HYLN SHAREHOLDER INVESTIGATION: Levi & Korsinsky Investigates Hyliion Holdings Corp. For Possible Securities Law Violations

NEW YORK CITY, NY / ACCESS Newswire / June 26, 2026 / Levi & Korsinsky notifies investors that it has commenced an investigation into Hyliion Holdings Corp. ("Hyliion Holdings Corp.") (NYSE:HYLN) concerning potential violations of the federal securities laws.

Hyliion Holdings lost 13-17% of its share price in a single trading session after a short-seller report challenged the credibility of a $133 million deal that represented roughly one-third of the company's disclosed pipeline.

Hyliion's Q1 2026 10-Q, filed May 12, 2026, disclosed that a single unidentified customer accounted for 100% of quarterly revenue. The filing did not name the customer or address concentration risk. During the same period, management publicly described a pipeline of "nearly 500 units under non-binding letters of intent" across multiple customers on its Q4 2025 earnings call on February 25, 2026.

The company's 10-K for fiscal year 2025, filed February 25, 2026, contained no reference to the $133 million AI-data-center LOI with VFG Holdings. CEO Thomas Healy signed a Sarbanes-Oxley Section 302 certification on the same filing, attesting that it did not omit any material fact necessary to make the statements made not misleading.
