Rosen Law Firm represents:The firm encourages investors to choose lawyers who are qualified and have a successful track record in leading roles. It is stated that law firms issuing similar notices often lack comparable experience, resources, or meaningful recognition from their peers. Many of these firms do not actually handle securities class actions themselves but rather refer clients or collaborate with law firms that are responsible for the litigation. Rosen Law Firm claims to represent global investors, with a focus on securities class actions and shareholder derivative lawsuits. The firm has reportedly reached the largest securities class action settlement in history against a Chinese company; it was ranked first by ISS Securities Class Action Services in terms of the number of securities class action settlements in 2017; it has been in the top four every year since 2013; and has recovered billions of dollars in compensation for investors. The firm also mentioned that in 2019 alone, it secured over $438 million in compensation for investors. In 2020, the founding partner Laurence Rosen was recognized by law360 as a “Titan” in the field of plaintiff attorneys, and several lawyers have received recognition from Lawdragon and Super Lawyers.

Case details:According to the indictment, the defendant made false and/or misleading statements regarding the credibility of its announced business initiatives, and/or omitted significant facts, particularly concerning the management's basis for confidence in its partnership with VFG Holdings (“VFG”), as well as Hyliion's assessment of VFG's operational capabilities, financial resources, and ability to fulfill contractual obligations before announcing “new data center partnerships” as a major business opportunity. The lawsuit alleges that investors suffered losses as a result when the true circumstances became known to the market.

Collective certification has not yet been completed.Before the court recognizes the collective, unless you hire a lawyer on your own, you will not be represented by one. You can choose a lawyer yourself, or you can opt to remain an anonymous member of the collective without taking any action for now. Whether investors will be able to share in any potential compensation in the future does not depend on whether they serve as the lead plaintiff.
