J-Star Holding Co. Ltd., a provider of carbon fiber and composite solutions, has filed formal complaints against PwC with the American Institute of Certified Public Accountants (AICPA) and the Public Company Accounting Oversight Board (PCAOB). The company alleges that PwC misrepresented its qualifications during J-Star’s NASDAQ IPO process, leading to delays and additional costs. J-Star ultimately replaced PwC as its auditor after authorities questioned PwC’s audited financial statements, which were deemed inadequate for the IPO in the first half of 2025. The AICPA is currently investigating the complaint.
