When Considering the Filing of a Securities Lawsuit, Choosing
the Right Law Firm Is Extremely Critical
In securities litigation, the defendant listed company is typically represented by a major law firm or a highly experienced team of attorneys that conducts an organized and meticulous defense. Accordingly, for shareholders to achieve satisfactory results, highly sophisticated litigation strategies—supported by extensive practical experience and a deep understanding of financial regulatory law—are essential.
Moreover, many major law firms already represent listed companies as clients and therefore are often unable, due to conflicts of interest, to accept engagements to represent shareholders in actions against those companies.
Our Securities Litigation Support Team
develops and implements comprehensive and robust defense strategies.
Each of our attorneys is distinguished by substantial experience in litigation and other dispute resolution matters.
Our Securities Litigation Support Team offers the following strengths, enabling us to effectively address the challenges faced by shareholders in securities litigation.
Response to Securities Litigation
Securities litigation refers to lawsuits in which shareholders who have suffered losses after purchasing securities in reliance on false statements or material misrepresentations in securities reports (such as annual securities reports) seek damages from the company that made such misstatements, as well as its officers/directors or other responsible parties.
Regarding the Nidec Matter
On September 3, 2025, Nidec Corporation announced that it had established a third-party committee after multiple materials were discovered that raised suspicions of inappropriate accounting treatment. Following this announcement, the company’s share price declined sharply.
The investigation by Nidec Corporation’s third-party committee remains ongoing, and future actions will need to be considered in light of the committee’s findings. According to the current schedule, the committee is expected to issue an interim report around the end of February 2026, which will clarify the investigation results as of that time. A final report by the third-party committee is also expected to be issued at a later date, although the timing has not yet been determined.
If the third-party committee’s report reveals issues such as material misstatements in the company’s securities reports, the matter may become subject to securities litigation. Accordingly, shareholders of the company may wish to consider potential legal actions, including the filing of claims against the company.
In securities litigation, plaintiffs must present complex and highly specialized arguments and evidence regarding the causal relationship between alleged misstatements in securities reports and the resulting decline in share price, as well as the extent of damages. Accordingly, retaining attorneys with the requisite knowledge and experience is critical to maximizing recovery through litigation.
