        Defendants may file a motion to dismiss.

        If the case proceeds, the Court may later consider class certification.
