Files Formal Complaints Against PwC with AICPA and PCAOB
J-Star’s
Complaints Allege PwC Misrepresented Qualifications During J-Star’s IPO, Delaying Process and Resulting in Additional Fees
Taichung
City, Taiwan – January 22, 2026 — J-Star Holding Co., Ltd. (Nasdaq: YMAT) (“J-Star” or the “Company”),
a leading provider of innovative carbon fiber and composite solutions serving diverse applications including personal sports equipment,
healthcare products, automobile parts, resin systems, and research and development services, today announced that the Company has filed
formal complaints against PwC with the American Institute of Certified Public Accountants (“AICPA”) and the Public Company
Accounting Oversight Board (“PCAOB”) regarding PwC’s misrepresentations during the Company’s NASDAQ IPO process.
The
AICPA complaint is currently under investigation.
As
the Company’s appointed auditor and consultant, PwC was expected to deliver professional, timely, and competent services in compliance
with relevant U.S. regulatory requirements. Regrettably, PwC’s services fell far short of these expectations, resulting in significant
delays and additional costs to J-Star’s U.S. IPO timeline. The Company inevitably had to replace PwC during the IPO and PwC’s
audited Financial Statements were questioned later by authorities in 2025 and become inadequate for our IPO in the first half
of 2025.
Jonathan
Chiang, Chairman of J-Star, commented, “J-Star is committed to the highest standards of transparency, regulatory compliance, and
investor protection. After a careful consideration, we determined that it was appropriate to bring these matters directly to U.S. regulatory
authorities to ensure an independent and objective review of the conduct at issue as the implications directly impacted our U.S. IPO
process and shareholders. Although PwC’s services for the IPO involved both its Taiwan and U.S. teams, at this stage the Company
has decided not to submit the case to the regulators overseeing PwC’s Taiwan team, i.e., the Financial Supervisory Commission (“FSC”).
One of the considerations is that the former Deputy Chairman of the FSC now serves as the Deputy Executive Director and Partner at PwC
Taiwan, which could raise concerns about FSC’s independence in handling the case fairly. We believe accountability is essential
to maintaining the integrity of the capital markets, and we will fully cooperate with the AICPA and PCAOB as their reviews proceed.”
